[Impact of the suicidal crisis intervention training program on the confidence and skills of hospital professionals in the Hauts-de-France region]

INTRODUCTION

Suicide is a major public health issue given its huge human and economic consequences. Symptoms prior to suicide are often not specific. Nevertheless, the majority of suicidal people express suicidal thoughts, and nearly one in two meet a health professional in the period preceding the act. Being able to recognize the warnings and intervene during the suicidal crisis, defined as a mental crisis where the major risk is suicide, is to seize the opportunity to postpone the suicidal plan and to gain time to implement in place lasting strategies to combat suffering. Thus, the training for suicidal crisis intervention is a major axis of the suicide prevention strategy. Recently, crisis intervention training programs have been updated with knowledge accumulated since the early 2000's. In France, one of the countries most concerned by suicide, the Hauts-de-France region is one of the most impacted. In this context, the Regional Health Agency of Hauts-de-France included in its Regional Health Program of 2018-2023 the training of healthcare workers who work with high suicidal risk patients. The suicidal crisis intervention training program (SCIT) has been introduced to hospital staffs in Hauts-de-France. The purpose of this study was to evaluate this program.

METHODS

Eight training sessions with 15 to 21 participants were carried out from 2019 November to 2021 January in the Hauts-de-France region. Participants were volunteer healthcare professionals in direct contact with suicidal crisis patients. The training included three modules. The first one concerned the suicidal crisis intervention training: definition of the suicidal crisis, typology of the crisis, vulnerability development, crisis evaluation and crisis intervention practice. The second concerned the evaluation with the RED scale (Risk-Emergency-Danger) and the adequate patient orientation to a psychiatric unit. The third was dedicated to the Gatekeeper training with the constitution of a Gatekeeper network to enhance the capacity to detect suicidal risk and to orient the concerned person towards an adequate evaluation or care organization. We evaluated the first two levels of the Kirkpatrick's model: level 1) the participant's satisfaction (rated out of 10), and level 2) the degree of confidence in their professional abilities (rated out of 10) and their skills in responding to a person in a suicidal crisis (using the SIRI-2-VF - French version of the Suicide Intervention Response Inventory-2). The participants were interviewed before (T0), just after (T1) and at one month of training (T2).

RESULTS

Among the 141 health professionals who followed the training, 139 answered the questionnaire at least one time (13 psychologists, 22 doctors, 97 nurses and 7 head nurses). The participation rates were 99.3 % at T0, 96.4 % at T1 and 46.0 % at T2. Most of the participants were nurses (69.8 %), and 33.1 % of the respondents declared they had already followed a suicidal crisis training. The satisfaction with the training was evaluated at 8.6 (± 1.3) out of 10. There was no significant difference among the professions, neither between those having already received or not a previous training. The self-perceived capacity to manage a suicidal crisis was rate 6.8 (± 1.8) out of 10 at T0. There was a significant increase just after the training (8.1±1.2 vs 6,8±1,8, p<0,001) which persisted at 1 month (8.1±1.1 vs 6.8±1.8, P<0.001). The score at the SIRI-2-VF was 15.0 (± 4.2) out of 30 at T0. There was a significant increase just after the training (17.5±3.5 vs 15.0±4.2, P<0.001), which persisted at 1 month (17.0±4.0 vs 15.0±4.2, P<0.001).

DISCUSSION

This is the first evaluation of the suicidal crisis intervention training program. This program increased and homogenized the competency of the participants to manage suicidal ideation and behaviors. Those who followed a previous training maintained higher scores than the others, which shows the importance of repeated training to maintain a satisfying level of knowledge over the long term. One of the strengths of this training is the use of roleplay which enhances the learning and abilities to interact with people at suicidal risk. It seems important to integrate a suicidal crisis intervention training in the cursus of health students to avoid suicide and the dramatic consequences for the entourage and the health professionals who are confronted with it.

CONCLUSION

The SCIT program showed encouraging results in terms of confidence and capacity of the healthcare professionals to intervene in suicidal crisis.

