Pain Management Issues for the Geriatric Surgical Patient

Evolving Concepts of Pain Management in Elderly Patients

PURPOSE OF REVIEW

The elderly population typically suffer from a variety of diseases that mostly reflect the degenerative changes linked with the aging process. These diseases may be exacerbated by acute pain or by an abrupt aggravation of previously stable chronic pain.

RECENT FINDINGS

Physical and psychological changes associated with aging may influence one's experience of pain and, as a result, the severity of pain. Pain treatment in the elderly can be complex and is often a budgetary burden on the nation's health care system. These difficulties arise, in part, because of unanticipated pharmacodynamics, changed pharmacokinetics, and polypharmacy interactions. Therefore, it is critical to integrate a multidisciplinary team to develop a management strategy that incorporates medical, psychological, and surgical methods to control persistent pain conditions. It is in this critical process that pain prediction models can be of great use. The purpose of pain prediction models for the elderly is the use of mathematical models to predict the occurrence and intensity of pain and pain-related conditions. These mathematical models employ a vast quantity of data to ascertain the many risk factors for the development of pain problems in the elderly, whether said risks are adjustable or not. These models will pave the way for more informed medical decision making that are based on the findings of thousands of patients who have previously experienced the same illness and related pain conditions. However, future additional research needs to be undertaken to build prediction models that are not constrained by substantial legal or methodological limitations.

Effect of subanesthetic dose of esketamine on postoperative pain in elderly patients undergoing laparoscopic gastrointestinal tumor Surgery:A prospective, double-blind, randomized controlled trial

Purpose

Postoperative pain is prevalent and severe complication in elderly surgical patients. Multiple studies propose that a small dose of esketamine administered intraoperatively can alleviate postoperative pain and curtail opioid usage. We aimed to evaluate the impact of esketamine on postoperative acute pain among elderly patients with gastrointestinal tumors.

Patients and methods

This is a prospective, parallel-group, randomized controlled trial. Ninety patients aged 60 and above, undergoing resection of gastrointestinal tumors, were randomly assigned to two groups: esketamine group (Group S, a single dose of 0.25 mg/kg and 0.1 mg/kg/h infusion) and control group (Group C, saline). Visual Analogue Scale (VAS) pain scores were the primary outcome. Remifentanil consumption, instances of rescue analgesia, delirium, sleep quality, postoperative recovery quality, serum levels of inflammatory cytokines, and adverse events within 72 h post-surgery were secondary outcomes, respectively.

Results

Data of 87 of 99 eligible patients were analyzed. VAS scores at rest in Group S were lower than those in Group C at 6 h [1.2 (0.6, 1.6) vs 1.6 (1.0, 2.0), P = 0.003], 12 h [1.4 (1.0, 2.0) vs 2.0 (1.5, 2.0), P < 0.001], and 24 h [1.8 (1.3, 2.0) vs 2.2 (1.6, 2.6), P < 0.001] postoperatively. At 6 h post-surgery, VAS score during coughing was lower in Group S than Group C [2.0 (2.0, 2.3) vs 2.0 (2.0, 3.0), P = 0.009]. The instances of rescue analgesia were fewer in group S compared to group C (P = 0.007). Furthermore, the esketamine group showed improved sleep quality and QoR-15 score (P < 0.05) postoperatively.

Conclusion

Intravenous administration of esketamine as an adjunct to general anesthesia can decrease the intensity of pain for 24 h without additional adverse effects after laparoscopic gastrointestinal tumor surgery.

Could epidural analgesia be safely used for acute postoperative pain in older adults to enhance recovery?

Epidural analgesia is often considered cornerstone in multimodal analgesia when used in major surgeries. However, its role in managing acute postoperative pain in elderly patients is debatable because of its known potential complications. Furthermore, postoperative pain in elderly patients is under-treated because of complex comorbidities, and they are more prone to adverse events related to pain therapies. All systemic analgesic drugs have pharmacological limitations and precautions in elderly people. Recent meta-analyses showed that epidural analgesia provided better postoperative pain control compared to intravenous opioids. Interestingly, peripheral nerve blocks had no superior control of pain over epidural analgesia. In addition, epidural analgesia has shown to positively affect perioperative morbidities and mortalities, and reduce opioid-related side effects because of its non-analgesic effects on each organ system. When tailored in a specific multimodal approach, it shortens the intensive care and hospital stays. In conclusion, if complications are identified and treated early, and contraindications are ruled out, epidural analgesia can achieve sufficient postoperative pain management with insignificant adverse events in this population.

