Study design and setting: The databases PubMed, EBSCOhost CINAHL Complete, and IEEE Xplore were searched for relevant literature. The search strategy included published search filters for prediction model and impact studies, index terms and keywords for SCI, and relevant outcome measures able to assess functioning as reflected in the International Classification of Functioning, Disability and Health (ICF). The search was completed in October 2020. Results: We identified seven prediction model studies reporting twelve prediction models of functioning. The identified prediction models were mainly envisioned to be used for rehabilitation planning, however, also other possible applications were stated. The method predominantly used was regression analysis and the investigated predictors covered mainly the ICF components of body functions and activities and participation, next to characteristics of the health condition and health interventions. Conclusion: Findings suggest that the development of prediction models of functioning for use in clinical practice remains to be fully exploited. By providing a comprehensive overview of what has been done, this review informs future research on prediction models of functioning in SCI and contributes to an efficient use of research evidence.}, language = {en} } @article{HodelEhrmannScheelSaileretal.2021, author = {Hodel, Jsabel and Ehrmann, Cristina and Scheel-Sailer, Anke and Stucki, Gerold and Bickenbach, Jerome E. and Prodinger, Birgit}, title = {Identification of Classes of Functioning Trajectories and Their Predictors in Individuals With Spinal Cord Injury Attending Initial Rehabilitation in Switzerland}, series = {Archives of Rehabilitation Research and Clinical Translation}, volume = {3}, journal = {Archives of Rehabilitation Research and Clinical Translation}, number = {2}, pages = {100121}, year = {2021}, abstract = {Objectives: To identify classes of functioning trajectories in individuals with spinal cord injury (SCI) undergoing initial rehabilitation after injury and to examine potential predictors of class membership to inform clinical planning of the rehabilitation process. Design: Longitudinal analysis of the individual's rehabilitation stay using data from the Inception Cohort of the Swiss Spinal Cord Injury Cohort Study (SwiSCI). Setting: Initial rehabilitation in specialized centers in Switzerland. Participants: Individuals with newly acquired SCI (N=748; mean age, 54.66±18.38y) who completed initial rehabilitation between May 2013 and September 2019. The cohort was primarily composed of men (67.51\%), persons with paraplegia (56.15\%), incomplete injuries (67.51\%), and traumatic etiologies (55.48\%). Interventions: Not applicable. Main Outcome Measures: Functioning was operationalized with the interval-based sum score of the Spinal Cord Independence Measure version III (SCIM III). For each individual, the SCIM III sum score was assessed at up to 4 time points during rehabilitation stay. The corresponding time of assessment was recorded by the difference in days between the SCIM III assessment and admission to the rehabilitation program. Results: Latent process mixed model analysis revealed 4 classes of functioning trajectories within the present sample. Class-specific predicted mean functioning trajectories describe stable high functioning (n=307; 41.04\%), early functioning improvement (n=39; 5.21\%), moderate functioning improvement (n=287; 38.37\%), and slow functioning improvement (n=115; 15.37\%), respectively. Out of 12 tested factors, multinomial logistic regression showed that age, injury level, injury severity, and ventilator assistance were robust predictors that could distinguish between identified classes of functioning trajectories in the present sample. Conclusions: The current study establishes a foundation for future research on the course of functioning of individuals with SCI in initial rehabilitation by identifying classes of functioning trajectories. This supports the development of specifically tailored rehabilitation programs and prediction models, which can be integrated into clinical rehabilitation planning.}, language = {en} } @article{SenjuMukainoProdingeretal.2021, author = {Senju, Y and Mukaino, M and Prodinger, Birgit and Selb, M and Okouchi, Y and Mizutani, K and Suzuki, M and Yamada, S and Izumi, SI and Sonoda, S and Otaka, Y and Saitoh, E and Stucki, G}, title = {Development of a clinical tool for rating the body function categories of the ICF generic-30/rehabilitation set in Japanese rehabilitation practice and examination of its interrater reliability}, series = {BMC Medical Research Methodology}, volume = {21}, journal = {BMC Medical Research Methodology}, number = {1}, pages = {121}, year = {2021}, abstract = {Background: The International Classification of Functioning, Disability, and Health (ICF) Generic-30 (Rehabilitation) Set is a tool used to assess the functioning of a clinical population in rehabilitation. The ICF Generic-30 consists of nine ICF categories from the component "body functions" and 21 from the component "activities and participation". This study aimed to develop a rating reference guide for the nine body function categories of the ICF Generic-30 Set using a predefined, structured process and to examine the interrater reliability of the ratings using the rating reference guide. Methods: The