Abstract
OBJECTIVES The objective of this study was to identify the association between healthcare fragmentation and survival for patients with colorectal cancer in Colombia. METHODS A retrospective cohort study was performed using administrative databases, with an electronic algorithm to identify patients with colorectal cancer based on codes. The patients were enrolled between January 1, 2013, and December 31, 2016. The exposure variable was fragmentation, which was measured based on the number of different healthcare institutions that treated a patient during the first year after diagnosis. Matching was performed using propensity scores to control for confounding, and the hazard ratio for exposure to higher fragmentation was calculated for the matched sample. RESULTS A total of 5036 patients with colorectal cancer were identified, 2525 (49.88%) of whom were women. The mean number of network healthcare institutions for the total sample was 5.71 (SD 1.98). The patients in the quartile with higher fragmentation had the highest mortality rate, 35.67 (95% CI 33.63-38.06) per 100 patients. The comparison of higher and lower quartiles of fragmentation resulted in an incidence rate ratio of 1.23 (95% CI 1.04-1.45; P = .02). Of the 5036 patients, 422 (8.38%) were classified as the exposed cohort (higher fragmentation). The total matched sample consisted of 844 subjects, and an HR of 1.26 (95%CI; 1.05-1.51) was estimated. CONCLUSIONS Exposure to more highly fragmented healthcare networks decreases overall 4-year survival for patients with colorectal cancer in Colombia.

Abstract
INTRODUCTION The use of comprehensive genomic profiling (CGP) and target therapies is associated with substantial improvements in clinical outcomes among patients with non-small cell lung cancer (NSCLC). However, the costs of CGP may increase the financial pressures of NSCLC on health systems worldwide, especially in low- and middle-income countries. This study aimed to estimate the cost-effectiveness of CGP compared with current genomic tests in patients with NSCLC from the perspective of the Colombian Health System. METHODS To estimate the costs and benefits of CGP and its comparators, we developed a 2-stage cohort model with a lifetime horizon. In the first stage, we made up a decision tree that calculated the probability of receiving each therapy as result of identifying a specific, actionable target. In the second stage, we developed a partitioned survival model that estimated the time spent at each health state. Incremental cost-effectiveness ratios were calculated for life-years (LYs) and quality-adjusted LYs gained. All costs were expressed in 2019 international dollars (INT$). RESULTS CGP is associated with gains of 0.06 LYs and 0.04 quality-adjusted LYs compared with current genomic tests. Incremental cost-effectiveness ratios for CGP ranged from INT$861 to INT$7848, depending on the outcome and the comparator. Sensitivity analyses show that the cost-effectiveness decision was sensitive to prices of CGP above INT$7170 per test. These results are robust to most deterministic and probabilistic sensitivity analyses. CONCLUSIONS CGP may be cost-effective in patients with NSCLC from the perspective of the Colombian Health System (societal willingness-to-pay threshold of INT$15 630 to INT$46 890).

Abstract
The aim of this study was to describe the three-dimensional orientation of the native anterior cruciate ligament (ACL) in magnetic resonance imaging (MRI) by calculating the angles of inclination in relation to the axial plane which is given for the knee joint line in a group of healthy individuals. These could help to establish guidelines that may be used for the surgical positioning of bone tunnels during ACL reconstruction. A total of 290 MRI scans of patients with integrity of the ACL were evaluated; three observers identified the coordinates of the femoral and tibial insertion sites, then it is defined the vector and evaluated its angles with respect to axial axis and calculated the angles with trigonometric equations. The data were analyzed according to the age, sex, side, BMI, and height of the patients, and the interobserver reliability was calculated. The patient demographics were as follows: age average: 45 years old, BMI average: 27.1, 54% right knees, and 60% female. The average angle for all the measurements was 76.95 degrees (SD ± 6.8 degrees) in the sagittal plane, 81.65 degrees (SD ± 7.79 degrees) in the coronal plane and 33.17 degrees (SD ± 4.98 degrees) in the axial plane. No statistically significant differences were found between the categorical variables mentioned; moderate to substantial interobserver reliability strength was found with an average kappa of 0.791 for all measurements. The three-dimensional orientation of the native ACL in a group of healthy individuals was established. The findings can be helpful for performing anatomical reconstructions of the ACL in injured patients using as reference the average calculated angles, or measure of the contralateral non-injured knee for surgical planning; these results serve as a basis for the design of a technique that optimizes the three-dimensional position of the ACL when it undergoes reconstruction in the trend toward greater precision for better functional results. Biomechanical and clinical-surgical studies are required to further evaluate our results.

Abstract
BACKGROUND The effect of teaching hospital status on cardiovascular surgery has been of common interest in recent decades, yet its magnitude on heart valve replacement is still a matter of debate. Given the ethical and practical unfeasibility of randomly assigning a patient to such an exposure, we use the inverse probability of treatment weighting (IPTW) to assess this marginal effect on the survival of Colombian patients who underwent a first heart valve replacement between 2016 and 2019. METHODS A retrospective cohort study was conducted based on administrative records. The time-to-death event and cumulative incidences of death, readmission, and reoperation are presented as outcomes. An artificial sample is configured through IPTW, adjusting for sociodemographic variables, comorbidities, technique, and intervention weight. RESULTS Of a sample of 3,517 patients, 1,051 (29.9%) were operated on in a teaching hospital. The median age was 65.0 (18.1-91.5), 38.5% of patients were ≤60, and 6.9% were ≥80. The cumulative incidences of death at 30, 90 days, and one year were 5.9%, 8%, and 10.9%, respectively. Furthermore, 23.5% of the patients were readmitted within 90 days and 3.6% underwent reintervention within one year. The odds of 30-day mortality are lower for patients operated in a teaching hospital (OR 0.51; 95% CI 0.29-0.92); however, no effect on survival was identified in terms of time-to-event of death (HR 1.07; 95%CI 0.78-1.46). CONCLUSIONS After IPTW, the odds of 30-day mortality are lower for patients operated in a teaching hospital. There was no effect on survival, 90-day or one-year mortality, 90-day readmission, or one-year reintervention. Together, we offer an opening for investigating an exposure that has yet to be explored in Latin America with potential value to understand teaching hospitals as the essential nature of reality of an academic-clinical synergy.

Abstract
BACKGROUND There are no information in the literature associating the volume of gastrectomies with survival and costs for the health system in the treatment of patients with gastric cancer in Colombia. AIMS The aim of this study was to analyze how gastrectomy for gastric cancer is associated with hospital volume, 30-day and 180-day postoperative mortality, and healthcare costs in Bogotá, Colombia. METHODS A retrospective cohort study based on hospital data of all adult patients with gastric cancer who underwent gastrectomy between 2014 and 2016 using a paired propensity score. The surgical volume was identified as the average annual number of gastrectomies performed by the hospital. RESULTS A total of 743 patients were included in the study. Hospital mortality at 30 and 180 days postoperatively was 36 (4.85%) and 127 (17.09%) patients, respectively. The average health care cost was USD 3,200. A total of 26 or more surgeries were determined to be the high surgical volume cutoff. Patients operated on in hospitals with a high surgical volume had lower 6-month mortality (HR 0.44; 95%CI 0.27-0.71; p=0.001), and no differences were found in health costs (mean difference 398.38; 95%CI-418.93-1,215.69; p=0.339). CONCLUSIONS This study concluded that in Bogotá (Colombia), surgery in a high-volume hospital is associated with better 6-month survival and no additional costs to the health system.

Abstract
BACKGROUND Major disparities in complications and mortality after appendectomy between countries with different income levels have not been well characterized, as comparative studies at patient level between countries are scant. This study aimed to investigate variations in postoperative complications, mortality, and failure to rescue after appendectomy between a high-income country and a low-to-middle-income country. METHODS Hospital discharges on adult patients who underwent appendectomy were extracted from administrative databases from Colombia and 2 states of the United States (Florida and New York). Outcomes included major postoperative complications, in-hospital mortality, and failure to rescue. Univariate analyses were conducted to compare outcomes between the 2 countries. Multivariable logistic regression analyses were conducted to examine the independent effect of country on outcomes after adjustment for patient age, sex, comorbidity index, severity of appendicitis, and appendectomy route (laparoscopic/open). RESULTS A total of 62,338 cases from Colombia and 57,987 from the United States were included in the analysis. Patients in Colombia were significantly younger and healthier but had a higher incidence of peritonitis. Use of laparoscopy was significantly lower in Colombia (5.9% vs 89.4%; P < .0001). After adjustment for covariates, multivariable logistic regression analyses revealed that compared to the United States, Colombia had lower complication rates (2.8% vs 6.6%; odds ratio [OR], 0.41; 95% confidence interval [CI], 0.39-0.44; P < .0001) but higher mortality (0.44% vs 0.08%; OR, 8.92; 95% CI, 5.69-13.98; P < .0001) and failure to rescue (13.6% vs 1.0%; OR, 17.01; 95% CI, 10.66-27.16; P < .0001). CONCLUSIONS Despite lower rates of postoperative complications, in-hospital mortality after appendectomy was higher in Colombia than in the United States. This difference may be explained by higher rates of failure to rescue in the low-to-middle-income country (ie, decreased ability of Colombian hospitals to rescue patients from complications).

