Surgical Complexity and Physician Compensation: An Analysis of Relative Under-Valuation for Pediatric Brachial Plexus Surgery

BACKGROUND

Brachial plexus reconstruction (BPR) is a rapidly advancing field within hand surgery. BPR procedures are complex, time-intensive, and require microsurgical expertise. As physician reimbursement rates for BPR are poorly defined, relative to more common hand procedures, we sought to analyze compensation for BPR across different payor groups and understand the factors contributing to their reimbursement.

METHODS

A retrospective review was performed of surgeries by a single senior staff member in a 4-year period to evaluate Current Procedural Terminology (CPT) codes from BPR cases. For comparison, all finger fracture fixations and skin graft reconstructions performed by the same surgeon over the same time period were analyzed as well.

RESULTS

A total of 57 BPR cases, 94 finger fracture fixation cases, and 69 skin grafting cases met inclusion criteria. Among the top 5 insurance providers, average work relative value unit (wRVU)/hour was 6.55, 3.49, and 12.67 for BPR, fracture fixation, and skin grafts, respectively. Reimbursements were an average $685.76/hour for BPR, compared to $590.10/hour for fracture fixation and $1,197.94/hour for skin grafts.

CONCLUSIONS

BPR demonstrates a relative undervaluation, in terms of reimbursement per hour, given the time and surgical skill required for such cases, particularly compared to shorter, less complex cases such as skin grafting and fracture fixation. We find that this discrepancy is amplified across multiple levels of coding, billing, and reimbursement. We suggest specific strategies for physician leadership to more directly participate in the financial decisions that affect themselves, their patients, and their specialty.

Racial Disparities in the Operative Management of Orthopedic Trauma: A Systematic Review and Meta-Analysis

OBJECTIVE

The objective of this study was to investigate if race is associated with the likelihood of operative management of acute fractures.

METHODS

A systematic review of the literature was performed using the PubMed, EMBASE, and Cochrane databases to identify studies associated with social disparities and acute orthopedic trauma. Peer-reviewed studies commenting on social disparities and the decision to pursue operative or non-operative management of acute fractures were identified for detailed review. Study characteristics and odds ratios were extracted from each article. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed. A quality analysis of the data was also performed.

RESULTS

In total, 13 studies were identified and 8 were included in the meta-analysis totaling 743,846 fractures. Hip, distal radius, pelvic, tibial plateau, clavicle, femoral neck, and femoral shaft fractures were represented in this patient population. The meta-analysis demonstrated that White race is associated with a higher likelihood of operative intervention compared to all other races pooled together (odds ratio, 1.31; 95% confidence interval 1.16 to 1.47; p < .0001) as well as Black race (odds ratio 1.39; 95% confidence interval 1.12 to 1.72; p = .0025).

CONCLUSIONS

Non-White race and Black race are associated with a lower likelihood of receiving surgical management of acute orthopedic trauma. Surgeons and health systems should be aware of these inequities and consider strategies to mitigate bias and ensure all patients receive appropriate and timely care regardless of race.

Nationwide cost-effectiveness analysis of surgical stabilization of rib fractures by flail chest status and age groups

BACKGROUND

Surgical stabilization of rib fracture (SSRF) is increasingly used to manage patients with rib fractures. Benefits of performing SSRF appear variable, and the procedure is costly, necessitating cost-effectiveness analysis for distinct subgroups. We aimed to assess the cost-effectiveness of SSRF versus nonoperative management among patients with rib fractures younger than 65 years versus 65 years or older, with versus without flail chest. We hypothesized that, compared with nonoperative management, SSRF is cost-effective only for patients with flail chest.

METHODS

This economic evaluation used a decision-analytic Markov model with a lifetime time horizon incorporating US population-representative inputs to simulate benefits and risks of SSRF compared with nonoperative management. We report quality-adjusted life years (QALYs), costs, and incremental cost-effectiveness ratios. Deterministic and probabilistic sensitivity analyses accounted for most plausible clinical scenarios.

RESULTS

Compared with nonoperative management, SSRF was cost-effective for patients with flail chest at willingness-to-pay threshold of US $150,000/QALY gained. Surgical stabilization of rib fracture costs US $25,338 and US $123,377/QALY gained for those with flail chest younger than 65 years and 65 years or older, respectively. Surgical stabilization of rib fracture was not cost-effective for patients without flail chest, costing US $172,704 and US $243,758/QALY gained for those younger than 65 years and 65 years or older, respectively. One-way sensitivity analyses showed that, under most plausible scenarios, SSRF remained cost-effective for subgroups with flail chest, and nonoperative management remained cost-effective for patients older than 65 years without flail chest. Probability that SSRF is cost-effective ranged from 98% among patients younger than 65 years with flail chest to 35% among patients 65 years or older without flail chest.

CONCLUSIONS

Surgical stabilization of rib fracture is cost-effective for patients with flail chest. Surgical stabilization of rib fracture may be cost-effective in some patients without flail chest, but delineating these patients requires further study.

What Is the Quality of Surgical Care for Patients with Hip Fractures at Critical Access Hospitals?

BACKGROUND

Critical access hospitals (CAHs) play an important role in providing access to care for many patients in rural communities. Prior studies have shown that these facilities are able to provide timely and quality care for patients who undergo various elective and emergency general surgical procedures. However, little is known about the quality and reimbursement of surgical care for patients undergoing surgery for hip fractures at CAHs compared with non-CAH facilities.

QUESTIONS/PURPOSES

Are there any differences in 90-day complications, readmissions, mortality, and Medicare payments between patients undergoing surgery for hip fractures at CAHs and those undergoing surgery at non-CAHs?

METHODS

The 2005 to 2014 Medicare 100% Standard Analytical Files were queried using ICD-9 procedure codes to identify Medicare-eligible beneficiaries undergoing open reduction and internal fixation (79.15, 79.35, and 78.55), hemiarthroplasty (81.52), and THA (81.51) for isolated closed hip fractures. This database was selected because the claims capture inpatient diagnoses, procedures, charged amounts and paid claims, as well as hospital-level information of the care, of Medicare patients across the nation. Patients with concurrent fixation of an upper extremity, lower extremity, and/or polytrauma were excluded from the study to ensure an isolated cohort of hip fractures was captured. The study cohort was divided into two groups based on where the surgery took place: CAHs and non-CAHs. A 1:1 propensity score match, adjusting for baseline demographics (age, gender, Census Bureau-designated region, and Elixhauser comorbidity index), clinical characteristics (fixation type and time to surgery), and hospital characteristics (whether the hospital was located in a rural ZIP code, the average annual procedure volume of the operating facility, hospital bed size, hospital ownership and teaching status), was used to control for the presence of baseline differences in patients presenting at CAHs and those presenting at non-CAHs. A total of 1,467,482 patients with hip fractures were included, 29,058 of whom underwent surgery in a CAH. After propensity score matching, each cohort (CAH and non-CAH) contained 29,058 patients. Multivariate logistic regression analyses were used to assess for differences in 90-day complications, readmissions, and mortality between the two matched cohorts. As funding policies of CAHs are regulated by Medicare, an evaluation of costs-of-care (by using Medicare payments as a proxy) was conducted. Generalized linear regression modeling was used to assess the 90-day Medicare payments among patients undergoing surgery in a CAH, while controlling for differences in baseline demographics and clinical characteristics.

RESULTS

Patients undergoing surgery for hip fractures were less likely to experience many serious complications at a critical access hospital (CAH) than at a non-CAH. In particular, after controlling for patient demographics, hospital-level factors and procedural characteristics, patients treated at a CAH were less likely to experience: myocardial infarction (3% (916 of 29,058) versus 4% (1126 of 29,058); OR 0.80 [95% CI 0.74 to 0.88]; p < 0.001), sepsis (3% (765 of 29,058) versus 4% (1084 of 29,058); OR 0.69 [95% CI 0.63 to 0.78]; p < 0.001), acute renal failure (6% (1605 of 29,058) versus 8% (2353 of 29,058); OR 0.65 [95% CI 0.61 to 0.69]; p < 0.001), and Clostridium difficile infections (1% (367 of 29,058) versus 2% (473 of 29,058); OR 0.77 [95% CI 0.67 to 0.88]; p < 0.001) than undergoing surgery in a non-CAH. CAHs also had lower rates of all-cause 90-day readmissions (18% (5133 of 29,058) versus 20% (5931 of 29,058); OR 0.83 [95% CI 0.79 to 0.86]; p < 0.001) and 90-day mortality (4% (1273 of 29,058) versus 5% (1437 of 29,058); OR 0.88 [95% CI 0.82 to 0.95]; p = 0.001) than non-CAHs. Further, CAHs also had risk-adjusted lower 90-day Medicare payments than non-CAHs (USD 800, standard error 89; p < 0.001).

