Early enteral nutrition within 24 hours or between 24 and 72 hours for acute pancreatitis: evidence based on 12 RCTs

Efficacy of DaXianXiong Decoction in Preventing the Progression of Acute Pancreatitis Severity: Protocol for a Randomized Controlled Trial

BACKGROUND

Low- and middle-income countries are facing an increase in the incidence of acute pancreatitis (AP)-characterized by rapid onset, fast progression, high rate of severity, and high mortality. Progression of AP into severe AP (SAP) results in a series of complications such as organ dysfunction, local abscesses, pseudocysts, and necrosis. Although the treatment of AP is primarily supportive, including fluid resuscitation and organ support, there is still a lack of consensus on the optimal management regimen for fluid therapy, and strategies to promote gastrointestinal recovery remain limited. As no effective intervention measure has yet been developed, supportive therapy remains the primary approach for the early treatment of AP. DaXianXiong decoction is a widely used traditional Chinese medicine formulation; however, limited research has been conducted on its clinical efficacy.

OBJECTIVE

This study aims to evaluate the efficacy and safety of DaXianXiong decoction in preventing AP from progressing to SAP, assessing its impact on SAP incidence, clinical severity scores, inflammation markers, and gastrointestinal function, and providing evidence for AP management.

METHODS

This study is a randomized, double-blind, placebo-controlled, single-center clinical trial. The primary outcomes will include the incidence of SAP, modified computed tomography severity index score, APACHE II (Acute Physiology and Chronic Health Evaluation II) score, modified Marshall score, and levels of the inflammation factor. The secondary outcomes will include the effect of the gastrointestinal dysfunction treatment. Evaluations will be conducted at baseline; 24 hours after the intervention; and on days 3, 7, and 28 after the intervention in both groups. A total of 60 eligible patients will be randomly allocated in a 1:1 ratio to the intervention group and the control group. Both groups will receive standard Western medical treatment for pancreatitis. The intervention group will additionally receive DaXianXiong decoction, while the control group will receive a placebo similar to the decoction.

RESULTS

This study has been funded by the Performance Incentive Project of Scientific Research Institutions in Chongqing. The trial was registered in April 2024, and data analysis is expected to be completed by April 2025. The study results will be presented at both national and international conferences and published in peer-reviewed journals.

CONCLUSIONS

This trial will help us assess the effectiveness and safety of DaXianXiong decoction in patients with AP and provide clinical evidence on the efficacy and safety of DaXianXiong decoction in preventing the progression of AP to SAP. By evaluating its impact, the findings will contribute to the understanding of DaXianXiong decoction as an adjunct therapy in AP management and may offer a novel complementary treatment strategy for AP, potentially improving patient outcomes and reducing complications.

S3-Leitlinie Klinische Ernährung bei Pankreaserkrankungen

Sowohl die akute als auch die chronische Pankreatitis sind häufige Erkrankungen, die ein erhebliches Risiko für eine Mangelernährung mit sich bringen und eine Ernährungstherapie erfordern können. In ca. 20% der akuten Pankreatitiden tritt eine nekrotisierende Pankreatitis auf, die mit einer erhöhten Morbidität und Mortalität verbunden ist. Hier ist oftmals eine Ernährungstherapie mittels einer enteralen oder parenteralen Ernährung notwendig, die neben medikamentösen, endoskopischen, radiologischen oder chirurgischen Maßnahmen eine etablierte Säule der multimodalen Therapie darstellt.

Bei der chronischen Pankreatitis handelt es sich um eine chronische Entzündung der Bauchspeicheldrüse mit Entwicklung einer Fibrose und langfristig Atrophie des Organs. Bauchschmerzen, die zu einer verminderten oralen Aufnahme von Nährstoffen führen, sowie exokrines und endokrines Versagen sind häufige Komplikationen der Krankheit. All diese Faktoren stellen Risikofaktoren für eine Unter- bzw. Mangelernährung dar. Daher sollten Patienten mit chronischer Pankreatitis als ernährungsmedizinische Risikopatienten betrachtet, untersucht und entsprechend behandelt werden. Darüber hinaus sollte bei Patienten mit chronischer Pankreatitis auf Osteoporose und ein erhöhtes Frakturrisiko geachtet werden, und entsprechende Präventivmaßnahmen erwogen werden.

