the development of a disease specific quality of life Measurement Tool for osteoarthritis of the shoulder the western ontario osteoarthritis of the shoulder woos index
Osteoarthritis and Cartilage, 2001Co-Authors: Sharon Griffin, Alexandra KirkleyAbstract:Abstract Objective The purpose of this study was to develop and validate a disease-specific quality of life Measurement Tool for osteoarthritis (OA) of the shoulder. Methods An instrument which could be used as the primary outcome measure in clinical trials involving patients with OA of the shoulder was developed using a specific methodological protocol: (1) identification of a specific patient population; (2) item generation; (3) item reduction; (4) pre-testing of the prototype questionnaire and (5) determining the validity, reliability and responsiveness of the final questionnaire. Results The final instrument contains 19 items, each with a visual analog response option for the four domains (six questions for pain and physical symptoms, five questions for sport, recreation and work, five questions for lifestyle function and three questions for emotional function). Ten of the 19 questions had not been identified previously on other shoulder Measurement Tools. The instrument proved to be valid by demonstrating predicted correlations with previously published shoulder measures, global health status measure and range of motion. The new instrument was also more responsive than other shoulder Measurement Tools, a global health status measure and range of motion. Conclusions Since the patient's own perception of changes in health status is the most important indicator of the success of treatment we suggest that this Measurement Tool be used as the primary outcome in clinical evaluation of various treatments for OA of the shoulder and monitoring patients over time.

the development and evaluation of a disease specific quality of life Measurement Tool for shoulder instability the western ontario shoulder instability index wosi
American Journal of Sports Medicine, 1998Co-Authors: Alexandra Kirkley, Sharon Griffin, Heidi Mclintock, Linda NgAbstract:The purpose of this study was to develop a valid, reliable, and responsive disease-specific quality of life Measurement Tool for patients with shoulder instability. Development included 1) identification of a specific patient population; 2) generation of issues specific to the “disease” (“items”) from reviewing the literature, interviewing health caregivers, and interviewing patients representing all demographics, disease type and severity, and treatments; 3) item reduction using patient-generated frequency-importance products and correlation matrices; and 4) pretesting the prototype instrument on 2 groups of 10 patients. The final instrument, the Western Ontario Shoulder Instability Index, has 21 items representing 4 domains. The instrument attributes (validity, reliability, and responsiveness) were evaluated. Construct validation demonstrated that this index correlated predictably with other measures. Reliability was very high at 2 weeks and 3 months, and the index was more responsive (sensitive to chan...

DiameterJ: A validated open source nanofiber diameter Measurement Tool
Biomaterials, 2015Co-Authors: Nathan A. Hotaling, Hermanus Kriel, Kapil Bharti, Carl G. SimonAbstract:Despite the growing use of nanofiber scaffolds for tissue engineering applications, there is not a validated, readily available, free solution for rapid, automated analysis of nanofiber diameter from scanning electron microscope (SEM) micrographs. Thus, the goal of this study was to create a user friendly ImageJ/FIJI plugin that would analyze SEM micrographs of nanofibers to determine nanofiber diameter on a desktop computer within 60 s. Additional design goals included 1) compatibility with a variety of existing segmentation algorithms, and 2) an open source code to enable further improvement of the plugin. Using existing algorithms for centerline determination, Euclidean distance transforms and a novel pixel transformation technique, a plugin called "DiameterJ" was created for ImageJ/FIJI. The plugin was validated using 1) digital synthetic images of white lines on a black background and 2) SEM images of nominally monodispersed steel wires of known diameters. DiameterJ analyzed SEM micrographs in 20 s, produced diameters not statistically different from known values, was over 10-times closer to known diameter values than other open source software, provided hundreds of times the sampling of manual Measurement, and was hundreds of times faster than manual assessment of nanofiber diameter. DiameterJ enables users to rapidly and thoroughly determine the structural features of nanofiber scaffolds and could potentially allow new insights to be formed into fiber diameter distribution and cell response.

