The effectiveness of a dose based reporting tool in reducing vaccine wastage at primary care clinics in Delhi, India: an operational research study.

ABSTRACT: Minimizing vaccine wastage and associated costs is considered a key target for appropriate vaccine management. In India, the Rotavirus Vaccine (RVV) (2019) and the fractionated injectable polio vaccine (f-IPV) (2016) are more prone to wastage with high procurement costs.In this operational research study, we determined the effectiveness of a (self-designed) dose based reporting tool (DBRT) in reducing vaccine (f-IPV and RVV) wastage at primary care facilities in India during December 2019 to March' 2020.Data reports of all the immunization sessions conducted at three primary care facilities were analyzed to calculate the wastage rates of the RVV and the f-IPV for the following periods: (1). Period of initiation (August-November' 2019) (2). Pre-intervention with sensitization of healthcare providers (December' 2019-January' 2020) (3). Post-intervention after application of the DBRT.Intervention: The DBRT is a paper-based reporting format that assigns a unique code to each RVV and IPV vial. The health facility is required to report the total doses administered from each coded vial during every immunization session by updating it on the assigned reporting format.Pre-intervention, the average monthly wastage of f-IPV was 23.5% and of the RVV ranged from 18%-31%. Post-intervention, on using the DBRT, the monthly wastage of both RVV and f-IPV dropped significantly to 8.6% and 11.4%, respectively. During the subsequent month, the IPV wastage further decreased to only 4.7%.In conclusion, the DBRT reduces vaccine wastage in government primary care facilities by enabling a paper audit trail that promotes responsiveness and accountability among healthcare workers directly involved in vaccine administration.

Project description:Curtailment of turbine operations during low wind conditions has become an operational minimization tactic to reduce bat mortality at terrestrial wind energy facilities. Site-specific studies have demonstrated that bat activity is higher during lower wind speeds and that operational curtailment can effectively reduce fatalities. However, the exact nature of the relationship between curtailment cut-in speed and bat fatality reduction remains unclear. To evaluate the efficacy of differing curtailment regimes in reducing bat fatalities, we examined data from turbine curtailment experiments in the United States and Canada in a meta-analysis framework. We used multiple statistical models to explore possible linear and non-linear relationships between turbine cut-in speed and bat fatality. Because the overall sample size for this meta-analysis was small (n = 36 control-treatment studies from 17 wind farms), we conducted a power analysis to assess the number of control-treatment curtailment studies needed to understand the relationship between fatality reduction and change in cut-in speed. We also identified the characteristics of individual curtailment field studies that may influence their power to detect fatality reductions, and in turn, contribute to future meta-analyses. We found strong evidence that implementing turbine curtailment reduces fatality rates of bats at wind farms; the estimated fatality ratio across all studies was 0.37 (p < 0.001), or a 63% decrease in fatalities. However, the nature of the relationship between the magnitude of treatment and reduction in fatalities was more difficult to assess. Models that represented the response ratio as a continuous variable (e.g., with a linear relationship between the change in cut-in speed and fatalities) and a categorical variable (to allow for possible non-linearity in this relationship) both had substantial support when compared using AICc. The linear model represented the best fit, likely due to model simplicity, but the non-linear model was the most likely without accounting for parsimony and suggested fatality rates decreased when the difference in curtailment cut-in speeds was 2m/s or larger. The power analyses showed that the power to detect effects in the meta-analysis was low if fatality reductions were less than 50%, which suggests that smaller increases in cut-in speed (i.e., between different treatment categories) may not be easily detectable with the current dataset. While curtailment is an effective operational mitigation measure overall, additional well-designed curtailment studies are needed to determine precisely whether higher cut-in speeds can further reduce bat fatalities.

Project description:BackgroundThe mass scale-up of antiretroviral therapy (ART) in Zambia has taken place in the context of limited infrastructure and human resources resulting in many operational side-effects. In this study, we aimed to empirically measure current workload of ART clinic staff and patient wait times and service utilization.MethodsWe conducted time and motion (TAM) studies from both the healthcare worker (HCW) and patient perspectives at 10 ART clinics throughout Zambia. Trained personnel recorded times for consecutive discrete activities based on direct observation of clinical and non-clinical activities performed by counselors, clinical officers, nurses, and pharmacy technicians. For patient TAM, we recruited consenting patients and recorded times of arrival and departure and major ART services utilized. Data from 10 clinics were pooled to evaluate median time per patient spent for each activity and patient duration of stay in the clinic.ResultsThe percentage of observed clinical time for direct patient interaction (median time per patient encounter) was 43.1% for ART counselors (4?min, interquartile range [IQR] 2-7), 46.1% for nurses (3?min, IQR 2-4), 57.2% for pharmacy technicians (2?min, IQR 1-2), and 78.5% for clinical officers (3?min, IQR 2-5). Patient workloads for HCWs were heaviest between 8?AM and 12?PM with few clinical activities observed after 2?PM. The length of patient visits was inversely associated with arrival time - patients arriving prior to 8?AM spent 61% longer at the clinic than those arriving after 8?AM (277 vs. 171?min). Overall, patients spent 219?min on average for non-clinical visits, and 244?min for clinical visits, but this difference was not significant in rural clinics. In comparison, total time patients spent directly with clinic staff were 9 and 12?min on average for non-clinical and clinical visits.ConclusionCurrent Zambian ART clinic operations include substantial inefficiencies for both patients and HCWs, with workloads heavily concentrated in the first few hours of clinic opening, limiting HCW and patient interaction time. Use of a differentiated care model may help to redistribute workloads during operational hours and prevent backlogs of patients waiting for hours before clinic opening, which may substantially improve ART delivery in the Zambian context.
