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.

Objective: To evaluate a novel healthcare programme for the treatment of patients with hip and knee osteoarthritis in southern Germany in terms of clinical and health economic outcomes. The study is based on claims data from 2014 to 2017. Methods: We conducted a retrospective comparative cohort study of 9768 patients with hip and knee osteoarthritis, of whom 9231 were enrolled in a collaborative ambulatory orthopaedic care programme (intervention group), and 537 patients received usual orthopaedic care (control group). Key features of the programme are coordinated care, morbidity-adapted reimbursement and extended consultation times. Multivariable analysis was performed to determine effects on health utilisation outcomes. The economic analysis considered annual costs per patient from a healthcare payer perspective, stratified by healthcare service sector. Besides multivariable regression analyses, bootstrapping was used to estimate confidence intervals for predicted mean costs by group. Results: Musculoskeletal-disease-related hospitalisation was much less likely among intervention group patients than control group patients [odds ratio (OR): 0.079; 95% CI: 0.062-0.099]. The number of physiotherapy prescriptions per patient was significantly lower in the intervention group (RR: 0.814; 95% CI: 0.721-0.919), while the likelihood of participation in exercise programmes over one year was significantly higher (OR: 3.126; 95% CI: 1.604-6.094). Enrolment in the programme was associated with significantly higher ambulatory costs (1048 vs. 925), but costs for inpatient care, including hospital stays, were significantly lower (1003 vs. 1497 and 928 vs. 1300 respectively). Overall annual cost-savings were 195 per patient. Conclusions: Collaborative ambulatory orthopaedic care was associated with reduced hospitalisation in patients with hip and knee osteoarthritis. Health costs for programme participants were lower overall, despite higher costs for ambulatory care.
RESUMO
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: In 2014, the novel orthopedic care program was established by the AOK health insurance fund in southern Germany to improve ambulatory care for patients with musculoskeletal disorders. The program offers extended consultation times, structured collaboration between general practitioners and specialists, as well as a renewed focus on guideline-recommended therapies and patient empowerment. The aim of this study was to assess the impact of the program on health service utilization in patients with hip and knee osteoarthritis (OA). METHODS: This retrospective cohort study, which is based on claims data, evaluated health service utilization in patients with hip and knee OA from 2014 to 2017. The intervention group comprised OA patients enrolled in collaborative ambulatory orthopedic care, and the control group received usual care. The outcomes were participation in exercise interventions, prescription of physical therapy, OA-related hospitalization, and endoprosthetic surgery rates. Generalized linear regression models were used to analyze the effect of the intervention. RESULTS: Claims data for 24,170 patients were analyzed. Data for the 23,042 patients in the intervention group were compared with data for the 1,128 patients in the control group. Participation in exercise interventions (Odds Ratio (OR): 1.781; 95% Confidence Interval (CI): 1.230-2.577; p = 0.0022), and overall prescriptions of physical therapy (Rate Ratio (RR): 1.126; 95% CI: 1.025-1.236; p = 0.0128) were significantly higher in the intervention group. The intervention group had a significantly lower risk of OA -related hospitalization (OR: 0.375; 95% CI: 0.290-0.485; p < 0.0001). Endoprosthetic surgery of the knee was performed in 53.8% of hospitalized patients in the intervention group vs. 57.5% in the control group; 27.7% of hospitalized patients underwent endoprosthetic surgery of the hip in the intervention group versus 37.0% in the control group. CONCLUSIONS: In patients with hip and knee OA, collaborative ambulatory orthopedic care is associated with a lower risk of OA-related hospitalization, higher participation in exercise interventions, and more frequently prescribed physical therapy.

