Background In the management of diabetes and high-risk patients, timely treatment with scheduled medicines is critical to prevent severe infections and reduce the risk of lower extremity amputation. However, in Australia, few podiatrists have attained endorsement to prescribe. The aims of this study were to identify the costs associated with developing and implementing a podiatry prescribing mentoring program; and to compare the cost of this program against potential healthcare savings produced. Methods This was a cost-description analysis, involving the calculation of costs associated with the development and implementation of a mentoring program to train podiatrists to become endorsed prescribers. Costs were calculated using the Ingredients Method and examined from the perspective of a public health service provider, and the individual learner podiatrist. Breakeven analysis compared the cost of training a podiatry prescriber for endorsement against the potential benefit (savings) made by averting complications of an infected foot ulcer. A sensitivity analysis was conducted to allow for uncertainty in the results of an economic evaluation. Results Total start-up cost for the podiatry prescriber mentoring program was $13, 251. The total cost to train one learner podiatrist was $30, 087, distributed between the hospital $17, 046 and the individual learner $13, 041. In the setting studied, a podiatry prescriber must avert 0.40 major amputations arising from an infected foot ulcer through prescribing to recover the cost of training. If in-kind training costs are included, total cost increases to $50, 654, and the breakeven point shifts to 0.68 major amputations averted. Conclusion The economic benefits (savings) created by an endorsed prescribing podiatrist over their career in a public health service are likely to outweigh the costs to train a podiatrist to attain endorsement. Further research is required to help understand the effectiveness of podiatry prescribing in reducing diabetic foot related complications and the potential economic impact of podiatry prescribers on this health condition.

Objectives: Plasmid-mediated AmpC beta-lactamases represent a growing clinical concern in Enterobacterales, with challenges in diagnostic approaches, limited data on clinical outcomes, and our incomplete understanding of their regulatory mechanisms warranting the need for further investigation. Methods: This retrospective study examined the genomic and clinical characteristics of cefoxitin-non-susceptible, ceftriaxone-susceptible Escherichia coli and Klebsiella pneumoniae bloodstream isolates collected from a tertiary hospital in Singapore. Whole-genome sequencing was performed to detect ampC genes, subtypes, and associated regulatory elements. Results: Among 108 cefoxitin-non-susceptible isolates, only 15 (13.9%) harboured plasmid-mediated ampC, suggesting that cefoxitin non-susceptibility alone in ceftriaxone susceptible isolates was not predictive of ampC carriage. All plasmid-ampC isolates were from the blaDHA-1 subtype and carried ampR, a known transcriptional regulator of inducible beta-lactamase expression. Notably, five non-ampC carrying Klebsiella isolates displayed truncations in ompK35 and ompK36, which could potentially contribute to reduced cefoxitin susceptibility via porin loss. Conclusions: These findings underscore the limited diagnostic utility of cefoxitin susceptibility testing for detecting plasmid-mediated ampC producers and highlight the clinical relevance of regulatory genes such as ampR in mediating inducible resistance. The routine incorporation of molecular diagnostics or genome sequencing may be necessary to improve detection accuracy and inform antimicrobial stewardship strategies.

Blended learning describes a combination of teaching methods, often utilizing digital technologies. Research suggests that learner outcomes can be improved through some blended learning formats. However, the cost-effectiveness of delivering blended learning is unclear. This study aimed to determine the cost-effectiveness of a face-to-face learning and blended learning approach for evidence-based medicine training within a medical program. The economic evaluation was conducted as part of a randomized controlled trial (RCT) comparing the evidence-based medicine (EBM) competency of medical students who participated in two different modes of education delivery. In the traditional face-to-face method, students received ten 2-hour classes. In the blended learning approach, students received the same total face-to-face hours but with different activities and additional online and mobile learning. Online activities utilized YouTube and a library guide indexing electronic databases, guides, and books. Mobile learning involved self-directed interactions with patients in their regular clinical placements. The attribution and differentiation of costs between the interventions within the RCT was measured in conjunction with measured outcomes of effectiveness. An incremental cost-effectiveness ratio was calculated comparing the ongoing operation costs of each method with the level of EBM proficiency achieved. Present value analysis was used to calculate the break-even point considering the transition cost and the difference in ongoing operation cost. The incremental cost-effectiveness ratio indicated that it costs 24% less to educate a student to the same level of EBM competency via the blended learning approach used in the study, when excluding transition costs. The sunk cost of approximately AUD $40,000 to transition to the blended model exceeds any savings from using the approach within the first year of its implementation; however, a break-even point is achieved within its third iteration and relative savings in the subsequent years. The sensitivity analysis indicates that approaches with higher transition costs, or staffing requirements over that of a traditional method, are likely to result in negative value propositions. Under the study conditions, a blended learning approach was more cost-effective to operate and resulted in improved value for the institution after the third year iteration, when compared to the traditional face-to-face model. The wider applicability of the findings are dependent on the type of blended learning utilized, staffing expertise, and educational context.

