Unveiling the truth: is COVID-19 reimbursement in Colombia a flawed design? A cost-of-illness analysis for moderate, severe and critical infections.

PURPOSE: This study examines the financial impact of the COVID-19 pandemic on the Colombian Health System, focusing on the adequacy of reimbursement rates for inpatient stays. The study, based on a cost of illness analysis, aims to evaluate the effectiveness of the reimbursement scheme and identify potential economic losses within the health system. PATIENTS AND METHODS: The study protocol outlines the inclusion criteria for patients >18 years with confirmed COVID-19 infection and moderate to critical disease. Patients hospitalised between June 2020 and June 2021 for at least 24 hours were included. Exclusion criteria involved pregnant patients and those initially hospitalised for non-COVID-19. RESULTS: The study included 781 patients contributing to 790 hospitalisations. Demographic and clinical characteristics were analysed, with critical illness being the most prevalent category (61%). The overall mortality rate was 20.3%, primarily observed in critically ill patients. In the general ward for moderate cases, the reimbursement rate saw a substantial increase from US$3237 in 2020 to US$6760 in 2021, surpassing median resource utilisation. However, for severe cases in the intermediate care unit, reimbursement rates decreased, indicating potential insufficiency in covering costs. In the intensive care unit for critical cases, despite improved reimbursement rates, median resource utilisation still exceeds the 2021 rate, suggesting financial insufficiency in reimbursement rates. CONCLUSION: Our study underscores the inadequacies of the previous reimbursement system in addressing the varying resource utilisation and costs associated with COVID-19 inpatient care. Our analysis reveals substantial discrepancies between estimated costs and actual resource utilisation, particularly for severe and critical cases. We advocate for government flexibility in revising reimbursement baskets, supported by pilot studies to assess effectiveness. The use of real-world evidence forms a crucial basis for informed adjustments to reimbursement levels in preparation for future pandemics. This proactive approach ensures alignment between reimbursement policies and the actual costs associated.

Use of venovenous (VV) extracorporeal membrane oxygenation (ECMO) in near-fatal asthma: a case series.

Introduction: Status asthmaticus (SA) and near-fatal asthma (NFA) are life-threatening conditions that continue to present a management challenge for physicians. Extracorporeal Membrane Oxygenation (ECMO) has been employed as a last resort in treating these patients. Case presentation: We described six patients who were admitted to the ICU for NFA and received ECMO treatment at a high-complexity institution in Cali, Colombia, between 2015 and 2019. All patients are registered in the ELSO registry. Baseline patient characteristics, arterial blood gases (ABG), ventilatory parameters, and complications were collected as specified in the ELSO registry form. Efficacy was analyzed in terms of the improvement in respiratory acidosis, the number of ventilator-free days (VFD), and a reduction in mechanical power (MP). MP, which refers to the energy associated with the mechanical forces involved in breathing and the functioning of the respiratory system, was calculated using a mathematical formula. Safety was evaluated based on the incidence of complications. After 12 hours of ECMO, we achieved a correction of respiratory acidosis, a significant decrease in all ventilatory parameters, and a reduction in MP ranging from 52.8% to 89%. There was one mortality. Among the five surviving patients, all except one, who required a tracheostomy, had a high VFD score, with a mode of 26 days, demonstrating a reduction in ventilation time. Conclusion: Further randomized controlled trials are needed to fully understand the efficacy and safety profiles of ECMO in SA/NFA. MP is being widely used to achieve safer ventilation, and although more data is required, it appears to be a promising option for evaluating the risk of developing VILI and the success of the therapy.

Telemedicine for the management of diabetic patients in a high-complexity Latin American hospital.

BACKGROUND: Noncommunicable diseases such as diabetes mellitus (DM) have gained attention worldwide. Latin America experienced a rise in rates of DM. During the COVID-19 pandemic, a telemedicine program was implemented in a quaternary care academic complex in Latin America to continue the follow-up of patients with diabetes. OBJECTIVE: The aim of this study is to describe the clinical experience of DM patient management through telemedicine and the HbA1c behavior of patients followed-up through this modality. MATERIALS AND METHODS: We conducted a retrospective cohort study including all patients with type 1 or 2 diabetes who were treated via telemedicine from March to December 2020. A Wilcoxon statistical test was used to compare the changes in glycosylated hemoglobin between the first teleconsultation and after 6 months of telemedicine follow-up. RESULTS: A total of 663 patients were included, 17.65% (117) of whom had type 1 diabetes and 82.35% (546) of whom had type 2 diabetes. Patients with both types of diabetes, presented with stable HbA1c values regardless of the length of follow-up. CONCLUSION: The use of telemedicine can be a helpful tool for both patients and health care providers to support the continuity of care to maintain acceptable control levels within glycemic control goals.

