Quantifying the utilization of medical devices necessary to detect postmarket safety differences: a case study of implantable cardioverter defibrillators.
The purpose of this study was to estimate medical device utilization needed to detect safety differences among implantable cardioverter defibrillators (ICDs) generator models and compare these estimates to utilization in practice. The investigators concluded that small safety differences among ICD generator models are unlikely to be detected through routine surveillance given current ICD utilization in practice, but large safety differences can be detected for most patients at anticipated average adverse event rates.

National landscape of unplanned 30-day readmissions in patients with left ventricular assist device implantation.
This study tracked unplanned 30-day readmissions in patients who had undergone left ventricular assist device (LVAD) implantation during 2013. Data from the Healthcare Cost and Utilization Project (HCUP) National Readmission Database was used. Out of 2,235 patients who had an LVAD implantation, 29.7% had at least 1 unplanned readmission within 30 days. The top reasons for readmission were implant complications (14.9%), congestive heart failure (11.7%), and gastrointestinal bleeding (8.4%). Predictors of readmission included a prolonged length stay during the primary admission, Medicare insurance, and discharge to a short-term facility.

Association of cardiac rehabilitation with decreased hospitalizations and mortality after ventricular assist device implantation.
This study examined whether outcomes of cardiac patients who had received ventricular assist device (VAD) implementation had decreased hospitalization and mortality with cardiac rehabilitation (CR). Medicare beneficiaries enrolled for disability or aged 65 years and older in 2014 were included. The investigators identified VAD recipients by diagnosis codes. It was found that each 5-year increase in age was associated with attending an additional 1.6 CR sessions and there was a 23% lower 1-year hospitalization risk and a 47% lower 1-year mortality risk.
