-
Gloves: Wearing gloves to protect hands from exposure to blood and body fluids is essential. Gloves should be used during all patient-care activities that may involve contact with blood or other potentially infectious materials.
-
Masks and Eye Protection: Using masks and eye protection to prevent splashes or sprays of infectious materials into the mouth, nose, and eyes. This is particularly important during procedures that generate aerosols.
-
Gowns and Aprons: Wearing protective clothing to shield skin and clothing from contamination. Gowns should be fluid-resistant to prevent blood and body fluids from soaking through.
3. Safe Handling of Sharps
-
Needlestick Prevention: Implementing safe practices for the use, disposal, and handling of needles and other sharp instruments to prevent accidental injuries and manage occupational exposure. This includes using needleless systems and safety-engineered devices.
-
Sharps Disposal: Using puncture-resistant containers for disposing of used needles and other sharps immediately after use. Containers should be located as close as possible to the area where sharps are used to minimize the risk of needlestick injuries.
4. Proper Cleaning and Disinfection
-
Cleaning Protocols: Ensuring proper cleaning and disinfection of patient care areas and equipment, following established protocols and guidelines. This includes the use of EPA-registered disinfectants effective against bloodborne pathogens.
-
Surface Disinfection: Regularly disinfecting surfaces that come into contact with blood or bodily fluids to reduce the risk of cross-contamination.
5. Respiratory Hygiene and Cough Etiquette
-
Covering Mouth and Nose: Encouraging patients and staff to cover their mouth and nose with a tissue or their elbow when coughing or sneezing to minimize the spread of pathogens. Tissues should be disposed of immediately, followed by hand hygiene.
-
Waste Disposal: Proper disposal of tissues and hand hygiene after coughing or sneezing to prevent the spread of respiratory pathogens.
Vaccinations
1. Hepatitis B
-
Vaccination Series: Healthcare workers should receive the hepatitis B vaccine series, which provides immunity against hepatitis B virus (HBV) infection. This vaccination is highly effective in preventing HBV transmission and is recommended for all healthcare workers who may be exposed to blood.
2. Influenza
-
Annual Vaccination: Annual influenza vaccination is recommended to reduce the risk of contracting and spreading the flu, which can weaken the immune system and increase vulnerability to other infections.
3. COVID-19
-
Following Guidelines: Given the ongoing pandemic, healthcare workers should follow national guidelines and recommendations regarding COVID-19 vaccinations to protect themselves and their patients. This includes receiving booster doses as recommended.
Safe Handling and Disposal of Biological Waste
1. Proper Disposal Containers
-
Leak-Proof Containers: Using leak-proof, puncture-resistant containers for the disposal of contaminated sharps and biohazardous waste. These containers should be clearly labeled and placed in strategic locations throughout healthcare facilities.
2. Waste Segregation
-
Waste Segregation: Segregating different types of waste (e.g., sharps, infectious waste, non-infectious waste) to ensure proper disposal and reduce the risk of contamination. Clear labeling and color-coding systems can help staff easily identify and separate waste.
3. Adherence to Regulations
-
Local Guidelines: Adhering to local regulations and guidelines for the collection, transportation, and disposal of biohazardous waste to ensure compliance and safety. Regular audits and inspections can help maintain adherence to these regulations.
Needlestick and Sharps Injury Prevention
1. Use of Safety-Engineered Devices
-
Safety Devices: Utilizing safety-engineered devices, such as retractable needles or needleless systems, to reduce the risk of needlestick injuries. Training on the proper use of these devices is essential to maximize their effectiveness.
2. Immediate Disposal
-
Proper Disposal: Immediately dispose of used needles and other sharps in designated sharps containers, avoiding recapping or bending of needles. Containers should be sealed and replaced when they are three-quarters full to prevent overfilling.
3. Incident Reporting and Follow-Up
-
Reporting Injuries: Report any needlestick or sharps injuries promptly and follow the established procedures for post-exposure management, including assessment, testing, and treatment. This ensures that healthcare workers receive timely care and that the incident is properly documented and investigated.
Blood and Bodily Fluid Exposure Control Plan
1. Immediate Response
-
Cleaning Exposed Area: Cleanse the exposed area with soap and water or flush mucous membranes with water, as appropriate, and report the incident to the designated authority immediately.
2. Documentation and Evaluation
-
Incident Report: Complete an incident report and seek appropriate medical evaluation and follow-up, which may include testing for bloodborne pathogens and consideration of prophylactic measures. Detailed documentation helps track exposure incidents and identify areas for improvement in safety protocols.
