Digital health competencies for the next generation of physicians.

As health care continues to change and evolve in a digital society, there is an escalating need for physicians who are skilled and enabled to deliver care using digital health technologies, while remaining able to successfully broker the triadic relationship among patients, computers and themselves. The focus needs to remain firmly on how technology can be leveraged and used to support good medical practice and quality health care, particularly around resolution of longstanding challenges in health care delivery, including equitable access in rural and remote areas, closing the gap on health outcomes and experiences for First Nations peoples and better support in aged care and those living with chronic disease and disability. We propose a set of requisite digital health competencies and recommend that the acquisition and evaluation of these competencies become embedded in physician training curricula and continuing professional development programmes.

Aiming to be NEAT: safely improving and sustaining access to emergency care in a tertiary referral hospital.

OBJECTIVE: To implement and evaluate strategies for improving access to emergency department (ED) care in a tertiary hospital. METHODS: A retrospective pre-post intervention study using routinely collected data involving all patients presenting acutely to the ED of a major tertiary hospital over a 2-year period. Main outcome measures were changes in: the percentage of patients exiting the ED (all patients, patients discharged directly from the ED, patients admitted to inpatient wards); mean patient transit times in the ED; inpatient mortality rates; rates of ED 'did not wait' and re-presentations within 48 h of ED discharge; and selected safety indicators. Qualitative data on staff perceptions of interventions were also gathered. RESULTS: Working groups focused on ED internal processes, ED-inpatient unit interface, hospital-wide discharge processes and performance monitoring and feedback. Twenty-five different reforms were enacted over a 9-month period from April to December 2012. Comparing the baseline period (January-March 2012) with the post-reform period (January-March 2013), the percentage of patients exiting the ED within 4 h rose for all patients presenting to the ED (from 32% to 62%), for patients discharged directly from the ED (from 41% to 75%) and for admitted patients (from 12% to 32%; P<0.001 for all comparisons). The mean (±s.d.) time all patients spent in the ED was reduced from 7.2±5.8 to 4.4±3.5 h (P<0.001) and, for admitted patients, was associated with reduced in-hospital mortality (from 2.3% to 1.7%; P=0.045). The 'did not wait' rates in ED fell from 6.9% to 1.9% (P<0.001), whereas ED re-presentations within 48 h among patients discharged from the ED rose slightly (from 3.1% to 3.8%; P=0.023). Improvements in outcome measures were maintained over the subsequent 12 months. CONCLUSIONS: Multiple reforms targeting processes both within the ED and its interface with inpatient units greatly improved access to ED care over 12 months and were associated with decreased in-hospital mortality. WHAT IS KNOWN ABOUT THIS TOPIC?: Prolonged stays in the ED result in overcrowding, delayed ambulance access to ED care and increased adverse outcomes for admitted patients. The introduction in Australia of National Emergency Access Targets (NEAT), which stipulate at least 70% of patients in the ED must exit the department within 4h, have spurred hospitals into implementing a wide range of reforms with varying levels of success in achieving such targets. WHAT DOES THIS PAPER ADD?: This study demonstrates how multiple reforms implemented in a poor performing tertiary hospital caused the proportion of patients exiting the ED within 4h to double within 9 months to reach levels comparable with best performing peer hospitals. This was associated with a 26% reduction in in-hospital mortality for admitted patients and no clinically significant adverse effects. It demonstrates the importance of robust governance structures, executive sponsorship, cross-disciplinary collaboration, regular feedback of NEAT performance data and major redesign of existing clinical processes, work practices and bed management operations. WHAT ARE THE IMPLICATIONS FOR CLINICIANS AND MANAGERS?: Improving access to emergency care should be regarded as a problem located and resolved both within and without the ED. It requires a whole-of-hospital solution involving interdisciplinary collaboration and significant change in culture and practice relating to inpatient units and their interface with the ED.

The effect of 25-hydroxyvitamin D on insulin sensitivity in obesity: is it mediated via adiponectin?

There has been substantial recent interest in using vitamin D to improve insulin sensitivity and preventing/delaying diabetes in those at risk. There is little consensus on the physiological mechanisms and whether the association is direct or indirect through enhanced production of insulin-sensitising chemicals, including adiponectin. We examined cross-sectional associations between serum 25-hydroxyvitamin D (25(OH)D) and insulin sensitivity (Matsuda index), parathyroid hormone (PTH), waist circumference, body mass index (BMI), triglycerides (TG), total and high molecular weight (HMW) adiponectin, HMW : total adiponectin ratio (HMW : total adiponectin), and total cholesterol : HDL cholesterol ratio (TC:HDL cholesterol) in 137 Caucasian adults of mean age 43.3 ± 8.3 years and BMI 38.8 ± 6.9 kg/m(2). Total adiponectin (standardised ß = 0.446; p < 0.001), waist circumference (standardised ß = -0.216; p < 0.05), BMI (standardised ß = -0.212; p < 0.05), and age (standardised ß = -0.298; p < 0.001) were independently associated with insulin sensitivity. Serum 25(OH)D (standardised ß = 0.114; p = 0.164) was not associated with insulin sensitivity, total or HMW adiponectin, HMW : total adiponectin, or lipids. Our results provide the novel finding that 25(OH)D is not associated with HMW adiponectin or HMW : total adiponectin in nondiabetic, obese adults and support the lack of association between 25(OH)D and lipids noted by others in similar groups of patients.

