Infection Control In Hospitals

  1. 1. BY:- MR. BINDUSAGAR PATTANAIK DY. HOSPITAL ADMINISTRATOR B.COMM(MGMT. HONS) MHA(MASTER OF HOSPITAL ADMINISTRATION)
  2. 2. Hospital infection control(HIC) Hospital Acquired Infection or Nosocomial Infection is one which manifests itself 72 hours or more after admission to hospital. Aim: To reduce the rate of Hospitals Acquired Infections Objective: To review good practices in infection prevention and control
  3. 3. What is Hospital Acquired infection ? “Hospital-acquired infections”, are infections acquired during hospital care which are not present or incubating at admission. Infections occurring more than 48 hours after admission are usually considered nosocomial.
  4. 4. Contd…  An infection acquired in hospital by a patient who was admitted for a reason other than that infection.  An infection occurring in a patient in a hospital or other healthcare facility in whom the infection was not present or incubating at the time of admission. This includes infections acquired in the hospital but appearing after discharge, and also occupational infections among staff of the facility
  5. 5. Frequency of Infection  HAI occur worldwide and affect both developed and resource-poor countries.  Over 1.4 million people worldwide suffer from such infectious  Most frequent of these are infections of surgical wounds, urinary tract infections and lower respiratory tract infections.
  6. 6. Contd…  The WHO study, have also shown that the highest prevalence of HAI occurs in intensive care units and in acute surgical and orthopedic wards.  Infection rates - higher among patients with increased susceptibility because of old age, underlying disease, or chemotherapy.
  7. 7. Impacts of HAI  Add to functional disability  Increases emotional stress of the patient and may, lead to disabling conditions reducing the quality of life.  The economic costs are considerable.  The increased length of stay for infected patients is the greatest contributor to cost .
  8. 8. Contd…  Hospital-acquired infections add to the imbalance between resource allocation for primary and secondary healthcare.  Prolonged stay not only increases direct costs to patients or payers but also indirect costs due to lost work.
  9. 9. Factors influencing the development of HAI  The Microbial Agent Patient’s exposure to a variety of microorganisms during hospitalization increases the risk of HAI  Environmental factors Health care settings are an environment where both infected persons and persons at increased risk of infection congregate.
  10. 10. Contd….  Patient susceptibility Important patient factors influencing acquisition of infection include age, immune status, underlying disease, and diagnostic and therapeutic interventions. Bacterial resistance Many patients receive antimicrobial drugs. Through selection and exchange of genetic resistance elements, antibiotics promote the emergence of multi drug resistant strains of bacteria.
  11. 11. Hospital Acquired infections are widespread  They are important contributors to morbidity and mortality.  They will become even more important as a public health problem with increasing economic and human impact because of: Increasing numbers and crowding of people. More frequent impaired immunity (age, illness, treatments).  New microorganisms.  Increasing bacterial resistance to antibiotics
  12. 12. Prevention of Hospital Acquired infections is the responsibility of all individuals and services providing health care.
  13. 13. Steps to be taken at a National level to control HAI  Set relevant national objectives consistent with other national health care objectives  Develop and continually update guidelines for recommended health care surveillance, prevention, and practice  Develop a national system to monitor selected infections and assess the effectiveness of interventions .
  14. 14. Contd…  Harmonize initial and continuing training programs for health care professionals facilitate access to materials and products essential for hygiene and safety.  Encourage health care establishments to monitor nosocomial infections, with feedback to the professionals concerned
  15. 15. Hospital Programs to prevent HAI The major preventive effort should be focused in hospitals and other health care facilities Risk prevention for patients and staff is a concern of everyone in the facility, and must be supported at the level of senior administration.
  16. 16. 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 programmes: e.g. management, physicians, other health care workers, clinical microbiology, pharmacy, central supply, maintenance, housekeeping, training services.
  17. 17. Tasks of Infection Control Committee  To review and approve a yearly program 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.
  18. 18. Contd….  to review risks associated with new technologies, and monitor infectious risks of new devices and products, prior to their approval for use  to review and provide input into investigation of epidemics  to communicate and cooperate with other committees of the hospital with common interests such as Pharmacy and Therapeutics Use Committee, Biosafety or Health and Safety
  19. 19. Role of the physician Physicians have unique responsibilities for the prevention and control of hospital infections:  By providing direct patient care using practices which minimize infection  By following appropriate practice of hygiene (e.g. handwashing, isolation)

Contd…  Supporting the infection control team.  Protecting their own patients from other infected patients and from hospital staff who may be infected  Complying with the practices approved by the Infection Control Committee  Obtaining appropriate microbiological specimens when an infection is present or suspected  Notifying cases of hospital-acquired infection to the team, as well as the admission of infected patients
  21. 21. Role of the hospital pharmacist The hospital pharmacist is responsible for:  Obtaining, storing and distributing pharmaceutical preparations using practices which limit transmission of infectious agents to patients  Dispensing anti-infectious drugs and maintaining relevant records (potency, incompatibility, conditions of storage and deterioration)available  Obtaining and storing vaccines or sera, and making them as appropriate  Maintaining records of antibiotics distributed to the medical departments
  22. 22. Contd….  Providing the Antimicrobial Use Committee and Infection Control Committee with summary reports and trends of antimicrobial use.  providing summary reports of prevalence of resistance monitoring sterilization, disinfection and the environment where necessary  Participation in development of guidelines for antiseptics, disinfectants, and products used for  Washing and disinfecting the hands participation in guideline development for reuse of equipment and patient materials
  23. 23. Contd…  providing summary reports of prevalence of resistance  monitoring sterilization, disinfection and the  environment where necessary  participation in development of guidelines for  antiseptics, disinfectants, and products used for  washing and disinfecting the hands  participation in guideline development for reuse  of equipment and patient materials

  55. 55. Prevention of Chemical Spillage Pre-planning is essential. Before working with a chemical, the Hospital worker should know how to proceed with spill cleanup and should ensure that there are adequate spill control materials available. Most spills are preventable. The following can be done to prevent or minimize the magnitude of a spill:
  56. 56. •Place chemical containers in a hood or lab bench in a manner that reduces the possibility of accidentally knocking down a container. •Plan your movements. Look where you are reaching to ensure you will not cause a spill. •Transport the chemicals safely. •Place absorbent liners on bench tops or in places where spills can be anticipated. For volumes of liquid larger than what can be absorbed by liners, use trays.
  57. 57. Radiation Spill— .Generate during body organ imaging ,tumor Localization & therapeutic process in radiology dept. .It generate some solid radio active waste i.e vial, Syringe, absorbent paper , protective clothing .store that in a large drum /container .liquid form are generally diluted & dispensed in the sewers .Gaseous form can be diluted through dispersal In the outside atmosphere.
  58. 58. MANAGEMENT OF MERCURY SPILLAGE : In case of thermometer & B.P. Instrument breaking follow the practice as given below. •Wear Nitrile gloves or double gloves before starting the procedure. •Take 10 ml syringe without needle & draw the mercury. •Push the mercury into the water container. •Document in the” MERCURY SPILL”REGISTER. •Inform Sr. Incharge. Medical director & Supervisor. •Inform house keeping to promptly remove the container. •Handover to the Biomedical department. •Label it as a mercury spill kit with date.
