Tools for Streamlined and Standard Durability Monitoring

Before implementing durability monitoring (DM), it is important to understand which approach will best fit the specific country context. A Streamlined DM approach should be considered for implementation in countries that have already collected previous rounds of DM data and are primarily interested in evaluating bioefficacy and ITN physical integrity, particularly for new types of nets. Information from previous DM activities or other country-specific context can be used to identify sites. A Standard DM approach should be implemented where there is no or limited country data on ITN durability available. Study tools for this approach are available lower down on this page. For both types of approaches the cost and sample frame will depend on the number of sites and types of ITNs monitored. A typical study includes two sites. PMI supported the development of Streamlined Durability Monitoring in 2020/2021.

Summary of the Differences between Streamlined and Standard Durability Monitoring

Streamlined Durability Monitoring Package

The President’s Malaria Initiative (PMI) Insecticide Treated Net (ITN) Streamlined Durability Monitoring Package is available for countries primarily interested in evaluating bioefficacy and physical integrity of ITNs, and where previous rounds of standard durability monitoring have been conducted. Study materials and tools are related to study design, implementation, and data collection.

Standard Durability Monitoring Package

The President’s Malaria Initiative (PMI) Long-Lasting Insecticidal Net (LLIN) Durability Monitoring Package comprises two parts. Part 1 includes materials and tools related to study design, study implementation and data collection, up through the data entry stage. Part 2 includes materials and tools for data cleaning, preparation, analysis, and interpretation, including reporting.

Part 1: Introduction and Data Collection

Last updated: July 10, 2019 – PPS cluster sampling tool, PPS cluster sampling tool example, sampling frame data example, DM design, sample size, and cluster selection PowerPoint, and generic ODK forms and do-files for ODK form preparation.

Previous Updates:

March 7, 2019 – Revised pre and post test with answer key added. 36m report template with dummy tables added.

November 15, 2018 – guidelines on submission of data and for transitioning durability monitoring to a new implementing partner were added. Baseline bioassays added as standard. Activity manual added. Interpretation of results added.

May 5, 2017 – Stata do-files for baseline and 12-month data analysis added. 12- and 24-month report and figures templates updated.

October 24, 2016 – Updates to protocol and PMI guidance made to accommodate an option for tagging a separate cohort of bioassay nets at baseline instead of selecting them from neighboring households. One-page questionnaire for bioassay nets added in English, French, and Portuguese. Minor edits were made to the Data Preparation do-files to correct an error. Sample Training Agenda was updated. File 4b, a list of supplies and materials for training and fieldwork, was added.

September 1, 2016 – Complete set of OpenDataKit (ODK) forms and media files added as file 2j.ii, in all languages and for all assessments.

August 24, 2016 – Full set of survey questionnaires added/updated. Baseline, 12/24 month, and 36-month questionnaires each available in English, French, and Portuguese, with annotations where customization is required. These are minimal updates, including a new question (q38b) on seasonal net use, an addition of an answer option for why a net was removed from the household (q80), and harmonization of the list of LLIN brands across surveys and languages (q112).

August 13, 2016 – Part 2 tools added (do-files, baseline reporting templates). Printable barcode labels file and net median survival tool added.
