What Society of Interventional Radiology does
Mission
The Society of Interventional Radiology (sir) is a nonprofit, national scientific organization of physicians and allied health professionals deeply committed to improving health and quality of life through the practice of vascular and interventional radiology. Sir promotes education, research, and communication while providing strong leadership in the development of health care policy.
As stated on its FY2024 Form 990.
Programs
Annual meeting and education - sir promotes the profession of interventional radiology by providing an annual scientific meeting for member and nonmember physicians. Other smaller, procedure-specific meetings and educational conferences and seminars are also held throughout the year.
Health policy economics and government affairs - sir takes a proactive role in promoting health policy as well as legislative and research issues pertaining to interventional radiology to key policy decision-makers. Also, the society educates members on the impact the laws and regulations made by key regulatory bodies will have on payment of reimbursements.
Products and publications - sir offers a variety of educational resources to the medical community and the public at large, including the society's journal of vascular and interventional radiology (the journal) and patient information brochures.
The 3 programs described on its FY2024 Form 990, listed largest first by expense.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $14M to $16M (+14%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 6%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.
