Background: The perioperative nurse’s job content becomes highly extensive in the 21st century. This makes then users more frequently exposed to various degrees of hazards. However, little is known about rates and patterns of operating room hazards among Nigerian perioperative nurses. Aim: To investigate the rates and patterns of operating room hazards among Nigerian perioperative nurses. Methods: A cross-sectional descriptive survey of all Nigerian perioperative nurses who attended the 15th Annual Scientific Conference of National Association of Perioperative Nurses of Nigeria (NAPON) in Sokoto between Monday 12th and Friday 16th October, 2015 was undertaken. An adapted and modified questionnaire on impact of operating room occupational hazards on intraoperative nurses was used for this study. The questionnaire was modified in content to include questions on rates and patterns of room hazards among perioperative nurses. Statistical analysis was performed using the descriptive (frequency, percentages, mean and standard deviation) and inferential operating statistics (Spearman’s correlation coefficient). The level of significance was set at p < 0.05. Results: This study involved 92 Nigerian perioperative nurses among the conference attendees who gave consent to participate in this study. Males constituted 58 (63.0%) of the study population and 80.0% of the participants were between the age of 31 and 60 years, with a mean age of 44.7 (± 9.5) years. The prevalence rate of operating room hazards among Nigerian perioperative nurses was 77% and a similar portion (72%) of the participants in this study indicated being occasionally exposed to daily hazards related to factors at workplace. Nearly two-third (64%) of the participants affirmed being occasionally exposed to accidental type of hazards. There were statistical significant relationship between sex (p = 0.030), (p = 0.026), age group (p = 0.002), years of experience (p = 0.003), rank (p = 0.0033), (p = 0.003), workplace health facilities (p = 0.001), (p = 0.047) and workplace geopolitical zones (p = 0.040) with participants' exposure to operating room hazards and the overall rating of their operating room working condition. Conclusion: The rate of operating room hazards among Nigerian perioperative nurses is high. This demonstrates a need for more professional consciousness on the concepts of educational and practical interventions practices on ways of identifying and preventing different types of hazards not only among perioperative nurses but also for other similar professional groups can significantly reduce the risk of hazards exposures
Perioperative nurses (PON) were formally referred to as operating room nurses (ORN), a term that was historically referred to patient care provided in the intraoperative period and practice within the operating room itself. However, as the responsibilities of the operating room nurses expanded to care for surgical patients in the preoperative and postoperative periods, the term “perioperative” was recognized as more appropriate [1,2]. The perioperative nurse is a nurse who specializes in perioperative practice and who provides nursing care to all surgical patients throughout the continuum of surgical care .
Perioperative nurses function in various roles, including those of manager, clinical practitioner (e.g., scrub nurse, circulating nurse, and clinical nurse specialist), educator and researcher. In these roles, PON responsibilities are further expanded to include perioperative patient assessment, patient and family teaching, patient and family support and reassurance, patient advocacy, control of the OR environment, efficient provision of resources, coordination of activities related to surgical patient care, communication, collaboration and consultation with other healthcare team members, maintenance of aseptic and sterile techniques, on-going monitoring of the patients physiological and psychological status, supervision of patients care assistant, management of equipment, instruments, supplies and mediate between various hospitals, departments, the surgeons, and the management .
In recent years, OR occupational hazards and nurse’s occupational safety have became a global occupational and public health issues. The health and well-being of working people and their families are greatly influenced by the quality of their work environments . Occupational Safety and Health (OSH) programs have traditionally been concerned with reducing hazardous exposures at work that can lead to workrelated injury, illness, and disability. The joint committee of International Labor Organization (ILO) and the World Health Organization (WHO) adoption of OSH in 1950, it has gained a lot global importance on the health and safety at work matters that relate to the general health and well-being of working people  and that should be given consideration in policies at all level. Health and safety problems at work are, in principle, preventable and should be prevented by the use of all available tools, legislative, technical, research, training and education, information, and economic instruments. The goal of all occupational health and safety programs is to foster a safe work environment .
Operating room (OR) environment, functions as a site of performing surgical treatment to patients, is of great importance in the hospital among other healthcare settings. The nature of surgeries makes characters of nurse’s work in the OR to be fast-paced, highloaded, and changeful. With the rapid development of medical science, technology and model, ORN job content becomes highly extensive in the 21st century and their responsibilities involve not only basic medical caring, scrubbing and circulating, and anesthetic skills, but as well as engineering and technical skills .
Right from inception, OR environment is basically a closed, isolated, restricted, yet flexible environment charged with multiple inherent risks for both surgical team and the patient brought for surgical treatment. OR environment requires coordinated and well-directed team effort [8-10]. The complexity of surgical working environment is determined by various occupational hazards and risks ranging from accidental, physical, chemical, biological, ergonomic, psychosocial and organizational hazards (Table 1), and all of these, could potentially affect and threaten perioperative nurses physical and psychological health and well-being in varying degrees [11-13].

