Diarrhoea risk factors in enterally tube fed critically ill patients: a retrospective audit

Reducing diarrhoea in an adult surgical intensive care unit: A quality improvement study

BACKGROUND

Although diarrhoea is a real source of morbidity for critically ill patients, this issue has been little studied, making it difficult to understand its mechanisms and management.

AIMS

We conducted a quality improvement study in an adult surgical intensive care unit before/after the implementation of a specific protocol to firstly improve diarrhoea management for patient benefit and secondly to understand the impact on caregivers.

STUDY DESIGN

The first part of this before/after study consisted in assessing the proportion of patients receiving an anti-diarrheal treatment before (phase I)/after (phase II) the implementation of the protocol. The second part of the study was to survey the caregivers on this topic.

RESULTS

Sixty four adults were included (33 in phase I; 31 in phase II) with 280 diarrheal episodes (129 in phase I; 151 in phase II). The proportion of patients who received at least one anti-diarrheal treatment was similar between the two phases (79% (26/33) vs. 68% (21/31), p = .40). Diarrhoea incidence was also similar (9% (33 patients/368 admissions) vs. 11% (31 patients/275 admissions), p = .35). The delay to initiate at least one treatment was significantly shorter in phase II (2 days [1-7] vs. 0 day [0-2]; p < .001). The patients' rehabilitation was no longer impacted by the occurrence of a diarrheal episode in phase II (39% (13/33) vs. 0% (0/31), p < .001). Eighty team members completed the surveys in phase I and 70 in phase II. Caregivers perceived diarrhoea like a burden and its economic impact remained high.

CONCLUSIONS

The implementation of a protocol for the management of ICU diarrhoea did not increase the proportion of patients treated, but it did significantly improve the delay to initiate a treatment. The patients' rehabilitation was no longer affected by diarrhoea.

RELEVANCE TO CLINICAL PRACTICE

The use of specific anti-diarrhoea guidelines may help to reduce the burden of diarrhoea in an ICU.

Diarrhea Caused by the Displacement of Percutaneous Endoscopic Gastrostomy Tube Tip Into the Duodenum: A Rare Case

Percutaneous endoscopic gastrostomy (PEG) is a widely used procedure for patients with dysphagia and inadequate oral intake. Although PEG offers numerous benefits, complications can occur. Here, we present an unusual case of a 68-year-old woman who developed persistent diarrhea following a routine PEG tube exchange. Despite treatment attempts, her symptoms persisted, prompting further investigation. Abdominal computed tomography (CT) revealed the unexpected displacement of the PEG tube tip into the duodenum. Repositioning of the tube tip into the stomach resolved the diarrhea, and the patient was discharged without recurrence. Diarrhea is a common gastrointestinal side effect in patients receiving enteral nutrition through a PEG tube, typically attributed to multiple factors. However, to our knowledge, this is the first reported case of diarrhea resulting from a PEG tube tip straying into the duodenum. The patient did not undergo any changes in enteral preparation or receive medications known to cause diarrhea. The identification of the tube misplacement was incidental during the CT scan, underscoring the importance of imaging studies in refractory cases. While previous reports indicate no significant difference in diarrhea occurrence between duodenal and gastric feeding, our findings suggest that the presence of the PEG tube tip in the duodenum may contribute to diarrhea in some patients. This case highlights the potential role of CT imaging in diagnosing the cause of persistent diarrhea in PEG-fed individuals. Further accumulation of cases is necessary to establish the significance of duodenal tube placement as a cause of diarrhea during PEG procedures. In conclusion, this case report emphasizes the importance of considering tube misplacement as a potential cause of refractory diarrhea in patients receiving enteral nutrition through a PEG tube. The use of abdominal CT imaging can be valuable in identifying such misplacements and guiding appropriate interventions. Further research is needed to validate these findings and explore the clinical implications for the management of PEG-related diarrhea.

Investigating the effect of oral synbiotic on enteral feeding tolerance in critically ill patients: A double-blinded controlled clinical trial of gut microbiota

BACKGROUND

Probiotics are beneficial live microorganisms that can modify the gut microbiota. It is assumed that they help improve enteral feeding intolerance (EFI) and nosocomial infections in critically ill patients. The present clinical trial aimed to investigate the efficacy of synbiotics in improving EFI and oropharyngeal aspiration in patients admitted to the intensive care unit (ICU).

METHODS

This randomized clinical trial was conducted on 105 critically ill patients admitted to the ICU of a tertiary referral hospital affiliated with a medical university. The patients were randomly assigned to either a synbiotic or control group and underwent 7 days of investigation. The primary end point was reduced gastric residual volume, which is suggestive of an improvement in EFI. The secondary end point included requirement for prokinetics, frequency of aspiration, duration of mechanical ventilation, length of ICU stay, and level of consciousness.

RESULTS

The present clinical trial showed that synbiotic intervention has resulted in a significantly diminished requirement for prokinetics (P = 0.019), fewer oropharyngeal aspirations (P = 0.01), improved volume of bolus administration, and decreased gastric residual volume during the 7-day follow-up period. The patients who received synbiotic had an improved level of consciousness (P = 0.01).

CONCLUSION

This clinical trial showed that the prescription of synbiotic from the initial days of enteral feeding has resulted in a significantly diminished requirement for prokinetics, less oropharyngeal aspiration, decreased gastric residual volume, improved volume of bolus administration, and hence, better tolerance of enteral feeding.

Effects of dietary fibre on enteral feeding intolerance and clinical outcomes in critically ill patients: A meta-analysis

BACKGROUND

Although some studies have explored the relationships between dietary fibre and enteral feeding intolerance in critically ill patients, the results are equivocal.

OBJECTIVE

This study aimed to explore the effects of dietary fibre on enteral feeding intolerance and clinical outcomes in critically ill patients.

METHODS

We searched five databases from inception to July 12, 2021. Data were expressed as mean difference or odds ratio with 95% confidence interval.

RESULTS

Thirteen studies enrolled 709 critically ill patients included in the study. The results showed the dietary fibre group had a significantly decreased risk of diarrhea (OR: 0.46, 95% CI: 0.30,0.69, P < 0.001), regurgitation (OR: 0.28, 95%CI: 0.13, 0.60, P < 0.05), vomiting (OR: 0.40, 95%CI: 0.17, 0.92, P < 0.05), constipation (OR: 0.21, 95%CI: 0.09, 0.47, P < 0.001) and mortality (OR:0.34; 95%CI:-0.13, 0.91; P < 0.05) compared with the fibre free group. Besides, there was a significant decrease on time to reach full enteral nutrition (MD:-2.08; 95%CI:-4.05, -0.12; P < 0.05), the duration of the intensive care unit stay (MD:-4.62; 95%CI:-6.60, -2.64; P < 0.001) and hospital stay (MD:-6.42; 95%CI:-9.49, -3.36; P < 0.001) in the dietary fibre group.

CONCLUSIONS

Dietary fibre supplementation may significantly reduce the risk of enteral feeding intolerance and improve the clinical outcomes.

Enteral Nutrition and Hydration in Patients with Acute Stroke: Efficacy of an Automatic Pump System for Water Administration and Flushes-A Pilot Study

BACKGROUND

Enteral nutrition is often prescribed in acute stroke to meet energy and fluid needs in patients with dysphagia. Tubes clogging represent a common complication of enteral formula delivery, requiring substitution and influencing nutrition administration. Frequent water flushes are recommended as one of the most effective procedures to prevent tube occlusion, but it might be time demanding and not consistently performed by the healthcare staff. This study aimed to assess the efficacy of an automatic flush pump, compared to a manual flush system, to prevent tubes' occlusions in acute-stroke patients, as this might affect nutrition and hydration.

