General description

The Outpatient Activity Minimum Dataset (OP MDS) was introduced in Wales in April 1999. The dataset records patient level information on outpatient activity in the NHS in Wales. The dataset was originally designed to capture consultant led activity but has expanded to capture independent nurse led activity. Information is collected on a monthly basis and held by the NHS Wales Informatics Service (NWIS).

From 2012-13 onwards, the OP MDS is the source of official statistics for outpatient activity in the NHS in Wales, rather than the previous QS1 return. Although the QS1 was the source of official statistics for 2011-12 we have also published data for 2011-12 from the OP MDS to allow comparisons to be made between the old and current data sources.

The figures provided are based on activity undertaken at hospital sites in Wales. As such, it includes activity delivered by English organisations in Welsh hospitals and excludes activity carried out in England.

The drop in Cardiff and Vale’s outpatients who did not attend between 2014-15 and 2015-16 is mainly due the introduction of a Fully Automated Booking (FAB) system. The drop in Cwm Taf’s activity between 2014-15 and 2015-16 is mainly due to a change in the data they submit to bring them in-line with national reporting standards. These are explained in more detail in Section 3 of the statistical article ‘Outpatient Activity Minimum Dataset: update on data quality and summary results for 2015-16’.

From April 2016, there has been a change in the treatment function codes submitted by the local health boards, please see the release for more information.

The increase in Cwm Taf in 2016-17 is mainly due to some hospital sites submitting data for the first time, which is explained in more detail in the statistical release.

Please see the statistical article “Outpatient Activity Minimum Dataset: publication of data and discussion of data quality” published on 16 February 2016 for information on the OP MDS, including differences between this data source and the QS1 and also data quality information. Please also see ‘Outpatient Activity Minimum Dataset: update on data quality and summary results for 2015-16’ published on 04 October 2016.

Data collection and calculation

LHBs and Trusts are required to submit monthly OP MDS data to NWIS by the 20th calendar day of the following month. The data is thereafter loaded into the national data base.

NWIS supply this data to Welsh Government annually and the data supplied covers each financial year.

Revisions information

This data was revised on 13/12/18 to fix duplications in health board totals. Wales and hospital figures were unaffected.

We plan to revise data for the previous year on an annual basis, at the same time that we release new data. We will take advice from NWIS regarding revisions for previous years. For example, if resubmissions from LHBs/NHS trusts are large, the data will be revised. Revised data will be highlighted in the StatsWales table as such.