CONCLUSION

Patients who received hip fracture surgical care at CAHs had a lower risk of major medical and surgical complications than those who had surgery at non-CAHs, even though Medicare reimbursements were lower as well. Although there may be some degree of patient selection at CAHs, these facilities appear to provide high-value care to rural communities. These findings provide evidence for policymakers evaluating the impact of the CAH program and allocating funding resources, as well as for community members seeking emergent care at local CAH facilities.

Volar locking plate versus external fixation for unstable dorsally displaced distal radius fractures-A 3-year cost-utility analysis

Aim

To investigate the cost-effectiveness of Volar Locking Plate (VLP) compared to External Fixation (EF) for unstable dorsally displaced distal radius fractures in a 3-year perspective.

Methods

During 2009–2013, patients aged 50–74 years with an unstable dorsally displaced distal radius fracture were randomised to VLP or EF. Primary outcome was the incremental cost-effectiveness ratio (ICER) for VLP compared with EF. Data regarding health effects (Quality-adjusted life years, QALYs) was prospectively collected during the trial period until 3 years after surgery. Cost data was collected retrospectively for the same time period and included direct and indirect costs (production loss).

Results

One hundred and thirteen patients (VLP n = 58, EF n = 55) had complete data until 3 years and were used in the analysis. At one year, the VLP group had a mean incremental cost of 878 euros and a gain of 0.020 QALYs compared with the EF group, rendering an ICER of 43 900 euros per QALY. At three years, the VLP group had a mean incremental cost of 1 082 euros and a negative incremental effect of -0.005 QALYs compared to the EF group, which means that VLP was dominated by EF. The probability that VLP was cost-effective compared to EF at three years, was lower than 50% independent of the willingness to pay per QALY.

Conclusion

Three years after distal radius fracture surgery, VLP fixation resulted in higher costs and a smaller effect in QALYs compared to EF. Our results indicate that it is uncertain if VLP is a cost-effective treatment of unstable distal radius fractures compared to EF.

Tibial Shaft Fractures in Workers Compensation and No-Fault Insurance Is There a Difference in Resource Utilization?

BACKGROUND

Workers Compensation claims have been previously associated with inferior clinical outcomes. However, variation in inpatient stays for orthopedic trauma injuries according to insurance type has not been previously examined.

METHODS

We investigated the differences according to insurance for tibial shaft fractures in regard to length of stay and disposition. Using the New York SPARCS database, we identified 1,856 adult non-elderly patients with an isolated tibial shaft fracture who underwent surgery. Patients were stratified by insurance type, including private, Medicaid, Workers Compensation, and no-fault, which covers medical expenses related to automobile or pedestrian accidents.

RESULTS

Compared to private insurance (mean: 2.7 days), length of stay was longer for no-fault (mean: 3.9 days; adjusted difference +33%, p < 0.001) and Medicaid (mean: 3.5 days; adjusted difference +22%, p < 0.001), but not significantly different for Workers Compensation (mean: 3.5 days; adjusted difference +4%, p = 0.474). Compared to private insurance (rate: 3.5%), disposition to a facility was significantly higher for no-fault (rate: 10.1%; adjusted odds ratio [OR] = 3.3, p < 0.001) and Medicaid (rate: 7.6%; OR = 2.2, p = 0.003), but was not significantly different for Workers Compensation (rate: 6.3%; OR = 1.8, p = 0.129).

CONCLUSIONS

Patients with no-fault insurance, but not Workers Compensation, are subject to longer hospital stays and are more likely to be discharged to a facility following operative fixation of an isolated tibial shaft fracture. These findings suggest that financial, social, and legal factors influence medical care for patients involved in automobile accidents with no-fault insurance.

Does pin tract infection after external fixator limits its advantage as a cost-effective solution for open fractures in low-middle income countries, a prospective cohort study

OBJECTIVE

To determine the frequency of pin tract infection in external fixator tibia and its effects on the definite fracture fixation and bone healing.

Methods

The prospective study was conducted at Lady Reading Hospital, Peshawar, Pakistan, from August 2017 to July 2018, and comprised patients regardless of age and gender with open fracture tibia Gustillo-Anderson type II and type IIIA. Pin tract infection was assessed following the application of locally made external fixation of tibia open fractures. Follow-up was done fortnightly till soft tissue healing, removal of external fixator and definite fracture healing. Pin tract infection was classifiedand treated according to the Checketts-Otterburn classification system. SPSS 20 was used for data analysis.

Results

Of the 117 patients, 95(81%) were males and 22(19%) were females with an overall mean age of 24.7±9.35 years. Pin tract infection was documented in 28(23.9%) patients. Minor and major pin tract infections were reported in 27(96.4%) and 1(3.5%) patient respectively. Soft tissues healed in 27(96.4%) cases.

Conclusion

External fixator for initial stabilisation of open tibial fractures in all patients is recommended..

The Cost-Effectiveness of Surgical Fixation of Distal Radial Fractures: A Computer Model-Based Evaluation of Three Operative Modalities

BACKGROUND

There is no consensus on the optimal fixation method for patients who require a surgical procedure for distal radial fractures. We used cost-effectiveness analyses to determine which of 3 modalities offers the best value: closed reduction and percutaneous pinning, open reduction and internal fixation, or external fixation.

METHODS

We developed a Markov model that projected short-term and long-term health benefits and costs in patients undergoing a surgical procedure for a distal radial fracture. Simulations began at the patient age of 50 years and were run over the patient's lifetime. The analysis was conducted from health-care payer and societal perspectives. We estimated transition probabilities and quality-of-life values from the literature and determined costs from Medicare reimbursement schedules in 2016 U.S. dollars. Suboptimal postoperative outcomes were determined by rates of reduction loss (4% for closed reduction and percutaneous pinning, 1% for open reduction and internal fixation, and 11% for external fixation) and rates of orthopaedic complications. Procedural costs were $7,638 for closed reduction and percutaneous pinning, $10,170 for open reduction and internal fixation, and $9,886 for external fixation. Outputs were total costs and quality-adjusted life-years (QALYs), discounted at 3% per year. We considered willingness-to-pay thresholds of $50,000 and $100,000. We conducted deterministic and probabilistic sensitivity analyses to evaluate the impact of data uncertainty.

RESULTS

From the health-care payer perspective, closed reduction and percutaneous pinning dominated (i.e., produced greater QALYs at lower costs than) open reduction and internal fixation and dominated external fixation. From the societal perspective, the incremental cost-effectiveness ratio for closed reduction and percutaneous pinning compared with open reduction and internal fixation was $21,058 per QALY and external fixation was dominated. In probabilistic sensitivity analysis, open reduction and internal fixation was cost-effective roughly 50% of the time compared with roughly 45% for closed reduction and percutaneous pinning.

CONCLUSIONS

When considering data uncertainty, there is only a 5% to 10% difference in the frequency of probability combinations that find open reduction and internal fixation to be more cost-effective. The current degree of uncertainty in the data produces difficulty in distinguishing either strategy as being more cost-effective overall and thus it may be left to surgeon and patient shared decision-making.

Costs of fragility hip fractures globally: a systematic review and meta-regression analysis

Purpose This study was conducted in order to systematically review the costs of hip fractures globally and identify drivers of differences in costs. Methods A systematic review was conducted to identify studies reporting patient level fragility hip fracture costs between 1990 and 2015. We extracted data on the participants and costs from these studies. Cost data concerning the index hospitalisation were pooled, and a meta-regression was used to examine its potential drivers. We also pooled data on the first-year costs following hip fracture and considered healthcare, social care as well as other cost categories if reported by studies. Results One hundred and thirteen studies reported costs of hip fracture based on patient level data. Patients developing complications as well as patients enrolled in intervention arms of comparative studies were found to have significantly higher costs compared to the controls. The pooled estimate of the cost for the index hospitalisation was $10,075. Health and social care costs at 12 months were $43,669 with inpatient costs being their major driver. Meta-regression analysis identified age, gender and geographic region as being significantly associated with the differences in costs for the index hospitalisation. Conclusion Hip fracture poses a significant economic burden and variation exists in their costs across different regions. We found that there was a considerable variation across studies in terms of study design, methodology, follow-up period, costs considered and results reported that highlights the need for more standardisation in this area of research.

