Association of Occupational and Physical Therapy With Duration of Prescription Opioid Use After Hip or Knee Arthroplasty: A Retrospective Cohort Study of Medicare Enrollees

Implementability of opioid deprescribing interventions at transitions of care: A scoping review

Continuation of opioids at transitions of care increases the risk of long-term opioid use and related harm. To our knowledge, no study has examined the implementability of opioid deprescribing interventions at transitions of care. Our scoping review aimed to identify the type of opioid deprescribing interventions employed at transitions of care and assess the implementability of tested interventions. Nine electronic databases were searched on 15 May 2023 for English-language studies of adults transitioning between care settings, where opioid deprescribing interventions targeting patients, clinicians or health systems were implemented. Implementability was assessed using the Cochrane Intervention Complexity Assessment Tool for Systematic Reviews to determine intervention complexity, and mapped to the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework to understand the process evaluation. A total of 79 studies were identified, with 94.0% (n = 74) examining hospital-to-home transitions. Mixed interventions (combination of pharmacological and nonpharmacological) were tested in 49.0% (n = 39) of studies. Pharmacological interventions were identified in 31.0% (n = 24) of studies, and the remaining 20.0% (n = 16) applied nonpharmacological interventions. Mixed interventions comprising multiple components were the most complex and resulted in reduced opioid use across transitions of care in 28.0% (n = 22) of studies. Few studies reported on RE-AIM dimensions including implementation (5.0% of studies), reach (4.0%), adoption (4.0%) and maintenance (0%). Most opioid deprescribing interventions targeted hospital to home care transition with mixed results in opioid deprescribing. Further research should consider the implementability of interventions during transitions of care to elucidate the impact of opioid deprescribing interventions across care settings.

Rates and predictors of opioid deprescribing after fracture: A retrospective study of Medicare fee-for-service claims

BACKGROUND

Adults with Alzheimer's disease and Alzheimer's disease related dementias (ADRD) or frailty are susceptible to fractures. Opioid analgesics are frequently prescribed after fractures. Documenting post-fracture opioid discontinuation rates and predictors of discontinuation among adults with ADRD or frailty can inform clinical practice, identify potential disparities, and improve pain management guidelines. The objective of this paper was to investigate opioid discontinuation in opioid-naïve older adults who used opioids after an acute fracture.

METHODS

This retrospective cohort study included opioid-naïve Medicare fee-for-service beneficiaries (N = 33,027) ≥65 years of age who filled an opioid prescription within 30 days of a vertebral, lower extremity, or upper extremity fracture from 2013 to 2018. Beneficiaries were classified according to ADRD (yes/no) and frailty (yes/no) status using validated claims-based algorithms. The primary outcome was opioid discontinuation, defined as a 30-day supply gap. We estimated discontinuation rates with the Kaplan-Meier method and identified predictors of opioid discontinuation using Cox proportional hazards regression.

RESULTS

The 30-day opioid discontinuation rate was similar among non-frail beneficiaries without ADRD (81% [95% CI, 80%-81%]) and those who were non-frail with ADRD (83% [81%-84%]). Comparatively, 30-day discontinuation rates were lower among those with frailty and ADRD (76% [75%-77%]) and those with frailty alone (77% [75%-78%]). After adjusting for sociodemographic characteristics, health status, healthcare utilization, and calendar year, beneficiaries with both ADRD and frailty (HR, 0.90 [0.87-0.93]) and those with frailty alone (HR, 0.85 [0.82-0.89]), but not those with ADRD alone (HR, 1.06 [1.01-1.10]), were less likely to discontinue opioids compared with those without ADRD or frailty.

CONCLUSIONS AND RELEVANCE

Our findings suggest that frailty, but not ADRD, was associated with a lower likelihood of opioid discontinuation among older adults who initiated opioids after an acute fracture. Further research is needed to understand how opioid deprescribing practices depend on patient and provider preferences.

