Burnout and patient care in junior doctors in Mexico City

Background Burnout is known to occur in public service workersleading to a reduction in effectiveness at work. Aim To estimate the prevalence of burnout in junior doctorsand its impact on patient care. Methods A cross-sectional study of junior doctors at three hospitalsin Mexico City was conducted. Measures used included the MaslachBurnout Inventory (MBI), measuring depersonalization (DP), emotionalexhaustion (EE) and personal achievement (PA), a questionnaireabout patient care practices and attitudes and one on sociodemographiccharacteristics. Logistic regression analysis was used to assessthe association between burnout and suspected risk factors. Results A total of 312 junior doctors participated (responserate 65%). In total, 57% were male and the average age was 28.Average scores in MBI subscales were EE: 18.2, DP: 6.9 and PA:37.6. Burnout prevalence was 40% (126). Junior doctors withburnout were more likely to report suboptimal patient care practicesoccurring monthly (OR 5.5; 95% CI 2.7–11.2) and weekly(OR 5.2; 95% CI 1.6–16.3). The logistic regression modelfor burnout included shifts lasting >12 h, current depression,former major depression, first- or second-year junior doctors,male gender and single status. Conclusions Burnout was most strongly associated with shifts>12 h and with both current and previous depression. Reportedsuboptimal patient care was also associated with working shiftsof 12 h. Burnout may be adversely affecting junior doctors’health and their patients’ care.     

Piecework, musculoskeletal pain and the impact of workplace psychosocial factors

Aim To investigate the impact of piecework on musculoskeletalpain and general health, and the influence of perceived workplacepsychosocial factors on any such associations, in a generalUK population. Methods A questionnaire was mailed to an age-stratified randomsample of 10 000 adults aged 18–75 in North Staffordshire,UK. Respondents reporting a current main job were asked if thisjob was paid by a piecework system. Health measures were (i)number of pain areas according to a body manikin and (ii) generalhealth (SF-12v2). Other measures included questions on occupationalhistory and psychosocial aspects of the work environment. Results The adjusted response was 54%. A total of 1193 respondentsreported a current main job, of whom 201 (17%) reported piecework.Pieceworkers were more likely to be older (P < 0.05), male(P < 0.001) and in lower socioeconomic groups (P < 0.001)than non-pieceworkers. Piecework was associated with perceptionsof a poor psychosocial working environment, more pain areas(P < 0.05), more elbow (P < 0.01), forearm (P < 0.001)and hand pain (P < 0.05), and a lower physical health score(SF-12v2; P < 0.01), but no difference in mental health score(P = 0.60), compared with non-pieceworkers. After controllingfor psychosocial factors, and socioeconomic group, the associationsbetween piecework and pain areas, or physical health, were nolonger statistically significant. Conclusions These results show that piecework was associatedwith poorer self-reported general physical health and more areasof pain, which may be attributed to low socioeconomic group,and workplace perceptions of little job control, high physicaldemand and little supervisor support.     

The impact of the COSHH regulations on workers with occupational asthma

In the UK, the COSHH Regulations give specific guidance thatemployers have duties to inform, instruct and train their employeesabout occupational risks and provide them with suitable healthsurveillance. The aim of the study was to evaluate the impactof the Regulations on employees with occupational asthma. Onehundred consecutive patients attending an occupational lungdisease clinic completed a questionnaire assessing the implementationof the COSHH Regulations in their workplace. Twenty-eight percent had a pre-employment inquiry about asthma, 31% had regularhealth surveillance by questionnaires and 19% had regular lungfunction assessment at work. Pre-employment spirometry was carriedout in 44% of the workers who were exposed to one of the originalseven prescribed agents, significantly more than those who wereexposed to other agents (19%) (p < 0.05). Moreover, figuresfor spirometry during employment were 31% and 8% respectively(p < 0.05). The patients who worked after ‘COSHH’but before ‘MS25’ had a tendency to be providedwith health surveillance more than those who worked after both‘COSHH’ and ‘MS25’. Ninety-one per centof the patients had never been informed about the risks of gettingasthma at work and 73% had never seen the safety data sheets.The workers who (1) worked after ‘COSHH’ introduction;(2) worked in larger firms and (3) were exposed to one of theoriginal seven prescribed agents, had a tendency to be informed,instructed and trained more than the rest. However, there wereonly significant statistical differences (p<0.05) in termsof the safety data sheet provision between the cases who workedbefore the time of the legislation and those employed afterwards.     

