Historia de los Servicios de Salud Penitenciarios en Costa Rica / History of Prison Health Services in Costa Rica

La historia de los servicios médicos penitenciarios se remonta hace aproximadamente medio siglo, en la extinta Penitenciaria Nacional, donde al igual que, durante mucho tiempo estuvo a cargo de personeros de la Caja Costarricense del Seguro Social (CCSS). No es, hasta que al finalizar la década de los 80's, con el cierre del centro penal ubicado en la Isla San Lucas, se logra concretar la creación de plazas de salud propias del Ministerio de Justicia y Paz (MJP). En 1993 se logra el primer convenio interinstitucional entre la CCSS y el MJP, actualizado en 1998, el cual aún se encuentra refrendado por la Procuraduría General de la República. Actualmente, el MJP cuenta con 87 plazas asignas a puestos relacionados con servicios de salud a lo largo y ancho del territorio costarricense.

The history of prison medical services goes back approximately half a century, in the now extinct National Penitentiary, where, for a long time, it was in charge of representatives of CCSS. It is not, until at the end of the 80's, with the closure of the penal center located on San Lucas Island, the creation of health centers belonging to the Ministerio de Justicia y Paz (MJP) is achieved. In 1993, the first inter-institutional agreement between the CCSS and the MJP was reached, updated in 1998, which is still endorsed by the Attorney General's Office. Currently, the MJP has 87 positions assigned to positions related to health services throughout the Costa Rican territory.

Prevalencia de enfermedades crónicas no transmisibles en las personas privadas de la libertad en Costa Rica / Prevalence of chronic noncommunicable diseases in persons deprived of liberty in Costa Rica

Mediante un estudio cuantitativo, descriptivo y de corte transversal se realiza una comparación entre la población penal de la Unidad de Atención Integral (UAI) 20 de diciembre y la población penal total costarricense. Hasta no hace mucho tiempo, en el ámbito penitenciario se ha experimentado un cambio importante en la morbimortalidad de las personas privadas de la libertad, pasando de un modelo casi unicausal de origen infeccioso, a procesos de etiología múltiple, con desarrollo poco predecible y alto porcentaje del gasto público sanitario. En el siguiente estudio se determina la similitud existente en prevalencia de enfermedades crónicas no trasmisibles tanto a nivel país, sistema penitenciario nacional y UAI 20 de diciembre.

Through a quantitative, descriptive and cross-sectional study, a comparison is made between the prison population of the Unidad de Atención Integral (UAI) 20 de diciembre and the total Costa Rican prison population. Until recently, there has been an important change in the morbimortality of persons deprived of liberty in the penitentiary environment, going from an almost unicausal model of infectious origin, to processes of multiple etiology, with little predictable development and a high percentage of public health expenditure. The following study determines the existing similarity in the prevalence of chronic non-communicable diseases at the country level, the national prison system and the UAI December 20.

Description of a Swine Infant Model of Volume-Controlled Hemorrhagic Shock.

Hemorrhagic shock is a leading cause of morbidity and mortality in pediatric patients. Interpretation of the clinical indicators validated in adults to guide resuscitation and comparison between different therapies is difficult in children due to the inherent heterogeneity of this population. As a result, compared to adults, appropriate management of pediatric hemorrhagic shock is still not well established. In addition, the scarcity of pediatric patients with hemorrhagic shock precludes the development of clinically relevant studies. For this reason, an experimental pediatric animal model is necessary to study the effects of hemorrhage in children as well as their response to different therapies. We present an infant animal model of volume-controlled hemorrhagic shock in anesthetized young pigs. Hemorrhage is induced by withdrawing a previously calculated blood volume, and the pig is subsequently monitored and resuscitated with different therapies. Here, we describe a precise and highly reproducible model of hemorrhagic shock in immature swine. The model yields hemodynamic data that characterizes compensatory mechanisms that are activated in response to severe hemorrhage.

Multicenter randomized clinical trial comparing dexamethasone versus placebo in preventing upper airway obstruction after extubation in critically ill children.

