Congratulations Rachel!

 

 

Thank you, Dr. Fred Grover!

More than 15 years ago, Dr. Fred Grover was appointed to The Society of Thoracic Surgeons (STS) National Database Committee to provide guidance and leadership to the activities of the STS National Database program. Within five years Dr. Grover was appointed Chair of

the committee and has served in that capacity for almost 10 years. Under Dr. Grover's leadership, the successful National Database program has become what it is today: the largest cardiothoracic surgery outcomes and quality improvement program in the world.

To date, more than 620 sites in the United States and Canada participate in the Adult Cardiac Surgical Database. The STS now offers interested participants the opportunity to collect and submit data in the areas of Congenital Heart Surgery and General Thoracic Surgery. Additional staff members in the Chicago office have helped improve communication with site representatives. Clinical questions, data interpretation, contract and payment issues are answered in a timely fashion. Also, the annual Data Managers Meeting provides STS National Database participants with valuable information to assist in the proper collection of data. These popular meetings also highlight the importance of quality improvement and (ultimately) improved care to the cardiovascular patient.

In addition, data quality standards were implemented to improve the local sites' data. More than seven years ago, Dr. Grover led a search committee to find a new data warehouse and analytical center. This search identified the Duke Clinical Research Institute (DCRI) as the warehouse and analytical center for the STS. Significant improvement has occurred in the outcome reports that are sent to participating sites, and there has been improved model development and publication of papers at major meetings and peer-reviewed journals through use of data in the STS National Database.

Currently, Dr. Grover is the Chair of the Department of Surgery at the University of Colorado Health Sciences Center. He was recruited to Denver in September of 1991, as Professor and Head of the Division of Cardiothoracic Surgery at the University of Colorado Health Sciences Center, Chief of Surgical Services at the Denver Veterans Affairs Medical Center, and as Surgical Director of the Lung Transplant Program.

Dr. Grover's interest in quality and outcomes is not limited to the STS. He chairs the National Cardiac Surgery Consultants Committee for the Department of Veterans Affairs and in that capacity helped organize the VA Risk Adjusted Cardiac Surgical Database. Dr. Grover currently chairs a National VA Cooperative Study comparing off-pump coronary artery bypass to on-pump coronary artery bypass. He is Past President of the Southern Thoracic Surgical Association, and was recently elected Second Vice President of the STS. It is with this appointment that Dr. Grover has "handed off" his Chair position of the Workforce on National Databases to Dr. Fred Edwards of the University of Florida in Jacksonville.

Dr. Grover has raised the level of recognition and importance of the STS National Database and through his efforts the program has become the "gold standard" for outcomes reporting and quality improvement. Thank you, Dr. Grover, for giving your time and sharing your passion for quality and outcomes with the STS National Database. We wish you well as you take on new and exciting responsibilities within the STS.



Important Notice: Adult Cardiac Surgery Database, Version 2.52.1

In mid-April 2004, all Adult Cardiac Database active and pending Primary and Data File Contacts received an e-mail message stating that the Adult Cardiac Database, version 2.52 underwent minor modifications. Due to these modifications, please download and use the version 2.52.1 documents listed below. These documents will explain the changes made to both the data and software specifications changes for version 2.52.1.

To guarantee and ensure consistent collection of data, version 2.52 documents should be destroyed. Fortunately, the incorporated changes do not require sites to change data that have already been collected. Mandatory start date for version 2.52.1 is July 1, 2004.

    Adult Cardiac Surgery Database Vendor Software Certification

    The process of certifying vendor software for the collection of version 2.52.1 of the Adult Cardiac Surgery Database is well underway! This rigorous process will help ensure that vendor software collects data correctly and is able to extract data appropriately for submission to the Duke Clinical Research Institute.

    The Society of Thoracic Surgeons (STS) has entered into a contract with Digital Innovations (DI) to perform the certification testing. The certification process begins when DI receives a copy of the vendor's software. The testing process will include steps to ensure that:

    • valid data can be entered into each field.
    • each field rejects invalid data.
    • the parent/child relationships between fields are maintained.
    • all required reporting and querying capabilities exist in the software.
    • records with either data version 2.41 or 2.52.1 can be appropriately created and edited.

