A Bundled Payment Model for Pediatric Distal Radius Fractures: Defining an Episode of Care.

ABSTRACT: BACKGROUND:Distal radius fractures are the most common fracture of childhood, occurring in ?1 per 100 children annually. Given the high incidence of these fractures, we explored feasibility of a bundled payment model. We determined the total treatment costs for each child and identified components of fracture management that contributed to variations in cost. METHODS:We retrospectively reviewed all hospital and physician costs related to the treatment of closed distal radius fractures at a large academic children's hospital. We included all children age 2 to 15 years treated by an orthopaedic surgeon for an isolated closed distal radius fracture between 2013 and 2015. We compared total treatment costs by fracture management approach. We then estimated the contribution of each component of fracture management to total treatment costs using linear regression. RESULTS:We identified 5640 children meeting the inclusion criteria, of which 4602 (81.6%) received closed treatment without manipulation, 922 (16.3%) underwent closed reduction in the clinic, emergency department, or radiology procedure suite, and 116 (2.1%) underwent treatment in the operating room. The median cost for closed treatment without manipulation was $1390 [interquartile range (IQR) 1029 to 1801], compared with $4263 (IQR, 3740 to 4832) for closed reduction and $9389 (IQR, 8272 to 11,119) for closed reduction and percutaneous pinning (P<0.001). In multivariable regression analysis, fracture management approach and use of the operating room environment were the largest cost drivers (P<0.001, R=0.88). Closed reduction in the clinic or emergency department added $894 (95% confidence interval, 819-969) to treatment costs, while closed reduction in the operating room added $5568 (95% confidence interval, 5224-6297). Location of the initial clinical evaluation, number of radiographic imaging series obtained, and number of orthopaedic clinic visits also contributed to total costs. CONCLUSIONS:Closed pediatric distal radius fractures treated without manipulation show small variations in treatment costs, making them well suited for bundled payment. Bundled payments for these fractures could reduce costs by encouraging adoption of existing evidence-based practices. LEVEL OF EVIDENCE:Level III-therapeutic.

Project description:Distal radius fractures are very common yet controversy exists regarding which require treatment and is reflected by significant variation in surgical intervention rate. Evidence regarding which fractures would benefit from intervention is varied and largely poor quality. This study had three aims; identify which radiographic parameters are clinically important; quantify the threshold of displacement at which intervention should occur and investigate which patient factors influence the decision to intervene. A modified three round Delphi study was carried out and responses were qualitatively analysed. The Delphi panel was composed of three groups of national and international expert surgeons: hand and wrist surgeons, trauma surgeons, and international researchers. 46 participants initially agreed to take part. 43 completed the first round and all then completed three rounds. Participants were asked questions based around case vignettes in patients of three ages (38, 58, 75 years). For all age groups ulnar variance was ranked as the most important extra-articular parameter, step was ranked as the most important intra-articular parameter. Agreed thresholds were the same for all parameters for patients aged 38 and 58. Surgeons would intervene with +2 mm ulnar variance, 10 degrees dorsal tilt, 2mm step and 3mm gap. In patients aged 75 the agreed thresholds were 20 degrees dorsal tilt, 3mm step and 4mm gap, consensus was not achieved for ulnar variance. Mental capacity, pre-injury functional level and medical co-morbidities were ranked as the most important factors influencing the decision to intervene. Qualitative analysis suggested that pre-injury function was the main theme within these factors. Our findings provide useful advice about which parameters should be measured and radiographic thresholds for intervention. These thresholds may then be modified depending on important patient factors. This information can help guide clinicians with management decisions and reduce variation.

Project description:Instability of the distal radioulnar joint (DRUJ) is a complication that can occur following distal radius fracture or malunion. We have observed that residual radial translation of the distal radius, relative to the radial shaft, may be a causal factor of DRUJ instability, even once the traditional radiographic parameters (volar tilt, radial inclination, and ulnar variance) have been restored. Residual radial translation of the distal fragment may cause detensioning of the distal interosseous membrane (IOM) and pronator quadratus with poor apposition between the ulnar head and sigmoid notch. This may potentially lead to persistent instability of the ulnar head following internal fixation. Residual radial translation deformity is at risk of being overlooked by the wrist surgeon as there is no existing radiographic parameter that accurately measures this deformity.In this study, 100 normal wrist radiographs were reviewed by three fellowship-trained orthopedic surgeons to develop a simple and reproducible technique to measure radial translation.Utilizing the method described, the point of intersection between the ulnar cortex of the shaft of the radius and the lunate left a mean average of 45.48% (range 25–73.68%) of the lunate remaining on the radial side. In the majority of cases more of the lunate resided ulnar to this line. High levels of agreement with inter-rater (intraclass coefficients = 0.967) and intra-rater (intraclass coefficients = 0.79) reliability was observed.The results of this study can be used to define a normal standard against which residual radial translation can be measured to assess the reduction of distal radius fractures. This new parameter aids in the development of surgical techniques to correct residual radial translation deformity. In addition, awareness and correction of this potential malreduction at the time of surgery may decrease the need for other procedures on the ulnar side of the wrist to improve DRUJ stability, such as ulnar styloid fixation, TFCC repair, or ligamentous grafting [corrected].