Optimization of Care for the Elderly Surgical Emergency Patient

Geriatric patients undergoing emergency surgery are at significantly higher risk for complications and death when compared with younger patients. Optimizing care for these patients requires a multidisciplinary team, special attention to physiologic changes and medication use, as well as targeted intervention to mitigate complications such as delirium, which can worsen overall outcomes. Frailty can be assessed preoperatively to identify patients at the highest risk for complications. Shared decision-making with both the family and patient during the consent process is integral to defining patient's goals of care in these high-risk situations.

Anesthesia and perioperative pain relief in the frail elderly patient

Demand for anesthesia and analgesia for the frail elderly is continuously increasing as the likelihood of encountering very elderly, very vulnerable, and very compromised patients has, ever so subtly, increased over the last three decades. The anesthesiologist has, increasingly, been obliged to offer professional services to frail patients. Fortunately, there has been a dramatic improvement in medications, methods of drug delivery, critical monitoring, and anesthesia techniques. Specific methodologies peculiar to the frail are now taught and practiced across all anesthesia subspecialties. However, administering anesthesia for the frail elderly is vastly different to giving an anesthetic to the older patient. Frail patients are increasingly cared for in specialized units-geriatric intensive therapy units, post-acute care services, palliative, hospices, and supportive care and aged care facilities. Several medications (e.g., morphine-sparing analgesics) more suited to the frail have become universally available in most centers worldwide so that best-practice, evidence-based anesthesia combinations of drugs and techniques are now increasingly employed. Every anesthetic and pain management techniques in the frail elderly patient are going to be discussed in this review.

Pain Management in the Elderly: A Narrative Review

With the increase in life expectancy in the United States, octogenarians and nonagenarians are more frequently seen in clinical practice. The elderly patients have multiple preexisting comorbidities and are on multiple medications, which can make pain management complex. Moreover, the elderly population often suffers from chronic pain related to degenerative processes, making medical management challenging. In this review, the authors collated available evidence for best practices for pain management in the elderly.

Trends in the Use of Gabapentinoids and Opioids in the Postoperative Period Among Older Adults

Importance

In response to the opioid epidemic, recommendations from some pain societies have encouraged surgeons to embrace multimodal pain regimens with the intent of reducing opioid use in the postoperative period, including by prescribing gabapentinoids.

Objective

To describe trends in postoperative prescribing of both gabapentinoids and opioids after a variety of surgical procedures by examining nationally representative Medicare data and further understand variation by procedure.

Design, Setting, and Participants

This serial cross-sectional study of gabapentinoid prescribing from January 1, 2013, through December 31, 2018, used a 20% US Medicare sample. Gabapentinoid-naive patients 66 years or older undergoing 1 of 14 common noncataract surgical procedures performed in older adults were included. Data were analyzed from April 2022 to April 2023.

Exposure

One of 14 common surgical procedures in older adults.

Main Outcomes and Measures

Rate of postoperative prescribing of gabapentinoids and opioids, defined as a prescription filled between 7 days before the procedure and 7 days after discharge from surgery. Additionally, concomitant prescribing of gabapentinoids and opioids in the postoperative period was assessed.

Results

The total study cohort included 494 922 patients with a mean (SD) age of 73.7 (5.9) years, 53.9% of whom were women and 86.0% of whom were White. A total of 18 095 patients (3.7%) received a new gabapentinoid prescription in the postoperative period. Of those receiving a new gabapentinoid prescription, 10 956 (60.5%) were women and 15 529 (85.8%) were White. After adjusting for age, sex, race and ethnicity, and procedure type in each year, the rate of new postoperative gabapentinoid prescribing increased from 2.3% (95% CI, 2.2%-2.4%) in 2014 to 5.2% (95% CI, 5.0%-5.4%) in 2018 (P < .001). While there was variation between procedure types, almost all procedures saw an increase in both gabapentinoid and opioid prescribing. In this same period, opioid prescribing increased from 56% (95% CI, 55%-56%) to 59% (95% CI, 58%-60%) (P < .001). Concomitant prescribing also increased from 1.6% (95% CI, 1.5%-1.7%) in 2014 to 4.1% (95% CI, 4.0%-4.3%) in 2018 (P < .001).

