    Hi,

    Can you advise on the actions necessary if the calibration meter which was used for calibrating medical devices is found to be faulty . There was no injury caused but could have had the potential to cause one.

    I infer you market your medical device is the US, so I've confined my response to that system. Other geographic regions could have different answer.

    Under 820.72(b), "evaluate whether there was any adverse effect on the device's quality". You didn't describe the type of failure, but the most common problem is bias in the instrument's reading that causes you classify nonconforming product as conforming based on the measurement. This is the adverse effect.

    If so, take two actions. Correction brings the instrument back into a functional state. Corrective action, determines the cause of the nonconformance and eliminates. Be sure to follow the corrective action process in 820.100.

    Under 803.50(a)(2) file a medical device report, MDR, if the device malfunctioned and would be likely to cause or contribute to a death or serious injury, if the malfunction were to recur. Malfunction means the failure of a device to meet its performance specifications or otherwise perform as intended. I think this situation meets the definition of a malfunction.

    Be sure to create an MDR Event File under 803.18 and c complaint under 820.198. I often see people argue that a complaint requires a report from a customer, but this is not true. You can create a complaint based on internal actions as long as the device had been released for distribution.

    I recommend that you file the MDR. I'm very conservative about these things. I've never seen a Warning Letter for submitting too many MDRs, but there are many for too few.

    In addition to what Dan suggests, in your corrective action process you need to consider a possible recall of any devices that were "calibrated" using the out of calibration device. Any time you encounter such a situation you need to look back at all devices released since the last known good (calibration) of the measuring device in considering your corrective action. This is why many companies do daily (or more frequent) calibration checks on any measurement device that impacts release of the product.

    Dan said "I recommend that you file the MDR. I'm very conservative about these things. I've never seen a Warning Letter for submitting too many MDRs, but there are many for too few."

    I used to feel this way as well, and at one time it was no doubt true - the biggest risk to MDR filing was your competitors would use them against you. However, having now been through two different situations of FDA using their "early signal detection process" in which the entire signal was "there seem to be a lot of MDRs," I have changed my thinking. In both these cases, the situation took years to resolve and the impact to the business was enormous, given that HOSPITALS think that FDA has actual facts when they send out notices, and in no way to they differentiate from "early signals" and "full blown safety notices."

    Thus, while I am still a stickler for filing MDRs in situations where the definition is met, I am much less bullish on filing for complete grey areas (such as when I can think up a crazy scenario where an injury could occur but never has). I am not entirely sure we have enough info from the original poster to know if they need an MDR or not, but I totally agree it is one of the things that must be assessed as they work through the process.

    We probably need more information to advise. Was this a calibration tool shipped with a specific device (or devices) that is routinely used before using the device? or are you asking about a calibration tool in your production line, potentially impacting all devices that came off that manufacturing line over some time period?

    In either case, if it can cause an injury or adverse event, it would seem that some kind of field correction or recall would be needed - the specifics will depend on the exact situation.

    Hi,

    Thanks all, for your feedback provided to my query. To Ginger's question , this was a calibration meter used for servicing. So yes , there are many devices that were calibrated with this meter , however we heard of only one incident , but there was no adverse event. Basically our device operations are based on professional judgement , so any experienced user will not go ahead once he feels something is not right.
