Acute and Persistent Pain in ICU Patients (PAIN-ICU)

October 3, 2022 updated by: Tampere University Hospital

Acute and Persistent Pain in Intensive Care Patients

Approximately 20,000 patients are treated in intensive care units (ICU) in Finland annually. During ICU stay many diagnostic and other procedures as well as immobilization and underlying diseases may cause pain. Therefore the incidence of pain in ICU patients can be high. Acute pain may cause several detrimental effects including respiratory distress, tissue hypoxia, immunosuppression and anxiety. After discharge many survivors of critical care have lower health-related quality of life, symptoms of post-traumatic stress disorder or persistent pain.

Only few studies with a focus on acute or persistent pain in ICU patients have been made, hence the incidence and risk factors for ICU-related pain is not very well known. Some of the identified risk factors for persisting pain may be increased age, sepsis or inadequate pain management during ICU stay. Opioids are most often used for analgesics in intensive care. Because they may have several adverse effects the use must be based on validated pain scales. Many factors such as sedation, relaxation or delirium of the patient complicates the management of the pain.

This prospective observational study aims to determine the incidence and risk factors for acute and persistent pain in ICU patients as well as and the use of analgesics during intensive care.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This prospective observational study aims to determine the incidence and risk factors for acute and persistent pain in ICU patients as well as and the use of analgesics during intensive care.

The recruitement process is finished, but the follow-up is on-going. Patients are followed-up by subsequent questionnaires until 5 years after admission to the ICU.

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.

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 acute pain
Time Frame: Through study completion, an average of 3 days
Moderate or severe pain (numerical rating scale (NRS) value above 3 / critical pain observatory tool (CPOT) value ≥3) during intensive care
Through study completion, an average of 3 days
Incidence of persistent neuropathic pain using Pain Detect
Time Frame: At intensive care follow up clinic at three months after discharge and thereafter the change in pain annually for 5 years
Moderate or severe pain.
At intensive care follow up clinic at three months after discharge and thereafter the change in pain annually for 5 years
Incidence of anxiety affecting persistent pain
Time Frame: At intensive care follow up clinic at three months after discharge and thereafter the change in anxiety annually for 5 years
State Trait anxiety Index T (STAI-T)
At intensive care follow up clinic at three months after discharge and thereafter the change in anxiety annually for 5 years

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
Analgesic use
Time Frame: Through study completion, an average of 3 days
Analgesics administered during intensive care including indications and dosages
Through study completion, an average of 3 days
Delirium
Time Frame: Through study completion, an average of 3 days
Incidence of delirium during intensive care by using Intensive Care Delirium Screening Checklist (ICDSC, scores 0-8) scale, a sum of symptoms equal or above 4 is considered affirmative for delirium
Through study completion, an average of 3 days
