Surveying knowledge, practice and attitudes towards intervention fidelity within trials of complex healthcare interventions.

ABSTRACT:

Background

Intervention fidelity is the degree to which interventions have been implemented as intended by their developers. Assessing fidelity is crucial for accurate interpretation of intervention effectiveness, but fidelity is often poorly addressed within trials of complex healthcare interventions. The reasons for this are unclear, and information on the use of methods to enhance and assess fidelity in trials of complex interventions remains insufficient. This study aimed to explore the knowledge, practice and attitudes towards intervention fidelity amongst researchers, triallists and healthcare professionals involved with the design and conduct of trials of complex healthcare interventions.

Methods

An online survey consisting of closed and open-ended questions exploring four sections (Demographics, Fidelity knowledge, Practice and Attitudes) was conducted. This was an opportunistic sample of individuals with experience of direct involvement in trials of complex healthcare interventions (e.g. design/development, conduct, evaluation).

Results

Data from 264 participants representing 15 countries were analysed. The majority (65.9%, n?=?174) of participants identified themselves as 'Researchers'. The majority of participants were familiar with the term "intervention fidelity" (69.7%, n?=?184) and indicated that fidelity is important (89.7%, n?=?236). Mean self-reported understanding of fidelity was moderate. Although 68% (n?=?182) had previously used strategies to assess (e.g. audio/video-recording sessions) and enhance (e.g. training manual) fidelity in trials of complex interventions, only a limited proportion of participants indicated always reporting these strategies in subsequent publications (30.9%, n?=?56). Poor knowledge or understanding was the most commonly cited barrier to addressing intervention fidelity in trials (77.4%, n?=?202). Over half of respondents (52.1%, n?=?137) had never completed specific fidelity training or research, and the vast majority (89.7%, n?=?236) would welcome specific training in this area.

Conclusion

Despite good awareness of intervention fidelity and its importance, poor knowledge and understanding appears to be a key factor limiting how intervention fidelity is addressed in trials of complex interventions. Participants identified a need for further training and education in this area. Additionally, clarification of the terminology, definition and components of intervention fidelity would facilitate better understanding of the concept. A discrepancy between participants' use of fidelity strategies and subsequent reporting raises concerns around inadequate fidelity reporting in the trials literature.

Project description:BACKGROUND:Pakistan has one of the highest reported incidence of vitamin D deficiency in studies conducted worldwide. However, there has been very limited exploration of vitamin D related knowledge, attitudes and practices among healthy youth in Pakistan. METHODS:A cross-sectional survey was conducted among youth (aged >?16?years) from two engineering universities in Pakistan. Participants were asked questions on their concern about vitamin D levels, testing, and supplementation practices. Knowledge was examined using questions about food sources, health benefits and factors affecting vitamin D production within the human body. Of the 900 eligible students invited to participate, 505 (56%) completed the questionnaire and were included in the analysis. RESULTS:Only 9% participants were able to identify the correct food sources of vitamin D, 33% were aware of the bone health benefits (bone health and calcium absorption) of vitamin D and 36% identified sunlight exposure as a factor influencing vitamin D production. Knowledge about food sources and health benefits of vitamin D was not associated with gender and individuals concern about their levels. Those tested and taking supplements were more likely to identify bone related health benefits and factors affecting vitamin D production. Forty percent male and 52% female students expressed concern that their vitamin D levels were too low. However, 72% participants reported that they had never been tested for vitamin D levels. Use of supplements was significantly higher among female students (F?=?52% vs M?=?37%; P?=?0.003). Those who had been tested for vitamin D deficiency were more likely to take supplements. CONCLUSION:Despite being identified as a high-risk population, knowledge about vitamin D was limited among university students. Interventions are needed to increase awareness about the importance of vitamin D for health, including the need for exposure to sunlight and adequate dietary intake of vitamin D. Our study provides much needed baseline evidence for making health-policy recommendations for this vulnerable population group.

Project description:BackgroundSevere acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection is a global pandemic. Healthcare workers' (HCWs) role in patient management is predisposing and can serve as means of hospitals and community transmission. This study evaluated HCWs' knowledge, attitude, and practice towards COVID-19 in Nigeria.Methodswe carried out a cross-sectional survey among HCWs during the COVID-19 outbreak in Nigeria from March to June 2020. The study assessed 346 HCWs for Knowledge, attitude, and practice by using an online (Google form) self-administered questionnaire, based on a convinience sampling technique Data were retrieved and analyzed using descriptive statistics. Chi-Square and one-way ANOVA were used to measure association and difference among demographic variables. The relationship between knowledge, attitude, and practice was measured using Spearman's rho correlation test.Resultsthe mean knowledge score of the HCWs was 7.1 on a scale of 0-8. The correct overall rate of the knowledge questionnaire was 88.75%. Knowledge was gained mainly from television (35.0%) and social media (35.0%). The mean attitude score on a scale of 0-6 was 5.31 ± 0.39. Most (92.5%) participants were confident that Nigerian medical scientists would win the war against COVID-19. The majority (92.2%) of the respondents thought that SARS-CoV-2 was not a biological weapon. About 1 out of 5 respondents held that faith healing or prayer is the only cure for COVID-19. A vast majority of the HCWs were taking precautionary measures such as avoiding crowded places (94.2%), washing of hands (96.0%), and the use of personal protective equipment (91.6%) against SARS-CoV-2 infection. Nevertheless, only 3 out of 5 HCWs used a face mask when leaving home. There was a significant (p = 0.046) positive correlation (0.584) between knowledge and attitude.Conclusionour results showed that HCWs in Nigeria had excellent knowledge and possessed a positive attitude and good practice towards COVID-19. However; there were areas where poor knowledge, negative attitudes and unacceptable practices were observed. We recommend continuous public health education of HCWs on SARS-COV-2 infection control and prevention.

