Screening for malnutrition in nursing home residents: Comparison of different risk markers and their association to functional impairment

Objectives

To identify nursing home residents with malnutrition or at risk of malnutrition by using different markers, determine if the Mini Nutritional Assessment (MNA®) is able to identify all residents at risk according to single risk markers and explore the relation between risk markers and functional impairment.

Design

Cross-sectional study.

Setting

Six German nursing homes.

Participants

286 residents (86±7y, 89% female).

Measurements

Screening for malnutrition or its risk included low BMI (≤22 kg/m²), recent weight loss (WL), low food intake (LI) as single risk markers and MNA (<24 points, p.) as composite marker. Prevalence of single nutritional risk markers in different MNA categories was compared by cross-tables. Mental (cognition, mood) and physical function (mobility) were assessed by interviewing nursing staff and association of impaired status to nutritional risk markers determined by Chi² test.

Results

32.9% of residents had a low BMI, 11.9% WL and 21.3% LI. 60.2% were categorized malnourished (18.2%) or at risk of malnutrition (42.0%) by MNA. 64% presented at least one of these nutritional risk markers. Of those classified malnourished by MNA, 96.2% also showed low BMI, WL or LI. In contrast, eleven residents (9.6%) considered well-nourished by MNA presented single risk markers (9 low BMI, 2 WL). Cognitive impairment, depressive symptoms and immobility was present in 59.0%, 20.8% and 25.5%, respectively. Functional impairment, and in particular severe impairment, was to a higher proportion present in residents at nutritional risk independent of the chosen marker (MNA<24 p., low BMI, WL, LI).

Conclusion

The high prevalence of nutritional risk highlights the importance of regular screening of nursing home residents. The MNA identified nearly all residents with low BMI, WL and LI. The close association between nutritional risk and functional impairment requires increased awareness for nutritional problems especially in functionally impaired residents, to early initiate nutritional measures and thus, prevent further nutritional and functional deterioration.     

Institutional factors associated with the nutritional status of residents from 10 german nursing homes (ernstes study)

Objectives

In nursing homes malnutrition among residents is widespread. Because residents place part of their personal freedom of choice into institutional hands, institution-specific factors may influence nutritional status of residents.

Design

Multi-centre cross-sectional study.

Setting

10 nation-wide German nursing homes.

Participants

714 exclusively orally fed residents (aged 65 years and older, not in final weeks of life).

Measurements

Participants’ characteristics (e. g. gender, age, level of care, dementia diagnosis), body mass index (BMI), mini nutritional assessment (MNA), energy intake (3-day dietary record, BLS II.3), and selected institution-specific factors (size of institution, daily rate for food supply, number of residents per care staff member). Metric data are given as median (P25, P75).

Results

11 % of residents (81 % female, 85 (81, 91) years) had a BMI <20 kg/m² (n=658). According to MNA, 10 % of the residents were malnourished (n=650). Capacity of institutions was 116 (56, 139) beds, care staff ratio was 4.1 (3.5, 4.2) residents per care person (mean over all care levels), and daily food budget was 4.45 (4.10, 4.71) Euro/d. Low daily food budget was associated with a higher risk for a BMI <20 kg/m² (OR 3.30 [95 %CI 1.70–6.42]). Higher food budget also decreased malnutrition risk (OR 0.66 [0.46–0.95]) according to MNA. Residents’ mean energy intake was 6.1 (5.2, 7.1; n=565) MJ/day in women and 7.1 (6.2, 8.2; n=132) MJ/day in men. Intake was higher with small facility size, higher food budget, and lower care staff ratio (P <0.05).

Conclusion

The institutional environment affects the nutritional status of nursing home residents as an independent risk factor. The results suggest promotion of small facilities and the provision of more care staff and more financial resources for food in the structural design of residential homes.     

The diagnostic accuracy of the revised mini nutritional assessment short form for older people living in the community and in nursing homes

Objective

The aim of this study was to determine the diagnostic accuracy of the CC-SF, which was developed to use calf circumference (CC) instead of BMI in the MNA-SF, for elderly people living in the community and in nursing homes. It also aimed separately to determine the correlation of CC-SF and BMI-SF with the full MNA.

Study Design and Methods

The study included 640 elderly people living in their community and 243 elderly people living in nursing homes. Accuracy was assessed by determining the sensitivity and selectivity of the nutritional assessments. The correlations between the MNA-SFs and the full MNA were analyzed.