Conclusions and Relevance

The findings of this cross-sectional study of Medicare beneficiaries suggest that new postoperative gabapentinoid prescribing increased without a subsequent downward trend in the proportion of patients receiving postoperative opioids and a near tripling of concurrent prescribing. Closer attention needs to be paid to postoperative prescribing for older adults, especially when using multiple types of medications, which can have adverse drug events.

Opioid-Free Forefoot Surgery vs Traditional Perioperative Opiate Regimen: A Randomized Controlled Trial

BACKGROUND

In response to the opioid epidemic, the use of multimodal pain management in orthopaedic surgery is increasing. Efforts to decrease opioid prescribing and opioid consumption among foot and ankle surgical patients are needed. The purpose of this study was to compare the efficacy and adverse events between 2 multimodal pain management pathways for forefoot surgical patients: standard opioid-containing (OC) and opioid-free (OF).

METHODS

This is a single-center noninferior randomized controlled trial of 51 patients undergoing forefoot surgery allocated to one of 2 perioperative pain management treatments: opioid-free, multimodal (OF, n=27 patients), or traditional opioid-containing (OC, n=24 patients). Patient characteristics, creatine markers, pain (numeric rating scale [NRS]), general health (Veterans Rand 12-Item Health Survey [VR-12]), and depression were measured preoperatively. Postoperatively, pain was measured at 24-hour, 2-week, and 6-week time points. Satisfaction with pain control, complications, and general health were measured at 2 and 6 weeks.

RESULTS

The OF group is statistically noninferior to the OC group and reported lower median pain scores at 24 hours (2 [IQR 0, 3] vs 6 [IQR 3.5, 7]; p<.0001) and 2 weeks (2 [IQR 1, 4] vs 4 [IQR 0, 3]; p=.018]. By 6 weeks, pain levels were similar between groups. More than 85% of all patients reported satisfaction with pain level at 2 weeks, which increased to >90% at 6 weeks. The VR-12 scores were similar between groups across all time points. At 2 weeks, 8 patients in each group reported constipation. By 6 weeks, all but 2 OC patients reported resolution. No other adverse events of postoperative wound complications, readmissions, medication reactions, thrombosis, or persistent pain were documented.

CONCLUSION

In forefoot surgery, the opioid-free pain management protocol was statistically noninferior to the opioid-containing protocol in reducing postoperative pain.

LEVEL OF EVIDENCE

Level II, prospective cohort study.

Prolonged use of newly prescribed gabapentin after surgery

BACKGROUND

Surgeons have made substantial efforts to decrease postoperative opioid prescribing, largely because it can lead to prolonged use. These efforts include adoption of non-opioid pain medication including gabapentin. Like opioids, gabapentin use may be prolonged, increasing the risk of altered mental status and even overdose and death when taken concurrently with opioids. However, little is known about postoperative prolonged use of gabapentin in older adults.

METHODS

We merged a 20% sample of Medicare Carrier, MedPAR and Outpatient Files with Part D for 2013-2018. We included patients >65 years old without prior gabapentinoid use who underwent common non-cataract surgical procedures. We defined new postoperative gabapentin as fills for 7 days before surgery until 7 days after discharge. We excluded patients whose discharge disposition was hospice or death. The primary outcome was prolonged use of gabapentin, defined as a fill>90 days after discharge. To identify risk factors for prolonged use, we constructed logistic regression models, adjusted for procedure and patient characteristics, length of stay, disposition location, and care complexity.

RESULTS

Overall, 17,970 patients (3% of all eligible patients) had a new prescription for gabapentin after surgery. Of these, the mean age was 73 years old and 62% were female. The most common procedures were total knee (45%) and total hip (21%) replacements. Prolonged use occurred in 22%. Those with prolonged use were more likely to be women (64% vs. 61%), be non-White (14% vs. 12%), have concurrent prolonged opioid use (44% vs. 18%), and have undergone emergency surgery (8% vs. 4%). On multivariable analysis, being female, having a higher Charlson comorbidity score, having an opioid prescription at discharge and at >90 days and having a higher care complexity were associated with prolonged use of gabapentin.

