Incremental effectiveness of cessation interventions
| Intervention element | Data source | Increase in % of smokers abstinent for 6 months or longer |
|---|---|---|
| Very brief advice to stop (3 min) by clinician versus no advice | AHCPR | 2 |
| Brief advice to stop (up to 10 min) by clinician versus no advice | AHCPR | 3 |
| Adding NRT to brief advice versus brief advice alone or brief advice plus placebo | Cochrane | 6 |
| Intensive support (e.g. smokers’ clinic) versus no intervention | AHCPR | 8 |
| Intensive support plus NRT versus intensive support or intensive support plus placebo | Cochrane | 8 |
| Cessation advice and support for hospital patients versus no support | AHCPR | 5 |
| Cessation advice and support for pregnant smokers versus usual care or no intervention | AHCPR | 7 |
Note: The incremental cessation rate is the difference between the % successful in the intervention and control groups (percentages rounded).
