Tags for Tears: The Obstetric Anal Sphincter Injury Hashtag Ontology Project.

Importance: Social media is a powerful outlet for the dissemination of health care information. Adoption of a hashtag ontology-a standardized list of terms-may help better organize information and improve access to educational materials for health care providers (HCPs) and patients.

Objectives: The primary objective was to create a hashtag ontology specific to obstetric anal sphincter injuries (OASIS) based on Twitter usage. Secondary objectives included (1) performing a thematic analysis of OASIS-related tweet content and (2) reporting the type of users posting about OASIS.

Study design: This study was an analysis of tweets related to OASIS posted between June 1, 2019, and June 1, 2022. Symplur Signals (a Twitter analytics software) (Symplur LLC, Los Angeles, CA) was used to identify relevant tweets based on predetermined search terms. Hashtags were reviewed by social media influencers to create a finalized ontology list. The top 100 tweets underwent thematic analysis and were grouped based on emergent themes. Types of users posting about OASIS were also analyzed.

Results: Symplur identified 660 tweets related to OASIS. The final ontology included the following 8 hashtags: #OASIS, #perinealtrauma, #birthtrauma, #3rddegreetear, #4thdegreetear, #episiotomy, #operativedelivery, and #postpartumbody. Major tweet content themes included education, self-promotion, patient experience, medical-legal, research, and opinions. Educational tweets surrounded prevention, risk factors, complications, and educational events related to OASIS and perineal trauma. Of the educational tweets, only 30% were posted by HCPs.

Conclusion: This study created a standardized hashtag ontology related to OASIS. Less than one third of educational tweets were posted by HCPs.
