# How do you calculate hospital acquired infection rate?

## How do you calculate hospital acquired infection rate?

1. given period: month, quarter, year.
2. = Number of patients infected *100.
4. In this rate a patient with 2 infections is counted only once.

## What is a standardized infection ratio?

The Standardized Infection Ratio (SIR) is a statistic used to track healthcare associated infections (HAIs) over time, at a national, state, or facility level. The SIR compares the actual number of HAIs at each hospital, to the predicted number of infections.

Is a CAUTI a HAC?

–Catheter-Associated Urinary Tract Infection (CAUTI) HAC scores range from -3 to +3, with -3 representing a good score and +3 representing a bad score. Hospitals with total HAC scores in the bottom 25th percentile (the worst-performing hospitals) face a 1% reduction in payment.

How do you calculate infection control rate?

To calculate a CAUTI rate, divide the number of people in the surveillance area who met the criteria for a new CAUTI by the number of urinary catheter days in the surveillance area for the same time period, and multiply the result by 1,000.

### What is the benchmark for Clabsi?

CLABSI Surveillance, Benchmarking, and Public Reporting Surveillance involves systematically collecting, analyzing, interpreting, and disseminating data to members of the health care team as a means to facilitate improvement in patient outcomes.

### How is Clabsi Sir calculated?

The SIR calculation is based on dividing the total number of observed CLABSI events by an “expected” or “predicted” number using the national CLABSI rates. This “expected” number is calculated by multiplying the national CLABSI rate by the observed number of central line-days for the specific location.

How is Clabsi rate calculated?

CLABSI Rate Analyses The CLABSI rate is calculated per 1,000 central line-days by dividing the number of CLABSIs by the number of central line-days and multiplying the result by 1,000.

What is a good HAC score?

Top 50 Hospitals by HAC Score

Hospital Name HAC Total Score
1. Mayhill Hospital -1.92
2. St. Vincent’s Chilton -1.92
3. Indiana Orthopaedic Hospital -1.87
4. Kansas Surgery & Recovery Center -1.87

## What does a SIR of 1.07 mean?

In other words, an SIR greater than 1.0 indicates that more HAIs were observed than predicted; conversely, an SIR less than 1.0 indicates that fewer HAIs were observed than predicted.

## How are urinary catheter days calculated?

The CAUTI rate per 1000 urinary catheter days is calculated by dividing the number of CAUTIs by the number of catheter days and multiplying the result by 1000. The Urinary Catheter Utilization Ratio is calculated by dividing the number of urinary catheter days by the number of patient days.

How is Clabsi measured?

Hospital registration systems provided the total number of patient-days per unit each month. The device utilization ratio was calculated by dividing the number of central line–days by the number of patient days; the researchers concluded that this ratio provided a reasonable estimate to use in calculating CLABSI rates.

How do you calculate central line days?

Central line-associated bloodstream infection (CLABSI) rate If a hospital intensive care unit (ICU) had 5 infections and 100 central line-days, their rate would be calculated as follows: 5/100 = . 05 infections per central line-days X 1000 = a rate of 50 central line infections per 1000 central line-days.

### How do you calculate central line utilization ratio?

The device utilization ratio was calculated by dividing the number of central line–days by the number of patient days; the researchers concluded that this ratio provided a reasonable estimate to use in calculating CLABSI rates. 1.

### What is total HAC score?

A Hospital’s Total HAC Score is defined by CMS as the sum of weighted Domain 1 and Domain 2 scores.
