You will be prompted to enter the name of the target destination.GENERAL DOCUMENTATIONOVERVIEWThe General Documentation consists of six sections:PART A. BACKGROUND INFORMATION: Part A provides information on the quarterly reporting periods and the development of the FY2011 Emergency Department Visit Database.PART B. DATA: Part B describes the basic data quality standards as contained in Regulation 114.1 CMR 17.00: Requirement for the Submission of Hospital Case Mix and Charge Data, some general data definitions, general data caveats, and information on specific data elements.Case mix data plays a vital and growing role in health care research and analysis. To ensure the database is as accurate as possible, CHIA strongly encourages hospitals to verify the accuracy of their data. A standard Verification Report Response Form is issued by CHIA, and is used by each hospital to verify the accuracy of their data as it appears on their FY2011 Final Case-mix Verification Report. If a hospital finds data discrepancies, CHIA requests that the hospital submit written corrections that provide an accurate profile of that hospital’s discharges.PART C. HOSPITAL RESPONSES: Part C details hospital responses received as a result of the data verification process. From this section users can also learn which hospitals did not verify their data. This section contains the following lists and charts:Summary of Hospitals’ FY2011 Verification Report ResponsesIndividual Hospital Discrepancy DocumentationPART D. CAUTIONARY USE HOSPITALS: Part D lists the hospitals for which CHIA did not receive four (4) quarters of acceptable hospital discharge data, as specified under Regulation 114.1 CMR 17.00.For 2011, all hospitals were in compliance.PART E. HOSPITALS SUBMITTING DATA: Part E lists Hospital discharge and charge totals by quarter for data submissions.PART F. SUPPLEMENTARY INFORMATION: Part F provides Supplements I through III listed in the Table of Contents. It contains specific information about Error types, Hospital names and addresses, and Hospital name and affiliation changes.PART A: BACKGROUND INFORMATION1. QUARTERLY REPORTING PERIODSMassachusetts hospitals are required to file case-mix data which describes various characteristics of their patient population, as well as the charges for services provided to their patients in accordance with Regulation 114.1 CMR 17.00. Hospitals report data to CHIA on a quarterly basis. For the 2011 period, these quarterly reporting intervals were as follows:Quarter 1:October 1, 2010 – December 31, 2010Quarter 2:January 1, 2011 – March 31, 2011Quarter3:April 1, 2011 – June 30, 2011Quarter 4:July 1, 2011 – September 30, 20112. DEVELOPMENT OF THE FISCAL YEAR DATABASEThe Massachusetts Center for Health Information and Analysis adopted final regulations regarding the collection of emergency department data from Massachusetts’ hospitals, effective October 1, 2001. They are contained in Regulation 114.1 CMR 17.00, and the Outpatient Emergency Department Visit Data Electronic Records Submission Specification, both of which are available on CHIA’s website.The ED database captures data concerning visits to emergency departments in Massachusetts’ acute care hospitals and satellite emergency facilities that do not result in admission to an inpatient or outpatient observation stay. To avoid duplicate reporting, data on ED patients admitted to observation stays will continue to be reported to the Outpatient Observation Stay database, and ED patients admitted as inpatients will continue to be reported to the inpatient Hospital Discharge Database. CHIA has asked providers to flag those patients admitted from the ED in the inpatient and outpatient observations databases, and to provide overall ED utilization statistics to ensure that all ED patients are accurately accounted for.DATA RELEASE LEVELSSix Fiscal Year 2011 data levels have been created to correspond to the levels in Regulation 114.5 CMR 2.00; “Disclosure of Hospital Case Mix and Charge Data”.Higher levels contain an increasing number of the data elements defined as “Deniable Data Elements” in Regulation 114.5 CMR 2.00. The deniable data elements include: medical record number, billing number, Medicaid Claim Certificate Number (Medicaid Recipient ID number), unique health information (UHIN) number, beginning and ending dates of service, date of birth, date(s) of surgery, and the unique physician number (UPN). The six levels include:LEVEL IContains all case mix data elements, except the deniable data elementsLEVEL IIContains all Level I data elements, plus the UPNLEVEL IIIContains all Level I data elements, plus the patient UHIN, the mother’s UHIN, an admission sequence number for each UHIN admission record, and may include the number of days between inpatient stays for each UHIN record.LEVEL IVContains all Level I data elements, plus the UPN, the UHIN, the mother’s UHIN, an admission