Abstract 18052: Does Therapeutic Hypothermia Influence Hospital Length of Stay in Cardiac Arrest Survivors
Introduction Therapeutic Hypothermia (TH) is standard of care in improving neurological outcomes in cardiac arrest survivors. Whether the use of TH influences the hospital length of stay (LOS) in these patients is of interest since LOS is a major driver of medical care costs. We investigated the influence of TH on hospital LOS in cardiac arrest survivors.
Methods A retrospective analysis was performed on 263 consecutive cardiac arrest patients admitted to a tertiary medical center from December 2003 to June 2012. Patients were categorized into two groups: patients who did not undergo TH (controls) and those that underwent TH (hypothermia). The LOS was defined as time period from date of cardiac arrest to the date of discharge from the hospital. Data was collected on age, gender, history of CHF, type of presenting rhythm, time to return to spontaneous circulation (ROSC), serum creatinine, pH and ejection fraction (EF) on admission. Patients who did not survive till hospital discharge (n=166) were excluded from the analysis.
Results The mean hospital LOS for hypothermia patients was 11.78 ± 9.75 days as compared to 8.74 ± 7.36 days in the control group (P=0.398). On multivariable analysis using multiple linear regression, EF on admission( 95 % CI 0.037-0.230, P=0.008) and time to ROSC( 95 % CI -0.49-0.16, P=0.004) were independent predictors of hospital LOS.
Conclusion The use of TH does not influence hospital LOS in cardiac arrest survivors. However, EF on admission and time to ROSC are predictive of hospital LOS in cardiac arrest survivors.
