SKin and Soft Tissue Necrotizing INfections in the Intensive Care Unit: a Prospective Multi-national Cohort Study

Conditions
Fournier Gangrene
Necrotizing Soft Tissue Infection
Necrotizing Fasciitis
Registration Number
NCT05116956
Lead Sponsor
Henri Mondor University Hospital
Brief Summary

Necrotizing soft-tissue infections (NSTI) are rare and life-threatening bacterial infections characterized by subcutaneous tissue, fascia or muscle necrosis. Few prospective studies have been performed and our current knowledge on NSTI is mostly derived from retrospective single center studies. The "SKin and soft tissue necrotizing INfections in the ICU" (SKIN-ICU) study is a multinational prospective non-interventional cohort study that will include patients admitted to the ICU/intermediate care unit for NSTI or not.

The objectives of the study are :

1. To assess hospital (i.e., ICU and hospital mortality) and medium-term (day-90 mortality, functional outcomes and health-related quality of life scores, HR-QoL) outcomes

2. To report the clinical presentation and microbiological epidemiology of NSTI and identify independent prognostic factors of mortality and altered quality of life

Detailed Description

Necrotizing soft-tissue infections (NSTI) are rare and life-threatening bacterial infections characterized by subcutaneous tissue, fascia or muscle necrosis. The mortality of NSTIs is high, ranging from 9% in non-selected patients to up to 30% in the most severe forms requiring intensive care unit (ICU) admission .

With an incidence of 4/100 000 persons per year, initial misdiagnosis is frequent, with no reliable diagnostic test available, frequently leading to a delayed surgical debridement of infected tissues, one of the main modifiable prognostic factors. According to international recommendations, any cutaneous infection associated with the failure of one or more organs or showing a dramatic deterioration must include the diagnosis of NSTI for consideration, even if there is no local sign of the condition being severe. The diagnosis is confirmed by identifying during surgery deficient tissue, sometimes necrotic, which comes away easily in the fingers and by the presence of the typical, foul-smelling "dishwasher" exudate.

The early management of NSTIs is challenging and requires a coordinated and multidisciplinary approach. Treatment of NSTIs consists of early broad-spectrum antimicrobial therapy together with emergency and aggressive surgical debridement including excision of all necrotic and infected tissues. Few prospective studies have been performed and our current knowledge on NSTI is mostly derived from retrospective single center studies.The few randomized therapeutic trials testing interventions in this setting have been disappointing, in part because of the difficulty to identify subgroups for individualized treatments. A large international study aimed at collecting granular data on the clinical presentation, microbiology, management and outcomes of patients with NSTI admitted in the ICU and involving a large number of centers and countries is thus desirable to improve our knowledge on this devastating condition.

The "SKin and soft tissue INfections in the ICU" (SKIN-ICU) study is a multinational prospective non-interventional cohort study that will include patients with NSTI admitted or not to the ICU/intermediate care unit and aim at addressing the following points: 1) Hospital (i.e., ICU and hospital mortality) and medium-term outcomes (three- and six-month survival, functional outcomes and health-related quality of life scores, HR-QoL); and 2) Clinical presentation and microbiological epidemiology of NSTI.

mortalityday 90
Secondary Outcome Measures
NameTimeMethod
Health-related quality of life outcomeday 90

EuroQol five-dimensional descriptive system (EQ-5D-5L score). It is based on a descriptive system that defines health in terms of 5 dimensions: Mobility, Self-Care, Usual Activities, Pain/Discomfort, and Anxiety/Depression. Each dimension has 3 response categories corresponding to no problems, some problems, and extreme problems. The instrument is designed for self-completion, and respondents also rate their overall health on the day of the interview on a 0-100 hash-marked, vertical visual analogue scale (EQ-VAS).

Skin grafting and amputationAt day 90

Skin grafting and limb amputation performed within three months of hospital admission will be recorded

Body surface area involvedWithin 24 hours of hospital admission

Quantified with the Wallace rule of nine

SAPS II scoreWithin 24 hours of hospital admission

The Simplified Acute Physiology Score II (SAPS II) is a severity of disease score, which is associated with the probability of death at intensive care unit admission (the greater the value of the SAPS II, the greater the odd of death increases).

Functional outcomeday 90

Activity of daily living (ADL, 6 questions on selfcare, household, employment, shopping, travel, and communication, each rated 0 (best performance), 1 or 2 (worst performance). An ADL score of 12 indicates a high level of dependence.

MicrobiologyDuring the first 72 hours of hospital admission

Microorganisms involved in blood cultures and per operative tissue samples (species, antibiogram, resistance and "difficult to treat" status)

SOFA scoreWithin 24 hours of hospital admission

The Sequential Organ Failure Assessment score is a severity of illness score used in sepsis.the greater the value of the SOFA, the greater the odd of death increases

Anatomic locationWithin 24 hours of hospital admission

Llimbs upper or lower, abdomino-perineal, neck/head, periarticular/circonferential involvement

Portal of entry of the NSTIWithin 24 hours of hospital admission

Portal of entry of the NSTI will be recorder (e.g., skin ulcer, trauma, other)
