RESUMEN

Objectives: COVID-19 pandemic and its consequences have put into great difficulty health professionals, and the general population, fostering the emergence of various psychological and psychiatric disorders. Medical and psychological emergency units' mission is the medical and psychological emergency care of people impacted during a traumatic event. Given their expertise in crisis management, they set up an important medical and psychological support system adapted to the health crisis' characteristics. The unusual modalities of intervention, the specific clinic that these professionals faced in this context of great tension may have unsettled workers and generate a psychological impact. This study aims to assess the existence of such repercussions among medical and psychological emergency unit professionals involved in this new system. Method: In all, 313 medical and psychological emergency unit professionals agreed to participate at the online survey. They filled surveys and visual analog scales assessing the difficulties encountered in the system, as well as their level of satisfaction, post-traumatic stress, burnout, level of anxiety and depression and coping strategies put in place. Results: Results show few significant emotional difficulties. However higher scores are found among women, among professionals who felt a negative impact on their personal lives, as well as for those who thought they had been infected with COVID-19. The establishment of coping strategies such as active coping, planning, expressing feelings, positive reinterpretation and acceptance helped to decrease the level of emotional complexities and brought more compassionate satisfaction. We note that participants with more medical and psychological emergency unit experience tend to show less emotional hardship and more compassionate satisfaction. It appears that older as well as younger professionals have lower burnout scores, as do workers who conducted more interviews for the same person. Likewise, participants who were satisfied of the system organization and of the support - a majority in this study - report less emotional challenges and more compassionate satisfaction. Conclusion: Psychological impact in this new system among medical and psychological emergency unit professionals is overall low. It appears that some coping strategies, perceived usefulness, satisfaction with the organization and the received support are associated with a lower level of emotional difficulties. A supportive framework and an operative organization of the medical and psychological emergency unit system in times of crisis has a protective effect on the participants.

RESUMEN

INTRODUCTION: The early postattempt period is considered to be one of the most at-risk time windows for suicide reattempt or completion. Among the postcrisis prevention programmes developed to compensate for this risk, brief contact interventions (BCIs) have been proven to be efficient but not equally for each subpopulation of attempters. VigilanS is a region-wide programme that relies on an algorithmic system to tailor surveillance and BCI provisions to individuals discharged from the hospital after a suicide attempt. AIM: VigilanS' main objective is to reduce suicide and suicide reattempt rates both at the individual level (patients included in VigilanS) and at the populational level (inhabitants of the Nord-Pas-de-Calais region). METHODS AND ANALYSIS: At discharge, every attempter coming from a participating centre is given a crisis card with an emergency number to contact in case of distress. Patients are then systematically recontacted 6 months later. An additional 10-day call is also given if the index suicide attempt is not the first one. Depending on the clinical evaluation during the phone call, the call team may carry out proportionated crisis interventions. Personalised postcards are sent whenever patients are unreachable by phone or in distress. On the populational level, mean suicide and suicide attempt rates in Nord-Pas-de-Calais will be compared before and after the implementation of the programme. Here/there cross-sectional comparisons with a control region will test the spatial specificity of the observed fluctuations, while time-series analyses will be performed to corroborate the temporal plausibility of imputing these fluctuations to the implementation of the programme. On the individual level, patients entered in VigilanS will be prospectively compared with a matched control cohort by means of survival analyses (survival curve comparisons and Cox models). DISCUSSION: VigilanS interventional components fall under the ordinary law care regime, and the individuals' general rights as patients apply with no addendums or restrictions for their participation in the programme. The research section received authorisation from the Ethical Committee of Lille Nord-Ouest under the caption 'Study aimed at evaluating routine care' and is registered in 'Clinical Trials'. The French Ministry of Health plans to extend the experimentation to other regions and probe the relevance of this type of 'bottom-up' territorial prevention policy at the national level. TRIAL REGISTRATION NUMBER: NCT03134885.

