RESUMO
PURPOSE: The purpose of this study was to compare the complication rates of endoscopic carpal tunnel release (ECTR) relative to orthopedic resident trainee involvement in the procedure. METHODS: All patients undergoing isolated, elective ECTR by two attending surgeons within a 59-month period were analyzed. Cases were categorized as the following according to the degree of resident involvement: ECTR performed by attending with either no resident or a resident as an assistant (group 1), resident performing a portion of the procedure (group 2), and resident performing the entire procedure (group 3). Early postoperative complications and/or intraoperative conversion to an open procedure were the outcomes of interest. We used a noninferiority design, hypothesizing that resident involvement would not be associated with inferior outcomes compared with cases without resident involvement. Multiple logistic regression models, adjusted for patient demographic and surgical characteristics, were fit to assess the relationship between resident involvement groups and complication/conversion outcomes. RESULTS: A total of 1,167 ECTR cases (895 patients) were performed and returned for postoperative follow-up for at least 2 weeks after surgery. Operative time was significantly shorter for group 1 cases versus group 2 and 3 cases. The early postoperative complication and conversion rates were 1.7% and 1.0%, respectively. Superficial infection (1.2%), deep infection (0.3%), and transient neuropraxia (0.3%) occurred infrequently and did not differ relative to resident involvement. No differences in the odds of complication and/or conversion relative to resident involvement were observed. CONCLUSIONS: The results of ECTR performed entirely or in part by attending-supervised resident trainees were not inferior to ECTR performed by an attending surgeon regarding the odds of experiencing complications or conversion to an open procedure. With appropriate supervision, ECTR can be performed safely by orthopedic and plastic surgery residents. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

PURPOSE: The CTS-6 can be used clinically to diagnose carpal tunnel syndrome (CTS) and has demonstrated high levels of interrater reliability when administered by nonexpert clinicians. Our purpose was to assess sensitivity (Sn), specificity (Sp), and interrater reliability of the CTS-6 when administered by medical assistants (MAs). METHODS: A series of patients presenting to an academic, upper-extremity surgery clinic were screened using CTS-6 between May and June of 2023. The CTS-6 was first administered by one of seven MAs and then by one of four fellowship-trained upper-extremity surgeons. In addition to recording baseline demographics, the results of each of the six history and examination components of the CTS-6 were recorded, as was the cumulative CTS-6 score (0-26). Surgeons were blinded to the scores obtained by the MAs. Interrater reliability (Cohen's kappa) was determined between the groups with respect to the diagnosis of CTS and the individual CTS-6 items. Sensitivity/specificity was calculated for the MA-administered CTS-6, using the score obtained by the surgeon as the reference standard. A CTS-6 score >12 was considered diagnostic of CTS. RESULTS: Two hundred eighteen patients were included, and 26% had a diagnosis of CTS. The MA group demonstrated a Sn/Sp of 84%/91% for the diagnosis of CTS. Interrater reliability was substantial (Cohen's kappa: 0.72, 95% confidence interval: 0.62-0.83) for MAs compared with hand surgeons for the diagnosis of CTS. For individual CTS-6 components, agreement was lowest for the assessment of two-point discrimination (fair) and highest for the assessment of subjective numbness (near perfect). CONCLUSIONS: The CTS-6 demonstrates substantial reliability and high Sn/Sp when administrated by MAs in an upper-extremity clinic. These data may be used to inform the development of CTS screening programs and future investigations in the primary care setting. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

PURPOSE: Our purpose was to compare differences in the incidence of amyloid deposition in tenosynovium (TS) versus transverse carpal ligament (TCL) biopsies obtained during open carpal tunnel release. We hypothesized that the incidence of amyloid would be similar between TCL and TS when obtaining both specimens from the same patient. METHODS: All primary, elective open carpal tunnel release cases that underwent biopsy for amyloid between January 2022 and September 2023 were reviewed. Tenosynovial and TCL specimens were independently evaluated by a pathologist to assess for amyloid. Demographic data were collected, and incidence of amyloid deposition was compared between the two samples. Agreement statistics, sensitivity, and specificity were calculated for TCL, using TS as the reference standard. RESULTS: A total of 196 cases met either Tier 1 (n=180) or Tier 2 (n=16) biopsy criteria. Forty-eight cases were excluded for missed biopsies or laboratory processing errors, leaving 148 cases available for analysis. Amyloid deposition was present in 31 out of 148 (21%) TS specimens and 33 out of 148 (22%) TCL specimens. Overall, the results of the TS biopsy agreed with TCL biopsy in 138 out of 148 cases (93%). In the 10 cases for which the results of the TCL and TS biopsy differed, six cases had (+) TCL and (-) TS, and four cases had amyloid deposition in TS without evidence of deposition in the TCL. Sensitivity and specificity values for the TCL specimen were 87% and 95%, respectively. Positive and negative predictive values were 82% and 97%, respectively. CONCLUSIONS: For cases of open carpal tunnel release undergoing biopsy, amyloid deposition was noted in 21% of TS specimens and 22% of TCL specimens. Results of TS and TCL biopsies obtained from the same patient agreed in 93% of cases. Single-source biopsy for amyloid represents a reasonable diagnostic approach. Future cost analyses should be performed to determine whether the addition of two biopsy sources to improve diagnostic accuracy is justified. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.
