The Use of PlCO-Vacuum-System on Sternal Wounds (PICO sternal)

November 27, 2024 updated by: University of Giessen
The use of a vacuum-assisted wound closure system (PICO, Fa. Smith & Nephew) is being investigated to determine whether it reduces the incidence of sternal wound healing disorders compared to conventional wound care with plaster.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Median sternotomy remains the standard surgical approach for most cardiac surgeries. However, postoperative wound infections can occur and may progress to mediastinitis, a life-threatening complication with significant mortality. This risk is particularly pronounced in cases where sternal perfusion is compromised, such as when one or both internal mammary arteries are harvested during coronary artery bypass grafting. In such scenarios, the incidence of sternal wound healing disturbances is estimated to range from 2% to 7%.

Several strategies aim to reduce the risk of sternal wound infections. One approach involves external stabilization using a thoracic vest, which has been shown to significantly decrease sternal instability and healing disorders when implemented early in the postoperative period. Another approach utilizes negative pressure wound therapy, which has demonstrated efficacy in reducing sternal wound healing complications in prior studies involving systems like Prevena (Fa. KCI).

The PICO-System operates with a distinct vacuum pressure mechanism and a unique film design compared to the Prevena system. To date, no prospective randomized studies have evaluated the PICO-System for its effectiveness in reducing sternal healing disturbances, sternal instability, and mediastinitis. This study aims to compare conventional plaster wound care with the PICO vacuum system in a randomized, prospective design, assessing outcomes up to six months postoperatively.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Infection at 30 POD
Time Frame: until day 30 post-surgery
Rate of superficial or deep sternal wound healing disorders at 30 days postoperatively
until day 30 post-surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Infection at 180 Postoperative Days (POD)
Time Frame: Up to 180 days post-surgery
Rates of superficial and/or deep sternal wound healing disorders assessed using standardized clinical criteria, including infection signs (e.g., erythema, purulent discharge), radiological imaging (if indicated), microbiological culture results, and adherence to validated classification systems such as the CDC's surgical site infection (SSI) criteria.
Up to 180 days post-surgery
Patient satisfaction
Time Frame: until day 7 post-surgery

Patient satisfaction with the PICO-System in comparison to conventional plasters:

The following questions were assessed to evaluate participant satisfaction:

  • The wound dressing causes discomfort.
  • My wound has achieved a satisfactory cosmetic appearance.
  • I experienced pain during wound dressing changes.
  • I am generally satisfied with the care provided.

For each question, the following response options were offered:

  • Fully applies
  • Partially applies
  • Neutral
  • Partially does not apply
  • Does not apply
until day 7 post-surgery

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cost-Effectiveness of PICO Wound Dressing Compared to Conventional Plaster Dressing
Time Frame: From surgery to day 180 post-surgery
The cost-effectiveness analysis will assess the direct and indirect costs associated with the use of PICO vacuum-assisted wound dressings compared to conventional plaster dressings in patients undergoing median sternotomy. Costs will include initial purchase price, frequency of dressing changes, associated resource utilization (e.g., hospital readmissions, additional interventions for wound healing disorders), and postoperative complications such as sternal instability, wound infections, and mediastinitis. Data will be aggregated and reported using descriptive statistics, incremental cost-effectiveness ratios.
From surgery to day 180 post-surgery
