Association Between Patient and Facility Characteristics and Rehabilitation Outcomes After Joint Replacement Surgery in Different Rehabilitation Settings for Older Adults: A Systematic Review.

BACKGROUND AND PURPOSE: In the United States, an exponential increase in total hip arthroplasty (THA) and total knee arthroplasty (TKA) demand has occurred over the last 2 decades. Evidence suggesting patients receiving inpatient rehabilitation following a TKA or THA experience similar outcomes as those with rehabilitation in other settings led to dramatic shifts in postsurgical care settings owing to Centers for Medicare & Medicaid Services (CMS) payment reforms. A contemporary synthesis of evidence about the association between patient and facility factors and outcomes from older adults undergoing THA or TKA in the United States is needed. METHODS: To identify eligible studies, we searched PubMed, Scopus, and CINAHL. We followed PRISMA guidelines to identify articles evaluating either patient or facility factors associated with outcomes after THA or TKA for older adults who may have been cared for in inpatient settings (ie, inpatient rehabilitation or skilled nursing facility [SNF]). Eligible articles were conducted in the United States and were published between January 1, 2000, and December 31, 2021. RESULTS: We included 8 articles focused on patient factors and 9 focused on facility factors. Most included older adults and the majority were White (in those reporting race/ethnicity). Most studies evaluated outcomes at discharge and showed that patients admitted to inpatient rehabilitation facilities had either similar or better functional outcomes (mobility, self-care, and functional independence measure (FIM) score) and lower length of stay compared with those in SNFs. Few studies focused on home health care. CONCLUSIONS: The systematic review focused on older adults showed that findings in these patients are consistent with previous research. Older adults undergoing THA/TKA had acceptable outcomes regardless of postsurgical, inpatient setting of care. Research conducted after CMS payment reforms, in home health care settings, and in more diverse samples is needed. Given the known racial/ethnic disparities in THA/TKA and the shifts to postsurgical home health care with little regulatory oversight of care quality, contemporary research on outcomes of postsurgical THA/TKA outcomes is warranted.

Self- and staff-reported pain in relation to contextual isolation in long-term nursing home residents with Alzheimer's disease and related dementias.

We evaluated the degree to which contextual isolation in nursing home residents with Alzheimer's disease and related dementias is associated with documented pain using the Minimum Data Set 3.0, a comprehensive resident assessment required of all nursing home residents in the United States. Contextual isolation was defined as having a socially salient characteristic (demographics, habits and interests, and clinical and care dimensions) shared by fewer than 20% of other residents in the same nursing home. Thirteen percent were contextually isolated on multiple characteristics. Among residents self-reporting pain, residents contextually isolated with respect to multiple characteristics were 8% more likely (95% confidence interval: 7% to 9%) to have pain relative to residents who were not contextually isolated on any characteristics. Long-stay nursing home residents with ADRD who live in settings where they were contextually isolated were more likely to have pain relative to those without contextually isolation on any characteristic.

Antihyperglycemic Drug Use in Long-Stay Nursing Home Residents with Diabetes Mellitus.

