Medicaid Insurance Predicts Increased Postoperative Care Encounters Among Patients on Long-term Opioid Therapy.
Article in Annals of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study examined the association between insurance type and postoperative unplanned care encounters among patients on long-term opioid therapy before surgery. SUMMARY BACKGROUND DATA: Preoperative long-term opioid therapy is associated with unique risks and poorer outcomes following surgery. To date, the extent to which insurance coverage influences postoperative outcomes in this population remains unclear.
methodsAmong individuals receiving a supply of >120 total days or at least 10 opioid prescriptions in the year before surgery, we examined patients with Medicaid or private insurance who underwent abdominopelvic surgery from 2017 to 2021 across 70 hospitals in the state of Michigan. The primary outcome was unplanned care encounters, defined as an emergency department visit or unplanned readmission within 30 days of discharge from surgery. Multivariable logistic regression was used to assess the likelihood of acute care events with insurance type as the primary covariate of interest.
resultsAmong 1212 patients on long-term opioid therapy before surgery, 45.6% (n = 553) had Medicaid insurance. Overall, 1 in 8 (n=151) patients met the criteria for a postoperative unplanned care encounter within 30 days. The probability of an unplanned encounter was 4.5 percentage points higher among patients with Medicaid insurance compared with private insurance (95% CI: 0.5%, 8.4%).
conclusionsAmong patients on preoperative long-term opioid therapy, unplanned care encounters were higher among patients with Medicaid when compared with private insurance. While this is likely multifactorial, differences by insurance status may point to disparities in underlying social determinants of health and suggest the need for postoperative care pathways that address these gaps.
