Case Study

A 27-year-old patient, R.C., with a history of generalized anxiety disorder presents for a wellness examination. R.C. previously smoked a pack of cigarettes per day but has cut down to half a pack per day and started using electronic cigarettes (e-cigarettes) and is interested in eventually quitting the use of tobacco products. R.C. has no other significant medical history, takes no medications, and has an intrauterine device (IUD) for contraception. Physical examination findings are within normal limits.

Case Study Questions

1. Based on the U.S. Preventive Services Task Force (USPSTF) recommendation, which of the following behavioral interventions are effective options for R.C.?

  • A. Nurse advice, which includes a verbal stop smoking message, print materials, and a one-month follow-up visit.

  • B. Hypnotherapy for a minimum of 120 minutes, delivered over four or more sessions.

  • C. Group-based counseling facilitated by a smoking cessation specialist, delivered over six sessions.

  • D. Telephone counseling during scheduled calls, following an initial call to a smoking quit line, to take place over four months.

2. According to the USPSTF, which one of the following statements about the use of e-cigarettes for tobacco cessation is correct and should be shared with your patient?

  • A. e-Cigarettes have been definitively shown to increase tobacco cessation in adults.

  • B. e-Cigarettes are typically used only in the short term when used for tobacco cessation.

  • C. The harms associated with e-cigarette use are well known and minor because nicotine is the only toxic substance emitted.

  • D. The current evidence is insufficient to assess the balance of benefits and harms of e-cigarettes for tobacco cessation in adults, including pregnant persons.

3. R.C. is interested in IUD removal because R.C. and their partner would like to conceive. Based on the USPSTF recommendation, which one of the following statements about pharmacotherapy for tobacco cessation in pregnant persons is correct?

  • A. Trials of bupropion sustained-release (Zyban) or varenicline (Chantix) pharmacotherapy during pregnancy did not show an increase in cessation.

  • B. Clinicians should consider the severity of tobacco dependence in each patient and engage in shared decision-making to determine the best individual treatment course.

  • C. Nicotine replacement therapy (NRT) has been definitively shown to be effective for tobacco cessation in pregnant persons.

  • D. Pharmacotherapy for tobacco cessation in pregnant persons should be offered only after the first trimester of pregnancy.

Answers

1. The correct answers are A, C, and D. The USPSTF concludes with high certainty that the net benefit of behavioral interventions and U.S. Food and Drug Administration–approved pharmacotherapy for tobacco smoking cessation, alone or combined, in nonpregnant adults who smoke is substantial1 (see Table 4 in the USPSTF recommendation statement). Most combination interventions include behavioral counseling involving several sessions (four or more), with planned total contact time usually ranging from 90 to 300 minutes. Effective behavioral interventions include physician or nurse advice, individual or group counseling, telephone counseling, and mobile phone–based interventions. Physician or nurse advice is often given in a single session lasting less than 20 minutes, with up to one follow-up visit within three months. Advice generally includes a verbal stop smoking message and is often given with print materials, additional advice from health care staff, or a referral to a cessation clinic. Individual or group-based counseling delivered by smoking cessation specialists typically includes review of smoking history and motivation to quit, help in the identification of high-risk situations, and the creation of problem-solving strategies. Individual counseling sessions are often face-to-face or via telephone with multiple follow-up sessions. Group-based counseling is typically delivered over six to eight sessions. Telephone counseling and mobile phone–based interventions are generally tailored to patients' smoking history and readiness to quit, focusing on increasing motivation and likelihood of quitting. They vary from two weeks to one year, with most taking place over three to four months, and can include automated text messages. Only limited evidence is available on hypnotherapy for tobacco cessation, so it is not included in recommended tobacco cessation interventions by the USPSTF.
