ABSTRACT
OBJECTIVES:
To evaluate the effectiveness of a complex intervention to improve referral and treatment of pregnant smokers in routine practice, and to assess the incremental costs to the National Health Service (NHS) per additional woman quitting smoking.DESIGN:
Interrupted time series analysis of routine data before and after introducing the intervention, within-study economic evaluation.SETTING:
Eight acute NHS hospital trusts and 12 local authority areas in North East England.PARTICIPANTS:
37 726 records of singleton delivery including 10 594 to mothers classified as smoking during pregnancy.INTERVENTIONS:
A package of measures implemented in trusts and smoking cessation services, aimed at increasing the proportion of pregnant smokers quitting during pregnancy, comprising skills training for healthcare and smoking cessation staff; universal carbon monoxide monitoring with routine opt-out referral for smoking cessation support; provision of carbon monoxide monitors and supporting materials; and an explicit referral pathway and follow-up protocol. MAIN OUTCOMEMEASURES:
Referrals to smoking cessation services; probability of quitting smoking during pregnancy; additional costs to health services; incremental cost per additional woman quitting.RESULTS:
After introduction of the intervention, the referral rate increased more than twofold (incidence rate ratio=2.47, 95% CI 2.16 to 2.81) and the probability of quitting by delivery increased (adjusted OR=1.81, 95% CI 1.54 to 2.12). The additional cost per delivery was £31 and the incremental cost per additional quit was £952; 31 pregnant women needed to be treated for each additional quitter.CONCLUSIONS:
The implementation of a system-wide complex healthcare intervention was associated with significant increase in rates of quitting by delivery.Palavras-chave
