RESUMO
INTRODUCTION: The swift uptake of new medications into clinical practice has many benefits; however, slow uptake has been seen previously with other guideline-directed medical therapies (GDMT) in heart failure (HF). Sodium glucose co-transporter 2 inhibitors are a novel therapy in HF proven to be efficacious and will have beneficial clinical outcomes if prescribed. Understanding physician perspectives on prescribing GDMT in HF can help target strategies to bridge the gap between guidelines and practice. METHODS: The study followed the PRISMA guide for scoping reviews. A search was conducted using EMBASE, Medline, and PubMed databases in April 2024. Studies included were those using qualitative methods to assess physician perspectives towards prescribing any HF medication. Common themes were identified through thematic synthesis following the methods from Cochrane Training and using software MAXQDA Analysis Pro. RESULTS: 708 studies were found in the search, with 23 full studies included. The most pertinent barriers identified were concern for medication adverse effects, unclear role responsibilities between physicians of different specialities, patient co-morbidities, and unwillingness to alter therapies of stable patients. The most identified enablers included awareness of efficacy, influence from colleagues, and the use of multi-media approaches for information dissemination. Perceptions were also found to change over time and vary among prescriber groups. CONCLUSIONS: Physicians perceive common barriers and enablers of prescribing GDMT in HF, despite differences in prescriber groups and time periods. The identified barriers and enablers may be targeted to improve implementation of GDMT into clinical practice.

Little is known about the contribution of general medicine to perioperative and consultative care in Australia. A descriptive observational study was undertaken at a quaternary institution to evaluate the characteristics of perioperative and nonoperative consultations undertaken by general medicine. Results demonstrated patterns of engagement within a 'traditional' model of perioperative care and highlighted several opportunities for a redesign to a more proactive and collaborative cross-disciplinary model.

PURPOSE: To develop a reliable assessment tool to monitor the quality of adverse drug reaction (ADR) reports and evaluate its performance within a quaternary hospital setting. METHODS: Adverse drug reactions report QUality Algorithm (AQUA-12) was developed by a multidisciplinary team with the expertise in the management of ADRs. The design was based on data elements required to establish medication causality. Inter-rater reliability of AQUA-12 was evaluated over three rounds in two phases: development and prospective evaluation phases, by independent assessors both internal and external to the institutional ADR review processes. The characteristics and quality of ADR reports were subsequently assessed, and potential factors contributing to low-quality reports were identified. RESULTS: A total of 70 ADR reports were assessed, 20 in development and 50 in evaluation phases. The inter-rater reliability of AQUA-12 was found to be excellent in all three rounds (Cronbach's alpha of ≥ 0.9, p < 0.001 for all). Approximately one in five reports concerned immediate hypersensitivity reactions while delayed hypersensitivity reactions constituted 60% of all reactions. AQUA-12 identified 18 (25.7%) reports as 'low-quality' with a score of < 10. Identification of suspected medications (37.1%), description of index ADR (27.1%), and key events (ADR narrative, 35.7%) were the top data elements incomplete or missing from all reports. Univariable analyses identified the severity of the reaction as a factor associated with low quality of reports (p = 0.008). CONCLUSIONS: AQUA-12 is a practical and highly reliable assessment tool that can be utilised in hospital settings to regularly monitor the completeness of ADR reports to guide quality improvement initiatives.

BACKGROUND: Risk factors and outcomes associated with severe epistaxis are not well understood. This study explores the associations between epistaxis severity, comorbidities, use of antiplatelets or anticoagulants and management outcomes. METHODS: This is a retrospective cross-sectional study of all epistaxis cases presenting to the emergency department at a tertiary academic hospital from January 2016 to December 2019. Epistaxis severity was defined as mild (no intervention), moderate (required cautery and/or packing) and severe (clinical instability with reversal products, surgical or radiological intervention). Univariable and multivariable regression analyses were undertaken, with risk factors and management outcomes analysed according to severity. RESULTS: A total of 543 patients with epistaxis (54.2% male, mean age 74.4 ± 15.7 years) were included in this study, with 14.7% (80) having severe epistaxis. Of these presentations 216 (39.8%) were on antiplatelets, while 207 (38.1%) were on anticoagulants. In univariate analyses, clopidogrel use, hereditary haemorrhagic telangiectasia (HHT), haematological malignancy, bleeding disorders and chronic liver disease (CLD) were associated with moderate to severe epistaxis (P < 0.05), while the use of rivaroxaban was inversely associated severity (P = 0.002). Only HHT, haematological malignancy and CLD remained significant in multivariate models. Cautery as first-line management was infrequently utilized while anticoagulation was frequently withheld. A longer length of stay (1.1 days vs. 4.3 days; P < 0.001) and higher 2-week readmission rates (2.2% vs. 12.5%; P < 0.001) were noted with severe epistaxis compared with mild presentations. CONCLUSION: Epistaxis severity is associated with certain clinical conditions and poor outcomes. Despite recommended guidelines, variations in first-line management were evident.

