Disease recurrence in patients undergoing mastectomy for ductal carcinoma in situ.

With DCIS incidence on the rise, up to 30% of patients undergo mastectomy for Ductal carcinoma in situ (DCIS) (Nash and Hwang, in: Ann Surg Oncol 30(6):3206-3214, 2023). Local recurrence rates after mastectomy for DCIS are reportedly low, but risk factors for recurrence are not known (Kim et al., in: J Cancer Res Ther 16(6):1197-1202, 2020). We aim to define risk factors associated with ipsilateral breast cancer recurrence in patients undergoing mastectomy for DCIS. We aimed to identify risk factors that may contribute to recurrence of breast cancer following mastectomy for pure DCIS. We hypothesized that close or positive mastectomy margins, age at diagnosis, extent of breast disease and mutation carriers would be associated with increased risk of recurrence. We performed a retrospective chart review of patients who underwent unilateral or bilateral mastectomies for pure DCIS at a single academic tertiary referral center from 2013 to 2023. There were 165 patients who met inclusion criteria with an average length of follow-up of 39.9months. On final surgical pathology, the average span of DCIS was 33.7mm (± 24.6mm). Hormone receptor positive disease was identified in 80.6% of the patient cohort. For margin status, 23 patients (14%) had < 1mm margins on final pathology and of those, 1 received adjuvant radiation therapy and 4 returned to the OR for re-excision. Only 1 (0.6%) patient had ipsilateral disease recurrence during the study period. Recurrence after mastectomy for pure DCIS is a rare event and in our study sample, only one recurrence occurred. Risk factors for recurrence appear unrelated to margin status, age, extent of DCIS, or pathogenic mutation (ElSherif et al., in Am J Surg 226(5):646-651, 2023).

Medical Decision-Making and Bereavement Experiences After Cardiac Arrest: Qualitative Insights From Surrogates.

Surrogates of incapacitated patients in the intensive care unit (ICU) face decisions related to life-sustaining treatments. Decisional conflict is understudied. To compare experiences of ICU surrogates by reported level of decisional conflict related to treatment decisions after a patient's cardiac arrest preceding death. Convergent mixed methods were used. Bereaved surrogates recruited from a single northeastern US academic medical center completed surveys including the low-literacy Decisional Conflict Scale (moderate-to-high cut point >25) and individual interviews about 1 month after the patient's death. Interview data were analyzed by directed and conventional content analysis. Surrogates were stratified by median total survey score, and interview findings were compared by decisional conflict level. Of 16 surrogates, 7 reported some decisional conflict (median survey score, 0; range, 0-25). About two-thirds decided to withdraw treatments. Three themes emerged from interviews: 2 reflecting decision-making experiences ("the ultimate act"; "the legacy of clinician communication") and 1 reflecting bereavement experiences ("I wish there was a handbook"). Surrogates reporting decisional conflict included those who first pursued but later withdrew treatments after a patient's in-hospital cardiac arrest. Surrogates with decisional conflict described suboptimal support, poor medical understanding, and lack of clarity about patients' treatment preferences. These findings provide insight into bereaved ICU surrogates' experiences. The low overall survey scores may reflect retrospective measurement. Surrogates who pursued treatment were underrepresented. Novel approaches to support bereaved surrogates are warranted.

Ten-Year Outcome After Supracricoid Partial Laryngectomy in cT3M0 Laryngeal Squamous Cell Carcinoma-A STROBE Analysis.

