ABSTRACT

BACKGROUND: Plastic and reconstructive surgical teams visiting from Australia, a high-income country, have delivered cleft surgical services to Timor Leste since 2000 on a volunteer basis. This paper aims to estimate the economic benefit of correcting cleft deformities in this new nation as it evolved its healthcare delivery service from independence in 1999. METHODS: We have utilised a prospective database of all cleft surgical interventions performed during 44 plastic surgical missions over the last 18 years. The disability-adjusted life year (DALY) framework was used to calculate the total DALYs averted by primary cleft lip and palate repair. The 2004 global burden of disease disability weights were used. Economic benefits were calculated using the gross national income (GNI) and the value of a statistical life (VSL) methods for Timor Leste. Estimates were adjusted for treatment effectiveness, counterfactual cases, and complications. Cost estimates included the local hospitalisation costs, the foregone salaries of the visiting surgeons and nurses, other costs associated with providing surgical care, and an estimate for foregone wages of the patients or their carers. Sensitivity analysis was performed with income elasticity set to 0.55, 1.0, and 1.5. RESULTS: During 44 visiting plastic surgical missions to Timor Leste, 1500 procedures were performed, including 843 primary cleft lip and palate operations. The cleft procedures resulted in the aversion of 842 DALYs and an economic return to Timor Leste of USD 2.2 million (GNI-based) or USD 197,917 (VSL-based). Our programme cost USD 705 per DALY averted. The economic return on investment was 0.3:1 (VSL-based) or 3.8:1 (GNI-based). CONCLUSION: A sustained and consistent visiting team approach providing repair of cleft lip and palate defects has resulted in considerable economic gain for Timor Leste over an 18-year period. The training of a local surgeon and multidisciplinary team with ongoing support to the in-country cleft service is expected to reduce the cost per DALY averted once the surgeon and team are able to manage clefts independently.

ABSTRACT

BACKGROUND: The Australian and New Zealand Audit of Surgical Mortality (ANZASM) National Report 2015 found that within the cohort of audited deaths, 85% were emergencies with acute life-threatening conditions, and by far, the most common procedures were laparotomy and colorectal procedures. Emergency laparotomy outcomes have shown improvement through audit and reporting in the UK. The purpose of this study was to determine the outcome of emergency laparotomy in the state of Victoria, Australia. METHOD: The Dr Foster Quality Investigator (DFQI) database was interrogated for a set of Australian Classification of Health Intervention (ACHI) codes defined by the authors as representing an emergency laparotomy. The dataset included patients who underwent emergency laparotomy from July 2007 to July 2016 in all Victorian hospitals. RESULTS: There were 23,115 emergency laparotomies conducted over 9 years in 66 hospitals. Inpatient mortality was 2036/23,115 (8.8%). Mortality in the adult population increased with age and reached 18.1% in those patients that were 80 years or older. 51.3% were females, and there was no significant difference in survival between genders. Patients with no recorded comorbidities had a mortality of 4.3%, whereas those with > 5 comorbidities had 19.3% mortality. CONCLUSION: Administrative data accessed via a tool such as DFQI can provide useful population data to guide further evidence-based improvement strategies. The mortality for emergency laparotomy within Victorian hospitals is comparable, if not better than that seen in overseas studies. There is a need to continue routine audit of mortality rates and implement systems improvement where necessary.