The Effect of Digitization on the Safe Management of Anticoagulants.

BACKGROUND: Anticoagulants are high-risk medications and are a common cause of adverse events of hospitalized inpatients. The incidence of adverse events involving anticoagulants has remained relatively unchanged over the past two decades, suggesting that novel approaches are required to address this persistent issue. Electronic medication management systems (eMMSs) offer strategies to help reduce medication incidents and adverse drug events, yet poor system design can introduce new error types. OBJECTIVE: Our objective was to evaluate the effect of the introduction of an electronic medical record (EMR) on the quality and safety of therapeutic anticoagulation management. METHODS: A retrospective, observational pre-/poststudy was conducted, analyzing real-world data across five hospital sites in a single health service. Four metrics were compared 1-year pre- and 1-year post-EMR implementation. They included clinician-reported medication incidents, toxic pathology results, hospital-acquired bleeding complications (HACs), and rate of heparin-induced thrombocytopenia. Further subanalyses of patients experiencing HACs in the post-EMR period identified key opportunities for intervention to maximize safety and quality of anticoagulation within an eMMS. RESULTS: A significant reduction in HACs was observed in the post-EMR implementation period (mean [standard deviation [SD]] =12.1 [4.4]/month vs. mean [SD] = 7.8 [3.5]/month; p = 0.01). The categorization of potential EMR design enhancements found that new automated clinical decision support or improved pathology result integration would be suitable to mitigate future HACs in an eMMS. There was no significant difference in the mean monthly clinician-reported incident rates for anticoagulants or the rate of toxic pathology results in the pre- versus post-EMR implementation period. A 62.5% reduction in the cases of heparin-induced thrombocytopenia was observed in the post-EMR implementation period. CONCLUSION: The implementation of an EMR improves clinical care outcomes for patients receiving anticoagulation. System design plays a significant role in mitigating the risks associated with anticoagulants and consideration must be given to optimizing eMMSs.

Toward a Learning Health Care System: A Systematic Review and Evidence-Based Conceptual Framework for Implementation of Clinical Analytics in a Digital Hospital.

OBJECTIVE: A learning health care system (LHS) uses routinely collected data to continuously monitor and improve health care outcomes. Little is reported on the challenges and methods used to implement the analytics underpinning an LHS. Our aim was to systematically review the literature for reports of real-time clinical analytics implementation in digital hospitals and to use these findings to synthesize a conceptual framework for LHS implementation. METHODS: Embase, PubMed, and Web of Science databases were searched for clinical analytics derived from electronic health records in adult inpatient and emergency department settings between 2015 and 2021. Evidence was coded from the final study selection that related to (1) dashboard implementation challenges, (2) methods to overcome implementation challenges, and (3) dashboard assessment and impact. The evidences obtained, together with evidence extracted from relevant prior reviews, were mapped to an existing digital health transformation model to derive a conceptual framework for LHS analytics implementation. RESULTS: A total of 238 candidate articles were reviewed and 14 met inclusion criteria. From the selected studies, we extracted 37 implementation challenges and 64 methods employed to overcome such challenges. We identified common approaches for evaluating the implementation of clinical dashboards. Six studies assessed clinical process outcomes and only four studies evaluated patient health outcomes. A conceptual framework for implementing the analytics of an LHS was developed. CONCLUSION: Health care organizations face diverse challenges when trying to implement real-time data analytics. These challenges have shifted over the past decade. While prior reviews identified fundamental information problems, such as data size and complexity, our review uncovered more postpilot challenges, such as supporting diverse users, workflows, and user-interface screens. Our review identified practical methods to overcome these challenges which have been incorporated into a conceptual framework. It is hoped this framework will support health care organizations deploying near-real-time clinical dashboards and progress toward an LHS.

Intensive care digital health response to emerging infectious disease outbreaks such as COVID-19.