Racial Disparities in Outpatient Physical Therapy Use After Hip Fracture: A Retrospective Cohort Study

OBJECTIVE: To examine whether there was a racial disparity among Medicare beneficiaries in the likelihood of using outpatient physical therapy (PT) services following a hip fracture. METHODS: Our retrospective descriptive cohort study analyzed administrative claims data for 51 781 Medicare beneficiaries post hip fracture. We examined the association between race and PT use within the first 6 months post fracture using hierarchical logistic regression, adjusting for demographics, medical complexity, and socioeconomic factors. We used Poisson regression to examine the association between race and the number of PT visits. RESULTS: Only 31% of beneficiaries used outpatient PT after hip fracture with significant racial disparities. After controlling for demographics, medical complexity, and socioeconomic factors, Black beneficiaries had 42% lower odds of using PT (adjusted odds ratio [aOR], 0.58; 95% confidence interval [CI]: 0.51, 0.66) compared to White beneficiaries. Among PT users, Black beneficiaries received fewer visits than White beneficiaries (rate ratio [RR], 0.85; 95% CI: 0.82, 0.88) with this disparity persisting after adjustments (RR, 0.88; 95% CI: 0.85, 0.91). CONCLUSION: Even after adjusting for demographic, medical, and socioeconomic factors, Black beneficiaries were less likely to use outpatient PT following hip fractures. Conditional on an initial PT evaluation, Black beneficiaries received fewer sessions. J Orthop Sports Phys Ther 2024;54(12):1-7. Epub 9 October 2024. 10.2519/jospt.2024.12641.

Optimal Duration of Physical Therapy Following Total Knee Arthroplasty

Aims & Objectives

The purpose of this study was to identify patient characteristics associated with engagement and completion of physical therapy (PT) following total knee arthroplasty (TKA) and examine the relationship between number of PT sessions attended and outcomes during the first 12 weeks after surgery.

Methods

Patients underwent unilateral primary TKA by a single surgeon and were advised to complete 17 PT sessions over 6 weeks at a hospital-affiliated facility. Analyses examined predictors of PT engagement (attendance of ≥2 sessions) and completion (attendance of 17 ± 1 sessions) within 6 weeks and associations between number of PT sessions attended and changes in range of motion (ROM) and Knee Injury and Osteoarthritis Outcome Score (KOOS) values.

Results

Patients living <40 km were more likely to be engaged in PT than those living ≥40 km from the clinic (P < .0001). Among patients who completed PT within 6 weeks, 95.0%, 85.1%, and 56.4% achieved flexion of, respectively, ≥90°, ≥100°, and ≥110°. Among engaged patients, the active flexion thresholds of ≥90°, ≥100°, and ≥110° were achieved by, respectively, 94.4%, 82.5%, and 58.1% by 6 weeks and by 96.7%, 92.1%, and 84.2% by 12 weeks. Improvement in KOOS Symptoms (P = .029), Function in daily living (P = .030) and quality of life (P = .031) linearly decreased as number of PT sessions increased.

Conclusions

These results raise the question of whether patients who meet satisfactory outcomes before completing 6 weeks of prescribed PT and those who attend more PT sessions than prescribed may be over-utilizing healthcare resources without additional benefit.

Pain Control Associated With Gabapentinoid Prescription After Elective Total Knee Arthroplasty

BACKGROUND

Gabapentinoid (GABA) prescribing has substantially increased as a nonopioid analgesics for surgical conditions. We examined the effectiveness of GABA use for postoperative pain control among patients receiving total knee arthroplasty (TKA).

METHODS

This retrospective cohort study using 2016 to 2019 data from a 20% national sample of Medicare enrollees included patients aged 66 and over years who received an elective TKA, were discharged to home, received home health care, and had both admission and discharge assessments of pain (n = 35,186). Study outcomes were pain score difference between admission and discharge and less-than-daily pain interfering with activity at discharge. Opioid and GABA prescriptions after surgery and receipt of nerve block within 3 days of surgery were also assessed.