Hazard is a generic term for any situation or state of events which poses a threat or harm  and work-related hazards are the risk to the health of a person usually caused by unsafe working environment [15,16]. Johnson’s  equally defines risk as the combination of severity, consequences and likelihood of occurrence of undesirable outcomes.
Internationally, it is estimated that about 2.9 billion workers are exposed to hazardous risks at their respective workplaces , likewise the international labor organization statistics revealed that, every day, 6,300 people die as a result of occupational accidents or work-related diseases, which are more than 2.3 million deaths per year. Over 337 million accidents occur at work annually; many of these resulting in extended absences from work. The human cost of this daily adversity is huge and the economic burden of poor occupational safety and health practices is estimated at 4 per cent of global Gross Domestic Product each year . There is ample evidence that occupational hazards account for 4% of all cancer deaths. The National Safety Council (NSC) has stated that hospital employees are 41% more likely to lose time from work because of injury or illness than employees in other fields. Hospital employees who work in or around laboratories or operating rooms are more likely to be injured by exposure to medical gases than workers in other areas . Furthermore, in Nigeria, a study by  reported annual mortality rate of 1,249 per 100,000 workers.
In recent years, OR nurse’s job content becomes highly extensive in the 21st century which makes ORN more frequently exposed to various degrees of hazards [10,13,20]. OR hazards have direct and indirect spillover effects on the surgical patient which may further compound the client’s health problems with unpleasant consequences; these undesirable effects of the hazards are usually irreversible . The effects of a hazardous working condition range from injuries to occupational diseases .
To describe frequency and patterns of operating room hazards reported by Nigerian perioperative nurses.
The study was carried out at the 15th Annual Scientific Conference of National Association of Perioperative Nurses of Nigeria (NAPON) held at Sultan Macchido Institute of Quranic and General Studies Sokoto, Sokoto State between Monday 12th and Friday 16th October, 2015.
NAPON Annual Scientific Conference is an annual event tailored to congregate all perioperative nurses all over the federation to brainstorm on ways of improving the standards of perioperative nursing practice all over Nigeria and to increase patients’ satisfaction through quality surgical nursing care .
A cross-sectional descriptive survey of Nigerian perioperative nurses.
The sample was a convenience sample. All attendees of the NAPON conference (15th October, 2015) were invited to participate. Inclusion criteria included perioperative nurses working in government and non-government health care facilities in Nigeria. Exclusion criteria were all non-perioperative nurses who attended the conference.
Data collection tools
The instrument used for this study was a questionnaire adopted from Jingke  study. The questionnaire was modified by the researchers to identify the participants’ rates and patterns of operating room hazards. Hazards were categorized into five major hazard groups and the participants were asked to rate the frequency and the severity of each categorical hazards they were expose to using 4 and 5-level Likert scales. The rating scale ranged from ‘1’–never, ‘2’–occasionally, ‘3–often, ‘4’–very often for frequency rating and 1’–minor, ‘2’– moderate, ‘3–major, ‘4’–catastrophic for severity rating [24,25]. The questionnaire was earlier distributed among 15 perioperative nurses who were at different ranks at Ahmadu Bello University Teaching Hospital Zaria in September 2015 for content validity. The suggested corrections were made and the revised questionnaires were administered to the participant at the conference. The researchers sought for permission and introduction from the authorities of the association to carry out the study and a written informed consent of each participant was also obtained.
Data analysis and management
Data were screened, then coded and computed into SPSS version 16.0 for windows for analysis. Statistical analysis was performed using the descriptive (frequency, percentages, mean and standard deviation) and inferential statistics (Spearman’s correlation coefficient). The level of significance was set at p < 0.05.
A total of one hundred and six questionnaires were distributed and ninety two were duly completed and valid for analysis, giving a returnrate of 87%. Males constituted 58 (63.0%) of the study population and 80.0% of the participants were between the age of 31 and 60 years, with a mean age of 44.7 ± 9.5 years. All participants have dual nursing professional qualifications and (20.7%) had Bachelor of nursing science degree certificates. Participants work experience showed that 74 (82.6%) of them had spent between 1-20 years in practice as registered perioperative nurses in the operating theatre. Fifty one (53.2%) of the participants were on the rank of Chief Nursing Officers and Assistant Chief Nursing Officers. More than half (64.1%) of the participants worked with federal / tertiary health facilities and a third (34.8%) were from the north-west zone where the conference was held. Majority (n = 70, 77.0%) of the participants reported that they had experienced different types of hazards in the operating room while 20 (22.0 %) indicated that they had never experienced any form of operating room hazards before (Figure 1).