ABSTRACT

Progress in achieving "universal access to safe, affordable surgery, and anesthesia care when needed" is dependent on consensus not only about the key messages but also on what metrics should be used to set goals and measure progress. The Lancet Commission on Global Surgery not only achieved consensus on key messages but also recommended 6 key metrics to inform national surgical plans and monitor scale-up toward 2030. These metrics measure access to surgery, as well as its timeliness, safety, and affordability: (1) Two-hour access to the 3 Bellwether procedures (cesarean delivery, emergency laparotomy, and management of an open fracture); (2) Surgeon, Anesthetist, and Obstetrician workforce >20/100,000; (3) Surgical volume of 5000 procedures/100,000; (4) Reporting of perioperative mortality rate; and (5 and 6) Risk rates of catastrophic expenditure and impoverishment when requiring surgery. This article discusses the definition, validity, feasibility, relevance, and progress with each of these metrics. The authors share their experience of introducing the metrics in the Pacific and sub-Saharan Africa. We identify appropriate messages for each potential stakeholder-the patients, practitioners, providers (health services and hospitals), public (community), politicians, policymakers, and payers. We discuss progress toward the metrics being included in core indicator lists by the World Health Organization and the World Bank and how they have been, or may be, used to inform National Surgical Plans in low- and middle-income countries to scale-up the delivery of safe, affordable, and timely surgical and anesthesia care to all who need it.

ABSTRACT

BACKGROUND: Timely access to emergency and essential surgical care (EESC) and anaesthesia in low- and middle-income countries (LMICs) prevents premature death, minimises lifelong disability and reduces their economic impact on families and communities. Papua New Guinea is one of the poorest countries in the Pacific region, and provides much of its surgical care at a district hospital level. We aimed to evaluate the surgical capacity of a district hospital in PNG and estimate the effectiveness of surgical interventions provided. METHODS: We performed a prospective study to calculate the number of DALYs averted for 465 patients treated with surgical care over a 3-month period (Sep-Nov 2013) in Alotau Hospital, Milne Bay Province, PNG (pop 210,000). Data were also collected on infrastructure, workforce, interventions provided and equipment available using the World Health Organization's Integrated Management of Emergency and Essential Surgical Care Toolkit, a survey to assess EESC and surgical capacity. We also performed a retrospective one-year audit of surgical, obstetric and anaesthetic care to provide context with regards to annual disease burden treated and surgical activity. RESULTS: EESC was provided by 11 Surgeons/Anaesthetists/Obstetricians (SAO) providers, equating to 5.7 per 100,000 population (including 4 nurse anaesthetists). They performed 783/100,000 procedures annually. Over the 3-month prospective study period, 4954 DALYs were averted by 465 surgical interventions, 52 % of which were elective. This equates to 18,330 DALYs averted annually or, approximately 18 % of the published but estimated disease burden in the Province in the 2013 Global Burden of Disease Study. The overall peri-operative mortality rate was 1.29 %, with 0.41 % for elective procedures and 2.25 % for emergencies. CONCLUSIONS: Much of the burden of surgical disease in Papua New Guinea presenting to Alotau General Hospital serving Milne Bay Province can be effectively treated by a small team providing emergency and essential surgical care. This is despite a relatively low surgical volume and limited numbers of trained surgical anaesthesia obstetric providers, and likely underservicing. The ability of surgical care to avert disease in Papua New Guinea highlights its importance to public health in LMICs.

ABSTRACT

BACKGROUND: Surgical techniques and pre-operative patient evaluation have improved since the initial development of the Barcelona clinic liver cancer staging system. The optimal treatment for solitary hepatocellular carcinoma ≥5 cm remains unclear. The aim of this study was to review the long-term survival outcomes of hepatic resection versus transarterial chemoembolisation (TACE) for solitary large tumours. METHODS: EMBASE, MEDLINE, Pubmed and the Cochrane database were searched for studies comparing resection with TACE for solitary HCC ≥5 cm. The primary outcome was overall survival at 1, 3 and 5 years. RESULTS: The meta-analysis combined the results of four cohort studies including 861 patients where 452 underwent hepatic resection and 409 were treated with TACE to an absence of viable tumour. The pooled HR for 3 year OS rate calculated using the random effects model was 0.60 (95% CI 0.46-0.79, p < 0.001; I2 = 54%, P = 0.087). The pooled HR for 5 year OS rate calculated using the random effects model was 0.59 (95% CI 0.43-0.81, p = 0.001; I2 = 80%, P = 0.002). CONCLUSION: Hepatic resection has been shown to result in greater survivability and time to disease progression than TACE for solitary HCC ≥5 cm. Where a patient is fit for surgery, has adequate liver function and a favourable tumour, resection should be considered.

