Abstract
PURPOSE The purpose of this study is to identify risk factors for delays in planned total shoulder arthroplasty (TSA) and determine the perioperative outcomes of TSAs that experienced a delay. METHODS The American College of Surgeons National Quality Improvement Program (NSQIP) database was queried from 2006 to 2019 for primary TSA. Delayed TSA was defined as surgery that occurred greater than one day after hospital admission. Patient demographics, comorbidities, and post-operative complications were collected and compared; the incidence of delayed TSA was analyzed. RESULTS The delayed patients were older, had a higher BMI, a higher rate of recent prior major surgery, and more comorbidities. Delayed patients had higher rates of postoperative complications, return to the OR, and 30-day readmission. Between 2006 and 2019, the rate of delayed TSA decreased. CONCLUSION Surgeons should take care to ensure that patients with comorbidities undergo thorough preoperative clearance to prevent same-day cancellations and postoperative complications.

Goldfarb SI, Xu AL, Gupta A, Mun F, Durand WM, Gonzalez TA, Aiyer AA. How Have Patient Out-of-pocket Costs for Common Outpatient Orthopaedic Foot and Ankle Surgical Procedures Changed Over Time? A Retrospective Study From 2010 to 2020. Clin Orthop Relat Res 2024; 482:313-322. [PMID: 37498201 PMCID: PMC10776159 DOI: 10.1097/corr.0000000000002772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 06/14/2023] [Indexed: 07/28/2023]
Abstract
BACKGROUND Out-of-pocket (OOP) costs can be substantial financial burdens for patients and may even cause patients to delay or forgo necessary medical procedures. Although overall healthcare costs are rising in the United States, recent trends in patient OOP costs for foot and ankle orthopaedic surgical procedures have not been reported. Fully understanding patient OOP costs for common orthopaedic surgical procedures, such as those performed on the foot and ankle, might help patients and professionals make informed decisions regarding treatment options and demonstrate to policymakers the growing unaffordability of these procedures. QUESTIONS/PURPOSES (1) How do OOP costs for common outpatient foot and ankle surgical procedures for commercially insured patients compare between elective and trauma surgical procedures? (2) How do these OOP costs compare between patients enrolled in various insurance plan types? (3) How do these OOP costs compare between surgical procedures performed in hospital-based outpatient departments and ambulatory surgical centers (ASCs)? (4) How have these OOP costs changed over time? METHODS This was a retrospective, comparative study drawn from a large, longitudinally maintained database. Data on adult patients who underwent elective or trauma outpatient foot or ankle surgical procedures between 2010 and 2020 were extracted using the MarketScan Database, which contains well-delineated cost variables for all patient claims, which are particularly advantageous for assessing OOP costs. Of the 1,031,279 patient encounters initially identified, 41% (427,879) met the inclusion criteria. Demographic, procedural, and financial data were recorded. The median patient age was 50 years (IQR 39 to 57); 65% were women, and more than half of patients were enrolled in preferred provider organization insurance plans. Approximately 75% of surgical procedures were classified as elective (rather than trauma), and 69% of procedures were performed in hospital-based outpatient departments (rather than ASCs). The primary outcome was OOP costs incurred by the patient, which were defined as the sum of the deductible, coinsurance, and copayment paid for each episode of care. Monetary data were adjusted to 2020 USD. A general linear regression, the Kruskal-Wallis test, and the Wilcoxon-Mann-Whitney test were used for analysis, as appropriate. Alpha was set at 0.05. RESULTS For foot and ankle indications, trauma surgical procedures generated higher median OOP costs than elective procedures (USD 942 [IQR USD 150 to 2052] versus USD 568 [IQR USD 51 to 1426], difference of medians USD 374; p < 0.001). Of the insurance plans studied, high-deductible health plans had the highest median OOP costs. OOP costs were lower for procedures performed in ASCs than in hospital-based outpatient departments (USD 645 [IQR USD 114 to 1447] versus USD 681 [IQR USD 64 to 1683], difference of medians USD 36; p < 0.001). This trend was driven by higher coinsurance for hospital-based outpatient departments than for ASCs (USD 391 [IQR USD 0 to 1136] versus USD 337 [IQR USD 0 to 797], difference of medians USD 54; p < 0.001). The median OOP costs for common outpatient foot and ankle surgical procedures increased by 102%, from USD 450 in 2010 to USD 907 in 2020. CONCLUSION Rapidly increasing OOP costs of common foot and ankle orthopaedic surgical procedures warrant a thorough investigation of potential cost-saving strategies and initiatives to enhance healthcare affordability for patients. In particular, measures should be taken to reduce underuse of necessary care for patients enrolled in high-deductible health plans, such as shorter-term deductible timespans and placing additional regulations on the implementation of these plans. Moreover, policymakers and physicians could consider finding ways to increase the proportion of procedures performed at ASCs for procedure types that have been shown to be equally safe and effective as in hospital-based outpatient departments. Future studies should extend this analysis to publicly insured patients and further investigate the health and financial effects of high-deductible health plans and ASCs, respectively. LEVEL OF EVIDENCE Level III, economic and decision analysis.

