Background and context
Linkages across the Continuum of HIV Services for Key Populations Affected by HIV Project (LINKAGES), is a five-year cooperative agreement funded by the United States Agency for International Development (USAID) under the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), and implemented by FHI360 in collaboration with PACT, IntraHealth International, and the University of North Carolina at Chapel Hill. LINKAGES aims to accelerate the ability of governments, organizations working with key populations at risk of HIV, and private-sector providers to plan and implement services that reduce HIV transmission among key populations and their sexual partners and extend the lives of those already living with HIV.

LINKAGES project partners were collecting individual-level outreach, testing and referral data using paper-based forms and occasionally unstructured documents (journals. notepads, scraps of paper, etc.). The reliance on paper-based data collection tools and the use of unstructured documents, creates room for errors, and omissions, which makes data susceptible to compliance risks.

Implementation
We began by adapting the existing paper-based peer educator daily diary, and HTC form to electronic format for use by peer educators and counselors on mobile phones to collect outreach and testing data.

An electronic version of the standard paper-based form (Livro de registo de ATSc) used nationally for reporting against HIV testing and counseling was adapted for MDC, and deployed to the phones for use in the field.

Unique Identifier Code
Unique identifier codes (UIC) allow KP to be identified by either a set of alpha-numeric codes or other unique property of that individual that can be used to match related records for that individual only. In general, UICs fit into two broad categories, non-biometric and biometric.

To enable peer educators quickly and easily construct a client-generated UIC, we integrated in the electronic form, a set of simple prompts
Province code (From map on the left)
Prompt 1 mother’s maiden name
Prompt 2 father’s middle name
Prompt 3 Sex
Prompt 4 Year of birth
Prompt 5 Birth order