RESULTS

There were 30% of patients who had a pain score decrease of 3 to 4 levels and 55.8% had pain score decreases of 1 to 2 levels. In multivariable analyses, receiving a nerve block was significantly associated with pain score reduction. A GABA prescription increased the magnitude of pain score reduction among those receiving a nerve block. Results from inverse probability weighted analysis with propensity score showed that coprescribing of GABA and low-dose opioid was associated with significantly lower pain scores.

CONCLUSIONS

Post-TKA opioid use was not associated with pain score reduction. Receiving a nerve block was associated with a modest pain score reduction. Co-prescribing GABA with low-dose opioid or receiving a nerve block was associated with increasing magnitudes of pain reduction. Further research should identify alternatives to opioid use for managing postoperative TKA pain.

Pain and incident cognitive impairment in very old Mexican American adults

BACKGROUND

Studies have investigated the association between pain and cognitive impairment among older adults, but the findings are mixed. We assessed the relationship of activity-limiting pain (pain interference) with incident cognitive impairment and the mediating effect of depressive symptoms among Mexican American adults aged ≥80.

METHODS

Data were taken from the Hispanic Established Population for the Epidemiological Study of the Elderly (2010-2016). Pain interference, or pain that limited daily activities in the last 12 months, was categorized into none, untreated pain interference, and treated pain interference. Cognitive impairment was defined as scoring <21 on the Mini-Mental State Examination and difficulty with at least one instrumental activity of daily living. We used general estimation equations to assess this relationship between pain and incident cognitive impairment over the 6-year period (n = 313).

RESULTS

Participants reporting both untreated and treated pain interference had higher odds of incident cognitive impairment than those reporting no pain or pain interference (untreated adjusted odds ratio [aOR]: 2.18; 95% confidence interval [CI]: 1.09-4.36; treated aOR: 1.99; 95% CI: 1.15-3.44). Depressive symptoms explained 15.0% of the total effect of untreated pain and 25.3% of treated pain.

CONCLUSIONS

Among very old Mexican American adults, both treated and untreated pain interference was associated with incident cognitive impairment. This association was partially mediated by depressive symptoms, underscoring a need for depression screening in patients with chronic pain. Future work is needed to examine mechanistic/causal pathways between pain and subsequent cognitive impairment and the role of pharmacological and non-pharmacological treatments in these pathways.

Inequitable access to nonpharmacologic pain treatment providers among cancer-free U.S. adults

OBJECTIVE

Using evidence-based nonpharmacologic pain treatments may prevent opioid overuse and associated adverse outcomes. There is limited data on the impact of access-promoting social determinants of health (SDoH: education, income, transportation) on use of nonpharmacologic pain treatments. Our objective was to examine the relationship between SDoH and use of nonpharmacologic pain treatment providers. Our goal was to understand policy-actionable factors contributing to inequity in pain treatment.

METHODS

Based on Andersen's Health Utilization Model, this cross-sectional analysis of 2016-2019 Medical Expenditure Panel Survey data evaluated whether use of outpatient nonpharmacologic pain treatment providers is driven by enabling (i.e., advantageous socioeconomic resources) or need (i.e., perceived disability and diagnosed disease) factors. The study sample (unweighted n = 28,188) represented a weighted N = 81,912,730 noninstitutionalized, cancer-free, U.S. adults with pain interference. The primary outcome measured use of nonpharmacologic providers relative to exclusive prescription opioid use or no treatment (i.e., neither opioids nor nonpharmacologic). To quantify equitable access, we compared the variance-between access-promoting enabling factors versus medical need factors-that explained utilization.