ABSTRACT

BACKGROUND: Case volume per 100 000 population and perioperative mortality rate (POMR) are key indicators to monitor and strengthen surgical services. However, comparisons of POMR have been restricted by absence of standardised approaches to when it is measured, the ideal denominator, need for risk adjustment, and whether data are available. We aimed to address these issues and recommend a minimum dataset by analysing four large mixed surgical datasets, two from well-resourced settings with sophisticated electronic patient information systems and two from resource-limited settings where clinicians maintain locally developed databases. METHODS: We obtained data from the New Zealand (NZ) National Minimum Dataset, the Geelong Hospital patient management system in Australia, and purpose-built surgical databases in Pietermaritzburg, South Africa (PMZ) and Port Moresby, Papua New Guinea (PNG). Information was sought on inclusion and exclusion criteria, coding criteria, and completeness of patient identifiers, admission, procedure, discharge and death dates, operation details, urgency of admission, and American Society of Anesthesiologists (ASA) score. Date-related errors were defined as missing dates and impossible discrepancies. For every site, we then calculated the POMR, the effect of admission episodes or procedures as denominator, and the difference between in-hospital POMR and 30-day POMR. To determine the need for risk adjustment, we used univariate and multivariate logistic regression to assess the effect on relative POMR for each site of age, admission urgency, ASA score, and procedure type. FINDINGS: 1 365 773 patient admissions involving 1 514 242 procedures were included, among which 8655 deaths were recorded within 30 days. Database inclusion and exclusion criteria differed substantially. NZ and Geelong records had less than 0·1% date-related errors and greater than 99·9% completeness. PMZ databases had 99·9% or greater completeness of all data except date-related items (94·0%). PNG had 99·9% or greater completeness for date of birth or age and admission date and operative procedure, but 80-83% completeness of patient identifiers and date related items. Coding of procedures was not standardised, and only NZ recorded ASA status and complete post-discharge mortality. In-hospital POMR range was 0·38% in NZ to 3·44% in PMZ, and in NZ it underestimated 30-day POMR by roughly a third. The difference in POMR by procedures instead of admission episodes as denominator ranged from 10% to 70%. Age older than 65 years and emergency admission had large independent effects on POMR, but relatively little effect in multivariate analysis on the relative odds of in-hospital death at each site. INTERPRETATION: Hospitals can collect and provide data for case volume and POMR without sophisticated electronic information systems. POMR should initially be defined by in-hospital mortality because post-discharge deaths are not usually recorded, and with procedures as denominator because details allowing linkage of several operations within one patient's admission are not always present. Although age and admission urgency are independently associated with POMR, and ASA and case mix were not included, risk adjustment might not be essential because the relative odds between sites persisted. Standardisation of inclusion criteria and definitions is needed, as is attention to accuracy and completeness of dates of procedures, discharge and death. A one-page, paper-based form, or alternatively a simple electronic data collection form, containing a minimum dataset commenced in the operating theatre could facilitate this process. FUNDING: None.

ABSTRACT

BACKGROUND: The purpose of this study is to ascertain whether acute burn management (ABM) is available at health facilities in low- and middle-income countries (LMICs). METHOD: The study used the World Health Organization situational analysis tool (SAT) which is designed to assess emergency and essential surgical care and includes data points relevant to the acute management of burns. The SAT was available for 1413 health facilities in 59 countries. RESULTS: A majority (1036, 77.5 %) of the health facilities are able to perform ABM. The main reasons for the referral of ABM are lack of skills (53.4 %) and non-functioning equipment (52.2 %). Considering health centres and district/rural/community hospitals that referred due to lack of supplies/drugs and/or non-functioning equipment, almost half of the facilities were not able to provide continuous and consistent access to the equipment required either for resuscitation or to perform burn wound debridement. Out of the facilities that performed ABM, 379 (36.6 %) are capable of carrying out skin grafts and contracture release, which is indicative of their ability to manage full thickness burns. However the magnitude of full thickness burns managed was limited in half of these facilities, as they did not have access to a blood bank. CONCLUSION: The initial management of acute burns is generally available in LMICs, however it is constrained by the inability to perform resuscitation (19 %) and/or burn wound debridement (10 %). For more severe burns, an inability to perform skin grafting or contracture release limits definitive management of full thickness burns, whilst lack of availability to blood further compromises the treatment of major burns.

