Documentation of Nursing Diagnosis

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...

Methods of Documentation III: PIE

Methods of Documentation III: PIE

Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:

Data Validation

Data Validation

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Area of Science:

Dental Informatics
Human-Computer Interaction
Health Information Technology

Background:

Poor usability of electronic health records (EHRs) is a significant barrier to their optimal use in dentistry.
Dentists increasingly use structured data entry in EHRs for data retrieval and exchange.
A lack of standardized terminology for oral health diagnoses has historically limited EHR data consistency.

Purpose of the Study:

To evaluate the usability of a common EHR interface for entering diagnostic terms.
To identify and address usability problems through an iterative design process with the vendor.

Main Methods:

User testing with dental providers (n=32).
Interviews (n=36) and observations (n=24) at two clinical sites.
Mixed-methods approach to identify and characterize usability issues.

Main Results:

User testing showed low success rates for entering diagnoses (22-41% for simple tasks, 0% for complex tasks).
Identified 24 high-level usability problems affecting efficiency and causing errors.
Problems included interface design flaws, terminology issues (missing/mis-categorized concepts), and work domain inefficiencies.

Conclusions:

Mixed methods revealed critical usability issues in the EHR interface, terminology, and work domain.
These usability challenges significantly impede users from completing tasks.
Future work will assess the impact of interface, terminology, and work domain changes on usability.