The COVID-19 pandemic has required intensive care units to rapidly adjust and adapt their existing practices. Although there has a focus on expanding critical care infrastructure, equipment and workforce, plans have not emphasised the need to increase digital capabilities. The objective of this report was to recognise key areas of digital health related to the COVID-19 response. We identified and explored six focus areas relevant to intensive care, including using digital solutions to increase critical care capacity, developing surge capacity within an electronic health record, maintenance and downtime planning, training considerations and the role of data analytics. This article forms the basis of a framework for the intensive care digital health response to COVID-19 and other emerging infectious disease outbreaks.

Toilet Paper, Minced Meat and Diabetes Medicines: Australian Panic Buying Induced by COVID-19.

The COVID-19 pandemic has impacted the management of non-communicable diseases in health systems around the world. This study aimed to understand the impact of COVID-19 on diabetes medicines dispensed in Australia. Publicly available data from Australia's government subsidised medicines program (Pharmaceutical Benefits Scheme), detailing prescriptions by month dispensed to patients, drug item code and patient category, was obtained from January 2016 to November 2020. This study focused on medicines used in diabetes care (Anatomical Therapeutical Chemical code level 2 = A10). Number of prescriptions dispensed were plotted by month at a total level, by insulins and non-insulins, and by patient category (general, concessional). Total number of prescriptions dispensed between January and November of each year were compared. A peak in prescriptions dispensed in March 2020 was identified, an increase of 35% on March 2019, compared to average growth of 7.2% in previous years. Prescriptions dispensed subsequently fell in April and May 2020 to levels below the corresponding months in 2019. These trends were observed across insulins, non-insulins, general and concessional patient categories. The peak and subsequent dip in demand have resulted in a small unexpected overall increase for the period January to November 2020, compared to declining growth for the same months in prior years. The observed change in consumer behaviour prompted by COVID-19 and the resulting public health measures is important to understand in order to improve management of medicines supply during potential future waves of COVID-19 and other pandemics.

Altered clot kinetics in patients with non-alcoholic fatty liver disease.

BACKGROUND: Emerging evidence has linked the presence of non-alcoholic fatty liver disease (NAFLD) with an increased risk for cardiovascular events. We hypothesised that altered clot kinetics and platelet function may contribute to this increased risk. This study compared whole blood clotting kinetics in patients with 1) non-cirrhotic NAFLD (n = 28) and 2) healthy control subjects (n = 22). METHODS: Clotting kinetics were assessed in whole blood using thromboelastography (TEG) and assessed for correlations with cardiovascular risk factors. RESULTS: Clot kinetics in patients with NAFLD showed significantly stronger clot development (maximum amplitude (MA); 58.3 +/- 6.3 mm vs. 52.0 +/- 10.1 mm, p = 0.01) and reduced clot lysis in the presence of thrombin (35 +/- 30% vs. 51 +/- 26% clot lysis 30 minutes after MA, p = 0.03) compared to control subjects. Clot strength was independently positively associated with body mass index in NAFLD, but not in control subjects. There was a greater platelet contribution to clot strength in patients with NAFLD compared to controls despite similar platelet counts. There was no association between clot kinetics and features of the metabolic syndrome or presence of type 2 diabetes. CONCLUSION: Patients with NAFLD have disturbances in ex-vivo clot kinetics including increased clot strength and clots that are more resistant to thrombin-stimulated lysis.

RAGE polymorphisms and the heritability of insulin resistance: the Leeds family study.

UNLABELLED: Activation of the receptor for advanced glycation end-products (RAGE) leads to a cascade of pro-inflammatory and pro-coagulant responses which are important in the pathogenesis of the vascular complications of diabetes mellitus. It is known that pro-inflammatory mechanisms underpin the development of type 2 diabetes. Our hypothesis is that RAGE may be involved in the evolution of insulin resistance in addition to mediating glucotoxic complications of diabetes mellitus. METHODS: To investigate the relationship between RAGE allelic variation and insulin resistance, the Gly82Ser variant and three promoter variants (-429, -374, 63 bp deletion) were studied in 480 subjects of known relationship from 89 families characterised for insulin resistance (using homeostasis model assessment [HOMA]) and for atherothrombotic risk. Carriage of the -429 C allele was weakly associated with increased insulin resistance (p = 0.02) when pedigree analysis was performed using SOLAR software. RESULTS: Insulin resistance was estimated to have a heritability of 25.8% before the addition of covariates. Analysis of the relationship between RAGE and insulin resistance indicated that the -429 polymorphism reduced the unexplained heritability of insulin resistance after adjusting for covariates (age, sex, body mass index) from 17.5% of the total variance to 15.6% of the total variance. CONCLUSIONS: These preliminary results indicate that the RAGE gene may affect the development of insulin resistance or be in linkage disequilibrium with a locus involved in this process.