[PMID: 36972856 DOI: 10.1016/j.arth.2023.03.058] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 03/13/2023] [Accepted: 03/19/2023] [Indexed: 03/29/2023] Open
Abstract
BACKGROUND Understanding mark-up ratios (MRs), the ratio between a healthcare institution's submitted charge and the Medicare payment received, for high-volume orthopaedic procedures is imperative to inform policy about price transparency and reducing surprise billing. This analysis examined the MRs for primary and revision total hip and knee arthroplasty (THA and TKA) services to Medicare beneficiaries between 2013 and 2019 across healthcare settings and geographic regions. METHODS A large dataset was queried for all THA and TKA procedures performed by orthopaedic surgeons between 2013 and 2019, using Healthcare Common Procedure Coding System (HCPCS) codes for the most frequently used services. Yearly MRs, service counts, average submitted charges, average allowed payments, and average Medicare payments were analyzed. Trends in MRs were assessed. We evaluated 9 THA HCPCS codes, averaging 159,297 procedures a year provided by a mean of 5,330 surgeons. We evaluated 6 TKA HCPCS codes, averaging 290,244 procedures a year provided by a mean of 7,308 surgeons. RESULTS For knee arthroplasty procedures, a decrease was noted for HCPCS code 27438 (patellar arthroplasty with prosthesis) over the study period (8.30 to 6.62; P = .016) and HCPCS code 27447 (TKA) had the highest median (interquartile range [IQR]) MR (4.73 [3.64 to 6.30]). For revision knee procedures, the highest median (IQR) MR was for HCPCS code 27488 (removal of knee prosthesis; 6.12 [3.83-8.22]). While no trends were noted for both primary and revision hip arthroplasty, median (IQR) MRs in 2019 for primary hip procedures ranged from 3.83 (hemiarthroplasty) to 5.06 (conversion of previous hip surgery to THA) and HCPCS code 27130 (total hip arthroplasty) had a median (IQR) MR of 4.66 (3.58-6.44). For revision hip procedures, MRs ranged from 3.79 (open treatment of femoral fracture or prosthetic arthroplasty) to 6.10 (revision of THA femoral component). Wisconsin had the highest median MR by state (>9) for primary knee, revision knee, and primary hip procedures. CONCLUSION The MRs for primary and revision THA and TKA procedures were strikingly high, as compared to nonorthopaedic procedures. These findings represent high levels of excess charges billed, which may pose serious financial burdens to patients and must be taken into consideration in future policy discussions to avoid price inflation.