sequence number for each UHIN admission record, and may include the number of days between inpatient stays for each UHIN record.LEVEL VContains all Level IV data elements, plus the date of admission, date of discharge, and the date(s) of surgery.LEVEL VIContains all of the deniable data elements except the patient identifier component of the Medicaid recipient ID number.PART B. DATA1. DATA QUALITY STANDARDSData Edits:The Case Mix Requirement Regulation 114.1 CMR 17.00 requires hospitals to submit emergency department data to CHIA 75 days after each quarter. The quarterly data is edited for compliance with regulatory requirements, as specified in the Outpatient Emergency Department Visit Data Electronic Records Submission Specification.The standards employed for rejecting data submissions from hospitals are based upon the presence of Category A or B errors as listed for each data element under the following conditions.All errors are recorded for each patient Record and for the Submission as a whole. An Edit Report is provided to the hospital, displaying detail for all errors found in the submission.A patient Record is rejected if there is:?Presence of one or more errors for Category A elements.?Presence of two or more errors for Category B elements. A hospital data Submission will be rejected if:?1% or more of discharges are rejected; or?50 consecutive records are rejected.Each hospital received a quarterly error report displaying invalid discharge information. Quarterly data that does not meet the one percent compliance standard must be resubmitted by the individual hospital within 30 days, until the standard is met.Please see Supplement I for a Table of Field Names and Error Types, and the Data Elements section for descriptions of fields.Verification Report Process:The Verification Report process is intended to present hospitals with a profile of their individual data as reported and retained by CHIA. The purpose of this process is to function as a quality control measure for hospitals. It allows the hospitals the opportunity to review the data they have provided to CHIA and to affirm its accuracy. The Verification Report itself is a series of frequency reports covering selected data elements. Please refer to Supplement III for a description of the Verification Report contents.The Verification Report is produced after a hospital has successfully submitted the four quarters of data. The hospital is then asked to review and verify the data contained within the report. Hospitals need to affirm to CHIA that the data reported is accurate or to identify any discrepancies. All hospitals are strongly encouraged to closely review their report for inaccuracies and to make corrections so that subsequent quarters of data will be accurate. Hospitals are then asked to certify the accuracy of their data by completing an Emergency Department Verification Report Response Form.The Verification Report Response Form allows for two types of responses as follows:“A” Response: By checking this category, a hospital indicates its agreement that the data appearing on the Verification Report is accurate and that it represents the hospital’s case mix profile.“B” Response: By checking this category, a hospital indicates that the data on the report is accurate except for the discrepancies noted.If any data discrepancies exist (e.g., a “B” response), CHIA requests that hospitals provide written explanations of the discrepancies, so that they may be included in the General Documentation Manual.Note: The verification reports are available for review. Please direct requests to the attention of Public Records by facsimile to fax #617-727-7662, or by emailing a request to CHIA at Public.Records@state.ma.us.2. GENERAL DEFINITIONSBefore turning to a description of the specific data elements, several basic definitions (as contained in Regulation 114.1 CMR 17.02) should be noted.Emergency Department (ED)The department of a hospital or a health care facility off the premises of a hospital that is listed on the license of a hospital and qualifies as a Satellite Emergency Facility under 105 CMR 130-820 through 130.836, that provides emergency services as defined in 105 CMR 130.020. Emergency services are further defined in the HURM, Chapter III, s. 3242.Emergency Department VisitAny visit by a patient to an emergency department for which the patient is registered at the ED, but which results in neither an outpatient observation stay nor the inpatient admission of the patient at the reporting facility. An ED visit occurs even if the only service provided to a registered patient is triage or screening. An ED visit is further defined in the HURM Chapter III, s. 3242.3. GENERAL DATA CAVEATSInformation may not be entirely consistent from hospital to hospital due to differences in:Collection and verification of patient supplied information at the time of arrival;Medical Record