Although the application of patient-specific instruments (PSI) for total knee arthroplasty (TKA) increases the cost of the surgical procedure, PSI may reduce operative time and improve implant alignment, which could reduce the number of revision surgeries. We report our experience with TKA using PSI techniques in 120 patients from March to December 2014. PSI for TKA were created from data provi...

Key points Many gastrointestinal diseases are symptomdriven, so the patient’s perspective is particularly important in this area. Patient-reported outcomes (PROs) provide essential information that objective measures and clinician assessment may fail to capture. PROs can be measured in a scientific, reliable, and valid manner. Generic, disease-specific and treatmentspecific PRO instruments exis...

Surgical departments are increasingly put under pressure to improve services, cut waiting lists, increase efficiency and save money. At a district general hospital in the west-midlands we approached the challenge of improving efficiency and optimising the services available in our orthopaedic theatres. Data was collected on: anaesthetic start times, operation start and finish times, and reasons...

The assessment of clinical outcomes is an emerging topic within athletic training and the general health care system. Clinicians, educators, and researchers interested in gaining foundational knowledge related to clinical outcomes assessment will find the AO Handbook: Musculoskeletal Outcomes Measures and Instruments, second expanded edition, to be an easy-to-follow and useful resource. Expande...

INTRODUCTION Online communities contain a wealth of information containing unsolicited patient experiences that may go beyond what is captured by guided surveys or patient-reported outcome (PRO) instruments used in clinical settings. This study described patient experiences reported online to better understand the day-to-day disease burden of ankylosing spondylitis (AS). METHODS Unguided, Eng...

Knee arthroplasty has been indicated with growing frequency, especially over the last decade. Its success depends on various factors, such as component design, the quality of the material used to make the component, the manufacturing process, adequate patient selection and the surgical technique. Most of these are developed by the surgical material and implant industry, and the evolution of the...

The purpose of this study was to systematically review the instruments used to obtain anesthesia-specific patient satisfaction data and to determine the degree to which each instrument controlled for measurement error bias, such as poor survey design. By using an assessment and evaluation tool developed for the present study that held proven internal reliability and construct validity, we analy...

BACKGROUND Observed differences between results obtained from comparison of instruments used to measure international normalized ratio (INR) have been higher than expected from the imprecision of the instruments. In this study the variation of these differences was divided into subcomponents, and each of the subcomponents was estimated. METHODS Blood samples were collected at 4 different pati...

STUDY DESIGN A prospective and retrospective cross-sectional cohort analysis. OBJECTIVE The aim of this study was to show that Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive testing (CAT) assessments for physical function and pain interference can be efficiently collected in a standard office visit and to evaluate these scores with scores from previously v...
