Severe osteoporosis: Principles for pharmacological therapy in Mexico. / Osteoporosis severa: fundamentos para su terapia farmacológica en México.

BACKGROUND: This article presents evidence and recommendations regarding the efficacy and safety of the approved and available therapies in Mexico to treat severe or established osteoporosis with the aim of developing a position regarding therapeutics in this stage of the disease, according to the descriptive cards of the National Drug Formulary of the National General Health Council of Mexico. METHODS: We performed a systematic and narrative review of the evidence of teriparatide and denosumab, from their pharmacological profile, effectiveness, and safety derived from clinical trials, as well as an analysis of the general recommendations of the national and international clinical practice guidelines. RESULTS: The evidence establishes that teriparatide and denosumab belong to different therapeutic classes, with biologically opposed mechanisms of action and indications of use, which are clearly differentiated in their respective national codes, therefore these drugs cannot be substitutable or interchangeable in severe osteoporosis therapy. Both represent the best options currently available for this stage of the disease; being similar in their efficacy in preventing new vertebral fragility fractures, with an RR of .35 (CI 95%; .22-.55) for teriparatide, and .32 (CI 95%: .26-.41) for denosumab. The absolute risk reduction is higher with teriparatide 9.3% (21 months) compared with denosumab at 4.8% (36 months). CONCLUSIONS: Our results agree with the recommendations available in national and international clinical practice guidelines, with both therapies proposed as a sequential, but not a substitute, treatment.

[Economic impact of hemophilia type A and B in Mexico]. / Impacto económico de la hemofilia tipo A y B en México.

BACKGROUND: The treatment of hemophilia generates a disproportionally large economic impact relative to its prevalence. OBJECTIVE: To determine the economic impact of hemophilia A and B in Mexico in 2011 from the perspective of public health institutions. METHODS: Hemophilia was epidemiologically characterized in Mexico during the year of interest, direct costs (diagnosis, monitoring or follow-up, care of bleeding events, and consumption of hemostatic factors), as well as absenteeism associated with illness (indirect costs) were estimated. Records, surveys and official data were supplemented by expert opinion to assess costs. RESULTS: The investment in hemostatic factors is the primary source of cost: 68.6 and 74.3% of total investment in hemophilia A and B, respectively. Sensitivity analysis showed that the most decisive variable is the cost of acquisition of hemostatic factors, including bypass agents. The second most important source of cost is the attention to bleeding events, being significantly higher in patients receiving on-demand treatment compared with those receiving prophylaxis. CONCLUSION: In Mexico, hemophilia is a condition whose treatment requires a large amount of financial resources associated with the cost of hemostatic factors and care of hemorrhage, the latter being lower in patients on prophylaxis relative to on-demand.

Catastrophic health expenses and impoverishment of households of patients with rheumatoid arthritis

Antecedentes. El costo de ciertas enfermedades puede dar lugar a gastos catastróficos y el empobrecimiento de las familias sin apoyo financiero por los organismos del Estado y otros. Objetivo. Determinar el impacto socioeconómico de la artritis reumatoide (AR) sobre costos en el contexto de los gastos catastróficos y el empobrecimiento. Pacientes y métodos. Se trata de una cohorte anidada en un estudio transversal y multicéntrico sobre el costo de la AR en los hogares mexicanos con cobertura parcial, completa o privado de salud. Los gastos catastróficos se definieron como aquellos que ocupaban > 30% del ingreso total del hogar. Empobrecimiento se definió como los hogares que no podían pagar la canasta básica de alimentos de México (CBA). Resultados. Se incluyeron 262 pacientes con un ingreso familiar promedio mensual (dólares americanos) de $ 376 (0-18,890.63). En total, el 50,8%, 35,5% y 13,7% de los pacientes tenían cobertura médica parcial, completa o privado, respectivamente. El costo anual de la AR fue de $ 5,534.8 por paciente (65% los costos directos, el 35% indirecto).La AR generó gastos catastróficos en el 46,9% de los hogares, que en el análisis de regresión logística se asociaron significativamente con el tipo de cobertura de salud (OR 2,7, IC 95% 1.6 a 4.7) y la duración de la enfermedad (OR 1,024, IC del 95% 1.002-1,046). El empobrecimiento se produjo en el 66,8% de los hogares y se asoció con gastos catastróficos (OR 3,6, IC 95% 1.04 a 14.1), los altos puntajes del cuestionario de Evaluación de Salud (OR 4,84 IC 95%: 1,01 a 23,3), y el nivel socioeconómico bajo (OR 4.66, IC 95%: 1.37-15.87). Conclusión. El costo de la AR en los hogares mexicanos, en particular los que no tienen cobertura de salud completa lleva a los gastos catastróficos y el empobrecimiento. Estos hallazgos podrían ser los mismo en los países con sistemas de salud fragmentados (AU)