RESULTS

Compared to enabling factors, need factors explained twice the variance predicting pain treatment utilization. Still, the adjusted odds of using nonpharmacologic providers instead of opioids alone were 39% lower among respondents identifying as Black (95% Confidence Interval [CI], 0.49-0.76) and respondents residing in the U.S. South (95% CI, 0.51-0.74). Higher education (95% CI, 1.72-2.79) and income (95% CI, 1.68-2.42) both facilitated using nonpharmacologic providers instead of opioids.

CONCLUSIONS

These findings highlight the substantial influence access-promoting SDoH have on pain treatment utilization.

Orthopedic surgeons and physical therapists differ regarding rehabilitative needs after lower extremity fracture repair

BACKGROUND

Little evidence is available to guide physical therapy (PT) following lower extremity fracture repair distal to the hip. As such, variability has been reported in the way PT is utilized post-operatively. Examination of current practice by orthopedic surgeons (OS) and physical therapists is needed to inform clinical practice guidelines in this area.

OBJECTIVE

To describe current PT referral practices among OS, identify patient and clinical factors that affect PT referral, and examine differences between OS and physical therapists with regard to visit frequency, duration, and use of specific PT interventions.

METHODS

Provider surveys.

RESULTS

Surveys were completed by 100 OS and 347 physical therapists. Over half (54%) of OS reported referring "most patients" to PT and identified joint stiffness and strength limitations as top reasons for PT referral. Over 80% of OS and physical therapists indicated that joint stiffness, strength limitations, and patients' functional goals affected their recommendations for PT visit frequency. More physical therapists than OS reported that pain severity (55% vs 25%, p < .001), maladaptive pain behaviors (64% vs. 33%, p < .001), and patient self-efficacy (70% vs. 49%, p = .003) affected their visit frequency recommendations. While OS recommended more frequent PT for patients with peri-articular fractures, fracture type had minimal impact on the visit frequencies recommended by physical therapists.

CONCLUSION

OS and physical therapists consider similar physical impairments when determining the need for PT and visit frequencies, however, physical therapists consider pain and psychosocial factors more often, with OS focusing more on injury type.

Increase in the Initial Outpatient Rehabilitation Utilization for Patients With Total Knee Arthroplasty

OBJECTIVES

The objective of this study was to examine the patient characteristics and features associated with the initial rehabilitation utilization with a particular emphasis on outpatient rehabilitation after total knee arthroplasty (TKA) among 2016-2018 Texas Medicare enrollees.

DESIGN

This is a retrospective cohort study. We used chi-square tests to examine the variability in patient demographic and clinical characteristics across the different post-acute rehabilitation settings after TKA. A Cochran-Armitage trend test was used to investigate the yearly trend of outpatient rehabilitation utilization after TKA.

SETTING

Post-acute rehabilitation settings after TKA.

PARTICIPANTS

The target population was Medicare beneficiaries aged ≥65 with an initial TKA in 2016-2018 and complete demographic and residential information (N=44,313).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

We identified whether patients first used (1) outpatient rehabilitation, (2) home health, (3) self-care, (4) inpatient rehabilitation, (5) skilled nursing, or (6) other setting within the 3 months after TKA.

RESULTS

Our results demonstrated an increasing use of the initial outpatient rehabilitation and home health, while the use of skilled nursing and inpatient rehabilitation facilities decreased from 2016 to 2018. The increase in outpatient utilization was significant in 2018 compared with 2016 controlling for distance to the TKA facilities, comorbid conditions, sex, race/ethnicity groups (White, Black, Hispanic, and Others), lower income (Medicaid eligible), Medicare entitlement types, age groups, and rurality (OR 1.23, 95% CI 1.12-1.34). However, the overall utilization rate of the initial outpatient rehabilitation after TKA remained low, increasing from 7.36% in 2016 to 8.60% in 2018.

CONCLUSION

Despite the growing use of the initial outpatient rehabilitation after TKA, the overall rate of outpatient rehabilitation utilization remained low. Our findings raise an important question as to whether certain patient demographics and clinical groups might have limited access to outpatient rehabilitation after TKA.

