Clinical decision support system to optimise symptom management in palliative medicine: focus group study.

OBJECTIVES: Suboptimal symptom control in patients with life-limiting illnesses is a major issue. A clinical decision support system (CDSS) that combines a patient-reported symptom assessment scale (SAS) and guideline-based individualised recommendations has the potential to improve symptom management. However, lacking end-user acceptance often prevents CDSS use in daily practice.We aimed to evaluate the acceptability and feasibility of a palliative care CDSS according to its targeted end-users. METHODS: Six focus groups with different groups of stakeholders were conducted: (1) patient representatives; (2) community nurses; (3) hospital nurses; (4) general practitioners; (5) hospital physicians and (6) palliative care specialists. Audiotapes were transcribed verbatim and thematically analysed. RESULTS: Fifty-one stakeholders (6-12 per focus group) participated. Six themes were discussed: effect, validity, continuity, practical usability, implementation and additional features. All participants expected a CDSS to improve symptom management, for example, by reminding clinicians of blind spots and prompting patient participation. They feared interference with professional autonomy of physicians, doubted the validity of using a patient-reported SAS as CDSS input and thought lacking care continuity would complicate CDSS use. Clinicians needed clear criteria for when to use the CDSS (eg, life-limiting illness, timing in illness trajectory). Participants preferred a patient-coordinated system but were simultaneously concerned patients may be unwilling or unable to fill out an SAS. CONCLUSIONS: A palliative care CDSS was considered useful for improving symptom management. To develop a feasible system, barriers for successful implementation must be addressed including concerns about using a patient-reported SAS, lacking care continuity and unclear indications for use.

Molecular markers and clinical behavior of uterine carcinosarcomas: focus on the epithelial tumor component.

Carcinosarcomas (malignant mixed Müllerian tumors) of the uterus are rare and aggressive malignancies consisting of an epithelial (carcinoma) and a mesenchymal (sarcoma) tumor component and are considered as metaplastic endometrial carcinomas. This study evaluated molecular characteristics and clinical behavior of uterine carcinosarcomas to improve treatment regimens in the future. Immunohistochemical expression of estrogen receptor-α and -ß, progesterone receptor-A and -B, MLH1, MSH2, MSH6, PTEN (phosphatase and tensin homolog deleted on chromosome 10), p53, ß-catenin and cyclin D1 was determined in 40 uterine carcinosarcomas. Immunostaining was compared between epithelial and mesenchymal tumor components. To determine the prognostic role of the epithelial component, clinicopathological data and survival were compared between patients with endometrioid and non-endometrioid epithelial tumor components. To determine prognosis of carcinosarcomas compared with high-risk endometrial carcinomas, clinicopathological characteristics and survival were compared between these patients. Hormone receptor expression occurred infrequently: estrogen receptor-α (8%) and -ß (32%), progesterone receptor-A (0%) and -B (23%), next to ß-catenin (4%) and cyclin D1 (7%). PTEN, MLH1, MSH2 and MSH6 mutations occurred in 39%, 33%, 22% and 21%, respectively (based on absent immunostaining). Overexpression of p53 was observed in 38%. Expression patterns of p53, MSH2 and MSH6 corresponded between epithelial and mesenchymal tumor components. In our cohort, the epithelial component caused the majority of metastases (72%) and vascular invasion (70%). Survival tended to be worse for patients with a non-endometrioid epithelial component compared with an endometrioid epithelial component (5-year survival: 26% and 55%, respectively). Survival was worse for patients with uterine carcinosarcomas compared with high-risk endometrial carcinomas (grade 3 endometrioid and non-endometrioid); 5-year survival rates: 42%, 77% and 57%, respectively. Our results support the monoclonal origin of uterine carcinosarcomas. The epithelial component determines prognosis by causing the majority of metastases and vascular invasion. To improve prognosis, treatment should focus on the epithelial tumor component of uterine carcinosarcomas.