Abstract
INTRODUCTION Out-of-pocket (OOP) costs for medical and surgical care can result in substantial financial burden for patients and families. Relatively little is known regarding OOP costs for commercially insured patients receiving orthopaedic surgery. The aim of this study is to analyze the trends in OOP costs for common, elective orthopaedic surgeries performed in the hospital inpatient setting. METHODS This study used an employer-sponsored insurance claims database to analyze billing data of commercially insured patients who underwent elective orthopaedic surgery between 2014 and 2019. Patients who received single-level anterior cervical diskectomy and fusion (ACDF), single-level posterior lumbar fusion (PLF), total knee arthroplasty (TKA), and total hip arthroplasty (THA) were identified. OOP costs associated with the surgical episode were calculated as the sum of deductible payments, copayments, and coinsurance. Monetary data were adjusted to 2019 dollars. General linear regression, Wilcoxon-Mann-Whitney, and Kruskal-Wallis tests were used for analysis, as appropriate. RESULTS In total, 10,225 ACDF, 28,841 PLF, 70,815 THA, and 108,940 TKA patients were analyzed. Most patients in our study sample had preferred provider organization insurance plans (ACDF 70.3%, PLF 66.9%, THA 66.2%, and TKA 67.0%). The mean OOP costs for patients, by procedure, were as follows: ACDF $3,180 (SD = 2,495), PLF $3,166 (SD = 2,529), THA $2,884 (SD = 2,100), and TKA $2,733 (SD = 1,994). Total OOP costs increased significantly from 2014 to 2019 for all procedures (P < 0.0001). Among the insurance plans examined, patients with high-deductible health plans had the highest episodic OOP costs. The ratio of patient contribution (OOP costs) to total insurer contribution (payments from insurers to providers) was 0.07 for ACDF, 0.04 for PLF, 0.07 for THA, and 0.07 for TKA. CONCLUSION Among commercially insured patients who underwent elective spinal fusion and major lower extremity joint arthroplasty surgery, OOP costs increased from 2014 to 2019. The OOP costs for elective orthopaedic surgery represent a substantial and increasing financial burden for patients.

Abstract
STUDY DESIGN Retrospective database review. OBJECTIVES The incidence and risk factors for surgical delay of multilevel spine fusion for adult spinal deformity (ASD), and the complications corresponding therewith, remain unknown. The objectives of this study are to assess the incidence and risk factors for unexpected delay of elective multilevel spinal fusions on the date of surgery as well as the postoperative complications associated with these delays. METHODS We conducted a retrospective review of the ACS-NSQIP database on patients undergoing elective spinal instrumentation of greater than 7 levels for ASD between the years 2005 and 2015. Preoperative risk factors for delay and postoperative complications were compared between the cohorts of patients with and without surgical delays. RESULTS Multivariate analysis of 1570 (15.6%) patients identified advanced age, male sex, American Society of Anesthesiologists (ASA) Class 4, and history of smoking as independent risk factors for delay. Patients experiencing surgical delay demonstrated longer operative times, increased intraoperative bleeding, longer hospitalizations, and significantly higher rates of postoperative complications. Patients experiencing delay demonstrated an almost 7-fold increase in mortality rate (3.4% vs 0.5%, P < .001). CONCLUSIONS Delays in elective surgical care for spinal deformity are negatively related to patient outcomes. Advanced age, male sex, increased ASA class, and a history of smoking cigarettes place patients at risk for surgical delay of multilevel spinal fusion. Patients experiencing surgical delay are at higher risk for postoperative complications, including a 7-fold increase in mortality. These findings suggest that ASD surgery should be postponed in patients experiencing a delay, until modifiable risk factors can be medically optimized, and perhaps postponed indefinitely in those with nonmodifiable risk factors.

Preoperative and Perioperative Predictors of Length of Hospital Stay after Primary Total Hip Arthroplasty-Our Experience on 743 Cases. J Clin Med 2021; 10:jcm10215053. [PMID: 34768573 PMCID: PMC8584853 DOI: 10.3390/jcm10215053] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/21/2021] [Accepted: 10/26/2021] [Indexed: 12/17/2022] Open
Abstract
The aim of this retrospective investigation is to evaluate the correlation between several preoperative and perioperative factors and the length of hospital stay in patients that underwent elective total hip arthroplasty with overnight admission. Medical records of patients that underwent THA from the beginning of 2016 to the end of 2018 were retrospectively screened. Demographics, comorbidities, whole blood count, intraoperative details, and length of postoperative stay were retrieved. The association between clinical, laboratory and surgical factors and the length of hospital stay was explored by means of negative binomial and logistic regression models. The median length of postoperative hospital stay was four days (Inter Quartile Range, IQR 3, 5). After univariate regression a stepwise multivariate regression showed that operative time (p = 0.001), the preoperative serum creatinine (p < 0.001), the intraoperative blood loss (p = 0.04) and the use of an anterolateral approach (p < 0.001) were found to correlate significantly with the increase of the hospitalization length, while no significant correlation was found for all the other features. Multivariable model fitted through logistic regression (LOS below or over the median value of four days) had an Area Under the Curve (AUC) of 0.748. Our analysis suggests a significant role played by different preoperative and perioperative variables in influencing the length of hospital stay.

