Telehealth Uptake and Impact on Care Activities in Australian General Practice During the COVID-19 Pandemic

The COVID-19 pandemic necessitated a shift in the delivery of patient care, with telehealth rapidly scaled to facilitate access to care while reducing risks of COVID-19 transmission. In this paper, we present an overview of key findings regarding telehealth use from a large program of work examining the impact of the pandemic on general practice activity in Australia. Our findings demonstrate the pivotal role telehealth played in enabling patient access to care during the first two years of the pandemic. Importantly, however, we identified several facets of telehealth use including equitable access, workflow and infrastructure, and adequate funding, which require attention to optimise telehealth services in practice.

Quality of life in parents of Turkish and Syrian pediatric bone marrow transplant and oncology patients

Background

The success of the treatment depends on the well-being of the parents in pediatric cancer patients. In addition, migrants need to deal with the consequences of war.

Aim

Our purpose was to compare the HRQoL of parents of Syrian and Turkish children followed in our bone marrow transplant and oncology units.

Materials and Methods

One hundred SF 36 questionnaires, fifty from each group were collected between October 2019 and March 2020 in this cross-sectional study. Demographic characteristics of the patients (sex, age, cancer type, presence of relapse, duration of follow-up) and education level of parents were recorded. Analyses were performed using IBM SPSS Statistics version 20.0.

Results

Turkish parents reported better results in physical functioning, emotional well-being, physical pain, general health, and physical health composite score (P < 0.05). There were more fathers in the Syrian group and education status was significant between the two groups (P = 0.01, P = 0.001, respectively). There was no correlation between QoL and education levels in the Turkish group. In Syrian parents, pain score was high in middle school graduates (P = 0.043). In the presence of relapse, although the physical function score decreased, the physical role function score increased in Turkish parents (P = 0.0035, P = 0.005, respectively). Syrian parents' emotional role function and energy/fatigue score were both increased when children had relapses (P = 0.027for both).

Conclusion

Migration is a complex issue. Turkish parents were better in physical functioning, emotional well-being, physical pain, general health, and physical health composite score. Screening for parental burden, assisting them to find appropriate support services is essential in improving the health and QoL of both our patients and their parents.

Vitamin D testing in children and adolescents in Victoria, Australia: are testing practices in line with global recommendations?

OBJECTIVE

To describe changing primary care ordering of serum 25-hydroxyvitamin D (25OHD) tests in Australian children.

DESIGN

Longitudinal, population-based descriptive study of 25OHD testing using a large administrative dataset of pathology orders and results, 2003-2018.

SETTING AND PARTICIPANTS

Three primary health networks in Victoria, Australia. Patients aged ≤18 years with a serum 25OHD test ordered by the general practitioner (GP).

MAIN OUTCOME MEASURES

Trends over 15 years in the number of 25OHD tests ordered, proportion indicating low levels or vitamin D deficiency and details of repeat testing.

RESULTS

Of 970 816 laboratory tests, 61 809 (6.4%) included an order for a 25OHD test. The 61 809 tests were performed in 46 960 children or adolescents. The odds of ordering a 25OHD test in 2018 was 30.4 times higher compared with 2003 (95%CI 22.6 to 40.8, p<0.001). The odds of detecting a low 25OHD (<50 nmol/L) compared with the baseline in 2003 remained steady (adjusted OR<1.5) over time. Repeat tests (14 849) were undertaken in 9626 patients (median intertest interval 357 days, IQR 172-669 days). A total of 4603 test results indicated vitamin D deficiency (<30 nmol/L), but in only 180 (3.9%) of these was a repeat test performed within 3 months as recommended.

CONCLUSION

Testing volumes increased 30-fold, but the odds of detecting low 25OHD remained steady. Current Australian policy and the Global Consensus Recommendations for the prevention and management of nutritional rickets do not support routine 25OHD testing. Education and electronic pathology ordering tools may assist GPs to better align practice with current recommendations.

