RESUMEN
OBJECTIVE: To determine the association between SAO workforce and mortality from emergent surgical and obstetric conditions within US HR Rs. BACKGROUND: SAO workforce per capita has been identified as a core metric of surgical capacity by the Lancet Commission on Global Surgery, but its utility has not been assessed at the subnational level for a high-income country. METHODS: The number of practicing surgeons, anesthesiologists, and obstetricians per capita was estimated for all HRRs using the US Health Resources & Services Administration Area Health Resource File Database. Deaths due to emergent general surgical and obstetric conditions were determined from the Center for Disease Control and Prevention WONDER database. We utilized B-spline quantile regression to model the relationship between SAO workforce and emergent surgical mortality at different quantiles of mortality and calculated the expected change in mortality associated with increases in SAO workforce. RESULTS: The median SAO workforce across all HRRs was 74.2 per 100,000 population (interquartile range 33.3-241.0). All HRRs met the Lancet Commission on Global Surgery lower target of 20 SAO per 100,000, and 97.7% met the upper target of 40 per 100,000. Nearly 2.8 million Americans lived in HRRs with fewer than 40 SAO per 100,000. Increases in SAO workforce were associated with decreases in surgical mortality in HRRs with high mortality, with minimal additional decreases in mortality above 60 to 80 SAO per 100,000. CONCLUSIONS: Increasing SAO workforce capacity may reduce emergent surgical and obstetric mortality in regions with high surgical mortality but diminishing returns may be seen above 60 to 80 SAO per 100,000. Trial Registration: N/A.

BACKGROUND: Diagnostic investigations, including pathology and laboratory medicine (PALM) and radiology, have been largely absent from international strategies such as the Sustainable Development Goals. Further, there is little international guidance on which health system tiers different diagnostics should be placed, a critical step in developing a country-level diagnostics network. We describe a modeling strategy to produce tier-specific diagnostic recommendations based on disease burden, current treatment pathways, and existing infrastructure in a country. METHODS: The relational model assumes that diagnostics should be available at the lowest tier where patients might receive medical management. Using Ghana as an exemplar, the 20 diseases forecasted by 2030 and 2040 to cause the greatest burden in low- and middle-income countries were mapped to three generalized tiers in the Ghanaian health system (Primary, Secondary, and Tertiary care) for three levels of each disease (triage, uncomplicated, and complicated). The lowest tier at which a diagnostic could potentially be placed was restricted by existing infrastructure, though placement still required there be a medical justification for the diagnostic at that tier. RESULTS: The model recommended 111 unique diagnostic investigations with 17 at Primary tier, an additional 45 at Secondary tier and a further 49 at Tertiary tier. Estimated capital costs were $8,330 at Primary tier and between $571,000 to $777,000 at Secondary tier. Twenty-eight different laboratory tests were recommended as send-outs from Primary to Secondary tier, and twelve as send-outs to Tertiary tier. CONCLUSIONS: This model provides a transparent framework within which countries can customize diagnostic planning to local disease priorities, health system patient treatment pathways, and infrastructural limitations to best support Universal Health Coverage.

OBJECTIVE: We review the existing research on environmentally sustainable surgical practices to enable SAO to advocate for improved environmental sustainability in operating rooms across the country. SUMMARY OF BACKGROUND DATA: Climate change refers to the impact of greenhouse gases emitted as a byproduct of human activities, trapped within our atmosphere and resulting in hotter and more variable climate patterns.1 As of 2013, the US healthcare industry was responsible for 9.8% of the country's emissions2; if it were itself a nation, US healthcare would rank 13th globally in emissions.3 As one of the most energy-intensive and wasteful areas of the hospital, ORs drive this trend. ORs are 3 to 6 times more energy intensive than clinical wards.4 Further, ORs and labor/delivery suites produce 50%-70% of waste across the hospital.5,6 Due to the adverse health impacts of climate change, the Lancet Climate Change Commission (2009) declared climate change "the biggest global health threat of the 21st century" and predicted it would exacerbate existing health disparities for minority groups, children and low socioeconomic patients.7. METHODS/RESULTS: We provide a comprehensive narrative review of published efforts to improve environmental sustainability in the OR while simultaneously achieving cost-savings, and highlight resources for clinicians interested in pursuing this work. CONCLUSION: Climate change adversely impacts patient health, and disproportionately impacts the most vulnerable patients. SAO contribute to the problem through their resource-intensive work in the OR and are uniquely positioned to lead efforts to improve the environmental sustainability of the OR.

