A comparison of outcomes between Canada and the United States in patients recovering from hip fracture repair: secondary analysis of the FOCUS trial

Variation in care for patients presenting with hip fracture in six high-income countries: A cross-sectional cohort study

BACKGROUND

Hip fractures are costly and common in older adults, but there is limited understanding of how treatment patterns and outcomes might differ between countries.

METHODS

We performed a retrospective serial cross-sectional cohort study of adults aged ≥66 years hospitalized with hip fracture between 2011 and 2018 in the US, Canada, England, the Netherlands, Taiwan, and Israel using population-representative administrative data. We examined mortality, hip fracture treatment approaches (total hip arthroplasty [THA], hemiarthroplasty [HA], internal fixation [IF], and nonoperative), and health system performance measures, including hospital length of stay (LOS), 30-day readmission rates, and time-to-surgery.

RESULTS

The total number of hip fracture admissions between 2011 and 2018 ranged from 23,941 in Israel to 1,219,696 in the US. In 2018, 30-day mortality varied from 3% (16% at 1 year) in Taiwan to 10% (27%) in the Netherlands. With regards to processes of care, the proportion of hip fractures treated with HA (range 23%-45%) and THA (0.2%-10%) differed widely across countries. For example, in 2018, THA was used to treat approximately 9% of patients in England and Israel but less than 1% in Taiwan. Overall, IF was the most common surgery performed in all countries (40%-60% of patients). IF was used in approximately 60% of patients in the US and Israel, but only 40% in England. In 2018, rates of nonoperative management ranged from 5% of patients in Taiwan to nearly 10% in England. Mean hospital LOS in 2018 ranged from 6.4 days (US) to 18.7 days (England). The 30-day readmission rate in 2018 ranged from 8% (in Canada and the Netherlands) to nearly 18% in England. The mean days to surgery in 2018 ranged from 0.5 days (Israel) to 1.6 days (Canada).

CONCLUSIONS

We observed substantial between-country variation in mortality, surgical approaches, and health system performance measures. These findings underscore the need for further research to inform evidence-based surgical approaches.

Predictive factors for home discharge after femoral fracture surgery: a prospective cohort study

BACKGROUND

Femoral fractures require protracted hospitalization and often preclude return to pre-fracture levels of mobility, function and prior residential status following hospital discharge. Early prediction of rehabilitation and discharge potential in patients with femoral fracture would optimize discharge planning.

AIM

To identify predictive factors of discharge destination during the early phase of femoral fracture rehabilitation.

DESIGN

Prospective cohort design.

SETTING

Acute and postoperative rehabilitation hospital settings.

POPULATION

Data from 109 participants (65 women [59.6%]) admitted for unilateral femoral fracture were included.

METHODS

Sociodemographic information, hip pain severity during gait (Numeric Pain Rating Scale), mobility (Elderly Mobility Scale), activities of daily living (Modified Barthel Index), cognition (Mini-Mental State Examination [MMSE]), exercise self-efficacy (Self-Efficacy for Exercise Scale), amount of physiotherapy received, and caregiver availability were assessed pre- and/or postoperatively. Discharge destination was assessed via telephone interviews 6 weeks after discharge from acute care. Receiver operating characteristic curves were used to determine optimal cut-off scores for all outcomes based on discharge destination. Outcomes demonstrating a significant area under the curve were entered as dichotomous independent variables (i.e., above or below ROC-derived cut-off values) in subsequent logistic regression analyses to determine predictors of discharge destination.

RESULTS

SEE Score ≥53 (odds ratio [OR]=5.975, 95% confidence interval [CI]=1.674-21.333, P=0.006), female sex (OR=3.421, 95% CI=1.187-9.861, P=0.023), ≥8 physiotherapy sessions (OR=4.633, 95% CI=1.559-13.771, P=0.006), MMSE Score ≥17 (OR=3.374, 95% CI=1.047-10.873, P=0.042), and caregiver availability (OR=3.766, 95% CI=1.133-12.520, P=0.030) were identified as significant predictors of home discharge.

