RESUMO
A post-hoc exploratory analysis of the PIONEER 9 and 10 trials evaluated the effect of baseline age (<65 and ≥65 years) on the efficacy and safety of oral semaglutide in Japanese patients with type 2 diabetes. In PIONEER 9 and 10, patients were randomized to once-daily oral semaglutide (3, 7 or 14 mg) or a comparator (placebo or once-daily subcutaneous liraglutide 0.9 mg [PIONEER 9]; once-weekly subcutaneous dulaglutide 0.75 mg [PIONEER 10]) for 52 weeks, with 5 weeks' follow-up. In total, 701 patients were included (PIONEER 9: N = 243; PIONEER 10: N = 458). Glycaemic efficacy of oral semaglutide was similar in Japanese patients aged <65 years compared with those ≥65 years, and there did not appear to be a clear pattern between age subgroup and body weight changes. Across treatment arms, adverse events generally occurred in greater proportions of patients aged ≥65 versus <65 years. There was generally a higher rate of premature trial product discontinuation because of adverse events in the older age group. These results indicate that oral semaglutide is efficacious in Japanese patients irrespective of age.

BACKGROUND: Self-instruction with a DVD and a simple personal manikin is an effective alternative to traditional basic life support (BLS) courses. Objective To evaluate the effect of distributing DVD training kits to untrained laypersons. BLS skills were compared according to 2005 guidelines for resuscitation after 3.5 months with those obtained in untrained laypersons who completed the same course with instructor facilitation. METHODS: BLS skills of 55 untrained laypersons were assessed using the Laerdal ResusciAnne and PC Skill Reporting System in a 3 min test and a total score (12-48 points) was calculated. The participants received a DVD training kit without instructions. The test was repeated after 3.5 months. Data were compared with data from a previous published study where participants completed the same course in groups with instructor facilitation. RESULTS: There was no statistically significant difference in the total score after 3.5 months. The 'DVD-self-instructor' group obtained 33 (29-37) points and the 'DVD-with instructor' group obtained 34 (32-37) points, p=0.16. The 'DVD-with instructor' group performed significantly better in checking responsiveness and had a significantly shorter 'total hands-off time' (s) (85 (76-94) vs 96 (82-120), p=0.002) and delay until first compression or ventilation group (29 s (17-40) vs 33 s (22-48), p=0.04). CONCLUSIONS: Since no significant difference in total BLS score was found after 3.5 months between untrained laypersons who either completed a DVD-based BLS course in groups with instructor facilitation or received the same DVD training kit without instruction, the latter seems more efficient.

BACKGROUND: In Copenhagen, a volunteer-based Automated External Defibrillator (AED) network provides a unique opportunity to assess AED use. We aimed to determine the proportion of Out-of-Hospital Cardiac Arrest (OHCA) where an AED was applied before arrival of the ambulance, and the proportion of OHCA-cases where an accessible AED was located within 100 m. In addition, we assessed 30-day survival. METHODS: Using data from the Mobile Emergency Care Unit and the Danish Cardiac Arrest Registry, we identified 521 patients with OHCA between October 1, 2011 and September 31, 2013 in Copenhagen, Denmark. RESULTS: An AED was applied in 20 cases (3.8%, 95% CI [2.4 to 5.9]). Irrespective of AED accessibility, an AED was located within 100 m of a cardiac arrest in 23.4% (n=102, 95% CI [19.5 to 27.7]) of all OHCAs. However, at the time of OHCA, an AED was located within 100 m and accessible in only 15.1% (n=66, 95% CI [11.9 to 18.9]) of all cases. The 30-day survival for OHCA with an initial shockable rhythm was 64% for patients where an AED was applied prior to ambulance arrival and 47% for patients where an AED was not applied. CONCLUSIONS: We found that 3.8% of all OHCAs had an AED applied prior to ambulance arrival, but 15.1% of all OHCAs occurred within 100 m of an accessible AED. This indicates the potential of utilising AED networks by improving strategies for AED accessibility and referring bystanders of OHCA to existing AEDs.

BACKGROUND: On the Danish island of Bornholm an intervention was carried out during 2008-2010 aiming at increasing out-of-hospital cardiac arrest (OHCA) survival. The intervention included mass media focus on resuscitation and widespread educational activities. The aim of this study was to compare the bystander BLS rate and survival after OHCA on Bornholm in a 3-year follow-up period after the intervention took place. METHODS: Data on OHCA on Bornholm were collected from September 28th, 2010 to September 27th, 2013 and compared to data from the intervention period, September 28th, 2008 to September 27th, 2010. RESULTS: The bystander BLS rate for non-EMS witnessed OHCAs with presumed cardiac aetiology was significantly higher in the follow-up period (70% [95% CI 61-77] vs. 47% [95% CI 37-57], p=0.001). AEDs were deployed in 22 (18%) cases in the follow-up period and a shock was provided in 13 cases. There was no significant change in all-rhythm 30-day survival for non-EMS witnessed OHCAs with presumed cardiac aetiology (6.7% [95% CI 3-13] in the follow-up period; vs. 4.6% [95% CI 1-12], p=0.76). CONCLUSION: In a 3-year follow-up period after an intervention engaging laypersons in resuscitation through mass education in BLS combined with a media focus on resuscitation, we observed a persistent significant increase in the bystander BLS rate for all OHCAs with presumed cardiac aetiology. There was no significant difference in 30-day survival.

