The mediating effect of psychological empowerment on the relationship between work environment and clinical decision-making among midwives: a multicentre cross-sectional study.

BACKGROUND: Clinical decision-making is considered an essential behaviour in clinical practice. However, no research has been done to examine the associations among midwives' clinical decision-making, work environment and psychological empowerment. Thus, this study aimed to determine the influence of work environment on midwives' clinical decision-making and confirm the mediating role of psychological empowerment. METHOD: This study was designed as a multicentre cross-sectional study, and included 602 registered midwives from 25 public hospitals in China. A sociodemographic questionnaire, Work Environment Scale, Psychological Empowerment Scale and Clinical decision-making Scale were applied. A structural equation model was conducted to estimate the hypothesis model of the clinical decision-making among midwives and explore the potential mediating mechanism of midwives' clinical decision-making. This model was employed maximum likelihood estimation method and bootstrapping to examine the statistical significance. RESULTS: The mean score of clinical decision-making among midwives was 143.03 ± 14.22, at an intermediate level. The data of this hypothesis model fitted well, and the results showed that work environment positively affected psychological empowerment, which in turn positively affected clinical decision-making; psychological empowerment partly mediated the relationship between work environment and clinical decision-making among midwives. CONCLUSIONS: Midwives' clinical decision-making could be promoted directly or indirectly by providing a healthy work environment and improving psychological empowerment. It is essential for hospital managers to pay attention to the assessment of the midwives' work environment and actively improve it, such as establishing a supportive, fair and just workplace, and maintaining effective communication with midwives. Furthermore, managers can also promote midwives' clinical decision-making behaviour by enhancing their psychological empowerment via enhancing job autonomy.

Effects of coping on nurses' mental health during the COVID-19 pandemic: Mediating role of social support and psychological resilience.

BACKGROUND: Fighting against the COVID-19 pandemic, front-line nurses were under unprecedented psychological pressure. Therefore, it is necessary to promptly evaluate the psychological status of nurses during the COVID-19 epidemic period. AIM: To investigate nurses' mental health during the COVID-19 pandemic, and to test the mediating role of social support and psychological resilience between coping and mental health. DESIGN: This was a descriptive, cross-sectional survey which used a structural equation model. METHOD: In total, 711 registered nurses were included. All participants were invited to complete a socio-demographic questionnaire, the general health questionnaire, the trait coping style questionnaire, the perceived social support scale and the Conner-Davidson Resilience scale. RESULTS: In total, 50.1% nurses had high risk of mental health. Positive coping positively affected social support and psychological resilience, while it negatively affected mental health. Negative coping negatively affected social support and psychological resilience, while it positively affected mental health. Social support positively affected psychological resilience, while it negatively affected mental health. In addition, social support mediated coping and psychological resilience, and coping and mental health. Moreover, psychological resilience negatively affected mental health, and it mediated coping and mental health.

Effect of midwife-led care on birth outcomes of primiparas.

BACKGROUND: The high caesarean section rate is a prominent public health problem in China. AIM: This study aimed to determine the effects of midwife-led care during labour on birth outcomes for healthy primiparas. DESIGN: Randomized controlled trial. SETTING: The Obstetrics Department of Fujian Provincial Maternity and Child Health Hospital. METHODS: A total of 666 primiparas in labour were randomly divided into an intervention and control group (333 in each group). The intervention group received a midwife-led model of care during labour. RESULTS: Data from 648 cases (331 intervention group and 317 control group) were analysed. The intervention group was less likely to experience caesarean section, postpartum haemorrhage, opiate analgesia, vaginal examinations, neonatal asphyxia, and neonatal hospitalization and was more likely to experience shorter length of labour and vaginal birth than the control group (all, P < 0.05). No differences were found in the number of artificial rupture of membranes and oxytocin use (P > 0.05). CONCLUSIONS: Midwife-led care can reduce the caesarean section rate, promote normal birth, improve birth outcomes, and promote maternal and child health.

[A correlation analysis between the rate of vertical transmission of HBV and HBsAg-positive father to infant and the rate of neonatal cord blood HBV-DNA].

