🔬 Practice‑Changing Findings
Evidence from RCTs and meta‑analyses published in the last 12 months.
|
Journal of pediatric gastroenterology and nutrition (2025) - Practice Guideline
Key Findings
- Across chronic GI conditions, anemia frequency increased when inflammatory burden and iron deficiency coexisted rather than presenting as a single isolated mechanism.
- Guideline-concordant comprehensive etiologic evaluation plus treatment of underlying disease activity improved alignment of therapy beyond micronutrient replacement alone.
📋 Practice Implication: When GI disease is present, order parallel inflammation and iron-status workup rather than sequential single-cause testing, so treatment can target both disease control and replenishment from the outset.

Cureus (2025) - Prospective Observational Study
Key Findings
- In 197 older hospitalized adults with anemia, iron deficiency accounted for 31.9%, anemia of chronic disease for 22.8%, and hematologic disorders for 11.2%.
- A standardized panel-based evaluation improved early detection of both common and serious etiologies, supporting broad up-front diagnostic assessment in elderly patients.
📋 Practice Implication: For adults over 64 with new anemia, implement an immediate standard panel (CBC/smear, iron indices, renal/liver profile, B12/folate, occult blood) to reduce missed mixed etiologies and delayed specialist referral.

Annals of clinical biochemistry (2023) - Retrospective Population Study
Key Findings
- Guideline-driven automated decision support increased anemia-related testing compared with routine manual GP workup.
- Enhanced testing increased detection of chronic disease/inflammation anemia, iron-related etiologies, B12/folate deficiency, and potential marrow pathology.
📋 Practice Implication: Adopt reflex or checklist-based anemia pathways in primary care to improve diagnostic yield, particularly for chronic inflammation–related anemia that is frequently under-recognized in routine practice.

Current evidence supports a structured, mixed-etiology approach to anemia workup, especially when chronic inflammatory and iron-deficiency mechanisms overlap. In primary care and inpatient older-adult settings, protocolized testing improves identification of chronic disease/inflammation anemia and reduces underdiagnosis. In patients with chronic kidney disease, integrating hemoglobin trends with inflammatory hematologic markers can improve risk stratification and guide earlier escalation.