ABSTRACT

BACKGROUND: Papua New Guinea (PNG) is a developing Pacific Nation of 7.3 million people. Although neurosurgery training was introduced to PNG in the year 2000, it was in 2003 that a neurosurgery service was established. Prior to this time, neurosurgery in PNG was performed by general surgeons, with some assistance from visiting Australian neurosurgeons. Neurosurgical training was introduced to PNG in 2000. The model involved a further 3 years of training for a surgeon who had already completed 4 years of general surgical training. We aim to review the output, outcomes and impact achieved by training the first national neurosurgeon. METHODS: The data on activity (output) and outcomes were collected prospectively from 2003­2012. Ongoing mentoring and continuing professional development were provided through annual neurosurgical visits from Australia. There were serious limitations in the provision of equipment, with a lack of computerized tomographic or MR imaging, and adjuvant oncological services. RESULTS: There were 1618 neurosurgery admissions, 1020 neurosurgical procedures with a 5.74 % overall mortality. Seventy percent of cases presented as emergencies. There were improved outcomes, particularly for head injuries, whilst hydrocephalus was managed with an acceptable morbidity and revision rate. CONCLUSIONS: The training of a neurosurgeon resulted in PNG patients receiving a better range of surgical services, with a lower mortality. The outcomes able to be delivered were limited by late presentations of patients and lack of resources including imaging. These themes are familiar to all low- and middle-income countries (LMICs) and this may serve as a model for other LMIC neurosurgical services to adopt as they consider whether to establish and develop neurosurgical and other sub-specialist surgical services.

ABSTRACT

INTRODUCTION: A decline in surgical deaths has been observed in Australia since the introduction of the Australian and New Zealand Audit of Surgical Mortality (ANZASM). The current study was conducted to determine whether the perioperative mortality rate (POMR) has also declined. METHODS: This study is a retrospective review of the POMR for surgical procedures in Australian public hospitals between July 2009 and June 2013, using data obtained from the Australian Institute of Health and Welfare. Operative procedures contained in the Australian Refined Diagnosis Related Groups were selected and the POMR was modelled using urgency of admission, age and gender as explanatory covariates. RESULTS: The POMR in Australian public hospitals reduced by 15.4 % over the 4-year period. The emergency admissions POMR dropped from 1.40 to 1.12 %, and the elective admissions POMR from 0.09 to 0.08 %. The binary logistic regression model used to predict patient mortality showed emergency admissions to have a higher POMR than elective, being more evident at older ages. For emergency admissions, the difference in POMR between females and males increased with age, from about 55 years onwards, with females being lower. For elective surgeries, the difference between males and females was of little practical importance across ages. CONCLUSIONS: The reduction in the POMR in Australia confirms the reduction in surgical deaths reported to ANZASM. Continuing to monitor POMR will be important to ensure the safest surgery in Australia. Further investigations into case-mix will allow better risk adjustment and comparison between regions and time-periods, to facilitate continuous quality improvement.

