[Proactive and structured care for the elderly in primary care]. / Proactieve en gestructureerde zorg voor kwetsbare oudere patiënten in de eerstelijn: Achtergrond, opzet en uitvoering van een screenings- en zorgprogramma.

BACKGROUND: Currently, primary care for the older, vulnerable patient is reactive, fragmented and does not meet patients needs. Given the expected increase of home-dwelling frail elderly people a transition is needed to proactive and integrated care. METHODS: In the described study, we explore two innovative interventions in primary care. First we describe a newly developed screening and monitoring program for frail elderly patients based on routine care information in general practice. Second, we describe a multidisciplinary intervention program by trained nurses for frail elderly patients in general practice. The effectiveness of the interventions is examined in a three-armed, cluster randomized trial, taking place in 58 primary care practices in Utrecht, the Bilt and Maarsenbroek. RESULTS: Three thousand eight patients are included. Primary outcome measure is the impact of the interventions on the daily activities, measured with the Katz questionnaire. Secondary outcomes measures are the quality of life, mortality, recording in a care or nursing home, visit to an emergency room or outpatient unit, recording in the hospital and volunteer caregivers tax.

Measuring longitudinal white matter changes: comparison of a visual rating scale with a volumetric measurement.

BACKGROUND AND PURPOSE: Detection of longitudinal changes in white matter hyperintensities (WMH) by using visual rating scales is problematic. We compared a widely used visual rating scale with a volumetric method to study longitudinal white matter changes. METHODS: WMH were assessed with the visual Scheltens scale and a volumetric method in 100 elderly subjects aged 70-81 years for whom repetitive MR images were available with an interval of 33 (SD, 1.4) months. Reliability was determined by intraclass correlation coefficients. To examine the sensitivity of both the visual and volumetric method, we calculated Spearman rank correlations of WMH ratings and volume measurements with age. RESULTS: Reliability of the visual rating scale was good, whereas reliability of the volumetric measurement was excellent. For baseline measurements of WMH, we found weaker associations between WMH and age when assessed with the visual scale (r = 0.20, P = .045) than with the volumetric method (r = 0.31, P = .002). Longitudinal evaluation of WMH assessments showed regression in 26% of the subjects when analyzed with the visual rating scale against 12% of the subjects when using volumetric measurements. Compared with the visual rating, the correlation between progression in WMH and age was twice as high when using the volumetric measurement (r = 0.19, P = .062 and r = 0.39, P < .001, respectively). CONCLUSION: Volumetric measurements of WMH offer a more reliable, sensitive, and objective alternative to visual rating scales in studying longitudinal white matter changes.

[Role of statins in prevention of stroke and dementia]. / De rol van statinen bij de preventie van beroerte en dementie.

There is accumulating evidence that statins reduce stroke risk, even though total cholesterol is not a risk factor for stroke. The explanation for this discrepancy is subject to discussion. It should be realised that the beneficial effects of statins on stroke risk have only been demonstrated in a select population, i.e. middle-aged men with ischaemic heart disease. Several clinical trials are underway to examine the effects of statins on stroke risk in more characteristic groups of patients who are at increased risk of developing stroke. The results of these studies should be awaited before statins are recommended for the prevention of stroke. Recently it has been reported that statins lower the risk of developing dementia. These conclusions were drawn from two cross-sectional studies. Because of the nature of the studies, only an association between the use of statins and a lower risk of developing dementia was shown, and not a causal relationship. Experimentally-controlled studies have to be designed to investigate the effect of statins on dementia.

Associations between Frailty, Complex Care Needs and Quality of Life in Multi-Morbid Older People.

BACKGROUND: Little is known regarding the complex care needs, level of frailty or quality of life of multi-morbid older patients. OBJECTIVES: The objective of this study was to determine the relationship between frailty, complexity of care and quality of life in multi-morbid older people. DESIGN: Cross-sectional study. SETTING: Thirteen primary care practices in the Netherlands. PARTICIPANTS: 1,150 multi-morbid older people living in the community. MEASUREMENTS: The level of frailty was assessed with the Groningen Frailty Indicator. Complexity of care needs was measured with the Intermed for the Elderly Self-Assessment. Quality of life (QoL) was measured with two items of the RAND-36. RESULTS: In total, 758 out of 1,150 (65.9%) patients were frail, 8.3% had complex care needs, and the mean QoL score was 7.1 (standard deviation 1.2). Correlations between frailty and complexity, frailty and QoL, and complexity of care and QoL were 0.67, -0.51 and -0.52 (all p<0.001) respectively. All patients with complex care needs were frail, but, only 12.5% of the frail patients had complex care needs. Problems at climbing up stairs was associated with higher levels of frailty and complexity of care but with a lower QoL. CONCLUSIONS: Higher levels of frailty and complexity of care are associated with a lower QoL in multi-morbid older people. The results of this study contribute to a better understanding these concepts and are valuable for the development of tailored interventions for older persons in the future.

Increase in periventricular white matter hyperintensities parallels decline in mental processing speed in a non-demented elderly population.

OBJECTIVE: To investigate the influence of deep white matter hyperintensities (DWMH) and periventricular white matter hyperintensities (PVWMH) on progression of cognitive decline in non-demented elderly people. METHODS: All data come from the nested MRI sub-study of the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER). We performed a 3 year follow up study on 554 subjects of the PROSPER study using both repeated magnetic resonance imaging and cognitive testing. Cognitive decline and its dependency on WMH severity was assessed using linear regression models adjusted for sex, age, education, treatment group, and test version when applicable. RESULTS: We found that the volume of PVWMH at baseline was longitudinally associated with reduced mental processing speed (p = 0.0075). In addition, we found that the progression in PVWMH volume paralleled the decline in mental processing speed (p = 0.024). In contrast, neither presence nor progression of DWMH was associated with change in performance on any of the cognitive tests. CONCLUSION: PVWMH should not be considered benign but probably underlie impairment in cognitive processing speed.

Effect of pravastatin on cerebral infarcts and white matter lesions.

The authors examined the effect of pravastatin 40 mg daily on the progression of ischemic brain lesions using repeated brain MRI. After a mean treatment period of 33 months, there was an increase in total ischemic lesion load of 1.1 cm3 (p < 0.001) in the 270 placebo-treated subjects and 1.1 cm3 (p < 0.001) in the 265 pravastatin-treated subjects. There was no difference between the two treatment groups (p = 0.73).

Different progression rates for deep white matter hyperintensities in elderly men and women.

The authors investigated the progression of white matter hyperintensities (WMHs) in a large population of elderly men and women. After 3 years of follow-up, women had accumulated approximately twice as much deep WMH (DWMH) as men. The progression of periventricular WMH was the same for men and women. Gender differences may affect the pathogenesis of DWMH, which in turn may result in different clinical consequences in women.
