A Multi-Site, International Audit of Malnutrition Risk and Energy and Protein Intakes in Patients Undergoing Treatment for Head Neck and Esophageal Cancer: Results from INFORM.

Patients with foregut tumors are at high risk of malnutrition. Nutrition care focuses on identifying individuals at risk of malnutrition and optimizing nutrient intake to promote the maintenance of body weight and lean body mass. This multi-center prospective, longitudinal study audited nutrition care practices related to screening for risk of malnutrition (Patient-Generated Subjective Global Assessment Short Form; PG-SGA SF), and nutrition interventions prescribed (route; adequacy of energy and protein intakes). Audits occurred at four time periods: baseline (before treatment) and at 2, 4, and 6 months after starting cancer treatment; 170 patients (esophageal (ESO; n = 51); head and neck (HN; n = 119)) were enrolled. Nutrition risk (PG-SGA SF score ≥ 4) was prevalent at every time period: HN (baseline: 60%; 6 months 66%) and ESO (77%; 72%). Both groups had significant (p < 0.001) weight losses over the 6 month audit period (HN = 13.2% ESO = 11.4%). Enteral nutrition (EN) was most likely to be prescribed at 2 months for HN and at 4 and 6 months for ESO. Target prescribed energy and protein intakes were not met with any nutrition intervention; although adequacy was highest for those receiving EN. Nutrition care practices differed for HN and ESO cancers and there may be time points when additional nutrition support is needed.

Translating Evidence-Based Guidelines into Practice-Are We Getting It Right? A Multi-Centre Prospective International Audit of Nutrition Care in Patients with Foregut Tumors (INFORM).

Malnutrition is highly prevalent in patients with foregut tumors comprising head and neck (HNC) and esophageal (EC) cancers, negatively impacting outcomes. International evidence-based guidelines (EBGs) for nutrition care exist; however, translation of research evidence into practice commonly presents considerable challenges and consequently lags. This study aimed to describe and evaluate current international nutrition care practices compared with the best-available evidence for patients with foregut tumors who are at high risk of malnutrition. A multi-centre prospective cohort study enrolled 170 patients commencing treatment of curative intent for HNC (n = 119) or EC (n = 51) in 11 cancer care settings in North America, Europe and Australia between 2016 and 2018. Adherence criteria were derived from relevant EBG recommendations with pooled results for participating centres reported according to the Nutrition Care Model at either system or patient levels. Adherence to EBG recommendations was: good (≥80%) for performing baseline nutrition screening and assessment, perioperative nutrition assessment and nutrition prescription for energy and protein targets; moderate (≥60 to 80%) for utilizing validated screening and assessment tools and pre-radiotherapy dietitian consultation; and poor (60%) for initiating post-operative nutrition support within 24 h and also dietetic consultation weekly during radiotherapy and fortnightly for 6 weeks post-radiotherapy. In conclusion, gaps in evidence-based cancer nutrition care remain; however, this may be improved by filling known evidence gaps through high-quality research with a concurrent evolution of EBGs to also encompass practical implementation guidance. These should aim to support multidisciplinary cancer clinicians to close evidence-practice gaps throughout the patient care trajectory with clearly defined roles and responsibilities that also address patient-reported concerns.

Development of a clinical pathway for enhanced recovery in colorectal surgery: a Canadian collaboration

Summary: Enhanced Recovery After Surgery (ERAS) is a model of care that was introduced in the late 1990s by a group of surgeons in Europe. The model consists of a number of evidence-based principles that support better outcomes for surgical patients, including improved patient experience, reduced length of stay in hospital, decreased complication rates and fewer hospital readmissions. A number of Canadian surgical care teams have already adopted ERAS principles and have reported positive outcomes. Arising from the Canadian Patient Safety Institute's Integrated Patient Safety Action Plan for Surgical Care Safety, and with support from numerous partner organizations from across the country, Enhanced Recovery Canada is leading the drive to improve surgical safety across the country and help disseminate these ERAS principles. We discuss the development of a multidisciplinary clinical pathway for elective colorectal surgery to help guide Canadian clinicians.

Variations in practice patterns for adult cancer patients on home parenteral nutrition in Canada.

