CAUTI’s (catheter-associated urinary tract
infections) and CLABSI’s (central line-associated bloodstream infections) remain
serious hospital-acquired infections (HAI’s). The best way to avoid them is to
avoid the use of urinary or vascular catheters in the first place. Fortunately,
there are good guidelines for determining the appropriateness of such
catheters. But, obviously, some are needed. The next most important facet of
preventing CAUTI’s and CLABSI’s is removal of the catheters as soon as they are
no longer needed.
Urinary catheters are the leading cause of
hospital-acquired urinary tract infections (see our many prior columns listed
below). And urinary catheters are associated with many non-infectious
complications and adverse effects, including GU trauma, reduced mobility (the
“one-point restraint”), falls, and delirium.
While we will use the term “intravascular
catheters” in this column, we are talking about central venous catheters and
PICC lines. Our prior columns on such lines (listed below) also note there are
other potential complications from these catheters besides CLABSI’s.
The University of
Michigan has been at the forefront of the campaign to eliminate CAUTI’s and
CLABSI’s. They previously reported on many of the barriers to successful CAUTI
prevention (see our June 2013 What's
New in the Patient Safety World column “Barriers
to CAUTI Prevention”).
Despite
all these efforts, we continue to see infections related to such catheters. The
Michigan team also led a multi-state quality improvement initiative aimed at
reducing CAUTI’s and CLABSI’s in ICU’s having high rates
of such infections (Meddings
2020).
But that initiative yielded no statistically significant reduction in CLABSI,
CAUTI or catheter utilization in the first two of six planned cohorts.
So, the University of Michigan group did
observations and in-person interviews with clinicians working on a progressive
care unit of a large hospital in attempt to identify barriers to timely
catheter removal (Quinn
2021). The researchers found five distinct themes related to the
organizational culture of catheter removal:
The EHR should play a critical role, but it
often does not. The researchers found that information on catheters, such as
catheter presence, when it was inserted, and the medical indication for it, was
hard to find and often not accurate in the EHR. We have always recommended that
order entry screens for catheter insertion include a field for indication (listing appropriate indications in a
checkbox format). There should be a flag set on every patient having a catheter in
place. That way, a nurse or physician can see a daily listing of which patients
have catheters in place. Moreover, clinical decision support systems can alert
clinicians to reassess the need for continued catheter use on a daily basis. The real problem arises when someone simply
takes a Foley catheter kit or intravascular catheter kit to the bedside and no
CPOE order is created for that catheter. We’ve done multiple columns
highlighting that often a clinician is “surprised” to find his/her patient has
an indwelling catheter (see our May 8, 2007 Tip of the Week “Doctor, when do I get this red rubber hose
removed?”, and
our What's New in the Patient Safety World columns for December 2014 “Surprise
Central Lines” and
July 2016 “Holy Moly, My Patient has a FOLEY!”).
Such catheters are often inserted at night by covering physicians, not recorded
in the EHR, and poorly communicated with the daytime clinician team. And we
often don’t notice the patient has a catheter because
it may be obscured by blankets or gowns. We think the solution there lies in
use of barcoding to tie the catheter to a specific patient.
Such barcoding could tie to the MAR (medication administration record) as a
means of interfacing with the EHR and require that an indication be input. Note
that we have previously also suggested that every catheter kit have a checklist
that must be filled out before use and one of the items on that checklist would
be indication. However, unless the MAR is clearly linked to the EHR and CPOE
system, someone would still have to manually input the data from that checklist
into the EHR if the EHR is to be utilized for tracking catheter use and
generating alerts.
Quinn
et al. found that catheter data in the EHR were not readily available during
morning rounds because these physician teams did not typically round with laptops
or tablets. It’s easy enough to get a printout of all
patients belonging to an individual clinician or service who have a catheter in
place. That paper printout can be taken on rounds when the rounding team is not
using laptops or tablets. Our own experience is that nurses are much more
reliable than physicians in paying attention to catheter use. Hopefully, the
rounding team includes a head nurse or other nurse who could have the printout.
The second theme, that catheter removal is
not a priority, is perhaps the most important barrier. The researchers found
that both physicians and nurses are very busy
attending to multiple medical problems in multiple patients and often attention
to catheters falls to the bottom of their list of priorities. The second part
of that theme, however, is much more problematic. That is the observation that
sometimes nurses may like having either a urinary or intravascular catheter in
place for convenience. Convenience, of course, is not a legitimate indication
for continued catheter use (except possibly in a patient receiving only
end-of-life care). Ideally, any CDSS-generated alert asking about continued
catheter use should require input of the indication for continued use.
The third theme was confusion exists about
who has the authority to remove catheters. The hospital did have a policy in
place that allowed nursing staff to remove urinary catheters without a
physician order if certain criteria were met. However, in practice, many
physicians were unaware of the policy and many nurses were reluctant to remove
the catheters without a physician order.
Theme
4 was lack of agreement on, and awareness of, standard protocols and
indications for removal of catheters. While organizations may have clearly
stated criteria for insertion of urinary or intravascular catheters, few
specifically delineate criteria for discontinuation or removal of them. Quite
frankly, we think they should be the same for initial insertion and
continuation, so each day the clinical team should be asking whether the
criteria continue to be met.
Theme
5 should surprise no one: communication barriers create challenges. The
researchers found that physicians seldom spoke to each other about catheters
and communication between physicians and nurses was particularly poor. While we
mentioned above that we expect the rounding team would have a designated nurse
participating, that was often not practical because of large nursing workloads
or timing of the rounds (rounds often being done while nursing change of shift
was occurring). The Michigan group previously reported on a more
detailed examination of communication barriers between physicians and nurses
about appropriate catheter use (Manojlovich 2019).
Quinn
et al. note that implementation of improvement efforts such as EHR reminders
and stop orders, nurse empowerment policies, and standardized protocols have
become more common. But they note one substantial unmet need: there is a
current lack of system for displaying information about catheters at the bedside in a readily visible format. Such display should indicate the presence
of a catheter, duration of use, and indication. Such a system should prompt
discussion about its continued necessity, help facilitate removal, and prompt
recognition and correction of any incorrect catheter data in the EHR.
This
is yet another valuable contribution from the University of Michigan
researchers on ways to prevent CAUTI’s and CLABSI’s (and other adverse
consequences of catheters).