Effectiveness of a French Program to Prevent Suicide Reattempt (VigilanS)

AIM

Brief contact interventions (such as letters, green cards, telephone calls or postcards) for reducing suicide reattempt (SR) and suicide have been evaluated since the 1980s, but results have been inconsistent. VigilanS is one of these programs that has benefited patients hospitalized for suicide attempt (SA) after discharge in 2 departments of northern France since 2015. The purpose of this study is to demonstrate its effectiveness in reducing SR.

METHODS

Patients exposed to VigilanS in 2016 were recruited from the medical administrative database of the program, and the nonexposed patients from a database of the medico-surgical ward outside the scope of the program. First, a Cox model was used to compare the probability of SR during the 12-month follow-up period between the 2 groups. Second, a propensity score using the variables sex, age, source, SA history and SA method was used to match the VigilanS-exposed and the nonexposed patients. A Cox model propensity score adjusted analysis was reiterated on the matched data.

RESULTS

The exposed and nonexposed groups included 3,068 and 3,694 individuals, respectively. In the bivariate analyses, the cumulative probability of SR at 12 months was significantly lower in the exposed group (6.0%, 95% confidence interval (CI): 5.5-6.5%) than in the nonexposed group (16.8%, 95% CI: 15.9-17.7%; p < 0.001). In the Cox model, the hazard ratio of SR was 0.38 in the exposed patients (95% CI: 0.36-0.40, p < 0.001). After matching, the cumulative probability of SR at 12 months was 5.2% in exposed versus 22.2% in nonexposed patients (p < 0.001). In the propensity score-adjusted Cox model, the hazard ratio of SR in the exposed patients was 0.19 (95% CI: 0.14-0.24, p < 0.001).

CONCLUSION

The results suggest the effectiveness of this real-life program for reducing SR. However, VigilanS only benefits a portion of the patients hospitalized for SA and therefore could be extended.

[Risk of incarceration of persons undergoing psychiatric care. A retrospective longitudinal study on the French department of Oise using information from a psychiatric hospital discharge database]

INTRODUCTION

Compared to the general population, persons with mental disorders are overrepresented in prison. In a study carried out in Picardy (northern France) in 2017, a quarter of those entering prison had had contact with a psychiatric service prior to their incarceration. Since to our knowledge no work on this subject has been published in France, we conducted a retrospective study, the main objective of which was to propose an estimate measure of incarceration likelihood in people with mental disorders.

METHODS

Using data from a psychiatric hospital discharge database (Recueil d'informations médicalisé en psychiatrie, RimP), we searched for patients aged 18 and older who had received psychiatric care (except for those who were incarcerated at baseline) at the Oise psychiatric hospital in 2015-2016 and identified those who had also been registered by the psychiatric care tool (DSP) in liaison with the same hospital. As a marker of incarceration, registration was the event to be investigated. Survival analyses (Kaplan-Meier), first simple and then stratified by age, gender, past history, main diagnosis and intensity of care outside of prison were carried out to calculate likelihood of incarceration. A multivariate Cox model was used in order to identify the factors associated with incarceration.

RESULTS

Among the 25,029 patients monitored in the Oise psychiatric hospital in 2015-2016, 126 had experienced incarceration during the 12 months following their inclusion in the study, i.e. an incarceration probability of 0.45% (95 % confidence interval: 0.37-0.55%). The incarcerated patients were younger (36.6 years in average versus 44.7-Pt-test<0.0001), more often male (96.8% versus 43.7% - P<0.0001), and had a more frequent history of detention (11.1% versus 0.6% - P <0.0001) and psychiatric care (20.6% versus 10.1% - P<0.0001) than the general population. The probability of incarceration at 12 months for the population followed in the psychiatry unit was 3.2 times higher than the detention rate of the general population in Oise over the same period.

CONCLUSION

Our study confirms the pronouncedly high incarceration rate of people with mental disorders. Scheduled to begin in 2020, coding in the RimP of a single nationwide patient identifier for all the procedures and stays described will allow the generalized measurement by means of the proposed indicator throughout France.

Management of work-related common mental disorders in general practice: a cross-sectional study

BACKGROUND

General practitioners (GPs) often manage individuals with work-related common mental disorders (CMD: depressive disorders, anxiety and alcohol abuse). However, little is known about the ways in which they proceed. The aim of this study is to analyze GPs' management and patterns of referral to other health professionals of patients with work-related CMD and associated factors.

