Objectives: To examine the variation in stated management of acute myocardial infarction (AMI) among clinicians of different specialties, and to compare stated with actual practice.
Design: Mail survey using a hypothetical case history, and review of medical records.
Setting: 47 public hospitals in New South Wales.
Subjects: 224 cardiologists, general/other physicians and general practitioners (GPs) who manage patients with AMI; 390 patients admitted for AMI between February and June 1996.
Outcome Measures: Stated and actual use of treatments and investigations for AMI.
Results: Stated use of aspirin, thrombolysis and beta-blockers (95%-100%, 95%-100% and 80%-86%, respectively) was high in all three specialties. Cardiologists were significantly more likely than GPs to state use of heparin (87% v 57%; P < 0.001), ACE inhibitors (84% v 49%; P < 0.001) and echocardiography or gated pool heart scan (79% v 26%; P < 0.001). Stated use of nitrates by cardiologists was significantly lower compared with the other specialties (29% v 50% and 44%; P = 0.027). Actual use of aspirin was high (> 80%) in all specialties. Actual use of thrombolysis was similar to stated use after adjusting for factors such as time to hospital arrival and ST-segment elevation. There were substantial differences between stated and actual use.
Conclusions: There were differences in practice patterns between and among clinicians of different specialties in NSW, consistent with findings from other countries. The high stated and actual use of aspirin and thrombolysis is encouraging.

Decisions about Medical Treatment and Care, the Legality Assumptions and Sovereign Power - Empowering Patients Out of the State of Bare Life?
J Law Med
November 2024
Menzies Health Institute Queensland, Griffith University, Queensland, Australia.
The framing of patients making decisions about their medical treatment and care as traditional legal decisions, thresholds and formalities is a means to avoid legal liabilities through a rationalisation of decision-making, autonomy and choice. A credible account for the actual place of patients posits the sovereign power (founded in the works of Carl Schmitt and Giorgio Agamben) of the health care professional deciding the state of exception - a discrete legal space where the authority of health care professionals is both lawful and beyond the law. This reveals that dealing with broadly conceived consent issues with more law, more process and procedure but without addressing the inherent legality assumptions that empower health care professionals will always be flawed.

Introduction: COVID-19 has caused tremendous hardships and challenges around the globe. Due to the prevalence of asymptomatic and pre-symptomatic carriers, relying solely on disease testing to screen for infections is not entirely reliable, which may affect the accuracy of predictions about the pandemic trends. This study is dedicated to developing a predictive model aimed at estimating of the dynamics of COVID-19 at an early stage based on wastewater data, to assist in establishing an effective early warning system for disease control.

Internal Medicine, Section of Geriatric Medicine, Amsterdam UMC Location University of Amsterdam, Amsterdam, The Netherlands.
Purpose: Multidisciplinary care pathways for falls prevention, which include falls risk stratification, multifactorial falls risk assessment, and management of multidomain interventions, can reduce falls in older adults. However, efficient multidisciplinary falls prevention care is challenging due to issues such as poor communication and role allocation. This study aimed to identify and visualize the multidisciplinary care needs of primary care-based health care professionals (HCPs) for falls prevention in the Netherlands using the novel co-design approach of journey mapping.

Background: Diversity in the physician workforce is critical for quality patient care. Students from low-income backgrounds represent an increasing proportion of medical school matriculants, yet little research has addressed their medical school experiences.
Objective: To explore the medical school experiences of students from low-income backgrounds using a modified version of Maslow's Hierarchy of Needs (physiologic, safety, love/belonging, esteem, and self-actualization) as a theoretical framework.
