Are Cardiac Complications Associated With Other Adverse Events? A Look at 56,000 Orthopaedic Trauma Patients.

The purpose of this study was to identify those complications for which patients with adverse cardiac events are at risk within the 30-day postoperative period following treatment oforthopaedic trauma cases. This was a retrospective cohort study of orthopaedic trauma patients in the United States between 2006 and 2013. A total of 56,336 patients meeting any one of 89 CPT codes in the American College of Surgeons National Surgical Quality Improvement Program database were used. The main outcome measure was myocardial infarction or cardiac arrest within the 30-day postoperative period. Patients experiencing adverse cardiac events were at a significantly higher risk to have also developed deep surgical site infection, pneumonia, the need for reintubation, pulmonary emboli, a failure to wean off of ventilation, chronic and acute renal failure, urinary tract infection, stroke, deep venous thrombosis, sepsis, and shock. Cardiac complications in orthopaedic trauma patients are relatively uncommon (1.3%); however, cardiac complications are associated with greater risks of other complications, including pneumonia, stroke, and urinary tract infection.

Management of Femoral Defects Greater Than 5 cm Following Open Femur Fractures: A 12-Year Retrospective Review.

This study sought to evaluate the outcomes of patients with osseous defects exceeding 5 cm following open femur fractures. Size of the osseous defect, method of internal fixation (plate vs. intramedullary nail), patient demographics, medical comorbidities, and surgical complications were collected. Twenty-seven of the 832 open femur fracture patients had osseous defects exceeding 5 cm. Mean osseous defect size was 8 cm, and each patient had an average of four operations including initial debridement. Average time from injury to bone grafting was 123.7 days. The overall complication rate was 48.1% (n = 13). The most common complications were infection (26.0%, n = 7) and nonunion (41.0%, n = 11). Smoking, diabetes, ASA score, and defect size did not independently increase the risk of a complication. Management of open femur fractures with osseous defects greater than 5 cm is associated with high complication rate, driven primarily by infection and nonunion.

Predicting the post-operative length of stay for the orthopaedic trauma patient.

PURPOSE: Length of stay (LOS) is a major driver of cost and quality of care. A bundled payment system makes it essential for orthopaedic surgeons to understand factors that increase a patient's LOS. Yet, minimal data regarding predictors of LOS currently exist. Using the ACS-NSQIP database, this is the first study to identify risk factors for increased LOS for orthopaedic trauma patients and create a personalized LOS calculator. METHODS: All orthopaedic trauma surgery between 2006 and 2013 were identified from the ACS-NSQIP database using CPT codes. Patient demographics, pre-operative comorbidities, anatomic location of injury, and post-operative in-hospital complications were collected. To control for individual patient comorbidities, a negative binomial regression model evaluated hospital LOS after surgery. Betas (ß), were determined for each pre-operative patient characteristic. We selected significant predictors of LOS (p < 0.05) using backwards stepwise elimination. RESULTS: 49,778 orthopaedic trauma patients were included in the analysis. Deep incisional surgical site infections and superficial surgical site infections were associated with the greatest percent change in predicted LOS (ß = 1.2760 and 1.2473, respectively; p < 0.0001 for both). A post-operative LOS risk calculator was developed based on the formula: [Formula: see text]. CONCLUSIONS: Utilizing a large prospective cohort of orthopaedic trauma patients, we created the first personalized LOS calculator based on pre-operative comorbidities, post-operative complications and location of surgery. Future work may assess the use of this calculator and attempt to validate its utility as an accurate model. To improve the quality measures of hospitals, orthopaedists must employ such predictive tools to optimize care and better manage resources.

Does Physician Reimbursement Correlate to Risk in Orthopaedic Trauma?

This study investigated whether current Medicare reimbursements for orthopaedic trauma procedures correlate with complications. A total of 18,510 patients representing 33 orthopaedic trauma procedures from 2005 to 2011 were studied. Adverse events and Medicare payments for each orthopaedic trauma procedure were collected. Linear regressions determined correlations between complications and Medicare payments for orthopaedic trauma procedures. A weak correlation between Medicare payments and complications was found for all procedures (r = .399, p = .021). A 1.0% increase in complications was associated with a payment increase of only $100. There were no correlations between complications and reimbursements for upper extremity (p = .878) and lower extremity (p = .713) procedures. A strong correlation (r = .808, p = .015) existed for hip and pelvic fractures, but a 1.1% increase in hip and pelvic complications correlated with only an increase of $100 in reimbursements. This study is the first to show that Medicare payments are not strongly correlated with complications, therefore demonstrating the potential risks of a bundled payment system for orthopaedic trauma surgeons.