ABSTRACT

BACKGROUND: Surgical conditions represent a significant proportion of the global burden of disease, and therefore, surgery is an essential component of health systems. Achieving universal health coverage requires effective monitoring of access to surgery. However, there is no widely accepted standard for the required capabilities of a first-level hospital. We aimed to determine whether a group of operations could be used to describe the delivery of essential surgical care. METHODS: We convened an expert panel to identify procedures that might indicate the presence of resources needed to treat an appropriate range of surgical conditions at first-level hospitals. Using data from the World Health Organization Emergency and Essential Surgical Care Global database, collected using the WHO Situational Analysis Tool (SAT), we analysed whether the ability to perform each of these procedures-which we term "bellwether procedures"-was associated with performing a full range of essential surgical procedures. FINDINGS: The ability to perform caesarean delivery, laparotomy, and treatment of open fracture was closely associated with performing all obstetric, general, basic, emergency, and orthopaedic procedures (p < 0.001) in the population that responded to the WHO SAT Survey. Procedures including cleft lip, cataract, and neonatal surgery did not correlate with performing the bellwether procedures. INTERPRETATION: Caesarean delivery, laparotomy, and treatment of open fractures should be standard procedures performed at first-level hospitals. With further validation in other populations, local managers and health ministries may find this useful as a benchmark for what first-level hospitals can and should be able to perform on a 24/7 basis in order to ensure delivery of emergency and essential surgical care to their population. Those procedures which did not correlate with the bellwether procedures can be referred to a specialized centre or collected for treatment by a visiting specialist team.

ABSTRACT

INTRODUCTION: The unmet global burden of surgical disease is substantial. Currently, two billion people do not have access to emergency and essential surgical care. This results in unnecessary deaths from injury, infection, complications of pregnancy, and abdominal emergencies. Inadequately treated surgical disease results in disability, and many children suffer deformity without corrective surgery. METHODS: A consensus meeting was held between representatives of Surgical and Anaesthetic Colleges and Societies to obtain agreement about which indicators were the most appropriate and credible. The literature and state of national reporting of perioperative mortality rates was reviewed by the authors. RESULTS: There is a need for a credible national and/or regional indicator that is relevant to emergency and essential surgical care. We recommend introducing the perioperative mortality rate (POMR) as an indicator of access to and safety of surgery and anaesthesia. POMR should be measured at two time periods: death on the day of surgery and death before discharge from hospital or within 30 days of the procedure, whichever is sooner. The rate should be expressed as the number of deaths (numerator) over the number of procedures (denominator). The option of before-discharge or 30 days is practical for those low- to middle-income countries where postdischarge follow-up is likely to be incomplete, but it allows those that currently can report 30-day mortality rates to continue to do so. Clinical interpretation of POMR at a hospital or health service level will be facilitated by risk stratification using age, urgency (elective and emergency), procedure/procedure group, and the American Society of Anesthesiologists grade. CONCLUSIONS: POMR should be reported as a health indicator by all countries and regions of the world. POMR reporting is feasible, credible, achieves a consensus of acceptance for reporting at national level. Hospital and Service level POMR requires interpretation using simple measures of risk adjustment such as urgency, age, the condition being treated or the procedure being performed and ASA status.

ABSTRACT

BACKGROUND: In 2009, Barwon Health designed a risk stratification model for mortality in major colorectal surgery with the use of only preoperative risk factors. The Barwon Health 2009 model was shown to predict mortality reliably, and it was comparable to other models, such as the original, POSSUM. However, the Barwon Health 2009 model was never validated with data other than those used to develop the model. OBJECTIVE: The aim of this study was to perform temporal and external validation of the Barwon Health 2009 model and to compare it with other published models. DESIGN: : The temporal validation was a prospective observational study, whereas the external validation was a retrospective observational study. The discrimination and calibration of the models were assessed by using the area under receiver operator characteristic and χ test of Hosmer-Lemeshow goodness-of-fi technique. SETTINGS: This is a multi-institutional study. Data were collected from 2008 to 2010. RESULTS: There were 474 major colorectal cases at Geelong Hospital (temporal validation) and 389 cases at Western Hospital (external validation). The overall mortality rate was 5.10% and 1.03%. In the comparison of the 2 demographics, Geelong Hospital had a higher proportion of patients who were older and had higher ASA scores and comorbidity counts, whereas Western Hospital surgeons were operating on a higher number of urgent cases. Despite the differences, the Barwon Health 2009 model was able to discriminate mortality reliably (area under receiver operator characteristic = 0.753) but had poor model calibration (p < 0.001) on temporal validation. Hence, the model was recalibrated to predict mortality accurately(area under receiver operator characteristic = 0.772; p = 0.83), and this was successfully validated at Western Hospital (area under receiver operator characteristic = 0.788; p = 0.24). CONCLUSIONS: We have developed a model that can accurately predict mortality after major colorectal surgery by using only data that are available preoperatively. After recalibration, the model was successfully validated in a second hospital.

