Test-Retest Reliability of the Electronic Instrumental activities of daily living Satisfaction Assessment (EISA): A Cohort Study

IMPORTANCE

Currently, no self-report instruments exist for assessing satisfaction with performing instrumental activities of daily living and occupations for people with disabilities using internet-connected assistive devices like accessible smartphones, tablets, laptops, and apps.

OBJECTIVE

To assess the test-retest reliability and internal consistency of the Electronic Instrumental activities of daily living Satisfaction Assessment (EISA) self-report outcome tool.

DESIGN

Repeated-measures cohort study with a time frame of 7 to 21 days.

SETTING

Multicity online recruitment at assistive technology clinics, nongovernmental organizations, advocacy and peer support groups for people with disabilities, and higher education institutions.

PARTICIPANTS

Eighty-four participants with disabilities, age 18 yr or older, with a mean age of 43.3 yr (range = 19-75 yr), and 57% female.

INTERVENTION

Not applicable.

OUTCOMES AND MEASURES

The a priori study hypotheses were that the EISA test-retest reliability scores would be above the minimum acceptable level (Rs > .80) and that internal consistency would be good (Cronbach's α = .70-.90).

RESULTS

On the basis of the study data, the EISA, Version 1.0, demonstrated good test-retest reliability (Rs = .81) and excellent internal consistency (Cronbach's α = .88).

CONCLUSIONS AND RELEVANCE

The results of the test-retest reliability and internal consistency analyses provide good support for the EISA to be used in clinical settings. What This Article Adds: This article documents the reliability and internal consistency of, to our knowledge, the first-ever self-report instrument for assessing satisfaction with performance of everyday occupations for people with disabilities using internet-connected assistive devices such as smartphones, tablets, laptops, and apps.

A vocational rehabilitation partnership to provide transition services to young adults with neurodevelopmental disabilities: The cognitive skills enhancement program

BACKGROUND: There is an urgent need for services that support a successful transition to postsecondary education and employment for young adults with neurodevelopmental and cognitive disabilities (e.g. autism spectrum disorder, attention-deficit/hyperactivity disorder, traumatic brain injury). OBJECTIVE: The purpose of this expository article is to describe the Cognitive Skills Enhancement Program (CSEP), a comprehensive clinical program designed for young adults with neurodevelopmental and cognitive disabilities transitioning to postsecondary education. METHODS: CSEP was developed through a community-academic partnership between a university and a state vocational rehabilitation program. Young adult participants complete programming that addresses four primary clinical targets: (1) emotion regulation, (2) social skills, (3) work readiness, and (4) community participation with the overall goal to increase awareness and promote successful employment outcomes while they transition to post-secondary education. RESULTS: To date, CSEP has supported 18 years of sustained programming and clinical services to 621 young adults with neurodevelopmental and cognitive disabilities. CONCLUSION: This partnership model allows for flexible responses to participant needs, implementation barriers, and advances in evidence-based practices. CSEP meets the needs of diverse stakeholders (e.g. state vocational rehabilitation, post-secondary training facilities, participants, universities) while providing high-quality and sustainable programming. Future directions include examining the clinical efficacy of current CSEP programming.

Cut points and sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in adults with traumatic brain injury

BACKGROUND

Community participation is an important outcome of rehabilitation following traumatic brain injury. Yet, few measures assess inclusion and belonging (enfranchisement) as a dimension of community participation. The Enfranchisement scale of the Community Participation Indicators addresses this need. However, research on its psychometric properties is lacking.

OBJECTIVE

To examine cut points and sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in adults with traumatic brain injury.

DESIGN

This was a repeated measures study with assessments administered twice (3 months apart).

SETTING

Assessments were administered either over the phone, virtually (Zoom), or in person at the participant's home.

PARTICIPANTS

A total of 44 participants from community settings who had either experienced a traumatic brain injury within the previous year or were receiving rehabilitation interventions were recruited.

MAIN OUTCOME MEASURE

The Enfranchisement scale has two subscales: the Control subscale (range: 13-65) and the Importance subscale (range: 14-70). On both subscales, lower scores indicate better enfranchisement.

METHODS

The software SAS PROC Logistic and the macro %ROCPlot were used to examine cut points at varying levels of sensitivity and specificity. The area under the receiver operating characteristics curve was calculated to determine overall classification accuracy. Minimum detectable change and minimal clinically important difference were also calculated.

RESULTS

For the Control subscale, a cut point of 44 (area under the curve = .75), a minimum detectable change of 8, and a minimal clinically important difference of 5 were found. For the Importance subscale, a cut point of 39 (area under the curve = .81), a minimum detectable change of 8, and a minimal clinically important difference of 5 were found.

CONCLUSIONS

The cut points resulted in good classification accuracy, providing support for their reliability. The results provided evidence that both subscales are sensitive to change in adults with brain injury.

Detecting change in community participation with the Enfranchisement scale of the community participation indicators

OBJECTIVE

This study determined the sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in people with stroke.

DATA SOURCES

We analyzed data from two studies of participants with stroke: an intervention study and an observational study.

MAIN MEASURES

The Enfranchisement Scale contains two subscales: the Importance subscale (feeling valued by and contributing to the community; range: 14-70) and the Control subscale (choice and control: range: 13-64).

