AI Article Synopsis
- The NSQIP and NRD databases provide insights into healthcare quality but have differing sampling methodologies, potentially leading to conflicting findings in research studies.
- In a study analyzing 30-day readmissions after anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF), significant predictors varied notably between the two databases: NSQIP indicated factors like diagnosis and length of stay, while NRD highlighted age and hypertension for ACDF, and alcohol abuse for PLF.
- The discrepancies in predictive factors underline the importance of database methodology and suggest the need for further validation to assess the accuracy of these databases for predicting patient outcomes.
Article Abstract
Background: The National Surgical Quality Improvement Program (NSQIP) and National Readmission Database (NRD) are 2 widely used databases that provide valuable information regarding the quality of health care. However, the 2 differ in sampling methodology, which may result in conflicting findings when used for research studies. The objective of this study is to evaluate the differences regarding predictors of 30-day readmissions after anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF).
Methods: In this case-control study, NSQIP and NRD were queried for patients undergoing elective ACDF and PLF between 2014 and 2015. The outcome of interest was 30-day readmissions following ACDF and PLF, which were unplanned and related to the index procedure. Subsequently, univariable and multivariable analyses were conducted to determine the predictors of 30-day readmissions using both databases.
Results: For ACDF procedures, diagnosis, outpatient status, American Society of Anesthesiologists class, and length of hospital stay were found to be significant predictors of 30-day readmissions in NSQIP, whereas only age and hypertension were significant in NRD. Among patients undergoing PLF procedures, body mass index, functional status, smoking, steroid use, diabetes, dyspnea, dialysis, emergency, discharge to rehab facility, and length of hospital stay were found to be significant predictors of 30-day readmissions in NSQIP, whereas only alcohol abuse and obesity were significant predictors in NRD.
Conclusions: Two databases differed in terms of significant predictors of 30-day readmissions following ACDF and PLF. This difference may emphasize the differences in the sampling methodology. Further analyses, potentially with an institutional validation, are needed to draw conclusions regarding the accuracy of the 2 databases for predictive analytics.

Department of Orthopaedic Surgery, UT Health San Antonio, San Antonio, TX, USA.
Background: Many patients require total knee arthroplasty (TKA) bilaterally; however, there is limited data on bilateral procedures. This study aims to compare medical and surgical complications and hospital-related outcomes between simultaneous and staged bilateral TKA. We hypothesize that staged procedures will have superior outcomes.

Background: The hospital at home (HaH) model has become more prevalent in the American healthcare system due to its ability to decrease acute care costs and readmission risk. Recent publications have provided guidance on optimizing medication management and patient safety by leveraging clinical pharmacy services. There is limited data on pharmacoeconomic impact of HaH implementation, specifically in underinsured patients.

Background: Low family socio-economic status is a known factor that can contribute to increased mortality for patients with cardiovascular disease. However, in developing countries, the prognostic impact of socio-economic level on pediatric HTx is unclear.
Methods: We conducted a retrospective cohort analysis of children younger than 18 years who underwent heart transplantation (HTx) at our center from October 1, 2005, to May 31, 2023.

Background And Aims: Guidelines recommend endoscopic detorsion in cases of sigmoid volvulus without ischemia or perforation, but the timing in which this should be performed is unclear.
Methods: Admissions for sigmoid volvulus in which endoscopic detorsion was performed between 1/2010-4/2024 were retrospectively reviewed. The timing was calculated as the time between when the confirmatory radiologic exam and endoscopic detorsion were performed.