BACKGROUND: Lung resection surgery can be a complementary therapy for managing tuberculosis (TB) complications, but access is lacking in high-burden areas. The referral process for surgical evaluation is not well described. This study aimed to elucidate the TB surgery referral process in Peru. METHODS: A qualitative study was conducted using focus groups and interviews of health care providers from the Peruvian National TB Program. A semi-structured interview guide was developed with local partners. Focus groups and individual interviews were recorded and transcribed. Thematic analysis was used to reconstruct the referral process and identify barriers as well as areas for improvement. RESULTS: A total of 12 sessions were recorded (7 interviews and 5 focus groups; 36 participants total). The main themes identified were: (1) Surgical referral workflow, (2) Unstandardized selection criteria for surgery, (3) Limited inter-institutional communication, and (4) Material barriers to surgical management. CONCLUSION: Health care providers involved in the referral process of surgical management of tuberculosis in Lima reported a hierarchical referral workflow. Interinstitutional communication may be a critical interventional point to improve a patient's quality of care during the referral process.

BACKGROUND: In resource-limited settings, there is a unique opportunity for using process improvement strategies to address the lack of access to surgical care. By implementing organizational changes in the surgical admission process, we aimed to decrease wait times, increase surgical volume, and improve patient satisfaction for elective general surgery procedures at a public tertiary hospital in Lima, Peru. METHODS: During the first phase of the intervention, Plan-Do-Study-Act (PDSA) cycles were performed to ensure the surgery waitlist included up-to-date clinical information. In the second phase, Lean Six Sigma methodology was used to adapt the admission and scheduling process for elective general surgery patients. After six months, outcomes were compared to baseline data using Wilcoxon rank-sum test. RESULTS: At the conclusion of phase one, 87.0% (488/561) of patients on the new waitlist had all relevant clinical data documented, improved from 13.3% (2/15) for the pre-existing list. Time from admission to discharge for all surgeries improved from 5 to 4 days (p<0.05) after the intervention. Median wait times from admission to operation for elective surgeries were unchanged at 4 days (p=0.076) pre- and post-intervention. There was a trend toward increased weekly elective surgical volume from a median of 9 to 13 cases (p=0.24) and increased patient satisfaction rates for elective surgery from 80.5 to 83.8% (p=0.62), although these were not statistically significant. CONCLUSION: The process for scheduling and admitting elective surgical patients became more efficient after our intervention. Time from admission to discharge for all surgical patients improved significantly. Other measured outcomes improved, though not with statistical significance. Main challenges included gaining buy-in from all participants and disruptions in surgical services from bed shortages.

BACKGROUND: Long travel times to reach essential surgical care in Chiapas, Mexico's poorest state, can delay lifesaving procedures and contribute to adverse outcomes. Geographical access to surgical facilities is 1 of the 6 indicators of the Lancet Commission on Global Surgery and has been measured extensively worldwide. Our objective is to determine the population with 2-h geographical access to facilities capable of performing the Bellwether procedures (laparotomy, cesarean delivery, and open fracture repair). This is the first study in Mexico to assess access to surgical facilities, including both the fragmented public sector and the private sector. METHODS: In this cross-sectional study, conducted from June 2019 to January 2020, Bellwether capable surgical facilities from all health systems in Chiapas were geocoded and assessed through on-site data collection, Ministry of Health databases, and verified via telephone. Geospatial analyses were performed on Redivis. RESULTS: We identified 59 Bellwether capable hospitals, with 17.5% (n = 954,460) of the state residing more than 2 h from surgical care in public and private health systems. Of those, 22 facilities had confirmed 24/7 Bellwether capability, and 23% (n = 1,178,383) of the affiliated population resided more than 2 h from these hospitals. CONCLUSIONS: Our study shows that the Ministry of Health and employment-based health coverage could provide timely access to essential surgical care for the majority of the population. However, the fragmentation of the healthcare system leaves a gap that contributes to delays in care and unmet emergency surgical needs.

