Maternal awareness, acceptability and willingness towards respiratory syncytial virus (RSV) vaccination during pregnancy in Ireland.

BACKGROUND: Respiratory syncytial virus (RSV) is the world's leading cause of viral acute lower respiratory infections (ALRI) in infants. WHO has identified maternal RSV vaccination a priority and candidate vaccines are in development; however, vaccine hesitancy remains an impediment to successful implementation of maternal immunization. This study, the largest antenatal survey conducted to-date, aimed to examine maternal RSV awareness, likely acceptance of RSV vaccination in pregnancy, and attitudes to maternal vaccination. METHODS: Pregnant women of all gestations attending antenatal clinic of a university maternity hospital in Ireland were invited to participate. An information leaflet provided, consent obtained, and survey administered examining RSV awareness, willingness to avail of antenatal RSV vaccination, factors influencing acceptability and preferred sources of assistance. Research Ethics Committee (REC) approval obtained, and general data protection regulation (GDPR) guidelines followed. RESULTS: 528 women completed the survey. A large proportion (75.6%) had never heard of RSV, yet 48.5% would still avail of a vaccine, 45.8% were undecided and only 5.3% would not. The main factor making vaccination acceptable to women (76.4%) was that it protects their infant from illness (p < .001, CV 0.336 for association with acceptance) and general practitioner (GP) was the preferred guidance source in decision-making (57.7%). CONCLUSIONS: Despite low levels of maternal awareness of RSV, pregnant women in Ireland are open to availing of antenatal vaccination. Maternal immunization strategies need to focus on infant's protection from RSV-associated ALRI along with vaccine safety, and build on an interdisciplinary collaboration of maternal, neonatal, primary care and public health services.

Estimates for quality of life loss due to Respiratory Syncytial Virus.

BACKGROUND: In children aged <5 years in whom severe respiratory syncytial virus (RSV) episodes predominantly occur, there are currently no appropriate standardised instruments to estimate quality of life years (QALY) loss. OBJECTIVES: We estimated the age-specific QALY loss due to RSV by developing a regression model which predicts the QALY loss without the use of standardised instruments. METHODS: We conducted a surveillance study which targeted confirmed RSV episodes in children aged <5 years (confirmed cases) and their household members who experienced symptoms of RSV during the same time (suspected cases). All participants were asked to complete questions regarding their health during the infection, with the suspected cases additionally providing health-related quality of life (HR-QoL) loss estimates by completing EQ-5D-3L-Y or EQ-5D-3L instruments. We used the responses from the suspected cases to calibrate a regression model which estimates the HR-QoL and QALY loss due to infection. FINDINGS: For confirmed RSV cases in children under 5 years of age who sought health care, our model predicted a QALY loss per RSV episode of 3.823 × 10-3 (95% CI 0.492-12.766 × 10-3 ), compared with 3.024 × 10-3 (95% CI 0.329-10.098 × 10-3 ) for under fives who did not seek health care. Quality of life years loss per episode was less for older children and adults, estimated as 1.950 × 10-3 (0.185-9.578 × 10-3 ) and 1.543 × 10-3 (0.136-6.406 × 10-3 ) for those who seek or do not seek health care, respectively. CONCLUSION: Evaluations of potential RSV vaccination programmes should consider their impact across the whole population, not just young child children.

Impact of Respiratory Syncytial Virus-Confirmed Hospitalizations on Caregivers of US Preterm Infants.

This study assessed the impact of respiratory syncytial virus-confirmed hospitalizations (RSVH) on caregivers of high-risk preterm infants. Caregivers for infants born at 29 to 35 weeks' gestational age and hospitalized for confirmed RSV disease responded to measures of self-rated and perceived infant stress (1-7; 7 = very stressful), perceived infant health (0-100; 100 = best imaginable health), and productivity impairment. Data were collected at hospital discharge through 1 month post-discharge. Caregiver responses indicated high stress levels, poor health, and productivity loss were reported at discharge; however, steady improvements were seen through 1 month post-discharge: caregiver-rated stress (from 6 to 2), infant stress (5 to 1), caregiver-perceived infant health (64 to 84), and productivity loss (mothers: 91% to 31%; fathers: 81% to 18%). Qualitative results indicated emotional impact, family routine disruption, financial concerns, and medical concerns persisted at 1 month post-discharge. This study found the caregiver burden of RSVH persists at least 1 month beyond discharge.