To analyze the effectiveness of dexamethasone in preventing upper airway obstruction (UAO) symptoms after extubation and the need of reintubation in critically ill children. Multicenter, prospective, double-blind, randomized, phase IV clinical trial involving five pediatric intensive care units. Children between 1 month and 16 years-of-age intubated for more than 48 h were included. Patients were randomized to receive placebo or dexamethasone 0.25 mg/kg every 6 h, 6-to-12 h prior to extubation (four doses). 48 h follow-up was carried out after extubation. Severity of UAO symptoms (Taussig score, stridor) and reintubation requirement were compared. 147 patients were randomized (10 were excluded), 70 patients received dexamethasone and 67 placebo. No global differences were found in the presence of stridor or moderate-to-severe UAO symptoms (Taussig ≥ 5), but Taussig ≥ 5 was less frequent in patients less than 2 years-of-age treated with steroids (p = 0.014). Median Taussig score was lower in the dexamethasone group 1 h after extubation, p < 0.001. 27 patients required reintubation, 9 due to UAO: 3 (4.3%) in the dexamethasone group and 6 (8.9%) in the placebo group, p = 0.319. In those intubated > 5 days, reintubation due to UAO was higher in the placebo group (2.4% vs. 14.3, p = 0.052). Nebulized epinephrine and budesonide were required more frequently in the placebo group in the first 2 h (p = 0.041) and 1 h (p = 0.02) after extubation, respectively. No relevant side effects were observed. Dexamethasone prior to extubation did not significantly reduce moderate-severe UAO symptoms, except for patients under 2-years of age. Dexamethasone could decrease Taussig score and the need of rescue therapies, as well as reintubation rates in those intubated for more than 5 days.

Microcirculatory Changes in Pediatric Patients During Congenital Heart Defect Corrective Surgery.

A prospective, observational single-center study was carried out. Pediatric patients undergoing congenital heart defect surgery were evaluated before, during, and after surgery. At each time point, sublingual microcirculation and clinical parameters were assessed, along with analytical variables. Twenty-four patients were included. All microcirculatory parameters worsened during cardiopulmonary bypass and returned to baseline values after surgery (p ≤ 0.001). In the intraoperative evaluation, body temperature correlated with perfused small vessel density (p = 0.014), proportion of perfused small vessels (p < 0.001), small vessel microvascular flow index (p = 0.003), and small vessel heterogeneity index (p < 0.002). Patients with cyanotic disease exhibited higher small vessel density (p < 0.008) and higher density of perfused small vessels (p < 0.022) at baseline, and a lower microvascular flow index (p = 0.022) and higher heterogeneity (p = 0.026) in the intraoperative phase. Children with congenital heart disease exhibited decreased vascular density and microvascular blood flow and increased heterogeneity during cardiopulmonary bypass. All these parameters returned to baseline values after surgery.

A comparative two-cohort study of pediatric patients with long term stay in ICUs.

During the last decades, the number of patients with long stay admissions (LSA) in PICU has increased. The purpose of this study was to identify factors associated with PICU LSA, assessing healthcare resources use and changes in the profile of these patients. A retrospective, observational, single-center study was carried out. Characteristics of LSA were compared between two periods (2006-2010 and 2011-2015). During the earlier period there were 2,118 admissions (3.9% of them LSA), whereas during the second period, there were 1,763 (5.4% of them LSA) (p = 0.025). LSA accounted for 33.7% PICU stay days during the first period and 46.7% during the second (p < 0.001). Higher use of non-invasive ventilation (80.2% vs. 37.8%, p = 0.001) and high-flow oxygen therapy (68.8% vs. 37.8%, p = 0.005) was observed in the 2011-2015 cohort, whereas the use of arterial catheter (77.1% vs. 92.6%, p = 0.005), continuous infusion of adrenaline (55.2% vs. 75.9%, p = 0.004), and hemoderivative transfusion (74% vs. 89.2%, p = 0.010) was less frequent. In the 2006-2010 cohort, hospital-acquired infections were more common (95.2% vs. 68.8%, p < 0.001) and mortality was higher (26.8% vs. 13.8%, p = 0.026). The number of long-stay PICU admissions have increased entailing an intensive use of healthcare resources. These patients have a high risk for complications and mortality.

[Ultrasound-guided cannulation or by pulse palpation in the intensive care unit]. / Canalización arterial ecoguiada o por palpación del pulso en la unidad de cuidados intensivos.

INTRODUCTION: Ultrasound (US) guidance increases the success rate and decreases complications during central venous catheterisation (CVC). The benefits of US guidance in arterial catheterisation are less clear. The aim of this study is to compare the outcomes of US-guided arterial catheterisation with the traditional landmark (LM) technique in critically ill children. METHODS: A prospective multicentre study was carried out in 18 Paediatric Intensive Care units in Spain during a 6-months period. Ultrasound guided and landmark techniques were compared in terms of cannulation technical success and immediate mechanical complications. RESULTS: A total of 161 procedures were performed on 128 patients (78 procedures in the US group and 83 in the LM groups). The median (interquartile range) age and weight of the cohort was 11months (2-52), and 10kg (4-17), respectively. More than half (59.6%) were male. US was used mainly in big (number of beds 11 [8-16] vs 6 [4-10], p < 0,001) and high complexity intensive care units (cardiac surgery program 76.9% vs. 25.6%, P<.001) as well as in smaller children [weight 5.7kg (3.8-13) vs 11.5kg (4.9-22.7), P<.001]. Almost half (49.7%) of the procedures were performed by an inexperienced operator (paediatric resident, or staff with less than 5years of clinical experience in the PICU), and only 24.4% had performed more than 50 US-guided vascular access procedures before the study. There were no significant differences between US and LM techniques in terms of first-attempt success (35.8% vs 33.7%, P=.773), overall success (75.6% vs 71.1%, P=.514), number of puncture attempts [2 (1-4) vs 2 (1-3), P=.667] and complications (16.6% vs 25.6%, P=.243). Adjustment by potential confounders using multivariate regression models did not modify these results. Subgroup analyses showed that US outperformed LM technique in terms of overall success (83.7% vs 62.7%, P=.036) and complications (10,8% vs 32.5%, P=.020) only when procedures where performed by less-experienced operators. CONCLUSIONS: In this prospective observational multicentre study, US did not improve arterial cannulation outcomes compared to the traditional LM technique in critically ill children. US-guided arterial cannulation may offer advantages when cannulation is performed by inexperienced operators.

