Abstract
PURPOSE The aim of this study was to investigate the relationship between pain duration and pain relief after epidural adhesiolysis. MATERIALS AND METHODS Patients with low back pain who underwent lumbar epidural adhesiolysis were enrolled. A clinically significant reduction in pain score was defined as a ≥30% reduction at 6-month follow-up evaluation. Variables were compared based on pain duration categories. Changes in pain scores and pain outcome were also compared. Logistic regression analysis was conducted to identify factors associated with pain relief after adhesiolysis. RESULTS A total of 169 patients, including 77 (45.6%) patients with a favorable pain outcome, were included for analysis. Patients with a pain duration ≥3 years reported lower baseline pain scores and showed more frequent severe central stenosis. Pain scores significantly decreased over time after the procedure except in patients with a pain duration ≥3 years. Most patients who experienced pain for ≥3 years showed poor pain relief (80.8%), unlike other pain duration categories (pain duration <3 months=48.1%, 3 months-1 year=51.8%, 1-3 years=48.6%). A pain duration ≥3 years and lower baseline pain score were independent factors associated with an unfavorable pain outcome. CONCLUSION Pain lasting ≥3 years prior to lumbar epidural adhesiolysis was associated with worse outcomes in terms of pain relief. Therefore, this intervention should be considered early before pain chronification in patients with low back pain.

Abstract
BACKGROUND Drug-induced constipation (DIC) is a well-known comorbidity of cancer pain, however, data on its prevalence in nonmalignant pain (NMP) and its biopsychosocial effects are few. OBJECTIVE To assess the prevalence and impact of DIC in patients with NMP. METHODS Exploratory noninterventional, retrospective, cross-sectional analysis of depersonalized routine data of the German Pain e-Registry on 150,488 NMP patients (EUPAS identifier: 42286). RESULTS DIC affects 33.5% of NMP patients. The most prevalent risk factors were the use of strong opioid analgesics and analgesic polymedication. Patients with DIC presented with significantly worse biopsychosocial scores as well as significantly higher percentages of individuals with severe deterioration of pain, daily life activities, physical and mental quality of life, mood, and overall wellbeing. Among patients with DIC, those who reported constipation as a clinical symptom and who documented bowel-function index (BFI) scores above the reference range were significantly more affected compared to those who either reported only constipation as an adverse event or elevated BFI scores. 55.9% of patients with DIC reported the use of laxatives, mostly over-the-counter preparations (43.6%), whereas prescription laxatives were taken by only 29.3%. CONCLUSIONS DIC is a frequent comorbidity of pain management and affects around one-third of patients with NMP. It interferes significantly with pain-related biopsychosocial effects and has to be addressed specifically to improve the overall burden in affected patients. However, the use of laxatives was significantly less frequent than recommended indicating significant room for improvement.

Abstract
Background and aims Evaluating the degree to which pain has become chronic beyond mere duration poses several problems. The IASP Pain Taxonomy Axis IV employs intensity and duration combined to nine ordered categories. The Chronic Pain Grade links intensity and disability, but only the latter contributes to higher grades. The Mainz Pain Staging System includes temporal and spatial aspects, medication and health care utilization. Their interrelations, scale properties and construct validity are not always known or debatable. The study challenges the generality and homogeneity of the chronicity construct of musculoskeletal pain aiming at necessary and sufficient sub-constructs identified by separable marker clusters. We show chronicity to vary in content and structure with severity and duration and between different populations. This raises the question of validity conditions of general chronicity indices and requires further work on adequate chronicity measures. Methods Diagnostic entrance data of 185 patients with chronic regional vs. widespread musculoskeletal pain (unspecific back pain, fibromyalgia) from regional pain clinics and 170 active employees in a nationwide prevention program were included in a retrospective cross-sectional analysis of the combined marker sets of the three chronicity indices above. The samples of patients and employees provided intensity, duration and disability degrees over the whole range of the assumed chronicity. Intensity-duration relations were quantified by correlations and frequency distributions of successive duration classes. The dimensional structure of pain and chronicity variables was assessed by factor and cluster analyses. Results Pain intensity distributions showed inhomogeneous courses from short to long durations - lowest intensities predominating at longer durations in patients and at shorter in employees. Moreover, pain intensity and duration related nonlinearly to Chronic Pain Grade and Mainz Pain Stage and differently in patients compared to employees, and these indices correlated only moderately to each other. Factor and cluster analyses revealed different dimensions and clusters of chronicity markers for patients and employees. In the former, three dimensions with four clusters were identified with clinical characteristics (intensity, temporal and spatial aspects) separated from direct consequences (disability/interference with activities, medication usage) and chronic development (duration, healthcare utilization). In employees, only two dimensions with three clusters were obtained and clinical pain characteristics clustered with direct consequences both separated from chronic development. Similar differences were shown between unspecific back pain and fibromyalgia but were less well defined. Conclusions There appears to be no coherent "chronicity" entity over the entire range of severity and duration for all pain populations with different clinical pictures and social contexts. Statements about chronicity must be differentiated with respect to those aspects relative to patient career. Implications General indices do not capture the complex and changing composition of chronicity. There is evidence for at least three weakly coupled core domains of chronicity, i.e. the primary clinical characteristics, the direct consequences of current interference with activities, and aspects of the patient history. Hence, multivariate assessment is recommended. The particular syndrome, the diagnostic context and the population under investigation should likewise be considered.

