Planificación anticipada de los cuidados y del uso de recursos hospitalarios en pacientes con COVID-19 en un programa de atención integrada para adultos mayores frágiles en residencias / Advance care planning and use of health resources among COVID-19 nursing home patients in an integrated health care program for frail elders

Objetivos: Evaluar la magnitud y la trascendencia de un proceso de estratificación y planificación anticipada de los cuidados y el uso de recursos hospitalarios en pacientes con COVID-19 en un programa de atención integrada para pacientes adultos mayores frágiles en residencias. Material y métodos: Estudio de cohorte prospectiva de pacientes >64 años con COVID-19 en un programa en residencias, desde marzo a septiembre de 2020. Se evaluó la identificación de pacientes con necesidad de abordaje paliativo (NECPAL positivo), la realización de la planificación anticipada del cuidado y su registro visible en la historia clínica electrónica. Se evaluó la utilización de cuidados intensivos. Resultados: Trescientos setenta y cuatro pacientes tuvieron COVID-19: el 88% eran mujeres, mediana de edad 88 años. El 79% tenían necesidades de abordaje paliativo, de los cuales el 68% tenía registrada la planificación anticipada del cuidado (p<0,001) en su historia clínica electrónica. Solamente el 1% de los pacientes con necesidad de abordaje paliativo con criterios de severidad utilizó cuidados intensivos. La mortalidad global fue del 25%. De los fallecidos, el 74% tenían criterios de severidad (p<0,001) y el 90% tenían necesidad de abordaje paliativo (p<0,001). Conclusiones: Realizar un proceso de atención basado en la estratificación e identificación de pacientes con necesidad de abordaje paliativo y la planificación anticipada del cuidado, con registro en un lugar central y visible de la historia clínica electrónica, podría mejorar la calidad y la seguridad de la atención, adecuando los recursos a las necesidades del paciente en todo momento y especialmente en situaciones de emergencia sanitaria.

Objectives: To estimate the magnitude and importance of a process of stratification and advance care planning and the use of health resources, among patients in an integrated health care program for frail elderls in nursing homes,that were referred to the hospital with COVID-19. Material and methods: Prospective cohort study of patients >64 years old with COVID-19 infection, in a health care program in nursing homes (from 3/15/2020 to 9/15/2020). The identification of patients with palliative needs, the performing and visible registration in electronic health records of the advance care planning and the use of intensive care were assessed. Results: We included 374 COVID-19 patients. 88% were women, the median age was 88 years old. The 79% were patients with palliative needs, of which 68% had the advance care planning (P<.001) registered in the electronic health record. Only 1% of patients with palliative needs and severity criteria were admitted to the intensive care unit. Overall mortality was 25%. Of those who died, 74% had severity criteria (P<.001) and 90% had palliative needs (P<.001). Conclusions: Carrying out a care process based on identification of patients with palliative needs and advance care planning and a central and visible registration of advance care planning in health records, could improve the quality and safety of care and optimize the use of intensive care health resources at all times and especially in public health emergencies.

Monitoreo serológico y psicológico en personal de salud durante el comienzo de la pandemia COVID-19 / Serological and psychological monitoring of healthcare workers during the start of the COVID-19 pandemic

