The fractured lens: a controversial revision of the International Classification of Primary Care

Background

The International Classification of Primary Care (ICPC) has represented the international standard reduction for measuring the content of primary care for over 30 years. In the process of its third revision, its authors, the Wonca International Classification Committee (WICC), delegated a major part of the technical work to a purposely formed Consortium. However, in the process of such revision, standard classification principles and rules have been inconsistently applied with the result that ICPC-3 has been published with major errors and an inconsistent structure.

Objectives

To formally describe and critically appraise the revision process of ICPC-3.

Methods

The formal review of ICPC-3 performed by an expert group within WICC and commissioned by the Executive Council of Wonca Europe is presented in abridged form.

Results

ICPC-3 as currently presented introduces major departures from formal classification principles and rules, besides other major errors and inconsistencies, all of which are listed and described.

Conclusion

Major changes in ICPC-3 defy categorisation and conceptualisation standards. ICPC-3 now represents an untested departure from international standard presentations, without a formal academic base. The direct inclusion of measures of functioning in a classification of reasons for encounter and health problems fails to address the dichotomy of these domains, the boundaries of and relationships between which are not satisfactorily resolved by the system. Analysis of ICPC-3 data will require the development and implementation of alternative, as yet undefined, models of the relationships between disease and health. By including different domains without resolving ambiguity, and by splitting function from other body systems, ICPC-3 becomes an internally fractured instrument.

Descriptive Study of Patients Treated in a Psychosomatic Internal Medicine Declared by Japanese Family Medicine Clinic

Background

Psychosomatic internal medicine (PSIM) assesses psychosocial factors and provides holistic consideration. In Japan, PSIM physicians seem to be recognized as providers of mental health services, but family medicine did not so. When family physicians confront with psychological problems, high dropout rate is reported so it is needed to reveal factors related to dropouts, The purpose of this study is to describe characteristics of patients, treatment dropouts and its related factors in PSIM practice by family physician.

Methods

This cross-sectional study used data from the medical records of the Kitaibaraki Center of Family Medicine located in Kitaibaraki City, Ibaraki, Japan. The study included all new patients who made an appointment and visited the PSIM in this clinic from January 2020 to December 2022.Chief complaints and diagnoses were coded based on the International Classification of Primary Care, version 2 (ICPC-2).

Results

In total, 377 new patients were included in this study. The mean age was 39.9 ± 20.2 years. We found that 69.2% of patients who visited the clinic had a psychological chief complaint and 84.1% of primary diagnoses consisted of a psychological problem. One hundred sixty-five patients (43.8%) were still receiving treatment 6 months after the initial visit. Of the patients who ended treatment within 6 months after the initial visit, 84 patients (39.2%) dropped out. In multivariate analysis, the dropouts were less likely to occur patients with primary diagnosis of psychological problem (odds ratio (OR): 0.35, 95% confidence interval (CI): 0.19 - 0.67).

Conclusions

Patients who visited a PSIM wanted consultation about psychological problems. Patients with a diagnosis of a psychological problem at the initial visit were less likely to drop out.

First-visit patients without a referral to the Department of Internal Medicine at a medium-sized acute care hospital in Japan: an observational study

PURPOSE

We sought to profile first-time patients without a referral who sought medical care at the Department of Internal Medicine at a medium-sized acute care hospital in Japan. We anticipated that the analysis would highlight the demand for medical care needs from acute care hospitals and help confirm one of the problems associated with primary care in Japan.

PATIENTS AND METHODS

The study population comprised 765 patients who sought outpatient consultation without a referral at "the Department of General Internal Medicine" at the Ikeda City Hospital on Fridays over 4 years. Data on the following variables were collected: age, sex, examination date, reason for encounter (RFE), diagnosis, as well as history of consultation with or without antibiotic treatment at another medical institution for the same RFE. We used the International Classicication of Primary Care, Revised Second edition (ICPC-2-R) codes for RFEs and diagnoses.

RESULTS

The main RFE fields were digestive (ICPC-2-R Chapter D), general and unspecified (A), and respiratory (R). The main diagnosis fields were digestive (D), respiratory (R), general and unspecified (A), and musculoskeletal (L). In total, 27.6% of patients had sought consultation at another medical institution for the same RFE. Of these, 64.7% of patients for whom the RFE was cough (ICPC-2-R code, R05), and 72.0% for whom the RFE was fever (A03) were prescribed antibiotics. In total, 62.4% of patients underwent emergency investigations and waited for the results; 4.3% were hospitalized on the same day; and 60.5% were medicated at the initial examination. In 11.5%, the main underlying problem appeared to be psychosomatic.

CONCLUSION

We used the ICPC-2-R to analyze the state of first-visit patients without a referral visiting the Department of Internal Medicine at a medium-sized acute care hospital in Japan. Common RFEs were abdominal pain, cough, and fever. A tendency toward overprescription of antibiotics was observed among primary care physicians.

A chart review of morbidity patterns among adult patients attending primary care setting in urban Odisha, India: An International Classification of Primary Care experience

Introduction:

Disease burden estimations based on sound epidemiological research provide the foundation for designing health services. Patients visiting a primary care often present with symptoms and signs. Understanding the burden is crucial for developing countries including India. The project aimed to record the reasons for encounter (RFE) at primary care settings for estimating the burden at the health-care facility.