Classification of Long COVID from General Practitioner Diagnosis Text

Major challenges exist in identifying Long COVID patients from diagnosis texts recorded by general practitioners. A classification framework is proposed that can be used to identify Long COVID patients given these unstructured diagnostic texts. This framework can be leveraged to provide a general understanding of the risk factors, management strategies, and outcomes associated with Long COVID in Australia.

Difference in general practice telehealth utilisation associated with birth country during COVID-19 from two Australian states

Objective

Telehealth has been an integral part of ensuring continued general practice access during the COVID-19 pandemic. Whether telehealth was similarly adopted across different ethnic, cultural, and linguistic groups in Australia is unknown. In this study, we assessed how telehealth utilisation differed by birth country.

Methods

In this retrospective observational study, electronic health record data from 799 general practices across Victoria and New South Wales, Australia between March 2020 to November 2021 were extracted (12,403,592 encounters from 1,307,192 patients). Multivariate generalised estimating equation models were used to assess the likelihood of a telehealth consultation (against face-to-face consultation) by birth country (relative to Australia or New Zealand born patients), education index, and native language (English versus others).

Results

Patients born in Southeastern Asia (aOR: 0.54; 95% CI: 0.52-0.55), Eastern Asia (aOR: 0.63; 95% CI: 0.60-0.66), and India (aOR: 0.64; 95% CI: 0.63-0.66) had a lower likelihood of having a telehealth consultation compared to those born in Australia or New Zealand. Northern America, British Isles, and most European countries did not present with a statistically significant difference. Additionally, higher education levels (aOR: 1.34; 95% CI: 1.26-1.42) was associated with an increase in the likelihood of a telehealth consultation, while being from a non-English-speaking country was associated with a reduced likelihood (aOR: 0.83; 95% CI: 0.81-0.84).

Conclusions

This study provides evidence showing differences in telehealth use associated with birth country. Strategies to ensure continued healthcare access for patients, whose native language is not English, such as providing interpreter services for telehealth consultations, would be beneficial.

Perspectives

Understanding cultural and linguistic differences may reduce health disparities in telehealth access in Australia and could present an opportunity to promote healthcare access in diverse communities.

Opioid prescribing among aged care residents during the first year of the COVID-19 pandemic: an analysis using general practice health records in Australia

BACKGROUND

Opioid use is common among adults 65 years and older, while long-term use of opioids remains controversial and poses risks of drug dependence and other adverse events. The acute disease caused by the SARS-CoV-2 (COVID-19) pandemic has created new challenges and barriers to healthcare access, particularly for long-term care residents. Australia had a relatively low incidence and deaths due to COVID-19 during the first year of the pandemic compared to most OECD countries. In this context, we examined opioid prescribing rates and their dosage in residential aged care facilities (RACFs) before (2019) and during the COVID-19 pandemic (2020) from March to December in Australia.

METHODS

We conducted a retrospective cohort using general practice electronic health records. This includes 17,304 RACF residents aged 65 years and over from 361 general practices in New South Wales and Victoria. Number of opioid prescriptions and percentage of opioids over 50 mg/day of oral morphine equivalent (OME) were described. Multivariate generalized estimating equations were applied to estimate odds ratios [aORs (95% confidence intervals)] for 1) opioids prescribed per consultation and 2) prescription opioids over 50 mg/day OME.

RESULTS

In 2020 among 11,154 residents, 22.8% of 90,897 total prescriptions were opioids, and of the opioids, 11.3% were over 50 mg/day OME. In 2019 among 10,506 residents, 18.8% of 71,829 total prescriptions were opioids, of which 10.3% were over 50 mg/day OME. Year [2020 vs. 2019: aOR (95% CI):1.50 (1.44, 1.56); 1.29 (1.15, 1.46)] and regionality [rural/regional vs. metropolitan: 1.37 (1.26, 1.49); 1.40 (1.14, 1.71)] were associated with higher odds of prescription opioids and OME > 50 mg/day, respectively. Similar results were found when limited to the same residents (n = 7,340) recorded in both years.

