Perception of discomfort by mechanical ventilation patients in the Intensive Care Unit: A qualitative study.

BACKGROUND

Routine care in intensive care units (ICU) results in patient pain and discomfort. While pain is treated with analgesics, discomfort is generally not well characterised or addressed. Since many ICU patients communicate only non-verbally, practitioners often cannot discern between pain or discomfort when treating such patients, potentially leading to inappropriate analgesic administration. A first step in discriminating between pain and discomfort is understanding how patients perceive their discomfort.

OBJECTIVE

To describe mechanically ventilated ICU patients' perceptions of discomfort and how they differentiate discomfort from pain.

METHOD

A qualitative descriptive study using semi-structured interviews conducted with 13 patients in a Medical and General ICU who survived mechanical ventilation. Transcripts were analysed using content analysis.

FINDINGS

Two main discomfort themes were identified: unpleasant physical sensations and unpleasant psychological feelings. Each theme was further divided into subcategories. Most patients did not describe high levels of pain and did not associate physical discomfort with pain.

CONCLUSIONS

Discomfort, as described by patients, stems from both physical sensations and psychological feelings. Pain was less often described as a negative ICU experience, while other non-pain sources of discomfort were more likely to be recalled. Therefore, practitioners should not only focus on treating pain but also on treating overall comfort to improve the quality of the ICU experience and potentially decrease post-ICU psychological sequela.
