PATH Study: People With Injecting Related Infections: Assessing Treatment Outcomes for Those Who Are Hospitalised.

This study will be conducted as a prospective, observational cohort study of adults admitted with invasive bacterial and fungal infectious diseases. This study will be conducted at multiple hospitals in Australia.

Participants will be invited for Screening whilst they are inpatients of the hospital. Participants will be screened for history of injection drug use in the last 6 months and presence of an invasive bacterial or fungal infection.

Eligible participants will be treated through standard of care with the applicable treatment. All participants will commence antimicrobial treatment whilst they are inpatients. For participants who are discharged before planned treatment completion, a hospital discharge visit (Early Discharge Electronic Case Report Form [eCRF]) will be conducted. Following the end of treatment, participants will be reviewed at 6, 12 and 48-weeks post-enrolment. At follow-up visits, behavioural surveys, health-related quality of life, and experiences with hospital care will be assessed.

Individual patient involvement will include four visits over a 12-month period.

The duration of the study is anticipated to be 5 years.
