Abstract

Cardiopulmonary resuscitation (CPR) is an emergency procedure that combines chest compressions often with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. The families of those who survive a heart attack or have a history of heart problems should also take CPR training. Chance of survival increases four-fold with immediate action. Hence, a quasi experimental research was conducted to assess the effect of cardiopulmonary resuscitation demonstration on knowledge, attitude and practice among relatives of cardiac patients of tertiary care hospital, south India. Totally 30 subjects who fulfilled the criteria were chosen by convenient sampling technique. Conceptual framework comprised of Ludwing Bertalanffy's General System Theory. Semi structured interview questionnaire was utilized to assess the knowledge. Attitude was assessed through the scale and the practice was measured using the checklist. Subjects were tested both before and after cardiopulmonary resuscitation demonstration. The mean difference of knowledge was 9.73, with combined SD of 5.51 and‘t' value of 15.35. Paired‘t' test showed that there was a significant difference in pre-test and post-test level of knowledge at 0.05 level. The calculated attitude‘t' value (5.56) and practice‘t' value (85.57) were higher than table values. The study findings highlighted the advantages of having demonstration in improving knowledge, attitude and practice of cardiopulmonary resuscitation among relatives of cardiac patients.

Introduction

Human heart beats about 1,00,000 times a day, 70-80 times a minute, surges 2000 gallons of blood through 60,000 miles of blood vessels which feeds the body organs and tissues. Heart receives its blood supply from the right and left coronary arteries which originates from aorta [1].

Any damage to the coronary artery reduces the pumping power of heart. When the heart fails to contract effectively; cardiac arrest occurs. Arrested blood circulation prevents delivery of oxygen to the body. Lack of oxygen to the brain causes loss of consciousness, which results in abnormal or absent breathing. Cardiac arrest if untreated can damage brain or can lead to a sudden death [2].

Cardiopulmonary resuscitation is a lifesaving technique useful in many emergencies, including heart attack or near drowning. It consists of the use of chest compressions and artificial ventilation to maintain circulatory flow and oxygenation during cardiac arrest [3]. Although survival rates and neurologic outcomes are poor for patients with cardiac arrest, appropriate resuscitation involving early defibrillation and proper implementation of post cardiac arrest care lead to improved survival and neurologic outcomes.

Indians are far behind in the global surge to learn cardiopulmonary resuscitation. The World Heart Federation reports that less than 1% Indians would presently know how to carry out a cardiopulmonary resuscitation. Being trained to perform cardiopulmonary resuscitation can make the difference between life and death [4]. The proffered way to learn cardiopulmonary resuscitation is to practice cardiopulmonary resuscitation. Therefore the present study was conducted with the following objectives:

  • To assess the level of knowledge, attitude and practice regarding cardiopulmonary resuscitation among relatives of cardiac patients.
  • To assess the effectiveness of cardiopulmonary resuscitation demonstration among relatives of cardiac patients.
  • To determine the association between knowledge, attitude and practice with selected demographic variables.

Methods

Study Sample and setting

A quasi experimental research design was adopted. Ludwing Bertalanffy's General system theory was adopted for conceptual framework. Quasi pre experimental one group pretest posttest design was selected for this study. Eligibility criteria included relatives of cardiac patients waited in cardiac wards, were willing to re-demonstrate cardiopulmonary resuscitation procedure and understood Tamil or English were included in the study. Relatives who were not competent to perform CPR and may not be with patient on an emergency were excluded from sampling. Ethical protocols and hospital's policy on protection of patients' rights, privacy and confidentiality were assured firmly. The authors provided patient and their relatives with oral and written clarifications about the purpose of the study and its procedures and asked for their willingness to participate in the study. After obtaining patients and relatives' consent, Tamil versions of knowledge questionnaire, attitude scale and practice checklist were administered to each participant during a face-to-face interview. The English version of the used tools was forward and backward translated into Tamil by independent expert and underwent pilot testing with representative homogenous sample. After completing data collected packages were kept safely to guarantee confidentiality and anonymity.

Tools

Knowledge questionnaire

The knowledge items had 20 questions. The correct answer was scored as ‘1' and the wrong answer as ‘0'.the scores were interpreted as 0-6: Poor knowledge, 7-13: Fair knowledge, 14-20: Good knowledge.

Attitude scale

Attitude scale had ten statements, with five positive and five negative scores. The scores <50% were considered as unfavourable, 50-75%: moderate and >75% was scored as favourable.

Practice checklist

Practice checklist had 15 steps.Score ‘1' was given for each right performance. ‘0' score was given if the steps went wrong. The ranges were interpreted as<4 score, poor performance, 4-7 moderate, 8-11 good and 11-15 for excellent performance.

Data Analysis

Data analyses were conducted using the IBM SPSS 20.0. Descriptive statistics were used to describe the demographics of the sample. Mean and standard deviations were used to describe the distributions of knowledge, attitude and practice on CPR. Paired “t” test was used to compare the pre and post test results.

Results

Subject Characteristics

A total of 30 relatives of patients waited near intensive coronary care unit and in cardiology ward were approached to participate in the study [9,10]. Most of the participants belonged to the non medical profession (97%). Majority had previous knowledge of CPR (83%) and almost everyone had never seen cardiopulmonary resuscitation procedure (97%).

In pre-test majority samples (53%) had fair knowledge whereas in post test most (90%) of the study participants had good knowledge [10]. Similarly in pre-test majority (57%) had moderate and (53%) had favourable attitude towards CPR in post-test.

All participants (100%) had poor practices when pretested. This figured (97%) excellence after intervention, with the mean score 13.7 and a SD of 0.86.



Reliability assessment

The reliability of the tool was determined by the Spearman Brown's Split-Half technique showing r=0.89 for knowledge questionnaire, r=0.99 for attitude scale and r=0.98 for practice checklist. Hence the tool was found highly reliable.

Validity assessment

The content validity of the instrument was ensured based on opinion from experts.

Discussion

Present study findings were consistent with Rajpakse (2010) [5] who assessed the knowledge of public regarding cardiopulmonary resuscitation. Telephonic survey regarding knowledge on cardiopulmonary resuscitation revealed that trained people had better knowledge on cardiopulmonary resuscitation than untrained people even though both of them had low knowledge levels.

Also current study correlates the evidence by Reder S (2006) [6] who reported that hands on training on cardiopulmonary resuscitation were effective in improving knowledge and performance of cardiopulmonary resuscitation among school students [7].

The mean difference of attitude was 10.1, with the combined SD of 11.38, hence found significant difference in pre-test and post-test attitude scores [8]. Similarly the mean difference of practice scores was 13.7, with the combined SD of 0.86, and found significance difference in post-test.

Hypotheses were verified and gave rise to positive correlations.

Conclusion

Thus the study concluded that, demonstration on cardiopulmonary resuscitation was an eminent and effective method to improve knowledge, attitude and practice regarding cardiopulmonary resuscitation. Demonstration on cardiopulmonary resuscitation can be introduced as a routine program for relatives of cardiac patients in clinical areas. Nursing research on cardiopulmonary resuscitation would be a valuable reference material for further researchers.
