2. Introduction • “The very first requirement in a hospital that it should do the sick no harm" - Florence Nightingale • Health care associated infections(HCAI)- economic loss prolonged hospital stay & adverse patient outcomes. Infection control Biomedical waste management Standard precaution

3. Health care associated infections(HCAI) • Infections that are acquired by the patients while he is in the hospital either from other patients, the environment or members of hospital staff.

4. Health Care Associated Infections Commonly occurring types • Urinary tract infections. • Surgical wound infections. • Respiratory tract infections. • Catheter related blood stream infections. • Meningitis. • Gastroenteritis.

5. Common organisms • Staphylococcus aureus • Enterococcus • Pseudomonas aeruginosa • Klebsiella • E- coli • HIV • HBV • HCV • CMV • candidia

6. • Low resistance of patient to infections. • Invasive procedures/interventions. • Inappropriate anti-microbial usage. • Drug resistance of endemic microbes. • Contaminated environment. Risk due to

7. Sources of HCAI PATIENT E N V I R O N M E N T Exogenous IV medicationOther patients Endogenous Air Hospital staff Fomite Apparatus

8. Risk areas  Nurseries  ICUs  Dialysis units  Transplant unit  ED  Oncology wards  Operation theatre  Delivery rooms  Post op wards

9. Infection control • What is an Infection ? • What is Control ? • Infection control ?

10. Measures practiced by health care personnel to prevent spread, transmission and acquisition of infection between clients, from health care providers to clients and from clients to HCP. Based on Infection control - definition Standard precaution Additional precaution

11. Breaking the Chain of infection

12. Aseptic practices • Hand washing. • Use of barrier nursing –gloves, gown, mask, goggles etc. • Adopting universal and standard precautions. • Care of indwelling devices.

13. Aseptic practices(contd…) • Proper decontamination, disinfection and sterilization of equipment. • Isolation of infected patients. • Environmental cleaning. • Proper disposal of hospital waste.

14. Hand washing • Social/routine Hand washing • Aseptic Hand washing • Surgical Hand washing

15. Hand washing Vs Hand rub Hand washing • Hands visibly soiled. • Before eating or handling food. • After handling contaminated linens , equipment, organic material. • Entering and exiting from clinical setting.

16. Hand rub • Hands not visibly soiled. • After touching clients intact skin. • After touching any inanimate objects.

17. How to Handwash?

18. Decontamination Decontamination Sterilization Steam Dry heat Chemical Cleaning Disinfection Boiling Chemical Steam

19. Disinfection and Sterilization Disinfection : Reduce the number of microorganisms on an object or surface but not the complete destruction of all microorganisms or spores. Sterilization : Procedures, which would remove all microorganisms, including spores, from an object.

20. Disinfectants commonly used • 2% glutaraldehyde (cidex) • 5% phenol • Isopropyl alcohol (bacillol) • Hydrogen peroxide • 1% sodium hypochlorite solution • Calcium hypochlorite (bleaching powder)

21. Sterilization Methods • Dry heat Autoclave • Ethylene oxide • 2% Gluteraldehyde • Gamma radiation

22. Changes observed over a period of time • A switch over to digital thermometers from clinical thermometers. • Using distilled H2O ampoules to dissolve injections rather than using common stock solutions.

23. Current trends(contd…..) • Wet mopping over dry sweeping. • Revised steps of Hand washing. • No more fumigation with formaldehyde. • Dry bottles for Cheatle forceps rather antiseptic solution filled bottles.

24. Infection control Biomedical waste management Standard precaution

25. Standard Precaution As defined by CDC “ Set of practices designed to prevent the transmission of HIV, Hepatitis B and other blood borne pathogens (bacteria & virus). ” Blood & other body fluids of all persons are considered potentially infectious.

26. Body fluids include • Blood • Vomit • Saliva • Feces • Drainage • Secretions from mucous membrane • Semen Sweat and tear mixed with blood

27. Standard precaution steps • Hand washing • Personal protective equipment • Decontamination • Waste disposal

28. Hand hygiene Hand washing is the single most effective measure in infection control. 80% of the diseases are spread through hands.

29. Personal protective equipment • Gloves • Gown • Mask • Protective eye wear • Face shield • Apron

30. Prevention & management of Sharp injury and Spillage • Never recap the needles. • Cannulas with safety needle guards. • Post exposure prophylaxis treatment. • Use of PPE.

31. Proper Disposal of PPE

32. Any waste generated during diagnosis, treatment or immunization of human beings or animals. Waste management is the Collection, transport, processing or disposal, managing and monitoring of waste material. BIOMEDICAL WASTE MANAGEMENT

33. Sources-health care waste  Government and Private hospitals  Nursing homes  Physician’s office/clinics  Dispensaries  Primary Health Centers  Medical research and training establishments  Mortuaries

34. Hazards • Organic portion ferments and attracts fly breeding. • Injuries from sharps - health care personnel and waste handlers. • Risk of infections to medical, nursing and other hospital staff. • Development of resistant strains of microorganisms.

35. • Increase in risk associated with hazardous chemicals and drugs to persons handling wastes. • Poor waste management encourages unscrupulous persons to repacking and reselling. • Poor infection control - nosocomial infections in patients (HIV, Hepatitis B & C). Hazards(contd….)

36.  To reduce hazardous nature of waste.  To reduce volume of waste.  To prevent misuse or abuse of waste.  To ensure occupational safety and health.  To consider aesthetics. Purposes of waste disposal

37. Principles of waste management • Segregate the waste. • Disinfect and mutilate sharps. • Adopt safer technologies as autoclave and microwave. • Don’t burn chlorinated plastics.

38. Principles of waste management(contd..) • Prevent reuse of disposables. • Motivate and train all hospital personnel. • Practice universal precaution. • Follow the biomedical waste rules.
