Data collection systems for weight loss surgery: an evidence-based assessment

To evaluate the existence and efficacy of data collection systems for weight loss surgery (WLS) and establish evidence-based guidelines for the development of a statewide WLS registry in Massachusetts.

We conducted two systematic searches of English language literature in MEDLINE. The first was on data collection registries related to WLS; the second was an expanded search encompassing other surgical fields (e.g., cardiac and thoracic surgery) and registries (i.e., cancer). Fourteen articles were found to be pertinent. Data were extracted, and evidence categories were assigned according to a grading system based on established evidence-based models. Recommendations were derived from these literature reviews and expert opinion.

This task group found that there are no standardized data collection systems for WLS in Massachusetts (or any other states) and no mandated reporting of WLS-specific outcomes. We described existing WLS databases and systems in other surgical fields. Recommendations focused on the importance and feasibility of data collection for WLS and the need to conduct a pilot study and explore options for creating a statewide WLS database.

A statewide WLS data collection system would optimize patient care by enabling the collection, analysis, and dissemination of best practice data. A broad-based effort is needed to meet challenges involved in defining and implementing such a system.