METHOD

We used data from a cross-sectional study of 2027 working patients of 121 GPs in the Nord - Pas-de-Calais region in France (April - August 2014). Statistical analyses focused on patients with work-related CMD detected by the GP and examined the ways in which GPs managed these patients' symptoms. Associations between patient, work, GP and contextual characteristics and GPs' management were explored using modified Poisson regression models with robust variance.

RESULTS

Among the 533 patients with work-related CMD in the study, GPs provided psychosocial support to 88.0%, prescribed psychotropic treatment to 82.4% and put 50.7% on sick leave. Referral rates to mental health specialists and occupational physicians were respectively 39.8 and 26.1%. Several factors including patients' characteristics (occupational and sociodemographic), GPs' characteristics and environmental data were associated with the type of management used by the GP.

CONCLUSION

Our study emphasizes the major and often lonesome role of the GP in the management of patients with work-related CMDs. Better knowledge of the way GPs manage those patients could help GPs in their practice, improve patients care and be a starting point to implement a more collaborative care approach.

Santé mentale et conduites suicidaires des médecins généralistes

Étude épidémiologique, quantitative, centrée sur une population de 2052 médecins généralistes libéraux du Nord–Pas-de-Calais. Avec 287 réponses exploitables, le taux de participation est de 14 %. Un médecin sur 4 (n = 75) déclare avoir déjà présenté des idées suicidaires au cours de sa carrière, 22 déclarent avoir déjà imaginé un scénario suicidaire précis et une personne déclare une tentative de suicide. Le sur-risque de présenter des idées suicidaires est de 3,5 (IC 95 % 1,3–9,5) p = 0,055 chez les médecins âgés de plus de 60 ans et de 2,6 (IC 95 % 1,2–5,6) p = 0,065 chez les médecins stressés par leurs cotisations. Les médecins stressés par la gestion de leur cabinet présentent 12,9 (IC 95 % 3–54,4) fois plus de risque d’avoir des idées suicidaires, p = 0,003 et sont 15,8 (IC 95 % 4,2–59,2) fois plus à risque de faire des plans pour se suicider, p = 0,001. Le sur-risque de burn out ressenti et de dépression est de 12,7 (IC 95 % 2,6–61,3) p = 0,0016 chez les médecins victimes de litiges personnels et de 2,4 (IC 95 % 1,1–5,2) p = 0,0268 en cas de solitude professionnelle ressentie. Le statut de Maître de Stage des Universités et les enfants à charge semblent protéger de la dépression et du désespoir. Une prévalence anormalement élevée des idées suicidaires a bien été mise en évidence. L’âge supérieur à 60 ans, le stress des cotisations et le stress lié à la gestion du cabinet semblent être des marqueurs de risque d’idées suicidaires. Les litiges personnels et la solitude professionnelle ressentie semblent être des marqueurs de risque de burn out et de dépression. Pas de conclusion sur les tentatives de suicide par respect de l’anonymat de l’unique répondant.

[Changes in blood pressure after introduction of an antidepressant in a public institution of mental health]

INTRODUCTION

Primary prescribing of antidepressants is common in general practice. The relationship between antidepressant introduction and blood pressure (BP) changes is not well established in the literature. The purpose of our study was to examine the short-term course of AHR with and without the introduction of an antidepressant into a public institution of mental health (EPSM).

MATERIALS AND METHODS

An exposed/non-exposed single-centre analytical epidemiological study on a retrospective cohort, with a collection of data on stays between 2013 and 2015 at the EPSM in Armentières. The stays were divided into two groups: antidepressant treatment (introduced during the stay) and control (without antidepressant). BP measurements were taken over a 30-day period per stay. To assess the evolution of AHR across groups, we used a nested mixed linear regression model with multivariate adjustment.

RESULTS

Out of 1241 stays analysed, 124 were in the treated group and 1117 in the control group. The average age was 44.6±14.7 years. The two groups were comparable on most of the variables analyzed. The change in systolic BP was associated with systolic BP values at baseline, history of hypertension, presence of an antihypertensive drug and BMI; the change in diastolic BP was associated with diastolic BP values at baseline, presence of an antihypertensive drug, BMI and history of bipolar disorder. We find no significant difference in the evolution of BP over time between the treated group and the control group over the 30 days of measurement per stay, after adjustment (evolution coefficient of +0.12mmHg systolic BP and -0.1mmHg diastolic BP, P=0.45 and 0.38 respectively).

