Use of subjective global assessment and clinical outcomes in critically ill geriatric patients receiving nutrition support

The objective of this study is to examine the prevalence of malnutrition and evaluate the nutrition status and clinical outcome in hospitalized patients aged 65 years and older receiving enteral‐parenteral nutrition. This retrospective study was carried out at Ba?kent University Hospital, Adana, Turkey. A total of 119 patients older than 65 years were recruited. Patients were classified into 3 groups: protein‐energy malnutrition (PEM), moderate PEM, and well nourished according to subjective global assessment (SGA) at admission. All patients were fed by enteral or parenteral route. Acute physiological and chronic health evaluation (APACHE‐2) and simplified acute physiology (SAPS 2) scores were recorded in patients followed in the intensive care unit (ICU). Nutrition status was assessed with biochemical (serum albumin, serum prealbumin) parameters. These results were compared with mortality rate and length of hospital stay (LOS). The subjects' mean (±SD) age was 73.1 ± 5.4 years. Using SGA, 5.9% (n = 7) of the patients were classified as severely PEM, 27.7% (n = 33) were classified as moderately PEM, and 66.4% (n = 79) were classified as well nourished. Some 73.1% (n = 87) of the patients were followed in the ICU. Among all patients, 42.9% (n = 51) were fed by a combined enteral‐parenteral route, 31.1% (n = 37) by an enteral route, 18.5% (n = 22) by a parenteral route, and 7.6% (n = 9) by an oral route. The average length of stay for the patients was 18.9 ± 13.7 days. The mortality rate was 44.5% (n = 53). The mortality rate was 43% (n = 34) in well‐nourished patients (n = 79), 48.5% (n = 16) in moderately PEM patients (n = 33), and 42.9% (n = 3) in severely PEM patients (n = 7) (P = .86). The authors observed no difference between well‐nourished and malnourished patients with regard to the serum protein values on admission, LOS, and mortality rate. In this study, malnutrition as defined by SGA did not influence the mortality rate of critically ill geriatric patients receiving enteral or parenteral nutrition. Furthermore, no factor was found to be a good predictor of survival.     

Nutritional screening in a cancer prehabilitation programme: A cohort study

Background

Cancer patients are often malnourished pre-operatively. The present study aimed to establish whether current screening was appropriate for use in prehabilitation and investigate any association between nutritional risk, functionality and quality of life (QoL).

Methods

This cohort study used routinely collected data from September 2020 to August 2021 from patients in a Prehab4cancer programme. Included patients were aged ≥ 18 years, had colorectal, lung or oesophago-gastric cancer and were scheduled for surgery. Nutritional assessment included Patient-Generated Subjective Global Assessment (PG-SGA) Short-Form and QoL with a sit-to-stand test. Association between nutritional risk and outcomes was analysed using adjusted logistic regression.

Results

From 928 patients referred to Prehab4Cancer service over 12 months, data on nutritional risk were collected from 526 patients. Pre-operatively, 233 out of 526 (44%) patients were at nutritional risk (score ≥ 2). During prehabilitation, 31% of patients improved their PG-SGA and 74% of patients maintained or improved their weight. Odds ratios (OR) with confidence intervals (CI) showed that patients with better QoL using EuroQol-5 Dimensions (OR = 0.05, 95% CI = 0.01, 0.45, p = 0.01), EuroQol Visual Analogue Scale (OR = 0.96, 95% CI = 0.93, 1.00, p = 0.04) or sit-to-stand (OR = 0.96, 95% 0.93, 1.00, p = 0.04) were less likely to be nutritional at risk.

Conclusions

Almost half of patients in Prehab4Cancer programme assessed using PG-SGA were at risk of malnutrition. However, almost half of the sample did not have their risk assessed. Patients at risk of malnutrition were more likely to have a poorer QoL and sit-to-stand test than those who were not at risk.

