Claims-based Identification Methods and the Cost of Fall-related Injuries Among US Older Adults.

ABSTRACT: OBJECTIVES:Compare expenditures of fall-related injuries (FRIs) using several methods to identify FRIs in administrative claims data. RESEARCH DESIGN:Using 2007-2009 Medicare claims and 2008 Health and Retirement Survey data, FRIs were identified using external-cause-of-injury (e-codes 880/881/882/884/885/888) only, e-codes plus a broad set of primary diagnosis codes, and a newer approach using e-codes and diagnostic and procedural codes. Linear regression models adjusted for sociodemographic, health, and geographic characteristics were used to estimate per-FRI, service component, patient cost share, expenditures by type of initial FRI treatment (inpatient, emergency department only, outpatient), and total annual FRI-related Medicare expenditures. SUBJECTS:The analysis included 5497 community-dwelling adults ?65 (228 FRI, 5269 non-FRI individuals) with continuous Medicare coverage and alive during the 24-month study. RESULTS:The 3 FRI identification methods produced differing distributions of index FRI type and varying estimated expenditures: $12,171 [95% confidence interval (CI), $4662-$19,680], $5648 (95% CI, $3819-$7476), and $9388 (95% CI, $5969-$12,808). In all models, most spending occurred in hospital, outpatient, and skilled nursing facility (SNF) settings, but greater proportions of SNF and outpatient spending were observed with commonly used FRI identification methods. Patient cost-sharing was estimated at $691-$1900 across the 3 methods. Inpatient-treated index FRIs were more expensive than emergency department and outpatient-treated FRIs across all methods, but were substantially higher when identifying FRI using only e-codes. Estimated total FRI-related Medicare expenditures were highly variable across methods. CONCLUSIONS:FRIs are costly, with implications for Medicare and its beneficiaries. However, expenditure estimates vary considerably based on the method used to identify FRIs.

Project description:ImportanceTo date, measurement and treatment of older adult fall injury has been siloed within specific care settings, such as a hospital or within a nursing home or community. Little is known about changes in fall risk across care settings. Understanding the occurrence of falls across settings has implications for measuring and incentivizing high-value care across care settings.ObjectiveTo estimate the risk of older adult fall injury within and across discrete periods during a 12-month care episode anchored by an acute hospitalization.Design, setting, and participantsThis cohort study is a longitudinal analysis of 12-month periods that include an anchor hospital stay using national data from 2006 to 2014. Participants included older (aged ≥65 years) Medicare fee-for-service beneficiaries from the Health and Retirement Study. Weekly fall injury rates were computed for 4 periods compared with the anchor hospitalization: at baseline (1-6 months before hospitalization), just before (<1 month before hospitalization), just after (<1 month after hospitalization), and at follow-up (1-6 months after hospitalization). Piecewise logistic regression models estimated weekly marginal risk of fall injury within each period, adjusting for sociodemographic and health characteristics. Fall injury risks for high-risk beneficiaries with a fall injury during the anchor hospitalization were also estimated. Data analysis was performed from November 2019 to April 2020.Main outcomes and measuresFall injuries.ResultsIn total, 10 106 anchor hospitalizations for 4101 beneficiaries (mean [SD] age, 77.1 [7.6] years; 5912 hospitalizations among women [58.5%]) were identified. The overall fall injury risk was 0.77%. In adjusted models, marginal increases in weekly fall injury risk just before hospitalization (0.27 percentage points [95% CI, 0.22 to 0.33 percentage points], or 30.0%; P < .001) were 4 times greater than decreases just after hospitalization (-0.18 percentage points [95% CI, -0.23 to -0.13 percentage points], or -9.2%; P < .001)]. A greater risk differential before and after hospitalization was observed for patients with an inpatient fall injury (1.89 percentage points [95% CI, 1.37 to 2.40], or 309.8%; P < .001; vs -0.39 percentage points [95% CI, -0.73 to -0.04], or -11.6%; P = .03).Conclusions and relevanceAn episode-based assessment of fall injury illustrates substantial variability in period-specific risks over an extended period including an anchor hospitalization. Risk transitions between periods include sizable increases just before hospitalization that do not fully subside after hospital discharge. Financial incentives to coordinate hospital and posthospital care for patients at risk for fall injury are needed. These could include bundled payments for fall injury episodes that incentivize coordination across settings.

