Glossary Acronym/Word BI BOXI BOXI Universe Case CDD CDW CHI Contact Data mart Episode ETL Fact WIFT Description Business Intelligence. Business Objects XI is a web-based reporting tool that allows users to create reports which can be made available to other users who have the appropriate access permissions. The BOXI universe is the reporting environment which is built on and allows access to the associated data mart. A case is used to identify a patient s single episode with the nursing service. Within a single case a patient may have multiple contacts with health care professionals. Common Dimensions Database the database which holds all of the common dimension tables used by the data marts within the Corporate Data Warehouse. The Corporate Data Warehouse is a central data store maintained by N IT. It is made up of a collection of independent data marts which share a common database for reference information. Community Health Index number a unique patient identifier which is issued to residents in cotland when they register with NH cotland. An interaction between the patient and the District Nurse during an episode of care. A subset of a data warehouse which has been designed to satisfy a particular function or reporting area within an organisation. A data mart can be designed and developed independently of other data marts. A data warehouse will contain multiple data marts. The period of care whilst the patient is part of the District Nurse s caseload. Extract, Transform and Load - The process of extracting data from external sources, transforming the data if necessary to meet operational needs and loading it into the data warehouse. A fact is a table in a data mart which contains data, usually measures, which can be reported on. The measures can usually (but not always) be aggregated at a dimensional level, e.g. a count of patients can be aggregated to give the counts per location, organisation etc. ubmission with internet file transfer Version 1.0 Page 3 of 22

1. Introduction 1.1. Purpose The purpose of this document is to detail the file schemas and processing rules for files submitted to a District Nursing data mart. The signed off document will be used in conjunction with other supporting documentation by the BI team to develop the data mart as specified. This document is intended to give details of the file specifications and how the files will be processed into the data mart. It is not intended to provide recording guidance. 1.2. Overview District nursing data will be submitted by the NH Boards and will be held in the Corporate Data Warehouse in a District Nursing data mart. This will be delivered as part of the first phase of the Community Health Activity Data (CHAD) project. 1.3. General Data Assumptions The following general assumptions have been made about the data being submitted All files will be sent from a single location within a NH Board, i.e. multiple sites will not be responsible for submitting information for the NH Board. The NH Board code used in the header record to identify which NH Board has submitted the data will be included as a data item in the data mart to identify the NH Board of Treatment. A patient can have more than one episode or contact. An episode can have zero or many contacts. A contact does not have to be associated with an episode. There is no interdependency between the files, e.g. a submission does not need to contain both an episode and a contact record for the patient. Unique Record ID It must be possible to uniquely identify an episode and contact record to avoid duplicate records being processed and to allow records to be updated if required. All NH Boards will be able to provide a system generated Unique Record ID o The Episode ID will uniquely identify an episode within the NH Board. The Episode ID will be fixed for a given episode and will not differ between the original episode and any update to that episode. This will allow Episode information to be updated. o The Contact ID will uniquely identify a contact within the NH Board. The Contact ID will be fixed for a given contact and will not differ between the original contact and any update to that contact. This will allow Contact information to be updated. Version 1.0 Page 5 of 22
2. File Extracts Extract Type Description Number of Records per file EPIODE The file will contain episode records which have been added or updated during the previous quarter. 50,000 per quarter CONTACT An episode starts when a patient is added to a District Nurse s caseload and ends when the patient is discharged from the caseload. The file will contain contact records which have been added or updated during the previous quarter. 200,000 per quarter A contact is an interaction between the patient and District Nurse during an episode of care. An episode can have multiple contacts. NOTE 1. There is no requirement for a separate historic data load. Any historic data submissions will conform to this specification. 3. File ubmission The files will be submitted using WIFT. WIFT is currently being used to submit test files. The destination location of the WIFT account will be modified so that files are transferred to the source directory for the data mart. 4. File Processing The files will be processed using an insert and update process. The following logic will be applied If a record is submitted and the Unique Record ID does not exist in the data table the record will be inserted/added to the data table. If a record is submitted and the Unique Record ID already exists in the data table it will overwrite the record already held in full - it is not a selective update so the update record must contain all of the relevant information. It is important that the latest record submitted for a Unique Record ID contains all of the relevant information. Records can be submitted or resubmitted from any historic timeframe if required. Records cannot be automatically deleted. If a record needs to be deleted a fast track CR will be raised to have the record removed. Version 1.0 Page 6 of 22
