Background: Over the years antibiotics have brought many serious infectious diseases
under control and have saved millions of lives. But these gains are now seriously
jeopardized by the emergence and spread of resistant bacteria. Especially intensive care
units (ICU) worldwide are faced with increasingly rapid emergence and spread of
antibiotic resistant bacteria. Antibiotic resistance in the ICUs has made treating infections
very difficult, and in some cases impossible. It has emerged as an important variable
influencing patient mortality and overall resource use in the ICU setting.
Aim: The general aim of this pilot study was to develop and test the feasibility of a pilot
questionnaire targeting physicians´ experience on the burden antibiotic resistant bacterial
infections at their ICU.
Method: A questionnaire was developed and pre-tested. The final version was distributed
to physicians from different parts of the world. This pilot study was a cross-sectional
study with both a qualitative and a quantitative component. In total about 120 were sent
out.
Result: The results demonstrate that a majority of the respondents consider antibiotic
resistance to be a burden at their ICU monthly or more often. Of the respondents 50%
had encountered a patient that had died of an infection without any therapy options due to
antibiotic resistance. None of the respondents do never experience burden at the ICU.
Conclusion: Overall this small study has highlighted a number of alarming findings.
Antibiotic resistant bacterial infections constitute a burden at ICUs worldwide. Assessing
the implications of increasing prevalence of antibiotic resistant bacteria is important. A
larger study needs to be completed in order to get significant results.

4.1.4 Inadequate or sub-optimal antibacterial agent
The participants were asked to specify what antibacterial agent/s used on the patient that
was/were considered to be inadequate or sub-optimal. The physicians responded to this
question with one or more antibiotic, see table III.

4.2 The respondents’ point of view of antibiotic resistance All respondents, whether they encountered an antibiotic bacterial infection with no
treatment options or not, responded the questions about their opinion on antibiotic
resistance.
4.2.1 Acquired infections: hospital or community
The physicians were asked where they thought the most antibiotic resistant bacterial
infections were acquired. A majority of the respondents (29/32) answered in hospital, see
figure 7. Both the two respondents that have answered that they thought most of the
antibiotic resistant infections are acquired in community have not had a patient that had
died due to an antibiotic resistant bacterial infection.

4.2.2 Burden at the ICU
The participants were asked how often they considered antibiotic resistant bacterial
infections to be a problem/burden for the ICU. More than 19 out of all 32 respondents
experience a burden weekly or more often and 26 experience a burden monthly or more
often, see figure 8.

agents couldn’t be used due to inaccessibility at the hospital or the pharmacy. About 22
out of 32 encountered this problem rarely or never, see figure 9.

4.2.4 Too high cost for the patient
The participants were asked to answer how often they come across that adequate
antibacterial agents couldn’t be used due to too high cost for the patient. Half of the
respondents never came across the problem see figure 10. Five of the respondents came
across this dilemma monthly or more often and they were from Belgium (1), Japan (1),
Germany (1) and the Czech Republic (2). The respondent that came across the problem
daily was from Belgium. Both the two respondents that answered daily and weekly had
encountered death due to antibiotic resistant bacterial infection. Of the respondents that
had not encountered death, 27 rarely or never came across that adequate therapy couldn’t
be given due to too high cost for the patient, see figure 10.

