- May 10, 2016 – Olanzapine : The U.S. Food and Drug Administration (FDA) is warning that the antipsychotic medicine olanzapine can cause a rare but serious skin reaction that can progress to affect other parts of the body. FDA is adding a new warning to the drug labels for all olanzapine-containing products that describes this severe condition known as Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS).
Levels of evidence (I–III) are defined at the end of the "Major Recommendations" field.
Preventive Care Checklist for Adults with Developmental Disabilities (DD)
Recommendations are listed with associated considerations under each subheading below.
General Issues in Primary Care of Adults with DD
Consideration: Disparities in primary care exist between adults with DD and the general population. The former often have poorer health, increased morbidity, and earlier mortality. Assessments that attend to the specific health issues of adults with DD can improve their primary care.
Recommendation: Apply age- and sex-specific guidelines for preventive health care as for adults in the general population (Dubey et al., 2006; Iglar et al., 2008). Perform an annual comprehensive preventive care assessment including physical examination and use guidelines and tools adapted for adults with DD (Lennox et al., 2007). (Level I)
Consideration: Etiology of DD is useful to establish, whenever possible, as it often informs preventive care or treatment.
Recommendation: Contact a genetics centre for referral criteria and testing protocols concerning etiologic assessment of adults whose DD is of unknown or uncertain origin (Curry et al., 1997; Diraimo et al., 2009; University of Washington, 1993). (Level III)
Consideration: Advances in genetic knowledge continue to enhance detection of etiology.
Recommendation: Consider reassessment periodically if a previous assessment was inconclusive, according to the criteria of the genetics centre (Moeschler, 2008). (Level III)
Consideration: Adaptive functioning can decline or improve in some adults with DD. A current assessment of intellectual and adaptive functioning helps to determine necessary care and supports, and establishes a baseline for future assessment.
Recommendation: Refer to a psychologist for assessment of functioning if the patient has never been assessed during adolescence or adulthood, or if a considerable life transition is expected (e.g., cessation of schooling or transition from middle to old age). (Level III)
Recommendation: Consider reassessment if indicated, comprehensively or in specific areas, to determine contributing factors to problem behaviour (see "Problem Behaviour," below) (The AAIDD Ad Hoc Committee on Terminology and Classification, 2010). (Level III)
Pain and Distress
Consideration: Pain and distress, often unrecognized, might present atypically in adults with DD, particularly those who have difficulty communicating. Nonspecific changes in behaviour might be the only indicator of medical illness or injury.
Recommendation: Be attentive to atypical physical cues of pain and distress using an assessment tool adapted for adults with DD (Regnard, Matthews, & Gibson, 2008; Burkitt et al., 2009). (Level III)
Consideration: Evaluation tools are available to assess the presence and intensity of pain in adults with DD.
Recommendation: Consider medical causes of changes in behaviour (e.g., urinary tract infection, dysmenorrhea, constipation, dental disease) (Regnard et al., 2007). (Level III)
Multiple or Long-term Use of Some Medications
Consideration: Multiple or long-term use of some medications by adults with DD can cause harm that is preventable.
Recommendation: Review the date of initiation, indications, dosages, and effectiveness of all medications regularly (e.g., every 3 mo) (Lennox, 2005). (Level III)
Recommendation: Determine patient adherence capacity and recommend dosettes, blister-packs, and other aids if necessary. (Level III)
Recommendation: Watch for both typical and atypical signs of adverse effects (Beange, Lennox, & Parmenter, 1999). Regularly monitor potentially toxic medications or interactions of medications (e.g., liver function tests or serum drug levels) at the recommended interval for each medication (Bhaumik & Branford, 2008). (Level III)
Recommendation: Ensure that patient and staff or caregivers are educated about appropriate use of medications, including over-the-counter, alternative, and as-needed medications. (Level III)
Abuse and Neglect
Consideration: Abuse and neglect of adults with DD occur frequently and are often perpetrated by people known to them. Behavioural indicators that might signal abuse or neglect include unexplained change in weight, noncompliance, aggression, withdrawal, depression, avoidance, poor self-esteem, inappropriate attachment or sexualized behaviour, sleep or eating disorders, and substance abuse.
