Patient perceptions of participation in emergency medicine research projects.

Objective: To determine if ED research reflects patient expectations.

Method: A cross-sectional ED patient survey.

Results: Three hundred and nine (98.

Risk variables associated with abnormal calcium, magnesium and phosphate levels among emergency department patients.

Objective: The utility of calcium, magnesium and phosphate measurement in the ED is limited. We aimed to determine clinical risk variables for abnormal levels of these electrolytes in order to inform the development of an ordering guideline.

Methods: We performed a retrospective, observational study of patients who presented to a tertiary referral ED between January and June 2017.

Utility of calcium, magnesium and phosphate testing in the emergency department.

Objective: To determine how frequently calcium (Ca), magnesium (Mg) and phosphate (PO ) tests change ED patient management.

Methods: We undertook a retrospective observational study in an Australian tertiary referral ED. We enrolled adult patients (aged ≥18 years) who presented between 1 January and 30 June 2017 and who had a serum Ca, Mg or PO test ordered and completed during their ED stay.
