Use of osteoporosis medications after hospitalization for hip fracture: a cross-national study.

ABSTRACT: Although current osteoporosis management guidelines recommend use of pharmacologic treatment after hip fracture, the care of such patients has been suboptimal. The objective of this cross-national study was to quantify the use of and adherence to osteoporosis medication after hip fracture in 3 countries with different healthcare systems—the United States, Korea, and Spain.In 3 cohorts of patients aged ?65 years hospitalized for hip fracture, we calculated the proportion receiving ?1 osteoporosis drug after discharge. Adherence to osteoporosis treatment was measured as the proportion of days covered (PDC) during the first year after the hip fracture.We identified 86,202 patients with a hip fracture: 4704 (US Medicare), 6700 (US commercial), 57,631 (Korea), and 17,167 (Spain). The mean age was 77-83 years, and 74%-78% were women. In the year before the index hip fracture, 16%-18% were taking an osteoporosis medication. Within 3 months after the index hip fracture, 11% (US Medicare), 13% (US commercial), 39% (Korea), and 25% (Spain) of patients filled ?1 prescription for osteoporosis medication. For those who filled ?1 prescriptions for an osteoporosis medication, the mean PDC in the year after the fracture was 0.70 (US Medicare), 0.67 (US commercial), 0.43 (Korea), and 0.66 (Spain).Regardless of differences in healthcare delivery systems and medication reimbursement plans, the use of osteoporosis medications for the secondary prevention of osteoporotic fracture was low. Adherence to osteoporosis treatment was also suboptimal, with the PDC <0.70 in all 3 countries.

Project description:Frailty is common in older adults with fractures. Osteoporosis medications reduce subsequent fracture, but limited data exist on medication efficacy in frail individuals. Our objective was to determine whether medications reduce the risk of subsequent fracture in frail, older adults. A retrospective cohort of Medicare fee-for-service beneficiaries was conducted (2014-2016). We included adults aged ≥65 years who were hospitalized with fractures without osteoporosis treatment. Pre-fracture frailty was defined using claims-based frailty index (≥0.2 = frail). Exposure to any osteoporosis treatment (oral or intravenous bisphosphonates, denosumab, and teriparatide) was ascertained using Part B and D claims and categorized according to the cumulative duration of exposure: none, 1-90 days, and >90 days. Subsequent fractures were ascertained from Part A or B claims. Cause-specific hazard models with time-varying exposure were fit to examine the association between treatment and fracture outcomes, controlling for relevant covariates. Among 29,904 patients hospitalized with fractures, 15,345 (51.3%) were frail, and 2148 (7.2%) received osteoporosis treatment (median treatment duration 183.0 days). Patients who received treatment were younger (80.2 versus 82.2 years), female (86.5% versus 73.0%), and less frail (0.20 versus 0.22) than patients without treatment. During follow-up, 5079 (17.0%) patients experienced a subsequent fracture. Treatment with osteoporosis medications for >90 days compared with no treatment reduced the risk of fracture (hazard ratio [HR] = 0.82; 95% confidence interval [CI] 0.68-1.00) overall. Results were similar in frail (HR = 0.85; 95% CI 0.65-1.12) and non-frail (HR = 0.80; 95% CI 0.61-1.04) patients but not significant. In conclusion, osteoporosis treatment >90 days was associated with similar trends in reduced risk of subsequent fracture in frail and non-frail persons. Treatment rates were very low, particularly among the frail. When weighing treatment options in frail older adults with hospitalized fractures, clinicians should be aware that drug therapy does not appear to lose its efficacy. © 2022 American Society for Bone and Mineral Research (ASBMR).