BACKGROUND: Valuable information can be retrieved from automated external defibrillators (AEDs) used in victims of out-of-hospital cardiac arrest (OHCA). We describe our experience with systematic downloading of data from deployed AEDs. The primary aim was to compare the proportion of shockable rhythm from AEDs used by laypersons with the corresponding proportion recorded by the Emergency Medical Services (EMS) on arrival. METHODS: In a 20-month study, we collected data on OHCAs in the Capital Region of Denmark where an AED was deployed prior to arrival of EMS. The AEDs were brought to the emergency medical dispatch centre for data downloading and rhythm analysis. Patient data were retrieved from the medical records from the admitting hospital, whereas data on EMS rhythm analyses were obtained from the Danish Cardiac Arrest Register between 2001 and 2010. RESULTS: A total of 121 AEDs were deployed, of which 91 cases were OHCAs with presumed cardiac origin. The prevalence of initial shockable rhythm was 55.0% (95% CI [44.7-64.8%]). This was significantly greater than the proportion recorded by the EMS (27.6%, 95% CI [27.0-28.3%], p<0.0001). Shockable arrests were significantly more likely to be witnessed (92% vs. 34%, p<0.0001) and the bystander CPR rate was higher (98% vs. 85%, p=0.04). More patients with initial shockable rhythm achieved return of spontaneous circulation upon hospital arrival (88% vs. 7%, p<0.0001) and had higher 30-day survival rate (72% vs. 5%, p<0.0001). CONCLUSION: AEDs used by laypersons revealed a higher proportion of shockable rhythms compared to the EMS rhythm analyses.

BACKGROUND: Survival after out-of-hospital cardiac arrest (OHCA) is improved when bystanders provide Basic Life Support (BLS). However, bystander BLS does not occur frequently. The aim of this study was to assess the effects on attitudes regarding different aspects of resuscitation of a one-year targeted media campaign and widespread education in a rural Danish community. Specifically, we investigated if the proportion willing to provide BLS and deploy an automated external defibrillator (AED) increased. METHODS: BLS and AED courses were offered and the local television station had broadcasts about resuscitation in this study community. A telephone enquiry assessed the attitudes towards different aspects of resuscitation among randomly selected citizens before (2008) and after the project (2009). RESULTS: For responses from 2008 (n = 824) to 2009 (n = 815), there was a significant increase in the proportions who had participated in a BLS course within the past 5 years, from 34% to 49% (p = 0.0001), the number willing to use an AED on a stranger (p < 0.0001), confident at providing chest compressions (p = 0.03), and confident at providing mouth-to-mouth ventilations (MMV) (p = 0.048). There was no significant change in the proportions willing to provide chest compressions (p = 0.15), MMV (p = 0.23) or confident at recognizing a cardiac arrest (p = 0.09). The most frequently reported reason for not being willing to provide chest compressions, MMV and use an AED was insecurity about how to perform the task. CONCLUSION: A targeted media campaign and widespread education can significantly increase the willingness to use an AED, and the confidence in providing chest compressions and MMV. The willingness to provide chest compressions and MMV may be less influenced by a targeted campaign.

BACKGROUND: Automated External Defibrillators (AEDs) are known to increase survival after out-of-hospital cardiac arrest (OHCA). The aim of this study was to examine the use and benefit of public-access defibrillation (PAD) in a nation-wide network. We primarily sought to assess survival at 1 month but information about the circumstances of each OHCA is provided as well. METHODS: In this 28-month study, we assessed the use of 807 AEDs in Denmark. When an AED was deployed information about the circumstances of OHCA, the bystander, the AED and the victim's condition was obtained. RESULTS: An AED was connected to an OHCA victim prior to the arrival of Emergency Medical Services (EMS) in 48 instances. Ten percent of bystanders were off-duty healthcare professionals. Shockable arrests (N=31, 70%) were significantly more likely to be witnessed (94% vs. 54%) to occur at sports facilities (74% vs. 31%), in relation to exercise (42% vs. 0%), and with improved 30-day survival (69% vs. 15%, p=0.001). Among those presenting with a shockable rhythm, 20 (65%) had Return of Spontaneous Circulation upon arrival of EMS and 8 (26%) were conscious, which emphasizes the diagnostic value of ECG downloads from AEDs. Survival could be determined in 42 of 44 patients with OHCA of cardiac origin, and was 52% (n=22, 95% CI [38-67]) and the Cerebral Performance Category was 1 (Good Cerebral Performance) in all survivors. CONCLUSION: With a 30-day neurologically intact survival of 69% for patients with shockable rhythms, this study provides further evidence of the lifesaving potential of PAD.

