Improving hepatitis B vaccination rates for advanced chronic kidney disease patients: a quality improvement initiative.

INTRODUCTION: Chronic kidney disease (CKD) patients are vulnerable to hepatitis B, and immunization prior to end stage kidney disease is recommended to optimize seroconversion. Our institution undertook a process improvement approach to increase hepatitis B vaccination in stage 4 and 5 CKD patients. METHODS: Four strategies were utilized such as: (1) Electronic health record (EHR)-based CKD registry to identify patients, (2) EHR-based physician/nurse reminders, (3) a co-located nurse appointment for vaccine administration, and (4) information sharing and provider awareness effort. The CKD registry was utilized to identify patients with stage 4 or 5 CKD, with at least two clinic visits in the prior 2 years, who had not received the hepatitis B vaccine or did not have serologic evidence of immunity. Target monthly vaccination rate was set at 75%, based on clinic leadership, nephrologist, and nurse consensus. RESULTS: A total of 239 patients were included in the study period, from November 2018 to January 2019 (observation period) and from February 2019 to September 2019 (intervention period). Monthly vaccination rate improved from 48% in November 2018 to the target rate of 75% by the end of the intervention (August and September 2019). There was a statistically significant increase from the rate of vaccination at a unique patient level in the first month of the baseline period, compared to the last month of the intervention period (51 vs. 75% p = 0.03). CONCLUSIONS: Utilizing a nurse-led approach to hepatitis B vaccination, coupled with EHR-based tools, along with continuous monitoring of performance, helped to improve hepatitis B vaccination among CKD stage 4 and 5 patients.

Well-differentiated papillary mesothelioma of the uterine serosa identified at cesarean section: a case report.

BACKGROUND: Peritoneal mesotheliomas encompass a variety of benign and malignant neoplasms. Well-differentiated papillary mesothelioma (WDPM) is uncommon, is thought to be of low malignant potential and is often discovered incidentally during abdominal or pelvic surgery. We describe a highly unusual case in which WDPM arising from the uterine serosa was identified at the time of cesarean delivery. CASE: A 21-year-old primigravida underwent cesarean delivery at term for arrest of the active phase of labor. A 2-cm, polypoid lesion was excised from the posterior uterine fundus; final pathology showed well-differentiated papillary mesothelioma. Subsequent examination and computed tomography were negative. A follow-up laparoscopic examination with abdominal washing for cytology and peritoneal biopsies revealed no residual disease. CONCLUSION: Survey of the pelvic cavity during cesarean section is important. Knowledge of the variable disease spectrum of mesothelioma is important in patient counseling and management. Differentiating between WDPM and malignant mesothelioma, other peritoneal tumors and implants from primary sites is necessary to avoid overtreatment.
