Therapeutic Dilemma: Acute Myocardial Infarction in a Patient with Traumatic Hepatic and Mesenteric Injuries: A Case Report.

ST-elevation myocardial infarction (STEMI) in a trauma patient with solid abdominal organ or vascular injuries can present complex diagnostic and therapeutic challenges. Evidence for managing such demanding cases is scarce, and isolated case reports remain the source of information in treating these patients. We present a patient with traumatic mesenteric and hepatic injuries who developed acute STEMI in the immediate postoperative period.

Relational Work Is the Work: Virtual Healthcare Transformation for Rural, Remote and First Nations Communities in British Columbia.

The healthcare crisis across unceded First Nations' territories in rural, remote and Indigenous communities in British Columbia (BC) is marked by persistent barriers to accessing care and support close to home. This commentary describes an exceptional story of how technology, trusted partnerships and relationships came together to create an innovative suite of virtual care programs called "Real-Time Virtual Support" (RTVS). We describe key approaches, learnings and future considerations to improve the equity of healthcare delivery for rural, remote and First Nations communities. The key lessons include the following: (1) moving beyond a biomedical model - the collaboration framework for health service design incorporated First Nations' perspective on health and wellness; (2) relational work is the work - the RTVS collaboration was grounded in building connections and relationships to prioritize cultivating trust in the partnership over specific outputs; and (3) aligning to the core values of co-creation - working from a commitment to do things differently and applying an inclusive approach of engagement to integrate perspectives across different sectors and interest groups.

Real-time virtual supports improving health equity and access in British Columbia.

In British Columbia (BC) and across the territories of over 200 First Nations and 39 Métis Nation Chartered communities, the COVID-19 pandemic catalyzed a group of partner organizations to rapidly establish seven virtual care pathways under the Real-Time Virtual Support (RTVS) network. They aimed to address inequitable access and multiple barriers to healthcare faced by rural, remote, and Indigenous communities, and provide pan-provincial services. Mixed-method evaluation assessed implementation, patient and provider experience, quality improvement, cultural safety, and sustainability. Pathways supported 38,905 patient encounters and offered 29,544 hours of peer-to-peer support from April 2020 to March 2021. Mean monthly encounter growth was 178.0% (standard deviation = 252.1%). Ninety percent of patients were satisfied with the care experience; 94% of providers enjoyed delivering virtual care. Consistent growth suggests that the virtual pathways met the needs of providers and patients in rural, remote, and Indigenous communities, and supported virtual access to care in BC.

Imipenem/cilastatin/relebactam pharmacokinetics in critically ill patients with augmented renal clearance.

BACKGROUND: Imipenem and relebactam are predominantly excreted via glomerular filtration. Augmented renal clearance (ARC) is a common syndrome in critically-ill patients with sepsis, and sub-therapeutic antibiotic concentrations are of concern. Herein, we describe the pharmacokinetics of imipenem/relebactam in critically-ill patients with ARC. METHODS: Infected patients in the ICU with ARC (CLCR ≥ 130 mL/min) received a single dose of imipenem/cilastatin/relebactam 1.25 g as a 30 min infusion. Blood samples were collected over 6 h for concentration determination. Protein binding was assessed by ultrafiltration. An 8 h urine creatinine collection confirmed ARC. Population pharmacokinetic models with and without covariates were fit using the non-parametric adaptive grid algorithm in Pmetrics. A 5000 patient Monte Carlo simulation assessed joint PTA using relebactam fAUC/MIC ≥8 and imipenem ≥40% fT>MIC. RESULTS: Eight patients with ARC completed the study. A base population pharmacokinetic model with two-compartments fitted the data best. The mean ±â€ŠSD parameters were: CL, 17.31 ±â€Š5.76 L/h; Vc, 16.15 ±â€Š7.75 L; k12, 1.62 ±â€Š0.99 h-1; and k21, 3.53 ±â€Š3.31 h-1 for imipenem, and 11.51 ±â€Š4.79 L/h, 16.54 ±â€Š7.43 L, 1.59 ±â€Š1.12 h-1, and 2.83 ±â€Š2.91 h-1 for relebactam. Imipenem/cilastatin/relebactam 1.25 g as a 30 min infusion every 6 h achieved 100% and 93% PTA at MICs of 1 and 2 mg/L, respectively. CONCLUSIONS: Despite enhanced clearance of both imipenem and relebactam, the currently approved dosing regimen for normal renal function was predicted to achieve optimal exposure in critically-ill patients with ARC sufficient to treat most susceptible pathogens.

