    ABSTRACT: To determine whether ambulatory psychotherapy targeted to abandonment experiences and fears can reduce suicidality and improve outcome in borderline patients referred to the emergency room with major depressive disorder and self-destructive behavior severe enough to require medical/surgical treatment and a brief psychiatric hospitalization. A total of 170 subjects were randomized at hospital discharge into three treatment groups: treatment as usual (TAU), abandonment psychotherapy delivered by certified psychotherapists, and abandonment psychotherapy delivered by nurses. Assessments were performed before randomization and at 3-month follow-up. Continued suicidality and other outcome measures were significantly worse in the treatment-as-usual as compared to both abandonment psychotherapy groups, but there were no differences between the two psychotherapy groups. These results suggest the efficacy of manualized psychotherapy that specifically targets the abandonment fears and experiences that are so common as precipitants to suicidal and self-destructive acts in borderline patients. It does not appear that formal psychotherapy training is associated with better outcomes.

    ABSTRACT: This study investigated whether crisis intervention (CI) at the General Hospital is a suitable management strategy among borderline patients referred to the emergency room (ER) for deliberate self-harm. Two patient cohorts (n=200) meeting DSM-IV Borderline Personality Disorder criteria, were prospectively assessed for repeated deliberate self-harm and service consumption. At ER discharge, 100 subjects received CI, while 100 comparison subjects (recruited before the implementation of CI) were assigned to treatment as usual (TAU). At 3-month follow-up, a high proportion of repeated deliberate self-harm and hospitalization in the global study sample was found. However rates were lower in the CI group: 8% repeated deliberate self-harm and 8% psychiatric hospitalization, versus 17% and 56% in the TAU group. The global expenditure for psychiatric hospitalization was 728,840 Swiss Francs (CHF) for CI and 914,340 for TAU. This study indicates that associated with mean hospitalization/relapse rates, CI may be a suitable management strategy for acutely suicidal borderline patients.

    ABSTRACT: Recent research indicated that the outcome of borderline patients is better than previously reported. We assessed the impact of co-morbid personality disorders (PD) on response to treatment and 1-year outcome among 206 borderline patients assigned to crisis intervention program. An overwhelming majority (89%) of borderline patients without supplementary Axis 11 psychopathology exhibited good to very good treatment response at acute treatment discharge as well as good to very good global outcome at 1-year followup (85%). Borderline patients meeting criteria for paranoid, schizotypal, antisocial, narcissistic and dependant personality disorder showed, contrarily, significantly more treatment failures.

    ABSTRACT: Over the last few years, a new comprehensive program for acutely suicidal borderline patients has been developed in the Geneva area (careful description is provided in a distinct section of this workshop). The present work will report the results of a service research oriented study aimed at evaluating the impact of the implementation of such multidimensional intervention on a system of psychiatric services in a 500.000 inhabitant catchment area. Specifically, a pre-post design has been utilized to compare two distinct patient cohorts meeting criteria for borderline personality disorder who had bee referred to medical emergency room with suicidal attempt. Both cohorts had follow-up at 3-month and 1 year to assess treatment failure, repetition, hospitalization and direct costs. The results indicate that the program is feasible and may be associated with improved outcome and substantial costs savings among acutely suicidal borderline patients.

    ABSTRACT: Background Psychoanalytic psychotherapy was found superior to usual treatment among borderline patients and should be further investigated in subject samples with adequate adherence to effective treatment and careful evaluation of psychotherapy process and its relationship to outcome. According to this rationale we tested the comparative cost-effectiveness of an innovative model of time limited psychoanalytic psychotherapy aimed at working-out conflicting mourning process associated with traumatic abandonment from a romantic partner. Methods Eighty patients aged 18-60, who had been referred to medical emergency room with self-intoxication, DSMIV-R major depression and DSMIV-R borderline personality disorder were investigated in a 3-month randomized clinical trial. At general hospital discharge consecutive subjects were allocated to time-limited mourning focused psychoanalytic psychotherapy and venlafaxine and psychodynamic crisis intervention and venlafaxine. Reliable evaluations were conducted at intake, treatment discharge and 6-month follow-up on a battery of standardized instruments. Service consume was assessed via the computerized case register of the Geneva state health services system. Results Intensive psychoanalytic psychotherapy was found a cost-effective treatment choice among borderline patients in a suicidal crisis. Comment A combination of ambulatory psychoanalytic psychotherapy and venlafaxine protocol is a feasible, safe and cost-effective treatment for acutely suicidal borderline patients.

    ABSTRACT: This paper aims at investigating causes and potential remedies of increased psychiatric hospitalization in this country. The data suggest that there was growing pressure on psychiatric hospitals from 1950 to 2000. This may result from inappropriate management of a new type of acute psychiatric patient rather than severed epidemiology of acute psychiatric disorders. More focus on innovative crisis intervention programs emphasizing the central role of the general hospital in contemporary psychiatry may strongly contribute to better mental care. Despite significant advances in psychotherapy and medical research such an evolution is contended from the exquisite entropy of psychiatric systems. Those cultural and psychological factors associated with this issue require careful consideration and further studies.

    ABSTRACT: Suicidal attempts are not rare in the general population (about 4.5%) and the presence of personality disorder aggravates the clinical issue of these patients who also repeat suicidal attempts. Caring for these patients is particularly difficult for physicians and other caregivers, in the means of choice of specific treatment and prevention of relapse. Despite the existence of many psychiatric facilities that can welcome these patients, there is a high rate of treatment failure or drop-out. This constitutes a major issue for systems of care politics. This article describes a specific form of treatment, psychotherapeutic and risk-management oriented, of borderline patients with suicidal attempt admitted at the ER.

    ABSTRACT: Stalking is a recently described syndrome including a pattern of repeated intrusion and seeking for intimate relationship with another person that is unwanted. Such behaviour is perceived as an explicit threat from a victim who experiences fear. Recent studies indicate that stalking is an important legal and clinical issue with elevated prevalence rates especially among women (10%) eventually with dramatic consequences. Furthermore stalking situation are important in psychiatric practice especially among patients referred to emergency room and crisis intervention. A specific form of "treatment barrier" comes along with stalking and will be discussed. Judiciary actions are often necessary before it is possible to plan a treatment.