CONCLUSIONS

Higher prescription rates of opioids were observed during the COVID-19 pandemic in 2020 than in 2019 in Australian RACFs. The higher odds of prescription opioids and higher dosing in rural/regional than metropolitan areas indicate a widening of the gap in the quality of pain management during the pandemic. Our findings contribute to the limited data that indicate increased opioid prescriptions in long-term care facilities, likely to continue while COVID-19 pandemic restrictions remain.

A framework for conducting policy-relevant primary care research: a COVID-19 case study in Australia

The onset of the coronavirus disease 2019 (COVID-19) pandemic, caused by SARS-CoV-2, and the ensuing implementation of response measures directly impacted the delivery of Australian primary care services. Understanding how these measures affected practice activity is important for gauging both their effectiveness and implications for future service planning. During the first 2years of the COVID-19 pandemic, a research project was undertaken to determine the impact of the pandemic on Australian general practice activity as a collaborative undertaking between researchers, general practitioners, data custodians, and five primary health networks from New South Wales and Victoria, Australia. The project methodology was based on an established research approach called action research, which involves participatory involvement from key stakeholders throughout the research process. The strength and success of the project's methodological approach stemmed from the synergistic interrelationship between the four key elements of: collaboration, repeated action research cycles (utilising electronic general practice data), engaged governance, and the production and dissemination of apposite knowledge outcomes. The project approach, knowledge outputs and lessons learned can be adapted to future research undertakings across any primary care setting and highlight the utility of action research and interdisciplinary research collaboration to produce knowledge directly relevant to clinical practice.

Sociodemographic determinants of telehealth utilisation in general practice during the COVID-19 pandemic in Australia

This analysis assessed the sociodemographic characteristics of telehealth utilisation during the coronavirus disease 2019 (COVID-19) pandemic from March 2020 to August 2021 in Australia. Drawing on 860 general practice providers among 3 161 868 patients, 24 527 274 consultations were recorded. Telehealth accounted for 37.6% of the consultations, with 2.4% through videoconferencing and 35.2% through phone consultations. Our multivariate regression analyses indicated low utilisation of videoconferencing compared with phone consultations among older adults, those living in rural communities and migrants from non-English speaking countries.

Telehealth utilisation in residential aged care facilities during the COVID-19 pandemic: A retrospective cohort study in Australian general practice

INTRODUCTION

Our earlier analysis during the COVID-19 surges in 2020 showed a reduction in general practitioner (GP) in-person visits to residential aged care facilities (RACFs) and increased use of telehealth. This study assessed how sociodemographic characteristics affected telehealth utilisation.

METHODS

This retrospective cohort consists of 27,980 RACF residents aged 65 years and over, identified from general practice electronic health records in Victoria and New South Wales during March 2020-August 2021. Residents' demographic characteristics, including age, sex, region, and pension status, were analysed to estimate the odds ratio (OR) and 95% confidence interval (CI) for the associations with telehealth utilisation (telephone/video vs. in-person consultations) and with video versus telephone consultations, in mixed-effects multiple level regression models.

RESULTS

Of 32,330 median monthly GP consultations among 21,987 residents identified in 2020, telehealth visits accounted for 17% of GP consultations, of which 93% were telephone consults. In 2021, of 32,229 median monthly GP consultations among 22,712 residents, telehealth visits accounted for 11% of GP consultations (97% by telephone). Pension holders (OR: 1.14; 95% CI: 1.10, 1.17) and those residing in rural areas (OR: 1.72; 95% CI: 1.57, 1.90) were more likely to use telehealth. However, residents in rural areas were less likely to use video than telephone in GP consultations (OR: 0.41; 95% CI: 0.29, 0.57). Results were similar in separate analyses for each COVID surge.

DISCUSSION

Telephone was primarily used in telehealth consultations among pension holders and rural residents in RACFs. Along with the limited use of video in virtual care in rural RACFs, the digital divide may imply potential healthcare disparities in socially disadvantaged patients.

