Abstract

Insights

Acinetobacter baumannii infections in Jakarta hospitals are linked to ventilator use in the ICU and urinary catheters in wards. Most strains were multidrug-resistant, but all remained susceptible to colistin.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Hospital Epidemiology

Background:

  • Acinetobacter baumannii is a multidrug-resistant Gram-negative bacterium causing nosocomial infections.
  • Risk factors for Acinetobacter baumannii infections have been previously documented.
  • Understanding specific associations in different hospital settings is crucial for infection control.

Purpose of the Study:

  • To investigate the association between Acinetobacter baumannii positive cultures and invasive procedures in hospitalized patients.
  • To identify specific risk factors for Acinetobacter baumannii acquisition in Intensive Care Units (ICU) and Internal Medicine Wards (IMW).

Main Methods:

  • A retrospective, 1:1 matched case-control study was conducted.
  • Data from in-patients in an ICU and IMW in Jakarta from 2015-2018 were analyzed.
  • Acinetobacter baumannii positive cultures were compared with multi-sensitive bacteria controls.

Main Results:

  • A significant association was found between Acinetobacter baumannii positive culture and ventilator use in the ICU (p=0.039).
  • Urinary catheter use in the IMW showed a significant association with Acinetobacter baumannii positive culture (p=0.022).
  • Multivariate analysis indicated that length of stay in the ICU was also associated with Acinetobacter baumannii positive culture.

Conclusions:

  • Ventilator use in ICUs and urinary catheters in IMWs are significant risk factors for Acinetobacter baumannii positive cultures.
  • All identified Acinetobacter baumannii isolates demonstrated susceptibility to colistin.
  • These findings highlight the importance of targeted infection control measures based on invasive procedures.

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...

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.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

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...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...