Background: The cost of certain diseases may lead to catastrophic expenses and impoverishment of households without full financial support by the state and other organizations. Objective: To determine the socioeconomic impact of the rheumatoid arthritis (RA) cost in the context of catastrophic expenses and impoverishment. Patients and methods: This is a cohort-nested cross-sectional multicenter study on the cost of RA in Mexican households with partial, full, or private health care coverage. Catastrophic expenses referred to health expenses totaling >30% of the total household income. Impoverishment defined those households that could not afford the Mexican basic food basket (BFB). Results: We included 262 patients with a mean monthly household income (US dollars) of $376 (0-18,890.63). In all, 50.8%, 35.5%, and 13.7% of the patients had partial, full, or private health care coverage, respectively. RA annual cost was $ 4653.0 per patient (65% direct cost, 35% indirect). RA cost caused catastrophic expenses in 46.9% of households, which in the logistic regression analysis were significantly associated with the type of health care coverage (OR 2.7, 95%CI 1.6-4.7) and disease duration (OR 1.024, 95%CI 1.002-1.046). Impoverishment occurred in 66.8% of households and was associated with catastrophic expenses (OR 3.6, 95%CI 1.04-14.1), high health assessment questionnaire scores (OR 4.84 95%CI 1.01-23.3), and low socioeconomic level (OR 4.66, 95%CI 1.37-15.87). Conclusion: The cost of RA in Mexican households, particularly those lacking full health coverage leads to catastrophic expenses and impoverishment. These findings could be the same in countries with fragmented health care systems (AU)

[Estimation of health-care costs for cervical uterine neoplasm]. / Costos de atención médica por cáncer cervicouterino.

OBJECTIVE: to value diagnostic stage and direct costs due to cervical cancer in insured workers and IMSS beneficiaries patients, during first year of treatment. METHODS: 80 records of patients with confirmed diagnosis of cervical cancer during 2000-2003 were analyzed. The study was made under provider public health services perspective, with focus in costs incidence during 2009. RESULTS: 27 (34 %) of total records corresponding to insured worker and 53 (66 %) to beneficiaries. No differences were finding in diagnostic stage. In bout groups stage II was the most common. The cost due medical care adds up to $91,064.00 during first year of treatment in workers. The main costs were identified in sickness absence certification (31 %), image exams (24 %) consulting room (19 %), radiotherapy sessions (10 %) and hospitalization (9 %). CONCLUSIONS: cervical cancer is a frequent disease that affects women in their productive and reproductive age. Frequently their diagnosis is made in advanced stages, which increase medical attention cost. It is convenient to introduce more effective preventive actions, including the workplace.

Estimation of health-care costs for work-related injuries in the Mexican Institute of Social Security.

BACKGROUND: Data on the economic consequences of occupational injuries is scarce in developing countries which prevents the recognition of their economic and social consequences. This study assess the direct heath care costs of work-related accidents in the Mexican Institute of Social Security, the largest health care institution in Latin America, which covered 12,735,856 workers and their families in 2005. METHODS: We estimated the cost of treatment for 295,594 officially reported occupational injuries nation wide. A group of medical experts devised treatment algorithms to quantify resource utilization for occupational injuries to which unit costs were applied. Total costs were estimated as the product of the cost per illness and the severity weighted incidence of occupational accidents. RESULTS: Occupational injury rate was 2.9 per 100 workers. Average medical care cost per case was $2,059 USD. The total cost of the health care of officially recognized injured workers was $753,420,222 USD. If injury rate is corrected for underreporting, the cost for formal injured workers is 791,216,460. If the same costs are applied for informal workers, approximately half of the working population in Mexico, the cost of healthcare for occupational injuries is about 1% of the gross domestic product. CONCLUSIONS: Health care costs of occupational accidents are similar to the economic direct expenditures to compensate death and disability in the social security system in Mexico. However, indirect costs might be as important as direct costs.

Direct medical costs for partial refractory epilepsy in Mexico.

BACKGROUND: The aim was to determine the direct medical costs in patients with partial refractory epilepsy at the Mexican Institute of Social Security (IMSS) in Mexico. METHODS: We carried out a multicenter, retrospective-cohort partial-economic evaluation study of partial refractory epilepsy (PRE) diagnosed patients and analyzed patient files from four secondary- and tertiary-level hospitals. PRE patients >12 years of age with two or more antiepileptic drugs and follow-up for at least 1 year were included. The perspective was institutional (IMSS). Only direct healthcare costs were considered, and the timeline was 1 year. Cost techniques were microcosting, average per-service cost, and per-day cost, all costs expressed in U.S. dollars (USD, 2004). RESULTS: We reviewed 813 files of PRE patients: 133 had a correct diagnosis, and only 72 met study inclusion criteria. Fifty eight percent were females, 64% were <35 years of age, 47% were students, in 73% maximum academic level achieved was high school, and 53% were single. Fifty one percent of cases experienced simple partial seizures and 94% had more than one monthly seizure. Annual healthcare cost of the 72 patients was 190,486 USD, ambulatory healthcare contributing 76% and hospital healthcare with 24%. CONCLUSIONS: Annual mean healthcare cost per PRE patient was 2,646 USD; time of disease evolution and severity of the patient's illness did not affect costs significantly.
