Role of infection control in patient safety [compatibility mode]

  1. 1. 1
  2. 2. What is Patient Safety? In its simplest form, patient safety is “prevention of harm to patients.” ٢
  3. 3. Infection Control • Infection control (IC) is a quality standard that is essential for the well being and safety of patients. • It affects most departments of the hospital and involves issues of quality, risk management, clinical governance and health and safety. ٣
  4. 4. ٤
  5. 5. International Patient Safety Goals Identification Communication Medication Eliminate Infection Falls ٥
  6. 6. Identification Identify Patients Correctly  Use at least two (2) ways to identify a patient ٦
  7. 7. IPSG.1 Identify Patients Correctly   A collaborative process is used to develop policies and/or procedures that address the accuracy of patient identification Use at least two (2) ways to identify a patient: • • • • •  giving medications giving blood and blood products taking blood samples taking other samples for clinical testing providing treatment or procedure The patient’s Room Number cannot be used as an identifier ٧
  8. 8. Verification Process Correct Patient (Identification) Scope: All radiology procedures  Ask the patient “What is your FULL NAME?” “What is the name of the PROCEDURE you are having today?”. Also ask SITE/SIDE if required  Never state patient’s Name “Do not tell the patient… the patient tells you” E.g. Call “Mr. Abdullah”, then ask the above questions including additional questions related to clinical history as outlined on Request Form ٨
  9. 9. Correct Patient (Identification) Cont.  Inpatients 1. Ask patient to state Full Name/ Procedure 2. Check responses against Referral Form & Patient ID Band (wrist/ankle) including MRN– MANDATORY Do Not Proceed if :  Patient ID Band is absent. Call Ward Nurse to personally ID patient and complete Time Out Verification sticker (all personnel sign).  Patient can not verbalise identity. Nurse Escort must verify patient identity. Complete Time Out Verification sticker (all personnel sign). ٩
  10. 10. Verification Process - Cont.  Outpatients 1.Ask patient to state Full Name/ Procedure 2.Check responses against Referral Form Do Not Proceed if :  Patient can not verbalise identity. Proceed only after :  Identity is verified by accompanying relative, family member, friend or healthcare interpreter. ١٠
  11. 11. Reinforcing the Message Displayed at all imaging consoles Have you checked the Patient ID ? - Prior to the Procedure Asked patient their: • Name • (Procedure) Are you sure ! Checked response & MRN against ID Band & Request Form ١١
  12. 12. Communication Improve Effective Communication  Implement a process/procedure for taking verbal or telephone orders ١٢
  13. 13. IPSG 2: Improve Effective Communication  A collaborative process is used to develop policies and/or procedures that address the accuracy of verbal and telephone communications  Person receiving the following: • Verbal order • Telephone order • Reporting of critical test results Must use a verification “read back” of complete order or test result  The order or test result is confirmed by the individual who gave the order or test result ١٣
  14. 14. Critical Test Results  Ensure that there is collaborative process to determine what they are  Clinical Laboratories      Bedside testing Imaging Studies Electrocardiogram Pulmonary Function Testing other ١٤
  15. 15. “Do Not Use” list:      u IU qd qod Leading decimal point (always use a Leading zero)  Trailing zero ١٥
  16. 16. Medication Safety Improve the Safety of High-alert Medications Remove concentrated electrolytes from patient care units ١٦
  17. 17. IPSG 3: Improve Safety of High Alert Medications   A collaborative process is used to develop policies and/or procedures that address the location, labeling and storage of concentrated electrolytes Concentrated electrolytes are not present in patient care units unless clinically necessary and actions are taken to prevent inadvertent administration in those areas where permitted by policy Remove concentrated electrolytes from patient care units ١٧
  18. 18. Eliminate Eliminate Wrong-site, Wrongpatient, Wrong-procedure Surgery  Use a checklist, including a “timeout,” before surgery  Verify that documents and equipment are correct and functioning properly before surgery  Mark precise site where surgery will be performed ١٨ ١٨
