Is treatment of geriatric hip fracture patients cost-covering? Results of a prospective study conducted at a German University Hospital

Substantial changes in fracture rates in German hospitals in 2018 compared with 2002: an epidemiological study

INTRODUCTION

The aim of this study was to present recent epidemiological data on extremity and axial skeletal fractures in German hospitals and to compare them with older data to detect time trends.

MATERIALS AND METHODS

Inpatient data from the German National Hospital Discharge Registry were used. The absolute number and age-standardized incidence of fractures in 2002 and 2018 were analysed by fracture location according to the International Classification of Disease. Data were analysed according to age group. Male: female ratios (MFRs) and incidence rate ratios (IRRs) were calculated to compare the 2018 and 2002 data.

RESULTS

The absolute number of fractures of the nine analysed locations was 15.2% higher in 2018 than in 2002. By fracture location, the changes were as follows (absolute change + IRR): "neck" (S12): + 172%, IRR = 2.6; "rib(s), sternum, thoracic spine" (S22): + 57%, IRR = 1.3; "lumbar spine and pelvis" (S32): + 66%, IRR = 1.3; "shoulder and upper arm" (S42): + 36%, IRR = 1.2; "forearm" (S52): + 13%, IRR = 1.0; "wrist and hand level" (S62): - 32%, IRR = 0.7; "femur" (S72): + 24%, IRR = 0.9; "lower leg, including ankle" (S82): - 24%, IRR = 0.7; "foot, except ankle" (S92): - 4%, IRR = 0.9. The overall MFR changed from 0.7 in 2002 to 0.6 in 2018. The age group of 45-54 years represented a turning point, males were more often affected than females in the younger age groups, and the opposite trend was observed in the older age groups.

CONCLUSIONS

The increase in the absolute fracture rates was due to increased rates of femur, shoulder, upper arm, forearm, and axial skeletal fractures, with elderly women being the main contributors. Femur fractures were found to be the most common fractures treated in German hospitals.

Changing epidemiology of lower extremity fractures in adults over a 15-year period - a National Hospital Discharge Registry study

Background

Demographic changes led to an increasingly ageing population in Germany and thus to possible changes in the frequency of fractures. The primary aim of this study was to report changes in fracture rates of the lower extremities in Germany in 2002 compared to 2017 and to evaluate those changes.

Methods

Inpatient data from the German National Hospital Discharge Registry (ICD10) for 2002 and 2017 were evaluated. Changes in total counts and incidence rates were analysed for fractures in the following locations: femoral neck, pertrochanteric, subtrochanteric, distal femur, femoral shaft, proximal and distal tibia, tibial shaft, medial and lateral malleolus, and other parts of the lower leg (including bi- and trimalleolar fractures), calcaneus, talus, other tarsal bones, metatarsal bones, greater toe, lesser toe, other fractures of foot or unspecific fractures of foot and toe. Patients were classed into age groups by sex: 15–24, 25–34,35–44, 45–54, 55–64, 65–74, 75–84, 85–90 and >  90 years.

Results

The total count for lower extremity fractures in men and women increased slightly by 4.5% from 305,764 in 2002 to 319,422 in 2017. Hip and femur fractures increased by 23.5% from 150,565 in 2002 to 185,979 in 2017. The number of these fractures among men increased by 46% and among women by 15.3%. The total count of lower leg fractures decreased by 15.4% from 131,162 in 2002 to 110,924 in 2017. Especially, younger age groups showed a decline for all tibial segments and ankle fractures. For both sexes, the number of lower leg fractures in those 75 years or older increased in all lower leg fracture locations. Most femur and lower leg fractures occurred in women. The incidence of fractures rose sharply from 2002 to 2017, especially for older cohorts.

Conclusion

The total numbers of lower extremity fractures increased slightly in 2017 compared to 2002 – especially hip and femur fractures among men. The incidence of almost all lower extremity fracture types among older people increased during this time. Women were particularly affected. Therefore, focused prevention programmes should be considered including an extended fracture spectrum in the elderly.

Financial Implications for the Treatment of Medicare Patients With Isolated Intertrochanteric Femur Fractures: Disproportionate Losses Among Healthier Patients

Introduction:

With an aging American public, the rising incidence of geriatric hip fractures provides a significant impact on the financial sustainability for hospitals. To date, there is little research comparing reimbursement to hospital costs for geriatric hip fracture treatment. The purpose of this study is to compare hospital costs to reimbursement for patients treated surgically with an isolated intertrochanteric femur fracture, insured by the Center of Medicare and Medicaid Services (CMS).

Materials and Methods:

A retrospective review at an urban, academic, level 1 trauma center was conducted for 287 CMS-insured intertrochanteric femur fracture patients between 2013 and 2017. The total cost of care was determined using our hospital’s cost accounting system. The total reimbursement was determined from the CMS inpatient prospective payment system, based upon the Medical-Severity Diagnosis-Related Grouping (MS-DRG).

Results:

In this patient population, the average CMS reimbursement was US$19 049 ± 7221 and the average cost of care was US$19 822 ± 8078. This yielded a net deficit of US$773/patient and US$220 417 in total. The average reimbursement and cost for the less comorbid patients (MS-DRG weight < 2.5, n = 215) was US$16 198 ± 3983 and US$17 764 ± 5628, respectively, yielding an average net deficit of US$1566/patient. For the more comorbid patients (MS-DRG weight > 2.5, n = 72) the mean reimbursement and cost were US$27 796 ± 3944 and US$26 180 ± 10 880, respectively, yielding an average net profit of US$1616/patient.

