This publication provides the most timely statistics available relating to NHS funded secondary mental health, learning disabilities and autism services in England. This information will be of use to people needing access to information quickly for operational decision making and other purposes. These statistics are derived from submissions made using version 3.0 of the Mental Health Services Dataset (MHSDS). This edition includes final statistics for February 2019 and provisional statistics for March 2019. NHS Digital review the quality and completeness of the submissions used to create these statistics on an ongoing basis. More information about this work can be found in the Accuracy and reliability section of this report. Fully detailed information on the quality and completeness of particular statistics in this release is not available due to the timescales involved in reviewing submissions and engaging with data providers. The information that has been obtained at the time of publication is made available in the Provider Feedback sections of the Data Quality Reports which accompany this release. Information gathered after publication is released in future editions of this publication series. More detailed information on the quality and completeness of these statistics and a summary of how these statistics may be interpreted is made available later in our Mental Health Bulletin: Annual Report publication series. All elements of this publication, other editions of this publication series, and related annual publication series' can be found in the Related Links below. Please note: The Quarter 4 Children and Young People Receiving Second Contact With Services measure will not be included in the June 2019 publication. A validation of this data is currently underway; we expect statistics for the full 2018/19 financial year to be published in the July 2019 publication. Please note: The provider breakdown for AMH04 (People in contact with adult mental health services on CPA at the end of RP with HoNOS recorded) has not been included in this publication and will not be included in future publications until the cause is rectified. NHS Digital will inform users once this issue has been resolved. NHS Digital apologises for any inconvenience caused. Notice of data item removal from MHSDS: NHS Digital are looking into the possibility of removing the CHILD AND ADOLESCENT MENTAL HEALTH TIER OF SERVICE (https://www.datadictionary.nhs.uk/data_dictionary/data_field_notes/c/ce/child_and_adolescent_mental_health_tier_of_service_de.asp) data element from MHSDS, to take effect from the April 2020 reporting period. If the data element is removed, national analysis will be carried out on the basis of an algorithm using existing information, including the patient’s derived age. This will remove a data item that is no longer relevant to common practice and help maintain focus on key remaining items. We are keen to understand the impact of removing this data element on organisations that currently receive a data extract including this field, or otherwise use data that will be impacted by its removal. If you have any concerns regarding the removal of this data element from MHSDS, please email NHS Digital at enquiries@nhsdigital.nhs.uk giving us as much information as possible about the type of organisation you represent, and the impact that removal of the data element will have on your work. Please contact us by 17:00 Monday 10 June 2019 and use ‘FOA of DSDS – Consultation on CAMHS Tier data item’ as the subject line in any communications.

This Zenodo entry details the methodology for extracting and reconciling ethnicity data from the Clinical Practice Research Datalink (CPRD), incorporating both General Practitioner (GP) and Hospital Episode Statistics (HES) sources. The approach aims to resolve discrepancies between these sources and provide a standardized single ethnicity value per patient, categorized into 6 and 12 levels according to NHS coding guidelines. Materials and Methods: Ethnicity data from the CPRD are recorded in multiple formats. This study harmonizes these data to achieve consistent ethnicity classification across patient records, following a hierarchal reconciliation protocol prioritizing hospital data over GP records. Ethnicity Levels: Ethnicity data are processed to conform to two levels of granularity: Six high-level categories: White, Black, Asian, Mixed, Other, Unknown Twelve detailed categories: Bangladeshi, Black African, Black Caribbean, Black Other, Chinese, Indian, Mixed, Other Asian, Other, Pakistani, Unknown, White Source Data Mapping: CPRD Medcodes: Directly mapped to 490 SNOMED codes SNOMED to NHS Codes: SNOMED codes are linked to 26 NHS ethnicity codes NHS to HES Codes: These NHS codes further map into 12 HES hospital ethnicities, which then consolidate into the 6 broad categories mentioned above Algorithm (AIM-CISC): Hospital Data Priority: Ethnicity records from hospital sources override those from GP records unless the hospital data is classified as "Unknown", null, or empty. Conflict Resolution Within GP Data: The frequency of recorded ethnicities determines the selection. The most frequently recorded ethnicity prevails. If frequencies are tied, the most recent record is used. In cases where records are equally recent, the first alphabetically listed ethnicity is selected. Unique Patient Identifiers: Each patient is represented once in hospital data, ensuring a single source of truth for hospital-based ethnicities. This simplifies reconciliation with GP data when discrepancies arise.