CONCLUSIONS

Exercise self-efficacy, female sex, more physiotherapy rehabilitation training, better pre-operative cognitive function, and caregiver availability emerged as important predictors of home discharge following femoral fracture.

CLINICAL REHABILITATION IMPACT

These findings are highly translational and may be useful for informing clinical guidelines and policy decisions regarding rehabilitation potential and discharge pathway selection during early hospitalization following femoral fracture surgery.

Effect of referral systems on costs and outcomes after hip fracture surgery in Taiwan

OBJECTIVE

To explore the economic burdens of hip fracture surgery in patients referred to lower-level medical institutions and to evaluate how referral systems affect costs and outcomes of hip fracture surgery.

DESIGN

A nationwide population-based retrospective cohort study.

SETTING

All hospitals in Taiwan.

PARTICIPANTS

A total of 7500 patients who had received hip fracture surgery (International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes 820.0 ∼ 820.9 and procedure codes 79.15, 79.35, 81.52, 81.53) performed in 1997 to 2013.

MAIN OUTCOME MEASURES

Total costs including outpatient costs, inpatient costs and total medical costs and medical outcomes including 30-day readmission, 90-day readmission, infection, dislocation, revision and mortality.

RESULTS

The patients were referred to a lower medical institution after hip fracture surgery (downward referral group) and 3034 patients continued treatment at the same medical institution (non-referral group). Demographic characteristics, clinical characteristics and institutional characteristics were significantly associated with postoperative costs and outcomes (P < 0.05). On average, the annual healthcare cost was New Taiwan Dollars (NT$)2262 per patient lower in the downward referral group compared with the non-referral group. The annual economic burdens of the downward referral group approximated NT$241 million (2019 exchange rate, NT$30.5 = US$1).

CONCLUSIONS

Postoperative costs and outcomes of hip fracture surgery are related not only to demographic and clinical characteristics, but also to institutional characteristics. The advantages of downward referral after hip fracture surgery can save huge medical costs and provide a useful reference for healthcare authorities when drafting policies for the referral system.

Is it feasible to implement a rapid recovery pathway for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion in a single-payer universal health care system?

PURPOSE

The purpose of this project was to determine if it is feasible to implement a rapid recovery pathway (RRP) for the surgical treatment of adolescent idiopathic scoliosis (AIS) within a single-payer universal healthcare system while simultaneously decreasing length of stay (LOS) without increasing post-operative complications.

METHODS

A retrospective analysis was completed for all patients who underwent posterior spinal fusion for AIS at a tertiary children's hospital in Canada between March 2010 and February 2019, with date of implementation of the RRP being March 1st, 2015. Patient demographic information was collected along with a variety of outcome variables including: LOS, wound complication, infection, 30-day return to the OR, 30-day emergency department visit, and 30-day hospital readmission. An interrupted time series analysis was utilized to determine if any benefits were associated with the implementation of the RRP.

RESULTS

A total of 244 patients were identified, with 113 patients in the conventional pathway and 131 in the RRP. No significant differences in demographic features or post-operative complications were found between the two cohorts (p > 0.05). Using a robust linear time series model, LOS was found to be significantly shorter in the RRP group, with the average LOS being 5.2 [95% IQR 4.3-6.1] days in the conventional group and 3.4 [95% IQR 3.3-3.5] days in the RRP group (p < 0.05).

CONCLUSION

This study shows that it is possible to implement a RRP for the surgical treatment of AIS within a single-payer universal healthcare system. Use of the pathway can effectively reduce hospital LOS without increasing the risk of developing a post-operative complication. This has the upside potential to reduce healthcare and family costs.

Hip fractures in South Africa: mortality outcomes over 12 months post-fracture

With increased urbanisation and longevity in sub-Saharan Africa, the burden of osteoporosis and resultant hip fractures (HF) has increased. This study shows that 1 in 3 subjects dies post-HF, and that there are significant delays and barriers to surgery, reflecting the need to prioritise HF care in South Africa.

