NCT06867458

Brief Summary

This is a single-center, non-blinded, prospective, pilot study enrolling patients admitted to the critical care unit at Royal Columbian Hospital. This study investigates the effects of universal nasal decolonization using antimicrobial photodynamic therapy (aPDT) on the prevention of hospital-acquired pneumonia (HAP), ventilator-acquired pneumonia (VAP), and hospital-acquired bloodstream infection (BSI) in this patient population. Main Objectives include:

  • To determine whether a large, multi-center RCT of this protocol is feasible
  • To determine baseline rates of VAP, HAP, and ICU-acquired BSI
  • To gather preliminary efficacy data regarding VAP, HAP, and ICU-acquired BSI prevention using universal aPDT nasal decolonization
  • To gather preliminary microbiological data on the effect of universal aPDT procedures on nasal carriage of various microoganisms in ICU patients.

Outcome Measures

Primary Outcomes (1)

  • Protocol Adherance

    During each day of the study, members of the research team will track adherence to the nasal swab and nasal decolonization procedures (during the intervention phase) for all patients enrolled in the study. A standardized checklist will be developed and used to track protocol adherence.

    Entire study duration- 4 months

Secondary Outcomes (11)

  • Change in nasal bacterial load

    Entire study duration- up to 4 months

  • Preliminary Microbiology Data

    Entire study duration- up to 4 months

  • HAP incidence

    Entire study duration- up to 4 months

  • VAP incidence

    Entire study duration- up to 4 months

  • ICU-acquired BSI incidence

    Entire study duration- up to 4 months

  • +6 more secondary outcomes

Study Arms (2)

Control Arm

NO INTERVENTION

The first two months will constitute the control period before the aPDT intervention is introduced into the unit. No nasal decolonization procedures (current standard of care) will take place at this time. All patients enrolled in the study will receive a nasal swab upon ICU admission, and once every four days during their stay.

Intervention Arm

EXPERIMENTAL

Nasal decolonization procedures will be administered every other day. Just as during the intervention period, a nasal swab will be administered every four days to assess the microbiology of the nose prior to the scheduled nasal decontamination treatment

Device: Antimicrobial photodynamic therapy (aPDT) nasal decolonization device

Interventions

aPDT is a technique that employs a specific wavelength of light to activate a photosensitizer substance. Once activated, this photosensitizer reacts with surrounding molecules to produce radicals and reactive oxygen species. When activated in the presence of microorganisms, these molecules serve to disrupt membrane structure and protein cross-linking, leading to their death.

Model Details: The pilot study will take place over four months at the Royal Columbian Hospital (RCH) Intensive Care Units. All patients who meet inclusion/exclusion criteria will be enrolled via a waived consent procedure. The first two months will constitute the control period before the aPDT intervention is introduced into the unit. All patients enrolled in the study will receive a nasal swab upon ICU admission, and once every four days during their stay. Following the control period, the intervention period will commence with the introduction of the aPDT device to all eligible patients. Nasal decolonization procedures will be administered every other day. Patients will undergo one follow-up visit at 4 days post ICU discharge.