A study of South Korean casino employees and gambling problems

Background Casino employees are exposed to disproportionatelyhigh levels of gambling, drinking and smoking compared to otheroccupations. Because of their occupation, they have the opportunityto detect and prevent pathological gambling (PG). Aims To identify differences in the mental health status andsocial attitudes towards PG among casino workers in South Koreadepending upon whether they report any gambling problems. Methods Data were collected from 388 full-time casino employees.This data provided information about the prevalence of gamblingproblems, alcohol and tobacco use and depression. Employeeswere grouped according to their scores on the Korean versionof South Oaks Gambling Screen (SOGS), and those employees whogambled without experiencing any gambling problems (Group NP:SOGS = 0) and those who reported any gambling problems (GroupP: SOGS > 0) were compared. An exploratory factor analysesidentified the domains of casino employee social attitudes towardsgambling. Results Employees who reported gambling problems (Group P) reporteda higher prevalence of smoking, alcohol problems and depression(P < 0.01) compared to employees who did not report gamblingproblems (Group NP). The primary employee social attitude towardsgambling was identified by the factor of ‘Disease concept/socialawareness’. Group NP reported more positive attitudesin this domain than Group P (P < 0.01). Conclusions Employees who reported any gambling problems reporteda less positive attitude towards developing the public healthsystem to be responsive to gambling problems. These findingsindicate a need to develop health education programmes thatfocus more specifically on casino employees with gambling problems.     

An evaluation of stress education in the Royal Navy

Background Psychoeducational programmes aim to reduce the morbidityassociated with exposure to stressful events. Although theyare widely used, there are conflicting views as to how or whythey might be effective. Aim To examine exposure to ‘stress’ education withinthe Royal Navy (RN) and ascertain any links between stress educationand mental health status. Methods In all, 1559 RN personnel were surveyed using a studyquestionnaire which asked about exposure to and quality of anystress education provided during service. Participants alsocompleted two measures of psychological health, the GeneralHealth Questionnaire (GHQ)-12 item and the Post-Traumatic StressDisorder Checklist. Odds ratios (ORs) were calculated and 95%confidence intervals were computed using multivariable logisticregression adjusting for socio-demographic variables. Results The response rate was 70%; 47% of the sample reportedhaving received a stress brief during service. Those who reportedhaving received a brief had better general mental health (measuredby the GHQ) than those who had not [adjusted, OR = 0.76 (0.59–0.98)].When brief quality was taken into account, only those who receiveda brief and considered it ‘useful’ were significantlyless distressed [adjusted, OR = 0.65 (0.49–0.86)]. Poor-qualitybriefs were no better than having had no brief at all [adjusted,OR = 1.04 (0.74–1.47)]. Conclusions Our data indicate that only educational stress briefswhich are relevant for the target audience may be beneficial.Simply providing stress briefings, without thought to theirquality, may constitute a waste of resources.     

