Aim | Methods |
---|---|
1 Evaluate contribution of patient, procedure, postoperative and systems factors following major surgery (with minimum 2-day stay) to develop and validate a readmission risk prediction model. Classify reasons for readmissions and related processes of care. | Acquire and merge retrospective data from the VA Surgical Quality Improvement Program for all assessed surgeries between October 1, 2007 and September 30, 2014 |
Investigate predictors of 30-day unplanned readmission following surgery using logistic regression | |
Develop a risk prediction tool for 30-day unplanned readmission following surgery | |
Determine readmission reason categories from primary ICD9 diagnosis codes | |
Report findings to National Surgery Office Advisory Board | |
2 Assess potential patient factors not currently collected by VASQIP for association with readmission | Develop and pilot a prospective survey to assess patient psychosocial factors at discharge |
Recruit 800 surgical patients from four (4) VA sites distributed across the nation | |
Administer prospective survey prior to discharge and follow patients for 30Â days post-discharge to assess readmission | |
Assess the association between psychosocial factors not currently assessed in administrative data and 30-day unplanned readmission in the prospective cohort | |
Further explore predictors of 30-day unplanned readmission following surgery using psychosocial factors | |
3 Rank reasons for readmission based on Aim 1 and Aim 2 and assess for potential preventability and appropriateness for classification as a measure of surgical quality. | Develop Delphi process form using readmission reasons defined in Aim 1 |
Convene Delphi panel participants | |
Rank readmission reasons as (1) potentially preventable and (2) appropriate measures of surgical quality | |
Report findings to National Surgery Office Advisory Board |
