Patient satisfaction during radiation therapy. Correlates and patient suggestions.

BACKGROUND: Assessing patient satisfaction might help to detect so far unknown patient needs and could contribute to quality assurance within the health care system. We evaluated patient satisfaction and its correlates in a consecutive sample of patients undergoing external beam radiation therapy. PATIENTS AND METHODS: Patient satisfaction was evaluated within a prospective study with two validated instruments (FPZ, ZUF-8) during the first week of radiation therapy in two university-based radiation oncology departments. RESULTS: A total of 273 patients could be analyzed. Most patients were irradiated for breast or urogenital cancer. Overall patient satisfaction was high (94.9-98.8%). The most important items for patient satisfaction included the following: "skills of physicians" followed by "physician contact with patients," "care," and "information" (Tab. 2). Neither center nor disease entity correlated with global patient satisfaction. Of the patients, 46% reported that they would have preferred additional information prior to the onset of radiotherapy. Patients who sought additional information reported a lower global patient satisfaction (p < 0.001). In multiple linear regression analysis, the need for more information, male gender, and a higher level of education were significant predictors for lower global patient satisfaction (Tab. 6). CONCLUSION: During the first week of radiation therapy, patients rate patient-physician interaction and communication on treatment and disease as important factors for their satisfaction. Supplying additional information to subsets of patients prior to starting radiotherapy might help to further improve satisfaction.

Plasma levels of endothelin-1 in patients with the hepatorenal syndrome after successful liver transplantation.

The hepatorenal syndrome (HRS) is characterized by renal vasoconstriction leading to deterioration of renal function in patients with liver disease. A possible role of endothelin-1 (ET-1) in the pathogenesis of HRS has been suggested, but a correlation between ET-1 plasma levels and the development of HRS as well as the recovery from HRS following OLT has not been shown yet. We performed longitudinal measurements of ET-1 plasma levels in four groups of patients, 5 patients with HRS before and after orthotopic liver transplantation (OLT), 10 patients without HRS undergoing OLT, 20 patients with chronic renal failure but without liver disease, and 12 healthy controls. Before OLT, plasma levels of ET-1 were higher in patients with HRS (19.5 +/- 8.6 ng/l, P < 0.001; n = 5) compared to patients without HRS (4.9 +/- 1.1 ng/l; n = 10), normals (1.2 +/- 0.18 ng/l; n = 12), and patients with chronic renal failure (2.4 +/- 0.4 ng/l; n = 20). Patients with HRS compared to patients without HRS had higher levels for creatinine (2.42 +/- 0.6 vs. 0.89 +/- 0.05 mg/dl, P < 0.05), creatinine clearance (107 +/- 9 ml/min vs. 44.6 +/- 5.5 ml/ min, P < 0.001), and bilirubin (11.4 +/- 3.8 vs. 3.7 +/- 1 mg/dl, P < 0.05) before OLT. Within one week after OLT, there was a rapid decrease in ET-1 levels in patients with HRS while creatinine and bilirubin levels decreased slower. Regression analysis revealed a weak correlation between serum creatinine and ET-1 (r = 0.192, P = 0.04) and a significant correlation between serum bilirubin and ET-1 (r = 0.395, P < 0.001). The means of the ET-1 levels decreases rapidly with improvement of liver function after OLT. Levels of ET-1 correlate with excretory liver function assessed by bilirubin. The fall in ET-1 levels preceding improvement of renal function further strengthens the concept of ET-1 being a causative factor in HRS.
