An optimal model for telemedicine use in the international care setting has not been established. Our objective was to describe variables associated with patient outcome during the implementation of an international pediatric cardiac critical care (PCCC) telemedicine program. A retrospective review was performed of clinical records and a telemedicine database of patients admitted to the cardiac intensive care unit (CICU) at the Fundacion Cardiovascular de Colombia, Bucaramanga, Colombia, during the initial 10 months of our program, compared with patients admitted during a previous period. Information collected included demographic data, cardiac diagnosis and associated factors, Risk Adjustment for Congenital Heart Surgery (RACHS)-1 classification, and perioperative events. Primary outcome was composed of CICU and hospital mortality. Secondary outcomes were CICU and hospital length of stay (LOS). Of the 553 patients who were included, teleconsultation was done for 71 (12.4%), with a total of 156 encounters, including 19 for patients on extracorporeal membrane oxygenation. Three hundred twenty-one recommendations were given, and 42 real-time interventions were documented. RACHS-1 distribution was similar between study periods (p=0.427). Teleconsulted patients were significantly younger (44 versus 24 months; p=0.03) and had higher surgical complexity than nonteleconsulted patients (p=0.01). RACHS-1 adjusted hospital survival was similar between study periods. CICU and hospital LOS intervals were significantly shorter in the telemedicine period (10 versus 17 days [p=0.02] and 22 versus 28 days [p<0.001]). In surgical cases, preoperative CICU LOS was significantly shorter (3 versus 6 days; p<0.001). Variables associated with hospital mortality were higher RACHS-1 categories, lower weight, bypass time longer than 150 min, and use of circulatory arrest, as well as the presence of sepsis or necrotizing enterocolitis. Those associated with increased LOS were lower weight, extracorporeal membrane oxygenation, and cross-clamp time longer than 60 min. An international telemedicine service in PCCC was associated with lower CICU and hospital LOS. Prospective telemedicine interventions aimed to decrease mortality and LOS should focus on patients with higher RACHS-1 categories, lower-weight infants, and those with prolonged operative time and selective perioperative complications.

Background: Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality worldwide, with a prevalence of approximately 100 million patients. There is evidence that antiplatelet agents and antihypertensive medications could reduce the risk of new vascular events in this population; however, treatment adherence is very low. An SMS text messaging intervention was recently developed based on behavior change techniques to increase adherence to pharmacological treatment among patients with a history of ASCVD. Objective: This study aims to evaluate the efficacy and safety of an SMS text messaging intervention to improve adherence to cardiovascular medications in patients with ASCVD. Methods: A randomized controlled clinical trial for patients with a prior diagnosis of cardiovascular events, such as acute myocardial infarction, unstable angina, cerebrovascular disease, or peripheral artery disease, in one center in Colombia was conducted. Patients randomized to the intervention arm were assigned to receive SMS text messages daily for the first 4 weeks, 5 SMS text messages on week 5, 3 SMS text messages each in weeks 6 and 7, and 1 SMS text message weekly from week 8 until week 52. In contrast, patients in the control arm received a monthly SMS text message reminding them of the next study appointment and the importance of the study, requesting information about changes in their phone number, and thanking them for participating in the study. The primary endpoint was the change in low-density lipoprotein cholesterol (LDL-C) levels, whereas the secondary endpoints were the changes in thromboxane B2 levels, heart rate, systolic and diastolic blood pressure, medication adherence, cardiac and noncardiac mortality, and hospitalization. Linear regression analyses and bivariate tests were performed. Results: Of the 930 randomized patients, 805 (86.5%) completed follow-up and were analyzed for the primary endpoint. There was no evidence that the intervention changed the primary outcome (LDL-C levels; P=.41) or any of the secondary outcomes evaluated (all P>.05). There was also no evidence that the intervention was associated with adverse events. Conclusions: In this study, there was no evidence that a behavior modification intervention delivered by SMS text messaging improved LDL-C levels, blood pressure levels, or adherence at 12 months. More research is needed to evaluate whether different SMS text messaging strategies, including personalized messages and different timings, are effective; future studies should include mixed methods to better understand why, for whom, and in which context (eg, health system or social environment) SMS text messaging interventions work (or not) to improve adherence in patients with ASCVD.

Less than 1% of the extracorporeal life support organization (ELSO) registry patients are from South America. Extracorporeal membrane oxygenation (ECMO) is an expensive therapy not only in terms of direct financial cost but also with respect to technical and human resources. Finding a successful ECMO model that developing countries can afford is critical to the expansion of therapy to include the availability of this technology for patients in the developing world. We retrospectively studied the first 104 pediatric ECMO patients in the Fundacion Cardiovascular de Colombia between May 2007 and May 2013. We collected the ELSO registry data from electronic medical records to determine the survival rate, mortality risk factors, and complications in pediatric patients who received ECMO support for cardiac failure, respiratory failure, or ECMO for extracorporeal cardiopulmonary resuscitation in the setting of refractory cardiopulmonary resuscitation. We describe our model of ECMO care regarding staff, training process, care protocol, ECMO circuit, and costs. Of 104 patients, 82 were diagnosed with congenital heart disease. Of those, 50 had biventricular and 32 had univentricular physiology, with a significantly higher survival rate at discharge in the biventricular group (44% vs 18.7%, odds ratio [OR] 3.6, 95% confidence interval [CI] = 1.28-10.52, P = .01). Pediatric patients with a cardiac indication had survival rates of 76.3% at weaning and 52.6% at discharge, which is roughly comparable to those reported by the ELSO in 2013. Univentricular physiology, ECPR, severe pre-ECMO acidosis, ECMO-associated renal failure, and duration of ECMO support were factors associated with increased mortality. Despite limited availability of technical and economic resources, ECMO therapy can be done successfully in a developing country. A model of care based on nurses as ECMO specialists, supported by a multidisciplinary team, is cost-effective.

