BACKGROUND Identifying risk factors for inferior outcomes after anterior cruciate ligament reconstruction (ACLR) is important for prognosis and future treatment. HYPOTHESIS Articular cartilage lesions and meniscus tears/treatment would predict International Knee Documentation Committee (IKDC) score, Knee injury and Osteoarthritis Outcome Score (KOOS) (all(More)
BACKGROUND Although rare, infection can be devastating after anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to test the association between infection after ACL reconstruction and potential risk factors such as age, body mass index (BMI), smoking, diabetes, and graft choice. METHODS We reviewed the Multicenter Orthopaedic(More)
OBJECTIVE To examine the association of patient- and medication-related factors with postdischarge medication errors. PATIENTS AND METHODS The Vanderbilt Inpatient Cohort Study includes adults hospitalized with acute coronary syndromes and/or acute decompensated heart failure. We measured health literacy, subjective numeracy, marital status, cognition,(More)
BACKGROUND With the shift of our healthcare system toward a value-based system of reimbursement, complications such as surgical site infections (SSI) may not be reimbursed. The purpose of our study was to investigate the costs and risk factors of SSI for orthopedic trauma patients. METHODS Through retrospective analysis, 1819 patients with isolated(More)
BACKGROUND Healthcare-associated transmission of respiratory viruses is a concerning patient safety issue. DESIGN Surveillance for influenza virus among a cohort of healthcare workers (HCWs) was conducted in a tertiary care children's hospital from November 2009 through April 2010 using biweekly nasal swab specimen collection. If a subject reported(More)
BACKGROUND, OBJECTIVE Patients' self-reported preparedness for discharge has been shown to predict readmission. It is unclear what differences exist in the predictive abilities of 2 available discharge preparedness measures. To address this gap, we conducted a comparison of these measures. DESIGN, SETTING, PATIENTS Adults hospitalized for cardiovascular(More)
Little research has examined the association of health literacy and numeracy with patients' preferred involvement in the problem-solving and decision-making process in the hospital. Using a sample of 1,249 patients hospitalized with cardiovascular disease from the Vanderbilt Inpatient Cohort Study (VICS), we assessed patients' preferred level of involvement(More)
BACKGROUND Knees undergoing revision anterior cruciate ligament reconstruction (rACLR) have a high prevalence of articular cartilage lesions. HYPOTHESIS The prevalence of chondrosis at the time of rACLR is associated with meniscal status and lower extremity alignment. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Data from the(More)
BACKGROUND Shoulder instability is a common cause of pain and dysfunction in young, active patients. While studies have analyzed risk factors for recurrent instability and failure after instability surgery, few have examined which variables are associated with initial surgery in this patient population. PURPOSE To identify variables that may be associated(More)
We sought to conduct the largest retrospective study to date of open tibia fractures and describe the incidence of complications and evaluate the potential predictive risk factors for complications. Patients with open tibia fractures treated with reamed intramedullary nail (IMN) across a 10-year period were evaluated. Patient charts were reviewed for(More)
