Segmentation of health-care consumers: psychological determinants of subjective health and other person-related variables

Outcomes with ibrutinib in patients with chronic lymphocytic leukaemia: Results from the German multicentre REALITY study

OBJECTIVES

To assess treatment adherence, effectiveness and safety outcomes of patients with chronic lymphocytic leukaemia (CLL) receiving ibrutinib in a real-world setting.

METHODS

Patients enrolled in REALITY were ≥18 years with a confirmed diagnosis of CLL and were receiving ibrutinib as a first-line (1L), 2L or ≥3L therapy. Treatment retention, adherence, progression-free survival (PFS), overall survival (OS) and time to next therapy were assessed at 1 and 2 years overall, by typology and by cytogenetic subgroups. PFS and OS were analysed using Kaplan-Meier methods.

RESULTS

Exactly 302 patients were enrolled across 57 sites in Germany, from January 2017 to July 2021. One-year retention rates were 69.9% overall (primary endpoint), 77.9% for 1L patients, and 77.6%/78.8% for high-risk patients with del17p/TP53. At 2 years, PFS/OS rates were 77.8%/90.7% overall (1L, 82.7%/90.4%), and were consistent across cytogenetic subgroups. PFS rates were higher for 1L versus ≥3L patients. Patients with the low-acceptance/low-control typology at baseline were less likely to retain treatment at 1 year versus the high-acceptance/high-control typology. No new safety signals were observed.

CONCLUSIONS

The REALITY study provides further evidence of the effectiveness and safety of ibrutinib in patients with CLL in a real-world setting, particularly in earlier treatment lines.

Exploring adolescent girls and young women's PrEP-user profiles: qualitative insights into differentiated PrEP delivery platform selection and engagement in Cape Town, South Africa

INTRODUCTION

Adolescent girls and young women (AGYW), a priority population for HIV prevention in Africa, show high interest but difficulty in sustained effective use of pre-exposure prophylaxis (PrEP). With ongoing PrEP scale-up focused on increasing access, it is important to understand what influences AGYW's choice of PrEP delivery platforms.

METHODS

The POWER implementation study in Cape Town provided PrEP between 2017 and 2020 to AGYW (16-25 years) from four differentiated delivery platforms: mobile clinic, government facility, courier delivery or community-based youth club. Healthcare providers at government and mobile clinics provided PrEP (initiation and refills) as part of comprehensive, integrated sexual and reproductive health services. Courier and youth club platforms provided light-touch PrEP refill services incorporating rapid HIV self-testing. We conducted in-depth interviews with a purposive sample of AGYW who had ≥3 months of PrEP-use and accessed ≥2 PrEP delivery platforms. The thematic analysis explored AGYW's preferences, decision-making and habits related to PrEP access to inform market segmentation.

RESULTS

We interviewed 26 AGYW (median age 20) PrEP-users between November 2020 and March 2021. AGYW PrEP-users reported accessing different services with, 24 accessing mobile clinics, 17 courier delivery, 9 government health facilities and 6 youth clubs for their PrEP refills. Qualitative findings highlighted four potential behavioural profiles. The "Social PrEP-user" preferred PrEP delivery in peer spaces, such as youth clubs or adolescent-friendly mobile clinics, seeking affirmation and social support for continued PrEP use. The "Convenient PrEP-user" favoured PrEP delivery at easily accessible locations, providing quick (courier) or integrated contraception-PrEP refill visits (mobile and government clinic). The "Independent PrEP-user" preferred PrEP delivery that offered control over delivery times that fit into their schedule, such as the courier service. The "Discreet PrEP-user" highly valued privacy regarding their PrEP use (courier delivery) and avoided delivery options where unintentional disclosure was evident (youth club). Comfort with HIV self-testing had minimal influence on PrEP delivery choice.

CONCLUSIONS

Market segmentation of AGYW characterizes different types of PrEP-users and has the potential to enhance tailored messaging and campaigns to reach specific segments, with the aim of improving sustained PrEP use and HIV prevention benefits.

