Early mobilization versus plaster immobilization of simple elbow dislocations: a cost analysis of the FuncSiE multicenter randomized clinical trial.

INTRODUCTION: The primary aim was to assess and compare the total costs (direct health care costs and indirect costs due to loss of production) after early mobilization versus plaster immobilization in patients with a simple elbow dislocation. It was hypothesized that early mobilization would not lead to higher direct and indirect costs. MATERIALS AND METHODS: This study used data of a multicenter randomized clinical trial (FuncSiE trial). From August 25, 2009 until September 18, 2012, 100 adult patients with a simple elbow dislocation were recruited and randomized to early mobilization (immediate motion exercises; n = 48) or 3 weeks plaster immobilization (n = 52). Patients completed questionnaires on health-related quality of life [EuroQoL-5D (EQ-5D) and Short Form-36 (SF-36 PCS and SF-36 MCS)], health care use, and work absence. Follow-up was 1 year. Primary outcome were the total costs at 1 year. Analysis was by intention to treat. RESULTS: There were no significant differences in EQ-5D, SF-36 PCS, and SF-36 MCS between the two groups. Mean total costs per patient were €3624 in the early mobilization group versus €7072 in the plaster group (p = 0.094). Shorter work absenteeism in the early mobilization group (10 versus 18 days; p = 0.027) did not lead to significantly lower costs for loss of productivity (€1719 in the early mobilization group versus €4589; p = 0.120). CONCLUSION: From a clinical and a socio-economic point of view, early mobilization should be the treatment of choice for a simple elbow dislocation. Plaster immobilization has inferior results at almost double the cost.

Direct Health Care Cost and Work Incapacity Related to Complex Regional Pain Syndrome in Switzerland: A Retrospective Analysis from 2008 to 2015.

OBJECTIVE: First, to determine the number of accident-related complex regional pain syndrome (CRPS) cases from 2008 to 2015 and to identify factors associated with an increased risk for developing CRPS. Second, to analyze the duration of work incapacity and direct health care costs over follow-up periods of two and five years, respectively. DESIGN: Retrospective data analysis. SETTING: Database from the Statistical Service for the Swiss National Accident Insurances covering all accidents insured under the compulsory Swiss Accident Insurance Law. SUBJECTS: Subjects were registered after an accident between 2008 and 2015. METHODS: Cases were retrospectively retrieved from the Statistical Service for the Swiss National Accident Insurances. Cases were identified using the appropriate International Classification of Diseases, 10th Revision, codes. RESULTS: CRPS accounted for 0.15% of all accident cases. Age, female gender (odds ratio [OR] = 1.53, 95% confidence interval [CI] = 1.47-1.60), and fracture of the forearm (OR = 38, 95% CI = 35-42) were related to an increased risk of developing CRPS. Over five years, one CRPS case accumulated average insurance costs of $86,900 USD and treatment costs of $23,300 USD. Insurance costs were 19 times and treatment costs 13 times the average costs of accidents without CPRS. Within the first two years after the accident, the number of days lost at work was 20 times higher in patients with CRPS (330 ± 7 days) than in patients without CRPS (16.1 ± 0.1 days). Two-thirds of all CRPS cases developed long-term work incapacity of more than 90 days. CONCLUSION: CRPS is a relatively rare condition but is associated with high direct health care costs and work incapacity.

Cost-effectiveness model comparing dual-mobility to fixed-bearing designs for total hip replacement in France.

BACKGROUND: Instability is among the main causes of total hip arthroplasty (THA) failure. In clinical studies, THA with a dual-mobility cup (THA-DM) decreased the risk of instability after primary THA compared to THA with a fixed-bearing design (THA-FB). However, whether THA-DM is more cost-effective than THA-FB has not been established using Markov modelling with determination of the incremental cost-effectiveness ratio (ICER). The objectives of this work were to: (1) measure the efficiency of these two options, (2) use the nationwide hospital electronic database (PMSI) to estimate direct costs of dislocations and revisions for instability, and (3) conduct deterministic and probabilistic sensitivity analyses to estimate potential mean annual cost-savings in France. HYPOTHESIS: We hypothesised that primary THA-DM was cost-saving compared to primary THA-FB. MATERIAL AND METHODS: In the database, we identified 80,405 patients who had THA in 2009 and we collected their outcomes over 4 years (2009-2012). Cost-effectiveness was assessed based on the costs of resources used for all consequences of prosthetic dislocation and paid for by the statutory health insurance system or other sources. RESULTS: THA-DM was associated with a relative risk of dislocation of 0.4 versus THA-FB. This risk difference translated into 3283 fewer dislocations per 100,000 patients with THA-DM. The corresponding cost-savings for the 140,000 primary THA procedures done in France annually was 39.62 million Euros. A relative risk of 0.2 would yield annual cost-savings of 56.28 million Euros. In the probabilistic sensitivity analysis, THA-DM was the less costly option under all hypotheses, with potential maximum cost-savings of more than 100 million Euros per year in France. DISCUSSION: This comparative cost-effectiveness analysis suggests that THA-DM may induce substantial cost-savings compared to THA-FB. This possibility should be assessed by long-term clinical studies of new-generation DM prostheses.

