Mixed methods analysis of factors influencing change in clinical behaviours of non-physician anaesthetists in Kenya following obstetric anaesthesia training.

Maternal mortality rates in low-middle income countries remain high, with sub-Saharan Africa accounting for two-thirds of global maternal deaths. Inadequate staff training is one of the main contributors to anaesthesia-related deaths and the Association of Anaesthetists developed the Safe Anaesthesia from Education course in collaboration with the World Federation of Societies of Anaesthesiologists to address this training gap. We aimed to evaluate the impact of this course among Kenyan participants. Mixed methodologies and secondary analyses of anonymised data were used to study translation of learning into practice. In total, 103 participants from 66 facilities who attended courses between 2016 and 2017 were analysed. Ninety (87%) participants who were followed up completed knowledge tests. Baseline median (IQR [range]) knowledge test score was 41 (37-43 [21-46]). There was a significant improvement in median (IQR [range]) knowledge test score immediately post-course (43 (41-45 [33-48]); p < 0.001) which was sustained at 3-6 month follow-up (43 (41-45 [32-50]); p < 0.001 compared with baseline). Eighty-four of the 103 participants were observed in their workplace and capability, opportunity and motivation-behaviour framework was used to study the barriers and facilitators to practice change. Psychological capability and reflective motivation were the main factors enabling positive behaviour change such as team communication and pre-operative assessment, whereas physical and social opportunity accounted for the main barriers to behaviours such as performing the surgical safety checklist. Our study demonstrates that the Safe Anaesthesia from Education obstetric course is relevant in the low-resource setting and may lead to knowledge translation in clinical practice.

Safety, complications and clinical outcome after ultrasound-guided paravertebral catheter insertion for rib fracture analgesia: a single-centre retrospective observational study.

Rib fractures are associated with significant morbidity and mortality. Ultrasound-guided thoracic paravertebral catheter insertion has been described for the management of pain secondary to rib fractures. We conducted a retrospective observational study of all patients with rib fractures who had a paravertebral catheter inserted for analgesia provision over a 4-year period. Data from the Trauma Audit and Research Network were used to compare patients with rib fractures who were managed with paravertebral catheters to those managed with systemic analgesia. A total of 314 consecutive paravertebral catheters were inserted in 290 patients. Five (1.9%) catheters were removed due to ineffective analgesia. Other minor complications occurred in three cases (0.96%). The proportion of rib fracture patients managed with paravertebral catheters increased from 31/200 (15.5%) in the first year of study to 81/168 (48.2%) in the fourth; over this time-period the observed:predicted mortality ratio fell from 1.04 to 0.66. Proportional hazard regression with and without propensity score matching demonstrated a reduction in mortality associated with paravertebral catheter use, but this became statistically non-significant when time-dependent analysis was used. Paravertebral catheters are a safe and effective technique for rib fracture analgesia; however, our data were insufficient to demonstrate any improvement in mortality.

A mixed-methods evaluation of the Association of Anaesthetists of Great Britain and Ireland Uganda Fellowship Scheme.

The Association of Anaesthetists of Great Britain and Ireland and the then Uganda Society of Anaesthesia established the Uganda Fellowship Scheme in 2006, to provide scholarships to encourage doctors to train in anaesthesia in Uganda. We conducted an evaluation of this programme using online questionnaires and face-to-face semi-structured interviews with trainees who received scholarships, as well as with senior surgeons and anaesthetists. Focus group discussions were held to assess changes in attitudes towards anaesthesia over the last 10 years. Interviews were recorded, transcribed and analysed using the constant comparative method. A total of 54 Ugandan doctors have received anaesthesia scholarships since 2006 (median funding per trainee (IQR [range]) £5520 (£5520-£6750 [£765-£9000]). There has been a four-fold increase in the number of physician anaesthetists in Uganda during this time. All those who received funding remain in the region. The speciality of anaesthesia is undergoing a dramatic transformation led by this group of motivated young anaesthetists. There is increased access to intensive care, and this has allowed surgical specialities to develop. There is greater understanding and visibility of anaesthesia, and the quality of education in anaesthesia throughout the country has improved. The Uganda Fellowship Scheme provided a relatively small financial incentive to encourage doctors to train as anaesthetists. Evaluation of the project shows a wide-ranging impact that extends beyond the initial goal of simply improving human resource capacity. Financial incentives combined with strong 'north-south' links between professional organisations can play an important role in tackling the shortage of anaesthesia providers in a low-income country and in improving access to safe surgery and anaesthesia.