    All vendors should complete the certification process by July 1, 2004. Please contact your vendor directly to learn when the upgraded software will be available. Regardless of when vendor software is ready for installation at the site level, the mandatory start date for version 2.52.1 is July 1, 2004. If vendor software is not installed at the site level by this date, sites must begin or continue to collect version 2.52.1 on paper.

    Sites can monitor vendor completion of the certification process by following these directions:

    • Visit the STS Web site: www.sts.org.
    • Select "Database" from the left ORANGE tool bar menu.
    • Select "Data Managers' Section" from the right BLUE tool bar menu.

    General Thoracic Surgery Database: Update

    First Harvest and Report:

    With the mailing of the first General Thoracic Surgery Database (GTDB) Report on March 8, 2004, it is official…the first GTDB harvest has been completed and the GTDB is now on its way to the big leagues to join the Adult Cardiac Surgery Database and the Congenital Heart Surgery Database.

    Eighteen of the 37 active GTDB sites contributed to the fall 2003 GTDB Harvest. The harvest captured 19,924 patients with 20,575 operations and reflects data from 1998-2002. All harvested records were captured using version 1.3 Data Specifications. Also included with the GTDB report was a cd, pdf version of the report. An Executive Summary of the fall 2003 GTDB Harvest can be viewed on the STS Web site: http://www.ctsnet.org/file/2003GeneralThoracicExecutiveSummary.pdf.
    The next GTDB harvest is tentatively scheduled for late October 2004.

    Conversion to version 2.06:

    In early 2004 the STS released version 2.06 of the GTDB and requirements to ensure a proper and consistent upgrade to version 2.06. In February of 2004, software designer Bill Begg began the process of converting the software of active GTDB sites from version 1.3 to version 2.06. Because version 1.3 records must be entered into 1.3 software, sites were encouraged to enter all of their version 1.3 records into version 1.3 software as quickly as possible, or before March 15, 2004. Conversion to version 2.06 could not take place at individual sites until all of the sites' 1.3 records were entered into version 1.3 software. To make a clean break from version 1.3 as of February 1, 2004, sites were instructed to collect all new cases on paper using version 2.06. Upon conversion of software to version 2.06, sites entered 2.06 cases collected on paper into their version 2.06 software. If your active GTDB site needs to be converted to 2.06 software, please contact Bill Begg at bbegg@tsda.org. Currently, new sites that participate in the GTDB will automatically receive version 2.06 software.

    GTDB Volunteer Support:

    As you may know, the Adult Cardiac Database (ACDB) has had a group of volunteer database participants that are referred to as the "ACDB Core Group." This group has contributed to meeting planning, clinical support, data definitions and other general ACDB issues. With the growth of the GTDB, it was decided that a similar group would be beneficial to the GTDB and its participants. The GTDB Core Group met by conference call for the first time in early April 2004. This Core Group meets monthly and will have the same input into the GTDB as the ACDB Core Group has into their Database.

    Participants were chosen based on their exceptional clinical understanding of general thoracic procedures, their technical understanding of databases, and prior volunteerism with the GTDB.

    GTDB FAQ Document:

    The GTDB Core Group decided to create and support a GTDB FAQ Document. Based on the amount of submitted clinical questions, this FAQ document will be updated three times a year: in April, August and December. Please follow the directions below to view the GTDB FAQ Document:

    • Visit the STS web site: www.sts.org.
    • Select "Database" from the left ORANGE tool bar menu.
    • Select "Data Managers' Section" from the right BLUE tool bar menu.
    • From the list of STS Databases (Adult Cardiac, General Thoracic, Congenital) select "General Thoracic Database."

    GTDB to Open to Commercial Vendors:

    In early 2004, the STS approved the concept of transitioning the GTDB from the current STS Access-based shareware to a database that allows for commercial vendor involvement. Many of the GTDB sites are familiar and accustomed to the advanced, sophisticated software that commercial vendors offer to the Adult Cardiac and Congenital Heart Surgery Databases. The STS supports offering this same level of software to the GTDB through commercial vendors.