The 1st i-EUS consensus on the management of pancreatic fluid collections - Part 2

Pancreatic fluid collections (PFCs), including pancreatic pseudocysts (PPs) and walled-off pancreatic necrosis (WON), are common complications of pancreatitis and pancreatic surgery. Historically, the treatment of these conditions has relied on surgical and radiological approaches. The treatment of patients with PFCs has already focused toward an endoscopy-based approach, and with the development of dedicated lumen-apposing metal stents (LAMS), it has almost totally shifted towards interventional Endoscopic Ultrasound (EUS)-guided procedures. However, there is still limited consensus on several aspects of PFCs treatment within the multidisciplinary management. The interventional endoscopy and ultrasound (i-EUS) group is an Italian network of clinicians and scientists with special interest in biliopancreatic interventional endoscopy, especially interventional EUS. This manuscript focuses on the second part of the results of a consensus conference organized by i-EUS, with the aim of providing evidence-based guidance on several intra- and post-procedural aspects of PFCs drainage, such as clinical management and follow-up.

Nutrition therapy in critically ill patients with severe acute pancreatitis

A significant proportion of patients (10%-20%) with acute pancreatitis develop severe acute pancreatitis characterized by pancreatic necrosis, systemic inflammation, and organ failure, commonly requiring intensive care unit (ICU) admission. In this specific population, nutrition therapy is more challenging than that in the general ICU population, primarily because of inevitable gastrointestinal involvement by pancreatic inflammation. In this review, we discussed several key aspects of nutrition therapy in this population, including key pathophysiology that may impede nutrition therapy, the timing and implementation of enteral nutrition and parenteral nutrition, the importance of specific nutrient supplements, and the long-term outcomes that may be addressed by nutrition therapy.

Early vs delayed enteral nutrition or parenteral nutrition in hospitalized patients: An umbrella review of systematic reviews and meta-analyses of randomized trials

We conducted an umbrella review to summarize the existing evidence on the effect of early enteral nutrition (EEN) compared with other approaches, including delayed enteral nutrition (DEN), parenteral nutrition (PN), and oral feeding (OF) on clinical outcomes in hospitalized patients. We performed a systematic search up to December 2021, in MEDLINE (via PubMed), Scopus, and Institute for Scientific Information Web of Science. We included systematic reviews with meta-analyses (SRMAs) of randomized trials investigating EEN compared with DEN, PN, or OF for any clinical outcomes in hospitalized patients. We used "A Measurement Tool to Assess Systematic Reviews" (AMSTAR2) and the Cochrane risk-of-bias tool for assessing the methodological quality of the systematic reviews and their included trial, respectively. The certainty of the evidence was rated using the "Grading of Recommendations Assessment, Development, and Evaluation" (GRADE) approach. We included 45 eligible SRMAs contributing with a total of 103 randomized controlled trials. The overall meta-analyses showed that patients who received EEN had statistically significant beneficial effects on most outcomes compared with any control (ie, DEN, PN, or OF), including mortality, sepsis, overall complications, infection complications, multiorgan failure, anastomotic leakage, length of hospital stay, time to flatus, and serum albumin levels. No statistically significant beneficial effects were found for risk of pneumonia, noninfectious complications, vomiting, wound infection, as well as number of days of ventilation, intensive care unit days, serum protein, and pre-serum albumin levels. Our results indicate that EEN may be preferred over DEN, PN, and OF because of the beneficial effects on many clinical outcomes.

