Using a quality improvement tool, Plan-Do-Study-Act cycle, to boost TB notification in India post-Covid-19 pandemic.

Quality improvement tools such as the Plan-Do-Study-Act (PDSA) cycle hold tremendous potential to improve the quality of healthcare in India. The electronic-PDSA tool was previously developed by CETI (Collaboration to Eliminate TB among Indians) and successfully piloted in small groups. In this study the e-PDSA was scaled up across the nation over a brief 10 week period to boost TB notification by training District Tuberculosis Officers (DTOs) virtually post-Covid-19 pandemic. Quality improvement counselors, who were interns from Masters in Public Health Institutions, were liaisons to "hand-hold" and assist the DTOs through the PDSA cycle. The course was voluntary and offered to all DTOs through Central TB Division and State TB Officers from May 2022 to July 2022. Of the 779 Districts in India and nearly equal number of DTOs, 546 (70%) DTOs enrolled in the course and of these 437 (80%) conducted a PDSA while 342 (43%) districts/DTOs did not enroll or did not complete a PDSA. With a baseline notification in February-March-April 2022 and intervention in May-June-July 2022; 55% of the districts in the PDSA group showed improvement in TB Notification compared to 45% in the non-PDSA group. When data was analyzed by population (not district) there was a trend in increase in notification post-pandemic in both PDSA and non-PDSA groups, and the PDSA group had a slightly higher 5.6 per 100,000 population improvement compared to 5.0 per 100,000 in the non-PDSA group. The cost of intervention was $40,000 or $92 per DTO for three months. The course was highly acceptable with DTOs rating 4.3 out of 5 in recommending the course to other DTOs. Our data shows that a large scale-up of the PDSA cycle is feasible, economical and effective with little additional resources. The focus was on increasing the efficiency of the existing processes well within the authority of the DTO. Repeat cycle of PDSA with notification and other measures such as presumptive sputum examination could significantly impact the program and help to achieve TB Free India.
