A multifactorial intervention to lower potentially inappropriate medication use in older adults in Argentina.

BACKGROUND: Adverse drug reactions are a common cause of potentially avoidable harm, particularly in older adults. AIMS: To evaluate the feasibility and efficacy of a pilot multifactorial intervention to reduce potentially inappropriate medication (PIM) use in older adults. METHODS: We conducted a phase 2, feasibility, open-label study in the ambulatory setting of an integrated healthcare network in Buenos Aires, Argentina. We recruited primary care physicians (PCPs) and measured PIM use in a sample of their patients (65 years or older). Educational workshops for PCPs were organized with the involvement of clinician champions. Practical deprescribing algorithms were designed based on Beers criteria. Automatic email alerts based on specific PIMs recorded in each patient's electronic health record were used as a reminder tool. PCPs were responsible for deprescribing decisions. We randomly sampled 879 patients taking PIMs from eight of the most commonly used drug classes at our institution and compared basal (6 months prior to the intervention) and final (12 months after) prevalence of PIM use using a test of proportions. RESULTS: There was a significant reduction (p < 0.05) in all drug classes evaluated. Non-Steroidal Anti-Inflammatory Drugs (basal prevalence 5.92%; final 1.59%); benzodiazepines (10.13%; 6.94%); histamine antagonists (7.74%; 3.07%); opioids (2.16%; 1.25%); tricyclic antidepressants (8.08%; 4.10%); muscle relaxants (7.74%; 3.41%), anti-hypertensives (3.53%; 1.82%) and oxybutynin (2.96%; 1.82%). The absolute reduction in the overall prevalence was 8.5 percentage points (relative reduction of 51.4%). CONCLUSION: This multifactorial intervention is feasible and effective in reducing the use of potentially inappropriate medication in all drug classes evaluated.

[Study of the performance of complex activities of daily living in a population of patients with mild cognitive impairment. Mild functional impairment: A new clinical entity?] / Estudio del desempeño de las actividades complejas de la vida diaria en una población de pacientes con Deterioro Cognitivo Leve. Deterioro Funcional Leve: ¿una nueva entidad clínica?

Several papers describe functional changes in the aging population, and its relevance in the early cognitive impairment detection. Alterations in instrumental activities would constitute a diagnostic marker of MCI and predict the progression to Dementia. In order to count on a tool to evaluate the performance in the use of new technologies we have designed a new protocol, Complex Functional Study (CFS), that quantifies performance and functional changes Related to previous states. OBJECTIVES: To compare CFS scores in patients with MCI with a control group without cognitive impairment (CD) and verify their diagnostic performance to detect complex function alterations in reference too the functional scales, Instrumental Activities of Daily Living (AVDI) and Disability Assessment for Dementia (DAD). METHODS: Patients with MCI and controls were included. All subjects were evaluated with a neurocognitive battery, and functional scales (EFE).STATA software version 14.2 was used for data analysis. RESULTS: 269 recruited patients older than 65 years old, 173 with diagnosis of MCI and 96 controls. The MCI patients obtained significantly higher EFE scores tan subjects without DC (p < 0,001).The EFE presented a greater sensitivity to detect the functional alteration (EFE 81.5%, AVDI 25.9%, DAD 18.5%). CONCLUSIONS: The EFE is an instrument of optimal clinical value, with good sensitivity to identify the alteration of the complex activities of daily life in patients with MCI. The results allow to characterize a profile compatible with Light Functional Impairment.

[Prevalence of pain among patients admitted to a clinical hospital]. / Prevalencia de dolor en la internación en un hospital de alta complejidad de Argentina.

