Computation description: | For the numerator and the denominator exclude separations where Episode of admitted patient care—admission date, DDMMYYYY is equal to Episode of admitted patient care—separation date, DDMMYYYY. For the numerator, in the case of patients that initially present to an emergency department, 'within 24 hours of presentation to hospital' should be counted from the time that the patient presents to the emergency department (i.e. rather than be counted from the time that they are transferred to a ward). The numerator must include screening for cognitive impairment using a validated tool. There are a range of validated screening tools available (ACSQHC, 2021). Examples include:
The 4AT has been validated both for screening for cognitive impairment and delirium assessment. Administration of the 4AT meets the numerator criteria for this indicator and for Delirium clinical care standard indicators: 4a-Proportion of admitted patients who screened positive for cognitive impairment on presentation to hospital who were then assessed for delirium using a validated tool. Both the numerator and the denominator exclude episodes whereby Episode of admitted patient care—separation mode, code NN corresponds to Died, and this occurs within 24 hours of admission. Presented as a percentage. |
Computation: | (Numerator ÷ Denominator) x 100 |
Numerator: | The number of admitted patients aged 65 years or older or 45 years or older for Aboriginal and Torres Strait Islander people who were screened for cognitive impairment using a validated tool within 24 hours of presentation to hospital. |
Denominator: | The number of patients aged 65 years or older or 45 years or older for Aboriginal and Torres Strait Islander people who were admitted to hospital. |
Comments: | This indicator is based on the Key Principles for Care of Confused Hospitalised Older Persons (ACI, 2014) and the Ontario Senior Friendly Hospital Strategy Delirium and Functional Decline Indicators (Wong et al., 2012). |