DATA ANALYSIS

Assessments were administered 6 months apart. We calculated minimum detectable change and minimal clinically important difference.

RESULTS

The Control subscale analysis included 121 participants with a mean age of 61.2 and mild-moderate disability (Functional Independence Measure, mean = 97.9, SD = 24.7). On the Control subscale, participants had a mean baseline score of 51.4 (SD = 10.4), and little mean change (1.3) but with large variation in change scores (SD = 11.5). We found a minimum detectable change of 9 and a minimum clinically important difference of 6. The Importance subscale analysis included 116 participants with a mean age of 60.7 and mild-moderate disability (Functional Independence Measure, mean = 98.9, SD = 24.5). On the Importance subscale, participants had a mean baseline score of 44.1 (SD = 12.7), and again demonstrated little mean change (1.08) but with large variation in change scores (SD = 12.6). We found a minimum detectable change of 11 and a minimum clinically important difference 7.

CONCLUSIONS

The Control subscale required 9 points of change, and the Importance subscale required 11 points of change, to achieve statistically and clinically meaningful changes, suggesting adequate sensitivity to change.

Construct validity of the enfranchisement scale of the community participation indicators

OBJECTIVE

This study examined the construct validity of the Enfranchisement scale of the Community Participation Indicators.

DESIGN

We conducted a secondary analysis of data collected in a cross-sectional study of rehabilitation outcomes.

SUBJECTS

The parent study included 604 community-dwelling adults with chronic traumatic brain injury, stroke, or spinal cord injury. The sample had a mean age of 64.1 years, was two-thirds male, and included a high proportion of racial minorities (n = 250, 41.4%).

MAIN MEASURES

The Enfranchisement scale contains two subscales: the Control subscale and the Importance subscale. We examined correlations between each Enfranchisement subscale and measures of participation, environment, and impairments. The current analyses included cases with at least 80% of items completed on each subscale (Control subscale: n = 391; Importance subscale: n = 219). Missing values were imputed using multiple imputation.

RESULTS

The sample demonstrated high scores, indicating poor enfranchisement (Control subscale: M = 51.7; Importance subscale: M = 43.0). Both subscales were most strongly associated with measures of participation (Control subscale: r = 0.56; Importance subscale: r = 0.52), and least strongly associated with measures of cognition (Control subscale: r = 0.03; Importance subscale: r = 0.03). The Importance subscale was closely associated with depression (r = 0.54), and systems, services, and policies (r = 0.50). Both subscales were associated with social attitudes (Control subscale: r = 0.44; Importance subscale: r = 0.44) and social support (Control subscale: r = 0.49; Importance subscale: r = 0.41).

CONCLUSIONS

We found evidence of convergent validity between the Enfranchisement scale and measures of participation, and discriminant validity between the Enfranchisement scale and measures of disability-related impairments. The analyses also revealed the importance of the environment to enfranchisement outcomes.

Activating Behavior to Reduce Sedentary Behavior After Stroke: A Nonrandomized Pilot Feasibility Study

Importance: Reducing poststroke sedentary behavior is important for reducing recurrent stroke risk, yet interventions to achieve this are scant.

Objective: To assess the feasibility of, and estimate change in sedentary behavior over time associated with, a behavioral intervention.

Design: Single-arm delayed baseline with postintervention and 8-wk follow-up assessment.

Setting: Community based.

Participants: Ambulatory, community-dwelling people with chronic stroke and reported ≥6 hr daily sitting time (N = 21).

Intervention: Activating Behavior for Lasting Engagement (ABLE) was delivered by an occupational therapist 3×/wk for 4 wk. ABLE involves activity monitoring, activity scheduling, self-assessment, and collaborative problem solving.

Outcomes and Measures: Feasibility (participant safety, adherence, satisfaction, and reliable intervention delivery) was assessed against preestablished benchmarks. Changes over time in sedentary behavior (assessed with an ActivPAL micro3 device) and participation (Stroke Impact Scale–Participation subscale) were described.

Results: ABLE was safe (0 serious adverse events), adhered to (11.95 sessions/participant), and reliably delivered (90.00%–97.50% adherence). Participant satisfaction was unmet (Client Satisfaction Questionnaire–8, M = 28.75, SD = 3.84). ABLE was associated with a mean group reduction in prolonged sitting of 54.95 min (SD = 81.10) at postintervention and 14.08 (SD = 58.95) at follow-up. ABLE was associated with a negligible mean group increase over time in participation at postintervention (M = 1.48%, SD = 8.52) and follow-up (M = 1.33%, SD = 15.38).

Conclusions and Relevance: The ABLE intervention is feasible and may be associated with within-group reduction in sedentary behavior over time. Further refinement is indicated.

What This Article Adds: The ABLE intervention uses engagement in meaningful daily activities to reduce sedentary behavior after stroke. These findings suggest that ABLE can be delivered safely and consistently. Further research is required to enhance participant satisfaction and determine the effects of ABLE on stroke survivors’ sedentary behavior.

The impact of frailty in an endocarditis cohort: association with length of stay and mortality

Introduction

Predictors of poor outcome are well established in Endocarditis (IE). “Frailty” refers to a syndrome of physiological decline associated with adverse health outcomes. Gilbert et al.(Lancet, 2018) developed a Hospital Frailty Risk Score (HFRS) that predicts 30-day mortality and length of stay (LOS).

