Prevalence and risk factors for substance abuse and dependence among anaesthetists: a national survey

OBJECTIVE: Addiction behaviours in the anaesthetist population have been recognized as a significant health-related issue and its scope is a matter of concern. METHODS: A national survey conducted among French anaesthetists consisted of a questionnaire designed to elicit information related to demographics, and work conditions, as well as substance consumption status. The study investigated the following: tobacco, alcohol, tranquillizers-hypnotics, and other agents such as cannabis, cocaine, opiates and anaesthetic agents. Respondents were classified in two categories: (no use and use)-(abuse and dependence). An univariate and multivariate analysis were performed to determine risk factors associated with drug abuse and dependence. RESULTS: 3,476 physicians responded to the questionnaire (38.0% response rate); 22.7% were daily tobacco smokers; 10.9% were abuser or dependent to one or more substances other than tobacco i.e. alcohol (59.0%), tranquillizers and hypnotics (41.0%), cannabis (6.3%), opiates (5.5%), and stimulants (1.9%). Sleep disturbances and negative perception of work environment were more frequently reported among addicted anaesthetists. CONCLUSION: In French anaesthetists, addiction is mainly related to alcohol consumption but includes a broad spectrum of substances. Addicted subjects report issues around work environment that may have contributed to the development of their pathology.     

The patients' perception of the anaesthetist in a Swiss university hospital

OBJECTIVES: The role or recognition of the anaesthetist as an independent medical specialist has been the subject of many studies. Since most of this work was performed in English speaking countries, only few data are available for Germany, Austria, or Switzerland. The goal of this study was to determine how much knowledge patients had of the training and activities of anaesthetists. The study included patients ( n=685) who underwent elective operations in all surgical subspecialties at the University Hospital of Basel. METHODS: The data were collected using a questionnaire distributed at the end of the preoperative visit, which included 14 different questions examining the role of the anaesthetist. RESULTS: Surprisingly, and in contrast to previous studies, almost all patients (99%) knew that the anaesthetist is a qualified physician. In addition, 75% of the patients were aware that the anaesthetist is also engaged in activities outside the operating room; these percentages compare favourably with previous results. However, when asked about the specifics of these activities or about how long it takes to train an anaesthetist, the Swiss patients knew little more than patients from other countries. Only one fifth of all patients estimated the duration of postgraduate training correctly and 45% thought that the anaesthesia team worked under the supervision of the surgical team. Previous anaesthetic experiences as well as additional informational material such as a booklet or videofilm did not improve the patients' knowledge with respect to the training or activities of anaesthetists. DISCUSSION: Since other even more elaborate and expensive methods such as large exhibitions, national anaesthesia days, or increased coverage on radio and television also failed to enhance patients' knowledge, the focus is once again on the relationship between the patient and anaesthetist. If we wish to improve the role and recognition of anaesthetists for patients and/or the public, the anaesthetist must be visible for the patients as a true physician in the pre- and postoperative period. To improve this important patient-anaesthetist relationship, we have begun a training program in communication skills for all physicians in our department.     

The contribution of the anaesthetist to risk‐adjusted mortality after cardiac surgery

It is widely accepted that the performance of the operating surgeon affects outcomes, and this has led to the publication of surgical results in the public domain. However, the effect of other members of the multidisciplinary team is unknown. We studied the effect of the anaesthetist on mortality after cardiac surgery by analysing data collected prospectively over ten years of consecutive cardiac surgical cases from ten UK centres. Casemix‐adjusted outcomes were analysed in models that included random‐effects for centre, surgeon and anaesthetist. All cardiac surgical operations for which the EuroSCORE model is appropriate were included, and the primary outcome was in‐hospital death up to three months postoperatively. A total of 110 769 cardiac surgical procedures conducted between April 2002 and March 2012 were studied, which included 127 consultant surgeons and 190 consultant anaesthetists. The overwhelming factor associated with outcome was patient risk, accounting for 95.75% of the variation for in‐hospital mortality. The impact of the surgeon was moderate (intra‐class correlation coefficient 4.00% for mortality), and the impact of the anaesthetist was negligible (0.25%). There was no significant effect of anaesthetist volume above ten cases per year. We conclude that mortality after cardiac surgery is primarily determined by the patient, with small but significant differences between surgeons. Anaesthetists did not appear to affect mortality. These findings do not support public disclosure of cardiac anaesthetists' results, but substantially validate current UK cardiac anaesthetic training and practice. Further research is required to establish the potential effects of very low anaesthetic caseloads and the effect of cardiac anaesthetists on patient morbidity.     