ABSTRACT

BACKGROUND: Surgical smoke or plume is produced by a variety of surgical coagulators and dissectors. A number of jurisdictions have recently introduced policies to reduce the associated occupational health risks including WorkSafe Victoria and New South Wales Health. METHOD: This paper is a narrative review of potential risks, including any associated with COVID-19, and options for mitigation. RESULTS: Surgical smoke or plume contains potentially toxic chemicals, some of which are carcinogens. Plume may also contain live virus, notably Human Papilloma and Hepatitis B, though any possible viral transmission is limited to a few case reports. Despite identifying COVID-19 ribonucleic acid fragments in various body tissues and fluids there are no current reports of COVID-19 transmission. Although plume is rapidly removed from the atmosphere in modern operating rooms, it is still inhaled by the operative team. Mitigation should include ensuring diathermy devices have evacuators while plume extraction should be standard for laparoscopic procedures. Consideration needs to be given to the potential to compromise the operating field of view, or the noise of the extractor impairing communication. There is an increasing range of suitable products on the market. The future includes pendant systems built into the operating room. CONCLUSION: The potential risks associated with surgical plume cannot be ignored. Health services should invest in plume extraction devices with a view to protecting their staff. The conduct of the operation should not be compromised by the devices chosen. Future operating theatres need to be designed to minimize exposure to plume.

ABSTRACT

Clinical quality registries (CQRs) systematically collect data on pre-agreed markers of quality of care for a given procedure, that can be reliably and reproducibly defined and collected across multiple sites. Data is then risk adjusted, and comparisons may be used to benchmark performance. These data then inform quality improvement initiatives. CQRs require an overarching independent governance structure and surety of funding. CQRs rely upon whole of population enrolment to minimize the risk of selection bias, and often rely on the secondary use of sensitive health information, meaning that the processes for ethical review and consent to participation are different to clinical trials. Despite several local examples of CQR improving practice in Australia and Aotearoa New Zealand, providing substantial cost-benefit to the community, there remain significant barriers to CQR implementation and functions. These include the difficulty of accurate data capture, lack of a fit for purpose ethical review system, the constraints of existing Qualified Privilege legislations and the need for protected funding. Whilst the Australian Government has released a 10-year strategy for CQR reform, and the Aotearoa New Zealand Government has included registries in the planned Health New Zealand reforms for the public sector, we believe more urgent implementation of strategies to overcome these barriers is needed if CQRs are to have the impact on quality of care our Communities deserve.

ABSTRACT

BACKGROUND: Surgical conditions form a significant proportion of the global burden of disease. Since the 2015 World Health Assembly resolution A68.15, there is recognition that the provision of essential surgical care is an integral part of universal access to health care. The Lancet Commission on Global Surgery proposed its first surgical indicator to measure a population's access to the Bellwether procedures (laparotomy, caesarean section and treatment of open fracture) within two hours. Bellwether access is a proxy for emergency and essential surgical care. This project aims to map essential surgical access to the Bellwether procedures in Malaysia. METHODS: The location and capability of hospitals to perform the Bellwether procedures was obtained from the Ministry of Health (MoH) and MoH hospital specific websites. The Malaysian population data were retrieved from the national department of statistics. Times for patients to travel to hospital were calculated by combining manual contouring and geospatial mapping. RESULTS: There were 49 Bellwether-capable MoH hospitals serving a national population of 32.5 million. Overall 94% of Malaysia's population have access to the Bellwethers within two hours. This coverage is universal in West (Peninsular) Malaysia, but there is only 73% coverage in East Malaysia, with 1.8 million residents of Sabah and Sarawak not having timely access. Malaysia's Bellwether capacity compares well with other countries in World Health Organisation's Western Pacific region. CONCLUSION: There is good access to essential and emergency surgical services in Malaysia. The incomplete access for 1.8 million people in East Malaysia will inform national surgical planning.

