For the relief effort in Haiti it is important to know which hospitals are located where and what their condition is after the earthquake. Immediatelly after the earthquake, the Sahana foundation has prepared a database with hospitals located in Haiti. In a community effort it has been populated with ~ 150 entries.
On the other hand, mappers have been adding hospitals to the OSM database. They traced over satellite imagery and added data from MINUSTAH and from other sources in the public domain.
In the meantime, the Pan Americal Health Orgaization (PAHO/WHO) provides a master list of medical facilities (hospitals, clinics, pharmacies, etc.). Work is currently underway to import this reference dataset into the OSM database.
Hospitals identified by WHO/PAHO
There is huge list of medical facilities (hospitals, clinics, pharmacies, etc.) collected by Pan American Health Organization (PAHO/WHO), see announcement on talk-ht. It has more than 1000 geo located entries. There is a second major advantage: PAHO has assigned a unique hospital id which can be used to refer to the facilities from the OSM database.
- a website pointing to the master list with health facilities
- a GIT repository with the hospital list converted to 25 OSM change files
Data originally from MSPP
The PAHO medical facility list seems to have included the Ministry of Health's (MSPP) "2005 MSPP database with geocodes" as can be seen e.g. here. What was the process of the MSPP database converting/merging into the PAHO database is not clear from the tags / change set information. (Perhaps someone with better information could clarify this?)
Has the data e.g. been tweaked, merged with another data set, vetting in a way or an other, or something else?
Data from Sahana
An initial import of the hospitals to OSM has been done. The Sahana data set is not maintained any more, though, and it isn't updated in the OSM database. During the first import of the PAHO/WHO list care has been taken to match already mapped health facilities from the Sahana data set with the new health facilities from the PAHO/WHO list. The former Sahana data set can be downloaded in various formats from the Sahana website.
CDC/USAID MCH facilities list
"MCH" is an acronym for "Maternal and Child Healthcare". A report was prepared in or after 2003 entitled "PMTCT Baseline Assessment and Planning Template", a product of the CDC and USAID; "PMTCT" refers to "Preventing Maternal To Child Transmission [of HIV]". This report states in Part 10 ("Line list of MCH facilities in country"; pg 19): "No list of health facilities providing MCH services is available." The report provides such a list for the first time. As this is apparently a product of the United States government, we may be free to use it without further inquiry; an e-mail address and author appear in the document properties to which an inquiry might be made if deemed necessary.
A copy of the report has been filed with WebCitation.org (see http://www.webcitation.org/5nIoWpjyz ). The report is being added to wikisource; see PMTCT Baseline Assessment and Planning Template (Haiti).
Ground surveyed data
As of October 2011 there has been significant ground surveying and addition to the OSM database at least by the local mapper group, COSMHA as part of their work with IOM. This data has a focus on the cholera response related health facilities. (Is this better documented somewhere in the wiki??)

