RESUMEN
The COVID-19 pandemic had wide-reaching effects on healthcare delivery, including care for hip fractures, a common injury among older adults. This study characterized factors related to surgical timing and outcomes, length-of-stay, and discharge disposition among patients treated for operative hip fractures during the first wave of the COVID-19 pandemic, compared to historical controls. A retrospective, observational cohort study was conducted from 16 March-20 May 2020 with a consecutive series of 64 operative fragility hip fracture patients at three tertiary academic medical centers. Historical controls were matched based on sex, surgical procedure, age, and comorbidities. Primary outcomes included 30-day mortality and time-to-surgery. Secondary outcomes included 30-day postoperative complications, length-of-stay, discharge disposition, and time to obtain a COVID-19 test result. There was no difference in 30-day mortality, complication rates, length-of-stay, anesthesia type, or time-to-surgery, despite a mean time to obtain a final preoperative COVID-19 test result of 17.6 h in the study group. Notably, 23.8% of patients were discharged to home during the COVID-19 pandemic, compared to 4.8% among controls (p = 0.003). On average, patients received surgical care within 48 h of arrival during the COVID-19 pandemic. More patients were discharged to home rather than a facility with no change in complications, suggesting an opportunity for increased discharge to home.
RESUMEN
BACKGROUND: Postoperative radiographs are commonly ordered after primary total knee arthroplasty (TKA), however, there is limited data on how often these films change management over the entire postoperative time course, and what should prompt imaging to maximize clinical utility. METHODS: A retrospective cohort study was conducted of patients ≥ 18 years old who underwent a primary TKA at two level one trauma centers. Postoperative data were collected to determine the frequency of postoperative radiograph series, radiograph findings that did not suggest normal healing or alignment to radiologist and orthopedists, and changes in postoperative management. The total cost and radiation exposure values were calculated for all patient radiographs using estimates from previous literature. RESULTS: From the 1258 patients included, 3831 postoperative radiographs were taken (mean ± 95% confidence interval [CI]: 3.05 ± 0.11 radiographs per patient). Of these 3831 radiographs, 44 (1.1%) contained a positive radiographic finding. Only 13 (0.3% of radiographs) of these positive radiographic findings were positive orthopaedic findings, 11 of which led to changes in management. For all but 1 of these patients (10/11, 91%), these radiographs were taken during a non-routine postoperative visit. Routine postoperative radiographs that did not change management cost $1,008,480 and administered 22.92 mSV of radiation to patients within this study. CONCLUSION: Postoperative radiography obtained after primary TKA were of low clinical utility yet resulted in considerable healthcare costs and unnecessary radiation burden. Radiographs ordered during a non-routine visit, however, were a reliable indicator of when this imaging provided clinical utility.
