Using the Standing and Walking Assessment Tool at Discharge Predicts Community Outdoor Walking Capacity in Persons With Traumatic Spinal Cord Injury.

OBJECTIVE: The Standing and Walking Assessment Tool (SWAT) standardizes the timing and content of walking assessments during inpatient rehabilitation by combining 12 stages ranging from lowest to highest function (0, 0.5, 1A, 1B, 1C, 2A, 2B, 2C, 3A, 3B, 3C, and 4) with 5 standard measures: the Berg Balance Scale, the modified Timed "Up & Go" test, the Activities-specific Balance Confidence Scale, the modified 6-Minute Walk Test, and the 10-Meter Walk Test (10MWT). This study aimed to determine if the SWAT at rehabilitation discharge could predict outdoor walking capacity 1-year after discharge in people with traumatic spinal cord injury. METHODS: This retrospective study used data obtained from the Rick Hansen Spinal Cord Injury Registry from 2014 to 2020. Community outdoor walking capacity was measured using the Spinal Cord Independence Measure III (SCIM III) outdoor mobility score obtained 12 (±4) months after discharge. Of 206 study participants, 90 were community nonwalkers (ie, SCIM III score 0-3), 41 were community walkers with aids (ie, SCIM III score 4-6), and 75 were independent community walkers (ie, SCIM III score 7-8). Bivariate, multivariable regression, and an area under the receiver operating characteristic curve analyses were performed. RESULTS: At rehabilitation discharge, 3 significant SWAT associations were confirmed: 0-3A with community nonwalkers, 3B/higher with community walkers with and without an aid, and 4 with independent community walkers. Moreover, at discharge, a higher (Berg Balance Scale, Activities-specific Balance Confidence Scale), faster (modified Timed "Up & Go," 10MWT), or further (10MWT) SWAT measure was significantly associated with independent community walking. Multivariable analysis indicated that all SWAT measures, except the 10MWT were significant predictors of independent community walking. Furthermore, the Activities-Specific Balance Confidence Scale had the highest area under the receiver operating characteristic score (0.91), demonstrating an excellent ability to distinguish community walkers with aids from independent community walkers. CONCLUSION: The SWAT stage and measures at discharge can predict community outdoor walking capacity in persons with traumatic spinal cord injury. Notably, a patient's confidence in performing activities plays an important part in achieving walking ability in the community. IMPACT: The discharge SWAT is useful to optimize discharge planning.

Interrater reliability of the Standing and Walking Assessment Tool for spinal cord injury.

STUDY DESIGN: Psychometric study. OBJECTIVES: The Standing and Walking Assessment Tool (SWAT) is a standardized approach to the evaluation of standing and walking capacity following traumatic spinal cord injury (tSCI) in Canada. The SWAT classifies individuals with a tSCI into 12 stages of standing and walking capacity that are paired with well-established outcome measures, such as the Berg Balance Scale and 10-m Walk Test. Prior research has demonstrated the validity and responsiveness of the SWAT stages; however, the reliability remains unknown. The objective of this study was to evaluate the interrater reliability of the SWAT stages. SETTING: Inpatient units of two Canadian rehabilitation hospitals. METHODS: Adults with sub-acute tSCI were recruited. SWAT stage was evaluated for each participant by two physical therapists separately. The two therapists aimed to complete the evaluations within one day of each other. To evaluate interrater reliability, the percentage agreement between the SWAT stages rated by the two physical therapists was calculated, along with a linear weighted kappa statistic with a 95% CI. RESULTS: Forty-five individuals with sub-acute tSCI (36 males, 9 females, mean (SD) age of 54.8 (17.9) years) participated. The percentage agreement in SWAT stages between the two physical therapists was 75.6%. A kappa statistic of 0.93 with a 95% CI, 0.81-1.05 was obtained. In cases where therapists disagreed (18% of participants), therapists differed by 1-2 stages only. CONCLUSIONS: The SWAT stages have high interrater reliability, providing further support for the use of the SWAT in rehabilitation practice in Canada.

Validity and responsiveness of the Standing and Walking Assessment Tool for sub-acute traumatic spinal cord injury.