Project description:BackgroundHip fractures are a common and serious consequence of osteoporosis, and hip fracture patients are at high risk for recurrence. Appropriate pharmacotherapy reduces this risk and is associated with reduced mortality after hip fracture, but a care gap exists for fracture prevention in these patients. This evaluation determined rates of osteoporosis treatment and bone mineral density (BMD) testing in hip fracture patients following discharge from a rehabilitation unit.MethodsA prospective cohort study of hip fracture patients aged ? 50 on an inpatient rehabilitation unit in 2008 and 2011. Patients were seen by a nurse specialist, and encouraged to see their family physician for further assessment and treatment. Physicians were sent a letter indicating the need to follow up with their patient. Patients were contacted following discharge from hospital to determine treatment rates.ResultsOf 310 eligible hip fracture patients admitted to the rehabilitation unit in the years studied, 207 patients were reached post-discharge and provided data. Of patients who were not previously taking osteoporosis medication, 59% of patients from the 2008 cohort, and 42% of patients from the 2011 cohort had osteoporosis treatment initiated by six months following discharge. By 2 months following discharge, 46% of patients in the 2008 cohort had a new BMD performed or scheduled, while this was true for 14% of patients from the 2011 cohort. 35% of patients in 2011 had not seen their family physician by 2 months following discharge.ConclusionsRates for osteoporosis treatment and BMD testing were higher than those reported in the literature for patients not enrolled in case manager programs. BMD testing declined from 2008 to 2011. Lower treatment rates may be due to concerns regarding reports of possible association between bisphosphonate use and atypical fractures. Improving rates of patient follow-up with family physicians will be important for increasing hip fracture treatment rates after discharge.

Project description:This population-based study analyzes hip fracture and osteoporosis treatment rates among older adults, stratified by place of residence prior to fracture. Hip fracture rates were higher among older adults living in the community and discharged to long-term care (LTC) after fracture, compared to LTC residents and older adults living in the community. Only 23% of LTC residents at high fracture risk received osteoporosis treatment.PurposeThis population-based study examines hip fracture rate and osteoporosis management among long-term care (LTC) residents > 65 years of age compared to community-dwelling older adults at the time of fracture and admitted to LTC after fracture, in Ontario, Canada.MethodsHealthcare utilization and administrative databases were linked using unique, encoded identifiers from the ICES Data Repository to estimate hip fractures (identified using the Public Health Agency of Canada algorithm and International Classification of Diseases (ICD)-10 codes) and osteoporosis management (pharmacotherapy) among adults > 66 years from April 1, 2014 to March 31, 2018. Sex-specific and age-standardized rates were compared by pre-fracture residency and discharge location (i.e., LTC to LTC, community to LTC, or community to community). Fracture risk was determined using the Fracture Risk Scale (FRS).ResultsAt baseline (2014/15), the overall age-standardized hip fracture rate among LTC residents was 223 per 10,000 person-years (173 per 10,000 females and 157 per 10,000 males), 509 per 10,000 person-years (468 per 10,000 females and 320 per 10,000 males) among the community to LTC cohort, and 31.5 per 10,000 person-years (43.1 per 10,000 females and 25.6 per 10,000 males). During the 5-year observation period, the overall annual average percent change (APC) for hip fracture increased significantly in LTC (AAPC = + 8.6 (95% CI 5.0 to 12.3; p = 0.004) compared to the community to LTC group (AAPC = + 2.5 (95% CI - 3.0 to 8.2; p = 0.248)) and the community-to-community cohort (AAPC - 3.8 (95% CI - 6.7 to - 0.7; p = 030)). However, hip fracture rate remained higher in the community to LTC group over the study period. There were 33,594 LTC residents identified as high risk of fracture (FRS score 4 +), of which 7777 were on treatment (23.3%).ConclusionOverall, hip fracture rates have increased in LTC and among community-dwelling adults admitted to LTC after fracture. However, hip fracture rates among community-dwelling adults have decreased over time. A non-significant increase in osteoporosis treatment rates was observed among LTC residents at high risk of fracture (FRS4 +). Residents in LTC are at very high risk for fracture and require individualized based on goals of care and life expectancy.