Abstract
Aim To determine the impact of bloodstream infection (BSI) and other risk factors for mortality in patients with COVID-19 admitted to the intensive care unit (ICU). Methods A retrospective cohort was carried out at the Hospital Universitario Nacional (HUN) between March 29 and December 19, 2020. Patients with COVID-19 admitted to the Intensive Care Unit (ICU) were paired 1:4 in two groups, one with BSI and the other without, according to hospital stay and the month of admission. The primary outcome was mortality at 28 days. A Cox proportional hazards model was used to estimate differences in mortality risk. Results 456 patients were identified and 320 were included in the final cohort, 18% (n = 59) in the BSI group and 82% (n = 261) in the control group. 125 (39%) patients died, 30 (51%) in the BSI group and 95 (36%) in the control group (P = 0.040). BSI was associated with an increased risk of in-hospital mortality at 28 days, [HR] 1.77 (95% CI: 1.03-3.02; P = 0.037). Invasive mechanical ventilation (IMV) and age were associated with increased mortality risk. Some months of the year of the hospital stay were associated with a reduced risk of mortality. There was no difference in mortality between inappropriate and appropriate empirical antimicrobial use. Conclusion BSI in patients with COVID-19 in ICU increases in-hospital mortality to 28 days. Other risk factors for mortality were IMV and age.

Abstract
BACKGROUND Birth outcomes could have been affected by the COVID-19 pandemic through changes in access to prenatal services and other pathways. The aim of this study was to examine the effects of the COVID-19 pandemic on fetal death, birth weight, gestational age, number of prenatal visits, and caesarean delivery in 2020 in Colombia. METHODS We conducted a secondary analysis of data on 3,140,010 pregnancies and 2,993,534 live births from population-based birth certificate and fetal death certificate records in Colombia between 2016 and 2020. Outcomes were compared separately for each month during 2020 with the same month in 2019 and pre-pandemic trends were examined in regression models controlling for maternal age, educational level, marital status, type of health insurance, place of residence (urban/rural), municipality of birth, and the number of pregnancies the mother has had before last pregnancy. RESULTS We found some evidence for a decline in miscarriage risk in some months after the pandemic start, while there was an apparent lagging increase in stillbirth risk, although not statistically significant after correction for multiple comparisons. Birth weight increased during the onset of the pandemic, a change that does not appear to be driven by pre-pandemic trends. Specifically, mean birth weight was higher in 2020 than 2019 for births in April through December by about 12 to 21 g (p < 0.01). There was also a lower risk of gestational age at/below 37 weeks in 2020 for two months following the pandemic (April, June), but a higher risk in October. Finally, there was a decline in prenatal visits in 2020 especially in June-October, but no evidence of a change in C-section delivery. CONCLUSIONS The study findings suggest mixed early effects of the pandemic on perinatal outcomes and prenatal care utilization in Colombia. While there was a significant decline in prenatal visits, other factors may have had counter effects on perinatal health including an increase in birth weight on average.

Abstract
PURPOSE Breast cancer care requires a multimodal approach and a multidisciplinary team who must work together to obtain good clinical results. The fragmentation of care can affect the breast cancer care; however, it has not been measured in a low-resource setting. The aim of this study was to identify fragmentation of care, the geographic variation of this and its association with 4-year overall survival (OS), and costs of care for patients with breast cancer enrolled in Colombia's contributory health care system. MATERIALS AND METHODS A retrospective cohort study was conducted using administrative databases. Women with breast cancer who were treated from January 1, 2013, to December 31, 2015, were included. Fragmentation of care was the exposure, which was measured by the number of different health care provider institutions (HCPIs) that treated a patient during the first year after diagnosis. Crude mortality rates were estimated, survival functions were calculated using the nonparametric Kaplan-Meier approach, and adjusted hazard ratios (HRs) were estimated using multivariate Cox regression model to identify the association of fragmentation with 4-year OS. The association between fragmentation and costs of care was assessed using a multivariate linear regression model. RESULTS A total of 10,999 patients with breast cancer were identified, and 1,332 deaths were observed. The 4-year crude mortality rate was 31.97 (95% CI, 30.25 to 33.69) per 1,000 person-years for the whole cohort, and the highest rate was in the cohort defined for the fourth quartile of the fragmentation measurement (eight or more HCPIs), 40.94 (95% CI, 36.49 to 45.39). The adjusted HR for 4-year OS was 1.04 (95% CI, 1.01 to 1.07) for each HCPI additional. The cost of care is increased for each additional HCPIs (cost ratio, 1.25; 95% CI, 1.23 to 1.26). CONCLUSION Fragmentation of care decreases overall 4-year OS and increases the costs of care in women with breast cancer for Colombia.

Abstract
Reliable, timely and detailed information on lung cancer prevalence, mortality and costs from middle-income countries is essential to policy design. Thus, we aimed to develop an electronic algorithm to identify lung cancer prevalent patients in Colombia by using administrative claims databases, as well as to estimate prevalence rates by age, sex and geographic region. We performed a cross-sectional study based on national claim databases in Colombia (Base de datos de suficiencia de la Unidad de Pago por Capitación and Base de Datos Única de Afiliados) to identify lung cancer prevalent patients in 2017, 2018 and 2019. Several algorithms based on the presence or absence of oncological procedures (chemotherapy, radiotherapy and surgery) and a minimum number of months that each individual had lung cancer ICD-10 codes were developed. After testing 16 algorithms, those with the closest prevalence rates to those rates reported by aggregated official sources (Global Cancer Observatory and Cuenta de Alto Costo) were selected. We estimated prevalence rates by age, sex and geographic region. Two algorithms were selected: i) one algorithm that was defined as the presence of ICD-10 codes for 4 months or more (the sensitive algorithm); and ii) one algorithm that was defined by adding the presence of at least one oncological procedure (the specific algorithm). The estimated prevalence rates per 100,000 inhabitants ranged between 11.14 and 18.05 for both, the contributory and subsidized regimes over years 2017, 2018 and 2019. These rates in the contributory regime were higher in women (15.43, 15.61 and 17.03 per 100,000 for years 2017, 2018 and 2019), over 65-years-old (63.45, 56.92 and 61.79 per 100,000 for years 2017, 2018 and 2019) who lived in Central, Bogota and Pacific regions. Selected algorithms showed similar aggregated prevalence estimations to those rates reported by official sources and allowed us to estimate prevalence rates in specific aging, regional and gender groups for Colombia by using national claims databases. These findings could be useful to identify clinical and economical outcomes related to lung cancer patients by using national individual-level databases.

Type of funding sources: None.
Background
Despite improvement of heart failure (HF) prescription rates, doses prescribed in clinical practice are lower than those achieved in randomized clinical trials. Nurse-led up-titration strategy has been widely used in Europe with promising results. Nevertheless, there is no evidence of this approach in Latin America.
Methods
A prospective cohort study was conducted in 50 patients with reduced ejection fraction to evaluate efficacy and safety of nurse and general practioner(GP)-led up-titration protocol, based on problem solving from the European Society of Cardiology HF guidelines. Patients were admitted in our HF unit from January 2017 to December 2019. After discharge our clinical pathway provides 3 types of visits : Cardiologist visits, educational visits and titration visits with GP and registered nurse. Along intervention the registered nurse lead flexible diuretic titration and structured phone monitoring calls.
Results
Baseline characteristics are showed in Table 1. Mean age was 72.5 years, 50% of patients were women, 66% had ischemic cardiomiopathy, mean N-terminal pro-B-type natiuretic peptide was 3285pg/dl, and 58% of patients were NYHA class III. At 97 days with an average of 4 up-titration visits disease-modifying drugs titration was completed. At the beginning 98% of patients had Beta Blockers (BB) , 98% had Mineralocorticoid Receptor Antagonist (MRA), and all of them had Angiotensin Converting Enzyme Inhibitors, angiotensin receptor blockers or Angiotensin Receptor Neprilysin Inhibitor (ARNI). According to the guidelines Angiotensin Converting Enzyme Inhibitors and angiotensin receptor blockers were replaced by ARNI in symptomatic patients. At the end of titration, BB target dose was achieved for 44% of patients, intermediate dose for 46% and final low dose for only 10% of patients. Ivabradine was added for 22% of patients. MRA intermediate and high doses were achieved for 82,5% of patients. Target dose of ARNI was achieved for 62% of patients, intermediate dose for 22% and only 20% of patients remained in starting dose. On average ARNI target dose was completed at 56 days. According to our protocol three patients stopped MRA due to hyperkalemia and symptomatic hypotension was the main cause for stopping up-titration. There was a relationship between patient´s caregiver and higher doses of ARNI( p=0.624) and BB (p=0.421).
Conclusion
A nurse and GP directed up-titration protocol is an encouraging strategy in HF units to achieve the recommended doses of disease-modifying drugs according to the guidelines.

