Abstract

fetched live from OpenAlex

ABSTRACTBackground: Pharmacists often overlook drug interaction alerts because of limitations in clinical decision support (CDS) software systems intended to detect evidence-based, clinically significant drug-drug inter-actions (DDIs). Alert fatigue, which occurs when pharmacists become desensitized to an overload of DDIs, may also contribute.Objectives: To gain a better understanding of how pharmacists assess common DDIs and the extent to which computerized drug alerts affect their decision-making, as background for initiatives to overcome alert fatigue and improve detection of DDIs.Methods: This qualitative study used focus group methodology. A structured focus group was planned at each of 3 large tertiary hospitals. Pharmacists were invited to participate if their jobs included patient care and/or dispensary responsibilities. The focus group discussions were audio-recorded and subsequently transcribed, analyzed, and coded into themes using NVivo software. Four main categories of themes were identified: perceived challenges, pharmacists’ assessment of DDIs, barriers to responding to alerts, and proposed solutions.Results: The participants (n = 24) described a large discrepancy among CDS software systems in terms of the severity of specific DDIs, which made it difficult to view these systems as reliable sources. The participants agreed that alert fatigue is present and contributes to DDIs being overlooked. However, lack of patient information to make an initial assessment, as well as the constant need for multitasking, prevents pharmacists from focusing on the evaluation of DDIs. Conclusions: Although alert fatigue was reported to be a common factor responsible for pharmacists missing DDIs, other barriers also exist. Participants suggested ways to limit DDI alerts to those that are clinically relevant. Having a collaborative team of pharmacists periodically review the DDIs embedded in the CDS system, incorporating a colour-code system, and removing duplicate entries were discussed as ways to improve system efficiency.RÉSUMÉContexte : Les pharmaciens ignorent souvent les alertes d’interactions médicamenteuses à cause des limites des logiciels d’aide à la décision clinique (ADC) conçus pour détecter les interactions médicamenteuses (IM) factuelles et significatives d’un point de vue clinique. La fatigue liée aux alarmes (alert fatigue), qui survient lorsque les pharmaciens sont désensibilisés à cause d’une surcharge d’IM, peut aussi contribuer à cette situation.Objectifs : Mieux comprendre comment les pharmaciens évaluent les IM courantes et dans quelle mesure les alertes médicamenteuses affectent leur prise de décision, dans le cadre de la mise en œuvre d’initiatives visant à surmonter la fatigue liée aux alarmes et à mieux détecter les IM.Méthodes : La méthodologie de cette étude qualitative se basait sur les groupes de discussion. Un groupe de discussion structuré était prévu dans chacun des trois grands hôpitaux tertiaires. Les pharmaciens étaient invités à participer si leur travail comprenait des soins offerts aux patients ou des responsabilités dans la distribution de médicaments. Les discussions dans les groupes ont fait l’objet d’un enregistrement audio avant d’être retranscrites, analysées et codées selon les thèmes à l’aide du logiciel NVivo. Quatre catégories de thèmes principaux ont été établies : les défis perçus, l’évaluation des IM par les pharmaciens, les obstacles à lever pour répondre aux alertes et les solutions proposées.Résultats : Les participants (n = 24) ont mentionné un écart important dans les définitions de la gravité [severity] d’IM spécifiques données par les logiciels d’ADC, de sorte qu’il était difficile de se fier à ces systèmes. Les participants ont indiqué que la fatigue liée aux alarmes existait bel et bien et qu’elle contribuait au manque de prise en compte des IM. Cependant, le manque d’information sur les patients pour faire l’évaluation initiale, ainsi que le besoin constant d’effectuer plusieurs tâches à la fois, empêche les pharmaciens de se concentrer sur l’évaluation des IM. Conclusions : Bien que la fatigue liée aux alarmes empêche fréquemment les pharmaciens de remarquer les IM, il existe d’autres obstacles. Les participants ont proposé de limiter les alertes d’IM à celles pertinentes d’un point de vue clinique. Les solutions examinées pour améliorer l’efficacité du système ont porté sur la formation d’une équipe collaborative de pharmaciens qui examine périodiquement les IM intégrés dans le système ADC, l’incorporation d’un système de codes de couleur et l’élimination des entrées dupliquées.

Not 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.
