Data Provider: Welsh Government National Statistics NHS patients treated in a 24-month period (adults and children) by local health board

The National Institute for Health and Care Excellence (NICE) guidance recommends that adults are recalled for check-ups at intervals of 3 months to 24 months depending on the individual’s oral health status. Therefore, when analysing adults treated, the primary statistical measure should be based on adults treated in a 24-month period. This StatsWales cube presents data based on a 24-month period. Data is also shown for children for completeness and this allows for the total number of all patients (adults + children) treated to be measured.

General description

This StatsWales cube presents data for patients treated (adults, children and all patients) in a rolling 24-month period.

Data collection and calculation

The data is derived from dental activity forms submitted for payment and processed by NHS Business Services Authority Dental Services.

‘Patients treated’ counts the number of unique patients that have been treated during the last 24 months; each patient is counted only once even if they have received multiple episodes of care over the period.
The National Institute for Health and Care Excellence (NICE) guidance recommends that adults are recalled for check-ups at intervals of 3 months to 24 months depending on the individual’s oral health status. Therefore, when analysing adults treated, the primary statistical measure should be based on adults treated in a 24-month period.

This StatsWales cube presents data based on a 24-month period. Data is also shown for children for completeness and this allows for the total number of all patients (adults + children) treated to be measured.

The coronavirus (COVID-19) pandemic has had a significant impact on the way dental services have been provided in Wales and therefore affect the data collected from the last quarter of the financial year 2019-20 and the full financial year 2020-21 onwards.

Patients treated within a 24 month period is affected by the change to health board boundaries, following Bridgend moving into the Cwm Taf Morgannwg health board on 1 April 2019. The dataset counts unique individuals receiving dental services in the 24 month period. When an individual has received dental services more than once in the 24 month period in the same health board, only details of the last treatment would be counted in the dataset to avoid double counting. However, because data is collected over a 24 month period where the health board boundary changed, the same individual may be counted in Bridgend’s old health board (Abertawe Bro Morgannwg (ABMU)) and its new health board (Cwm Taf Morgannwg or Swansea Bay) depending on the date of the last treatment. For example, if a patient was treated in Bridgend in February 2019 and again in May 2019, they will be counted in the ABMU data for the March 2019 list but the Cwm Taf Morgannwg data from the June 2019 list. And if a patient was treated at Bridgend in March 2019 and has not visited a dentist since, they will be counted in the ABMU data for the March 2019 list, and the Swansea Bay data from the June 2019 list.
To give a more reflective figure for the percentage of patients treated (total, adults and children), population estimates of the new health boards have been created using additional data of patients treated in Bridgend after 1st April 2019 (sourced from NHS Business Services Authority). For example, data for July-September 2019 shows of the patients treated in Bridgend, 56% received a treatment after 1st April 2019 at Cwm Taf Morgannwg. Therefore, for the 24 months ending September 2019, the denominator for the new health boards is estimated as:
Swansea Bay’s eligible population = Swansea + Neath Port Talbot + ((0.44) * Bridgend)
Cwm Taf Morgannwg’s eligible population = Rhondda Cynon Taf + Merthyr Tydfil + ((0.56) * Bridgend)

Data for the 24 month period ending April 2021 will be the first time period where the boundary issue will not affect the data. Caution is advised when using the data for the time periods which overlap the health board boundary change.

Revisions information

The ONS has revised the mid-year population estimates for the period mid-2012 to mid-2021 using the 2021 Census data. This means that statistics for the percentage of the population who received NHS dental services for the 24 months ending September 2012 to the 24 months ending June 2022 have been revised as of the 07 December 2023 release. Compared against previously published figures for these periods (Wales level), the revised mid-year estimates have resulted in generally marginal percentage increases, with changes ranging from less than 0.1 to 1.2 percentage points. At health board level changes range from a decrease of 0.2 percentage points to an increase of 1.7 percentage points.
Additionally, the 2022 mid-year population estimates have been published by the ONS. The percentage of patients treated data for the 24 months ending 30 September 2022 to the 24 months ending 31 March 2023 have been revised using the 2022 mid-year estimates as of the 7 December 2023 release.

NICE guidance recommends that children are recalled for check-ups at intervals of 3 months to 12 months depending on the individual’s oral health status. Therefore, when analysing children treated, the primary statistical measure should be based on children treated in a 12-month period.
