Background
One of the most crucial indicatorsof quality care is safety (Atashzadeh Shoorideh et al. [
1]). Safety refers to the prevention of all unintentional or intentional harm, such as injury or death due to adverse medication reactions, patient misidentification, or nosocomial infections by healthcare providers (Butler and Hupp [
2]). Recently defined by the World Health Organization in 2021, patient safety is a framework of organized activities that establish cultures, processes, behaviors, technologies, and environments within healthcare organizations. This framework aims to consistently and effectively identify risks, preventable harm, and reduce the likelihood of their occurrence (Organization [
3]).
Unsafe care has significantly contributed to serious medical accidents worldwide (AL-Mugheed et al. [
4]), and the social cost of patient injuries has been reported to be in the trillions of dollars annually (Organization [
3]). Hospital-acquired serious injuries account for 6% of occupied hospital beds and about 7 million hospital admissions per year (Butler and Hupp [
2]). Evidence shows that patient safety is a global health concern that affects patients worldwide, including both developed and developing countries (Austin et al. [
5]).
Patient safety is even more crucial in intensive care units (ICUs) because they are among the most critical hospital units where nurses play a vital role (Mahmoudi [
6]). In these units, the risk of adverse events is heightened due to factors such as the complexity of the patient’s condition and treatment, the presence of numerous electronic devices and equipment, patients’ lack of awareness, and their reliance on nurses and life-support equipment (Marzban et al. [
7]). Apart from patients, nurses also face unique challenges like high job stress, extended working hours, burnout, dissatisfaction, moral dilemmas, conflicts with patients’ families, and decisions regarding end-of-life care (LeClaire et al. [
8]).
According to a study conducted in Brazil, factors affecting patient safety in relation to nursing staff included the workload of staff, training and professional qualification of staff, teamwork, contractual employment, lack of job security, and destructive behaviors (Oliveira et al. [
9]). In the study by Naderi et al. (Naderi [
10])in Iran, the factors affecting patient safety include human resources status, management and organization, interaction and teamwork, medications, equipment, medical environment, patient-related factors, improving patient quality and safety, importance of documentation, evaluation and monitoring, medical errors, and barriers and challenges (Naderi [
10]). In a study by Lima et al. (D’Lima et al. [
11]), concepts obtained in relation to employee risk perception and patient safety included employee individual factors (sub-theme including pragmatism versus perfectionism), team factors (two sub-themes including team dynamics and interdisciplinary tensions), unit factors (sub-theme including achieving dynamic balance), and organizational factors (sub-theme including risk perception) (D’Lima et al. [
11]). Another study identified factors such as nurse error awareness, nurse well-being, teamwork, non-punitive environment, work management, hospital leadership, and ICU leadership as effective factors for safe ICU care (Garrouste-Orgeas et al. [
12]).
Vaismoradi (Vaismoradi [
13])conducted a grounded theory study in Iran, presenting strategies aimed at enhancing safe care. These strategies encompassed altering attitudes and performance, eliminating organizational obstacles, fostering a culture of teamwork, enhancing the influence of nursing leadership, and cultivating a culture centered on safe nursing care. Furthermore, Vaismoradi emphasized the importance of redefining safe care and conducting guiding research in this domain as highly impactful strategies (Vaismoradi [
13]).
Despite the existing researches in the realm of factors and elements associated with patient safety, a noticeable gap in within high-risk and critical units like ICUs is evident. Through the implementation of more targeted studies, it is possible to pinpoint the components of safe nursing care in ICUs that align with the cultural contexts and healthcare systems of different countries. The outcomes of this research at a micro level of management can serve as valuable resources for the education and training of nursing students and professionals, while at a macro level, they can inform the development and implementation of healthcare policies. Hence, this study was initiated with the aim of identifying the components of safe nursing care in ICUs.
Materials and methods
Study design and setting
The present study is a conventional content analysis approach, carried out from January 2022 to June 2022. The research was conducted in 8 hospitals affiliated with three medical sciences universities in Tehran, the capital of Iran.
Participants
Through purposive sampling, a total of 21 participants were selected for interviews. The participants included 7 nurses, 2 head nurses, 1 clinical supervisor, 1 nurse responsible for patient safety, 5 intensivists, 2 patients, 1 patient family member (patient’s son), 1 patient safety officer from the Ministry of Health, Treatment, and Medical Education, and 1 paramedic. The initial participant selected for the study was a nurse who met the inclusion criteria, possessed extensive experience, and demonstrated effective communication skills. Subsequent participants were chosen based on the data collected from each participant.
Data collection
In this research, data was gathered through individual, in-depth and semi-structured interviews with individuals who met the specified inclusion criteria. interviews were conducted by the first author and recorded using a mobile device with the participants’ consent.
