Summary
A new nursing workload intensity measurement system (WIMS) was developed. This system uses nursing diagnoses to predict required nursing time, offering a more accurate approach to staffing needs.
Area of Science:
- Healthcare Management
- Nursing Informatics
- Hospital Operations
Background:
- Current nurse staffing relies on outdated methods.
- A robust nurse-to-patient ratio measurement system is essential for effective healthcare delivery.
Purpose of the Study:
- To develop a prototype nursing workload intensity measurement system (WIMS).
- To establish a reliable methodology for assessing nursing staffing needs.
Main Methods:
- A questionnaire identified critical workload indicators.
- Regression modeling was employed to develop the WIMS.
- Data was collected from 19 wards in a 1500-bed acute care hospital over one week.
Main Results:
- The WIMS utilizes nursing diagnoses as key workload indicators.
- The developed model demonstrated good predictive ability (R² values 0.615–0.736).
- Nursing time requirements for low-acuity wards significantly increased.
Conclusions:
- The WIMS offers a potential methodology for measuring nursing staffing needs.
- Workload measurement systems require periodic review in dynamic healthcare settings.
- Patient dependency and acuity status should be analyzed separately for accurate workload prediction.

01:29Nursing Interventions II: Selecting and Classifying the Nursing Interventions
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
01:27Nursing Clinical Information System
Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

01:21Methods 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:
01:29Nursing Assessment
The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments and...

01:20Rheumatic Heart Disease IV: Nursing Management
AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...
01:15Nursing Evaluation
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.