Abstract
Across the world, the COVID-19 pandemic has disproportionately affected economically disadvantaged groups. This differential impact has numerous possible explanations, each with significantly different policy implications. We examine, for the first time in a low- or middle-income country, which mechanisms best explain the disproportionate impact of the virus on the poor. Combining an epidemiological model with rich data from Bogotá, Colombia, we show that total infections and inequalities in infections are largely driven by inequalities in the ability to work remotely and in within-home secondary attack rates. Inequalities in isolation behavior are less important but non-negligible, while access to testing and contract-tracing plays practically no role because it is too slow to contain the virus. Interventions that mitigate transmission are often more effective when targeted on socioeconomically disadvantaged groups.

Abstract
OBJECTIVES Lung cancer imposes a significant economic burden on most countries. Nevertheless, there is scarce information about this burden on health systems in low- and middle-income countries. This study aims to estimate the economic burden of lung cancer on the Colombian health system, a middle-income country with universal health coverage in Latin America. METHODS We conducted a cost-of-illness study that included all direct costs generated by prevalent cases of lung cancer in Colombia during 2017. We used administrative databases containing patient-level information on consumption of healthcare services and reports on healthcare spending published by the Colombian Ministry of Health. To decrease the probability of misallocation of costs, we used propensity score matching to estimate the marginal costs of delivering healthcare services to patients with lung cancer. Additionally, ordinary least squares and variations in case definitions were used to assess the robustness of all estimates. RESULTS Total costs attributable to lung cancer in 2017 ranged from $50 039 588 to $74 468 111, with important differences across insurance regimes (from $4 629 938 for the subsidized regime to $55 342 357 for the contributory regime). Notably, 43% of all costs ($27 081 348) were caused by the consumption of services not included in the health benefit package. There were no significant differences between inpatient and outpatient costs. CONCLUSIONS Lung cancer imposes a significant economic burden on the Colombian health system. Although all affiliates are entitled to a unique health benefit package, there were important differences in costs across insurance regimes. Further research is needed to identify the main mechanisms underlying these differences.

Abstract
OBJECTIVE To validate the Charlson Comorbidity Index (CCI) for the Colombian population using administrative databases from the health insurance system. DESIGN Retrospective cohort study. SETTING Database reports of events related to services that insurers provided (Health Promoter Enterprises, EPS in Spanish) in the Colombian health system, which covered 22.19 million residents in 2016. PARTICIPANTS The study cohort comprised 3 849 849 patients aged 18 years and up admitted to the Colombian hospitals between 1 January and 31 December 2016. PRIMARY OUTCOME The study aimed to gauge the CCI's predictive value for mortality by comparing the calibration and discrimination of three different versions of the index, with mortality information obtained from death certificates, including date of death and diagnoses associated with cause of death. Follow-up was conducted for at least 1 year. RESULTS Altogether, 46 429 patients died within 1 year (1.21%). Discriminatory power in predicting 1-year mortality was calculated for three versions of the ICC. In the original CCI model, the area under the Receiver operating characteristic (ROC) curve was 0.906 (95% CI (0.906 to 0.907), p<0.001). In the version for Colombia, it was 0.908 (95% CI (0.908 to 0.909), p<0.001) and for the new model it was 0.909 (95% CI (0.908 to 0.910), p<0.001). CONCLUSIONS Adapting the CCI based on the 14 predictive variables of the new model resulted in an adequate predictive value for 1-year mortality in patients who were hospitalised for all causes. These findings support the use of the modified CCI in the Colombian population.

Abstract
Total knee arthroplasty (TKA) is one of the most frequent orthopaedic surgeries. The purpose of this study was to determine the 30-day postoperative mortality rate, total episode-of-care costs, and prognostic factors associated with these outcomes, for adult patients who underwent TKA in Colombia's contributory health care system. A retrospective cohort study of all adult patients enrolled in Colombia's contributory health system, who underwent TKA between January 1, 2012 and November 30, 2015 was performed. Thirty-day postoperative mortality rates, 30-day ICU admissions rates, 30-day hospital readmission rates, 1-year arthroplasty revision rates, and total episode-of-care costs were estimated. Multilevel, generalized linear models were generated, to determine the prognostic factors associated with outcomes presented. A total of 12,453 patients were included. The 30-day mortality rate was 0.13 per 100 surgeries and the ICU admissions rate at 30 days postoperative was 4.44 per 100 surgeries. The 30-day hospital readmission rate was 4.28 per 100 surgeries and the 1-year arthroplasty revision rate was 1.22 per 100 surgeries. The prognostic factors associated with mortality were age, Charlson Index, and type of insurer. The prognostic factors associated with hospital readmission were age category, Charlson Index, and geographic region; younger age and higher Charlson Index were found to be associated with a higher 1-year arthroplasty revision rate. The median of total episode-of-care costs was USD$ 6,190.07 (interquartile range: 2,299-7,282). The multivariate model found that age, the Charlson Index, the Atlantic region, and type of insurer were associated with the costs incurred by the health system. For patients undergoing TKA in Colombia, age, the Charlson Index, insurers, and geographic region are associated with mortality, ICU admissions, 30-day hospital readmissions, 1-year arthroplasty revisions, and total costs incurred by the health system.

Abstract
Rationale & Objective This study investigated the effects on patients’ outcomes of using medium cutoff (MCO) versus high-flux (HF) dialysis membranes. Study Design A retrospective, observational, multicenter, cohort study. Setting & Participants Patients aged greater than 18 years receiving hemodialysis at the Baxter Renal Care Services dialysis network in Colombia. The inception of the cohort occurred from September 1, 2017, to November 30, 2017, with follow-up to November 30, 2019. Exposure The patients were divided into 2 cohorts according to the dialyzer used at the inception: (1) MCO membrane or (2) HF membrane. Outcomes Primary outcomes were the hospitalization rate from any cause and hospitalization days per patient-year. Secondary outcomes were acute cardiovascular events and mortality rates from any cause and secondary to cardiovascular causes. Laboratory parameters were assessed throughout the 2-year follow-up period. Analytical Approach Descriptive statistics were used to report population characteristics. Inverse probability of treatment weighting was applied to each group before analysis. All categorical variables were compared using Pearson’s χ2 test, and continuous variables were analyzed with the t test. Baseline differences between groups with a value of >10% were considered clinically meaningful. Laboratory variables were measured at 5 consecutive time points. A between-patient effect was analyzed using a split-plot factorial analysis of variance. Results The analysis included 1,098 patients, of whom 564 (51.3%) were dialyzed with MCO membranes and 534 (48.7%) with HF membranes. Patients receiving hemodialysis with MCO membranes had a lower all-cause hospitalization incidence rate (IR) per patient-year (IR = 0.93; 95% CI, 0.82-1.03) than those receiving hemodialysis with HF membranes (IR = 1.13; 95% CI, 0.96-1.30), corresponding to a significant incident rate ratio (MCO/HF) of 0.82 (95% CI, 0.68-0.99; P = 0.04). The frequency of nonfatal cardiovascular events showed statistical significance, with a lower incidence in the MCO group (incident rate ratio = 0.66; 95% CI, 0.46-0.96; P = 0.03). No statistically significant differences in all-cause time until death were observed (P = 0.48). Albumin levels were similar between the 2 dialyzer cohorts. Limitations Despite the robust statistical analysis, there remains the possibility that unmeasured variables may still generate residual imbalance and, therefore, skew the results. Conclusions The incidences of hospitalization and cardiovascular events in patients receiving hemodialysis were lower when dialyzed with MCO membranes than HF membranes. A randomized controlled trial would be desirable to confirm these results. Trial Registration Clinical Trials.gov, ISRCTN12403265.

