Abstract

  

Introduction

Nosocomial infections, also known as hospital-acquired infections (HAIs), are infections that are acquired by patients during their stay in a healthcare facility, such as hospitals, nursing homes, and outpatient clinics. These infections are not present or incubating at the time of admission but develop after the patient enters the healthcare setting. [

Nosocomial infections have become a significant concern for public health due to their prevalence, potential for serious complications, and role in prolonging hospital stays, increasing healthcare costs, and contributing to patient morbidity and mortality. Despite advances in infection control practices, nosocomial infections remain a major challenge for healthcare systems worldwide. This article examines the types of nosocomial infections, their risk factors, impact on patients and healthcare systems, and current prevention and control strategies.[

The use of medical devices such as catheters, ventilators, and surgical drains provides a direct pathway for pathogens to enter the body. Devices that are inserted into the body for extended periods, such as central venous catheters, have a higher risk of causing infections. Patients with weakened immune systems, such as those undergoing chemotherapy, organ transplants, or with HIV/AIDS, are at a higher risk for nosocomial infections. [3, 4].

Their reduced ability to fight infections makes them more susceptible to opportunistic pathogens. The overuse or misuse of antibiotics can lead to the development of antibioticresistant bacteria, which are difficult to treat and more likely to cause infections. Methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), and multi-drug resistant Pseudomonas aeruginosa are examples of pathogens commonly associated with nosocomial infections.[5].

The longer a patient is in the hospital, the higher the likelihood of acquiring a nosocomial infection. Long hospital stays increase exposure to pathogens and may involve repeated medical procedures that can introduce bacteria into the body. Any surgical procedure, particularly those involving the use of foreign materials or implants, increases the risk of infection. Surgeons and healthcare workers who do not follow proper sterile techniques can inadvertently introduce pathogens into the surgical site. [6, 7].

Healthcare facilities must implement and strictly adhere to infection control protocols. This includes hand hygiene, the proper use of personal protective equipment (PPE), and the sterilization of medical equipment. Regular audits and training programs for healthcare workers are essential in maintaining high standards of infection control. [8].

Proper management of antibiotic use is critical to prevent the development of antibiotic resistance. Hospitals should adopt antibiotic stewardship programs that promote the judicious use of antibiotics, ensuring that they are prescribed only when necessary and that the correct antibiotic is chosen. Hospitals should have surveillance systems in place to monitor the incidence of nosocomial infections. Early detection of infections allows for quicker interventions and reduces the spread of pathogens within healthcare settings. Regular cleaning and disinfection of hospital surfaces, patient rooms, and high-touch areas (e.g., bed rails, door handles) can help reduce the spread of infections. Proper cleaning protocols should be followed for all hospital environments, particularly in ICUs and surgical areas [9, 10].

conclusion

Nosocomial infections represent a serious challenge to patient safety and healthcare systems worldwide. They lead to prolonged hospital stays, increased healthcare costs, and, most importantly, significant morbidity and mortality. While advances in infection control practices, antimicrobial stewardship, and surveillance have made a difference in reducing the incidence of hospital-acquired infections, further efforts are needed to improve prevention strategies, particularly in light of rising antibiotic resistance. A continued commitment to infection prevention, early detection, and the responsible use of antibiotics is essential in minimizing the impact of nosocomial infections. By fostering a culture of safety and hygiene, healthcare facilities can protect patients, healthcare workers, and the broader community from the dangers of hospital-acquired infections.
