Role of Infection Control Team in Oncology Dr Afia Zafar Associate Professor Chairperson, Infection Control Committee Department of Pathology Microbiology Aga Khan University
Oncology Patient • Medical oncology • Surgical oncology • Radiation oncology • Pediatric oncology • HSCT (Hemopoietic Stem Cell Transfusion) Allogeneic , Autologous
Risk of Infection • Factors determining immunosuppression: -Primary factor for infection: Defect in host defense -Type, dose, duration of anticancer medication or treatment -Invasive procedures, e.g central lines -HSCT -Exposure to high risk units, e.g ICU

Infections • Blood Stream Infections • Surgical Site Infections • Respiratory tract infections • Skin & Subcutaneous Infections culture of catheter tip &/or insertion site section of catheter
Organization of Infection Control • Infection Control Committee: Clinicians, Administrator, staff from support services, Infection control doctor, Infection control nurse, epidemiologist • Infection Control Team: infection control doctor, infection control nurse, epidemiologist
Infection Control Activities • Policies and Procedures • Surveillance& Trends • Outbreak investigation • Audit /Education
Hand Hygiene Isolation Intravascular catheters Food preparation & handling Visitors Healthcare workers Environment Surfaces Equipment Plants & Flowers Blood Product Screening Construction & renovation Prevention of Transmission Policies and Procedures
Hand HygieneFirst line of defense • Alcohol base handrub • Visibly contaminated-antimicrobial soap • Accessibility • Sinks • Alcohol based hand rub • ICN Daily round in high risk areas / Reinforce hand hygiene
Technique illustrated for use of liquid soap or antimicrobial soap. It is important to complete the entire sequences; however, the order in which you complete the sequence is not critical. Rub back side of hands and between fingers of both hands. Pinching motion in the palm of both hands to clean under fingernails. Apply 2-3 ml of soap palm to palm. hand washing procedure Rub palm to palm with fingers interlaced. Rub top of fingernails with fingers interlocked. Rotational rubbing of thumbs of both hands.
Personal Protective Equipment Policy • Gloves • Gowns • Masks • Patient Care Equipment
Isolation • Air Handling Systems • Not necessary in routine care of oncology patients • Selective use for HSCT • Total Protective Environment and HEPA filters • Not necessary in routine care of oncology patients • Selective use for HSCT

Patient Hygiene Policy Oral Care: Education regarding oral & dental hygiene, Teeth brushing, Dental supervision Skin CareDaily showers or bath, Daily inspection of skin sites Perineal CareGood perineal care, Avoid the use of items that would cause mucosal breakdown
Environmental cleaning Policy • Surfaces: furniture & floors easy to clean, clean once/day, Wet cloths & mops • ICC approved disinfectant • Toys: easy to clean & disinfect, hard plastic toys • Do not stock pile in room • Plants and flowers
Intravascular Devices • Policies and Procedures Guidelines available • Special Insertion Teams&Trained persons for dressing • Maximal Sterile Barriers Sterile gloves & gowns, cap, large drape • Selection of type of catheter and site: No tunneled vs. tunneled catheters, Implantable ports, Subclavian, basilic, cephalic, IJ, femoral
Surveillance • High Risk Infections • Increased morbidity & mortality • Targeted Infections • Central line infections • Disseminated fungal infections • Denominators: • Central lines/1000 central line days • Infections/1000 patient days

Food Preparation & Handling • Low microbial diet • Adequately cooked food • Education • Policy • Practice • Audit by ICN
Visitors policy • Screened for potential infectious conditions • Visitors with active infection • Age requirement • Restriction of visitors • Education: • Communicable diseases • Hand hygiene • PPE if required for Additional Precautions
Health Care Workers • Immune Status & Immunization: • Measles, mumps, rubella, varicella • Inactivated polio vaccine • Restriction or Reassigned: • Diseases transmissible by air, droplet & direct contact: • Varicella • Gastroenteritis • HSV lesions of lips or fingers • Upper Respiratory Infections
Construction & Renovation • Increased risk of fungal infections • Aspergillus • Construction Guidelines new facilities or renovation: Involvement of infection control from planning phase
Conclusions • Problems of nosocomial infections in the oncology unit are more complex as in any other unit • Nonexistence of Infection control activities in these areas further exacerbate the problems resulting worse outcome • It is mandatory that each hospital treating cancer patients should have an active Infection Control group to handle these important issues
