Physicians' attitudes and knowledge concerning antibiotic prescription and resistance: questionnaire development and reliability.

ABSTRACT: Understanding physicians' antibiotic-prescribing behaviour is fundamental when it comes to improving antibiotic use and tackling the growing rates of antimicrobial resistance. The aim of the study was to develop and validate--in terms of face validity, content validity and reliability--an instrument designed to assess the attitudes and knowledge underlying physician antibiotic prescribing.The questionnaire development and validation process comprised two different steps, namely: (1) content and face validation, which included a literature review and validation both by physicians and by Portuguese language and clinical psychology experts; and (2) reliability analysis, using the test-retest method, to assess the questionnaire's internal consistency (Cronbach's alpha) and reproducibility (intraclass correlation coefficient--ICC). The questionnaire includes 17 items assessing attitudes and knowledge about antibiotic prescribing and resistances and 9 items evaluating the importance of different sources of knowledge. The study was conducted in the catchment area covered by Portugal's Northern Regional Health Administration and used a convenience sample of 61 primary-care and 50 hospital-care physicians.Response rate was 64% (49% to retest) for primary-care physicians and 66% (60% to retest) for hospital-care physicians. Content validity resulted in 9 changes to professional concepts. Face validity assessment resulted in 19 changes to linguistic and interpretative terms. In the case of the reliability analysis, the ICC values indicated a minimum of fair to good reproducibility (ICC > 0.4), and the Cronbach alpha values were satisfactory (α > 0.70).The questionnaire developed is valid--in terms of face validity, content validity and reliability--for assessing physicians' attitudes to and knowledge of antibiotic prescribing and resistance, in both hospital and primary-care settings, and could be a very useful tool for characterising physicians' antibiotic-prescribing behaviour.

Project description:BackgroundUpper Respiratory Infections (URIs) are common in children. The cause is usually viral, but parents' attitude often contributes to inappropriate antibiotic prescribing, promoting antibiotic resistance. The objective is to describe the process of developing a questionnaire to assess parents' Knowledge, Attitude and Practices (KAP) concerning the role of antibiotics when children suffer from URIs, as well as to evaluate the response rates, the completeness and the reliability (Cronbach) of the questionnaires. Finally, to note any limitations of the study.MethodsLiterature review, along with pre-testing yielded a questionnaire designed to assess the parents' KAP-level. A postal survey was set, in a national sample of 200 schools stratified by geographical region. The participants consist of a multistage geographical cluster sample of 8000 parents. The influence of demographic characteristics (i.e. sex, age, education) was analyzed. Cronbach index test and factor analysis were used to assess the reliability of the questionnaire.ResultsThe response rate of the parents was 69%. Islands presented the lowest response rate while in Northern Greece the response rate was the highest. Sixty-eight point nine percent of the sample returned questionnaires fully completed, while 91.5% completed 95% of the questions. Three questions out of 70 were answered in a very low rate which was associated mostly with immigrant respondents. The section describing parents' attitude toward antibiotic use was not completed as much as the sections of knowledge or practices. The questions were factor analyzed and 10 out of the 21 extracted factors were finally evaluated, reducing the number of independent variables to 46. The reliability of the questionnaire was 0.55. However, only items that increased the Cronbach when added were eventually included in the final scales raising the internal consistency to 0.68. Limitations of the study, such as the vocabulary and form of the questionnaire and the idiocycrancy of the respondents, emerged during the analysis.ConclusionThe response rate and the completeness of the questionnaires were higher than expected, probably attributed to the involvement of the teachers. The study findings were satisfactory regarding the development of a reliable instrument capable to measure parents' KAP characteristics.

Project description:BackgroundOver the past five decades, palliative care has changed from helping patients at the end of life into a highly dedicated service focused on delivering supportive care to patients with life-limiting illnesses throughout the disease trajectory. To date there is no common agreement on universally applicable measurement tool to know the areas of weakness in physicians' understanding of palliative care and identifying misconceptions about palliative care. This paper describes the development of a reliable and valid questionnaire to provide a measure of the attitude and knowledge of physicians toward palliative care (PCAK).MethodsItem pool was generated paying particular attention to content and face validity. The initial version of the questionnaire was piloted and assessed based on psychometric criteria. Items which did not reach acceptable validity were excluded, and the final 37 item version was administered to two groups differing in their palliative care attitude and knowledge on two occasions to assess the construct validity and test-retest reliability. Two hundred thirty two physicians working in primary care clinics and general hospitals completed the questionnaire at the piloting stage. The final version (PCAK) was administered to 35 oncologists and 76 physicians. SPSS v20 was used for statistical analysis.ResultsOf the Pilot study, 20 items were excluded because didn't meet the criteria for item difficulty and discrimination. Item-to-total-score correlations (r) was ranging from 0.347 up to 0.806. Internal consistency (Cronbach's alpha) was high ranging from 0.636 to 0.824. While testing the final PCAK, oncologist scored consistently higher than the other physicians on all sections of the questionnaire (P < 0.001) suggesting good construct validity. Test to retest reliability for each section was very high, ranging from 0.879 to 0.97 and the overall reliability was 0.95. The internal consistency reliability of each section was very good ranging from 0.681 ± 0.893.ConclusionThe findings demonstrate that PCAK meets psychometric criteria for reliability and construct validity. It provides a useful scale to assess the attitude and knowledge of physicians about palliative care helping in planning of educational programs for physicians.

Project description:BackgroundAntibiotic resistance has been identified as a global health threat. Knowledge, attitudes, and inappropriate prescription practices of antibiotics by physicians play a crucial role in this problem. In Colombia, research addressing this issue is scarce.MethodsA cross-sectional study involving 258 physicians was conducted. A scale with questions on sociodemographic aspects, level of education, satisfaction with antibiotic education received, and knowledge, attitudes, and practices was administered. The scale was designed for each item to be analyzed individually or as a total score ranging from 0 to 100 (0 being the lowest and 100 the highest).Results31.5% of physicians rated the education received on antibiotics as fair to poor. The knowledge score was 80.1 (IQR 70.5-87.5); however, 25.2% agreed to some extent that amoxicillin is useful in treating most respiratory infections, and 15% agreed that antibiotics are effective in treating upper respiratory infections. Attitudes scored 80.2 (IQR 75.0-86.5), with 99% stating that bacterial resistance is a public health problem in Colombia, but only 56.9% considering it a problem affecting their daily practice. Practices scored 75.5 (IQR 68.8-81.2), and 71.7% affirmed that if they refuse to prescribe antibiotics to a patient who does not need them, the patient can easily obtain them from another physician. General practitioners were found to have lower scores in all three indices evaluated.ConclusionThe study reveals enduring misconceptions and concerning practices in antibiotic prescription, particularly among general practitioners. Enhancing knowledge necessitates the implementation of continuous medical education programs that focus on updated antibiotic guidelines, and resistance patterns. Fostering positive attitudes requires a culture of trust and collaboration among healthcare professionals. Practical enhancements can be realized through the establishment of evidence-based prescribing guidelines and the integration of regular feedback mechanisms. Moreover, advocating for the inclusion of antimicrobial stewardship principles in medical curricula is crucial, emphasizing the significance of responsible antibiotic use early in medical education.