Damage Control Plating in Open Tibial Shaft Fractures: A Cheaper and Equally Effective Alternative to Spanning External Fixation.

The purpose of this study was to evaluate damage control plating (DCP) as an alternative to external fixation (EF) in the provisional stabilization of open tibial shaft fractures. Through retrospective analysis, the study found 445 patients who underwent operative fixation for tibial shaft fractures from 2008 to 2012. Twenty patients received DCP or EF before intramedullary nailing with a minimum follow-up of 3 months. Charts and radiographs were reviewed for postoperative complications. Hospital charges were reviewed for implant costs. Nine patients (45%) with DCP and 11 patients (55%) with EF were analyzed. There was no significant difference in the complication rates. The mean implant cost of DCP was $1028, whereas mean EF construct cost was $4204. Therefore, DCP resulted in significant cost savings with no difference in complication rates, making it a valuable alternative to EF for the provisional stabilization of open tibial shaft fractures.

Open treatment of ankle fracture as inpatient increases risk of complication.

BACKGROUND: Ankle fracture is one of the most common injuries treated by orthopaedic surgeons, and its incidence is only expected to rise with an aging population. It is also associated with often costly complications, yet there is little literature on risk factors, especially modifiable ones, driving these complications. The aim of this study is to reveal whether inpatient treatment after ankle fracture is associated with higher incidence of postoperative complications. As the USA moves towards a bundled payment healthcare system, it is imperative that orthopaedists maximize patient outcome and quality of care while also reducing overall costs. MATERIALS AND METHODS: We used the American College of Surgeons National Surgical Quality Improvement Program database to compare complication rates between inpatient and outpatient treatment of ankle fracture. We collected patient demographics, comorbidities, and postoperative complications from both groups, then compared treatments using a multinomial logistic regression model. RESULTS: We identified 7383 patients, with 2630 (36%) in the outpatient and 2630 (36%) in the inpatient group. Of these, 104 (4.0%) inpatients compared with 52 (2.0%) outpatients developed a complication (p < 0.001). CONCLUSIONS: Inpatients developed major complications including deep wound infection and pulmonary embolism, as well as minor complications such as pneumonia and urinary tract infection, at significantly greater rates. As reimbursement models begin to incorporate value-based care, orthopaedic surgeons need to be aware of factors associated with increased incidence of postoperative complications. LEVEL OF EVIDENCE: Level III retrospective comparative study.

Incidence and predictive risk factors of postoperative sepsis in orthopedic trauma patients.

BACKGROUND: Postoperative sepsis is associated with high mortality and the national costs of septicemia exceed those of any other diagnosis. While numerous studies in the basic orthopedic science literature suggest that traumatic injuries facilitate the development of sepsis, it is currently unclear whether orthopedic trauma patients are at increased risk. The purpose of this study was thus to assess the incidence of sepsis and determine the risk factors that significantly predicted septicemia following orthopedic trauma surgery. MATERIALS AND METHODS: 56,336 orthopedic trauma patients treated between 2006 and 2013 were identified in the ACS-NSQIP database. Documentation of postoperative sepsis/septic shock, demographics, surgical variables, and preoperative comorbidities was collected. Chi-squared analyses were used to assess differences in the rates of sepsis between trauma and nontrauma groups. Binary multivariable regressions identified risk factors that significantly predicted the development of postoperative septicemia in orthopedic trauma patients. RESULTS: There was a significant difference in the overall rates of both sepsis and septic shock between orthopedic trauma (1.6%) and nontrauma (0.5%) patients (p < 0.001). For orthopedic trauma patients, ventilator use (OR = 15.1, p = 0.002), history of pain at rest (OR = 2.8, p = 0.036), and prior sepsis (OR = 2.6, p < 0.001) were significantly associated with septicemia. Statistically predictive, modifiable comorbidities included hypertension (OR = 2.1, p = 0.003) and the use of corticosteroids (OR = 2.1, p = 0.016). CONCLUSIONS: There is a significantly greater incidence of postoperative sepsis in the trauma cohort. Clinicians should be aware of these predictive characteristics, may seek to counsel at-risk patients, and should consider addressing modifiable risk factors such as hypertension and corticosteroid use preoperatively. Level of evidence Level III.

