Ontology highlight
ABSTRACT: Objectives
To determine the epidemiology of healthcare harm observable in general practice records.Design
Retrospective cohort records review study.Setting
72 general practice clinics were randomly selected from all 988 New Zealand clinics stratified by rurality and size; 44 clinics consented to participate.Participants
9076 patient records were randomly selected from participating clinics.Intervention
Eight general practitioners examined patient records (2011-2013) to identify harms, harm severity and preventability. Analyses were weighted to account for the stratified sampling design and generalise findings to all New Zealand patients.Main outcome measures
Healthcare harm, severity and preventability.Results
Reviewers identified 2972 harms affecting 1505 patients aged 0-102 years. Most patients (82.0%, weighted) experienced no harm. The estimated incidence of harm was 123 per 1000 patient-years. Most harms (2160; 72.7%, 72.4% weighted) were minor, 661 (22.2%, 22.8% weighted) were moderate, and 135 (4.5%, 4.4% weighted) severe. Eleven patients died, five following a preventable harm. Of the non-fatal harms, 2411 (81.6%, 79.4% weighted) were considered not preventable. Increasing age and number of consultations were associated with increased odds of harm. Compared with patients aged ≤49 years, patients aged 50-69 had an OR of 1.77 (95% CI 1.61 to 1.94), ≥70 years OR 3.23 (95% CI 2.37 to 4.41). Compared with patients with ≤3 consultations, patients with 4-12 consultations had an OR of 7.14 (95% CI 5.21 to 9.79); ≥13 consultations OR 30.06 (95% CI 21.70 to 41.63).Conclusions
Strategic balancing of healthcare risks and benefits may improve patient safety but will not necessarily eliminate harms, which often arise from standard care. Reducing harms considered 'not preventable' remains a laudable challenge.

Project description:BackgroundKnowing 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.ObjectiveWe 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.ResultsWe 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.ConclusionsThe 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:BackgroundDespite an overt commitment to equity, health inequities are evident throughout Aotearoa New Zealand. A general practice electronic alert system was developed to notify clinicians about their patient's risk of harm due to their pre-existing medical conditions or current medication. We aimed to determine whether there were any disparities in clinician action taken on the alert based on patient ethnicity or other demographic factors.MethodsSixty-six New Zealand general practices from throughout New Zealand participated. Data were available for 1611 alerts detected for 1582 patients between 1 and 2018 and 1 July 2019. The primary outcome was whether action was taken following an alert or not. Logistic regression was used to assess if patients of one ethnicity group were more or less likely to have action taken. Potential confounders considered in the analyses include patient age, gender, ethnicity, socio-economic deprivation, number of long term diagnoses and number of long term medications.ResultsNo evidence of a difference was found in the odds of having action taken amongst ethnicity groups, however the estimated odds for Māori and Pasifika patients were lower compared to the European group (Māori OR 0.88, 95 %CI 0.63-1.22; Pasifika OR 0.88, 95 %CI 0.52-1.49). Females had significantly lower odds of having action taken compared to males (OR 0.76, 95 %CI 0.59-0.96).ConclusionsThis analysis of data arising from a general practice electronic alert system in New Zealand found clinicians typically took action on those alerts. However, clinicians appear to take less action for women and Māori and Pasifika patients. Use of a targeted alert system has the potential to mitigate risk from medication-related harm. Recognising clinician biases may improve the equitability of health care provision.

Project description:BackgroundThe prevalence of CAM use is increasing. This integrative review investigated New Zealand healthcare professionals' practice of, attitudes toward, and knowledge about complementary and alternative medicine (CAM).MethodsLiterature search was conducted in four databases from inception to April 2020. Studies were included if they reported results from primary data collection on practice of, attitudes toward, or knowledge about CAM amongst New Zealand healthcare professionals.ResultsEleven studies (two of 'high-quality', seven of 'moderate-quality', and two of 'low-quality') were identified with 2060 healthcare professionals including general practitioners (GPs), nurses, midwives, pharmacists, physiotherapists, and medical specialists. New Zealand healthcare professionals were generally positive regarding CAM use, but have concerns on the scientific evidence, regulation, safety, financial costs of CAM, and encourage an evidence-based CAM practice and stronger CAM regulation. Findings indicated that around 25% of GPs practise CAM, and 82.3% refer patients to CAM practitioners. When treating pregnant women, 48.4% of physiotherapists practise acupuncture, and 37.3% of midwives recommend CAM. GPs believe that acupuncture is the most helpful CAM modality, and most commonly practiced and referred patients to acupuncture. Up to 58% of GPs and Plunket nurses wanted to receive further education on CAM, and up to 66.7% GPs favour the idea CAM should be included in medical curriculums.ConclusionsNine of the 11 included studies were of moderate to high quality, thus enhancing the reliability of the review findings. In order to better manage CAM in New Zealand New Zealand clinical settings, there is a need to invest in CAM research and education, and enhance CAM regulation. This review is a first step in developing an evidence base to offer insights for further development of effective CAM policies regarding safety, efficacy, regulation and integration in New Zealand.

