World No Tobacco Day – except to make malaria drugs

May 31st marks World No Tobacco Day. The Theme for 2017 is “Tobacco – a threat to development.” According to WHO, “Tobacco control has been enshrined in the Sustainable Development Agenda. It is seen as one of the most effective means to help achieve SDG target 3.4 of a one-third reduction globally, by 2030, of premature deaths from  noncommunicable diseases (NCDs).” Control is also associated with positive environmental and anti-poverty outcomes.

It is ironic then that the tobacco plant itself may be modified to produce life saving anti-malarial medicines. Nature reported that because Artemisia annua produces a precursor of the compound, artemisinic acid, only in low quantities, it is expensive to grow.  Consequently, “a team led by Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam-Golm, Germany, inserted genes for artemisinic acid synthesis into tobacco plants’ chloroplasts — abundant organelles that have their own DNA. By adding ‘accessory genes’ that make artemisinic acid production more efficient, they created a line that pumps out 120 milligrams of artemisinic acid per kilogram of biomass.”

Science magazine followed up to report that although “several years ago researchers transplanted the drugmaking genes into yeast, allowing them to collect the compound from a microbial brew, the fermentation process is still relatively expensive.” Tobacco, on the other hand, is an “inexpensive, high-volume crop.” Inserting the right genes into tobacco, they noted, would enable “harvesting artemisinic acid from a plot of land 200 square kilometers—less area than a city the size of Boston—would provide enough artemisinin to meet the entire worldwide demand.”

Malhotra et al. discovered another novel approach that found that, “Partially purified extracts from the leaves of transgenic tobacco plants inhibited in vitro growth progression of Plasmodium falciparum-infected red blood cells. Oral feeding of whole intact plant cells bioencapsulating the artemisinin reduced the parasitemia levels in challenged mice in comparison with commercial drug. Such novel synergistic approaches should facilitate low-cost production and delivery of artemisinin and other drugs through metabolic engineering of edible plants.”

Another approach looks at malaria vaccines. Beiss et al. note that malaria “transmission blocking vaccine (TBVs) need to be produced in large quantities at low cost.” They found a high level  transient expression in fresh leaves of Nicotiana benthamiana of an effective TBV candidate. Likewise Jones et al. demonstrated the potential of the new malaria vaccine candidate and also support feasibility of expressing Plasmodium antigens in Nicotiana benthamiana.

The American Cancer Society observed that most African Countries are in the early stages of the tobacco epidemic. This may be a good time to switch the production of tobacco on the continent from purveyor of cancer and NCDs to a ‘factory’ for producing malaria medicines. The sooner this can be done, the better since artemisinin  resistance is a growing threat.

Ghana – spotlight on malaria indicators

The Demographic and Health Surveys has released a brief on key indicators from the Ghana Malaria Indicator Survey of 2016. While much of the malaria community is discussing the elimination framework and processes, the reality is that many high burden countries are still trying to scale up basic interventions to achieve universal coverage.

The overall prevalence across the country in children aged 6-59 months at the time of the survey was 27% using Rapid Diagnostic test and 20% using microscopy.  Among children reporting fever in the previous two weeks care/advice was sought for only 72%. Although only only 30% received some sort of blood based diagnostic test, 61% of the febrile children were given the antimalarial artemisinin-based combination therapy drugs.

Children are still being treated without the benefit of parasitological testing, a key procedure highlighted in WHO case management guidelines. Presumptive treatment for malaria without testing means that a child could inappropriately receive antimalarial drugs and die of another underlying febrile illness. Appropriate testing and adherence to test results is one of the main areas of focus of Ghana’s grants from the US President’s Malaria Initiative. Improved testing is also an important element in Ghana’s current Global Fund support. Clearly more value for money is needed from these inputs.

Preventive measures as documented in the MIS fare somewhat better., but at present only 73% of households own an insecticide treated bednet. When considering the recommended 1 net for every 2 household members, the indicator drops to 50%. Concerning the typical ‘vulnerable’ populations, we see that only 52% of children below the age of 5 years slept under an ITN the night before the survey; only 50% of pregnant women did likewise.