    The plan to involve commercial vendors in the GTDB includes:

    • The development of a GTDB Software Vendor Contract similar to the contract used by vendors that supply services for the Adult Cardiac and Congenital Heart Surgery Databases. All current STS certified vendors will be given the opportunity to offer services to our GTDB sites.
    • Notifying GTDB sites that version 2.06 will be the final software upgrade received from the STS.
    • The STS decision to stop support of the Access-based shareware by January 1, 2005. This decision will be reflected in an amended software license and participation agreement.
    • Allowing sites to have the option of continuing to participate in the GTDB using the STS Access based shareware or to use software created by a commercial vendor. Those sites that choose to stay with the STS Access based shareware do so with the understanding that all future upgrades and software changes must be completed by and are the sole responsibility of the site. The STS will no longer offer customer support of the STS Access-based shareware.
    • Understanding that if a site chooses to stay with the STS Access-based shareware, it must continue to fulfill its obligations of participating in the GTDB by harvesting data to the Duke Clinical Research Institute (DCRI) once a year. Harvested data that is not compliant with the current version of software specifications will not be accepted by DCRI.
    • New sites interested in joining the GTDB will be offered the option of collecting their data on paper using version 2.06 until commercial vendor software is available or they can use the STS Access-based shareware with the understanding that as of January 1, 2005 the product will no longer be supported by the STS.
    • Commercial vendor focus is to remain on the Adult Cardiac Database Certification process. All potential sites will be notified upon the availability of commercial vendor software for the GTDB.

    STS members and staff are excited about the progress of the GTDB, and are eager to facilitate its future growth.

    New to the Adult Cardiac Database? This meeting is for you!

    Time Devoted to New Data Managers at the October 2004 Meeting!

    Based on written comments received from the November 2003 Meeting evaluations, The Society of Thoracic Surgeons (STS) will devote time at the October 2004 Meeting for Data Managers who are "new" to the Adult Cardiac (AC) Database.

    Many comments from both seasoned and new AC Data Mangers suggested that time at the Annual Meeting be dedicated to the needs of the new AC Data Manager. Seasoned Data Managers said they did not want to sit through information that was directed toward new Data Managers, while new Data Managers said their needs were not being met.

    The dedicated time for new AC Data Mangers will be allotted at the beginning of the AC Data Managers Meeting to give those new to the process a "jump start" before the rest of the AC meeting begins. Because defining "new Data Manger" could be as difficult as defining "Perioperative MI," all are welcome to attend, including Data Managers from both the Congenital Heart Surgery and General Thoracic Surgery Databases.

    Cardiothoracic Reimbursement: Can You Make a Difference?

    If your practice is like most cardiothoracic surgery practices, then you and your colleagues may have reached an all-time high frustration level with the current payment system. Significant reimbursement cuts from the past few years, coupled with the availability of new technologies and surgical techniques, have created an even more complicated coding and reimbursement system. The introduction of the resource-based relative value system (RBRVS) and the conversion of RBRVS to a fully resource-based system have taken a toll on the specialty with regard to the amount of work, practice expense, and professional liability insurance values over the past several years. The added cost and pressure of compliance and HIPAA issues have also affected the specialty.

    The American Medical Association currently houses the Relative Value System Update Committee (RUC), which plays a vital role in developing the work and practice expense values for the CPT codes. The work and practice expense relative value units (RVU) are two of three payment components included in the RBRVS (professional liability insurance is the third) that determine the payment basis for Medicare and many private payers. The RUC consists of 29 members; the medical specialties represent the majority of the RUC membership.

    Other than new codes, the only opportunity to change a work or practice expense value associated with a code is during a five-year review. Congress is mandated to review the work, practice expense and malpractice RVUs every five years. The last five-year work review was in 2000, and the next one will take place in 2005. The STS is in the process of identifying codes that are valued improperly and should be addressed in the 2005 five-year review. The STS will mine the STS National Database during the next several months for data supporting increases in payment to the cardiothoracic codes. In addition, the STS will seek names of physicians willing to participate in the survey process in April-June of 2005 and cardiothoracic surgery practices that are willing to provide additional data from extended local databases.

    The work-relative value unit takes into account the physician's time, technical skills and physical effort, mental effort and judgment, and psychological stress when adverse outcomes develop. The STS will provide physician survey data, as well as any additional data, to support changes in physician work since the last five-year review. This will include data mined from the STS National Database that support an older, sicker patient population. In addition, the surveys and additional database data will be used to identify changes in ICU care, length of stay, intra-operative time, and post-operative care. The STS National Database provides a distinct advantage in this process for cardiothoracic surgery compared with other surgical specialties because of its comprehensive data.

