Personal Disclaimer

I think I’m very funny, not everyone

thinks I’m funny.

I am a glass half empty girl. I look for the

undesirable outcomes.

Multiple challenges obtaining data

regarding peripheral outcomes.

Google Scholar.

Included data/ discussion of any type if

infection associated with short peripheral

catheters.

Excluded any data on mechanical and

chemical causes of phlebitis.

Intravenous Catheters and

Infection

Intravenous (IV) catheters are now

reported to be the single most common

source of bacteremia and fungemia. (1)

1.7 billion sold annually worldwide.

330 million sold annually in the USA.

Page 7: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

National Healthcare Safety Network

(NHSN)

Voluntary submission of infection data

for CDC.

Includes data on any vascular access

device.

Addresses both patient and healthcare

worker safety.

Page 8: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

National Healthcare Safety

Network (NHSN)

Central Line Associated Bloodstream

Infections (CLBSI) are addressed.

Tip location in the SVC/ CAJ

Definitions include:

CVAD present 48 h before S&S develop

Not related to any other infection site

Page 9: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

National Healthcare Safety

Network (NHSN)

No mention of surveillance on Vascular

Access Devices (VAD) within the

peripheral vessels.

- Yet these devices are part of the

reporting system.

Page 10: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

CRBSI

CRBSI- laboratory findings that identify

CVC as BSI source and used to

determine diagnosis, treatment, and

possibly epidemiology of BSI in patients

with CVC.

Not typically used for surveillance (more

in clinical research).

Page 11: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

CLBSI

CLABSI- laboratory confirmed BSI only

requires a CVAD to be present with in 48

hrs of S&S and it not be related to any

other source.

Not a rigorous criteria. May lead to an

overestimation of the actual rates.

These rates would NOT include infection

from a short peripheral catheter.

Page 12: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Financial Implications

2008 Medicare & Medicaid Services

disallowed payment for certain hospital

acquired conditions.

List included vascular catheter-

associated infections.

No clarity on type of catheter, location of

catheter.

No clarity on type of infection.

Page 13: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Financial Implications

Nosocomial BSIs reported to be the 8th

leading cause of death in the US (3).

$23,242 +/- $5184 (2005 dollars) (3).

Page 14: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Financial Implications

Hospital must prove the infection was

present or incubating on admission.

Page 15: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Financial Implications

Hospitals participating in NHSN system

has no formal way to document

infections related to peripheral IV.

No real incentive as these would be

considered hospital acquired with no

payment to the hospital for their

treatment.

Page 16: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

What's the Big Deal?

3 cases- Osteomyelitis.

5 cases- Cardiac Implantable electronic

devices (24).

2 cases- Peritonitis in PD catheters (25).

4 immunocompromised oncology pt with

probable cutaneous zygomycosis from

adhesive tape on a peripheral catheter (26).

Page 17: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

CDC Guidelines

Center for Disease Control (CDC) 2011

does include peripheral catheters.

However, the discussion section only

includes CVADs.

Includes a table of catheters for venous

and arterial, but states “rarely associated

with bloodstream infection.” 2(p22)

Page 18: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Types of Infections

Local: cellulitis and

soft tissue.

Page 19: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Types of Infections

Phlebitis or thrombophlebitis

Page 20: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Types of Infections

Suppurative thrombophlebitis: presents

of purulent drainage.

The clinical S&S may overlap making it

difficult to identify the problem without

additional diagnostic tools such as

ultrasound and cultures.

Page 21: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Phlebitis

Definition: inflammation of the vein (4)

Nursing/ medical literature describes 3

causes:

Chemical

Mechanical

Infectious

Page 22: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Chemical

Infusion of

hyperosmolar fluids

(>600 mOsm/ liter)

and/ or solutions and

medications with a

pH <5 or >9.

Page 23: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

pH

Indicates hydrogen

ion concentration in

a solution

Blood = 7.35 - 7.45

pH of 6 - 8 minimizes

disruption of venous

endothelium

Blood has significant

buffering capacity

Page 24: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Mechanical

Catheter size,

insertion technique

and methods of

catheter and joint

stabilization.

Page 25: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Infectious

Deficits in skin

antiseptics, catheter

handling and joint

stabilization.

Page 26: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Confusion?

This leads confusion about whether the

inflammation allows for the infection, or if

the infection creates the inflammation.

Page 27: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Cherie’s Opinion

All three contribute to infection.

Page 28: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Maki, Systematic Lit Review

(2006)

January 1966-July 2005 (38.5 yrs).

110 studies of plastic catheters.

10,910 catheters; 28,720 device-days.

13 BSIs= pooled mean rate 0.1 event

per 100 days.

0.4 pooled mean events per 100 device days.

Lowest rates of all devices by percentage. (23)

Page 29: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Culture Results

Most prevalent pathogen in peripheral

catheters BSI is Staphylococus aureus (5-

7).

