Trattamento personalizzato del tabacco nelle cure primarie

2 novembre 2026 aggiornato da: Washington University School of Medicine

Un intervento multilivello per personalizzare e migliorare il trattamento del tabacco nelle cure primarie

This study examines the application of precision treatment intervention for smoking cessation from both the clinician perspective and patient perspective, and compares it to usual care on tobacco treatment in the primary care setting. The precision treatment intervention includes personalized tobacco treatment recommendations using the patient's clinical, genetic, and biomarker information. This approach may increase effectiveness and adherence for the patient, and increase the clinician's likelihood of prescribing.

Panoramica dello studio

Descrizione dettagliata

The overarching goal of this study is to test the impact of a multilevel precision treatment intervention aiming to address gaps in clinician and patient uptake of tobacco treatment and overall treatment effectiveness. This study builds on evidence that (1) genetic and metabolic factors may inform precision tobacco treatment and (2) increasingly high demand for precision treatment, in particular, may signal its potential to activate behavior change. The multilevel precision treatment intervention to be tested--PrecisionTx-- provides the opportunity to present personalized risk, benefit, and treatment recommendation to increase clinician ordering, patient uptake, and overall effectiveness of tobacco treatment. This study aims to understand the relative benefit of precision treatment over usual care and associated mechanistic and implementation outcomes. Therefore, the investigators propose a 2-arm cluster randomized controlled trial of 50 clinicians and 800 screen-eligible patients (~16 per clinician) from diverse primary care settings. Clinicians and patients will be randomized with 1:1 allocation to usual care (UC) vs. precision treatment (PT) to evaluate the effect of precision treatment on smoking cessation success. In Aim 1, the investigators will test the effect of PT on clinician prescribing (or patient receipt of medication when prescription is not needed) and patient use of medication for smoking cessation. The investigators hypothesize that patient receipt of tobacco treatment medication for smoking cessation at 6 months post-intervention will be higher in PT vs UC. The investigators also hypothesize that patient use of cessation medication at 6 months post-intervention will be higher in PT vs. UC. In Aim 2, the investigators will test the effect of PT on patient smoking abstinence. The investigators hypothesize that patient bioverified smoking abstinence at 6 months will be higher in PT vs. UC. In Aim 3, the investigators will examine mechanisms of behavior change and implementation outcomes. The investigators will evaluate putative mechanisms for PT (e.g., outcome expectancy and withdrawal suppression). The investigators will conduct assessments at baseline, intervention, and 1-month, 3-month, 6-month, and 12-month post-intervention follow-ups.

Primary outcomes include patient receipt of tobacco treatment, patient use of tobacco treatment, and patient smoking abstinence. Secondary outcomes include patient receipt of recommended medication, patient medication adherence, and additional patient smoking cessation outcomes. Mechanistic outcomes include clinician level (perceived benefit, outcome expectancy), clinician-patient interaction (self-efficacy), patient-level (perceived risk, outcome expectancy, withdrawal suppression, adverse events). Implementation outcomes will be evaluated based on the RE-AIM framework. The study is an innovative paradigm shift from a traditional treatment model to precision treatment that includes both metabolic and genetic markers to motivate and guide tobacco treatment for both clinicians and patients, integrated within primary care.

Smoking is a leading cause of premature death, causing more than half of all cancer deaths. However, tobacco treatment is often not provided and is not highly effective in primary care. New evidence suggests that a precision treatment approach to motivate and guide treatment based on personal genetic and metabolic markers could improve treatment uptake and quit success. This study will test the impact of a multilevel precision treatment intervention on improving tobacco treatment and health outcomes in primary care.