Lifebox pulse oximeter implementation in Malawi: evaluation of educational outcomes and impact on oxygen desaturation episodes during anaesthesia.

Pulse oximetry is an essential monitor for safe anaesthesia but is often not available in low-income countries. The aim of this study was to determine whether the introduction of pulse oximetry with training was feasible and could reduce the incidence of oxygen desaturation during anaesthesia in a low-income country. Pulse oximeters were donated, with training, to 83 non-physician anaesthetists in Malawi. Knowledge was tested immediately before and after training and at follow-up. Providers were asked to record the lowest peripheral oxygen saturation (SpO2 ) for the first 100 cases anaesthetised after training. The primary clinical outcome was the proportion of cases with an oxygen desaturation event (SpO2 < 90%). Seventy-seven of 83 (93%) participants completed all pre- and post-training tests. Pulse oximetry knowledge improved after training from a median (IQR [range]) score of 39 (37-42 [28-48]) to 44 (42-46 [35-50]) and this knowledge was maintained for 8 months (p < 0.001). Oxygen saturation data and provider responses were recorded for 4772 cases. The proportion of oxygen desaturation episodes decreased from 17.2% to 6.5%, representing a 36% reduction in the odds of an oxygen desaturation event in the second 50 cases compared with the first 50 (OR 0.64, 95%CI 0.50-0.82, p < 0.001). We conclude that donation of pulse oximeters, with training, in Malawi was feasible, improved knowledge and reduced the incidence of oxygen desaturation events.

Implementation of the WHO Surgical Safety Checklist and surgical swab and instrument counts at a regional referral hospital in Uganda - a quality improvement project.

The World Health Organization (WHO) Surgical Safety Checklist is a cost-effective tool that has been shown to improve patient safety. We explored the applicability and effectiveness of quality improvement methodology to implement the WHO checklist and surgical counts at Mbarara Regional Referral Hospital in Uganda between October 2012 and September 2013. Compliance rates were evaluated prospectively and monthly structured feedback sessions were held. Checklist and surgical count compliance rates increased from a baseline median (IQR [range]) of 29.5% (0-63.5 [0-67.0]) to 85.0% (82.8-87.5 [79.0-93.0]) and from 25.5% (0-52.5 [0-60.0]) to 83.0% (80.8-85.5 [69.0-89.0]), respectively. The mean all-or-none completion rate of the checklist was 69.3% (SD 7.7, 95% CI [64.8-73.9]). Use of the checklist was associated with performance of surgical counts (p value < 0.001; r(2) = 0.91). Pareto analysis showed that understaffing, malfunctioning and lack of equipment were the main challenges. A carefully designed quality improvement project, including stepwise incremental change and standardisation of practice, can be an effective way of improving clinical practice in low-income settings.

Incidence of hypoxia and related events detected by pulse oximeters provided by the Lifebox Foundation in the maternity unit at Sylvanus Olympio University Teaching Hospital, Togo.

In recent decades anesthesia safety has not been improved in low-income countries. This prospective audit describes the incidence of hypoxia and related events detected among a cohort of patients undergoing surgery in the maternity unit at Sylvanus Olympio University Teaching Hospital, Togo, West Africa, by using pulse oximeters donated by the Lifebox Foundation. The Lifebox oximeter enables early detection of hypoxia for patients undergoing surgery before irreversible damage occurs. Pulse oximetry is cost-effective intervention and should be more accessible in all operating rooms of this type.

Evaluation of a large-scale donation of Lifebox pulse oximeters to non-physician anaesthetists in Uganda.

