Readmissions related to antihypertensive medications used in chronic hemodialysis

Background: In hemodialysis, hypertension is treated by removing excess fluid and antihypertensive therapy. Commonly, the antihypertensives used to treat hypertension in earlier stages of kidney disease are continued as the patient progresses into end-stage renal disease and begins dialysis, without much evidence for benefit. Methods: This study is a single center, retrospective chart review that included hemodialysis patients admitted for congestive heart failure (CHF), fluid overload, or pulmonary edema as determined by ICD-9 code (428.x, 276.6, 518.4, 506.1). The primary objective was to determine if the number or class of antihypertensives used in the chronic hemodialysis population increased the number of readmissions related to CHF, fluid overload, or pulmonary edema. Patients were separated into two groups based on total number of antihypertensive medications, less than or equal to 2 medications for group 1 and greater than two medications for group 2. The primary endpoint was 30-day readmission for CHF, fluid overload, or pulmonary edema. Results: For the study period, 85 individual patient charts met inclusion criteria. Group 1 (n?=?44) experienced seven readmissions (16%) and group 2 (n?=?41) experienced eight readmissions (18%) (p?=?0.663). The most common antihypertensives at discharge were ACE inhibitors for group 1 (45%) and dihydropyridine calcium channel blockers for group 2 (66%). No difference in systolic blood pressures before, during and after hemodialysis was found between groups. Conclusions: Antihypertensive medications continue to play an important role in the hemodialysis population. This study suggests that drug class and quantity of antihypertensives do not alter readmission rate in the setting of fluid overload.     

Effects of an early referral system on liver transplantation for hepatoblastoma at Texas Children's Hospital

The purposes of this study were to analyze the effects of an ERS on time to transplantation and to describe our center's experience with OLT for HB. Patients who received OLT for HB between 2000 and 2013 were included. Patient and allograft characteristics, chemotherapy regimens, and prior surgical therapies were examined. The interval between diagnosis and OLT prior to and following the institution of an ERS for transplant was compared. Survival and tumor recurrence were analyzed. Nineteen patients received OLT for HB (mean age 33 months). All children received grafts from deceased donors. Two patients underwent prior resections. Tumor recurred in four patients (21.1%). Both patients who received salvage transplants experienced post‐OLT recurrence. Three of the four recurrences occurred in spite of adjuvant chemotherapy. There were three deaths: two from metastatic disease. One‐ and five‐yr survivals were 86.1% and 73.8%. After the institution of the ERS, the mean interval between tissue diagnosis and OLT was significantly reduced. Our series of 19 patients demonstrates a 21% recurrence of HB following OLT despite chemotherapy. Five‐yr survival reached 73.8%. A system of early referral can effectively reduce times between diagnosis and transplant.
