INTRODUCTION: The aim of this study was to evaluate the prescription drugs and reasons for hospital admission among elderly patients. METHODS: A single-center, retrospective study between November 2013 and December 2013 was conducted using the medical records of elderly patients (≥65 years of age) admitted to the outpatient clinic. Demographic characteristics of patients, diagnoses and prescription drugs were evaluated. RESULTS: A total of 293 elderly patients (152 female, 141 male) attending a outpatient clinic were included in the study. The mean age was 72.15±7.1 for the male patients, and 71.84±5.2 for the females. Only 2% of the patients had no health insurance. The most common reasons for hospital admission were irritable bowel syndrome (12.5%), abdominal and/or pelvic pain (11.6%), gastroesophageal reflux disease (9.8%), essential hypertension (8.5%), benign thyroid neoplasm (7.7%) and noninsulin-dependent diabetes (7%), respectively. Nearly half of the patients did not receive any medication (%45), only 8.8% of them received five and more drugs. The total number of drugs prescribed were 473 and ranged from 0 to 9 drugs per patient. The most commonly prescribed drugs were cardiovascular system drugs (20.2%), nonsteroidal anti-inflammatory drugs (16.7%), gastraointestinal drugs (14.1%), respectively. DISCUSSION AND CONCLUSION: Our data showed that cardiovascular drug use and pain were common among the old patients. Not only drug treatment, a multidisciplinary approach should be used for pain control. A careful history and physical examination are crucial to prevent polypharmacy and inappropriate medication use in elderly.
