OBJECTIVE: To examine the effects on immunization equity of the large-scale contracting of primary health-care services in rural areas of Cambodia.
METHODS: Data were obtained pre-intervention and post-intervention from a large-scale quasi-experiment in contracting with nongovernmental organizations to provide primary health care in nine rural districts of Cambodia between 1999 and mid-2001. Coverage targets and equity targets for all primary health-care services, including immunization of children, were explicitly included in the contracts awarded in five of nine rural districts which together have a population of over 1.25 million people. The remaining four districts used the traditional government model for providing services and were given identical targets.
FINDINGS: After the 2.5 years of the trial, bivariate and multivariate analyses of the results suggested that although there was a substantial increase in the proportion of children who were fully immunized in all districts, children in the poorest 50% of households in the districts served by contractors were more likely to be fully immunized than poor children living in similar circumstances in districts using the government's model, all other things being equal.
CONCLUSION: The contracting approach described in this paper suggests a means of moving towards a more equitable distribution of immunization services in developing countries.
OBJECTIVE: To evaluate the safety and coverage benefits of auto-disable (AD) syringes, weighed against the financial and logis- tical costs, and to create appropriate health policies in Madagascar.
METHODS: Fifteen clinics in Madagascar, trained to use AD syringes, were randomized to implement an AD syringe only, mixed (AD syringes used only on non-routine immunization days), or sterilizable syringe only (control) programme. During a five-week period, data on administered vaccinations were collected, interviews were conducted, and observations were recorded.
FINDINGS: The use of AD syringes improved coverage rates by significantly increasing the percentage of vaccines administered on non-routine immunization days (AD-only 4.3%, mixed 5.7%, control 1.1% (P<0.05)). AD-only clinics eliminated sterilization sessions for vaccinations, whereas mixed clinics reduced the number of sterilization sessions by 64%. AD syringes were five times more expensive than sterilizable syringes, which increased AD-only and mixed clinics' projected annual injection costs by 365% and 22%, respectively. However, introducing AD syringes for all vaccinations would only increase the national immunization budget by 2%.
CONCLUSION: The use of AD syringes improved vaccination coverage rates by providing ready-to-use sterile syringes on non-routine immunization days and decreasing the number of sterilization sessions, thereby improving injection safety. The mixed programme was the most beneficial approach to phasing in AD syringes and diminishing logistical complications, and it had minimal costs. AD syringes, although more expensive, can feasibly be introduced into a developing country's immunization programme to improve vaccination safety and coverage.
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.
The medical division of the International Committee of the Red Cross undertook an expanded programme of immunization in rural areas of Mozambique controlled by the resistance. This programme was evaluated by a 30 cluster survey which showed that 82 per cent of children between 1 and 5 years and 81.7 per cent of mothers of children of less than 1 year had had contact with the vaccination service. Full vaccination was achieved in 40.6 and 35.2 per cent respectively. The reasons for immunization failure were established. The study shows that vaccination of the civilian population of a developing country at war is possible and, importantly, the outcome of the programme can be assessed.
This paper describes the effectiveness for child health of a primary health care approach developed in Bolivia by Andean Rural Health Care and its colleagues, the census-based, impact-oriented (CBIO) approach. Here, we describe selected achievements, including child survival service coverage, mortality impact, and the level of resources required to attain these results. As a result of first identifying the entire programme population through visits at least biannually to all homes and then targeting selected high-impact services to those at highest risk of death, the mortality levels of children under five years of age in the established programme areas was one-third to one-half of mortality levels in comparison areas. Card-documented coverage for the complete series of all the standard six childhood immunizations among children 12-23 months of age was 78%, and card-documented coverage for three nutritional monitorings during the previous 12 months among the same group of children was 80%. Coverage rates in comparison areas for similar services was less than 21%. The local annual recurring cost of this approach was US $8.57 for each person (of all ages) in the programme population. This cost includes the provision of primary care services for all age groups as well as targeted child survival services. This cost is well within the affordable range for many, if not most, developing countries. Manpower costs for field staff in Bolivia are relatively high, so in countries with lower salary scales, the overall recurring cost could be substantially less. An Expert Review Panel reviewed the CBIO approach and found it to be worthy of replication, particularly if stronger community involvement and greater reliance on volunteer or minimally paid staff could be attained. The results of this approach are sufficiently promising to merit implementation and evaluation in other sites, including sites beyond Bolivia.
Village health rooms (VHRs) were established in villages with no on-site health facilities in the Hebron District of the West Bank, beginning in 1985. By 1991, the program served a total population of 40,000 in 49 VHRs and by the end of 1996 covered 69 villages in Hebron and 20 in other districts that were previously served by visiting vaccination teams and nearby clinics. The VHRs provide close contact with the population of mothers for well child and pregnancy care, health education and provide visiting doctor/nurse teams for backup services and supervision. Data on coverage, utilization, costs, and outcome measures are presented. The program is accepted and grows despite adverse social and political conditions.