Assessment of analytical bias in ferritin assays and impact on functional reference limits

Serum ferritin is currently the recommended laboratory test to investigate iron deficiency. There have been efforts to standardise serum ferritin assays with implementation of traceability to the World Health Organization reference standard. We evaluate the analytical bias among five widely used commercial ferritin assays in Australia. The relationship between serum ferritin and erythrocyte parameters was recently explored to derive functional reference limits. Residual patient serum specimens were analysed by five participating laboratories that utilised a different ferritin assay, Abbott, Beckman Coulter, Roche, Siemens, and Ortho. Using data mining approach, functional reference limits for Siemens, Abbott, and Ortho serum ferritin methods were derived and compared. At clinically relevant ferritin decision points, compared to the Beckman method, the Roche assay showed higher results ranging from 6 μg/L (31%) at the lowest decision point to 575 μg/L (57%) at the highest decision point. In contrast, the Ortho method underestimated ferritin results at lower decision points of 20 and 30 μg/L, with estimated ferritin results of 16 μg/L (-19%) and 27 μg/L (-12%), respectively. The Abbott and Siemens assays showed a positive bias which was introduced at differing decision points. The comparison of the Siemens and Ortho methods presents similar inflection points between the two assays in the establishment of functional reference limits for serum ferritin. There remain significant biases among some of the commonly used commercial ferritin assays in Australia. More studies are needed to assess if functional reference limits are a way to overcome method commutability issues.

COVID-19: protocol for observational studies utilizing near real-time electronic Australian general practice data to promote effective care and best-practice policy-a design thinking approach

BACKGROUND

Health systems around the world have been forced to make choices about how to prioritize care, manage infection control and maintain reserve capacity for future disease outbreaks. Primary healthcare has moved into the front line as COVID-19 testing transitions from hospitals to multiple providers, where tracking testing behaviours can be fragmented and delayed. Pooled general practice data are a valuable resource which can be used to inform population and individual care decision-making. This project aims to examine the feasibility of using near real-time electronic general practice data to promote effective care and best-practice policy.

METHODS

The project will utilize a design thinking approach involving all collaborators (primary health networks [PHNs], general practices, consumer groups, researchers, and digital health developers, pathology professionals) to enhance the development of meaningful and translational project outcomes. The project will be based on a series of observational studies utilizing near real-time electronic general practice data from a secure and comprehensive digital health platform [POpulation Level Analysis and Reporting (POLAR) general practice data warehouse]. The study will be carried out over 1.5 years (July 2020-December 2021) using data from over 450 general practices within three Victorian PHNs and Gippsland PHN, Eastern Melbourne PHN and South Eastern Melbourne PHN, supplemented by data from consenting general practices from two PHNs in New South Wales, Central and Eastern Sydney PHN and South Western Sydney PHN.

DISCUSSION

The project will be developed using a design thinking approach, leading to the building of a meaningful near real-time COVID-19 geospatial reporting framework and dashboard for decision-makers at community, state and nationwide levels, to identify and monitor emerging trends and the impact of interventions/policy decisions. This will integrate timely evidence about the impact of the COVID-19 pandemic related to its diagnosis and treatment, and its impact across clinical, population and general practice levels.

Influence of serum iron test results on the diagnosis of iron deficiency in children: a retrospective observational study

BACKGROUND AND OBJECTIVE

Serum iron results are not indicative of iron deficiency yet may be incorrectly used to diagnose iron deficiency instead of serum ferritin results. Our objective was to determine the association between serum iron test results and iron-deficiency diagnosis in children by general practitioners.

DESIGN, SETTING, PATIENTS AND MAIN OUTCOME MEASURES

A retrospective observational study of 14 187 children aged 1-18 years with serum ferritin and serum iron test results from 137 general practices in Victoria, Australia, between 2008 and 2018. Generalised estimating equation models calculating ORs were used to determine the association between serum iron test results (main exposure measure) and iron-deficiency diagnosis (outcome measure) in the following two population groups: (1) iron-deplete population, defined as having a serum ferritin <12 µg/L if aged <5 years and <15 µg/L if aged ≥5 years and (2) iron-replete population, defined as having a serum ferritin >30 µg/L.