Results

The correlation between MNA-SFs and full MNAs was strong, significant and almost identical both in the community and in nursing homes (r=0.86–0.88; p<0.001). The observed agreement between the BMI-SF and the full MNA was 82.2% in the community and 77.8% in the nursing homes. There was a substantial agreement by kappa values in the comparison of community and nursing homes (the Kappa value of the BMI-SF was 0.63 in the community and 0.62 in the nursing homes, and the kappa value of the CC-SF was 0.62 in the community and 0.63 in the nursing homes). When compared to the full MNA the MNA-SFs tended to underestimate nutritional status. Both MNA-SFs had similarly high sensitivity and selectivity, both in the community and nursing homes. (when dichotomized as “malnourished-at risk of malnutrition” versus “well nourished” and “malnourished” versus “at risk of malnutrition-well nourished”) (over 80%).

Conclusion

In cases where BMI cannot be determined, the CC-SF is a good substitute for the BMI-SF.     

Validation of the revised mini nutritional assessment short-forms in nursing homes in Spain

Objective

To contribute to the validation of the revised BMI-MNA-SF and CC- MNA-SF with regard to association and agreement with the full-MNA, considered as gold standard, in nursing homes in Spain.

Design

Prospective analysis.

Setting

Nursing homes.

Participants

Eight hundred ninety five subjects aged 65 or older meeting inclusion criteria.

Measurements

Correlation, diagnostic accuracy and agreement between the revised MNA short forms and the MNA full form.

Results

The MNA-SFs correlated strongly with the full MNA version (Pearson’s correlation coefficient r=0.904; p<0.001). High values of sensitivity, specificity and predictive values were obtained for the BMI- MNA-SF and CC-MNA-SF against the full-MNA when the dichotomized categorizations “malnourished-at risk of malnutrition” vs “well nourished” and “malnourished” vs “at risk of malnutrition-well nourished” were considered (Youden’s index at least 0.695 in all cases). Areas under the ROC curves also reached high values (BMI-SF: 0.950 and CC-SF: 0.923 for the first categorization; BMI-SF: 0.979 and CC-SF: 0.978 for the second one) showing both tests excellent accuracy with the full-MNA. The agreement between the MNA-SFs and the full-MNA was quantified as the percentage of correct classifications. The BMI-MNA-SF classified 83.80% correctly and the CC-MNA-SF classified 78.55% correctly. Significant proportions of subjects were underestimated by both MNA-SFs. Just about 6% of overestimations were found in both cases.

Conclusion

The revised BMI-MNA-SF and CC-MNA-SF are rapid, easy and reliable tools capable to identify malnourished individuals and those who are at risk of malnutrition with minimal misclassifications with potential harm in nursing home residents. Due to the special characteristics of elderly staying in these institutions, the CC-MNA-SF is a good option to replace the BMI-MNA-SF when BMI is not available.     

Screening for malnutrition among nursing home residents — a comparative analysis of the Mini Nutritional Assessment, the Nutritional Risk Screening, and the Malnutrition Universal Screening Tool

Background

The European Society for Clinical Nutrition and Metabolism (ESPEN) has recommended the Mini Nutritional Assessment (MNA®), the Nutritional Risk Screening 2002 (NRS), and the Malnutrition Universal Screening Tool (MUST) for nutritional screening in various settings and age groups. While in recent years all three tools have been applied to nursing home residents, there is still no consensus on the most appropriate screening tool in this specific setting.

Aim

The present study aims at comparing the MNA, the NRS, and the MUST with regard to applicability, categorization of nutritional status, and predictive value in the nursing home setting.

Method

MNA, NRS, and MUST were performed on 200 residents from two municipal nursing homes in Nuremberg, Germany. Follow-up data on infection, hospitalization, and mortality were collected after six and again after twelve months.

Results

Among 200 residents (mean age 85.5 ±7.8 years) the MNA could be completed in 188 (94.0%) and the NRS and MUST in 198 (99.0%) residents. The prevalence of ‘malnutrition’ according to the MNA was 15.4%. The prevalence of ‘risk of malnutrition’ (NRS) and ‘high risk of malnutrition’ (MUST), respectively, was 8.6% for both tools. The individual categorization of nutritional status showed poor agreement between NRS and MUST on the one hand and MNA on the other. For all tools a significant association between nutritional status and mortality was demonstrated during follow-up as classification in ‘malnourished’, respectively ‘high risk of malnutrition’ or ‘nutritional risk’, was significantly associated with increased hazard ratios. However, the MNA showed the best predictive value for survival among well-nourished residents.