RESUMEN

BACKGROUND: There is growing evidence in the literature that brief contact interventions (BCIs) might be reliable suicide prevention strategies. OBJECTIVE: To assess the effectiveness of a decision-making algorithm for suicide prevention (ALGOS) combining existing BCIs in reducing suicide reattempts in patients discharged after a suicide attempt. METHODS: A randomized, multicenter, controlled, parallel trial was conducted in 23 hospitals. The study was conducted from January 26, 2010, to February 28, 2013. People who had made a suicide attempt were randomly assigned to either the intervention group (ALGOS) or the control group. The primary outcome was the rate of participants who reattempted suicide (fatal or not) within the 6-month study period. RESULTS: 1,040 patients were recruited. After 6 months, 58 participants in the intervention group (12.8%) reattempted suicide compared with 77 (17.2%) in the control group. The difference between groups (4.4%; 95% CI, -0.7% to 9.0%) was not significant (complete-case analysis, P = .059). CONCLUSIONS: These results may help researchers better integrate BCIs into routine health care and provide new insights concerning personalized suicide prevention strategies. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01123174.

RESUMEN

OBJECTIVE: Survival rate of cardiac arrest due to hanging (H-CA) victims is low. Hence, this leads to the question of the utility of resuscitation in these patients. The objective was to investigate whether there are predictive criteria for survival with a good neurological outcome or predictive criteria for non-survival or survival with a poor neurological outcome enabling us to define the termination of resuscitation rules in these patients. METHODS: Between July 1, 2011 and January 1, 2016, we included 1,689 out-of-hospital cardiac arrests due to hanging. We compared the characteristics of survivors with a good neurological outcome at day 30 with the others. RESULTS: The study population was mainly composed of males with a median age of 48 [37-60]. The overall survival was 2.1%, among which 48.6% had a good neurological outcome. Survivors benefited more often from immediate basic life support than the rest of the subjects, which was corroborated by the shorter no-flow durations. We did not record any difference in terms of advanced cardiac life support initiation frequency and technique between survivors with a good neurological outcome and the rest. Nevertheless, ACLS duration was longer in survivors with a good neurological outcome than in others. CONCLUSIONS: Basic life support (BLS) was the decisive criterion for 15/17 survivors. However, a detailed analysis showed 2 survivors presenting no BLS before the arrival of mobile medical teams and non-shockable rhythms who survived at day 30 with a good neurological outcome. These results lead us to consider that mobile medical team intervention and ACLS attempt are not futile, and the benefit justifies the cost. Thus, we cannot define any rule for the termination of resuscitation.

RESUMEN

Important discrepancies exist between physicians in deciding when to perform involuntary hospitalization measures (IHMs). The factors underlying these differences are poorly known.We conducted a two-year single-center retrospective study in France on patients who were referred to the emergency department (ED) with an IHM certificate written by a private-practice General Practitioner (GP). For each consultation, the official IHM motive was categorized into four groups: Suicide; Psychosis, Mania, or Melancholia (PMM); Agitation; and Other. The alcohol status of the patient was also noted. The factors underlying the ED psychiatrists' confirmation of the use of IHMs were determined using a logistic regression model. One hundred eighty-nine cases were found (165 patients; 44.2 ± 16 years, 41.3% women). The ED psychiatrists confirmed the use of IHMs in 123 instances (65.1% agreement rate). Multivariate analyses found that IHM disagreement was significantly associated with patient alcohol status and the reason for referral. Specifically, there was an increased risk of IHM disagreement when the patient had an alcohol-positive status (OR = 15.80; 95% CI [6.45-38.67]; p < 0.0001) and when the motive for IHM was "agitation" compared with "suicide" (OR = 11.44; 95% CI[3.38-38.78]; p < 0.0001). These findings reflect significant disparities between GPs and ED psychiatrists regarding the decision to proceed to an IHM.