The aim of this study was to document 10-year outcomes after supracricoid partial laryngectomy (SCPL) in selected cT3M0 laryngeal squamous cell carcinoma (SCC) patients. This real-life retrospective observational study analyzed an inception cohort of 168 patients with isolated, untreated, selected cT3M0 laryngeal SCC, that were consecutively managed by SCPL during the period 1973-2013, and followed up until death or for a minimum of 10 years in 92% of cases at a single French academic and tertiary referral care center. Prior induction chemotherapy, arytenoid cartilage removal, level II-IV neck dissection, and postoperative radiation therapy were performed on 148, 77, 136, and 27 patients, respectively. The main objective was to determine 10-year actuarial local control and laryngeal preservation estimates. Secondary objectives included 10-year actuarial survival and cause-of-death analysis, and assessment of correlations between endpoints and clinical variables. The significance threshold was set at p < 0.005. Ten-year actuarial local control, laryngeal preservation, and survival estimates were 90%, 85%, and 52%, respectively. Salvage treatment resulted in an overall 99% local control rate. Metachronous second primary cancer, intercurrent disease without evidence of SCC, SCPL-related death, and uncontrolled local recurrence accounted for 31%, 26%, 7%, and 2% of causes of death. On univariate analysis, overall local recurrence and laryngeal preservation rates varied significantly, from 5% to 54% and 90% to 46% when resection margins were R0 and R1, respectively. The present study highlighted successful 10-year outcomes after SCPL, providing further evidence in favor of its integration into the conservative armamentarium for endolaryngeal cT3 SCC. 4 Laryngoscope, 134:4557-4563, 2024.

Report of cardiac electronic device implant complications over a 7-year study period

Abstract Background The global placement of cardiac implantable electronic devices (CIEDs) is on the rise. Complications linked to device implantation present a substantial burden on healthcare systems and patients alike. It is imperative to comprehend the complication rates associated with CIED procedures, enabling informed decision-making and strategic planning for patients, thereby enhancing the overall quality of care. Purpose We sought to determine post CIED implantation complication rates and provide operator specific complication data for quality assurance at our institution. Methods A comprehensive audit of all procedures completed between April 2016 to March 2023 by 14 high volume operators at a single academic center was completed. Complications and device data were extracted using electronic medical records. Complications evaluated include pneumothorax, infections, hematomas, venous thrombosis, lead perforation, and dislodgement using standardized definitions. Results During the 7-year period, a total of 9,467 procedures were completed. Among the cohort, 62% were male, with an average age of 74.6 ± 15.2 years. The procedural breakdown comprised 60% pacemakers, 19% ICDs, 16% CRTs and 3% ILRs. A total of 11,616 leads were implanted (3,644 RA leads and 1,110 LV leads). The overall complication rate was 3.1% (n=316): device pocket infection 0.68%, superficial infection 0.19%, lead dislodgement 0.53%, lead perforation 0.24%, pericardial effusion 0.1%, pneumothorax 0.15%, pocket hematoma 0.83%, DVT 0.36%, and hemothorax 0.02%. Complication rates per operator are shown in Figure-1. Conclusion Our findings indicate that the overall complication rates for CIED implants are lower than previously reported rates, and there is no significant difference between operators in overall rates of complication. This observation can be attributed to operator experience, advancements in peri-operative care and guideline-directed post-operative protocols. However, notable variations exist among operators in rates of pocket infection. The ongoing monitoring of CIED complications as a quality indicator remains a crucial benchmark, meriting annual assessments for ongoing evaluation.

Pupillary Peaking & Presence of Dysphotopsias Following Glaucoma Tube Shunt Surgery

ABSTRACT Purpose To describe the presence of pupillary peaking and dysphotopsias in a sample of eyes following glaucoma drainage device (GDD) surgery. Methods Cross-sectional analysis of 68 glaucoma patients with GDD, 45 patients with glaucoma and no GDD, and 50 control patients was conducted in a single academic center. Patients with an appropriate diagnosis that met the inclusion criteria were asked to enroll in the study. All patients received an 8-item dysphotopsia questionnaire and were age-matched. Photographs of pupils were taken to assess pupillary peaking. One-way analysis of variance (ANOVA) testing was performed for statistical analysis. Results Of the 68 patients with GDD, 25 (36.76%) had pupillary abnormalities with peaking most commonly occurring in the direction of the tube entry superotemporally, and 50 (73.53%) had reported one or more dysphotopsias. In patients reporting one or more dysphotopsias, the rate of lines, crescents, ghost images, and shadows was significantly higher when compared to glaucoma patients without GDD and control patients (p < .01). This corresponded to a lower best-corrected visual acuity in the GDD group compared to the glaucoma and control groups (p < .001). Conclusions Over a third of glaucoma patients receiving GDD had pupillary abnormalities, and nearly 3 out of 4 patients with GDD reported one or more dysphotopsias when compared to glaucoma patients without GDD and an age-matched control group. Glaucoma specialists and patients should be aware of these complications when proceeding with GDD surgery.