Background: About 29.2% of American adults ≥ 65 years of age have diabetes mellitus, but details regarding diabetes management especially among nursing home residents are dated. Objectives: Evaluate the prevalence of antihyperglycemic agents in residents with diabetes mellitus and describe resident characteristics using major drug classes. Design: cross-sectional study. Setting: virtually all United States nursing homes. Participants: 141,636 residents with diabetes mellitus. Measurements: Minimum Data Set (2016) and Medicare Part D claims determined use of metformin, sulfonylureas, meglitinide analogs, alpha-glucosidase inhibitors, TZDs, DPP4 inhibitors, SGLT2 inhibitors, GLP1 agonists, as monotherapy and with basal insulin. Results: Seventy-two percent received antihyperglycemic drugs [most common: basal insulins (53.9% total; 46.9% with other non-insulin agents), metformin (35.5% total; 14.2% monotherapy), sulfonylureas (19.6% total; 6.3% monotherapy), and DPP4 inhibitors (12.2% total; 2.2% monotherapy)]. Sixty-three percent of meglitinide monotherapy versus 34.1% of metformin monotherapy users; and 38.3% meglitinide-basal insulin versus 22.2% metformin-basal insulin users were ≥85 years. Obesity was greater among users of GLP1 agonists compared to those receiving other agents (monotherapy: 60.5% versus 33-42%; with basal insulin: 76.2% versus 50-58%). End-stage renal disease was least prevalent among metformin users (monotherapy: 6.6%; with basal insulin: 8.8%) and most common among meglitinide monotherapy (19.6%) and GLP1 agonists with basal insulin (22%) users. Conclusions: There is heterogeneity of diabetes treatment in nursing homes. Use of antihyperglycemic drugs with a higher risk of hypoglycemia, such as insulin with sulfonylureas or meglitinides, continue in nursing home residents.

Prevalence and treatment of neuropathic pain diagnoses among U.S. nursing home residents.

ABSTRACT: Neuropathic pain is a common condition experienced by older adults. Prevalence estimates of neuropathic pain and descriptive data of pharmacologic management among nursing home residents are unavailable. We estimated the prevalence of neuropathic pain diagnoses and described the use of pain medications among nursing home residents with possible neuropathic pain. Using the Minimum Data Set 3.0 linked to Medicare claims for residents living in a nursing home on November 30, 2016, we included 473,815 residents. ICD-10 codes were used to identify neuropathic pain diagnoses. Identification of prescription analgesics/adjuvants was based on claims for the supply of medications that overlapped with the index date over a 3-month look-back period. The prevalence of neuropathic pain was 14.6%. Among those with neuropathic pain, 19.7% had diabetic neuropathy, 27.3% had back and neck pain with neuropathic involvement, and 25.1% had hereditary or idiopathic neuropathy. Among residents with neuropathic pain, 49.9% received anticonvulsants, 28.6% received antidepressants, 19.0% received opioids, and 28.2% had no claims for analgesics or adjuvants. Resident characteristics associated with lack of medications included advanced age, dependency in activities of daily living, cognitive impairment, and diagnoses of comorbid conditions. A diagnosis of neuropathic pain is common among nursing home residents, yet many lack pharmacologic treatment for their pain. Future epidemiologic studies can help develop a more standard approach to identifying and managing neuropathic pain among nursing home residents.

Methodological Challenges for Epidemiologic Studies of Deprescribing at the End of Life.

PURPOSE OF REVIEW: To describe approaches to measuring deprescribing and associated outcomes in studies of patients approaching end of life (EOL). RECENT FINDINGS: We reviewed studies published through 2020 that evaluated deprescribing in patients with limited life expectancy and approaching EOL. Deprescribing includes reducing the number of medications, decreasing medication dose(s), and eliminating potentially inappropriate medications. Tools such as STOPPFrail, OncPal, and the Unnecessary Drug Use Measure can facilitate deprescribing. Outcome measures vary and selection of measures should align with the operationalized deprescribing definition used by study investigators. SUMMARY: EOL deprescribing considerations include medication appropriateness in the context of patient goals for care, expected benefit from medication given life expectancy, and heightened potential for medication-related harm as death nears. Additional data are needed on how EOL deprescribing impacts patient quality of life, caregiver burden, and out-of-pocket medication-related costs to patients and caregivers. Investigators should design deprescribing studies with this information in mind.

A Latent Approach to Understanding Pain in Nursing Home Residents Who are Unable to Self-Report Pain.

