Data Reporting and Recording01:24

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Types of Reports II: Incident or Occurrence Report

1.3K
An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.
Purposes:
In the healthcare industry, reports play a crucial role in documenting incidents within an agency. The primary objective of these reports is to ensure patient safety, uphold the...

Reporter Genes02:11

Reporter Genes

13.4K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Introduction to Documentation and Reporting01:20

Introduction to Documentation and Reporting

3.1K
Documentation is the systematic process of formally recording, maintaining, and communicating information.
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Pharmacology

Background:

  • Hydroxychloroquine (HCQ) is widely used for autoimmune conditions like rheumatoid arthritis.
  • HCQ retinopathy can lead to irreversible central vision loss, even after drug cessation.
  • Early detection and appropriate dosing are crucial to mitigate visual sequelae.

Observation:

  • A 61-year-old woman developed HCQ retinopathy despite a daily dose below the 2011 American Academy of Ophthalmology (AAO) guideline threshold but above the 2016 revised threshold.
  • She presented with progressive central vision loss and a scotoma after 6 years of HCQ treatment.
  • Ophthalmic examination revealed bilateral bull's-eye maculopathy, characteristic structural changes on OCT, and visual field defects.

Findings:

  • The patient's HCQ dose (5.72 mg/kg real body weight) exceeded the 2016 AAO recommendation (5.0 mg/kg real body weight), indicating toxicity despite adherence to older guidelines.
  • Diagnostic findings included bull's-eye maculopathy, parafoveal ellipsoid zone loss on OCT, and paracentral visual field loss.
  • The patient was switched to sulfasalazine.

Implications:

  • This case highlights the importance of adhering to the updated 2016 AAO guidelines for HCQ dosing and monitoring.
  • Revised guidelines aim to improve early detection of HCQ retinopathy and prevent irreversible vision loss.
  • Physicians should be aware of the evolving recommendations for HCQ safety to protect patient vision.