Clinical outcomes in patients with solid tumors living in rural and urban areas followed via telemedicine: experience in a highly complex latin american hospital.

BACKGROUND: Difficulties in cancer services access increase the burden of disease and mortality in rural areas, and telehealth can be a useful tool to address these inequalities. OBJECTIVE: We aimed to describe the outcomes of patients in rural and urban areas with solid tumors managed by oncologists through telemedicine. METHODS: We conducted a retrospective cohort study of patients with solid tumors from March to December 2020. A total of 1270 subjects with solid tumors were included, 704 living in urban areas and 566 in rural areas. RESULTS: The most frequent tumors were breast (51.8%) and prostate (12.4%). The trend of telemedicine care was similar for both populations; in-person care was more frequent in the urban population. There were no differences in referral to the emergency room, need for hospitalization, and mortality for both groups. CONCLUSION: Telemedicine is a care modality that reduces barriers in the care of patients with solid tumors, evidencing similar outcomes regardless of living in rural or urban areas.

Primary thymus tumors: retrospective case analysis at a reference center in Latin America, 2011-2019.

BACKGROUND: Thymic tumors are unusual neoplasms, representing 0.2 to 1.5% of tumors in humans, but correspond to 20% of mediastinal tumors and 50% of those that occur in the anterior mediastinum. They tend to appear around the fourth and fifth decades of life without gender predilection. Up to 30% of patients are asymptomatic, therefore many are incidentally diagnosed. Radical thymectomy is the treatment of choice with high survival rates when detected in the early stages. METHODS: This was a retrospective descriptive study, including 18 adult patients' diagnosis of thymic neoplasm, who were managed with surgical resection from 2011 to 2019. Information about demographics, clinical characteristics, imaging findings, surgical and medical management, plus histological findings was obtained and reported. RESULTS: 18 patients with thymic tumors were included, of which specific histologic studies reveled thymomas, carcinomas, neuroendocrine tumors, thymolipoma and thymic cyst. Mean age was 52.7 years, with a predominance of male population. The main symptom was dyspnea, followed by cough and chest pain. Paraneoplastic syndromes such as myasthenia gravis, aplastic anemia and Cushing syndrome were reported. 89% of cases were treated by radical thymectomy alone, while only 2 cases required chemotherapy and radiotherapy. There were no surgical complications. Mean hospital stay length was 11. 9 days, with only 1 mortality during hospital admission. 5-year survival rate was 81%. CONCLUSIONS: The treatment of choice is radical thymectomy, which has been shown to positively impact patient mortality. Early detection is key to improve patient outcomes.

Aspirin desensitization in NSAID-exacerbated respiratory disease and its outcomes in the clinical course of asthma: A systematic review of the literature and meta-analysis.

BACKGROUND: Nonsteroidal anti-inflammatory drug-exacerbated respiratory disease (NERD) might benefit from aspirin desensitization (AD) as an alternative treatment to standard care. However, there is conflicting evidence regarding its role in bronchial symptoms and asthma exacerbations. OBJECTIVE: To analyze the clinical effects of AD in terms of lung function, systemic and inhaled steroid use, the frequency of acute asthma exacerbations, and adverse effects in patients with NERD and asthma. METHODOLOGY: We identified randomized clinical trials (RCTs) from PubMed, EMBASE, SCOPUS, and EBSCO. We also searched the RCT references for additional studies. Studies comparing AD to placebo in patients with a previous history of pulmonary symptoms triggered by ASA or other NSAIDs or with a positive provocation test to ASA were included. PRIMARY RESULTS: Five studies with 210 participants with NERD were included in this review. The study duration ranged from 3 to 6 months. Overall, the risk of bias across the included RCTs was low. We identified 3 studies evaluating lung function, 2 of which reported a significant improvement in FEV1 in the AD group after 6 months, while the other reported no difference among the treatments. Due to high heterogeneity, we did not pool the results. The remaining primary outcomes were reported only in a single study each, hindering their interpretation. Secondary outcomes revealed reduced symptom and medication scores in patients with AD. CONCLUSIONS: Due to the small number of studies included in this systematic review, conclusions should be made with caution. AD shows a trend towards improving lung function (FEV1) following 6 months of treatment, although no conclusions can be made regarding the use of corticosteroids or the frequency of acute exacerbations. AD appears to reduce both symptom and medication scores. Additional RCTs are needed to fully assess the efficacy of AD in reducing bronchial symptoms in patients with NERD.

