Issues of Concern for the Aging Anesthesiologist

Age and its impact on crisis management performance and learning after simulation-based education by acute care physicians: a multicentre prospective cohort study

BACKGROUND

Physiological changes associated with ageing could negatively impact the crisis resource management skills of acute care physicians. This study was designed to determine whether physician age impacts crisis resource management skills, and crisis resource management skills learning and retention using full-body manikin simulation training in acute care physicians.

METHODS

Acute care physicians at two Canadian universities participated in three 8-min simulated crisis (pulseless electrical activity) scenarios. An initial crisis scenario (pre-test) was followed by debriefing with a trained facilitator and a second crisis scenario (immediate post-test). Participants returned for a third crisis scenario 3-6 months later (retention post-test).

RESULTS

For the 48 participants included in the final analysis, age negatively correlated with baseline Global Rating Scale (GRS; r=-0.30, P<0.05) and technical checklist scores (r=-0.44, P<0.01). However, only years in practice and prior simulation experience, but not age, were significant in a subsequent stepwise regression analysis. Learning from simulation-based education was shown with a mean difference in scores from pre-test to immediate post-test of 2.28 for GRS score (P<0.001) and 1.69 for technical checklist correct score (P<0.001); learning was retained for 3-6 months. Only prior simulation experience was significantly correlated with a decreased change in learning (r=-0.30, P<0.05).

CONCLUSIONS

A reduced amount of prior simulation training and increased years in practice, but not age on its own, were significant predictors of low baseline crisis resource management performance. Simulation-based education leads to crisis resource management learning that is well retained for 3-6 months, regardless of age or years in practice.

'Quit while you are ahead - and smell the roses!' A survey of retired Fellows of the Australian and New Zealand College of Anaesthetists

There are no published data on the age of retirement of anaesthetists in Australia and New Zealand. We surveyed 622 retired Fellows of the Australian and New Zealand College of Anaesthetists to determine their ages of complete retirement from clinical practice, demographics, and whether they had retired at the age they had intended to retire. We also aimed to explore factors affecting the decision to retire, the practice of 'winding down', common post-retirement activities, and the arrangement of personal and professional affairs. Responses were received from 371 specialists (response rate 60%). The mean (standard deviation) age of retirement was 65.2 (6.9) years. The mean (standard deviation) retirement ages ranged from 62.0 (7.1) years (those who retired earlier than planned) to 68.0 (4.3) years (those who retired later than they had intended). The mean (standard deviation) age of retirement of the male respondents was 66.0 (6.5) years, and for female respondents was 62.7 (7.7) years. Two hundred and thirty-three respondents (63%) reported winding down their practice prior to retirement, and 360 (97%) had made a will. Poor health and loss of confidence were the two most common factors in the retirement decisions of those who retired earlier than they had planned. Our results may assist current practitioners plan for retirement, and suggest strategies to help health services, departments and private groups accommodate individuals in winding down their practice.

The senior anesthesiologists and their medical profession in Korea: based on a survey

BACKGROUND

The number of aging physicians is increasing as the global population ages. With aging, anesthesiologists would be expected to experience changes in their professional position. Therefore, we aimed to investigate the current professional status of Korean anesthesiologists aged over 60 years.

METHODS

Registered anesthesiologists aged over 60 years in Korea were invited for a survey. The questionnaire addressed 10 subjects with 40 questions that focused on demographics, practical activities, work conditions, difficulties experienced due to physical changes caused by aging, and economic status.

RESULTS

In total, 122 anesthesiologists responded to the survey (response rate: 15.7%). Of them, 30.3% were working in honorary and advisory positions at tertiary hospitals, while 19.7% were working as pain physicians. Majority of the respondents were working for 5 days a week (41.8%) and 6-8 hours/day (48.4%). Majority of them (79.5%) were generally satisfied with their present life.

CONCLUSIONS

Majority of the senior anesthesiologists were working at general hospitals and they reported being "satisfied" with the current status of their life. However, the clinical practice and retirement strategies of senior anesthesiologists need to be evaluated systematically to prepare for the continuing gradual increase in the number of senior anesthesiologists.

