BACKGROUND Vitamin D deficiency in the perioperative surgical period is associated with inferior surgical outcomes. There are no established preoperative supplementation regimens in the orthopedic literature. The purpose of this study is to compare the efficacy between 2 different supplementation regimens of vitamin D prior to total knee arthroplasty. METHODS We conducted a retrospective analysis of 174 patients identified as vitamin D deficient (25(OH)D < 30 ng/mL) who received one of 2 vitamin D supplementation protocols: (1) daily supplementation with D3 on a sliding scale from 1000 to 6000 IU or (2) a loading dose of 50,000 IU D3 weekly for 4 weeks then 2000 IU/d. Serum vitamin D levels were measured at 3 months and 1 month preoperatively. RESULTS Mean patient age was 65.5(±8.6) years, and 54.6% were female. Deficiency was corrected in 73.3% of patients in the loading dose group and 42.4% of patients in the daily, low-dose group [χ2 (1, N = 174) = 16.53, P < .001]. Patients in the loading dose group also achieved a greater average correction in vitamin D levels. CONCLUSION This is the first study to compare preoperative vitamin D supplementation protocols. A loading dose regimen of 50,000 IU weekly for 4 weeks followed by a maintenance dose of 2000 IU/d more effectively corrects vitamin D deficiency compared to a low-dose, daily regimen among total knee arthroplasty patients. We recommend this regimen for deficiency correction in patients who have been screened to be deficient in vitamin D preoperatively.

OBJECTIVE: To evaluate the effects of gaining access to Medicare on key financial outcomes for surgical patients. SUMMARY BACKGROUND DATA: Surgical care poses a significant financial burden, especially among patients with insufficient financial risk protection. Medicare may mitigate the risk of these adverse circumstances, but the impact of Medicare eligibility on surgical patients remains poorly understood. METHODS: Regression discontinuity analysis of national, cross-sectional survey and cost data from the 2008–2018 National Health Interview Survey (NHIS) and Medical Expenditure Panel Survey (MEPS). Patients were between the ages of 57–72 with surgery in the past 12 months. The primary outcomes were the presence of medical debt, delay/deferment of care due to cost, total annual out-of-pocket (OOP) costs, and experiencing catastrophic health expenditures (CHE). RESULTS: Among 45,982,243 NHIS patients, Medicare eligibility was associated with a 6.6 percentage-point decrease (95%CI: −9.0% to −4.3) in being uninsured (>99% relative reduction), 7.6 percentage-point decrease (24% relative reduction) in having medical debt (95%CI: −14.1% to −1.1%), and 4.9 percentage-point decrease (95%CI: −9.4% to −0.4%) in deferrals/delays in medical care due to cost (28% relative reduction). Among 33,084,967 MEPS patients, annual OOP spending decreased by $1,199 per patient (95%CI: −$1,633 to −$765), a 33% relative reduction, and CHE decreased by 7.3 percentage points (95%CI: −13.6% to −0.1%), a 55% relative reduction. CONCLUSIONS: Medicare may reduce the economic burden of healthcare spending and delays in care for older adult surgical patients. These findings have important implications for policy discussions regarding changing insurance eligibility thresholds for the older adult population.

The purposes of this pilot study are to utilize digital remote monitoring to (a) evaluate the usability and satisfaction of a wireless blood pressure (BP) and heart rate (HR) monitor and (b) determine whether these data can enable safe mobilization at home after same-day discharge (SDD) joint replacement. A population of 23 SDD patients undergoing unicompartmental knee arthroplasty (UKA), total knee arthroplasty (TKA), or total hip arthroplasty (THA) were given a cellular BP/HR monitor, with real-time data capture. Patients took three readings after surgery, observing for specific blood pressure decreases, HR increases, or hypotensive symptoms. If any criteria applied, patients followed a hydration protocol and delayed ambulation. Home coaching was also provided to each patient. Patient experience was surveyed, and responses were assessed using descriptive statistics. Of 18 patients discharged (78%), 17 returned surveys, of which 100% reported successful device operation. The mean “ease of use” rating was 8.9/10; satisfaction with home coaching was 9.7/10; and belief that the protocol improved patient safety was 8.4/10. A total of 27.8% (n = 5) had hypotensive readings and appropriately delayed ambulation. Our pilot findings support the feasibility of and confirm the satisfaction with remote monitoring after SDD arthroplasty. All patients with symptoms of hypotension were successfully remotely managed using a standardized hydration protocol prior to safe mobilization.