Introducción: el personal de salud (PdS) es esencial en la lucha contra el COVID-19. Al inicio de la pandemia, el riesgo de adquirir la enfermedad en este grupo era desconocido. Buscamos estimar incidencia y prevalencia de anticuerpos anti-SARS-CoV-2, y prevalencia de burnout en una cohorte de PdS durante la pandemia COVID-19, así como valorar la prevalencia de burnout y depresión en la cohorte. Materiales y métodos: cohorte prospectiva conformada por médicos que atendían pacientes COVID-19 desde marzo de 2020 hasta enero de 2021, en un hospital de alta complejidad de la ciudad de Buenos Aires. Se evaluó IgM e IgG anti-SARS-CoV-2 quincenalmente durante 3 meses, así como la presencia de síntomas compatibles y factores asociados a la exposición. Se remitió a participantes con alteraciones de la esfera psíquica a contacto con el equipo de salud mental del hospital. Resultados: se incluyeron 52 participantes; de ellos, 31 eran mujeres; mediana de edad 32 años (rango 25-58). La mediana de horas semanales de trabajo autoinformadas fue 48 (IIC [intervalo intercuartil] 40-69,5). Inicialmente todos fueron PCR SARS-CoV-2 negativos en hisopado nasal; 11 (21,50% IC 95%; 9,62-32,53%) tuvieron COVID-19 sintomático con anticuerpos positivos. Los factores con mayor asociación a riesgo de COVID-19 fueron anosmia/disgeusia OR 403,33 (IC 95%; 47,60-3417,02), fiebre OR 172,53 (IC 95%; 28,82-1032,65), mialgias OR 41,97 (IC 95%; 8,08-217,84), conviviente con COVID-19 OR 28,17 (IC 95%; 5,67-179,97). Cerca del 40% presentaba alteraciones en las escalas de medición de burnout o depresión. Discusión: la incidencia hallada coincide con las cifras informadas acerca de personal de salud en la etapa inicial de la pandemia en la Argentina. Otro aspecto similar fue una mayoría de infecciones de curso leve, sin ningún paciente hospitalizado. No obstante, se halló una elevada incidencia de alteraciones de la esfera psíquica, tanto al comienzo como al final del seguimiento. Conclusiones: la incidencia de positivización de anticuerpos anti-SARS-CoV-2 fue cercana al 20%. No evidenciamos infecciones presintomáticas o asintomáticas. En cambio, la prevalencia de burnout y depresión fue elevada. La salud mental es un componente del personal de salud que debe ser priorizado en situaciones futuras de impacto similar. (AU)

Introduction: healthcare personnel are essential in the response against COVID-19. At the beginning of the pandemic the risk of acquiring the disease in this group was unknown. We sought to estimate incidence and prevalence of anti SARS-CoV-2 antibodies, as well as burnout prevalence in a cohort of healthcare staff during the pandemic, as well as assessing the prevalence of burnout and depression in this group. Materials and methods: prospective cohort formed by physicians tending to COVID-19 patients from march 2020 to january 2021 in a high-complexity hospital in the city of Buenos Aires. We evaluated anti SARS-CoV-2 IgM and IgG each 15 days for 3 months as well as the presence of compatible symptoms and factors associated to exposition to the virus. Patients showing signs of burnout and/or depression were referred to proper care by the mental health team in the hospital. Results: we included 52 patients, 31 women, median age was 32 years (range 25 - 58). Median amount of self-reported hours worked each week was 48 (IQR 40 - 69.5). Initially all participants had a negative COVID-19 PCR nasopharyngeal swab; 11 (21.50% CI95% 9.62 - 32.53%) had symptomatic COVID-19 with positive antibodies. Factors showing stronger association with testing positive were anosmia/dysgeusia OR 403.33 (CI95% 47.60-3417.02), fever OR 172.53 (CI95% 28.82 - 1032.65), myalgia OR 41.97 (CI95% 8.08 - 217.84), cohabitation with confirmed COVID-19 case OR 28.17 (CI95% 5.67 - 179.97). Near 40% showed alterations in burnout or depression scales. Discussion: the incidence rate we found was like reported values in the initial stages of the pandemic in Argentina. Another similarity was that all cases were mild; no hospitalization was required for any participant. We found an elevated incidence of alterations in the psychic sphere, both at the beginning and end of the follow up period. Conclusions:the incidence of positive SARS-CoV-2 antibodies was around 20%. No pre or asymptomatic cases were identified. Burnout and depression incidence was high. Mental health is a component that should never be overlooked in similar situations to come. (AU)

[Epidemiology of patients with hepatocellular carcinoma in a University hospital]. / Epidemiología de pacientes con hepatocarcinoma en un Hospital Universitario.