     

The facilitated early enteral and dietary management effectiveness trial in hospitalized patients with malnutrition

Background: The prevalence of malnutrition in the hospitalized setting is 30% to 55%. Previous studies reported an association of malnutrition with an increased hospital length of stay (LOS), morbidity, and mortality of patients. This study evaluated the role of early nutrition intervention on LOS, diagnosis coding of malnutrition cases, calculating case mix index, and reducing delays in implementing nutrition support to patients. Methods: Demographic data, anthropometric measurements, LOS, and serum albumin levels were collected from 400 patients in 2 medical wards to determine the prevalence of malnutrition and potential delays in nutrition consultation. Based on these results, a nutrition intervention study was conducted in 1 ward; the other ward served as a control. Patients were classified as normally nourished or malnourished. Multivariate general linear regressions were used to reveal the impact of intervention on the change in LOS, controlling for other potential confounding factors on the cohort and a subset with severe malnutrition. Results: Of the 400 patients assessed, 53% had malnutrition. Multiple general linear regressions showed that nutrition intervention reduced LOS an average of 1.93 days in the cohort group and 3.2 days in the severe malnourished group. Case mix index and female gender were positively associated with LOS in the malnourished group. Nutrition intervention reduced the delays in implementing nutrition support to patients by 47%. Conclusions: Results highlight the positive impact of nutrition intervention in terms of reduced LOS in malnourished hospital patients. Reduction in LOS with diagnosis coding of malnutrition cases yielded substantial economic benefits.     

Malnutrition Identified by the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition Consensus Criteria and Other Bedside Tools Is Highly Prevalent in a Sample of Individuals Undergoing Treatment for Head and Neck Cancer

Background: Using the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition (Academy/ASPEN) Consensus malnutrition definition, we estimated malnutrition prevalence in a sample of individuals with head and neck cancer (HNC) and compared it with the Patient‐Generated Subjective Global Assessment (PG‐SGA). We also investigated the utility of the 50‐kHz phase angle (PA) and 200‐kHz/5‐kHz impedance ratio (IR) to identify malnutrition. Materials and Methods: Nineteen individuals (18 males, 1 female) scheduled to undergo chemoradiotherapy were seen at 5 time points during and up to 3 months after treatment completion. Multiple‐frequency bioelectrical impedance analysis, PG‐SGA, nutrition‐focused physical examination, anthropometry, dietary intake, and handgrip strength data were collected. Results: Using the Consensus, 67% were found to be malnourished before treatment initiation; these criteria diagnosed malnutrition with overall good sensitivity (94%) and moderate specificity (43%) compared with PG‐SGA. Over all pooled observations, “malnourished” (by Consensus but not PG‐SGA category) had a lower mean PA (5.2 vs 5.9; P = .03) and higher IR (0.82 vs 0.79; P = .03) than “well‐nourished” categorizations, although the clinical relevance of these findings is unclear. PA and IR were correlated with higher PG‐SGA score (r = ?0.35, r = 0.36; P < .01) and handgrip strength (r = 0.48, r = ?0.47; P < .01). Conclusion: The Academy/ASPEN Consensus and the PG‐SGA were in good agreement. It is unclear whether PA and IR can be used as surrogate markers of nutrition status or muscle loss.     

Malnutrition identification,diagnosis and dietetic referrals: Are we doing a good enough job?

Aim: To determine the prevalence and diagnosis, documentation and referral rates for malnutrition among hospitalised patients and to ascertain potential shortfalls in financial reimbursement to a hospital as a result of malnutrition misdiagnosis. Methods: The Subjective Global Assessment tool was used to assess the nutritional status of 275 randomly selected inpatients on admission over a five‐week period across the acute care wards of a metropolitan tertiary teaching hospital. A retrospective audit of malnourished patients' medical histories was performed to assess diagnosis, documentation and dietetic referral rates for malnutrition. Where malnutrition was not included in the coding of an admission, that admission was hypothetically recoded to determine whether it changed the Diagnosis Related Group and subsequently the payment allocated for that admission. Results: Prevalence of malnutrition was 23%. Malnourished patients had significantly longer lengths of stay by 4.5 days compared with well‐nourished patients (P < 0.001). Only 15% of malnourished patients were correctly identified and documented as such in the medical histories. A dietitian was involved in 45% of malnutrition cases, but only documented 29% of such cases as malnourished. Forty‐eight of 53 (91%) audited cases did not have the corresponding malnutrition code included in their Diagnosis Related Group, resulting in a shortfall of AU$27 617 to the hospital in reimbursements, and AU$1 850 540 when extrapolated across the financial year. Conclusion: Malnutrition is highly prevalent in the acute hospital setting, yet remains poorly identified and formally documented. Many patients are not referred for dietetic intervention, thus compromising their clinical outcomes. Poor documentation of malnutrition can further result in financial shortfalls to the hospital.     

