View of physicians on and barriers to patient enrollment in a multicenter clinical trial: experience in a Japanese rural area

A feasibility study of a randomized controlled trial protocol to assess the impact of an eHealth intervention on the provision of dietary advice in primary care

BACKGROUND

Canadian sodium intakes remain high despite population-wide sodium reduction initiatives, highlighting the need for personal action in reducing dietary sodium. eHealth interventions support patients in dietary change and assist clinicians in decision-making and delivering care, including provision of advice. To date, impact of diet-focused eHealth tools, like the Sodium Calculator (SC) dietary screening tool, on clinical outcomes has received minimal examination. This study assessed feasibility of a randomized controlled trial (RCT) protocol to examine the impact of the SC, a physician-focused intervention, on the quality of dietary sodium reduction advice provided by physicians to their patients with hypertension.

METHODS

Primary care physicians from community-based primary care clinics were randomized to one of two groups: (1) 'usual care' for dietary sodium counselling or (2) dietary sodium counselling using the SC ('experimental group'). The primary endpoint was protocol feasibility defined by the following outcomes: process (e.g. recruitment, retention, protocol adherence, acceptability of intervention), resources (e.g. needs, impact on workflow), and management (e.g. staff requirements). Outcomes were assessed using direct observation, interviews, and questionnaires with patients, physicians, and clinic staff.

RESULTS

Seven physicians (n = 4 in experimental group, n = 3 in usual care group) and 65 patients with hypertension (48.5% men, 69.8 ± 10.1 years) successfully participated. The main challenges identified is related to recruitment rate (48% for patients, 20% for physicians) and physician protocol adherence (76%). These improved with minor protocol modifications. There were several areas of protocol success such as no disruption to physician workflow, hiring clinic nurses as research staff, having a physician site lead to support physician recruitment, and a 'Protocol Prompt Form' to increase physician protocol adherence. Importantly, there was a high degree of acceptability of the SC intervention among experimental group physicians [n = 3 (75%)].

CONCLUSIONS

The modified RCT protocol was considered feasible. The identified successes can be leveraged, and the risks can be mitigated, during implementation of a full-scale RCT. Assessment of this RCT protocol is an important step in understanding the effectiveness of diet-focused eHealth tools to supporting physician self-efficacy in assessing, monitoring, and implementing dietary advice in routine clinical practice and supporting patients in effective behaviour change.

Communication barriers between basic scientists and clinicians in regenerative medicine: A qualitative study from Iran

RATIONALE, AIMS, AND OBJECTIVES

Cell-based therapeutics are among the latest advances in health care technologies. The rapid evolution of stem cell science in Iran has necessitated the application of scientific achievements in clinical settings. However, various issues hindered their translation, in particular, impediments in the interactions of basic stem cell scientists and clinicians. We highlighted the impediments in the interactions of stem cell scientists and physicians involved in the opinion of professionals from both groups.

METHOD

This qualitative research was conducted with thematic analysis, performed by purposive sampling. Thirty-two distinguished stem cell scientists and clinicians were interviewed to identify their perspectives on this matter. MAXQDA 2018 was used to classify the axial codes based on factors related to communications inefficiencies. The analysis of coded data recognized 18 subthemes and six major themes.

RESULTS

Central themes include different registers of the two parties, counterproductive clusters hampered networking, external communication barriers, the competition to access resources, leadership conflicts, and the dissatisfaction of stakeholders with their share.

CONCLUSIONS

Most of the impediments were seemingly global, for example, the incoherent medical and basic science educational systems, the vulnerable career path of physician-scientists, and an increasing tendency towards overspecialization. However, some local specific issues were also described, for example, limited funding opportunities and the negative impacts of the division of medical education from the ministry of science, research, and technology in Iran. Proposed interventions include the reinforcement of physician-scientist programs, designing a distributed leadership model, and bringing back the scientific integrity to higher education in Iran.

Nurse awareness of clinical research: a survey in a Japanese University Hospital

BACKGROUND

Clinical research plays an important role in establishing new treatments and improving the quality of medical practice. Since the introduction of the concept of clinical research coordinators (CRC) in Japan, investigators and CRC work as a clinical research team that coordinates with other professionals in clinical trials leading to drug approval (registration trials). Although clinical nurses collaborate with clinical research teams, extended clinical research teams that include clinical nurses may contribute to the ethical and scientific pursuit of clinical research.

METHODS

As knowledge of clinical research is essential for establishing an extended clinical research team, we used questionnaires to survey the knowledge of clinical nurses at Tokushima University Hospital. Five-point and two-point scales were used. Questions as for various experiences were also included and the relationship between awareness and experiences were analyzed.

RESULTS

Among the 597 nurses at Tokushima University Hospital, 453 (75.9%) responded to the questionnaires. In Japan, registration trials are regulated by pharmaceutical affairs laws, whereas other types of investigator-initiated research (clinical research) are conducted based on ethical guidelines outlined by the ministries of Japan. Approximately 90% of respondents were aware of registration trials and clinical research, but less than 40% of the nurses were aware of their difference. In clinical research terminology, most respondents were aware of informed consent and related issues, but ≤50% were aware of other things, such as the Declaration of Helsinki, ethical guidelines, Good Clinical Practice, institutional review boards, and ethics committees. We found no specific tendency in the relationship between awareness and past experiences, such as nursing patients who were participating in registration trials and/or clinical research or taking a part in research involving patients as a nursing student or a nurse.