Inhaled tobramycin for chronic infection with pseudomonas aeruginosa in non-cystic fibrosis bronchiectasis: A systematic review and meta-analysis.

INTRODUCTION: Non-cystic fibrosis bronchiectasis (NCFBE) is a chronic and progressive disease characterized by the permanent destruction of small and mid-sized airways. Many patients are chronically colonized by Pseudomona aueruginosa, for which oral antibiotics are given. Evidence to support the use of inhaled antibiotics is contradictory. OBJECTIVE: To describe the clinical effects of inhaled Tobramycin in P. aeruginosa density in sputum and eradication, lung function, bacterial resistance, and exacerbations requiring hospital admission, in the context of patients with NCFBE colonized by P. aeruginosa. METHODS: We included RCTs comparing inhaled tobramycin to other antibiotics and placebo in patients with NCFBE. MAIN FINDINGS: 5 studies with 211 participants were included. 2 studies reported a significant but transitory decrease in P. aeruginosa density in sputum as compared to placebo. There was a small difference in the eradication of P. aeruginosa among groups, although with very wide confidence intervals. Tobramycin reduced the rate of hospital admissions but no frequency of exacerbations. There was no evidence of an increased rate of bacterial resistance but was associated to respiratory adverse effects. CONCLUSIONS: Evidence is not robust enough to confirm a benefit of inhaled Tobramycin in reducing P. aeruginosa sputum density or eradication. There was a high attrition rate, in part due to respiratory adverse events after drug administration, which affects interpretation of the data and raises concerns about the tolerability of the drug. Further network meta-analysis should be done to compare the efficacy and safety of different inhaled antibiotics.

Sternal cavernous hemangioma and reconstruction of the anterior chest wall: a case report.

BACKGROUND: The sternum is considered an unusual tumor site, corresponding to 15% of all thoracic wall tumors. Primary sternal tumors are even rarer and most commonly malignant. We present the case of a young man who consulted with a painful sternal mass, which after its resection is confirmed to be a cavernous hemangioma. CASE PRESENTATION: A 39-year-old man, with unremarkable medical history besides a 2-year-long sternal pain, non-irradiated, which worsens over the last few months and is accompanied by the appearance of a sternal palpable mass. On physical exam, there was a bulging of the sternal manubrium, with no inflammatory changes. Thoracic CT scan shows an expansive and lytic lesion of the sternum, compromising the manubrium and extending to the third sternocostal joint, without intrathoracic compromise nor cleavage plane with mediastinal vascular structures. The patient is taken to resection of the mass and sternal reconstruction using prosthetic material and pectoral and fasciocutaneous muscular flaps. Histopathological findings: cavernous hemangioma with negative borders and no other malignant findings. CONCLUSIONS: Sternal hemangiomas can cause defects in the bone structure and show an expansive growth, challenging the differentiation between a benign or malignant lesion. Therefore, they should be considered malignant until shown otherwise. Management involves radical surgery with curative purposes and posterior reconstruction to improve quality of life, as shown with our patient.

Acute respiratory failure as initial manifestation of conventional osteosarcoma rich in giant cells: a case report.

BACKGROUND: Osteosarcoma is a malignant tumor of the bone. The giant cell-rich osteosarcoma (GCRO) is a rare histological variant of the conventional osteosarcoma, accounting for 3% of all osteosarcomas. It has a variable clinical presentation, ranging from asymptomatic to multiple pathological fractures, mainly involving long bones, and less frequently the axial skeleton and soft tissues. CASE PRESENTATION: We present the case of a 25-year-old Hispanic woman, previously healthy, with a 1-month history of dyspnea on exertion, intermittent dry cough, hyporexia, and intermittent unquantified fever. She presented to the emergency department with a sudden increase in dyspnea during which she quickly entered ventilatory failure and cardiorespiratory arrest with pulseless electrical activity. Resuscitation maneuvers and orotracheal intubation were initiated, but effective ventilation was not achieved despite intubation and she was transferred to the intensive care unit of our institution. The chest radiograph showed a mediastinal mass that occluded and displaced the airway. The chest tomography showed a large mediastinal mass that involved the pleura and vertebral bodies. A thoracoscopic biopsy was performed that documented a conventional giant cell-rich osteosarcoma. The patient was considered to be inoperable due to the size and extent of the tumor and subsequently died. CONCLUSIONS: The giant cell-rich osteosarcoma is a very rare histological variant of conventional osteosarcoma. Few cases of this type of osteosarcoma originating from the spine have been reported in the literature, and to our knowledge none of the reported cases included invasion to the chest cavity with airway compression and fatal acute respiratory failure that was present our case. Radiological and histological features of the GCRO must be taken into account to make a prompt diagnosis.

