Positive and Negative Impacts of a Continuing Professional Development Intervention on Pharmacist Practice
Bibliographic record
Abstract
INTRODUCTION: Evaluations of behavior change interventions aimed at improving professional practice are increasingly focused on impacts at the practice and patient outcome levels. Many of these evaluations assume that if the intended changes occur, the result represents an improvement. However, given the systemic nature of clinical practice, a change in one area can produce changes in other areas as well, some of which may adversely affect the patient. Balancing measures are used to determine whether unintended consequences of an intervention have been introduced into other areas of the system. The aims of this study were to evaluate the impact of behavior change intervention-based continuing professional development (CPD) on pharmacist interventions (resolution of drug therapy problems-DTPs) and resolution of quality indicator DTPs and knowledge change for urinary tract infections (UTI) and pneumonia. As a balancing measure, we aimed to determine whether delivery of behavior change interventions targeting pneumonia and UTI practice results in a negative impact on other important pharmacist interventions, specifically the resolution of heart failure DTPs. METHODS: A quasiexperimental study was conducted at a Canadian health authority that evaluated the impacts of an 8-week multifaceted behavior change intervention delivered to 58 ward-based pharmacists. The primary outcome was change in proportion of UTI and pneumonia DTPs resolved from the 6-month preintervention to 6-month postintervention phase. Secondary outcomes were changes in proportion of UTI and pneumonia quality indicator DTPs resolved, knowledge quiz scores, and proportion of quality indicator DTPs resolved for heart failure as a balancing measure. RESULTS: A total of 58 pharmacists were targets of the intervention. The proportion of resolved UTI and pneumonia DTPs increased from 17.8 to 27.2% (relative risk increase 52.8%, 95% confidence interval [CI] 42.8-63.6%; P < 0.05). The proportion of resolved UTI and pneumonia quality indicator DTPs increased from 12.2% to 18.2% (relative risk increase 49.9%, 95% CI 34.5-67.0%; P < 0.05). Resolved heart failure DTPs decreased from 14.3 to 8.5% (RRR 40.4%, 95% CI 33.9-46.2%; P < 0.05). Thirty-six pharmacists completed the pre- and post-quiz. Scores increased from 11.3/20 ± 3.2/20 to 14.8/20 ± 2.9/20 (P < 0.05). DISCUSSION: CPD using a multifaceted behavior change intervention improved pharmacist behavior and knowledge for UTI and pneumonia. However, these improvements may be offset by reduced interventions for other disease states, such as heart failure. Strategies to mitigate the unintended effects on other professional behaviors should be implemented when delivering CPD focused on changing one aspect of professional behavior.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
