Ontology highlight
ABSTRACT: Introduction
Socioeconomic factors have an impact on outcomes in hip fracture patients. This study aims to determine if there is a difference in hospital length of stay (LOS) and total hospital charge between income quartiles in hospitalized hip fracture patients.Methods
National Inpatient Sample (NIS) data from 2016 to 2018 was used to determine differences in LOS, total charge, and other demographic/clinical outcomes by income quartile in patients hospitalized for hip fracture. Multivariate regressions were performed for both LOS and total hospital charge to determine variable impact and significance.Results
There were 860,045 hip fracture patients were included this study. With 222,625 in the lowest income quartile, 234,215 in the second, 215,270 in the third, and 190,395 in the highest income quartile. LOS decreased with increase in income quartile. Total charge was highest in the highest quartile, while it was lowest in the middle two-quartiles. Comorbidities with the largest magnitude of effect on both LOS and total charge were lung disease, kidney disease, and heart disease. Time to surgery post-admission also had a large effect on both outcomes of interest.Conclusion
The results demonstrate that income quartile has an effect on both hospital LOS and total charge. This may be the result of differences in demographics and other clinical variables between quartiles and increased comorbidities in lower income levels. The overall summation of these socioeconomic, demographic, and medical factors affecting patients in lower income levels may result in worse outcomes following hip fracture.

Project description:Background and purposeHospital volume has been suggested to be one of the best indicators of adverse orthopedic events in patients undergoing THR surgery. We therefore evaluated the effect of hospital volume on the length of stay, re-admissions, and complications of THR at the population level in Finland.Methods30,266 THRs performed for primary osteoarthritis were identified from the Hospital Discharge Register. Hospitals were classified into 4 groups according to the number of THRs performed on an annual basis over the whole study period: 1-50 (group 1), 51-150 (group 2), 151-300 (group 3), and > 300 (group 4).ResultsIn 2005, the length of the period of surgical treatment was 5.5 days in group 4 and 6.8 days in group 1 (the reference group). During the whole study period (1998-2005), the length of surgical treatment period was shorter in group 4 than in group 1 (p < 0.001). The odds ratio for dislocations (0.7, 95% CI: 0.6-0.9) was lower in group 3 than in group 1.InterpretationHip replacements performed in high-volume hospitals reduce costs by shortening the length of stay, and they may reduce the dislocation rate.

Project description:BackgroundThe Blue Book (2005), recommended guidelines for patients care with fragility fractures. Together with introduction of a National Hip Fracture Database Audit and Best Practice Tariff model to financially incentivise hospitals by payment of a supplement for patients whose care satisfied six clinical standards), have improved hip fracture after-care. However, there is a lack of data-driven evidence to support its effectiveness. We aimed to verify the impact of an orthogeriatric service on hospital length of stay (LOS)-duration from admission to discharge.MethodsWe conducted a repeated cross-sectional study over a 10 year period of older individuals aged ≥ 60 years admitted with hip fractures to a hospital.ResultsAltogether 2798 patients, 741 men and 2057 women (respective mean ages; 80.5 ± 10.6 and 83.2 ± 8.9 years) were admitted from their own homes with a hip fracture and survived to discharge. Compared to 2009-2014, LOS during 2015-2019, when the orthogeriatric service was fully implemented, was shorter for all discharge destinations: 10.4 vs 17.5 days (P < 0.001). Each discharge destination showed reductions: back to own homes, 9.7 vs 17.7 days (P < 0.001); to rehabilitation units: 10.8 vs 13.1 days (P < 0.001); to residential care: 15.4 vs 26.2 days (P = 0.001); or nursing care, 24.4 vs 53.1 days (P < 0.001). During 2009-2014, the risk of staying > 3 weeks in hospital was greater by six-fold and pressure ulcers by three-fold. The number of bed days for every thousand patients per year was also shortened during 2015-2019 by: 1665 days for discharge back to own homes; 469 days with transfer to rehabilitation units; 1258 days for discharge to residential care, and 5465 days to nursing care. Estimated annual savings (2017 costs) per thousand patients after complete establishment of the service was about £2.7 m.ConclusionsImplementation of an orthogeriatric service generated significant reductions in hospital LOS for all patients, with associated cost-savings, especially for those discharged to nursing care.