The inclusion criteria for the healthcare personnel involved having a minimum of two years of professional experience in the ICU or in units associated with patient safety. The selection of the two-year threshold was based on the completion of the mandatory manpower plan course and the acquisition of sufficient experience and knowledge. Patients were included if they had a Glasgow Coma Score (GCS) of 15, demonstrated clear speech abilities, and received approval from the ICU intensivist to participate in the interview.
The researcher took into account the diversity of participants in terms of gender, educational background, job position, and work experience, particularly in relation to the nurses. Data collection persisted until data saturation was achieved, and no new codes emerged. A concluding interview was carried out to confirm data saturation. Field notes were utilized for selecting subsequent samples and extracting the codes. During the initial meeting or telephone conversation, the study’s aims were elucidated to the 21 participants. In a subsequent communication, participants conveyed their decision to either agree or decline participation. Upon agreement, interview schedules were arranged. Notably, only one intensivist declined to participate. All interviews were conducted either at the hospital or the workplace. Prior to interviewing patients, consent was obtained from the intensivist, and schedules were coordinated with the head nurse of ICU to ensure minimal disruption to patient care and treatment processes.
The interviews comprised four parts: initial open questions, main questions, follow-up questions, and closed questions. The formulation of the questions was guided by the interview guide and involved consultation with members of the research team. Subsequently, a pilot interview was carried out to identify any weaknesses, leading to a redesign of the questions (Kallio et al. [
14]) (Table
1).

Data analysis
Data analysis was conducted by the research team, which comprised a nursing doctoral student (first author) and two nursing professors (second and third authors). The first author performed the data analysis, whereas the remaining authors reviewed and made revisions to the codes, subcategories, and categories. The analysis procedures were conducted utilizing the conventional content analysis approach, following the guidelines proposed by Graniheim and Lundman (Graneheim and Lundman [
15]).
Preparation phase
During this phase, decontextualization was conducted in the following manner. Initially, the interviews, and field notes were transcribed using Word software and thoroughly reviewed to capture the main idea. Subsequently, the semantic units were identified and coded. It is important to highlight that the participants were assigned names based on the sequence of the interviews to uphold anonymity. For instance, the first participant was designated as number 1, while the final participant was denoted as number 21.
Organizing phase
Through ongoing comparisons of codes and categories and iterative recategorization during the study meetings with the research team members, a total of 1997 codes were initially identified. Subsequently, through a process of reviewing the extracted codes multiple times, eliminating duplicates, and consolidating similar items, the number of codes was ultimately reduced to 1770. Initially, the codes were organized into subcategories, followed by the extraction of categories from the integration of these subcategories. Finally, themes were derived from the integration of categories. Ultimately, a comprehensive definition of the concept under investigation along with its associated structures was provided.
Reporting phase
During this phase, the processes of sampling, data collection, data analysis, and the subsequent results were documented and reported.
Data integrity and robustness
In this study, the trustworthiness of the results was enhanced by considering strategies in line with Lincoln and Guba’s four criteria for qualitative studies (Lincoln and Guba [
16]).
1-
Credibility: The credibility of this study is supported by the extensive experience of the first author in the research topic. She conducted her Master’s thesis on medication errors in critical care units and has accumulated numerous years of experience working in ICU as a nurse and head nurse. The data collection period was appropriately extended to ensure the researcher’s continued involvement in the study process. Participant selection aimed for maximum diversity in age, gender, work experience, and educational level. Data collection methods included in-depth interviews and field notes. The research process was overseen by a doctoral student in nursing with expertise in qualitative research. The interviews and initial coding were reviewed and approved by the participants, with any ambiguities promptly addressed. The complete transcripts of the interviews, along with the coding, were initially forwarded to the primary author. Following the incorporation of the feedback, the revised text was then shared with the secondary author for further input. The process of assigning codes to subcategories, identifying categories, and developing themes was carried out consistently throughout.
2-
Transferability: This criterion pertains to the richness of descriptive data. In an effort to maximize transferability, participants were purposefully selected from various positions and across different ICUs, such as internal medicine, neurology, surgery, and trauma.
3-
Dependability: It was ensured through the utilization of various data collection methods such as interviews and field notes, along with continuous analysis and precise documentation of all analysis stages. As the current research formed part of a doctoral thesis, all research phases, data analyses, and findings were documented in 6-month reports and reviewed by four referees.
4-
Confirmability: To ensure confirmability, the researcher documented their preconceptions about the study subject to separate them and prevent bias. Additionally, during data collection, the researcher refrained from reviewing the findings of related or similar studies.
Discussion
The present study was conducted with the aim of identifying the components of safe nursing care in the ICUs. Three themes were identified: professional behavior, systematic care, and safety-oriented organization. In this section, the results are compared and discussed with other studies.