Conclusion

The evaluation of nutritional status in nursing home residents by MNA, NRS, and MUST shows significant differences. This observation may be of clinical relevance as nutritional intervention is usually based on screening results. As the items of the MNA reflect particularities of the nursing home population, this tool currently appears to be the most suitable one in this setting.     

Factors associated with deterioration of mini nutritional assessment-short form status of nursing home residents during a 2-year period

Objective

A number of other studies have been conducted to verify the Mini Nutritional Assessment (MNA) or the MNA short form (MNA-SF) as a nutritional assessment/screening tool in various clinical settings or communities. However, there are few longitudinal studies using these tools to analyze which factors affect the incidence of deteriorating nutritional status. We tried to identify the factors associated with deterioration of MNA-SF status of nursing home residents during a 2-year period.

Methods

Participants were 392 people with a mean age of 84.3 in 12 nursing homes in Japan. The factors associated with deterioration in MNA-SF categories during the study period compared to stable/improved MNA-SF categories were identified.

Results

At baseline, 19.9% of the participants were malnourished and 60.2% were at risk of malnutrition, according to the MNA-SF classification. After 2 years, 66.3% participants maintained and 6.1% participants improved their nutritional status according to the MNA-SF classification, while 27.6% showed deterioration in MNA-SF status. Stepwise logistic-regression procedure indicated that basic ADL impairment and hospitalization during the follow-up period were associated with declining MNA-SF status.

Conclusions

Poor basic ADL status and hospitalization during the follow-up period were associated with malnutrition and risk of malnutrition as assessed by MNA-SF of nursing homes residents during a 2-year period.     

Quality of life in nursing homes: results of a qualitative resident survey

Purpose

The growing importance of residential nursing care has been accompanied by an increasing demand for instruments measuring quality of life in nursing homes. Quality of life is a complex construct with both subjective and objective aspects that does not lend itself to being determined by a single measure. The aim of this study was therefore to identify dimensions of life that nursing home residents perceive as having a particular impact on their overall quality of life.

Methods

Data were obtained from 9 men and 33 women from eight nursing homes by means of semi-structured narrative interviews. The interviews were analyzed using the documentary method.

Results

Ten central dimensions of subjective quality of life were derived from the interview data: social contacts, self-determination and autonomy, privacy, peace and quiet, variety of stimuli and activities, feeling at home, security, health, being kept informed, and meaningful/enjoyable activity. Some of these dimensions are multifaceted and have further subdimensions.

Conclusion

The aspects emerging as relevant to residents’ subjective quality of life extend far beyond care- and health-related aspects. Nevertheless, some of the quality of life dimensions reconstructed are within the direct influence of the home (e.g., variety of stimuli and activities or being kept informed) and can possibly be improved by attending to the residents’ objective situation.     

Malnutrition in Turkish nursing homes: A correlate of short term mortality

Objective

Elderly nursing home residents are under high risk of malnutrition. Early interventions to prevent malnutrition may play a critical role in malnutrition-mortality correlation. This study aimed to obtain insight into the prevalence of malnutrition in nursing homes in the capital city of Turkey and the role of malnutrition in predicting the risk for short-term mortality.

Design

This study was conducted in seven different residential care facilities in Ankara.

Measurements

Nutritional status was evaluated by Mini Nutritional Assessment-Short Form.

Results

The mean age of the 534 participants was 79.46±7.22 years. Nutritional assessment revealed that 15.9% of all older adults suffered from malnutrition and another 53.6% were at risk of malnutrition. The mortality rate for all subjects was 118 (22.1%) over 18 months, which was significantly higher in participants with malnutrition.

Conclusions

We noted a high prevalence of malnutrition and a strong correlation of increased mortality with malnutrition in nursing home residents. Given the negative impact of malnutrition on mortality and morbidity, an emphasis should be placed on an effective nutritional policy in nursing homes.     

