1. The Smoking Cessation CDS protocol was implemented at the Central Clinic one year ago. Of the 500 patients included in the report population, what percentage of patients were seen in the Clinic within the last 12 months?

2. What percentage of patients in the report population were not seen in the Central Clinic within the last 12 months?

3. Based on the data in the report and the implementation period of the Smoking Cessation CDS, what number of patients should be included in the evaluation criteria for the CDS goals?

4. Of the patients who were seen in the clinic during the last 12 months, what percentage have a known smoking status in their problem list?

5. Of the patients who were seen in the clinic during the Smoking Cessation CDS protocol, i.e. during the last 12 months, for what percentage is smoking status unknown, i.e. either not assessed or not documented in the problem list?

6. Of the patients who were not seen in the clinic during the Smoking Cessation CDS protocol, i.e. not seen in the Clinic during the last 12 months, for what percentage was smoking status known, i.e. either current smoker or never smoker?

7. How many more patients who were part of the CDS protocol during the last year have an identified smoking status than patients who were not included in the CDS protocol, i.e. not seen in the Clinic over the last 12 months?

8. Is it much more likely that the Clinic has identified a patient's smoking status under the new CDS protocol? Explain and quantify your answer.

9. Based on the report of Central Clinic patients, was the CDS protocol goal for Smoking Cessation (80% of patients seen in the first year would have a documented smoking status) met? How can you tell?

10. Based on the report of Central Clinic patients, was the CDS protocol goal for Smoking Cessation (100% of patients who currently smoke would be encouraged to quit and provided with smoking cessation literature) met? How can you tell?