BACKGROUND: Pain prevalence during hospital admission is variable, with estimates ranging from 32 to 77%. AIM: To determine pain prevalence during admission to a clinical hospital. MATERIAL AND METHODS: Patients admitted to medical and surgical wards were interrogated about the presence of pain within 48 to 72 hours after admission. Subjective pain was analyzed using a scale ranging from 0 to 10. Data was analyzed separately for medical, surgical, and obstetrical patients. RESULTS: A total of 736 patients aged 18 to 94 years (416 women) were recruited. Pain prevalence at 48 hours after admission was 56% (95% confidence intervals (CI (52.7 to 60.1). Pain prevalence in medical, surgical and obstetric patients was 37% (95% CI 31.4 to 42.1), 70% (95% CI 64.5 to 75.5) and 77% (95% CI 68.6 to 84), respectively. The median pain intensities in medical, surgical, and obstetrical patients were 7 (interquartile range (IQR) 6-8), 7 (IQR 5-8) y 7 (IQR 5-8), respectively. CONCLUSIONS: The prevalence of pain among patients admitted to the hospital is high, especially in obstetric and surgical units.

[Herpes zoster in elderly adults in a community hospital in Buenos Aires. June 2013-May 2014]. / Herpes zoster en adultos mayores en un hospital privado de la ciudad de Buenos Aires, junio 2013 - mayo 2014.

Herpes zoster (HZ) is caused by reactivation of the varicella zoster virus. Its main risk factor is increasing age and comorbidities. There are limited data on the characteristics of HZ in South America, especially in the elderly. We analyzed epidemiological and clinical characteristics of 340 patients over 60 years assisted for HZ, between June 2013 and May 2014. The average age was 74 years (60-100), 62% (210) had thoracic location; 75% (255) of the initial consultations were held in guards; 68% (143) had pain and vesicles, and 4% (14) only pain at baseline. Pain persisted after finishing the episode in 41% (139). The diagnosis was made between 1 and 3 days from the beginning of the episode in 53% (180 patients). Average number of visits per episode was 3.6 (1-24). Antiviral treatment was supplied to 91% (309); however it was inadequate in dose or time in 49.1% (167 cases). Pain treatment was indicated in 66% (224). Most frequently used drugs (alone or in combination) were non-steroidal painkillers (43%, 146), pregabalin (30%, 102), opiates (24%, 82), and steroids (12%, 41); 9% (31) presented comorbidities; 27% (126) experienced pain after the ending of the episode, with an average duration of 138.7 days. In general, diagnosis was done late, making it difficult to use antivirals correctly. The presence of pain was more frequent than reported in other publications, however there are few data in this age group.

Vaccination impact: mortality and time shift to COVID-19 maximum severity in hospitalized patients. An Argentine multicenter registry.

INTRODUCTION: The COVID-19 vaccine became an effective instrument to prevent severe SARS-CoV-2 infections. However, 5% of vaccinated patients will have moderate or severe disease. OBJECTIVE: to compare mortality and days between the symptom onset to the peak disease severity, in vaccinated vs. unvaccinated COVID-19 hospitalized patients. METHODS: Retrospective observational study in 36 hospitals in Argentina. COVID-19 adults admitted to general wards between January 1, 2021, and May 31, 2022 were included. Days between symptoms onset to peak of severity were compared between vaccinated vs. unvaccinated patients with Cox regression, adjusted by Propensity Score Matching (PSM). Results in patients with one and two doses were also compared. RESULTS: A total of 3663 patients were included (3001 [81.9%] unvaccinated and 662 [18%] vaccinated). Time from symptom onset to peak severity was 7 days (IQR 4-12) vs. 7 days (IQR 4-11) in unvaccinated and vaccinated. In crude Cox regression analysis and matched population, no significant differences were observed. Regarding mortality, a Risk Ratio (RR) of 1.51 (IC95% 1.29-1.77) was observed in vaccinated patients, but in the PSM cohort, the RR was 0.73 (IC95% 0.60-0.88). RR in patients with one COVID-19 vaccine dose in PSM adjusted population was 0.7 (IC95% 0.45-1.03), and with two doses 0.6 (IC95% 0.46-0.79). DISCUSSION: The time elapsed between the onset of COVID-19 symptoms to the highest severity was similar in vaccinated and unvaccinated patients. However, hospitalized vaccinated patients had a lower risk of mortality than unvaccinated patients.