Abstract
BACKGROUND Readmission following total joint arthroplasty has become a closely watched metric for many hospitals in the United States due to financial penalties imposed by Centers for Medicare and Medicaid Services. The purpose of this study was to identify both preoperative and postoperative reasons for readmission within 30 days following primary total hip and total knee arthroplasty (TKA). METHODS Retrospective data were collected for patients who underwent elective primary total hip arthroplasty (THA; CPT code 27130) and TKA (27447) from 2008 to 2013 at our institution. The sample was separated into readmitted and nonreadmitted cohorts. Demography, comorbidities, Charlson comorbidity index (CCI), operative parameters, readmission rates, and causes of readmission were compared between the groups using univariate and multivariate regression analysis. RESULTS There were 42 (3.4%) and 28 (2.2%) readmissions within 30 days for THA and TKA, respectively. The most common cause of readmission within 30 days following total joint arthroplasty was infection. Trauma was the second most common reason for readmission of a THA while wound dehiscence was the second most common cause for readmission following TKA. With univariate regression, there were multiple associated factors for readmission among THA and TKA patients, including body mass index, metabolic equivalent (MET), and CCI. Multivariate regression revealed that hospital length of stay was significantly associated with 30-day readmission after THA and TKA. CONCLUSION Patient comorbidities and preoperative functional capacity significantly affect 30-day readmission rate following total joint arthroplasty. Adjustments for these parameters should be considered and we recommend the use of CCI and METs in risk adjustment models that use 30-day readmission as a marker for quality of patient care.

Abstract
Aims The aim of this study was to determine the impact of the severity of anaemia on postoperative complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Methods A retrospective cohort study was conducted using the American College of Surgeons National Quality Improvement Program (ACS-NSQIP) database. All patients who underwent primary TKA or THA between January 2012 and December 2017 were identified and stratified based upon hematocrit level. In this analysis, we defined anaemia as packed cell volume (Hct) < 36% for women and < 39% for men, and further stratified anaemia as mild anaemia (Hct 33% to 36% for women, Hct 33% to 39% for men), and moderate to severe (Hct < 33% for both men and women). Univariate and multivariate analyses were used to evaluate the incidence of multiple adverse events within 30 days of arthroplasty. Results Following adjustment, patients in the THA cohort with moderate to severe anaemia had an increased odds of 6.194 (95% confidence interval (CI) 5.679 to 6.756; p < 0.001) for developing any postoperative complication. Following adjustment, patients in the TKA cohort with moderate to severe anaemia had an increased odds of 5.186 (95% CI 4.811 to 5.590; p < 0.001) for developing any postoperative complication. Among both cohorts, as severity increased, there was an increased risk of postoperative complications. Conclusion Preoperative anaemia is a risk factor for complications following primary arthroplasty. There is a significant relationship between the severity of anaemia and the odds of postoperative complications. Patients who had moderate to severe anaemia were at increased risk of developing postoperative complications relative to patients with mild anaemia. When considering elective primary THA or TKA in a moderately or severely anaemic patient, surgeons should strongly consider correcting anaemia prior to surgery if possible.

