FP2.2 - Does preoperative nutritional assessment correlate with postoperative outcomes of patients undergoing surgery due to colorectal cancer? A bicenter prospective observational study

Abstract Aims Preoperative nutritional status has been investigated as a risk factor for postoperative complications in patients undergoing surgery due to colorectal surgery. The aim of the present study was to investigate the predictive role of preoperative nutritional assessment in terms of morbidity and mortality in such patients. Methods Patients undergoing surgery due to colorectal cancer from March 2022 until March 2023 at two university surgical departments were included in the present study. Patients’ demographics and postoperative parameters, such as complications’ severity according to Clavien-Dindo classification and mortality, along with malignancy stage were reported. Preoperative nutritional assessment was conducted according to the Patient-Generated Subjective Global Assessment (PG-SGA) tool and the Geriatric Nutritional Risk Index (GNRI) tool. The present study was registered in ClinicalTrials.gov (NCT05795374). Results The present study included 159 patients with a mean age of 69 ± 12 years old. Severe malnutrition according to the PG-SGA tool was associated with advanced disease stage (66% vs 59%, p=0.006). In addition, the high risk of malnutrition according to the GNRI tool was correlated to major (Clavien-Dindo≥3) postoperative complications (19% vs 15%, p=0.026) and increased 30-day mortality (34% vs 9%, p=0.026). Conclusions Postoperative morbidity and mortality of patients undergoing surgery due to colorectal cancer seem to be associated with preoperative nutritional stratification, especially with the high malnutrition risk.

Influence of malnutrition according to the glim criteria on the chemotherapy toxicities in patients with advanced lung cancer.

Cancer-associated malnutrition is highly prevalent in advanced lung cancer, and 50% of global cancer-related deaths are attributed to cancer-associated malnutrition. Platinum-containing chemotherapy is the standard treatment for advanced lung cancer. Unfortunately, it can cause exacerbated toxicities, which can also have a negative impact on patient's prognosis and quality of life. The Global Leadership Initiative on Malnutrition (GLIM) criteria have been proposed as the world's first accepted diagnostic criteria for malnutrition. However, the effectiveness of GLIM criteria in predicting chemotherapy toxicities in patients with advanced lung cancer is unclear. The aim of this study was to apply the GLIM criteria to assess the prevalence of pre-treatment diagnosis of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) and to determine the impact of nutritional status on patient's chemotherapy toxicity. We conducted a study of hospitalized patients with pathologically and clinically diagnosed advanced NSCLC who presented to our hospital from May 2021 to January 2022. Initially, the Nutritional Risk Screening-2002 (NRS-2002) was used for nutritional risk screening, and nutritional status was assessed using the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and GLIM criteria. Chemotherapy toxicity was assessed and graded according to CTCAE5.0, and chemotherapy efficacy was assessed according to RECIST1.1. Kappa test was used to analyze the agreement between PG-SGA and GLIM criteria. Univariate and multivariate logistic regression analyses were used to determine the relationship between malnutrition and chemotherapy toxicity. A total of 215 patients with advanced NSCLC were evaluated for nutritional status. Most of the patients had normal BMI (61.86%) before the start of treatment, 40% were well-nourished as assessed by the PG-SGA tool, and 51.17% were well-nourished as assessed by GLIM criteria. Consistency analysis showed moderate agreement (Kappa = 0.463, P < 0.001) and their correlation was also moderate (Spearman, rs = 0.475, P < 0.001). The objective response rate (ORR) (P = 0.040) and disease control rate (DCR) (P < 0.001) were significantly lower in malnourished patients diagnosed according to GLIM criteria than in well-nourished patients. Multivariate analysis showed that malnutrition (OR = 1.531,95%CI 0.757-3.009; OR = 6.623,95%CI 1.390-31.567, P = 0.046) diagnosed by GLIM criteria was an independent predictor of chemotherapy toxicity. Conclusions Malnutrition diagnosed by GLIM criteria better predicts toxicity during chemotherapy, determines the degree of clinical benefit of chemotherapy, and may affect patient prognosis.

