OBJECTIVES: NHS Stop Smoking Services provide various options for support and counselling. Most services have evolved to suit local needs without any retrospective evaluation of their efficiency. Objective was to describe the structure and outcomes associated with different services METHODS: Local service evaluations were done in three primary Care Trusts (PCTs) by conducting standardised interviews with key personnel in addition to extraction and analysis of data from 400 clients accessing the service after 1st April 2008 in each PCT RESULTS: The PCTs varied in geography, population size and quit rate (47%-63%). Services were delivered by PCT-led specialist teams (PCT1), community-based health care providers (PCT3) and a combination of the two (PCT2) with varying resources and interventions in each. Group support resulted in the highest quit rates (64.3% for closed groups v 42.6% for one-to-one support (PCT1)). Quit rates were higher for PCT (75%) versus GP (60%) and pharmacist-delivered care (40%) where all existed in the same model (PCT2). The most-prescribed therapy was NRT (56%-65%), followed by varenicline (25%-34%), counselling alone (6%-8%) and bupropion (2%-4%). Quit rates for NRT at 4 weeks were 43%-55% across the 3 PCTs; 60% -81% for varenicline and 38%-91% for bupropion CONCLUSIONS: The results suggest that service structure, method of support, healthcare professional involved and pharmacotherapy all play a role in a successful quit. Services must be tailored to support individual needs with patient choice and access to varied services being key factors.
