Objective: To evaluate how the distribution of patients in groups (based on subjective health experience) changes over time and to investigate differences in physical functioning and mental health between these patient groups.

Design: An observational cohort study.

Setting: University medical center.

Background: The Netherlands faces 60% prevalence of chronic conditions by 2040, impacting societal participation and quality of life. Current clinical care inadequately addresses these consequences, and most hospitals do not integrate occupational health in their care.

Objectives: To develop a generic person- and work-oriented medical care model (WMCM) based on real life experiences with work-oriented care and supporting the chronically ill in active societal participation.

Background And Aims: The patient segmentation model based on disease acceptance and perceived control may guide personalized care in inflammatory bowel disease (IBD). We aimed to investigate the external validity of the segmentation model and its consistency over time.

Methods: This is a multicenter longitudinal cohort study of adult IBD patients with questionnaires on disease acceptance and perceived control (6-items, 7-point Likert scale) and health-related quality of life (HRQoL) (Short IBD questionnaire, range 10-70).

Introduction: The treatment landscape for metastatic hormone sensitive prostate cancer (mHSPC) is rapidly evolving. With an abundance of available treatment strategies, selecting the optimal strategy for an individual patient is becoming increasingly challenging. TripleAiM1 aims to evaluate the impact of mHSPC treatments on health-related quality of life (HRQoL) and to provide real-world data insights on diagnostics, treatment strategies, patient subgroups and related healthcare expenditure for mHSPC.

Article Synopsis
  • The concept of health utility in health economics has been widely accepted but lacks a clear, definitive meaning, with existing definitions not aligned with current psychological insights.
  • The paper critiques the traditional definition for focusing too much on decision-making and preferences, suggesting that it does not fully capture the complexities of human psychology involved in health perceptions.
  • A new definition is proposed, framing health utility as the subjective value derived from one's health experiences, which may enhance discussions and provide more accurate measurements in health economics.

Vitality and health-related quality of life are often assessed in older adults. However, these assessments do not provide guidance on support for older adults with different levels of vitality and health-related quality of life. This guidance can be established through segmentation.

Background And Aims: To determine how the health state of ulcerative colitis patients is impacted by their disease, different health state questionnaires are deployed. This study examines to what extent these health state questionnaires determine the same underlying health state concept and to what extent the complementary use of the health state questionnaires has added value for physicians.

Methods: In total, 307 patients were enrolled in this cross-sectional multicenter cohort study.

Many attempted to develop burden of disease rankings for the purpose of resource allocation, priority setting, cost-effectiveness evaluation, and service development in healthcare. As this proved difficult the World Health Organization commissioned expert panels to develop internally consistent burden of disease rankings. Although these rankings provide valuable insight in the biomedical burden of different diseases, they do not yet provide insight in the psychological burden of different diseases experienced and reported by patients on a daily basis.

Background And Aims: Segmentation of patients based on psychological determinants of subjective health may provide new ways to personalized care. The cross-disease segmentation model developed by Bloem & Stalpers discriminates patients based on disease acceptance and perceived control. We aimed to validate the segmentation model, compare segments and evaluate whether segments independently correlate with quality of life in inflammatory bowel disease [IBD].

Background: There is an observable, growing trend toward tailoring support programs - in addition to medical treatment - more closely to individuals to help improve patients' health status. The segmentation model developed by Bloem & Stalpers [Nyenrode Research Papers Series 12:1-22, 2012] may serve as a solid basis for such an approach. The model is focused on individuals' 'health experience' and is therefore a 'cross-disease' model.