Aim

Identify impact of an abbreviated HFRS (aHFRS) on in-hospital survival and LOS in IE given high morbidity and mortality.

Methods

Retrospective analysis of prospectively collected cases (Jan 2018–date). aHFRS score was calculated with key IE, cardiac, respiratory, oncology & frailty diagnoses. Univariate regression was applied overall and in key “cohorts” (native & prosthetic IE, medical & surgical management) for survival and LOS.

Results

Of 334 cases, LOS data were available in 317; mean age 57.8y (range 17–91, male 74%). Table 1 describes key cohorts. Mortality was 10.1% (medical, 11.9%; surgical, 8.3%). Mean LOS was 31.2 days (range 0–224).

Mean aHFRS was 5.38diagnoses (SD 2.61, range 0–14); 1.65 pre-IE and 3.73 attributed to IE alone, consistent across cohorts. Regression analyses highlight increasing LOS with increasing aHFRS (r2=0.06, Figure 1). Table 1 summarises the modest impact of aHFRS on LOS, and a trend to worse outcome in medical management (r2=0.02).

Discussion

Higher aHFRS is associated with longer LOS and a trend to higher mortality in medically managed IE. IE itself is associated with a number of frailty diagnoses. To improve outlook and provide holistic care, the IE Team may need to include experts in frailty. Satisfactory outcomes may require intensive post-IE rehabilitation.

Domains and dimensions of community participation following traumatic brain injury

PRIMARY OBJECTIVE

To examine patterns of community participation, as well as the relationship among community participation outcomes and time since injury, impairments, environmental factors, and enfranchisement in adults with traumatic brain injury (TBI).

RESEARCH DESIGN

Cross-sectional study of a sample of 61 adults with TBI.

METHODS AND PROCEDURES

We administered the Participation Measure- 3 Domains 4 Dimensions to examine community participation in the three domains (productivity, community activities, and social participation) using four dimensions (diversity of activities, frequency, difficulty, and desire for change).

MAIN RESULTS AND OUTCOMES

All dimensions of community participation seem to be impaired following TBI, as evidenced by scores in the lower half of the available range. Most impaired was social participation (frequency: M = 10.0, SD = 3.4, possible range 0-24; difficulty: M=  11.3, SD = 3.2, possible range 4-16). Correlational analyses revealed that depression (r = 0.51), environmental factors (r = 0.51), and enfranchisement (r = 0.42), seem to play an important role in community participation outcomes, and may be potential targets for intervention. Results did not vary based on time since injury.

CONCLUSION

Our results suggest that depression, environmental factors, and enfranchisement may be important considerations for future interventions aiming to promote management of identified barriers.

Genetic investigation of equine recurrent uveitis in Appaloosa horses

Equine recurrent uveitis (ERU) is characterized by intraocular inflammation that often leads to blindness in horses. Appaloosas are more likely than any other breed to develop insidious ERU, distinguished by low-grade chronic intraocular inflammation, suggesting a genetic predisposition. Appaloosas are known for their white coat spotting patterns caused by the leopard complex spotting allele (LP) and the modifier PATN1. A marker linked to LP on ECA1 and markers near MHC on ECA20 were previously associated with increased ERU risk. This study aims to further investigate these loci and identify additional genetic risk factors. A GWAS was performed using the Illumina Equine SNP70 BeadChip in 91 horses. Additive mixed model approaches were used to correct for relatedness. Although they do not reach a strict Bonferroni genome-wide significance threshold, two SNPs on ECA1 and one SNP each on ECA12 and ECA29 were among the highest ranking SNPs and thus warranted further analysis (P = 1.20 × 10^-5 , P = 5.91 × 10^-6 , P = 4.91 × 10^-5 , P = 6.46 × 10^-5 ). In a second cohort (n = 98), only an association with the LP allele on ECA1 was replicated (P = 5.33 × 10^-5 ). Modeling disease risk with LP, age and additional depigmentation factors (PATN1 genotype and extent of roaning) supports an additive role for LP and suggests an additive role for PATN1. Genotyping for LP and PATN1 may help predict ERU risk (AUC = 0.83). The functional role of LP and PATN1 in ERU development requires further investigation. Testing samples across breeds with leopard complex spotting patterns and a denser set of markers is warranted to further refine the genetic components of ERU.

Key drivers of financial performance of insurers in the Affordable Care Act market exchange

While most publicly-traded insurers have experienced losses and exited the Affordable Care Act individual insurance market exchange, insurers specializing in Medicaid managed care have been profitable in this market. Accessing individual market data, this study compares the financial performance of 20 state insurers owned by two publicly-traded companies that historically focused on insuring Medicaid members compared to 40 insurers owned by other publicly-traded companies. Medicaid-focused insurers incurred a significantly lower medical loss ratio of 83.3% compared to the medical loss ratio of 93.7% of other publicly-traded insurers, and they earned a significantly higher profit margin of 4.6% compared to the operating loss of 6.5% incurred by other publicly-traded insurers. This superior financial performance of Medicaid-focused insurers could be due to one or a combination of: their care management experience with the Medicaid population, other cost reducing strategies such as provider contracting, or the enrollment of a healthier than average population.