Discussion:

There are disproportionate average losses in healthier patients undergoing surgical treatment of intertrochanteric femur fractures at our institution. A deficit in less comorbid patients indicates a discontinuity of inpatient health-care costs with MS-DRG-weighted reimbursement in the setting of geriatric intertrochanteric femur fractures.

Conclusions:

To maintain hospitals’ financial sustainability and health-care accessibility; costing and reimbursement models need adjusting to properly compensate the treatment of geriatric intertrochanteric femur fractures.

Level of Evidence:

Diagnostic level IV.

Medical and economic consequences of perioperative complications in older hip fracture patients

Patients suffering from complications during inpatient treatment after hip fracture surgery are associated with a worse mid-term outcome. While surgically treatable complications only delay the healing process, internal complications seem to worsen the outcome in the long run. All complications come with significant increased costs during the hospital stay.

PURPOSE

Due to the demographic changes, the importance of hip fractures is still increasing nowadays. Not only surgical but also medical complications represent a major challenge in the treatment of those patients. Nevertheless, only few is known about the functional, medical, and economic consequences of complications.

METHODS

A total of 402 hip fracture patients ≥ 60 years were observed prospectively at a German university hospital. Complications were assessed during the inpatient stay and classified by Clavien and Dindo. Afterwards their influence on acute care costs was examined as well as their influence on the mortality, health-related quality of life (HRQL) (EQ5D), functional capacities (Barthel index), and mobility (Tinetti score) in the follow-up periods of 6 and 12 months.

RESULTS

Complications that required surgical revision/treatment (type III) were associated with an increased 6 months' mortality, while type II and IV complications did not influence mortality after 6 and 12 months. Six months after surgery, HRQL, Barthel score, and Tinetti score were reduced in patients suffering from all different types of complications. After 12 months however, HRQL, Barthel score, and Tinetti score following type II and IV complications remained reduced, while the scores improved in patients suffering from type III complication. All types of complications led to significantly increased acute care costs.

CONCLUSIONS

The results of the present study emphasize the crucial role of perioperative complications in older patients with hip fractures. Therefore, special attention has to be given to the prevention of those complications, e.g., with orthogeriatric treatment models, which have been shown to be effective in the reduction of complications.

[Evaluation of a simple screening tool for ambulant fall prevention]

BACKGROUND

An individual's risk of falling is generally difficult to detect and it is likely to be underestimated. Thus, preventive measures are challenging and they demand sufficient integration and implementation into aftercare and outpatient management. The Aachen Falls Prevention Scale (AFPS) is a quick and easy tool for patient-driven fall risk assessment. Older adults' risk of falling is identified in a suitable manner and they then have the opportunity to independently assess and monitor their risk of falling.

OBJECTIVES

The aim of the current study was to evaluate the AFPS as a simple screening tool in geriatric trauma patients via the identification of influencing factors, e.g. objective or subjective fall risk, fear of falling (FOF) and demographic data. In this context, we investigated older adults' willingness to take part in special activities concerning fall prevention.

METHODS

Retrospectively, all patients over 70 years of age who received in-hospital fracture treatment between July 2014 and April 2016 were analyzed at a level I trauma center. After identification of 884 patients, participants completed a short questionnaire (47 questions, yes/no, Likert scale) comprising the AFPS. A history of falls in the past year was considered an indicator of a balance disorder. In addition, ambulant patients were invited to participate between July and August 2016.

RESULTS

In total, 201 patients (mean 80.4 years, range 63-97 years) performed a self-assessment based on the AFPS. After steps 1 and 2 of the AFPS had been completed, 95 (47%) participants rated their subjective risk of falling as high (more than 5 points). Of the participants 84 (42%) were objectively classified as "fallers" with significant effects on their AFPS evaluation and rating of their subjective risk of falling. Furthermore, 67% of the participants identified a general practitioner as their main contact person, and 43% of the respondents viewed the AFPS as a beneficial screening tool in fall risk evaluation (8% negative attitudes). Only 12% of the participants could imagine using the AFPS app version as a feasible option.

CONCLUSION

It would be advantageous to pretest at-risk individuals in their environment using a simple self-assessment approach, with the main purpose of identifying potential balance problems. With this approach, cost savings in the healthcare system are possible, combined with a higher health-related quality of life in the geriatric population.

Development of the Barthel Index 5 years after hip fracture: Results of a prospective study

AIM

The importance of proximal femoral fractures is increasing due to demographic change. Despite appropriate care, these are associated with poor results. We are still lagging behind, and require information on the long-term functional outcome of these patients and the predictive factors involved.

METHODS

Between 2009 and 2011, 402 patients aged >60 years with hip fractures were included in this prospective observational study. Patients were assessed with the Barthel Index before fracture, at discharge, and 6 months, 1 year and 5 years after surgery. In addition, a variety of parameters (sex, age, fracture type, American Society of Anesthesiologists classification, Mini-Mental State Examination, housing situation, occurrence of complications during inpatient stay and type of care) were collected to identify the possible independent predictive factors using multivariate analysis.

RESULTS

The lowest Barthel Index was found at discharge (66 ± 24) for patients from an acute hospital. The Barthel Index improved within the first 6 months (86 ± 21) and decreased afterwards. The factors associated with a significantly higher point loss of the Barthel Index in the multivariate analysis were age (P-value 0.020), pre-fracture Barthel Index, (P ≤ 0.001), Mini-Mental State Examination (P ≤ 0.001) and type II complications (P = 0.001). The other values showed no significant influence on the Barthel Index.

CONCLUSIONS

The present results showed that patients after a hip fracture have a great rehabilitation potential within the first 6 months after the event. More attention should be paid to type II complications and the occurrence of cognitive impairment. Both seem to be a surrogate parameter for the frailty of the patients.
