Association between chronic low back pain and regular exercise, sedentary behaviour and mental health before and during COVID-19 pandemic: insights from a large-scale cross-sectional study in Germany.

BACKGROUND: Nonspecific chronic low back pain (CLBP) is a complex symptom with numerous possible causes and influencing factors. Understanding how modifiable factors affect the course of CLBP is important for preventing progression. As the COVID-19 pandemic has changed the lifestyle of many people, this study paper assessed whether it also changed the influence of modifiable lifestyle factors (regular exercise and sedentary behaviour) and mental health factors (anxiety and depression) on CLBP pain intensity and disability by comparing the strength of these associations before and during the pandemic. We hypothesised that the importance of regular physical activity and good mental health for CLBP patients would increase during the pandemic. METHODS: These questions were investigated in a cross-sectional study of insurance claims data and self-reported data from various questionnaires from 3,478 participants in a German CLBP health intervention (2014-2021) by calculating pre- and intra-pandemic odds ratios (OR) and 95% confidence intervals (CI) for each variable of interest and outcome. Potential confounders were also considered. Pandemic status was treated as an effect modifier. Based on the date of enrolment, participants were classified as "pre-pandemic" or "pandemic". RESULTS: Regularly exercising ≥ 4 h/week significantly reduced the odds of high disability for men (OR 0.49, 95% CI 0.31 - 0.79, p = 0.003) and women (OR 0.30, 95% CI 0.14 - 0.563, p = 0.002) and reduced the probability of severe pain in women (OR 0.37, 95% CI 0.21 - 0.65, p < 0.001). Each one-point increase in PHQ-4 score for anxiety and depression increased the OR of high pain intensity by 1.25 points (95% CI 1.18 - 1.34, p < 0.001). A clear impact of COVID-19 lockdowns was observed. In individuals who exercised ≥ 4 h/week the OR of high disability was 0.57 (95% CI 0.36 - 0.92, p = 0.021) in the pre-pandemic group compared to 0.29 (95% CI 0.12 - 0.56, p = 0.002) in the pandemic group. The probability of high disability increased from an OR of 1.42 (95% CI 1.33 - 1.52, p < 0.001) per marginal increase in the PHQ-4 scale before the pandemic, to an OR of 1.73 (95% CI 1.58 - 1.89, p < 0.001) during the pandemic. CONCLUSIONS: The magnitude of association of the factors that influenced high pain intensity and disability increased during the pandemic. On the one hand, the protective effect of regular exercising was greater in participants surveyed during lockdown. On the other hand, a higher risk through anxiety or depression during the lockdown was identified. An additional study with objective measures of sedentary behaviour and physical activity is needed to validate these results. More in-depth investigation of lockdown-induced associations between reduced daily physical activity, increased levels of anxiety and depression, and their effects on CLPB could also be worthwhile. TRIAL REGISTRATION: This study used routinely collected data from a CLBP intervention that was previously evaluated and registered in the German Registry of Clinical Trials under DRKS00015463 (04/09/2018). The original ethics approval, informed consent and self-reported questionnaire have remained unchanged and are still valid.

Cost-effectiveness analysis of a chronic back pain multidisciplinary biopsychosocial rehabilitation (MBR) compared to standard care for privately insured in Germany.

BACKGROUND: Multidisciplinary biopsychosocial rehabilitation (MBR) is highly recommended for chronic lower back pain (CLBP) treatment, but its economic benefit remains to be clearly demonstrated. The purpose of this study is to analyse the effect of a 12-month MBR programme of behavioural change coaching and device-supported exercise on direct medical costs, sick leave and health-related quality of life (HRQOL) at 24 months. METHODS: An incremental cost-effectiveness analysis was conducted in Germany from a private health insurance perspective using data from a multi-centre, two-arm randomised controlled trial with parallel-group Zelen's randomisation and 24-month follow-up. After removing dissimilarities in characteristics between MBR and usual care (control) via propensity score matching, treatment effects were calculated using a difference-in-difference approach. RESULTS: Base-case analysis of the MBR (n=112) and usual care group (n=111) showed an incremental cost-effectiveness ratio (ICER) of €8,296 per quality-adjusted life year (QALY) gained, indicating that the intervention was cost-effective. Compared to the controls, MBR reduced economically unaccounted sick leave due to back pain in the last six months by 17.5 days (p = 0.001) and had a positive effect on health-related quality of life (HRQOL) (0.046, p=0.026). Subgroup analysis of participants with major impairment demonstrated that a dominant intervention was possible, as reflected by an ICER of - €7,302 per QALY. Savings were driven by a - €1,824 reduction in back pain-specific costs. Moreover, sick leave was 27 days (p = 0.006) less in the MBR group. CONCLUSIONS: This first cost-effectiveness study with combined data from a private health insurer and a controlled trial in Germany demonstrated that long term MBR for the treatment of CLBP is cost-effective. Subgroups with major impairment from back pain benefitted more from the intervention than those with minor impairment. MBR significantly reduced sick leave in all participants. Hence, it is a profitable intervention from a societal point of view. TRIAL REGISTRATION: The trial of the evaluation study was retrospectively registered in the German Clinical Trials Register under trial number DRKS00015463 retrospectively (dated 4 Sept 2018).

