360° Diagnostic Tool to Personalize Lifestyle Advice in Primary Care for People With Type 2 Diabetes: Development and Usability Study.

BACKGROUND: Various multifaceted factors need to be addressed to improve the health and quality of life of people with type 2 diabetes (T2D). Therefore, we developed a web-based decision support tool that comprises a more holistic diagnosis (including 4 domains: body, thinking and feeling, behavior, and environment) and personalized advice. This 360° diagnostic tool enables people with T2D and health care professionals at the general practice to obtain an overview of the most important T2D-related issues and, subsequently, determine the most suitable intervention for the person with T2D. OBJECTIVE: This study aimed to describe the systematic and iterative development and evaluation of the web-based 360° diagnostic tool. METHODS: We defined the requirements for the web-based 360° diagnostic tool based on previously developed tools, a literature review, and inputs from a multidisciplinary team of experts. As part of the conceptualization, we defined 3 requirements: diagnostics; feedback; and advice, consultation, and follow-up. Next, we developed and designed the content for each of these requirements. We evaluated the diagnostic part of the tool (ie, measurement instruments and visualization) with a qualitative design, in a usability study with a think-aloud strategy and interview questions, among 8 people with T2D at a Dutch general practice. RESULTS: For each of the 4 domains, specific parameters and underlying elements were selected, and measurement instruments (including clinical data and questionnaires) were chosen. Cutoff values were defined to identify high-, middle-, and low-ranking scores, and decision rules were developed and implemented using R scripts and algorithms. A traffic light color visual design was created (profile wheel) to provide an overview of the scores per domain. We mapped the interventions that could be added to the tool and developed a protocol designed as a card deck with motivational interview steps. Furthermore, the usability study showed that people with T2D perceived the tool as easy to use, useful, easy to understand, and insightful. CONCLUSIONS: Preliminary evaluation of the 360° diagnostic tool by experts, health care professionals, and people with T2D showed that the tool was considered relevant, clear, and practical. The iterative process provided insights into the areas of improvement, which were implemented. The strengths, shortcomings, future use, and challenges are also discussed.

A qualitative study into the perspectives of clients on shared decision-making as a method to support return to work.

BACKGROUND: Being able to participate in work is an important determinant of health. Therefore, reintegration professionals provide support to clients to return to work (RTW). Since RTW has a significant impact on a client's life, it is preferred that clients are involved in the decision-making process of RTW. A method to do so, is shared decision-making (SDM), involving the following steps: collaborating as a team, explaining to clients that they can be part of the decision-making process, setting a shared goal, presenting and discussing choice options, and making a shared decision. OBJECTIVE: We explored how clients experience and prefer these SDM steps in their current and ideal interaction with professionals. METHODS: We performed semi-structured interviews with fourteen clients receiving support in their RTW process from four different municipalities. RESULTS: Clients emphasised the importance of collaborating as team. None of the clients reported having been told that they could be part of the decision-making process, or discussed a shared goal with a professional, which they would prefer. Some clients were presented choice options. When choice options were discussed, frequently only the negative aspects of choice options were explained by the professional. A great number of clients experienced that shared decisions were made, but based this on the shared effort made by the client and professional to RTW. CONCLUSIONS: Clients generally wish to cooperate and participate in the decision-making process, but their ability to do so is limited due to not being fully involved in the SDM steps.

REACH Worker Exposure Assessments: Ensuring Meaningful Health Risk Communication.

OBJECTIVES: Within the chemical legislation, REACH was implemented in order to improve safe working conditions with hazardous substances. Literature and real-life experiences by those concerned have shown that there are still gaps with a need for improved risk communication. This study elaborated on how information provided by REACH is understood and acted on by down- and upstream users, and how it can be further improved. METHODS: An extensive literature study including 21 studies and 13 tools was carried out. The outcomes were discussed and further supplemented by means of 18 interviews concerning 37 internal safety and REACH documents to build six different use cases representing different Dutch downstream companies. For the upstream perspective also 2 sector organizations and 2 registrants were interviewed. Three online workshops were organized in order to share insights and gather input on international recognition, potential suggestions and further recommendations with 30 participants from nine different EU countries. RESULTS: Although the methods to collect the data differed between the different stages of the study, the general results from all three stages elucidated similar themes in the data and each of the stages used the results from the previous stage as a starting point. Recurring themes concerned the (i) complexity of documents, (ii) deficiencies as experienced by SMEs in REACH, (iii) feedback and responsibilities in the supply chain, and (iv) the cooperation between REACH and OSH. DISCUSSION: The study at hand revealed that even though there are currently several activities to improve communication on safe-use of chemicals, communication on safe-use in the scope of REACH should be improved. This includes e.g. the future involvement of actual end-users in activities and development related to communication of safe-use information in the scope of REACH including feedback, less complicated and complex documents and clear communication concerning legislations and updates of documents. Furthermore, the issues recognized in the Netherlands are mostly also recognized by international workshop participants, thereby indicating international benefits in various areas by means of improved communication. CONCLUSIONS: The study confirmed that many of our generic conclusions were already part of the shared knowledge in the REACH community, but that it is very valuable that this knowledge has been explicated, validated and reported in a structured way in the present project. Besides uncovering some crucial aspects that offer potential improvements regarding risk communication, this study offers possible solutions and next steps to be taken.