    Because the system is a relative value based system, the procedure that is being surveyed is compared with an existing procedure to help establish a "relative value." The physician work surveys use the mean pre, intra, and post service work times provided by the survey respondents. If surgeons estimate times that are too low or too high, this will have a negative effect on the resulting relative value units assigned to that procedure. Therefore, it is critical that surgeons consider and indicate in the survey the amount of time they spent on each of the pre, intra, and post operative activities identified when they receive a RUC physician work survey from the STS. It is often beneficial to look at the operative log for a given procedure and use the average time for the procedures performed within the past several months. It is also important to accurately reflect the type, number, and level of post-operative visits associated with a procedure, such as critical care, hospital visits, and office visits provided within the 90-day global period.

    The Data Manager will play a critical role because the surgeons will depend on their Data Manager to assist them in obtaining and providing the most accurate data available. They also rely on Data Managers to help them complete the surveys on time. The accuracy, thoroughness, timeliness, and volume of surveys are critical to making arguments for increases in reimbursement during the five-year review process. If your practice is willing to participate in this process, please send your contact information to Julie Painter at JULIEPAINTER@GRANDSUITES.COM, fax it to 720-946-4816, or call 720-946-4815.


    STS Wisconsin Regional Group Round Up
    Jean C. Sesing, R.N. BSN, CCRN

    On March 16, 2004 The Society of Thoracic Surgeons (STS) National Database Regional Groups had their first scheduled conference call. The purpose of the Regional Group conference call is to provide a forum for all Regional Group primary contacts to discuss their experiences and activities. During the first of what we hope will be many calls, a participant expressed her frustration with the difficulty in forming and maintaining interest in a regional group. I would like to highlight our regional efforts in Wisconsin and emphasize the value of regional meetings.

    The Wisconsin Cardiovascular Data Manager Group (WCDMG) was established November 9, 1994. The first meeting was held at Waukesha Memorial Hospital and, since then, has rotated throughout the state. Our group meets biannually in the spring and fall. In October 2004, we proudly mark our tenth anniversary.

    The Wisconsin group was formed initially to facilitate networking. We discuss strategies for collecting data, obtaining physician input and submitting data successfully. Members will often demonstrate ways to use the data for quality improvement. Most important, we have a professional bond that allows us to vent frustration as well as celebrate triumph, which helps us attain an understanding of our roles, and, ultimately, a higher standard of excellence in what we do.

    After several years we have developed a statement that describes our regional group's intent: "The mission of the WCDMG is to pursue the greatest integrity of data possible for the improvement and development of cardiac services." This mission is achieved by:

    • promoting the quality and efficiency of cardiovascular care in the state of Wisconsin.
    • documenting and analyzing health care outcomes on cardiac patients in conjunction with national recognized criteria.
    • providing data to those parties designated in the Wisconsin Bylaws, to improve and/or change clinical practice.

    We use case studies to ensure a higher level of data integrity. In this process, a volunteer from the group will create a narrative case study from a complex situation that he/she has encountered. Each member then completes a basic collection tool and sends it back to the author, who tabulates and presents the results on a Power Point display, along with pertinent definitions and FAQ's. The case study presentation often generates much discussion and learning. Any remaining questions regarding definitions are then e-mailed to the STS FAQ mailbox for clarification. The STS response to the questions is subsequently shared with all regional group members.

    The WCDMG is currently developing a Web site that will be available in fall of 2004. The Web site will hold valuable information, such as key contacts, the case studies, and more.

    Our next meeting will be held on Wed., Nov. 10, 2004 at Oconomowoc Memorial Hospital. All Data Managers are welcome to attend to learn about the value of these meetings! Please feel free to contact me at 262-928-2621, or jean.sesing@phci.org, for further information and directions.

    As WCDMG prepares to celebrate its 10th anniversary, we remember the words of Abraham Lincoln, "Always bear in mind that your own resolution to succeed is more important than any other."



  • Data Quality Tip 1: The Harvest Verification Form

    Although the Duke Clinical Research Institute (DCRI) has tried to implement an efficient data submission process, the Institute recognizes that some glitches will occur. To help ensure that no data are missed at the site or DCRI, the Harvest Verification Form (HVF) is used to verify the record counts at both locations. Each database has its own specific HVF that meets the needs of the particular database.