CONCLUSIONS

More than one-fifth of older adults prescribed gabapentin postoperatively filled a prescription >90 days after discharge, especially among patients with more comorbidities and concurrent prolonged opioid use, increasing the risk of adverse drug events and polypharmacy.

Postoperative outcomes in older surgical patients with preoperative cognitive impairment: A systematic review and meta-analysis

STUDY OBJECTIVE

To determine the effect of cognitive impairment (CI) and dementia on adverse outcomes in older surgical patients.

DESIGN

A systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs). Various databases were searched from their inception dates to March 8, 2021.

SETTING

Preoperative assessment.

PATIENTS

Older patients (≥ 60 years) undergoing non-cardiac surgery.

MEASUREMENTS

Outcomes included postoperative delirium, mortality, discharge to assisted care, 30-day readmissions, postoperative complications, and length of hospital stay. Effect sizes were calculated as Odds Ratio (OR) and Mean Difference (MD) based on random effect model analysis. The quality of included studies was assessed using the Cochrane Risk Bias Tool for RCTs and Newcastle-Ottawa Scale for observational cohort studies.

RESULTS

Fifty-three studies (196,491 patients) were included. Preoperative CI was associated with a significant risk of delirium in older patients after non-cardiac surgery (25.1% vs. 10.3%; OR: 3.84; 95%CI: 2.35, 6.26; I²: 76%; p < 0.00001). Cognitive impairment (26.2% vs. 13.2%; OR: 2.28; 95%CI: 1.39, 3.74; I²: 73%; p = 0.001) and dementia (41.6% vs. 25.5%; OR: 1.96; 95%CI: 1.34, 2.88; I²: 99%; p = 0.0006) significantly increased risk for 1-year mortality. In patients with CI, there was an increased risk of discharge to assisted care (44.7% vs. 38.3%; OR 1.74; 95%CI: 1.05, 2.89, p = 0.03), 30-day readmissions (14.3% vs. 10.8%; OR: 1.36; 95%CI: 1.00, 1.84, p = 0.05), and postoperative complications (40.7% vs. 18.8%; OR: 1.85; 95%CI: 1.37, 2.49; p < 0.0001).

CONCLUSIONS

Preoperative CI in older surgical patients significantly increases risk of delirium, 1-year mortality, discharge to assisted care, 30-day readmission, and postoperative complications. Dementia increases the risk of 1-year mortality. Cognitive screening in the preoperative assessment for older surgical patients may be helpful for risk stratification so that appropriate management can be implemented to mitigate adverse postoperative outcomes.

An Enhanced Recovery After Surgery Protocol Decreases the Use of Narcotics in Infrainguinal Bypass Patients

OBJECTIVES

"Enhanced recovery after surgery" (ERAS) protocols use a multisystem approach to target homeostatic physiology via opioid-minimizing analgesia. The aim of this study is to determine if an ERAS protocol for lower extremity bypass surgery improves pain control and decreases narcotics.

METHODS

From July 2020 through June 2021, all patients that underwent infrainguinal lower extremity bypass procedures were subject to the ERAS protocol and compared to a "pre-ERAS" group between June 2016 through May 2020. Preoperatively, ERAS patients were given celecoxib, gabapentin, and acetaminophen while postoperatively they were given standing acetaminophen, gabapentin, ketorolac, and tramadol with as needed use of oxycodone. Pain scores were recorded using a numerical rating pain scale. Demographics, length of stay, 30-day complications, and disposition metrics were recorded.

RESULTS

There were 50 patients in the ERAS group, compared to 114 before its implementation. The mean age was 70.5 (ERAS group) versus 68.7 (pre-ERAS group) and a majority were male (P > .05). Enhanced recovery after surgery patients were less likely to have chronic kidney disease (P = .01). Enhanced recovery after surgery patients had improved length of stay (3.6 ± 2.3 days vs 4.8 ± 3.2 days, ERAS vs pre-ERAS, P = .01). There was no significant difference between groups for the remaining demographics (P > .05). One patient (2%) in the ERAS group used patient-controlled analgesia, compared to 30 patients (26%) in the pre-ERAS group (P < .001). Cumulative pain control in the first 12 hours was significantly better in the ERAS group (P = .05). Pain control at discharge was similar between the 2 groups (3 pain score vs 3 pain score, pre-ERAS vs ERAS, P > .05).