Risk factors for adverse cardiac events in hip fracture patients: an analysis of NSQIP data.

PURPOSE: Cardiovascular complications constitute morbidity and mortality for hip fracture patients. Relatively little data exist exploring risk factors for post-operative complications. Using the American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database, we identified significant risk factors associated with adverse cardiac events in hip fracture patients and provide recommendations for practising orthopaedists. METHODS: A cohort of 27,441 patients with hip fractures from 2006 to 2013 was identified using Current Procedural Terminology codes. Cardiac complications were defined as cardiac arrests or myocardial infarctions occurring within 30 days after surgery. Bivariate analysis was run on over 30 patient and surgical factors to determine significant associations with cardiac events. Multivariate logistical analysis was then performed to determine risk factors most predictive for cardiac events. RESULTS: Of the 27,441 hip fracture patients, 594 (2.2%) had cardiac complications within 30 days post-operatively. There was no significant association with respect to type of hip fracture surgery and adverse cardiac event rates (p = 0.545). After multivariate analysis, dialysis use (OR: 2.22, p = 0.026), and histories of peripheral vascular disease (OR: 2.11, p = 0.016), stroke (OR: 1.83, p = 0.009), COPD (OR: 1.69, p = 0.014), and cardiac disease (OR: 1.55, p = 0.017) were significantly predictive of post-operative cardiac events in all hip fracture patients. CONCLUSION: Orthopaedic trauma surgeons should be aware of cardiac disease history and atherosclerotic conditions (PVD, stroke) in risk stratifying patients to prevent cardiac complications. Our recommendations to reduce cardiac events include simple pre-operative lab-work to full-fledged cardiac work-up and referrals to specific medicine disciplines based on the specific risk factors present.

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.

Locking Versus Nonlocking Implants in Isolated Lower Extremity Fractures: Analysis of Cost and Complications.

The purpose of this study was to investigate operative costs and postoperative complication rates in relation to utilization of locking versus nonlocking implants in isolated, lower limb fractures. Seventy-seven patients underwent plate fixation of isolated bicondylar tibial plateau, bimalleolar ankle, and trimalleolar ankle fractures at a large tertiary care center. Fixation with locking versus nonlocking implants was compared to incidence of postsurgical complications. Costs of these implants were directly compared. No significant correlation was found between locking versus nonlocking implants and incidence of complications. However, the cost of fixation with locking implants was significantly greater than nonlocking for all fractures. Utilization of more costly locking implants was not associated with reduced postoperative complications compared with nonlocking implants. More attention must be dedicated toward maximizing cost efficiency, since uniform usage of nonlocking implants has the potential to reduce surgical costs without compromising patient outcomes in isolated lower extremity fractures.

American Society of Anesthesiologists Score as a Predictive Tool to Optimize Blood Ordering for Intraoperative Transfusion in Orthopaedic Trauma Cases.

The objective of this study was to determine the clinical factors that are predictors for intraoperative transfusion in orthopaedic trauma patients. A retrospective chart review of patients admitted to a level I trauma center with isolated fractures was conducted. Variables such as gender, height, weight, body mass index, American Society of Anesthesiologists (ASA) classification, and medical comorbidities were assessed to determine likelihood of blood transfusion. A total of 1819 patients with isolated fractures were identified. ASA class was strongly associated with patients receiving intraoperative blood transfusion. For example, compared with patients with an ASA class I, patients with an ASA class IV were 14.71 times more likely to receive transfusion. Patients' ASA class is correlated with the need for intraoperative blood transfusion in patients undergoing orthopaedic surgery for isolated fractures. Institutional or departmental maximum surgical blood order schedule algorithms could use patients' preoperative ASA class to determine whether blood transfusion will be necessary during procedures.

Predictors of Adverse Events for Ankle Fractures: An Analysis of 6800 Patients.