Assessment of Postoperative Cognitive Dysfunction: Results From a Survey of Turkish Anaesthesiologists

Objective

Postoperative cognitive dysfunction (POCD) is one of the most common complications in elderly surgical patients. We conducted a survey study to evaluate the perspectives of Turkish anaesthesiologists on postoperative cognitive disorders.

Methods

We conducted a prospective online survey with questions and answers were recorded either in a Likert scale from 1 to 5 (completely disagree to completely agree) or as yes/no/do not know types of answers. Potential participants were contacted through an e-mail that included a brief introductory note, instructions, a link to the survey and the authors' contact information.

Results

We analysed 129 surveys (9.9% of total potential respondents). The majority believed that the risk of cognitive side effects should be considered when choosing the type of anaesthesia (87.6%) and that preoperative cognitive function should be routinely assessed (74.4%). When caring for an agitated and confused patient postoperatively, 56.6%, protocols to screen and manage postoperative cognitive disorders were rarely used. Nearly all respondents believe that postoperative delirium and POCD are neglected areas in anaesthesiology.

Conclusion

Overall, participants perceive postoperative cognitive disorders as important adverse outcomes following surgery and anaesthesia. They are aware of the main risk factors for their development but may lack information on the prevention and management postoperatively.

Outcome of transplantation performed outside the regular working hours: A systematic review and meta-analysis of the literature

Transplant procedures are frequently performed outside the regular working hours (after hours). In general surgery, several studies observed worse outcomes for operations performed after hours. The predetermined hypothesis was that patients undergoing transplantation during after hours might suffer from an excess in post-operative mortality and morbidity when compared to patients undergoing transplantations during the regular working hours. A systematic review of the PubMed database identified 11,993 records, of which eleven cohort studies including a total of 287,741 patients investigated the association between the starting time of transplant surgery and postoperative mortality (primary outcome) and/or morbidity (secondary outcome). Eight studies evaluated kidney transplants (in 165,277 patients), two studies analyzed liver transplants (in 95,346 patients), and one study investigated transplantations of thoracic organs (in 27,118 patients). Results were conflicting with two studies (in liver and lung transplantation) showing an increased mortality for transplantations performed after hours, and five studies showing no effects on mortality. A meta-analysis on estimates from four studies yielded a hazard ratio of 1.01 (95% CI, 0.98 to 1.04) for mortality comparing transplantations performed during versus outside the regular working hours. The evidence was also inconclusive for a variety of morbidity outcomes with studies demonstrating either a deterioration of outcome, no effect or an improved outcome for after hours procedures. On the basis of the available evidence, it appears impossible to give an unequivocal recommendation regarding starting times in transplant surgery.

Does the age of acute care physicians impact their (1) crisis management performance and (2) learning after simulation-based education? A protocol for a multicentre prospective cohort study in Toronto and Ottawa, Canada

INTRODUCTION

The proportion of older acute care physicians (ACPs) has been steadily increasing. Ageing is associated with physiological changes and prospective research investigating how such age-related physiological changes affect clinical performance, including crisis resource management (CRM) skills, is lacking. There is a gap in the literature on whether physician's age influences baseline CRM performance and also learning from simulation. We aim to investigate whether ageing is associated with baseline CRM skills of ACPs (emergency, critical care and anaesthesia) using simulated crisis scenarios and to assess whether ageing influences learning from simulation-based education.

METHODS AND ANALYSIS

This is a prospective cohort multicentre study recruiting ACPs from the Universities of Toronto and Ottawa, Canada. Each participant will manage an advanced cardiovascular life support crisis-simulated scenario (pretest) and then be debriefed on their CRM skills. They will then manage another simulated crisis scenario (immediate post-test). Three months after, participants will return to manage a third simulated crisis scenario (retention post-test). The relationship between biological age and chronological age will be assessed by measuring the participants CRM skills and their ability to learn from high-fidelity simulation.

