Trends of hand injuries presenting to US emergency departments: A 10-year national analysis
2021
The purpose was to observe current incidence and trends of hand and wrist injuries presenting to U.S. emergency departments (EDs) over a decade.
The National Electronic Injury Surveillance System (NEISS) was queried for hand and wrist injuries from January 2009–December 2018. Descriptive analyses were used to report injury types to the hand and wrist. Incidence, age, gender, race, injury location, and type of injury were recorded. Linear regression analyses were used to assess changes in trends over time. A p value <0.05 was statistically significant.
In total, 649,131 cases of hand and wrist injuries were identified in the NEISS from 2009 to 2018, correlating to 25,666,596 patients nationally. Incidence rates for finger, hand, and wrist were 450, 264, and 182 per 100,000 people. The estimated number of patients per year declined by 8.6% from 2009 to 2018. Male adults (aged 18–39) were the most frequent demographic. Total national estimates of hand (−8.2%; p = 0.001), wrist (−6.1%; p = 0.007), and finger (−9.9%; p < 0.001) injuries declined over the study period. The most common injuries were lacerations (36.5%), fractures (19.9%), strains/sprains (12.3%), and contusions/abrasions (12.1%) which significantly declined over the study period. The overall admission rate was 1.8%.
The estimated annual number of hand/wrist injuries presenting to US EDs was 2.6 million with gradual decline over the decade. Hand injury registries could assist in quality improvement measures targeted toward increased efficiency and resource allocation and education.

Elective surgery
2022
Introduction
As a result of the SARS-CoV-2 (COVID-19) pandemic in 2020, elective surgeries, including total joint arthroplasty (TJA), were suspended nationwide. Concurrent removal of total hip arthroplasty (THA) from the Medicare inpatient-only list posed challenges to the delivery of quality patient care with low payor cost. Therefore, the objective of this study was to compare temporal trends in patient demographics, case volumes, length of stay, and complications following elective THA in the years 2019 to 2020 in the United States.
Methods
The 2019 to 2020 ACS-NSQIP database was queried for elective THA patients. Patients Pre-COVID (2019 and 2020Q1) were compared with post-COVID (2020Q2-Q4). THA utilization, demographics, 30-day complications, and length of stay (LOS) were compared between years. Linear regression evaluated changes in case volumes over time with significance threshold of
P
< 0.05.
Results
A total of 77,797 patients underwent elective THA in 2019 (
n
= 43,667) and 2020 (
n
= 34,130), resulting in a 24.5% decline. Outpatient THA increased in 2020 (35.6%)
vs
. 2019 (5.7%) (
P
< 0.001). There was no significant difference in the volume of cases in 2019Q1 through 2019Q4 (
P
= 0.984). Elective THA volumes declined by 68.8% in 2020Q2, returned to pre-pandemic baseline in 2020Q3, before leveling off at 81.5% of baseline in Q4. Average LOS was significantly shorter in 2020 (1.55 days)
vs
. 2019 (1.78 days) (
P
< 0.001) and the proportion of same day discharge (SDD) increased quarterly from 2019 to 2020. There was no significant difference in the total complication rates in 2019 (6.6%)
vs
. 2020 (6.6%) (
P
= 0.831).
Discussion
Elective THA precipitously declined during the second quarter of 2020. The combined effect of policy changes and the COVID-19 pandemic resulted in a seven-fold increase in the number of surgeries performed in the outpatient setting in 2020. Rates of SDD doubled over the study period, despite no change in complication rates.

Clostridium difficile colitis following geriatric hip fracture surgery: incidence, trends, and risk factors from 45,910 patients
2023
PurposeClostridium difficile colitis is a serious complication in elderly patients undergoing surgery. The objectives of this study were: (1) to use a nationwide sample of patients to report the incidence and timing of C. difficile colitis in geriatric patients who underwent surgery for hip fractures, (2) to identify preoperative factors associated with developing C. difficile colitis and mortality. MethodsThis was a retrospective evaluation of the 2016–2019 ACS Targeted Hip Fracture database merged with the ACS-NSQIP database. Patients undergoing surgery for hip fracture were included. Outcomes studied were incidence, preoperative, and postoperative risk factors for occurrence of C. difficile infection and mortality. Chi-squared tests were used to compare demographics between the patients infected (study) and not infected (control). Logistic regression models were utilized to compute the odds ratios (OR) testing for the association of independent factors on developing C. difficile infection postoperatively and mortality. A statistical threshold was set at p < 0.008.ResultsThe incidence of C. difficile infection within 30 days of hip fracture surgery was 0.81%. Fifty percent of infections were diagnosed within 9 days postoperatively. Preoperative and hospital-associated factors associated with development of C. difficile infection were ≥ 2 days until operation (OR 1.88 [95% CI 1.39–2.55], p < 0.001) and dependent functional status (OR 1.43 [95% CI 1.14–1.79], p = 0.002). After adjusting for multiple comorbidities, increased age, male sex, COPD, CHF, dependent functional status, and C. difficile infection were associated with increased mortality within 30 days of surgery (all p < 0.001).ConclusionClostridium difficile colitis is a serious infection after hip fracture surgery in geriatric patients with an incidence of about 1%. Patients at increased risk should be targeted with preventative measures to prevent the morbidity from this complication.

