Item Banks for Measuring the Effect of Blood Pressure Dysregulation on Health-Related Quality of Life in Persons With Spinal Cord Injury

OBJECTIVE

To report on the development and calibration of the new Blood Pressure Dysregulation Measurement System (BPD-MS) item banks that assess the effect of BPD on health-related quality of life (HRQOL) and the daily activities of Veterans and non-Veterans with spinal cord injury (SCI).

DESIGN

Cross-sectional survey study.

SETTING

Two Veteran Affairs medical centers and a SCI model system site.

PARTICIPANTS

454 respondents with SCI (n=262 American Veterans and n=192 non-Veterans; N=454).

INTERVENTIONS

Not applicable MAIN OUTCOME MEASURES: The BPD-MS item banks.

RESULTS

BPD item pools were developed and refined using literature reviews, qualitative data from focus groups, and cognitive debriefing of persons with SCI and professional caregivers. The item banks then underwent expert review, reading level assessment, and translatability review prior to field testing. The items pools consisted of 180 unique questions (items). Exploratory and confirmatory factor analyses, item response theory modeling, and differential item function investigations resulted in item banks that included a total of 150 items: 75 describing the effect of autonomic dysreflexia on HRQOL, 55 describing the effect of low blood pressure (LBP) on HRQOL, and 20 describing the effect of LBP on daily activities. In addition, 10-item short forms were constructed based on item response theory-derived item information values and the clinical relevance of item content.

CONCLUSIONS

The new BPD-MS item banks and corresponding 10-item short forms were developed using established rigorous measurement development standards, which represents the first BPD-specific patient-reported outcomes measurement system unique for use in the SCI population.

Spinal Cord Injury-Functional Index/Capacity: Responsiveness to Change Over Time

OBJECTIVE

To establish responsiveness of 3 Spinal Cord Injury-Functional Index/Capacity (SCI-FI/C) item banks in the first year after spinal cord injury (SCI).

DESIGN

Longitudinal patient-reported outcomes assessment replicated through secondary analysis of an independent data set.

SETTING

A total of 8 SCI Model Systems rehabilitation hospitals in the United States.

PARTICIPANTS

Study 1 participants included 184 adults with recent (≤4 months) traumatic SCI and 221 community-dwelling adults (>1 year post injury) (N=405). Study 2 participants were 418 individuals with recent SCI (≤4 months) (N=418).

INTERVENTIONS

In study 1, SCI-FI/C computer adaptive tests were presented in a standardized interview format either in person or by phone call at baseline and 6-month follow-up. Responsiveness was examined by comparing 6-month changes in SCI-FI scores within and across samples (recently injured vs community-dwelling) because only the recent injury sample was expected to exhibit change over time. Effect sizes were also computed. In study 2, the study 1 results were cross-validated in a second sample with recent SCI 1 year after baseline measurement. Study 2 also compared the SCI-FI/C measures' responsiveness to that of the Self-reported Functional Measure (SRFM) and stratified results by injury diagnosis and completeness.

MAIN OUTCOME MEASURES

The SCI-FI Basic Mobility/C, Self-care/C and Fine Motor/C item banks (study 1 and study 2); Self-reported Functional Measure SRFM (study 2 only).

RESULTS

In study 1, changes in SCI-FI/C scores between baseline and 6-month follow-up were statistically significant (P<.01) for recently injured individuals. SCI-FI Basic Mobility/C, Self-care/C, and Fine Motor/C item banks demonstrated small to medium effect sizes in the recently injured sample. In the community-dwelling sample, all SCI-FI/C effects were negligible (ie, effect size<0.08). Study 2 results were similar to study 1. As expected, SCI-FI Basic Mobility/C and Self-care/C were responsive to change for all individuals in study 2, whereas the SCI-FI Fine Motor/C was responsive only for individuals with tetraplegia and incomplete paraplegia. The SRFM demonstrated a medium effect size for responsiveness (effect size=0.65).

CONCLUSIONS

The SCI-FI Basic Mobility/C and Self-care/C banks demonstrate adequate sensitivity to change at 6 months and 1 year for all individuals with SCI, while the SCI-FI/C Fine Motor item bank is sensitive to change in individuals with tetraplegia or incomplete paraplegia. All SCI-FI/C banks demonstrate stability in a sample not expected to change. Results provide support for the use of these measures for research or clinical use.