    Sites are required to supply to DCRI basic record counts and date range information for the data submitted. This includes minimum and maximum surgery dates, total number of records for each year, and a break down of record counts by a field specific to each database (such as procedure type or patient race). Many of the STS-certified vendors' software packages include a report that will generate these numbers for sites. This information provides sites with a "picture" of the sites' extract file.

    When DCRI receives the file, the same counts are calculated as part of the initial processing. The values calculated at DCRI are sent to sites in the sites' Data Quality Report.

    The best way for sites to determine if data received at DCRI are correct is to compare the values stated in the Data Quality Report with the values submitted by the site in the HVF. The two sets of numbers should match exactly, provided no consistency edits or parent/child edits were performed on the submitted data at DCRI. Values that do not match could indicate a problem either in the extract process, or in the processing at DCRI. In either case, sites should contact their Clinical Data Specialist to determine the best approach to correct the problem.

    Sites that compare their HVF with their Data Quality Report have the best chance of ensuring that the data used to produce their individual report accurately reflect the procedure performed at their facility.


    Data Quality Tip 2: Understanding Consistency Edits

    The consistency edit is a standard rule for editing data at the Duke Clinical Research Institute (DCRI). Consistency edits are performed because the data, as submitted, may not be clinically correct. Edits performed by DCRI during the processing of data will appear in a separate section of the Data Quality Report (DQR). These edits should be reviewed meticulously to assure accuracy.

    Adult CV Surgery Database

    For the Adult Cardiac Surgery Database the consistency edits performed include:

    1. Myocardial Infarction (MI) is set to Yes if Status = Urgent and Urgent Reason (UrgntRsn) = AMI.
    2. Myocardial Infarction (MI) is set to Yes if Status = Emergent and Emergent Reason (EmergRsn) = AEMI.
    3. Angina-Type (AngType) is set to Unstable if Status = Urgent and Urgent Reason (UrgntRsn) = USA.
    4. Prev CV Intervent (PrCVInt) is set to Yes if Prior Card Op Req Bypass-# (PrCBNum) is greater than or equal to 1.
    5. Num Dis Vessels (NumDisV) is set to Double if Left Main Dis>50% (LmainDis) = Yes and NumDisV is None, Single, or missing.
    6. Dist Anast - Art # (DistArt) is set to the sum of IMA Dist Anast # (NumIMADA), Radial Dist Anast # (NumRadDA), and GEPA Dist Anast # (NumGEPDA), if the current value of DistArt is missing or less than that sum.
    7. If Mort - DC Status (MtDCStat) = Dead or Mort - Date (MtDate) = Date of Discharge (DischDt)

    Then Mort - Op Death (MtOpD) is set to Yes.
    If Mort - Op Death (MtOpD) is missing, then XXX
    If Mort - 30d Status (Mt30Stat) = Dead
    or Mort - Date (MtDate) is within 30 days of Date of Surgery (SurgDt)
    Then Mort - Op Death (MtOpD) is set to Yes.

    8. Patient age (Age) - Age is set to the number of months between the date of birth (DOB) and the Surgery Date (SurgDt) divided by 12 if it is not already equal to that value.

    Note: Edits performed at DCRI can affect predicted mortality match rate in the participant-specific DQR.

    An example of a DQR appears below. DQR provide both a general section that identifies the edits performed and an itemized section that identifies the specific records affected. Note: The changes being reported reflect the numeric code change that was performed.

    Example: Number of Diseased Vessels (NumDisV) - the value submitted was 2 and it was changed to 3. This indicates that the actual response to the question Number of Diseased Vessels was corrected from harvest code 2 which is one diseased vessel to harvest code 3 which is two diseased vessels. This was based on the information that Left Main Disease > 50% was coded Yes. By definition in the specifications, this is counted as TWO vessels (LAD and Circumflex). Therefore, Left Main + RCA =a total of three diseased vessels.

