Nursing Diagnosis

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...

Epilepsy and Seizures: Overview

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Setting Time of Cement

Setting Time of Cement

The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

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...

Formulating and Validating Nursing Diagnosis I

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...

Background:

Automated epilepsy diagnosis using electroencephalogram (EEG) has seen numerous predictive models developed over the past decade.
A significant limitation in existing studies is the lack of evaluation on independent test sets, leading to inflated performance metrics.
Benchmark EEG datasets may possess inherent limitations that hinder the generalizability of epilepsy diagnostic classifiers.

Purpose of the Study:

To address the limitations of existing EEG-based epilepsy diagnosis models by evaluating them on a holdout test set.
To propose and validate a novel engineered feature for epilepsy diagnosis that accurately characterizes neuronal synchronization from scalp EEG.
To establish a new benchmark for automated epilepsy diagnosis through rigorous test set evaluation.

Main Methods:

Two previously reported EEG classifiers were implemented and evaluated on a benchmark dataset and a subsequent test set.
A novel feature was engineered to characterize neuronal synchronization by extending linear time-invariant system concepts to matrices.
The proposed feature was tested on scalp EEG data from 50 epileptic and 50 healthy subjects.

Main Results:

Previously reported classifiers showed a sharp decline in accuracy when evaluated on a test set.
The novel engineered feature achieved an Area Under the Curve (AUC) of 0.87 on test data.
The proposed feature outperformed existing models, which yielded an AUC of 0.80, setting a new benchmark for epilepsy diagnosis.

Conclusions:

Existing EEG-based epilepsy diagnosis models may not generalize well due to a lack of test set evaluation.
The newly engineered feature demonstrates superior performance and establishes a more reliable benchmark for automated epilepsy diagnosis.
The proposed feature exhibits statistical consistency across different conditions and robustness against EEG artifacts, enhancing its clinical applicability.
