A Tribute to Ignaz Semmelweiss (1818-1865)

Ignaz Semmelweiss (1818-1865)

  • Obstetrician, practised in Vienna
  • Studied puerperal (childbed) fever
  • Established that high maternal mortality was due to failure of doctors to wash hands after post-mortems
  • Reduced maternal mortality by 90%
  • Ignored and ridiculed by colleagues

why do we need infection c ontrol
Why do we need Infection Control??

Hospitals and clinics are complex institutions where patients go to have their health problems diagnosed and treated

But, hospitals, clinics, and medical/surgical interventions introduce risks that may harm a patient’s health

Dr.T.V.Rao MD

what is nosocomial infection
What is Nosocomial Infection
  • Any infection that is not present or incubating at the time the patient is admitted to the hospital

Dr.T.V.Rao MD

Consequences of Nosocomial Infections

  • Additional morbidity
  • Prolonged hospitalization
  • Long-term physical, developmental and neurological sequelae
  • Increased cost of hospitalization
  • Death

hospital infections are emerging challenges in health care
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

modern hospital infection control
Modern Hospital Infection Control
  • Modernhospital 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

beginning of accreditation
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

cdc initiates hospital infection branch
CDCInitiates 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

first data on infection control efficacy
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

committee suggested
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

infection control challenges of healthcare in 2000
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

  • Multiple benchmark systems
  • FDA legislation on reuse of single-use devices

Dr.T.V.Rao MD

the nature of infections
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

modes of spread
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 (Peto, 1998)

Dr.T.V.Rao MD

spread entry and exit routes
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

hai common bacteria
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

hai common viruses
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

components of infection control programme
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

need for control programme
Need For Control programme?
  • Effective work practices and procedures, such as environmentalmanagement 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

developing infection control programme
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

Administrative control measures Assignment of responsibilities

Responsibility on implementing, monitoring, enforcing, evaluating, and revising infection control programs on a routine basisincluding linkage to TB diagnostics and other communicable Infections

Dr.T.V.Rao MD

infection control committee
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.

aims of infection control
Aims of Infection Control
  • To review and approve a yearly programme of activity for surveillanceand 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

education is the real strength of infection control programme
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

minimal needs to start infection control unit

hand washing is the foundation of infection control
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

hand washing is the foundation of infection control39
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

hand washing technique
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

hand washing
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

hand washing a reas m issed
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.Hand washing – Areas Missed
