Effects of professional support on nausea, vomiting, and quality of life during early pregnancy

The effect of educational intervention on the quality of life of women suffering from pregnancy-related nausea and vomiting: a systematic review

OBJECTIVE

The present study aimed to determine the influence of educational interventions on improving the quality of life (QOL) of women suffering from pregnancy-related nausea and vomiting (NVP) as a systematic review.

METHODS

The current systematic review followed the standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist guideline. The English electronic databases were used to identify relevant studies published 2000 until 14 August 2023. The search strategies employed were based on Mesh browser keywords and free-text words. The study risk of bias was evaluated using the Cochrane Collaboration's tool for assessing the risk of bias tools and publication bias was evaluated using a funnel plot and Begg and Egger tests. The heterogeneity of the studies was evaluated using I2 and tau-squared tests. Data were analyzed using the RevMan 5 software. Results of the random-effects meta-analysis were presented using the standard mean difference, along with a 95% confidence interval (CI).

RESULTS

Out of the seven randomized clinical/control trial (RCT) studies with a total of 946 subjects included in the review, five studies reported a significant result, indicating that the interventions had a statistically significant effect on the QOL of women suffering NVP and in two studies did not have a significant result. A subgroup analysis was done based on the type of quality-of-life measurements. The pooled standardized mean difference (SMD) of four articles (Nausea and Vomiting Pregnancy Quality of Life, NVPQOL) with a total of 335 subjects was -2.91, and CI of -4.72 to -1.11, p value = .002, I2 = 97.2%. The pooled SMD of three articles (SF36) with a total of 611 subjects was -0.05, and CI of -0.23 to -0.12, p value = .550, I2 = 10%.

CONCLUSIONS

The overall results of the analysis indicated that educational intervention had a small positive impact on the QOL of women experiencing NVP. However, to draw a better conclusion, it is recommended to conduct further studies with larger sample sizes and longer follow-up periods.

Enhancing maternal wellbeing: A qualitative exploration of women's experiences of tailored education and holistic support while experiencing Hyperemesis Gravidarum

PROBLEM

Hyperemesis Gravidarum (HG), poses significant physical, psychological, emotional, and financial challenges for affected women and their families. Despite its prevalence and impact, tailored education and holistic support interventions are lacking.

BACKGROUND

Nausea and vomiting in pregnancy affect 69 % of pregnancies, HG impacts around 1.1 %, though it is likely underreported. It is a leading cause of early pregnancy hospitalisation. Prior research highlights the benefits of professional support, including individualised health education and telephone calls. However, understanding the experiences of women with HG receiving personalised care remains a gap.

METHODS

A qualitative, explorative study employing reflexive thematic analysis was used to understand the experience of women with HG who were enrolled and recruited from a newly established treatment program. In-depth semi structured interviews (n = 9) were conducted with participants throughout 2022 and 2023 at the conclusion of their HG experience.

FINDINGS

Four main themes were identified - The impact of HG; Lack of understanding and recognition of HG; Impact of HG Program; and Need for improved resources and education.

DISCUSSION

Women's experience with HG highlights the significant physiological and psychosocial impact and the need for increased clinician knowledge and support. Having dedicated HG clinicians can positively impact symptom reduction, mental health, and health-system navigation.

CONCLUSION

HG profoundly affects women. Tailored education and holistic support by dedicated clinicians is crucial. There is a need for improved recognition, support, and access to care, advocating for expanded services and increased clinician knowledge and response skills.

The IRIS clinic: A Protocol for a mixed-methods study evaluating the management of Hyperemesis Gravidarum

Background

Hyperemesis Gravidarum (HG) is a severe form of nausea and vomiting in pregnancy that affects 0.3-3% of women and has profound nutritional, physical and psychological consequences. Research is lacking regarding the most effective management of the condition. In response to patient feedback, a multidisciplinary HG day-case service (IRIS Clinic) was launched in 2020 at The National Maternity Hospital, Ireland. The clinic provides routine, day-case care in a comfortable space with pre-booked appointments. The MDT involves midwives, dietitians, perinatal mental health, obstetrics and pharmacy, and the nature of the clinic enables peer-to-peer support. As this clinic is the first of its kind in Ireland, we aim to assess its effectiveness and feasibility, and suggest recommendations for improvement.

Methods

This is a sequential, mixed-methods study that commenced in August 2021. The prospective arm of the study is ongoing and involves enrolling women (n = 50) who are attending the IRIS clinic. Data are collected on first admission (pre-intervention) and approximately 8 weeks' later (post-intervention) relating to symptoms of HG, well-being, food tolerances, quality of life and nutritional intake. Qualitative, semi-structured interviews will be conducted to evaluate women's experiences of attending the clinic. The retrospective arm of the study will be a chart review (n = 200) of women diagnosed with HG to describe assessments, treatments and pregnancy and birth outcomes.

