Objective

To evaluate the degree to which registered nurses perceive their labor and delivery units to be adhering to Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) staffing guidelines.

Design

Prospective, cross-sectional study via an online survey of labor nurses recruited from hospitals in three states.

Setting/local problem

In late 2016 and early 2017, labor nurses in selected hospitals in California, Michigan, and New Jersey were contacted via e-mail invitation to participate in a study about nursing care during labor and birth. Nurse leaders in each hospital facilitated the invitations.

Participants

A total of 615 labor nurses from 67 hospitals.

Intervention/measurements

Descriptive statistics and linear regression models were used for data analysis.

Results

Most nurses reported that the AWHONN nurse staffing guidelines were frequently or always followed in all aspects of care surveyed. Hospitals with annual birth volumes of 500 to 999 range were significantly more likely than hospitals with 2,500 or more annual births to be perceived as compliant with AWHONN staffing guidelines.

Conclusion

When the AWHONN staffing guidelines were first published in 2010, there was concern among some nurse leaders that they would not be adopted into clinical practice, yet nurses in our sample overwhelmingly perceived their hospitals to be guideline compliant. There remains much more work to be done to determine nurse-sensitive outcomes for maternity care and to ensure that all women in labor in the United States are cared for by nurses who are not overburdened or distracted by being assigned more women than can be safely handled.

Purpose

The purpose of this study was to determine associations between missed nursing care and nurse staffing during labor and birth, and exclusive breast milk feeding at hospital discharge.

Study design and methods

Labor and birth nurses in three states were surveyed about missed nursing care and their maternity units' adherence to the AWHONN (2010) nurse staffing guidelines for care during labor and birth, using the Perinatal Misscare Survey. Nursing responses were aggregated to the hospital level and estimated associations between missed nursing care, nurse staffing, and hospitals' exclusive breast milk feeding rates were measured using The Joint Commission's Perinatal Care Measure (PC-05).

Results

Surveys from 512 labor nurses in 36 hospitals were included in the analysis. The mean exclusive breast milk feeding rate was 53% (range 13%-76%). Skin-to-skin care, breastfeeding within 1 hour of birth, and appropriate recovery care were on average occasionally missed (2.33 to 2.46 out of 4; 1 = rarely, 2 = occasionally, 3 = frequently, or 4 = always) and were associated with PC-05 [B(CI) -17.1(-29, -6.3), -17.9(-30.5, -6.2), and -15.4(-28.7, -2.1), respectively]. Adherence with overall staffing guidelines was associated with PC-05 [12.9(3.4, 24.3)]. Missed nursing care was an independent predictor of PC-05 [-14.6(-26.4, -2.7)] in a multilevel model adjusting for staffing guideline adherence, perceived quality, mean age of respondents, and nurse burnout.

Clinical implications

Exclusive breast milk feeding is a national quality indicator of inpatient maternity care. Nurses have substantial responsibility for direct support of infant feeding during the childbirth hospitalization. These results support exclusive breast milk feeding (PC-05) as a nurse-sensitive quality indicator.

In a previous study of hippocampal neurons in aging and AD [Lancet 344 (1994) 769], we demonstrated that the loss of neurons in the CA1 region was disease-specific and not related to aging. In the present study, we examined for loss of hippocampal neurons in preclinical AD, a period during which there are abundant amyloid deposits in the brain but no evidence of cognitive decline. We examined the postmortem brains of 33 subjects from the Baltimore Longitudinal Study of Aging and the Johns Hopkins Alzheimer's Disease Research Center. Using unbiased stereology, we estimated the total number of neurons in the granule cell layer, hilus, CA3-2, CA1, and subiculum of AD (n = 14) preclinical AD (n = 8), and age-matched control subjects (n = 11). The results from the present study confirm our previous finding of significant neuronal losses in the CA1 (48%), hilus (14%), and subiculum (24%) in AD [Lancet 344 (1994) 769]. However, we did not observe a significant loss of neurons in CA1 or any of the other subdivisions of the hippocampus in preclinical AD.

Missed nursing care is an important measure of nursing care quality that is sensitive to nurse staffing and is associated with patient outcomes in medical-surgical and pediatric inpatient settings. Missed nursing care during labor and birth has not been studied, yet childbirth represents the most common reason for hospitalization in the United States. The Missed Nursing Care (MISSCARE) Survey, a measure of medical-surgical nursing quality with substantial evidence for validity and reliability, was adapted to maternity nursing care using data from focus groups of labor nurses, physicians, and new mothers and an online survey of labor nurses. Content validity was evaluated via participant feedback, and exploratory factor analysis was performed to identify the factor structure of the instrument. The modified version, the Perinatal Missed Care Survey, appears to be a feasible and promising instrument with which to evaluate missed nursing care of women during labor and birth in hospitals.