BACKGROUND: General medicine is an integral part of health services, yet there is little data highlighting their contribution to acute hospital care in Australia. AIMS: To utilise the Victorian Department of Health's administrative dataset for hospital admissions to evaluate the relative contribution and trends over time of general medical services to acute multiday inpatient hospital separations in the Victorian public healthcare system. METHODS: A retrospective time-series study of general medical activity compared to other major specialties using hospital-level data provided by the Department of Health: (i) extrapolation from diagnosis-related group (DRG) activity data (2011-2021) and, (ii) directly reported discharge unit-based activity (available from 2018). Acute multiday separations of all patients aged ≥18 years from all metropolitan and rural Victorian public hospitals were included. RESULTS: Using the DRG-based data, general medicine ranked as the largest care provider of all specialties studied, accounting for 12.1% of separations. Despite the largest increase at a rate of 2831 separations/year (0.336%/year of total, P < 0.001) compared to others, mean length of stay declined by 0.08 days/year (P < 0.001). These findings were significant for metropolitan and rural hospitals. The use of directly reported discharge unit-based data also ranked general medicine as the largest care provider accounting for 32.9% of total separations, with rural hospital general medical services contributing nearly 50% of all multiday separations. CONCLUSIONS: Both DRG-based data and discharge unit-based data indicate that general medicine is the largest provider of acute multiday inpatient care in Victorian hospitals. The estimate of contribution of general medicine differed between the two datasets as DRG data likely over-represents the role of other specialties possibly due to assumptions regarding specialty management of varying groups of diagnoses.
RESUMO
INTRODUCTION: Severe cutaneous adverse reactions (SCAR) are a group of T cell-mediated hypersensitivities associated with significant morbidity, mortality and hospital costs. Clinical phenotypes include Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) and acute generalised exanthematous pustulosis (AGEP). In this Australasian, multicentre, prospective registry, we plan to examine the clinical presentation, drug causality, genomic predictors, potential diagnostic approaches, treatments and long-term outcomes of SCAR in Australia and New Zealand. METHODS AND ANALYSIS: Adult and adolescent patients with SCAR including SJS, TEN, DRESS, AGEP and another T cell-mediated hypersensitivity, generalised bullous fixed drug eruption, will be prospectively recruited. A waiver of consent has been granted for some sites to retrospectively include cases which result in early mortality. DNA will be collected for all prospective cases. Blood, blister fluid and skin biopsy sampling is optional and subject to patient consent and site capacity. To develop culprit drug identification and prevention, genomic testing will be performed to confirm human leukocyte antigen (HLA) type and ex vivo testing will be performed via interferon-γ release enzyme linked immunospot assay using collected peripheral blood mononuclear cells. The long-term outcomes of SCAR will be investigated with a 12-month quality of life survey and examination of prescribing and mortality data. ETHICS AND DISSEMINATION: This study was reviewed and approved by the Austin Health Human Research Ethics Committee (HREC/50791/Austin-19). Results will be published in peer-reviewed journals and presented at relevant conferences. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12619000241134).

PURPOSE: Adverse drug reactions (ADRs) contribute significantly to healthcare burden. However, they are largely preventable through appropriate management processes. This narrative review aims to identify the quality indicators that should be considered for routine monitoring of processes within hospital ADR management systems. It also examines the potential reasons behind variation in ADR management practices amongst HCPs, and explores possible solutions, focusing on targeted education programmes, to improve both the quality and quantity indicators of ADR management processes. METHODS: A comprehensive literature review was conducted to explore relevant themes and topics concerning ADR management, quality indicators and educational interventions. RESULTS: Substantial variability exists in ADR management amongst healthcare professionals (HCPs) with regard to reporting rates, characteristics of ADRs reported, quality of assessment, completeness of reports and, most importantly, risk communication practices. These variable practices not only threaten patient safety but also undermine pharmacovigilance processes. To date, quality indicators to monitor ADR management practices within hospital settings remain ill-defined. Furthermore, evidence behind effective interventions, especially in the form of targeted education strategies, to improve the quality of ADR management remains limited. CONCLUSIONS: The focus of ADR management in hospitals should be to promote patient safety through comprehensive assessment, risk communication and safe prescribing. There is a need to develop a system to define, measure and monitor the quality of ADR management. Educational strategies may help improve the quality of ADR management processes.

