National Booking Reporting System Data Warehouse (NBRS DW)

Scope

Purpose
The National Booking Reporting System Data Warehouse (NBRS DW) was established to consolidate information from the NBRS database and summary outpatient statistics. This consolidated view of the data supports the monthly production of Elective Services Patient Flow Indicator (ESPI) reports and ad hoc queries. The ESPIs are a means of evaluating how providers manage pzatients waiting for access to elective services. The eight indicators incorporate the Government’s policy targets for elective services and some of the accountability requirements for District Health Boards (DHBs). In addition, they highlight current and potential issues in patient flows through the elective services system.

Content
The NBRS DW is updated every month with the last six months of data from:

• the NBRS, which is a collection of all booking system events involving a healthcare user who receives an assessment of priority for a medical or surgical service and who is accepted for publicly funded treatment; this data is collected from the 21 DHBss
• the Monthly Reporting Access database, which contains national summary outpatient data; this data is collected monthly from the 21 DHBs.

Start date

The NBRS DW was implemented on 1 July 2003, and contains data from 1 August 2000.

Guide for use

At the end of each month, the previous six months’ data is loaded to ensure any changes are captured. Data is summarised into months (also known as snapshots).

Security of data

The NBRS Data Warehouse is accessed by authorised NZHIS staff for maintenance, data quality, analytical, and audit purposes.
Authorised users from the Ministry of Health’s Elective Services Team and DHBs have access to the data for analytical purposes via the Business Objects reporting tool and the secure Health Information Network. Business Objects contains a subset of the data described in the Data Dictionary.

Privacy issues

The Ministry of Health is required to ensure that the release of information recognises any legislation related to the privacy of health information, in particular the Official Information Act 1982, the Privacy Act 1993, and the Health Information Privacy Code 1994.
Information available to the general public is of a statistical and non-identifiable nature. Researchers requiring identifiable data will usually need approval from an Ethics Committee.

National reports and publications

Summary NBRS data is published on the elective services web site www.electiveservices.govt.nz as part of the ESPIs. These reports are also available via the Business Objects reporting tool.

Data provision

Customised datasets or summary reports are available on request, either electronically or on paper. Staff from the NZHIS Analytical Services team can help to define the specifications for a request and are familiar with the strengths and weaknesses of the data.
The NZHIS Analytical Services team also offer a peer review service to ensure that NZHIS data is reported appropriately when published by other organisations.
There may be charges associated with data extracts.