Figure 2 below depicts that 66 (71.7%) of the participants reported been occasionally exposed to daily hazards related factors at workplace.
Table 2 below reveals that nearly two-third 59 (64.1%) of the participants affirmed been occasionally exposed to accidental hazards while, it is significant to note that nearly two in every five 42 (45.7%) of the participants attested that they have never encountered any form of chemical hazards before.
|Types of hazards||Very often (%)||Often (%)||Occasionally (%)||Never (%)||Unsure (%)|
|Accidental||2 (2.2)||3 (3.3)||59 (64.1)||23 (25.0)||5 (5.4)|

Findings of this study revealed a high prevalence rate 77% of operating room hazards among the participants and 72% of them were occasionally exposed to daily hazards and hazards-related factors at workplace. This findings is agreement with similar studies carried out among industrial and non-industrial workers that recorded high prevalence rates of 80% and 97.7%) across the occupational groups [26-28]. Likewise, studies [29-31] reported that on daily bases at workplace, workers are confronted with health and safety issues which are attributed to hazardous and stressful working environments.
Work schedule and the design of the workplace can lead to errors and accidents [32,33]. OR hazards can be ascribed to many factors such as the complexity nature of surgical working environment charged with multiple inherent of both potential and actual hazards [11,12]. Unrealistic workloads, unfinished tasks and high nursing attrition rates, long work duration, overtime and number of hours worked per week and so on, were reported to have significant effects on perioperative nurses as they carried out their daily duties and responsibilities combined with prolong standing posture in which those activities are being carried out .
Due to the complex nature of the OR, perioperative nurses do encounter series of hazards that are categorized into biological hazards, chemical hazards, physical hazards, and psychosocial hazards  Significantly, the finding of this study shows that more than half (55.4%) and three in every five (62.0%) of the participants were majorly exposed to minor level of accidental and physical hazards in the operating rooms. This finding is in line with a study of  who reported that most of the perioperative nurses were more frequently affected by accidental, physical, chemical and organizational hazards at work than the nurse anesthetist.
The frequency of operating hazards experienced by the perioperative nurses varied from never to very often for patterns and the severity of the hazards exposures were rated from minor to catastrophic. These reports could be attributed to different nature of the health facilities and the working conditions of the operating rooms of the participant’s workplace. In this study, it was observed that 64% and 58% of the participants affirmed that they were frequently and occasionally exposed to accidental and physical hazards. Another evidence from this study is that 55% and 62% of the study participants rated minor for both accidental and physical hazards as the most severely encountered at their respective place of work.
Participants opinions on the frequency of exposures to hazards in the operating room illustrates that long working hours 74%, low back pain 73% and fatigue 67% were the three major types of hazards encountered among the participants in this study. This finding corroborates findings of previous studies [1,35] who reported prevalence of low back pain of 71% and 77% among nurses. This study established significant association between gender (p = 0.030), (p = 0.026), age group (p = 0.002), years of experience (p = 0.003), rank (p = 0.0033), (p = 0.003), workplace health facilities (p = 0.001), (p = 0.047) and workplace geopolitical zones (p = 0.040) with operating room hazards, frequency and severity rating of the various hazards encountered and the overall rating of their operating room working condition as shown in Table 3. This is consistent with studies by [36-41] that found correlations with participant’s exposure to occupational risk, hazards, sex, age, workplace and professional rank of the participants.
Most Nigerian perioperative nurses could not attend the conference due to the security challenges (Boko Haram Terrorism) in the country. As such, the study is limited in its generalizability as it involved only few perioperative nurses in Nigeria. A wider coverage study may improve the external validity of the findings.
The working environment of the PON in developed and developing countries might not be comparable. Perioperative nurses in the developed nations may be working under improved working conditions, which is most likely not the case under which PON in most African countries practice. Therefore, PON in Africa, particularly in Nigeria might be at higher risk to operating room hazards compared to those in industrialized countries. It is worthy to note that, this study established high rate of operating room hazards among Nigerian perioperative nurses cutting across all the geopolitical zones of the country. The overall rating of the participants working condition suggests that most of the participants were working in a poor working condition. Hazards and poor working environments have been associated with adverse consequences on the health and performance of staff and on patient safety and most of these hazards in the operating rooms are avoidable. Several educational intervention measures on identifying and preventing different types of hazards not only among perioperative nurses but also for other similar professional groups can significantly reduce the risk of hazards exposures. Furthermore, relevant protective measures should be put in place by the hospital to ensure an optimal working environment for PON so that the employees are able to work under least occupational hazards and work related illnesses. However, additional research is needed to identify and design further measures in reducing the risk of hazards exposures in the OR.
