Outcomes of parenteral nutrition in patients with advanced cancer and malignant bowel obstruction.

BACKGROUND: Malignant bowel obstruction (MBO) affects 3% to 15% of all cancer patients. In patients with advanced cancer and inoperable MBO, the average survival varies between four to nine weeks. Parenteral nutrition (PN) may improve survival in specific patient populations with malignant bowel obstruction. AIMS: This retrospective, single-center cohort study aimed to review individual patient outcomes on PN in the setting of advanced cancer with a diagnosis of MBO and identify clinical and laboratory markers predictive of short- and long-term survival to further highlight patients that would benefit from PN in the setting of an inoperable MBO. RESULTS: In a retrospective analysis of 68 patients receiving PN for inoperable MBO, the median survival was 142 (IQR: 63.3-239.5) days. Patients experienced a median number of two hospital readmissions (range: 0-10) and spent a median of 29 days (range: 0-105) in the hospital after starting PN. Eighteen (26.5%) patients developed a catheter-related bloodstream infection (CRBSI). A diagnosis of appendiceal cancer was identified as a predictive marker of improved survival (HR: 0.53, 95% CI: 0.29-0.92, p = 0.023). CONCLUSIONS: The use of PN in the context of end-of-life cancer care is a practice that necessitates improvement. Recognizing the outcomes and patient experiences of PN utilization is essential to physicians and patients.

Real-World Management of High Stool Output in Patients with Short Bowel Syndrome: An International Multicenter Survey.

BACKGROUND: International practice guidelines for high-stool-output (HSO) management in short bowel syndrome (SBS) are available, but data on implementation are lacking. This study describes the approach used to manage HSO in SBS patients across different global regions. METHODS: This is an international multicenter study evaluating medical management of HSO in SBS patients using a questionnaire survey. Thirty-three intestinal-failure centers were invited to complete the survey as one multidisciplinary team. RESULTS: Survey response rate was 91%. Dietary recommendations varied based on anatomy and geographic region. For patients without colon-in-continuity (CiC), clinical practices were generally consistent with ESPEN guidelines, including separation of fluid from solid food (90%), a high-sodium diet (90%), and a low-simple-sugar diet (75%). For CiC patients, practices less closely followed guidelines, such as a low-fat diet (35%) or a high-sodium diet (50%). First-line antimotility and antisecretory medications were loperamide and proton-pump inhibitors. Other therapeutic agents (e.g., pancreatic enzymes and bile acid binders) were utilized in real-world practices, and usage varied based on intestinal anatomy. CONCLUSION: Expert centers largely followed published HSO-management guidelines for SBS patients without CiC, but clinical practices deviated substantially for CiC patients. Determining the reasons for this discrepancy might inform future development of practice guidelines.

A multidisciplinary team evaluation of management guidelines for adult short bowel syndrome.

BACKGROUND & AIMS: An international, multidisciplinary management working group (MWG) convened to review clinically useful short bowel syndrome (SBS) literature and identify gaps and inconsistencies in the management of adults with SBS. METHODS: Using nominal group technique for literature review, key publications were identified, discussed, and ranked by importance related to management of SBS. Gaps in management recommendations for SBS were identified upon critical review of the selected publications. RESULTS: Five guidelines, seven review articles, one series of six articles, and one single center series were selected and prioritized for their importance to SBS management. Evaluation of the articles by the MWG identified ten gaps and opportunities to standardize and improve SBS management. CONCLUSION: The main practice areas in need of more definitive guidelines are the management of high stool output and strategies to improve absorption of medications, nutrients, and fluids. An understanding of current real-world clinical practices related to these gaps could allow for development of best practice standards and improve patient-focused care.

Characteristics of adult intestinal failure centers: An international multicenter survey.

