Barriers to and Facilitators of Delabelling of Antimicrobial Allergies: A Qualitative Meta-synthesis.

Background: Patients who report penicillin allergies may receive alternative antibiotics. Such substitution contributes to antimicrobial resistance, lower treatment efficacy, increased frequency of adverse events, and increased costs. Approximately 90% of individuals who report a penicillin allergy can tolerate a penicillin. Objective: To identify the barriers to and facilitators of removal by health care workers of inaccurate antimicrobial allergies from patient records, known as delabelling. Data Sources: The MEDLINE database was searched from inception to December 29, 2020. Study Selection and Data Extraction: Qualitative studies evaluating health care professionals' perceptions of barriers to and/or facilitators of the act of delabelling a patient's antimicrobial allergies were included in the meta-synthesis. Data Synthesis: The Theoretical Domains Framework was used to code and group individual utterances from the included studies, which were mapped to the Behaviour Change Wheel and corresponding intervention function and policy categories. Results: Four studies met the inclusion criteria. Eight themes were identified as representing barriers to delabelling: delabelling skills, patient education skills, knowledge, electronic health records (EHRs), communication frameworks, time, fear about allergic reactions, and professional roles. Behaviour change interventions that may overcome these barriers include education, training, algorithms and toolkits, changes to EHRs, use of dedicated personnel, policies, incentivization of correct labelling, and an audit system. Conclusions: Eight themes were identified as barriers to delabelling of antimicrobial allergies. Future behaviour change interventions to address these barriers were proposed. Confidence in the findings of this study was judged to be moderate, according to the GRADE CERQual approach.

Contexte: Les patients qui signalent des allergies à la pénicilline peuvent recevoir d'autres antibiotiques. Une telle substitution contribue à la résistance aux antimicrobiens, à une moindre efficacité du traitement, à une fréquence accrue des événements indésirables et à une augmentation des coûts. Environ 90 % des personnes qui déclarent une allergie à la pénicilline peuvent la tolérer. Objectif: Identifier les obstacles à l'élimination par les travailleurs de la santé des allergies antimicrobiennes inexactes des dossiers des patients, ce que l'on appelle « le désétiquetage ¼, et les facteurs qui le favorisent. Sources des données: La base de données MEDLINE a été consultée depuis sa création jusqu'au 29 décembre 2020. Sélection de l'étude et extraction des données: Des études qualitatives évaluant les perceptions des professionnels de la santé quant aux obstacles à l'acte de désétiquetage des allergies aux antimicrobiens d'un patient et les facilitateurs de celui-ci ont été incluses dans la métasynthèse. Synthèse des données: Le cadre théorique des domaines a été utilisé pour coder et regrouper les énoncés individuels, qui ont ensuite été associés à la roue du changement de comportement ainsi qu'aux catégories de fonctions et de politiques d'intervention correspondantes. Résultats: Quatre études répondaient aux critères d'inclusion. Huit thèmes ont été identifiés comme représentant des obstacles au désétiquetage: les compétences en la matière, les compétences en matière d'éducation des patients, les connaissances, les dossiers de santé électroniques (DSE), les cadres de communication, le temps, la peur des réactions allergiques et les rôles professionnels. Les interventions visant le changement de comportement qui peuvent surmonter ces obstacles comprennent l'éducation, la formation, les algorithmes et les boîtes à outils de désétiquetage, la modification des DSE, le recours à du personnel dédié, des politiques, l'incitation à un étiquetage correct et un système d'audit. Conclusions: Huit thèmes ont été identifiés comme étant des obstacles au désétiquetage des allergies aux antimicrobiens. De futures interventions ciblant le changement de comportement pour les surmonter ont été proposées. La confiance dans les résultats de cette étude a été jugée modérée, selon l'approche GRADE CERQual.

Does Point-of-Care Testing Impact Length of Stay in Emergency Departments (EDs)?: A Before and After Study of 26 Rural and Remote EDs.

The implementation of Point-of-Care Testing (PoCT) services across rural and remote emergency departments (EDs) by NSW Health Pathology has the potential to significantly improve timely access to results for certain types of pathology laboratory tests and help to deliver timely patient care. The aim of this study was to examine the impact of the implementation of PoCT on the length of stay (LOS) of patients in rural and remote EDs. A total of 3808 patients with a circulatory system illness were treated and discharged at any one of 22 rural and remote EDs during the study period. Generalised Estimating Equation (GEE) modelling was applied to examine whether the implementation of PoCT impacted the ED LOS with adjustment for a range of clinical variables. More patients were treated and discharged from these rural and remote EDs within 4-hours after the PoCT implementation (post-PoCT 86.8% versus pre-PoCT 84.3%). Although average ED LOS was 11 minutes shorter in the post-PoCT period, the impact of PoCT on ED LOS was not conclusive after considering other important clinical factors (p=0.07). This study is the one of the few to examine changes in LOS following the introduction of PoCT in EDs in Australia. The study also identified areas where more robust methods could be applied in the future as the quality of PoCT data improves to further assess the potential effects of this technology on practice and outcomes.

Point-of-Care Testing Across Rural and Remote Emergency Departments in Australia: Staff Perceptions of Operational Impact.

New South Wales (NSW) Health Pathology is implementing one of the world's largest managed PoCT services across rural and remote Emergency Departments (EDs) in New South Wales, Australia to improve patient access to care. The aim of this qualitative study was to gain a context-rich understanding of the operational impact of the NSW rollout of PoCT across rural and remote ED settings as experienced by frontline clinical staff. Clinical professionals (n=14) participated in interviews and focus groups in August 2015 at four rural and remote NSW EDs. Participants perceived that PoCT provided greater access to pathology thus facilitating more efficient and effective patient care via faster test turnaround and time to treatment and more effective decisions about the need to transfer patients to appropriate sites when required. These factors have a potentially important role in saving lives. Staff also identified innovative and disruptive challenges to clinical work patterns associated with PoCT implementation, particularly in relation to work flows, resource allocation and the governance arrangements.

Assessing Data Integration and Quality for the Evaluation of Point-of-Care Testing Across Rural and Remote Emergency Departments in Australia.

In Australia, New South Wales Health Pathology's implementation of managed Point-of-Care Testing (PoCT) services across rural and remote emergency departments (EDs) has the potential to significantly improve access to results for certain types of pathology laboratory tests and help to deliver timely patient care. The aim of this study was to assess the quality of the datasets, including the integration of PoCT results into clinical systems, as a precursor to the application of an evaluation framework for monitoring the delivery of PoCT services and their impact on patient care. Three datasets, including laboratory, ED presentations and hospital admissions data were extracted from the relevant clinical information systems. Each dataset was assessed on six dimensions: completeness, uniqueness, timeliness, validity, accuracy, and consistency. Data incompleteness was the largest problem. Assessing the PoCT data integration and data quality is a precondition for the evaluation of PoCT and for monitoring and improving service delivery.