development of the first version of the rating reference guide involved the following steps: (1) a trial of rating patients by several raters; (2) cognitive interviews with each rater to analyze the thought process involved in each rating; (3) the drafting of the rating reference guide by a multidisciplinary panel; and (4) a review by ICF specialists to confirm consistency with the ICF. Subsequently, we conducted a first field test to gain insight into the use of the guide in practice. The reference guide was modified based on the raters' feedback in the field test, and an inter-rater reliability test was conducted thereafter. Interrater agreement was evaluated using weighted kappa statistics with linear weights. Results: The first version of the rating reference guide was successfully developed and tested. The weighted kappa coefficient in the field testing ranged from 0.25 to 0.92. The interrater reliability testing of the rating reference guide modified based on the field test results yielded an improved weighted kappa coefficient ranging from 0.53 to 0.78. Relative improvements in the weighted kappa coefficients were observed in seven out of the nine categories. Consequently, seven out of nine categories were found to have a weighted kappa coefficient of 0.61 or higher. Conclusions: In this study, we developed and modified a rating reference guide for the body function categories of the ICF Generic-30 Set. The interrater reliability test using the final version of the rating reference guide showed moderate to substantial interrater agreement, which encouraged the use of the ICF in rehabilitation practice.}, language = {en} } @article{LiuReinhardtZhangetal.2019, author = {Liu, S. and Reinhardt, J.

Specific objectives were to analyze (1) interrater reliability, (2) convergent validity, (3) known group validity, and (4) predictive validity of the ICF Generic-6. Design Multicenter prospective cohort study. Setting Fifty hospitals from 20 provinces of Mainland China. Participants A total of 4510 patients from departments of rehabilitation, orthopedics, neurology, cardiology, pneumology, and cerebral surgery of the participating hospitals with different health conditions were included in this study. Intervention Not applicable. Main Outcome Measures The assessment was undertaken by nurses with ICF Generic-6 in combination with a numeric rating scale. Interrater reliability was evaluated with intraclass correlation coefficients (ICC). Convergent validity was evaluated with Spearman correlation coefficients between ICF Generic-6 and Medical Outcomes Short Form (SF)-12 items. Known group validity was examined by comparing discharge scores between different discharge destinations. Predictive validity was determined by using ICF Generic-6 baseline scores for estimating length of hospital stay with a loglogistic survival model with gamma shared frailty and cost of in-hospital treatment with a mixed effects generalized linear regression model of the gamma family. Results The interrater reliability of items and score of ICF Generic-6 was good with ICCs ranging from 0.67-0.87. ICF Generic-6 items were further correlated with respective SF-12 items. Discharge scores of patients differed significantly by discharge destination. The ICF Generic-6 admission score was a significant predictor of length of stay and treatment cost. Conclusions The ICF Generic-6 administered in combination with a 0-10 numeric rating scale is a reliable and valid tool for the collection of minimal information on functioning across various clinical settings.}, language = {en} } @article{MaritzPongpipatpaiboonMelvinetal.2019, author = {Maritz, R. and Pongpipatpaiboon, K. and Melvin, J.L. and Graves, D.E. and Prodinger, Birgit}, title = {Content comparison of the Spinal Cord Injury Model System Database to the ICF Generic Sets and Core Sets for spinal cord injury}, series = {Spinal Cord}, volume = {57}, journal = {Spinal Cord}, number = {12}, pages = {1023 -- 1030}, year = {2019}, abstract = {Study design Mapping of the National Spinal Cord Injury Model System (SCIMS) Database (NSCID) to the International Classification of Functioning, Disability and Health (ICF). Objectives To link the content of the latest two versions of the NSCID to the ICF; more specifically (1) to compare the content of the current NSCID 2016-2021 version to its predecessor (NSCID 2011-2016) using the ICF as a neutral reference framework, and (2) to compare the content contained in the NSCID 2016-2021 version with relevant ICF Sets. Setting The forms of the NSCID 2016-2021 and 2011-2016 versions were linked to the ICF and contrasted. Comparability of the current version of the NSCID with the ICF Core Set for Spinal Cord Injury (SCI) in the post-acute and long-term context and the two generic ICF sets— ICF Generic-7 and ICF Generic-30 was then examined. Methods ICF Linking Rules and descriptive statistics. Results The current NSCID 2016-2021 version covers functioning as classified in the ICF with 8 ICF categories more comprehensively than its predecessor does. More than 50\% of ICF categories contained in the two ICF Generic Sets were covered. The coverage of the brief ICF Core Sets for SCI by the NSCID 2016-2021 was more than 50\%, but the coverage of the comprehensive core sets was low. Results showed the best coverage in the ICF component Activities and Participation.

