Occupation-associated health hazards for the gastroenterologist/endoscopist

An estimation of the endoscopist's musculoskeletal injury risk for right and left lateral decubitus positions during colonoscopy: a field-based ergonomic study

BACKGROUND

Colonoscopy exposes endoscopists to awkward postures and prolonged forces, which increases their risk of musculoskeletal injury. Patient positioning has a significant impact on the ergonomics of colonoscopy. Recent trials have found the right lateral decubitus position is associated with quicker insertion, higher adenoma detection rates, and greater patient comfort compared to the left lateral decubitus position. However, this patient position is perceived as more strenuous by endoscopists.

METHODS

Nineteen endoscopists were observed performing colonoscopies during a series of four-hour endoscopy clinics. Durations of each patient position (right lateral decubitus, left lateral decubitus, prone, and supine) were recorded for all observed procedures (n = 64). Endoscopist injury risk was estimated by a trained researcher for the first and last colonoscopies of the shifts (n = 34) using Rapid Upper Limb Assessment (RULA), an observational ergonomic tool that estimates risk of musculoskeletal injury by scoring postures of the upper body and factors such as muscle use, force, and load. The total RULA scores were compared with a Wilcoxon Signed-Rank test for patient position (right and left lateral decubitus) and time (first and last procedures) with significance taken at p < 0.05. Endoscopist preferences were also surveyed.

RESULTS

The right lateral decubitus position was associated with significantly higher RULA scores than the left lateral decubitus position (median 5 vs. 3, p < 0.001). RULA scores were not significantly different between the first and last procedures of the shifts (median 5 vs. 5, p = 0.816). 89% of endoscopists preferred the left lateral decubitus position, primarily due to superior ergonomics and comfort.

CONCLUSION

RULA scores indicate an increased risk of musculoskeletal injury in both patient positions, with greater risk in the right lateral decubitus position.

Musculoskeletal injury and ergonomics in pediatric gastrointestinal endoscopic practice

BACKGROUND AND AIMS

Endoscopy-related musculoskeletal injuries (ERI) are increasingly prevalent in adult endoscopists; however, there are no studies that have evaluated ERI and ergonomic practices among pediatric gastroenterologists and trainees. We aimed to examine the prevalence, nature, and impact of musculoskeletal injuries in pediatric endoscopic practice and assess attitudes towards ergonomic training needs.

METHODS

Pediatric gastroenterologists and trainees were surveyed to collect information on endoscopist and practice characteristics, the prevalence, nature, and impacts of ERI, ergonomics strategies employed in practice, previous ergonomics training, and perceptions of ergonomics training (elicited using a 1 (strongly disagree) to 5 (strongly agree) Likert scale). Responses were analyzed using descriptive statistics, and bivariate analyses were conducted to explore correlates of ERI.

RESULTS

Among 146 survey respondents, 50 (34.2%) were trainees and 96 (65.8%) were practicing endoscopists with a mean duration of endoscopic practice of 9.7 ± 9.4 years. Overall, 55.6% (n = 80/144) reported experiencing a musculoskeletal injury, with 34.7% (n = 50/144) reporting an injury attributable to endoscopy. Among those with ERI, the most common sites were the neck/upper back (44.0%), thumb (42.0%), hand/finger (38.0%), and lower back (36.0%). Women were more likely to experience ERI compared to men (43.4% vs. 23.4%; p = 0.013). Only 20.9% of participants had formal training in ergonomics. Respondents reported being motivated to implement practice changes to prevent ERI (4.41 ± 0.95) and perceived ergonomics training as important (4.37 ± 0.96).

CONCLUSIONS

Pediatric endoscopists, and particularly women, experience significant ERI; however, formal endoscopy ergonomics training is rare. Improved ergonomics training is needed for both practicing pediatric gastroenterologists and trainees.

Ergonomics of gastrointestinal endoscopies: Musculoskeletal injury among endoscopy physicians, nurses, and technicians

BACKGROUND

Musculoskeletal injuries (MSI) have plagued endoscopists and ancillary staff for decades without any innovative and strong ergonomic guidelines. It has placed a physical and mental strain on our endoscopists and ancillary staff. We have very have limited data supporting this claim in our region and most data is supported by western literature.

AIM

To document the prevalence of MSI, and awareness and practices of ergonomics by endoscopists and ancillary staff.

METHODS

This is an observational cross-sectional study, conducted in Karachi, a city that boasts the maximum number of daily endoscopies in the country. An eleven-point self-administered questionnaire was distributed and used to evaluate MSI and ergonomic adjustments amongst three tertiary care setups in Karachi. An onsite survey via a 13-point checklist for endoscopy suite facilities was used to assess the ergonomically friendly conveniences at five tertiary care setups in Karachi. A total of 56 participants replied with a filled survey.

