Conversion of the Mini-Mental State Examination to the International Classification of Functioning, Disability and Health terminology and scoring system

Development of a Conversion Table Linking Functional Independence Measure Scores to International Classification of Functioning, Disability, and Health Qualifiers: Insights from a Survey of Healthcare Professionals

In clinical practice, patient assessments rely on established scales. Integrating data from these scales into the International Classification of Functioning, Disability, and Health (ICF) framework has been suggested; however, a standardized approach is lacking. Herein, we tested a new approach to develop a conversion table translating clinical scale scores into ICF qualifiers based on a clinician survey. The survey queried rehabilitation professionals about which functional independence measure (FIM) item scores (1-7) corresponded to the ICF qualifiers (0-4). A total of 458 rehabilitation professionals participated. The survey findings indicated a general consensus on the equivalence of FIM scores with ICF qualifiers. The median value for each item remained consistent across all item groups. Specifically, FIM 1 had a median value of 4; FIM 2 and 3 both had median values of 3; FIM 4 and 5 both had median values of 2; FIM 6 had a median value of 1; and FIM 7 had a median value of 0. Despite limitations due to the irreconcilable differences between the frameworks of existing scales and the ICF, these results underline the ICF's potential to serve as a central hub for integrating clinical data from various scales.

Application of the International Classification of Functioning, Disability and Health (ICF) in dementia research and practice: A scoping review

OBJECTIVES

The International Classification of Functioning, Disability and Health (ICF) endorsed by the World Health Organization provides a conceptual framework for describing functioning and disability based on a biopsychosocial model. Although dementia is one of the leading causes of disability, yet little is known on the extent to how the ICF has been utilized in dementia research and practice. The study aimed to examine and map the current applications of the ICF with dementia from a body of earlier studies and to explore the potential use in person-centred dementia care.

METHODS

The Arksey and O'Malley framework was used to guide the searching, selecting, and synthesizing process. The scoping review was reported following The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Review (PRISMA-ScR) guidelines.

RESULTS

A total of 34 studies were included. The applications of ICF were classified into 4 themes: (1) in clinical practice and the education of health professionals (n = 20); (2) community support services and income support (n = 3); (3) population-based, census, or survey data (n = 10); (4) advocacy and empowerment purposes (n = 1).

CONCLUSION

The ICF has made a major impact on dementia in clinical settings. Findings strongly support applying the ICF to person-centered dementia care. In the future, more empirical studies are needed to expand the scope of ICF use in dementia research and practice.

[Smartphone-based health promotion in old age : An explorative multi-component approach to improving health in old age]

BACKGROUND

As age-related health problems are often related to a combination of physiological, psychological and social aspects, it has been proposed that multi-component interventions might be particularly effective to improve older peoples' health. The present study used a smartphone-based approach to promote health through activities including physical as well as cognitive components performed in a daily life context.

METHODS

This study investigated the effects of different health-related variables (e.g. gait and cognition) as well as the individual motivation for physical activity. The study included 34 community-dwelling older adults (mean age 75.0 ± 3.7 years, 15 women) who took part either in smartphone-based activities (intervention group) or attended lectures (control group). The smartphone-based interventions were undertaken semiweekly.

RESULTS

Baseline tests showed that participants in both groups already had a high motivation for physical activities. Analyses indicated that the smartphone application was considered to be user-friendly.

CONCLUSION

There were no substantial health-related benefits from the activities, probably due to moderate to good health status and activity levels at baseline and too little additional activity intensity during the intervention. Hence, it is recommended that for future research the subjects included should be less active or have health restrictions.

A new scoring system for increasing the sensitivity of the MMSE

BACKGROUND

The mini mental state examination (MMSE) has been criticized for its lack of sensitivity, especially in mild cases of dementia. There have been several attempts to increase the sensitivity by adding or deleting items, which never became accepted in clinical practice.

OBJECTIVE

In the current study a new scoring system for improving the sensitivity of the MMSE is proposed, which preserves the original items and the total score of 30 points. Instead of changing the number of items or the total score of 30 points, the weighting of the different items in the total score of 30 points was changed.

MATERIAL AND METHODS

Neuropsychological test data of 765 patients were retrospectively included in the study to determine the difficulty of each MMSE item. Multiple scoring systems for the MMSE were developed by inclusion of the item difficulty and clinical relevance. The sensitivity of the new scoring system was compared to the original scoring system by using the DemTect as an established measure.

RESULTS

The results showed that an increase of 24.3% in sensitivity was statistically significant. Within the mild cognitive impairment subgroup, the sensitivity of the new scoring system was twice as high in comparison to the original MMSE and within the dementia group the sensitivity was increased by 8.2%.

CONCLUSION

A new scoring system with a higher sensitivity than the original MMSE was developed, which can easily be administered in clinical practice because it preserves all items and the total score of 30 points.

Improving clarity and transparency in cognitive assessment: conversion of the Cambridge Cognition Examination to the International Classification of Functioning, Disability and Health

BACKGROUND

A variety of screening, diagnostic and assessment tools have been developed for use in dementia research and care. However, there is no consensus which tool to use and moreover there is no transparency in communication between countries and disciplines.