PURPOSE

The outcomes following hip fractures are unknown in sub-Saharan Africa. This study aimed to quantify the mortality rate (MR) following hip fractures and to identify predictors of mortality over 1 year.

METHODS

In this cohort study, demographic, clinical, and biochemical characteristics of consecutive patients with low trauma hip fractures, admitted to the five public sector hospitals in eThekwini (formerly Durban), were recorded. Cox regression analyses identified predictors of mortality at 30 days and 1 year.

RESULTS

In the 200 hip fracture patients studied, the mean age was 74.3 years (SD ± 8.8) and 72% were female. Hospital presentation was often delayed, only 15.5% presented on the day of fracture. At admission, 69.5% were anaemic, 42% had hyponatraemia, 34.5% raised creatinine, and 58.5% hypoalbuminaemia. All received skin traction before 173 (86.5%) underwent surgical fixation. Median time from admission to surgery was 19.0 days (IQR 12.3-25.0). Median hospital stay was 9.0 days (IQR 12.3-25.0). Mortality rates were 13% and 33.5% at 30 and 365 days, respectively. Over 1 year, African patients were more likely to die than Indian patients (40.9 versus 30%, HR 11.5 [95% CI 1.51, 2.57]; p = 0.012); delays to surgery predicted death (HR 1.02 [95% CI (1.00, 1.04)]; p = 0.022). In multivariate analyses, death at 1 year was most strongly predicted by an elevated serum creatinine (HR 2.43, 95% CI (1.02, 5.76), p = 0.044].

CONCLUSION

Hip fractures are associated with high MRs, in part explained by insufficient surgical capacity, highlighting the need for national efforts to improve hip fracture service provision.

[Functional and clinical outcomes in patients admitted to nursing homes after hip fractures. Implementation of a multi-level intervention program]

BACKGROUND AND OBJECTIVE

The aim of this study was to determine the clinical and functional outcomes of patients discharged to nursing homes after a hip fracture.

METHODS

The study included all patients admitted to a group of nursing homes after a hip fracture in 2016. A geriatric assessment protocol was applied, and patients were treated with a specific protocol for 90 days. They were assessed for nutritional status (Mini-Nutritional Assessment and Body Mass Index), pain (Visual Analogue Scale, and the PAINAD Scale), the presence of pressure ulcers, blood test (D vitamin, haemoglobin, proteins), and functional status (Barthel index and Functional Assessment Categories).

RESULTS

Out of a total of 175 patients, 116 (75%) met the inclusion criteria. The mean age was 84.9 years old (±6.7 SD), and 91 (78.4%) were women. At admission, 73.8% of 65 residents had anaemia, 76.7% hypovitaminosis D, 88% malnutrition or «at risk of malnutrition», and 15.3% had pressure ulcers. After 90 days, the moderate-severe functional status (Barthel index < 60) was reduced from 90.4 to 39.6%, dependence due to gait from 97.3 to 36.1%, and moderate-severe pain from 88.9 to 14.4%. Most of the pressure ulcers healed (94.4%).

CONCLUSIONS

Patients admitted to nursing homes after a hip fracture had poor clinical and functional status. This study shows that after 90 days from admission these patients had positive outcomes in terms of functionality, gait, pain control, and pressure ulcers healing.

Discharge destination following hip fracture in Canada among previously community-dwelling older adults, 2004-2012: database study

Little is known about post-acute care following hip fracture surgery. We investigated discharge destinations from surgical hospitals for nine Canadian provinces. We identified significant heterogeneity in discharge patterns across provinces suggesting different post-acute recovery pathways. Further work is required to determine the impact on patient outcomes and health system costs.

INTRODUCTION

To examine discharge destinations by provinces in Canada, adjusting for patient, injury, and care characteristics.

