Background. People older than 90 years represent an increasing segment of t
he US population, but little information exists on their hospitalization fo
r acute illness.
Methods. We retrospectively analyzed the clinical characteristics of patien
ts aged 95 through 99 years admitted during 1 year to a large teaching hosp
ital.
Results. Of 43 patients admitted at least once, 14 were admitted twice, 6 w
ere admitted three times, and 1 was admitted four times; 35 (81%) were wome
n, and 8 (19%) were men. Patients admitted more than once took a mean of 6.
8 +/- 3.3 drugs compared with 4.4 +/- 2.6 drugs for patients admitted only
once, Routine laboratory values were typically normal or mildly abnormal. M
ean hospitalization was 5.6 +/- 3.5 days. Only 2 patients (5%) died. All 11
patients with a recent fall were discharged to a long-term nursing facilit
y, compared with only 18 of 30 patients without a recent fall.
Conclusions. Patients aged 95 through 99 years generally have a favorable p
rognosis when hospitalized for an acute medical condition. However, patient
s with a recent fall are more likely to require placement in a long-term nu
rsing facility, and patients taking six or more drugs on admission are more
likely to be rehospitalized within 12 months.
