Study type
Interventional
Description of intervention(s) / exposure
Delivery of intravenous fluid therapy (Hartmans Fluid 3 L/24hrs per day) at home for women presenting to hospital emergency department (ED) with NVPHG who have a PUQE-24 score of greater than or equal to seven.

Women who have consented to receive intravenous fluid therapy at home will be provided with a fact/information sheet about NVPHG. Women will receive usual care in the ED going home with an intravenous cannula (IVC) in place to received further intravenous fluid therapy (IVT) in their home. IVT at home will be administered over three consecutive days by a home visiting community midwife or nurse.

This three day management of NVPHG at home will follow existing local health district (LHD) ambulatory care guidelines for women with NVPHG. Women will be asked to complete a Nausea and vomiting of pregnancy quality of life questionnaire (NVPQOL), the Productivity Cost Questionnaire (iPCQ) and the EQ-5D-3L survey at study entry and on completion of the three days of IVT. Participants will be asked to complete a 24hour Pregnancy unique quantifier of emesis (PUQE-24) daily over the three days of treatment then at study follow up phone call, along with a satisfaction survey. The community midwife or nurse will complete a Visual infusion Phlebitis score (VIP) score daily of the IVC site.

The PUQE-24 score will assist the home visiting midwife or nurse to assess effectiveness of IVT for each women and arrange appropriate medical review. Women will receive two to three litres of IVT each day, delivered at 500 ml to one litre per hour. The three day IVT management plan can be re commenced as many times as a women requires for the duration of her NVPHG.

Strategies to monitor adherence include: measurement of fluid left each day by visiting staff, interrogation of pump for running times and errors and daily assessment by visiting staff to assess if any other medications taken

Qualitative interviews will be conducted with 10 to 15 participants in the intervention and analysed thematically. Clinicians and managers (6 to 10) involved in the care of women with hyperemesis gravidarum will be sought to participate in qualitative interviews that will be analysed using content analysis to assess fidelity. Every woman sequentially will be invited to partake in the qualitative interviews. We expect to require about 6-10 women to reach saturation.

Treatment: Drugs
Comparator / control treatment
Retrospective/historical data analysis of ED presentations and admission for NVPHG over Jan 2021 and Dec 2021 within the LHD. The time to be covered retrospectively will match the time the study is to be undertaken. eg we expect it to take 12 months to recruit and hence the 12months retrospective data collection. If the study takes 18 months, we will retrospectively collect 18 months. ie it will be matched.

Safety/efficacy
Statistical methods / analysis
Comparison of the enrolled women with a 3:1 ratio comparison with historical controls (allowing for 80% power). By planning this analysis this will allow adequate power to assess for a reduced effect size to 30% (compared to the 50%reduction in the rate of admission or representations) between the control and the intervention group. Any differences in baseline data between the two groups will be adjusted for by using regression as appropriate. Data distribution assessed and appropriate test used to determine differences between groups for continuous and categorical data.

Summary
Brief summary
The aim of this project is to examine the implementation of a new model of care. This model of care will involve giving intravenous therapy (IVT) to women with nausea and vomiting of pregnancy in their home. We aim to assess if the number of times women present to emergency departments is reduced by receiving IVT at home and to explore the acceptability, sustainability and feasibility of this model of care with both women who participate in the project and with clinicians and managers involved in delivery of hospital in the home care, midwifery and obstetrics.
