Table 3 Measures of association between participant characteristics and primary healthcare centre characteristics and the outcomes (adherence to guidelines) in primary healthcare centres in two counties in northern Sweden, 2007, obtained from analyses

From: Associations between workplace affiliation and phlebotomy practices regarding patient identification and test request handling practices in primary healthcare centres: a multilevel model approach

Measures of variation PHC Always ask patient to state name and civic number Never neglect asking for ID with the reason “known” Always compare pat ID with ID on test request Always make sure test request and test tube label ID numbers are consistent