AIM:: To evaluate the psychometric characteristics of the Perinatal Missed Care Survey and assess the prevalence of nurse-reported missed care during labor and birth. BACKGROUND:: Nursing care during labor and birth differs from other nursing care. Empirical evidence is scant regarding nursing quality and missed nursing care during labor and birth, which are important aspects of quality in maternity care. METHODS:: We conducted exploratory and confirmatory factor analysis on a previously developed perinatal missed nursing care instrument using data from 3,466 registered nurses. Measures included missed nursing care, reasons for missed nursing care, and demographic characteristics. All birth hospitals in each of 37 states were invited to distribute surveys electronically via email to their labor and delivery RN staff. The overall response rate from 277 hospitals that facilitated the survey was 35%. RESULTS:: Some missed care was reported for each of 25 missed care items. Labor support, intake and output, patient teaching, timely documentation, timely medication administration, and thorough review of prenatal records were missed at least occasionally by >50% respondents. Labor resources (83%), material resources (77%), and communication (60%) were reported reasons for missed nursing care. Exploratory factor analysis aligned with previous testing. Confirmatory factor analysis demonstrated good model fit. CONCLUSIONS:: The Perinatal Missed Care Survey demonstrates good validity and reliability as a measure of missed nursing care during labor and birth. Our findings suggest missed nursing care during labor and birth is prevalent and occurs in aspects of care that could contribute to patient harm when missed.

Background

Nursing care is essential to overall quality of healthcare experienced by patients and families-especially during childbearing. However, evidence regarding quality of nursing care during labor and birth is lacking, and established nurse-sensitive outcome indicators have limited applicability to maternity care. Nurse-sensitive outcomes need to be established for maternity care, and prior research suggests that the initiation of human milk feeding during childbirth hospitalization is a potentially nurse-sensitive outcome.

Objective

The aim of this study was to determine the relationship between nurse-reported staffing, missed nursing care during labor and birth, and exclusive breast milk feeding during childbirth hospitalization as a nurse-sensitive outcome.

Methods

2018 Joint Commission PC-05 Exclusive Breast Milk Feeding rates were linked to survey data from labor nurses who worked in a selected sample of hospitals with both PC-05 data and valid 2018 American Hospital Association Annual Survey data. Nurse-reported staffing was measured as the perceived compliance with Association of Women's Health, Obstetric and Neonatal Nurses staffing guidelines by the labor and delivery unit. Data from the nurse survey were aggregated to the hospital level. Bivariate linear regression was used to determine associations between nurse and hospital characteristics and exclusive breast milk feeding rates. Generalized structural equation modeling was used to model relationships between nurse-reported staffing, nurse-reported missed care, and exclusive breast milk feeding at the hospital level.

Results

The sample included 184 hospitals in 29 states and 2,691 labor nurses who worked day, night, or evening shifts. Bivariate analyses demonstrated a positive association between nurse-reported staffing and exclusive breast milk feeding and a negative association between missed nursing care and exclusive breast milk feeding. In structural equation models controlling for covariates, missed skin-to-skin mother-baby care and missed breastfeeding within 1 hour of birth mediated the relationship between nurse-reported staffing and exclusive breast milk feeding rates.

Discussion

This study provides evidence that hospitals' nurse-reported compliance with Association of Women's Health, Obstetric and Neonatal Nurses staffing guidelines predicts hospital-exclusive breast milk feeding rates and that the rates are a nurse-sensitive outcome.

Influenza B virus (FLUBV) poses a significant infectious threat, with frequent vaccine mismatch limiting its effectiveness. Our previous work investigated the safety and efficacy of modified live attenuated FLUBV vaccines with rearranged genomes (FluB-RAM and FluB-RANS) or a temperature-sensitive PB1 segment with a C-terminal HA tag (FluB-att). In this study, we compared the immune responses of female and male DBA/2J mice vaccinated with these vaccines, including versions containing a chimeric HA segment with an N-terminal IgA-inducing peptide (IGIP). Importantly, both recombinant viruses with and without IGIP remained genetically stable during egg passage. We found that introducing IGIP strengthened vaccine attenuation, particularly for FluB-RAM/IGIP. Prime-boost vaccination completely protected mice against lethal challenge with a homologous FLUBV strain. Notably, recombinant viruses induced robust neutralizing antibody responses (hemagglutination inhibition titers ≥40) alongside antibodies against NA and NP. Interestingly, female mice displayed a consistent trend of enhanced humoral and cross-reactive IgG and IgA responses against HA, NA, and NP compared to male counterparts, regardless of the vaccine used. However, the presence of IGIP generally led to lower anti-HA responses but higher anti-NA and anti-NP responses, particularly of the IgA isotype. These trends were further reflected in mucosal and serological responses two weeks after challenge, with clear distinctions based on sex, vaccine backbone, and IGIP inclusion. These findings hold significant promise for advancing the development of universal influenza vaccines.