Retrospective analysis of all US hospital

admissions estimate > 10,000 S. Aureus

bacteraemia from peripheral catheter

occurring annually(8).

Page 30: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Rates of each type of Infection

Zingg and Pittet (6) widely held

assumption that thrombophlebitis can

become BSI.

They estimate 5%-25% of peripheral

catheters were colonized at the time of

removal.

Reasons for the low BSI rate vs high

colonization- short dwell time, fewer

manipulations and lack of surveillance.

Page 31: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Issues Related to BSI

Catheter design,

Skin Antiseptic,

Inserters skill level,

Predisposition to phlebitis,

Use of vein visualization technology,

Catheter stabilization.

Page 32: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Sources of Contamination

Page 33: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Catheter Design

Ported catheters- multiple injection ports,

or ones with non-replaceable caps.

Page 34: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Injection Ports

Attachment of stopcocks known risk for

infection.

Germany study reported 27 BSI cases

per 100 patients, 104 events per 1000

catheter days.

27% of patients experiencing possible

infections, there is little doubt about the

risks of injection ports. (11)

Page 35: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Infusion System

One hospital in London had 30 reported

MRSA bacteremia's. Changing to a

closed system decreased rates to 14

MRSA bacteremia's.

BUT...Also introduced split septum, CHG

along with other policy changes and a

massive educational campaign.

Page 36: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Microbiology of the Skin

80% of the

resident bacteria

exist within the

epidermis.

20% are found in

biofilms within hair

follicles and

sebaceous

glands.

Complete re-

colonization can

occur within 18 hrs of

antiseptic application

Page 37: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Skin Antisepsis

Primary source of organisms colonizing

the IV catheter comes from the skin.

Careful attention to the antiseptic agent,

method of application and the total

contact time for application and drying.

Familiarization of the various products

and their uses directly contributes to their

effectiveness.

Page 38: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Antiseptic Agents

Traditional teachings

involved inner/ outer

concentric circles.

This typically

involved simply

painting the skin.

Three impregnated

sticks.

Page 39: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

CHG

Use of a back and forth scrubbing

method (Manufactures IFU).

Only 1 published study available on the

application technique .(12)

Several studies show CHG produces

better outcomes for blood donation and

blood culture collection. (14-17)

Page 40: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Best Practice Guidelines

Infusion Nurses Standards and CDC

(2011) states CHG is preferred skin

antiseptic (except infants less that 2

months).

Tincture of iodine, iodphor, and 70%

alcohol are also acceptable for short

peripheral catheter insertion.

Both state should be applied to CLEAN

SKIN.

Page 41: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Infectious Disease Society of

America (IDSA)

These list alcohol, tincture of iodine, or

alcoholic CHG as acceptable.

State povidone-iodine is not adequate.

Emphasizes the need for adequate

contact and drying time. (18)

Page 42: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Inserters Skill Level

Two studies assessed the skill of

inserters.

One reported ER nurses had a greater

phlebitis rate than IV therapists (3.7% vs.

2.1%). (13)

Second reported 36% inserted by

generalists and 20% by infusion nurses

were removed for complications. (19)

Page 43: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Predisposition to Phlebitis

Pt experiencing phlebitis with the first

catheter were 5.1 times more likely to

suffer from phlebitis from subsequent

catheters. (19)

Why?

Is related to the infusions?

The insertion site?

The skill of the inserter?

Page 44: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Use of Vein Visualization

Technology

Infrared and ultrasound

Page 45: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Infrared

Infrared is hands free.

No change in technique for insertion.

Does not touch the patients skin.

Page 46: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Ultrasound

Widely available in most hospitals.

Requires one hand to hold the probe.

Coupling gel.

Page 47: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Ultrasound

CVAD insertions: sterile procedure

covers and sterile coupling gel.

Short peripheral catheter insertion is not

considered sterile.

Page 48: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Mini Ultrasound Equipment

- Smaller, portable

equipment

- Individual, sterile probe

tips.

- Assists in determining

vessel size,

appropriateness of

catheter

Page 49: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Disadvantages

Formal education not available.

Healthcare workers picking up the device

and using it.

Poor site selection

Poor vessel: vein ratio

No training on anatomy (nerve identification)

No peripheral infection data reported on

any vein technology.

Page 50: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Catheter Stabilization

Gained attention

over the past 15 yrs.

Initially advertise to

replace sutures.

Studies showed

decrease in

unplanned restarts,

no data on infectious

outcomes. (20)

Page 51: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Tape

Tape is not sterile

- Pockets, on bedside

tables, on IV poles,

window etc.

- The adhesive picks

up fuzz, bacteria and

other debris.

- NEVER place this

under a sterile

dressing.

Page 52: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Time in Situ

Prior to 2011, all documents

recommended routine removal/

replacement after a specific dwell time.