Validation of the modified mini nutritional assessment short-forms in different populations of older people in Poland

Objective

To assess the usefulness in different populations of elderly people in Poland of both modified versions of Mini Nutritional Assessment Short-Forms (MNA-SFs) with a three-category scoring classification: one using BMI (MNA-SF-BMI) and another using calf circumference (MNA-SF-CC).

Setting and Participants

A group of 932 community-dwelling subjects from the urban environment, 812 subjects from the rural environment and 859 subjects from an institutional environment (nursing homes).

Measurements

Agreement between both MNA-SFs and the MNA full form. Results: MNA-SF-BMI correctly classified 84.12%, 82.51% and 81.84% of subjects from urban, rural and institutional environment, respectively. For MNA-SF-CC those values were 82.4%, 71.8% and 76.6%, respectively. The sensitivity and specificity of MNA-SF-BMI and MNA-SF-CC against full MNA in screening for “at risk/malnutrition” and “malnutrition” were generally very high, except for relatively lower sensitivity (74.1%) when screening for “malnutrition” with MNA-SF-CC in nursing homes.

Conclusion

Both MNA-SFs can be recommended as screening tools in assessing the nutritional state of the community-dwelling and institutionalised elderly in Poland. The full version of the MNA confirmed the results of MNA-SFs in this group. The “classic” MNA-SF using BMI was found to perform better than the MNA-SF-CC. The MNA-SF-CC should be used only when measuring BMI is not possible. While using MNASF-CC in nursing homes, a higher MNA-SF-CC cut-point of eleven should be rather used in this population to screen for “at risk/malnutrition”.     

Cost and care models for acutely ill nursing home residents in Germany: the example of pneumonia

Background

Hospitalisation of acutely ill nursing home residents is associated with health risks such as infections, complications, or falls, and results in high costs for the health care system. Taking the case of pneumonia, nursing homes generally can ensure care according to guidelines.

Aim

Extrapolation of overall expenditures for the German statutory health insurance system from the hospitalisation of nursing home residents with respiratory infection/pneumonia; developing alternative cost scenarios to compare nursing home care with hospital care in consideration of patients’ condition.

Methods

Data provided by health insurance funds were extrapolated to the German statutory health insurance system and weighted via German-DRG case values. Care processes (hospital vs. nursing home) were modelled, and treatment steps were divided into cost categories. The patient’s condition was standardised via the Barthel Index.

Results

Total expenditures of € 163.3 million were incurred for inpatient care of nursing home residents transferred to hospitals for respiratory infection/pneumonia in 2013 in Germany. Process modelling reveals lower direct costs for nursing home care as well as better development of patients’ condition. Looking at operators of nursing homes, both care scenarios necessitate additional services without reimbursement.

Conclusion

Expenditure projections for the hospital care of nursing home residents with pneumonia reveal high saving potential. Avoidance of hospital admission serves to considerably reduce the insurers’ expenditures but also the duration and severity of illness. The study illustrates economic incentive structures for health care providers and indicates courses of action for health policy and nursing homes operators.

     

Patterns of chronic co-morbid medical conditions in older residents of U.S. nursing homes: Differences between the sexes and across the agespan

Objective

There are limited data on combinations of co-morbid conditions to guide efforts to improve therapeutic strategies in patients with multiple co-morbid conditions. To some extent, this may be due to limited data on combinations of co-morbid conditions in patient groups. Our goal was to determine the most common comorbid medical conditions in older residents of U. S. nursing homes and identify sex differences in prevalences and changes across the agespan of nursing residents.

Design

Cross sectional analysis of National Nursing Home Survey (NNHS) —a nationally representative sample with comprehensive medical data on nursing home residents.

Setting

1174 Nursing homes.

Participants

Long term stay residents of U.S. Nursing Homes aged 65 years and older (11,734: 8745 women, 2989 men).

Measurements

Determination of the prevalences of the most frequent two and three disease combinations identified using Clinical Classifications Software (CCS) for ICD-9-CM and a composite vascular disease diagnosis (atherosclerosis and/or coronary artery disease, and/or peripheral arterial disease, and/or cerebrovascular disease or stroke) from the most recent and only NNHS survey with comprehensive medical diagnosis information.