Ankle fractures are one of the most common injuries seen by orthopedic surgeons. It is therefore essential to understand the risks associated with their treatment. Using the American College of Surgeons National Surgical Quality Improvement Program(®) database from 2006 to 2013, the patient demographics, comorbidities, and 30-day complications were collected for 5 types of ankle fractures. A bivariate analysis was used to compare the patient demographics, comorbidities, and complications across all Common Procedural Terminology codes. A multivariable logistic regression model was then used to assess the odds of minor and major postoperative complications within 30 days after open treatment. A total of 6865 patients were included in the analysis. Of these patients, 2507 (36.5%) had bimalleolar ankle fractures. The overall rate of adverse events for ankle fractures was low. Bimalleolar fractures had the greatest rate of major (2.6%, n = 64), minor (3.8%, n = 94), and total (5.7%, n = 143) complications. When controlling for individual patient characteristics, bimalleolar fractures were associated with 4.92 times the odds (95% confidence interval 1.80 to 13.5; p = .002) of developing a complication compared with those with a medial malleolar fracture. The risk factors driving postoperative complications for all ankle fractures were age >65 years, obesity, diabetes, American Society of Anesthesiologists score >2, and functional status (p < .05). Although the overall rate of adverse events for ankle fractures was low, bimalleolar fractures were associated with 5 times the odds of developing a complication compared with medial malleolar fractures. Orthopedic surgeons must be aware of the risk factors that increase the rate of ankle fracture complications to improve patients' quality of care.

Use of the National Surgical Quality Improvement Program in orthopaedic surgery.

BACKGROUND: The goal of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) is to improve patient safety. The database has been used by hospitals across the United States to decrease the rate of adverse events and improve surgical outcomes, including dramatic decreases in 30-day mortality, morbidity, and complication rates. However, only a few orthopaedic surgical studies have employed the ACS NSQIP database, all of which have limited their analysis to either single orthopaedic procedures or reported rates of adverse events without considering the effect of patient characteristics and comorbidities. QUESTION/PURPOSES: Our specific purposes included (1) investigating the most common orthopaedic procedures and 30-day adverse events, (2) analyzing the proportion of adverse events in the top 30 most frequently identified orthopaedic procedures, and (3) identifying patient characteristics and clinical risk factors for adverse events in patients undergoing hip fracture repair. METHODS: We used data from the ACS NSQIP database to identify a large prospective cohort of patients undergoing orthopaedic surgery procedures from 2005 to 2011 in more than 400 hospitals around the world. Outcome variables were separated into the following three categories: any complication, minor complication, and major complication. The rate of adverse events for the top 30 orthopaedic procedures was calculated. Bivariate and multivariate analyses were used to determine risk factors for each of the outcome variables for hip fracture repair. RESULTS: Of the 1,979,084 surgical patients identified in the database, 146,774 underwent orthopaedic procedures (7%). Of the 30 most common orthopaedic procedures, the top three were TKA, THA, and knee arthroscopy with meniscectomy, which together comprised 55% of patients (55,575 of 101,862). We identified 5368 complications within the top 30 orthopaedic procedures, representing a 5% complication rate. The minor and major complication rates were 3.1% (n = 3174) and 2.8% (n = 2880), respectively. The most common minor complication identified was urinary tract infection (n = 1534) and the most common major complication identified was death (n = 850). An American Society of Anesthesiologists class of 3 or higher was a consistent risk factor for all three categories of complications in patients undergoing hip fracture repair. CONCLUSIONS: The ACS NSQIP database allows for evaluating current trends of adverse events in selected surgical specialties. However, variables specific to orthopaedic surgery, such as open versus closed injury, are needed to improve the quality of the results.

Geographic variations in hospital charges and Medicare payments for major joint arthroplasty.

National data on hospital-level charges and Medicare payments have shown that joint arthroplasty is the most common surgical procedure among the elderly. Yet, no study has investigated micro and macro level geographic variations in hospital charges and payment. We used the Medicare Provider Charge Data to investigate Medicare payments and charges for 2750 hospitals accounting for 427,207 patients who underwent major joint arthroplasty and 932 hospitals for 18,714 patients who had a complication/comorbidity. We found a significant difference in hospital charges and payments based on geographic region (P<0.001). We concluded that hospital charges demonstrate a high variability even when using areas to control for differences in hospital wages and high variation in reimbursements in some areas remains unexplained by Medicare's current method of calculating reimbursement.

The risk of adverse events in orthopaedic trauma varies by anatomic region of surgery: an analysis of fifty thousand four hundred and twenty one patients.

