Hepatitis B screening before chemotherapy: a survey of practitioners' knowledge, beliefs, and screening practices.

ABSTRACT:

Purpose

Hepatitis B virus (HBV) reactivation is a potentially fatal complication of chemotherapy that can be largely prevented with medication, provided that asymptomatic HBV carriers are identified. We explored the knowledge, beliefs, and practices of Canadian oncologists/hematologists regarding HBV screening before chemotherapy.

Methods

A novel questionnaire was mailed to all practicing hematologists/oncologists, where publicly accessible online physician registries facilitated identification of these specialists (71% of the Canadian physician population).

Results

Of 504 potentially eligible practitioners, 311 (62%) responded, of whom 246 indicated that they administered chemotherapy and were thus included in final analyses. Respondents tended to underestimate the risk of HBV reactivation, and recognition of the major risk factor for HBV carriage (ie, birth in an endemic area) was low. Forty percent of respondents reported rarely or never testing for HBV before chemotherapy, and 36% reported screening only those patients with HBV risk factors. In multivariate analysis, having a predominantly hematologic practice, practitioner experience with HBV reactivation, ability to correctly estimate the risk of HBV reactivation, fewer years in practice, and female sex were independently associated with an increased likelihood of screening for HBV.

Conclusion

Canadian oncologists and hematologists tend to underestimate the risk of HBV reactivation and report relatively low HBV screening rates. Among those practitioners who do screen, the favored strategy is selective screening of patients with HBV risk factors. However, oncologists'/hematologists' knowledge regarding risk factors for HBV carriage seems to be low, potentially undermining the success of a selective screening strategy.

Project description:BackgroundE-cigarette use is a trend worldwide nowadays with mounting evidence on associated morbidities and mortality. Dentists can modify the smoking behaviors of their patients. This study aimed to explore the knowledge, beliefs, attitude, and practice of E-cigarette use among dental students.Materials and methodsThis multinational, cross-sectional, questionnaire-based study recruited undergraduate dental students from 20 dental schools in 11 countries. The outcome variable was current smoking status (non-smoker, E-cigarette user only, tobacco cigarette smoker only, dual user). The explanatory variables were country of residence, sex, age, marital status, and educational level. Multiple linear regression analysis was performed to explore the explanatory variables associated with E-cigarette smoking.ResultsOf the 5697 study participants, 5156 (90.8%) had heard about E-cigarette, and social media was the most reported source of information for 33.2% of the participants. For the 5676 current users of E-cigarette and/or tobacco smoking, 4.5% use E-cigarette, and 4.6% were dual users. There were significant associations between knowledge and country (P< 0.05), educational level (B = 0.12; 95% CI: 0.02, 0.21; P = 0.016) and smoking status (P< 0.05). The country of residence (P< 0.05) and smoking status (P< 0.05) were the only statistically significant factors associated with current smoking status. Similarly, there were statistically significant associations between attitude and country (P< 0.05 for one country only compared to the reference) and history of previous E-cigarette exposure (B = -0.52; 95% CI: -0.91, -0.13; P = 0.009). Also, the practice of E-cigarettes was significantly associated with country (P< 0.05 for two countries only compared to the reference) and gender (B = -0.33; 95% CI: -0.52, -0.13; P = 0.001).ConclusionThe knowledge of dental students about E-cigarette was unsatisfactory, yet their beliefs and attitudes were acceptable. Topics about E-cigarette should be implemented in the dental curriculum.

Project description:ObjectivesTo describe general practitioners' (GPs') absolute cardiovascular disease risk (ACVDR) self-reported assessment practices and their relationship to knowledge, attitudes and beliefs about ACVDR.DesignCross-sectional survey with opportunistic sampling (October-December 2017).SettingSunshine Coast region, Queensland, Australia.Participants111 GPs responded to the survey.Primary and secondary outcome measuresProportion of GPs reporting a high (≥80%) versus moderate (60%-79%)/low (<60%) percentage of eligible patients receiving ACVDR assessment; proportion agreeing with statements pertaining to knowledge, attitudes and beliefs about ACVDR and associations between these factors.ResultsOf the 111 respondents, 78% reported using the Australian ACVDR calculator; 45% reported high, 25% moderate and 30% low ACVDR assessment rates; >85% reported knowing how to use ACVDR assessment tools, believed assessment valuable and were comfortable with providing guideline-recommended treatment. Around half believed patients understood the concept of high risk and were willing to adopt recommendations. High assessment rates (vs moderate/low) were less likely among older GPs (≥45 vs ≤34 years, age-adjusted and sex-adjusted OR (aOR) 0.36, 95% CI 0.12 to 0.97). Those who answered knowledge-based questions about the guidelines incorrectly had lower assessment rates, including those who answered questions on patient eligibility (aOR 0.13, 95% CI 0.02 to 1.11). A high assessment rate was more likely among GPs who believed there was sufficient time to do the assessment (aOR 3.79, 95% CI 1.23 to 11.61) and that their patients were willing to undertake lifestyle modification (aOR 2.29, 95% CI 1.02 to 5.15). Over 75% of GPs agreed better patient education, nurse-led assessment and computer-reminder prompts would enable higher assessment rates.ConclusionsAlthough the majority of GPs report using the ACVDR calculator when undertaking a CVD risk assessment, there is a need to increase the actual proportion of eligible patients undergoing ACVDR assessment. This may be achieved by improving GP assessment practices such as GP and patient knowledge of CVD risk, providing sufficient time and nurse-led assessment.