Malaria prevention in pregnancy results reflect the fact that Ghana has promoted at least three IPTp doses for around ten years. Most pregnant women (78% ) had received the previously recommended minimum of two doses, and now 60% have received at least three doses.

One of the important issues stressed in WHO’s new malaria elimination framework is stratifying the country by prevalence to the lowest level possible in order to plan appropriate interventions. Fortunately the Ghana 217 MIS key indicator brief does stratify prevalence and intervention coverage by region.  Prevalence through RDT testing ranges from nearly 5% in the urbanized greater Accra area to 44% in the Central Region. Interestingly ITN use is nearly 20% higher in Central than greater Accra.

Hopefully future planning in Ghana will build on this stratification. Better mobilization of donor, national and private sector resources will address likely issues of stock-outs and increase the likelihood of universal coverage of basic interventions that is needed to move the country along the road to malaria elimination.

Rwanda Celebrates World Malaria Day 2017 – community is a major focus

Dr. Noella Umulisa, the Malaria Team Lead or the USAID Maternal and Child Survival Program in Kigali Rwanda shares with us experiences from Rwanda’s recent observance of World Malaria Day 2017.

The Malaria Day celebration took place in Huye districts in the southern Province. Why the southern province? – because among the 10 high endemic districts, 6 are the southern province. Why Huye district? – because IRS has been launched in Huye district yesterday and in another district Nyanza in Southern province.

The ceremony was attended by USAID and WHO representative, local leaders, MOH staff, partners, population of Simbi sector and the guest of honour was Dr Jeannine Condo the Director General of Rwanda Biomedical Center (which houses malaria activities).

A special recognition was given to community health workers (CHWs) who are playing a key role and are on the front line of fighting Malaria through sensitization of the population, testing and treating the population through community case management (iCMM and HBM) of Malaria, and now when a big number of CHWs will be involved in spraying households in their community.

The World Malaria Day celebration in Rwanda is marked by different activities for Malaria prevention conducted at community level from 24th to 29th April 2017.  Also, Malaria prevention and control messages are being disseminated using different communication tools and approaches such as radio and TV programs, community outreach activities, educating communities on proper use of bed nets.

Door to door mobilization is being conducted about the Indoor Residual Spraying (IRS) in high malaria burden districts of Huye and Nyanza. MCSP, with support from the US President’s Malaria Initiative, has participated actively in this event by supporting Community outreaches though theatre skits in the first 10 high endemic district.

The Director General made the following statement:

In January 2016, the Government of Rwanda and partners developed a Malaria Contingency Plan in response to the increase in malaria cases. The following interventions were implemented to address malaria rise in Rwanda: A Home Based Management of fever for adults at community level was set up countywide to reduce the malaria burden and prevent severe malaria and death. From Nov 2016 up to March 2017, the country distributed more than 6 million nets in 30 districts ensuring universal coverage of the entire population.

The country has increased access to health services for all through Community Based Health Insurance (CBHI). The Government of Rwanda provides free treatment of malaria to the most vulnerable population (Ubudehe 1&2 categories) to ensure that all financial barriers are no more to hinder the health service delivery for the community. Extension of Indoor residual spraying (IRS) in districts with high malaria burden where 5 out of 8 were sprayed (Nyagatare, Kirehe, Bugesera, Gisagara and Gatsibo).

We hope that this commitment will keep Rwanda on track to control and eventually eliminate malaria.

World Health Workers Week, a Time to Recognize Health Worker Contributions to Malaria Care

Since the beginning of the Roll Back malaria Partnership in 1998 there has been strong awareness that malaria control success is inextricably tied to the quality of health systems. Achieving coverage of malaria interventions involves all aspects of the health system but most particularly the human resources who plan, deliver and assess these services. World Health Worker Week is a good opportunity to recognize health worker contributions to ridding the world of malaria.

