Objective:To investigate the quality of life of senior women with urinary incontinence and to explore its influencing factors.Methods:A convenient sampling method was used to select 152 senior women with urinary incontinence in Fuzhou Hot-Spring Street Community, Dongjie Street Community and Old-age Care Institutions from June 2017 to September 2017. The quality of life of elderly women with urinary incontinence were observed and the influencing factors were analyzed via International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF) and Incontinence Quality of Life Scale (I-QOL).Results:The quality of life of senior women with urinary incontinence was (98.7±12.2) points. The scores of the three dimensions including restrictive behavior, social activity limitation and psychological impact were 34.5±4.4 and 41.4±5.4 and 20.8 ± 3.5, respectively. There were 4 factors that influencing the quality of life of patients, namely, the severity of urinary incontinence, the type of urinary incontinence, diabetes and the frequency of leaking urine ( P<0.01). Conclusions:Urinary incontinence has a certain negative impact on the quality of life of patients, and its influencing factors are complex. Individualized care measures should be taken based on the influencing factors to improve the quality of life of patients.

Objective:To understand the epidemiological characteristics of imported COVID-19 cases in Guangzhou and provide scientific basis for the prevention and control of the disease.Methods:The data of imported COVID-19 in Guangzhou reported as of April 1, 2020 were collected from National Notifiable Disease Report System of China. The software Excel 2010 and SPSS 19.0 were applied for data cleaning and statistical analysis.Results:As of April 1, 2020, a total of 103 imported COVID-19 cases had been reported in Guangzhou, in which 92 were confirmed cases and 11 were asymptomatic infection cases. The number of the confirmed imported cases accounted for 11.4 % (92/806) in of the total in China at the same time. The male to female ratio of the cases was 1.58∶1 (63∶40). The median age of the cases was 31 years ( P 25- P 75:22-40 years), range of age was 11-63 years. The main occupational distributions of the cases were business services (41/103, 39.8 %) and students (36/103, 35.0 %). The imported cases whose destinations were 19 provinces and municipalities rather than Guangdong after entering the country accounted for 43.7 %. The main source countries of infections were the United Kingdom (27/103, 26.2 %), the Philippines (13/103, 12.6 %), the United States (13/103, 12.6 %) and Nigeria (7/103, 6.8 %). There were 34 inbound flights from which the imported COVID-19 cases were detected, in which 10 flights (10/34, 29.4 %) were found to carry more than 3 cases, with an average voyage time of (11.14±0.53) hours. A total of 29 imported cases(28.2 %) showed symptoms before entering the country, and 65 cases (63.1 %) had been isolated before the onset of the disease. The mean free activity time of the isolated cases after the onset was (6.76±0.79) days. The average number of the imported cases’ close contacts was 53. There were 13 clusters of COVID-19 caused by the imported cases, involving 36 cases (including 1 imported associated case). Conclusions:The sources of the imported COVID-19 cases in Guangzhou were widely distributed, and no cases had been found to be infected on the flights. In the early stage of the imported epidemic, there was high risk for the spread of the epidemic. Strengthened prevention and control of imported COVID-19 effectively reduced the of transmission risk of COVID-19 in communities.

PURPOSE: This study applied the Q method to identify and describe the various types of nurse perceptions that are crucially associated with their engagement in evidence-based nursing (EBN). METHODS: The study participants were nurses at a medical center and a regional teaching hospital. A series of Q sorts was performed by nurses to subjectively rank the Q statements. Q statements were constructed based on the literature related to EBN adoption by nurses and face-to-face interviews. RESULTS: A total of 60 participants were invited to rank 44 Q statements related to EBN. Factor analysis was conducted on the rankings of the Q statements. The following are the five prominent shared perspectives: (1) emphasized the obstacles to evidence searching and reading ability; (2) emphasized the organizational promotive strategies; (3) emphasized the available supportive resources; (4) emphasized the significance of EBN; and (5) emphasized the evidence-searching ability and external incentives. The five identified groups of perspectives can enhance hospital administrators to acknowledge the barriers and incentives associated with EBN practices. CONCLUSION: The exploration of clustering nurses' perceptions may facilitate the development of customized strategies to enable more appropriate training.
