Readmissions, nationally.
What it is
The database built for the readmission question.
The Nationwide Readmissions Database (NRD), part of AHRQ's Healthcare Cost and Utilization Project, links roughly 17 million discharges a year across hospitals within a state, so a patient's return admission is captured wherever it happens. It is the standard source for national 30- and 90-day readmission studies, the outcome that hospitals, payers, and journals care about most.
What it is built for
Scale, ~17 million weighted discharges a year, linked within the calendar year.
Design, readmission rates, causes, predictors, costs, and trends after any index diagnosis or procedure; comparisons between treatments or patient groups.
Limits, no linkage across calendar years or states; no post-discharge mortality; coded data only.
How it works
The method, in plain terms.
Index admission
Diagnosis or procedure codes
Link readmissions
Patient linkage within the year
30-day window
Or 90-day; calendar rules
Causes
Primary diagnosis at readmission
Predictors
Multivariable, survey-weighted
Costs & trends
Charges, LOS, year-on-year
How you benefit
Why authors start here.
- An outcome everyone cares about. Readmission is a quality metric, a cost driver, and a policy target.
- Any condition or procedure. If it is coded, its readmissions can be studied.
- Weeks, not years. The data exists; no recruitment, no follow-up.
- You stay the author. We design and run the study with you to ICMJE standards.
Scope the question
We turn your idea into an index event, a readmission window, and a comparison NRD can answer.
Protocol & codes
Index codes, exclusions, outcomes, covariates, and the weighting plan, pre-specified.
Build the cohort
Index admissions linked to their readmissions, with the calendar-year rules applied honestly.
Analysis
Rates, causes, predictors, costs, and trends, with the checks reviewers expect.
Manuscript
Drafted with you to RECORD/STROBE and formatted to the target journal.
Submit & revise
Journal shortlist, submission package, and reviewer responses to a decision.