Project description:Background: Osteoporosis is an emerging geriatric condition with high morbidity and healthcare cost in developing nations experiencing rapid population ageing. Thus, identifying strategies to prevent osteoporosis is critical in safeguarding skeletal health. This study aimed to evaluate the effects of a bone health screening and education programme on knowledge, beliefs, and practice regarding osteoporosis among Malaysians aged 40 years and above. Methods: A longitudinal study was conducted from April 2018 to August 2019. During the first phase of the study, 400 Malaysians (190 men, 210 women) aged ≥ 40 years were recruited in Klang Valley, Malaysia. Information on subjects’ demography, medical history, knowledge, and beliefs regarding osteoporosis, physical activity status, and dietary and lifestyle practices were obtained. Subjects also underwent body anthropometry measurement and bone mineral density scan (hip and lumbar spine) using a dual-energy X-ray absorptiometry device. Six months after the first screening, similar investigations were carried out on the subjects. Results: During the follow-up session, 72 subjects were lost to follow up. Most of them were younger subjects with a lower awareness of healthy practices. A significant increase in knowledge, beliefs (p < 0.05), calcium supplement intake (p < 0.001), and dietary calcium intake (p = 0.036) and a reduction in coffee intake (p < 0.001) were found among subjects who attended the follow-up. In this study, the percentage of successful referrals was 41.86%. Subjects with osteoporosis were mostly prescribed alendronate plus vitamin D3 by medical doctors, and they followed the prescribed treatment accordingly. Conclusions: The bone health screening and education programmes in this study are effective in changing knowledge, beliefs, and practice regarding osteoporosis. The information is pertinent to policymakers in planning strategies to prevent osteoporosis and its associated problems among the middle-aged and elderly population in Malaysia. Nevertheless, a more comprehensive bone health education program that includes long-term monitoring and consultation is needed to halt the progression of bone loss.

Project description:BackgroundGeneral practitioners (GPs) play an important role in providing patients who smoke with health information, support and treatment to encourage them to quit smoking. Despite conflicting evidence on the effectiveness of electronic cigarettes (e-cigarettes) as a smoking cessation aid, there is growing interest in the role e-cigarettes might play as an alternative to smoking tobacco. This systematic review aims to synthesise evidence from qualitative, quantitative and mixed-methods studies of the knowledge, attitudes, beliefs and social norms of GPs with respect to the use of e-cigarettes as smoking cessation aids.MethodsThis study adhered to the PRISMA guidelines. Studies from MEDLINE, CINAHL, SCOPUS, PsycINFO, EMBASE and grey literature were searched. Two independent reviewers screened abstracts and full-text articles to identify studies that met the inclusion criteria. A data extraction form was used to extract relevant data from included papers and were quality appraised using the MMAT checklist. A PRISMA flow diagram was used to record the flow of papers and reasons for exclusion. Studies were included if they collected quantitative, qualitative or mixed methods data to determine knowledge, attitudes, beliefs and social norms of GPs for use of e-cigarettes as smoking cessation aids.ResultsA total of 4056 abstracts were screened and 25 articles were included. Our findings showed that GPs had mixed views on recommending e-cigarettes as a smoking cessation aid. Some GPs were optimistic and had recommended e-cigarettes to their patients. Others were reluctant and disagreed that e-cigarettes are an effective method to quit smoking. Most GPs lacked knowledge and confidence in having discussions with patients around e-cigarette safety and efficacy as smoking cessation alternatives.ConclusionThis systematic review shows there are mixed views on e-cigarettes as smoking cessation aids. Clear guidance on the role of e-cigarettes is needed to inform and upskill GPs about e-cigarettes for smoking cessation.Prospero registrationCRD42021227612.
