Evaluation of the Short Form of the Late-Life Function and Disability Instrument in Geriatric Inpatients—Validity, Responsiveness, and Sensitivity to Change: SELF-REPORT OF PHYSICAL FUNCTION IN INPATIENTS (original) (raw)

Validation of the Late-Life Function and Disability Instrument

Journal of the American Geriatrics Society, 2000

OBJECTIVES: To assess the concurrent and predictive validity of the Late-Life Function and Disability Instrument (LLFDI). DESIGN: Cross-sectional. SETTING: University-based human physiology laboratory. PARTICIPANTS: One hundred one men and women aged 80.8 AE 0.4. MEASUREMENTS: A short physical performance battery (SPPB) and a self-paced 400-m walk (400-m W) were used as performance tests of lower extremity function. The LLFDI was used to assess self-reported function and physical disability. Partial correlations adjusted for age and body mass index were used to determine the concurrent and predictive validity of the LLFDI. Statistical significance was accepted at Po.004 using a testwise correction. RESULTS: LLFDI Overall Function scores were moderately associated with the SPPB (r 5 0.65, Po.001), 400-m W gait speed (r 5 0.69, Po.001), and measures of lower extremity function. Correlations of the two lower extremity subscores of the LLFDI (correlation coefficient (r) 5 0.63-0.73, Po.001) were greater than for the LLFDI upper extremity subscores (r 5 0.19-0.26, P4.004). Performance measures of function predicted disability limitations in the range of r 5 0.37-0.44 (Po.001) and disability frequency in the range of r 5 0.16-0.20 (P4.004). CONCLUSION: These findings support the concurrent and predictive validity of the LLFDI. Results support the use of the LLFDI scales as a substitute for physical performance tests when self-report is a preferred data-collection format.

Archives of Physical Medicine and Rehabilitation, 2006

Brooks D, Davis AM, Naglie G. Validity of 3 physical performance measures in inpatient geriatric rehabilitation. Arch Phys Med Rehabil 2006;87:105-10. Objective: To evaluate the construct validity and the responsiveness of 3 measures of physical performance measures as outcome measures for frail older persons. Design: Pre-post design with measures at admission and discharge. Setting: Three inpatient geriatric rehabilitation programs. Participants: Fifty-two subjects (35 women, 17 men; age, 80Ϯ8y). Interventions: Not applicable. Main Outcome Measures: Physical performance measures were Timed Up & Go (TUG) test, two-minute walk test (2MWT), and functional reach. Functional status was measured with the FIM instrument and the Modified Barthel Index.

An Individualized Approach to Outcome Measurement in Geriatric Rehabilitation

The Journals of Gerontology Series A: Biological Sciences and Medical Sciences, 1999

Background. The heterogeneity of health problems experienced by frail elderly patients makes it difficult to use a single standard measure to evaluate multiple outcomes of geriatric rehabilitation. Commonly, several measures are used, but an alternative is to use an individualized measure such as Goal Attainment Scaling (GAS). This study investigated the reliability, validity, and responsiveness of GAS as an outcome measure in geriatric rehabilitation. Methods. We studied 173 consecutive admissions (mean age 81; 77% female; mean length of stay 33 days) to a geriatric rehabilitation unit. Assessment instruments were completed at admission and discharge. Individualized treatment goals were identified for each patient by using GAS; standardized measures included self-rated health, a global clinical assessment, the Barthel Index, the OARS IADL scale, the Folstein Mini-Mental State Examination (MMSE), and the Nottingham Health Profile (NHP). Results. Mobility, future care arrangements, and functional impairment were the most commonly identified GAS goal areas. The interrater reliability of the GAS discharge score was 0.93. The GAS discharge score correlated strongly (r~0.50) with the standardized measures, except for self-rated health, the MMSE, and the NHP (r~0.31). GAS was more responsive to change than any of the standardized measures. The GAS score was used to derive receiver operating characteristic curves for other measures; this can provide insight into the interpretation of clinically important outcomes. Conclusions. GAS appears to be a feasible, reliable, valid, and responsive approach to outcome measurement in geriatric rehabilitation.

