The wide variety of patient-reported outcome measures used to assess outcomes following total joint arthroplasty can present a substantial methodological obstacle when attempting to compare ...information across studies or between institutions. A simple solution is to create crosswalks that reliably convert scores between patient-reported outcome measures. Our goal is to create and validate crosswalks between the commonly used Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) and short-form versions of the Hip Disability and Osteoarthritis Outcome Score Joint Replacement (HOOS JR)/Knee Injury and Osteoarthritis Outcome Score (KOOS JR.).
Patients in our joint replacement registry were included if they underwent primary total hip arthroplasty (n = 4649) or total knee arthroplasty (n = 3750) for osteoarthritis between May 2007 and February 2012. We used their preoperative and 2-year postoperative HOOS scores (n = 6351) or KOOS scores (n = 4688) to generate the patients’ WOMAC and HOOS JR/KOOS JR scores. The equipercentile equating method was applied to create 10 crosswalks: HOOS JR/KOOS JR to WOMAC Total (WOMAC-T), and WOMAC-T, WOMAC Pain (WOMAC-P), WOMAC Stiffness (WOMAC-S), and WOMAC Function (WOMAC-F) to HOOS JR/KOOS JR. Crosswalk validity was assessed by comparing actual and derived scores using Spearman’s rank correlation coefficients in a bootstrapped cohort.
All 10 crosswalks showed strong positive correlations ranging from 0.846 (WOMAC-S to KOOS JR) to 0.981 (HOOS JR to WOMAC-T).
We created and validated 10 crosswalks between WOMAC and HOOS JR/KOOS JR. We recommend using the crosswalks between WOMAC-T and HOOS JR/KOOS JR when possible, as they demonstrated the highest correlation. WOMAC-F or WOMAC-P should be used in favor of WOMAC-S if only subscores are available. The HOOS JR/KOOS JR should only be converted to a WOMAC-T.

There are approximately 300,000 people in the United States who are co-infected with HIV and HCV. Several organizations recommend that individuals who are HCV infected, as well as persons over the ...age of 13, should be HIV tested. Comorbidities associated with HCV can be reduced with early identification of HIV. Our objective was to determine whether providers routinely followed HIV testing guidelines for patients who tested HCV positive (HCV+).
A retrospective chart review was conducted of all patients in primary care at an academic health system from 7/2015-3/2017 who tested HCV+. As part of a primary database, HCV testing data was collected; HIV testing data was abstracted manually. We collected and described the intervals between HCV and HIV tests. To determine associations with HIV testing univariable and multivariable analyses were performed.
We identified 445 patients who tested HCV+: 56.6% were tested for HIV, the mean age was 57 ± 10.9 years, 77% were from the Birth Cohort born 1945-1965 (BC); 61% were male; and 51% were Black/AA. Patients in the BC were more likely to be HIV tested if they were: male (p = 0.019), Black/AA (p<0.001), and had Medicaid (p = 0.005). These differences were not found in the non-BC. Six patients who were tested for both HIV and HCV were found to be newly HIV positive at the time of testing.
As demonstrated, providers did not routinely follow CDC recommendations as almost half of the HCV+ patients were not correctly tested for HIV. It is important to emphasize that six persons were tested HIV positive simultaneously with their HCV+ diagnosis. If providers did not follow the CDC guidelines, then these patients may not have been identified. Improvements in EHR clinical decision support tools and provider education can help improve the HIV testing rate among individuals who are HCV+.

Prior research has shown that industry funding can impact the outcomes reported in medical literature. Limited data exist on the degree of bias that industry funding may have on shoulder arthroplasty ...literature outside of the Journal of Shoulder and Elbow Surgery. The purpose of this study is to characterize the type and frequency of funding for recently published shoulder arthroplasty studies and the impact of industry funding on reported outcomes. We hypothesized that studies with industry funding are more likely to report positive outcomes than those without.
We performed a retrospective study searching all articles with the term “shoulder arthroplasty,” “reverse shoulder arthroplasty,” “anatomic total shoulder arthroplasty,” or “total shoulder arthroplasty” on PubMed from the years January 2020 to December 2022. The primary outcome of studies was coded as either positive, negative, or neutral. A positive result was defined as one in which the null hypothesis was rejected. A negative result was defined as one in which the result did not favor the group in which the industry-funded implant was used. A neutral result was defined as one in which the null hypothesis was confirmed. Article funding type, subcategorized as National Institutes of Health funding or industry funding was recorded. Author disclosures were recorded to determine conflicts of interest. Statistical analysis was conducted using the χ2 test and Fisher exact test.
A total of 750 articles reported on either conflict of interest or funding source and were included in the study. Of the total number of industry-funded studies, the majority were found to have a positive primary endpoint (58.1%, 104 of 179), as compared to a negative (7.8%, 14 of 179) or neutral endpoint (33.5%, 60 of 179) (P = .004). Overall, 363 articles reported an author conflict of interest, and the majority of these studies had positive primary endpoint (55.6%, 202 of 363) as compared to negative (9.1%, 33 of 363) or neutral endpoints (34.4%, 125 of 363) (P = .002).
The results of this study suggest that there is a significant relationship between conflicts of interest and the primary outcome of shoulder arthroplasty studies, beyond the overall positive publication bias. Studies with industry funding and author conflicts of interest both report positive outcomes more frequently than negative outcomes. Shoulder surgeons should be aware of this potential bias when choosing to base clinical practice on published data.
