Twitter site was used to asnlyize 52,153 updates which mentioned antibiotics between March 13, 2009 and July 31, 2009.

Tweets were categorized into 11 categories:
1. general use. Most common category. Ranged from updates about antibiotics, days needed to be on antibiotics, and how long before they start to work
2. advise/information. 2nd common transfer of personal advice and information
3. side effects/negative reactions. 3rd common . General comments about how antibiotics made them feel to not being able to drink alcohol or sun sensitivity.
4. diagnosis
5. resistance
6. misunderstanding or misuse. This compromised 700 of the 52,000 tweets. These could spread to large audiences.
7. positive reactions
8. animals
9. wanting and needing
10. cost
11 other

This review of Twitter shows that misinformation can be disseminated to quickly and to thousands of people.
Tjis study showed that social media sites need to be monitored contantly and explore wayshow they can positively impact public health.

Targeting Zero

A philosophy that every healthcare institution should be working toward a goal of zero healthcare acquired infections.
It is understood that not all HAIs (hosital acquired infections) are preventable.

APIC (association for Professionals in infection control) ofers many courses, webinars, and guidelines how to study and track HAIs.

The importance of surveillance with HAIs cannot be emphasized enough.
There are manual systems and computer generated systems.
I personally work on the manual system. My company which has many hospitals does not
have in place a computer generated infection control surveillance.
My hospital has an electronic medical record. Radiology, pharmacy, nursing, medicine, and
rehab are all included in this record. The lab system is an independent computer
system.

By manually collecting data one must:
check lab workdaily
correlate antibiotic therapy to labwork
count IV and PICC line days and number of patients and calulate out
count foley catheter patients and foley catheter days and calculate out
manually watch HH and PPE and calculate satistics
make sure every patient admitted to the hospital has lab work to allow for continuity
of care


It takes a team to target zero. Everyone who takes care of a patient is included. From
the dietary aide to nurses aide, to nurse, and physician.

enterobacteria resistance to the class of antibiotics called carbepenems

Who are enterobacteriaceae?

Large group of gram negative rods that inhabit human large intestine, soil, plants, and water.
They grow equally well in air (aerobic) and without air (anerobic).
Most common enterobacteri that are found in hospitalized patients and causing disease are:
eschericia coli, Enterobacter cloacae, Klebsiella pneumonia, Serratia marcesens, and roteus mirailis.

Enterobacteriacae rarely infect patients that are not immunocompromised. Which means the host defenses must be breached in order to cause infection therefore illness.
How does this occur? surgery, IVs, tube feedings, burns, ulcers, breaks in the skin, and contaminated food or beverages.

Enterobacteriacae can be resistant to first generation cephalosporins such as cefazolin and cephalexin. Cephalosporins work by killing bacterial cells by imparie cell wall synthesis. This is done by preventing the cross-binding of the peptoglycan polymers neecessary for cell wall formtion. The most comon form of antibiotic resistance from enterobacteria are the production of beta lactimase which can destroy the beta lactam ring by hydrolysis therefore prevent antimicrobial activity. Theses are known as the ESBL's.

They are a common source of infections in the hospitalized patient. Repeated use of antibiotic drug specific to the infection, and empirical Use before culutres are done) use have cause these enterobacteriaceae in some patients to become very resistant to treatment.

What are carbepenems?
They interfere with cell wall synthesis by pinding to penicillin-binding proteins (PBPs) enzymes which are essential for cell wall synthesis

Spectrum of activity;
It is due to the PBPs of bothe gram negative and gram positive bacteria.

Carbepenes are: Imipenem, merepenem, ertapenem

Why is there a concern with this class of medications?
Enterobacteriaceae are now becoming resistant to this class of drugs.
This is our last line of defense against infections in some patients. There is no other treatment.

Pharmaceutical companies are not investing time and money into antibiotics becasue resistance occurs faster than drugs are worked on.

So how to we prevent the spread of these resitant enterobacteriaceae?

