Background: In an effort to reduce positive margins and subsequent re-excisions after breast conserving surgery (BCS), many providers utilize either a Full Cavity Shave (FCS) approach or intraoperative margin assessment using MarginProbe Radiofrequency Spectroscopy. Although both FCS and MarginProbe have been shown to reduce positive margins by ³50%, little has been reported about their economic impacts. We created a functioning Pro-Forma for use by facilities and payers to evaluate the cost-effectiveness of implementing FCS or MarginProbe. Methods: A decision tree demonstrating three possible surgical pathways, BCS, BCS+FCS, and BCS+MarginProbe was developed with clinical inputs for re-excision rate, rate of mastectomy conversion, and rate of breast reconstruction derived from literature review. A pathway cost formula was created using the decision tree and financial inputs derived from the nation’s largest database of private payor and Medicare claims data (fairhealth.org). This data was utilized to create a customizable Pro-Forma for cost-effectiveness analysis. Results: In the privately insured population, MarginProbe provides a cost-savings over BCS alone when baseline re-excision rates are over 20% and FCS becomes cost-saving when baseline re-excision rates are over 29%. For Medicare patients, MarginProbe provides a cost-savings when baseline re-excision rates exceed 34%, and FCS becomes cost-saving for re-excision rates over 52%. Conclusions: Utilizing either an FCS approach or the MarginProbe system may be cost-effective solutions to reducing breast re-excisions rates depending on surgical volume and baseline re-excision rates. The degree of cost effectiveness of these interventions for healthcare facilities and payers can be evaluated using the Pro-Forma outlined herein.

Background Neoadjuvant chemotherapy (NCT) is often used for patients with early-stage breast cancer. Disparities in the use of NCT based on clinical, demographic, and socioeconomic factors have not been evaluated. Methods Data from the National Cancer Database was analyzed for patients with T1-2, N0-1 breast cancer from 2006 to 2015. Univariate and multivariate analysis determined which factors predicted for the receipt of NCT. Results We found 159 946 eligible patients. Factors associated with receipt of NCT included T2 vs. T1 disease, N1 vs. N0, and treatment at an academic facility. Race itself was not significant; however, a higher level of education amongst Black populations correlated with the receipt of NCT. Discussion Clinical factors are the greatest determinants for receipt of NCT in early-stage breast cancer. Disparities exist that cannot be explained by race alone; socioeconomic and demographic factors are important. Cancer care should be evaluated in the context of the intersectionality of these health determinants.

Background Pediatric patients with severe refractory Crohn's colitis (CC) may require total colectomy (TC) or diverting loop ileostomy (DLI). Our understanding of outcomes (postoperative complications, nutrition and restoration of intestinal continuity) is currently limited. Methods Pediatric patients with severe CC who underwent TC or DLI were identified. Demographics, pre and postoperative anthropometric and biochemical data, surgical complications and medication requirements were recorded. Results Twenty-seven patients (TC=22, DLI=5) with a median age of 15.0years (range 3–18) were identified, 64% male with a median follow-up of 45months (range 3–120). Mean weight and BMI improved for TC patients by 1year postoperatively – weight z-score from −1.08 to −0.54 (p=0.02), BMI z-score from −0.83 to −0.38 (p=0.04), with a non-significant height change from - 0.79 to −0.65 (p=0.07). Mean hemoglobin and albumin both also improved - 9.88g/dl to 11.76g/dl (p=0.003) and 3.44g/dl to 4.03g/dl (p=0.004) respectively. These measures did not significantly improve after DLI. Most TC patients (59%) had attempted restoration of intestinal continuity with 45% in continuity at end of follow-up. One DLI patient underwent ileostomy takedown but subsequently needed re-diversion. Conclusions In severe CC, TC offers an opportunity to improve nutrition and growth, with a reasonable likelihood of restoring intestinal continuity. Level of evidence Level IV – Case series

Objective: To develop and provide validity and feasibility evidence for the QUality of Information Transfer (QUIT) tool. Background: Prompt escalation of care in the setting of patient deterioration can prevent further harm. Escalation and information transfer skills are not currently measured in surgery. Methods: This study comprised 3 phases: the development (phase 1), validation (phase 2), and feasibility analysis (phase 3) of the QUIT tool. Phase 1 involved identification of core skills needed for successful escalation of care through literature review and 33 semistructured interviews with stakeholders. Phase 2 involved the generation of validity evidence for the tool using a simulated setting. Thirty surgeons assessed a deteriorating postoperative patient in a simulated ward and escalated their care to a senior colleague. The face and content validity were assessed using a survey. Construct and concurrent validity of the tool were determined by comparing performance scores using the QUIT tool with those measured using the Situation-Background-Assessment-Recommendation (SBAR) tool. Phase 3 was conducted using direct observation of escalation scenarios on surgical wards in 2 hospitals. Results: A 7-category assessment tool was developed from phase 1 consisting of 24 items. Twenty-one of 24 items had excellent content validity (content validity index >0.8). All 7 categories and 18 of 24 (P < 0.05) items demonstrated construct validity. The correlation between the QUIT and SBAR tools used was strong indicating concurrent validity (r = 0.694, P < 0.001). Real-time scoring of escalation referrals was feasible and indicated that doctors currently have better information transfer skills than nurses when faced with a deteriorating patient. Conclusions: A validated tool to assess information transfer for deteriorating surgical patients was developed and tested using simulation and real-time clinical scenarios. It may improve the quality and safety of patient care on the surgical ward.

