Care in emergencies and disasters: Can it be person-centered?

OBJECTIVES: While person-/patient-centered care aims to influence policymakers' rules and regulations to improve the care of individuals worldwide, exploration of the concept in the context of disaster and public health emergencies as an alternative ethical approach is lacking. This study aims to provide a nuanced understanding of the advantages and challenges of diverse ethical approaches in emergencies, to improve patient care. METHODS: A survey, created after several rounds of Delphi methodology, with 22 statements, was applied to 39 participants from nine different countries. The questionnaire's results, including participants' comments, were analyzed. RESULTS: The results show that practitioners chose to use a combination of diverse ethical approaches in managing victims of disasters and public health emergencies. CONCLUSION: The selection of an approach is context- and situation-dependent and seems to primarily respond to the nature of underlying etiology, creating a possibility to use diverse approaches to offer individualized care on a later occasion and when a flexible surge capacity is available. PRACTICE IMPLICATIONS: The outcomes of this study will enhance the future ethical discussion in person/patient-centered care during situations with limited resources and help to develop necessary ethical and educational guidelines.

Expression of ethical principles in Australia's disaster plans.

OBJECTIVE: This qualitative study explores whether Australian mass casualty and disaster plans explicitly acknowledge or implicitly draw upon ethical principles. METHODS: Federal, state and territory governmental websites were searched to identify mass casualty incident and/or disaster plans. The authors examined the documents to identify whether ethical principles were overtly stated or implied, and what those values or principles were. RESULTS: Ten governmental documents were identified - two federal and one for each of the eight States and Territories. One of the documents had an explicit statement of the ethical values that informed the mass casualty and disaster planning decisions which were present. Utilitarianism was the dominant ethical principle informing the document in another seven documents. CONCLUSION: In Australian government documents for mass casualty and disaster management, although ethics is definitely considered, the ethical principles on which decisions are made are rarely explicit. Mass casualty and disaster decision-making could be improved by making the ethical basis for decision-making clear, transparent and comprehensively reasoned.

The impact of variations in care and complications within a colorectal Enhanced Recovery After Surgery program on length of stay.

PURPOSE: Enhanced Recovery After Surgery (ERAS) has become standard of care in colorectal surgery. However, there is not a universally accepted colorectal ERAS protocol and significant variations in care exist between institutions. The aim of this study was to examine the impact of variations in ERAS interventions and complications on length of stay (LOS). METHODS: This study was a single-center review of the first 200 consecutive patients recruited into our prospectively collected ERAS database. The primary outcome of this study was to examine the rate of compliance to ERAS interventions and the impact of these interventions on LOS. The secondary outcome was to assess the impact of complications (anastomotic leak, ileus, and surgical site infections) on LOS. ERAS interventions, rate of adherence, LOS, readmissions, morbidity, and mortality were recorded, and statistical analysis was performed. RESULTS: ERAS variations and complications significantly influenced patient LOS on both univariate and multivariate analysis. ERAS interventions identified as the most important strategies in reducing LOS included laparoscopic surgery, mobilization twice daily postoperative day (POD) 0 to 1, discontinuation of intravenous fluids on POD 0 to 1, upgrading to solid diet by POD 0 to 2, removal of indwelling catheter by POD 0 to 2, avoiding nasogastric tube reinsertion and removing drains early. Both major and minor complications increased LOS. Anastomotic leak and ileus were associated with the greatest increase in LOS. CONCLUSION: Seven high-yield ERAS interventions reduced LOS. Major and minor complications increased LOS. Reducing variations in care and complications can improve outcomes following colorectal surgery.

Emulating an RCT in observational research in chest trauma: The target trial approach.

BACKGROUND: While the concept of a "target trial"-optimizing the quality of observational studies by attempting to emulate the ideal world conditions of a randomized controlled trial-was first expounded over a decade ago, the take up of this concept in the design and analysis of trials in trauma is lacking. The target trial approach avoids common errors in observational research to increase its scientific validity as well as potentially enable causal questions to be answered without the expense and intricacies of a randomized controlled trial. This review article briefly introduces the reader to the concepts and utility of a "target trial" approach before providing demonstrations of its application in the subject area of chest trauma. METHODS: Four articles published in the last 5 years-two case control and two cohort studies-are chosen and considered in terms of their causal question; study population; inclusion and exclusion criteria; designation of time 0; clarity of the follow-up period; study outcomes; methods to minimize confounding; results; overall issues regarding study time; and the presence of avoidable errors such as introduction of immortal time bias or information bias. RESULTS: Two of the studies had an unclear causal question; none of the studies designated a time 0; the follow-up period was unclear for all but one of the studies; and one study had a serious issue with information bias resulting from differential misclassification. CONCLUSION: Failure to emulate a "target trial" framework may lead to serious methodologic issues in observational research. Expansion of the awareness of this approach in trauma literature will improve the quality of our observational research and potentially translate into significant benefits for our patients.

