The reliability and validity of doctor-recorded morbidity data in active data collection systems.

OBJECTIVE: To test the reliability and validity of morbidity data recorded by general practitioners (family physicians) on structured recording forms in active data collection systems. DESIGN: The consulting general practitioner recorded the problems managed at 347 video-taped doctor-patient contacts. Two observers independently viewed the video-tapes and completed a recording form for each. Problems were centrally coded, using the International Classification of Primary Care (ICPC). SETTING: Primary health care. MAIN OUTCOME MEASURES: Overall distribution of the morbidity; positive agreement regarding the morbidity managed at matched contacts at three levels of specificity (chapter; chapter-component; specific rubric); agreement taking negative agreement into account using Cohen's Kappa. RESULTS: Overall distribution of morbidity did not differ between observers. Positive mean agreement was 78.8% at chapter level, 69.6% at chapter-component, and 55.9% at rubric level. Kappa statistics showed agreement better than chance in all chapters, but failed to reach significance at rubric level in three chapters. CONCLUSION: Morbidity data actively collected by GPs provide a reliable overview of morbidity managed in general practice. At a specific contact the morbidity recorded is reliable and valid at chapter level, and in most cases, at chapter-component level. At rubric level variance between practitioners in labelling the problem calls into question the validity and reliability of the data.

Sex differences in prescribed medications: another case of discrimination in general practice.

Biological, social and behavioural factors influence doctors to prescribe different types of medications to male and female patients. Secondary analysis of data from the Australian Morbidity and Treatment Survey 1990-1991 was conducted using multiple logistic regression to discriminate male and female patient encounters in general practice. The approach used considered possible confounding influences of GP and patient characteristics. The results showed that females were significantly more likely than males to receive prescriptions for: antibiotics; hormones; drugs affecting the central nervous, cardiovascular and urogenital systems; drugs for allergy and immune disorders; ear and nose topical preparations, and skin preparations, even after taking into account morbidity differences. If males and females were treated according to their presenting problems, differences in morbidity patterns would account for the management differences. However, the present investigation would suggest that GP and patient behaviours are also important factors that lead to differences in the prescriptions received by male and female patients in general practice.

Collecting data on potentially harmful events: a method for monitoring incidents in general practice.

OBJECTIVE: The prediction and subsequent prevention of errors, which are an integral element of human behaviour, require an understanding of their cause. The incident monitoring technique was developed in the study of aviation errors in the Second World War and has been applied more recently in the field of anaesthetics. This pilot study represents one of the first attempts to apply the incident monitoring technique in the general practice environment. METHOD: A total of 297 GPs across Australia anonymously reported details of unintended events which harmed or could have harmed the patient. Reports were contemporaneously recorded on prepared forms which allowed a free text description of the incident, and structured responses for contributing and mitigating factors, immediate and long-term out-comes, additional costs etc. RESULTS AND DISCUSSION: The first 500 reports were analysed using both of qualitative and quantitative methods and a brief overview of results is presented. The methodological issues arising in the application of this technique to such a large, widely spread profession, in which episodes of care are not necessarily confined to a single consultation, are discussed. This study demonstrated that the incident monitoring technique can be successfully applied in general practice and that the resulting information can facilitate the identification of common factors contributing to such events and allow the development of preventive interventions.

A new coding tool for computerised clinical systems in primary care--ICPC plus.

Standardised classifications are essential for reliable information management. The International Classification of Primary Care (ICPC) provides a recognised structure for classifying problems managed in general practice but lacks sufficient details for medical records. This paper describes an extended version of ICPC, based on the natural language of GPs in Australia, for use in computerised clinical systems.

Sex differences in morbidity: a case of discrimination in general practice.

Several factors influence sex differences in morbidity and general practice utilization rates. These factors are of a biological, social and behavioural nature and have differential effects on varying morbidity types. Secondary analysis of data from the Australian Morbidity and Treatment Survey 1990-91, was conducted using multiple logistic regression to discriminate female from male patient encounters in general practice. This approach considered possible confounding influences of GP and patient characteristics. The results showed there was a tendency for larger differences in the types of problems managed than in the types of reasons for encounter presented. Morbidity related to the reproductive, genitourinary and neurological systems, the blood, and of a psychological and social nature were significant contributors to female poor health and service utilization. Females were also more likely to present with digestive, cardiovascular and respiratory problems, while males were more likely to have digestive and cardiovascular problems managed. Furthermore, males were more likely to present skin complaints and have them managed. The potentially higher rates for males in cardiovascular, digestive, skin and respiratory morbidity not only reflect biological differences, but suggest differences in health reporting, utilisation and illness preventive attitudes.

Methodology of morbidity and treatment data collection in general practice in Australia: a comparison of two methods.

