The Association between Race and Extended Length of Stay in Low-energy Proximal Humerus Fractures in Elderly Patients.

INTRODUCTION: Proximal humerus fractures (PHFs) are one of the most common fractures among patients aged 65 years and older, commonly due to low-energy mechanisms. It is essential to identify drivers of increased healthcare utilization in geriatric PHF patients and bring awareness to any disparities in care. Here, we identify factors associated with the likelihood of inpatient admission and prolonged hospital stay among patients aged 65 years and older who sustain PHF due to falls. METHODS: A national database was used to identify patients aged 65 years and older who suffered proximal humeral fractures due to a fall. Patient factors were analyzed for association with the likelihood of admission and odds of prolonged stay (≥5 days). RESULTS: In the study period, 75,385 PHF patients who met our inclusion criteria presented to the emergency department and 14,118 (18.7%) were admitted. Black race was significantly associated with decreased odds of admission ( P < 0.001) and increased likelihood of prolonged stay ( P = 0.007) compared with White patients. Patients aged 75 to 84 and 85+ were both more likely to be admitted ( P < 0.001) and experienced a prolonged hospital stay ( P = 0.015). Patients undergoing surgical intervention with reverse total shoulder arthroplasty were associated with admission and prolonged length of stay ( P < 0.001). Hospitals in Midwestern ( P < 0.001) and Western ( P < 0.001) regions exhibited lower rates of admission and Northeastern hospitals were associated with prolonged stays ( P = 0.001). Finally, trauma and nonmetropolitan ( P < 0.001) centers were associated with admission. CONCLUSION: Our study highlights the notable influence of age and race on the likelihood of hospital admission and prolonged hospital stay. Specifically, Black patients exhibited prolonged hospital stay, which has been associated with lower-quality care, warranting additional exploration. Understanding these demographic and hospital-related factors is essential for optimizing resource allocation and reducing healthcare disparities in the care of PHF patients, especially as the population ages and the incidence of PHF continues to rise.

Can You Pay Your Way to Readership? Free to Publish Open Access Formats Receive Greater Readership and Citations Than Paid Open Access Formats in Total Knee Arthroplasty Literature.

BACKGROUND: As publishing with open access is becoming increasingly popular within orthopaedics, understanding the types of publishing options available and what each may deliver is critically important. Hybrid articles require a high article processing charge. Open journal articles have a lower fee, while closed license articles are freely accessible at no charge. Open repository articles are peer-reviewed manuscripts posted freely online. The purpose of this study was to determine the relationship between article type and resulting citations, social media attention, and readership in total knee arthroplasty (TKA) literature. METHODS: Open access TKA journal articles published since 2016 were found using the Altmetric Explorer Database. Data gathered included the Altmetric Attention Score (attention), Mendeley Readership Score (readership), and citations per article. Articles were grouped by type: open journal, hybrid, closed license, and open repository. Results were analyzed using descriptive statistics and Tukey's analysis; α = 0.05. RESULTS: A total of 9,606 publications were included. The open repository had the greatest mean citations (14.40), while open journal (9.55) had fewer than all other categories (P < .001). Hybrid had the greatest mean attention (10.35), and open journal (6.16) had a lower mean attention than all other categories (P ≤ .002). Open repository had the greatest mean readership (44.68), and open journal (34.00) had a lower mean readership than all other categories (P ≤ .012). The mean publication fee for paid publication options was $1,792 United States dollars. CONCLUSIONS: In open access TKA literature, free-to-publish open repositories had the greatest mean citations and readership. Free publication options, open repositories and closed licenses, had greater readership compared to paid publication options.

Using a Modern Linked Research Database to Examine Gender Disparities in Orthopaedic Grant Funding from 2010 to 2022.

BACKGROUND: Gender disparities in research grant funding persist in many disciplines. With use of the Dimensions database, we sought to examine the extent of gender disparities in U.S. orthopaedic grant funding from 2010 onward. Our aim was to provide insights into the extent of gender disparities in the field of orthopaedic research and to highlight the potential need for future action to address these disparities. METHODS: Using orthopaedic-related search terms, we queried all U.S. grants awarded for orthopaedic research from 2010 to 2022. A total of 22,326 results were then manually screened to exclude those without a direct focus on orthopaedic research. The amounts received per principal investigator were reported in U.S. dollars and adjusted for inflation. Author gender was predicted with use of the Genderize.io algorithm application programming interface. The iCite Relative Citation Ratio (RCR) was utilized to assess the impact of the publications linked to each grant. RESULTS: A total of 1,723 grants were included. Men principal investigators received significantly higher median funding per grant in 2011, 2012, and 2013; however, this trend reversed with women receiving nonsignificantly higher funding in 2015, 2017, 2018, 2021, and 2022. In 2020, women received significantly higher median funding per grant than men ($166,234 versus $121,384; p = 0.04). Throughout the 13-year period, men principal investigators accounted for approximately 71% of grants, with a very weak increasing trend in the percent of grants attributed to women (R 2 = 0.16; p < 0.001). Grants with men principal investigators resulted in more publications than those with women principal investigators (mean publications, 11.1 versus 6.6; p = 0.001). Publications resulting from grants awarded to men had a significantly higher mean RCR than those resulting from grants awarded to women (2.42 versus 2.09; p = 0.04). CONCLUSIONS: There was no significant difference in the median amounts of funding per grant awarded to men and to women in 7 of the past 8 years, despite significantly greater funding per grant having been awarded to men from 2011 to 2013. Men principal investigators accounted for the majority of grants received during the study period, although this proportion was lower than the proportion of men among orthopaedic surgeons in 2022. This study could inform initiatives aimed at promoting equity in grant funding for orthopaedic research.

