Table 4.

Comparison of data from administrative databases with data from chart abstraction data for continuous variables

Quality indicator	Nova Scotia (n = 108) ICC^a	Ontario (n = 90) ICC^a
1. Average No. of days between last chemotherapy and death	0.47	0.72
3. Average No. of ER^b visits in last 30 days	0.66	0.33
4.1 Average No. of days in hospital in last 30 days	0.98	0.72
4.2 Average No. of admissions to hospital in last 30 days	0.96	0.44

Intraclass correlation coefficient.

The billings data do not contain a specific hospital indicator. Since administrative data include visits to hospitals other than the reference hospital used for the chart abstraction, agreement statistics will be lower for this indicator.

Note: Since these are continuous variables, actual agreement is not shown.
