Survival prognosis in geriatric patients admitted to permanent institutional care.
The influence of clinical and laboratory findings on the two-year survival prognosis was investigated in 558 geriatric patients admitted to permanent institutional care. The patients surviving for two years (52%) were somewhat younger (79 vs 82 years, p less than 0.01), and on admission had significantly higher diastolic blood pressure (p less than 0.001), serum thyroxin (p less than 0.05), serum albumin (p less than 0.01) and blood haemoglobin (p less than 0.05), but lower treatment score (p less than 0.001), serum creatinine (p less than 0.001), and fasting plasma glucose (p less than 0.05). Decreased survival prognosis was also found in patients with abnormal serum sodium, chloride, and potassium (p less than 0.05 or less). However, an excess mortality of patients with abnormal laboratory data occurred within the first month after admission. Stepwise logistic regression analysis disclosed that the three-month survival prognosis was significantly impaired by low blood pressure (less than 110/70 mmHg), high treatment score (greater than 22), elevated serum creatinine (greater than 150 mumol/L), use of digitalis and atrial fibrillation. Poor two-year survival was further associated with the use of diuretics, and diabetes mellitus. The risk for death was lowest in patients with elevated blood pressure (greater than 160/95 mmHg). These data verify the significance of the clinically common diseases and indicators of homeostasis in the assessment of geriatric hospital patients, and demonstrate the nature of "terminal decline" in geriatric practice.