P2764Medical management of Staphylococcus aureus infective endocarditis: unexpectedly favourable outcomes in an aggressive disease

Introduction

Early surgical intervention (ESI) for infective endocarditis (IE) is associated with improved outcomes. Staphylococcus aureus endocarditis (SAE) is associated with particularly high rates of tissue destruction, morbidity and mortality. However, the question as to whether ESI is mandated in all SAE continues to be debated, in both native (NVE) and prosthetic (PVE) endocarditis.

Methods

Retrospective review of all IE cases presenting to our institution from October 2015 to January 2019. IE was diagnosed following imaging and microbiological protocols as per ESC guidance, and data were extracted for those with SAE. Patients with isolated cardiac implantable electronic device IE or bacteraemia secondary to indwelling long-term venous catheter infection were excluded (non-valvular IE).

Results

Valvular IE was diagnosed in 411 patients overall; NVE in 286 (69.6%) and PVE in 125 (30.4%). S aureus was isolated in 111 patients (28.1%), of whom 5 had a Methicillin-resistant strain. SAE was confirmed in a similar proportion of NVE and PVE cases [83/111 (74.8%) and 28/111 (25.2%), respectively]. Surgical intervention was mandated in 35/83 with NVE (42.2%) and 11/28 (39.3%) with PVE, lower than in our overall cohort (55.9% and 48.8%, respectively).

In-hospital SAE mortality was 16.2% overall (18.4% medical vs 13.0% surgical), and contributes a significant proportion to overall mortality (29% to medical & 26% to surgical mortality). Figure 1 identifies the cause of death per mode of treatment, highlighting the aggressive nature of S aureus infection (abscess, disseminated infection and septic shock; n=8), the importance of advanced non-cardiac comorbidity precluding intervention (n=3) and ongoing intravenous drug use in those with PVE (n=4). However, medical management was successful in 57.8% (38/83) of NVE and 60.7% (17/28) of PVE cases, both in hospital and to a minimum follow-up of 3-months.

Conclusion

Staphylococcus aureus is virulent and highly pathogenic, driving severe sepsis and advanced tissue destruction in SAE. Despite this, medical management can be successful when following international guidance, but requires co-ordinated care driven by a multidisciplinary IE team at a cardiothoracic centre.

How a diverse research ecosystem has generated new rehabilitation technologies: Review of NIDILRR's Rehabilitation Engineering Research Centers

Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a "total approach to rehabilitation", combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970's, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program.

A novel tool for naturalistic assessment of behavioural dysregulation after traumatic brain injury: A pilot study

OBJECTIVE

This study aimed to develop a novel tool for measuring behavioural dysregulation in adults with traumatic brain injury (TBI) using objective data sources and real-world application and provide preliminary evidence for its psychometric properties.

RESEARCH DESIGN

Fourteen adults with TBI receiving services at a local brain injury rehabilitation programme completed multiple assessments of behaviour and followed by a series of challenging problem-solving tasks while being video recorded. Trained clinicians completed post-hoc behavioural assessments using the behavioural dysregulation ratings scale, and behavioural event data were then extracted for comparison with self-report measures.

RESULTS

Subject matter experts in neurorehabilitation were in 100% agreement that preliminarily, the new tool measured the construct of behavioural dysregulation. Construct validity was established through strong convergence with 'like' measures and weak correlation with 'unlike' measures. Substantial inter-rater reliability was established between two trained clinician raters.

CONCLUSIONS

This study provides preliminary evidence supporting the use of a new precision measurement tool of behaviour in post-acute TBI that has the capability to be deployed naturalistically where deficits truly manifest. Future large-scaled confirmatory psychometric trials are warranted to further establish the utility of this new tool in rehabilitation research.

A Flexible and Integrated System for the Remote Acquisition of Neuropsychological Data in Stroke Research

BACKGROUND

Neuropsychological testing is a central aspect of stroke research because it provides critical information about the cognitive-behavioral status of stroke survivors, as well as the diagnosis and treatment of stroke-related disorders. Standard neuropsychological methods rely upon face-to-face interactions between a patient and researcher, which creates geographic and logistical barriers that impede research progress and treatment advances.

INTRODUCTION

To overcome these barriers, we created a flexible and integrated system for the remote acquisition of neuropsychological data (RAND). The system we developed has a secure architecture that permits collaborative videoconferencing. The system supports shared audiovisual feeds that can provide continuous virtual interaction between a participant and researcher throughout a testing session. Shared presentation and computing controls can be used to deliver auditory and visual test items adapted from standard face-to-face materials or execute computer-based assessments. Spoken and manual responses can be acquired, and the components of the session can be recorded for offline data analysis.

MATERIALS AND METHODS

To evaluate its feasibility, our RAND system was used to administer a speech-language test battery to 16 stroke survivors with a variety of communication, sensory, and motor impairments. The sessions were initiated virtually without prior face-to-face instruction in the RAND technology or test battery.

RESULTS

Neuropsychological data were successfully acquired from all participants, including those with limited technology experience, and those with a communication, sensory, or motor impairment. Furthermore, participants indicated a high level of satisfaction with the RAND system and the remote assessment that it permits.

