- The Utstein registry template stress recording of out-of-hospital cardiac arrest (OHCA) location and suggest eight data options with additional subcategories. The subjectivity in categorization of OHCA locations by emergency medical services (EMS) makes objective regional and international comparisons hard.

- Objective: To describe changes in the epidemiology of out-of-hospital cardiac arrest in Sweden with the emphasis on the younger age groups.Design: Prospective observational study. Setting: Sweden.Patients: Patients were recruited from the Swedish Registry of Cardiopulmonary Resuscitation from 1990 to 2012. Only non-crew-witnessed cases were included.Intervention: Cardiopulmonary resuscitation.Measurement and Main Results: The endpoint was 30-day survival. Cerebral function among survivors was estimated according to the cerebral performance category scores. In all, 50,879 patients in the survey had an out-of-hospital cardiac arrest, of which 1,321 (2.6%) were 21 years old or younger and 1,543 (3.0%) were 22-35 years old. On the basis of results from 2011 and 2012, we estimated that there are 4.9 cases per 100,000 person-years in the age group 0-21 years. The highest survival was found in the 13- to 21-year age group (12.6%). Among patients 21 years old or younger, the following were associated with an increased chance of survival: increasing age, male gender, witnessed out-of-hospital cardiac arrest, ventricular-fibrillation, and a short emergency medical service response time. Among patients 21 years old or younger, there was an increase in survival from 6.2% in 1992-1998 to 14.0% in 2007-2012. Among 30-day survivors, 91% had a cerebral performance category score of 1 or 2 (good cerebral performance or moderate cerebral disability) at hospital discharge.Conclusions: In Sweden, among patients 21 years old or younger, five out-of-hospital cardiac arrests per 100,000 person-years occur and survival in this patient group has more than doubled during the past two decades. The majority of survivors have good or relatively good cerebral function.

- Three million people in Sweden are trained in cardiopulmonary resuscitation (CPR). Whether this training increases the frequency of bystander CPR or the survival rate among persons who have out-of-hospital cardiac arrests has been questioned.

- Aims: To describe out-of-hospital cardiac arrest (OHCA) in Sweden from a long-term perspective in terms of changes in outcome and circumstances at resuscitation.Methods and results: All cases of OHCA (n = 59 926) reported to the Swedish Cardiac Arrest Register from 1992 to 2011 were included. The number of cases reported (n/100 000 person-years) increased from 27 (1992) to 52 (2011). Crew-witnessed cases, cardiopulmonary resuscitation prior to the arrival of the emergency medical service (EMS), and EMS response time increased (P < 0.0001). There was a decrease in the delay from collapse to calling for the EMS in all patients and from collapse to defibrillation among patients found in ventricular fibrillation (P< 0.0001). The proportion of patients found in ventricular fibrillation decreased from 35 to 25% (P < 0.0001). Thirty-day survival increased from 4.8 (1992) to 10.7% (2011) (P < 0.0001), particularly among patients found in a shockable rhythm and patients with return of spontaneous circulation (ROSC) at hospital admission. Among patients hospitalized with ROSC in 2008–2011, 41% underwent therapeutic hypothermia and 28% underwent percutaneous coronary intervention. Among 30-day survivors in 2008–2011, 94% had a cerebral performance category score of 1 or 2 at discharge from hospital and the results were even better if patients were found in a shockable rhythm.Conclusion: From a long-term perspective, 30-day survival after OHCA in Sweden more than doubled. The increase in survival was most marked among patients found in a shockable rhythm and those hospitalized with ROSC. There were improvements in all four links in the chain of survival, which might explain the improved outcome.

Face Arm Speech Time Test use in the prehospital setting, better in the ambulance than in the emergency medical communication center

- BACKGROUND: Prehospital identification of acute stroke increases the possibility of early treatment and good outcome. To increase identification of stroke, the Face Arm Speech Time (FAST) test was introduced in the Emergency Medical Communication Center (EMCC). This substudy aims to evaluate the implementation of the FAST test in the EMCC and the ambulance service.METHODS: The study was conducted in the region of Stockholm, Sweden during 6 months. The study population consisted of all calls to the EMCC concerning patients presenting at least one FAST symptom or a history/finding making the EMCC or ambulance personnel to suspect stroke within 6 h. Positive FAST was compared to diagnosis at discharge. Positive predictive values (PPV) for a stroke diagnosis at discharge were calculated.RESULTS: In all, 900 patients with a median age of 71 years were enrolled, 667 (74%) by the EMCC and 233 (26%) by the ambulances. At discharge, 472 patients (52%) were diagnosed with stroke/transient ischemic attack (TIA), 337 identified by the EMCC (71%) and 135 (29%) by the ambulances. The PPV for a discharge diagnosis of stroke/TIA was 51% (CI 47-54%) in EMCC-enrolled and 58% (CI 52-64%) in ambulance-enrolled patients. With a positive FAST the PPV of a correct stroke/TIA diagnosis increased to 56% (CI 52-61%) and 73% (CI 66-80%) in EMCC- and ambulance-enrolled patients, respectively. Positive FAST from EMCC was also found in 44% of patients with a nonstroke diagnosis at discharge. A stroke/TIA diagnosis at discharge but negative FAST was found in 58 and 27 patients enrolled by the EMCC and ambulances, respectively.CONCLUSIONS: The PPV of FAST is higher when used on the scene by ambulance than by EMCC. FAST may be a useful prehospital tool to identify stroke/TIA but has limitations as the test can be negative in true strokes, can be positive in nonstrokes, and FAST symptoms may be present but not identified in the emergency call. For the prehospital care situation better identification tools are needed.