Substance misuse amongst anaesthetists in the United Kingdom and Ireland. The results of a study commissioned by the Association of Anaesthetists of Great Britain and Ireland

Three hundred and four departments of anaesthesia in UK and Ireland were sent questionnaires about alcohol and drug abuse in anaesthetists over the preceding 10-year period. Information was sought on the nature and extent of substance problems, their presentation and management. The survey achieved a high response rate of 71.7% and a total of 130 cases were reported, of whom 34.6% were consultants and 43.2% were trainees. Over 50% of respondents felt a lack of confidence in dealing with alcohol or drug misuse amongst colleagues. The results of this survey demonstrate that over one anaesthetist per month has presented with significant alcohol or drug misuse in the UK and Ireland over the last 10 years. It is important that those with management responsibilities for departments of anaesthesia are aware that such problems exist and are likely to impact on the professional ability and health of the affected individual. The Working Party on Substance Abuse at the Association of Anaesthetists has recently published guidance in the management of these problems. A case is made for increasing awareness in this sensitive subject to enable early recognition and treatment of an anaesthetist who is misusing alcohol and drugs since intervention can be effective.     

Estimating the time needed for induction of anaesthesia and its importance in balancing anaesthetists' and surgeons' waiting times around the start of surgery

After the anaesthetist has induced anaesthesia, it is desirable that the surgeon is present and ready to start surgery, otherwise the team needs to wait for the surgeon. From another perspective, however, the surgeon does not necessarily wish to be present from the start of induction, since that process can take a variable time and the surgeon might be otherwise occupied in productive activity rather than waiting for the patient to be ready. Waiting times in the morning can therefore be a source of constant friction between anaesthetists and surgeons. In this prospective study we used the data from 718 first cases of the day, during a 4-week study period at two university hospitals, to develop a simple spreadsheet-based method to analyse the interaction of anaesthesia and surgical start time, anaesthesia technique and the probability of waiting time for anaesthetist or surgeon, respectively. This method can be used to determine the best surgical or anaesthesia start time for each case, so that the waiting time for anaesthetists and surgeons can be minimised.     

The anaesthesia consult clinic: does it matter which anaesthetist sees the patient?

Purpose

The objectives of this multicentre survey were: first to ascertain whether the preoperative evaluation performed by anaesthetists in the preadmission anaesthesia consultation clinic (PACC) is influenced by the knowledge that they will or will not be the patient’s attending anaesthetist; and second to determine the agreement among anaesthetists with regard to investigations requested.

Methods

A postal survey was designed in two different versions, equal numbers of which were sent to 522 anaesthetists in 39 Canadian hospitals. The anaesthetists contacted were asked to consider how they would investigate two hypothetical patients in a PACC. One version of the survey stated that they would be the attending anaesthetist for the first patient, but not for the second patient (group A). In the second version the situation was reversed (group B).

Results

A total of 281 eligible replies were received. For each of the two patients the decision to order an echocardiogram, cardiac stress test, arterial blood gas analysis, pulmonary function tests, or internal medicine referral was not affected by the knowledge that the respondent would or would not be the patient’s attending anaesthetist. Within each of the two groups there was very little consensus with regard to the ordering of laboratory tests.

Conclusion

The extent of investigation in the PACC scenarios was not affected by knowledge of whether or not the consulting anaesthetist would be the attending anaesthetist in the operating room. However, there was minimal agreement among anaesthetists concerning the preoperative evaluation of the patients, regardless of who would be the anaesthetist on the day of operation. Efficiency in preoperative evaluation could be increased if anaesthetists saw their own patients in the PACC, or if clinical guidelines for patient assessment were introduced by departments.     

