An IP is preparing the quarterly report for the Infection Control Committee. What information will be needed to calculate a CLABSI rate for the ICU? 1) The total number of patient in the unit for the time period 2) The total number of central line catheters for the time period 3) The number of patients who had blood stream infections 4) The number of device days for the time period 2,3 1,3 1,2 3,4

Answer D . 3,4 Rationale: The numerator would be the number of patients who had a blood stream infection identified and who had a central line during the time period. The denominator would be the number of device days (at the same time everyday, count the number of patients with one or more central lines) for the time period.

Identify the median in the following list of numbers: 6,2,9,7,1,4 5 4

Answer C. 5 The median of a data set s the number that 50 percent of the values fall below and 50 percent of the values fall above. The data here are not presented in numerical order so first they must be ordered from lowest to highest. 1,2,4,6,7,9 There is an even number of values in this set so to find them the median one must identify two central numbers then average them together.

An appropriate indicator to monitor compliance would be : Class 1 SSI Rate Appropriate antibiotic dosage Central line associated blood stream infection in NICU Infections caused by multi drug resistant organisms

B. Appropriate antibiotic dosage A surveillance program should monitor a variety of outcomes processes and event and some indicators should focus on personnel.

Which of the following patients is not at high risk for healthcare associated fungal infection? Burn patient Premature baby in the NICU Bone Marrow transplant patients Patient who underwent joint replacement surgery

ANSWER D. Patient who underwent joint replacement Fungi are increasingly being identified as HA Pathogens. Patients at high risk are patients with leukemia, patient with solid tumors or leukopenia, bone marrow transplant patients, injection drug users, cardiothoracic surgery, burn patients and premature or low birth weight infants.

An autopsy is ordered on a patient who was diagnosed with TB An autopsy is ordered on a patient who was diagnosed with TB. Which of the following statements is correct regarding postmortem care of a deceased TB patient? Autopsy rooms should be positive pressure with respect to adjacent areas and room air must be exhausted directly outside. An oscillating autopsy saw should be used to reduce the infectious aerosols An approved mask is necessary for respiratory protection Standard precautions are sufficient because Mycobacterium tuberculosis needs a living host to survive.

ANSWER C. An approved mask is necessary for respiratory protection. OSHA classifies performance of an autopsy on a known or suspected TB case to be a high hazard procedure requiring personnel to use approved respiratory protection.

Most healthcare associated pathogens are transmitted from patient to patient via: Improper isolation practices Inadequate sterilization of medical instruments Hands of a healthcare personnel Ineffective disinfection of medical devices.

ANSWER C. Hand of healthcare personnel According to literature most health care associated pathogens are transmitted patient to patient via the hands of the healthcare personnel. HAND HYGIENE is therefore the simplest most effective proven method to reduce HAI.

For which of the following procedure is the surveillance period for deep incisional or organ/space SSI 90 days? Cesarean Section Craniotomy Coronary artery bypass graft Laminectomy 1,2 2,3 3,4 1,4

ANSWER 2,3 According to CDC SSI surveillance definitions post operative surveillance for deep incisional or organ/space SSIs should be conducted for 90 days on craniotomy and coronary artery bypass procedures. Superficial incisional SSIs are only follower for a 30 day period for all procedure types.

What key infection control activity is defined as the systematic ongoing collection, management, analysis, and interpretation of data followed by the dissemination of these date to public health programs to stimulate public health action? Research Surveillance Benchmarking Accreditation

ANSWER B. Surveillance Surveillance is the “ongoing collection, collation and analysis of data and the on going dissemination of information to those who need to know so that action can be taken” It is essential component of an effective infection prevention and control program.