CONCLUSIONS

The results indicate the feasibility of using the RAND system for virtual home-based neuropsychological assessment without prior face-to-face contact between a participant and researcher. Because our RAND system architecture uses off-the-shelf technology and software, it can be duplicated without specialized expertise or equipment. In sum, our RAND system offers a readily available and promising alternative to face-to-face neuropsychological assessment in stroke research.

Pilot feasibility of an mHealth system for conducting ecological momentary assessment of mood-related symptoms following traumatic brain injury

OBJECTIVE

This study assessed pilot feasibility and validity of a mobile health (mHealth) system for tracking mood-related symptoms after traumatic brain injury (TBI).

DESIGN

A prospective, repeated measures design was used to assess compliance with daily ecological momentary assessments (EMA) conducted via a smartphone application over an 8-week period.

METHODS

An mHealth system was developed specifically for individuals with TBI and utilized previously validated tools for depressive and anxiety symptoms (Patient Health Questionnaire-9, Generalized Anxiety Disorder-7). Feasibility was assessed in 20 community-dwelling adults with TBI via an assessment of compliance, satisfaction and usability of the smartphone applications. The authors also developed and implemented a clinical patient safety management mechanism for those endorsing suicidality.

RESULTS

Participants correctly completed 73.4% of all scheduled assessments, demonstrating good compliance. Daily assessments took <2 minutes to complete. Participants reported high satisfaction with smartphone applications (6.3 of 7) and found them easy to use (6.2 of 7). Comparison of assessments obtained via telephone-based interview and EMA demonstrated high correlations (r = 0.81-0.97), supporting the validity of conducting these assessments via smartphone application in this population.

CONCLUSIONS

EMA conducted via smartphone demonstrates initial feasibility among adults with TBI and presents numerous opportunities for long-term monitoring of mood-related symptoms in real-world settings.

Telerehabilitation and Clinical Applications: Research, Opportunities, and Challenges

Rehabilitation service providers in rural or underserved areas are often challenged in meeting the needs of their complex patients due to limited resources in their geographical area. Recruitment and retention of the rural clinical workforce are beset by the ongoing problems associated with limited continuing education opportunities, professional isolation, and the challenges inherent to coordinating rural community healthcare. People with disabilities who live in rural communities also face challenges accessing healthcare. Traveling long distances to a specialty clinic for necessary expertise is troublesome due to inadequate or unavailable transportation, disability specific limitations, and financial limitations. Distance and lack of access are just two threats to quality of care that now being addressed by the use of videoconferencing, information exchange, and other telecommunication technologies that facilitate telerehabilitation.This white paper illustrates and summarizes clinical and vocational applications of telerehabilitation. We provide definitions related to the fields of telemedicine, telehealth, and telerehabilitation, and consider the impetus for telerehabilitation. We review the telerehabilitation literature for assistive technology applications; pressure ulcer prevention; virtual reality applications; speech-language pathology applications; seating and wheeled mobility applications; vocational rehabilitation applications; and cost-effectiveness. We then discuss external telerehabilitation influencers, such as the positions of professional organizations. Finally, we summarize clinical and policy issues in a limited context appropriate to the scope of this paper.Keywords: Telerehabilitation; Telehealth; Telemedicine; Telepractice 

Impact of medical loss regulation on the financial performance of health insurers

The Affordable Care Act's regulation of medical loss ratios requires health insurers to use at least 80-85 percent of the premiums they collect for direct medical expenses (care delivery) or for efforts to improve the quality of care. To gauge this rule's effect on insurers' financial performance, we measured changes between 2010 and 2011 in key financial ratios reflecting insurers' operating profits, administrative costs, and medical claims. We found that the largest changes occurred in the individual market, where for-profit insurers reduced their median administrative cost ratio and operating margin by more than two percentage points each, resulting in a seven-percentage-point increase in their median medical loss ratio. Financial ratios changed much less for insurers in the small- and large-group markets.

Outcomes of Clinicians, Caregivers, Family Members and Adults with Spina Bifida Regarding Receptivity to use of the iMHere mHealth Solution to Promote Wellness

The purpose of this study was to gather information regarding the receptivity of clinicians, caregivers and family members, and adults with spina bifida (SB) to the use of a mHealth application, iMobile Health and Rehabilitation (iMHere) system. Surveys were administered to end user groups in conjunction with a conference presentation at the Spina Bifida Association's 38th Annual Conference. The survey results were obtained from a total of 107 respondents. Likert scale and qualitative results are provided in consideration of future application of the iMHere system in clinical practice. The results of this survey indicate respondents were receptive and supportive with regard to adopting such a system for personal and professional use. Challenges likely to be encountered in the introduction of the iMHere system are also revealed and discussed.

Evaluation of a telerehabilitation system for community-based rehabilitation

The use of web-based portals, while increasing in popularity in the fields of medicine and research, are rarely reported on in community-based rehabilitation programs. A program within the Pennsylvania Office of Vocational Rehabilitation's Hiram G. Andrews Center, the Cognitive Skills Enhancement Program (CSEP), sought to enhance organization of program and participant information and communication between part- and full-time employees, supervisors and consultants. A telerehabilitation system was developed consisting of (1) a web-based portal to support a variety of clinical activities, and (2) the Versatile Integrated System for Telerehabilitation (VISYTER) video-conferencing system to support the collaboration and delivery of rehabilitation services remotely. This descriptive evaluation examines the usability of the telerehabilitation system incorporating both the portal and VISYTER. Telerehabilitation system users include CSEP staff members from three geographical locations and employed by two institutions. The IBM After-Scenario Questionnaire (ASQ) and Post-Study System Usability Questionnaire (PSSUQ), the Telehealth Usability Questionnaire (TUQ), and two demographic surveys were administered to gather both objective and subjective information. Results showed generally high levels of usability. Users commented that the telerehabilitation system improved communication, increased access to information, improved speed of completing tasks, and had an appealing interface. Areas where users would like to see improvements, including ease of accessing/editing documents and searching for information, are discussed.

