The Impact of COVID-19 on Postdischarge Outcomes for Dialysis Patients in the United States: Evidence from Medicare Claims Data.

Background: Recent investigations have shown that, on average, patients hospitalized with coronavirus disease 2019 (COVID-19) have a poorer postdischarge prognosis than those hospitalized without COVID-19, but this effect remains unclear among patients with end-stage kidney disease (ESKD) who are on dialysis. Methods: Leveraging a national ESKD patient claims database administered by the US Centers for Medicare and Medicaid Services, we conducted a retrospective cohort study that characterized the effects of in-hospital COVID-19 on all-cause unplanned readmission and death within 30 days of discharge for patients on dialysis. Included in this study were 436,745 live acute-care hospital discharges of 222,154 Medicare beneficiaries on dialysis from 7871 Medicare-certified dialysis facilities between January 1 and October 31, 2020. Adjusting for patient demographics, clinical characteristics, and prevalent comorbidities, we fit facility-stratified Cox cause-specific hazard models with two interval-specific (1-7 and 8-30 days after hospital discharge) effects of in-hospital COVID-19 and effects of prehospitalization COVID-19. Results: The hazard ratios due to in-hospital COVID-19 over the first 7 days after discharge were 95% CI, 1.53 to 1.65 for readmission and 95% CI, 1.38 to 1.70 for death, both with P<0.001. For the remaining 23 days, the hazard ratios were 95% CI, 0.89 to 0.96 and 95% CI, 0.86 to 1.07, with P<0.001 and P=0.50, respectively. Effects of prehospitalization COVID-19 were mostly nonsignificant. Conclusions: In-hospital COVID-19 had an adverse effect on both postdischarge readmission and death over the first week. With the surviving patients having COVID-19 substantially selected from those hospitalized, in-hospital COVID-19 was associated with lower rates of readmission and death starting from the second week.

Drains Are Not Beneficial in Primary Shoulder Arthroplasty.

The purpose of this study was to determine if clinical differences exist between closed drainage use in primary shoulder arthroplasty and postoperative complications. A retrospective review was performed of all primary total shoulder and reverse total shoulder arthroplasty procedures at the authors' institution during a 2-year period. A total of 378 of 636 shoulder arthroplasty patients met inclusion criteria. Drains were used in 111 patients. The authors did not identify a significant relationship between drain use and postoperative complications. When complications were stratified just by the presence or absence of risk factors, irrespective of whether a drain was used, no significant relationship was identified. This study does not support the routine use of closed drainage systems in primary shoulder arthroplasty, including for patients with risk factors for potentially developing postoperative complications.

Publication rate of presentations at an annual military orthopaedic meeting.

Many research abstracts presented at orthopaedic conferences do not undergo a formal editorial, or peer-review process; however, abstracts are frequently referenced in textbooks and influence clinical practice. The purpose of this study was to determine the publication rate of abstracts formally presented at the Society of Military Orthopaedic Surgeons (SOMOS) annual meetings from 1998 to 2006 that went to full-text publication. Using Google Scholar and PubMed, a literature search was performed for each abstract presented at the annual SOMOS meeting in the years 1998-2006, to calculate the overall full-text publication rate, the average duration from presentation to publication, and the distribution of publications in the various journals. A total of 770 abstracts were presented at the annual SOMOS meetings. The overall full-text publication rate at a minimum of 3 years was 45.7% (352 publications). The average time from presentation to publication was 2.7 years. The published articles appeared in 65 peer-reviewed journals, with notable distribution in Spine (10.0%), The American Journal of Sports Medicine (9.4%), and The Journal of Bone and Joint Surgery (9.4%). The full-text publication rate of abstracts presented at the annual SOMOS meetings compares favorably with that of other major orthopaedic conferences in the United States. Nonetheless, more than half of abstracts presented at the SOMOS meetings remain unpublished.
