According to National Institute for Occupational Safety and Health (NIOSH), healthcare providers are facing expanding numbers of occupational hazards including wounds and ailments, with rates having increased significantly during the previous decade (2). It has been assessed by the International Labour Organization (ILO) that 160 million people in the world suffer from occupation-related illnesses such as musculoskeletal diseases and psychiatric problems. Meanwhile, 270 million lethal and non- lethal work-related accidents resulted in more than 350, 000 victims and over two million work-related deaths each year were reported and indorsed to occupational hazards (3). 1Corresponding author E-mail: tavga.aziz@univsul.edu.iq Received: 6/11/2020 Accepted:14 / 1/2021 Published Online First: 2021-12-09 Iraqi Journal of Pharmaceutical Science https://doi.org/10.31351/vol30iss2pp41-49 mailto:aziz@univsul.edu.iq Occupational hazards facing healthcare providers Iraqi J Pharm Sci, Vol.30(2) 2021 42 ealthcare providers are exposed to a wide range of work related hazards; these include biological and non-biological hazards. Biological hazards refer to organisms or organic matters produced by these organisms that are harmful to human health. These include parasites, viruses, bacteria, fungi and protein. Generally, there are three major routes of entry for these micro- organisms into our body, i.e. through the respiratory system, transmission through contact with body fluids of the infected person or contact with contaminated objects(4). Regarding non-biological hazards it includes chemical, physical, psychological hazards, noise, stress and others (5). Only few hospitals have sorted out extensive work related surveillance frameworks and most of these hospitals do not have a definitive plan. Hospitals incorporate various "mini-industries" inside their partitions, and health workers regularly move from one department to another during their shift. The threats mainly come from exposure to chemicals, radioactive substances, infectious agents, mechanical agents, latex, violence, and mental, psychosocial, and physical stressors (6, 7). A few of these threats have been managed, for instance exposure to blood borne pathogens, ethylene oxide, and formaldehyde. Substances such as glutaraldehyde and hazardous drugs are not being addressed as biohazards however, it represent a danger to the workers wellbeing. In addition to managed substances and those regulated by NIOSH and different agencies, risks specifically to health workers incorporate exposures to natural rubber latex, infectious diseases, anesthetic gases, ergonomic stressors, hazardous drugs, and psychological, psychosocial, and physical stress. Health care-specific hazards must be considered while developing a surveillance program for healthcare workers (8). There are only a few existing researches focusing on the wellbeing of workers in the healthcare settings. Studies that have concentrated on worker’s injury in healthcare facilities recommend that poorly controlled work environment and high workloads are directly correlated with the increments in health care worker’s injuries, including needle stick wounds and near-misses to medical nurses (8,9). Another important point is that till now most of the studies focused on patient safety-related outcomes and sets procedures to improve patient safety, without paying attention to the hazards that faces health workers daily during performing their work (10,11). Some reports on patient-related adverse events and patients mortality showed that hospitals with better safety climate overall had lower relative incidence of adverse events in hospitals (12,13).Accordingly, the present study was designed to shed a light on the daily occupational hazards that face healthcare providers while performing their work. Study Design and Setting This cross-sectional study utilized quantitative data collection methods. It was carried out in Sulaimani city, Kurdistan region, Iraq. The study was conducted between November 2019 and February 2020. The study protocol was approved by the Research Ethics Committee of the College of Pharmacy, University of Sulaimani (certificate no.(1) in September 3, 2018), in accordance with the Declaration of Helsinki revised in 2000. Sampling Eight major hospitals were targeted during the study. These were purposively selected based on size and patient capacity. The selection ensured a combination of governmental and private facilities. These included Sulaimani Teaching Hospital, Shar Hospital, Central Laboratory, Sarwari Healthcare Center, Piramerd Dental Center, Pediatrics Teaching Hospital and Shorsh Hospital as public facilities in addition to some of private clinics and laboratories. Study population The study population comprised a range of healthcare workers working in the selected health facilities. To select the respondents, sampling proportionate to size was used to determine the number of healthcare workers to be interviewed from each hospital. At the hospital, all healthcare workers who were presented at the facility were considered. Among 200 healthcare workers interviewed, one hundred and fifty nine (159) responded. The selection was made according to their occupation in the healthcare facility, and they were categorized into five groups as follow: (a) Physicians (b) Pharmacists (c) Medical assistants (d) Laboratory Instructors and (e) Nurses. Data Collection All participants were interviewed by the researchers using a structural questionnaire designed and validated for this study (Appendix I). It included demographic data, duration of exposure, use of personal protective equipment (PPE), health status, and working condition; and whether they have been trained to protect themselves against different types of work place-related health hazards. Consensual agreement is signed by the subjects at the end of each questionnaire. Each interview consumed approximately 35–45 minutes.