Factors contributing to impaired self-awareness of cognitive functioning in an HIV positive and at-risk population

PURPOSE

To examine the association between self-awareness of cognitive impairment and age, selected mood disorders, and type and severity of cognitive impairment in a sample of individuals with HIV/AIDS and at risk for HIV.

METHOD

75 subjects, 52 HIV+ and 23 at risk for HIV completed a psychosocial interview, the Patient's Assessment of Own Functioning (PAOF) questionnaire, and a battery of neuropsychological tests. Based upon the differences between their clinical impairment and self-reported impairment, subjects were classified as being "Underestimators", "Good Awareness", or "Impaired Awareness" with regard to self-awareness.

RESULTS

Those with more severe cognitive impairment were less aware than those with normal or borderline cognitive impairment. A one-way ANOVA suggested that the Impaired Awareness group differed significantly from the Underestimators on the Rey Figure Immediate and Delayed Recall tasks, and from both the Underestimators and Good Awarenesss groups on the Digit Symbol Substitution Task. There were significant differences among all awareness groups on the test of Simple Reaction Time. Furthermore there is some suggestion that age may contribute to impaired self-awareness. The role of HIV in self-awareness remains unclear, as both, individuals with HIV and at risk, demonstrated impaired self-awareness.

CONCLUSIONS

Overall, impaired awareness was associated with poorer test performance, suggesting a relationship between awareness and sustained complex attention and visual spatial processing. This research has implications for understanding factors contributing to poor awareness among individuals with cognitive impairment.

Enhancing quality of life through telerehabilitation

Telerehabilitation is an emerging method of delivering rehabilitation services that uses technology to serve clients, clinicians, and systems by minimizing the barriers of distance, time, and cost. The driving force for telerehabilitation has been as an alternative to face-to-face rehabilitation approaches to reduce costs, increase geographic accessibility, or act as a mechanism to extend limited resources. A rationale for telerehabilitation is the potential to enhance outcomes beyond what may result from face-to-face interventions by enabling naturalistic, in vivo interventions. There is considerable support for the value of interventions delivered in the natural environment, ranging from addressing efficacy concerns by addressing problems of generalization, to increasing patient participation, including environmental context in rehabilitation, and increasing patient satisfaction. Further clinical and research exploration should explore telerehabilitation as a tool for the delivery of rehabilitation services in vivo.

Telerehabilitation clinical and vocational applications for assistive technology: research, opportunities, and challenges

Rehabilitation service providers in rural or underserved areas are often challenged in meeting the needs of their complex patients due to limited resources in their geographical area. Recruitment and retention of the rural clinical workforce are beset by the ongoing problems associated with limited continuing education opportunities, professional isolation, and the challenges inherent in coordinating rural community healthcare. People with disabilities who live in rural communities also face challenges accessing healthcare. Traveling long distances to a specialty clinic for necessary expertise may be troublesome due to inadequate or unavailable transportation, disability specific limitations, and financial limitations. Distance and lack of access are just two threats to quality of care that now being addressed by the use of videoconferencing, information exchange, and other telecommunication technologies that facilitate telerehabilitation. This white paper illustrates and summarizes clinical and vocational applications of telerehabilitation. We provide definitions related to the fields of telemedicine, telehealth, and telerehabilitation, and consider the impetus for telerehabilitation. We review the telerehabilitation literature for assistive technology applications; pressure ulcer prevention; virtual reality applications; speech-language pathology applications; seating and wheeled mobility applications; vocational rehabilitation applications; and cost-effectiveness. We then discuss external telerehabilitation influencers, such as the positions of professional organizations. Finally, we summarize clinical and policy issues in a limited context appropriate to the scope of this paper.

The impact of HMO penetration on the relationship between nurse staffing and quality

While there are a number of studies examining the relationship between nurse staffing and quality, none has examined structural differences in the relationship between nurse staffing and quality contingent upon the level of managed care penetration. We used administrative data, and a dynamic panel data model to examine this relationship in a panel of 422 acute care hospitals from 1990 to 1995. We found that there were significant differences in the relationship between nurse staffing and both mortality and length of stay depending upon the level of HMO penetration in the hospital's market.

A longitudinal examination of hospital registered nurse staffing and quality of care

OBJECTIVE

To evaluate previous research findings of the relationship between nurse staffing and quality of care by examining the effects of change in registered nurse staffing on change in quality of care.

