Breast Cancer Incidence, Mortality, and Cost in Adolescent Idiopathic Scoliosis Patients and the Role of Low Dose Biplanar Radiography.

INTRODUCTION: Patients with adolescent idiopathic scoliosis (AIS) are susceptible to high doses of radiation from radiographs. The purpose of this study was to examine the future cost of radiation-induced breast cancer in patients with AIS and its potential financial and mortality impact. METHODS: A literature review identified articles relating radiation exposure in patients with AIS to increased risk for cancer. Based on population statistics and breast cancer treatment costs in the year 2020, the financial impact of radiation-induced breast cancer and the estimated number of additional deaths per year due to breast cancer for patients with AIS were calculated. RESULTS: The US female population in 1970 was 205.1 million. Based on a prevalence of 3.0%, an estimated 3.1 million patients had AIS in 1970. With an incidence of breast cancer in the general population of 128.3/100,000 and a standardized incidence ratio of 1.82-2.4 for breast cancer in patients with scoliosis, there will be a 3,282 to 5,603 patient increase in radiation-induced breast cancer in patients with scoliosis over the general population. With a projected base cost of $34,979 per patient for the first year of breast cancer diagnosis in 2020, the cost of radiation-induced breast cancer will be 114.8 to 196.0 million dollars per year. Using a standardized mortality ratio of 1.68 for scoliosis radiation-induced breast cancer, there will be an expected increase in deaths of 420 patients due to breast cancer presumably secondary to radiation exposure in the evaluation and treatment of AIS. CONCLUSION: The estimated radiation-induced breast cancer financial impact in 2020 will be between 114.8 and 196.0 million dollars per year, with an increase in deaths of 420 patients per year. Low-dose imaging systems reduce radiation exposure by up to 45 times while maintaining sufficient image quality. New low-dose radiography should be used whenever possible with patients with AIS. LEVEL OF EVIDENCE: Level 5.

Accelerated Discharge Protocol for Posterior Spinal Fusion Patients With Adolescent Idiopathic Scoliosis Decreases Hospital Postoperative Charges 22.

STUDY DESIGN: A retrospective study of consecutive patients. OBJECTIVE: The purpose of this study was to determine implementing an accelerated protocol could decrease our average hospital stay and what impact this had on postoperative pain management. SUMMARY OF BACKGROUND DATA: To our knowledge, no prior studies have reviewed the effect of an accelerated discharge protocol on postoperative pain control for adolescent idiopathic scoliosis (AIS) following posterior spinal fusion. METHODS: This is a retrospective review of all consecutive patients undergoing posterior spinal fusion (PSF) for AIS before (June 1, 2008-May 31, 2013 = traditional protocol) and after (June 1, 2013-October 22, 2014 = accelerated protocol) protocol implementation. Subjective response to the FACES Pain Intensity scale was collected for each postoperative day while in the hospital by the nursing staff. RESULTS: There were 194 patients in the traditional pathway and 90 patients in the accelerated pathway. No significant differences in age at surgery, sex, or number of levels fused were present between the groups. Patients managed under the accelerated discharge had an average hospital stay of 3.7 days compared with 5.0 days for the traditional discharge (P < 0.001). There was no increased incidence of wound complications between the two groups [3.6% (7/194) vs. 3.3% (3/90), P = 0.91] or readmission [1.5% (3/194) vs. 4.4% (4/90), P = 0.213]. Hospital charges for postoperative care were significantly less in the accelerated discharge group than in the traditional group ($18,360 vs. $23,640, P < 0.0001). This corresponded to a 22% ($5280/$23,640) decrease in postoperative hospital charges. Patients had a small (<1 point change on FACES pain scale) but statistically significant increase in pain on postoperative days 2, 3, and 4 (P = 0.0001, P = 0.0079, P = 0.0076). CONCLUSION: Accelerated discharge following PSF for AIS was associated with a 22% decrease in hospital charges in the postoperative period. LEVEL OF EVIDENCE: 4.

