  9. 9. Hospital Infections are Emerging challenges in Health Care Hospital-associated infections represent a serious and growing health problem. The Centers for Disease Control and Prevention (CDC) estimates that 2 million people acquire hospital-associated infections each year and that 90 000 of these patients die as a result of their infections. A variety of hospital-based strategies aimed at preventing such infections have been proposed. Dr.T.V.Rao MD 9
  10. 10. Modern Hospital Infection Control Modern hospital infection control programs first began in the 1950s in England, where the primary focus of these programs was to prevent and control hospital-acquired staphylococcal outbreaks. In 1968, the American Hospital Association published "Infection Control in the Hospital," the first and only standards available for many years. At the same time, the Communicable Disease Center, later to be renamed the Centers for Disease Control and Prevention (CDC), began the first training courses specifically about infection control and surveillance Dr.T.V.Rao MD 10
  11. 11. CHAIN OF INFECTION Dr.T.V.Rao MD 11
  12. 12. Beginning of Accreditation In 1969, the Joint Commission for Accreditation of Hospitals-- later to become the Joint Commission on Accreditation of Healthcare Organizations (JCAHO)-- first required hospitals to have organized infection control committees and isolation facilities. Dr.T.V.Rao MD 12
  13. 13. CDC Initiates Hospital Infection Branch In 1972, the Hospital Infections Branch at the CDC was formed and the Association for Practitioners in Infection Control was organized. By the close of the decade, the first CDC guidelines were written to answer frequently asked questions and establish consistent practice. Dr.T.V.Rao MD 13
  14. 14. First Data on Infection Control Efficacy In 1985, the Study of the Efficacy of Nosocomial Infection Control (SENIC) project was published, validating the cost-benefit of infection control programs. Data collected in 1970 and 1976-1977 suggested that one-third of all nosocomial infections could be prevented Dr.T.V.Rao MD 14
  15. 15. Committee Suggested One infection control professional (ICP) for every 250 beds. An effective infection control physician. A program reporting infection rates back to the surgeon and those clinically involved with the infection. An organized hospital-wide surveillance system. Dr.T.V.Rao MD 15

Infection Control Challenges of Healthcare in 2000 Decreasing reimbursement Increasing emerging infections Increasing resistant organisms Increasing drug costs Institute of Medicine Report--healthcare-associated infections Nursing shortage OSHA safety legislation Multiple benchmark systems FDA legislation on reuse of single-use devices Dr.T.V.Rao MD 16
  17. 17. The nature of infections Micro-organisms - bacteria, fungi, viruses, protozoa and worms Most are harmless [non-pathogenic] Pathogenic organisms can cause infection Infection exists when pathogenic organisms enter the body, reproduce and cause disease Dr.T.V.Rao MD 17
  18. 18. Modes of spread Two sources of infection: Endogenous or self-infection - organisms which are harmless in one site can be pathogenic when transferred to another site e.g., E. coli Exogenous or cross-infection - organisms transmitted from another source e.g., nurse, doctor, other patient, environment Dr.T.V.Rao MD 18 (Peto, 1998)
  19. 19. Spread - entry and exit routes Natural orifices - mouth, nose, ear, eye, urethra, vagina, rectum Artificial orifices - such as tracheostomy, ileostomy, colostomy Mucous membranes - which line most natural and artificial orifices Skin breaks - either as a result of accidental damage or deliberate inoculation/incision (May, 2000) Dr.T.V.Rao MD 19
  20. 20. HAI - common bacteria Staphylococci - wound, respiratory and gastro- intestinal infections Escherichia coli - wound and urinary tract infections Salmonella - food poisoning Streptococci - wound, throat and urinary tract infections Proteus - wound and urinary tract infections (Peto, 1998) Dr.T.V.Rao MD 20
  21. 21. HAI - common viruses Hepatitis A - infectious hepatitis Hepatitis B - serum hepatitis Human immunodeficiency virus [HIV] - acquired immunodeficiency syndrome [AIDS] (Peto, 1998) Dr.T.V.Rao MD 21
  22. 22. Components of Infection Control Programme The important components of the infection control programme are: Basic measures for infection control, i.e. standard and additional precautions; education and training of health care workers; protection of health care workers, e.g. immunization; identification of hazards and minimizing risks; routine practices essential to infection control such as aseptic techniques, use of single use devices, reprocessing of instruments and equipment, antibiotic usage, management of blood/body fluid exposure, handling and use of blood and blood products, sound management of medical waste; Dr.T.V.Rao MD 22
  23. 23. Need For Control programme? Effective work practices and procedures, such as environmental management practices including management of hospital/clinical waste, support services (e.g., food, linen), use of therapeutic devices; surveillance; incident monitoring; outbreak investigation; infection control in specific situations; and research. Dr.T.V.Rao MD 23
  24. 24. Developing Infection Control Programme Every infection control program should develop a well- defined written plan outlining the organizational philosophy regarding infection prevention and control. The plan should take into account the goals, mission statement, and an assessment of the infection control program. It should include a statement of authority, and should review patient demographics including geographic locations of patients served by the healthcare system Dr.T.V.Rao MD 24
  25. 25. Administrative control measures Assignment of responsibilities Administrator Infection control nurse/Engineer Chief doctors/ Head nurses Personnel Responsibility on implementing, monitoring, enforcing, evaluating, and revising infection control programs on a routine basis MD Dr.T.V.Rao including linkage to TB diagnostics 25 and other communicable Infections
  26. 26. Infection control committee An infection control committee provides a forum for multidisciplinary input and cooperation, and information sharing. This committee should include wide representation from relevant departments: e.g. management, physicians, other health care workers, clinical microbiology, pharmacy, sterilizing service, maintenance, housekeeping and training services. The committee must have a reporting relationship directly to either administration or the medical staff to promote programme visibility and effectiveness. Dr.T.V.Rao MD 26
  27. 27. Prevention of Hospital Infection-Planning Implemented, monitored LIFECYCLE OF IC PLAN and enforced IC plan Educated and trained Develop HCW to ensure good work practices Counselling and Evaluate Revise screening HCW Implement periodically Evaluated and revised plan 4 times Dr.T.V.Rao MD 27
  28. 28. The Infection Control Team Consist of at least an infection control practitioner who should be trained for the purpose; carry out the surveillance programme; develop and disseminate infection control policies; monitor and manage critical incidents; coordinate and conduct training activities. Dr.T.V.Rao MD 28
  29. 29. Infection Control Committee Purpose Advisory Review ideas from infection control team Review surveillance data Expert resource Help understand hospital systems and policies Decision making Review and approve policies and surveillance plans Policies binding throughout hospital Education Help disseminate information and influence others 29 Dr.T.V.Rao MD

