BACKGROUND: Although electronic product identification in the consumer sector is ubiquitous, unique identification of medical devices is just being implemented in 2014. To evaluate unique device identifiers (UDIs) in health care, the US Food and Drug Administration (FDA) funded the Medical Device Epidemiology Network initiative, including a demonstration of the implementation of coronary stent UDI data in the information systems of a multihospital system (Mercy Health). This report describes the first phase of the demonstration.

METHODS: An expert panel of interventional cardiologists nominated by the American College of Cardiology and the Society for Cardiovascular Angiography and Interventions was convened with representatives of industry, health system members of the Healthcare Transformation Group, the American College of Cardiology National Cardiovascular Data Registry, and FDA to articulate concepts needed to best use UDI-associated data. The expert panel identified 3: (1) use cases for UDI-associated data (eg, research), (2) a supplemental data set of clinically relevant attributes (eg, stent dimensions), and (3) governance and administrative principles for the authoritative management of these data.

RESULTS: Eighteen use cases were identified, encompassing clinical care, supply chain management, consumer information, research, regulatory, and surveillance domains. In addition to the attributes of the FDA Global Unique Device Identification Database, 9 additional coronary stent-specific attributes were required to address use case requirements. Recommendations regarding governance were elucidated as foundational principles for UDI-associated data management.

CONCLUSIONS: This process for identifying requisite extensions to support the effective use of UDI-associated data should be generalizable. Implementation of a UDI system for medical devices must anticipate both global and device-specific information.

Objective: To assess national trends of iatrogenic complications and associated burden of care among patients undergoing open and minimally invasive prostatectomy using a population-based cohort. Methods: Using the nationally representative cohort, we identified patients who were diagnosed with prostate cancer, and underwent prostatectomy during 2001 and 2011. We determined the risk of iatrogenic complication and length of stay (LOS) over time among open and minimally invasive surgery (MIS) patients. Hierarchical multivariable logistic regression was performed to assess the changes over time and elucidate independent predictors of iatrogenic complications. Results: We identified 556,932 and 219,434 prostate cancer patients undergoing open and minimally invasive prostatectomy. We found that iatrogenic complications for MIS were less frequent in later years (years 09-11 vs. year 01-02 odds ratio (OR), 0.21; 95% confidence intervals (CI), 0.09-0.40). MIS was associated with higher risk of iatrogenic complications in early period (years 01-02 OR, 3.81; 95% CI, 1.72-8.41), but lower risk in late period (years 09-11 OR 0.72 95% CI 0.61-0.86). Patients who experienced iatrogenic complications tended to have longer LOS (Median: Open vs. MIS, 4 days vs. 3 day) than those who didn’t (Median: Open vs. MIS, 2 days vs. 1 day), regardless of procedure type. Conclusion: We found that minimally invasive prostatectomy is associated with lower risk of iatrogenic complications when compared with open surgery (OS). However, as “learning curve” is overcome over time, MIS becomes safer than OS. Iatrogenic complications are not benign and seem to be associated with higher burden of inpatient care.

IN RECENT YEARS, HIGH-PROFILE CASES OF MEDICAL device failure resulting in patient harm—such as implantable cardioverter-defibrillator leads and metal-on metal hip implants—have received substantial attention both in the medical literature and popular press. These examples illustrate the need for a more effective system of monitoring device performance and protecting patient safety. The first action in the Food and Drug Administration’s (FDA’s) report on strengthening postmarket device surveillance, “establish a Unique Device Identification (UDI) System and promote its incorporation into electronic health information,” was addressed with publication of the UDI Proposed Rule.

This viewpoint article by Natalia Wilson and Joseph Drozda, published prior to publication of the Final Rule, highlights the role of UDI in supporting an effective medical device monitoring system and enhanced patient safety. The authors lay out the expected benefits of a UDI system to strengthen post market surveillance of medical devices, ensure ability to track a device across health care settings, support safe and accurate device use, standardize device documentation in health information technology (HIT) systems, enhance recall management, and support health care cost savings.

The FDA’s plan is a big ask but will be well worth the effort

In September 2012, the US Food and Drug Administration (FDA) released its vision for a postmarket surveillance system for medical devices, describing four key strategies to protect public health. But why this initiative now? Firstly, several concerns about the safety of specific devices, such as the Medtronic Fidelis defibrillator lead and the DePuy ASR hip implant, have garnered substantial press coverage. Secondly, the Institute of Medicine recently called for a substantial overhaul of processes for the approval and postmarket safety surveillance of medical devices. Thirdly, the FDA has undertaken several premarket initiatives to improve the efficiency of the regulatory review for innovative devices. With the number and complexity of medical devices growing rapidly, it is timely to complement the new premarket initiatives with a strong postmarket surveillance program.

Regulation of the entry into use of medical devices in the United States was introduced after that for drugs table, and it quickly became apparent that the public health assessment of devices would need to be different from that of drugs. Unlike drugs, medical devices are assembled from many components, may affect patients long after the initial exposure, and have rapid product development cycles, which lead to frequent incremental improvements. Medical devices also pose unique challenges to studying …
