Clinical inertia in newly diagnosed type 2 diabetes mellitus among patients attending selected healthcare institutions in Colombia.

BACKGROUND: The burden of disease of diabetes in Colombia have increased in the last decades. Secondary prevention is crucial for diabetes control. Many patients already treated remain with poor glycemic control and without timely and appropriate treatment intensification. This has been called in the literature as Clinical Inertia. Updated information regarding clinical inertia based on the Colombian diabetes treatment guidelines is needed. OBJECTIVE: To measure the prevalence of clinical inertia in newly diagnosed Type 2 Diabetes Mellitus (T2DM) patients in healthcare institutions in Colombia, based on the recommendations of the current official guidelines. METHODS: An observational and retrospective cohort study based on databases of two Health Medical Organizations (HMOs) in Colombia (one from subsidized regimen and one from contributory regimen) was conducted. Descriptive analysis was performed to summarize demographic and clinical information. Chi-square tests were used to assess associations between variables of interest. RESULTS: A total of 616 patients with T2DM (308 for each regimen) were included. Median age was 61 years. Overall clinical inertia was 93.5% (87.0% in contributory regimen and 100% in subsidized regimen). Patients with Hb1Ac ≥ 8% in the subsidized regimen were more likely to receive monotherapy than patients in the contributory regimen (OR 2.33; 95% CI 1.41-3.86). CONCLUSIONS: In this study, the prevalence of overall clinical inertia was higher in the subsidized regime than in the contributory regime (100% vs 87%). Great efforts have been made to equalize the coverage between the two systems, but this finding is worrisome with respect to the difference in quality of the health care provided to these two populations. This information may help payers and clinicians to streamline strategies for reducing clinical inertia and improve patient outcomes.

Direct Medical Costs and Healthcare Resource Utilization of Treating Patients With Two Clinical Subtypes of Axial Spondyloarthritis in Colombia.

OBJECTIVES: This study aimed to calculate the healthcare resource utilization and direct medical costs in patients with 2 subtypes of axial spondyloarthritis (axSpA) in a rheumatic care center in Colombia. METHODS: This is a retrospective cost-of-illness study. Patients with at least 1 medical consultation associated with an axSpA diagnosis between October 2018 and October 2019 were identified. Patients were classified as having radiographic (r-axSpA) or nonradiographic axSpA (nr-axSpA). Direct medical costs were calculated in Colombian pesos and expressed in American dollars using an exchange rate of 3263 Colombian pesos = 1 US dollar ($). Predictors of total direct costs were identified using a generalized linear model with gamma distribution and log-link. RESULTS: A total of 162 patients with a mean age of 49.6 years (± 13.7) were included in the study. Among these, 147 (90.7%) were considered as having r-axSpA and 15 (9.3%) nr-axSpA, with mean costs of $6600 (± 6203) and $843 (± 1135), respectively (P < .001). The total direct mean cost was calculated at $6067 (± 6144) per patient. Medication costs were the main driver of total costs (97.6%, $5921), with biologic disease-modifying antirheumatic drugs accounting for nearly 92.0% ($5582) of these costs. Rheumatologist (100%) and physiatrist (64.2%) visits were the most frequently used medical service. CONCLUSIONS: The economic burden associated with axSpA in the Colombian setting is substantial. There is a significant difference in direct medical costs between the r-axSpA and the nr-axSpA. Health policies aimed at the comprehensive management of nr-axSpA would have an important role in the reduction of the associated direct medical costs.

Centers of Excellence Implementation for Treating Rheumatoid Arthritis in Colombia: A Cost-Analysis.

BACKGROUND: Health systems need to optimize the use of resources, especially in high-cost diseases as rheumatoid arthritis (RA). We aimed to evaluate the efficiency of using centers of excellence (CoE) as a strategy for improving RA treatment in Colombia. METHODS: A cost description analysis was carried out using the standard costing technique. We estimated the costs of medical consultations, laboratories, images, and medications for RA. Categories of care standards stratified by severity were defined using the disease activity score in 28 joints (DAS28). We evaluated the impact, in terms of costs (US dollars), for providing RA clinical care for a previously described cohort using the CoE approach. Statistical analyses were performed in Microsoft Excel®, and R. RESULTS: Expenditure on therapeutic drugs increases as the severity of RA increases. Drugs represent 53.6% of the total cost for the low disease activity (LDA) stage, 75.2% for moderate disease activity (MDA), 88.5% for severe disease activity (SDA) and 97% for SDA with biologic treatment (SDA+Biologic). Treating 968 patients would cost US$612,639 (US$487,978-1,220,160) at baseline, per year. After a year of follow-up at the CoE, treating the same patients would cost US$388,765 (US$321,710-708,476), which implies potential cost-savings of up to US$223,874 per year. CONCLUSION: The strategy of providing clinical care for RA through CoE can save US$231.3 per patient-per year. The results of our study show that CoE could greatly impact the public policies dealing with treatment of RA in Colombia. Applying the CoE model in our country would both improve health outcomes, as well as being more efficient in terms of costs.