Recommendation: Screen annually for risk factors (e.g., caregiver stress) and possible behavioural indicators of abuse or neglect (Fudge Schormans & Sobsey, 2007). (Level III)
Recommendation: When abuse or neglect is suspected, report to the police or other appropriate authority and address any consequent health issues (e.g., through appropriate counseling) (Fudge Schormans & Sobsey, 2007). (Level III)
Capacity for Voluntary and Informed Consent
Consideration: Capacity for voluntary and informed consent varies with the complexity and circumstances of decision making. The limited range of life experiences of some adults with DD, level of intellectual functioning, learned helplessness, and some mental health issues might impair capacity to give informed or voluntary consent. An adult with DD assessed as incapable of some aspects of decision making (e.g., understanding or judging consequences) might still be able to convey, through verbal or other means, perspectives that can inform the judgment of a substitute decision maker.
Recommendation: Always assess capacity for consent when proposing investigations or treatments for which consent is required (Friedman, 1998). (Level III)
Consideration: Communicating appropriately with adults with DD is necessary for assessing their capacity to consent and for seeking this consent.
Recommendation: Adapt the level and means of communicating to the patient's level of intellectual and adaptive functioning (van Schrojenstein Lantman-de Valk & Walsh, 2008). (Level III)
Consideration: Although some adults with DD might be incapable of giving consent, they might be able to contribute to decision making (e.g., understanding information, expressing perspectives, giving assent) with appropriate support from regular caregivers. Caregivers can also contribute to decision making. They may consent to or refuse treatment on behalf of an adult with DD who is assessed to be incapable of providing informed consent, if they are the most appropriate and available substitute decision makers according to the law.
Recommendation: Always consider the best interests of the adult with DD, including his or her perspective in pursuing or forgoing any health care intervention. Support whatever decision-making capacity is possible in adults with DD. Involve family or other caregivers to facilitate communication with, and understanding of, the adult with DD, but also be attentive to inappropriate taking over of decision making (Tuffrey-Wijne & McEnhill, 2008; Rush & Frances "Guideline 2," 2000). (Level III)
Advance Care Planning
Consideration: Advance care planning can often make a positive difference to the outcome of difficult life transitions and crises, and for end-of-life care.
Recommendation: Discuss advance care plans with adults with DD and their caregivers, especially to determine their preference of a substitute decision maker (Friedman, 1998). (Level III)
Recommendation: Record advance care plans and review them annually, or sooner in the context of a health crisis, for appropriateness to the adult with DD's present situation and for what needs to be implemented (van Schrojenstein Lantman-de Valk & Walsh, 2008). (Level III)
Interdisciplinary Health Care
Consideration: Interdisciplinary health care is effective in addressing the complex needs of adults with DD. Ideally this would involve a family physician, nurse, and other health practitioners as required, with a coordinator, who might be the family physician, to ensure continuity of care.
Recommendation: Involve other available health professionals as needed (Crocker, 2006). To address complex physical, behavioural, or mental health needs, consult available regional service coordination agencies or specialized interdisciplinary teams (Ministry of Community and Social Services, 2008; Ministry of Community and Social Services, 2009). (Level III)
Physical Health Guidelines for Adults with DD
Physical Inactivity and Obesity
Consideration: Physical inactivity and obesity are prevalent among adults with DD and are associated with adverse outcomes, including cardiovascular disease, diabetes, osteoporosis, constipation, and early mortality. Being underweight, with its attendant health risks, is also common.
Recommendation: Monitor weight and height regularly and assess risk status using body mass index, waist circumference, or waist-hip ratio measurements (Health Canada, 2003; Bhaumik et al., 2008). (Level II)
Consideration: A health promotion program can improve attitudes toward physical activity and satisfaction with life.
Recommendation: Counsel patients and their caregivers annually or more frequently, if indicated, regarding guidelines for nutrition and physical fitness and how to incorporate regular physical activity into daily routines. Refer to dietitian if indicated (Marks, Sisirak, & Heller, 2010; Healthy Living Unit, Public Health Agency of Canada, 2003; Hamilton et al., 2007; Henderson et al., 2008). (Level II)
Vision and Hearing Impairments
Consideration: Vision and hearing impairments among adults with DD are often underdiagnosed and can result in substantial changes in behaviour and adaptive functioning.
Recommendation: Perform office-based screening of vision and hearing (e.g., Snellen eye chart, whispered voice test) annually as recommended for average-risk adults, and when symptoms or signs of visual or hearing problems are noted, including changes in behaviour and adaptive functioning (Beange, Lennox, & Parmenter, 1999; Evenhuis & Natzgam, 1997). (Level III)
Recommendation: Refer for vision assessment to detect glaucoma and cataracts every 5 y after age 45 (Evenhuis & Natzgam, 1997). (Level III)
Recommendation: Refer for hearing assessment if indicated by screening and for age-related hearing loss every 5 y after age 45 (Evenhuis & Natzgam, 1997). (Level III)
Recommendation: Screen for and treat cerumen impaction every 6 mo (Crandell & Roeser, 1993; Roland et al., 2008). (Level III)
Consideration: Dental disease is among the most common health problems in adults with DD owing to their difficulties in maintaining oral hygiene routines and accessing dental care. Changes in behaviour can be the result of discomfort from dental disease.