Management of Pancreatic Fluid Collections: An Evidence-based Approach

Managing pancreatic fluid collections (PFCs) remains a challenge for many clinicians. Recently, significant progress has been made in the therapy of PFCs, including improvements in technology and devices, as well as in the development of minimally invasive endoscopic techniques, many of which are proven less traumatic when compared with surgical options and more efficacious when compared with percutaneous techniques. This review will explore latest developments in the management of PFCs and how they incorporate into the current treatment algorithm.

Immediate enteral nutrition can accelerate recovery and be safe in mild acute pancreatitis: A meta-analysis of randomized controlled trials

Objectives

The effect of early enteral nutrition (EN) in patients with acute pancreatitis (AP) has been confirmed. In recent years, some researchers provided new strategy that immediate EN was offered after admission. The effect and safety of immediate EN was unclear because of the different results among studies. The study aimed to implement the meta analysis of randomized controlled trials (RCT) to confirm the effect and safety between the immediate EN group and the early refeeding group.

Methods

Four electronic databases including PubMed, EMBASE, the Cochrane Library and China National Knowledge Internet (CNKI) were searched from inception to July 2021. Endnote X7.0 software was used to manage all the relevant citations. Then data extraction and evaluation of risk of bias for included studies were performed after initial selection and full-text selection. All statistical analyses were performed by Review Manager 5.3 version software.

Results

5 randomized controlled trials (RCT) involving 372 patients were included in the present study. The meta analysis revealed that immediate EN after admission in patients with AP could significantly decrease the length of hospital stay (LOHS) (Mean difference [MD] = 2.57, 95% confidence interval [CI] = 0.41–4.72) and the intolerance of feeding (risk ratio [RR] = 0.78, 95%CI = 0.63–0.95), compared with early refeeding. But immediate EN couldn't significantly decrease the incidence of readmission after discharging (RR = 0.51, 95%CI = 0.12–2.27), the incidence of progression to severe pancreatitis (RR = 0.76, 95%CI = 0.15–3.76), the incidence of complications (RR = 1.12, 95%CI = 0.50–2.49) and the values of C-reactive protein (CRP) and leukocyte counts (MD = 1.05, 95%CI = 0.15–2.26 and MD = 0.11, 95%CI = 0.59–0.80), compared with early refeeding.

Conclusions

Compared with early refeeding, immediate EN after admission could safely reduce LOHS and intolerance of feeding in patients with AP.

Alcohol use disorder and the gut

Acute and chronic gastrointestinal problems are common in the setting of excessive alcohol use, and excessive alcohol use is associated with injury to all parts of the gastrointestinal tract. There is mounting evidence of gastrointestinal injury and increased cancer risk even from moderate alcohol consumption. The major causes of alcohol-related morbidity and mortality within the gastrointestinal system are liver disease, pancreatitis and gastrointestinal cancer. Other alcohol-related intestinal dysfunction is common but not life-threatening, leading to diarrhoea, malabsorption and nutritional deficiencies. This review describes non-neoplastic and neoplastic alcohol-related disorders of the gastrointestinal tract, omitting the liver, which has been reviewed elsewhere.

Impact of Enteral Nutrition Within 24 Hours Versus Between 24 and 48 Hours in Patients With Severe Acute Pancreatitis: A Multicenter Retrospective Study

OBJECTIVES

In patients with severe acute pancreatitis (SAP), early enteral nutrition (EN) is recommended by major clinical practice guidelines, but the exact timing for the initiation of EN is unknown.

METHODS

We conducted a post hoc analysis of the database for a multicenter (44 institutions) retrospective study of patients with SAP in Japan. The patients were classified into 3 groups according to the timing of EN initiation after the diagnosis of SAP: within 24 hours, between 24 and 48 hours, and more than 48 hours. The primary outcome was in-hospital mortality.

RESULTS

Of the 1094 study patients, 176, 120, and 798 patients started EN within 24 hours, between 24 and 48 hours, and more than 48 hours after SAP diagnosis, respectively. On multivariable analysis, hospital mortality was significantly better with EN within 48 hours than with more than 48 hours (adjusted odds ratio, 0.49; 95% confidence interval, 0.29-0.83; P < 0.001) but did not significantly differ between the groups with EN starting within 24 hours and between 24 and 48 hours (P = 0.29).

