general practice referral of at risk populations to community leisure services applying the reaim framework to evaluate the impact of a communitybased physical activity programme for inactive adults with longterm conditions background in the uk a high proportion of adults with longterm conditions do not engage in regular physical activity general practice gp referral to communitybased physical activity is one strategy that has gained traction in recent years however evidence for the realworld effectiveness and translation of such programmes is limited this study aimed to evaluate the individual and organisational impacts of the click into activity programme gp referral of inactive adults living with or at risk of longterm conditions to communitybased physical activitymethods a mixed methods evaluation using the reaim framework was conducted with data obtained from a range of sources followup questionnaires qualitative interviews and programmerelated documentation including programme cost data triangulation methods were used to analyse data with findings synthesised across each dimension of the reaim frameworkresults a total of 602 individuals were referred to click into activity physical activity sessions of those referred 326 individuals participated in at least one session the programme therefore reached 302 of the 1080 recruitment target a range of individual social and environmentallevel factors contributed to initial physical activity participation positive changes over time in physical activity and other outcomes assessed were observed among participants programme adoption at gp surgeries was successful but the gp referral process was not consistently implemented across sites physical activity sessions were successfully implemented with programme deliverers and groupbased delivery identified as having an influential effect on programme outcomes changes to physical activity session content were made in response to participant feedback click into activity cost 175000 over 3 years with an average cost per person attending at least one programme session of 535conclusions despite not reaching its recruitment target click into activity was successfully adopted positive outcomes were associated with participation although low 6 and 12month followup response rates limit understanding of longerterm programme effects contextual and individual factors which may facilitate successful implementation with the target population were identified findings highlight strategies to be explored in future development and implementation of gp referral to communitybased physical activity programmes targeting inactive adults living with or at risk of longterm conditions