BACKGROUND: Back pain is one of the leading causes of disability globally and the most common musculoskeletal pain in Germany. The lifetime prevalence of back pain ranges from 74% to 85%, and the point prevalence ranges from 32% to 49%. One in five individuals with statutory health insurance visits a doctor at least once a year for back pain, and 1 in 20 individuals is on sick leave at least once a year. The question as to what extent can different outpatient care concepts substantially contribute to improving care and avoiding inpatient hospital treatment has repeatedly been the subject of controversial political discussions. This study aimed to present a description of the reality of care in Baden-Württemberg (BW), Germany, based on claims data. MATERIAL AND METHODS: Anonymised routine billing data of AOK Baden-Württemberg were analysed in compliance with data protection regulations. The billing data cover the outpatient and inpatient care sectors. All AOK patients in BW who received at least one ICD10 diagnosis from their physician in the first half of 2015 were considered for the analysis. Patients with at least one diagnosis of back pain were evaluated as patients with back pain, whereby the assignment to the diagnosis group of specific or non-specific back pain was made based on the code. RESULTS: In the first half of 2015, nearly 988â925 patients with back pain were registered in the 6696 primary care clinics in BW, approximately 302â524 patients in 1172 orthopaedic clinics and 17â043 patients in 89 neurosurgical clinics. Primary care clinics reported back pain diagnosis in 34.6%, orthopaedic clinics in 51.9% and neurosurgical clinics in 78.6% of cases. Primary care clinics diagnosed a specific cause in approximately one-third of patients with back pain, orthopaedic clinics in approximately 40% of their patients and neurosurgery clinics in one in two cases. Overall, approximately 1.2% of 1.3 million patients with back pain (January to December 2015 in BW) were hospitalised. Inpatient therapy consisted of surgical therapy and conservative therapy. Nucleotomy, decompression and spondylodesis were the three most common surgical procedures performed. Pain medication and remedy prescriptions decreased pain after spinal surgery. There are significant regional differences in referral and surgery rates. The mean inpatient referral rate was 535 of 100â000 AOK insurants, and the median was 536 of 100â000 AOK insurants. The mean surgery rate among all admitted patients with back pain was 49.9%, and the median was 49.8%. CONCLUSION: The vast majority of patients with back pain are treated as outpatients. Only approximately 1.2% of all patients with back pain were treated as inpatients in 2015. Of these, approximately half underwent surgery. Spinal surgeries led to a decrease in pain medication and remedy prescription postoperatively. The three most frequent surgical procedures were 'decompression', 'excision of disc tissue' and 'spondylodesis'. There were significant regional differences.

BACKGROUND: Due to demographic changes an increasing number of hip osteoarthritis can be expected with corresponding effects on the health care system. Hence, the objectives of our study were to obtain substantiated evidence about current medical care situation of hip osteoarthritis patients including outpatient care situation and hip replacement surgery. PATIENTS AND METHODS: Overall, the medical care data of 2.4 million insurees of the AOK Baden-Württemberg for the years 2007 to 2016 were analyzed. Lower limit of age was 40 years. The data includes outpatient and inpatient healthcare claims. RESULTS: The age standardized prevalence of hip osteoarthritis in adults aged 40 years or older is 6.18% (95% CI: ± 0.09%) among women and 6.02% (95% CI: ± 0.09%) among men. From the age of 75, sex differences become significant. The maximum number of newly diagnosed cases of hip osteoarthritis (women: 1.31%, men: 1.16%) is found in the 80â-â84-year-olds. From the age of 85, 17.4% of all women and 16.5% of all men show a hip osteoarthritis. The maximum number of hip replacement surgery among osteoarthritis patients (women: 5.2%, men: 4.3%) appears in the 75- to 79-year-olds. After the initial diagnosis of a hip osteoarthritis, every eighth (13.0%) AOK insured person receives a hip replacement surgery within the first year and one in four (24.8%) insurees within 8 years. Irrespective of the main diagnosis, numbers of hip replacement surgery did not increase between 2009 and 2016. On average, 300.9 (women) and 275.8 (men) hip replacement surgeries were performed per 100â000 insured years. From the age of 80, hip osteoarthritis drops back as the main diagnosis fur surgery. Consequently, from the age of 85 more than 70% of all hip replacement patients show a femoral fracture as main diagnosis. Only about ¾ of the hip osteoarthritis patients were in outpatient specialist care in the year before surgery, and far less than half of hip osteoarthritis patients received a referral to physiotherapy. CONCLUSION: Osteoarthritis of the hip occurs approximately equally often in women and men up to the age of 75 years. Nevertheless, women underwent surgery more frequently. Overall, the number of hip replacement surgery has not increased in the last eight years. Within the first eight years after initial diagnosis of hip osteoarthritis 24.8% of all patients receive a hip TEP. Hence, the majority of patients is treated conservatively in the first eight years. A direct comparison between incidence and prevalent hip osteoarthritis patients reveals that after many years of therapeutic care in the last 1â-â2 years prior to surgery, both the specialist care as well as the referral to physiotherapy are reduced. A reassessment of conservative treatment options over time seems to be necessary.

