Beyond the Expected: Evaluating Preoperative Predictors of a Difficult Cholecystectomy Aboard the USNS Comfort.

Mini abstract Typical preoperative markers of a difficult laparoscopic cholecystectomy did not apply during the US Naval ShipComfort Deployment in 2019. This prospective study reveals the importance of preparedness for short-term surgical missions, the impact of health care disparities on the severity of disease, and the need for deliberate and thoughtful engagement with host-nation partners.

Mistaken identity: Reporting two cases of rare forms of extrapulmonary tuberculosis in Solomon Islands.

INTRODUCTION AND IMPORTANCE: Extrapulmonary tuberculosis (EPTB) is a relatively rare and difficult-to-diagnose manifestation of Myobacterium tuberculosis (TB) infection. CASE PRESENTATION: This study reports the cases of a 47-year-old male and a 35-year old female with rare forms of EPTB who sought medical care in Solomon Islands. Both patients presented with nondescript symptoms and a chief complaint of pain. Initial diagnosis for the male and female patient was an abacterial colon polypoid mass and a urinary tract infection (UTI) respectively. Following unsuccessful treatment for UTI and further investigation, the surgical team diagnosed the female patient with a tuberculosis spondylitis and a bilateral psoas abscess. The male patient was subsequently diagnosed with isolated colonic tuberculosis. After starting medication, the patients were discharged and prescribed 9-month treatment regimens. During outpatient treatment both patients reported suboptimal adherence. The female patient resumed treatment and showed improvement while the male patient discontinued treatment, experienced worsening symptoms, and ultimately died. CLINICAL DISCUSSION: The nonspecific symptoms of extrapulmonary TB infection make it difficult to diagnose. Cases of rare forms of EPTB are particularly challenging to identify. Misdiagnosis may further increase the likelihood of mortality and morbidity in these cases. Intensive medication counseling, patient outreach, and regularly scheduled follow-up visits may reduce the incidence of poor adherence and reduce the risk of developing drug-resistant TB. CONCLUSION: Medical practitioners in tuberculosis-endemic countries like Solomon Islands should maintain a high clinical index of suspicion in diagnosing EPTB. Future research should investigate the prevalence of TB and EPTB in the Solomon Islands.

Building Capability and Capacity: The Establishment of an Oncology Unit in the Solomon Islands.

PURPOSE: To describe the establishment of an oncology unit at the National Referral Hospital (NRH) in the Solomon Islands, a low-income nation in the South Pacific. METHODS: A scoping visit was carried out in 2016 to assist in the development of coordinated cancer services and to establish a medical oncology unit at the NRH at the request of the Medical Superintendent. This was followed by an observership visit to Canberra by an NRH doctor training in oncology in 2017. After a request from the Solomon Islands Ministry of Health, the Australian Government Department of Foreign Affairs and Trade (DFAT) arranged an in-country multidisciplinary mission under the Royal Australasian College of Surgeons/Royal Australasian College of Physicians Pacific Islands Program to help in the commissioning of the NRH Medical Oncology Unit in September 2018. Staff training and education sessions were held. The team, with the assistance of an Australian Volunteers International Pharmacist, has helped the NRH staff to develop localized Solomon Islands Oncology Guidelines. Donated equipment and supplies have helped with the initial establishment of the service. A second DFAT Oncology mission visit was made in 2019 followed by two NRH oncology nurses visiting Canberra on observership later that year and support of the Solomon's doctor to pursue postgraduate education in cancer sciences. Ongoing mentorship and support has been maintained. RESULTS: The island nation now has a sustainable oncology unit delivering chemotherapy treatments and management of patients with cancer. CONCLUSION: A collaborative multidisciplinary team approach by professionals from the high-income country working with colleagues from the low-income nation with coordination of different stakeholders was the key to this successful initiative in improving cancer care.

Generating cause of death information to inform health policy: implementation of an automated verbal autopsy system in the Solomon Islands.