Abstract
BACKGROUND With recent Medicare payment changes, older adults are increasingly likely to be discharged home instead of to extended care facilities after total joint arthroplasty (TJA), and may therefore be at increased risk for readmissions. Identifying risk factors for readmission could help re-align care pathways for vulnerable patients; recent research has suggested preoperative dependency in activities of daily living (ADL) may increase perioperative and postoperative surgical complications. However, the proportion of older surgical patients with ADL dependence before TJA, and the impact of ADL dependency on the frequency and timing of hospital readmissions is unknown. QUESTIONS/PURPOSES (1) What proportion of older adults discharged home after TJA have preoperative ADL dependency? (2) Is preoperative ADL dependency associated with increased risk of hospital readmissions at 30 days or 90 days for older adults discharged home after TJA? METHODS This was a retrospective cohort analysis of 6270 Medicare fee-for-service claims from 2012 from a 5% national Medicare sample for older adults (older than 65 years) receiving home health care after being discharged to the community after elective TJA. Medicare home health claims were used for two reasons: (1) the primary population of interest was older adults and (2) the accompanying patient-level assessment data included an assessment of prior dependency on four ADL tasks. Activities of daily living dependency was dichotomized as severe (requiring human assistance with all four assessed tasks) or partial/none (needing assistance with three or fewer ADLs); this cutoff has been used in prior research to evaluate readmission risk. Multivariable logistic regression models, clustered at the hospital level and adjusted for known readmission risk factors (such as comorbidity status or age), were used to model the odds of 30- and 90- day and readmission for patients with severe ADL dependence. RESULTS Overall, 411 patients were hospitalized during the study period. Of all readmissions, 64% (262 of 411) occurred within the first 30 days, with a median (interquartile range [IQR]) time to readmission of 17 days (5 to 46). Severe ADL dependency before surgery was common for older home health recipients recovering from TJA, affecting 17% (1066 of 6270) of our sample population. After adjusting for clinical covariates, severe ADL dependency was not associated with readmissions at 90 days (adjusted odds ratio = 1.20 [95% CI 0.93 to 1.55]; p = 0.15). However, severe preoperative ADL dependency was associated with higher odds of readmission at 30 days (adjusted OR = 1.45 [95% CI 1.11 to 1.99]; p = 0.008). CONCLUSIONS Severe preoperative ADL dependency is modestly associated with early but not late hospital readmission after TJA. This work demonstrates that it may important to apply a simple screening of ADL dependency preoperatively so that surgeons can guide changes in care planning for older adults undergoing TJA, which may include participation in preoperative rehabilitation (pre-habilitation) or more aggressive follow-up in the 30 days after surgery. Further research is needed to determine whether severe ADL dependence can be modified before surgery, and whether these changes in dependency can reduce readmission risk after TJA.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) is well-tolerated by most patients and commonly necessitates only a short hospital admission. Surgical delay after hospital admission, however, may result in longer hospital stays, consequently increasing hospital resource utilization. The current study evaluates risk factors for surgical delay in patients undergoing elective ACDF. METHODS A retrospective analysis of ACS-NSQIP data from 2006-2015 was performed. Patients undergoing elective ACDF were selected using current procedural terminology (CPT) codes (22251, 22252, 22554). A surgical delay was defined as surgery that occurred one day or later after initial hospital admission. Differences in outcomes between the non-delayed and delayed cohorts were evaluated with univariate analysis. Multivariate logistic regression was performed to identify risk factors for surgical delay. RESULTS There were a total of 771 (2.0%) surgical delays out of 39,371 patients undergoing elective ACDF from 2006-2015. Multivariate analysis found partially dependent functional status (OR 5.88; 95% CI: 4.48-7.71; P<0.001), totally dependent functional status (OR 18.22; 95% CI: 9.60-34.59; P<0.001), ASA class 4 (OR 2.73; 95% CI: 1.70-4.38; P<0.001), bleeding disorders (OR 1.75; 95% CI: 1.08-2.85; P=0.024), male sex (OR 1.19; 95% CI: 1.03-1.38; P=0.019), and chronic steroid use (OR 1.76; 95% CI: 1.30-2.37; P<0.001) as independent predictors of delay. Univariate analysis found surgical delay was associated with a higher rate of post-operative major adverse events (4.8% vs. 1.1%; P<0.001), mortality (1.0% vs. 0.2%; P<0.001) and greater than five-fold increase in total length of stay (9.52 vs. 1.65 days; P<0.001). CONCLUSIONS Impaired pre-operative functional status, a higher comorbidity burden, and chronic steroid use are risk factors for surgical delay, increased complications, and length of stay in patients undergoing elective ACDF. This is helpful information to consider given a rising incidence of cervical fusions in the Medicare population, a wide variation in costs, and increasing popularity of bundled-payment models.

