Expectations, experiences and attitudes of orthopedic patients undergoing arthroscopic cruciate ligament reconstruction toward postoperative pain and its management.
ABSTRACT To evaluate expectations, experiences, and attitudes of orthopedic patients undergoing arthroscopic cruciate ligament reconstruction in terms of postoperative pain and management.
This prospective study involved 115 patients. Preoperatively, patients completed a preoperative questionnaire regarding expectations toward postoperative pain and management. Postoperatively, they completed a postoperative questionnaire regarding exact pain experiences and attitudes in relation to their pain and management.
Almost all expected (95.6%) and experienced (98.3%) pain. The median values of maximum and average pain measured by a verbal numerical rating score were 7.7 and 5.6, respectively. Approximately 3/5 reported marked and maximum relief from analgesics received Only one patient was not satisfied with pain management while the rest were satisfied in varying degrees. A large proportion showed incorrect conceptions concerning postoperative pain and management.
Postoperative pain management is still an area for improvement. Misunderstandings of patients should be explored and corrected as they can pose a barrier for effective pain relief Pain management should begin with preoperative explanations and advice followed by good care intraoperatively and postoperatively.

ABSTRACT: The objective of the survey was to assess the status of acute pain management in U.S. hospitals and attitudes of adults in the U.S. toward postoperative pain management, information that has not been previously available. Two telephone questionnaire surveys were conducted U.S. hospital participants, including 100 teaching hospitals (acute care hospitals with a residency program and/or university affiliation), 100 nonteaching (community) hospitals with fewer than 200 beds, and 100 nonteaching (community) hospitals with 200 beds or more were interviewed regarding current and future pain management programs and related topics. Adult participants in 500 U.S. households were interviewed on attitudes and experiences with postoperative pain and its management. Forty-two percent of the hospitals have acute pain management programs, and an additional 13% have plans to establish an acute pain management program. Seventy-seven percent of adults believe that it is necessary to experience some pain after surgery. Fifty-seven percent of those who had surgery cited concern about pain after surgery as their primary fear experienced before surgery. Seventy-seven percent of adults reported pain after surgery, with 80% of these experiencing moderate to extreme pain. Despite a growing trend in pain management, increased professional and public awareness including the establishment of pain management programs and public and patient education is needed to reduce the incidence and severity of postoperative pain.Anesthesiology 12/1995; 83(5):1090-4. · 6.17 Impact Factor

ABSTRACT: Postoperative pain can have a significant effect on patient recovery. An understanding of patient attitudes and concerns about postoperative pain is important for identifying ways health care professionals can improve postoperative care. To assess patients' postoperative pain experience and the status of acute pain management, we conducted a national study by using telephone questionnaires. A random sample of 250 adults who had undergone surgical procedures recently in the United States was obtained from National Family Opinion. Patients were asked about the severity of postsurgical pain, treatment, satisfaction with pain medication, patient education, and perceptions about postoperative pain and pain medications. Approximately 80% of patients experienced acute pain after surgery. Of these patients, 86% had moderate, severe, or extreme pain, with more patients experiencing pain after discharge than before discharge. Experiencing postoperative pain was the most common concern (59%) of patients. Almost 25% of patients who received pain medications experienced adverse effects; however, almost 90% of them were satisfied with their pain medications. Approximately two thirds of patients reported that a health care professional talked with them about their pain. Despite an increased focus on pain management programs and the development of new standards for pain management, many patients continue to experience intense pain after surgery. Additional efforts are required to improve patients' postoperative pain experience. IMPLICATIONS: A survey of 250 US adults who had undergone a recent surgical procedure asked about their postoperative pain experience. Approximately 80% of patients experienced pain after surgery. Of these patients, 86% had moderate, severe, or extreme pain. Additional efforts are required to improve patients' postoperative pain experience.Anesthesia & Analgesia 09/2003; 97(2):534-40, table of contents. · 3.42 Impact Factor

ABSTRACT: To assess the postoperative pain and pain medication experiences of Canadians. Three hundred and five general population subjects from across Canada who had surgery in the previous three years were retrospectively questioned regarding pain experiences in the surgical facility and at home, pain medication efficacy and pain medication satisfaction. While in the surgical facility, pain was experienced by 68% of patients who expected overnight admission ("inpatients") and 49% of patients who expected same-day discharge ("outpatients"). Overall, 47% of inpatients and 15% of outpatients reported that their highest experience of pain was severe or extreme; 25% of inpatients and 9% of outpatients reported that their average pain was severe or extreme. In the two weeks post-discharge, 79% and 74% respectively of inpatients and outpatients experienced pain. Severe or extreme pain occurred at home in 25% of inpatients and 28% of outpatients; average pain was severe or extreme for 9% of inpatients and 12% of outpatients. Complete or a lot of pain relief was experienced by 54% to 72% patients who received pain medication; higher rates of pain medication satisfaction were reported than rates of pain relief from pain medication. Severe or extreme pain was experienced by many surgical patients. Improvements could be made to patients' postsurgical pain experience in Canada, both in the surgical facility and subsequent to discharge.Canadian Journal of Anaesthesia 01/2003; 49(10):1053-6. · 2.50 Impact Factor

