Center-level outcomes following elective fenestrated endovascular aortic aneurysm repair in the Vascular Quality Initiative database.

OBJECTIVE: Hospital volume is associated with mortality after open aortic aneurysm repair. Fenestrated and branched endovascular aortic repair (B-FEVAR) has been increasingly used for repair of complex thoracoabdominal and juxtarenal aneurysms, but evidence of a center-volume relationship is limited. We aimed to measure the association of center volume with in-hospital mortality, postoperative outcomes, and 1-year survival following B-FEVAR. METHODS: Patients undergoing elective endovascular thoracoabdominal and complex abdominal aneurysm repair with branch intervention (2014-2021) listed within the national Vascular Quality Initiative Thoracic Endovascular Aortic Repair/Complex EVAR database were analyzed. Centers were grouped into quartiles by mean annual procedure volume. Multivariable regression was used to evaluate the effect of center volume on in-hospital mortality adjusting for baseline and procedural characteristics. Kaplan-Meier estimation, log rank test, and mixed effects Cox regression were used to evaluate 1-year survival. RESULTS: A total of 4302 adult elective F-BEVAR procedures were identified at a total of 163 centers. In-hospital mortality did not differ by hospital volume (quartile [Q]1 = 35/1059 [3.3%]; Q2 = 30/1063 [2.8%]; Q3 = 33/1120 [2.9%]; and Q4 = 44/1060 [4.2%]; P = .308). The high volume group had a higher rate of major complication (Q1 = 14.9%; Q2 = 12.8%; Q3 = 13.3%; and Q4 = 20.1%; adjusted P < .001). Physician-modified grafts were more frequently employed in high-volume centers (Q1 = 4.5%; Q2 = 18.7%; Q3 = 11.3%; and Q4 = 19.2%; P < .001), with a decreased incidence of any endoleak noted at the end of the procedure (Q1 = 34.9%; Q2 = 32.8%; Q3 = 30.0%; and Q4 = 29.0%; P = .003). In the multivariable analysis, in-hospital mortality was not associated with center volume, comparing very low volume to medium- and high-volume centers (odds ratio [95% confidence interval] vs Q4: Q1 = 1.1 [0.6-1.9], Q2 = 0.6 [0.4-1.1], and Q3 = 0.9 [0.5-1.5]; all P > .05). No significant difference was found in 1-year survival between center volume groups. CONCLUSIONS: In-hospital mortality is not associated with procedure volume within centers performing complex endovascular aortic repair. However, complication rates and endoleak may be associated with procedure volume. Long-term outcomes by annualized procedure volume, specifically graft durability and sac expansion, should be investigated.

Temporal Cluster Analysis of Deep Sternal Wound Infection in a Regional Quality Collaborative.

INTRODUCTION: Deep sternal wound infection (DSWI) is a rare complication associated with high mortality. Seasonal variability in surgical site infections has been demonstrated, however, these patterns have not been applied to DSWI. The purpose of this study was to assess temporal clustering of DSWIs. METHODS: All cardiac surgery patients who underwent sternotomy were queried from a regional Society of Thoracic Surgeons database from 17 centers from 2001 to 2019. All patients with the diagnosis of DSWI were then identified. Cluster analysis was performed at varying time intervals (monthly, quarterly, and yearly) at the hospital and regional level. DSWI rates were calculated by year and month, and compared using mixed-effects negative binomial regression. RESULTS: A total of 134,959 patients underwent a sternotomy for cardiac surgery, of whom 469 (0.35%) developed a DSWI. Rates of DSWI per hospital across all years ranged from 0.12% to 0.69%. Collaborative-level rates of DSWIs were the greatest in September (0.44%) and the lowest in January (0.30%). Temporal clustering was not seen across seasonal quarters (high rate in preceeding quarter was not associated with a high rate in the next quarter) (P = 0.39). There were yearly differences across all institutions in the DSWI rates. A downward trend in DSWI rates was seen from 2001 to 2019 (P < 0.001). A difference among hospitals in the cohort was observed (P < 0.001). CONCLUSIONS: DSWI are a rare event within our region. Unlike other surgical site infection, there does not appear to be a seasonal pattern associated with DSWI.

Operating Room Versus Intensive Care Unit Extubation Within 6 Hours After On-Pump Cardiac Surgery: Early Results and Hospital Costs.