Frequency of Health Care Resource Utilization and Direct Medical Costs Associated with Psoriatic Arthritis in a Rheumatic Care Center in Colombia.

OBJECTIVE: To estimate the frequency of health care resource utilization and direct medical costs associated with Psoriatic Arthritis (PsA) in a rheumatic care center in Colombia. METHODS: A retrospective prevalence-based cost of illness study under the Colombian health care system perspective was conducted. We analyzed the frequency of health care resource utilization and estimated direct medical costs using anonymized medical records of adult patients (≥18 years) diagnosed with PsA at a rheumatology care center in Bogotá, Colombia. Patients were required to have at least one medical visit linked to a PsA diagnosis (ICD-10 L40.5) between October 2018 and October 2019 and a previous diagnose by the CASPAR criteria. Data on hospitalization episodes was not available. Direct medical costs were estimated in Colombian pesos (COP) and reported in US dollars (USD) using an exchange rate of 1USD = 3263.4 COP. A multivariate generalized linear model was used for identifying potential cost predictors. RESULTS: A sample of 83 patients was obtained. Of these, 54.2% were women and had a mean (SD) age of 58.7 (12) years at baseline. On average, they had 2.2 and 3.8 medical visits to the dermatologist and rheumatologist in the study period. The total direct medical cost was estimated at 410,985 US Dollars. Medical visits, therapies, laboratory and imaging represented 3.2% of total expenses and medications the remaining 96.8%. Patients receiving conventional DMARDs (cDMARDs) had an associated mean cost of 1020.1 USD (CI 701.4-1338.8) in a year. Among patients treated with cDMARDs and biological DMARDs (bDMARDs) the mean cost increase to 8113.9 USD (SD 5182.0-95% CI 6575.1-9652.8). CONCLUSION: A patient under biological therapy can increase their annual cost by 7.9 times the cost of a patient in conventional therapy. This provided updated knowledge on the direct medical costs, from the provision of a rheumatic care center service, to support epidemiologic or pharmacovigilance models.

Economic Cost of Severe Acute Respiratory Infection Associated to Influenza in Colombian Children: A Single Setting Analysis.

BACKGROUND: Influenza is considered a leading public health problem because its large economic burden of disease worldwide, especially in low-and middle-income countries, such as Colombia. OBJECTIVE: We aimed to estimate the economic costs of influenza-confirmed patients in a pediatric hospital in Cartagena, Colombia. METHODS: We conducted a retrospective costing analysis. We estimated the direct (direct medical and out-of-pocket expenditures) and indirect costs for influenza-confirmed severe acute respiratory infection cases from a societal perspective. Total economic costs were calculated adding direct medical costs, out-of-pocket expenditures, and indirect costs owing to loss of productivity of caregivers. Mean, median, 95% confidence interval (95% CI) and interquartile range (IQR) of costs were measured. All costs are reported in USD ($1.00 = COP$2000.7) RESULTS: Forty-four cases were included in the analysis: 30 had influenza B, 10 influenza A and B, and 4 influenza AH1N1. Thirty patients were hospitalized in the general ward, 14 went to the intensive care unit. The average duration of stay was ∼9 days (95% CI, 6.3-11.5). The median direct medical cost for hospitalized case in general ward was $743.50 (IQR $590.20-$1404.60) and in intensive care unit $4669.80 (IQR $1614.60-$7801.50). The economic cost per hospitalized case was $1826.10 (IQR $1343.30-$2376.50); direct medical costs represented 93.8% of this cost. The median indirect cost was $82.10 (IQR $41.10-$133.40) and the median out-of-pocket expenditure per case was $45.70 (IQR $29.50-$64.90). CONCLUSIONS: Severe acute respiratory infection is an important source of economic burden for the health system, families, and society in Colombia. Seasonal influenza vaccination should be strengthened to prevent more cases and save economic resources.

