Background: Being healthcare professionals, the dentists should be aware of the basic and practical aspects of basic life support (BLS) and cardiopulmonary resuscitation (CPR). This study helps assess the knowledge and awareness of dental professionals toward it. Aim: The aim of the study is to assess the level of knowledge, awareness, and attitude toward “BLS” among dental students, interns, and dental practitioners. Materials and Methods: This survey-based study enrolled 70 students from 3rd-year BDS, 70 students from final-year BDS, 80 interns, and 45 dental academicians/practitioners of the dental college. A semi-structured, validated, peer-reviewed questionnaire was used with three sections – demographic data, qualification, and experience; knowledge of participants regarding BLS (26 multiple-choice questions); and awareness and attitude toward BLS (7 close-ended questions). Results: Surprisingly, none of the 265 participants had complete knowledge of BLS and CPR. They lacked in basic knowledge of this important lifesaving protocol. The students and interns also were unaware of basic and applied knowledge of BLS, which shows the necessity of its inclusion in BDS curriculum. Conclusion: The understanding of lack of knowledge and awareness about BLS and CPR is alarming. Its inclusion in curriculum, training, and periodic re-training of dental undergraduates, interns, postgraduates, academicians, and practitioners is necessary.

| Introduction|| |
Ronald Regan once said, “Failing to prepare is preparing to fail.” This philosophy is true during a medical crisis when minutes can be the difference between life and death. When a patient experiences a respiratory arrest, cardiac arrest, or obstructed airway, one needs to act swiftly and promptly starting with basic life support (BLS) skills. Cardiopulmonary resuscitation (CPR) is a simple lifesaving protocol following a life-threatening medical emergency, invented in 1960. It includes psychomotor skills for performing high-quality CPR, using an automated external defibrillator (AED), and relieving an obstructed airway for patients of all ages. Resuscitation is the art of restoring life or consciousness of one apparently dead. BLS is a level of medical care, which is used for patients with life-threatening illness until the patient can be given full medical care. As per the American Heart Association, CPR should start within 10 s of recognition of cardiac arrest. This awareness has placed a growing demand on medical personnel for expertise in resuscitation. BLS requires nothing as far as resources are concerned and its importance is undeniable. Proper practice of the techniques and maneuvers enables a person to effectively resuscitate a victim. Ideally, everyone should know BLS and CPR, and especially for medical personnel, it should be a prerequisite for entering into this field. All medical, nursing, and paramedical students are expected to know resuscitation. The ability to diagnose and treat a respiratory or cardiac arrest is a basic medical skill that all doctors are generally assumed to possess.
The number of such studies carried out in Maharashtra assessing the knowledge, awareness, and attitude of dental practitioners toward BLS is less. It is important that every member of our community should be trained in effective BLS technique to save lives. At least doctors, including dental practitioners, and medical and paramedical staff, should be trained in high-quality CPR, as it is a basic medical skill, which can save many lives if implemented timely. Dentistry is a specialized branch and has made an immense progress. To ensure better and safer healthcare, it is essential for all dental practitioners to be well versed with BLS.
(1) To assess the level of knowledge, awareness, and attitude toward “BLS” among dental students, interns, and dental practitioners. (2) To compare the knowledge score and awareness and attitude of BLS and CPR between students, interns, and practitioners.
| Materials and Methods|| |
This survey-based study enrolled 70 students from 3rd-year BDS, 70 students from final-year BDS, 80 interns, and 45 dental academicians/practitioners of the dental college. A semi-structured, validated, and peer-reviewed questionnaire was used. Cronbach's alpha analysis was done after face validity to check the reliability and validity of the questionnaire. It was composed of three sections which included: (1) demographic data, qualification, and experience; (2) knowledge of participants regarding BLS (26 multiple-choice questions [MCQs]); and (3) awareness and attitude toward BLS (7 close-ended questions). In the first section, the respondents had to provide information regarding gender, age, and academic level and total years of clinical/academic experience. The second section comprised 26 MCQs prepared from guidelines for CPR 2015 by the American Heart Association and Handbook for BLS by American Red Cross. An answer key was also prepared for the same. Finally, in the third section, the information was obtained about training, previous experience in CPR, opinion about inclusion in the curriculum, etc., The volunteers were also given the opportunity to explain the reasons why they would feel reluctant, hesitant, or less confident in such emergency scenario.
Participation in the survey was completely voluntary. The participants were advised to answer the questions without resorting to literary material or other professionals. They needed to answer all the three sections of the questionnaire. To avoid any malpractice while answering the questionnaire, the participants were asked to fill up the details in front of the investigator; hence, it was supervised. Every precaution was taken to protect the privacy of the research subject and the confidentiality of their personal information. The knowledge score for every participant was calculated, where 26 was the maximum score possible and 0 was the minimum score. The more the score, the better is the knowledge regarding BLS. Approval from the institutional ethics committee was obtained before the study.