Evaluation of the safety of a novel peripheral vasopressor pilot program and the impact on central line placement in medical and surgical intensive care units.

PURPOSE: The purpose of this quality improvement project was to evaluate the safety and feasibility of peripheral vasopressor administration in an attempt to minimize the placement and improve early removal of unnecessary central lines to reduce central line-associated bloodstream infection (CLABSI) rates. METHODS: A retrospective chart review was conducted on patients who received vasopressors via peripheral infusion over 3 months, starting at the time of guideline implementation. RESULTS: We identified 129 vasopressor orders among 79 patients that were administered peripherally. Among these orders, 3 events were documented as possible extravasation events. Forty-five patients (57%) did not require central line placement due to increasing vasopressor requirements. Standard utilization ratio data suggest minimal central line impact of the protocol implementation. December 2020 to February 2021 was associated with a large second peak of coronavirus disease 2019 (COVID-19) in our region. Utilization of central lines was less than predicted in December 2020 to February 2021 in 2 of our 3 intensive care units (ICUs); however, the differences were statistically significant on only 3 occasions. In the third ICU, utilization was greater than predicted, but this unit housed a majority of the most critically ill patients with COVID-19. CONCLUSION: This study suggests that short-term use of select vasopressors at conservative doses is safe for peripheral administration and points toward efficacy at preventing central line placement. Further analysis is required to confirm efficacy.

Improving Decannulation and Swallowing Function: A Comprehensive, Multidisciplinary Approach to Post-Tracheostomy Care.

BACKGROUND: Multidisciplinary tracheostomy teams have been successful in improving operative outcomes; however, limited data exist on their effect on postoperative care. We aimed to determine the effectiveness of a multidisciplinary tracheostomy service alone and following implementation of a post-tracheostomy care bundle on rates of decannulation and tolerance of oral diet before discharge. METHODS: Prospective data on all subjects requiring tracheostomy by any trauma/critical care surgeon were collected from January 2011 to December 2013 following development of a tracheostomy service and continued following implementation of the post-tracheostomy care bundle. Rates of decannulation and tolerance of oral diet were compared between all groups: pre-tracheostomy service (baseline, historical control), tracheostomy service alone, and tracheostomy service with post-tracheostomy care bundle. RESULTS: Three hundred ninety-three subjects met the criteria for analysis with 61 in the baseline group, 124 following initiation of a tracheostomy service, and 208 after the addition of the post-tracheostomy care bundle. There were significant overall differences between all groups in the proportion of subjects decannulated, proportion of subjects tolerating oral diet, and number of subjects receiving speech evaluations. Pairwise comparisons showed no differences in decannulation or tolerance of oral diet following implementation of the tracheostomy service alone but significant improvement with the addition of the post-tracheostomy care bundle compared with baseline. (P = .002 and P = .005, respectively). Likewise, the number of speech language pathologist consults significantly increased compared with baseline only after the post-tracheostomy care bundle (P = .004). Time to speech evaluation significantly decreased with the post-tracheostomy care bundle compared with baseline and tracheostomy service (P < .013). CONCLUSIONS: The addition of a post-tracheostomy care bundle to a multidisciplinary tracheostomy service significantly improved rates of decannulation and tolerance of oral diet.

Simulation training in critical care: does practice make perfect?