Outcomes for Female Physicians Compared With Nonphysicians After Assisted Reproductive Technology.

To evaluate outcomes of female physicians after assisted reproductive technology (ART). We conducted a retrospective cohort study using data from 248 physician patients and 3,470 nonphysician patients who underwent a total of 10,095 fresh or frozen ART cycles at a single academic center in an insurance-mandated state between January 2015 and March 2022. The primary outcome was live-birth rate. The secondary outcomes were implantation rate, early pregnancy loss rate, and time to pregnancy. Models were adjusted for confounders where appropriate. Both groups were similar in age (mean physician age 36.29 years; mean nonphysician age 35.96 years, P=.35). Physicians had lower body mass index (BMI) (mean physician BMI 23.51, mean nonphysician BMI 26.37, P<.01), and a higher proportion were diagnosed with unexplained infertility (physician 33.9%, nonphysician 25.9%, P<.01) and used preimplantation genetic testing for aneuploidy (physician 21.5%, nonphysician 12.7%). Physicians and nonphysicians had similar live-birth rates (physician 39.3%, nonphysician 38.2%; adjusted relative risk [aRR] 1.01 95% CI, 0.91-1.13), implantation rates (physician 34.7%, nonphysician 33.7%; relative risk 1.03 95% CI, 0.94-1.14), and early pregnancy loss rates (physician 21.9%, nonphysician 19.8%; aRR 1.18 95% CI, 0.99-1.41) per transfer. Physicians had a shorter time from initial ART cycle to pregnancy (physician 21.82 weeks, nonphysician 25.16 weeks; aRR 0.86, 95% CI, 0.83-0.89). There was no difference between female physicians and nonphysicians in assisted reproduction cycle outcomes. Physicians become pregnant slightly faster than nonphysicians.

A retrospective review of revision and re-revision patella osteosynthesis performed for failure of fixation of initial comminuted fracture patterns: very high complication rates.

Literature on revision osteosynthesis for failed patella fracture fixation is extremely limited. This study reviews the treatment options and outcomes for revision and re-revision osteosynthesis at a Level 1 Trauma Center. All patella revision osteosynthesis between January 2021 and March 2024 were identified using Current Procedural Terminology (CPT) codes at a single tertiary care academic centre. Medical records, operative reports and radiographs were reviewed to collect details regarding patient demographics, initial injury and fracture management, indications for revision surgery, revision construct, post-operative weight bearing and range of motion restrictions, and outcomes. The primary outcome was major failure defined as loss of fixation or further surgery for non-union or infection. Ten patients underwent revision osteosynthesis for failed fixation. All fractures were initially comminuted fracture patterns (AO/OTA 34-C3), with nine (90%) initially treated with a 2.7mm patella-specific variable angle (VA) locking plate (Synthes, Paoli, PA). Half (n=5) of the patients were revised with the same patella specific plate and half with an all suture transosseous fibertape tension band (Arthrex, Naples, FL). Additional fixation in the form of bony augmentation was performed in 20% (n=2) of cases and soft tissue augmentation in 70% (n=7). There was a 70% (n=7) major failure rate, mostly due to loss of inferior pole fixation. There were four re-revision procedures performed with surgical fixation. Two of these subsequently developed infection, one united and the other had no radiographic signs of union and was lost to follow-up, but was without complication. Regardless of the chosen fixation construct, revision osteosynthesis for failed fixation of initial comminuted fracture patterns has an extremely high rate of failure. Complications increase with further revision surgery.

Emergent cesarean section during active labor-does cervical dilatation matter?