METHODS

Gastrointestinal symptoms, nutrition and hydration biomarkers were also monitored to determine the different devices' safety. Sixty-two patients were included in the study and allocated to the "manual" or "automatic" flushes device.

RESULTS

The mean duration of data collection was 7 ± 2 days. Tube occlusions occurred in 22.6% of the patients in the "manual" group, whereas only one tube clogging was reported in the "automatic" group (p = 0.023). No significant differences between groups were reported for constipation and diarrhea frequency nor nutrition and hydration status. When the nurses were asked to simulate manual flush administration at the same frequency of the automatic device, they were able to meet the recommendations only 10% of the time.

CONCLUSION

This preliminary study suggests the efficacy of automatic flush systems to prevent enteral tube clogging, without affecting health status compared to standard manual flush systems.

Gastrointestinal Dysmotility in Critically Ill Patients: Bridging the Gap Between Evidence and Common Misconceptions

Disruption of normal gastrointestinal (GI) function in critical illness is linked to increased morbidity and mortality, and GI dysmotility is frequently observed in patients who are critically ill. Despite its high prevalence, the diagnosis and management of GI motility problems in the intensive care unit remain very challenging, given that critically ill patients often cannot verbalize symptoms and the general lack of understanding of underlying pathophysiology. Common clinical presentations of GI dysmotility issues among critically ill patients include: (1) high gastric residual volumes, acid reflux, and vomiting, (2) abdominal distention, and (3) diarrhea. In this review, we discuss the differential diagnosis for intensive care unit patients with symptoms and signs concerning GI motility issues. There are many myths and longstanding misconceptions about the diagnosis and management of GI dysmotility in critical illness. Here, we uncover these myths and discuss relevant evidence in each subject area, with the goal of re-conceptualizing GI motility disorders in critical care and providing evidence-based recommendations for clinical care.

Early Enteral Nutrition with High-Protein Whey Peptide Digestive Nutrients May Improve Prognosis in Subarachnoid Hemorrhage Patients

Background and Objectives: Nutritional management in patients with subarachnoid hemorrhage (SAH) during the acute phase is important; however, there is no proper evidence or recommendations on the appropriate nutrients for early enteral nutrition. This study compared the influence the two different tube-feeding liquid diets for early enteral nutrition might have on the prognosis of patients with SAH. Materials and Methods: In a seven-year period, this single-center retrospective study included 245 patients with aneurysmal SAH who underwent craniotomy and aneurysm neck clipping and received enteral nutrition. The patients were divided into two groups according to the nutrient received: (1) high-protein whey peptide oligomeric formula diet (oligomeric group, 109 patients); and (2) high eicosapentaenoic acid-containing polymeric formula diet (polymeric group, 136 patients). The modified Rankin Scale (mRS) score at discharge was evaluated as the primary outcome. The presence or absence of diarrhea (watery stool and mushy stool) during the period from initiation of enteral nutrition to discharge from the stroke unit was also evaluated. Results: There were no significant differences in patient characteristics between groups. The time until initiation of enteral feeding in the oligomeric and polymeric groups was 2.8 ± 2.3 and 2.9 ± 2.2 days, respectively. The proportion of patients with mRS scores of 0–1 was significantly higher in the oligomeric group (25.7%) than in the polymeric group (14.7%) (p = 0.036), while the incidence of watery stool was significantly lower in the oligomeric group (15.8% to 34.3% in the polymeric group) (p = 0.003). Multivariate analyses confirmed that the oligomeric diet and the presence or absence of diarrhea significantly affected the mRS scores. Conclusions: The adoption of early enteral nutrition with high-protein whey peptide digestive nutrients might be associated with superior mRS scores at discharge and decreased diarrhea in patients with SA, indicating that the choice of nutrients might affect the outcome and prognosis.

A Structured Skin Care Protocol for Preventing and Treating Incontinence-associated Dermatitis in Critically Ill Patients

OBJECTIVE

To examine the effectiveness of a structured skin care protocol for preventing and treating incontinence-associated dermatitis (IAD) in critically ill patients.

METHODS

Participants were drawn from the ICUs of three teaching hospitals between January 2016 and December 2017. Patients were eligible if they were ≥18 years old, had idiopathic fecal incontinence, had diarrhea but were unable to sense it, and were expected to stay in the ICU for at least 72 hours after developing incontinence. A total of 143 patients were enrolled: 79 in the experimental group and 64 in the control group. In the first phase of the study, routine skin care measures were used; in the second phase, three ICU caregivers were trained to provide a structured skin care protocol. Trained research team members conducted the data collection and analysis. The TREND (Transparent Reporting of Evaluations with Nonrandomized Designs) Statement Checklist was followed in reporting the study results.

RESULTS

Application of the structured skin care protocol reduced the incidence of IAD from 35.9% in the control phase to 17.7% in the intervention phase (χ2 = 6.117, P < .05) and also decreased the severity of IAD (z = -2.023, P < .05). Further, IAD developed later (z = -2.116, P < .05) in the intervention group than in the control group. In addition, the nursing times to prevent or manage IAD did not differ significantly between the groups (t = -0.258, P > .05; t = -1.190, P > .05).

CONCLUSIONS

Use of the developed structured skin care protocol for IAD in critically ill patients lowered the incidence and severity of IAD and delayed IAD development.

Diarrhea during critical illness: a multicenter cohort study

PURPOSE

To study the incidence, predictors, and outcomes of diarrhea during the stay in the intensive care unit (ICU).

METHODS

Prospective cohort of consecutive adults in the ICU for > 24 h during a 10-week period across 12 intensive care units (ICUs) internationally. The explored outcomes were: (1) incidence of diarrhea, (2) Clostridioides difficile-associated diarrhea (CDAD); (3) ICU and hospital length of stay (LOS) and mortality in patients with diarrhea. We fit generalized linear models to evaluate the predictors, management, morbidity and mortality associated with diarrhea.

RESULTS

Among 1109 patients aged 61.4 (17.5) [mean (standard deviation)] years, 981(88.5%) were medical and 645 (58.2%) were mechanically ventilated. The incidence was 73.8% (818 patients, 73.8%, 95% confidence interval [CI] 71.1-76.6) using the definition of the World Health Organisation (WHO). Incidence varied across definitions (Bristol 53.5%, 95% CI 50.4-56.7; Bliss 37.7%, 95% CI 34.9-40.4). Of 99 patients with diarrhea undergoing CDAD testing, 23 tested positive (2.2% incidence, 95% CI 1.5-3.4). Independent predictors included enteral nutrition (RR 1.23, 95% CI 1.16-1.31, p < 0.001), antibiotic days (RR 1.02, 95% CI 1.02-1.03, p < 0.001), and suppositories (RR 1.14 95% CI 1.06-1.22, p < 0.001). Opiates decreased diarrhea risk (RR 0.76, 95% CI 0.68-0.86, p < 0.001). Diarrhea prompted management modifications (altered enteral nutrition or medications: RR 10.25, 95% CI 5.14-20.45, p < 0.001) or other consequences (fecal management device or CDAD testing: RR 6.16, 95% CI 3.4-11.17, p < 0.001). Diarrhea was associated with a longer time to discharge for ICU or hospital stay, but was not associated with hospital mortality.