RESUMO
PURPOSE: Subacromial decompression (SAD) has historically been described as an essential part of the surgical treatment of rotator cuff disorders. However, investigations throughout the 21st century have increasingly questioned the need for routine SAD during rotator cuff repair (RCR). Our purpose was to assess for changes in the incidence of SAD performed during RCR over a 12-year period. In addition, we aimed to characterize surgeon and practice factors associated with SAD use. METHODS: Records from two large tertiary referral systems in the United States from 2010 to 2021 were reviewed. All cases of RCR with and without SAD were identified. The outcome of interest was the proportion of SAD performed during RCR across years and by surgeon. Surgeon-specific characteristics included institution, fellowship training, surgical volume, academic practice, and years in practice. Yearly trends were assessed using binomial logistic regression modeling, with a random effect accounting for surgeon-specific variability. RESULTS: During the study period, 37,165 RCR surgeries were performed by 104 surgeons. Of these cases, 71% underwent SAD during RCR. SAD use decreased by 11%. The multivariable model found that surgeons in academic practice, those with lower surgical volume, and those with increasing years in practice were significantly associated with increased odds of performing SAD. Surgeons with fellowship training were significantly more likely to use SAD over time, with the greatest odds of SAD noted for sports medicine surgeons (odds ratio = 3.04). CONCLUSIONS: Although SAD use during RCR appears to be decreasing, multiple surgeon and practice factors (years in practice, fellowship training, volume, and academic practice) are associated with a change in SAD use. CLINICAL RELEVANCE: These data suggest that early-career surgeons entering practice are likely driving the trend of declining SAD. Despite evidence suggesting limited clinical benefits, SAD remains commonly performed; future studies should endeavor to determine factors associated with practice changes among surgeons.

PURPOSE: Previous investigations assessing the incidence of amyloidosis detected with biopsy during carpal tunnel release (CTR) have focused on open CTR (OCTR). Prior authors have suggested that biopsy may be more technically challenging during endoscopic carpal tunnel release (ECTR). Our purpose was to compare differences in the incidence of amyloid deposition detected during ECTR versus OCTR. METHODS: We reviewed all primary ECTR and OCTR during which a biopsy for amyloid was obtained between February 2022 and June 2023. All procedures were performed by five upper-extremity surgeons from a single institution. Congo red staining was used to determine the presence of amyloid deposition in either the transverse carpal ligament (TCL) or tenosynovium. All positive cases underwent subtype analysis and protein identification through liquid chromatography-tandem mass spectrometry. Baseline demographics were recorded for each case, and the incidence of positive biopsy was compared between ECTR and OCTR cases. RESULTS: A total of 282 cases were included for analysis (143 ECTR and 139 OCTR). The mean age was 67 years, and 45% of cases were women. Baseline demographics were similar except for a significantly higher incidence of diabetes in OCTR cases (13% vs 33%). Overall, 13% of CTR cases had a positive biopsy. There was a statistically significant difference in the incidence of amyloid deposition detected during biopsy in ECTR cases (3.5%) compared with OCTR cases (23%). CONCLUSIONS: Biopsy performed during ECTR may result in a lower incidence of amyloid detection. Future basic science investigation may be necessary to determine histologic differences between tenosynovium proximal and distal to the leading edge of the TCL. When surgeons plan a biopsy during surgical release of the carpal tunnel, an open approach may be advantageous. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

