Evaluating the perceived added value of a threefold intervention to improve palliative care for persons experiencing homelessness:A mixed-method study among social service and palliative care professionals

BACKGROUND: Palliative care for persons experiencing homelessness who reside in social service facilities is often late or lacking. A threefold intervention was implemented to improve palliative care for this population by increasing knowledge and collaboration between social service and palliative care professionals. This consultation service comprised: 1) consultations between social service professionals and palliative care professionals; 2) multidisciplinary meetings involving these professionals; and 3) training of these professionals. This study aims to evaluate the perceived added value of this threefold consultation service in three regions in the Netherlands. METHODS: A mixed-methods evaluation study using structured questionnaires for consultants, requesting consultants, and attendees of multidisciplinary meetings, semi-structured group and individual interviews with social service and palliative care professionals involved, weekly diaries filled out by consultants, and an implementation diary. Qualitative data were analyzed following the principles of thematic analysis. Quantitative data were analyzed descriptively. RESULTS: Thirty-four consultations, 22 multidisciplinary meetings and 9 training sessions were studied during the implementation period of 21 months. Social service professionals made up the majority of all professionals reached by the intervention. In all regions the intervention was perceived to have added value for collaboration and networks of social service and palliative care professionals (connecting disciplines reciprocally and strengthening collaborations), the competences of especially social service professionals involved (competency in palliative care provision, feeling emotionally supported in complex situations), and the quality and timing of palliative care (more focus on quality of life and dying, advance care planning and looking ahead, and greater awareness of death and palliative care). CONCLUSIONS: The threefold consultation service particularly helps social service professionals connect with palliative care professionals. It helps them to identify palliative care needs in good time and to provide qualitatively better palliative care to persons experiencing homelessness

A Normalized Tree Index for identification of correlated clinical parameters in microarray experiments

Martin C, Tauchen A, Becker A, Nattkemper TW. A Normalized Tree Index for identification of correlated clinical parameters in microarray data. BioData Mining. 2011;4(1): 2.BACKGROUND: Measurements on gene level are widely used to gain new insights in complex diseases e.g. cancer. A promising approach to understand basic biological mechanisms is to combine gene expression profiles and classical clinical parameters. However, the computation of a correlation coefficient between high-dimensional data and such parameters is not covered by traditional statistical methods. METHODS: We propose a novel index, the Normalized Tree Index (NTI), to compute a correlation coefficient between the clustering result of high-dimensional microarray data and nominal clinical parameters. The NTI detects correlations between hierarchically clustered microarray data and nominal clinical parameters (labels) and gives a measurement of significance in terms of an empiric p-value of the identified correlations. Therefore, the microarray data is clustered by hierarchical agglomerative clustering using standard settings. In a second step, the computed cluster tree is evaluated. For each label, a NTI is computed measuring the correlation between that label and the clustered microarray data. RESULTS: The NTI successfully identifies correlated clinical parameters at different levels of significance when applied on two real-world microarray breast cancer data sets. Some of the identified highly correlated labels confirm the actual state of knowledge whereas others help to identify new risk factors and provide a good basis to formulate new hypothesis. CONCLUSIONS: The NTI is a valuable tool in the domain of biomedical data analysis. It allows the identification of correlations between high-dimensional data and nominal labels, while at the same time a p-value measures the level of significance of the detected correlations

Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples

Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

Attractiveness of people-centred and integrated Dutch Home Care: A nationwide survey among nurses