Recommendation: Promote regular oral hygiene practices and other preventive care (e.g., fluoride application) by a dental professional (Ismail, Lewis, & Dingle, 1994; Lewis & Ismail, 1994; Dougherty & MacRae, 2006; Glassman & Miller, 2003). (Level I)
Consideration: Cardiac disorders are prevalent among adults with DD. Risk factors for coronary artery disease include physical inactivity, obesity, smoking, and prolonged use of some psychotropic medications.
Recommendation: When any risk factor is present, screen for cardiovascular disease earlier and more regularly than in the general population and promote prevention (e.g., increasing physical activity, reducing smoking) (Wallace & Schluter, 2008). (Level III)
Consideration: Some adults with DD have congenital heart disease and are susceptible to bacterial endocarditis.
Recommendation: Refer to a cardiologist or adult congenital heart disease clinic (Canadian Adult Congenital Health Network, 2009). (Level III)
Recommendation: Follow guidelines for antibiotic prophylaxis for those few patients who meet revised criteria (Wilson et al., 2007). (Level II)
Consideration: Respiratory disorders (e.g., aspiration pneumonia) are among the most common causes of death for adults with DD. Swallowing difficulties are prevalent in those patients with neuromuscular dysfunction or taking certain medications with anticholinergic side effects, and they might result in aspiration or asphyxiation.
Recommendation: Screen at least annually for possible signs of swallowing difficulty and overt or silent aspiration (e.g., throat clearing after swallowing, coughing, choking, drooling, long mealtimes, aversion to food, weight loss, frequent chest infections). Refer as appropriate (Chadwick & Jolliffe, 2009). (Level III)
Gastrointestinal and Feeding Problems
Consideration: Gastrointestinal and feeding problems are common among adults with DD. Presenting manifestations are often different than in the general population and might include changes in behaviour or weight.
Recommendation: Screen annually for manifestations of gastroesophageal reflux disease (GERD) and manage accordingly. If introducing medications that can aggravate GERD, monitor more frequently for related symptoms (Wallace et al., 2004; Böhmer et al., 2000). (Level III)
Recommendation: If there are unexplained gastrointestinal findings or changes in behaviour or weight, investigate for constipation, GERD, peptic ulcer disease, and pica (Morad et al., 2007; Böhmer et al., 2000). (Level II)
Consideration: Adults with DD might have an increased risk of Helicobacter pylori infection related to factors such as having lived in a group home, rumination, or exposure to saliva or feces due to personal behaviour or environmental contamination.
Recommendation: Screen for H pylori infection in symptomatic adults with DD or asymptomatic ones who have lived in institutions or group homes. Consider retesting at regular intervals (e.g., 3–5 y) (Wallace et al., 2004). (Level III)
Recommendation: Consider urea breath testing, fecal antigen testing, or serologic testing depending on the indication, availability, and tolerability of the test (Wallace et al., 2004; Bourke et al., 2005). (Level III)
Consideration: Sexuality is an important issue that is often not considered in the primary care of adolescents and adults with DD.
Recommendation: Discuss the patient's or caregiver's concerns about sexuality (e.g., menstruation, masturbation, fertility and genetic risks, contraception, menopause) and screen for potentially harmful sexual practices or exploitation. Offer education and counseling services adapted for those with DD (Wilkinson & Cerreto, 2008; Cox, Signore, & Quint, 2011). (Level III)
Consideration: Musculoskeletal disorders (e.g., scoliosis, contractures, and spasticity, which are possible sources of unrecognized pain) occur frequently among adults with DD and result in reduced mobility and activity, with associated adverse health outcomes.