Dataset for the validation and use of DiameterJ an open source nanofiber diameter Measurement Tool
Data in Brief, 2015Co-Authors: Nathan A. Hotaling, Hermanus Kriel, Kapil Bharti, Carl G. SimonAbstract:DiameterJ is an open source image analysis plugin for ImageJ. DiameterJ produces ten files for every image that it analyzes. These files include the images that were analyzed, the data to create histograms of fiber radius, pore size, fiber orientation, and summary statistics, as well as images to check the output of DiameterJ. DiameterJ was validated with 130 in silico-derived, digital, synthetic images and 24 scanning electron microscope (SEM) images of steel wire samples with a known diameter distribution. Once validated, DiameterJ was used to analyze SEM images of electrospun polymeric nanofibers, including a comparison of different segmentation algorithms. In this article, all digital synthetic images, SEM images, and their segmentations are included. Additionally, DiameterJ's raw output files, and processed data is included for the reader. The data provided herein was used to generate the figures in DiameterJ: A Validated Open Source Nanofiber Diameter Measurement Tool [1], where more discussion can be found.

utilizing a modified care coordination Measurement Tool to capture value for a pediatric outpatient parenteral and prolonged oral antibiotic therapy program
Journal of the Pediatric Infectious Diseases Society, 2018Co-Authors: Louise E Vaz, Richard C. Antonelli, Cindi L Farnstrom, Kimberly Felder, Judith Guzmancottrill, Hannah RosenbergAbstract:Background Outpatient parenteral or prolonged oral antibiotic therapy (OPAT) programs reduce inpatient healthcare costs by shifting care to outpatient settings. Care coordination (CC) is a necessary component to successfully transition patients. Our objective was to assess outcomes of provider time spent on nonreimbursable CC activities in a pediatric OPAT program. Methods We used a qualitative feasibility pilot design and modified the Care Coordination Measurement Tool. We captured nonreimbursable CC activity and associated outcome(s) among pediatric patients enrolled in OPAT from March 1 to April 30, 2015 (44 work days) at Doernbecher Children's Hospital. We generated summary statistics for this institutional review board-waived QI project. Results There were 154 nonreimbursable CC encounters conducted by 2 infectious diseases (ID) providers for 29 patients, ages 17 months-15 years, with complex infections. Total estimated time spent on CC was 54 hours, equivalent to at least 6 workdays. Five patients with complex social issues used 37% of total CC time. Of 129 phone events, 38% involved direct contact with families, pharmacies (13%), primary care providers (13%), and home health nursing (11%). Care coordination prevented 10 emergency room (ER) visits and 2 readmissions. Care coordination led to 16 additional, not previously scheduled subspecialist and 13 primary care visits. The OPAT providers billed for 32 clinic visits during the study period. Conclusions Nonreimbursable CC work by OPAT providers prevented readmissions and ER visits and helped facilitate appropriate healthcare use. The value of pediatric OPAT involvement in patient care would have been underestimated based on reimbursable ID consultations and clinic visits alone.

care coordination for children and youth with special health care needs a descriptive multisite study of activities personnel costs and outcomes
Pediatrics, 2008Co-Authors: Richard C. Antonelli, Christopher J Stille, Donna M AntonelliAbstract:OBJECTIVES. Objectives included testing use of the care-coordination Measurement Tool in pediatric primary care practices; describing care-coordination activities for children and youth that occur in primary care practices; assessing the relationship of care-coordination activities in the medical home with outcomes related to resource use; and measuring the direct personnel costs of care-coordination activities. METHODS. Six general pediatric practices were selected, representing a diverse range of sizes, locations, patient demographics, and care-coordination activity model types. The care-coordination Measurement Tool was used over a period of 8 months in 2003 to record all of the nonreimbursable care-coordination activity encounters performed by any office-based personnel. The Tool enabled recording of activities, resources-use outcomes, and time. Cost of personnel performing care-coordination activities was derived by extrapolation from the time spent. RESULTS. Care-coordination activity services were used by patients of all complexity levels. Children and youth with special health care needs with acute-onset, family-based psychosocial problems experienced 14% of the care-coordination activity encounters and used 21% of the care-coordination activities minutes. Children and youth without special health care needs, without complicating family psychosocial problems, received 50% of the encounters and used 36% of the care-coordination activity minutes. The average cost per care-coordination activity encounter varied from $4.39 to $12.86, with an overall mean of $7.78. A principal cost driver seemed to be the percentage of care-coordination activities performed by physicians. Office-based nurses prevented a large majority of emergency department visits and episodic office visits. CONCLUSIONS. Care-coordination activity was assessed at the practice level, and the care-coordination Measurement Tool was used successfully during the operations of typical, pediatric, primary care settings. The presence of acute, family-based social stressors was a significant driver of need for care-coordination activities. A high proportion of dependence on care-coordination performed by physicians led to increased costs. Office-based nurses providing care coordination were responsible for a significant number of episodes of avoidance of higher cost use outcomes.
