简介:AbstractObjective:This survey was designed to understand the misconceptions about labor epidurals.Methods:This voluntary and anonymous online survey on wenjuan.com was conducted from September 1st, 2015 to January 1st, 2016 via mainly WeChat groups dedicated to perinatal healthcare providers in China. The questionnaire included items inquiring the knowledge and opinions about labor epidural analgesia related to maternal complications, baby safety, and effect on laboring. Incomplete surveys were excluded from the data analysis. The data was presented as percentages and a Chi-square test or Fisher’s exact test, as appreciate, was used to quantitatively compare the results.Results:A total of 1412 respondents completed surveys with 42.9% (606/1412) of them being anesthesiologists, 35.1% (495/1412) being obstetricians, 11.8% (167/1412) being midwives, 3.7% (52/1412) being labor and delivery nurses, and 6.5% (92/1412) being hospital administrators and unspecified. The study revealed a lack of knowledge in labor pain control. Although 82.4% (1164/1412) of respondents were familiar with labor epidural analgesia, 8.9% (126/1412) did not know how it works, and 1.1% (15/1412) never heard it in a multiple-choice question. The three main groups (anesthesiologists, obstetricians, and midwives/labor and delivery nurses) were chosen for comparisons. Opinions among these three groups concerning five questions in the three main concerns were evaluated using a statistical significance of P<0.05.Conclusion:The results in our survey indicated an urgent need of continuing medical education to multidisciplinary specialties to improve evidence-based medical practices as these misconceptions have existed for over 10 years in the medical professionals. Lack of public awareness fueled by misconceptions related to labor epidural analgesia may be associated with a lack of professional knowledge. Correct knowledge in professionals needs to be disseminated to the public in order to dispel possible misconceptions and rumors about labor epidural analgesia. This would not only enhance patient understanding of their care but also improve maternal, fetal, and neonatal outcomes.
简介:AbstractBackground:Zoonoses are public health threats that cause severe damage worldwide. Zoonoses constitute a key indicator of One Health (OH) and the OH approach is being applied for zoonosis control programmes of zoonotic diseases. In a very recent study, we developed an evaluation system for OH performance through the global OH index (GOHI). This study applied the GOHI to evaluate OH performance for zoonoses in sub-Saharan Africa.Methods:The framework for the OH index on zoonoses (OHIZ) was constructed including five indicators, 15 subindicators and 28 datasets. Publicly available data were referenced to generate the OHIZ database which included both qualitative and quantitative indicators for all sub-Sahara African countries (n = 48). The GOHI algorithm was used to estimate scores for OHIZ. Indicator weights were calculated by adopting the fuzzy analytical hierarchy process.Results:Overall, five indicators associated with weights were generated as follows: source of infection (23.70%), route of transmission (25.31%), targeted population (19.09%), capacity building (16.77%), and outcomes/case studies (15.13%). Following the indicators, a total of 37 sub-Sahara African countries aligned with OHIZ validation, while 11 territories were excluded for unfit or missing data. The OHIZ average score of sub-Saharan Africa was estimated at 53.67/100. The highest score was 71.99 from South Africa, while the lowest score was 40.51 from Benin. It is also worth mentioning that Sub-Sahara African countries had high performance in many subindicators associated with zoonoses, e.g., surveillance and response, vector and reservoir interventions, and natural protected areas, which suggests that this region had a certain capacity in control and prevention or responses to zoonotic events.Conclusions:This study reveals that it is possible to perform OH evaluation for zoonoses in sub-Saharan Africa by OHIZ. Findings from this study provide preliminary research information in advancing knowledge of the evidenced risks to strengthen strategies for effective control of zoonoses and to support the prevention of zoonotic events.