Time-directed extubation (fast-track) protocols may decrease length of stay and cost but data on operating room (OR) extubation is limited. The objective of this study was to compare the outcomes of extubation in the OR versus fast-track extubation within 6 hours of leaving the operating room. Patients undergoing nonemergent STS index cases (2011-2021) who were extubated within 6 hours were identified from a regional STS quality collaborative. Patients were stratified by extubation in the OR versus fast track. Propensity score matching (1:n) was performed to balance baseline differences. Of the 24,962 patients, 498 were extubated in the OR. After matching, 487 OR extubation cases and 899 fast track cases were well balanced. The rate of reintubation was higher for patients extubated in the OR [21/487 (4.3%) vs 16/899 (1.8%), P = 0.008] as was the incidence of reoperation for bleeding [12/487 (2.5%) vs 8/899 (0.9%), P = 0.03]. There was no significant difference in the rate of any reoperation [16/487 (3.3%) vs 15/899 (1.6%), P = 0.06] or operative mortality [4/487 (0.8%) vs 6/899 (0.6%), P = 0.7]. OR extubation was associated with shorter hospital length of stay (5.6 vs 6.2 days, P < 0.001) and lower total cost of admission ($29,602 vs $31,565 P < 0.001). OR extubation is associated with a higher postoperative risk of reintubation and reoperation due to bleeding, but lower resource utilization.Future research exploring predictors of extubation readiness may be required prior to widespread adoption of this practice.

Emergency Tracheal Intubation in Patients with COVID-19: A Single-center, Retrospective Cohort Study.

INTRODUCTION: The objective of this study was to compare airway management technique, performance, and peri-intubation complications during the novel coronavirus pandemic (COVID-19) using a single-center cohort of patients requiring emergent intubation. METHODS: We retrospectively collected data on non-operating room (OR) intubations from February 1-April 23, 2020. All patients undergoing emergency intubation outside the OR were eligible for inclusion. Data were entered using an airway procedure note integrated within the electronic health record. Variables included level of training and specialty of the laryngoscopist, the patient's indication for intubation, methods of intubation, induction and paralytic agents, grade of view, use of video laryngoscopy, number of attempts, and adverse events. We performed a descriptive analysis comparing intubations with an available positive COVID-19 test result with cases that had either a negative or unavailable test result. RESULTS: We obtained 406 independent procedure notes filed between February 1-April 23, 2020, and of these, 123 cases had a positive COVID-19 test result. Residents performed fewer tracheal intubations in COVID-19 cases when compared to nurse anesthetists (26.0% vs 37.4%). Video laryngoscopy was used significantly more in COVID-19 cases (91.1% vs 56.8%). No difference in first-pass success was observed between COVID-19 positive cases and controls (89.4% vs. 89.0%, p = 1.0). An increased rate of oxygen desaturation was observed in COVID-19 cases (20.3% vs. 9.9%) while there was no difference in the rate of other recorded complications and first-pass success. DISCUSSION: An average twofold increase in the rate of tracheal intubation was observed after March 24, 2020, corresponding with an influx of COVID-19 positive cases. We observed adherence to society guidelines regarding performance of tracheal intubation by an expert laryngoscopist and the use of video laryngoscopy.

P2Y12 Inhibitor Monotherapy After a Short Dual Antiplatelet Therapy Versus Standard-Term Dual Antiplatelet Therapy in Patients Undergoing Percutaneous Coronary Intervention: A Contemporary Meta-Analysis.

BACKGROUND AND OBJECTIVES: Dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) reduces the incidence of thrombotic events but increases the risk of bleeding, which is associated with a substantial and durable risk of death and could offset the benefits of a reduction in thrombotic events. P2Y12 inhibitor monotherapy after short-term DAPT could be an option to reduce the risk of bleeding. We carried out a meta-analysis comparing P2Y12 inhibitor monotherapy after short-term DAPT with standard-term DAPT in patients undergoing PCI. METHODS: We searched the PubMed and EMBASE databases through 11 April 2020. Two authors independently reviewed and selected eligible trials. The DerSimonian-Laird method with the binary random-effects model was used to calculate the relative risk (RR) with 95% confidence interval (CI). RESULTS: Five trials involving 23,762 patients were included in the final analyses; four were open-label trials, while the TWILIGHT trial was double-blinded. Ticagrelor was used in three trials, and the other two trials included several P2Y12 inhibitors. P2Y12 inhibitor monotherapy after short-term DAPT significantly reduced the bleeding events, defined as Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding and Thrombolysis in Myocardial Infarction (TIMI) major or minor bleeding, by 39% (RR 0.61, 95% CI 0.38-0.99; p = 0.045) and 46% (RR 0.56, 95% CI 0.42-0.73; p < 0.001), respectively. A significant reduction in cardiovascular death was associated with P2Y12 inhibitor monotherapy after short-term DAPT (RR 0.75, 95% CI 0.58-0.98; p = 0.037; I2 = 0). No significant difference in all-cause mortality, myocardial infarction, stroke, or definite or probable stent thrombosis was observed. CONCLUSIONS: This meta-analysis showed a significantly lowered risk of major bleeding and similar benefits of P2Y12 inhibitor monotherapy after short-term DAPT compared with standard-term DAPT in patients undergoing PCI.

Unusual Soft Tissue Uptake of F-18 Sodium Fluoride in Three Patients Undergoing F-18 NaF PET/CT Bone Scans for Prostate Cancer.