Mental disorder in pregnancy and the early postpartum

Perinatal mental illness is common, affecting up to 20% of women, but remains under-recognised and under-diagnosed. It may have adverse effects on pregnancy and neonatal outcomes, and mental disorder remains one of the leading causes of maternal death in the UK. Women with mental ill health face difficult decisions in balancing risks and benefits of treatment. Stigma related to mental disorder may lead to non-engagement with maternity care. Some disorders bring specific challenges for anaesthetists working in maternity settings and it is vital that anaesthetists have knowledge of these disorders so they may offer care which is sensitive and appropriate.     

Resuscitation of the newborn

Neonatal resuscitation can feel daunting to the anaesthetist as it differs to all other forms of resuscitation due to the physiological changes which occur at birth. Although not routine, anaesthetic input may be required in those cases requiring resuscitation, and here we aim to familiarize anaesthetists with the principles and guidance for neonatal resuscitation in the UK.     

Neonatal resuscitation in the delivery room. What role does the anesthetist play?]

Neonatal resuscitation in the delivery room of small obstetric units is problematic because of the lack of on-site personnel with adequate training and experience. In large university hospitals this task is usually fulfilled by neonatologists who are present 24 h/day. However, in medium-sized and small obstetric units neonatal resuscitation is performed by a variety of professionals: paediatricians, obstetricians, anaesthetists, midwives, nurses, and nurse anaesthetists. The degree of responsibility and involvement of the anaesthesia specialist in the resuscitation of the newborn in Switzerland is unknown, and therefore an investigation was conducted. METHOD. After a telephone inquiry at all the hospitals in Switzerland, a total of 175 obstetric units were identified. A questionnaire with items regarding organisation, responsibilities, and the extent of involvement of the anaesthesia department of the particular hospital was sent to each of the appropriate anaesthetists. RESULTS. Of the 175 questionnaires, 163 (93%) were returned; 14 could not be analysed (5 were sent to hospitals where there was in fact no obstetric unit and 9 were sent to anaesthetists who shared responsibilities for one unit). In 1988, 76,505 babies were born in Switzerland; two-thirds of these were delivered in hospitals with an annual birth rate of less than 600 births per year. Of the 149 questionnaires that were eligible for further analysis, 118 (79%) documented participation of the anaesthetic team in the resuscitation of the newborn. However, only 22% of these departments had an official contract with the hospital administration. Ninety-nine per cent of all responders agreed that every anaesthetist should have the knowledge--both theoretical and practical--to resuscitate a newborn infant. However, reservations were expressed on how to acquire and how to maintain this competence. The initial evaluation of the newborn was done by an anaesthetist in 3% (2250/76,505) of all deliveries in Switzerland in 1988; 1.2% (882/76,505) of these babies needed bag-and-mask ventilation and in 0.4% (308/76,505) endotracheal intubation was performed by the anaesthetist. Proceeding on the assumption that 5% of all newborns need some sort of resuscitation immediately after birth, it is estimated that in 1988 approximately one-third of resuscitations were performed by anaesthetists. It is therefore concluded that anaesthetists play an important role in the resuscitation of newborns in Switzerland.     

Occupational hazards to reproduction and health in anaesthetists and paediatricians

A mail questionnaire was sent to Finnish anaesthetists and paediatricians to evaluate the risks of reproductive, teratogenic and health complications related to the professions. The incidence of diagnosed spontaneous miscarriages in anaesthetists' families was 10.2% of all pregnancies and it was 13.2% in paediatricians' families. Smoking seemed to increase markedly the incidence of spontaneous miscarriages, which was 22.9% in smoking female anaesthetists and 17.2% in smoking female paediatricians. The gestation times in cases of both full-term pregnancies and miscarriages were shorter in the anaesthetist group than those in the paediatrician group. Congenital abnormalities appeared at an equal rate in both anaesthetist and paediatrician groups, but strikingly, there were nine musculoskeletal abnormalities in the anaesthetists' children compared to no such defects in paediatricians' children. Serious diseases occurred at low frequencies, but three cases of hepatic jaundice and three cases of viral myocarditis in anaesthetists indicate possible infectious hazards to health in anaesthetic work. Different infectious diseases to the respiratory and urinary tracts were commonest among paediatricians. Cancer was not reported in the anaesthetist group. The study does not indicate that gas pollution in operating rooms is harmful to the personnel.     