CONCLUSIONS

Enteral nutrition within 24 hours may not confer any additional benefit on clinical outcomes compared with EN between 24 and 48 hours.

Non-inferiority comparative clinical trial between early oral REFEEDING and usual oral REFEEDING in predicted mild acute biliary pancreatitis

BACKGROUND

The aim of the study was to compare the onset of oral feeding in the first 24 h after hospital admission with usual oral refeeding and determine whether the timing of the onset of oral feeding influences the recurrence of pain or alters the blood levels of pancreatic enzymes in patients with predicted mild acute biliary pancreatitis.

METHODS

This non-inferiority randomized controlled trial was carried out between September 2018 and June 2019 after receiving authorization from the ethics committee for health research. Patients with a diagnosis of predicted mild acute biliary pancreatitis were divided into Group A (early oral refeeding, EOR) and Group B (usual oral refeeding, UOR). Outcome measures included pancreatic lipase levels, the systemic inflammatory response (concentrations of leukocytes), feasibility (evaluated by abdominal pain recurrence), the presence and recurrence of gastrointestinal symptoms and the length of hospital stay.

RESULTS

Two patients in the EOR group experienced pain relapse (3.2%), and four patients in the UOR group experienced pain relapse (6.77%) after oral refeeding (p = 0.379). The presence of nausea or vomiting after the onset of oral refeeding was not different between the two groups (p = 0.293). The onset of oral refeeding was approximately 48 h later in the UOR group. The length of hospital stay was 5 days in the EOR group and 8 days in the UOR group (p = 0.042), and this difference was also manifested in higher hospital costs in the UOR group (p = 0.0235).

CONCLUSION

Compared with usual oral refeeding, early oral refeeding is safe in predicted mild acute biliary pancreatitis patients, does not cause adverse gastrointestinal events, and reduces the length of hospital stay and costs.

ESPEN guideline on clinical nutrition in acute and chronic pancreatitis

Both acute and chronic pancreatitis are frequent diseases of the pancreas, which, despite being of benign nature, are related to a significant risk of malnutrition and may require nutritional support. Acute necrotizing pancreatitis is encountered in 20% of patients with acute pancreatitis, is associated with increased morbidity and mortality, and may require artificial nutrition by enteral or parenteral route, as well as additional endoscopic, radiological or surgical interventions. Chronic pancreatitis represents a chronic inflammation of the pancreatic gland with development of fibrosis. Abdominal pain leading to decreased oral intake, as well as exocrine and endocrine failure are frequent complications of the disease. All of the above represent risk factors related to malnutrition. Therefore, patients with chronic pancreatitis should be considered at risk, screened and supplemented accordingly. Moreover, osteoporosis and increased facture risk should be acknowledged in patients with chronic pancreatitis, and preventive measures should be considered.

Effect of early enteral nutrition on laparoscopic common bile duct exploration with enhanced recovery after surgery protocols

BACKGROUND/OBJECTIVES

Protocols for enhanced recovery after surgery (ERAS) provide comprehensive and evidence-based guidelines to improve perioperative care. It remains elusive whether early enteral nutrition (EEN) will play an active role in the ERAS protocols. Laparoscopic common bile duct exploration (LCBDE) is a safe and efficient method to treat patients with bile duct stones. This study aims to assess the safety, tolerability, and outcomes of EEN after LCBDE.

SUBJECTS /METHODS

From January 2014 to April 2017, a total of 100 patients with postoperative LCBDE were chosen and randomly divided into control group and EEN group. Patients in the control group were treated with traditional management with regular diet when tolerated, while patients in the EEN group were fed with EEN 3 h after LCBDE. The patients' characteristics, time to first flatus, complications, hospitalization stay, and hospitalization expenses were assessed and compared between patients in these two groups.