5. Discussion
5.1 Result discussion This is one of the first studies with the aim of visualizing the burden that antibiotic
resistance imposes at ICUs. The results highlight the need for urgent action to contain the
problem, as it already today is a serious problem. Of the respondents 16/32 had
encountered a patient that had died of an infection without any therapy options due to
antibiotic resistance and a majority thought that the antibiotic resistant bacterial
infections are acquired in the hospital. Over 26/32 of all respondents (including those
who had not experienced a antibiotic-resistant relate death) stated that antibiotic
resistance was a burden for the ICU every month or more frequent, and 19/32 stated that
they experienced antibiotic resistance related burden on a weekly basis.
5.1.1 Cases where no adequate or only suboptimal antibacterial therapy was
available and the outcome was death
The questionnaire only asked about the last case of death, presumably have the
respondents that answered yes had more cases of death due to antibiotic resistance. Due
to the low number of respondents, case characteristics can not be extrapolated to a larger
patient population. It should also be remembered that the questionnaire only asked for
cases were the outcome was death, and the burden due to prolonged morbidity and
complications is not reflected in this study.
The ages of the patients that had died due to an antibiotic resistant bacterial infection,
were younger then presumed. This result was a bit surprising as the most vulnerable are
young children and the elderly with high susceptibility to infections and reduced immune
response (Nordberg 2005). But it is hard to draw conclusion about the ages when without
any background information on the patients, for example underlying diseases. None of
the patients were under the age of 16 years, this can be a result of that many hospitals
have a special unit for children.
26
Potentially high-risk antibiotic resistant bacteria are Pseudomonas, Acinetobacter and
Staphylococcus, which also the result shows to be the most common causing
microorganisms. Previous studies have shown that the most important cause of hospital-
associated infections are the Gram-negative bacteria such as Pseudomonas,
Acinetobacter, E. coli, Klebsiella (Kapil 2005).
The results show four cases where colistin was considered to be inadequate or sub-
optimal. This is alarming as colistin today is used for treatment of infections caused by
multi resistant bacteria where no other treatment is available. Colistin is among the old
antibiotics that previously have been discarded due to its toxicity and side effects but that
today is used as a last alternative. Very few physicians are experienced in its use. There is
no standardised dosing of colistin because it was never subject to the regulations that
modern drugs are subject to (Ruef 2007).
Resistance to imipenem and meropenem, which are two of the most active antibiotics to
treat Gram-negative bacteria, is also an alarming finding. Seven of the respondents (7/16)
considered therapy with imipenem and meropenem to be inadequate or sub-optimal.
Moreover, the results show two cases of vancomycin therapy failure. Therapy with
vancomycin is often seen as standard treatment for MRSA. Tigecycline is a new class of
antibiotic specially designed for antibiotic resistant infections. It was approved within the
European Union as late as 2006 (Medical Products Agency 2007). One respondent had
experienced resistance to tigecycline. One out of sixteen is a high number and it also
illustrates how fast resistance can arise. Even the few new products that reach the market
suffer from the increasing resistance.
5.1.2 The respondents’ point of view
A majority of the physicians believe that most antibiotic resistant bacterial infections are
acquired in the hospital. This was expected as all of the participants work at ICUs, which
are particularly faced with the increasingly rapid emergence and spread of antibiotic
resistant bacteria (Fridkin 2001). The hospital acquired infections, that often are resistant
to antibiotic therapy, create a dilemma where it involves a risk to be hospitalized. The
27
two respondents that answered the community is where most antibiotic resistant bacterial
infections are acquired have not had a patient that have died due to antibiotic resistance.
That might be that they don’t experience a problem at their hospitals and have another
view of the matter, which also showed in their further answers.
More than half of the respondents considered antibiotic resistant bacterial infections to be
a burden at their ICU weekly or more often. None of the respondents answered that they
never consider antibiotic resistant bacterial infections to be a burden. How the
respondents interpreted the words burden and problem are individual. The burden and
problem considered at the ICUs could both be in a medical and an economical context.
Anyhow, these are disturbing findings, but not surprising. The emerging resistance
contribute to a higher morbidity and mortality, increased risk of complications, more
expensive and complicated therapies, increased length of hospitalization, isolations of
patients (Nordberg et al 2005b). Obviously, above mentioned examples are time-
consuming for the physicians, constitute a large cost for the ward/hospital, and of course
it must be frustrating for the physician to be without treatment options for a infection that
previously could have been treated.
Antibiotic resistance increases the risk of choosing the wrong antibiotic and contribute to
time losses when the empirical therapy is in-effective. Providing appropriate antibiotic
therapy promptly is crucial for successful treatment. The three respondents that answered
that they came across that adequate antibacterial agents couldn’t be used due
inaccessibility at the hospital or pharmacy daily or weekly are from Belgium, Japan and
the United Arab Emirates. I presume that at least in Belgium and Japan it is not
impossible to get access to adequate antibiotics (if available on the market) but it is a
matter of time. It is very important to get adequate treatment as soon as possible. Two out
of the above mentioned three respondents had encountered a bacterial infection for which
no adequate or only sub-optimal anti-bacterial therapy was available or possible to
acquire, and where the outcome for the patient was death.
28
The financing of health services differs in different parts of the world. If resistance to
first-line antibiotic occur, a switch to second- or third-line is associated with higher