The World Health Organization is calling for a fundamental change in healthcare services delivery, towards people‐centred and integrated health services. This includes providing integrated care around people′s needs that is effectively co‐ordinated across providers and co‐produced by professionals, the patient, the family and the community. At the same time, healthcare policies aim to scale back hospital and residential care in favour of home care. This is one reason for the home‐care nursing staff shortages in Europe. Therefore, this study aimed to examine whether people‐centred, integrated home care appeals to nurses with different levels of education in home care and hospitals. A questionnaire survey was held among registered nurses in Dutch home‐care organisations and hospitals in 2015. The questionnaire addressed the perceived attractiveness of different aspects of people‐centred, integrated home care. In total 328 nurses filled in the questionnaire (54% response rate). The findings showed that most home‐care nurses (70% to 97%) and 36% to 76% of the hospital nurses regard the different aspects of people‐centred, integrated home care as attractive. Specific aspects that home‐care nurses find attractive are promoting the patient′s self‐reliance and having a network in the community. Hospital nurses are mainly attracted to health‐related prevention and taking control in complex situations. No clear differences between the educational levels were found. It is concluded that most home‐care nurses and a minority of hospital nurses feel attracted to people‐centred, integrated home care, irrespective of their educational level. The findings are relevant to policy makers and home‐care organisations who aim to expand the home‐care nursing workforce

Home-care nursing staff in self-directed teams are more satisfied with their job and feel they have more autonomy over patient care: a nationwide survey

Aims The aims of this study were: (1) To examine whether working in a self-directed team is related to home-care nursing staff's job satisfaction; (2) To assess the mediating effect of self-perceived autonomy over patient care; (3) To investigate the moderating effect of educational level on the association between autonomy over patient care and job satisfaction. Background Self-directed teams are being introduced in home care in several countries. It is unknown whether working in a self-directed team is related to nursing staff's job satisfaction. It is important to gain insight into this association since self-directed teams may help in retaining nursing staff. Design A cross-sectional study based on two questionnaire surveys in 2014 and 2015. Methods The study involved 191 certified nursing assistants and registered nurses employed in Dutch home-care organizations (mean age of 50). These were members of the Dutch Nursing Staff Panel, a nationwide panel of nursing staff working in various healthcare settings. Results Self-direction is positively related to nursing staff's job satisfaction. This relationship is partly mediated by autonomy over patient care. For certified nursing assistants and registered nurses with a bachelor's degree, a greater sense of autonomy over patient care in self-directed teams is positively related to job satisfaction. No significant association was found between autonomy over patient care and job satisfaction for registered nurses with an associate degree. Conclusions This study suggests that home-care organizations should consider the use of self-directed teams as this increases nursing staff's job satisfaction and may therefore help to retain nursing staff in home care

Is Information Provision about Benefits and Risks of Treatment Options Associated with Receiving Person-Centered Care?: A Survey among Incurably Ill Cancer Patients

Background: Cancer patients with advanced disease are confronted with increasingly complex life-prolonging/symptom-relieving treatment decisions. Being informed of treatment benefits and risks is important, but information provision might be suboptimal. Objective: To assess the extent to which patients with incurable cancer feel informed about benefits and risks of possible treatments, and whether this relates to their self-perceived receipt of person-centered care. Methods: Patients with incurable cancer (N = 212) reported the degree to which they felt informed about treatment benefits/risks. Person-centered care was operationalized as "feeling involved in care" and "feeling that preferences were taken into account". (Logistic) regression analyses assessed the relationship between feeling informed and receiving person-centered care, exploring moderating influences of background characteristics. Results: Two-thirds (66%) of patients felt incompletely informed about treatment benefits/risks. Two-thirds (65%) of patients felt that they were always involved in their care, and 60% felt their preferences were taken into account by all providers. If patients felt completely informed, they also felt they received more person-centered care (p = < 0.01). Seventy six percent and 81% of completely informed versus 58% and 50% of incompletely informed patients felt that they were, respectively, always involved and that preferences were taken into account by all providers. Background characteristics did not moderate these relationships, but influenced perceptions of received information and person-centered care. Conclusions: Complete information provision about treatment benefits and risks is, according to patients, not commonplace. Yet such information is related to receiving person-centered care. More research into what specific information is preferred, provided, and remembered is warranted, to achieve optimal person-centered care
