Objective:
To develop a core outcome set for trials on the treatment of hyperemesis gravidarum (HG).
Design:
Identification of outcomes is followed by a modified Delphi survey combined with a consensus development meeting and a consultation round.
Setting:
An international web-based survey combined with a consensus development meeting.
Population:
Stakeholders including researchers; women with lived experience of HG and their families; obstetric health professionals; and other health professionals.
Methods:
We used systematic review, semi-structured patient interviews, closed group sessions and Steering Committee input to identify potential core outcomes. We conducted two web-based survey rounds, followed by a face-to-face consensus development meeting and a web-based consultation round.
Main Outcome Measures:
A core outcome set for research on HG.
Results:
Fifty-six potential outcomes were identified. The modified Delphi process was completed by 125 stakeholders, the consensus development meeting by 20 stakeholders and the consultation round by 96 stakeholders. Consensus was reached in ten domains on 24 outcomes: nausea; vomiting; inability to tolerate oral fluids or food; dehydration; weight difference; electrolyte imbalance; intravenous fluid treatment; use of medication for hyperemesis gravidarum; hospital treatment; treatment compliance; patient satisfaction; daily functioning; maternal physical or mental or emotional wellbeing; short- and long-term adverse effects of treatment; maternal death; pregnancy complications; considering or actually terminating a wanted pregnancy; preterm birth; small for gestational age; congenital anomalies; neonatal morbidity and offspring death).
Conclusions:
This core outcome set will help standardise outcome reporting in HG trials.
Tweetable Abstract:
A core outcome set for treatment of hyperemesis gravidarum in order to create high-quality evidence.

Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