INTRODUCTION AND HYPOTHESIS: Pelvic floor disorders (PFD) have a detrimental effect on quality of life. Despite the available treatments, women often do not seek medical care. Patient knowledge has been identified as a major barrier to accessing care. The objective of this study was to assess knowledge on PFD amongst women in Edmonton, hypothesizing that immigrant women are less knowledgeable about PFD than Canadian-born women. METHODS: A cross-sectional study of immigrant women and Canadian-born women was conducted. Immigrant women were recruited at the Multi-Cultural Health Brokers Co-op (MCHB) and Canadian-born women at a colposcopy clinic. The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) was administered. Scores for UI and POP were calculated and compared using a Mann-Whitney U test and a t test. A subgroup analysis of immigrants was carried out according to length of stay in Canada and ethnicity. Ethics approval was obtained from the University of Alberta Human Research Ethics Office. RESULTS: A total of 106 immigrants and 102 Canadian-born women completed the PIKQ. The overall PIKQ scores were 12.7 for immigrant women and 14.4 for Canadian-born women (p = 0.04). Immigrant women who had lived in Canada for >10 years had higher scores (mean = 13.2) compared with women with less than 10 years in Canada (mean = 11.8). Women from South Asia had higher overall PIKQ scores (mean = 14.6) whereas women from sub-Saharan Africa had the lowest scores (mean = 12.1). CONCLUSIONS: Immigrant women in Edmonton were found to have less knowledge on PFD than Canadian-born women.

BACKGROUND: Trauma is the leading cause of death among children and adolescents in Brazil. Measurement of quality of care is important, as well as interventions that will help optimize treatment. We aimed to evaluate adherence to standardized trauma care following the introduction of a checklist in one of the busiest Latin American trauma centers. MATERIAL AND METHODS: A prospective, non-randomized interventional trial was conducted. Assessment of children younger than age 15 was performed before and after the introduction of a checklist for trauma primary survey assessment. Over the study period, each trauma primary survey was observed and adherence to each step of a standardized primary assessment protocol was recorded. Clinical outcomes including mortality, admission to pediatric intensive-care units, use of blood products, mechanical ventilation, and number of CT scans in the first 24 h were also assessed. RESULTS: A total of 80 patients were observed (39 pre-intervention and 41 post-intervention). No statistically significant differences were observed between the pre- and post-intervention groups in regard to adherence to checklist by specialty (57.7% versus 50.5%, p = 0.115) and outcomes. No mortality was observed. CONCLUSION: In our trauma center, the quality of the adherence to standardized trauma assessment protocols is poor among both surgical and non-surgical providers. The quality of this assessment did not improve after the introduction of a checklist. Further work aimed at organizing the approach to pediatric trauma including triage and trauma education specifically for pediatric providers is needed.