coding, consistency, and/or completeness;Extent of hospital data processing capabilities;Extent of hospital data processing systems;Varying degrees of commitment to quality of emergency department data;Non-comparability of data collection and reporting.Emergency Department DataThe emergency department data is derived from information gathered upon arrival, or from information entered by attending physicians, nurses, and other medical personnel into the medical record. The quality of the data is dependent upon hospital data collection policies and coding practices of the medical record staff4. SPECIFIC DATA ELEMENTSThe purpose of the following section is to provide the user with an explanation of some of the specific data elements included in the ED database, and to give a sense of their reliability.a) New Data Elements (as of October 1, 2006)Effective October 1, 2006, the following new data elements were added to Regulation 114.1 CMR 17.00. Additionally, new code values were added for race and patient status. Please note that implementation took place in two phases.Patient RacePreviously there was a single field to report patient race. Beginning this year, there are three fields to report race. Race 1, Race 2, and Other Race (a free text field for reporting any additional races). Also, race codes have been updated. Please see the Data Codes section for a listing of updated values. These are consistent with both the federal OMB standards and code set values, and the EOHHS Standards for Massachusetts.Hispanic IndicatorA flag to indicate whether the patient is or is not Hispanic/Latino/Spanish.EthnicityThree fields – separate from patient race -- to report patient ethnicity. Ethnicity 1, Ethnicity 2, and Other Ethnicity (a free text field for reporting additional ethnicities). Please see the Data Codes section for a listing of the 33 ethnicities.Condition Present on Admission IndicatorThis is a qualifier for each diagnosis code (Primary, Diagnosis I – XIV, and primary E-Code field) indicating onset of diagnosis preceded or followed admission.Permanent & Temporary US Patient AddressPatient address includes the following fields: Patient Street AddressPatient City/TownPatient StatePermanent Patient Country (ISO-3166)b) Existing Data ElementsFiling Org DPH NumberThe Massachusetts Department of Public Health’s four-digit identification number for the hospital that submits the data. A hospital may submit data for multiple affiliated hospitals or campuses.Filing Org IDAn identification number assigned by CHIA to the hospital that submits the data. A hospital may submit data for multiple affiliated hospitals or campuses.Type of VisitThis is the patient’s type of visit: Emergency, Urgent, Non-Urgent, Newborn, or Unavailable. Please note it is expected that Newborn will not be a frequently used value for Type of Visit in the ED database (in contrast to its frequent use as a Type of Admission in the Inpatient database), since few babies are born in Eds. However, it would be appropriately reported as a Type of Visit for an ED visit if there were a precipitous birth that actually occurred in the ED, or if the baby was born out of the hospital but it was brought immediately thereafter to the ED for care. Reporting patterns vary widely from hospital to hospital and may not be reliable.Emergency Severity IndexThe Emergency Severity Index (ESI) is a system for triaging patients using an algorithm developed by researchers at Brigham & Women’s and Johns Hopkins Hospitals. It employs a five-level scale. It may be reported on Record Type 20 as an alternative to, or in addition to, the Type of Visit (Field 17), which is basically a three-level triage scale. The ESI is described in the following article: Wuerz, R. et al., Reliability and Validity of a New Five-Level Triage Instrument, Academic Emergency Medicine 2000; 7:236-242. Regardless of whether the ESI or the Type of Visit is reported, it should reflect the initial assessment of the patient, and not a subsequent revision of it due to information gathered during the course of the ED visit. Only a small number of hospitals report this data element.Source of VisitThis is the patient’s originating, referring, or transferring source of visit in the ED. It includes Direct Physician Referral, Within Hospital Clinic Referral, Direct Health Plan Referral/HMO Referral, Transfer from an Acute Care Hospital, Transfer from a Skilled Nursing Facility, Transfer from an Intermediate Facility, and Walk-In/Self-Referral. Newborn Source of Visits includes Normal Delivery, Premature Delivery, Sick Baby, and Extramural Birth. Reporting patterns may vary widely from hospital to hospital and may not be reliable.Secondary Source of VisitThis is the patient’s secondary referring, or transferring source of visit in the ED. This is infrequently reported for ED Visits.ChargesThis is the grand total of charges associated with the patient’s ED visit. The