Background: Drug-induced severe cutaneous adverse reactions (SCARs) are presumed T-cell-mediated hypersensitivities associated with significant morbidity and mortality. Traditional in vivo testing methods, such as patch or intradermal testing, are limited by a lack of standardization and poor sensitivity. Modern approaches to testing include measurement of IFN-γ release from patient PBMCs stimulated with the suspected causative drug. Objective: We sought to improve ex vivo diagnostics for drug-induced SCARs by comparing enzyme-linked immunospot (ELISpot) sensitivities and flow cytometry-based intracellular cytokine staining and determination of the cellular composition of separate samples (PBMCs or blister fluid cells [BFCs]) from the same donor. Methods: ELISpot and flow cytometry analyses of IFN-γ release were performed on donor-matched PBMC and BFC samples from 4 patients with SCARs with distinct drug hypersensitivity. Results: Immune responses to suspected drugs were detected in both the PBMC and BFC samples of 2 donors (donor patient 1 in response to ceftriaxone and case patient 4 in response to oxypurinol), with BFCs eliciting stronger responses. For the other 2 donors, only BFC samples showed a response to meloxicam (case patient 2) or sulfamethoxazole and its 4-nitro metabolite (case patient 3). Consistently, flow cytometry revealed a greater proportion of IFN-γ-secreting cells in the BFCs than in the PBMCs. The BFCs from case patient 3 were also enriched for memory, activation, and/or tissue recruitment markers over the PBMCs. Conclusion: Analysis of BFC samples for drug hypersensitivity diagnostics offers a higher sensitivity for detecting positive responses than does analysis of PBMC samples. This is consistent with recruitment (and enrichment) of cytokine-secreting cells with a memory/activated phenotype into blisters.
RESUMO
BACKGROUND: Hospital wards are a complex and dynamic environment that rely on optimal staff performance. However, there is little research evaluating group interventions to improve staff attention and teamwork. AIMS: To evaluate whether a regular, short and guided group mindfulness practice for staff in an acute general medicine team improves attention and teamwork. METHODS: A 10-min programme comprising mindfulness exercises and techniques was delivered daily to a multidisciplinary general medicine team based in a tertiary hospital for 4 weeks. This was undertaken immediately prior to the team's interdisciplinary ward round. We used a mixed-method design, with self-rated surveys to measure mindfulness and staff perception of hospital safety culture, and a focus group to understand participants' experiences. We estimated mean differences using Kruskal-Wallis tests across 10 time-points and thematically analysed recorded transcripts. RESULTS: There was an increase in staff attention to the team meeting as measured by the decentering domain across time (P < 0.001). There was a trend to greater staff openness with a non-significant increase in curiosity (P = 0.14). We identified two overarching qualitative themes: feasibility of the programme and impact on staff and workplace. The programme was a calming circuit breaker to staff's day, which aided in feeling more connected to the group and subjectively better ward round experience. The logistics of the programme, including timing, and the facilitator developing trust with the participants, appear important in implementation. CONCLUSION: A brief mindfulness-based intervention delivered to a general medical team improves staff attention at a multidisciplinary team meeting and team functioning.