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies. The aim of this study is to characterize and describe epidemiologically patients with diagnosis of hepatocellular carcinoma in the Italian Hospital of Buenos Aires during a 12-year period. Overall survival for our cohort was 58%, 46%, and 36% at 1, 3 and 5 years respectively. Average survival for patients receiving palliative treatment was 5 months, while for those who received either non-curative or curative treatment was 23 and 75 months respectively. Recurrence-free survival for those patients who underwent a curative treatment was 89%, 76% y 61% at 1, 3 and 5 years. A thorough analysis of etiology, risk factors, incidence, mortality and treatment was made. The study's importance lies in its large sample size, quantity and quality of data, and will most certainly stimulate the development of local studies in hepatocellular carcinoma.

A diferencia de otros tumores de alta prevalencia, la evidencia científica acerca del HCC se limita principalmente a pequeñas cohortes y estudios retrospectivos. El objetivo de este estudio fue describir epidemiológicamente a aquellos pacientes con diagnóstico de HCC en el Hospital Italiano de Buenos Aires en un periodo de 12 años. La supervivencia global para nuestra cohorte fue de 58, 46 y 36% a 1, 3 y 5 años respectivamente. El promedio de supervivencia en pacientes con tratamiento paliativo fue de 5 meses, 23 para aquellos que recibieron tratamientos no curativos y 75 meses para los que recibieron tratamientos curativos. El porcentaje de pacientes libres de enfermedad a 1, 3 y 5 años fue de 89%, 76% y 61% respectivamente. Se realizó un estudio minucioso de la etiología, factores de riesgo, incidencia, mortalidad y tratamientos realizados. Su importancia yace en su tamaño muestral, calidad y cantidad de información disponible.

Tromboprofilaxis en pacientes hospitalizados: implementación de un programa multifacético / Thromboprophylaxis in hospitalized patients: implementation of a multifacetical program

Resumen La enfermedad tromboembólica venosa es la causa prevenible más frecuente de muerte hospitalaria. A pesar de contar con evidencia y recomendaciones sobre la utilidad de la tromboprofilaxis, la adherencia por parte de los médicos a las mismas es muy variable, y frecuentemente subóptima. El objetivo de este estudio fue evaluar un programa institucional con estrategias multifacéticas dirigido a médicos, sobre tromboprofilaxis en internación y estimar el cambio en la adecuación de la tromboprofilaxis antes y después de la intervención. La intervención se mantuvo durante 6 años, fue múltiple, utilizando acciones pasivas como car telería, y activas, como educación médica continua, confección y adopción de una guía institucional de práctica clínica y un sistema de soporte informático para la decisión clínica. La adecuación basal de la tromboprofilaxis mejoró de 59% a 82% después de la intervención y se mantuvo en el tiempo. La mejora en la adecuación se asoció a una reducción de los sangrados mayores, en particular en pacientes intervenidos quirúrgicamente.

Abstract Venous thromboembolic disease is the most common preventable cause of hospital death. Despite the existence of evidence of the usefulness of thromboprophylaxis and recommendations, adherence by physicians to them is highly variable, and frequently suboptimal. The objective was to evaluate the change in the adequacy of thromboprophylaxis before and after an intervention on thromboprophylaxis with multifaceted strategies for physicians. The intervention was a 6 years institutional program with multiple strategies: passive actions such as posters and active actions as continuous medical education, adaptation of an institutional clinical practice guide and a computerized clinical decision support system. The baseline adequacy of thromboprophylaxis improved from 59% to 82% and was maintained over time. The improvement in fitness was associated with a reduction in major bleeding, particularly in patients undergoing surgery.

