Third Argentine Consensus statement on management Bipolar Disorders. Section 2 A: Comprehensive treatment of the bipolar disorders in adults / Tercer Consenso Argentino sobre el manejo de los Trastornos Bipolares. Segunda Parte A: Tratamiento integral de los trastornos bipolares en el adulto.

This document constitutes the second section A of the Third Argentine Consensus on the Management of Bipolar Disorders, focused on synthesizing the most updated evidence on therapeutic approaches for adult patients. The aim of this section (2A) is to provide therapeutic recommendations for managing bipolar disorders in adults. In addition, the scope of this current manuscript outlines recommendations on the use of treatment guidelines, levels of evidence available to support these recommendations, general considerations for the treatment of bipolar disorders, the so-called pseudoresistance and adherence to treatment, general considerations on psychological therapies, as well as long term treatment of bipolar disorders.

Este documento corresponde a la segunda parte del Tercer Consenso Argentino sobre el manejo de los trastornos bipolares, enfocada en sintetizar la evidencia actualizada sobre los abordajes terapéuticos de esta patología en los pacientes adultos. Siguiendo la metodología descripta en la primera parte del Consenso, el panel de expertos realizó una exhaustiva revisión de la bibliografía y, como consecuencia de un posterior debate sobre la información disponible, se generó esta sección A del segundo documento que abarca el tratamiento integral de las personas adultas que padecen este trastorno. Durante la etapa de debate y discusión de estas guías, se decidió incorporar algunos puntos que estimamos serán de gran utilidad para el equipo interdisciplinario encargado del manejo de pacientes con trastornos bipolares.  En tal sentido, en la sección A de la segunda parte de este documento, se podrán encontrar las recomendaciones generales para el uso de las guías de tratamiento, los niveles de evidencia disponibles para sustentar las recomendaciones, las consideraciones generales del tratamiento de los trastornos bipolares, el fenómeno de pseudorresistencia y adherencia al tratamiento, las consideraciones generales sobre el abordaje psicológico, así como el tratamiento a largo plazo de los trastornos bipolares.

Associations Among Loneliness, Purpose in Life and Subjective Cognitive Decline in Ethnoracially Diverse Older Adults Living in the United States.

Subjective cognitive decline (SCD), which precedes Mild Cognitive Impairment and dementia, may be affected by purpose in life (PiL) and loneliness in older adults. We investigated associations among PiL, loneliness, and SCD in US Latino (n = 126), Black (n = 74), Asian (n = 33), and White (n = 637) adults. Higher PiL predicted lower SCD in all groups (p-values < .012), except Black participants. Lower loneliness predicted lower SCD in Latino and White groups (p-values < .05), and PiL moderated this association in White adults. PiL and loneliness may play important roles in cognitive decline. Differential predictors of SCD suggest differential targets for preventing cognitive decline and dementia across ethnoracial groups.

Do we treat dementia of the Alzheimer type or Alzheimer's disease? Anti-dementia drugs in the era of biomarkers / ¿Tratamos la demencia tipo Alzheimer o la enfermedad de Alzheimer? Fármacos antidemenciales en la era de los biomarcadores.

Approved drug treatments for Alzheimer´s disease (AD) are symptomatic and don´t modify the disease course. These include acetylcholinesterase inhibitors (AchI) and N-methyl-D-aspartate receptor antagonist, memantine. Around 20 years ago, these drugs were approved for Alzheimer type Dementia. This wasbased on clinical trials which inclusion criteria were focused on a clinical amnestic AD presentation. At that time, subjects with an atypical AD clinical presentation or biomarkers were not included in the pharmacological trials. New biomarkers that detect amyloid and neurodegeneration have allowed us to evaluate pathological changes compatible with AD. These new advances from aclinical and biomarkers perspective allowed a diagnostic criteria update; going from an exclusively clinical criteria to one that is hybrid: clinical presentation and biomarkers based criteria.New biomarkers facilitate the early diagnosis of AD and other dementias.However, they also generate new challenges and questions regarding the adequate pharmacological treatment.There is a need for clinical trials that evaluate anti-dementia drug's efficacy based on current diagnostic criteria (clinical profile and biomarkers) and new practice guidelines. In addition, regulatory authorities should update ACHI and memantine indications.This will help doctors to prescribe the best possible treatment for this specific population without increasing risks.