BACKGROUND: The use of in vivo and ex vivo diagnostic tools for delayed immune-mediated adverse drug reactions is currently ill defined. OBJECTIVE: To determine whether the combination of skin testing and/or IFN-γ enzyme-linked immunoSpot assay (ELISpot) can aid diagnosis of these allergy phenotypes. METHODS: Patients with antibiotic-associated severe delayed immune-mediated adverse drug reaction hypersensitivity, including Stevens-Johnson syndrome and toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis, generalized bullous fixed drug eruption, and severe maculopapular exanthema, were prospectively recruited. In vivo testing was completed to the implicated drug(s), and ex vivo testing was performed with the patient's PBMCs stimulated with the relevant antibiotic concentrations for IFN-γ release ELISpot measurement. RESULTS: Eighty-one patients met the inclusion criteria, with DRESS (42; 51.9%) accounting for most cases. Among the 63 (78%) who had an ELISpot assay performed, 34 (54%) were positive to at least 1 implicated antibiotic (median spot-forming units/million cells, 99.5; interquartile range, 68-187), with glycopeptide being a strong predictor of positivity (adjusted odds ratio, 6.11; 95% CI, 1.74-21.42). In combination (in vivo and ex vivo), 51 (63%) of those tested were positive to an implicated antibiotic. For DRESS and severe maculopapular exanthema associated with penicillins and cephalosporins, this combination confirmed the culprit agent in 11 of the 12 cases and in 6 of 7 for DRESS associated with glycopeptides. CONCLUSIONS: This study demonstrates that using in vivo in combination with ex vivo testing can enhance the diagnostic approach in these severe phenotypes by assisting with the identification of possible culprit antibiotics.

Severe drug hypersensitivity reactions (DHRs) are often encountered by health care professionals (HCPs). We evaluated knowledge of doctors and pharmacists in the assessment and management of severe DHRs using a structured questionnaire. A cross-sectional study was conducted in 4 metropolitan hospital networks in Melbourne, Australia. A 13-question, scenario-based multiple-choice questionnaire to assess specific knowledge domains in drug hypersensitivity syndrome recognition, causality attribution, cross-reactivity patterns, appropriate diagnostic tests, and therapy was administered to HCPs of various vocation and specialty groups. Data were analyzed according to profession, self-reported experience, and preparedness in managing severe DHRs. Two hundred thirty-eight participants (45.0% senior doctors, 24.4% junior doctors, and 30.7% pharmacists) across a range of subspecialties achieved an overall median score of 7 (IQR, 5-8)-overall 55.6% correct responses to all questions-with senior doctors outperforming junior doctors and pharmacists (P < .001). The best performance by all participants was in DHR syndrome recognition (60.9%), and the poorest was in diagnostics/therapy (52.0%). HCP group and experience level were significantly associated with better performance in the knowledge domains of cross-reactivity and diagnostics/therapy (P = .003 and < .001, respectively), but not in the domains of syndrome recognition and causality attribution (P > .05). Levels of self-reported preparedness in DHR management were not associated with performance rates in any of the knowledge domains. This study demonstrated significant knowledge gaps in the recognition and management of severe drug hypersensitivity reactions. Targeted multidisciplinary education of staff caring for these patients is needed to improve knowledge gaps.

BACKGROUND: Where an ongoing requirement for intravenous iron replacement exists after an index infusion reaction, current recommendations are limited to expert opinion and isolated case reports. OBJECTIVE: To evaluate the safety of recommencing an infusion or subsequent rechallenge following an infusion reaction to intravenous iron. METHODS: Infusion reactions to intravenous iron occurring between January 1, 2010, and December 31, 2019, at a metropolitan health network were identified. Patient characteristics, reaction type (mild, moderate, or severe hypersensitivity, delayed, or Fishbane: transient flushing and truncal myalgias), and outcomes of recommencing the index infusion or subsequent rechallenge were examined. RESULTS: Among 13,509 iron infusions, 195 infusion reactions occurred in 195 patients (1.4% of infusions). Recommencement of the index infusion (generally with a reduced infusion rate and premedication) was tolerated in 33 of 33 patients with Fishbane (20 of 20) or mild (9 of 9) and moderate (4 of 4) hypersensitivity reactions. Subsequent rechallenge (generally at standard infusion rates to an alternative formulation, ferric carboxymaltose) was successful in 68 of 69 patients with Fishbane (23 of 23), mild (26 of 26), moderate (16 of 17), and severe (3 of 3) hypersensitivity, or delayed (2 of 2) reactions. All 9 patients rechallenged to the original formulation (iron polymaltose) completed the infusion. CONCLUSIONS: Following an infusion reaction to intravenous iron infusion, recommencement of the index infusion is safe for Fishbane or mild and moderate hypersensitivity reactions. Subsequent rechallenge to an alternative formulation is tolerated, including in severe hypersensitivity reactions (albeit based on limited numbers). Where alternative formulations are not available, rechallenge to the same formulation could be considered, depending on the risk-benefit profile.