Abstract
Background We aim to determine the association between out and in-hospital factors with time, from the beginning of the symptoms to the surgery, in patients with acute appendicitis treated at Fundación Hospital Pediatrico La Misericordia (HOMI) in Colombia. Methods Eleven month prospective cohort study of pediatric patients at HOMI with acute appendicitis diagnosis taken to surgery. Data from the out-of-hospital phase was collected by surveying parents, and the data regarding the in-hospital phase was completed with medical records. We analyzed the association between the time from the beginning of the symptoms to the surgery, and out and in-hospital factors associated with this time using generalized linear models. Results Eight hundred three patients were included in the study. Total pre-surgical time was longer in perforated appendicitis (PA) group (2.65 days, standard deviation (SD) 1.88 vs. 2.04 days, SD 1.45) (p < 0.01). Factors associated with longer total and out-of-hospital presurgical times were age under 4 years old, lower socioeconomic status, father as a caregiver, self-medication, and underestimating disease severity. Conclusions Out-of-hospital timing determines the longer pre-surgical time in complicated appendicitis. Younger age and lower socioeconomic status affect time significantly. We suggest the implementation of strategies in order to lower prehospital time, rates, and costs of complicated appendicitis.

Abstract
INTRODUCTION This study is aimed at estimating the 30-day postoperative mortality rate and total costs of the medical episode, as well as determining prognostic factors associated with these outcomes for adult patients who have undergone total hip arthroplasty (THA) in Colombia's contributory health system. METHODS This was a retrospective cohort using administrative data and included adult patients enrolled in Colombia's contributory health system who underwent THA between the years 2011 and 2014. Outcomes were 30-day mortality ICU admissions, and the 1-year rate of fractures and revisions as well as the total cost of the medical episode incurred by the third-payer for 90 days following the procedure. Multilevel linear regression models were also generated to determine the prognostic factors associated with the outcomes presented. RESULTS The study included 17,289 patients, with an average age of 67 years. Outcome rates were calculated per 100 surgeries, resulting in 2.15 for mortality, 3.41 for ICU admissions, 2.42 for revision hip arthroplasty and 0.62 for periprosthetic fractures. This study found the age and Charlson Comorbidity Index were associated with mortality and complications, and that being female and performing the procedure in the capital city were protective factors. It also found that the median total cost of the medical episode was USD $ USD$2742.161 (p25-p75: 353.092-3291.747). The multivariate model found increasing trends in cost as age and CCI scores rose, and higher costs in the Atlantic region. CONCLUSIONS Colombia has higher rates of complications from THA than other countries but lower health system costs. For these patients, age, CCI and the geographic region are factors that are associated with mortality, complications, and health system costs.

Abstract
BACKGROUND The use of rosuvastatin plus colchicine and emtricitabine/tenofovir in hospitalized patients with SARS-CoV-2 disease (COVID-19) has not been assessed. The objective of this study was to assess the effectiveness and safety of rosuvastatin plus colchicine, emtricitabine/tenofovir, and their combined use in these patients. METHODS This was a randomized, controlled, open-label, multicentre, parallel, pragmatic study conducted in six referral hospitals in Bogotá, Colombia. The study enrolled hospitalized patients over 18 years of age with a confirmed diagnosis of COVID-19 complicated with pneumonia, not on chronic treatment with the study medications, and with no contraindications for their use. Patients were assigned 1:1:1:1. 1) emtricitabine with tenofovir disoproxil fumarate (FTC/TDF, 200/300 mg given orally for 10 days); 2) colchicine plus rosuvastatin (COLCH+ROSU, 0.5 mg and 40 mg given orally for 14 days); 3) emtricitabine with tenofovir disoproxil plus colchicine and rosuvastatin at the same doses and for the same period of time (FTC/TDF+COLCH+ROSU); or 4) the Colombian consensus standard of care, including a corticosteroid (SOC). The primary endpoint was 28-day all-cause mortality. A modified intention-to-treat analysis was used together with a usefulness analysis to determine which could be the best treatment. The trial was registered at ClinicalTrials.gov: NCT04359095. FINDINGS Out of 994 candidates considered between August 2020 and March 2021, 649 (65.3%) patients agreed to participate and were enrolled in this study; among them, 633 (97.5%) were included in the analysis. The mean age was 55.4 years (SD ± 12.8 years), and 428 (68%) were men; 28-day mortality was significantly lower in the FTC/TDF+COLCH+ROSUV group than in the SOC group, 10.7% (17/159) vs. 17.4% (28/161) (hazard ratio [HR] 0.53; 95% CI 0.29 to 0.96). Mortality in the FTC/TDF group was 13.8% (22/160, HR 0.68, 95% CI 0.39 to 1.20) and 14.4% in the COLCH+ROSU group (22/153) (HR 0.78, 95% CI 0.44 to 1.36). A lower need for invasive mechanical ventilation was observed in the FTC/TDF+COLCH+ROSUV group than in the SOC group (risk difference [RD] - 0.08, 95% CI 0.11 to 0.04). Three patients presented severe adverse events, one severe diarrhoea in the COLCH+ROSU and one in the FTC/TDF+COLCH+ROSU group and one general exanthema in the FTC/TDF group. INTERPRETATION The combined use of FTC/TDF+COLCH+ROSU reduces the risk of 28-day mortality and the need for invasive mechanical ventilation in hospitalized patients with pulmonary compromise from COVID-19. More randomized controlled trials are needed to compare the effectiveness and cost of treatment with this combination versus other drugs that have been shown to reduce mortality from SARS-CoV-2 infection and its usefulness in patients with chronic statin use.

Abstract
Internal armed conflicts have become more common and more physically destructive since the mid-20th century, with devastating consequences for health and development in low- and middle-income countries. This paper investigates the causal impacts of the long-term internal conflict on child health in Colombia, following an identification strategy based on the temporal and geographic variation of conflict intensity. We estimate the effect of different levels of conflict intensity on height-for-age (HAZ), weight-for-age (WAZ), and weight-for-height z-scores among children under five years old, and explore the underlying potential mechanisms, through maternal health behavior and health care utilization. We find a harmful effect of exposure to conflict violence in utero and in early childhood for HAZ and WAZ, in the full sample and even more strongly in the rural sample, yet these estimates are smaller than those found for shorter term conflicts. The underlying pathways appear to operate around the time of the pregnancy and birth (in the form of maternal alcohol use, use of antenatal care and skilled birth attendance), rather than during the post-birth period (via breastfeeding or vaccination), and the impacts accumulate over the childhood. The most adverse impacts of conflict violence on child health and utilization of maternal healthcare were observed in municipalities which suffered from intermittent presence of armed groups.

Abstract
INTRODUCTION Comparisons of survival between dialysis modalities is of great importance to patients with kidney failure, their families, and healthcare systems. OBJECTIVE This study's objective was to compare mortality of patients on chronic hemodialysis (HD) or peritoneal dialysis (PD) and identify variables associated with mortality. METHODS This retrospective cohort study included adult incident patients with kidney failure treated with HD or PD by the Baxter Renal Care Services network in Colombia. The study was conducted between January 1, 2008, and December 31, 2013 (recruitment period), with follow-up until December 31, 2018. The outcome was the cumulative mortality rate at 1, 2, 3, 4, and 5 years. Propensity score matching (PSM) and the Gompertz parametric survival model were used to compare mortality in HD versus PD. RESULTS The analysis included 12,499 patients, of whom 57.4% were on PD at inception. The overall mortality rate was 14.0 events per 100 patient-years (95% confidence interval [CI], 13.61-14.42). Using an intention-to-treat approach, crude mortality rates were significantly lower in patients receiving HD (HD: 12.3 deaths per 100 patient-years [95% CI, 11.7-12.8] vs. PD: 15.5 [14.9-16.1], p < 0.01). Using a Gompertz parametric survival model, dialysis modality was not significantly associated with mortality (hazard ratio HD vs. PD 1.0, 95% CI, 0.9-1.1). After PSM, the mortality cumulative incidence functions between HD and PD were not statistically significantly different (p = 0.88). CONCLUSIONS The present study in a large cohort of incident dialysis patients with at least 5 years follow-up and using PSM methods showed no differences in cumulative mortality between HD and PD patients. This evidence from a middle-income country may facilitate the process of dialysis modality selection globally.

Abstract
Given the lack of a gold standard, the clinical usefulness of Comprehensive Genomic Profiling (CGP) has not been established. This systematic review aimed to evaluate evidence about the clinical benefit of CGP for patients with Non-small cell lung carcinoma (NSCLC). All controlled studies that evaluated the ability of CGP to detect actionable targets (ATs) reported increases in the number of samples with ATs. The frequency of ATs detected in uncontrolled case series ranged from 0.7 % for RET mutations to 45 % for EGFR mutations. The studies that evaluated therapies targeted to EGFR, ALK, ROS-1, MET, and RET mutations documented significant improvement in clinical outcomes. This review suggests that CGP tests may be clinically helpful for treating patients with NSCLC. Although current evidence is associated with a high risk of bias, the significant impact of NSCLC on individuals and society may justify the routine use of CGP testing for this disease.

