SALT is a multi-centre, non-blinded, non-randomized prospective interventional pilot study teaching lactating parents of hospitalized preterm infants how to test their breastmilk sodium (Na) using point-of-care (POC) meters. A drop in Na is a sign of secretory activation in the breast that is associated with adequate short and long-term breast milk volumes in this vulnerable population.
Primary Objective: Establish feasibility, acceptance, and time cost of parent-led parent milk Na testing in the first 14 days postpartum
Secondary Objective: Further investigate relationships between pumping behaviours, lactation risk factors, daily milk Na and lactation outcomes
Exploratory Objective: Explore how POC Na data may be used to modify pumping behaviour and milk volumes

| point-of-care milk sodium testing | Diagnostic Test | Data-driven interventions to improve early lactation success are lacking, and parents who deliver preterm are at high risk of lactation challenges. We will be studying feasibility, acceptability, and time cost of teaching lactating parents of hospitalized preterm infants how to test their breastmilk sodium (Na) using point-of-care (POC) meters. As a secondary aim, we will assess the potential to use these POC sodium results to guide personalized lactation care in the form of altered pumping schedules in an attempt to reduce breastmilk Na. A drop in Na is a sign of secretory activation in the breast that is associated with adequate short and long-term breast milk volumes in this vulnerable population. |
| Measure | Description | Time Frame |
|---|---|---|
| Establish feasibility of parent-led longitudinal parent milk Na testing in the first 14 days postpartum: economic | We will collect time cost of milk testing, including teaching parents how to test milk and daily time testing milk. This outcome will include time (in hours) spent in the first 14 days for parent and staff, with a health economist determining costs for that time | First 14 days postpartum |
| Establish feasibility of parent-led longitudinal parent milk Na testing in the first 14 days postpartum: parent acceptance via interviews | We will collect qualitative data on parent acceptance and feelings about Na testing from parent interviews | First 14 days postpartum |
| Establish feasibility of parent-led longitudinal parent milk Na testing in the first 14 days postpartum: parent acceptance via surveys | We will collect qualitative data on parent acceptance and feelings about Na testing from parent surveys | First 14 days postpartum |
| Measure | Description | Time Frame |
|---|---|---|
| Investigate inter-relationships between pumping frequency, parent lactation risk factors, daily milk Na levels and longer term lactation outcomes (milk provision at NICU discharge). | We will assess interrelationships between aforementioned factors and milk provision at NICU discharge (exclusive, any, none). Note these are not necessarily correlations, but relationships and associations that we will analyze and explore in various models and combinations, so these outcome cannot be separated. |
| Measure | Description | Time Frame |
|---|---|---|
| Explore if POC Na data used to recommend changes in pumping behaviour is associated with actual changes in parent pumping behaviour | Explore in parents whom we recommend to modify pumping frequency, rates of coming to volume by day 14 (pumping at least 500mL/day) | First 14 days postpartum |
| Explore how POC Na data used to recommend changes in pumping behaviour is associated with short-term milk volumes |
