Evaluación de Tecnología Sanitaria y su impacto en políticas de tarificación y cobertura de medicamentos / Health technology assessment and its impact on pharmaceutical pricing and reimbursement policies

The article conceptualizes the pharmaceutical pricing and reimbursement policies related to financial coverage in the context of health systems. It introduces the pharmaceutical market as an imperfect one, in which appropriate regulation is required. Moreover, the basis that guide the pricing and reimbursement processes are defined and described in order to generate a categorization based on whether they are intended to assess the 'added value' and if the evaluation is based on cost-effectiveness criteria. This framework is used to review different types of these policies applied in the international context, discussing the role of the Health Technology Assessment in these processes. Finally, it briefly discusses the potential role of these types of policies in the Chilean context.

Cost-effectiveness of iso- versus low-osmolality contrast media in outpatients with high risk of contrast medium-induced nephropathy / Costo-efectividad de medios de contraste isoosmolales e hiposmolales en pacientes con alto riesgo de nefropatía inducida por medio de contraste

Introduction. Contrast media can cause acute renal failure by direct toxic effects on the tubular cells and kidney ischemia. Diabetics and hospitalized patients have a greater risk of developing contrast-induced nephropathy than the general population. Objective. The cost effectiveness of iso and low-osmolality contrast media was assessed in high risk outpatients. Materials and methods. The analysis was based on a systematic literature review comparing the nephrotoxic effects of iso- to low-osmolality contrast media. Only direct costs were considered; these were obtained from the official tariff manual. Incremental cost-effectiveness ratios, efficiency curves and acceptability curves were calculated. Univariate sensitivity analyses were performed for costs and effects, as well as probabilistic analyses. Zero and 3% discounts were applied to results. The cost-effectiveness threshold was equal to the per capita GDP per life-year gained. Results. Alternatives with Iopamidol and Iodixanol are preferable to the others, because both reduce risk of contrast-induced nephropathy and are less costly. The incremental cost-effectiveness of the Iodixanol alternative compared to the Iopamidol alternative is US$ 14,660 per additional life year gained; this is more than twice the threshold. Conclusion. The low-osmolality contrast medium, Iopamidol, appears to be cost-effective when compared with Iohexol or other low-osmolality contrast media (Iopromide, Iobitridol, Iomeprol, Iopentol and Ioxilan) in contrast-induced nephropathy, high-risk outpatients. The choice of the iso-osmolality contrast medium, Iodixanol, depends on its cost per vial and on the willingness to pay.

Introducción. Los medios de contraste pueden provocar falla renal aguda por toxicidad directa sobre las células tubulares e isquemia medular renal. Los pacientes diabéticos y los hospitalizados presentan mayor riesgo de desarrollar nefropatía inducida por medios de contraste que la población general. Objetivo. Establecer el costo-efectividad de los medios de contraste isosmolales e hiposmolales en pacientes con alto riesgo. Materiales and métodos. El análisis se basó en una revisión sistemática de la literatura científica, comparando los efectos nefrotóxicos de los medios isosmolales e hipoosmolales. Se consideraron sólo los costos directos, obtenidos del manual tarifario. Se calcularon las tasas del incremento del costo-efectividad, las curvas de eficiencia y de aceptabilidad. Se hicieron análisis univariados de sensibilidad para costos y efectos, así como probabilísticos. Se aplicaron tasas de descuento de 0 y 3 % a los resultados. Se usó como umbral de costo-efectividad por año de vida ganado, el producto interno bruto per cápita. Resultados. Las alternativas con Iopamidol y Iodixanol dominan a las demás porque reducen el riesgo de nefropatía inducida por contraste a un menor costo. La razón del incremento del costo-efectividad del iodixanol comparado con el iopamidol es de US$ 14.660 por año de vida ganado que más que duplica el umbral. Conclusión. El medio de baja osmolalidad, iopamidol, parece ser costo-efectivo comparado con iohexol u otros medios hiposmolares (iopromide, iobitridol, iomeprol, iopentol y ioxilan), en pacientes con alto riesgo de nefropatía inducida por contraste. La elección del medio hiposmolar, depende de la disponibilidad a pagar o del costo por ampolleta.

Costo-efectividad de la radiografía de tórax en lactantes con sospecha clínica de bronquiolitis viral en Colombia / Cost-effectiveness of chest x-rays in infants with clinically suspected viral bronchiolitis in Colombia

OBJETIVO: Estimar el costo-efectividad de no realizar radiografía de tórax a ningún lactante con sospecha clínica de bronquiolitis viral versus realizarla en todos estos pacientes de manera rutinaria, que es la práctica más utilizada hoy en Colombia. MÉTODOS: Se realizó un estudio de costo-efectividad en el que se compararon las estrategias consistentes en tomar radiografía a todos y no tomar radiografía de tórax a ningún lactante con sospecha clínica de bronquiolitis viral. El desenlace principal fue la proporción de diagnósticos correctos. El horizonte temporal fue la evolución de la bronquiolitis. La perspectiva fue la del tercer pagador y los costos se obtuvieron de las tarifas vigentes en una clínica en la ciudad de Bogotá. Se realizaron análisis de sensibilidad determinísticos y probabilísticos. RESULTADOS: La estrategia de no realizar radiografía de tórax a ningún paciente fue dominante en relación con realizarla en todos los casos de manera rutinaria, con un costo promedio de US$ 111,0 y una tasa de diagnósticos correctos de 0,8020, comparados con los valores correspondientes de US$ 129,0 y 0,7873 para la estrategia de tomar radiografía rutinaria a todos estos pacientes. La variable más influyente fue el costo hospitalario de la neumonía. En el análisis de sensibilidad probabilístico, la estrategia de no radiografiar a ningún lactante fue dominante en 61,1 por ciento de las simulaciones. CONCLUSIONES: Los resultados sugieren que no realizar radiografía de tórax de rutina a lactantes con sospecha clínica de bronquiolitis viral es una estrategia costo-efectiva respecto a la práctica común de realizarla en todos estos casos, dado que arroja una mayor proporción de diagnósticos correctos a un menor costo promedio por paciente. No obstante, harán falta nuevos estudios con muestras más representativas de todos los establecimientos de salud e incluir la estrategia de tomar radiografía de tórax únicamente a pacientes que tengan predictores de anormalidades radiológicas.