Predictors of the Acceptance of an Electronic Coach Targeting Self-management of Patients With Type 2 Diabetes: Web-Based Survey.

BACKGROUND: Type 2 diabetes (T2D) is a lifestyle-related disease whose prevalence increases with age. Diabetes self-management through mobile health (mHealth) apps enables patients with T2D to improve their health. According to the Technology Acceptance Model (TAM), technology acceptance (ie, intended use) is necessary to ensure mHealth can be implemented successfully. Therefore, the specific acceptance requirements of patients with T2D should be considered. OBJECTIVE: This cross-sectional study aims to examine the extent to which different TAM predictors are associated with the acceptance of a diabetes app including an electronic coach (eCoach; Iris app) among patients with T2D. METHODS: Using a web-based survey, data on 92 patients with T2D (mean age 62.76 years, SD 8.29 years) were collected. Acceptance of the Iris app with the TAM predictors (ie, perceived usefulness, perceived ease of use, social influence, perceived self-efficacy, perceived security, prior usage experience, perceived health, and propensity of data/information sharing) was assessed. Further, control variables (ie, gender, age, education, ethnicity, household, BMI, amount of years with diabetes, diabetes-related complaints, and medication use) were assessed. RESULTS: Multiple linear regression analyses showed that acceptance of the Iris app was positively associated with perceived usefulness (ß=.57, P<.001), social influence (subjective norm; ß=.20, P=.004), and willingness to share data (ß=.25, P<.001). In addition, acceptance regarding the Iris app was higher among patients with T2D with overweight (ß=.23, P=.01) or obese BMI (ß=.21, P=.01). The model explained 75.8% of the variance in the acceptance of the Iris app by patients with T2D. In addition, perceived usefulness of the Iris app was positively related to perceived ease of use (ß=.32, P<.001), subjective norm (ß=.26, P=.004), perceived control (ß=.19, P=.03), willingness to share data (ß=.20, P=.01) regarding the Iris app, and perceived security regarding general use of apps/smartphone/internet (ß=.15, P=.04). The model explained 58.2% of the variance in patients' perceived usefulness about the Iris app. CONCLUSIONS: Among patients with T2D, the belief that the use of the Iris app is helpful/beneficial, the willingness to share their Iris app data, and others' approval of using this app can stimulate the acceptance of this app. In addition, the belief that the use of (health) apps is reliable and secure, the belief that the use of the Iris app is easy to use, a higher perceived capability and personal control with using this app, the willingness to share their Iris app data, and others' approval of using this app can stimulate the perceived usefulness of such an app. These TAM predictors explained a high variance in acceptance and perceived usefulness of the Iris app. Implications for practice are addressed.

The Effect of a Lifestyle Intervention on Type 2 Diabetes Pathophysiology and Remission: The Stevenshof Pilot Study.

Although lifestyle interventions can lead to diabetes remission, it is unclear to what extent type 2 diabetes (T2D) remission alters or improves the underlying pathophysiology of the disease. Here, we assess the effects of a lifestyle intervention on T2D reversal or remission and the effects on the underlying pathology. In a Dutch primary care setting, 15 adults with an average T2D duration of 13.4 years who were (pharmacologically) treated for T2D received a diabetes subtyping ("diabetyping") lifestyle intervention (DLI) for six months, aiming for T2D remission. T2D subtype was determined based on an OGTT. Insulin and sulphonylurea (SU) derivative treatment could be terminated for all participants. Body weight, waist/hip ratio, triglyceride levels, HbA1c, fasting, and 2h glucose were significantly improved after three and six months of intervention. Remission and reversal were achieved in two and three participants, respectively. Indices of insulin resistance and beta cell capacity improved, but never reached healthy values, resulting in unchanged T2D subtypes. Our study implies that achieving diabetes remission in individuals with a longer T2D duration is possible, but underlying pathology is only minimally affected, possibly due to an impaired beta cell function. Thus, even when T2D remission is achieved, patients need to continue adhering to lifestyle therapy.

