Two-Year Experience of a Center of Excellence for the Comprehensive Management of Non-Small Cell Lung Cancer at a Fourth-Level Hospital in Bogota, Colombia: Observational Case Series Study and Retrospective Analysis

Background: This study aimed to provide a comprehensive analysis of 56 patients admitted to the Lung Cancer Clinical Care Center (C3) at Fundación Santa Fe de Bogotá (FSFB) between 2 May 2022 and 22 April 2024. The focus was on demographic characteristics, smoking history, comorbidities, lung cancer types, TNM classification, treatment modalities, and outcomes. Methods: This observational case series study reviewed medical records and included patients over 18 years with a confirmed diagnosis of non-small cell lung cancer (NSCLC). Data were collected and analyzed for demographics, comorbidities, treatment types, biomolecular profiling, and survival rates. Ethical approval was obtained, and data were anonymized. Results: The mean age was 71.8 years with a female predominance (53.6%). A history of smoking was present in 71.4% of patients. Adenocarcinoma was the most common type (75.0%), followed by squamous cell carcinoma (19.6%). At admission, the most frequent TNM stages were IA2 (17.9%) and IVA (16.1%). One-year survival was 68.8%, and 94.3% of stage I–IIIA patients underwent PET scans. Biomolecular profiling revealed 69.2% non-mutated EGFR, 90.4% ALK-negative, and various PDL-1 expression levels. Immunotherapy was received by 91.4% of patients, with Alectinib and Osimertinib being common. Grade III–IV pneumonitis occurred in 5.4% of patients. Conclusions: The study’s findings align with existing literature, highlighting significant smoking history, common adenocarcinoma, and substantial use of immunotherapy. Limitations include the observational design, small sample size, and short follow-up period, impacting the generalizability and long-term outcome assessment. Future research should address these limitations and explore longitudinal outcomes and emerging therapies.

Factors of poor prognosis in newborns with a prenatal diagnosis of gastroschisis in Bogota, Colombia.

To identify factors associated with poor prognoses in newborns with a prenatal diagnosis of gastroschisis in eight hospitals in Bogota, Colombia, from 2011 to 2022. A multi-center retrospective case-control study was conducted on newborns with gastroschisis in eight hospitals in Bogota, Colombia. Poor prognosis was defined as the presence of sepsis, intestinal complications, or death. The study included 101 patients. Preterm newborns under 32weeks had a poor neonatal prognosis (OR 6.78 95 % CI 0.75-319). Oligohydramnios (OR 4.95 95 % CI 1.15-21.32) and staged closure with silo (OR 3.48; 95 % CI 1.10-10.96) were risk factors for neonatal death, and intra-abdominal bowel dilation of 20-25 mm was a factor for the development of intestinal complications (OR 3.22 95 % CI 1.26-8.23). Intra-abdominal bowel dilation between 20 and 25 mm was associated with intestinal complications, while oligohydramnios was associated with the risk of perinatal death, requiring increased antenatal surveillance of fetal wellbeing. Management with primary reduction when technically feasible is recommended in these infants, considering that the use of silos was associated with higher mortality.

Prediction of pharmaceutical and non-pharmaceutical expenditures associated with Diabetes Mellitus type II based on clinical risk.

To assess the effectiveness of different machine learning models in estimating the pharmaceutical and non-pharmaceutical expenditures associated with Diabetes Mellitus type II diagnosis, based on the clinical risk index determined by the analysis of comorbidities. In this cross-sectional study, we have used data from 11,028 anonymized records of patients admitted to a high-complexity hospital in Bogota, Colombia between 2017-2019 with a primary diagnosis of Diabetes. These cases were classified according to Charlson's comorbidity index in several risk categories. The main variables analyzed in this study are hospitalization costs (which include pharmaceutical and non-pharmaceutical expenditures), age, gender, length of stay, medicines and services consumed, and comorbidities assessed by the Charlson's index. The model's dependent variable is expenditure (composed of pharmaceutical and non-pharmaceutical expenditures). Based on these variables, different machine learning models (Multivariate linear regression, Lasso model, and Neural Networks) were used to estimate the pharmaceutical and non-pharmaceutical expenditures associated with the clinical risk classification. To evaluate the performance of these models, different metrics were used: Mean Absolute Percentage Error (MAPE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and Coefficient of Determination (R2). The results indicate that the Neural Networks model performed better in terms of accuracy in predicting pharmaceutical and non-pharmaceutical expenditures considering the clinical risk based on Charlson's comorbidity index. A deeper understanding and experimentation with Neural Networks can improve these preliminary results, therefore we can also conclude that the main variables used and those that were proposed can be used as predictors for the medical expenditures of patients with diabetes type-II. With the increase of technology elements and tools, it is possible to build models that allow decision-makers in hospitals to improve the resource planning process given the accuracy obtained with the different models tested.