CONCLUSION

Diarrhea is common, has several predictors, and prompts changes in patient care, is associated with longer time to discharge but not mortality.

Intragastric prepyloric enteral nutrition, bolus vs continuous in the adult patient: A systematic review and meta-analysis

Bolus and continuous nutrition are commonly used enteral nutrition (EN) administration methodologies. Currently, there is insufficient evidence to establish which is the most effective method for reducing gastrointestinal complications in adult patients. The aim of this review is to evaluate the impact of bolus/intermittent EN compared with continuous EN for the following outcomes: diarrhea, constipation, emesis/vomiting, gastric residual volume, aspiration, and glycemic control in adult patients receiving intragastric prepyloric EN in the hospital setting. Bibliographical research was performed on the following databases: PubMed, Embase, CINAHL, and the Cochrane Central Register of Controlled Trials. The review included all randomized and nonrandomized controlled trials of patients aged ≥18 years with preserved gastrointestinal function. Meta-analysis was performed by Review Manager V.5.3. Seven studies including 551 patients were included in the meta-analysis. Five of these studies reported that the diarrhea rate was higher in the bolus feeding group (risk ratio [RR] = 2.50; 95% CI, 1.17-5.34; P = 0.02), and another five of these studies indicated that the aspiration rate was higher in the continuous feeding group (RR = 0.55; 95% CI, 0.35-0.87; P = 0.01). There were no significant differences for the other outcomes. In conclusion, intermittent EN appears to reduce the incidence of aspiration in the hospital setting; however, it may increase the risk of diarrhea. For future research, we hypothesize the joint use of continuous nutrition until the patient reaches tolerance and then passing to bolus nutrition, thus reducing the incidence of aspiration and enabling a physiological nutrition intake.

Diarrhea in tube-fed hospitalized patients: Feeding formula is not the most common cause

BACKGROUND AND AIM

Clostridium difficile-associated diarrhea (CDAD) and enteral nutrition (EN)-associated diarrhea are the most common recognized etiologies of nosocomial diarrhea. However, in clinical practice, the data regarding how each etiology contributes to the diarrheal episodes are limited. We identify the causes and factors associated with post-feeding diarrhea.

METHODS

Using the data of patients enrolled in "Effect of Psyllium Fiber Supplementation on Diarrhea Incidence in Enteral Tube-Fed Patients: A Prospective, Randomized, and Controlled Trial", the randomized controlled trial showed no difference in diarrheal incidences between fiber-added and fiber-free formulas. Hence, we analyzed the data of all enrolled patients. The causes of diarrhea were classified according to pre-specified definitions. The factors associated with diarrhea were analyzed using logistic regression.

RESULTS

Diarrhea was found in 37.3% (n = 31/83). The most common cause was medication associated (61.3%). CDAD and EN-associated diarrhea were found in only 9.7% and 6.5%, respectively. Patients with baseline albumin <3 g/dL and underlying cerebrovascular disease were more likely to develop diarrhea (adjusted odds ratio 5.70, 95% confidence interval 1.79-20.51, and adjusted odds ratio 10.83, 95% confidence interval 2.96-48.57, respectively). Compared with those without diarrhea, the length of hospital stay in CDAD patients was significantly longer (+23.1 days, P = 0.02), a trend of longer hospital stay in patients with diarrhea from other causes was observed (+3.2 days, P = 0.096).

CONCLUSIONS

Our study found that the most common cause of post-feeding diarrhea is medication associated. Review and cessation of possible drugs should be undertaken before EN modification. CDAD accounts for <10% of diarrhea causes, but it impacts the clinical outcome and should be identified and treated properly.

Incontinence-associated dermatitis: who is affected?

OBJECTIVE

Intensive care unit (ICU) patients possess multiple risk factors for developing loss of skin integrity, particularly incontinence-associated dermatitis (IAD). IAD is an inflammatory skin condition resulting from repeated and prolonged contact with urine, faeces or both. This study aimed to measure the incidence and clinical characteristics of adult ICU patients with IAD.

METHOD

This was a prospective observational study conducted over three months in an adult ICU. Included patients were ≥18 years who experienced faecal incontinence during their intensive care admission. Patients were excluded if they had an ileostomy or colostomy, had IAD on admission, or were continent of urine and faeces. Skin inspections were performed every second day on all recruited patients by trained research nurses. Other data were collected from patient medical records.

RESULTS

A total of 37 patients took part in the study. Incidence of IAD was 35.1%; 13 patients who had incontinence developed IAD. The mean time to onset of IAD was 3.69 days, median 3 days (SD: 1.8, range: 2-8 days). Of the 13 patients who developed IAD, 12 (92.3%) patients were initially assessed as having category 1 IAD and one (7.7%) patient was initially assessed with category 2 IAD. Of the patients with category 1 IAD, one patient (7.7%) progressed to category 2 IAD severity.

CONCLUSION

A larger sample is recommended to fully explore ICU patient characteristics and IAD development. The incidence of IAD in ICU patients was high at 35%, indicating this condition requires due consideration in ICU patients.

Effects of curd on diarrhea treatment in patients with head trauma receiving enteral feeding in intensive care units

BACKGROUND: Diarrhea in patients on enteral feeding is a common complication with serious clinical outcomes. In Eastern and Southern Mediterranean regions, using curd as a food for the treatment of diarrhea is a common practice. OBJECTIVE: This study aimed to investigate whether curd could reduce the duration or severity of diarrhea in critically ill tube-fed patients with head trauma. METHODS: A total of 42 patients on enteral feeding who had diarrhea after starting enteral feeding, admitted to the intensive care unit, were randomly assigned to either to receiving curd and standard enteral formula or standard enteral formula only groups. The intervention period for each patient was three days. The primary outcome was the duration of diarrhea, while the secondary outcomes were the frequency and weight of stool per day in each patient. RESULTS: This study showed a significantly higher stool weight in patients receiving enteral curd (588.76±266.88 vs 390.60±171.82 gr/day). There was no significant difference between the groups in duration of diarrhea (9 v 8 days) and episodes of diarrhea per day (2.20±1.00 vs 2.00±0.70) in intervention and control groups. incidence of liquid or loose stools on days 1–4 of the intervention (P1 = 0.43, P2 = 0.16, P3 = 0.45, P4 = 0.62). Feeding with curd did not change the APACHE score in intervention and control groups. This study showed no significant difference in 28 days of mortality in intervention and control groups. CONCLUSION: The findings showed that supplementary enteral feeding with curd did not improve diarrhea, the severity of the disease, or 28 days mortality in critically ill patients with diarrhea receiving enteral nutrition.

Does the presence of bacterial urinary infection contribute to the development of incontinence-associated dermatitis? A scoping review

OBJECTIVE

Incontinence-associated dermatitis (IAD) is an inflammatory skin condition caused by the repeated exposure to urine and faeces. It is not common for urinary incontinence only to cause IAD, however patients with urinary tract infections (UTIs) are also at increased risk for IAD. This scoping review aimed to provide a summary of the relationship between bacterial urinary infections and IAD.

METHODS

We conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. PubMed, CINAHL, Medline, and Web of Science were searched for relevant articles from January 2007 through February 2020.