Characteristics of Early Interventions for Pain and Function Following Lower Extremity Joint Replacement: Systematic Review

Occupational therapy is beneficial among adults with chronic pain; however, occupational therapy interventions addressing earlier phases of pain have not been clearly explicated. This systematic review characterized acute and subacute interventions billable by occupational therapy after hip or knee replacement to improve pain and function. Seven articles met inclusion criteria. Six articles had a low risk of bias. Three intervention types were found: task-oriented exercise, water-based, and modalities. Only task-oriented interventions improved both pain and function one-year after surgery. There are long-term benefits to early task-oriented exercise. Further research is needed to contextualize occupational therapy's role in early pain interventions.

Team Approach: Use of Opioids in Orthopaedic Practice

»

The opioid epidemic represents a serious health burden on patients across the United States.

»

This epidemic is particularly pertinent to the field of orthopaedics because it is one of the fields providing the highest volume of opioid prescriptions.

»

The use of opioids before orthopaedic surgery has been associated with decreased patient-reported outcomes, increased surgery-related complications, and chronic opioid use.

»

Several patient-level factors, such as preoperative opioid consumption and musculoskeletal and mental health conditions, contribute to the prolonged use of opioids after surgery, and various screening tools for identifying high-risk drug use patterns are available.

»

The identification of these high-risk patients should be followed by strategies aimed at mitigating opioid misuse, including patient education, opioid use optimization, and a collaborative approach between health care providers.

Trends in the Use of Opioids vs Nonpharmacologic Treatments in Adults With Pain, 2011-2019

IMPORTANCE

Chronic pain prevalence among US adults increased between 2010 and 2019. Yet little is known about trends in the use of prescription opioids and nonpharmacologic alternatives in treating pain.

OBJECTIVES

To compare annual trends in the use of prescription opioids, nonpharmacologic alternatives, both treatments, and neither treatment; compare estimates for the annual use of acupuncture, chiropractic care, massage therapy, occupational therapy, and physical therapy; and estimate the association between calendar year and pain treatment based on the severity of pain interference.

DESIGN, SETTING, AND PARTICIPANTS

A serial cross-sectional analysis was conducted using the nationally representative Medical Expenditure Panel Survey to estimate the use of outpatient services by cancer-free adults with chronic or surgical pain between calendar years 2011 and 2019. Data analysis was performed from December 29, 2021, to August 5, 2022.

EXPOSURES

Calendar year (2011-2019) was the primary exposure.

MAIN OUTCOMES AND MEASURES

The association between calendar year and mutually exclusive pain treatments (opioid vs nonpharmacologic vs both vs neither treatment) was examined. A secondary outcome was the prevalence of nonpharmacologic treatments (acupuncture, chiropractic care, massage therapy, occupational therapy, and physical therapy). All analyses were stratified by pain type.

RESULTS

Among the unweighted 46 420 respondents, 9643 (20.4% weighted) received surgery and 36 777 (79.6% weighted) did not. Weighted percentages indicated that 41.7% of the respondents were aged 45 to 64 years and 55.0% were women. There were significant trends in the use of pain treatments after adjusting for demographic factors, socioeconomic status, health conditions, and pain severity. For example, exclusive use of nonpharmacologic treatments increased in 2019 for both cohorts (chronic pain: adjusted odds ratio [aOR], 2.72; 95% CI, 2.30-3.21; surgical pain: aOR, 1.53; 95% CI, 1.13-2.08) compared with 2011. The use of neither treatment decreased in 2019 for both cohorts (chronic pain: aOR, 0.43; 95% CI, 0.37-0.49; surgical pain: aOR, 0.59; 95% CI, 0.46-0.75) compared with 2011. Among nonpharmacologic treatments, chiropractors and physical therapists were the most common licensed healthcare professionals.

