Impact of one year of pandemic on Spanish Intensive Care Units / Impacto de un año de pandemia en las Unidades de Cuidados Intensivos de España

Objective. To measure the impact of the pandemic inSpanish ICUs.Material and methods. On-line survey, conducted inApril 2021, among SEMICYUC members. Participants wereasked about number of patients admitted, increase in thenumber of beds and staff, structures created in the hospitaland self-assessment of the work performed.Results. We received 246 answers from 157 hospitals.67.7% of the ICUs were expanded during the pandemic, overall increase in beds of 58.6%. The ICU medical staff increasedby 6.1% and there has been a nursing shortage in 93.7% ofunits. Patients exceeded 200% the pre-pandemic ICU capacity.In 88% of the hospitals the collaboration of other specialistswas necessary. The predominant collaboration model consisted of the intensive care medicine specialist being responsiblefor triage and coordinating patient management. Despite that53.2% centres offered training for critical care, a deteriorationin the quality of care was perceived. 84.2% hospitals drew upa Contingency Plan and in 77.8% of the hospitals a multidisciplinary committee was set up to agree on decision-making.Self-evaluation of the work performed was outstandingand 91.9% felt proud of what they had achieved, however, upto 15% considered leaving their job.Conclusions. The Spanish ICUs assumed an unprecedented increase in the number of patients. They achieved it withouthardly increasing their staff and, while intensive care medicinetraining was carried out for other specialists who collaborated.The degree of job satisfaction was consistent with pre-pandemic levels.

Objetivo. Medir el impacto de la pandemia COVID-19 en las UCI españolas. Material y métodos. Cuestionario online, realizado en abril 2021 entre socios de SEMICYUC. Se interrogó acerca delnúmero de pacientes ingresados, incremento en número decamas y personal, estructuras creadas en el hospital y autoevaluación del trabajo realizado.Resultados. Recibimos 246 respuestas de 157 hospitales. El 67.7% de las UCI se expandieron durante la pandemia,con un incremento de camas del 58.6%. El personal médicode las UCI aumentó un 6.1% y hubo escasez de enfermería enel 93.7% de las unidades. Los pacientes excedieron un 200%la capacidad pre-pandemia y en el 88% de los hospitales fuenecesaria la colaboración de otros especialistas, siendo elmodelo predominante aquel en que el especialista en medicina intensiva era responsable del triaje y coordinaba el tratamiento del paciente. A pesar de que en el 53.2% de los centros se ofreció formación en medicina intensiva se detectó undeterioro de la calidad asistencial. El 84.2% de los hospitaleselaboraron un plan de contingencia y el 77.8% conformaronun comité multidisciplinar para consensuar decisiones. Laevaluación del trabajo fue sobresaliente y el 91.9% se sienteorgulloso del resultado, pero hasta el 15% consideró abandonar la especialidad.Conclusiones. Las UCI españolas asumieron un incremento de pacientes sin precedentes, sin apenas aumento delpersonal y mientras formaban a otros especialistas que colaboraron. El grado de satisfacción con el trabajo realizado fuesimilar al pre-pandemia. (AU)

Sustained high serum malondialdehyde levels are associated with severity and mortality in septic patients.

INTRODUCTION: There is a hyperoxidative state in sepsis. The objective of this study was to determine serum malondialdehyde (MDA) levels during the first week of follow up, whether such levels are associated with severity during the first week and whether non-surviving patients showed higher MDA levels than survivors during the first week. METHODS: We performed an observational, prospective, multicenter study in six Spanish Intensive Care Units. Serum levels of MDA were measured in 328 patients (215 survivors and 113 non-survivors) with severe sepsis at days one, four and eight of diagnosis, and in 100 healthy controls. The primary endpoint was 30-day mortality and the secondary endpoint was six -month mortality. The association between continuous variables was carried out using Spearman's rank correlation coefficient. Cox regression analysis was applied to determine the independent contribution of serum MDA levels on the prediction of 30-day and 6-month mortality. Hazard ratio (HR) and 95% confidence intervals (CI) were calculated as measures of the clinical impact of the predictor variables. RESULTS: We found higher serum MDA in septic patients at day one (p < 0.001), day four (p < 0.001) and day eight (p < 0.001) of diagnosis than in healthy controls. Serum MDA was lower in surviving than non-surviving septic patients at day one (p < 0.001), day four (p < 0.001) and day eight (p < 0.001). Serum MDA levels were positively correlated with lactic acid and SOFA during the first week. Finally, serum MDA levels were associated with 30-day mortality (HR = 1.05; 95% CI = 1.02-1.09; p = 0.005) and six-month mortality (hazard ratio (HR) = 1.05; 95% CI = 1.02-1.09; p = 0.003) after controlling for lactic acid levels, acute physiology and chronic health evaluation (APACHE)-II, diabetes mellitus, bloodstream infection and chronic renal failure. CONCLUSIONS: To our knowledge, this is the largest series providing data on the oxidative state in septic patients to date. The novel finding is that high serum MDA levels sustained throughout the first week of follow up were associated with severity and mortality in septic patients.