Project description:BackgroundWe examined whether the Comprehensive Care for Joint Replacement (CJR) model was associated with changes in the receipt of joint replacement among people with Alzheimer's disease and related dementias (ADRD) as well as spending, health service use, and postsurgical outcomes among people with ADRD who underwent a joint replacement surgery.MethodsRetrospective cohort study using 2013-2017 Medicare claims and Minimum Data Set. We used a difference-in-differences analysis to compare people with ADRD residing in CJR-participating treatment areas versus nonparticipating control areas on the receipt of joint replacement, episode spending during the index hospitalization and subsequent 90-day post-discharge period, discharges to an institutional post-acute care setting, and readmissions within 90 days of hospital discharge.ResultsOur sample included 3,361,950 Medicare enrollees with ADRD (2,156,995 women [64%]; mean [SD] age, 83 [8.0] years; 2,646,405 white [78%], 344,478 black [10%], 224,010 Hispanic [7%]). The receipt of replacement among people with ADRD changed similarly between CJR-participating treatment and control areas after CJR model was implemented, suggesting no association of CJR model with the receipt of replacement. Among people with ADRD who received joint replacement, the CJR model was associated with a $1029 decrease in spending per episode (95% confidence interval [CI] -$1577, -$481, p < 0.001), a 1.62 percentage point decrease in discharges to an institutional post-acute care setting (95% CI -3.17, -0.07, p = 0.04), but no changes in 90-day readmission (95% CI -2.68, 0.00, p = 0.051).ConclusionsDespite concerns that the CJR model could hinder people with ADRD from receiving joint replacement, the receipt of joint replacement did not change among people with ADRD under CJR. The CJR model was associated with decreased spending for people with ADRD who received joint replacements, driven by reduced discharges to an institutional post-acute care setting, without any changes in 90-day readmission.

Project description:ObjectivesEvaluate the cost of illness associated with the 90-day period following acute myocardial infarction (AMI) and the implication of care pathway (percutaneous coronary intervention [PCI] vs medical management [MM]), in order to assess the potential financial risk incurred by providers for AMI as an episode of care.PerspectiveReimbursement payment systems for acute care episodes are shifting from 30-day to 90-day bundled payment models. Since follow-up care and readmissions beyond the early days/weeks post-AMI are common, financial risk may be transferred to providers.SettingAMI hospitalization Centers for Medicare & Medicaid Services (CMS) standard analytical files between 10/1/2015 and 9/30/2016 were reviewed.MethodsIncluded patients were Medicare beneficiaries with a primary diagnosis of AMI subsequently treated with either PCI or MM. Payments were standardized to remove geographic variation and separated into reimbursements for services during the hospitalization and from discharge to 90 days post-discharge. Results were stratified by Medicare Severity Diagnosis Related Groups (MS-DRGs) individually and grouped between patients treated with MM and PCI. Risk-adjusted likelihood of utilization of post-acute nursing care and all-cause readmission was assessed by logistic regression.ResultsA total of 96,546 patients were included in the analysis. The highest total mean payment (US$32,714) was for MS-DRG 248 (PCI with non-drug-eluting stent with major complication or comorbidity). Total payments were similar between MM and PCI patients, but MM patients incurred the majority of costs in the post-acute period after discharge, with the converse true for PCI patients. MM without catheterization was associated with a twofold increase in risk of requiring post-acute nursing care and 90-day readmission versus PCI (odds ratio [95% confidence interval]: 2.01 [1.92-2.11] and 2.17 [2.08-2.27]). Smaller hospital size, diabetes, peripheral arterial disease, prior AMI, and multivessel disease were predictors of higher healthcare utilization.ConclusionsMS-DRGs associated with the lowest reimbursements (and presumably, lowest costs of inpatient care) incur the highest post-discharge expenditures. As the CMS Bundled Payment for Care Improvement and similar programs are implemented, there will be a need to account for heterogeneous post-discharge care costs. Video abstract (MP4 274659 KB).
