Mortality-weighted severe maternal morbidity: a novel approach to assessing maternal health outcomes
The mortality-weighted w-SMM index improves upon the binary SMM composite measure by accounting for the varying severity of individual and combined SMM indicators and can further serve as a more granular measure of in-hospital mortality risk. The w-SMM index can be used retrospectively to stratify high-risk patients, enhance risk adjustment models, and support comparative outcomes research that informs public health policy development, future research, policy decisions, and clinical practice.
