Reducing alcohol use among 9th grade students: 6 month outcomes of a brief,Web-based intervention

This study tested a brief, Web-based personalized feedback program aimed at reducing alcohol use and alcohol-related consequences among 9th grade students (N = 513). Results indicated no differences between the control group and intervention group on either frequency of drinking or alcohol-related consequences at the 6-month follow-up. Reductions in alcohol use and the associated consequences found at the 3-month follow-up were not sustained across the academic year. Results indicate that brief, Web-based feedback programs may not be sufficient to provide a sustained impact on alcohol use and alcohol-related consequences over time, suggesting either booster sessions or adjunctive interventions, such as parent-based interventions, may be warranted for this age group.

Effects of audit and feedback on professional practice in Geriatric Acute Care Units

PurposeTo evaluate the effects of audit and feedback on service delivery and patient functioning in Austrian Geriatric Acute Care Units.MethodsQuality initiative based on a standardised documentation form (core and optional data set) and a web-based performance feedback with peer comparison in 18 Geriatric Acute Care Units, representing 40% of all Austrian units. Main outcome measures were compliance with desired practice of geriatric care (comprehensive geriatric assessment [CGA], therapeutic consequences), discharge characteristics and mortality.ResultsOverall 22,279 patient records were documented between 2008 and 2010. Active involvement in the web-based feedback system was indicated by a high frequency of data queries per year, 1401, 3148 and 2883 for 2008, 2009 and 2010, respectively. The mean completion rate for CGA tests increased from 73% in 2008 to 78% in 2010 (P < 0.05). For centres with completion of core and optional data (n = 8), the average number of documented therapeutic interventions increased from 4.4 to 5.0 (P < 0.05). Those aspects of CGA focusing on activities of daily living, mobility and cognition prompted the greatest degree of corresponding therapeutic interventions (> 90%). A lower intervention rate was induced by the nutritional assessment (< 20%). Mortality and discharge characteristics such as level of care and percentage of patients living at home after discharge did not change over the time.ConclusionFollowing implementation of a web-based performance feedback with peer comparison in Austrian Geriatric Acute Care Units, an improvement in health care professionals’ compliance with desired practice of geriatric care, but not in patients’ discharge characteristics, was observed.

The relationship between vocal accuracy and variability to the level of compensation to altered auditory feedback

Auditory feedback plays an important role in monitoring vocal output and determining when adjustments are necessary. In this study a group of untrained singers participated in a frequency altered feedback experiment to examine if accuracy at matching a note could predict the degree of compensation to auditory feedback that was shifted in frequency. Participants were presented with a target note and instructed to match the note in pitch and duration. Following the onset of the participants’ vocalizations their vocal pitch was shifted down one semi-tone at a random time during their utterance. This altered auditory feedback was instantaneously presented back to them through headphones. Results indicated that note matching accuracy did not correlate with compensation magnitude, however, a significant correlation was found between baseline variability and compensation magnitude. These results suggest that individuals with a more stable baseline fundamental frequency rely more on feedforward control mechanisms than individuals with more variable vocal production. This increased weighting of feedforward control means they are less sensitive to mismatches between their intended vocal production and auditory feedback.     

Feasibility and effects of home-based smartphone-delivered automated feedback training for gait in people with Parkinson's disease: A pilot randomized controlled trial

BackgroundInertial measurement units combined with a smartphone application (CuPiD-system) were developed to provide people with Parkinson's disease (PD) real-time feedback on gait performance. This study investigated the CuPiD-system's feasibility and effectiveness compared with conventional gait training when applied in the home environment.MethodsForty persons with PD undertook gait training for 30 min, three times per week for six weeks. Participants were randomly assigned to i) CuPiD, in which a smartphone application offered positive and corrective feedback on gait, or ii) an active control, in which personalized gait advice was provided. Gait, balance, endurance and quality of life were assessed before and after training and at four weeks follow-up using standardized tests.ResultsBoth groups improved significantly on the primary outcomes (single and dual task gait speed) at post-test and follow-up. The CuPiD group improved significantly more on balance (MiniBESTest) at post-test (from 24.8 to 26.1, SD∼5) and maintained quality of life (SF-36 physical health) at follow-up whereas the control group deteriorated (from 50.4 to 48.3, SD∼16). No other statistically significant differences were found between the two groups. The CuPiD system was well-tolerated and participants found the tool user-friendly.ConclusionCuPiD was feasible, well-accepted and seemed to be an effective approach to promote gait training, as participants improved equally to controls. This benefit may be ascribed to the real-time feedback, stimulating corrective actions and promoting self-efficacy to achieve optimal performance. Further optimization of the system and adequately-powered studies are warranted to corroborate these findings and determine cost-effectiveness.     