Assessment Tools for the Admission of Older Adults to Inpatient Rehabilitation: A Scoping Review

Journal of Clinical Medicine

(1) Objective: To identify the assessment tools and outcome measures used to assess older adults for inpatient rehabilitation. (2) Design: Scoping review. (3) Data sources: ProQuest, PEDro, PubMed, CINAHL Plus with full text (EBSCO), Cochrane Library and reference lists from included studies. (4) Review method: The inclusion of studies covering patients aged >60, focusing on rehabilitation assessments delivered in hospitals in community settings. Studies reporting on rehabilitation specifically designed for older adults-testing for at least one domain that affects rehabilitation or assessments for admission to inpatient rehabilitation-were also included. Results were described both quantitatively and narratively. (5) Results: 1404 articles were identified through selected databases and registers, and these articles underwent a filtering process intended to identify and remove any duplicates. This process reduced the number to 1186 articles. These, in turn, were screened for inclusion criteria, as a result of which 37 articles were included in the final review. The majority of assessments for geriatric rehabilitation were carried out by a multidisciplinary team. Multiple studies considered more than one domain during assessment, with a high percentage evaluating a specific outcome measure used in geriatric rehabilitation. The most common domains assessed were function, cognition and medical status-with communication, vision and pain being the least common. A total of 172 outcome measures were identified in this review, with MMSE, BI, FIM and CCI being the most frequent. (6) Conclusions: This review highlights the lack of standardised approaches in existing assessment processes. Generally, older-adult-rehabilitation assessments struggle to capture rehabilitation potential in a holistic manner. Hence, a predictive model of rehabilitation for assessing patients at the initial stages would be useful in planning a patient-specific programme aimed at maximising functional independence and, thus, quality of life.

Responsiveness of Mobility, Daily Living, and Instrumental Activities of Daily Living Outcome Measures for Geriatric Rehabilitation

Archives of Physical Medicine and Rehabilitation, 2010

Objectives: To assess and compare the ability of the Timed Up & Go (TUG) and subscales of the Functional Autonomy Measurement System (SMAF) to detect change in people undergoing geriatric rehabilitation in inpatient geriatric rehabilitation units (GRUs) and day hospitals. Design: Longitudinal design with repeated measures obtained at admission and discharge from rehabilitation and at 2 follow-up interviews. Setting: Inpatient and outpatient hospital-based settings. Participants: Subjects (Nϭ237, age 80Ϯ7y) had data at admission and discharge from rehabilitation (changing time frame), and of these, 160 had data at 2 subsequent follow-ups (stable time frame). Interventions: Not applicable. Main Outcome Measures: The TUG was used to estimate basic mobility, and subscales of the SMAF were used to estimate general mobility (SMAF-mobility), basic activities of daily living (SMAF-ADL), and instrumental activities of daily living (SMAF-IADL). Professionals' perception of change was used as a criterion. Results: The TUG generated large values for the standardized response mean (SRM) and Guyatt's responsiveness index in GRUs (.98 and 1.12) and day hospitals (.89 and 1.85). Professionals' perception of change in mobility was explained by a perceptible change in the TUG in day hospitals (15%) but not in GRUs. The SMAF-mobility, SMAF-ADL, and SMAF-IADL were associated with large values of SRM and Guyatt's responsiveness index in GRUs (.97-2.17) and with small to moderate values in day hospitals (.29-.54). Moderate to large portions in the professionals' perceptions of change for mobility (20%, 17%), basic ADLs (10% and 14%), and IADLs (23% and 19%) were associated with the respective change scores of the subscales of the SMAF in both GRUs and day hospitals. Conclusions: Progress of older adults in the areas of mobility, basic ADLs, and IADLs can be captured using the TUG, SMAF-mobility, SMAF-ADL, and SMAF-IADL in both GRUs and day hospitals. The results support their use in settings of high-and low-intensity rehabilitation, thus suggesting their adequacy for use in these 2 settings.

