Bacteremia nosocomial, también conocida como bacteriemia nosocomial. Potencial para la prevención de casos
JAMA
|June 20, 1977
Resumen
La bacteriemia adquirida en la comunidad y la bacteriemia nosocomia son preocupaciones significativas, y las vías respiratorias y urinarias son lugares comunes de infección. Se necesita más investigación para prevenir las infecciones adquiridas en el hospital, ya que muchos casos persisten a pesar de las directrices actuales.
Área de la Ciencia:
- Enfermedades infecciosas Enfermedades infecciosas.
- Epidemiología de los hospitales.
- Microbiología Microbiología.
Sus antecedentes:
- La bacteriemia, una infección del torrente sanguíneo, es una complicación grave en pacientes hospitalizados.
- La distinción entre bacteriemia adquirida en la comunidad y bacteriemia nosocomia (hospitalaria) es crucial para estrategias efectivas de manejo y prevención.
Objetivo del estudio:
- Analizar la incidencia, los sitios comunes y los organismos causantes de la bacteriemia adquirida en la comunidad y la bacteriemia nosocomial.
- Investigar la contribución de los procedimientos médicos a la bacteriemia nosocomia e identificar áreas para futuras investigaciones.
Principales métodos:
- Análisis retrospectivo de la bacteriemia en pacientes hospitalizados durante un período de seis meses.
- Identificación y categorización de la bacteriemia en función de la fuente de adquisición (comunidad vs. nosocomial).
- Análisis de sitios de infección, microorganismos aislados y asociación con dispositivos/terapias médicas.
Principales resultados:
- Se identificaron 187 casos de bacteriemia adquirida en la comunidad y 91 casos de bacteriemia nosocomial.
- Las vías respiratorias y urinarias fueron los sitios de infección más comunes para ambos tipos.
- Escherichia coli fue una causa principal en ambas categorías; Staphylococcus aureus y Klebsiella también fueron frecuentes en las infecciones nosocomiales.
- 32 de los 91 casos nosocomiales estaban relacionados con catéteres urinarios, terapia respiratoria / intravenosa o hiperalimentación.
Conclusiones:
- La bacteriemia nosocomial sigue siendo un desafío significativo, con una proporción notable vinculada a las intervenciones médicas.
- Incluso con una adhesión óptima a las directrices actuales, todavía se produciría un número sustancial de casos bacteriémicos, lo que pone de relieve la necesidad de nuevas estrategias de prevención.
- La investigación adicional es esencial para desarrollar métodos más efectivos para prevenir las infecciones adquiridas en el hospital y la posterior bacteremia.

01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:17Transmission-based Precautions I: Contact, Enteric, and Droplets
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

01:29Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