Severe manifestations of SARS-CoV-2 in children and adolescents: from COVID-19 pneumonia to multisystem inflammatory syndrome: a multicentre study in pediatric intensive care units in Spain.

BACKGROUND: Multisystem inflammatory syndrome temporally associated with COVID-19 (MIS-C) has been described as a novel and often severe presentation of SARS-CoV-2 infection in children. We aimed to describe the characteristics of children admitted to Pediatric Intensive Care Units (PICUs) presenting with MIS-C in comparison with those admitted with SARS-CoV-2 infection with other features such as COVID-19 pneumonia. METHODS: A multicentric prospective national registry including 47 PICUs was carried out. Data from children admitted with confirmed SARS-CoV-2 infection or fulfilling MIS-C criteria (with or without SARS-CoV-2 PCR confirmation) were collected. Clinical, laboratory and therapeutic features between MIS-C and non-MIS-C patients were compared. RESULTS: Seventy-four children were recruited. Sixty-one percent met MIS-C definition. MIS-C patients were older than non-MIS-C patients (p = 0.002): 9.4 years (IQR 5.5-11.8) vs 3.4 years (IQR 0.4-9.4). A higher proportion of them had no previous medical history of interest (88.2% vs 51.7%, p = 0.005). Non-MIS-C patients presented more frequently with respiratory distress (60.7% vs 13.3%, p < 0.001). MIS-C patients showed higher prevalence of fever (95.6% vs 64.3%, p < 0.001), diarrhea (66.7% vs 11.5%, p < 0.001), vomits (71.1% vs 23.1%, p = 0.001), fatigue (65.9% vs 36%, p = 0.016), shock (84.4% vs 13.8%, p < 0.001) and cardiac dysfunction (53.3% vs 10.3%, p = 0.001). MIS-C group had a lower lymphocyte count (p < 0.001) and LDH (p = 0.001) but higher neutrophil count (p = 0.045), neutrophil/lymphocyte ratio (p < 0.001), C-reactive protein (p < 0.001) and procalcitonin (p < 0.001). Patients in the MIS-C group were less likely to receive invasive ventilation (13.3% vs 41.4%, p = 0.005) but were more often treated with vasoactive drugs (66.7% vs 24.1%, p < 0.001), corticosteroids (80% vs 44.8%, p = 0.003) and immunoglobulins (51.1% vs 6.9%, p < 0.001). Most patients were discharged from PICU by the end of data collection with a median length of stay of 5 days (IQR 2.5-8 days) in the MIS-C group. Three patients died, none of them belonged to the MIS-C group. CONCLUSIONS: MIS-C seems to be the most frequent presentation among critically ill children with SARS-CoV-2 infection. MIS-C patients are older and usually healthy. They show a higher prevalence of gastrointestinal symptoms and shock and are more likely to receive vasoactive drugs and immunomodulators and less likely to need mechanical ventilation than non-MIS-C patients.

[Point-of-care ultrasound: Is it time to include it in the paediatric specialist training program?] / Ecografía a pie de cama: ¿es el momento de incluirla en la formación del pediatra?

Point-of-care ultrasound (POCUS) has become an essential tool for clinical practice in recent years. It should be considered as an extension of the standard physical examination, which complements and enriches it without substituting it. POCUS enables the physician to answer specific clinical questions about the diagnosis, to understand better the pathophysiological context, to orientate the treatment, and to perform invasive procedures more safely. Despite its current use in many centres, and in most paediatric sub-specialties, there are currently no specific recommendations addressing educational aims in the different training areas, as well as methodology practice and the certification process in paediatrics. These ingredients are essential for POCUS implementation in daily practice, with a quality guarantee in terms of efficiency and safety. Several POCUS experts in different paediatric medicine environments performed a non-systematic review addressing the main paediatric POCUS applications in paediatrics. The lack of educational programs in POCUS in Spain is also discussed, and the experience in the United States of America in this topic is provided. Considering the current situation of POCUS in paediatrics, we strongly believe that it is urgent to establish evidence-based recommendations for POCUS training that should be the base to develop educational programs and to include POCUS in the paediatric residency training.