Assessment of Lowest Instrumented Vertebra Tilt on Radiographic Measurements in Lenke "C" Modifier Curves Undergoing Selective Thoracic Fusion in Adolescent Idiopathic Scoliosis.

STUDY DESIGN: Multicenter, retrospective cohort study. OBJECTIVES: The purpose of this study is to determine how the amount of residual lowest instrumented vertebra (LIV) tilt correlates with radiographic measurements. SUMMARY OF BACKGROUND DATA: When performing a selective thoracic posterior spinal fusion for adolescent idiopathic scoliosis (AIS), the LIV may be tilted into the lumbar curve or made horizontal. METHODS: This is a multicenter retrospective study of 33 consecutive patients with AIS, Lenke types 1 to 4, lumbar modifier C, and a minimum follow-up of 2 years, who underwent selective thoracic posterior spinal fusions. Measurements obtained from pre- and postoperative radiographs were correlated with postoperative LIV tilt. RESULTS: At final follow-up, less postoperative LIV tilt significantly correlated with less thoracic apical translation (p = .023) when controlling for the position of the LIV relative to the stable vertebra and preoperative thoracic and lumbar curve flexibility. LIV tilt was not significantly associated with thoracic Cobb angle, lumbar Cobb angle, lumbar apical translation, coronal balance, sagittal balance, or the amount of correction obtained compared to their preoperative measurements (p > .05). CONCLUSION: Decreased LIV tilt was significantly associated with decreased thoracic apical translation. LIV tilt did not significantly correlate with coronal balance or any other radiographic measurement. We caution that these findings may only be applicable in C modifier curves and when the correct LIV is chosen. LEVEL OF EVIDENCE: Level III, Therapeutic study.

Insurance status does not predict curve magnitude in adolescent idiopathic scoliosis at first presentation to an orthopaedic surgeon.

BACKGROUND: Previous studies have identified that children with public insurance have limited access to orthopaedic care. The purpose of this study was to explore the relationship between insurance status and curve magnitude at the time of presentation to an orthopaedic surgeon and time to treatment at a tertiary pediatric medical center. METHODS: This study was retrospective review of all patients with idiopathic scoliosis over 10 years, who have not had previous spine surgery. Data were collected on demographics, insurance type, curve magnitude at presentation, source of referral, treatment initiated, and time from recommendation for surgery to surgical intervention. RESULTS: Of the 642 patients included in this study, 53% were publicly insured and 45% were privately insured. Privately insured patients were significantly more likely to be seen as a second opinion (30% vs. 10%, P<0.001), and were significantly more likely to have received previous treatment (8% vs. 4%, P=0.011). Publicly insured patients were significantly more likely to be referred by their primary care doctor (64% vs. 50%, P=0.001) or as a part of school screening program (20% vs. 13%, P=0.036). At the time of presentation, there was no significant difference detected in major Cobb angles in the privately insured group [(private=28.7 (±15.4) degrees vs. public=26.4 (±16.8) degrees, P=0.076)]. There was no significant difference between the 2 groups in the number of patients who were recommended for operative treatment (public=11% vs. private 16%, P=0.072). However, in a multivariate regression analysis, publicly insured patients waited an average of 2.6 months longer for surgery than privately insured patients (P=0.010). CONCLUSIONS: Patients with private insurance presenting for evaluation of idiopathic adolescent scoliosis were significantly more likely to present as a second opinion than those with government insurance. In this group of 642 patients, no significant differences were found in major Cobb angle at presentation or eventual need for surgery. LEVEL OF EVIDENCE: Level III.

National access to care for children with fractures.

