Medication-related harm in New Zealand general practice: a retrospective records review.

BACKGROUND: The extent of medication-related harm in general practice is unknown. AIM: To identify and describe all medication-related harm in electronic general practice records. The secondary aim was to investigate factors potentially associated with medication-related harm. DESIGN AND SETTING: Retrospective cohort records review study in 44 randomly selected New Zealand general practices for the 3 years 2011-2013. METHOD: Eight GPs reviewed 9076 randomly selected patient records. Medication-related harms were identified when the causal agent was prescribed in general practice. Harms were coded by type, preventability, and severity. The number and proportion of patients who experienced medication-related harm was calculated. Weighted logistic regression was used to identify factors associated with harm. RESULTS: In total, 976 of 9076 patients (10.8%) experienced 1762 medication-related harms over 3 years. After weighting, the incidence rate of all medication-related harms was 73.9 harms per 1000 patient-years, and the incidence of preventable, or potentially preventable, medication-related harms was 15.6 per 1000 patient-years. Most harms were minor (n = 1385/1762, 78.6%), but around one in five harms were moderate or severe (n = 373/1762, 21.2%); three patients died. Eighteen study patients were hospitalised; after weighting this correlates to a hospitalisation rate of 1.1 per 1000 patient-years. Increased age, number of consultations, and number of medications were associated with increased risk of medication-related harm. Cardiovascular medications, antineoplastic and immunomodulatory agents, and anticoagulants caused most harm by frequency and severity. CONCLUSION: Medication-related harm in general practice is common. This study adds to the evidence about the risk posed by medication in the real world. Findings can be used to inform decision making in general practice.

Characteristics of a stratified random sample of New Zealand general practices.

INTRODUCTION Practice size and location may affect the quality and safety of health care. Little is known about contemporary New Zealand general practice characteristics in terms of staffing, ownership and services. AIM To describe and compare the characteristics of small, medium and large general practices in rural and urban New Zealand. METHODS Seventy-two general practices were randomly selected from the 2014 Primary Health Organisation database and invited to participate in a records review study. Forty-five recruited practices located throughout New Zealand provided data on staff, health-care services and practice ownership. Chi-square and other non-parametric statistical analyses were used to compare practices. RESULTS The 45 study practices constituted 4.6% of New Zealand practices. Rural practices were located further from the nearest regional base hospital (rural median 65.0 km, urban 7.5 km (P < 0.001)), nearest local hospital (rural 25.7 km, urban 7.0 km (P = 0.002)) and nearest neighbouring general practitioner (GP) (rural 16.0 km, urban 1.0 km (P = 0.007)). In large practices, there were more enrolled patients per GP FTE than both medium-sized and small practices (mean 1827 compared to 1457 and 1120 respectively, P = 0.019). Nurses in large practices were more likely to insert intravenous lines (P = 0.026) and take blood (P = 0.049). There were no significant differences in practice ownership arrangements according to practice size or rurality. CONCLUSION Study practices were relatively homogenous. Unsurprisingly, rural practices were further away from hospitals. Larger practices had higher patient-to-doctor ratios and increased nursing scope. The study sample is small; findings need to be confirmed by specifically powered research.

Research using electronic health records: Balancing confidentiality and public good.

General practitioners are increasingly approached to participate in research and share de-identified patient information. Research using electronic health records has considerable potential for improving the quality and safety of patient care. Obtaining individual patient consent for the use of the information is usually not feasible. In this article we explore the ethical issues in using personal health information in research without patient consent including the threat to confidentially and the doctor-patient relationship, and we discuss how the risks can be minimised and managed drawing on our experience as general practitioners and researchers.

Epidemiology of Patient Harms in New Zealand: Protocol of a General Practice Records Review Study.

BACKGROUND: Knowing where and why harm occurs in general practice will assist patients, doctors, and others in making informed decisions about the risks and benefits of treatment options. Research to date has been unable to verify the safety of primary health care and epidemiological research about patient harms in general practice is now a top priority for advancing health systems safety. OBJECTIVE: We aim to study the incidence, distribution, severity, and preventability of the harms patients experience due to their health care, from the whole-of-health-system lens afforded by electronic general practice patient records. METHODS: "Harm" is defined as disease, injury, disability, suffering, and death, arising from the health system. The study design is a stratified, 2-level cluster, retrospective records review study. Both general practices and patients will be randomly selected so that the study's results will apply nationally, after weighting. Stratification by practice size and rurality will allow comparisons between 6 study groups (large, medium-sized, small; urban and rural practices). Records of equal numbers of patients from each study group will be included in the study because there may be systematic differences in patient harms in different types of practices. Eight general practitioner investigators will review 3 years of electronic general practice health records (consultation notes, prescriptions, investigations, referrals, and summaries of hospital care) from 9000 patients registered in 60 general practices. Double-blinded reviews will check the concordance of reviewers' assessments. Study data will comprise demographic data of all 9000 patients and reviewers' assessments of whether patients experienced harm arising from health care. Where patient harm is identified, their types, preventability, severity, and outcomes will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) 18.0. RESULTS: We have recruited practices and collected electronic records from 9078 patients. Reviews of these records are under way. The study is expected to be completed in August 2017. CONCLUSIONS: The design of this complex study is presented with discussion on data collection methods, sampling weights, power analysis, and statistical approach. This study will show the epidemiology of patient harms recorded in general practice records for all of New Zealand and will show whether this epidemiology differs by rural location and clinic size.

Educating vocationally trained family physicians: a survey of graduates from a postgraduate medical education programme.

INTRODUCTION Since 1991 the University of Otago, Dunedin, New Zealand has offered postgraduate qualifications specifically designed to educate general practitioners (GPs) about their unique work environment. AIM To determine motivations and impacts of postgraduate education for practising GPs. METHODS Survey of the 100 graduates of the University of Otago, Dunedin postgraduate general practice programme. Ninety five living graduates were approached and 70 (73.7%) responded. Quantitative data about disposition of respondents before enrolling and after completion of the programme were analysed using chi-square and paired t-tests. Free text responses about motivations, impacts and outcomes of the program were thematically analysed. RESULTS 64 GPs graduated with a postgraduate diploma and 36 with a masters degree in general practice. Although the mean number of graduates was 3.5 and 2.0 (respectively), annual enrolments averaged 25.1. Most graduates (60.9%) were aged in their 40s when they started studying and most (94.3%) had a spouse and/or children at home. DISCUSSION This voluntary postgraduate medical education complements traditional medical training but has low external value despite personal, practising and professional benefits. Graduates valued engagement above completion of a qualification. KEYWORDS Medical education; general practitioners; scholarship; professionalism.
