Physician smoking cessation counseling and adherence to the Clinical Practice Guideline

Objective: The U.S. Public Health Service Clinical Practice Guideline recommends that physicians provide tobacco cessation interventions to their patients at every visit. While many studies have examined the extent to which physicians implement the guideline’s “5 A’s”, few studies have examined the extent to which physicians implement the guideline’s “5 R’s” which are to be used in a Motivational Interviewing (MI) consistent style with smokers not ready to quit. This study examined the extent to which physicians in usual practice and without specific training administered the 5 R’s including the use of an MI style.Methods: Thirty-eight physicians were audio recorded during their routine clinical practice conversations with smokers.Recordings were coded by independent raters on the implementation of each of the 5 A’s, 5 R’s and MI counseling style.Results: Results revealed that for patients not ready to quit smoking, physicians most frequently discussed the patient’s personal relevance for quitting and the risks of smoking. Roadblocks and rewards were discussed relatively infrequently. MI skill code analyses revealed that physicians, on average, had moderate scores for acceptance and autonomy support, a low to moderate score for collaboration and low scores for empathy and evocation.Conclusion: Results suggest that for the Clinical Guideline to be implemented appropriately physicians will need specialized training or will need to be able to refer patients to counselors with the necessary expertise of counseling efforts could increase providers’ willingness to implement guideline recommendations.

Brief Physician-Initiated Quit-Smoking Strategies for Clinical Oncology Settings: A Trial Coordinated by the Eastern Cooperative Oncology Group

Purpose: Although tobacco use by cancer patients increases the risk of relapse, diminishes treatment efficacy, and worsens quality of life, about one third of patients who smoked before their diagnosis continue to smoke. Because patients have regular contact with oncologists, the efficacy of a physician-based smoking cessation treatment was evaluated. Methods:Cancer patients (n = 432) were randomly assigned to either usual care or a National Institutes of Health (NIH) physician-based smoking intervention. The primary outcome was 7-day point prevalence abstinence at 6 and 12 months after study entry. Results: At the 6-month follow-up, there was no significant difference in quit rates between the usual care (11.9%) and intervention (14.4%) groups, and there was no significant difference between the usual care (13.6%) and intervention (13.3%) groups at the 12-month follow-up. Patients were more likely to have quit smoking at 6 months if they had head and neck or lung cancer, began smoking after the age of 16, reported at baseline using a cessation self-help guide or treatment in the last 6 months, and showed greater baseline desire to quit. Patients were more likely to have quit smoking at 12 months if they smoked 15 or fewer cigarettes per day, had head and neck or lung cancer, tried a group cessation program, and showed greater baseline desire to quit. Finally, there was greater adherence among physicians to the NIH model for physician smoking treatment for patients in the intervention versus the usual care group. Conclusion: While training physicians to provide smoking cessation treatment to cancer patients can enhance physician adherence to clinical practice guidelines, physician smoking cessation interventions fail to yield significant gains in long-term quit rates among cancer patients.
