Disentangling symptoms of externalizing disorders in children using multiple measures and informants.

The trait impulsivity theory suggests that a single, highly heritable externalizing liability factor, expressed as temperamental trait impulsivity, represents the core vulnerability for externalizing disorders. The present study sought to test the application of latent factor models derived from this theory to a clinical sample of children. Participants were 474 German children (age 6-12 years, 81% male) with symptoms of attention-deficit/hyperactivity disorder and externalizing behavior problems participating in an ongoing multicenter intervention study. Using confirmatory factor analyses (CFA) and exploratory structural equation modeling (ESEM), we evaluated several factor models of externalizing spectrum disorders (unidimensional; first-order correlated factors; higher-order factor; fully symmetrical bifactor; bifactor S-1 model). Furthermore, we assessed our prevailing factor models for measurement invariance across raters (clinicians, parents, teachers) and assessment modes (interview, questionnaires). While both CFA and ESEM approaches provided valuable insights into the multidimensionality, ESEM solutions were generally superior since they showed a substantially better model fit and less biased factor loadings. Among the models tested, the bifactor S-1 CFA/ESEM models, with a general hyperactivity-impulsivity reference factor, displayed a statistically sound factor structure and allowed for straightforward interpretability. Furthermore, these models showed the same organization of factors and loading patterns, but not equivalent item thresholds across raters and assessment modes, highlighting cross-situational variability in child behavior. Our findings are consistent with the assumption of the trait impulsivity theory that a common trait, presented as hyperactivity-impulsivity symptoms, underlies all externalizing disorders.

Analysing the impact of a case management model on the specialised palliative care multi-professional team.

PURPOSE: Palliative care (PC) involves many health care providers leading to a high complexity of structures that requires efficient coordination as provided by case management (CM). Our study aimed to evaluate the effects of CM newly implemented in a specialised palliative care unit by evaluating team members' tasks and time resources before (T0) and after implementation (T1). It was hypothesised that team members would be able to spend less time on organisational and administrative tasks and more time on patient care. METHODS: A prospective pre-post study design was used. Time distribution of different tasks at T0 and T1 was compared between three different professional groups: physicians, nursing staff and social work. To document their tasks and time required, a documentation form with several items for each profession was developed. Data was analysed using t tests for independent samples. RESULTS: After Bonferroni correction, a significant pre-post difference was found for the time spent on "discharge interview and discharge" as rated by the physicians (p < .001) with less time spent on this activity after CM implementation. The nursing staff had significantly more time for "conversations with patients" (p < .001) after CM implementation. Moreover, they spent significantly less time on "patient-related requests/advice by telephone" (p < .001) and "discussions with relatives/participation in family discussions" at post-assessment (p < .001). The social worker had significantly more time for "patient advice and support services" (p = .013) after CM implementation. CONCLUSIONS: Integrating CM can be time efficient and ensures team members to spend more time on their core tasks in patient care.

Identifying patients suitable for palliative care--a descriptive analysis of enquiries using a Case Management Process Model approach.

BACKGROUND: In Germany, case management in a palliative care unit was first implemented in 2005 at the Department of Palliative Medicine at the University Hospital Cologne. One of the purposes of this case management is to deal with enquiries from patients and their relatives as well as medical professionals. Using the Case Management Process Model of the Case Management Society of America as a reference, this study analysed (a) how this case management was used by different enquiring groups and (b) how patients were identified for case management and for palliative care services. The first thousand enquiries were analysed considering patient variables, properties of the enquiring persons and the content of the consultations. RESULTS: Most enquiries to the case management were made by telephone. The majority of requests regarded patients with oncological disease (84.3 %). The largest enquiring group was composed of patients and relatives (40.8 %), followed by internal professionals of the hospital (36.1 %). Most of the enquiring persons asked for a patient's admission to the palliative care ward (46.4 %). The second most frequent request was for consultation and advice (30.9 %), followed by requests for the palliative home care service (13.3 %). Frequent reasons for actual admissions were the need for the treatment of pain, the presence of symptoms and the need for nursing care. More than half of the enquiries concerning admission to the palliative care ward were followed by an admission. CONCLUSIONS: Case management has been made public among the relevant target groups. Case management as described by the Case Management Process Model helps to identify patients likely to benefit from case management and palliative care services. In addition, with the help of case management palliative patients may be allocated to particular health care services.
