RESUMO
BACKGROUND: A different utilization of health care services due to socioeconomic status on the same health plan contradicts the principle of equal treatment. We investigated the presence and magnitude of socioeconomic differences in utilization of diagnostic imaging and non-pharmaceutical conservative therapies for patients with spinal diseases. METHODS: The cohort study based on routine healthcare data from Germany with 11.7 million patient-years between 2012 and 2016 for patients with physician-confirmed spinal diseases (ICD-10: M40-M54), occupation and age 20 to 64 years. A Poisson model estimated the effects of the socioeconomic status (school education, professional education and occupational position) for the risk ratio of receiving diagnostic imaging (radiography, computed tomography, magnetic resonance imaging) and non-pharmaceutical conservative therapies (physical therapy including exercise therapy, manual therapy and massage, spinal manipulative therapy, acupuncture). RESULTS: Patients received diagnostic imaging in 26%, physical therapy in 32%, spinal manipulative therapy in 25%, and acupuncture in 4% of all patient-years. Similar to previous survey-based studies higher rates of utilization were associated with higher socioeconomic status. These differences were most pronounced for manual therapy, exercise therapy, and magnetic resonance imaging. CONCLUSIONS: The observed differences in health care utilization were highly related to socioeconomic status. Socioeconomic differences were higher for more expensive health services. Further research is necessary to identify barriers to equitable access to health services and to take appropriate action to decrease existing social disparities.

BACKGROUND: Rising surgery rates have raised questions about the indications for spinal surgery. The study investigated patient-level and regional factors associated with spinal surgery for patients with spinal diseases. METHODS: We undertook a cohort study based on routine healthcare data from Germany of 18.4 million patients within 60.9 million episodes of two patient-years before a possible spinal surgery in the time period 2008 to 2016. Using a Poisson model, the effects of a broad range of patient-related (sociodemographic, morbidity, social status), disease- and healthcare-related (physicians' specialty, conservative treatments) and regional variables were analyzed. RESULTS: There was substantial regional heterogeneity in the occurrence of spinal surgery which decreased by only one quarter when controlling for the various determinants assessed. Previous musculoskeletal and mental health disorders as well as physical therapy were associated with a lower probability of surgery in the fully-adjusted model. Prescriptions for pain medication and consultations of specialists were associated with a higher probability of surgery. However, the specific severity of the vertebral diseases could not be taken into account in the analysis. Furthermore, a substantial proportion of patients with surgery did not receive a consultation with an outpatient specialist (29.5%), preoperative diagnostics (37.0%) or physical therapy (48.3%) before hospital admission. CONCLUSION: This large study on spinal diseases in Germany highlights important patterns in medical care of spinal diseases and their association with the probability of spinal surgery. However, only a relatively small proportion of the regional heterogeneity in spinal surgery could be explained by the extensive consideration of confounders, which suggests the relevance of other unmeasured factors like physicians' preferences.

BACKGROUND: There are different procedures for both, the diagnosis and the therapy of a periprosthetic joint infection (PJI), however, national or international guidelines for a standardised treatment regime are still lacking. The present paper evaluates the use of the predominant treatment protocols for PJI in certified total joint replacement centres (EPZ) in Germany based on an EndoCert questionnaire. MATERIALS AND METHODS: The questionnaire was developed in cooperation with the EndoCert Certification Commission to survey the treatment protocols for septic revision arthroplasties in EPZ. Questions targeted the various treatment options including prosthesis preserving procedures (DAIR - Debridement, antibiotics, irrigation, and retention of the prosthesis), one-stage revision, two-stage revision, removal of the endoprosthesis and diagnostic sampling prior to re-implantation. All certified EPZ participated (n = 504) and the results from the current survey in 2020 were compared to data from a previous analysis in 2015. RESULTS: The number of centres that performed DAIR up to a maximum of 4 weeks and more than 10 weeks after index surgery decreased since 2015, while the number of centres that provided a one-stage revision as a treatment option increased (hip: + 6.3%; knee: + 6.6%). The majority of the centres (73.2%) indicated a 4-8 week period as the preferred interval between prosthesis removal and re-implantation in two-stage revision in hip as well as knee revisions. Centres with a higher number of revision surgeries (> 200 revisions/year), opted even more often for the 4-8 week period (92.3%). In two-stage revision the use of metal-based spacers with/without reinforcement with antibiotic-containing cement as an interim placeholder was significantly reduced in 2020 compared to 2015. There was also a clear preference for cemented anchoring in two-stage revision arthroplasty in the knee in 2020, whereas the majority of hip replacements was cementless. Additionally, in 2020 the number of samples for microbiological testing during the removal of the infected endoprosthesis increased and 72% of the centres took five or more samples. Overall, the number of EPZ with a standardised protocol for the procedure expanded from 2015 to 2020. CONCLUSION: While there was a trend towards standardised therapeutic algorithms for PJI with more uniform choices among the centres in 2020 compared to 2015, the treatment often remains an individual decision. However, since a consistent treatment regime is of vital importance with an expected rise of total numbers of revision arthroplasties, uniform definitions with regard to comparability and standardisation are necessary for the further development of the EndoCert system.

