Use of Comfort Theory In Intensive Care

1.1 PROBLEM DEFINITION AND IMPORTANCE

Intensive care units (ICUs) are specialized units where critical care is provided to patients with life-threatening conditions, requiring life-supporting treatment and continuous monitoring. These units operate in intense and stressful environments, utilizing specialized and advanced treatment methods with a multidisciplinary team approach, alongside complex biomedical devices. Patients in the ICU are confined to a limited environment, connected to equipment for treatment and monitoring 24 hours a day. They are exposed to physical factors such as noise, light, room temperature fluctuations, and frequent care and treatment activities. Additionally, patients in the ICU experience emotional challenges and high levels of stress, including being away from their families, witnessing treatments and interventions on other patients, and dependence on healthcare providers for treatment and care. All these complex processes adversely affect the comfort of patients in physical, sociocultural, psychospiritual, and environmental dimensions.

A healthy ICU should be designed to motivate the patient\'s participation in treatment and care, aiming to facilitate recovery. Improving patient comfort in the intensive care unit will enhance the quality of nursing care and shorten the recovery period. Various models and theories exist to enhance and standardize the quality of nursing care with the aim of increasing patient comfort. The Comfort Theory, developed by Kolcaba and based on the nursing function of relief, forms the foundation for nursing care. Kolcaba spent 15 years developing the concept of comfort and its application to patient comfort, creating a taxonomic structure consisting of three levels and four dimensions in 1988. Kolcaba described the concept of comfort, explained holistically, as the current experience of meeting basic human needs for relief, ease, and overcoming problems.

Studies in the literature indicate that high-quality nursing care based on the Comfort Theory positively influences comfort. Patients often report factors that disrupt their comfort after discharge from the ICU and lead to distress, such as sleep-related problems, pain, dehydration, orientation or consciousness disorders, anxiety, loss of appetite, noise, weakness, inability to communicate with the environment, and endotracheal tube application. Conversely, factors that enhance their comfort and make them feel good include feeling safe and the presence of nurses. The main negative environmental features of ICUs reported by patients include high noise levels, artificial lighting, an unfamiliar environment, the presence of complex devices, and the absence of devices such as TV and radio, which reduce comfort. These negative environmental features of ICUs decrease patient comfort and increase the level of stress they experience. Moreover, stressors in the ICU lead to sensory overload, perceptual deprivation, and the development of intensive care syndrome. Stress and related disorders experienced by patients in the ICU have a negative impact on individuals\' health, prolong the healing process, and increase the length of hospital stays.

When reviewing studies that base nursing care on the Comfort Theory in the literature, it is observed that these studies are conducted in various fields of nursing, such as perianesthesia, urogynecology, oncology, cardiology, psychiatry, and end-of-life care. Interventions based on this theory have been found to positively affect patients\' comfort. In Turkey, however, there is limited research on nursing practices based on the Comfort Theory. In a study conducted by Karabacak (2004) with breast cancer patients, it was reported that comfort-supportive nursing care reduced anxiety and increased adherence to radiotherapy. In a study conducted by Yeşim and Türkan (2017), nursing care based on the Comfort Theory in the postpartum period was found to increase the comfort levels of women undergoing cesarean section. Zengin (2012), in his study, emphasized that nursing interventions based on the Comfort Theory, supported by the literature, could be effective in intensive care patients.

Considering the comfort and stress levels of ICU patients, it is necessary to improve and update nursing care, create alternative care methods, and make them applicable to ICU patients. In light of this information, when observations in the ICU and literature information are compiled, it is believed that nursing care structured according to the Comfort Theory will have positive contributions to ICU patients, enhance the quality of care, and guide the development of similar nursing interventions.

1.2 OBJECTIVE OF THE RESEARCH

This study is designed to examine the impact of structured supportive nursing care for intensive care unit (ICU) patients on the environmental stressors perceived by patients in the ICU and on the fundamental factors influencing patients\' comfort at a basic level, including physical, environmental, sociocultural, and psychospiritual factors (such as separation from normal life, restricted communication with family/relatives, and inappropriate environmental conditions).

METHODOLOGY

The study, designed with an experimental design comprising a control group (n:25) and an intervention group (n:25), was planned in accordance with a randomized controlled research design. Initially, the common comfort needs of intensive care unit (ICU) patients were identified, and nursing care plans structured according to the Comfort Theory for ICU patients were created. While patients in the control group were monitored under standard ICU conditions, structured nursing interventions will be applied to patients in the intervention group. The data of the study will be collected using the Patient Identification Form; General Comfort Scale and Intensive Care Unit Environmental Stressor Scale; Parametric tests will be utilized in the evaluation of study data.