Roles of the data sets - comparison
|PAHO/WHO||The PAHO/WHO is the reference dataset for health facilities in Haiti. It provides the semantic unique id for health facilities. Note that this data set includes (at least) the "2005 MSPP database with geocodes".|
|OSM database||The OSM database shall include a replica for the health facilities in Haiti in order to (1) display it on the OSM maps and to (2) make it available in OSM queries.|
|Sahana||As of 2010-02-03 the Sahana database became a less important source for health facilities. The OSM database still links to Sahana entries using the tag sahana_id=* (and sometimes ref:sahana_id=*)but the remaining semantic attributes should be replicas of the PAHO/WHO list.|
|CDC/USAID MCH List||Produced in or after 2003, provides a list of facilities at which maternal and child healthcare services can be found.|
|Tag||Master||Description||How to treat in OSM/Role in OSM|
|paho:id=*||PAHO/WHO||The unique id assigned by PAHO/WHO||Don't edit after first import. Establishes the link to the PAHO/WHO dataset.|
|paho:commune_id=*||PAHO/WHO||Unique identifier of the village/city the facility is located in. This is an ID manged by PAHO/WHO. It doesn't correspond with the OSM object ID of a corresponding village/city.||Don't edit after first import. Will be updated by scripts, if necessary. Do not set to an OSM object id of the respective village/city.|
|paho:department=*||PAHO/WHO||Unique identifier of departement the facility is located in. This is an ID manged by PAHO/WHO. It doesn't correspond with the OSM object ID of a corresponding departement boundary.||Don't edit after first import. Will be updated by scripts, if necessary. Do not set to an OSM object id of the respective village/city. Don't add an is_in:departement=* tag, nominatim should geocode the facility correctly because it knows the departement boundaries in Haiti|
|source:health_facility=*||PAHO/WHO||Refers to PAHO/WHO as source of the data||Set at first import. Don't edit afterwards. Will be updated by scripts, if necessary.|
|sahana_id=ID of the hospital from the Sahana website||ID of the hospital from the Sahana website|
|sahana:name=The name of the hospital as known from the Sahana website||The name of the hospital as known from the Sahana website|
|sahana:address=The address of the hospital as known from the Sahana website||The address of the hospital as known from the Sahana website|
|etc. for other attributes from Sahana|
|health_facility:MCH = yes||in combination with amenity=hospital, this would indicate that the facility offers maternal and child health services; analogous to emergency=yes.|
|health_facility:access = public (or) private (or) mixed public/private||the dataset provides three values for "type" of hospital: Public, Privé, Mixte (Public, Private, Mixed)|
|name:fr=*||the dataset provides names of facilities in French.|
|source:name:fr = CDC/USAID PMTCT Baseline||attribution|
|source:health_facility:MCH = CDC/USAID PMTCT Baseline||attribution|
|source:health_facility:access = CDC/USAID PMTCT Baseline||if access key is provided a value from the data set|
|source_ref:CDC/USAID PMTCT = http://www.webcitation.org/5nIoWpjyz||The word document has been archived at WebCitation.org, providing a permanent url.|
Importing the PAHO/WHO dataset
Version 1 (v1) of the PAHO master list as been imported in 2010-02, see archive page. In five days 1104 health facilities have been imported.
On 2010-03-18, PAHO published version 7 of the master list.
703 facilities have been updated in changeset 4177495.
The PAHO master list introduces a new classification for health facilities. Current OSM map renderers don't render these facilities yet. We would like to get them rendered on the following maps:
|1||Jans map||A special purpose map displaying PAHO health facilities as overlay on the standard OSM slippymap, now possible to change to haiti-best-wms-image|
|2||OSM Haiti Relief Map||The map with haiti specific rendering rules (refugee camps, earthquake damage, etc.)|
|3||The main OSM map||Use amenity=hospital for the Haiti health facilities in general, in a ad-hoc fashion, so that they show, with a red cross and at zoom levels allowing a sufficiently large area to be seen at once, on the map at www.openstreetmap.org, that OSM outsiders are most likely to consult first. (Use the humanitarian data model for health facilities to specify the type if possible.)|
|If this tag is present in v1...||If this tag is present in v3...||...this icon|

How to deal with data problems ?
Problems may include illegal lat/lon coordinates (i.e. 0.0/0.0), or lat/lon coordinates which are clearly off (i.e. a hospital to be located in Port-Au-Prince with lat/lon-coordinates around Jacmel) and duplicate entries.
How to deal with duplicate entries
There are a lot of duplicates in the PAHO/WHO list. Some of them are obvious, even to mappers who aren't familiar with the local situation in Haiti. Others are less obvious and must ultimately be resolved by experts at PAHO/WHO. If you identify duplicate entries
- import them anyway
- create a relation with the following tags:
- note=any note/hint for people who want to resolve the poential conflict
- Add the OSM nodes or ways representing the duplicate health facilities with the role object to the relation.
See this example. It keeps two potentially duplicate facilities in Terreneuve together.
How to deal with other data problems ?
If you identify a problem add it to the object using the tag FIXME=*. We'll generate reports which collect the reported FIXME notes. This relieves you from the burden of submitting individual issues to the PAHO issue list.
You may also consider to report corrections or issues with the form provided by PAHO.
This is a list of potential duplicate entries in the PAHO/WHO master list. They have been identified by OSM mappers during the initial import process.
Do not edit this list. It has been generated automatically from the OSM database. Potential duplicates are managed there as special relations, see this example.
The maintainers of the PAHO list are aware of the duplicates and they are working on eliminating them. Upcoming version of the PAHO master list should include less duplicates. OSM will remove duplicates from its database as soon as they are deleted in the PAHO list.

OSM Xapi Methods to retrieve hospital data
Xapi is the eXtendend Application Programming Interface for accessing OSM data.
Using Xapi query URLs
Paste URL shown below into the "Open location..." dialog accessible from the File menu, then select "Download URL"
To get a .osm file
Paste URL into browser address bar, or click on a "Run it now" links below, then select "Save file..." This .osm file can be opened using the "Open..." dialog accessible from the File menu.
Get all PAHO Health Facilities in OSM
Get all hospitals in Haiti
Ultimately, all hospitals should be represented in the PAHO Health Facilities listings. However, to overcome any gaps or newly placed facilities not yet covered by the PAHO index, this query may be used.
Query by PAHO ID
where you have to replace id with the PAHO Health Facility ID.
Example: This Xapi URL queries for the PAHO Health Facility with ID 9340484: https://xapi.openstreetmap.org/api/0.6/*[health_facility:paho_id=9340484]
Query by hospital name
where you have to replace aname with the name of the PAHO Health Facility ID.
Example: This Xapi URL queries for the PAHO Health Facility with the name DISPENSAIRE DE CAPOTILLE: https://xapi.openstreetmap.org/api/0.6/*[name=DISPENSAIRE DE CAPOTILLE|health_facility:paho_id]
OSM Hospital Report