The Relationship of Obesity to Increasing Health-Care Burden in the Setting of Orthopaedic Polytrauma.

BACKGROUND: With the rise of obesity in the American population, there has been a proportionate increase of obesity in the trauma population. The purpose of this study was to use a computed tomography-based measurement of adiposity to determine if obesity is associated with an increased burden to the health-care system in patients with orthopaedic polytrauma. METHODS: A prospective comprehensive trauma database at a level-I trauma center was utilized to identify 301 patients with polytrauma who had orthopaedic injuries and intensive care unit admission from 2006 to 2011. Routine thoracoabdominal computed tomographic scans allowed for measurement of the truncal adiposity volume. The truncal three-dimensional reconstruction body mass index was calculated from the computed tomography-based volumes based on a previously validated algorithm. A truncal three-dimensional reconstruction body mass index of <30 kg/m(2) denoted non-obese patients and ≥ 30 kg/m(2) denoted obese patients. The need for orthopaedic surgical procedure, in-hospital mortality, length of stay, hospital charges, and discharge disposition were compared between the two groups. RESULTS: Of the 301 patients, 21.6% were classified as obese (truncal three-dimensional reconstruction body mass index of ≥ 30 kg/m(2)). Higher truncal three-dimensional reconstruction body mass index was associated with longer hospital length of stay (p = 0.02), more days spent in the intensive care unit (p = 0.03), more frequent discharge to a long-term care facility (p < 0.0002), higher rate of orthopaedic surgical intervention (p < 0.01), and increased total hospital charges (p < 0.001). CONCLUSIONS: Computed tomographic scans, routinely obtained at the time of admission, can be utilized to calculate truncal adiposity and to investigate the impact of obesity on patients with polytrauma. Obese patients were found to have higher total hospital charges, longer hospital stays, discharge to a continuing-care facility, and a higher rate of orthopaedic surgical intervention.

Acute care costs in overweight children: a pediatric urban cohort study.

BACKGROUND: Evidence indicates obese children have increased health care utilization. It is unknown if this is true within the emergency department (ED) setting. Our purpose is to determine if overweight children presenting for emergency care have increased resource utilization over normal weight peers. METHODS: We conducted a retrospective cohort study of children 2 to <18 years old presenting to a pediatric ED in 2007. Overweight was defined as >95th percentile sex-specific weight-for-age, and normal weight was defined as ≤95(th) percentile. We used a subsample validation to compare these study definitions to BMI-based definitions. We compared total billed charges and secondary outcomes of ED length of stay and admission rate using multivariate and logistic regression models. Outcomes were reported for admitted and discharged patients. Four diagnoses were examined for primary and secondary outcomes. RESULTS: Of 32,996 included visits, 6333 (19.2%) were for overweight children. Study definitions correctly classified 98.3% of normal weight children but only 51.3% of overweight children. Overweight children were more likely to be older, black, and publicly insured. Median charges for overweight and normal weight children, whether discharged or admitted, were not different in the adjusted model. Admitted overweight children with asthma and fractures or dislocations had higher median charges than normal weight $4617 (2065-375,669) versus $4177 (1980-37,432, p=0.01) and $9855 (6681-58,546) versus $8137 (1461-52,557, p=0.01), respectively. CONCLUSIONS: Overall acute care costs for overweight children are not different from normal weight children. However, admitted overweight children have disease-specific increased use of resources.

Epidemiological survey of orthopedic joint dislocations based on nationwide insurance data in Taiwan, 2000-2005.

