Perbandingan Tingkat Kecemasan dan Kualitas Tidur pada Pasien Pra dan Pasca Operasi di RSUD Dr. H. Soewondo Kendal

Anxiety and sleep quality are two closely related aspects in patients undergoing surgical procedures. High levels of anxiety in the preoperative phase often result in decreased sleep quality, while poor sleep can exacerbate anxiety, thus affecting the postoperative recovery process. This study aims to compare anxiety levels and sleep quality in patients before and after surgery. The research design used was a quasi-experimental with a pre-post test approach. The study sample consisted of 119 respondents selected through a purposive sampling technique in the Kenanga Ward of Dr. H. Soewondo Kendal Regional Hospital. The instruments used included the Zung Self-Rating Anxiety Scale (SAS) questionnaire to measure anxiety levels and the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality. Data were analyzed using the Chi-Square test with the help of SPSS version 25 software. The results showed a significant relationship between anxiety levels and sleep quality in both the pre- and postoperative phases (p = 0.000; p < 0.05). A total of 54.4% of patients with poor sleep quality before surgery showed improvement after surgery. Furthermore, in the group with moderate anxiety, 54.8% experienced a reduction to mild anxiety. In conclusion, reducing anxiety levels has been shown to positively impact patients' sleep quality after surgery.