Introduction:
The Centers for Medicare and Medicaid Services removed total hip arthroplasty (THA) from the inpatient-only (IO) list in January 2020. Given this recommendation, we analyzed Medicare-eligible patients undergoing outpatient THA to understand risk factors for nonroutine discharge, reoperations, and readmissions.
Materials and Methods:
The 2015-2018 American College of Surgeons–National Surgical Quality Improvement Program database was queried using Current Procedural Terminology code 27130 for Medicare eligible patients (≥ 65 years of age) undergoing outpatient THA. Postoperative discharge destination was categorized into home and non-home. Multivariate logistic regression models were used to evaluate risk factors associated with non-home discharge disposition. Secondarily, we evaluated rates and risk factors associated with 30-day reoperations and readmissions.
Results:
A total of 1095 THAs were retrieved for final analysis. A total of 108 patients (9.9%) experienced a non-home discharge postoperatively. Patients were discharged to rehab (n = 47; 4.3%), a skilled care facility (n = 47; 4.3%), a facility that was “home” (n = 8; 0.7%), a separate acute care facility (n = 5; 0.5%), or an unskilled facility (n = 1; 0.1%). Independent factors for a non-home discharge were American Society of Anesthesiologists Class >II (odds ratio [OR] 2.74), operative time >80 minutes (OR 2.42), age >70 years (OR 2.20), and female gender (OR 1.67). Eighteen patients (1.6%) required an unplanned reoperation within 30 days. A total of 40 patients (3.7%) required 30-day readmissions, with 35 readmissions related to the original THA procedure. Independent risk factors for 30-day reoperation were COPD (OR 5.85) and HTN (OR 5.24). Independent risk factors for 30-day readmission were HTN (OR 4.35) and Age >70 (OR 2.48).
Discussion:
The current study identifies significant predictors associated with a non-home discharge, reoperation, and readmission in Medicare-aged patients undergoing outpatient THA.
Conclusion:
Providers should consider preoperatively risk-stratifying patients to reduce the costs associated with unplanned discharge destination, complication or reoperation.

Iron Deficiency Anemia
2022
Background
Recent studies show an increase in the prevalence of iron deficiency anemia (IDA) worldwide and a concomitant rise in the number of revision total knee arthroplasty (RTKA). The literature evaluating the association between IDA and perioperative outcomes following RTKA are limited. Therefore, the purpose of this study was to determine whether IDA patients undergoing RTKA have higher rates of (1) in-hospital lengths of stay (LOS), (2) complications; and (3) costs.
Methods
Using International Classification of Disease, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT), a retrospective query was performed from January 1
st
, 2005 to March 31
st
, 2014. The inclusion criteria consisted of those patients who have IDA undergoing RTKA. Study group patients were 1:5 ratio matched to a comparison cohort by age, sex, and various comorbidities: coronary artery disease, chronic obstructive pulmonary disease, diabetes mellitus, hyperlipidemia, hypertension, obesity, and tobacco use, yielding a total of 106,534 patients within the study (
n
= 17,784) and control (
n
= 88,750) cohorts. Outcomes assessed included: in-hospital LOS, costs of care, and medical complications. Multivariate Logistic regression analyses were used to calculate the odds-ratios (OR) and respective 95% confidence intervals (95%CI). Welch’s
t-
tests were used to compare in-hospital LOS and costs of care. Following Bonferroni-correction, a
P-
value less than 0.001 was considered statistically significant.
Results
IDA patients undergoing RTKA were found to have significantly higher in-hospital LOS (4-days
vs
. 3-days,
P
< 0.0001). Additionally, IDA patients were found to have significantly higher odds (OR) of medical complications (OR: 5.29,
P
< 0.0001) such as: pneumonia (OR: 6.86,
P
< 0.0001), respiratory failures (OR: 5.95,
P
< 0.0001), myocardial infarctions (OR: 4.31,
P
< 0.0001) and other complications. Furthermore, IDA patients incurred significantly higher day of surgery ($16,976.01
vs
. $14,515.81,
P
< 0.0001) and 90-day costs ($22,548.71
vs
. $16,819.15,
P
< 0.0001).
Conclusion
The study demonstrated IDA patients undergoing RTKA have higher rates of in-hospital LOS, costs of care, and medical complications. Orthopedic surgeons and other healthcare professionals can use this information to adequately educate these patients of the potential complications following their procedure.

