Interprofessional Education Module on Post-Intensive Care Syndrome for Internal Medicine Residents.

Background: Prevention of post-intensive care syndrome (PICS) in critically ill patients requires interprofessional collaboration among physicians, physical therapists, occupational therapists, speech-language pathologists, and nutritionists. Interprofessional education promotes interprofessional collaborative practice, yet formalized interprofessional education during residency is uncommon. Objective: We sought to improve internal medicine residents' knowledge of interprofessional roles in the intensive care unit (ICU) and confidence in managing PICS by designing a virtual multimodal training module. Methods: We created a 3-hour virtual module with physical therapy, occupational therapy, speech-language pathology, and nutrition experts. First, learners reviewed PICS and multidisciplinary interventions to optimize patient recovery. Second, attendees watched videos created by physical therapy and occupational therapy colleagues demonstrating mobility strategies to manage ICU-acquired weakness and delirium. Third, participants learned how speech-language pathology experts evaluate and manage swallowing disorders. Finally, attendees identified common nutritional therapy challenges with a trivia session. Participants completed pre- and postcourse assessments. Results: Thirty-four residents completed both pre- and postcourse assessments (52% response rate). The mean objective assessment score improved from 51% to 79% (P < 0.001). All respondents reported that their knowledge of PICS increased, and almost all (97%) believed that their knowledge of interprofessional roles increased. Respondents' confidence in facilitating discussions about critical illness recovery significantly improved, from 77% rating as either not very confident or not at all confident before the course to 94% rating as somewhat confident or very confident after the course (P < 0.001). Conclusion: This single-site pilot study suggests that integrating interprofessional training in PICS education using virtual platforms may improve residents' knowledge of interprofessional roles in the ICU and confidence in managing PICS.

Increasing Enteral Protein Intake in Critically Ill Trauma and Surgical Patients.

BACKGROUND: Published guidelines recommend providing at least 2 g/kg/d of protein for critically ill surgical patients. It may be difficult to achieve this level of intake using standard enteral formulas, thus necessitating protein or amino acid supplementation. Herein, we report our approach to enteral protein supplementation and its relationship with urinary nitrogen excretion and serum transthyretin concentrations. METHODS: This was a retrospective cohort study in which we reviewed critically ill trauma and surgical patients treated with supplemental enteral protein according to a protocol aiming to deliver a total of 2 g/kg/d of protein. We collected detailed nutrition data over a 2-week period after admission and obtained additional data through discharge to determine caloric and protein intake as well as complications. We also compared urine nitrogen excretion and transthyretin concentrations between these patients and a control group who did not receive supplemental protein. RESULTS: Fifty-three subjects received early protein supplementation. Formula and protein supplement each provided ≈1.2 g/kg/d of protein by intensive care unit day 4. This resulted in a median total protein intake of 2.2 g/kg/d through day 14. One patient developed acute kidney injury, and 1 patient had 3 episodes of vomiting. By the third week, serum transthyretin concentrations increased to a median of 21 mg/dL compared with 13 mg/dL in subjects not receiving early supplementation. CONCLUSION: It is safe to deliver supplemental protein enterally to critically ill surgical and trauma patients and reach 2 g/kg/d of protein intake during the first week of illness.

Parenteral Nutrition Utilization After Implementation of Multidisciplinary Nutrition Support Team Oversight: A Prospective Cohort Study.