OBJECTIVES: Cancer has become a major indication for home parenteral nutrition (HPN). However, the use of HPN in adult cancer patients is highly variable between countries and may also differ within each country. The aim of the present study was to characterize regional variations in practice patterns for cancer patients on HPN using data from the Canadian HPN Registry. METHODS: This retrospective analysis included all cancer patients (n = 164) enrolled in the registry from 2005 to 2016. Patient demographic and clinical characteristics were described. Differences in baseline characteristics were evaluated by province and duration of HPN therapy. Survival was estimated with the Kaplan-Meier method and compared among different tumor types and provinces using the log-rank test. RESULTS: The most common tumors were gastrointestinal (54.2%) and gynecologic (31.8%). Most patients were from the provinces of Ontario (54.3%) and Alberta (41.5%). Patients who received HPN for ≥3 mo (64.6%) had a higher baseline Karnofsky Performance Status (80 versus 50) and albumin (35 versus 26 mmol/L) compared with those on HPN for <3 mo. There were no differences in survival based on tumor category. Patients in Ontario programs had a longer median survival (11.3 versus 7.1 mo) and higher proportion of secondary indications for HPN relative to patients in Alberta programs. CONCLUSIONS: Most cancer patients on HPN have gastrointestinal or gynecologic cancers. Those surviving for ≥3 mo have better baseline characteristics. Regional variability in the prevalence, selection, and survival of cancer patients receiving HPN suggests the need for consensus on the use of HPN in this population.

Implementation of Enhanced Recovery After Surgery: a strategy to transform surgical care across a health system.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) programs have been shown to have a positive impact on outcome. The ERAS care system includes an evidence-based guideline, an implementation program, and an interactive audit system to support practice change. The purpose of this study is to describe the use of the Theoretic Domains Framework (TDF) in changing surgical care and application of the Quality Enhancement Research Initiative (QUERI) model to analyze end-to-end implementation of ERAS in colorectal surgery across multiple sites within a single health system. The ultimate intent of this work is to allow for the development of a model for spread, scale, and sustainability of ERAS in Alberta Health Services (AHS). METHODS: ERAS for colorectal surgery was implemented at two sites and then spread to four additional sites. The ERAS Interactive Audit System (EIAS) was used to assess compliance with the guidelines, length of stay, readmissions, and complications. Data sources informing knowledge translation included surveys, focus groups, interviews, and other qualitative data sources such as minutes and status updates. The QUERI model and TDF were used to thematically analyze 189 documents with 2188 quotes meeting the inclusion criteria. Data sources were analyzed for barriers or enablers, organized into a framework that included individual to organization impact, and areas of focus for guideline implementation. RESULTS: Compliance with the evidence-based guidelines for ERAS in colorectal surgery at baseline was 40%. Post implementation compliance, consistent with adoption of best practice, improved to 65%. Barriers and enablers were categorized as clinical practice (22%), individual provider (26%), organization (19%), external environment (7%), and patients (25%). In the Alberta context, 26% of barriers and enablers to ERAS implementation occurred at the site and unit levels, with a provider focus 26% of the time, a patient focus 26% of the time, and a system focus 22% of the time. CONCLUSIONS: Using the ERAS care system and applying the QUERI model and TDF allow for identification of strategies that can support diffusion and sustainment of innovation of Enhanced Recovery After Surgery across multiple sites within a health care system.

Changes in Home Parenteral Nutrition Practice Based on the Canadian Home Parenteral Nutrition Patient Registry.

BACKGROUND: Since 2005, the Canadian home parenteral nutrition (HPN) registry has collected data on patients' demography, outcomes, and HPN clinical practice. At annual meetings, Canadian HPN programs review and discuss results. AIM: To evaluate changes over time in patient demography, outcomes, and HPN clinical practice using the registry data. METHODS: This retrospective study evaluated 369 patients who were prospectively entered in the registry. Two periods were compared for the first data entry: 2005-2008 (n = 182) and 2011-2014 (n = 187). Patient demography, indications for HPN, HPN regimen, nutrition assessment, vascular access, and number of line sepsis per 1000 catheter days were evaluated. RESULTS: For 2011-2014 compared with 2005-2008, indications for HPN changed significantly, with an increased proportion of patients with cancer (37.9% vs 16.7%) and with fewer cases of short bowel syndrome (32% vs 65.5%); line sepsis rate decreased from 1.58 to 0.97 per 1000 catheter days; and the use of tunneled catheters decreased from 64.3% to 38.0% and was no longer the most frequently chosen vascular access method. In contrast, the proportion of peripherally inserted central catheters increased from 21.6% to 52.9%. In addition, there was a reduction in number and days of hospitalizations related to HPN, and favorable changes were noted in the prescription of energy, proteins, and trace elements. CONCLUSION: The Canadian HPN registry is useful in tracking trends in demography, outcomes, and clinical practice. Results suggest a shift in patient demography and line access with improvement in line sepsis, hospitalizations, and HPN prescriptions.

