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.

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.

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.

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.

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.

Distal tibia fractures and medial plating: factors influencing re-operation.

PURPOSE: We compared types of complications leading to re-operations in open and closed distal tibia fractures treated by locking or nonlocking medial plates. METHODS: Ninety-three patients from 2002 to 2012 who underwent open reduction and internal fixation (ORIF) and medial plating for distal extra-articular or partial articular tibia fractures were identified. Charts were retrospectively reviewed to determine the incidence of re-operation based on the type of complication that developed. Fisher's exact and chi-square tests were performed to analyze the incidence of complications based on injury and type of plate used. RESULTS: Thirty-three (35.5 %) patients required re-operations: 28.6 % (n = 16) with closed injuries had complications leading to re-operations compared with 45.9 % (n = 17) of patients with open injuries (p = 0.12). Patients with closed injuries were more likely to require re-operation due to hardware pain/prominence (p = 0.03), whereas patients with open injuries were more likely to require re-operation due to nonunion (p = 0.04). There were no significant differences in infection (p = 0.66) or malunion (p = 0.99) between groups. Locking plates showed higher costs but were not associated with decreased risk of re-operation. CONCLUSIONS: There was a high re-operation rate associated with distal tibia medial plating, with significant differences in the reason for re-operation between open versus closed groups. Complication rates were not influenced by the use of locking plates. Results of this study suggest that methods be considered to reduce re-operation based on type of fracture, such as early bone grafting or the use of alternate implants for open fractures.

Olecranon fractures: factors influencing re-operation.

PURPOSE: We evaluated factors influencing re-operation in tension band and plating of isolated olecranon fractures. METHODS: Four hundred eighty-nine patients with isolated olecranon fractures who underwent tension band (TB) or open reduction internal fixation (ORIF) from 2003 to 2013 were identified at an urban level 1 trauma centre. Medical records were reviewed for patient information and complications, including infection, nonunion, malunion, loss of function or hardware complication requiring an unplanned surgical intervention. Electronic radiographs of these patients were reviewed to identify Orthopaedic Trauma Association (OTA) fracture classification and patients who underwent TB or ORIF. RESULTS: One hundred seventy-seven patients met inclusion criteria of isolated olecranon fractures. TB was used for fixation in 43 patients and ORIF in 134. No statistical significance was found when comparing complication rates in open versus closed olecranon fractures. In a multivariate analysis, the key factor in outcome was method of fixation. Overall, there were higher rates of infection and hardware removal in the TB compared with the ORIF group. CONCLUSIONS: Our results demonstrate that the dominant factor driving re-operation in isolated olecranon fractures is type of fixation. When controlling for all variables, there is an increased chance of re-operation in patients with TB fixation.

A survey finds low rates for femtosecond laser-assisted cataract surgery, intracameral antibiotics, and immediate sequential bilateral cataract surgery in cataract surgery practice.

Student-Driven Approaches to Undergraduate Medical Research: A Peer-Led Symposium.

Exposure to research early in medical school facilitates the development of physician-scientists and competent clinicians. In the last decade, institutions have established programs and policies to address the physician- scientist shortage. However, student-led initiatives to promote medical student engagement in research remain unexplored. This paper presents the design and results of the third iteration of a symposium in which senior medical students provided guidance and advice to preclinical students interested in research. It also reviews the lessons learned from three years of conducting the symposium. [Full article available at http://rimed.org/rimedicaljournal-2016-08.asp, free with no login].

Pseudotumor cerebri: What We Have Learned from the Idiopathic Intracranial Hypertension Treatment Trial.

Idiopathic intracranial hypertension, also known as pseudotumor cerebri, is an unexplained increase in intracranial pressure associated with permanent severe visual loss in 25% of cases and debilitating headaches. The condition is often associated with obesity. The Idiopathic Intracranial Hypertension Treatment Trial, a large, randomized, collaborative clinical trial, evaluated the efficacy of acetazolamide with weight loss versus placebo with weight loss in participants. Herein, we describe the major components of the clinical trial and discuss its shortcomings. [Full article available at http://rimed.org/rimedicaljournal-2016-05.asp, free with no login].

Placing Bundled Payments in Perspective: A Survey of the New England Ophthalmological Society.

OBJECTIVE: To determine ophthalmologists' views on the Medicare bundled payment model for specialty physicians in the outpatient setting. DESIGN AND METHODS: The New England Ophthalmology Society (NEOS) was emailed an anonymous survey. Views of bundled payments and demographic characteristics were analyzed. RESULTS: Of responding members, 72% (115/160) strongly opposed bundled payments; 68% (108/160) believed bundled payments will lead to financial losses, and the majority did not support including costs of prescription drugs (69%, 109/159) or preoperative (77%, 123/159) or postoperative complications (59%, 94/159) in the bundle. Respondents who held office in a medical society, were in private practice, solely billed for income, and had mostly conservative political views were significantly more likely to oppose bundling. CONCLUSION: The majority of NEOS ophthalmologists were opposed to bundled payments. Personal beliefs and practice type may influence the level of ophthalmologist support of bundled payments.

