6. Interventions for improving adherence

The most frequently employed interventions for improving adherence reviewed were NRT, antidepressant therapy, pharmacist intervention, psychosocial/behavioural support and counselling, and diet counselling (low-calorie diet) (see also Table 9). Adjunctive psychosocial treatment or behavioural advice has been successfully used to support smoking cessation programmes (25).

Although Alterman et al. showed that patients receiving more intense adjunctive psychosocial or medical treatment were more adherent to treatment with patches (25), overall, the data reviewed suggested that minimal behavioural support also results in similar or higher adherence rates, at least for some types of smoker. Minimal behavioural support might offer a cost-effective way to implement first-line smoking cessation programmes at a population level. More controlled studies including cost-effectiveness analysis are needed to clarify this issue.

The monitoring of therapeutic drug levels, NRT and/or antidepressant may also be useful. This feedback might be used to identify poorly adherent patients for whom more intensive adherence-enhancing interventions would be helpful (46).

Intensive anti-smoking campaigns, such as the "Truth Denormalization Ads" might be extremely useful, especially among teenagers, as they change the social attitude towards tobacco smoking.

Factors affecting adherence

Interventions to improve adherence

Socioeconomic-related factors

(-) High treatment cost (41)

(+) Higher education levels, older age (41)

Social assistance (25)

Health care team/health system-related factors

(-) Unavailability for follow up or lost to follow up (1,8,10,11,17,21); failure to recall the receipt of a prescription (20)

(+) Access to free NRT; more frequent contact with physicians and pharmacists (35)

Pharmacist mobilization (41); access to free NRT; frequent follow-up interviews (35)

Condition-related factors

(-) Daily cigarette consumption; expired CO, plasma nicotine and cotinine levels; Fagerstrom Tolerance Questionnaire (FTQ) scores (44); greater tobacco dependence (25); psychiatric comorbidities; depression (3,25); failure to stop or reduce smoking during treatment (1,3,8 - 10,17,18,21,22,24,29,36 - 38,41 - 43)

Education on use of medications; supportive psychiatric consultation (3,25)

Therapy-related factors

(+) Attendance at behavioural intervention sessions (26); adverse events (1,9,16,37 - 40) or withdrawal symptoms (1,9,11,12,13,16 - 18,22,35 - 40)

NRT; antidepressant therapy; education on use of medications; adherence education; assistance with weight reduction (29); continuous monitoring and reassessment of treatment; monitoring adherence (46)

Patient-related factors

(-) Weight gain (29)

(+) Motivation (25); good relationship between patient and physician (41)

Adjunctive psychosocial treatment; behavioural intervention (1,9 - 13,16 - 19,21 - 23,25,29,30,32,38,39,47 - 52); assistance with weight reduction (29); good patient - physician relationship (41)

 

CO, Carbon monoxide; NRT, nicotine replacement therapy; (+) factors having a positive effect on adherence; (-) factors having a negative effect on adherence.