Effect of a Personalized Enteral Nutrition Protocol on the Postoperative Nutritional Status in Patients Who Underwent Oral Cancer Surgery

Differences in the implementation of the perioperative nutrition guidelines and pathways by caregivers lead to differences in enteral nutrition provided to the patients. This study investigated the effect of a personalized enteral nutrition protocol on the postoperative nutritional status of patients who underwent oral cancer surgery at Zhejiang Ningbo NO. 2 Hospital. Those who underwent surgery between July 2017 and October 2018 received routine enteral nutrition based on the Nutritional Risk Screening 2002 (routine group), while those between November 2018 and August 2021 received personalized enteral nutrition based on the Patient-Generated Subjective Global Assessment tool (personalized group). Seventy patients completed the study (routine group, n = 34; personalized group, n = 36). After surgery, the personalized group exhibited significantly greater improvements in serum albumin levels (P < 0.01) (on the 7th and 10th day) and hand grip strength (P < 0.01), higher self-care ability (P < 0.01), lower incidence of gastrointestinal reactions during enteral feeding (P < 0.05), and shorter hospital stay (P < 0.05) than the routine group. Therefore, a personalized enteral nutrition program might improve the postoperative nutritional status, shorten the hospital stay, and accelerate postoperative recovery in patients who underwent oral cancer surgery.

Screening of malnutrition using Patient-Generated Subjective Global Assessment tool and hand muscle strength in subjects with pancreatitis.

Pancreatitis patients are at an increased risk of malnutrition due to impaired digestion, absorption, and metabolism. The degree of malnutrition is dependent on the duration, viz. acute or chronic. Studies on nutritional status in patients with pancreatitis are limited. Prevalence of nutritional status, physical functioning, and muscle strength among the subjects are scarce globally. The main aim of this study was to screen the status of malnutrition using appropriate screening tools and to assess hand muscle strength among subjects. A cross-sectional study was conducted on 64 subjects (18-80 years old, 59 males and 5 females) in Mysore city, Karnataka. The patients were screened for malnutrition using a standard tool Patient-Generated Subjective Global Assessment (PG-SGA) and handgrip strength on both dominant and nondominant hands. The majority of patients (n = 44) were categorized as moderately malnourished/suspected malnutrition (Stage B) according to PG-SGA.A significant difference (p < 0.005) in handgrip strength was seen inmen aged 31-40 (t = -3.287)and 41-50 (t = -5.487) years compared tohealthy adults. This study was able to identify patients at risk of malnutrition when thePG-SGA tool was used along with handgrip strength and other anthropometric parameters.

Defining the rate of nutritional and metabolic derangements after pancreatic resection

Background and aimsPancreatic resection is associated with pancreatic exocrine insufficiency (PEI) leading to nutritional consequences. The Pancreatic Nutrition Clinic was established to diagnose and manage PEI through standardised nutritional assessment. In this prospective observational study, we aimed to define the rate of PEI, diabetes mellitus and nutritional abnormalities in patients who underwent pancreatic resection. MethodsAll Pancreatic Nutrition Clinic patients were included for analysis. Clinical data were prospectively obtained at initial assessment. Biochemical data included micronutrient levels, faecal elastase-1 and haemoglobin A1c. Bone mineral density and nutritional assessment were undertaken. ResultsNinety-eight patients were included. Fifty-nine per cent (58/98) had undergone a pancreatoduodenectomy. Ninety-three patients had a faecal elastase-1 result, 65% (60/93) of which had a faecal elastase-1 less than 200 μg/g of faeces. Seventy-five patients (76%) of the total population required PERT, and thirty-nine (40%) were classified as malnourished using the patient-generated subjective global assessment tool. Seventy-two per cent (70/97) had a biochemical deficiency of one or more micronutrients. Thirty-eight people (39%) had diabetes mellitus. Of the seventy-eight patients with a bone mineral density scan available for analysis, 29% (23/78) had osteoporosis and 49% (38/78) osteopenia. ConclusionsPancreatic exocrine insufficiency, micronutrient deficiency, bone disease, diabetes mellitus and malnutrition are highly prevalent in patients who have undergone pancreatic resection.

