Prevention and Control of Hospital-Acquired Infections in Healthcare Facilities
Hospital-acquired infections (HAIs), also known as nosocomial infections, are infections that patients acquire while receiving treatment in healthcare facilities. These infections represent a serious public health problem worldwide, particularly in low-resource settings where infection prevention and control measures may be insufficient.
The main causes of hospital-acquired infections include poor hand hygiene practices among healthcare workers, improper sterilization of medical equipment, overcrowded hospital environments, and inadequate infection control protocols. In many healthcare facilities, limited access to clean water and disinfectants further increases the risk of transmission.
Patients in intensive care units, surgical wards, and neonatal units are especially vulnerable due to weakened immune systems and exposure to invasive procedures such as catheter insertion, surgery, and mechanical ventilation.
Prevention of hospital-acquired infections requires strict adherence to infection prevention and control (IPC) guidelines. Hand hygiene remains the most effective and cost-efficient measure in reducing infection transmission. The use of personal protective equipment (PPE), proper sterilization of instruments, and regular disinfection of hospital surfaces are also essential measures.
In addition, continuous training of healthcare workers plays a crucial role in improving compliance with safety protocols. Surveillance systems should be implemented in hospitals to monitor infection rates and identify outbreaks early.
Antimicrobial resistance (AMR) is another growing concern linked to hospital-acquired infections. The misuse and overuse of antibiotics contribute to the emergence of resistant pathogens, making infections more difficult to treat. Rational use of antibiotics under medical supervision is therefore necessary to combat this issue.
Strengthening infection prevention programs, improving hospital infrastructure, and ensuring adequate supply of medical resources are key strategies to reduce the burden of hospital-acquired infections and improve patient safety outcomes.
