Time-Varying Effects of Psychological Distress on the Functional Recovery of Stroke Patients

Latent class analysis and longitudinal development trajectory study of psychological distress in patients with stroke: a study protocol

Background

Psychological distress affects the treatment and rehabilitation of patients with stroke, affects their long-term functional exercise and quality of life, and increases the risk of stroke recurrence and even death. This is a multi-dimensional and multi-level mental health problem and a dynamic process variable that shows a dynamic development trend with time. However, previous studies have been insufficient to deeply study the change mechanism of psychological distress, and there remains a lack of forward-looking longitudinal studies to analyze its change trajectory. This study aimed to investigate potential categories and how psychological distress changes over time and to examine conversion probability in these transformation processes.

Methods

This prospective longitudinal mixed-method study investigated the potential categories and change trajectories of distress in patients with stroke. A total of 492 participants from three hospitals were recruited for quantitative analysis. Latent class analysis and latent transition analysis (LCA/LTA) were used to identify meaningful subgroups, transitions between those classes across time, and baseline demographic features that help predict and design tailored interventions.

Discussion

A comprehensive understanding of the potential category and transformation processes of psychological distress over time, including the impact of the sense of demographic data on the role of shame and loneliness, can lead to the development of psychological distress treatment tailored to the unique needs of patients with stroke. Thus, this study can promote more effective and successful treatment outcomes, reduce the stigma surrounding disease issues among patients, and encourage them to use psychological consultation.

Cerebrovascular risk factors and their time-dependent effects on stroke survival in the EMMA cohort study

To investigate the time-dependent effects of traditional risk factors on functional disability in all-cause mortality post-stroke, we evaluated data from a long-term stroke cohort. Baseline cerebrovascular risk factors (CVRF) and functionality at 1 and 6 months were evaluated in survivors from a prospective stroke cohort using the modified Rankin scale (m-RS), which classifies participants as improvement of disability, unchanged disability (at least moderate), and worsening disability. Cox regression models considering baseline risk factors, medication use, and functionality 6 months after stroke were fitted to identify their time-dependent effects up to 12 years of follow-up. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) are presented. Among 632 survivors (median age 68, 54% male, 71% first-ever episode), age and functional disability (unchanged and worsening) 6 months after ischemic stroke had time-dependent effects on all-cause mortality risk up to 12 years of follow-up. The most impacting risk factors were unchanged (at least moderate) (HR, 2.99; 95%CI: 1.98-4.52) and worsening disability (HR, 2.85; 95%CI: 1.26-6.44), particularly in the first two years after a stroke event (Time 1: ≥6 mo to <2.5 y). Worsening disability also impacted mortality in the period from ≥2.5 to <7.5 years (Time 2) of follow-up (HR, 2.43 (95%CI: 1.03-5.73). Other baseline factors had a fixed high-risk effect on mortality during follow-up. Post-stroke and continuous medication use had a fixed protective effect on mortality. Functional disability was the main contributor with differential risks of mortality up to 12 years of follow-up.

Depressive Symptoms and Anger Expression Among Survivors After Stroke

INTRODUCTION

Stroke is a frequent cause of death and one of the most common causes of disability and depression in the countries of the Western world. Depression is associated with limited functionality, reduced self-care, and increased mortality in patients with stroke. Anger often occurs in these patients and may disrupt the course of their recovery.

AIM

The investigation of the presence of depressive symptomatology, the expression of anger, and the degree of functioning/independence of patients after stroke.

METHOD

One hundred and ten patients after stroke completed the Center for Epidemiological Studies-Depression (CES-D) scale, the State-Trait Anger Expression Inventory, and the Barthel Index.

RESULTS

Patients who lived alone had a higher depressive symptomatology score than patients who did not live alone (p = 0.009). An increase in the total depressive symptomatology score was related to an increase in the anger expression score (p = 0.011), increase in anger-in score (p < 0.001), increase in anger-out score (p < 0.001), and decrease in anger control score (p = 0.001). Females had lower anger-in scores compared to men (p = 0.029). Individuals with a history of previous stroke had higher anger-out scores compared to people without a history of previous stroke (p = 0.025). An increase in the patient's functional/independence score was associated with an increase in anger control score (p = 0.015).

CONCLUSIONS

Early detection and management of depression and anger will facilitate patient's compliance to the rehabilitation program in order to achieve optimal therapeutic results and ensure a better quality of life.