BACKGROUND: Access to health care for many pediatric orthopaedic patients is becoming more difficult. In some communities, children with fractures have limited access to care regardless of insurance status. The purpose of this study was to determine the level of difficulty in obtaining access to care for children with fractures nationally and compare our results to the published results of a national survey in 2006. METHODS: Five orthopaedic offices were identified in each state using an internet search with Google maps by typing "general orthopedics" under the search heading for each state. Each office was contacted with a scripted phone call describing a fracture in a 10-year-old boy that does not involve the growth plate. The office was then told the patient has Medicaid insurance. If no appointment was given, the reason was recorded and the office was asked to refer us to another orthopaedic surgeon. A second phone call was made to the same office a few days later using the same script but the office was told the patient has a private preferred-provider organization insurance. If no appointment was given, the reason was recorded. RESULTS: Of the 250 (23.6%) offices across the country, 59 would see a pediatric fracture patient with Medicaid. 41.3% (79/191) of the offices refusing the patient stated that they do not accept Medicaid patients. Of the 250, 205 (82%) of the offices across the country would see a pediatric fracture patient with a private preferred-provider organization insurance. The 10 states with lowest Medicaid reimbursement offered an appointment 6% of the time, whereas the 10 best reimbursing states offered an appointment 44% of the time. DISCUSSION AND CONCLUSIONS: The access to care for children with fractures is becoming more difficult across the country. Compared with the published data in 2006, the number of offices willing to see a child with private insurance has decreased from 92% to 82%. The number of offices willing to see a child with a fracture and Medicaid insurance has decreased from 62% to 23% over the same time span.

Building consensus: development of a Best Practice Guideline (BPG) for surgical site infection (SSI) prevention in high-risk pediatric spine surgery.

BACKGROUND: Perioperative surgical site infection (SSI) after pediatric spine fusion is a recognized complication with rates between 0.5% and 1.6% in adolescent idiopathic scoliosis and up to 22% in "high risk" patients. Significant variation in the approach to infection prophylaxis has been well documented. The purpose of this initiative is to develop a consensus-based "Best Practice" Guideline (BPG), informed by both the available evidence in the literature and expert opinion, for high-risk pediatric patients undergoing spine fusion. For the purpose of this effort, high risk was defined as anything other than a primary fusion in a patient with idiopathic scoliosis without significant comorbidities. The ultimate goal of this initiative is to decrease the wide variability in SSI prevention strategies in this area, ultimately leading to improved patient outcomes and reduced health care costs. METHODS: An expert panel composed of 20 pediatric spine surgeons and 3 infectious disease specialists from North America, selected for their extensive experience in the field of pediatric spine surgery, was developed. Using the Delphi process and iterative rounds using a nominal group technique, participants in this panel were as follows: (1) surveyed for current practices; (2) presented with a detailed systematic review of the relevant literature; (3) given the opportunity to voice opinion collectively; and (4) asked to vote regarding preferences privately. Round 1 was conducted using an electronic survey. Initial results were compiled and discussed face-to-face. Round 2 was conducted using the Audience Response System, allowing participants to vote for (strongly support or support) or against inclusion of each intervention. Agreement >80% was considered consensus. Interventions without consensus were discussed and revised, if feasible. Repeat voting for consensus was performed. RESULTS: Consensus was reached to support 14 SSI prevention strategies and all participants agreed to implement the BPG in their practices. All agreed to participate in further studies assessing implementation and effectiveness of the BPG. The final consensus driven BPG for high-risk pediatric spine surgery patients includes: (1) patients should have a chlorhexidine skin wash the night before surgery; (2) patients should have preoperative urine cultures obtained; (3) patients should receive a preoperative Patient Education Sheet; (4) patients should have a preoperative nutritional assessment; (5) if removing hair, clipping is preferred to shaving; (6) patients should receive perioperative intravenous cefazolin; (7) patients should receive perioperative intravenous prophylaxis for gram-negative bacilli; (8) adherence to perioperative antimicrobial regimens should be monitored; (9) operating room access should be limited during scoliosis surgery (whenever practical); (10) UV lights need NOT be used in the operating room; (11) patients should have intraoperative wound irrigation; (12) vancomycin powder should be used in the bone graft and/or the surgical site; (13) impervious dressings are preferred postoperatively; (14) postoperative dressing changes should be minimized before discharge to the extent possible. CONCLUSIONS: In conclusion, we present a consensus-based BPG consisting of 14 recommendations for the prevention of SSIs after spine surgery in high-risk pediatric patients. This can serve as a tool to reduce the variability in practice in this area and help guide research priorities in the future. Pending such data, it is the unsubstantiated opinion of the authors of the current paper that adherence to recommendations in the BPG will not only decrease variability in practice but also result in fewer SSI in high-risk children undergoing spinal fusion. LEVEL OF EVIDENCE: Not applicable.