Abstract
A comparison of chronic pain patients in outpatient and inpatient treatment settings regarding pain-related and psychological characteristics, has not yet been systematically analyzed. The core documentation and quality assurance in pain therapy (KEDOQ-Schmerz) is a quality assurance system for documentation and quality management of pain therapy in different treatment settings. The system was initiated by the German Pain Society. We used KEDOQ-Schmerz data to describe differences between patients being treated in outpatient and inpatient settings with respect to social, pain-related and psychological factors. In total, the set of KEDOQ-Schmerz data analyzed included information from 4705 patients (from 13 clinics) collected between January 2012 and April 2016. Patients received either outpatient (n = 2682) or inpatient (n = 2023) treatment. The data analyzed comprised sociodemographic, pain-related and psychological data collected through the German Pain Questionnaire (DSF) at the beginning of treatment as well as information about pain chronification and pain localization provided by practitioners. The statistical analysis was carried out by descriptive and comparative data analysis using univariate and multivariate statistical methods. Patients with inpatient treatment were significantly older, more often female and more often had multiple pain localizations. They described stronger pain intensity and more frequently had a higher Mainz Pain Staging System (MPSS) score of pain chronification. They described a significantly poorer physical and mental health-related quality of life in the short form (SF-12) health survey, had significantly higher depression, anxiety and stress values (DASS) and a poorer habitual well-being in the Marburg questionnaire on habitual well-being (MFHW). Significant group differences had only small effect sizes. Even though most predictors for the inpatient treatment setting in multivariate analysis were significant, in total they explained less than 5% of the variance. The results indicate that pain therapy in specialized pain settings more and more has to manage patients with higher pain chronification, higher pain-related stress and previous therapy experience. The differences in patient characteristics between treatment settings are mostly clinically unimportant. Differences in clinical features do not declare the allocation to one treatment setting or the other.

Abstract
BACKGROUND More than 10 years ago Gerbershagen gave a pessimistic prognosis for treatment success in patients with higher stages of pain chronification. To date only few studies concerning this statement exist and the results are inconsistent. The objective of this study was to evaluate the prognostic validity of the Mainz pain staging system (MPSS) in a large multicenter sample. It was assessed whether effects of treatment in patients with higher stages of pain chronification are less than those in other patients. Of further interest was whether treatment success is related to different outcome measures. METHODS A total of 1,461 patients with the pain syndromes headache, neuropathic pain, back pain or algiomuscular pain and arthralgia were enrolled in the analysis. They were selected from the QUAST analysis sample which includes patients from 19 cooperating pain clinics. All patients had completed the German pain questionnaire prior to pain treatment and these data were compared with the last available questionnaire during the course of treatment. Outcome measures were pain intensity, psychological disability scores and patient global impression of success (PGIS). RESULTS Analysis showed a significant improvement of all outcome measures in every MPSS stage. The greatest improvement was noted for pain intensity whereas outcome variables regarding mental health revealed the lowest improvement. Compared with patients with low pain chronification, changes in pain intensity were smaller for patients with the highest MPSS stage III but even in these patients the strength of effect was more than 0.80. About 50% of all patients showed a reduction of pain intensity of 2 or more points on an 11 point numerical rating scale and 46.6% of patients with a MPSS stage III showed this improvement. Importantly, PGIS was independent of the stage of chronification. Nearly 45% of all patients evaluated the treatment success as good or very good. CONCLUSIONS According to the view of the patients, treatment in specialized pain centres is successful even in the highest stage of pain chronification. This notwithstanding, success of treatment must not be confounded with the efficacy of an intervention. It has to be noted that the results of the current study do not allow conclusions regarding efficacy of treatment.