Biomechanical and Cost Comparisons of Near-Far and Pin-Bar Constructs

Orthopedic dogma states that external fixator stiffness is improved by placing 1 pin close to the fracture and 1 as distant as possible ("near-far"). This fixator construct is thought to be less expensive than placing pins a shorter distance apart and using "pin-bar" clamps that attach pins to outriggers. The authors therefore hypothesized that the near-far construct is stiffer and less expensive. They compared mechanical stiffness and costs of near-far and pin-bar constructs commonly used for temporary external fixation of femoral shaft fractures. Their testing model simulated femoral shaft fractures in damage control situations. Fourth-generation synthetic femora (n=18) were used. The near-far construct had 2 pins that were 106 mm apart, placed 25 mm from the gap on each side of the fracture. The pin-bar construct pins were 55 mm apart, placed 40 mm from the gap. Mechanical testing was performed on a material test system machine. Stiffness was determined in the linear portion of the load-displacement curve for both constructs in 4 modes: axial compression, torsional loading, frontal plane 3-point bending, and sagittal plane 3-point bending. Costs were determined from a 2012 price guide. Compared with the near-far construct, the pin-bar construct had stiffness increased by 58% in axial compression (P<.05) and by 52% in torsional loading (P<.05). The pin-bar construct increased cost by 11%. In contrast to the authors' hypothesis and existing orthopedic dogma, the near-far construct was less stiff than the pin-bar construct and was similarly priced. Use of the pin-bar construct is mechanically and economically reasonable. [Orthopedics. 2017; 40(2):e238-e241.].

Does Knowledge of Implant Cost Affect Fixation Method Choice in the Management of Stable Intertrochanteric Hip Fractures?

We conducted a study to determine if knowledge of implant cost affects fixation method choice in the management of stable intertrochanteric hip fractures. We retrospectively reviewed the cases of 119 patients treated with a sliding hip screw (SHS; Versafix), a short Gamma nail (SGN), or a long Gamma nail (LGN). Of the 119 fractures, 71 were treated before implant costs were revealed, and 48 afterward. The 2 groups were similar in age, sex, fracture types, American Society of Anesthesiologists physical status classification, and preinjury ambulatory status. SHS was used in 38.0% of the before cases and 27.1% of the after cases, SGN in 29.6% of the before cases and 45.8% of the after cases, and LGN in 32.4% of the before cases and 27.1% of the after cases. Changes in implant use were not statistically significant. SHS was favored for 31-A1.1, 31-A1.2, and 31-A2.1 fractures in the before group but only for 31-A1.2 fractures in the after group. Gamma nails of both sizes were preferred in the after group for 31-A1.1, 31-A1.3, and 31-A2.1 fractures. At our institution, surgeon knowledge of implant cost did not affect fixation method choice in the management of stable intertrochanteric hip fractures.

Operative Cost Comparison: Plating Versus Intramedullary Fixation for Clavicle Fractures

Although clavicle fractures often heal well with nonoperative management, current literature has shown improved outcomes with operative intervention for specific fracture patterns in specific patient types. The 2 most common methods of midshaft clavicle fracture fixation are intramedullary and plate devices. Through retrospective analysis, this study performed a direct cost comparison of these 2 types of fixation at a single institution over a 5-year period. Outcome measures included operative costs for initial surgery and any hardware removal surgeries. This study reviewed 154 patients (157 fractures), and of these, 99 had intramedullary fixation and 58 had plate fixation. A total of 80% (79 of 99) of intramedullary devices and 3% (2 of 58) of plates were removed. Average cost for initial intramedullary placement was $2955 (US dollars) less than that for initial plate placement (P<.001); average cost for removal was $1874 less than that for plate removal surgery (P=.2). Average total cost for all intramedullary surgeries was $1392 less than the average cost for all plating surgeries (P<.001). Average cost for all intramedullary surgeries requiring plate placement and removal was $653 less than the average cost for all plating surgeries that involved only placement (P=.04). Intramedullary fixation of clavicle fractures resulted in a statistically significant cost reduction compared with plate fixation, despite the incidence of more frequent removal surgeries. [Orthopedics.2016; 39(5):e877-e882.].

Impact of hip fracture on hospital care costs: a population-based study

Using a large cohort of hip fracture patients, we estimated hospital costs to be £14,163 and £2139 in the first and second year following fracture, respectively. Second hip and non-hip fractures were major cost drivers. There is a strong economic incentive to identify cost-effective approaches for hip fracture prevention.

INTRODUCTION

The purpose of this study was to estimate hospital costs of hip fracture up to 2 years post-fracture and compare costs before and after the index fracture.

METHODS

A cohort of patients aged over 60 years admitted with a hip fracture in a UK region between 2003 and 2013 were identified from hospital records and followed until death or administrative censoring. All hospital records were valued using 2012/2013 unit costs, and non-parametric censoring methods were used to adjust for censoring when estimating average annual costs. A generalised linear model examined the main predictors of hospital costs.

RESULTS

A cohort of 33,152 patients with a hip fracture was identified (mean age 83 years (SD 8.2). The mean censor-adjusted 1- and 2-year hospital costs after index hip fracture were £14,163 (95 % confidence interval (CI) £14,008 to £14,317) and £16,302 (95 % CI £16,097 to £16,515), respectively. Index admission accounted for 61 % (£8613; 95 % CI £8565 to £8661) of total 1-year hospital costs which were £10,964 higher compared to the year pre-event (p < 0.001). The main predictors of 1-year hospital costs were second hip fracture, other non-hip fragility fractures requiring hospitalisation and hip fracture-related complications. Total UK annual hospital costs associated with incident hip fractures were estimated at £1.1 billion.

CONCLUSIONS

Hospital costs following hip fracture are high and mostly occur in the first year after the index hip fracture. Experiencing a second hip fracture after the index fracture accounted for much of the increase in costs. There is a strong economic incentive to prioritise research funds towards identifying the best approaches to prevent both index and subsequent hip fractures.

Staged Columnar Fixation of Bicondylar Tibial Plateaus: A Cheaper Alternative to External Fixation

The objective of this study was to compare complication rates and costs of staged columnar fixation (SCF) to external fixation for bicondylar tibial plateau fractures. Patients who received SCF or temporary external fixation across a 3-year period at a major level I trauma center underwent a retrospective chart review for associated complications. Fisher's exact analysis was used to determine any statistical difference in complication rates between both groups. However, there was no significant difference in complication rates between the SCF and external fixator groups. Average medial plate costs for SCF were $2131 compared with an average external fixator cost of $4070 (p < .0001). Given that all patients with external fixation undergo eventual medial and lateral plating, savings with SCF include $4070 plus operative costs for removing the fixator. As our health care system focuses on cost-cutting efforts, orthopaedic trauma surgeons must explore cheaper and equally effective treatment alternatives.

Comparison of Outcomes and Costs of Tension-Band and Locking-Plate Osteosynthesis in Transverse Olecranon Fractures: A Matched-Cohort Study

To determine if there are significant differences in outcomes and costs between tension-band and locking-plate fixation of transverse olecranon fractures in adults, we retrospectively compared functional outcomes, complications, and costs in 2 cohorts of displaced transverse olecranon fractures. These cohorts (10 patients each) were matched on age and length of follow-up. There were no significant differences between the groups in range of motion, functional scores, or arthrosis. There were no infections or nonunions in either group. There was no significant difference in rate of implant removal or symptomatic implants, though a trend was found toward a higher rate of both with tension bands. Operative time was significantly (P = .025) less for tension-band than locking-plate fixation (55 vs 85 minutes). In the tension-band group, charges were significantly less for implant, index procedure, and overall operative charges including reoperations ($6598.36 vs $14,333.46; P = .001). If all tension bands and no locking plates had been removed, tension-band fixation still would have cost significantly less ($7307.31 vs $14,160.26; P = .0005).

Operative intervention for geriatric hip fracture: does type of surgery affect hospital length of stay?

