Engagement of the private sector and community leaders are popular strategies for improving tuberculosis (TB) case detection. However the impact of engaging pharmacies and community shop keepers in TB referral varies and the best method to achieve it are unknown.
To evaluate changes in referral and TB case detection following workshops and/or motivational “detailing” visits, mystery clients visited 188 pharmacies and 103 grocery stores to seek advice for chronic symptoms reflecting pulmonary TB. Most sites (89% n=255) were exposed to “detailing” and 26.8% (76) also attended 1 hour workshops designed by the National TB program and KNCV Tuberculosis Foundation (KNCV). Sites were scored pre- and post-intervention, obtaining 1 point each for a) spontaneous recognition of TB symptoms, b) acknowledgement of symptoms as possibly TB when prompted, c) referral to medical care d) not promoting drugs e) exhibiting TB health education materials on site and f) referral of mystery clients to the TB program.
The TB recognition and referral scores of all exposed establishments increased by an average of 2.0 points (95%C.I. 1.9- 2.1) at post-test compared with an increase of 0.6 points (95%C.I. 0.4-.0.9) among those in the comparison group (p<0.001). Attempted sales of antibiotics and palliatives declined from 38.3% at baseline to 16.1%. After six months, 33.1% of pharmacies and 22.7% of grocery stores reported referring. Seven smear-positive TB cases were diagnosed from among 70 TB suspects referred by pharmacies, but none from among 30 suspects sent by groceries. TB investigations rose by 8.4% in the area for a six month period. The intervention is likely to have contributed to the doubling of TB case notifications over two years.
A simple motivation intervention led to improvement in referral and TB case detection. The National TB program introduced interventions with pharmacies to other provinces.