Barriers to Entry: Socioeconomic Discrepancies Between Unmatched First-Time Applicants and Reapplicants in the Field of Orthopaedic Surgery.

INTRODUCTION: Orthopaedic surgery remains a competitive surgical subspecialty with more applicants than spots each year. As a result, numerous students fail to match into these competitive positions each year with a growing number of reapplicants in consecutive application cycles. We sought to understand the socioeconomic factors at play between this growing reapplicant pool compared with first-time applicants to better understand potential discrepancies between these groups. Our hypothesis is that reapplicants would have higher socioeconomic status and have less underrepresented minority representation compared with successful first-time applicants. METHODS: A retrospective review of deidentified individual orthopaedic surgery applicant data from the American Association of Medical Colleges was reviewed from 2011 to 2021. Individual demographic and application data as well as self-reported socioeconomic and parental data were analyzed using descriptive and advanced statistics. RESULTS: Of the 12,112 applicants included in this data set, 77% were first-time applicants (61% versus 17% successfully entered into an orthopaedic surgery residency vs versus unmatched, respectively), whereas 22% were reapplicants. In successful first-time applicants, 12% identified as underrepresented minorities in medicine. The proportion of underrepresented minorities was significantly higher among unmatched first-time applicants (20%) and reapplicants (25%) ( P < 0.001). Reapplicants (mean = $83,364) and unmatched first-time applicants (mean = $80,174) had less medical school debt compared with first time applicants (mean = $101,663) ( P < 0.001). More than 21% of reapplicants were found to have parents in healthcare fields, whereas only 16% of successful first-time applicants and 15% of unsuccessful first-applicants had parents in health care ( P < 0.001). CONCLUSIONS: Reapplicants to orthopaedic surgery residency have less educational debt and are more likely to have parental figures in a healthcare field compared with first-time applicants. This suggests the discrepancies in socioeconomic status between reapplicants and first-time applicants and the importance of providing resources for reapplicants.

Geographic Variation in Physician Payments from Private Insurers for Commonly Performed Inpatient Orthopaedic Surgeries in the United States.

We investigated geographic variation in percentage of private insurance payments to United States physicians for commonly performed orthopaedic procedures. We queried a private administrative claims database for patients who underwent inpatient total knee arthroplasty (TKA), total hip arthroplasty (THA), single-level anterior cervical discectomy and fusion (ACDF), and posterior lumbar fusion (PLF) from 2010 to 2017. Percentage of total payments to physician (PPP) was calculated by dividing physician payments by total payments. Analysis of variance was used to determine geographic differences in PPP. A total of 542,530 patients were included, mean age was 55 ± 8. PPP significantly varied between states for all four procedures (p < 0.001); Colorado and Alabama had the lowest and highest PPP, respectively. There was a significant annual decrease in PPP across all regions in all procedures. There was significant variation in percentage of total payments to physicians across geographic regions in the United States for TKA, THA, ACDF and PLF.

Health Care Resource Utilization in Commercially Insured Patients Undergoing Anterior Cervical Discectomy and Fusion for Degenerative Cervical Pathology.