CONCLUSION

Our study utilized a multisystem approach to optimize the physiologic stress response to vascular surgery while reducing high potency narcotic use. We show that an ERAS protocol provides noninferior pain control with less potent pain medication and improves the length of stay for patients undergoing infrainguinal bypass surgery.

Postoperative opioid prescribing patterns in the geriatric patient population

BACKGROUND

Opioid prescription patterns in elderly patients undergoing general surgery are not well characterized. The purpose of this study was to identify trends in postoperative opioid prescriptions in geriatric patients undergoing general surgery procedures and determine prescribing differences between the geriatric and non-geriatric patient population.

METHODS

We retrospectively evaluated geriatric and non-geriatric patients undergoing the most frequently performed open and laparoscopic general surgery procedures at our institution from 2014 to 2019. Differences in opioid prescriptions between the groups were analyzed.

RESULTS

We identified 5874 non-geriatric and 3306 geriatrics patients who underwent the included procedures at our institution. 5169 (88.0%) of non-geriatric patients and 2692 (81.4%) of geriatric patients received a perioperative opioid prescription. While the vast majority of both groups were prescribed opioids, geriatric patients were less likely to receive an opioid prescription (p < 0.0001). Between 2016 and 2019, the amount of opioid prescribed in the geriatric population decreased each year (p < 0.0001). Prescription amounts were significantly higher in geriatric patients aged 65-74 compared to patients 85 or older (p < 0.0001).

CONCLUSIONS

Individuals older than 65 years of age represent a growing percent of the population and there is a need to better understand opioid prescribing practices in this complex patient group. Postoperative opioid prescribing patterns differ significantly between the geriatric and non-geriatric patient population and warrant further investigation.

Age-related Opioid Exposure in Trauma: A Secondary Analysis of the Multimodal Analgesia Strategies for Trauma (MAST) Randomized Trial

OBJECTIVE

Evaluate the effect of age on opioid consumption after traumatic injury.

SUMMARY BACKGROUND DATA

Older trauma patients receive fewer opioids due to decreased metabolism and increased complications, but adequacy of pain control is unknown. We hypothesized that older trauma patients require fewer opioids to achieve adequate pain control.

METHODS

A secondary analysis of the multimodal analgesia strategies for trauma Trial evaluating the effectiveness of 2 multimodal pain regimens in 1561 trauma patients aged 16 to 96 was performed. Older patients (≥55 years) were compared to younger patients. Median daily oral morphine milligram equivalents (MME) consumption, average numeric rating scale pain scores, complications, and death were assessed. Multivariable analyses were performed.

RESULTS

Older patients (n = 562) had a median age of 68 years (interquartile range 61-78) compared to 33 (24-43) in younger patients. Older patients had lower injury severity scores (13 [9-20] vs 14 [9-22], P = 0.004), lower average pain scores (numeric rating scale 3 [1-4] vs 4 [2-5], P < 0.001), and consumed fewer MME/day (22 [10-45] vs 52 [28-78], P < 0.001). The multimodal analgesia strategies for trauma multi-modal pain regimen was effective at reducing opioid consumption at all ages. Additionally, on multivariable analysis including pain score adjustment, each decade age increase after 55 years was associated with a 23% reduction in MME/day consumed.

CONCLUSIONS

Older trauma patients required fewer opioids than younger patients with similar characteristics and pain scores. Opioid dosing for post-traumatic pain should consider age. A 20 to 25% dose reduction per decade after age 55 may reduce opioid exposure without altering pain control.

Perioperative Pain Management Issues Unique to Older Adults Undergoing Surgery: A Narrative Review

INTRODUCTION

The older population is growing and with this growth there is a parallel rise in the operations performed on this vulnerable group. The perioperative pain management strategy for older adults is unique and requires a team-based approach for provision of high-quality surgical care.

METHODS

Literature search was performed using PubMed in addition to review of relevant protocols and guidelines from geriatric, surgical, and anesthesia societies. Systematic reviews and meta-analyses, randomized trials, observational studies, and society guidelines were summarized in this review.

MANAGEMENT

The optimal approach to a pain management strategy for older adults undergoing surgery involves addressing all phases of perioperative care. For example, preoperative assessment of a patient's cognitive function and presence of chronic pain may impact the pain management plan. Consideration should be also given to intraoperative strategies to improve pain control and minimize both the dose and side effects from opioids (e.g. regional anesthetic techniques). Postoperative pain control (e.g. under or over treatment of pain) may impact the development of elderly-specific complications such as postoperative delirium and functional decline. Finally, pain management does not stop after the older adult patient leaves the hospital. Both discharge planning and post-operative clinic follow-up provide important opportunities for collaboration and intervention.