Intensive care unit versus hospital floor: a comparative study of postoperative management of patients with adolescent idiopathic scoliosis.

BACKGROUND: Patients undergoing posterior spinal instrumentation and fusion surgery for adolescent idiopathic scoliosis were admitted to the intensive care unit until two years ago, at which time we changed our protocol to admit these patients to the general hospital floor following a brief stay in a postanesthesia care unit. This study compared postoperative management on a hospital floor with that in the intensive care unit for patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion. METHODS: A retrospective review of 124 consecutive patients with adolescent idiopathic scoliosis treated with spinal fusion from August 2007 to August 2010 was performed. Inclusion criteria were a diagnosis of adolescent idiopathic scoliosis and posterior spinal instrumentation and fusion surgery. RESULTS: Of 124 patients, sixty-six were managed postoperatively in the intensive care unit and fifty-eight, on the hospital floor. The mean age at the time of surgery was fourteen years. A mean of eleven vertebral levels (range, six to fifteen levels) were fused. No significant difference between the groups was found with respect to the mean age at the time of surgery, mean weight, mean preoperative and postoperative Cobb angles, and mean number of levels fused (p ≥ 0.12). However, the use of analgesic and antianxiety medication, number of postoperative blood tests, days of hospital stay, and number of physical therapy sessions were significantly decreased in the floor group compared with the intensive care unit group (p ≤ 0.05). No patient from the floor group had to be admitted to the intensive care unit. The mean charge was $33,121 for the floor group and $39,252 for the intensive care unit group (p < 0.001). CONCLUSIONS: Initial postoperative management of patients with adolescent idiopathic scoliosis following a posterior spinal instrumentation and fusion surgery on a general hospital floor, rather than in an intensive care unit, was associated with a shorter hospital stay, fewer blood tests, less analgesic and antianxiety medication usage, and fewer physical therapy sessions at this high-volume, academic, tertiary-care children's hospital. In addition to improved patient outcomes, there was a significant decrease of 16% in hospital charges for the group that did not go to the intensive care unit.

Access to care for the adolescent anterior cruciate ligament patient with Medicaid versus private insurance.

PURPOSE: To determine the potential impact of type of health insurance on access to outpatient orthopaedic care for an adolescent patient with an acute anterior cruciate ligament (ACL) tear. METHODS: The offices of 42 orthopaedic surgeons in the Greater Cincinnati area, to include Ohio, Indiana, and Kentucky were contacted on 2 separate occasions describing a fictitious 14-year-old male with an acute ACL tear. The 2 calls were separated by a period of 2 to 4 weeks. The independent variable was the patient's insurance status, reported as either Medicaid or private insurance. Statistical comparison of the rates of successful appointment scheduling was performed through the Fisher exact test. RESULTS: Thirty-eight of 42 Orthopaedic surgery practices (90%) offered the privately insured 14-year-old ACL patient an appointment within 2 weeks, while only 6 of 42 (14%) offered the Medicaid patient such an appointment. The difference in these rates was statistically significant (P<0.0001) with the odds of getting an appointment with private insurance being 57 times higher than that with Medicaid (95% confidence interval: 12.87, 288.62). CONCLUSIONS: Access to orthopaedic care for children on Medicaid continues to be a problem in the United States. Previous pediatric studies have documented that the reason for these discrepancies in access are related primarily to Medicaid reimbursement rates (approximately 23% of private insurance). Ours is the first study to show that these same limitations exist for teenagers with acute knee injuries likely to require surgery.