STUDY DESIGN: Retrospective review of an administrative database. OBJECTIVES: The aim of our study was to investigate the distribution of spending for the entire episode of care among nonelderly, commercially insured patients undergoing elective, inpatient anterior cervical discectomy and fusion (ACDF) surgeries for degenerative cervical pathology. METHODS: Using a private insurance claims database, we identified patients who underwent single-level, inpatient ACDF for degenerative spinal disease. Patients were selected using a combination of Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes. Entire episode of care was defined as 6-months before (preoperative) to 6 months after (postoperative) the surgical admission. RESULTS: In our cohort containing 33 209 patients, perioperative median spending per patient (MSPP) within the year encompassing surgery totaled $37 020 (interquartile range [IQR] $28 363-$49 206), with preoperative, surgical admission, and postoperative spending accounting for 9.8%, 80.7%, and 9.5% of total spending, respectively. Preoperatively, MSPP was $3109 (IQR $1806-$5215), 48% of patients underwent physical therapy, and 31% underwent injections in the 6 months period prior to surgery. Postoperatively, MSPP was $1416 (IQR $398-$3962), and unplanned hospital readmission (6% incidence) accounted for 33% of the overall postoperative spending. Discharge to a nonhome discharge disposition was associated with higher postoperative spending ($14 216) compared with patients discharged home ($1468) and home with home care ($2903), P < .001. CONCLUSION: Understanding the elements and distribution of perioperative spending for the episode of care in patients undergoing ACDF surgery for degenerative conditions is important for health care planning and resource allocation.

Preoperative and Postoperative Spending Among Working-Age Adults Undergoing Posterior Spinal Fusion Surgery for Degenerative Disease.

OBJECTIVE: To investigate the health care resource utilization and the associated 6 months preoperative and 6 months postoperative spending among patients undergoing posterior lumbar fusion. METHODS: We retrospectively reviewed a private insurance claims database for patients who underwent single-level posterior spinal fusion from January 2011 to December 2015. Outpatient health services, prescription pain medications, and inpatient admissions were assessed. RESULTS: Among 25,401 patients (mean age, 52 years; 58% female) in the final cohort, median spending during the period from 6 months before surgery to 6 months after surgery was $60,714 (interquartile range [IQR], $46,961-$79,892)/patient. Preoperative spending accounted for 7% ($121 million) of the total costs, and postoperative spending accounted for 8% ($135 million). Median preoperative spending was $3566 (IQR, $2144-$5857) per patient, with imaging accounting for the highest proportion (33%) of preoperative spending. In the 6 months period preceding surgery, 46% patients received injections and 47% received physical therapy. The median postoperative spending was $1954/patient (IQR, $735-$4416). Total postoperative spending was significantly higher among those not discharged home (median, $7525; IQR, $6779-$19,602) compared with those discharged home (median, $1617/patient; IQR, $648-$4033) and home with home care services (median, $2921; IQR, $1406-$5662) (P < 0.001). CONCLUSIONS: Unplanned readmission after posterior spinal fusion was the highest contributor to postoperative spending and the second highest contributor to overall costs. Understanding factors that contribute to the costs in the preoperative and postoperative period in patients undergoing single-level posterior lumbar fusion for degenerative pathology is essential to identify targets for cost containment.

Factors associated with extended length of stay in patients undergoing posterior spinal fusion for adolescent idiopathic scoliosis.

STUDY DESIGN: Cross-sectional study. OBJECTIVES: To investigate whether certain patient, surgical, and recovery-related factors may be associated with extended LOS following posterior spinal fusion for Adolescent Idiopathic Scoliosis (AIS). Understanding determinants of hospital length of stay (LOS) following surgical procedures is important for perioperative planning and improvements in quality of care. METHODS: Using a private insurance claims database, AIS patients ages 10-21 that underwent posterior spinal fusion from 2010 to 2016 in the United States were identified. Extended LOS was defined as > 7.2 days (+ 1 standard deviation from the mean). Univariate and multivariate analyses were performed to identify factors associated with extended LOS. Significance was set at p < 0.05. RESULTS: 5864 patients met the inclusion criteria (mean age 14.4 ± 2.2 years; 75% girls). Mean LOS was 4.7 ± 2.5 days (median 4 days). 69% patients had 7-12 levels fused, and 25% had 13+ levels fused. On multivariate analysis, factors associated with extended LOS were: longer fusion construct (13+ levels fused) (OR 2.1, p = 0.020), thoracoplasty (OR 3.8, p < 0.001), and postoperative complications: wound problems (OR 13, p < 0.001), respiratory problems (OR 7.9, p < 0.001), urinary tract infection (OR 6.0, p < 0.001), and constipation (OR 2.4, p < 0.001). Postoperative ICU admission, female gender, and surgery performed on Wednesday were significant on univariate analysis but not on multivariate analysis. Extended LOS was associated with an increase of $50,494 in net hospital payments (p < 0.001). CONCLUSION: Patient, surgical and recovery factors are associated with extended LOS in AIS patients who undergo posterior spinal fusion surgery. Extended LOS significantly increases healthcare spending. LEVEL OF EVIDENCE: Level III.

Synthetic Cages Associated With Increased Rates of Revision Surgery and Higher Costs Compared to Allograft in ACDF in the Nonelderly Patient.