Introducción: A pesar de la eficacia de la vacuna contra el COVID-19 el 5% de los pacientes vacunados presentaran una enfermedad moderada o grave. El objetivo del presente estudio fue comparar los días entre el inicio de los síntomas y la gravedad máxima de la enfermedad, en pacientes con COVID-19 vacunados vs. no vacunados. Métodos: Estudio observacional retrospectivo en 36 hospitales de Argentina. Se incluyeron adultos con COVID-19 hospitalizados entre el 1/01/2021 y 31/5/2022. Se recolectaron datos demográficos, comorbilidades y progresión clínica de la enfermedad. Se compararon los días entre el inicio de los síntomas y el pico de gravedad entre vacunados y no vacunados mediante regresión de Cox, ajustada por emparejamiento por Propensity Score Matching (PSM). En un análisis de subgrupos, se compararon los resultados en pacientes con una y dos dosis de vacuna. Resultados: Se incluyeron 3663 pacientes (3001 [81.9%] no vacunados y 662 [18%] vacunados). El tiempo transcurrido desde el inicio de los síntomas hasta el pico de gravedad fue de 7 días (IQR 4 - 12) en no vacunados, y de 7 días (IQR 4-11) en vacunados. Tanto en el análisis de regresión de Cox crudo como en el ajustado, no se observaron diferencias significativas entre ambos grupos (HR ajustado 1.08 [IC 95% 0.82-1.4; p = 0.56]). En cuanto a la mortalidad, el Riesgo Relativo (RR) fue 1.51 (IC95% 1.29-1.77) en los pacientes vacunados, pero en la cohorte ajustada por Propensity Score, el RR fue de 0.73 (IC95% 0.60-0.88). El RR en el grupo con una dosis de vacuna COVID-19 en el análisis PSM fue 0.7 (IC95% 0.45-1.03), y con dos dosis 0.6 (IC95% 0.46-0.79). Discusión: El tiempo entre el inicio de los síntomas de COVID-19 y el pico de severidad fue igual en vacunados y no vacunados. Sin embargo, los pacientes vacunados hospitalizados presentaron menor mortalidad tras el ajuste por confundidores.

[Physicians' views and perspectives on advanced directives in patients with incipient dementia]. / Posición y perspectivas de los médicos sobre las directivas anticipadas en pacientes con demencia incipiente.

Dementia is a progressive disease in which patients lose their ability to decide and communicate. Advance directives (AD) allow patients to express their preferences on end of life care in the early stages of the disease. Primary care practitioners (PCP) are in the best position to promote AD. The aim of this study was to elicit PCPs views about the discussion of AD with early stage dementia patients. A qualitative approach was taken, focus groups and individual interviews to elderly patients' PCPs from the Hospital italiano de buenos aires were conducted. A purposive sampling was performed, conforming homogeneous groups according to age and seniority. The discussion was stimulated by a vignette. We performed thematic content analysis in an interdisciplinary team. Twelve PCPs = 30 year of age, 32 middle-aged and 8 over 45 years participated of the study. The youngest group favored the discussion of AD while those over 45 regarded the family as the decision maker, and thus, the discussion as useless. Besides, they expressed that our society is not mature enough to discuss AD. Difficulties in AD implementation, in predicting the evolution of a patient's disease, the span of time between the discussion and AD implementation, lack of legislation and specific institutional policies were other factors that conditioned the discussion. Younger PCPs expressed concern on the lack of communication skills and difficulties to broach this subject with patients. PCPs perspectives on AD vary, their age should be taken into account when designing strategies to their implementation.

Spanish Revised Memory and Behavior Problems Checklist Scale (SpRMBPC): trans-cultural adaptation and validation of the RMBPC questionnaire.

