BackgroundRecent reports have suggested declining age-specific incidence rates of dementia in high-income countries over time. Improved education and cardiovascular health in early age have been suggested to be bringing about this effect. The aim of this study was to estimate the age-specific dementia incidence trend in primary care records from a large population in the Netherlands.Methods and findingsA dynamic cohort representative of the Dutch population was composed using primary care records from general practice registration networks (GPRNs) across the country. Data regarding dementia incidence were obtained using general-practitioner-recorded diagnosis of dementia within the electronic health records. Age-specific dementia incidence rates were calculated for all persons aged 60 y and over; negative binomial regression analysis was used to estimate the time trend. Nine out of eleven GPRNs provided data on more than 800,000 older people for the years 1992 to 2014, corresponding to over 4 million person-years and 23,186 incident dementia cases. The annual growth in dementia incidence rate was estimated to be 2.1% (95% CI 0.5% to 3.8%), and incidence rates were 1.08 (95% CI 1.04 to 1.13) times higher for women compared to men. Despite their relatively low numbers of person-years, the highest age groups contributed most to the increasing trend. There was no significant overall change in incidence rates since the start of a national dementia program in 2003 (−0.025; 95% CI −0.062 to 0.011). Increased awareness of dementia by patients and doctors in more recent years may have influenced dementia diagnosis by general practitioners in electronic health records, and needs to be taken into account when interpreting the data.ConclusionsWithin the clinical records of a large, representative sample of the Dutch population, we found no evidence for a declining incidence trend of dementia in the Netherlands. This could indicate true stability in incidence rates, or a balance between increased detection and a true reduction. Irrespective of the exact rates and mechanisms underlying these findings, they illustrate that the burden of work for physicians and nurses in general practice associated with newly diagnosed dementia has not been subject to substantial change in the past two decades. Hence, with the ageing of Western societies, we still need to anticipate a dramatic absolute increase in dementia occurrence over the years to come.

BackgroundCardiovascular prevention programmes are increasingly being offered to older people. To achieve the proposed benefits, adherence is crucial. Understanding the reasons for adherence and non-adherence can improve preventive care.AimTo gain insight into what motivates older people living in the community to partake in a cardiovascular prevention programme, and reasons for subsequent continuation or withdrawal.Design and settingQualitative study of current and former participants of the ongoing ≥6 year PreDIVA (prevention of dementia by intensive vascular care) trial in primary care practices in suburban areas in the Netherlands.MethodSemi-structured interviews were conducted with a purposive sample of 15 participants (aged 76–82 years). Interviews were audiorecorded and analysed by two independent researchers using a thematic approach. Participants were asked about their motivation for participating in the programme, along with the facilitators and barriers to continue doing so.ResultsResponders reported that regular check-ups offered a feeling of safety, control, or being looked after, and were an important motivator for participation. For successful continuation, a personal relationship with the nurse and a coaching approach were both essential; the lack of these, along with frequent changes of nursing staff, were considered to be barriers. Participants considered general preventive advice unnecessary or patronising, but practical support was appreciated.ConclusionTo successfully engage older people in long-term, preventive consultations, the approach of the healthcare provider is crucial. Key elements are to offer regular check-ups, use a coaching approach and to build a personal relationship with the patient.
