Patient location at time of STEMI
Name Location_STEMI
Chapter MINAP/Clinical features and investigations
Definition
The purpose of this field is to permit identification of STE MI not originating in the community, in order that such patients can be excluded, where appropriate, from call to needle and call to balloon analyses.

1 Onset of STEMI while patient not in hospital (STE on first ECG) This implies that ST elevation was found on first ECG performed in an ambulance or other medical facility (GP surgery etc) before arrival at the first hospital or on the first ECG recorded in hospital for a self presenter. If no ECG was taken prior to admission and first ECG recorded in hospital shows ST elevation then it should be assumed that STEMI developed before reaching hospital. This option should also be selected where an ECG was not considered diagnostic before admission, but STE is diagnosed on arrival at A&E.
2 STE first recorded on a subsequent ECG in, (or before arrival at) a non-interventional hospital The word subsequent applies to any ECG taken after an initial non-diagnostic ECG was performed at the non-interventional hospital. This group of patients will have arrived in hospital without a diagnosis of STE MI, and then develop ST segment elevation after hospital admission. The subsequent ECG may be at any time after admission to hospital. This option covers a spectrum from patients initially presenting with features consistent with ACS who go on to develop STEMI through to patients who are admitted for some other condition who develop STEMI while in hospital.
3 STE first recorded on a subsequent ECG in, (or before arrival at) the interventional hospital The word subsequent applies to any ECG taken after an initial non-diagnostic ECG was performed at the interventional hospital. This group of patients will have arrived in hospital without a diagnosis of STE MI, and then develop ST segment elevation after hospital admission. The subsequent ECG may be at any time after admission to hospital. This option covers a spectrum from patients initially presenting with features consistent with ACS who go on to develop STEMI through to patients who are admitted for some other condition who develop STEMI while in hospital.