The swing shift: Opportunity to enhance trauma training in Australia.

BACKGROUND: Training in trauma forms a fundamental component of general surgical training in Australia. It faces a number of challenges, including the limitations of working hours and increasing use of non-operative management techniques. Adjustment of rosters to encompass a "swing shift" (12pm-midnight) is one proposed solution to maximise exposure of junior surgical doctors to trauma. This proposal prompted a review of the timing of major trauma presentations and interventions at a Level 1 trauma centre. METHODS: A retrospective observational study was performed of all major trauma presentations to Westmead Hospital, Australia over ten-years (2008-2017). Trauma operative procedures and major resuscitations were reviewed across three potential shifts: day shift (0730-1930), night shift (1930-0730) and "swing shift" (1200-midnight). Operative interventions included: laparotomy, thoracotomy/sternotomy, re-look laparotomy, rib fixation and tracheostomy. Descriptive statistics were obtained for between-shift comparisons. RESULTS: Over the ten-years there were 3745 full trauma team activations (FTTAs). The "swing shift" had the highest number of FTTAs, patients with injury severity scores >15, patients requiring resuscitation and emergency operations (laparotomies, sternotomies/thoracotomies). CONCLUSIONS: More major trauma calls, laparotomies and thoracotomies occurred during a theoretical "swing shift" rather than the standard day and night shifts. Changing trauma rostering for junior doctors to reflect this peak in clinical and operative demand could change exposure to trauma training.

Diagnostic laparoscopy in penetrating abdominal trauma.

BACKGROUND: Penetrating abdominal trauma is uncommon in Australia. There are multiple potential approaches to the patient without an indication for immediate laparotomy. This study examined the management of patients with a penetrating anterior abdominal injury in a Level 1 trauma centre, and in particular investigated the outcomes of those patients who underwent diagnostic laparoscopy. METHODS: A retrospective review was undertaken of all patients presenting to a Level 1 trauma centre with an anterior abdominal stab wound over a 15-year period. Patient demographic, injury, examination, treatment and outcome data were extracted. These data were analysed using SPSS PASW version 20. RESULTS: A total of 318 patients were identified. Immediate laparotomy was performed in 121 of those patients. Of the remaining 197 patients, 146 underwent diagnostic laparoscopy. Peritoneal breach was identified in 87 patients, 79 of whom then had exploratory laparotomy. The laparotomy was therapeutic in 36 of 79 patients (45.6%). Multiple stab wounds were an independent predictor of therapeutic laparotomy (hazard ratio 2.39, 95% CI 1.16-4.93). Diagnostic laparoscopy was 100% sensitive, 60.9% specific and had a negative predictive value of 100% and a positive predictive value of 40%. Non-therapeutic laparotomy was associated with a median length of stay of 5.5 days and a complication rate of 9.3%. CONCLUSION: Diagnostic laparoscopy to detect peritoneal breach is a safe approach in the management of anterior abdominal stab wounds. However, utilizing peritoneal breach as an indication for laparotomy is associated with a moderate incidence of non-therapeutic laparotomy. Measures to decrease the negative laparotomy rate should be considered.

The Modified Lateral Intercostal Artery Perforator Flap.

BACKGROUND: The main surgical options for treatment of breast cancer are breast-conserving surgery and mastectomy. BCS aims to achieve complete excision of the tumor while achieving a pleasing cosmetic result. Excision of tumors in the lateral aspect of the breast has been associated with issues such as contour deformities and asymmetry. Development of volume replacement techniques such as the lateral intercostal artery perforator flap (LICAP) aimed to address these issues. Our modification of the traditional LICAP offers a less visible scar, good access to the axilla, and no need to reposition the patient. METHODS: All patients undergoing a modified LICAP were identified from our database. The lateral intercostal artery perforators were marked with ultrasound and 2 "lazy S" lines were drawn to mark the flap. The wide local excision (with or without axillary surgery) was performed and the flap mobilized to fill the defect. RESULTS: Twenty-two patients underwent modified LICAP in 14 months. The mean specimen weight was 86 g. Four patients (18%) had a re-excision for positive margins. Nineteen patients had axillary surgery performed at the time of their modified LICAP flap. No patients had a scar that extended posterior to the posterior axillary line; no patients required a separate incision for axillary surgery; and no patients needed to be repositioned intraoperatively. CONCLUSIONS: Our early experience with this innovative procedure has been favorable. The perioperative complication rate is low. Due to the relatively short follow-up, longer term outcomes such as postradiotherapy appearance are yet to be determined.

