Spatial Analysis of Land Cover Determinants of Malaria Incidence in the Ashanti Region, Ghana

Malaria belongs to the infectious diseases with the highest morbidity and mortality worldwide. As a vector-borne disease malaria distribution is strongly influenced by environmental factors. The aim of this study was to investigate the association between malaria risk and different land cover classes by using high-resolution multispectral Ikonos images and Poisson regression analyses. The association of malaria incidence with land cover around 12 villages in the Ashanti Region, Ghana, was assessed in 1,988 children <15 years of age. The median malaria incidence was 85.7 per 1,000 inhabitants and year (range 28.4–272.7). Swampy areas and banana/plantain production in the proximity of villages were strong predictors of a high malaria incidence. An increase of 10% of swampy area coverage in the 2 km radius around a village led to a 43% higher incidence (relative risk [RR] = 1.43, p<0.001). Each 10% increase of area with banana/plantain production around a village tripled the risk for malaria (RR = 3.25, p<0.001). An increase in forested area of 10% was associated with a 47% decrease of malaria incidence (RR = 0.53, p = 0.029)

Improving access to health care for malaria in Africa: a review of literature on what attracts patients

BACKGROUND: Increasing access to health care services is considered central to improving the health of populations. Existing reviews to understand factors affecting access to health care have focused on attributes of patients and their communities that act as 'barriers' to access, such as education level, financial and cultural factors. This review addresses the need to learn about provider characteristics that encourage patients to attend their health services. METHODS: This literature review aims to describe research that has identified characteristics that clients are looking for in the providers they approach for their health care needs, specifically for malaria in Africa. Keywords of 'malaria' and 'treatment seek*' or 'health seek*' and 'Africa' were searched for in the following databases: Web of Science, IBSS and Medline. Reviews of each paper were undertaken by two members of the team. Factors attracting patients according to each paper were listed and the strength of evidence was assessed by evaluating the methods used and the richness of descriptions of findings. RESULTS: A total of 97 papers fulfilled the inclusion criteria and were included in the review. The review of these papers identified several characteristics that were reported to attract patients to providers of all types, including lower cost of services, close proximity to patients, positive manner of providers, medicines that patients believe will cure them, and timeliness of services. Additional categories of factors were noted to attract patients to either higher or lower-level providers. The strength of evidence reviewed varied, with limitations observed in the use of methods utilizing pre-defined questions and the uncritical use of concepts such as 'quality', 'costs' and 'access'. Although most papers (90%) were published since the year 2000, most categories of attributes had been described in earlier papers. CONCLUSION: This paper argues that improving access to services requires attention to factors that will attract patients, and recommends that public services are improved in the specific aspects identified in this review. It also argues that research into access should expand its lens to consider provider characteristics more broadly, especially using methods that enable open responses. Access must be reconceptualized beyond the notion of barriers to consider attributes of attraction if patients are to receive quality care quickly

Assessing Health Workers Knowledge on the Determinants of Health: A Study in Enugu Nigeria

Background: Different social economic and personal factors have been touted as determining a person's health. This encompasses a person's living environment, economic status, genetic makeup, physical attributes and not just access to health services. It is important that health workers recognize that a person's socio-economic environment can have an adverse effect on the health status of the individual so as to capture this aspect in their choice of intervention. Methods: The study was carried out in two tertiary institutions in Enugu state selected purposively because they housed a dental clinic. It was a descriptive cross sectional study consisting of 87 participants which represented all the dental staff available during the study period. The participants were interviewed with a structured questionnaire used to elicit the knowledge of health workers on health determinants. Results: When individual factors were considered, a greater percentage of health workers, believed that safe drinking water (98.9%), where a person lives (96.6%) and a balanced diet, affect health more than availability of health services (59.8%) or the ability of the health care system to meet the needs of the people (55.2%). However when ranking the magnitude of the contribution of the various determinants of health the majority (37.9%) considered a good health care system the most important contributory factor to determining health of a community while social environment (14.9%) was the least. Conclusion: The ranking of good healthcare system over social environment points to the emphasis being laid on curative instead of preventive management of diseases, which have been entrenched in our health workers. Considerations should therefore be made for public health institutions to dwell more on health promotion and education activities to educate both health personnel and individuals on the importance of the social determinants on health.

Determinants of non-adherence to subsidized anti-retroviral treatment in southeast Nigeria.

The anti-retroviral (ARV) treatment programme in Nigeria is delivered through selected teaching and mission hospitals at a free/subsidized rate. The government aims to scale up ARV treatment in the country. However, non-adherence to ARV medication can lead to viral resistance, treatment failure, toxicities and waste of financial resources. This study examined the factors responsible for non-adherence to free/subsidized ARV treatment in south-east Nigeria. The study was cross-sectional and descriptive. Information was collected from 174 patients selected by simple random sampling from the register of all patients who had been on anti-retroviral therapy (ART) for at least 12 months at the beginning of the study period. Patients were identified during their clinic visits. Information on their socio-demographic profile, ARV treatment and determinants of non-adherence to ARV treatment was obtained from those who gave consent, using pre-tested interviewer-administered questionnaires. All patients clearly understood the need to take ARV drugs throughout their lives, and what the costs entailed. They understood the need for periodic testing, the probability that complications would develop, cost of transportation to treatment site and the daily treatment regimen. Seventy-five per cent of respondents were not adhering fully to their drug regimen; the mean number of days that respondents had been off drugs was 3.57 days the preceding month. Reasons for non-adherence included: physical discomfort (side effects); non-availability of drugs at treatment site; forgetting to carry drugs during the day; fear of social rejection; treatment being a reminder of HIV status; and selling of own drugs to those unable to enrol in the projects. Being female, under 35 years, single, and having higher educational status were significantly associated with non-adherence. It is important that policy makers and programme managers address the factors responsible for non-adherence when scaling up subsidized ARV treatment in Nigeria and other parts of sub-Saharan Africa