Project description:ObjectiveTo investigate relation between inpatient length of stay after hip fracture and risk of death after hospital discharge.SettingPopulation ≥50 years old living in Sweden as of 31 December 2005 with a first hip fracture the years 2006-12.Participants116,111 patients with an incident hip fracture from a closed nationwide cohort.Main outcome measureDeath within 30 days of hospital discharge in relation to hospital length of stay after adjustment for multiple covariates.ResultsMean inpatient length of stay after a hip fracture decreased from 14.2 days in 2006 to 11.6 days in 2012 (P<0.001). The association between length of stay and risk of death after discharge was non-linear (P<0.001), with a threshold for this non-linear effect of about 10 days. Thus, for patients with length of stay of ≤10 days (n=59,154), each 1-day reduction in length of stay increased the odds of death within 30 days of discharge by 8% in 2006 (odds ratio 1.08 (95% confidence interval 1.04 to 1.12)), which increased to16% in 2012 (odds ratio 1.16 (1.12 to 1.20)). In contrast, for patients with a length of stay of ≥11 days (n=56,957), a 1-day reduction in length of stay was not associated with an increased risk of death after discharge during any of the years of follow up.LimitationsNo accurate evaluation of the underlying cause of death could be performed.ConclusionShorter length of stay in hospital after hip fracture is associated with increased risk of death after hospital discharge, but only among patients with length of stay of 10 days or less. This association remained robust over consecutive years.

Project description:IntroductionThe outcome following major arthroplasty surgeries in patients with ankylosing spondylitis (AS) has tremendously improved over the past decades, due to substantial amelioration in the medical therapies and sophistication of available surgical modalities. Although various studies have already demonstrated the complication rates and challenges faced in AS patients undergoing THA, there is a substantial paucity of data on the actual healthcare burden associated with this disease, and the diverse factors which may affect it.MethodsUsing the National Inpatient Sample (NIS) database (on the basis of ICD-10 CMP codes), patients undergoing THA between the years 2016 and 2019 were identified. These patients were then classified into two categories: group A: patients with a known diagnosis of AS; and group N: those without. The details regarding demographical information, associated co-morbidities, data pertaining to patients' hospital admissions including expenditure incurred, length of stay and complications encountered, were compared. In addition, propensity-score matching was performed to identify a 1:1 matched sample of THA patients without AS.ResultsOverall, 367,890 patients underwent THA; among whom, 501 (0.14%) were known AS patients (group A). Group A included a substantially higher proportion of patients belonging to younger age group (58.6 ± 13.4 versus 65.9 ± 11.4 years; p < 0.001), male sex (67.1% in group A vs 44.1% in group N; p < 0.001), and Asian ethnicity (p < 0.001). Group A patients had a substantially higher risk for longer duration of hospital stay (p < 0.03) and higher overall healthcare expenditure incurred (p < 0.001). As compared to group N, AS patients had a significantly higher risk for developing post-operative anemia [21.8% (group A) vs 11.8% (group N); p < 0.02]; and higher rate of periprosthetic infections [2.4% (group A) vs 1.0% (group N); p < 0.007].ConclusionPatients with AS require a significantly longer duration of hospital stay and higher admission-related expenditure following THA, as compared to the general population. These enhanced early health care-associated costs can be attributed to higher complication rates in AS patients. AS patients are prone to higher rates of anemia and peri-prosthetic infections during the early post-THA period.

Project description:BackgroundOperative fixation of ankle fractures is common. However, as reimbursement plans evolve with the potential for bundled payments, it is critical that orthopedic surgeons better understand factors influencing the postoperative length of stay (LOS) in patients undergoing these procedures to negotiate appropriate reimbursement. We sought to identify factors influencing the postoperative LOS in patients with operatively treated ankle fractures.Materials and methodsSix hundred twenty-two patients with ankle fractures between January 1st, 2004 and December 31st, 2010 were identified retrospectively. Charts were reviewed for gender, length of operative procedure, method of fixation, American Society of Anesthesiologists (ASA) physical status score, medical comorbidities, and postoperative LOS. Both univariate and multivariate models were developed to determine predictors of patient LOS. Financial data for an average 24-h inpatient stay were obtained from financial services.ResultsSix hundred twenty-two patients were included. In a linear regression analysis, a statistically significant relationship was demonstrated between ASA status and LOS (P < 0.001). Multiple regression analysis further characterized the relationship between ASA and LOS: a 1-U increase in ASA classification conferred a 3.42-day increase in LOS on average (P < 0.001). Based on an average per-day inpatient cost of $4,503, each unit increase in ASA status led to a $15,490 increase in cost.ConclusionsOur study demonstrates that ASA status is a powerful predictor of LOS in patients undergoing operative fixation of ankle fractures. More complete understanding of these factors will lead to better risk adjustment models for measuring outcomes, determining fair reimbursement, and potential improvements to the efficiency of patient care.Level of evidenceLevel III retrospective comparative study regressing length of stay with many variables, including ASA physical status.