Shared decision making from reintegration professionals' perspectives to support return to work: a qualitative study.

BACKGROUND: Work participation is an important determinant of public health; being unemployed leads to a decrease in an individual's health. In the Netherlands, people with a work disability can apply for disability benefits, in which people also receive support to return to work (RTW). A method, currently used in the medical sector, that can include both the perspective of the reintegration professional and of the individual in the process of RTW, is shared decision making (SDM). In this article we explore to what extent reintegration professionals currently use SDM, and to what extent they prefer to use SDM in their ideal interaction with clients. METHODS: We performed semi-structured interviews with fourteen reintegration professionals from four different municipalities. The transcripts were coded according to content analysis, applying open and axial coding. RESULTS: Reintegration professionals emphasised the importance of having a good relationship with clients, of building trust and collaborating as a team. They did not inform their clients that they could be part of the decision-making process, or discussed a shared goal. Although professionals did emphasise the importance of aligning their approach with the preferences of the client and though they tried to offer some choice options, they did not mention available options, discussed the pros and cons of these options or evaluated decisions with their clients. Furthermore, they did not mention any of these aspects in their ideal interaction with clients. CONCLUSIONS: SDM has a potential value, because all professionals underline the importance of having an alliance with clients, collaborating as a team, and striving to align their approach with the preferences of the client. However, professionals currently perform a limited set of SDM steps. Additional knowledge and skills are needed for both reintegration professionals and municipalities so that professionals can consider and reflect on the value of using SDM, or SDM steps, in supporting RTW. Providing clients with knowledge and skills seems necessary to facilitate both self-management and SDM.

Health outcomes and experiences of direct-to-consumer high-intensity screening using both whole-body magnetic resonance imaging and cardiological examination.

BACKGROUND: Alongside a clinical and research setting, whole body magnetic resonance imaging (WB-MRI) is increasingly offered as a direct-to-consumer screening service. Data is needed on the clinical relevance of findings and associated psychological impact of such screening. Therefore, we conducted a prospective follow-up study to provide insight in the effectiveness and psychological impact of direct-to-consumer screening using both WB-MRI and cardiological examination. METHODS AND FINDINGS: The study population consisted of 3603 voluntary, primarily middle-aged participants who underwent commercial WB-MRI and cardiological screening at one of 6 study clinics in Germany or the Netherlands between July 2014 and March 2016. MRI investigation consisted of directed scans of the brain, neck, abdomen and pelvis. Cardiovascular examination included pulmonary function, resting electrocardiogram, transthoracic echocardiogram and a bicycle exercise stress test. Findings were assessed by experienced radiologists and cardiologists. In addition, participants were inquired about several (psychological) domains, including the expectations and consequences of the screening procedure. Out of 3603 individuals, 402 (11.2%) demonstrated abnormal MRI (n = 381) and/or cardiological findings (n = 79) for which they were advised to undergo further consultation <3 months in regular healthcare. In 59.1% of cases of abnormal MRI findings which were consulted, fully completed consultations were available in 87.1%. After consultation, 77.6% of initial MRI outcomes were adopted. In 40.9% of cases of abnormal MRI findings, recommendations for consultation were not adhered to during the study period. 71.1% of adopted MRI-findings required treatment or monitoring, including 19 malignancies. For abnormal cardiological findings, 70.9% of cases were consulted in regular healthcare. Of these, 91.1% had a completed follow-up procedure of which 72.5% of initial findings were adopted and 83.8% of these findings required treatment or monitoring. The most frequently reported psychological consequences of the screening procedure were getting reassurance (72.0%) and insight into one's own health status (83.0%). 5.0% reported to feel insecure about their health and 6.2% worried more about their health as a consequence of screening. Main limitations of the study were considered the telephonic follow-up of referred clients and the heterogeneity of screening equipment and assessment of radiologists and cardiologists. CONCLUSIONS: Direct-to-consumer screening using whole-body MRI and cardiological testing is feasible and effective for the detection of clinically relevant and treatable abnormalities. Psychological harm was not frequently reported in study participants.

A Self-management Approach for Dietary Sodium Restriction in Patients With CKD: A Randomized Controlled Trial.