Hand hygiene.

Contact precautions

Dr. Carnelli from Tel Aviv Hospital, Tel Aviv, Isreal is an epidemiologist working their. They had an outbreak several year ago. He had 2 patient floors set aside for CPC patient. He halso had dedicated staff to those floors . Which means the staff did not work anywhere else in the hosptal. Equipment did not leave the floor. There were special exceptions: such as the patient who needed ICU care. It took about 2 weeks for nonew cases of CPC to develop. (The did genotyping on all the CPC detected). The hospital remained CPC free for about 6 months. Dr, Carnelli then looked at where the patients were coming from. Those patients coming from skilled facilities where their exposure to the healthcare system was higher, had a high incidence of CPC. Therefore every patient entering Tel Aviv hospital is now screened for CPC.

At the kindred hospital where I work and our sister site, patient who develop CPC are placed in a private room, with very strict precautions.

There is a correlation between the hospital environment and hospital acquired infections. Enironmental services(ES), housekeeping.

Must understand disease transmision; droplet, airborne, fomite, vector

Organisms in the environment: MRSA, VRE, C Diff, serratia, pseudamonas, staph aureus, strep

Idenify patients on admission.

Cleaning a hospital room: needs 10 minutes for cleaning solutions and contact time
also have to consider all posible high touch areas - bedside table, light switches,
overbed table, remote control and call bell, door knobs; electronic media equipment


see CDC website for picture of Hospital room with terminal clean that cultured positive.


Have to know if C diff has been in the environment, need to use -10 bleach solution.

Products: Phenols, quats, bleach pay attention to exact measurments


Housekeeping - environemental services - much feel a apart of the hospital team. Need the correct tools. Right education and orientation to the hospital environment. Need respect and connection to purpose.

Best Practices in the Sterile Processing Department (STP)

4th annual conference from Infection Control Today: Virtual Conference of Professional Development
Febray 9-10, 2010

Best Practices in the Sterile Processing Department (STP) by Nancy Chobin, RN, AAS< CSPDM


Guidelines from AAMI and AORN

STP was always the department that was not thought of. Today it is a major player in the hospital.

STP scrubs; physical barriers to this department. Controlled temperature 60-65oF and humidity controlled between 30-60%; and a negative pressure room with less than 10 air exchanges/hour.

clean equipment with reusable brushes; correct detergent or enzymatic cleaner - measure amounts correctly.

Regulatory agencies AAMI and AORN require weekly testing for effectiveness

This inistial cleaning is to reduce biofilm formations and debris left after decontamination

Have to know the water quality and temperature. The correct temperature needs to be used with enzymatic cleaners. If the temperature is too high the enzymatic detergent can be killed, if the temperature is too low the enzymatic detergents can be slo=uggish.

Standard Precautions used in the SPD. Need water repellent gowns and gloves.

Must know how to load sterilizers for optimal cleaning. Each pack has an expiration date on the outside of the package. One time use products should never be cleaned and reused.

Sterilization: steam must contact all surfaces in the packged equipment.
there are special cycles be aware of those peices of equipment that require this.

Ethelene oxide gas: minimal heat and aeration time

There are now infrared thermometer guns check the temperatures on packages.

Storage of sterilized equipment: 2" from outside wall; 8-10" from floor; 18" from ceiling

Process improvement: monitor compliance; PPE use; hand hygiene; loading sterilizers; packaging audits; audit of cleaning and sterilization cycles

There should be good communication between the SPD, OR, and the infection preventionist.



First always process equipment according to the manufacture's instructions for cleaning

BSI realated information

AJIC (American Journal of Infection Control)
March 2010 Volume 38 Number 2, pages 149 - 153

PICCAs (Peripherally Inserted Venous catheters) are a safe alternative to high-risk short term CVC (centrally insered vebous catheters).

