Abstract
The study was conducted to evaluate the correlation between the knowledge and practices of radiologic technologists in performing quality assurance in general radiography. Furthermore, the association of the demographic variables such as age, sex and length of service on knowledge and practices in performing quality assurance in general radiography was determined.
Methodology
This study utilized a correlational research design which was used to establish the association between the knowledge and practices of radiologic technologists in performing quality assurance in general radiography. The researchers used a self-made questionnaire which was divided into three parts: the first part included the demographic variables of the respondents. The second part was composed of 20 questions regarding the knowledge of the respondents. The last part consisted of 20 questions which determined the practices of the respondents. The data were analyzed using statistical treatments such as mean, frequency, standard deviation, percentage, t-test for independent means, analysis of variance, and Spearman's rank correlation.
Findings of the study
Based on the gathered data, the following were the findings of the study:
1. Out of the 83 respondents, majority belong to ages 20 to 29 years old (83%), are males (57 %) and have been in service for 5 years and below (81%).
2. Respondents have a very high knowledge in performing quality assurance in general radiography (M = 18.87, SD = 1.83).
3. Provisions in performing quality assurance in radiography was practiced to a great extent (M = 4.07, SD = 0.69) by the respondents.
4. There are no significant differences on the knowledge of the respondents in performing quality assurance in general radiography when grouped according to age, F (2, 80) = 1.684, p = 0.192; sex, t (81) = -1.901, p = 0.061; and length of service, F (3, 79) = 0.691, p = 0.560. The null hypotheses are not rejected.
5. There are no significant differences on the practices of the respondents in performing quality assurance in general radiography when grouped according to age, F (2, 80) = 2.354, p = 0.102; sex, t (81) = -1.979, p = 0.051; and length of service, F (3, 79) = 0.289, p = 0.833. The null hypotheses are not rejected.
6. There is a low positive significant correlation between the respondents’ knowledge and practices in performing quality assurance in general radiography, r (81) = 0.369 p = 0.001. The null hypothesis is rejected.
Conclusions
Based on the findings of the study, the following conclusions were drawn:
1. Majority of the respondents are male, belonged to age group of 20-29 years old, and have a length of service for 5 years and below.
2. The respondents have a very high knowledge in performing quality assurance in general radiography. Aspects of quality assurance particularly in visual inspection of x-ray equipment accessories showed that all of the respondents are knowledgeable while only few of the respondents are knowledgeable about dose monitoring to patients.
3. The respondents practiced the provisions of quality assurance in general radiography to a great extent. Aspects of quality assurance particularly in radiation protection and choosing the appropriate standard medical exposure are being practiced to a very great extent by the respondents. On the contrary, respondents practiced monitoring doses of the patient only to moderate extent.
4. The knowledge of the respondents in performing quality assurance in general radiography do not significantly vary in terms of their sex, age and length of service.
5. The practices of the respondents in performing quality assurance in general radiography do not significantly vary in terms of their sex, age and length of service.
6. There is a low positive significant correlation between the knowledge and practices of radiologic technologists in performing quality assurance in general radiography.
Recommendations
Based on the conclusions of the study, researchers recommended the following:
1. Diagnostic reference levels or DRL have already proved useful as a tool in support of dose monitoring in promoting improvements in patient protection, therefore researchers recommend that DRL should be well established for examinations or procedures carried out in the local area, country or region where they are applied.
2. Further studies examining other variables aside from knowledge and practices are recommended. This is to determine what other factors might have a high positive correlation or relationship with regards to performing quality assurance in the general radiography section.
3. Further studies examining other demographic variables aside from age, sex, and ength of service are recommended. This is to determine what other factors influence the knowledge and practice of radiologic technologists in performing quality assurance.
4. Radiologic technologists must engage in continuing education and training programs in quality assurance as it will be helpful for proper implementation of QA and it would improve knowledge retention and skills alignment.
