CDC Nursing Home Infection Prevention Exam
How many Americans does the 15,600 CMS provide to each year?
3 million Americans
Skin and Soft Tissue Infections
95% of skin infections are treated with antibiotics (more than 50% of antibiotics prescribed ordered by off-site provider, less than 50% had documented follow-up evaluation ithin 48 hours which all requires regular evaluations - scabies and bed bugs are common causes of infections and outbreaks in nursing homes)
Clostrodium difficile - C.Diff
A germ (bacterium) that causes diarrhea and colitis (an inflammation of the colon), commonly transmitted through bacterial spores - symptoms include diarrhea, belly pain, and fever; treatment includes antibiotics (often included in AR) CONTACT PRECAUTIONS NEEDED
Susceptible Host
A person likely to get an infection or disease - depends on persons characteristics like age
Tuberculosis
A serious infectious disease caused by Myobacterium tuberculosis, national incidence is low but there are populations with high rates like those over 65, approx. 90% of cases among older adults are from reactiviation of latent infection
Antibiotic Stewardship
A set of commitments and actions designed to optimize treatment of infections while decreasing adverse events and harms associated with antibiotic use - measure antibiotic prescribing, ensure prompt initiation of the right antibiotics when needed, ensure right drug, dose, duration, are selected when antibiotic is started
OSHA Staff Education
Circumstances to wear PPE, donning, doffing, failure/ breech, safely discarding PPE - employees must be offered training upon hire, annually, when new products are introduced, when new policies are written, and in response to deviations
How to Collect a Sample for Urinalysis
Cleanse sampling port with disinfectant, access sampling port with sterile syringe or needle (drainage bag should only be accessed for non-culture related analysis)
Staphylococcus aureus
Colonizes anteriors nose and skin of about 30% of adults (common cause of skin, soft tissue, and wound infections) - skin abscess, cellulitis, wound infections with purulent drainage, can cause invasive bloodstream infections in indwelling residents
Semi-Critical Equipment
Comes into Contact with mucous membrane and noninstact skin. Ex: cuticle and nail clippers. Requires high-level disinfection complete elimination of all microorganisms, except small number of bacterial spores
Non-Critical Equipment
Comes into contact with intact skin like BP cuffs, stethoscopes, rehab. equipment and walking aids -> low to intermediate disinfection
Peripheral Inserted Central Catheter (PICC)
Common in nursing homes, inserted in peripheral vein (upper arm, threated into a central vein) can be left in for weeks -> months (inserted by radiologists or nursing specialists)
CDRSS
Communicable Disease and Reporting Surveillance System
CDS
Communicable disease service
When Putting Resident on TBP, HCP Should...
Communicate with resident the reasons for initiating precautions, PPE staff will be using, whether resident has limitations, inform resident when TBP has been modified, signage in front of resident room should explain TBP but NO PERSONAL INFORMATION/ DIAGNOSIS
Norovirus
Highly contagious, spreads by direct contact, alcohol-based hand rubs may not be effective - can get it from having direct contact with an infected person, consuming contaminated food or water, touching contaminated surfaces and then putting your unwashed hands in your mouth - single type of virus that causes gastroenteritis CONTACT PRECAUTIONS NEEDED
How Antibiotic Resistance Happens
Lots of germs, a few drug resistant, antibiotics kill illness which also kills good and bad bacteria, drug-resistant bacteria grows and starts to takeover, bacteria give their drug -resistance to others increasing the problem
Spatial Separation
Maintaining physical distance from individuals with respiratory infection to prevent exposure/ transmission of pathogens; if visitation with RI cannot be postponed: wear a mask, perform hand hygiene, avoid common areas, restrict visit to just resident's room, keep visit brief - staff can demonstrate how to cover a cough, assist with wearing a facemask, identify supply locations, send letters to families to educate them on the cold/flu season with presentations and handouts
Meters
Makers for device to consider: design features, capacity for cleaning population that is using the device: dedicate meters to individual residents when possible, if meter needs to be shared (clean and disinfect after each use) use recommended manufacturer instructions (if not provided, it should not be shared)
TB Environmental Controls
Measures to prevent the spread of and decrease the concentration of particles of TB in air - dilute or remove contaminated air through ventilation, secondary controls = manage airflow within or near TB to filter the air, resident with positive TB should be placed in an AIIR
Comprehensive Surveillance
Tracking every infection event (may reduce opportunities for analyzing infection data and implementing prevention)