PURPOSE: Despite the high-risk nature of orthopaedic trauma, there is a dearth of data exploring adverse events following these interventions. With the current shift towards a reimbursement model grounded on episode-based payments, physicians may face financial penalties for higher rates of peri-operative complications and subsequent hospitalisations. The purpose of this study was thus to assess whether complication rates varied by anatomic region of surgery and to subsequently determine the pre-operative risk factors that elevated patients' chances of developing complications in these regions. METHODS: A total of 50,421 orthopaedic trauma patients treated between 2006 and 2013 were identified in the American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) database. Minor and major complications, demographics, surgical variables and pre-operative comorbidities were collected. Chi-square analyses identified pre-operative differences between the three regions. Multivariate regressions identified risk factors that significantly predicted adverse events. RESULTS: Hip and pelvis (HP) patients were found to be approximately seven times more likely to develop a peri-operative complication than upper extremity (UE) patients [odds ratio (OR) 7.38, 95 % confidence interval (CI) 6.33-8.10, p < 0.001]. In addition, lower extremity (LE) patients were found to be almost three times as likely to develop any complication compared to UE patients (OR 2.80, 95 % CI 2.53-3.09, p < 0.001). Certain risk factors, such as chronic obstructive pulmonary disease (COPD) and the presence of a bleeding disorder, were significantly correlated with the development of all adverse events for all anatomic regions (p < 0.001). CONCLUSIONS: There is a significant difference in complication rates between the three cohorts of orthopaedic trauma patients. In addition, the predictability of certain risk factors varied between the three regions. LEVEL OF EVIDENCE: prognostic level II.

Regional anaesthesia for hip fracture surgery is associated with significantly more peri-operative complications compared with general anaesthesia.

INTRODUCTION: Although several studies have advocated the use of regional versus general anaesthesia as a means of reducing peri-operative complications from hip fracture surgery, the ideal method of anaesthesia remains controversial. Our purpose was to investigate the association between anaesthesia type and peri-operative complications in hip fracture surgery. METHODS: From the 2005-2011 ACS-NSQIP database, all patients with operatively treated hip fractures were identified using CPT codes, and fifteen peri-operative complications were recorded and categorized as either minor or major. Rates of minor, major, and total complications by anaesthesia type were compared using chi-square and Fischer's exact tests. A multivariate model was used to determine odds of minor, major, and total complications between anaesthesia types. Multivariate analysis was then repeated after combining patients who received regional nerve blocks or spinal anaesthesia. RESULTS: A total of 7,764 hip fracture patients were included in our analysis. Spinal anaesthesia had the highest total complication rate (19.6%), followed by general (17.9%) and regional nerve blocks (12.6%). Multivariate analysis demonstrated that spinal anaesthesia was associated with significantly greater odds of minor complications and total complications compared with general anaesthesia. After combining the regional nerve block and spinal anaesthesia groups, multivariate analysis again showed significantly greater odds of minor and total complications with regional versus general anaesthesia. CONCLUSIONS: Using a large multi-centre database, we demonstrate that regional anaesthesia was associated with significantly greater odds of minor and total peri-operative complications compared with general anaesthesia. Our results challenge the notion that regional anaesthesia is the preferred method of anaesthesia for hip fractures in the elderly.

Impact of type of surgery on deep venous thrombi and pulmonary emboli: a look at twenty seven thousand hip fracture patients.

PURPOSE: Deep venous thrombi (DVT) and pulmonary emboli (PE) are common complications in hip fracture patients. It is imperative that orthopaedists know the patient risk factors for DVT and PE, including if type of surgery plays a role. To this end, we used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to identify significant risk factors. METHODS: From the 2006-2011 ACS NSQIP database, 27,441 patients with hip fractures were identified using a Current Procedural Terminology (CPT) code search. DVT and PE complications, type of surgery based on CPT code, patient demographics, medical comorbidities and operative factors were identified for each patient. Fisher's exact tests were used to (1) determine if rates of DVT and PE significantly differed based on type of surgery and (2) identify significant associations between patient factors and development of DVT/PE. These significant factors were then used as covariates in multivariable analysis to determine which risk factors predicted postoperative DVT/PE. RESULTS: Of the 27,441 hip fracture patients, 449 (1.6 %) developed DVT/PE. There was a significant difference in rates of DVT/PE based on surgery (p = 0.015): patients undergoing intramedullary nailing of inter-/peri-/subtrochanteric femoral fractures had the highest rates of DVT/PE (2.06 %). After multivariate analysis, renal failure and recent surgery were significant risk factors for DVT/PE. CONCLUSIONS: This study was the first to show through large, multicentre, prospective data that type of hip fracture surgery impacts rates of DVT/PE. We further identified two additional risk factors orthopaedists should be aware of. Knowing these risk factors will help in peri-operative planning to reduce complications.

What factors influence follow-up in orthopedic trauma surgery?

