Almost every reporting problem we are called about is described the same way: the numbers do not match. Finance has one figure, the clinical director has another, and both were produced from eClinicalWorks. The report is rarely the culprit. The definitions underneath it are.
Write the specification before you build
A report request that arrives as a sentence produces a report nobody trusts. Before development, write down the purpose, the filters, the date basis, the expected row count order of magnitude, and the person who signs off. Ten minutes of specification prevents three rounds of revision.
Fix the date basis first
Service date, posting date, claim submission date and payment date will all give you a defensible but different monthly total. Pick one per report, state it on the report itself, and make sure every report in a related family uses the same one. This single discipline resolves more discrepancies than any other change.
Reconcile against a known source
A report is not finished when it runs. It is finished when its output has been compared against something independently known to be true: a clearinghouse total, a bank deposit, a manually counted day of encounters.
Publish the definitions
Maintain a short data dictionary in language a practice manager can read. What counts as a visit. When a patient becomes inactive. Whether a no show is a cancellation. Departments stop producing conflicting numbers when they stop inventing private definitions.
Fewer reports, better maintained
Most libraries we inherit hold hundreds of reports, of which maybe eight do real work. Retire what nobody runs, validate what matters, and name the survivors so people can find them. A library of twelve trusted reports beats three hundred unverified ones.
Plan for the upgrade
Reports that depend on custom fields or unusual joins are the ones an upgrade breaks. Flag them during the build and test that list after every version change. The failure mode to avoid is not a report that errors out, it is one that runs and quietly returns the wrong number for two months.