Recommendation: Promote mobility and regular physical activity (Marks, Sisirak, & Heller, 2010; O'Neil et al., 2006). (Level III)
Recommendation: Consult a physical or occupational therapist regarding adaptations (e.g., wheelchair, modified seating, splints, orthotic devices) and safety (O'Neil et al., 2006). (Level III)
Consideration: Osteoporosis and osteoporotic fractures are more prevalent and tend to occur earlier in adults with DD than in the general population. In addition to aging and menopause, risk factors include severity of DD, low body weight, reduced mobility, increased risk of falls, smoking, hypogonadism, hyperprolactinemia, the presence of particular genetic syndromes (e.g., Down and Prader-Willi), and long-term use of certain drugs (e.g., glucocorticoids, anticonvulsants, injectable long-acting progesterone in women). Diagnosis and management of osteoporosis related to the side effects of current treatments can be challenging in adults with DD.
Recommendation: Periodically assess risk of developing osteoporosis in all age groups of male and female patients with DD. Those at high risk warrant regular screening starting in early adulthood (Brown & Josse, 2002; Zylstra et al., 2008). (Level III)
Recommendation: Recommend early and adequate intake or supplementation of calcium and vitamin D unless contraindicated (e.g., in Williams syndrome) (Brown & Josse, 2002). (Level III)
Consideration: Osteoarthritis is becoming more common with increasing life expectancy and weight gain, posing diagnostic and treatment difficulties.
Recommendation: Be aware of osteoarthritis as a possible source of pain (Haveman et al., 2010). (Level III)
Consideration: Epilepsy is prevalent among adults with DD and increases with the severity of the DD. It is often difficult to recognize, evaluate, and control, and has a pervasive effect on the lives of affected adults and their caregivers.
Recommendation: Refer to guidelines for management of epilepsy in adults with DD (Kerr et al., 2009). (Level III)
Recommendation: Review seizure medication regularly (e.g., every 3–6 mo). Consider specialist consultation regarding alternative medications when seizures persist, and possible discontinuation of medications for patients who become seizure-free (Kerr et al., 2009). (Level III)
Recommendation: Educate patients and caregivers about acute management of seizures and safety-related issues (Epilepsy Canada, 2009). (Level III)
Consideration: Endocrine disorders (e.g., thyroid disease, diabetes, and low testosterone) can be challenging to diagnose in adults with DD. Adults with DD have a higher incidence of thyroid disease compared with the general population.
Recommendation: Monitor thyroid function regularly. Consider testing for thyroid disease in patients with symptoms (including changes in behaviour and adaptive functioning) and at regular intervals (e.g., 1–5 y) in patients with elevated risk of thyroid disease (e.g., Down syndrome) (Beange, Lennox, & Parmenter, 1999). (Level III)
Recommendation: Establish a thyroid baseline and test annually for patients taking lithium or atypical or second-generation antipsychotic drugs (Bhaumik & Branford, 2008). (Level III)
Consideration: Currently there is no clear evidence of increased prevalence of diabetes in adults with DD, with some exceptions (e.g., Down syndrome). Diabetes management guidance has been developed for adults with DD and their care providers.
Recommendation: Consider screening for diabetes in adults with DD who are obese or who have sedentary lifestyles or hyperlipidemia. (Level III)
Consideration: Limited available data suggest that hypogonadism is common among men with DD. Substantial data are available on hypogonadism associated with specific syndromes (e.g., Prader-Willi syndrome).
Recommendation: Consider screening for hypogonadism and testosterone level at least once after full puberty is achieved, ideally at around age 18 y, and refer as appropriate if low levels are found (McElduff & Beange, 2003; McElduff, Center, & Beange, 2003). (Level III)
Infectious Disease Prevention and Screening
Consideration: Infectious disease prevention and screening. Even though immunization is a crucial component of preventive care, adults with DD might have limited awareness of immunizations.
Recommendation: Follow guidelines for routine immunization of adults (Langley & Faughnan, 2004; National Advisory Committee on Immunization [NACI], 2006). (Level III)
Recommendation: Ensure influenza and Streptococcus pneumoniae vaccinations are current and offered when appropriate ("23-valent pneumococcal polysaccharide vaccine," 2008). (Level III)
Recommendation: Discuss the human papillomavirus vaccine with female patients with DD between the ages of 9 and 26 y and, if appropriate, their substitute decision makers (NACI, 2007). (Level III)
Consideration: It is important to screen for infectious diseases (e.g., hepatitis B, human immunodeficiency virus [HIV], and H pylori) in adults with DD.
Recommendation: Screen for infectious diseases based on the patient's risk factors for exposure (for recommendations on H pylori see "Gastrointestinal and Feeding Problems," above). (Level III)
Consideration: Some adults with DD have an increased risk of exposure to infectious diseases (e.g., hepatitis A and B).
