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

ABSTRACT:

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.

Project description:ObjectiveLittle is known about differences in hospital harm (injury, suffering, disability, disease or death arising from hospital care) when people from rural and urban locations require hospital care. This study aimed to assess whether hospital harm risk differed by patients' rural or urban location using general practice data.DesignSecondary analysis of a 3-year retrospective cross-sectional general practice records review study, designed with equal numbers of rural and urban patients and patients from small, medium and large practices. Hospital admissions, interhospital transfer and hospital harm were identified.SettingNew Zealand (NZ) general practice clinical records including hospital discharge data.ParticipantsRandomly selected patient records from randomly selected general practices across NZ. Patient enrolment at rural and urban general practices defined patient location.OutcomesAdmission and harm risk and rate ratios by rural-urban location were investigated using multivariable analyses adjusted for age, sex, ethnicity, deprivation, practice size. Preventable hospital harm, harm severity and harm associated with interhospital transfer were analysed.ResultsOf 9076 patient records, 1561 patients (17%) experienced hospital admissions with no significant association between patient location and hospital admission (rural vs urban adjusted risk ratio (aRR) 0.98 (95% CI 0.83 to 1.17)). Of patients admitted to hospital, 172 (11%) experienced hospital harm. Rural location was not associated with increased hospital harm risk (aRR 1.01 (95% CI 0.97 to 1.05)) or rate of hospital harm per admission (adjusted incidence rate ratio 1.09 (95% CI 0.83 to 1.43)). Nearly half (45%) of hospital harms became apparent only after discharge. No urban patients required interhospital transfer, but 3% of rural patients did. Interhospital transfer was associated with over twice the risk of hospital harm (age-adjusted aRR 2.33 (95% CI 1.37 to 3.98), p=0.003).ConclusionsRural patient location was not associated with increased hospital harm. This provides reassurance for rural communities and health planners. The exception was patients needing interhospital transfer, where risk was more than doubled, warranting further research.

Project description:ObjectivesLittle is known about the quality of clinical care provided outside the hospital sector, despite the increasingly important role of clinical generalists working in primary care. In this study we aimed to summarise published evaluations of the quality of clinical care provided in general practice in the UK, Australia, and New Zealand.DesignA systematic review of published studies assessing the quality of clinical care in general practice for the period 1995-9.SettingGeneral practice based care in the UK, Australia, and New Zealand. Main outcome measures-Study design, sampling strategy and size, clinical conditions studied, quality of care attained for each condition (compared with explicit or implicit standards for the process of care), and country of origin for each study.ResultsNinety papers fulfilled the entry criteria for the review, 80 from the UK, six from Australia, and four from New Zealand. Two thirds of the studies assessed care in self-selected practices and 20% of the studies were based in single practices. The majority (85.5%) examined the quality of care provided for chronic conditions including cardiovascular disease (22%), hypertension (14%), diabetes (14%), and asthma (13%). A further 12% and 2% examined preventive care and acute conditions, respectively. In almost all studies the processes of care did not attain the standards set out in national guidelines or those set by the researchers themselves. For example, in the highest achieving practices 49% of diabetic patients had had their fundii examined in the previous year and 47% of eligible patients had been prescribed beta blockers after an acute myocardial infarction.ConclusionsThis study adopts an overview of the magnitude and the nature of clinical quality problems in general practice in three countries. Most of the studies in the systematic review come from the UK and the small number of papers from Australia and New Zealand make it more difficult to draw conclusions about the quality of care in these two countries. The review helps to identify deficiencies in the research, clinical and policy agendas in a part of the health care system where quality of care has been largely ignored to date. Further work is required to evaluate the quality of clinical care in a representative sample of the population, to identify the reasons for substandard care, and to test strategies to improve the clinical care provided in general practice.

Project description:BackgroundMedicines are central to healthcare in aging populations with chronic multi-morbidity. Their safe and effective use relies on a large and constantly increasing knowledge base. Despite the current era of unprecedented access to information, there is evidence that unmet information needs remain an issue in clinical practice. Unmet medicines information needs may contribute to sub-optimal use of medicines and patient harm. Little is known about medicines information needs in the primary care setting. The aim of this study was to investigate the nature of medicines information needs in routine general practice and understand the challenges and influences on the information-seeking behaviour of general practitioners.MethodsA mixed methods study involving 18 New Zealand general practitioner participants was undertaken. Quantitative data were collected to characterize the medicines information needs arising during 642 consultations conducted by the participants. Qualitative data regarding participant views on their medicines information needs, resources used, challenges to meeting the needs and potential solutions were collected by semi-structured interview. Integration occurred by comparison of results from each method.ResultsOf 642 consultations, 11% (n = 73/642) featured at least one medicines information need. The needs spanned 14 different categories with dosing the most frequent (26%) followed by side effects (15%) and drug interactions (14%). Two main themes describing the nature of general practitioners' medicines information needs were identified from the qualitative data: a 'common core' related to medicine dose, side effects and interactions and a 'perplexing periphery'. Challenges in the perplexing periphery were the variation in information needs, complexity, 'known unknowns' and 'unknown unknowns'. Key factors affecting general practitioners' strategies for meeting medicines information needs were trust in a resource, presence of the patient, how the information was presented, scarcity of time, awareness of the existence of a resource, and its accessibility.ConclusionsGeneral practitioners face challenges in meeting wide-ranging medicines information needs in patients with increasingly complex care needs. Recognising the challenges and factors that influence resource use in practice can inform optimisation of medicines information support resources. Resources for general practitioners must take into account the complexity and time constraints of real-world practice. An individually responsive approach involving greater collaboration with pharmacists and specialist medicines information support services may provide a potential solution.