Ultrasound-guided or landmark techniques for central venous catheter placement in critically ill children.

PURPOSE: To assess whether ultrasound guidance improves central venous catheter placement outcomes compared to the landmark technique in critically ill children. METHODS: A prospective multicentre observational study was carried out in 26 paediatric intensive care units over 6 months. Children 0-18 years old who received a temporary central venous catheter, inserted using either ultrasound or landmark techniques, were eligible. The primary outcome was the first-attempt success rate. Secondary outcomes included overall placement success, number of puncture attempts, number of procedures requiring multiple punctures (> 3 punctures), number of procedures requiring punctures at more than one vein site and immediate mechanical complications. To account for potential confounding factors, we used propensity scores. Our primary analysis was based on 1:1 propensity score matching. The association between cannulation technique and outcomes in the matched cohort was estimated using generalized estimating equations and mixed-effects models to account for patient-level and hospital-level confounders. RESULTS: Five hundred central venous catheter-placement procedures involving 354 patients were included. Ultrasound was used for 323 procedures, and the landmark technique was used for 177. Two hundred and sixty-six procedures were matched (133 in the ultrasound group and 133 in the landmark group). Ultrasound was associated with an increase in the first-attempt success rate [46.6 vs. 30%, odds ratio 2.09 (1.26-3.46); p < 0.001], a reduced number of puncture attempts [2 (1-3) vs. 2 (1-4), B coefficient - 0.51 (95% confidence interval - 1.01 to - 0.03), p = 0.035], and fewer overall mechanical complications [12 vs. 22.5%, odds ratio 0.47 (95% confidence interval 0.24-0.91), p = 0.025] in the matched cohort. The number of puncture attempts was the main factor associated with overall complications. CONCLUSIONS: Compared with the landmark technique, ultrasound guidance was associated with an increased first-attempt success rate, a reduced number of puncture attempts, and fewer complications during central venous catheter placement in critically ill children.

[Point-of-care ultrasound in Spanish paediatric intensive care units]. / Ecografía en el punto de cuidado en las unidades de cuidados intensivos pediátricos españolas.

INTRODUCTION: Point-of-care (bedside) ultrasound is being increasingly used by paediatricians who treat critically ill children. The aim of this study is to describe its availability, use, and specific training in Paediatric Intensive Care Units in Spain. MATERIAL AND METHODS: A descriptive, cross-sectional, multicentre study was performed using an online survey. RESULTS: Of a total of 51 PICUs identified in our country, 64.7% responded to the survey. Just over half (53.1%) have their own ultrasound machine, 25% share it, with other units with the usual location in the PICU, and 21.9% share it, but it is usually located outside the PICU. Ultrasound machine availability was not related to size, care complexity, or number PICU admissions. The ultrasound was used daily in 35% of the units, and was associated with location of the machine in the PICU (P=.026), the existence of a transplant program (P=.009), availability of ECMO (P=.006), and number of admissions (P=.015). 45.5% of PICUs has less than 50% of the medical staff specifically trained in bedside ultrasound, and 18.2% have all their medical staff trained. The presence of more than 50% of medical staff trained was associated with a higher rate of daily use (P=.033), and with specific use to evaluate cardiac function (P=.033), intravascular volume estimation (P=.004), or the presence of intra-abdominal collections (P=.021). CONCLUSIONS: Bedside ultrasound is frequently available in Spanish PICUs. Specific training is still variable, but it should serve to enhance its implementation.

Diffuse persistent pulmonary interstitial emphysema secondary to mechanical ventilation in bronchiolitis.

BACKGROUND: Persistent interstitial pulmonary emphysema (PIE) is a rare disease and it is even more uncommon in full-term infants, like our patient. When conservative management is not successful, surgical treatment should be considered. In our case, ECMO support was iniciated to keep the patient ventilated in order to allow the lung to heal using lung protection strategies. CASE PRESENTATION: We report an 18-day-old male infant with bronchiolitis that required mechanical ventilation with high positive airway pressures due to severe respiratory insufficiency. Chest X-rays and computed tomography scan revealed a severely hyperinflated left lung with extensive destructive changes and multiple small bullae. These findings were consistent with diffuse persistent interstitial emphysema (PIE), probably due to mechanical ventilation. The patient required high frequency oscillatory ventilation, inotropic support and continuous renal replacement therapy. He eventually suffered a cardiac arrest that required cardiopulmonary resuscitation and ECMO during 5 days with progressive clinical improvement and normalization of the X-ray. CONCLUSION: We present a patient with diffuse persistent interstitial emphysema who, despite an unfavorable evolution with different mechanical ventilation strategies, had a good response after ECMO assistance.