Physical Function Recovery Trajectories following Spinal Cord Injury

OBJECTIVE

Explore trajectories of functional recovery that occur during the first two years after spinal cord injury (SCI).

DESIGN

Observational cohort study.

SETTING

Eight SCI Model System sites.

PARTICIPANTS

479 adults with SCI completed four Spinal Cord Injury-Functional Index (SCI-FI) item banks within 4 months of injury and again at 2 weeks, 3, 6, 12, and 24 months following baseline assessment.

INTERVENTION

None.

MAIN OUTCOME MEASURES

SCI-FI Basic Mobility/Capacity (C), Fine Motor Function/C, Self-Care/C, and Wheelchair Mobility/Assistive Technology (AT) item banks.

RESULTS

Growth mixture modeling was used to identify groups with similar trajectory patterns. For the Basic Mobility/C and Wheelchair Mobility/AT domains, models specifying 2 trajectory groups were selected. For both domains, a majority class exhibited average functional levels and gradual improvement, primarily in the first six months. A smaller group of individuals made gradual improvements but had greater initial functional limitations. The Self Care/C domain exhibited a similar pattern; however, a third, small class emerged that exhibited substantial improvement in the first six months. Finally, for individuals with tetraplegia, trajectories of Fine Motor Function/C scores followed two patterns, with individuals reporting generally low initial scores and then making either modest or large improvements. In individual growth curve models, injury/demographic factors predicted initial functional levels but less so with regard to rates of recovery.

CONCLUSIONS

Trajectories of functional recovery followed a small number of change patterns, though variation around these patterns emerged. During the first two years after initial hospitalization, SCI-FI scores showed modest improvements; however, substantial improvements were noted for a small number of individuals with severe limitations in fine motor and self-care function. Future studies should further explore the personal, medical, and environmental characteristics that influence functional trajectories during these first two years and beyond.

Understanding Persons With Disabilities’ Reasons for Not Seeking Employment

Unemployment is common for persons with disabilities but little is known about the different reasons why people with disabilities may not be seeking employment. This study identified the reasons that people living with disabilities report for not seeking employment, from the 2015 Kessler Foundation National Employment and Disability Survey (KFNEDS) and variation of reasons by demographic, socioeconomic, and disability characteristics. We conducted a content analysis of responses to an open-ended question on the KFNEDS. The analytic sample ( n = 1,254) included adults (ages 18–64) living with disabilities, who self-identified as either unemployed or not seeking employment. Team coding used a hybrid inductive/deductive approach to identify nine meaningful reasons why people with disabilities may not seek employment. Overall, medical conditions, functional limitations, or their disability were more likely to be reported as reasons for not seeking work, rather than situational reasons associated with workplace engagement, such as “lack of job opportunities.” Bivariate comparisons of codes across demographic, socioeconomic, and disability characteristics noted variability in reasons reported by respondents by sex, race/ethnicity, age, household income, and disability. These findings provide an understanding of diverse reasons for not seeking employment, which can inform programs and policies that promote labor force participation of people with disabilities.

Spinal Cord Injury Veterans' Disability Benefits, Outcomes, and Health Care Utilization Patterns: Protocol for a Qualitative Study

BACKGROUND

An estimated 42,000 people currently living with chronic spinal cord injury (SCI) are veterans. SCI was a common combat-related injury in the World Wars and Vietnam era and now affects more than 11% of military personnel injured in Operation Iraqi Freedom and Operation Enduring Freedom. The Veterans Benefits Administration primarily offers financial compensation for disabilities sustained or re-aggravated during military service, called service-connected disability compensation. With the overwhelming cost of living with an SCI, this monthly financial compensation can provide service-connected veterans and their families with access to additional supportive resources (eg, assistive devices and personal aide) and maintain their quality of life (QOL). Little is known about personal, health, functional, and QOL outcomes associated with service-connected and nonservice-connected status for veterans living with an SCI.

OBJECTIVE

The aim of this study is to compare the ways in which Veterans Affairs' (VA) service-connected and nonservice-connected status may be associated with health and functional outcomes, choice of health care provider, and overall QOL for veterans living with an SCI and their caregivers.