Project description:BackgroundThe steady rise in demand for total hip arthroplasty constitutes a significant and increasing burden on health care resources. The biggest contributors to the total cost of hip replacement procedures other than the price of the implant are hospital stay and postoperative rehabilitation. Blood management is one of the most adjustable factors that can impact length of stay and cost-efficiency while improving patient safety.Questions/purposesThe primary purpose of this retrospective study was to assess the potential impact of blood management interventions on length of hospital stay after primary unilateral total hip arthroplasty. This was achieved by first identifying which patient and surgical factors are associated with an increased risk of prolonged hospital stay. Subsequently, the significant factors were controlled for through a multivariate regression analysis to quantify the association between blood transfusions and increased hospital stay.MethodsRetrospectively, the study included 2,104 primary total hip replacements. Eight hundred eighty-eight procedures were performed on males and 1,216 on females, with a mean age of 64 years at the time of the surgery (range 18-94 years) and BMI of 28.6 kg/m(2) (range 12-51.5 kg/m(2)). The correlation between each factor and length of stay was analyzed separately using univariate regression analysis. Those variables with p ≤ 0.05 in the univariate model were selected for inclusion in the multivariate logistic regressions. Multiple linear regression was used to analyze the effect of each significant factor and derive odds ratios with adjustment for the other variables.ResultsMultivariate Poisson regression revealed that increased length of stay was significantly correlated to patient age (p = 0.05), the use of coumadin (p = 0.02) or lovenox/heparin (p = 0.007) as opposed to aspirin for anticoagulation, and allogeneic blood transfusion (p < 0.0001). The data shows that allogeneic blood transfusion is associated with a longer hospital stay regardless of absolute drop in hemoglobin level postoperatively or at discharge or the number of units transfused (OR = 1.18, 95% CI = 1.09 to 1.28, p < 0.001).ConclusionTransfusion of allogeneic blood is independently associated with increased hospital stay after total hip arthroplasty. Blood management modalities that can significantly reduce transfusion risk could impact length of stay as well as the total cost of hip replacement procedures.

Project description:BackgroundPrior retrospective studies suggest that statins may benefit patients with community-acquired pneumonia (CAP) due to antiinflammatory and immunomodulatory effects. However, prospective studies of the impact of statins on CAP outcomes are needed. We determined whether statin use was associated with improved outcomes in adults hospitalized with CAP.MethodsAdults aged ≥18 years hospitalized with CAP were prospectively enrolled at 3 hospitals in Chicago, Illinois, and 2 hospitals in Nashville, Tennessee, from January 2010-June 2012. Adults receiving statins before and throughout hospitalization (statin users) were compared with those who did not receive statins (nonusers). Proportional subdistribution hazards models were used to examine the association between statin use and hospital length of stay (LOS). In-hospital mortality was a secondary outcome. We also compared groups matched on propensity score.ResultsOf 2016 adults enrolled, 483 (24%) were statin users; 1533 (76%) were nonusers. Statin users were significantly older, had more comorbidities, had more years of education, and were more likely to have health insurance than nonusers. Multivariable regression demonstrated that statin users and nonusers had similar LOS (adjusted hazard ratio [HR], 0.99; 95% confidence interval [CI], .88-1.12), as did those in the propensity-matched groups (HR, 1.03; 95% CI, .88-1.21). No significant associations were found between statin use and LOS or in-hospital mortality, even when stratified by pneumonia severity.ConclusionsIn a large prospective study of adults hospitalized with CAP, we found no evidence to suggest that statin use before and during hospitalization improved LOS or in-hospital mortality.

