Impact of primary healthcare providers’ initial role security and therapeutic commitment on implementing brief interventions in managing risky alcohol consumption: a cluster randomised factorial trial

Table 2 Impact of baseline role security and therapeutic commitment on the relative per cent difference in the proportion of patients receiving an intervention during the 12-week study period between providers that received the implementation component and providers that did not receive the implementation component

Implementation component	Basic model: brief intervention proportion difference (95 % CI; p value)^a		Basic + RS + TC: brief intervention proportion difference (95 % CI; p value)^a
Training and support (TS)	60.4	(14.5–124.8; 0.007)	62.5	(15.9–127.9; 0.005)
Financial reimbursement (FR)	68.8	(20.5–136.6; 0.003)	67.4	(19.4–134.7; 0.003)
e-BI	4.9	(−25.1–47; 0.78)	5.8	(−24.5–48.3; 0.741)
TS plus FR	170.7	(68.7–334.6; <0.001)	172.0	(69.3–337; <0.001)
TS plus e-BI	68.3	(4.1–172.2; 0.034)	71.9	(6.2–178.4; 0.028)
FR plus e-BI	77.1	(10.6–183.7; 0.018)	77.1	(10.6–183.7; 0.018)
TS plus FR plus e-BI	184.1	(59.2–407.0; 0.001)	187.8	(61.2–414; <0.001)