RESUMEN

BACKGROUND: The mortality of people suffering from psychiatric illnesses is far higher than that of the general population, all categories of diagnosis combined; mortality statistics can be used as an index of quality of care. The aim of this study was to assess the all-cause mortality in psychiatric patients covering all diagnostic groups. METHODS: The living or deceased status of 4,417 patients of majority age hospitalised in a public mental health establishment between 2004 and 2007 were requested from French National Institute for Statistics and Economic Studies on 1st January 2011. The cause of death of those people who had died was obtained from French National Institute for Health and Medical Research and comparative standardized mortality ratios (SMR) were established from the population in a region of northern France of the same age in 2006. RESULTS: The study population was made up of 54% men and 46% women, median age 41 and 45 years old, respectively. Four hundred and seventy-three people died during the period studied. The SMR were 421 for men (95% CI 378-470) and 330 for women (95% CI 281-388). The highest SMRs were found in patients aged 35-54, with a 20-time higher mortality risk than the general population of the same age. CONCLUSION: Our study confirms the considerably higher mortality in psychiatric patients than in general population, particularly in mean age and mostly due to an unnatural cause.

RESUMEN

BACKGROUND: Road Traffic Accidents (RTA) are most probably the leading cause of post traumatic stress disorder (PTSD) in developed countries. The autonomic nervous system (ANS) disturbances, due to psychological trauma, are part of the pathophysiology of PTSD. The aim of the present study was to determine whether early heart rate variability (HRV) measurement, a biomarker of the ANS function, could act as a predictor of PTSD development after a RTA. METHODS: We prospectively investigated 35 survivors of RTA with both physical injury and psychological trauma. HRV data were obtained from 24-h Holter ECG monitoring, which was performed on the second day after the accident. Time domain analysis was applied to the inter-beat (RR) interval time series to calculate the various parameters of HRV. PTSD status was assessed 2 and 6 months after RTA. RESULTS: There was a global diminution of HRV measurements in the PTSD group at both 2 and 6 months. The variability index was the best predictor of PTSD with the area under the receiveroperating curve for discriminating PTSD at 6 months at 0.92 (95% CI: 0.785; 1.046). A cut-off at 2.19% yielded a sensitivity of 85.7% and a specificity of 81.8% for PTSD. Positive and negative predictive values were respectively 75% and 90%. However, initial heart rate (HR) data were relevant at 2 months but not at 6 months. CONCLUSION: RTA survivors exhibiting lower parasympathetic modulation of HR, indexed by temporal analysis of HRV, are more susceptible to developing PTSD as a short and long-term outcome.

RESUMEN

A subject surviving a suicide attempt (SA) belongs in fact to a group at risk for suicide (40% of lifetime repetition including 20 to 25% over the 12 months following the initial gesture). To prevent the risk of suicide in general is thus effective on the prevention of the repetition. It initially seems important to treat a somatic or psychiatric pathology having taken part in the initial suicidal context: treating a mood depression disorder, prescribing a mood stabilizer to a bipolar patient, managing the global treatment of a borderline personality disorder, etc. Some strategies have been proposed with a specific aim to reduce this rate of suicidal repetition. Certain devices very interventionists appear expensive and difficult to generalize (at home interventions, intensive short psychotherapies carried out starting from the Emergency Rooms...). In a parallel way, "connectedness" devices, which are careful not to invade the suicide attempter life, which does not aim to replace a treatment, but try to propose effective recourse in case of crisis, tend to currently develop on the whole territory.

RESUMEN

BACKGROUND: Suicide attempts (SA) constitute a serious clinical problem. People who attempt suicide are at high risk of further repetition. However, no interventions have been shown to be effective in reducing repetition in this group of patients. METHODS/DESIGN: Multicentre randomized controlled trial. We examine the effectiveness of "ALGOS algorithm": an intervention based in a decisional tree of contact type which aims at reducing the incidence of repeated suicide attempt during 6 months. This algorithm of case management comprises the two strategies of intervention that showed a significant reduction in the number of SA repeaters: systematic telephone contact (ineffective in first-attempters) and "Crisis card" (effective only in first-attempters). Participants who are lost from contact and those refusing healthcare, can then benefit from "short letters" or "postcards". DISCUSSION: ALGOS algorithm is easily reproducible and inexpensive intervention that will supply the guidelines for assessment and management of a population sometimes in difficulties with healthcare compliance. Furthermore, it will target some of these subgroups of patients by providing specific interventions for optimizing the benefits of case management strategy.