Orthopedic surgeons are less likely to see children now for fracture care compared with 10 years ago.

OBJECTIVE: To assess availability of timely orthopedic fracture care to children. STUDY DESIGN: Fifty randomly selected orthopedic practices were contacted twice with an identical scenario to request an appointment for a fictitious child with an arm fracture, once with the staff told that the child had private insurance and once with Medicaid. Access to appointments on the basis of insurance was compared with rates 10 years earlier.(1) RESULTS: Forty-five practices were contacted successfully. An appointment was offered within 7 days to a child with private insurance by 42% of the practices (19/45) and to a child with Medicaid by 2% of the practices (1/45; P < .0001). There was no difference in timely access (appointment within 7 days) for children with Medicaid in this study (2%) compared with 10 years ago (1%; P = 1.0). There was a significant decrease in timely access for children with private insurance in the past decade, with a rate of 42% (19/45) in this study, compared with 100% (50/50) 10 years ago (P < .0001). CONCLUSION: There has been a substantial decrease in the last decade in the willingness, availability, or both of orthopedic surgeons in Los Angeles to care for children with fractures whose families have private insurance. Children with Medicaid continue to have limited access.

Access to care for children with fractures.

BACKGROUND: Earlier studies have found that children with fractures and PPO insurance have no access problems to orthopaedic care, but children with Medicaid have problems with access to orthopaedic care. METHODS: Fifty randomly selected orthopaedic offices in each of the 2 counties served by a children's hospital were telephoned to seek an appointment for a fictitious 10-year-old boy with a forearm fracture. Each office was called twice, 1 time reporting that the child had PPO insurance and 1 time that he was having Medicaid. In the second arm of the study, data including insurance status were prospectively collected on all patients with fractures seen in the emergency department of children's hospital. RESULTS: Of the 100 offices telephoned, 8 offices gave an appointment within 1 week to the child with Medicaid insurance. Thirty-six of the 100 offices gave an appointment within 1 week to the child with PPO insurance. For the 2210 pediatric fractures seen in the emergency department, the payer mix for patients presenting initially to our facility (1326 patients) was 41% Medicaid, 9% selfpay, and 50% commercial. For the patients presenting to our emergency department after being seen at an outside facility first (884 patients), the payer mix was 47% Medicaid, 13% self-pay, and 40% commercial. The percentages between these two groups were similar but did have a statistically significant difference (P=0.021). CONCLUSIONS: To the best of our knowledge, this is the first study that reports a majority (64/100) of orthopaedic offices in the region would not care for a child with a fracture regardless of insurance status. Consistent with earlier studies, children with Medicaid have less access to care. The similar insurance status of children sent to the emergency department from other facilities compared with those presenting directly suggests that children in this study are sent to a children's hospital for specialized care rather than for economic reasons. LEVEL OF EVIDENCE: Level II.

Aprotinin in pediatric neuromuscular scoliosis surgery.