There are limited studies that focus on the safe environment in the workplace. Research that have concentrated on healthcare employee injury outcomes endorse that bad organizational status and high workloads are associated with increased injuries, including needle stick injuries and near- misses to practicing nurses.15 Additionally, most of the efforts on hospital and healthcare safety climate to date are patient oriented rather than employee oriented. These studies focused mainly on patient safety-related strategies to improve patient safety rather than employee safety. Previous studies investigating medical institution and healthcare safety state exhibit fewer patient-associated injury events and mortality associated with superior work place protection climates 16,12. In the current study, health care providers who have participated in training courses on the safety and hazards exposure were less exposed to biological hazards yet statistically non-significant. A study conducted by Sarbaz et al. concluded that training had a remarkable effect and reported substantial decrease in the number of exposure events 17. The present study revealed that the majority of respondents had experienced both types of hazards. Lab instructors were the most exposed category and the least were the pharmacists; these findings were highly comparable with those reported in other studies that reported women are the majority of health care providers, exposed to risks of different types of hazards like infection, violence, musculoskeletal injuries 5,16. In the current study, the nurses were the most healthcare personnel who follow the safety control measures, through taking training courses on hazards and work safety while the pharmacists are the least in this respect. Meanwhile, taking necessary vaccinations was mostly reported in the physicians and least among pharmacists. Regarding the periodic follow up examinations, they are mostly observed among lab instructors and the least among pharmacists. Additionally, the presence of preventive or risk control measures in the place of work was mostly accessible by the nurses and least by the pharmacists. Healthcare protection when facing injuries are mostly reported by the medical assistants and least by pharmacists. An interesting finding in our study is that healthcare providers who had taken the necessary vaccines related to their occupation were significantly less exposed to blood Occupational hazards facing healthcare providers Iraqi J Pharm Sci, Vol.30(2) 2021 48 borne diseases with no significant changes in infectious diseases and air borne diseases, compared to those who did not take the suitable vaccinations. Nurses were found to be more prone to sharp related injuries and cut/wound in the hospitals compared to other professionals; this can be attributed to the nature of their work and handling of sharp equipment when practicing their job. Similar finding was reported by Ilhan et al. who claimed that the percentage of nurses facing a sharp or needle stick injury during their professional life was high (18). The present study also showed that lab instructors are more exposed to contact with contaminated specimens/biohazards and air borne diseases, which may be due to the fact that they are dealing with the biological specimens in public and private health sectors during practicing their daily work. Unsafe disposal of medical wastes is a major challenge in developing countries as they contributes largely to occupational injuries and infections (19, 20). Additionally, in the present study, other hazards such as psychological, chemical spills and fall although are uncommon at healthcare settings (5), but lab instructors are still relatively more prone to such types of hazards 21. Lab instructors, nurses, medical assistants, physicians, and pharmacists are exposed to the risks of noise, in descending order. Furthermore, medical assistants are most at risk of radiation in the work place due to dealing with radiating machinery at the hospitals. Regarding the risks of exposure to infectious disease, physicians are on the top of the list, since they are more prone to acquire infections among other healthcare providers that mainly resulted from their close contact with infected patients in both public and private clinics (22). Moreover, physicians are also the most exposed group to stressful conditions compared to others and the study reported two cases of fractures which could be probably due to their hard duty in the hospital and the necessity to make critical decisions on a daily basis. Other studies showed that long work hours of physicians increase the incidence of stress and depression (23,5). Study Limitations The main limitation of this study is the small sample size and the results could have been affected by recall bias as respondents were required to recall past experience. Conclusion Healthcare providers in healthcare settings of Sulaimani city experience several hazards in their workplaces. Occupational hazards became a dominant issue among health care providers, since they get exposed to a wide variety of hazards ranging from biological, chemical, physical, to psychosocial hazards. Interventions should be established to alleviate these hazards. Training courses on the risk of health hazards and safety measures suggested mitigating these hazards. References 1.
