M. Pahor et al., DISABILITY AND SEVERE GASTROINTESTINAL HEMORRHAGE - A PROSPECTIVE-STUDY OF COMMUNITY-DWELLING OLDER PERSONS, Journal of the American Geriatrics Society, 42(8), 1994, pp. 816-825
OBJECTIVE: To describe the occurrence of severe gastrointestinal bleed
ing in community-dwelling older persons and to examine whether disabil
ity is a risk factor for this life-threatening condition independent o
f other known predictors. DESIGN: Prospective cohort survey. SETTING:
Three communities of the Established Populations for Epidemiologic Stu
dies of the Elderly (EPESE). PARTICIPANTS: 8205 persons age greater th
an or equal to 68 years. MEASUREMENTS: The hospital discharge diagnose
s provided by the Medicare Provider Analysis and Review files and the
death certificates were prospectively surveyed for 3 years. Those with
at least 1 discharge diagnosis of gastrointestinal bleeding and who r
eceived a blood transfusion or died were identified as cases of severe
gastrointestinal hemorrhage. Physical disability, cognitive function,
smoking and alcohol intake habits, body mass index, blood pressure, c
hronic conditions, number of hospital admissions in past year and medi
cations taken were assessed at baseline. RESULTS: The occurrence rate
of severe gastrointestinal bleeding was 10.8 per 1000 person-years (24
1 events/22,277 person-years). In proportional hazards regression mode
ls, compared with no disability, greater than or equal to 1 disabiliti
es in the Rosow-Breslau scale (RR = 2.1, 95% CI = 1.5-2.9), and greate
r than or equal to 1 ADLs limitations (RR = 3.1, 95% CI = 2.1-4.6) ind
ependently predicted gastrointestinal hemorrhage after adjusting for a
ge, gender, body mass index, comorbidity, number of hospital admission
s, blood pressure, intake of coumarin, corticosteroids, aspirin and ot
her nonsteroidal antiinflammatory drugs. CONCLUSIONS: In this prospect
ive analysis, disability is an independent predictor of gastrointestin
al hemorrhage. Further studies are needed to explain the mechanisms by
which disability may cause gastrointestinal hemorrhage. Because physi
cal disability is potentially modifiable, strategies to lower the risk
of gastrointestinal bleeding should be evaluated.