BACKGROUND: Total knee replacement requires follow-up treatment. This can take place on an outpatient basis as part of health insurance coverage, but also as outpatient or inpatient rehabilitation. KIND OF REHABILITATION: Outpatient rehabilitation provides comparable results to inpatient rehabilitation, but only for those patients who are suitable for outpatient rehabilitation. Inpatient rehabilitation should be indicated depending on general health status, general physical fitness, housing situation, accessibility of rehabilitation facilities and possibilities of social support in the home environment, as well as age and comorbidities. Physiotherapeutic procedures should focus on exercise therapy. Passive reactive measures complement the therapy. For patients of working age, the activity profile should be considered as part of the rehabilitation process. Patient education, with information on prosthesis-appropriate behavior, represents an important component in follow-up treatment. PROSPECT: Demographic change requires increasing consideration of orthogeriatric aspects. Fast-track programs will not make follow-up treatment superfluous, but with accelerated processes they represent a new challenge for sectoral cooperation.

Severely injured patients need a qualified and seamless rehabilitation after the end of the acute treatment. This post-acute rehabilitation (phase C) places high demands on the rehabilitation facility in terms of personnel, material, organizational and spatial requirements.The working group on trauma rehabilitation of the German Society for Orthopedics and Traumatology e.â¯V. (DGOU) and other experts have agreed on requirements for post-acute phase C rehabilitation for seriously injured people. These concern both the personnel and material requirements for a highly specialized orthopedic trauma surgery trauma rehabilitation as well as the demands on processes, organization and quality assurance.A seamless transition to the follow-up and further treatment of seriously injured people in the TraumaNetzwerk DGU® is ensured through a high level of qualification and the corresponding infrastructure of supraregional trauma rehabilitation centers. This also places new demands on the TraumaZentren DGU®. Only if these are met can the treatment and rehabilitation of seriously injured people be optimized.

BACKGROUND: The periprosthetic joint infection (PJI) is a severe complication in the field of arthroplasty. Despite the rising number of primary joint replacements, no unified therapeutic standard has been established for the treatment of PJI yet. METHODS: A survey on the principles of treatment of PJI in Germany was conducted. A total of 515 EndoProthetikZentren (EPZ) were included, resulting in a response rate of 100%. RESULTS: For early infections 97.6% of the centers use prosthesis-preserving procedures (DAIR). A one-stage exchange was implemented by less than 50% of the centers. If implemented, this treatment entails a prior selection of patients for a successful treatment. The two-stage exchange is performed in all centers, and most centers proceed with the implantation of a cemented spacer between stages. 75% of the centers proceed with a center-based concept for the treatment of PJI. CONCLUSION: The aim of a uniform PJI standard at the centers has not yet been fully achieved. Further improvements within the certification were initiated. The most relevant treatment options in Germany are displayed. The two-stage revision with a cemented spacer is the most widely implemented treatment. This exposition of principles could help for the further development of standardized treatment guidelines and definitions.

There is an ongoing discussion about demographic change, a possible lack of young doctors and its impact on the healthcare system in Germany. Up to now, no valid data has been available on the exact numbers of residents in orthopedics and trauma surgery. Therefore, the aim of this study was to determine the actual number of residents in Germany in 2013/2014. We generated a database with all eligible providers of postgraduate training in orthopedics and trauma surgery in Germany. All of these were asked to fill out a questionnaire about the number of trainees, their gender and year of training. We achieved an 80% response rate (1509 questionnaires). Within these institutions, 4310 residents are trained. For Germany, this means an estimated number of about 5300 residents in the year 2013/2014. Ninety percent of postgraduate training is performed within a hospital and one-third of the residents are female. Looking at the expected number of doctors who will retire within the next five years, there seems to be enough young doctors to fill the gap. However, by 2040, an increased demand for othopedic and trauma surgeons is experted. Thus, we recommend centrally analyzing and coordinating the demand of residents in orthopedics and trauma surgery in Germany.

