Transitioning patients with developmental disabilities to adult care

Systematic health checks provide great value

A health check is a systematic and comprehensive health assessment that is provided annually to adults with IDD, and includes:

• specific review of signs and symptoms of health conditions that often co-­occur in adults with IDD (TABLE 2Calibri¹¹)
• screening for changes in adaptive functioning and secondary disability
• lifestyle counseling
• medication review and counseling
• immunization update
• discussion of caregiver concerns.

Successful implementation of preventive health screening tests for a patient with IDD often requires ingenuity and creativity to allay fears and anxieties.

Regarding the last point: Many caregivers are the aging parents of the adult patient with IDD—people who have their own emerging health and support needs. You should initiate conversations about advanced planning for the needs of patients, which often involves engaging siblings and other family members to assume a greater role in caregiving.¹²

Benefits of the health check. A systematic review of 38 studies, comprising more than 5000 patients with IDD, found that health checks increased the detection of serious conditions, improved screening for sensory impairments, and increased the immunization rate.¹³ Although many patients with IDD generally understand the need for a periodic health examination, you can enhance their experience by better explaining the rationale for the health check; scheduling sufficient time for the appointment, based on the individual clinical situation; and discussing the value of laboratory testing and referrals to specialists.¹⁴

Tailoring preventive care

Many of the preventive services recommendations typically utilized by family physicians, such as guidelines from the US Preventive Services Task Force, have been developed for the general population at average risk of conditions of interest.¹⁵ Adults with IDD, depending on the cause of their developmental disability and their behavioral risk profile, might be at significantly higher (or lower) risk of cancer, heart disease, or other conditions than the general population. To address these differences, preventive care guidelines tailored to patients with certain developmental disabilities have been created, including guidelines specific to adults with Down syndrome, fragile X syndrome, Prader-Willi syndrome, Smith-Magenis syndrome, and 22q11.2 deletion (DiGeorge) syndrome.¹⁶

Clarifying the molecular genetic etiology of many developmental disabilities has led to more precise understandings about physical and behavioral health issues associated with specific developmental disabilities. For that reason, patients without a known cause for their IDD might benefit from referral to a geneticist—even in early or middle adulthood. Variables generally associated with a higher likelihood of an abnormal genetic test result include¹⁷:

• a family history of developmental disability
• a congenital malformation or dysmorphic features
• a dual diagnosis of developmental disability and co-occurring mental illness
• hypotonia
• severe or profound IDD.
