A quality improvement nutrition screening and intervention program available to Home and Community Care eligible clients

Objective:  To develop and implement a nutrition screening and dietetic referral system for Home and Community Care (HACC) eligible clients.
Design:  Quality improvement project utilising a prospective, observational design.
Setting:  Sixteen Australian organisations caring for HACC eligible clients.
Subjects:  One thousand one hundred and forty-five HACC eligible clients (mean age 76.5 ± 7.2 years) were screened for nutritional risk during 2003–2005.
Interventions:  Nutrition screening was conducted by trained project officers, allied health staff, community care coordinators and nursing staff using a modified version of the malnutrition screening tool (MST). Dietitians performed a nutrition assessment using the scored Patient Generated-Subjective Global Assessment (PG-SGA) and provided individualised nutrition counselling for those identified to be at risk of malnutrition and agreeing to treatment.
Results:  According to the MST, 170 clients (15%) were identified as being at risk of malnutrition. Of these, 75 (44%) agreed to the dietetic referral and PG-SGA assessment, and 57 were subsequently assessed as malnourished (PG-SGA category B or C), suggesting a malnutrition prevalence between 5% and 11%. Of the 34 malnourished clients receiving multiple dietetic reviews (mean 4.1 ± 2.0 per client), 28 improved, with 17 achieving a well-nourished PG-SGA A rating.
Conclusion:  The development and implementation of a nutrition screening and referral system can identify HACC eligible clients who would benefit from services provided by a dietitian. Further research should identify the reasons why some HACC eligible clients are reluctant to be referred to a dietitian.     

Prevalence of malnutrition in adults in Queensland public hospitals and residential aged care facilities

Aim: To determine the prevalence of malnutrition in Queensland public acute and residential aged care facilities, and explore effects of variables associated with malnutrition in these populations. Methods: A multicentre, cross‐sectional audit of a convenience sample of subjects was carried out as part of a larger audit of pressure ulcers in Queensland public acute and residential aged care facilities in 2002 and again in 2003. Dietitians in 20 hospitals and six aged care facilities conducted single‐day nutritional status audits of 2208 acute and 839 aged care subjects using the Subjective Global Assessment, in either or both audits. Subjects excluded were obstetric, same‐day, paediatric and mental health patients. Weighted average proportions of nutritional status categories for acute and residential aged care facilities across the two audits were determined and compared. The effects of gender, age, facility location and medical specialty on malnutrition were determined via logistic regression. Results: A mean of 34.7 ± 4.0% and 31.4 ± 9.5% of acute subjects and a median of 50.0% and 49.2% of residents of aged care facilities were found to be malnourished in Audits 1 and 2, respectively. Variables found to be significantly associated with an increased odds risk of malnutrition included: older age groups, male (in residential aged care facilities), metropolitan location of facility and medical specialty, in particular, oncology and critical care. Conclusion: Malnutrition is significant in public acute and residential aged care facilities in Queensland. Action must be taken to increase the recognition, prevention and treatment of malnutrition especially in high‐risk groups.     

Seven‐Point Subjective Global Assessment Is More Time Sensitive Than Conventional Subjective Global Assessment in Detecting Nutrition Changes

Background: It is important for nutrition intervention in malnourished patients to be guided by accurate evaluation and detection of small changes in the patient's nutrition status over time. However, the current Subjective Global Assessment (SGA) is not able to detect changes in a short period. The aim of the study was to determine whether the 7‐point SGA is more time sensitive to nutrition changes than the conventional SGA. Methods: In this prospective study, 67 adult inpatients assessed as malnourished using both the 7‐point SGA and conventional SGA were recruited. Each patient received nutrition intervention and was followed up after discharge. Patients were reassessed using both tools at 1, 3, and 5 months from baseline assessment. Results: It took significantly shorter time to see a 1‐point change using the 7‐point SGA compared with the conventional SGA (median: 1 month vs 3 months, P = .002). The likelihood of at least a 1‐point change is 6.74 times greater in the 7‐point SGA compared with the conventional SGA after controlling for age, sex, and medical specialties (odds ratio, 6.74; 95% confidence interval, 2.88–15.80; P < .001). Fifty‐six percent of patients who had no change in SGA score had changes detected using the 7‐point SGA. The level of agreement was 100% (κ = 1, P < .001) between the 7‐point SGA and 3‐point SGA and 83% (κ = 0.726, P < .001) between 2 blinded assessors for the 7‐point SGA. Conclusion: The 7‐point SGA is more time sensitive in its response to nutrition changes than the conventional SGA. It can be used to guide nutrition intervention for patients.     