We can start with community health workers who may be informal but trained volunteers or front line formal health staff.  According to the Frontline Health Workers Coalition, “Frontline health workers provide immunizations and treat common infections. They are on the frontlines of battling deadly diseases like Ebola and HIV/AIDS, and many families rely on them as trusted sources of information for preventing, treating and managing a variety of leading killers including diarrhea, pneumonia, malaria and tuberculosis.”

The presence of CHWs exemplifies the ideal of a partnership between communities and the health system. With appropriate training and supervision CHWs ensure that malaria cases are diagnosed and treated promptly and appropriately, malaria prevention activities like long lasting insecticide-treated nets are implemented and pregnant women are protected from the dangers of the disease. CHWs save lives according to Nkonki and colleagues who “found evidence of cost-effectiveness of community health worker (CHW) interventions in reducing malaria and asthma, decreasing mortality of neonates and children, improving maternal health, increasing exclusive breastfeeding and improving malnutrition, and positively impacting physical health and psychomotor development amongst children.”

CHWs do not act in isolation but depend on health workers at the facility and district levels for training, supervision and maintenance of supplies and inventories. These health staff benefit from capacity building – when they are capable of performing malaria tasks, they can better help others learn and practice.

A good example of this capacity building is the Improving Malaria Care (IMC) project in Burkina Faso, implemented by Jhpiego and supported by USAID and the US President’s malaria Initiative. IMC builds capacity of health workers at facility and district level to improve malaria prevention service delivery and enhance accuracy in malaria diagnosis and treatment. Additionally capacity building is provided to health staff in the National Malaria Control Program to plan, design, manage and coordinate a comprehensive malaria control program. As a result of capacity building there has been a large increase in malaria cases diagnosed using parasitological techniques and in the number of women getting more doses of intermittent preventive treatment to prevent malaria during pregnancy.

Malaria care is much more than drugs, tests and nets. Health worker capacity is required to get the job done and move us forward on the pathway to eliminate malaria.

Myanmar – update on malaria indicators

Myanmar is one of the countries at the epicenter of the developing resistance of malaria parasites to artemisinin based drugs. This means there is a strong need for prompt, appropriate and thorough diagnosis and treatment of febrile illnesses and malaria as well as the regular use of effective malaria preventive technologies. The 2015-16 Demographic and Health Survey for the country is thus a timely source of information to improve malaria interventions. Highlights from the DHS follow.

The first major concern is both lack of insecticide treated nets as well as low use of those available as the pie chart from the DHS makes clear. Ironically 97% of households have some kind of net, but 73% do not have an insecticide treated one. Although the Global Fund has supported distribution of 4.3 million ITNs in the country, there are over 56 million people living there. The US President’s Malaria Initiative has procured nearly 900,000 ITNs for the country. Although low across all economic strata, the lowest wealth quintile have the highest ITN possession (35%).

The 2013 concept note submitted by Myanmar to Global Fund under the new funding mechanism identifies many of the challenges: “Factors that may cause inequity to services for treatment and prevention: There are several population groups, which are poorly served by the health system and malaria services such as those living in remote border areas, migrant populations, forest workers and miners where malaria transmission is intense. Many of them are internal and external migrants who usually have limited access to malaria prevention and control. Major factors include distance from health facilities and poor awareness of malaria and its prevention.”

Key strategies in the Global Fund Concept Note do address quality malaria diagnostics and appropriate treatment. Unfortunately DHS results do not yet show the impact of improved diagnosis and treatment. “Overall, 16% of children under age 5 had a fever in the 2 weeks before the survey. Advice or treatment was sought for 65% of these children with recent fever, and 3% had blood taken from a finger or heel, presumably for diagnostic testing.” A variety of public and private sources were used to seek fever treatment, but “Only 1% of children received antimalarial drugs for treatment of fever in the 2 weeks preceding the survey.”