Agreement between GLIM and PG-SGA for diagnosis of malnutrition depends on the screening tool used in GLIM

The Global Leadership Initiative on Malnutrition (GLIM) has suggested a process for the diagnosis of malnutrition. The process consists of applying an existing screening tool for malnutrition screening, followed by malnutrition diagnostics, and finally categorization of malnutrition severity (moderate or severe) according to specific GLIM criteria. However, it is not known how well the GLIM process agrees with other diagnostic tools used in the current clinical practice. The aim of this study was to validate the GLIM process against the Patient Generated-Subjective Global Assessment (PG-SGA) when different screening tools were applied in the screening step of the GLIM process. Colorectal cancer (CRC) patients from the ongoing CRC-NORDIET study were included. For the GLIM process, the patients were first screened for malnutrition using either 1) Nutritional risk screening, first 4 questions (NRS-2002-4Q), 2) Malnutrition Screening Tool (MST), 3) Malnutrition Universal Screening Tool (MUST) or 4) the PG-SGA short form (PG-SGA-SF). The GLIM malnutrition diagnosis was then based on combining the result from each of the screening methods with the etiological and phenotypic GLIM-criteria including weight loss, BMI and fat free mass. In parallel, the patients were diagnosed using the PG-SGA methodology categorizing the patients into either A: well nourished, B: moderately malnourished or C: severely malnourished. The four different GLIM based diagnoses were then validated against the diagnosis obtained by the PG-SGA tool. Sensitivity, specificity and positive predictive value (PPV) were calculated to evaluate validity. In total, 426 patients were included (mean age: 66, ±8 years) at a mean time of 166 (±56) days after surgery. The GLIM diagnosis based on the four different screening tools identified 10-24% of the patients to be malnourished, of which 3-8% were severely malnourished. The PG-SGA method categorized 15% as moderately malnourished (PG-SGA: category B) and no patients as severely malnourished (PG-SGA: category C). The agreement between the PG-SGA and GLIM process was in general low, but differed according to the tools: PG-SGA SF (sensitivity 47%, PPV 71%), MST (sensitivity 56%, PPV 47%), NRS-2002-4Q (sensitivity 63%, PPV 53%) and MUST (sensitivity 53%, PPV 34%). In this cross-sectional study of patients with CRC, the concordance between the GLIM-criteria and PG-SGA depended on the screening tool used in the GLIM process. Malnutrition frequency based on the GLIM process schould be reported with and without the use of a screening tool.

Postoperative Changes in Nutritional and Functional Status of Gastroesophageal Cancer Patients

Objective Disease-related malnutrition is a debilitating condition frequently observed in patients with cancer. The aim of the current study was to prospectively examine postoperative changes in nutritional and functional status of patients undergoing surgery for gastric, esophageal, and gastroesophageal junction cancer. Methods Participants were prospectively recruited from September 2015 to September 2019. The assessment of malnutrition was based on the Patient-Generated Subjective Global Assessment tool. The functional assessment included the evaluation of muscle strength and physical performance, while muscle mass assessment was based on Skeletal Muscle Mass Index (SMI) derived from the analysis of computed tomography scans. The follow up of patients was scheduled at six months postoperatively. Results A total of 98 patients were analyzed. Mean patient age was 60.79 ± 10.19 years and 80.6% were males. The mean unintentional weight loss at 6 months was 11.7 ± 8.0%. Patients who underwent McKeown esophagectomy reported the greatest weight loss postoperatively (16.2 ± 9.6%), whereas the lowest rate of weight loss was observed in patients who underwent partial gastrectomy (5.6 ± 6.7%). The rate of severe malnutrition declined at six months postoperatively (39.7% vs 27%). Muscle strength and physical performance were significantly deteriorated at 6 months postoperatively, except for the group of partial gastrectomy, while SMI significantly decreased in all groups of patients except for McKewon esophagectomy group. Finally, the prevalence of low muscle mass increased significantly from 43.5% in the preoperative period to 66.7% at the follow-up. Conclusions Our study revealed a significant deterioration in gastroesophageal cancer patient nutritional and functional status at six months postoperatively. The high prevalence of malnutrition and low muscle mass requires systematic follow-up and multidirectional monitoring in order to ensure the successful rehabilitation of these patients.