Los tratamientos farmacológicos aprobados para la enfermedad de Alzheimer (EA) son sintomáticos y no modifican el curso de la enfermedad. Estos incluyen inhibidores de la acetilcolinesterasa (IACE) y el antagonista del receptor de N-metil-D-aspartato, memantina. Estos medicamentos fueron aprobados para la demencia de tipo Alzheimer (DTA) hace unos 20 años, basándose en ensayos clínicos centrados en la presentación clínica amnésica de la EA sin considerar biomarcadores o presentaciones clínicas atípicas de EA. Los nuevos biomarcadores que detectan amiloide y neurodegeneración nos han permitido evaluar cambios patológicos compatibles con la EA. Estos nuevos avances desde la perspectiva de los biomarcadores y clínicos han llevado a una actualización de los criterios diagnósticos, pasando de criterios exclusivamente clínicos a criterios híbridos: clínicos y basados en marcadores. Estos biomarcadores facilitan el diagnóstico precoz de la EA y otras demencias; sin embargo, a veces generan desafíos y replanteos en relación al tratamiento farmacológico adecuado. Sería útil implementar ensayos clínicos que evalúen la eficacia de los fármacos aprobados para la enfermedad de Alzheimer, en su momento con criterios de demencia tipo Alzheimer en función de los criterios diagnósticos actuales (perfil clínico y biomarcadores). Además, la actualización de la indicación de prescripción de IACE y memantina por parte de las autoridades regulatorias especificando con más detalle la población objetivo ayudaría a prescribir el mejor tratamiento posible a los pacientes sin aumentar los riesgos.

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.

Third Argentine Consensus statement on management Bipolar Disorders. Section1: introduction and general concepts / Tercer Consenso Argentino sobre el manejo de los Trastornos Bipolares. Primera Parte: introducción, método de trabajo y generalidades.

The Third Argentine Consensus on the management of bipolar disorders (TB) is an initiative of the Argentine Association of Biological Psychiatry (AAPB). As a reference document, this consensus pursues two main objectives: on the one hand, to summarize and systematize the best available evidence on the comprehensive management of this pathology; on the other, to provide a useful, up-to-date instrument for psychiatrists, multidisciplinary teams dedicated to mental health, and government agencies. During a period of approximately six months of work -that is, from May to October 2022- a committee of experts made up of 18 professionals and representatives of the three most important Psychiatry and Mental Health associations in Argentina (that is, the AAPB, the Argentine Association of Psychiatrists, AAP, and the Association of Argentine Psychiatrists, APSA) have focused on updating the information regarding TB. Finally, this document was prepared as a result of an exhaustive review of the bibliography published to date, which was strategically divided into three parts: the first deals with the generalities of TB; the second deals with the comprehensive treatment of the pathology; finally, the third analyzes TB in the context of special situations.

El Tercer Consenso Argentino sobre el manejo de los Trastornos Bipolares (TB) es una iniciativa de la Asociación Argentina de Psiquiatría Biológica (AAPB). Como documento de referencia, este consenso persigue dos objetivos principales: por un lado, resumir y sistematizar la mejor evidencia disponible sobre el manejo integral de esta patología; por el otro, proporcionar un instrumento útil y actualizado a psiquiatras, a equipos multidisciplinarios abocados a la salud mental y a organismos gubernamentales. Durante un período de aproximadamente seis meses de trabajo -desde mayo a octubre de 2022- un comité de expertos integrado por 18 profesionales y por representantes de las tres asociaciones de Psiquiatría y Salud Mental más importantes de la Argentina: la AAPB, la Asociación Argentina de Psiquiatras, (AAP) y la Asociación de Psiquiatras Argentinos (APSA), se abocaron a actualizar la información respecto de los TB. Finalmente, y como resultado de una exhaustiva revisión de la bibliográfica publicada hasta la actualidad, se confeccionó este documento que fue dividido estratégicamente en tres partes: la primera versa acerca de las generalidades del TB; la segunda aborda el  tratamiento integral de la patología; y, por último, la tercera analiza los TB en el contexto de situaciones especiales.

The impact of COVID-19 on the well-being and cognition of older adults living in the United States and Latin America.

BACKGROUND: In the COVID-19 pandemic, older adults from vulnerable ethnoracial groups are at high risk of infection, hospitalization, and death. We aimed to explore the pandemic's impact on the well-being and cognition of older adults living in the United States (US), Argentina, Chile, Mexico, and Peru. METHODS: 1,608 (646 White, 852 Latino, 77 Black, 33 Asian; 72% female) individuals from the US and four Latin American countries aged ≥ 55 years completed an online survey regarding well-being and cognition during the pandemic between May and September 2020. Outcome variables (pandemic impact, discrimination, loneliness, purpose of life, subjective cognitive concerns) were compared across four US ethnoracial groups and older adults living in Argentina, Chile, Mexico, and Peru. FINDINGS: Mean age for all participants was 66.7 (SD = 7.7) years and mean education was 15.4 (SD = 2.7) years. Compared to Whites, Latinos living in the US reported greater economic impact (p < .001, ηp 2  = 0.031); while Blacks reported experiencing discrimination more often (p < .001, ηp 2  = 0.050). Blacks and Latinos reported more positive coping (p < .001, ηp 2  = 0.040). Compared to Latinos living in the US, Latinos in Chile, Mexico, and Peru reported greater pandemic impact, Latinos in Mexico and Peru reported more positive coping, Latinos in Argentina, Mexico, and Peru had greater economic impact, and Latinos in Argentina, Chile, and Peru reported less discrimination. INTERPRETATION: The COVID-19 pandemic has differentially impacted the well-being of older ethnically diverse individuals in the US and Latin America. Future studies should examine how mediators like income and coping skills modify the pandemic's impact. FUNDING: Massachusetts General Hospital Department of Psychiatry.