Audience segmentation of New Zealand cat owners: Understanding the barriers and drivers of cat containment behavior

Free-roaming companion cats have a detrimental impact on the environment and are at risk of harm. Despite these negative impacts, it is the norm in New Zealand (NZ) to allow companion cats to roam freely and only a minority of cat owners practice cat containment. This study firstly sought to identify what factors act as barriers and drivers of NZ owners' participation in cat containment, and secondly whether NZ owners could be segmented into unique audiences based on the factors predicting their cat containment behavior. It was hypothesized that cat owners with greater capability, opportunity, and motivation to perform cat containment would have greater cat containment intentions and behavior. Furthermore, it was expected that at least three segments of cat owners would exist in NZ which differed significantly in the set of capability, opportunity and motivational factors predicting their cat containment behavior. A quantitative online cross-sectional survey of 395 NZ cat owners was conducted, measuring containment intentions and behavior, and capability, opportunity, and motivation to perform cat containment. Results from bivariate correlations and multiple regression demonstrated that capability, opportunity, and motivational factors predicted increased cat containment intentions and behavior. Latent profile analysis identified four distinct segments of cat owners with unique COM profiles; engaged (6%), receptive (17%), ambivalent (48%), and opposed (30%). Validation analysis demonstrated that these groups all differed significantly in their cat containment intentions and behaviors. From these findings theoretically grounded behavior change interventions can be developed to target the causes of non-participation in cat containment for each of the identified cat owner segments, thereby improving the management of free-roaming cats in NZ.

Rethinking the eidos, genos, and diaphora of the health utility concept: a psychological perspective

The notion of utility gained a strong foothold in health economics over the last decades. However, the concept of health utility has not yet been decisively or irrefutably defined and the definitions that exist often do not take into account the current state of psychological literature. This perspective paper shows that the current definition of health utility emphasizes decision-making processes, deploys personal preferences, assumes psychological egoism, and attempts to objectively and cardinally measure utility. However, these foundational axioms that underly the current definition of health utility are not necessarily in concurrence with the current state of psychological literature. Due to these perceived shortcomings of the current health utility definition, it may be beneficial to redefine the concept of health utility in accordance with the current state of psychological literature. In order to develop such a revised definition of health utility the commonly deployed formula (Eidos = Genos + Diaphora) originating from Aristotle's metaphysics is applied. The revised definition of health utility proposed in this perspective paper alludes to health utility as 'the subjective value, expressed in terms of perceived pain or pleasure, that is attributed to the cognitive, affective and conative experience of one's own physical, mental and social health state, which is determined through self-reflection and interaction with significant others'. Although this revised definition does neither replace nor supersede other conceptualizations of health utility, it may serve as a refreshing avenue for further discussion and could, eventually, support policymakers and health economists in operationalizing and measuring health utility in an even more accurate and veracious manner.

Determining the Appropriate Support for Older Adults with Different Levels of Vitality and Health-Related Quality of Life: An Explanatory Study

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. The Subjective Health Experience model segments individuals and indicates support for each segment. By examining how older adults with different levels of vitality and health-related quality of life correspond with each segment and by specifying the indicated support to older adults, guidance can be established. This was examined by administering a questionnaire to 904 older adults and interviewing 8. Analysis was performed using one-way ANOVA and the matrix method. In segment 1, older adults sustained higher levels of vitality and health-related quality of life relative to other segments. They need information and certainty. In segment 2, older adults sustained lower levels of vitality and health-related quality of life relative to segment 1, and higher levels relative to segment 3 or 4. They need planning and structure. In segment 3, older adults sustained lower levels of vitality and health-related quality of life relative to segment 1 or 2, and higher levels relative to segment 4. They need emotive assistance. In segment 4, older adults sustained lower levels of vitality and health-related quality of life relative to other segments. They need personal coaching. As levels of vitality and health-related quality of life correspond with the segments, deploying vitality and health-related quality of life measures together with the model might be beneficial.

Implementation and use of technology-enabled blood pressure monitoring and teleconsultation in Singapore's primary care: a qualitative evaluation using the socio-technical systems approach

BACKGROUND

Telemedicine is becoming integral in primary care hypertension management, and is associated with improved blood pressure control, self-management and cost-effectiveness. This study explored the experiences of patients and healthcare professionals and their perceived barriers and facilitators in implementing and using a technology-enabled blood pressure monitoring intervention with teleconsultation in the Singapore primary care setting.

METHODS

This was a qualitative study embedded within the Primary Technology-Enhanced Care Hypertension pilot trial. Patients were selected purposively and invited to participate by telephone; healthcare professionals involved in the trial were invited to participate by email. Individual semi-structured interviews were conducted in English or Mandarin with thirteen patients and eight healthcare professionals. Each interview was audio-recorded and transcribed verbatim. Data were analyzed inductively to identify emergent themes which were then grouped into the dimensions of the socio-technical systems model to study the interactions between the technical, individual and organizational factors involved in the process.