total charge amount should be rounded to the nearest dollar. A charge of $0 is not permitted unless the patient has a departure status of eloped, left against medical advice, or met personal physician in the ED.Encrypted Physician Number (UPN)This is the state license number (Mass. Board of Registration in Medicine license number) for the physician who had primary responsibility for the patient’s care in the ED. This may also be the state license number for a dental surgeon, podiatrist, or other (i.e., non-permanent licensed physician) or midwife. This item is provided in encrypted form.Other Physician Number (UPN)This is the state license number (Mass. Board of Registration in Medicine license number) for the physician other than the ED physician who provided services related to the patient’s visit. This may also be the state license number for a dental surgeon, podiatrist, or other (i.e., non-permanent licensed physician) or midwife. This item is provided in encrypted form.Other Caregiver CodeThis is the code for the other caregiver with significant responsibility for the patient’s care. It includes resident, intern, nurse practitioner, or physician’s assistant.Principal DiagnosisThis is the ICD-9-CM code (excluding decimal point) for the patient’s principal diagnosis. Associated Diagnosis Codes 1-5The ICD-9-CM codes (excluding decimal point) for the patient’s first, second, third, fourth, and fifth associated diagnoses, respectively.Significant Procedure Code 1-4These are the ICD-9-CM codes (excluding decimal point) or CPT codes for the patient’s significant procedures, as reported in FL 80 and FL 81 of the UB-92. More detailed information on the items and services provided during the ED visit is reported under the Service Line Item data.Associated Significant Procedure Codes 1-3These are the ICD-9-CM codes (excluding decimal point) or CPT codes for the patient’s first, second, and third associated significant procedure, as reported in FL 82 of the UB-92.Procedure Type CodeThis is the coding system (CPT or ICD-9-CM) used to report significant procedures in the patient’s record. Only one coding system is allowed per patient visit.Ambulance Run Sheet NumberThe purpose of the Ambulance Run Sheet Number is to permit association of the ED data with data on pre-hospital services that patients may receive. The pre-hospital database is currently being developed by the Department of Public Health. This will not be a required element until the pre-hospital services database is in operation.Patient Departure Status CodePatient Departure Status Code is used to report the status of the patient at the time of discharge. Patients who are registered in the ED, but who then leave before they are seen and evaluated by a physician are said to have “eloped”. In contrast, patient who have been seen by a physician but who leave against the medical advice of that physician are coded as AMA (Against Medical Advice). Patients who die during their visit to the ED (expired) are distinguished from patient who were “dead on arrival” (DOA), whether or not resuscitation efforts were undertaken. Such distinctions are valuable when doing outcomes studies related to both pre-hospital and ED care.Patient’s Mode of Transport CodeThis is the patient’s mode of transport to the ED. It includes by Ambulance, by Helicopter, law Enforcement, and Walk-In (including public or private transport).Discharge Date and Discharge TimeThe discharge date and discharge time reflect the actual date and time that the patient was discharged from the ED. Default values, such as 11:59 PM of the day the patient was registered, are unacceptable. Time is reported as military time, and valid values include 0000 through 2359. (Please note that Discharge Time was mandatory beginning 10/1/2002 for FY2003.)Stated Reason For VisitThe Reason for Visit is the patient’s reason for visiting the ED. It is also known as the Chief Complaint. This should be the problem as perceived by the patient, as opposed to the medical diagnosis made by a medical professional. Because of the lack of a commonly used coding system for Reason for Visit, this field is reported in a free text field (up to 150 characters in length). (Please note that Reason for Visit was mandatory beginning 10/1/2002 for FY2003).Patient Homelessness IndicatorThe patient Homelessness Indicator is used to identify patients that are homeless. CHIA recognizes that homeless patients do not always identify themselves as such. Neither does CHIA expect hospitals to specifically ask patients whether they are homeless, if this is not their practice. However, because the homeless are a population of special concern with regard to access to care, health outcomes, etc., it is useful to identify as many of these patients as possible. If a patient reports no home address, provides the address of a known homeless shelter, or otherwise indicates that he or she