Dataset Information

Preparation, validation, and evaluation of an information leaflet for patients undergoing day-care surgeries under general anesthesia at a busy tertiary care hospital.

ABSTRACT:

Background and aims

It is essential that patients posted for day-care surgeries are adequately prepared preoperatively. Verbal information alone may not be always effective. This study aimed to prepare, validate, and evaluate the efficacy of a patient information leaflet (PIL) for patients undergoing day-care surgeries under general anesthesia (GA).

Material and methods

After approval from the hospital ethics committee a PIL was prepared in English. Readability and design of the leaflet were checked using standard tests: Flesch readability ease test (FRE), Flesch Kincaid grade level (FKGL), and Baker Able leaflet design (BALD). It was translated into three regional languages. The PIL was tested among patients using a questionnaire. Seventy-nine adult patients posted for elective day-care procedures were included while emergency surgeries were excluded. Patient knowledge pre and post-PIL was compared using paired 't' test. The influence of age, gender, and education level on the usefulness of PIL were analyzed using the Chi-square test and knowledge was compared using ANOVA.

Results

The English leaflet had an FRE Score of 63.9 and FKGL of 6.4, which is "standard". The BALD score for all leaflets was 25 ("above standard"). The overall knowledge scores significantly improved from 52.6% (preintervention) to 70.7% (postintervention), P < 0.001. Knowledge improvement was seen with the use of PIL in all four languages. Sixty eight percent of patients strongly recommended the PIL while 31% were willing to recommend it to others.

Conclusion

The PILs developed in this study have standard readability, good design and validated for efficacy.

Project description:BackgroundAbnormal cardiac repolarization, indicated by a prolongation of the QT interval, increases the risk for torsades de pointes, a potentially life-threatening arrhythmia. Many perioperatively administered drugs and conditions prolong the QT interval. Despite several reports of perioperative torsades de pointes, systematic evidence regarding perioperative QT interval prolongation is limited.MethodsSerial postoperative 12-lead electrocardiograms were obtained from 469 adult patients undergoing major noncardiac surgery under general anesthesia. Heart rate corrected QT-interval duration (Fridericia formula) was the primary outcome. All perioperatively administered drugs were recorded. Emphasis was placed on absolute QTc prolongation greater than 500 ms and relative increases of 30 and 60 ms.ResultsAt the end of surgery, 80% of the patients (345 of 429) experienced a significant QTc interval prolongation (ΔQTc 23 ± 26 ms (mean and SD), 95% CI 20-25 ms, P less than 0.001). Approximately 51% (219 of 429) had a QTc greater than 440 ms, and 4% (16 of 429) a QTc greater than 500 ms. In 39% (166 of 429), the ΔQTc was greater than 30 ms, in 8% (34 of 429) >60 ms, and in greater than 0.5% (2 of 429) >100 ms. No changes in ΔQTc occurred at subsequent time points. One patient developed torsades de pointes with a ΔQTc: 29 ms (0.4% incidence rate). Several drugs had a large effect on ΔQTc: isoflurane, methadone, ketorolac, cefoxitin, zosyn, unasyn, epinephrine, ephedrine, and calcium. Postoperative body temperature had a weak negative correlation with ΔQTc (r = -0.15, P = 0.02); serum magnesium, potassium, and calcium concentrations were not correlated.ConclusionPostoperative QT-interval prolongation is common. Several perioperatively administered drugs are associated with a substantial QT-interval prolongation. The exact cause and its clinical relevance are, however, unclear. Nevertheless, an association between postoperative QT prolongation and risk for torsades de pointes is likely.
