In this study, malaria prevalence and morbidity were monitored in two villages in north-eastern Tanzania – a lowland village and a highland village from 2003 to 2008. Trained village health workers treated presumptive malaria with the Tanzanian first-line anti-malarial drug and collected blood smears that were examined later. The prevalence of malaria parasitaemia across years was monitored through cross-sectional surveys, and was found to decrease in the lowland village 78.4% in 2003 to 13.0% in 2008, while in the highland village, prevalence dropped from 24.7% to 3.1% in the same period. Similarly, the incidence of febrile malaria episodes in the two villages dropped by almost 85%, with a marked reduction in anaemia in young children in the lowland village. According to the study, this decline is likely to be due to a combination of factors that include improved access to malaria treatment provided by the trained village helpers, protection from mosquitoes by increased availability of insecticide-impregnated bed nets and a reduced vector density. If this decline in malaria morbidity is sustained, it will have a marked effect on the disease burden in this part of Tanzania.
Equitable health services
Diabetes and hypertension constitute a significant and growing burden of disease in South Africa. Presently, few patients are achieving adequate levels of control. In an effort to improve outcomes, the Department of Health is proposing a shift to a patient-centred model of chronic care, which empowers patients to play an active role in self-management by enhancing their knowledge, motivation and skills. This study explored patients’ current experiences of chronic care, as well as their motivation and capacity for self-management and lifestyle change. The study involved 22 individual, qualitative interviews with a purposive sample of hypertensive and diabetic patients attending three public sector community health centres in Cape Town. Participants were a mix of Xhosa and Afrikaans speaking patients and were of low socio-economic status. The concepts of relatedness, competency and autonomy from Self Determination Theory proved valuable in exploring patients’ perspectives on what a patient-centred model of care may mean and what they needed from their healthcare providers. Overall, the findings indicate that patients experience multiple impediments to effective self-management and behaviour change, including poor health literacy, a lack of self-efficacy and perceived social support. With some exceptions, the majority of patients reported not having received adequate information; counselling or autonomy support from their healthcare providers. Their experiences suggests that the current approach to chronic care largely fails to meet patients’ motivation needs, leaving many of them feeling anxious about their state of health and frustrated with the quality of their care. In accordance with other similar studies, most of the hypertensive and diabetic patients interviewed were found to be ill equipped to play an active and empowered role in self-care. It was clear that patients desire greater assistance and support from their healthcare providers.
To explore perceptions of malaria and utilisation of insecticide-treated bed-nets after a noticeable reduction in malaria incidence in Zanzibar, the authors of this study conducted 19 in-depth interviews with caretakers of children under five in North A district on the island. They found that awareness of malaria among caretakers was high but the illness was now seen as easily curable and uncommon. The discomfort of sleeping under a net during the hot season was identified as the main barrier to consistent bed-net usage. The main cue to using a bed-net was high mosquito density, and children were prioritised when it came to bed-net usage. Caretakers had high perceived self-efficacy and did not find it difficult to use bed-nets. Indoor Residual Spraying (IRS), which was recognised as an additional means of mosquito prevention, was not identified as an alternative for bed-nets. A barrier to net ownership was the increasingly high cost of bed-nets. The authors call on the government to continue providing bed nets through sustainable and affordable delivery mechanisms.
In this study, researchers evaluated the effect of a community health worker-based, interpersonal communication campaign for increasing insecticide-treated mosquito net (ITN) use among children in Luangwa District, Zambia, an area with near universal coverage of ITNs and moderate to low malaria parasite prevalence. Results indicated that ITN use among children younger than five years old in households with one ITN increased overall from 54 % in 2008 to 81 % in 2010. However, there was no difference in increase between the treatment and control arms in 2010. ITN use also increased among children five to 14 years old from 37 % in 2008 to 68 % in 2010. There was no indication that the community health worker-based intervention activities had a significant effect on increasing ITN use in this context, over and above what is already being done to disseminate information on the importance of using an ITN to prevent malaria infection. Contamination across control communities, coupled with linear settlement patterns and subsequent behavioural norms related to communication in the area, likely contributed to the observed increase in net use and null effect in this study, the authors conclude.
