Health Literacy01:21

Health Literacy

4.6K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

Bioavailability Study Design: Healthy Subjects Versus Patients

25
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Methods of Documentation VII: EMR

1.1K
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

Assessment of the Gastrointestinal System II: Health Perception Pattern

206
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

13.7K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Area of Science:

  • Digital Health
  • Health Communication
  • Patient Engagement

Background:

  • eHealth literacy impacts patient behavior, relationships, adherence, and outcomes.
  • Online health communities (OHCs) improve resource utilization and adherence but lack eHealth literacy studies.
  • This study focuses on eHealth literacy, health information seeking, and physician-patient communication within OHCs.

Purpose of the Study:

  • To investigate the association between eHealth literacy in OHCs and patient adherence.
  • To explore the mediating roles of physician-patient communication and health information-seeking behavior.
  • To apply social cognitive theory to understand these relationships.

Main Methods:

  • An empirical study using a research model with eHealth literacy as the independent variable and patient adherence as the dependent variable.
  • Mediating variables included physician-patient communication, health information-seeking behavior, and perceived information quality in OHCs.
  • Data collected via an online survey of 560 participants in Chinese OHCs, analyzed using partial least squares and structural equation modeling.

Main Results:

  • A response rate of 79.6% (446 participants) was achieved with acceptable validity and reliability.
  • Demographic factors (age, gender, living area, education) were associated with adherence and communication.
  • Patients' eHealth literacy positively correlated with adherence, mediated by communication, information seeking, and perceived information quality in OHCs.

Conclusions:

  • Physician-patient communication, information seeking, and perceived information quality in OHCs significantly improve adherence, guided by eHealth literacy.
  • Physicians should guide patients' eHealth literacy to enhance treatment efficiency.
  • OHC operators must improve information quality management and user experience to bridge the perceived information gap.