BACKGROUND: The use of standardized scales is critical for monitoring the interventions within and between different populations, but the current Spanish tools are dispersed in several scales. A simple tool for simultaneously and exhaustively evaluating patient's symptoms and caregiver's distress in Spanish-speaking groups is needed. METHODS: RMBPC was translated into Spanish by cross-cultural adaptation. Comprehensibility and easiness of SpRMBPC were evaluated with 92 patient-caregiver dyads. Reliability, stability and scale structure were evaluated by Cronbach's α, test-retest and factor analysis respectively. Concurrent and discriminant validity were assessed by correlation with validated tools for measuring stage of dementia; memory, disruptive behaviors and depression symptoms of the patients; and anxiety, depression and burden of the caregivers (CDR, MMSE, NPIq, NPI disruption, NPI depression, HADS-A; HADS-D and Zarit Burden Interview respectively). RESULTS: Almost all caregivers completed the questionnaire (97% completeness; 7.5% missing data). Both the frequency of Patient's Symptoms and Caregiver Reaction scores and subscores displayed high stability and reliability. All of these scores correlated positively with their respective validated tools as predicted, except with MMSE. The patients' subscores for Disruptive Behaviors and Memory Impairment displayed their highest correlation with the disruptive symptoms and level of dementia validated tools. CONCLUSIONS: SpRMBPC is a validated tool for assessing the dementia stage and the psychiatric morbidity of patients and caregivers. The Frequency Disruption and Memory subscales assess specifically patient's disruptive symptoms and dementia stages. These tools can be applied to analyze the burden of the patient's disease and the caregiver's distress in Spanish-speaking populations.

[Descriptive analysis of 4776 patients admitted to medical clinic services for COVID-19. Results of the Argentine Multi-Center Registry - REMA-COVID-19]. / Análisis descriptivo de 4776 pacientes internados en servicios de clínica médica por COVID-19. Resultados del Registro Multicéntrico Argentino - REMA-COVID-19.

A multicenter registry that included adults hospitalized for COVID-19 was carried out in various provinces of Argentina, from March to October 2020. The objectives were to describe the epidemiological characteristics, clinical manifestations, treatments, complications and risk factors, need for admission to critical care units and mortality. The registry included information on 4776 patients in 37 health centers in Argentina. Of them, 70.2% came from the city of Buenos Aires and from Buenos Aires Province; 52.3% were men. The mean age was 56 years (SD 20.3). Of them, 13.1% stated that they were health personnel. The median time of symptoms at the time of hospitalization was 3 days (CI 1-6). The most frequent comorbidities were hypertension in 32.4% and diabetes mellitus in 15.8%. The most frequent symptoms were: cough 58%, odynophagia 23.3%, myalgia 20.5% and fever / low-grade fever 19.9%. The hospital stay had a median of 8 days (CI 4-15). A 14.8% of the patients required critical care, while 3.2% who also required it, were not transferred to a closed unit due to adequacy of the therapeutic effort. The most frequent complications in critical care were: cardiovascular events (54.1%), septic shock (33.3%), renal failure (9.7%) and pneumonia associated with mechanical ventilation (12.5%). Overall mortality was 12.3%. Old age, dementia and COPD behaved as independent predictors of mortality (p < 0.001, 0.007 and 0.002 respectively) in the multivariate analysis.

