Evaluating smoking cessation service at an emergency department clinical observation unit.

Abstract

To evaluate the effectiveness of a pilot smoking cessation service in an emergency department (ED) clinical observation unit. A descriptive case series review was undertaken of smoking cessation service patients in the short-stay unit of an acute hospital in Singapore from July 1, 2018, to December 31, 2019. Upon admission, ED nurses screen all patients regarding their current smoking status and implement the 5 A's framework, which involves the steps of Ask-Advise-Assess-Assist-Arrange. Patients in the "contemplation" and "preparation" stages were offered the following components: (1) a bedside counseling session by a pharmacist and (2) a follow-up appointment at an outpatient smoking cessation clinic. Postdischarge follow-up telephone calls at 1, 6, and 12 months were carried out as part of the study data collection to obtain abstinence information. Forty-seven patients were included in the study; the majority were male (n = 41; 87.2%). The median numbers of cigarettes smoked per day at baseline, 1 month, 6 months, and 12 months were 14, 5, 3, and 5, respectively. The overall point-prevalence abstinence rates over the same follow-up time points were 26.5%, 38.7%, and 31.3%, respectively. The proportions of patients lost to follow-up at 1 month, 6 months, and 12 months were 27.7%, 34.0%, and 31.9%, respectively. Given the small sample and high number of uncontactable patients, more research is needed to assess whether the trend toward increasing point-prevalence abstinence rate over time and the trend toward decreasing median number of cigarettes smoked are observed in a larger sample.
