Residents and medical students identified a lack of knowledge regarding Nicotine Replacement Therapy (NRT) as a barrier to smoking cessation counselling. We hypothesized that a teaching session on NRT during an inpatient Internal Medicine rotation would increase learner comfort in prescribing these products. Medical trainees on the Internal Medicine Clinical Teaching Unit (CTU) attended a teaching session during week 4 of an 8-week rotation. Pharmacy records from the 8-week period were retrospectively analyzed to determine NRT prescribing behaviour. Pre-intervention, 5.8% (13/225) of new admissions received a NRT prescription. Post-intervention, 17% (31/182) of new admissions received a NRT prescription. Using a Fisher’s exact test, the percentage of new admissions that received a prescription was significantly different (p<0.001) between the pre- and post-intervention time frames. This data suggests that integrating education on NRT into CTU teaching can significantly alter prescribing behaviour and improve access to NRT for patients who need it.
