Joel J Gagnier, Hal Morgenstern
The interpretation and reporting of p values and significance testing in biomedical research are fraught with misconceptions and inaccuracies. Publications of peer-reviewed research in orthopaedics are not immune to such problems. The American Statistical Association (ASA) recently published an official statement on the use, misuse, and misinterpretation of statistical testing and p values in applied research. The ASA statement discussed 6 principles: (1) "P-values can indicate how incompatible the data are with a specified statistical model...

OBJECTIVE: The American Academy of Orthopaedic Surgeons (AAOS) recently published appropriateness criteria for patients with knee osteoarthritis (OA) who are being considered for total knee arthroplasty (TKA). We evaluated the extent to which predictor variables used by the AAOS contribute to final classification, rated as "appropriate," "may be appropriate" or "rarely appropriate." METHODS: The RAND/UCLA Appropriateness method was used by AAOS to develop 864 clinical vignettes, each incorporating eight evidence-based variables associated with TKA outcome or need...

INTRODUCTION: As the United States healthcare system evolves towards improved value delivery, patient outcomes and healthcare costs are increasingly used to evaluate physicians and provider organizations. One such metric is hospital length of stay, which has the potential to be influenced by a variety of patient characteristics and comorbidities. Determining factors influencing length of stay represents an opportunity to increase value in healthcare delivery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database (2006-2012) was utilized to identify a cohort of 92,266 patients having one of 14 common orthopaedic procedures...

INTRODUCTION: Pneumonia is the third most common postoperative complication. However, its epidemiology varies widely and is often difficult to assess. For a better understanding, we utilized two national databases to determine the incidence of postoperative pneumonia after various surgical procedures. Specifically, we used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and the Nationwide Inpatient Sample (NIS) to determine the incidence and yearly trends of postoperative pneumonia following orthopaedic, urologic, otorhinolaryngologic, cardiothoracic, neurosurgery, and general surgeries...

BACKGROUND: While glenoid retroversion and posterior humeral head decentering are common preoperative features of severely arthritic glenohumeral joints, the relationship of postoperative glenoid component retroversion to the clinical results of total shoulder arthroplasty (TSA) is unclear. Studies have indicated concern for inferior outcomes when glenoid components are inserted in 15° or more retroversion. QUESTIONS/PURPOSES: In a population of patients undergoing TSA in whom no specific efforts were made to change the version of the glenoid, we asked whether at 2 years after surgery patients having glenoid components implanted in 15° or greater retroversion had (1) less improvement in the Simple Shoulder Test (SST) score and lower SST scores; (2) higher percentages of central peg lucency, higher Lazarus radiolucency grades, higher mean percentages of posterior decentering, and more frequent central peg perforation; or (3) a greater percentage having revision for glenoid component failure compared with patients with glenoid components implanted in less than 15° retroversion...

An Institute of Medicine report published in 2000 brought attention to the devastating consequences of medical errors. The report estimated that 98,000 deaths occurred in US hospitals each year as a result of medical errors and spawned investigations into factors that are associated with medical errors as well as strategies to avoid them. Taking cues from high-reliability organizations, such as the airline industry, evidence-based tools were developed to minimize human risk factors and foster teamwork, communication, and other skills that are essential to patient safety and quality...