BACKGROUND: Few data exist regarding the effectiveness of simulation in resident education in critical care. The purpose of this study was to determine whether multiple-simulation exposure (MSE) or single-simulation exposure (SSE) improved residents' recognition of shock and initial management of the critically ill simulated surgical patient. METHODS: Data were collected at a level 1 trauma center. Surgery, anesthesiology, and emergency medicine residents were given a multiple-choice question (MCQ) pretest before a tutorial on the recognition and management of shock followed by high-fidelity simulation/debriefing and MCQ post-test. MSE residents had 1.5 hours of simulation per resident over 3 days, and SSE residents had 1.5 hours of simulation as a group in 1 day. Pre- and posttest comparisons overall and subgroup analysis for MSE versus SSE were performed. RESULTS: Data was available for 45 MSE residents and 15 SSE residents. Overall posttest percent correct was greater than pretest percent correct (81% ± 9% vs 75% ± 13%, post- versus pre-, P = .01). Subgroup analysis demonstrated significantly improved post- versus pretest performance for MSE residents only. There were no differences in pre- or posttest performance for MSE residents during the first 4 months of the academic year versus the last 4 months. Pretest performance over 12 months of observation for MSE residents showed no significant differences. CONCLUSION: Repeated simulation exposure was more effective than single simulation exposure at improving MCQ performance designed to measure the recognition and management of shock in the critically ill simulated surgical patient. Duration of training did not impact MCQ performance.

Resource-efficient mobilization programs in the intensive care unit: who stands to win?

BACKGROUND: Functional outcomes can improve with early intensive care unit (ICU) mobilization programs but require additional resources. Details regarding resource allotment and methods to deliver therapy are lacking. We describe an effective team-based, resource-efficient mobility program (REMP). METHODS: Consecutive admissions (November 2009 to March 2010) underwent an evaluation by a physical therapist and participation in the REMP. Sitting balance (SB), transfer from bed to chair, and ambulation were assessed on the initial evaluation and compared with ICU and hospital discharge using the Functional Independence Measure scale. RESULTS: Twenty-eight patients entered the REMP, and 31 patients served as controls. There were no differences in baseline characteristics or initial Functional Independence Measure scores for ambulation or SB. Bed-to-chair evaluation was higher in the controls (P < .024). Both groups improved across the 3 time periods on all measures; however, more REMP patients had a significantly improved SB at ICU and hospital discharge. CONCLUSIONS: A team-based, resource-efficient approach to early mobilization is feasible and effective in the ICU.

Web-based teaching module improves success rates of postpyloric positioning of nasoenteric feeding tubes.

BACKGROUND: Bedside protocols improve success rates of postpyloric nasoenteric tube (NET) placement by nutrition teams and experienced individuals. However, many hospitals require novice practitioners to perform these procedures and often choose fluoroscopy, endoscopy, or newer alternative devices to achieve success. Little is known about the ability to train inexperienced practitioners or the effectiveness of the methods used to implement these protocols. Web-based learning is a potential tool to improve knowledge and procedural skills. The authors created a self-directed Web-based teaching module (WBTM) to educate and standardize placement of postpyloric NETs. METHODS: Forty-three first-, second-, or third-year residents or medical or physician assistant students took pretests for knowledge and confidence surveys, viewed the WBTM, placed NET at the bedside, then took a posttest and confidence survey while awaiting confirmation of tube position by abdominal radiograph. Success was acknowledged if the tip of the NET was beyond the pylorus. A retrospective chart review was used to determine a historical success rate, which was used as a control. RESULTS: Knowledge and confidence significantly improved. Overall success rate of postpyloric NET placement for all participants on first attempt was 74.4% vs 46.7% in the control (P = .005). Improvement occurred in all subgroups, including those with no prior experience, who were successful 70.4% of the time (P = .009). CONCLUSIONS: This WBTM is simple to implement, inexpensive, and resource efficient. The improvement in postpyloric NET placement, especially among novice practitioners, demonstrates the benefit and applicability of this method of standardized education.

Fecal containment in bedridden patients: economic impact of 2 commercial bowel catheter systems.

