2012 Hospital Guide methodology documents

There are a number of different clinical indicators in the Hospital Guide. This section provides detailed information on how these indicators are calculated and where the data comes from. The data period covered by the 2012 Hospital Guide runs from April 2011 through March 2012.

There are four main headings for these documents: Mortality, Efficiency, Clinical Variance and Appendices.

Mortality

• Hospital Standardised Mortality Ratio (HSMR)
• Emergency HSMR (weekday)
• Emergency HSMR (weekend)
• Deaths after surgery (PSI)
• Deaths in low risk diagnosis groups (PSI) (crude rate)
• HSMR toolkit

Efficiency

• Efficiency indicator aggregate score
• Readmissions within one week (crude rate)
• Readmissions within 28 days (adjusted rate)
• Procedures with limited clinical effectiveness (crude rate)
• Short stay admissions without a diagnosis (crude rate)
• Scheduled operations that weren’t performed (crude rate)
• Use of day case surgery
• Long-stay elderly patients (crude rate)
• Long-stay surgical patients (adjusted rate)
• Excess bed days (elective crude rate)
• Outpatients: Rates of follow up
• Outpatients: Rates of attendance
• Operations not performed at the weekend
• Scans available at the weekend
• Bed occupancy by day

Clinical variance

• Ratio of breast reconstruction to mastectomy
• PCI for AMI
• Elective  laparoscopic cholecystectomy (day case rate)

Appendices

• Appendix A – Surgical HRGs
• Appendix B – Medical HRGs
• Appendix C – Derived operating room procedures
• Appendix D – Potential complications of care diagnoses
• Appendix E – Immunocompromised states
• Appendix F – Cancer codes
• Appendix G – Trauma codes
• Appendix H – Low mortality CCS groups
• Appendix M – HSMR basket
• Appendix Q – Procedures of limited effectiveness
• Appendix R – BADS day case procedures
