    Depresión y autopercepción de la carga del cuidado en pacientes en hemodiálisis y sus cuidadores
    (2011) Arechabala, Maria Cecilia; Isabel Catoni, Maria; Palma, Eugenia; Barrios, Silvia
    OBJETIVO: Determinar síntomas depresivos, apoyo social percibido y autopercepción de carga en pacientes en hemodiálisis crónica (HDC); identificar síntomas depresivos y grado de fatiga en cuidadores de pacientes en HDC, y evaluar -en el paciente- la asociación entre autopercepción de carga y apoyo social percibido, y entre autopercepción de carga y síntomas depresivos, y -en el cuidador- la relación entre el número de años de cuidado y el grado de fatiga alcanzado. MÉTODOS: Se tomó una muestra de 162 díadas paciente-cuidador, a quienes se les aplicaron los instrumentos "escala adaptada de percepción de apoyo social", "escala de autopercepción de carga", "escala de depresión del Centro de Estudios Epidemiológicos" y "escala de severidad de la fatiga". Los instrumentos fueron aplicados a los pacientes por ayudantes de investigación entrenados y, en el caso de los cuidadores, fueron autoaplicados. RESULTADOS: Del total de pacientes, 40 por ciento fueron mujeres, con un promedio de edad de 56 ± 14,9 años, mientras que entre los cuidadores principales, 75 por ciento fueron mujeres, cónyuges, con una edad promedio de 50 ± 16,1 años. Se observó que tanto los pacientes (40,74 por ciento) como los cuidadores principales (43,82 por ciento) presentaban síntomas de depresión. Se encontró una asociación positiva (r = 0,43, P 0,001) entre la autopercepción de carga y la presencia de síntomas depresivos en los pacientes. CONCLUSIONES: Los cuidadores principales son en su mayoría mujeres y familiares de los pacientes. Se perciben fatigados con el cuidado, al igual que lo perciben los propios pacientes. La presencia de síntomas depresivos es similar en pacientes y cuidadores, y hay una asociación estadísticamente significativa entre autopercepción de carga y presencia de síntomas depresivos en los pacientes.(AU)

    Nurses' workload in hemodialysis units
    (SOC MEDICA SANTIAGO, 2017) Barrios, Silvia; Isabel Catoni, Maria; Cecilia Arechabala, Maria; Palma, Eugenia; Ibacache, Yolanda; Richard, Joanna
    Background: Knowing nurses' workload in hemodialysis units allows a better organization of human resources. Aim: To determine nurses' workload according to dependence and risk profiles of patients undergoing chronic hemodialysis. Material and Methods: One hundred fifty one patients from five hemodialysis units were selected and categorized in terms of dependence and risk using the instrument "Care according to dependence and risk in hemodialysis (CUDYR-DIAL). Nurses' activities for direct and indirect care and the time taken to complete those activities were measured. Results: Per patient, nurses used 36.5 +/- 10.7 min for direct and 23.6 min for indirect care. The time required for direct care of patients at high risk with partial dependence and at high risk and partial self-sufficiency was 41.2 and 40.3 minutes respectively. Conclusions: During a dialysis session, nurses occupy 60% of their time providing direct care, mainly directed to patients categorized as being of high risk-partial dependence and high risk-partial self-sufficiency.

    Sleep duration and fatigue in construction workers: A preliminary study
    (2021) Ferrada, Ximena; Barrios, Silvia; Masalan, Patricia; Campos-Romero, Solange; Carrillo, Juan; Molina, Yerko
    The construction industry is known for its high rate of accidents. Among the different possible causes of this situation, we could find lack of sleep and fatigue. Chronic sleep deprivation is a determining factor in the deterioration of vigilance and alert, and consequently a risk factor for occupational accidents. Fatigue is the answer of our organism to sustained physical and mental stress. Regretfully, those topics have been ovelooked in the construction industry. The objective of this study is to understand better these phenomena, such as sleep duration and fatigue, and whether they are interrelated, and to propose strategies to mitigate them and contribute to the reduction of accidents in construction projects. We worked with 154 male construction workers from one Chilean construction company. To assess sleep quality, we used the Pittsburgh Sleep Quality Index (PSQI). To evaluate fatigue, we used a personal computer version of the Psychomotor Vigilance Test (PC-PVT) that measures alertness and vigilance. This 5-minute test was performed on construction workers on-site in the morning. Those people who took part in the test were classified into various groups according to self-reported sleep hours, namely: 7–9 h (26%), 5–7 h (61.7%), and <5 h (12.3%). These results were compared for three variables (Mean Reaction Time (RT), 10% faster, and 10% slower) using an Analysis of Variance (ANOVA) test. Differences were found for Mean RT and Slowest 10%, the difference being greater in the group that reported sleeping <5 h, but without statistical significance. Studies with a greater number of subjects and measurements are required throughout the working day.

    Spanish validation of the "self-perception of burden of care scale"
    (UNIV FED SAO PAULO, DEPT ENFERMAGEN, 2012) Arechabala, Maria Cecilia; Catoni, Maria Isabel; Barrios, Silvia; Palma, Eugenia
    Objective: To validate the Spanish language version of the broad "self-perception of burden of care scale" by Cousineau et al. Methods: The sample consisted of 161 patients undergoing chronic hemodialysis at five dialysis centers in the city of Santiago - Chile. This scale was translated into Spanish and a pilot test was conducted with ten patients; after this procedure, we developed the final instrument to be subjected to the validation process. Results: The reliability of the scale was stable, with fluctuations of the Cronbach's alpha coefficient of 0.903 and 0.915; we decided therefore to maintain the 25 original items within the Spanish version. Conclusion: The overall reliability of the instrument was 0.91, very close to that obtained in the original version (0.93).