STUDY DESIGN: This is a retrospective longitudinal study. OBJECTIVE: The Standing and Walking Assessment Tool (SWAT) combines stages of standing and walking recovery (SWAT stages) with established measures (Berg Balance Scale (BBS), 10-m walk test (10MWT), 6-min walk test (6MWT), and modified Timed Up-and-Go (mTUG)). We evaluated the SWAT's validity (known-groups and convergent) and responsiveness among inpatients with sub-acute, traumatic spinal cord injury (SCI). SETTING: Ten Canadian rehabilitation hospitals. METHODS: Upon admission, SWAT stage and core measures (BBS, 10MWT, 6MWT, and mTUG), International Standards for Neurological Classification of SCI sensory and motor scores, and Spinal Cord Independence Measure III (SCIM) were collected from 618 adults with SCI. Known-groups validity was evaluated by comparing SWAT stage distributions across American Spinal Injury Association Impairment Scale (AIS) classification. Convergent validity was evaluated by correlating SWAT stages with scores on other measures using Spearman's rho. The SWAT (stage and core measures) was re-administered at discharge. To evaluate responsiveness, SWAT stages at admission and discharge were compared. The standardized response mean (SRM) was used to evaluate the responsiveness of core SWAT measures. RESULTS: The SWAT stage distribution of participants with AIS D injuries differed from those of participants with AIS A-C injuries (p ≤ 0.002). SWAT stages correlated strongly with BBS and motor scores (ρ = 0.778-0.836), and moderately with SCIM, mTUG, 10MWT, 6MWT, and sensory scores (ρ = 0.409-0.692). Discharge SWAT stage was greater than the admission stage (p < 0.0001). The BBS was the most responsive core SWAT measure (SRM = 1.26). CONCLUSIONS: The SWAT is a valid and responsive approach to the measurement of standing and walking ability during sub-acute SCI.

The standing and walking assessment tool for individuals with spinal cord injury: A qualitative study of validity and clinical use.

Context/Objective: The Spinal Cord Injury (SCI) Standing and Walking Assessment Tool (SWAT) combines stages of walking recovery with measures of balance and walking. It standardizes the timing and content of walking assessment in inpatient rehabilitation. The study aims were: (1) Evaluate the content validity of the SWAT stages of walking recovery, and (2) Understand physical therapists' (PTs) experiences using the SWAT to gauge acceptance, implementation and impact. Design: Qualitative, exploratory study. Setting: Nine Canadian rehabilitation hospitals. Participants: Thirty-four PTs who had used the SWAT ≥10 times. Interventions: Seven focus group meetings were completed. Semi-structured questions queried the content, order and spacing of SWAT stages, and current SWAT use (i.e. processes, challenges, facilitators, impact on practice). Meetings were audio-recorded and transcribed. Themes and categories were derived through a conventional content analysis. Outcome Measure: Not applicable. Results: PTs agreed with the ordering and content of the SWAT stages, but reported unequal spacing between stages. Three themes related to PTs' use of the SWAT were identified: (1) Variable process: SWAT implementation varied across sites, PTs and patients. (2) Implementation challenges: unfamiliarity of the SWAT, lack of time, not required by place of work, and patients who are outliers or have poor gait quality. (3) Potential to influence clinical decision-making: the SWAT did not influence clinical decisions, but PTs recognized the potential of the tool to do so. Conclusions: Content validity of the SWAT stages was supported and implementation challenges identified. Variability in SWAT implementation may reflect the heterogeneity and person-centeredness of SCI rehabilitation.

Evolutions in clinical reasoning assessment: The Evolving Script Concordance Test.

INTRODUCTION: Script concordance testing (SCT) is a method of assessment of clinical reasoning. We developed a new type of SCT case design, the evolving SCT (E-SCT), whereby the patient's clinical story is "evolving" and with thoughtful integration of new information at each stage, decisions related to clinical decision-making become increasingly clear. OBJECTIVES: We aimed to: (1) determine whether an E-SCT could differentiate clinical reasoning ability among junior residents (JR), senior residents (SR), and pediatricians, (2) evaluate the reliability of an E-SCT, and (3) obtain qualitative feedback from participants to help inform the potential acceptability of the E-SCT. METHODS: A 12-case E-SCT, embedded within a 24-case pediatric SCT (PaedSCT), was administered to 91 pediatric residents (JR: n = 50; SR: n = 41). A total of 21 pediatricians served on the panel of experts (POE). A one-way analysis of variance (ANOVA) was conducted across the levels of experience. Participants' feedback on the E-SCT was obtained with a post-test survey and analyzed using two methods: percentage preference and thematic analysis. RESULTS: Statistical differences existed across levels of training: F = 19.31 (df = 2); p < 0.001. The POE scored higher than SR (mean difference = 10.34; p < 0.001) and JR (mean difference = 16.00; p < 0.001). SR scored higher than JR (mean difference = 5.66; p < 0.001). Reliability (Cronbach's α) was 0.83. Participants found the E-SCT engaging, easy to follow and true to the daily clinical decision-making process. CONCLUSIONS: The E-SCT demonstrated very good reliability and was effective in distinguishing clinical reasoning ability across three levels of experience. Participants found the E-SCT engaging and representative of real-life clinical reasoning and decision-making processes. We suggest that further refinement and utilization of the evolving style case will enhance SCT as a robust, engaging, and relevant method for the assessment of clinical reasoning.

Transforming Medical Assessment: Integrating Uncertainty Into the Evaluation of Clinical Reasoning in Medical Education.