The prevalence and course of neuropsychiatric symptoms in stroke patients impact functional recovery during in-hospital rehabilitation

Background: Neuropsychiatric symptoms are common after stroke and are distressing symptoms. They may persist after the acute event and negatively impact rehabilitation, functioning, and patients' quality of life.Objectives: To elucidate the prevalence and course of neuropsychiatric symptoms in stroke patients during rehabilitation, we prospectively investigated the trajectory change of neuropsychiatric symptoms and the association between these symptoms and functional recovery.Methods: This observational study enrolled 204 stroke patients consecutively admitted to the rehabilitation ward. We administered the Neuropsychiatric Inventory-Nursing Home Version (NPI-NH) for evaluating the neuropsychiatric symptoms (e.g., apathy and depression) and the Functional Independence Measure (FIM) and Montebello Rehabilitation Factor Score (MRFS) for functional recovery.Results: The cumulative prevalence of neuropsychiatric symptoms was 48% during hospitalization; depression, anxiety, and sleep disturbances were most frequent. Binomial logistic regression analyses revealed that the factors associated with deterioration of neuropsychiatric symptoms during hospitalization included premorbid depression (odds ratio: 18.628, P = .001), the length of stay from onset to rehabilitation ward admission (odds ratio: 1.022, P = .012), motor FIM at admission (odds ratio: 0.950, P < .001), and NPI-NH at admission (odds ratio: 0.923, P = .011). Stepwise multiple regression analyses revealed that the NPI-NH at admission was associated with the MRFS (β = -0.128, P = .037).Conclusions: Neuropsychiatric symptoms are common in stroke patients undergoing rehabilitation and have a substantially negative impact on rehabilitation outcomes. Stroke patients with prolonged acute-phase hospitalization and low functioning at admission must be monitored to detect any deterioration in the neuropsychiatric state.

Prevalence and factors associated with suicide ideation and psychiatric morbidity among inpatients of a general hospital: A consecutive three-year study

Using a self-administered questionnaire (the five-item Brief Symptom Rating Scale, BSRS-5), determine the prevalence of suicide ideation (SI), psychiatric morbidity (PM), and the factors associated with these conditions in a general hospital in Taiwan. All individuals aged 12 years or older, who were admitted to a Medical University Hospital between August 2014 and December 2016, were asked to fill out the BSRS-5 at admission. The study was conducted in a medical inpatient setting, excluding Intensive Care Units and the Emergency Service Department. The 93,129 participants were recruited for analysis. Pearson's correlation, regression analysis and path analysis were performed to test the association between SI and each item of psychopathology and to determine the discrimination validity of individual BSRS-5 items for predicting SI. The prevalence rate was 2.3% for SI and 2.0% for PM among all participants. PM was more prevalent in females and those aged 25-54 years. Individuals with PM had a significantly higher rate of SI (44.6%) than did others (1.4%). The prevalence of PM was varied by department, e.g., Psychiatry (44.3%), Rehabilitation Medicine (7.9%), and Nephrology (5.2%). The regression analysis and path analysis with structural equation model indicated that depression, hostility, anxiety, and inferiority were significant independent predictors of SI. The BSRS-5 is an efficient and useful screening tool to identify psychological distress and SI among inpatients in a general hospital. Its integration into the electronic medical chart facilitates identifying patients at risk.

Development and Validation of a Resilience Questionnaire for Patients During Stroke Rehabilitation in China

PURPOSE

The aim of the study was to develop a comprehensive questionnaire for assessing resilience in patients with stroke during rehabilitation and examine the questionnaire's reliability and validity.

DESIGN

A four-phased design was used to develop and validate the questionnaire.

METHODS

The preliminary items of the Resilience Questionnaire for Stroke Rehabilitation (RQSR) were generated through a literature review and a qualitative study. Twenty experts were consulted for content validation and modification of the questionnaire. A pilot study was conducted with 55 patients with stroke. A total of 510 participants from seven rehabilitation centers or hospitals were subsequently recruited to examine the psychometric properties of the RQSR.

RESULTS

The RQSR consists of 35 items within three dimensions. Dimensions include effective rehabilitation training, accessible support system, and appropriate self-regulation. The content validity index of the total questionnaire was .9335. Seven factors were derived through factor analysis, and cumulative contribution rate of variance was 65.455%. Cronbach's alpha of the total questionnaire was .957, with each dimension ranging from .731 to .918, demonstrating high levels of reliability.

CONCLUSION

The RQSR has sound reliability and validity and can be used as an appropriate tool for assessing resilience for patients with stroke during rehabilitation to facilitate effective interventions.