is homeless, that should be indicated in this field by using a coding value of Y. Otherwise, the hospital should use the value N. (Please note that this field was mandatory beginning 10/1/2002 for FY2003.)Principal External Cause of Injury Code (E-Code)The ICD-9-CM code categorizes the event and condition describing the principal external cause of injuries, poisonings and adverse effects.Payer CodesA complete listing of the payer types and sources can be found in this manual under the Technical Documentation.Unique Health Identification Number (UHIN)The patient’s social security number is reported as a nine-digit number, which is then encrypted by CHIA into a Unique Health Information Number (UHIN). Therefore, the social security number is never considered a case mix data element. Only the UHIN is considered a database element and only the encrypted number is used by CHIA. Please note that per Regulation 114.1 CMR 17.00, the number reported for the patient’s social security number should be the patient’s social security number, not the social security number of some other person, such as the husband or the wife of the patient. Likewise, the social security number for the mother of a newborn should not be reported in this field, as there is a separate field designated for the social security number of the newborn’s mother.Service Line ItemsService Line Items are the CPT or HCPCS Level II codes used to bill for specific items and services provided by the ED during the visit. In addition, the code DRUGS is used to report provision of any drugs for which there are no specific HCPCS codes available. Likewise, SPPLY is used to report any supplies for which there are no specific HCPCS codes available. Since units of service are NOT collected in the database, it is possible that the item or service which a reported service line item code represents was actually provided to the patient more than once during the visit.ED Treatment BedThe purpose of this data element is to help measure the normal capacity of Eds. ED Treatment Bed includes only those beds in the ED that are set up and equipped on a permanent basis to treat patients. It does not include the temporary use of gurneys, stretchers, etc. Including stretchers, etc. would overestimate hospitals’ physical capacity to comfortably treat a certain volume of ED patients, although CHIA recognizes that in cases of overcrowding, EDs’ may need to employ temporary beds.ED-Based Observation BedED-based Observation Beds are beds located in a distinct area within or adjacent to the ED, which are intended for use by observation patients. Hospitals should include only beds that are set up and equipped on a permanent basis to treat patients. They should not include temporary use of stretchers, gurneys, etc.ED SiteMost hospitals submitting ED data provide emergency care at only one location. Therefore, they are considered to have a single campus or site, and need to summarize their data only once. However, others may be submitting data pertaining to care provided at multiple sites. CHIA requires the latter to summarize their data separately for each site covered by the data submitted.5. CHIA CALCULATED FIELDSAnalysis of the UHIN data by CHIA has turned up problems with some of the reported data for the inpatient and outpatient observation stays databases. For a small number of hospitals, little or no UHIN data exists as these hospitals failed to report patients’ social security numbers (SSN). Other hospitals reported the same SSN repeatedly resulting in numerous visits for one UHIN. In other cases, the demographic information (age, sex, etc.) was not consistent when a match did exist with the UHIN. Some explanations for this include assignment of a mother’s SSN to her infant or assignment of a spouse’s SSN to a patient. This demographic analysis shows a probable error rate in the range of 2% - 10%.In the past, CHIA has found that, on average, 91% of the SSNs submitted are valid when edited for compliance with rules issued by the Social Security Administration. Staff continually monitors the encryption process to ensure that duplicate UHINs are not inappropriately generated, and that recurring SSNs consistently encrypt to the same UHIN.Only valid SSNs are encrypted to a UHIN. It is valid for hospitals to report that the SSN is unknown. In these cases, the UHIN appears as ‘000000001’.Invalid SSNs are assigned 7 or 8 dashes and an error code. The list of error codes is as follows:ssn_empty = 1 ssn_notninechars = 2 ssn_allcharsequal = 3 ssn_firstthreecharszero = 4 ssn_midtwocharszero = 5 ssn_lastfourcharszero = 6 ssn_notnumeric = 7 ssn_rangeinvalid = 8 ssn_erroroccurred = 9 ssn_encrypterror = 10**Based on these findings, CHIA strongly suggests that users perform qualitative checks on the data prior to drawing conclusions about that data.PART C.