RATIONALE & OBJECTIVE: Patients with chronic kidney disease (CKD) are particularly sensitive to dietary sodium. We evaluated a self-management approach for dietary sodium restriction in patients with CKD. STUDY DESIGN: Randomized controlled trial. SETTING & PARTICIPANTS: Nephrology outpatient clinics in 4 Dutch hospitals. 99 adults with CKD stages 1 to 4 or a functioning (estimated glomerular filtration rate≥25mL/min/1.73m2) kidney transplant, hypertension, and sodium intake>130mmol/d. INTERVENTION: Routine care was compared with routine care plus a web-based self-management intervention including individual e-coaching and group meetings implemented over a 3-month intervention period, followed by e-coaching over a 6-month maintenance period. OUTCOMES: Primary outcomes were sodium excretion after the 3-month intervention and after the 6-month maintenance period. Secondary outcomes were blood pressure, proteinuria, costs, quality of life, self-management skills, and barriers and facilitators for implementation. RESULTS: Baseline estimated glomerular filtration rate was 55.0±22.0mL/min/1.73m2. During the intervention period, sodium excretion decreased in the intervention group from 188±8 (SE) to 148±8mmol/d (P<0.001), but did not change significantly in the control group. At 3 months, mean sodium excretion was 24.8 (95% CI, 0.1-49.6) mmol/d lower in the intervention group (P=0.049). At 3 months, systolic blood pressure (SBP) decreased in the intervention group from 140±3 to 132±3mm Hg (P<0.001), but was unchanged in the control group. Mean difference in SBP across groups was-4.7 (95% CI, -10.7 to 1.3) mm Hg (P=0.1). During the maintenance phase, sodium excretion increased in the intervention group, but remained lower than at baseline at 160±8mmol/d (P=0.01), while it decreased in the control group from 174±9 at the end of the intervention period to 154±9mmol/d (P=0.001). Consequently, no difference in sodium excretion between groups was observed after the maintenance phase. There was no difference in SBP between groups after the maintenance phase. LIMITATIONS: Limited power, postrandomization loss to follow-up, Hawthorne effect, lack of dietary data, short-term follow-up. CONCLUSIONS: A coaching intervention reduced sodium intake at 3 months. Efficacy during the maintenance phase was diminished, possibly due to inadvertent adoption of the intervention by the control group. FUNDING: Grant funding from the Netherlands Organization for Health Research and Development and the Dutch Kidney Foundation. TRIAL REGISTRATION: Registered at ClinicalTrials.gov with study number NCT02132013.

From Diabetes Care to Diabetes Cure-The Integration of Systems Biology, eHealth, and Behavioral Change.

From a biological view, most of the processes involved in insulin resistance, which drives the pathobiology of type 2 diabetes, are reversible. This theoretically makes the disease reversible and curable by changing dietary habits and physical activity, particularly when adopted early in the disease process. Yet, this is not fully implemented and exploited in health care due to numerous obstacles. This article reviews the state of the art in all areas involved in a diabetes cure-focused therapy and discusses the scientific and technological advancements that need to be integrated into a systems approach sustainable lifestyle-based healthcare system and economy. The implementation of lifestyle as cure necessitates personalized and sustained lifestyle adaptations, which can only be established by a systems approach, including all relevant aspects (personalized diagnosis and diet, physical activity and stress management, self-empowerment, motivation, participation and health literacy, all facilitated by blended care and ehealth). Introduction of such a systems approach in type 2 diabetes therapy not only requires a concerted action of many stakeholders but also a change in healthcare economy, with new winners and losers. A "call for action" is put forward to actually initiate this transition. The solution provided for type 2 diabetes is translatable to other lifestyle-related disorders.

Variation in intrapartum referral rates in primary midwifery care in the Netherlands: a discrete choice experiment.

