TABLE 4. Observations on Application Implementation.

Theme	Observations
Impacting shared decision-making	•Prompting decisions by the Vaccine Lead about vaccine preparation rates with Clinic Lead’s updates on patient numbers. •Huddling around the app dashboard to show others the status of the clinic concerning patient intake and vaccine preparation. •Focused conversations about how many extra patients or doses would be required. •Reducing the frequency or length of discussions throughout the day.
Using until the math is easier	•Clinic Lead enters patient intake information until approximately < 10 expected patients are remaining, and the Vaccine Lead has prepared all expected doses. •Clinic Lead is not always ‘zeroing’ the dashboard to balance patient intake numbers with vaccine preparation.
Information-interaction characteristics	Vaccine Lead: •Adding opened vials after pulling a batch. •Adding pooled doses after checking a batch. •Adding wasted doses as they occurred. •Checking for patient updates when entering new vaccine preparation information. •Checking for total patient updates when nearing the end of vaccine preparation. •Only checking for patient updates and not inputting vaccine preparation information. Clinic Lead: •Entering add-ons and no-shows in batches or as they occurred one-by-one. •Entering add-ons and no-shows as a new total value by deleting the old value in the list. •Regularly monitoring the top value change after inputting new information.
Interest in the app	•Showing the app’s interface and functionality to others and explaining to them how they are using it at the clinic to support information tracking and automating calculations.
