Organizing for sustainable inter-organizational collaboration in health care processes

ABSTRACT

Integrating health care services has proven to be important from both the patient and organizational perspectives. This study explores what defines a perceived well-functioning collaboration in the inter-organizational process of providing assistive devices in Sweden. Two focus groups comprising participants with profound knowledge of collaboration were performed, and data were analyzed in five steps, resulting in a data structure. Results yield the identification of three interacting processes: coordinating efforts to patient needs, ensuring evidence-based practice, and planning for efficient use of resources. These processes affected one another, and, therefore, would likely not have been effectively managed separately. The study contributes to theories of process management and organization by specifically focusing on how to analyze and improve sustainable collaboration in health care processes at both the management and professional levels. Theoretical frameworks that show different ways of organizing collaboration, as well as the concepts of action nets and boundary objects, can support both analysis and planning of collaboration. The intention would be to develop integration in inter-organizational health care processes, resulting in more person-centered care.     

An evaluation of zonisamide,including its long-term efficacy,for the treatment of focal epilepsy

Introduction: About 70 million people worldwide are estimated to suffer from epilepsy. Despite a large variety of old and new antiepileptic drugs on the market, about 30% of people with epilepsy do not become seizure-free with medical treatment. This is a major individual and public health burden. Most of these difficult-to-treat patients are having focal seizures. Zonisamide is effective against focal seizures in adults and children and, thus, a therapeutic option for such patients. Its safety profile needs special attention.

Areas covered: Herein, the authors discuss the pharmacology, clinical efficacy and the adverse effects of zonisamide. The article is derived from clinical trial data, long-term studies, meta-analyses, review articles, text books, webpages, and official license information.

Expert opinion: Zonisamide has proven to be efficacious in focal epilepsy in children and adults, although it is not more effective than carbamazepine or other antiepileptic drugs. It is also effective in generalized epilepsy and in several other conditions of the CNS. Its safety profile may prevent it from becoming a first-line drug for focal epilepsy or any other indication.     

Infliximab in inflammatory bowel disease: clinical outcome in a population based cohort from Stockholm County

BACKGROUND: Several placebo controlled studies have demonstrated the efficacy of infliximab in inflammatory bowel disease (IBD) but the potential toxicity of this new biological compound has been less studied. AIM: To assess the use of infliximab in IBD in a population based cohort, with special emphasis on the occurrence of severe adverse events and mortality. PATIENTS: All patients with IBD treated with infliximab between 1999 and 2001 in Stockholm County were evaluated. METHODS: Prospective registration of clinical data was carried out. Retrospective analyses were made of possible adverse events occurring in relation to infliximab treatment. Adverse events requiring pharmacological treatment or hospitalisation were defined as severe. Clinical response was assessed as remission, response, or failure. RESULTS: A cohort comprising 217 patients was assembled: 191 patients had Crohn's disease (CD), and infliximab was used off label for ulcerative colitis (UC) in 22 patients. Four patients were treated for indeterminate colitis (IC). Mean age was 37.6 (0.9) years (range 8-79). The mean number of infliximab infusions was 2.6 (0.1) (range 1-11). Forty two severe adverse events were registered in 41 patients (CD, n = 35). Eleven of the severe adverse events occurred postoperatively (CD, n = 6). Three patients with CD developed lymphoma (of which two were fatal), opportunistic infections occurred in two patients (one with UC, fatal), and two patients with severe attacks of IBD died due to sepsis (one with CD, one postoperatively with UC). One additional patient with UC died from pulmonary embolism after colectomy. Mean age in the group with fatal outcome was 62.7 years (range 25-79). The overall response rate was 75% and did not differ between the patient groups. CONCLUSIONS: Infliximab was efficacious as an anti-inflammatory treatment when assessed in a population based cohort of patients with IBD. However, there appear to be a significant risk of deleterious and fatal adverse events, particularly in elderly patients with severe attacks of IBD. Off label use of infliximab in UC and IC should be avoided until efficacy is proven in randomised controlled trials. The underlying risk of developing malignancies among patients with severe or chronically active CD in need of infliximab treatment is not known but the finding of a 1.5% annual incidence of lymphoma emphasises the need for vigilant surveillance with respect to this malignant complication.     

Personal identity narratives of therapeutic songwriting participants following Spinal Cord Injury: A case series analysis

Context/Objective: Spinal Cord Injury (SCI) patients face unique identity challenges associated with physical limitations, higher comorbid depression, increased suicidality and reduced subjective well-being. Post-injury identity is often unaddressed in subacute rehabilitation environments where critical physical and functional rehabilitation goals are prioritized. Therapeutic songwriting has demonstrated prior efficacy in promoting healthy adjustment and as a means of expression for post-injury narratives. The current study sought to examine the identity narratives of therapeutic songwriting participants.

Design: Case-series analysis of the individual identity trajectories of eight individuals.

Setting: Subacute rehabilitation facility, Victoria, Australia.

Participants: Eight individuals with an SCI; 7 males and 1 female.

Intervention: Six-week therapeutic songwriting intervention facilitated by a music therapist to promote identity rehabilitation.

Outcome Measures: Identity, subjective well-being and distress, emotional state.

Results: Three participants demonstrated positive trajectories and a further three showed negative trajectories; remaining participants were ambiguous in their response. Injury severity differentiated those with positive trajectories from those with negative trajectories, with greater injury severity apparent for those showing negative trends. Self-concept also improved more in those with positive trajectories. Core demographic variables did not however meaningfully predict the direction of change in core identity or wellbeing indices.

Conclusion: Identity-focused songwriting holds promise as a means of promoting healthy identity reintegration. Further research on benefits for those with less severe spinal injuries is warranted.     

Genetic alterations in primary breast cancers and their metastases: Direct comparison using modified comparative genomic hybridization

Breast tumor development and progression are thought to be driven by an accumulation of genetic alterations, but little is known about the specific changes that occur during the metastatic process. We analyzed pairs of primary breast cancers and their matched lymph node metastases from 11 patients, pairs of primaries and distant metastases from three patients, and pairs of primaries, and local recurrences from two patients by using comparative genomic hybridization (CGH). Simultaneous hybridization analysis of primary versus matched lesion DNAs from 11 patients was also performed (modified CGH). This modified approach was useful not only for confirming CGH results but also for demonstrating quantitative differences between aberrations present at both sites. Frequent chromosomal changes present at both sites (>35% of 16 cases) were 1q, 8q, and 17q gains and 6q, 8p, 9q, 13q, 16q, 17p, and Xp losses. The total number of aberrations detected exclusively in the lymph nodes or distant metastases was higher than that in the primary tumors (2.5 vs. 0.7, P< 0.05). We found high-level amplifications in four metastases (two lymph nodes and two distant metastases), but none in any primary tumor. These findings suggest that progression from primary breast cancer to metastasis may be associated with the acquisition of further genetic changes. Although further investigations are required, it was of interest that 3 of 11 patients (27%) showed 18q loss solely in their lymph node metastases. Genes Chromosom.