BACKGROUND: Current guidelines recommend that patients with chronic intestinal failure (CIF) should be managed by a multidisciplinary team (MDT). However, the characteristics of real-world IF centers and the patients they care for are lacking. The study aims to describe IF center characteristics as well as characteristics of patients with CIF across different global regions. METHODS: This is an international multicenter study of adult IF centers using a survey. The questionnaire survey included questions regarding program and patient characteristics. Thirty-three investigational centers were invited to participate. Each center was asked to answer the survey questions as one MDT. RESULTS: The survey center response rate was 91%. The median number of patients with CIF per center was 128 (range, 30-380). The most common disciplines reported were gastroenterologist (93%), dietitian (90%), nurse (83%), and advanced practitioner (nurse practitioner and physician assistant, 77%). There were centers that did not have a pharmacist, surgeon, psychologist, and social worker (30%, 37%, 60%, and 70%, respectively). The median full-time equivalents (FTEs) per 100 patients were 1.1 for nurses, 1 for dietitians, 1 for advanced practitioners, and 0.9 for gastroenterologists. Short bowel syndrome was the most common cause of CIF (50%) followed by intestinal dysmotility (20%). CONCLUSION: The majority of centers were managing around 100 patients with CIF. Despite the widespread use of the MDT, there are some variances in team characteristics. Gastroenterologists were the most common physicians supporting MDTs. In IF centers, one FTE of each core discipline was supported to manage 100 patients with CIF.

Safe care transitions for patients receiving parenteral nutrition.

Transitions of care require coordination between inpatient healthcare providers, care managers, outpatient/ambulatory providers, and the patient/caregiver and family members. Poor communication during transitions of care can affect health outcomes and economic costs for patients/caregivers, healthcare providers, and healthcare systems. The goal of this paper is to identify risk-prone processes in the transition of care for patients requiring parenteral nutrition (PN) between healthcare environments, including the hospital, home, skilled nursing facility, and long-term acute care hospital settings. To facilitate the evaluation of the transition, a sequential series of steps in the transition process were identified: initial notification, assessment in preparation for transfer, identifying the receiving organization, identifying accountable providers at each sending/receiving organization, communicating the nutrition care plan, implementing the plan and additional considerations regarding PN preparation and readmissions. Safety concerns with risk-prone processes are identified and recommended best practices are proposed for improving processes at each step of the transition. Pediatric considerations are included in the evaluation of the various steps in the transition of care. This paper was approved by the American Society for Parenteral and Enteral Nutrition (ASPEN) Board of Directors.

Long-Term Outcomes With Teduglutide From a Single Center.

BACKGROUND: The aim of this study was to quantify the long-term clinical outcomes for individuals receiving teduglutide for short-bowel syndrome (SBS). METHODS: A single-center, retrospective study was performed for individuals commencing use of teduglutide between March 2013 and May 2019. RESULTS: Eighteen patients were included in the final analysis, among which the median duration of teduglutide administration was 3.2 (range, 0.6-6.2) years. Twelve of 16 (75%) patients at 12 months, 10 of 13 (76.9%) at 24 months, 7 of 10 (70%) at 36 months, and 3 of 3 (100%) at 60 months had a response to teduglutide therapy, defined as a >20% reduction in parenteral support (PS) requirement. Among responders at 12, 24, and 36 months, the presence of a colon-in-continuity, an ileocecal valve, a response at 3 months, the length of small bowel, nor the baseline volume affected response to therapy (P > .05 for all comparisons). Five (28%) patients were able to achieve freedom from PS, among which all had a history of Crohn's disease with loss of the ileocecal valve and among which 3 had a colon-in-continuity. Four of the 5 patients discontinued PS by 6 months of teduglutide therapy. CONCLUSIONS: In a real-world experience, teduglutide therapy results in rapid and sustained reductions in PS. Larger postmarketing studies will be required to reliably predict response to treatment and the factors associated with enteral autonomy.

Central venous catheters: incidence and predictive factors of venous thrombosis.

AIMS: Central venous catheter access in an acute setting can be a challenge given underlying disease and risk for venous thrombosis. Peripherally inserted central venous catheters (PICCs) are commonly placed but limit sites for fistula creation in patients with chronic renal failure (CKD). The aim of this study is to determine the incidence of venous thrombosis from small bore internal jugular (SBIJ) and PICC line placement. This investigation identifies populations of patients who may not be ideal candidates for a PICC and highlights the importance of peripheral vein preservation in patients with renal failure. MATERIALS AND METHODS: A venous Doppler ultrasound was performed at the time of SBIJ insertion and removal to evaluate for thrombosis in the internal jugular vein. Data was collected pre- and post-intervention to ascertain if increased vein preservation knowledge amongst the healthcare team led to less use of PICCs. Demographic factors were collected in the SBIJ and PICC groups and risk factor analysis was completed. RESULTS: 1,122 subjects had PICC placement and 23 had SBIJ placement. The incidence of thrombosis in the PICC group was 10%. One patient with an SBIJ had evidence of central vein thrombosis when the catheter was removed. Univariate and multivariate analysis demonstrated a history of transplant, and the indication of total parenteral nutrition was associated with thrombosis (p<0.001). The decrease in PICCs placed in patients with CKD 6 months before and after intervention was significant (p<0.05). CONCLUSIONS: There are subsets of patients ith high risk for thrombosis who may not be ideal candidates for a PICC.

