Application of HARM Score to Measure Surgical Quality and Outcomes in Bariatric Patients

BACKGROUND: The HospitAl stay, Readmission, and Mortality rates (HARM) score is a quality indicator that is easily determined from routine administrative data. However, the HARM score has not yet been applied to patients undergoing bariatric surgery. OBJECTIVE: The aims of the present study were 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. METHODS: A MBSAQIP 2015 PUF database was reviewed. For each discharge, a 1 to 10 score was calculated on the basis of length of stay (LOS), discharge status, and 30-day readmissions. We adjusted the LOS categories to the distribution of LOS in the MBSQIP database. The new LOS categories were used to calculate the modified HARM score, referred to as the BARiatric HARM (BAR-HARM) score. The association between HARM and BAR-HARM scores and complication rate was assessed. RESULTS: A total of 197,141 cases were evaluated: 98.8% were elective and 1.2% were emergent admissions. The mean individual patient BAR-HARM score was 1.75 ± 1.04 for elective cases, and 2.02 ± 1.45 for emergency cases. The complication rates for the respective BAR-HARM categories ≤ 2, > 2 to 3, > 3 to 4, and > 4 were 3.95, 27.53, 40.14, and 79.97% (p < 0.001). CONCLUSIONS: The quality of bariatric surgery can be reliably and validly assessed using the BAR-HARM score, which is a modification of the HARM score.