Criterios de Beers para identificar el consumo de medicación potencialmente inapropiada: adaptación para su aplicación en Argentina / Beers criteria to identify the consumption of potentially inappropriate medication: adaptation for its application inArgentina

Introducción. Los Criterios de Beers son los más utilizados para evaluar el uso de medicación potencialmente inapropiada en grandes poblaciones, pero no contemplan algunos medicamentos de uso frecuente fuera de los EE.UU. Objetivo. Realizar una adaptación al contexto de Argentina de los Criterios de Beers publicados en 2019. Métodos. Fue elaborada una lista preliminar de medicación potencialmente inapropiada adaptada a la comercialización local, que luego fue consensuada por un panel de expertos (método Delphi). Resultados. De los 112 medicamentos originales listados en la tabla dos de los Criterios de Beers (en forma individual o como grupo), fueron excluidos 36 por no estar disponibles el país y fueron sumados 23 que no se comercializan en los EE.UU. pero sí en Argentina. Luego de dos rondas y de consensuar la suma a esta lista de dos grupos farmacológicos(antimigrañosos y vasodilatadores periféricos), fue acordado el agregado de picosulfato, bisacodilo, senósidos y cáscara sagrada como medicación potencialmente inapropiada en el grupo de agentes contra el estreñimiento, la fluoxetina entre los inhibidores selectivos de la recaptación de serotonina y el Ginkgo biloba como droga contra la demencia. También hubo consenso en advertir el riesgo de hipotensión ortostática asociado a la tamsulosina, en aconsejar la consideración de la carga anticolinérgica total del esquema terapéutico administrado y en recomendar al paracetamol como primera línea de tratamiento del dolor, asociado o no a opioides. Conclusiones. Contar con una versión de los Criterios de Beers 2019 adaptada al contexto de Argentina contribuirá al desarrollo y monitoreo de intervenciones para prevenir y reducir el consumo de medicación potencialmente inapropiada.

Introduction.The Beers Criteria is the most widely used criteria to assess the use of potentially inappropriate medication in large populations, but they do not include some medications that are frequently used outside the United States. Objective.To make an adaptation of the Beers Criteria published in 2019 to the context of Argentina. Methods. A preliminary list of potentially inappropriate medication adapted to local market and practice was designed, which was then agreed upon by a panel of experts (Delphi method). Results. Of the 112 original drugs in the table 2 of the Beers Criteria (individually or as a group), 36 were excluded because they were not available in Argentina and 23 locally marketed drugs but not in the US were included. After two rounds and agreeing to add two additional pharmacological groups to this list (antimigraine and peripheral vasodilators), it was decided to add picosulfate, bisacodyl, sennosides and cascara sagrada as potentially inappropriate medication in the group of anti-constipation agents, fluoxetine among. the selective serotonin reup take inhibitors and Ginkgo biloba as an anti-dementia drug. There was also consensus in warning about the risk of orthostatic hypotension associated with tamsulosin,in advising consideration of the total anticholinergic load of the therapeutic regimen administered, and in recommending paracetamol as the first line of pain treatment, associated or not with opioids. Conclusions. Having a version of the Beers Criteria 2019 adapted to the Argentine context will contribute to the development and monitoring of interventions to prevent and reduce the consumption of potentially inappropriate medication.

In-Hospital Mortality and Glycemic Control in Patients with Hospital Hyperglycemia.