RESULTS

There were 56 participants in total with 39 (69.6%) males. Pain and numbness were documented by 75% of the patients, with pain in the neck (41.1%), lower back (32.1%), shoulder (21.4%), thumb (12.5%), hand (23.2%), elbow (8.9%), and carpal tunnel syndrome (CTS) (7.1%). Of those, 33.3% attributed their symptoms to endoscopy, 14.2% said that symptoms were not caused by endoscopy, and 52.4% were not certain whether endoscopy had caused their symptoms. Twenty-one point four percent of patients had to take time off their work, while 33.9% took medications for pain. Ergonomic modifications to prevent musculoskeletal injury, including placement of endoscopic monitor at eye level and the cardiac monitor in front, stopping the procedure to move patients, sitting while performing colonoscopy, and navigating height-adjustable bed were used by 21.4%. Nine out of 13 ergonomic facilities were not present in all five tertiary care hospitals. Conveniences, such as anti-fatigue mats, height-adjustable computer stations, and time out between patients were not present.

CONCLUSION

Three-fourth of our endoscopists reported MSI, of which more than half were not sure or attributed this problem to endoscopy. The prevalence of MSI warrants urgent attention.

Socioeconomic status and ADL disability of the older adults: Cumulative health effects, social outcomes and impact mechanisms

INTRODUCTION

Socioeconomic status (SES) is one of the important indicators affecting individual's social participation and resource allocation, and it also plays an important role in the health shock of individuals. Faced by the trend of aging society, more and more nations across the world began to pay attention to prevent the risk of health shock of old adults.

METHODS

Based on the data of China Health and Retirement Longitudinal Study (CHARLS) in 2013, 2015 and 2018, this study uses path analysis and ologit model to empirically estimate the effects of SES and health shock on the activities of daily living (ADL) disability of old adults.

RESULTS

As a result, first, it was found that SES has significant impact on the disability of old adults. Specifically, economic conditions (income) plays dominant role. Economic status affects the risk of individual disability mainly through life security and health behavior. Secondly, SES significantly affecting health shock, with education and economic status showing remarkable impact, and there is an apparent group inequality. Furthermore, taking high education group as reference, the probability of good sight or hearing ability of the low education group was only 49.76% and 63.29% of the high education group, respectively, while the rates of no pain and severe illness were 155.50% and 54.69% of the high education group. At last, the estimation of path effect of SES on ADL disability indicates evident group inequality, with health shock plays critical mediating role.

CONCLUSIONS

SES is an important factor influencing residents' health shock, and health shocks like cerebral thrombosis and cerebral hemorrhage will indirectly lead to the risk of individual ADL disability. Furthermore, among the multi-dimensional indicators of SES, individual income and education are predominant factors affecting health shock and ADL disability, while occupation of pre-retirement have little impact.

Smaller hands and less experience are associated with greater ergonomic strain during endoscopic procedures

INTRODUCTION

Up to 89% of physicians who routinely perform endoscopy experience some type of musculoskeletal pain. In this study, we sought to quantitatively analyze provider factors that influence ergonomic strain during live endoscopic procedures.

METHODS

Surface electromyography (sEMG) was used to measure ergonomic strain on physicians while performing upper and lower endoscopies. EMG data were normalized to a maximal voluntary contraction (MVC) recording for each muscle group, yielding a %MVC value. Subgroup analyses were performed based on glove size, physician training level, specialty, and handedness.

RESULTS

A total of 165 upper (n = 68) and lower (n = 97) endoscopies were recorded. Endoscopists with small hand sizes had significantly higher ergonomic strain in the left anterior and posterior forearm muscle compartments as compared to endoscopists with medium or large hands (%MVC L-anterior: small: 9.1 ± 1.1; medium: 6.4 ± 1.2; large: 5.9 ± 1.6; p < 0.001); (%MVC L-posterior: small: 12.0 ± 0.8; medium: 9.4 ± 1.3; large: 8.8 ± 1.4; p < 0.001). Additionally, upper body muscle groups had significantly higher ergonomic strain in endoscopists with less lifetime endoscopic experience (%MVC R-trapezius: expert: 8.4 ± 1.2; novice: 9.3 ± 1.2; p < 0.05); (%MVC R-deltoid: expert: 6.1 ± 1.4; novice: 8.5 ± 1.3; p < 0.001). There were no significant ergonomic differences between surgeons or gastroenterologists and no differences between right- and left-handed dominant individuals.

CONCLUSIONS

Endoscopists with small hands experienced great ergonomic strain in their left forearm. Our data support the widely held belief that "one size does not fit all" and will hopefully spark change in the design of future endoscopes by device manufacturers. Our data also support that the experience level of the endoscopist contributed significantly to ergonomic performance, likely due to postural differences leading to decreased upper body strain. Therefore, it remains critically important to educate young proceduralists on strategies for ergonomic relief early in his or her endoscopic training program that can ameliorate ergonomic strain that accrues over the lifetime of a physician's career.

