| Abstract|| |
Context: Radiologists as a group face unique occupational health hazards among which musculoskeletal injuries, chronic eye strain, and others are yet to receive adequate attention. Constant mental strain due to demanding turnaround times and work pressures may lead to burnout and depression. These combine to decrease overall work satisfaction and productivity. Aims: To study the prevalence of various health issues faced by radiologists in India and to assess whether specific demographic and occupational factors are associated with an increased risk. Settings and Design: Cross-sectional observational study conducted as a voluntary anonymous electronic survey. Methods and Materials: A 36-item survey was sent to radiologists through email and social media. All respondents who completed survey were included in the study. Questions regarding workload, repetitive stress injuries, eye strain, burnout, and so on were asked. Statistical Analysis Used: Chi-square test was used to test significance of correlation (P < 0.05). Results: In all, 383 radiologists completed the survey. A high prevalence of repetitive stress injuries, chronic eye strain, depression, and burnout was found. Significant correlation was found between repetitive stress injuries and burnout. Pre-Conception and Pre-Natal Diagnostic Techniques Act (PCPNDT) related issues and work overload were the most common causes of high stress levels. Radiologists whose practices followed ergonomic design showed significantly less prevalence of neck pain. Conclusion: Radiologists in India have a high prevalence of repetitive stress injuries, chronic eye strain, and burnout, along with unique mental stressors such as PCPNDT-related issues.

| Introduction|| |
Radiologists as a group face unique occupational health hazards. Radiology has a singular work environment not seen in other medical specialties. In addition to working long hours on a computer, many radiologists spend ample time performing ultrasound (USG) requiring constant use of a single upper limb resulting in what is called as the Transducer user syndrome. Interventional radiologists working in angiography suites are also exposed to unique musculoskeletal problems. Besides physical issues, the constant mental strain due to the demanding turnaround times and constant work pressures takes its toll as well. These factors contribute to an increased incidence of repetitive musculoskeletal stress injuries, chronic eye strain, and mental health issues such as burnout, stress, depression, and lack of sleep.
Radiation as an occupational health hazard has received adequate attention with multiple national and international guidelines available. However, these nonradiation hazards have probably not yet received the attention they deserve. These can adversely impact the physical and mental health of the radiologist, decrease productivity, increase medical errors, and lead to early burnout. A few previous studies have been published regarding ergonomics and musculoskeletal problems in radiology as well as mental health issues faced by radiologists. However, no previously published study has looked at the overall physical and mental health of radiologists as a whole, as the two are related and often go hand in hand. Also, such a study has not been performed among the Indian radiology community to the best of our knowledge.
A recent editorial in this journal also highlighted the importance of safe ergonomic practices among radiologists to improve their health and productivity. In going with the same theme, we conducted a cross-sectional survey among practising radiologists and radiology residents in India to study the prevalence of various physical and mental health issues faced by them.
| Materials and Methods|| |
The study was designed according to the STROBE checklist for observational studies. A 36-item anonymous voluntary electronic survey was created online using Google Forms (Google Inc., Mountain View, California, USA), including four questions on demographics and practice patterns. This survey was sent to practising radiologists and radiology residents through email and using the social media platform of WhatsApp (2018; WhatsApp Inc., Menlo Park, California, USA). Responses were collected for a 10 day period starting from 4 April 2018 to 14 April 2018. All respondents who completed the survey were included within the study.
Questions regarding film-based versus workstation reporting, volume of work in USG and other modalities, musculoskeletal injuries, varicose veins, chronic eye strain, needle prick injuries, and contraction of tuberculosis were asked. Two questions were asked on ergonomics, whether the respondent was aware of ergonomics in radiology and whether any ergonomic steps had been taken in the respondent's practice to reduce physical injuries. Questions regarding depression, patient abuse, personal satisfaction, recreational activities, exercise, sleep, burnout, and levels and the causes of stress were also included to assess various mental health issues. The responses were statistically analyzed to evaluate for correlation between patient demographics, the presence of various physical and mental health issues, and other issues. Chi-square test was performed to assess the level of significance of correlation. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) software version 20 (IBM Inc., Armonk, New York, USA).
| Results and Analysis|| |
A total of 383 radiologists responded to the survey, of which 67% (258/383) were males and 32% (125/383) females. The radiologists surveyed included a broad mix of radiology trainees along with junior and senior practicing radiologists [Figure 1], with 50% having a work experience of 6 to 20 years. The majority of the respondents (96%; 369/383) practiced purely diagnostic radiology or predominantly diagnostic radiology with few interventional procedures. The working patterns of the radiologists surveyed (predominantly workstation-based vs. predominantly film-based vs. USG-only) are as summarized in [Figure 2]. Most radiologists (74%; 284/383) reported working for 40-70 hours/week [Figure 3]. 15% (59/383) respondents practised tele-radiology, with 81% (48 of 59) practising it for less than 3 hours per day.

