Personal dignity in the terminally ill from the perspective of caregivers : a survey among trained volunteers and physicians

Background: Although dignity is increasingly considered a goal of palliative care, little research has evaluated the understanding of dignity at the end of life from a caregiver's perspective. Objective: The study objective was to investigate and compare the views of trained volunteers and SCEN physicians on maintaining dignity for patients reaching the end of life. Design: The study is a survey questionnaire study. Subjects: Subjects were two groups of caregivers involved in care for dying patients: trained volunteers (n=236) and end-of-life consultants (SCEN physicians; n=427). Measurements: Measurement was done via the Dutch version of the 22-item Patient Dignity Inventory on symptoms and experiences that have been shown to influence the sense of dignity in terminally ill patients. Respondents were asked to rate on a five-point scale the extent to which they considered the items as influential on dignity in terminally ill patients, and as problematic in practice in maintaining dignity for patients in the last phase of life. Results: Overall, volunteers indicated items more frequently as influential to dignity and as problematic in maintaining dignity at the end of life, compared to SCEN physicians. Volunteers gave significantly higher ratings than SCEN physicians to most of the social items, and to half of the psychological and existential items. Conclusions: It seems that SCEN physicians consider the physical aspects of suffering to be most influential and problematic in practice in preserving dignity, while volunteers think psychosocial aspects are most important in preserving dignity at the end of life. These findings suggest that the role and responsibilities of caregivers involved in care for terminally ill patients affect the factors that they think influence dignity

Analysis of the construct of dignity and content validity of the patient dignity inventory

<p>Abstract</p> <p>Background</p> <p>Maintaining dignity, the quality of being worthy of esteem or respect, is considered as a goal of palliative care. The aim of this study was to analyse the construct of personal dignity and to assess the content validity of the Patient Dignity Inventory (PDI) in people with an advance directive in the Netherlands.</p> <p>Methods</p> <p>Data were collected within the framework of an advance directives cohort study. This cohort study is aiming to get a better insight into how decisions are made at the end of life with regard to advance directives in the Netherlands. One half of the cohort (n = 2404) received an open-ended question concerning factors relevant to dignity. Content labels were assigned to issues mentioned in the responses to the open-ended question. The other half of the cohort (n = 2537) received a written questionnaire including the PDI. The relevance and comprehensiveness of the PDI items were assessed with the COSMIN checklist ('COnsensus-based Standards for the selection of health status Measurement INstruments').</p> <p>Results</p> <p>The majority of the PDI items were found to be relevant for the construct to be measured, the study population, and the purpose of the study but the items were not completely comprehensive. The responses to the open-ended question indicated that communication and care-related aspects were also important for dignity.</p> <p>Conclusions</p> <p>This study demonstrated that the PDI items were relevant for people with an advance directive in the Netherlands. The comprehensiveness of the items can be improved by including items concerning communication and care.</p

Impact of partial-volume correction in oncological PET studies:A systematic review and meta-analysis

Purpose: Positron-emission tomography can be useful in oncology for diagnosis, (re)staging, determining prognosis, and response assessment. However, partial-volume effects hamper accurate quantification of lesions &lt;2–3× the PET system’s spatial resolution, and the clinical impact of this is not evident. This systematic review provides an up-to-date overview of studies investigating the impact of partial-volume correction (PVC) in oncological PET studies.Methods: We searched in PubMed and Embase databases according to the PRISMA statement, including studies from inception till May 9, 2016. Two reviewers independently screened all abstracts and eligible full-text articles and performed quality assessment according to QUADAS-2 and QUIPS criteria. For a set of similar diagnostic studies, we statistically pooled the results using bivariate meta-regression.Results: Thirty-one studies were eligible for inclusion. Overall, study quality was good. For diagnosis and nodal staging, PVC yielded a strong trend of increased sensitivity at expense of specificity. Meta-analysis of six studies investigating diagnosis of pulmonary nodules (679 lesions) showed no significant change in diagnostic accuracy after PVC (p = 0.222). Prognostication was not improved for non-small cell lung cancer and esophageal cancer, whereas it did improve for head and neck cancer. Response assessment was not improved by PVC for (locally advanced) breast cancer or rectal cancer, and it worsened in metastatic colorectal cancer.Conclusions: The accumulated evidence to date does not support routine application of PVC in standard clinical PET practice. Consensus on the preferred PVC methodology in oncological PET should be reached. Partial-volume-corrected data should be used as adjuncts to, but not yet replacement for, uncorrected data.</p
