This nationwide stepped-wedge cluster-randomized controlled trial compared evidence-based algorithm-guided care with current practice in 418 patients with chronic pancreatitis across 26 Dutch centers. The algorithm addressed pancreatic insufficiency, nutrition, bone health, pain, and lifestyle. Guided care produced a statistically significant improvement in Izbicki Pain Score (estimate: -1.72, 97.5% CI: -3.02 to -0.41, P < 0.001), but the change did not reach the predefined threshold for clinical relevance. Quality-of-life scores did not significantly improve. The authors reported better outcomes with greater protocol adherence, particularly among patients with severe baseline pain or low baseline quality of life.
Key findings
- Algorithm-guided care improved Izbicki Pain Score (estimate: -1.72, 97.5% CI: -3.02 to -0.41, P < 0.001), but not to the predefined clinically relevant threshold.
- Pancreatitis Quality-of-Life Instrument score showed no significant change (estimate: 0.42, 97.5% CI: -0.44 to 1.27, P = 0.27).
- Median protocol adherence among patients completing follow-up was 68.8% (IQR, 56.1-83.9).
- Subgroup analyses linked greater adherence with better outcomes, especially in patients with severe baseline pain or low baseline quality of life.
Why it matters
The trial suggests that introducing a comprehensive management algorithm does not, by itself, produce clinically meaningful improvements in pain or quality of life across all patients with chronic pancreatitis. The adherence findings point to implementation as an important consideration, while subgroup results suggest that patients with greater baseline burden may warrant particular attention to consistent delivery of recommended care.
What to keep in mind
The reported overall pain improvement did not meet the predefined clinical relevance threshold, and quality of life did not significantly improve. The adherence and baseline-severity findings came from subgroup analyses.