There has been a growing shortage of physicians in Germany in recent years. In this study, we analyse the situation facing orthopaedic hospitals and trauma centres.Between 22 November and 5 December 2022, a web-based questionnaire was sent out by the Academy of the German Trauma Society (AUC) and by the Society of Leading Orthopaedic and Trauma Surgeons (VLOU).The questionnaire was answered by 185 heads of department. Of the responses, 20% came from university hospitals or major trauma centres, and a third from regional or local clinics. More than half of the hospital departments (55%) had a median of 2.7 vacant doctor positions. Among those hospitals, 47% had a vacant position for a consultant, 33% for a board-certified specialist, and 89% for a junior doctor. Within the university hospitals, only one third had vacant doctor positions. The responding heads of department gave negative feedback regarding the number of applications, the qualifications of young doctors, and their motivation for scientific work (in university hospitals).More than half of the responding hospitals had vacant doctor positions. If we are to counteract the growing shortage of doctors in orthopaedics and trauma surgery, the number of clinical doctors in general and the working conditions in hospitals have to be improved. Teaching hospitals should try to improve the training of medical students with a view to inspiring greater motivation to work in orthopaedics and trauma surgery.

To improve arthroplasty care quality, the EndoCert initiative focuses on structural, processual, and surgeon-related quality assurance. The aim of this study was to assess the impact of a surgeon's case load in certified centers on quality of care, distinguished by different types of surgeons. Data from the annual reports of EndoCert certified centers for the years 2017 to 2021 were analyzed. The study revealed reduced numbers of cases, while the number of surgeons remained constant. Since 2020, the decrease in the average case load per surgeons has become more pronounced. There were also differences between senior (sECrs) and EndoCert-registered surgeons (ECrs). Before the 2020 pandemic, over half of surgeons exceeded minimum annual case requirements, while, afterwards, this number declined, especially for the ECrs. Affiliated surgeons, who are also sECrs or ECrs, performed predominantly lower numbers of arthroplasties. However, a higher percentage of affiliated surgeons in a center correlated with faster surgeries and lower mortality rates. High numbers of arthroplasties per center or surgeon were not necessarily associated with better quality indicators, especially in the knee. While the comprehensive quality standards may offset volume effects, EndoCert should reconsider minimum volume regulations based on surgeon, but also on each joint.
RESUMO
Knee arthroplasty is one of the most frequently performed operations in Germany, with approximately 170000 procedures per year. It is therefore essential that physicians should adhere to an appropriate, and patient-centered indication process. The updated guideline indication criteria for knee arthroplasty (EKIT-Knee) contain recommendations, which are based on current evidence and agreed upon by a broad consensus panel. For practical use, the checklist has also been updated.For this guideline update, a systematic literature research was conducted in order to analyse (inter-)national guidelines and systematic reviews focusing on osteoarthritis of the knee and knee arthroplasty, to answer clinically relevant questions on diagnostic, predictors of outcome, risk factors and contraindications.Knee arthroplasty should solely be performed in patients with radiologically proven moderate or severe osteoarthritis of the knee (Kellgren-Lawrence grade 3 or 4), after previous non-surgical treatment for at least three months, in patients with high subjective burden with regard to knee-related complaints and after exclusion of possible contraindications (infection, comorbidities, BMI ≥ 40 kg/m2). Modifiable risk factors (such as smoking, diabetes mellitus, anaemia) should be addressed and optimised in advance. After meeting current guideline indications, a shared decision-making process between patients and surgeons is recommended, in order to maintain high quality surgical management of patients with osteoarthritis of the knee.The update of the S2k-guideline was expanded to include unicondylar knee arthroplasty, the preoperative optimisation of modifiable risk factors was added and the main indication criteria were specified.
RESUMO
BACKGROUND: The measures taken in the coronavirus disease pandemic have had major structural and financial effects on orthopaedics and trauma surgery as many surgeries in this field. Experience Appropriate reports from non-surgical orthopaedics are not yet available. AIMS OF THE STUDY: The study aimed to provide information on the changes that occurred in a group of patients with spinal diseases undergoing conservative in-patient treatment during the coronavirus disease pandemic, with regard to the number of cases, patient structure and course of treatment. MATERIALS AND METHODS: Data from a total of 954 patients from an acute department for conservative treatment of back pain from the years 2019 and 2020 were retrospectively compared, thus allowing conclusions to be drawn about the course of in-patient conservative spinal treatment. In addition to sociodemographic data, numerical pain rating scales, scales for impairment by pain and physical function at the beginning and at the end of treatment were analysed using descriptive statistics and differentiation tests. RESULTS: The study showed a 21% reduction in the number of cases in 2020 compared with those in 2019. The patient structure has changed in terms of diagnosis groups and physical function. The values of the assessments on discharge and their pre-post differences show an almost identical pattern of treatment outcomes before and after the start of the pandemic. CONCLUSIONS: The relatively small decline in the number of in-patient admissions for the non-surgical treatment of specific spinal disorders indicates that this treatment option was also necessary in the pandemic-related crisis. With minor changes in the patient structure, comparable treatment results could be achieved.

