Gender difference in delays to diagnosis and health care seeking behaviour in a rural area of Nepal.

SETTING: Directly observed treatment for tuberculosis using a short-course regimen (DOTS) was introduced in a rural area of Nepal. All new patients assigned to DOTS from mid-December 1997 to mid-June 1999 were eligible for the study. OBJECTIVE: To examine delays in tuberculosis (TB) diagnosis and compare health care seeking behaviour between men and women. DESIGN: A cross-sectional analysis of patient interviews. RESULTS: Women were found to have a significantly longer total delay before diagnosis of tuberculosis (median 2.3 months for men, 3.3 months for women). When they visited traditional healers first, women had a significantly longer delay than men from the first visit to health care providers to diagnosis (median 1.5 months for men, 3.0 months for women). More women (35%) visited traditional healers before diagnosis than men (18%), and were more likely to receive more complicated charms from traditional healers. Men tended to visit the government medical establishment first if they knew that free TB treatment was available, but women did not. CONCLUSION: Women were more likely to visit and to believe in traditional healers; this might lead to the longer delays experienced before TB diagnosis.

Tuberculosis treatment in nepal: a rapid assessment of government centers using different types of patient supervision.

SETTING: Urban and periurban government tuberculosis (TB) treatment clinics in Nepal. OBJECTIVE: To assess TB treatment supervision strategies and outcomes. DESIGN: Three types of treatment centers were selected according to intensity of treatment supervision: Group A-all patients supervised by directly observed therapy (DOT) at the treatment center during the intensive phase; Group B-flexible DOT where patient-nominated treatment supervisors include community or family members; Group C-drugs dispensed monthly and no supervised treatment. The cohort studied comprised all new patients starting treatment during a 5-month period in 1996 (n = 759). RESULTS: At group A treatment centers, 100% of patients had daily DOT supervised by treatment center staff during the intensive phase. At group B sites, 75% of nominated supervisors were family or community members and 13% of patients had no supervisor. At group C sites 93% of patients were unsupervised. Bacteriologically confirmed cure rates for smear-positive patients were 91% (95%CI 80.3-97.2) for A sites, 57% (95%CI 48.8-64.0) for B, and 34% (95%CI 25.1-40.4) for C. Treatment centers with the best results had good access to laboratory facilities, uninterrupted drug supply, longer clinic hours, standardized TB case management, and support from a non-governmental organization. CONCLUSION: At government facilities in Nepal, only group A treatment centers achieved World Health Organization global targets for cure. Group B treatment centers showed better outcomes than unsupervised therapy but did not achieve cure targets. Rapid low-cost assessments to collect data that are not routinely reported can improve the evaluation of program aspects such as supervision strategies.

Anti-tuberculosis treatment in private pharmacies, Kathmandu Valley, Nepal.

SETTING: Urban municipality of 150000 citizens in Kathmandu Valley, Nepal. OBJECTIVE: To determine 1) the perceptions among private pharmacists of characteristics of tuberculosis (TB) patients visiting private pharmacies in the area, 2) the sales of different anti-tuberculosis drugs, and 3) the interaction between private health providers and pharmacists. DESIGN: Between January and April 1998, semi-structured interviews were conducted with 98% (49/50) of the private drug-retailers in the area. RESULTS: Thirty-two (65%) pharmacies had sold anti-TB drugs during the last month. Forty-three (88%) said that most TB patients were of low socio-economic status and rarely bought drugs for more than a week at a time. Only eight (16%) reported that TB patients usually returned to buy the full course of drugs. Seventy-two per cent of total spending on anti-tuberculosis drugs was for different kinds of combinations of drugs. Nine per cent was spent on plain rifampicin, believed to be sold only to tuberculosis/leprosy patients. During the previous month, 5/13 (38%) of pharmacies with no doctors attached had sold anti-tuberculosis drugs compared with 27/38 (71%) of pharmacies with doctors attached to them (P < 0.05). CONCLUSION: The private sector offers an available and acceptable but non-affordable service for many TB patients. A substantial amount of anti-TB drugs are being sold in the private pharmacies. There is therefore a potential role for pharmacists to play in collaborative efforts between the private and public sector in TB control activities.

Sputum examination for acid-fast bacilli in private laboratories, Kathmandu Valley, Nepal.

OBJECTIVE: To investigate the characteristics of private laboratories and the process of sputum examination for acid-fast bacilli (AFB). DESIGN: A door-to-door survey of private laboratories in an urban municipality of Kathmandu valley was conducted during the first quarter of 1998. Semi-structured interviews were conducted with staff of 14/20 (70%) identified laboratories. RESULTS: All 14 private laboratories conducted sputum examination for AFB. The majority (71%) of staff lacked special training for AFB examinations. Monocular microscopes were commonly used (36%). Reagents were prepared irregularly, without quality control, and kept for as long as they lasted, often up to 4-6 months (43%). Laboratory registers were usually present (86%), but lacked information on patient's address and the purpose of the test. A median of 12.5 slides per laboratory had been examined during the previous month (range 0-70). A total of 235 AFB slides were examined, of which 18 (7.7%) were reported as positive. CONCLUSION: AFB examinations were widely available. Lack of training and quality control suggest a variable standard of AFB test results. It is recommended that the National Tuberculosis Programme (NTP) provide support and quality control to two to three (i.e., one for every 10) private laboratories in the area to secure private doctors' confidence in sputum testing.
