A comparative study on the clinical decision-making processes of nurse practitioners vs. medical doctors using...

To investigate the decision-making skills of secondary care nurse practitioners compared with those of medical doctors.

A literature review was conducted, searching for articles published from 1990 - 2012. The review found that nurse practitioners are key to the modernization of the National Health Service. Studies have shown that compared with doctors, nurse practitioners can be efficient and cost-effective in consultations.

Qualitative research design.

The information processing theory and think aloud approach were used to understand the cognitive processes of 10 participants (5 doctors and 5 nurse practitioners). One nurse practitioner was paired with one doctor from the same speciality and they were compared using a structured scenario-based interview. To ensure that all critical and relevant cues were covered by the individual participating in the scenario, a reference model was used to measure the degree of successful diagnosis, management and treatment. This study was conducted from May 2012 - January 2013.

The data were processed for 5 months, from July to November 2012. The two groups of practitioners differed in the number of cue acquisitions obtained in the scenarios. In our study, nurse practitioners took 3 minutes longer to complete the scenarios.

This study suggests that nurse practitioner consultations are comparable to those of medical doctors in a secondary care environment in terms of correct diagnoses and therapeutic treatments. The information processing theory highlighted that both groups of professionals had similar models for decision-making processes.