As many as 301 of 383 (78%) radiologists reported symptoms consistent with repetitive stress injuries at some point in time after starting their radiology career with the most common being neck pain (52%). The other symptoms are as summarized in [Table 1]. More than one-third (37%; 143/383) of the radiologists did not take any treatment for their repetitive stress injuries [Figure 4]. Neck pain was observed to be significantly more common among female radiologists (P= 0.02). The rest of the repetitive stress injuries did not demonstrate any gender predilection. The prevalence of most repetitive stress injuries predictably increased with years of experience, workload, and number of hours of work per week.

Significant correlation was found between increasing number of USG examinations performed per day and the prevalence of neck pain, low back pain, and shoulder pain (P < 0.05). No significant correlation was found between the number of USG examinations performed and elbow pain, wrist pain, tenosynovitis, and carpal tunnel syndrome.
About 6% of radiologists (23/383) developed varicose veins after joining radiology. 57% of the radiologists (219/383) surveyed said they suffered from symptoms of chronic eye strain and computer vision syndrome (CVS), with the incidence of chronic eye strain significantly increasing with increasing years of experience in radiology (P < 0.05) [Table 2].

32% (124/383) of the respondents had suffered needle prick injuries during their careers in radiology, while one-fourth of all radiologists surveyed (99/383) were not vaccinated against hepatitis B. 9% (35/383) of the respondents had developed tuberculosis after starting their careers in radiology. A majority (57%; 217/383) of radiologists felt their reporting rooms were not adequately aerated or ventilated. However, no significant correlation was found between radiologists acquiring tuberculosis and lack of adequate room ventilation.
45% (173/383) radiologists were not aware of the science of ergonomics, and a majority of respondents (57%; 213/383) either did not know whether ergonomic steps had been taken in their department or reported that no ergonomic steps had been taken. Radiologists in whose practices or departments ergonomic steps had been taken reported a statistically significant lower prevalence of neck pain (P = 0.014).
35% (134/383) of radiologists surveyed reported having an excess workload, and 37% (141/383) reported feeling depressed or having suffered from symptoms of depression at some point in their careers in radiology. The proportion was slightly higher among residents, with 40% saying they suffered from depression; however, the difference was not statistically significant. 46% (178/383) of radiologists reported having faced either physical or verbal abuse from patients in the past. A majority (66%; 255/383) of radiologists reported obtaining either excellent or good personal satisfaction from their work [Figure 5]. However, a high number (40%; 153/383) also felt they were not achieving personal growth in radiology in their current workplace. Only 42% (163/383) of the radiologists said they get adequate time to pursue their hobbies and for recreational activities, and 15% (58/383) reported getting less than 6 hours of sleep every day [Table 3].

The prevalence of burnout among radiologists was 54% (208/383) in our study. A significant correlation was found between the presence of physical repetitive stress injuries and prevalence of burnout (P < 0.05). Significant correlation was also found between radiologist burnout and past patient abuse, depression, lack of time for hobbies and recreation, less than 6 hours of sleep, and lack of personal work satisfaction (P < 0.05). A significant correlation was also found between the prevalence of burnout and radiologists who reported lack of proficiency in management skills (P < 0.05).
On a scale of 1 to 10 to measure levels of stress with 1 being the least and 10 being the maximum possible level of stress, 53% (205/383) of the radiologists reported a stress level of 7 to 10 [Figure 6]. Generally, those radiologists reporting burnout, depression, patient abuse, lack of personal work satisfaction, and improper workplace relationships had higher levels of stress. Among the causes of stress mentioned, the most common cause of stress among radiologists was Pre-Conception and Pre-natal Diagnostic Techniques Act (PCPNDT) related issues (53%; 203/383) and work overload (50%; 193/383). Inadequate income was also cited as a source of stress by 36% (139/383) respondents, with other causes of stress being administrative responsibilities (29%; 110/383) and improper workplace atmosphere and interpersonal relationships (27%; 103/383) [Table 4].