[Reduction of social coverage for symptomatic slow-acting drugs for osteoarthritis: a disinvestment initiative in Argentina, 2015-2017]. / Reducción de la cobertura social para los fármacos antiartrósicos sintomáticos de acción lenta: una iniciativa de desinversión en Argentina, 2015-2017.

In April 2016, the National Institute of Social Services for Retirees and Pensioners discontinued its policy of 100% coverage for 159 drugs (the "social subsidy"), including symptomatic slow-acting drugs for osteoarthritis (SYSADOAs), due to insufficient evidence of significant clinical benefit. We evaluated the effect of this measure on the use of SYSADOAs as well as non-steroidal anti-inflammatory drugs (NSAIDs), which were unaffected by this policy change. We compared outpatient dispensations of SYSADOAs and NSAIDs from 2015 to 2017, measuring dispensed units, retail price, and out-of-pocket expenses for beneficiaries each month. After the change in coverage, there was a 61.6% total decrease in SYSADOA units dispensed, and a 63.4% decrease in the final sales price to the public, measured in constant values. Dispensation was not reoriented towards NSAIDs, which fell by 6.1%. The incidence of new treatments decreased (from 6.4 to 3.3 treatments per 1,000 beneficiaries per month), as did their continuity. Beneficiaries' out-of-pocket spending on SYSADOAs increased by 75.8% (at constant values). Disinvestment in interventions with questionable therapeutic value is an important tool in working toward the sustainability of health systems.

Evaluamos el efecto de esta medida sobre la utilización de SySADOA y de los antiinflamatorios no esteroides (AINE), no afectados por la medida. Se compararon las dispensas ambulatorias de los SySADOA y los AINE de 2015 a 2017, midiendo unidades dispensadas, precio de venta al público y gasto de bolsillo del beneficiario para cada mes. Luego de la medida, descendieron un 61,6% los envases de SySADOA dispensados y un 63,4% el monto total del precio de venta al público, medido en valores constantes. La dispensa no se reorientó hacia los AINE, que descendieron un 6,1%. Disminuyó tanto la incidencia de nuevos tratamientos (de 6,4 a 3,3 tratamientos por 1.000 beneficiarios por mes) como su continuidad. El gasto de bolsillo de los beneficiarios en SySADOA aumentó un 75,8% (a valores constantes). La desinversión en intervenciones de valor terapéutico cuestionable es una herramienta valiosa para la sustentabilidad de los sistemas de salud.

Dementia in Latin America: Paving the way toward a regional action plan.

Across Latin American and Caribbean countries (LACs), the fight against dementia faces pressing challenges, such as heterogeneity, diversity, political instability, and socioeconomic disparities. These can be addressed more effectively in a collaborative setting that fosters open exchange of knowledge. In this work, the Latin American and Caribbean Consortium on Dementia (LAC-CD) proposes an agenda for integration to deliver a Knowledge to Action Framework (KtAF). First, we summarize evidence-based strategies (epidemiology, genetics, biomarkers, clinical trials, nonpharmacological interventions, networking, and translational research) and align them to current global strategies to translate regional knowledge into transformative actions. Then we characterize key sources of complexity (genetic isolates, admixture in populations, environmental factors, and barriers to effective interventions), map them to the above challenges, and provide the basic mosaics of knowledge toward a KtAF. Finally, we describe strategies supporting the knowledge creation stage that underpins the translational impact of KtAF.

Effect of a Social Norm Email Feedback Program on the Unnecessary Prescription of Nimodipine in Ambulatory Care of Older Adults: A Randomized Clinical Trial.