To compare the immediate and late complications associated with emergent cesarean sections (CS) performed during the first and second stages of active labor. We conducted a retrospective analysis of electronic medical records from a single academic center, including data from 577 patients who underwent emergent cesarean sections at 4cm or more of cervical dilatation. Patients were divided into two groups: those who had CS during the first stage of labor (4-9cm dilatation) and those who had CS at complete dilatation (10cm). Maternal and neonatal outcomes were compared, including rates of complications such as uterine atony, post-partum hemorrhage, infection, and neonatal intensive care unit (NICU) admission. Of the 577 patients, 352 underwent CS during active labor and 255 at complete dilatation. The complete dilatation group exhibited significantly higher rates of uterine atony (19.6% vs. 11.6%, p = 0.009) and uterine incision extension (34.2% vs. 16.5%, p = 0.0001). In addition, they had longer hospital stays (4.8 vs. 4.25days, p = 0.003) and higher outpatient clinic visit rates (21.3% vs. 9.9%, p = 0.0001). Infection-related complications on readmission were more common in the complete dilatation group (20% vs. 9.7%, p = 0.001). Neonatal outcomes, including APGAR scores and NICU admissions, did not differ significantly between the groups. Emergent cesarean sections performed at complete cervical dilatation are associated with increased intra-operative and post-operative complications compared to those performed during active labor. These findings highlight the importance of considering the stage of labor when planning cesarean delivery to minimize risks and optimize outcomes for both mother and neonate.

Intraarticular hip corticosteroid injections offer no meaningful benefit in delaying time to total hip arthroplasty in patients with hip osteoarthritis

IntroductionSymptomatic hip osteoarthritis (OA) causes significant morbidity and functional limitations. While corticosteroid injections (CSI) are commonly offered and administered for OA pain relief, it is unknown if they offer any clinically meaningful long-term benefit or reduce the overall need for surgical intervention.MethodsA cross-sectional retrospective cohort study was performed on primary hip osteoarthritis patients from a single academic tertiary-care center arthroplasty clinic from 2014 to 2019. Patients were divided into three groups. CSI + THA: hip CSI patients who underwent subsequent ipsilateral THA. CSI-noTHA: hip CSI who have not had ipsilateral THA to date. THA-noCSI: a control group of consecutive hip OA patients who underwent primary THA without prior CSI. Demographic variables, injection relief duration, and radiographic arthritis severity were recorded. Time from clinic presentation to injection and/or THA were compared.Results357 patients met inclusion criteria and underwent guided, arthroplasty provider-ordered CSI. Mean duration of relief was 6.7 weeks (SD 8.7). 244 injection patients (67.2%) subsequently underwent THA (CSI + THA). 150 of 390 patients have not undergone THA at mean of 25.5 months follow-up. Mean time from clinic presentation to THA was 8.6 months longer after CSI (16.3, SD 17.8) months in CSI patients compared to 7.7 (SD 10.6) months for patients without CSI (p < 0.001). Of 117 patients in the CSI-noTHA group at mean 25 months follow-up, only 43 (12% of all injection patients) had not had THA because they found injections effective. The remaining 74 (63%) of CSI-noTHA patients have been deemed medically unfit for surgery or are currently scheduled for THA.Discussion/ConclusionThe results of this study suggest the utilization of intra-articular CSI as conservative treatment in an arthroplasty clinic does not prolong time to THA for a clinically important duration. The use of CSI should be reserved for diagnostic purposes and/or short-term pain relief in poor surgical candidates.Level of evidenceIII.

External evaluation of a commercial artificial intelligence-augmented digital auscultation platform in valvular heart disease detection using echocardiography as reference standard