Hip fractures are the most costly fall-related fractures. Differences in hospital length of stay (LOS) based on type of surgery could have major financial implications in a potential bundled payment system in which all hip fractures are reimbursed a standard amount. We conducted a study to analyze differences in hospital LOS and costs for total hip arthroplasty (THA), hemiarthroplasty (HA), cephalomedullary nailing, open reduction and internal fixation (ORIF), and closed reduction and percutaneous pinning (CRPP). Through retrospective chart review, 615 patients over age 60 years across a 9-year period at an urban level I trauma center were identified. Mean LOS and costs for hip fracture repair were 6.91 days and $30,011.25, respectively. HA/THA was associated with the longest mean LOS (7.43 days) and highest costs ($33,657.90). After several patient factors were adjusted for, ORIF was associated with 0.84 fewer in-patient days and $3805.20 less in hospitalization costs compared with HA/THA (P=.042). CRPP was associated with 1.63 fewer days and $7383.90 less in costs than HA/THA (P=.0076). Our results provide insight into the financial implications of hip fracture fixation and identify targets for quality improvement initiatives to improve efficiency of resource utilization.

Low-intensity pulsed ultrasound (LIPUS) can decrease the economic burden of fracture non-union

OBJECTIVES

Few studies have evaluated the economic burden of surgical and conservative treatment of fracture non-union. An analysis was undertaken of aggregated payer data to determine economic costs of non-unions treated with surgery only vs non-unions treated conservatively with low-intensity pulsed ultrasound (LIPUS) only.

METHODS

This study used administrative claims from a health plan database including nearly 80 million people. Patients with a claim for non-union surgery or LIPUS for non-union were identified, from April 2007 until April 2010. A retrospective cohort was formed by pairwise demographic matching among patients who received 'Surgery Only' or 'LIPUS Only'. Date of the first non-union intervention (surgery or LIPUS) was defined as the index date. All medical costs were assessed over 12 months following the index date for the 'Surgery Only' and 'LIPUS Only' cohorts.

RESULTS

A total of 1158 matched patients were identified. 'Surgery Only' patients used significantly more healthcare services. In the year following intervention, 'Surgery Only' patients had total medical costs $6289 higher than 'LIPUS Only' patients (Mean = $11,276 vs $4986; p < 0.0001). Outpatient costs accounted for >68% of overall costs in both cohorts, and outpatient costs were significantly higher among the 'Surgery Only' cohort (Mean = $7682 vs $4196; p < 0.0001). Total inpatient costs were also significantly higher among the 'Surgery Only' cohort (Mean = $3302 vs $381; p < 0.0001).

LIMITATIONS

Limitations of this work are typical of all studies based on administrative claims data: errors in the database are assumed to distribute randomly between cohorts, and some patients may have been miscoded as to treatment received or costs billed.

CONCLUSIONS

'Surgery Only' patients used significantly and substantially more healthcare services in treatment of fracture non-union. Conservative treatment with 'LIPUS only' for fracture non-union could potentially result in cost savings projected to roughly $1 billion dollars [corrected].

Outcomes and cost of care for patients with distal radius fractures

This study was designed to evaluate treatment patterns in open treatment and percutaneous fixation of distal radius fractures, compare morbidity rates for the 2 types of treatment, and compare costs associated with the procedure and treatment of complications up to 1 year after surgery. From a 5% sample of nationwide Medicare claims records (1997-2009), patients with distal radius fractures were identified with International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM), codes. Patients who underwent percutaneous fixation and open treatment were tracked with appropriate Current Procedural Terminology codes. Complications were identified at 3 and 12 months. Medicare charges and payments associated with the treatment groups were compiled from the claims data. The rate of surgical treatment increased from 44.7 to 82.0 surgeries per 100,000 persons (+83.0%) over the study period. A total of 9343 procedures met the inclusion criteria between 1998 and 2008. The proportion of open treatment procedures increased from 25.5% in 1998 to 73.4% in 2008. Percutaneous fixation was associated with lower adjusted risk of carpal tunnel syndrome and release and mononeuritis at 3 and 12 months. The percutaneous fixation group had lower adjusted risk of malunion/nonunion at 3 months and tendon rupture at 12 months. Average charges were lower in the percutaneous fixation group for the index operation as well as for treatment of morbidities at 3 and 12 months. The operative fixation rate for distal radius fractures in the Medicare population continues to rise, with a significant trend toward open fixation. Charges and payments associated with open treatment are significantly higher than those for percutaneous fixation.

Value of information: interim analysis of a randomized, controlled trial of goal-directed hemodynamic treatment for aged patients

BACKGROUND

A randomized, controlled trial, intended to include 460 patients, is currently studying peroperative goal-directed hemodynamic treatment (GDHT) of aged hip-fracture patients. Interim efficacy analysis performed on the first 100 patients was statistically uncertain; thus, the trial is continuing in accordance with the trial protocol. This raised the present investigation's main question: Is it reasonable to continue to fund the trial to decrease uncertainty? To answer this question, a previously developed probabilistic cost-effectiveness model was used. That model depicts (1) a choice between routine fluid treatment and GDHT, given uncertainty of current evidence and (2) the monetary value of further data collection to decrease uncertainty. This monetary value, that is, the expected value of perfect information (EVPI), could be used to compare future research costs. Thus, the primary aim of the present investigation was to analyze EVPI of an ongoing trial with interim efficacy observed.

METHODS

A previously developed probabilistic decision analytic cost-effectiveness model was employed to compare the routine fluid treatment to GDHT. Results from the interim analysis, published trials, the meta-analysis, and the registry data were used as model inputs. EVPI was predicted using (1) combined uncertainty of model inputs; (2) threshold value of society's willingness to pay for one, quality-adjusted life-year; and (3) estimated number of future patients exposed to choice between GDHT and routine fluid treatment during the expected lifetime of GDHT.

RESULTS

If a decision to use GDHT were based on cost-effectiveness, then the decision would have a substantial degree of uncertainty. Assuming a 5-year lifetime of GDHT in clinical practice, the number of patients who would be subject to future decisions was 30,400. EVPI per patient would be €204 at a €20,000 threshold value of society's willingness to pay for one quality-adjusted life-year. Given a future population of 30,400 individuals, total EVPI would be €6.19 million.

CONCLUSIONS

If future trial costs are below EVPI, further data collection is potentially cost-effective. When applying a cost-effectiveness model, statements such as 'further research is needed' are replaced with 'further research is cost-effective and 'further funding of a trial is justified'.

Osteoporotic hip fractures: the burden of fixation failure

Osteoporotic hip fractures are a major cause of morbidity and mortality in the elderly. Furthermore, reduced implant anchorage in osteoporotic bone predisposes towards fixation failure and with an ageing population, even low failure rates represent a significant challenge to healthcare systems. Fixation failure in fragility fractures of the hip ranges from 5% in peritrochanteric fractures through to 15% and 41% in undisplaced and displaced fractures of the femoral neck, respectively. Our findings, in general, support the view that failed internal fixation of these fragility fractures carries a poor prognosis: it leads to a twofold increase in the length of hospital stay and a doubling of healthcare costs. Patients are more likely to suffer a downgrade in their residential status upon discharge with a consequent increase in social dependency. Furthermore, the marked disability and reduction in quality of life evident before salvage procedures may persist at long-term followup. The risk, of course, for the elderly patient with a prolonged period of decreased functioning is that the disability becomes permanent. Despite this, however, no clear link between revision surgery and an increase in mortality has been demonstrated in the literature.

Closed midshaft femur fractures: are they only for trauma centers?

Trauma centers are limited resources, particularly in rural areas, and availability of emergency care in some parts of the United States may be inadequate. The declining number of orthopedic surgeons willing to care for injured patients has limited access to fracture repair in some communities. We studied the management of closed midshaft femur fractures in both trauma centers (TCs) and nontrauma centers (NTCs) to evaluate outcome for this common orthopedic injury and determine if these issues have affected fracture care in Kentucky. All patients 16-years-old and older who suffered femur fractures in Kentucky from 2004 and 2005 were identified. There were 334 TC patients and 341 NTC patients with closed, midshaft femur fractures. The mean age of TC patients (33 ± 17 years) was significantly lower than that of NTC patients (59 ± 25 years). TC patients were more likely men (71% vs 44%), had more associated injuries (2.4 ± 2.1 vs 0.5 ± 1.2), and had longer lengths of stay (8.3 ± 9.8 vs 6.4 ± 7.1 days) (TCs vs NTCs, all P < 0.005). Although both groups ultimately underwent internal fixation (97% vs 99%, TCs vs NTCs), TC patients were more likely (2.7% vs 0.3%) to receive external fixation than the NTC patients (P < 0.05). There was no significant difference in the percentage of patients that received only a closed reduction. There was no significant difference in hospital mortality (0.3% vs 0.9%, TCs vs NTCs, P = 0.62). Although differences in patient populations exist between TCs and NTCs, both TCs and NTCs manage substantial numbers of patients with closed, midshaft femur fractures with low mortality in this state database.

