  1. Critical Illness is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Burns.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Catheter-associated urinary tract infections (CAUTI) are the most common nosocomial infections in critically ill patients and are responsible for high morbidity rates, increased hospital stays and associated costs.

The purpose of this study is to evaluate whether active drain line clearance by the Accuryn Monitoring System reduces the incidence of CAUTI in hospitalized patients requiring catheters.

Read the detailed description

Urinary tract infection (UTI) is the most common healthcare associated infection (HAI) acquired in hospitals and is estimated to account for approximately 13% of hospital infections in the United States, of which 75% are associated with indwelling urinary catheters. It is estimated that between 12-16% adult inpatients will receive an indwelling urinary catheter during their hospital stay. The rate of catheter-associated UTI (CAUTI) are highest in burn ICUs, followed by inpatient medical wards and neurosurgical ICUs.

The purpose of this study is to evaluate whether active drain line clearance by the Accuryn Monitoring System reduces the incidence of bacteriuria and/or CAUTI in patients requiring catheters for more than 72 hours. This study will also evaluate the efficacy in reducing bacteriuria of the Accuryn silver fabricated silicone catheters.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Adult (age ≥ 18)
  2. Patient or Legally Authorized Representative (LAR) possess the capacity to provide
  3. Indication for a urinary bladder catheter (or one currently in place)
  4. Expected urinary catheter requirement ≥ 72 hours
  5. No current urinary tract infection
  6. No current indication for prophylactic antibiotics. If a surgical patient, receive perioperative antibiotics for no greater than 24 hours

Exclusion criteria

Exclusion Criteria:

  1. Inability to receive a urinary bladder catheter
  2. Chronic suprapubic catheter in place
  3. Expected survival \< 72 hours
  4. Receipt of systemic antibiotics within 48 hours of enrollment, other than prophylactic antibiotics given at the time of surgery
  5. Surgery of the genitourinary tract in the past 6 months prior to admission
  6. Deemed unfit for the protocol by the investigator for any reason
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Difference in percentage of catheter-associated bacteriuria

    To study the difference in rate of catheter-associated bacteriuria between SOC catheters and Accuryn silicone or Accuryn silver-doped catheters with active drain line clearance.

    Time frame: 30 days

Secondary outcomes

  1. Percentage of asymptomatic (ASB) and symptomatic (CAUTI) bacteriuria

    To study the incidence and progression of asymptomatic bacteriuria and CAUTI in patients with prolonged foley catheters for greater than 72 hours.

    Time frame: 30 days

  2. Time to Bacteriuria (ASB and CAUTI)

    To study the progression of asymptomatic bacteriuria and CAUTI in patients with prolonged foley catheters for greater than 72 hours.

    Time frame: 30 days

  3. Urine Culture Comparisons

    To study the correlation between patient urine cultures and cultures taken from the Foley (Foley tip, urine sampled from collection bag).

    Time frame: 30 days
