Guidelines for management of HIV infection with computer-based patient's record
Lancet (London, England)
|August 5, 1995
Summary
Electronic medical records significantly improved clinician adherence to HIV clinical practice guidelines by reducing alert and reminder response times. This technology enhanced guideline compliance without negatively impacting primary care visits or hospitalizations.
Area of Science:
- Clinical Informatics
- Health Services Research
- Infectious Disease Management
Background:
- Computers are increasingly integrated into clinical settings.
- Adherence to clinical practice guidelines is crucial for effective patient care.
- Electronic medical records (EMRs) offer potential for improving guideline adherence.
Purpose of the Study:
- To evaluate the effectiveness of electronic messages within EMRs in enhancing adherence to clinical practice guidelines.
- To assess the impact of EMR-based alerts and reminders on clinician response times and patient outcomes in HIV care.
Main Methods:
- A nonrandomized, controlled, prospective trial involving 126 physicians and nurse practitioners.
- Study focused on 349 patients with HIV infection in a primary care setting.
- Analysis of clinician response times to alerts and reminders, ambulatory visits, and hospitalizations.
Main Results:
- Median response time to alerts decreased significantly from 52 days (control) to 11 days (intervention) (p < 0.0001).
- Median response time to reminders decreased significantly from over 500 days (control) to 114 days (intervention) (p < 0.0001).
- No significant difference in primary care visits, hospital admission rates, or survival; however, increased ophthalmologist visits were noted.
Conclusions:
- EMR systems with electronic messaging are effective tools for improving clinician adherence to practice guidelines.
- The intervention demonstrated a substantial improvement in timely responses to clinical prompts.
- Further investigation into specific specialist visit patterns may be warranted.

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.

01:26Guidelines for Nursing Documentation II
Effective documentation is an integral part of nursing practice. Here are some essential guidelines to follow when documenting patient care:
Timely documentation is crucial to ensure continuity of care for patients. Any delays in recording or reporting medical information can result in medical errors and even adverse patient outcomes. From medication administration to diagnostic test results, every detail must be accurately and promptly documented to provide the best possible care for patients.

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