CONCLUSION

These results are reassuring on the early development of BP after the introduction of antidepressants. They should not overlook the frequent effects of depression and antidepressants on cardiovascular risk (decreased physical activity, dyslipidemia, weight gain, etc.).

[Changes in the number of suicide attempts in the NPC region since the start of VigilanS: First estimates]

BACKGROUND

The implementation of a surveillance program after a suicide attempt (SA) is a very innovative step in the evolution of our system of care. It was interesting to know if we observe a decline in suicide attempts in the region, in particular of recurrences of SA.

METHOD

We measured the evolution of the number of suicide attempts before and after implantation of VigilanS, using two types of analysis: a first from the national medical information systems in Medicine-Surgery-Obstetrics (PMSI-MCO) and a second from the collection of the ER stays for SA in the hospitals involved in the VigilanS program.

RESULTS

In 2014 (year before start of VigilanS), a total of 10 119 ER stays for SA was observed (5626 women and4463 men); in 2017, the total was 9.230 stays for SA (5047 women and 3 839 men), representing a decrease of 13.5%. The reduction was balanced between men (-14%) and women (-10%). Based on the figures of PMSI, we see an acceleration of the reduction of stay for SA in the Nord-Pas-de-Calais after 2014 (-16% instead of -6%), instead of the two Picardy departments the most comparable which show a degradation of the phenomenon (+13%), and opposed to the Department of the Oise which shows a stable maintenance of the current decline (-12%).

CONCLUSION

These two indicators are imperfect, but evolution over three years since the implementation of VigilanS goes in the same direction. We find a uncoupling of a hospital stay in connection with a SA. The intensity of this decline seems correlated to the penetrance of the program.

Work intensity in men and work-related emotional demands in women are associated with increased suicidality among persons attending primary care

BACKGROUND

A large proportion of persons died by suicide are employed at the time of death and work-related factors partly contribute to suicide risk. Our aim was to examine the association between multiple aspects of work organization and suicidal ideation in a study conducted in primary care.

METHODS

Data came from a study of 2027 working patients attending a GP representative of patients in the Nord Pas-de-Calais region in France (April-August 2014). Suicidality was assessed using the MINI (Mini International Neuropsychiatric Interview). Six emergent worked-related factors were explored (work intensity, emotional demands, autonomy, social relationships at work, conflict of values, insecurity of work). Several covariates were considered: patient's and GP's characteristics, and area-level data (material and social deprivation, psychiatrist and GPs' density, suicide attempts and suicide rates).

RESULTS

8.0% of participants reported suicidal ideation in the preceding month (7.5% of men and 8.6% of women, p = .03). In multivariate analyses adjusted for covariates, suicidality was significantly associated with work intensity (OR = 1.65; 95%CI [1.18-2.31]) in men and with work-related emotional demands (OR = 1.35; 95%CI [1.01-1.80]) in women. Area-level data were not associated.

LIMITATIONS

Our cross-sectional study cannot assess the direction of the relationships under study.

CONCLUSION

Our results emphasise a central role for GPs in suicide prevention among workers and highlight the importance of work-related factors with regard to suicidality in primary care.

Substrate use in horses during exercise - the ‘fasted’ compared to the postprandial state

Training in the fasted state has beneficial effects on performance in the human athlete. In the horse, training in the fasted state is associated with an increased mobilization of non-esterified fatty acids (NEFA) as an energy source. This is in contrast with postprandial (grain-fed) training, during which lipolysis is suppressed. A higher NEFA availability is thought to reduce muscle glycogen depletion and muscle acidification. This could aid in delaying muscle fatigue. The equine gastrointestinal tract and roughage rich diet do not allow a real ‘fasted’ state. Luckily, roughage does not induce high plasma insulin peaks, and therefore does not have the same negative effects as grain feeding. Furthermore, the roughage-containing hindgut serves as a fluid and electrolyte buffer and continuously provides the liver with propionic acid, a precursor used in gluconeogenesis. In horses, unlike in human athletes, there is still a lot to discover when it comes to optimal pre-exercise feeding management throughout competition and training. However, whatever approach is chosen, high quality roughage needs to be the key ingredient of the equine diet. In sport horses with high energy demands, feeding good quality roughage may be combined with fibre rich concentrates, pelleted roughages sources or vegetal oil instead of starch rich concentrates to reach the energy requirements for intensive work. Last but not least, feeding multiple small meals throughout the day is preferred over feeding a larger meal twice a day.