Results

Frequent 2-disease combinations were: hypertension (HTN) + dementia (DEM) in 27%, HTN + any Vascular (Vasc) disease (26%), HTN + depression(DEP) 21%, HTN + arthritis(ARTH) 20%, DEM + Vasc (21%), DEM+Depression 19%, Arthritis + DEM 17%, DEP + Vasc (16%), ARTH + Vasc (15%), followed by HTN + GERD (14%) and ARTH + DEP (14%). Frequent 3-disease combinations: HTN +VASC+ DEP in 13%, HTN +DEM +DEP (11%), and HTN+Arthritis+DEM (10%). HTN was in 80% of the top 3-disease combinations, Vasc in 50%, HTN+VASC in 35%, DEM or DEP in 40%, ARTH in 25% and GERD in 20%. Combinations with anemia, arthritis, dementia, heart failure, osteroporosis, thyroid disease were higher in women, COPD combinations higher in men. As age increased, dementia, depression, arthritis, and anemia with hypertension were common co-morbid combinations, diabetes and heart failure were not.

Conclusions

Hypertension, vascular disease, dementia, arthritis, depression, and gastroesophageal reflux disease were part of the most prevalent co-morbid conditions. Multimorbidity patterns can be identified in nursing home residents and vary with age and by sex.     

Nutritional assessment and follow-up of residents with and without dementia in nursing homes in the Limousin region of France: A health network initiative

Introduction

Limousin in France has the second oldest regional population in Europe, with people over 65-years-old who have Alzheimer??s disease accounting for more than 9%. In France as a whole, a large number of residents in nursing homes (NH) have dementia, leading to many nutritional problems. LINUT is a health network that assesses the nutritional status of elderly NH residents and provides support where necessary. Aims of the present study were to use this network to evaluate the nutritional status of NH residents with and without dementia and to review changes after 4 months of intervention.

Methods

A cross-sectional survey was conducted by a doctor and a dietician at baseline (T0) and 4 months (T4) among residents at the 26 NH in Limousin that agreed to take part. The evaluation criteria included presence of dementia, depression and autonomy, weight, height, body mass index, Mini Nutritional Assessement (MNA?), and a 3-day survey of food intake.

Results

The 346 residents assessed at T0 were aged 87.9±6.9 years, 83.4% were women, 66.8% had dementia, 53.3% were malnourished and 27.4% obese. Autonomy was not affected by obesity. Residents with dementia had a lower Activities of Daily Living score and a lower weight than non-demented individuals (2.2±1.2 vs. 2.7±1.7 p=0.03 and 60.1±16.3 vs. 64.7±20.0 kg p=0.03, respectively), were more often malnourished (56.1% vs. 46.4% p=0.004) and less often obese (22.0% vs. 39.1% p=0.004) but consumed more protein (62.6±17.8 vs. 58.2±16.9 g/d p=0.04, 1.1±0.4 vs. 1.0±0.4 g/kg/d p=0.005). Energy intake was at the lower limit of French recommendations (26.4±8.8 vs. >25.0 kcal/kg/d). Assessment of all residents at T4 showed improved MNA? (+0.4 points/month p=0.02), protein intake (+3.3 g/d p=0.0007), and energy intake (+41.4 kcal/d p=0.01 and 0.1 kcal/kg/d p=0.03). Variations in prevalences of malnutrition and obesity were not statistically significant. MNA? increased in the dementia group (+0.29±0.8 points/month p=0.003). All other changes were comparable, and nutritional status did not differ more between the two groups at T4 than at T0.

Conclusion

The prevalence of dementia was high in the population studied. Malnutrition was the main problem, particularly if residents had dementia. Protein intake was satisfactory, but energy intake often insufficient. The nutritional status of dementia patients improved after 4 months of follow-up, suggesting that effective action to support such services would be worthwhile.     

Psychohygiene in der ?Palliative Care“

Background

The mental strain for nursing staff in palliative care has been sufficiently described in recent years. However, in a nursing home, employees from other professional guilds are also active in the same context and often have intensive contact with the residents as well as with their relatives. It could already be shown that their mental strain does not differ from those of the nursing staff in several constructs. However, the special demands of palliative care were not considered in the past studies.

Aims

The present study tries to assess the effects of palliative settings on mental hygiene and compare nursing to non-nursing staff.

Methods

In the nursing home Mattenhof-Irchelpark, which belongs to the City of Zurich Nursing Homes, an enquiry by questionnaires was carried out among nursing and non-nursing staff. A total of 72 employees participated in this study. We examined the constructs ??contact with relatives?? and ??mental hygiene?? with a 7-point Likert scale.