BACKGROUND: The epidemiology of acute orthopedic dislocations is poorly understood. A nationwide database provides a valuable resource for examining this issue in the Taiwanese population. METHODS: A 6-year retrospective cohort study of 1,000,000 randomly-sampled beneficiaries from the year 2005 was used as the original population. Based on the hospitalized and ambulatory data, the concomitant ICD9-CM diagnosis codes and treatment codes were evaluated and classified into 8 and 3 major categories, respectively. The cases matching both inclusive criteria of dislocation-related diagnosis codes and treatment codes were defined as incident cases. RESULTS: During 2000-2005, the estimated annual incidence (per 100,000 population) of total orthopedic dislocations in Taiwan was 42.1 (95%CI: 38.1-46.1). The major cause of these orthopedic dislocations was traffic accidents (57.4%), followed by accident falls (27.5%). The annual incidence dislocation by location was shoulder, 15.3; elbow, 7.7; wrist, 3.5; finger, 4.6; hip, 5.2; knee, 1.4; ankle, 2.0; and foot, 2.4. Approximately 16% of shoulder dislocations occurred with other concomitant fractures, compared with 17%, 53%, 16%, 76% and 52%, respectively, of dislocated elbow, wrist, hip, knee, and ankle cases. Including both simple and complex dislocated cases, the mean medical cost was US$612 for treatment of a shoulder dislocation, $504 for the elbow, $1,232 for the wrist, $1,103 for the hip, $1,888 for the knee, and $1,248 for the ankle. CONCLUSIONS: In Taiwan, three-quarters of all orthopedic dislocations were of the upper limbs. The most common complex fracture-dislocation was of the knee, followed by the wrist and the ankle. Those usually needed a treatment combined with open reduction of fractures and resulted in a higher direct medical expenditure.

A retrospective review over 1999 to 2007 of head, shoulder and knee soft tissue and fracture dislocation injuries and associated costs for rugby league in New Zealand.

King et al. reported that of 5 941 moderate to serious claims resulting in medical treatment for rugby league injuries, the knee, shoulder, and head and neck body sites and soft tissue and fracture-dislocation injuries were most frequent and costly in the New Zealand national no-fault injury compensation corporation database during 1999 to 2007. However, additional analyses of knee, shoulder and head and neck body sites by soft tissue and fracture-dislocation injury types was required to enable a greater understanding of the nature of injuries most likely to be seen by sports medical personnel dealing with rugby league players. From 1999 to 2007 the injury claims and costs for head and neck soft tissue, fracture-dislocations, shoulders soft tissue significantly increased. Knee soft tissue injury claims and costs significantly decreased from 1999 to 2007. There was no significant difference in knee fracture-dislocation injury claims but there was a significant increase in knee fracture-dislocation injury costs from 1999 to 2007. Changes in the nature of injuries may be related to changes in defensive techniques employed in rugby league during this time. Sports medical personnel dealing with rugby league players should focus their injury prevention strategies on reducing musculoskeletal injuries to the head and shoulder. There should be a focus on increasing awareness of correct tackling technique, head injury awareness and management of suspected cervical spine injuries.

[Epidemiology and economic implications of fractures of proximal femur, proximal humerus, distal radius and fracture-dislocation of ankle]. / Epidemiologie a ekonomie zlomenin proximálního femuru, proximálního humeru, distálního radia a luxacních zlomenin hlezna.

The authors analyze the results of their long-term follow-up of basic epidemiological characteristics in fractures of proximal humerus (1,464 patients), distal radius (2,514 patients), proximal femur (3,340 patients) and fracture-dislocation of the ankle (1 195 patients). In fractures of the proximal femur, the average age was 78 years; 71.6 years in men and 80.3 years in women; male-female ratio was 27:73. In fractures of the proximal humerus, the average age was 67 years; 58.8 years in men and 71.2 years in women; male-female ratio was 30:70. In fractures of the distal radius, the average age was 59 years; 45.8 years in men and 64.7 years in women; male-female ratio was 29:71. In fracture-dislocation of the ankle the average age was 49 years; 43.4 years in men and 54.7 years in women; male-female ratio was 50:50. Until 5th decade men had higher representation in all groups of fractures, starting from 6th decade the ratio changed. Introduction of new implants (locking plate, new generation of nails) for fractures of the distal radius and proximal humerus increased significantly the percentage of patients operated on.

[New possibilities in fracture visualization by means of CT: reconstructions, 3D plannings--difficult joint fractures--modern management--improved visualization and operative planning in joint fractures]. / Neue Möglichkeiten der Visualisierung von Frakturen mittels CT: Rekonstruktionen, 3D-Planungen. Schwierige Gelenkverletzungen--Modernes Management--Verbesserte Bildgebung und Operationsplanung bei Gelenkverletzungen.