RESULTS

EEN accelerated the recovery of gastrointestinal function, being indicated by reduced time to first flatus when compared with control group (P = 0.00). In accordance, the quick recovery of gastrointestinal function resulted in shorter hospitalization stay for the EEN group (P = 0.00); however, no significant difference was shown when comparing the hospitalization expenses. On another hand, early oral feeding increased the occurrence of abdominal distension and diarrhea complications (P = 0.00 and P = 0.03).

CONCLUSIONS

EEN effectively improves gastrointestinal function, but raises complications such as abdominal distension and diarrhea after LCBDE. It is recommended to implement the EEN as early as possible if the patients are reasonably expected to have high compliance.

Pediatric Pancreatitis-Molecular Mechanisms and Management

Pediatric pancreatitis is an emerging field with an increasing incidence of disease. Management of pediatric pancreatitis is understudied and, therefore, extrapolated from adult studies (although the etiologies are different). There is evidence that feeding is safe in mild acute pancreatitis in children without increased pain or length of stay. Studies are needed to predict course of the disease, disease severity, and risk of chronic pancreatitis in children.

Early or Late Feeding after ICU Admission?

The feeding of critically ill patients has recently become a controversial issue, as several studies have provided unexpected and contradictory results. Earlier beliefs regarding energy requirements in critical illness-especially during the initial phase-have been challenged. In the current review, we summarize existing evidence about fasting and the impact of early vs. late feeding on the sick organism's responses. The most important points are the non-nutritional advantages of using the intestine, and recognition that early endogenous energy production as an important player in the response must be integrated in the nutrient prescription. There is as of yet no bedside tool to monitor dynamics in metabolism and the magnitude of the endogenous energy production. Hence, an early "full-feeding strategy" exposes patients to involuntary overfeeding, due to the absence of an objective measure enabling the adjustment of the nutritional therapy. Suggestions for future research and clinical practice are proposed.

Early enteral nutrition versus delayed enteral nutrition in acute pancreatitis: A PRISMA-compliant systematic review and meta-analysis

BACKGROUND

Whether early enteral nutrition (EEN) administration is more beneficial than delayed enteral nutrition (DEN) for patients with acute pancreatitis remains controversial.

METHODS

This meta-analysis aimed to pool all relevant articles to evaluate the effects of EEN within 48 hours versus DEN beyond 48 hours on the clinical outcomes of patients with acute pancreatitis. We searched PubMed, Scopus, Embase, and Web of Science for all relevant studies and extracted the data concerning basic characteristics, complications, and mortality. We calculated the pooled risk ratio (RR), weighted mean difference, and the corresponding 95% confidential interval (95% CI) using STATA 12.0.

RESULTS

For complications, the pooled analysis showed that EEN was related to a reduced risk of multiple organ failure (RR = 0.67, 95% CI 0.46-0.99, P = .04), but not for necrotizing pancreatitis (RR = 0.95, 95% CI 0.81-1.12, P = .57). There was a tendency for decreased systemic inflammatory response syndrome in the EEN group, but the trend was not significant (RR = 0.85, 95% CI 0.71-1.02, P = .09). For mortality, no significant difference was found between the EEN and DEN groups (RR = 0.78, 95% CI 0.27-2.24, P = .64).

CONCLUSION

EEN within 48 hours is superior to DEN beyond 48 hours for patients with acute pancreatitis; however, more studies are required to verify this conclusion.

The optimal timing of enteral nutrition and its effect on the prognosis of acute pancreatitis: A propensity score matched cohort study

BACKGROUND

Early enteral nutrition (EN) can improve the prognosis of acute pancreatitis (AP), but the optimal initiation time is unknown. In this study, the optimal time of early EN was analyzed to disclose the application of early EN in AP.

METHODS

Data of 104 patients with AP were prospectively collected. With secondary infection (infected pancreatic necrosis and extrapancreatic infection) as the primary outcome variable, receiver operating characteristic (ROC) curve was used to calculate the optimal cut-off time of early EN. Propensity score matching was used to adjust for covariates. Secondary outcomes include acute gastrointestinal injury (AGI) grades, serum albumin level, and EN-related complications.