Calculating Performance Monitoring
Tracks adherence to IPC practices (# of times practice is performed correctly/ total # of opportunities to perform practice) x 1,000 = percent adherence
Unsafe Injection Practices
Transmission of viral and/or bacterial pathogens (can potentially expose thousands of patients to bloodborne pathogens) - leads to risks of CMS certification, damaged reputations, referral to licensing boards for disciplinary action, malpractice suits filed by residents
Enterobacteriaceae (CRE)
are a large order of different types of bacteria (germs) that commonly cause infections both in healthcare settings and in communities. Examples of germs in the Enterobacterales order include Escherichia coli (E. coli) and Klebsiella pneumonia CARBAPENEM RESISTANCE
Latent TB Infection
Does not have symptoms, cannot spread bacteria to others, skin test (interferon-gamma) is usually positive, chest radiograph is typically normal and sputum exam is negative
Pocket-sized ABHR
Allows staff members to perform hand hygiene when they cannot access a wall-mounted dispensar or sink
Single-use Auto-disabling Fingerstick
Disposable, prevents reuse through auto-disabling feature (recommended in healthcare settings)

Antibiotic Time Out Policy
Documents reassessment and decisions to de-escalate or continue treatment 2-3 days after an antibiotic start
Antibiotic Resistance
Ability of bacteria to avoid killing effects in an antibiotic, results in an increase in mortality, long hospitalizations, increase in cost, using antibiotics increases risk to get resistant pathogens
Why are nursing homes susceptible to infection?
Age of residents, invasive devices, medications, functional impairment, communal living, group activities, and comorbid conditions (chronic diseases)
AIIR
Airborne Infection Isolation Room
If SARS-CoV-2 is detected...
All residents in facility should be tested - respiratory symptoms alone are not sufficient enough to identify infection - can use nasopharyngeal swab but Nucleic Acid Amplification Tests (NAATs) are preferred
Antibiotics and Unintended Harms
Allergies, side effects, drug interactions, sometimes an increase in adverse events, polypharmacy associated with greater risk of adverse events - antibiotic use for c.diff can disrupt microbiome and create an environment for resistant bacteria (increase risk for c.diff infection)
Viral Gastroenteritis
An inflammation of the stomach and intestine lining that causes stomach symptoms such as vomiting and diarrhea
AR
Antimicrobial Resistance
Fluorescent Markers
Applies to surfaces before cleaning, prescence of using special lighting, prescence after cleaning indicates not clean. Decisions about products: EPA-registered should claim hospital-grade disinfectant on the label
Steps for Surveillance

A Streptococcus
Bacteria that causes Strep Throat - spread by direct contact with discharges from the nose and throat of infected people or by contact with infected wounds or sores on the skin. The risk of spreading the infection is highest when a person is ill, such as when people have "strep throat" or an infected wound
Mycobacterium tuberculosis
Bacteria that causes tuberculosis - the bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick AIRBORNE PRECAUTIONS NEEDED

Outbreak: closed pipes (dead legs), without no water flow may contributed to Legionella growth in water systems - interventions include maintaining disinfect levels
Hand Hygiene Training
Should be offered upon hire, annually, when new products are introduced, when new policies/procedures are introduced, in response to deviations from recommended practices identified through monitoring - staff competency assessment follows, smell, consistency, color, dryness should be considered; other factors include - place in resident care areas, provide ABHR where sinks are not found, dispensar accessibility, in multi-resident rooms, and when staff input on accessibility
MRDO-Colonized Resident
Should be placed on contact precautons with consideration of a single room when there is evidence of ongoing MDRO transmission despite control efforts and when there are challenges with containing the sites of MDRO colonization
Engage PH Partners for Water Quality Concerns
Single case of Legionnaires disease, a rise in the rate of infections due to the same waterborne pathogen - health dept. can provide guidance for water quality concerns that cannot be resolved by the facility's water management team, information about waterborne infections in the community
Leg Bags
Small urine collection bags that are secured to the leg, may facilitate mobility, comfort, independence, increased risk of bacterial contamination, benefits may out weigh infection risk for some
Chain of Infection
Source of reservoir of infectious agent with portal exit, susceptible host with portal entry receptive to agent, mode of transmission for infectious agent
Pantoea aggiomerans
Species is a type of bacteria typically identified from environmental sources including water
QA of the QAPI
Specification of standards (indwelling urinary catheters)
If Unsafe Injection Practice Occurs...