An evaluation of the laryngeal mask airway during routine paediatric anaesthesia

During a six week period, all anaesthetists at the Royal Hospital for Sick Children, Glasgow were asked to complete a questionnaire whenever a laryngeal mask airway (LMA) was used. Seniority of anaesthetist, age of patient, anaesthetic technique, technique of LMA insertion, ease of LMA insertion, and any problems encountered either during LMA insertion, or during induction, maintenance, and recovery from anaesthesia were documented. Complete data were obtained from 211 patients aged 5 weeks to 15 years. Ninety-six children were anaesthetized by consultant paediatric anaesthetists, and 115 by trainees. LMA insertion was successful at the first attempt in 86% of all cases, achieved with some difficulty in 11% of cases, and failed or its use was abandoned in 6 cases (3%). Difficulties other than with LMA placement per se occurred in 11% of cases during induction of anaesthesia. Seniority of anaesthetist and choice of anaesthetic agent influenced neither the success rate of insertion nor the frequency of other difficulties encountered during induction of anaesthesia. Significantly fewer problems were encountered at LMA removal if this was done during deep anaesthesia compared with removal when protective reflexes were present (P < 0.05).     

Anaesthetists' attitudes to intraoperative death

BACKGROUND AND OBJECTIVES: A recent survey in the British Medical Journal reported the attitudes of orthopaedic surgeons towards the intraoperative death of a patient. Several replies to this article were from anaesthetists, who pointed out that other staff might be affected by 'death on the table'. We designed a questionnaire survey to assess the attitudes of anaesthetists, concerning intraoperative death. METHODS: Three hundred anonymized questionnaires were distributed to 12 anaesthetic departments throughout England. RESULTS: Two hundred and fifty-one replies were received (84% response rate); 92% of respondents had experienced an intraoperative death, the majority of deaths being expected (60%) and non-preventable (77%), occurring mainly during emergency surgery (80%), particularly involving vascular surgery (41% of cases); 87% had administered another general anaesthetic in the following 24 h, most without their professional ability being compromised (77%). CONCLUSIONS: This survey shows that anaesthetists are highly likely to experience intraoperative death, the consequences of which can be extremely stressful. Although the majority of anaesthetists (71%) agreed that it was reasonable for medical staff not to take part in operations for 24 h after an intraoperative death, fewer (25%) thought the proposal practicable. Nevertheless, all departments should provide for the discontinuation of further operations, if the circumstances require it. Consideration should be given by all departments of anaesthesia towards the prevention of intraoperative death, and the management of its aftermath, including the provision of support for psychologically traumatized staff.     

Treatment of ventricular fibrillation during anaesthesia in an anaesthesia simulator

Background : To evaluate treatment of ventricular fibrillation (VF) occurring during anaesthesia and the use of a full–scale simulator, 80 anaesthetists in teams of two were attending a training session in the simulator Sophus.
Methods : The sessions were recorded on videotape and reviewed with the anaesthetists afterwards. Time of treatment and the sequence were registered.
Results : Onset time for VF was the starting point. Most of the subjects changed respiratory settings. Four teams did not change inspiratory oxygen and 17 teams did not turn off the vaporiser. Cardiac compression was initiated by all teams. DCdefibrillation was not used by two teams, with 38 of 40 teams defibrillating once, 37 twice and 29 teams three times. Adrenaline was administered by 30 of 40 teams.
Conclusion : There was very little consistency among the teams regarding treatment for VF according to accepted algorithms. An anaesthesia simulator could be a tool for training and it is a safe way of demonstrating for the anaesthetist that certain treatment algorithms and behaviour during critical incidents are the most effective.     