Dependent Functional Status is a Risk Factor for Perioperative and Postoperative Complications After Total Hip Arthroplasty. J Arthroplasty 2019; 34:S348-S351. [PMID: 30685262 DOI: 10.1016/j.arth.2018.12.037] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 12/12/2018] [Accepted: 12/30/2018] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND As the population ages, the need for total hip arthroplasty (THA) will increase. However, this will be associated with an increase in comorbidities and a decrease in the ability to independently perform activities of daily living (ADLs). This study was designed to evaluate the impact preoperative functional status has on short-term outcomes after THA. METHODS Primary THAs performed from 2012 to 2016 were identified in the National Surgical Quality Improvement Program database. Final analysis included 115,590 cases. Patients who could perform all ADLs were classified as independent functional status (n = 113,436), and patients requiring assistance with ADLs were classified as dependent functional status (n = 2154). Univariate analysis was used to compare perioperative outcomes and 30-day complication rates. Multivariate regression was then applied to determine if preoperative dependent functional status was an independent risk factor for adverse outcomes. RESULTS Functionally dependent patients were more likely to experience operative times >120 minutes (odds ratio [OR] = 1.39; P < .001), hospital stays >10 days (OR = 2.96; P < .001), and nonhome discharge (OR = 2.53; P < .001). Dependent functional status was also an independent risk factor for mortality (OR = 3.00; P = .001), reoperation (OR = 1.39; P = .015), readmission (OR = 1.75; P < .001), superficial surgical site infection (OR = 1.96; P = .002), wound dehiscence (OR = 2.72; P = .034), pneumonia (OR = 2.16; P = .001), reintubation (OR = 2.31; P = .007), prolonged ventilator use (OR = 3.01; P = .009), renal failure necessitating dialysis (OR = 3.94; P = .002), urinary tract infection (OR = 1.78; P = .001), blood transfusion (OR = 1.75; P < .001), and sepsis (OR = 2.38; P = .001). CONCLUSIONS Functionally dependent patients undergoing THA are at higher risk of mortality, adverse perioperative outcomes, and complications. These data may aid for patient counseling and risk stratification.

Abstract
INTRODUCTION No known study has compared the predictive power of the American Society of Anesthesiologists (ASA) class, modified Charlson Comorbidity Index, modified Frailty Index, and demographic characteristics for general health complications after total hip arthroplasty (THA). METHODS Comorbidity indices and demographics from National Surgical Quality Improvement Program THA patients were evaluated for discriminative ability in predicting adverse outcomes using the area under the curve analysis from the receiver operating characteristic curves. Perioperative outcomes included any adverse event, severe adverse events, minor adverse events, extended hospital stay, and discharge to higher-level care. RESULTS In total, 64,792 THA patients were identified. The most predictive comorbidity index was ASA, and demographic factor was age. Of these, age had the greatest discriminative ability for four of the five adverse outcomes. CONCLUSION For THA, easily obtained patient ASA and age are more predictive of perioperative adverse outcomes than the more complex and numerically tabulated modified Charlson Comorbidity Index and modified Frailty Index.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE To assess the incidence of and risk factors for delay of elective lumbar fusion surgery, as well as medical and surgical complications associated with surgical delay. SUMMARY OF BACKGROUND DATA Lumbar fusion is a well-established treatment for patients with degenerative spondylolisthesis with stenosis who have failed conservative management. Rarely, patients admitted for elective lumbar fusion may experience a delay in surgery past the day of admission. The incidence of, and risk factors for, delay of elective lumbar fusion surgery and the complications associated therewith have never been previously evaluated. METHODS We retrospectively reviewed the ACS-NSQIP registry utilizing Current Procedural Terminology (CPT) codes 22612, 22558, 22630, and 22633 to identify all patients undergoing a single level spinal fusion. The data were then subdivided into cohorts consisting of patients with and without surgical delay. Demographic information, preoperative risk factors for delay, as well as intraoperative and postoperative complications were compared between the groups. RESULTS We identified 2758 (5.46%) patients as experiencing a delay before lumbar fusion. Multivariate analysis was then performed and identified male sex, American Society of Anesthesiologists classes 3 and 4, and chronic steroid use as risk factors increasing the rate of surgical delay. Multiple complication rates were also significantly higher in the delayed group, including an almost 10-fold increase in mortality rate (0.2% vs. 1.9%, respectively, P < 0.001). CONCLUSION Delays in elective surgery can affect medical system resource utilization, increasing costs and leading to worse patient outcomes. Patients with chronic steroid use and higher American Society of Anesthesiologists class may be at risk for surgical delay in lumbar fusion beyond the day of admission, and are at increased risk for significant complications postoperatively. Thorough medical evaluation and preoperative optimization may be indicated for these patients. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND The purpose of this study is to (1) identify the incidence of surgical delay in hip fractures, (2) evaluate the time point surgical delay puts patients at increased risk for complications, and (3) identify risk factors for surgical delay in the setting of surgical management of hip fractures. METHODS A multi-center database was queried for patients of 60 years of age or older undergoing surgical treatment of a hip fracture. Surgical delay was defined by days from admission until surgical intervention. Univariate analyses and multivariate analyses were performed on all groups. RESULTS A total of 4215 patients underwent surgery for their hip fracture. Of those experiencing surgical delay, 3304 (78%) patients experienced surgical delay of ≥1 day, 1314 (31%) had delay of ≥2 days, and 480 (11%) experienced delay of ≥3 days. There was a significant difference in complications if patients experienced surgical delay of ≥2 days (P ≤ .01). Multivariate analyses identified multiple risk factors for delay of ≥2 days including congestive heart failure (odds ratio 3.09, 95% confidence interval 2.04-4.66) and body mass index ≥40 (odds ratio 2.31, 95% confidence interval 1.31-4.08). Subgroup analysis identified that patients undergoing total hip arthroplasty were not at risk for complications with surgical delay of ≥2 days. CONCLUSION Surgical delay of ≥2 days in the setting of hip fractures is common and confers an increased risk of complications in those undergoing non-total hip arthroplasty procedures. We recommend surgical intervention prior to 48 hours from hospital admission when possible. Healthcare systems can utilize our non-modifiable risk factors when performing quality assessment and cost accounting.

Abstract
BACKGROUND Total joint arthroplasty is a proven treatment for osteoarthritis of the knee and hip that has failed conservative treatment. While most of total joint arthroplasty is considered elective with surgery on the day of admission, a small subset of patients may require delay in surgery past the day of admission. Recently, surgical delay for primary total knee arthroplasty has been identified. However, the incidence, outcomes, and risk factors for delay in surgery before total hip arthroplasty (THA) have not been previously defined. QUESTIONS/PURPOSE In patients undergoing THA, we sought to define (1) the incidence of and risk factors for delay in surgery, (2) the postoperative complications between surgical delay and no surgical delay cohorts, and (3) association of the Charlson comorbidity index (CCI) in patients with delay of surgery. METHODS We retrospectively queried the National Surgical Quality Improvement Program database using Current Procedural Terminology billing codes and identified 7890 THAs performed between 2006 and 2010. Univariate and subsequent multivariate logistic regression analysis were then used to identify risk factors for surgical delay. Correlation between CCI and surgical delay in THA was evaluated. RESULTS One-hundred seventy-nine patients (2.31%) were identified as experiencing a surgical delay before THA. Multivariate analysis identified congestive heart failure (CHF) (P = .0038), bleeding disorder (P < .0001), sepsis (P < .0001), prior operation in past 30 days (P = .0001), dependent functional status (P < .0001), American Society of Anesthesiologists class 3 (P = .0001), American Society of Anesthesiologists class 4 (P = .0023), significant weight loss (P = .0109), and hematocrit <38% (P < .0001) as independent risk factors for delay in surgery. Compared with the nondelay cohort, those experiencing surgical delay before THA had higher rates of postoperative surgical (8.9% vs 3.1%, P < .0001) and medical complications (23.5% vs 10.1%, P < .0001). Mean CCI was higher in the THA surgical delay cohort (3.16 vs 2.24, P < .0001) compared with the nondelay group. CONCLUSION Surgical delay in patients undergoing THA may cause undue disruption in surgeon and hospital resource utilization. In an era of quality assessment and cost consciousness, it is important to understand that the short-term outcomes of elective, same day THA differ dramatically from those hospitalized for medical necessity before surgery. Surgeons should consider thorough medical evaluation in those with CHF, bleeding disorders, sepsis, significant weight loss, and hematocrit <38% before hospital admission.