BACKGROUND: Stress-induced hyperglycemia is a phenomenon that occurs typically in patients hospitalized for acute disease and resolves spontaneously after regression of the acute illness. However, it can also occur in diabetes patients, a fact that is sometimes overlooked. It is thus important to make a proper diabetes diagnosis if hospitalized patients with episodes of hyperglycemia with and without diabetes are studied. AIMS: To estimate the extent of the association between stress-induced hyperglycemia and in-hospital mortality in patients with hospital hyperglycemia (HH), and to explore potential differences between patients diagnosed with diabetes (HH-DBT) and those with stress-induced hyperglycemia (SH), but not diagnosed with diabetes. METHODS: A cohort of adults with hospital hyperglycemia admitted to a tertiary, university hospital in Buenos Aires, Argentina, was analyzed retrospectively. RESULTS: In the study, 2,955 patients were included and classified for analysis as 1,579 SH and 1,376 HH-DBT. Significant differences were observed in glycemic goal (35.53% SH versus 25.80% HH-DBT, p < 0.01), insulin use rate (26.66% SH versus 46.58% HH-DBT, p < 0.01), and severe hypoglycemia rate (1.32% SH versus 1.74% HH-DBT, p < 0.01). There were no differences in hypoglycemia rate (8.23% SH versus 10.53% HH-DBT) and hospital mortality. There was no increase in risk of mortality in the SH group adjusted for age, non-scheduled hospitalization, major surgical intervention, critical care, hypoglycemia, oncological disease, cardiovascular comorbidity, and prolonged hospitalization. CONCLUSIONS: In this study, we observed better glycemic control in patients with SH than in those with HH-DBT, and there was no difference in hospital mortality.

Morphologic Variations in the Circle of Willis as a Risk Factor for Aneurysm Rupture in the Anterior and Posterior Communicating Arteries.

BACKGROUND: Intracranial aneurysms are acquired abnormal vascular dilations. The most dangerous complication of a cerebral aneurysm is its rupture, with a high rate of mortality. This study aimed to determine whether there is an association between anatomic variations in the circle of Willis and ruptured aneurysms in the anterior and posterior communicating arteries. METHODS: A cross-sectional study of adult patients with a diagnosis of intracranial aneurysm was carried out between March 2015 and March 2019. The patients were divided into groups of ruptured or unruptured aneurysm in the anterior and posterior communicating arteries. RESULTS: A total of 132 patients with anterior and posterior communicating artery aneurysms were included. The presence of anatomic variation in the circle of Willis presented a statistically significant association with ruptured aneurysms (odds ratio [OR], 2.28; 95% confidence interval [CI], 1.11-4.65; P = 0.024). There was a statistically significant difference between the presence of nonspherical aneurysm and rupture (OR, 6.9; 95% CI, 3.12-15.48; P < 0.0001). Multivariate logistic regression observed smoking (OR, 2.4; 95% CI, 1.01-5.9; P = 0.4), anterior complex variations (OR, 2.68; 95% CI, 1.01-7.18; P < 0.04), and nonspherical morphology (OR, 4.7; 95% CI, 1.93-11.45; P = 0.001) presented a statistically significant association with the rupture. CONCLUSIONS: Our results suggest that the studied variations of the circle of Willis and nonspherical morphology, in addition to playing a role in the development of cerebral aneurysms, may contribute to their rupture.

Baseline Functional Status and One-year Mortality After Hospital Admission in Elderly Patients: a prospective cohort study.

INTRODUCTION: Hospitalization represents a major factor that may precipitate the loss of functional status and the cascade into dependence. The main objective of our study was to determine the effect of functional status measured before hospital admission on survival at one year after hospitalization in elderly patients. METHODS: Prospective cohort study of adult patients (over 65 years of age) admitted to either the general ward or intensive Care units (ICU) of a tertiary teaching hospital in Buenos Aires, Argentina. Main exposure was the pre-admission functional status determined by means of the modified "VIDA" questionnaire, which evaluates the instrumental activities of daily living. We used a multivariate Cox proportional hazards model to estimate the effect of prior functional status on time to all-cause death while controlling for measured confounding. Secondarily, we analyzed the effect of post-discharge functional decline on long-term outcomes. RESULTS: 297 patients were included in the present study. 12.8% died during hospitalization and 86 patients (33.2%) died within one year after hospital discharge. Functional status prior to hospital admission, measured by the VIDA questionnaire (e.g., one point increase), was associated with a lower hazard of all-cause mortality during follow-up (Hazard Ratio [HR]: 0.96; 95% Confidence Interval [CI]: 0.94-0.98). Finally, functional decline measured at 15 days after hospital discharge, was associated with higher risk of all-cause death during follow-up (HR: 2.19, 95% CI: 1.09-4.37) Conclusion: Pre-morbid functional status impacts long term outcomes after unplanned hospitalizations in elderly adults. Future studies should confirm these findings and evaluate the potential impact on clinical decision-making.

