Physician Perceptions of Medication Prescribing in Heart Failure: A Scoping Review.

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.

Development and application of Adverse drug reactions reports QUality Algorithm (AQUA-12) score: a single-centre quality improvement initiative.

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.

Contribution of general medicine to perioperative and consultative care: an Australian metropolitan teaching hospital experience.

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.

Adverse drug reaction management in hospital settings: review on practice variations, quality indicators and education focus.

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.

Understanding the contribution of general medical services to acute inpatient care in Victorian public hospitals.

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.

Collective pause: improving staff performance in acute medicine through a brief mindfulness-based group programme.

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.

Cost-analysis of opportunistic influenza vaccination in general medical inpatients.

Influenza vaccination is an important preventative health measure in the elderly and those with medical comorbidities. It has been shown to reduce hospitalisations, cardiovascular and respiratory complications. A significant proportion of patients admitted to general medicine are eligible for opportunistic inpatient influenza vaccination. This study explores the cost-effectiveness of such a strategy in reducing subsequent healthcare utilisation costs.

Aetiologies and factors associated with poor clinical outcomes in rhabdomyolysis: a retrospective cohort study in an Australian trauma centre.

Rhabdomyolysis is a clinical syndrome with significant morbidity and mortality that occurs as a result of traumatic and non-traumatic aetiologies. Acute kidney injury, the need for dialysis, and death, can occur due to rhabdomyolysis. This study explores the aetiologies, clinical outcomes and associated factors for poor outcomes in a cohort of patients with rhabdomyolysis in a tertiary trauma centre in Australia.

Progressive multifocal leukoencephalopathy secondary to hepatitis C virus infection-related T-cell lymphopenia.

Progressive multifocal leukoencephalopathy (PML) is an uncommon neurological condition known to occur in the setting of T-cell immune suppression. We report a case of hepatitis C virus (HCV) infection-related T-cell lymphopenia manifesting as PML. HCV treatment and transient viral suppression resulted in immunological recovery with clinical stabilisation.

Opportunities to improve influenza vaccination rates in general medical inpatients.

Influenza vaccination is an important preventative health measure. A significant proportion of general medical inpatients meets indications for annual inactivated influenza vaccination (IIV), as recommended by the Australian National Immunisation Programme. This study explores opportunities to provide IIV to eligible general medical inpatients and associated barriers.

Medication-related anaphylaxis treated in hospital: Agents implicated, patient outcomes, and management lessons.

PURPOSE: On background of increasing medication-related anaphylaxis rates in Australia, our aim was to determine epidemiology, outcomes, adverse drug reaction (ADR) reporting rates, and accuracy of coding in patients treated for nonantimicrobial medication-related anaphylaxis in our hospital network. METHODS: From January 2010 to December 2015 patients treated in our hospital network for medication-related anaphylaxis were identified using International Classification of Diseases, 10th Edition diagnosis code T88.6. Cases were also extracted from the hospital ADR database. Medical records were reviewed to ensure consistent diagnosis and to extract clinical, documentation, and outcome data. RESULTS: Of 1110 patients coded as T88.6, 177 (15.9%) met the medication-related anaphylaxis definition. Eighty (40.8%) had anaphylaxis due to nonantimicrobial agents. Thirteen of these (16.3%) had a previous reaction to the same medication/group. In 51 (63.8%) patients, anaphylaxis occurred during inpatient stay, with 31 reactions occurring during surgery. Eighty-five medications were implicated, most commonly neuromuscular blocking agents (31, 36.5%) and nonsteroidal anti-inflammatory drugs. No trends were noted over the 6-year period, and there was no anaphylaxis-related mortality. Fifty-three (66.3%) patients were assessed in allergy clinics. One in 10 cases did not have the reaction documented in the discharge summary. Adverse drug reaction reports were received for 38 patients (47.5%). CONCLUSIONS: Although acute patient outcomes were excellent, gaps in practice were noted regarding ADR coding accuracy and reporting rates. One in 6 patients had a prior hypersensitivity reaction to a similar medication, so we recommend accurate documentation, ADR review with allergy follow-up, and patient held information to decrease re-exposure risk.

United we stand, divided we conquer: pilot study of multidisciplinary General Medicine Heart Failure Care Program.

BACKGROUND: Heart failure care and education require a multifaceted approach to ensure appropriate transition from inpatient to outpatient care. AIMS: To explore the feasibility of a multidisciplinary heart failure care model, General Medicine Heart Failure Care Program (GM-HFCP), within a General Medical Unit (GMU). METHODS: Prospective non-randomised before-and-after observational quality improvement intervention over a 6-month period was conducted. All consecutive patients admitted to GMU at Alfred Hospital, Melbourne with a diagnosis of acute decompensated heart failure were included. Main outcome measures included changes in rates of pharmacologic prescription, non-pharmacologic ward-based management, patient education and action plan provision after intervention. RESULTS: In total, 108 patients were included (median age 84 (inter-quartile range 80-89) years, 47(44%) females). Significant improvements were noted in non-pharmacologic management for patient education regarding fluid restriction (12-30%, P = 0.04), weight monitoring (10-28%, P = 0.03), heart failure action plan on discharge (4-28%, P = 0.002) and salt restriction (6-32%, P = 0.002). The rates of prescription of heart failure medications remained similar between the pre- and post-implementation periods, particularly in patients with reduced ejection fraction by 'appropriateness of prescription' criteria. There were no differences in inpatient mortality or 30-day readmission rates in both groups. CONCLUSIONS: This prospective observational study demonstrated that it is possible to share the roles of a heart failure nurse amongst members of the multidisciplinary team, with similar rates of delivery of pharmacologic and non-pharmacologic management aspects. However, further innovative improvements are needed to address certain aspects of heart failure care.

