Improving Access to Safe Anesthetic Care in Rural and Remote Communities in Affluent Countries

Undergraduate Anesthesia Skills for a Global Surgery Agenda: Students' Self-Reported Competence

BACKGROUND

Safe anesthesia is imperative for the Global Surgery agenda and Sustainable Development Goal 3. Due to a shortage of specialists in South Africa (SA), anesthetic services are often provided by nonspecialist doctors, often newly qualified and frequently without immediate supervision. The burden of disease in the developing world demands fit-for-purpose, day-one medical graduates. Although undergraduate anesthesia training is mandatory for medical students in SA, no outcomes are specified, and these are decided autonomously at each medical school. This study describes the current self-perceived anesthetic competence of medical students in SA as a needs assessment directed at achieving the goals of Global Surgery in SA and other developing countries.

METHODS

In this cross-sectional observational study, 1689 students (89% participation rate), representing all medical schools in SA, rated their self-perceived competence at graduation in 54 anesthetic-related Likert scale items in 5 themes: patient evaluation, patient preparation for anesthesia, practical skills performance, administration of anesthesia, and the management of intraoperative complications. Medical schools were divided into clusters A (≥25 days of anesthetic training) and B (<25 days). Descriptive statistics, Fisher exact test, and a mixed-effects regression model were used in the statistical analysis.

RESULTS

Students felt more prepared for history-taking and patient examination than for managing emergencies and complications. The self-perceived competence of students at cluster A schools was higher across all 54 items and all 5 themes. The same was observed for general medical skills and skills relating to maternal mortality in SA.

CONCLUSIONS

Time-on-task, capacity for repetition, and student maturity might have impacted self-efficacy and should be considered in curriculum development. Students felt less prepared for emergencies. Focused training and assessment aimed at emergency management should be considered. Students did not feel competent in general medical areas, in which anesthetists are experts, including resuscitation, fluid management, and analgesia. Anesthetists should take ownership of this training at the undergraduate level. Cesarean delivery is the most performed surgical procedure in sub-Saharan Africa. The Essential Steps in Managing Obstetric Emergencies (ESMOE) program was designed for internship training but can be introduced at undergraduate level. This study suggests that curriculum reform is required. The achievement of an agreed-upon set of standardized national undergraduate anesthetic competencies may ensure fit-for-purpose practitioners. Undergraduate and internship training should align to form part of a continuum of basic anesthetics training in SA. The findings of this study might benefit curriculum development in other regions with similar contexts.

A survey of Canadian specialist anesthesiologists and family practice anesthetists: rural operating room use, a mixed model of care, and mentoring

PURPOSE

The aim of this project was to collect data on the delivery of anesthesia in Canada. Specifically, our goal was to increase knowledge by identifying provider demographics and different models of anesthesia delivery, and to explore relationships among specialist anesthesiologists (SAs) and family practice anesthetists (FPAs) with a focus on mentoring.

METHODS

An online questionnaire was circulated to SAs and FPAs holding membership with the Canadian Anesthesiologists' Society or the Society of Rural Physicians of Canada. A total of 274/2,578 individuals completed the survey (170 SAs and 104 FPAs), providing a response rate of 10.6%. The survey included questions about demographics, anesthesia training, anesthesia resources, models of care, and mentoring relationships.

RESULTS

Three major themes emerged from the data: 1) FPAs and rural operating rooms are underused resources as 65% (64/98) of FPAs reported having capacity to increase their individual volume of anesthesia services and 41% (40/98) thought capacity existed within their hospital to increase the volume of surgery; 2) 20 hospitals employed a mixed model of anesthesia care whereby SAs and FPAs worked collectively within the same site; providers working within this model reported high levels of satisfaction and independence; 3) most SAs and FPAs perceived a benefit to mentoring and were interested in participating in a mentoring program.

CONCLUSION

This survey shows perceived capacity to expand surgical services in rural areas, a precedent for a mixed SA-FPA model of anesthesia delivery at the same site, and desire for anesthesia providers to engage in mentoring. Such options should be considered to strengthen the physician-led anesthesiology profession in Canada.

