Comorbidity data collection across different spine registries: an evidence map.

Area of Science:

• Medical Informatics
• Epidemiology
• Spine Surgery Outcomes

Background:

• Comorbidities significantly impact surgical outcomes.
• Current collection of comorbidity data in spine surgery literature is highly inconsistent.
• The Australian Spine Registry aimed to address this variability.

Purpose of the Study:

• To map the current landscape of comorbidity data collection in spine registries.
• To identify what comorbidities are collected, how they are collected, and the completeness of this data.
• To provide guidance for systematic data collection in spine registries.

Main Methods:

• Conducted a literature search of adult spine registry studies reporting comorbidities.
• Sent targeted questionnaires to global spine registries.
• Built an evidence map based on literature review and registry responses.

Main Results:

• Thirty-six studies met inclusion criteria; significant variation in comorbidity reporting was found.
• Only 55% of studies reported comorbidity collection, 25% detailed collection methods, and 20% used a comorbidity index.
• Responses from 7 registries confirmed varied methods and use of recognized comorbidity indices by only 3.

Conclusions:

• The evidence map revealed substantial heterogeneity in comorbidity data collection methodologies and reporting across spine registries.
• A standardized approach to comorbidity data collection is needed.
• Standardization will facilitate collaboration, data comparison, and predictive modeling for improved patient outcomes in spine surgery.
