Your improvement team is trying to improve outcomes for patients with diabetes who are younger than age 18. You need a baseline measure for the percent of patients in the population you're studying who have hemoglobin A1c (blood sugar) levels greater than 8. You request this information from your information systems department, located in the central office. Then you wait. And wait. And wait. Frustrated, you decide to take matters into your own hands. Which of the following is the best plan for collecting data? Review all the charts for a four-month period, of which there are 210. Review a sample of the first 40 charts in chronological order. Select a sample of 10 charts from each of the four months to review. Skip baseline data collection because it's not important for this project