The length of time was increased from

48 hours to 96 hours.

CDC revised wording states “... No more

frequently than every 72-96 hours for the

purpose of reducing infection...”

Page 53: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

INS, 2011

Removed the routine removal

recommendation.

“The nurse should consider replacement

of the short peripheral catheter when

clinically indicated...” 4(pS57).

Page 54: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Scrub the Hub

When you access a

catheter to

administer

medications, change

the end cap, or flush

the catheter. You

can inadvertently

introduce micro-

organisms into the

catheter.

Page 55: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Flushing Techniques

- Use of a 5-10mL syringe

- Do not use the pump to

flush your catheter

- It is the pressure exerted

from a syringe that really

forces fluid through the

device and clears it of

blood and residual

drugs.

Page 56: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Cherie’s Opinion: Education

Inserters skill level directly influences

success rate, increases longevity of the

device and decrease infection risks.

1-3 hours spent in traditional classroom

theory surrounding infusion therapy.

3-10 hours spent in “lab” type

environments.

Opportunity to develop skill fragmented.

Page 57: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Cherie’s Opinion: Skill Level

No literature supporting a required

amount of time or XX number of

insertions before becoming proficient.

I estimate 3 months, full time hours on

VAT before advancing beyond “novice”.

Average of 10 “insertions” day, can be

40/week. 3 months = 480 ish.

The generalist nurse may get 2/wk= 25

ish in the same time period.

Page 58: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Vascular Access Specialized

Training

Education on skin cleansing agents.

Education on dressing material and

application.

Education on solutions/ medications (pH

and osmolarity).

Education on vessel assessment.

Education on vessel preservation.

Admit when you are licked.

Page 59: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Protect the Skin

The skin or integument is the first organ

affected by vascular access.

It is a barrier against micro-organisms

and provides sensory temperature

regulation.

Inserting an intravenous device breaks

this natural barrier and

increases the risk of infection.

Page 60: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Nursing Assessment

Measure twice, cut once.

Site selection aides in the longevity of

the device.

CDC states “In adults, use an upper-

extremity site for catheter insertion.

Replace a catheter inserted in a lower

extremity site to an upper extremity site

as soon as possible.” Category II (2)

Page 61: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Insertion Sites

Nursing textbooks recommend starting

low on the extremity and moving

upwards

Page 62: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Site Selection

Perhaps this is

related to the low

success rate on

the first attempts

necessitating the

need to go above

previous

insertions?

Page 63: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Device Selection

Smallest device, in the biggest vein for

the desired therapy.

“Go big, or go home...”

7 rights of medication, 7 IV rights

Appropriateness of request.

Device size, (diameter/ length), design,

need.

Insertion site, vessel size (diameter/ length),

health.

Page 64: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Nursing Assessment

Consideration regarding the use of the

device is upmost importance (i.e. CT,

Chemo, pre-op, blood transfusion etc.).

This determines site selection, gauge

and even appropriateness of the

need/request.

Page 65: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Blood Flow

Blood flow to the

hand is approx. 10

ml/ minute.

Multiple small, short

vessels.

Subject to movement

due to decreased

tissue/ muscle in the

hand.

Page 66: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Blood flow

Forearm vessels offer

a longer, straighter

pathway.

Higher blood flow for

greater dilution.

Bones of the ulna and

radius act as natural

splints which allow for

freedom of movement

and greater

independence.

Page 67: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Danger Zone

Devices placed at or

about the wrist area.

Must be a minimum of

two fingers above the

bend at the wrist.

Can take up to 3 months

for the numbness to

resolve.

Many suffer permanent

nerve damage.

Page 68: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Dressing

Decreases the

movement within

the vessel.

Page 69: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Documentation

Often overlooked and poorly done.

Must include:

All attempts.

Site location (vessel name, description).

Gauge/ length of catheter.

Cleansing agent.

Add on equipment.

Blood returns/ flushing.

Patients tolerance.

Page 70: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Summary

Numerous practice changes in 30 yrs.

Sicker patient population, living longer.

Improved skin cleansing agents (CHG).

Removed teams with highly skilled

infusion nurses, giving this task to

primary care/ generalists.

Page 71: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Summary

330 million IV catheters sold in the US.

Venipuncture success rates of 2.18

attempts (21) and 2.35 attempts (22) to

establish one site.

If ½ the catheters sold are successfully

inserted, 0.1% of these produce a BSI.

165,000 infections annually.

Clearly, more research is needed.

Page 72: Short Peripheral IV Catheters and Infections - IPAC MB · PDF fileShort Peripheral IV Catheters and Infections ... Attachment of stopcocks known risk for infection. ... the IV catheter

Cherie’s Opinion

Devices/ equipment do

not directly cause

infection.

People cause infection.

Protect the skin.

Follow the Best

Practice Guidelines.

Follow the

Manufacture’s IFU.