For example, two different Medcodes represent the New Zealand European ethnicity, which both map back to the identical SNOMED code.

Breastfeeding data at 10 days, 6 weeks and 6 months is collected through the Healthy Child Wales Programme. The delivery of this programme has been affected by COVID-19 and has resulted in a small increase of missing breastfeeding data in Apr-Jun 2020. The percentage of missing data for the quarter Jul-Sep 2020 is in line with pre-COVID-19 levels.

VIKING II was made possible thanks to Medical Research Council (MRC) funding. We aim to better understand what might cause diseases such as heart disease, eye disease, stroke, diabetes and others by inviting 4,000 people with 2 or more grandparents from Orkney and Shetland to complete a questionnaire and provide a saliva sample. This data dictionary outlines what volunteers were asked and indicates the data you can access. To access the data, please e-mail viking@ed.ac.uk.

Smoking at initial assessment: More than 90% of records had valid data for the smoking status at initial assessment data item, across all health boards, in all years. However, statistics on smoking at initial assessment and birth are limited by the way in which the data is collected. If CO monitoring is not available, data reliability is dependent on the mother self-reporting accurate information. CO monitoring has largely been suspended since the COVID-19 pandemic began, so data for 2020 and 2021 is mainly self-reported. E-Cigarette use should not be recorded in this data item and would not be detected by a CO monitor; however, in practice some mothers may self-report as a smoker if they use e-cigarettes and be incorrectly recorded as a smoker. Likewise, some mothers who do smoke may self-report as a non-smoker and be incorrectly recorded as a non-smoker. Smoking at birth: In 2021, 82% of records had valid data recorded at the Wales level. This was largely due to Hywel Dda health board not supplying any smoking at birth data, while there was only 68% complete data for Cwm Taf Morgannwg. There were also low levels of completeness in 2020 for Hywel Dda (30%), Cwm Taf Morgannwg (70%) and Powys (76%). However, in all years prior to 2020, more than 90% of records had valid data for smoking status at birth, across nearly all health boards.

For more information see the joint statement from Cwm Taf and Abertawe Bro Morgannwg University Health Boards (see weblinks).

More than 90% of records had valid data for both height and weight data items, across all health boards, in most years. The exceptions are: Cwm Taf in 2016 (77%) and in 2019 (88%); and Betsi Cadwaladr in 2019 (89%). Data for BMI is calculated based on heights and weights of the mother; however, records where the weight was below 30kg or above 250kg and/or where height was under 120cm or above 200cm have been excluded from the analysis, as measurements outside of these thresholds are unlikely to be reliable. Also, this analysis only includes mothers whose initial assessment was completed at 14 completed weeks of pregnancy or earlier. This filter is applied as weight measurements for mothers who have initial assessments in the later stages of pregnancy will be affected by the growth of the baby.

Conditions include: puerperal psychosis (severe postnatal depression); bi-polar effective disorder/manic depression; psychosis; psychotic depression; schizophrenia; and other. While more than 90% of records had valid data for this data item, across most health boards, in most years, there are some data quality issues. Only 56% of records for Cardiff and Vale had valid data in 2016 and 88% in Hywel Dda between 2016 and 2018 and in 2020. Data recorded in Betsi Cadwaladr and Cwm Taf Morgannwg appears to have been recorded on a different basis to other health boards, across all years and therefore data for these health boards are excluded from the Wales total figures.