RESULTS

Based on eligibility criteria, 13 research studies and review articles were included. Despite the acknowledged role of bacterial infections can play in IAD and the importance of eradicating infections for the prevention of skin breakdown, there have been limited studies that have investigated how uropathogenic bacteria, in combination with urine, lead to skin damage and IAD. The use of urinary catheters also predisposes to UTIs; however, prevalence/incidence rates of IAD in these patients are not clear, as they were considered as continent of urine in the included studies.

CONCLUSION

Further research is needed to elucidate the mechanisms of how bacteria, in combination with urine, lead to IAD.

Factors associated with enteral nutrition and the incidence of gastrointestinal disorders in a cohort of critically ill adults

Introduction

Introduction: adults in intensive care commonly receive enteral nutrition (EN). Data describing the conditions associated with EN in critically ill patients are limited. Objective: to describe the incidence of gastrointestinal disorders and to identify conditions associated with the use of EN. Methods: a prospective cohort, single-center study of critically ill adults. The patients were followed daily for the first 10 days of hospitalization in the intensive care unit (ICU) or until ICU discharge or death. Clinical, nutritional variables and gastrointestinal disorders were compared between patients who did and did not receive EN. Univariate and multivariate regression identified the conditions associated with EN with the proposed variables. Results: of the 157 included adults, 62 % received EN. The EN group had higher APACHE II (23.6 ± 7.6 vs. 15 ± 7.2, p < 0.001) and SOFA scores on the day of ICU admission [7 (5-10.5) vs. 4 (2-6); p < 0.001], and higher ICU mortality (32 % vs. 10 %, p = 0.002). Diarrhea and need for gastric decompression were more frequent in the EN group (39.7 % vs. 11.7 %, p < 0.001 and 34 % vs. 13.3 %, p = 0.004, respectively). The multivariate analysis showed that neurological deficit (OR: 16.7 [95 % CI: 5.9-46.9]; p < 0.001), previous enteral tube feeding (OR: 45.1 [95 % CI: 5.3-380]; p < 0.001), and SOFA score on the day of ICU admission (OR: 1.2 [95 % CI: 1.01-1.3]; p = 0.03) were associated with EN. Conclusions: conditions related to the severity of critically ill patients, such as higher SOFA scores, greater neurological deficit, and prior enteral tube feeding, were more commonly associated with EN. Diarrhea and need for gastric decompression were more frequent in patients who received EN.

Efficacy of a comprehensive strategy to reduce moisture-associated skin damage in an intensive care unit: A quasi-experimental study

OBJECTIVES

Assess the impact of a bundle of interventions to reduce the incidence of moisture-associated skin damage in an intensive care unit.

METHODS

Quasi-experimental study with pre-post comparison carried out in a general intensive care unit. The intervention consisted of an online training on skin lesions and implementation of a skin care program. In the pre-post intervention period, the skin of the pelvic area was assessed daily until the appearance of a moisture-related lesion or intensive care unit discharge. Demographic and clinical variables, type of moisture lesion and severity were collected. To assess the impact of the intervention the odds ratio (OR) adjusted for the confounding variables was used.

RESULTS

Trained nurses accounted for 87.7%. In each phase 145 patients were studied. The incidence of moisture-associated skin damage in the pre-phase was of 29% and 14.5% in the post phase. The OR adjusted for the confounding variables (ICU length of stay, obesity, faecal incontinence and non-communicative patients) was 0.44 (95%CI:0.23-0.82). The reduction of incontinence-associated dermatitis presented an OR of 0.81 (95%CI:0.30-2.16) and intertriginous dermatitis of 0.39 (95%CI:0.17-0.85).

CONCLUSIONS

Online training for nurses and the introduction of structured skin care reduced by half the moisture-associated skin damage, especially intertriginous dermatitis.

Moisture associated skin damage (MASD) in intensive care patients: A Norwegian point-prevalence study

BACKGROUND

Critically ill patients are at risk of developing moisture associated skin damage and pressure ulcers. These conditions may co-exist and be difficult to distinguish, but a simultaneous investigation may provide a true prevalence.

OBJECTIVES

To investigate the prevalence of moisture associated skin damage and associated factors among Norwegian intensive care patients.

METHODS

A multi-centre one-day point-prevalence study.

RESULTS

Totally, 112 patients participated in the study. Overall, 15 patients (13%, 15/112) had some type of moisture associated skin damage of which six cases (5%, 6/112) were related to faeces and/or urine (incontinence associated dermatitis). Skin breakdown occurred primarily in the pelvic area. Overall, 87% (97/112) had an indwelling urinary catheter. Stools were reported in 42% (47/112) of the patients on the study day, mostly liquid or semi-liquid. Overall, 11% (12/112) had a faecal management system. Only a few care plans for moisture associated skin damage prevention and care existed.

CONCLUSION

Patients in this study were vulnerable to skin breakdown in the pelvic area. Nevertheless, a low prevalence of skin breakdown existed. This may relate to intensive care nurses' qualifications, the 1:1 nurse-patient staffing, the high prevalence of urinary catheters and few patients having stools.

Exploring Incontinence-Associated Dermatitis in a Single Center Intensive Care Unit: A Longitudinal Point Prevalence Survey

PURPOSE

The purpose of this study was to provide longitudinal prevalence rates of incontinence-associated dermatitis (IAD) in patients in an intensive care unit (ICU) and to identify patient characteristics associated with IAD development.

DESIGN

Prospective observational.

SUBJECTS AND SETTING

The sample comprised 351 patients aged 18 years and older in a major metropolitan public hospital ICU in Queensland, Australia.

METHODS

All consenting, eligible participants at risk of developing IAD underwent weekly skin inspections to determine the presence of IAD. Data were collected weekly for 52 consecutive weeks. Descriptive statistics described the study sample and logistic regression analysis was used to identify patient characteristics associated with development of IAD.

RESULTS

The weekly IAD prevalence ranged between 0% and 70%, with IAD developing in 17% (n = 59/351) of ICU patients. The odds of IAD developing increased statistically significantly with increasing age (odds ratio [OR]: 1.029, 95% confidence interval [CI]: 1.005-1.054, P = .016), time in the ICU (OR = 1.104; 95% CI: 1.063-1.147, P < .001), and Bristol Stool chart score (OR = 4.363, 95% CI: 2.091-9.106, P < .001). Patients with respiratory (OR = 3.657, 95% CI: 1.399-9.563, P = .008) and sepsis (OR = 3.230, 95% CI: 1.281-8.146, P = .013) diagnoses had increased odds of developing IAD.

CONCLUSIONS

These data show the high variability of IAD prevalence over a 1-year period. Characteristics associated with the development of IAD in patients in the ICU included older age, longer lengths of ICU stay, incontinent of liquid feces, and having respiratory or sepsis diagnoses.

Risk Factors and Predictive Model of Diarrhea Among Patients with Severe Stroke

OBJECTIVE

To investigate the risk factors and predictive model of diarrhea among patients with severe stroke.

METHODS

The study analyzed the retrospective clinical data of patients with new-onset stroke who had been admitted to the intensive care unit at the Department of Neurology of X Hospital, between September 2017 and April 2018. All data were analyzed with a binary logistic regression, and a logistic regression equation was used to build a predictive model of diarrhea among patients with severe stroke.