Pre-operative screening: criteria for referring to anaesthetists

Nurses assess patients pre-operatively using screening questionnaires and locally-developed protocols. Our objectives were to determine which questions might identify patients who should be seen by an anaesthetist before the day of surgery. A review of the literature and a preliminary questionnaire to establish questions to be tested was followed by a modified, two-round Delphi questionnaire to determine the level of agreement by anaesthetists. There was agreement for referring patients who gave a positive response to questions that query: restricted exercise tolerance; previous anaesthetic problems; family history of anaesthetic problem; pathology affecting neck movement; angina; arrhythmia; heart failure; asthma; epilepsy; insulin-dependent diabetes mellitus; liver disease and unspecified kidney disease. There was equivocal agreement on questions that report a myocardial infarction over one year ago, cerebrovascular accident, non insulin-dependent diabetes mellitus and thyroid disease. Nurses should use these criteria during pre-operative assessment to decide the timing of evaluation by an anaesthetist.     

Anaesthetic management of emergency caesarean section in a patient with Noonan's syndrome--case report and literature review

Patients with Noonan's syndrome present a multiplicity of challenges to the anaesthetist, particularly with regard to cardiovascular, spinal, and airway abnormalities. Anaesthetist may have to deal with an increasing number of these patients presenting to anaesthesia departments requesting analgesia and anaesthesia for surgery of labour. Early detection and planing between obstetricians, midwives and anaesthetists will help successful management of these patients. Alternative methods of management should be discussed fully with patients. Regional anaesthesia, although may be difficult in these patients, is a safe alternative compared to expensive general anaesthesia.     

Laptops and smartphones in the operating theatre - how does our knowledge of vigilance, multi-tasking and anaesthetist performance help us in our approach to this new distraction?

There has been no research performed concerning the effects of the use of laptops and smartphones in the operating theatre on anaesthetist performance, yet these devices are now in frequent use. This article explores the implications of this phenomenon. The cognitive and environmental factors that support or detract from vigilance and multi-tasking are explored and core anaesthetic literature on the nature of anaesthetic work and operating theatre distractions is reviewed. Experienced anaesthetists are skilled at multi-tasking while maintaining situational awareness, but there are limits. Noise, interruptions and emotional arousal are detrimental to the cognitive performance of anaesthetists. While limited reading during periods of low task load may not reduce vigilance, computer use introduces text-based activities that are more interactive and potentially more distracting. All anaesthetists need to be mindful of the limits to the human attention span which requires observation and limiting distractions. Trainees have less experience and less 'attentional' safety margin, so should avoid adding additional distractions such as discretionary use of laptops or smartphones to their operating theatre work. We provide recommendations for future research on the specific advantages and disadvantages of pervasive computing in the operative theatre.     

Anaesthetic equipment in low and low-middle income countries

There is a discrepancy between healthcare need and the ability to provide safe anaesthesia in low/low-middle income countries (LMICs). There is a shortage of medically trained anaesthetists. Most anaesthetics are provided by non-physician anaesthetists who may not have studied the core sciences underpinning anaesthesia, but are clinically very competent. Poor infrastructure is common, such as a shortage of piped medical gases and critical care beds. Safe anaesthesia depends on effective technology, and on consumables such as cannulae, and drugs, all of which are under-provided resources in LMICs. Much of the equipment used in the developed world is unsuitable for use in LMICs. Anaesthetic equipment used in LMICs, such as draw-over breathing systems and oxygen concentrators, may be unfamiliar to developed world anaesthetists. Cleaning and maintenance of equipment is usually the responsibility of the anaesthetist, who needs a good understanding of how it works.

Man-machine interface: The position of the anaesthetic machine in the operating room

The question posed for this study was: “While holding a watching brief during an uneventful intra-abdominal surgical procedure do anaesthetists adopt the same position in the operating room with reference to the patient’s head and ’anaesthetic machine’ and, if they do, what is it?” A study of the relative positions of the patient, the anaesthetist, and the “anaesthetic machine” during routine laparotomy showed great variation. The implication was that there was also great variation in the amount of movement necessary by the anaesthetist if the same amount of information was to be obtained with the same frequency. The significance of this with reference to the quality of patient care is discussed. The role of changes in apparatus and the declared need for this by anaesthetists is mentioned and recommendations regarding the visual acquisition of data during anaesthesia are made.
