Table 2. Evolution of the Haiti Master Health Facility List

Version	Date	Host	Edits/Additions	Comments
Pre-earthquake	Before 2010	The HSIS list was available online through the HSIS website.	Last updated in 2009.	No entity served as a repository for an MHFL. The HSIS became the basis for the MHFL, but it was incomplete; it did not cover the non-public sector and had variable reporting from the 750 public health facilities in it.
1	January 29, 2010	PAHO	Information on health facilities from the HSIS was merged with other lists creating a total of +/- 1,260 records. The 2009 HSIS health facility list included the following fields: rank (a number assigned to the facility according to when it was created in the commune); name of the department, district, and commune where the facility is located; name of the facility; category (e.g., dispensary, hospital); and type (public, private, or mixed).	Information sources included: HSIS, MESI, USAID, PAHO, PEPFAR, UNOCHA, the Sahana Foundation, MINUSTAH, and Ushahidi.
2	February 9, 2010	PAHO	7 new health facilities were added.
3	February 12, 2010	PAHO	New fields were added for damage and operational status information; 39 new health facilities were added (including field hospitals); and 41 duplicate records were removed.
4	February 16, 2010	PAHO	63 new health facilities were added; 19 duplicate records were removed; and metadata was updated.
5	February 26, 2010	PAHO	HealthC_IDs (unique identification codes) were added to facilities that previously lacked one.	All HealthC_IDs from version 4 remained unchanged, but changes were made to the algorithm used to generate new unique identifiers in the metadata (Supplementary Appendix).
6	March 11, 2010	PAHO	Region, commune, and department IDs in the MHFL were matched to the MSPP_2010 list; official facility names were added; inaccurate values for the various codes used by the MSPP were corrected; geocodes of numerous MSPP sites were corrected; and about 20 duplicate records were removed. This version included all 2010 MSPP health facilities.	New information received post-earthquake from MEASURE Evaluation on behalf of the Haitian MSPP was incorporated into the new MHFL.
7	March 18, 2010	PAHO. Stewardship transferred to Shoreland, Inc., in April 2010, and version 7 was republished on Shoreland's Travax system.¹⁷	50 duplicates were removed and more than 80 new health facilities were added. CATEGORIE, TYPE, and SANTE_ID fields were updated with the latest information from the MSPP.	When the list was republished on the Travax site,¹⁷ a field for cholera treatment centers was added.
Liste des Institutions Sanitaires	Summer 2011	MSPP	Health facilities and field hospitals can now be uniquely identified. Data are updated and validated through self-reporting from facilities and data collection efforts by the MSPP and partners. Some duplicates and data quality issues remain. The list does not include information on mobile clinics (those that are still operational).	The MSPP incorporated the MHFL for a key input to its routine health information system. The MHFL forms the basis of the Liste des Institutions Sanitaires¹⁹ and is integrated into the MSPP's service delivery and infrastructure database.²⁰^,²¹ It is used on an ongoing basis to measure health service coverage.
