Public Reporting of Stroke Data

Mechanical Thrombectomy Procedures in Stroke Patients with a Large Vessel Occlusion

The following data reflect our progress as a provider between 2015 and Q1 and Q2 2022. Rhode Island Hospital is the first hospital in the state to be recognized as a Comprehensive Stroke Center by the Joint Commission. This distinction means that we are recognized as health care leaders and are responsible for setting the national agenda in highly specialized stroke care. With our state-of-the-art facility, direct access to neurointerventionalists and streamlined transfer process, our numbers have grown positively since 2015.

Arrival to Arterial Puncture: Rhode Island Hospital Cases

The table below shows the progression of time it took between a patient arriving at the hospital and beginning the arterial puncture procedure. The median time it takes in 2022 to get to the angiography suite from arriving to the hospital is 71 minutes. In the top 25% of cases, it took 56 minutes, while 75% took less than 86 minutes. The average wait time has decreased by 22 minutes since 2015.

Arrival to Arterial Puncture: Transfer Cases

The table below is similar to the previous table, but it indicates the time elapsed between the arrival of patients who came from other medical facilities outside of Rhode Island Hospital and the time of arterial puncture. This is noticeably shorter because these patients arrive with their medical imaging and patient processing having already been completed at the previous facility.

The time between a patient's hospital arrival from medical facilities other than Rhode Island Hospital and beginning the arterial puncture procedure.
Year	Median	25th Percentile	75th Percentile

2016	19	14	29
2017	26	19	72

Arterial Puncture to Recanalization

Recanalization is the process of restoring flow to the brain after a procedure such as this. This table measures the time from the procedure to the time it takes to assess the blood flow in the brain.

The time between a patient's hospital arrival and beginning the arterial puncture procedure.
Year	Median	25th Percentile	75th Percentile
2015	39	25	57.5
2016	23	15.5	38
2017	22	15	35
2018	21.5	15	31

Recanalization Rate

The thrombolysis in cerebral infarction (TICI) scale measures how much blood there is in the brain once the occlusion is removed. The scale ranges from 0-3, with a score of 0 meaning no flow and a very weak outcome, and scores of 2b and higher meaning there is a strong outcome for a positive recovery. We continue to have exceptionally high rates of successful recanalization.

The TICI scale measures how much blood there is in the brain once the occlusion is removed.
Year	TICI 2b and Higher
2015	71.60
2016	86.67
2017	82.87
2018	89.80
2019	91.70
2020	87.80
2021	96.40
Q1/Q2 2022	96.80