Three males aged 71 to 80 years with known stage IV metastatic prostate cancer underwent F-18 sodium fluoride (NaF) PET/CT to assess osseous metastatic disease burden and stability. In addition to F-18 NaF avid known osseous metastases, each patient also exhibited increased F-18 NaF activity in soft tissues. The first patient exhibited multiple F-18 NaF avid enlarged retroperitoneal and pelvic lymph nodes on consecutive PET/CT scans. The second patient demonstrated an F-18 NaF avid thyroid nodule on consecutive PET/CT scans. The third patient exhibited increased F-18 NaF activity in a hepatic metastasis.

Pelvic osteomyelitis presenting as groin and medial thigh pain: a resident's case problem.

STUDY DESIGN: Resident's case problem. BACKGROUND: Groin pain represents a diagnostic challenge and requires a diagnostic process that rules out life-threatening illness or disease processes. Osteomyelitis is a potential fatal disease process that requires accurate diagnosis and medical management. Osteomyelitis presents a problem for the outpatient physical therapist, as the described physical findings for the diagnosis of osteomyelitis are nonspecific. DIAGNOSIS: A 67-year-old man with groin and bilateral medial thigh pain was referred for physical therapy care to address right adductor weakness and generalized deconditioning. He had undergone extensive treatment for bladder cancer, with a recent radical cystoprostatectomy and cutaneous urinary diversion with an Indiana pouch. Postsurgical magnetic resonance imaging indicated normal findings, and the patient was currently being managed by an orthopaedic surgeon, who diagnosed the patient as having obturator nerve palsy. The physical therapist's examination produced findings inconsistent with this diagnosis. Subsequently, nuclear medicine studies revealed pubic symphysitis/osteomyelitis with secondary myositis, predominantly affecting the right adductor muscles. DISCUSSION: Osteomyelitis represents a difficult problem for the outpatient physical therapist. Careful consideration of red-flag symptoms and inconclusive physical testing indicate the need for further medical work-up. In this case, appropriate medical management led to improvement in patient function, highlighting the need for early diagnosis. LEVEL OF EVIDENCE: Differential diagnosis, level 4.

Administration of subcutaneous buffered lidocaine prior to breast lymphoscintigraphy reduces pain without decreasing lymph node visualization.

UNLABELLED: Breast lymphoscintigraphy using (99m)Tc-sulfur colloid ((99m)Tc-SC) is well established in clinical practice for staging patients with breast carcinoma. Nearly all patients report having pain during the procedure. However, techniques used to minimize pain during breast lymphoscintigraphy are highly variable across institutions. Our study was to determine whether anesthetizing the skin with sodium bicarbonatehether-buffered lidocaine before performing breast lymphoscintigraphy reduced the pain experienced by the patients. The second objective of this study was to evaluate whether anesthetizing the skin with buffered lidocaine changed visualization of lymph nodes. METHODS: This prospective, patient-masked and randomized study involved performing breast lymphoscintigraphy in a control group and experimental group of female breast cancer patients. The control group did not receive skin anesthetic before (99m)Tc-SC injections, whereas the experimental group first underwent skin anesthesia with an injection of 2% sodium bicarbonate-buffered lidocaine. All patients were asked to rate their pain levels, using the National Institutes of Health pain scale, before the procedure and immediately after the injections. The change in pain from baseline was compared between the 2 groups. After the injections, scintigraphic imaging of the axilla was performed, and the number of axillary lymph nodes visualized was recorded. RESULTS: No significant difference was found in preprocedural baseline pain from the control group, compared with the experimental group. There was a statistically significant difference in the increase in pain experienced during the procedure between the control group and the experimental group (P = 0.009). There was no significant difference in the detection of lymph nodes between the control and experimental groups (P = 0.56). CONCLUSION: The results from our study indicate that injecting subcutaneous buffered lidocaine before intradermal injection of (99m)Tc-SC for breast lymphoscintigraphy significantly decreases patient pain without interfering with lymph node visualization.

Stress and coping in hospice nursing staff. The impact of attachment styles.

Previous research suggests that the attachment style developed during childhood informs adult attachment styles, which in turn affects adult relationships and responses to stress. This study considers the sources of stress in hospice nurses and addresses the potential impact of their attachment styles on stress and coping experiences. Adult attachment style, stress and coping were measured in 84 nurses recruited from five hospices. The results supported previous research regarding the most common sources of stress in this nursing group. The study found partial support for the hypothesis that nurses with insecure attachment styles experience more stress than securely attached nurses. Hospice nurses with a fearful or dismissing attachment style were found to be less likely to seek emotional social support as a means of coping with stress than hospice nurses with a secure or preoccupied attachment style. Supervision, support and career-long training for nurses in hospices are recommended. Further research is needed to clarify the involvement of attachment style in hospice nurse stress and coping experiences.