PURPOSE: Patients considering total elbow arthroplasty (TEA) may be receiving immunosuppressive therapy; however, the relationship between immunosuppressive medications and postoperative complications is not well defined. Our purpose was to assess the relationship between preoperative immunosuppression and short-term complications following TEA. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was reviewed from 2005 to 2020 to identify patients undergoing TEA. Procedures indicated for malignancy or infection were excluded. Patients were grouped according to preoperative chronic immunosuppressive status. Demographic and operative characteristics were compared between groups. The 30-day incidence of complications and reoperations were compared between groups. Multiple logistic regression models, inverse-weighted by propensity scores, were used to calculate odds ratio (OR) of experiencing any complication or return to the operating room based on immunosuppression status and other demographic characteristics. RESULTS: A total of 769 patients undergoing TEA were included, of whom 142 (18.5%) received chronic immunosuppression. Distribution of age, sex, race, body mass index, diabetes, and American Society of Anesthesiologists classification differed significantly between groups. Most procedures were performed on an inpatient basis, and the median operative duration was 148 minutes. Most procedures were indicated for fracture in the nonimmunosuppressed group and rheumatoid arthritis in the immunosuppressed group. Overall complication rates were 7.0% for immunosuppressed patients and 10.2% for nonimmunosuppressed patients. The incidence of complications and reoperations did not significantly differ between groups. After controlling for confounding and adjusting for patient characteristics, immunosuppressed patients were 0.52 times less likely to experience a complication. Additionally, there was no association between immunosuppression status and odds of return to the operating room. CONCLUSION: Similar rates of complications were observed following TEA, regardless of preoperative immunosuppression status. Chronic immunosuppression does not appear to increase the rates of postoperative complications for patients undergoing TEA. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Purpose: The purpose of our study was to compare unplanned postoperative patient communication in the form of phone calls and/or electronic patient portal messages (EPPM) after carpal tunnel release (CTR) for patients with and without a postoperative opioid prescription. Methods: We identified all patients ≥18 years of age who underwent primary CTR between 2017 and 2022 without an opioid ordered within 90 days prior to surgery. The following two groups were created: cases with and without an opioid prescribed on the day of surgery. We recorded baseline demographics for all patients and recorded all unplanned communication (phone calls and EPPM) sent from a patient to the surgeon's office within 14 days after surgery. Unadjusted associations between unplanned communication and case characteristics were evaluated. Multiple logistic regression models were used to assess the relationship between opioid status and unplanned communication. Results: A total of 5,735 CTRs were included, and 54% of the patients were prescribed an opioid on the day of surgery. Forty-two percent of cases had unplanned postoperative communication, and 48.1% of cases, without an opioid prescription, had unplanned communication compared with 36.8% in the opioid group. Patients who were prescribed opioids were 0.62 times less likely to contact the surgeon's office via phone calls or EPPM (95% confidence interval [CI]: 0.56, 0.70). Increased age was associated with a reduction in the odds of unplanned contact (odds ratios [OR] = 0.95, 95% CI: 0.93, 0.97), whereas higher body mass index was significantly associated with increased communication (OR = 1.05, 95% CI: 1.01, 1.09). Conclusions: Patients prescribed opioids after CTR are 0.62 times less likely to contact the surgeon's office after surgery. Considering the 11% increase in unplanned postoperative communication after CTR, surgeons should consider alternative methods that have previously been demonstrated to reduce opioid consumption. Type of study/level of evidence: Prognostic II.