CONCLUSIONS

An opioid-sparing pain management strategy for older adults can be accomplished with a comprehensive and collaborative interdisciplinary strategy addressing all phases of perioperative care.

HTX-011 effectively reduces postoperative pain intensity and opioid use in the elderly

Aim: HTX-011 (ZYNRELEF™) is an extended-release, dual-acting local anesthetic containing bupivacaine and meloxicam. In bunionectomy and herniorrhaphy studies, HTX-011 resulted in less postoperative pain and less opioid consumption versus bupivacaine HCl. Here we evaluate HTX-011 in patients aged ≥65 years. Materials & methods: Patients received placebo, bupivacaine HCl or HTX-011 following surgery. End points included pain intensity, total opioid consumption, opioid-free patients and safety. Results: HTX-011-treated patients reported lower postoperative pain through 72 h versus bupivacaine HCl and placebo. Elderly patients administered HTX-011 used fewer opioids versus bupivacaine HCl, and a greater proportion remained opioid-free through 72 h. HTX-011 was well tolerated with a safety profile similar to bupivacaine HCl and placebo. Conclusion: HTX-011 maintained effectiveness and was well tolerated in elderly patients. Clinical Trial Registration: NCT03295721 and NCT03237481.

Study protocol: randomized controlled trial of opioid-free vs. traditional perioperative analgesia in elective orthopedic surgery

BACKGROUND

The medical community is beginning to recognize the contribution of prescription opioids in the growing national opioid crisis. Many studies have compared the safety and efficacy of alternative analgesics to opioids, but none utilizing a completely opioid-free perioperative protocol in orthopedics.

METHODS

We developed and tested an opioid-free perioperative analgesic pathway (from preoperative to postoperative period) among patients undergoing common elective orthopedic procedures. Patients will be randomized to receive either traditional opioid-including or completely opioid-free perioperative medications. This study is being conducted across multiple orthopedic subspecialties in patients undergoing the following common elective orthopedic procedures: single-level or two-level ACDF/ACDA, 1st CMC arthroplasty, Hallux Valgus/Rigidus corrections, diagnostic knee arthroscopies, total hip arthroplasty (THA), and total shoulder arthroplasty/reverse total shoulder arthroplasty (TSA/RTSA). The primary outcome measure is pain score at 24 h postoperatively. Secondary outcome measures include pain scores at additional time points, medication side effects, and several patient-reported variables such as patient satisfaction, quality of life, and functional status.

DISCUSSION

We describe the methods for a feasibility randomized controlled trial comparing opioid-free perioperative analgesics to traditional opioid-including protocols. We present this study so that it may be replicated and incorporated into future studies at other institutions, as well as disseminated to additional orthopedic and/or non-orthopedic surgical procedures. The ultimate goal of presenting this protocol is to aid recent efforts in reducing the impact of prescription opioids on the national opioid crisis.

TRIAL REGISTRATION

The protocol was approved by the local institutional review board and registered with clinicaltrials.gov (Identifier: NCT04176783 ) on November 25, 2019, retrospectively registered.

Practice Patterns in Perioperative Nonopioid Analgesic Administration by Anesthesiologists in a Veterans Affairs Hospital

OBJECTIVE

Although multimodal analgesia (MMA) is recommended for perioperative pain management, previous studies have found substantial variability in its utilization. To better understand the factors that influence anesthesiologists' choices, we assessed the associations between patient or surgical characteristics and number of nonopioid analgesic modes received intraoperatively across a variety of surgeries in a university-affiliated Veteran Affairs hospital.

METHODS

We included elective inpatient surgeries (orthopedic, thoracic, spine, abdominal, and pelvic procedures) that used at least one nonopioid analgesic within a one-year period. Multivariable multinomial logistic regression models were used to estimate adjusted odds ratios and 95% confidence intervals (CIs). We also described the combinations of analgesia used in each surgical subtype and conducted exploratory analyses to test the associations between the number of modes used and postoperative outcomes.

