Scaling Safe Resident Driven OPAT bundle in a Lower Middle-Income Country: A Quality Improvement Intervention

Importance: OPAT is an underutilized strategy in low- and middle-income countries (LMICs). Addressing the knowledge gaps among frontline physicians through structured interventions is vital for optimizing hospital bed utilization and antimicrobial stewardship. Objective: To assess whether a structured multidisciplinary care bundle is associated with improved patient enrollment and clinical care quality in an OPAT program in India. Design, Setting, and Participants: This pre-post quality improvement study was conducted in the Department of General Medicine at a tertiary care referral hospital in Rishikesh, India. Data from patient encounters during a 6-month pre-intervention period (December 1, 2023 to May 31, 2024) were compared with encounters during a 6-month post-implementation period (January 1, 2025 to June 31, 2025). Participants included all postgraduate residents serving as frontline clinical practitioners. Interventions: A structured OPAT bundle comprising a formalized educational curriculum (interactive didactic sessions and bedside practical training), standardized eligibility screening, and a coordinated telephonic monitoring protocol (from June 1, 2024 to December 31, 2024). Main Outcomes and Measures: The primary outcome was the change in the number of eligible patients enrolled in OPAT. Secondary outcomes included clinical process quality indicators (counseling, IV access arrangement, and monitoring compliance), 30-day rehospitalization rates, and therapy-related complications. Results: A total of 20 preintervention patient encounters were compared with 39 postintervention encounters, with similar baseline characteristics between groups (mean age, 37 vs 40 years; male gender, 65% vs 69.2%). Prior to implementation, only 33.3% (20 of 60) of eligible patients received OPAT, whereas 100% (39 of 39) of eligible patients were enrolled following the intervention (p < 0.001). Key clinical processes reached 100% compliance post implementation, including patient counseling (40% vs 100%; p < 0.001), pre-discharge IV access (40% vs 100%; p < 0.001), and daily telephonic monitoring (10% vs 100%; p < 0.001). Safety outcomes remained stable, with no significant differences in readmission rates (5.0% vs 0%; p = 0.34) or drug-related complications. Conclusions and Relevance: This quality improvement study provides evidence that a structured package of OPAT bundle interventions is associated with a transition to universal enrollment of eligible patients and perfect adherence to safety indicators. These results suggest that standardizing the outpatient transition through physician education and coordinated monitoring is a feasible and effective strategy for optimizing hospital resource utilization in LMICs.