After having been introduced in the seventies computed tomography (CT) has become an important instrument for the diagnosis of difficult joint fractures. With the evolution of the Spiral-CT with multiplanar reformations and three-dimensional (3D-) reconstructions the quality of visualization has been improved considerably. In comparison with conventional radiography the actual CT scanners give a clear image of the fracture configuration and the degree of fragment displacement in joint fractures. Additional information about sub-/luxations of the joint, impaction and comminution is also clearly visualized by the CT. This means a rise in quality of fracture classification and enables a detailed view of the fracture pattern. These findings provide the basis for gratifying treatment regimens and surgical management of the injured joint. By the use of innovative reconstruction methods the CT allows exact visualization of internal fixations/osteosynthesis and secondary angular/rotation or length deformities postoperatively. Furthermore, reconstructed 3D-views enable preoperative computer simulated plannings of internal fixations and of reduction control intraoperatively. In fact, the actual Spiral-CT scanners are nearly equivalent in costs and total radiation dose compared to the performance of special projections of conventional radiographs. Thus, we recommend to enlarge the performance of additional CT diagnostic in difficult joint fractures and special pre- or postoperative cases.

HARM 2000: crash cost and consequence data for the new millennium.

This paper presents the most detailed and current costs per US motor vehicle crash victim. These unit costs, which include the first keyed to AIS90, are reported by category, body part, whether a fracture/dislocation was involved, and MAIS. This level of detail allows for reliable analyses of interventions targeting narrow ranges of injuries and, hopefully, for the development of a biomechanical injury cost model.

Time off work due to scaphoid fractures and other carpal injuries in The Netherlands in the period 1990 to 1993.

This study assessed the epidemiology, treatment, disability and time off work due to carpal injuries in the Netherlands in the period from 1990 to 1993. Most injuries were scaphoid fractures and carpal instabilities were rare. The time off work was considerable (mean, 155 days; median, 105 days; range, 12-1708 days). Patients with non-scaphoid fractures had the shortest time off work, followed by those with scaphoid fractures; patients with carpal instabilities had the longest time off work. Despite the significant time off work, the prognosis for return to work was excellent.

Geographic variation in expenditures for Workers' Compensation hospitalized claims.

OBJECTIVE: Past literature finds considerable variation in the cost of physician care and in the utilization of medical procedures. Variation in the cost of hospitalized care has received little attention. We examine injury costs of hospitalized claims across states. DESIGN: Multivariate regression analysis is used to isolate state variations, while controlling for personal and injury characteristics, and state characteristics. SETTING: Injuries to workers filing Workers' Compensation lost workday claims. PARTICIPANTS: About 35,000 randomly sampled Workers' Compensation claims from 17 states filed between 1979 and 1988. MAIN OUTCOME MEASURE: Medical payments per episode of three injury groups: upper and lower extremity fractures and dislocations, other upper extremity injuries, and back strains and sprains. RESULTS: Statistical analyses reveal considerable variation in expenditures for hospitalized injuries across states, even after controlling for case mix and state characteristics. A substantial portion of the variation is explained by state rate regulations; regulated states have lower costs. CONCLUSIONS: The large variation in costs suggests a potential to affect the costs of hospitalized care. Efforts should be directed at those areas that have higher costs without sufficient input price, quality, or case mix justification.

Displaced fractures of the femoral shaft in children. Unique features and therapeutic options.

The decision analysis for managing femoral shaft fractures in children should included such factors as the possibility of child abuse, overgrowth, and the potential for remodeling. Direct and indirect costs must be understood. Factors to consider in determining treatment include the age of the child, the extent of the soft tissue injury, and associated injuries. Non-operative methods, universally used in the past to treat these injuries, still are indicated, but operative modalities should be considered for a greater number of pediatric femoral fractures. Early enthusiasm for external fixation and rigid intramedullary rodding has been tempered by a greater awareness of their particular complications. The role of flexible intramedullary rodding, however, is expanding.

[Acromioclavicular joint injuries: efficient therapy from the economic viewpoint]. / Schultereckgelenkverletzungen: Effiziente Therapie unter ökonomischen Aspekten.

The results of surgical treatment with tension band wiring versus conservative therapy with bandages are described in a retrospective study. Operative therapy is associated with complications in 32.3% and two occasions of hospitalisation. The advantages of conservative therapy are obvious: it is easy and comfortable for the patient; there are no complications and low costs, and it is associated with a shorter temporary disablement. Therefore, conservative therapy is our standard, and surgery is performed only for Rockwood IV-VI lesions and in exceptional cases.

Scapulothoracic dissociation: a devastating injury.