BACKGROUND: The EndoCert initiative does not yet allow a long-term assessment of outcome quality. The assessment cannot be achieved without cooperation with the German arthroplasty registry (EPRD) and other quality assurance infrastructure, such as the quality assurance system of the nationwide healthcare insurance data for inpatient hospital treatment (QSR) by the German local healthcare fund (AOK). Therefore, the quality of care of all certified centres for joint replacement (EPZ) after primary hip and knee arthroplasty was to be examined for the first time. These data were subsequently compared to the data of the EPRD. MATERIALS AND METHODS: In EPZ that provided care to at least one AOK-insured patient in 2016, the risk-adjusted 3year revision rate and the SMR-value (standardised mortality or morbidity ratio), which is the quotient of the observed and expected revision rate, were analysed as markers for the quality of care. Annual hospital volume, type of centre and audit results were examined as possible influencing factors. RESULTS: In the group comparison, significant differences (pâ¯= 0.042) for the SMR value of the 3year revision rate were demonstrated for hip arthroplasty with regard to the EPZ type. The annual number of primary hip arthroplasties, however, did not influence the 3year revision rate. For knee arthroplasties, no effect of the defined categories on the 3year revision rate and its SMR value was observed. The comparison of our 3year revision rates with those of the EPRD showed similar results for the hip but indicated significant differences for the knee. CONCLUSION: We did not observe a correlation between quality of care and annual hospital volume in certified EPZ. However, different quality assurance procedures can lead to different results with respect to the outcome quality. Therefore, a considerably improved interaction of the German quality systems must be achieved. Participation in the EPRD is not sufficient for this. Rather, a complete report of all arthroplasties must be required, at least with the achievement of a minimum reporting rate per participating hospital. Uniform inclusion and exclusion criteria should be defined.

Introduction: Aquatic or water-based exercise is a very popular type of exercise in particular for people with physical limitations, joint problems and fear of falling. The present systematic review and meta-analysis aimed to provide evidence for the effect of aquatic exercise on Bone Mineral Density (BMD) in adults. Methods: A systematic literature search of five electronic databases (PubMed/MEDLINE, Cochrane Library, Scopus, Web of Science and CINAHL) according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was conducted until 2022/01/30, with an update to 2022/10/07. We included controlled trials with a duration of more than 6 months and at least two study groups, aquatic exercise (EG) versus non-training controls (CG) with no language restrictions. Outcome measures were standardized mean differences (SMD) with 95%-confidence intervals (95%-CI) for BMD changes at the lumbar spine (LS) and femoral neck (FN). We applied a random-effects meta-analysis and used the inverse heterogeneity (IVhet) model to analyze the data. Results: Excluding an outlier study with an exceptionally high effect size for LS-BMD, we observed a statistically significant (p = .002) effect (EG vs. CG) of aquatic exercise for the LS-BMD (n = 10; SMD: 0.30; 95%-CI: 0.11-0.49). In parallel, the effect of aquatic exercise on FN-BMD was statistically significant (p = .034) compared to the CG (n = 10; SMD: 0.76, 95%-CI: 0.06-1.46). Of importance, heterogeneity between the trial results was negligible for LS (I2: 7%) but substantial for FN-BMD (I2: 87%). Evidence for risks of small study/publication bias was low for LS-BMD and considerable for FN-BMD. Discussion: In summary, the present systematic review and meta-analysis provides further evidence for the favorable effect of exercise on bone health in adults. Due to its safety and attractiveness, we particularly recommend water-based exercise for people unable, afraid or unmotivated to conduct intense land-based exercise programs.
RESUMO
BACKGROUND: Pain intensity is frequently measured on the 11-point numerical pain rating scale (NRS-PI), ranging from 0 (no pain) to 10 points (worst imaginable pain). However, it is difficult to interpret the clinical importance of changes from baseline to endpoint on this instrument. OBJECTIVES: To estimate the minimal detectable change (MDC) and the minimal clinically important difference (MCID) for average pain intensity in patients with specific back pain. MATERIALS AND METHODS: Data on 1232 subjects with specific back pain from a German hospital were included in this study. A score combining the patient's (PGIC) and the physician's global impression of change (CGIC) over the in-patient length of stay was used as an external criterion. A priori, we considered the score value "slightly improved" as the MCID. MDC was calculated using the standard error of measurement (SEM) and the standard deviation (SD) of the sample. MCID was estimated by the mean value of PI-NRS change in patients who self-assess as "slightly improved", and by sensitivity/specificity analyses, computed by the receiver operating characteristic method (ROC). RESULTS: MDC was 1.77. The MCS and ROC methods consistently showed an MCID of 2 for the total sample. Both methods showed the dependence of the MCID on the initial pain: 1 for mild to moderate pain at baseline (1â-â4 NRS points), 2 for moderate to severe pain (5â-â7) and 3â-â4 for very severe to extreme pain (8â-â10). For patients with lumbosacral intervertebral disc disorders and patients in the acute phase (duration of pain < 6 weeks), the ROC method resulted in a higher limit than the MCS method. CONCLUSIONS: In order to facilitate the interpretation of changes and to take into account the patient's perspective, the global assessment of the success of treatment should be used as an anchor criterion. In addition to dealing with pain measurement, function-related and psychosocial aspects of pain symptoms should be kept in mind.