Assessing health status and outcomes in a geriatric day hospital

The study objective was to assess the feasibility and usefulness of recommended outcome measures in older people attending a geriatric day hospital for multidisciplinary assessment and rehabilitation. We used the 'Short Form 36' (SF36) questionnaire which had been proposed as a suitable outcome tool for the elderly, as well as standard assessment scales (eg Barthel index). These were administered by interviewers at the start of day hospital attendance and repeated by postal survey three and six months later. Change in overall health status was rated by the clinical team. The study took place in a geriatric day unit based in a support hospital, specialising in assessment and rehabilitation of older people. Participants were older people referred directly from the community, or following an inpatient day, whose assessment indicated a need for multidisciplinary rehabilitation. Stroke and musculo-skeletal disorders were the commonest underlying conditions. There was a high incidence of non-completion on SF36 questions relating to physical and mental function. Subsequent interviews showed that patients found some questions irrelevant. Floor effects were common. In contrast, the standard scales were invariably fully completed. Compared with local population survey data, respondents had low baseline scores on all SF36 dimensions. Differences over time were probably explained by varying methods of administration. In spite of a clinical perception of improved health status during day hospital attendance, both standard and SF36 scores showed overall deterioration. Two conclusions could be drawn from this study. 1. Measures of physical and mental disability and quality of life gave lower results than expected and continued declining over a six month period, even when the clinical team felt that the patient had improved. 2. Administration of SF36 by an interviewer is essential to obtain meaningful results in older people with poor physical health, which should be interpreted with caution. Goal-specific measures may be more useful in this group of patients.     

Nutritional status and length of stay in patients admitted to an Acute Assessment Unit

BACKGROUND: The Redesigning Care initiative at Flinders Medical Centre aimed to improve access to timely, consistent, quality care. This led to the creation of an Acute Assessment Unit (AAU) where all patients are assessed by the Allied Health team on admission. This study aimed to: (i) determine the nutritional status of patients admitted to the AAU using the scored Patient Generated-Subjective Global Assessment (PG-SGA); and (ii) determine the association between nutritional status and length of stay (LOS). METHODS: A prospective, observational study was conducted in 64 patients (mean age 79.9 +/- 11 years, 76% female). Nutritional status was assessed within 48 h of admission and LOS data were collected prospectively. RESULTS: According to PG-SGA global rating, 53% (n = 34) of patients were malnourished. There was a weak association between PG-SGA score and LOS (r = 0.250, P = 0.046). The malnourished patients had a longer LOS by 1 day compared to well-nourished patients, and while this did not reach statistical significance (Z = -0.988, P = 0.323), it has implications for health care costs. LOS overall was short at a median of 4.5 days (range 1-24). CONCLUSIONS: A significant proportion of patients admitted to the AAU is malnourished. There was a trend for these patients to have a longer LOS, indicating a critical need for nutritional management; however LOS as a whole was short. While nutrition support in hospital is useful in reinforcing dietary education, the short LOS emphasized the importance of discharge education and follow-up.     

The New European Society for Clinical Nutrition and Metabolism Definition of Malnutrition: Application for Nutrition Assessment and Prediction of Morbimortality in an Emergency Service