Pulse oximetry is widely accepted as essential monitoring for safe anaesthesia, yet is frequently unavailable in resource-limited settings. The Lifebox pulse oximeter, and associated management training programme, was delivered to 79 non-physician anaesthetists attending the 2011 Uganda Society of Anaesthesia Annual Conference. Using a standardised assessment, recipients were tested for their knowledge of oximetry use and hypoxia management before, immediately following and 3-5 months after the training. Before the course, the median (IQR [range]) test score for the anaesthetists was 36 (34-39 [26-44]) out of a maximum of 50 points. Immediately following the course, the test score increased to 41 (38-43 [25-47]); p < 0.0001 and at the follow-up visit at 3-5 months it was 41 (39-44 [33-49]); p = 0.001 compared with immediate post-training test scores, and 75/79 (95%) oximeters were in routine clinical use. This method of introduction resulted in a high rate of uptake of oximeters into clinical practice and a demonstrable retention of knowledge in a resource-limited setting.

Surgical safety checklists: do they improve outcomes?

The concept of using a checklist in surgical and anaesthetic practice was energized by publication of the WHO Surgical Safety Checklist in 2008. It was believed that by routinely checking common safety issues, and by better team communication and dynamics, perioperative morbidity and mortality could be improved. The magnitude of improvement demonstrated by the WHO pilot studies was surprising. These initial results have been confirmed by further detailed work demonstrating that surgical checklists, when properly implemented, can make a substantial difference to patient safety. However, introducing surgical checklists is not as straightforward as it seems, and requires leadership, flexibility, and teamwork in a different way to that which is currently practiced. Future work should be aimed at ensuring effective implementation of the WHO Surgical Safety Checklist, which will benefit our patients on a global scale.

Improving surgical safety globally: pulse oximetry and the WHO Guidelines for Safe Surgery.

Access to safe surgery should be considered as part of the basic human right for health, but unfortunately, this ideal is far from being reached in many low-income countries. Pulse oximetry is recommended as a minimum standard of monitoring by all anesthesia organizations that have set standards, yet around 78,000 operating theaters worldwide lack this essential monitor. The WHO Safe Surgery Saves Lives Program has identified evidence-based guidelines for safe surgery that are applicable in any setting, and the Global Pulse Oximetry Program will help improve access to pulse oximetry in countries where it is not available. However, these initiatives are just a start; capacity, infrastructure, trained healthcare providers and access to essential drugs, and equipment for anesthesia and surgery need to become a public health priority in many low-income countries.

The portable Glostavent: a new anaesthetic machine for use in difficult situations.

A portable version of the Glostavent anaesthetic machine is described in which recent developments in draw-over technology are incorporated into a traditional draw-over anaesthetic system. The additional features include a more efficient reservoir and an improved vaporiser which have enhanced the performance and versatility. The portable Glostavent weighs less than 10 kg and is transported in a container the size of a small suitcase. It can be used to provide inhalational anaesthesia safely and economically in situations where there are no support facilities. It is ideal for use in battlefield or disaster situations and in isolated hospitals in disadvantaged regions of the world.

Global oximetry: an international anaesthesia quality improvement project.

Pulse oximetry is mandatory during anaesthesia in many countries, a standard endorsed by the World Health Organization 'Safe Surgery Saves Lives' initiative. The Association of Anaesthetists of Great Britain and Ireland, the World Federation of Societies of Anaesthesiologists and GE Healthcare collaborated in a quality improvement project over a 15-month period to investigate pulse oximetry in four pilot sites in Uganda, Vietnam, India and the Philippines, using 84 donated pulse oximeters. A substantial gap in oximeter provision was demonstrated at the start of the project. Formal training was essential for oximeter-naïve practitioners. After introduction of oximeters, logbook data were collected from over 8000 anaesthetics, and responses to desaturation were judged appropriate. Anaesthesia providers believed pulse oximeters were essential for patient safety and defined characteristics of the ideal oximeter for their setting. Robust systems for supply and maintenance of low-cost oximeters are required for sustained uptake of pulse oximetry in low- and middle-income countries.

Paediatric anaesthesia in developing countries.

Each year millions of children undergo surgery in the developing world with inadequate facilities, equipment and drugs. In many hospitals, anaesthesia is largely dependent on the availability of ketamine. Application of well-established clinical techniques, particularly for postoperative pain control, would relieve unnecessary suffering in children. Improvements in peri-operative care are required by investment in health systems and training.

Specialist surgery in the developing world: luxury or necessity?