CONCLUSIONS AND RELEVANCE

Among cancer-free adults with pain, the annual prevalence of nonpharmacologic pain treatments increased and the prevalent use of neither opioids nor nonpharmacologic therapy decreased for both chronic and surgical pain cohorts. These findings suggest that, although access to outpatient nonpharmacologic treatments is increasing, more severe pain interference may inhibit this access.

Opioid and Benzodiazepine Substitutes: Impact on Drug Overdose Mortality in Medicare Population

INTRODUCTION

Gabapentinoids (GABAs) and serotonergic drugs (selective serotonin reuptake inhibitors [SSRIs]/serotonin and norepinephrine reuptake inhibitors [SNRIs]) are increasingly being prescribed as potential substitutes to opioids and benzodiazepines (benzos), respectively, to treat co-occurring pain and anxiety disorders. The toxicities of these drug classes and their combinations are not well understood.

METHODS

We conducted a matched case-control study using 2013-2016 Medicare files linked to the National Death Index. Cases were enrollees who died from drug overdose. Controls were enrollees who died from other causes. Cases and controls were matched on patient characteristics and prior chronic conditions. Possession of any opioids, GABAs, benzos, and SSRIs/SNRIs in the month prior to death was defined as drug use. Combination drug use was defined as possessing at least 2 types of these prescriptions for an overlapping period of at least 7 days in the month prior to death.

RESULTS

Among 4323 matches, benzo possession was associated with twice the risk for drug overdose death in cases vs controls. Compared with opioid-benzo co-prescribing, combinations involving SSRIs/SNRIs and opioids (or GABAs) were associated with decreased risk (adjusted odds ratio 0.55; 95% confidence interval, 0.44-0.69 for opioids and SSRIs/SNRIs; adjusted odds ratio 0.59; 95% confidence interval, 0.44-0.79 for GABAs and SSRIs/SNRIs). Fatal drug overdose risk was similar in users of GABA-opioid, GABA-benzo, and opioid-benzo combinations.

CONCLUSIONS

Benzodiazepines, prescribed alone or in combination, were associated with an increased risk of drug overdose death. SSRIs/SNRIs were associated with lower risk of overdose death vs benzodiazepines. GABAs were not associated with decreased risk compared with opioids, raising concerns for GABAs' perceived relative safety.

Incident Functional Limitations Among Community-Dwelling Adults Using Opioids: A Retrospective Cohort Study Using a Propensity Analysis with the Health and Retirement Study

BACKGROUND

Opioid analgesics are commonly used to manage pain; however, it is unclear how they affect patient function. This study examines the association between opioid analgesics and incident limitations in activities of daily living (ADL), instrumental activities of daily living (IADL), and cognitive functioning among community-dwelling older adults.

METHODS

Data included 10,003 participants of the 2016 and 2018 waves of the Health and Retirement Study, which sampled US adults aged 51-98 years. The primary exposure was self-reported opioid pain medication use in 2016. Outcomes included incident limitations in ADL, IADL, and cognitive functioning in 2018. Statistical methods adjusted for confounding using multivariable logistic regressions, inverse probability of treatment weighting, and propensity scores.

RESULTS

Opioid use (adjusted odds ratio [aOR]: 1.34, 95% confidence interval [CI] 1.07-1.68) was associated with a statistically significant higher odds of incident ADL limitation in multivariable regression and in propensity score adjustment (aOR: 1.41, 95% CI 1.13-1.76). The association between opioid use and ADL and IADL limitations was modified by age. Adults aged < 65 years had a higher odds of incident ADL (aOR: 1.83, 95% CI 1.38-2.42) and IADL (aOR: 1.42, 95% CI 1.06-1.90) limitations compared with those aged ≥ 65 years.

CONCLUSIONS

Community-dwelling adults using opioid analgesics to manage pain may be at risk for incident ADL limitations. Middle-aged adults, compared with those older than 65 years of age, experienced the greatest odds for incident ADL and IADL limitations following opioid use. According to sensitivity analyses, our findings were robust to unmeasured confounding.