The theme of professional behavior emerged by combining the categories implementation of policies, organizing communication, and professional ethics. The participants believe that safe care depends not only on following policies but also on adhering to the principles of professional ethics and organizing communication with all team members and patients.
In term of implementation of policies, Williams et al. concluded that adherence to guidelines can lead to faster diagnosis of sepsis (Williams [
17]), and improves patient safety in medication prescribing (Nouhi et al. [
18]). The results of the study by Santos et al. (Santos [
19]) in Brazil showed that adherence to clinical guidelines leads to better outcomes in patient restraint, positive effect on pain and delirium (Carrothers et al. [
20]; , Thomas et al. [
21]), prevention of falls (Tuma et al. [
22]), and prevention of deep vein thrombosis (Malhotra et al. [
23]). However, it has been argued that adherence to guidelines may jeopardize the autonomy of the nurse, and the nurse may not be able to manage the situation effectively at times not foreseen in the guidelines (Barnard [
24]). For this reason, it seems that, in addition to following the established guidelines, the nurse should have creativity and decision-making power, and be able to identify and prepare for possible out-of-procedure cases for the implementation of each procedure. In the present study, pain control was identified as one of the factors of safe care in the ICU, and most of the participants repeatedly mentioned the pain experience of patients hospitalized in the ICU; in the study conducted in the United States, more than 50% of patients on mechanical ventilation had experienced pain (Fink et al. [
25]). However, in a Norwegian study, only 10% of ICU patients reported pain at rest and 27% reported pain during repositioning (Olsen et al. [
26]). This discrepancy may be due to differences in facilities, equipment, quality of drugs, pain control protocols and nursing methods. It appears that many of the subcategories identified in the professional behavior theme as components of safe care have been introduced and confirmed in other studies. And the results of this study support the previous findings. However, it should be noted that the identification of these components does not necessarily guarantee their implementation, and their implementation requires multilateral planning. For example, despite the importance of safe drug therapy, Ateshzadeh et al. (Atashzadeh Shoorideh et al. [
1])) showed that the level of compliance with drug administration standards was only 2.6% in hospitals under the University of Medical Sciences A in Tehran and 9.4% in hospitals under the University of Medical Sciences B (Atashzadeh Shoorideh et al. [
1]). Regarding infection control, Randa et al. showed that nurses’ performance in hand washing, wearing gowns, gloves and masks was far from the standards (Randa et al. [
27]). Another study found that only 10.83% of nurses avoided incorrect connections (Bayatmanesh et al. [
28]).
The results of this study showed that organizing communication between nurses and other members of the care team is as effective as implementing policies. Haddeland et al. (Haddeland et al. [
29])in Norway demonstrated the importance and need to improve the use of the ISBAR tool to improve patient safety. They concluded that it is essential that healthcare professionals work together to ensure that everyone has the same situational awareness and that good clinical practice is developed and maintained. Correct use of identification wristbands (Barbosa et al. [
30]), accurate recording of all information related to investigations, interventions and their evaluation (Aldawood et al. [
31]), and communication with the patient (Danis [
32])are effective in improving patient safety. The results of the present study are supported by previous studies. In Iran, Abdi et al. (Abdi et al. [
33])concluded that poor communication and lack of team spirit had a negative impact on patient safety (Abdi et al. [
33]). In Saudi Arabia, Al-Dawood et al. (Aldawood et al. [
31])showed that poor team communication was one of the barriers to reducing patient safety in the ICU. Ensuring effective communication is critical to maintaining patient safety and can be achieved by implementing standard communication protocols, providing regular training and education on effective communication, and promoting a culture of collaboration and teamwork (Muller et al. [
34]). Despite the importance of communication to patient safety, the results of evaluations in Iran are disappointing. A review study by Moghadam et al. (Moghadam et al. [
35]), which surveyed Iranian hospitals on the implementation of mandatory patient safety standards, found that the implementation of mandatory standards in the area of ‘interaction with patients and society’ received the lowest score.
According to the results of this research, the principles of professional ethics are necessary to ensure patient safety. The results of studies have shown that things such as respect for privacy (Timmins et al. [
36]), respect for human dignity and worth (Sugarman [
37]; , Smith and Cole [
38]), conscience (Herzer and Pronovost [
39])and professional commitment (Teng et al. [
40]; , Al-Hamdan et al. [
41])are the principles of safe care. The results of the study by Mohammadi et al. (Mohammadi [
42]) in Iran on safe care in ICUs and its relationship with moral courage showed that there is a significant relationship between moral courage and the principles of safe care. In line with previous studies, the present study showed that professional ethics is an important component of safe care in ICUs.
