Ushering in Antifungal Stewardship: Perspectives of the Hematology Multidisciplinary Team Navigating Competing Demands, Constraints, and Uncertainty.

ABSTRACT: Background:The social, contextual, and behavioral determinants that influence care in patients at risk for invasive fungal diseases (IFD) are poorly understood. This knowledge gap is a barrier to the implementation of emerging antifungal stewardship (AFS) programs. We aimed to understand the barriers and enablers to AFS, opportunities for improvement, and perspectives of AFS for hematology patients at a major medical center in Australia. Methods:Semistructured, face-to-face interviews were conducted with 35 clinicians from 6 specialties (hematology, infectious diseases, pharmacy, nursing, radiology, respiratory), followed by thematic analysis mapped to a behavioral change framework. Results:Access to fungal diagnostics including bronchoscopy was identified as the key barrier to rational prescribing. Collective decision making was the norm, aided by an embedded stewardship model with on-demand access to infectious diseases expertise. Poor self-efficacy/knowledge among prescribers was actually an enabler of AFS, because clinicians willingly deferred to infectious diseases for advice. A growing outpatient population characterized by frequent care transitions was seen as an opportunity for AFS but neglected by an inpatient focused model, as was keeping pace with emerging fungal risks. Ad hoc surveillance, audit, and feedback practices frustrated population-level quality improvement for all actors. Antifungal stewardship was perceived as a specialized area that should be integrated within antimicrobial stewardship but aligned with the cultural expectations of hematologists. Conclusions:Antifungal stewardship is multifaceted, with fungal diagnostics a critical gap and outpatients a neglected area. Formal surveillance, audit, and feedback mechanisms are essential for population-level quality improvement. Resourcing is the next challenge because complex immunocompromised patients require personalized attention and audit of clinical outcomes including IFD is difficult.

Project description:Multidisciplinary team meetings are a current international practice in cancer care, but to date, few data exist on the specificity of its practice in hematology.In this manuscript, we present the result of the first national study, realized with quantitative and qualitative methods in France, which brings new insights in order to improve the collegial decision-making process.To improve the effectiveness of MDTMs, the needs to focus on complex cases, to enhance patient centeredness and teamwork are relevant aspects, and a specific focus on hematological particularities is warranted to truly improve process.Background Understanding the Multidisciplinary team meetings (MDTMs) process in different medical specialties facilitates the identification of core factors supporting effective MDTM work. Our mixed-methods study explores the participants' perceptions of hematology MDTMs.Design Online questionnaires collected data concerning the decision-making process, benefits and inconveniences of MDTMs for both patients and professionals. Semi-directive phone interviews were conducted and analyzed, thereby supplying qualitative data.Results A total of 205 professionals responded to the questionnaire and 22 participated in the qualitative interviews. The data indicate the unique characteristics of hematology, including a specific definition of collegiality, the frequent solicitation of expert advice and the anticipation of treatment even prior to the occurrence of MDTMs. Additional information concerning patients' wishes and psychosocial conditions are also needed. Participants emphasize the subjective aspects and the impact of the climate of MDTMs on medical decisions.Conclusion Although MDTMs are recognized to be a valuable tool, organizational and relational issues may interfere with their efficiency.To improve the effectiveness of MDTMs, the needs to focus on complex cases, to enhance patient centeredness and teamwork are relevant aspects. A specific focus on hematological particularities might be warranted to truly improve the collegial decision-making process in the context of hematology.

Project description:Abstract Background ICUs are settings of high antifungal consumption. There are few data on prescribing practices in ICUs to guide antifungal stewardship implementation in this setting. Methods An antifungal therapy (AFT) service evaluation (15 May–19 November 2019) across ICUs at three London hospitals, evaluating consumption, prescribing rationale, post-prescription review, de-escalation and final invasive fungal infection (IFI) diagnostic classification. Results Overall, 6.4% of ICU admissions (305/4781) received AFT, accounting for 11.41 days of therapy/100 occupied bed days (DOT/100 OBD). The dominant prescribing mode was empirical (41% of consumption), followed by targeted (22%), prophylaxis (18%), pre-emptive (12%) and non-invasive (7%). Echinocandins were the most commonly prescribed drug class (4.59 DOT/100 OBD). In total, 217 patients received AFT for suspected or confirmed IFI; 12%, 10% and 23% were classified as possible, probable or proven IFI, respectively. Hence, in 55%, IFI was unlikely. Proven IFI (n = 50) was mostly invasive candidiasis (92%), of which 48% had been initiated on AFT empirically before yeast identification. Where on-site (1 → 3)-β-d-glucan (BDG) testing was available (1 day turnaround), in those with suspected but unproven invasive candidiasis, median (IQR) AFT duration was 10 (7–15) days with a positive BDG (≥80 pg/mL) versus 8 (5–9) days with a negative BDG (<80 pg/mL). Post-prescription review occurred in 79% of prescribing episodes (median time to review 1 [0–3] day). Where suspected IFI was not confirmed, 38% episodes were stopped and 4% de-escalated within 5 days. Conclusions Achieving a better balance between promptly treating IFI patients and avoiding inappropriate antifungal prescribing in the ICU requires timely post-prescription review by specialist multidisciplinary teams and improved, evidence-based-risk prescribing strategies incorporating rapid diagnostics to guide AFT start and stop decisions.
