The Intensive Care Unit (ICU) is a vital department within hospitals, providing care for patients with acute and severe medical conditions [1]. Mechanical ventilation in the ICU is utilized to support patients who are unable to breathe on their own [2]. Within these units, numerous patients on mechanical ventilation remain conscious and frequently encounter substantial communication barriers with their caregivers due to paralysis, weakness, delirium, fatigue, and diminished consciousness. These factors disrupt their ability to communicate through body language and other effective interpersonal communication methods [3–5].
Difficulties in communication between patients and healthcare staff can result in the inability of patients to self-report physiological needs such as thirst, hunger, sleep, and physical symptoms like pain, shortness of breath, and choking sensations, as well as psychological symptoms including sorrow, stress, and confusion [6]. These challenges can exacerbate stress and anxiety, despair, pain, and sleep disorders in patients, potentially influencing physiological indicators like blood pressure, heart rate, respiration, and blood oxygen levels. Moreover, the inability to articulate physiological needs, desires, and pain can lead to increased agitation, aggression, and decreased satisfaction with both communication and the care received [3, 6–11].
A primary concern for ICU patients is the experience of pain resulting from medical procedures, surgical wounds, trauma, fractures, gastrointestinal issues (such as ileus, spasm, constipation), and pressure ulcers [1]. It is estimated that between 50–71% of ICU patients suffer from undiagnosed or untreated pain, with communication barriers being a significant factor in the lack of adequate pain management [12, 13].
Effective and professional communication is a crucial component in the cohesive delivery of nursing care [4]. Communicating with patients who have endotracheal tubes is intricate and challenging, often leading nurses to experience negative emotions such as despair, pressure, incompetence, and moral distress. This is because they are unable to comprehend the patients' needs and provide suitable responses to alleviate their discomfort [4]. Despite nurses' awareness of the importance of effective communication, evidence indicates that such communication with intubated patients is often not achieved [14].
Patients have expressed a need for auxiliary tools that are straightforward and uncomplicated to use, enabling them to communicate their basic, medical, and emotional needs [3, 8]. Many patients are incapable of using technological devices like tablets, and hospital facilities frequently do not offer these tools [15]. Communication methods utilizing illustrated boards have proven to be effective in bridging this communication gap; thus, it is imperative that nurses receive proper training to employ these auxiliary tools when communicating with intubated patients [3, 16].
Illustrated communication skills include the use of images, symbols, and other visual aids for patient interaction [8, 17]. These methods can help patients more clearly express their needs, emotions, and requests, leading to improved nurse understanding of patient needs, fewer misunderstandings, better quality of patient care, and more efficient use of nurses' time and energy [8, 17, 18]. One such tool is the non-electronic illustrated communication board, which is straightforward and cost-effective [19]. These boards display symbols and images representing basic needs, and with the inclusion of the alphabet, they can assist patients in forming words [5].
In Iran, research on the clinical application of illustrated communication boards is scant, and according to the researcher's clinical experience, this beneficial method is underutilized. Moreover, communication disorders between patients and nurses can lead to complications such as inadequate pain management, increased agitation, aggression, stress, anxiety, pressure, and disturbances in physiological indicators (heart rate, respiration, and blood pressure). These issues can also result in a lack of mutual understanding and dissatisfaction with nursing care. Although some nurses may utilize alternative communication methods, the effective use of these methods requires proper training [20]. The impact of training nurses in these communication tools on various outcomes for intubated patients, especially concerning pain and agitation, remains unexplored. Therefore, this study was conducted to determine the effect of training nurses in illustrated communication skills on physiological indicators, pain intensity, agitation, and ease of communication with conscious patients undergoing mechanical ventilation.
