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...

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...

Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

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...

Standard Precaution

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Hospitals-I

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Summary

Healthcare-associated infections (HAIs) prevalence decreased in U.S. hospitals from 2015 to 2023, with 1 in 38 patients affected. Despite this decline, the overall burden of HAIs remains substantial.

Area of Science:

Infectious Disease Epidemiology
Hospital-Acquired Infections Surveillance
Public Health Research

Background:

Healthcare-associated infections (HAIs) pose a significant public health challenge in U.S. hospitals.
Previous surveys indicated a prevalence of 1 in 31 patients with HAIs in 2015.

Purpose of the Study:

To assess the changes in HAI prevalence in U.S. hospitals since 2015.
To estimate the national burden of HAIs in 2023.

Main Methods:

Utilized established methods from the Emerging Infections Program (EIP) network.
Conducted a survey in up to 25 hospitals per EIP site between May and September 2023.
Reviewed medical records of randomly selected patients to identify HAIs using National Healthcare Safety Network definitions.

Main Results:

In 2023, 2.6% of patients (1 in 38) had HAIs, a decrease from 3.2% (1 in 31) in 2015.
Approximately 60% of HAIs were not associated with devices or procedures.
An estimated 518,000 HAIs occurred in U.S. hospitals in 2023.

Conclusions:

The prevalence of HAIs in U.S. hospitals has decreased between 2015 and 2023.
Despite the decrease in prevalence, the overall burden of HAIs remains high.
A majority of identified HAIs were not linked to medical devices or procedures.