Veritas in Immediate Implant-based Breast Reconstruction Is Associated with Higher Complications Compared with TiLOOP.

Biologic and synthetic meshes are used in immediate implant-based breast reconstruction for coverage of the lower pole of the implant. This study aimed to compare outcomes of Veritas with TiLOOP bra (TiLOOP group [TG]). METHODS: Retrospective study of skin- and nipple-sparing mastectomies in patients who underwent an implant-based reconstruction using either Veritas or TiLOOP bra between January 2014 and December 2016 was performed. RESULTS: Thirty-six reconstructions (22 unilateral, 7 bilateral) using the Veritas mesh and 179 breast reconstructions (61 unilateral, 59 bilateral) using TiLOOP bra were identified. The Veritas group (VG) showed a higher rate of postoperative complications compared with the TG (VG = 54% versus TG = 14%, P < 0.01%), including higher rates of seroma, nonintegration of mesh (VG = 51.4% versus TG = 1.6%, P < 0.01), implant rotation (VG = 16.2% versus TG = 1.6%, P < 0.01), infection (VG = 18.9% versus TG = 2.1%, P < 0.01), and wound breakdown (VG = 10.8% versus TG = 0.5%, P < 0.01). The VG also had a higher rate of major interventions (VG = 35.1% versus TG = 7.8%, P < 0.01) and minor interventions (VG = 18.9% versus TG = 2.2%, P < 0.01) compared with TG, including a higher rate of implant loss and unplanned return to theater. CONCLUSIONS: Veritas mesh was associated with a significantly higher rate of postoperative complications compared with TiLOOP bra. Our data strongly question the safety profile of Veritas in implant-based breast reconstruction. Further studies in this area are warranted.

Neoadjuvant systemic therapy for breast cancer: the Westmead experience.

BACKGROUND: Neoadjuvant systemic therapy (NAST) can be used to treat breast cancer. Pathologic complete response (pCR) is a surrogate marker for improved survival. This study examined response in the breast and axilla to NAST and identified features associated with pCR. METHODS: Patients undergoing NAST and surgery between January 2012 and June 2016 by surgeons at Westmead Breast Cancer Institute were identified. Patients with inflammatory or metastatic disease were excluded. Data were analysed to identify factors predictive of pCR. RESULTS: Ninety-one patients were identified. Mean age was 49 years. Forty-one patients had axillary metastases identified prior to NAST. Eighty-three patients received chemotherapy alone, six endocrine therapy alone and two had both. Thirty-seven patients had mastectomy and 54 had breast-conserving surgery. The overall breast pCR rate was 29% higher in patients with triple-negative (50%) or HER2-positive (39%) disease and lower in luminal disease (11.6%, P = 0.001). Forty percent of node-positive patients became node negative. The only variable associated with pCR was tumour biology. Patients with HER2-positive breast cancer were more likely to have axillary pCR than those with luminal cancer (odds ratio: 28, P = 0.00005). CONCLUSION: pCR in either the breast or axilla was most likely to be achieved in patients with HER2-positive or triple-negative breast cancers. In patients with luminal cancers, the goal of NAST is best considered to facilitate surgical options rather than obtaining a pCR.

Dual kidney transplant techniques: A systematic review.

BACKGROUND: Dual kidney transplantation (DKT) was developed to improve outcomes from transplantation of extended criteria donors (ECD). This study examined which surgical techniques have been reported for DKT and whether any technique had superior patient and graft survival. METHOD: Electronic databases were searched for published studies mapping to MESH terms: "kidney or renal" AND "transplan*" AND "dual or double." Single case reports, studies of patients less than 18 years old, studies which did not describe the surgical technique, and studies that did not report patient or graft survival were excluded. RESULTS: Fifteen reports of 434 DKT recipients were identified. Three techniques were described: bilateral placement; unilateral placement with separate anastomoses; and unilateral placement with patch anastomoses. Patient survival across all three techniques was over 95% at 1 year, and graft survival was also similar at over 90%. Rates of delayed graft function were between 20% and 30% across all techniques. CONCLUSION: The three techniques have equivalent delayed graft function as well as patient and graft survival rates. This is an encouraging result as it means that the surgeon can choose to use the technique which is most appropriate for their own skills and for the patient.