ETHICS AND DISSEMINATION

This protocol was approved by Sunnybrook Health Sciences Centre Research Ethics Board (REB Number 140-2015) and the Ottawa Health Science Network Research Ethics Board (#20150173-01H). The results will be disseminated in a peer-reviewed journal and at scientific meetings.

Nonelective surgery at night and in-hospital mortality: Prospective observational data from the European Surgical Outcomes Study

BACKGROUND

Evidence suggests that sleep deprivation associated with night-time working may adversely affect performance resulting in a reduction in the safety of surgery and anaesthesia.

OBJECTIVE

Our primary objective was to evaluate an association between nonelective night-time surgery and in-hospital mortality. We hypothesised that urgent surgery performed during the night was associated with higher in-hospital mortality and also an increase in the duration of hospital stay and the number of admissions to critical care.

DESIGN

A prospective cohort study. This is a secondary analysis of a large database related to perioperative care and outcome (European Surgical Outcome Study).

SETTING

Four hundred and ninety-eight hospitals in 28 European countries.

PATIENTS

Men and women older than 16 years who underwent nonelective, noncardiac surgery were included according to time of the procedure.

INTERVENTION

None.

MAIN OUTCOME MEASURES

Primary outcome was in-hospital mortality; the secondary outcome was the duration of hospital stay and critical care admission.

RESULTS

Eleven thousand two hundred and ninety patients undergoing urgent surgery were included in the analysis with 636 in-hospital deaths (5.6%). Crude mortality odds ratios (ORs) increased sequentially from daytime [426 deaths (5.3%)] to evening [150 deaths (6.0%), OR 1.14; 95% confidence interval 0.94 to 1.38] to night-time [60 deaths (8.3%), OR 1.62; 95% confidence interval 1.22 to 2.14]. Following adjustment for confounding factors, surgery during the evening (OR 1.09; 95% confidence interval 0.91 to 1.31) and night (OR 1.20; 95% confidence interval 0.9 to 1.6) was not associated with an increased risk of postoperative death. Admittance rate to an ICU increased sequentially from daytime [891 (11.1%)], to evening [347 (13.8%)] to night time [149 (20.6%)].

CONCLUSION

In patients undergoing nonelective urgent noncardiac surgery, in-hospital mortality was associated with well known risk factors related to patients and surgery, but we did not identify any relationship with the time of day at which the procedure was performed.

The ageing practitioner: ANZCA's recommendations

OBJECTIVES

The aim is to present recommendations of the Australian and New Zealand College of Anaesthetists (ANZCA) with respect to practice implications for ageing specialists, together with brief discussion of effects of ageing on professional medical capabilities and recommendations on preparing to retire from medical practice.

CONCLUSIONS

Practitioners should recognise that planning for retirement is part of good management of a medical career, and that the ageing process will inevitably compromise their ability to treat patients safely unless they retire at the appropriate time. Planning should include adequate financial preparation, and cultivation of interests and friends outside medicine. Practitioners should also realise that insight is likely to be compromised, so that they should seek colleagues who are trusted to advise them if/when they begin to lose competency. Lastly all practitioners should ensure that they consult a General Practitioner frequently, and that they have arranged all the proper legal instructions such as a Will, a Power of Attorney and an Advanced Health Directive.The ANZCA recommendations concerning ageing specialists have wide application to all medical specialties, not just for anaesthetists, and therefore all Medical Colleges should generate their own specific recommendations for ageing practitioners and the general effects of fatigue particularly for aged practitioners.

The aging anesthesiologist: a narrative review and suggested strategies

PURPOSE

To address an aging anesthesia workforce, we review the relevant changes and implications associated with age in order to stimulate discussion at the individual, local, and national levels regarding appropriate changes in practice aimed at protecting patient safety.

PRINCIPAL FINDINGS

In a 2013 survey of Canadian Anesthesiologists, 22% were aged 55-64 yr, 7% were aged 65-74 yr, and 3% were older than 74 yr. Clinical abilities decline with age, making older anesthesiologists more likely than their younger colleagues to be associated with adverse patient events. Anesthesiologists older than 65 yr in Ontario, Quebec, and British Columbia had 50% more cases involving litigation and almost twice the number of cases involving severe patient injury compared with anesthesiologists younger than 51 yr of age. In the absence of overt deterioration in skills, decisions about reducing activities and retirement are left largely to individuals despite their limited ability to self-assess competence. This state of affairs may contribute to the increased incidence of adverse events and poor patient outcomes.