Recommendation: Offer hepatitis A and B screening and immunization to all at-risk adults with DD, (NACI, 2007; Mast et al., 2006; Advisory Committee on Immunization Practices, 2006) including those who take potentially hepatotoxic medications or who have ever lived in institutions or group homes (NACI, 2006). (Level III)
Consideration: Cancer screening is an essential aspect of preventive care. However, adults with DD are less likely than those in the general population to be included in preventive screening programs such as cervical screening, breast examination, mammography, and digital rectal examination. They are also less likely to do self-examination or to report abnormalities. Colorectal cancer risk is considerably greater for women than for men with DD.
Recommendation: Perform regular cervical screening for all women who have been sexually active (Quint & Elkins, 1997). (Level I)
Recommendation: Perform annual breast screening, including mammography, for female patients with DD aged 50–69 y (Morrison, 1994). (Level III)
Recommendation: Perform an annual testicular examination for all male patients with DD (Elford, 1994). (Level III)
Recommendation: Screen for prostate cancer annually using digital rectal examination from age 45 y for all male patients with DD (Feightner, 1994). (Level II)
Recommendation: Screen for colon cancer regularly in all adult patients with DD older than 50 y (Sullivan et al., 2004; Leddin et al., 2004). (Level I)
Behavioural and Mental Health Guidelines for Adults with DD
Consideration: Problem behaviour, such as aggression and self-injury, is not a psychiatric disorder but might be a symptom of a health-related disorder or other circumstance (e.g., insufficient supports).
Recommendation: Before considering a psychiatric diagnosis, assess and address sequentially possible causes of problem behaviour, including physical (e.g., infections, constipation, pain), environmental (e.g., changed residence, reduced supports), and emotional factors (e.g., stress, trauma, grief) (Bradley & Hollins, 2010). (Level II)
Consideration: Problem behaviours sometimes occur because environments do not meet the developmental needs of the adult with DD.
Recommendation: Facilitate "enabling environments" to meet these unique developmental needs as they will likely diminish or eliminate these problem behaviours (Banks et al., 2007). (Level III)
Consideration: Despite the absence of an evidence base, psychotropic medications are regularly used to manage problem behaviours among adults with DD. Antipsychotic drugs should no longer be regarded as an acceptable routine treatment of problem behaviours in adults with DD.
Recommendation: Regularly audit the use of prescribed psychotropic medication, including those used as needed (Deb, Clarke, & Unwin, 2006). Plan for a functional analysis (typically performed by a behavioural therapist or psychologist) and interdisciplinary understanding of problem behaviours. Review with care providers psychological, behavioural, and other nonmedication interventions to manage problem behaviours. Consider reducing and stopping, at least on a trial basis, medications not prescribed for a specific psychiatric diagnosis (Deb et al., 2009). (Level III)
Consideration: Psychiatric disorders and emotional disturbances are substantially more common among adults with DD, but their manifestations might mistakenly be regarded as typical for people with DD (i.e., "diagnostic overshadowing"). Consequently, coexisting mental health disturbances might not be recognized or addressed appropriately.
Recommendation: When screening for psychiatric disorder or emotional disturbance, use tools developed for adults with DD according to their functioning level (e.g., Aberrant Behaviour Checklist-Community [ABC-C]; Psychiatric Assessment Schedule for Adults with DD [PAS-ADD]) (Aman, Burrow, & Wolford, 1995; Moss et al., 1998; Mohr & Costello, 2007; Perez-Achiaga, Nelson, & Hassiotis, 2009). (Level III)
Consideration: Increased risk of particular developmental, neurologic, or behavioural manifestations and emotional disturbances (i.e., "behavioural phenotypes") is associated with some DD syndromes.
Recommendation: Consult available information on behavioural phenotypes in adults with DD due to specific syndromes (O'Brien, 2002; Society for the Study of Behavioural Phenotypes, 2009). (Level III)
Consideration: Establishing a diagnosis of a psychiatric disorder in adults with DD is often complex and difficult, as these disorders might be masked by atypical symptoms and signs. In general, mood, anxiety, and adjustment disorders are underdiagnosed and psychotic disorders are overdiagnosed in adults with DD.
Recommendation: When psychiatric disorder is suspected, seek interdisciplinary consultation from clinicians knowledgeable and experienced in DD. (Level III)
Consideration: Psychotic disorders are very difficult to diagnose when delusions and hallucinations cannot be expressed verbally. Developmentally appropriate fantasies and imaginary friends might be mistaken for delusional ideation, and self-conversation for hallucination.