OBJECTIVE: The aim of this study was to compare all-cause reoperation rates and costs in nonelderly patients treated with anterior cervical discectomy and fusion (ACDF) with structural allograft versus synthetic cages for degenerative pathology. METHODS: We queried a private claims database to identify adult patients ( ≤ 65 years) who underwent single-level ACDF in a hospital setting using either structural allograft or a synthetic cage (polyetheretherketone, metal, or hybrid device), from 2010 to 2016. The rate of all-cause reoperations at 2 years were compared between the 2 groups. Index hospitalization costs and 90-day complication rates were also compared. Significance was set at p < 0.05. RESULTS: A total of 26,754 patients were included in the study. 11,514 patients (43%) underwent ACDF with structural allograft and 15,240 (57%) underwent ACDF with a synthetic cage. The patients in the allograft group were younger and more likely to be male. There was no significant difference between the 2 groups with respect to 90-day complications including: wound dehiscence, dysphagia, dysphonia, and hematoma/seroma. In the 2-year postoperative period, the synthetic cage group had a significantly higher rate of allcause reoperation compared to the allograft group (9.1% vs. 8.0%, p = 0.002). Index hospitalization costs were significantly higher in the synthetic cage group compared to those in the allograft group ($23,475 vs. $20,836, p < 0.001). CONCLUSION: Structural allograft is associated with lower all-cause reoperation rates and lower index costs in nonelderly patients undergoing ACDF surgery for degenerative pathology. It is important to understand this data as we transition toward value-based care.

Emergency Department Visits After Posterior Spinal Fusion for Adolescent Idiopathic Scoliosis.

BACKGROUND: The incidence of emergency department (ED) visits after posterior spinal fusion (PSF) in adolescent idiopathic scoliosis (AIS) patients is not well known. We hypothesize that the majority of ED visits are related to constipation and pain issues, and are not for serious complications. METHODS: Using a private insurance claims database, we identified AIS patients aged 10 to 21 years who underwent PSF from 2010 to 2015. Patients were excluded for diagnoses of neuromuscular or syndromic scoliosis. ED visits that occurred within the 6-month postoperative period were identified. The diagnoses present at these visits were pooled and analyzed, in addition to insurance payments associated with these visits. Significance was set at P=0.05. RESULTS: A total of 5934 patients met inclusion criteria. Mean age was 14.4±2.2 years, and 75% of the patients were girls. A total of 577 (9.7%) patients had at least 1 ED visit in the 6-month postoperative period, whereas 92 (1.6%) had 2 ED visits and 19 (0.3%) had 3 or more ED visits. The median time to ED visits was 33 days after surgery. Independent risk factors for ED visits were: older age, and greater levels fused (P<0.05). The top 5 most common reasons for ED visits were: pain/back or musculoskeletal, constipation/GI issues, asthma/ respiratory issues, upper respiratory infection, and dehydration. Rates of ED visits were similar among the US geographic regions. Patients who had an ED visit had significantly higher total 6-month health care payments than those who did not (P<0.001). CONCLUSIONS: Approximately 10% of the patients had ≥1 ED visit in the 6-month period after PSF for AIS. A majority of the diagnoses at these ED visits were outpatient medical issues. LEVEL OF EVIDENCE: Level III.

Percutaneous abscess drainage: use of related radiology services and associated economic impact on a radiology practice.

PURPOSE: To evaluate the impact of percutaneous abscess drainage on the usage and professional value of subsequent services provided by a radiology practice. MATERIALS AND METHODS: Percutaneous abscess drainage was selected as a marker interventional radiology procedure because of its pervasiveness and ease of identification of related services. Billing records were reviewed for 48 consecutive patients who underwent abscess drainage during a 9-month period. Current procedural terminology (CPT) codes for all radiology services during the subsequent 90 days were analyzed to identify those related to the initial drainage procedure. Professional relative value unit (RVU) impact was calculated. RESULTS: Initial abscess drainage services were identified by 2.6 +/- 1.2 CPT codes, but patients underwent 13.4 +/- 10.7 related radiology services during the subsequent 90 days. The professional RVU impact of subsequent services was 64% higher than that of initial procedures: initial drainage services accounted for 11.5 +/- 5.1 RVUs and all subsequent related radiology services accounted for 18.9 +/- 16.8 RVUs (P =.0042). Of those, additional interventional radiology procedures amounted to 10.7 +/- 12.8 RVUs, diagnostic radiology services 4.7 +/- 4.6 RVUs, and evaluation and management services 3.5 +/- 2.9 RVUs. CONCLUSION: Basic interventional radiology services may result in far more economic impact on radiology practices than initial direct procedure analyses suggest. For percutaneous abscess drainage, the professional RVU impact of subsequent services exceeds that of the initial procedure by 64%. Practices negotiating capitated contracts for interventional services need to consider the high value of such related services.
