ABSTRACT
Resumen Introducción: No hay criterios establecidos para distinguir las flebitis de causa infecciosa de las no infecciosas. Objetivo: Evaluar el impacto de un programa de intervención en la tasa de flebitis de tipo infecciosa (asociada a bacteriemia sin otro foco o pus local) y no infecciosa (el resto). Pacientes y Métodos: Estudio intervencional en tres etapas: diagnóstico de situación basal, intervención y evaluación. Resultados: Se detectaron 10 casos de flebitis infecciosa y 186 no infecciosas. Las flebitis infecciosas disminuyeron con la intervención (0,2 a 0,04 eventos por 1.000 días camas; p = 0,02) pero no las no infecciosas (2,3 a 2,3 por 1.000 días camas). Cinco casos con flebitis infecciosa tuvieron bacteriemia, uno de ellos con endocarditis y reemplazo valvular y otro con shock séptico y desenlace fatal. Ninguno de los casos en el grupo no infeccioso se complicó o falleció. Las flebitis infecciosas se presentaron más tarde que las otras (4,1 versus 2,4 días; p = 0,007) y se asociaron a fiebre (40% vs 5,9%, p = 0,004). Las flebitis no infecciosas se asociaron al uso de compuestos irritantes (OR 6,1; IC95 1,3-29, p < 0,05). Conclusiones: El programa demostró un impacto favorable para disminuir sólo las flebitis de tipo infecciosa. La distinción parece ser relevante porque las infecciosas se asocian a fiebre, complicaciones o letalidad, parecen responder a programas de prevención y son más tardías.
Background: There is no consensus definition to distinguish infectious from non-infectious phlebitis associated to peripheral venous catheter. Aims: To evaluate the impact of an intervention program on the rate of infectious (those associated to bacteremia or local purulent discharge) and non-infectious phlebitis (the rest) and identify differential features. Methods: Interventional study developed in three stages: basal measurement, intervention, and evaluation. Results: Ten infectious and 186 non-infectious phlebitis were registered. Infectious phlebitis diminished after intervention (0.2 to 0.04 events per 1,000 bed-days; p = 0.02) but not the rest (2.3 per 1,000 bed-days before and after). Five of 10 patients with infectious phlebitis had bacteremia, one with infectious endocarditis and valve replacement, and other with septic shock and a fatal outcome. None of the patients in the non-infectious group presented complications. Infectious phlebitis appeared later (mean 4.1 versus 2.4 days; p = 0.007) and were associated to fever (40% vs 5.9%, p = 0.004). Non-infectious phlebitis was associated to irritating compounds (OR 6.1; IC95 1.3-29, p < 0.05). Conclusions: The intervention program demonstrated a favorable impact only on the rate of infectious phlebitis. Distinction appears to be relevant because those of infectious origin are associated with fever, complications or death, respond to an intervention program, and emerge lately.

PURPOSE: A retrospective tertiary care center-based study was undertaken to evaluate the visual outcome in Eales' disease, based on a new classification system, for the first time. MATERIALS AND METHODS: One hundred and fifty-nine consecutive cases of Eales' disease were included. All the eyes were staged according to the new classification: Stage 1: periphlebitis of small (1a) and large (1b) caliber vessels with superficial retinal hemorrhages; Stage 2a: capillary non-perfusion, 2b: neovascularization elsewhere/of the disc; Stage 3a: fibrovascular proliferation, 3b: vitreous hemorrhage; Stage 4a: traction/combined rhegmatogenous retinal detachment and 4b: rubeosis iridis, neovascular glaucoma, complicated cataract and optic atrophy. Visual acuity was graded as: Grade I 20/20 or better; Grade II 20/30 to 20/40; Grade III 20/60 to 20/120 and Grade IV 20/200 or worse. All the cases were managed by medical therapy, photocoagulation and/or vitreoretinal surgery. Visual acuity was converted into decimal scale, denoting 20/20=1 and 20/800=0.01. Paired t-test / Wilcoxon signed-rank tests were used for statistical analysis. RESULTS: Vitreous hemorrhage was the commonest presenting feature (49.32%). Cases with Stages 1 to 3 and 4a and 4b achieved final visual acuity ranging from 20/15 to 20/40; 20/80 to 20/400 and 20/200 to 20/400, respectively. Statistically significant improvement in visual acuities was observed in all the stages of the disease except Stages 1a and 4b. CONCLUSION: Significant improvement in visual acuities was observed in the majority of stages of Eales' disease following treatment. This study adds further to the little available evidences of treatment effects in literature and may have effect on patient care and health policy in Eales' disease.