Comprehensive assessment of nutritional status and nutritional-related complications in newly diagnosed esophageal cancer patients: A cross-sectional study

Malnutrition is prevalent in upper gastrointestinal cancer patients. The purpose of this study was a comprehensive assessment of nutritional status in newly diagnosed patients with esophageal cancer. Newly diagnosed esophageal cancer patients were referred to a chemo-radiation referral center in Mashhad, Iran, between February 2017 to February 2019. Anthropometric indices, a Patient-Generated Subjective Global Assessment (PG-SGA) tool, body composition, dietary intake, nutritional-related complications, and laboratory tests were assessed. One hundred and eighty-nine patients with a mean age of 67.1±12 and a male to female ratio of 98 to 91 were included. Ninety-seven (51.3%) of patients had experienced significant weight loss and 56 (29.6%) were underweight at diagnosis. According to PG-SGA, 179 (94.7%) needed nutritional interventions. Reduced muscle mass and low handgrip strength were observed in 70 (39.4%) and 26 (14.4%) of patients, respectively. Inadequate intakes of energy (less than 24kcal/kg/day) and protein (less than 1.2g/kg/day) were found in 146 (77.8%) and 171 (91%) patients, respectively. The mean total daily energy and protein intakes of subjects were 943.8±540kcal/day, and 30.6±21g/day, respectively. The most common nutritional-related complications were as follows: dysphagia (84.8%), anorexia (31.6%), constipation (62.1%), esophageal pain (48.4%), and dyspepsia (41.1%). Our study demonstrated a high prevalence of malnutrition in newly diagnosed esophageal cancer patients. This fact demonstrates the importance of early screening of nutritional status via PG-SGA tool, clinical evaluation, dietary intake evaluations, and laboratory tests, based on which effective nutritional interventions and Symptoms management may be introduced in these patients.

Nutrition therapy for the management of cancer-related fatigue and quality of life: a systematic review and meta-analysis.

Cancer-related fatigue (CRF) is one of the most commonly reported disease- and treatment-related side effects that impede quality of life. This systematic review and meta-analysis describes the effects of nutrition therapy on CRF and quality of life in people with cancer and cancer survivors. Studies were identified from four electronic databases until September 2017. Eligibility criteria included randomised trials in cancer patients and survivors; any structured dietary intervention describing quantities, proportions, varieties and frequencies of food groups or energy and macronutrient consumption targets; and measures of CRF and quality of life. Standardised mean differences (SMD) were pooled using random-effects models. The American Dietetic Association's Evidence Analysis Library Quality Checklist for Primary Research was used to evaluate the methodological quality and risk of bias. A total of sixteen papers, of fifteen interventions, were included, comprising 1290 participants. Nutrition therapy offered no definitive effect on CRF (SMD 0·18 (95 % CI -0·02, 0·39)) or quality of life (SMD 0·07 (95 % CI -0·10, 0·24)). Preliminary evidence indicates plant-based dietary pattern nutrition therapy may benefit CRF (SMD 0·62 (95 % CI 0·10, 1·15)). Interventions using the patient-generated subjective global assessment tool and prescribing hypermetabolic energy and protein requirements may improve quality of life. However, the heterogeneity seen in study design, nutrition therapies, quality-of-life measures and cancer types impede definitive dietary recommendations to improve quality of life for cancer patients. There is insufficient evidence to determine the optimal nutrition care plan to improve CRF and/or quality of life in cancer patients and survivors.