expenses. This can put physicians in situations where adequate antibiotics can’t be used
due to too high cost for the patient. Fifty percent of the respondents had never come
across this, but 16% came across this situation monthly or more often. They were from
Belgium, Japan, Germany and the Czech Republic. The respondent from Belgium came
across the problem daily. No further study of what kind of financing system that exists in
above mentioned countries has been conducted. Maybe due to naivety, but I didn’t expect
that patients in Europe would come across that they couldn’t receive adequate therapy
due to too high cost for the patient. Additional two other respondents, also from Belgium,
never came across this problem. The same is with a respondent in Japan that has problem
with too high costs for patients weekly while in the mean time another respondent from
Japan never come across this. The varying answer within the same countries might be
due to different financial systems at different hospitals or that the different hospitals have
patients from varying society classes.
5.2 Methodological discussion It appeared that the questionnaire was feasible and applicable. For example, very few
don’t know answers give an indication of the feasibility and the applicability of the
questionnaire. However, this study has several limitations. The results do not qualify as
quantitative statistical survey due to biased selection of participating physicians and due
to the low response rate. But the results can be seen as a description of the respondents’
views and opinions on the matter. A greater population is needed to generalize the results.
This pilot study can however give an idea about the situation.
Participation was on voluntary basis. Several limiting factors influenced the low response
rate. At the ISICEM meeting the physicians were asked to fill in the questionnaire at site.
Several of the approached persons didn’t have time or felt like to answer. It was hard to
find people with the correct inclusion criteria willing to answer. The response rate was
62% at the ICICEM-meeting. The distribution of the questionnaire by e-mail totalled in
one respondent. That is very unsatisfactory. When the questionnaire is sent out by e-mail
29
a response frequency of 20-30% is expected. Even though the physicians e-mailed were
selected through ReActs network contacts, all of whom are all committed to combating
antibiotic resistance, and through personal contacts, the response rate was low. Lack of
time is probably the major limiting factor. To increase the response rate a second
reminder could have been sent out and reminder through phone calls could have been
carried out.
5.2.1 Selection bias
Physicians attending the ISICEM meeting in Brussels don’t represent physicians active at
ICUs as a whole. The respondents that answered the questionnaire might have more
problems with antibiotic resistant bacterial infections and be more versed in the area and
thereby were willing to answer the questionnaire or vice versa. Some of the non-
respondents might not want to confess the problems. They might see it as suffer a defeat
to report about patient that have died due to an antibiotic resistant bacterial infection. Or
maybe they don’t have any problems at all and don’t see a reason to answer.
5.2.2 Interviewer bias
The interviewer could have influenced the participants. They could have thought the
interviewer expected a specific answer and thereby chosen to answer that way. To avoid
this, questions were designed so as there should not have been considerations of “right”
or “wrong” answers.
5.2.3 Recall bias
Some of the questions in the questionnaire may have been subject to recall bias. It is hard
for a physician to remember details about a specific patient. This was taken in
consideration when developing the questionnaire. The only detailed questions dealt with
the last patient that had died. Anyhow a trust was put in the respondents’ good memory.
5.2.4 Reflection of reality or not
It is impossible to evaluate whether the contributions from the physicians reflect reality
or are truly reprehensive of ICUs as a whole. The extent of antibiotic resistance varies on
30
a global, regional and even institutional basis. Local differences can be as great as
differences between countries. A respond from one physician is not reprehensive for
her/his country or city. This descriptive study of the physicians that responded – doesn’t
reflect ”reality”, although the respondents do reflect their reality.
5.2.5 Cause of death
The type of outcome examined in this study was in-hospital mortality only, which is
relatively easy to define. But did the patient die of the infection or the infection due to
antibiotic resistance? Maybe the patient would have died anyway. It is very hard to tell
when antibiotic resistance is not a disease itself. The absence of evidence is not evidence
of absence.
31
6. Conclusion Overall this small study has highlighted a number of alarming findings. Antibiotic
resistant bacterial infections constitute a burden at ICUs worldwide. The result from the
questionnaire implicate that 50% of the respondents considered antibiotic resistant
bacterial infections to be a burden at their ICU weekly or more often. Assessing the
implications of increasing prevalence of antibiotic resistant bacteria is important. A larger
study needs to be completed in order to get significant results.
32
7. Future recommendations
- For future studies another distribution strategy is desired. Distribution of
questionnaires through personal meetings, at congresses for example, via
professional associations and other organizational networks could hopefully
increase the response rate and also improve the uneven selection of participants.
Distribution via mail instead of e-mail can be considered. Presumably, it is easier
to ignore e-mail than mail. Though, it makes it more complicated and more
expensive to send out mails rather than e-mails.
- Data on how antibiotic resistance is affecting clinical practice today is urgently
needed, in order to guide decision makers, health care professionals and the
public. The questionnaire developed in this study can be used as a model in future
more extensive research.
- Further development of the questionnaire can be considered.
• divide the question about burden into two parts; medical burden and
economical burden.
• add a question about prolonged morbidity and other complications.
• add a question about approximately how many cases of mortality due to
antibiotic resistance a year. But no detailed questions about those cases.
