Maintaining Quality and Safety

Ensuring quality requires robust testing protocols, thorough documentation, ongoing staff training, and regular environmental monitoring. Strong quality control measures have been shown to increase revenue by an average of 11%.

Production Volume and Growth

503B facilities can produce larger batches without prescription requirements, reducing per-unit costs. Outsourcing offers several advantages, such as:

  • Consistent quality through validated processes

  • Scalable production capacity

  • Dedicated quality control teams

  • Comprehensive environmental monitoring

These benefits make outsourcing an efficient solution for handling higher production demands.

Strategic Service Selection

Consider outsourcing complex tasks like high-risk sterile compounding, large-batch production, quality testing, and environmental monitoring. This allows your pharmacy to focus on its core services while staying aligned with regulatory requirements and operational goals.

Top Tasks to Outsource

High-Risk Sterile Compounds

Producing high-risk sterile compounds demands specialized facilities and strict quality control. Many pharmacies outsource this work to reduce risks and maintain consistent standards. This approach allows them to focus on their main services while meeting CGMP requirements. Additionally, outsourcing is a practical solution when internal resources are stretched, enabling smooth large-scale production.

Large-Scale Production

When production needs surpass what in-house teams can handle, 503B facilities become a valuable resource. These facilities are equipped for batch manufacturing while adhering to CGMP standards and undergoing routine FDA inspections. Outsourcing here means access to established manufacturing processes, dedicated quality control teams, and efficient batch processing systems.

Lab Testing Services

Lab testing plays a critical role in ensuring the quality of compounded products. By outsourcing these services, pharmacies can simplify their operations and focus on their core responsibilities. Common outsourced tests include verifying active ingredient levels, sterility checks, stability testing for beyond-use dating, and environmental monitoring to maintain compliance.

Clean Room Management

Managing clean rooms that meet FDA standards requires significant investment and expertise. Outsourcing clean room management can cover tasks like environmental monitoring, facility audits, and staff training to uphold strict cleanliness and process controls. Regular inspections by external partners add another layer of quality assurance, ensuring continued compliance.

Pros and Cons of Outsourcing

Benefits of Outsourcing

Outsourcing compounding tasks can bring major advantages to pharmacy operations. According to the Pharmaceutical Research and Manufacturers of America, nearly 3.6 billion prescriptions are dispensed annually in the U.S., with around 30 to 40 million being compounded medications. This high demand makes outsourcing a practical choice for many healthcare facilities.

One key advantage is improved regulatory compliance. 503B facilities must meet strict FDA standards and follow Current Good Manufacturing Practices (cGMP), ensuring consistent quality that may surpass what in-house operations can achieve.

"By abiding by these laws and meeting these strict standards, hospitals and surgical centers that work with FDA-approved 503B outsourcers are providing the highest level of safe, high-quality preparations for their patients." - Wells Pharma

Cost savings are another big plus. Thanks to their large-scale production capabilities, 503B facilities often offer medications at competitive prices. Outsourcing also helps address staffing shortages, especially considering the 21% turnover rate among pharmacy technicians last year.

Additionally, outsourcing provides flexibility and better access to medications. 503B facilities can produce drugs in bulk, including those in short supply or not commercially available. Unlike 503A pharmacies, which are generally limited to in-state sales, 503B facilities can serve customers nationwide, ensuring broader availability. However, these benefits come with certain risks.

Risks of Outsourcing

While outsourcing offers many advantages, it also comes with challenges that healthcare organizations must carefully evaluate. Quality control is a major concern. Past FDA surveys have highlighted alarming issues with compounded medications, emphasizing the importance of rigorous vendor assessments.

Supply chain reliability is another challenge. Organizations must thoroughly vet potential 503B partners to ensure dependable service. This includes reviewing FDA inspection documents, such as FDA Form 483 citations, which flag problematic conditions.

Compounded drugs also lack the extensive testing required for FDA-approved medications. A 2018 study revealed that 61% of hospitals fell short of USP <797> standards, underscoring the need for careful vendor selection.

To address these risks, facilities should:

  • Conduct detailed vendor evaluations with input from multidisciplinary teams.

  • Confirm FDA registration and compliance with state Board of Pharmacy rules.

  • Set clear quality standards and establish monitoring protocols.

  • Maintain internal expertise to oversee outsourced operations effectively.

"503B Outsourcers have the expertise to know what is required because they have individuals who know what is required by the FDA and state regulatory boards, and possess the ability to provide sterile, compounded drugs to their healthcare clients quickly and at competitive prices." - Wells Pharma

Managing Outsourced Services

Selecting Vendors

Choosing the right outsourcing partner demands careful evaluation. Recent data shows that 75% of facilities outsource some part of their compounded preparations, but only 35% conducted onsite visits to their partners in 2020. This step is directly linked to meeting FDA requirements.

When evaluating vendors, a consistent process should focus on key areas:

Assessment Area

Key Evaluation Points

Regulatory Compliance

FDA registration, state licenses, inspection history

Quality Standards

USP <797> compliance, environmental monitoring, sterilization methods

Operational Capabilities

Production capacity, delivery systems, emergency protocols

Quality Control

Testing procedures, documentation systems, recall protocols

"The pharmacist in charge or physician who is purchasing outsourced compounded preparations is legally responsible for the quality and safety of the purchased compounded preparations."

Setting Quality Standards

After selecting a vendor, it's important to define clear quality benchmarks. By 2022, 71% of healthcare facilities had established their own vendor selection guidelines. These benchmarks should include:

  • Adherence to current Good Manufacturing Practice (cGMP) standards

  • Regular environmental monitoring with proper documentation

  • Clear protocols for reporting adverse events

  • Comprehensive quality assurance programs

  • Detailed documentation of all processes

Monitoring Performance

Once quality standards are in place, tracking performance is essential. This can be achieved through:

  • Scheduled site visits, both announced and unannounced, to assess key metrics

  • Reviewing documentation such as FDA inspection reports and monitoring data

  • Establishing open communication channels to address issues quickly

Regular monitoring ensures that vendors meet expectations and helps maintain compliance.

Keeping Internal Knowledge

Retaining in-house expertise is crucial for effective oversight and achieving quality and cost goals. Key practices include:

  • Providing ongoing internal training on vendor management

  • Involving key staff in oversight activities

  • Preparing contingency plans for potential service interruptions

  • Regularly updating internal procedures

  • Documenting all vendor management processes

This approach allows pharmacies to manage outsourced services effectively while retaining critical internal capabilities.

Conclusion

When deciding between outsourcing and in-house compounding, pharmacies need to weigh several factors that directly affect their operations and patient care. For instance, only 57% of hospital pharmacies currently meet compounding regulations, and fewer than 25% feel they are fully compliant. This highlights the importance of making an informed and deliberate choice.

Here’s a quick breakdown of the key considerations:

Factor

In-House Consideration

Outsourcing Consideration

Cost Structure

High upfront investment, ongoing facility costs

Predictable expenses, lower infrastructure costs

Compliance
