Nosocomial Infections : Causes, Risk Factors & Prevention
Nosocomial Infections: Causes, Risks & Prevention | insrn.com
Nosocomial infections, or hospital-acquired infections (HAIs), are a major concern in healthcare settings, necessitating strict infection control measures.
Nosocomial infections are infections acquired by patients during their hospital stay or within 14 days after discharge. These infections are caused by bacteria, viruses, or fungi present in healthcare environments.
- Poor hygiene and sanitation practices
- Overcrowded wards and clinics
- Indiscriminate use of broad-spectrum antibiotics
- Prolonged hospital stays and surgical procedures
- Use of indwelling medical devices (e.g., catheters, ventilators)
- Staphylococcus aureus (including MRSA)
- Escherichia coli (E. coli)
- Pseudomonas aeruginosa
- Enterococcus species
- Klebsiella pneumoniae
- Influenza virus, respiratory syncytial virus (RSV)
- Premature babies and infants
- Pregnant women
- Surgical and burn patients
- Cancer and diabetic patients
- Immunocompromised individuals (HIV/AIDS, chemotherapy patients)
Preventing the spread of infectious diseases, particularly in hospital settings, requires rigorous infection control measures.
1. Public Health Interventions
- Educating the public on disease transmission and hygiene practices.
- Conducting immunization programs.
- Rapid case identification and notification to public health authorities.
2. Infection Control Measures in Hospitals
- Hand Hygiene: Frequent and proper handwashing with soap and alcohol-based hand sanitizers.
- Sterilization and Disinfection: Proper cleaning of medical instruments and hospital surfaces.
- Use of Personal Protective Equipment (PPE): Masks, gloves, gowns, and eye protection.
- Isolation of Infectious Patients: To prevent the spread of highly contagious diseases.
- Antibiotic Stewardship: Rational use of antibiotics to reduce resistance.
- Proper Waste Disposal: Safe handling of medical waste to prevent contamination.
A. Source Isolation
- Used for patients with contagious diseases to prevent pathogen spread.
- Involves private rooms, restricted movement, and dedicated medical staff.
B. Reverse Isolation (Protective Isolation)
- Used for immunocompromised patients (e.g., leukemia patients, burn victims, premature babies).
- Protects the patient from external infections.
- Requires sterilized rooms, gowns, gloves, and masks for visitors.