(O-06) PREVALENCE OF CLIMACTURIA IN POST RADICAL PROSTATECTOMY PATIENTS IN REFERRAL HOSPITAL IN BOGOTA

Abstract Introduction Climacturia is a frequent complication of radical prostatectomy (RP). Pelvic floor involvement and urinary sphincter functionality play a vital role in its pathophysiology. The prevalence in Colombia is unknown, and it is currently an underdiagnosed entity. This study aims to estimate the prevalence of climacturia in men undergoing RP in a fourth-level hospital in Bogota from 2018 to 2023. Methodology A descriptive cross-sectional observational study was conducted. Patients who attended postoperative control for 6 months and 1 year after a RP in the institution were included. A standardized survey was applied evaluating the presence of urine leakage during sexual arousal and/or orgasm and standardized scales of urinary incontinence and sexual function. Results Forty-four patients were included. The mean age of the patients was 64.7 (range: 45-81). The distribution of the surgical approach used in these patients is shown in Table 1. 56,8% (n=25) reported urine leakage during arousal. Of these patients, 43.1% (n=19) had received robot-assisted radical prostatectomy (RARP), followed by open surgery with 13,6% (n=6) of patients reporting this symptom. On the other hand, 38,6% (n=17) of patients had urine leakage during orgasm, of which the highest proportion of this symptom was open surgery. A limitation of the study was the lack of active search for this pathology in the general urological consultation and the poor response of patients to the forms. Conclusions The prevalence of climacturia is high and its diagnosis has multiple limitations. In addition, other post-prostatectomy side effects were identified, such as urine leakage with arousal, whose prevalence was higher than that of climacturia and may affect the sexuality of patients. Additionally, considering these are the preliminary findings from a prospective study, a larger sample size is required to achieve more representative results. Financing No conflict.

Impact of presentation timing in metastatic hormone-sensitive prostate cancer: Characterization of patients and identification of prognostic factors.

The treatment and surveillance of metastatic hormone-sensitive prostate cancer (mHSPC) has evolved since the introduction of several treatment intensification options associated with hormonal blockade and classifications based on the timing of metastatic disease presentation and disease volume. Using a hospital-based registry, we aimed to assess whether these new classifications are applicable to our population, as few studies have demonstrated their prognostic value for overall survival (OS) and time to development of castration-resistant prostate cancer (CRPC), and to establish prognostic factors in our population. A retrospective cohort of mHSPC patients who were attended at an oncology referral hospital in Bogota between 2017 and 2021 were included in this study. The primary and secondary endpoints were OS and time to CRPC. The distribution of outcome measures was estimated using the Kaplan-Meier method. Proportional hazard models were constructed using the Cox regression approach and stratified according to risk factors. The study cohort included 373 patients. The median castration resistance-free survival was 48 months (CI: 32-73 months), and OS was 43 months (CI: 37-48 months). In multivariate analysis, nodal staging, ECOG status, and surgical castration were independent prognostic factors. In our hospital-based registry, the independent impact of the time of presentation on castration-resistant-free survival or OS could not be demonstrated, nor could the grouping of prognostic categories based on metastatic presentation temporality and volume. Other independent prognostic factors have been proposed.

