title: The Natural History of Smoking Cessation Among Medical Patients in a Smoke-Free Hospital.
abstract: Our purpose was to determine the frequency and predictors of quitting smoking among patients hospitalized on the medical services of a smoke-free hospital. All smokers admitted to the medical services of a single university teaching hospital were eligible and 129 patients were enrolled. A questionnaire detailing demographic information, stages of change, smoking behavior while hospitalized, and intention to remain abstinent on discharge was administered. The primary discharge diagnosis was obtained from the medical record. Patients were followed at 3- and 6-month intervals for continuous abstinence, with expired carbon monoxide confirmation at 6 months. A total of 7% of smoking patients receiving usual medical care were continuously abstinent at 6 months. Of those who relapsed, 45% did so by the time of discharge, 18% within the first week, 20% between 1 week and 3 months, and 10% between 3 and 6 months after discharge. All patients who were abstinent at 6 months had been admitted for coronary artery disease (CAD). Nine of the 38 patients with CAD were abstinent, versus none of 93 with another diagnosis (p <.001). Smokers admitted to a smoke-free hospital had a high rate of relapse, especially early after discharge. Patients admitted for CAD had a greater likelihood of successfully quitting. Designing hospital-based smoking cessation interventions with a focus on early relapse prevention may help improve smoking cessation rates.