BACKGROUND: All-cause perioperative mortality rate (POMR) is a commonly reported metric to assess surgical quality. Benchmarking POMR remains difficult due to differences in surgical volume and case mix combined with the burden of reporting and leveraging this complex and high-volume data. We seek to determine whether the pooled and individual procedure POMR of each bellwether (cesarean section, laparotomy, management of open fracture) correlate with state-level all-cause POMR in the interest of identifying benchmark procedures that can be used to make standardized regional comparisons of surgical quality. METHODS: The Brazilian National Healthcare Database (DATASUS) was queried to identify unadjusted all-cause POMR for all patient admissions among public hospitals in Brazil in 2018. Bellwether procedures were identified as any procedure involving laparotomy, cesarean section, or treatment of open long bone fracture and then classified as emergent or elective. The pooled POMR of all bellwether procedures as well as for each individual bellwether procedure was compared with the all-cause POMR in each of the 26 states, and one federal district and correlations were calculated. Funnel plots were used to compare surgical volume to perioperative mortality for each bellwether procedure. RESULTS: 4,756,642 surgical procedures were reported to DATASUS in 2018: 237,727 emergent procedures requiring laparotomy, 852,821 emergent cesarean sections, and 210,657 open, long bone fracture repairs. Pooled perioperative mortality for all of the bellwether procedures was correlated with all-procedure POMR among states (r = 0.77, p < 0.001). POMR for emergency procedures (2.4%) correlated with the all-procedure (emergent and elective) POMR (1.6%, r = 0.93, p < .001), while POMR for elective procedures (0.4%) did not (p = .247). POMR for emergency laparotomy (4.4%) correlated with all-procedure POMR (1.6%, r = 0.52, p = .005), as did the POMR for open, long bone fractures (0.8%, r = 0.61, p < .001). POMR for emergency cesarean section (0.05%) did not correlate with all-procedure POMR (p = 0.400). There was a correlation between surgical volume and emergency laparotomy POMR (r = - 0.53, p = .004), but not for emergency cesarean section or open, long bone fractures POMR. CONCLUSION: Procedure-specific POMR for laparotomy and open long bone fracture correlates modestly with all-procedure POMR among Brazilian states which is primarily driven by emergency procedure POMR. Selective reporting of emergency laparotomy and open fracture POMR may be a useful surrogate to guide subnational surgical policy decisions.

BACKGROUND: The rise in deaths attributed to opioid drugs has become a major public health problem in the United States and in the world. Minimally invasive surgery (MIS) is associated with a faster postoperative recovery and our aim was to investigate if the use of MIS was associated with lower odds of prolonged opioid prescriptions after major procedures. METHODS: Retrospective study using the IBM Watson Health Marketscan® Commerical Claims and Encounters Database investigating opioid-naïve cancer patients aged 18-64 who underwent open versus MIS radical prostatectomy (RP), partial colectomy (PC) or hysterectomy (HYS) from 2012 to 2017. Propensity weighted logistic regression analyses were used to estimate the independent effect of surgical approach on prolonged opioid prescriptions, defined as prescriptions within 91-180 days of surgery. RESULTS: Overall, 6838 patients underwent RP (MIS 85.5%), 4480 patients underwent PC (MIS 61.6%) and 1620 patients underwent HYS (MIS 41.8%). Approximately 70-80% of all patients had perioperative opioid prescriptions. In the weighted model, patients undergoing MIS were significantly less likely to have prolonged opioid prescriptions in all three surgery types (Odds Ratio [OR] 0.737, 95% Confidence Interval [CI] 0.595-0.914, p = 0.006; OR 0.728, 95% CI 0.600-0.882, p = 0.001; OR 0.655, 95% CI 0.466-0.920, p = 0.015, respectively). CONCLUSION: The use of the MIS was associated with lower odds of prolonged opioid prescription in all procedures examined. While additional studies such as clinical trials are needed for further confirmation, our findings need to be considered for patient counseling as postoperative differences between approaches do exist.

BACKGROUND: Lack of providers in surgery, anesthesia, and obstetrics (SAO) is a primary driver of limited surgical capacity worldwide. We aimed to identify predictors of entry into Surgery, Anesthesia, and Obstetrics and Gynecology (SAO) fields and preference of working in the public sector in Brazil which may help in profiling medical students for recruitment into these needed areas. METHODS: A questionnaire was applied to all Brazilian medical graduates registered with a Board of Medicine from 2014 to 2015. Twenty-three characteristics were analyzed. Logistic regression was used to determine predictors' influence on outcome. RESULTS: There were 4601 (28.2%) responders to the survey, of which 40.5% (CI 34.7-46.5%) plan to enter SAO careers. Of the 23 characteristics analyzed, eight differed significantly between those who planned to work in SAO and those who did not. Of those eight characteristics, just three were significant predictors in the regression model: preference for working in the hospital setting, having spent more than 70% of their clinical years in practical activities, and valuing the substantial earning potential. These three factors explained only 6.3% of the variance in SAO preference. Within the graduates who preferred SAO careers, there were only two predictors for working in the public sector ("preparatory time before medical school" and valuing "prestige/status"). CONCLUSIONS: Factors affecting specialty and sector choice are multifaceted and difficult to predict. Future programs to fill provider gaps should identify methods other than medical student profiling to assure specialty and sector needs are met.