BACKGROUND: Fecal contamination is a major challenge in patients in acute/critical care settings that is associated with increased cost of care and supplies and with development of pressure ulcers, incontinence dermatitis, skin and soft tissue infections, and urinary tract infections. OBJECTIVES: To assess the economic impact of fecal containment in bedridden patients using 2 different indwelling bowel catheters and to compare infection rates between groups. METHODS: A multicenter, observational study was done at 12 US sites (7 that use catheter A, 5 that use catheter B). Patients were followed from insertion of an indwelling bowel catheter system until the patient left the acute/critical care unit or until 29 days after enrollment, whichever came first. Demographic data, frequency of bedding/dressing changes, incidence of infection, and Braden scores (risk of pressure ulcers) were recorded. RESULTS: The study included 146 bedridden patients (76 with catheter A, 70 with catheter B) who had similar Braden scores at enrollment. The rate of bedding/dressing changes per day differed significantly between groups (1.20 for catheter A vs 1.71 for catheter B; P = .004). According to a formula that accounted for personnel resources and laundry cycle costs, catheter A cost $13.94 less per patient per day to use than did catheter B. Catheter A was less likely than was catheter B to be removed during the observational period (P = .03). Observed infection rates were low. CONCLUSION: Catheter A may be more cost-effective than catheter B because it requires fewer unscheduled linen changes per patient day.

Mannequin simulation identifies common surgical intensive care unit teamwork errors long after introduction of sepsis guidelines.

INTRODUCTION: Groups of evidence-based guidelines were developed into a comprehensive treatment bundle as part of an international-based Surviving Sepsis Campaign to improve treatment of severe sepsis and septic shock. Conventional educational strategies of this sepsis treatment "bundle" may not ensure acceptable knowledge or completion of these specific tasks and may overlook other dynamic factors present during critical moments of a crisis. Simulation using multidisciplinary teams of clinicians through mannequin-based simulations (MDMS) may improve "bundle" compliance by identifying sepsis guideline errors, reinforcing knowledge, and exposing other potential causes of poor performance. METHODS: Seventy-four clinicians participated in the MDMS 14 months after hospital-wide introduction of the sepsis bundle. Additionally, each team was given a sepsis treatment-learning packet before the training session. Twelve teams underwent a MDMS of a patient in septic shock. Two evaluators recorded completed sepsis guideline tasks in real time. Sessions were videotaped and reviewed with the team in a postscenario debriefing session. Pre/posttests were also administered. RESULTS: Individual participants' pretest scores averaged 64.6% correct. Despite all but one team having at least one knowledgeable member with a pretest score of at least 80%, team task completion averaged only 60.4%. Team mean pretest scores and proportion of tasks completed were significantly correlated (P = 0.007), but correlations between specific tasks and related questions showed no relationship to knowledge. CONCLUSION: Inadequate completion of the sepsis guideline tasks during the MDMS could not be explained by inadequate pretest knowledge alone. MDMS may be a useful tool in identifying and exploring these unknown factors.

Midlevel practitioner workforce analysis at a university-affiliated teaching hospital.

OBJECTIVE: To quantify midlevel practitioner (MLP) staffing requirements based on the volume and complexity of patient care and the duty-hour constraints of the Accreditation Council for Graduate Medical Education 80-hour workweek. DESIGN: Data extracted from Eclipsys Sunrise Decision Support Manager, the hospital financial budget, and census reports; and MLP, resident, and subspecialty fellow clinical, operative, and on-call schedules, and educational curriculum. Fiscal year 2005 patient census and hours of required care were defined by attending physician service and/or patient care location. Volume of patient care activity for MLPs, residents, and subspecialty fellows were established by verified self-reporting methodology. SETTING: Urban teaching hospital with 867 beds, of which 116 are surgical beds (which include 36 intensive care unit beds and 12 step-down beds). PARTICIPANTS: Attending physicians, MLPs, residents, and subspecialty fellows. MAIN OUTCOME MEASURES: Coverage index (available staffing hours [residents, subspecialty fellows, and MLPs] divided by the clinical coverage schedule), and the workload staffing efficiency index (number of clinical hours of patient care activities divided by the hours of available staff for a specific clinical service). RESULTS: The workload staffing efficiency index and the coverage index identified 4 services that benefited from the addition of new MLPs. CONCLUSION: We developed a quantitative MLP staffing methodology based on patient volume and the type and complexity of direct and indirect patient care activities, encompassing the roles and availability of residents, subspecialty fellows, and MLPs.