[Evaluation of outpatient medical pain management in Germany : Results of an internet-based cross-sectional survey among pain specialists in outpatient departments]. / Bewertung der ambulanten ärztlichen Schmerztherapie in Deutschland : Ergebnisse einer internetbasierten Querschnittsbefragung unter ambulant tätigen Schmerzmedizinern.

BACKGROUND: On 31 December 2016, a total of 1206 physicians participated in the outpatient care of chronic pain patients according to the criteria of a special pain management program (QSV). Because of the largely existing shortage of treatment resources for chronic pain patients, there is a lack of data regarding the evaluation of outpatient pain management by highly specialized pain therapists. METHODS: In a hybrid Delphi procedure, a questionnaire concerning the content, structural and personal assessment of outpatient pain management in Germany was developed. With the help of this instrument, an internet-based cross-sectional survey of 281 QSV pain therapists from four German states (Berlin, Lower Saxony, Saxony, Baden-Württemberg) and of all the heads of university outpatient pain services (n = 36) in Germany was conducted. RESULTS: The adjusted response rate of the survey was 35.9%. The response rate of the heads of university outpatient pain services was 66.7%. In 91% of the respondents the proportion of chronic pain patients in the medical practices was more than 70%. Whereas 67.3% were satisfied with the situation in their medical practice, 63.4% were dissatisfied with the current organizational structure of the pain management in Germany. They expressed their dissatisfaction especially in terms of budgeting regulations (69.3%), the cooperation with psychotherapists (69.3%) and interdisciplinary networking (50.5%). The 1­year specialist training in pain management (87.1%) and the completion of a psychosomatic basic care course (90.1%) were assessed as a good preparation for the later profession. A multitude of free comments indicated that the pain specialist training is too short and insufficient. Most of the respondents considered the establishment of a specialist board certification for pain management more suitable from the perspective of physicians (61.4%) and the patients (54.5%). Of the heads of university outpatient pain services 70.8% expressed the wish for autonomous structures with separate budgets and 75.0% indicated that under the current conditions their outpatient pain services are not working profitably. Only 39.7% of the QSV pain therapists provided fellowship training for physicians and 57.6% were planning to retire during the next 10 years. CONCLUSION: Highly specialized pain therapists are dissatisfied because of the lack of independence of the organizational structure of pain management care and the insufficient interdisciplinary network in outpatient pain management. A possible solution for a better pain management care and the recruitment problems may be the establishment of a board certification for pain management.

[Anonymize or personalize? : Does social desirability influence the response behavior of chronic pain patients?] / Anonymisieren oder personalisieren? : Beeinflusst die soziale Erwünschtheit das Antwortverhalten von chronischen Schmerzpatienten?

BACKGROUND: The subjective state of health with respect to pain and psyche was surveyed utilizing validated pain questionnaires in patients undergoing special pain therapy and represents the basis for targeted treatment measures. OBJECTIVE: The purpose of this study was to investigate the possible distortion of answers due to social desirability of responses in chronic pain patients. MATERIAL AND METHODS: During two survey periods assessing patient satisfaction using both anonymized and personalized questionnaires, the effects arising from socially desirable response patterns were analyzed. The sample consisted of chronic pain patients being treated in an inpatient therapy setting. RESULTS: In both periods of observation no significant impact on the response behavior of chronic pain patients was found in personalized or anonymized questionnaires. CONCLUSION: The results of the study suggest that the responses of chronic pain patients with respect to their subjective state of health are not influenced by social desirability. Thus, scoring systems such as the German pain questionnaire will not be influenced by social desirability in chronic pain patients and can therefore be used as a part of diagnostics and therapy planning.

[Intersectoral pain treatment. The Algesiologikum group]. / Sektorübergreifende schmerzmedizinische Versorgung. Der Algesiologikum-Verbund.

