Core Outcome Measures in Effectiveness Trials

The patient perspective of living with surgery for morbid obesity: Creating a patient 'core' outcome set, and investigating ways to improve follow-up care.

General Information

Abstract:
Obesity is an increasing health problem worldwide. Surgical treatment can lead to dramatic weight loss and improvement of weight-related illnesses, but also has associated risks. Current standard evaluation focuses on surgical complications that are important to clinicians, however, little is known about how surgery affects outcomes that are important to patients. This project will use mixed methodology to establish outcomes that patients consider to be important after obesity surgery and how post-operative support can be improved. This will will help researchers ensure outcomes important to patients are measured and help improve NHS services for obesity surgery based on patient needs.

Systematic review

Systematic reviews of published quantitative and qualitative research will be undertaken to create a long list of outcomes that may be important to obesity surgery patients. This will be supplemented with qualitative interviews with obesity surgery patients to see if published outcomes reflect the outcomes that patients themselves consider to be important. The interviews will also establish how post-operative support in the NHS can be improved. Delphi questionnaire rounds followed by consensus meetings with obesity surgery patients will be undertaken to reduce the long list of outcomes to the most important ‘core’ outcomes to create a patient core outcome set for obesity surgery.