Nutritional Status of Patients with Cancer: A Prospective Cohort Study of 1,588 Hospitalized Patients

Background: We aimed to assess the nutritional status of cancer patients according to site or treatment type.Methods: We prospectively evaluated the nutritional status of 1,588 patients based on cancer site and treatment type using the Patient-Generated Subjective Global Assessment tool. We also investigated length of stay (LOS), complication rates after surgery and quality of life (QoL).Results: The patients with esophageal, pancreaticobiliary, and lung cancer had higher malnutrition rates than those with stomach, liver, and colon cancer (52.9%, 47.6%, and 42.8% vs. 29.1%, 24.7%, and 15.9%, respectively; P < 0.05). Patients undergoing chemoradiotherapy (CRT) or supportive care had higher malnutrition rates than those undergoing surgery (35.2% or 68.6% vs. 12.3%; P < 0.05). Among patients undergoing surgery, malnourished patients had longer LOS and tended to have more complications than well-nourished patients (P < 0.05 and P = 0.146, respectively). Malnourished patients had also poorer QoL than well-nourished patients (P < 0.05).Conclusion: Malnutrition complicated more in patients with esophageal, pancreaticobiliary, or lung cancer than in those with stomach, liver, or colon cancer. Patients undergoing CRT or supportive care are more likely to be malnourished than those undergoing surgery. Malnutrition may increase LOS and impair QoL.

Validation of assessment categories of the patient-generated subjective global assessment tool in classifying the nutritional status of cancer patients

Background: The patient-generated-subjective global assessment (PG-SGA) tool is considered as the most appropriate nutrition screening tool in oncological setting, since the scoring system enables the patients to be triaged for nutrition intervention. In this study, an attempt was made to determine the precision in classifying patients with cancer as per the Subjective global assessment (SGA) rating or Nutritional Triage recommendations using the PG-SGA tool. Methods: The study was conducted in cancer hospitals of Mysore, Karnataka, India, to recruit 136 cancer patients receiving treatment during a period of 1 year. The PG-SGA tool version 3.22.15 was used for eliciting information and to assess the nutritional status of cancer patients. Results: Among 136 cancer patients, 95.74%, 97.05%, and 74.54% of head-and-neck cancers (HNC), gastrointestinal cancers (GIC), and other cancers (OC), respectively, were malnourished (SGA B + C) according to the SGA categories (SGAC), whereas 93.61%, 97.05%, and 81.81% of HNC, GIC, and OC, respectively, were categorized under severe nutrition risk as per the scored nutritional triage recommendations (SNTR). SGAC had an area under curve (AUC) of 0.961, whereas nutritional triage recommendations had an AUC of 1.0, signifying higher precision of using SNTR to assess the nutritional risk and need for nutritional intervention among cancer patients. Conclusions: Overall, SNTR is more precise in assessing the nutritional status among cancer patients than SGAC and also helps in developing a better nutritional care plan for effective prognosis.

Nutritional status of cancer outpatients using scored patient generated subjective global assessment in two cancer treatment centers, Nairobi, Kenya

