The Importance Of Medical Safety

The risk management of a product does not end once a product is on the market -- in fact, it becomes more rigorous. The work that Medical Safety does in post market surveillance and vigilance are integral in ensuring marketed products perform as intended and do not harm patients. ISO 14971 provides guidance on what should be included in a post-market monitoring process:
• Determination if changes must be made to the original medical device risk assessment;
• A systematic process to evaluate product (not just customer complaints);
• Inclusion of objective evidence in the risk management file;
• Evaluation of any new hazards;
• Determining whether there have been changes in the acceptability of risks as originally defined; and
• Inclusion of …show more content…

The information gathered provides insight to what product was involved, where the event occur, what harm resulted from the event, the severity of the harm, what treatment was given, and what outcome resulted.
The challenge of post market complaint data is the variability of information received. Some reporters provide detailed information on the complaint and treatment (e.g., a central 1mm corneal ulcer with negative cultures treated with Vigamox® every hour in affected eye) while other complaints may be vague (e.g., eye pain). Medical Safety is tasked with case follow up to ensure all pertinent information is gathered. The timeliness of complaint report processing and the quality and accuracy of complaint reports are critical in the analysis of post market …show more content…

To ensure consistency of medical assessments, Medical Safety decides and establishes the criteria of a complaint. This is needed because there are varying treatment and risk profiles within a medical diagnosis. For example, a report of Endophthalmitis is a serious event. However, how is the severity of a bacterial infection established? A bacterial infection of the central cornea with a positive culture for pseudomonas has a higher severity than a bacterial infection of the conjunctiva with no corneal involvement. By having a criterion, Medical Safety accurately and consistently classifies complaints. The criterion helps with the assessment of cases with limited information. For example, reports of “chemical burn” would be considered more serious than a report of “irritation”. By establishing an adverse event reporting criteria, Medical Safety effectively assesses complaints in a consistent fashion. This increases the reliability of complaint trending and analysis and helps Medical Safety to monitor a products safety profile.
At set time intervals, Medical Safety compares post market complaints and sales to identify trends in complaint reporting and unexpected product event combinations. Medical Safety does this by using statistical and descriptive analysis. Three examples of signaling and trending methods that can be used include: Empirical Bayes Geometric Mean (EBGM), U-Chart,