RESULTS

3484 tests were iron deplete and 15 528 were iron replete. Iron-deplete children were less likely to be diagnosed with iron deficiency if they had normal serum iron levels (adjusted OR (AOR): 0.73; 95% CI 0.57 to 0.96). Iron-replete children had greater odds of an iron-deficiency diagnosis if they had low serum iron results (AOR: 2.59; 95% CI 1.72 to 3.89). Other contributors to an iron-deficiency diagnosis were female sex and having anaemia.

CONCLUSION

Serum ferritin alone remains the best means of diagnosing iron deficiency. Reliance on serum iron test results by general practitioners is leading to significant overdiagnosis and underdiagnosis of iron deficiency in children.

Functional reference limits: a case study of serum ferritin

Reference intervals depend on the distribution of results within a reference population and can be influenced by subclinical disease. Functional reference limits present an opportunity to derive clinically relevant reference limits from routinely collected data sources, which consist of mixed populations of unhealthy and healthy groups. Serum ferritin is a good example of the utility of functional reference limits. Several studies have identified clinically relevant reference limits through examining the relationship between serum ferritin and erythrocyte parameters. These ferritin functional limits often represent the inflection point at which erythrocyte parameters change significantly. Comparison of ferritin functional reference limits with those based on population distributional reference limits reveals that the lower reference limit may fall below the point at which patients become clinically unwell. Functional reference limits may be considered for any biomarker that exhibits a correlated relationship with other biomarkers.

Clinical thresholds for diagnosing iron deficiency: comparison of functional assessment of serum ferritin to population based centiles

Low serum ferritin is diagnostic of iron deficiency, yet its published lower cut-off values are highly variable, particularly for pediatric populations. Lower cut-off values are commonly reported as 2.5th percentiles, and is based on the variation of ferritin values in the population. Our objective was to determine whether a functional approach based on iron deficient erythropoiesis could provide a better alternative. Utilizing 64,443 ferritin test results from pediatric electronic health records, we conducted various statistical techniques to derive 2.5th percentiles, and also derived functional reference limits through the association between ferritin and erythrocyte parameters: hemoglobin, mean corpuscular volume, mean cell hemoglobin concentration, and red cell distribution width. We find that lower limits of reference intervals derived as centiles are too low for clinical interpretation. Functional limits indicate iron deficiency anemia starts to occur when ferritin levels reach 10 µg/L, and are largely similar between genders and age groups. In comparison, centiles (2.5%) presented with lower limits overall, with varying levels depending on age and gender. Functionally-derived limits better reflects the underlying physiology of a patient, and may provide a basis for deriving a threshold related to treatment of iron deficiency and any other biomarker with functional outcomes.

Harnessing the potential of electronic general practice pathology data in Australia: An examination of the quality use of pathology for type 2 diabetes patients

BACKGROUND

Despite the importance of pathology testing in diagnosis and disease monitoring, there is little in-depth research about pathology test ordering in general practice and how it impacts patient outcomes. This is in part due to the limited availability of high-quality data. With the now-widespread use of electronic software in general practice comes the potential for electronic patient data to be used for research leading to better understanding of general practice activities, including pathology testing.

OBJECTIVES

This study aimed to examine the usefulness of electronic general practice pathology data to: (1) identify patients' characteristics, (2) monitor quality of care, (3) evaluate intervention effects, (4) identify variations in patient care, and (5) measure patient outcomes. An exemplar study evaluating kidney function testing in type 2 diabetes mellitus (type 2 diabetes) compared to guidelines was used to demonstrate the value of pathology data.

MATERIALS AND METHODS

De-identified electronic data from approximately 200 general practices in Victoria were extracted using Outcome Health's Population Level Analysis & Reporting (POLAR) Aurora research platform. Our study population included patients ≥18 diagnosed with type 2 diabetes before July 2016. Data from July 2016 to June 2018 were used to i) determine frequency of kidney function tests (KFT), and ii) identify whether antihypertensive medications were prescribed for abnormal KFT results.