BACKGROUND: Good quality cause of death (COD) information is fundamental for formulating and evaluating public health policy; yet most deaths in developing countries, including the Solomon Islands, occur at home without medical certification of cause of death (MCCOD). As a result, COD data in such contexts are often of limited use for policy and planning. Verbal autopsies (VAs) are a cost-effective way of generating reliable COD information in populations lacking comprehensive MCCOD coverage, but this method has not previously been applied in the Solomon Islands. This study describes the establishment of a VA system to estimate the cause specific mortality fractions (CSMFs) for community deaths that are not medically certified in the Solomon Islands. METHODS: Automated VA methods (SmartVA) were introduced into the Solomon Islands in 2016. Trained data collectors (nurses) conducted VAs on eligible deaths to December 2020 using electronic tablet devices and VA responses were analysed using the Tariff 2.0 automated diagnostic algorithm. CSMFs were generated for both non-inpatient deaths in hospitals (i.e. 'dead on/by arrival') and community deaths. RESULTS: VA was applied to 914 adolescent-and-adult deaths with a median (IQR) age of 62 (45-75) years, 61% of whom were males. A specific COD could be diagnosed for more than 85% of deaths. The leading causes of death for both sexes combined were: ischemic heart disease (16.3%), stroke (13.5%), diabetes (8.1%), pneumonia (5.7%) and chronic-respiratory disease (4.8%). Stroke was the top-ranked cause for females, and ischaemic heart disease the leading cause for males. The CSMFs from the VAs were similar to Global Burden of Disease (GBD) estimates. Overall, non-communicable diseases (NCDs) accounted for 73% of adult deaths; communicable, maternal and nutritional conditions 15%, and injuries 12%. Six of the ten leading causes reported for facility deaths in the Solomon Islands were also identified as leading causes of community deaths based on the VA diagnoses. CONCLUSIONS: NCDs are the leading cause of adult deaths in the Solomon Islands. Automated VA methods are an effective means of generating reliable COD information for community deaths in the Solomon Islands and should be routinely incorporated into the national mortality surveillance system.

Diversity of epidemiological transition in the Pacific: Findings from the application of verbal autopsy in Papua New Guinea and the Solomon Islands.

BACKGROUND: Cause of death data are essential for rational health planning yet are not routinely available in Papua New Guinea (PNG) and Solomon Islands. Indirect estimation of cause of death patterns suggests these populations are epidemiologically similar, but such assessments are not based on direct evidence. METHODS: Verbal autopsy (VA) interviews were conducted at three sites in PNG and nationwide in Solomon Islands. Training courses were also facilitated to improve data from medical certificates of cause of death (MCCODs) in both countries. Data were categorised into broad groups of endemic and emerging conditions to aid assessment of the epidemiological transition. FINDINGS: Between 2017 and 2020, VAs were collected for 1,814 adult deaths in PNG and 819 adult deaths in Solomon Islands. MCCODs were analysed for 662 deaths in PNG and 1,408 deaths in Solomon Islands. The VA data suggest lower NCD mortality (48.8% versus 70.3%); higher infectious mortality (27.0% versus 18.3%) and higher injury mortality (24.5% versus 11.4%) in PNG compared to Solomon Islands. Higher infectious mortality in PNG was evident for both endemic and emerging infections. Higher NCD mortality in Solomon Islands reflected much higher emerging NCDs (43.6% vs 21.4% in PNG). A similar pattern was evident from the MCCOD data. INTERPRETATION: The cause of death patterns suggested by VA and MCCOD indicate that PNG is earlier in its epidemiological transition than Solomon Islands, with relatively higher infectious mortality and lower NCD mortality. Injury mortality was also particularly high in PNG.This study was funded by Bloomberg Philanthropies.

Comparison of two rapid diagnostic tests during a large dengue virus serotype 3 outbreak in the Solomon Islands in 2013.