ObjectiveThere are few studies evaluating the accuracy of commercially available AI-powered digital auscultation platforms in detecting valvular heart disease (VHD). Therefore, the utility of these systems for diagnosing clinically significant VHD remains unclear. We conducted a comprehensive external evaluation of the Eko murmur analysis software (EMAS) and report its accuracy in detecting murmurs associated with VHD using echocardiography (ECHO) as the reference standard. MethodsWe analyzed phonocardiogram (PCG) and ECHO data from 1,029 individuals (461 females, mean (SD) age: 61 (29) years, BMI: 29 (9)) at a single academic medical center. PCGs were recorded using the EkoDUO and EkoCORE stethoscopes from the four standard auscultation positions immediately before transthoracic ECHO (TTE) testing. TTE diagnostics were used as reference to calculate the EMAS sensitivity and specificity in detecting murmurs associated with VHD. The 95% confidence intervals are reported. ResultsOf the 4,081 PCGs, 79% were of sufficient quality for murmur analysis. The sensitivity and specificity of the EMAS in detecting VHD were 39.3% (95% CI: 37.2–41.3) and 82.3% (95% CI: 80.0–84.5), respectively. EMAS sensitivity in detecting murmurs associated with common VHD types was 62.5%, 75.0%, 88.9%, and 63.3% for moderate-severe and severe cases of mitral stenosis, aortic regurgitation, aortic stenosis, and mitral regurgitation, respectively. ConclusionThe EMAS algorithm exhibits limited overall sensitivity in detecting VHD. The sensitivity of the algorithm varies across VHD types. These findings suggest that EMAS can be used for diagnosis of specific lesions, but not all VHD types, which limits its clinical applicability as a screening tool.

Electronic Health Record User Dashboard for Optimization of Surgical Resident Procedural Reporting.

Background While necessary and educationally beneficial, administrative tasks such as case and patient tracking may carry additional burden for surgical trainees. Automated systems targeting these tasks are scarce, leading to manual and inefficient workflows. Methods We created an electronic health record (EHR)-based, user-specific dashboard for surgical residents to compile resident-specific data: bedside procedures performed, operative cases performed or participated in, and notes written by the resident as a surrogate for patients cared for. Usability testing was performed with resident volunteers, and residents were also surveyed post-implementation to assess for efficacy and satisfaction. Access log data from the EHR was used to assess dashboard usage over time. Descriptive statistics were calculated. Results The dashboard was implemented on a population of approximately 175 surgical residents in 5 different departments (General Surgery, Obstetrics and Gynecology, Neurosurgery, Orthopedics, and Otolaryngology) at a single academic medical center. 6 resident volunteers participating in usability testing completed an average of 96% of preset tasks independently. Average responses to five questions extracted from the System Usability Scale (SUS) questions ranged from 4.0 to 4.67 out of 5. Post-implementation surveys indicated high resident satisfaction (4.39 out of 5) and moderate rates of use, with 46.4% of residents using the dashboard at least monthly. Daily use of the dashboard has increased over time, especially after making the dashboard a default for surgical residents. Conclusion An EHR-based dashboard compiling resident-specific data can improve the efficiency of administrative tasks and supplement longitudinal education.

Facial trauma education in radiology: using surgeon feedback as the benchmark for success.

Interpreting CT studies of facial trauma is challenging, and there are often substantial differences in the characterization of complex facial trauma between radiologists and surgeons. We designed a collaborative multidisciplinary project to reconcile differences in facial fracture interpretation through an educational intervention. The effectiveness of this intervention was evaluated through surgeon feedback on radiology reports. Radiology residents, neuroradiology fellows, and neuroradiology attendings were recruited as participants at a single tertiary care academic center. Otolaryngology residents were recruited as evaluators. Participants completed surveys and provided preliminary reports for example cases of facial trauma before and after attending an educational session. Evaluators performed a blinded review of these preliminary reports based on ideal reports developed by surgical and neuroradiology attendings. 26 participants (20 residents, 1 neuroradiology fellow, 5 neuroradiology attendings) completed the study. Six otolaryngology residents participated as evaluators. To assess interrater reliability, three evaluators graded a shared set of 15 reports and demonstrated substantial agreement with a Kendall's W of 0.71. Participants demonstrated significant improvement in overall report accuracy, clarity, and organization. In subunit analysis, there were significant improvements in reporting Le Fort, nasoseptal, and nasoorbitoethmoid fractures. No significant improvements occurred in the reporting of upper face, zygomaticomaxillary complex, or mandibular fractures. In contrast, survey analysis demonstrated significantly improved confidence in interpreting trauma involving all facial subunits. Compared with survey results, surgeon assessment of radiology reports better demonstrated areas of improvement after an educational intervention. A multidisciplinary approach to assessing educational efforts may better evaluate the practical effectiveness of educational interventions.

