What happened to the IUD in Ghana?

The intrauterine contraceptive device (IUD) is a safe and reversible contraceptive method that requires little effort on the part of the user. Once inserted, it offers 10 years of protection against pregnancy. However, its use in Ghana has stagnated in relation to other contraceptive methods. An exploratory study was, therefore, conducted to examine the client, provider and system characteristics that affect the demand for IUD. Data were gathered through secondary analysis, in-depth interviews, focus group discussions and simulated client survey. The stagnating demand for IUD is attributed to clients' perceptions and rumours about IUD. The fear of excessive bleeding and weight loss discourages potential users. The product design was also perceived to be unacceptable. Demand creation for the IUD has been poor and the number of providers with practical experience of insertion is insufficient. Contrary to the belief that providers' bias contributes to the decline in use, findings show that providers have a favourable attitude towards the product.

Improving adherence to malaria treatment for children: the use of pre-packed chloroquine tablets vs. chloroquine syrup.

Malaria is a major cause of morbidity and mortality among children under five in sub-Saharan Africa. Prompt diagnosis and adequate treatment of acute clinical episodes are essential to reduce morbidity and prevent complications and mortality. In many countries, chloroquine syrup is the mainstay of malaria treatment for children under five. Not only is syrup more expensive than tablets, adherence to the prescribed dose at home is a problem because mothers use wrongly sized measuring devices or have difficulty with the instructions. We investigated the impact of introducing pre-packed tablets for children on adherence to treatment and compared the total cost of the tablets with that of syrup. Children aged 0--5 years diagnosed with malaria at the clinic over a 6-week period received either pre-packed tablets or syrup by random assignment. The principal caregivers were interviewed at home on day 4 after attending the clinic. Of the 155 caregivers given pre-packed tablets, 91% (n=141) adhered to the recommended dosage, while only 42% (n=61) of 144 who were provided syrup did. Only 20% of caregivers who received syrup used an accurate 5 ml measure. The cost of treatment with tablets was about one-quarter that of syrup and 62% (n=96) of caregivers preferred tablets. Pre-packed chloroquine tablets are a viable alternative to syrup.

Impact of prepackaging antimalarial drugs on cost to patients and compliance with treatment.

OBJECTIVE: To examine the extent to which district health teams could reduce the burden of malaria, a continuing major cause of mortality and morbidity, in a situation where severe resource constraints existed and integrated care was provided. METHODS: Antimalarial drugs were prepackaged into unit doses in an attempt to improve compliance with full courses of chemotherapy. FINDINGS: Compliance improved by approximately 20% in both adults and children. There were 50% reductions in cost to patients, waiting time at dispensaries and drug wastage at facilities. The intervention, which tended to improve both case and drug management at facilities, was well accepted by health staff and did not involve them in additional working time. CONCLUSION: The prepackaging of antimalarials at the district level offers the prospect of improved compliance and a reduction in the spread of resistance.

The use of grid sampling methodology for rapid assessment of the distribution of bancroftian filariasis.

The recent World Health Assembly Resolution to eliminate lymphatic filariasis as a public health problem once more brings to the fore the need for reliable data for the effective planning of disease control programmes. Most countries do not have data on the distribution of lymphatic filariasis and are therefore not in the position to initiate control programmes based on sound baseline data. We tested in Ghana in 1998-99 a method for the Rapid Assessment of the Geographical Distribution of Bancroftian Filariasis (RAGFIL) that uses a spatial sampling grid with 50 km between sampled villages, rapid assessment surveys for filariasis prevalence in the sampled villages and spatial analysis to estimate the geographical distribution of filariasis throughout the study area. The prevalence contours obtained with the 50 x 50-km sampling grid were operationally similar to those obtained with a 25 x 25-km grid. The predicted prevalence was not statistically different from the sample survey prevalence in 57 independent villages and the 50 x 50-km grid appears adequate for rapid mapping of filariasis. For the purpose of filariasis mapping, the antigen test would seem a better diagnostic test than clinical examination for hydrocoele. We recommend that a regional approach to mapping be used because of the importance of cross-border foci as demonstrated by our findings from the north of Ghana. Application of the method will provide the minimal information required for effective planning of treatment programmes, and will facilitate estimation of the number of people to be treated. It will also help improve estimates of the number of people at risk and affected, and of the burden of disease due to lymphatic filariasis in Africa.

The potential role of peripheral health workers and community key informants in the rapid assessment of community burden of disease: the example of lymphatic filariasis.

Data for planning disease control programs in most developing countries is often not available because they are usually expensive to gather. This study explored the potential use of peripheral health staff and community key informants in gathering community-level data about lymphatic filariasis. Agreement between findings of health workers and those of physicians was very high (kappa 0.66-0.87) for the clinical conditions examined. The prevalence of hydrocele was found to be a good predictor of communities at risk of filariasis. Community key informants provided very useful qualitative and quantitative data on the prevalence of clinical filariasis. The need to use nontraditional health professionals in gathering data for planing control programs is discussed.

The economic burden of lymphatic filariasis in northern Ghana.

The socio-economic impact of lymphatic filariasis was investigated in a rural community in northern Ghana, as part of a multi-country study. The entire community was followed up for a period of one full calendar year, to document episodes of acute adenolymphangitis (ADL), treatment seeking and the cost of treatment. Cases of chronic filarial disease identified at the start of the study were also visited every 3 months to monitor treatment seeking and the costs of treatment. The subjects, who were mainly subsistence farmers, were found to be materially very poor. The incidence of ADL, which lasted an average of 5 days, was found to be very high. Most of those affected were unable to perform their normal activities for much of the ADL episode. In general, most subjects with long-standing chronic disease, such as elephantiasis of the leg and hydroceles, tended not to seek treatment except when there was superimposed ADL. Some aspects of treatment seeking, the cost of treatment, the burden of the disease on the community, and the public-health implications are discussed.