Evaluation of change in dietitians’ perceived comprehensibility and difficulty of the Patient‐Generated Subjective Global Assessment (PG‐SGA) after a single training in the use of the instrument

Background

The Patient‐Generated Subjective Global Assessment (PG‐SGA) is an instrument used to assess malnutrition and its risk factors. Some items of the PG‐SGA may be perceived as hard to comprehend or as difficult by healthcare professionals. The present study aimed to determine whether and how dietitians’ perceptions of comprehensibility and difficulty of the PG‐SGA change after a single training in PG‐SGA use.

Methods

In this prospective evaluation study, Dutch PG‐SGA‐naïve dietitians completed a questionnaire regarding perceived comprehensibility and difficulty of the PG‐SGA before (T0) and after (T1) receiving a single training in the use of the instrument. Perceived comprehensibility and difficulty were operationalised by calculating item and scale indices for comprehensibility (I‐CI, S‐CI) and difficulty (I‐DI, S‐DI) at T0 and T1. An item index of 0.78 was considered acceptable, a scale index of 0.80 was considered acceptable and a scale index of 0.90 was considered excellent.

Results

A total of 35 participants completed the questionnaire both at T0 and T1. All item indices related to comprehensibility and difficulty improved, although I‐DI for the items regarding food intake and physical examination remained below 0.78. Scale indices for difficulty and comprehensibility of the PG‐SGA changed significantly (P < 0.001) from not acceptable at T0 (S‐CI = 0.69; S‐DI = 0.57) to excellent for comprehensibility (S‐CI = 0.95) and acceptable for difficulty (S‐DI = 0.86) at T1.

Conclusions

The findings of the present study suggest that significant improvement in PG‐SGA‐naïve dietitians’ perception of comprehensibility and difficulty of the PG‐SGA can be achieved quickly by providing a 1 day of training in the use of the PG‐SGA.     

The presence of malnutrition in community‐living older adults receiving home nursing services

Aim: To determine the extent of malnutrition and malnutrition risk among community‐living older people (aged 65 years and over) who are receiving care from a metropolitan home nursing service in Victoria, Australia. Method: Over a 3‐month period (May–July 2009), 235 clients aged 65 years and over from a community nursing service providing home nursing care were assessed for malnutrition using the Mini Nutritional Assessment (MNA®, Nestle, Vevey, Switzerland). Results: Thirty‐four per cent (34.5%) of clients were identified as being at risk of malnutrition, while 8.1% were found to be malnourished. There was no significant relationship between nutrition risk and gender, country of birth or living arrangements. Conclusion: Malnutrition and nutrition risk was found to be an issue among this sample of community‐living older adults who were receiving home nursing care in Victoria, Australia. In this study, just over 40% of the participants were either at risk of malnutrition or malnourished, which highlights the vulnerability of this group of older people and the need for routine nutrition screening and a targeted intervention program to address nutrition issues.

Use of the mini nutritional assessment tool in elderly people from long-term institutions of Southeast of Brazil

Background: the Mini Nutritional Assessment (MNA) is a multidimensional method of nutritional evaluation that allows the diagnosis of malnutrition and risk of malnutrition in elderly people, it is important to mention that this method has not been well studied in Brazil.Objective: to verify the use of the MNA in elderly people that has been living in long term institutions for elderly people.Design: transversal study.Participants: 89 people (≥ 60 years), being 64.0% men. The average of age for both genders was 73.7±9.1 years old, being 72.8±8.9 years old for men, and 75.3±9.3 years old for women.Setting: long-term institutions for elderly people located in the Southeast of Brazil.Methods: it was calculated the sensibility, specificity, and positive and negative predictive values. It was data to set up a ROC curve to verify the accuracy of the MNA. The variable used as a “standard” for the nutritional diagnosis of the elderly people was the corrected arm muscle area because it is able to provide information or an estimative of the muscle reserve of a person being considered a good indicator of malnutrition in elderly people.Results: the sensibility was 84.0%, the specificity was 36.0%, the positive predictive value was 77.0%, and the negative predictive value was 47.0%; the area of the ROC curve was 0.71 (71.0%).Conclusion: the MNA method has showed accuracy, and sensibility when dealing with the diagnosis of malnutrition and risk of malnutrition in institutionalized elderly groups of the Southeastern region of Brazil, however, it presented a low specificity.

