Scientific title
Primary care Osteoarthritis Screening Trial (POST): a cluster randomised trial of an electronic prompt for comorbidity screening in clinical osteoarthritis consultations in primary care
Acronym
POST
Study hypothesis
POST is a cluster randomised clinical trial that will compare pain intensity and interference outcomes over a 12-month period in osteoarthritis (OA)/joint pain patients screened for depression and anxiety (intervention arm) to those who receive usual care (control arm; screened only for pain intensity).
As a cluster randomised trial the GP practices will be randomised (to one of the 2 arms) rather than the patients. We aim to recruit 44 GP practices in total in order to screen and contact 1745 patients. Recruitment of patients from GP practices will take place over 12 months. It is anticipated that patients will be contacted within 1-2 weeks of their index consultation with a baseline questionnaire and those who consent will be followed-up with further postal questionnaires 3, 6 and 12 months following their baseline. These questionnaires contain detailed questions on pain intensity and interference (our primary outcomes) and further questions on anxiety, depression, pain catastrophising, health economics and demographics. A medical record review of treatments, diagnoses and referrals will be conducted for patients who consent
