- See Quality ‘roll-up’ indicator for more information about the purpose and structure of the indicator.
- Review list of additional data (see table on next page) which can be submitted for the expanded data submission of the roll-up indicator. They are organized according to data source. The high-priority indicators (beyond the core D2D 2.0 and ICES data indicators) are shown in bold italics. The lower priority indicators are the remainder in normal type-face.

- Determine how much of that additional data is available, how much effort it would be to access it and the potential increased reliability of the roll-up indicator. See Figure 1 (below) to estimate the incremental increase in reliability with additional data entry. Reliability is measured with a statistic called Cronbach alpha, the most important characteristic of which is that higher values are better.
Figure 1: Reliability of roll-up indicator (source: Patients Canada survey, n= 200, pat weights 4.sav) Figure 1 shows that the roll-up indicator has some reliability even with just core D2D 2.0 indicators (0.587). This increases to 0.697 with the addition of the ICES data from the expanded set of measures listed below. Since these additional indicators are already available to any team that has requested ICES data for D2D 2.0, contributing them may generate increased value in the roll-up indicator without much additional effort. The reliability of the roll-up indicator increases to 0.846 with the addition of the “high priority” indicators listed below. This increase in reliability may need to be balanced by the extra effort associated with getting access to these data. Contributing data from the lower-priority set of indicators does not increase reliability much at all (i.e. increase to 0.855), something teams might weigh against what might be considerable extra effort to access and contribute these data.
- Consult internally with the most appropriate member(s) to decide if your team is interested in contributing to the quality roll-up indicator.
- Compile data for the additional indicators your team is able to contribute.
- Set data aside for submission to D2D 2.0 (see data submission guide).