CONCLUSIONS

Provincial regulatory bodies have peer assessment programs to evaluate physicians at random, following a complaint, and at certain ages, but all have limitations. Simulation has been used widely for training and assessment in the aviation industry as well as in automobile driving exams. Simulation can assess crisis recognition and management, which is crucial in anesthesiology and not well assessed by other methods, and could assist elderly anesthesiologists during the pre-retirement phase of their careers. A standardized schedule for winding down would have advantages for physicians, their department, and their patients. A suggested schedule might include no further on-call duties for those aged 60 yr and older, no further high-acuity cases for those aged 65 yr and older, and retirement from operating room (OR) clinical practice (with possible continuation of non-OR clinical or other non-clinical activities, if desired) at age 70 yr. These timelines could be extended with satisfactory performance in annual simulation sessions involving assessment and practice in crisis management.

Practice policies for older anesthesiologists in academic departments: a national survey of academic departmental chairpersons

STUDY OBJECTIVES

To determine 1) which proportion of academic departments have policies concerning older anesthesiologists, 2) whether departments with such policies, particularly those related to call, had characteristics such as departmental size and proportions of older anesthesiologists that differed from departments without these policies, 3) if departments routinely screened their older members for problem behaviors, and 4) if departments provided nonclinical roles for older anesthesiologists.

DESIGN

Survey instrument.

SETTING

Academic medical centers.

MEASUREMENTS

An anonymous, web-based questionnaire that included questions on demographics and specific policy-related issues was sent to chairpersons of all academic anesthesia departments in the ASA database.

MAIN RESULTS

No department directly addressed every issue listed in the survey. Department size and the number of anesthesiologists over 60 years of age were unrelated to whether that department had one or more policies for older anesthesiologists. Twenty percent of programs stopped night call at age 60 years. Most departments did not exempt older anesthesiologists of any age from call responsibilities. Almost all departments tracked critical incidents and errors in technique and/or judgment. Almost three quarters tracked substance abuse, and over half of the responding departments tracked physical and emotional impairment and fixation errors. A third of departments tracked all 6 types of problem behavior. Only 12% had specific assessment tools for tracking problem behaviors in the clinic, and no department used these tools specifically for older anesthesiologists. While only 17% of departments directed older anesthesiologists into nonclinical roles, older clinicians had teaching, mentoring, and administrative roles within most of the departments.

CONCLUSIONS

Relatively few departments had specific policies for older anesthesiologists that addressed the issues raised in the survey. Further research is needed to determine whether departments should decrease ambiguity of their policies, formulate explicit policies for older anesthesiologists, especially in regard to call, and assess problem behaviors more directly.

The senior obstetrician requesting obstetric privileges

As the American physician workforce matures in age, senior physicians on the active clinical staff may become vulnerable to diminished professional performance. Many physicians compensate by using experiential rather than analytic methods to effectively solve clinical problems. Surgical expertise also may be at risk in these circumstances. Organized medical staffs must confront these realities before adverse events are reported as patient safety is their primary responsibility. The appropriate credentialing process will enable talented and experienced senior clinicians to continue to provide high quality medical care.

The financial cost of doctors emigrating from sub-Saharan Africa: human capital analysis

OBJECTIVE

To estimate the lost investment of domestically educated doctors migrating from sub-Saharan African countries to Australia, Canada, the United Kingdom, and the United States.

DESIGN

Human capital cost analysis using publicly accessible data.

SETTINGS

Sub-Saharan African countries.

PARTICIPANTS

Nine sub-Saharan African countries with an HIV prevalence of 5% or greater or with more than one million people with HIV/AIDS and with at least one medical school (Ethiopia, Kenya, Malawi, Nigeria, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe), and data available on the number of doctors practising in destination countries.