Carga económica de la enfermedad renal crónica en Colombia, 2015-2016 / Economic burden of Chonic Kidney Disease in Colombia, 2015-2016

RESUMEN Objetivo: Estimar la carga económica asociada a la enfermedad renal crónica (ERC) en Colombia, para el periodo 2015-2016. Materiales y métodos: Se estimó la carga económica de la ERC en Colombia a partir de datos de terceros pagadores. Se realizó un costeo de los estadios de la ERC mediante la técnica de macro-costeo o top-down, con el fin de conocer el impacto económico de cada estadio en la carga global de la enfermedad. Se construyó un modelo de Markov que simulara la historia natural de la enfermedad. Se utilizó una tasa de descuento del 5% y ciclos anuales. A cada estado de la ERC se le asignó un costo relacionado con la atención, con lo cual se obtuvo un estimado del costo y de la carga de enfermedad de todos los pacientes con ERC. Resultados: Al final de los ciclos de todos los pacientes desde el estadio 1-5, incluyendo el trasplante, se estimó una carga económica que asciende a COP 10,5 billones (IC 95% COP 8,7- COP 14,4). En el escenario con tasa de descuento del 5%, la carga económica asciende a COP 7,8 billones. Conclusión: La ERC representa una alta carga económica al sistema de salud colombiano, la cual oscila entre COP 8,7 y COP 14,4 billones, que representarían entre el 1,6% y el 2,7% del producto interno bruto de Colombia en el 2015.

ABSTRACT: Objective: Estimate the economic burden due to chronic kidney disease (CKD) in Colombia, for 2015-2016. Methods: We estimated the economic burden of CKD through third payer's data. A top-down technique was used to estimate the costs related to CKD as input to estimate the economic burden of the disease. A Markov model was conducted to simulate the natural history of the disease. A 5% discount rate and annual cycles were used. Each stage of the disease had a cost associated with the disease, producing and estimation of the economic burden of all patients with CKD. Results: At the end of the modeling from stages 1-5, including transplantation, the economic burden of CKD was COP $10.5 billion (IC 95% $8.7-$14.4). In the discount rate scenario, the economic burden was COP $7.8 billons. Conclusion: CKD represents a high economic burden on the Colombian health system, which ranges from COP $ 8.7- $ 14.4 billion that would represent between 1.6% and 2.7% of Colombia's Gross Domestic Product, 2015.

Hospitalization costs due to severe acute respiratory infection (SARI) in three Central American countries / Costos de hospitalización de infección respiratoria aguda grave (IRAG) en tres países de América Central

Objective: To estimate the direct medical costs of severe acute respiratory infection (SARI) in children and adults from three Central American countries with a bottom-up costing approach. Methods: The costs of inpatients treatment were estimated through the retrospective bottom-up costing in a randomized sample of clinical records from SARI patients treated in teaching tertiary hospitals during 2009 - 2011 period. Activities incurred per patient were registered and a setting-specific cost per activity was acquired. Average cost per patient in the group of children and elderly adults was estimated for each country. In Nicaragua, only the pediatric population was included. Costs were expressed in local currency (2011), American dollars, and international dollars (2005) for country comparison. Results: The care cost per case in children in Guatemala was the cheaper (I$971.95) compared to Nicaragua (I$1,431.96) and Honduras (I$1,761.29). In adults, the treatment cost for Guatemala was the more expensive: I$4,065.00 vs. I$2,707.91 in Honduras. Conclusion: Bottom-up costing of SARI cases allowed the mean estimates per treated case that could have external validity for the target population diagnosed in hospitals with similar epidemiological profiles and level of complexity for the study countries. This information is very relevant for the decision-making.

Métodos: Los costos de pacientes hospitalizados fueron estimados a través de análisis retrospectivo en una muestra aleatoria de registros de historias clínicas de casos de IRAG tratado en hospitales universitarios durante el periodo 2009-2011. Las actividades incurridas por paciente fueron registradas y un costo especifico para cada sitio fue estimado. El costo por cada niño y adulto mayor fue estimado para cada país. En Nicaragua sólo se incluyó población pediátrica. Los costos fueron expresados en moneda local (2011), dolar americano y dolar internacional (2005). Resultados: El costo por caso en niños en Guatemala fue el más barato (I$971.95) comparado al de Nicaragua (I$1,431.96) y Honduras (I$1,761.29). En adultos, el costo de tratamiento para Guatemala fue el más costoso: I$4,065.00 vs. I$2,707.91 en Honduras. Conclusión: Los costos de tratar casos IRAG estimados a partir de costos promedios pro caso pueden tener validez externa para hospitales con perfiles epidemiologicos similares y nivel de complejidad de atención para los países del estudio. Esta información es muy relevante para la toma de decisiones.

Economic Costs of Chikungunya Virus in Colombia.

