Outcome measures
Primary outcome
The diagnostic accuracy of the NTS will be analyzed in terms of sensitivity, specificity, positive and negative predictive values of the urgency allocation (high; U1-U2, and low; U3-U5) on the outcomes ACS, and TIA/stroke.
Secondary outcome
In addition, a) sensitivity analyses with inclusion of other emergency cases that can result in chest discomfort such as pulmonary embolism, acute heart failure, and thoracic aortic dissection, and other emergency cases that can result in neurological symptoms such as subarachnoid hemorrhage (SAH) and epilepsy, and b) pre-specified subgroup analyses for gender and age will be performed.
Background summary
The “Netherlands Triage Standard” (NTS) is the most often used digital decision support system for telephone triage at out-of-hours primary care services (OHS-PC) in the Netherlands. The aim of the NTS is to guarantee accessible, efficient and safe care. However, the NTS has only been validated against expert opinion. Studies that assessed the clinical validity in primary care setting are lacking. In the Safety First study we want to describe, understand and improve the diagnostic process, urgency allocation and safety of patients suspected of an acute cardiovascular disease.
The Safety First study is a cross-sectional study in which 3000 telephone triage recordings will be analyzed and information on patient and call characteristics, e.g. history taking and triage information is collected. The patients' own general practitioners are contacted about the final diagnosis. We included recordings of patients with symptoms of chest discomfort and neurological deficit. With multivariable logistic regression analyses the diagnostic accuracy of symptoms and patient characteristics will be analyzed in terms of sensitivity, specificity, positive and negative predictive values with respectively urgency level, and ACS and TIA/stroke as outcomes.
