Instruments Each of the segments of the Doctor of Nursing Practice (DNP) project requires significant knowledge in nursing and research methodology. The project’s success depends on the conscious setting of goals, effective decision-making, a detailed analysis of the premises and data, as well as an understandable and proper formulation of the hypothesis, thesis statement, and results. Research instruments, data collection, and data analysis plan are also crucial elements for developing valid and reliable knowledge. Patient satisfaction is a major qualitative indicator of the effectiveness of an intervention. This variable is crucial in chronic care management (CCM) because patients who use chronic care services constantly have to put up with adverse effects of their conditions. Their level of satisfaction shows how effective measures applied by health care providers are. Patient-Reported Outcome Measures (PROMs) are among the most effective assessment tools in healthcare that have recently begun to gain popularity in various areas of care, and CCM is no exception. According to Bingham III et al. (2019), “increasingly, PROs are used to screen across general areas of health to identify problems and needs.” (p. 138). Experts note that PROMs are “are standardized, validated surveys … used to study how you feel about your health status” ( Patient-reported outcome measures , n.d., para. 3). Although it should be mentioned that PROMs are more of a principle according to which questionnaires and surveys are compiled than a research instrument. Therefore, after a lengthy review of the different variations of PROMs, the Kansas City Cardiomyopathy Questionnaire (KCCQ) was chosen as the primary research instrument. According to the scientific community, “the Kansas City Cardiomyopathy Questionnaire is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life” ( The Kansas City cardiomyopathy questionnaire , 2015, para. 2). Professionals note that it is “the most sensitive, specific, and responsive health-related quality of life measure for heart failure” ( The Kansas City cardiomyopathy questionnaire , 2015, para. 1). Moreover, Napier et al. (2018) argue that it has significant internal consistency, its Cronbach’s alpha in terms of a clinical summary is 0.91, and in terms of quality of life, it is 0.87. The available evidence shows that KCCQ, being one of the best tools for the qualitative assessment of patients with heart diseases, is effective and has excellent practical potential (Bingham III et al., 2019). However, the researchers warn that there are some difficulties motivating patients to take PROMs questionnaires regularly and implementing the findings into new and innovative healthcare practices. Data Collection Procedures As mentioned above, the correct choice of data collection methods is crucial for the entire DNP project. The wrong approach can fatally affect the study results and conclusions, and the time spent on the intervention will be wasted. One of the main rules for choosing data collection methods is that the procedures should be appropriate for the nature of the rese
