The urgency behind the guideline is grounded in stark epidemiology. Cigarette smoking remains the leading cause of preventable death in the United States, contributing to hundreds of thousands of deaths each year through lung cancer, chronic obstructive pulmonary disease, cardiovascular disease, and stroke. Smoking rates are not evenly distributed across the population. They are especially high among individuals of lower socioeconomic status, groups that also tend to face greater barriers to accessing outpatient cessation services, and among hospitalized populations, where smoking-related illness is frequently the very reason for admission. For many patients, a hospital stay represents one of the few sustained contacts they will have with the health care system, making it a uniquely valuable window for intervention.

Despite that opportunity, tobacco treatment interventions remain chronically underutilized in hospitals, even though they rank among the most cost-effective strategies in all of health care. Studies of cessation pharmacotherapy and counseling have repeatedly shown favorable cost-effectiveness profiles compared with many other preventive services, yet the practical machinery of inpatient care, with its emphasis on treating the acute presenting illness, often leaves smoking unaddressed. The new guideline aims to close that gap by giving clinicians a clear, standardized protocol rather than leaving cessation decisions to individual habit or institutional variation.

Lead author Hasmeena Kathuria, MD, framed the guideline as a response to that inconsistency. When a patient is hospitalized, she noted, there is a real opportunity to initiate tobacco treatment. Her hope, she said, is that a standardized approach will help more clinicians feel comfortable providing counseling and pharmacotherapy to all hospitalized patients who smoke unless they explicitly decline, and will support continued treatment after discharge. Implementing these approaches, she added, is likely to improve smoking-cessation outcomes and reduce hospital readmissions, a dual benefit that speaks directly to both public health goals and the financial pressures hospitals face under value-based purchasing programs that penalize excess readmissions.

Among the six recommendations, several stand out for their specificity. The guideline recommends that, in hospitalized adults who smoke cigarettes, clinicians initiate varenicline during hospitalization to promote smoking cessation following discharge. Varenicline, a partial agonist at the nicotinic acetylcholine receptor, works by reducing both the reward associated with smoking and the withdrawal symptoms that drive relapse. It has consistently ranked among the most effective single-agent pharmacotherapies for cessation in randomized trials, and starting it in the hospital, rather than waiting for an outpatient visit that may never happen, ensures that patients leave with active treatment already underway.

The guideline also addresses the intensity and continuity of counseling, an area where inpatient practice varies enormously. For hospitalized adults who currently smoke cigarettes, the panel recommends inpatient tobacco treatment counseling lasting fifteen or more minutes over brief advice of less than fifteen minutes. The distinction matters because brief advice, while better than nothing, has modest effect sizes, whereas more substantial counseling sessions allow clinicians to assess dependence, discuss triggers, set quit plans, and address ambivalence using established behavioral techniques such as motivational interviewing. Requiring a minimum duration pushes institutions to allocate real staff time, whether through trained nurses, pharmacists, respiratory therapists, or dedicated cessation counselors, rather than treating a sentence about quitting as sufficient intervention.

Continuity of care forms the third highlighted pillar. The guideline recommends that inpatient counseling for hospitalized adults who smoke include a referral to postdischarge tobacco treatment counseling, with examples including scheduled follow-up contact and direct or electronic health record referral to a quitline or an outpatient program. The postdischarge period is where many inpatient cessation efforts collapse. Withdrawal symptoms intensify as patients return to environments saturated with smoking cues, and without structured follow-up, the momentum built during admission dissipates quickly. Quitlines, which provide free telephone-based coaching and in many jurisdictions medication support, offer a scalable bridge, and electronic health record-based referral systems can automate the connection, reducing the burden on bedside clinicians.

The logic of linking cessation to readmission reduction deserves emphasis. Patients admitted with exacerbations of COPD, acute coronary syndromes, pneumonia, or heart failure who continue smoking face elevated risks of returning to the hospital, and smoking cessation after such diagnoses measurably improves survival and reduces recurrent events. By embedding cessation into the inpatient workflow, hospitals can address a modifiable risk factor at the moment of maximal patient receptivity. The guideline’s authors argue that a standardized approach, applied to every hospitalized patient who smokes unless the patient explicitly declines, transforms cessation from an optional add-on into a default standard of care, analogous to venous thromboembolism prophylaxis or medication reconciliation.

The full set of six recommendations, including those not highlighted in the release, is available through the CHEST journal website in the article titled Tobacco Treatment in the Inpatient Setting: An American College of Chest Physicians Clinical Practice Guideline. As with other CHEST clinical practice guidelines, the recommendations synthesize the available literature using structured methodology, grading both the quality of evidence and the strength of each recommendation so that clinicians can understand how firmly each statement is supported. Guideline panels of this kind typically weigh randomized trial data, observational evidence, and patient values and preferences, and the published document details the rationale behind each recommendation for readers who need to adapt the guidance to local resources and populations.

For hospitals and health systems, the practical implications are significant. Implementing the guideline will require mechanisms to identify every admitted patient who smokes, typically through admission screening embedded in the electronic health record; protocols to prescribe varenicline where clinically appropriate, with attention to contraindications and drug interactions; staffing or consult services capable of delivering counseling sessions of at least fifteen minutes; and referral pathways that reliably connect patients to quitlines or outpatient programs before discharge. None of these components is technically difficult, but each requires institutional commitment, and the guideline’s standardization is intended to make that commitment easier to justify and audit. For the roughly one in eight American adults who smoke, many of whom will pass through a hospital bed in any given year, the guideline converts a fleeting admission into a structured pathway toward quitting, one that begins at the bedside and continues long after discharge.
