The Crit-Line Anemia Management software is a database application used to record, track and trend patient data as pertains to the management of anemia, and provide a dosage recommendation.
The CLAM software is a database application that records, tracks, trends, and analyzes patient data (Hematocrit, Oxygen Saturation, and Hemoglobin) along with current ESA dose in order to effectively manage anemia. During dialysis treatment, the CLAM downloads initial, real-time Hematocrit (HCT), Oxygen Saturation (SaO2), and Hemoglobin (Hb) data from the Crit Line blood monitor. The CLAM software trends this patient data along with current Erythropoiesis Stimulating Agent (ESA) dosage to determine the patient's Hb levels, the need (if any) for ESA dosing, and to track patient's response to treatment. The CLAM software uses a proprietary algorithm to calculate a recommendation for ESA dosage based on patient data trends and current ESA dose in order to establish and maintain predetermined patient Hb levels. The CLAM proprietary algorithm used to determine ESA dosing for anemia treatment is based on the current manual algorithm. In addition, the CLAM software generates and prints patient reports for review and record keeping. The CLAM software resides on a host computer separate from the Crit Line units and acquires real-time data from the clinic's Crit Line monitors via wireless radio signal or by a serial cable.
Here's an analysis of the provided text regarding the acceptance criteria and study for the Crit Line Anemia Management (CLAM) software:
The provided 510(k) summary focuses primarily on establishing substantial equivalence to predicate devices and describes a performance comparison of its ESA dosage recommendation algorithm to manual calculations. It does not provide explicit "acceptance criteria" in the typical quantitative sense (e.g., target specificity, sensitivity, or accuracy thresholds) for the device's performance, nor does it conduct a comprehensive clinical study to prove these against a definitive ground truth. Instead, the study aims to show agreement with current manual practice.
However, based on the information provided, we can infer the implicit "acceptance criteria" as the calculated ESA dosage recommendation being "exactly the same" as manually calculated doses.
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| CLAM software calculated recommended ESA dose = Manually calculated ESA dose | The CLAM software calculated recommended dose and the manually calculated dose were exactly the same. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: 62 dialysis patients
- Data Provenance:
- Country of Origin: New England (United States, as per typical use of "New England" in this context)
- Retrospective or Prospective: Retrospective data using "the last two weeks of a patient's Hb values" being recorded for analysis.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- The ground truth was established by "manually calculated ESA dosage calculations," implying that medical personnel (e.g., clinicians, nurses, physicians as described in Intended User Population) performed these calculations.
- The document does not specify the number of experts, their specific roles (e.g., physician, nurse), or their qualifications (e.g., years of experience).
4. Adjudication Method for the Test Set
- The document does not describe an adjudication method. The comparison was directly between the CLAM software's calculation and the "manually calculated dose," which presumably represents the established practice. There's no mention of a consensus process among multiple manual calculators or a tie-breaking mechanism.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and If So, What Was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
- No, an MRMC comparative effectiveness study was not explicitly done. The study's focus was on the agreement between the CLAM software's recommendation and manual calculations, not on comparing human reader performance with and without AI assistance or quantifying an "effect size" of improvement.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Yes, a standalone performance evaluation was done. The "performance test" directly compared the CLAM software's calculated ESA dosage recommendations (algorithm only) to manually calculated recommendations. The CLAM software generated its recommendation based on inputted patient data (Hb values and current ESA dose), independently of human input for that specific calculation step.
7. The Type of Ground Truth Used
- Expert Consensus / Expert Determination (via manual calculation): The ground truth for this specific performance test was the "manually calculated ESA dosage calculations." This represents a determination made by medical professionals based on established protocols. It is not pathology, imaging, or direct outcomes data, but rather a calculation based on clinical parameters and existing practice.
8. The Sample Size for the Training Set
- The document does not explicitly state the sample size used for training the CLAM software's proprietary algorithm. It mentions the algorithm is "based on the current manual algorithm" but provides no details on how it was developed or trained on specific datasets.
9. How the Ground Truth for the Training Set Was Established
- The document does not specify how ground truth for any potential training set was established. It states the CLAM algorithm "is based on the current manual algorithm," which implies that the logic and principles of existing manual ESA dosing protocols formed the basis of the algorithm's design. It does not detail if or how a separate, labeled dataset with established ground truth was used to train or refine the algorithm.

