Burn Admissions Across Low- and Middle-income Countries: A Repeated Cross-sectional Survey

Burn injuries have decreased markedly in high-income countries while the incidence of burns remains high in Low- and Middle-Income Countries (LMICs) where more than 90% of burns are thought to occur. However, the cause of burns in LMIC is poorly documented. The aim was to document the causes of severe burns and the changes over time. A cross-sectional survey was completed for 2014 and 2019 in eight burn centers across Africa, Asia, and Latin America: Cairo, Nairobi, Ibadan, Johannesburg, Dhaka, Kathmandu, Sao Paulo, and Guadalajara. The information summarised included demographics of burn patients, location, cause, and outcomes of burns. In total, 15,344 patients were admitted across all centers, 37% of burns were women and 36% of burns were children. Burns occurred mostly in household settings (43–79%). In Dhaka and Kathmandu, occupational burns were also common (32 and 43%, respectively). Hot liquid and flame burns were most common while electric burns were also common in Dhaka and Sao Paulo. The type of flame burns varies by center and year, in Dhaka, 77% resulted from solid fuel in 2014 while 74% of burns resulted from Liquefied Petroleum Gas in 2019. In Nairobi, a large proportion (32%) of burns were intentional self-harm or assault. The average length of stay in hospitals decreased from 2014 to 2019. The percentage of deaths ranged from 5% to 24%. Our data provide important information on the causes of severe burns which can provide guidance in how to approach the development of burn injury prevention programs in LMIC.

Impact of a Novel Social Work Program on Access to Tertiary Care

Background: In the movement for global health equity, increased research and funding have not yet addressed a shortage of evidence on effectively implementing context-specific interventions; one unmet need is facilitating access to specialty care within the public health sector in Mexico. Compañeros en Salud has been piloting a novel program, called Right to Healthcare (RTHC), to increase access to specialty care for the rural poor in Chiapas, Mexico. The RTHC program incorporates social work, patient navigation, referrals, direct economic support, and accompaniment for patients.

Objectives: This study evaluates the effectiveness of the RTHC program. Primary outcomes analyzed included acceptance of any referral and attendance of any appointment. Secondary outcomes included acceptance of the first referral and rate of appointment attendance for patients with an accepted referral.

Methods: Using referral process data for the years 2014 to 2019 from a public tertiary care hospital in Chiapas, 91 RTHC patients were matched using 2:1 optimal pair matching with a control cohort balancing covariates of patient age, sex, specialty referred to, level of referring hospital, and municipality.

Findings: RTHC patients were more likely to have had an accepted referral (OR 17.42, 95% CI 3.68 to 414.16) and to have attended an appointment (OR 5.49, 95% CI 2.93 to 11.60) compared to the matched control group. RTHC patients were also more likely to have had their first referral accepted (OR 2.78, 95% CI 1.29 to 6.73). Among patients with an accepted referral, RTHC patients were more likely to have attended an appointment (OR 3.86, 95% CI 1.90 to 8.57).

Conclusions: The results demonstrate that the RTHC model is successful in increasing access to specialty care by both increasing referral acceptance and appointment attendance.

COVID-19 and resilience of healthcare systems in ten countries

Declines in health service use during the Coronavirus Disease 2019 (COVID-19) pandemic could have important effects on population health. In this study, we used an interrupted time series design to assess the immediate effect of the pandemic on 31 health services in two low-income (Ethiopia and Haiti), six middle-income (Ghana, Lao People’s Democratic Republic, Mexico, Nepal, South Africa and Thailand) and high-income (Chile and South Korea) countries. Despite efforts to maintain health services, disruptions of varying magnitude and duration were found in every country, with no clear patterns by country income group or pandemic intensity. Disruptions in health services often preceded COVID-19 waves. Cancer screenings, TB screening and detection and HIV testing were most affected (26–96% declines). Total outpatient visits declined by 9–40% at national levels and remained lower than predicted by the end of 2020. Maternal health services were disrupted in approximately half of the countries, with declines ranging from 5% to 33%. Child vaccinations were disrupted for shorter periods, but we estimate that catch-up campaigns might not have reached all children missed. By contrast, provision of antiretrovirals for HIV was not affected. By the end of 2020, substantial disruptions remained in half of the countries. Preliminary data for 2021 indicate that disruptions likely persisted. Although a portion of the declines observed might result from decreased needs during lockdowns (from fewer infectious illnesses or injuries), a larger share likely reflects a shortfall of health system resilience. Countries must plan to compensate for missed healthcare during the current pandemic and invest in strategies for better health system resilience for future emergencies.