Abstract
Latin America has been severely affected by the COVID-19 pandemic but estimations of rates of infections are very limited and lack the level of detail required to guide policy decisions. We implemented a COVID-19 sentinel surveillance study with 59,770 RT-PCR tests on mostly asymptomatic individuals and combine this data with administrative records on all detected cases to capture the spread and dynamics of the COVID-19 pandemic in Bogota from June 2020 to early March 2021. We describe various features of the pandemic that appear to be specific to a middle income countries. We find that, by March 2021, slightly more than half of the population in Bogota has been infected, despite only a small fraction of this population being detected. The initial buildup of immunity contributed to the containment of the pandemic in the first and second waves. We also show that the share of the population infected by March 2021 varies widely by occupation, socio-economic stratum, and location. This, in turn, has affected the dynamics of the spread with different groups being infected in the two waves.

Abstract
OBJECTIVE To examine socioeconomic inequalities in birth outcomes among infants born between 2008 and 2018 and assessed trends in inequalities during that period in Colombia, a middle-income country with high levels of inequality emerging from a long internal armed conflict. METHODS Using birth certificate data in Colombia, we analysed the outcomes of low birth weight, an Apgar score <7 at 5 minutes after birth and the number of prenatal visits among full-term pregnancies. Maternal education and health insurance schemes were used as socioeconomic position (SEP) indicators. Inequalities were estimated using the prevalence/mean of the outcomes across categories of the SEP indicators and calculating the relative and slope indices of inequality (RII and SII, respectively). RESULTS Among the 5,433,265 full-term singleton births analysed, there was a slight improvement in the outcomes analysed over the study period (lower low-birth-weight and Apgar<7 prevalence rates and higher number of prenatal visits). We observed a general pattern of social gradients and significant relative (RII) and absolute (SII) inequalities for all outcomes across both SEP indicators. RII and SII estimates with their corresponding CIs revealed a general picture of no significant changes in inequalities over time, with some particular, time-dependent exceptions. When comparing the initial and final years of our study period, inequalities in low birth weight related to maternal education increased while those in Apgar score <7 decreased. Relative inequalities across health insurance schemes increased for the two birth outcomes but decreased for the number of prenatal visits. CONCLUSION The lack of a consistent improvement in the magnitude of inequalities in birth outcomes over an 11-year period is a worrying issue because it could aggravate the cycle of inequality, given the influence of birth outcomes on health, social and economic outcomes throughout the life course. The findings of our analysis emphasize the importance of policies aimed at providing access to quality education and providing a health care system with universal coverage and high levels of integration.

Abstract
BACKGROUND The relationship between exposure to conflict violence during pregnancy and the risks of miscarriage, stillbirth, and perinatal mortality has not been studied empirically using rigorous methods and appropriate data. We investigated the association between reduced exposure to conflict violence during pregnancy and the risks of adverse pregnancy outcomes in Colombia. METHODS AND FINDINGS We adopted a regression discontinuity (RD) design using the July 20, 2015 cease-fire declared during the Colombian peace process as an exogenous discontinuous change in exposure to conflict events during pregnancy, comparing women with conception dates before and after the cease-fire date. We constructed the cohorts of all pregnant women in Colombia for each day between January 1, 2013 and December 31, 2017 using birth and death certificates. A total of 3,254,696 women were followed until the end of pregnancy. We measured conflict exposure as the total number of conflict events that occurred in the municipality where a pregnant woman lived during her pregnancy. We first assessed whether the cease-fire did induce a discontinuous fall in conflict exposure for women with conception dates after the cease-fire to then estimate the association of this reduced exposure with the risks of miscarriage, stillbirth, and perinatal mortality. We found that the July 20, 2015 cease-fire was associated with a reduction of the average number of conflict events (from 2.64 to 2.40) to which women were exposed during pregnancy in their municipalities of residence (mean differences -0.24; 95% confidence interval [CI] -0.35 to -0.13; p < 0.001). This association was greater in municipalities where Fuerzas Armadas Revolucionarias de Colombia (FARC) had a greater presence historically. The reduction in average exposure to conflict violence was, in turn, associated with a decrease of 9.53 stillbirths per 1,000 pregnancies (95% CI -16.13 to -2.93; p = 0.005) for municipalities with total number of FARC-related violent events above the 90th percentile of the distribution of FARC-related conflict events and a decrease of 7.57 stillbirths per 1,000 pregnancies (95% CI -13.14 to -2.00; p = 0.01) for municipalities with total number of FARC-related violent events above the 75th percentile of FARC-related events. For perinatal mortality, we found associated reductions of 10.69 (95% CI -18.32 to -3.05; p = 0.01) and 6.86 (95% CI -13.24 to -0.48; p = 0.04) deaths per 1,000 pregnancies for the 2 types of municipalities, respectively. We found no association with miscarriages. Formal tests support the validity of the key RD assumptions in our data, while a battery of sensitivity analyses and falsification tests confirm the robustness of our empirical results. The main limitations of the study are the retrospective nature of the information sources and the potential for conflict exposure misclassification. CONCLUSIONS Our study offers evidence that reduced exposure to conflict violence during pregnancy is associated with important (previously unmeasured) benefits in terms of reducing the risk of stillbirth and perinatal deaths. The findings are consistent with such beneficial associations manifesting themselves mainly through reduced violence exposure during the early stages of pregnancy. Beyond the relevance of this evidence for other countries beset by chronic armed conflicts, our results suggest that the fledgling Colombian peace process may be already contributing to better population health.

Abstract
e18784 Background: There is need for high quality data about the economic burden of disease in low- and middle-income countries. We aimed to determine the annual incremental cost of health care services utilized by lung cancer patients in the Colombian health system. Methods: We conducted a national cohort study of prevalent patients with lung cancer in Jan-2017 and followed-up until Dec-2017. We used two electronic algorithms to identify all lung cancer prevalent patients in the Contributory regime, using national health claims databases ( Base de datos de suficiencia de la Unidad de Pago por Capitación and Base de Datos Única de Afiliados), based on identification of ICD-10 codes for 4 months or more during the previous 3 years (sensitive algorithm) and adding the presence of at least one oncological procedure (specific algorithm). We identified all health services cost from the health system perspective (2017 USD). We performed a propensity score analysis to estimate the annual incremental cost of care of patients with lung cancer compared to those without the disease. Standardized differences lower than 0.1 were used to measure the balance of baseline variables. We used generalized linear models as a sensitivity analysis. Results: We identified 4,827 and 3,238 lung cancer prevalent patient using the sensitive and specific algorithm, respectively. Each cohort was matched 1:1 with a no-exposed cohort of 14,968,202 individuals without a diagnosis of lung cancer using a caliper of 0.0001. Matched samples showed good balance on baseline characteristics. Annual incremental cost for patients diagnosed with lung cancer in Colombia ranged between USD $ 3,146.92 and USD $ 4,156.23. We also estimated incremental cost for outpatient and inpatient healthcare services as shown in table. Conclusions: In 2017, each patient with lung cancer represented an incremental cost to the Colombian health system between 49.35% and 65.19% of GDP per capita. This information is paramount to understand lung cancer spending in Colombia and for other low- and middle-income countries. [Table: see text]

Abstract
e18808 Background: Fragmentation in healthcare leads to adverse outcomes in cancer patients. Currently there is no fragmentation measurement that has been acknowledged to reliably assess healthcare fragmentation across different health systems. We aimed to measure cancer healthcare fragmentation through administrative databases in Colombia and to calculate its effect on breast, stomach and colorectal cancer mortality. Methods: We conducted a cohort study based on health administrative databases from 2013 to 2017. We combined data from two Colombian national health databases (Capitation Payment Unit database and Vital Statistics from DANE). We developed an algorithm based on ICD-10 codes and oncological procedures to select incident cases of breast, stomach and colorectal cancer. To measure healthcare fragmentation, we identified the number of providers between the dates of the first and last registered services. For patients who died during observation we adjusted the number of providers for survival time in days, otherwise survival time was set to 31 december, 2017. We categorized fragmentation in quartiles and evaluated its effect on mortality rate by Kaplan Meier estimates. Results: We identified three cohorts of patients based on primary tumor site. Age distribution was similar in stomach and colorectal cancer. Fragmentation measured as a continuous variable has a non-parametric distribution in all cohorts. The median of follow-up time ranged between 2.4 to 4.4 years. All-cause mortality rates were highest in stomach cancer, lowest in breast cancer. When measured as quartiles, fragmentation has a consistent dose-response effect increasing all-cause mortality rates. Conclusions: Healthcare fragmentation can be measured through algorithms applied to administrative databases in Colombia. Fragmentation is a predictor for all-cause mortality across different oncologic populations. This measurement based on real-world national administrative data could be used as an indicator of high-quality oncological healthcare for the Colombian healthcare system.[Table: see text]

