What can the WHAIC data tell you?

  • Patient detail: This includes information about location of services within a healthcare setting, date of birth, gender, race & ethnicity, ZIP code and census block group. Users may want to:

    • Understand the usage of the ER vs. Urgent Care by patient county of residence, CPT code and diagnosis code.
    • Review data on how many patients were admitted from the emergency department or observation units and reasons for care.
    • Evaluate over or underutilization, total charges and payer details of the inpatient or outpatient departments.
    • Identify a group or subgroup of patients in a specific age range or racial group to review a specific disease, procedure or treatment/services. 
    • Understand the age, race, gender of patients in specific neighborhoods to better understand and relay information on the opioid epidemic or number of flu cases in children or adults.
    • Learn the number of women who get breast exams in any given age range.