RESULTS

A total of 153 patients with severe stroke were included in this study, including 45 patients (29.41%) with diarrhea. The binary logistic multivariate analysis showed that the National Institutes of Health Stroke Scale score at admission (odds ratio [OR], 1.123; 95% confidence interval [CI], 1.016-1.242), the Glasgow Coma Scale score at admission (OR, 1.563; 95% CI, 1.048-2.330), antibiotic use (OR, 2.168; 95% CI, 1.041-4.514), gavage feeding time (OR, 1.260; 95% CI, 1.098-1.445), and hospital stay before the occurrence of diarrhea (OR, 0.652; 95% CI, 0.552-0.770). The receiver operating characteristic curve was 0.862 (95% CI, 0.799-0.925), the specificity was 0.778, and the sensitivity was 0.843.

CONCLUSIONS

The National Institutes of Health Stroke Scale score at admission, the Glasgow Coma Scale score at admission, antibiotic use, gavage feeding time, and hospital stay before the occurrence of diarrhea independently predict diarrhea among patients with severe stroke. This model can be used to predict the risk of diarrhea among patients with severe stroke.

Tube Feeding in Individuals with Advanced Dementia: A Review of Its Burdens and Perceived Benefits

Background

Dementia remains a growing concern for societies globally, particularly as people now live longer. About 90% of individuals with advanced dementia suffer from eating problems that lead to general health decline and ultimately impacts upon the physical, psychological, and economic wellbeing of the individuals, caregivers, and the wider society.

Objective

To evaluate the burdens and perceived benefits of tube feeding in individuals with advanced dementia.

Design

Narrative review.

Methods

Computerized databases, including PubMed, Embase, Medline, CINAHL, PsycInfo, and Google Scholar were searched from 2000 to 2019 to identify research papers, originally written in or translated into English language, which investigated oral versus tube feeding outcome in individuals with advanced dementia.

Results

Over 400 articles were retrieved. After quality assessment and careful review of the identified articles, only those that met the inclusion criteria were included for review.

Conclusion

Tube feeding neither stops dementia disease progression nor prevents imminent death. Each decision for feeding tube placement in individuals with advanced dementia should be made on a case-by-case basis and involve a multidisciplinary team comprising experienced physicians, nurses, family surrogates, and the relevant allied health professionals. Careful considerations of the benefit-harm ratio should be discussed and checked with surrogate families if they would be consistent with the wishes of the demented person. Further research is required to establish whether tube feeding of individuals with advanced dementia provides more burdens than benefits or vice-versa and evaluate the impacts on quality of life and survival.

The independent risk factors of early diarrhoea in enteral nutrition for ICU patients

Objective

To investigate the prevalence of and factors associated with diarrhoea in the early stage of enteral nutrition in critically ill patients in intensive care units (ICUs).

Methods

This prospective, multicentre, observational study enrolled consecutive patients who were newly admitted to ICUs and received enteral nutrition treatment. Events were observed continuously for 7 days or until patients were transferred out of the ICU after enteral nutrition. Demographic and clinical data, enteral nutrition data, diarrhoea-related data and outcomes were recorded. A multivariate logistic regression analysis was used to analyse the risk factors for diarrhoea.

Results

The study included 533 patients, of whom 164 (30.8%) developed diarrhoea. Diarrhoea was most commonly observed on the first to third days after starting enteral nutrition treatment. The median (interquartile range) duration of diarrhoea was 2 (1–3) days. The administration of gastrointestinal prokinetic agents, the increase in acute physiological and chronic health scores and the pyloric posterior feeding method were independent risk factors for diarrhoea.

Conclusion

The increased severity of illness, the administration of gastrointestinal prokinetic agents and the pyloric posterior feeding method were independent risk factors for diarrhoea in critically ill ICU patients undergoing enteral nutrition treatment.

Diarrhoea: interventions, consequences and epidemiology in the intensive care unit (DICE-ICU): a protocol for a prospective multicentre cohort study

INTRODUCTION

Diarrhoea is a frequent concern in the intensive care unit (ICU) and is associated with prolonged mechanical ventilation, increased length of ICU stay, skin breakdown and renal dysfunction. However, its prevalence, aetiology and prognosis in the critically ill have been poorly studied. The primary objectives of this study are to determine the incidence, risk factors and consequences of diarrhoea in critically ill adults. The secondary objectives are to estimate the incidence of Clostridium difficile-associated diarrhoea (CDAD) in ICU patients and to validate the Bristol Stool Chart and Bliss Stool Classification System characterising bowel movements in the ICU. Our primary outcome is the incidence of diarrhoea . Our secondary outcomes include: CDAD, ICU and hospital mortality and ICU and hospital length of stay.

METHODS AND ANALYSIS

This international prospective cohort study will enrol patients over 10 weeks in 12 ICUs in Canada, the USA, Poland and Saudi Arabia. We will include all patients 18 years of age and older who are admitted to the ICU for at least 24 hours and follow them daily until ICU discharge. Our primary outcome is the incidence of diarrhoea based on the WHO definition, during the ICU stay. Our secondary outcomes include: CDAD, ICU and hospital mortality and ICU and hospital length of stay. We will use logistic regression to identify factors associated with diarrhoea (as defined using WHO criteria) and the kappa statistic to measure agreement on diarrhoea rates between the WHO definition and the Bristol Stool Chart and Bliss Stool Classification System.

ETHICS AND DISSEMINATION

The protocol has been approved by the research ethics board of all participating centres. The diarrhoea interventions, consequences and epidemiology in the intensive care unit (DICE-ICU) study will generate evidence about diarrhoea and its frequency, predisposing factors and consequences, to inform critical care practice and future research.

LAY SUMMARY

Diarrhoea is a frequent clinical problem for hospitalised patients including those who are critically ill in the ICU. Diarrhoea can cause complications such as skin damage, dehydration and kidney problems. It is not clear how common diarrhoea is in the ICU, the factors that cause it or the best way for clinicians to assess it. The DICE-ICU study is an international prospective observational study to examine the frequency, risk factors and outcomes of diarrhoea during critical illness.

Constipation, diarrhea, and prophylactic laxative bowel regimens in the critically ill: A systematic review and meta-analysis

INTRODUCTION

Prophylactic laxative bowel regimens may prevent constipation in enterally-fed critically ill patients. However, their use may also increase diarrhea. We performed a systematic review to: 1. Explore the epidemiology of constipation and/or diarrhea in critically ill patients; and 2. Appraise trials evaluating prophylactic laxative bowel regimens.

METHODS

We searched MEDLINE, Embase, and CINAHL for publications that reported constipation or diarrhea in critically ill adult patients and/or prophylactic laxative bowel regimens.

RESULTS

The proportion of critically ill patients experiencing constipation was reported between 20% and 83% and the proportion experiencing diarrhea was reported between 3.3% and 78%. Six studies of prophylactic laxative bowel regimens were identified but only 3 randomised controlled trials were identified, and these were subjected to meta-analysis. Compared with placebo, a prophylactic laxative bowel regimen increased the risk of diarrhea (RR 1.58, 95% CI 1.22 to 2.04) but did not reduce the risk of constipation (RR 0.39, 95% CI 0.14 to 1.05), and did not affect the duration of mechanical ventilation, duration of ICU admission, or mortality.

CONCLUSIONS

Constipation and diarrhea occur frequently in the critically ill but data evaluating prophylactic laxative bowel regimens in such patients are sparse and do not support their use.

Determining the impact of a bowel management protocol on patients and clinicians' compliance in cardiac intensive care: A mixed-methods approach

BACKGROUND

Bowel management protocols standardise care and, potentially, improve the incidence of diarrhoea and constipation in intensive care. However, little research exists reporting compliance with such protocols in intensive care throughout patients' stay. Furthermore, there is a limited exploration of the barriers and enablers to bowel management protocols following their implementation, an important aspect of improving compliance.

