Extrinsic and Behavioral Fall Risk Factors in People With Parkinson's Disease: An Integrative Review

Psychometric properties of the Brazilian-Portuguese version of the Falls Behavioral Scale in people with Parkinson's disease

PURPOSE

To verify the psychometric properties of the Brazilian-Portuguese version of the Falls Behavioral (FaB-Brazil) Scale in Parkinson's disease (PD).

MATERIAL AND METHODS

Participants (n = 96) were assessed by disease-specific, self-report and functional mobility measures. Internal consistency of the FaB-Brazil scale was evaluated using Cronbach's alpha and inter-rater and test-retest reliability using intraclass correlation coefficients (ICC). The standard error of measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, and convergent and discriminative validity were evaluated.

RESULTS

Internal consistency was moderate (α = 0.77). Excellent inter-rater (ICC = 0.90; p < 0.001) and test-retest (ICC = 0.91; p < 0.001) reliability were found. The SEM was 0.20 and MDC was 0.38. Ceiling and floor effects were not found. Convergent validity was established by the positive correlations between the FaB-Brazil scale and age, modified Hoehn and Yahr, PD duration, Movement Disorders Society-Unified Parkinson's Disease Rating Scale, Motor Aspects of Experiences of Daily Living, Timed Up & Go and 8-item Parkinson's Disease Questionnaire, and negative correlations between the FaB-Brazil scale and community mobility, Schwab & England, and Activities-specific Balance Confidence scale. Females showed greater protective behaviors than males; recurrent fallers showed greater protective behaviors than non-recurrent fallers (p < 0.05).

CONCLUSIONS

The FaB-Brazil scale is reliable and valid for assessing people with PD.

Data-Driven Analytics to Discover APRN's Impact on Nursing Home Hospitalization: Causal Discovery Analysis

OBJECTIVES

Research shows advanced practice registered nurses (APRNs) embedded in nursing homes (NHs) reduce resident hospitalizations. However, the specific APRN activities that reduce hospitalizations have not been adequately investigated. This study aims to identify the causal links between APRN activities and NHs resident hospitalization. The study also examined relationships among other variables, including advanced directives, clinical diagnosis, and length of hospitalization.

DESIGN

Secondary data analysis.

SETTING AND PARTICIPANTS

Residents of NHs participating in the Missouri Quality Initiative for Nursing Homes, 2016-2019.

METHODS

We performed a secondary analysis of data from the Missouri Quality Initiative for Nursing Homes Intervention using causal discovery analysis, a machine learning, data-driven technique to determine causal relationships across data. The resident roster and INTERACT resident hospitalization datasets were combined to create the final dataset. Variables in the analysis model were divided into before and after hospitalization. Expert consensus was used to validate and interpret the outcomes.

RESULTS

The research team analyzed 1161 hospitalization events and their associated NH activities. APRNs evaluated NH residents before a transfer, expedited follow-up nursing assessments, and authorized hospitalization when necessary. No significant causal relationships were found between APRN activities and the clinical diagnosis of a resident. The analysis also showed multifaceted relationships related to having advanced directives and duration of hospitalization.

CONCLUSIONS AND IMPLICATIONS

This study demonstrated the importance of APRNs embedded in NHs to improve resident outcomes. APRNs in NHs can facilitate communication and collaboration among the nursing team, leading to early identification and treatment for resident status changes. APRNs can also initiate more timely transfers by reducing the need for physician authorization. These findings emphasize the crucial role of APRNs in NHs and suggest that budgeting for APRN services may be an effective strategy to reduce hospitalizations. Additional findings regarding advance directives are discussed.

Rising From the Floor in Persons With Parkinson's Disease

Although considerable research has targeted fall prevention among older adults with Parkinson's disease (PD), less is known about their ability to rise from the floor. The aim of the current exploratory study was to examine the relationship between floor rise and physical performance tests. A cross-sectional design was used. Twenty community-dwelling older adults with PD (mean age = 74.8 years, SD = 9.5 years) performed a standardized floor rise test and physical performance assessments in a structured task circuit. Mean time to rise from the floor was 14.9 seconds (SD = 7.6 seconds). Fourteen (70%) participants used a quadruped strategy to rise to stand. Supine-to-stand performance time was significantly correlated with all physical performance measures. Findings serve as a catalyst for nursing and rehabilitation professionals to examine floor rise ability, prevent adverse effects of a critical fall, and instruct fall recovery techniques in clinical settings.

Predictors of Falls with Injuries in People with Parkinson's Disease

Background

Falls are frequent in Parkinson's disease (PD), but there is lack of information about predictors of injurious falls.

Objectives

To determine predictors of falls with injuries in people with PD; to compare circumstances and consequences of falls in single and recurrent fallers.

Methods

Participants (n = 225) were assessed by disease-specific, self-report, and balance measures, and followed-up for 12 months with a diary to record falls, their circumstances, and injuries. Univariate and multivariate analyses were performed. Circumstances and consequences of falls presented by single and recurrent fallers were compared.

Results

A total of 805 falls were analyzed, 107 (13%) were falls with injuries. Multivariate logistic regression model revealed that greater PD duration and higher balance confidence were protective factors; better balance during gait, outdoor falls, and falls related to extrinsic factors were risk factors for falls with injuries, when compared to falls with no injuries. Multivariate multinomial regression model revealed that, when compared to zero fall, past falls and daily levodopa equivalent dose were predictors of falls with injuries; these predictors together with disability were predictors of falls with no injuries. Single falls (n = 27; 3%) were more common outdoors because of extrinsic factors, whereas recurrent falls (n = 778; 97%) were more common indoors because of intrinsic factors. Single falls led to more injuries than recurrent falls (P < 0.05).

Conclusions

Different predictors of falls with injuries were obtained when different outcomes were compared. It should be noted that falls with injuries might be influenced by fall-related activities and environmental factors. Single and recurrent falls differed on circumstances and consequences.

Assessing the relationship between hearing impairment and falls in older adults

Falls and fall-related injuries are the major sources of mortality, disability, and dysfunction among older people. The study aimed to examine the association between hearing impairment and falls in Chinese older adults, using data from the Chinese Longitudinal Healthy Longevity Survey. The outcome variable was experienced falls in the past year, and the exposure variable was hearing impairment. The odds ratio (OR) of falls was 1.51 and 1.47 for men and women with hearing impairment than those without hearing impairment after adjusting for covariates. For participants aged 60-69 years, 70-79 years, 80-89 years, and ≥ 90 years, the OR of risk of falls associated with hearing impairment was 2.80, 1.41, 1.50 and 1.44, respectively. These results suggested that there was an association between hearing impairment and falls. Older adults with hearing impairment had a higher risk of falls than those without hearing impairment in the Chinese older population.