MAIN OUTCOME MEASURES

The financial cost of educating a doctor (through primary, secondary, and medical school), assuming that migration occurred after graduation, using current country specific interest rates for savings converted to US dollars; cost according to the number of source country doctors currently working in the destination countries; and savings to destination countries of receiving trained doctors.

RESULTS

In the nine source countries the estimated government subsidised cost of a doctor's education ranged from $21,000 (£13,000; €15,000) in Uganda to $58,700 in South Africa. The overall estimated loss of returns from investment for all doctors currently working in the destination countries was $2.17bn (95% confidence interval 2.13bn to 2.21bn), with costs for each country ranging from $2.16m (1.55m to 2.78m) for Malawi to $1.41bn (1.38bn to 1.44bn) for South Africa. The ratio of the estimated compounded lost investment over gross domestic product showed that Zimbabwe and South Africa had the largest losses. The benefit to destination countries of recruiting trained doctors was largest for the United Kingdom ($2.7bn) and United States ($846m).

CONCLUSIONS

Among sub-Saharan African countries most affected by HIV/AIDS, lost investment from the emigration of doctors is considerable. Destination countries should consider investing in measurable training for source countries and strengthening of their health systems.

[Every life counts : suicide by anesthetists]

This article has its roots in the consternation of head anesthetists over the loss of colleagues. Anesthesia, intensive care medicine, emergency medicine and pain therapy has lost too many first class colleagues through suicide, addiction, severe depression and other causes. It is time to direct attention not exclusively to patients but also to apply an important occupational principle in the rescue service and intensive care medicine to the profession of anesthetists: Every life counts! The following article supplies information on the frequency, methods and possible reasons for suicide by physicians and suggestions for the prevention of suicide as well as treatment of physicians who are at risk of suicide will be presented.

High-fidelity simulation demonstrates the influence of anesthesiologists' age and years from residency on emergency cricothyroidotomy skills

BACKGROUND

Age-related deterioration in both cognitive function and the capacity to control fine motor movements has been demonstrated in numerous studies. However, this decline has not been described with respect to complex clinical anesthesia skills. Cricothyroidotomy is an example of a complex, lifesaving procedure that requires competency in the domains of both cognitive processing and fine motor control. Proficiency in this skill is vital to minimize time to reestablish oxygenation during a "cannot intubate, cannot ventilate" scenario. In this prospective, controlled, single-blinded study, we tested the hypothesis that age affects the learning and performance of emergency percutaneous cricothyroidotomy in a high-fidelity simulated cannot intubate/cannot ventilate scenario.

METHODS

Thirty-six staff anesthesiologists (19 aged younger than 45 years and 17 older than 45 years) managed a high-fidelity cannot intubate/cannot ventilate scenario in a high-fidelity simulator before and after a 1-hour standardized training session. The group division cutoff age of 45 years was based on the median age of our sample subject population before enrollment. The scenarios required the insertion of an emergency percutaneous cricothyroidotomy. We compared cricothyroidotomy skills in the older group with those in the younger group using procedural time, 5-point task-specific checklist score, and global rating scale score. Correlation based on age, years from residency, weekly clinical hours worked, previous continuing medical education in airway management, and previous simulation experience was also performed.

RESULTS

In both prestandardization and poststandardization, age and years from residency correlated with procedural time, checklist scores, and global rating scores. Baseline, prestandardization variables were all better for the younger group, with a mean age of 37 years, compared with the older group, with a mean age of 58 years. Procedural time was 100 (72-128) seconds versus 152 (120-261) seconds. Checklist scores were 7.0 (6.1-8.0) versus 6.0 (4.8-8.0). Global rating scale scores were 22.0 (17.8-29.8) versus 17.5 (10.4-20.6). After the 1-hour standardized training session, the younger group continued to perform better than the older group with procedural time of 75 (66-91) seconds versus 87 (78-123) seconds, checklist scores of 10.0 (9.1-10.0) versus 9.0 (8.0-10.0), and global rating scale scores of 35.0 (32.1-35.0) versus 32.0 (29.0-33.8). Regression analysis was performed on the poststandardization data. Both age and years from residency independently affected procedural time, checklist scores, and global rating scale scores (all P < 0.05).

