Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
Formulating and Validating Nursing Diagnosis II01:25

Formulating and Validating Nursing Diagnosis II

Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.
Risk nursing diagnoses represent clinical judgments of an individual, family, or community more vulnerable to developing the health problem than others...
Documentation of Nursing Diagnosis01:10

Documentation of Nursing Diagnosis

The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters assessment...
Formulating and Validating Nursing Diagnosis I01:26

Formulating and Validating Nursing Diagnosis I

A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.
There are thirteen domains for...
Nursing Diagnosis01:22

Nursing Diagnosis

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Area of Science:

  • Diagnostic accuracy research
  • Evidence-based medicine
  • Health services research

Background:

  • Accurate diagnosis is crucial for appropriate patient treatment and prognosis.
  • Methodological flaws are common in test accuracy studies.
  • The HSRC evidence-based diagnosis programme addresses systematic reviews of diagnostic tests.

Purpose of the Study:

  • To improve methods for systematic reviews of test accuracy studies.
  • To address the wider context of test ordering and interpretation.
  • To enhance the reliability of diagnostic processes.

Main Methods:

  • Conducted projects on literature searching, quality assessment, and meta-analysis.
  • Evaluated diagnostic filters and summary quality scores.
  • Developed statistical models (HSROC and bivariate) for meta-analysis.
  • Created a Stata module for accessible statistical modeling.

Main Results:

  • Systematic reviews require broad database searches; diagnostic filters lack accuracy.
  • The Quality Assessment of Studies of Diagnostic Accuracy included in Systematic Reviews (QUADAS) tool is acceptable.
  • Hierarchical summary receiver operating characteristic (HSROC) and bivariate models are statistically equivalent in many cases.

Conclusions:

  • Refined methods enhance systematic reviews of diagnostic test accuracy.
  • Further research is needed in literature searching, individual patient data synthesis, and results presentation.
  • Improved methods contribute to more reliable diagnostic decision-making.