OBJECTIVE: in midwife-led care models of maternity care, midwives are responsible for intrapartum referrals to the obstetrician or obstetric unit, in order to give their clients access to secondary obstetric care. This study explores the influence of risk perception, policy on routine labour management, and other midwife related factors on intrapartum referral decisions of Dutch midwives. DESIGN: a questionnaire was used, in which a referral decision was asked in 14 early labour scenarios (Discrete Choice Experiment or DCE). The scenarios varied in woman characteristics (BMI, gestational age, the preferred birth location, adequate support by a partner, language problems and coping) and in clinical labour characteristics (cervical dilatation, estimated head-to-cervix pressure, and descent of the head). SETTING: primary care midwives in the Netherlands. PARTICIPANTS: a systematic random selection of 243 practicing primary care midwives. The response rate was 48 per cent (117/243). MEASUREMENTS: the Impact Factor of the characteristics in the DCE was calculated using a conjoint analysis. The number of intrapartum referrals to secondary obstetric care in the 14 scenarios of the DCE was calculated as the individual referral score. Risk perception was assessed by respondents׳ estimates of the probability of eight birth outcomes. The associations between midwives׳ policy on management of physiological labour, personal characteristics, workload in the practice, number of midwives in the practice, and referral score were explored. FINDINGS: the estimated head-to-cervix pressure and descent of the head had the largest impact on referral decisions in the DCE. The median referral score was five (range 0-14). Estimates of probability on birth outcomes were predominantly overestimating actual risks. Factors significantly associated with a high referral score were: a low estimated probability of a spontaneous vaginal birth (p=0.007), adhering to the active management policy Proactive Support of Labour (PSOL) (p=0.047), and a practice situated in a rural area or small city (p=0.016). KEY CONCLUSIONS: there is considerable variation in referral decisions among midwives that cannot be explained by woman characteristics or clinical factors in early labour. A realistic perception of the possibility of a spontaneous vaginal birth and adhering to expectant management can contribute to the prevention of unwarranted medicalisation of physiological childbirth. IMPLICATIONS FOR PRACTICE: awareness of variation in referrals and the associated midwife-related factors can stimulate midwives to reflect on their referral behavior. To diminish unwarranted variation, high quality research on the optimal management of a physiological first stage of labour should be performed.

[Reasons for having oneself vaccinated against HPV: implications for the future provision of information]. / Redenen om zich te laten vaccineren tegen HPV: implicaties voor toekomstige informatievoorziening.

OBJECTIVE: To examine which factors determined the participation in HPV vaccination programme in 2009 and 2010. DESIGN: Retrospective cross-sectional study. METHOD: Random samples of Dutch girls who had been invited for the HPV vaccination programme in 2009 and 2010, as well as their mothers, were drawn from an Internet panel. Data were gathered by means of a web-based questionnaire. RESULTS: The questionnaire was filled out by 243 girls and 511 mothers from cohort 2009, and by 225 girls and 250 mothers from cohort 2010. In both cohorts, the following factors were related to HPV vaccination: perceived susceptibility for cervical cancer, general opinion about the vaccine, anticipated feelings of regret about the decision made, specific beliefs (e.g. about the protective effects of the vaccine), trust in responsible authorities, perceived opinion of others about the vaccination and their HPV vaccination participation, the degree to which vaccination is taken for granted and the extent to which the decision to have oneself vaccinated is unambiguously perceived. In both cohorts, these factors explained a large and significant part of the variation in HPV vaccination; namely, 89% and 81% of the girls and 94% and 82% of the mothers from the cohorts in 2009 and 2010, respectively. CONCLUSION: This study provides insight into the reasons behind the disappointing participation in the HPV vaccination programme. In order to increase HPV vaccination uptake, future communication should provide balanced information about facts and opinions, and advantages and disadvantages of the vaccination. There should also be room for uncertainty in the choice whether or not to have oneself vaccinated.

Determinants of HPV vaccination intentions among Dutch girls and their mothers: a cross-sectional study.

BACKGROUND: The Dutch government recently added universal Human Papilloma Virus (HPV) vaccination for 12-year-old girls to the existing national immunization program. The participation rate for the initial catch-up campaign for girls aged 13 to 16 years in 2009 was lower (47%) than expected (70%). To inform future HPV information campaigns, this paper examines the social and psychological determinants of the HPV vaccination intentions of girls aged 13 to 16 years and their mothers who were targeted by the Dutch catch-up campaign of 2009. METHODS: A random sample of girls and their mothers was chosen from the Dutch vaccination register and received a letter inviting them to participate (n = 5,998 mothers and daughters). In addition, a random sample was recruited via an online panel by a marketing research company (n = 650 mothers; n = 350 daughters). Both groups were asked to complete a web-based questionnaire with questions on social demographic characteristics, social-psychological factors and HPV vaccination intention. Backward linear regression analyses were conducted to examine which social-psychological factors were most dominantly associated with vaccination intention. RESULTS: Data from 952 mothers (14%) and 642 daughters (10%) were available for the intended analyses. The contribution of social demographic variables to the explained variance of HPV vaccination intention was small but significant for mothers (ΔR² = .01; p = .007), but not significant for daughters (ΔR² = .02; p = .17) after controlling for HPV vaccination uptake and the sample. In addition, social-psychological determinants largely contributed to the explained variance of HPV vaccination intention of mothers (ΔR² = .35; p < .001) and daughters (ΔR² = .34; p < .001). Attitudes, beliefs, subjective norms and habit strength were significantly associated with participants' HPV vaccination intentions. CONCLUSIONS: Because of the large contribution of social-psychological variables to the explained variance of HPV vaccination intentions among the mothers and daughters, future communication strategies targeting HPV vaccination uptake should address attitudes, beliefs, subjective norms and habit strength. There is a need for longitudinal research to confirm the causality of the association between these determinants and HPV vaccination behavior indicated by this study.