  19. 19. IPSG 4: Ensure Correct-site, Correctprocedure, Correct-patient Surgery  Collaborative process used to develop P&P  Mark the precise site in clearly understood way and involve patient in doing this  Develop process or checklist to verify correct documents and functioning equipment  Use a Checklist including “Time-Out” just before surgical procedure ١٩
  20. 20. Team Time Out – Interventional (invasive) Radiology (All invasive procedures covering CT / Ultrasound / Angiography / Mammography and selective Screening procedures) In procedure room, with patient present. Confirm patient ID, request/consent forms, image data all correct. Site marked by interventional doctor. Team Leader calls Time Out immediately prior to procedure commencement (patient draped) to confirm:  Verification of patient identity (Full Name/MRN/ID Band)  Agreement on the intended procedure  Verification of correct position i.e level & side  Verification of the visible marked site  Availability of correct implants/equipment/medication – DO NOT proceed until resolve discrepancies (document) ٢٠
  22. 22. Infections Reduce the Risk of Health Careacquired Infections A collaborative process is used to develop P&P that address reducing the risk of health care–associated infections   Comply with current published and distributed hand hygiene guidelines IPSG 5: Reduce the Risk of Health Care-Associated Infections. ٢٢
  23. 23.  Contact Precautions  Airborne Precautions  Droplet Precautions ٢٣
  24. 24. Falls Reduce the Risk of Patient Harm Resulting from Falls  Assess and periodically reassess each patient’s risk for falling ٢٤
  25. 25. FALLS  Falls are a common cause of morbidity and the leading cause of nonfatal injuries and traumarelated hospitalizations.  Falls occur in all types of healthcare institutions and to all patient populations.  In hospitals, falls consistently make up the largest single category of reported incidents. ٢٥
  26. 26. IPSG 6: Reduce the Risk of Patient Harm resulting from Falls  Develop P&P using collaborative process  Assess and periodically Reassess each patient’s risk for falling, including the potential risk associated with the patient’s medication regime,  Take action to decrease or eliminate any identified risks. A fall can be prevented by thoughtful strategies designed for the individual patient (e.g., a low bed). ٢٦
  27. 27. Improving Patient Safety means . . . Reducing Medical Errors Reducing HAIs ٢٧
  28. 28. WHO Patient Safety    WHO Patient Safety was launched in October 2004 with the mandate to reduce the adverse health and social consequences of unsafe health care An essential element of WHO Patient Safety is the formulation of a Global Patient Safety Challenge: a topic that covers a significant aspect of risk to patients receiving health care, relevant to every WHO Member State The First Global Patient Safety Challenge was launched in 2005 ٢٨
  29. 29. Through the promotion of best practices in hand hygiene, the First Global Patient Safety Challenge aims to reduce health care-associated infection (HCAI) worldwide ٢٩

  41. 41. What is the KKH Multimodal Hand Hygiene Improvement Strategy? ONE System change  Based on the evidence and recommendati ons from the WHO Guidelines on Hand Hygiene in Health Care (2010), a number of components make up an effective multimodal strategy for hand hygiene Access to a safe, continuous water supply as well as to soap and towels; readily accessible alcohol-based handrub at the point of care TWO Training / Education Providing regular training to all health-care workers THREE Evaluation and feedback Monitoring hand hygiene practices, infrastructure, perceptions and knowledge, while providing results feedback to healthcare workers FOUR Reminders in the workplace Prompting and reminding health-care workers FIVE Institutional safety climate Creating an environment and the perceptions that facilitate awareness-raising about patient safety issues ٤١
  42. 42. So Why All the Fuss About Hand Hygiene? Most common mode of transmission of pathogens is via hands!  Infections acquired in healthcare  Spread of antimicrobial resistance ٤٢
  43. 43. All health care’s works involve the hands ٤٣