Methodology:

This cross-sectional study was undertaken at four urban health dispensaries of Bhubaneswar, Odisha, with the aim to explore the prevailing patterns of diseases among patients attending these facilities. Data collection spanned from May to October 2012. At each center, patients' information on age, sex, religion, and presenting illness was extracted from the outpatient records over these time period. Data were entered and analyzed in SPSS version 20, and the International Classification of Primary Care-2 was used for coding the illnesses.

Results:

In total, 2249 patient's records were extracted over 12 weeks. Out of them, 1241 (55.2%) were male with mean age of 41.8 (±15.8) years vis-à -vis 38.2 (±14.1) years for females. Around 151 (6.7%) had 2 or more symptoms or conditions. Overall, the most common categories were general and unspecified followed by digestive-related symptoms in both sexes. The most common symptoms among males were fever (11.4%), heart burn (8.1%), and vertigo or dizziness (3.6%). Similar pattern was seen among females. Respiratory (17.0%) and cardiovascular (10.2%) problems were the most common RFEs among males and females. The most common RFEs for acute care among males and females were fever, allergic rhinitis, upper respiratory tract infection, and acute bronchitis. Leading RFEs for chronic care among males were hypertension uncomplicated, heart burn, low back pain, whereas among females, hypertension and heartburn were mostly seen.

Conclusion:

Primary care settings are experiencing both communicable and non-communicable diseases along with injuries. Understanding the distribution of the diseases are essential to design appropriate service package at primary care.

Reasons for encounter and diagnoses of new outpatients at a small community hospital in Japan: an observational study

Purpose

Although many new patients are seen at small hospitals, there are few reports of new health problems from such hospitals in Japan. Therefore, we investigated the reasons for encounter (RFE) and diagnoses of new outpatients in a small hospital to provide educational resources for teaching general practice methods.

Methods

This observational study was conducted at the Department of General Internal Medicine in a small community hospital between May 6, 2010 and March 11, 2011. We classified RFEs and diagnoses according to component 1, “Symptoms/Complaints”, and component 7, “Diagnosis/Diseases”, of the International Classification of Primary Care, 2nd edition (ICPC-2). We also evaluated the differences between RFEs observed and common symptoms from the guidelines Model Core Curriculum for Medical Students and Goals of Clinical Clerkship.

Results

We analyzed the data of 1,515 outpatients. There were 2,252 RFEs (1.49 per encounter) and 170 ICPC-2 codes. The top 30 RFE codes accounted for 80% of all RFEs and the top 55 codes accounted for 90%. There were 1,727 diagnoses and 196 ICPC-2 codes. The top 50 diagnosis codes accounted for 80% of all diagnoses, and the top 90 codes accounted for 90%. Of the 2,252 RFEs, 1,408 (62.5%) included at least one of the 36 symptoms listed in the Model Core Curriculum and 1,443 (64.1%) included at least one of the 35 symptoms in the Goals of Clinical Clerkship. On the other hand, “A91 Abnormal result investigation”, “R21 Throat symptom/complaint”, and “R07 Sneezing/nasal congestion”, which were among the top 10 RFEs, were not included in these two guidelines.

Conclusion

We identified the common RFEs and diagnoses at a small hospital in Japan and revealed the inconsistencies between the RFEs observed and common symptoms listed in the guidelines. Our findings can be useful in improving the general practice medical education curricula.

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

Background

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.

Methods

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.

Results

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, <0.001). Component 1 had increased (P = 0.01), and component 2 had decreased (P = 0.04) in proportion.

Conclusion

Changes in population composition have brought a shift of the distribution of age in outpatients, more significantly in follow-up patients. Comparison by ICPC-2-E showed changes in RFEs of new patients between 2001 and 2008.

Morbidity patterns in general practice settings of the province of Sousse, Tunisia

BACKGROUND

Primary health care is one of the most important pillars of the Tunisian health care system. However, very little information is available regarding the specificities of general practice and the patterns of morbidity encountered.

METHODS

We conducted a descriptive study from June 2002 to May 2003 in 85 primary health centres in Sousse during 12 randomly selected weeks in order to describe the variability of the morbidity in all seasons; (3 weeks were randomly selected in each season). Each working day of selected weeks, a systematic sample of patients was identified in each health centre by taking every fifth registered patient. There were 16,271 consultations. The International Classification of Primary Care (ICPC-2) was used to code recorded data of the consultation.

RESULTS

There were 24,882 reasons for encounter, a total of 18,097 problems managed by general practitioners (GPs), and 40,190 interventions. There was a predominance of females (62%) and a relatively young population attending the primary health care settings as 50% was aged less than 25 years. According to ICPC-2 chapters, we found that respiratory diseases were the main problems managed in primary health care (43%), followed by digestive (10.1%), locomotive (8.9%), cardiovascular affections (8.7%) and skin diseases (8.4%). These five conditions alone constituted about 80% of the total cases. However, genital conditions for both males and females (1%) as well as psychological and social problems (0.85%) were rarely managed in primary care.

CONCLUSION

The findings will be useful in helping to revise the educational curriculum of medical studies as required in general practice and to plan relevant vocational training for GPs. They will also be important for health policy makers in Tunisia.
