In health services research, the health care of the population is examined under everyday conditions. Scientific questions include medical, patient-oriented, system-, performance- and quality-related as well as health economics topics. In health services research, complex interventions, e.g., treatment concepts with multiple therapy components, and/or across multiple sectors, are often implemented. The design of studies in health services research is based on the research question, the setting, and the available data, which can come from a variety of sources.

Background: Interdisciplinary multimodal pain therapy (IMPT) is an established treatment for patients with severe chronic pain. Little evidence is available on the role of treatment dosage and, in particular, on the association between the duration of IMPT and treatment outcome.

Aim: The aim of this retrospective study was to compare the medium-term treatment success of a short inpatient (SIT, 1 week) and a long outpatient (LOT, 4 weeks) IMPT with a comparable treatment concept and comparable therapy intensity (20 h/week) in patients with severe chronic pain.

Methods: Patients in both groups completed the German Pain Questionnaire at the beginning and end of IMPT as well as after 3 months. Primary outcome measures included pain-related impairment and average pain intensity at follow-up in patients of comparable sex, age as well as pain intensity and impairment at the beginning of the therapy.

Results: While both groups initially showed significant treatment effects in pain-related impairment and average pain intensity, LOT patients (n = 32) reported significantly better values in both variables at 3‑month follow-up compared with SIT patients (n = 32). This was due to sustained positive effects in LOT patients and worsening in the SIT group.

Conclusion: The results indicate that initial treatment effects can be observed in both treatment settings, but a longer duration of therapy seems to favour the long-term stability of treatment effects.

Background: The outcome domains pain intensity, pain-related interference, side effects, (treatment) information, participation and personal interaction have all been identified as relevant factors in the management of perioperative pain. However, it is not yet clear which of these are particularly significant for the subjectively perceived overall quality of postoperative pain management.

Aim: A newly developed questionnaire was used in this cross-sectional study to assess the relevance of these domains for patients and compare the relevance to healthcare professionals (HCP).

Methods: The patient survey (n = 40) was conducted on the first postoperative day at Jena University Hospital, Germany. In order to investigate group differences, 63 HCP (disciplines: n = 15 anaesthesiology, n = 17 surgery, n = 31 nursing) were recruited. The questionnaire primarily included all pairwise comparisons between the domains with regard to the overall quality of postoperative pain management. The resulting sum scores for each domain were the primary outcome measure, which were analysed using generalized estimating equations.

Results: Within the group of patients, there were significant differences in the prioritization of the six outcome domains, with personal interaction followed by intensity and interference having received the highest ratings. There were also significant differences within the domains between the perspectives of patients and HCP, as well as between the HCP themselves.

Conclusions: The study demonstrates that personal interaction and the reduction of pain intensity and interference are three key factors that are significant for patients' experience of postoperative pain management. However, the extent to which the harmonisation of these three factors with those given prominence by HCP would positively impact postoperative pain management remains unclear and should be investigated further.

Background: With the help of specialized outpatient palliative care teams (German abbreviation: SAPV), seriously ill and dying patients in Germany can be adequately cared for in their home environment until the end of their lives; however, there are no uniform standards or guidelines for well-executed pain management right now.

Objective: This approach serves as basic research in the field of public health research. This is intended to present which methods (use of different professional groups, use of pain medications, alternative medical treatment etc.) the individual SAPV teams use for pain management. From this it can be deduced which procedures can be considered particularly effective.

Material and methods: This cross-sectional study was conducted in May 2021. All German SAPV teams (n = 307) listed on the homepage of the German Association for Palliative Medicine (DGP) were contacted by post and invited to participate. A total of 175 teams (57%) responded to the request and were included in the evaluation. A descriptive data analysis was performed.

Results: Pain management in the German outpatient care of palliative patients is based on several components. All common pain medications are used, but primarily metamizole (99.4%) as a non-opioid analgesic, morphine (98.3%) from the opiate series and pregabalin (96.6%) as a co-analgesic are mainly prescribed. If pain therapy fails, 22.5% of the SAPV teams perform palliative sedation for symptom control on a regular basis.

