ABSTRACT
<b>Introduction</b> : This study was conducted to estimate actual reasons for encounters and health problems, which is difficult to assess in a free-access system, in an area with limited access to advanced care by using the International Classification of Primary care second edition (ICPC-2).<br><b>Methods</b> : We conducted a retrospective open cohort study on an isolated island in Okinawa Prefecture, Japan. We encoded reasons for encounter (RFE) and health problems of all patients using ICPC-2.<br><b>Results</b> : The total number of visits to the clinic was 5682 a year (age 0-14 years, n=862 ; age 15-64 years, n=2205 ; age 65 or older, n=2615). The top 3 RFE classified by organic systems were R (respiratory), S (skin) and L (musculoskeletal). Dementia (ICPC-2 code : P-70) was eighth in the rank of chronic health problem among elderly people. Visits due to health maintenance/prevention (ICPC-2 code : A-98) was third in the rank of new health problem among children.<br><b>Conclusion</b> : In the present study, rankings of major RFE and health problems are similar to those in previous studies. Among elderly people, however, the rank order of dementia among chronic health problems was higher than that in previous studies. In addition, among children, the rank order of health maintenance/prevention among new health problems was higher than that in previous studies.
ABSTRACT
Objective<br> The purpose of this study is to evaluate the differences in the reasons for visits to a Tokyo hospital before and after the changing of the name of the outpatient service from “internal medicine” to “general practice.” <br>Methods<br> The participants in this study were outpatients who visited the internal medicine department from September to October, 2006, and the general practice department from September to October in 2008, for their first medical examination at a hospital in Tokyo. <br>We encoded the reasons for the hospital visits using ICPC-2 (International Classification of Primary Care-2), and counted the number of reasons for each outpatient. <br>Results<br> In the internal medicine service, there were 362 outpatients participants (193 men and 169 women) with an average age of 48.6 years. In the general practice service, the participants consisted of 376 outpatients (206 men and 170 women) with an average age of 50.5 years. The difference between the total number of reasons for visits to the general practice service (1.7 ± 0.9 per visit) and to the internal medicine service (1.5 ± 0.8 per visit) was statistically significant. However, no significant differences were found between the two in terms of the proportion of the frequency for each category of reasons. <br>Conclusion<br> This study found that the changing of the name of the outpatient service from “internal medicine” to “general practice” led to a slight but statistically significant increase in the total number of reasons per visit. However, this change had no effect on the frequency for each category of reasons as a proportion of the total.