Conclusion

The IRIS clinic has the potential to improve pregnancy outcomes and nutritional status among women with HG. If found to be effective and feasible, the model for this clinic could be replicated elsewhere.

The NVP QOL Questionnaire: Psychometric properties of the self-report measure of health-related quality of life for nausea and vomiting during pregnancy

Aim

The Nausea and Vomiting of Pregnancy Quality of Life (NVP QOL) Questionnaire is a self-report measure of health-related QOL for nausea and vomiting during pregnancy. This study determines the best fitting factor structure for the NVP QOL Questionnaire and explores its measurement invariance in terms of observation time and parity.

Methods

A test-retest study of pregnant women was conducted at Gestational Weeks (GWs) 10-13 (T1: N = 381) and 1 week later (T2: n = 128) at one hospital and five clinics with the NVP QOL and the Pregnancy-Unique Quantification of Emesis and Nausea (PUQE). Exploratory and confirmatory factor analyses were performed to compare different factor structure models and evaluate measurement invariance of the best fitting model between two time points and between primiparas and multiparas. Concurrent validity of the NVP QOL was clarified by correlations with the PUQE, Sheehan Disability Scale, and other scales.

Results

The one-factor model had the best fit. This factor structure model was acceptable up to the factor invariance level for two time points and up to the factor mean level for primiparas versus multiparas. Correlations between NVP QOL, PUQE, and Sheehan Disability Scale scores were strong. Women with higher NVP QOL scores were more likely to lose weight, have lower daily fluid intake, have reduced fluid and food intake since pregnancy began, and receive outpatient or inpatient treatment.

Conclusion

The one-factor structure and measurement invariance of the NVP QOL at different times and parities were demonstrated, suggesting that the NVP QOL can be used to evaluate primiparas and multiparas in a longitudinal study.

Identifying Patterns of Symptom Distress in Pregnant Women: A Pilot Study

During pregnancy, a woman's enlarged uterus and the developing fetus lead to symptom distress; in turn, physical and psychological aspects of symptom distress are often associated with adverse prenatal and birth outcomes. This study aimed to identify the trends in the trajectory of these symptoms. This longitudinal study recruited 95 pregnant women, with a mean age of 32 years, from the prenatal wards of two teaching hospitals in northern Taiwan. Symptom distress was measured by a 22-item scale related to pregnancy-induced symptoms. The follow-up measurements began during the first trimester and were taken every two to four weeks until childbirth. More than half of the pregnant women experienced symptom distress manifested in a pattern depicted to be "Decreased then Increased" (56.8%). Other noticeable patterns were "Continuously Increased" (28.4%), "Increased then Decreased" (10.5%) and "Continuously Decreased" (4.2%), respectively. It is worth noting that most pregnant women recorded a transit and increase in their symptom distress, revealed by their total scores, at the second trimester (mean 22.02 weeks) of pregnancy. The participants' major pregnancy-related distress symptoms were physical and included fatigue, frequent urination, lower back pain, and difficulty sleeping. The mean scores for individual symptoms ranged from 2.32 to 3.61 and were below the "moderately distressful" level. This study provides evidence that could be used to predict women's pregnancy-related symptom distress and help healthcare providers implement timely interventions to improve prenatal care.

The effect of hyperemesis gravidarum on prenatal adaptation and quality of life: a prospective case-control study

AIM

The aim of the study was to determine the adaptation status of hyperemesis gravidarum in pregnancy and its effects on quality of life.

METHODS

The study was carried out between January and December 2018 in at the gynecology services and obstetrics clinics of a public hospital in Turkey. The study included pregnant women as the case group (n = 150) in their first and second trimesters diagnosed with hyperemesis gravidarum and pregnant women with healthy pregnancy (n = 150). In order to obtain information pertinent to the participants, a "Personal Information Form" was used, the "Quality of Life (SF36) Form" was used to determine quality of life, and to determine adaption to pregnancy, the "Prenatal Self-Evaluation Scale" was applied. Only the "Acceptance of Pregnancy" and "Acceptance of the Role of the Motherhood" subdimensions were included in the study since the pregnant women in their first and second trimesters participated.

RESULTS

Acceptance of pregnancy (p = .000) and acceptance of the role of motherhood (p = .018) were found to be significantly lower in the pregnant women with hyperemesis gravidarum in comparison to the healthy pregnant women. The quality of life levels of the pregnant women with hyperemesis gravidarum were found to be lower than those in the healthy pregnant women (p < .001). According to the correlation analysis that was performed, it was determined that the decrease in the quality of life coincided with the decrease in acceptance of the role of motherhood (p < .001).