RESUMEN

Beside the major events like catastrophe, the psychological consequences of a traumatic confrontation can represent for the subject multiple clinical forms, even in events likely to be regarded as usual. After immediate stress often spectacular and sometimes maladjusted, subject is able in the short or the long term to develop a whole of symptoms often invalidating. Post traumatic stress disorder (PTSD) represents a specific condition known to be frequent and disabling as well in general population as in exposed populations. Nevertheless, PTSD is an anxious disorder which etiology, development, clinical recognition and dimensioning are well controlled and for which the strategies of care are relatively consensual.

RESUMEN

Early assessment is essential for subjects exposed to a potentially traumatic event. Symptoms of peritraumatic distress are often predictive of later posttraumatic stress disorders and should be treated promptly. Posttraumatic stress disorders should be treated rapidly, before they become chronic. It is also necessary to consider the frequent comorbidities: psychosomatic features, addictive disorders, and especially posttraumatic depression. Attempted suicide is 15 times more common in people with psychological trauma than in the general population. Posttraumatic stress disorders that have lasted several years become resistant to treatment (pharmacological and psychotherapeutic).

RESUMEN

OBJECTIVE: Gamma-aminobutyric acid (GABA) exerts a prominent effect on central adrenergic stress responses in times of high stress and has been associated with acute posttraumatic stress disorder (PTSD). The authors examined the association between low posttrauma plasma GABA levels and long-term PTSD. METHOD: Plasma GABA levels were measured in 78 victims of road traffic accidents who met criteria for trauma exposure on arrival at a trauma department and were admitted for at least 3 days. Patients were assessed for PTSD and major depressive disorder at 6-week and 1-year follow-ups. RESULTS: At 6 weeks and at 1 year, mean posttrauma GABA levels were significantly lower among subjects who met all or nearly all criteria for PTSD than among those who did not. Among patients who met all or nearly all criteria for PTSD at 6 weeks, 75% of those with posttrauma GABA levels above 0.20 mmol/ml no longer met criteria at 1 year. By contrast, among patients whose GABA levels were below 0.20 mmol/ml, 80% met all or nearly all criteria for PTSD at 1 year. Two-thirds of patients who met all or nearly all criteria for PTSD at 1 year also met criteria for major depressive disorder. CONCLUSIONS: A plasma GABA level above 0.20 mmol/ml may protect against chronic PTSD and may represent a marker of recovery from trauma.

RESUMEN

OBJECTIVE: To determine the effects over one year of contacting patients by telephone one month or three months after being discharged from an emergency department for deliberate self poisoning compared with usual treatment. DESIGN: Multicentre, randomised controlled trial. SETTING: 13 emergency departments in the north of France. PARTICIPANTS: 605 people discharged from an emergency department after attempted suicide by deliberate self poisoning. INTERVENTION: The intervention consisted of contacting patients by telephone at one month or three months after discharge from an emergency department for attempted suicide to evaluate the success of recommended treatment or to adjust treatment. Control patients received treatment as usual, in most cases referral back to their general practitioner. MAIN OUTCOME MEASURES: The primary outcome measures were proportion of participants who reattempted suicide, number of deaths by suicide, and losses to follow-up at 13 months' follow-up. Secondary outcome measures were types and number of contacts with health care. RESULTS: On an intention to treat basis, the three groups did not differ significantly for further suicide attempts, deaths by suicide, or losses to follow-up: contact at one month (intervention 23% (34/147) v controls 30% (93/312), difference 7%, 95% confidence interval - 2% to 15%), three months (25% (36/146) v 30%, difference 5%, - 4% to 14%). Participants contacted at one month were less likely at follow-up to report having reattempted suicide (12% v 22% in control group, difference 10%, 2% to 18%). CONCLUSION: Contacting people by telephone one month after being discharged from an emergency department for deliberate self poisoning may help reduce the number of reattempted suicides over one year.