Implementation of Enhanced Recovery After Surgery (ERAS) Across a Provincial Healthcare System: The ERAS Alberta Colorectal Surgery Experience.

BACKGROUND: Enhanced recovery after surgery (ERAS) colorectal guideline implementation has occurred primarily in standalone institutions worldwide. We implemented the guideline in a single provincial healthcare system, and our study examined the effect of the guideline on patient outcomes [length of stay (LOS), complications, and 30-day post-discharge readmissions] across a healthcare system. METHODS: We compared pre- and post-guideline implementation in consecutive elective colorectal patients, ≥ 18 years, from six Alberta hospitals between February 2013 and December 2014. Participants were followed up to 30 days post discharge. We used summary statistics, to assess the LOS and complications, and multivariate regression methods to assess readmissions and to estimate cost impacts. RESULTS: A total of 1333 patients (350 pre- and 983 post-ERAS) were analysed. Of this number, 55 % were males. Median overall guideline compliance was 39 % in pre- and 60 % in post-ERAS patients. Median LOS was 6 days for pre-ERAS compared to 4.5 days in post-ERAS patients with the longest implementation (p value <0.0001). Adjusted risk ratio (RR) was 1.71, 95 % CI 1.09-2.68 for 30-day readmission, comparing pre- to post-ERAS patients. The proportion of patients who developed at least one complication was significantly reduced, from pre- to post-ERAS, difference in proportions = 11.7 %, 95 % CI 2.5-21.0, p value: 0.0139. The net cost savings attributable to guideline implementation ranged between $2806 and $5898 USD per patient. CONCLUSION: The findings in our study have shown that ERAS colorectal guideline implementation within a healthcare system resulted in patient outcome improvements, similar to those obtained in smaller standalone implementations. There was a significant beneficial impact of ERAS on scarce health system resources.

An economic evaluation of the Enhanced Recovery After Surgery (ERAS) multisite implementation program for colorectal surgery in Alberta

BACKGROUND: In February 2013, Alberta Health Services established an Enhanced Recovery After Surgery (ERAS) implementation program for adopting the ERAS Society colorectal guidelines into 6 sites (initial phase) that perform more than 75% of all colorectal surgeries in the province. We conducted an economic evaluation of this initiative to not only determine its cost-effectiveness, but also to inform strategy for the spread and scale of ERAS to other surgical protocols and sites. METHODS: We assessed the impact of ERAS on patients’ health services utilization (HSU; length of stay [LOS], readmissions, emergency department visits, general practitioner and specialist visits) within 30 days of discharge by comparing pre- and post-ERAS groups using multilevel negative binomial regressions. We estimated the net health care costs/savings and the return on investment (ROI) associated with those impacts for post-ERAS patients using a decision analytic modelling technique. RESULTS: We included 331 pre- and 1295 post-ERAS patients in our analyses. ERAS was associated with a reduction in all HSU outcomes except visits to specialists. However, only the reduction in primary LOS was significant. The net health system savings were estimated at $2 290 000 (range $1 191 000–$3 391 000), or $1768 (range $920–$2619) per patient. The probability for the program to be cost-saving was 73%–83%. In terms of ROI, every $1 invested in ERAS would bring $3.8 (range $2.4–$5.1) in return. CONCLUSION: The initial phase of ERAS implementation for colorectal surgery in Alberta is cost-saving. The total savings has the potential to be more substantial when ERAS is spread for other surgical protocols and across additional sites.

The Canadian Home Total Parenteral Nutrition (HTPN) Registry: vitamin K supplementation and bone mineral density.