Psychological Distress among Patients Attending Physiotherapy: A Survey-Based Investigation of Irish Physiotherapists' Current Practice and Opinions

Purpose: The primary purpose of this study was to investigate the current practice and opinions of members of the Irish Society of Chartered Physiotherapists (ISCP) with respect to the care of patients in psychological distress. Method: This was a cross-sectional, survey-based investigation of Irish physiotherapists. An electronic survey was sent by email to the ISCP membership. It consisted of closed- and open-ended questions, as well as opinion questions with Likert scale responses. Results: More than 80% of the respondents reported that they encountered patients with psychological distress at least once a week. A lack of education in the area of mental health emerged as a predominant theme. Reflecting on current practice, many discussed the importance of addressing underlying psychological issues before or in tandem with physical issues. Respondents who had engaged in further education in mental health, psychology, or both rated their confidence in recognizing the signs and symptoms of psychological distress higher (p < 0.001). Moreover, a greater proportion of these respondents routinely assessed for psychological distress in their clinical practice (p < 0.001). Conclusion: Physiotherapists regularly encounter patients whom they perceive to have high levels of psychological distress. Irish physiotherapists displayed positive attitudes toward patients' psychological well-being. However, additional education in mental health was a recognized need in the profession.

Effects of Heart Rate Variability Biofeedback in Patients With Acute Ischemic Stroke: A Randomized Controlled Trial

BACKGROUND

Autonomic dysfunction, cognitive impairment, and psychological distress are associated with poorer prognosis in patients with acute ischemic stroke (AIS). Heart rate variability (HRV) biofeedback (BF) improves autonomic dysfunction, cognitive impairment, and psychological distress in other patient populations, but its effect in patients with AIS is still unclear.

OBJECTIVE

This study investigated the effects of an HRVBF intervention on autonomic function, cognitive impairment, and psychological distress in patients with AIS.

METHOD

In this randomized, controlled, single-blind trial, patients with AIS were randomly assigned to the experimental or control group. The experimental group received four HRVBF training sessions. The control group received usual care. Repeated measures of HRV, mini-mental status examination (MMSE), and Hospital Anxiety and Depression Scales (HADS) were collected prior to and at 1 and 3 months postintervention.

RESULTS

A total of 35 patients completed the study (19 experimental, 16 control). HRV and HADS significantly improved in the experimental group (p < .001) but not in the control group. Likewise, only the experimental group showed significant improvements in HRV, MMSE, and HADS over time (p < .05).

CONCLUSION

HRVBF is a promising intervention for improving autonomic function, cognitive impairment, and psychological distress in patients with AIS. More studies of HRVBF interventions are needed to further optimize the effects of HRVBF on autonomic, cognitive, and psychological function in patients with AIS.

Sex Differences in Patient-Reported Poststroke Disability

BACKGROUND

Recent studies have shown that stroke has a differential impact in women compared to men. Women are more likely to survive strokes than men, yet they experience more severe strokes resulting in greater poststroke disability. However, few studies have characterized sex differences in functional ability after stroke. This study examined sex differences in long-term disability among stroke survivors.

METHODS

This was a retrospective analysis of the 2015 National Health Interview Survey. Respondents were asked to rate their ability to perform 11 functional tasks. Univariate comparisons were completed to evaluate sex differences in performance, and multinomial logistic regression was used to determine the odds of reporting functional limitations.

RESULTS

Five hundred fourteen men and 641 women stroke survivors completed the survey (mean age: 66.9 years). Approximately 75% of the sample reported having hypertension, 61% high cholesterol, 33% diabetes, 24% heart disease, 21% heart attack, and 16% chronic obstructive pulmonary disease. In the predictive models, men were less likely to report "very difficult/can't do at all" in walking ¼ mile (odds ratios [OR] = 0.68, 95% CI 0.51-0.90), climbing 10 steps (OR = 0.65, 95% CI 0.49-0.85), standing 2 hours (OR = 0.66, 95% CI 0.50-0.87), stooping (OR = 0.51, 95% CI 0.39-0.68), reaching overhead (OR = 0.69, 95% CI 0.49-0.97), carrying 10 pounds (OR = 0.45, 95% CI 0.34-0.59), and pushing large objects (OR = 0.37, 95% CI 0.28-0.5) compared to women.

CONCLUSIONS

The functional outcomes of men stroke survivors were significantly greater than women. The specific factors that contribute to sex differences in stroke-related outcomes are not entirely clear. Future research is needed to better understand these differences to ensure that equity of care is received.
