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.

Daytime contacts and general practitioner consultations, and pain as a reason for encounter in children with cerebral palsy; a Norwegian national registry linkage study

AIM

The aim of this study was to compare the prevalence of daytime contacts and consultations, and pain as a reason for encounter (RFE) with a general practitioner (GP), in children with cerebral palsy (CP) (cases) to that of the general paediatric population (controls).

METHODS

The study linked the Norwegian Directorate of Health's database for the control and reimbursement of health expenses, and the Norwegian Quality and Surveillance Registry for Cerebral Palsy, including children born from 1996 to 2012 in the period 2006 to 2018. All daytime contacts were included. International Classification for Primary Care was applied for RFE.

RESULTS

Cases accounted for 0.46% of all daytime contacts and 0.27% of all daytime consultations, the latter corresponding with the estimated national prevalence of CP. GPs registered more administrative contact and coded pain as an RFE less frequently in consultations with cases (6%) than with controls (12%).

INTERPRETATION

Children with CP did not consult GPs more than the general paediatric population did. In consultations, GPs should ask for pain even if the child with CP or parent does not address pain. The local multidisciplinary team should encourage the family to consider consulting a GP if the child is in pain.KEY MESSAGESPrevalence of GP consultations in children with CP is similar to that of children in the general population.GPs perform more administrative work for children with CP than for their other paediatric patients.GPs code pain as an RFE less frequently in consultations with children with CP than in consultations with children in the general population.

Antibiotic Prescribing and Doctor-Patient Communication During Consultations for Respiratory Tract Infections: A Video Observation Study in Out-of-Hours Primary Care

Objective: Communication skills can reduce inappropriate antibiotic prescribing, which could help to tackle antibiotic resistance. General practitioners often overestimate patient expectations for an antibiotic. In this study, we describe how general practitioners and patients with respiratory tract infections (RTI) communicate about their problem, including the reason for encounter and ideas, concerns, and expectations (ICE), and how this relates to (non-)antibiotic prescribing in out-of-hours (OOH) primary care.

Methods: A qualitative descriptive framework analysis of video-recorded consultations during OOH primary care focusing on doctor-patient communication.

Results: We analyzed 77 videos from 19 general practitioners. General practitioners using patient-centered communication skills received more information on the perspective of the patients on the illness period. For some patients, the reason for the encounter was motivated by their belief that a general practitioner (GP) visit will alter the course of their illness. The ideas, concerns, and expectations often remained implicit, but the concerns were expressed by the choice of words, tone of voice, repetition of words, etc. Delayed prescribing was sometimes used to respond to implicit patient expectations for an antibiotic. Patients accepted a non-antibiotic management plan well.

Conclusion: Not addressing the ICE of patients, or their reason to consult the GP OOH, could drive assumptions about patient expectations for antibiotics early on and antibiotic prescribing later in the consultation.

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.

Primary health care for people with an intellectual disability: an exploration of demographic characteristics and reasons for encounters from the BEACH programme

BACKGROUND

People with an intellectual disability (ID) have complex and different patterns of healthcare needs. Poor participation in primary health care contributes to the high levels of undetected and unmanaged health issues and premature deaths of people with an ID. Limited research is available on the characteristics of people with an ID, their reasons for consulting general practitioners (GPs), and if these differ to people without an ID. Gaining such insights may provide an avenue to better understand patterns of primary care use and potential gaps in usage by people with an ID given their complex health profile compared with people without an ID.

METHOD

A secondary analysis of data collected January 2003 to December 2012 from The Bettering the Evaluation and Care of Health programme was used. Participant characteristics and their reasons for encounter, pre- and post-age-sex standardisation, at all GP encounters with people identified in the encounter record as having an ID ('ID' encounters, n = 690) were compared with those at 'non-ID' encounters (n = 970 641). Statistical significance was tested with chi-squared statistics or 95% confidence intervals as appropriate.

RESULTS

This study identified significant differences in participant characteristics and their reasons for consulting GPs at ID encounters compared with non-ID encounters. Participants at ID encounters had a skewed demography, an over-representation of presentations for psychological, social and 'general and unspecified' reasons, and an under-representation of presentations for core physical health and preventive health measures. Administrative rather than medically related reasons dominated presentations to general practice at ID encounters.

CONCLUSION

There are significant differences in the characteristics of participants and their reasons for presentation to general practice in Australia for participants at ID encounters compared with non-ID encounters. This work suggests that there is a difference in service use patterns between these two groups. These findings may suggest that people with an ID experience barriers to participating in essential primary healthcare services.

Out-of-hours primary care: a population-based study of the diagnostic scope of telephone contacts

BACKGROUND

GPs answer all patient calls to the out-of-hours primary care (OOH-PC) services in Denmark. Knowledge is scarce on how the triage-GPs act on the specific reasons for encounter (RFE).

OBJECTIVE

This study aims to describe the RFEs, the applied diagnoses and the severity of health problems presented in calls to the OOH-PC.

METHODS

This was a 1-year cross-sectional study based on IT-integrated pop-up questionnaires addressing patients' health problems. We included only telephone contacts that were categorized according to their triage outcome as telephone consultations, direct admissions to hospital or referrals for face-to-face contact. The GP-assessed severity was calculated for age groups and types of outcome. We identified the 20 most frequent primary RFEs and diagnoses for each type of contact termination.

