Impact of intensive care unit admission during handover on mortality: propensity matched cohort study.

OBJECTIVE: To investigate the impact of intensive care unit admission during medical handover on mortality. METHODS: Post-hoc analysis of data extracted from a prior study aimed at addressing the impacts of intensive care unit readmission on clinical outcomes. This retrospective, single-center, propensity-matched cohort study was conducted in a 41-bed general open-model intensive care unit. Patients were assigned to one of two cohorts according to time of intensive care unit admission: Handover Group (intensive care unit admission between 6:30 am and 7:30 am or 6:30 pm and 7:30 pm) or Control Group (intensive care unit admission between 7:31 am and 6:29 pm or 7:31 pm and 6:29 am). Patients in the Handover Group were propensity-matched to patients in the Control Group at a 1:2 ratio. RESULTS: A total of 6,650 adult patients were admitted to the intensive care unit between June 1st 2013 and May 31st 2015. Following exclusion of non-eligible participants, 5,779 patients (389; 6.7% and 5,390; 93.3%, Handover and Control Group) were deemed eligible for propensity score matching. Of these, 1,166 were successfully matched (389; 33.4% and 777; 66.6%, Handover and Control Group). Following propensity-score matching, intensive care unit admission during handover was not associated with increased risk of intensive care unit (OR: 1.40; 95%CI: 0.92-2.11; p=0.113) or in-hospital (OR: 1.23; 95%CI: 0.85-1.75; p=0.265) mortality. CONCLUSION: Intensive care unit admission during medical handover did not affect in-hospital mortality in this propensity-matched, single-center cohort study.

RESUMO Objetivo: Avaliar o impacto na mortalidade da admissão em unidade de terapia intensiva durante passagem de plantão médico. Métodos: Análise post-hoc de estudo original publicado previamente, com o objetivo de avaliar os impactos da readmissão em unidade de terapia intensiva nos desfechos clínicos. Este estudo de coorte retrospectivo, em centro único, com pareamento por escore de propensão, foi conduzido em uma unidade de terapia intensiva geral, aberta, com 41 leitos. Com base no tempo de internação na unidade de terapia intensiva, os pacientes foram categorizados em duas coortes: Grupo Passagem de Plantão (admissão entre 6h30 e 7h30 ou 18h30 e 19h30) ou Grupo Controle (internação entre 7h31 e 18h29 ou 19h31 e 6h29). Pacientes no Grupo Passagem de Plantão foram pareados com Grupo Controle na proporção de 1:2. Resultados: Entre 1° de junho de 2013 e 31 de maio de 2015, 6.650 pacientes adultos foram admitidos na unidade de terapia intensiva. Após a exclusão de participantes inelegíveis, 5.779 pacientes (389; 6,7% no Grupo de Admissão na Passagem de Plantão e 5.390; 93,3% no Grupo de Controle) foram elegíveis para pareamento por escore de propensão, dos quais 1.166 foram pareados com sucesso (389; 33,4% no Grupo Passagem de Plantão e 777; 66,6% no Grupo Controle). Após pareamento, admissão na unidade de terapia intensiva durante a passagem plantão não foi associada ao aumento da chance de óbito na unidade de terapia intensiva (RC: 1,40; IC95%: 0,92-2,11; p=0,113) ou no hospital (RC: 1,23; IC95%: 0,85-1,75; p=0,265). Conclusão: Internação em unidade de terapia intensiva durante passagem de plantão médico não impactou na mortalidade hospitalar.

Acute kidney injury due to excessive and prolonged intramuscular injection of veterinary supplements containing vitamins A, D and E: A series of 16 cases / Daño renal agudo debido a inyección intramuscular excesiva y prolongada de suplementos veterinarios con vitaminas A, D y E: serie de 16 casos

Background: Despite well-documented risks, injectable supplements containing high doses of vitamins are commonly used. Objectives: To describe acute kidney injury (AKI) as a complication of vitamin intoxication. Methods: Our series consisted of 16 patients with kidney complications resulting from the use of veterinary intramuscular injection supplements of vitamin A, D and E. The patients were admitted to two referral hospitals in Fortaleza (Brazil) between January 2010 and January 2015. Results: Patients’ mean age was 28.3±8.9 years (19-53 years), and 11 (68.7%) were male. Main signs and symptoms upon admission were nausea (68.7%), vomiting (62.5%), weight loss (43.7%), epigastric pain (31.2%) and headache (31.2%). At hospital admission the mean laboratory values were: hemoglobin 10±2.0g/dL (6.1-14.2), leukocytes 10,542 ± 4871/mm3 (4100-5,100), creatinine 3.9 ± 5.2mg/dL (0.7-22) and urea 91 ± 88mg/dL (22-306), respectively. Serum calcium was 12 ± 2.2 mg/dL (8.8-15.5), 24-h urine calcium was 575 ± 329 mg (10.7-1058), serum PTH was 55 ± 141pg/mL (2-406), and serum vitamin D concentration was 135 ± 75ng/mL (22-265). Using KDIGO criteria, AKI was diagnosed in 13 patients (81.2%), classified as stage 1 (n = 3), stage 2 (n = 3) or stage 3 (n = 7). No deaths occurred in the study period. Conclusions: Excessive use of veterinary vitamin supplements containing high doses of vitamin A, D and E was associated with AKI. Hypercalcaemia, which was a common finding, appears to be a contributing factor to the development of this type of AKI (AU)

Antecedentes: Suplementos inyectables que contienen altas dosis de vitaminas son utilizados con frecuencia, a pesar de los riesgos bien documentados. Objetivo: Describir la ocurrencia de daño renal agudo (IRA) como complicación de intoxicación por suplementos vitamínicos. Métodos: Esta es una serie de 16 pacientes con complicaciones renales resultantes de la utilización de inyección intramuscular de suplementos veterinarios con vitaminas A, D y E. Los pacientes fueron ingresados en 2 hospitales de referencia en Fortaleza (Brasil), entre enero de 2010 y enero de 2015. Resultados: La edad media de los pacientes fue de 28,3 ± 8,9 años (19-53 años) y 11 (68,7%) eran varones. Signos y síntomas principales al ingreso fueron náuseas (68,7%), vómitos (62,5%), pérdida de peso (43,7%), dolor epigástrico (31,2%) y cefalea (31,2%). Al ingreso en el hospital los valores medios de laboratorio fueron: hemoglobina 10 ± 2,0g/dL (6,1+14,2), leucocitos 10.542 ± 4.871/mm3 (4.100-15.100), creatinina 3,9 ± 5,2mg/dL (0,7-22) y urea 91 ± 88mg/dL (22-306), respectivamente. El nivel de calcio sérico fue de 12 ± 2,2 mg/dL (8,8-15,5), el de calcio en orina de 24 h fue de 575 ± 329 mg (10,7-1.058), el de PTH sérico fue de 55 ± 141 pg/mL (2-406) y el nivel de vitamina D sérica fue de 135 ± 75 ng/mL (22-265). Utilizando criterios KDIGO, se diagnosticó IRA en 13 pacientes (81,2%); fueron clasificadas como clase 1 (n = 3), clase 2 (n = 3) y clase 3 (n = 7). No hubo muertes en el período de estudio. Conclusiones: El uso excesivo de suplementos vitamínicos veterinarios que contienen altas dosis de vitamina A, D y E se asoció con IRA. La hipercalcemia, un hallazgo común, parece ser un factor que contribuye al desarrollo de este tipo de IRA (AU)