Evaluation of malnutrition status and related risk factors in geriatric outpatient clinic

BACKGROUND/OBJECTIVESMalnutrition risk and malnutrition among the elderly is a public health concern. In combating this health-related problem, it is critically important to evaluate the risk factors in a multidimensional way and to apply appropriate nutrition intervention based on the results.SUBJECTS/METHODSA cross-sectional study was conducted on 215 elderly patients (32.6% male, 67.4% female) in a geriatric outpatient clinic of a hospital in Turkey. Nutritional questionnaires that incorporated the 24-h recall method were applied to determine general characteristics of patients, their health status, nutritional habits, and daily energy and nutrient intakes. Mini Nutritional Assessment was used to determine nutritional status. Relevant anthropometric measurements were obtained.RESULTSThe subjects'' mean age was 76.1 ± 7.0 years, and the prevalence of malnutrition (n = 7) and risk of malnutrition (n = 53) among the 215 subjects was 3.2% and 24.7%, respectively. Patients with malnutrition or risk of malnutrition were found to be single, have a depression diagnosis, in an older age group, have less appetite, more tooth loss, have more frequent swallowing/chewing difficulty, and have more frequent meal skipping. In addition, mean daily energy, carbohydrate, fat, fiber, vitamin E, vitamin B1, vitamin B2, vitamin B6, vitamin C, folates, potassium, magnesium, phosphorus, iron intake, and water consumption were found to be statistically significantly low in subjects with malnutrition or risk of malnutrition. After performing regression analysis to determine confounding factors, malnutrition risk was significantly associated with marital status, loss of teeth, appetite status, and depression.CONCLUSIONSRoutine nutritional screening and assessment of the elderly should be performed. If nutritional deficiencies cannot be diagnosed early and treated, self-sufficiency in the elderly may deteriorate, resulting in increased institutionalization.     

Combining 2 Commonly Adopted Nutrition Instruments in the Critical Care Setting Is Superior to Administering Either One Alone

Background: This study aimed to determine the agreement between the modified Nutrition Risk in Critically ill Score (mNUTRIC) and the Subjective Global Assessment (SGA) and compare their ability in discriminating and quantifying mortality risk independently and in combination. Methods: Between August 2015 and October 2016, all patients in a Singaporean hospital received the SGA within 48 hours of intensive care unit admission. Nutrition status was dichotomized into presence or absence of malnutrition. The mNUTRIC of patients was retrospectively calculated at the end of the study, and high mNUTRIC was defined as scores ≥5. Results: There were 439 patients and 67.9% had high mNUTRIC, whereas only 28% were malnourished. Hospital mortality was 29.6%, and none was lost to follow‐up. Although both tools had poor agreement (κ statistics: 0.13, P < .001), they had similar discriminative value for hospital mortality (C‐statistics [95% confidence interval (CI)], 0.66 [0.62–0.70] for high mNUTRIC and 0.61 [0.56–0.66] for malnutrition, P = .12). However, a high mNUTRIC was associated with higher adjusted odds for hospital mortality compared with malnutrition (adjusted odds ratio [95% CI], 5.32 [2.15–13.17], P < .001, and 4.27 [1.03–17.71], P = .046, respectively). Combination of both tools showed malnutrition and high mNUTRIC were associated with the highest adjusted odds for hospital mortality (14.43 [5.38–38.78], P < .001). Conclusion: The mNUTRIC and SGA had poor agreement. Although they individually provided a fair discriminative value for hospital mortality, the combination of these approaches is a better discriminator to quantify mortality risk.     

Role of nutrition in liver transplantation for end-stage chronic liver disease

Patients with end-stage liver disease often reveal significant protein-energy malnutrition, which may deteriorate after listing for transplantation. Since malnutrition affects post-transplant survival, precise assessment must be an integral part of pre- and post-surgical management. While there is wide agreement that aggressive treatment of nutritional deficiencies is required, strong scientific evidence supporting nutritional therapy is sparse. In practice, oral nutritional supplements are preferred over parenteral nutrition, but enteral tube feeding may be necessary to maintain adequate calorie intake. Protein restriction should be avoided and administration of branched-chain amino acids may help yield a sufficient protein supply. Specific problems such as micronutrient deficiency, fluid balance, cholestasis, encephalopathy, and comorbid conditions need attention in order to optimize patient outcome.
