Show moreRoom for improvement is present in the treatment of migraine in primary care. However, inviting all patients who receive prescriptions for __2 triptans each month to have an evaluation consultation with their general practitioner (GP), produces insufficient effect on headache outcomes and costs. However, it remains important to stay alert on patients who are candidate for preventive treatment. When discussing the possibility of preventive treatment, GPs should keep in mind possible barriers in patients. Also, GPs have to ask themselves if they do not deny patients a possibly effective treatment because of their own negative ideas towards preventive medication. Also, we learned that when designing pragmatic studies in primary care, there are methodological issues that make it harder to prove the effectiveness of an intervention. First, the outcomes of pragmatic studies in primary care can negatively affected by changes in the behaviour of GPs and patients in the control group. Second, the quality of life outcome measures that are often used in this type of research are harder to validate and to interpret than the more robust outcome measures that are used in clinical trials Show less

Show moreThis thesis describes the PROMODE-study, which investigated in a pragmatic way whether a pro-active approach in primary care by screening for depressive symptoms, followed by an intervention offer to persons of 75 years and over who screened positive, is (cost)effective to detect and relieve suffering from depressive symptoms at old age. We compared two screening methods regarding yield and costs. Furthermore, we found that scores of the 15-item Geriatric Depression Scale were higher when this screening questionnaire was self-administered than when interviewer-administered. In our intervention study, a cluster-randomised controlled trial, we found that the stepped-care intervention program was not (cost)effective compared with usual care in general practice, possibly due to a low uptake of the offered course being the main part of the intervention. In a qualitative study we explored the limiting and motivating factors for accepting course participation. This revealed that most persons were not (yet) prepared to accept the unsolicited intervention offer, although perceived needs to relieve depressive symptoms seemed to largely match the elements of the course. It is discussed that a more selective approach, aimed at high risk-groups and focussing on need for and readiness to accept help, might increase efficiency of a combined screening-intervention program.

Show moreThe aim of this thesis was to study cardiovascular risk management in old age, in order to facilitate the development of age specific guidelines. In part one the current status of cardiovascular prevention in old age is described, including a study into general practitioners__ attitudes and perceived barriers in this respect. The second part explores the incremental value of routine-ECGs for cardiovascular risk management in older persons from the general population, beyond existing information from medical records. The third part focuses on primary prevention, exploring the performance of classic risk factors, and some new biomarkers, in predicting cardiovascular mortality in very old people from the general population. It was concluded that a homocysteine level alone accurately identifies those at high risk of cardiovascular mortality, whereas classic risk factors included in the Framingham risk score do not. Next, in various age strata from age 55 years onwards, the association between blood pressure and mortality was studied. Finally, a systematic review into the diagnostic accuracy of natriuretic peptides for the diagnosis of chronic heart failure in older persons from the general population was performed, followed by a study in a cohort of nonagenarians into the prognostic value of NT-proBNP. A general discussion is provided, including directions for future research. Show less
