    Intended Use

    The Jaundice Meter (JM-103) is a non-invasive transcutaneous bilirubinometer. It measures yellowness of subcutaneous tissue in newborn infants and displays a measured value which has been shown to correlate with serum bilirubin. The device is for use in the hospital to assist clinicians in monitoring the status of newborn infants for the development of hyperbilirubinemia. The device is not intended as a standalone for diagnosis of hyperbilirubinemia. It is to be used in conjunction with other clinical signs and laboratory measurements. Newborn infants whose Jaundice Meter (JM 103) test results are indicative of hyperbilirubinemia are evaluated by their doctor(s) for appropriate patient management. Bilirubin levels should be confirmed by other methods, such as serum bilirubin, prior to treatment determinations. This device is not intended for home use. This is a prescription device.

    Device Description

    The JM 103 Jaundice Meter is designed to provide a non-invasive measurement of the yellowness of subcutaneous tissue. This measurement is converted to an estimated bilirubin concentration and displayed in units of mg/dL or umole/L. This measurement is taken using a dual path optical system. The measurements from each path are then subtracted to minimize the impact of skin pigmentation. The software in the device then computes the estimated bilirubin concentration based on an established correlation coefficient.

    Acceptance Criteria and Study for Minolta Hill-Rom Air Shields JM 103 Jaundice Meter

    This document outlines the acceptance criteria for the Minolta Hill-Rom Air Shields JM 103 Jaundice Meter and details the clinical study performed to demonstrate its performance.

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided document does not explicitly state pre-defined acceptance criteria in terms of specific thresholds for correlation coefficient (r) or standard deviation (SD). However, the clinical study's results (correlation and SD) serve as the device's demonstrated performance, indicating what was considered acceptable by the FDA for market clearance. The predicate device (JM 102) itself is the benchmark for "substantial equivalence."

    MetricAcceptance Criteria (Implied by Predicate)Reported Device Performance (Site A Forehead, n=513)Reported Device Performance (Site A Sternum, n=513)Reported Device Performance (Site B Forehead, n=100)Reported Device Performance (Site B Sternum, n=100)
    Correlation Coefficient (r) between JM 103 and Total Serum Bilirubin (TSB)(Not explicitly stated, but expected to be high, similar to predicate)0.9140.9460.840.89
    Standard Deviation (SD) between JM 103 and TSB(Not explicitly stated, but expected to be low)1.291.022.141.85
    Regression Equation Slope(Expected to be close to 1)1.051.071.071.16
    Regression Equation Intercept(Expected to be close to 0)-0.35-0.740.00-0.43

    Note: The acceptance criteria are "implied" because the document focuses on demonstrating correlation and performance, rather than setting a pass/fail threshold. The FDA's clearance indicates that these demonstrated performance metrics were deemed substantially equivalent to the predicate device.

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size:
      • Site A: 513 (for both forehead and sternum measurements per patient, presumably)
      • Site B: 100 (for both forehead and sternum measurements per patient, presumably)
      • Total: 613 patients across two sites.
    • Data Provenance: The study was a prospective clinical assessment performed at two study sites. The specific country of origin is not explicitly stated, but given the manufacturer (Hill-Rom Air Shields, Hatboro, PA) and the FDA submission, it is highly probable the studies were conducted in the United States.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    The document does not provide details on the number of experts or their qualifications for establishing the ground truth. It states that the JM 103 estimated bilirubin concentration was correlated with total serum bilirubin concentration. This indicates that the ground truth was derived from laboratory measurements of total serum bilirubin, which is a standard and objective clinical assay, rather than expert consensus on transcutaneous measurements. Therefore, direct "experts" for ground truth establishment in the traditional sense (e.g., radiologists assessing images) would not be applicable here.

    4. Adjudication Method for the Test Set

    Since the ground truth was established by total serum bilirubin (TSB) laboratory measurements, an adjudication method (like 2+1 or 3+1 for expert review) is not applicable or mentioned. TSB results are quantitative and typically considered definitive for bilirubin levels in this context.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    There is no indication of an MRMC comparative effectiveness study being performed. The study aimed to establish the correlation between the JM 103 device and serum bilirubin, not to compare human reader performance with and without AI assistance. The JM 103 is a measurement device, not an AI-assisted diagnostic tool that aids human interpretation.

    6. Standalone (Algorithm Only) Performance Study

    Yes, a standalone performance study was done. The clinical assessment directly demonstrates the performance of the JM 103 device (algorithm only, as it's a physical device with embedded software) in correlating its transcutaneous bilirubin measurements with total serum bilirubin (ground truth). The reported "r" and "SD" values represent this standalone performance. The device is intended to assist clinicians, but its correlation and accuracy are assessed independently of human interpretation of its raw output.

    7. Type of Ground Truth Used

    The type of ground truth used was laboratory measurements of Total Serum Bilirubin (TSB). This is a direct, objective biochemical measurement of bilirubin concentration in the blood, considered the clinical standard for establishing bilirubin levels.

    8. Sample Size for the Training Set

    The document does not specify a separate training set or its sample size. The clinical assessment described appears to be the primary dataset used to demonstrate the device's performance and correlation. It's possible the "established correlation coefficient" mentioned in the device description refers to internal data or previous models (e.g., from the JM 102), but this is not detailed. The provided study focuses on validation/performance assessment of the device as a whole. Without a clear indication of a distinct training phase/set, it's assumed the device's underlying algorithm was potentially developed using other data, but the performance reported relates to the final product on the described clinical study population.

    9. How the Ground Truth for the Training Set Was Established

    As a separate "training set" is not explicitly mentioned or detailed, the method for establishing its ground truth cannot be determined from the provided text. If the "established correlation coefficient" refers to the model built into the device, it would likely have been established through a similar process of correlating transcutaneous measurements with laboratory-confirmed total serum bilirubin (TSB).

    Intended Use

    The Versalet 7700 Care Center is a mobile, caster mounted, neonatal device, which is used to assist in maintaining an infant's skin temperature and thermal environment. The device accomplishes this using radiant and convective heat. Accessories and options to the device permit environmental control and monitoring including humidification. It is intended for inpatient use in maternity nurseries, and neonatal care environments of hospitals or other healthcare facilities.

    Device Description

    The Versalet™ 7700 Care Center is a warming device that combines the heating technologies of both incubators and radiant warmers into one product. The Versalet™ 7700 Care Center provides thermal isolation primarily through a convective air system with canopies and side panels to form an enclosure that isolates the air surrounding the infant from the room air. The Versalet™ 7700 Care Center offers access to the infant by allowing the caregiver to open port holes, side panels, canopies, and, if more access is needed, raising up of the over head arm. The over head arm is the upper half of the infant enclosure containing the canopies. The over head arm can be is raised to obtain full access to the infant. The over head arm contains two Calrod (Magnesium oxide encased in Incoloy sheath) heaters that provide heat when the canopies are opened or the over head arm is raised.

    In addition to providing thermal support, the Versalet™ 7700 Care Center is capable of controlling options and accessories to aid the caregiver in rendering care to the infant. A humidification accessory is designed to operate with the Versalet™ 7700 Care Center.