Project description:ObjectivesTo determine whether the use of total hip arthroplasty (THA) among individuals with a displaced intracapsular fracture of the femoral neck is based on national guidelines or if there are systematic inequalities.DesignObservational cohort study using the National Hip Fracture Database (NHFD).SettingAll hospitals that treat adults with hip fractures in England, Wales, and Northern Ireland.ParticipantsPatients within the national database (all aged ≥60) who received operative treatment for a non-pathological displaced intracapsular hip fracture from 1 July 2011 to 31 April 2015.Main outcome measuresProvision of THA to patients considered eligible under criteria published by the National Institute for Health and Care Excellence (NICE).Results114 119 patients with hip fracture were included, 11 683 (10.2%) of whom underwent THA. Of those who satisfied the NICE criteria, 32% (6780) : received a THA. Of patients who underwent THA, 42% (4903) did not satisfy the NICE criteria. A recursive partitioning algorithm found that the NICE eligibility criteria did not optimally explain which patients underwent THA. A model with superior explanatory power drew distinctions that are not supported by NICE, which were an age cut off at 76 and a different ambulation cut off. Among patients who satisfied the NICE eligibility, the use of THA was less likely with higher age (odds ratio 0.88, 95% confidence interval 0.87 to 0.88), worsening abbreviated mental test scores (0.49 (0.41 to 0.58) for normal cognition v borderline cognitive impairment)), worsening American Society of Anesthesiologists score (0.74, 0.66 to 0.84), male sex (0.85, 0.77 to 0.93), worsening ambulatory status (0.32, 0.28 to 0.35 for walking with a stick v independent ambulation), and fifths of worsening socioeconomic area deprivation (0.76 (0.66 to 0.88) for least v most deprived fifth). Patients receiving treatment during the working week were more likely to receive THA than at the weekend (0.90, 0.83 to 0.98).ConclusionsThere are wide disparities in the use of THA among individuals with hip fractures, and compliance with NICE guidance is poor. Patients with higher levels of socioeconomic deprivation and those who require surgery at the weekend were less likely to receive THA. Inconsistent compliance with NICE recommendations means that the optimal treatment for older adults with hip fractures can depend on where and when they present to hospital.

Project description:ImportanceOsteoporosis medication treatment is recommended after hip fracture, yet contemporary estimates of rates of initiation and clinical benefit in the patient population receiving routine care are not well documented.ObjectivesTo report osteoporosis treatment initiation rates between January 1, 2004, and September 30, 2015, and to estimate the risk reduction in subsequent nonvertebral fractures associated with treatment initiation in patients with hip fracture.Design, setting, and participantsIn this cohort study, data from a commercial insurance claims database from the United States were analyzed. Patients 50 years and older who had a hip fracture and were not receiving treatment with osteoporosis medications before their fracture were included.ExposurePrescription dispensing of an osteoporosis medication within 180 days of a hip fracture hospitalization.Main outcomes and measuresEach initiation episode was matched with 10 nonuse episodes on person-time after the index hip fracture event to preclude immortal time bias and followed up for the outcome of nonvertebral fracture until change in exposure or a censoring event. An instrumental variable analysis using 2-stage residual inclusion method was conducted using calendar year, specialist access, geographical variation in prescribing patterns, and hospital preference.ResultsAmong 97 169 patients with a hip fracture identified, the mean (SD) age was 80.2 (10.8) years, and 64 164 (66.0%) were women. A continuous decline over the study years was observed in osteoporosis medication initiation rates from 9.8% (95% CI, 9.0%-10.6%) in 2004 to 3.3% (95% CI, 2.9%-3.8%) in 2015. In the effectiveness analyses, the hospital preference instrumental variable had a stronger association with treatment (pseudo R2 = 0.20) than the other 3 instrumental variables (specialist access: pseudo R2 = 0.04; calendar year: pseudo R2 = 0.05; and geographic variation: pseudo R2 = 0.07). Instrumental variable analysis with hospital preference suggested a rate difference of 4.2 events (95% CI, 1.1-7.3) per 100 person-years in subsequent fractures associated with osteoporosis treatment initiation compared with nonuse in an additive hazard model.Conclusions and relevanceLow rates of osteoporosis treatment initiation after a hip fracture in recent years were observed. Clinically meaningful reduction in subsequent nonvertebral fracture rates associated with treatment suggests that improving prescriber adherence to guidelines and patient adherence to prescribed regimens may result in notable public health benefit.
