Five-year overview of donated human milk amounts and quality at a Czech hospital milk bank
Official title: Evaluation of the Quantity and Quality of Human Breast Milk Collected in a Single-center Milk Bank Over the Last Five Years
Run by Charles University, Czech Republic · NCT07309146 · Data updated 2026-11-12
This project looks at donated breast milk from women who gave to the České Budějovice hospital milk bank between 2021 and 2025 to see if maternal and birth factors are linked to how much milk is donated and to routine measures of milk quality.

Is this trial a fit for you?
✓Likely a good fit
Lactating women who donated milk to the České Budějovice Hospital milk bank during 2021–2025 and have at least one recorded donation with basic maternal and perinatal data available.
✕Probably not a fit
Women who did not donate to this milk bank, donors without recorded donation dates or volumes, or records with unverifiable data would not be represented and are unlikely to benefit from this analysis.

What this trial studies
This retrospective, single-center analysis uses anonymized records from the milk bank at České Budějovice Hospital covering 2021–2025. The study will quantify donation frequency and both individual and cumulative volumes of donated human milk. Routine biochemical and microbiological parameters in the hospital database will be used to characterize milk quality. Statistical analyses will examine associations between donation quantity/quality and maternal and perinatal factors such as age, BMI, parity, mode of delivery, and timing of donations.
Why it matters
Potential benefit: If patterns are identified, milk banks could tailor donor recruitment and handling practices to increase safe milk supply for preterm and high-risk infants.
How similar studies have gone: Previous observational analyses have reported links between maternal characteristics and milk composition or volume, so this work builds on existing evidence rather than testing a completely novel concept.

Inclusion Criteria: * Lactating women who donated human milk to the hospital-based human milk bank at České Budějovice Hospital during the period 2021-2025. * Accepted as donors according to local eligibility criteria for human milk donation. * At least one recorded donation of human milk with available data on donation date and volume in the milk bank database. * Availability of basic maternal and perinatal data (e.g., age, BMI, parity, mode of delivery, timing of donation) in the hospital information sys-tem. Exclusion Criteria: * Donors with no recorded volume or date of human milk donation in the milk bank database. * Records with evident data errors or inconsistencies that cannot be reliably corrected (e.g., implausible dates or volumes).