Salivary acetylcholinesterase as a biomarker for organophosphate exposure

Background Workers exposed to organophosphate (OP) pesticidesare required to undergo periodic statutory medical surveillancein several countries. Aim To study the relationship between serum, erythrocyte andsaliva acetylcholinesterase (AChE) levels and to explore theuse of salivary AChE as potential biomarker for OP exposure. Methods A cross-sectional study was conducted on 19 healthyadult male lead-exposed workers who were undergoing six monthlystatutory medical examination. Passive drool saliva sampleswere collected from each worker. Each blood sample was testedfor serum and erythrocyte AChE, and each saliva sample was testedfor AChE. Results Among the 19 subjects, the mean (±standard deviation)of salivary, erythrocyte and serum AChE/cholinesterase were22.7 (±17.4), 17171 (±1467), 8861 (±1876)U/l, respectively. There was a moderate correlation betweensalivary and erythrocyte AChE (r = 0.42, P = 0.071), but notsalivary and serum AChE (r = –0.17, P = 0.48). The levelof AChE in saliva was 1820 times lower than AChE in erythrocytes. Conclusion It is probably not feasible to use saliva as a replacementfor blood for the measurement of AChE levels. This is becauseof the much lower levels of AChE in saliva relative to erythrocytes,the weak correlation between the two measurements and the previouslyreported high intra-individual variation of salivary AChE.     

Fatigue and health in a seafaring population

Background Occupational fatigue is relatively common withinthe general population and has been linked to reduced performance,injury and longer term ill-health. Despite growing acknowledgementof this problem in the maritime sector, little research hasbeen conducted into the risk factors, prevalence and consequencesof seafarers' fatigue. Aims To examine the prevalence of fatigue among seafarers, identifypotential risk factors and assess possible links with poor performanceand ill-health. Methods Cross-sectional questionnaire survey of seafarers workingin the offshore oil support, short-sea and deep-sea shippingindustries. A number of tools were used including the fatiguesubscale of the profile of fatigue-related symptoms, the CognitiveFailures Questionnaire, the General Health Questionnaire andthe SF36 General Health scale. Results In all, 1855 questionnaires were completed giving anoverall response rate of 20%. Fatigue symptoms were associatedwith a range of occupational and environmental factors, manyunique to seafaring. Reporting a greater number of risk factorswas associated with greater fatigue [e.g. OR = 2.53 (1.90–3.35)for those with three or four risk factors and OR = 9.54 (6.95–13.09)for those with five or more risk factors]. There was also astrong link between fatigue and poorer cognitive and healthoutcomes, with fatigue the most important of a number of riskfactors, accounting for 10–14% of the variance. Conclusions Seafarers' fatigue could impact on safety withinthe industry and may be linked to longer term individual ill-health.It can only be addressed by considering how multiple factorscombine to contribute to fatigue.     

The involvement of occupational health services prior to ill-health retirement in NHS staff in Scotland and predictors of re-employment

OBJECTIVE: To assess the process, causes and outcomes of retirement because of ill-health in NHS staff in Scotland. Particular areas to be investigated include the involvement of occupational health services, access to rehabilitation and redeployment, current health, whether working again and to identify predictors of re-employment. METHOD: An ill-health retirement (IHR) questionnaire was mailed to 863 NHS staff awarded IHR benefits by the Scottish Public Pensions Agency between April 1998 and March 2000. RESULTS: In all, 49% of the 863 postal questionnaires were returned. The most common reasons for retiring were diseases of the musculoskeletal system (38%) and mental disorders (21%). Seventy-one percent of the participants reported their ill-health was partly or completely work related and 29% not work related. Ninety-two percent of NHS staff had attended an occupational health department prior to IHR. Twenty-three percent of participants had no contact with their line manager during their illness prior to retiral. Eighteen percent of individuals were offered the opportunity of working part-time and 15% offered alternative work. Seventeen percent of participants have obtained other work. Predictors of re-employment after IHR were: medical condition, managerial responsibility, improvement of health, wanting to work again, occupation and age at retirement. CONCLUSION: This is the first comprehensive study investigating NHS staff experiences of IHR in Scotland. This study illustrates the need for improved support and rehabilitation for ill-health care workers and that there is the potential to reduce levels of ill-health retirement.     

