Data Reporting and Recording01:24

Data Reporting and Recording

5.4K
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...

Design Example: Setting a Curve Using Design Data

233
Designing and plotting a curve using field data requires precise calculations and execution. A horizontal curve with a radius of 200 meters and an intersection angle of 20 degrees is established using the method of perpendicular offsets from the long chord. The long chord, which spans between the curve's endpoints, is calculated to be 69.46 meters in length. To maintain accuracy in plotting, intervals of 3 meters are selected along the chord.The engineer determines the offset distances for each...

Assessment of the Gastrointestinal System I: Subjective Data01:17

Assessment of the Gastrointestinal System I: Subjective Data

652
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Assessment of the Cardiovascular System I: Subjective Data

827
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...

Deleterious Substances in Aggregate01:25

Deleterious Substances in Aggregate

542
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

423
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Area of Science:

  • Public Health
  • Forensic Science
  • Addiction Research

Background:

  • Accurate substance use assessment is crucial for public health, clinical care, and research.
  • Self-reports are common but susceptible to social desirability and recall biases.
  • Objective measures like hair toxicology offer extended detection windows and enhanced data validity.

Purpose of the Study:

  • To assess concordance between self-reported substance use and hair toxicology results.
  • To investigate the prevalence and predictors of underreporting substance use.
  • To examine the relationship between cannabis use patterns and THC detection in hair.

Main Methods:

  • Collected self-reported substance use data via questionnaire from 75 adult participants.
  • Analyzed hair samples using liquid chromatography-mass spectrometry (LC-MS/MS) for drug detection over 3 months.
  • Defined underreporting as a negative self-report with a positive hair test result.

Main Results:

  • 21.3% of participants underreported the use of at least one substance.
  • Self-reported cannabis frequency and quantity predicted THC detection in hair.
  • No sociodemographic factors or alcohol use patterns predicted underreporting.

Conclusions:

  • Sole reliance on self-reports for substance use assessment is limited due to underreporting.
  • Integrating objective hair toxicology improves accuracy and addresses disclosure biases.
  • A combined approach is vital for reliable substance use data in sensitive settings.