The adhesion of Plasmodium falciparum-infected erythrocytes (IRBC) to receptors on different host cells plays a divergent yet critical role in determining the progression and outcome of the infection. Based on our ex vivo studies with clinical parasite isolates from adult Thai patients, we have previously proposed a paradigm for IRBC cytoadherence under physiological shear stress that consists of a recruitment cascade mediated largely by P-selectin, ICAM-1 and CD36 on primary human dermal microvascular endothelium (HDMEC). In addition, we detected post-adhesion signaling events involving Src family kinases and the adaptor protein p130CAS in endothelial cells that lead to CD36 clustering and cytoskeletal rearrangement which enhance the magnitude of the adhesive strength, allowing adherent IRBC to withstand shear stress of up to 20 dynes/cm². In this study, we addressed whether CD36 supports IRBC adhesion as part of an assembly of membrane receptors. Using a combination of flow chamber assay, atomic force and confocal microscopy, we showed for the first time by loss- and gain-of function assays that in the resting state, the integrin α5ß1 does not support adhesive interactions between IRBC and HDMEC. Upon IRBC adhesion to CD36, the integrin is recruited either passively as part of a molecular complex with CD36, or actively to the site of IRBC attachment through phosphorylation of Src family kinases, a process that is Ca²âº-dependent. Clustering of ß1 integrin is associated with an increase in IRBC recruitment as well as in adhesive strength after attachment (â¼40% in both cases). The adhesion of IRBC to a multimolecular complex on the surface of endothelial cells could be of critical importance in enabling adherent IRBC to withstand the high shear stress in the microcirculations. Targeting integrins may provide a novel approach to decrease IRBC cytoadherence to microvascular endothelium.

Background: Despite the assurance of universal health coverage, large disparities exist in access to surgery in the state of Chiapas. The purpose of this study was to determine the effectiveness of the surgical referral system at hospitals operated by the Ministry of Health in Chiapas. Methods: 13 variables were extracted from surgical referrals data from three public hospitals in Chiapas over a three-year period. Interviews were performed of health care workers involved in the referral system and surgical patients. The quantitative and qualitative data was analyzed convergently and reported using a narrative approach. Findings: In total, only 47.4% of referred patients requiring surgery received an operation. Requiring an elective, gynecological, or orthopedic surgery and each additional surgery cancellation were significantly associated with lower rates of receiving surgery. The impact of gender and surgical specialty, economic fragility of farmers, dependence upon economic resources to access care, pain leading people to seek care, and futility leading patients to abandon the public system were identified as main themes from the mixed methods analysis. Interpretation: Surgical referral patients in Chiapas struggle to navigate an inefficient and expensive system, leading to delayed care and forcing many patients to turn to the private health system. These mixed methods findings provide a detailed view of often overlooked limitations to universal health coverage in Chiapas. Moving forward, this knowledge must be applied to improve referral system coordination and provide hospitals with the necessary workforce, equipment, and protocols to ensure access to guaranteed care. Funding: Harvard University and the Abundance Fund provided funding for this project. Funding sources had no role in the writing of the manuscript or decision to submit it for publication.