CONTEXT: Pain assessment in people with cognitive impairment is challenging. OBJECTIVE: The study sought to 1) identify pain subgroups based on staff-assessed pain, agitated and reactive behavior, functional status, and symptoms of depression; and 2) understand if cognitive impairment was associated with transitions between pain subgroups at nursing home admission, 3 months, and 6 months. METHODS: Using national Minimum Data Set 3.0 data (2011-2016), we included 26,816 newly admitted residents with staff-assessed pain at admission, 3 months, and 6 months. Pain subgroups were identified by latent class analysis at each time point. Transitions between pain subgroups were described using latent transition analysis. RESULTS: Five latent statuses of pain were identified at admission: "Behavioral and Severe Depression" (prevalence stable, severe or worsening cognitive impairment: 11%, mild/moderate or improved cognitive impairment: 10%), "Functional" (21%; 25%), "Physical" (22%; 23%), "Behavioral" (23%, 19%), and "Low" (23%; 24%). Regardless of change in cognitive status, most residents remained in the same pain latent class. Among residents with stable, severe or worsening cognitive impairment, 11% in the "Behavioral" class transitioned to the "Behavioral and Severe Depression" class by 3 months. Fewer residents transitioned between latent classes in the 3- to 6-month period (>80% remained in their 3-month class). CONCLUSION: For nursing home residents unable to self-report pain, consideration of additional indicators including functioning, depressive symptoms, and agitation may be useful in identifying pain subgroups. Longitudinal changes in the pain subgroups over 6 months post-admission highlight that residents with severe cognitive impairment may be at risk for worsening pain.

Pain Behaviors and Pharmacological Pain Management Among Newly Admitted Nursing Home Residents.

BACKGROUND: Clinicians may place more weight on vocal complaints of pain than the other pain behaviors when making decisions about pain management. OBJECTIVES: We examined the association between documented pain behaviors and pharmacological pain management among nursing home residents. METHODS: We included 447,684 residents unable to self-report pain, with staff-documented pain behaviors (vocal, nonverbal, facial expressions, protective behaviors) and pharmacological pain management documented on the 2010-2016 Minimum Data Set 3.0. The outcome was no pharmacological pain medications, as needed only (pro re nata [PRN]), as scheduled only, or as scheduled with PRN medications. We estimated adjusted odds ratios and 95% confidence intervals from multinomial logistic models. RESULTS: Relative to residents with vocal complaints only, those with one pain behavior documented (i.e., nonverbal, facial, or protective behavior) were more likely to lack pain medication versus scheduled and PRN medications. Residents with multiple pain behaviors documented were least likely to have no treatment relative to scheduled with PRN medications, PRN only, or scheduled only pain medication regimens. DISCUSSION: The type and number of pain behaviors observed are associated with pharmacological pain management regimen. Improving staff recognition of pain among residents unable to self-report is warranted in nursing homes.

Development and psychometric evaluation of the Social Connectedness Index in nursing home residents with Alzheimer's disease and dementia using the Minimum Data Set 3.0.

OBJECTIVES: To develop a reliable and valid measure of social connectedness among nursing home residents with Alzheimer's disease and related dementias (ADRD) using items available in the Minimum Dataset 3.0 (MDS). METHODS: We conducted a retrospective scale development study using the 2016 MDS with two populations of nursing home residents with ADRD: (1) new admissions (not post-acute care) (n = 146,694); (2) residents with comprehensive annual assessments (n = 294,704). Twenty-nine items were included for consideration. Psychometric evaluation included content validity, item analysis, internal consistency reliability, criterion-related validity, and exploratory factor analysis. Analyses were stratified by self- or staff-assessed pain. RESULTS: The resulting five item Social Connectedness Index (SCI) has good content (Fleiss Kappa = 0.67), criterion-related and construct validity and adequate internal consistency reliability (Kuder Richardson-20: 0.63-0.74) in persons with ADRD. As anticipated, younger residents, men, and those with severe cognitive impairment, anxiety, and depression were more likely to be categorized in the low social connectedness group. CONCLUSION: The SCI is a promising measure for estimating the amount of social connectedness present for nursing home residents with ADRD. Further work needs to be done to evaluate the usefulness of the SCI for evaluating health and well-being among this population over time.
