Table 2 Target criteria set for each evaluation domain

From: Adapting the definition of multimorbidity – development of a locality-based consensus for selecting included Long Term Conditions

Domain

Target Criteria

Inclusion Criteria

Prevalence

Purpose: to identify high prevalence conditions (that impact a greater number of people)

Estimated condition prevalence (UK 2017)

 >  = 1%

Impact of LTC

Purpose: to identify conditions that have a greater impact on people’s lives

Progressive natural course? (yes/no)

Yes

Impact YLL

Purpose: to identify conditions that are having a greater population-level impact in terms of years of life lost

Rank by volume of YLL (UK, 2017—Source: GBD)

Top 20

Impact YLD

Purpose: to identify conditions that are having a greater population-level impact in terms of years lived in disability

Rank by volume of YLD (UK, 2017—Source: GBD)

Top 20

Prevention and Modifiability

Purpose: to identify conditions that can be prevented, the onset delayed, or improved by modifying risk factors or intervention

Do risk factors play a role in preventing or delaying the onset of the condition? (yes/no)

Yes

Can intervention result in complete resolution? (yes/no)

Yes

Treatment Burden: Utilisation

Purpose: to identify conditions that account for a high-proportion of population-level admitted patient care

Rank by volume of hospital admissions (based on primary diagnosis) (England, 2017/18—Source: HES data, NHSD)

Top 20

Treatment Burden: Medication

Purpose: to identify conditions that have a high treatment burden, particularly in relation to medication burden

Number of first-line, self-administered medications

 >  = 2

Progression to mLTCs

Purpose: to identify conditions that are most likely to be involved in a mLTCs journey

Proportion of people with the condition who have 1 + comorbidities

 > 50%

Impact on younger people: Age at Onset

Purpose: to identify conditions that can present in younger people, as these that are more likely to be the first condition in a multimorbidity pathway

Typical age of onset of the condition

 < 50 years old

Impact on younger people: YLD in younger people (aged 15–49)

Purpose: to identify conditions that have a high population-level impact on years lived with disability, in younger people

Rank by volume of YLD, in people aged 15–49 (UK, 2017—Source: GBD)

Top 20

Data Quality

Purpose: to identify conditions where data quality is of a sufficient level to allow for meaningful data analysis

Level of data quality: Low/Medium/High, based on three main criteria (whether a condition is included in QOF, whether regular/frequent prescriptions are required, whether hospitalisation for the condition is common), in combination with background knowledge on data quality

Medium and High
