Concerns About Psychiatric Neurosurgery and How They Can Be Overcome: Recommendations for Responsible Research

Background

Psychiatric neurosurgery is experiencing a revival. Beside deep brain stimulation (DBS), several ablative neurosurgical procedures are currently in use. Each approach has a different profile of advantages and disadvantages. However, many psychiatrists, ethicists, and laypeople are sceptical about psychiatric neurosurgery.

Methods

We identify the main concerns against psychiatric neurosurgery, and discuss the extent to which they are justified and how they might be overcome. We review the evidence for the effectiveness, efficacy and safety of each approach, and discuss how this could be improved. We analyse whether and, if so, how randomised controlled trials (RCTs) can be used in the different approaches, and what alternatives are available if conducting RCTs is impossible for practical or ethical reasons. Specifically, we analyse the problem of failed RCTs after promising open-label studies.

Results

The main concerns are: (i) reservations based on historical psychosurgery, (ii) concerns about personality changes, (iii) concerns regarding localised interventions, and (iv) scepticism due to the lack of scientific evidence. Given the need for effective therapies for treatment-refractory psychiatric disorders and preliminary evidence for the effectiveness of psychiatric neurosurgery, further research is warranted and necessary. Since psychiatric neurosurgery has the potential to modify personality traits, it should be held to the highest ethical and scientific standards.

Conclusions

Psychiatric neurosurgery procedures with preliminary evidence for efficacy and an acceptable risk–benefit profile include DBS and micro- or radiosurgical anterior capsulotomy for intractable obsessive–compulsive disorder. These methods may be considered for individual treatment attempts, but multi-centre RCTs are necessary to provide reliable evidence.

Willingness to pay for a quality-adjusted life year for depressive disorders compared to heart disease based on population preferences

PURPOSE

According to estimations of the World Health Organization, depressive disorders, and cardiovascular disease will be the leading causes for global burden of disease in 2030. The aim of the present study was to estimate the value a representative sample of the German population places on quality-adjusted life years (QALYs) for depressive disorders compared to heart disease.

METHODS

A representative sample of N = 967 of the German general public was randomly presented with one of two hypothetical health-loss scenarios: One version of the questionnaire presented respondents with health loss due to depression, while the other version dealt with health loss due to experiencing a heart disease. Respondents were asked to indicate their willingness to pay (WTP) for four hypothetical health-gain scenarios with different treatment options.

RESULTS

In the depression questionnaire median WTP values ranged from 1000 to 1500 EUR; in the heart disease questionnaire from 1000 to 2000 EUR. Results of the Mann-Whitney U-Test and Median Test indicate higher WTP values for heart disease compared to depressive disorders when QALY gains were minor and stretched over a long period of time, and when treatment with bypass operation (rather than treatment with ECT) was offered. Zero WTP was significantly higher in all scenarios of the depression questionnaire in comparison to the hearth disease questionnaire.

CONCLUSION

Results indicate that respondents valued the necessity of paying for treatment higher when presented with heart disease compared to depression.

[Benefits and risks of psychiatric actions and the patient's right of self-determination]

The history of psychiatry shows that a right of self-determination of the mentally ill was widely unknown in the nineteenth century and became known in medicine through the juridical concept of informed consent as late as in the second half of the twentieth century. Since the beginning of the twenty-first century this human right has been increasingly recognized and respected in medical practice. This change of recognition is contributing to a change from a paternalistic to a participative medical attitude. In the context of an emancipatory development of society the increasing possibilities of effective therapies, which are rarely without risks, stimulate the necessity to inform the patient about the intended benefits and the potential risks of the recommended intervention. This gives the patient the opportunity to exercise the right of self-determination. Furthermore, by the transition from very successful acute medicine, although often with only short-term contact between physician and patient to long-term therapies of chronic diseases, the possibilities to understand the patient are increased, particularly in the mentally ill patient. This also enables the individual characteristics to be recognized better, both the restrictions and capabilities, to experience the patient as an individual, as a human being with individual peculiarities and to respect the right of self-determination by helping the patient to understand the benefits and risks of a recommended intervention and to balance them in a self-determined mode.

[Importance of electroconvulsive therapy (ECT) in forensic psychiatry]

Hintergrund und Ziel der Arbeit

Für die Elektrokonvulsionstherapie (EKT) liegen Leitlinienempfehlungen zur Behandlung schwerer affektiver und psychotischer Erkrankungen vor, wie sie auch bei Patienten im Maßregelvollzug (MRV) vorkommen. Über die Anwendung der EKT in der forensischen Psychiatrie existieren jedoch keinerlei systematisch erhobene Daten. Ziel der vorliegenden Arbeit ist eine Erhebung des Ist-Zustands sowie des geschätzten Bedarfs an EKT im MRV.

Material und Methoden

Es wurde ein Fragebogen zur Erhebung der aktuellen Anwendung sowie der Einschätzung des Bedarfs an EKT in dieser Population entwickelt. Dieser wurde elektronisch und bei Bedarf postalisch an die forensischen Kliniken in Deutschland versendet.

Ergebnisse

Wir erhielten Antwort von 52 Kliniken (66 %). 29 der Kliniken gaben an, Patienten mit EKT behandeln zu können. Eine Behandlungsindikation wurde klinikübergreifend für 3,4 % der untergebrachten Patienten gesehen. In einem Jahr (2018) wurden insgesamt 32 EKT-Behandlungen an 12 Kliniken des Maßregelvollzugs mit durchschnittlich guter Wirksamkeit (Ø CGI‑I 2,32) durchgeführt. Häufigste Begründung für die fehlende Anwendung der EKT waren mangelnde strukturelle Voraussetzungen. Jeweils etwa ein Drittel der Kliniken sehen einen mittleren bzw. hohen Bedarf an EKT im MRV.

Diskussion

Die EKT kommt im MRV in Deutschland aktuell nur sehr begrenzt zum Einsatz. Auffällig ist, dass die Anzahl der durchgeführten Behandlungen etwa um den Faktor 8 hinter der Indikationshäufigkeit zurücksteht. Ungeachtet dessen sehen zwei Drittel der Kliniken einen mittleren bis hohen Bedarf, womit eine Unterversorgung mit EKT im MRV zu bestehen scheint.