Low-dose diethylstilbestrol for heavily pretreated metastatic castration-resistant prostate cancer

Background:

Diethylstilbestrol (DES) at low doses is effective in metastatic castration resistant prostate cancer (mCRPC), understudied in the context of currently available treatments. We describe the efficacy and tolerability of low doses of DES for patients with heavily pretreated mCRPC.

Material and methods:

Single center retrospective cohort of patients with mCRPC treated with low dose DES between 2005 and 2020.

Results:

Thirty-four patients were evaluated, with a median age of 74 years (range 56-94), and a median of 3 previous treatment lines (range 1-7). 64.7% had received chemotherapy. A biochemical response was achieved in 10/32 patients (31.3%). Median progression free survival was 3.7 months. Median overall survival (OS) was 9.7 months. The most common adverse events were fatigue, gynecomastia, and nausea. Two deaths occurred due to arterial thrombosis.

Conclusions:

Low dose DES remains active in highly pretreated patients, with median PFS comparable to other available treatments. Patient selection is important for treatment safety.

Has Latin America achieved universal health coverage yet? Lessons from four countries

Background
Seven years after the commitment to United Nations’ call for Universal Health Coverage, healthcare services in Argentina, Brazil, Colombia, Mexico are generally accessible and affordable; but they still struggle to meet population health demands and address the rising health care costs. We aim to describe measures taken by these four countries to commit by Universal Health Coverage, addressing their barriers and challenges.

Methods
Scoping literature review, supplemented with targeted stakeholders survey.

Results
The four countries analysed achieved an overall index of essential coverage of 76–77%, and households out of pocket health expenditures fall below 25%. Services coverage was improved by expanding access to primary healthcare systems and coverage for non-communicable diseases, while provided community outreach by the increase in the number of skilled healthcare workers. New pharmaceutical support programs provided access to treatments for chronic conditions at zero cost, while high-costs drugs and cancer treatments were partially guaranteed. However, the countries lack with effective financial protection mechanisms, that continue to increase out of pocket expenditure as noted by lowest financial protection scores, and lack of effective financial mechanisms besides cash transfers.

Conclusions
Argentina, Brazil, Colombia, and Mexico have made progress towards UHC. Although, better financial protection is urgently required.

Lessons for Latin America from Mexico’s Experience With Patient Safety and Covid Response

Globally, more than 1 in 10 patients continue to be harmed due to safety lapses during their care.[1] Unsafe care results in over three million deaths each year. The health burden of harm is estimated at 64 million Disability-Adjusted Life Years (DALYs) per year similar to that of HIV/AIDS. Most of this burden is in low- and middle-income countries (LMICs). Recent estimates suggest that as many as 4 in 100 people die from unsafe care in the developing world [1]. The COVID-19 pandemic has clearly shown the risk of patient harm. The estimated proportion of hospital-acquired COVID-19 cases ranges from 12.5% to 44% [1]. As many as one third of these cases are reported to be among healthcare staff.
In Mexico, the Patient Safety journey started in 2002, with the National Crusade for Quality in Health Care,[2] the first Quality Policy in Latin America. The efforts to improve patient safety in Mexico can be divided into three distinct waves. A fourth wave has commenced with the pandemic. These lessons on patient safety are even more important now in the COVID era and can be applied in the region and elsewher

Improving Pediatric Neuro-Oncology Survival Disparities in the United States–Mexico Border Region: A Cross-Border Initiative Between San Diego, California, and Tijuana, Mexico

PURPOSE
Treatment of children with CNS tumors (CNSTs) demands a complex, interdisciplinary approach that is rarely available in low- and middle-income countries. We established the Cross-Border Neuro-Oncology Program (CBNP) between Rady Children’s Hospital, San Diego (RCHSD), and Hospital General, Tijuana (HGT), Mexico, to provide access to neuro-oncology care, including neurosurgic services, for children with CNSTs diagnosed at HGT. Our purpose was to assess the feasibility of the CBNP across the United States-Mexico border and improve survival for children with CNSTs at HGT by implementing the CBNP.