Effects of training on equine muscle physiology and muscle adaptations in response to different training approaches

It is well known that exercise induces chemical, metabolic and structural changes in muscles. However, the effect of the type of exercise on these changes has not been thoroughly studied in horses yet, because of a lack of standardized study methods. In this review, the effect of three different types of exercise on muscle adaptation and metabolic responses is investigated. The requirements for power exercise are not the same as for low intensity exercise. Each type of training induces its own shift in muscle fiber typing, as well as in enzyme concentrations and (an) aerobic capacity. These physiological adaptations in response to training facilitate more efficient exercise and therefore increase performance. Hence, it is important to know the adaptations that muscles undergo in response to each type of exercise to optimize training management of sport horses in function of the needs of the discipline in which they compete.

Standardized exercise tests in horses: current situation and future perspectives

The purpose of this literature review is to clarify how exercise capacity can be measured in horses and which standardized exercise tests (SETs) exist. In this review, the measurement of the exercise capacity of horses is discussed and the standardized exercise tests (SET) are described. Two main types of SETs are used. Laboratory or treadmill tests are easy to standardize and provide more options to use all kinds of measuring devices, since the horse stays on the treadmill. On the other hand, field tests are conducted under the natural conditions associated with the specific sports discipline, and are easier to implement in the training schedule. However, field tests encompass interfering variables, such as weather conditions, ground surface conditions and the rider or jockey. Several variables are measured in order to calculate the fitness level which may be expressed by different parameters, such as V200 (speed at a heart rate of 200 beats per minute), Vla4 (speed at a blood lactic acid level of 4 mmol/L) and VO2max (maximum oxygen uptake).

[Long-term psychiatric hospitalizations]

BACKGROUND

Long-term hospitalizations in psychiatry raise the question of desocialisation of the patients and the inherent costs.

METHODS

Individual indicators were extracted from a medical administrative database containing full-time psychiatric hospitalizations for the period 2011-2013 of people over 16 years old living in the French region of Nord-Pas-de-Calais. We calculated the proportion of people who had experienced a hospitalization with a duration of 292 days or more during the study period. A bivariate analysis was conducted, then ecological data (level of health-care offer, the deprivation index and the size of the municipalities of residence) were included into a multilevel regression model in order to identify the factors significantly related to variability of long-term hospitalization rates.

RESULTS

Among hospitalized individuals in psychiatry, 2.6% had had at least one hospitalization of 292 days or more during the observation period; the number of days in long-term hospitalization represented 22.5% of the total of days of full-time hospitalization in psychiatry. The bivariate analysis revealed that seniority in the psychiatric system was strongly correlated with long hospitalization rates. In the multivariate analysis, the individual indicators the most related to an increased risk of long-term hospitalization were: total lack of autonomy (OR=9.0; 95% CI: 6.7-12.2; P<001); diagnoses of psychological development disorders (OR=9.7; CI95%: 4.5-20.6; P<.001); mental retardation (OR=4.5; CI95%: 2.5-8.2; P<.001): schizophrenia (OR=3.0; CI95%: 1.7-5.2; P<.001); compulsory hospitalization (OR=1.7; CI95%: 1.4-2.1; P<.001); having experienced therapeutic isolation (OR=1.8; CI95%: 1.5-2.1; P<.001). Variations of long-term hospitalization rates depending on the type of establishment were very high, but the density of hospital beds or intensity of ambulatory activity services were not significantly linked to long-term hospitalization. The inhabitants of small urban units had significantly less risk of long-term hospitalization than those of large cities. We found no influence of material and social deprivation in the long-term hospitalizations.

