Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Current Trends in Nursing II

Current Trends in Nursing II

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Holter Monitor: 24-Hour Monitoring

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Area of Science:

Biomedical Engineering
Sensor Technology
Digital Health

Background:

Smartphone-based biosensors represent a significant advancement in modern healthcare, offering sensitive and effective diagnostic capabilities.
Despite technological progress, a notable decline in patent filings for smart biosensors in healthcare has been observed in recent years.

Purpose of the Study:

To review the current state-of-the-art of various smartphone-based biosensor technologies across different development stages.
To critically analyze the reasons behind the limited market entry of many smart biosensor technologies.

Main Methods:

Comprehensive literature review of recent smartphone-based biosensor developments.
Analysis of patent and patent application trends in smart biosensors for healthcare.
Critical evaluation of technical and end-user adoption challenges hindering commercialization.

Main Results:

While numerous effective smartphone biosensor technologies exist, commercial availability remains limited.
A decrease in patent applications suggests potential stagnation or challenges in the translation of research to market.

Conclusions:

Significant evolution in smart biosensor technology has not translated into widespread market presence.
There is a critical need to enhance technology transfer, application, and end-user adoption to realize the full potential of smartphone biosensors in healthcare.
