In the last two years, dialysis programs and hospitals across the U.S. have dealt with something they hoped they’d never see at scale:

shortages of IV fluids and peritoneal dialysis (PD) solutions.

These disruptions did not just affect one product line. They touched:

• dialysate and PD solutions,
  
• small- and large-volume saline and dextrose bags,
  
• and associated sterile fluids used in renal replacement and critical care.
  

For patients who rely on hemodialysis, PD, or continuous renal replacement therapy (CRRT), these supplies are not optional. They are life-sustaining.

This article looks at what recent fluid shortages revealed about risk, what has improved, and how 503B outsourcing facilities now fit into dialysis supply planning.

Dialysis Is Built on Sterile Fluids,  More Than Just “Bags”

Dialysis medications and solutions support:

• chronic in-center hemodialysis,
  
• home and in-hospital peritoneal dialysis,
  
• acute kidney injury (AKI) management in the ICU using CRRT,
  
• vascular access maintenance,
  
• fluid and electrolyte balance in fragile patients.
  

It’s not just the dialyzer or the machine that matters. Behind every treatment session, there is:

• a precise fluid composition,
  
• tightly controlled electrolyte profiles,
  
• and sterile circuits that must not be compromised.

What Recent Fluid Shortages Looked Like on the Ground

When supply disruptions hit IV and PD fluids, hospitals and dialysis centers experienced:

• partial or unfilled orders,
  
• strict allocation limits,
  
• last-minute switching between product types,
  
• the need to conserve fluids and prioritize critical patients.
  

Clinical teams had to:

• adjust dialysis prescriptions based on what was available,
  
• re-think PD vs HD usage in some settings,
  
• coordinate closely with pharmacy and materials management,
  
• and communicate carefully with patients about changes to routine.
  

For many organizations, this was a wake-up call: fluid supply is a strategic risk, not a given.

Why Dialysis Programs Are Looking Harder at 503B Outsourcing

Fluid production has traditionally been the domain of large manufacturers, not hospitals. However, outsourcing facilities under section 503B can:

• produce certain sterile solutions and adjunct medications under cGMP standards,
  
• offer validated sterility and endotoxin testing for each batch,
  
• build redundancy in supply for specific dialysis-related products,
  
• and provide documentation that supports risk management and survey readiness.
  

Hospitals are increasingly asking:

• Which of our dialysis-related meds and solutions could be supported by a 503B partner?
  
• How do we create dual-source strategies for high-risk products?
  
• What documentation will we need to show regulators and leadership in the next shortage?

The Role of 503B in Dialysis-Specific Medications and Adjuncts

While not all fluid products can be compounded, 503B facilities can support dialysis programs by preparing:

• certain IV additives and adjunct medications used alongside dialysis,
  
• standardized sterile flushes and maintenance solutions for access devices,
  
• sterile anticoagulation-related preparations when medically appropriate and compliant,
  
• other renal-supportive injectables that must be ready and reliable.
  

This can reduce:

• pressure on in-house compounding,
  
• staff workload in hospital cleanrooms,
  
• and the risk of last-minute improvisation during fluid or drug backorders.
  

What This Means for Nephrology and Pharmacy Leadership

For nephrologists, dialysis program directors, and pharmacy leaders, recent fluid shortages highlight the need to:

• treat dialysis fluids and meds as strategic assets,
  
• map out which products are critical and what their backup plans are,
  
• differentiate between “we’ll figure it out later” and actual dual-sourcing strategies.
  

Key questions include:

• Which medications and solutions are most critical to our chronic and acute dialysis operations?
  
• What percentage of those have no practical substitute if a manufacturer is down?
  
• How can 503B outsourcing facilities help us increase resilience without compromising compliance?
  

How the AllMed Ecosystem Sees Dialysis Supply Risk

• OutSourceWoRx focuses on B2B sterile support, particularly in high-risk sterile medication categories.
  
• AllMedRx emphasizes transparent, safety-first compounding in patient-specific (503A) contexts.
  
• Capital Worx has framed medication shortages — including fluids — as a signal that reliable supply chains are a core investable asset class.
  
• AllergyWorx indirectly feels these stresses when patients with complex conditions see their therapies disrupted, highlighting how intertwined systems are.
  

Together, they represent an integrated view: infrastructure, personalization, and patient-facing education all need to move in sync.

Final Thoughts: Dialysis Fluids as a Strategic Priority

The recent disruptions in dialysis fluids and IV solutions were not a one-off anomaly. They underscored:

• how dependent dialysis is on a steady stream of sterile products,
  
• how quickly systems can be stressed when that stream is disrupted,
  
• and how important it is to build resilient, redundant supply models.
  

503B outsourcing facilities like OutSourceWoRx are now part of that resilience plan — not as a replacement for manufacturer supply, but as a stabilizing partner when hospitals and dialysis centers need it most.
