Table 3. Summary of quantitative measures for implementation outcomes.

Outcome	Description	Data source	Measurement approach	Target	Measurement time point
Reach	Number and representativeness of patients who register to REACH and who consent to have their data used for research.	REACH system	The number and representativeness of registered patients (ie, cancer type, age, sex, treatment status, time since diagnosis, time registered to system).	Registration – none.Research consent – >60%.	Monitored every 4 months to help identify and inform necessary changes to the implementation strategies used to facilitate patient awareness and uptake.
Feasibility	The extent to which REACH can be successfully used by patients.	REACH system	Time to open screening questions.	75% are opened within 7 days of initial prompt.	Monitored every 4 months to help identify and inform necessary changes to the REACH system and/or implementation strategies used to facilitate the completion of assessments.
			Time to complete screening questions.	None	Monitored every 4 months to help identify and inform necessary changes to the REACH system and/or implementation strategies utilised to facilitate the timely completion of assessments.
		Patient survey	REACH feedback survey (questions on the amount of time and frequency of reporting symptoms).	75% of patients scored 2 (just right) on the patient feedback form feasibility questions.	Survey will be sent at 12 and 16 months.
Acceptability	The extent to which REACH is appealing, satisfactory and welcomed.	Patient survey	REACH feedback survey (questions from the AIM about the REACH system).	75% of patients had an average score of ≥4 (agree).	Survey will be sent at 12 and 16 months.
Appropriateness	The extent to which REACH is fitting, suitable, applicable for the patient population.	Patient survey	REACH feedback survey (questions from the IAM about the REACH resources).	75% of patients had an average score of ≥4 (agree).	Survey will be sent at 12 and 16 months.
Fidelity	The extent to which REACH was used as intended.	REACH system	Completion of screening questions.	75% of all assessments scheduled were completed.	Monitored every 4 months to help identify and inform necessary changes to the REACH system and/or implementation strategies used to facilitate the completion of assessments.
			Clicks on the REACH resources recommended to patients.	75% of patients clicked on at least one resource recommended.	Monitored every 4 months to help identify and inform necessary changes to the REACH system and/or implementation strategies used to facilitate the use of the resources offered to patients.
