Study of the structure and functioning of referral mechanism of patients receiving treatment and records linkage under Revised National Tuberculosis Control Programme (RNTCP) of Government of India

Abstract

BackgroundThe reliable and successful performance of the Revised National Tuberculosis Control Programme (RNTCP) “referral mechanism” is profoundly important in the medical college scenario, and it is an important requirement of the programme to have feedback status report of the referred patients. MethodsAn observational study on tuberculosis (TB) patients referred from Directly Observed Treatment (DOT) Centre, Sri Venkateswara Institute of Medical Sciences (SVIMS) was conducted during the years 2010 to 2012 (n=622). Subjects referred to other TUs within the District but failed to report there within 45 days constituted “cases” and subjects, who obtained treatment from the TUs they were referred to “controls”. The initial information or confirmation of registration for treatment status feedback were obtained from patient/Senior Treatment Supervisor (STS)/District Tuberculosis Centre (DTC) levels respectively both before using intervention (Phase I, year 2010) and after using intervention (Phase II, years 2011 and 2012) by sending day-to-day text messaging of referral details of patients to the STS and District Tuberculosis Officer (DTO). ResultsDuring Phase I, the distribution of subjects (n=242) in the ages ≤25, 26–50, and ≥51 years was similar in both the cases and control subjects (p=0.054). Further, there was no statistically significant difference in the median age of the cases and controls [34.5 (interquartile range, IQR 31–51) vs 39 (30–54); p=0.319]. There was no statistically significant difference in other parameters, such as gender distribution (p=0.9748); availability of phone numbers (p=0.9614); type of disease (p=0.8395); and type of case (p=0.0793). In Phase II, the effect of intervention on feedback related parameters showed statistically significant improvement in all the parameters such as initial feedback levels obtained within 15 days (p=0.0077); within 45 days (p<0.0001); above 45 days (p<0.0001); registration status confirmation within 45 days (p=0.0343); mismatch of feedback received by observer (p<0.0001); and telephone number of patients recorded (p<0.0001). ConclusionOur findings suggest that text messaging reminders may be an important tool to achieve optimal feedback response in resource-limited settings.