Project description:BackgroundEstimating harm rates for specific patient populations and detecting significant changes in them over time are essential if patient safety in general practice is to be improved. Clinical record review (CRR) is arguably the most suitable method for these purposes, but the optimal values and combinations of its parameters (such as numbers of records and practices) remain unknown. Our aims were to: 1. Determine and quantify CRR parameters; 2. Assess the precision and power of feasible CRR scenarios; and 3. Quantify the minimum requirements for adequate precision and acceptable power.MethodWe explored precision and power of CRR scenarios using Monte Carlo simulation. A range of parameter values were combined in 864 different CRR scenarios, with 1000 random data sets generated for each, and harm rates were estimated and tested for change over time by fitting a generalised linear model with a Poisson response.ResultsCRR scenarios with ≥ 100 detected harm incidents had harm rate estimates with acceptable precision. Harm reductions of 20% or ≥ 50% were detected with adequate power by those CRR scenarios with at least 100 and 500 harm incidents respectively. The number of detected harm incidents was dependent on the baseline harm rate multiplied by: the period of time reviewed in each record; number of records reviewed per practice; number of practices who reviewed records; and the number of times each record was reviewed.ConclusionWe developed a simple formula to calculate the minimum values of CRR parameters required to achieve adequate precision and acceptable power when monitoring harm rates. Our findings have practical implications for health care decision-makers, leaders and researchers aiming to measure and reduce harm at regional or national level.

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:BackgroundClimate change is already affecting Aotearoa New Zealand (Aotearoa-NZ). The public health effects are varied and complex, and rural primary care staff will be at the front line of effects and responses. However, little is known about their understanding and experience.ObjectivesTo determine understanding, experiences and preparedness of rural general practice staff in Aotearoa-NZ about climate change and health equity.MethodsA mixed-methods national cross-sectional survey of rural general practice staff was undertaken that included Likert-style and free-text responses. Quantitative data were analysed with simple descriptive analysis and qualitative data were thematically analysed using a deductive framework based on Te Whare Tapa Whā.ResultsA proportion of survey respondents remained unsure about climate science and health links, although many others already reported a range of negative climate change health impacts on their communities, and expected these to worsen. Twenty to thirty percent of respondents lacked confidence in their health service's capability to provide support following extreme weather. Themes included acknowledgement that the health effects of climate change are highly varied and complex, that the health risks for rural communities combine climate change and wider environmental degradation and that climate change will exacerbate existing health inequities.ConclusionsThe study adds to sparse information on climate change effects on health in rural primary care. We suggest that tailored professional education on climate change science and rural health equity is still needed, while urgent resourcing and training for interagency disaster response within rural and remote communities is needed.

Project description:OBJECTIVE:To explore the perspectives of primary healthcare (PHC) professionals providing care to refugees through mainstream general practice. DESIGN:Qualitative exploratory design with semistructured interviews subjected to inductive thematic analysis. SETTING AND PARTICIPANTS:Nine general practices enrolled in the Dunedin Refugee Resettlement Programme, in New Zealand (NZ)'s southern health region. Participants included nine general practitioners and six practice nurses. RESULTS:Three analytical constructs were identified: relational engagement with refugees, refugee healthcare delivery and providers' professional role shaped by complexity. Building meaningful relational connections involved acknowledging refugees' journeys by getting to know them as people. This was instrumental for the development of an empathetic understanding of the complex human trajectories that characterise refugees' journeys to NZ. Participants encountered challenges in providing care to refugees with respect to time-limited consultations, variable use of interpreter services, fragmentation of care between agencies and need for improved health infrastructure to ensure a fluid interface between PHC, secondary care and community support services. The current business model of NZ general practice was perceived to interfere with value-driven care and discouraged tailoring of care to specific patient groups, raising concerns about the 'fit' of mainstream general practice to address the complex healthcare needs of refugees. Meeting the needs of refugees across the social determinants of health involved a lot of 'behind the scenes work' particularly in the absence of shared information systems and the lack of well-established referral pathways to connect refugees to services beyond the health sector. This led to providers feeling overwhelmed and uncertain about their ability to provide appropriate care to refugees. CONCLUSIONS:This study provides rich context-specific findings that enhance PHC responsiveness to the needs of refugees in NZ.

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.

Project description:Current descriptions add natives Aporodrilus aoteasp. n., Aporodrilus pongasp. n. and Notoscolex repangasp. n., plus new exotic records to the numbers of megadrile earthworms known from New Zealand, which are now raised from 193 to 222 species in five families, viz: Acanthodrilidae, Octochaetidae and Megascolecidae, plus Lumbricidae and Glossoscolecidae for exotics. Overlooked spermathecal diverticula have been located for Notoscolex equestris Benham, 1942 and for Megascolex animae Lee, 1959 and non-tubular prostrates were misconstrued as tubular in Megascolides tasmani Lee, 1959. Of these latter three species, a lectotype is designated for Notoscolex equestris and holotypes of the other two are briefly redescribed. Whereas Megascolides tasmani now belongs in Notoscolex Fletcher, 1887 and Megascolides animae belongs in Anisochaeta Beddard, 1890, further lack of dorsal pores in Notoscolex equestris as with Notoscolex esculentus (Benham, 1904) and Notoscolex mortenseni (Michaelsen, 1924) newly qualifies all three as additional combs. novae in primarily Tasmanian genus Aporodrilus Blakemore, 2000.