BACKGROUND: Vitamin K supplementation improves bone health, and its absence might be associated with low bone mineral density (BMD). The authors aim to assess vitamin K supplementation practices in Canadian home parenteral nutrition (HPN) programs and their relationship with BMD. METHODS: This is a cross-sectional study of 189 patients from the Canadian HPN registry. RESULTS: All 189 patients studied received M.V.I.-12, which does not contain vitamin K. Of those, 41.3% were supplemented with 10 mg of intravenous vitamin K (VK+) weekly, whereas the others did not receive vitamin K except via lipid emulsion (VK-). Short bowel syndrome accounted for 69% of VK+ and 46% of VK- patients. On univariate analysis, VK+ patients had substantially lower body mass index (BMI) and received lower bisphosphonate infusion than did VK-patients. There were no statistically significant differences in HPN calcium or lipid content, liver function test results, age, sex, or reason for HPN between the 2 groups. Patients who were VK+ had higher lumbar spine T scores and hip T scores than did VK-patients. General linear modeling analysis, adjusted for BMI, age, PN magnesium, PN phosphate, PN calcium, and bisphosphonate as possible predictors of BMD, showed a trend toward better hip T scores (P = .063) for VK+ patients compared with VK- patients. CONCLUSION: In HPN patients supplemented with vitamin K, the trend toward a better hip BMD compared with no supplementation suggests a role for vitamin K in preserving BMD. This requires further study.

The Intersociety Professional Nutrition Education Consortium and American Board of Physician Nutrition Specialists: what have we learned?

A significant obstacle to nutrition literacy among physicians is a paucity of physician nutrition specialists (PNSs) on medical school faculties who can effectively advocate for change in medical school and residency curricula, and who can serve as role models for incorporating nutrition into patient care. To address these issues, the Intersociety Professional Nutrition Education Consortium (IPNEC) developed a paradigm for PNSs that is designed to attract more physicians into the field; promulgated educational standards for fellowship training of PNSs; and established a unified mechanism for certifying PNSs, the American Board of Physician Nutrition Specialists (ABPNS). With a board of directors consisting of members nominated by 7 professional nutrition societies in addition to at-large members, the ABPNS incorporates broad participation by all professional nutrition societies that have substantial physician members. The ABPNS certificate is intended to be the premier comprehensive credential for physicians who wish to identify nutrition as an area of expertise. Certification is equally accessible to physicians with backgrounds in any of the specialties and subspecialties relevant to clinical nutrition. This article outlines the history and features of IPNEC and ABPNS and the consensus paradigm, training standards, and certification process they developed. We discuss achievements, opportunities, and challenges facing the maintenance of a consensus-based certification body in order to inform future initiatives designed to expand the number of physician nutrition specialists.

Home enteral nutrition: outcomes relative to indication.

BACKGROUND: Home enteral nutrition (HEN) is a life-sustaining therapy for patients who are unable to meet nutrient needs by oral intake, who have a functional gastrointestinal (GI) tract, and who are able to remain in their own home. The objective of this study was to identify whether the indication for HEN is related to reason for discharge from a HEN program. METHODS: A retrospective chart review of all patients admitted to the multidisciplinary Northern Alberta Home Enteral Nutrition Support Program between January 1, 1999 and January 1, 2005 was performed. Detailed information on the indication for HEN, length of time on program, and reason for discharge was collected and statistically analyzed. RESULTS: Over the 6-year period, 727 adult patients were admitted. Major diagnostic categories for HEN were cancer, neurological disorders, and GI disorders. Median duration of HEN for cancer patients was 122 (range, 1-1259) days, duration for neurological disorders was 187 (range, 1-1752) days, and duration for GI disorders was 161 (range, 1-1849) days. Death was the main reason for discharge in patients with cancer and neurological disorders. Patients with GI disorders were most likely to initiate oral intake and least likely to be discharged because of death. CONCLUSIONS: Indications for HEN are related to outcome-specifically, time to discontinuation of enteral nutrition and reason for discharge, including return to oral intake and death.

Medical students' perceptions of nutrition education in Canadian universities.

Patients routinely seek physicians' guidance about diet and the relation between nutrition and the prevention and treatment of disease. However, the adequacy of nutrition instruction in undergraduate medical education is questionable. The purpose of this study was to investigate Canadian medical students' perceptions of and satisfaction with their education in nutrition. At 9 universities across Canada, a 23-item survey questionnaire was distributed in English and French to undergraduate medical students after at least 8 months of medical school. Overall, 9 of 17 universities participated in the survey, and 933 of the 3267 medical students approached completed the survey (response rate, 28.6%). Mean satisfaction with nutrition instruction received during medical school was 4.7 (+/-0.06) on a scale of 1-10, where 1 is very dissatisfied and 10 is very satisfied, and there were significant differences among schools (p < 0.0001). Students were comfortable in their ability to counsel patients regarding basic nutrition concepts and the role of nutrition in prevention of disease, but were much less comfortable discussing the role of nutrition in the treatment of disease and nutrient requirements across the lifecycle, and in identifying credible sources of nutrition information. Of the 933 respondents, 87.2% believe that their undergraduate program should dedicate more time to nutrition education. The amount of nutrition instruction correlated with student satisfaction (p < 0.0001), but varied among schools. A significant number of students are dissatisfied with the nutrition education they receive and their ability to provide relevant and appropriate nutrition counselling. This study paves the way for further discussions and development of strategies to improve nutrition education in medical schools in Canada.

