The Prevalence and Incidence of DVT in General ICU (preTIME)

October 16, 2020 updated by: Jan Benes, Masaryk Hospital Krajská zdravotní a.s.

The Prevalence and Incidence of Deep Venous Thrombosis in General ICU Patients Receiving Enoxaparine Prophylaxis

Deep venous thrombosis (DVT) represents a major problem in intensive care unit (ICU) patients. Despite the use of recommended pharmacological prophylaxis with low molecular weight heparin (LMWH), the incidence of DVT during ICU stay has been reported between 5 and 15 %. The incidence may vary due to many factors, for example the type of ICU population, the type of protocol of pharmacological prophylaxis and also the type of diagnostic approach. Before formerly planned clinical study targeted to lower DVT incidence by individualizing the dose of LMWH, the investigators decided to evaluate the real DVT incidence in the investigated ICU. The prevalence and incidence will be assessed by ultrasound testing in general ICU patients. on the sample of 200 patients. The investigators hypothesize DVT incidence of 5 %. The compliance to the local DVT prophylaxis protocol will be also evaluated.

Detailed Description

Type of the study: Observational prospective cohort study. Hypothesis: Despite appropriate prophylaxis of deep venous thrombosis in general ICU patients in accordance with the current guidelines, the incidence of deep venous thrombosis is 5 - 10%.

Sample size: 200 consecutive general ICU patients. Inclusion and exclusion criteria: defined in the Eligibility section. Protocol description: All patients admitted to ICU with expected period of the stay longer than 72 hours will be evaluated for the presence of deep venous thrombosis by ultrasound testing during the first 48 hours of ICU stay. Thereafter, each participant will be examined by ultrasound testing twice a week until the discharge from ICU. All patients will receive deep venous thrombosis prophylaxis following the current guidelines. All patients with positive finding of deep venous thrombosis will be managed in accordance with the current guidelines.

Ultrasound examination for deep venous thrombosis: Ultrasound compression test at the following locations: common femoral vein at the groin, deep femoral vein, popliteal vein, both extremities.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Description

All general ICU patients meeting exclusion and inclusion criteria.

Inclusion criteria:

1. General ICU patient with expected length of stay more than 72 hours

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
General ICU patients
No intervention is associated with inclusion to the study (observational study). Included will be all patients admitted to general ICU with ICU stay >72 hours, having deep venous thrombosis prophylaxis appropriate to clinical setting and following the recent guidelines. All study participants will undergo repeated noninvasive ultrasound testing for deep venous thrombosis, which is normal part of the routine care in our ICU.

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
Incidence of deep venous thrombosis
Time Frame: 24 hours from ICU admission to ICU discharge (up to 12 month)
Number of patients with new onset deep venous thrombosis diagnosed during ICU stay (ie deep venoous thrombosis developed after the first 24 hours of ICU stay)
24 hours from ICU admission to ICU discharge (up to 12 month)

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
Prevalence of deep venous thrombosis
Time Frame: From ICU admission to ICU discharge (up to 12 month)
A number of patients with deep venous thrombosis diagnosed anytime during ICU stay (on admission and during ICU stay)
From ICU admission to ICU discharge (up to 12 month)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