RESULTS

Of the 1,087 procedures identified, 33%, 53%, and 14% were managed with one, two, and three or more modes, respectively. Older patients had lower odds of receiving three or more modes (adjusted odds ratio [aOR] = 0.28, 95% confidence interval [CI] = 0.15-0.52), as were patients with more comorbidities (two modes: aOR = 0.87, 95% CI = 0.79-0.96; three or more modes: aOR = 0.81, 95% CI = 0.71-0.94). Utilization varied across surgical subtypes P < 0.0001). Increasing the number of modes, particularly use of regional anesthesia, was associated with shorter length of stay.

CONCLUSIONS

Our study suggests that age, comorbidities, and surgical type contribute to variability in MMA utilization. Risks and benefits of multiple modes should be carefully considered for older and sicker patients. Future directions include developing patient- and procedure-specific perioperative MMA recommendations.

Chronic Post-Surgical Pain in the Frail Older Adult

Older adults are the fastest growing segment of the population and surgical procedures in this group increase each year. Chronic post-surgical pain is an important consideration in the older adult as it affects recovery, physical functioning, and overall quality of life. It is increasingly recognized as a public health issue but there is a need to improve our understanding of the disease process as well as the appropriate treatment and prevention. Frailty, delirium, and cognition influence post-operative outcomes in older adults and have been implicated in the development of chronic post-surgical pain. Further research must be conducted to fully understand the role they play in the occurrence of chronic post-surgical pain in the older adult. Additionally, careful attention must be given to the physiologic, cognitive, and comorbidity differences between the older adult and the general population. This is critical for elucidating the proper chronic post-surgical pain treatment and prevention strategies to ensure that the older adult undergoing surgical intervention will have an appropriate and desirable post-operative outcome.

Perioperative Analgesia for Sinus and Skull-Base Surgery

Perioperative analgesic management is multifaceted, and an individualized approach should be taken with each patient. Preoperative discussion of the plan for pain control and the patient's postoperative expectations is a necessary facet for optimal outcomes of analgesia. There is the potential for significant abuse and development of dependence on opioids. Nonopioids, such as nonsteroidal anti-inflammatory drugs, acetaminophen, and gabapentinoids, provide reliable alternatives for analgesic management following sinus and skull-base surgery. There is a paucity of literature regarding perioperative pain regimens for sinus and skull-base surgery, and the authors hope that this review serves as a valuable tool for otolaryngologists.

Potential Opioid-Related Adverse Drug Events Are Associated With Decreased Revenue in Hip Replacement Surgery in the Older Population

Introduction

Opioid-related adverse drug events (ORADEs) are an increasingly recognized complication associated with the common prescription of opioids after orthopedic surgery. In this study, we attempted to understand how potential ORADEs following hip replacement surgery in older patients affected hospital length of stay, hospital revenue, and their association with specific risk factors and clinically relevant diseases occurring during hospitalization.

Methods

We conducted a retrospective study using the Centers for Medicare and Medicaid Services Administrative Database to analyze Medicare discharges after hip replacement surgery to identify potential ORADEs. The impact of potential ORADEs on mean hospital length of stay (LOS) and hospital revenue was analyzed.

Results

The potential ORADE rate in patients who underwent hip replacement surgery was 8.6%. The mean LOS for discharges with a potential ORADE was 1.41 days longer than that for discharges without an ORADE. The mean hospital revenue per day with a potential ORADE was US$1708 less than without an ORADE. Potential ORADEs were also found to be strongly associated with poor patient outcomes such as pneumonia, septicemia, and shock.

Discussion

Potential ORADEs in hip replacement surgery in older patients are associated with longer hospitalizations, decreased hospital revenue per day, certain patient risk factors, and clinically relevant diseases occurring during hospitalizations. Our finding of an association between potential ORADEs and decreased hospital revenue per day may be attributed to the management of these adverse events, as a patient may need to undergo additional testing, may need additional treatment regimens, and may need a higher level of care.

Conclusion

By reducing the use of opioids and employing a multimodal analgesic approach, we may improve patient care, decrease hospital lengths of stay, and increase hospital revenue.