Reporting on ICF-based common metrics enables standardized documentation of functioning information in national health information systems. The objective of this methodological note on applying the ICF in rehabilitation is to demonstrate how to report functioning information collected with a data collection tool on ICF-based common metrics. We first specify the requirements for the standardized reporting of functioning information. Secondly, we introduce the methods needed for transforming functioning data to ICF-based common metrics. Finally, we provide an example. METHODS: The requirements for standardized reporting are as follows: 1) having a common conceptual framework to enable content comparability between any health information; and 2) a measurement framework so that scores between two or more clinical data collection tools can be directly compared. The methods needed to achieve these requirements are the ICF Linking Rules and the Rasch measurement model. Using data collected incorporating the 36-item Short Form Health Survey (SF-36), the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and the Stroke Impact Scale 3.0 (SIS 3.0), the application of the standardized reporting based on common metrics is demonstrated. RESULTS: A subset of items from the three tools linked to common chapters of the ICF (d4 Mobility, d5 Self-care and d6 Domestic life), were entered as "super items" into the Rasch model. Good fit was achieved with no residual local dependency and a unidimensional metric. A transformation table allows for comparison between scales, and between a scale and the reporting common metric. CONCLUSIONS: Being able to report functioning information collected with commonly used clinical data collection tools with ICF-based common metrics enables clinicians and researchers to continue using their tools while still being able to compare and aggregate the information within and across tools.}, language = {en} } @article{GrillStroblMuelleretal.2011, author = {Grill, E. and Strobl, R. and M{\"u}ller, Martin and Quittan, M. and Kostanjsek, N. and Stucki, G.}, title = {ICF Core Sets for early post-acute rehabilitation facilities}, series = {Journal of rehabilitation medicine}, journal = {Journal of rehabilitation medicine}, number = {43(2)}, editor = {Foundation of Rehabilitation Information,}, year = {2011}, abstract = {Objective: To identify candidate categories for International Classification of Functioning, Disability and Health (ICF) Core Sets for the reporting and measurement of functioning in patients in early post-acute rehabilitation facilities.

UEMS PRM Workshop in Nottwil, Switzerland, January 2016.PRM physicians representatives from 12 European countries, as well as Israel and Japan, mostly delegates of UEMS PRM Section and Board, and experts with other rehabilitation professional backgrounds.Participants were divided into 6 working groups and asked to specify what functioning aspects would be essential to document using the available ICF sets for the identified rehabilitation services contained in the newly developed service classification (ICSO-R): acute, post-acute and long-term rehabilitation services. The 7 ICF Generic and 23 Rehabilitation Set categories were confirmed as well as specific health condition categories for acute rehabilitation services (mobile team), for postacute rehabilitation services (general outpatient rehabilitation, musculoskeletal and neurological rehabilitation, as well as specialized SCI rehabilitation), and for long-term rehabilitation services (day clinic and rehabilitation provided in the community). While general principles of the CLAS were defined, the need to align the CLAS for a specific service, as well as across services along the continuum of care was highlighted. All groups deliberated on this topic; however, no conclusive statement was presented yet.The groups recognized a need for a systematic effort to identify data collection tools currently used.CLASs will serve in the future to ensure that functioning information is systematically and consistently collected across services, and thus respond also to various global reports and initiatives which stress the need for improving data collection on people's functioning.}, language = {en} }