Colonoscopy-related injury among colonoscopists: an international survey

Background and study aims  Colonoscopy is physically demanding for endoscopists and patients. Repetitive movements during colonoscopy can lead to overuse injuries. We aimed to explore the prevalence and range of colonoscopy-related musculoskeletal injuries (CRIs) in endoscopists. Methods  A cross-sectional electronic survey of 1825 endoscopists was performed. The sample was composed of members of the British Society of Gastroenterology, European Society of Gastrointestinal Endoscopy, and National Nurse Endoscopy Group (UK). The survey comprised 20 questions. These included: endoscopists' workload, level of experience, and their perceived CRIs. All endoscopists who perform colonoscopy independently were included in the analysis. Results  A total of 368 questionnaires were completed of 1825 surveyed (20.16 %). Of those, 319 participants (17.48 %) were fully independent in colonoscopy. Of 319 endoscopists, 254 (79.6 %) have experienced musculoskeletal injuries. These were reported as either possibly (n = 143, 56.3 %) or definitely (n = 90, 35.4 %) related to colonoscopy. Commonly injured areas were the lower back (n = 85, 36.5 %), neck (n = 82, 35.2 %) and left thumb (n = 79, 33.9 %). Of the injured endoscopists, 98 (30.7 %) made some modification to their practice, such as stretching exercises and ergonomic changes. Of the endoscopists, 134 (42.0 %) thought that repetitive limb strain was a likely causative mechanism. Around 40 % believed that torquing the scope and challenging body position were precipitating CRIs. Several treatment modalities were used to treat CRIs. These included; physiotherapy (n = 109), medications (n = 70), rest (n = 43), splinting (n = 31), steroid injections (n = 26) and surgery (n = 11). Conclusions  A significant proportion of colonoscopists experience CRIs. The majority of the suggested modifications to practice can be adopted by any endoscopist. These results highlight the need to recognise CRI as an important occupational health hazard and to adopt preventative strategies routinely in the future.

Bilio-pancreatic endoscopy during COVID-19 pandemic

On 31 December 2019, the WHO China Country Office was informed of cases of pneumonia of unknown etiology detected in Wuhan (Hubei Province of China). In January 2020, a new coronavirus named SARS-CoV2 was isolated and, since that time, SARS-CoV2 related disease (COVID-19) rapidly spread all over the world becoming pandemic in March 2020. The COVID-19 outbreak dramatically affected the public-health and the health-care facilities organization. Bilio-pancreatic endoscopy is considered a high-risk procedure for cross-contamination and, even though it is not directly involved in COVID-19 diagnosis and management, its reorganization is crucial to guarantee high standards of care minimizing the risk of SARS-CoV2 transmission among patients and health-care providers. Bilio-pancreatic endoscopic procedures often require a short physical distance between the endoscopist and the patient for a long period of time, a frequent exchange of devices, the involvement of a large number of personnel, the use of complex endoscopes difficult to reprocess. On this basis, endoscopic units should take precautions with adjusted management of bilio-pancreatic endoscopy. The aim of this article is to discuss the approach to bilio-pancreatic endoscopy in the COVID-19 era with focus on diagnostic algorithms, indications, management of the endoscopic room, proper use of Personal Protective Equipment and correct reprocessing of instrumentation.

Work-Life Conflict and Its Health Effects on Korean Gastroenterologists According to Age and Sex

BACKGROUND

This study aimed to evaluate the work-life pattern and prevalence of occupation-related symptoms, as well as the effect of work-life balance on health status according to age and sex among Korean gastroenterologists.

METHODS

A total of 222 gastroenterologists from 44 nationwide centers in South Korea participated in an anonymized self-responded electronic questionnaire survey about their daily activities and symptoms for 14 days. Musculoskeletal, gastrointestinal and mental symptoms were scored using a numerical scale. The Maslach Burnout Inventory was used to measure the burnout score.

RESULTS

Korean gastroenterologists (124 men and 98 women) spent 71.5 ± 19.0 h/week for work (54.0 ± 16.2 in-hospital and 17.5 ± 9.5 out-of-hospital), without any differences regarding sex. However, women spent more time performing housework and parenting (20.7 ± 19.0) compared to men (14.3 ± 13.3, P = 0.007). Musculoskeletal pain was found in 199 respondents (89.6%), and women had a higher total pain score compared to men in all age groups (P = 0.016). Gastrointestinal and mental symptoms were found in 119 (53.6%) and 153 (68.9%), respectively. Work-life ratio was significantly correlated with musculoskeletal (P < 0.001), gastrointestinal (P = 0.048) and mental symptoms (P = 0.003). Using the Maslach Burnout Inventory, 64.4% of the respondents demonstrated burnout. Moreover, emotional exhaustion, depersonalization and personal accomplishment scores were worst in women in their 30s or 40s.

CONCLUSION

Korean gastroenterologists suffered from musculoskeletal, gastrointestinal and mental symptoms and were highly prone to burnout due to long and laboring work. Work-life imbalance and burnout were most severe in young women doctors due to their domestic demands.