Recommendation: Seek interdisciplinary input from specialists in psychiatry, psychology, and speech-language pathology with expertise in DD to help clarify diagnoses in patients with limited or unusual use of language (Bradley et al., 2009; Craft, Bicknell, & Hollins, 1985; Summers et al., "The interdisciplinary," 2002). (Level III)
Input and Assistance from Adults with DD and Their Caregivers
Consideration: Input and assistance from adults with DD and their caregivers are vital for a shared understanding of the basis of problem behaviours, emotional disturbances, and psychiatric disorders, and for effectively developing and implementing treatment and interventions.
Recommendation: Establish a shared way of working with patients and caregivers. Seek input, agreement, and assistance in identifying target symptoms and behaviours that can be monitored. (Level III)
Recommendation: Use tools (e.g., sleep charts, antecedent–behaviour-consequence [ABC] charts) to aid in assessing and monitoring behaviour and intervention outcomes (Summers et al. "Comprehensive screening," 2002; Hurley, 1997). (Level III)
Interventions Other Than Medication
Consideration: Interventions other than medication are usually effective for preventing or alleviating problem behaviours.
Recommendation: To reduce stress and anxiety that can underlie some problem behaviours, emotional disturbances, and psychiatric disorders, consider such interventions as addressing sensory issues (e.g., underarousal, overarousal, hypersensitivity), environmental modification, education and skill development, communication aids, psychological and behaviour therapies, and caregiver support (Bradley et al., 2009). (Level III)
Recommendation: Cognitive behavioural therapy can be effective in decreasing anger and treating anxiety and depression in adults with DD (McCabe, McGillivray, & Newton, 2006; Taylor, Lindsay, & Willner, 2008). (Level III)
Recommendation: There is increasing evidence of the efficacy of psychotherapy for emotional problems (e.g., related to grief, abuse, trauma) that might underlie aggression, anxiety, and other such states (Hollins & Sinason, 2000; Hubert & Hollins, 2006; McGinnity et al., 2004; Sequeira, Howlin, & Hollins, 2003; Cottis, 2008). (Level III)
Consideration: Psychotropic medications (e.g., antidepressants) are effective for robust diagnoses of psychiatric disorders in adults with DD as in the general population.
Recommendation: When psychiatric diagnosis is confirmed after comprehensive assessment, consider psychotropic medication along with other appropriate interventions as outlined in "Intervention Other Than Medication," above (Kalachnik et al., 1998). (Level III)
Consideration: Psychotropic medications, however, can be problematic for adults with DD and should therefore be used judiciously. Patients might be taking multiple medications and can thus be at increased risk of adverse medication interactions. Some adults with DD might have atypical responses or side effects at low doses. Some cannot describe harmful or distressing effects of the medications that they are taking.
Recommendation: "Start low, go slow" in initiating, increasing, or decreasing doses of medications (Rush & Frances "Guideline 4," 2000). (Level III)
Recommendation: Arrange to receive regular reports from patients and their caregivers during medication trials in order to monitor safety, side effects, and effectiveness (Deb et al., 2009). (Level III)
Recommendation: In addition to reviews every 3 mo (see "Multiple or Long-term Use of Some Medications," above), also review the psychiatric diagnosis and the appropriateness of prescribed medications for this diagnosis whenever there is a behavioural change (Bhaumik & Branford, 2008; Deb et al., 2009). (Level III)
Consideration: When unable to pinpoint a specific psychiatric diagnosis, behaviours of concern might serve as index behaviours against which to conduct a trial of medications.
Recommendation. Having excluded physical, emotional, and environmental contributors to the behaviours of concern, a trial of medication appropriate to the patient's symptoms might be considered. (Level III)
Consideration: Antipsychotic medications are often inappropriately prescribed for adults with behaviour problems and DD. In the absence of a robust diagnosis of psychotic illness, antipsychotic medications should not be regarded as routine treatments of problem behaviours in adults with DD.
Recommendation: Do not use antipsychotic medication as a first-line treatment of problem behaviours without a confirmed robust diagnosis of schizophrenia or other psychotic disorder (Tyrer et al., 2008). (Level III)
Consideration: Antipsychotic medications increase risk of metabolic syndrome and can have other serious side effects (e.g., akathisia, cardiac conduction problems, swallowing difficulties, bowel dysfunction).