RESULTS

Several emergent themes were identified. The factors involved in the implementation and use of the intervention are complex and interdependent. Patients and healthcare professionals liked the convenience resulting from the intervention and saw an improvement in the patient-provider relationship. Patients appreciated that the intervention helped form a habit of regular blood pressure monitoring, improved their self-management, and provided reassurance that they were being monitored by the care team. Healthcare professionals found that the intervention helped to manage workload by freeing up time for other urgent matters. Nevertheless, participants highlighted challenges with usability of the equipment and management portal, data access, and some expressed technology anxiety. Participants suggested patient segmentation for the intervention to be more targeted, wished for a more user-friendly equipment and proposed allocating more resources to the intervention.

CONCLUSIONS

The implementation and use of telemedicine for hypertension management can engender various benefits and challenges to patients, healthcare professionals and the healthcare system. Stakeholder feedback gathered on the sociotechnical aspects of the technology should be taken into consideration to guide the design, implementation and evaluation of future telemedicine interventions in primary care.

The Diabetes teleMonitoring of patients in insulin Therapy (DiaMonT) trial: study protocol for a randomized controlled trial

BACKGROUND

The effect of telemedicine solutions in diabetes remains inconclusive. However, telemedicine studies have shown a positive trend in regards to glycemic control. The telemedicine interventions that facilitate adjustment of medication seems to improve glycemic control more effectively. Hence, it is recommended that future telemedicine studies for patients with diabetes include patient-specific suggestions for changes in medicine. Hence, the aim of the trial is to explore the effect of telemonitoring in patients with type 2 diabetes (T2D) on insulin therapy.

METHODS

The trial is an open-label randomized controlled trial with a trial period of 3 months conducted in two sites in Denmark. Patients with T2D on insulin therapy will be randomized (1:1) to a telemonitoring group (intervention) or a usual care group (control). The telemonitoring group will use a continuous glucose monitor (CGM), an insulin pen, an activity tracker, and smartphone applications throughout the trial. Hospital staff will monitor the telemonitoring group and contact the subjects by telephone repeatedly throughout the trial period. The usual care group will use a blinded CGM the first and last 20 days of the trial and will use a blinded insulin pen for the entire period. The primary endpoint will be changed from baseline in CGM time in range (3.9-10.0 mmol/L) 3 months after randomization. Secondary endpoints include change from baseline in glycated hemoglobin (HbA1c), total daily dose, time above range, and time below range 3 months after randomization. Exploratory endpoints include health-related quality of life, diabetes-related quality of life, etc. DISCUSSION: The DiaMonT trial will test a telemonitoring setup including various devices. Such a setup may be criticized, because it is impossible to determine which element(s) add to the potential effect. However, it is not possible and counterproductive to test the elements individually, since it is the full telemedicine setup that is being evaluated. The DiaMonT trial is the first Danish trial to explore the effect of telemonitoring on patients on insulin therapy. Thus, the DiaMonT trial has the potential to form the basis for the implementation of telemedicine for patients with T2D in Denmark.

Exploring Korean Middle- and Old-Aged Citizens’ Subjective Health and Quality of Life

The goal of this research is to investigate the determinants of subjective health and quality of life with a particular focus on middle- and old-aged citizens. Subjective health is an antecedent of quality of life. For both attributes, travel frequency, economic activity, and cultural activity frequency are the main explanatory variables. Korean middle- and old-aged citizen research panel data was used to derive the data; the study periods are 2008, 2010, 2012, 2014, and 2016. The present work used an econometric method to analyze this panel data. The results show that subjective health positively affects quality of life; meanwhile, economic activity positively affects both subjective health and quality of life. It is also found that cultural activity and travel exert inverted U-shape impacts on subjective health and quality of life. The control variables in this research were gender, body mass index, birth year, and personal assets. These results could help guide policy makers in designing more efficient welfare policies for middle- and old-aged citizens.