BackgroundMalnutrition is a universal problem in cancer patients renowned as an important factor for increased morbidity, decreased quality of life and high mortality. Early diagnosis of malnutrition risk through nutrition screening followed by comprehensive and timely interventions reduces mortality associated with malnutrition. The Scored Patient-Generated Subjective Global Assessment (PGSGA) method has been proved efficient in identifying cancer patients with nutrition challenges and guiding appropriate interventions. However this tool has not been adopted in management of cancer patients in Kenya. The aim of the study was to assess and describe nutrition status of cancer outpatients receiving treatment at Kenyatta National Hospital Hospital (KNH) and Texas Cancer Centre (TCC).MethodsThe study adopted a hospital based descriptive cross sectional study. Cancer outpatients with confirmed stage 1–4 cancers, physically stable, aged 18 years and above and receiving cancer treatment were recruited and assessed using Scored PGSGA tool. Proportions, measures of central tendency and pearsons’ chi-square test were used in statistical analysis.ResultsAmong the 471 participants assessed, 71.8% were female and 28.2% male. Most participants had stage 2, 3 and 4 cancers at 27.2%, 27.2% and 24.3% respectively. Highest proportion of participants had breast (29.7%) and female genital cancers (22.9%). Sixty nine percent of participants were well nourished (SGA-A), 19.7% moderately malnourished (SGA-B) and 11.3% severely malnourished (SGA-C) and this difference was statistically significant. The mean PGSGA score was 6.76 (SD 5.17). Based on the score, 33.8% of participants required critical nutrition care, 34.8% symptoms management, 14.2% constant nutrition education and pharmacological intervention while 17.2% required routine assessments and reassurance. More (m;54.7%, f; 45.3%) males than females were severely malnourished(SGA-C) and this was statistically significant (P < 0.001).Prevalence of severe malnutrition was highest among participants with digestive organ cancers (49.1%) followed by those with lip cancer (17%) and the least prevalence reported in those with Karposi Sarcoma (0%). Most of stage 4 participants were moderately (37.5%) and severely (29.4%) malnourished.ConclusionsThe Scored Patient-Generated Subjective Global Assessment is able to identify cancer patients both at risk of malnutrition and those severely malnourished. It also provides a guideline on the appropriate nutrition intervention hence an important tool in nutrition management of cancer patients.

Comparison of different methods for nutrition assessment in patients with tumors.

Nutrition screening to identify patients at risk of malnutrition is vital for cancer patients because of the high prevalence of malnutrition in this population. The aim of the present study was to compare different methods of nutrition assessment in patients with tumors. From June 2013 to June 2014, we conducted an observational multicenter study to compare the assessment of nutritional status in patients with tumors by anthropometry, biochemical indicators, nutritional risk screening (NRS-2002) and patient-generated subjective global assessment (PG-SGA). Mann-Whitney test and Kruskal-Wallis H non-parametric test were used for intergroup comparisons. Spearmans rank correlation coefficients were calculated to evaluate the association between different methods of nutritional assessment. The κ statistic was used to evaluate the agreement between two assessment methods. A total of 927 oncology inpatients underwent full nutritional assessment and nutrition screening. The PG-SGA tool determined that 13.7% of patients were well-nourished (PG-SGA from 0–1) and the rest (86.3%) were malnourished. Among the malnourished patients, 57.8% were moderately malnourished (PG-SGA from 2–8) and 28.5% were severely malnourished (PG-SGA ≥9). According to NRS-2002, 30.7% of patients were at nutritional risk (NRS-2002 ≥3). There was a significant positive correlation between PG-SGA scores and NRS-2002 scores in both men and women. Compared to albumin, the PG-SGA had a sensitivity of 93.78% and specificity of 21.80%. In comparison, NRS-2002 had a low sensitivity of 43.13% and relatively higher specificity of 82.16%. In conclusion, the relationship between PG-SGA, NRS-2002 and nutritional status is statistically significant. Compared with NRS-2002, PG-SGA is a suitable screening tool for detecting the risk of malnutrition in patients with cancer.

Malnutrition: The Importance of Identification, Documentation, and Coding in the Acute Care Setting.

Malnutrition is a significant issue in the hospital setting. This cross-sectional, observational study determined the prevalence of malnutrition amongst 189 adult inpatients in a teaching hospital using the Patient-Generated Subjective Global Assessment tool and compared data to control groups for coding of malnutrition to determine the estimated unclaimed financial reimbursement associated with this comorbidity. Fifty-three percent of inpatients were classified as malnourished. Significant associations were found between malnutrition and increasing age, decreasing body mass index, and increased length of stay. Ninety-eight percent of malnourished patients were coded as malnourished in medical records. The results of the medical history audit of patients in control groups showed that between 0.9 and 5.4% of patients were coded as malnourished which is remarkably lower than the 52% of patients who were coded as malnourished from the point prevalence study data. This is most likely to be primarily due to lack of identification. The estimated unclaimed annual financial reimbursement due to undiagnosed or undocumented malnutrition based on the point prevalence study was AU$8,536,200. The study found that half the patients were malnourished, with older adults being particularly vulnerable. It is imperative that malnutrition is diagnosed and accurately documented and coded, so appropriate coding, funding reimbursement, and treatment can occur.

