Title:A Methodological Study To Develop And Evaluate Usability Of A Nursing Checklist For Patients Undergoing Cardiac Catheterization
Author Name:Jogindra Vati, Rupinder Kaur and Yash Paul Sharma
Synopsis:
Cardiac Catheterization is one of the procedures for the diagnosis of coronary artery diseases. Nurses play an important role in taking care of patients undergoing cardiac catheterization and safety is the prime concern of nurses. A methodological study was conducted in Cardiac Catheterization Lab and Cardiology Units of Advance Cardiac Centre in a tertiary care hospital of north India during the year 2011-12 to develop a valid and reliable Nursing Checklist in order to ensure safety for patients undergoing Cardiac Catheterization and evaluate its usability. Cardiac Catheterization Nursing Checklist (CCNC) was developed in five phases. In the first preliminary phase, a rough draft of 90-items was prepared. During second phase, content validation was done by 9 experts using three rounds of Delphi technique. In the third phase, a pilot study was conducted on 5 subjects to check its feasibility. Checklist was modified based on findings of pilot study, and again content was validated by 9 experts using fourth round of Delphi technique. During fourth phase, checklist was administered on 40 subjects by two observers to check Inter-rater reliability. In the final phase, checklist was administered on 60 patients undergoing cardiac catheterization to check its internal consistency and construct validation. To evaluate usability of checklist, opinion of all staff including doctors and nurses working in the Cardiac units (N=15) was sought by using 5-items opinionnaire. The statistics such as Cohen's Kappa coefficient, Cronbach's alpha, exploratory factor analysis, item total correlation was applied to check its reliability and validity. Usability of checklist was measured by calculating mean score and agreement percentage. The item total correlation coefficient ranged from 0.45 to 0.95. Six factors under three dimensions (CCNC-92 items) were singled out after factor analysis. Correlations between different factors were partially confirmed showing convergent validity. Overall reliability/internal consistency (Cronbach's α) of the CCNC was found 0.88, varied from 0.60-0.88. Mean score of staff regarding usability of checklist was 3.6 with average agreement of 73%. Results of the study demonstrated that CCNC is a multidimensional, valid and reliable tool. It can be used in day to day clinical practice to ensure safety for patients undergoing Cardiac Catheterization in a tertiary care hospital. Further studies need to be conducted on a large sample in different settings for generalization.
