The prevalence, diagnostics and therapy of the burnout syndrome are increasingly discussed in the public. The unclear definition and diagnostics of the burnout syndrome are scientifically criticized. There are several therapies with unclear evidence for the treatment of burnout in existence.
The health technology assessment (HTA) report deals with the question of usage and efficacy of different burnout therapies.
For the years 2006 to 2011, a systematic literature research was done in 31 electronic databases (e.g. EMBASE, MEDLINE, PsycINFO). Important inclusion criteria are burnout, therapeutic intervention and treatment outcome.
17 studies meet the inclusion criteria and are regarded for the HTA report. The studies are very heterogeneous (sample size, type of intervention, measuring method, level of evidence). Due to their study design (e.g. four reviews, eight randomized controlled trials) the studies have a comparable high evidence: three times 1A, five times 1B, one time 2A, two times 2B and six times 4. 13 of the 17 studies are dealing with the efficacy of psychotherapy and psychosocial interventions for the reduction of burnout (partly in combination with other techniques). Cognitive behaviour therapy leads to the improvement of emotional exhaustion in the majority of the studies. The evidence is inconsistent for the efficacy of stress management and music therapy. Two studies regarding the efficacy of Qigong therapy do not deliver a distinct result. One study proves the efficacy of roots of Rhodiola rosea (evidence level 1B). Physical therapy is only in one study separately examined and does not show a better result than standard therapy.
Despite the number of studies with high evidence the results for the efficacy of burnout therapies are preliminary and do have only limited reach. The authors of the studies complain about the low number of skilled studies for the therapy of burnout. Furthermore, they point to the insufficient evaluation of the therapy studies and the need for further research. Some authors report the effects of considerable natural recovering. Numerous limitations affect the quality of the results. Intervention contents and duration, study design and study size are very diverse and do not permit direct comparison. Most of the samples are small by size with low statistical power, long-term follow-ups are missing. Comorbidities and parallel utilized therapies are insufficient documented or controlled. Most of the studies use the Maslach Burnout Inventory (MBI) as diagnostic or outcome-tool, but with different cut-off-points. It should be noticed that the validity of the MBI as diagnostic tool is not proved. Ethical, juridical and social determining factors are not covered or discussed in the studies.
The efficacy of therapies for the treatment of the burnout syndrome is insufficient investigated. Only for cognitive behavioural therapy (CBT) exists an adequate number of studies which prove its efficacy. Big long-term experimental studies are missing which compare the efficacy of the single therapies and evaluate their evidence. The natural recovering without any therapy needs further research. Additionally, it has to be examined to what extent therapies and their possible effects are thwarted by the conditions of the working place and the working conditions.
职业倦怠综合征的患病率、诊断和治疗在公众中讨论得越来越多。职业倦怠综合征定义和诊断不明确受到了科学界的批评。目前存在几种治疗职业倦怠的疗法,但证据尚不明确。
健康技术评估(HTA)报告探讨了不同职业倦怠疗法的使用情况和疗效问题。
对2006年至2011年期间在31个电子数据库(如EMBASE、MEDLINE、PsycINFO)中进行了系统的文献研究。重要的纳入标准是职业倦怠、治疗干预和治疗结果。
17项研究符合纳入标准并被纳入HTA报告。这些研究差异很大(样本量、干预类型、测量方法、证据水平)。由于其研究设计(如4篇综述、8项随机对照试验),这些研究具有相当高的证据水平:3次为1A,5次为1B,1次为2A,2次为2B,6次为4。17项研究中有13项涉及心理治疗和社会心理干预对减轻职业倦怠的疗效(部分与其他技术联合使用)。在大多数研究中,认知行为疗法能改善情感耗竭。压力管理和音乐疗法疗效的证据不一致。两项关于气功疗法疗效的研究未得出明确结果。一项研究证明红景天根的疗效(证据水平1B)。物理治疗仅在一项研究中单独进行了检验,结果并不比标准治疗更好。
尽管有大量高证据水平的研究,但职业倦怠疗法疗效的结果仍是初步的,且范围有限。这些研究的作者抱怨针对职业倦怠治疗的高质量研究数量不足。此外,他们指出治疗研究评估不足,需要进一步研究。一些作者报告了相当可观的自然恢复效果。许多限制因素影响了结果的质量。干预内容和持续时间、研究设计和研究规模差异很大,无法直接比较。大多数样本量小,统计效力低,缺乏长期随访。合并症和同时使用的其他疗法记录或控制不足。大多数研究使用马氏职业倦怠量表(MBI)作为诊断或结果工具,但截断点不同。应注意的是,MBI作为诊断工具的有效性尚未得到证实。研究未涵盖或讨论伦理、法律和社会决定因素。
职业倦怠综合征治疗方法的疗效研究不足。只有认知行为疗法(CBT)有足够数量的研究证明其疗效。缺乏大型长期实验研究来比较单一疗法的疗效并评估其证据。未经任何治疗的自然恢复情况需要进一步研究。此外,还必须研究工作场所条件和工作环境在多大程度上阻碍了治疗及其可能的效果。