The new Diploma of Rural Generalist Anaesthesia: Supporting Australian rural and remote communities

In 2023, a Diploma of Rural Generalist Anaesthesia (DipRGA) was implemented across Australia. Developed collaboratively by the Australian and New Zealand College of Anaesthetists (ANZCA), the Australian College of Rural and Remote Medicine (ACRRM) and the Royal Australian College of General Practitioners (RACGP), the 12-month qualification is completed during or following ACRRM or RACGP Rural Generalist Fellowship training. Focused on the needs of rural and remote communities for elective and emergency surgery, maternity care, resuscitative care for medical illness or injury, and stabilisation for retrieval, the DipRGA supports rural generalist anaesthetists working within collaborative teams in geographically isolated settings. The goal is a graduate who can anaesthetise American Society of Anesthesiologists physical status class 1, 2 and stable 3 patients for elective surgery, provide obstetric anaesthesia and analgesia, anaesthetise paediatric patients and undertake advanced crisis care within their scope of practice. Crucially, they also recognise both limitations of their skills and local resources available when considering whether to provide care, defer, refer or transfer patients. DipRGA curriculum design commenced by adapting the ANZCA specialist training curriculum with consideration of the training approach of both the ACRRM and the RACGP, particularly the rural and remote context. Curriculum content is addressed in seven entrustable professional activities supported by workplace-based assessments and multisource feedback. Trainees are supervised by rural generalist anaesthetists and specialist anaesthetists, and complete flexible learning activities to accommodate geographical dispersion. Standardised summative assessments include an early test of knowledge and an examination, adapted from the ACRRM structured assessment using multiple patient scenarios.

Shared Decision-Making in Acute Pain Services

PURPOSE OF REVIEW

The implementation of shared decision-making (SDM) in acute pain services (APS) is still in its infancies especially when compared to other medical fields.

RECENT FINDINGS

Emerging evidence fosters the value of SDM in various acute care settings. We provide an overview of general SDM practices and possible advantages of incorporating such concepts in APS, point out barriers to SDM in this setting, present common patient decisions aids developed for APS and discuss opportunities for further development. Especially in the APS setting, patient-centred care is a key component for optimal patient outcome. SDM could be included into everyday clinical practice by using structured approaches such as the "seek, help, assess, reach, evaluate" (SHARE) approach, the 3 "MAking Good decisions In Collaboration"(MAGIC) questions, the "Benefits, Risks, Alternatives and doing Nothing"(BRAN) tool or the "the multifocal approach to sharing in shared decision-making"(MAPPIN'SDM) as guidance for participatory decision-making. Such tools aid in the development of a patient-clinician relationship beyond discharge after immediate relief of acute pain has been accomplished. Research addressing patient decision aids and their impact on patient-reported outcomes regarding shared decision-making, organizational barriers and new developments such as remote shared decision-making is needed to advance participatory decision-making in acute pain services.

The anesthesia workforce in Canada: a methodology to identify physician anesthesia providers using health administrative data

BACKGROUND

Safe and timely anesthesia services are an integral component of modern health care systems. There are, however, increasing concerns about the availability of anesthesia services in Canada. Thus, a comprehensive approach to assess the capacity of the anesthesia workforce to provide service is a critical need. Data regarding the anesthesia services provided by specialists and family physicians are available through the Canadian Institute for Health Information (CIHI) but collating the data across delivery jurisdictions has proven challenging. As a result, information related to the activity of physician anesthesia providers is routinely excluded from annual physician workforce reports. Our goal was to develop a novel approach to identifying and characterizing the anesthesia workforce on a pan-Canadian scale.

METHODS

The study was approved by the University of Ottawa Office of Research Ethics and Integrity. We developed a methodology to identify physicians who provided anesthesia services in Canada between 1996 and 2018 using data elements from the CIHI National Physician Database. We iteratively consulted with expert advisors and compared the results with Scott's Medical Database, the Canadian Medical Association (CMA) Masterfile, and the College of Family Physicians of Canada membership database.

RESULTS

The methodology identified providers of anesthesia services using data elements from the CIHI National Physician Database, including categories of the National Grouping System, specialty designations, activity levels and participation thresholds. Physicians who provided anesthesia services only sporadically and medical residents-in-training were excluded. This methodology produced estimates of anesthesia providers that aligned with other sources. The process we followed was sequential, transparent, and intuitive, and was strengthened by collaboration and iterative consultation with experts and stakeholders.

CONCLUSIONS

Using physician activity patterns, this novel methodology allows stakeholders to identify which physician provide anesthesia services in Canada. It is an essential step in developing a pan-Canadian anesthesia workforce strategy that can be used to examine patterns and trends related to the workforce and support evidence-informed workforce decision-making. It also establishes a foundation for assessing the effectiveness of a variety of interventions aimed at optimizing physician anesthesia services in Canada.