Abstract
e18810 Background: Breast, stomach and colorectal cancers have high incidence in Colombia. Official cancer incidence registries depend upon sentinel site reports as there is no nationwide surveillance system. We aimed to identify administrative database algorithms for breast, stomach and colorectal cancer case selection and to compare their cancer incidence estimates to official registries. Methods: We conducted a systematic review to identify algorithms with high positive predictive values (VPP) for breast, stomach and colorectal cancer case identification in administrative databases. For each cancer we selected two algorithms: a sensitive algorithm, based on cancer-specific ICD-10 codes, and a specific algorithm, combining cancer-specific ICD-10 codes with at least one code for oncological procedures. We varied the number of months a cancer-specific ICD-10 code was registered within each algorithm to test for algorithm stability. We conducted a cohort study to estimate incident cancer cases for 2013 in four cancer sentinel cities in Colombia and one cancer reference center using both algorithms. We defined incident cases as cases lacking a cancer-specific ICD-10 code in the preceding two years and adjusted incident cases for type of regimen affiliation. Algorithms with results closest to official sources were selected as best performing algorithms. We used the contributive regimen Capitation Payment Unit administrative database of Colombia for 2011-2014 as source of information. Results: Breast cancer case-identification algorithms have a higher VPP reported in literature (83-100%) compared to colorectal (41.7-94%) and stomach cancer (35-59.7%) algorithms. The closest breast cancer incidence estimates to the official registries Infocancer and National Cancer Institute were yielded by the specific algorithm with ICD-10 codes persisting for four months (n= 672 vs 649 and 397 vs 212, respectively). The closest colorectal cancer cancer incidence estimates to official registries were yielded by the specific algorithm with ICD-10 codes persisting for three months (n= 219 vs 230 and 168 vs 139, respectively). The closest stomach cancer incidence estimates to official registries were yielded by the specific algorithm with ICD-10 codes persisting for one month (n= 122 vs 146 and 99 vs 153, respectively). Sensitive algorithms were less stable than specific algorithms across all three cancer types. Conclusions: Breast, stomach and colorectal incident cancer cases can be identified through administrative databases. VPP vary among types of algorithms and cancers. Specific algorithms provide better breast and colorectal incident cancer case-identification in Colombian administrative databases, compared to stomach cancer algorithms. This is a potential approach for estimating nationwide cancer incidence in Colombia.

Abstract
e18764 Background: Reliable, timely and detailed information of lung cancer mortality and costs from low- and middle-income countries is essential to policy design. We aimed to develop an electronic algorithm to identify lung cancer prevalent patient in Colombia using official databases and to estimate prevalence rates by age, sex, and geographic region. Methods: We performed a cross sectional study based on national claim databases in Colombia ( Base de datos de suficiencia de la Unidad de Pago por Capitación and Base de Datos Única de Afiliados) to identify lung cancer prevalent patients in 2017. Several algorithms based on the presence or absence of oncological procedures (Chemotherapy, radiotherapy and surgery), and a minimum number of months that each individual had lung cancer ICD-10 codes in the previous 3 years, were developed. After testing 16 algorithms, those with the closest prevalence rates to the ones reported by aggregated official sources (GLOBOCAN, National Cancer Institute and Cuenta de Alto Costo) were selected . We estimated prevalence rates by age, sex, and geographic region. Results: Two algorithm s were selected: i) it was defined as the presence of ICD-10 codes for 4 months or more (sensitive algorithm); and ii) adding the presence of at least one oncological procedure (specific algorithm). Estimated prevalence rates per 100,000 population were 15.3 and 9.7 for the sensitive and specific algorithms, respectively. These rates were higher in men (9.9), over 65 years old (37.1), who lived in Central and Bogota regions (14.7 and 10.9, respectively) (Table). Conclusions: Selected algorithms showed similar prevalence estimations to those reported by official sources and allowed us to estimate prevalence rates in specific aging, regional and gender groups for Colombia using national claims databases. These findings could be useful to identify clinical and economical outcomes related to lung cancer patients using national individual-level databases. [Table: see text]

Abstract
Introducción. Los microcarcinomas papilares de tiroides son tumores de hasta 10 mm en su diámetro mayor. Su tratamiento es sujeto de debate y se propone, desde seguimiento clínico, hasta intervención quirúrgica temprana. Este estudio buscó identificar factores de riesgo relacionados con compromiso ganglionar, que permitan una mejor selección de los pacientes en nuestro medio, en quienes se propone manejo quirúrgico inmediato o vigilancia activa, en consonancia con la clasificación del riesgo de progresión. Métodos. Estudio de cohorte analítica ambispectiva que incluyó pacientes con microcarcinoma papilar de tiroides llevados a tiroidectomía más vaciamiento central. Se caracterizó la población y se realizó un análisis de regresión logística multivariado para definir factores preoperatorios asociados al compromiso ganglionar. Adicionalmente, se evaluó de manera retrospectiva la eventual asignación a grupos de riesgo de progresión, según los criterios de Miyauchi, y su comportamiento respecto al estado nodal. Resultados. Se incluyeron 286 pacientes. El 48,9 % presentó compromiso ganglionar, y de estos, el 33,5 % presentó compromiso ganglionar significativo, que modificó su clasificación de riesgo de recaída. De estos últimos, el 59,5 % hubiesen sido manejados con vigilancia activa, según los criterios propuestos por Miyauchi. Se identificó que la edad menor de 55 años, los ganglios sospechosos en la ecografía y los nódulos mayores de 5 mm, se relacionan con compromiso ganglionar significativo. Discusión. El manejo quirúrgico inmediato parece ser una opción adecuada para pacientes con sospecha de compromiso ganglionar en ecografía preoperatoria, pacientes menores de 55 años y nódulos mayores de 5 mm. Es posible que los actuales criterios para definir vigilancia activa no seleccionen adecuadamente a los pacientes en nuestro medio.

Abstract
INTRODUCTIOn: Studies on Chagas disease-related mortality assist in decision-making in health policies. We analyzed the epidemiological characteristics, temporal trends, and regional differences in Chagas disease-related mortality in Colombia from 1979 to 2018. METHODS: A time-series study was conducted using death records and population data from the National Administrative Department of Statistics, using categorizations from the International Classification of Disease (ICD)-9 and ICD-10 systems. All deaths with Chagas disease as an underlying or associated cause of death were included. Crude and age-sex standardized mortality rates per 100,000 inhabitants and the annual percent change (APC) were calculated. RESULTS: Of the 7,287,461 deaths recorded in Colombia during 1979-2018, 3,276 (0.04%) deaths were related to Chagas disease-2,827 (86.3%) as an underlying cause and 449 (13.7%) as an associated cause. The average annual age-sex standardized mortality rate was 0.211 (95% confidence interval [CI]: 0.170-0.252) deaths/100,000 inhabitants, with a significant upward trend (APC = 6.60%; 95% CI: 5.9-7.3). The highest Chagas disease-related death rates were in males (0.284 deaths/100,000 inhabitants), those ≥65 years old (1.296 deaths/100,000 inhabitants), and residents of the Orinoco region (1.809 deaths/100,000 inhabitants). There was a significant increase in mortality in the Orinoco (APC = 8.28%; 95% CI: 6.4-10.2), Caribbean (APC = 5.06%; 95% CI: 3.6-6.5), and Andean (APC = 4.63%; 95% CI: 3.9-5.3) regions. CONCLUSIONS: Chagas disease remains a major public health issue in Colombia with high mortality rates in older age groups, a wide geographic distribution, regional differences, and the potential to increase.

Abstract
Chagas disease represents an important cause of heart failure (HF) and affects health-related quality of life (HRQoL). The study aimed to evaluate and compare the HRQoL of patients with chagasic HF and matched non-Chagas controls to identify factors associated with HRQoL. A cross-sectional study with pair-matched controls was conducted in Colombia. From October 2018 to December 2019, a total of 84 HF patients were screened for study subjects. Four were excluded, resulting in 80 patients for the analysis, among whom 40 patients with Chagas were enrolled as cases and 40 gender- and age-matched non-Chagas patients as controls. The Kansas City Cardiomyopathy Questionnaire (KCCQ) and the Minnesota Living with Heart Failure Questionnaire (MLWHFQ) were used to measure HRQoL. Demographic, clinical, and laboratory data were obtained from each subject. Health-related quality of life scores were significantly worse among the Chagas group than among the non-Chagas group in the KCCQ domains of physical functioning and symptoms and in the MLWHFQ scale. In the multivariate analysis, the variables associated with lower HRQoL scores were living alone, obesity, having less than 12 years of education, and an increase in left ventricular diameters in the systole and diastole. Health-related quality of life in patients with chronic HF is impaired across all domains. Chagas patients showed worse HRQoL scores than non-Chagas patients. Six variables, some potentially modifiable, were independently associated with worse HRQoL.