Recommendation: Carefully monitor for side effects of antipsychotic medication, including metabolic syndrome. Educate patients and caregivers to incorporate a healthy diet and regular exercise into their lifestyle (Bhaumik & Branford, 2008). (Level III)
Recommendation: Reassess the need for ongoing antipsychotic medications at regular intervals and consider dose reduction or discontinuation when appropriate (also see "Multiple or Long-term Use of Some Medications" and "Psychotropic Medications," above) (Bhaumik & Branford, 2008). (Level III)
Consideration: Behavioural crises can occasionally arise that might need management in an emergency department.
Recommendation: When psychotropic medications are used to ensure safety during a behavioural crisis, ideally such use should be temporary (no longer than 72 h). (Level III)
Recommendation: Debrief with care providers in order to minimize the likelihood of recurrence. This should include a review of crisis events and responses (e.g., medication, de-escalation measures), and identification of the possible triggers and underlying causes of the behavioural crisis (Deb et al., 2009; Bradley & Lofchy, 2005). (Level III)
Recommendation: If the patient is at risk of recurrent behavioural crises, involve key stakeholders, including local emergency department staff, to develop a proactive, integrated emergency response plan (Bradley & Lofchy, 2005). (Level III)
Alcohol or Drug Abuse
Consideration: Alcohol or drug abuse is less common among adults with DD than in the general population, but the former might have more difficulty moderating their intake and experience more barriers to specialized rehabilitation services.
Recommendation: Screen for alcohol and drug abuse as part of the annual health examination. (Level III)
Consideration: Dementia is important to diagnose early, especially in adults with Down syndrome who are at increased risk. Diagnosis might be missed because changes in emotion, social behaviour, or motivation can be gradual and subtle. A baseline of functioning against which to measure changes is needed.
Recommendation: For patients at risk of dementia, assess or refer for psychological testing to establish a baseline of cognitive, adaptive, and communicative functioning. Monitor with appropriate tools (Royal College of Psychiatrists & British Psychological Society, 2009). (Level III)
Consideration: Differentiating dementia from depression and delirium can be especially challenging.
Recommendation: Educate family and other care providers about early signs of dementia. When signs are present, investigate for potential reversible causes of dementia. (Level III)
Recommendation: Consider referral to the appropriate specialist (i.e., psychiatrist, neurologist) if it is unclear whether symptoms and behaviour are due to emotional disturbance, psychiatric disorder, or dementia (Royal College of Psychiatrists & British Psychological Society, 2009). (Level III)
Criteria for Assigning Levels of Evidence
Level I: At least 1 properly conducted randomized controlled trial, systematic review, or meta-analysis
Level II: Other comparison trials, non-randomized, cohort, case control, or epidemiologic studies, and preferably more than 1 study
Level III: Expert opinion or consensus statements

Hand-searches of Published Literature (Secondary Sources)
Searches of Electronic Databases
A librarian familiar with research on developmental disabilities undertook ongoing, comprehensive electronic searches in PubMed and PsycINFO for publications in English from 1990 to 2010 that were indexed under, or contained in their title, abstract, or text, the terms mental retardation, intellectual disability (disabilities), or developmental disability (disabilities). Publications from Great Britain were also searched for the terms learning difficulties, learning disability (disabilities), or learning disorders. These were cross-referenced with a long list of physical and mental health key words relating to medical assessment, diagnosis, treatment, prognosis, health care access, need, planning, services, and delivery. The search was then expanded to include specific health issues highlighted in the 2006 Guidelines. In addition, the librarian undertook manual searches using cited references in Scopus and Internet searches for relevant publications that had not been indexed by any of the above-mentioned electronic databases. Search results were downloaded to and organized in an electronic database management system known as RefWorks.
Weighting According to a Rating Scheme (Scheme Given)
Criteria for Assigning Levels of Evidence
Level I: At least 1 properly conducted randomized controlled trial, systematic review, or meta-analysis
Level II: Other comparison trials, non-randomized, cohort, case control, or epidemiologic studies, and preferably more than 1 study
Level III: Expert opinion or consensus statements
The working group reviewed published supporting evidence for all the guidelines, including those from supplementary electronic and manual searches for publications undertaken after the colloquium to address particular issues that were not foreseen in the original literature searches. The working group judged the level of evidence supplied for any modified or new guidelines, using the classification scheme adopted in the 2006 Guidelines (see the "Rating Scheme for the Strength of Evidence" field).
Most of the recommendations specifically concerning adults with developmental disabilities in the updated guidelines are supported by Level III evidence based on expert opinion or published consensus statements. Three are based on randomized controlled trials, systematic reviews, or meta-analysis (Level I evidence), and 7 are based on less methodologically rigorous studies (Level II). Even when Level I or II evidence for recommendations for the general population was found, but no Level I or II evidence relating specifically to people with developmental disabilities, it was thought prudent, in view of differences between these 2 groups, to reject, adapt, or formulate new guidelines based on expert opinion (Level III evidence) for these guidelines.