Spontaneously published illness stories on a website for young women with breast cancer: do writers and themes reflect the wider population?

This study examined writer characteristics and themes written about in a set of 167 spontaneously published stories on a Dutch website for young women with breast cancer. The stories were coded for 6 disease characteristics and 16 themes. Coding results were compared with the characteristics of young women with breast cancer in a hospital cancer register and to the frequency of problems among young breast cancer patients participating in quantitative studies. We found that writer characteristics were diverse. Yet, logistic regression showed that women were more likely to be a writer if they were diagnosed at a younger age (OR 0.82; 95% CI (0.78, 0.85)), underwent a mastectomy (OR 4.63; 95% CI (2.59, 8.26)), or were in the first treatment period (OR 2.83; 95% CI (1.44, 5.58)). All 16 themes were present in the stories, but some themes were addressed less often than their frequency among participants of quantitative studies suggested. The findings indicate that a set of spontaneously published stories might not completely reflect the characteristics and themes of the wider population of young women with breast cancer. Websites with spontaneously published stories should inform readers about this.

Validity and Reliability of the eHealth Analysis and Steering Instrument.

BACKGROUND: eHealth services can contribute to individuals' self-management, that is, performing lifestyle-related activities and decision making, to maintain a good health, or to mitigate the effect of an (chronic) illness on their health. But how effective are these services? Conducting a randomized controlled trial (RCT) is the golden standard to answer such a question, but takes extensive time and effort. The eHealth Analysis and Steering Instrument (eASI) offers a quick, but not dirty alternative. The eASI surveys how eHealth services score on 3 dimensions (ie, utility, usability, and content) and 12 underlying categories (ie, insight in health condition, self-management decision making, performance of self-management, involving the social environment, interaction, personalization, persuasion, description of health issue, factors of influence, goal of eHealth service, implementation, and evidence). However, there are no data on its validity and reliability. OBJECTIVE: The objective of our study was to assess the construct and predictive validity and interrater reliability of the eASI. METHODS: We found 16 eHealth services supporting self-management published in the literature, whose effectiveness was evaluated in an RCT and the service itself was available for rating. Participants (N=16) rated these services with the eASI. We analyzed the correlation of eASI items with the underlying three dimensions (construct validity), the correlation between the eASI score and the eHealth services' effect size observed in the RCT (predictive validity), and the interrater agreement. RESULTS: Three items did not fit with the other items and dimensions and were removed from the eASI; 4 items were replaced from the utility to the content dimension. The interrater reliabilities of the dimensions and the total score were moderate (total, κ=.53, and content, κ=.55) and substantial (utility, κ=.69, and usability, κ=.63). The adjusted eASI explained variance in the eHealth services' effect sizes (R(2) =.31, P<.001), as did the dimensions utility (R(2) =.49, P<.001) and usability (R(2) =.18, P=.021). Usability explained variance in the effect size on health outcomes (R(2) =.13, P=.028). CONCLUSIONS: After removing 3 items and replacing 4 items to another dimension, the eASI (3 dimensions, 11 categories, and 32 items) has a good construct validity and predictive validity. The eASI scales are moderately to highly reliable. Accordingly, the eASI can predict how effective an eHealth service is in regard to supporting self-management. Due to a small pool of available eHealth services, it is advised to reevaluate the eASI in the future with more services.

Is the impact of hospital performance data greater in patients who have compared hospitals?