PATIENTS AND METHODS
We prospectively assessed clinicopathologic profiles, the extent of resection, progression-free survival, and overall survival (OS) in children with CNSTs at HGT from 2010 to 2017.

RESULTS
Sixty patients with CNSTs participated in the CBNP during the study period. The most common diagnoses were low-grade glioma (24.5%) and medulloblastoma (22.4%). Of patients who were eligible for surgery, 49 underwent resection at RCHSD and returned to HGT for collaborative management. Gross total resection was achieved in 78% of cases at RCHSD compared with 0% at HGT (P < .001) and was a predictor of 5-year OS (hazard ratio, 0.250; 95% CI, 0.067 to 0.934; P = .024). Five-year OS improved from 0% before 2010 to 52% in 2017. CONCLUSION The CBNP facilitated access to complex neuro-oncology care for underserved children in Mexico through binational exchanges of resources and expertise. Survival for patients in the CBNP dramatically improved. Gross total resection at RCHSD was associated with higher OS, highlighting the critical role of experienced neurosurgeons in the treatment of CNSTs. The CBNP model offers an attractive alternative for children with CNSTs in low- and middle-income countries who require complex neuro-oncology care, particularly those in close proximity to institutions in high-income countries with extensive neuro-oncology expertise.

Assessment of diagnostics capacity in hospitals providing surgical care in two Latin American states

Background
Diagnostic services are an essential component of high-quality surgical, anesthesia and obstetric (SAO) care. Efforts to scale up SAO care in Latin America have often overlooked diagnostics capacity. This study aims to analyze the capacity of diagnostic services, including radiology, pathology, and laboratory medicine, in hospitals providing SAO care in the states of Chiapas, Mexico and Amazonas, Brazil.

Methods
A stratified cross-sectional evaluation of diagnostic capacity in hospitals performing surgery in Chiapas and Amazonas was performed using the Surgical Assessment Tool (SAT). National data sources were queried for indicators of diagnostics capacity in terms of workforce, infrastructure and diagnosis utilization. Fisher’s exact tests and chi-square tests were used to compare categorical variables between the private and public sector in Chiapas while descriptive statistics are used to compare Amazonas and Chiapas.

Findings
In Chiapas, 53% (n = 17) of public and 34% (n = 20) of private hospitals providing SAO care were assessed. More private hospitals than public hospitals could always provide x-rays (35% vs 23.5%) and ultrasound (85% vs 47.1%). However neither sector could consistently perform basic laboratory testing such as complete blood counts (70.6% public, 65% private). In Amazonas, 30% (n = 18) of rural hospitals were surveyed. Most had functioning x-ray machine (77.8%) and ultrasound (55.6%). The majority of hospitals could provide complete blood count (66.7%) but only one hospital (5.6%) could always perform an infectious panel. Both Chiapas and Amazonas had dramatically fewer diagnostic practitioners per capita in each state compared to the national average capacity.

Interpretation
Facilities providing SAO care in low-resource states in Mexico and Brazil often lack functioning diagnostics services and workforce. Scale-up of diagnostic services is essential to improve SAO care and should occur with emphasis on equitable and adequate resource allocation.

Venoarterial extracorporeal membrane oxygenation in heart surgery post-operative pediatric patients: A retrospective study at Christus Muguerza Hospital, Monterrey, Mexico

Objectives:
Extracorporeal membrane oxygenation is a life support procedure developed to offer cardiorespiratory support when conventional therapies have failed. The purpose of this study is to describe the findings during the first years using venoarterial extracorporeal membrane oxygenation in pediatric patients after cardiovascular surgery at Christus Muguerza High Specialty Hospital in Monterrey, Mexico.

