A recent COSMIN review evaluates the effectiveness of various breastfeeding measurement instruments to standardize clinical assessments. Researchers analyzed 54 studies covering 24 tools to determine their psychometric quality. Despite the variety of options, clinicians often face challenges due to inconsistent findings. This review addresses those challenges by providing a validated evidence base for instrument selection.
Consequently, the study identified seven tools that meet the highest quality standards. These Grade A recommendations include tools for measuring self-efficacy, support needs, and behavior prediction. Moreover, using these breastfeeding measurement instruments can help healthcare providers improve maternal support strategies. Clinicians can now select tools with higher confidence in their psychometric stability.
However, the review also highlights significant evidence gaps in many existing tools. For instance, reliability data were missing for over half of the instruments evaluated. Additionally, fewer than 30% of studies assessed cross-cultural validity or measurement invariance. Furthermore, no instrument has established values for minimal important change or smallest detectable change. Therefore, future research must prioritize closing these critical gaps to enhance clinical utility. Clinicians should focus on using tools with the strongest evidence for reliability and validity.
Seven instruments focusing on maternal self-efficacy, support needs, and breastfeeding behavior prediction received Grade A recommendations for their strong psychometric evidence.
Many tools lack data on reliability, cross-cultural validity, and clinically meaningful change parameters. Future validation research is needed to establish these essential metrics for all recommended tools.

A premature neonate developed upper limb compartment syndrome after uterine rupture extruded the arm through a scar defect. Conservative management with continuous monitoring yielded complete functional recovery and normal limb growth at 10-year follow-up, highlighting non-operative safety in selected cases.

Endoscopic posterior cervical fusion combines minimally invasive decompression, joint preparation, and rigid screw-rod fixation for atlantoaxial pathologies. Early clinical findings demonstrate solid bony union, excellent symptom relief, and minimal soft-tissue morbidity without significant vascular compromise.
