HOSPITAL READMISSIONS IN PATIENTS SUPPORTED WITH DURABLE CENTRIFUGAL-FLOW LEFT VENTRICULAR ASSIST DEVICES. JOURNAL OF CLINICAL MEDICINE, 13(10), 2869. HTTPS://DOI.ORG/10.3390/JCM13102869. MANUFACTURER'S INVESTIGATION CONCLUSION: A DIRECT CORRELATION BETWEEN HEARTMATE 3 LEFT VENTRICULAR ASSIST SYSTEMS (LVAS) AND THE REPORTED EVENTS COULD NOT CONCLUSIVELY BE ESTABLISHED THROUGH THIS EVALUATION. CENTRIFUGAL-FLOW LEFT VENTRICULAR ASSIST DEVICES (CF-LVADS) HAVE IMPROVED MORBIDITY AND MORTALITY FOR LVAD RECIPIENTS. HOSPITAL READMISSIONS, HOWEVER, REMAIN COMMON AND AFFECT QUALITY OF LIFE AND SURVIVAL. WE SOUGHT TO IDENTIFY FACTORS ASSOCIATED WITH READMISSIONS ON LVAD SUPPORT. HOSPITAL READMISSIONS FOLLOWING LVAD IMPLANTATION REMAIN A COMMON AND VEXING CLINICAL ISSUE ADVERSELY AFFECTING PATIENT QUALITY OF LIFE AND SURVIVAL, AS WELL AS INCREASING HEALTHCARE COSTS AND RESOURCE UTILIZATION [1¿4]. IT HAS BEEN REPORTED THAT UP TO 71% OF PATIENTS ARE REHOSPITALIZED WITHIN ONE YEAR FOLLOWING LVAD IMPLANTATION. DATA WERE COLLECTED TWO TO FOUR MONTHS FOLLOWING LVAD IMPLANTATION, WITH AT LEAST TWO CONSECUTIVE WEEKS BEING REQUIRED AS A MINIMUM FOR A PATIENT TO BE CONSIDERED AS BEING ON A SPECIFIC PHARMACOLOGIC AGENT THERAPY. PATIENTS RECEIVING A CF-LVAD BETWEEN FEBRUARY 2011 AND MARCH 2021 WERE PROSPECTIVELY EVALUATED. HOSPITAL READMISSIONS WERE DICHOTOMIZED INTO HF/LVAD-RELATED OR NON-HF/LVAD-RELATED. MULTIVARIABLE LOGISTIC REGRESSION MODELS AUGMENTED USING THE LEAST ABSOLUTE SHRINKAGE AND SELECTION OPERATOR METHOD FOR VARIABLE SELECTION WERE USED TO ESTIMATE ASSOCIATIONS BETWEEN =1 HF/LVAD-RELATED READMISSIONS AND CLINICAL VARIABLES. THE PRIMARY OUTCOME OF INTEREST WAS THE INCIDENCE OF ANY HF/LVAD-RELATED READMISSION UP TO THREE YEARS POST-LVAD IMPLANTATION HOSPITAL DISCHARGE. THE SECONDARY OUTCOME WAS THE HAZARD OF HF/LVAD-RELATED READMISSIONS WHILE ON LVAD SUPPORT OVER THE THREE YEARS POST-LVAD IMPLANTATION HOSPITAL DISCHARGE. A MODEL WAS CREATED ACCURATELY IDENTIFYING PATIENTS WITH A HIGH LIKELIHOOD OF READMISSIONS AFTER LVAD IMPLANT. MOST VARIABLES ASSOCIATED WITH READMISSION CAN BE IDENTIFIED PRE-OPERATIVELY. THE FINDINGS CAN GUIDE THE IMPLEMENTATION OF THERAPEUTIC STRATEGIES TO MITIGATE READMISSION RISK AND FURTHER IMPROVE OUTCOMES. THE HEARTMATE 3 LVAS INSTRUCTIONS FOR USE (IFU) LISTS THE ADVERSE EVENTS, INCLUDING DEVICE MALFUNCTIONS, THAT MAY BE ASSOCIATED WITH THE USE OF HEARTMATE 3 LVAS. THE HEARTMATE 3 LVAS PATIENT HANDBOOK ALSO LISTS EXAMPLES OF EMERGENCIES, AND THE RECOMMENDED ACTIONS ASSOCIATED WITH THESE EMERGENCIES. FURTHERMORE, THE PATIENT HANDBOOK INSTRUCTS THE USER TO CALL THEIR HOSPITAL CONTACTS IF THEY THINK, FOR ANY REASON, ANY PORTION OF THEIR EQUIPMENT IS NOT FUNCTIONING AS USUAL, IS BROKEN, OR THEY ARE UNCOMFORTABLE WITH THE OPERATION OF THE EQUIPMENT. THE HEARTMATE 3 LEFT VENTRICULAR ASSIST SYSTEM (LVAS) INSTRUCTIONS FOR USE (IFU) AND THE HEARTMATE 3 PATIENT HANDBOOK ARE CURRENTLY AVAILABLE. SECTION 1 OF THE IFU, ¿INTRODUCTION¿, LISTS THE ADVERSE EVENTS, INCLUDING DEVICE MALFUNCTIONS, THAT MAY BE ASSOCIATED WITH THE USE OF THE HEARTMATE 3 LEFT VENTRICULAR ASSIST SYSTEM. SECTION 8 OF THE PATIENT HANDBOOK, ¿HANDLING EMERGENCIES¿, LISTS EXAMPLES OF EMERGENCIES AND THE RECOMMENDED ACTIONS ASSOCIATED WITH THESE EMERGENCIES. FURTHERMORE, THE PATIENT HANDBOOK INSTRUCTS THE USER TO CALL THEIR HOSPITAL CONTACTS IF THEY THINK, FOR ANY REASON, ANY PORTION OF THEIR EQUIPMENT IS NOT FUNCTIONING AS USUAL, IS BROKEN, OR THEY ARE UNCOMFORTABLE WITH THE OPERATION OF THE EQUIPMENT. NO FURTHER INFORMATION WAS PROVIDED. THE MANUFACTURER IS CLOSING THE FILE ON THIS EVENT.
