A Prospective Observational Study of Anesthesia-Related Adverse Events and Postoperative Complications Occurring During a Surgical Mission in Madagascar

The delivery and challenges of Pediatric Anesthesia within the humanitarian sector: Médecins Sans Frontières and Mercy Ships

Access to healthcare is inequitable. Poverty, natural disasters and war disproportionally effect those most vulnerable, including children. Non-governmental organizations (NGO) hold a vital role in providing pediatric care in these contexts. Here we describe the delivery and challenges of Pediatric Anesthesia with two such non-governmental organizations; Médecins Sans Frontières (MSF) and Mercy Ships. Descriptions of both are followed by case studies.

Outcomes of Short-Term Surgical Trips in Otolaryngology-Head and Neck Surgery: A Scoping Review

OBJECTIVE

This scoping review aims to explore the current body of literature to characterize how short-term surgical trips (STSTs) in Otolaryngology-Head and Neck Surgery (OtoHNS) contribute to surgical, educational, and sustainability-based outcomes in low- and middle-income countries (LMICs). We aim to use these data to synthesize aspects of STSTs that are successful with the hopes of shaping future global efforts.

DATA SOURCES

Data sources included Ovid MEDLINE, Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus.

REVIEW METHODS

A comprehensive search was conducted on several databases from inception to October 14, 2021. We included primary studies exploring any surgical or educational outcomes of global short-term surgical endeavors within LMICs. Data were then extracted to evaluate the heterogenous body of literature that exists, characterizing the surgical, educational, and sustainability-based outcomes.

RESULTS

Forty-Seven studies were included in the final analysis. Most publications were focused on surgical interventions (39 of 47; 82.9%); 13 (27.7%) studies included education as the primary aim and 12 (25.5%) considered sustainability a significant aim. Of the 94 first and last authors, there were zero first authors and only one last author with an LMIC affiliation. Twenty-six studies (55%) mentioned that any patients were seen in follow-up, ranging from one day to five years.

CONCLUSION

Our scoping review demonstrates that most STSTs have focused primarily on surgical procedures with a lack of appropriate long-term follow-up. However, the available outcome-based information presented helps identify factors that characterize a strong short-term global surgical program.

Endoplasmic reticulum stress in airway hyperresponsiveness

Airway hyperresponsiveness(AHR) is a major clinical phenomenon in lung diseases (asthma, COPD and pulmonary fibrosis) and not only a high-risk factor for perioperative airway spasm leading to hypoxaemia, haemodynamic instability and even "silent lung", but also a potential risk for increased mortality from underlying diseases (e.g. asthma, COPD). Airway reactivity is closely linked to airway inflammation, remodelling and increased mucus secretion, and endoplasmic reticulum stress is an important mechanism for the development of these pathologies. This review, therefore, focuses on the effects of endoplasmic reticulum stress on the immune cells involved in airway hyperreactivity (epithelial cells, dendritic cells, eosinophils and neutrophils) in inflammation and mucus & sputum secretion; and on the differentiation and remodelling of airway smooth muscle cells and epithelial cells. The aim is to clarify the mechanisms associated with endoplasmic reticulum stress in airway hyperresponsiveness and to find new ideas and methods for the prevention of airway hyperresponsiveness in the perioperative period.

2020 guidelines for conducting plastic reconstructive short-term surgical projects in low-middle income countries

Many low- or middle-income countries (LMICs) continue to suffer from a lack of safe and timely essential and emergency surgery despite growing attention to this problem. Short-term surgical projects (STSPs) continue to play an important role in addressing LMIC unmet surgical need and strengthening local healthcare systems. Guidelines here present recommendations for performing plastic reconstructive STSPs for pediatric patients in a safe, ethical, and effective manner. These guidelines represent consensus physician expert opinions, assembled collaboratively by members of Volunteers in Plastic Surgery and the Society for Pediatric Anesthesia's global health committee, with broad input from physicians practicing daily in LMICs. Organizations must partner with hosts to thoughtfully plan and carefully execute STSPs. We outline crucial items to STSP success, including choice of host facility, team selection, patient selection, staffing, ensuring proper equipment and supplies, disinfecting reusable equipment, creation of a safety culture, and data collection for quality assessment/improvement and research. Patient factors are discussed and recommendations given for developing exclusion criteria, as well as for determining which patients and procedures may require the team to include expertise in pediatric anesthesia or critical care. We recommend that educational opportunities for hosts are sought and advanced to optimize education/training at both the resident and post-trainee levels. Host education during STSPs has become crucial as LMICs ramp up training at a time when their surgical volumes remain grossly behind well-resourced countries. Recommendations here aim to assist organizations, hosts, and volunteers as they navigate the enormously complex and ever changing STSP environment. Patient safety and transfer of knowledge and skills should be central concerns of all who participate in this highly rewarding endeavor.