Student clinics are generally more costly, from a university perspective, compared with placements in public health services.2 Forbes et al. report using casually employed clinical educators to provide clinical education and support.1 Based on the University of Queensland Enterprise Agreement, a conservative estimate of clinical educator cost is $AU4S per educator hour,3 with additional costs arising related to equipment, facilities, and support staff.4 In comparison, Victorian universities are charged a maximum of $AU57.15 per student day for allied health student placements by the host health services.5 Note that there is currently no standardised fee schedule in Queensland,6 which, according to supply and demand economic theory, should lead to an increase in the cost of placements to universities given the paucity of placement supply relative to demand. Governments are primarily focused on meeting the healthcare needs of the public, through ensuring adequate supply of workforce and delivery of quality health care, particularly for primary care and publicly funded health services. [...]if universities wish to make the case for sustained government funding for student clinics, these clinics must be designed for and demonstrate flow-on benefit to training and workforce pipelines, as well as providing care that is integrated with the wider healthcare system. When done well, student clinics can provide a valuable service to the community, often aimed at addressing vulnerable or disadvantaged patient populations, potentially reducing burden on other health services.9 Advancing health workforce development through financially sustainable student clinics requires a balanced focus on strong educational design and innovative funding mechanisms, ensuring that they meet the needs of students, universities, governments, and most importantly - patients.

Background Severely obese type 2 diabetics who undergo Roux-en Y gastric bypass surgery have significant improvements in glycaemic control. Little work has been undertaken to establish the independent predictors of such resolution or to develop a predictive model. The aim of this study was to develop a mathematical model and establish independent predictors for the resolution of diabetes. Methods A consecutive sample of 130 severely obese type 2 diabetics who underwent gastric bypass surgery for weight loss from November 1997 to May 2007 with prospective pre-operative documentation of biochemical and clinical measurements was followed up over 12 months. Logistic discrimination analysis was undertaken to identify those variables with independent predictive value and to develop a predictive model for resolution of type 2 diabetes. Consecutive samples of 130 patients with body mass index (BMI) ≥ 35 with type 2 diabetes were selected. One hundred and twenty-seven patients completed the study with a sufficient data set. Patients were deemed unresolved if (1) diabetic medication was still required after surgery; (2) if fasting plasma glucose (FPG) remained >7 mmol/L; or (3) HbA1c remained >7%. Results Resolution of diabetes was seen in 84%, while diabetes remained but was improved in 16% of patients. Resolution was rapid and sustained with 74% of those on medication before surgery being able to discontinue this by the time of discharge 6 days following surgery. Five pre-operative variables were found to have independent predictive value for resolution of diabetes, including BMI, HbA1c, FPG, hypertension and requirement for insulin. Two models have been proposed for prediction of diabetes resolution, each with 86% correct classification in this cohort of patients. Conclusions Type 2 diabetes resolves in a very high percentage of patients undergoing gastric bypass surgery for severe obesity. The key predictive variables include pre-operative BMI, HbA1c, FPG, the presence of hypertension and diabetic status.

Bryant’s sign is defined as ecchymosis at the base of the penis and scrotum and is usually associated with a retroperitoneal bleed or ruptured aortic aneurysm. We report the case of a retroperitoneal paraduodenal bleed which presented with Bryant’s sign. Imaging confirmed a pancreaticoduodenal arcade microaneurysm and associated low-grade coeliac artery stenosis (Sutton-Kadir syndrome). Retroperitoneal bleeding can be life threatening and requires prompt diagnosis and management. However, diagnosis can be challenging due to the clinical variation in presentation. The rarity of presentation in this case caused significant uncertainty necessitating a multidisciplinary approach for diagnostic clarity and safe patient care.