Introducción: La hospitalización representa un factor que puede favorecer la pérdida de la funcionalidad. El objetivo principal de este estudio fue determinar el efecto de la funcionalidad previa a la admisión hospitalaria sobre la sobrevida al año del egreso, en pacientes adultos mayores. Métodos: Este estudio de cohorte prospectiva incluyó pacientes de 65 años o mayores que fueron hospitalizados en la sala general o la unidad de terapia intensiva en un hospital universitario de la ciudad de Buenos Aires, Argentina. La funcionalidad basal fue medida a través del cuestionario VIDA modificado, el cual evalúa las actividades instrumentales de la vida diaria. Utilizamos un modelo multivariable de Cox para estimar el efecto de la funcionalidad basal sobre la sobrevida al año posterior al egreso, el cual permitió ajustar por potenciales confundidores. Además, analizamos el efecto de la funcionalidad luego del egreso hospitalario sobre la mortalidad al año del mismo. Resultados: Se incluyeron 297 pacientes, de los cuales 12.8% fallecieron durante la hospitalización, y 86 pacientes (33.2%) fallecieron dentro del año del egreso hospitalario. Un aumento de un punto en la escala de la funcionalidad basal (es decir, mejor funcionalidad), se asoció a una disminución en el riesgo de muerte al año del egreso (Hazard Ratio [HR]: 0.96; Intervalo de confianza [IC] 95%: 0.94­0.98). Por ultimo, la declinación funcional posterior al egreso hospitalario se asoció a un mayor riesgo de muerte durante el seguimiento (HR: 2.19, IC 95%: 1.09­4.37). Conclusión: La funcionalidad previa a la hospitalización de los adultos mayores impacta en los resultados a largo plazo luego de una hospitalización.

Association between non-attendance to outpatient clinics and emergency department consultations, hospitalizations and mortality in a Health Maintenance Organization.

BACKGROUND: Non-attendance to scheduled medical appointments in outpatient clinics is a problem that affects patient health and health-care systems. OBJECTIVE: Evaluate association of non-attendance to scheduled appointments in outpatient clinics and Emergency Department (ED) visits, hospitalizations and mortality. METHODS: Retrospective cohort study of outpatients enrolled in 2015 to 2016 in the Hospital Italiano de Buenos Aires HMO with over five scheduled appointments. Individual non-attendance proportion was obtained by dividing missed over scheduled appointment numbers in the 365 days prior to index date. Outcomes were evaluated with a Cox proportional-hazards or Fine and Gray model for competing risks. We adjusted by several variables. RESULTS: Sixty-five thousand two hundred sixty-five adults were included. Mean age was 63.6 years (SD 18.16), 29.9% male. Outpatients had average 10.18 (SD 5.59) appointments. Non-attendance the year before the index appointment had a median of 20%. A 10% increase in non-attendance was significantly associated with ED visits (asHR 1.19; 95%CI 1.08-1.32, P < .001) and all-cause mortality (aHR 7.57; 95%CI 4.88-11.73, P < .001). In the matched subcohort analysis we observed a crude significant association of non-attendance with ED visits (P < .001) and all-cause mortality (P < .001). DISCUSSION: Our findings show non-attendance could be a marker of health events that lead to emergency department evaluations and/or death.

Impact of anticoagulants in elderly patients who suffer a hip fracture. Should we have a different approach?

