Sample & Weighting

Sampling:

Hospitals must submit the following variables for all eligible cases. This is necessary because selecting a valid (representative) sample requires this information for the entire population of sepsis cases in a given quarter. In addition, NYS DOH will continue to match the complete case list with the SPARCS inpatient database and provide reports to the hospitals. Further, having a complete list of cases with demographic information and outcome information allows NYS DOH to confirm that those cases included in the CY sample are representative of the entire population of sepsis cases at the high volume hospitals.

Selected data elements required to enable sample selection:

Submission for all eligible cases includes the following variables:

  • Unique Personal Identifier
  • Patient Control Number
  • Date of Birth
  • Gender
  • Medical Record Number
  • Facility Identifier
  • Admission Datetime
  • Discharge Datetime
  • Source of Admission
  • Discharge Status

Sampling Eligible hospitals for 2019

Weighting:

Weighting is based on the total number of cases from each sampling hospital for each particular quarter. The total is the number of adult cases that the hospital would have reported if it had not sampled, based on the full case list submitted by the hospital in the sampling portal. This total is reflected in all 2017 and 2017 onward data in quarterly hospital reports.

Based on the hospital’s sample performance, the estimated numerator and denominator (which represent the total) are provided. The weighted statewide performance is based on each hospital’s (sample) performance and the ratio of number of cases each hospital submitted and total number of cases all hospitals submitted in NY State. The complete weighting methodology is posted under documentation on the portal (https://ny.sepsis.ipro.org/).

If your facility is one of the "sampled" facilities (high volume facilities eligible to submit a sample of their total sepsis cases), then the estimated (weighted) performance (denominators/numerators) will be shown in the quarterly reports.
