Views on outpatient paracentesis and GnRH antagonists for ovarian hyperstimulation syndrome: a qualitative study of patients and healthcare professionals.

Background: Ovarian hyperstimulation syndrome is a significant complication of fertility treatment, where the ovaries become enlarged if they are overstimulated, resulting in fluid leakage. Ovarian hyperstimulation syndrome can be classified as mild, moderate or severe. Symptoms vary dependent on severity but can include abdominal swelling, pain, nausea and vomiting, and shortness of breath. Treatment typically consists of monitoring initially, with active intervention if the condition progresses to a severe state, requiring hospitalisation. This study explored the acceptability and feasibility of outpatient paracentesis, and of gonadotropin-releasing hormone antagonists, as early interventions for ovarian hyperstimulation syndrome. Methods: We conducted qualitative semi-structured interviews with healthcare professionals from fertility clinics ( Results: Both healthcare professionals and patients were supportive of the proposed trials. Key findings included that healthcare professionals recommended clarity on patient eligibility, hospitalisation criteria and consent procedures. Patients expressed a desire to be given more detailed information about potential trials and had mixed opinions on self-monitoring. There were some concerns from both parties about treatment risks, particularly the paracentesis. Healthcare professionals noted a shift to more preventative practice due to the COVID-19 pandemic. Conclusions: Outpatient paracentesis and gonadotropin-releasing hormone antagonists were perceived as promising interventions. Potential concerns and recommendations around both acceptability and feasibility were raised, which were used to refine the treatment protocols for the Shaping and Trialling Outpatient Protocols for Ovarian Hyperstimulation Syndrome trial.
