Janik MR, et al. - Given that the HospitAl stay, Readmission, and Mortality rates (HARM) score is a quality indicator that is easily determined from routine administrative data, researchers sought to adjust the HARM score to the bariatric population and to validate the ability of the modified HARM score to serve as an inexpensive tool to measure the quality of bariatric surgery. They used the new LOS categories to calculate the modified HARM score, referred to as the BARiatric HARM (BAR-HARM) score. In this work, the BAR-HARM score appeared as a reliable and valid tool for assessing the quality of bariatric surgery.