Eastern Cooperative Oncology Group score: Agreement between non-small-cell lung cancer patients and their oncologists and clinical implications

Abstract Background Oncologists use Eastern Cooperative Oncology Group (ECOG) performance score to assess patients' performance status (PS) and guide treatment decisions, but patients may not necessarily agree on their scores. We compared PS scores assessed by patients with non-small-cell lung cancer (NSCLC) to those of their medical oncologists to explore concordance and whether any discrepancy may have implications on treatment and survival prediction. Methods NSCLC patients self-assessed their PS scores using the Patient-Generated Subjective Global Assessment tool prior to chemotherapy. Kappa was used to assess agreement of ECOG scores between patients and oncologists. Survival was calculated from date of chemotherapy using Kaplan Meier method. Results A total of 79 patients (median age 63 years, 87% stages IIIB/IV) were included. PS scores differed in 34 (43%) cases. The inter-rater reliability between patients and their oncologists was Kappa=0.35 ( p 0) irrespective of assessor was predictive of survival ( p =0.017–0.023 ) . Conclusions There was only fair agreement in PS scores assessed by NSCLC patients and oncologists, with patient scores usually poorer. A number of patients would have excluded themselves from therapeutic interventions including clinical trials based on their PS rating.

Implementation of the Nutrition Care Process and International Dietetics and Nutrition Terminology in a Single-Center Hemodialysis Unit: Comparing Paper vs Electronic Records

There is little doubt surrounding the benefits of the Nutrition Care Process and International Dietetics and Nutrition Terminology (IDNT) to dietetics practice; however, evidence to support the most efficient method of incorporating these into practice is lacking. The main objective of our study was to compare the efficiency and effectiveness of an electronic and a manual paper-based system for capturing the Nutrition Care Process and IDNT in a single in-center hemodialysis unit. A cohort of 56 adult patients receiving maintenance hemodialysis were followed for 12 months. During the first 6 months, patients received the usual standard care, with documentation via a manual paper-based system. During the following 6-month period (Months 7 to 12), nutrition care was documented by an electronic system. Workload efficiency, number of IDNT codes used related to nutrition-related diagnoses, interventions, monitoring and evaluation using IDNT, nutritional status using the scored Patient-Generated Subjective Global Assessment Tool of Quality of Life were the main outcome measures. Compared with paper-based documentation of nutrition care, our study demonstrated that an electronic system improved the efficiency of total time spent by the dietitian by 13 minutes per consultation. There were also a greater number of nutrition-related diagnoses resolved using the electronic system compared with the paper-based documentation (P<0.001). In conclusion, the implementation of an electronic system compared with a paper-based system in a population receiving hemodialysis resulted in significant improvements in the efficiency of nutrition care and effectiveness related to patient outcomes.

Use of an Abridged Scored Patient-Generated Subjective Global Assessment (abPG-SGA) as a Nutritional Screening Tool for Cancer Patients in an Outpatient Setting

The scored Patient-Generated Subjective Global Assessment tool (PG-SGA), regarded as the most appropriate means of identifying malnutrition in cancer patients, is often challenging to implement in a busy outpatient setting. We assessed the validity of an abridged version of the PG-SGA (abPG-SGA), which forgoes the physical examination, and compared its usefulness in discerning malnutrition to the full PG-SGA and Malnutrition Screening Tool (MST). The nutritional status of 90 oncology outpatients receiving chemotherapy was assessed according to SGA global rating, PG-SGA, and MST. Receiver operating characteristic (ROC) curves were generated to estimate the sensitivity and specificity of various cut-off scores for malnutrition. Thirty-six percent of patients were malnourished (SGA). The abPG-SGA yielded 94% sensitivity and 78% specificity and area under the curve (AUC) = 0.956, which was slightly lower than PG-SGA (97% sensitivity, 86% specificity, AUC = 0.967) and higher than MST (81% sensitivity, 72% specificity, AUC = 0.823). Patient reported symptoms included loss of appetite (30%), altered taste (31%), fatigue (30%), and decreased ability to perform activities of daily living (53%). In conclusion, the abPG-SGA is a practical, informative and valid tool for detecting malnutrition in the outpatient oncology setting.