Reduction of blood transfusions in patients with neuromuscular scoliosis can decrease potential complications such as immune suppression, infection, hemolytic reaction and viral transmission. Aprotinin (Trasylol), Bayer), an antifibrinolytic, has proven to be effective in reducing blood loss in cardiac and liver surgery, but little data exists in patients undergoing spinal fusion for neuromuscular scoliosis. The purpose of this study was to evaluate the safety and efficacy of aprotinin in pediatric neuromuscular scoliosis patients undergoing spinal fusion. The medical records of all patients undergoing initial spinal fusions for neuromuscular scoliosis between January 1999 and March 2003 were reviewed to determine demographic data, perioperative data, wound drainage and number of transfusion required. Cases were compared to a matched group of historical controls. We had 14 patients in the aprotinin group and 17 in the control group. Total blood loss in the aprotinin group was significantly lower compared to the control group (715 vs. 2,110 ml; P = 0.007). Significantly less blood loss occurred in the aprotinin group when blood loss per kilogram was evaluated as well (23 vs. 60 ml/kg, respectively; P = 0.002). Intra-operative packed red blood cell (PRBC) transfusions were also significantly lower in the aprotinin group (1.25 vs. 3.16 units; P = 0.001). No clinical evidence of anaphylaxis, deep vein thrombosis (DVT) or renal failure was observed in the aprotinin group. After considering the price of drug therapy, operating room time, and the cost of blood products, the use of aprotinin saved an average of $8,577 per patient. In our series, the use of aprotinin resulted in decreased blood loss and a decreased rate of transfusions in children with neuromuscular scoliosis undergoing extensive spinal fusion. At out institution, the use of aprotinin is safe and cost effective for patients with neuromuscular scoliosis.

Is research presented at the scoliosis research society annual meeting influenced by industry funding?

STUDY DESIGN: All abstracts submitted to the 2006 SRS annual meeting were reviewed. OBJECTIVE: To determine the rate of funding in abstracts submitted for presentation at the 2006 Annual Scoliosis Research Society (SRS) meeting and whether funding produced bias toward a positive outcome. SUMMARY OF BACKGROUND DATA: Financial conflicts of interest have been attributed to bias in research. METHODS: Three members the SRS Program Committee reviewed 610 abstracts submitted for presentation at the 2006 annual meeting. The committee's average grade was correlated with type of funding (industry, professional society, university); abstract conclusions (favorable, unfavorable, or only descriptive); and subject category [adolescent idiopathic scoliosis (AIS), motion preservation, etc.]. RESULTS: Of the 610 submitted articles, 72% (n = 440) were unfunded. Of the 170 funded articles, 140 were supported by industry, 7 by government agency, 8 by professional societies, 4 by universities, and 11 by private foundations. There was no statistically significant difference between the reviewers' grades of funded versus unfunded articles (P = 0.39). Comparing AIS articles to all the other categories, the number of funded articles were significantly greater only in motion preservation (P < 0.001) and genetics (P = 0.039). When a consultant/employee relationship was present, there was a significant difference in the proportion of funded articles and favorable findings (P = 0.048). CONCLUSION: The higher percentage of funded articles in motion preservation and genetics compared to AIS articles could reflect a bias in those 2 areas. However, although there were more funded articles in those 2 areas there were not more funded, favorable articles (motion preservation P = 0.059, and genetics P = 0.3). Thus, certain categories attracted more funding than others but there was not a bias toward favorable findings within the funded articles unless the funding was due to a consultant/employee relationship.

Insurance status and delay in orthotic treatment in children.

OBJECTIVE: To determine if the type of health insurance is associated with a delay in children obtaining orthoses. METHODS: The medical records of 60 children who were prescribed an ankle-foot orthosis (AFO) or thoracolumbosacral orthosis (TLSO) were retrospectively reviewed. Ten children were randomly chosen with either of 3 types of insurance (government, health maintenance organizations [HMOs], and preferred provider organizations [PPOs]) with an orthosis provided by a single supplier. The time interval between prescription and insurance company authorization was recorded, as well as the interval between prescription and procurement of the orthosis. RESULTS: There were significant differences in the time from prescription to authorization of orthoses between insurance types (P = 0.001) and time from authorization until brace procurement between insurance types (P = 0.01). Children with PPO insurance received authorization for an AFO faster than children with government insurance or an HMO (P < 0.05). Children with government insurance received authorization for a TLSO significantly later than children with PPO insurance (P = 0.004) or HMO insurance (P = 0.03). The difference in time between authorization and procurement of a TLSO in children with PPO insurance (36 days) was strikingly different from that of children with government insurance (123 days) (P = 0.003). DISCUSSION: This study documents that children with government insurance face delays in obtaining orthotic treatment compared with children with PPO insurance. The delay in the procurement of the more expensive brace (TLSO is approximately 4 times the cost of an AFO) correlated to more striking delays in the government-insured population.