The prevalence of non-communicable diseases (NCDs) is increasing in sub-Saharan Africa. At the same time, the use of mobile phones is rising, expanding the opportunities for the implementation of mobile phone-based health (mHealth) interventions. This review aims to understand how, why, for whom, and in what circumstances mHealth interventions against NCDs improve treatment and care in sub-Saharan Africa. Four main databases (PubMed, Cochrane Library, Web of Science, and Google Scholar) and references of included articles were searched for studies reporting effects of mHealth interventions on patients with NCDs in sub-Saharan Africa. All studies published up until May 2015 were included in the review. Following a realist review approach, middle-range theories were identified and integrated into a Framework for Understanding the Contribution of mHealth Interventions to Improved Access to Care for patients with NCDs in sub-Saharan Africa. The main indicators of the framework consist of predisposing characteristics, needs, enabling resources, perceived usefulness, and perceived ease of use. Studies were analyzed in depth to populate the framework. The search identified 6137 titles for screening, of which 20 were retained for the realist synthesis. The contribution of mHealth interventions to improved treatment and care is that they facilitate (remote) access to previously unavailable (specialized) services. Three contextual factors (predisposing characteristics, needs, and enabling resources) influence if patients and providers believe that mHealth interventions are useful and easy to use. Only if they believe mHealth to be useful and easy to use, will mHealth ultimately contribute to improved access to care. The analysis of included studies showed that the most important predisposing characteristics are a positive attitude and a common language of communication. The most relevant needs are a high burden of disease and a lack of capacity of first-contact providers. Essential enabling resources are the availability of a stable communications network, accessible maintenance services, and regulatory policies. The authors propose that policy makers and program managers consider predisposing characteristics and needs of patients and providers as well as the necessary enabling resources prior to the introduction of an mHealth intervention. They argue that researchers would benefit from placing greater attention on the context in which mHealth interventions are being implemented instead of focusing (too strongly) on the technical aspects of these interventions.
According to this paper, puerperal sepsis is an infection contracted during childbirth and one of the commonest causes of maternal mortality in developing countries, despite the discovery of antibiotics over eighty years ago. Some developing countries have recently experienced increased use of health facilities for labour and delivery care and there is a possibility that this trend could lead to rising rates of puerperal sepsis. Drug and technological developments need to be combined with effective health system interventions to reduce infections, including puerperal sepsis. The authors review health system infection control measures pertinent to labour and delivery units in developing country health facilities. Organisational improvements, training, surveillance and continuous quality improvement initiatives, used alone or in combination have been shown to decrease infection rates in some clinical settings. There is limited evidence available on effective infection control measures during labour and delivery and from low-resource settings. The authors argue that a health systems approach is necessary to reduce maternal mortality and the occurrence of infections resulting from childbirth. Organisational and behavioural change underpins the success of infection control interventions. A global, targeted initiative could raise awareness of the need for improved infection control measures during childbirth.
The re-admission rate and the number of preventable re-admissions in a secondary-level South African hospital were measured to identify factors predictive of re-admission. The admission register for the medical wards at Cecilia Makiwane Hospital (CMH) was used to identify re-admitted patients, whose folders were then reviewed. A comparison group of patients who were not re-admitted was randomly generated from the same register. One in twelve general medical patients was readmitted. Chronic diseases and inadequate patient education and discharge planning accounted for the largest group of re-admissions in older patients. Re-admission of HIV/AIDS patients has generated a second peak in younger individuals, and the impact of the antiretroviral roll-out on admission rates warrants further scrutiny.
This review describes, from a systematic review, the current status of family medicine in sub-Saharan Africa and maps existing evidence of its strengths, weaknesses, effectiveness and impact, and identifies knowledge gaps. Family medicine was first established in South Africa and Nigeria, followed by Ghana, several East African countries and more recently additional Southern African countries. Implementation varies between and within countries. The strengths were found to be having “all- round specialists”, providing mentorship and supervision, and there were positive perceptions of the impact of family medicine. Family medicine was found to be a developing discipline in sub-Saharan Africa. The authors indicate that assessing its impact on the health of populations requires a more critical mass of family physicians and clarity on their position in the health system and their role in universal health coverage.
Since 2002, an estimated 4.7 million long-lasting insecticide-treated nets (LLINs) have been distributed in the Southern Nations, Nationalities and Peoples Region (SNNPR) of Ethiopia among a population of approximately 10 million people at risk for contracting malaria. This study sought to determine the status of current net ownership, utilisation and rate of long-lasting insecticide-treated nets (LLIN) loss in the previous three years. A total of 750 household respondents were interviewed in SNNPR. Approximately 67.5% of households currently owned at least one net. An estimated 31% of all nets owned in the previous three years had been discarded by owners, most of whom considered the nets too torn, old or dirty. Households reported that one-third of nets (33.7%) were less than one year old when they were discarded. These results suggest that the life span of nets may be shorter than previously thought, with little maintenance by their owners. With the global move towards malaria elimination it makes sense to aim for sustained high coverage of LLINs, the authors argue. However, in the current economic climate, it also makes sense to use simple tools and messages on the importance of careful net maintenance, which could increase their lifespans.
