Counseling medical patients about cigarette smoking: a comparison of the impact of training on nurse practitioners and physicians.

Health providers believe that eliminating smoking is an important health promotion goal, but physicians and nurse practitioners may differ in the implementation of that belief. To determine whether nurse practitioners or physicians were more likely to counsel smokers to quit smoking, 12 internal medicine nurse practitioners (100 percent female) and 40 internal medicine physicians (30 percent female) were studied at four San Francisco Bay-area Kaiser Permanente Medical Centers, both before and after training in smoking-cessation counseling. In addition, exit phone surveys of at least 15 smokers per participant were completed as soon as possible following an office visit to the participant (269 nurse practitioner patients; 948 physician patients). It was found that nurse practitioners discussed smoking with patients more often than did physicians (64 percent vs. 50 percent; p less than 0.001), asked patients more often whether they were interested in quitting (49 percent vs. 40 percent; p less than 0.01), distributed more smoking-cessation literature to patients (37 percent vs. 25 percent; p less than 0.001) and made more follow-up appointments about smoking (36 percent vs. 19 percent; p less than 0.001). These differences in counseling behavior between the two groups were not explained by differences in patient characteristics of the two groups. The authors concluded that, given the same training, nurse practitioners are more likely to counsel smokers about quitting than are physicians.