ABSTRACT

BACKGROUND: There have been several reports that co-infection with the novel coronavirus severe acute respiratory syndrome coronavirus 2 at the time of surgery increases mortality. The aim of this study was to estimate the effect size of coronavirus disease 2019 (COVID-19) on post-operative mortality by performing a systematic review and meta-analysis of the literature. METHODS: A systematic review and meta-analysis of the literature was performed. A search was undertaken using electronic bibliographic databases MEDLINE, EMBASE, PubMed and Cochrane Library to identify eligible studies published from 1 November 2019 until 21 August 2020. Eligible papers for meta-analysis were those that provided mortality rates following elective and emergency surgery in both COVID-19 positive and negative patients. Forest plots and estimates of odds of death related to having COVID-19 were formed using MedCalc version 9.6 software. Funnel plots to assess for publication bias and heterogeneity were formed in Meta-Essentials. RESULTS: There were 140 records screened for inclusion. Full texts of 39 articles were reviewed, and 36 articles were included in the qualitative synthesis. There were eight studies eligible for meta-analysis. There was a total of 193 operations performed on patients with a concurrent COVID-19 infection and 910 performed on patients who were COVID-19 negative. The odds ratio for mortality in patients who underwent a surgical procedure while COVID-19 positive was 7.9 (95% confidence interval: 3.2-19.4). CONCLUSION: This meta-analysis confirms that concurrent COVID-19 infection increases the risk of surgical mortality. The magnitude of this risk mandates that strategies are developed to mitigate the risk at both an individual and system level.

ABSTRACT

This paper addresses the establishment of the Red Crescent, an equivalent of the Red Cross, in the Ottoman Empire in 1868 through the founding of 'the Society of Care and Aid for Wounded and Disabled Soldiers' (Mecrȗhȋnve Marzȃ-yi Askeriyeye Imdad ve Muavenet Cemiyeti). Following initial slow development, the Society was revitalized in April 1877 in preparation for war with Russia. Importantly, the 1877-1878 Ottoman-Russian conflict was the first major war conducted by signatories of the 1864 First Geneva Convention, which made provisions for the treatment of wounded and sick soldiers and protection for those providing care. Although both the Ottoman Empire and Russia were signatories, major issues remained to be resolved in practice and the heat of conflict. One of the unresolved issues was international and Russian recognition of a red crescent on a white background as a sign of neutrality, in addition to a red cross. An interim agreement was signed between the two sides with international support. Full international approval of the red crescent symbol took much longer and was only confirmed at the ninth Red Cross Conference in Washington in 1912, 35 years later. Today, the red crescent represents all majority Muslim countries' aid institutions.

ABSTRACT

BACKGROUND: Papua New Guinea, Pacific Island nations, and Timor-Leste represent a range of island nations with populations ranging from a few thousand to 8 million. They perform on average about 25% of the Lancet Commission of Global Surgery's target 5000 per 100 000 population and their health workforce have significant deficits of trained surgeons and anaesthetists. This study was conducted to determine how the current national health plans of these nations have included surgery and anaesthesia. METHODS: The most recent (as of December 2018) published national health plans of 10 Pacific Island nations (Cook Islands, Fiji, Nauru, Federated States of Micronesia, Kiribati, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu), Papua New Guinea and Timor-Leste were reviewed for content and process, searching for key words and identifying themes related to surgery and anaesthesia. RESULTS: There were 12 national health plans with a combined total of 478 pages. There was limited surgical and/or anaesthesia input within the planning process. Injuries, blindness, cancer and non-communicable diseases were included themes, but the potential role of surgical care in addressing these conditions was not well documented. The need for better information and registries was noted by several nations but possible surgical care delivery or outcome metrics were not included. CONCLUSION: There is limited mention of surgical and anaesthesia care planning within current health plans in the Pacific, PNG and TL. There is a need for greater surgical and anaesthesia engagement in future plans with performance measured against World Health Organization core surgical indicators.
