Primary care providers' cancer genetic testing-related knowledge, attitudes, and communication behaviors: A systematic review and research agenda.

ABSTRACT:

Background

Primary care providers (PCPs) can play a critical role in helping patients receive the preventive health benefits of cancer genetic risk information. Thus, the objective of this systematic review was to identify studies of US PCPs' knowledge, attitudes, and communication-related behaviors regarding genetic tests that could inform risk-stratification approaches for breast, colorectal, and prostate cancer screening in order to describe current findings and research gaps.

Methods

We conducted a systematic search of six electronic databases to identify peer-reviewed empirical articles relating to US PCPs and genetic testing for breast, colorectal, or prostate cancer published in English from 2008 to 2016. We reviewed these data and used narrative synthesis methods to integrate findings into a descriptive summary and identify research needs.

Results

We identified 27 relevant articles. Most focused on genetic testing for breast cancer (23/27) and colorectal cancer risk (12/27); only one study examined testing for prostate cancer risk. Most articles addressed descriptive research questions (24/27). Many studies (24/27) documented PCPs' knowledge, often concluding that providers' knowledge was incomplete. Studies commonly (11/27) examined PCPs' attitudes. Across studies, PCPs expressed some concerns about ethical, legal, and social implications of testing. Attitudes about the utility of clinical genetic testing, including for targeted cancer screening, were generally favorable; PCPs were more skeptical of direct-to-consumer testing. Relatively fewer studies (9/27) examined PCPs' communication practices regarding cancer genetic testing.

Discussion

This review indicates a need for investigators to move beyond descriptive research questions related to PCPs' knowledge and attitudes about cancer genetic testing. Research is needed to address important gaps regarding the development, testing, and implementation of innovative interventions and educational programs that can improve PCPs' genetic testing knowledge, assuage concerns about the appropriateness of cancer genetic testing, and promote open and effective patient-provider communication about genetic risk and genetic testing.

Project description:INTRODUCTION:Intensive behavioral counseling is effective in preventing type 2 diabetes, and insurance coverage for such interventions is increasing. Although primary care provider referrals are not required for entry to the Centers for Disease Control and Prevention (CDC)-recognized National Diabetes Prevention Program lifestyle change program, referral rates remain suboptimal. This study aims to assess the association between primary care provider behaviors regarding prediabetes screening, testing, and referral and awareness of the CDC-recognized lifestyle change program and the Prevent Diabetes STAT: Screen, Test, and Act Today™ toolkit. Awareness of the lifestyle change program and the STAT toolkit, use of electronic health records, and the ratio of lifestyle change program classes to primary care physicians were hypothesized to be positively associated with primary care provider prediabetes screening, testing, and referral behaviors. METHODS:Responses from primary care providers (n=1,256) who completed the 2016 DocStyles cross-sectional web-based survey were analyzed in 2017 to measure self-reported prediabetes screening, testing, and referral behaviors. Multivariate logistic regression was used to estimate the effects of primary care provider awareness and practice characteristics on these behaviors, controlling for provider characteristics. RESULTS:Overall, 38% of primary care providers were aware of the CDC-recognized lifestyle change program, and 19% were aware of the STAT toolkit; 27% screened patients for prediabetes using a risk test; 97% ordered recommended blood tests; and 23% made referrals. Awareness of the lifestyle change program and the STAT toolkit was positively associated with screening and referring patients. Primary care providers who used electronic health records were more likely to screen, test, and refer. Referring was more likely in areas with more lifestyle change program classes. CONCLUSIONS:This study highlights the importance of increasing primary care provider awareness of and referrals to the CDC-recognized lifestyle change program.