Drug-induced liver injury is frequently associated with severe cutaneous adverse drug reactions: experience from two Australian tertiary hospitals.

BACKGROUND: Drug-induced liver injury (DILI) can be associated with certain cutaneous adverse drug reaction (cADR). AIMS: To demonstrate the prevalence of DILI in patients with cADRs. Severity and patterns of liver injury, risk factors, causal medications and outcomes are also examined. METHODS: A retrospective cohort study of patients with cADRs was conducted across two hospitals in Australia. Patients were identified through cross-linkage of multiple databases. RESULTS: One hundred and four patients with cADRs were identified. Of these, 33 (31.7%) had liver injury, representing 50% of patients with drug reaction with eosinophilia and systemic symptoms, and 30.2% of patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). Most cases of liver injury (69.7%) were of a cholestatic/mixed pattern with severe disease in 18.2%. No significant risk factors for development of liver injury were noted, but peripheral lymphocytosis may represent a risk in patients with SJS (odds ratio, OR = 6.0, 95% confidence interval, CI: 1.8-19.7, P = 0.003). Antimicrobials were the most common class to be implicated in DILI. The median length of inpatient stay was longer in patients with liver injury compared to those without (19 vs 11 days, P = 0.002). The mortality rate in those with liver injury was 15.2% and 9.9% in those without. No patients required liver transplantation. CONCLUSIONS: DILI commonly occurs in patients with cADRs and is associated with longer inpatient stay. Patients with SJS/TEN and peripheral lymphocytosis appear to be at higher risk for developing associated liver injury.

Listeria monocytogenes peritonitis in an HIV-infected patient.

We report the first case of Listeria monocytogenes peritoneal dialysis (PD) peritonitis in a human immunodeficiency virus-infected individual successfully treated with intraperitoneal ampicillin, without the need for catheter removal. Suspicion of listerial infection in at-risk individuals is critical as empiric antimicrobial treatment for PD-associated infections may be ineffective against this organism.

More than skin deep. Ten year follow-up of delayed cutaneous adverse drug reactions (CADR).

AIMS: To determine the gaps in practice regarding appropriate ADR documentation and risk communication for patients diagnosed with severe cutaneous adverse drug reactions (CADR). METHODS: This was a retrospective observational cohort study conducted using hospital coding and databases to identify inpatients diagnosed with CADR from January 2004 to August 2014. Hospital discharge summaries, ADR reports and pharmacy dispensing records were reviewed for ADR documentation. Patients still living in Australia and who did not opt out of being contacted were invited to be surveyed by telephone to determine their understanding of recommendations, re-exposure rates and long-term effects. RESULTS: Of 85 patients identified, median age was 59 (IQR 44-72) years and 47.1% were male. The most common diagnosis was TENS (49.4%). Ten patients (11.8%) died as inpatients. Of the 81 patients with a drug-related causality, 47 (58%) had appropriate documentation in all three required medical record platforms. Of the 56 eligible patients, 38 (67.9%) were surveyed; 13% had no information provided upon discharge and 26.3% patients had a mismatch in knowledge of implicated medications. No surveyed patient had a relapse of CADR, but 23.7% had a subsequent unrelated allergic reaction. Thirteen patients (34.2%) reported long-term effects. CONCLUSIONS: We found gaps in the accuracy of ADR documentation and communication of risk at discharge, which indicated risks to patient safety. Electronic systems are being developed to improve documentation. Written information about CADR is being provided at discharge to improve patient understanding and knowledge.

Old but not forgotten: Antibiotic allergies in General Medicine (the AGM Study).

OBJECTIVES: To determine the nature, prevalence and description accuracy of recorded antibiotic allergy labels (AALs) in a cohort of general medical inpatients, and to assess the feasibility of an oral antibiotic re-challenge study. DESIGN: Multicentre cross-sectional study. SETTING AND PARTICIPANTS: All patients admitted to the general medical units of Austin Health and Alfred Health, 18 May - 5 June 2015. MAIN OUTCOME MEASURES: Baseline demographics, medical and allergy history, infection diagnoses and antibiotic prescribing data for general medical inpatients were collected. A questionnaire was administered to clarify AAL history, followed by correlation of responses with electronic and admissions record descriptions. A hypothetical oral re-challenge in a supervised setting was offered to patients with low risk allergy phenotypes (non-immediate reaction, non-severe cutaneous adverse reaction, or unknown reaction more than 10 years ago). RESULTS: Of the 453 inpatients, 107 (24%) had an AAL (median age, 82 years; interquartile range, 74-87 years); 160 individual AALs were recorded, and there was a mismatch in AAL description between recording platforms in 25% of cases. Most patients with an AAL were women (64%; P < 0.001), and more presented with concurrent immunosuppression than those without an AAL (23% v 8%; P < 0.001). ß-Lactam penicillins were employed less frequently in patients with an AAL (16% v 35%; P = 0.02), while ceftriaxone (32% v 20%; P = 0.02) and fluoroquinolones (6% v 2%; P = 0.04) were used more often. Fifty-four per cent of patients with AALs were willing to undergo oral re-challenge, of whom 48% had a low risk allergy phenotype. CONCLUSIONS: AAL prevalence in general medical inpatients was 24%, and was associated with excessive use of broad spectrum antibiotics. Allergies in a large proportion of patients with AALs were incorrectly documented, and were non-immune-mediated and potentially amenable to oral re-challenge. A direct oral re-challenge study in carefully selected patients with low risk allergy phenotypes appears feasible.
