Surgical Trainees and The Geriatric Patient: A Scoping Review.

OBJECTIVE: There is an increasing emphasis on surgical trainees learning how to appropriately provide care for the geriatric patient. We hypothesized that little published formal curriculum on the topic exists. We sought to perform a scoping review to test this hypothesis. DESIGN: PubMed, OVID Medline, and EMBASE databases were queried from inception, supplemented by hand search of references and the grey literature. Included English language abstracts and articles described trainee perceptions of geriatric patients and/or description of dedicated geriatric curricula for trainees. RESULTS: There were 21 included abstracts or papers, which were categorized into 8 survey-based studies, 6 descriptions of curricular design, and 7 interventional studies with pre- and post-intervention knowledge tests. General surgery residents were most frequently included. Self-rated confidence and comfort were typically higher than objective measures of resident performance in the care of geriatric patients. Residents were commonly unaware of the standardized assessment tools and recommendations that exist. Medication and delirium management were frequently-identified topics posing the widest gaps in resident knowledge. CONCLUSION: There are few published examples of curricula on the care of geriatric patients for surgical trainees. More work is needed for the creation of specialty-specific and needs-based geriatric surgical curricula.

Critical decisions in the trauma intensive care unit: Are we practicing primary palliative care?

BACKGROUND: Devastating injuries require both urgent assessment by a trauma service and early attention to patients' goals of care (GOC). American College of Surgeons Trauma Quality Improvement Program (TQIP) guidelines recommend an initial palliative assessment within 24 hours of admission and family meeting, if needed, within 72 hours. We hypothesize that a primary palliative care-based practice improves adherence to TQIP guidelines in trauma patients. METHODS: All adult trauma patients who died while inpatient from January 2014 to December 2018 were reviewed. Timing of GOC discussions, transition to comfort measures only (CMO), and the utilization of specialty palliative services were analyzed with univariate analysis. RESULTS: During the study period, 415 inpatients died. Median Injury Severity Score was 26 (interquartile range [IQR], 17-34), median age was 67 years (IQR, 51-81 years), and 72% (n = 299) transitioned to CMO before death. Documented GOC discussions increased from 77% of patients in 2014 to 95% of patients in 2018 (p < 0.001), and in 2018, the median time to the first GOC discussion was 15 hours (IQR, 7- 24 hours). Specialty palliative care was consulted in 7% of all patients. Of patients who had at least one GOC discussion, 98% were led by the trauma intensive care unit (TICU) team. Median time from admission to first GOC discussion was 27 hours (IQR, 6-91 hours). Median number of GOC discussions was 1 (IQR, 1-2). Median time to CMO after the final GOC discussion was 0 hours (IQR, 0-3). Median time to death after transition to CMO was 4 hours (IQR, 1-18 hours). CONCLUSION: Of those who died during index admission, we demonstrated significant improvement in adherence to American College of Surgeons TQIP palliative guidelines across the 5-year study period, with the TICU team guiding the majority of GOC discussions. Our TICU team has developed an effective primary palliative care approach, selectively consulting specialty palliative care only when needed. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

Massive transfusions and severe hypocalcemia: An opportunity for monitoring and supplementation guidelines.

BACKGROUND: Massive transfusion protocols (MTPs) are associated with severe hypocalcemia, contributing to coagulopathy and mortality in severely injured patients. Severity of hypocalcemia following massive transfusion activation and appropriate treatment strategies remain undefined. STUDY DESIGN AND METHODS: This was a retrospective study of all MTP activations in adult trauma patients at a Level 1 trauma center between August 2016 and September 2017. Units of blood products transfused, ionized calcium levels, and amount of calcium supplementation administered were recorded. Primary outcomes were ionized calcium levels and the incidence of severe ionized hypocalcemia (iCa ≤1.0 mmol/L) in relation to the volume of blood products transfused. RESULTS: Seventy-one patients had an MTP activated during the study period. The median amount of packed red blood cells (PRBCs) transfused was 10 units (range 1-52). A total of 42 (59.1%) patients had periods of severe hypocalcemia. Patients receiving 13 or more units of PRBC had a greater prevalence of hypocalcemia with 83.3% having at least one measured ionized calcium ≤1.0 mmoL/L (p = .001). The number of ionized calcium levels checked and the amount of supplemental calcium given in patients who experienced hypocalcemia varied considerably. DISCUSSION: Severe hypocalcemia commonly occurs during MTP activations and correlates with the number of packed red blood cells transfused. Monitoring of ionized calcium and amount of calcium supplementation administered is widely variable. Standardized protocols for recognition and management of severe hypocalcemia during massive transfusions may improve outcomes.

Mitigating Burnout.

Burnout is characterized by emotional exhaustion, depersonalization, and a reduced sense of personal accomplishment. All physicians, and especially surgeons, are at risk for developing burnout. The best strategies for mitigating burnout mimic a modern approach to medicine: the development of preventive practices to protect, promote, and maintain health and well-being. Job satisfaction, job engagement, and compassion satisfaction help protect from burnout. Individual commitment to self-care in conjunction with support from within health care organizations create the optimal framework in which burnout can be mitigated.

Increased hepatic blood flow during enteral immune-enhancing diet gavage requires intact enterohepatic bile cycling.

OBJECTIVES: Total hepatic blood flow (HBF) via the hepatic artery and portal vein is highly dependent on gastrointestinal perfusion. During postprandial hyperemia, intestinal blood flow depends on nutrient composition, gastrointestinal location, and time. Immune-enhancing diets (IEDs) containing n-3 polyunsaturated fatty acids (PUFAs) selectively augment blood flow in the ileum at 60-120 min via a bile-dependent mechanism. My colleagues and I hypothesized that liver blood flow would be similarly affected by IEDs containing n-3 PUFAs. METHODS: Mean arterial blood pressure, heart rate, and effective HBF (galactose clearance) were measured in anesthetized male Sprague-Dawley rats after gastric gavage of either a control diet (CD, Boost, Novartis) or an IED (Impact, Nestle Nutrition), with or without bile-duct ligation (BDL), and with or without supplemental bile (bovine, dried, unfractionated). Significance was assessed by 2-way ANOVA for repeated measures with the Tukey-Kramer honestly significant difference test. RESULTS: Compared with baseline levels, a CD increased HBF (peak at 40 min , *P < 0.05) whereas an IED increased HBF in two distinct peaks at 40 min (*P < 0.05) and 120 min (*P < 0.05), but BDL prevented both the early (CD and IED, †P < 0.05) and late peaks (IED, †P < 0.05). Bile supplementation in the CD + BDL or IED + BDL groups restored neither the CD peak nor the early or late IED peaks. CONCLUSIONS: HBF during absorptive intestinal hyperemia is modulated by a mechanism that requires an intact enterohepatic circulation. The early peaks at 40 min (CD or IED) were prevented by BDL, even though fat absorption in the proximal gut occurs by bile-independent direct absorption. Bile supplementation with the diet (CD + BDL or IED + BDL) was insufficient to restore HBF hyperemia, which implies that a relationship exists between intestinal and hepatic blood flow that is not solely dependent on bile-mediated intestinal fat absorption and bile recirculation.