Results

Employees from non-nursing divisions estimated their competence in ??contact with relatives?? to be significantly lower (p=0.005) and they felt equally burdened as the nursing staff. Analysis of the scale ??mental hygiene?? yielded significantly higher values of stress for the non-nursing staff in comparison to the nursing staff (p=0.022).

Conclusion

In summary, it can be stated that not only the nursing staff feels confronted with psychic challenges in the context of palliative care. Also employees from non-nursing areas perceive these challenges at least equally.     

Ambulante Versorgung Pflegebed��rftiger bei Unwetter

Background

Adaptation to demographic change and climate change includes ensuring nursing care at home even in the case of thunderstorms. The sensibility of nursing agencies, their current strategies and needs for action were of interest.

Methods

We performed 24 semi-structured interviews and 4 focus group sessions with staff of nursing agencies and local authorities (N=43). Data analysis followed the grounded theory approach.

Results

Despite some experiences, the awareness of the problem is rather low. Action in case of emergency is spontaneous, and emergency plans do not exist. A plan for action was developed and chances for implementation assessed by experts.

Discussion

Implementation of the action plan will gain further experience.

Conclusions

Sensitising and qualifying nursing staff seems necessary and practicable. Structural problems still need solutions.     

Dentition status,malnutrition and mortality among older service housing residents

Background

Oral health status and oral health problems can affect eating habits and thus consequently the nutritional status of frail older people.

Objectives

To assess older service house residents’ dentition and its associations with nutritional status and eating habits, and as well as to explore the prognostic value of dentition status for mortality.

Design

A cross-sectional study with a three-year follow-up.

Methods

In 2007, we assessed the nutritional status of all residents in service houses in the two cities of Helsinki and Espoo in Finland (N=2188). Altogether 1475 subjects (67%) participated in the study; dentition status data were available for 1369 of them. Using a personal interview and assessment, trained nurses familiar to the resident collected the subjects’ demographic data, medical history, functional and cognitive status, information on dentition status, oral symptoms, eating habits and diets. We assessed nutritional status with the Mini Nutritional Assessment (MNA), and retrieved information on mortality from central registers on 6 July 2010.

Results

Edentulousness was common; more than half of the residents (52%) had lost all their teeth: 7% (n=94) were totally edentulous without prosthesis (Group 1), 45% (n=614) had removable dentures (Group 2), and 48% (n = 661) of the residents, had some natural teeth left (Group 3). Dentition status was associated with age, gender, education and disability. According to the MNA, 13% were malnourished, 65% were at risk for malnutrition, and 22% were well nourished. Edentulousness without prosthesis was associated with malnutrition, oral symptoms and infrequent use of oral care services. In Group 1, 52% were deceased during follow-up period. The respective figures for Groups 2 and 3 were 48% and 40% (p=0.004). However, in Cox regression analysis adjusted for age, gender, comorbidity and MNA score, dentition status no longer predicted mortality.

Conclusion

Edentulousness is still common among older service housing residents. Edentulousness without prosthesis was associated with poor nutritional status, oral symptoms and infrequent use of dental services. These findings suggest the need for co-operation between nursing staff and oral care services.     

Multimorbidity type,hospitalizations and emergency department visits among nursing home residents: A preliminary study

Background

The burden of multimorbidity in institutionalized elderly is poorly investigated. We examined the associations of the type of multimorbidity (i.e., physical, mental or both) with the number of hospitalizations and emergency department (ED) visits in nursing home (NH) residents.

Methods

This is a cross-sectional study among NH residents. Information on residents’ health, number of hospitalizations in the last 12 months and hospital department of admission (having been seen in ED vs. non) was recorded by NH staff of 175 French NHs (data was collected in 2011). Participants were screened for the presence of several mental (e.g., dementia) and physical conditions (e.g., diabetes).

Results

Data on hospitalization was available for 6076 NH residents. Compared to having no diseases, the concomitant presence of ≥ 2 physical conditions was the multimorbidity type more strongly associated with both the number of hospitalizations (incidence rate ratio (IRR) =1.93; 95% confidence interval (CI) =1.57 ? 2.37) and ED visits (odds ratio (OR)= 1.79; 95% CI=1.24 ? 2.58). The presence of a mental condition appeared to moderate the associations between physical conditions and hospitalizations, since the estimate effects were lower among people who had both physical and mental conditions, compared to those with only physical conditions. For example, compared to people with ≥ 2 physical conditions, those with multiple physical and mental conditions had lower IRR (IRR = 0.84; 95% CI=0.75 ? 0.95) for the number of hospitalizations.