Se realizó un registro multicéntrico que incluyó personas adultas internadas por COVID-19 en varias provincias de la Argentina, desde marzo a octubre de 2020. Los objetivos fueron describir las características epidemiológicas, manifestaciones clínicas, tratamientos, complicaciones y factores de riesgo, necesidad de admisión a unidades de cuidados críticos y mortalidad. El registro incluyó información de 4776 pacientes, en 37 centros de salud de Argentina. El 70.2% provenían de la ciudad de Buenos Aires y la provincia de Buenos Aires. El 52.3% eran hombres. La media de edad fue de 56 años (DE 20.3). Un 13.1% de pacientes manifestó ser personal de salud. La mediana de tiempo de síntomas al momento de la internación fue de 3 días (IC 1-6). Las comorbilidades más frecuentes fueron hipertensión arterial en 32.4% y diabetes mellitus en 15.8%. Los síntomas más frecuentes fueron: tos 58%, odinofagia 23.3%, mialgias 20.5% y fiebre/febrícula 19.9%. La estadía hospitalaria tuvo una mediana de internación de 8 días (IC 4-15). El 14.8% de los pacientes requirió cuidados críticos, en tanto que el 3.2%, que también lo requería, no pasó a unidad cerrada por adecuación del esfuerzo terapéutico. Las complicaciones más frecuentes en cuidados críticos fueron: eventos cardiovasculares (54.1%), shock séptico (33.3%), insuficiencia renal (9.7%) y neumonía asociada a la ventilación mecánica (12.5%). La mortalidad global fue del 12.3%. La edad avanzada, demencia y EPOC se comportaron como predictores independientes de mortalidad (p < 0.001, 0.007 y 0.002 respectivamente) en el análisis multivariado.

[Delirium in elderly inpatients. An 18 month follow-up]. / Delirium en ancianos hospitalizados. Seguimiento de 18 meses.

Delirium usually hardens care during hospitalization and increases morbidity during hospital stay and after discharge. The objective of this study was to describe the prevalence of delirium in elderly inpatients in a Buenos Aires hospital, its morbidity and mortality during hospital stay and the next 18 month follow-up. Patients aged 70 or older admitted to internal medicine unit between September 2005 and May 2006 were enrolled. Delirium was assessed with the Spanish version of Confusion Assessment Method. Demographic data, cause of admition and length of stay, destination after discharge and mortality were registered. A new evaluation was made 18 months after discharge. We evaluated 194 patients and 74 were excluded. Of the 120 included, 52 (43.3%) presented delirium. We found significant differences between patients with and without delirium in previous placement in nursing home (17.3% vs. 1.5%; p < 0.002), dementia (40.4% vs. 8.8%; p < 0.001), median activity of daily living (5 vs. 6; p < 0.001), length-of-stay (7 vs. 5; p = 0.04) and mortality rate (21.2% vs. 1.5%; p < 0.001). Evaluation 18 months later showed differences between patients with and without delirium in median of activity of daily living (1/6 vs. 5/6), patients living in nursing homes (27.5% vs. 7.9%), estimated survival 35.3% (CI 95%: 24-49%) at day 569 and 49% (CI 95%: 32.9-65.4%) at day 644. The difference between survival curves was statistically significant (p = 0.027). Delirium increases morbidity and mortality during hospital stay. Elderly with delirium are at risk of worsening disability and of becoming dependent after discharge and it is a risk factor for higher mortality during the following months after discharge.

[A multidisciplinary program for the treatment and follow up of depression in ambulatory elderly]. / Ensayo pragmático para evaluar la efectividad de un programa de manejo de depresión para pacientes mayores de 65 años en un Plan de Salud.

Depression is a common disorder in the elderly population; with significant elevated rates in terms of morbidity and mortality. Nonetheless it continues to be a subdiagnosticated disease with poor outcomes due to lack in the effectiveness of follow up. We developed collaborative intervention programs for elderly people in primary care at Hospital Italiano de Buenos Aires designing a randomized controlled trial in the ambulatory setting. Patients were recruited for an initial comprehensive geriatric evaluation, and then randomly assigned to the program intervention (n=18) or usual care (n=19). At 6 months, 55.5% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline compared with 31.5% of those on usual care. Although the reduction of the outcomes of depressive symptoms is not statistically significative, these are preliminary data. We believe there is a trend toward better results with regard to improvements in depressive symptoms in patients in the intervention group, and that this will achieve statistical significance as the number of subjects recruited is increased in the course of the trial.
