Risk factors for opioid-related adverse drug events among older adults after hospitalization for major orthopedic procedures.
The purpose of this retrospective cohort study was to identify risk factors for opioid-related adverse drug events (ORADEs) after hospital discharge following orthopedic procedures. The participants of this study included a national sample of Medicare beneficiaries who underwent major orthopedic surgery during hospitalization in 2016 and had an opioid prescription filled within 2 days of discharge. The study found that among 30,514 hospitalizations with a major orthopedic procedure and an opioid claim, a potential ORADE requiring hospital revisit occurred in 2.5%. After adjustment for patient characteristics, prior opioid use, co-prescribed sedating medications, and opioid prescription characteristics were not related with ORADEs. Independent risk factors did include age of 80 years or older, female sex, and clinical conditions, including heart failure, respiratory illness, kidney disease, dementia/delirium, anxiety disorder, and musculoskeletal/nervous system injuries.

Trajectories of prescription opioid dose and risk of opioid-related adverse events among older Medicare beneficiaries in the United States: a nested case-control study.
This study used a sample of older patients who are Medicare beneficiaries who were newly prescribed opioids to determine rates of 4 prescription opioid dose trajectories and the risk of opioid-related adverse events (ORAEs). A 5% random sample of Medicare beneficiaries from 2011 to 2018 was used to conduct a nested case-control study of patients age 65 and older who were newly diagnosed with chronic noncancer pain (CNCP). Among the cases and controls, 2,192 (70.6%) were women and mean age was 77.1 years. Four prescribed opioid trajectories before the incident ORAE diagnosis or matched date emerged: gradual dose discontinuation (from ≤3 to 0 daily morphine milligram equivalent (MME), 1,456 [23.5%]), gradual dose increase (from 0 to >3 daily MME, 1,878 [30.3%]), consistent low dose (between 3 and 5 daily MME, 1,510 [24.3%]), and consistent moderate dose (>20 daily MME, 1,362 [22.0%]). Less than 5% were prescribed a mean daily dose of ≥90 daily MME during 6 months before diagnosis or matched date. Patients with gradual dose discontinuation versus those with a consistent low or moderate dose, and increase dose were more likely to be 65 to 74 years, Midwest US residents, and receiving no low-income subsidy. Those with gradual dose increase and consistent moderate dose had a higher risk of ORAE, after adjustment for covariates.

Risk factors for opioid-related adverse drug events among older adults after hospital discharge.
This study examined patient- and prescribing-related risk factors for opioid-related adverse drug events (ADEs) after hospital discharge among medical patients. Administrative billing codes and medication claims were used to define potential opioid-related ADEs within 30 days of hospital discharge. Findings showed that potential opioid-related ADEs occurred in 7% of older adults discharged from a medical hospitalization with an opioid prescription. Recommendations included using identified risk factors to inform physician decision-making, having conversations with older adults about risk, and increasing development and targeting of harm reduction strategies.

Relative risks of adverse events among older adults receiving opioids versus NSAIDs after hospital discharge: a nationwide cohort study.
This retrospective cohort study’s objective was to determine the incidence and risk of post-discharge adverse events among opioid claims in the week after hospital discharge, compared to those with nonsteroidal anti-inflammatory drugs (NSAIDs) claims alone. A national sample of Medicare beneficiaries age 65 and older who were hospitalized in the United States in 2016 was used. Beneficiaries who were admitted from or discharged to a facility were excluded. The authors used 3:1 propensity matching to match beneficiaries with an opioid claim in the week after discharge (13,385) with beneficiaries with NSAID claim alone (4,677). Beneficiaries receiving opioids had a higher incidence of death, healthcare utilization, and any potential adverse effect compared to those with an NSAID claim only. Specific adverse effects included higher relative risk of fall/fracture, nausea/vomiting, and slowed colonic motility.

Omissions of care in nursing homes: a uniform definition for research and quality improvement.
The goal of this study was to create a uniform definition of omission of care in US nursing homes. Lack of a uniform definition has made efforts to prevent them challenging. Subject matter experts and a broad range of nursing home stakeholders were brought together in iterative rounds of engagement to identify key concepts and aspects of omissions of care and develop a consensus-based definition. The concise definition decided on was: “Omissions of care in nursing homes encompass situations when care–either clinical or nonclinical–is not provided for a resident and results in additional monitoring or intervention or increases the risk of an undesirable or adverse physical, emotional, or psychosocial outcome for the resident."

Frailty as a predictor of death or new disability after surgery: a prospective cohort study.
The purpose of this study was to compare the accuracy of the modified Fried Index (mFI) and the Clinical Frailty Scale (CFS) to predict death or patient-reported new disability 90 days after major elective surgery. Results showed that older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery and that although accuracy was similar, the CFS, compared to the mFI, was easier to use and feasibility was higher.

Long-term functional decline after high-risk elective colorectal surgery in older adults.
This study examined the long-term risks of functional decline after elective colorectal surgery in older adults. This retrospective matched cohort study used data from the Health and Retirement Study, a nationally representative, longitudinal survey of adults >50 years of age. This survey collected data on functional status, cognition, and demographics, among other topics. The survey was linked with Medicare claims and National Death Index data from 1992 to 2012 and used patients 65 years and older. Surgery patients did experience a greater likelihood of functional decline with or without complications compared to control subjects. The older the patient, the more likelihood of a functional decline occurring after surgery.