Overtime work and stress response in a group of Japanese workers

Background Working long overtime hours is considered a causeof mental health problems among workers but such a relationshiphas yet to be empirically confirmed. Aim To clarify the influence of overtime work on response tostress and to assess the role of other stress-related factorson this relationship. Methods The study was conducted among 24 685 employees of acompany in Japan. Stress response, job stressors and socialsupports were assessed by the Brief Job Stress Questionnaire.Participants were divided into five categories of overtime (0–19,20–39, 40–59, 60 h of overtime per month and exemptedemployees). Results The nonadjusted odds ratios for stress response for40–59 and 60 overtime hours per month in reference to0–19 overtime hours were 1.11 [95% confidence interval(CI) 1.03–1.19] and 1.62 (95% CI 1.50–1.76), respectively.After adjustment for self-assessed amount of work, mental workloadand sleeping time, the association between overtime work andstress response disappeared. Conclusions This large cross-sectional study shows that overtimework appears to influence stress response indirectly throughother stress factors such as self-assessed amount of work, mentalworkload and sleeping time.     

Which agents cause reactive airways dysfunction syndrome (RADS)? A systematic review

Aim To identify those agents reported as being associated withreactive airways dysfunction syndrome (RADS). Methods A systematic review was undertaken. Abstracts were screenedand those selected reviewed against pre-determined diagnosticcriteria for RADS. Results Significant information gaps were identified for allmeasures of interest. In some articles, even the causative agentwas not reported. The most commonly reported agents were chlorine(nine subjects), toluene di-isocyanate (TDI) (n = 6) and oxidesof nitrogen (n = 5). Most exposures occurred in the workplace(n = 51) and affected men (60%). Dyspnoea (71%) and cough (65%)were the commonest symptoms. Median symptom duration was 13months (interquartile range = 6.5–43.5) for RADS. Conclusions Although the most commonly reported agent associatedwith RADS was chlorine, the main finding of a general lack ofadequate information on exposure, investigation and outcomesuggests that to better explore RADS a more structured approachto gathering information is required. A minimum data set forreporting RADS cases is proposed.     

Accidental blood and body fluid exposure among doctors

Aim To study the epidemiology and time trends of blood and bodyfluids (BBF) exposures among hospital doctors. Methods A 3-year study was carried out using data from the ExposurePrevention Information Network of four teaching hospitals inthe UK. Results One hundred and seventy-five cases of BBF exposuresin doctors were reported over the 3-year study period. Eighty-one(46%) occurred in senior doctors and 94 (54%) in junior doctors.Junior doctors had a higher rate of BBF exposures compared tosenior doctors: 13 versus 4 incidents per 100 person-years,respectively (relative risk 3, 95% confidence interval 2–4).The most frequent setting for BBF exposures among senior doctorswas the operating theatre/recovery (59%). Among junior doctors,it was the patient room (48%). The commonest original reasonfor use of sharps by junior doctors was the taking of bloodsamples (42%). Among senior doctors, it was suturing (41%). Conclusion While ongoing training efforts need to be directedtowards both junior and senior doctors, our data suggest thatjunior doctors are at higher risk of BBF exposures and may needparticular attention in prevention strategies. An improvementin the safety culture in teaching hospitals can be expectedto reduce the number of BBF exposures.     

Attitudes to job turnover among Finnish anaesthetists

Background Structural changes have led to higher workload andmore frequent conflicts among hospital staff, which in turnhas been shown to be associated with increased employee turnover. Aims To study the willingness of anaesthetists to change theiremployment and factors associated with it. Work-related, individualand family-related factors were investigated as potential influenceson such willingness. Method A postal questionnaire was sent to all working Finnishanaesthetists (N = 550). Results The response rate was 60%; 175 (53% of responders) weremen. Of the respondents, 31% were willing to consider changingto another physician's job and 43% to a profession other thanmedicine. The most important correlates for these views wereconflicts with superiors (odds ratio 6.1; 95% confidence interval2.1–17.7) and co-workers (4.2; 1.4–12.2), low jobcontrol (2.6; 1.4–4.9), a sense of organizational injustice(2.4; 1.3–4.6), stress (6.5; 2.6–16.3) and job dissatisfaction(4.6; 2.4–8.8). Conclusions The establishment of respect, trust and genuinedialogue between co-workers and superiors is needed to minimizethe risk of loss of members of this occupational group.     