Surgical Task-Sharing in the Western Canadian Arctic: A Networked Model Between Family Physicians with Enhanced Surgical Skills and Specialist Surgeons

Background

With the loss of generalism in the surgical specialties, there has been a move in Canada to train family physicians in enhanced surgical skills (FP-ESS) to address the surgical needs of rural and remote populations. This research project sought to describe one network integrating FP-ESS and specialist surgeons, focusing on the role of FP-ESS and their relationship with specialist surgeons, in the surgical care of the Beaufort Delta Region of the Northwest Territories of Canada.

Methods

Using a participatory approach, semi-structured interviews were conducted with 22 stakeholders within the surgical system. Interviews were transcribed and reviewed, then imported into NVivo 12 for analysis. First-level coding was performed based on both deductive and inductive reasoning in an iterative fashion during interview collection to develop and refine the codebook. This was followed by second-level categorizing.

Results

The FP-ESS physicians provide cesarean section services to maintain a local obstetrics program, to provide gastrointestinal endoscopy, and to provide emergency on-call support, as described by one stakeholder. FP-ESS work together with specialist surgeons through an informal network keeping surgical care as close to home as possible. FP-ESS within this health regions were seen as “a really big gain to the system.”

Conclusions

This study deepens our understanding of rural surgical service delivery, in particular where FP-ESS and specialist surgeons function collaboratively. It also contributes to strengthening rural surgical systems in Canada and therefore to addressing the health gap between rural/remote/indigenous and urban populations.

Factors affecting job choice among physician anesthesia providers in Uganda: a survey of income composition, discrete choice experiment, and implications for the decision to work rurally

BACKGROUND

One of the biggest barriers to accessing safe surgical and anesthetic care is lack of trained providers. Uganda has one of the largest deficits in anesthesia providers in the world, and though they are increasing in number, they remain concentrated in the capital city. Salary is an oft-cited barrier to rural job choice, yet the size and sources of anesthesia provider incomes are unclear, and so the potential income loss from taking a rural job is unknown. Additionally, while salary augmentation is a common policy proposal to increase rural job uptake, the relative importance of non-monetary job factors in job choice is also unknown.

METHODS

A survey on income sources and magnitude, and a Discrete Choice Experiment examining the relative importance of monetary and non-monetary factors in job choice, was administered to 37 and 47 physician anesthesiologists in Uganda, between May-June 2019.

RESULTS

No providers worked only at government jobs. Providers earned most of their total income from a non-government job (50% of income, 23% of working hours), but worked more hours at their government job (36% of income, and 44% of working hours). Providers felt the most important job attributes were the quality of the facility and scope of practice they could provide, and the presence of a colleague (33% and 32% overall relative importance). These were more important than salary and living conditions (14% and 12% importance).

CONCLUSIONS

No providers accepted the salary from a government job alone, which was always augmented by other work. However, few providers worked only nongovernment jobs. Non-monetary incentives are powerful influencers of job preference, and may be leveraged as policy options to attract providers. Salary continues to be an important driver of job choice, and jobs with fewer income generating opportunities (e.g. private work in rural areas) are likely to need salary augmentation to attract providers.

Qualities of Effective Vital Anaesthesia Simulation Training Facilitators Delivering Simulation-Based Education in Resource-Limited Settings

BACKGROUND

Lack of access to safe and affordable anesthesia and surgical care is a major contributor to avoidable death and disability across the globe. Effective education initiatives are a viable mechanism to address critical skill and process gaps in perioperative teams. Vital Anaesthesia Simulation Training (VAST) aims to overcome barriers limiting widespread application of simulation-based education (SBE) in resource-limited environments, providing immersive, low-cost, multidisciplinary SBE and simulation facilitator training. There is a dearth of knowledge regarding the factors supporting effective simulation facilitation in resource-limited environments. Frameworks evaluating simulation facilitation in high-income countries (HICs) are unlikely to fully assess the range of skills required by simulation facilitators working in resource-limited environments. This study explores the qualities of effective VAST facilitators; knowledge gained will inform the design of a framework for assessing simulation facilitators working in resource-limited contexts and promote more effective simulation faculty development.

METHODS

This qualitative study used in-depth interviews to explore VAST facilitators' perspectives on attributes and practices of effective simulation in resource-limited settings. Twenty VAST facilitators were purposively sampled and consented to be interviewed. They represented 6 low- and middle-income countries (LMICs) and 3 HICs. Interviews were conducted using a semistructured interview guide. Data analysis involved open coding to inductively identify themes using labels taken from the words of study participants and those from the relevant literature.