A cost analysis of three methods of treating femoral shaft fractures in childrenA comparison of traction in hospital, traction in hospital/home and external fixation

INTRODUCTION

There is no consensus as to which is best treatment of femoral fractures in children.

PATIENTS AND METHODS

We performed a cost analysis comparing three treatments of femoral shaft fractures in children aged 3-15 years at 3 hospitals during the same period (1993-2000). The analysis included total medical costs and costs for the care provider and were calculated from the time of injury up to 1 year.

RESULTS

At hospital 1, treatment consisted of external fixation and early mobilization. At hospital 2, the treatment was skin or skeletal traction in hospital for 1-2 weeks, followed by home traction. At hospital 3, treatment was skin or skeletal traction in hospital until the fracture healed.

RESULTS

The average total costs per patient were EUR 10,000 at hospital 1, EUR 23,000 at hospital 2, and EUR 38,000 at hospital 3.

INTERPRETATION

The main factor for determining the cost of treatment was the number of days in hospital, which was lower in children treated with external fixation.

The impact of trauma in an urban pediatric orthopaedic practice

BACKGROUND

National data documenting the impact of pediatric trauma in general and of pediatric orthopaedic trauma in particular on the rates of hospital admissions and emergency-room visits have been reported. This study documents the frequency of and work involved in the care of pediatric orthopaedic trauma by a single urban pediatric orthopaedic group practice.

METHODS

The computerized billing records of a single practice group of 3.4 full-time-equivalent, fellowship-trained pediatric orthopaedic surgeons practicing in a freestanding pediatric hospital with a level-I trauma center were analyzed for one year (from July 2004 through June 2005). Every office visit and operative procedure was specifically sorted to determine the component of trauma care in the group's pediatric orthopaedic practice. Descriptive statistics, including the actual numbers and percentages of office fracture visits and operations for fracture care as well as the actual numbers and percentages of work relative value units generated by the physicians, are presented.

RESULTS

The practice generated 36,771 work relative value units, with 18,693 units (51%) from treatment provided in the operating room and 18,078 units (49%) from treatment provided in the office. A total of 1903 new fractures was seen and accounted for 5698 work relative value units (32% of all work relative value units for treatment provided in the office). The four fractures that were most frequently seen in the office were in the distal aspect of the radius (23%), forearm (14%), tibia (13%), and elbow (10%). Of the 18,693 work relative value units generated in the operating room, 5975 (32%) were from fracture care, representing the largest single category of work done in the operating room. Trauma-related operations were most commonly done for fractures of the elbow (25.3%), tibia (12%), femur (9.8%), forearm (5.5%), and the distal aspect of the radius (5%). Technically demanding fixation techniques, which are commonly used to treat fractures in adults, were frequently used, particularly for femoral and tibial fractures.

CONCLUSIONS AND CLINICAL RELEVANCE

This study documents the frequency and work relative value of the care of musculoskeletal injuries in an urban pediatric orthopaedic practice in the outpatient and inpatient settings. It is a snapshot in time of current trends in pediatric orthopaedic practice, but these data may have implications for future resource allocation of the pediatric orthopaedic manpower in North America.

Cost benefit with early operative fixation of unstable ankle fractures

INTRODUCTION

Ankle fractures are common and many require surgical intervention. It has been well documented that a delay in fracture fixation results in increased length of hospital stay and increased complication rate. Initial delay can also allow swelling or blistering to develop which may necessitate a further delay in operative fixation for up to 1 week. The aim of the current study was to review the length of hospital in-patient stay for operative ankle fractures over the previous 12-month period at our hospital and compare this to the length of hospital stay following the introduction of a fast-track system for the fixation of these fractures (all fractures fixed within 48 h).

PATIENTS AND METHODS

A retrospective review of all ankle fractures managed by open reduction and internal fixation over a 12-month period was undertaken. A protocol was then agreed to openly reduce and fix these fractures at the earliest possible opportunity over the next 6-month period. We then collected the data on all ankle fractures that needed open reduction and internal fixation over this 6-month period. The pre-protocol and post-protocol groups were then compared for total hospital length of stay and complication rate.

RESULTS

In the 12-month retrospective review, there were 83 ankle fractures that required surgical intervention. Sixty-two of these had surgery within 48 h (mean length of stay, 5.4 days), and 21 had surgery after 48 h (mean length of stay, 9.5 days). There were 39 ankle fractures in the post-protocol group who all had surgery within 48 h (mean length of stay, 5 days). There was no increase in complication rate after implementation of the fast-track system.

CONCLUSIONS

This study shows that early operative intervention for ankle fractures reduces the length of hospital stay. Intensive physiotherapy and co-ordinated discharge planning are also essential ingredients for early discharge. Early operative fixation for unstable ankle fractures has substantial cost-saving implications with no increase in complication rate.

Cost analysis of managing paediatric femoral shaft fractures: flexible intramedullary nailing versus non-operative management

This retrospective study aimed at comparing the cost of operative treatment versus non-operative treatment in the management of isolated paediatric femoral shaft fracture, in a single Trauma and Orthopaedic unit in a district general hospital in South East England. Patients were divided into three groups according to their treatment, and the cost was analysed depending on their requirements for hospital stay, theatre, physiotherapy, radiographs and plaster cast. Sixty-two children were admitted to our trauma unit with an isolated femoral shaft fracture from January 2001 to April 2005. There is a significant variation in the cost between the 16 patients treated with operative flexible nailing in comparison with those treated non-operatively either by traction alone (31 patients), or by traction followed by cast (15 patients). Operative treatment was shown to reduce the inpatient stay by approximately 75% (mean of 9.8 days in the operative group in comparison to 39.3 days in the non-operative group). It has also reduced the overall cost for treatment by more than 60% in comparison to traction alone and by almost 30% in comparison to using traction followed by casting.

Damage control orthopedics in patients with multiple injuries is effective, time saving, and safe

BACKGROUND

Although early fracture fixation is expedient in patients with multiple injuries, early total care (ETC) may be associated with posttraumatic systemic complications. This study was conducted to prospectively evaluate the concept of damage control by immediate external fracture fixation (damage control orthopedics [DCO]) and consecutive conversion osteosynthesis with regard to time savings, effectiveness, and safety.

METHODS

In a prospective controlled trial, a cohort of 1,070 patients with an Injury Severity Score (ISS) of 20.7 were admitted to a Level I trauma center over a 3.5-year period. Patients with an ISS > 15, survival of more than 24 hours, and without interhospital transfer were included. In all patients with major fractures requiring immediate stabilization, external fixation was performed (DCO). Conversion was executed at the earliest possible time as a one-stage procedure after stabilization of organ functions. TRISS was calculated for patients requiring DCO (DCO group) and for patients without major fractures (control group). Time spent on particular and all surgical procedures, blood loss, and complications of DCO were compared with data of consecutive conversion osteosyntheses which were considered as hypothetical ETC procedures (h-ETC) in identical patients.

RESULTS

Four hundred nine patients fulfilled the inclusion criteria. Seventy-five (ISS of 37.3) required DCO for 135 fractures, whereas 334 patients (ISS of 30.4) did not require immediate fracture fixation. Mean surgical time was 62 +/- 30 minutes (SEM, 3.5) for DCO. Because of fracture consolidation with external fixation (n = 3) and injury-related death (n = 15), conversion (h-ETC) was performed in 57 patients for 101 fractures. Duration of external fixation averaged 13.7 days (range, 3-46 days). Fifty-five patients (96.5%) required intensive care treatment and 42 patients (73.7%) required mechanical ventilation at the time of conversion. Mean operation time for conversion was 233 +/- 19 minutes (SEM, 18.7) with a value of p < 0.001. Also, blood loss was significantly (p < 0.001) different for DCO (<50 mL) and h-ETC (472 mL; SEM, 63). Pin-track infections were identified in five patients, two patients with acetabular plate osteosynthesis had deep wound infection, and one patient died related to bacterial sepsis with infections of all wound sites. Overall mortality in DCO patients was significantly lower than predicted by TRISS (20% vs. 39.3%), as it was in the 334 patients without immediate fracture fixation (29.5% vs. 24.3%).