In addition to formal donors, there are coalitions and consortia who provide encouragement, technical assistance, advocacy and capacity building for eliminating malaria in the Asia-Pacific region. While the country needs to take stronger leadership in malaria elimination, all groups need to come together and strengthen the malaria interventions in Myanmar as these have implications for eliminating the disease in the region as a whole.

Leadership and Support for Malaria Pre-Elimination in Nepal

Emmanuel Le Perru, Jhpiego field staff in Nepal, shared his experiences in aiding the malaria pre-elimination efforts in the country during a retreat that preceded the 65th Annual Meeting of the American Society of Tropical Medicine and Hygiene in Atlanta. Here are some highlights of his talk.

risk-mapMalaria Pre-Elimination efforts are targeting 0 deaths as well as investigation of 100% of confirmed cases in Nepal. Systematic entomology investigation/interventions are required. Glucose-6-Phosphate Dehydrogenase deficiency (enzyme genetic defect causing hemolysis with primaquine) testing for Plasmodium vivax in high G6PDd prevalence communities is required. Cases should receive treatment within 72 hours of symptoms for Pf (to quickly prevent transmission and gametocyte reservoir). There is also a need to distinguish between indigenous and imported cases.

Jhpiego is providing technical assistance and capacity building for Nepal’s Ministry of Health pre-elimination efforts as follows:

  • Integrated Vector Management
  • Micro-stratification
  • Entomology curriculum to be conducted in medical college (need new positions)
  • Case-based Surveillance guidelines
  • Private-sector engagement (for increased reporting and product quality control/procurement such as Antigen RDTs)
  • Capacity Assessments in 9 health systems strengthening components at central and district levels (Jhpiego Malaria Implementation Guide)
  • Human resources: clear job descriptions and performance goals
  • Leadership & Management development program

gfatm-bednets-distProgram highlights include the fact that the Global Fund malaria grant rating improved from B2 (inadequate but demonstrating potential) in January 2016, but now A2 (meeting expectations) in November 2016. Concept note for operational research at 2 or 3 border check points has been developed in order to determine whether such intervention (communication & voluntary screening) is cost-effective and relevant to catch/target imported cases, raise awareness on malaria available services, detect/prevent sources of potential outbreaks. This will inform GFATM on the relevance to fund such intervention. A similar approach was done at the China-Myanmar border but was not recognized by not WHO.

Nepal's Global Fund Grant Indicators for Malaria Case Management

Nepal’s Global Fund Grant Indicators for Malaria Case Management

Although the National Malaria Strategic Plan refers to high risk groups (forest workers, national parks security personnel, refugees, prisoners, etc.) evidence is needed to back this up. A study or improved investigation forms are needed to identify such groups and use this information to design appropriate behavior change communications and other interventions.

Special Programming Highlights include proposing a focus on Closed/Isolated Settings/Foci (limited migration, duration and population) to WHO and GFATM. Considering a targeted mass drug administration (MDA) Plasmodium vivax (not yes recommended by WHO) with Primaquine/G6PD testing. Consideration is being given to new drugs in the pipeline such as Ivermectin. Molecular Testing using Polymerase Chain Reaction (PCR) to detect low parasitemia, asymptomatic or re-infection cases (Pv includes inactive/dormant sporozoites known as hypnozoites) is being proposed.

Community based testing as proposed in the Global Fund grant needs strengthening. Therefore RDT use by Female Community Health Volunteer is being considered. Active case detection is another possibility for those areas moving toward pre-elimination. As mentioned, there is also need for studies of asymptomatic infection.

Lessons learned so far for best practices for efforts in identifying specific pre-elimination interventions include the value of getting consensus at national level through the Malaria Technical Working Group. There is also need to challenge WHO recommendations and engage dialogue to get creative. At present there is a risk of a Catch 22 situation wherein the GFATM asks for innovative interventions but at the same time tries to adhere strictly WHO to existing guidance.

The Nepalese malaria program is in constant dialogue with the GFATM Fund Portfolio Manager and team on the local context and technical challenges in order to get them involved in looking for innovative solutions.