CDC reported that 45% of Hepatitis C (HCV) infected people denied known risk factors. Electronic health record RF-based, non-Birth Cohort (born outside of years 1945-1965) screening is challenging as ...risk factors are often input as nonsearchable data. Testing non-Birth Cohort patients solely based on risk factors has the potential to miss a substantial number of HCV infected patients. The aim was to determine the HCV antibody positive prevalence who would have been missed had providers only followed risk factor based screening recommendations.
A 1:3 case-control retrospective nested chart review was conducted. HCV risk factors and opioid prescriptions were manually abstracted from the Electronic Health Record; other variables were collected using Explorys. In July 2015 HCV screening data was collected on non-Birth Cohort patients who were HCV tested across MedStar Health, as a presumptive marker for high risk. Univariate and multivariate logistic regression models were utilized to determine HCV antibody positive predictors.
Eighteen (23%) HCV antibody positive and 123 (49%) HCV antibody negative had no identified risk factors; 6 (33%) HCV antibody positive reported risk factors only after a positive test result. There was a significant interaction between age over 40 and opioid prescription use; these groups were 11× more likely to be HCV antibody positive (CI95 1.6-74.8).
HCV testing solely based on presence of risk factors in non-Birth Cohort patients has the potential to miss a significant number of HCV antibody positive patients. Given patient- and provider-level barriers in elucidating risk factors, universal HCV antibody screening may be warranted.
Background:
The population of nonagenarians undergoing total joint arthroplasty (TJA) of the hip or knee is expected to increase, but this population may be reluctant to consider elective surgery ...because of their advanced age.
Purpose:
We sought to compare TJA outcomes between nonagenarians and octogenarians with an exact 10-year age difference.
Methods:
We performed a retrospective chart review, including 129 nonagenarians who underwent primary unilateral TJA for osteoarthritis in a 4-year period at a single institution and who were matched with 381 octogenarians based on sex, body mass index, Charlson Comorbidity Index, replaced joint (hip or knee), and a 10-year age difference. Ninety-day outcomes included Centers for Medicare and Medicaid Services (CMS) defined complications, unscheduled outpatient clinic visits, emergency room (ER) visits, and readmissions. No patients were lost to follow-up.
Results:
Nonagenarians and octogenarians had comparable rates of CMS complications (10% vs 6.3%, respectively), but nonagenarians had higher rates of CMS mechanical complications (6.2% vs 1.6%). There was 1 death in each group. Nonagenarians had longer hospital stays than octogenarians (4.1 vs 3.0 days, respectively), and a greater risk of in-hospital events and complications (60.5% vs 37.3%, respectively). The groups showed similar rates of unscheduled outpatient visits (14.7% vs 13.9%, respectively), ER visits (12.4 vs 6.6%, respectively), and readmissions (6.2% vs 7.1%, respectively).
Conclusions:
This retrospective study found higher rates of in-hospital complications in nonagenarians than in matched octogenarians following elective TJA, although the 2 groups showed similar rates of postdischarge complications. Further research in a larger cohort is needed.
A cesarean scar pregnancy is an iatrogenic consequence of a previous cesarean delivery. The gestational sac implants into a niche created by the incision of the previous cesarean delivery, and this ...carries a substantial risk for major maternal complications. The aim of this study was to report, analyze, and compare the effectiveness and safety of different treatments options for cesarean scar pregnancies managed in the first trimester through a registry.
This study aimed to evaluated the ultrasound findings, disease behavior, and management of first-trimester cesarean scar pregnancies.
We created an international registry of cesarean scar pregnancy cases to study the ultrasound findings, disease behavior, and management of cesarean scar pregnancies. The Cesarean Scar Pregnancy Registry collects anonymized ultrasound and clinical data of individual patients with a cesarean scar pregnancy on a secure, digital information platform. Cases were uploaded by 31 participating centers across 19 countries. In this study, we only included live and failing cesarean scar pregnancies (with or without a positive fetal heart beat) that received active treatment (medical or surgical) before 12+6 weeks’ gestation to evaluate the effectiveness and safety of the different management options. Patients managed expectantly were not included in this study and will be reported separately. Treatment was classified as successful if it led to a complete resolution of the pregnancy without the need for any additional medical interventions.
Between August 29, 2018, and February 28, 2023, we recorded 460 patients with cesarean scar pregnancies (281 live, 179 failing cesarean scar pregnancy) who fulfilled the inclusion criteria and were registered. A total of 270 of 460 (58.7%) patients were managed surgically, 123 of 460 (26.7%) patients underwent medical management, 46 of 460 (10%) patients underwent balloon management, and 21 of 460 (4.6%) patients received other, less frequently used treatment options. Suction evacuation was very effective with a success rate of 202 of 221 (91.5%; 95% confidence interval, 87.8–95.2), whereas systemic methotrexate was least effective with only 38 of 64 (59.4%; 95% confidence interval, 48.4–70.4) patients not requiring additional treatment. Overall, surgical treatment of cesarean scar pregnancies was successful in 236 of 258 (91.5%, 95% confidence interval, 88.4–94.5) patients and complications were observed in 24 of 258 patients (9.3%; 95% confidence interval, 6.6–11.9).
A cesarean scar pregnancy can be managed effectively in the first trimester of pregnancy in more than 90% of cases with either suction evacuation, balloon treatment, or surgical excision. The effectiveness of all treatment options decreases with advancing gestational age, and cesarean scar pregnancies should be treated as early as possible after confirmation of the diagnosis. Local medical treatment with potassium chloride or methotrexate is less efficient and has higher rates of complications than the other treatment options. Systemic methotrexate has a substantial risk of failing and a higher complication rate and should not be recommended as first-line treatment.