Pediatric Patients with Osteomyelitis and/or Septic Joint Undergoing Surgical Debridement Have Equivalent Short-Term Outcomes with or without Preoperative MRI
2024
The purpose of this study was to determine if short-term outcomes differed for pediatric patients with suspected musculoskeletal infection with or without a preoperative MRI. This was a multicenter, retrospective review of patients aged 0–16 years who presented with atraumatic extremity pain, underwent irrigation and debridement (I&D), and received at least one preoperative or postoperative MRI over a 10-year period. Primary outcomes were time to OR, total I&Ds, readmission rate, time from OR to discharge, and total number of MRIs. Secondary outcomes entailed the rate at which concurrent osteomyelitis was identified in patients with septic arthritis and the extent of the resulting surgical debridement. Of the 104 patients, 72.1% had a preoperative MRI. Patients with a preoperative MRI were significantly less likely to have surgery on the day of admission. No difference was found between groups regarding total I&Ds, readmission rate, time from OR to discharge, and total number of MRIs. Of the 57 patients diagnosed with septic arthritis, those with a preoperative MRI were significantly more likely to have concurrent osteomyelitis identified and to undergo bony debridement in addition to arthrotomy of the joint. In conclusion, patient outcomes are not adversely affected by obtaining a preoperative MRI despite the delay in time to OR. Although preoperative MRI can be beneficial in ruling out other pathologies and identifying the extent of concurrent osteomyelitis, the decision to obtain a preoperative MRI and timing of surgery should be left to the discretion of the treating surgeon.

Which surgeon demographic factors influence postoperative complication rates after total knee arthroplasty at U.S. News and World Report top-ranked orthopedic hospitals?
2022
Introduction
Complication rates are used to evaluate surgical quality-of-care and determine health care reimbursements. The
U.S. News & World Report
(USNWR) hospital rankings are a highly-referenced source for top hospitals. The objective of this study was to determine the surgeon demographics of those practicing at USNWR Top Ranked Orthopedic Hospitals and if any influence complication rates after total knee arthroplasty (TKA).
Methods
The 2009–2013 USNWR ‘Orthopedic’ hospital rankings were identified. A database of TKA surgeons with postoperative complication rates was compiled utilizing publicly available data from the Centers for Medicare and Medicaid Services (2009–2013). Using an internet search algorithm, demographic data were collected for each surgeon and consisted of: fellowship training, years in practice, age, gender, practice setting, medical degree type, residency reputation, case volume, and geographic region of hospital. Logistic regression was used to assess the relationship between surgeon demographics and postoperative complication rates. A
P
value of < 0.008 was considered significant.
Results
From 2009 to 2013, 660 orthopedic surgeons performed TKA at 80 different USNWR Top-Ranked Hospitals. Mean TKA case volume was 172 (Range, 20–1323) and age of surgeon was 50.8 (Range, 32–77). A total of 372 (56.8%) completed an orthopedic surgery fellowship. Mean adjusted 30-day complication rate was 2.24% (Range, 1.2–4.5%). After adjustment, factors associated with increased complication rates were surgeon age ≤ 42 (OR 3.15;
P
= 0.007) and lower case volume (≤ 100 cases) (OR 2.52;
P
< 0.0001). Gender, hospital geographic region, completion of a fellowship, medical degree type, and residency reputation were not significant factors.
Discussion
Complication rates of total knee arthroplasty surgeons may be utilized by patients and hospitals to gauge quality of care. Certain surgeon factors may influence complication rates of surgeons performing TKA at USNWR Top Ranked Orthopedic Hospitals.