Use of monoclonal antibodies for allergic bronchopulmonary aspergillosis in patients with asthma and cystic fibrosis: literature review.

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction (HR) mediated by antigens to Aspergillus fumigatus. It is estimated that 2-15% of patients with cystic fibrosis (CF) and between 1% and 5% of asthmatics develop ABPA, affecting approximately 4.8 million people worldwide. The goals of treatment are controlling inflammation, reducing the number of exacerbations and limiting the progression of lung damage. Systemic steroids are therefore used as the mainstay therapy, along with antifungal medications. However, many patients do not respond or develop side effects to treatment. In this scenario, biological drugs such as Omalizumab, Mepolizumab, Benralizumab and Dupilumab have been implemented in clinical practice, even though there is a lack of scientific evidence to support their use. We performed a literature review of the studies carried out which analyzed biologics for the management of ABPA in adult populations with asthma and CF. To our knowledge this is the first literature review that included all biologics. We included a total of 32 studies, all but one were descriptive studies, and the vast majority evaluated the use of Omalizumab. Biologics appeared to have more benefit for patients with ABPA and asthma than CF, specifically at decreasing the frequency of acute exacerbations and by having a steroid-sparing effect. Although a decrease in serum IgE level is considered a measure of therapy success, values may not decline as expected in the context of a significant clinical improvement, highlighting the importance of measuring patient-oriented outcomes. As evidence comes mainly from case series and case reports, randomized controlled trials are needed to evaluate further the safety and efficacy of biologics in ABPA.The reviews of this paper are available via the supplemental material section.

Thoracic Computed Tomography Scan and Bronchoscopy Appearance of Mounier-Kuhn Syndrome: A Case Report.

Mounier-Kuhn syndrome (MKS) is a rare congenital disease with an autosomal recessive inheritance pattern, characterized by an enlargement of the trachea and bronchi. MKS is secondary to a thinning of the muscular mucosa and atrophy of the longitudinal muscle and elastic fibers of the tracheobronchial tree. As a consequence, tracheal diverticulosis and dilatations in the posterior membranous wall appear, along with bronchiectasis that tend to be cystic in appearance. Overall, there is an impairment of mucocilliary clearance, with an ineffective cough, which predisposes the patient to recurrent lower respiratory tract infections. Clinical manifestations vary from asymptomatic to respiratory failure and death, most patients being diagnosed between the third and fourth decades of life. It is an often undiagnosed disease, with a diagnostic algorithm that includes the use of radiological techniques, alone or in combination with bronchoscopy. Specific diagnostic criteria have been developed, based on patients' tracheal and main bronchi diameter on chest X-ray and thoracic computed tomography scan. We present the case of a 45-year-old African American man who presented with a history of multiples episodes of pneumonia that required management in the intensive care unit, on whom MKS was diagnosed.

Ossifying Lipoma in Costal Arches That Suggest Extensive Pulmonary Involvement: Case Report.

BACKGROUND: Lipomas are the most common benign soft tissue tumors in the general population. These lesions can appear on any part of the body and usually develop in the subcutaneous superficial tissue. Lipomas that show ossifying changes are very rare, representing less than 1% of the reported lipomas. They usually manifest as hard nodular lesions in the head and neck, the extremities, the sternoclavicular region, and the subcutaneous tissue in general; they are rare in the costal arches. CASE PRESENTATION: We report the case of a patient with a history of multiple diseases and 2 tumor-like lesions with internal lytic areas detected in the fourth right costal arch and in the eighth left costal arc; we describe his clinical manifestations, radiological and laboratory findings as well as the pathological results and outcome. CONCLUSIONS: Ossifying lipomas are rare benign tumors with asymptomatic clinical presentation. It is important to perform an adequate radiological differentiation from other more aggressive lesions such as liposarcomas.

