Uso de benzodiazepinas y fármacos relacionados en el seguro social para adultos mayores de Argentina / Use of benzodiazepines and related drugs in social security for older adults in Argentina

Resumen El uso clínico de las benzodiazepinas (BZD) y fármacos relacionados es un tema controversial, especialmente la prescripción prolongada en adultos mayores, que es contraria a las recomendaciones generales. Nuestro objetivo fue describir el uso de BZD y de los hipnóticos denominados fármacos Z (zolpidem, zopiclona y eszopiclona) en los adultos mayores beneficiarios del Instituto Nacional de Servicios Sociales para Jubilados y Pensionados (INSSJP-PAMI) de Argentina. Se realizó un estudio de utilización de medicamentos observacional, descriptivo, de corte transversal, a partir de la base de datos de dispensa de medicamentos del Instituto. Se incluyeron los beneficiarios de ambos sexos de 65 años y más. Se calculó para cada fármaco la prevalencia de uso en 2018 y las dosis diarias definidas (DDD) por cada 1000 habitantes/día (DHD). Se inclu yeron 3 864 949 beneficiarios (77.6 % de la población argentina de esa edad, 61.2 % mujeres), con 184 000 nonagenarios y más de 5000 centenarios. El 30.3 % recibió al me nos una dispensa de BZD o fármacos Z durante 2018, con mayor prevalencia de uso en mujeres (35.6%) que en varones (22.0%) y con aumento progresivo hasta los 85-89 años, y descenso posterior. Las BZD más recetadas fueron alprazolam (41.6%) y clonazepam (41.1%), seguidas por lorazepam (9.9%). La dispensa alcanzó 252.7 DHD, representado un promedio de 0.8 DDD por usuario y por día, valor que disminuyó con la edad. La prevalencia de uso encontrada está entre las más elevadas a nivel internacional, justificando la implementación de intervenciones clínicas y de salud pública para mejorar esta situación.

Abstract The clinical use of benzodiazepines (BZD) and related drugs is a controversial issue, especially prolonged prescription in older adults, which is contrary to general recommendations. Our objective was to describe the use of BZD and the hypnotics called Z drugs (zolpidem, zopiclone and eszopiclone) in elderly beneficiaries of the National Institute of Social Services for Retirees and Pensioners (INSSJP-PAMI) of Argentina. An observational, descriptive, cross-sectional drug use study was conducted based on the Institute's drug dispensing database. Beneficiaries of both sexes aged 65 years and over were included. The prevalence of use in 2018 and the defined daily doses (DDD) per 1000 inhabitants / day (DHD) were calculated for each drug. A total of 3 864 949 benefi ciaries were included (77.6% of the Argentine population of that age, 61.2% women), with 184 000 nonagenar ians and more than 5000 centenarians; 30.3% of whom received at least one dispensation of BZD or "Z drugs" during 2018, with a higher prevalence of use in women (35.6%) than in men (22.0%) and with a progressive increase until 85-89 years, with a subsequent decrease. The most prescribed BZDs were alprazolam (41.6%) and clonazepam (41.1%), followed by lorazepam (9.9%). The dispense drugs reached 252.7 DHD, representing an average of 0.8 DDD per user and per day, a value that decreased with age. The prevalence of use found is among the highest at international level, justifying the implementation of clinical and public health interventions to improve this situation.

Estimación de prevalencia de uso de medicamentos antihipertensivos en el programa de atención médico integral para adultos mayores de Argentina / Estimate of prevalence of antihipertensive drugs used in the Argentinian Integral Health Care Program for Elderly People