BACKGROUND: Public information on average has limited impact on patients' hospital choice. However, the impact may be greater in consumers who have compared hospitals prior to their hospital choice. We therefore assessed whether patients who have compared hospitals based their hospital choice mainly on public information, rather than e.g. advice of their general practitioner and consider other information important than patients who have not compared hospitals. METHODS: 337 new surgical patients completed an internet-based questionnaire. They were asked whether they had compared hospitals prior to their hospital choice and which factors influenced their choice. They were also asked to select between four and ten items of hospital information (total: 41 items) relevant for their future hospital choice. These were subsequently used in a hospital choice experiment in which participants were asked to compare hospitals in an Adaptive Choice-Based Conjoint analysis to estimate which of the hospital characteristics had the highest Relative Importance (RI). RESULTS: Patients who have compared hospitals more often used public information for their hospital choice than patients who have not compared hospitals (12.7% vs. 1.5%, p < 0.001). However, they still mostly relied on their own (47.9%) and other people's experiences (31%) rather than to base their decision on public information. Both groups valued physician's expertise (RI 20.2 [16.6-24.8] in patients comparing hospitals vs. 16.5 [14.2-18.8] in patients not comparing hospitals) and waiting time (RI 15.1 [10.7-19.6] vs. 15.6 [13.2-17.9] respectively) as most important public information. Patients who have compared hospitals assigned greater importance to information on wound infections (p = 0.010) and respect for patients (p = 0.022), but lower importance to hospital distance (p = 0.041). CONCLUSION: Public information has limited impact on patient's hospital choice, even in patients who have actually compared hospitals prior to hospital choice.

E-health applications and services for patient empowerment: directions for best practices in The Netherlands.

OBJECTIVE: E-health may enable the empowerment process for patients, particularly the chronically ill. However, e-health is not always designed with the requirements of patient empowerment in mind. Drawing on evidence-based e-health studies, we propose directions for best practices to develop e-health that promotes patient empowerment. METHODS: The concept of patient empowerment in the Dutch setting is discussed first. The prerequisites for patient empowerment are then described and translated into empowerment areas relevant to e-health. MATERIALS: We reviewed Dutch e-health studies that provide insights into what works, and what does not, in e-health. RESULTS: On the basis of the lessons learned from the studies, we propose directions for best practices to develop e-health that promotes patient empowerment. These directions cover various aspects, such as the design and implementation of e-health, its information content and usability, awareness, and acceptance. The studies also indicate the difficulty of establishing that e-health is really dedicated to patient empowerment. CONCLUSIONS: Despite the body of knowledge about patient empowerment, as well as the technological visibility of e-health, evidence for best practices in general and for patient empowerment in particular is scarce. We call for a more systematic evaluation of e-health for patient empowerment and more reliable evidence. Beyond the organizational and technical issues involved in e-health, there is also a need to demonstrate its practical benefits to patients. The Netherlands is active in developing sustainable e-health. National initiatives are now in place to support the processes with the aim of establishing the required evidence-based best practices.

How breast cancer patients want to search for and retrieve information from stories of other patients on the internet: an online randomized controlled experiment.

BACKGROUND: Other patients' stories on the Internet can give patients information, support, reassurance, and practical advice. OBJECTIVES: We examined which search facility for online stories resulted in patients' satisfaction and search success. METHODS: This study was a randomized controlled experiment with a 2x2 factorial design conducted online. We facilitated access to 170 stories of breast cancer patients in four ways based on two factors: (1) no versus yes search by story topic, and (2) no versus yes search by writer profile. Dutch speaking women with breast cancer were recruited. Women who gave informed consent were randomly assigned to one of four groups. After searching for stories, women were offered a questionnaire relating to satisfaction with the search facility, the stories retrieved, and impact of the stories on coping with breast cancer. Of 353 enrolled women, 182 (51.6%) completed the questionnaire: control group (n = 37), story topics group (n = 49), writer profile group (n = 51), and combination group (n = 45). RESULTS: Questionnaire completers were evenly distributed over the four groups (chi(2) (3) = 3.7, P = .30). Women who had access to the story topics search facility (yes vs no): were more positive about (mean scores 4.0 vs 3.6, P = .001) and more satisfied with the search facility (mean scores 7.3 vs 6.3, P < .001); were more positive about the number of search options (mean scores 2.3 vs 2.1, P = .04); were better enabled to find desired information (mean scores 3.3 vs 2.8, P = .001); were more likely to recommend the search facility to others or intend to use it themselves (mean scores 4.1 vs 3.5, P < .001); were more positive about how retrieved stories were displayed (mean scores 3.6 vs 3.2, P = .001); retrieved stories that better covered their information needs (mean scores 3.0 vs 2.6, P = .02); were more satisfied with the stories retrieved (mean scores 7.1 vs 6.4, P = .002); and were more likely to report an impact of the stories on coping with breast cancer (mean scores 3.2 vs 2.9, P =. 02). Three main effects were associated with use of the writer profile search (yes vs no): being more positive about (mean scores 3.9 vs 3.6, P = .005) and more satisfied with the search facility (mean scores 7.1 vs 6.5, P =. 01), and being more positive about how retrieved stories were displayed (mean scores 3.8 vs 2.9, P < .001). For satisfaction with the search facility, an interaction effect was found (P = .03): at least one of the two search facilities was needed for satisfaction. CONCLUSIONS: Having access to the story topics search facility clearly had the most positive effect on patient satisfaction and search success.