Conclusions

Mental diseases in very old and multimorbid NH residents probably moderate the associations between physical diseases and hospitalizations. To what extent this represents either a mirror of better clinical practice in NHs or the under-recognition from the NH staff of symptoms leading to justifiable hospitalizations remains unclear.     

Perceptions of Gown and Glove Use to Prevent Methicillin-resistant Staphylococcus aureus Transmission in Nursing Homes

Objectives

To explore current use and perceptions of glove and gown use in nursing homes.

Feasibility and reliability of the mini nutritional assessment (MNA) in older adults with intellectual disabilities

Objective

Feasibility and reliability of the Mini Nutritional Assessment (MNA) in older adults with intellectual disabilities (ID).

Design

Instrument development.

Setting

Three care providers for people with ID.

Participants

48 persons aged 50 years and over with borderline to profound ID and their professional caregivers.

Measurements

The MNA was performed by means of interviews with participants (N = 12) and caregivers (N = 48) and physical assessments of participants (N = 47). Aspects of feasibility: completion of interview, difficulty of answering interview items, duration of interview and completion of physical assessment. Aspects of reliability: inter-observer reliability between caregivers and between participants and caregivers, test-retest reliability and internal consistency. For inter-observer and test-retest reliability, intraclass correlation coefficients (ICC) were calculated, and for internal consistency Chronbach??s alpha.

Results

All participants and caregivers completed the interview part. For 7 out of 12 personally interviewed participants and none of the caregivers, at least 3 out of 15 questions were difficult to answer. Mean duration of the interview was 7 minutes in participants and 4 minutes in caregivers. Physical assessment was successfully performed in 40 participants (85.1%). In the remaining 7 participants (14.9%) missing values were retrieved from the medical records. ICCs (95% confidence interval) for test-retest and inter-observer reliability between caregivers were good, 0.85 (0.72?C0.92) and 0.86 (0.74?C0.92) respectively, but ICC for inter-observer reliability between caregivers and persons with ID was low, 0.03 (?0.51 ?0.59). Internal consistency was 0.61.

Conclusion

The MNA is feasible and reliable for older people with ID. Interview data can be reliably obtained through caregivers, but not through people with ID.     

Use of the Mini Nutritional assessment to detect frailty in hospitalised older people

Objectives

The aims of this study were to: (1) determine the prevalence of undemutrition and frailty in hospitalised elderly patients and (2) evaluate the efficacy of both the Mini-Nutritional Assessment (MNA) screening tool and the MNA short form (MNA-SF) in identifying frailty.

Setting and Participants

A convenient sample of 100 consecutive patients (75.0 % female) admitted to the Geriatric Evaluation and Management Unit (GEMU) at The Queen Elizabeth Hospital in South Australia.

Measurements

Frailty status was determined using Fried??s frailty criteria and nutritional status by the MNA and MNA-SF. Optimal cut-off scores to predict frailty were determined by Youden??s Index, Receiver Operator Curves (ROC) and area under curve (AUC).

Results

Undernutrition was common. Using the MNA, 40.0% of patients were malnourished and 44.0% were at risk of malnutrition. By Fried??s classification, 66.0 % were frail, 30.0 % were pre-frail and 4.0 % robust. The MNA had a specificity of 0.912 and a sensitivity of 0.516 in predicting frailty using the recommended cut-off for malnourishment (< 17). The optimal MNA cut-off for frailty screening was <17.5 with a specificity of 0.912 and sensitivity of 0.591. The MNA-SF predicted frailty with specificity and sensitivity values of 0.794 and 0.636 respectively, using the standard cut-off of < 8. The optimal MNA-SF cut-off score for frailty was < 9, with specificity and sensitivity values of 0.765 and 0.803 respectively and was better than the optimum MNA cut-off in predicting frailty (Youden Index 0.568 vs. 0.503).

Conclusion

The quickly and easily administered MNA-SF appears to be a good tool for predicting both under-nutrition and frailty in elderly hospitalised people. Further studies would show whether the MNA-SF could also detect frailty in other populations of older people.
