Preserving the health of ambulance personnel : some preliminary results from a study of pre-hospital emergency interventions

Little is known about the health of ambulance personnel, especially in Switzerland. This lack of knowledge is particularly striking in the specific field of occupational health. This study aims to identify and better understand protective and risk factors affecting the health of ambulance personnel. Both mental and physical health are considered. The approach used comprised two steps. The first step began in July 2008 and consisted in a qualitative study of real work activities performed by ambulance crews involved in pre-hospital emergency interventions. Researchers shadowed ambulance personnel for the duration of their entire work shift, in average for one week. The paper-pen technique was used to note dialogues, interactions, postural aspects, etc. When the situation allowed it, interventions were filmed. Some selected video sequences were used as a support for selfconfrontation interviews. Observations were performed by three researchers and took place in eleven services, for a total of 416 hours of observations (including 72 interventions + waiting time). Analysis, conducted by a multidisciplinary team (an ergonomist, an occupational therapist and a health psychologist), focused on individual and collective strategies used by ambulance personnel to protect their health. The second step, which is currently ongoing, aims to assess global health of ambulance personnel. A questionnaire is used to gather information about musculoskeletal complaints (Nordic questionnaire), mental health (GHQ-12), stress (Effort-Reward imbalance questionnaire), strategies implemented to cope with stress (Brief COPE), and working conditions. Specific items on strategies were developed based on observational data. It will be sent to all ambulance personnel employed in the French-speaking part of Switzerland. Preliminary analyses show different types of strategies used by ambulance personnel to preserve their health. These strategies involve postural aspects (e.g. use doorframe as a support to ease delicate manipulations), work environment adaptations (e.g. move furniture to avoid awkward postures), coping strategies (e.g. humor), as well as organisational (e.g. formal and informal debriefing) and collective (e.g. cooperation) mechanisms. In-depth analysis is still ongoing. However, patient safety and comfort, work environment and available resources appear to influence the choice of strategies ambulance personnel use. As far as possible, the strategies identified will be transformed into educational materials for professional ambulance personnel.

Efficacy of in-hospital multidimensional interventions of secondary prevention after acute coronary syndrome: a systematic review and meta-analysis

BACKGROUND: Secondary prevention programs for patients experiencing an acute coronary syndrome have been shown to be effective in the outpatient setting. The efficacy of in-hospital prevention interventions administered soon after acute cardiac events is unclear. We performed a systematic review and meta-analysis to determine whether in-hospital, patient-level interventions targeting multiple cardiovascular risk factors reduce all-cause mortality after an acute coronary syndrome. METHODS AND RESULTS: Using a prespecified search strategy, we included controlled clinical trials and before-after studies of secondary prevention interventions with at least a patient-level component (ie, education, counseling, or patient-specific order sets) initiated in hospital with outcomes of mortality, readmission, or reinfarction rates in acute coronary syndrome patients. We classified the interventions as patient-level interventions with or without associated healthcare provider-level interventions and/or system-level interventions. Twenty-six studies met our inclusion criteria. The summary estimate of 14 studies revealed a relative risk of all-cause mortality of 0.79 (95% CI, 0.69 to 0.92; n=37,585) at 1 year. However, the apparent benefit depended on study design and level of intervention. The before-after studies suggested reduced mortality (relative risk [RR], 0.77; 95% CI, 0.66 to 0.90; n=3680 deaths), whereas the RR was 0.96 (95% CI, 0.64 to 1.44; n=99 deaths) among the controlled clinical trials. Only interventions including a provider- or system-level intervention suggested reduced mortality compared with patient-level-only interventions. CONCLUSIONS: The evidence for in-hospital, patient-level interventions for secondary prevention is promising but not definitive because only before-after studies suggest a significant reduction in mortality. Future research should formally test which components of interventions provide the greatest benefit.

Décès après interventions chirurgicales : investigation par l'angio-TDM post-mortem.

Objectifs: Des décès suite à une intervention chirurgicale sont autopsiés dans le but de déterminer le cause de la mort et investiguer une éventuelle erreur médicale . Le butde l'étude est d'évaluer l'utilité de l'angio-TDM post mortem pour ce type d'investigations médico-légales délicates. Matériels et méthodes: 145 cas médico-légaux ont été investigués. De ce collectif, huit cas impliquaient une intervention chirurgicale pour laquelle le décès pouvait être éventuellementimputé. Les résultats des examens radiologiques ont été comparés avec ceux obtenus par l'autopsie conventionnelle. Résultats: La cause du décès était soit un choc hémorragique ou septique, soit la combinaison d'une hémorragie et d'une aspiration de sang. Le diagnostic a pu être posélors de l'autopsie conventionnelle de même que lors de l'examen radiologique. Cependant, l'examen par angio-TDM a permis de détecter la source exacte deshémorragies dans cinq des six cas, alors que l'autopsie n'a permis de localiser le site hémorragique approximativement que dans trois cas . Conclusion: L'angio-TDM post-mortem est recommandée dans les cas de décès post-interventionnels. Elle permet de documenter les constatations et de réexaminer les casultérieurement. De plus, la source exacte des hémorragies peut être localisée ce qui est d'une grande importance dans ce genre de cas.