Access to orthopaedic care for children with medicaid versus private insurance: results of a national survey.

BACKGROUND: It has been documented that children insured by Medicaid in California have significantly less access to orthopedic care than children with private insurance. Low Medicaid physician reimbursement rates have been hypothesized to be a major factor. The first objective of this study was to examine whether children insured by Medicaid have limited access to orthopedic care in a national sample. The second objective was to determine if state variations in Medicaid physician reimbursement rates correlate with access to orthopedic care. METHODS: Two-hundred fifty orthopedic surgeon's offices, 5 randomly chosen in each of 50 states, were telephoned. Each office called was asked to answer questions to an anonymous, disclosed survey. The survey asked whether the office accepted pediatric patients, whether they accepted children with Medicaid, and whether they limited the number of children that they accepted with Medicaid, and if so why. Each state sets its own rate of physician reimbursement rates that were collected from individual state Medicaid agencies for 3 different CPT codes. The relationship between acceptance of patients with Medicaid and the individual state's Medicaid reimbursement rate was examined. RESULTS: Children with Medicaid insurance had limited access to orthopedic care in 88 of 230 (38%) offices that treat children, and 18% (41/230) of offices would not see a child with Medicaid under any circumstances. Reimbursement rates for CPT codes widely varied by state: 99243 for an outpatient consultation (range, $20-$176.38), 99213 for an established follow-up outpatient visit (range, $6-$77.76), and 25560 for global treatment of a nondisplaced radius and ulna shaft fracture without manipulation (range, $50-$403.94). There was a statistically significant relationship between access to medical care for Medicaid patients and physician reimbursement rates for all 3 CPT codes. CONCLUSIONS: Children insured with Medicaid have limited access to orthopedic care in this nationwide sample. Medicaid physician reimbursement significantly correlates with patient access to medical care. These data may be of value in the ongoing efforts to improve access to medical care for children on Medicaid. The logical inference from this study is that increasing physician reimbursement rates will improve access. In the authors' opinion, reimbursement rates should be made higher than office overhead to effect meaningful change.

Comparison of the volume of scoliosis surgery between spine and pediatric orthopaedic fellowship-trained surgeons in New York and California.

BACKGROUND: Controversy exists regarding the optimal fellowship training experience for surgeons who perform scoliosis surgery in pediatric patients. While many studies have demonstrated that higher surgical volumes are associated with superior outcomes, the volume of scoliosis procedures performed by pediatric orthopaedic-trained surgeons as opposed to spine surgery-trained surgeons has not been reported. METHODS: Validated, statewide hospital discharge databases from the states of New York and California were utilized to examine the volume of spinal fusion procedures performed for the treatment of scoliosis in patients who were eighteen years of age or less. Fellowship training of surgeons in New York who had performed more than fifty procedures from 1992 to 2001 (that is, more than five procedures per year) was determined, and the operative volumes of surgeons who had received pediatric orthopaedic as opposed to spine fellowship training were compared. Hospitals in California with either type of fellowship program were identified, and the operative volumes of hospitals and fellows with pediatric orthopaedic or spine fellowship training from 1995 to 1999 were compared. RESULTS: Among the 228 surgeons in New York who had performed one or more spinal fusion procedures in patients eighteen years of age or less from 1992 to 2001, only 13% (thirty) had performed more than five procedures per year. However, these thirty surgeons accounted for 75% (3858) of all 5136 procedures in this age-group. Surgeons who had completed a pediatric orthopaedic fellowship had performed a mean of 14.5 procedures per physician per year, whereas those who had completed a spine fellowship had performed a mean of 10.5 procedures per physician per year. Surgeons who had not completed either type of fellowship had performed a mean of 14.4 procedures per physician per year. In California, the mean annual volume of scoliosis procedures from 1995 to 1999 was 59.0 procedures per year at hospitals with pediatric orthopaedic fellowship programs and 15.7 procedures per year at those with spine surgery programs. The mean number of procedures per fellow at hospitals with pediatric orthopaedic fellowship programs was 31.6 procedures per fellow per year, and the mean number at hospitals with spine surgery programs was 12.7 procedures per fellow per year. Over time, there was a significant increase in the number of procedures per year at hospitals with both types of fellowship programs, but the percentage increase was greater for hospitals with pediatric orthopaedic fellowship programs than for hospitals with spine surgery fellowship programs (45.2% compared with 13.5%). CONCLUSIONS: These data indicate that, on the average, a large number of surgeons in New York performed five scoliosis procedures per year or fewer. Among higher-volume surgeons in New York, those with pediatric orthopaedic fellowship training performed more scoliosis procedures on children and adolescents than those with orthopaedic spine training did. In California, the volume of scoliosis procedures at hospitals with pediatric orthopaedic fellowship programs was nearly four times greater than that at hospitals with spine fellowship programs and the volume of procedures per fellow was more than two times greater, and this disparity is widening over time. These data are an important element in establishing what type of fellowship best prepares surgeons for scoliosis surgery.