27% (105/383) of the radiologists surveyed felt lack of proficiency in their communication skills, and 41% (159/383) radiologists did not feel proficient in their management skills.
Despite the high prevalence of repetitive stress injuries, depression, and burnout among radiologists in India, a majority (58%; 223/383) did not actively exercise, meditate, or play sports [Table 3]. Radiologists who regularly either exercised or meditated or played sports had a statistically significant low prevalence of burnout as compared to those who did not (P = 0.01).
| Discussion|| |
The incidence of musculoskeletal injuries among Indian radiologists reported in our study was much higher than those reported in western literature, with some injuries having almost double the incidence. The prevalence of musculoskeletal injuries among radiologists in our study versus another 2018 study from the United States in JACR is as follows – neck pain: 52% in our study versus 25% in the JACR study, low back pain: 45% in our study versus 32% in the JACR study, and 78% prevalence of at least one upper limb joint repetitive stress injury in our study versus 16% with an upper limb stress injury in the JACR study.
A significant correlation was found in our study between increasing USG workload and prevalence of neck pain, low back pain, and shoulder pain – a condition known as Transducer user syndrome. The incidence matched with those of studies on sonologists published elsewhere (65%–78%). Radiologists perform a lot of visual (convergence and accommodation) exercise during work, leading to ciliary muscle fatigue and sometimes ciliary muscle spasm. This leads to digital eye strain and CVS. Symptoms of CVS include headache, blurred vision, either dry eyes or excessive watering from eyes, eye strain, and diplopia.
Various studies indicate a prevalence of CVS ranging from 68% to 76% among computer professionals in India and other South Asian countries., Our study also showed a prevalence of 57% for eye strain among radiologists.
Ergonomics (from ergo: work and nomo: natural law) is the science of designing workplaces, products and systems so that they fit the people who use them. Use of ergonomic chairs, ergonomic workstations, and imparting ergonomic training have been reported to cause up to a 70%–80% of improvement in repetitive stress symptoms. In our study, radiologists in whose practices or departments ergonomic steps had been taken reported a statistically significant lower prevalence of neck pain (P = 0.014).
As per World Health Organization estimates, the lifetime prevalence of mental illnesses in the general population is an astonishingly high number of 18%–36%., Approximately 13%–20% of physicians are known to suffer from depression., In our study, 37% of radiologists reported feeling depressed at some point in their careers.
Burnout is increasingly being recognized as a serious mental health condition. It has been defined as a triad of emotional exhaustion, depersonalization, and reduced personal accomplishment., Residency in particular is known to be a period of one's career where one is prone to develop a psychiatric illness. As per previous studies, one-third of residents suffer from depression and up to 75% residents experience burnout., In our study, 40% of residents reported feeling depressed at some point in their radiology career, and 55% reported burnout. Importantly, a 1996 report in Lancet found burnout to be significantly higher in radiologists as compared to nonradiologists (which included surgeons, oncologists, and gastroenterologists), indicating the need to focus more on this issue within the radiology community.
A unique stressor among Indian radiologists, which is also the most common cause of stress among them, is PCPNDT-related issues [Table 4]. Our study showed 66% of radiologists reporting either excellent or good sense of personal satisfaction from their work [Figure 5]. This number is much less when compared with previous studies from the United States and Europe which have reported more than 90% of radiologists with very high or somewhat high levels of personal satisfaction.,,,
Limitations of our study include the use of a voluntary subjective electronic survey to collect responses, with its inherent biases. Standardized questionnaires to test for burnout are available, the most commonly used being the Maslach Burnout Inventory. Our study does not test for burnout using Maslach Inventory questionnaire, and a subjective question regarding whether the responder has experienced burnout at any time during his or her career in radiology had been asked instead. Further more detailed studies on radiologists in India should be carried out using standardized psychological questionnaires to investigate this serious issue further.
| Conclusion|| |
Radiologists in India show a higher prevalence of repetitive stress injuries, chronic eye strain, and burnout as compared to their western counterparts. Indian radiologists are also faced with unique mental stressors with the most common being PCPNDT-related issues, and overall report less work satisfaction when compared with the West. Significant correlation exists between the presence of repetitive stress injuries and burnout among radiologists.
