Care transition from a pediatric intestinal rehabilitation program to adult care and the risk of all-cause mortality: A retrospective cohort study

The Transition Gap

A retrospective cohort from Cincinnati Children's tracked 46 intestinal failure patients who turned 20, evaluating outcomes based on whether they transitioned to adult-focused care or remained in the pediatric system 0:13. Of these patients, 59% moved to adult programs while the remainder continued at Cincinnati Children's 0:23.

Mortality Disparity

Patients who transitioned to adult care experienced a 33% mortality rate, compared to 5% among those who stayed in pediatric care 0:29 0:29. This difference occurred despite no apparent differences in medical complexity or disease burden between the two groups 0:29. The median time from transition to death was approximately 12 months 0:42.

What This Means for Trainees

This finding challenges the assumption that transition timing should be driven primarily by chronological age. The data suggest that the infrastructure supporting these patients—not just their underlying disease—determines survival. The first year post-transition represents the highest-risk period 0:42.

The study does not identify which specific elements of adult care contributed to worse outcomes, nor does it establish whether certain transition protocols might mitigate risk. The comparison groups were observational, not randomized, so unmeasured differences in patient selection for transition versus continuation in pediatric care cannot be excluded.

Clinical Implications

Dr. Goddard frames young adults with intestinal failure aging out of pediatric care as "a critically vulnerable population" requiring structured transition programs 0:46 0:46. For trainees managing these patients, the data support aggressive care coordination during the transition year, regardless of apparent clinical stability. The mortality gap suggests that expertise in intestinal failure management, multidisciplinary team structure, or care continuity may be protective—but this study does not isolate which factors matter most.

Until evidence-based transition protocols exist, the decision to transition versus continue pediatric care should weigh this mortality signal against the practical and developmental considerations of adult-focused care.

The Transition Gap

A retrospective cohort from Cincinnati Children's tracked 46 intestinal failure patients through their 20th birthday—the age when most transition from pediatric to adult-focused care 0:13. The outcome disparity was stark: 33% mortality among those who transitioned to adult programs versus 5% among those who remained in pediatric care 0:29 0:29. The two groups showed no obvious differences in medical complexity or disease burden at baseline 0:29.

Timeline and Vulnerability

The median time from transition to death was approximately 12 months 0:42. This compressed timeline suggests the transition event itself—or the immediate post-transition period—represents a discrete high-risk window rather than a gradual divergence in care quality over years.

Of the 46 patients, 59% transitioned to adult-focused programs while the remainder continued at Cincinnati Children's 0:23. The study does not clarify whether continuation in pediatric care was patient preference, insurance-driven, geographic necessity, or clinical recommendation based on unmeasured complexity.

What Remains Unknown

The ledger does not specify causes of death, whether patients maintained contact with any care team during the fatal year, or what specific elements of adult care delivery differed from pediatric management. The claim that groups were similar in complexity and disease burden 0:29 is stated but not operationalized—no metrics for TPN dependence, line infection history, liver function, or transplant status are provided.

The study also does not address whether adult programs had intestinal rehabilitation expertise or whether patients were absorbed into general gastroenterology or surgery clinics without subspecialty continuity.

Implications

For programs managing intestinal failure, this mortality signal is too large to dismiss as selection bias, even with the acknowledged limitations of a single-center retrospective design. Until structured transition protocols are developed and validated, young adults aging out of pediatric intestinal rehabilitation programs remain a critically vulnerable population 0:46 0:46.

The 12-month median to death 0:42 suggests that if intervention is possible, it must happen early—ideally beginning before the transition and extending through at least the first post-transition year.