Patients suffering from conditions requiring specialist intervention cannot obtain treatment when facilities do not exist locally. Specialist visiting teams in a number of surgical disciplines have attempted to address these issues in collaboration with local clinicians. These interventions require careful planning and communication to achieve optimum results. Several teams have been successful in building long-term relationships that have lead to important clinical developments in the local country.

Anaesthesia services in developing countries: defining the problems.

We describe the use of a questionnaire to define the difficulties in providing anaesthesia in Uganda. The results show that 23% of anaesthetists have the facilities to deliver safe anaesthesia to an adult, 13% to deliver safe anaesthesia to a child and 6% to deliver safe anaesthesia for a Caesarean section. The questionnaire identified shortages of personnel, drugs, equipment and training that have not been quantified or accurately described before. The method used provides an easy and effective way to gain essential data for any country or national anaesthesia society wishing to investigate anaesthesia services in its hospitals. Solutions require improvements in local management, finance and logistics, and action to ensure that the importance of anaesthesia within acute sector healthcare is fully recognised. Major investment in terms of personnel and equipment is required to modernise and improve the safety of anaesthesia for patients in Uganda.

Impact of the European Working Time Directive on the training of paediatric anaesthetists.

The European Working Time Directive and the New Deal have decreased the number of hours worked by anaesthetic trainees. We implemented the Working Time Directive in May 2004 and evaluated the effect of its implementation on training. During two 6-month periods, one before and one after the change, we determined the number of operating lists undertaken by each Specialist Registrar in Anaesthesia. After implementation of the Working Time Directive, the mean number of lists performed by Specialist Registrars decreased from 24 to 21 lists per registrar per month, a 13% decrease. Exposure to subspecialty lists was the same in both periods, but this was at the expense of general lists and those in remote locations. We conclude that the Working Time Directive has had a measurable impact on the training of paediatric anaesthetists, but that the significance of this change for clinical practice has not yet been measured.

Assessment of a point-of-care test for paracetamol and salicylate in blood.

BACKGROUND: Paracetamol and salicylate are commonly taken in acute overdose. Clinicians have a low threshold for excluding the presence of these two drugs, by ordering laboratory tests in any patient suspected of ingesting an overdose or with an altered mental state. AIM: To test the effectiveness of a new point of care test that qualitatively detects paracetamol and salicylate in blood and to examine the potential time saved by its use. DESIGN: Prospective multicentre trial. METHODS: The new test was compared with laboratory analysis in a routine blood sample taken from patients presenting to emergency departments with suspected overdose. RESULTS: The test had sensitivities of 98.5% and 88.5%, and specificities of 74.7% and 92%, for paracetamol and salicylate, respectively, at cut-off levels of 25 mg/l and 100 mg/l, respectively The point of care test results were available 2 h before the laboratory result. DISCUSSION: This point-of-care test could be used to rule out an overdose with either of these two drugs, and could thus lead to earlier clinical decisions for suspected overdose patients. Recommendations have been made following this trial that the cut-off value for paracetamol should be reduced from 25 mg/l to 12.5 mg/l in order to increase its usefulness. To prevent the test being misread, we also suggest that each device should be embossed to remind users that the presence of a line indicates there is no drug present.

Lidocaine in the treatment of status epilepticus.

Intravenous lidocaine has the potential to control seizures. This article reviews the available evidence related to lidocaine's efficacy and clarifies its potential role in the management of status epilepticus (SE). Although there are no large, double-blind, placebo-controlled studies of lidocaine's efficacy in SE, numerous case reports and case series support its use. Most of the reported cases involve patients who were refractory to multiple antiseizure medications. Additional support for lidocaine's efficacy in SE comes from the pediatric literature, where lidocaine has been very effective in controlling SE in neonates who have not responded to barbiturates. Initial lidocaine doses used to stop seizures have ranged from 1 to 3 mg/kg. Most reports recommend a maintenance infusion of lidocaine after initial termination of SE, and a continuous infusion is almost universally recommended for neonates. Toxicity from a 1.5-2.0 mg/kg dose of lidocaine for the control of SE is rare; the authors found only 1 case of a possible side effect at that dose. The article provides a 5-step approach to treating SE that includes lidocaine.