Objective: This study aimed to determine whether an intervention could improve the escalation of care skills of junior surgeons. Summary Background Data: Escalation of care involves the recognition, communication, and response to patient deterioration until a satisfactory outcome has been achieved. Although failure to escalate care can lead to increased morbidity and mortality, there is no formal training in how to perform this vital process safely. Methods: This randomized controlled trial recruited postgraduate year (PGY)-1 and PGY-2 surgeons to participate in 2 scenarios involving simulated patients requiring escalation of care. A control group performed both scenarios before receiving the intervention; the intervention group received the educational intervention before their second scenario. Scenarios were video recorded and rated by 2 independent, blinded assessors using validated scales to measure patient assessment, communication, management and nontechnical skills of participants, and the number of medical errors they detected. Results: A total of 33 PGY-1 and PGY-2 surgeons, all with equivalent skill at baseline, participated. Postintervention, the intervention group demonstrated significantly better patient assessment (P < 0.001), communication (P < 0.001), and nontechnical skills (P < 0.001). They also detected more medical errors (P < 0.05). Conclusions: Teaching junior surgeons a systematic approach to escalation of care improved multiple core skills required to maintain patient safety and avoid preventable harm.

Background Delays in escalation of care for patients may contribute to poor outcome. The factors that influence surgical patients’ willingness to call for help on wards are currently unknown. This study explored the factors that affect patients’ willingness to call for help on surgical wards; how patients call for help and to whom; how to encourage patients to call for help, and the barriers to patients calling for help. Methods A cross-sectional study was conducted in three London hospitals using a questionnaire designed through expert opinion and the published literature. A total of 155 surgical patients (83 % response rate) participated. Results Patients were more willing to call for help using the bedside buzzer or by calling a nurse compared to a doctor (p < 0.001). The prompts to calling for help patients were most likely to act on were bleeding and pain. Patients were more willing to call for help if encouraged by a healthcare professional than a relative or fellow patient (p < 0.01). Patients were more likely to worry about taking up too much time when calling for help than being perceived as difficult (p < 0.001). For some prompts, male patients were more willing to call for help (p < 0.05). Conclusions This is the first study to identify factors affecting patients’ willingness to call for help on surgical wards. Interventions that take these factors into account can be developed to encourage patients to call for help and may avoid delays in treatment.

Introduction\ud Impaction allograft with cement is a common technique used in revision hip surgeries for the last 20 years. However, its clinical results are inconsistent. Recent studies have shown that mesenchymal stem cells (MSCs) seeded onto allograft can enhance bone formation. This in vitro study investigates whether the increase in temperature related to the polymerisation of bone cement will affect the viability of human MSCs. \ud \ud Methods\ud The viability of human MSCs was measured after incubating them at temperatures of 38°C, 48°C and 58°C; durations 45 seconds, 80 seconds and 150 seconds. A control group was kept at 37°C and 5% carbon dioxide for the duration of the investigation (7 days). During the course of the study the human MSCs were analysed for cell metabolic activity using the alamarBlue™ assay, cell viability using both Trypan Blue dye exclusion and calcein staining under fluorescent microscopy, and necrosis and apoptosis using Annexin V and propidium iodide for flow cytometric analysis. A one-way analysis of variance with a priori Dunnett’s test was used to indicate the differences between the treatment groups, when analysed against the control. This identified conditions with a significant difference in cell metabolic activity (alamarBlue™) and cell viability (Trypan Blue). \ud \ud Results\ud Results showed that cell metabolism was not severely affected up to 48°C/150 seconds, while cells in the 58°C group died. Similar results were shown using Trypan Blue and calcein analysis for cell viability. No significant difference in apoptosis and necrosis of the cells was observed when human MSCs treated at 48°C/150 seconds were compared with the control group. \ud \ud Conclusions\ud The study suggests that human MSCs seeded onto allograft can be exposed to temperatures up to 48°C for 150 seconds. Exposure to this temperature for this time period is unlikely to occur during impaction allograft surgery when cement is used. Therefore, in many situations, the addition of human MSCs to cemented impaction grafting may be carried out without detrimental effects to the cells. Furthermore, previous studies have shown that this can enhance new bone formation and repair the defects in revision situations.