Preservation of the MMPH and Status of the Notch Configurations Are Important Factors for Successful Revision ACL Reconstruction.

The aim of this study was to identify the differences in anatomical factors between the patients who underwent revision and primary anterior cruciate ligament reconstructions (ACLR) and compare the outcomes between the 2 surgeries. Retrospective cohort study. Single institution tertiary academic center between 2014 and 2020. A total of 84 matched patients who underwent revision (group I) or primary ACLR (group II). Radiological evaluations were performed using side-to-side differences (SS-D), femorotibial angle, and posterior tibial slope. The medial meniscus posterior horn status as width (MMPHW), medial tibial plateau width (MTPW), notch configurations, tunnel positions, and sagittal graft angle were measured using 3D-CT and magnetic resonance imaging (MRI). Graft signals were assessed using MRI. The clinical outcomes were assessed. Group I showed larger SS-D and higher mean Howell grade of anterior cruciate ligament (ACL) graft than group II (P = 0.002 and P = 0.004, respectively). Multivariate regression analyses showed that the decreased MMPHW/MTPW ratio (P = 0.010) and notch width index (P < 0.007) were significantly independent factors associated with the higher Howell grade of ACL grafts. The decreased MMPHW/MTPW ratio (P < 0.001) was a significantly independent factor associated with larger SS-D. In the subgroup analysis, all patients in the notchplasty group showed wider notches postoperatively (P < 0.001). Revision ACLRs resulted in worse ACL signal intensity and stability outcome. The results of this study suggest that it may be important to preserve the MMPHW as much as possible and check notch configurations, especially during a revision ACLR.

A RETROSPECTIVE REVIEW OF LONG-TERM PATIENT-REPORTED OUTCOME MEASURES COMPARING UNSTABLE ANKLE FRACTURES WITH AND WITHOUT A POSTERIOR MALLEOLUS FRACTURE

The aim of this study was to evaluate the long-term outcomes of patients who had sustained an unstable ankle fracture with a posterior malleolus fracture (PMF) and without (N-PMF).Adult patients presenting to a single academic trauma centre in Edinburgh, UK, between 2009 and 2012 with an unstable ankle fracture requiring surgery were identified. The primary outcome measure was the Olerud Molander Ankle Score (OMAS). Secondary measures included Euroqol-5D-3L Index (Eq5D3L), Euroqol-5D-VAS and Manchester Oxford Foot Questionnaire (MOXFQ).There were 304 patients in the study cohort. The mean age was 49.6 years (16.3–78.3) and 33% (n=100) male and 67% (n=204) female. Of these, 67% (n=204) had a PMF and 33% did not (n=100). No patient received a computed tomography (CT) scan pre-operatively. Only 10% of PMFs (22/204) were managed with internal fixation. At a mean of 13.8 years (11.3 – 15.3) the median OMAS score was 85 (Interquartile Range 60 – 100). There was no difference in OMAS between the N-PMF and PMF groups (85 [56.25 – 100] vs 85 [61.25 – 100]; p = 0.580). There was also no difference for MOXFQ (N-PMF 7 [0 – 36.75] vs PMF 8 [0–38.75]; p = 0.643), the EQ5D Index (N-PMF 0.8 [0.7 – 1] vs PMF 0.8 [0.7 – 1]; p = 0.720) and EQ5D VAS (N-PMF 80 [70 – 90] vs PMF 80 [60 – 90]; p = 0.224).The presence of a PMF does not affect the long-term patient reported outcomes in patients with a surgically managed unstable ankle fracture.