Patient and system factors associated with unassisted and injurious falls in hospitals: an observational study.
Unassisted falls are more likely to result in injury than assisted falls. However, little is known about risk factors for falling unassisted. Furthermore, rural hospitals, which care for a high proportion of older adults, are underrepresented in research on hospital falls. This study identified risk factors for unassisted and injurious falls in rural hospitals.

Characteristics of long-term care residents that predict adverse events after hospitalization.
This study examined the characteristics of long-term care (LTC) residents that predict adverse events (AEs) after discharge from recent hospitalization. This cohort study looked at AEs that occurred at 32 nursing homes from six New England states. AE incidents involving a total of 555 LTC residents with 762 transitions from the hospital back to LTC were reviewed. The association between all AEs and preventable AEs developing in the 45 days following discharge back to LTC was measured. There were 283 discharges with one or more AEs and 212 with preventable AEs. Characteristics independently associated with higher risk of AEs included hospital length of stay (LOS) 9 or more days, 18 or more regularly scheduled medications, and 19 and above on the dependency in activities of daily living (ADL) scale.

Development and validation of a pragmatic natural language processing approach to identifying falls in older adults in the emergency department.
This study examined development and validation of a pragmatic natural language processing (NLP) approach to identify fall risk in older adults after emergency department (ED) visits. A single center retrospective review using data from 500 emergency department provider notes on older adults age 65 and older were random selected for analysis. The NLP algorithm successfully identified falls in ED notes with over 90% precision, and looks promising to reduce labor-intensive manual abstraction.

Impact of heart failure type on thromboembolic and bleeding risk in patients with atrial fibrillation on oral anticoagulation.
Differential impact of heart failure (HF) category on thromboembolic and bleeding risk in atrial fibrillation (AF) patients on oral anticoagulation (OAC) is unknown. In this study, the investigators used Medicare data for beneficiaries with new AF diagnosed between 2011 and 2013 to identify patients with HF with reduced ejection fraction (HFrEF), HF with preserved ejection fraction (HFpEF), and no HF. The investigators concluded that in AF patients, HFrEF and HFpEF are both associated with higher risk of ischemic stroke, HF and AMI admissions, even after adjusting for OAC use, compared with patients without HF.

Bleeding and thromboembolism after traumatic brain injury in the elderly: a real conundrum.
The objectives of this study were to evaluate the incidence of bleeding, recurrent traumatic brain injury (TBI), and thromboembolic (TE) events after an initial TBI in older adults and to identify which factors contribute to this risk. The researchers found that, among Medicare patients hospitalized with TBI, the incidence of TE events was significantly higher than that of bleeding or recurrent TBI. They identified specific risk factors of bleeding and TE events, which may guide care of older adults after TBI.

Fall risk, supports and services, and falls following a nursing home discharge.
The purpose of this study was to examine whether the presence of supports and services have an impact on the relationship between fall-related risk factors and fall occurrence following a nursing-home discharge. The study sample was comprised of 1459 participants in the Minnesota Return to Community Initiative, who had been assisted in achieving a community discharge; 15 percent of participants fell within 30 days of nursing-home discharge. A structural equation model was used to determine relationship between emerging latent variables and falls. Results indicated that use of high-risk medications and fall concerns/history had a direct, positive effect on falling. Receiving supports/services did not have a direct effect on falls, but the authors note that it reduced the effect of high-risk medication use on falling.

Using the Hendrich II Inpatient Fall Risk Screen to predict outpatient falls after emergency department visits.
This study examined the utility of using the Hendrich II Inpatient Fall Risk Screen to predict outpatient falls in elderly patients after emergency department (ED) visits. Individuals aged 65 and older seen in the ED from January 2013 to September 30, 2015 participated in the study. The Hendrich II screen was found to correlate with outpatient falls, but it is likely it would have little utility as a stand-alone fall screen. When the screen was combined with other potential confounders or predictors, the screen performed much better.

Use of hematopoietic growth factors and risk of thromboembolic and pulmonary toxicities in elderly patients with advanced ovarian cancer.
This study evaluated the risk of thromboembolic and pulmonary toxicities associated with hematopoietic growth factor (HGF) use (i.e., erythropoietin-stimulating agent [ESA] and/or colony-stimulating factor [CSF]) in a community-dwelling cohort of elderly patients with advanced ovarian cancer. An increased risk of thromboembolic events was observed in elderly patients with ovarian cancer who received ESA + CSF.

Colonoscopy and risk of infective endocarditis in the elderly.
The authors estimated the risk of infective endocarditis (IE) after colonoscopy in individuals aged 70 to 79 without a history of colorectal cancer (CRC), endocarditis, or colectomy from a random 20% sample of Medicare beneficiaries. Their findings suggest that individuals without risk factors for IE and those without gastrointestinal symptoms did not have an elevated IE risk after colonoscopy. However, they found a modestly increased risk among individuals with risk factors for IE who undergo a polypectomy or a biopsy during a colonoscopy following recent symptoms.

Bisphosphonates and hip and nontraumatic subtrochanteric femoral fractures in the Veterans Health Administration.
This study examined associations between bisphosphonate use and nontraumatic subtrochanteric (NTST) femoral fractures and hip fractures in the Veterans Health Administration. It found that nontraumatic subtrochanteric femoral fractures were uncommon, and longer bisphosphonate use was associated with lower (not higher) risk. In men, risks of NTST femoral fractures associated with bisphosphonate treatment may be low in contrast to substantial protective benefits for hip fracture.