Effect of work with visual display units on musculo-skeletal disorders in the office environment

Background The increase in computer and mouse use has been associatedwith an increased prevalence of disorders in the neck and upperextremities. Furthermore, poor workstation design has been associatedwith an increased risk of developing these symptoms. Aim The aims of this study were (i) to estimate the prevalenceof musculo-skeletal disorders among full-time visual displayunit (VDU) users; (ii) to examine how the prevalence variesby work environment; and (iii) to explore the association withwork factors. Method A survey was carried out on the effect of work with VDUson musculo-skeletal disorders in workers in the office environmentof 56 workplaces. Office workers (n = 298), customer serviceworkers (n = 238) and designers (n = 247) were studied. Results For all the occupations combined, the 12 month prevalencesof musculo-skeletal symptoms in the neck, shoulders, elbows,lower arms and wrists, and fingers were 63, 24, 18, 35 and 16%,respectively. The study indicated that musculo-skeletal painis common among computer workers in offices. There was no strongassociation between the duration of computer work and pain orbetween the duration of mouse use and pain, but workers' perceptionof their workstation as being poor ergonomically was stronglyassociated with an increased prevalence of pain. Conclusions Musculo-skeletal symptoms are common, but the durationof daily keyboard and mouse use had no connection with musculo-skeletalsymptoms. Instead, more consideration should be paid to theergonomics of workstations, the placing of the mouse, the posturesof the upper extremities and the handling of the mouse.     

Return to work after ill-health retirement in Scottish NHS staff and teachers

BACKGROUND: Most major public and private sector pension schemes have provision for ill-health retirement (IHR) for those who become too ill to continue to work before their normal retirement age. AIM: To compare the causes, process and outcomes of IHR in teachers and National Health Service (NHS) staff in Scotland. METHODS: A total of 537 teachers and 863 NHS staff who retired due to ill-health between April 1998 and March 2000 were mailed an IHR questionnaire by the Scottish Public Pensions Agency. RESULTS: The response rate for teachers was 53% and for NHS staff 49%. The most common cause of IHR was musculoskeletal disorders for NHS staff and mental disorders for teachers. Teachers retired at a younger average age than NHS staff. Ninety-two per cent of NHS staff but only 11% of teachers attended occupational health services (OHS) prior to IHR. Eighteen per cent of NHS staff and 9% of teachers were offered part-time work by their current employer in response to their ill-health. Fifteen per cent of NHS staff and 5% of teachers were offered alternative work prior to retirement. Seventeen per cent of NHS staff and 36% of teachers subsequently found employment. Multiple logistic regression analyses showed the following variables as independent predictors of subsequent employment: occupational group, age group, sex, managerial responsibility and cause of IHR. CONCLUSIONS: Return to work after IHR suggests that some IHR could be avoided. Teachers had a higher rate of return to work and much less access to OHS.     

Exposures to blood and body fluids in Brazilian primary health care

Background Primary health care workers (HCWs) represent a growingoccupational group worldwide. They are at risk of infectionwith blood-borne pathogens because of occupational exposuresto blood and body fluids (BBF). Aim To investigate BBF exposure and its associated factors amongprimary HCWs. Methods Cross-sectional study among workers from municipal primaryhealth care centres in Florianópolis, Southern Brazil.Workers who belonged to occupational categories that involvedBBF exposures during the preceding 12 months were interviewedand included in the data analysis. Results A total of 1077 workers participated. The mean incidencerate of occupational BBF exposures was 11.9 per 100 full-timeequivalent worker-years (95% confidence interval: 8.4–15.3).The cumulative prevalence was 7% during the 12 months precedingthe interview. University-level education, employment as a nurseassistant, dental assistant or dentist, higher workload score,inadequate working conditions, having sustained a previous occupationalaccident and current smoking were associated with BBF exposures(P 0.05). Conclusions Primary Health Care Centres are working environmentsin which workers are at risk of BBF exposures. Exposure surveillancesystems should be created to monitor their occurrence and toguide the implementation of preventive strategies.     

