Risk factors for initial appointment non-attendance at Improving Access to Psychological Therapy (IAPT) services: A retrospective analysis.

Background: Approximately 1.5 million referrals are made to Improving Access to Psychological Therapy (IAPT) services annually. However, treatment is received in less than half of cases due to ineligibility or non-attendance. The aim was to explore risk factors for non-attendance at the initial two IAPT appointments following referral.
Methods: An exploratory, retrospective analysis of referral and attendance data from five IAPT services in the North of England. Participants were 97,020 referrals received 2010-2014. Main outcome was attendance at the first two offered appointments (assessment and initial treatment).
Results: Based on data from two services, 66% of referrals resulted in assessment attendance. Across all five services 57% of patients who attended for assessment subsequently attended the first treatment appointment. The odds of attending an assessment appointment were more than 3 times higher for self-referrals than for GP referrals (OR 3.46, 95% CI 3.27-3.66, p  < 0.001). Factors important to treatment appointment attendance following assessment were the service, referral source, presenting problem, and anxiety severity.
Conclusion: Initial appointment non-attendance is a consistent problem for IAPT services. Specific factors that may support IAPT services to improve non-attendance rates are identified. IAPT indicators of success should take account of non-attendance at initial appointments.