OBJECTIVES: To compare two methods of data collection of patient-practitioner encounter data in general practice: from medical records consultation notes and from data recorded on encounter forms. METHOD: Data were collected from two sources: (i) Medical Records Study: a study of the efficacy of an intervention designed to improve the quality of medical records provided details of 3107 patient encounters with 163 general practitioners (GPs) which had been photocopied from medical records; and (ii) Australian Morbidity and Treatment Survey (AMTS): from a national sample of 495 GPs and over 100,000 patient encounters, data from 47 GPs in the same geographical area as those in the Medical Records Study provided encounter forms for 10,392 patient encounters including details about patient demographics, reason for encounter, management, treatment, tests and investigations, admissions, referrals and planned follow-up. The International Classification of Primary Care (ICPC) was used to code reasons for encounter and problems managed. Drugs were classified according to an in-house classification by generic name and broad drug group. RESULTS: Patient details and all items of clinical information were recorded less frequently or were more often illegible in medical records than on encounter forms. There was a higher rate of management of problems classified as general or non-specific in the medical records. A lower prescribing rate for drugs acting on the cardiovascular system was recorded in the medical records, but higher rates were found for antibiotics, drugs acting on the immune system and miscellaneous drugs. Coding of all data was more reliable both between and within coders using the data from the encounter forms compared to the medical records. CONCLUSION: General practice data obtained from encounter forms are more comprehensive and are coded more reliably than those drawn from medical records.

General practice receptionists' attitudes and beliefs towards preventive medicine before and after training and support interventions.

OBJECTIVES: Receptionists are an integral part of the primary care service. We aimed to discover their views on preventive medicine issues. METHOD: One hundred and fifty receptionists from general practices in Sydney, Australia, completed a questionnaire on their attitudes and beliefs towards preventive medicine and brief intervention for alcohol. They were matched according to practice variables into a control, no, minimal, or maximal training and support condition. In all conditions except the control condition, receptionists received 5 minutes of initial training in implementing a brief intervention programme; the amount of ongoing support varied across conditions. Attitudes and beliefs were re-assessed 3 months later. RESULTS AND CONCLUSIONS: The results indicated that when no training and support were given, receptionists developed negative views towards being involved in preventive medicine activities. When training and support were provided, these negative effects were abolished.

The sex of the general practitioner: a comparison of characteristics, patients, and medical conditions managed.

In Australia an increasing proportion of active general practitioners (GPs) are women. Overseas research showing differences between male and female GPs in practice style, the reasons patients consult them, or in the nature of the medical conditions they manage has failed to adjust for confounders. In Australia, such differences have never been investigated. This study assessed differences between male and female GPs in terms of their personal characteristics, patient mix, patient reasons for consultation, and the medical conditions they manage. It also considered the extent to which differences are accounted for by the effect of confounders. A secondary analysis was done of data from the Australian Morbidity and Treatment Survey 1990 to 1991 (n = 113,000 general practice encounters). In addition, univariate analysis was followed by multivariate analysis, with adjustments for GP and patient characteristics and (in analysis of conditions managed) for patient reasons for encounter. Significant differences were found in the work patterns and patient mix of male and female GPs. Patients' selectivity in the problems presented to the two groups remained after adjustment for confounders. Female GPs managed more female-specific, endocrine, general, and psychosocial problems even after multivariate adjustment. Although male GPs managed more cardiovascular, musculoskeletal, male genital, skin, and respiratory problems at the univariate level, these differences were no longer apparent after adjustment. Male and female GPs manage different types of medical conditions. Although some differences are due to their patient mix and to patient selectivity, others are inherent to the sex of the physician. Extrapolation of results to Australian general practice suggests that these two groups of GPs could become semispecialized.

An analysis of age and gender influences on the relative risk for suicide and psychotropic drug self-poisoning.

Psychiatric illness is a significant risk factor for both attempted and completed suicide and psychotropic medications account for 80% of all drug overdoses involving prescription medications. One challenge facing clinicians is to balance the benefit of treatment against the risk of drug overdose. The aim of the present study was to compare the age and gender distribution of patients prescribed psychotropic drugs with patients attempting and completing suicide with these drugs. Data were obtained from the Australian census and studies of general practitioner prescribing, patients who committed suicide or presented with self-poisoning within a defined geographic area. The characteristics of these populations were compared to calculate odds ratios for attempting or completing suicide with psychotropic drugs, before and after correction for rates of prescription, in different age and gender groups. The odds ratios (ORs) for self-poisoning were higher for those aged less than 45 years and yet this group was least likely to be prescribed psychotropic drugs. Men had a much higher rate of completed suicide using more lethal methods. The ORs for self-poisoning and suicide with psychotropic drugs, after correction for prescription rates, for those aged 15 to 24 years were 11.1 and 1.7, respectively. Those aged 25 to 44 years had ORs of 4.9 and 4.3, and, by contrast, those over 75 years had ORs of 0.03 and 0. Women were slightly more likely to poison themselves with psychotropic drugs (OR 1.2). However, the situation reversed after correction for prescription rates (OR 0.69). It is concluded that greater caution should be exercised in prescribing for those under 45 years of age, given their relatively higher risk of drug overdose, and that the least toxic compounds should be used. The risk (of self-poisoning) among the elderly may have been overstated, so that some patients may have been denied the benefit of adequate treatment.

Tests and investigations. Indicators for better utilisation.

Diagnostic tests and investigations are standard tools for today's general practitioner. However, without reliable systems for the management of tests and test results, these valuable assets may become a liability to the GP, with the possibility of unforeseen adverse events arising at several points in the total investigative process. Exploring GPs' reports of such incidents may provide opportunities for improvements in patient care.