RESULTS

There were 20,514 active patients with type 2 diabetes identified from the data. The age and gender standardised estimate of diabetes prevalence was 4.9%, consistent with Australian estimates (5.2%). Sociodemographic features of prevalence, including higher prevalence in older males, were also consistent with previous Australian estimates. Kidney function testing was performed annually, as recommended by guidelines, in 75.7% of patients, with higher annual testing observed in patients managed under general practice incentive programs (80.1%) than those who were not (72.2%). Antihypertensive medications were prescribed as recommended in 77.4% of patients with suspected microalbuminuria or macroalbuminuria based on KFT results.

DISCUSSION

Evaluations using data from diabetes patients in this study illustrate the value of electronic data for identifying patients with the condition of interest (e.g. type 2 diabetes) along with sociodemographic characteristics. This allows for the ability to undertake analyses on pathology testing factors and the identification of variation compared to guidelines, which has a potential to ensure quality of care. Its potential to identify associations with incentive programs further demonstrates the advantages of the data's longitudinal nature. These include the ability to assess temporal order and time interval of tests as a marker of quality of monitoring and evaluate intervention effects on a cohort over time. Finally, analyses on antihypertensive medication prescribing in patients with suspected micro/macroalbuminuria exemplified the electronic data's usefulness in monitoring patient outcomes, such as appropriate prescribing based on pathology test results.

CONCLUSIONS

Electronic general practice data is an important resource which can provide valuable insights about the quality use of pathology. There are clear benefits to patients for better monitoring, and consequent better outcomes, and to inform policymakers about the best ways to channel resources to enhance the quality of care.

Laboratory Test Utilization and Repeat Testing for Inpatients of Age 80 and Over in Australia: A Retrospective Observational Study

Introduction

Repeat laboratory testing is often necessary in hospitals. However, frequent blood draws can be harmful to older patients. The objective of this study was to identify the most frequently ordered laboratory tests and repeat testing rates for these tests among older inpatients.

Methods

A retrospective observational study of inpatients of age 80 years and over in 4 public hospitals in New South Wales, Australia, was conducted between 2008 and 2013. Proportions of laboratory tests and proportions of repeated tests among the most frequently used tests were reported.

Results

There were 42739 patients with 108003 admissions (56.2% women; 43.2% of ages 80–84). Of these admissions, 95.9% had a laboratory test, with 3012577 tests recorded. Five tests accounted for 62% of all tests and were present in 98.5% of admissions: electrolytes urea and creatinine (EUC; 18% of all tests ordered), complete blood count (CBC; 16.7%), calcium magnesium phosphate (CaMgPhos; 10.2%), liver function test (LFT; 9.0%), and C-reactive protein (CRP; 8.0%). Proportions of repeat tests for this group performed outside recommended minimum repeat intervals were 10.3% EUC, 8.9% CBC, 41.5% CRP, 68.2% CaMgPhos, and 65.2% LFT tests. An exponential increase in repeat testing for all 5 tests was observed around 24 h after a previous test.

Conclusion

Compliance with guidelines on repeat testing intervals among older patients is variable. A better understanding of the underlying reasons for repeat testing would allow targeting of interventions, including decision support, to improve laboratory use for older inpatients.

Who Gets a Laboratory Test in Hospital, Why, and How Often? A Retrospective Observational Study of 4 Australian Hospitals

BACKGROUND

Laboratory providers are challenged with the need to deliver improvements in the efficiency and effectiveness of laboratory services. Initiatives have been set to reduce the inappropriate use of tests; however, empirical evidence about the rate and frequency of laboratory tests in hospitals has not been widely available. This study used data linkage techniques to investigate laboratory test use among Australian inpatients.

METHODS

A retrospective observational study was conducted across 3 metropolitan and 1 rural hospital, all serviced by a single laboratory provider. Data for all admitted inpatients between January 2008 and December 2013 were extracted and linked to determine the proportion of admissions with a laboratory test, number of tests per admission, and time to first test.

RESULTS

This study included 521480 admissions. Of these, 83.7% had a pathology test. Newborns and neonates had the lowest percentage of admissions with tests (35.2%), whereas admissions for diseases and disorders of the hepatobiliary system and pancreas had the highest (97.5%). Patients had a median of 12 tests per admission. Patients 80-84 years of age had the highest rate of tests per admission (median, 19; interquartile range, 9-36). Forty-nine percent of patients' first tests occurred within 2 h of admission, increasing to 69.9% within 4 h.

