Influence of Disease-Related Stigma on Patients’ Decisions to Upload Medical Reports to the German Electronic Health Record: Randomized Controlled Trial

Influence of Disease-Related Stigma on Patients’ Decisions to Upload Medical Reports to the German Electronic Health Record: Randomized Controlled Trial

To investigate the first use case, we used a mixed methods design where the experimental intervention was based on an interview study with potential EHR users [31]. The interview study showed that the time course of a disease (chronic vs acute) and disease-related stigma influence people’s decisions to upload a medical report to the EHR. The following experiment showed that respondents were more likely to upload a medical report of a chronic disease to the EHR than to upload a report of an acute condition.

Extending the Privacy Calculus to the mHealth Domain: Survey Study on the Intention to Use mHealth Apps in Germany

Extending the Privacy Calculus to the mHealth Domain: Survey Study on the Intention to Use mHealth Apps in Germany

We then validate our model in a survey study using a covariance-based structural equation model (CB-SEM). After discussing the results, we derive theoretical and practical implications and reflect on the limitations of the study. We end our paper with a conclusion concerning our objectives. To predict and examine the intention to use m Health apps, we adapted a privacy calculus model from the SNS domain [12].

Characteristics of Users and Nonusers of Symptom Checkers in Germany: Cross-Sectional Survey Study

Characteristics of Users and Nonusers of Symptom Checkers in Germany: Cross-Sectional Survey Study

In the third section, we asked participants how often they use the internet (several times a day, once a day, several times a week, several times a month, or less than once a month) and we assessed their affinity for technology interaction (using the Affinity for Technology Interaction [ATI] scale [46]). We also assessed their health app usage by asking whether they generally use health apps (yes/no).

Paradigmatic Approach to Support Personalized Counseling With Digital Health (iKNOW)

Paradigmatic Approach to Support Personalized Counseling With Digital Health (iKNOW)

Therefore, a major challenge for counseling physicians is to translate complicated probabilities for different time periods into easy-to-understand risk formats as a prerequisite for shared decision-making. A second important ingredient of any counseling session is up-to-date, evidence-based information on screening and preventive measures based on current guidelines. In this context, scientific progress and a rapidly changing evidence base are major challenges.

Triage Accuracy of Symptom Checker Apps: 5-Year Follow-up Evaluation

Triage Accuracy of Symptom Checker Apps: 5-Year Follow-up Evaluation

As the interpretation of a vignette may change if it does not include a particular piece of information that is requested by a symptom checker (eg, the chief complaint’s duration), we used several measures to augment the case description and, thus, improve the comparability of vignettes across the different symptom checkers.

Determinants of Laypersons’ Trust in Medical Decision Aids: Randomized Controlled Trial

Determinants of Laypersons’ Trust in Medical Decision Aids: Randomized Controlled Trial

We used a 1-factorial experimental design with factor framing and factor levels of anthropomorphic framing and framing as AI along with a control group (allocation ratio 1:1:1). These were manipulated by integrating a picture of a physician, an iconographic representation of AI similar to that displayed by Symptomate [28], or a mock company logo into the mock symptom checker’s advice screen (Figure 1).

A Remote Patient-Monitoring System for Intensive Care Medicine: Mixed Methods Human-Centered Design and Usability Evaluation

A Remote Patient-Monitoring System for Intensive Care Medicine: Mixed Methods Human-Centered Design and Usability Evaluation

For step 5, we chose a single-factor 2-group study design, as described by Gravetter and Forzano [35]. The research approach, beginning with usability testing and identification of major problems in design A, followed by prototyping of design B and its usability testing, concluding with a comparison between design A and design B.

Patient Monitoring Alarms in an Intensive Care Unit: Observational Study With Do-It-Yourself Instructions

Patient Monitoring Alarms in an Intensive Care Unit: Observational Study With Do-It-Yourself Instructions

In intensive care units (ICUs), monitoring of patients’ physiologic parameters has significantly improved patient safety by alerting ICU staff through a visual or audible alarm [1] when a parameter deviates from the preset range (eg, apnea, sensor detachment). However, as one of the most digitized health care areas with a rising number of novel devices with their own alarms, the sheer number of alarms regularly overwhelms ICU staff.
