Supervisor's Coverage Tool for school-based STH and community-based LF in Philippines

To determine the feasibility and best practices of using the Supervisor's Coverage Tool to monitor community and school-based distribution and integrated MDA.

The Supervisor’s Coverage Tool (SCT) is a rapid, simple, and inexpensive tool designed for use in Neglected Tropical Diseases (NTD) programs mass drug administration (MDA) to monitor drug coverage and compliance, to supervise community drug distributors (CDD), and to identify areas that may need mop-up. After successfully piloting the SCT in Ethiopia and Nigeria in 2015, additional testing of the tool was suggested to assess the feasibility of the tool in different regions and new settings. Therefore, the SCT was implemented in the Philippines in July 2016.

After the completion of training, the field work was conducted in two provinces, in six Supervision Areas (SA) consisting of one or more puroks (subdivisions) per barangay (village). Two survey populations were represented in the SCT implementation covering a community-based distribution for Lymphatic Filariasis (LF), excluding children aged 5-18 years and a school-based distribution for LF for all children aged 5-18 years. 

Findings and lessons learned:

  • The most common reasons for not swallowing drugs were fear of side effects, not feeling well, forgetting, being too busy, and the taste of the medicine.
  • When an accurate register of all the households in the SA exists, it is possible to complete the SCT in each SA in less than a day because the registers greatly aid the random selection process.
  • Implementing the SCT during the last week or two of the MDA was advantageous as it enabled the program to implement the action plan to improve the current MDA using the personnel, budget, and infrastructure that was already in place for the MDA.
  • It is important to consider whether or not Community Drug Distributors (CDD) should accompany the SCT teams during interviews, as their presence may influence the answers of the respondents.
  • It is strongly recommended that when possible, CDDs use directly observed treatment (DOT). If DOT is not possible, CDDs should remind participants that there is no advantage in delaying swallowing the drugs, and that it is actually better when everyone swallows the drugs at the same time.
  • Overall, the Philippines SCT pilot was a success, as it was the first time it was implemented in the Western Pacific region, and it was also used to monitor multiple distributions (both school- and community-based).

Development of Mobile Reader Application at Point-of-care for POC-CCA

Develop a mobile reader application for use at the point-of care for the POC-CCA assay used for mapping and surveillance of Schistosoma mansoni. The reader apk will provide results consistent with the visual human reading of the test. Distinguishing intensity bands and reading 'Trace' results can be problematic and leads commonly to 'false positive' readings. The apk being developed will utilize a testing algorithm to better distinguish between true positive and false positive "Trace" test results.

Evaluation of the Short Term Impact of MDA on Prevalence and Intensity

The purpose of this study is to determine differences between cure rates vs re-infection levels.  The fundamental question is to see what the prevalence and intensity are before MDA, and then, see what those are 7 to 8 weeks after MDA.  Since there are villages that continue to have high prevalence from year to year, we will determine if this primarily represents reinfection occurring since the last annual MDA or if it is related more to treatment efficacy.

Persistent Hot Spots for Schistosoma mansoni Transmission in Western Kenya

A selected number of 5 villages near Lake Victoria shown to maintain very high levels of infection with S. mansoni following at least three rounds of annual praziquantel chemotherapy will be compared with 5 villages where infection rates have been much more responsive to similar levels of treatment, with respect to the following general considerations and questions:

1) What is the general situation for each village with respect to proximity of water bodies where intensive human contact occurs?

2) For each village, what is the role of each major habitat in transmission, as assessed by three separate techniques: water filtration; use of sentinel mice; and standard snail survey techniques?

mHealth Platforms - Operational Research to optimize approaches to improve data flow and accounting

Determine the best data-capture system and implementation model to overcome data flow challenges faced by national MDA programs. Test and compare the effectiveness of 4 different data-tracking platforms currently in use (or development) in NTD endemic countries: 1) Build on existing national capacity, 2) Cloud-based SMS system, 3) Robo-call platform.

Preliminary study findings:

o The current process for tracking treatment information through paper-based forms can be complicated and leaves room for human error, as multiple aggregations of data must be collected manually between administrative levels before reaching the national level. 

o This study found that the process of collecting and reporting paper records on the stock and delivery of ivermectin, albendazole and Praziquantel took between two and three months. 

o The study found that robo-call surveys have the potential to add a new stream of information on drug stock between national supervisors and sub-district implementation teams, allowing program staff to take corrective actions in response to issues with drug supply.

o The proactive timing of the calls as well as the interactive component of responding to verbal questions through the phone makes this system useful to supervisors. 

o Robo-calls were found to be helpful to monitor drug levels prior to MDA at sub-district level and to ensure appropriate quantities of drug stock were reaching lower administrative level, but as post-MDA drug stock is returned to the district level, physical observation of district-level storerooms was the most effective way to assess drug quantities post-MDA.  

o SMS reporting made data accessible at the national level and to administrative units in real time. 

o Less than half of the registered supervisors submitted SMS reports, resulting in a significant difference in the number and type of treatments reported when compared to paper forms. 

o Greater training and ongoing management is needed to take full advantage of the speed and data accuracy improvements from robo-call and SMS surveys.