OBJECTIVE

To contribute to a more uniform assessment in dementia, the Cambridge Cognition Examination (CAMCOG) was converted to the International Classification of Functioning, Disability and Health (ICF).

METHODS

In a qualitative design, CAMCOG-items and -scoring-system were converted to the ICF addressing 3 ICF domains: global and specific mental functions and general tasks and demands. Construct and discriminative validity was checked in a sample of 25 cognitively healthy elderly (CHE), 25 persons with Mild Cognitive Impairment (MCI) and 25 patients with mild Alzheimer's Disease (mAD).

RESULTS

A significant correlation was observed between CAMCOG/ICF-CAMCOG (r = - 0.987; p < 0.01). The areas under the curve (AUC) of the ICF-CAMCOG were between 0.819 and 0.978; comparable with the original CAMCOG. Only a significant difference between the AUC of the CHE versus MCI (0.911 vs. 0.819; p = 0.0094) was observed in favour of CAMCOG.

CONCLUSION

The clinical use of the ICF-CAMCOG looks promising offering a more detailed and interpretable scoring and may allow for better planning of resources to aid patients with dementia.

Linking Frailty Instruments to the International Classification of Functioning, Disability, and Health: A Systematic Review

To date, the major dilemma concerning frailty is the lack of a standardized language regarding its operationalization. Considering the demographic challenge that the world is facing, standardization of frailty identification is indeed the first step in tackling the burdensome consequences of frailty. To demonstrate this diversity in frailty assessment, the available frailty instruments have been linked to the International Classification of Functioning, Disability, and Health (ICF): a standardized and hierarchically coded language developed by World Health Organization regarding health conditions and their positive (functioning) and negative (disability) consequences. A systematic review on frailty instruments was carried out in PubMed, Web of Knowledge, and PsycINFO. The items of the identified frailty instruments were then linked to the ICF codes. 79 original or adapted frailty instruments were identified and categorized into single (n = 25) and multidomain (n = 54) groups. Only 5 frailty instruments (indexes) were linked to all 5 ICF components. Whereas the ICF components Body Functions and Activities and Participation were frequently linked to the frailty instruments, Body Structures, Environmental and Personal factors were sparingly represented mainly in the multidomain frailty instruments. This review highlights the heterogeneity in frailty operationalization. Environmental and personal factors should be given more thought in future frailty assessments. Being unambiguous, structured, and neutral, the ICF language allows comparing observations made with different frailty instruments. In conclusion, this systematic overview and ICF translation can be a cornerstone for future standardization of frailty assessment.

Feasibility of Applying the Extended ICF Core Set for Stroke to Clinical Settings in Rehabilitation: A Preliminary Study

Objective

To evaluate the potential feasibility of application of the extended International Classification of Functioning, Disability and Health (ICF) Core Set for stroke.

Methods

We retrospectively reviewed the medical records of 40 stroke outpatients (>6 months after onset) admitted to the Department of Rehabilitation Medicine for comprehensive rehabilitation. Clinical information of the patients were respectively evaluated to link to the 166 second-level categories of the extended ICF Core Set for stroke.

Results

Clinical information could be linked to 111 different ICF categories, 58 categories of the body functions component, eight categories of the body structures component, 38 categories of the activities and participation component, and seven categories of the environmental factors component.

Conclusion

The body functions component might be feasible for application of the extended ICF Core Set for stroke to clinical settings. The activities and participation component and environmental factors component may not be directly applied to clinical settings without additional evaluation tools including interview and questionnaire.

Test Your Memory (TYM) as a screening instrument in clinical practice - the Polish validation study

OBJECTIVES

The Test Your Memory (TYM) test is a short, self-administered screening cognitive instrument designed for the detection of Alzheimer's disease (AD). The study was aimed to examine the Polish version of TYM as a screening instrument in Polish clinical practice.

METHOD

In this study 199 patients were assessed whereas 131 patients with AD and mild cognitive impairments (MCI) and 94 healthy control subjects took part in the final analysis. The sensitivity and specificity of the TYM test were evaluated among the AD group and healthy control group. The TYM test was compared to other neuropsychological tests, such as Mini-Mental State Examination (MMSE), Clock Drawing Test (CDT), DemTect and Verbal Fluency Test (FAS).

RESULTS

The average TYM score in healthy control group: 45.4, 40.9 in the MCI patients and 23.4 in AD patients. The Polish version of the TYM test showed good correlation with other neuropsychological instruments among AD patients. Participants aged ≥75 and those with primary education performed significantly worse in TYM. The TYM achieved the best differentiation between AD and the healthy control group for ≤39 cut-off with a sensitivity and specificity of 91% and 90%, respectively.

CONCLUSION

The Polish version of the TYM test is a useful instrument and may be seen as an alternative to the MMSE screening test in clinical practice in patients with dementia. However, the normative data suggested that the age and the level of education of the respondents should be considered as important factors affecting the interpretation of the final score.