Telemedicine and Access to Elective Cholecystectomy for Socially Vulnerable Adults

Socially vulnerable patients with symptomatic cholelithiasis are more likely to face barriers to accessing surgical care. This barrier to access can lead to delays in treatment, the need for emergent cholecystectomy, and worse outcomes. To determine the effectiveness of telemedicine vs in-person surgical consultation on access to elective cholecystectomy in socially vulnerable populations and to evaluate the association of scheduling navigation with access to elective cholecystectomy in these populations. This pilot randomized clinical trial conducted in a single academic center enrolled 60 adults from February 1, 2023, to February 21, 2024, with 3-month follow-up of clinical outcomes. Data were also collected retrospectively on a comparison group of 32 patients referred from June 30 to December 29, 2022. Adults with social vulnerability, such as being non-White or Hispanic or having nonprivate insurance or low income, with a diagnosis of symptomatic cholelithiasis and referral for outpatient surgical consultation were included. All trial participants were randomized to the telemedicine or in-person surgical consultation group, and received professional scheduling navigation. The latter intervention was compared with a historical cohort without navigation assistance. The primary outcome was completion of outpatient surgical consultation. Secondary outcomes included receipt of treatment and operative urgency. The trial enrolled 60 participants (30 per arm). Their mean (SD) age was 48.2 (18.2) years, 50 (83.3%) were female, 2 (3.3%) were Asian, 39 (65.0%) were Black, 8 (13.3%) were Hispanic, 11 (18.3%) were White, and 41 (68.3%) had no private insurance. The historical patient cohort included 32 participants (mean [SD] age, 45.9 [3.2] years; 27 [84.4%] female; 3 [9.4%] Asian, 15 [46.9%] Black, 10 [31.3%] Hispanic, and 6 [18.8%] White; and 18 [56.3%] without private insurance). In total, 18 trial participants assigned to telemedicine (60.0%) completed surgical consultations compared with 23 trial participants assigned to in-person visits (76.7%; P = .17). For telemedicine participants who underwent cholecystectomy, 3 of 7 (42.9%) underwent emergent cholecystectomy compared with 0 of 14 (0%) participants with in-person consultations (P = .03). Of 30 trial participants who received scheduling navigation, 23 (76.7%) completed surgical consultations compared with 15 of 32 patients in the historical cohort who did not receive scheduling navigation (46.9%; P = .02). Of 14 trial participants who received scheduling navigation and cholecystectomy, no participants underwent emergent cholecystectomy compared with 4 of 16 (25.0%) participants in the historical cohort without scheduling navigation (P = .04). In this pilot randomized clinical trial of socially vulnerable adults with symptomatic cholelithiasis, telemedicine consultation compared with in-person visits did not improve access to elective outpatient surgical care. However, scheduling navigation services may improve access to elective outpatient surgical care. Future large-scale studies are needed to identify possible barriers to virtual health care and mechanisms to address inequities. ClincialTrials.gov Identifier: NCT05745077.

Management of vancomycin-resistant Enterococci and daptomycin-resistant Enterococci infections in liver transplant recipients in a single academic center.

Vancomycin-resistant Enterococci (VRE) infections cause significant morbidity and mortality in liver transplant (LT) recipients. Management is challenging, especially in the setting of daptomycin resistance (DR). Single-center retrospective review of patients who underwent LT between January 1, 2020, and December 31, 2022, and developed VRE infections. Descriptive statistics were used and Kaplan-Meier curves estimated freedom from treatment failure and survival. Forty-two patients (median age 58; 64% female; 67% white) were included. Alcohol-related cirrhosis (48%) and metabolic dysfunction-associated steatohepatitis (31%) were the most common indications for LT, and most were from deceased donors (86%). VRE infection occurred at a median of 21 days after LT, and 16% had known prior VRE colonization. Common infection sites were blood (45%, n = 19), intraabdominal (36%, n = 15), and urine (36%, n = 15). Most were initially treated with daptomycin alone (64%) or in combination with other agents (21%); 7% received linezolid alone. Twelve (29%) developed breakthrough infections during treatment and 11 (26%) had recurrent infections after discontinuation of treatment. All-cause mortality was 36% (n = 15) at a median of 90 days after VRE infection diagnosis and was nearly twice as high in patients with DR (63%). VRE infection in LT recipients relapsed or recurred in over 25%. Mortality was high, especially in cases with DR. More data is needed to establish an optimal treatment approach, particularly for relapse and DR.