BACKGROUND: Among surgical patients, follow-up visits are essential for monitoring post-operative recovery and determining ongoing treatment plans. Non-adherence to clinic follow-up appointments has been associated with poorer outcomes in many different patient populations. We sought to identify factors associated with non-attendance at follow-up appointments for orthopedic trauma patients. MATERIALS AND METHODS: A retrospective chart review at a level I trauma center identified 2,165 patients who underwent orthopedic trauma surgery from 2008 to 2009. Demographic data including age, sex, race, tobacco use, American Society of Anesthesiologist (ASA) score, insurance status, distance from the hospital, and follow-up time were collected. Injury characteristics including fracture type, anatomic location of the operation, length of hospital stay, living situation and employment status were recorded. Attendance at the first scheduled follow-up visit was recorded. Multivariable log-binomial regression analyses were used with statistical significance maintained at p < 0.05. RESULTS: Of the 2,165 patients included in the analysis, 1,449 (66.9 %) attended their first scheduled post-operative clinic visit. 33.1 % (717) were not compliant with keeping their first clinic appointment after surgery. Patients who used tobacco, lived more than 100 miles from the clinic site, did not have private insurance, had an ASA score >2, or had a fracture of the hip or pelvis were significantly less likely to follow-up. Age, sex, and race were not significantly associated with failure to follow-up. DISCUSSION: Follow-up appointments are essential for preventing complications among orthopedic trauma patients. By identifying patients at risk of failure to follow-up, orthopedic surgeons can appropriately design and implement long-term treatment plans specifically targeted for high-risk patients.

Asking for the 22-modifier in isolated ankle fractures: does the operative note make the case?

We evaluated the operative notes for justification on the use of the 22-modifier in ankle fracture cases and compared the differences in physician billing and reimbursement. A total of 265 patients who had undergone operative management of isolated ankle fractures across a 10-year period were identified at a level I trauma center through a retrospective chart review. Of the 265 patients, 61 (23.0%) had been billed with the 22-modifier. The radiographs were reviewed by 3 surgeons to determine the complexity of the case. The amount of the professional fees and payments was obtained from the financial services department. Operative reports were reviewed for inclusion of eight 22-modifier criteria and word count. Mann-Whitney U tests of means were used to compare cases with and without the 22-modifier. From our analysis of preoperative radiographs, 37 (60%) showed evidence of a significantly complex fracture that justified the use of the 22-modifier. A review of the operative reports showed that 42 (68%) did not identify 2 or more reasons for requesting the 22-modifier in the report. Overall, the 22-modifier cases were not always reimbursed significantly greater amounts than the nonmodifier cases. No significant difference in the average word count of the operative notes was found. We have concluded that orthopedic trauma surgeons do not appropriately justify the use of the 22-modifier within their operative report. Further education on modifiers and the use of the operative report as billing documentation is required to ensure surgeons are adequately reimbursed for difficult trauma cases.

Ankle Fractures and Modality of Hospital Transport at a Single Level 1 Trauma Center: Does Transport by Helicopter or Ground Ambulance Influence the Incidence of Complications?

In an era of concern over the rising cost of health care, cost-effectiveness of auxiliary services merits careful evaluation. We compared costs and benefits of Helicopter Emergency Medical Service (HEMS) with Ground Emergency Medical Service (GEMS) in patients with an isolated ankle fracture. A medical record review was conducted for patients with an isolated ankle fracture who had been transported to a level 1 trauma center by either HEMS or GEMS from January 1, 2000 to December 31, 2010. We abstracted demographic data, fracture grade, complications, and transportation mode. Transportation costs were obtained by examining medical center financial records. A total of 303 patients was included in the analysis. Of 87 (28.71%) HEMS patients, 53 (60.92%) had sustained closed injuries and 34 (39.08%) had open injuries. Of the 216 (71.29%) GEMS patients, 156 (72.22%) had closed injuries and 60 (27.78%) had open injuries. No significant difference was seen between the groups regarding the percentage of patients with open fractures or the grade of the open fracture (p = .07). No significant difference in the rate of complications was found between the 2 groups (p = 18). The mean baseline cost to transport a patient via HEMS was $10,220 + a $108/mile surcharge, whereas the mean transport cost using GEMS was $976 per patient + $16/mile. Because the HEMS mode of emergency transport did not significantly improve patient outcomes, health systems should reconsider the use of HEMS for patients with isolated ankle fractures.