Experiences of Alaskan parents with children hospitalized for respiratory syncytial virus treatment.

The purpose of this study was to describe the experiences of Alaskan parents with children hospitalized for the treatment of the respiratory syncytial virus (RSV). Six parents participated in a qualitative descriptive study composed of individual interviews. Using content analysis, three major themes emerged: "RSV is scary," "Lots of stress; little rest" and "At what point does it become a Bingo? He's going to the hospital." Findings provided further insight into the educational needs of the participants. Advanced practice registered nurses can translate insights provided by the participants into crucial knowledge needed for the care of families at heightened risk and currently experiencing RSV.

Health-related quality of life in preschool children in five health conditions.

OBJECTIVE: To test the responsiveness of the Infant/Toddler Quality of Life Questionnaire (ITQOL) to five health conditions. In addition, to evaluate the impact of the child's age and gender on the ITQOL domain scores. METHODS: Observational study of 494 Dutch preschool-aged children with five clinical conditions and 410 healthy preschool children randomly sampled from the general population. The clinical conditions included neurofibromatosis type 1, wheezing illness, bronchiolitis, functional abdominal complaints, and burns. Health-related quality of life (HRQoL) was assessed by a mailed parent-completed ITQOL. Mean ITQOL scale scores for all conditions were compared with scores obtained from the reference sample. The effect of patient's age and gender on ITQOL scores was assessed using multi-variable regression analysis. RESULTS: In all health conditions, substantially lower scores were found for several ITQOL scales. The conditions had a variable effect on the type of ITQOL domains and a different magnitude of effect. Scores for 'physical functioning', 'bodily pain', and 'general health perceptions' showed the greatest range. Parental impact scales were equally affected by all conditions. In addition to disease type, the child's age and gender had an impact on HRQoL. CONCLUSIONS: The five health conditions (each with a distinct clinical profile) affected the ITQOL scales differently. These results indicate that the ITQOL is sensitive to specific characteristics and symptom expression of the childhood health conditions investigated. This insight into the sensitivity of the ITQOL to health conditions with different symptom expression may help in the interpretation of HRQoL results in future applications.

The impact of severe respiratory syncytial virus on the child, caregiver, and family during hospitalization and recovery.

OBJECTIVE: To quantify the magnitude of child, caregiver, and family distress associated with hospitalization for severe respiratory syncytial virus (RSV) and the posthospitalization recovery period. DESIGN: A prospective study of 46 RSV-hospitalized infants and children < or =30 months of age with a history of prematurity (gestational age of < or =35 weeks) and 45 age-matched control subjects was performed. RSV group data were gathered during hospitalization and on days 4, 14, 21, and 60 after discharge; control group data were collected at the end of the RSV season and 60 days thereafter. MAIN OUTCOME MEASURES: RSV severity; caregiver's rating of the child's health (100-point rating) and functional status (Functional Status IIR); caregiver health, stress (7-point rating), and anxiety (Spielberger State Anxiety Inventory); and family health and functioning (Family Adaptability and Cohesion Evaluation Scale II) were recorded. RESULTS: The mean age of the sample was 10.2 months; 51% of the subjects were male. The average duration of hospital stay for the RSV group was 5.8 +/- 8 days. Most patients received supplemental oxygen (76%) and were monitored for apnea (60%). The mean age of the caregivers (93% mothers) was 29 years. During hospitalization, the RSV-infected patients' health and functional status were significantly poorer than those of control subjects. Caregivers of RSV-infected children reported more stress, greater anxiety, poorer health, and poorer family health and functioning. As long as 60 days after discharge, caregivers of RSV-infected children reported the children's health as significantly poorer and were personally more anxious, compared with control subjects. CONCLUSIONS: RSV-related hospitalization creates significant distress for infants and children, caregivers, and families, with some effects extending as long as 60 days after discharge.
