Impacts of training of village health volunteers in reduction of morbidity from acute respiratory infections in childhood in southern Thailand.
In 1990, the Ministry of Public Health of Thailand started a five-year education program on management of cases with acute respiratory infection (ARI). The objective of this-study was to test whether such a program could reduce the average number of sick days of the target children. 30 villages in the study district were randomly allocated into 15 study and 15 control villages. A 2-day training workshop for village health volunteers from the study villages was conducted. The cohort of children age below 5 years in the two areas were followed-up for 19 week in the peak season of the disease. Among the 664 and 649 target children with 67,083 and 67,984 child-days observed in the study and the control villages, 71 and 41 children, respectively, were free from any episode. The preventive odds ratio of treatment adjusted for age and village effects = 0.88, 95% (CI 0.4-1.95). The median of the average sick periods in the individuals were 27 and 34 days, respectively. After adjusting for age, episodes/month and locality, the ratio of average sick days between children in the study and control villages was 0.89 (95% CI 0.76-1.05) or 11% shorter duration without statistical significance. The adjusted odds ratios of visiting the health center, private clinics, the community hospital and provincial hospital were 0.95 (95% CI 0.69-1.25), 1.43 (95% CI 0.98-2.11), 2.01 (95% CI 1.06-3.82) and 4.71 (95% CI 1.50-14.8), respectively. The training program thus had rather little impact on morbidity of the disease but tended to promote utilization of higher level of health services by the affected children.