A strategy of home visits to maximize children's immunization coverage was implemented in three towns in Ghana. The strategy was tested in town 1 in a controlled trial where clusters of children were allocated to the intervention and control groups. A total of 200 mothers in the intervention group were visited at home by non-health workers and their children were referred to a routine under-fives' clinic. Subsequent home visits targeted at those who failed to complete immunization schedules were made by nurses. After 6 months, coverage had risen from 60% to 85%, which was 20% higher than in the town 1 control group of 219 age-matched children (P < 0.005). A similar home-visiting strategy in a neighbouring town resulted in a rise in coverage from 38% to 91% (n = 55), mainly through home immunizations. Children were more likely to complete the schedule if their fathers were interviewed and participated in the decision to send them to the clinic. Countries with national service programmes can use a home-visiting strategy to supplement and strengthen their routine immunization programmes. A wide range of other community-based primary health care interventions could also be tested and implemented using this methodology. The strategy of home visits to maximize children's immunization coverage was evaluated in three towns in Eastern Ghana in 1991-92. Mothers were visited by a non-health worker and referred to an under-fives clinic; if they failed to follow through, a second home visit was made by a nurse. After 6 months, the proportion of completed schedules was significantly higher among the 200 intervention group children than the 219 controls, whether measured by card only (85.5% vs. 62.6%) or by card and history (86.0% vs. 66.7%). Complete coverage was most likely when the mother followed the advice of the interviewer and, without further prompting, brought the child to the health clinic (relative risk (RR), 1.43; 95% confidence interval (CI), 1.17-1.75), when a nurse met the mother at a subsequent home visit (RR, 0.40; 95% CI, 1.00-1.96), and if fathers were interviewed and participated in the decision to send the child to the clinic (RR, 1.85; 95% CI, 1.10-3.12). During the home visit period, 70.2% of previously uncompleted immunization schedules were completed. Other potential advantages of home visits include disaggregated data collection, identification of pockets of low immunization coverage, information on health service users' perspectives, and the involvement of fathers in health care decision making. However, home visiting should be viewed as a means of strengthening routine primary health care service provision and not as a substitute for clinic services.
A growing number of non-governmental organizations (NGOs) are adopting the collateral-free credit programs by anchoring them with their social development programs aimed at improved program effectiveness and sustainability. Drawing upon a sample of 3,564 targeted poor households covered by five small NGOs in rural Bangladesh, this study finds that the NGO credit-members as well as those who reside in the NGO program area are higher adopters of child immunization than those in the non-program area. Similarly, the study found that infant and child mortality is lower among the NGO credit members than among the non-members and that under five-year deaths of children progressively decline with the increase in the doses of vaccines. Implications of these findings are discussed in the study.
OBJECTIVE: To evaluate the results of a vaccination strategy on children under one year of age, aimed at increasing the coverage of the complete vaccination scheme, and at improving early entry into the program. MATERIAL AND METHODS: In Tixtla, Guerrero, Mexico, from April to December 1994, two basic geo-statistical areas (BGSA) were studied. Each area had an average number of 100 children under one year of age. In the area of intervention, people from the community were hired on a permanent basis for early recruitment of children (under two months of age) and for appropriate vaccination of children with incomplete vaccination schemes. In the control area vaccination campaigns were offered periodically. RESULTS: It was found that the strategy of intervention increased the percentage of completed vaccination schemes, from 21.1% to 93.5% among children under one year of age, as well as the recruitment rate. CONCLUSIONS: This strategy can help to achieve a better coverage of vaccination programs in urban areas where coverage is low.
From March to September 1990 the Philippine Department of Health, with the assistance of the HEALTHCOM Project, carried out a national mass-media communication campaign to support routine vaccination services. The essential elements of the campaign strategy were as follows: focusing on measles as a way to get mothers to bring their children to the health centre; emphasizing logistic knowledge in the mass-media messages, in particular popularizing a single day of the week as "vaccination day" and giving clear information about the age for measles vaccination; and focusing on urban areas, which had lower vaccination rates than rural areas. Evaluation of the effects of the campaign indicates an increase in vaccination coverage and a substantial increase in the timeliness of vaccination that can be attributed to improvement in carers' knowledge about vaccination. Furthermore, most of the observed increase in knowledge was related to exposure to the mass-media campaign. There was no evidence of any programmatic change that could account for the increase in vaccination or evidence that increased health education efforts at health centres could account for the change in knowledge. These results indicate that when countries meet certain conditions--a high level of access to the media, sufficient expertise and funds available to develop and produce high-quality radio and television advertisements, and a routine system that is able to serve the increased demand--a mass communication campaign can significantly improve vaccination coverage. The Philippine Department of Health conducted a national mass media communication campaign during the period March-September 1990 to support routine vaccination services. The campaign focused upon measles as a way to get mothers to bring their children to the health center, emphasized logistic knowledge in the mass-media messages, and focused upon urban areas with lower vaccination rates than rural areas. Examples of logistic emphasis include designating one day per week as vaccination day and giving clear information about the age for measles vaccination. An increase in vaccination coverage and a substantial increase in the timeliness of vaccination were observed which may be attributed to the improvement in carers' knowledge about vaccination. Most observed increase in knowledge was related to campaign exposure. There was no evidence of any programmatic change which could account for the increase in vaccination or evidence that increased health education efforts at health centers could account for the change in knowledge. These results indicate that when countries meet certain conditions, a mass communication campaign can significantly improve vaccination coverage. Conditions include access to media, expertise, and funds to produce and air high quality television and radio spots, and a routine system capable of handling the increased demand.