CONCLUSION

The vast majority of patients admitted to hospital received laboratory tests. Higher laboratory testing rates were observed with increasing age. These findings can be used to define and compare laboratory testing among inpatients and help identify sources of variation in laboratory testing.

Diagnostic Informatics: Its Role in Enhancing Clinical Excellence, Patient Safety and the Value of Care

Diagnostic informatics encompasses the role of information technology in key areas of the diagnostic testing (pathology and medical imaging) process, including the selection of appropriate tests and interpretation and follow-up of test results. We present three case studies employing diagnostic informatics methodologies to demonstrate their potential use and value in health services research: (1) Data analytics applied to diagnostic data linked with patient outcome data as a means of enhanancing the monitoring of the quality and appropriateness of diagnostic test choices; (2) Business process modelling which can help to highlight healthcare processes in the diagnostic pathway as a means of improving safety and performance, and (3) Consumer involvement in the diagnostic research process to assist in the establishment of person-centred test result management systems. The case studies provide evidence of the role that diagnostic informatics can have in improving the quality and safety of patient care.

Compliance with pathology testing guidelines in Australian general practice: protocol for a secondary analysis of electronic health record data

INTRODUCTION

In Australia, general practitioners usually are the first point of contact for patients with non-urgent medical conditions. Appropriate and efficient utilisation of pathology tests by general practitioners forms a key part of diagnosis and monitoring. However overutilisationand underutilisation of pathology tests have been reported across several tests and conditions, despite evidence-based guidelines outlining best practice in pathology testing. There are a limited number of studies evaluating the impact of these guidelines on pathology testing in general practice. The aim of our quantitative observational study is to define how pathology tests are used in general practice and investigate how test ordering practices align with evidence-based pathology guidelines.

METHODS AND ANALYSIS

Access to non-identifiable patient data will be obtained through electronic health records from general practices across three primary health networks in Victoria, Australia. Numbers and characteristics of patients, general practices, encounters, pathology tests and problems managed over time will be described. Overall rates of encounters and tests, alongside more detailed investigation between subcategories (encounter year, patient's age, gender, and location and general practice size), will also be undertaken. To evaluate how general practitioner test ordering coincides with evidence-based guidelines, five key candidate indicators will be investigated: full blood counts for patients on clozapine medication; international normalised ratio measurements for patients on warfarin medication; glycated haemoglobin testing for monitoring patients with diabetes; vitamin D testing; and thyroid function testing.

ETHICS AND DISSEMINATION

Ethics clearance to collect data from general practice facilities has been obtained by the data provider from the RACGP National Research and Evaluation Ethics Committee (NREEC 17-008). Approval for the research group to use these data has been obtained from Macquarie University (5201700872). This study is funded by the Australian Government Department of Health Quality Use of Pathology Program (Agreement ID: 4-2QFVW4M). Findings will be reported to the Department of Health and disseminated in peer-reviewed academic journals and presentations (national and international conferences, industry forums).

Delivering safe and effective test-result communication, management and follow-up: a mixed-methods study protocol

INTRODUCTION

The failure to follow-up pathology and medical imaging test results poses patient-safety risks which threaten the effectiveness, quality and safety of patient care. The objective of this project is to: (1) improve the effectiveness and safety of test-result management through the establishment of clear governance processes of communication, responsibility and accountability; (2) harness health information technology (IT) to inform and monitor test-result management; (3) enhance the contribution of consumers to the establishment of safe and effective test-result management systems.