RESULTS

The ROC curve analysis showed that the third day after hospital admission was the best cut-off time of early EN (with the area under the curve of 0.744). After PS matching, the proportion of secondary infection in the early EN group was significantly lower than the late EN group (8.6% vs. 36.5%, P < 0.05). Regression analysis showed that early EN was a protective factor against secondary infection (OR 0.161, 95%CI 0.036-0.718, P < 0.05). The AGI grades and serum albumin levels were better improved in the early EN group (AGI F = 4.468, P < 0.05; serum albumin F = 3.794, P < 0.05).The proportion of EN-related abdominal distension in the early EN group was significantly lower (8.8% vs. 38.5%, P < 0.05).

CONCLUSIONS

Early EN initiated within three days could reduce the risk of secondary infection and improve the nutritional status of patients with acute pancreatitis, with a better tolerance.

Early management of acute pancreatitis: A review of the best evidence

In the 20th century early management of acute pancreatitis often included surgical intervention, despite overwhelming mortality. The emergence of high-quality evidence (randomized controlled trials and meta-analyses) over the past two decades has notably shifted the treatment paradigm towards predominantly non-surgical management early in the course of acute pancreatitis. The present evidence-based review focuses on contemporary aspects of early management (which include analgesia, fluid resuscitation, antibiotics, nutrition, and endoscopic retrograde cholangiopancreatography) with a view to providing clear and succinct guidelines on early management of patients with acute pancreatitis in 2017 and beyond.

Improving the quality of nurse-influenced patient care in the intensive care unit

BACKGROUND

Quality of care is a major focus in the intensive care unit (ICU).

AIM

To describe a nurse-initiated quality improvement (QI) project that improved the care of critically ill patients in a New Zealand tertiary ICU.

DESIGN

A framework for QI was developed and implemented as part of a practice change initiative.

METHODS

Audit data were collected, analysed and reported across seven nurse-influenced patient care standards. The seven standards were enteral nutrition delivered within 24 h of admission, timely administration of antibiotics, sedation holds for eligible patients, early mobilization and three pressure ulcer prevention strategies.

RESULTS

Comparison of audit data collected in 2014 and 2015 demonstrated improvements in five of the seven standards. Those standards with the largest practice improvements were related to the following standards: all eligible patients have enteral nutrition commenced within the first 24 h of ICU admission (3% increase); all eligible patients receive antibiotics within 30 min of prescription time (6% increase); all eligible patients have a daily sedation interruption (DSI; 24% increase); and all eligible patients are mobilized daily in their ICU stay (11% increase in percentage of patients mobilized daily).

CONCLUSIONS

The nursing-initiated QI project demonstrated improved ICU patient care in relation to early enteral nutrition commencement, DSIs and early and daily mobilizing.

RELEVANCE TO CLINICAL PRACTICE

The use of a nursing QI framework incorporating audit and feedback is one method of evaluating and enhancing the quality of care and improving patient outcomes. This initiative demonstrated the improved quality of nursing care for ICU patients, particularly in relation to early enteral nutrition commencement, timely antibiotics, DSIs and daily mobilizing. It is thus highly relevant to critical care nursing teams, particularly those working to create a culture where change is safe, achievable and valued.

Early enteral nutrition improves intestinal immune barrier in a rat model of severe acute pancreatitis

BACKGROUND

The aim of the present study was to investigate the role of early enteral nutrition (EEN) in the intestinal immune barrier in severe acute pancreatitis (SAP), and to explore its potential mechanisms.