Characterization in end-of-life care of older people attended by geriatricians

Background and objectiveSymptom control at the end of life is essential, and palliative sedation is a viable intervention option for the care of terminally ill patients. This study aims to characterize the elderly population receiving end-of-life care plans and their management with palliative sedation in a geriatric unit at a high complexity hospital. Materials and methodsA cross-sectional study was conducted, and a descriptive analysis was performed. Medical records of 163 patients admitted to a high complexity hospital in Bogota, Colombia between January 2016 and December 2019 were reviewed. ResultsFrom 163, 141 patients received an end-of-life care plan, and 22 were managed with palliative sedation. The mean age was 84 years, the most frequent cause of death was respiratory infections and 44% of patients had a history of cancer. Prior to admission, functional decline and the presence of moderate to severe dementia were frequently found. About one in ten persons required palliative sedation, which lasted an average of 2.22±5 days. The most common refractory symptom was dyspnea (45.45%), followed by pain (36.36%). ConclusionsPalliative sedation is prevalent in the elderly population and characterizing this population can provide increased knowledge to improve end-of-life care.

In-Hospital Acute Ischemic Stroke Case Fatality: Experience from a University Hospital in Bogota, Colombia (2018-2019).

Introduction Until 2020, stroke was the second cause of death in Colombia and worldwide. In-hospital case fatality accounts for the majority of deaths. Multiple risk factors for in-hospital mortality have been described in the stroke population and their recognition could reduce stroke-related death. Aims To describe a single center experience of in-hospital acute ischemic stroke case fatality and its risk factors. Methodology Single center, retrospective, cross-sectional study between august 2018 and august 2019. Admitted consecutive patients with acute ischemic stroke brain infarct type were included. Admission sociodemographic, clinical, laboratory and imaging studies variables were drawn out. Quantitative variables were summarized as means, medians and interquartile ranges. Bivariate analysis was used to evaluate associations of in-hospital stroke case fatality and imputed variables. Results 402 stroke brain infarct type patients were included, mean age 73,28 years (SD±14,53), 50,4% men. Prevalent vascular risks factors were hypertension (70,90%), diabetes mellitus type 2 (24,13%) and previous stroke (20,90%). There were 13 (3,2%) in-hospital case fatalities. Mean time from admission to death was 11.38 days (SD±10,8). Lower hemoglobin levels (p=0.002), lower total, LDL and HDL serum cholesterol levels (p=0.02), internal carotid artery stenosis >50% by duplex ultrasound (p=0.01) and stroke severity as measured by NIHSS score (p<0,0001) showed association with in-hospital stroke case fatality. Conclusions NIHSS score, hemoglobin level, and cholesterol (total, LDL, HDL) levels upon admission may be used by clinicians to make the appropriate early transfer decisions to facilities with the capacity to offer advance in-hospital stroke care. The cholesterol paradox in acute stroke fatality warrants further studies.

Hallazgos histológicos del corte ungueal en pacientes con psoriasis

IntroductionUngueal psoriasis is observed in up to 80% of cases in patients with psoriasis and in 6% it is the only manifestation, being a predictor of greater severity and psoriatic arthritis. Ungueal clipping is a simple, inexpensive and rapid diagnostic technique that has proven valid in the diagnosis of various nail pathologies. Its usefulness in nail psoriasis is little studied. ObjectiveTo describe the histological findings present in the ungueal cut samples of patients with a diagnosis of psoriasis who consulted the Dermatology service of a referral hospital in Bogota D.C. in 2018. MethodsAn observational, prospective, case series type study was performed. Patients with a diagnosis of psoriasis were included, and sociodemographic, clinical and microscopic variables of the disease were described. Results48 patients with psoriasis entered the study, 50% were women; mean age was 48.1 years (SD 16 years). Plaque psoriasis was the most frequent clinical type with 52.1%, and only 14.6% presented psoriatic arthritis. The most frequent microscopic findings were subungual parakeratosis (91.7%), which was also present in samples from patients without clinically evident changes.