METHODS AND ANALYSIS

This convergent mixed-methods project triangulates three multistage studies at seven adult hospitals and one paediatric hospital in Australia.Study 1 adopts qualitative research approaches including semistructured interviews, focus groups and ethnographic observations to gain a better understanding of test-result communication and management practices in hospitals, and to identify patient-safety risks which require quality-improvement interventions.Study 2 analyses linked sets of routinely collected healthcare data to examine critical test-result thresholds and test-result notification processes. A controlled before-and-after study across three emergency departments will measure the impact of interventions (including the use of IT) developed to improve the safety and quality of test-result communication and management processes.Study 3 adopts a consumer-driven approach, including semistructured interviews, and the convening of consumer-reference groups and community forums. The qualitative data will identify mechanisms to enhance the role of consumers in test-management governance processes, and inform the direction of the research and the interpretation of findings.

ETHICS AND DISSEMINATION

Ethical approval has been granted by the South Eastern Sydney Local Health District Human Research Ethics Committee and Macquarie University. Findings will be disseminated in academic, industry and consumer journals, newsletters and conferences.

Pending Laboratory Test Results at the Time of Discharge: A 3-Year Retrospective Comparison of Paper Versus Electronic Test Ordering in Three Emergency Departments

Pending laboratory test results at discharge can have major adverse health outcomes. The availability of test results at discharge may depend on whether the tests were ordered electronically or by using a paper-based system. The aim of this study was to determine the rate of pending test results at time of discharge from Emergency Departments (ED), and compare the rate for paper-based and electronic orders across three EDs in New South Wales, Australia. This retrospective study described 71,466 ED presentations with 357,476 laboratory tests across three years (2014-2016). Only patients who were treated in ED and eventually discharged from ED were included. Most tests were ordered using the electronic system (97.2%, n=347,469). The rate of pending test results was significantly lower for electronic orders (6.6%, n=22,928) than for paper orders (9.7%, n=966): a difference of 3.1%. Similar differences were observed when analysis was done by year of ED presentation. Moreover, in a subgroup analysis that included the top five high volume tests, four of the five tests had significantly lower rates of pending test results for electronic orders than for paper-based orders. The study highlighted an important benefit of ordering tests via electronic system which can potentially improve patient outcomes.

Dentists' knowledge about anaphylaxis caused by local anaesthetics

BACKGROUND

IgE-mediated systemic reactions to local anaesthetics may be seen--although rarely--by dentists. However, it is not known whether dentists are familiar with symptoms, signs and management of anaphylaxis.

METHODS

In this study we aimed to evaluate knowledge of dentists of the symptoms and signs and current treatment of anaphylaxis. For this, some dentists working in their private offices in Istanbul were asked to complete an anonymous questionnaire with 15 questions related to anaphylaxis.

RESULTS

A total of 86 dentists agreed to participate in the study. None of the attendants were completely aware of the symptoms and signs of anaphylaxis. About half of the attendants (48.8%) knew epinephrine as the first drug in the treatment of anaphylaxis and keep it in their offices (55.6%), but only one third of the dentists (31.5%) preferred intramuscular route as the most effective route for epinephrine injection.

CONCLUSION

Our data show that the level of dentists' knowledge of local anaesthetics allergy and anaphylaxis is inadequate. This may endanger patients' lives. An educational programme that may improve general dentists' knowledge about local anaesthetics allergy and anaphylaxis is urgently necessary.

Leukocytoclastic vasculitis in a child with epidermolysis bullosa simplex

A 10-year-old boy with epidermolysis bullosa simplex (Weber-Cockayne variant) together with leukocytoclastic vasculitis is presented. He was admitted to the hospital with the provisional diagnoses of infected epidermolysis bullosa simplex or drug eruption. On the sixth day of hospitalization he developed palpable purpura, abdominal pain and bloody diarrhea, together with hematuria and proteinuria. A generalized tonic-clonic convulsion, changes in mental status, fluctuations in arterial blood pressure and intractable pain in his extremities occurred during the course of hospitalization. Systemic pulse steroid therapy, antibiotics, and antihypertensive and anticonvulsive drugs were given. On the 30th day of hospitalization, a skin graft was performed to replace a large tissue defect on his left hand. Despite high dose steroid therapy, his hematuria, proteinuria and hypertension continued after his discharge, suggesting a steroid-resistant renal pathology, such as focal glomerulosclerosis, that occurred secondary to leukocytoclastic vasculitis.
