Hospital-based nurses (N?=?1,790) from three states reported their interventions to help patients quit smoking. Frequency of nurses' interventions in one low tobacco use state, California (n?=?651), were compared to nurses' interventions in two high tobacco use states, Indiana (n?=?720) and West Virginia (n?=?419). Nurses in California were significantly more likely to Advise smokers to quit (OR 1.34, 95% CI [1.06, 1.69]) and Refer smokers to a Quitline (OR 2.82, 95% CI [1.36, 5.88]) compared with nurses in the high tobacco prevalence states. Other aspects of their interventions did not differ by state. Quitline referral was infrequent (16%) but was quadrupled if nurses arranged for smokers to quit (OR 4.07, 95% CI [3.11, 5.32]).