METHODS

This cross-sectional qualitative study will gather data using retrospective chart reviews, semistructured interviews, and focus groups. After obtaining institutional review board (IRB) approval, purposeful sampling techniques will be used to recruit and enroll the following key stakeholders: veterans living with an SCI, family caregivers, and SCI health care providers. Concurrent data collection will take place at 2 sites: Veterans Administration New Jersey Healthcare System and Northern New Jersey Spinal Cord Injury System.

RESULTS

This study was funded in July 2015. IRB approval was obtained by November 2016 at both sites. Enrollment and data collection for phase 1 to phase 4 are complete. A total of 69 veterans, 18 caregivers, and 19 SCI clinicians enrolled in the study. Data analyses for these phases are underway. In phase 5, the follow-up focus group activities are scheduled. The final results are expected by the end of 2019.

CONCLUSIONS

The factors that contribute to veterans living with SCI seeking and not seeking VA disability compensation benefits are not well understood in rehabilitation research. Triangulation of these data sources will allow us to compare, contrast, and integrate the results, which can be used to develop clinical guidelines, caregiver training, and patient education programs.

A Cross-Sectional Study to Investigate the Effects of Perceived Discrimination in the Health Care Setting on Pain and Depressive Symptoms in Wheelchair Users With Spinal Cord Injury

OBJECTIVES

In a sample of wheelchair users with spinal cord injury (SCI), the objectives were to investigate which participant characteristics are associated with greater perceived discrimination in the health care setting, and how such discrimination relates to health outcomes of pain and depressive symptoms.

DESIGN

Survey, cross-sectional.

SETTING

Spinal Cord Injury Model Systems (SCIMS) Center.

PARTICIPANTS

Full-time wheelchair users with SCI from 9 SCIMS centers (N=410), with data collected between 2011 and 2016.

INTERVENTIONS

N/A.

MAIN OUTCOMES

A 7-item questionnaire inquiring about perceived discrimination by hospital staff, self-reported pain severity over the past month using a 0-10 Numeric Rating Scale, and depressive symptoms using the 2-question Patient Health Questionnaire screener.

RESULTS

Participants who were black or from the lowest income group were more likely to report experiencing more discrimination than those who were white or from the highest income group, respectively (incidence rate ratio=2.2-2.6, P<.01). Those who reported more perceived discrimination had greater risk of severe pain compared to no pain (relative risk [RR]=1.11; 95% confidence interval [95% CI], 1.01-1.23; P<.05), mild depressive symptoms (RR=1.09; 95% CI, 1.02-1.17; P<.05), and severe depressive symptoms (RR=1.12; 95% CI, 1.04-1.21; P<.05) compared to no symptoms.

CONCLUSIONS

Wheelchair users with SCI who were from more disadvantaged groups (black, lower income levels) reported experiencing more discrimination in their health care setting. Furthermore, those who reported more discrimination were more likely to report worse mental and physical health outcomes. Attempts to reduce discrimination in health care settings may lead to better outcomes for people with SCI. These observations were correlational and not causal; a prospective analysis is necessary to prove causation. Future investigations should further explore the effect of discrimination on the many facets of living with an SCI.

Informal caregivers' burden and stress in caring for stroke survivors with spatial neglect: an exploratory mixed-method study

BACKGROUND

Spatial neglect prolongs stroke survivors' recovery to independence. However, little is known about the impact of spatial neglect on caregivers of stroke survivors.

OBJECTIVE

To explore the factors associated with burden and stress among informal caregivers of stroke survivors with spatial neglect.

METHODS

Following the previous study of 108 stroke survivors, we reached 24 stroke survivors' caregivers, and 20 caregivers (age: M±SD=56.9±12.7 years; 12 females) completed the study. 10 survivors had symptoms of spatial neglect, and 10 did not (i.e., SN+ or SN-, respectively) at the time when discharged from inpatient rehabilitation, which was 9.3±6.2 months before the present study. Via a semi-structured telephone interview, we assessed caregivers' burden and stress qualitatively and quantitatively.

RESULTS

No difference was observed across caregiver groups in cognitive function, depressive mood, or community mobility. In comparison, caregivers of the SN+ group allocated more time to care, controlling for survivors' disability (adjusted effective size d = 1.80). Their self-perceived burden and stress were more severe than the other group (adjusted d = .99). Qualitative analysis indicated caregivers of the SN+ group were more likely to describe economic stressors and undesirable changes in career and vacation planning. While 80% of participants preferred their care recipients to receive additional motor or mobility therapy, caregivers of the SN+ group were more likely to suggest additional therapy for cognitive impairment.