Project description:BackgroundThe prevalence of CAM use is increasing. This integrative review investigated New Zealand healthcare professionals' practice of, attitudes toward, and knowledge about complementary and alternative medicine (CAM).MethodsLiterature search was conducted in four databases from inception to April 2020. Studies were included if they reported results from primary data collection on practice of, attitudes toward, or knowledge about CAM amongst New Zealand healthcare professionals.ResultsEleven studies (two of 'high-quality', seven of 'moderate-quality', and two of 'low-quality') were identified with 2060 healthcare professionals including general practitioners (GPs), nurses, midwives, pharmacists, physiotherapists, and medical specialists. New Zealand healthcare professionals were generally positive regarding CAM use, but have concerns on the scientific evidence, regulation, safety, financial costs of CAM, and encourage an evidence-based CAM practice and stronger CAM regulation. Findings indicated that around 25% of GPs practise CAM, and 82.3% refer patients to CAM practitioners. When treating pregnant women, 48.4% of physiotherapists practise acupuncture, and 37.3% of midwives recommend CAM. GPs believe that acupuncture is the most helpful CAM modality, and most commonly practiced and referred patients to acupuncture. Up to 58% of GPs and Plunket nurses wanted to receive further education on CAM, and up to 66.7% GPs favour the idea CAM should be included in medical curriculums.ConclusionsNine of the 11 included studies were of moderate to high quality, thus enhancing the reliability of the review findings. In order to better manage CAM in New Zealand New Zealand clinical settings, there is a need to invest in CAM research and education, and enhance CAM regulation. This review is a first step in developing an evidence base to offer insights for further development of effective CAM policies regarding safety, efficacy, regulation and integration in New Zealand.

Project description:Aims and objectivesTo evaluate the knowledge and attitudes towards sexual and gender minority (SGM) oncology patients' needs among advanced practice providers (APPs).BackgroundSGM individuals experience health disparities, in part due to lack of access to knowledgeable providers. Despite the important role of APPs in cancer care, less is known about their attitudes and knowledge towards SGM cancer patients.DesignCross-sectional study.MethodsA survey of APPs at a National Cancer Institute-Designated Comprehensive Cancer Center assessed self-reported demographics, attitudes, knowledge and postsurvey confidence in knowledge of SGM oncology patient needs. Reporting of this study adheres to STROBE guidelines.ResultsKnowledge of health needs was low with an average of 2.56 (SD = 1.27) items answered correctly out of 6. The majority of APPs self-reported being comfortable treating SGM patients (93.6% and 87.2%, respectively), but less confident in knowledge of their health needs (68.0% and 53.8%, respectively). Although less than half of APPs believed education should be mandatory (44.9%), 79.5% were interested in education about SGMs' unique health needs. Political affiliation, medical specialty, licensure, and having SGM friends or family were associated with various attitude items, but not knowledge. Moderation analyses indicated that APPs who had greater overall knowledge scores were more likely to agree, on average, that knowing sexual orientation, gender identity and sex assigned at birth are important to providing quality oncology care.ConclusionAPPs report being comfortable providing care for SGMs with cancer, but knowledge gaps remain that may inhibit the quality of care provided. Given the interest in education, results would support the development of SGM-related healthcare training for oncology APPs.Relevance to clinical practiceTargeted education for providers during training and continuing education is likely to improve the provision of quality care for SGMs with cancer.

Project description:BackgroundHealth care workers (HCWs) involved in day-to-day care and other healthcare activities play a significant role in biomedical waste (BMW) management. The World Health Organization stated some of the causes for the failure of BMW management, namely, lack of awareness of the health hazards related to BMW and inadequate trained HCWs in BMW management. The present study assessed knowledge, attitude, and practice (KAP) towards BMW management among the HCWs in northern Saudi Arabia.MethodologyThe present study assessed KAP through a self-administered and validated questionnaire. Using a multistage probability sampling method, 384 HCWs from different healthcare facilities participated in this survey. We performed binomial logistic regression analysis to find association between KAP subscales and sociodemographic characteristics. Spearman's correlation test was performed to find the strength and direction of correlation (rho) between KAP scores.ResultsOf the population studied, high knowledge, attitude, and practice scores were found in 47.1%, 65.1%, and 49.5% of the HCWs, respectively. The present study found that knowledge score was significantly higher among the age group from 30 to 39 years (ref: age less than 30 years: AOR = 2.25, 95% CI [1.05-4.85], p = 0.04) and non- Saudi nationals (ref: Saudi: AOR = 2.84, 95% CI [1.63-4.94], p < 0.001) The attitude score towards BMW management was significantly lower among the HCWs working in tertiary care settings (ref: PHC: AOR = 0.38, 95% CI [0.12-0.69], p = 0.01). Regarding the practice score, the male categories had a significantly higher score (ref: female: AOR = 1.82, 95% CI [1.19 -2.99], p = 0.02), while pharmacist (ref: physicians: AOR = 0.39, 95% CI [0.18-0.58], p = 0.02) and lab technicians (ref: physicians: AOR = 0.31, 95% CI [0.11-0.53], p = 0.02) had a significant lower practice score. The test results revealed a weak positive correlation of knowledge with the attitude scores (rho = 0.249, p = 0.001), and a moderately strong positive correlation was found between attitude and practice scores (rho = 0.432, p = 0.001).ConclusionThis study suggests that a regular training program for the HCWs on BMW management is necessary through symposiums, role play, interactive lectures, and other feasible training methods. Furthermore, a multicentric prospective exploratory study is to be conducted in other regions of the KSA to understand the region-specific training needs of HCWs.