Project description:BackgroundCompliant flooring, broadly defined as flooring systems or floor coverings with some level of shock absorbency, may reduce the incidence and severity of fall-related injuries in older adults; however, a lack of synthesized evidence may be limiting widespread uptake.MethodsInformed by the Arksey and O'Malley framework and guided by a Research Advisory Panel of knowledge users, we conducted a scoping review to answer: what is presented about the biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety associated with compliant flooring systems that aim to prevent fall-related injuries in healthcare settings? We searched academic and grey literature databases. Any record that discussed a compliant flooring system and at least one of biomechanical efficacy, clinical effectiveness, cost-effectiveness, or workplace safety was eligible for inclusion. Two independent reviewers screened and abstracted records, charted data, and summarized results.ResultsAfter screening 3611 titles and abstracts and 166 full-text articles, we included 84 records plus 56 companion (supplementary) reports. Biomechanical efficacy records (n = 50) demonstrate compliant flooring can reduce fall-related impact forces with minimal effects on standing and walking balance. Clinical effectiveness records (n = 20) suggest that compliant flooring may reduce injuries, but may increase risk for falls. Preliminary evidence suggests that compliant flooring may be a cost-effective strategy (n = 12), but may also result in increased physical demands for healthcare workers (n = 17).ConclusionsIn summary, compliant flooring is a promising strategy for preventing fall-related injuries from a biomechanical perspective. Additional research is warranted to confirm whether compliant flooring (i) prevents fall-related injuries in real-world settings, (ii) is a cost-effective intervention strategy, and (iii) can be installed without negatively impacting workplace safety. Avenues for future research are provided, which will help to determine whether compliant flooring is recommended in healthcare environments.

Project description:BackgroundMedications influencing the risk of fall-related injuries (FRIs) in older adults have been inconsistent in previous guidelines. This study employed case-control design to assess the association between FRIs and medications, and an additional case-crossover design was conducted to examine the consistency of the associations and the transient effects of the medications on FRIs.MethodsThis study was conducted using a national claims database (2002-2015) in Korea. Older adults (≥ 65 years) who had their first FRI between 2007 and 2015 were matched with non-cases in 1:2 ratio. Drug exposure was examined for 60 days prior to the date of the first FRI (index date) in the case-control design. The hazard period (1-60 days) and two control periods (121-180 and 181-240 days prior to the index date) were investigated in the case-crossover design. The risk of FRIs with 32 medications was examined using conditional logistic regression after adjusting for other medications that were significant in the univariate analysis. In the case-crossover study, the same conditional model was applied.ResultsIn the case-control design, the five medications associated with the highest risk of FRIs were muscle relaxants (adjusted odd ratio(AOR) = 1.35, 95% confidence interval (CI) = 1.31-1.39), anti-Parkinson agents (AOR = 1.30, 95%CI = 1.19-1.40), opioids (AOR = 1.23, 95%CI = 1.19-1.27), antiepileptics (AOR = 1.19, 95%CI = 1.12-1.26), and antipsychotics (AOR = 1.16, 95%CI = 1.06-1.27). In the case-crossover design, the five medications associated with the highest risk of FRIs were angiotensin II antagonists (AOR = 1.87, 95%CI = 1.77-1.97), antipsychotics (AOR = 1.63, 95%CI = 1.42-1.83), anti-Parkinson agents (AOR = 1.58, 95%CI = 1.32-1.85), muscle relaxants (AOR = 1.42, 95%CI = 1.35-1.48), and opioids (AOR = 1.35, 95%CI = 1.30-1.39).ConclusionsAnti-Parkinson agents, opioids, antiepileptics, antipsychotics, antidepressants, hypnotics and sedatives, anxiolytics, muscle relaxants, and NSAIDs/antirheumatic agents increased the risk of FRIs in both designs among older adults. Medications with a significant risk only in the case-crossover analysis, such as antithrombotic agents, calcium channel blockers, angiotensin II antagonists, lipid modifying agents, and benign prostatic hypertrophy agents, may have transient effects on FRIs at the time of initiation. Corticosteroids, which were only associated with risk of FRIs in the case-control analysis, had more of cumulative than transient effects on FRIs.

Project description:BackgroundPotentially inappropriate medications (PIMs) are prevalent in older adults with dementia and subsequent falls or fall-related injuries. The present study determined the risk of falls or fall-related injuries associated with PIM use in older adults with dementia.MethodsThe National Health Insurance Service-Elderly Cohort Database 2.0 (NHIS-ECDB 2.0) was used for this self-controlled case series (SCCS) study. This study included 1430 participants who went through exposure and non-exposure periods of PIM application among patients with dementia and experienced outcome events of falls or fall-related injuries between January 2016 and December 2019. The incidence of falls or fall-related injuries during the exposure and post-exposure periods was compared with that during the non-exposure period. Beers Criteria were used to define PIMs in patients with dementia. Negative binomial regression was conducted. The incidence rate ratio (IRR) was used to determine the risk of falls or fall-related injuries.ResultsDuring the exposure periods in which falls or fall-related injuries occurred, the mean number of PIMs among patients with dementia was 3.76 (SD = 2.99), and the most commonly used PIMs among patients with dementia were first-generation antihistamines (n = 283; 59.1%). Compared to the non-exposure period, the adjusted IRR during the exposure period was 1.57 (95% CI = 1.39-1.76). The risk of falls or fall-related injuries was increased when PIM use in patients with dementia was initiated (1-14 days: IRR = 2.76, 95% CI = 2.31-3.28; 15-28 days: IRR = 1.95, 95% CI = 1.48-2.56; ≥ 29 days: IRR = 1.17, 95% CI = 1.01-1.35). Especially, an increased risk of falls or fall-related injuries was associated with greater PIM use among patients with dementia.ConclusionAmong older adults with dementia, PIMs significantly increase the risk of falls and fall-related injuries. Therefore, strategies should be developed to manage PIM prescriptions in patients with dementia to prevent falls.