Conclusion: This cross-sectional study is the first of its kind to provide a general overview of the treatment options for pain management in German outpatient palliative care. In comparison with international studies, the question arises as to whether uniform therapy schemes and a reduction in the medication available in the individual SAPV teams could lead to an improvement in patient care.

Background: Disorders of the upper cervical spine, most notably lesions of the alar ligament and atlas block, are associated with numerous symptoms, especially as reported in the lay press. Thus, physicians are often confronted with patients who see in them a monocausal origin of complex complaints and hope for a quick remedy.

Objective: This review article presents the currently available evidence-based literature on atlas block and alar ligament lesions in order to adequately appreciate their significance.

Material and methods: Summary and critical evaluation of an extensive review of the literature on the diagnostics, clinical presentation, and treatment of disorders of the upper cervical spine.

Results: The current literature shows that alar ligament lesions are caused only by extremely high-speed trauma and that the reliability of their detection on magnetic resonance imaging (MRI) is moderate at best. As several studies have failed to demonstrate a correlation between symptoms and abnormalities of the alar ligaments on MRI, surgical stabilization of the upper cervical joints is not indicated. The diversity of symptoms associated with atlas block may be explained by the convergence of afferent neurons originating in C1-C3 on several cranial nerve nuclei found in neuroanatomical studies, but this association has yet to be proven. First studies show that highly significant improvements in cervical pain and range of motion can be achieved by means of manual therapy of the upper cervical spine with lasting effects even after 6 months.

Conclusion: The importance of alar ligament lesions has often been overrated in the past; however, a more nuanced multifactorial understanding of the disorder should be conveyed to the patient. An atlas block should be considered mainly as a possible cause of pain and restricted range of motion of the cervical spine and in this context manual therapy can be an effective treatment option.

If we understand chronic pain not only as a disease but also as an existential crisis, it seems logical and reasonable to consider spiritual aspects in the treatment process. Spirituality is understood as an umbrella term for all activities and experiences that give meaning and significance to people's lives-irrespective of their religious affiliation. So far, spiritual aspects have been considered therapeutically mainly in the palliative context. According to current survey-based studies of pain patients, the inclusion of spiritual themes in therapy leads to an improvement in quality of life and pain tolerance and is moreover explicitly desired by those patients. A consistent expansion of multimodal treatment approaches in the sense of a biopsychosocial-spiritual concept has not yet been implemented. The following basic attitudes and behaviors are relevant for practical implementation: openness to spiritual themes and authenticity, taking a spiritual history, listening, standing firm, activation of values, use of motives from religion, mythology, and art. Professional competence generally involves all practitioners, but may also require qualified professionals for specialized assistance. The integration of authentic spiritual assistance into multimodal pain management should help to stabilize self-esteem and the experience of identity of the patients through resource activation and identification of burdensome spiritual beliefs. The detailed integration and investigation of the efficiency of spiritual interventions in multimodal pain therapy require further research.

Background: The transition from acute to non-specific chronic low back pain (CLBP) is especially associated with psychological factors. However, working mechanisms of psychological factors have been little examined in non-specific CLBP, especially the mediator effect of pain self-efficacy.

Objective: Does pain self-efficacy mediate the long-term prediction of work-related factors by depressive symptoms?

Methods: Within the framework of an exploratory secondary analysis, simple mediation analyses were conducted to longitudinally predict prognosis of gainful employment, as well as subjective physical and mental work ability by depressive symptoms mediated by pain self-efficacy in 382 inpatients with non-specific CLBP.

Results: The findings suggest that depressive symptoms prior to rehabilitation predicted levels of all three work-related factors 24 months after rehabilitation, and pain self-efficacy 12 months after rehabilitation mediated this relationship.

Conclusion: To improve the success of work-related rehabilitation in the long-term, pain self-efficacy in particular, but also depressive symptoms should be targeted by treatments of non-specific CLBP.
