KTDRR Represents at
What Works Global Summit

Drs. Carlton Fong and Cindy Cai will present a paper, Translating Research to Practice from Campbell Systematic Reviews on Interventions for Individuals with Disabilities: Case Examples of Knowledge Translation, at the upcoming What Works Global Summit, taking place in London, Sept. 26–28, 2016. Below is a description of the presentation:

This presentation will highlight findings from recent systematic reviews in the field of disability research with a focus on knowledge translation. Evidence from published Campbell Collaboration systematic reviews from the Disability Subgroup will be discussed, followed by case studies on how the research can be mapped onto areas of practice and policy. Presenters will walk through case examples of knowledge translation using a variety of strategies. For example, rubrics that evaluate the relevance of the systematic reviews for policy and practice will emphasize the prominence (or lack thereof) in synthetic evidence in disability research. Topics will range from psychological interventions and vocational rehabilitation that span a variety of populations such as cancer survivors and individuals with autism spectrum disorders or physical disabilities.

KTER Center Webinar: Offering Tailored Technical Assistance
as a Knowledge Translation Strategy

Tuesday August 30 from 2:00-3:00 p.m. Central.

Ryan Williams, PhD., Research Director for the Center on Knowledge Translation for Employment Research, will present findings from a study testing a knowledge translation strategy among a business-oriented audience.

Study participants had supervisory authority, worked in human resources, or were professionals, such as vocational rehabilitation counselors, whose responsibilities could involve supporting employees with cancer in the workplace.

The study tested whether an offer of follow-up technical assistance helped to sustain knowledge gains and promote application among individuals who attended a webcast and received other informational resources about cancer survivors' employment issues and the reasonable accommodations process. The presentation will also describe business outreach planned in the KTER Center's new award cycle, which will focus on collaboration with the National Employment Team (NET) of the Council of State Administrators of Vocational Rehabilitation (CSAVR).

We have applied for 1 hour of CRC Credit for this webcast.

Bakas, T., Clark, P. C., Kelly-Hayes, M., King, R. B., Lutz, B. J., Miller, E. L., & American Heart Association Council on Cardiovascular and Stroke Nursing and the Stroke Council. (2014). Evidence for stroke family caregiver and dyad interventions: a statement for healthcare professionals from the American Heart Association and American Stroke Association. Stroke; a Journal of Cerebral Circulation, 45(9), 2836-2852. doi:10.1161/STR.0000000000000033
Performs a critical analysis of 17 caregiver intervention studies and 15 caregiver/stroke survivor dyad intervention studies to provide evidence-based recommendations for the design and implementation of future studies of stroke family caregiver and dyad interventions.
PMID: 25034718

Davies, L. E., & Oliver, C. (2014). The purported association between depression, aggression, and self-injury in people with intellectual disability: a critical review of the literature. American Journal on Intellectual and Developmental Disabilities, 119(5), 452-471. doi:10.1352/1944-7558-119.5.452
The aim of this review is to evaluate research reporting on the correlation between challenging behavior, specifically aggression and self-injury, and depression, in people with an intellectual disability. The authors see this as a first step toward evaluating whether challenging behaviors might be considered as depressive equivalent symptoms. They find that the associations between depression and aggression, and depression and self-injury, are equivocal and that the results of existing studies are open to validity threats. Thus, more sophisticated research of the association is warranted.

Gurgel, L. G., Vidor, D. C., Joly, M. C., & Reppold, C. T. (2014). Risk factors for proper oral language development in children: a systematic literature review. Codas, 26(5), 350-356. doi:S2317-17822014000500350
Finds that in the literature on risk factors for language development in 0-12 years olds the major ones listed are: family dynamics, interaction with parents, immediate social environment, and encouragement given in the first years of life. The authors also suggest that brain injury, persistent otitis media, and cardiac surgery may be related to language disorders, besides food type and parental counseling.