The CLAM software is a database application that records, tracks, trends, and analyzes patient data (Hematocrit, Oxygen Saturation, and Hemoglobin) along with current ESA dose in order to effectively manage anemia.
During dialysis treatment, the CLAM downloads initial, real-time Hematocrit (HCT), Oxygen Saturation (SaO2), and Hemoglobin (Hb) data from the Crit Line blood monitor. The CLAM software trends this patient data along with current Erythropoiesis Stimulating Agent (ESA) dosage to determine the patient's Hb levels, the need (if any) for ESA dosing, and to track patient's response to treatment. The CLAM software uses a proprietary algorithm to calculate a recommendation for ESA dosage based on patient data trends and current ESA dose in order to establish and maintain predetermined patient Hb levels. The The CLAM proprietary algorithm used to determine ESA dosing for anemia treatment is based on the current manual algorithm. In addition, the CLAM software generates and prints patient reports for review and record keeping.
The CLAM software resides on a host computer separate from the Crit Line units and acquires real-time data from the clinic's Crit Line monitors via wireless radio signal or by a serial cable.
A. Crit Line IIITQA Blood Volume Monitor and CLAM Accessory
The Crit Line uses optical methods to measure HCT, SaO2, and then calculates Hb from HCT for patients undergoing hemodialysis treatment. The Crit Line system consists of a blood monitor, optical clip and blood chamber.
{2}------------------------------------------------
Image /page/2/Picture/0 description: The image contains the text "HEMA METRICS" in a bold, sans-serif font. The word "HEMA" is positioned above the word "METRICS". A curved line spans from below the left side of "HEMA" to above the right side of "METRICS", visually connecting the two words. The letters "TM" are in superscript to the right of the word "METRICS".
The blood chamber is attached to the dialysis tubing prior to treatment and the optical clip is clipped to the blood chamber, allowing optical access to the blood flow. The Crit Line monitor collects baseline (pre-treatment) readings of HCT, SaO2, and Hb levels and subsequent ongoing readings during treatment. When Crit Line units are used with the CLAM software accessory, baseline readings are transferred to the CLAM application, which establishes a baseline and subsequently performs near real-time monitoring as described above.
B. Intended Patient Population
The CLAM software currently is intended for use in dialysis clinics which care for adult renal failure patients :(see Section 21 - Other for the study: "Use of 12x/month haemoglobin monitoring with a computer algorithm reduces haemoglobin variability").
C. Intended User Population and Use Environment
The CLAM software is intended for use by medical personnel such as clinicians, nurses, and physicians in dialysis clinics or where ever dialysis treatment is provided and/or Crit Line is used.
D. CLAM Software User Interface
The CLAM software interface is designed to centralize and automate many of the routine tasks performed by medical staff when collecting and handling patient data used in the management of anemia. Features of the CLAM software enables the user to collect, record, track, trend, report, analyze, and print data for review and record keeping. An additional feature of the CLAM software is the ability to calculate a recommended ESA dosage based on trending of patient Hb and current ESA dose.

C. Performance Data
A performance test was completed in September of 2009 at a dialysis center in New England where the CLAM software ESA dosage calculations were compared to ESA dosage calculations performed manually.
The test consisted of taking data from sixty-two dialysis patients for analysis. The last two weeks of a patient's Hb values were recorded and the average of Week 1 was subtracted from the average of Week 2. If the difference between the two weeks is positive then the trend is falling, and if the difference was negative the trend was rising. The average of Week 1, the absolute value of the difference, and the rising or falling trend is then used to derive the next recommended dose. The results showed that the CLAM software calculated recommended dose and the manually calculated dose were exactly the same.

HEMA METRICS ...
D. Conclusion
The CLAM software is designed to work in tandem with the predicate device (Crit Line) to provide a more comprehensive and accurate approach to managing anemia treatment following hemodialysis.
The Crit Line uses an optical method to measure HCT and SaO2 and then calculate Hb from HCT for patients undergoing hemodialysis. Crit Line takes a baseline reading just prior to the start of hemodialysis and then continues to take measurements during the duration of treatment. Upon completion of the hemodialysis run the CLAM software downloads these baseline readings to the CLAM database where it is stored for tracking and trending.
The current protocol used by most clinics to assess Hb levels in a dialysis patient is to draw blood one time per month from which the physician prescribes (if needed) ESA dosage for the following month or until the next blood draw. This method provides little data and does not account for the time and changes experienced by the patient between blood draws. One change experienced by the patient is the removal of excess fluid during hemodialysis. On average a dialysis patient will underqo ten to twelve dialysis treatments between the once a month blood draw. The changes to HCT in relation to total blood volume are changed with each hemodialysis treatment affecting Hb levels as well.
The CLAM software provides the means to record, track, and trend these critical changes along with current ESA dose with each hemodialysis treatment. This method provides up to twelve points of data per month to measure patient status compared to the one point currently used. Based on trending of Hb levels and current ESA dose the CLAM software gives an ESA dosage recommendation for the physician's consideration.
The CLAM software device, like the Crit Line monitor, is for use only under supervision of a healthcare provider and is not intended to replace the knowledge and experience of the healthcare provider when prescribing treatment
Additional safeguards are incorporated in the CLAM software interface and algorithm to mitigate or prevent harm to the patient by limiting the maximum dosage recommendation of the CLAM software to 20,000 IU per treatment, to flag those patients whose Hb levels fall outside the established limits, and to prevent interchange of Hb and HCT values when entered manually.
In conclusion, the CLAM software like the predicate devices is designed to record, track, and trend patient data for the purpose of providing accurate readings, ongoing analyses of patient data, and as a reference for physicians when determining an effective course of treatment. For these reasons the CLAM software is considered equivalent to the predicate devices and does not pose any additional safety or effectiveness issues.