INTRODUCTION: Hip fracture in the elderly is a frequent problem. Chronic treatment with anticoagulants is common in these patients, and may delay surgery. OBJECTIVES: To compare time to surgery, hospital stay, in-hospital and 90 days complications between anticoagulated (A) and non-anticoagulated (NA) groups. METHODS: Retrospective cohort of >64 years-old patients with acute hip fracture. Period June-2014 to December 2019. We estimated crude and adjusted OR (95%CI) for in-hospital complications with logistic regression model. We report the crude and adjusted HR for readmission and 90-day mortality with Cox proportional hazards model. RESULTS: Of the 1058 patients, 123 (11%) were anticoagulated. Time to surgery was 26.4 hours (IIQ 13.9-48) in A and 24 hours (IIQ 2.3-48) in NA, p0.001. Hospital stay was 7 days (IIQ 5-9) in A and 6 days (IIQ 5-10.5) NA, p0,000. In-hospital complications were 17 (14%) in A and 81 (9%) in NA, p0.064. The adjusted OR was 1.53 (95%CI 0.8-2.7) p0.138. For 90-day readmission, the crude HR was 1.51 (95%CI 0.99-2.29) p0.053 and the adjusted HR was 1.31 (95%CI 0.85-2.00) p0,09. For 90-day mortality, the crude HR was 0.80 (95%CI 0.45-1.43) p0.464 and the adjusted HR was 0.70 (95% CI 0.39-1.25) p0.239. DISCUSSION: While we found differences between groups in time to surgery and hospital statistics, their clinical relevance should be reviewed.

Causes of appointment attendance, nonattendance, and cancellation in outpatient consultations at a university hospital.

BACKGROUND: Nonattendance to scheduled appointments in outpatient clinics is a frequent problem in ambulatory medicine with an impact on health systems and patients' health. The characterization of nonattendance is fundamental for the design of appropriate strategies for its management. AIMS: To identify causes of nonattendance of scheduled ambulatory medical appointments by adult patients. METHODS: Case and two controls study nested in a prospective cohort. A telephone-administered questionnaire was applied within the first 72 hours to identify the causes of attendance, nonattendance, or cancellation in patients who had a scheduled appointment to which they had been present, absent, or cancelled. RESULTS: A total of 150 absences (cases), 176 attendances, and 147 cancellations (controls) in a prospective cohort of 160 146 scheduled appointments (2012/2013) were included. According to self-reports in telephone interviews, the most frequent causes of nonattendance were forgetting 44% (66), unexpected competing events 15.3% (23), illness or unwellness 12% (18), work-related inconvenience 5.3% (8), transport-related difficulties 4.7% (4), and cause that motivated appointment scheduling already resolved 4.7% (4). DISCUSSION: The main cause of nonattendance is forgetting the scheduled appointment, but there is a proportion of different causes that do not respond to reminders but could respond to different strategies.

Tasa de reinternaciones y factores asociados en ancianos luego de una internación por fractura de cadera / Rate of re-experiences and associated factors in the elderly after hospitalization due to hip fracture