ASA score as a predictor of 30-day perioperative readmission in patients with orthopaedic trauma injuries: an NSQIP analysis.

OBJECTIVE: Our purpose was to identify the impact of the physical status of the American Society of Anesthesiologists (ASA) on the 30-day readmission of patients receiving operative management of orthopaedic fractures using the National Surgical Quality Improvement Program (NSQIP) database. METHODS: We analyzed all patients with orthopaedic trauma injuries in the American College of Surgeons NSQIP database from 2005 to 2011. A total of 8761 patients representing 91 orthopaedic trauma procedures were identified and included in analysis after selection. Logistic regressions were conducted to identify the predictive ability of ASA on the likelihood of readmission for patients in each anatomic category (upper extremity, pelvis/acetabulum, lower extremity) and the combined study population. RESULTS: The ASA physical status proved the strongest predictor of 30-day readmission for the selected orthopaedic trauma procedures. After controlling for age, gender, race, and medical comorbidities that were shown to be significant independent risk factors for readmission, ASA score continued to have a significant association on 30-day readmissions in the combined population (odds ratio = 1.45, 95% confidence interval = 1.13-1.88, P = 0.001). For the combined analysis, compared with patients with an ASA score of 1, patients with an ASA score of 2 were 1.04 times as likely to have a readmission (P = 0.001), patients with an ASA score of 3 were 3.77 times as likely to have a readmission (P = 0.001), and patients with an ASA score of 4 were 13.7 times as likely to have a readmission (P = 0.001). CONCLUSIONS: ASA classification is an indicator for variance in readmission for patients receiving operative treatment of orthopaedic fractures. Given that ASA classification is a universally collected data point, this method can be used in almost any hospital system and for any operative service. This model may be used to more accurately predict a patient's postoperative course and the expected risk for readmission, such that hospitals can target these "at-risk" individuals and reduce 30-day readmissions. LEVEL OF EVIDENCE: Prognostic level II. See Instructions for authors for a complete description of levels of evidence.

Factors driving readmissions in tibia and femur fractures.

As the American healthcare system shifts towards bundled payments, readmissions will become a measure of healthcare quality. The purpose of this study was to characterize readmission trends and factors influencing readmission in patients with diaphyseal femur and tibia fractures. Through a retrospective chart review, all patients who presented to a level 1 trauma center from 2004 to 2006 were evaluated. By using current procedural terminology codes, 1,040 patients with diaphyseal tibia or femur fractures fixed by IMN were identified. 645 patients were included for analysis. 30-day, 60-day, and 90-day readmission rates were compared with fracture type, reason for readmission, and basic demographic information. The 60-day readmission rate for open tibia fractures (14.8%) was significantly higher than the 60-day readmission rate for closed tibia fractures (8.0%) (p = 0.037). When comparing reasons for 60-day readmissions, 50% of closed fractures were readmitted due to infection, while the other 50% needed additional surgery. 91.7% of open fractures readmitted in 60 days were due to infection. In a bundled payment system, orthopedic trauma must gain insight into drivers of readmission to identify those at risk for readmission and design effective healthcare plans for these patients.

Prospective randomized controlled trial using telemedicine for follow-ups in an orthopedic trauma population: a pilot study.

OBJECTIVES: To compare patient satisfaction between telemedicine and in-person follow-up appointments for orthopedic trauma. DESIGN: Prospective randomized controlled trial (pilot study). SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: Twenty-four patients were enrolled and randomized into 2 groups. Eight patients who had telemedicine follow-up appointments and 9 who had in-person follow-up visits were included in a per-protocol analysis. In the telemedicine group, 2 patients left the study because of nonadherence, 1 patient withdrew because of a weak Internet connection, and 1 patient sustained an open fracture. Three control patients left the study because of nonadherence. INTERVENTION: The patients had 4 follow-up appointments during a 6-month period. Patients either had their 6-week and 6-month follow-ups through video calls or in the clinic. MAIN OUTCOME MEASUREMENTS: After 6-week and 6-month follow-up appointments, the patients were given survey questions that were developed using literature-supported methods to compare follow-up experiences. The patients were monitored for complications. RESULTS: There was no significant difference in patient satisfaction between telemedicine and in-person clinic visits (telemedicine: 89% satisfied; control: 100% satisfied; P = 0.74). Zero percent of patients in the telemedicine group took time off their work for their appointment compared with 55.6% in the control (P = 0.03). Telemedicine patients spent significantly less time on their visits (P = 0.01). The majority of the patients in the telemedicine group reported clear visual (87.5%) and sound quality (100%) through and agreed to future follow-up visits through telemedicine (75.0%). One patient in each group developed complications. CONCLUSIONS: Telemedicine may be a viable alternative to some in-person clinic visits because of similar measures of patient satisfaction but with significantly less time and distance traveled. LEVEL OF EVIDENCE: Therapeutic level II. See Instructions for authors for a complete description of levels of evidence.
