- OBJECTIVE: To describe the benefits and pitfalls of educational campaigns designed to reduce the delay between the onset of acute myocardial infarction (AMI) and its treatment. METHODS: All seven educational campaigns reported between 1982 and 1994 were evaluated. RESULTS: The impact on delay time ranged from a reduction of patient decision time by 35% to no reduction. One study reported a sustained reduction that resulted in the delay time being halved during the three years after the campaign. The use of ambulances did not increase. Only one study reported that survival was unaffected. There was a temporary increase in the numbers of patients admitted to the emergency department with non-cardiac chest pain in the initial phase of educational campaigns. CONCLUSION: The challenge of shortening the delay between the onset of infarction and the start of treatment remains. The campaigns so far have not been proved to be worthwhile and it is not certain that further campaigns will do better. New media campaigns should be run to establish whether a different type of message is more likely to change the behaviour of people in this life-threatening situation.

- OBJECTIVES: To explore factors associated with delay time prior to hospital admission and in hospital amongst acute myocardial infarction (AMI) patients with particular emphasis on the delay time to the administration of thrombolytic therapy. METHODS: During a 6-year period we prospectively computerized pre-hospital and in-hospital time intervals for AMI patients admitted to the coronary care unit (CCU) direct from the emergency department (ED) or via paramedics, at Sahlgrenska Hospital, Göteborg, Sweden. RESULTS: Pre-hospital delay: independent predictors of a prolonged delay were increased age (P = 0.0007), female sex (P = 0.02) and a history of hypertension (P = 0.03). For AMI patients who received thrombolytic treatment and the only independent predictor of a prolonged delay was increased age (P = 0.005). In-hospital delay: for all AMI patients independent predictors of a prolonged delay were prolonged pre-hospital delay (P < 0.0001), increased age (P = 0.03) and a history of angina (P = 0.002), hypertension (P = 0.01) and diabetes (P = 0.01). For thrombolytic treated AMI patients independent predictors of a prolonged delay were prolonged pre-hospital delay (P < 0.0001), female sex (P = 0.02) and a history of diabetes (P = 0.02). CONCLUSION: Risk factors for both pre-hospital and hospital delay time could in AMI be defined although slightly different. Two factors appeared for both, i.e. increasing age and a history of hypertension.

- The aim of this study was to describe the possibility of influencing components of hospital delay time within the emergency department (ED) among patients with ST-elevation on the initial electrocardiogram (ECG). Nurses recorded seven patient time points: (1) ED admission; (2) ECG recording; (3) decision by nurse/ED physician; (4) cardiologist ED arrival; (5) decision of coronary care unit (CCU) admission; (6) ED departure; (7) CCU arrival. After special training in ECG, nurses in the ED were subsequently delegated to send patients directly to the CCU if showing ST-elevation on the admission ECG without contacting either the physician in ED or the cardiologist on call (intervention). Delay times between hospital admission and admission to the CCU were evaluated during the 9 months prior to and during the 6 months after the start of this intervention. Fifty patients (66% men) participated in the first study during 3 months (prior to intervention). Patients with suspected or confirmed acute myocardial infarction (AMI) in the ED had a median delay time from ED arrival to CCU arrival of 55.5 minutes (34.5 minutes for patients with confirmed AMI; ST elevation on admission). Time interval from decision to admit to CCU and ED departure was an average of 31% of the total delay. A mean of 21% of total delay occurred between ED decision to cardiologist arrival, and 19% during the time interval from cardiologist ED arrival until decision to CCU admission. Among patients receiving thrombolysis, the median delay time from hospital admission to CCU admission was reduced from 40 minutes during the 9 months prior to start of the intervention (nurses sending patients directly to the CCU) to 22 minutes during the 6 months thereafter (p = 0.02). The largest proportion of hospital delay components for acute coronary syndrome patients occurred between the cardiologist's decision to admit to the CCU and departure from the ED, and the interval following the decision by the nurse or physician to the cardiologist ED arrival. When nurses were delegated to transfer patients with ST-elevation on admission directly to the CCU without contacting a physician, the delay time from ED admission to CCU admission was reduced by nearly 50%.
