Cost Analysis: Total Cost of Ownership Over 10 Years

When comparing costs, it is vital to consider both direct and indirect costings over a realistic lifecycle. For a mid- sized hospital (np., 300 beds) perfoming 150,000 imageg studios per year, the initival investment for on- premises PACS might be $800,000- $1,2 million for servers, sturage, bureage licenses, and installation. Annual converance, IT salaries, and upgrades may add $200,000- $350,000 per year. Over 1years, thottotal could could could föm $2.8 million toon $4.7 million $4.7 million.
