Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Endocarditis IV: Nursing Management

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Endocarditis I: Introduction

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...

Healthcare Associated Infections II: Preventive Measures

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Summary

External ventricular drainage (EVD) infections are common. Prolonged drainage and frequent cerebrospinal fluid (CSF) sampling increase infection risk, suggesting a need for protocol changes to minimize complications.

Area of Science:

Neurosurgery
Infectious Disease Epidemiology
Critical Care Medicine

Background:

External ventricular drainage (EVD) is a critical neurosurgical procedure for managing elevated intracranial pressure by draining cerebrospinal fluid (CSF).
EVD-related infections, such as meningitis and ventriculitis, represent a significant complication, impacting patient outcomes.
Understanding the etiological factors behind EVD infections is crucial for developing effective preventative strategies.

Purpose of the Study:

To retrospectively analyze the incidence and potential causes of external ventricular drainage (EVD)-related infections in a single-center cohort.
To identify specific risk factors associated with the development of EVD-related infections, including meningitis and ventriculitis.
To inform the development of improved EVD management protocols to reduce infection rates.

Main Methods:

A retrospective study involving 228 patients who underwent external ventricular drainage between January 1993 and April 2005.
Review and comparison of patient demographics, disease characteristics, EVD management details, and infection occurrence.
Application of risk-analysis, including multivariate analysis, to identify significant predictors of EVD-related infections.

Main Results:

A substantial infection rate of 23.2% was observed among patients with external ventricular drainage.
Duration of EVD drainage exceeding 11 days was identified as a significant risk factor for infection (OR 4.1, p = 0.001).
Frequent cerebrospinal fluid (CSF) sampling was also significantly associated with an increased risk of infection (OR 0.2, p = 0.003).

Conclusions:

The study highlights a high incidence of external ventricular drainage-related infections.
Multivariate analysis confirmed that prolonged drainage duration and frequent CSF sampling are key risk factors.
A revised EVD protocol is proposed to mitigate infection risks and improve patient safety.
