Timeliness of outpatient follow-up: an evidence-based approach for planning after hospital discharge.21 stand to benefit considerably from timely follow-up. For those whose readmission risk exceeds 20%, our analysis suggests that 1 readmission may be prevented for every 5 patients who receive outpatient follow-up within 14 days. These patients are characterized by having 3 or more chronic conditions, often including advanced coronary artery disease, chronic obstructive pulmonary disease, chronic renal failure, congestive heart failure, diabetes, ischemic vascular disease, or a history of organ transplant, dialysis, or total parenteral nutrition. In this statewide Medicaid population, however, only 51% of patients in high-risk categories received follow-up within 14 days, and for every high-risk patient who did not receive follow-up, there was a low-risk patient who did. Healthier patients and those with greater social support or self-management skills may be better equipped to secure and attend an earlier follow-up appointment, but potentially at the cost of delaying care for those with more complex needs.