Abstract
BACKGROUND Criterion-related validity of the Mainz Pain Staging System (MPSS) was examined. PATIENTS AND METHODS The effect of staging of pain on pain-related and psychosocial measures was investigated in a cross-sectional design among 478 patients with chronic low back pain in inpatient orthopedic rehabilitation (ICD-10 diagnoses: M45.4/M45.5, M54.4/M54.5). Pain-related measures were selected from the German Pain Questionnaire of the International Association for the Study of Pain (DGSS). The psychosocial measures depression (ADS), anxiety (HADS-D), somatization (SCL-90-R), quality of life (SF-12), functional capacity (FFbH-R), pain sensation (SES) as well as pain experience and strategies of coping with pain (FESV) were assessed. Furthermore, the frequency distribution of scores in the clinical range in pain-related and psychosocial measures depending on the staging of pain was examined. Finally, initial indications of the predictive validity of the MPSS were investigated among 116 inpatients. RESULTS Staging of pain had a significant impact both on levels of measures and proportion of clinically referred patients. Patients in stage III, but also those in stage II showed significantly impaired levels. Patients in stage III also showed more scores in the clinical range than expected in the lowest pain intensity, ADS depression, somatization of the SCL, functional capacity, and pain sensation. The MPSS before rehabilitation, together with mental health, seem to be a good predictor of depressive symptoms 6 months after rehabilitation. CONCLUSION The results support criterion validity of the MPSS, however, they also corroborate the concept that identification of medium and high grade pain by the MPSS has to be followed by a psychological diagnostic assessment. By this stepwise diagnostic process, therapy aims and treatment regimens can be designed more adequately.

Abstract
BACKGROUND The aim of this study was to investigate the criterion validity of the Mainz Pain Staging System (MPSS), considering the four axes of the MPSS separately. METHODS AND DESIGN Psychological and pain-related impairments were analysed depending on the stage of axis (I, II, III) for each single axis of the MPSS in a consecutive sample of 280 patients with chronic low back pain in orthopaedic inpatient rehabilitation. In addition, the distribution of frequency of clinically significant symptoms in depression, anxiety and somatisation were examined depending on the stage of axis. RESULTS For all axes, an increasing stage was associated with greater psychological and pain-related impairments. Particularly patients assigned to stage III on axis 1 (temporal aspects) and 2 (spatial aspects) and patients assigned to stage II on axis 3 (drug intake) and 4 (utilisation of the health care system) showed enhanced psychosocial impairments and more frequently had clinically relevant symptoms in psychological variables. CONCLUSION Findings confirm the criterion validity of the MPSS for chronic low back pain. In addition, results support the significance of psychosocial factors for the further development of chronicity.

Abstract
BACKGROUND Problems concerning the sustainability of medical rehabilitation are well known. Persistent avoidance behavior might be a potential cause. The present study is designed to determine the relationship between pain and pain-related behavior (resignation, distraction, avoidance) during the rehabilitation process. In addition, the impact of gender, age, level of chronicity, and location of ailments are investigated. METHODS Pain (German pain perception scale, SES) and pain-related behavior (German pain control questionnaire, FSR) were measured in 309 orthopedic rehabilitation patients. RESULTS Affective pain, resignation and distraction are more pronounced in women than in men. Participants with highly increased levels of chronicity have more affective and sensory pain and higher values of avoidance and resignation. During the rehabilitation process, there was a decrease in affective pain, sensory pain and resignation. The difference values correlate significantly. CONCLUSION Rehabilitation is effective for pain reduction. However, only limited changes in pain-related behavior were detected.

Abstract
Concepts for treating back pain by considering recent advancements in understanding chronic pain have been increasingly discussed over the last years. In general, any kind of therapy requires a most accurate diagnosis; however, in cases of lumbar back pain matching clinical observations with known structural pathologies is not always straight forward. Here, we suggest a concept of in-patient gradual diagnosis of patients with back pain that includes stepwise structural and functional components. We emphasize that in addition to the specific (classifiable) factors causing back pain (e.g. compression of lumbar nerve roots, facet joint associated pain syndrome, sacroiliacal dysfunction, segmental instability) also unspecific (non-classifiable) causes as well as disease-associated and/or determining bio-psychological or social factors need to be considered. With this study, we aim to introduce the procedure and assess the value of in-patient gradual diagnostics. We will describe different approaches, which we will evaluate for specific indications.