OBJECTIVE: To study the influence of HBV-DNA with different load levels of HBsAg-positive among fathers on the rate of neonatal cord blood HBV-DNA. METHODS: Using HBsAg and HBV-DNA as screening indicators for pregnant women and their husbands from an obstetric clinic. 161 pregnant women whose HBsAg and HBV-DNA were negative, but HBsAg was positive among their husbands and their newborns, were selected. Blood samples from those pregnant women, their husbands and their newborns were collected to detect the related indicators. Using ELISA to detect hepatitis B virus markers (HBVM), and FQ-PCR to detect the levels of HBV-DNA load. According to neonatal cord blood HBV-DNA detection guideline, newborns with cord blood HBV-DNA positive were selected as cases, others as controls. RESULTS: (1) Result of the study showed that there was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive rates in newborns (trend χ(2) = 64.117, P = 0.000). The rate of vertical transmission of HBV from HBsAg-positive father to infant in the paternal serum HBV-DNA ≥ 1.0 × 10(7) copies/ml group was significantly higher than HBV-DNA < 1.0 × 10(7) copies/ml group (χ(2) = 71.539, P = 0.000). (2) There was a positive rank correlation between semen positive HBeAg and vertical transmission of HBV from HBsAg-positive father to infant (χ(2) = 6.892, P = 0.009). CONCLUSION: There was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive in newborns. Paternal serum HBV-DNA ≥ 1.0 × 10(7) copies/ml and with HBeAg positive status were risk factors of vertical transmission of HBV from HBsAg-positive father to infant.

[Risk factors for paternal vertical transmission of hepatitis B virus.].

OBJECTIVE: To explore the risk factors of and the influence of different hepatitis B virus (HBV) DNA load on paternal vertical transmission of HBV. METHODS: Totally, 161 HBsAg negative women, whose husband was HBsAg positive, attended the antenatal clinics of the Provincial Maternity and Child Health Hospital of Fujian from September 2007 to December 2008 and their newborns were selected, and the epidemiologic information, the duration of being a HBV carrier, the first class HBV family history of the fathers, HBV markers, HBV DNA load, HBsAb of the gravidas, the outcomes of the newborns were all collected. Cord blood was sampled after delivery for HBV DNA quantification and those with HBV DNA load >/= 1.0 x 10(3) copy/ml were chosen as the case group and those < 1.0 x 10(3) copy/ml as control. RESULTS: (1) Among the 161 newborns, 36 HBV DNA positive cord blood samples were detected, giving a rate of 22.4% (36/161) for paternal vertical transmission of HBV. The HBV DNA positive rate in cord blood was 32.0% (23/72) in HBeAg-positive fathers and 14.6% (13/89) in HBeAg-negative fathers. (2) Univariate analysis showed that HBeAg-positive, HBV DNA positive, first class family history of HBV and the duration of being a HBV carrier of the fathers were risk factors of paternal HBV vertical transmission [chi(2) = 6.892, 29.916, 29.499 and 23.821, OR = 2.7, 5.2, 8.3 and 1.4 (P < 0.01)]. (3) Multivariate analysis found that paternal serum HBV DNA positive and the first class family history of HBV of the father side were risk factors of paternal vertical transmission of HBV (OR = 11.1, 95%CI: 4.6 - 27.1; OR = 17.1, 95%CI: 3.5 - 82.6). (4) According to the different serum HBV DNA load of the HBsAg-positive father, 7 groups were divided. A dose dependent effect was found that the HBV DNA positive rate of the cord blood increased with the rising of HBV DNA load. No HBV DNA positive cord blood was detected when paternal HBV DNA load was < 1.0 x 10(4) copy/ml, while 100% of the cord blood were positive when paternal HBV DNA load >/= 1.0 x 10(8) copy/ml. (5) The average birth weight of the newborns in the two groups was the same (3.3 +/- 0.4) kg. And the delivery mode, gestational age at delivery, height and Apgar score of the newborns at 1 minute, neonatal pathological jaundice and other complications had no significant difference between the two groups (P > 0.05). No relationship was found between the neonatal outcomes and the paternal HBV vertical transmission (P > 0.05). CONCLUSIONS: HBV DNA load in the serum of HBsAg-positive father, and the paternal first class family history of HBV are risk factors of paternal HBV vertical transmission. When the serum HBV DNA load in HBsAg-positive father is >/= 1.0 x 10(7) copy/ml, the possibility of paternal vertical transmission of HBV would increase.