CONCLUSION

DCO appears to provide a major reduction of operation time and blood loss in the primary treatment period in severely injured patients compared with h-ETC. In addition, we found that DCO is not associated with an increased rate of procedure-related complications. So far, DCO with early and one-stage conversion seems to be a safe strategy of primary fracture treatment in patients with multiple injuries.

Cast immobilization versus percutaneous pin fixation of displaced distal radius fractures in children: a prospective, randomized study

Thirty-four patients were enrolled in a prospective randomized study comparing cast immobilization alone versus percutaneous pin fixation following closed reduction of distal radial metaphyseal fractures. Patients older than 10 years of age with greater than 30 degrees of dorsal angulation or with complete fracture displacement were eligible for enrollment. Average follow-up was 10.5 weeks. All fractures healed uneventfully without deformity, growth arrest, or functional limitations. Overall complication rates were similar between groups. Thirty-nine percent of patients treated with casting had subsequent loss of reduction requiring remanipulation; there were no cases of loss of reduction in patients treated with pin fixation. Thirty-eight percent of patients treated with pin fixation had pin-related complications; all resolved following pin removal without long-term sequelae. Cost analysis showed no significant difference in treatment charges between groups. Treating surgeons should be aware of the potential short-term complications of each treatment method and adjust their postoperative care appropriately.

An economic analysis of management strategies for closed and open grade I tibial shaft fractures

BACKGROUND

Closed and open grade I (low-energy) tibial shaft fractures are a common and costly event, and the optimal management for such injuries remains uncertain.

METHODS

We explored costs associated with treatment of low-energy tibial fractures with either casting, casting with therapeutic ultrasound, or intramedullary nailing (with and without reaming) by use of a decision tree.

RESULTS

From a governmental perspective, the mean associated costs were USD 3,400 for operative management by reamed intramedullary nailing, USD 5,000 for operative management by non-reamed intramedullary nailing, USD 5,000 for casting, and USD 5,300 for casting with therapeutic ultrasound. With respect to the financial burden to society, the mean associated costs were USD 12,500 for reamed intramedullary nailing, USD 13,300 for casting with therapeutic ultrasound, USD 15,600 for operative management by non-reamed intramedullary nailing, and USD 17,300 for casting alone.

INTERPRETATION

Our analysis suggests that, from an economic standpoint, reamed intramedullary nailing is the treatment of choice for closed and open grade I tibial shaft fractures. Considering financial burden to society, there is preliminary evidence that treatment of low-energy tibial fractures with therapeutic ultrasound and casting may also be an economically sound intervention.

Direct medical costs of traumatic thoracolumbar spine fractures

BACKGROUND

The costs and cost-effectiveness of treatment of thoracolumbar fractures are poorly known.

METHODS

We estimated the costs of hospital care and outpatient visits for patients with traumatic thoracolumbar spine fractures.

RESULTS

Stable fractures without neurological deficits were treated nonoperatively and the costs were EUR 5,100. Unstable fractures without neurological deficits were treated either nonoperatively, with an average of 29 hospitalization days and average cost of EUR 12,500 (86% of which represented hospitalization costs), or operatively with 24 hospitalization days and average cost of EUR 19,700 (48% of which represented hospitalization costs and 42% surgery costs). Unstable fractures with neurological deficits were usually operated (average costs EUR 31,900).

INTERPRETATION

For all patients, the costs of hospitalization days were the main cost driver. Although the length of stay for patients with unstable fractures and without neurological deficit who were treated operatively was shorter than for patients treated nonoperatively, the total costs were higher due to the additional costs of surgery. Surgical treatment must therefore be shown to give a better outcome in order to outweigh the costs. Future research should focus on the cost-effectiveness of operative and nonoperative treatment of patients with unstable vertebral fractures who have no neurological deficits, and take indirect costs and quality of life into account.

Cost-Effective Management of Isolated Facial Fractures

The purpose of this study was to evaluate the subset of costs incurred for surgical treatment of isolated midface and mandible fractures of patients admitted directly from the emergency department compared with those admitted as outpatients after evaluation and discharge from the emergency department. After institutional review board approval, the records of patients admitted to Wake Forest University Baptist Medical Center were studied retrospectively for patients who underwent surgical repair of an isolated facial fracture between July 1, 1999 and June 30, 2000. Patients were placed into one of two groups: admission from the emergency department versus admission as an out-patient. Total hospital charges were compared, and complications were evaluated. Mechanism of injury, age, and gender were recorded within each group. Forty-two patients met the study criteria. Twenty-eight patients were admitted directly from the emergency department (Group A), and 14 were admitted as outpatients after elective scheduling for operative repair (Group B). Operative charges based on utilization of time and materials showed no statistical significance between Group A (P = 0.275) and Group B (P = 0.393). Patients admitted directly from the emergency department had a mean hospital charge of 3,556.66 dollars higher (P< or = 0.001) and stayed 2 days longer in the hospital as compared with the outpatient group. No differences were noted in complications between the study groups. The results of this study reveal a significant decrease in cost for patients with isolated facial fractures admitted as outpatients on scheduling surgery as compared with immediate admission from the emergency department.

A prospective cost analysis following operative treatment of unstable ankle fractures: 30 patients followed for 1 year

BACKGROUND

Ankle fractures remain one of the commonest injuries requiring operation. Quality of life and the overall costs associated with the treatment of such injuries are rarely reported. We did a pilot study to determine the cost of treating patients operatively with unstable ankle fractures and to measure the patients' quality of life (utility scores) over time.

PATIENTS AND METHODS

30 patients (17 men) were eligible and included in the study. They were on the average 52 (18-81) years old. All patients had type B Weber fractures (OTA 44B).

RESULTS

The mean utility score from the Health Utilities Index immediately after surgery was 0.4. At 12 months follow-up, this score had increased to 0.78. The cost was, on average, USD 2,143 per patient.

INTERPRETATION

Our findings indicate that patients operated on for ankle fractures had significant gains in health at an acceptable cost. These results provide data for studies of larger sample size.

A retrospective analysis of health care costs for bone fractures in women with early-stage breast carcinoma

BACKGROUND

In this retrospective data base study, the authors sought to estimate direct costs for bone fractures in women age > or =65 years with early-stage breast carcinoma and to compare those costs with treatment costs for bone fractures in older women without early-stage breast carcinoma.

METHODS

Direct costs for bone fractures in patients with early-stage breast carcinoma, which consist of excess treatment costs for bone fracture and excess costs of long-term care for bone fracture, were evaluated by using the 1997-1998 Standard Analytical File. The statistical significance of the difference in inpatient costs, medical treatment costs, and long-term care admission rates were determined with the t test and the Fisher chi-square test, respectively.

RESULTS

For older women with early-stage breast carcinoma, the direct costs for bone fracture were estimated at $45,579, and 57% of those costs came from treating the bone fracture (32% came from inpatient hospital costs, and 25% came from noninpatient hospital costs), 25% came from other excess treatment costs, and 18% came from excess long-term care costs. The women who had early-stage breast carcinoma and sustained bone fracture did not differ significantly from the women without early-stage breast carcinoma who sustained a bone fracture.

CONCLUSIONS

Bone fracture was associated with high direct costs in older women with early-stage breast carcinoma. Additional research should include appropriate, incidence-based studies to investigate the potential benefit of an intervention for preventing bone fracture in this increasingly large patient population.

Cost-based analysis of the treatment of mandibular fractures in a tertiary care center

BACKGROUND

The objective of this study was to assess the cost effectiveness of alternative treatment algorithms for the management of isolated mandibular fractures.

METHODS

This is an institutional review board-approved retrospective study consisting of a chart review of 25 patients who underwent operative repair of an isolated mandible fracture between July 1, 1999, and June 30, 2000. Patients were stratified into two groups: patients who were immediately admitted to the hospital from the emergency department (ED) versus patients who were discharged from the ED and who returned for elective scheduled operative repair. Patients' total hospital charges were compared on the basis of operating room (OR) time, operative materials, and hospital charges.