Satisfacción del neurólogo y de los pacientes con diagnóstico de epilepsia en una consulta de seguimiento a través de telemedicina sincrónica en el Hospital San José de Arjona (Bolívar), 2014-2015

Introducción: la gran demanda de pacientes en servicios de consulta especializada de neurología y la poca oferta de profesionales entrenados y médicos especialistas, principalmente en zonas aisladas por circunstancias geográficas o políticas, nos obligan a buscar nuevos recursos como la telemedicina a fin de mejorar el tiempo de consulta.
 Objetivo: explorar el grado de satisfacción del neurólogo y de los pacientes con epilepsia en una consulta por telemedicina en el Hospital San José de Arjona con conexión al Hospital de San José en Bogotá.
 Materiales y métodos: estudio observacional prospectivo en pacientes mayores de 15 años con diagnóstico de epilepsia. Se diligenció el instrumento de evaluación de satisfacción del neurólogo y de los pacientes, que contiene una escala aplicada en Canadá, la cual consta de diecinueve preguntas, validadas en Colombia gracias a la prueba piloto realizada en el 2012 por nuestro Grupo de Neurología y Telemedicina, implementada para evaluar la satisfacción de los pacientes en la consulta de epilepsia por telemedicina. Además, este cuestionario está diseñado según una escala de Thurstone que consta de cinco alternativas de respuesta, las cuales en orden son: "muy en desacuerdo", "en desacuerdo", "neutral", "de acuerdo", "muy de acuerdo".

La satisfacción de dos neurólogos con la consulta de telemedicina se distribuye uniformemente entre "muy de acuerdo" y "de acuerdo".
 Conclusión: según los resultados de este estudio, podemos concluir que tanto los pacientes como los neurólogos que realizaron la consulta guiada por telemedicina están satisfechos con el uso de esta herramienta, siendo este método una alternativa para la atención en salud.

Use of high-flow cannula in pediatric patients with respiratory failure: A prospective cohort study in three high-altitude hospitals.

Acute respiratory failure (ARF) is a common cause of morbimortality, and a frequent reason for admission to the pediatric intensive care unit (PICU).It requires a high-flow oxygen device as treatment. Our aim is to determine the frequency and main indications for the use of high-flow nasal cannula (HFNC), and the prevalence of HFNC failure and its main causes, in three hospitals. It is a multicenter prospective cohort study, developed in three hospitals in Bogota. Eligible patients were children older than 1month and younger than 18 years who presented ARF and required management with an HFNC. The study was carried out between April 2020 and December 2021. The follow-up was carried out at 1, 6, and 48 h after starting the management. Of 685 patients included in the study, 296 developed ARF. The prevalence of patients with ARF who required management with HFNC was 48%. The frequency of the pathologies that cause the ARF was: Bronchiolitis was the most frequent pathology (34.5%), followed by asthmatic crisis (15.5%)and pneumonia (12.7%). The average time of use of HFNC was 81.6 h. Regarding treatment failure with HFNC, 15 patients presented torpid evolution and required invasive mechanical ventilation, with a prevalence of therapeutic failure of the HFNC of 10.6%. The use of HFNC is more frequent in patients with bronchiolitis, in children under 2 years of age and in males, which is in line with what has been reported in the literature. In addition, the failure rate of HFNC is low (10.6%), and it may be useful in other pathologies besides bronchiolitis, such as asthma, pneumonia, among others. It opens the possibility to continue evaluating the role of HFNC in pediatric pathology in new studies.

Incidence, etiology, sociodemographic and clinical characterization of acute respiratory failure in pediatric patients at a high-altitude city: A multicenter cohort study.

Acute respiratory failure is a life-threatening medical condition, associated with a variety of conditions and risk factors, including acute respiratory diseases which are a frequent cause of pediatric morbidity and mortality worldwide. In Colombia, the literature related to ARF is scarce. To determine the incidence, causes, and sociodemographic and clinical characteristics of ARF in three hospitals in Bogota, a high-altitude city located in Colombia, during the COVID-19 pandemic. A multicenter prospective cohort study called the FARA cohort was developed between April 2020 - December 2021. Patients older than one month and younger than 18 years with respiratory distress who developed ARF were included. 685 patients with respiratory distress were recruited in 21 months. The incidence density of ARF was found to be 41.7 cases per 100 person-year CI 95%, (37.3-47.7). The median age was 4.5 years.. Most of the patients consulted during the first 72 h after the onset of symptoms. Upon admission, 67.2% were potentially unstable. The most frequent pathologies were asthma, bronchiolitis, pneumonia, and sepsis. At admission, 75.6% of the patients required different oxygen delivery systems, 29,5% a low-flow oxygen system, 36,8% a high-flow oxygen system, and 9,28% invasive mechanical ventilation. SARS-COV-2, respiratory syncytial virus, rhinovirus/enterovirus, and adenovirus were the most frequently isolated viral agents. The coinfection cases were scarce. This multicenter study, the FARA cohort, developed at 2,600 meters above sea level, shows the first data on incidence, etiology, sociodemographic and clinical characterization in a pediatric population with ARF that also concurs with the COVID-19 pandemic. These results, not only have implications for public health but also contribute to the scientific and epidemiological literature on a disease developed at a high altitude.

