Abstract

Introduction

Following great progress and advances in the field of anesthesia, anesthesiologists now play key roles in the intensive care unit, on the code team, and in the pain clinic, as well as in the operating room. However, there is little public exposure regarding the role of anesthesiologists in the various areas of hospitals. Furthermore, patients' awareness of the roles of anesthesiologists even in the operating room is limited, as proven by several worldwide studies [1-8].

Recently in Korea, the Korean Society of Anesthesiologists (KSA) has attempted to inform the public of the role and importance of anesthesiologists. Additionally, the KSA planned the first national public survey to investigate general knowledge of this topic. This off-line survey was conducted by a professional research organization to obtain exact and reliable data.

The aims of this survey were to determine the views of Koreans on the specialty of anesthesiology and the role of anesthesiologists and to explore the ways in which individual anesthesiologists and the KSA inform the public. This study also evaluated the difference in awareness between people who had undergone surgery under anesthesia and those who had not experienced surgery.

Materials and Methods

The survey was designed by the Korean Society of Anesthesiologists (KSA), to determine the national public's awareness of the specialty of anesthesiology and the role of anesthesiologists. The questionnaire was generated from a review of the literature on a similar topic [1-10] and modified according to local perceptions in the country. The questionnaire collected data on participant characteristics (age, gender, education level, occupation, and history of previous anesthesia exposure) and on perceptions of the specialty of anesthesiology and the role of anesthesiologists inside and outside the operating room. It also explored participants' desire for explanation of anesthesia by anesthesiologists and their opinion about how to raise awareness about anesthesia and anesthesiologists.

The survey was administered to 1000 members of the general public who had no specific ties to anesthesia or surgery and who were selected proportionally from each province according to the national population. This off-line national survey was conducted by a professional research organization in Korea, the Marketing Research Korea Co., Seoul, Korea.

All analyses were performed using SPSS software (ver. 12; SPSS, Chicago, IL, USA), and statistical significance was set at P < 0.05. Statistical analyses were performed using Pearson's chi-squared test or Fisher's exact test.

Results

Of the 1000 survey participants, 499 (49.9%) reported that they had had previous anesthetic surgical experience (Group Y), and 501 (50.1%) reported no such prior experience (Group N). In group Y, 210 (42%), 105 (21%), 44 (9%), and 85 (17%) participants answered that they had received general anesthesia, spinal anesthesia, ambulatory sedative anesthesia, and other types, respectively. Fifty-five participants (11%) answered "I don't know."

Table 1 summarizes the demographic data of the two groups. Table 2, 3, and 4 show the results of the questionnaire about the public's awareness regarding the preoperative, intraoperative, and postoperative specific roles of those involved in surgery with anesthesia, repectively. Table 5 shows the results to the question about the roles of doctors specialized in anesthesia (i.e., anesthesiologists) in the hospital (multiple choices). Table 6 shows the results of the public's request for information about anesthesia given by an anesthesiologist. Finally, Table 7 shows the public's perception of mass media presentations of the role of a doctor specialized in anesthesia during surgery, and their opinions on the best way to raise awareness about doctors specializing in anesthesia (multiple choice).

Discussion

To our knowledge, this is the first national survey exploring general public awareness about the specialty of anesthesiology and the role of anesthesiologists. Although several surveys of this nature have been performed worldwide, most were performed in only one or a few hospitals [1-10], representing only patients' awareness in a limited area. In contrast, the results of our nationwide survey more accurately indicate general awareness. Furthermore, all previous surveys included patients awaiting elective surgery [1-10], with the result that the participants may have had an increased interest in anesthesia or surgery. However, the present survey targeted members of the general public who were not linked with anesthesia and were not awaiting surgery, likely yielding more objective results.

In the present study, 25.2% of respondents did not know that a doctor specialized in anesthesia who is the Korean expression for an anesthesiologists is in charge of anesthesia for surgery. Moreover, according to the detailed results, even respondents who knew that had very little knowledge of the actual roles and responsibilities of this doctor during anesthesia, and this level of knowledge was lower than that found by other surveys [1-10]. Regarding to the preoperative role of anesthesiologists, 86.5% and 70.8% of those surveyed thought that the surgeon decides the operability and NPO time, respectively. During surgery, 46.2% of them answered that the surgeon is in charge of monitoring vital signs, despite the fact that this is actually one of most important roles of anesthesiologists. Strikingly, even the nurse was more likely to be selected as responsible for this role (33.3%), and only 18.8% of people chose the anesthesiologist, considerably lower than in other surveys [1-10]. They also thought that estimation of blood loss and administration of transfusions were performed by the surgeon (65.1% and 45.5%), followed by the nurse (24.3% and 42.7%). Only 8.2% and 9.5% of people chose the anesthesiologist for these roles. Also, the majority of participants (91.6%) believed that the surgeon performed resuscitation during surgery. Although many of those surveyed believed that the anesthesiologist performed anesthesia for surgery, most of them seemed to have very little understanding of the province of anesthesia itself. Regarding the roles outside the operating room, 6-28.7% of those surveyed were aware of anesthesiologists' other roles outside the operating room. On the other hand, 50.1% thought that the anesthesiologist performed local anesthesia for a simple surgery in the OPD, indicating that the public has little understanding of the actual roles of an anesthesiologist.

In this survey, interestingly, those with prior anesthetic experience were more likely to believe that the surgeon takes responsibility for some intraoperative management and that nurses are in charge of recovery from anesthesia and managing the postoperative pain than were those who had no such prior experience. These results may be due to the fact that the surgeons explain the surgery for the patients before the operation and visit them postoperatively, leading them to believe that the surgeon plays a key role in most areas of surgery, including anesthesia. Moreover, most patients directly contact the nurses if any problems arise in the immediate recovery. In contrast, most anesthesiologists visit the patients only one time preoperatively, although some studies have discussed that patient orientation in the pre-anesthetic visit is a way of publicizing the image of the professional and achieving patient recognition [2,8,11]. In this survey, 91% of respondents indicated a desire for information about their anesthesia from an anesthesiologist. Dedicated personal care including postoperative visits has been shown to be one of the most important factors affecting perception of the anesthesiologist. One study reported that perception of the anesthesiologist and satisfaction were significantly increased by a single postoperative visit by the anesthesiologist [12].

Our results showed that 38.7% of those surveyed experienced the roles of anesthesiologists via the mass media, and the results were similarly ordered in both groups (television > internet > informational brochure). Those surveyed differed in their opinion about the best way to raise awareness about anesthesia and the anesthesiologist depending in part on whether they had prior experience with anesthesia. The experienced public chose television program > information brochure > internet, but none of the experienced public chose television program > internet > information brochure. This difference may reflect the effects of information about anesthesia and the anesthesiologist given by brochure during admission for surgery. Recently, the KSA produced a simple but informative cartoon brochure that was distributed to hospitals nationwide, and both the patients' and anesthesiologists' response was very positive. Considering that the most frequent source of media awareness about anesthesiologists is television program, the public seems to prefer to be informed by methods already present in their daily lives. To provide information most effectively, the National Society of Anesthesiology of each country should consider its publics' thoughts and preferences, and periodic surveys every 5-10 years may be helpful to gather feedback from the public on this topic.

In conclusion, the Korean public has inadequate knowledge regarding the specialty of anesthesiology and the role of anesthesiologists inside and outside the operating room. To improve this awareness, in hospitals, each anesthesiologist should provide patients with more exact and detailed information and explain their anesthetic protocol by a postoperative visit as well as a preanesthetic visit. Simultaneously, the National Society of Anesthesiology should provide systematic information reflecting the public's thoughts and preferences.
