Investigating Women's Experiences of Asthma Care in Pregnancy: A Qualitative Study

Are pregnant women with asthma receiving guideline-recommended antenatal asthma management? A survey of pregnant women receiving usual care in Australia

BACKGROUND

Asthma affects 12.7% of pregnant women in Australia. Key recommendations for asthma management during pregnancy include: 4-6 weekly review of lung function, medications, written asthma action plan, inhaler device technique, current asthma control and triggers; smoking cessation and vaccination advice. It is unknown if these key recommendations are provided to pregnant women with asthma in Australia.

AIM

To explore usual antenatal asthma management (usual care) in Australia and the inclusion of key recommendations.

METHOD

Pregnant women with asthma were invited to complete an online survey distributed in 2 antenatal clinics and via social media platforms from July 2017-Jan 2019.

RESULTS

The survey was completed by 142 pregnant women with asthma. 87(61%) were enrolled in an asthma management clinical trial and were therefore not receiving 'usual' care. Data presented is from 55(39%) women receiving usual care at survey completion. Of these women, 36% did not have their asthma reviewed during their pregnancy, 31% had a written asthma action plan, 11% had lung function assessed, 38% had an asthma medication review and 35% had their inhaler technique reviewed. 65% were not questioned about their asthma symptoms, 85% were not asked about asthma triggers, 96% were not given information about vaccinations and 95% did not receive smoking cessation information.

CONCLUSIONS

Overall, the key recommendations for antenatal asthma management were not always provided for this sample of pregnant women receiving usual care. Improved knowledge and implementation of these key recommendations by health professionals may alter this situation and improve maternal and infant outcomes.

Family planning, pregnancy and birth in women with lung conditions: a worldwide survey

Lung diseases can complicate pregnancy, but little is known about the experiences of pregnancy among women living with such diseases. This survey aimed to understand the experiences of women with a lung condition before and during pregnancy, in childbirth and post-partum.

The survey was translated into nine languages and hosted online between March and May 2018. This paper reports on 327 women who had asthma, cystic fibrosis (CF), lymphangioleiomyomatosis (LAM) and sarcoidosis as a sole or primary lung condition.

Women with CF and LAM were most likely to report that their condition influenced their decision to have children. Those with CF and LAM who did become pregnant reported greater satisfaction with their healthcare during pregnancy and gave more consideration to factors such as location and type of birth; they were also more concerned about the impact of the pregnancy on their health than women with other diseases. Women with sarcoidosis reported receiving conflicting advice as to both the impact of their condition on pregnancy and how becoming pregnant might impact their health. Women with asthma reported not always being able to access the information they needed from healthcare professionals.

The results suggest that healthcare providers should be having dialogues with affected women early on, from before conception, throughout the pregnancy and after giving birth, and training should be provided to healthcare staff to equip them with the information they need to do this.

This survey found that having a lung condition can play a significant role in women's decisions around family planning, pregnancy and birth. Women wanted more specialist support and better information before, during and after pregnancy.https://bit.ly/3CSpHt9

[Management of asthma during pregnancy]

Asthma is the most common chronic condition in pregnant women. The risks of complications associated with asthma for the mother, the foetus and the pregnancy are mainly due to uncontrolled asthma and the occurrence of exacerbations. These events are promoted by the patient's difficulty in complying with treatment or by prescription insufficiency for an unjustified fear of teratogenicity. The challenge of the management of asthma during pregnancy is to ensure optimal maternal asthma control in order to prevent foetal hypoxia and thus, reduce the risk of complications. Preventing the occurrence of asthma symptoms and exacerbations, ensuring optimal lung function and managing the risk factors of poor asthma outcomes and comorbidities are the principles necessary to achieve this goal. Because of the low or non-existent risks of the main treatments of asthma for the foetus and the mother, it is widely recommended that all therapies initiated before conception are continued, in particular inhaled corticosteroids, and to adjust the dosage to the minimum effective dose. During the preconception period and throughout pregnancy, coordination of the different healthcare professionals (general practitioner, respiratory specialist and gynecologist) is essential, with the mother-to-be playing a central role in the management of her asthma.