A 49-year-old man presented to the nearest emergency department profoundly septic with significantly raised inflammatory markers. He had a background of floor of mouth invasive squamous cell carcinoma for which he underwent complex head and neck surgery followed by adjuvant radiotherapy and insertion of a percutaneous gastrostomy tube for feeding. He experienced 3 weeks of retching, cough and malaise. Imaging revealed both an oesophageal perforation and perforated duodenal ulcer, presumed secondary to oesophageal stricturing from his prior surgery and radiotherapy.

Introduction We sought to evaluate the reporting and methodological quality of cost evaluations of physician continuing professional development (CPD). Methods We conducted a systematic review, searching MEDLINE, Embase, PsycInfo, and the Cochrane Database for studies comparing the cost of physician CPD (last update 23 April 2020). Two reviewers, working independently, screened all articles for inclusion. Two reviewers extracted information on reporting quality using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS), and on methodological quality using the Medical Education Research Study Quality Instrument (MERSQI) and a published reference case. Results Of 3338 potentially eligible studies, 62 were included. Operational definitions of methodological and reporting quality elements were iteratively revised. Articles reported mean (SD) 43% (20%) of CHEERS elements for the Title/Abstract, 56% (34%) for Introduction, 66% (19%) for Methods, 61% (17%) for Results, and 66% (30%) for Discussion, with overall reporting index 292 (83) (maximum 500). Valuation methods were reported infrequently (resource selection 10 of 62 [16%], resource quantitation 10 [16%], pricing 26 [42%]), as were descriptions/discussion of the physicians trained (42 [68%]), training setting (42 [68%]), training intervention (40 [65%]), sensitivity analyses of uncertainty (9 [15%]), and generalizability (30 [48%]). MERSQI scores ranged from 6.0 to 16.0 (mean 11.2 [2.4]). Changes over time in reporting index (initial 241 [105], final 321 [52]) and MERSQI scores (initial 9.8 [2.7], final 11.9 [1.9]) were not statistically significant ( p  ≥ 0.08). Discussion Methods and reporting of HPE cost evaluations fall short of current standards. Gaps exist in the valuation, analysis, and contextualization of cost outcomes.

Long-term or residential services are designed to support older people who experience challenges to their physical and mental health. These services play an important role in the health and well-being of older adults who are more susceptible to problems such as malnutrition. Estimates of the significance of malnutrition require up-to-date prevalence data to inform government strategies and regulation, but these data are not currently available in Australia. The aim of this study was to collect malnutrition prevalence data on a large sample of people living in residential aged care facilities in Australia. A secondary aim was to examine the relationship between malnutrition and anthropometry (body mass index (BMI) and weight loss). This prevalence study utilised baseline data collected as part of a longitudinal study of malnutrition in 10 Residential Aged Care facilities across three states in Australia (New South Wales, South Australia, and Queensland). The malnutrition status of eligible residents was assessed by dietitians and trained student dietitians using the Subjective Global Assessment (SGA) with residents categorised into SGA-A = well nourished, SGA-B = mildly/moderately malnourished, and SGA-C = severely malnourished. Other data were extracted from the electronic record. Of the 833 listed residents, 711 residents were eligible and had sufficient data to be included in the analysis. Residents were predominantly female (63%) with a mean (SD) age of 84 (8.36) years and a mean (SD) BMI of 26.74 (6.59) kg/m2. A total of 40% of residents were categorised as malnourished with 34% (n = 241) categorised as SGA-B, and 6% (n = 42) SGA-C. Compared to the SGA, BMI and weight loss categorisation of malnutrition demonstrated low sensitivity and high specificity. These findings provide recent, valid data on malnutrition prevalence and highlight the limitations of current Australian practices that rely on anthropometric measures that under-detect malnutrition. There is an urgent need to implement a feasible aged care resident screening program to address the highly prevalent condition of malnutrition in Australia.
