Emergency medicine and "acute" general practice: comparing apples with oranges.

Emergency Departments (EDs) operate at the interface between the inpatient and ambulatory sectors of health care. Because of shared funding between the Commonwealth and States for ambulatory care, there has been intense focus on the ED patient population, and the potential to shift the locus of care for non-inpatients. One of the frequently cited models for the provision of after-hours GP services is the Balmain General Practice Casualty (GPC). This paper analyses the GPC model, looking in detail at casemix, clinical quality, waiting times and cost-effectiveness. It is argued that the services provided and the casemix of the patient population of GPC and EDs are distinctly different. Cost-effectiveness for GPC has not been objectively established. Health service planning should recognise the distinct but complementary roles of general practice and emergency medicine. Evaluation of alternative models of service provision should critically examine the available evidence, and comparisons should be based on a precise analysis of equivalent services.

Is there equity in emergency medical care? Waiting times and walk-outs in South Western Sydney hospital emergency departments.

This study explores the association between selected socioeconomic characteristics of emergency patients with waiting times in emergency departments and walk-outs (those who did not wait for treatment) in South Western Sydney Area Health Service hospital emergency departments. Bivariate and multivariate analyses indicated that waiting times to see a doctor and walk-out rates varied by age, sex, country of birth, insurance status, socioeconomic status, severity of patient illness and day of arrival. Patients who were female, from a non-English-speaking background, self-referred, uninsured and those from lower socioeconomic status showed significantly longer waiting times than others. Patients who left emergency departments without treatment showed higher waiting times from arrival to triage than other groups. This applied across socioeconomic categories. These findings indicate that prolonged waiting times for triage, which occur at the busiest periods, may be one of the main indicators for patients leaving emergency departments without treatment. The study also demonstrates variability in waiting times, which could possibly be partly addressed by more standardised triage policies, but may be influenced by other non-clinical factors, which require further investigation.

Evaluation of the prevalence of drug and alcohol abuse in motor vehicle trauma in south western Sydney.

This study estimated prospectively the prevalence of high drug and alcohol levels in road trauma cases who met the criteria for activation of the Liverpool Hospital's trauma team. Urine analysis of road trauma victims between October 1992 and October 1993 was undertaken for drug and alcohol estimation. A total of 164 drivers were studied. A urine alcohol concentration (UAC) exceeding 0.08 g/dL was detected in 27 drivers (16.5%). Cannabinoids were detected in the urine of 25 drivers (15.2%), in 17 the concentrations exceeded 400 ng/mL. In one instance amphetamine, cocaine and heroin were detected in the same injured driver. Combined use of alcohol with some other drugs was detected in only four drivers. Alcohol and cannabinoid levels were prevalent in the urine of injured drivers in this study, particularly in young males who remain over-represented in the group of injured drivers. In the population surveyed other drugs were rarely detected. The role of cannabinoids in road trauma and the use of cannabinoids in young male drivers will however need to be monitored more extensively.