RESULTS

Seventeen of the study patients were directly admitted from the ED, and eight underwent elective scheduled operative repair. Of the patients directly admitted from the ED, the mean age was 34.9 years (range, 19-57 years), and the study population consisted of 16 men and 1 woman. This group had a mean OR time of 161 minutes, a mean OR time charge of $1,978.66, a mean OR supply charge of 1,049.43 US dollars, a mean hospital floor charge of 5,041.02 US dollars, and an average hospital stay of 2.82 days. The treatment group of patients undergoing scheduled operative repair (n = 8) had a mean age of 30.3 years (range, 19-49 years), and all were men. This second treatment group had a mean OR time of 167.1 minutes, a mean OR time charge of 2,162.03 US dollars, a mean OR supply charge of 871.00 US dollars, a mean hospital floor charge of 2,759.38 US dollars, and a mean hospital stay of 0.88 days. Comparison of the two study groups demonstrated operative charges were made on the basis of time and materials and were shown to have no statistically significant difference (p = 0.753 and p = 0.289, respectively). Comparison of hospital charges revealed that patients admitted directly from the ED had a mean charge 2,276.70 US dollars higher (p = 0.019) and stayed 1.95 days longer in the hospital than patients discharged from the emergency department who returned for elective scheduled repair. There were two complications in the study patients; both occurred in the group admitted directly from the emergency room.

CONCLUSION

The results of this study indicate that the most cost-effective management of an isolated mandibular fracture is initial evaluation in the ED with elective interval operative repair. This management protocol is, of course, only applicable if the patient is clinically stable and has no other injuries or comorbidities necessitating in-hospital observation.

Operative compared with nonoperative treatment of a thoracolumbar burst fracture without neurological deficit. A prospective, randomized study

BACKGROUND

To our knowledge, a prospective, randomized study comparing operative and nonoperative treatment of a thoracolumbar burst fracture in patients without a neurological deficit has never been performed. Our hypothesis was that operative treatment would lead to superior long-term clinical outcomes.

METHODS

From 1994 to 1998, forty-seven consecutive patients (thirty-two men and fifteen women) with a stable thoracolumbar burst fracture and no neurological deficit were randomized to one of two treatment groups: operative (posterior or anterior arthrodesis and instrumentation) or nonoperative treatment (application of a body cast or orthosis). Radiographs and computed tomography scans were analyzed for sagittal alignment and canal compromise. All patients completed a questionnaire to assess any disability they may have had before the injury, and they indicated the degree of pain at the time of presentation with use of a visual analog scale. The average duration of follow-up was forty-four months (minimum, twenty-four months). After treatment, patients indicated the degree of pain with use of the visual analog scale and they completed the Roland and Morris disability questionnaire, the Oswestry back-pain questionnaire, and the Short Form-36 (SF-36) health survey.

RESULTS

In the operative group (twenty-four patients), the average fracture kyphosis was 10.1 degrees at the time of admission and 13 degrees at the final follow-up evaluation. The average canal compromise was 39% on admission, and it improved to 22% at the final follow-up examination. In the nonoperative group (twenty-three patients), the average kyphosis was 11.3 degrees at the time of admission and 13.8 degrees at the final follow-up examination after treatment. The average canal compromise was 34% at the time of admission and improved to 19% at the final follow-up examination. On the basis of the numbers available, no significant difference was found between the two groups with respect to return to work. The average pain scores at the time of the latest follow-up were similar for both groups. The preinjury scores were similar for both groups; however, at the time of the final follow-up, those who were treated nonoperatively reported less disability. Final scores on the SF-36 and Oswestry questionnaires were similar for the two groups, although certain trends favored those treated without surgery. Complications were more frequent in the operative group.

CONCLUSION

We found that operative treatment of patients with a stable thoracolumbar burst fracture and normal findings on the neurological examination provided no major long-term advantage compared with nonoperative treatment.

Reduction versus remodeling in pediatric distal forearm fractures: a preliminary cost analysis

The inherent ability of pediatric metaphyseal radius fractures to heal and remodel made us question the need for immediate anatomic reduction under conscious sedation. We believe that isolated closed distal radius fractures with 15 degrees of angulation and 1 cm of shortening will heal well and remodel completely without clinical or functional sequelae. Time and expense can be decreased by splinting and follow-up without the need for immediate anatomic reduction in the emergency room. In order to answer this question, we retrospectively evaluated 34 pediatric metaphyseal wrist fractures that lost position after attempted reduction and healed in their angulated or shortened position. We looked at the time to healing, time to remodeling and any residual clinical or functional deficits. We then did a comparison cost analysis with time matched patients who had complete but minimally displaced fractures of the distal radius that were treated by immediate splinting with orthopaedic follow-up. Our results showed that skeletally immature patients with open physes, isolated injuries, dorsovolar and radioulnar angulations less than 15 degrees and less than 1 cm of shortening will heal and be out of cast within an average of 6 weeks and completely remodel within an average of 7.5 months. The average time in the emergency room was 2 h less with no reduction. The cost of the emergency room visit with attempted reduction was 50% more than splinting with early referral (US dollars 536 versus US dollars 270). None of our patients had significant clinical deformities or residual functional deficits.

Comparison between closed reduction with percutaneous pinning and open reduction with pinning in children with closed totally displaced supracondylar humeral fractures: a randomized controlled trial

This was a randomized controlled trial of 28 children 1 year to 12 years of age with closed totally displaced supracondylar humeral fracture. The purpose of the study was to compare closed reduction and pinning (group A) and open reduction and pinning (group B). Each group consisted of 14 children. The general characteristics of both groups (age, sex side, displacement, nerve injury preoperatively) were statistically the same (P > 0.05). All cases healed with good alignment without cubitus varus, without infection and with a good range of motion except for one. The mean +/- standard deviation of the Baumann's angle difference between the injured and uninjured side were 2.32 +/- 1.6 degrees in group A (range, 0-6.5 degrees) and 2.45 +/- 1.8 degrees in group B (range, 0-6.5 degrees). This difference was statistically not significant (P = 0.8). By Flynn criteria, group A had good to excellent results in 100%, and group B had good to excellent results in 93% and fair in 7%. This difference was not statistically significant (P = 1). The satisfaction score (0-10) was significantly higher in group A for both parents' and evaluator's (blinded to treatment) perspective (P = 0.017 and 0.019, respectively). The author concludes that both treatments gave good results. Closed reduction should be performed first and, if it fails, then open reduction can be performed. This will produce good results in the hands of an experienced surgeon.

[Economic aspect of osteoporotic fracture treatment]

The authors analyzed 307 cases of osteoporotic fractures of proximal femur, distal radius and vertebral bodies treated in the Department of Orthopedics and Traumatology in Siedlce in 1997. The majority (243) of the fractures referred to the proximal femur. They were treated operatively (202) by Ender intramedullary nailing, hemialloplastics or fixation with hip screws. There were 40 patients hospitalized with the distal radius fracture, 29 of them were operated. The fractures of the vertebral bodies (24) were stabilized with Jewett brace or plaster jacket. When analyzing costs of hospital treatment of osteoporotic fractures, the authors considered the number of patients, the period of hospital stay and the number and type of surgeries. Higher costs of the therapy of osteoporotic fractures in comparison with the treatment of other cases in the orthopedic-traumatic ward were proven.

A financial analysis of maxillomandibular fixation versus rigid internal fixation for treatment of mandibular fractures

PURPOSE

The aim of this study was to compare the cost-effectiveness of mandibular fracture treatment by closed reduction with maxillomandibular fixation (CRF) with open reduction and rigid internal fixation (ORIF).

PATIENTS AND METHODS

This was a retrospective study of 85 patients admitted to the Oral and Maxillofacial Surgery Service at San Francisco General Hospital and treated for mandibular fractures from January 1 to December 31, 1993. The patients were divided into 2 groups: 1) those treated with CRF and 2) those treated with ORIF. The outcome variables were length of hospital stay, duration of anesthesia, and time in operating room. The charge for primary fracture treatment included the fees for the operation and hospitalization without any complications. Within the group of 85 patients treated for mandibular fractures in 1993, 10 patients treated with CRF and 10 patients treated with ORIF were randomly selected, and hospital billing statements were used to estimate the average charge of primary treatment. The average charge to manage a major postoperative infection also was estimated based on the billing statements of 10 randomly selected patients treated in 1992 (5 treated with CRF, 5 with ORIF) who required hospital admission for the management of a complication. The average total charge was computed by using the average charge for primary treatment plus the incidence of postoperative infection multiplied by the average charge for management of that complication.

RESULTS

Eighty-five patients were included in the study. The average charge for primary treatment was $10,100 for the CRF group and $28,362 for the ORIF group. The average charge for the inpatient management of a major postoperative infection was $26,671 for the CRF group and $39,213 for the ORIF group. The average total charge for management of a mandible fracture with CRF was $10,927; the total charge for the ORIF group was $34,636.