4.1. File Processing chedule The automated file load process will run at 6pm on weekdays. The file polling will increase 6 weeks after the end of a Quarter to run three times daily at 11am, 3pm and 6pm for 2 weeks only. 5. Validation The validation rules are specified in Appendix A. If any records fail a validation rule the file will fail and the error must be corrected and the file resubmitted. The file will go through two stages of validation as detailed in the table below. For the data validation to begin the file must pass the initial file validation stage. Validation tage File Error Type Description Outcome of Validation Rule Failure File Name Header chema The format of the file is validated, e.g. file name, header record, number of columns. The file will fail. The error must be corrected by the NH Board and the file resubmitted. Data Data The content of the file is validated. The record will fail. The error must be corrected by the NH Board and the record resubmitted. 5.1. Accessing Validation Results Validation results will be accessed using Business Objects. 6. Automated Emails The following emails will be generated. The emails can be sent to multiple recipients. Email Description Recipient Passed Contains details of the file submitted and that it passed validation. NH Board (email address(s) to be provided). CHAD support mailbox N.CommunityActivityData@nhs.net Failed Contains details of the file submitted. The number of records processed. The number of records which passed validation. The number of records which failed validation. If the file has failed totally it will include an Version 1.0 Page 7 of 22 ID Data Management mailbox nss.datamarts@nhs.net NH Board (email address(s) to be provided). CHAD support mailbox N.CommunityActivityData@nhs.net
Email Description Recipient indication of why the file could not be processed. ID Data Management mailbox nss.datamarts@nhs.net Loaded The data will not be available immediately after NH Board (email address(s) to be validation because of the processing required. provided). This email will advise when the data are available for analysis. CHAD support mailbox N.CommunityActivityData@nhs.net ID Data Management mailbox nss.datamarts@nhs.net 7. File Format The data extract(s) will follow the general standards. 7.1. File Name The file will fail validation if the file name does not conform to the following format. DATAMART_EXTRACT TYPE_ENDING LOCATION_EXTRACT DATE. EXTENION e.g. DNURE_EPIODE_N_20150114.csv Where: Item Description Example Data Mart Identifies the data mart which the files are submitted to DNURE Extract Type The type of file extract: Episode or Contact EPIODE ending Location The cipher for the sending location e.g. N = Grampian N ee Appendix A for valid sending locations. Extract Date The date the file was compiled. Date format: YYYYMMDD 20150114 File extension Identifies the type of file, must be a.csv.csv 7.2. Header Record The first row in the file must contain a header record which contains details of the file. All data items in the header record are mandatory and must be in the specified format. The information in the header record should be consistent with the information supplied in the file name. The file will fail validation if the header format does not conform to the following comma delimited format. DATA MART,EXTRACT TYPE,ENDING LOCATION,EXTRACT DATE,UBMIION REFERENCE NUMBER,RECORD COUNT e.g. DNURE,EPIODE,N,20150114,1,12100 Version 1.0 Page 8 of 22
Where: Item Format Description Example Data Mart Varchar (6) Identifies the data mart which the files are DNURE submitted to Extract Type Varchar (15) The type of file extract: Episode or Contact EPIODE ending Location Varchar (1) The cipher for the sending NH Board e.g. N = N Grampian. ee Appendix B for valid sending locations. Extract Date Varchar (8) The date the file was compiled. Date format: 20150114 YYYYMMDD ubmission Integer (6) A unique number identifying the number of the 1 Reference Number submission for the sending location. Record Count Integer A count of the number of records in the file (excluding the header record and column names). 12100 NOTE 1. The header record is not case sensitive. 2. The ubmission Reference Number is required to allow multiple files for the same location to be processed in the correct order, and to flag if there are any gaps in the received files. The ubmission Reference Number should increment per successful validation for each sending location. Files which are invalid and rejected for any reason must be corrected and resubmitted with the same ubmission Reference Number as the original. 3. There should be no characters (including commas) after the last item. 7.3. General File Rules The following table include the general rules which apply to the file format Category Columns Column Names Column Width Blank Rows Null/Missing Values paces (nonprintable values) Description The columns are comma delimited to separate fields and must be in the order specified in the file specification. If a field is empty the column must still be included in the extract. The file will contain column name headings. The headings are for local use only and will be ignored when the file is loaded. The name can only contain a comma when surrounded by double quotes. The column width is the minimum width from a development perspective. The data mart will be developed to process columns with a width wider than documented to ensure that the field is not truncated to a valid value. Blank data rows must not be included in the data file. Empty fields will indicate where a value is null (missing). Zero must not be used. paces should not be present between fields. The comma alone should delimit fields. Version 1.0 Page 9 of 22
7.4. Data Element Rules The following table includes the data element rules which apply to the data in the file Category Number Type Text/Character Type Description Numeric data items will appear in the text file as a string of continuous numeric digits. For large numbers the thousand display format characters such as the comma will not be included. Where the number contains decimals, the period character. will be used as the decimal point. The text string will contain any alphanumeric character including the space character other than double quotes. The format of the text field will be defined as Varchar (n) where Varchar (n) is a variable length string of maximum length n. Free text fields should be qualified/surrounded by double quotes. Codes and descriptions will be converted to upper case for all data items. Date Type A column containing date strings will be formatted as DDMMCCYY (e.g. 14012015). Time Type Leading Zeros If a 7 digit date is submitted it will be left zero padded to 8 digits. A column containing date time strings will be formatted as HH:MM using the 24 hour clock (e.g. 17:35). Leading zeros must not be stripped off codes which have been identified as having leading zeros. Data Item Priorities If a 9 digit CHI number is submitted it will be left zero padded to 10 digits. The priority categories for including data items are as follows. M = Mandatory the data item must be populated = hould be populated if available O = Optional 7.5.