Pain Medicine (Malden, Mass.), 15(9), 1619-1636. doi:10.1111/pme.12505
Identifies 14 RCTs for a systematic review, of which 9 are included in the meta-analysis. The authors find moderate-strong evidence for intermediate-term effectiveness of patient education on headache frequency, headache disability and quality of life. There is no evidence, however, for short- or intermediate-term effects of patient education on self-efficacy or depressive symptomatology.

BMC Health Services Research, 14, 397-6963-14-397. doi:10.1186/1472-6963-14-397
Based on the findings of 5 systematic reviews and 21 studies, 8 involving traumatic or acquired brain injury (ABI) and 18 concerning stroke, this systematic review concludes that use of integrated care improves functional outcome and reduces length of stay (LOS). The authors also conclude that there is evidence for improvements in process outcomes in acute and rehabilitation settings as a result of a quality monitoring intervention, and for the utility of early supported discharge teams for reducing morbidity and mortality and reducing LOS of stay for stroke survivors. They find little evidence for case management or the use of integrated care pathways for people with ABI.

Sets out to identify generic and epilepsy-specific patient-reported outcome (PRO) instruments used in childhood epilepsy research and to make explicit their conceptual approach and biopsychosocial content. Finds 3 generic and 13 epilepsy-specific PROs; 10 of 16 utilized a biopsychosocial health approach rather than a subjective quality of life (QoL) or health-related QoL (HRQoL) approach. In most measures, >25% of the items represented participation and activity components of the ICF-CY, while a high proportion of environment items was found in 1 only.

Claims that theory-based approaches to evaluation, such as realist evaluation (RE), may be better-suited to examination of complex knowledge translation (KT) interventions, to understand what works, for whom, and under what conditions. In order to assess the state-of-the-art in healthcare KT, the authors identified 14 studies on 6 study projects in a variety of settings and representing a range of interventions. While most studies mentioned context (C), mechanism (M) and outcome (O), few set forth the development of C-M-O configuration and a testable hypothesis based on it. Salter and Kothari conclude that use of RE in knowledge translation is relatively new; however, they expect that “as researchers approach challenges and explore innovations in its application, rich and detailed accounts may improve feasibility”.

The authors perform a systematic review to examine the effectiveness trials of train the trainer (TTT) behavioral interventions for individuals with autism spectrum disorders. Based on 12 studies (of which only 1 is judged to be of high quality) they find positive effects of the intervention across various participant outcomes, including cognition, language, and autism symptoms, which effects. However, varied by the subjects’ developmental level.

Archives of Gerontology and Geriatrics, 59(2), 195-203. doi:10.1016/j.archger.2014.06.006
Presents a systematic review (12 studies with 752 participants) to identify correlates of physical activity (PA), which shows promise as a modifiable lifestyle intervention for dementia. Positively associated with PA were energy intake, resting metabolic rate, fat free mass, gait speed, global motor function, overall and physical health related quality of life (HRQOL), higher levels of social functioning and reduced apathy. A secondary analysis (9 data sets reanalyzed) showed as correlates increased energy intake, resting metabolic rate, fat free mass, gait speed, global motor function, overall and physical HRQOL, higher levels of social functioning and reduced apathy, as well as taking 4 medications, dizziness, lower ADL function, a history of falls, less waking hours in the day, more autonomic problems and delirium were associated with PA.

The authors note that clinicians whose patients are at risk of fecal contamination of wounds have used various methods and devices, but judge that little work has been done to evaluate the various ad hoc devices used, or the more formal, purpose-designed systems. The goal of their paper is to consider the use of purpose-designed fecal or bowel-management systems.

Based on analysis of 43 published reviews of qualitative studies determines that for 30, 80% or more of the primary studies included could have been found by consulting CINAHL (Cumulative Index to Nursing and Allied Health Literature) only. On the other hand, across 43 reviews, from 5 to 33 primary studies were indexed in CINAHL only, and could not have been found in the other bibliographic databases the original authors consulted. Concludes that CINAHL is a good source of primary qualitative studies for an evidence synthesis.
