What are these risk categories?Infection Control MethodsKnowledge of Medical asepsis Based on cleanlinessAs few microorganisms as possibleSurgical asepsisSterile environmentNo microorganismsInfection Control Methods (cont.)Keep office cleanPrevent cross-contaminationFollow guidelinesUse protective gearHand HygieneHandwashingAlcohol-based hand disinfectants (AHD)Fingernail lengthNail polish and artificial nailsOther Aseptic PrecautionsAvoid leaning against sinks, etc.Avoid touching your face and mouthUse tissues for coughing or sneezing; wash hands afterwardAvoid working with patients if you have a cold; wear gloves and mask Stay home if you have a feverPersonal Protective EquipmentGlovesMasks and protective eyewear or face shieldsProtective clothingUse of multiple types of PPETransmission from Healthcare WorkersHealthcare-associated infections (HAI)Adhere to OSHA StandardsHigh risk procedures HIV, HBV status of healthcare workersApply Your KnowledgeDescribe the difference between medical and surgical asepsis.ANSWER: Medical asepsis is based on cleanliness and reducing the number of microorganisms as much as possible. Surgical asepsis is maintaining a sterile environment by eliminating all microorganisms.Good Answer!Reporting Guidelines for Infectious DiseasesState or county health departmentInformation is forwarded to the CDC National Notifiable Disease Surveillance SystemReporting Guidelines (cont.)Reporting – correct formDisease identificationPatient identificationInfection historyReporting institution nameApply Your KnowledgeHow is the information on reportable diseases used by the CDC?ANSWER: The CDC uses the information reported to them to help control the spread of infection. Good Answer!In Summary6.1 The medical office safety plan should include OSHA’s Hazard Communication; electrical, fire, and chemical safety; emergency action plans; bloodborne pathogen exposure plans; PPE; and needlestick prevention plans.6.2 The U.S. Department of Labor created OSHA to protect the employees’ safety in the workplace. Through the creation and enforcement of standards such as the Bloodborne Pathogens Standard, Hazard Communication, and the Needlestick Safety and Prevention Act, OSHA serves to protect healthcare workers from hazards.In Summary (cont.)6.3 To reduce electrical hazards in the medical office, you should avoid using extension cords, repair or replace damaged cords, avoid overloading circuits, ensure that all plugs are grounded, dry your hands before using electrical devices, and keep electrical devices away from sinks or other sources of water.6.4 A comprehensive fire safety plan must include fire prevention strategies, actions to take in the event of a fire, building evacuation routes and plans, fire drills, and local emergency contacts.In Summary (cont.)6.5 When using chemicals in the medical office, you should always wear protective gear, carry the container with both hands, work in a well-ventilated area, never combine chemicals unless it is specifically required in the test procedures, and properly clean up spills immediately.6.6 In order to protect yourself from work-related musculoskeletal disorders at work, you must follow the principles of good body mechanics. Your physical safety at work depends on understanding and applying appropriate workplace safeguards.In Summary (cont.)6.7 In order for an infection to occur, these five elements must be in place: a reservoir host, a means of exit, a means of transmission, a means of entrance, and a susceptible host. The most effective means of breaking the cycle of Infection is by using aseptic techniques. 6.8 Laws set forth in the OSHA Bloodborne Pathogens Standard of 1991 dictate how you must handle infectious or potentially infectious waste generated during medical or surgical procedures. In Summary (cont.)6.9 The two basic methods of infection control are medical asepsis and surgical asepsis. OSHA recommends that healthcare workers who work with high-risk patients know their HIV and HBV status, participate in a HBV vaccination program, and avoid direct patient contact if they have a skin condition characterized by sores that secrete fluid. 6.10 The CDC requires reporting of certain diseases to the state or county department of health, who then reports the information to the National Notifiable Disease Surveillance System of the CDC.End of Chapter 6Soap and education are not as sudden as a massacre, but they are more deadly in the long run.~ Mark Twain
