The usefulness of a 28-item Therapeutic Intervention Scoring System (TISS-28) in critically ill obstetric patients to detect multiorgan dysfunction: A prospective cohort study.

Background: This study evaluated the effectiveness of the 28-item Therapeutic Intervention Scoring System (TISS-28) in detecting multiorgan dysfunction (MOD) among critically ill obstetric patients and compared its predictive potential to other severity models, such as Sequential Organ Failure Assessment (SOFA) and Mortality Probability Model II (MPM II).

Methods: A prospective multicentre cohort study was conducted including obstetric patients, pregnant and up to 42 days postpartum, admitted to the intensive care units of two referral hospitals in Colombia. A total of 93 patients were recruited between March 2016 and February 2017 and from September 2019 to November 2019.