Cross-sectoral clinical pathways for chronic pain patients in standard and routine care are a major challenge for the German healthcare system. The Algesiologikum group has developed such clinical pathways including an essential infrastructure. Cooperation partners of the Algesiologikum group are two outpatient medical care units, one neurosurgery practice and four hospitals. In the outpatient sector as well as in the inpatient sector the Algesiologikum group provides a multidisciplinary team caring for chronic pain patients. The range of treatment in the hospitals includes multimodal, invasive and surgical pain therapy. The present report illustrates possibilities and frontiers of the Algesiologikum concept based on all patients treated since 2009.

A cross-sectional study to validate an administrative back pain severity classification tool based on the graded chronic pain scale.

Treatment of chronic lower back pain (CLBP) should be stratified for best medical and economic outcome. To improve the targeting of potential participants for exclusive therapy offers from payers, Freytag et al. developed a tool to classify back pain chronicity classes (CC) based on claim data. The aim of this study was to evaluate the criterion validity of the model. Administrative claim data and self-reported patient information from 3,506 participants (2014-2021) in a private health insurance health management programme in Germany were used to validate the tool. Sensitivity, specificity, and Matthews' correlation coefficient (MCC) were calculated comparing the prediction with actual grades based on von Korff's graded chronic pain scale (GCPS). The secondary outcome was an updated view on direct health care costs (€) of patients with back pain (BP) grouped by GCPS. Results showed a fair correlation between predicted CC and actual GCPS grades. A total of 69.7% of all cases were correctly classified. Sensitivity and specificity rates of 54.6 and 76.4% underlined precision. Correlation between CC and GCPS with an MCC of 0.304 also indicated a fair relationship between prediction and observation. Cost data could be clearly grouped by GCPS: the higher the grade, the higher the costs and the use of health care. This was the first study to compare the predicted severity of BP using claim data with the actual severity of BP by GCPS. Based on the results, the usage of CC as a single tool to determine who receives CLBP treatment cannot be recommended. CC is a good tool to segment candidates for specific types of intervention in BP. However, it cannot replace a medical screening at the beginning of an intervention, as the rate of false negatives is too high. Trial registration The study was conducted using routinely collected data from an intervention, which was previously evaluated and registered retrospectively in the German Registry of Clinical Trials under DRKS00015463 (04/09/2018). Informed consent and the self-reported questionnaire have remained unchanged since the study and, therefore, are still valid according to the ethics proposal.

[Are American physicians more satisfied?--results from an International Study of Physicians in University Hospitals]. / Sind amerikanische Arzte zufriedener?--Ergebnisse einer internationalen Studie unter Arzten an Universitätskliniken.

Understanding the factors that affect physicians' job satisfaction is important not only to physicians themselves, but also to patients, health system managers, and policy makers. Physicians represent the crucial resource in health-care delivery. In order to enhance efficiency and quality in health care, it is indispensable to analyse and consider the motivators of physicians. Physician job satisfaction has significant effects on productivity, the quality of care, and the supply of physicians. The purpose of our study was to assess the associations between work-related monetary and non-monetary factors and physicians' work satisfaction as perceived by similar groups of physicians practicing at academic medical centres in Germany and the U.S.A., two countries that, in spite of differing health-care systems, simultaneously experience problems in maintaining their physician workforce. We used descriptive statistics, factor and correlation analyses to evaluate physicians' responses to a self-administered questionnaire. Our study revealed that overall German physicians were less satisfied than U.S. physicians. With respect to particular work-related predictors of job satisfaction we found that similar factors contributed to job satisfaction in both countries. To improve physicians' satisfaction with working conditions, our results call for the implementation of policies that reduce the time burden on physicians to allow more time for interaction with patients and colleagues, increase monetary incentives, and enhance physicians' participation in the development of care management processes and in managerial decisions that affect patient care.

'Manacled competition': market reforms in German health care.

In 1993 Germany joined the small but swelling ranks of societies determined to explore managed competition as a means of slowing the growth of health spending by giving stakeholders new incentives for efficiency. Realizing the benefits of competition, however, demands changes in institutional norms and regulatory practices that now largely handcuff those who would follow competitive logic into "managed care." In time Germany's system of "manacled competition" may evolve into a happy higher synthesis of managed care and managed competition. Or policymakers may conclude that the political price of installing workable market forces in health care is too high and reconcile themselves to more traditional applications of political pressure.

[Health care system facing change: physician networks: driving force for integrated care?]. / Gesundheitssystem im Umbruch : Ärztenetze: Treiber für integrierte Versorgung?

