Annette N. Brown, PhD International Initiative for Impact Evaluation, 3ie Presentation for the HIVST satellite session sponsored by WHO IAC, Melbourne, July 2014 FIVEStudies on HIV Self-testing in Kenya: What We Learned From and About Formative Research
3ie HIV self-testing grants program • Fund pilot programs using HIV self-tests accompanied by impact evaluations • Test for both intended positive outcomes and unintended negative outcomes • Implement country by country (3 countries) • Start with Kenya (12/2012) • Formative research • Impact evaluations
Formative research themes • Accuracy • Packaging and labeling • Potential users and messaging • Distribution outlets • Linkage to counseling and care • Potential social harms and abuses
Methods • Four of five studies used medium to large sample surveys, three of these used random sampling • One study used small sample qualitative data collection • Heterogeneous samples, but not population representative samples • Studies employed basic statistical analysis and some qualitative analysis • One of five used actual self tests as part of study • Our summary analysis is primarily narrative • Most summary findings include evidence from more than one formative study
Formative research findings • Do people want it? • Why? Why not? • Who? • Does it work? • Where would people get it? • Will people get counseling and/or care? • What are people worried about? • How can we address concerns?
Do people want it? • 5/5 studies report near universal “acceptability”: >90% • 3/5 studies report acceptability among never tested: 80% - 91% • FSW: 98% • MSM: 57%
Do people want it? • One study [3] • Men • Never tested would like to be tested: 70% • Never tested would purchase and use if available: 86% • Women • Never tested would like to be tested: 58% • Never tested would purchase and use if available: 80% • Another study [1] • Men never tested who would use a self-test: 90%
Who would use it? • Ever been tested more likely [2] [3] • Men more likely [3]
Does it work? • Sensitivity: 92.9% (89.7%) • Unobserved sensitivity in US: 91.7% • Specificity: 97.8% (98.0%) • Invalids: 15% (men and never tested more likely) [5]
Where would people get it? Table 6: Percent distribution of survey respondents who would use HIV oral self-test kits by main preferred distribution channels [1]
Where would people get it? Table 8: Percent distribution of survey respondents who would use HIV oral self-test kits by other preferred distribution channels apart from the main one mentioned [1]
What are people worried about? 70.7% of men and 54.9% of women feel there are disadvantages [3] • Might commit suicide • Anxious or depressed (men more than women) • Not disclose (men more than women) • Harm others (men more than women) • Counterfeit kits (men more than women)
What are people worried about? 66.2% of men and 54.7% of women feel that self-testing would be misused or abused [3]
What would people do? What would people do if positive? [3] • Seek counseling: 41.4% | 35.8% • Confirm results: 22.0% | 19.5% • Seek medication: 10.7% | 18.9% • Go into depression: 9.0% | 8.3% • Keep results secret: 4.8% | 2.2% … • Commit suicide: 1.9% | 1.6% • Intentionally infect others: 0.2% | 0.0%
Messaging findings • Mass media sensitization and awareness campaigns • Come from MOH • Inform: address concerns and advantages • Educate: importance of confirmatory test, disclosure, linkage to care, prevention • Prior to and during roll-out [2]
Packaging and labeling findings • Packaging secure • Small size • Labeling—with quality seals, informative • Improved instructions—simple, explicit • Information about storage, expiration • May require point of distribution instruction [4]
Linkage to care findings • Strong desire for face-to-face counseling [3] • Telephone hotline not preferred [3] • Public health facilities strongly preferred for counseling before and after [1]
Main conclusions • High acceptability and likelihood of use • Accuracy not much different from US • Health facilities are a desirable outlet • Perceptions of disadvantages and abuses do exist • Big differences between men and women • Mass messaging important • Packaging and labeling important
What did we learn about formative research? • Sensitivity of findings to question formats and choices listed • High occurrence of priming • Useful, but no substitute for impact evaluation of pilot programs