AIM AND OBJECTIVE

To investigate the impact of a bowel management protocol on the incidence of constipation and diarrhoea, levels of compliance, and to explore the enablers and barriers associated with its use in intensive care.

METHODS

A mixed-methods study was conducted in cardiac intensive care using two phases: (a) a retrospective case review of patients' hospital notes, before and after the protocol implementation, establishing the levels of diarrhoea and constipation and levels of compliance; (b) focus groups involving users of the protocol, 6 months following its implementation, exploring the barriers and enablers in practice.

RESULTS AND FINDINGS

Fifty-one patients' notes were reviewed during phase one: 30 pre-implementation and 21 post-implementation. Following the protocol implementation, there was a tendency for a higher incidence of constipation and less severe cases of diarrhoea. Overall compliance with the protocol was low (2.3%). However, there was evidence of behavioural change following protocol implementation, including less variation in aperients given and a shorter, less varied time period between starting enteral feed and administering aperients. Several themes emerged from the focus groups: barriers and enablers to the protocol characteristics and dissemination; barriers to bowel assessment; nurse as a barrier; medical involvement and protocol outcomes.

CONCLUSIONS

The bowel management protocol implementation generated some positive outcomes to bowel care practices. However, compliance was low and until there is improvement, through overcoming the barriers identified, the impact of such protocols in practice will remain largely unknown.

Incidence of diarrhea and associated risk factors in patients with traumatic brain injury and enteral nutrition

To determine the occurrence of diarrhea and associated factors in critically ill patients with traumatic brain injury (TBI) in use of nutritional therapy. Prospective cohort study conducted in an Intensive Care Unit (ICU) of a General Hospital reference in trauma. We evaluated TBI patients who stayed less than 72 h in the ICU, who were using EN for at least 48 h. Definition of diarrhea it was considered three or more episodes of liquid stools or semi-liquid at 24 h. For analysis were evaluated demographic, epidemiological, clinical and nutritional data. Twenty-three patients were evaluated, being 86.9% male, median 33 years old (IQR = 25-52 years) and 16-day ICU stay (IQR = 10-26 days). Diarrhea occurred in 69.6% of the patients and they had a longer time in the ICU (p = 0.007). All patients who used combination prokinetic therapy (metoclopramide and erythromycin) and used antibiotics for more than 8 days had diarrhea (p = 0.057 and p = 0.007, respectively). The incidence of diarrhea was high in TBI patients with enteral nutrition and was associated with the use of antibiotics for more than one week.

Independent risk factors for the development of incontinence-associated dermatitis (category 2) in critically ill patients with fecal incontinence: A cross-sectional observational study in 48 ICU units

BACKGROUND

Critically ill patients suffering from fecal incontinence have a major risk of developing incontinence-associated dermatitis (IAD). The presence of moisture and digestive enzymes (lipase, protease) negatively influences skin barrier function. Additional risk factors will make some patients even more vulnerable than others. In order to provide (cost) effective prevention, this specific patient population should be identified timely.

OBJECTIVES

To identify independent risk factors for the development of IAD category 2 (skin loss) in critically ill patients with fecal incontinence.

DESIGN

A cross-sectional observational study.

SETTING AND PARTICIPANTS

The study was performed in 48 ICU wards from 27 Belgian hospitals. Patients of 18 years or older, with fecal incontinence at the moment of data collection, were eligible to participate. Patients with persistent skin redness due to incontinence (IAD category 1) were excluded.

METHODS

Potential risk factors were carefully determined based on literature and expert consultations. Data were collected over a period of eight months by trained researchers using patient records and observation of skin care practices. At the time a patient was included in the study, all relevant data from the past six days, or since admission at the ICU, were recorded. Simultaneously, direct skin observations were performed and high definition photographs were ratified by an expert IAD researcher. A multiple binary logistic regression model was composed to identify independent risk factors. Variables with P < .25 in single binary logistic regression analyses were added to the multiple model using a forward procedure. A cut-off value of P < .1 was established to retain variables in the final model. Nagelkerke's R² and Hosmer-Lemeshow statistic were calculated as measures of model fit.

RESULTS

The sample comprised of 206 patients, of which 95 presented with IAD category 2, and 111 were free of IAD. Seven independent risk factors were identified: liquid stool [odds ratio (OR) 4.69; 95% confidence interval (CI) 2.28-9.62], diabetes (OR 2.89; 95% CI 1.34-6.27), age (OR 1.05; 95% CI 1.02-1.08), smoking (OR 2.67; 95% CI 1.21-5.91), non-use of diapers (OR 2.97; 95% CI 1.39-6.33), fever (OR 2.60; 95% CI 1.23-5.53), and low oxygen saturation (OR 2.15; 95% CI 1.03-4.48). Nagelkerke's R² was 0.377. The Hosmer-Lemeshow statistic indicated no significant difference between the observed and expected values (p = .301).

CONCLUSIONS

Liquid stool, diabetes, age, smoking, non-use of diapers, fever, and low oxygen saturation were independently associated with IAD category 2 in critically ill patients with fecal incontinence.

The effect of a natural food based tube feeding in minimizing diarrhea in critically ill neurological patients

BACKGROUND & AIMS

Diarrhea has negative consequences for patients, health care staff and health care costs when neurological patients are fed enterally over long periods. We examined the effect of tube feeding with natural foods in reducing the number of fluid stool evacuations and diarrhea in critically ill neurological patients.

METHODS

A multicenter, prospective, open-label and randomized controlled trial (RCT) was conducted at facilities in Germany specializing in early rehabilitation after neurological damage. Patients of the INTERVENTION group were fed by tube using a commercially available product based on real foods such as milk, meat, carrots, whereas CONTROL patients received a standard tube-feed made of powdered raw materials. All received enteral nutrition over a maximum of 30 days. The number of defecations and the consistency of each stool according to the Bristol Stool Chart (BSC) were monitored. In addition, daily calories, liquids and antibiotic-use were recorded.

RESULTS

118 Patients who had suffered ischemic stroke, intracerebral hemorrhage, traumatic brain injury or hypoxic brain damage and requiring enteral nutrition were enrolled; 59 were randomized to receive the intervention and 59 control feed. There were no significant differences in clinical screening data, age, sex, observation period or days under enteral nutrition between the groups. Patients in both groups received equivalent amount of calories and fluids. In both groups antibiotics were frequently prescribed (69.5% in the INTERVENTION group and 75.7% in the CONTROL group) for 10-11 days on average. In comparison to the CONTROL group, patients in the INTERVENTION group had a significant reduction of the number of watery stool evacuations (type 7 BSC) (minus 61%, IRR = 0.39, p < 0.001). Further statistical evaluations using the following corrections: major diarrhea-associated confounders (number and duration of antibiotics); shorter observation period of 15 days; excluding patients with Clostridium difficile associated diarrhea (CDAD) and the Per Protocol Population, confirmed the primary hypothesis. The number of days with diarrhea was significantly lower in the INTERVENTION group (0.8 ± 1.60 days versus 2.0 ± 3.46 days).

CONCLUSIONS

Tube feeding with natural based food was effective in reducing the number of watery defecations and diarrhea in long term tube-fed critically ill neurological patients, compared to those fed with standard tube feeding.