  32. 32. Aims of Infection Control To review and approve a yearly programme of activity for surveillance and prevention; to review epidemiological surveillance data and identify areas for intervention; to assess and promote improved practice at all levels of the health facility; to ensure appropriate staff training in infection control and safety management, provision of safety materials such as personal protective equipment and products; and training of health workers. Dr.T.V.Rao MD 32
  33. 33. Education is the Real Strength of Infection Control programme Education programs for employees and volunteers are one method to ensure competent infection control practices. It is a unique challenge since employees represent a wide range of expertise and educational background. The ICP must become knowledgeable in adult education principles and use educational tools and techniques that will motivate and sustain behavioral change. Much has been written about the education of healthcare workers (HCWs). Dr.T.V.Rao MD 33
  34. 34. Minimal Needs to Start Infection Control Unit 1 Organized surveillance and control activities 2. One infection control practitioner for every major Health Facility. 3.

  37. 37. Your Unwashed Hand a Great Concern to Your Patient Dr.T.V.Rao MD 37
  38. 38. Hand Washing is the Foundation of Infection Control Hand washing is the single most important procedure for preventing nosocomial infections. Hand washing is defined as a vigorous, brief rubbing together of all surfaces of lathered hands, followed by rinsing under a stream of water. Although various products are available, hand washing can be classified simply by the nature of the products used: plain soap detergents Antimicrobial containing products Dr.T.V.Rao MD 38
  39. 39. Hand Washing is the Foundation of Infection Control Hand washing with plain soaps or detergents (in bar, granule, leaflet or liquid form) suspends microorganisms and allows them to be rinsed off; this process is often referred to as mechanical removal of microorganisms. In addition, hand washing with antimicrobial containing products kills or inhibits the growth of microorganisms; this process is often referred to as chemical removal of microorganisms. Dr.T.V.Rao MD 39
  40. 40. Hand washing Technique For routine hand washing, a vigorous rubbing together of all surfaces of lathered hands for at least 10 seconds, followed by thorough rinsing under a stream of water, is recommended. Dr.T.V.Rao MD 40
  41. 41. Hand washing Single most effective action to prevent HAI - resident/transient bacteria Correct method - ensuring all surfaces are cleaned - more important than agent used or length of time taken No recommended frequency - should be determined by intended/completed actions Research indicates: poor techniques - not all surfaces cleaned frequency diminishes with workload/distance poor compliance with guidelines/training Dr.T.V.Rao MD 41
  42. 42. Hand washing – Areas Missed Taylor (1978) identified that 89% of the hand surface was missed and that the areas of the hands most often missed were the finger-tips, finger-webs, the palms and the thumbs. Dr.T.V.Rao MD 42
