Challenges and opportunities for healthcare workers in a rural district of Chad

Trained healthcare workers are an essential resource for effective health systems. However, healthcare workers' perspective on healthcare, the challenges they face to provide quality health services, and opportunities to improve motivation and providing adequate care are rarely investigated in resource-constrained settings of sub-Saharan Africa.; All reachable nurses of Abou Deia, a primarily rural district in the south-eastern part of Chad, were invited to participate. In-depth interviews were conducted to assess current challenges and opportunities faced in daily work, including factors that influence motivation and social wellbeing. Particular emphasis was placed on paediatric care.; Eight nurses were interviewed. Main work challenges pertained to overall workload, a lack of training and support regarding a serious case mix to be managed on their own, adverse working conditions, issues related to the local communities, and the impact of postings on nurses' private life. Poor working conditions and perceived lack of recognition emerged as the main demotivating factors. Motivation to improve nurses' skills so that they can provide good care, coupled with small, suggested changes in working conditions and health care organisation provide opportunities worth exploring to improve health workers' satisfaction, motivation and the care they can provide.; Health workers in a predominantly rural district in Chad face a wide variety of challenges, and hence their perspectives need to be taken into account to improve health services interventions that aim at enhancing quality of care. Nurses' willingness to further develop skills and knowledge, proactive search of solutions to remedy stock-outs of drugs and other medical devices, and motivational factors to improve the quality of care represent important opportunities for improving health services for all

The spatial and seasonal distribution of Bulinus truncatus, Bulinus forskalii and Biomphalaria pfeifferi, the intermediate host snails of schistosomiasis, in N'Djamena, Chad

There is a paucity of epidemiological and malacological data pertaining to schistosomiasis in Chad. In view of a recently articulated elimination agenda, a deeper understanding of the spatio-temporal distribution of schistosomiasis intermediate host snails is pivotal. We conducted cross-sectional malacological surveys during the dry season (April/May 2013) and after the short rainy season (October 2013) in N'Djamena, the capital of Chad. Snails were identified at the genus and species level using morphological keys and molecular DNA barcoding approaches. Those belonging to Bulinus and Biomphalaria were examined for cercarial shedding. Snail habitats were characterised and their predictive potential for the presence of schistosomiasis intermediate host snails explored. Seasonal patterns were studied using geographical information system and kriging in order to interpolate snail abundance data to make predictions at non-sampled locations across N'Djamena. Overall, 413 Bulinus truncatus, 369 Bulinus forskalii and 108 Biomphalaria pfeifferi snails were collected and subjected to cercarial shedding. During the dry season, one Bu. truncatus of 119 snails collected shed Schistosoma spp. cercariae (0.84%), while S. mansoni was shed by one of 108 Bi. pfeifferi snails (0.93%). None of the snails collected after the rainy season shed Schistosoma spp. cercariae. The abundance of Bu. truncatus and Bu. forskalii showed an inverse U-shape relationship with the square term of conductivity, i.e. low abundance at the lowest and highest levels of conductivity and high abundance at intermediate levels. Bi. pfeifferi showed a negative, linear association with pH in the dry seasons. It is planned to link these intermediate host snail data to infection data in human populations with the goal to draw a predictive risk map that can be utilised for control and elimination of schistosomiasis in N'Djamena

The use of mobile phones for demographic surveillance of mobile pastoralists and their animals in Chad : proof of principle

Demographic information is foundational for the planning and management of social programmes, in particular health services. The existing INDEPTH network surveillance sites are limited to coverage of sedentary populations. Including mobile populations in this approach would be expensive, time consuming and possibly low in accuracy. Very little is known about the demography of mobile pastoralists and their animals, so innovative approaches are urgently needed.; To test and evaluate a mobile demographic surveillance system for mobile pastoralist households, including livestock herds, using mobile phones.; Mobile pastoralist camps were monitored (10 for 12 months and 10 for 18 months) using biweekly mobile phone calls with camp leaders and their wives to conduct interviews about the households and livestock. The collected information was validated through personal visits, GPS data and a livestock demographic model.; The study showed the feasibility of mobile phone surveillance for mobile pastoralist camps, providing usable, valid information on human and livestock population structures, pregnancy outcomes and herd dynamics, as well as migration patterns. The approach was low-cost and applicable with the existing local resources.; Demographic surveillance in mobile populations is feasible using mobile phones. Expansion of the small-scale system into a full mobile demographic surveillance system is warranted and would likely lead to improved planning and provision of human and animal health care