The Utility of the Standardized Letter of Recommendation for Orthopedic Surgery Residency Applicants: A Systematic Review
2024
Despite widespread adoption for evaluating residency candidates, few studies have evaluated the orthopedic standardized letter of recommendation (SLOR). A systematic review using PubMed, Embase, and Web of Science was performed in June 2022. Study design and results from SLOR investigations were compiled. Common outcomes studied were summative rank statement scores and SLOR individual domains. Applicants were rated ranked to match or in the top one-third of rank lists in non-normally distributed frequencies. The association of summative rank statement score with match outcome was rarely studied. Applicants' ratings skew positively, the utility is reportedly limited, and influence on match outcome has been inadequately studied. [Orthopedics. 2024;47(1):e1–e5.]

Firework Injuries to the Hand in the United States: An Epidemiological and Cost Analysis
2023
Although prior literature has evaluated firework injuries broadly, there are no focused investigations examining trends, etiology, and costs associated with firework injuries to the hand. The 2006 to 2014 National Emergency Department Sample (NEDS) was used. International Classification of Diseases, Ninth Revision (ICD-9) codes identified patients presenting to the emergency department with a firework-related injury of the hand that resulted in a burn, open wound, fracture, blood vessel injury, or traumatic amputation. A linear regression model was used to identify significant changes over time, with a significance threshold of P<.05. A total of 19,473 patients with a firework-related injury to the hand were included, with no significant change in the incidence from 2006 to 2014 (7.5 per 1,000,000 population). The greatest number of injuries occurred in July (57.1%), January (7.4%), and December (3.7%). Age groups affected were young adults (18–35 years; 43.6%), older adults (36–55 years; 19.2%), adolescents (12–17 years; 18.6%), and children (0–11 years; 16.1%). Nearly 74% of the injuries resulted in burns, 24.5% resulted in open wounds, 8.0% resulted in fracture, 7.6% resulted in traumatic amputation, and 1.4% resulted in blood vessel injury. Of 14,320 burn injuries, 15.2% had first-degree burns, 69.9% had second-degree burns, and 5.1% had third-degree burns involving the skin. The median emergency department charge was $914 and the median hospitalization charge (for inpatient admittance) was $30,743. Incidence of firework-related injuries to the hand has not changed over time. There is a need for better dissemination of safety information to mitigate the occurrences of these avoidable accidents.

Social determinants of health in patients undergoing hemiarthroplasty: are they associated with medical complications, healthcare utilization, and payments for care?
2023
IntroductionSocial determinants of health (SDOH) have previously been shown to impact orthopedic surgery outcomes. This study assessed whether greater socioeconomic disadvantage in patients undergoing hemiarthroplasty following femoral neck fracture was associated with differences in (1) medical complications, (2) emergency department (ED) utilization, (3) readmission rates, and (4) payments for care.MethodsA US nationwide database was queried for hemiarthroplasties performed between 2010 and 2020. Area Deprivation Index (ADI), a validated measure of socioeconomic disadvantage reported on a scale of 0–100, was used to compare two cohorts of greater and lesser deprivation. Patients undergoing hemiarthroplasty from high ADI (95% +) were 1:1 propensity score matched to a comparison group of lower ADI (0–94%) while controlling for age, sex, and Elixhauser Comorbidity Index. This yielded 75,650 patients evenly distributed between the two cohorts. Outcomes studied were 90-day medical complications, ED utilizations, readmissions, and payments for care. Multivariate logistic regression models were utilized to calculate odds ratios (ORs) of the relationship between ADI and outcomes. p Values < 0.05 were significant.ResultsPatients of high ADI developed greater medical complications (46.74% vs. 44.97%; OR 1.05, p = 0.002), including surgical site infections (1.19% vs. 1.00%; OR 1.20, p = 0.011), cerebrovascular accidents (1.64% vs. 1.41%; OR 1.16, p = 0.012), and respiratory failures (2.27% vs. 2.02%; OR 1.13, p = 0.017) compared to patients from lower ADIs. Although comparable rates of ED visits (2.92% vs. 2.86%; OR 1.02, p = 0.579), patients from higher ADI were readmitted at diminished rates (10.57% vs. 11.06%; OR 0.95, p = 0.027). Payments were significantly higher on the day of surgery ($7,570 vs. $5,974, p < 0.0001), as well as within 90 days after surgery ($12,700 vs. $10,462, p < 0.0001).ConclusionsSocioeconomically disadvantaged patients experience increased 90-day medical complications and payments, similar ED utilizations, and decreased readmissions. These findings can be used to inform healthcare providers to minimize disparities in care.Level of evidenceIII.
