Chart reminders increase referrals for inpatient smoking cessation intervention

The purpose of this study was to test the effect of a chart reminder system on referral of inpatients to a hospital smoking cessation intervention pilot program. An A1-B-A2 reversal design was used to test the hypothesis that a chart reminder to nursing staff would increase the proportion of smokers referred for smoking cessation intervention over the usual method of posted memos. In Condition A1, memos reminding nursing staff to refer smokers were posted prominently on a cardiopulmonary unit for 4 weeks. In Condition B, a reminder containing the same message was placed in the front of every patient chart for 4 weeks. Finally, in Condition A2, chart reminders were removed and posted memos were reinstated for 4 additional weeks. During Condition A1 (posted memo), only one patient out of 29 eligible smokers was referred, for a referral rate of 3.4%. In Condition B (chart reminders), 18 patients out of 52 (34.6%) were referred (chi 2 = 10.07, p < 0.01). In Condition A2, the referral rate returned to below baseline (2.1%) (chi 2 = 16.80, p < 0.001). The findings support the use of a chart reminder system for screening and referral as an important component for comprehensive smoking cessation programs in the acute care setting.
