Crisis interventions for adults with borderline personality disorder.

BACKGROUND: People diagnosed with borderline personality disorder (BPD) frequently present to healthcare services in crisis, often with suicidal thoughts or actions. Despite this, little is known about what constitutes effective management of acute crises in this population and what type of interventions are helpful at times of crisis. In this review, we will examine the efficacy of crisis interventions, defined as an immediate response by one or more individuals to the acute distress experienced by another individual, designed to ensure safety and recovery and lasting no longer than one month. This review is an update of a previous Cochrane Review examining the evidence for the effects of crisis interventions in adults diagnosed with BPD. OBJECTIVES: To assess the effects of crisis interventions in adults diagnosed with BPD in any setting. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, nine other databases and three trials registers up to January 2022. We also checked reference lists, handsearched relevant journal archives and contacted experts in the field to identify any unpublished or ongoing studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing crisis interventions with usual care, no intervention or waiting list, in adults of any age diagnosed with BPD. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included two studies with 213 participants. One study (88 participants) was a feasibility RCT conducted in the UK that examined the effects of joint crisis plans (JCPs) plus treatment as usual (TAU) compared to TAU alone in people diagnosed with BPD. The primary outcome was self-harm. Participants had an average age of 36 years, and 81% were women. Government research councils funded the study. Risk of bias was unclear for blinding, but low in the other domains assessed. Evidence from this study suggested that there may be no difference between JCPs and TAU on deaths (risk ratio (RR) 0.91, 95% confidence interval (CI) 0.06 to 14.14; 88 participants; low-certainty evidence); mean number of self-harm episodes (mean difference (MD) 0.30, 95% CI -36.27 to 36.87; 72 participants; low-certainty evidence), number of inpatient mental health nights (MD 1.80, 95% CI -5.06 to 8.66; 73 participants; low-certainty evidence), or quality of life measured using the EuroQol five-dimension questionnaire (EQ-5D; MD -6.10, 95% CI -15.52 to 3.32; 72 participants; very low-certainty evidence). The study authors calculated an Incremental Cost Effectiveness Ratio of GBP -32,358 per quality-adjusted life year (QALY), favouring JCPs, but they described this result as "hypothesis-generating only" and we rated this as very low-certainty evidence.  The other study (125 participants) was an RCT conducted in Sweden of brief admission to psychiatric hospital by self-referral (BA) compared to TAU, in people with self-harm or suicidal behaviour and three or more diagnostic criteria for BPD. The primary outcome was use of inpatient mental health services. Participants had an average age of 32 years, and 85% were women. Government research councils and non-profit foundations funded the study. Risk of bias was unclear for blinding and baseline imbalances, but low in the other domains assessed. The evidence suggested that there is no clear difference between BA and TAU on deaths (RR 0.49, 95% CI 0.05 to 5.29; 125 participants; low-certainty evidence), mean number of self-harm episodes (MD -0.03, 95% CI -2.26 to 2.20; 125 participants; low-certainty evidence), violence perpetration (RR 2.95, 95% CI 0.12 to 71.13; 125 participants; low-certainty evidence), or days of inpatient mental health care (MD 0.70, 95% CI -14.32 to 15.72; 125 participants; low-certainty evidence). The study suggested that BA may have little or no effect on the mean number of suicide attempts (MD 0.00, 95% CI -0.06 to 0.06; 125 participants; very low-certainty evidence). We also identified three ongoing RCTs that met our inclusion criteria. The results will be incorporated into future updates of this review. AUTHORS' CONCLUSIONS: A comprehensive search of the literature revealed very little RCT-based evidence to inform the management of acute crises in people diagnosed with BPD. We included two studies of two very different types of intervention (JCP and BA). We found no clear evidence of a benefit over TAU in any of our main outcomes. We are very uncertain about the true effects of either intervention, as the evidence was judged low- and very low-certainty, and there was only a single study of each intervention. There is an urgent need for high-quality, large-scale, adequately powered RCTs on crisis interventions for people diagnosed with BPD, in addition to development of new crisis interventions.

At the limit? Using operational data to estimate train driver human reliability.

Human reliability analysis plays an important role in the safety assessment and management of rail operations. This paper discusses how the increasing availability of operational data can be used to develop an understanding of train driver reliability. The paper derives human reliability data for two driving tasks, stopping at red signals and controlling speed on approach to buffer stops. In the first of these cases, a tool has been developed that can estimate the number of times a signal is approached at red by trains on the Great Britain (GB) rail network. The tool has been developed using big data techniques and ideas, recording and analysing millions of pieces of data from live operational feeds to update and summarise statistics from thousands of signal locations in GB on a daily basis. The resulting driver reliability data are compared to similar analyses of other train driving tasks. This shows human reliability approaching the currently accepted limits of human performance. It also shows higher error rates amongst freight train drivers than passenger train drivers for these tasks. The paper highlights the importance of understanding the task specific performance limits if further improvements in human reliability are sought. It also provides a practical example of how big data could play an increasingly important role in system error management, whether from the perspective of understanding normal performance and the limits of performance for specific tasks or as the basis for dynamic safety indicators which, if not leading, could at least become closer to real time.

Improving medical students' confidence in end-of-life consultations.

BACKGROUND: End-of-life discussions are associated with improved quality of care for patients. In the UK, the General Medical Council outlines a requirement for medical graduates to involve patients and their families in discussions on their care at the end-of-life. However medical students feel ill-equipped to conduct these discussions. METHODS: In 2018, Sheffield Medical School introduced a small group role-play session on end-of-life discussions for all final year medical students. Scenarios were devised to improve confidence in the following learning domains: communicating prognosis with patients and family; ascertaining patient's goals, values and preferred place of death; discussing escalation of treatment, discussing do not attempt resuscitation orders, care in the dying phase of illness and pre-emptive prescribing. Evaluation was conducted over 16 weeks with a before and after questionnaire. Students rated their confidence in the above learning domains on a Likert-style scale and explained their ratings in free-text boxes. RESULTS: There was a 76% response rate to the questionnaire and analysis showed statistically significant improvements in confidence across all learning domains following the session. Qualitative analysis of free-text responses showed that prior to the sessions, students expressed low confidence due to lack of experience and fear of upsetting patients. After the session students felt they had gained skills but expressed persistent anxiety and a desire for further practice. CONCLUSIONS: Our innovation suggests that the opportunity to experience End-of-life discussions through role-play can significantly improve students' confidence in conducting these conversations. However, repeated sessions are likely necessary for students to feel prepared upon graduation.

The development of guidelines for the design and evaluation of warning signs for young children.

We report a study which aimed to provide further development and refinement of a set of guidelines (Waterson et al., 2012) for the design and evaluation of warning signs and other visual material for young children (i.e., aged 5-11 years). The study involved a set of semi-structured interviews and focus groups with the parents of young children, teachers, human factors experts and other groups (n = 38). The findings from the study provided broad support for the guidelines, as well as highlighting a number of issues which need to be addressed. These included the need to consider the target audience in more detail and provide additional guidance covering possible tie-ins with safety campaigns, sign location, age differences, gender and children's special needs. Similar findings were obtained with regard to the evaluation guidelines and their coverage of methods and activities for testing signs (e.g., simulation, role playing). We discuss our findings within the context of a revised set of guidelines and a set of suggestions aimed at working towards a more comprehensive approach to the design/evaluation of signs for young children. The paper concludes with a set of future topics for research including a discussion of ways forward in terms of improving support for design and evaluation including behavioural testing with children, their parents and other care givers.
