Description of intervention(s) / exposure
No intervention/exposure. This is a retrospective audit study which will review all Cardiac Implanted Electronic Device checks performed in the Royal Adelaide Hospital Emergency Department over a defined twelve month period to assess how often these checks identify relevant clinical data for the each patient's presentation. The audit period will be 4th September 2016 to 3rd September 2017, inclusive.

Outcomes
Primary outcome [1] 319752 0
Incidence of Remarkable Issues (RI) for all checks performed in the ED over the audit period. The composite endpoint of "Remarkable Issues" is comprised of;
a) CIED malfunction which required urgent reprogramming (ie; lead dislodgment or battery issue), or;
b) Significant arrhythmia responsible for presentation, or;
d) Tachyarrhythmia therapy intervention since last device check (ie; AICD shock or Anti Tachycardia Pacing).

Statistical methods / analysis
All data will be analyzed retrospectively. The nominal data will be presented as number of events (n) and percentage (%). Normally distributed continuous data will be expressed as mean ± standard deviation. The difference between groups will be analyzed using chi-squared comparisons for the nominal data and the normal continuous data tested with unpaired t-tests between groups. Clinical predictors of remarkable issues will be evaluated.

Summary
Brief summary
The purpose of this study is to investigate the outcomes of Cardiac Implantable Electronic Device (CIED) interrogations performed in the Emergency Department (ED). Patients who present to the Royal Adelaide Hospital’s (RAH) ED whom have an Implanted Cardiac Electronic Device (CIED) currently have their device interrogated upon request by the attending ED physician. These device interrogations are performed by Cardiac Physiologists, often requiring call-backs at the expense of the hospital, who use specialised computer systems which can interact with the device by telemetry. The performance of the CIED can be assessed during these interrogations to exclude device malfunction as a contributing factor to the patient’s clinical presentation. Furthermore, clinical data trends stored in the device can assist in diagnostics for the ED physician. It is not known how frequently significant issues are detected from these device checks. We hypothesize that there is a low yield of significant issues identified by CIED checks performed in the ED. The outcomes of this study can be used to develop evidence-based triaging methods to reduce the number of unnecessary checks and call-backs being performed.
