Physician-scientists play a unique and critical role in medical research. Nonetheless, a number of trends followed during the 1980s and 1990s revealed that this career pathway was in serious jeopardy. Physician-scientists were declining in number and were getting older. A variety of factors were thought to contribute to this problem, including increasing indebtedness of medical school graduates caused by rapidly rising medical school tuition costs.
To evaluate the impact of recently initiated programs from the National Institutes of Health (NIH) and several not-for-profit institutions designed to revitalize the physician-scientist career pipeline.
We assessed recent trends in the physician-scientist career pipeline using data obtained from the NIH, the American Medical Association, the Association of American Medical Colleges, and other sources.
Total numbers of physicians performing research, grant application numbers and success rates for MDs, MD-PhDs, and PhDs at various stages in their careers, interest in research among medical students, medical school tuitions and postgraduate salaries, numbers and composition of applicants for NIH loan repayment programs, and gender distribution of young physician-scientists.
The number of physician-scientists in the United States has been in a steady state for the past decade, but funded physician-scientists are significantly older than they were 2 decades ago. However, the study of early career markers over the past 7 to 10 years has demonstrated increasing interest in research careers by medical students, steady growth of the MD-PhD pool, and a new burst of activity in the "late bloomer" pool of MDs (individuals who choose research careers in medical school or in residency training), fueled by loan repayment programs that were created by the NIH in 2002. Several recent trends for more established physician-scientists have also suggested improvement.
Although it is too early to assess the impact of these indicators on the long-term career pathway, the recent growth in activity in the physician-scientist career pipeline is an encouraging development. Continued funding of these new programs, coupled with sustained support for physician-scientists committed to the pathway, will be required to maintain these positive trends.
医学科学家在医学研究中发挥着独特而关键的作用。然而,20世纪80年代和90年代出现的一些趋势表明,这一职业道路正面临严重危机。医学科学家的数量在减少,且年龄在增大。人们认为多种因素导致了这一问题,包括医学院学费迅速上涨致使医学院毕业生债务增加。
评估美国国立卫生研究院(NIH)和几家非营利机构近期启动的旨在振兴医学科学家职业发展渠道的项目所产生的影响。
我们利用从NIH、美国医学协会、美国医学院协会及其他来源获取的数据,评估医学科学家职业发展渠道的近期趋势。
从事研究的医生总数、医学博士(MD)、医学博士 - 哲学博士(MD - PhD)和哲学博士(PhD)在其职业生涯不同阶段的资助申请数量及成功率、医学生对研究的兴趣、医学院学费和研究生薪资、NIH贷款偿还项目的申请人数量及构成,以及年轻医学科学家的性别分布。
在过去十年中,美国医学科学家的数量一直处于稳定状态,但获得资助的医学科学家比20年前明显年长。然而,对过去7至10年早期职业指标的研究表明,医学生对研究职业的兴趣在增加,MD - PhD群体稳步增长,并且在2002年由NIH设立的贷款偿还项目推动下,MD群体(即在医学院或住院医师培训中选择研究职业的人)中出现了新的活跃态势。对于更资深的医学科学家而言,近期的一些趋势也显示出改善迹象。
尽管现在评估这些指标对长期职业道路的影响还为时过早,但医学科学家职业发展渠道近期活动的增加是一个令人鼓舞的进展。要维持这些积极趋势,需要继续为这些新项目提供资金,并持续支持致力于该职业道路的医学科学家。
