Infection Control Guidelines

Disclaimers

The guidelines set forth below are intended simply as informal guidelines. Osteopathic physicians and surgeons must comply with all applicable standards for professional practice. These informal guidelines are not to be considered a substitute for the formal recommendations, guidelines and standards contained in the 11 publications referenced below.

Guidelines: Universal Precautions

Universal precautions are an approach to infection control. According to the concept of Universal Precautions, all human blood and certain human body fluids are treated as if known to be infectious for Human Immunodeficiency Virus, Hepatitis B Virus, and other blood-borne pathogens. Universal precautions must be used in the care of all patients.

The Osteopathic Medical Board of California and Cal-OSHA have the authority to adopt and enforce regulations with respect to minimizing the transmission of blood-borne pathogens in health-care settings.

I. Protective Attire

A. Gloves

  • Medical gloves shall be worn when touching blood and body fluids, mucous membranes and non-intact skin of all patients. Gloves shall also be worn when handling items or surfaces soiled with blood and body fluids and when performing venipuncture and other vascular access procedures
  • Gloves shall be changed after contact with each patient or moving from a contaminated to clean body area
  • Sterile Gloves should be used for surgical procedures3
  • Non-sterile gloves may be used for examinations and other non-surgical procedures
  • Rubber utility gloves are used for housekeeping chores that involve potential contact with blood, instrument cleaning and decontamination procedures
  • Do not use any chemical such as petroleum-based hand lotion that may affect the integrity of the gloves7
  • Medical, sterile, and non-sterile gloves may not be washed or disinfected for reuse2

B. Protective Gowns, Laboratory Coats or Uniforms

  • Protective gowns or aprons made of materials that provide an effective barrier should be worn during invasive procedures that are likely to result in the splashing of blood or other body fluids
  • Protective clothing shall be changed at least daily or when visibly soiled
  • Personal protective equipment/clothing shall be removed prior to leaving the work area and placed in an appropriately designated area or container for storage, washing, decontamination or disposal3

C. Surgical Masks, Protective Eyewear or Face Shields

  • Protective eyewear or face shields should be worn for procedures that commonly result in the generation of droplets, splashing of blood or other body fluids or the generation of bone chips3
  • Surgical masks must be worn for invasive procedures and changed between each patient or during treatment if the mask becomes moist or wet
  • Face shields or protective eyewear must be washed and disinfected between each patient or when visibly soiled

II. Barrier Precautions

Protective barriers reduce the risk of exposure of the health-care worker's skin or mucous membranes to potentially infective materials. Universal precautions are those intended to prevent parenteral exposure of health worker's mucous membranes and non-intact skin to blood-borne pathogens.6

Examples of protective barriers include gloves, gowns, masks, and protective eyewear, as indicated above.

Universal precautions apply to blood and other body fluids containing visible blood. These precautions also apply to semen and vaginal secretions. Other substances that are applicable are cerebrospinal fluid, synovial fluid, pleural fluid, peritoneal fluid, pericardial fluid and amniotic fluid. The risk of transmission of HIV and HBV from these fluids is unknown.5

Universal precautions do not apply to feces, nasal secretions, sputum, sweat, tears, urine and vomitus unless they contain visible blood. The risk of transmission of HIV and HBV from these fluids and materials is extremely low or nonexistent.2 ,5, 7

The type of protective barrier should be appropriate for the procedure being performed and the type of exposure anticipated.

III. Hand Washing and Care of Hands

Hands must be washed before and after treating each patient and after bare-handed touching of inanimate objects likely to be contaminated with body fluids.

At a minimum, soap and water should be used between patients. Alcohol-based hand rubs may be used for decontamination if the hands are not visibly soiled. Antimicrobial surgical handscrub must be used for surgical procedures.7

Hands should be washed:

  1. Before and after treating each patient
  2. Before glove placement and after glove removal
  3. After barehanded touching of inanimate object likely to be contaminated with blood or body fluid

Health- care workers who have exudative lesions or weeping dermatitis should refrain from all direct patient care and from handling patient-care equipment until condition resolves.3

IV. Use and Care of Sharp Instruments and Needles

Compliance with the Needlestick Safety and Prevention Act is required by all health care personnel as set forth by OSHA. Employers must maintain a log of occupational injuries and illness under existing recordkeeping rules. At minimum, the log must contain the following:11

  • The brand and type of device involved in the incident
  • The location of the incident
  • The description of the incident

An Exposure Control Plan needs to be implemented to include the following:

  • Annual consideration and implementation of appropriate engineering controls
  • Solicitation of non-managerial healthcare workers in evaluating and choosing devices

Plan must be reviewed and updated annually.

Used needles should never be recapped or manipulated using both hands or by any other technique that involves directing the point of the needle towards any part of the body.

After they are used, disposable syringes and needles, scalpel blades, and other sharp items should be placed in puncture-resistant containers for disposal. These containers should be located as close as is practical to the use area.2

For procedures involving multiple injections with a single needle, the unsheathed needle should be placed in a location where it will not become contaminated or contribute to unintentional needle sticks between injections.

V. Sterilization and Disinfection of Instruments

Before sterilization or high-level disinfection, instruments should be cleaned thoroughly by scrubbing with soap and water or detergent solution or with a mechanical devise ultrasonic cleaner. The use of covered ultrasonic cleaners is recommended to increase efficiency of cleaning and to reduce the handling of sharp instruments. Utility gloves should be worn when handling contaminated instruments.

Single-use disposable instruments must be used for only one patient and discarded appropriately. Single disposable instruments are neither designed nor intended to be cleaned, disinfected or sterilized for reuse.

VI. Housekeeping and Laundry

Environmental surfaces that have become contaminated with patient material shall be cleaned and disinfected after treatment of each patient and the completion of daily work activities.

Countertops and other surfaces should be cleaned with disposable toweling and appropriate cleaning agent. After cleaning, surfaces should be disinfected with a suitable chemical germicide that is approved for use as a hospital disinfectant.

Environmental surfaces such as walls and floors should be cleaned daily or when visibly soiled.

Soiled linen should be handled as little as possible and with minimum agitation to prevent leakage.3

Visible material should be removed and the area decontaminated with a suitable chemical germicide that is approved as a hospital disinfectant and is tuberculoid when used at the recommended dilution. Gloves should be worn during the clean-up procedures.2

VII. Infected Waste Universal Precautions

Policies for collecting, storing, decontaminating and disposing of infected waste are generally determined by institutions in accordance with state and local regulations. Infected waste should be disposed of according to the regulations.2

VIII. Immunization and Infection Control

Mandatory immunizations should be made available to all health-care personnel. OSHA bloodborne pathogen standards mandate that vaccines for Hepatitis B be made available to all health-care personnel at the employer's expense. OSHA standards and guidelines for post-exposure evaluation and follow-up should be followed.6

Current infection control guidelines include:

  1. Personnel health and safety education
  2. Maintain records on job-related illnesses and exposures
  3. Immunization of health-care personnel
  4. Prophylaxis and follow-up after exposure
  5. Personnel restriction due to infectious illness and special conditions

All health-care workers must adhere to the 1998 CDC infection control guidelines and to the 1991 OSHA standards, including HBV vaccination and the use of universal precautions in all health-care settings.6 Adherence to proper infection control procedures, including vaccinations as indicated, is a minimum standard of care.4