In an age where practicing physicians have access to an overwhelming volume of clinical information and are faced with increasingly complex medical decisions, the ability to execute sound clinical reasoning is essential to optimal patient care. The authors propose two concepts that are philosophically paramount to the future assessment of clinical reasoning in medicine: assessment in the context of "uncertainty" (when, despite all of the information that is available, there is still significant doubt as to the best diagnosis, investigation, or treatment), and acknowledging that it is entirely possible (and reasonable) to have more than "one correct answer." The purpose of this article is to highlight key elements related to these two core concepts and discuss genuine barriers that currently exist on the pathway to creating such assessments. These include acknowledging situations of uncertainty, creating clear frameworks that define progressive levels of clinical reasoning skills, providing validity evidence to increase the defensibility of such assessments, considering the comparative feasibility with other forms of assessment, and developing strategies to evaluate the impact of these assessment methods on future learning and practice. The authors recommend that concerted efforts be directed toward these key areas to help advance the field of clinical reasoning assessment, improve the clinical care decisions made by current and future physicians, and have positive outcomes for patients. It is anticipated that these and subsequent efforts will aid in reaching the goal of making future assessment in medical education more representative of current-day clinical reasoning and decision making.

Reconsidering "inattention" in attention-deficit hyperactivity disorder: implications for neuropsychological assessment and intervention.

Attention-deficit hyperactivity disorder (ADHD) does not exist. This explicit statement needs elucidation of course given ADHD is a common neurodevelopmental disorder, but it provides the reader with the impetus to reconsider long-held beliefs about this condition and its treatment. Surely, there is a disorder called ADHD from which this thesis is framed, but primary attention and hyperactivity-impulsivity problems are mediated by different albeit interrelated brain systems. Like many neurodevelopmental disorders (e.g., learning disabilities, autism spectrum disorder), the medical and psychological professions have used a single, large inclusive ADHD diagnostic category to represent children with different etiologies for their overt symptoms. Despite neurobiological differences among children diagnosed with ADHD, the clinical position that attention-deficit or primary attention problems are sufficient for ADHD identification undermines clinical practice. This commonly accepted dubious position not only undermines the diagnostic utility of our neuropsychological measures, but it attenuates treatment effects as well. Supported with evidence from our ongoing ADHD research program, this data-based review will support these contentions and provide implications for diagnosis and treatment of children with attention problems.

What is the financial state of medical students from rural backgrounds during tuition fee deregulation?

INTRODUCTION: We sought to examine the financial state of medical students from rural backgrounds during a time of tuition fee deregulation. METHODS: We surveyed incoming classes from 2007 to 2011 at the University of Calgary. Community background, expected educational debt at graduation, educational debt at entry to medical school and parental income were collected for analysis. Data were analyzed using the Χ² test, analysis of variance and the Newman-Keuls multiple comparison test. RESULTS: The overall response rate was 95.3%. Of the 571 (93.5%) respondents who supplied data on their background and debt, 94.4% expected to have educational debt at graduation. The mean projected educational debt at graduation by medical students from both rural ($107 226 [95% confidence interval (CI) $98 030-$116 423]) and regional ($99 456 [95% CI $91 905-$107 006]) backgrounds was significantly greater than the debt projected by students from metropolitan ($88 565 [95% CI $83 607-$93 524]) backgrounds. Medical students who came from rural backgrounds had the highest mean debt at entry to medical school ($33 053 [95% CI $25 715-$40 391]) compared with their peers from regional ($23 253 [95% CI $16 621-$29 885]) and metropolitan ($22 053 [95% CI $17 344-$26 762]) backgrounds. Students of rural origin also had parents whose mean income ($104 024 [95% CI $75 976-$132 173]) was significantly lower than the mean parental income of their peers who originated from regional ($143 167 [95% CI $119 898-$166 435]) and metropolitan ($150 339 [95% CI $135 241-165 438]) centres. CONCLUSION: Rising tuition and subsequent debt may be affecting the diversity of medical students' backgrounds. Financial programs dedicated to rural-background students and their interest in medicine may become necessary.

Assessment of non-cognitive traits through the admissions multiple mini-interview.

CONTEXT: Contemporary studies have shown that traditional medical school admissions interviews have strong face validity but provide evidence for only low reliability and validity. As a result, they do not provide a standardised, defensible and fair process for all applicants. METHODS: In 2006, applicants to the University of Calgary Medical School were interviewed using the multiple mini-interview (MMI). This interview process consisted of 9, 8-minute stations where applicants were presented with scenarios they were then asked to discuss. This was followed by a single 8-minute station that allowed the applicant to discuss why he or she should be admitted to our medical school. Sociodemographic and station assessment data provided for each applicant were analysed to determine whether the MMI was a valid and reliable assessment of the non-cognitive attributes, distinguished between the non-cognitive attributes, and discriminated between those accepted and those placed on the waitlist (waiting list). We also assessed whether applicant sociodemographic characteristics were associated with acceptance or waitlist status. RESULTS: Cronbach's alpha for each station ranged from 0.97-0.98. Low correlations between stations and the factor analysis suggest each station assessed different attributes. There were significant differences in scores between those accepted and those on the waitlist. Sociodemographic differences were not associated with status on acceptance or waiting lists. DISCUSSION: The MMI is able to assess different non-cognitive attributes and our study provides additional evidence for its reliability and validity. The MMI offers a fairer and more defensible assessment of applicants to medical school than the traditional interview.