Prediction of severe pancreatitis in a population with low atmospheric oxygen pressure

To establish the severity of pancreatitis, there are many scoring systems, the most used are the Marshall and APACHE II systems, each one has advantages and disadvantages; but with good relation regarding mortality and prediction of complications. In populations with low barometric pressures produced by a decrease in atmospheric pressure, there is a decrease in partial pressure of oxygen, in these cases scores which take arterial oxygen partial pressure as one of their variables, may be overestimated. A diagnostic trial study was designed to evaluate the performance of APACHE II, Marshall and BISAP in a city 2640 m above sea level. A ROC analysis was performed to estimate the AUC of each of the scores, to evaluate the performance in predicting unfavorable outcomes (defined as the need for percutaneous drainage, surgery, or mortality) and a non-parametric comparison was made between the AUC of each of the scores with the DeLong test. From January 2018 to December 2019, data from 424 patients living in Bogota, with a diagnosis of gallstone pancreatitis was collected consecutively in a hospital in Bogota, Colombia. The ROC analysis showed AUC for predicting adverse outcomes for APACHE II in 0.738 (95% CI 0.647–0.829), Marshall in 0.650 (95% CI 0.554–0.746), and BISAP in 0.744 (95% CI 0.654–0.835). The non-parametric comparison to assess whether there were differences between the different AUC of the different scores showed that there is a statistically significant difference between Marshall and BISAP AUC to predict unfavorable outcomes (p=0.032). The mortality in the group of patients studied was 5.8%. We suggest the use of BISAP to predict clinical outcomes in patients with a diagnosis of biliary pancreatitis in populations with decreased atmospheric pressure because it is an easy-to-use tool and does not require arterial oxygen partial pressure for its calculation.

Factors associated with COVID-19 contagion in healthcare workers of a level III hospital in Bogota?, Colombia: recommendations for contagion mitigation

Background: The COVID-19 pandemic has had a significant impact on healthcare workers who are at a greater risk of contagion given their higher level of exposure. However, the various factors contributing to this heightened risk have not been identified so far. Objective: To identify the factors associated with COVID-19 contagion in healthcare workers. Methods Cross-sectional study using data from healthcare workers of a high complexity hospital between March 2020 and March 2021. The sociodemographic characteristics of the contagion cases were analyzed, and a Chi2 test was carried out to identify the variables to be measured as part of the multinomial regression. Results: Overall, 382 positive cases were reported in a population of 1544 hospital workers, for an institutional prevalence of 24.74%. Of these, 71.2% were women, 65.8% worked in the clinical area, and the highest percentage of contagion cases occurred among licensed practical nurses (38.22%). A significant association was found between inhospital contagion and all the variables included in the model, with p<0.000 in the adjusted model. Conclusions: The highest percentage of contagions occurred among healthcare professionals working in the clinical area. However, the majority of the cases are the result of inside and outside social contacts and not of patient care. Steps must be taken, considering that clinical staff is essential for managing the current health crisis and learning lessons for future similar circumstances.

Neurological symptoms associated with SARS-CoV-2 infection in a tertiary hospital in Bogota, Colombia

