In the merit-based incentive payment system (MIPS), quality measures are considered topped out if national median performance rates are ≥95%. Quality measures worth 10 points can be capped at 7 points if topped out for ≥2 years. This report compares the availability of diagnostic radiology (DR)-related and interventional radiology (IR)-related measures worth 10 points. A total of 196 MIPS clinical quality measures were reviewed on the Center for Medicare and Medicaid Services MIPS website. There are significantly more IR-related measures worth 10 points than DR measures (2/9 DR measures vs 9/12 IR measures; P = .03), demonstrating that clinical IR services can help mixed IR/DR groups maximize their Center for Medicare and Medicaid Services payment adjustment.  相似文献

BackgroundMedically complex patients require more resources and experience higher costs within total joint arthroplasty (TJA) bundled payment models. While risk adjustment would be beneficial for such patients, no tool currently exists which can reliably identify these patients preoperatively. The purpose of this study is to determine if the Hospital Frailty Risk Score (HFRS) is a valid predictor of high-TJA treatment costs.MethodsRetrospective analysis was performed on patients who underwent primary TJA between 2015 and 2020 from a single large orthopedic practice. ICD-10 codes from an institutional database were used to calculate HFRS. Cost data including inpatient, postacute, and episode of care (EOC) costs were collected. Charlson comorbidity index, demographics, readmissions, and complications were analyzed.Results4936 patients had a calculable HFRS and those with intermediate and high scores experienced more frequent readmissions/complications after TJA, as well as higher EOC costs. However, HFRS did not reliably predict EOC costs, yielding a sensitivity of 49% and specificity of 66%. Multivariate analysis revealed that both patient age and sex are superior individual cost predictors when compared with HFRS. Secondary analyses indicated that HFRS more effectively predicts TJA complications and readmissions but is still nonideal for clinical applications.ConclusionHFRS has poor sensitivity as a predictor of high-EOC costs for TJA patients but has adequate specificity for predicting postoperative readmissions and complications. Further research is needed to develop a scale that can appropriately predict orthopedic cost outcomes.  相似文献

BackgroundAs the Center for Medicare and Medicaid (CMS) moves toward bundled payment plans for total joint arthroplasty (TJA), it becomes necessary to reduce factors that increase cost for an episode of care such as readmissions. The goal of this study is to evaluate the payment for observation stay versus readmission for patients who present to the emergency department.MethodsA retrospective review from 2014-2019 was conducted identifying all Medicare patients who had a primary, elective TJA and visited the ED within 90 days postoperatively. If a readmission was one midnight or less or had an equivalent diagnosis to an observation stay patient, it was characterized as a readmission that could have qualified as an observation stay. Using our institution’s average payment for Medicare readmissions and observations, actual and potential savings were calculated.ResultsSixty-nine out of 523 (13.2%) patients were placed under observation, while 454 (86.8%) patients were readmitted. Eighty-six out of 523 (18.9%) patients qualified for observation status. There was an actual savings of 11.8% by placing patients on observation status and readmission rate was decreased by 13.2%. Savings could have increased by a total of 27.7% and readmissions decreased by a total of 29.6% if all patients who qualified had been placed on observation status.ConclusionAt our institution, the implementation of observation stay has led to a savings of 11.8% and a potential total savings of 27.7%. The rate of readmissions was decreased by 13.2% and had the potential to decrease by a total of 29.6%.  相似文献

BackgroundAlternative payment models were set up to increase the value of care for total joint arthroplasty. Currently, total knee arthroplasty (TKA) and total hip arthroplasty (THA) are reimbursed within the same bundle. We sought to determine whether it was appropriate for these cases to be included within the same bundle.MethodsThe data were collected from consecutive patients in a bundled payment program at a single large academic institution. All payments for 90 days postoperatively were included in the episode of care. Readmission rates, demographics, and length of stay were collected for each episode of care.ResultsThere was a significant difference in cost of episode of care between TKA and THA, with the average TKA episode-of-care cost being higher than the average THA episode-of-care cost ($25803 vs $23805, P < .0001). There was a statistically significant difference between the 2 groups between gender, race, medical complexity, disposition outcome, and length of stay. The TKA group trended toward a lower readmission rate (5.3%) compared to the THA group (6.6%).ConclusionThe cost of an episode of care for patients within the bundled payment model is significantly higher for patients undergoing TKA compared with those undergoing a THA. This should be taken into consideration when determining payment plans for patients in alternative payment plans, along with other aspects of risk that need to be considered in order to allow for hospitals to be successful under the bundled payment model.  相似文献

BackgroundThe purpose of this analysis was to evaluate (1) the impact of depression on resource utilization and financial outcomes in bundled total joint arthroplasty (TJA) and (2) whether similar effects are seen using baseline patient-reported outcome scores.MethodsAll elective bundled TJA cases from 2017 to 2018 at an academic system in the New York City area were included. We analyzed variables associated with cost differences seen between patients with and without depression, and between patients with low (<40th percentile) and high baseline (>60th percentile) Veterans RAND 12-Item Health Survey mental component scores (MCSs). We also analyzed whether depression or low MCS could predict worse financial outcomes.ResultsOur population included 825 patients, 418 with patient-reported outcome scores data. Depression was associated with higher rates of skilled nursing facility (SNF) discharge (42.7% vs 36.5%, P = .04), SNF payments ($16,200 vs $12,100, P = .0002), and average total episode costs ($31,000 vs $27,000, P = .04). Depression predicted bundle cost to be greater than target price (OR 1.82, 95% CI: 1.04-.16; P = .04) and SNF payment greater than 75th percentile (OR: 1.91; 95% CI: 1.00-3.65; P < .05). Similar effects were not seen using MCS.ConclusionThis is the first study to determine that depression predicts bundle cost greater than target price and SNF payment greater than 75th percentile. Our results emphasize the importance of accurate preoperative assessment of mental health in optimization of care, focusing on attenuating the increased SNF payments associated with depression. As similar effects were not seen using MCS, future studies should analyze the use of validated screening tools for depression, such as the PHQ-9, for more accurate assessments of patient mental health in TJA.  相似文献

It is widely accepted that environmental degradation and poverty are linked and that conservation and poverty reduction should be tackled together. However, success with integrated strategies has been elusive. Here, we present the results of a study that illustrates how development that combines environmental and economic perspectives and that provides appropriate compensation to affected populations can improve both nature and society, thereby eradicating the “poverty trap.” The results show that if we cannot improve the livelihood of local residents, we will be unable to restore degraded environments when state-owned property is transferred to private ownership to encourage better management by residents. In contrast, measures to eliminate poverty, combined with the development of green enterprises that improve the livelihoods of private land owners in the long term, is the precondition for successful ecological restoration.  相似文献
