In Indonesia responsibility for immunizations is placed on local government health centres and on the nurses who provide the immunizations at each centre. An on-the-job peer training programme for these nurses, which was designed to improve the immunization performance of poorly performing health centres in terms of coverage and practice in Maluku province, was evaluated. Experienced immunization nurses were sent to health centres where nurses were inexperienced or performing poorly; the experienced nurses spent 1-2 weeks providing on-the-job training for the less experienced ones. An evaluation of the 13 centres that participated in the programme and the 95 that did not found that the programme increased both immunization coverage and the quality of practice. Coverage of diphtheria/pertussis/tetanus (DPT), polio, and measles vaccinations rose by about 39% in all 13 participating centres when compared with non-participating centres, and by about 54% in the 11 centres that had a functioning transportation system during the year after training. These results reflect increases in the actual number of doses given and improvements in the accuracy of reports. Potential threats to the study's validity were examined and found not to be significant. The out-of-pocket cost of the training programme was about US$ 53 per trainee or about US$ 0.05 per additional vaccine reported to have been given. The marginal cost per additional fully immunized child was estimated to be US$ 0.50.
Jails are an important reservoir of tuberculosis infection in the United States. Screening for active disease in these high-risk settings is difficult. We used decision analysis to assess the cost effectiveness of routine miniature chest radiography for screening for tuberculosis on admission to jail. Infection rates, probabilities, and costs associated with detecting and treating tuberculosis were derived from published studies. We calculated an average total cost of $6.60 per inmate for routine radiograph screening on admission to jail. The cost of screening for active tuberculosis with miniature chest radiography was estimated to be $9,600 per case identified, compared with $32,100 per case with tuberculin skin testing and $54,100 per case with symptom screening. Chest radiography would also identify substantially more cases than other methods of screening. Screening for tuberculosis with miniature chest radiography is cost effective even under a wide range of assumptions regarding risk factors and prevalence of disease. Miniature chest radiography should be strongly considered as an important tool in the fight to eliminate tuberculosis from the high-risk populations that may be reached through screening in jails.