RESULTS

Emergent themes centered on 4 categories: Persona, Principles, Performance and Progression. Effective VAST facilitators embody a set of traits, style, and personal attributes (Persona) and adhere to certain Principles to optimize the simulation environment, maximize learning, and enable effective VAST Course delivery. Performance describes specific practices that well-trained facilitators demonstrate while delivering VAST courses. Finally, to advance toward competency, facilitators must seek opportunities for skill Progression.Interwoven across categories was the finding that effective VAST facilitators must be cognizant of how context, culture, and language may impact delivery of SBE. The complexity of VAST Course delivery requires that facilitators have a sensitive approach and be flexible, adaptable, and open-minded. To progress toward competency, facilitators must be open to self-reflection, be mentored, and have opportunities for practice.

CONCLUSIONS

The results from this study will help to develop a simulation facilitator evaluation tool that incorporates cultural sensitivity, flexibility, and a participant-focused educational model, with broad relevance across varied resource-limited environments.

Anesthesiology: Resetting Our Sights on Long-term Outcomes: The 2020 John W. Severinghaus Lecture on Translational Science

Anesthesiologists have worked relentlessly to improve intraoperative anesthesia care. They are now well positioned to expand their horizons and address many of the longer-term adverse consequences of anesthesia and surgery. Perioperative neurocognitive disorders, chronic postoperative pain, and opioid misuse are not inevitable adverse outcomes; rather, they are preventable and treatable conditions that deserve attention. The author's research team has investigated why patients experience new cognitive deficits after anesthesia and surgery. Their animal studies have shown that anesthetic drugs trigger overactivity of "memory-blocking receptors" that persists after the drugs are eliminated, and they have discovered new strategies to preserve brain function by repurposing available drugs and developing novel therapeutics that inhibit these receptors. Clinical trials are in progress to examine the cognitive outcomes of such strategies. This work is just one example of how anesthesiologists are advancing science with the goal of improving the lives of patients.

Delivering Essential Surgical Care for Lower-limb Musculoskeletal disorders in the Low-Resource Setting

Background

Mismatched surgeon-anesthesiologist ratios often exist in low-resource settings making safe emergency essential surgical care challenging. This study is an audit of emergency essential procedures performed for lower-limb (LL) musculoskeletal disorders (MSD) when an anesthesiologist was unavailable. It aims to identify strategies for safe anesthesia.

Methods

A 5-year retrospective audit of emergency essential LL orthopedic procedures performed at remote mission hospital in Central India was performed. Out of necessity, a regional anesthesia (RA) protocol was developed in collaboration with anesthesiologists familiar with the setting. The incidence of intraoperative surgical and perioperative anesthesia complications when RA was administered by a surgeon was evaluated.

Results

During this period, 766 emergency essential LL MSDs procedures were performed. An anesthesiologist was available for only 6/766. RA was administered by a surgeon for 283/766. This included spinal anesthesia (SA) for 267/283 patients, peripheral nerve blocks for 16/283. Local infiltration and/or sedation was administered to 477/766. There were 17 intraoperative surgical complications. Anesthesia-related complications included 37/267 patients who required multiple attempts to localize subarachnoid space and SA failure in 9/267 patients all of whom had successful re-administration. Additional sedation and infiltration of local anesthetic was required in 5/267 patients.

Conclusion

Remote pre-anesthesia consultation for high-risk patients, local surgeon-anesthesiologist networking, protocol-guided management, and dedicated short duration of training in anesthesia may be considered as an alternative for delivering RA for emergency essential surgery for LL MSDs due to unavailability of anesthesiologists.

Maternity Units in Rural Hospitals in North Carolina: Successful Models for Staffing and Structure

OBJECTIVES

Almost 15% of all US births occur in rural hospitals, yet rural hospitals are closing at an alarming rate because of shortages of delivering clinicians, nurses, and anesthesia support. We describe maternity staffing patterns in successful rural hospitals across North Carolina.

METHODS

All of the hospitals in the state with ≤200 beds and active maternity units were surveyed. Hospitals were categorized into three sizes: critical access hospitals (CAHs) had ≤25 acute staffed hospital beds, small rural hospitals had ≤100 beds without being defined as CAHs, and intermediate rural hospitals had 101 to 200 beds. Qualitative data were collected at a selection of study hospitals during site visits. Eighteen hospitals were surveyed. Site visits were completed at 8 of the surveyed hospitals.