Medicines prescribed for asthma, discontinuation and perinatal outcomes, including breastfeeding: A population cohort analysis

OBJECTIVES

To explore associations between exposures to medicines prescribed for asthma and their discontinuation in pregnancy and preterm birth [<37 or <32 weeks], SGA [<10th and <3rd centiles], and breastfeeding at 6-8 weeks.

METHODS

Design. A population-based cohort study. Setting. The Secure Anonymised Information Linkage [SAIL] databank in Wales, linking maternal primary care data with infant outcomes. Population. 107,573, 105,331, and 38,725 infants born 2000-2010 with information on premature birth, SGA and breastfeeding respectively, after exclusions. Exposures. maternal prescriptions for asthma medicines or their discontinuation in pregnancy. Methods. Odds ratios for adverse pregnancy outcomes were calculated for the exposed versus the unexposed population, adjusted for smoking, parity, age and socio-economic status.

RESULTS

Prescriptions for asthma, whether continued or discontinued during pregnancy, were associated with birth at<32 weeks' gestation, SGA <10th centile, and no breastfeeding (aOR 1.33 [1.10-1.61], 1.10 [1.03-1.18], 0.93 [0.87-1.01]). Discontinuation of asthma medicines in pregnancy was associated with birth at<37 weeks' and <32 weeks' gestation (aOR 1.22 [1.06-1.41], 1.53 [1.11-2.10]). All medicines examined, except ICS and SABA prescribed alone, were associated with SGA <10th centile.

CONCLUSIONS

Prescription of asthma medicines before or during pregnancy was associated with higher prevalence of adverse perinatal outcomes, particularly if prescriptions were discontinued during pregnancy. Women discontinuing medicines during pregnancy could be identified from prescription records. The impact of targeting close monitoring and breastfeeding support warrants exploration.

Factors Associated with Nonadherence to Inhaled Corticosteroids for Asthma During Pregnancy

BACKGROUND

Nonadherence is common among pregnant women prescribed inhaled corticosteroids (ICS) for asthma and may have serious consequences for mother and baby. Factors associated with ICS nonadherence have not been determined in this population.

OBJECTIVES

To determine factors associated with {1} nonadherence to ICS in early-mid pregnancy (cross-sectional) and {2} persistent nonadherence to ICS during pregnancy (longitudinal).

METHODS

Data used come from 3 prospective studies (2004-2019) involving women with asthma recruited by 23 weeks' gestation (N = 1614). Demographics, asthma history, and current symptoms were assessed, and spirometry was performed at baseline and throughout pregnancy. Women self-reported current medication use and number of ICS doses missed in the past week. Nonadherence was defined as ≥20% of prescribed dosages missed in the past week (baseline) and on at least 2 occasions during follow-up (persistent). Factors associated with ICS nonadherence were examined using backward stepwise logistic regression.

RESULTS

Of 610 (38%) women prescribed ICS at baseline, 236 (39%) were classified as nonadherent. Of 612 (38%) women prescribed ICS during at least 2 follow-up visits, 149 (24%) were classified as persistent nonadherent. Factors associated with nonadherence at baseline were current or ex-smoking, non-Caucasian/non-Indigenous ethnicity, adult diagnosis of asthma, and lower lung function. Factors associated with persistent nonadherence to ICS were lower maternal age, higher parity, and no prescribed ICS at baseline.

CONCLUSION

Young multiparous non-Caucasian/non-Indigenous mothers are at increased risk of being nonadherent to ICS during pregnancy. Strategies to improve ICS nonadherence should address maternal smoking and target women who (re-)initiate ICS use in pregnancy.

mHealth resources for asthma and pregnancy care: Methodological issues and social media recruitment. A discussion paper

AIMS

A discussion of methodological issues and social media recruitment to a feasibility study to investigate mHealth resources for asthma and pregnancy care.

BACKGROUND

Pregnant women with asthma are reported to be poorly supported according to an international research. We sought to establish if a mHealth intervention might be feasible and acceptable to them.

DESIGN

A Phase I or modelling study.

