Background: To control and eventually eliminate vivax malaria, radical treatment with primaquine (PQ) is essential after completion of blood-stage treatment. Although in many malaria-endemic countries, village health volunteers (VHVs) are engaged in diagnostic treatment of malaria in remote communities, they principally provide blood-stage treatment. In such a situation, access to PQ following blood-stage treatment can be a barrier to complete treatment. However, studies on access to PQ treatment have been scarce and limited in health facility-based settings. This study aimed to identify factors associated with access to PQ treatment in rural Papua New Guinea (PNG) from the community case management perspective. Methods: A community-based, cross-sectional survey was conducted to collect sociodemographic information on children under 15 years of age, their households, and their caretakers in East Sepik Province, PNG. Data collection lasted from February to March, 2015. Information on the diagnoses of potential non-falciparum malaria and prescription of PQ in preceding year (January to December 2014) were obtained from child health-record books. Then, multilevel logistic regression model was used to determine the factors associated with formal health facility visits for PQ treatment among children with potential non-falciparum malaria. Results: Of 420 episodes diagnosed as potential non-falciparum malaria, 46 (11%) were immediately given PQ. The rest were instructed to visit formal health facilities (HFs) for PQ, and the patients obtained PQ during the second visit to HFs was 44%. Consequently, the overall proportion of PQ prescription was 50%. Logistic regression analysis suggested that among the patients who were instructed to visit HFs for PQ treatment, the initial visit to VHV and higher transportation costs to HF were inversely associated with PQ prescription during the second visit to an HF. Conclusions: Few children received PQ treatment during the second visit to HFs following diagnosis of potential non-falciparum malaria. These findings suggest a need to establish a policy to reduce structural and economic barriers and improve rural inhabitant access to PQ treatment. [ABSTRACT FROM AUTHOR]

Background: Little is known about the association between the social capital of village health volunteers (VHVs) and their performance in relation to malarial care., Methods: Data came from 337 children and 13 VHVs working in Dagua, Papua New Guinea. The outcome variable was whether caretakers brought their children to health care services on the incidence of a febrile episode. The social capital of VHVs was assessed by inquiring about relationships with people in 25 social positions/roles., Results: Caretakers were more likely to bring their febrile children to health care services when they lived in a village whose VHVs frequently discussed their activities with people in positions/roles outside their village (prevalence ratio [PR]=1.47 [95% confidence interval {CI} 1.22 to 1.78]). On the other hand, caretakers were less likely to do so when their VHVs had known people in informal positions/roles inside their village (PR=0.85 [95% CI 0.77 to 0.93]) and when they discussed their activities with people in formal positions/roles inside their village (PR=0.76 [95% CI 0.61 to 0.95])., Conclusions: Our results suggest that the social interactions of VHVs with people in positions/roles outside the village may benefit residents while those with people in positions/roles inside the village might not necessarily benefit them., (© The Author(s) 2018.
