How does your facility handle infectious wastes (not including sharps waste)? What guidelines and procedures are in place for patient and worker safety from infectious wastes? What types of personal protective equipment are used in the management of infectious/sharps waste in your facility? What PPE is available? What are some regulations for management of sharps and infectious waste present in your specific country or region? What are some ways to overcome barriers present in your country/region/facility for effective management of infectious and sharps waste? 3 UNDP GEF Project on Global Healthcare Waste PRESENTATION Slide Number/Title Teacher’s Notes Slide 1: Title Slide Slide 2: Module Overview Introduce the outline and major points of the presentation. The trainer will review the major sources of infectious disease transmission from healthcare waste, with particular emphasis on sharps waste Slide 3: Learning Objectives Slide 4: What is Infectious Waste? Describe what participants will learn at the end of this module. Infectious waste includes: -waste contaminated with blood and other body fluids -laboratory cultures and microbiological stocks -excreta and other materials that have been in contact with patients who are ill with highly infectious diseases in isolation wards Slide 5: Routes of Disease Transmission In addition to information included in slide, introduce the basics of nosocomial infections (as covered in Blue Book). Nosocomial infections are infections that are not present at the time of a patient’s admission to a healthcare facility, but develop during the course of their stay. They are also known as: hospital-acquired infections hospital-associated infections hospital infections They can occur as a result of medical procedures performed on patients that lead to infections with the patient’s own (endogenous) flora or as a result of exposure to items contaminated with infectious agents. Additionally, the risk of acquiring an infection increases for patients with altered or compromised immunity. 4 UNDP GEF Project on Global Healthcare Waste Slide 6: Sources of Disease Transmission Go over the main sources of infectious disease transmission. In the healthcare setting, the sources of infectious agents may be the personnel, the patients, or the inanimate environment. Slide 7: Why are Healthcare Facilities Ideal for Disease Transmission? Slide 8: Chain of Infection Give some primary reasons for why healthcare facilities are ideal for disease transmission It is very important to understand the chain of infection so that the most effective measures can be taken to prevent potential disease transmission. Ask class if they can provide an example of the chain of infection in their facility. There are six elements included in the healthcare facility chain of infection: Infectious agent: a microbial organism that can cause disease Reservoir: a place where micro-organisms can thrive and reproduce e.g. in humans, animals, inanimate objects Portal of exit: a means for a micro-organism to leave the reservoir e.g. respiratory, genitourinary, and gastrointestinal tracts, skin and mucous membranes and the placenta Mode of transmission: how the organism moves from one place to another e.g. contact, droplets, airborne Portal of entry: an opening allowing the micro-organism to invade a new host; usually the same as the portal of exit Susceptible host: a person susceptible to the disease, lacking immunity or physical resistance to prevent infection Slide 9: Who is at Risk? Slide 10: Who is at Risk? Slide 11: Examples of Potentially Infectious Wastes Go over the major groups at risk of infection from healthcare wastes – staff, patients, community – and give some examples for how they might be exposed. Table with categories of infectious waste and examples. 5 UNDP GEF Project on Global Healthcare Waste Slide 12: Where is Potentially Infectious Waste Found? Discuss where sharps waste, bulk blood and body fluids, cultures and biological stocks, and pathological waste might be found in a healthcare facility. Ask participants where they would expect to find infectious wastes within the healthcare facility. Personnel managing potentially infectious waste streams need to be vigilant. The waste stream should be addressed as if they were treating a patient. Containers and sacks used to transport waste can become visibly contaminated with blood and body fluids. Therefore, in addition to wearing personal protective equipment, the staff needs to understand how they may become exposed to infectious agents and how they can eliminate the potential for exposure. Slide 13: Sharps Waste Management Describe all the major aspects of sharps waste management in the next batch of slides. There are many items that can be classified as sharps waste, but hypodermic needles make up the majority of it. Sharps not only cause cuts and punctures, but may also infect these wounds if they are contaminated with pathogens. Because of this double risk – injury and disease transmission – sharps are considered as a very hazardous waste class. Slide 14: Sharps Waste Management Slide 15: Sharps Waste Management Go through some key recommendations for minimizing and preventing needle-stick injuries. Sharps waste should be placed directly in a sharps container, except for syringes, which may need to have their needles removed/destroyed before being placed in an infectious waste bin. Since sharps can cause injuries that leave people vulnerable to infection at a later date, both contaminated and uncontaminated sharps should be collected in a puncture-proof and impermeable container, which is difficult to break or open after closure, and clearly labelled. Sharps containers may be disposable or designed for disinfection and reuse. 6 UNDP GEF Project on Global Healthcare Waste If low-cost options are used, the original labels should be removed or defaced and the containers should be clearly labelled as sharps containers. Slide 16: Sharps Waste Management Go through the recommendations for handling sharps. There may be others that you are aware of. Slide 17: Sharps Waste Management It is important for sharps containers to be readily accessible in areas where sharps are used. The containers should be filled only ¾ full. Go through the points for proper handling of sharps containers. Slide 18: Options for Sharps Waste Treatment Slide 19: Example of Autoclaving and Shredding of Sharps Waste in Tanzania Source: UNDP GEF Project, Health Care Without Harm, AGENDA, John Snow, Inc. Top photos: Autoclave (left) and shredder (right) from India Bottom: Treatment of sharps boxes, right photos show the sharps waste after sterilization and shredding Slide 20: Example of Autoclaves and Re-melting Sharps waste from the hospital and HIHT’s health outreach is collected in autoclavable metal containers and brought back to the hospital where the waste is autoclaved. The sterilized sharps waste is then crushed in a locally built shredder. A bin full of water is used to separate the plastics (which float) and the metals (which sink). The plastics are re-melted to produce other plastic products. (It is possible for sterilized glass to be re-melted into new glass products and metals to be re-melted in a foundry.) Slide 21: Options for Sharps Waste Management Due to the hazards associated with sharps, all infectious or non-infectious sharps should be mutilated and disinfected before their final disposal. There are different devices available for mutilation of sharps at the point of generation. Needle melters and needle cutters are two such devices. 