Introducción: Se considera "Aglomeración" cuando un servicio de urgencias excede el número de pacientes que tiene capacidad de atender o no cuenta con las condiciones para cubrir las necesidades del próximo paciente a ser atendido. Este estudio evalúa el sobrecupo del servicio de urgencias en un hospital de Colombia.Objetivo: Comparar la escala objetiva de NEDOCS con la escala subjetiva del personal de salud en el departamento de urgencias para evaluar la diferencia entre ambas.Métodos: Se aplicó la escala NEDOCS y una escala subjetiva de sobrecupo en el servicio de urgencias al personal médico y enfermera jefe de turno durante 3 semanas seguidas, 6 veces al día (6:00 a.m., 9:00 a.m., 12:00 p.m., 3:00 p.m., 6:00 p.m., 9:00 p.m.). Se realizaron análisis de correlación y medida de concordancia para evaluar los diferentes resultados.Resultados: La mediana de NEDOCS para el total de datos fue de 137, se presentó una correlación moderadamente positiva entre la escala NEDOCS objetiva con respecto a la subjetiva Rho 0.58 (p <0.001), del total de respuestas en los momentos de mayor congestión el 87% de las valoraciones subjetivas del personal de salud fueron subestimar el nivel de Sobrecupo.Conclusiones: Cuando los niveles de sobrecupo clasificados por NEDOCS son iguales o superiores a nivel 5 (Severamente congestionado y peligrosamente congestionado) el personal de salud no tiene una percepción del riesgo por sobrecupo del departamento de urgencias, lo que conlleva a un riesgo en la seguridad y atención del paciente.

Introduction: Anti-platelet therapy, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta-blockers and statins are cost-effective in patients with atherosclerotic cardiovascular diseases (ASCVD) for reducing the risk of ASCVD events. Unfortunately, there is abundant evidence that adherence to these cardiovascular medications is far from ideal. A recent Cochrane review showed a potential beneficial effect of Short Message Service (SMS) interventions on adherence to medication in ASCVD patients.Methods and analysis: The txt2heart study is a pragmatic randomised single-blind controlled trial. The objective is to evaluate the efficacy and safety of an intervention with SMS messages delivered by mobile phones to improve adherence to cardiovascular medications in patients with ASCVD. The intervention consists of behavioural techniques delivered via SMS. The primary outcome is change in blood serum low-density lipoprotein cholesterol levels as an indicator of adherence to statins. Secondary outcomes will include systolic blood pressure as an indicator of adherence to blood-lowering therapies and heart rate as an indicator of adherence to beta-blockers, urine levels of11-dehydrothromboxane B2, self-reported adherence to cardiovascular medications and rates of cardiovascular death or hospitalisation due to cardiovascular disease.Ethics and dissemination: The study will be performed in compliance with the protocol, regulatory requirements, Good Clinical Practice and ethical principles of the Declaration of Helsinki. The Ethics Committee of Fundación Cardiovascular de Colombia evaluated and approved the trial. The txt2heart Colombia trial aims to provide robust evidence to evaluate whether SMS messages delivered through mobile telephones change the behaviour of Colombian patients who have suffered a cardiovascular event. Trial results will be presented to the local health authorities, and if the intervention is effective and safe, we hope this strategy will be implemented quickly because of its low cost and wide-reaching impact on the population.Trial registration number: NCT03098186.

Cardiovascular diseases are the leading cause of mortality worldwide, for this reason, they are a public health problem. In Colombia, cardiovascular diseases are the main cause of mortality, having a death rate of 152 deaths per 100,000 population. There are 80% of these cardiovascular events that are considered avoidable. The objective of the study is to determine the prevalence of the cardiovascular risk and its associated factors among the institution's workers in order to design and implement interventions in the work environment which may achieve a decrease in such risk. An analytical cross-sectional study was designed to determine the cardiovascular risk and its associated factors among workers of a high complexity health care institution. A self-applied survey will be conducted considering sociodemographic aspects, physical activity, diet, alcohol consumption, smoking, level of perceived stress, and personal and family history. In a second appointment, a physical examination will be made, as well as anthropometric measurements and blood pressure determination. Also, blood samples for evaluating total and high density lipoprotein cholesterol, triglycerides, and fasting blood sugar will be taken. A ten-year global risk for cardiovascular disease will be determined using the Framingham score. A descriptive analysis of the population's characteristics and a stratified analysis by sex, age, and occupation will be made. Bivariate and multivariate analysis will be made using logistic regression models to evaluate the association between cardiovascular risk and the independent variables. The research protocol was approved by the Scientific and Technical Committee and the Ethics Committee on Research of the Fundación Cardiovascular de Colombia. The protocol has already received funding and the enrollment phase will begin in the coming months. The results of this study will give the foundation for the design, implementation, and evaluation of a program based on promoting healthy lifestyles, such as performing regular physical activity and healthy food intake in order to avoid and/or control the cardiovascular risk in the workers of a high complexity health care institution.