Challenges arise in malaria diagnostics. While systematic microscopy is the gold standard, quality can be poor because of low stain/re-agent quality, constant staff turnover and donor reluctance to fund additional training. Also microscopy confirmation and slide quality control are time consuming, and often this process is not clear or well followed. PCR require specific equipment, training and qualifications. Takes time to be operational.

There are opportunities moving forward.  Progress could be made if there were more “elimination experts” to position to influencer to WHO to seek and propose new interventions for the pre-elimination stage. Nepal provides an ideal opportunity to test new ideas. It will also be necessary for the national malaria program staff to receive regular technical updates on program issues such as new drugs (Ivermectin?) and on-going pilots of MDA.

A Pilot to Use Malaria RDTs at the Community Level in Burkina Faso

A poster entitled “The Improving Malaria Care (IMC) Project’s Contribution to follow up a Pilot to Use Rapid Diagnostic Tests (RDTs) at the Community Level in Burkina Faso” was presented by members of Jhpiego’s Burkina Faso Team: Ousmane Badolo, Stanislas P. Nebie, Moumouni Bonkoungou, Mathurin Dodo, Rachel Waxman, Danielle Burke, William Brieger at the 65th annual meeting of the American Society of Tropical Medicine and Hygiene in Atlanta. The abstract follows …

CHWs provide malaria testing, treatment and health education

CHWs provide malaria testing, treatment and health education

Early and correct case management of malaria in health facilities and at the community level is among the priorities of Burkina Faso’s National Malaria Control Program (NMCP). In line with this initiative, the NMCP piloted use of Rapid Diagnostic Tests (RDTs) by Community Health Workers (CHWs) to confirm malaria cases in the three health districts of Kaya, Saponé and Nouna between 2013 and 2015. With PMI support, follow-up visits were organized to document best practices, as well as challenges, on RDT use by CHWs that could serve as lessons learned for scale-up.

During follow-up visits, malaria commodities management (supply, storage and use) at the community level was examined, use of RDTs was assessed, and implementation at the community stockoutlevel was discussed with all actors at regional, district, health facilities, and community levels. The team examined the monitoring/supervision processes at all levels, used a check list on malaria commodities management, and employed a questionnaire for each type of actor. Both qualitative and quantitative data have been collected. A total of 108 persons were contacted including 32 CHWs, 42 community leaders and 34 health care providers and managers.

chw-drug-kitFindings revealed frequent stock-outs of RDTs and artemisinin-based combination therapies, non-payment of stipends to CHWs (a demotivator) and insufficient supervision of CHW by health teams. From the community perspective, 66% of community leaders were satisfied with their CHW’s work (diagnosis and treatment of uncomplicated malaria concernsand referral of severe cases to health facilities). However, 46% of community leaders complained of frequent stock-outs and unanimously agreed on the importance of regular payment of premiums to CHW.

Follow up of the pilot was valuable in obtaining community, CHW and health worker perspectives for improving the program. While the community finds the program acceptable, its sustainability will require that solutions be found for stock-outs, non-payment, and insufficient supervision before scale up takes place.

Preventing Malaria Drug Resistance in the African Setting …

and Dealing with it Should Resistance Occur

Professor Joseph Ana, Africa Centre for Clinical Governance Research & Patient Safety in Calabar, Nigeria shares his experiences and concerns in this blog.

Drug resistance is one of the biggest challenges facing health care systems in the world today. Around 25,000 people die each year from resistant viral and bacterial infections in Europe, but no new classes of antibiotics have come on the market for more than 25 years. The figures are difficult to obtain for Africa and other developing countries.

Medicine shops may sell inappropriate malaria medicines, thus contributing to resistance

Medicine shops may sell inappropriate malaria medicines, thus contributing to resistance

Drug resistance is considered important in the failure of control and treatment of diseases its consequences, and it is considered to be one of the causes of emergence of new strains of infective organisms and re-emergence of once-controlled diseases. The occurrence and impact of the phenomenon is worse in Africa and parts of Asia for malaria according to WHO and the US CDC. Viral and bacterial diseases are also affected in this region.