The present study identified holistic care as another effective factor in providing safe care. Holistic care is the systematic and comprehensive care of all systems of the patient’s body. These findings support previous research highlighting the importance of systems thinking and safe care in improving patient safety and overall quality of care (Moazez et al. [
43]). Based on the findings of the study by Wick et al. (Wick et al. [
44]), comprehensive care that addresses the physical, emotional, social and spiritual needs of patients was introduced as a solution to improve outcomes and patient satisfaction. In the study on the design of safe nursing care tools by Rashvand et al. (Rashvand et al. [
45]), attention to the physical needs and attention to the psychological needs of patients were introduced as the main factors of safe nursing care. In addition to the aforementioned studies, the findings of this study are consistent with the holistic and widely used theories in nursing. These include Martha Rogers’ theory, Margaret Newman’s theory and Watson’s theory. A comprehensive review of holistic theories shows that holistic nursing is a two-way human relationship process in which the nurse is attentive, purposeful and alert in the process of caring for the patient as a whole. The result is an improvement in the nurse’s and patient’s sense of wellbeing, quality of care and ultimately patient safety (Yazdi and Talebi [
46]).
In addition to the cases mentioned, the results of this study show the importance of promoting safe care in ICUs through a safety-oriented organizational approach. The creation of a safe environment is also directly related to the safety of the structure and the provision of safe equipment. In line with the present study, Naderi et al. (Naderi [
10])also introduced in their study the state of human resources, management and organization, interaction and teamwork, equipment, environment, and evaluation and monitoring as the main factors affecting patient safety in the hospital (Naderi [
10]). In the study by Lima et al. (D’Lima et al. [
11]), organizational factors were identified as a threat to patient safety. This means that when employees perceive a risk from the organization, they stop providing safe care to patients. In Oliveira et al.’s study (Oliveira et al. [
9]), employee workload, training and professional qualifications, teamwork, contractual employment, lack of job security and disruptive behavior were introduced as factors that interfere with patient safety. In the theoretical model of safe care presented by Vaismoradi (Vaismoradi [
13]) the removal of organizational barriers was identified as one of the strategies to improve patient safety . Thus, based on the results of the present study and other studies, it can be said that healthcare organizations play an important role in patient safety.
Research limitations
One of the limitations of the current study was the absence of theories related to patient safety, which compelled the researchers to resort to the conventional content analysis method.
Another limitation was the lack of specific studies in ICU departments, which made it difficult to compare the present study with similar studies.
In the present study, despite the use of observations and field notes, the primary method of data collection was interviewing the participants. In future studies, incorporating other data collection methods can enhance the depth of the study.
The researcher’s extensive background in working in the intensive care unit as a nurse and head nurse, along with their familiarity with non-safe care practices, posed a risk of introducing bias. To mitigate this bias during the interviews, the researcher endeavored to adopt a listening role and formulate questions in accordance with the interview guide.
A significant portion of the patients admitted to the ICU did not qualify for inclusion in the study as a result of their diminished level of consciousness, reliance on mechanical ventilation, and administration of sedative and hypnotic medications. Identifying suitable participants proved challenging, necessitating extensive consultations and diligent follow-up by the researcher.
Patients exhibited caution in sharing their negative experiences due to concerns about potential repercussions from staff. Building trust to encourage open communication without self-censorship proved to be a lengthy endeavor. In addition, in one particular case, the patient expressed concern about the proximity of her bed to the nursing station, fearing that her conversations would be overheard by the nursing staff. Consequently, in adherence to the patient’s comfort and in consultation with the anesthesiologist, the interview was relocated to a different room to ensure confidentiality and optimal clinical conditions.
Due to the COVID-19 pandemic and the associated restrictions on patient visits, access to the patient’s family was difficult. The researcher had to make several attempts to make appointments for interviews.
Conclusion
The provision of safe care in the ICU is influenced by various components. According to the findings of this study, nurses exhibit professional behavior, such as implementation of policies, organizing communication with team members, patients, and their families, and adherence to professional ethics. They also demonstrate holistic care by following the nursing process and considering the entire system. Conversely, healthcare organizations play a crucial role in ensuring safe care by providing appropriate equipment and maintaining environmental safety. A safety-focused organization can enhance the delivery of safe care to patients in the ICU by offering a secure environment and reliable equipment. This not only ensures patient safety but also boosts staff efficiency, reduces error risks, and ultimately enhances patient outcomes and overall care quality. Healthcare organizations can establish conditions for safe patient care by recruiting suitable staff, monitoring their performance, and addressing their training requirements. Competent nurses, through the provision of comprehensive and systematic care, can deliver safe and high-quality services to patients. It is imperative to emphasize that achieving the desired outcomes necessitates collaborative efforts among healthcare organizations, nurses, and other healthcare professionals.
