Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

4.4K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

714
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Integrated Healthcare System01:20

Integrated Healthcare System

2.5K
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Preventive Healthcare Services

2.3K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Pulse rhythm01:30

Pulse rhythm

1.5K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Area of Science:

  • Digital Health
  • Preventive Medicine
  • Behavioral Science

Background:

  • Mobile health (mHealth) has grown significantly, offering new ways to manage health, especially for chronic conditions.
  • Promoting healthy lifestyles via mHealth apps is a key area, but sustained user engagement remains a challenge.
  • The PRECIOUS project addresses this by developing a system to support self-management and behavior change.

Purpose of the Study:

  • To describe the pilot test protocol for the PReventive Care Infrastructure based on Ubiquitous Sensing (PRECIOUS) system.
  • To validate the PRECIOUS system, including the Bodyguard2 sensor and app, with end-users in a real-world setting.
  • To assess the system's potential for fostering behavior change, user acceptance, usability, and satisfaction.

Main Methods:

  • A pilot experimental study involving 31 morbidly obese prediabetic patients.
  • Randomization into three groups: control (usual care + sensor), PRECIOUS system (sensor + app), and PRECIOUS system + Motivational Interviewing.
  • Data collection over 3 months, focusing on healthy lifestyles, weight management, quality of life, and system usability.

Main Results:

  • Recruitment is complete with 31 participants.
  • Expected results indicate high patient acceptance and satisfaction with the PRECIOUS system, based on prior research.
  • Anticipated findings include acceptable usability of the preventive health solution.

Conclusions:

  • mHealth offers a powerful tool for continuous user support and feedback, crucial for adherence to healthy habits in chronic conditions.
  • The PRECIOUS system is an innovative solution designed to boost intrinsic motivation for lifestyle changes.
  • It integrates ubiquitous sensors and a scientifically grounded app to target physical activity, diet, and stress management.