DATA SOURCES/STUDY SETTING

Secondary data from the American Hospital Association (AHA)(nurse staffing, hospital characteristics), InterStudy and Area Resource Files (ARF) (market characteristics), Centers for Medicare and Medicaid Services (CMS) (financial performance), and Healthcare Cost and Utilization Project (HCUP) (quality measures-in-hospital mortality ratio and the complication ratios for decubitus ulcers, pneumonia, and urinary tract infection, which were risk-adjusted using the Medstat disease staging algorithm).

STUDY DESIGN

Data from a longitudinal cohort of 422 hospitals were analyzed from 1990-1995 to examine the relationships between nurse staffing and quality of care.

DATA COLLECTION/EXTRACTION METHODS

A generalized method of moments estimator for dynamic panel data was used to analyze the data. Principal Findings. Increasing registered nurse staffing had a diminishing marginal effect on reducing mortality ratio, but had no consistent effect on any of the complications. Selected hospital characteristics, market characteristics, and financial performance had other independent effects on quality measures.

CONCLUSIONS

The findings provide limited support for the prevailing notion that improving registered nurse (RN) staffing unconditionally improves quality of care.

Benefits of oral supplementation with and without synbiotics in young children with acute bacterial infections

Acutely ill children (n = 129) aged 1-6 years receiving antibiotic therapy were randomized to receive a nutritional supplement with (PS) or without (P) synbiotics or a fruit-flavored drink (D) with their medications. Group PS had significantly greater weight gains (versus D) following antibiotic therapy. The percentages of subjects without bacterial illnesses 14 days following antibiotic therapy were as follows: 94.3% (PS), 87.8% (D), and 80.6% (P). PS (vs D) significantly increased fecal Lactobacillus in a subset of subjects. Oral supplements increase energy intake and promote weight gain in acutely ill children receiving antibiotics; synbiotics may confer additional benefits by increasing bifidobacteria levels.

MR staging of primary colorectal carcinoma: comparison with surgical and histopathologic findings

BACKGROUND

We retrospectively evaluated the accuracy of magnetic resonance (MR) imaging in staging colorectal cancer and assessing local tumor extent, nodal involvement, and distant abdominal and pelvic metastases.

METHODS

Forty-eight patients with primary colorectal carcinoma were referred for presurgical abdominal and pelvic MR imaging. MR imaging included T1-weighted, fat-suppressed T2-weighted, and fat-suppressed gadolinium-enhanced spin gradient-echo imaging. The prospective interpretations of the MR examinations were reviewed. MR depiction of local tumor extent, nodal involvement, and distant metastases at 18 anatomic locations was noted and compared with subsequent surgical and histopathologic findings.

RESULTS

Overall TNM MR staging agreed with surgical and pathologic staging in 41 (85%) of 48 patients, including 21 (78%) of 27 colon cancers and 20 (95%) of 21 rectal cancers. For depth of tumor penetration, which was evaluable in 44 patients, MR imaging agreed with pathologic results in 38 (86%) of 44 patients, including 22 (88%) of 25 colon cancers and 16 (84%) of 19 rectal cancers. In 42 (95%) of 44 patients, MR images correctly distinguished tumor confined to the bowel wall (T0, T1, and T2) from tumor with transmural tumor extension (T3 and T4). Regional nodal metastases were depicted in 15 of 22 patients (sensitivity, 68%; accuracy, 83%). Nodal metastases were better depicted for rectal cancer in eight of nine patients, compared with colon cancer in seven of 13 patients. Distant metastases were correctly depicted on MR imaging in 13 of 14 patients (sensitivity, 93%; accuracy, 98%). In the site-by-site analysis, MR imaging prospectively depicted 66 of 77 sites of surgically confirmed metastatic tumor in the abdomen and pelvis (sensitivity, 86%; specificity, 99%; accuracy, 98%).

CONCLUSION

MR imaging using currently available techniques can effectively image local tumor extent and distant metastases in patients with colorectal carcinoma. Especially for colon cancer, incomplete depiction of nodal metastases in normal-size lymph nodes remains a limitation of cross-sectional imaging studies.

Nurse staffing, quality, and financial performance

In examining the relationship among nurse staffing, quality of care, and financial performance, prior empirical studies used competing measures and applied different levels of analysis. Using longitudinal data from 1990 through 1995, our study applied a dynamic econometric model to evaluate whether hospitals that changed their nurse staffing and quality of care affected their financial performance. Sampling 422 hospitals over this study period, we found a statistically significant increase in operating costs when registered nurse levels increase, but no statistically significant decrease in profit. Higher levels of non-nurse staffing caused higher operating expenses, as well as lower profits.

A comprehensive strategy for the evaluation and triage of the chest pain patient: a cost comparison study

BACKGROUND

Our objective was to determine the cost-effectiveness of a comprehensive, risk-based triage system, composed of multiple critical pathways, with the use of early myocardial perfusion imaging (MPI) in low-risk patients. We found previously that a chest pain evaluation system that uses MPI in low-risk patients was safe and effective, but the cost-effectiveness of this approach was not studied.

