Process Mapping and Data Collection to Inform a Computer Simulation Model of Hospitalised Patients With Bloodstream Infection, Sepsis and Systemic Infection
The goal of this study is to create a computer simulation of patients with bloodstream infection to understand how changes in healthcare policies and resources affect patient treatment. This simulation will help doctors and health-care decision makers make better choices in treating these patients and avoid overusing antibiotics that can lead to antibiotic resistance. Antibiotic resistance is when bacteria can't be killed by antibiotics anymore. Participants will not receive treatments as this is an observational study, but the study will involve:

Interviews with healthcare staff to understand patient care pathways.
Analysis of historical data on bacteria causing infections and antibiotic treatments.
A 30-day observational study to observe patient treatment for bloodstream infections.
- EligibilityCriteria: Inclusion Criteria:  Sub-study 2 (retrospective data collection)  Patients who were managed within a LUFT acute hospital site (Aintree or Royal) and had a concurrent blood culture investigation requested Age ≥ 18 years at the time of the study. Sub-study 3 (observational study) Patients with blood culture investigation requested during the observation period, and staff caring for the patients.