Access to urologic care for children in California: Medicaid versus private insurance.

OBJECTIVES: To compare the access to urologic care for a child with cryptorchidism insured by Medi-Cal versus one insured by private insurance. Medi-Cal (California State Medicaid) is a joint state and federal health insurance program that plays a significant role in providing healthcare coverage to low-income children. METHODS: A total of 54 randomly chosen urology offices throughout California were surveyed by telephone to determine whether the office accepted pediatric patients, accepted Medi-Cal, and when the earliest appointment date would be for a patient with Medi-Cal versus one with private insurance. RESULTS: Of the 46 practices that accepted pediatric patients, 96% offered a new patient appointment to a child with private insurance, but only 41% were willing to offer an appointment to a child with Medi-Cal (P < 0.0001). Of the offices that would not see a child with Medi-Cal, 75% were unable to recommend a urology office that might accept Medi-Cal. CONCLUSIONS: Children insured by Medi-Cal have significantly less access to necessary urologic care compared with children with private insurance.

The contribution of hospital volume, payer status, and other factors on the surgical outcomes of scoliosis patients: a review of 3,606 cases in the State of California.

While volume/outcomes relationships have been shown for several areas of orthopaedics, previous studies have not examined this relationship in the area of scoliosis surgery. The Office of Statewide Planning and Development (OSHPD) California inpatient discharge database was used for a retrospective review of all patients 25 years of age or younger with a diagnosis of scoliosis and a spinal fusion procedure from 1995 to 1999 (n = 3,606). Univariate and multivariate analyses were conducted to determine the effect of various factors on in-hospital mortality, surgical complications, reoperations, and length of stay (LOS). Univariate analyses revealed significant effects of age, sex, illness severity, neuromuscular disease, surgical approach, Medicaid status, and annual hospital volume on outcomes (P < 0.05). After controlling for these factors using multivariate regression, patients insured by Medicaid were found to have a significantly greater odds for complications (P = 0.017) and a significantly increased LOS (P < 0.001) compared with patients with all other sources of payment. Additionally, multivariate regression revealed an inverse relationship between annual hospital volume and likelihood of reoperation, as patients treated at hospitals with annual volumes of 5.1 to 25.0, 25.1 to 50.0, and greater than 50.0 spinal fusions all had approximately half the odds of reoperation (P = 0.042, P = 0.004, and P = 0.028 respectively) as patients treated at hospitals with an annual volume of 5.0 or fewer spinal fusions per year. The current data suggest that being insured with Medicaid in the state of California is associated with poorer outcomes after scoliosis surgery. Additionally, this study documents a volume/outcomes relationship in scoliosis surgery.