RESUMEN
Academic global surgery is a rapidly growing field that aims to improve access to safe surgical care worldwide. However, no universally accepted competencies exist to inform this developing field. A consensus-based approach, with input from a diverse group of experts, is needed to identify essential competencies that will lead to standardization in this field. A task force was set up using snowball sampling to recruit a broad group of content and context experts in global surgical and perioperative care. A draft set of competencies was revised through the modified Delphi process with two rounds of anonymous input. A threshold of 80% consensus was used to determine whether a competency or sub-competency learning objective was relevant to the skillset needed within academic global surgery and perioperative care. A diverse task force recruited experts from 22 countries to participate in both rounds of the Delphi process. Of the n = 59 respondents completing both rounds of iterative polling, 63% were from low- or middle-income countries. After two rounds of anonymous feedback, participants reached consensus on nine core competencies and 31 sub-competency objectives. The greatest consensus pertained to competency in ethics and professionalism in global surgery (100%) with emphasis on justice, equity, and decolonization across multiple competencies. This Delphi process, with input from experts worldwide, identified nine competencies which can be used to develop standardized academic global surgery and perioperative care curricula worldwide. Further work needs to be done to validate these competencies and establish assessments to ensure that they are taught effectively.
RESUMEN
BACKGROUND AIMS: Identifying patients who spontaneously resolve cytomegalovirus (CMV) reactivation could spare these patients from the toxicity of antiviral drugs such as ganciclovir. The role of CMV-specific T cells in clearing CMV viremia in patients who do not receive ganciclovir has not been evaluated. We assessed this in patients with CMV viremia between 50 and 50 000 genome copies/mL, because our threshold for initiating ganciclovir is 50 000 copies/mL. METHODS: We enumerated CMV-specific T cells in 39 CMV seropositive hematopoietic cell transplantation (HCT) recipients within 4 days of the first positive CMV polymerase chain reaction (PCR). CMV-specific T cells were defined as cells that upon stimulation with CMV lysate or pp65 overlapping peptides produced interferon (IFN)-γ, tumor necrosis factor (TNF)-α or interleukin (IL)-2, alone or in combination. RESULTS: Among Donor (D+), Recipient (R+) patients, unifunctional CMV-specific CD4 T-cells were higher in patients who spontaneously resolved CMV viremia (did not receive ganciclovir) versus those who progressed (received ganciclovir) (median 0.20 versus 0.02/µL lysate-stimulated cells, P < 0.05, and 0.26 versus 0.05/µL pp65 peptide-stimulated cells, P<0.05). Among D- R+ patients, there was no difference between patients with spontaneous resolution or progression; all subsets of CMV-specific T cells measured were barely detectable, in both patients with spontaneous resolution and those with progression. CONCLUSIONS: Among D+ R+ patients (but not D- R+ patients), high CMV-specific CD4 T-cell counts identify patients who can spontaneously resolve CMV reactivation. In D- R+ patients, immune mechanisms other than T cells may control the progression from reactivation to high-level viremia/disease.

