RESUMO
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.

OBJECTIVE: To analyze the prescribing pattern of psychotropic drugs to affiliates over 60 years of age at the National Institute of Social Services for Retirees and Pensioners of Argentina (PAMI). MATERIALS AND METHODS: We conducted a retrospective study of the at the National Institute of Social Services for Retirees and Pensioners of Argentina (PAMI) database on the population over 60 years of age who received at least one psychotropic drug during 2016. RESULTS: During the year 2016, 30% of the population over 60 years of age received the prescription of at least one psychotropic drug. There was a greater prescription of psychotropic drugs to women than to men (75.3% vs. 24.7%). Of the drugs prescribed, 67% were benzodiazepines, 20% were antidepressants, 9% were antipsychotics and 4% were non-benzodiazepine hypnotics. 54% of the drugs prescribed were clonazepam and alprazolam. 21% of the population received three or more prescriptions during the period studied. There was a relatively greater prescription of psychotropic drugs in the population of 75 years old or older. CONCLUSIONS: Taking into account the risks of adverse effects, interactions and the inclusion of some of these drugs among those that should not be prescribed among older adults, the high prescription rate of some of these drugs is alarming. It is necessary to develop strategies among general practitioners, specialists and also among the general population in order to reduce the prescription of psychotropic drugs.

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 beneficiaries were included (77.6% of the Argentine population of that age, 61.2% women), with 184 000 nonagenarians 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.

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 $234â¯893.35 (95% CI, $225â¯565.35 to $237â¯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.

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.
RESUMO
OBJECTIVE: Eating disorders are psychiatric illnesses of important prevalence in Argentina. Some typical characteristics of adolescence, such as body image fragility, media influence and social pressure lead partly into the development of eating disorders at that age. The objective of our study was to explore the eating behaviors, attitudes and obsessive-compulsive traits of the adolescents of Buenos Aires City. METHODS: A questionnaire survey was administered to 380 students of 5 Buenos Aires high schools (mean age:16,8 years old) and their answers were analyzed. RESULTS: Almost 50% of the adolescents were not satisfied with their weight, 43% of them has been on a diet at least once (the majority because of aesthetic reasons). A percentage of 23,5 had bulimic behaviors, 34,5% had a high number of obsessive-compulsive traits. Women were significantly more dissatisfied with their weight, had been on more diets and had more bulimic behaviors and obsessive-compulsive traits. CONCLUSIONS: Weight dissatisfaction and bulimic behaviors are frequent in adolescents of Buenos Aires City, specially among women. Preventive measures against eating disorders should be done on this population.

UNLABELLED: The epidemiological projections show that the problems of Mental Health were the main health challenge during the last decade. This situation is particularly worring in our region. The poor operative data in relation to the care of the mental disorders prevent the elaboration of plans on the basis of secure data. METHODOLOGY: Records of externation were analized during the period between 1994-1998 in the men Psychiatric Internation Unity in the Psychopatology Service of the Hospital Piñero in Buenos Aires, which is part of the public health service of the city. RESULTS: an average time of internation of 42.8 days was reported (SD 40,3), which was higher than the 11 days reported in institutions of the private health services. An increasing proportional diagnosis of Bipolar Disorder was reported (chi square corresponding to tendencies P<0.01, lineality P<0.001) and a significative decline in the number of diagnosis of Schizophrenia (chi square corresponding to tendencies P<0.05; lineality P<0.05). In this way, the ratio of the diagnosis of Schizophrenia and Bipolar Disorder changed from 7:1 in 1994 to 1,7:1 in 1998. CONCLUSIONS: A variation in the diagnostic habits was observed, suggesting that affective disorders were underdiagnosticated. This tendency was corrected latter. Similar remarks made by other services in the same region support this interpretation of the data.