Factors influencing return to work after surgical treatment for carpal tunnel syndrome

Background Controversy exists regarding the factors influencingthe duration of work incapacity after surgically treated carpaltunnel syndrome (CTS). Aim To determine relevant factors related to return to work. Methods Surgical technique, clinical factors, demographic factors,other medical problems, psychosocial factors, work-related andeconomical factors were reviewed in patients operated on forCTS. Statistical multivariate analyses were performed to identifythe baseline factors influencing the work incapacity period. Results A total of 107 cases were reviewed. Professional exposureto repetitive movements and heavy manual handling activity wereassociated with a longer return-to-work interval. The durationof work incapacity period was not significantly related to thesocioprofessional category of the patient (self-employed oremployee) or to the type of the procedure (open versus endoscopicsurgery). Conclusion Work-related features have a more important influenceon return to work than personal, pathological or surgical features.     

Ill-health retirement: a survey of decision making by occupational physicians working for local authority fire and police services

AIMS: To investigate the effect of qualifications, experience and service on ill-health retirement decisions made by police force and fire brigade medical advisers. METHODS: Doctors advising UK fire and police authorities attending a conference were given 16 case summaries from experienced fire and police advisers and asked to predict the outcome in terms of return to work or ill-health retirement. The answers were scored by assessing whether the outcome predicted by the participant agreed with the case setter. Correlation coefficients were calculated and a kappa coefficient was determined for assessing inter-participant variation. RESULTS: Forty-seven doctors attended, 44 participated and the responses of 39 (86%) were analysed. Over half the doctors participating had held their post for less than 5 years. The majority (>50%) agreed with the case setter in 11 case summaries and in five cases the agreement was strong (>75%). The majority disagreed in five cases, with < or =80% dissenting in three cases. There was wide variation in the inter-participant variation (kappa = -0.333 to +0.5) but the total agreed score correlated significantly (P < 0.05) with experience and service as a fire or police adviser (kappa = 0.33) and ill-health retirement agreement correlated significantly with experience (kappa = 0.49). There was no correlation between the level of qualification and total correct decisions. CONCLUSIONS: Whilst we found general agreement overall, our results suggest that there is inconsistency in ill-health retirement decision making by police and fire service medical advisers in certain cases. Experience appears to improve the likelihood of agreement in decision making.     

Peer support in an occupational setting preventing LBP-related sick leave

Background Low back pain (LBP) is among the most frequent causesof sickness absence in Norway, and it is thought that it couldbe reduced by 30–50% if present day knowledge was implementedin the workplace. Evidence-based interventions in occupationalsettings to prevent sickness absence are still lacking. Aim To evaluate whether peer support would be able to modifygeneral beliefs about LBP, pain experiences, health care utilizationand sickness absence due to back pain. Methods In addition to a media campaign in two Norwegian countiesin 2002–05, aiming at improving beliefs about LBP in thegeneral public, the ‘Active Back’ project traineda peer adviser in six participating workplaces. The task ofthis peer adviser was to provide information aimed at reducingfear of the pain, supportive advice and arrange for modificationsof workloads, etc., for a limited period of time. Results The prevalence of back pain remained constant throughoutthe study period, but self-reported intensity of LBP decreasedat the end. There was a small decline in use of health careprofessionals and significant improvements in beliefs, in linewith the messages of the campaign. Total sickness absence decreasedby 27% and the LBP-related sickness absence by 49%. Conclusion The combination of peer support and modified workloadseemed to have additional effects to the general media campaign,and resulted in decline in sickness absence and improvementsin beliefs about back pain.