TECHNICAL DOCUMENTATIONOverviewFor your information, we have included a page of physical specifications for the data file at the beginning of this manual. Please refer to CD Specifications on page 2 for further details.Technical Documentation included in this section of the manual is as follows: Part A.Calculated Field DocumentationCalculated fields are: Age Newborn age in weeksUnique Health Information Number (UHIN) Sequence NumberEach description has three parts:First is a description of any Conventions. For example, how are missing values used?Second is a Brief Description of how the fields are calculated. This description leaves out some of the detail. However, with the first section it gives a good working knowledge of the field.Third is a Detailed Description of how the calculation is performed. This description follows the code very closely.Part B.Data Code Tables SummaryED Data Code Tables are listed in this section.Other Technical Documentation Resources:Data Release File Specifications:Specifications outlining the ED data release file fields and Access 3 database structure for the various ED Data Release Levels are in development at the time of release of this document. When complete these will be published on the CHIA website.Submission File Specifications:For a record layout and description of each field along with the starting and ending positions, as specified for Hospital ED submission files, refer to the Outpatient Emergency Department Visit Data Electronic Records Submission Specification on the CHIA website: or A. CALCULATED FIELD DOCUMENTATION1. AGE CALCULATIONS A) Conventions:1) Age is calculated if the date of birth and admission date are valid. If either one is invalid, then ‘999’ is placed in this field.2) Discretion should be used whenever a questionable age assignment is noted. Researchers are advised to consider other data elements (i.e., if the admission type is newborn) in their analysis of this field.B) Brief Description:Age is calculated by subtracting the date of birth from the admission date.C) Detailed Description:If the patient has already had a birthday for the year, his or her age is calculated by subtracting the year of birth from the year of admission. If not, then the patient’s age is the year of admission minus the year of birth, minus one.2. NEWBORN AGE CALCULATIONSA) Conventions:1) Newborn age is calculated to the nearest week (the remainder is dropped). Thus, newborns zero to six days old are considered to be zero weeks old.2) Discharges that are not newborns have ‘99’ in this field.B) Brief Description:Discharges less than one year old have their age calculated by subtracting the date of birth from the admission date. This gives the patient’s age in days. This number is divided by seven, the remainder is dropped.C) Detailed Description:1) If a patient is 1 year old or older, the age in weeks is set to ‘99’.2) If a patient is less than 1 year old then:a) Patients’ age is calculated in days using the Length of Stay (LOS) routine, described in (B) above. b) Number of days in step ‘a’ above is divided by seven, and the remainder is dropped.3. UNIQUE HEALTH INFORMATION NUMBER (UHIN) VISIT SEQUENCE NUMBER A) Conventions:If the Unique Health Information Number (UHIN) is undefined (not reported, unknown or invalid), the sequence number is set to zero.B) Brief Description:The Sequence Number is calculated by sorting the file by UHIN, registration date, and discharge date. The sequence number is then calculated by incrementing a counter for each UHIN’s set of visits.C) Detailed Description:1) UHIN Sequence Number is calculated by sorting the entire database by UHIN, registration date, then discharge date (both dates are sorted in ascending order).2) If the UHIN is undefined (not reported, unknown or invalid), the sequence number is set to zero.3) If the UHIN is valid, the sequence number is calculated by incrementing a counter from 1 to nnnn, where a sequence number of 1 indicates the first visit for the UHIN, and nnnn indicates the last visit for the UHIN.4) If a UHIN has 2 visits on the same day, the discharge date is used as the secondary sort key.PART B. OUTPATIENT EMERGENCY DEPARTMENT DATA CODE TABLESPlease refer to Outpatient Emergency Department Visit Data Electronic Records Submission Specification on the CHIA website for information regarding the Outpatient Emergency Department Data Code tables for all data elements requiring codes not otherwise specified in 114.1 CMR 17.00. or specification contains the ED submission file record layout and field requirements, as well as lists and descriptions of the expected values for the following ED data code tables:IDHCFP Organization IDs for HospitalsPayer Type CodeSource of Payment Code Patient Sex Patient Race Patient Hispanic IndicatorPatient EthnicityType of Visit Source of VisitPatient Departure Status CodeOther Caregiver Code Patient’s Mode of Transport Homeless Indicator Condition Present on Visit Flag ................