IntroductionSARS-CoV-2 infection is an emerging disease that represents a threat to life globally, with more than 179 million confirmed cases and 3 million deaths. In Colombia, where almost 5 million infections and approximately 127 thousand deaths have been reported, it presents a wide variety of neurological manifestations that range from mild to severe symptoms. ObjectiveThis study describes the characteristics of neurological manifestations in patients with COVID-19 in the period March–September 2020 at a tertiary hospital in Bogota. MethodsWe performed a cross-sectional descriptive study. We selected patients by non-probability sampling, including all patients attended by the neurology service at our hospital. We included all patients with infection confirmed by RT-PCR test and neurological disease confirmed by tomography, study of cerebrospinal fluid, and clinical manifestations reported in the medical history. We excluded epileptic patients who presented seizures as the only clinical manifestation. ResultsIn a total of 58 patients, the mean age was 58 years, with 60.3% of patients being men; 65.5% were alert at admission. The main neurological symptom was brain ischaemia, in 36.2%, followed by seizures, in 25.9%. Arterial hypertension was observed in 58.6%. We observed no alterations in the cerebrospinal fluid; the mean hospital stay was 35 days, and 41.4% of patients died. ConclusionsSARS-CoV-2 infection not only affects the respiratory system, but can also cause a range of neurological manifestations ranging from mild symptoms such as headache, dysgeusia, and anosmia to severe complications such as seizures, brain ischaemia/haemorrhage, encephalopathy, or death.

Congenital heart defects and umbilical cord abnormalities, an unknown association?

Few studies exist that research the association between umbilical cord characteristics with cardiac malformations. In this study, we describe a population of newborns with congenital heart defects (CHD) and the frequency of presentation of umbilical cord (UC) alterations, based upon the hypothesis that the continuity of the cardio-placental circuit can be affected by similar noxas during early development. We carried out a descriptive study at a hospital in Bogota based on clinical records from newborns with congenital heart disease with placental and UC pathology results. Group analyses were done according to the major categories of the ICD-10. We analyzed 122 cases and found that the most frequent alterations where hypercoiling (27.9%) and abnormal UC insertion (16.4%). Additionally, in almost every group of CHD, more than 65%of patients had some type of cord alteration. We discovered a high frequency of UC alterations in patients with CHD. This outcome suggests that a possible association exists between the two phenomena, further research is needed.

Clinical and Epidemiological Profile of Patients with Invasive Aspergillosis from a Fourth Level Hospital in Bogota, Colombia: A Retrospective Study.

Invasive aspergillosis (IA) is a severe mycosis caused by Aspergillus species. The infection mainly affects immunocompromised patients with a significant clinical burden. This study aimed to determine the clinical and epidemiological characteristics of patients diagnosed with IA in a fourth level hospital in Colombia, as these data are scarce in the country. A retrospective, observational study, from a single center was conducted with 34 male and 32 female patients, between 1 month- and 90-year-old, diagnosed with proven (18.2%), probable (74.2%) and possible (7.6%) IA, during a 21-year period. The most frequent underlying conditions for IA were chemotherapy (39.4%) and corticosteroid use (34.8%). The lung was the most common affected organ (92.4%). Computed tomography (CT) imaging findings were mainly nodules (57.6%) and consolidation (31.8%). A low positive correlation was found between serum galactomannan and hospitalization length. Aspergillus fumigatus prevailed (73.3%) in sputum and bronchoalveolar lavage cultures. Most patients were hospitalized in general wards (63.6%) and treated with voriconazole (80.3%). Mortality rate was 15.2%. Common risk factors for IA were identified in the Colombian cohort, including medications and underlying diseases. However, their frequency differs from other countries, reinforcing the idea that local surveillance is essential and at-risk patients should be carefully monitored.

805. Outbreak of Ralstonia pickettii Bacteremia Caused by Contaminated Hydromorphone in a Universitary Hospital in Bogota, Colombia