BACKGROUND: Multidisciplinary nutrition teams can help guide the use of parenteral nutrition (PN), thereby reducing infectious risk, morbidity, and associated costs. Starting in 2007 at Harborview Medical Center, weekly multidisciplinary meetings were established to review all patients receiving PN. This study reports on observed changes in utilization from 2005-2010. MATERIALS AND METHODS: All patients who received PN from 2005-2010 were followed prospectively. Clinical data and PN utilization data were recorded. Patients were grouped into cohorts based on exposure to weekly multidisciplinary nutrition team meetings (from 2005-2007 and from 2008-2010). Patients were also stratified by location, primary service, and ultimate disposition. RESULTS: In total, 794 patients were included. After initiation of multidisciplinary nutrition meetings, the rate of patients who started PN decreased by 27% (relative risk [RR], 0.73; 95% confidence interval [CI], 0.63-0.84). A reduction in the number of patients receiving PN was observed in both the intensive care unit (ICU) and on the acute care floor (RR, 0.64; 95% CI, 0.53-0.77 and RR, 0.80; 95% CI, 0.64-0.99, respectively). The rate of patients with short-duration PN use (PN duration of <5 days) declined by 30% in the ICU (RR, 0.70; 95% CI, 0.51-0.97) and by 27% on acute care floors (RR, 0.73; 95% CI, 0.51-1.03). CONCLUSIONS: Weekly multidisciplinary review of patients receiving PN was associated with reductions in the number of patients started on PN, total days that patients received PN, and number of patients who had short-duration (<5 days) PN use.

New paradigm in nutrition support: using evidence to drive practice.

Adequate nutrition support is a key component in achieving favorable outcomes for the critically ill patient. Significant evidence supports starting enteral nutrition rather than parenteral nutrition as early as possible after injury to promote positive outcomes. Evidence shows that enteral nutrition improves patient outcomes and decreases intensive care unit length of stay by improving splanchnic blood flow, moderating the metabolic response, sustaining gut integrity, and preventing bacterial translocation from the gut to the bloodstream. Implementing early enteral nutrition can be challenging. This article describes the rationale for early enteral nutrition, the evidence that favors enteral nutrition over parenteral nutrition, barriers to delivery of full enteral nutrition, and an evidence-based protocol developed at Harborview Medical Center to promote appropriate support. The role of the registered dietitian on the health care team in facilitating appropriate feeding is discussed. In addition, we will describe emerging nutrition therapies including the use of antioxidants, addition of the amino acid glutamine, use of immune-enhancing enteral formulas, and the potential role of probiotics that show promise in improving patient outcome.

The risk for bloodstream infections is associated with increased parenteral caloric intake in patients receiving parenteral nutrition.

BACKGROUND: Patients receiving total parenteral nutrition (TPN) are at high risk for bloodstream infections (BSI). The notion that intravenous calories and glucose lead to hyperglycemia, which in turn contributes to BSI risk, is widely held but is unproven. We therefore sought to determine the role that hyperglycemia and parenteral calories play in the development of BSI in hospitalized patients receiving TPN. METHODS: Two hundred consecutive patients initiated on TPN between June 2004 and August 2005 were prospectively studied. Information was collected on patient age, sex, admission diagnosis, baseline laboratory values, intensive care unit (ICU) status and indication for TPN. Patients in the ICU were managed with strict glycemic control, whereas control on the general ward was more liberal. The maximum blood glucose level over each 8-hour period was recorded, as were parenteral daily intake, enteral daily intake and total daily caloric intake. The primary outcome measure was the incidence of BSI. Additional endpoints were ICU length of stay, hospital length of stay and mortality. RESULTS: A total of 78 patients (39%) developed at least one BSI, which were more common in ICU patients than in other hospitalized patients (60/122 patients versus 18/78 patients; P < 0.001). Maximum daily blood glucose concentrations were similar in patients with BSI and in patients without BSI (197 mg/dl versus 196 mg/dl, respectively). Patients with BSI received more calories parenterally than patients without BSI (36 kcal/kg/day versus 31 kcal/kg/day, P = 0.003). Increased maximum parenteral calories, increased average parenteral calories, and treatment in the ICU were strong risk factors for developing BSI. There was no difference in mortality between patients with and without BSI. CONCLUSION: Increased parenteral caloric intake is an independent risk factor for BSI in patients receiving TPN. This association appears unrelated to hyperglycemia. Based upon our observations, we suggest that parenteral caloric intake be prescribed and adjusted judiciously with care taken to account for all intravenous caloric sources and to avoid even short periods of increased intake.