Incontinence-associated dermatitis in the critically ill patient: an intensive care perspective

BACKGROUND

Incontinence-associated dermatitis is a skin disorder evident as a complication of incontinence. It is characterized by perineal, buttock and groin erythema and skin breakdown. Incontinence-associated dermatitis is a ubiquitous, nosocomial condition commonly present in critically ill patients in the intensive care unit. Critically ill patients, by the nature of their critical illness and therapies used to treat their presenting condition, are commonly predisposed to faecal incontinence and are consequently at high risk of developing incontinence-associated dermatitis. However, this condition is under-explored and under-reported in the intensive care literature.

OBJECTIVE

The aim of this paper is to provide a review of the literature relating to incontinence-associated dermatitis from the critically ill patients in the intensive care setting.

DISCUSSION

There is a paucity of literature addressing this condition in the intensive care context, with only 11 studies identified. This paper will provide an overview of the definitions, prevalence and incidence of incontinence-associated dermatitis. Furthermore, an exposition of incontinence-associated dermatitis from the critically ill patient and intensive care nursing perspectives will be presented through a review of the skin barrier function, clinical presentation, risk factors, clinical assessment and severity categorization, prevention and management of incontinence-associated dermatitis.

CONCLUSION

It is imperative that critical care nurses have an appreciation of incontinence-associated dermatitis as a common, yet preventable condition, and are equipped with knowledge to appropriately prevent and manage this common complication.

Effects of fiber and probiotics on diarrhea associated with enteral nutrition in gastric cancer patients: A prospective randomized and controlled trial

BACKGROUND AND OBJECTIVES

Diarrhea is a common complication of enteral nutrition (EN), which affects recovery and prolongs the length of hospital stay (LOHS). To investigate the effect of fiber and probiotics in reducing diarrhea associated with EN in postoperative patients with gastric cancer (GC), the authors designed this prospective randomized-controlled trial.

METHODS AND STUDY DESIGN

This study included 120 patients with GC, and the patients were classified into 3 groups via random picking of envelopes: fiber-free nutrition formula (FF group, n = 40), fiber-enriched nutrition formula (FE group, n = 40), and fiber- and probiotic-enriched nutrition formula (FEP group, n = 40). All patients were given EN formulas for 7 consecutive days after surgery.

RESULTS

The number of diarrhea cases was higher in the FF group than in the FE group (P = .007). The FEP group had a lower number of diarrhea cases compared with the FE group (P = .003). Patients in the FE group had a significantly shorter first flatus time than the FF group (P = .002). However, no significant difference was observed between the FE group and FEP group (P = .30). Intestinal disorders were similar between the FE group and FF group (P = .38). The FEP group had a lower number of intestinal disorder cases than the FF group (P = .03). LOHS in the FE and FEP groups was shorter than that in the FF group (P = .004; P < .001). However, no significant difference was observed between the FE and FEP groups (P = .28). In addition, no significant difference was observed between the 3 groups in terms of total lymphocyte count, albumin, prealbumin, and transferrin levels on day 7 of enteral feeding.

CONCLUSIONS

The combination of fiber and probiotics was significantly effective in treating diarrhea that is associated with EN in postoperative patients with GC.

An interventional skin care protocol (InSPiRE) to reduce incontinence-associated dermatitis in critically ill patients in the intensive care unit: A before and after study

AIM

This study aimed to test the effectiveness of a bundle combining best available evidence to reduce the incidence of incontinence-associated dermatitis occurrences in critically ill patients.

METHODS

The study used a before and after design and was conducted in an adult intensive care unit of an Australian quartenary referral hospital. Data, collected by trained research nurses, included demographic and clinical variables, skin assessment, incontinence-associated dermatitis presence and severity. Data were analysed using descriptive and inferential statistics.

RESULTS

Of the 207 patients enrolled, 146 patients were mechanically ventilated and incontinent thus eligible for analysis, 80 with 768days of observation in the after/intervention group and 66 with 733days of observation in the before group. Most patients were men, mean age 53 years. Groups were similar on demographic variables. Incontinence-associated dermatitis incidence was lower in the intervention group (15%; 12/80) compared to the control group (32%; 21/66) (p=0.016). Incontinence-associated dermatitis events developed later in the intensive care unit stay in the intervention group (Logrank=5.2, p=<0.022).

CONCLUSION

This study demonstrated that the use of a bundle combining best available evidence reduced the incidence and delayed the development of incontinence-associated dermatitis occurrences in critically ill patients. Systematic ongoing patient assessments, combined with tailored prevention measures are central to preventing incontinence-associated dermatitis in this vulnerable patient group.

ASPEN Safe Practices for Enteral Nutrition Therapy [Formula: see text]

Enteral nutrition (EN) is a valuable clinical intervention for patients of all ages in a variety of care settings. Along with its many outcome benefits come the potential for adverse effects. These safety issues are the result of clinical complications and of process-related errors. The latter can occur at any step from patient assessment, prescribing, and order review, to product selection, labeling, and administration. To maximize the benefits of EN while minimizing adverse events requires that a systematic approach of care be in place. This includes open communication, standardization, and incorporation of best practices into the EN process. This document provides recommendations based on the available evidence and expert consensus for safe practices, across each step of the process, for all those involved in caring for patients receiving EN.

Risk factors for diarrhea in critically ill patients during enteral nutrition

AIM: To investigate the risk factors for diarrhea in critically ill patients during enteral nutrition.

METHODS: One hundred and eighty-five critically ill patients treated at our intensive care unit (ICU) from January 2014 and December 2015 were enrolled for the study and divided into either an observation group (diarrhea) or a control group (non-diarrhea) according to the Hart diarrhea scoring method. General information, enteral nutrition and treatment data were compared between the two groups. Multivariate logistics regression analysis was performed to screen out risk factors for diarrhea.

RESULTS: Diarrhea occurred in 105 (56.8%) cases, most of which occurred in the first and second days after enteral nutrition and lasted 1-2 d. Hospital stay, the incidence of hypoalbuminemia, enteral nutrition infusion time, infusion volume, the rate of fasting before enteral nutrition, time of using antibiotics, application of a variety of antibiotics, the rates of using acid-inhibitory drug and oral potassium preparation in the observation group were significantly higher than those in the control group (P < 0.05), and the rate of gradually increasing enteral nutrition preparations in the observation group was significantly lower than that in the control group (P < 0.05). There was a significant difference in the infusion speed between the two groups (P < 0.05). Hypoalbuminemia, fasting before enteral nutrition, application of acid-inhibitory drug and oral potassium preparation were independent risk factors for diarrhea (P < 0.05), and gradually increasing enteral nutrition preparations was an independent protective factor (P < 0.05).

CONCLUSION: For critically ill patients given enteral nutrition, hypoalbuminemia, fasting before enteral nutrition, application of acid-inhibitory drug and oral potassium preparation could significantly increase the risk of diarrhea. Gradual increasing of enteral nutrition preparations is recommended to reduce the risk of diarrhea.

The burden of diarrhea in the intensive care unit (ICU-BD). A survey and observational study of the caregivers' opinions and workload

BACKGROUND

Diarrhea as a common complication affects 14% patients in our intensive care unit. Risk factors for diarrhea and its clinical consequences for patients are well known, but the impact of diarrhea on caregivers' workload remains undocumented.

OBJECTIVES

This study aims at establishing the impact of diarrhea on costs and human burden in intensive care unit caregivers.

DESIGN

A survey and observational study.

SETTINGS

A mixed 36-bed medical and surgical intensive care unit.

