Can a patient decision aid reduce people's intentions to have shoulder surgery

A patient decision aid outlining the options of having surgery for shoulder pain (subacromial decompression surgery or rotator cuff repair surgery) and not having surgery, and the benefits and harms of each, with the options (non-surgical options vs. surgery) displayed in two formats: - side-by-side - top-and-bottom The two patient decision aid formats will be delivered as two separate intervention arms (i.e. participants will be randomly allocated to view only one format). The patient decision aid was co-developed with patients and health professionals specifically for this trial (i.e. it is not publicly available yet) and incorporates the best available evidence on subacromial decompression surgery and rotator cuff repair surgery from the most recent Cochrane reviews of these surgeries. Information in the decision aid is presented under the following headings: • Who should read this decision aid? • What are the treatment options covered in this decision aid? • What are the likely benefits of surgery compared to non-surgical options? • What are the likely complications of surgery? • Summary of benefits, harms, and other practical issues • Questions to consider when talking with a health professional Participants in the intervention group will view the patient decision aid online for a minimum of 3 minutes before being directed to complete questionnaires assessing knowledge, attitudes, treatment intentions and decisional conflict. The patient decision aid will be displayed for a minimum of 3 minutes to ensure participants do not skip reading the patient decision aid.