RESUMEN

Diagnosis of post traumatic stress disorder (PTSD) requires a past history of psychic traumatism and characteristic psychotraumatic symptoms like re-experiencing of the traumatic event, avoidance of stimuli associated with the traumatic event and increased arousal. In the elderly, PTSD prevalence rate is about 0.9% after 60 years of age. Clinical features are almost identical to those observed in younger patients. However there are various types of PTSD: PTSD de novo, occurring after exposure to extreme trauma in old age; chronic PTSD when symptoms persist since the time of the trauma; delayed-onset PTSD when patients exhibit signs of the disorder decades after the trauma; complex PTSD, generated by exposure to repeated traumatisms in early development, who could be linked up to changes in personality in older exposed to repeated traumatisms. Pharmacological and psychotherapic interventions used in younger populations can be applied for treatment to older adults, when taking into account the pharmacodynamic and psychic changes associated with aging.

RESUMEN

Post-traumatic stress disorder (PTSD) affects a vulnerable sub-population of individuals exposed to a traumatic event. This psychopathology induces long-lasting hypothalamo-pituitary-adrenal (HPA) axis hypoactivity, hyperarousal and avoidance of trauma-like situation. PTSD also manifests a high co-morbidity with anxiety disorders. The aim of the present study was to characterise long-term biobehavioural alterations in female rats in an animal model of PTSD consisting in an intense footshock (2 mA, 10s) followed by three weekly situational reminders. This procedure induced several long-term alterations: increased anxiety behaviour, reduced time spent in an 'aversive-like' context, altered social behaviour and blunted corticosterone response to stress. These results demonstrate that exposure to an intense footshock associated with repeated situational reminders elicited long-term disturbances which lasted more than 1 month after the footshock administration. Our findings suggest that this paradigm could provide a useful animal model of PTSD.

RESUMEN

BACKGROUND: Gamma amino-butyric acid (GABA) regulates the intensity and the duration of the central hyperadrenergic response in times of high stress and has been negatively associated with anxiety, depression, and sleep problems. We hypothesized that individuals with low plasma GABA levels may be more prone to develop posttraumatic stress disorder (PTSD) in the aftermath of trauma exposure. METHODS: To test this hypothesis, we measured plasma GABA levels in a population of 108 road traffic accident victims on arrival at a traumatology department and assessed them for PTSD 6 weeks later. RESULTS: The mean GABA level (nmol/mL) in the PTSD group (n = 55; M =.20; SD =.08) was significantly lower compared with members of the trauma-exposed group who did not develop PTSD [n = 17; M =.30; SD =.09), t(70) = 3.94, p =.0002]. CONCLUSIONS: Provided that GABA levels in the brain are genetically predetermined, our results would suggest that individuals with low plasma GABA levels are premorbidly more vulnerable to stress-related disorders such as acute PTSD. If replicated, plasma GABA levels measured in the aftermath of trauma exposure might help to identify individuals at high risk for developing PTSD.

RESUMEN

BACKGROUND: This study investigated the efficacy of propranolol prescribed shortly after trauma exposure in the prevention of posttraumatic stress disorder (PTSD) symptoms and diagnosis. METHODS: Eleven patients received 40 mg of propranolol 3 times daily for 7 days, followed by a taper period of 8-12 days. They were compared with eight patients who refused propranolol but agreed to participate in the study. Though nonrandomized, the two groups did not differ on demographics, exposure characteristics, physical injury severity, or peritraumatic emotional responses. RESULTS: Posttraumatic stress disorder rates were higher in the group who refused propranolol (3/8) compared with those who received the medication (1/11), as were the levels of PTSD symptoms (U = 85, p =.037). CONCLUSIONS: Our results are consistent with earlier findings and suggest that propranolol may be useful for mitigating PTSD symptoms or perhaps even preventing the development of PTSD.