CONCLUSION

Long-term hospitalization in psychiatry only concerns a minority of patients but represents the fifth of the total number of days of full-time hospitalization. The recent patients were significantly less exposed to the risk of having a long-term hospitalization.

Analyse de certificats de décès de patients souffrant de maladie mentale

Introduction

De nombreuses études ont montré que la mortalité chez les patients souffrant de maladies mentales est 2 à 6 fois plus élevée qu’en population générale [1] et que l’espérance de vie est diminuée de 15 à 20 ans [2–4].

Méthodologie

L’objectif de cette étude consiste à comparer les causes de décès et les comorbidités, à partir de certificats de décès, d’une cohorte de patients souffrant de maladies mentales ayant été hospitalisés dans un établissement public en santé mentale à celles de la population générale d’une même région sur une période déterminée [5].

Résultats

Quatre cent soixante-treize certificats de décès d’une cohorte de patients souffrant de maladies mentales, hospitalisés dans un établissement public en santé mentale, dans le département du nord, ont été analysés entre 2004 et 2011. L’âge moyen de décès retrouvé est de 54,6 ans (± 15,6). L’indice comparatif de mortalité (ICM) est de 389 (356–426) pour toutes causes de décès. La surmortalité des patients est observée pour tous types de cause. Pour les causes naturelles, les décès par pathologies pulmonaires sont 3 fois plus élevées (ICM = 323[208–501]) et ceux par pathologies cardiovasculaires, 2 fois plus élevées (ICM = 213[163–277]). Le nombre de comorbidités varie entre 3 et 4 pour 50 % des certificats de décès.

Conclusion

Il s’agit d’une étude fiable et reproductible, utilisant une méthodologie originale. Cette étude met en évidence, chez les patients souffrant de maladies mentales, un âge prématuré de mortalité. Les causes de mortalité sont les mêmes chez les patients qu’en population générale mais avec une fréquence plus élevée. On relève autant de comorbidités sur les certificats de décès de patients qu’en population générale, mais survenant à des âges beaucoup plus précoces chez les patients. Ces résultats soulèvent la question de la qualité du suivi somatique de ces patients.

Mice engineered for an obligatory Mdm4 exon skipping express higher levels of the Mdm4-S isoform but exhibit increased p53 activity

Mdm4, a protein related to the ubiquitin-ligase Mdm2, is an essential inhibitor of tumor suppressor protein p53. In both human and mouse cells, the Mdm4 gene encodes two major transcripts: one encodes the full-length oncoprotein (designated below as Mdm4-FL), whereas the other, resulting from a variant splicing that skips exon 6, encodes the shorter isoform Mdm4-S. Importantly, increased Mdm4-S mRNA levels were observed in several human cancers, and correlated with poor survival. However, the role of Mdm4-S in cancer progression remains controversial, because the Mdm4-S protein appeared to be a potent p53 inhibitor when overexpressed, but the splice variant also leads to a decrease in Mdm4-FL expression. To unambiguously determine the physiological impact of the Mdm4-S splice variant, we generated a mouse model with a targeted deletion of the Mdm4 exon 6, thereby creating an obligatory exon skipping. The mutant allele (Mdm4(ΔE6)) prevented the expression of Mdm4-FL, but also led to increased Mdm4-S mRNA levels. Mice homozygous for this allele died during embryonic development, but were rescued by a concomitant p53 deficiency. Furthermore in a hypomorphic p53(ΔP/ΔP) context, the Mdm4(ΔE6) allele led to p53 activation and delayed the growth of oncogene-induced tumors. We next determined the effect of Mdm4(+/ΔE6) heterozygosity in a hypermorphic p53(+/Δ31) genetic background, recently shown to be extremely sensitive to Mdm4 activity. Mdm4(+/ΔE6) p53(+/Δ31) pups were born, but suffered from aplastic anemia and died before weaning, again indicating an increased p53 activity. Our results demonstrate that the main effect of a skipping of Mdm4 exon 6 is not the synthesis of the Mdm4-S protein, but rather a decrease in Mdm4-FL expression. These and other data suggest that increased Mdm4-S mRNA levels might correlate with more aggressive cancers without encoding significant amounts of a potential oncoprotein. Hypotheses that may account for this apparent paradox are discussed.