PARTICIPANTS

All intensive care unit caregivers (nurses and nursing aides).

METHODS

A questionnaire was designed by a multidisciplinary team and completed by intensive care unit caregivers analyzing the clinical and human impact of diarrhea on their workload. Time measurements for the management of liquid stools were performed. Human related costs of diarrhea were analyzed according to caregivers' years of clinical experience.

RESULTS

Questionnaires were completed by 146 of 204 intensive care unit caregivers (75% nurses; 73% nursing aides). Dealing with diarrhea patients is a painful aspect of their work (69% nurses) with tiredness as main feeling and a source of conflict or misunderstanding among caregivers. The mean time measurement for managing one liquid stool in 50 diarrhea episodes was 17min and 33s, involving an average of 1.4 nurses and 0.8 nursing aides. Average human resources cost burden was 26.60 CHF per liquid stool.

CONCLUSION

Dealing with diarrhea increases workload for intensive care unit caregivers with consequences on their well-being. Human related costs of diarrhea are substantial and highlight the economic burden of diarrhea episodes in the intensive care unit. A multidisciplinary approach and specific protocols could positively impact the burden of diarrhea in the intensive care unit.

Gastric residual volume management in critically ill mechanically ventilated patients: A literature review

Measured gastric residual volume (GRV) is most commonly used as a marker to guide enteral feeding rate and prevention of pulmonary aspiration in gastric-fed, mechanically ventilated intensive care unit patients. However, there is little consensus on the practice standard, and controversies exist regarding its implications.

A total of 17 papers were reviewed to evaluate the factors affecting the accuracy of GRV measurement, GRV measurement practices, and its correlations with clinically important complications. Multiple factors affect the accuracy of GRV measurement. GRV threshold and assessment frequency remain undefined. No direct correlation between measured GRV and incidences of pulmonary aspiration or pneumonia was found. However, higher incidences of pulmonary aspiration were observed in cases of higher GRV.

Not measuring GRV could result in patient harm. Reducing GRV prior to position change and procedures associated with high risk for regurgitation could prevent aspiration incidences.

Enteral Nutrition for Adults in the Hospital Setting

In patients unable to tolerate oral intake, multiple options of nutrient delivery are available to the clinician. Administration of enteral nutrition (EN) has long been considered the standard of care for nutrition support among patients unable to meet energy and protein requirements orally. Healthcare practitioners must make careful decisions related to ordering, administering, and monitoring EN therapy. In the hospital setting, the registered dietitian is a key resource in enteral formula selection and method of administration, monitoring for and troubleshooting EN-related complications, and transitioning to oral feeding. The hospital setting also presents many unique challenges in providing optimal nutrition to the enterally fed patient.

Gastroenteric tube feeding: Techniques, problems and solutions

Gastroenteric tube feeding plays a major role in the management of patients with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, and patients who are critically ill. However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.

Diarrhoea in the ICU: respective contribution of feeding and antibiotics

Introduction

Diarrhoea is frequently reported in the ICU. Little is known about diarrhoea incidence and the role of the different risk factors alone or in combination. This prospective observational study aims at determining diarrhoea incidence and risk factors in the first 2 weeks of ICU stay, focusing on the respective contribution of feeding, antibiotics, and antifungal drugs.

Methods

Out of 422 patients consecutively admitted into a mixed medical–surgical ICU during a 2-month period, 278 patients were included according to the following criteria: ICU stay >24 hours, no admission diagnosis of gastrointestinal bleeding, and absence of enterostomy or colostomy. Diarrhoea was defined as at least three liquid stools per day. Diarrhoea episodes occurring during the first day in the ICU, related to the use of laxative drugs or Clostridium difficile infection, were not analysed. Multivariate and stratified analyses were performed to determine diarrhoea risk factors, and the impact of the combination of enteral nutrition (EN) with antibiotics or antifungal drugs.

Results

A total of 1,595 patient-days were analysed. Diarrhoea was observed in 38 patients (14%) and on 83 patient-days (incidence rate: 5.2 per 100 patient-days). The median day of diarrhoea onset was the sixth day, and 89% of patients had ≤4 diarrhoea days. The incidence of C. difficile infection was 0.7%. Diarrhoea risk factors were EN covering >60% of energy target (relative risk = 1.75 (1.02 to 3.01)), antibiotics (relative risk = 3.64 (1.26 to 10.51)) and antifungal drugs (relative risk = 2.79 (1.16 to 6.70)). EN delivery per se was not a diarrhoea risk factor. In patients receiving >60% of energy target by EN, diarrhoea risk was increased by the presence of antibiotics (relative risk = 4.8 (2.1 to 13.7)) or antifungal drugs (relative risk = 5.0 (2.8 to 8.7)).

Conclusion

Diarrhoea incidence during the first 2 weeks in a mixed population of patients in a tertiary ICU is 14%. Diarrhoea risk factors are EN covering >60% of energy target, use of antibiotics, and use of antifungal drugs. The combination of EN covering >60% of energy target with antibiotics or antifungal drugs increases the incidence of diarrhoea.

Psychometric properties of DAPonDEN: definitions, attitudes and practices in relation to diarrhea during enteral nutrition questionnaire

OBJECTIVES

To investigate the psychometric properties of the developed 21 item questionnaire to measure definitions, attitudes and management practices in relation to diarrhea during enteral nutrition (DAPonDEN).

METHODS

Data were analyzed using exploratory factor analysis from a cross sectional study of 102 nurses aged 18 and over, conducted from December 2011 to February 2012 in Malaysia. Face and content validity of DAPonDEN were first evaluated by few expert panels and patients. For this study, adult nurses were recruited from the adult wards.

RESULTS

In the final model, three items in DAPonDEN were dropped. In the exploratory factor analysis, five factors were extracted that explained a total of 55% of the variation in the remaining 18 items. The Kaiser-Meyer-Olkin (KMO) value was 0.723. For definition, there were two underlying factors: 'Key items in defining diarrhea' and 'non-key items in defining diarrhea'. For attitude there was a single factor. For practice, there were two underlying factors: 'enteral nutrition (EN) related' and 'awareness related'.

CONCLUSION

The items in each of the underlying dimensions seem to measure the respective concepts for definition, attitude and practices adequately. The 18-items DAPonDEN instrument can be a suitable education tool to be used in relation to diarrhea during EN.

A case of pressure ulceration and associated haemorrhage in a patient using a faecal management system

Diarrhoea is a difficult patient problem to manage in the intensive care setting, causing odour, discomfort and embarrassment for the patient and potential for loss of skin integrity and cross contamination. Caring for these patients is resource-intensive. A recently developed product for the management of faecal incontinence is the Flexi-Seal Faecal Management System (FMS(©)). Whilst this product is usually effective for managing diarrhoea, there are uncommon but serious complications associated with its use. Rectal bleeding attributed to pressure ulceration of the rectal mucosa can be severe, especially in conjunction with the use of anticoagulation. We report a case of severe rectal bleeding requiring surgical intervention and administration of large amounts of blood products, caused by pressure ulceration as a result of the use of a Flexi-Seal FMS(©). The case report is followed by a review of the literature. Similar complications have been described by others. Although, based on the number of reported complications, the incidence of serious complications appears to be low, a publication bias cannot be ruled out. Knowledge of the complications associated with the device is important for evaluating the appropriateness of insertion and for ensuring the safe and effective on going care of patients using Flexi-Seal FMS(©).
