Cumulative sum control charts for admixture quality control

R L Sanford

    American Journal of Hospital Pharmacy
    |May 1, 1980
    PubMed
    Summary

    Cumulative sum control charts effectively monitor the sterility of intravenous admixtures. These charts allow for adaptable sampling frequencies to detect quality shifts, balancing cost and benefit for improved production.

    Area of Science:

    • Quality control in pharmaceutical manufacturing
    • Sterility assurance in healthcare settings

    Background:

    • Centralized services for intravenous (i.v.) admixtures require robust quality monitoring.
    • Traditional control charts may not be optimal for detecting subtle shifts in sterility.

    Purpose of the Study:

    • To discuss the application of cumulative sum (CUSUM) control charts for monitoring i.v. admixture sterility.
    • To highlight the flexibility and cost-benefit analysis enabled by CUSUM charts.

    Main Methods:

    • Establishing acceptable and rejectable quality levels for chart creation.
    • Varying sampling frequencies to optimize detection of quality deviations.
    • Implementing CUSUM charts for continuous process monitoring.

    Main Results:

    • CUSUM charts provide a data-driven basis for action regarding existing product quality.
    • The charts enhance the ability to maintain and improve future product quality.
    • Sampling frequency directly influences the sensitivity and speed of detecting unacceptable shifts.

    Conclusions:

    • Cumulative sum control charts are a valuable tool for ensuring the sterility of i.v. admixtures.
    • The adaptable nature of CUSUM charts allows for efficient quality management on a cost-benefit basis.
    • Effective implementation supports both immediate corrective actions and long-term quality improvement.
