Coded Prevalence of Mild Cognitive Impairment in General and Neuropsychiatrists Practices in Germany Between 2007 and
1Praxis für Neurologie und Psychiatrie, Berlin, Germany.
Background:
The diagnosis of mild cognitive impairment (MCI) is becoming increasingly important for the medical treatment of dementia.
Objective:
The aim of this study was to investigate whether the coded prevalence of MCI changed in the period from 2007 to 2017 compared to dementia diagnoses.
Methods:
This was a retrospective evaluation of diagnostic data from 432 general practitioner (GP) practices and 53 neuropsychiatrist (NP) practices in Germany based on the Disease Analyzer database (IQVIA). The frequencies with which MCI and dementia were diagnosed in these practices were determined. The frequency with which dementia was diagnosed was included to determine whether the change in the frequency of MCI diagnoses was due to the increase in dementia prevalence.
Results:
It was found that the number of GP practices with patients receiving MCI diagnoses increased from 16% to 46%, while the number of NP practices with patients receiving MCI diagnoses increased from 55% to 75%. Moreover, the study found an increase in the coded prevalence of MCI from 0.4 to 1.9 patients/GP practice and from 6.5 to 11.1 patients/NP practice were observed.
Conclusions:
A growing number of GPs and NPs code MCI with increasing frequency. However, the coding frequency of MCI in 2017 corresponded to less than 10% of its true prevalence. A sharp increase in MCI diagnoses can be expected, along with the establishment of preventive and disease-modifying dementia strategies.
Insights
The diagnosis of mild cognitive impairment (MCI) is increasingly coded by general practitioners and neuropsychiatrists. However, MCI coding in 2017 represented less than 10% of its true prevalence, indicating a significant underdiagnosis.
Area of Science:
- Neurology
- Geriatrics
- Public Health
Background:
- Mild cognitive impairment (MCI) diagnosis is crucial for dementia management.
- Understanding MCI prevalence trends is vital for healthcare planning.
Purpose of the Study:
- To analyze changes in coded MCI prevalence from 2007 to 2017.
- To compare MCI diagnosis trends with dementia diagnoses.
Main Methods:
- Retrospective analysis of diagnostic data from 432 general practitioner (GP) and 53 neuropsychiatrist (NP) practices in Germany.
- Evaluation of coded frequencies for MCI and dementia diagnoses using the IQVIA Disease Analyzer database.
Main Results:
- The proportion of GP practices diagnosing MCI rose from 16% to 46%; NP practices increased from 55% to 75%.
- Coded MCI prevalence increased from 0.4 to 1.9 patients/GP practice and 6.5 to 11.1 patients/NP practice.
Conclusions:
- GPs and NPs are increasingly coding MCI, but current coding frequency remains significantly below true prevalence.
- Anticipate a substantial rise in MCI diagnoses as preventive and disease-modifying dementia strategies develop.