The objective of this study is to assess the cost-effectiveness of three different strategies with different availabilities of cesarean sections (CS). The setting was rural and urban areas of India with varying rates of CS and access to comprehensive emergency obstetric care (CEmOC) for women of reproductive age in India. Three strategies with different access to CEmOC and CS rates were evaluated: (A) India's national average (50.2% access, 17.2% CS rate), (B) rural areas (47.2% access, 12.8% CS rate) and(C) urban areas (55.7% access, 28.2% CS rate). We performed a first-order Monte Carlo simulation using a 1-year cycle time and 34-year time horizon. All inputs were derived from literature. A societal perspective was utilized with a willingness-to-pay threshold of $1,940. The outcome measures were costs and quality-adjusted life years were used to calculate the incremental cost-effectiveness ratio (ICER). Maternal and neonatal outcomes were calculated. Strategy C with the highest access to CEmOC despite the highest CS rate was cost-effective, with an ICER of 354.90. Two-way sensitivity analysis demonstrated this was driven by increased access to CEmOC. The highest CS rate strategy had the highest number of previa, accreta and ICU admissions. The strategy with the lowest access to CEmOC had the highest number of fistulae, uterine rupture, and stillbirths. In conclusion, morbidity and mortality result from lack of access to CEmOC and overuse of CS. While interventions are needed to address both, increasing access to surgical obstetric care drives cost-effectiveness and is paramount to optimize outcomes.
RESUMEN
Background: Chiapas is among the states with the lowest access to health care in Mexico. A better understanding of the role of interpersonal relationships in referral systems could improve access to care in the region. The purpose of this study was to analyze the underlying barriers and facilitators to accessing surgical care at public hospitals run by the Ministry of Health in Chiapas. Methods: In this qualitative interview study, we performed semi-structured interviews with 19 surgical patients and 18 healthcare workers at three public hospitals in the Fraylesca Region of Chiapas to explore barriers and facilitators to successfully accessing surgical treatment. Transcripts were coded and analyzed using an inductive, thematic approach to data analysis. Findings: The five major themes identified as barriers to surgical care were dehumanization of patients, the toll of rehumanizing patients, animosity in the system, the refraction of violence onto patients, and poor resource coordination. Three themes identified as facilitators to receiving care were teamwork, social capital, and accompaniment. Interpretation: Health care workers described a culture of demoralization and mistrust within the health system worsened by a scarcity of resources. As a result, patient care is hampered by conflict, miscommunication, and feelings of dehumanization. Efforts to improve access to surgical care in the region should consider strategies to improve teamwork and expand patient accompaniment. Funding: Harvard University and the Abundance Fund provided funding for this project. Funding sources had no role in the writing of the manuscript or decision to submit it for publication.Resumen. Antecedentes: Chiapas es uno de los estados en Mexico con el menor acceso a la atención médica, y a los servicios quirúrgicos. Una mejor comprensión del papel de las relaciones interpersonales en los sistemas de referencias podría mejorar el acceso a la atención medica en la región. El objetivo del estudio es analizar las barreras y facilitadores para acceder a la atención quirúrgica en los hospitales públicos pertenecientes a la Secretaria de Salud del estado de Chiapas. Método: En este estudio cualitativo, realizamos entrevistas semiestructuradas con 19 pacientes quirúrgicos y 18 trabajadores de la salud en tres hospitales públicos en la región de la Frailesca de Chiapas para explorar barreras y facilitadores para acceder al tratamiento quirúrgico. Las transcripciones se codificaron y analizaron utilizando un enfoque temático. Resultados: Las cinco barreras principales identificadas fueron la deshumanización de los pacientes, el costo a re humanizar pacientes, la animosidad en el sistema, la refracción de la violencia sobre los pacientes y la mala coordinación de recursos. Tres facilitadores para recibir cirugía fueron el trabajo en equipo, el capital social, y el acompañamiento. Interpretaciones: Los trabajadores de la salud describieron una cultura de desmoralización y desconfianza en el sistema de salud que se agrava con la escasez de recursos. Como resultado se obtiene, conflicto, falta de comunicación, y sentimientos de deshumanización que empeoran la atención al paciente. Recomendaciones para mejorar el acceso a los servicios quirúrgicos en la región incluyen estrategias para mejorar el trabajo en equipo y ampliar el acompañamiento de los pacientes. Financiamiento: La Universidad de Harvard y the Abundance Fund proporcionaron fondos para este proyecto. Las fuentes de financiamiento no influyen en la redacción ni en la publicación del manuscrito.
RESUMEN
INTRODUCTION: Many patients worldwide are unable to access timely primary repair of cleft lip and palate. The aim of this study was to assess patient-perceived barriers to accessing timely cleft lip and palate repair across Brazil. METHODS: A 29-item questionnaire was applied to patients undergoing surgery for cleft lip and/or palate across five contrasting sites in Brazil from February 2016 to November 2017. Differences in patient timelines, demographics, and patient-reported barriers were compared by region. A multivariate logistic regression was used to determine predictors of delayed care. RESULTS: Of 181 patients, 42% of patients received timely primary surgical repair. The age of the patient at the interview was 82 months (standard deviation [SD] 107) and 52% were male. The majority of delays occurred between diagnosis and primary surgical repair. The mean number of barriers to accessing timely surgical care cited by each patient was 3.77. The most common barrier was perceived "lack of hospitals that provided the surgery in my area" (48% (n = 86)). Univariate logistic regression showed increased odds of receiving late care in the state of Amazonas (odds ratio [OR] 2.91; 95% confidence interval [CI] 1.07-7.96; P = 0.037) or Para (OR 4.46; 95% CI 1.09-19.70; P = 0.037). Multivariate logistic regression determined predictors of delayed care to be female sex (OR = 2.05; 95% CI 1.05-3.99; P = 0.035) and perceived poor availability of care (OR = 0.045; 95% CI 1.02-4.37; P = 0.045). CONCLUSION: The majority of patients in Brazil are not receiving timely primary repair of their clefts. Improvements in the coordination of care, patient education and patient empowerment are required.
