Evaluation of nursing practice: process and critique

Area of Science:

• Nursing Science
• Health Services Research
• Philosophy of Science

Background:

• Evaluating nursing practice models in clinical trials is complex.
• Existing research faces methodological hurdles.
• Improvements are needed to strengthen the evaluation process.

Purpose of the Study:

• To describe challenges in clinical trials for nursing practice models.
• To offer suggestions for enhancing trial methodologies.
• To present a case study of a specific nursing practice model trial.

Main Methods:

• Description of a clinical trial for a nursing practice model.
• Synthesis of Aristotelian theory with Rogers' science.
• Examination of research procedures, methodological limitations, and model specifications.

Main Results:

• The study details the rationale behind chosen research procedures.
• Methodological limitations inherent in the study design are analyzed.
• Specifications of the nursing practice model are presented.

Conclusions:

• Clear specification of theoretical relationships within practice models is crucial.
• Identifying key intervening variables enhances the connection between treatment and outcome.
• Improved clarity in model specification and variable identification strengthens nursing research validity.
