The Trump administration terminated the NIH $1.81 billion in less than 40 days, including $544 million in unprovisioned funds.

This is based on an analysis published Thursday in JAMA, which relies on data from the Department of Health and Human Services tracking accountability in a government grant system.

The analysis provides the most comprehensive look to date, with NIH’s funding being cut since the Trump administration began a huge effort to reduce its view as waste and inefficient federal spending.

The study’s author, Michael Liu, a student at Harvard Medical School, said the data remained unfavorable due to the court’s orders, and some grants were temporarily restored due to the court’s orders. He said that despite this, HHS Grant Tracker is still the most accurate and real-time dataset.

From February 28 to April 8, the government terminated nearly 700 gifts from 24 NIH institutes and centers, focusing on subjects such as aging, cancer, child health, diabetes, mental health and neurological diseases.

"These cuts are not spread evenly," Liu said. "That is, the National Institute of Minority Health and Health Disparity hit the hardest. Cuts about 30% of all funding. That's 10 times the average."

President Donald Trump's new budget proposal will remove all funding from the National Institute of Minority Health and Health Disparity next year and call the institute "full of DEI spending." His executive order in January called for an end to programs focusing on diversity, equity and inclusion.

The proposal also calls for a reduction in NIH funding overall, reducing the budget for next year to $27 billion, which would reduce it by about $18 billion to eliminate targeted climate change research and research. The government plans to prioritize research on chronic diseases and other epidemics.

So far, most terminated NIH grants have been allocated to research projects, but about 20% are early career grants for scholarships, training or career development. According to the analysis, larger grants are more likely to be terminated, although it is not clear from the data whether they are targeted directly.

“These larger grants are often funding for large clinical trials and large research centers,” Liu said. “Switching off the lights or preventing patients from receiving medication or interventions can be incredibly destructive.”

Liu said the analysis also showed that the terminated grants have damaged the unity of public and private institutions.

According to the analysis, Columbia University received the most terminations among grant recipients, a total of 157. The Trump administration aims to cut funds, citing “in the face of ongoing harassment by Jewish students, the school has conducted large-scale pro-Palestinian protests on campus, which are ongoing harassment by Jewish students.” Colombia ruled 180 employees this week to engage in federal grants affected by the layoffs.

"Columbia's leadership continues to discuss with the federal government to support the activities of these research awards," top university officials wrote in a letter to the Columbia community. "We are working hard and planning for each situation, but at the same time, the pressure on financial and research missions is strong."