Therefore, there is urgent need for global sustained action to prevent drug resistance from happening, and to control it, if it happens. The causes of Drug resistance are varied including lack of or poor implementation of the control of access to drugs, population migration and movement, misdiagnosis, under-treatment and irrational drug prescription and use.

Global Report malaria drug resistanceTo prevent drug resistance, countries need to legislate and implement adequate control of access to drugs, sustain public education on the dangers of drug resistance, educate health workers on and enforce rational drug prescribing and use. Effective monitoring of treatment outcomes is also important to know when drug resistance is occurring. With the global and country by country best efforts drug resistance may still occur because of mutation and adaptation of infective organisms.

For diseases like Malaria for which resistance to the most effective drug today, artemisinin-combination drugs, is being reported from Southeast Asia, the development of new drugs alongside vector control is essential by all countries, particularly in Africa.

Tanzania – Malaria Indicators Low, Still Need Work

Success in the war against malaria is not guaranteed. Two articles to that effect have appeared The Citizen of Dar es Salaam following presentation of findings from the most recent (2015-16) Tanzania Demographic and Health Survey (DHS)/Malaria Indicator Survey (MIS).

Slide2On Tuesday (21 June 2016) the news story noted the increase in malaria prevalence among children below the age of 5 years, which was attributed to “the decline in the use of mosquito nets and low distribution of nets to households.” Then in a Wednesday (22 June 2016) Editorial, the paper noted that this “backtracking” is a “worrisome situation, for malaria is a problem that puts such a heavy burden on the government and the country’s economy.”

Slide1A look at the preliminary DHS does confirm the concerns about insecticide treated nets (ITNs).  After nearly 10 years of progress, reported ITN availability in households declined. This was reflected in a drop in reported use by children below 5 years of age as well as pregnant women. It should be noted that targets set in 2000 in the Roll Back Malaria Abuja Declaration had been 80% by the year 2010, and those had almost been achieved in 2012, but the fall to around 50% in 2015-16 is discouraging.

Another preventive measure has also faced difficulty. Pregnant women should receive doses of Sulfadoxine-pyrimethamine (SP) as part intermittent preventive treatment (IPT) during antenatal care (ANC).  Until 2012 the recommendation was two contacts, but the World Health Organization has raised this to three or more depending on the number of times a woman attends ANC. So far IPT has not reached 40% or half of the Abuja target.

Slide3This low IPT coverage is ironic since most women attend ANC at least once in Tanzania. At present only 68% of women who had been pregnant received the first dose of IPT even though 98% registered for ANC. Granted that some may have registered in their first trimester when they would not yet be eligible for IPT, but the gap is quite large and signals missed opportunities, which are often caused by stock-outs. Even though the proportion of women attending up to ANC visits could be better, these attendances should produce better delivery of the 3rd IPT dose.

Slide4Malaria can also be controlled through prompt and appropriate treatment. While testing and treatment of children with appropriate artemisinin-based combination therapy (ACT) has increased, this are is still problematic. In particular, while WHO recommends that all cases of fever should be tested, less than a third received a test (rapid diagnostic test – RDT or microscopy). Testing helps distinguish malaria from other fevers, and ACTs should not be given unless malaria is confirmed. We can see that more ACTs are provided than the number who were tested, so treatment based solely on signs and symptoms is still the norm. Again there is need to explore the availability of both RDTs and ACTs as factors that have made these targets difficult to achieve.

Tanzania continues to receive support from the Global Fund and the US President’s Malaria Initiative, among other partners. It is incumbent on all partners, global and national, to use these results as a wake up call to to plan for better delivery of malaria services and thus a reduction of both the economic and health burden of malaria in Tanzania.

