Radley A, Melville K, Tait J, Stephens B, Evans J & Dillon JF (2017) A quasi-experimental evaluation of dried blood spot testing through community pharmacies in the Tayside region of Scotland, Frontline Gastroenterology, 8 (3), pp. 221-228.


Comparison of uptake of dried blood spot testing (DBST) for hepatitis C virus (HCV) infection between community pharmacies and established services. 
Quantitative evaluation of a service development with qualitative process evaluation undertaken in parallel. 
Six pharmacies from 36 community pharmacies within Dundee City, a large urban settlement with high levels of socioeconomic deprivation. 
Patients in receipt of opioid substitution therapy (OST) not tested for HCV within 12 months. The 6 pharmacies provided OST for approximately 363 patients from a cohort of 1385 patients within Dundee City. 
Provision of DBST by pharmacists. 
Main outcome measure
Receipt of DBST between January and December 2014. 
43 of 143 service users with no record of testing from the 6 community pharmacies accepted DBST. Of 561 from the remaining 1022 service users with no record of testing, 75 were tested for HCV (30% vs 13%). The OR for increased uptake of testing within the 6 pharmacies was 2.25 (95% CI 1.48 to 3.41, Z statistic=3.81, p=<0.0001) compared with other services. The DBST taken by the pharmacies provided 12 patients with a reactive test. The process evaluation identified key themes important to staff and recipients of the service. A logic model was constructed. 
Non-experimental service evaluation performed in community pharmacies records service activity in one location across a single time period. 
Some evidence that DBST from community pharmacies may be feasible. Service users received the service positively. Staff reported that DBST was straightforward and achievable.