Abstract
BACKGROUND Remote patient monitoring (RPM) programs in automated peritoneal dialysis (APD) allow clinical teams to be aware of many aspects and events of the therapy that occur in the home. The present study evaluated the association between RPM use and APD technique failure. METHODS A retrospective, multicentre, observational cohort study of 558 prevalent adult APD patients included between 1 October 2016 and 30 June 2017 with follow-up until 30 June 2018 at Renal Therapy Services network in Colombia. Patients were divided into two cohorts based on the RPM use: APD-RPM (n = 148) and APD-without RPM (n = 410). Sociodemographic and clinical characteristics of all patients were summarized descriptively. A propensity score was used to create a pseudo-population in which the baseline covariates were well balanced. The association of RPM with technique failure was estimated adjusting for the competing events death and kidney transplant. RESULTS Five hundred fifty-eight patients were analyzed. 26.5% had APD-RPM. In the matched sample comprising 148 APD-RPM and 148 APD-without RPM patients, we observed a lower technique failure rate of 0.08 [0.05-0.15] episodes per patient-year in APD-RPM versus 0.18 [0.12-0.26] in APD-without RPM cohort; incidence rate ratio = 0.45 95% confidence interval: [0.22-0.91], p-value = 0.03. CONCLUSIONS The use of an RPM program in APD patients may be associated with a lower technique failure rate. More extensive and interventional studies are needed to confirm its potential benefits and to measure other patient-centered outcomes.

Abstract
Objectives Thyroid cancer is the most common endocrine neoplasm in childhood. There are few studies characterizing pediatric population in Colombia. We intend to detail the clinical, histological characteristics, BRAFV600E mutational status and NIS (sodium-iodine symporter) expression of children with papillary thyroid carcinoma (PTC) managed at Hospital de La Misericordia. Methods Medical records of the Department of Pediatric Surgery and Pathology from 2009 to 2018 were scrutinized in search of cases of differentiated thyroid carcinoma. A descriptive analysis was made. Paraffin embedded tumoral tissue was recovered to assess BRAF V600E mutational status by PCR and NIS expression by immunohistochemistry. Results Sixteen patients were selected, 81.2% were girls. Average age of presentation was 11.8 years. Only one patient had previous radiation exposure. Most frequent symptom was cervical adenopathy with a mean time of 29.2 weeks before diagnosis. 93.7% underwent total thyroidectomy and lymphadenectomy. 62.5% were PTC combining both classic and follicular pattern. 6.25% cases had BRAFV600E mutation and 25% showed NIS focal reactivity. Conclusions We found greater female predominance, lower percentage of risk factors described and a high percentage of patients requiring aggressive surgical treatment. We consider important to contemplate thyroid cancer as a differential diagnosis of cervical lymph node enlargement in children. Diagnosis can be challenging in benign and indeterminate categories of the FNA cytology and biomolecular profiles such as BRAF and NIS could be determinant in guiding treatment. More studies with larger sample size, complete genetic analysis, evaluation to iodine response and long term follow up are required.

Abstract
Introduction: The use of matching techniques in observational studies has been increasing and is not always used appropriately. Clinical experiments are not always feasible in critical patients with renal outcomes, and observational studies are an important alternative.
Objective: Through a scoping review, determine the available evidence on the use of matching methods in studies involving critically ill patients and assessing renal outcomes.
Methods: Medline, Embase, and Cochrane databases were used to identify articles published between 1992 and 2020 up to week 10, which studied different exposures in the critically ill patient with renal outcomes and used propensity matching methods.
Results: Most publications are cohort studies 94 (94. 9 %), five studies (5. 1 %) were cross-sectional. The main pharmacological intervention was the use of antibiotics in seven studies (7. 1%) and the main risk factor studied was renal injury prior to ICU admission in 10 studies (10. 1%). The balance between the baseline characteristics assessed by standardized means, in only 28 studies (28. 2%). Most studies 95 (96 %) used logistic regression to calculate the propensity index.
Conclusion: Major inconsistencies were observed in the use of methods and in the reporting of findings. A summary is made of the aspects to be considered in the use of the methods and reporting of the findings with the matching by propensity index.

Abstract
Background Between 30 and 70% of patients admitted to the intensive care unit (ICU) have acute kidney injury (AKI), and 10% of these patients will require renal replacement therapy (RRT). A significant number of studies have compared the mortality of patients who require RRT versus those who do not require it, finding an increase in mortality rates in the short and medium term; however, few studies have evaluated the long-term survival in a mixture of patients admitted to the ICU. Objective To evaluate the impact of RRT on 5-year survival in patients with AKI admitted to the ICU. Methods Using administrative databases of insurers of the Colombian health system, a cohort of patients admitted to the ICU between 1 January 2012 and 31 December 2013 was followed until 31 December 2018. ICD-10 diagnoses, procedure codes, and prescribed medications were used to establish the frequencies of the comorbidities included in the Charlson index. Patients were followed for at least 5 years to evaluate survival and establish the adjusted risks by propensity score matching. Results Of the 150,230 patients admitted to the ICU, 4366 (2.9%) required RRT in the ICU. Mortality rates for patients with RRT vs no RRT evaluated at ICU discharge, 1 year, and 5 years were 35%, 57.4%, and 67.9% vs 7.4%, 17.6%, and 30.1%, respectively. After propensity score matching, the hazard ratio was calculated for patients who received RRT and those who did not (HR, 2.46; 95% CI 2.37 to 2.56; p < 0.001), with a lower difference in years of survival for patients with RRT (mean effect in the treated) of - 1.86 (95% CI - 2.01 to to1.65; p < 0.001). Conclusions The impact of acute renal failure with the consequent need for RRT in patients admitted to the ICU is reflected in a decrease of approximately one quarter in 5-year survival, regardless of the different comorbidities.

Abstract
Patients undergoing arthroplasty are exposed to different interventions that can lead to renal dysfunction. There is abundant evidence of the incidence and factors associated with acute kidney injury (AKI); however, the incidence and the factors associated with chronic kidney disease (CKD) are not clear. The objective of this study is to determine the incidence and associated factors in arthroplasty patients. A systematic review of the literature was carried out following the recommendations of PRISMA and the Cochrane Collaboration (PROSPERO Protocol CRD42018075929). The search was carried out in Medline, Embase, Cochrane and LILACS. No language or date limits were set. Observational studies were included: cases and controls, and cohorts. The revision of titles and abstracts and the reading of the full texts was performed in a paired manner. The quality of the evidence was evaluated with the Newcastle-Ottawa tool. The initial search found 1279 titles and abstracts. We excluded 115 duplicates, and 1153 in the reading of titles and abstracts. Three articles met the inclusion criteria and were of acceptable quality. The incidence of severe CKD after hip or knee arthroplasty was 1.2% at 1 year up to 6.5% at 9 years. The evidence of the incidence and risk factors associated with CKD in patients undergoing arthroplasty is very scarce and heterogeneous. Further primary studies are required in order to have more valid and trustable results.

Abstract
INTRODUCTION While there is evidence of obstetric and neonatal outcomes from non-obstetric surgery during pregnancy, surgery during the third trimester of gestation has not been evaluated as a prognostic factor for those outcomes. The objective of this study was to determine whether appendectomies during the third trimester are associated with adverse neonatal outcomes, in comparison with appendectomies during the first two trimesters, based on national administrative data in Colombia. METHODS A retrospective cohort study was performed using administrative health records. It included all women who had live births and who underwent an appendectomy during any stage of pregnancy, between the years 2011 and 2016, and who belonged to Colombia's contributory health system. The main outcome was preterm birth. Birth weight and 1-min and 5-min Apgar scores were also measured, as well as outcomes used to identify neonatal near-miss cases. Propensity score matching was used in order to balance baseline characteristics (age, weeks of gestation, obstetric comorbidity index, and region and year the procedure was performed). Relative risks were estimated with Poisson regressions. RESULTS This study included a total of 2507 women in Colombia's contributory health system who underwent an appendectomy during pregnancy. Appendectomy was performed on 885 women (35.30%) in their first trimester, 1205 women (48.07%) in their second trimester, and 417 women (16.63%) in their third trimester. For the entire population, the preterm birth rate was 11.85 per 100 appendectomies. With the matched sample, this study found that women in their third trimester had a 1.65 greater risk of preterm birth [95% CI, 1.118-2.423], a 3.43 greater risk of birth at gestational ages < 33 weeks [95% CI, 1.363 to 8.625], 2.083 greater risk of weight under 1750 g [95% CI, 1.056-4.109], and a mean difference of - 0.247 [95% CI, - .382 to - .112] in the 1-min Apgar score and - .168a [95% CI, - .276 to - .060] in the 5-min Apgar. No differences were found in birth weight or Apgar scores < 7. CONCLUSIONS In Colombia's contributory health system, women who undergo appendectomies in their third trimester have a greater risk of preterm birth, birth weight under 1750 g, birth at gestational ages less than 33 weeks, and decreased 1-min and 5-min Apgar scores.

