- Description
- This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR 12.6 as supplemented with additional information included in this notice. This announcement constitutes the only solicitation and a separate written solicitation will not be issued. This solicitation number is NIH-NIDDK-04-314, and is issued as a Request for Quotation (RFQ). The solicitation/contract will include all applicable provisions and clauses in effect through Federal Acquisition Circular 2001-23. The North American Industry Classification (NAICS) Code is 561990 and the business size standard is $6.0. However, this solicitation is not set aside for small business. This acquisition is being conducted using Simplified Acquisition Procedures in accordance with FAR Part 13. The National Institutes of Health (NIH), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), has a requirement for ECG Interpretation. Tasks to be performed: Code backlog of unread EDGs using the Minnesota Code Technical requirements: 1) The ECG reading center shall read ECGs following the methods and criteria of the Minnesota Code, according to the rules in the Minnesota Code Manual of Electrocardiographic Findings. 2) ECG Reading Procedures: The NIH will provide electronic or paper copies of the ECGs to the reading center. Earlier ECGs are only available on paper. Contractor shall specify the type of electronic files they accept. 3) Measurements: The following measurements are required. Specific methods for making the measurements shall be at the discretion of the Contractor and must be described in detail in their proposal. Differences from the methods described below shall be justified in their proposal. Heart Rate: Use a metric rule to measure 5 RR intervals in mm from the middle of the ECG hard copy, then get corresponding heart rate from a Look-up Table for Heart rate and QT rate correction coefficient. P-R Interval: The P-R interval should typically be read from lead II. 1) To determine the onset of the P-wave find the point underneath the baseline where the rise begins to form the P-wave (A); from that point project a vertical line upward to the point where the line crosses the top of the baseline (B); B is the beginning of the P-wave. 2) In case of an initial R-wave, the beginning of QRS is measured from the lower edge of the baseline; when the QRS pattern is a QS-wave, onset is measured at the upper edge of the baseline; when the QRS begins with a Q, its onset is measured from the upper edge of the baseline. Q-Wave: 1) Q-wave amplitude will be measured vertically from the onset of the QRS at the lower margin of the baseline to nadir. 2) QS-wave amplitude will be measured vertically from the onset of the QRS at lower margin of the baseline to nadir. 3) Q-wave duration is measured on the top of the baseline from the beginning of the Q to where the Q intersects the scale. If a stepped shoulder precedes the steeper descend of the Q-wave, it is included in the measurement of the Q-wave. R-wave amplitude is measured vertically from the onset of the QRS at the upper margin of the preceding PR baseline to the peak of the R. QRS axis: 1) measurements are taken on the next to last complete normal beat in leads, I, II and III defined as that normal beat which immediately precedes the last normal codable beat. If there are only two beats in a lead, the measurements should be taken on the last complete normal beat. 2) To determine the amplitude of the main positive wave (whether R or R?), measure from the upper baseline margin at the onset of QRS to the peak of the R- or R?- wave. For the amplitude of negative waves, measure from the lower margin of the baseline at QRS onset to the nadir of the largest wave. R? is a second R-wave. 3) Measurements of positive or negative waves are rounded up to the nearest 0.25mm. 4) If the sum of the positive and negative waves is not a whole number, it should be rounded up to the nearest 0.5mm. QRS duration: (1) QRS duration in Lead II only; or (2) Maximum QRS duration from records with simultaneous 12 lead recording, usually take measurement at Lead V2-V5. J-point: 1) The amplitude of J-point depression is measured vertically to the intersection of a tangent drawn horizontally from the upper margin of the PR baseline at the onset of the QRS. J-point depression is measured in mm. The reference for determining J-point displacement is the upper margin of the baseline immediately preceding the QRS complex. 2) If a break in the curve between QRS and ST segment can be seen, but the exact point is indeterminate, a tangent is drawn along the straightest section to be found (one at least 2 mm in length) of the lower margin of the ST segment at the beginning of ST. The J-point is on the upper margin opposite the point the tangent and the ECG separate. 3) Where there is not straight part of the ST segment at least 2 mm long for constructing a tangent, a truly curved ST segment exists and no J-point is measured. 4) When two separate breaks in the curve at the end of the QRS are observed, take the second or rightward point to determine the J-point for 4-codes. 5) When the S-wave continues in a smooth curve to the peak of the T-wave, the end of the QRS is determined from where a horizontal tangent from the upper margin of the baseline at the beginning of the previous QRS complex intersects the upward curve. 6) When the end of the ST segment merges with the T-wave, the ST segment is considered to extend to the peak of the T-wave. 7) When a near-perfect curve is present (no straight ST segment for at least 2 mm) there is no clearly defined ST segment. With this type of ST-T there is no measurable J-point. ST segment: 1) The ST slope is measured from the J-point to the start of the T-wave or to the peak of the T-wave. 2) The direction of the ST segment is classified as horizontal, downward or upward sloping based on the following rule: the segment is not horizontal or downward sloping if any part of it slopes upward. This also applies to curved or U-shaped ST segment. 3) If the amplitude at the end of the ST segment is lower than the J-point, this convex pattern is considered equivalent to a downward sloping ST segment and is so coded. 4) Leads a VR and II are ignored in coding ST segment and T-wave. T-wave: 1) The degree of negativity is measured from the bottom of the ensuing TP interval. 2) To measure a negative T-wave, find the flattest segment of the baseline in the following TP interval. Measure from this point on the lower margin of the baseline vertically to the point that intersects a horizontal line extended from the lower margin of the T-wave nadir. 3) The negative T-wave amplitude is always measured in mm. 4) The negative T-wave amplitude in a diphasic T-wave is measured from the level part of the TP interval at its lower margin. 5) When a rapid heart rate causes the T-wave to fall on the following P-wave, use the previous PR interval as the reference point for measuring positive T-waves. QT duration: (1) QT duration in Lead II only; or (2) Maximum QT duration from 12 Leads, most from lead V2 ? V4 or AVR. Q.R.S Amplitudes for high voltage identification. Basic measurement is R amplitude in Lead AVL and S/QS amplitude in lead V3. 4) Provide detailed description of ongoing internal quality control procedures. Receivables 1) Monthly record of the number, identify, and coding results of coded ECGs for the previous month. This should be provided in an acceptable electronic format ? Excel spreadsheet or SAS dataset. 2) Monthly invoice for payment of coded ECGs. 3) Quarterly report of internal quality control results.
