The effect of provision of information on serum cortisol in patients transferred from the coronary care unit to the general ward: A randomised controlled trial

The effect of education on pre-operative anxiety in patients undergoing extracorporeal shock wave lithotripsy

BACKGROUND

The period before diagnostic and therapeutic procedures is associated with increased anxiety levels in patients due to a lack of sufficient information. This study aimed to determine the effect of education on physiological and psychological anxiety levels in patients before extracorporeal shock wave lithotripsy (ESWL).

MATERIALS AND METHODS

This randomized clinical trial was conducted at Baharloo Hospital in Tehran on 122 patients, and the samples were selected in two stages. In the first stage, the samples were selected using convenience sampling. In the second stage, they were randomly assigned to the intervention and control groups. The data were collected using demographic information and Spielberger's State-Trait Anxiety Inventory to measure psychological anxiety. Salivary cortisol was measured to evaluate physiological anxiety by both groups before the intervention and entering the room. The intervention group received the information before ESWL via face-to-face lectures and the broadcast of pre-recorded lecture videos. The control group received only the usual care in the ward. The data analysis was performed by SPSS version 25 using descriptive statistics that included the calculation of mean, standard deviation, and frequency distribution and inferential statistics (independent t-test, paired t-test ANOVA, and Chi-square test).

RESULTS

There was no significant difference in demographic characteristics between the intervention and control groups (P > 0.05). A significant decrease in the mean salivary cortisol level was found in the intervention group compared with the control group (P < 0.001). The anxiety level was markedly decreased in the intervention group compared with the control group (P < 0.001).

CONCLUSION

Adequately informing patients before ESWL could decrease patients' physiological and psychological anxiety levels. So, people in the field of nursing education can take an important step towards using this method and reducing the anxiety of patients. The existence of such videos and holding training sessions can be a suitable solution for educating the patient.

Evaluating the Effect of Preoperative Provision of Information on Salivary Cortisol in Patients Undergoing Breast Cancer Surgery: A Randomized Controlled Study

PURPOSE

Surgery is considered to be an anxious experience and most patients experience preoperative anxiety. Preoperative awareness has long been one of the most effective ways to reduce fear and anxiety caused by surgery. The aim of this study was to determine the effect of preoperative provision of information on salivary cortisol in candidates for breast cancer surgery.

DESIGN

This randomized clinical trial was conducted on 80 patients (divided into control group and intervention group; 40 patients in each group) admitted to the surgery department of the Cancer Institute of Imam Khomeini hospital in Iran. Samples were selected using random allocation method with a block size of four. Data were collected on participants' demographic characteristics and salivary cortisol.

METHODS

The educational intervention for patients in the control group was routine training and for patients in the intervention group was based on the training booklet approved by cancer specialists. Findings were analyzed using SPSS software version 21.

FINDINGS

The mean age of participants in the intervention and control groups was 44.00 ± 11.45 and 42.62 ± 12.83 years, respectively . The mean score of anxiety in the intervention group was 18.85± 6.19 before intervention, and decreased to 7.40± 3.68 after intervention . The mean score of anxiety in the control group was 19.75 ± 7.26 and significantly decreased to 14.25 ± 5.73 at the end of the study.

CONCLUSIONS

The results showed that preoperative anxiety significantly decreased in both groups, but was lower overall in the intervention group. In fact, using an educational booklet to raise awareness about patients' health, surgery knowledge and postoperative care as well as how to adapt to postsurgery physical changes and to promote psychological support can reduce patients' anxiety. Hence, providing education to patients may be integrated as a complementary method in patients' routine education.
