Outcome Report

SBNS
Understanding activity pie charts


What does the Consultant activity pie chart show?

The Consultant activity pie charts represent the total number of elective (planned) finished consultant episodes (FCEs) and non-elective (emergency) finished consultant episodes. A finished consultant episode usually represents the care of a single patient from admission to discharge.

Please note that for Consultants who provide both adult services for patients older than 17 years and paediatric services for patients 16 years old and younger there are two outcome reports.

Understanding mortality funnel plot charts

What does the Consultant funnel plot chart show?

The Hospital Consultant mortality funnel plot represent the total number of elective (planned) finished consultant episodes (FCEs) and non-elective (emergency) finished consultant episodes. A finished consultant episode usually represents the care of a single patient from admission to discharge.

The mortality presented here is for three years: April 2014 – March 2017. Please note that for Consultant who provide both adult services for patients older than 17 years and paediatric services for patients 16 years old and younger there are two outcome reports.

The horizontal yellow line represents the national average mortality. The solid black lines above and below the yellow line are the control limits. The upper control limit represents the highest expected mortality rate. The Consultant's outcome is highlighted in magenta.

The outcomes of this consultant are within the expected range

Understanding the risk-adjusted mortality rate

Risk adjustment (or case-mix adjustment) takes into account patient risk factors to calculate a predicted mortality rate. This means that hospitals or consultants who see higher risk patients have their mortality rate adjusted to account for the factors that put these patients at greater risk.

Understanding the 'funnel plot' diagram

The funnel plot displays the risk-adjusted elective procedural mortality ratio for each consultant plotted against the expected number of mortalities for that consultant. The expected number of mortalities for each consultant will vary depending on the number of procedures they have performed and the risk profile of the patients they have treated. The horizontal yellow line represents the expected ratio. The solid black line above the chart is known as a ‘control limit’. This control limit represents the highest expected mortality rate. Risk-adjusted rates appearing beneath this line are within the normal range.