A consensus development method was used to update the 2006 Guidelines. This consisted of 2 steps: meticulous electronic and manual searches for relevant publications and discussion of recommended changes to the 2006 Guidelines by knowledgeable and experienced Canadian clinicians and researchers on primary health care of adults with developmental disabilities who participated in a consensus colloquium in March 2009 and in a subsequent working group.
Two family physicians, a psychologist, and a psychiatrist drew on the database of search results and on comments regarding the 2006 Guidelines gained from various users and reviewers. They were each assigned a section of the 2006 Guidelines for which they were to propose revisions.
Participants who helped to formulate the 2006 Guidelines and others who had completed training courses on the guidelines between 2006 and 2009 were invited to a day-long colloquium in Toronto, Ontario, in March 2009. Among the 39 participants were practitioners in family medicine, nursing, pediatrics, psychiatry, psychology, occupational therapy, and speech-language pathology. Before the colloquium, all had access to the librarian's entries into the RefWorks database and received a summary of feedback from users and reviewers of the 2006 Guidelines. The prepared proposals for revisions were discussed in small groups and in plenary sessions, and a summary of accepted revisions was presented and discussed at the end of the colloquium in relation to the priority criteria adopted in the 2006 Guidelines (see the table below). A working group consisting of 7 participants, with a family physician in the leading role, met monthly between March 2009 and March 2010 to draft the first version of the updated guidelines. They incorporated into the 2006 Guidelines the changes discussed and accepted during the colloquium.
Guideline Priority Criteria
|Importance||Guidelines that address the most prevalent health issues for people with developmental disabilities, especially the leading causes of ill health and death|
|Disparity||Guidelines that address an issue that would not be identified by public health initiatives or illness prevention measures that target the general population|
|Usefulness||Guidelines that can be practically implemented and evaluated; these refer to health problems that are easy to detect, for which the means of prevention and care are readily available, and which have health outcomes that can be monitored|
|Information||Guidelines that are supported by reliable clinical information and research evidence|

A formal cost analysis was not performed and published cost analyses were not reviewed.
External Peer Review
Internal Peer Review
The first draft of the updated guidelines was circulated for review by participants in the colloquium as well as several invited consultants who were unable to attend the colloquium. Based on the feedback received, the working group prepared the second and final draft between March and October of 2010. The final draft was sent to participants in the colloquium and review process for their approval; it was then submitted for review for publication.

The type of supporting evidence is identified and graded for each recommendation (see the "Major Recommendations" field).
Appropriate primary care of adults with developmental disabilities (DD), which may lead to:
- Improved quality of primary care of adults with DD
- Improved access to health care
- Improved state of health
- Prevention of suffering, morbidity, and premature death
- Psychotropic medications can be problematic for adults with developmental disabilities (DD) and should therefore be used judiciously. Patients might be taking multiple medications and can thus be at increased risk of adverse medication interactions. Some adults with DD might have atypical responses or side effects at low doses.
- Antipsychotic medications increase risk of metabolic syndrome and can have other serious side effects (e.g., akathisia, cardiac conduction problems, swallowing difficulties, bowel dysfunction).
- The aim of the original guideline document is to inform primary care providers of the most prevalent health issues of adults with developmental disabilities (DD) as a group and of the best approaches to management. However, any such set of guidelines will always be limited in their application by the reality that adults with DD are not a homogeneous group nor do they experience health disorders in the same way. These guidelines are not meant to replace attentive observation and prudent clinical decisions. The most appropriate care for an adult with DD takes into account relevant factors in his or her particular circumstances. Furthermore, although these guidelines are generally applicable to adults with DD, primary care providers will need to address additional specific health issues when there is a known cause of DD.
- The division of these guidelines into distinct physical, behavioural, and mental health categories was intended to facilitate their application. Several guidelines, however, address the interaction of physical factors with behavioural and mental health ones, and between these and environmental factors and other determinants of health.
- Some of these updated guidelines recommend the use of resources and specialized services that, while generally available in Canada, might be lacking or inaccessible in some regional health service systems. In such circumstances, it is necessary to adapt these guidelines to allow primary care providers to provide a reasonable standard of care and to develop practical resource-sharing strategies (e.g., using clinical videoconferencing).
An implementation strategy was not provided.