CONCLUSIONS

Hyperemesis gravidarum adversely affects quality of life. Additionally, hyperemesis gravidarum and low quality of life negatively affect acceptance of pregnancy and the role of motherhood.

Transformation of quality of life in prenatal women with nausea and vomiting

PROBLEM

Nausea and vomiting not only cause physical discomfort in pregnant women but also impact their quality of life.

BACKGROUND

Few longitudinal studies have been conducted to investigate QOL of women over the course of pregnancy.

AIM

To examine the transformation of health-related QOL and related factors among pregnant women with NV during three trimesters.

METHODS

A longitudinal research design with convenience sampling was used. A structural questionnaire was used to repeatedly measure the data of 101 pregnant women with NV during the first, second, and third trimesters. A generalized estimating equation (GEE) was used to analyze the collecting data.

FINDINGS

The results showed significant differences in symptom distress, prenatal stress, and health-related QOL among the three trimesters in pregnant women with NV (p<0.001). The scores of symptom distress, prenatal stress, and health-related QOL in the first trimester were significantly higher than those in the second and third trimesters (p<0.001). The GEE indicated that the trimester of pregnancy, severity of NV, symptom distress, and prenatal stress were key factors for the transformation of health-related QOL of women with NV during pregnancy.

DISCUSSION

The findings of this study are seminal in terms of understanding the relationships between symptom distress, prenatal stress and health-related QOL in pregnant women with NV over the course of a pregnancy.

CONCLUSION

This study can serve as a reference for designing interventions (i.e., professional support) for women in different pregnancy stages to improve their health-related QOL during pregnancy.

Evaluation of nausea and vomiting in pregnancy using the Pregnancy-Unique Quantification of Emesis and Nausea scale in Korea

Objective

Severity of nausea and vomiting of pregnancy (NVP) is associated with adverse pregnancy outcomes and poorer quality of life (QOL). The aim of this study was to evaluate the severity of NVP and maternal well-being status using the Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) scale in a Korean population.

Methods

A total of 527 pregnant women who were receiving prenatal care at 4 hospitals were asked to participate in the study between January 2015 and June 2015. The severity of NVP was evaluated by the PUQE scale and maternal well-being status was evaluated using the visual analogue scale (VAS). Statistical analyses were performed to determine the risk factors associated with NVP and the associations between the severity of NVP and QOL.

Results

Among the 472 eligible pregnant women, 381 (80.7%) were suffering from NVP during pregnancy. No significant differences (P>0.05) were observed in any of the variables between the 2 study groups, with the exception of smoking, alcohol consumption, and history of NVP. NVP history was found to be the most powerful risk factor (adjusted odds ratio, 11.6; 95% confidence interval, 4.7-28.7). The correlation coefficient (r) between the VAS scores of maternal well-being status and PUQE severity was -0.25 (r²=0.062; P<0.001).

Conclusion

In this study, an explicit decline in maternal well-being status was observed according to severity of NVP. The PUQE scale may be of help to clinicians, healthcare providers, and researchers because of its simplicity and usefulness as a tool for NVP evaluation.

Treatment options for hyperemesis gravidarum

Hyperemesis gravidarum (HG) is a severe and prolonged form of nausea and/or vomiting during pregnancy. HG affects 0.3-2% of pregnancies and is defined by dehydration, ketonuria, and more than 5% body weight loss. Initial pharmacologic treatment for HG includes a combination of doxylamine and pyridoxine. Additional interventions include ondansetron or dopamine antagonists such as metoclopramide or promethazine. The options are limited for women who are not adequately treated with these medications. We suggest that mirtazapine is a useful drug in this context and its efficacy has been described in case studies. Mirtazapine acts on noradrenergic, serotonergic, histaminergic, and muscarinic receptors to produce antidepressant, anxiolytic, antiemetic, sedative, and appetite-stimulating effects. Mirtazapine is not associated with an independent increased risk of birth defects. Further investigation of mirtazapine as a treatment for HG holds promise to expand treatment options for women suffering from HG.

The effect of a telephone-based cognitive behavioral therapy on quality of life: a randomized controlled trial

Health-related quality of life (HRQoL) has emerged as a major public health concern in perinatal care. The purpose of this study was to examine the effect of telephone-based cognitive behavioral therapy (T-CBT) on HRQoL among Chinese mothers at risk of postnatal depression at 6 weeks and 6 months postpartum. A multi-center randomized controlled trial was conducted at the postnatal units of three regional hospitals. Three hundred and ninety-seven women at risk of postnatal depression were recruited and were randomly assigned to the T-CBT (n = 197) or usual care (n = 200). Assessment was conducted at baseline, 6 weeks and 6 months postpartum for HRQoL. Women in the T-CBT experienced greater improvement in the physical component of HRQoL from baseline to 6 weeks and 6 months postpartum than the usual care group. At 6 months postpartum, the T-CBT group also experienced better HRQoL in the mental component of HRQoL than the usual care group. The T-CBT appears to be feasible and effective in improving HRQoL in women at risk of postnatal depression in the primary care practice.

