BACKGROUND: Papua New Guinea (PNG) introduced a revised national malaria treatment protocol (NMTP) in late 2011. Successful implementation of the revised protocol requires all health facilities in PNG to have reliable access to microscopy or malaria rapid diagnostic kits as well as a reliable supply of all recommended first-line medications. This paper presents findings from a study that sought to assess the availability of microscopy, malaria rapid diagnostic kits and recommended first-line antimalarial medication in Papua New Guinean health facilities across the country before the introduction of the revised treatment protocol. METHODS: A country-wide cross-sectional survey of 79 randomly selected health centres, health subcentres and aid posts. Data were collected via an interviewer-administered questionnaire completed with the officer in charge of participating health facilities. RESULTS: Overall, 15% of surveyed health facilities had unexpired rapid diagnostic test (RDT) in stock or working microscopy available. A recommended first-line antimalarial for uncomplicated malaria was available in 85% of health facilities. The preferred first-line antimalarial combination for treating severe malaria was present in 42% of health facilities, although 68% had the capacity to provide either the preferred or recommended substitute first-line medication for severe malaria. The total number of health workers employed in the 79 surveyed health facilities was 443, only 3 of whom were medical doctors. CONCLUSIONS: Our findings indicate that diagnostic capacity was low in Papua New Guinean health facilities before the introduction of the new NMTP and that access to recommended first-line antimalarial medication was variable. Substantial improvements in diagnostic capacity and antimalarial procurement and distribution will need to be made if the revised protocol is to be adhered to.

Malaria is endemic across lowland Papua New Guinea (PNG) and case management has been based on symptomatic diagnosis and presumptive treatment of fever cases with an antimalarial. This study aimed to investigate the prevalence of malaria infection among fever cases presenting to 5 purposely selected sentinel health facilities in order to estimate the proportion of patients requiring antimalarial drugs. A total of 1807 fever patients were screened. Overall, 45% of fever patients had a positive malaria blood slide; 35% were infected with Plasmodium falciparum, 9% with P. vivax and 2% with P. malariae. Slide positivity was highest in Dreikikir (75%) and lowest in Wipim (2%). Among patients aged 1-4 years, 22% had moderate to severe anaemia (Hb < 8 g/dI) and 21% of children 2-9 years of age showed signs of splenomegaly (Hackett score 1-5). Comorbidity differed significantly between study sites and was not closely correlated with malaria infection. Clinical diagnosis by health facility staff was malaria for 67% of all fever cases, including 89% of slide-positive and 48% of slide-negative patients. 70% of rapid diagnostic test-negative cases were treated with an antimalarial. It is estimated that due to the lack of parasitological diagnosis the selected health facilities reported an excess of 18% (Dreikikir) to 98% (Wipim) malaria patients on average each month. In consideration of the significant differences in malaria-attributable fevers between study sites, the implementation of parasitological diagnosis in health facilities and administration of antimalarials only to test-positive patients has the potential to significantly improve the management of fever cases and reporting of malaria. A better tailoring to different settings may increase the effectiveness of malaria control interventions.

As the last part of a program to survey the extent of malaria transmission in the Papua New Guinea highlands, a series of rapid malaria surveys were conducted in 2003-2004 and 2005 in different parts of Southern Highlands Province. Malaria was found to be highly endemic in Lake Kutubu (prevalence rate (PR): 17-33%), moderate to highly endemic in Erave (PR: 10-31%) and moderately endemic in low-lying parts (< 1500 m) of Poroma and Kagua (PR: 12-17%), but was rare or absent elsewhere. A reported malaria epidemic prior to the 2004 surveys could be confirmed for the Poroma (PR: 26%) but not for the lower Kagua area. In Kutubu/Erave Plasmodium falciparum was the most common cause of infection (42%), followed by P. vivax (39%) and P. malariae (16%). In other areas most infections were due to P. vivax (63%). Most infections were of low density (72% < 500/ microl) and not associated with febrile illness. Overall, malaria was only a significant source of febrile illness when prevalence rates rose above 10%, or in epidemics. However, concurrent parasitaemia led to a significant reduction in haemoglobin (Hb) level (1.2 g/dl, CI95: [1.1-1.4.], p < 0.001) and population mean Hb levels were strongly correlated with overall prevalence of malarial infections (r = -0.79, p < 0.001). Based on the survey results, areas of different malaria epidemiology are delineated and options for control in each area are discussed.

The Global Fund to Fight AIDS, Tuberculosis and Malaria is the major funaer of the National Malaria Control Program in Papua New Guinea (PNG). One of the requirements of a Global Fund grant is the regular and accurate reporting of program outcomes and impact. Under-performance as well as failure to report can result in reduction or discontinuation of program funding. While national information systems should be in a position to provide accurate and comprehensive information for program evaluation, systems in developing countries are often insufficient. This paper describes the five-year plan for the evaluation of the Global Fund Round 8 malaria grant to PNG (2009-2014) developed by the Papua New Guinea Institute of Medical Research (PNGIMR). It builds on a complementary set of studies including national surveys and sentinel site surveillance for the assessment of program outcomes and impact. The PNGIMR evaluation plan is an integral part of the Global Fund grant. The evaluation program assesses intervention coverage (at individual, household and health facility levels), antimalarial drug efficacy, indicators of malaria transmission and morbidity (prevalence, incidence), and all-cause mortality. Operational research studies generate complementary information for improving the control program. Through the evaluation, PNGIMR provides scientific expertise to the PNG National Malaria Control Program and contributes to building local capacity in monitoring and evaluation. While a better integration of evaluation activities into routine systems would be desirable, it is unlikely that sufficient capacity for data analysis and reporting could be established at the National Department of Health (NDoH) within a short period of time. Long-term approaches should aim at strengthening the national health information system and building sufficient capacity at NDoH for routine analysis and reporting, while more complex scientific tasks can be supported by the PNGIMR as the de facto research arm of NDoH.
