BACKGROUND. There is a national trend to deinstitutionalize mentally r
etarded adults, placing them in community residential settings, As a r
esult, community-based primary care physicians will assume responsibil
ity for their medical care, Primary care physicians may have uncertain
ties regarding the medical care of this population. The purpose of thi
s case series is to describe the medical care of a group of adults wit
h mental retardation during their first year of community residence fo
llowing deinstitutionalization, and to provide practical advice to fam
ily physicians who care for these adults. METHODS. Medical diagnoses a
nd medications at the time of deinstitutionalization of a series of 21
adults were abstracted from institutional records and transfer forms,
Follow-up data were obtained from office medical records. RESULTS. In
the first year following deinstitutionalization, each patient average
d 6.6 office visits to a family physician, Newly identified major heal
th impairments were: chronic persistent hepatitis due to hepatitis B,
acid peptic disease, gastroesophageal reflux disease, dysphagia, prima
ry degenerative dementia, absence seizures, bronchiectasis, and idiopa
thic iridocyclitis. Significant changes in pharmacotherapy included co
nsolidation of multidrug anticonvulsant regimens and discontinuance of
psychotropics and laxatives. Health maintenance practices included he
patitis B immunizations, cholesterol determinations, smoking cessation
counseling, and calcium supplementation. CONCLUSIONS. Newly deinstitu
tionalized patients require careful diagnostic and therapeutic reasses
sment. Family physicians assuming their care need to look for conditio
ns common in this population, including dysphagia, seizure disorders,
chronic hepatitis B, and sensory impairments. Previously neglected hea
lth maintenance practices need to be instituted, Pharmacotherapies, pa
rticularly anticonvulsants, psychotropics, and laxatives, may be amena
ble to dosage reduction or discontinuance.