METHODS

We analyzed population-based hospital discharge abstracts from a national administrative database for community-dwelling patients who underwent hip fracture surgery between 2004 and 2012 in Canada. Discharge destination was categorized as rehabilitation, home, acute care, and continuing care. Multinomial logistic regression modeling compared proportions of discharge to rehabilitation, acute care, and continuing care versus home between each province and Ontario. Adjusted risk differences and risk ratios were estimated.

RESULTS

Of 111,952 previously community-dwelling patients aged 65 years or older, 22.5% were discharged to rehabilitation, 31.6% to home, 27.0% to acute care, and 18.2% to continuing care, with significant variation across provinces (p < 0.001). The proportion of discharge to rehabilitation ranged from 2.4% in British Columbia to 41.0% in Ontario while the proportion discharged home ranged from 20.3% in Prince Edward Island to 52.2% in British Columbia. The proportion of discharge to acute care ranged from 15.2% in Ontario to 58.8% in Saskatchewan while the proportion discharged to continuing care ranged from 9.3% in Manitoba and Prince Edward Island to 22.9% in New Brunswick. Adjusting for hospital type changed the direction of the provincial effect on discharge to continuing care in two provinces, but statistical significance remained consistent with the primary analysis.

CONCLUSIONS

Discharge destination from the surgical hospital after hip fracture is highly variable across nine Canadian provinces. Further work is required to determine the impact of this heterogeneity on patient outcomes and health system costs.

Predicting discharge placement after elective surgery for lumbar spinal stenosis using machine learning methods

PURPOSE

An excessive amount of total hospitalization is caused by delays due to patients waiting to be placed in a rehabilitation facility or skilled nursing facility (RF/SNF). An accurate preoperative prediction of who would need a RF/SNF place after surgery could reduce costs and allow more efficient organizational planning. We aimed to develop a machine learning algorithm that predicts non-home discharge after elective surgery for lumbar spinal stenosis.

METHODS

We used the American College of Surgeons National Surgical Quality Improvement Program to select patient that underwent elective surgery for lumbar spinal stenosis between 2009 and 2016. The primary outcome measure for the algorithm was non-home discharge. Four machine learning algorithms were developed to predict non-home discharge. Performance of the algorithms was measured with discrimination, calibration, and an overall performance score.

RESULTS

We included 28,600 patients with a median age of 67 (interquartile range 58-74). The non-home discharge rate was 18.2%. Our final model consisted of the following variables: age, sex, body mass index, diabetes, functional status, ASA class, level, fusion, preoperative hematocrit, and preoperative serum creatinine. The neural network was the best model based on discrimination (c-statistic = 0.751), calibration (slope = 0.933; intercept = 0.037), and overall performance (Brier score = 0.131).

CONCLUSIONS

A machine learning algorithm is able to predict discharge placement after surgery for lumbar spinal stenosis with both good discrimination and calibration. Implementing this type of algorithm in clinical practice could avert risks associated with delayed discharge and lower costs. These slides can be retrieved under Electronic Supplementary Material.

Advancing International Research on Long-Term Care: Using Adaptive Leadership to Build Consensus on International Measurement Priorities and Common Data Elements

International research on long-term care (LTC) can valuably inform LTC policy and practice, but limited transnational collection of data on key LTC issues restricts the contributions of international LTC research. This special collection of Gerontology and Geriatric Medicine helps close the gap between the status quo and the potential for international LTC research by cultivating a transnational common ground of internationally prioritized measurement concepts and sowing the seeds of international LTC common data elements. The articles in this special collection address both adaptive and technical challenges to international LTC measurement, build on and complement existing LTC measurement systems, and provide diverse international perspectives on the measurement of LTC across four overarching domains: LTC contexts, workforce and staffing, person-centered care, and care outcomes. From large transnational teams of scholars specifying the meanings of central LTC concepts, to smaller subnational research teams testing new measures of person-centered care across diverse local LTC settings, contributors spark new insights and point in new directions for a LTC measurement infrastructure supportive of person-centered care and lifelong thriving.
