How effective are electronic health record (EHR)-facilitated interventions at increasing smoking cessation support actions by clinicians, and when it comes to patient cessation outcomes?
As few randomised studies existed, it was not possible to conduct a meta-analysis. Eight of the 11 studies were nonrandomised observational studies, and 5 of these lacked a control group. Small sample sizes and convenience sampling of included clinics increased the potential risk of selection bias. None of the studies included a direct assessment of patient quit rates.
Health information systems, such as EHRs, computerised decision-support systems and electronic prescribing, are potentially valuable components for improving the quality and efficiency of clinical interventions for tobacco use.