Methods:
This is a retrospective, observational, and descriptive study. The files of congenital heart surgery post-operative pediatric patients, who were treated with venoarterial extracorporeal membrane oxygenation from January 2013 to December 2015, were reviewed.

Results:
A total of 11 patients were reviewed, of which 7 (63.8%) were neonates and 4 (36.7%) were in pediatric age. The most common diagnoses were transposition of great vessels, pulmonary stenosis, and tetralogy of Fallot. Survival rate was 54.5% and average life span was 6.3 days; the main complications were sepsis (36.3%), acute renal failure (36.3%), and severe cerebral hemorrhage (9.1%). The main causes of death were multi-organ dysfunction syndrome (27.3%) and cerebral hemorrhage (18.2%).

Conclusion:
The mortality rates found are very similar to those found in a meta-analysis report published in 2013 and the main complication and causes of death are also very similar to the majority of extracorporeal membrane oxygenation reports for these kinds of patients. Although the results are encouraging, early sepsis detection, prevention of cerebral hemorrhage, and renal function monitoring must be improved.

Delays to diagnosis and barriers to care for breast cancer in Mexico and Peru: a cross sectional study

Background
Delays to breast cancer diagnosis and treatment initiation are associated with worsened outcomes. However, population-based screening is impractical in many low-income and middle-income countries (LMICs) because of resource constraints and a lack of capacity to effectively diagnose and treat screen-detected disease. Mexico and Peru have similar mortality-to-incidence ratios for breast cancer. Unlike Peru, Mexico has attempted to implement mammography screening, although it remains opportunistic with low (20%) national coverage rates. The aim of this study was to compare delays and describe barriers to care among breast cancer patients in Mexico and Peru.

Methods
This international cross-sectional study included breast cancer patients interviewed at four public cancer hospitals in Mexico City between 2009 and 2011, and a federally-funded regional cancer institute in Trujillo, Peru in 2015. A Breast Cancer Delays Questionnaire, developed and validated in Mexico and modified for Peru, was administered to breast cancer patients during routine hospital visits at each location. Patient-related, diagnostic, and treatment delays were quantified, and barriers to care identified.

Findings
We included data from 597 Mexican women and 113 Peruvian women. Age at diagnosis did not differ between countries (53 years [Mexico] vs 54 years [Peru], p=0·266). Most women in both countries had breast cancer detected by symptoms (84% [Mexico] vs 93% [Peru]; p<0·001), although more women in Mexico were diagnosed by mammography screening (12% vs 6%) and screening clinical breast examination (4% vs 1%). Of patients with available stage information, the majority of disease was AJCC stage II or III at diagnosis (76% [n=597, Mexico] vs 91% [93, Peru]; p=0·014). More women in Mexico were diagnosed at an early stage (AJCC stage 0 or I) (14% [Mexico] vs 4% [Peru]). Total delay (symptom discovery or screening to initiation of treatment) did not differ between the two countries (median 210 days [IQR 128–415; n=597] Mexico vs 201 days [82–442; n=74] Peru; [p=0·71]). Diagnostic delay (first medical consultation to diagnosis) was the greatest contributor to overall delay (113 days [59–250; n=597, Mexico] vs 174 days [40–396; n=95, Peru]; p=0·105). Approximately 60% of all patients had diagnostic delays greater than 3 months. Less than half (44%) of Mexican patients visited more than two health-care facilities before the cancer centre, compared with 71% of Peruvian patients (p<0·001). Patients in both countries reported that barriers to prompt arrival at the cancer centre were: not knowing where to go, lack of money, spread out appointments, and diagnostic errors.

Interpretation
Improved diagnostic and referral systems are necessary to reduce delays to breast cancer care in Mexico and Peru. Such improvements are prerequisites to the establishment of maximally effective mammography screening programmes in LMICs.
