Nonopioid analgesic use in older patients admitted for orthopedic rehabilitation.

BACKGROUND: Multimodal analgesia (MMA) combines opioids with nonopioid analgesics (NOAs) to mitigate opioid-related adverse events and development of opioid use disorders. Although MMA has become the standard for orthopedic perioperative pain management, guidance is less clear for the approximately 15% of patients who go on to require inpatient orthopedic rehabilitation (IOR) postoperatively. The IOR population tends to be older and frailer and hence likely more vulnerable to adverse events. Little research has been done to shed light on how NOAs are used in this population. OBJECTIVE: To characterize NOA prescribing in older versus younger adults during IOR admissions and to determine predictors of NOA prescribing in an older IOR population. DESIGN: Retrospective case-control study. SETTING: Two IOR wards at an academic rehabilitation hospital in Toronto, Canada. PATIENTS: All patients aged ≥50 years admitted for an orthopedic indication between November 2019 and June 2021; the patients aged <65 group was included for comparative characterization of NOA prescribing versus older peers. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Medication use and adverse events, pain, and rehabilitation outcomes such as the Functional Independence Measure, discharge destination, and length of stay. RESULTS: A total of 643 patient encounters were included; 48.2% used NOA. Age (odds ratio [OR]: 0.97; confidence interval [CI]: 0.95-0.99, p < .001) and prior NOA use (OR: 3.15; CI: 2.0-4.9, p < .001) were associated with NOA prescribing. Other positively associated factors included body mass index, psychiatric history, elective surgery, and admission from a specific referring hospital. Adverse events between NOA users and nonusers were similar. CONCLUSIONS: NOA prescribing is heterogeneous and declines with age in IOR. This points to an opportunity to explore integrating NOA into opioid-sparing MMA protocols tailored to older IOR patients, along with further study of the safety and benefit of these regimens.

Opioid use in older orthopedic rehabilitation inpatients: a retrospective study.

BACKGROUND: While there is much evidence about pain management for orthopedic patients in the immediate perioperative setting, little is known about how opioids are used during inpatient rehabilitation, particularly in older adults. A safe upper limit of 50 mg oral morphine equivalents (OME) is frequently cited in guidelines. AIM: The aim of this study was to characterize the dosing of opioids in an older adult population undergoing inpatient orthopedic rehabilitation (IOR). DESIGN: Retrospective observational study. SETTING: Inpatient units at an academic rehabilitation hospital in Toronto, Canada. POPULATION: All adults aged ≥50 years old admitted for orthopedic rehabilitation between November 2019 and June 2021 following acute care admissions for either a surgical or non-surgical orthopedic indication. METHODS: Participants were divided into groups of prior opioids users, new opioids users, and opioid non-users during IOR. Demographic, clinical, and medication administration data were collected through the electronic health record and manual chart review. Average daily opioid dose for the first seven days of each stay was characterized using OME. Linear regression was used to assess for variables independently associated with opioid dose. RESULTS: A total of 643 patients undergoing orthopedic rehabilitation were included: 125 (19.4%) were prior opioid users, 416 (64.7%) were new opioid users, and 102 (15.9%) were non-users, with median age respectively of 72, 79, and 83. Median daily OME over the first week for prior users was 30.3 and for new users was 6.9. Opioid dose was inversely associated with age and admission for a non-surgical indication; it was positively associated with reported pain (as defined by day 3 pain score) and admission for knee replacement. CONCLUSIONS: Opioids are frequently but heterogeneously used in older adults undergoing IOR. Median OME use in this cohort of older adults was substantially lower than the 50 OME threshold suggested in guidelines, particularly for new opioid users. CLINICAL REHABILITATION IMPACT: Older adults require much lower opioid doses than younger patients. Pain management in older orthopedic rehabilitation inpatients is distinct from the perioperative setting and deserves tailored guidance, with a focus on using the lowest effective dose.

Recurrence of biliary disease following non-operative management in elderly patients.

INTRODUCTION: The purpose of this study was to determine the proportion of symptomatic recurrence following initial non-operative management of gallstone disease in the elderly and to test possible predictors. METHODS: This is a single institution retrospective chart review of patients 65 years and older with an initial hospital visit (V1) for symptomatic gallstone disease, over a 4-year period. Patients with initial "non-operative" management were defined as those without surgery at V1 and without elective surgery at visit 2 (V2). Baseline characteristics included age, sex, Charlson comorbidity index (CCI), diagnosis, and interventions (ERCP or cholecystostomy) at V1. Outcomes assessed over 1 year were as follows: recurrence (any ER/admission visit following V1), surgery, complications, and mortality. A survival analysis using a Cox proportional hazards model was performed to assess predictors of recurrence. RESULTS: There were 195 patients initially treated non-operatively at V1. Mean age was 78.3 ± 7.8 years, 45.6% were male, and the mean CCI was 2.1 ± 1.9. At V1, 54.4% had a diagnosis of biliary colic or cholecystitis, while 45.6% had a diagnosis of cholangitis, pancreatitis, or choledocholithiasis. 39.5% underwent ERCP or cholecystostomy. Excluding 10 patients who died at V1, 31.3% of patients had a recurrence over the study period. Among these, 43.5% had emergency surgery, 34.8% had complications, and 4.3% died. Median time to first recurrence was 2 months (range 6 days-4.8 months). Intervention at V1 was associated with a lower probability of recurrence (HR 0.3, CI [0.14-0.65]). CONCLUSION: One-third of elderly patients will develop a recurrence following non-operative management of symptomatic biliary disease. These recurrences are associated with significant rates of emergency surgery and morbidity. Percutaneous or endoscopic therapies may decrease the risk of recurrence.

Gallstone disease in the elderly: are older patients managed differently?

BACKGROUND: This study aimed to describe the differences in the management of symptomatic gallstone disease within different elderly groups and to evaluate the association between older age and surgical treatment. METHODS: This single-institution retrospective chart review included all patients 65 years old and older with an initial hospital visit for symptomatic gallstone disease between 2004 and 2008. The patients were stratified into three age groups: group 1 (age, 65-74 years), group 2 (age, 75-84 years), and group 3 (age, ≥ 85 years). Patient characteristics and presentation at the initial hospital visit were described as well as the surgical and other nonoperative interventions occurring over a 1-year follow-up period. Logistic regression was performed to assess the effect of age on surgery. RESULTS: Data from 397 patient charts were assessed: 182 in group 1, 160 in group 2, and 55 in group 3. Cholecystitis was the most common diagnosis in groups 1 and 2, whereas cholangitis was the most common diagnosis in group 3. Elective admissions to a surgical ward were most common in group 1, whereas urgent admissions to a medical ward were most common in group 3. Elective surgery was performed at the first visit for 50.6% of group 1, for 25.6% of group 2, and for 12.7% of group 3, with a 1-year cumulative incidence of surgery of 87.4% in group 1, 63.5% in group 2, and 22.1% in group 3. Inversely, cholecystostomy and endoscopic retrograde cholangiopancreatography (ERCP) were used more often in the older groups. Increased age (odds ratio [OR], 0.87; 95% confidence interval [CI], 0.84-0.91) and the Charlson Comorbidity Index (OR, 0.80; 95% CI, 0.69-0.94) were significantly associated with a decreased probability of undergoing surgery within 1 year after the initial visit. CONCLUSION: Even in the elderly population, older patients presented more frequently with severe disease and underwent more conservative treatment strategies. Older age was independently associated with a lower likelihood of surgery.