Postoperative pain management
Although postoperative pain is common and
pain management has much improved, studies from
many countries(1-9) revealed consistent results of
insufficient postoperative pain relief. The problem is
Inadequately treated postoperative pain leads
to a considerable number of adverse consequences
physically and psychologically(10-12). Recovery is one
of the dimensions affected by postoperative pain,
and inadequate acute pain management can affect
negatively on the long-range quality of life(13). Acute
pain can also evoke long-term neuronal remodeling
and sensitization of the central nervous system(10).
Severe acute postoperative pain is one of the risk
factors predisposing to chronic postsurgical pain
(CPSP)(14-16), which has a substantial impact on quality
of life, and treatment of chronic pain is more time-
consuming and costly(17).
Optimal postoperative pain relief is not only
based on analgesics and interventional techniques(18),
but is also tied to patients’ attitudes and beliefs, and
cooperation(19). The present study aimed to evaluate
patients’ preoperative expectations toward post-
operative pain and its management as well as their
actual postoperative pain experiences and attitudes
regarding postoperative pain and management. The
results of this will be utilized to improve postoperative

Material and Method
The present study was performed in the
university-based medical school in the southern part
of Thailand, which is also the tertiary care center for
the region. The research scheme was approved by the
faculty ethics committee. Each participating patient
signed an informed consent form before entering the
Patients undergoing arthroscopic cruciate

Within 72 hours prior to their scheduled
operation, each patient was contacted via telephone
to answer a preoperative questionnaire regarding
demographics, expectations toward postoperative
pain, the level of expected pain at which the patient
would request analgesics, and the expected extent
of pain relief from analgesics received. Twenty-four
hours following surgery, while the patients were still
admitted in the hospital, each patient completed
a postoperative questionnaire regarding their
actual pain experiences, analgesic requirements, and
pain relief effects. The second questionnaire also
comprehended items determining the patients’
attitudes toward postoperative pain and management,
together with whether they were satisfied or dissatisfied
with the provided pain care, and reasons for their
Data of the present study were recorded
with Epidata version 3.0 and analyzed using Program R
Demographic data were demonstrated as
percentages, median, mean, range, and standard
deviation. Levels of pain were measured using a verbal
numerical rating score [VNRS (0-10)] and a categorical
[verbal descriptive score (VDS)] rated as very mild,
mild, moderate, severe, and very severe.
Patients’ demographic data
One-hundred and fifteen patients participated
in the present study. The majority (102 in 115, 88.7%)
were male. The mean age was 31.8 years (range of 17 to
51). Seventy-eight patients (67.8%) had no history of a
previous operation. The average duration of surgery
was 62.2 minutes. Spinal anesthesia was performed
in nearly all of the participants (113 in 115, 98.3%)
while general anesthesia was carried out in the rest.
Postoperative pain relief was managed on an as-needed
basis with paracetamol, non-steroidal anti-inflammatory
drugs, morphine, or fentanyl.
Almost all (110 in 115, 95.6%) patients
expected postoperative pain. Their average expected
pain as measured by the VNRS was 5.7, and by the
VDS indicated 1.7%, 10.4%, 62.6%, 24.4%, and 0.9%
anticipated very mild, mild, moderate, severe, and very
severe pain, respectively.
The patients predicted they would ask for
analgesics when their VNRS reached 6.5, with 4.4%,
42.6%, 37.4%, and 15.6% estimating to request
analgesics when they had mild, moderate, severe, and
very severe pain, respectively.
Nearly all (113 in 115, 98.3%) actually
experienced postoperative pain with a median
maximum VNRS of 7.7, with 1.7%, 4.4%, 14.8%, 54.8%,
and 24.3% indicating they experienced pain at very
mild, mild, moderate, severe, and very severe levels,
respectively. The median average VNRS the patients
experienced was 5.6, with 2.6%, 13.0%, 45.2%, 38.3%,
and 0.9% reporting average levels of their pain as
very mild, mild, moderate, severe, and very severe,
The median VNRS at which the patients
requested analgesics was 6.5, with 38.3%, 59.1%, and
2.6% stating they required analgesics when their
levels of pain were moderate, severe, and very severe,
When asked about their opinions concerning
to what extent their analgesics actually relieved
their pain, 8.7%, 34.8%, 52.2%, and 4.3% rated the
effectiveness as little, moderate, a lot, and maximum,
Around 4/5 (81.7%) reported their sleep was
disturbed by pain, and approximately 2/5 wanted to
receive stronger analgesics (37.4%) or more frequent
Approximately half (58 in 115, 50.4%) indicated
they were markedly satisfied with their postoperative
pain management, while 7%, 36.6%, and 5.4% accounted
their satisfaction as maximum, moderate, and mild,
respectively. The reasons for their satisfaction are
demonstrated in Table 1. One patient (0.9%) indicated
dissatisfaction because he desired a higher dose of

