Incidencia, mortalidad y costos de la atención por cáncer de pulmón en el Instituto Mexicano del Seguro Social / Incidence, mortality and associated costs of lung cancer in the Mexican Institute of Social Security

Resumen: Objetivo: Analizar la tendencia temporal de la incidencia y la mortalidad del cáncer de pulmón, así como los costos asociados con su atención médica. Material y métodos: Se estimó el número de casos incidentes a partir de los egresos hospitalarios de 276 hospitales del Instituto Mexicano del Seguro Social (IMSS) entre 2006 y 2016. Se calcularon tasas de mortalidad crudas y ajustadas. Los costos del tratamiento ambulatorio y hospitalario se calcularon con base en los costos médico-técnicos de referencia o costos estándar de 2015. Resultados: Tanto la incidencia como la mortalidad muestran tendencia descendente. El costo de la atención médica de los 2 539 pacientes de 2017 fue de 42 millones de dólares americanos, con costo promedio por paciente de 16 527 dólares americanos. El gasto promedio anual de pensiones por invalidez es de 97.2 millones de pesos. Conclusiones: Es probable que la reducción del riesgo de enfermar y morir por cáncer de pulmón en derechohabientes del IMSS se deba a las medidas de control del humo de tabaco. Todavía es necesario establecer estrategias para diagnosticar y tratar a los pacientes en estadios tempranos.

Abstract: Objective: To describe temporal trends in lung cancer incidence, mortality and associated health care costs in the Mexican Institute of Social Security. Materials and methods: Incident cases were estimated from hospital discharges in 276 IMSS hospitals between 2006 and 2016. Crude and adjusted mortality rates were calculated. The costs of outpatient and inpatient treatment were calculated based on the medical-technical costs of reference o standard cost. Results: Both incidence and mortality had a decreased time trend. The cost of medical care for the 2 539 patients in 2017 was 42 million US dollars, with an average cost per patient of 16 537 US dollars. The cost per annum of disability pensions is 97.2 million pesos. Conclusions: It is likely that the reduction of the risk of getting sick and dying from lung cancer in IMSS affiliates is due to the control measures of tobacco smoke. It is still necessary to establish strategies to diagnose and treat patients in early stages.

Diabetes in rural Pondicherry, India: a population-based study of the incidence and risk factors.

Background: For India, the ‘diabetes capital’ of the world, it is essential to know the incidence of type 2 diabetes mellitus (T2DM) and its key determinants. As two thirds of Indians live in rural areas, a study was undertaken to assess the incidence and risk factors of T2DM in rural Pondicherry, India. Methods: In a population-based cohort study initiated in 2007, a sample of 1223 adults > 25 years of age from two villages of Pondicherry were selected using cluster random sampling. Data on risk factor exposure were collected using a structured questionnaire, anthropometric tests and fasting blood glucose assessment. During house visits, 1223 of 1403 invited subjects participated. Of these, 71 (5.8%) were found to have diabetes. In 2010–2011, 85% of the non-diabetics (979/1152) were followed up using the same protocol. We calculated the risk of T2DM per annum standardized by age and sex. Population estimates of the risk factors associated with T2DM were analysed using the Generalized Estimating Equation model and the Population Attributable Risk (PAR) for T2DM calculated. Results: During 2937 person-years (PY) of follow-up, 63 new cases of T2DM occurred, giving an incidence rate of 21.5/1000 PY. Almost one third (31.7%) of cases occurred in people aged below 40 years. The incidence was double among males (28.7/1000 PY; 95% confidence interval (CI): 21.0–38.7) compared with females (14.6/1000 PY; 95% CI: 9.4–21.7). Applying these rates to rural populations, it is estimated that each year 8.7 million people develop T2DM in rural India. Nearly half of the T2DM incidence was attributed to overweight/obesity and alcohol usage. Conclusion: T2DM incidence was 2% per year in adults in rural Pondicherry, India, with the rate increasing twice as fast in men. Increasing age, obesity, alcohol use and a family history of T2DM independently predicted the development of diabetes. As half of T2DM incidence was attributed to overweight/obesity and alcohol use, health promotion interventions focusing on maintaining an optimal weight and decreasing alcohol consumption may be effective in reducing the rise in T2DM cases.