CONCLUSIONS

This exploratory study suggests that spatial neglect may heighten caregivers' burden and stress levels. Future studies with a large sample size are required.

Differential item functioning due to cognitive status does not impact depressive symptom measures in four heterogeneous samples of older adults

OBJECTIVE

The objective of this study is to determine whether differential item functioning (DIF) due to cognitive status impacted three depressive symptoms measures commonly used with older adults.

METHODS

Differential item functioning in depressive symptoms was assessed among participants (N = 3558) taking part in four longitudinal studies of cognitive aging, using the Geriatric Depression Scale, the Montgomery-Åsberg Depression Rating Scale, and the Center for Epidemiologic Studies Depression Scale. Participants were grouped by cognitive status using a general cognitive performance score derived from each study's neuropsychological battery and linked to a national average using a population-based survey representative of the US population. The Clinical Dementia Rating score was used as an alternate grouping variable in three of the studies.

RESULTS

Although statistically significant DIF based on cognitive status was found for some depressive symptom items (e.g., items related to memory complaints, appetite loss, lack of energy, and mood), the effect of item bias on the total score for each scale was negligible.

CONCLUSIONS

The depressive symptoms scales in these four studies measured depression in the same way, regardless of cognitive status. This may reduce concerns about using these depression measures in cognitive aging research, as relationships between depression and cognitive decline are unlikely to have been due to item bias, at least in the ways that were measured in the datasets we considered.

Racial and ethnic disparities in functioning at discharge and follow-up among patients with motor complete spinal cord injury

OBJECTIVE

To examine racial and ethnic differences in self-care and mobility outcomes for persons with a motor complete, traumatic spinal cord injury (SCI) at discharge and 1-year follow-up.

DESIGN

Retrospective cohort study.

SETTING

Sixteen rehabilitation centers contributing to the Spinal Cord Injury Model Systems (SCIMS) database.

PARTICIPANTS

Adults with traumatic, motor complete SCI (N=1766; American Spinal Injury Association Impairment Scale grade A or B) enrolled in the SCIMS between 2000 and 2011. Selected cases had complete self-reported data on race and ethnicity (non-Hispanic white, non-Hispanic black, or Hispanic) and motor FIM scores assessed at inpatient rehabilitation admission, discharge, and 1-year follow-up.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Functional outcomes were measured by FIM self-care and mobility scores on a 1 to 7 FIM scale, at discharge and 1-year follow-up.

RESULTS

Multiple regression models stratified by neurologic category and adjusted for sociodemographic and injury characteristics assessed racial and ethnic group differences in FIM self-care and mobility change scores at discharge and 1-year follow-up. At discharge, non-Hispanic black participants with tetraplegia and paraplegia had significantly poorer gains in FIM self-care and mobility scores relative to non-Hispanic white and Hispanic participants. At 1-year follow-up, similar FIM self-care and mobility change scores were found across racial and ethnic groups within each neurologic category.

CONCLUSIONS

Non-Hispanic white and Hispanic participants had comparatively more improvement in self-care and mobility during inpatient rehabilitation compared with non-Hispanic black participants. At 1-year follow-up, no differences in self-care and mobility outcomes were observed across racial and ethnic groups. Additional research is needed to identify potential modifiable factors that may contribute to racially and ethnically different patterns of functional outcomes observed during inpatient rehabilitation.

The association of race, cultural factors, and health-related quality of life in persons with spinal cord injury

OBJECTIVE

To examine the association of race and cultural factors with quality-of-life factors (participation, life satisfaction, perceived health status) in people with spinal cord injury (SCI).

DESIGN

Cross-sectional multisite study using structured questionnaires.

SETTING

Six National SCI Model Systems centers.

PARTICIPANTS

People with SCI (N=275; age ≥16y; SCI with discernable neurologic impairments; used power or manual wheelchair for >1y as primary means of mobility; nonambulatory except for exercise purposes).

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Participation (Craig Handicap Assessment and Reporting Technique Short Form); satisfaction (Satisfaction With Life Scale); and perceived health status (2 items from 36-Item Short Form Health Survey).