The impact of routine cholangiography for asymptomatic patients after cholecystostomy insertion for acute cholecystitis

BackgroundWe aim to investigate the impact of routine cholangiography on asymptomatic patients with percutaneous cholecystostomy (PCC) for acute cholecystitis (AC). MethodsThe study included all patients treated with PCC for AC from 2017 to 2020 ​at a single academic center. Patients who underwent routine cholangiography within 30 days post-discharge while asymptomatic were compared to patients who were only followed clinically. ResultsThe groups (cholangiography group, n ​= ​44, and control group, n ​= ​145) were similar in terms of age, comorbidities, and clinical presentation. The readmission rate for biliary disease in the cholangiography group was nearly half that of the control group (22.7 ​% vs. 40.7 ​%, p ​= ​0.05) over an average follow-up of 10.4 months. The time to drain removal, cholecystectomy rate, and time to operation were comparable between the groups (42 vs. 40 days, p ​= ​0.47, 52.3 ​% vs 53.1 ​%, p ​= ​NS and 69 vs. 82 days, p ​= ​0.17, respectively). ConclusionsRoutine cholangiography can help reduce biliary disease readmissions among asymptomatic patients with PCC for AC without delaying further treatment.

Mandible Fracture Outcome Disparities in the Incarcerated Patient Population.

Inmates represent a vulnerable health care population within the United States, with inconsistent access to surgical specialty care. Facial fractures are common among the incarcerated population, comprising approximately 14% of all traumatic injuries. However, few studies have evaluated facial fracture outcomes in this population. The aim of this study is to identify disparities in mandible fracture outcomes in the incarcerated population. A retrospective review of all isolated traumatic mandible fractures at a single academic medical center from 2018 to 2023 was conducted. Mandible fractures were treated by plastic surgery, otolaryngology, or oral and maxillofacial surgery. Outcome measures such as rates of persistent malocclusion, motor deficits, surgical site infection, reoperation, and readmission were compared between inmate and civilian subgroups. A total of 205 patients (mean age, 33.1 years; 81.5% male) who were treated for isolated traumatic mandible fracture were included. A minority of patients (11.7%; n = 24) were inmates, whereas 88.3% (n = 181) were civilians. The mean time to operative intervention was 10.2 days in the incarcerated group and 4.4 days in the civilian group (P < 0.05). Persistent subjective malocclusion after surgery was noted in 20.8% (n = 5) of incarcerated patients and 7.2% (n = 13) of civilian patients (P < 0.05). There were no significant differences in rates of surgical site infection, reoperation, persistent motor deficits, or readmissions within 30 days. Incarcerated patients with traumatic mandible fractures have increased time to operative intervention and increased rates of subjective malocclusion postoperatively. Increased time to operative intervention may reflect barriers in access to specialty surgical care, which could adversely affect patient outcomes.

Patient-Centered Cost Saving and Positive Environmental Impact With the Introduction of Telehealth Services at a Single Center.

To establish the patient-specific cost and time savings associated with telemedicine with the secondary environmental benefits of virtual visits within a tertiary referral center sub-specialty urology clinic. An electronic health record query was made of all urology telehealth visits that have occurred between October 4, 2020 and October 10, 2020 at a single academic center. We evaluated the cost of travel for an in-person visit based on zip code data. To adjust for productivity loss, the cost of missed work was added as either full day or half day-based distance and average compensation per day based on zip code data. Environmental impact was calculated using average CO2 emissions per mile not traveled. There were 6444 patients seen in the urology clinic via telehealth during the 6-month period. Urology patients traveled on average 69 ± 148 miles round-trip for an appointment. The average cost savings per patient including the cost of the gas and time away from work was $152.78 ± $105.90. Overall, over a 6-month period, the total cost savings was $984,534.73 for the 6444 patients seen via telemedicine. There was also a significant environmental impact of the decreased travel burden with 153.36 metric tons of CO2 emissions eliminated. With the implementation of telehealth during the COVID-19 pandemic, patients have been able to save a substantial amount of time and money primarily driven by the decreasing work hours lost and cost of travel.
