Data from individual patients can be aggregated to provide useful information about various aspects of antibiotic use at ward or hospital level.
In this step we will show some examples of aggregated data collected from 50 patients prescribed antibiotics during a PPS in a small hospital.
This table shows aggregated data on antibiotics used within the hospital. The data from patient 552386 described in Step 2.2 is included within the amoxicillin total.
|Name of drug||Count of prescriptions||Total number of prescriptions and % of total|
|Amoxicillin||IIIII IIIII I||11 (22%)|
|Cefuroxime||IIIII I||6 (12%)|
|Gentamicin||IIIII II||7 (14%)|
This table shows aggregated data on the indications for use of antibiotics within the hospital. The data from patient 552386 in Step 2.2 is included within the COPD total.
Indications for use
|Indication||Count of patients||Total number of patients and % of total|
|Acute abdominal infection||III||3 (6%)|
|Acute exacerbation COPD||IIIII II||7 (14%)|
|Cellulitis||IIIII II||7 (14%)|
|Community acquired pneumonia||IIIII I||6 (12%)|
|Neutropenic sepsis||II||2 (4%)|
|Urinary tract infection||IIIII IIIII II||7 (14%)|
|Wound infection||IIIII II||7 (14%)|
This table shows aggregated data for several measures of the quality of prescribing within the hospital.
The data from patient 552386 in Step 2.2 is included within each of the measures.
Quality of prescribing
|Measure||Count of measure||% for measure|
|Route - number of IV||25/50||50|
|Dose correct (as per policy for indication)||44/50||88|
|Frequency correct (as per policy for indication)||48/50||96|
|Compliance with local policy*||35/48||52|
(Note *) 2 indications were not covered by local policy so could not be assessed)
These tables show the range of information we can collect during a PPS and each one can be used to inform improvements in prescribing practice. We will consider how this type of data can be used later in the week.
