# COVID-19 Outbreak Investigation and Management

**COVID-19 Outbreak Investigation and Management**

** **

**Policy**

** **

It is the policy of this facility to recognize and contain COVID-19 outbreaks and outbreak measures will be instituted whenever there is evidence of an outbreak as outlined below.

 

The Infection Preventionist, or designee, will conduct the COVID-19 outbreak investigation and has the authority to implement and/or direct outbreak measures to control possible transmission. These actions will be carried out in coordination with the Medical Director, administration, and medical staff as well as state and local health agencies. In the absence of the Infection Preventionist, the Director of Nursing or the Assistant Director of Nursing or designee will conduct the investigation.

 

Appropriate notifications to the Medical Director, Administrator, all departments, attending physicians, state and local agencies, and resident representatives will take place as soon as possible after the outbreak has been identified.

 

Outbreak monitoring and reporting will continue until the outbreak has resolved. The facility will send all appropriate reports to state, local health department agencies and National Healthcare Safety Network (NHSN) in accordance with State and Federal requirements.

** **

Control measures include:

- Identifying space in the facility that will be dedicated to care for residents with confirmed COVID-19
- Identify dedicated, essential staff to work the COVID-19 floor, unit, or wing
- Single/private room for resident new admissions and readmissions for 14-day quarantine
- Single/private room for residents exposed to COVID-19 for 14-day quarantine
- Testing
- Reporting
- Active screening of staff, visitors, vendors
- Resident screening and monitoring
- Management/restricted of communal areas for dining and activities
- Physical/Social Distancing
- Personal Protective Equipment
- Universal Source Control
- Hand Hygiene
- Physical/Social Distancing
- Visitation restriction during outbreaks
- Cleaning and Disinfection

 

An interdisciplinary evaluation of the COVID-19 outbreak will be completed, and findings and recommendations will be presented at the quarterly Quality Assurance Committee meeting.

 

Definitions

 

The Centers for Medicare & Medicaid Services indicates, “An outbreak is defined as a new COVID-19 infection in any healthcare personnel (HCP) or any nursing home-onset COVID-19 infection in a resident.”1

 

**Please check with your State specific guidance for COVID-19 Outbreak in Nursing Facilities

** **

**Goal of COVID-19 Outbreak Investigation and Management**

The goal of outbreak investigation and management is to rapidly identify any new cases of COVID-19, prompt resident placement in isolation on the COVID-19 designated unit/area, begin outbreak testing and follow facility systems to stop any further spread of COVID-19 in the facility.

** **

**COVID-19 Outbreak Prevention:**

 

All residents and healthcare personnel will be educated on COVID-19 to include:

- COVID-19 and Signs/Symptoms
- Personal Protective Equipment (PPE)
- Resident Placement
- Universal Source Control 
    - Healthcare personnel
    - Residents
- Physical/Social Distancing
- Respiratory Hygiene and Cough Etiquette
- Visitation Policies and Procedures
- Communal Dining and Activity Areas
- Hand Hygiene
- Testing
- Reporting
- Screening of Staff, Visitors, Vendors
- Resident Screening and Monitoring
- Cleaning and Disinfection

** **

** **

** **

**COVID-19 Outbreak Prevention Measures for Healthcare Personnel**

** **

1. Healthcare Personnel must be screened upon entrance to the facility.       Healthcare Personnel with fever and/or signs or symptoms of COVID—19 are restricted from work and will be tested for COVID-19

1. Healthcare Personnel routine testing to be completed based upon the Community COVID-19 Activity Level in accordance with CMS Guidance1: 
     - See COVID-19 Antigen Testing Policy and Procedure

** **

**COVID-19 Outbreak Measures for Residents**

** **

In the event of an outbreak or suspected case, the DON, Infection Preventionist, Administrator and Medical Director will be contacted to direct the process:

1. All facility residents 
     - Screening (identify facility policy, i.e.3 times/day) for fever and signs/symptoms of COVID-19 and potential exposure
2. New Admissions/Readmissions 
     - Private/Single room in a separate observation area for 14 days under monitoring and evaluation to identify evidence of COVID-19
     - “Testing at the end of the 14-day observation period can increase certainty that resident is not infected.”3
     - “A resident who is admitted to the facility with COVID-19 does not constitute a facility outbreak.” Resident should be placed onto the COVID-19 designated unit/area and placed on isolation.1

1. Rapid identification that an outbreak exists.
2. To implement immediate response:

- Prompt testing 
    - POC Antigen
    - RT-PCR (with lab able to provide results in less than 48 hours)
- Place resident in a private room in separate observation area awaiting results

- Isolation on dedicated COVID-19 wing/unit
- Full Personal Protective Equipment (PPE) to prevent the spread of the COVID-19 outbreak: 
    - Gloves
    - Gown
    - Eye Protection
    - N95 or higher respirator
- Implement dedicated, essential staffing on COVID-19 wing/unit

- Resident should be tested for COVID-19, placed in a private room and observed under quarantine for 14 days. 
    - Full PPE for all employees entering room 
          - Gloves
          - Gown
          - Eye Protection
          - N95 or higher respirator

- During a facility outbreak, full PPE for the care of all residents: 
    - Gloves
    - Gown
    - Eye Protection
    - N95 or higher respirator

 

- Outbreak testing of all residents previously tested negative until no new cases identified 
    - “For outbreak testing, all staff and residents should be tested, and all staff and residents that tested negative should be retested every 3 days to 7 days until testing identifies no new cases of 3 COVID-19 infection among staff or residents for a period of at least 14 days since the most recent positive result.”1 
          1. The CDC indicates, “if testing capacity allows and does not divert staff and resources away from performing other critical IPC measures (e.g., ensuring effective implementation of [Transmission-Based Precautions](https://www.cdc.gov/coronavirus/2019-ncov/infection-control/control-recommendations.html)for infected and potentially exposed residents), the facility should consider testing more frequently (e.g., every 3 days) for the first two weeks of the outbreak, then test less frequently (e.g., every 7 days) thereafter until no new cases are identified for 14 days.”2
          2. When testing of asymptomatic residents is completed as part of an outbreak response, “if an antigen test is positive, no confirmatory test is necessary. Residents should be placed in transmission-based precautions.”4
    - Communal dining and activities will be halted during an outbreak
    - Physical/Social distancing will be practiced by all staff and residents whenever possible
    - Universal source control 
          - Residents
          - Employees
    - Visitation restriction during outbreak with exception of compassionate care situations

 

**COVID-19 Outbreak Measures for Healthcare Personnel (Employees)**

 

1. **Healthcare Personnel** must be screened upon entrance to the facility. Employees with fever and/or signs or symptoms of COVID—19 are restricted from work and will be tested for COVID-19.

- If testing results indicate COVID-19 is confirmed, employee will be sent home and facility will follow the CDC guidance on “Criteria for Return to Work for Healthcare Personnel with SARS-CoV-2 Infection”
- All healthcare personnel that previously tested negative will be tested followed by retesting every 3-7 days until testing identifies no new cases for at least 14 days since the most recent positive results.1 
    - “If testing capacity allows and does not divert staff and resources away from performing other critical IPC measures (e.g., ensuring effective implementation of [Transmission-Based Precautions](https://www.cdc.gov/coronavirus/2019-ncov/infection-control/control-recommendations.html)for infected and potentially exposed residents), the facility should consider testing more frequently (e.g., every 3 days) for the first two weeks of the outbreak, then test less frequently (e.g., every 7 days) thereafter until no new cases are identified for 14 days.”2