Differences between expert reported and patient reported burden of disease rankings

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. Since expert reported and patient reported burden of disease could differ, deviations between expert reported and patient reported burden of disease rankings are likely. To explore how these rankings differ, it is important to develop patient reported burden of disease rankings and compare these to expert reported burden of disease rankings. In this study patient reported burden of disease rankings were developed by ranking the subjective health experience of patients. To measure subjective health experience an online questionnaire was administered to a large panel of Dutch citizens. The final sample consisted of 58,490 panel members. This final sample contained 36 diseases and was largely representative of the Dutch population. The data were analysed by using reliability tests, descriptive statistics and Spearman rank-order correlation coefficients. This study shows that expert reported and patient reported burden of disease rankings could differ. Burden of cardiovascular diseases ranks low on patient reported burden of disease rankings, while it ranks higher on expert reported burden of disease rankings. Burden of psychiatric diseases and gastrointestinal diseases ranks high on patient reported burden of disease rankings, while it ranks lower on expert reported burden of disease rankings. Burden of pain diseases ranks high on patient reported burden of disease rankings, while it is still overlooked in expert reported burden of disease rankings. This study suggests that it can be beneficial to develop and utilize patient reported burden of disease rankings in addition to the already existing expert reported burden of disease rankings in order to establish a more comprehensive perspective on burden of disease. This could improve decision-making on resource allocation, priority setting, cost-effectiveness evaluation, and service development in healthcare.

Acceptance and Perceived Control are Independently Associated With Quality of Life in Inflammatory Bowel Disease: Introduction of a New Segmentation Model

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].

METHODS

A cross-sectional study of adult IBD patients was performed with questionnaires on quality of life [32-item inflammatory bowel disease questionnaire], acceptance and perceived control [six items with 7-point Likert scale]. Four segments were formed [cut-off > 5]: [I] high acceptance, high control; [II] high acceptance, low control [III]; low acceptance, high control and; [IV] low acceptance, low control.

RESULTS

We included 686 patients. The acceptance and perceived control scales were unidimensionally structured and internally consistent. Segments differed significantly in age, smoking behaviour, diagnosis, disease duration, extra-intestinal manifestations, IBD medication, clinical disease activity and quality of life. High acceptance (standardized beta coefficient [ß] 0.25, p < 0.001), high perceived control [ß 0.12, p < 0.001] or both [ß 0.53, p < 0.001], were associated with a significantly better health-related quality of life compared with low acceptance and low perceived control. Sociodemographic and clinical factors explained 25% of the variance in quality of life. The explained variance significantly increased to 45% when the patients' segment was added to the model [ΔR2 20%, p < 0.001].

CONCLUSIONS

The segmentation model based on disease acceptance and perceived control is valid in IBD patients and discriminates different segments that correlate independently with quality of life. This may open new strategies for patient care.

Differences in tobacco smoking status in segments of the Australian population

Purpose

The purpose of this study is to identify correlates of tobacco smoking behaviour across various socio-demographic segments of the Australian population.

Design/methodology/approach

Data from two nationally representative, probability samples of persons 18 and over, surveyed by the Australian Bureau of Statistics in 2001 and 2017–2018 were analysed using multinomial logistic regression.

Findings

Overall, the prevalence of current smokers declined from 24.3 to 15%. More than half of the population had never smoked. The prevalence of ex-smokers increased slightly to 30%. Prevalence of current smoking was higher among older age groups and among those with lower educational achievement, lower income, living in a disadvantaged area and experiencing increasing stress. Females were more likely than males to be never-smokers. Males were more likely than females to be current smokers.

Research limitations/implications

The findings are based on two cross-sectional surveys conducted 17 years apart. It is not possible to draw any conclusions about the actual trajectories of the changes in the values reported or any correlations between those trajectories. Nor is it possible to make any meaningful forecasts about likely future trends in smoking status in these various segments based on these data sets. The classifications used in the surveys generate some heterogeneous groups, which can obscure important differences among respondents within groups. Data are all self-reported, and there is no validation of the self-reported smoking status. This might lead to under-reporting, especially in a community where tobacco smoking is no longer a majority or even a popular habit. Because the surveys are so large, virtually, all the findings are statistically significant. However, the increasing preponderance of never-smokers in many categories might mean that never-smokers could come to dominate the data.

Practical implications

The findings from this paper will help tobacco-control policy-makers to augment whole-of-community initiatives with individual campaigns designed to be more effective with particular socio-demographic segments. They will also assist in ensuring better alignment between initiatives addressing mental health and tobacco smoking problems facing the community.

Originality/value

The examination of smoking behaviour among individual population sub-groups, chosen by the authors, is commonplace in the literature. This paper uses data from two large surveys to model the whole, heterogeneous population, measured at two different points in time.
