Plain English Summary
Background and study aims
Tracheostomy is a commonly performed procedure and is intended to provide a long-term surgical airway for patients who are dependent on mechanical ventilation. Due to its invasive and physiologically critical nature, tracheostomy can be associated with morbidity and have significant effects on patients’ quality of life. The aim of this study is to assess the quality of life of patients undergoing an elective tracheostomy in Intensive Care Units (ICU), revealing late tracheostomy-related complications and conditions for further improving health.
Who can participate?
Patients who were on mechanical ventilation in the ICU and underwent elective tracheostomy, who had the tracheostomy tube removed more than four months ago
What does the study involve?
Participants’ quality of life is assessed using questionnaires. A CT scan and spirometry (breathing) test are performed if needed.
What are the possible benefits and risks of participating?
The benefits of participating are measuring disease impact and assessing quality of life in people undergoing tracheostomy, finding out late tracheostomy-related complications for improving quality of life. A neck CT scan is a convenient and noninvasive way of evaluating problems in the neck. The scan takes little time and is painless. No radiation remains in a patient's body after a CT scan. The x-rays used in standard CT scans have no immediate side effects. There is always a slight chance of cancer from excessive exposure to radiation. However, the benefit of an accurate diagnosis will generally outweigh the risk. The effective radiation dose for this procedure varies. Women should always inform staff if there is any possibility that they are pregnant. CT scanning is, in general, not recommended for pregnant women unless medically necessary because of the potential risk to the baby. Generally, a spirometry procedure is very safe. Some patients report brief shortness of breath or dizziness after the test has been performed, but these will go away after a moment or two. Patients who have recently suffered from a heart attack or any heart-related condition are not ideal candidates for spirometry because the test requires some effort on the patient’s part. In very rare cases, spirometry is known to trigger breathing problems in patients.

Quality of life and late complications in patients undergoing tracheostomy in the ICU
QOL after tracheostomy
The study is taking place for assessment of QOL and revealing late complications in patients who underwent tracheostomy. The SRI questionnaire can reliably measure QOL in mechanically ventilated ICU patients who underwent tracheostomy. It may provide clinicians with an accurate assessment of patients’ quality of life.

Condition after mechanical ventilation and tracheostomy performed in the ICU
Observation of QOL in persons who underwent tracheostomy by filling in the SRI questionnaire. In case of complaints, the cause of the complaints is examined (if needed a tracheal CT scan and spirometry are performed).
Primary outcome measure
1. Airway comfort measured using spirometry at baseline from the fourth month after decannulation
2. Dyspnea measured using the Medical Research Council (MRC) scale at baseline from the fourth month after decannulation
3. Wheezing and whistling while breathing measured using the acoustic value at baseline from the fourth month after decannulation
4. Pain measured using numerical rating scale (NRS) requires the patient to rate their pain on a defined scale from 0–10 where 0 is no pain and 10 is the worst pain imaginable, at baseline from the fourth month after decannulation
5. Scar comfort and scar aesthetic measured using Patient and Observer Scar Assessment Scale (POSAS) at baseline from the fourth month after decannulation
6. Neck mobility restriction measured using the range of back bend neck flexion at baseline from the fourth month after decannulation
7. Voice/speech disorders measured using Individual's Self Assessment of how voice problem affects emotions and self-image and ability to communicate effectively in everyday activities and in social and work settings at baseline from the fourth month after decannulation
8. Sleep disturbance measured using Subjective Assessment Measures by FOSQ-10 at baseline from the fourth month after decannulation
9. Swallowing disorders measured using a simple water swallowing test using standard 150 ml of water. Swallowing process assessed under three categories - swallowing speed (ml/s), swallowing volume (ml/swallow) and swallowing duration (s/swallow) at baseline from the fourth month after decannulation
10. Tracheostomy-related operations measured using anamnesis data: yes/no, if yes which kind of operation
11. Feeling of illness measured using standardized Acceptance of Illness Scale (AIS) at baseline from the fourth month after decannulation
12. Quality of life measured using the Severe Respiratory Insufficiency Questionnaire (SRI) at baseline from the fourth month after decannulation
Secondary outcome measures
1. Tracheal stenosis measured using CT scan, differentiated as mild, moderate and severe stenosis, at baseline from the fourth month after decannulation
2. Granulation tissue formation measured using clinical assessment at baseline from the fourth month after decannulation
3. Tracheocutaneous fistula measured using clinical assessment at baseline from the fourth month after decannulation
4. Tracheomalacia measured using CT scan at baseline from the fourth month after decannulation
