BACKGROUND: Automated external defibrillators (AEDs) enable laypeople to provide early defibrillations to patients undergoing cardiac arrest, but scant information is available on the general public’s ability to use AEDs. This study assessed the ability of laypeople to operate AEDs, the effect of a 15-minute training, and whether skills differed by age. METHODS: From May 1 to December 31, 2018, a prospective simulation study was conducted with 94 laypeople aged 18-65 years (32 aged 18-24 years, 34 aged 25-54 years, and 28 aged 55-65 years) with no prior AED training. The participants’ AED skills were assessed individually pre-training, post-training, and at a three-month follow-up using a simulated cardiac arrest scenario. The critical actions and time intervals were evaluated during the AED operating process. RESULTS: Only 14 (14.9%) participants (eight aged 18-24 years, four aged 25-54 years, and two aged 55-65 years) successfully delivered defibrillations before training. AED operation errors were more likely to occur among the participants aged 55-65 years than among other age groups. After training, the proportion of successful defibrillations increased significantly (18-24 years old: 25.0% vs. 71.9%, P<0.01; 25-54 years old: 11.8% vs. 70.6%, P<0.01; 55-65 years old: 7.1% vs. 67.9%, P<0.01). After three months, 26.1% of the participants aged 55-65 years successfully delivered defibrillations, which was significantly lower than that of participants aged 18-24 years (54.8%) and 25-54 years (64.3%) (P=0.02). There were no differences in time measures among three age groups in each test. CONCLUSIONS: The majority of untrained laypeople cannot effectively operate AEDs. More frequent training and refresher courses are crucial to improve AED skills.

Objective To explore the influence of psychological first aid training on cognitive appraisal of sudden events in medical students.Methods A medical university undergraduate students were selected and divided into the training group(n=42) and the control group(n=53).The former was treated with 20 hours short-term targeted psychological first aid,and the latter was treated as blank control.The SAM and LMSQ were adopted to measure students' cognitive appraisal before and after the training.Results After the training,the training group gained significant differences (P＜ 0.05) in threat (11.95 ±3.17) vs (10.45±2.48)(t=2.426,P=0.020),challenge (12.64t2.84) vs (14.40±1.95)(t=-3.304,P=0.002),controllable-by-self (13.05±3.15) vs (14.93±2.00) (t=-3.240,P=0.002),controllable-by-others (12.40±3.10) vs (14.52±2.52) (t=-3.553,P=0.001),stressfulness (13.26±2.69) vs (12.00±1.96) (t=2.592,P=0.013) of SAM,and Physical threat ((23.88±7.59) vs (19.76±4.82),t=3.057,P=0.004) of LMSQ compared with before training.Other factors had no significant difference(P＞0.05).Compared with two groups,the training group gained significant increase(P＜0.05) on the score differences for SAM factors (challenge (t=-2.466,P=0.016),controllable-by-self (t=-2.557,P=0.012),controllable-by-others (t=-2.800,P=0.006)) than the control group,and significant reduction (P＜0.05) in physical threat (t=-2.308,P=0.023) of LMSQ.Conclusion Short-term targeted psychological first aid training has certain effects on changing cognitive appraisal about sudden events for medical students.

Objective To explore the value of urinary albumin/creatinine ratio (ACR) in coronary heart disease(CHD) compli-cating thyroid dysfunction and its correlation with the various detection indicators of thyroid function.Methods The results of uri-nary ACR and thyroid function detection in 863 patients with CHD in our hospital from November 2015 to August 2016 were col-lected.According to the standards of American National Kidney Foundation (NKF) and Food and Drug Administration(FDA) ,863 CHD patients were divided into the group A (ACR≤10.0 mg/g · Cr) ,B(10.0 mg/g · Cr< ACR≤30.0 mg/g · Cr) ,C (30.0 mg/g · Cr300 mg/g · Cr).According to the reference values of thyroid functional indica-tors ,these patients were divided into the thyroid function normal and abnormal groups.Results The ACR level was negatively cor-related with the FT3 level in 863 CHD patients(r= -0.297 ,P<0.05) ,and was positively related with the FT 4 level(r=0.172 , P<0.05).The abnormal rate of thyroid function had significantly statistical difference among four groups (χ2 =33.533 ,P<0.05). The abnormal rate of thyroid function had significantly statistical difference between the patients with ACR >10.0 mg/g · Cr and the patients with ACR ≤ 10.0 mg/g · Cr ,the difference was statistically significant (P< 0.05) ,its risk degree was 2.083. Conclusion ACR is likely to be a risk factor for CHD patients complicated with thyroid dysfunction.It is necessary to monitor the thyroid function when ACR level >10.0 mg/g · Cr in CHD patients.
