Share an example of a time when you had to investigate and control an outbreak of a healthcare-associated infection.

Sample interview questions: Share an example of a time when you had to investigate and control an outbreak of a healthcare-associated infection.

Sample answer:

Investigating and controlling an outbreak of a healthcare-associated infection (HAI) requires a systematic and multidisciplinary approach. Here’s an example of a situation I encountered as an Infectious Disease Nurse:

Scenario:

A surgical unit in a hospital experienced an outbreak of surgical site infections (SSIs) caused by Methicillin-resistant Staphylococcus aureus (MRSA). The infection rate exceeded the expected baseline, and several patients developed complications due to the infection.

My Role:

As an Infectious Disease Nurse, I was tasked with investigating and controlling the outbreak. I collaborated closely with the infection prevention and control team, microbiology laboratory, and surgical team to implement a comprehensive response.

Investigation:

1. Data Collection: I gathered relevant data, including patient demographics, medical history, surgical procedures, antibiotic use, and laboratory results. This helped identify potential risk factors and trends.

2. Environmental Sampling: I conducted environmental sampling in the surgical unit to identify potential sources of MRSA contamination. This included sampling of high-touch surfaces, medical devices, and air quality.

3. Patient Interviews: I interviewed affected patients and healthcare personnel to gather information about potential exposures, symptoms, and compliance with infection prevention practices.

Control Measures:

1. Isolation and Cohorting: Patients with confirmed or suspected MRSA infection were placed in isolation to prevent further transmission. Cohorting of patients with similar infections was implemented to minimize the risk of cross-contamination.

2. Enhanced Barrier Precautions: Strict adherence to hand hygiene, use of personal protective equipment (PPE), and proper disinfection of equipment and surfaces were emphasized to minimize the spread of MRSA.

3. Antibiotic Stewardship: I worked with the antimicrobial stewardship team to ensure appropriate antibiotic use and prevent the emergence of antibiotic resistance. This included reviewing antibiotic prescriptions, monitoring ant… Read full answer