Associations between Nausea, Vomiting, Fatigue and Health-Related Quality of Life of Women in Early Pregnancy: The Generation R Study

The objective of this study was to evaluate the independent associations between nausea, vomiting, fatigue and health-related quality of life of women in early pregnancy in the Generation R study, which is a prospective mother and child cohort. Analyses were based on 5079 women in early pregnancy in the Rotterdam area, the Netherlands. The information on nausea, vomiting and fatigue in the previous three months was measured in the questionnaire at enrollment, as well as potential confounders (i.e., maternal/gestational age, ethnic background, educational level, parity, marital status, body mass index, tobacco and alcohol use, chronic/infectious conditions, uro-genital conditions/symptoms, sleep quality, headache, anxiety, and depression). Health-related quality of life was assessed by the 12-item Short Form Health Survey and physical and mental component summary scores were calculated. Multivariate regression models were performed to evaluate the independent associations of the presence of nausea, vomiting and fatigue with health-related quality of life, adjusting for potential confounders. 33.6% of women experienced daily presence of nausea, 9.6% for vomiting and 44.4% for fatigue. Comparing with women who never reported nausea, vomiting and fatigue, women with daily presence of at least one of these symptoms had significantly lower scores of physical component summary and mental component summary, after adjusting for potential confounders. Our study shows how common nausea, vomiting and fatigue are among women in early pregnancy and how much each of these symptoms negatively impact on health-related quality of life. We call for awareness of this issue from health care professionals, pregnant women and their families.

Interventions for nausea and vomiting in early pregnancy

BACKGROUND

Nausea, retching and vomiting are very commonly experienced by women in early pregnancy. There are considerable physical, social and psychological effects on women who experience these symptoms. This is an update of a review of interventions for nausea and vomiting in early pregnancy last published in 2014.

OBJECTIVES

To assess the effectiveness and safety of all interventions for nausea, vomiting and retching in early pregnancy, up to 20 weeks' gestation.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, the Cochrane Complementary Medicine Field's Trials Register (19 January 2015) and reference lists of retrieved studies.

SELECTION CRITERIA

All randomised controlled trials of any intervention for nausea, vomiting and retching in early pregnancy. We excluded trials of interventions for hyperemesis gravidarum, which are covered by another Cochrane review. We also excluded quasi-randomised trials and trials using a cross-over design.

DATA COLLECTION AND ANALYSIS

Four review authors, in pairs, reviewed the eligibility of trials and independently evaluated the risk of bias and extracted the data for included trials.

MAIN RESULTS

Forty-one trials involving 5449 women, met the inclusion criteria. These trials covered many interventions, including acupressure, acustimulation, acupuncture, ginger, chamomile, lemon oil, mint oil, vitamin B6 and several antiemetic drugs. There were no included studies of dietary and other lifestyle interventions. Evidence regarding the effectiveness of P6 acupressure, auricular (ear) acupressure and acustimulation of the P6 point was limited. Acupuncture (P6 or traditional) showed no significant benefit to women in pregnancy. The use of ginger products may be helpful to women, but the evidence of effectiveness was limited and not consistent, though three recent studies support ginger over placebo. There was only limited evidence from trials to support the use of pharmacological agents including vitamin B6, Doxylamine-pyridoxoine and other anti-emetic drugs to relieve mild or moderate nausea and vomiting. There was little information on maternal and fetal adverse outcomes and on psychological, social or economic outcomes.We were unable to pool findings from studies for most outcomes due to heterogeneity in study participants, interventions, comparison groups, and outcomes measured or reported. The methodological quality of the included studies was mixed. Risk of bias was low related to performance bias, detection bias and attrition bias for most studies. Selection bias risk was unclear for many studies and almost half of the studies did not fully or clearly report all pre-specified outcomes.

AUTHORS' CONCLUSIONS

Given the high prevalence of nausea and vomiting in early pregnancy, women and health professionals need clear guidance about effective and safe interventions, based on systematically reviewed evidence. There is a lack of high-quality evidence to support any particular intervention. This is not the same as saying that the interventions studied are ineffective, but that there is insufficient strong evidence for any one intervention. The difficulties in interpreting and pooling the results of the studies included in this review highlight the need for specific, consistent and clearly justified outcomes and approaches to measurement in research studies.
