Errors occurring during blood pressure monitoring

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
Several factors...

Health Information Technology and Healthcare Information System

Health Information Technology (HIT)
Health Information Technology, commonly called HIT, integrates advanced information systems and technology in healthcare settings. Its primary functions include:

Healthcare Associated Infections II: Preventive Measures

Healthcare Associated Infections II: Preventive Measures

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...

Patient-centered Care

Patient-centered Care

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Methods of Documentation VI: Case Management Model

Methods of Documentation VI: Case Management Model

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Area of Science:

Clinical Chemistry
Laboratory Medicine
Healthcare Quality Improvement

Background:

Point-of-care testing (POCT) is expanding globally, yet concerns persist regarding the quality of test results.
Existing guidelines and standards for POCT practices are not universally ensuring optimal testing quality.

Purpose of the Study:

To investigate the current practices and identify areas for improvement in worldwide point-of-care testing.
To gather insights from POCT analysts regarding their experiences and perceived needs.

Main Methods:

An online questionnaire was distributed globally to POCT analysts via a commercial survey website.
Participants were recruited from healthcare providers subscribed to a specific industry newsletter or website visitors.

Main Results:

The majority of POCT occurs in hospitals, with regulatory mandates generally followed.
Most analysts receive training from manufacturers, and a high percentage verify devices before use.
While most stop testing when quality control limits are exceeded, some use expired materials, and few find their organization's POCT acceptable.

Conclusions:

POCT practices are evolving positively, contributing to patient safety.
Analysts recognize existing issues and highlight the need for improved training, clearer manufacturer instructions, and better quality control mechanisms.
