BACKGROUND A multi-domain suite of instruments has been developed by the interRAI research collaborative to support assessment and care planning in mental health, aged care and disability services. Each assessment instrument comprises items common to other instruments and specialized items exclusive to that instrument. This study examined the reliability of the items from five instruments suppo...
RATIONALE Treatment and prognoses of diffuse parenchymal lung diseases (DPLDs) varies by diagnosis. Obtaining a uniform diagnosis among observers is difficult. OBJECTIVES Evaluate diagnostic agreement between academic and community-based physicians for patients with DPLDs, and determine if an interactive approach between clinicians, radiologists, and pathologists improved diagnostic agreement...
BACKGROUND Many studies have attempted to identify histologic features that help to distinguish atypical hyperplasia from hyperplasia without atypia and well-differentiated endometrioid carcinoma of the endometrium; however, few have evaluated the reproducibility of these diagnoses. METHODS Five pathologists independently reviewed 100 endometrial curettage specimens chosen to represent the sp...
results with respect to the inter-reliability testing, there was a high level of agreement between reviewers applying the instrument in the admissions criteria and days of stay. overall agreement was > 77%; also specific inappropriate agreement and specific appropriate agreement were > 61%, and > 72%, respectively. regarding the validity of the testing, the instrument had a sensitivity of > 0.7...
The objective of the study was to assess inter-rater reliability of one palpation and six pain provocation tests for pain of sacroiliac origin. The sacroiliac joint (SIJ) is a potential source of low back and pelvic girdle pain. Diagnosis is made primarily by physical examination using palpation and pain provocation tests. Previous studies on the reliability of such tests have reported inconclu...
The SAS system V.8 implements the computation of unweighted and weighted kappa statistics as an option in the FREQ procedure. A major limitation of this implementation is that the kappa statistic can only be evaluated when the number of raters is limited to 2. Extensions to the case of multiple raters due to Fleiss (1971) have not been implemented in the SAS system. A SAS macro called MAGREE.SA...
The aim of our study was to develop a Korean rheumatic diseases-screening questionnaire. The questionnaire was constructed based on American College of Rheumatology criteria for rheumatic diseases and a connective tissue diseases screening questionnaire. Two groups of patients were selected and completed the questionnaire: (i) those with osteoarthritis (n=46), rheumatoid arthritis (n=52), syste...
BACKGROUND AND PURPOSE We sought to assess the relationship between 2 simple questions on recovery (question 1: do you feel that you have made a complete recovery from your stroke?) and dependency (question 2: do you require help from another person for everyday activities?) and the Barthel Index (BI) and Oxford Handicap Scale (OHS), as well as the relationship between BI and OHS, in a large nu...
OBJECTIVE This study examined the concurrent diagnostic validity of the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) across alcohol and drug dependencies, major depression, anxiety disorders and ASPD. The Schedule for Clinical Assessment in Neuropsychiatry (SCAN) was selected as the comparison instrument because it arises from a different tradition and uses a different form...
Background: Many methods under the umbrella of inter-rater agreement (IRA) have been proposed to evaluate how well two or more medical experts agree on a set outcomes. The objective this work was assess key IRA statistics in context multiple raters with binary Methods: We simulated responses several (2–5) 20, 50, 300, and 500 observations. For each combination observations, we estimated expecte...
