GPS Mapping to Improve Condom Access for MARPs GPS Mapping to Improve Condom Access for MARPs Presentation Transcript

  • GIS and GPS Mapping To Improve  Condom Availability, Access and  Visibility for HIV Prevention Among  FSW in Indonesia  Erlian R. Aditya, FHI 360 Indonesia
  • Acknowledgment • • • • • • • • Prakash Dev Pant, Ph.D., FHI Nepal Anton Schneider, FHI Indonesia USAID Indonesia CSOs in Jakarta, East Java, Papua GIS Team, PAC Jakarta NAC, PAC, DAC in JKT, EJ, Papua PHC, DHO, PHO in JKT, EJ, Papua FHI Indonesia, CSM Team
  • A persistent level of infection and a consistently low condom  use rate among sex workers present a challenge… 50 40 To strengthen the ability to advocate for consistent condom use, it is  important to know the places where hotspot and condom outlets located,  their numbers, distribution,  current ratio between outlet and hotspot and  distance of outlet from hotspot.  30 % 24.2 25 25.5 20 10 10.5 11.6 10.4 0 North Jakarta HIV Prevalence Surabaya Consistent Condom Use Jayawijaya
  • We are curious… • Why is the level of condom use still low? • In addition to behavior changes that are not evenly distributed, what other  factors can lead to low condom use behavior? • We wondered whether condom availability and access is still an issue • A lot of anecdotal data on this, but no solid data on the table. • To address this need, the Geographic Information Systems (GIS) and GPS is  introduced as a pilot in 2012 for periodic mapping of probable hot spots and  assessment of program coverage  • This study monitors and assesses program performance through measures  such as condom coverage, quality of condom coverage and access to condoms  • Study findings are intended to enable evidence based pragmatic decisions: – Focused social marketing and distribution of condoms – Monitoring programmatic performance and ensuring condom availability
  • METHODOLOGY 1 2 3 4 5 6 • Enumerate all hot spots within study area to establish sampling frame GPS • Prepare hot zones as a geographic cluster of hot spots GIS • Determine sample hot zones using systematic random sampling How is the  • Enumerate condom‐selling outlets in sampled hot zones Process? GPS • Calculate condom coverage, quality of coverage and access GIS • Produce maps showing condom coverage and access GIS
  • SATELLITES  •24 Satellites •12 Hour Orbital Period •20,000 km altitude Geographic Information System In short, GIS is a computer based system, capable of holding and using data describing location GPS data is one  of the sources  geographical  data used in  GIS GPS RECEIVERS •Track Code and Phase •Extract Satellite Message •Computes Position Global  Positioning System GROUND STATIONS •Time Synchronization •Orbit Prediction •Satellite Health
  • DATA COLLECTION FORMS Hotspot Mapping Form Condom Outlet Audit Sheet
  • Tools Used GPS ArcMap – GIS Software
  • Pilot Study Sites Jakarta East Java Papua • North Jakarta • West Jakarta • Surabaya • Malang District • Jayawijaya District • Jayapura District and City
  • What We Need To Conduct GIS and GPS Mapping? 1 GIS 5 GPS 5 Interviewers 1 SPSS/PT
  • Operational Definitions Hotspot Hotzone Condom Outlet • Place where sex  negotiation or  sexual activity  takes place • Defined area with  a cluster of hot  spots • Any vendor or  retail seller of  condoms  • Bar, Motel, Massage  Parlor, Discotheque,  Brothel, Karaoke, SPA,  Streets, Parks, Train/  Bus Stations, etc. • Area covering a  minimum radius of  100m • Pharmacy, stall, DIC,  Bars/Karaoke/Disco,  Minimart, PHC, SPA,  Supermarket, etc. 
  • Sample Hotspot
  • Indicator Measured: Condom Coverage Coverage:  A measure of condom availability in and around hot zones.  Measurement:  Ratio of condom‐selling outlet to number of hotspots in a hot zone.  Desired value: A hot zone that maintains a ratio of  one condom selling outlet per five hot  spots,  then the hot zone will be considered as a zone where condom is available
  • Indicator Measured: Quality of Coverage Proportion of outlets in a hot zone where  product/services meet following standards Stocking  condom at  the time of  survey Condom  stocked in  visible  location at  point of  purchase Promotional  material  available in  visible  location at  point of  purchase No condom  out of stock  last month Proportion  of outlets  that sell  condoms at  night
  • Indicator Measured: Condom Access Proportion of hot spots that are situated within 100 meter radius of  a condom selling outlet

  • Overview of  Hotspot and  Hot Zone  Map
  • Map of Hotspot and Outlet in One of Hot  Zone, Surabaya City East Java Province, Surabaya City Need to increase number of outlet in this places
  • Need to increase number of outlet in this places There are 143 hot spots in the West Jakarta, from which 33 Zones were created
  • Map of Hotspot and Outlet in Dolly‐Jarak,  biggest brothel complex in South East Asia Need to increase number of outlet in this places
  • Viewing Our Data in Google Earth East Java Province, Surabaya City, Dolly-Jarak Brothel Complex
  • Hotspot and Outlet Distribution – FSW  Jayapura Condom outlet only available in these area.
  • Hotspot and Outlet Distribution‐ FSW Jayapura (Tanjung Elmo brothel complex) Ideal example where distribution and ratio of  outlet and hotspot met the criteria. 
  • Follow up Activities • Establish more outlets in certain hotspots/hot zones • Establish/strengthen community‐based distribution taskforce in each hot  zone • Develop more condom promotional material for outlets • Provide outlets with condom display material to increase condom visibility • Use condom retail audit sheet for more frequent condom stock out  assessment • Advocate 100% CUP at hot zone and sub‐district level • PAC in 3 provinces planned to scale up GIS mapping to other districts (7  districts) • Conduct second wave GIS mapping