BACKGROUND: Ambulance personnel play an essential role in the 'Chain of Survival'. The prognosis after out-of-hospital cardiac arrest was dismal on a rural Danish island and in this study we assessed the cardiopulmonary resuscitation performance of ambulance personnel on that island. METHODS: The Basic Life Support (BLS) and Automated External Defibrillator (AED) skills of the ambulance personnel were tested in a simulated cardiac arrest. Points were given according to a scoring sheet. One sample t test was used to analyze the deviation from optimal care according to the 2005 guidelines. After each assessment, individual feedback was given. RESULTS: On 3 consecutive days, we assessed the individual EMS teams responding to OHCA on the island. Overall, 70% of the maximal points were achieved. The hands-off ratio was 40%. Correct compression/ventilation ratio (30:2) was used by 80%. A mean compression depth of 40-50 mm was achieved by 55% and the mean compression depth was 42 mm (SD 7 mm). The mean compression rate was 123 per min (SD 15/min). The mean tidal volume was 746 ml (SD 221 ml). Only the mean tidal volume deviated significantly from the recommended (p = 0.01). During the rhythm analysis, 65% did not perform any visual or verbal safety check. CONCLUSION: The EMS providers achieved 70% of the maximal points. Tidal volumes were larger than recommended when mask ventilation was applied. Chest compression depth was optimally performed by 55% of the staff. Defibrillation safety checks were not performed in 65% of EMS providers.

BACKGROUND: Video-based self-instruction (VSI) with a 24-min DVD and a personal resuscitation manikin solves some of the barriers associated with traditional basic life support (BLS) courses. No accurate assessment of the actual improvement in skills after attending a VSI course has been determined, and in this study we assess the skill improvement in laypersons undergoing VSI. METHODS: The BLS skills of 68 untrained laypersons (high school students, their teachers and persons excluded from mainstream society) were assessed using the Laerdal ResusciAnne and PC Skill Reporting System 2.0 in a 3 min test. A total score (12-48 points) was calculated and 12 different variables were recorded. The participants attended a 24-min VSI course (MiniAnne, Laerdal) and took home the DVD and manikin for optional subsequent self-training. We repeated the test 3 1/2-4 months later. RESULTS: There was a significant increase in the total score (p<0.0001) from 26.5 to 34 points. The participants performed significantly better in checking responsiveness, opening the airway, checking for respiration and using the correct compression/ventilation ratio (all p-values<0.001). The compression depth improved from 38 mm to 49.5 mm and the total number of compressions increased from 67 to 141. The ventilation volume and the total number of ventilations increased, and total "hands-off" time decreased from 120.5 s to 85 s. CONCLUSIONS: Untrained laypersons attending a 24 min DVD-based BLS course have a significantly improved BLS performance after 3 1/2-4 months compared to pre-test skill performance. Especially the total number of compressions improved and the hands-off time decreased.

INTRODUCTION: In 2005, new international evidence-based guidelines for cardiopulmonary resuscitation (CPR) were published by the International Liaison Committee on Resuscitation (ILCOR). The aim of these new guidelines is to improve the quality of care and, thereby, the outcome from cardiac arrest. This necessitates that the guidelines are known and implemented in clinical practice. The purpose of this investigation is to elucidate the extent of implementation of Guidelines 2005 (G2005) among doctors on Cardiac Arrest Teams (CAT) one year after the publication. In addition, the date of implementation is examined among medical emergency services and major providers of basic life support (BLS) courses. MATERIAL AND METHODS: A telephone enquiry about CPR among CAT doctors on-duty. Ambulance services and BLS-course providers are contacted by e-mail. RESULTS: Approximately 70% of the doctors were able to answer simple and essential topics on CPR, e.g. compression/ventilation ratio and the number of shocks in a sequence in accordance with G2005. The ambulance service, Falck A/S, implemented G2005 during 2007, while the other ambulance services implemented G2005 within six months after publication. The majority of BLS-course providers implemented the guidelines one year after their publication. CONCLUSION: One year after the publication of G2005, there is limited knowledge of the guidelines among doctors on duty. The study does not give any explanation for the lack of implementation. The barriers to implementation should be clarified, and future guidelines should be accompanied by an active strategy for implementation.
