Trend analysis for Massachusetts General Hospital
Between 2019 and 2024, Massachusetts General Hospital's Total Case Rate held roughly steady from 3.4 to 3.3 recordable injuries per 100 full-time workers, a 1% decrease across 5 years of OSHA reporting.
The safest year on record was 2021, at a TCR of 3.0, while 2023 saw the highest rate, at 3.8, a spread of 0.8 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 6 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 6 reporting years, Massachusetts General Hospital recorded 4,506 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 6-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)
What is the DART rate formula?
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
227 DART incidents × 200,000 ÷ 47,363,382 hours worked = 0.96 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