CONCLUSIONS

Baseline proficiency with simulated emergency cricothyroidotomy is associated with age and years from residency. Despite standardized training, operator age and years from residency were associated with decreased proficiency. Further research should explore the potential of using age and years from residency as factors for implementing periodic continuing medical education.

The impact of a single 24 h working day on cognitive and psychomotor performance in staff anaesthesiologists

BACKGROUND AND OBJECTIVE

The profession of anaesthesiologist is demanding and potentially hazardous. Extended work shifts combined with intensive work load may adversely affect physicians' performance. The aim of this study was to explore the impact of a single in-hospital 24 h shift on the cognitive and psychomotor performance of anaesthesiologists in a surgical emergency department.

METHODS

Following ethical and institutional approval, 11 staff anaesthesiologists [six men, five women, age 48 (35-50), years of experience 17 (7-20), median (range)] successfully completed the study protocol. Four computer-generated psychological tests (CRD, Complex Reactionmeter Drenovac, Croatia) consisting of light signal position discrimination (CRD 311), simple visual orientation (CRD 21), simple arithmetic operations (CRD 11), and complex psychomotor coordination (CRD 411) were used to measure objective parameters of cognitive and psychomotor performance at four time points (D1 = 8:00 a.m., D2 = 3:00 p.m., D3 = 11:00 p.m.; and D4 = 7:00-8:00 a.m. next day) during the 24 h working day. The control testing on an ordinary working day was performed at two time points (C1 = 8:00 a.m., C2 = 3:00 p.m.). Three parameters were recorded: total test solving time (TTST), total variability, and total number of errors for all four tests.

RESULTS

TTST was significantly impaired during the 24 h shift in all tests, and TTST was prolonged in CRD 21 test at different time points from 1.6 +/- 1.4 to 5.5 +/- 1.6 s compared with the control (F = 6.39, P = 0.001). The reaction times were prolonged from 1.3 +/- 1.8 to 5.4 +/- 1.2 s (F = 3.49, P = 0.009) in CRD 311, from 3.8 +/- 9.0 to 34.3 +/- 5.8 s (F = 5.05, P = 0.002) in CRD 11 TTST, and from 0.8 +/- 3.0 to 16.3 +/- 8.6 s (F = 2.67, P = 0.034) in CRD 411. Total variability was significantly altered during the 24 h shift only in CRD 411 (F = 2.63, P = 0.036). There was no difference in the total number of errors between the 24 h shift and the ordinary working day.

CONCLUSION

Anaesthesiologists' 24 h working day in the emergency department altered cognitive and psychomotor function in comparison with ordinary working days. Speed, reliability and mental endurance (measured by TTST) were significantly impaired in all four tests. Stability and reaction time (measured by total variability) were only slightly impaired. Paradoxically, attention and alertness (measured by total number of errors) were not adversely affected. In conclusion, anaesthesiologists' psychomotor performance was impaired during the single 24 h shift.

Issues of concern to emergency physicians in pre-retirement years: a survey

BACKGROUND

Many members of the American College of Emergency Physicians are now over the age of 50. Little is known regarding age-specific issues that may impact the careers of emergency physicians in the latter stages of their professional lives.

OBJECTIVES

To determine issues of concern regarding aging and retirement among a cohort of emergency physicians in pre-retirement years.

METHODS

A survey of a randomized sample of 1000 American College of Emergency Physicians members over the age of 55 years was conducted with two separate mailings in the fall of 2006 and winter of 2007. The survey instrument consisted of 30 questions relating primarily to issues of health, finances, and the ability to practice emergency medicine. Four open-ended questions were included at the end of the survey, relating to means of promoting career longevity.

