Economic analysis of the diabetes and hypertension screening collaboration between community pharmacies and a Thai government primary care unit

AimsTo evaluate models for collaboration between community pharmacies and a government primary care unit (PCU) in carrying out a screening program for diabetes and hypertension.MethodsAn action research was undertaken and a screening and referring protocol developed. Study sites were two community pharmacies (Model 1) and footpaths/streets and seven communities (Model 2) under supervision of PCU in the city of Maha Sarakham Province, Thailand. The Combined Model consisted of Models 1 and 2. Those eligible were aged 40 years and over, not known to have diabetes or hypertension. Activity based costing of three models was analyzed from the provider perspective.ResultsThe study involved 456 people during July–September 2007; 11 out of 51 attending pharmacies (21.6%) and 27 out of 405 attending the communities (6.6%) met criteria for referral to PCU for confirmatory diagnosis. Only six attended the PCU. Two of 456 (0.4%) were confirmed the diagnosis having hypertension, one was referred from a pharmacy (2%, 1/51) the other from a community (0.2%, 1/405). Model unit costs were US$ 11.2, 4.3 and 5.1 per screened person, respectively.ConclusionsThe results indicate a working model can identify people in the community requiring treatment of hypertension or diabetes. Pharmacy-based screening was more costly, but the success rate for referral was higher compared with a community-based service. More effort is needed to ensure referred patients attend the PCU.