The purpose of this systematic review and meta-analysis (PROSPERO ID: CRD42021250467) was to evaluate the effects of exercise on low-trauma overall and major osteoporotic fractures (hip, spine, forearm, or humerus fractures) and to determine the corresponding effect of supervision of the exercise program. Our systematic search of six literature databases according to the PRISMA guideline was conducted from January 1, 2013 (ie, date of our last search) to May 22, 2021, and included controlled clinical exercise trials with (i) individuals aged ≥45 years, (ii) cohorts without therapies/diseases related to fractures, (iii) observation periods of ≥3 months, and (iv) the number of low-trauma fractures listed separately for the exercise (EG) and control (CG) groups. We included 20 intervention studies with 21 EGs and 20 CGs comprising a pooled number of participant-years of n = 11.836 in the EG and n = 11.275 in the CG. The mixed-effects conditional Poisson regression revealed significant effects of exercise on low-trauma overall incidence (rate) ratio (IR 0.67, 95% confidence interval [95% CI] 0.51-0.87) and major osteoporotic fractures IR (0.69, 95% CI 0.52-0.92). Heterogeneity between the trials was moderate for low-trauma overall (I2 = 40%) and negligible (I2 < 1%) for major osteoporotic fractures. Supervision of the exercise program plays a significant role in the reductions of overall and major osteoporotic fractures with IR about twice as favorable in the predominately supervised (IR 0.44; 95% CI 0.27-0.73 and 0.38; 0.19-0.76) versus the predominately non-supervised exercise trials (IR 0.83; 95% CI 0.60-1.14 and 0.82; 0.64-1.05). In summary, the present study provides evidence for the positive effect of exercise on low-trauma overall and major osteoporotic fractures in middle aged to older adults. Supervision of the exercise program is a crucial aspect in exercise programs on fracture reduction. Thus, home-based exercise protocols should increasingly implement online classes to ensure widely consistent supervision and monitoring of the exercise program. © 2022 The Authors.

Exercise frequency is a key aspect of exercise protocols. In this systematic review and meta-analysis, we determined the effect of training frequency on (areal) bone mineral density (BMD) at lumbar spine (LS) and hip. Reviewing seven electronic databases up to April 2021, we conducted a systematic review of the literature according to the PRISMA statement. Inclusion criteria were (a) controlled exercise trials (b) with at least two study arms that compared low versus high exercise frequency, (c) an intervention ≥6 months and (d) BMD assessments at lumbar spine (LS) or hip. The analysis was conducted as a mixed-effect meta-analysis and used "type of exercise" and "study duration" as moderators in subgroup analyses. Standardized mean differences (SMD) for LS- and hip-BMD changes were defined as outcome measures. Seven studies with 17 exercise groups were included in the analysis. We observed significantly higher effects of high (≥2 sessions/week) vs. low net training frequency (1-<2 sessions/week) exercise on LS- (SMD 0.55, 95%-CI: 0.20-0.90) but not hip-BMD (0.19, -0.06 to 0.45). Study duration was found to be a significant moderator for the effect of training frequency at LS- but not hip-BMD. In parallel, the type of exercise moderately influences the effect of training frequency on LS- but not on hip-BMD. We observed a superior effect of higher net training frequency on BMD. Longer exercise exposition increases this effect. Considering e.g. holidays, indisposition or other temporary absence, exercise programs on osteoporosis should provide at least 3 sessions/week/year to allow a net training frequency of more than two sessions/week. STUDY REGISTRATION: PROSPERO (CRD42021246804).