Project description:BackgroundDespite efforts to improve access to Medications for Opioid Use Disorder (MOUD), such as buprenorphine, the number of opioid overdoses in the United States continues to rise. In April 2021, the Department of Health and Human Services removed the mandatory training requirement to obtain a buprenorphine waiver; the goal was to encourage more providers to prescribe buprenorphine, thus improving access. Little is known about the attitudes on buprenorphine prescribing after this policy change.ObjectiveThe primary objective was to assess attitudes among primary care providers toward the removal of the buprenorphine waiver training requirement. A secondary objective was to identify other barriers to prescribing buprenorphine.MethodsWe conducted a survey between September 15 and October 13, 2021 to assess the overall beliefs on the effectiveness of MOUD and attitudes toward the removal of the waiver training, current knowledge of buprenorphine, current practice styles related to screening for and treating OUD, and attitudes toward prescribing buprenorphine in the future. This survey was sent to 890 Mayo Clinic primary care providers in 5 US states.ResultsOne hundred twenty-three respondents (13.8%) completed the survey; 35.8% respondents agreed that the removal of the waiver training was a positive step. These respondents expressed a greater familiarity with the different formulations, pharmacology, and titration of buprenorphine. This group was also more likely to prescribe (or continue to prescribe) buprenorphine in the future. Approximately one-third (34.4%) of respondents reported perceived institutional support in prescribing buprenorphine. This group expressed greater confidence in diagnosing OUD, had greater familiarity with the different formulations, pharmacology, and titration of buprenorphine, and was more likely to prescribe (or continue to prescribe) buprenorphine in the future. Respondents who have been in practice for 11 to 20 years since completion of training were most likely to refer all OUD patients to specialists.ConclusionsResults of our survey suggests that simply removing the mandatory waiver training requirement is insufficient in positively changing attitudes toward buprenorphine prescribing. A key barrier is the perceived lack of institutional support. Future studies investigating effective ways to provide such support may help improve providers' willingness to prescribe buprenorphine.

Project description:BackgroundHealthcare providers play a critical role in facilitating patient access to medical cannabis. However, previous surveys suggest only a minority of providers believe that medical cannabis confers benefits to patients. Significant new knowledge about the potential benefits and harms of medical cannabis has recently emerged. Understanding current attitudes and beliefs of providers may provide insight into the ongoing challenges they face as states expand access to medical cannabis.MethodsWe conducted an electronic survey of primary care providers in a large Minnesota-based healthcare system between January 23 and February 5, 2018. We obtained information about provider characteristics, attitudes and beliefs about medical cannabis, provider comfort level in answering patient questions about medical cannabis, and whether providers were interested in receiving additional education.ResultsSixty-two providers completed the survey (response rate 31%; 62/199). Seventy-six percent of respondents were physicians and the average age was 46.3 years. A majority of providers believed ("strongly agree" or "somewhat agree") that medical cannabis was a legitimate medical therapy (58.1%) and 38.7% believed that providers should be offering to patients for managing medical conditions. A majority (> 50%) of providers believed that medical cannabis was helpful for treating the qualifying medical conditions of cancer, terminal illness, and intractable pain. A majority of providers did not know if medical cannabis was effective for managing nearly one-half of the other state designated qualifying medical conditions. Few believed that medical cannabis improved quality of life domains. Over one-third of providers believed that medical cannabis interacted with medical therapies. One-half of providers were not ready to or did not want to answer patient questions about medical cannabis, and the majority of providers wanted to learn more about it.ConclusionsHealthcare providers generally believe that medical cannabis is a legitimate medical therapy. Provider knowledge gaps about the effectiveness of medical cannabis for state designated qualifying conditions need to be addressed, and accurate information about the potential for drug interactions needs to be disseminated to address provider concerns. Clinical trial data about how medical cannabis improves patient quality of life domains is desperately needed as this information can impact clinical decision-making.

Project description:Introduction:Emergency care research in Africa is not on par with other world regions. The study aimed to assess the perceptions and practices towards research among current emergency care providers in Africa. Methods:A survey was sent to all individual members of the African Federation of Emergency Medicine. The survey was available in English and French. Results:One hundred and sixty-eight responses were analysed (invited n = 540, responded n = 188, 34.8%, excluded n = 20). Responders' mean age was 36.3 years (SD = 9.1); 122 (72.6%) were male, 104 (61.9%) were doctors, and 127 (75.6%) were African trained. Thirty-seven (22%) have never been involved in research; 33 (19.6%) have been involved in ?5 research projects. African related projects were mostly relevant to African audiences (n = 106, 63.1%). Ninety-four (56%) participants have never published. Forty-one (24.4%) were not willing to publish in open access journals requesting a publication fee; 65 (38.7%) will consider open access journals if fees are sponsored. Eighty responders (47.6%) frequently experienced access block to original articles due to subscription charges. Lack of research funding (n = 108, 64.3%), lack of research training (n = 86, 51.2%), and lack of allocated research time (n = 76, 45.2%) were the main barriers to research involvement. Improvement of research skills (n = 118, 70.2%) and having research published (n = 117, 69.6%) were the top motivational factors selected. Responders agreed that research promotes critical thinking (n = 137, 81.5%) and serve as an important educational tool (n = 134, 80.4%). However, 134 (79.8%) feel that emergency care workers need to be shown how to use research to improve clinical practice. Most agreed that insufficient emergency care research is being conducted in Africa (n = 113, 67.3%). Discussion:There is scope to increase research involvement in emergency care in Africa, but solutions need to be find to address lack of research-related funding, training and time.
