Restorative Care

Restorative Care

Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Specialized Care Centers and Settings-I

Specialized Care Centers and Settings-I

Specialized care settings or centers are situated in convenient locations within the community and offer care to a specific group or population. They consist of daycare facilities, mental health facilities, rural health facilities, educational institutions, industries, shelters for the homeless, and rehabilitation facilities.
Daycare centers
They provide several functions. Some facilities care for healthy newborns and children whose parents work, while others are medically focused and care for...

Nursing Assessment

Nursing 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...

Planning Nursing Care I

Planning Nursing Care I

The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

Psychosis: Goals of Pharmacotherapy

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...

Drug Therapy

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Area of Science:

Health Services Research
Clinical Informatics
Patient Outcomes

Background:

Determining optimal hospital length of stay (LOS) is complex, influenced by numerous clinical and non-clinical variables.
Standardized tools are needed to objectively assess these variables for consistent patient management.
Existing methods for LOS prediction may lack comprehensive assessment of influencing factors.

Purpose of the Study:

To develop and validate a set of rating scales designed to quantify variables influencing the optimal length of hospital stay.
To evaluate the psychometric properties of these newly developed scales, including interrater reliability and factor structure.
To examine the relationship between identified factors and the actual length of stay in a clinical setting.

Main Methods:

Development of a comprehensive set of rating scales based on clinician-identified variables.
Conducting interrater reliability studies to assess the consistency of scale application.
Performing factor analysis to identify underlying dimensions measured by the scales.
Correlational analysis to link scale factors with actual patient length of stay.

Main Results:

The developed rating scales demonstrated acceptable to good interrater reliability.
Factor analysis revealed distinct underlying dimensions influencing length of stay.
Significant correlations were found between specific scale factors and actual length of stay.
The scales provide a quantifiable measure of factors impacting hospital LOS.

Conclusions:

The validated rating scales offer a promising tool for assessing factors that determine optimal hospital length of stay.
These scales can enhance clinical decision-making regarding patient discharge planning.
The scales have potential applications in both clinical practice and health services research for LOS optimization.
