Background:
Paramedics are frequently required to make rapid decisions in an uncontrolled, dynamic environment, often with limited diagnostic information. In Ontario, paramedic practice is based on a set of provincial medical directives that provide diagnostic and treatment criteria. Unsupervised deviation from these directives is classified as a form of error and highly discouraged. To date, there is little known about how years of clinical experience or level of certification affect the way these medical directives are used. The purpose of this study was to examine the relationship between paramedic experience, training and accuracy of treatment decisions when faced with patients who meet and fall outside of the existing medical directives.
Methods:
Thirty-one participants (16 experienced / 15 novice) were recruited from two paramedic services in Ontario. “Experienced” was defined as in-practice for 5 years or more. Participants were presented with 9 scenarios; in 6 scenarios, the patient presentation fit within the existing directives, while in 3 scenarios, the patient presentation fell outside the medical directives. Multiple-choice responses were used to capture participants’ decisions to treat or not treat the patients. Responses were scored and submitted to a mixed-factorial ANOVA to evaluate differences in accuracy between case types, years of experience and level of training.
Results:
There was a significant effect of case type (p < 0.004). Accuracy was lower when the patient presentation did not meet the criteria of the medical directive (76.34% (CI = 67.15% to 85.53%) vs. 98.35% (CI = 96.55% to 100%) when they did. There was no effect of years of clinical practice or level of certification.
Conclusion:
The results suggest both novice and experienced paramedics are able to accurately apply medical directives, however, there is a significant decrease in accuracy when the patient presentation does not fit one. This variation in practice may have a significant impact on patient safety, and further research is required to determine what factors may be causing this decreased accuracy. / Thesis / Master of Science (MSc) / Paramedics work in a fast-paced, dynamic environment. The types of patients, and the situations paramedics encounter are different every day. Paramedic practice is based on a series of provincial medical directives that outline the different proceedures, medications and types of patients that can be treated. While these directives cover many of the cases paramedics encounter, there will always be cases that don’t “fit”. The purose of this study is to see if paramedics approach those types of cases in a different way, and if their years of experience or level of training change how good they are at idenfiying what patients require treatment. As there is very little paramedic specific research on this topic, this study will serve as a starting point for future research and hopefully stimulate discussion about paramedic practice, and how to support paramedics getting better at their jobs.
