How 26 Connecticut hospitals compare with the national benchmark on six infections patients can catch in the hospital, and on serious complications, according to Medicare (CMS). Connecticut ranks #8 of 50 states on our infection index.
The Connecticut ratio adds up the infections reported by the state's hospitals and divides by the number CMS predicts; below 1.00 means fewer than predicted. Compare it with the U.S. ratio: CMS's predictions come from a fixed baseline period and infections have fallen since, so most ratios are now below 1.00. Counts show how many Connecticut hospitals CMS rated better than, no different from or worse than national.
| Infection | Connecticut ratio | U.S. ratio | Better | No different | Worse |
|---|---|---|---|---|---|
| Central line infectionsCentral line-associated bloodstream infections (CLABSI) | 0.45 | 0.58 | 7 | 13 | 0 |
| Catheter UTIsCatheter-associated urinary tract infections (CAUTI) | 0.27 | 0.47 | 8 | 13 | 0 |
| Colon surgery infectionsSurgical site infections after colon surgery | 0.77 | 0.83 | 2 | 17 | 0 |
| Hysterectomy infectionsSurgical site infections after abdominal hysterectomy | 1.07 | 1.02 | 0 | 6 | 0 |
| MRSAMRSA bloodstream infections | 0.48 | 0.68 | 5 | 15 | 0 |
| C. diffC. diff intestinal infections | 0.34 | 0.34 | 19 | 6 | 0 |
– means too few predicted infections to calculate a reliable ratio.
Listed from fewest problems to most: hospitals worse on no infection come first, then by how many infections they were better on. Most hospitals are no different from the national benchmark.

Infection index: 1.00 is the U.S. level; lower is better (0.90 means about 10% fewer infections than U.S. hospitals overall, relative to what CMS predicts).

Connecticut ranks #8 of 50 states on HospitalsInEachState.com's infection index (lower is better), at 0.84.

A "worse" result means CMS found the hospital reported significantly more of that infection than predicted during the measurement period. It covers one type of infection over a past period and does not mean every patient is at higher risk. If you have a planned procedure, ask your doctor or the hospital what it is doing about the result and how it applies to your care. In an emergency, go to the nearest emergency room or call 911.
Only hospitals with at least one CMS infection comparison or a serious-complications result are listed. Hospitals with too few procedures or patient days, such as many small rural, critical access and specialty hospitals, often have no comparison. A missing result is not a bad sign. Every hospital still has its own page in the Connecticut hospital directory.