Dengue virus (DENV) infection causes various clinical presentations, including asymptomatic infection, dengue with or without warning signs and severe dengue. An early and accurate diagnosis of DENV infection during the first few days of illness supports clinical management and significantly reduces dengue-associated mortality and morbidity. However, it is very difficult to confirm DENV infection in endemic regions without qualified dengue diagnostic laboratories. In this study, we evaluated the performance of two commercially available rapid diagnostic tests (RDTs) using serum samples collected in the Solomon Islands during the 2013 DENV-3 outbreak. The sensitivity and specificity of the tests were calculated by comparing the results of DENV nonstructural protein 1 (NS1), IgM and IgG RDTs with those obtained by qRT-PCR. We also compared the results of the DENV IgM/IgG RDT with those obtained using an IgM/IgG capture enzyme-linked immune-sorbent assay (ELISA). The sensitivities of the SD and CTK NS1 RDTs were similar (90.9% and 92.6%), and the specificity of the SD NS1 RDT was significantly higher than that of the CTK NS1 RDT (100% versus 78.8%). The inclusion of IgM and IgG in the RDT did not significantly increase the sensitivity for DENV diagnosis. Compared with the SD IgM RDT, IgM capture ELISA had the same specificity but higher sensitivity. User-friendly RDTs remain the first choice and the most convenient tool in dengue endemic regions, where laboratory facilities and the corresponding infrastructure are lacking. Our study provided important and practical information for comparing the performance and validity of the different RDTs for rapid dengue detection.

Surgical care in the Solomon Islands: a road map for universal surgical care delivery.

BACKGROUND: Access to surgical care and emergency obstetrical care is limited in low-income countries. The Solomon Islands is one of the poorest countries in the Pacific region. Access to surgical care in Solomon Islands is limited and severely affected by a country made up of islands. Surgical care is centralized to the National Referral Hospital (NRH) on Guadalcanal, leaving a void of care in the provinces where more than 80% of the people live. METHODS: To assess the ability to provide surgical care to the people living on outer islands in the Solomon Islands, the provincial hospitals were evaluated using the World Health Organization's Global Initiative for Emergency and Essential Surgical Care Needs Assessment Tool questionnaire. Data on infrastructure, workforce, and equipment available for treating surgical disease was collected at each provincial hospital visited. RESULTS: Surgical services are centralized to the NRH on Guadalcanal in Solomon Islands. Two provincial hospitals provide surgical care when a surgeon is available. Six of the hospitals evaluated provide only very basic surgical procedures. Infrastructure problems exist at every hospital including lack of running water, electricity, adequate diagnostic equipment, and surgical supplies. The number of surgeons and obstetricians employed by the Ministry of Health is currently inadequate for delivering care at the outer island hospitals. CONCLUSIONS: Shortages in the surgical workforce can be resolved in Solomon Islands with focused training of new graduates. Training surgeons locally, in the Pacific region, can minimize the "brain drain." Redistribution of surgeons and obstetricians to the provincial hospitals can be accomplished by creating supportive connections between these hospitals, the NRH, and international medical institutions.

Second opinions in remote surgical practice using email and digital photography.

BACKGROUND: Email offers the opportunity to improve communication between surgeons across the world. This experimental study aimed to assess the feasibility of obtaining clinical opinions by email and digital photography in remote surgical practice. METHODS: Over a 3-week period, all adult general surgical cases with a visual component to their condition admitted to a remote developing-world hospital were invited to participate. Clinical details and digital images were emailed to a UK general surgeon who consulted specialist colleagues if required and emailed back a suggested diagnosis and management plan, rating the confidence with which these were made on a five-point scale. The concordance between diagnoses and management plans from each centre were rated by three independent general surgeons. RESULTS: In this prospective study of 32 patients, 56% of diagnoses and 78% of management plans were made by the UK surgeons with 'high' or 'total' confidence. Causes of low diagnostic confidence included vague swellings and low-resolution X-ray images. Diagnostic and management concordance between centres was adjudged 'high' or 'total' in 88 and 43% of cases, respectively. CONCLUSION: Obtaining second opinions using email and digital photography is feasible in adult general surgery, but its efficacy is limited in cases where image resolution or non-visual clues are important.