Authors: B Rait,MD;M Fakih,MD MPH; N Bryan-Nomides, MT MS; D Hopfner, RN; E Riegel, RN; Trudy Nenninger,RN; J Rey, MT(ASCP);S Szpunar,PhD; Detroit, Michigan


Background: PICCs serveas an alternative to short term CVC for provining IV access in the hospital setting. It is not clear which device has a lower risk of CLABSI( Central line associated blood stream infection). Comparision was made between PICC and CVC related CLABSI rates.


Results: 638 cvc were placed for a total of 4917 catheter days, of which 12 patients had CLABSI for a rate of 2.4/1000 catheter days (12 divided by 4917 x 1000)

A total of 622 PICCs placed for a total of 5703 catheter days of which 13 patients had CLABSI for a rate of 2.5/1000 catheter days (13 divided by 5703 x 1000)

The median time for a patient to develop a CLABSI with a PICC was significantly longer 23 days vs 13 fo CVC

Conclusion: the infection rate with PICCsand CVCs was about the same, but the length pof time for a CLABSI to develop was almost doubled. Therefor a PICC may be a better and safe choice for prolonged inpatient IV access.

Effectivenes of antibiotic use

APIC February 2010 Volume 38 Number 1, pages 38 -43

Effectivenss of drug use evaluation and antibiotic authoriation on patient's clinical outcomes, antibiotic consumption, and antibiotic expenditures

authors: P Rattanaumpawan, P Sutha, V Thamlikitkul (Bangkok, Thailand)

Background: zosyn,imipenem, and merepenem were inappropriately used in 50% of hosptialized patients. Hospital administrators implemented drug use evaluation (DUE) and antibiotic authorization for the abpove mentioned antibiotics beginning AUgust 2007. The objective of the study was to determine the effectiveness of antibiotic authorization on patient's clinical outcomes, antibiotic consumption, and antibioitc expenditures

Results: The patients who received antibiotic authorization had more favorable clinical outcomes (68.9% vs 60.5%) shorter duration of target antibiotics (7.5 days vs 9.3 days)
and lower mortality because of infections (29.4% vs 35.4%) than those who did not receive antibiotic authorization.

The costs of target antibiotics and all antibiotics in the authorization group were much less than those in the no-authorization group. The annual antibiotic cost savings from DUE can be figured out to $862,704.00

Conclusion: DUE and antibiotic authorization are effective strategies in reducing antibiotic consumption and expenditures, without compromising patient outcomes.

prevent antibiotic resistance

12 steps to prevent hospitalized adults

Prevent Infection

vaccinate hospitalized adults

get the devices out:

foley catheters, lines of all kinds - peripoheral IVs, invaisive lines - alines, swans, central

lines, triple lumens,PICCs, dialysis catheters; feeding tubes; tracheosotomy tubes

Diagnose and Treat Infections Effectively

Use appropirate methods for diagnosis

Target the pathogens - if UTI treat with oral agents for 3-5 days

BSI IV route better

Acess the experts:ID consults

Use Antimicrobials Wisely

Practice antimicrobial control - judiciously use antibiotics for appropirate infections not

colonizations

Use local data - antibiograms show with microbes are problems in your hospital

Treat infection, not contamination or colonization

Stop treatment: emperic antibitotic treatment should be reevaluated in 3 days to continue

or stop

Prevent transmission

Practice infection control - appropirate cohorting if need be

private rooms

isolate out MDROs from general hospital population

Practice hand hygiene and personal protective equipment (PPE)

Wash hands, wash hands, wash hands - cannot be said enough

PPE - appropirate to care - to prevent staff from transmitting microbes to other

patients and staff.

Equipment disinfection - prevent microbe spread

What is a LTAC?

What is an LTAC?

"www.kindredhealthcare.com/what-we-do/ltac/"
according to Kindred Hospital Corporate web site

Their LTACs provide specialized aggressive interdisciplinary care to medically complex patients who required extended recovery time. These patients are ill and have few options left, they come to Kindred because they requiure the aggessive and specialized care and prolonged recovery time that short term acute care hospitals cannot provide or are equipped to handle.