Scapulothoracic dissociation, although rare, causes significant morbidity and mortality by completely disrupting the attachments of the scapula to the axial skeleton with the skin remaining intact. The defining constellation of injuries is subclavian or axillary vascular disruption, lateral displacement of the scapula, separation of the clavicular articulations with or without fracture of the clavicle, and cervical nerve root avulsion or brachial plexus injury. Orthopedic stabilization, vascular repair, and brachial plexus exploration are mandatory. Above elbow amputation, either primarily or within 24 hours, is recommended for the flail extremity.

The effect of regional trauma care systems on costs.

OBJECTIVE: To assess cost savings from regional trauma care systems. DESIGN: Multivariate regression analysis is used to isolate the effects of regional trauma care systems on medical costs while controlling for personal and injury characteristics and other factors likely to influence medical costs. Percentage reductions in costs are translated into dollar cost savings with corrections for excluded costs and losses from premature death. SETTING: Injuries to workers filing workers' compensation lost workday claims. PARTICIPANTS: Randomly sampled workers' compensation claims from 17 states filed between 1979 and 1988 (N = 217,000). MAIN OUTCOME MEASURE: Medical payments per episode of four injury groups: lower-extremity fractures and dislocations, upper-extremity fractures and dislocations, other upper-extremity injuries, and back strains and sprains. We distinguish hospitalized from nonhospitalized claims. RESULTS: Statistical analyses reveal that states with trauma care systems have 15.5% lower costs per hospitalized injury episode. Savings average $1025 per case in 1988 dollars. Costs per episode for disabling nonhospitalized injury are 10% lower in states with trauma care systems, with savings averaging $75 per case. The largest savings are for back injuries. CONCLUSIONS: Extending trauma care systems nationwide could lower annual medical care payments by $3.2 billion. Including productivity losses due to premature death, the savings could total $10.3 billion, 5.9% of national injury costs.

The medical and economic impact of closed cervical spine dislocations.

The current study examined the medical and economic impact of various treatment modalities of unstable cervical spine dislocations. Thirty-five patients with dislocations of the cervical spine were reviewed retrospectively from two large university hospitals. There were 23 unilateral and 12 bilateral facet dislocations. Fourteen patients were treated nonoperatively and 21 patients were treated with early surgery. Nine of the 14 patients treated nonoperatively redisplaced their dislocations while in an orthosis and required late surgery. Analysis of variance shows that it is the amount of injury (unilateral versus bilateral) that results in statistically significant difference in the injury severity score, Glasgow coma scale, trauma motor index, and the number of complications. Of the treatment groups (operative versus nonoperative), the operative group showed a statistically significant difference in the length of hospital stay. Also noted in the operative group was less traction time, earlier erect physical therapy, an average financial savings of $18,407.00, and equal morbidity or mortality to the nonoperative treatment group. Based on this limited experience, it would appear that "diagnosis related groups" are not capable of supporting traumatic spinal care and, if adopted by other states and third party payers, the concept of trauma and/or spinal cord injury centers may be in jeopardy.

Reliability of indications for cervical spine films in trauma patients.

Common emergency room practice mandates cervical spine (C-spine) films in all trauma patients with potential injuries. With the increasing costs of medical care, such liberal criteria may not be justified. This 1-year prospective study of 860 patients who presented to a Level I Trauma Center was undertaken to determine the signs and symptoms that would select the patients at risk of C-spine injury. The clinical presentation of each patient was correlated with the presence of C-spine fracture. Twenty-four patients (2.8%) had injuries demonstrated by plain film radiography. The incidence of fracture in 536 symptomatic patients was 4%. A significant likelihood of C-spine fracture was seen in patients with respiratory compromise (100%), motor dysfunction (54.5%), and altered sensorium (8.9%) (p less than 0.001). No fractures were seen in asymptomatic patients (p less than 0.001). Cervical spine radiography should be performed in patients with abnormal neurologic findings or symptoms referable to the neck. In alert asymptomatic patients, cervical spine radiography may be omitted.

[Rehabilitative treatment in old and inveterate fracture-dislocations of the bones of the feet]. / Vosstanovitel'noe lechenie nesvezhikh i zastarelykh perelomovyvikhov kostei stop.

The authors present the dynamics of the clinico-roentgenologic and biomechanical results of the treatment of 57 patients with late and inveterate dislocation fractures of the bones of the foot using the method of distraction. The analysis of the economic damage has demonstrated that a continuous disturbance in the working ability of the patients with this pathology causes an economic damage to the state averaging 7043.3 +/- 259.2 rubles. The favourable anatomic and functional results obtained in the absolute majority of the patients testify to the effectiveness of the method of distraction treatment.