INTRODUCCIÓN: El anciano con fractura de cadera tiene alto riesgo de complicaciones y mortalidad hospitalaria. Las estadías hospitalarias cortas y el alta temprana con problemas clínicos activos pueden llevar a reinternaciones. OBJETIVOS: conocer la tasa de reinternaciones, los motivos y las variables predictoras de las mismas en los sujetos que tuvieron fracturas de cadera. MÉTODOS: Se trabajó una cohorte retrospectiva. Se incluyó a todos los pacientes ingresados en el Registro Institucional de Ancianos con Fractura de Cadera entre julio de 2014 y julio de 2017. Se describió la tasa de reinternación y su IC95%. Se utilizó un modelo de riesgo proporcional de Cox para describir factores de riesgo y el tiempo a la reinternación. RESULTADOS: Se incluyó a 858 pacientes. La mediana de días de internación fue de 6 (rango intercuartil [RIC 5-9]). El 86% (737) de los pacientes era de sexo femenino, con una mediana de edad de 86 años (RIC 81-89). La tasa de reinternación a los 30 días fue de 10% (IC95%: 8,3-12,5) y al año, de 39% (IC95%: 34,8-42,6). La principal causa fue la infección (30%). Los factores asociados fueron: edad (>85 años) Razón de Hazard o Hazard ratio (HR)1,3 (IC95%: 1-1,7; p 0,03), sexo femenino HR 0,5 (IC95%: 0,4-0,7; p<0,01), fragilidad HR 1,4 (IC95%: 1,1-1,8; p<0,01), score de Charlson (≥2) HR 1,6 (IC95%: 1,3-2,1; p<0,01), días de internación (>7 días) HR 1,4 (IC95%: 1,2-1,9; p<0,01). CONCLUSIONES: La reinternación después de una fractura de cadera tiene alta incidencia. El cuidado perioperatorio de los pacientes con fractura de cadera es esencial para reducir las complicaciones.

INTRODUCTION: Elderly patients with hip fracture are at high risk for complications and in-hospital mortality. Short hospital stay and early discharge with still active clinical problems may lead to readmissions. OBJECTIVES: to know the rate of readmissions, the reasons and the predictive variables in patients who had hip fractures. METHODS: A retrospective cohort study was performed, with all patients included in the institutional registry of elderly patients with hip fracture between July 2014 and July 2017. Readmission rates and their CI95% were described. A proportional risk Cox model was used to describe risk factors and time-toreadmission. RESULTS: A total of 858 patients were included with a median hospital stay of 6 days (interquartile range [IQR] 5-9), 86% (737) of female patients and a median age of 86 years (IQR 81-89). Readmission rates were 10% (CI95%: 8.3-12.5) at 30 days and 39% (CI95%: 34.8-42.6) at 12 months. The main cause was infection (30%). Associated factors were: age (>85 years) HR 1.3 (CI95%: 1-1.7; p 0.03), female gender HR 0.5 (CI95%: 0.4-0.7; p<0.01), fragility HR 1.4 (CI95%: 1.1-1.8; p<0.01), Charlson score (≥2) HR 1.6 (CI95%: 1.3-2.1; p<0.01), hospital stay (>7 days) HR 1.4 (CI95%: 1.2- 1.9, p<0.01). CONCLUSIONS: Readmission after hip fracture has a high incidence. Perioperative care of patients with hip fracture is essential to reduce complications.

Analysis of Postoperative Complications in Spinal Surgery, Hospital Length of Stay, and Unplanned Readmission: Application of Dindo-Clavien Classification to Spine Surgery.

STUDY DESIGN: Retrospective study. Level of evidence III. OBJECTIVE: Postoperative complications in spine surgery are associated with increased morbidity, hospital length of stay, and health care costs. Registry of complications in orthopedics and the spine surgery is heterogeneous. METHODS: Between July 2016 and June 2017, 274 spinal surgeries were performed, the presence of postoperative complications was analyzed at 90 days (according to the classification of Dindo-Clavien, grades I-V), hospital length of stay, surgical complexity (low, medium, and high), unplanned readmission, and risk factors were evaluated. RESULTS: A total of 79 patients suffered a complication (28.8%), of them 21 (26.7%) were grade I, 24 (30.3%) were grade II, 4 (5.7%) were grade IIIA, and 29 (37.3%) were grade IIIB. There were no IV and V grade cases. The most frequent complication was excessive pain followed by deep wound infection and anemia. Surgical complexity and surgical time were significantly associated with the risk of developing a complication. The average number of hospital length of stay in patients without and with complications were 2.7 and 10.6, respectively, and the unplanned readmission rate was 11%. CONCLUSIONS: Registry of postoperative complications allows the correct standardization and risk factors required to establish measures to decrease them, the application of Dindo-Clavien classification was useful for the purpose of our study.