METHODS

A project team designed an intervention to address UK national guidelines for the management of asthma during pregnancy, using other resources already accessible on the web. This was made available on a project website optimized for mobile phone usage. Links were Tweeted and advertised on Facebook, asking participants to access the project website, which included links to the resources and before- and after-use questionnaires to establish baseline symptom data and participant views of the resources.

RESULTS

Despite 55,700 Twitter impressions in a 76-day period over winter 2016-2017, this recruitment strategy garnered 402 engagements but only seven respondents for questionnaire 1 and zero respondents for questionnaire 2.

CONCLUSIONS

We could not recruit to this study despite believing that social media recruitment would be effective and we recommend that social media recruitment be used cautiously. Apparently, we did not sufficiently address the theoretical aspects of communications theory and were not clear enough about our key messages. Publication bias may exist about the non-publication of other failed telemedicine studies using social media; this goes largely unreported in some systematic reviews and may influence researchers' decision-making about social media recruitment.

Women's experiences of personalised support for asthma care during pregnancy: A systematic review of the literature

BACKGROUND

Asthma and pregnancy are both sources of anxiety for women. Although there has been a focus on physiological management of asthma and pregnancy, there has been little research on the impact that personalised support can have on asthma care during pregnancy. This systematic review and narrative synthesis of the literature set out to answer the question 'What are women's experiences of asthma care, its management and education, during pregnancy?'

METHODS

This systematic review was carried out using accepted methodology from the York Centre for Reviews and Dissemination. Electronic database searches were conducted using PsycInfo, CINAHL, MedLine, Google Scholar and the Cochrane Library, using the combination search terms: 'Asthma' AND 'Pregnancy' AND 'Care' AND ('Education OR Information OR Experience'). Hand searching of journals and searches for grey literature were also undertaken. Independent quality appraisal by the three authors took place using the criteria detailed by Kmet et al. (Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields, 2004).

RESULTS

All papers scoring in excess of 60% were deemed to be of adequate quality for inclusion, of which there were five: two qualitative designs and three quantitative designs. The designs were too methodologically heterogeneous to permit statistical meta-analysis so narrative review and synthesis was undertaken. Despite an embryonic evidence bases, it is reasonable to conclude that personalised care has beneficial outcomes for pregnant asthmatic women.

CONCLUSIONS

Larger randomised controlled trials investigating personalised care are required to build an evidence base which can establish the efficacy of such interventions.

Managing asthma in pregnancy

Asthma is a common comorbidity during pregnancy and its prevalence is increasing in the community. Exacerbations are a major clinical problem during pregnancy with up to 45% of women needing to seek medical help, resulting in poor outcomes for mothers and their babies, including low birth weight and preterm delivery. The goals of effective asthma management in pregnancy are to maintain the best possible asthma control and prevent exacerbations. This is achieved by aiming to prevent day- and night-time symptoms, and maintain lung function and normal activity. In addition, maintaining fetal oxygenation is an important consideration in pregnancy. Guidelines recommend providing asthma advice and review prior to conception, and managing asthma actively during pregnancy, with regular 4-weekly review, provision of a written action plan, use of preventer medications as indicated for other adults with asthma, and management of comorbid conditions such as rhinitis. Improvements have been made in recent years in emergency department management of asthma in pregnancy, and multidisciplinary approaches are being proposed to optimise both asthma outcomes and perinatal outcomes. One strategy that has demonstrated success in reducing exacerbations in pregnancy is treatment adjustment using a marker of eosinophilic lung inflammation, the exhaled nitric oxide fraction (F eNO). The use of an algorithm that adjusted inhaled corticosteroids (ICS) according to F eNO and added long-acting β-agonists when symptoms remained uncontrolled resulted in fewer exacerbations, more women on ICS but at lower mean doses, and improved infant respiratory health at 12 months of age. Further evidence is needed to determine whether this strategy can also improve perinatal outcomes and be successfully translated into clinical practice.

KEY POINTS

Asthma is the most common chronic disease to affect pregnant women.Exacerbations occur in up to 45% of pregnant women with asthma.Asthma should be managed during pregnancy as for other adults.Treatment adjustment using a marker of airway inflammation reduces the exacerbation rate in pregnancy.