RESULTS

We included 7810 telephone calls. Calls considered non-severe made up two-thirds of the calls terminated as telephone consultations, whereas calls considered potentially severe made up the main part of referrals (52.3%). Overall, the 20 most frequent RFEs accounted for 45.2% of all RFEs, fever being the most frequent (10.0%). Some RFEs were terminated mostly as telephone consultations [e.g. insect bite/sting (75.9%)], whereas others were most often referred for a face-to-face contact [i.e. dyspnoea (79.1%)] or directly to hospital [i.e. chest pain (29.4%)].

CONCLUSION

The distribution of the RFEs on triage outcomes, dominated by more severe diagnoses in referrals indicates a suitable referral level. However, future research on factors related to the demanding task of telephone triage is highly relevant for postdoctoral training of GPs.

Chest pain in general practice: Frequency, management, and results of encounter

Objective:

Chest pain is a common reason for an encounter in general practice. The present investigation was set out to characterize the consultation rate of chest pain, accompanying symptoms, frequency of diagnostic and therapeutic interventions, and results of the encounter.

Materials and Methods:

Cross-sectional data were collected from randomly selected patients in the German Sächsische Epidemiologische Studie in der Allgemeinmedizin 2 (SESAM 2) and analyzed from the Dutch Transition Project.

Results:

Overall, 270 patients from the SESAM 2 study consulted a general practitioner due to chest pain (3% of all consultations). Chest pain was more frequent in people aged over 45 years. The most common diagnostic interventions were physical examination, electrocardiogram at rest and analysis of blood parameters. For the majority of cases, the physicians arranged a follow-up consultation or prescribed drugs. The transition project documented 8117 patients reporting chest pain with a frequency of 44.5/1000 patient years (1.7% of all consultations). Physical examination was also the most common diagnostic intervention, and physician's advice the most relevant therapeutic one.

Conclusion:

The most common causes for chest pain were musculoskeletal problems followed by cardiovascular diseases. Ischemic heart disease, psychogenic problems, and respiratory diseases each account for about 10% of the cases. However, acutely dangerous causes are rare in general practice.

Evidence-based rules from family practice to inform family practice; the learning healthcare system case study on urinary tract infections

BACKGROUND

Analysis of encounter data relevant to the diagnostic process sourced from routine electronic medical record (EMR) databases represents a classic example of the concept of a learning healthcare system (LHS). By collecting International Classification of Primary Care (ICPC) coded EMR data as part of the Transition Project from Dutch and Maltese databases (using the EMR TransHIS), data mining algorithms can empirically quantify the relationships of all presenting reasons for encounter (RfEs) and recorded diagnostic outcomes. We have specifically looked at new episodes of care (EoC) for two urinary system infections: simple urinary tract infection (UTI, ICPC code: U71) and pyelonephritis (ICPC code: U70).

METHODS

Participating family doctors (FDs) recorded details of all their patient contacts in an EoC structure using the ICPC, including RfEs presented by the patient, and the FDs' diagnostic labels. The relationships between RfEs and episode titles were studied using probabilistic and data mining methods as part of the TRANSFoRm project.

RESULTS

The Dutch data indicated that the presence of RfE's "Cystitis/Urinary Tract Infection", "Dysuria", "Fear of UTI", "Urinary frequency/urgency", "Haematuria", "Urine symptom/complaint, other" are all strong, reliable, predictors for the diagnosis "Cystitis/Urinary Tract Infection" . The Maltese data indicated that the presence of RfE's "Dysuria", "Urinary frequency/urgency", "Haematuria" are all strong, reliable, predictors for the diagnosis "Cystitis/Urinary Tract Infection". The Dutch data indicated that the presence of RfE's "Flank/axilla symptom/complaint", "Dysuria", "Fever", "Cystitis/Urinary Tract Infection", "Abdominal pain/cramps general" are all strong, reliable, predictors for the diagnosis "Pyelonephritis" . The Maltese data set did not present any clinically and statistically significant predictors for pyelonephritis.

CONCLUSIONS

We describe clinically and statistically significant diagnostic associations observed between UTIs and pyelonephritis presenting as a new problem in family practice, and all associated RfEs, and demonstrate that the significant diagnostic cues obtained are consistent with the literature. We conclude that it is possible to generate clinically meaningful diagnostic evidence from electronic sources of patient data.

International classification of primary care: an Indian experience

Background:

India is in the process of transition to universal health coverage for Indian citizens. The focus is to strengthen the primary and secondary level services. Coupled with this national scenario, the development of Family medicine as a distinct discipline is in a crucial stage. There is a nation-wide urge to build family medicine training units and service centers across the country to fulfill the unmet health needs of the population.

Objectives:

This study aimed to bring out reasons for encounter (RFE) and morbidity pattern of patients seen in a family physician run urban health center in South India.

Methods:

The study was conducted in an urban health center of a tertiary care hospital. Clinicians entered the data using International Classification of Primary Care (ICPC) codes. Data included were demographics, 3 RFE, 3 diagnoses, 3 outcomes of care that include prescriptions, investigations, procedures, and referrals made.

Results:

During 47,590 patient encounters, 59,647 RFE, 62,283 diagnoses and 68269 outcomes of care were recorded. The majority of RFEs and diagnoses are in the following ICPC chapters: Endocrinology (38.6%), cardiovascular (35.91%), respiratory (20.26%), digestive (7.68% and musculo-skeletal (6.8%). The most frequent outcome of care was prescriptions, followed by counseling and nebulization.

Conclusion:

This study is the first to report on the RFE in India. This study demonstrated the breadth of clinical conditions seen by family physicians across all ages and in both genders. This study attempts to highlight the need for family physician based services as a training ground for trainees.