OBJECTIVE: Estimate the cost-effectiveness of not taking chest x-rays of any infant with clinically suspected viral bronchiolitis versus routinely taking them of all such patients, the most common practice today in Colombia. METHODS: A cost-effectiveness study was conducted, comparing strategies of taking chest x-rays of all infants with clinically suspected viral bronchiolitis and not x-raying any of these infants. The principal outcome was the proportion of correct diagnoses. The time horizon was the clinical course of the bronchiolitis. The perspective was that of the third-party payer, and the costs were obtained from the rates in effect in a clinic in Bogotá. Deterministic and probabilistic sensitivity analyses were performed. RESULTS: The strategy of not taking a chest x-ray of any patient prevailed over that of routinely taking one in all cases, with an average cost of US$ 111.00 and a correct diagnosis rate of 0.8020, versus the respective values of US$ 129.00 and 0.7873 for the strategy of routinely x-raying all of these patients. The most influential variable was pneumonia-related hospital costs. In the probabilistic sensitivity analysis, the strategy of not x-raying any infant prevailed in 61.1 percent of the simulations. CONCLUSIONS: The results suggest that not taking routine chest x-rays of infants with clinically suspected viral bronchiolitis is a cost-effective strategy compared with the common practice of taking them in all cases, since the former yields a greater proportion of correct diagnoses at a lower average cost per patient. Nevertheless, new studies will be needed that have more representative samples from all of the health facilities and include the strategy of taking chest x-rays only of patients with predictors of radiologic abnormalities.

Estimation of Nursing Costs Based on Nurse Visit Time for Long-Term Care Services

PURPOSE: The purpose of this study was to estimate nursing costs and to establish appropriate nursing fees for long-term care services for community elders. METHODS: Seven nurses participated in data collection related to visiting time by nurses for 1,100 elders. Data on material costs and management costs were collected from 5 visiting nursing agencies. The nursing costs were classified into 3 groups based on the nurse's visit time under the current reimbursement system of long-term care insurance. RESULTS: The average nursing cost per minute was 246 won. The material costs were 3,214 won, management costs, 10,707 won, transportation costs, 7,605 won, and capital costs, 5,635 won per visit. As a result, the average cost of nursing services per visit by classification of nursing time were 41,036 won (care time <30 min), 46,005 won (care time 30-59 min), and 57,321 won (care time over 60 min). CONCLUSION: The results of the study indicate that the fees for nurse visits currently being charged for long-term care insurance should be increased. Also these results will contribute to baseline data for establishing appropriate nursing fees for long-term care services to maintain quality nursing and management in visiting nursing agencies.

Methods and Applications to estimate the Conversion Factor of Resource-based Relative Value Scale for Nurse-Midwife's Delivery Service in the National Health Insurance

PURPOSE: This paper analyzed alternative methods of calculating the conversion factor for nurse-midwife's delivery services in the national health insurance and estimated the optimal reimbursement level for the services. METHODS: A cost accounting model and Sustainable Growth Rate (SGR) model were developed to estimate the conversion factor of Resource-Based Relative Value Scale (RBRVS) for nurse-midwife's services, depending on the scope of revenue considered in financial analysis. The data and sources from the government and the financial statements from nurse-midwife clinics were used in analysis. RESULTS: The cost accounting model and SGR model showed a 17.6-37.9% increase and 19.0-23.6% increase, respectively, in nurse-midwife fee for delivery services in the national health insurance. The SGR model measured an overall trend of medical expenditures rather than an individual financial status of nurse-midwife clinics, and the cost analysis properly estimated the level of reimbursement for nurse-midwife's services. CONCLUSION: Normal vaginal delivery in nurse-midwife clinics is considered cost-effective in terms of insurance financing. Upon a declining share of health expenditures on midwife clinics, designing a reimbursement strategy for midwife's services could be an opportunity as well as a challenge when it comes to efficient resource allocation.

Economic problem of referred trauma cases in Siriraj Hospital.

To improve the service for referred trauma patients, the authors have to know the types of injury, the cost, and the reimbursement for each individual category. Therefore, the authors studied the characteristics of accident of patients transferred for treatment at Siriraj Hospital, including types of trauma (wounds), cost of treatment (excluding doctor's fees) and charges for treatments for each group. There were 678 trauma cases referred to the Division of Trauma Surgery, Department of Surgery, Faculty of Medicine, Siriraj Hospital from 1st September 2002 to 31st August 2003 and of these, 571 cases were admitted From the admitted cases, the most common injury was the musculoskeletal system (38.6%), followed by nervous system injury (15.1%), eye injury (8.1%), toxic substance injury (6.3%), burns (5.8%), and others. The total cost of treatment was 36,249,150 baht. The reimbursement was 30,135,709 baht. There were four categories where the reimbursed amount was below the actual cost. They were burns, followed by nervous system injury, eye injury and skin or subcutaneous tissue injury. To deal with the referred cases in trauma center level I, the center should prepare to manage the common trauma groups such as musculoskeletal system injury, nervous system injury and eye injury. Burns, nervous system injury, eye injury and skin or subcutaneous tissue injuries are the major groups that cost more than the reimbursement amount. The reimbursement of these groups should be reconsidered in the future to solve the problem.
