An Update to the Physician Shortage Problem

The AAMC (Association of American Medical Colleges) has released new projections indicating a physician shortage of up to 86,000 physicians in the United States by 2036. This underscores the critical need for sustained and increased investments in training new physicians to address the country’s healthcare needs. The report, conducted by GlobalData Plc, includes various scenarios based on trends in healthcare delivery and the workforce. While the projected shortfall is smaller than previous estimates, it still highlights the necessity for additional investments in graduate medical education (GME). Demographics, particularly population growth and aging, are driving the increasing demand for physicians. The report also notes a significant portion of the physician workforce nearing retirement age, which will further decrease the physician supply. Addressing underserved communities could require approximately 202,800 more physicians than current estimates. Lifting the federal cap on Medicare support for GME and bipartisan legislation like the Resident Physician Shortage Reduction Act aim to alleviate the shortage, but further efforts are needed to meet future healthcare demands.


Rural Americans’ Healthcare Challenges

Rural Americans face significant healthcare challenges, with fewer available doctors compared to urban areas, exacerbating existing health issues. Dr. Bruce A. Scott, President of the American Medical Association, emphasizes the urgent need for policymakers to address these disparities. Rural communities experience higher rates of various illnesses, exacerbated by economic pressures and limited access to healthy living conditions. The shortage of specialists and the closure of rural hospitals further compound the problem. Insufficient access to primary care physicians is a pressing issue, with inadequate residency spots and decreasing applications from rural areas. The AMA advocates for changes to the Medicare physician payment system, which has seen a decline in rates over the years. Administrative burdens, such as prior authorizations, are also contributing to physician burnout and compromising patient care. To combat the doctor shortage and rural health challenges, the AMA advocates for healthcare reforms, including overhauling the Medicare payment system, expanding telehealth, increasing residency positions, incentivizing rural practice, and addressing workforce stresses.

History of the IHS: Indian Health Services

When experts study health across various U.S. demographics, one particular metric often falls into sharp relief: there is a significant health burden weighing on American Indians and Alaska Natives. The AI/AN population accounts for about 9.7 million people in the United States (about 2.9% of the population), and this group routinely ranks near the bottom for life expectancy, insurance coverage, and overall health (both mental and physical).

About 2.6 million of AI/AN people receive healthcare services from the IHS, or Indian Health Services. This program aims (to use their own words), “to raise the physical, mental, social, and spiritual health of American Indians and Alaska Natives to the highest level,” but is the program succeeding? Let’s examine the IHS and its mission, challenges, and efficacy.

The IHS Story

While the U.S. government and federally recognized tribes have worked in partnership to provide AI/AN people with healthcare since the 1700s, the IHS officially began its work in July of 1955. The organization first worked to build hospitals in remote parts of the country that served Native individuals in the area; over the years, the IHS has expanded its efforts to include both health services and public health education.

Today, the IHS is a part of the U.S. Department of Health and Human Services. They operate more than 600 medical facilities on or near Indian reservations across 37 states, and they also work to tackle challenges impacting AI/AN public health.

Challenges Facing the IHS

There’s no arguing that the IHS has laudable goals and that its team of 15,000 employees works hard to improve AI/AN lives. But IHS still faces significant challenges in its efforts. Research shows that about 61% of IHS medical buildings are in “fair” or “poor” conditions, which severely limits medical professionals’ ability to treat their patients. Similarly, many IHS facilities report working with broken or unreliable equipment, which affects the standard of care they can provide.

Furthermore, many IHS buildings are located in remote, rural locations with few amenities like grocery stores, schools, or even adequate housing. This makes recruiting and retaining medical staff especially difficult and limits the pool of quality professionals willing to practice in their network (notably, 50-75% of physicians who contact IHS recruiters have conduct or licensure issues on their record).


Despite these challenges, the IHS continues to make changes that benefit AI/AN peoples across the country. For example, in 2022 the IHS fought to secure $3.5 billion in funding from the government that allowed them to improve water supplies and wastewater disposal systems on tribal lands. Efforts like these help American Indians and Alaskan Natives improve their health and enjoy a better quality of life, and they prove that organizations like the IHS offer a tremendous benefit to the people they serve.

Study Suggest that Cancer Death Risk From Low-Dose Radiation Is Underestimated

A recent study featured in the British Medical Journal unveils concerning associations between extended exposure to low-dose radiation, commonly experienced by nuclear industry workers, and amplified cancer-related mortality. Drawing insights from the International Nuclear Workers Study (INWORKS) encompassing data from over 300,000 workers, researchers discovered a stark reality: for each cumulative unit of radiation exposure, the risk of death from solid cancer surged by 52%. Even at the lowest cumulative doses, this risk doubled, challenging the assumption that low-dose exposures present less carcinogenic hazard. While the absolute risk remains small, these findings prompt reconsideration of safety limits for workers and call for further studies to confirm the accelerated risk of cancer with ionizing radiation exposure. The hope is that regulatory bodies will integrate these insights into revising protection standards for individuals exposed to low-dose radiation.


In a study published in Medical Hypotheses, a French group presented a theory regarding the brain fog experienced in long COVID, based on brain patterns identified in patient PET scans. They propose that inflammation triggered by COVID-19 disrupts astrocyte cells’ regulation of glutamate, impacting energy metabolism and leading to cognitive fatigue. The authors suggest targeting this malfunction with therapies focused on astrocytic glutamate regulation as a potential way to alleviate long-COVID neurological symptoms. They highlight the lack of mental clarity, difficulty concentrating, and cognitive strain characterizing long COVID, affecting up to 15% of patients after three months of the initial infection. This study builds on previous findings of hypometabolism patterns in long COVID patients’ brain images and explores cellular mechanisms, including links between glutamate dysregulation and cognitive fatigue from other studies. Drawing parallels with “chemo-fog” in cancer patients and cognitive impairment in Parkinson’s disease, the authors suggest therapeutic strategies targeting the identified brain patterns, citing examples from epilepsy treatments and a recent study using medication to improve cognitive function in long-COVID patients. However, the authors stress the need for further research, proposing PET imaging studies using specific markers to comprehend astrocyte function and glutamate regulation for a comprehensive understanding of long COVID’s underlying mechanisms.

MRIs and Past Cannabis Users

At the International Society for Magnetic Resonance in Medicine (ISMRM) annual meeting, New Zealand researchers presented findings on heavy cannabis use in adolescence to early adulthood and its correlation with brain structure differences in hippocampus and amygdala subregions. The study, led by medical physicist Rebecca Lee and colleagues from the University of Otago in Christchurch, indicated volumetric disparities in these brain regions among heavy cannabis users compared to non-using controls. Notably, past cannabis users showed smaller volumes in specific hippocampal and amygdala subregions. However, the research did not find detectable differences in cerebral blood flow or white-matter tract integrity related to cannabis use, suggesting potential transient brain changes or no long-term effect on these properties. The study, conducted using MRI techniques, emphasized the need for longitudinal studies to clarify the causation and long-term functional impacts of these structural brain changes associated with heavy cannabis use. Despite revealing structural brain changes linked to cannabis use, the study does not definitively establish a causal relationship between these changes and cannabis consumption. Further prospective longitudinal MRI studies are essential to elucidate causality in this context.