Translation, validation and reliability of the Dutch late-life function and disability instrument computer adaptive test

Physiotherapy, 2015

Background. Adequate and user-friendly instruments for assessing physical function and disability in older adults are vital for estimating and predicting health care needs in clinical practice. The Late-Life Function and Disability Instrument Computer Adaptive Test (LLFDI-CAT) is a promising instrument for assessing physical function and disability in gerontology research and clinical practice. Objective. The aims of this study were: (1) to translate the LLFDI-CAT to the Dutch language and (2) to investigate its validity and reliability in a sample of older adults who spoke Dutch and dwelled in the community. Design. For the assessment of validity of the LLFDI-CAT, a cross-sectional design was used. To assess reliability, measurement of the LLFDI-CAT was repeated in the same sample. Methods. The item bank of the LLFDI-CAT was translated with a forward-backward procedure. A sample of 54 older adults completed the LLFDI-CAT, World Health Organization Disability Assessment Schedule 2.0, RAND 36-Item Short-Form Health Survey physical functioning scale (10 items), and 10-Meter Walk Test. The LLFDI-CAT was repeated in 2 to 8 days (meanϭ4.5 days). Pearson's r and the intraclass correlation coefficient (ICC) (2,1) were calculated to assess validity, group-level reliability, and participant-level reliability. Results. A correlation of .74 for the LLFDI-CAT function scale and the RAND 36-Item Short-Form Health Survey physical functioning scale (10 items) was found. The correlations of the LLFDI-CAT disability scale with the World Health Organization Disability Assessment Schedule 2.0 and the 10-Meter Walk Test were Ϫ.57 and Ϫ.53, respectively. The ICC (2,1) of the LLFDI-CAT function scale was .84, with a group-level reliability score of .85. The ICC (2,1) of the LLFDI-CAT disability scale was .76, with a group-level reliability score of .81. Limitations. The high percentage of women in the study and the exclusion of older adults with recent joint replacement or hospitalization limit the generalizability of the results. Conclusions. The Dutch LLFDI-CAT showed strong validity and high reliability when used to assess physical function and disability in older adults dwelling in the community.

Psychometric properties of the Late-Life Function and Disability Instrument: a systematic review

BMC Geriatrics, 2014

Background: The choice of measure for use as a primary outcome in geriatric research is contingent upon the construct of interest and evidence for its psychometric properties. The Late-Life Function and Disability Instrument (LLFDI) has been widely used to assess functional limitations and disability in studies with older adults. The primary aim of this systematic review was to evaluate the current available evidence for the psychometric properties of the LLFDI. Methods: Published studies of any design reporting results based on administration of the original version of the LLFDI in community-dwelling older adults were identified after searches of 9 electronic databases. Data related to construct validity (convergent/divergent and known-groups validity), test-retest reliability and sensitivity to change were extracted. Effect sizes were calculated for within-group changes and summarized graphically. Results: Seventy-one studies including 17,301 older adults met inclusion criteria. Data supporting the convergent/ divergent and known-groups validity for both the Function and Disability components were extracted from 30 and 18 studies, respectively. High test-retest reliability was found for the Function component, while results for the Disability component were more variable. Sensitivity to change of the LLFDI was confirmed based on findings from 25 studies. The basic lower extremity subscale and overall summary score of the Function component and limitation dimension of the Disability component were associated with the strongest relative effect sizes. Conclusions: There is extensive evidence to support the construct validity and sensitivity to change of the LLFDI among various clinical populations of community-dwelling older adults. Further work is needed on predictive validity and values for clinically important change. Findings from this review can be used to guide the selection of the most appropriate LLFDI subscale for use an outcome measure in geriatric research and practice.

Predictors of Functional Improvement in Geriatric Rehabilitation Units. A Multicenter Study

Innovation in Aging, 2017

Older people suffering from a hip fracture are at increased risk of functional decline. In The Trondheim Hip Fracture Trial we monitored activity the fourth day and 4 and 12 months post-surgery (n= 397). Patients randomised to receive treatment in an orthogeriatric ward spent more time upright than patients treated in a traditional orthopaedic ward. The differences lasted at 4/12 months. In the EVA-Hip study (n=143), we assessed the effect of 10 weeks individualised, task oriented home-exercise delivered four months after hip surgery and compared this to ususal care. Results demonstrated an improvement in gait speed in the intervention group, but with no change in time spent upright between the two groups.
