Significance

CLA-BSIs increase morbidity, mortality and costs. It can be prevented using evidence-based interventions. This measure can be used to detect changes related to implementation or lack of adherence to these best practices.

Sampling Plan / Procedure

• 100% for all patients with one or more Central Lines (CL) as indicated by the presence of T - Central Venous Catheter at 2300 (TISS Item)
  • Starting Oct 1, 2020, the T - Central Venous Catheter at 2300 (TISS Item) is no longer collected . The presence of CVC at 2300 hour is imputed or assigned by inference using this method - if patient is present at 23HR and the T17 - Central venous catheter (TISS Item) is marked, then the patient is assumed to have CVC at 2300 hour.
  • See Central Line for a definition.
• 100% sampling for all cases with CLA-BSI incidence following the criteria listed in CLA-BSI

Definition

The definition follows the definition Central Line.

Frequency

• Recording the date the CLA-BSI occurred.
• Daily recording of dates patients have CL or CVC
• Total number of Central Line days are calculated and reported on a monthly, quarterly or yearly basis based on the daily data.
• Time Reference is calendar month, quarter or year.

Definition and Derivation

CLA-BSI per 1000 Central line days.

Numerator

Number of CLA-BSI incidence during the ICU stay of a reporting period

Denominator

Total Number of Central Line days at 2300 HR of a reporting period

Formula

CLA_BSI Rate Rate = Num / Denom * 1000

Data Sources

• Starting 2019, CLA-BSI is part of the ICD10 collection with code T82.70 Iatrogenic, infection, central venous catheter-related bloodstream infection (CVC-BSI, CLI) under the Acquired Diagnosis / Complication. The date is the Dx Date of the Iatrogenic, infection, central venous catheter-related bloodstream infection (CVC-BSI, CLI) diagnosis.
  • Before 2019, the dates when CLA-BSI occurred were taken from the Tmp project QA Infection.
• Jan 2013 to Dec 2018 Central Line (CVC) days are taken from TISS28 item#46 Central Venous Catheter at 2300 (TISS Item)
• Apr 2008 to Dec 2012 Central Line (CVC) days are collected by CRN and data are saved at S:\MED\MED_CCMED\CCMDB_Special_Projects\Central_Line_Infections_ETube\DATA_ENTRY_LineCounts_ETube
