RESUMO
ObjectiveTo investigate the prevenance rate and related factors of anxiety among the public before and after outbreak of COVID-19， and to provide scientific guidance for public health emergency response in psychological intervention field. MethodsBy using the convenient sampling method， residents in Chinese mainland participated in predesigned questionnaire survey from February 7th to February 14th， 2020， meantime， all the selected individuals were assessed using Self-rating Anxiety Scale （SAS）. The anxiety status was also retrospectively evaluated before January 20th， prior to the outbreak. Thereafter， a before-and-after comparison was conducted on the anxiety status， and the related influencing factors were discussed. ResultsA total of 1 222 valid questionnaires were collected， with a valid rate of 93.8%. After the outbreak， the number of people with anxiety symptoms increased from 90 （7.4%） to 172 （14.1%）， with statistical difference （P<0.01）. The SAS score increased from （40.65±10.43） to （36.32±8.46）， with statistical difference （P<0.01）. For overall sample， the independent risk factors of anxiety aggravation included serious disruptions of daily life （P<0.01）， older age （P<0.01）， female （P<0.01）， poor education background （P=0.005）， occupied in medical staff （P=0.031） and lack of medical education （P=0.039）. For medical staff， the independent risk factors of anxiety aggravation included sense of being-alienated （P<0.01）， older age （P<0.01）， female （P=0.002） and serious disruptions of daily life （P=0.044）. ConclusionThe prevalence rate of anxiety is increased after the outbreak of COVID-19， especially among the general public with serious disruptions of daily life， older age， females， poor education background， and the lack of medical education， and among medical staff with sense of being-alienated， older age， females， and serious disruptions of daily life.
RESUMO
Objective To systemically analyze the effect of continuous aspiration of subglottic suction (CASS) on the incidence of ventilator-associated pneumonia (VAP) and other outcomes in mechanical ventilated patients.Methods PubMed,Cochrane Library,Ovid,EBSCOhost,ScienceDirect,Google scholar,CNKI,CBM and Wanfang Database were searched for the RCTs about the effect of CASS on the outcomes of mechanical ventilated patients from July 1994 to July 2014,and the relevant journals were also hand-searched.Data were extracted independently by two reviewers.Meta analysis was conducted using RevMan 5.1 software.Results Data extracted from 7 RCTs with a total of 1 566 patients were analyzed.The risks of developing clinically diagnosed VAP were significantly lower among the patients receiving CASS [RR =0.54,95％ CI(0.43,0.65),P＜0.01],episodes of VAP occurred later in patients receiving CASS [MD=3.52,95％CI(1.98,5.06),P＜0.01],the duration of mechanical ventilation [MD=-2.03,95％CI(-2.23,-1.73),P＜0.01]and length of ICU stay were reduced [MD=-2.99,95％CI(-3.75,-2.23),P＜0.01],while no significant differences were detected between the two groups regarding the mortality rate [RR=0.98,95％CI (0.80,1.20),P＞0.05].Conclusion This study proved that the CASS did have effect in reducing the incidence of VAP,but it is limited by lack of enough RCTs with high quality.Large sample of high quality RCTs is necessary to examine the wider applicability of CASS.
RESUMO
Objective To describe the burden of caregivers of children with asthma,and to provide reference for the development of family care support program.Methods Qualitative research was used to carry out semi-structured interviews with 13 caregivers of children with asthma in the pediatric outpatient of the First Affiliated Hospital of Guangzhou Medical University.The data collected were analyzed with Colaizzi 7-step analysis method.Results The carcgiver burden was classified into 4 themes,including time and energy exhaustion,heavy economic burden,insufficient knowledge of care and negative emotions.Conclusions The burden of caregivers of children with asthma has a relatively great impact on the daily work and life,even the physical and mental health.Care workers should be concerned about the status of caregiver burden and provide targeted interventions,which could help caregiver adapt to their roles,maintain and promote the health of children patients and their families.
RESUMO
Objective To evaluate the effectiveness of clinical pathways for pediatric asthma.Methods The literatures on the application of clinical pathways for pediatric asthma were collected in the databases such as PubMed,Cochrane Library,Ovid,ScienceDirect,EBSCOhost,CNKI,Wanfang and CBM while a manual search was added.The search was performed from 1980 to 2014.Two reviewers independently screened references,extracted data and assessed the risk of bias.Data was pooled and analyzed by using Revman 5.2 version.Results Eleven studies involving 2 207 participants from nearly 1 048 relevant studies met the inclusion criteria.1 174 participants were in the clinical pathway group while the other 1 033 participants were in the control group.Meta-analysis result showed that patients with asthma in a clinical pathway had a shorter length of stay,less medical cost,reduced rate of emergency room visits,and improved health education.However,clinical pathway did not appear to reduce readmission.Conclusions Clinical pathway can significandy reduce the length of hospital stay,cost,rate of emergency room visits and improve health education.
