Development of a Pragmatic Measure for Evaluating and Optimizing Rapid Response Systems
Bonafide CP et al. – The critical deterioration rate is a valid, pragmatic proximate outcome associated with in–hospital mortality. It has great potential for complementing existing patient safety measures for evaluating rapid response systems (RRSs) performance.
The authors reviewed 724 medical emergency team and 56 code-blue team activations in a children’s hospital between February 2010 and February 2011.
By using in-hospital mortality as the gold standard, they evaluated the test characteristics and validity of this proximate outcome metric compared with a national benchmark for cardiac and respiratory arrest rates, the Child Health Corporation of America Codes Outside the ICU Whole System Measure.
Critical deterioration (1.52 per 1000 non-ICU patient-days) was more than eightfold more common than the Child Health Corporation of America measure of cardiac and respiratory arrests (0.18 per 1000 non-ICU patient-days) and was associated with >13-fold increased risk of in-hospital death.
The critical deterioration metric demonstrated both criterion and construct validity.