Background

Hypothesis: neuromotor development correlates to body composition over the first year of life in prematurely born infants and can be influenced by enhancing motor activity.

Methods

Forty-six female and 53 male infants [27 ± 1.8 (sd) weeks] randomized to comparison or exercise group (caregiver provided 15-20 min daily of developmentally appropriate motor activities) completed the year-long study. Body composition [lean body and fat mass (LBM, FM)], growth/inflammation predictive biomarkers, and Alberta Infant Motor Scale (AIMS) were assessed.

Results

AIMS at 1 year correlated with LBM (r = 0.32, p < 0.001) in the whole cohort. However, there was no effect of the intervention. LBM increased by ~3685 g (p < 0.001)); insulin-like growth factor-1 (IGF-1) was correlated with LBM (r = 0.36, p = 0.002). IL-1RA (an inflammatory biomarker) decreased (-75%, p < 0.0125). LBM and bone mineral density were significantly lower and IGF-1 higher in the females at 1 year.

Conclusions

We found an association between neuromotor development and LBM suggesting that motor activity may influence LBM. Our particular intervention was ineffective. Whether activities provided largely by caregivers to enhance motor activity in prematurely born infants can affect the interrelated (1) balance of growth and inflammation mediators, (2) neuromotor development, (3) sexual dimorphism, and/or (4) body composition early in life remains unknown.

The hemagglutinin (HA) stem region is a major target of universal influenza vaccine efforts owing to the presence of highly conserved epitopes across multiple influenza A virus (IAV) strains and subtypes. To explore the potential impact of vaccine-induced immunity targeting the HA stem, we examined the fitness effects of viral escape from stem-binding broadly neutralizing antibodies (stem-bnAbs). Recombinant viruses containing each individual antibody escape substitution showed diminished replication compared to wild-type virus, indicating that stem-bnAb escape incurred fitness costs. A second-site mutation in the HA head domain (N129D; H1 numbering) reduced the fitness effects observed in primary cell cultures and likely enabled the selection of escape mutations. Functionally, this putative permissive mutation increased HA avidity for its receptor. These results suggest a mechanism of epistasis in IAV, wherein modulating the efficiency of attachment eases evolutionary constraints imposed by the requirement for membrane fusion. Taken together, the data indicate that viral escape from stem-bnAbs is costly but highlights the potential for epistatic interactions to enable evolution within the functionally constrained HA stem domain.

Live attenuated influenza virus (LAIV) vaccines elicit a combination of systemic and mucosal immunity by mimicking a natural infection. To further enhance protective mucosal responses, we incorporated the gene encoding the IgA-inducing protein (IGIP) into the LAIV genomes of the cold-adapted A/Leningrad/134/17/57 (H2N2) strain (caLen) and the experimental attenuated backbone A/turkey/Ohio/313053/04 (H3N2) (OH/04att). Incorporation of IGIP into the caLen background led to a virus that grew poorly in prototypical substrates. In contrast, IGIP in the OH/04att background (IGIP-H1att) virus grew to titers comparable to the isogenic backbone H1att (H1N1) without IGIP. IGIP-H1att- and H1caLen-vaccinated mice were protected against lethal challenge with a homologous virus. The IGIP-H1att vaccine generated robust serum HAI responses in naïve mice against the homologous virus, equal or better than those obtained with the H1caLen vaccine. Analyses of IgG and IgA responses using a protein microarray revealed qualitative differences in humoral and mucosal responses between vaccine groups. Overall, serum and bronchoalveolar lavage samples from the IGIP-H1att group showed trends towards increased stimulation of IgG and IgA responses compared to H1caLen samples. In summary, the introduction of genes encoding immunomodulatory functions into a candidate LAIV can serve as natural adjuvants to improve overall vaccine safety and efficacy.
