Infant and child mortality estimates in two counties of Liberia: 1984.

To estimate baseline infant and child mortality in Liberia, a survey was carried out in 1984 as part of the Combatting Childhood Communicable Diseases (CCCD) project. The project, a collaborative effort of the Liberian Ministry of Health, the US Agency for International Development, and the US Centers for Disease Control, is aimed at reducing childhood morbidity and mortality through oral rehydration therapy, vaccination and treatment for malaria. As a measure of programme impact, mortality estimates from this survey will be compared with those from a second survey after 4-5 years. A sample of 40 clusters (50-70 households per cluster) was used. The size is sufficient to detect a 25% reduction in mortality of children under 5 years of age. Mortality was estimated from a pregnancy history questionnaire asked of women aged 15-49 residing in cluster households. A reliability survey was conducted and pregnancies were matched to determine the level of omission of births and deaths. Results show a very high level of mortality with a risk of death in infancy above 20% and a risk of dying before the fifth birthday of one-third. Since the extent of omission of deaths in the first survey proved substantial, the reinterview survey was essential.

Immunization, oral rehydration therapy and malaria chemotherapy among children under 5 in Bomi and Grand Cape Mount counties, Liberia, 1984 and 1988.

As part of an evaluation of child survival programmes in 13 African countries, cluster surveys were carried out in two Liberian counties in 1984 and 1988 to measure use of three primary health care services: immunization of infants, antimalarial treatment of children with fever, and oral rehydration of childhood diarrhoea. Immunization rates increased (30-53% for DPT-1 and 13-33% for measles), treatment of malaria with drugs available in the home increased from 5 to 35%, and home use of sugar-salt solution to prevent dehydration remained essentially unchanged, 5.9% in 1984 and 3.8% in 1988.

Infant and child mortality in two counties of Liberia: results of a survey in 1988 and trends since 1984.

A baseline survey of childhood mortality in two counties of Liberia in 1984 found the risk of dying before age 5 to be almost one-third. Three years into the Combatting Childhood Communicable Diseases (CCCD) project, a survey using a pregnancy history questionnaire was conducted in the same clusters to determine if any change in mortality had occurred. Reinterviews were done in a subsample and pregnancies were matched from the two surveys to determine levels of missing events. After adjustment for omission, infant mortality was estimated at 180 per 1000, a 25% decline from the estimated 1984 level. Childhood mortality declined by an estimated 28%. Tabulations of death by reported cause using a verbal autopsy questionnaire showed that the risks of neonatal tetanus and fever associated deaths declined significantly. These reductions might have been a direct result of programme activities which were shown by a marked increase in tetanus toxoid immunization and access to antimalarial drugs in the study area.

Analyzing organizational practices in local health departments.

Few researchers have examined the problem of comparing the performances of local health departments. A contributing factor is the lack of a uniform method for describing the range of public health activities. The Centers for Disease Control and Prevention's Public Health Practice Program Office has identified 10 organizational practices that may be used to assure that the core functions of public health are being carried out at a local health department. The researchers determined the percentage of time devoted to each of the 10 practices by individual employees at a local public health unit in Tampa, FL. They identified the manpower expenditures and hours allocated to each of the 10 practices within the major program divisions of the unit. They found that the largest portion of manpower resources was allocated to implementing programs. A much smaller fraction of agency resources was devoted to analysis of the health needs of the community and to the development of plans and policies. Together, primary care and communicable disease programs accounted for fully three-quarters of the resources, environmental health for 11 percent, and administrative support services for 13 percent. With continuing refinement and modification, the methodology could provide a highly effective basis for describing and analyzing the activities and performances of local health departments.