7 UNDP GEF Project on Global Healthcare Waste Slide 22: Needle Cutters/Destroyers Discuss some advantages and disadvantages of needle cutters/destroyers. Advantages and disadvantages of needle cutters/destroyers Advantages -Prevents reuse of syringe either inadvertently or illegally -Reduces volume of sharps wastes -Potential for recycling syringe barrels after disinfection -Removes inclination of staff to recap used needles -Reduces risk of injury from improperly disposed syringes Disadvantages -Cost: one will be needed wherever injections are given and will require maintenance. Sharps containers may still be needed for lancets and other sharps waste -Some models collect the sharps in containers that need to be capped after filling; potential for spilling of needles and/or NSI during container exchange -Potential splash of blood during operation -Busy staff may leave syringes to be cut later, increasing chances of NSI and infection from discarded syringes -Some needle destroyers are electrically operated and so not appropriate where power outages are common . Slide 23: Example of Autoclaves and Re-melting The Swiss Red Cross piloted a project at a hospital in Kyrgyzstan. Hub cutters were used to separate the needles from the plastic barrel immediately after giving an injection. The needles were autoclaved and buried. The plastic portions of the syringes were autoclaved, crushed in a locally-made hammermill shredder, and then sold to a plastic manufacturing plant that remelted the plastics and made them into coathangers, flower pots and covers for electrical wiring. Slide 24: Sharps Waste Management in a LowResource Setting Transport of sharp within the facilities should be carefully planned. Go through some of the listed options for final disposal of sharps waste. The feasibility of each option may depend on the specific region or facility. 8 UNDP GEF Project on Global Healthcare Waste Slide 25: Demonstrations You may choose to move this slide and the associated demonstrations to the end of the presentation. The trainer demonstrates the use jet injectors devices; use of retractable syringes, sheathed syringes, hinged recap syringes, shielded IV catheters and butterfly needles, self-blunting needles, and other safe needle devices available in the country; the use and proper disposal auto-disable syringes; the use of needle destruction technologies and electrical or mechanical needle cutters; the construction of safety boxes and acceptable alternatives to commercial sharps containers. The trainer invites the participants to try the devices, and the trainer and participants discuss the advantages and disadvantages of each. Slide 26: Blood and Body Fluids Present the types of waste contaminated with blood and body fluids that require universal precautions. Go over the special procedures for handling and disposal of bulk blood and body fluids, including management of suction canister waste, use of absorbents, clean-up procedures, use of PPE to prevent exposure to splashes and aerosols, and emergency response to blood splashes. Slide 27: Management of Blood and Body Fluids Go over the special procedures for handling and disposal of bulk blood and body fluids: general disposal, where volume of blood poses a risk, disposal of blood bags, treatment of suction canisters. Ask participants: What they do in their facility? Do you use PPE? How do you disinfect? How do you dispose? What is the spill or emergency response plan? Slide 28: Management of Blood and Body Fluids Slide 29: Management of Blood and Body Fluids 9 UNDP GEF Project on Global Healthcare Waste Slide 30: Cultures and Stocks Describe some sources of cultures and stocks, which are highly infectious wastes Slide 31: Cultures and Stocks Describe procedures for management and disposal of cultures and stocks: use of PPE, on-site steam or chemical disinfection, use of an on-site autoclave Slide 32: Pathological and Placental Waste Describe the treatment and disposal options for pathological waste and placenta waste. Slide 33: Summary of Treatment and Disposal Methods Slide 34: Discussion Present the table summarizing treatment and disposal methods References (in order as they appear in slides) Blue Book, Chapter 3, 12 Ask participants: If some of these technological options are not available or feasible, what should the facility do to handle the waste? Generate a discussion about major topics in this module using the review questions. 10 UNDP GEF Project on Global Healthcare Waste ACTIVITY: MODULE 17: EXERCISE (1 HOUR) The purpose of this activity is to get participants thinking about management, treatment and disposal of sharps and infectious wastes in their facility. Instructor: Break class into groups of three or more, and distribute exercise at beginning of class. You may group participants by facility, department, or job type. Participants will complete the activity in groups and record their answers. Instructor should record participant/group responses on a wipe board, flip chart, or transparency, categorize their responses. Instructor will go over the responses, once again, during the de-brief. MODULE 17 EXERCISE: SPECIFIC INFECTIOUS WASTES Instructor will present the module and objectives and ask participants to: 1. Describe/write the current guidelines/protocols specifically for your healthcare facility for managing: – Sharps – Bulk blood and body fluids – Cultures and stocks – Pathological wastes 2. Think about patient and workers safety. 3. Think about PPE provided. 4. What are some ways to overcome barriers present in your country/region/facility for effective management of infectious and sharps waste? De-brief Instructor will identify the key gaps in management and disposal of infectious and sharps waste and discuss ways to improve management. 11