RESULTS

African American (n=96) with SCI reported more experiences of discrimination in health care, greater perceived racism, more health care system distrust, and lower health literacy than whites (n=156; P range, <.001-<.05). Participants who reported experiencing more discrimination in health care reported better occupational functioning (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.07-2.09; P<.05). Those who perceived more racism in health care settings reported better occupational functioning (OR, 1.65; 95% CI, 1.12-2.43; P<.05) and greater perceived health (β=.36; 95% CI, .05-.68; P<.05). Those who reported more distrust in the health care system reported better current health compared with 1 year ago (β=.38; 95% CI, .06-.69; P<.05). Those who reported better communication with their health care provider reported higher levels of mobility (OR, 1.5; 95% CI, 1.05-2.13; P<.05) and better general health (β=.27; 95% CI, .01-.53; P<.05).

CONCLUSIONS

In this cross-sectional study of people with SCI, higher levels of perceived discrimination and racism and better communication with health care providers were associated with an increase in participation and functioning and improvements in perceptions of well-being. These associations are different from those reported in other study populations and warrant confirmation in future prospective studies.

Vulnerable Groups Living with Spinal Cord Injury

There is considerable variation in rehabilitation outcomes within the population of spinal cord-injured individuals across racial and socioeconomic groups. This suggests that the long-term health following spinal cord injury (SCI) is determined, at least in part, by group differences in exposure to advantages and disadvantages among persons living in the community. This article conceptualizes the nature of vulnerability and how increased vulnerability leads to disparities in SCI outcomes. Demographic, socioeconomic, and geographic determinants of adverse outcomes among vulnerable groups are discussed. Finally, a research model that outlines potential processes that elicit vulnerability following SCI and clinical implications is reviewed.

Family physicians' barriers to cancer screening in extremely obese patients

Extremely obese women are less likely than nonobese women to receive breast and cervical cancer screening examinations. Reasons for this disparity are unclear and may stem from patient and/or physician barriers. This sequential mixed-methods study used individual in-depth interviews of 15 family physicians followed by a mail survey of 255 family physicians (53% response rate) to understand the barriers they faced in performing cancer screening examinations in extremely obese women. Barriers fell into three main areas: (i) difficulty doing pelvic and breast exams; (ii) inadequate equipment; and (iii) challenges overcoming patient barriers and refusal. This led some physicians to avoid performing breast and pelvic examinations on extremely obese women. Having more knowledge about specific examination techniques was associated with less difficulty in palpating lumps on breast and pelvic examinations (P < 0.005). Physicians perceived that embarrassment, aversion to undressing, and avoidance of discussions related to their weight were the most frequent barriers extremely obese women had with getting physical examinations. Educating and/or motivating patients and addressing fears were strategies used most frequently when patients refused mammograms or Pap smears. Interventions focusing on physician barriers, such as educating them on specific examination techniques, obtaining adequate equipment and supplies, and providing resources to assist physicians in dealing with patient barriers and refusal, may be fruitful in increasing cancer screening rates in extremely obese patients. Future research studies testing the effectiveness of these strategies are needed to improve cancer outcomes in this high-risk population.

Older home-care patients' preferred approaches to depression care: a pilot study

The purpose of this pilot study was to explore the approaches to depression care preferred by older home-care patients and examine characteristics associated with those preferences. Twenty-eight long-term home-care patients, ages 62 to 95, were interviewed. Patients ranked their depression care preferences and provided rationale for their responses. Results indicated prayer was preferred by the highest percentage of patients (50%). Comparing patients with and without depression experience, prayer was preferred by the latter group. The results highlight the importance of addressing patient preferences during care planning to improve participation in geriatric depression care management.

Late-life depression among black and white elderly homecare patients

OBJECTIVE

The authors compared the prevalence of major depressive disorder (MDD) and the prescription rates of antidepressant medication, by race, among frail, older homecare patients.

METHODS

A random sample of 56 black and 458 white newly admitted homecare patients age 65 and over was assessed for MDD with structured interviews and medical records, and antidepressant prescription rates were tallied.

RESULTS

The prevalence of MDD did not differ significantly across racial groups. Only 16.7% of black patients and 32.0% of white patients were prescribed antidepressant medication.

CONCLUSIONS

Prevalence of MDD was similar among black and white elderly homecare patients. In both groups, depression is undertreated and contributes to the burden of this frail, older patient group.
