Background

Since 2011, ICNARC has published the Annual Quality Report for the Case Mix Programme (CMP). This is the second year that ICNARC has published results from specialist units. This report makes results from the CMP public to provide a valuable insight into the quality of NHS cardiothoracic critical care units both overall, and at the following levels:

  • Region (England or Wales - Units in Northern Ireland have chosen not to participate in the report)
  • Critical Care Network*
  • Trust or Health Board
  • Hospital
  • Individual critical care unit

97% of all adult, general critical care units in England, Wales and Northern Ireland now participate in the CMP. Following rigorous data validation, all participating units receive regular, quarterly comparative reports for local performance management and quality improvement.

Publication process

The Case Mix Programme (CMP) Annual Quality Report follows a clear publication process:

  1. All participating NHS adult, cardiothoracic critical care units who have collected and submitted data from the period 1 April to 31 March of the reporting year are identified
  2. These units have been asked to agree to public disclosure of their results and have been given the option to consent (or not) to this disclosure
  3. To obtain consent, ICNARC has requested signatures from both the Clinical Director of each participating unit, as well as from the Chief Executive of the Trust
  4. If analysis reveals a participating unit with a potential outlier, ICNARC follows a clear 'Detection and management of outliers' policy (see Appendix: Managing outliers)

For the purposes of analysis, the database was locked on 3 October 2014. Data receieved and/or validated after this date are not included in this report but will be included in the subsequent periodic update.

Participation and coverage

Eligibility criteria for inclusion in the Annual Quality Report for NHS adult, cardiothoracic critical care units for 2013/14 are as follows:

Quality indicators

The Annual Quality Report currently reports on 12 potential quality indicators.

ICNARC has developed several new potential quality indicators for this Annual Quality Report.

Some potential quality indicators provided in previous Annual Quality Reports have been amended or replaced by indicators prescribed by the Clinical Reference Group for adult critical care in relation to specialised commissioning (see Appendix: Clinical Reference Group (CRG)).

The potential quality indicators reported in the Annual Quality Report are as follows:

 

Hospital mortality – risk adjusted (ICNARC and CRG indicator)

  • Hospital mortality is defined as death before ultimate discharge from acute hospital
  • A mortality ratio is calculated by dividing the observed by the expected acute hospital mortality, with the expected estimated by a risk prediction model, a mortality ratio is one (1.0) when the observed and expected acute hospital mortality are equal
  • The ICNARC model was developed and validated using Case Mix Programme (CMP) data and is regularly recalibrated to ensure accuracy
  • The ICNARC risk prediction model describes the relationship between case mix factors (from the first 24 hours following admission to an NHS adult, cardiothoracic critical care unit) and hospital mortality
  • The ICNARC model estimates the expected number of acute hospital deaths for an NHS adult, cardiothoracic critical care unit based on the case mix of its admissions

 

Hospital mortality – risk of death < 20% (ICNARC indicator – new for 2013/14)

  • Definition as per ‘Hospital mortality’
  • Divides the observed number of deaths where risk of death is less than 20% by the expected number of deaths where risk of death is less than 20%, using the current ICNARC models


Hospital mortality – risk of death ≥ 20% 
(ICNARC indicator – new for 2013/14)

  • Definition as per ‘Hospital mortality’
  • Divides the observed number of deaths where risk of death is greater than or equal to 20% by the expected number of deaths where risk of death is greater than or equal to 20%, using the current ICNARC models

 

Unit-acquired Methicillin-resistant Staphylococcus aureus (MRSA) (ICNARC indicator)

  • Presence of MRSA in any sample taken for microbiological examination after 48 hours following admission to the NHS adult, cardiothoracic critical care unit – reported as the rate per 1000 patient days among all patients staying at least 48 hours and excluding those with admission MRSA or no samples taken
  • The comparator value is the overall rate of unit-acquired MRSA from all NHS adult, cardiothoracic critical care units in the CMP for the time period of the report

 

Unit-acquired infection in blood (CRG indicator)

  • Presence of an infection in any blood sample taken for microbiological culture after 48 hours following admission to the NHS adult, cardiothoracic critical care unit (does not include micro-organisms grown from line tip cultures, the same micro-organism cultured repeatedly for the same patient, or infection with Coagulase-negative Staphylococcus) – reported as the rate per 1000 patient days among all patients staying at least 48 hours
  • The comparator value is the overall rate of unit-acquired infections in blood from all NHS adult, cardiothoracic critical care units in the CMP for the time period of the report

 

Non-clinical transfers (out) (ICNARC and CRG indicator)

  • Cardiothoracic critical care unit survivors discharged for comparable critical care to a Level 3 bed in an adult ICU or ICU/HDU in another acute hospital – reported as the percentage of all cardiothoracic critical care unit admissions
  • The comparator value is the overall percentage of non-clinical transfers (out) from all NHS adult, cardiothoracic critical care units in the CMP for the time period of the report

 

Out-of-hours discharges to the ward (CRG indicator)

  • Cardiothoracic critical care unit survivors discharged to a ward in the same hospital between 22:00 and 06:59 – reported as the percentage of all cardiothoracic critical care unit survivors discharged to a ward in the same hospital
  • The comparator value is the overall percentage of out-of-hours discharges to the ward in all NHS adult, cardiothoracic critical care units in the CMP for the time period of the report

 

Daytime discharges to the ward (CRG indicator)

  • Cardiothoracic critical care unit survivors discharged to a ward in the same hospital between 07:00 and 21:59 – reported as the percentage of all cardiothoracic critical care unit survivors discharged to a ward in the same hospital
  • The comparator value is the overall percentage of daytime discharges to the ward in all NHS adult, cardiothoracic critical care units in the CMP for the time period of the report
  • Please note this potential quality indicator is not included on the CMP Quality Indicator Dashboard

 

Out-of-hours discharges to the ward (not delayed) (ICNARC indicator)