Project description:ObjectivesTo determine if hospital arthroplasty volume affects patient outcomes after undergoing total hip arthroplasty (THA) for displaced femoral neck fractures.MethodsThe Statewide Planning and Research Cooperative System database from the New York State Department of Health was used to group hospitals into quartiles based on overall THA volume from 2000 to 2010. The database was then queried to identify all patients undergoing THA specifically for femoral neck fracture during this time period. The data were analyzed to investigate outcomes between the 4 volume quartiles in 30-day and 1-year mortality, 1-year revision rate, and 90-day complication rate (readmission for dislocation, deep vein thrombosis, pulmonary embolism, prosthetic joint infection, or other complications related to arthroplasty in the treatment of femoral neck fractures with THA).ResultsPatients undergoing THA for femoral neck fracture at hospitals in the top volume quartile had significantly lower 30-day (0.9%) and 1-year (7.51%) mortality than all other volume quartiles. There were no significant differences on pairwise comparisons between the second, third, and fourth quartiles with regard to postoperative mortality. There was no significant difference in revision arthroplasty at 1 year between any of the volume quartiles. On Cox regression analysis, THA for fracture at the lowest volume (fourth) quartile [hazard ratio (HR), 1.91; P = 0.016, 95% confidence interval (CI), (1.13-3.25)], second lowest volume (third) quartile (HR, 2.01; P = 0.013, 95% CI, 1.16-3.5) and third lowest volume (second) quartile (HR, 2.13; P = 0.005, 95% CI, 1.26-3.62) were associated with increased risk for a 1-year postoperative mortality event. Hospital volume quartile was also a significant risk factor for increased 90-day complication (pulmonary embolism/deep vein thrombosis, acute dislocation, prosthetic joint infection) following THA for femoral neck fracture. Having surgery in the fourth quartile (HR, 2.71; P < 0.001, 95% CI, 1.7-4.31), third quartile (HR, 2.61; P < 0.001, 95% CI, 1.61-4.23), and second quartile (HR, 2.41; P < 0.001, 95% CI, 1.51-3.84), all were significant risk factors for increased 90-day complication risk.ConclusionsThe results of this population-based study indicate that THA for femoral neck fractures at high-volume arthroplasty centers is associated with lower mortality and 90-day complication rates but does not influence 1-year revision rate. THA for femoral neck fractures at top arthroplasty volume quartile hospitals are performed on healthier patients more quickly. Patient health is a critical factor that influences mortality outcomes following THA for femoral neck fractures.Level of evidencePrognostic Level II.

Project description:Background: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are cost-effective procedures that decrease pain and improve health-related quality of life for patients with advanced symptomatic arthritis, including rheumatoid arthritis (RA). Patients with RA have a longer length of stay (LOS) after THA or TKA than patients with osteoarthritis, yet the factors contributing to LOS have not been investigated. Purpose: We sought to identify the factors contributing to LOS for patients with RA undergoing THA and TKA at a single tertiary care orthopedic specialty hospital. Methods: We retrospectively reviewed data from a prospectively collected cohort of 252 RA patients undergoing either THA or TKA. Demographics, RA characteristics, medications, serologies, and disease activity were collected preoperatively. Linear regression was performed to explore the relationship between LOS (log-transformed) and possible predictors. A multivariate model was constructed through backward selection using significant predictors from a univariate analysis. Results: Of the 252 patients with RA, 83% were women; they had a median disease duration of 14 years and moderate disease activity at the time of arthroplasty. We had LOS data on 240 (95%) of the cases. The mean LOS was 3.4 ± 1.5 days. The multivariate analysis revealed a longer LOS for RA patients who underwent TKA versus THA, were women versus men, required a blood transfusion, and took preoperative opioids. Conclusion: Our retrospective study found that increased postoperative LOS in RA patients undergoing THA or TKA was associated with factors both non-modifiable (type of surgery, sex) and modifiable (postoperative blood transfusion, preoperative opioid use). These findings suggest that preoperative optimization of the patient with RA might focus on improving anemia and reducing opioid use in efforts to shorten LOS. More rigorous study is warranted.

Project description:The aim of our study was to determine the association between admitting service, medicine or orthopaedics, and length of stay (LOS) for a geriatric hip fracture patient.Retrospective.Urban level 1 trauma center.Six hundred fourteen geriatric hip fracture patients from 2000 to 2009.Orthopaedic surgery for geriatric hip fracture.Patient demographics, medical comorbidities, hospitalization length, and admitting service. Negative binomial regression used to determine association between LOS and admitting service.Six hundred fourteen geriatric hip fracture patients were included in the analysis, of whom 49.2% of patients (n = 302) were admitted to the orthopaedic service and 50.8% (3 = 312) to the medicine service. The median LOS for patients admitted to orthopaedics was 4.5 days compared with 7 days for patients admitted to medicine (P < 0.0001). Readmission was also significantly higher for patients admitted to medicine (n = 92, 29.8%) than for those admitted to orthopaedics (n = 70, 23.1%). After controlling for important patient factors, it was determined that medicine patients are expected to stay about 1.5 times (incidence rate ratio: 1.48, P < 0.0001) longer in the hospital than orthopaedic patients.This is the largest study to demonstrate that admission to the medicine service compared with the orthopaedic service increases a geriatric hip fractures patient's expected LOS. Since LOS is a major driver of cost as well as a measure of quality care, it is important to understand the factors that lead to a longer hospital stay to better allocate hospital resources. Based on the results from our institution, orthopaedic surgeons should be aware that admission to medicine might increase a patient's expected LOS.Therapeutic Level III.
