Insights
The Brief International Classification of Functioning, Disability, and Health (ICF) Core Set for chronic ischemic heart disease (CIHD) is validated for Turkish patients. It effectively assesses the broad impact of CIHD, supporting patient-centered care.
Area of Science:
- Cardiology
- Rehabilitation Medicine
- Health Sciences
Background:
- Chronic ischemic heart disease (CIHD) significantly impacts patients' daily lives and functioning.
- A comprehensive assessment tool is needed to understand the multifaceted nature of CIHD's impact.
- The International Classification of Functioning, Disability, and Health (ICF) provides a standardized framework for such assessments.
Purpose of the Study:
- To validate the Brief ICF Core Set for CIHD in a Turkish patient population.
- To identify the most common functional impairments and challenges faced by CIHD patients.
- To test the construct validity of the Brief ICF Core Set for CIHD through correlation with clinical assessment scales.
Main Methods:
- A cross-sectional study involving 85 patients diagnosed with CIHD was conducted.
- The Brief ICF Core Set for CIHD, comprising 36 second-level categories, was administered.
- Correlations between ICF categories and established clinical assessment scales were analyzed.
Main Results:
- Key impairments in body functions included heart, blood pressure, and exercise tolerance.
- The cardiovascular system structure was affected in 97.6% of patients.
- Activities like moving, employment, and daily routines were frequently problematic, with environmental factors acting as both barriers and facilitators.
Conclusions:
- The Brief ICF Core Set for CIHD is a valid instrument for evaluating the diverse effects of CIHD in Turkish patients.
- This validation supports its application in clinical settings for comprehensive, patient-centered CIHD management.
- A holistic approach is crucial for effectively managing patients with chronic ischemic heart disease.
Objectives:
This study aimed to validate the Brief International Classification of Functioning, Disability, and Health (ICF) Core Set for chronic ischemic heart disease (CIHD) in a Turkish patient population, identifying the most common problems in ICF categories and testing its construct validity.
Patients And Methods:
A total of 85 patients (28 males, 57 females; mean age: 64.4±12.2 years; range, 37 to 88 years) diagnosed with CIHD who were referred to our cardiac rehabilitation outpatient clinic were included in the cross-sectional study between February 2014 and August 2015. Brief ICF Core Set for CIHD, which includes 36 second-level categories, was used to assess the most common impairments. Correlations between these impairments and various clinical assessment scales were analyzed to test construct validity.
Results:
The most impaired categories in body functions were heart functions, blood pressure functions, exercise tolerance functions, blood vessel functions, sensations associated with cardiovascular and respiratory functions, and energy and drive functions. In the body structure component, the structure of the cardiovascular system was identified as a problem in 97.6% of patients. The activities and participation component revealed that moving around, remunerative employment, and carrying out daily routines were frequently problematic. All of the environmental factors were identified as both barriers and facilitators. Significant correlations were found between these categories and various clinical assessment scales.
Conclusion:
The Brief ICF Core Set for CIHD is a valid tool for assessing the multifaceted impact of CIHD in a Turkish patient population. This validation supports its use for comprehensive, patient-centered evaluations in clinical settings, emphasizing the need for a holistic approach to managing CIHD.
