Trends in clinical trial investigator workforce and turnover: An analysis of the U.S. FDA 1572 BMIS database.

ABSTRACT:

Background

High turnover rates among clinical trial investigators contribute to inefficiency, instability, and increased costs for the clinical research enterprise; however, factors contributing to investigator turnover have not been well characterized.

Methods

Using information from the U.S. Food and Drug Administration's Bioresearch Monitoring Information System (BMIS), we examined trends in the overall clinical investigator workforce and within specific "phenotypes" as well as differences by investigator location (U.S.-based vs. non-U.S.-based). We identified unique investigators within the database, stratifying them into one of three "phenotypes": those with one Form FDA1572 submission across the study interval ("one-and-done"); those with two or more submissions but with substantial intervals between trials ("stop-and-go"); and those with two or more submissions and continuous involvement in multiple trials ("stayers").

Results

Of the 172,453 unique investigators who submitted a Form FDA 1572 during the study interval (1999-2015), 85,455 were classified as "one-and-done" investigators; 21,768 as "stop-and-go" investigators; and 65,231 as "stayer" investigators. The total number of investigators declined across the study interval. Among all subgroups, only "one-and-done" investigators showed growth across the study period, largely driven by increases in non-U.S.-based investigators. "Stop-and-go" investigators showed declines for both U.S.-based and non-U.S.-based investigators, as did "stayers," who showed the largest absolute and proportional declines of all subgroups.

Conclusions

From 1999 to 2015, investigators submitting a Form FDA 1572 to the BMIS database declined by approximately one-third and the proportion of investigators involved in only one trial increased, signaling potential adverse trends in the clinical investigator workforce. Strategies for sustaining investigator engagement warrant further exploration.

Project description:Analysis of the nursing registration databases is a highly informative approach that provides accurate and reliable information supporting evidence based decisions relevant to the nursing workforce planning, management and development. This study presents the first systematic analysis of the nursing registration database in Lebanon. It Reports on the workforce distribution and trends using an updated version of the Order of Nurses in Lebanon (ONL) databases.This study presents a secondary data analysis of a de-identified subset of the updated ONL registration database. The workforce participation status of ONL registered nurses was categorized as active and eligible. For active nurses sectors and sub-sectors of employment were defined. Eligible nurses were categorized as unemployed, working outside nursing and working abroad. SPSS was used to conduct descriptive analysis to present workforce trends of Lebanese nurses for year 2009-2014 as frequencies, percentages and percentage changes.Increases in the size of the Active (35%) and Eligible (86%) nurses were observed over the past six years. The majority of nurses fell in the below 35 years age group (60% in 2014). The hospital sector remained the principle employer, with 87% of Lebanese nurses working in hospitals in 2014. A 173% increases was reported for nurses working abroad.Despite the growth of the Active nursing workforce, the skewed distribution of nurses in the below 35 age group and the growth in the Eligible category, especially for nurses living abroad, raise concerns on the longevity of nurses in the profession and the reasons for their attrition from the workforce.There is a need to investigate the push and pull factors that are affecting nurses and the design of policies and interventions that would encourage nurses to remain active in Lebanon. Furthermore, policies and interventions that would create employment opportunities outside hospitals, especially in the Community sector, are recommended.

Project description:BackgroundMost U.S. studies on workforce preparedness have a narrow scope, focusing primarily on perceptions of clinical staff in a single hospital and for one type of disaster. In contrast, this study compares the perceptions of workplace disaster preparedness among both clinical and non-clinical staff at all U.S. Department of Veterans Affairs (VA) medical facilities nationwide for three types of disasters (natural, epidemic/pandemic, and manmade).MethodsThe VA Preparedness Survey used a stratified simple random, web-based survey (fielded from October through December 2018) of all employees at VA medical facilities. We conducted bivariate and multivariate logistic regression analyses to compare the sociodemographic characteristics and perceptions of disaster preparedness between clinical and non-clinical VA staff.ResultsThe study population included 4026 VA employees (2488 clinicians and 1538 non-clinicians). Overall, VA staff were less confident in their medical facility's ability to respond to epidemic/pandemics and manmade disasters. Depending on the type of disaster, clinical staff, compared to non-clinical staff, were less likely to be confident in their VA medical facility's ability to respond to natural disasters (OR:0.78, 95% CI:0.67-0.93, p < 0.01), pandemics (OR:0.82, 95% CI:0.70-0.96, p < 0.05), and manmade disasters (OR: 0.74, 95% CI: 0.63-0.86, p < 0.001). On the other hand, clinicians, compared to non-clinicians, were 1.45 to 1.78 more likely to perceive their role in disaster response to be important (natural OR:1.57, 95% CI:1.32-1.87; pandemic OR:1.78, 95% CI:1.51-2.10; manmade: OR:1.45; 95% CI: 1.23-1.71; p's < 0.001), and 1.27 to 1.29 more likely to want additional trainings to prepare for all three types of disasters (natural OR:1.29, 95% CI:1.10-1.51; pandemic OR:1.27, 95% CI:1.08-1.49; manmade OR:1.29; 95% CI:1.09-1.52; p's < 0.01). Clinicians were more likely to be women, younger, and more educated (p's < 0.001) than non-clinicians. Compared to clinicians, non-clinical staff had been employed longer with the VA (p < 0.025) and were more likely to have served in the U.S. Armed Forces (p < 0.001).ConclusionsThese findings suggest both a desire and a need for additional training, particularly for clinicians, and with a focus on epidemics/pandemics and manmade disasters. Training programs should underscore the importance of non-clinical roles when responding to disasters.

Project description:Pluripotent stem cells (PSCs) hold great potential for novel therapeutic approaches to regenerate or replace functionally impaired tissues. Since the introduction of the induced pluripotent stem cell technology in 2006, the number of scientific publications on this topic has constantly been increasing. However, so far no therapy based on PSCs has found its way into routine clinical use. In this study, we examined research trends related to clinical trials involving PSCs based on data obtained from ClinicalTrials.gov, the ICTRP database from the World Health Organization, as well as from a search of all individual databases that are included in the ICTRP using a multistep search algorithm. Following a stringent inclusion/exclusion procedure 131 studies remained that could be classified as clinical trials involving PSCs. The magnitude of these studies (77.1%) was observational, which implies that no cells were transplanted into patients, and only a minority of studies (22.9%) were of an interventional study type. The number of clinical trials involving induced pluripotent stem cells (iPSCs, 74.8%) was substantially higher than the one involving embryonic stem cells (ESCs, 25.2%). However, the picture changes completely when focusing on interventional studies, where in the majority (73.3%) of cases ESCs were used. Interestingly, also the study duration was significantly shorter for interventional versus observational trials (p = 0.002). When focusing on the geographical study regions, it became obvious that the greatest part of all observational trials was performed in the USA (41.6%) and in France (16.8%), while the magnitude of interventional studies was performed in Asian countries (China 36.7%, Japan 13.3%, South Korea 10.0%) and in the field of ophthalmology. In summary, these results indicate that only a limited number of trials were focusing on the actual transplantation of PSCs into patients in a rather narrow field of diagnoses. The future will tell us, if the iPSC technology will ultimately overcome the current challenges and will finally make its way into routine clinical use.