RESULTS

Nurses in CAHs were more likely to float to other units when Labor and Delivery did not have patients and nursing management was more likely to assist on Labor and Delivery when patient census was high. Anesthesia staffing patterns varied but certified nurse anesthetists were highly used. CAHs were almost twice as likely to accept patients choosing a trial of labor after cesarean section (CS) than larger hospitals, but CS rates were similar across all hospital types. Hospitals with only obstetricians as delivering providers had the highest CS rate (32%). The types of hospitals with the lowest CS rates were the hospitals with only family physicians (24%) or high proportions of certified nurse midwives (22%).

CONCLUSIONS

Innovative staffing models, including family physicians, nurse midwives, and nurse anesthetists, are critical for the survival of rural hospitals that provide vital maternity services in underserved areas.

Mobile medical simulation for rural anesthesia providers: A feasibility study

INTRODUCTION

Family practice anesthesia (FPA) providers are family physicians trained to deliver anesthesia care; they often practice in rural hospitals to facilitate surgical care. FPA providers in rural hospitals face challenges including professional isolation and limited opportunities for formal continuing education. To address needs identified by FPA providers, we piloted mobile medical simulation in rural Saskatchewan.

METHODS

Using a logic model framework, we evaluated feasibility of a one-day interdisciplinary mobile simulation workshop for healthcare providers in a rural Saskatchewan hospital. As part of this mixed methods pilot study, we interviewed stakeholders to explore their perceptions of human and financial resources associated with delivering medical simulations in rural locations. Multiple simulation scenarios were utilized to train participants in clinical and professional skills. Participants completed pre- and post-workshop surveys to evaluate their experience.

RESULTS

Financial and human resources included cost of renting, transportation of mannequins, and the time required to create the scenarios. Participants (n = 10) reported improved knowledge and found the experience valuable. The session prompted participants to reflect on their deficiencies in certain clinical procedures/skills and highlight learning strategies to address the gap.

DISCUSSION

Mobile medical simulation brought continuing medical education (CME) to health professionals in a rural location, but the program was expensive. Our logic model may inform educators and administrators considering mobile medical simulation for physicians in rural areas when balancing resource allocation and the organization's commitment to CME for rural physicians.

Influence of the definition of rurality on geographic differences in HIV outcomes in British Columbia: a retrospective cohort analysis

BACKGROUND

Improving rural health is often identified as a priority area for research and policy in Canada. We examined how findings on HIV outcomes (virologic suppression) can vary depending on the definition of rurality used.

METHODS

We performed retrospective cohort analyses using the Comparative Outcomes and Service Utilization Trends study population-based cohort of adults (age ≥ 19 yr) living with HIV in British Columbia between Apr. 1, 2012, and Mar. 31, 2013. We performed univariate logistic regression analyses using the following geographic variables to predict HIV virologic suppression: rurality defined by forward sortation area, by Statistical Area Classification and by health authority. We mapped suppression using geographic information systems.

RESULTS

Virologic suppression was observed in 5605 (65.2%) of 8598 participants. In univariate analysis, rurality defined by Statistical Area Classification (odds ratio [OR] 0.73, 95% confidence interval [CI] 0.65-0.82), but not by forward sortation area, was associated with lower odds of suppression. When we examined suppression by health authority, Northern Health had the lowest odds of suppression (OR 0.46, 95% CI 0.36-0.58 compared to Vancouver Coastal Health). Geographic information systems mapping showed poorer suppression in northern areas.

INTERPRETATION

Health outcome findings can vary depending on the definition of the geographic variable. When including geographic variables, researchers should carefully consider variable definitions and whether other classification systems, such as north-south, are more appropriate than rurality for their analysis.

Musings from an Unlikely Clinician-Scientist: 2018 American Society of Anesthesiologists Excellence in Research Award

This article, which stems from the 2018 American Society of Anesthesiologists Excellence in Research Award Lecture, aims to encourage young investigators, offer advice, and share several early life experiences that have influenced the author's career as an anesthesiologist and clinician-scientist. The article also describes key discoveries that have increased understanding of the role of γ-aminobutyric acid type A (GABAA) receptors in health and disease. The author's research team identified the unique pharmacologic properties of extrasynaptic GABAA receptors and their role in the anesthetic state. The author's team also showed that extrasynaptic GABAA receptors expressed in neuronal and nonneuronal cells contribute to a variety of disorders and are novel drug targets. The author's overarching message is that young investigators must create their own unique narratives, train hard, be relentless in their studies and-most important-enjoy the journey of discovering new truths that will ultimately benefit patients.
