Patterns of use of emergency medical transport: A population-based study

The objective of this study was to characterize population-based emergency medical service (EMS) use rates and examine some of the factors associated with usage of prehospital services. The design was a population-based observational study with multiple regression analysis. Transports reported by prehospital services to the Kentucky Emergency Medical Services Information System from Kentucky counties in which all EMS units submit computerized data was the data source. There were 102,321 emergent transports reported. The overall rate of use of EMS transports was 51.7 ± 24.1/1,000/year, but the rate varied between different communities (range 11 to 139/1,000/year). Rate of use was highest in those older than 65 (178.5 ± 84.2/1,000/year), with the rate increasing expoentially with increasing age in this age group. Reasons for transport were age dependent. There was an association between increasing poverty level and use of EMS. In addition, the absence of 911 service (odds ratio [OR] 1.18, 95% confidence interval [CI; 1.14, 1.22]) and the absence of a hospital in the county (OR 1.27, 95% CI [1.24, 1.30]) were also associated with increasing rates of ambulance use. Rates of use of EMS are most dependent on age and cause, but use is also correlated with increasing levels of poverty. Wide variations in use between communities suggests that point estimates using one community may over- or underestimate EMS usage.

Vancomycin and teicoplanin use in Victorian hospitals. The Victorian Drug Usage Evaluation Group.

To determine patterns of prescribing of glycopeptide antibiotics (vancomycin and teicoplanin) in Victorian hospitals and identify areas for targeted intervention. A concurrent, observational, multisite evaluation of drug use. Thirty-five Victorian hospitals, 1-14 September 1997. Patients commencing a glycopeptide antibiotic course. Rate of glycopeptide antibiotic use; indications; duration of use; main hospitals using glycopeptide antibiotics. 293 patients (269 adults and 24 neonates) commenced on 302 glycopeptide antibiotic courses: 296 intravenous (i.v.) vancomycin courses and three each of oral vancomycin and parenteral teicoplanin. The overall rate of use was 10.3 courses per 1000 inpatient separations. Of 271 i.v. vancomycin courses for adults, 176 (65%) were for treatment--120 empirically. The median duration of treatment courses was 4.7 days (interquartile range, 2.0-8.2 days). A flucloxacillin-resistant organism was confirmed for 44% of treatment courses. Ninety-five i.v. vancomycin courses were for prophylaxis, including for cardiac (54%) and vascular surgery (21%); 82% of prophylactic courses were administered for less than 24 hours. Of all the glycopeptide antibiotic courses, 69% were administered at five major metropolitan hospitals. Glycopeptide antibiotic use in Victoria is concentrated in the major metropolitan hospitals. Prolonged durations of vancomycin therapy, including for surgical prophylaxis and empirical therapy not subsequently confirmed by microbiology findings, would be suitable targets for interventional strategies.

An assessment of the potential for repatriating care from urban to rural Manitoba.

Following the closure of Manitoba hospital beds, the Manitoba government adopted a strategy of shifting hospital care from more expensive urban hospitals to less expensive rural facilities. With this project, Manitoba Centre for Health Policy and Evaluation (MCHPE) studied the implications of the stated policy of "repatriation." The project first involved examining population-based patterns of hospital utilization to define hospital service areas for 10 large rural hospitals. Three different hospital service area definitions were developed for use in sensitivity testing. Rates of overall use of hospital services, indicators of need for health care, and patterns of use of urban facilities are compared for these hospital service areas. Using a large rural hospital as a benchmark, patterns of adult surgical, adult medical, pediatric, and obstetric care were examined for the hospital service areas. Number and percent of cases provided by the index hospital and by urban hospitals were compared, to assess the feasibility and the potential impact of redirection of care to the benchmark level. Although in theory a significant percentage of care delivered to rural residents by Winnipeg hospitals might be redirected to rural institutions, the project raised issues of feasibility. Moreover, it identified that most of the redirected cases could be accommodated within existing capacity.
