Subjective and objective nutritional assessment: nurses' role and the effect of cultural differences.

ABSTRACT:

Background

Even though the nutritional assessment of chronically ill patients has a significant effect on outcomes, nurses' time constraints in clinical encounters may make the process impractical. Also, cultural background has an effect on nutritional assessment. Patient nutritional self-assessment can ease some of the nurses' workload.

Objectives

To compare tools for subjective and objective nutritional assessment and to examine cultural differences in nutritional assessment between Jews and Arabs living in Israel.

Methods

The research design was cross-sectional; data were collected from Jews and Arabs with chronic illnesses living in the community during their visit to a public health clinic. The admitting nurse performed an objective nutritional assessment (Mini Nutritional Assessment (MNA)) after the patients completed the Subjective Nutritional Assessment (SANS). The data were analyzed using descriptive statistics, Pearson's correlation coefficients were calculated to test the relationships between the variables, and independent student t-tests were used to compare the means and differences between groups. The diagnostic accuracy of the MNA and of the SANS was determined using the area under the curve (AUC) analysis of receiver operating characteristic (ROC) curves. The agreement between the MNA and SANS measurements was estimated by a Bland Altman plot. The level of significance employed throughout the analysis was 0.05.

Results

The sample was a convenience sample of 228 chronically ill patients, consisting of 121 Arabs and 107 Jews. A significant correlation was found between the subjective and objective nutritional assessments. The Bland-Altman plot demonstrated that the SANS and the MNA have a high level of agreement. Using the area under the curve (AUC) analysis of receiver operating characteristic (ROC) curves, showed an moderate diagnostic accuracy (73 % sensitivity and 30 % specificity).

Conclusions

Since the patient-completed nutritional assessment requires minimal time investment by nurses and we found a significant correlation and evidence for the accuracy and agreement of the objective and subjective assessments, further studies should assess and validate the possibility of replacing the objective nutritional assessment by the subjective assessment. Cultural background has a significant effect on patients' nutritional self-assessment; hence, culture should be considered as part of the nutritional assessment.

Project description:Advances in wearable technology allow for the objective assessment of motor performance in both in-home and in-clinic environments and were used to explore motor impairments in Parkinson's disease (PD). The aims of this study were to: 1) assess differences between in-clinic and in-home gait speed, and sit-to-stand and stand-to-sit duration in PD patients (in comparison with healthy controls); and 2) determine the objective physical activity measures, including gait, postural balance, instrumented Timed-up-and-go (iTUG), and in-home spontaneous physical activity (SPA), with the highest correlation with subjective/semi-objective measures, including health survey, fall history (fallers vs. non-fallers), fear of falling, pain, Unified Parkinson's Disease Rating Scale, and PD stage (Hoehn and Yahr). Objective assessments of motor performance were made by measuring physical activities in the same sample of PD patients (n = 15, Age: 71.2±6.3 years) and age-matched healthy controls (n = 35, Age: 71.9±3.8 years). The association between in-clinic and in-home parameters, and between objective parameters and subjective/semi-objective evaluations in the PD group was assessed using linear regression-analysis of variance models and reported as Pearson correlations (R). Both in-home SPA and in-clinic assessments demonstrated strong discriminatory power in detecting impaired motor function in PD. However, mean effect size (0.94±0.37) for in-home measures was smaller compared to in-clinic assessments (1.30±0.34) for parameters that were significantly different between PD and healthy groups. No significant correlation was observed between identical in-clinic and in-home parameters in the PD group (R = 0.10-0.25; p>0.40), while the healthy showed stronger correlation in gait speed, sit-to-stand duration, and stand-to-sit duration (R = 0.36-0.56; p<0.03). This suggests a better correlation between supervised and unsupervised motor function assessments in healthy controls compared to PD group. In the PD group, parameters related to velocity and range-of-motion of lower extremity within gait assessment (R = 0.58-0.84), and turning duration and velocity within iTUG test (R = 0.62-0.77) demonstrated strong correlations with PD stage (p<0.01).

Project description:ObjectivesTo investigate the correlation of objective audiometry with user satisfaction as measured with the questionnaire scores.MethodsTwenty patients with hearing loss, who agreed to wear a hearing aid and were referred for hearing aid fitting, were included in this prospective clinical study. All patients used the in-the-canal type of Wide7 hearing aid provided by BSL Co., Ltd. We performed the Korean version of the Hearing Handicap Inventory for the Elderly (K-HHIE) and the International Outcome Inventory for Hearing Aids (K-IOI-HA) before and 1, 3, and 6 months after wearing the hearing aid. We also performed pure tone audiometry (PTA), speech audiometry (SA), functional gain (FG), hearing in noise test (HINT), and central auditory processing disorder tests, such as frequency pattern test (CA-f), duration pattern test (CA-d), and dichotic test (CA-Di). Patients were divided into two groups (group A-HHIE, improved; group B-HHIE, same or worse) by comparing the score of K-HHIE before and 6 months after wearing the hearing aid. In the 6-month K-IOI-HA questionnaire, 21 points were considered as the average score. Based on this, we further divided patients into two groups (group A-IOI, >21 points; group B-IOI, ≤21 points).ResultsGroup A-HHIE included six patients and group B-HHIE included 14 patients. In PTA, SA, HINT, CA-d, and CA-Di, group A-HHIE showed higher improvements than group B-HHIE, which were not statistically significant. Group A-IOI included 12 patients and group B-IOI included eight patients. No statistically significant difference was noted in the improvement of audiometric results over a period of 6 months after wearing the hearing aid between groups A-IOI and B-IOI.ConclusionThere were no significant and consistent audiometric results to reflect patient's satisfaction with the hearing aid. Therefore, when analyzing the hearing aid-fitting outcome, both the objective audiometric tests and subjective questionnaire should be performed together for validating hearing aid performance.
