Association of overtime work and obesity with needle stick and sharp injuries in medical practice

BACKGROUND Needle stick and sharps injuries(NSIs)may cause infections among medical personnel.Obesity and overtime work among medical personnel increase the incidence of work injuries.AIM To investigate whether overtime work and obesity increase the risk of NSIs.METHODS This cross-sectional study used the data of 847 hospital personnel,including 104 doctors,613 nurses,67 medical laboratory scientists,54 specialist technicians,and nine surgical assistants.Of them,29 participants notified the hospital of having at least one NSI in 2017.The data collected included age,overtime work,body mass index,medical specialty such as doctor or nurse,and professional grade such as attending physician or resident.Theχ2 and Fisher’s exact tests were used to compare categorical variables.Multiple logistic regression analysis and the Sobel test were used to assess the risk of NSIs.RESULTS Overtime work,body weight,and medical specialty were significantly associated with NSIs(P<0.05).After adjustment for risk factors,heavy overtime work was an independent risk factor for NSIs,and healthy body weight and nursing specialty were independent protective factors against NSIs.After adjustment for risk factors,medical personnel with healthy body weight has half as many NSIs as those with unhealthy body weight;the proportion of NSIs in doctors with healthy body weight was 0.2 times that in doctors with unhealthy body weight;the proportion of injuries among residents was 17.3 times higher than that among attending physicians;the proportion of injuries among junior nurses was 3.9 times higher than that among experienced nurses;the proportion of injuries among nurses with heavy overtime work was 6.6 times higher than that among nurses with mild overtime work;and the proportion of injuries among residents was 19.5 times higher than that among junior nurses.Heavy overtime work mediated the association of medical specialty with NSIs.CONCLUSION In addition to promoting the use of safety needles and providing infection control education,managers should review overtime schedules,and medical personnel should be encouraged to maintain a healthy weight.

Effect of overtime pancreaticoduodenectomy on the short-term prognosis of patients

BACKGROUND Due to the large number of operations,surgeons sometimes need to work overtime or even stay up late to perform pancreaticoduodenectomy.Fatigue and sleep deprivation can result in an increased error rate at work.There have been numerous studies about the effect of overtime surgery on the prognosis of patients.However,the effect of overtime work for pancreaticoduodenectomy on the prognosis of patients is unclear.This study explores the impact of overtime work for pancreaticoduodenectomy on the prognosis of patients.AIM To explore the impact of overtime work for pancreaticoduodenectomy on the short-term prognosis of patients.METHODS This was a single-center,retrospective cohort study.The patients who underwent pancreaticoduodenectomy between January 2017 and December 2019 were included.Patients were stratified by operative start time into the control group(surgery that started between 8:00 and 16:49)and the overtime group(surgery that started between 17:00 and 22:00)and compared intraoperative and postoperative parameters.The following parameters were compared between the overtime group and the control group:Operative time,blood loss,number of lymph nodes removed,duration of treatment in the Intensive Care Unit(ICU),and incidence of complications.RESULTS From January 2017 to December 2019,a total of 239 patients underwent pancreaticoduodenectomy in the Department of Hepatobiliary Surgery of our institution.Four patients were excluded from this study due to lack of clinical data.A total of 235 patients were included,with 177 in the control group and 58 in the overtime group.There was no difference between the two groups in operative time,blood loss,number of lymph nodes removed,ICU length of stay,hospital length of stay,mortality during hospitalization.Compared with the control group,the overtime group had a higher incidence of pancreatic fistula(32.8%vs 15.8%,P<0.05).Multivariate analysis showed that overtime work,higher Body Mass Index were independent risk factors for pancreatic fistula(P<0.05).CONCLUSION Overtime work for pancreaticoduodenectomy increases the incidence of pancreatic fistula.The effect of overtime surgery on the long-term prognosis of patients’needs to be further studied.