RESUMO
Purpose: Statistical literacy is the ability of a patient to apply basic statistical concepts to their health care. Understanding statistics is a critical component of shared decision making. The purpose of this investigation was to define levels of statistical literacy in an upper-extremity (UE) patient population. We aimed to determine if patient demographics would be associated with statistical literacy. Methods: An electronic survey was administered to a consecutive series of UE patients at a single institution. We recorded baseline demographics, Single Assessment Numeric Evaluation scores, the Berlin Numeracy Test (BNT), and General Health Numeracy Test. We also included a surgical risk question, which asked: "Approximately 3% of patients who get carpal tunnel surgery develop an infection. If 100 patients get this surgery, how many would you expect to develop an infection?" A covariate-controlled adjusted odds ratio reflecting the association between each statistical literacy outcome measure and patient characteristics was reported. Results: A total 254 surveys were administered, 148 of which were completed and included. Fifty percent of respondents had a high-school education or less. For the BNT, 78% scored in the bottom quartile, and 52% incorrectly answered all questions. For the General Health Numeracy Test, 34% answered 0 or 1/6 questions correctly. For the surgical risk question, 24% of respondents answered incorrectly. Respondents who had a college or graduate degree had 2.62 times greater odds (95% confidence interval, 1.09-6.32) of achieving a BNT score in a higher quartile than patients who did not have a college or graduate degree. Conclusions: Overall levels of statistical literacy are low for UE patients. Clinical relevance: When engaging in management discussions and shared decision making, UE surgeons should assume low levels of statistical literacy. Consideration of alternative formats, such as frequencies, video-based materials, and pictographs, may be warranted when discussing outcomes and risks of surgical procedures.
RESUMO
BACKGROUND: Lung transplant (LTx) recipients have low long-term survival and a high incidence of bronchiolitis obliterans syndrome (BOS). However, few long-term, multicenter, and precise estimates of BOS-free survival (a composite outcome of death or BOS) incidence exist. METHODS: This retrospective cohort study of primary LTx recipients (1994-2011) reported to the International Society of Heart and Lung Transplantation Thoracic Transplant Registry assessed outcomes through 2012. For the composite primary outcome of BOS-free survival, we used Kaplan-Meier survival and Cox proportional hazards regression, censoring for loss to follow-up, end of study, and re-LTx. Although standard Thoracic Transplant Registry analyses censor at the last consecutive annual complete BOS status report, our analyses allowed for partially missing BOS data. RESULTS: Due to BOS reporting standards, 99.1% of the cohort received LTx in North America. During 79,896 person-years of follow-up, single LTx (6,599 of 15,268 [43%]) and bilateral LTx (8,699 of 15,268 [57%]) recipients had a median BOS-free survival of 3.16 years (95% confidence interval [CI], 2.99-3.30 years) and 3.58 years (95% CI, 3.53-3.72 years), respectively. Almost 90% of the single and bilateral LTx recipients developed the composite outcome within 10 years of transplantation. Standard Registry analyses "overestimated" median BOS-free survival by 0.42 years and "underestimated" the median survival after BOS by about a half-year for both single and bilateral LTx (p < 0.05). CONCLUSIONS: Most LTx recipients die or develop BOS within 4 years, and very few remain alive and free from BOS at 10 years post-LTx. Less inclusive Thoracic Transplant Registry analytic methods tend to overestimate BOS-free survival. The Registry would benefit from improved international reporting of BOS and other chronic lung allograft dysfunction (CLAD) events.

BACKGROUND: The proportion of deceased donor kidneys recovered for transplant but discarded increased steadily in the United States over 2 decades, from 5.1% in 1988 to 19.2% by 2009. Over 100 000 patients are waiting for a kidney transplant, yet 3159 kidneys were discarded in 2015. METHODS: We evaluated trends in donor characteristics, discard reasons, and Organ Procurement Organization-specific discard rates. Multivariable regression and propensity analysis were used to estimate the proportion of the discard rate rise in the 2000s attributable to changes in donor factors and decisions to biopsy and pump kidneys. RESULTS: This study found that at least 80% of the discard rate rise can be explained by the recovery of kidneys from an expanding donor pool and changes in biopsy and pumping practices. However, a residual discard rate increase could not be explained by changes in these factors. From 1987 to 2009, median donor age rose from 26 to 43 years; median Kidney Donor Risk Index increased from 1.1 in 1994 to 1.3 in 2009. Our findings suggest that the increase from 10% to 30% in the proportion of kidneys pumped during the 2000s served as a buffer, keeping the discard rate from rising even higher than it did. CONCLUSIONS: The majority of the kidney discard rate rise can be explained by the broadening donor pool. However, the presence of an unexplained, residual increase suggests behavioral factors (eg, increased risk aversion) and/or allocation inefficiencies may have played a role. Reducing risk aversion, improving allocation, and more often pumping less-than-ideal, yet potentially transplantable kidneys, may help reverse the trend.