Background Ralstonia pickettii are aerobic non fermenter gram negative bacilli isolated in water and soil. It is related to nosocomial infection outbreaks and considered an opportunistic pathogen. There have been outbreaks reports due to contaminated water systems and sterile drug solutions which mainly occurs during manufacturing. We present the report of an outbreak of R. pickettii bacteremia secondary to a contamination of hydromorphone vials.MethodsIn February 2021 an outbreak of R. pickettii bacteremia was identified. All isolates were from blood cultures with slow growth, thus indicating the culturing of liquid inputs, intravenous administration solutions and commonly used drugs among patients including hydromorphone. Mass spectrometry (MALDI-TOF) was used for the identification and automated microdilution to determine sensitivity to antimicrobials of the isolates and clonality analysis of genetic relationships was carried out using the DICE coefficient, UPGMA algorithm ResultsDuring the outbreak, 19 patients with R. pickettii bacteremia were identified The global attack rate was 1,9%. 11/19 (58%) were women and 13/19 (68%) of the isolations were from inward patients and 6/19 (32%) were from intensive care unit. Factors that could contribute to the appearance of the outbreak were underlying pathology, 2 patients with a diagnosis of diabetes mellitus, 10 patients with a diagnosis of arterial hypertension, 5 patients with obesity, 6 patients with heart disease, additionally 7 patients with a diagnosis of SARS COV 2 and 6 patients with the use of corticosteroids. The global attack rate was 1,9% and mortality was 31.5% (6 patients). R. pickettii was identified from two batches of hydromorphone by MALDI-TOF and the clonality study concluded that the isolates analyzed, were clonal with a 100% similarity. The associated mortality rate was 5/29 (26.3%). ConclusionWe confirmed an outbreak of R. pickettii due to the contamination of two hydromorphone badges in Colombia. It is crucial to acknowledge the importance of infection control and surveillance during the COVID-19 pandemic as well as maintaining adequate quality control of medication production in order to avoid presenting this kind of outbreaks.

Management of complex wounds treatment with a hydrofiber dressing in a public hospital in Bogota (Colombia)

Objective. To evaluate the efficacy of the use of a last generation hydrofiber dressing with silver, for the treatment of complex wounds that are difficult to heal.Materials and research methods. A prospective observational case-follow-up study was carried out, which included patients with acute or chronic wounds that were difficult to heal, treated in the plastic surgery service of a public hospital in Bogota-Colombia, who underwent healing with hydrofiber dressings reinforced, with silver ions, benzethonium chloride and EDTA (Aquacel Agplus®, ConvaTec). The wound was monitored, evaluating infection control, exudate and biofilm, as well as the number of required dressings and the time required for the complete closure of the wound.Research results. A total of 55 patients were included, with a median age of 44 years. In all cases, a follow-up was carried out until the definitive closure of the wound. At the end of the study, it was observed that, in 35 (63.6 %) patients, the wounds evolved to complete closure by second intention in an average of 59.3 days, requiring 12.5 dressings. 20 (36.4 %) patients had adequate wound bed preparation for definitive surgical coverage with grafts, flaps or dermal substitutes, in an average of 31.4 days, requiring 6.5 dressings on average.33 (60.0 %) wounds were infected and adequate infection control was achieved on average with 5 dressings. A decrease in the direct and indirect signs of biofilm was achieved after 6 dressings.Conclusion. The results show that the dressing studied is effective to control exudate, infection and biofilm, as well as to prepare the bed for a definitive surgical coverage.

Complicaciones intrahospitalarias en una unidad geriátrica de agudos

ResumenIntroducción.Las complicaciones hospitalarias ocurren con gran frecuencia en personas mayores de 65 años hospitalizadas y conllevan peores resultados clínicos. Son pocos los estudios sobre los factores asociados con las complicaciones hospitalarias en la atención de adultos mayores.Objetivo.Evaluar los factores asociados con las complicaciones hospitalarias en una unidad geriátrica de agudos en Bogotá, Colombia.Materiales y métodos.Se hizo un estudio observacional analítico basado en una cohorte retrospectiva que incluyó 1.657 pacientes mayores de 65 años atendidos en una unidad de hospitalización en Bogotá, Colombia. La variable dependiente fueron las complicaciones hospitalarias y, las independientes, la dependencia funcional, la demencia, el estado nutricional, el soporte social, las comorbilidades y la polifarmacia. Se utilizó el modelo de regresión lineal de Poisson para determinar las variables asociadas.Resultados.En el análisis bivariado se encontró que la dependencia funcional (razón de prevalencia, RP=2,092; p≤0,001) y la malnutrición (RP=2,850; p≤0,001) eran factores asociados con una mayor tasa de complicaciones hospitalarias. En el análisis multivariado aparecían como factores independientes (dependencia funcional: RP=1,931 y p=0,003; malnutrición: RP=2,502 y p=0,002).Conclusión.El hacer una evaluación integral que permita determinar la dependencia funcional y la malnutrición en el momento de ingreso en las unidades de hospitalización, permitiría predecir complicaciones hospitalarias.