METHODS

Sixty rats were randomly assigned to three groups: sham-operated group (SO group, n = 20), SAP group receiving EEN (SAP + EEN group, n = 20), and SAP group receiving total parental nutrition (SAP + TPN group, n = 20). SAP was induced by infusion of sodium taurocholate. Rats were killed 5 days after nutritional support. The pathological damage of the intestine was determined using HE staining. The expression of MAdCAM-1, CD⁴⁺ , and CD⁸⁺ in Peyer's lymph nodes of the distal ilium was examined by immunohistochemistry. Serum levels of endotoxin and bacterial translocation were determined.

RESULTS

The survival rate in the SAP + TPN (50%) and SAP + EEN (75%) groups was significantly lower than in the SO group (100%) (P < 0.05). The survival rate in the SAP + EEN group was significantly higher than in the SAP + TPN group (P < 0.05). The expression of MAdCAM-1, CD⁴⁺ and CD⁸⁺ in the intestine was decreased in SAP rats. EEN significantly increased the expression of MAdCAM-1, CD⁴⁺ and CD⁸⁺ compared with TPN, accompanied by a decrease in the serum levels of endotoxin and bacterial translocation.

CONCLUSIONS

Early enteral nutrition improves intestinal immune barrier, thus reducing bacterial and endotoxin translocation and improving the survival rate in SAP rats.

Timing of oral refeeding in acute pancreatitis: A systematic review and meta-analysis

BACKGROUND AND AIM

The optimal timing of oral refeeding in acute pancreatitis is unclear. This study aimed to perform a systematic review with meta-analysis of randomized controlled trials (RCTs) that compared early oral refeeding with standard oral refeeding in acute pancreatitis.

METHODS

PubMed, the Cochrane library, and the Igaku-Chuo-Zasshi database were searched in order to identify RCTs eligible for inclusion in the systematic review. The weighted mean differences (WMDs) or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.

RESULTS

Five eligible RCTs were included. Compared with standard oral refeeding, early oral refeeding significantly decreased the length of hospital stay (WMD: -2.22, 95%CI: -3.37 to -1.08, p = 0.0001). Although there was heterogeneity (I²= 56%, p = 0.06), subgroup analysis of the refeeding criteria (immediate group and hungry group) eliminated the heterogeneity. There was no significant difference between the early refeeding group and standard refeeding groups with respect abdominal pain and distension (OR 1.14; 95%CI 0.65-1.99 and OR 1.53; 95%CI 0.81-2.90).

CONCLUSIONS

Compared with standard oral refeeding, early oral refeeding safely reduced the length of hospital stay in patients with acute pancreatitis.

Malnutrition in Hospitals: It Was, Is Now, and Must Not Remain a Problem!

BACKGROUND

Malnutrition is an under-recognized problem in hospitalized patients. Despite systematic screening, the prevalence of malnutrition in the hospital did not decrease in the last few decades. The aim of our study was to evaluate the prevalence of malnutrition and to determine the explicit daily calorie intake of hospitalized patients, to identify the risk factors of developing malnutrition during hospitalization and the effect on the financial reimbursement according to the German DRG-system.

MATERIAL AND METHODS

815 hospitalized patients were included in this study. The detection of malnutrition was based on the nutritional-risk-screening (NRS) and subjective-global-assessment (SGA) scores. A trained investigator recorded the daily calorie and fluid intake of each patient. Furthermore, clinical parameters, and the financial reimbursement were evaluated.

RESULTS

The prevalence of malnutrition was 53.6% according to the SGA and 44.6% according the NRS. During hospitalization, patients received on average 759.9±546.8 kcal/day. The prevalence of malnutrition was increased in patients with hepatic and gastrointestinal disease and with depression or dementia. The most important risk factors for malnutrition were bed rest and immobility (OR=5.88, 95% CI 2.25-15.4). In 84.5% of patient records, malnutrition was not correctly coded, leading to increased financial losses according to the DRG-system (94.908 Euros).

CONCLUSIONS

Hospitalized patients suffer from inadequate nutritional therapy and the risk for developing malnutrition rises during the hospital stay. The early screening of patients for malnutrition would not only improve management of nutritional therapy but also, with adequate coding, improve financial reimbursement according to the DRG-system.