METHODS AND RESULTS

We compared two groups. The Acute Cardiac Team (ACT) group (n = 874) was assigned prospectively to 1 of 4 risk levels by emergency department (ED) physicians. Level 1, 2, and 3 patients were admitted; level 4 patients were evaluated in the ED. Level 3 and 4 patients underwent ED MPI. The control group (n = 713) represented consecutive patients evaluated in the prior year according to standard care and assigned retrospectively to an ACT level based on the presenting electrocardiographic and clinical data. Record and hospital administrative data were assessed for clinical variables, outcomes, lengths of stay, and all expenses incurred within 30 days of the index visit. The baseline characteristics of the two groups were similar, including age, sex, myocardial infarction prevalence, and 30-day revascularization rates within each level or between the two groups. Mean costs per encounter were reduced for the ACT patients for each level, which was significant when all patients were compared ($5,030 +/- $7,081 vs $6,044 +/- $10,432, P =.02). Use of MPI in the low-risk patients was associated with reduced costs (level 3, $4,958 +/- $4,948 vs $5,051 +/- $7,036; level 4, $1,529 +/- $2,664 vs $1,794 +/- $6,854) and was associated with a significantly lower angiography rate and shorter length of stay.

CONCLUSIONS

Implementation of a comprehensive strategy for chest pain evaluation and triage reduced overall costs for patients with chest pain on presentation. Acute MPI in the ED setting did not increase net cost.

Changes in electroencephalogram and autonomic cardiovascular activity during induction of anesthesia with sevoflurane compared with halothane in children

BACKGROUND

This study was design to assess clinical agitation, electroencephalogram (EEG) and autonomic cardiovascular activity changes in children during induction of anesthesia with sevoflurane compared with halothane using noninvasive recording of EEG, heart rate, and finger blood pressure.

METHODS

Children aged 2-12 yr premedicated with midazolam were randomly assigned to one of three induction techniques: 7% sevoflurane in 100% O2 (group SevoRAPID); 2%, 4%, 6%, and 7% sevoflurane in 100% O2 (group SevoINCR); or 1%, 2%, 3%, and 3.5% halothane in 50% N2O-50% O2 (group HaloN2O). An additional group of children who received 7% sevoflurane in 50% N2O-50% O2 (group SevoN2O) was enrolled after completion of the study. Induction was videotaped. EEG, heart rate, and finger blood pressure were continuously recorded during induction until 5 min after tracheal intubation and analyzed in frequency domain using spectral analysis.

RESULTS

Agitation was more frequent when anesthesia was induced with 100% O2 compared to the mixture of oxygen and nitrous oxide. No seizures were recorded in any group. In the four groups, induction of anesthesia was associated with an increase in EEG total spectral power and a shift toward the low-frequency bands. Sharp slow waves were present on EEG tracings of the three sevoflurane groups, whereas slow waves and fast rhythms (spindles) were observed in the halothane group. Sevoflurane induced a greater withdrawal of parasympathetic activity than halothane and a transient relative increase in sympathetic vascular tone at loss of eyelash reflex.

CONCLUSIONS

Agitation observed during sevoflurane induction was not associated with seizures. Sevoflurane induction induced a marked inhibition of parasympathetic control of heart rate.

Investigation of intraoperative brain deformation using a 1.5-T interventional MR system: preliminary results

All image-guided neurosurgical systems that we are aware of assume that the head and its contents behave as a rigid body. It is important to measure intraoperative brain deformation (brain shift) to provide some indication of the application accuracy of image-guided surgical systems, and also to provide data to develop and validate nonrigid registration algorithms to correct for such deformation. We are collecting data from patients undergoing neurosurgery in a high-field (1.5 T) interventional magnetic resonance (MR) scanner. High-contrast and high-resolution gradient-echo MR image volumes are collected immediately prior to surgery, during surgery, and at the end of surgery, with the patient intubated and lying on the operating table in the operative position. In this paper we report initial results from six patients: one freehand biopsy, one stereotactic functional procedure, and four resections. We investigate intraoperative brain deformation by examining threshold boundary overlays and difference images and by measuring ventricular volume. We also present preliminary results obtained using a nonrigid registration algorithm to quantify deformation. We found that some cases had much greater deformation than others, and also that, regardless of the procedure, there was very little deformation of the midline, the tentorium, the hemisphere contralateral to the procedure, and ipsilateral structures except those that are within 1 cm of the lesion or are gravitationally above the surgical site.

Using peer helpers for tuberculosis prevention

The authors report on a novel and effective peer helper program initiated by the University of Iowa Student Health Service (SHS) in fall 1992 to help prevent the development of active tuberculosis among foreign nationals attending the university. Before instituting the peer program, compliance with tuberculosis-prevention efforts for those students eligible for treatment was less than 5%. Since the peer program was initiated, compliance has risen to 50%.

Stability and change in functional assessment of patients with geropsychiatric disorders

OBJECTIVES

Functional assessments of patients with geropsychiatric disorders accomplished by self-rating, informant rating, and performance test were compared.

METHOD

Fifty-eight inpatients with major depression or progressive dementia were evaluated on three occasions over 6 months with informant and patient versions of the Activities of Daily Living Scale of the Older Americans Resources and Services Multidimensional Functional Assessment (OARS-ADL) and with the Performance Assessment of Self-Care Skills (PASS).

RESULTS

Patients' scores became significantly worse (p < .01) on the informant version of the OARS-ADL and the PASS. Self-ratings with the OARS-ADL did not worsen significantly (p > .05).

CONCLUSION

Agreement between informant rating and performance test concerning functional status of patients with dementia was good. Elderly patients with depression may experience subtle deterioration that only becomes apparent on performance tests.