RESUMEN INTRODUCCIÓN La hipertensión arterial es muy prevalente en mayores de 60 años, dos tercios de los cuales están cubiertos en Argentina por el Programa de Atención Médica Integral (PAMI). El objetivo de este trabajo fue estimar la prevalencia de uso (PU) de antihipertensivos (AHT) en los adultos mayores de PAMI a partir de los datos de dispensa y describir su uso según tipo y cantidad. MÉTODOS Se realizó un estudio observacional retrospectivo. Se definieron como usuarios de AHT a los adultos de ambos sexos mayores de 60 años que recibieron al menos 2 envases de AHT durante 2018. Se comparó el resultado con el de la Encuesta Nacional de Factores de Riesgo (ENFR) 2013. RESULTADOS El 48,4% de los 4 397 188 afiliados de PAMI mayores de 60 años (63,8% mujeres; edad promedio: 74,3 años) usaron AHT durante 2018 (mujeres: 49,4%; varones: 46,6%). Este dato es similar al 47,8% observado en la ENFR 2013. La PU aumentó desde 37,5% a los 60-64 años hasta 55,1% a los 80-84 años, descendiendo luego. La PU ajustada varió desde 31,1% en Jujuy hasta 57,9% en Río Cuarto. Se dispensaron en promedio 13,6 envases/usuario/año. Los AHT más dispensados fueron los antagonistas del receptor de angiotensina II (36,5%), los betabloqueadores (27,0%) y los inhibidores de la enzima convertidora de angiotensina (23,1%). DISCUSIÓN El análisis de la base de datos administrativa de dispensas permite estimar datos epidemiológicos e identificar subpoblaciones destinatarias de intervenciones específicas.

ABSTRACT INTRODUCTION Arterial hypertension is highly prevalent in people older than 60, two thirds of which are covered in Argentina by the Comprehensive Medical Care Program (PAMI, according to the Spanish acronym). The objective of this work was to estimate the prevalence of antihypertensive drug (AHT) use in older adults of PAMI from the dispensation data and to describe its use in terms of type and quantity. METHODS A retrospective observational study was conducted. AHT users were defined as adults of both sexes over 60 years of age who received at least 2 packs of AHT during 2018. The result was compared with the one yielded by the National Risk Factor Survey 2013. RESULTS From the 4 397 188 beneficiaries of PAMI who were over 60 (63.8% women; average age: 74.3 years), 48.4% were AHT users during 2018 (women: 49.4%; men: 46.6%). This is similar to the 47.8% recorded in the National Risk Factor Survey 2013. The prevalence of use (PU) increased with age, from 37.5% at 60-64 years to 55.1% at 80-84 years, declining thereafter PU adjusted for age and sex varied from 31.1% in Jujuy to 57.9% in Rio Cuarto. On average, 13.6 packs/user/year were dispensed. The most widely distributed AHTs were angiotensin II receptor antagonists (36.5%), beta blockers (27.0%) and angiotensin converting enzyme inhibitors (23.1%). DISCUSSION The analysis of the administrative database of dispensed drugs allows the estimate of epidemiological data and to identify subpopulations that may benefit from specific interventions.

What is happening with not recommended drugs for dementia in Argentina? Prescription patterns and direct costs analysis.

OBJECTIVES: The only recommended pharmacological treatments for specific dementias are donepezil, galantamine, rivastigmine, and memantine (recommended drugs, RD). However, other drugs without recommendations (not recommended drugs, NRD) are often used to treat patients with cognitive impairment (CI) in Argentina. The INSSJyP is the largest health insurance in Argentina. The objective of this study is to analyze the prescription pattern, cost, and implications of NRD used for the treatment of CI in the INSSJyP. MATERIALS: This is a retrospective, population-based study of the INSSJyP outpatients' prescriptions database for drugs usually prescribed for CI during 2015. These data were compared with the same database in 2009. The number of "prescriptions" always refers to dispensed packages. RESULTS: A total of 3 255 438 packages of drugs usually indicated for CI were prescribed during 2015: 1 912 476 packages of RD (59%) and 1 342 962 packages of NRD (41%).Comparing the results with those obtained in 2009, there is a 148% gross increase in the prescription of both RD and NRD for CI, although the rates/1000 affiliates/year show a lesser rise for NRD (70.1%) compared to RD (103.9 %).The expenditure on CI drugs prescribed during 2015 was 77 million USD. NRD cost represented approximately 20 million USD. CONCLUSION: Inappropriate drug use increases health costs in developing countries. We found a high number of patients with a probable diagnosis of CI treated with NRD. It is extremely relevant that all the healthcare professionals can update their knowledge and modify behavioral insights about appropriate prescription for specific dementias.