Stop immediately, notify state and local health departments, notify affected resident and offer testing
Indwelling Catheter
Straight in and out, external, suprapubic, indwelling catheter-associated with infectious/ noninfectious harms
Performance Improvement Activities
Strengthen practices or helo address an IPC activity - prioritize high-risk, high-volume, or problem-prone areas, review the annual facility IPC risk assessment, review IPC surveillance
Situation, Background, Assessment and Request Recommendation (SBAR)
Structure helps to provide communication and documentation - algorithms based on published criteria can be used to determine when antibiotics should be initiated (manages infections consistent serves as a resource for antibiotic stewardship)
Line List
Summary of cases
Environmental Surface
Surfaces of resident care equipment, housekeeping surfaces (minimal hand contact - those with frequent hand contact or increasing touch)
Implanted Ports
Surgically placed, months to years, placed completely under the skin with no external parts visible, special needle used to access the port
Culture Based Diagnostic Testing
Takes time to grow the organism - normally uses a swab to collect cells from inside the mouth or nose/ uses a swab to collect pus from a wound
Incubation Period
Time from exposure to illness onset
Colonization Pressure
The higher the # of residents on a unit or facility that has an MRDO, greater the risk for uninfected residents
Bacterial Pneumonia
The leading cause of hospitalization/death in nursing home populations. Risk factors: most bacterial pneumonias develop when organisms that are colonizing the nose, mouth and throat and are contained in saliva are aspirated
Aseptic Technique
The manner of handling, preparing, and storing medications, injection equipment, supplies, syringes, needles, IV tubing, to prevent microbial contamination
Surveillance
The ongoing, systematic collection, analysis, interpretation, and dissemination of data
Airborne Transmission
The spread of an organism via droplets or dust - suspends in the air depending on infection
Resident Plan of Care
Therapy and care needs, resident safety, resident emotional well-being, minimize visitation with resident's family (communicate why precaution started, level of infectivity, the type of interaction that is okay) - PPE should be placed outside of resident's room
Resident-related Infections
UTI, pneumonia, skin/ soft tissue infections (SSTIs)
Dirty Unit
Unit on other precautions over standard precautions (ex: COVID-19 unit)
Clean Unit
Unit on standard precautions
Indirect Syringe Reuse
Unsafe practice of reusing a syringe with or without same needle, to obtain an additional dose of medications for resident -> introduces resident's blood into medication container and exposes other residents to that blood if medication from other container is administered to them
Cold Water Cycles
Use chemicals suitable for decreasing temp washing at concentrated - clean linen should be stored in areas designed to minimize dust, maintained at normal room temp and humidity ranges
Refridgerated Medications
Use in designated refridgerators, thermostat controlled, separate doors for refridgerator and freezer, keep storage log
Single-Use
Use once then discard like needles and syringes
Multi-dose Medication
Used for one or more residents may be allowed if certain precautionary practices are followed
Contact Precautions
Used to prevent transmission of infectious agents spread by direct or indirect contact - excessive excretions, extensive environmental contamination: gloves and gown donned upon entry and removed into resident's trash bin
Transmission Based Precautions
Used when standard precautions, alone, may not be sufficient enough to prevent pathogen transmission - implemented before pathogen is identified, ideally all residents put on TBP should be placed in a single room - if room is limited, prioritize patients suspected or known to have highly communicable pathogens (ex: influenza, norovirus) - if AIIR room not available, resident most likely needs to be transferred to another facility (during wait time, resident should be placed in single room and wear a facemask if cooperative)
VPDP
Vaccine Preventable Disease Program
Outbreak-related infections
Viral respiratory, viral gastroenteritis, scabies,
Hot Water Cycles
Wash with detergent at more than 160 degrees for 25 minutes
Documentation of Wounds
Wound type, location on the body, measurements, description, assessment for complications (ex: redness, swelling, drainage) every 7 days, clean supply cart should only be touched with clean hands
Staphylococcus aureus (MRSA)
about 20% of people are carriers, usually limited to skin infections, kills young, otherwise healthy individuals, has genes for toxins not found in other S, aureus strains METHICILIN RESISTANT
Enterococcus species (VRE)
formerly classified as part of the group D Streptococcus system - is a gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans, like other species in the genus Enterococcus, E. faecalis is found in healthy humans and can be used as a probiotic VANOCOMYCIN RESISTANT