Tracheobronchopathia Osteochondroplastica-Clinical, Radiological, and Endoscopic Correlation: Case Series and Literature Review.

Tracheobronchopathia osteochondroplastica (TO) is a rare idiopathic and benign disease that is often underdiagnosed. TO is characterized by multiple submucosal cartilaginous and osseous tracheobronchial nodules that spare the posterior wall. It usually affects the elderly, developing when the person is around 60 years old without gender preference and has a reported incidence of 0.11%. TO can be symptomatic and should be considered in patients with chronic cough, dyspnea, and recurrent pulmonary infections. Diagnosis is usually incidental by computed tomography or bronchoscopy, the latter being the gold standard diagnostic test for TO. Many thoracic imagers are not well acquainted with TO; thus, these patients are often underdiagnosed or misdiagnosed. We came across 5 patients in our institution who were incidentally diagnosed with TO, inspiring us to review the available literature on this disease. A total of 33 patients diagnosed with TO between 2009 and 2019 were identified by our retrospective review. Clinical and imaging data were collected on these patients. We also included the clinical, radiological, and endoscopic data of our 5 cases. TO should be considered in patients with chronic cough, dyspnea, and recurrent pulmonary infections. Our experience is that both computed tomography and bronchoscopy can be used to make a reliable diagnosis. It is crucial for physicians, especially radiologists and pulmonologists, to be aware of the existence of TO in order to ensure proper diagnosis.

Video-Assisted Thoracoscopic Lung Biopsy in Critically Ill Patients With Hematologic Malignancy and Acute Respiratory Distress Syndrome: A Case Series Report.

Pulmonary complications are prevalent among patients with hematologic malignancies, who are at high risk of developing acute respiratory distress syndrome (ARDS). Although diffuse alveolar damage is considered the diagnostic hallmark of ARDS, there are plenty of other non-diffuse alveolar damage etiologies that can mimic ARDS and benefit from a specific therapy, therefore correcting the underlying cause. When the etiology remains unclarified despite noninvasive procedures, a surgical lung biopsy (either open via thoracotomy or video-assisted thoracoscopic surgery [VATS]) may be warranted. However, the role of surgical lung biopsy has not been extensively studied in patients with hematologic malignancy and ARDS and so doubt exists about the risk-benefit relationship of such procedures. In this article, we report a series of 8 critically ill patients with hematologic malignancies and ARDS, who underwent VATS lung biopsy, in a specialized institution in Cali, Colombia, from 2015 to 2019, with special emphasis on its diagnostic yield, modifications in treatment protocol, and safety. VATS lung biopsy is a minimally invasive procedure that appears to be a relatively safe with few postoperative complications and minimal perioperative mortality. It has a high diagnostic yield, resulting in a modification of treatment in a nondepreciable percentage of patients. However, this subset of patients was critically ill, with a high risk of mortality, and the lung biopsy did not appear to affect in this aspect. Future randomized controlled trials are needed to further clarify this topic.

Right main bronchus rupture associated with blunt chest trauma: a case report.

BACKGROUND: Tracheobronchial injury is one of the least common injuries in the scenario of blunt chest trauma. However, around 81% of patients with airway injury die immediately or before arriving at the emergency department due to tension pneumothorax. It presents with non-specific signs and symptoms challenging prompt diagnosis. CASE PRESENTATION: A 15-year-old adolescent who was riding a bicycle suffered an accident when he fell down a cliff, approximately 5 m deep. Upon admission to the emergency department, he presented with signs of respiratory distress. The airway was secured and a thoracoabdominal angiography was performed. The image reported pneumomediastinum, a small right pneumothorax, areas of pulmonary contusion, and an image of loss of continuity in the anterior superior wall of the right main bronchus highly suggestive of bronchial rupture. The bronchial lesion was then confirmed by fiberoptic bronchoscopy. Taking into account the patient's characteristics, conservative management was chosen, and the patient was transferred to the intensive care unit (ICU) where protective tracheal intubation was performed. CONCLUSIONS: A delay in diagnosis increases the rate of complications, mainly infectious complications and the formation of granulation tissue that could potentially obstruct the airway, impacting the patient's outcome. The first step in the management of these patients is securing the airway, which should be done immediately. The gold standard for the diagnosis and characterization of airway injuries is bronchoscopy as it is the most effective tool to assess topography, extent, and depth of the lesion.
