Introduction and objectives: Determinants of chronic obstructive pulmonary disease (COPD) in the early stages of its natural history are not well known. Improving our knowledge of these factors will help to design interventions that can modify prognosis. Study objectives are: a) to characterize a COPD population of young adults aged 35-50 years from a multidimensional point of view; b) to compare these patients with smokers with normal lung function: and c) to create a cohort of young adults aged 35-50 years (smokers or former smokers), with and without COPD, who will be followed in the future to improve understanding of the natural history of the disease. Participants and method: This is a case-control multicenter study aimed at establishing a well characterized cohort of young adults, smokers or former-smokers, with and without COPD, for subsequent follow-up. A total of 311 participants (101 cases and 210 controls) were selected from approximately 30 primary care settings and 12 hospitals in 8 Spanish regions. Subjects were smokers or former smokers (> 10 pack-years) aged 35-50 years. Diagnosis of COPD was based on a post-bronchodilator result of FEV1/FVC < 70%. The main study variables were: questionnaires on health, symptoms, exacerbations and daily physical activity, lung function tests, blood and sputum samples, and low-dose computed tomography. In the statistical analysis, COPD patient characteristics will be described and compared with control subjects using a logistic regression analysis. (C) 2018 SEPAR.

Resumen Introduccion y objetivos Los determinantes en fases iniciales de la historia natural de la enfermedad pulmonar obstructiva cronica (EPOC) son poco conocidos. Entenderlos mejor es de capital importancia para poder disenar intervenciones dirigidas a modificar su pronostico. Los principales objetivos del estudio son: a) caracterizar a una poblacion de adultos jovenes con EPOC de forma multidimensional; b) comparar estos pacientes con sujetos fumadores con funcion pulmonar normal; y c) establecer una cohorte de adultos jovenes con y sin EPOC, que pueda ser seguida a largo plazo para conocer mejor la historia natural de la enfermedad. Participantes y metodo EARLY COPD es un estudio multicentrico de casos y controles que permitira establecer una cohorte de sujetos para su seguimiento posterior. Se seleccionaron 311 (101 casos y 210 controles) participantes reclutados en una treintena de centros de atencion primaria y 12 hospitales de 8 comunidades autonomas espanolas. Los participantes eran fumadores o exfumadores (> 10 paquetes ano) de entre 35-50 anos de edad. Los casos presentaban una espirometria obstructiva con un FEV1/FVC

ObjetivoBuscar oportunidades de mejora mediante la evaluación de la atención domiciliaria que ofrecen los equipos de atención primaria en nuestro entorno a las personas > 65 años de edad con enfermedades crónicas. Identificar cuáles son las variables del paciente y del servicio que recibe que se asocian con el deterioro funcional y cognitivo, ingreso en una residencia geriátrica, visita a urgencias, ingreso hospitalario o muerte.DiseñoEstudio analítico de seguimiento de una cohorte durante 3 años.EmplazamientoEquipos de atención primaria de Cataluña.ParticipantesEn total, 1.300 pacientes > 65 años con enfermedades crónicas incluidos en el Programa de Atención Domiciliaria.Mediciones principalesSe recoge anualmente su estado de salud (Charlson, Barthel, Pfeiffer, Braden y Gijón), datos sobre el cuidador (Zarit), atenciones recibidas (social y sanitaria), salud subjetiva (SF-12), visitas a urgencias, ingresos temporales y el resultado final: muerte, ingreso en residencies geriátricas u hospital. Los análisis principales se basarán en regresiones logísticas y una análisis de supervivencia.DiscusiónEl estudio permitirá identificar las características del paciente que tengan valor pronóstico, así como conocer las prácticas de atención social y sanitaria que se asocian con una mejor supervivencia y un menor consumo de recursos sociosanitarios.ObjectivesTo evaluate home care by primary care teams for people over 65 years old with chronic conditions, in order to identify improvement opportunities.To identify patient and care variables associated with cognitive and functional impairment, nursing home admission, attendance at casualty units, hospital admission and death.DesignAnalytic study of the follow-up of a cohort for 3 years.SettingPrimary health care teams in Catalonia, Spain.PatientsOne thousand three hundred patients over 65 with chronic pathologies and cared for by home care programmes in Catalonia.Main measurementsThe following will be recorded annually: health status (Charlson, Barthel, Pfeiffer, Braden, and Gijón), data on the carer (Zarit), care received (social and health), self-perception of health (SF-12), Casualty attendance, short-term admissions and the final results, i.e. death or definitive admission to a nursing home or hospital. The statistical analyses will be based on logistic regression and a survival analysis.ConclusionsThe study should reveal patient characteristics with prognostic value, as well as identify the social and health factors related to better survival and lower consumption of health and social resources.

Background The purpose of this study is to identify which variables –among those commonly available and used in the primary care setting– best predict mortality in a cohort of elderly dependent patients living at home (EDPLH) that were included in a home care program provided by Primary Care Teams (PCT). Additionally, we explored the risk of death among a sub-group of these patients that were admitted to hospital the year before they entered the home care program. Methods A one-year longitudinal cohort study of a sample of EDPLH patients included in a home care programme provided by 72 PCTs. Variables collected from each individual patient included health and social status, carer’s characteristics, carer’s burden of care, health and social services received. Results 1,001 patients completed the study (91.5%), 226 were admitted to hospital the year before inclusion. 290 (28.9%) died during the one-year follow-up period. In the logistic regression analysis women show a lower risk of death [OR= 0.67 (0.50-0.91)]. The risk of death increases with comorbidity [Charlson index OR= 1.14 (1,06-1.23)], the number of previous hospital admissions [OR= 1,16 (1.03-1.33)], and with the degree of pressure ulcers [ulcers degree 1–2 OR = 2.94 (1.92-4.52); ulcers degree 3–4 OR = 4.45 (1.90-10.92)]. The logistic predictive model of mortality for patients previously admitted to hospital identified male sex, comorbidity, degree of pressure ulcers, and having received home care rehabilitation as independent variables that predict death. Conclusions Comorbidity, hospital admissions and pressure ulcers predict mortality in the following year in EDPLH patients. The subgroup of patients that entered home care programs with a previous record of hospital admission and a high score in our predictive model might be considered as candidates for palliative care.

Objective: To identify the characteristics of chronic patients and their environment in order to predict the nursing workload required 1 year after their inclusion in a home care program. Methods: A longitudinal study was carried out in 72 primary health care teams in Catalonia (Spain) with a 1-year follow-up of 1,068 home care patients over 64 years old. The variables collected from each patient included data on health and social status (Charlson and Barthel indexes and the Pfeiffer, Braden and Gijon scales), carer overburden (Zarit scale), hospital admissions, use of emergency services, self-perceived health (SF-12) and the number of health worker visits. Results: Patients received 7.2 (SD 10.4) visits per year from their nurse-in-charge, out of a total of 8.7 (SD 13.1) nursing visits per year. Risk factors for receiving more nursing visits at home were male gender (IRR = 1.42, 95%CI: 1.20-1.67), dependency for daily activities (IRR = 1.65, 95%CI: 1.29-2.13), decubitus ulcers (IRR = 4.03, 95%CI: 2.27-7.14) and receiving emergency medical care at home (IRR = 1.65, 95%CI: 1.31-2.07). In contrast, patients with major cognitive impairment (IRR = 0.78, 95%CI: 0.63-0.98) had a lower probability of receiving nursing visits at home. Conclusions: Workload can be predicted by patients’ clinical characteristics. The positive correlation of workload with variables related to disease severity and the negative correlation with variables related to cognitive impairment show that home care nursing in Catalonia is basically demand-oriented.