Background In 2015 a survey was conducted in Baden-Württemberg (Germany) among patients treated by orthopaedic specialists participating in a medical specialists' contract between doctors and statutory health insurance funds, in accordance with § 73c of the German Social Code, Book V (SGB V). This contract aims to improve orthopaedic care by structured cooperation between orthopaedic specialists and general practitioners, who are the central coordinators of care, and refer patients to a specialist if necessary. The program is intended to achieve patient-centred care by taking into account the physical, psychological and social aspects of the patients' orthopaedic complaints, as well as informing and motivating patients for self-management and health promoting activities. The survey was intended to receive feedback on the quality of care from the patients enrolled in this medical specialists' program, particularly concerning the specific aims of the program. A feedback report with individual results and a comparison with the overall results of all participating medical practices was sent out to those practices that provided at least 20 analysable questionnaires. Material and Methods The anonymous survey was conducted using a questionnaire specifically developed for the project. Participating practices handed out questionnaires to up to 100 patients who were enrolled in the program and consulted their orthopaedic or surgical specialist within 3 months of the start of the survey. Completed questionnaires were collected and sent to the research institute for data analysis in a sealed box. Results A total of 10,010 patients from 267 practices took part in the survey. Data analysis (including an anonymous comparison of the results of participating practices) was conducted on the basis of patients' responses from 183 practices that had obtained at least 20 completed questionnaires (8,988 patients, response rate 49.1%). Survey results are presented on doctor-patient communication, scheduling appointments, waiting times, cooperation with general practitioner, referral and treatment. On the whole, patients were satisfied with the care provided by their orthopaedic or surgical specialist. The comparison between the practices revealed significant differences in the patients' sociodemographic features and their feedback on the medical care received. Patients' evaluation of information and the counselling received from their orthopaedic/surgical specialist showed the strongest correlation with overall satisfaction. Referral by their general practitioner had a positive influence on patients' intentions to consult their orthopaedic/surgical specialist again. From the patients' point of view, doctors' information and counselling on self-help activities (e.g. eating habits, physical activity) had the largest potential for improvement. Conclusions The survey's results confirm the objectives of this new orthopaedic health care program, especially motivational counselling on adequate physical activity and self-management. They provide a basis for the further development of the quality of care, in accordance with both the contractual aims and the patients' needs.

BACKGROUND: Modern navigation techniques allow precise positioning of the acetabular cup relative to the anterior pelvic plane. Variations in pelvic tilt will affect the resulting spatial orientation of the cup. METHODS: We measured pelvic tilt in 30 volunteers with an inclinometer combined with an ultrasonographic position measurement system. A mathematical algorithm was developed to calculate the resulting cup position measured on standard radiographs, depending on pelvic tilt. RESULTS: Average pelvic tilt at rest was -4 degrees in the lying position and -8 degrees in the standing position, and ranged from -27 degrees to +3 degrees. Pelvic reclination of 1 degree will lead to functional anteversion of the cup of approximately 0.7 degree. INTERPRETATION: Pelvic tilt makes navigation systems referring to the anterior plane inaccurate.

Poly-L-lactic acid (PLLA) bioabsorbable interference screws are widely used for fixation of tendon to bone and bone to bone in anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstructions. Complications are rare. To our knowledge this is the first report of severe chondral damage caused by late breakage of the screw. Breakage of bioscrews has only been published in cases with tendon to bone fixation.