Attitudes of the patients regarding
postoperative pain and its management are shown in
Correlation between expected and experienced pain
Approximately one-third affirmed their levels
of expected and experienced pain were identical. Of
those stating differences, 31.3% and 37.4% had less
and higher pain than their expectations, respectively.
The finding discovered that the participants
preoperatively expected postoperative pain and
actually experienced pain postoperatively. The mean
maximum pain quantified by VNRS was high and
the mean value of average pain was substantial. The
greater part satisfied with postoperative pain relief
in varying degrees. Their attitudes regarding post-
operative pain and management were interesting, as
many had misconceptions.
In the present study, almost all expected and
actually experienced postoperative pain. Expected
pain has been found to have a predictive value for
postoperative pain(20). Their mean value of maximum
pain reached 7.7, which is considered as severe(21).
It is interesting that although their pain levels were
high, the majority did not want to receive stronger
analgesics nor more frequent administrations, a
phenomenon also noted in another study(8).
Only one-third expected and experienced the
same levels of postoperative pain. Among these who
reported a disparity, more than 50% experienced higher
pain than expected. The result is different from another
study performed by Nimmaanrat S et al, in which 71%
of patients who reported differences between expected
and experienced pain had less pain than expected(8).
The present study demonstrated that
though the pain was severe, only one patient was
dissatisfied. The result is in conjunction with previous
studies(2-4,22-25). Satisfaction is multifactorial(26), the
relevance of satisfaction as an optimal outcome
measurement in quality assurance processes might be
“Staff-pleasing-factor”(22) must be taken into
account while interpreting patients’ satisfaction. It is a
factor commonly found in Thais, as they wish to pay
respect and be nice to people who help or take care of
them, but may be less so elsewhere.
The very high proportion agreed that
postoperative pain was something occurring naturally
Believed that postoperative pain was inevitable
Expected postoperative pain would be more severe than what was actually experienced

as a result of surgery, in accordance with previous
studies(1,24). However, with available medical service,
such pain can be adequately controlled. Preoperatively,
advising the patient about postoperative pain
management options was suggested, and that it played
a major role in effective management. Preoperative
information has been shown to assist patients’ active
participation in their care, and thereafter may lead to
It is a master of concern that some patients
agreed that analgesics could not ease pain. Possible
reasons may be related to the patients themselves,
health care workers (negative attitudes, etc.) or the
system of health service (limited resources, etc.).
Education should be a priority for both health care
professionals(28,29) and patients(29).
It is very interesting that many of them agreed
that good patients should avoid complaining about
pain, which is in accordance with a previous study(8). It
is a feature of Thai culture that Thais think that they
should not waste the time of health care professionals
by complaining of their pain. They may feel their health
care professionals should not spend a lot of time on
their personal pain because they will then have less
time for other patients who may be in more need. It has
been found that culture can influence the expression
of pain(30) while ethnicity influenced experimental
pain(31). In chronic pain patients, race has been
found to affect pain reporting, opioid requirements(32)
and coping skills(33). Such attitude was considered
as an area to be addressed for improvement of pain
Some patients agreed that they could get
addicted to analgesics easily, in agreement with a
previous study(34). The duration of acute postoperative
pain is short so it is unlikely to get addicted to
A significant number believed that tolerating
postoperative pain was easier than to tolerate the side
effects of analgesics. It has been well recognized that
every patient has the right to effective postoperative
pain control, as well as to avoid and get relief from
other adverse effects. Multimodal analgesia has been
confirmed to improve the adequacy of postoperative
pain control while minimizing side effects(35).
The strengths of the present study are a
preoperative/postoperative study design, procedure-
specific and a large sample size (more than 100 patients).
It also provides cross-cultural data that could improve
the understanding of perceptions of postoperative
On the other hand, the present study has some
limitations. The studied patients may not represent
the population at large. The majority was male and it
has been clarified that men and women have a different
pain threshold and tolerance(36). Different ethnicities,
races, cultural traditions, types of surgery, varieties of
hospitals and health care services may lead to different
results. Additionally, attitudes, knowledge and
prescribing habits of physicians have also been
shown to affect adequate pain management(37). More
sophisticated and larger scale studies including a
wide variety of patients and health care providers are
suggested to advance the understanding and to help
improve the quality of the health care service.
In conclusion, the present study demonstrated
that the patients expected and truly experienced
postoperative pain following arthroscopic cruciate
ligament reconstruction. Their intensities of pain were
high measured by both the VNRS and VDS, but the
majority of them were satisfied with the pain relief
provided. Many of them held misconceptions toward
postoperative pain and its management. Postoperative
pain management is an area in which there is still
considerable room for improvement, particularly in the
way to deal with the patients’ knowledge, attitudes,
and expectations prior to surgery.