Psychodynamic interventions in cancer care II: a qualitative analysis of the therapists' reports.

BACKGROUND: To investigate the focus of psychodynamic-oriented interventions in cancer patients by means of a qualitative analysis of the therapists' reports. METHODS: One hundred thirty-five reports collected within a controlled psychotherapy trial were analyzed; the themes addressed during the intervention were classified in categories reflecting the focus of the intervention and correlated with sociodemographic and medical data and type of intervention. RESULTS: Twenty main themes were identified and classified in two categories: category 1 corresponded to interventions based on expression and support, and category 2 to interventions based on introspection, with subcategory 2.1 focusing on the patient's psychological functioning and subcategory 2.2 focusing on his way to engage and communicate in relationships. While the most frequently addressed theme was related to the diagnosis of cancer (N = 102/576; 22.6%), the majority of themes were related to other concerns (N = 446/576; 77.4%). Half of the interventions (50.4%) were classified in category 1, 27.4% in category 2.1, and 9.6% in category 2.2. Patients of category 1 entered less often brief psychotherapy (step 2 of the intervention) and more frequently suffered from advances disease. CONCLUSIONS: A wide variety of themes are addressed in psychodynamic interventions in the oncology setting, illustrating that cancer is not the only focus of therapy. Other themes reflect different psychological difficulties triggered by the disease. This study illustrates that cancer patients have different needs, which surpass the event of the disease. Early clarification and comprehension of the demand may therefore be beneficial to adjust the therapeutic approach. Copyright © 2013 John Wiley & Sons, Ltd.

Role of glutathione deficit in the disconnectivity syndrome in schizophrenia: from pathogenetic mechanisms to therapeutic interventions

In the cerebrospinal fluid of 26 drug-naive schizophrenics (DSM-III- R), we observed that the level of glutathione ([GSH]) and of its metabolite γ-Glu-Gln was decreased by 27% and 16% respectively. Using a new in-vivo method based on magnetic resonance spec- troscopy, [GSH] was measured in the medial prefrontal cortex of 18 schizophrenics and found to be 52 % lower than in controls (n = 20). This is consistent with the recently observed decreased mRNA levels in fibroblasts of patients (n=32) of the two GSH synthesizing en- zymes (glutathione synthetase (GSS), and glutamate-cysteine ligase M (GCLM) the modulatory subunit of glutamate-cysteine ligase). Moreover, the level of GCLM expression in fibroblasts correlates neg- atively with the psychopathology (positive, general and some nega- tive symptoms). Thus, the observed difference in gene expression is not only the cause of low brain [GSH], but is also related to the sever- ity of symptoms, suggesting that fibroblasts are adequate surrogate for brain tissue. A hypothesis was proposed, based on a central role of GSH in the pathophysiology of schizophrenia. GSH is an important endogenous redox regulator and neuroactive substance. GSH is pro- tecting cells from damage by reactive oxygen species generated, among others, by the metabolism of dopamine. A GSH deficit-in- duced oxidative stress would lead to lipid peroxidation and micro-le- sions in the surrounding of catecholamine terminals, affecting the synaptic contacts on dendritic spines of cortical neurones, where ex- citatory glutamatergic terminals converge with dopaminergic ones. This would lead to spines degeneration and abnormal nervous con- nections or structural disconnectivity, possibly responsible for posi- tive, perceptive and cognitive symptoms of schizophrenia. In addi- tion, a GSH deficit could also lead to a functional disconnectivity by depressing NMDA neurotransmission, in analogy to phencyclidine effects. Present experimental biochemical, cell biological and behav- ioral data are consistent with the proposed mechanism: decreasing pharmacologically [GSH] in experimental models, with or without blocking DA uptake (GBR12909), induces morphological and behav- ioral changes similar to those observed in patients. Dendritic spines: (a) In neuronal cultures, low [GSH] and DA induce decreased density of neural processes; (b) In developing rats (p5-p16), [GSH] deficit and GBR induce a decrease in normal spines in prefrontal pyramids and in GABA-parvalbumine but not of -calretinine immunoreactivity in anterior cingulate. NMDA-dependant synaptic plasticity: GSH deple- I/13 tion in hippocampal slices impairs long-term potentiation. Develop- ing rats with low [GSH] and GBR have deficit in olfactory integration and in object recognition which appears earlier in males than fe- males, in analogy to the delay of the psychosis onset between man and woman. In summary, a deficit of GSH and/or GSH-related enzymes during early development could constitute a major vulnerability fac- tor in schizophrenia.
