Pattern and outcome of medical admission of elderly patients seen at University of Ilorin Teaching Hospital, Ilorin.

The elderly are increasingly been hospitalised into medical wards in Nigeria and little information is currently available on this group of patients. The objective of this study was to describe the demographic, clinical characteristics and outcome of management of elderly patients admitted into medical wards at the University of Ilorin Teaching Hospital Ilorin, Nigeria. A retrospective study in which hospital records of patients admitted between years 2001 to 2004 were reviewed. Information obtained included gender, occupation, diagnosis, investigations, duration of stay and outcome management. A total of 4113 adults were admitted into the medical wards within the period under review. Of these, 456 were aged 60 years and above. The elderly patients accounted for 11.1% of total hospitalisation into the medical wards. The mean age of the patients was 69 +/- 9 years with male:female ratio of 243:105. The 3 most common diagnoses were: hypertensive heart failure (HHF), 19%; cerebrovascular accident (CVA), 12%; and tuberculosis (TB), 11%. The mean duration of hospitalisation was 15.6 +/- 13.8 days. Cases of mortality had significantly higher value of mean serum potassium, urea and creatinine, compared to those with favourable outcome and were eventually discharged home. A total of 192 patients (55.2%) were discharged home, while 109 (31%) died giving in-hospital mortality of 31.7%. Majority of the deaths (75%) occurred within 14 days of hospitalisation. Significantly higher number of patients died within the first seven days compared to those discharged (P<0.01). The mean duration of hospital stay was 15.6 +/- 13.8 days. Patients with favourable outcome spent a mean of 18.5 +/- 14.1 days while cases of mortality had a mean of 10.4 +/- 8.8 days in hospital before death. Geriatric patients constituted more than a tenth of total hospitalisation into UITH medical wards. They accounted for a significant proportion of in-hospital mortality. Since a third of the death occurred within the first few days of admission, improvement in the management of acute medical cases especially in the elderly is urgent needed. This will ensure survival of greater number of patients and thus reduces mortality.