The German health care system is faced with enormous challenges: population ageing, more chronic diseases and multimorbidity. The fragmentation of medical care into disconnected parts-ambulant and clinical services, pharmaceutical provision, nursing care etc.-is inefficient and inhibits coordinated courses of treatment. Instead of this new types of organizational structures and processes are needed. By means of different health care acts the German government has supported innovative medical care structures for many years. In the meantime, 30,000 doctors have joined 400 physician networks. Their aims are to improve the coordination of services, to facilitate collaboration among providers and to ensure better health care to the population. Furthermore, those interdisciplinary networks are crucial prerequisites for integrated health care. But there is still a lot of work to do. The successful integration of the components of health care into functioning process chains depends on political, economic and sociocultural parameters.

Hospital stay frequency and duration of patients with advanced cancer diseases - differences between the most frequent tumour diagnoses: a secondary data analysis.

The differences in the number and duration of hospital stays of cancer patients in an advanced stage of disease were to be examined with regard to the most frequent cancer diagnoses. Therefore, routinely compiled data of the largest health insurance company in the State of Lower Saxony, Germany, were analysed. Patients with lung, colon, breast and prostate cancer were included, who died in the year of 2004. The parameters of frequency (case numbers) and duration (days) of inpatient hospital stays were examined for the 5-year period of 2000-2004, with special focus on the years 2003/2004. 355 patients were included. On average, the number of inpatient hospital stays amounted to 2.7 cases and 29 days per patient. 87.5% of the hospital stays within the study period occurred in 2003/2004. The patient groups differed significantly both in the average number of cases and in the duration of hospital stays (Kruskal-Wallis test: P<0001), whereby patients with lung cancer underwent inpatient hospital treatment most frequently (3.3 times), and for the longest periods (35 days). This study shows that patients in an advanced stage of lung cancer are a particular important target group for reducing hospitalization at the end of life. They should receive special attention when structures of palliative care are extended.

[Concepts for a demand-oriented structuring of palliative care in the German Health Care System: the example of Lower Saxony]. / Konzepte zur bedarfsgerechten Strukturierung der Palliativversorgung im deutschen Gesundheitswesen: Das Beispiel des Bundeslandes Niedersachsen.

Palliative care can be considered a holistic care approach for patients faced with incurable and progressive diseases in their last period of life. In this context, structural, cultural and content-related deficits are increasingly taken into account in the German health care system, however, there is a lack of scientific data. Therefore, it was the objective of an expert team at Hannover Medical School to analyse the current situation of palliative care in Lower Saxony from the perspective of health system research and to give recommendations for its further development, based on empirical studies in Lower Saxony and on a systematic national and international literature review. The study revealed that the main shortcomings were an unclear structuring and an inadequate definition with respect to other areas of care, a fundamental lack of integration in regard of routine processes of care and a lack of thorough tools for needs assessments. Therefore, a concept for the integration of palliative care in the care processes of cancer patients was developed and the specific need for hospice beds in regional districts was calculated by using parameters representing provision-related and epidemiological/demographic conditions. In comparison to current structures, an assessment of over- and undersupply as well as specific recommendations how to optimize palliative care were provided for politicians, payers and providers in Lower Saxony.

[Integrated delivery systems in California--success and failure determining factors for the first 10 years and impetus for Germany]. / Integrierte Versorgungssysteme in Kalifornien - Erfolgs- und Misserfolgsfaktoren der ersten 10 Jahre und Impulse für Deutschland.

Since the coming into effect of the Health Care Modernization Act (Gesundheitsmodernisierungsgesetz) the conditions for integrated health care delivery are favourable in Germany. However, comprehensive approaches are a long time in coming. In contrast, integrated health care delivery as an integral part of the spreading of managed care entered a further stage of development, which enables health care decision makers to draw conclusions regarding the further development of integrated health care delivery in Germany. Based on case studies integrated delivery systems in the San Francisco Bay Area have been analyzed with the objective to evaluate pitfalls and successful strategies for integrated health care delivery. The major pitfalls refer to an insufficient local focus, a lack of actual integration and the application of per capita reimbursement (which is a key subject on the political agenda in Germany as well) within integrated delivery systems. On the contrary, successful strategies include achieving a dynamic tension between centralized and decentralized coordination, internal and external relationship management, well organised human resource management including a well-defined corporate policy and a comprehensive implementation of information technology. Based on US experiences with integrated delivery systems implications for the design of integrated health care delivery in Germany are discussed.
