Several surveys have presented the quality of reports on randomized clinical trials (RCTs) published in general and specialty medical journals. The aim of these surveys was to raise scientific consciousness on methodological aspects pertaining to internal and external validity. These reviews have suggested that the methodological quality could be improved. Objective. We conducted a survey of reports on RCTs published in nursing journals to assess their methodological quality. The features we considered inclUded sample size, flow of participants, assessment of baseline comparability, randomization, blinding, and statistical analysis. Methods. We collected data from all reports of RCTs published between January 1994 and December 1997 in Applied Nursing Research, Heart &. Lung and Nursing Research. We hand-searched the journals and included all 54 articles in which authors reported that individuals have been randomly allocated to distinct groups. We collected data using a condensed form of the Consolidated Standards of Reporting Trials (CONSORT) statement for structured reporting of RGs [Begg et al.. 1996). Background A randomized clinical trial (RCT) provides the most valid basis for assessing the benefits of health care interventions. Results of a published RCT will be most influential on patient care if the reader can appreciate both the methodological quality of the trial and the quality of the report. The methodological quality of a trial itself depends on the accurate accomplishment of several fundamental steps. The quality of the report depends on whether the published RCT provides readers with adequate information on the design, Results. Sample size calculations were included in only 22% of the reports. Only 48% of the reports provided information about the type of randomization, and a mere 22% described blinding strategies. Comparisons of baseline characteristics using hypothesis tests were abusively produced in more than 76% of the reports. Excessive use and unstructured reports of significance testing were common [59%\. and all reports failed to provide magnitude of treatment differences with confidence intervals. Conclusions. Better methodological quality in reports of RCTs will contribute to increase the standards of nursing research. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
