Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in patients older than age 55, with operative management being a widely adopted approach. Previous work has shown that private insurance status, gender and patient race are predictive of the operative approach patients receive (anterior-only, posterior-only, combined anterior-posterior). The Nationwide Inpatient Sample from 2001 to 2010 was used to assess the potential role of multilevel CSM as a contributing factor in determining which operative approach CSM patients receive, as it is rare for an anterior-only approach to be sufficient for CSM patients requiring fusion of four or more involved levels...

BACKGROUND: The incidence of breast cancer (BC) cases has increased significantly. The number of breast reconstruction (BR) procedures performed has mirrored this trend. Although implant-only procedures remain the most commonly used type of immediate BR, autologous techniques involving donor sites account for approximately 20%. The aim of this study was to assess national and regional trends in different types of autologous BR. METHODS: Using the Nationwide Inpatient Sample database (2008 to 2012), data on BC and mastectomy rates, type of autologous BR, and sociodemographics were obtained and analyzed...

BACKGROUND: Obesity is a well-established risk factor for total joint arthroplasty (TJA) and a number of complications including prosthetic joint infection. The annual changes in the prevalence of obesity among primary, revision, and infected TJA has not been studied at a national level. Given the higher costs of complications of TJA, it is important to understand the association of obesity with the annual trends of revision and infected TJA. QUESTIONS/PURPOSES: (1) Is the prevalence of obesity increasing among patients undergoing THA/TKA? (2) Is the prevalence of obesity increasing among patients undergoing revision THA/TKA? (3) Is the prevalence of obesity increasing among patients with infected THA/TKA? METHODS: Annual volumes of primary, revision, and infected THA and TKA from 1998 to 2011 were obtained from the Nationwide Inpatient Sample...

BACKGROUND: Despite extensive research regarding risk factors for adverse events after total joint arthroplasty (TJA), there are few publications describing the timing at which such adverse events occur. QUESTIONS/PURPOSES: (1) On which postoperative day do certain adverse events occur? (2) What adverse events occur earlier after TKA than after THA? (3) For each adverse event, what proportion occurred after hospital discharge? METHODS: We screened the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) to identify all patients undergoing primary THA and primary TKA between 2005 and 2013, resulting in a study population of 124,657 patients evaluated as part of this retrospective database analysis...

INTRODUCTION: Abdominal based breast reconstruction exists in a continuum from pedicled transverse rectus abdominis myocutaneous (TRAM) flap to deep inferior epigastric perforator (DIEP) free flap. DIEP flap has the advantage of complete rectus abdominis sparing during harvest, thus decreasing donor site morbidity. Aim of this study is to determine whether the surgical advantages of the DIEP flap impact postoperative outcomes versus the free TRAM flap (fTRAM). METHODS: We reviewed the Nationwide Inpatient Sample database (2010-2011) for all cases of DIEP and fTRAM breast reconstruction...

BACKGROUND: The last few years have witnessed an increasing number of clinical research networks (CRNs) focused on building large collections of data from electronic health records (EHRs), claims, and patient-reported outcomes (PROs). Many of these CRNs provide a service for the discovery of research cohorts with various health conditions, which is especially useful for rare diseases. Supporting patient privacy can enhance the scalability and efficiency of such processes; however, current practice mainly relies on policy, such as guidelines defined in the Health Insurance Portability and Accountability Act (HIPAA), which are insufficient for CRNs (e...
