Adherence
Patients who transfer hospitals for secondary MBS are significantly younger, have fewer obesity-related comorbidities (hypertension, GERD), and are more likely to undergo secondary surgery for recurrent weight gain compared to those who stay.
If you are younger and generally healthy but are experiencing weight regain after your first bariatric surgery, you are part of a common group that seeks a second opinion or a different surgeon for revisional surgery. This is often driven by dissatisfaction with the amount of weight lost rather than medical complications.
At baseline, these patients on average were younger (37.9 vs. 42.5, p < 0.001), less often had hypertension or GERD... At secondary surgery... the indication was more often recurrent weight gain (49.0% vs. 23.0%, p < 0.001).
Why this rating
Statistically significant differences (p < 0.001) in a large, matched cohort using robust data linkage methods.

- Secure multi-party computation (MPC) enables the linkage of patient data across different hospitals for research purposes without violating privacy regulations, allowing for accurate assessment of hospital transfer rates.Strong
- Approximately 11.5% of patients undergoing secondary metabolic bariatric surgery (MBS) transfer to a different hospital than their primary procedure, a rate that is underestimated in single-institution registries.Good
