Background. As patients become more involved in health care decisions, there may be greater opportunity for decision regret. The authors could not find a validated, reliable tool measuring regret after decisions. Methods. A5- item scale was administered to 4 patient groups making different Convergent validity deter- mined by examining the scale's correlation with satisfaction measures, decisional conflict, and outcome measures. Results. showed good internal consistency (Cronbach's = 0.81...
Consensus group methods are widely used in research to identify and measure areas where incomplete evidence exists for decision-making. Despite their widespread use, these often inconsistently reported. Using examples from the three most commonly methods, Delphi, Nominal Group RAND/UCLA; this paper associated Guide aim describe highlight common weaknesses methodology reporting. The outlines a series of recommendations assist researchers using consensus providing comprehensive description...
Most assessment of surgical trainees is based on measures knowledge, with limited evaluation their competence to actually perform various procedures. In this study, the authors evaluated a tool they designed assess trainee's an entire procedure independently, regardless type or postgraduate year (PGY).In phase 1, Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) was piloted in University Ottawa's Division Orthopaedic Surgery. 2, refined 11-item (8 items rated 5-point competency...
Diagnostic errors are thought to arise from cognitive biases associated with System 1 reasoning, which is rapid and unconscious. The primary hypothesis of this study was that the instruction be slow thorough will have no advantage in diagnostic accuracy over proceed rapidly.Participants were second-year residents who volunteered after they had taken Medical Council Canada (MCC) Qualifying Examination Part II. Participants tested at three Canadian medical schools (McMaster, Ottawa, McGill)...
There has been difficulty designing medical school admissions processes that provide valid measurement of candidates' nonacademic qualities.To determine whether students deemed acceptable through a revised protocol using 12-station multiple mini-interview (MMI) outperform others on the 2 parts Canadian national licensing examinations (Medical Council Canada Qualifying Examination [MCCQE]). The MMI process requires candidates to rotate brief sequential interviews with structured tasks and...
Psychologists theorize that cognitive reasoning involves two distinct processes: System 1, which is rapid, unconscious, and contextual, 2, slow, logical, rational. According to the literature, diagnostic errors arise primarily from 1 reasoning, therefore they are associated with rapid diagnosis. This study tested whether accuracy shorter or longer times diagnosis.Immediately after 2010 administration of Medical Council Canada Qualifying Examination (MCCQE) Part II at three test centers,...
Previous observations have shown that binding of growth hormone to its receptor leads activation transcription factors via a mechanism involving phosphorylation on tyrosine residues. In order establish whether the prolactin-activated factor Stat 5 (mammary gland factor) is also activated by hormone, nuclear extracts were prepared from COS-7 cells transiently expressing transfected and cDNA. Gel electrophoresis mobility shift analyses revealed hormone-dependent presence specific DNA-binding...
The extracellular domain of the rabbit growth hormone (GH) receptor has previously been shown to be associated with nucleus. However, in this species GH binding protein (BP) is derived by proteolytic cleavage full-length receptor, and thus distinction between BP difficult. intracellular required for GH-stimulated function. Thus a direct nuclear function would presumably require We have therefore characterized rat based on their distinct antigenic identity. show, vivo, that nucleus, including...
Construct: The Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) is a 9-item surgical evaluation tool designed to assess technical competence in trainees using behavioral anchors. Background: initial development of the O-SCORE produced evidence for valid results. Further work required determine if use single surgeon or an unblinded rater introduces bias. In addition, relationship other currently used assessment tools should be explored provide validity related measures. We have...
Others have suggested that increased time pressure, sometimes caused by interruptions, may result in diagnostic errors. The authors previously found, however, pressure alone does not errors, but they did test the effect of interruptions. It is unclear whether experience modulates combined effects and This study investigated level affect accuracy response time.In October 2012, 152 residents were recruited at five Medical Council Canada Qualifying Examination Part II sites. Forty-six emergency...
Context Progress tests, in which learners are repeatedly assessed on equivalent content at different times their training and provided with feedback, would seem to lend themselves well a competency-based framework, requires more frequent formative assessments. The objective structured clinical examination (OSCE) progress test is relatively new form of assessment that used assess the progression skills. purpose this study was establish further evidence for use an OSCE by demonstrating...
Consensus group methods such as the Nominal Group Technique (NGT) and Delphi method are commonly used in research to elicit synthesize expert opinions when evidence is lacking. Traditionally, NGT involves a face-to-face interaction. However, due COVID-19 pandemic, many in-person meetings have moved online settings. It unclear what extent has been undertaken virtual The overarching aim of this scoping review explore use research. Our specific objectives answer following questions: To...
Growth hormone activates gene transcription of the serine protease inhibitors (SPI) 2.1 and 2.2 by an unknown mechanism. In order to define promoter regions responsible for this effect characterize factors involved, we have performed gel electrophoresis mobility shift assays on nuclear extracts from cell lines transfected with growth receptor cDNA. We identified a 9-base pair DNA element, SPI-GLE 1, which forms complex proteins following activation which, when placed upstream minimal...
Although concern has been raised about the value of clinical evaluation reports for discriminating among trainees, there have few efforts to formalise dimensions and qualities that distinguish effective versus less useful styles form completion.Using brainstorming a modified Delphi technique, focus group determined key features high-quality completed reports. These were used create rating scale evaluate quality The was pilot-tested locally; results psychometrically analysed modify scale....
Background. Clinical decision rules can benefit clinicians, patients, and health systems, but they involve considerable up-front development costs must be acceptable to the target audience. No existing instrument measures acceptability of a rule. The current study validated such an instrument. Methods. authors administered Ottawa Acceptability Decision Rules Instrument (OADRI) via postal survey emergency physicians from 4 regions (Australasia, Canada, United Kingdom, States), in context 2...
to help reduce pressure on faculty staff, medical students have been used as raters in objective structured clinical examinations (OSCEs). There are few studies regarding their ability complete checklists and global rating scales, a paucity of data provide feedback junior colleagues. The objectives this study were: (i) compare expert examiner (FE) student-examiner (SE) assessment students' (candidates') performances formative OSCE; (ii) assess SE provided candidates, (iii) seek opinion...
