Randomized Controlled Trial Comparative Study Clinical Trial
Effectiveness of an adult-learning, self-directed model compared with traditional lecture-based teaching methods in out-of-hospital training.
Until recently, the U.S. Army Combat Medic School used a traditional teaching model with heavy emphasis on large group lectures. Skills were taught separately with minimal links to didactics. ⋯ In this study setting, an adult-learning model offers only a modest improvement in cognitive evaluation scores over traditional teaching when measured at the end of the course. Additionally, students in the traditional teaching model assess themselves as proficient more frequently than instructors, whereas instructor and student perception of proficiency more closely matched in the adult-learning model.

No single universal definition of emergency department (ED) overcrowding exists. The authors hypothesize that a previously developed site-sampling form for academic ED overcrowding is a valid model to quantify overcrowding in academic institutions and can be used to develop a validated short form that correlates with overcrowding. ⋯ Overcrowding varied widely between academic centers during the study period. Results of a five-question reduced model are valid and accurate in predicting the degree of overcrowding in academic centers.

Comparative Study
Customer satisfaction in a large urban fire department emergency medical services system.
The purpose of this study was to determine if emergency medical services (EMS) customer satisfaction could be assessed using telephone-survey methods. The process by which customer satisfaction with the EMS service in a large, fire department-based EMS system is reported, and five month results are presented. ⋯ It is possible to conduct a survey of EMS customer satisfaction using telephone-survey methods. Although difficulties exist in contacting patients, useful information is made available with this method. Such surveys should be an integral part of any EMS system's quality-improvement efforts. In this survey, the overwhelming majority of patients, both transported and not transported, were satisfied with their encounter with EMS.

The applications of simple linear regression in medical research are limited, because in most situations, there are multiple relevant predictor variables. Univariate statistical techniques such as simple linear regression use a single predictor variable, and they often may be mathematically correct but clinically misleading. Multiple linear regression is a mathematical technique used to model the relationship between multiple independent predictor variables and a single dependent outcome variable. ⋯ Examples from the first article in this series are expanded on using a primarily graphic, rather than mathematical, approach. The importance of the relationships among the predictor variables and the dependence of the multivariate model coefficients on the choice of these variables are stressed. Finally, concepts in regression model building are discussed.