CONCLUSIONS

These findings suggest that clinical nurses have only limited knowledge on clinical research and the importance to have chances to make nurses aware of clinical research-related issues is suggested to establish an extended research team. Because of the study limitations, further study is warranted to determine the role of clinical nurses in establishing a suitable infrastructure for ethical pursuit of clinical research.

Characteristics of successful recruitment in prospective pediatric pharmacogenetic studies

BACKGROUND

There is a need to explore feasible means of accruing an appropriate study cohort to help fill the knowledge gap between pharmacogenetic contributions to drug response and clinical application in the pediatric population.

OBJECTIVES

The aim of this study was to identify factors affecting recruitment of eligible subjects in pharmacogenetic studies at a large Midwestern pediatric academic medical center. The objectives were to evaluate recruitment success of ongoing trials and ascertain contributors to differential recruitment rates. We hypothesized that studies with good recruitment of eligible subjects would share characteristics not present in studies with lower than anticipated recruitment. The goal was to better understand barriers to good recruitment in pharmacogenetic studies to help inform future trial and infrastructure design.

METHODS

Investigators designed a survey with proposed elements of success, which was then completed by lead and/or site investigators of all pharmacogenetics studies at the institution. Results were evaluated using an investigator-developed likelihood of success scoring system.

RESULTS

Two studies recruited >95% of the approached eligible patients; 4 studies were consistent with investigator-anticipated recruitment (>50%), and 1 study did not meet expected recruitment. A study's total score on the investigator-devised scoring tool correlated well with the proportion of approached patients recruited (Pearson's correlation, r = 0.82; P < 0.001). Multiple factors impacted successful recruitment into these pharmacogenetic studies. Features of studies with successful recruitment included standardized clinical care, an ongoing team-patient relationship, severe and/or life-threatening outcome measures, study coordinator with experience in clinical research, a study medication with few or no alternative treatment options, and active involvement of the research team in clinical care.

CONCLUSIONS

A scoring system for study characteristics may be useful to calculate the risk of failure for successful recruitment, allow discrimination among characteristics contributing to the risk, and permit study design alterations to improve likelihood of successful recruitment in pediatric pharmacogenetic studies.

View and present status of personnel involved in clinical trials: a survey of participants from the First Symposium of the Shikoku Collaborative Group for Promotion of Clinical Trials

Clinical trials leading to drug approval (registration trials) play a central role in the drug development process. Since the introduction of the Good Clinical Practice (GCP) standard in 1997, the Japanese infrastructure for registration trials has improved. The contribution of support staff, including clinical research coordinators (CRCs), to clinical trials is now widely recognized in Japan. Quality issues and career development for these support staff are being increasingly emphasized. The Shikoku Collaborative Group for Promotion of Clinical Trials was organized in 2008 to address these issues through communication with the personnel involved in clinical trials in regional areas of Japan. To understand the views and present status of personnel involved in clinical trials, we used questionnaires to survey the participants of the First Symposium of the Shikoku Collaborative Group for Promotion of Clinical Trials held in August 2009. Group discussions and special lectures occurred at the symposium. The questionnaire began with questions about basic patient characteristics, followed by practical questions. Of 110 participants, there were 68 respondents (62%), including clinical trial support staff (clinical research coordinators [n=36, 53%], administrative officers [n=9, 13%]), and medical staff [n=23, 34%]). Among the support staff, 36 (80%) had more than 5 years of experience. The most common questionnaire answer selected for participation in the symposium was "willing to contact staff from other medical institutions or organizations" for support staff and "to obtain further knowledge concerning clinical trials" for medical staff. The overall view of the discussion ("Was the discussion satisfactory?") was favorable for 36 (53%) respondents. This survey revealed that the group discussion in the present symposium appears to be valuable for participants, using overall satisfaction as a surrogate. Based on the information obtained in the present study, further development of the clinical trial infrastructure, including training opportunities and career development for support staff, is required. Due to the limitations of this study, further analysis is warranted to determine the optimal strategy for training support staff.

Physician participation in clinical research and trials: issues and approaches

The rapid development of new drugs, therapies, and devices has created a dramatic increase in the number of clinical research studies that highlights the need for greater participation in research by physicians as well as patients. Furthermore, the potential of clinical research is unlikely to be reached without greater participation of physicians in research. Physicians face a variety of barriers with regard to participation in clinical research. These barriers are system-or organization-related as well as research-and physician-related. To encourage physician participation, appropriate organizational and operational infrastructures are needed in health care institutes to support research planning and management. All physicians should receive education and training in the fundamentals of research design and methodology, which need to be incorporated into undergraduate medical education and postgraduate training curricula and then reinforced through continuing medical education. Medical schools need to analyze current practices of teaching-learning and research, and reflect upon possible changes needed to develop a 'student-focused teaching-learning and research culture'. This article examines the barriers to and benefits of physician participation in clinical research as well as interventions needed to increase their participation, including the specific role of undergraduate medical education. The main challenge is the unwillingness of many physicians and patients to participate in clinical trials. Barriers to participation include lack of time, lack of resources, trial-specific issues, communication difficulties, conflicts between the role of clinician and scientist, inadequate research experience and training for physicians, lack of rewards and recognition for physicians, and sometimes a scientifically uninteresting research question, among others. Strategies to encourage physician participation in clinical research include financial and nonfinancial incentives, adequate training, research questions that are in line with physician interests and have clear potential to improve patient care, and regular feedback. Finally, encouraging research culture and fostering the development of inquiry and research-based learning among medical students is now a high priority in order to develop more and better clinician-researchers.
