Standardized measures to evaluate neurological patients in palliative care are missing. The Integrated Palliative Outcome Scale, a self-report tailored for neurological patients (IPOS Neuro-S8) helps identify symptom burden but lacks validation in German. This study aimed to validate the IPOS Neuro-S8 in severely affected multiple sclerosis (MS) patients.
Methods
This validation study is a secondary analysis of data from a clinical phase II intervention study with severely affected MS patients. The original study enrolled German-speaking patients aged 18 with severe MS who receive an escalating immunotherapeutic agent and/or exhibit a high level of disability were recruited from the administrative district Cologne (#DRKS00021783). In this validation study, we evaluated construct, discriminant, and convergent validity, internal consistency, test–retest reliability, and sensitivity to change of the IPOS Neuro-S8, using the “Hamburger Lebensqualitätsmessinstrument” (HALEMS), and the Hospice and Palliative Care Evaluation supplemented by neurological symptoms (HOPE+) as comparison measures.
Results
Data from 80 MS patients (mean age 56, SD = 11) were analyzed. Exploratory and confirmatory factor analyses revealed a 3-factor structure (r = 0.34–0.63), reflecting distinct clinical patterns, i.e., breath-mouth connection, pain-sleep cycle, and nausea-vomiting link. Significant convergent validity to hypothesized total score of the HOPE+ (rs(78) = 0.71, p < 0.001) and good discriminant validity using the HALEMS total score (rs(78) = 0.48, p < 0.001) were observed. Correlation with physical symptoms of the HALEMS was stronger than with nonphysical aspects. Internal consistency (Cronbach’s α = 0.67) and test–retest reliability (intraclass coefficient = 0.75) were acceptable.
Significance of results
IPOS Neuro-S8 displays promising psychometric properties for assessing palliative care symptoms in severe MS, a model for other severe neurological diseases due to MS's broad central nervous involvement, allowing findings to be transferable to other neurological diseases. A criterion for minimal clinically important difference was established to evaluate the sensitivity to change. Additional validation across different neurological conditions and disease severities is warranted to enhance generalizability and clinical utility.
Patients with metastatic upper gastrointestinal (GI) cancer may experience a large physical symptom burden. However, less is known about existential, social, and psychological symptoms. To provide the patient with palliative care, quality-of-life questionnaires are used for structured needs assessment. These are sporadically implemented, and there seems to be uncertainty to the efficiency of current practice. The aim of study was to explore the experienced assessment-process and treatment of palliative symptoms, as well as the experienced symptom burden, in patients with metastatic upper GI cancer.
Methods
Qualitative, semi-structured interviews were conducted in 10 patients with metastatic upper GI cancer. Data were analyzed using content analysis.
Results
The patients did not expect treatment for all physical symptoms. Existential symptoms revolved around death and dying, social issues were mainly related to family, and psychological issues were based in the continuous dealing with serious illness. Existential, social, and psychological symptoms were mostly not considered part of the expected care when admitted to hospital. Patients had only vague recollections of their experiences with structured needs assessment, and the process had been inconsequential in the treatment of symptoms.
Significance of results
Patients with upper GI cancer experience symptoms related to all 4 areas of palliative care being physical, existential, social, and psychological, but these are differentiated in the way patients perceive their origins and treatability. Structured needs assessment was not routinely carried out, and in cases where this had been done, no follow-up was effectuated. This calls for increased focus and proper implementation for the process to be relevant in the treatment of palliative symptoms.