2004 MacLean-Mueller prize enteral or parenteral nutrition for severe pancreatitis: a randomized controlled trial and health technology assessment.

BACKGROUND: The optimal route of nutrition in severe pancreatitis is controversial. Parenteral nutrition (PN) is preferred, but enteral nutrition (EN) promises to attenuate inflammation and prevent sepsis. We hypothesized that EN was at least equivalent to PN in reducing inflammation, providing effective nutrition and being cost-effective. METHODS: We conducted a randomized controlled trial comparing PN to EN in pancreatitis in an academic, multi-institutional, tertiary care health system. We screened 728 consecutive patients. Twenty-eight patients with a Ranson's score greater than 2 who did not tolerate clear fluids 4 days after admission were randomized: 18 to PN and 10 to EN. Both groups were provided daily 105 kJ (25 kcal)/kg and 1.5 g/kg of protein, respectively, until they could tolerate a regular diet. RESULTS: C-reactive protein in EN patients was reduced by 50% 5 days faster than PN patients (Wilcoxon test, p = 0.09). Both groups received a similar number of kilojoules and achieved near normal prealbumin and 24-hour urinary nitrogen values. Neither regimen caused a change in cholecystokinin levels. Overall mortality was 4.9% (3 patients in the PN group). In 5 patients (4 PN, 1 EN) there were infected pancreatic collections. Nine EN patients dislodged the nasojejunal tube. EN had an average cost of dollar 1375 per patient compared with dollar 2608 for PN (p = 0.08). After sensitivity analysis, EN cost dollar 957 compared with dollar 2608 for PN (p = 0.03). CONCLUSIONS: EN or PN is safe and provides adequate nutrition in severe pancreatitis. EN shows a trend toward faster attenuation of inflammation, with fewer septic complications and is the dominant therapy in terms of cost-effectiveness. This study favours EN for nutritional support in severe pancreatitis.

Nonalcoholic fatty liver disease in patients investigated for elevated liver enzymes.

Nonalcoholic fatty liver disease (NAFLD) is a common diagnosis among patients referred to gastroenterology and hepatology clinics for the evaluation of elevated liver enzymes. The diagnosis of NAFLD is supported by blood work to exclude other liver diseases, and by ultrasound evidence of fat in the liver in patients without a significant history of alcohol intake. The gold standard, however, is a liver biopsy to show the typical histological features of NAFLD, which are almost identical to those of alcohol-induced liver damage and can range from mild steatosis to cirrhosis. A variety of retrospective series have linked NAFLD to obesity, diabetes, hyperlipidemia, total parenteral nutrition, jejunoileal bypass surgery and certain medications. A subset of patients with NAFLD that had an initial presentation of elevated liver enzymes was studied. Two hundred and two patients were reviewed, of whom 49 met the inclusion criteria including a liver biopsy. Patients were excluded if insufficient data were available, if the patients had a significant history of ethanol intake or if they had other coexisting liver disease. These patients were seen between 1996 and 2000 in gastroenterology and hepatology clinics in two community hospitals and one regional liver transplant centre in Edmonton, Alberta. NAFLD was associated with a spectrum of changes in the liver ranging from mild steatosis to more significant steatosis with inflammation and fibrosis. Cases of NAFLD with steatosis and mixed inflammatory infiltration but lacking ballooning degeneration or fibrosis were prevalent in young (20 to 40 years of age) patients with no other significant medical history except for obesity. NAFLD with biopsies showing significant fibrosis and ballooning cell degeneration was associated with obesity, diabetes and older age. It was concluded that, in this predominantly outpatient setting, age over 40 years and diabetes at any age are risk factors for both nonalcoholic steatohepatitis and nonalcoholic steatohepatitis with cirrhosis. It is therefore recommended that patients with raised liver enzymes and suspected NAFLD be targeted for liver biopsy in their evaluation.