Abstract
Introduction: Minimally invasive surgery (MIS) in pediatric surgery is now the standard of care for various surgical conditions. We have seen an increase in MIS with some of the procedures requiring intraoperative conversion to open surgery. Materials and Methods: This is a single-institution retrospective study of patients who underwent MIS between 2009 and 2017 requiring conversion to open surgery. Preoperative characteristics, cause of conversion, and postoperative factors were recorded. Results: A total of 154 patients had converted to MIS, 89.6% underwent laparoscopic procedures. Mean age was 8.5 years, 53.9% were male. Primary cause leading to surgery was not oncologic (89.6%), dirty contaminated wound was found in 49.35%, inflammatory response markers were altered, and 38.9% of our patients were American Society of Anesthesiologists physical status classification 3. Principal causes of conversion were failure in progression (53.25%) and loss of anatomic reference (24.5%). A total of 44.16% of the patients required postoperative pediatric intensive care unit admission, 29.2% required reintervention, and mortality rate was 0.65%. We detailed data regarding thoracoscopic, appendectomy, and laparoscopic procedures. Conclusion: Conversion to MIS is a decision the surgeon must make in different scenarios. This study allowed us to characterize our population regarding converted MIS procedures. Male gender, age group, altered inflammatory markers, not oncologic pathology, and dirty wound were frequently found, but we cannot establish any of them as risk factors. Main cause for conversion to open surgery was failure in the progression of the procedure in our study according to reported literature. We intend to develop further studies to determine risk factors.

Abstract
Background:Automated peritoneal dialysis (APD) is a growing PD modality but as with other home dialysis methods, the lack of monitoring of patients' adherence to prescriptions is a limitation with potential negative impact on clinical outcome parameters. Remote patient monitoring (RPM) allowing the clinical team to have access to dialysis data and adjust the treatment may overcome this limitation. The present study sought to determine clinical outcomes associated with RPM use in incident patients on APD therapy.Methods:A retrospective cohort study included 360 patients with a mean age of 57 years (diabetes 42.5%) initiating APD between 1 October 2016 and 30 June 2017 in 28 Baxter Renal Care Services (BRCS) units in Colombia. An RPM program was used in 65 (18%) of the patients (APD-RPM cohort), and 295 (82%) were treated with APD without RPM. Hospitalizations and hospital days were recorded over 1 year. Propensity score matching 1:1, yielding 63 individuals in each group, was used to evaluate the association of RPM exposure with numbers of hospitalizations and hospital days.Results:After propensity score matching, APD therapy with RPM (n = 63) compared with APD-without RPM (n = 63) was associated with significant reductions in hospitalization rate (0.36 fewer hospitalizations per patient-year; incidence rate ratio [IRR] of 0.61 [95% confidence interval (CI) 0.39 - 0.95]; p = 0.029) and hospitalization days (6.57 fewer days per patient-year; IRR 0.46 [95% CI 0.23 - 0.92]; p = 0.028).Conclusions:The use of RPM in APD patients is associated with lower hospitalization rates and fewer hospitalization days; RPM could constitute a tool for improvement of APD therapy.

Abstract
BACKGROUND Although many studies have compared outcomes of laparoscopic appendectomy (LA) and open appendectomy (OA), some clinical and economic outcomes continue to be controversial, particularly in low-medium-income countries. We aimed at determining clinical and economic outcomes associated with LA versus OA in adult patients in Colombia. METHODS Retrospective, cohort study based on administrative healthcare records included all patients who underwent LA or OA in Colombia's contributory regime between July 1, 2013, and September 30, 2015. Outcomes were 30-day mortality rates, ICU admissions rates, length of stay (LOS), and hospital costs provided until discharge. Propensity score matching techniques were used to balance the baseline characteristics of patients (age, sex, comorbidities based on the Charlson index, insurer, and geographic location) and to estimate the average treatment effect (ATE) of LA as compared to OA over outcomes. RESULTS A total of 65,625 subjects were included, 92.9% underwent OA and 7.1% LA. For the entire population, 30-day mortality was 0.74 per 100 appendectomies (95% CI 0.67-0.81), the mean and median LOS were 3.83 days and 1 day, respectively, and the ICU admissions rate during the first 30 days was 7.92% (95% CI 7.71-8.12). The ATE shows an absolute difference in the mortality rate after 30 days of -0.35 per 100 appendectomies (p = 0.023), in favor of LA. No effects on ICU admissions or LOS were identified. LA was found to increase costs by 514.13 USD on average, with total costs of 772.78 USD for OA and 1286.91 USD for LA (p < 0.001). CONCLUSIONS In Colombia's contributory regime, LA is associated with lower 30-day mortality rate and higher hospital costs as compared to OA. No differences are found in ICU admissions or LOS.

Abstract
Background Despite the adoption of campaigns to interrupt the main vector and to detect Trypanosoma cruzi in blood banks, millions of people are still chronically infected; however, the prevalence data are limited, and the epidemiology of Chagas disease has not been systematically evaluated. This study aimed to estimate the prevalence of Chagas disease in Colombia. Methods A systematic literature review and meta-analysis was conducted to select all observational studies reporting the prevalence of Chagas disease in Colombia, based on serological diagnosis in participants of any age and published between January 2007 and November 2017. Pooled estimates and 95% confidence intervals (95% CIs) were calculated using random-effects models. In addition, the I2 statistic was calculated. Results The literature search yielded a total of 1,510 studies; sixteen articles with relevant prevalence data were included in the systematic review. Of these, only 12 articles were included for entry in the meta-analysis. The pooled prevalence of Chagas disease across studies was 2.0% (95% CI: 1.0–4.0). A high degree of heterogeneity was found among studies (I2 > 75%; p < 0.001). The publication bias was not statistically significant (Egger’s test, p = 0.078). The highest pooled prevalences were found in the adult population (3.0%, 95% CI: 1.0–4.0), pregnant women (3.0%, 95% CI: 3.0–4.0) and the Orinoco region (7.0%, 95% CI: 2.2–12.6). Conclusions The results indicate that the T. cruzi-infected population is aging, the adult population, pregnant women and that the Orinoco region (department of Casanare) have the highest prevalences. These results highlight the need to maintain screening and surveillance programs to identify people with chronic T. cruzi infections.

Abstract
BACKGROUND Patients with excellent response to initial therapy have a low rate of tumor recurrence. The objectives of this study were to evaluate the rate of early tumor recurrence in patients with intermediate-risk papillary thyroid cancer who had an excellent response to initial treatment and to identify risk factors. METHODS This retrospective cohort study included 217 patients with American Thyroid Association intermediate-risk papillary thyroid cancer who had a documented excellent response to initial treatment (total thyroidectomy and adjuvant therapy with 100-150 mCi [3.7-5.5 GBq] of radioactive iodine [RAI]). The assessed outcome was recurrence, defined as new evidence of disease after any disease-free period. Multivariate logistic regression and Cox regression models were used to determine the factors associated with recurrence upon recording clinical, surgical, and pathology variables. RESULTS Sixteen (7.4%) cases of recurrent disease were documented after a median follow-up period of 42 months (range 17-88 months). Structural recurrence was documented in 10 (62.5%) patients, and biochemical recurrence was documented in the remaining six patients. The logistic regression model identified a significant association between early recurrence and pN1b involvement (odds ratio [OR] = 10.81 [confidence interval (CI) 1.87-62.59]), lateral neck RAI uptake (OR = 6.06 [CI 1.67-22]), and pre-ablation thyroglobulin >10 ng/mL (OR = 4.01 [CI 1.16-13.85]). Variables that proved significant in the Cox regression model were: pN1b involvement (hazard ratio = 9.6 [CI 1.91-48.52]) and lateral neck RAI uptake (hazard ratio = 5.95 [CI 1.86-18.97]). CONCLUSION The observed early recurrence rate of 7.4% is uncharacteristically high for a population of patients who had an excellent response to initial treatment. The significant association that was found between recurrent disease and lateral neck lymph node metastasis, lateral neck I131 uptake in post-therapy whole-body scan, and pre-ablation thyroglobulin levels >10 ng/mL indicates that early recurrence (<5 years) most likely indicates progression of micrometastatic disease already present at diagnosis and unsuccessfully eradicated with initial therapy.