Importance: Nimodipine is a highly prescribed drug for the treatment of cognitive impairment and dementia in Argentina. There is little evidence to support the use of nimodipine for cognitive impairment and dementia. Objective: To test the effectiveness of a behavioral intervention based on social norm feedback to reduce prescription of nimodipine for cognitive impairment in Argentina. Design, Setting, and Participants: This pragmatic parallel-group randomized clinical trial included 2 arms with a 1:1 allocation ratio. General practitioner physicians in the national health care system for older adults in Argentina (INSSJP-PAMI) with history of high nimodipine prescription rate were enrolled. The study was conducted from May 2019 to October 2019, and data were analyzed from November 2019 to February 2020. Interventions: The treatment group received 2 emails with evidence-based information about nimodipine plus the individual's level of nimodipine prescription compared with their peers. The control group received 2 emails with general information about the risks of overprescription in older adults. Main Outcomes and Measures: The primary outcome was the cumulative number of nimodipine prescriptions per 1000 prescriptions of all drugs made by the targeted physicians during the 6 months of the study. Secondary outcomes included annual monetary savings attributable to the intervention and physicians' qualitative perceptions of the acceptability of the procedure. Results: Of 1811 physicians enrolled, 906 physicians (354 [39.1%] women; mean [SD] age, 57.10 [10.73] years) were randomized to treatment and 905 participants (331 [36.6%] women; mean [SD] age, 56.49 [10.47] years) to the control group. Physicians in the treatment group wrote a mean of 93.25 (95% CI, 89.27 to 97.24) prescriptions of nimodipine, compared with 98.99 (95% CI, 95.00 to 102.98) prescriptions among practitioners in the control group during the half-year of the intervention (mean difference, -5.73 [95% CI, -11.38 to -0.10] prescriptions; P = .046), which meant a 5.79% reduction. Regression analysis revealed a significant association of the group condition with number of prescriptions per 1000 total prescriptions when controlling for baseline prescriptions (B = -0.312 [95% CI, -0.465 to -0.160]; P < .001). The observed difference corresponds to a 4.48% reduction in nimodipine prescriptions per 1000 prescriptions of all drugs made by physicians in the treated group compared with the control group. Physicians who effectively opened the email in the treatment group (427 physicians [47.1%]) prescribed the drug 11.3% less compared with the control group (426 physicians) (mean difference, -10.78 [95% CI, -18.53 to -3.03] prescriptions; P = .006). Expenditures were 7.18% lower in the treatment group, resulting in an estimated annual net cost benefit of US $234 893.35 (95% CI, $225 565.35 to $237 112.30). Conclusions and Relevance: In this randomized clinical trial, the social norm email feedback program showed an effect on curbing the nonrecommended prescription of nimodipine. It was highly cost-effective and well accepted by participants. Trial Registration: ISRCTN.org identifier: ISRCTN17823729.

The impact of SARS-CoV-2 in dementia across Latin America: A call for an urgent regional plan and coordinated response.

The SARS-CoV-2 global pandemic will disproportionately impact countries with weak economies and vulnerable populations including people with dementia. Latin American and Caribbean countries (LACs) are burdened with unstable economic development, fragile health systems, massive economic disparities, and a high prevalence of dementia. Here, we underscore the selective impact of SARS-CoV-2 on dementia among LACs, the specific strain on health systems devoted to dementia, and the subsequent effect of increasing inequalities among those with dementia in the region. Implementation of best practices for mitigation and containment faces particularly steep challenges in LACs. Based upon our consideration of these issues, we urgently call for a coordinated action plan, including the development of inexpensive mass testing and multilevel regional coordination for dementia care and related actions. Brain health diplomacy should lead to a shared and escalated response across the region, coordinating leadership, and triangulation between governments and international multilateral networks.

The power of knowledge about dementia in Latin America across health professionals working on aging.

INTRODUCTION: Expert knowledge is critical to fight dementia in inequitable regions like Latin American and Caribbean countries (LACs). However, the opinions of aging experts on public policies' accessibility and transmission, stigma, diagnostic manuals, data-sharing platforms, and use of behavioral insights (BIs) are not well known. METHODS: We investigated opinions among health professionals working on aging in LACs (N = 3365) with regression models including expertise-related information (public policies, BI), individual differences (work, age, academic degree), and location. RESULTS: Experts specified low public policy knowledge (X2  = 41.27, P < .001), high levels of stigma (X2  = 2636.37, P < .001), almost absent BI knowledge (X2  = 56.58, P < .001), and needs for regional diagnostic manuals (X2  = 2893.63, df = 3, P < .001) and data-sharing platforms (X2 = 1267.5, df = 3, P < .001). Lack of dementia knowledge was modulated by different factors. An implemented BI-based treatment for a proposed prevention program improved perception across experts. DISCUSSION: Our findings help to prioritize future potential actions of governmental agencies and non-governmental organizations (NGOs) to improve LACs' dementia knowledge.

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.