Choosing a hospital for surgery: the importance of information on quality of care.

OBJECTIVE: To assess whether patients use information on quality of care when choosing a hospital for surgery compared with more general hospital information. METHODS: In this cross-sectional study in 3 Dutch hospitals, questionnaires were sent to 2122 patients who underwent 1 of 6 elective surgical procedures in 2005-2006 (aorta reconstruction [for treatment of aneurysm], cholecystectomy, colon resection, inguinal hernia repair, esophageal resection, thyroid surgery). Patients were asked which information they had used to choose this hospital and which information they intended to use if they would need similar surgical treatment in the future. RESULTS: In total, 1329 questionnaires were available for analysis (response rate 62.6%). Most patients indicated having used the hospital's good reputation (69.1%) and friendly hospital atmosphere (63.3%) to choose a hospital. For future choices, most patients intended to use the fact that they were already treated in that hospital (79.3%) and the hospital's good reputation (74.1%). Regarding quality-of-care information, patients preferred a summary measure (% patients with ''textbook outcome'') over separate more detailed measures (52.1% v. 38.0%, χ2 = 291, P < 0.01). For future choices, patients intend to use more information items than in 2005-2006, both in absolute terms (9 v. 4 items, t = 38.3, P < 0.01) as relative to the total number of available items (41.3% [40.1%-42.5%] v. 29.2% [28.1%-30.2%]). CONCLUSION: Patients intended to use more information for future choices than they used for past choices. For future choices, most patients prefer a summary measure on quality of care over more detailed measures but seem to value that they were already treated in that hospital or a hospital's good reputation even more.

Putting it all behind: long-term psychological impact of an inconclusive DNA test result for breast cancer.

PURPOSE: An inconclusive DNA-result for breast cancer may leave women with uncertainty that cannot be relieved. We assessed the influence of beliefs women held about their inconclusive DNA-result on psychological well-being and whether women had been able to put the period of DNA testing behind them. METHODS: In total, 215 women completed a baseline and a follow-up questionnaire 2.5 till 7 years after DNA test disclosure. Within the group of 147 women who received an inconclusive result (either a personal result or the result of an affected family member) multiple regression analyses were applied to investigate the relevance of women's personal beliefs. RESULTS: Personal beliefs and ambivalence about an inconclusive DNA-result were associated with cancer-related worry and distress (P < 0.05). Moreover, these beliefs seemed to be an especially strong predictor of whether women had been able to leave the period of DNA testing behind them, even after controlling for all measures of psychological distress (P < 0.001). DISCUSSION: Psychological distress measures may provide an important but incomplete picture of how women make sense of an inconclusive DNA-result. These findings underscore the importance of discussing counselees' beliefs and expectations openly to enhance well-being and adaptation on the long term.

The impact of individualized evidence-based decision support on aneurysm patients' decision making, ideals of autonomy, and quality of life.

BACKGROUND: Patients with an asymptomatic abdominal aneurysm and their surgeon were randomized to receive a general brochure (GB) or an IB presenting survival information and a ranking of the treatment strategies. Before and after receiving the brochure, patients filled out questionnaires on their behavior during the consultation, ideals of patient autonomy, and quality of life. Surgeons answered a short checklist evaluating the consultation. RESULTS: One hundred patients participated, 49 in the intervention, 51 in the control group. The IB group had a better understanding of important issues in the treatment decision, had prepared more questions, and was less satisfied with the duration of the consultation. Their impression that the surgeon perceived them more as a medical problem than a patient with a problem increased. They agreed less with the surgeon's advice and lost some of their belief in "the doctor knows best.'' Beforehand, the IB group had a stronger preference for patient-based decisions, but afterward they displayed more surgeon-based decisions. No effects were seen on patients' quality of life. CONCLUSIONS: Individualized evidence-based information stimulated patients' active involvement but in the context of our study led to less patient-based decisions. Patient-made decisions and patient autonomy should, however, not be equated.
