| Study characteristics | ||
| Methods | Design: 3‐group cluster‐randomized controlled trial Setting: GPs practising in the Western Metropolitan Region of Sydney, Australia Recruitment: GPs recruited patients in practice |
|
| Participants | 75 practices 82 providers 755 patients (255 people who currently smoked): 49% F, av.age 52; av. cpd not reported |
|
| Interventions |
Intervention 1: • General practitioners received an education guide and a video to help them assess individual patient risk factors and plan a program for risk factor behavior change • Participants received a risk factor assessment, education materials, a series of videos to watch on lifestyle behaviors Intervention 2: as per Intervention 1. In addition, participants received a self‐help booklet (not relevant to this review) Control: GP training and standard care. No further details reported |
|
| Outcomes | Undefined abstinence at 12m Validation: None |
|
| Funding Source | This work was funded by the General Practice Evaluation Program, Commonwealth Department of Human Services and Health, Australia | |
| Author's declarations of interest | Not reported | |
| Notes | Strategy: Provider training & video education Level: Patient and provider Type: Active vs. active (isolates video education) Multirisk factor study Data subgrouped and not unable for the whole sample. Attempts to contact authors unsuccessful, so data are not presented |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Sequence Generation | Unclear risk | No details reported |
| Allocation concealment | Unclear risk | No details reported |
| Blinding of outcome assessors All outcomes | Low risk | Smoking status was self‐reported. The interventions were in the form of a video or a combination of a video and written material so face‐to‐face contact was similar in the routine care group and 2 intervention groups |
| Incomplete outcome data All outcomes | High risk | At participant level, the overall loss to follow‐up was 36.1% (n = 273/757); 49.0% (n = 125/255) in the routine group, 26.3% (n = 71/270) in the video group and 33.2% (n = 77/232) in the video and self‐help group. Altough the number lost to follow‐up was less than 50%, losses were different between groups and some clusters were lost in all groups (5 GPs in the routine group and 4 GPs in the video+self help group) |
| Recruitment bias (cluster RCTs only) | Low risk | Participants were affiliated with the practice before randomization |
| Balanced baseline characteristics? (cluster RCTs only) | Unclear risk | No details reported |
| Adjustment for clustering in analysis? (cluster RCTs only) | High risk | QUOTE: "...No adjustment was made for clustering effects" |
