Behaviourally informed, patient-led interventions to reduce missed appointments in general practice: a 12-month implementation study.

Background: Scalable, positive, behaviourally informed interventions may help people remember to attend their primary care appointment or cancel in good time, but have not yet been implemented long term.

Aim: To examine effects of social norms and making active commitments on missed and cancelled appointments in primary care over 12 months and explore implementation factors.

Design And Setting: A mixed-methods design evaluation and implementation study led by a Patient Participation Group (PPG) member in a large GP practice in the West Midlands.