Mathematical Models to Simultaneously Determine Overtime Requirements and Schedule Cells

The problem studied in this paper was inspired from an actual textile company. The problem is more complex than usual scheduling problems in that we compute overtime requirements and make scheduling decisions simultaneously. Since having tardy jobs is not desirable, we allow overtime to minimize the number of tardy jobs. The overall objective is to maximize profits. We present various mathematical models to solve this problem. Each mathematical model reflects different overtime workforce hiring practices. An experimentation has been carried out using eight different data sets from the samples of real data collected in the above mentioned textile company. Mathematical Model 2 was the best mathematical model with respect to both profit and execution time. This model considered partial overtime periods and also allowed different overtime periods on cells. We could solve problems up to 90 jobs per period. This was much more than what the mentioned textile company had to handle on a weekly basis. As a result, these models can be used to make these decisions in many industrial settings.

Climate change is the first real challenge of this global generation,and,so far,it hasn’t gone that well.Whether it’s rising sea levels threatening cities like Shanghai or expanding vectors of malaria,China must change with the climate.As the glaciers of China’s Third Pole retreat,as new and more regular floods attack first-tier cities and rural towns alike,as wheat yields decrease in the north and entire lakes dry up in the west,the days of ignoring climate change have

Is burnout a mediating factor between sharps injury and workrelated factors or musculoskeletal pain?

BACKGROUND Burnout,musculoskeletal pain,and sharps injuries(SIs)affect medical workers.AIM To establish a model between SIs,burnout,and the risk factors to assess the extent to which burnout affects SIs.METHODS This questionnaire was used for an observational and cross-sectional study,which was based on members at a hospital affiliated with a medical university in Taichung,Taiwan,in 2020.The valid responses constituted 68.5%(1734 of 2531).The items were drawn from the Nordic Musculoskeletal Questionnaire and Copenhagen burnout inventory and concerned work experience,occupational category,presence of chronic diseases,sleep duration,overtime work,and work schedule.Factor analysis,chi-square test,Fisher exact test,Multiple linear,logistic regression and Sobel test were conducted.The present analyses were performed using SAS Enterprise Guide 6.1 software(SAS Institute Inc.,Cary,NC,United States),and significance was set at P<0.05.RESULTS Personal and work-related burnout ranks, sex, work experience ranks, occupationalgroups, drinking in the past month, sleep duration per day, presence ofchronic diseases, overtime work ranks, and work schedule were associated withSIs. Frequent upper limb and lower limb pain (pain occurring every day or once aweek) determined to be related to SIs. High personal burnout (> Q3) and highwork-related burnout (> Q3) mediated the relationship between SIs and frequentlower limb pain. Similarly, frequent lower limb pain mediated the relationship ofSIs with high personal and high work-related burnout. High personal and highwork-related burnout mediated the relationships of SIs with overtime work andirregular shift work. The mediating model provides strong evidence of anassociation between mental health and SIs.CONCLUSIONBurnout was determined to contribute to SIs occurrence;specifically, it mediatedthe relationships of SIs with frequent musculoskeletal pain, overtime work, andirregular shift work.

Schedule Compression Impact on Construction Project Safety

Many construction projects are met with stringent timelines or the threat of exorbitant liquidated damages. In addition, construction schedulers are frequently forced to incorporate aggressive schedule compression techniques. As already discussed by previous researchers, these schedule compression techniques have direct impacts on project productivity and quality defects.Researchers have also pointed out that schedule compression will affect safety incidents such as Occupational Safety & Health Administration recordable injuries and near misses over long project durations. However, most of the existing studies treated safety as a subcategory of project productivity and project quality, and minimal research has been done to directly quantify the effect of schedule compression on safety at the project level.Therefore, in this research, we conducted a survey and statistical analysis to investigate the relationship between schedule compression and safety in construction projects.We interviewed various members of the Houston construction community from both industrial and non-industrial roles. Statistical analysis was used to identify factors that have significant impacts on the occurrence of safety incidents at an industry specific level.
