Web based Clinical Outcome Indicators

INTRODUCTION

This is the biannual update of trends for the following six established hospital acute care patient outcome indicators:

Acute myocardial infarction: survival for 30 days after emergency admission;
Hip fracture: survival for 30 and 120 days after admission;
Selected planned operations: mortality within 30 days of surgery;
Stroke: survival for 30 days after emergency admission;
Surgical readmissions within 7 & 28 days of discharge;
Medical readmissions within 7 & 28 days of discharge.

Figures are available at NHS Board and hospital level for years ending 31st December 1998 ? 2007 and are presented on statistical process control charts.

These indicators were developed under the aegis of Clinical Outcome Indicator reports. These reports are available at http://www.indicators.scot.nhs.uk/Index.htm

INTERPRETATION

Following the dissolution of NHS Argyll & Clyde, NHS Board totals are not presented for NHS Argyll & Clyde. Figures are split into the two new components NHS Argyll & Clyde (Greater Glasgow) and NHS Argyll & Clyde (Highland). The two new components are shown for all years.

ISD Scotland are aware of a problem regarding the recording of ?admission type? on SMR01 for certain Lothian hospitals, relating to PAS system changes. ISD Scotland and NHS Lothian are working closely to fully understand the nature of the problem with a view to fully resolving this as soon as possible. An interim solution has been applied in order to amend the majority of the affected records. The 2006 and 2007 figures for both Lothian and Scotland appear to be affected by this for surgical and medical readmissions. Therefore this data should be treated with caution.