Short-term surgical trips: local collaboration and its effects on complications and patient satisfaction

PURPOSE

Short-term surgical missions can provide communities in need with desired expertise; however, it is uncertain who will manage the complications after visiting experts leave. Poor outcomes, decreased patient satisfaction, and tension on the healthcare system develop when local providers, often excluded from the initial patient care, are unable to cope with subsequent morbidity.

METHODS

Two-year retrospective review of pediatric general, plastic, and reconstructive surgery, and urology cases performed by a relief organization in the developing world. Case complexity and postoperative complications were analyzed. Phone interviews conducted with patients/families to quantify postoperative outcomes and satisfaction.

RESULTS

474 surgeries were performed on pediatric patients with 60% response rate. Respondents stratified into three levels of complexity: 159 simple, 72 intermediate, and 54 advanced surgeries. Six (2.1%) high-level complications occurred. No association between the complexity of the surgery and the occurrence of a complications. 83.5% were satisfied with outcomes and > 92% were happy with the provided support.

CONCLUSION

Facilitating visiting and local surgeons performing cases together increases the expertise of local providers, strengthens infrastructure, and establishes clear follow-up. Despite complications, patients and families continued to recommend care to family and friends by the relief organization and were happy with support from local providers. Engaging local providers is the gold-standard for short-term trips.

A prospective observational study of postoperative follow-ups and outcomes at a nonprofit, internationally supported pediatric surgery center in Guatemala

BACKGROUND

Global surgical access is unequally distributed, with the greatest surgical burden in low- and middle-income countries, where surgical care is often supplemented by nongovernmental organizations. Quality data from organizations providing this care are rarely collected or reported. The Moore Pediatric Surgery Center in Guatemala City, Guatemala, is unique in that it offers a permanently staffed, freestanding pediatric surgical center. Visiting surgical teams supplement the local permanent staff by providing a broad range of pediatric subspecialty surgical and anesthesia care.

AIM

The aim of this study was to collect and report the incidence of completed postoperative follow-up visits and outcome measures at this nonprofit, internationally supported surgery center.

METHODS

De-identified demographic and postoperative outcome data were collected from each routinely scheduled, one-week pediatric surgical mission trip and incorporated into an electronic data collection system. Emphasis was placed on identification of completed postoperative visits and associated perioperative complications. After 27 months of data collection, results were analyzed to identify and quantify trends in patient follow-ups and postoperative outcomes.

RESULTS

Over 27 months, 1639 pediatric surgical procedures were performed and included in data analysis. The percentage of completed postoperative day-1 follow-up visits was 99.1%, and seven complications were identified out of these 1624 cases (postoperative complication rate of 0.4%). The percentage of completed first postoperative visits after discharge was 93.3%, and 67 complications were identified out of these 1530 cases (postoperative complication rate of 4.4%).

CONCLUSION

Our data show a high rate of postoperative follow-up visits completed and low perioperative complication rates similar to those of high-income countries. Our data suggest that The Moore Surgery Center model of care offers an alternative to the short-term visiting surgical model by incorporating the local system and allows for improved follow-up, outcomes analysis, and high quality of care.

The challenge of safe anesthesia in developing countries: defining the problems in a medical center in Cambodia

Background

The International Standards for a Safe Practice of Anesthesia (ISSPA) were developed on behalf of the World Federation of Societies of Anaesthesiologists and the World Health Organization. It has been recommend as an assessment tool that allows anesthetic providers in developing countries to assess their compliance and needs. This study was performed to describe the anesthesia service in one main public hospital during an 8-month medical mission in Cambodia and evaluate its anesthetic safety issues according to the ISSPA.

Methods

We conduct a retrospective study involving 1953 patients at the Preah Ket Mealea hospital. Patient demographics, anesthetic techniques, and complications were reviewed according to the registers of the anesthetic services and questionnaires. The inadequacies in personnel, facilities, equipment, medications, and conduct of anesthesia drugs were recorded using a checklist based on the ISSPA.