The data were entered into Microsoft Office Excel, and analysis was done using Statistical Package for the Social Sciences (SPSS) version 16.0, Brand name- IBM SPSS Statistics, License- Trialware/ SasS, Operating system- Windows, macOS, Linux. One-way ANOVA test was used to determine whether there were any statistically significant differences between the means of independent groups. Chi-square test–post hoc test was done to test relationships between categorical variables. The level of significance was taken at a P < 0.05.
| Results|| |
Assessment of knowledge score between four groups and comparison of mean were done by one-way ANOVA. P < 0.001 and the results were significant [Table 1]. The mean score was highest in Group 3 followed by Group 2, Group 1, and Group 4. Subgroup comparison of knowledge scores was done by Benferroni post hoc test [Table 2]. When Group 1 was compared with other groups, the difference was significant with Group 3. When Group 2 was compared with other groups, the difference was significant with Group 4. Similarly, the results of Group 3 were significant with Group 1 and 4 and that of Group 4 with Group 2 and Group 3. All questions were also individually assessed to test the exact areas of presence of knowledge and lack of knowledge. Kruskal–Wallis ANOVA test was done for intragroup comparison while Mann–Whitney test was done for intergroup comparison.

Out of all 26, few most important questions are discussed here. To our surprise, only 17.7% of 3rd-year students, 15.9% of final-year students, 15.8% of practitioners, and 30.3% of interns knew the correct order of performing CPR. Mean score was calculated [[Graph 1] - Question 4]. Rate of chest compression in adults and children during CPR was known by only 27.2% of 3rd-year students, 22.1% of final-year students, 20.3% of practitioners, and 30.6% of interns. Mean score was calculated [[Graph 2] - Question 16]. 25.7% of 3rd-year students, 26.8% of final-year students, 26.9% of practitioners, and 26.4% of interns could tell correct technique to maintain airway in victims. Mean score was calculated [[Graph 3] - Question 7]. 27.5% of 3rd-year students, 26.1% of final-year students, 28.6% of practitioners, and 25.4% of interns knew correct compression–ventilation ratio in adults. Mean score was calculated [[Graph 4] - Question 17]. The questions based on clinical judgment and experience were well answered by practitioners as compared to other groups. Mean score was calculated [[Graph 5] - Question 5 and [Graph 6] - Question 24].
Attitude and awareness of all participants was assessed too. 99.1% of the participants felt that it is necessary for dentists and dental auxiliary to have adequate knowledge of BLS and CPR. Only 13.6% of them had previously attended the workshop or lectures related to BLS and CPR. Out of them, many participants had attended it within the last 5 years. 84.1% of them had never performed CPR nor had seen administering it. If a situation demands, 78.1% of the participants would not feel confident in administering CPR; the common reasons being inadequate theoretical knowledge, inadequate or no training offered in UG/PG curriculum, nonupdated knowledge, fear of causing more harm to patient, and general lack of interest. 99.1% of them felt the necessity of inclusion of BLS in the UG and PG curricula.
| Discussion|| |
A study by Müller et al. found that medical emergencies are common in dental practice, as about two-third ofthhe dentists faced at least one emergency during the 12-month study period. The combined findings of surveys by Fast et al. and Malamed, showed 30,602 emergencies occurring over a 10-year period in the offices of the 4309 dentists reporting. The gravity of these situations justifies the need for every dental practitioner to be at least able to perform the basics of CPR: chest compression and rescue breath. Indeed, during a cardiac arrest, in the absence of CPR, the chances of survival are reduced by 7%–10% every minute after the event begins. Hence, in the United States, BLS training has been recommended for all healthcare professionals since 1966. Different reports have described the knowledge of BLS among dentists in India, but a little research regarding this has been carried out in Maharashtra. Chandrasekaran et al. evaluated the knowledge of BLS among healthcare students and professionals in Tamil Nadu and found that the study participants were severely lacking in BLS knowledge. Another study by Reddy et al. concluded poor knowledge regarding BLS among dental students in dental school of India. A study by Gonzaga et al. found that 86% of the interviewed dentists had received information about CPR; however, most of them had not received practical training for it. Another study by Raghava and Attar Nazir showed poor knowledge of BLS among dental interns in dental college of Mangalore.
The basic knowledge of practitioners tends to fade over the years due to lack of periodic training and retraining. Interns tend to answer the basic questions better as they tend to attend related lectures or workshops. Overall, the knowledge of dental students, faculty, and practitioners remains poor regarding very important lifesaving protocols.
| Conclusion|| |
The understanding of lack of knowledge and awareness of dentists about BLS and CPR is alarming. As they belong to the category of healthcare professionals, training and periodic re-training of dental UGs, interns, PGs, academicians, and practitioners for BLS measures, CPR and management of medical emergencies is necessary. In addition, its inclusion in the UG curriculum is extremely essential.
Drawbacks of the study were that practical skills could not be assessed. The survey can also be repeated once BLS and CPR workshop is taken to assess improvement in the knowledge of participants.