Background : Recently, the European Society for Clinical Nutrition and Metabolism (ESPEN) provided novel consensus criteria for malnutrition diagnosis. This study aimed to evaluate the applicability of this instrument in combination with different nutrition screening tools (1) to identify malnutrition and (2) to predict morbidity and mortality in hospitalized patients. Materials and Methods : Observational prospective study in 750 adults admitted to the emergency service of a tertiary public hospital. Subjective Global Assessment (SGA—reference method) and the new ESPEN criteria were used to assess nutrition status of patients, who were initially screened for nutrition risk using 4 different tools. Outcome measures included length of hospital stay, occurrence of infection, and incidence of death during hospitalization, analyzed by logistic regression. Results : There was a lack of agreement between the SGA and ESPEN definition of malnutrition, regardless of the nutrition screening tool applied previously (κ = ?0.050 to 0.09). However, when Malnutrition Screening Tool and Nutritional Risk Screening–2002 (NRS‐2002) were used as the screening tool, malnourished patients according to ESPEN criteria showed higher probability of infection (relative risk [RR], 1.54; 95% confidence interval [CI], 1.02–2.31 and RR, 2.06; 95% CI, 1.37–3.10, respectively), and when the NRS‐2002 was used, the risk for death was 2.7 times higher (hazard ratio, 2.69; 95% CI, 1.07–6.81) in malnourished patients than in well‐nourished patients. Conclusion : Although the new ESPEN criteria had a poor diagnostic value, it seems to be a prognostic tool among hospitalized patients, especially when used in combination with the NRS‐2002.     

Accuracy and confidence of allied health assistants administering the subjective global assessment on inpatients in a rural setting: a preliminary feasibility study

Aim

Malnutrition has a significant impact on patient outcomes and duration of inpatient stay. However, conducting timely nutrition assessments can be challenging for rural dietitians. A solution could be for allied health assistants (AHAs) to assist with these assessments. The present study aimed to assess the accuracy and confidence of AHAs trained to conduct the subjective global assessment (SGA) compared with dietitians.

Methods

A non‐inferiority study design was adopted. Forty‐five adult inpatients admitted to a rural and remote health service were assessed independently by both a trained AHA and dietitian within 24 hours. The order of assessment was randomised, with the second assessor blind to the outcome of the initial SGA. Levels of agreement were examined using kappa and percent exact agreement (PEA; set a priori at ≥80%). Rater confidence after each assessment was assessed using a 10‐point scale.

Results

Agreement for overall SGA ratings was high (kappa = 0.84; PEA 84.4%). PEA for individual sub‐components of the SGA ranged from 66.4 to 86.7%. Where discrepancies were identified in global SGA ratings, AHAs provided a more severe rating of malnutrition than dietitians. AHAs reported significantly lower confidence than dietitians (t = 4.49, P < 0.001), although mean confidence for both groups was quite high (AHA=7.5, dietitians = 9.0).

Conclusions

Trained AHAs completed the SGA with similar accuracy to dietitians. Using AHAs may help facilitate timely nutrition assessment in rural health services when a dietitian is not physically present. Further investigation is required to determine the benefits of incorporating this extended role into rural and remote health‐care services.     

Cost of prescribed and delivered health services resulting from a comprehensive geriatric assessment tool in New Zealand

The objective of this study was to estimate the health service use and costs resulting from the introduction of the interRAI Minimum Data Set–Home Care (MDS–HC) assessment compared with usual assessment. A randomised controlled trial of elderly people in New Zealand measured the use and cost of prescribed and delivered (4 months post-assessment) health services of 153 participants assessed using the standard [Needs Assessment and Service Co-ordination (NASC)] tool, and 158 participants assessed using the MDS–HC. The results suggest that the MDS–HC resulted in more prescribed personal health and community services, and less disability support services than with NASC. The cost of prescribed services was significantly greater for the MDS–HC (NZ$1840) than the NASC (NZ$1522, P  < 0.001). The cost of delivered services was significantly greater for the MDS–HC (NZ$4809) than the NASC (NZ$2727, P  < 0.001), including higher costs of hospitalizations (NZ$2523 vs. NZ$1112, P  = 0.257). There were pronounced differences among 'low-need' compared with 'high-need' elderly people. These results suggest that the interRai assessment tool resulted in greater cost of prescribed preventive services and less prescribed disability services than the NASC. However, differences in delivered services were driven primarily by differences in hospitalizations. The results highlight the importance of integrating the assessment procedure with the delivery of health services, but suggest that further study is warranted. The results have implications for purchasers of health services for elderly people.
