Smoking cessation after acute myocardial infarction: effects of a nurse-managed intervention.

Author information

  • 1Stanford University School of Medicine, California.

Abstract

STUDY OBJECTIVE:

To determine the effect of a nurse-managed intervention for smoking cessation in patients who have had a myocardial infarction.

DESIGN:

Randomized, with a 6-month treatment period and a 6-month follow-up.

SETTING:

Kaiser Foundation hospitals in Redwood City, Santa Clara, Hayward, and San Jose, California.

PATIENTS:

Sequential sample of 173 patients, 70 years of age or younger, who were smoking before hospitalization for acute myocardial infarction. Eighty-six patients were randomly assigned to the intervention and 87 to usual care; 130 patients (75%) completed the study and were available for follow-up.

INTERVENTION:

Nurse-managed and focused on preventing relapse to smoking, the intervention was initiated in the hospital and maintained thereafter primarily through telephone contact. Patients were given an 18-page manual that emphasized how to identify and cope with high-risk situations for smoking relapse.

MEASUREMENTS AND MAIN RESULTS:

One year after myocardial infarction, the smoking cessation rate, verified biochemically, was 71% in the intervention group compared with 45% in the usual care group, a 26% difference (95% CI, 9.5% to 42.6%). Assuming that all surviving patients lost to follow-up were smoking, the 12-month smoking cessation rate was 61% in the intervention group compared with 32% in the usual care group, a 29% difference (95% CI, 14.5% to 43.5%). Patients who either resumed smoking within 3 weeks after infarction or expressed little intention of stopping in the hospital were unlikely to have stopped by 12 months.

CONCLUSIONS:

A nurse-managed smoking cessation intervention largely conducted by telephone, initiated in the hospital, and focused on relapse prevention can significantly reduce smoking rates at 12 months in patients who have had a myocardial infarction.
