To assess the characteristics of scrub typhus clinicalstudies and explore the needs and feasibility todevelop a scrub typhus individual participant-leveldata (IPD) platform
• Systematic review: • 2,647 articles screened
• 99 studies included:
- 8 clinical trials
- 91 observational studies
• 390 case series and reports also identified
• Population: • 9,282 patients in 11 countries enrolled • 14 studies included pregnant participants• 4 studies included HIV positive participants• 9 studies included immunocompromised

• Compared to its magnitude, evidence tooptimise treatment and disease control is sparse
• Treatment recommendations vary by regionsand lack supportive evidence of efficacy
• Existing data collected from past clinical trialsand longitudinal observational studies could be asource of information to address researchpriorities and knowledge gaps
• Systematic literature review of scrub typhusefficacy studies
• Extracted information: Treatments tested,patient characteristics, diagnostic methods,geographical location, outcome measures,statistical methodology
• Inclusion criteria: Clinical trials and longitudinalobservational studies of scrub typhus treatment
• Search done from January 1998 to March 2018
• PROSPERO registration: CRD42018089405

• Data validation in progress• Data analysis and quality assessment to follow• Although only a few scrub typhus clinical trials
found, substantially more data available fromobservational studies
• This work will provide the opportunity tounderstand the landscape of scrub typhustreatment studies and will assess the feasibilityof addressing research questions using IPDplatform and IPD meta-analysis
• Outreach to scrub typhus research community:building IPD platform require extensivecollaboration
We are looking to engage with stakeholders andleaders of the scrub typhus research communityContact: Kartika [email protected] & [email protected]