Project description:Importance:Falls are common among older adults, particularly those with previous falls and cognitive impairment and in the postdischarge period. Hospitals have financial incentives to reduce both inpatient falls and hospital readmissions, yet little is known about whether fall-related injuries (FRIs) are common diagnoses for 30-day hospital readmissions. Objective:To compare fall-related readmissions with other leading rehospitalization diagnoses, including for patients at greatest risk of readmission. Design, Setting, and Participants:Retrospective cohort study of the Hospital Cost and Utilization Project's Nationwide Readmissions Database of nationally representative US hospital discharges among Medicare beneficiaries aged 65 years and older from January 1, 2013, to November 30, 2014. The prevalence and ranking of FRIs compared with other diagnostic factors for 30-day unplanned hospital-wide readmissions were determined, overall and for 2 acute geriatric cohorts, classified by fall injury or cognitive impairment diagnoses observed at the index admission. Analyses were also stratified by patient discharge disposition (home, home health care, skilled nursing facility). Analyses were conducted from February 1, 2018, to February 26, 2018. Main Outcomes and Measures:Unplanned hospital-wide readmission within 30 days of discharge. Results:From the database, 8?382?074 eligible index admissions were identified, including 746?397 (8.9%) in the FRI cohort and 1?367?759 (16.3%) in the cognitive impairment cohort. Among the entire 8 382 074-discharge cohort, mean (SD) age was 77.7 (7.8) years and 4?736?281 (56.5%) were female. Overall, 1?205?962 (14.4%) of index admissions resulted in readmission, with readmission rates of 12.9% for those with a previous fall and 16.0% for patients with cognitive impairment. Overall, FRIs ranked as the third-leading readmission diagnosis, accounting for 60?954 (5.1%) of all readmission diagnoses. Within the novel acute geriatric cohorts, FRIs were the second-leading diagnosis for readmission both for patients with an FRI at index admission (10.3% of all readmission diagnoses) and those with cognitive impairment (7.0% of all readmission diagnoses). For those with an FRI at index admission and discharged home or to home health care, FRIs were the leading readmission diagnosis. Conclusions and Relevance:This study found that posthospital FRIs were a leading readmission diagnosis, particularly for patients originally admitted with a FRI or cognitive impairment. Targeting at-risk hospitalized older adults, particularly those discharged to home or home health care, is an underexplored, cost-effective mechanism with potential to reduce readmissions and improve patient care.

Project description:BackgroundDespite increasing numbers of older adults undergoing surgery and the known risks of opioids, little is known about the potential association between opioid prescribing and serious falls and fall-related injuries after surgery.ObjectiveTo determine the incidence and risk factors of serious falls and fall-related injuries after elective, outpatient surgery.DesignRetrospective cohort study of 20% national sample of Medicare claims among beneficiaries ≥ 65 years of age with Medicare Part D claims and who underwent elective outpatient surgery from January 1, 2009, through December 31, 2014.ParticipantsOpioid-naïve patients ≥ 65 years undergoing elective, minor, outpatient surgical procedures. The exposure was opioid prescription fills in the perioperative period (i.e., 30 days before up until 3 days after surgery) converted to total oral morphine equivalents (OME) over a period 30 days prior to and 30 days after surgery.Main measuresSerious falls and fall-related injuries within 30 days after surgery, examined through Poisson regression analysis with reported fall and fall-related injury rates adjusted for potential confounders.Key resultsAmong 44,247 opioid-naïve surgical patients, 76.3% filled an opioid prescription in the perioperative period. Overall, 0.62% of patients suffered a serious fall or fall-related injury within 30 days after surgery. Risk factors for serious falls or fall-related injuries after surgery included older age (80-84 years: RR 1.64, 95% CI 1.12-2.40; 85 years and older: RR 1.81, 95% CI 1.25-2.86), female sex (RR 3.04, 95% CI 2.29-4.05), Medicaid eligibility (RR 1.63, 95% CI 1.17-2.26), and higher amounts of opioids filled following surgery (≥ 225 OME: RR 2.29, 95% CI 1.72-3.07).ConclusionsSerious falls after elective, outpatient surgery are uncommon, but correlated with age, sex, Medicaid eligibility, and the amount of opioids filled in the perioperative period. Judicious prescribing of opioids after surgery is paramount and is an opportunity to improve the safety of surgical care among older individuals.