RESULTS

There were 802 usable responses received (response rate 80%). The average respondent was 57 years old and worked 30 clinical and 12 non-clinical h per week. The average estimated time to complete retirement was 7.8 years. Respondents generally viewed themselves as competent clinicians with improved ability to relate to patients and staff and little decline in procedural skills. However, a substantial proportion reported age-related concerns. Seventy-four percent reported less ability to recover from night shifts, 44% reported a higher level of emotional exhaustion at end of shift, 40% reported less ability to manage heavy patient volume, 36% reported less ability to handle stress of emergency medicine, 28% reported health limitations on ability to practice, 28% reported memory somewhat or considerably worse, and 25% reported less ability to incorporate new modalities of diagnosis and treatment. With regard to retirement-related issues, 42% reported concerns about adequate financial preparations and 44% reported concerns regarding loss of identity upon retirement. The practice modifications most commonly reported to impact career longevity were the reduction or elimination of night shifts, a reduction in the number of hours per shift, and an increase in physician and support staffing.

CONCLUSIONS

Respondents to this survey generally viewed themselves as competent, empathic practitioners. Yet a substantial percentage acknowledged at least some degree of cognitive or physical decline. The results suggest a role for the national organizations in emergency medicine in endorsing practice modifications that promote career longevity and clinical competence among its senior members.

The older anaesthetist

It is not possible to generalise about the way in which increasing years affect the performance of an individual anaesthetist. Physical and mental deterioration occurs as we age; most anaesthetists will be able to reach the normal retirement age of 65 years without that deterioration affecting their clinical practice. In some, however, decreasing competence and an unwillingness to embrace a continuing education regime may offer a direct threat to patient safety. Stress and 'burnout' are common in anesthetists; clinical depression can often be one of the factors involved. Continuing involvement in the on-call rota is a potent stressor. Airline pilots are required to retire at 60 years; the feasibility and desirability of applying this process to anaesthetists are discussed. Employers have a duty to provide employees with adequate and achievable demands in relation to their agreed hours of work and to have in place policies and procedures to offer adequate support.

Post-duty psychomotor performance in young and senior anaesthetists

BACKGROUND AND OBJECTIVE

The level of performance in junior and senior anaesthetists was investigated after 24-h shift working and on-call duties.

METHODS

Pre- and post-duty psychomotor function, influence on response time, cognitive function and well-being in 23 individuals (13 junior and 12 senior anaesthetists) was assessed before and after 24-h in-house on-call duty. Subjective perception of tiredness and concentration abilities was estimated by applying a visual analogue scale.

RESULTS

The self-assessed tiredness prior to duty was high in both age groups and significantly increased in senior anaesthetists after night duty (P = 0.01). Post-duty impairment of concentration abilities was reported in both groups. Comparing results from pre- and post-duty psychometric testing showed a comparable decline in junior and senior anaesthetists as well. Assessment of burnout showed a significant lack of personal accomplishment in junior anaesthetists as compared to their older colleagues (P = 0.038). Senior anaesthetists judged their contribution to patient well-being significantly higher than did their younger colleagues (P = 0.035).

CONCLUSIONS

Although tiredness and subjective impairment of concentration abilities was high in senior anaesthetists after 24-h in-house on-call duty, performance assessed by psychometric testing does not support the hypothesis that senior colleague's performance cannot keep up with routine hospital shift work.

Pathophysiological changes in the elderly

Demographic data indicate an increasing workload of geriatric anaesthesia due to advancing life expectancy and reduced thresholds for high-invasive and high-risk surgery in the elderly. Chronological and biological age may be inconsistent, and the existence of age-related changes may vary between organ systems in the same individual. Age itself is not an illness, but is the most important contributing factor for perioperative complications and adverse outcome when the overall narrowed margins of organ function reserve are transgressed during the perioperative period. Age-related changes in the cardiovascular, pulmonary, nervous, metabolic and locomotive systems that are frequently present in the elderly are discussed with regard to their potential relevance to anaesthesiology. In conclusion, listing current diagnoses will not be sufficient in the assessment of the geriatric patient because age-related changes do not necessarily manifest as pathological entities. Rather, pre-operative examination should focus on determination of individual margins of organ function reserve.
