All of the techniques exhibited trueness and had acceptable precision. The variation of the angle of the implants did not affect the accuracy of the techniques.
The quality of data in electronic healthcare databases is a critical component when used for research and health practice. The aim of the present study was to assess the data quality in the Paulista Cardiovascular Surgery Registry II (REPLICCAR II) using two different audit methods, direct and indirect. The REPLICCAR II database contains data from 9 hospitals in São Paulo State with over 700 variables for 2229 surgical patients. The data collection was performed in REDCap platform using trained data managers to abstract information. We directly audited a random sample (n = 107) of the data collected after 6 months and indirectly audited the entire sample after 1 year of data collection. The indirect audit was performed using the data management tools in REDCap platform. We computed a modified Aggregate Data Quality Score (ADQ) previously reported by Salati et al. (2015). The agreement between data elements was good for categorical data (Cohen κ = 0.7, 95%CI = 0.59-0.83). For continuous data, the intraclass coefficient (ICC) for only 2 out of 15 continuous variables had an ICC < 0.9. In the indirect audit, 77% of the selected variables (n = 23) had a good ADQ score for completeness and accuracy. Data entry in the REPLICCAR II database proved to be satisfactory and showed competence and reliable data for research in cardiovascular surgery in Brazil.
BackgroundStudies have shown the impact of atrial fibrillation (AF) on the patients'
quality of life. Specific questionnaires enable the evaluation of relevant
events. We previously developed a questionnaire to assess the quality of
life of patients with AF (AFQLQ version 1), which was reviewed in this
study, and new domains were added.ObjectiveTo demonstrate the reproducibility of the AFQLQ version 2 (AFQLQ v.2), which
included the domains of fatigue, illness perception and well-being.MethodsWe applied 160 questionnaires (AFQLQ v.2 and SF-36) to 40 patients, at
baseline and 15 days after, to measure inter- and intraobserver
reproducibility. The analysis of quality of life stability was determined by
test-retest, applying the Bartko intraclass correlation coefficient (ICC).
Internal consistency was assessed by Cronbach's alpha test.ResultsThe total score of the test-retest (n = 40) had an ICC of 0.98 in the AFQLQ
v.2, and of 0.94 in the SF36. In assessing the intra- and interobserver
reproducibility of the AFQLQ v.2, the ICC reliability was 0.98 and 0.97,
respectively. The internal consistency had a Cronbach's alpha coefficient of
0.82, compatible with good agreement of the AFQLQ v.2.ConclusionThe AFQLQ v.2 performed better than its previous version. Similarly, the
domains added contributed to make it more comprehensive and robust to assess
the quality of life of patients with AF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