    • The Age (AgeDays) value is changed to the number of days between the Date of Birth (DOB) and Surgery Date (SurgDt) as calculated by the warehouse if the original value is missing or contains a value that does not equal the calculated value.
    • The Date of Mortality (MtDate) is set equal to the Date of Discharge (DischDt) if MtDate is missing and DischDt contains a valid value and the Mortality Discharge Status (MtDCStat) = Dead.
    • The Date of Discharge (DischDt) is set equal to the Date of Mortality (MtDate) if DischDt is missing and MtDate contains a valid value and the Mortality Discharge Status (MtDCStat) = Dead.
    • The Mortality Discharge Status (MtDCStat) is set to Dead if the original value is missing and the Date of Admission (AdmitDt), Date of Discharge (DischDt) and Date of Mortality (MtDate) all contain valid values and the MtDate is between the AdmitDt and DischDt.
    • If there is more than one operations record for a given patient for a single admission and the Mortality Discharge Status (MtDCStat) = Dead on any of those records, then the MtDCStat is changed to Dead for any of the other records where MtDCStat is Alive or missing.
    • If there is more than one operations record for a given patient for a single admission and the Mortality 30-Day Status (Mt30Stat) = Dead on any of those records, then the Mt30Stat is changed to Dead for any of the other records where Mt30Stat is Alive or missing.

    An example of a DQR appears below. DQR provide both a general section that identifies the edits performed and an itemized section that identifies the specific records affected.

    Determining the Procedure Type in the Adult Cardiac Surgery Database

    The national reports generated twice a year from the Adult Cardiac Surgery Database focus on the five most frequently performed procedures: Isolated CAB, Isolated Aortic Valve Replacement, Isolated Mitral Valve Replacement, CAB + Aortic Valve Replacement, and CAB + Mitral Valve Replacement. AVR + MVR procedures and all other isolated and combination procedures are grouped together into one "Other" category. But how do you determine which procedure type is assigned to a specific patient? The answer to this question has changed with the introduction of version 2.52.1 of the data specifications.

    Some of the changes in version 2.52.1 affect the fields and values that determine the procedure type. In addition to these changes in variables, the insertion of a Ventricular Assist Device field (the VAD field) will now be included in determining the procedure type. Because of these changes, the data version of the patient record (the DataVrsn field) is now incorporated into the algorithm used to determine the procedure type. Essentially, one method is used for records with data versions 2.35 or 2.41, while another method is used for 2.52.1 records.

    The algorithm for determining the procedure type is provided in Appendix B of the v2.52.1 Software Specifications document that is available on The Society of Thoracic Surgeons (STS) Web site. This one algorithm is designed to be used with data records with any data version value.

    From the STS Web site, you can also download the two versions of the "Procedure Identification Tables," version 2.41 (which should also be used for 2.35 records) and version 2.52.1. These tables describe the values expected in each of the key fields for the procedure to be considered a specific type.

    Many of the vendors providing software for collecting STS data have incorporated the procedure identification algorithm into their software packages to calculate this information for a given record. If your software does not have this feature, you can use the algorithm provided in Appendix B of v2.52.1 Software Specifications and the two procedure identification tables provided on the STS Web site to generate this information.

    Adult Cardiac Surgery Database Harvest Update

    The Spring 2004 Adult Cardiac Surgery Database harvest was a great success! This year, the number of participants increased for the seventh harvest in a row with 508 participants contributing data. Most participants submitted their data multiple times during the harvest, and the data warehouse processed nearly 1,400 data files. The National Database now has more than 2.5 million records with the combined historic and new data. The national analysis reports generated from this harvest will be distributed in early June. Here are a few "fun facts" from the harvest:

    Number of participants submitting for the first time: 32
    Number of records submitted by participants: minimum=16, maximum=6,202, median=371
    Number of times participant submitted a file: minimum=1, maximum=11, median=2
    Average time between receipt of file and delivery of Data Quality Report = 18.2 hours


    Updating your Primary Contacts Information…

    It's that time of year again… flowers are blooming, the sun is shining, warm weather is coming (for those of you who live in the Midwest), and we're now preparing for the Data Managers Meeting in the fall. Last year the STS requested that all primary data and file contacts update their contact information to ensure the STS National Database participant listing contains accurate information. Feedback produced positive results, and the STS has decided to make this an annual event. Please e-mail Lauracyn Montgomery at lmontgomery@sts.org by August 2, 2004 if your institution's primary data and file contact information has changed.
