[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.

Validity and reliability of the Katz-15 scale to measure unfavorable health outcomes in community-dwelling older people.

OBJECTIVES: To predict the risk of future unfavourable health outcomes in older people it is common to assess the level of both basic and instrumental activities of daily living. To accomplish this, the commonly used Katz-6 and the Lawton IADL questionnaires can be combined to form the 'Modified Katz ADL' scale, also known as the Katz-15 scale. So far, the validity and reliability of the Katz-15 scale is unknown. The objective of the current study is to investigate how well the Katz-15 is able to predict future unfavorable health outcomes and how this is related to the existing Katz-6 scale. DESIGN: We performed a follow-up study using data from a group of 60 year and older participants from a large Dutch clinical trial. PARTICIPANTS: We included 2321 participants in the analysis. The average age of the study population was 74 years and 44% was male. MEASUREMENTS: We studied the relation between the Katz-15 scale and a number of unfavourable health outcomes, such as hospitalization, admission to a nursing home, admission to a home for the aged and death within one year of follow-up. RESULTS: We found the Katz-15 to be both internally consistent and strongly associated with quality of life measures. We observed moderate to strong associations between the Katz-15 and the unfavourable health outcomes All associations studied were stronger for the Katz-15 scale as compared to the Katz-6 scale. CONCLUSION: The results of our study indicate that the Katz-15 scale is able to reliably and validly predict future unfavorable health outcomes. This makes the scale a valuable measure in determining both basic and instrumental activities of daily living.

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.