CONCLUSION

The results of this retrospective study suggest that the use of CRF in the management of mandibular fractures at our institution provides considerable savings over treatment by using ORIF. The use of ORIF should be reserved for patients and fracture types with specific indications.

Intermaxillary fixation is not usually necessary to reduce mandibular fractures

We undertook a retrospective study of all isolated mandibular fractures which had required active management over a 1-year period at the Maxillofacial Unit at Newcastle General Hospital. Patients with single or multiple fractures of the mandible were included in the study, if there were other simultaneous fractures of the facial skeleton, those patients were excluded. All case notes and radiographs were reviewed by a single operator. A total of 202 cases of fractured mandible were identified of which 115 fulfilled the selection criteria of: isolated fracture, no previous facial fracture, treatment by open reduction and internal fixation using titanium osteosynthesis miniplates, and all case notes and radiographs available to study. Sixty-six patients had their fractures reduced manually to obtain anatomical reduction without the use of peroperative intermaxillary fixation (IMF). Forty-nine were treated conventionally using peroperative IMF. The two groups were broadly similar in severity and type of fracture, and the method of reduction seemed to be decided by the operator according to their preference. IMF was not used routinely postoperatively. Overall there were significantly fewer occlusal discrepancies in the early postoperative period in those patients treated by anatomical reduction (6/66 compared with 16/49, P = 0.002) but there was no difference in the final outcome of the occlusion between the two methods of reduction. Avoidance of the use of peroperative IMF is more economical in time and cost, is safer for the operator, and more comfortable for the patient. As this technique produces comparable results in the long term with fewer early complications, we conclude that IMF is not usually necessary to reduce fractures confined to the mandibular bone.

Skeletal traction versus external fixation for pediatric femoral shaft fractures: a comparison of hospital costs and charges

OBJECTIVES

To compare the hospital costs, charges, and reimbursement for treatment of pediatric femur fractures by two treatment methods: external fixation and 90-90 traction with spica casting.

DESIGN

Retrospective clinical review.

SETTING

Department of Orthopaedic Surgery, Children's Hospital Oakland, regional pediatric trauma center.

PATIENTS

Twenty-nine consecutive patients between the ages of five and ten with a fracture of the femoral shaft were treated by one of two methods: external fixation (sixteen patients) or 90-90 skeletal traction followed by spica casting (thirteen patients).

INTERVENTION

External fixation or 90-90 traction followed by spica casting.

MAIN OUTCOME MEASURE

Hospital billing data including costs, charges, reimbursement for the initial inpatient hospitalization, and outpatient financial data until fracture union and cessation of treatment.

RESULTS

There was no difference in age, total treatment time, mechanism of injury, or number of associated injuries between the two groups. The average charge for treatment with skeletal traction and spica casting was $32,094 per patient versus $21,439 for external fixation (p < 0.001). The average cost for treatment with traction and spica casting was $22,396 per patient versus $11,520 for external fixation (p < 0.001); reimbursement was $30,846 and $7,490, respectively (p < 0.001). The number of days in the hospital was larger for the traction group than for the external fixation group (22.3 days versus 4.7 days, p < 0.0001).

CONCLUSIONS

External fixation of pediatric femoral shaft fractures results in decreased hospital costs and length of hospitalization, but produces significantly less income for the hospital when compared with skeletal traction followed by spica casting.

Isolated ulnar shaft fractures treated with functional braces

OBJECTIVE

To report the results from functional bracing of isolated ulnar shaft fractures.

DESIGN

Retrospective review.

SETTING

Two university hospitals.

PATIENTS

Isolated ulnar shaft fractures in 444 patients were stabilized in functional braces that permitted full range of motion of all joints.

INTERVENTION

Prefabricated braces that extended from below the elbow to above the wrist were applied within the first week after the initial injury.

OUTCOME MEASURES

Union of the fracture, fracture angulation, and final range of motion of the forearm were evaluated.

RESULTS

Two hundred eighty-seven patients were available for follow-up (65 percent). Union took place in 99 percent of the fractures. Shortening of the ulna averaged 1.1 millimeters (range 0 to 10 millimeters). Final radial angulation averaged 5 degrees (range 0 to 18 degrees). Dorsal angulation averaged 5 degrees (range 0 to 20 degrees). Average loss of pronation was greatest in fractures of the proximal third of the ulna, averaging 12 degrees. Fractures in the distal third averaged a loss of 5 degrees of pronation.

CONCLUSIONS

Functional bracing is a viable therapeutic alternative in the management of isolated ulnar shaft fractures. It is associated with a 99 percent union rate and good to excellent functional results in more than 96 percent of patients.

Changes in charges and costs associated with hospitalization of patients with mandibular fractures between 1991 and 1993

PURPOSE

The purpose of the study was to examine the changes in costs, charges, and income related to hospitalization of patients with mandibular fractures treated over a 3-year period.

PATIENTS AND METHODS

The study involved retrospective analysis of data on 97 patients treated by the Department of Oral and Maxillofacial Surgery between 1991 and 1993. Biographical data were obtained from the Trauma Registry, and the financial data were obtained from the Financial Services Administration. The study examined the changes in costs and charges of hospitalization, insurance status, reimbursement, total revenue, and income losses from hospitalization of patients admitted with a primary diagnosis of mandibular fracture. In addition, the study examined the changes in costs of major items involved in treatment. Possible variables such as age, gender, and cause of fracture were also recorded.

RESULTS

Twenty-nine patients were admitted in 1991, 35 in 1992, and 33 in 1993. These patients were predominantly young males. The average cost of treatment decreased by 2% in 1992 and increased by 58% in 1993. The average charge increased by 12.9% in 1992 and by 76.8% in 1993. The total reimbursement increased by 11.2% in 1992 and by 47.7% in 1993. The average payment per patient to the institution by third-party payers decreased by 7.8% in 1992 and increased by 56.6% in 1993. The loss of income to the institution (cost minus reimbursement) increased by 105.9% in 1992 and by 58% in 1993. The average institution income loss from the care for each patient increased by 70.6% in 1992 and by 67.8% in 1993.

CONCLUSIONS

This study showed that there was a continued increase in costs, charges, and income loss for hospitalization of mandibular fracture patients during the years 1991 to 1993, whereas the reimbursement rate decreased from 65% to 47% of the charges. The increase in cost of supplies and use of rigid fixation, the increase in the number of uninsured patients, and the pricing practices of the institution were possible causes of these changes.

Isolated closed diaphyseal fractures of the femur in children: comparison of effectiveness and cost of several treatment methods

The effectiveness of several treatment modalities for isolated closed femur fractures in children ages 4 through 16 years is compared based on outcome (clinical results, morbidity, and parents' satisfaction) and cost. Between 1986 and 1993, 30 patients were treated. Treatment methods included immediate hip spica cast application, distal femoral skeletal traction pin to align the fracture followed by early hip spica cast incorporating the pin (6th day), in-hospital traction, primary external fixation, and primary intramedullary nailing. Average follow up was 4.1 years. Overall results were excellent with minimal morbidity for all treatment methods. Early application of hip spica cast with or without incorporation of the distal femoral traction pin required the fewest hospital days, the shortest time to union, and had the lowest overall cost. Complications, mainly malunion and femoral length discrepancy, however, were greater. Skeletal traction resulted in the longest hospital stay and was equal in cost to external fixation and intramedullary nailing. Primary external fixation appears most applicable in patients who are unlikely to tolerate early casting and who are at increased risk of avascular necrosis with femoral nailing. Patients treated with an intramedullary nail had the fewest complications. Age, size, and gender of patient, location and type of fracture, as well as social circumstances are all significant factors in choosing the optimal method of treatment.

Subtrochanteric fractures of the femur

A consecutive series of 103 patients with a subtrochanteric fracture were prospectively studied. Ten patients were treated non-operatively, whilst the other 93 had operative treatment. The overall fixation failure rate was 12 per cent with a re-operation rate of 6 per cent by 1 year. There were six (8 per cent) failures of fixation for the 74 fractures treated with the sliding hip screw. No method of fracture classification was demonstrated to be of value in predicting either the choice of treatment or the risk of fracture healing complications. Either intramedullary nailing or extramedullary fixation with a dynamic hip screw appear to give the best results for subtrochanteric fractures.
