Objectives To describe the development, validation and inter-rater reliability of an instrument to measure quality patient decision support technologies (decision aids). Design Scale development study, involving construct, item scale testing. Setting There has been increasing use – adjuncts discussions clinicians have with patients about difficult decisions. A global interest in developing these interventions exists among both for-profit not-for-profit organisations. It is therefore...
Objective. The IPDAS Collaboration has developed a checklist and an instrument (IPDASi v3.0) to assess the quality of patient decision aids (PDAs) in terms their development process shared decision-making design components. Certification PDAs is growing interest US elsewhere. We report modified Delphi consensus agree on IPDASi (v3.0) items that should be considered as minimum standards for PDA certification, inclusion refined (v4.0). Methods. A 2-stage voting standards. Item scores...
Background Research needs to be reported transparently so readers can critically assess the strengths and weaknesses of design, conduct, analysis studies. Reporting guidelines have been developed inform reporting for a variety study designs. The objective this was identify whether there is need develop guideline survey research. Methods Findings We conducted three-part project: (1) systematic review literature (including "Instructions Authors" from top five journals 33 medical specialties 15...
Health administrative data is increasingly being used for chronic disease surveillance. This study explored agreement between and survey ascertainment of seven key diseases, using individually linked from a large population individuals in Ontario, Canada. All adults who completed any one three cycles the Canadian Community Survey (2001, 2003 or 2005) agreed to have their responses provincial health were included. The sample included 85,549 persons. Previously validated case definitions...
Optimal performance is critical for decision-making tasks from medicine to autonomous driving, however common measures may be too general or specific. For binary classifiers, diagnostic tests prognosis at a timepoint, such as the area under receiver operating characteristic curve, precision recall are because they include unrealistic decision thresholds. On other hand, accuracy, sensitivity F1 score single threshold that reflect an individual probability predicted risk, rather than range of...
Behaviours such as smoking, poor diet, physical inactivity, and unhealthy alcohol consumption are leading risk factors for death. We assessed the Canadian burden attributable to these behaviours by developing, validating, applying a multivariable predictive model of all-cause death.A algorithm 5 y death-the Mortality Population Risk Tool (MPoRT)-was developed validated using 2001 2008 Community Health Surveys. There were approximately 1 million person-years follow-up 9,900 deaths in...
<b>Background:</b> The Canadian CT Head Rule was developed to allow physicians be more selective when ordering computed tomography (CT) imaging for patients with minor head injury. We sought evaluate the effectiveness of implementing this validated decision rule at multiple emergency departments. <b>Methods:</b> conducted a matched-pair cluster-randomized trial that compared outcomes 4531 injury during two 12-month periods (before and after) hospital departments in Canada, six which were...
ObjectivesTo establish if proprietary status (ie, for-profit or not-for-profit) is associated with mortality and hospitalizations among publicly funded long-term care (nursing) homes.MethodsWe conducted a retrospective cohort study of new admissions in 640 facilities Ontario, Canada (384 for-profit, 256 not-for-profit). A population-based 53,739 incident into between January 1, 2010, March 2012, was observed. We measured adjusted rates hospital mortality, per 1000 person-years (PY)...
Clinical decision rules (CDRs) are tools designed to help clinicians make bedside diagnostic and therapeutic decisions. The development of a CDR involves three stages: derivation, validation, implementation. Several criteria need be considered when designing evaluating the results an implementation trial. In this article, authors review studies effect four CDRs: Ottawa Ankle Rules, Knee Rule, Canadian C-Spine CT Head Rule. Four demonstrated that CDRs in emergency department (ED) safely...
The prevalence of multiple chronic diseases is increasing and a common problem for primary health care providers. This study sought to determine the patient system burden among adults in Ontario, Canada, with focus on ambulatory (outpatient specialist services). population-based used linked administrative data from Canada. Individuals, aged 20 years or older, who had valid card, were included. Validated case definitions identify persons at least one following nine diseases: diabetes,...
Cluster randomized trials (CRTs) pose ethical challenges for investigators and ethics committees. This study describes the views experiences of CRT researchers with respect to: (1) in CRTs; (2) review process (3) need comprehensive guidelines CRTs. Descriptive qualitative analysis interviews conducted a purposive sample 20 experienced researchers. Informants expressed concern over potential bias that may result from requirements to obtain informed consent research participants suggested...
Decision aids are evidence based tools that assist patients in making informed values-based choices and supplement the patient-clinician interaction. While there is to show decision improve key indicators of patients' quality, relatively little known about physicians' acceptance or factors influence their use them. The purpose this study was describe perceptions three aids, expressed intent them, subsequent We conducted a cross-sectional survey random samples Canadian respirologists, family...
