Sustainability of an Opt-Out Electronic-Health Record-Based Tobacco Treatment Consult Service at a Large Safety-Net Hospital: A 6-Year Analysis

Introduction: Our safety-net hospital implemented a hospital-based tobacco treatment intervention in 2016. We previously showed the intervention, an "opt-out" Electronic Health Record (EHR)-based Best Practice Alert (BPA)+ order-set that triggers consultation to an inpatient Tobacco Treatment Consult (TTC) service for all patients who smoke, improves smoking abstinence. We now report on sustainability, 6 years after inception.

Aims and methods: We analyzed data collected between July 2016-June 2022 of patients documented as "currently smoking" in the EHR. Across the 6 years, we used Pearson's correlation analysis to compare Adoption (clinician acceptance of the BPA+ order-set, thus generating consultation to the TTC service); Reach (number of consultations completed by the TTC service); and Effectiveness (receipt of pharmacotherapy orders between patients receiving and not receiving consultations).

Results: Among 39 558 adult admissions (July 2016-June 2022) with "currently smoking" status in the EHR for whom the BPA triggered, clinicians accepted the TTC order set on 50.4% (19 932/39 558), though acceptance varied across services (eg, Cardiology [71%] and Obstetrics-Gynecology 12%]). The TTC service consulted on 17% (6779/39 558) of patients due to staffing constraints. Consultations ordered (r = -0.28, p = .59) and completed (r = 0.45, p = .37) remained stable over 6-years. Compared to patients not receiving consultations, patients receiving consultations were more likely to receive pharmacotherapy orders overall (inpatient: 50.8% vs. 35.1%, p < .0001; at discharge: 27.1% vs. 10%, p < .0001) and in each year.

Conclusions: The "opt-out" EHR-based TTC service is sustainable, though many did not receive consultations due to resource constraints. Health care systems should elevate the priority of hospital-based tobacco treatment programs to increase reach to underserved populations.

Implications: Our study shows that opt-out approaches that utilize the EHR are a sustainable approach to providing evidence-based tobacco treatment to all hospitalized individuals who smoke, regardless of readiness to stop smoking and clinical condition.