A randomized, controlled trial evaluating postinsertion neck ultrasound in peripherally inserted central catheter procedures.

OBJECTIVE: Insertion of peripherally inserted central catheters (PICCs) at the bedside may result in tip malposition. This study was designed to evaluate whether the addition of ultrasound (US) inspection of the ipsilateral neck provides immediate recognition of PICCs in aberrant position facilitating catheter reposition before completion of the procedure. DESIGN: Randomized, controlled trial. SETTING: University-affiliated hospital. PATIENTS: Totally, 300 patients ordered for PICC placement. INTERVENTIONS: Patients were randomized to either postinsertion US inspection of the ipsilateral neck (intervention, n = 151) or to usual practice (control, n = 149). In the intervention group, catheters detected by US to be traveling within the ipsilateral internal jugular vein (IJ), were further adjusted before procedural completion. All procedures included US localization of the peripheral vein and postprocedural chest radiograph to assess catheter tip position. The primary end point was defined as the rate of PICC tip malposition in the ipsilateral IJ as detected by postprocedure chest radiograph. The secondary end point was procedure duration. MEASUREMENTS AND MAIN RESULTS: In the control arm, 140 of 149 PICC placement attempts (94%) were completed, including 11 procedures with catheter tips terminating in the ipsilateral IJ (7.9%). In the intervention arm, 142 of 151 attempts (94.7%, p = 0.98) were completed; one procedure resulted in a catheter tip in the ipsilateral IJ (0.7%, p = 0.007). Eleven intervention procedures included successful PICC repositioning during the initial procedure based on US detection of malposition. The median duration of the procedure in the control group was 8 minutes (6-10.5 minutes) and increased to 9.0 minutes (7-11 minutes) in the intervention group. CONCLUSIONS: Bedside PICC placement morbidity can be reduced via US inspection of the ipsilateral neck for PICC tip malposition in the IJ. This modality can guide catheters to be successfully repositioned during the initial procedure.

Improving the process of informed consent in the critically ill.

CONTEXT: Invasive procedures are often performed emergently in the intensive care unit (ICU), and patients or their proxies may not be available to provide informed consent. Little is known about the effectiveness of intensivists in obtaining informed consent. OBJECTIVES: To describe the nature of informed consent in the ICU and to determine if simple interventions could enhance the process. DESIGN, SETTING, AND PATIENTS: Prospective study of 2 cohorts of consecutively admitted patients (N = 270) in a 16-bed ICU at a university hospital. All patients admitted to the ICU during the baseline period from November 1, 2001, to December 31, 2001, and during the intervention period from March 1, 2002, to April 30, 2002, were included. INTERVENTION: A hospital-approved universal consent form for 8 commonly performed procedures (arterial catheter, central venous catheter, pulmonary artery catheter, or peripherally inserted central catheter placement; lumbar puncture; thoracentesis; paracentesis; and intubation/mechanical ventilation) was administered to patients or proxies. Handouts describing each procedure were available in the ICU waiting area. Physicians and nurses were introduced to the universal consent form during orientation to the ICU. MAIN OUTCOME MEASURES: Incidence of informed consent for invasive procedures at baseline and after intervention; whether the patient or proxy provided informed consent; and understanding by the consenter of the procedure as determined by the responses on a questionnaire. RESULTS: Fifty-three percent of procedures (155/292) were performed after consent had been obtained during the baseline period compared with 90% (308/340) during the intervention period (absolute difference, 37.4%; P<.001). During baseline, the majority (71.6%; 111/155) of consents were provided by proxies. This was also the case during the intervention period in which 65.6% (202/308) of consents were provided by proxies (absolute difference, 6.0%; P =.23). Comprehension by consenters of indications for and risks of the procedures was high and not different between the 2 periods (P =.75). CONCLUSIONS: Invasive procedures are frequent in the ICU and consent for them is often obtained by proxy. Providing a universal consent form to patients, proxies, and health care clinicians significantly increased the frequency with which consent was obtained without compromising comprehension of the process by the consenter.
