Peplau's interpersonal relationship theory combined with bladder function training on patients with prostate cancer

Prostate cancer is a major disease impacting men's health worldwide. Peplau, who is known as "the mother of psychiatric society," developed an interpersonal relationship theory for nursing. Implementation of this theory in practice has been shown to positively impact patients' quality of life and reduce adverse symptoms after surgery.

To investigate the effects of a nursing model based on Peplau's interpersonal relationship theory combined with bladder function training on patients with prostate cancer.

Eighty-nine patients with prostate cancer who underwent transurethral resection of the prostate (TURP) participated in this study. These patients were admitted to The First Affiliated Hospital of Soochow University or Dushu Lake Hospital Affiliated to Soochow University between January 2020 and April 2021. Patients were randomized into either the Peplau nursing group (n = 44) or a routine nursing group (n = 45). The routine nursing group received routine care and bladder function training, while the Peplau care group received care that integrated concepts from the Peplau interpersonal relationship theory as well as bladder function training. The urinary incontinence symptoms of the two groups were recorded, and the respective International Prostate Symptom Scores (IPSS), Functional Assessment of Chronic Illness Therapy- Spiritual Well-Being (FACIT-Sp) scores, and quality of life (QOL) scores for each group were compared before and after three months of nursing intervention.

During the intervention period, the duration of urinary incontinence, frequency, number and amount of urinary incontinence were significantly greater in the routine nursing group compared to the Peplau care group (P < 0.05). The indicators of the routine nursing group were 7.13 ± 2.42 days, 8.23 ± 2.75 times, and 1.24 ± 0.42 L, while those of the Peplau care group were 4.74 ± 1.85 d, 4.21 ± 1.26 times, and 0.56 ± 0.11 L, respectively. After three months of intervention, the mean IPSS score of the routine nursing group was significantly reduced (P < 0.05), while the mean FACIT-Sp and QOL scores were significantly increased (P < 0.05). The mean IPSS score in the Peplau nursing group was significantly lower compared to the routine nursing group, while the FACIT-Sp and QOL scores were higher (P < 0.05).

A nursing model based on Peplau's interpersonal relationship theory combined with bladder function training can significantly improve prostate function and urinary symptoms, resulting in the restoration of physiological function and improvement in the QOL of patients with prostate cancer following TURP.
