PROCALBAN: Use of Procalcitonin, a Blood Test to Guide Antibiotic Therapy for Sepsis in Adults
Study Details
Study Description
Brief Summary
Trial design:
Randomised controlled, two-arm, parallel, clinical trial to assess the efficacy and safety of sequential daily procalcitonin assessments to guide de-escalation of empirical antibiotic therapy in adult patients with sepsis.
Trial settings Trial site is Chattogram Medical College Hospital (CMCH), Bangladesh. CMCH is tertiary care hospital with undergraduate and postgraduate teaching facilities. This tertiary hospital receives referrals from urban and rural areas of southern Bangladesh and has basic facilities for intensive care and haemodialysis.
Trial Participants:
Male or female hospitalised patients, 16-65 years of age, with confirmed or suspected sepsis
Patients (Total 532) will be 1:1 randomised to either:
-
Intervention arm: daily measurement of serum procalcitonin concentrations to guide de-escalation of antibiotics (Intervention arm: 266), or
-
Control arm: standard of practice to guide de-escalation of antibiotics without procalcitonin assessments (Control arm: 266).
Patients will be followed-up until ICU discharge and/or hospital discharge with an additional follow-up at 28 days after discharge.

Outcome Measures
Primary Outcome Measures
- Length of antibiotic treatment [Through study completion, an average of 1 month]
number of days of antibiotic treatment during the hospitalisation period.
Secondary Outcome Measures
- Consumption of antibiotics expressed as the Defined Daily Dosage (DDD) [Through study completion, an average of 1 month]
Defined daily dose (DDD) is the assumed average maintenance dose per day for a drug used in its main indication in adults.
- Days of therapy with antibiotics (DOT) [Through study completion, an average of 1 month]
Definition of DOT: One DOT represents the administration of a single antibiotic on a given day regardless of the number of doses administered or dosage strength. If a patient receives more than one antibiotic it will be added on with DOT of the first antibiotic.
- Number of days of parenteral antibiotic during hospitalisation period [Through study completion, an average of 1 month]
Number of days of parenteral antibiotic from the day of enrolment to the day of stopping of parenteral antibiotic during hospitalisation period
- Overall mortality, mortality associated with recurrent infection and non-lethal recurrent infections. [Through study completion, an average of 1 month]
Recurrent infections include culture positive relapse (failure of initial eradicative treatment for the original infecting strain), culture negative relapse (recurrence of initial symptoms within 2 days of stopping antibiotics) and reinfection (infection with a different strain of the same species). Recurrent infections are defined as growth of one or more of the initial causative bacterial strains (i.e., same genus, species) from a second sample taken from the same infection site after stopping of antibiotic therapy, combined with clinical signs and symptoms of infection. Superinfection is defined as the isolation from the same or another site of one or more pathogens different from that identified during the first infectious episode, together with clinical signs or symptoms of infection.
- Duration of hospital stay (ICU/ general ward) [Through study completion, an average of 1 month]
- Proportion of patients with infections caused by antibiotic resistant bacteria [Through study completion, an average of 1 month]
- Direct medical costs of prescribed antibiotics, the assessment of serum procalcitonin (PCT assay) and hospital stay cost. [Through study completion, an average of 1 month]