OBJECTIVE: The aim of the present study was to estimate the economic impact of chikungunya virus (CHIKV) infection in Colombia from a societal perspective. METHODS: We conducted a retrospective, bottom-up cost-of-illness study in clinically confirmed cases during the first chikungunya (CHIK) outbreak in Colombia in 2014. Direct and indirect costs were estimated per patient. Economic costs were calculated by the addition of direct costs (direct medical costs and out-of-pocket heath expenditures) and indirect cost as a result of loss of productivity. RESULTS: A total of 126 patients (67 children and 59 adults) with CHIK were included. The median of the direct medical cost in children was US$257.9 (interquartile range [IQR] 121.7-563.8), and US$66.6 (IQR 26.5-317.3) for adults. The productivity loss median expenditures reached US$81.3 (IQR 72.2-203.2) per adult patient. The median economic cost in adults as a result of CHIK was US$152.9 (IQR 101.0-539.6), of which 53.2% was a result of indirect costs. Out-of-pocket expenditures comprised 3.3% of all economic costs. CONCLUSIONS: Our study can help health decision makers to properly assess the burden of disease caused by CHIK in Colombia, an endemic tropical country. We recommend to strength the health information systems and to continue investing in public health measures to prevent CHIK.

A comprehensive care program achieves high remission rates in rheumatoid arthritis in a middle-income setting. Experience of a Center of Excellence in Colombia.

Management of rheumatoid arthritis (RA) in many Latin-American countries is impaired by fragmentation and scarce healthcare provision, resulting in obstacles to access, diagnosis, and treatment, and consequently in poor health outcomes. The aim of this study is to propose a comprehensive care program as a model to provide healthcare to RA patients receiving synthetic DMARDs in a Colombian setting by describing the model and its results. Health outcomes were prospectively collected in all patients entering the program. By protocol, patients are followed up during 24 months using a treat-to-target strategy with a patient-centered care (PCC) model, meaning that a patient should be seen by rheumatologist, physical and occupational therapist, physiatrist, nutritionist and psychologist, at least three times a year according to disease activity by DAS28. Otherwise, patients receive standard therapy. The incidence of remission and low disease activity (LDA) was calculated by periods of follow-up. A total of 968 patients entered the program from January 2015 to December 2016; 80.2% were women. At baseline, 41% of patients were in remission, 17% in LDA and 42% in MDS/SDA. At 24 months of follow-up, 66% were in remission, 18% in LDA and only 16% in MDS/SDA. Regarding DAS28, the mean at the beginning of the time analysis was 3.1 (SD 1.0) and after 24 months it was 2.4 (SD 0.7), showing a statistically significant improvement (p < 0.001). In all patients, the reduction of disease activity was 65% (95% CI, 58-71). Patients entering the PCC program benefited from a global improvement in disease activity in terms of DAS28.

Costos de tratamiento hospitalario de la infección respiratoria aguda grave en niños de Nicaragua / Cost of treatment for severe acute respiratory infection in Nicaraguan children

Objetivo: Estimar los costos de tratamiento hospitalario de la infección respiratoria aguda grave (IRAG) en niños en Nicaragua. Métodos: Se estimaron costos de tratamiento de pacientes hospitalizados a partir del microcosteo retrospectivo de una muestra aleatoria de casos ocurridos durante el periodo 2009-2011 en Nicaragua y atendidos en un hospital pediátrico universitario de alta complejidad. Se calculó una muestra aleatoria de pacientes con diagnósticos de IRAG (CIE-10), según parámetros extraídos de la literatura. En esta, se estimó el costo promedio por paciente. Los costos fueron expresados en moneda local de 2011 y dólares americanos. Resultados: El costo promedio total de atención de caso en niños fue de 314,9 US$ (intervalo de confianza [IC] 95%: 280,1-349,7 US$) y de 971,6 (655,5-1.287,8 US$) para los que requirieron UCI. El 41% de los costos en los que solo requieren hospitalización general se explican por gastos de hotelería, mientras que en los que requieren UCI el 52% es por medicamentos. Conclusión: El microcosteo de los casos incluidos de IRAG permitió estimar un valor medio por caso tratado, con sus respectivos IC y estos podrían tener validez para el total de la población atendida por estos diagnósticos en hospitales con similar perfil epidemiológico y similar nivel de complejidad en Nicaragua.

Objective: To estimate the costs of treatment for severe acute respiratory infection (SARI) in children in Nicaragua. Methods: A cost assessment was carried out on a random sample of inpatients during 2009-2011 who were treated in one pediatric universitary hospital in Nicaragua. A random sample of patients diagnosed with SARI (ICD-10) was calculated based on parameters from the literature. The average cost per patient was estimated. Costs were expressed in local currency and US dollar values in 2011. Results: The total average cost of healthcare per case was US$314.9 (confidence interval [CI]95%: 280.10-US$349.70) and US$971.60 (655.50-US$1287.80) for those requiring intensive care unit (ICU). Around 41% of the general hospitalization costs are due to the cost of the hospitalization while for those costs involving ICU care, 52% are due to drugs costs. Conclusion: We estimated an average cost per case expressed with their respective CI by microcosts analysis for SARI health care in Nicaraguan children. These costs may be representative of the population with this diagnosis in Nicaraguan hospitals with similar epidemiological profile.