1544O - Comparison of Nutritional Assessment with a New Definition of Cachexia in Determining Outcomes of Advanced Cancer Patients

ABSTRACT Background An international consensus statement providing a definition and diagnostic criteria for cancer cachexia was recently published. This study aimed to compare the relative prognostic utility of this definition with nutritional status as defined by the Patient-Generated Subjective Global Assessment (PG-SGA) tool. Methods A prospective cohort study was conducted in a tertiary hospital where chemotherapy naive patients with life expectancy ≥3 months were recruited by medical oncologists and a research dietitian. Kaplan-Meier survival analyses were used to determine the median survival of patients with advanced cancer in the cohort study, and a subset of patients who met the criteria for cancer cachexia as defined in the international consensus (Fearon 2011). The log rank chi-square test was used to evaluate the strength of predictors of overall survival (OS). A P value of Results The following table demonstrates the patient baseline characteristics of the two cohorts.Unlabelled TableCachexia (Met ≥1 criteria)Malnourished (PG-SGA B/C)Sample size80% (n= 62/78)58% (n= 66/114)Age, years, mean61 (SD 8.7)63 (SD 9.7)Male, % (n)63% (39)67% (44)% of weight loss in 6 months preceding, mean11.1 (SD 5.5)9.5 (SD 6.4)Estimated OS, mths, median (95% CI) Log rank test (Mantel-Cox)11.4 (5.5 – 17.3) 2.248.4 (4.06 – 12.69) 8.07 Sixty eight percent of the advanced cancer patients (53 of the 78) were both malnourished and met ≥1 of the proposed diagnostic criteria for cachexia at baseline. The log rank test from the Kaplan-Meier survival analysis demonstrated that nutritional status as defined by PG-SGA tool was a stronger overall predictor of OS than the recently defined criteria. Conclusions The concept of using the PG-SGA tool to identify potential patients with cachexia for future trials deserves further investigation given that malnutrition, as determined using this tool, had a better overall predictive value of cancer patients' survival than the proposed diagnostic criteria for cachexia.

Audit of symptoms and prescribing in patients with the anorexia–cachexia syndrome

To audit the profile of symptoms related to the anorexia-cachexia syndrome (ACS) in patients with cancer, and current prescribed medication. Cancer patients within both primary and secondary care in north Durham. Patients with cancer and symptoms of ACS were referred to the specialist pharmacist. Symptom profile was assessed using the Patient Generated Subjective Global Assessment (PG-SGA) tool and current drug history was recorded. Changes to prescribed medication recommended by the specialist pharmacist were communicated to the responsible clinician. Management strategies were standardised according to the evidence base or best practice in the absence of evidence. Quantified symptom burden and analysis of patterns of prescribing in this cohort of patients. Twenty-three out of thirty-two patients referred were well enough for assessment. Hundred and nineteen active symptoms were identified by the PG-SGA tool in those 23 patients. Patients were prescribed a median of eight drugs, excluding nutritional supplements. Side effects of prescribed medication may have been contributory factors to dry mouth and constipation, reported by 21 (91%) and 12 (52%) patients respectively. Many active symptoms were not managed by prescribed medication, most commonly dry mouth, anorexia and early satiety. Eighty-nine recommended changes to prescribed medication were made by the specialist pharmacist, most frequently treatment of dry mouth and prescription of prokinetic antiemetics. ACS in patients with cancer is associated with a significant number of active symptoms, many unmanaged by prescription medication. The potential for standardised assessment and management is raised.