Results

A total of 1792 patients received general and regional anesthesia in the operating room, while 161 patients receiving sedation for gastroscopy. The patients’ mean age was 45.0 ± 16.6 years (range, 17–87 years). The three most common surgical procedures were abdominal (52.0%; confidence interval [CI], 49.3–54.7), orthopedic (27.6%; CI, 25.2–29.9), and urological surgery (14.7%; CI, 12.8–16.6). General anesthesia, spinal anesthesia, and brachial plexus block were performed in 54.3% (CI, 51.7–56.8), 28.2% (CI, 25.9–30.5), and 9.4% (CI, 7.9–10.9) of patients, respectively. One death occurred. Twenty-six items related to professional aspects, monitoring, and conduct of anesthesia did not meet the ISSPA-recommended standards. A lack of commonly used drugs and monitoring equipment was noted, posing major threats to the safety of anesthesia practice, especially in emergency situations.

Conclusions

This study adds to the scarce literature on anesthesia practice in low- and middle-income countries such as Cambodia. Future medical assistance should help to strengthen these countries’ inadequacies, allowing for the adoption of international standards for the safe practice of anesthesia.

Anaesthesia care providers employed in humanitarian settings by Médecins Sans Frontières: a retrospective observational study of 173 084 surgical cases over 10 years

OBJECTIVE

To describe the extent to which different categories of anaesthesia provider are used in humanitarian surgical projects and to explore the volume and nature of their surgical workload.

DESIGN

Descriptive analysis using 10 years (2008-2017) of routine case-level data linked with routine programme-level data from surgical projects run exclusively by Médecins Sans Frontières-Operational Centre Brussels (MSF-OCB).

SETTING

Projects were in contexts of natural disaster (ND, entire expatriate team deployed by MSF-OCB), active conflict (AC) and stable healthcare gaps (HG). In AC and HG settings, MSF-OCB support pre-existing local facilities. Hospital facilities ranged from basic health centres with surgical capabilities to tertiary referral centres.

PARTICIPANTS

The full dataset included 178 814 surgical cases. These were categorised by most senior anaesthetic provider for the project, according to qualification: specialist physician anaesthesiologists, qualified nurse anaesthetists and uncertified anaesthesia providers.

PRIMARY OUTCOME MEASURE

Volume and nature of surgical workload of different anaesthesia providers.

RESULTS

Full routine data were available for 173 084 cases (96.8%): 2518 in ND, 42 225 in AC, 126 936 in HG. Anaesthesia was predominantly led by physician anaesthesiologists (100% in ND, 66% in AC and HG), then nurse anaesthetists (19% in AC and HG) or uncertified anaesthesia providers (15% in AC and HG). Across all settings and provider groups, patients were mostly healthy young adults (median age range 24-27 years), with predominantly females in HG contexts, and males in AC contexts. Overall intra-operative mortality was 0.2%.

CONCLUSION

Our findings contribute to existing knowledge of the nature of anaesthetic provision in humanitarian settings, while demonstrating the value of high-quality, routine data collection at scale in this sector. Further evaluation of perioperative outcomes associated with different models of humanitarian anaesthetic provision is required.

Reducing Surgical Site Infections During Otolaryngology Surgical Missions

OBJECTIVES

To determine what measures an otolaryngology-head and neck surgery team might adopt to decrease the incidence of surgical site infection (SSI) on a short-term surgical mission. Despite concerns about safety and efficacy, short-term surgical missions remain the predominant structure for humanitarian surgical care in low- and middle-income countries (LMIC). Hospitals in high-income countries strive to improve surgical outcomes through implementation of World Health Organization (WHO) safe surgery guidelines. Reduction of SSI risk is a key part of this effort.

METHODS

Literature review and practical experience.

RESULTS

WHO recommendations for reducing SSI are based largely on research done in the North America and Europe. LMIC populations are younger; comorbidities are fewer; infectious disease and trauma are prevalent; and delays in access to care are common. SSI are much more frequent in resource-limited settings. Recommendations regarding preoperative assessment, operating room environment, instrument sterilization, surgical antibiotic prophylaxis, surgical site preparation, gloving, draping, and postsurgical care are reviewed in the context of a surgical mission at a typical LMIC government hospital.

CONCLUSION

Many of the WHO guidelines on reduction of SSI are logical and applicable to the short-term surgical missions; others may need to be modified. Careful prospective data collection and clinical trials are needed to learn which interventions are valid and which should be changed.
