Trends of the New Outpatients in a University-based Family Practice

Analysis of outpatient visits to primary care offers essential data for residency training by understanding 'reasons for encounter (RFE).' This study was designed to recognize the effect of population aging on demographic characteristics and RFEs. We included all patients who had visited family practice clinic in Kyung Hee University Hospital in Seoul during each first 5 working days of September, October, and November in 2001 and 2008. New patients included those who hadn't visited within the last 6 months or more. Information on each patient's age, sex, and reason for encounter was obtained from the electronic medical record. The RFEs were compared using International Classification of Primary Care (ICPC)-2-E. Mean age of overall outpatients was 50.5 and 52.4 years in 2001 and 2008 respectively. The number of new outpatient visits increased from 215 (21.3%) to 326 (29.7%) between 2001 and 2008 (P < 0.001) along with the number of patients aged 65 or more from 7.4% to 12.0% (P = 0.08). Mean age of established patients was 52.5 and 56.9 years (P < 0.001), and the patients aged 65 or more was 14.1% and 35.8% (P < 0.001) in 2001 and 2008 respectively. Analysis by ICPC-2-E revealed a decrease in chapter A in 2008 (P = 0.03) and an increase in chapter F, L, and X (P = 0.01, 0.003,