Assessment of a Large-Scale Peer Learning Program’s Value by Manual Review of Case Submissions

ObjectivePrior studies used submission numbers or report addendum rates to measure peer learning programs’ (PLP) impact. We assessed the educational value of a PLP by manually reviewing cases submitted to identify factors correlating with meaningful learning opportunities (MLOs).MethodsThis institutional review board–exempted, retrospective study was performed in a large academic radiology department generating >800,000 reports annually. A PLP facilitating radiologist-to-radiologist feedback was implemented May 1, 2017, with subsequent pay-for-performance initiatives encouraging increasing submissions, >18,000 by 2019. Two radiologists blinded to submitter and receiver identity categorized 336 randomly selected submissions as a MLO, not meaningful, or equivocal, resolving disagreements in consensus review. Primary outcome was proportion of MLOs. Secondary outcomes included percent engagement by subspecialty clinical division and comparing MLO and report addendum rates via Fisher’s exact tests. We assessed association between peer learning category, pay-for-performance interventions, and subspecialty division with MLOs using logistic regression.ResultsOf 336 PLP submissions, 65.2% (219 of 336) were categorized as meaningful, 27.4% (92 of 336) not meaningful, and 7.4% (25 of 336) equivocal, with substantial reviewer agreement (86.0% [289 of 336], κ = 0.71, 95% confidence interval 0.64-0.78). MLO rate (65.2% [219 of 336]) was five times higher than addendum rate (12.9% [43 of 333]) for the cohort. MLO proportion (adjusted odds ratios 0.05-1.09) and percent engagement (0.5%-3.6%) varied between subspecialty divisions, some submitting significantly fewer MLOs (P < .01). MLO proportion did not vary between peer learning categories.ConclusionEducational value of a large-scale PLP, estimated through manual review of case submissions, is likely a more accurate measure of program impact. Incentives to enhance PLP use did not diminish the program’s educational value.     

Quantified self and human movement: A review on the clinical impact of wearable sensing and feedback for gait analysis and intervention

The proliferation of miniaturized electronics has fueled a shift toward wearable sensors and feedback devices for the mass population. Quantified self and other similar movements involving wearable systems have gained recent interest. However, it is unclear what the clinical impact of these enabling technologies is on human gait. The purpose of this review is to assess clinical applications of wearable sensing and feedback for human gait and to identify areas of future research. Four electronic databases were searched to find articles employing wearable sensing or feedback for movements of the foot, ankle, shank, thigh, hip, pelvis, and trunk during gait. We retrieved 76 articles that met the inclusion criteria and identified four common clinical applications: (1) identifying movement disorders, (2) assessing surgical outcomes, (3) improving walking stability, and (4) reducing joint loading. Characteristics of knee and trunk motion were the most frequent gait parameters for both wearable sensing and wearable feedback. Most articles performed testing on healthy subjects, and the most prevalent patient populations were osteoarthritis, vestibular loss, Parkinson's disease, and post-stroke hemiplegia. The most widely used wearable sensors were inertial measurement units (accelerometer and gyroscope packaged together) and goniometers. Haptic (touch) and auditory were the most common feedback sensations. This review highlights the current state of the literature and demonstrates substantial potential clinical benefits of wearable sensing and feedback. Future research should focus on wearable sensing and feedback in patient populations, in natural human environments outside the laboratory such as at home or work, and on continuous, long-term monitoring and intervention.