In contrast to postmenopausal women, evidence for a favorable effect of exercise on Bone Mineral Density (BMD) is still limited for men. This might be due to the paucity of studies, but also to the great variety of participants and study characteristics that may dilute study results. The aim of the present systematic review and meta-analysis was to evaluate the effect of exercise on BMD changes with rational eligibility criteria. A comprehensive search of six electronic databases up to 15 March 2021 was conducted. Briefly, controlled trials ≥6 months that determined changes in areal BMD in men >18 years old, with no apparent diseases or pharmacological therapy that relevantly affect bone metabolism, were included. BMD changes (standardized mean differences: SMD) of the lumbar spine (LS) and femoral neck (FN) were considered as outcomes. Twelve studies with 16 exercise and 12 control groups were identified. The pooled estimate of random-effect analysis was SMD = 0.38, 95%-CI: 0.14-0.61 and SMD = 0.25, 95%-CI: 0.00-0.49, for LS and FN, respectively. Heterogeneity between the trials was low-moderate. Funnel plots and rank and regression correlation tests indicate evidence for small study publication bias for LS but not FN-BMD. Subgroup analyses that focus on study length, type of exercise and methodologic quality revealed no significant difference between each of the three categories. In summary, we provided further evidence for a low but significant effect of exercise on BMD in men. However, we are currently unable to give even rough exercise recommendations for male cohorts.

BACKGROUND: Backache is very common in the German population. It is a common reason for people to seek medical advice and specific back pain programs have been developed. The intention of this study is to evaluate the short and long term effects of conservative management of back pain in a German general hospital. Outcomes of interest were pain intensity, interference in daily functions, physical functioning and health related quality of life. PATIENTS AND METHODS: We examined 1010 patients with acute, subacute and chronic back pain, admitted to inpatient nonsurgical interventional therapy in a German hospital between July 2013 and July 2015. Outcomes were assessed at the end of the inpatient treatment and at 3, 6 and 12 months follow-up, using Numerical Rating Scales (NRS) for pain and daily function, the Hannover Ability Questionnaire for Measuring Back Pain-Related Functional Limitations (FFbHâ-âR) and the German Version of the EuroQol Questionnaire (EQ-5D) for measuring health-related quality of life. The baseline questionnaire also included questions on the risk of developing long-term disability following back pain (HKF-R 10) for acute and subacute cases and the Mainz Pain Staging System (MPSS) for patients with chronic back pain. The return rate was 54% after 3 months, 38% after 6 months and 27% at 12 months follow-up. The results from the follow-up measurements (T2â-âT5) were compared to the pre-treatment results (T1). Because of missing or insufficiently normal distributions nonparametric paired Wilcoxon tests were used to test differences over time for each variable. Level of significance was adjusted for multiple testing. In addition, effect sizes were computed to estimate the clinical relevance of statistically significant results. RESULTS: Pain intensity and impact of pain on daily function were significantly lower at the end of the inpatient treatment (T2). The results remained largely stable at the 3, 6 and 12 month follow-ups. Significant improvements were found in physical functioning and health-related quality of life. These improvements were maintained equally at the 3, 6 and 12 month follow-ups. In consequence, working ability increased during the follow-up period. Calculated effect sizes showed large effects for pain intensity, interference and quality of life (r = 0.51 to 0.85) and predominately moderate effects (r = 0.45 to 0.62) for physical functioning at all measurement points. The percentage of patients who had an operation due to continuing back pain after conservative treatment was 7.8, 9.9, and 12.3 at the 3, 6, and 12 month follow-ups, respectively. CONCLUSION: Persistent effects of inpatient conservative treatment of back pain were found for all outcome variables. The specific approach appears to be effective in conservative treatment programs of back pain. In the end, it's not about the alternative of surgery or conservative treatment for back pain. Treatment has to be coordinated with the patient in terms of participative decisions.