 

An Ideation Model: Attitudes, Beliefs and Practices Relevant to Malaria Prevention and Treatment in Madagascar and Liberia

Stella Babalola, Nan Lewicky, Grace Awantang, Michael Toso, Hannah Koenker, Arsene Ratsimbasoa, Monique Vololona of the Johns Hopkins Center for Communication Programs and the Division for Malaria Control, Madagascar Presented findings on how local perceptions help predict uptake of malaria interventions at the 143rd American Public Health Association Annual Meeting, October 31 – November 4, 2015, in Chicago. Their presentation on Liberia and Madagascar is summarized below.

While Liberia has an average malaria parasitemia prevalence of 28%, malaria is considerable less common in Madagascar and varies by region and altitude. This difference provides an interesting opportunity to observe similarities and contrasts in community perceptions of the disease.

Slide6Theoretical basis of the research is based on the Ideation model which has been described as follows and as seen in the attached figures:

  • “New ways of thinking and the diffusion of those ways of thinking by means of exposure to mass media and social interactions in local, culturally homogeneous communities” – Kincaid, 2000
  • “views and ideas that people hold individually” – van de Kaa 1996

Slide7The ideation model has successfully predicted current use of a contraceptive method as well as accessing childhood immunization. The team took up the challenge to learn whether this model would be applicable to malaria interventions.

Malaria-related ideation was proposed to consist of: Malaria knowledge (cause, symptom, prevention); Perceived susceptibility to malaria; Perceived severity of malaria; Perceived self-efficacy to prevent malaria; and Social interactions about malaria. These may lead to uptake of malaria interventions.

Slide10Items for measuring bed net ideation could include – knowing where to procure a bed net, Willingness to pay for bed net, Having a positive attitudes towards bed net (derived from ten attitudinal statements), Perceived response-efficacy of bed nets, Perceived self-efficacy for procuring and using bed nets, Participation in household decisions about bed nets, Descriptive norm about bed net use and Social interactions about bed net use.

Percent of female caregivers that slept under an ITN on the night before survey increased by level (score) of bed net ideation as seen in the graph. Results (odds ratio) of logistic regression of sleeping under an ITN on bed net ideation and other covariates showed a similar trend.

Slide15Intermittent Preventive Treatment of Malaria in Pregnancy ideation measures included the following:

  • Knows name of the drug for malaria prevention during pregnancy
  • Knows the timing of first dose of IPTp
  • Has positive attitudes towards ANC and IPTp (derived from four attitudinal statements)
  • Perceived response-efficacy of IPTp
  • Woman participates in decisions about own health
  • Social interactions about malaria and pregnancy
  • Descriptive norm about ANC visits

Slide21The percent of women who took at least two doses of IPTp during their most recent pregnancy also increased by level of IPTp ideation Likewise the results (odds ratio) of logistic regression of obtaining at least two doses of IPTp on IPTp ideation and other covariates were highest among those with highest levels of ideation.

Items for measuring case management ideation included –

  • Perceived response efficacy of malaria diagnostic test
  • Perceived self-efficacy for detecting uncomplicated malaria
  • Perceived self-efficacy for detecting severe malaria
  • Descriptive norm about prompt treatment of malaria in children
  • Social interactions about malaria treatment
  • Participation in household decisions about child health
  • Positive attitudes towards appropriate malaria treatment

Slide27Again the percent of children sick with fever in past two weeks who received prompt ACT treatment by caregiver’s increased with increasing level of treatment ideation. As before the results (odds ratio) of logistic regression of prompt ACT treatment on caregiver’s treatment ideation and other covariates shows highest levels of ideation were associated with greated treatment seeking.

The team concluded that the same ideation model with demonstrated validity for family planning, child immunization, WASH and other health behaviors is relevant for malaria prevention and treatment. Strategically designed messages and interventions addressing ideational variables can help foster adoption of health-protective malaria prevention and treatment behaviors.

The authors acknowledge The US President’s Malaria Initiative (PMI) for technical guidance on the implementation of the surveys and The Ministry of Health and Social Welfare in Liberia and the Ministry of Health in Madagascar for their collaboration on the surveys.
