Abstract:
Marketed drugs and devices possess specifications including critical microbiological quality attributes purposed to assure efficacy and patient safety. These attributes are legislated requirements intended to protect the recipient patient. Sampling, microbiological testing, interpretation of data for final products, raw materials, and intermediates all contribute to a cohesive assessment in the assurance of finished product quality. Traditional culture-based microbiological methods possess inherent and unavoidable variability, recognized by the compendia and which might lead to erroneous conclusion pertaining to product quality. Such variability has been associated and intrinsically linked with data integrity issues; manufacturers have subsequently been encouraged by regulatory authorities to introduce multiple microbiologists or checks to prevent such issues. Understanding microbiological variability is essential such that genuine data integrity issues are identified. Furthermore, a range of meaningful preventative strategies are feasible beyond increasing the capacity of the quality control microbiological laboratory. This short review describes the legislative requirements, inherent microbiological variability, and realistic actions and activities that genuinely assure patient safety.LAY ABSTRACT: Marketed drugs and devices possess specifications including critical microbiological quality attributes purposed to assure efficacy and patient safety.