Perioperative care of geriatric patients

The older population is expected to nearly double across the globe by 2050, and the baby boom cohort is expected to represent at least 20% of the US population by 2030. Geriatric patients will increasingly utilize the health-care system, and therefore surgical and perioperative care must be tailored to this sensitive group given the increased risk for perioperative complications. The literature was reviewed to highlight fundamental components of the preoperative evaluation as well as cardiac, pulmonary, and renal complications. Frailty is a multidimensional process that can lead to the physiologic effects of aging and estimates the risk of perioperative morbidity and mortality better than chronologic age alone. Health-care providers should assess a geriatric patient's cognitive status, decision-making capacity, frailty, advance care planning, medications, and anesthetic approach in a multidisciplinary fashion to ensure optimal care. The risks of postoperative cardiac, pulmonary, and renal complications should be evaluated and optimized preoperatively to reduce the potential for adverse outcomes.

Emergency Orthogeriatrics: Concepts and Therapeutic Considerations for the Geriatric Patient

Appropriate recognition of the physiologic, psychological, and clinical differences among geriatric patients, with respect to orthopedic injury and disease, is paramount for all emergency medicine providers to ensure they are providing high-value care for this vulnerable population.

Acute Pain in Older Adults: Recommendations for Assessment and Treatment

The management of acute pain in older adults (age 65 or greater) requires special attention due to various physiologic, cognitive, functional, and social issues that may change with aging. Especially in the postoperative setting, there are significant complications that can occur if pain is not treated adequately for elderly patients. In this article, the authors describe these changes in detail and discuss how pain should be assessed appropriately in older patients. In addition, the authors detail the unique risks and benefits of several mainstream analgesic medications as well as interventional treatments for elderly patients. The authors' goal is to provide recommendations for health care providers on appropriately recognizing and treating pain in a safe, effective manner for aging patients.

Opioid-free shoulder arthroplasty: a prospective study of a novel clinical care pathway

BACKGROUND

Opioid therapy has been a cornerstone of perioperative pain control for decades in the United States, despite our increased understanding of the morbidity and mortality linked to opioids. The purpose of this study is to explore the safety, efficacy, and feasibility of an entirely opioid-free perioperative pathway in patients undergoing elective shoulder arthroplasty.

METHODS

Thirty-five patients undergoing elective total shoulder arthroplasty with a mean age of 71 (range, 50-87) years elected into a comprehensive opioid-free, multimodal pain management protocol. Opioid use was completely eliminated for all points in the perioperative period including during regional and general anesthesia. Data were collected regarding patient-reported pain, opioid consumption in the perioperative period, postoperative delirium, nausea, constipation, and falls.

RESULTS

Pain level at the primary outcome point of 24 hours or discharge was rated at 2.5 on the numeric rating scale. Stable, low pain scores were demonstrated at all time points postoperatively. Low rates of nausea, falls, and constipation were reported. Only 1 patient required "rescue" opioid medications during the in-patient stay, and an additional patient was given a low-dose opioid prescription at the 2-week postoperative appointment.

CONCLUSIONS

An opioid-free, multimodal pain management pathway is a safe and effective option in properly selected patients undergoing shoulder arthroplasty with a very low risk of requiring rescue opioids. This study is the first such study to present a surgical protocol entirely free of opioids at all portions of the patient care pathway.

Surgical Risk Assessment and Prevention in Elderly Spinal Deformity Patients

Introduction:

Prevalence of adult deformity surgery in the elderly individuals continues to increase. These patients have additional considerations for the spine surgeon during surgical planning. We perform an informative review of the spinal and geriatric literature to assess preoperative and intraoperative factors that impact surgical complication occurrences in this population.

Significance:

There is a need to understand surgical risk assessment and prevention in geriatric patients who undergo thoracolumbar adult deformity surgery in order to prevent complications.

Methods:

Searches of relevant biomedical databases were conducted by a medical librarian. Databases searched included MEDLINE, Web of Science, CINAHL, IPA, Cochrane, PQ Health and Medical, SocINDEX, and WHO’s Global Health Library. Search strategies utilized Medical Subject Headings plus text words for extensive coverage of scoliosis and surgical technique concepts.

Results:

Degenerative scoliosis affects 68% of the geriatric population, and the rate of surgical interventions for this pathology continues to increase. Complications following spinal deformity surgery in this patient population range from 37% to 62%. Factors that impact outcomes include age, comorbidities, blood loss, and bone quality. Using these data, we summarize multimodal risk prevention strategies that can be easily implemented by spine surgeons.

Conclusions:

After evaluation of the latest literature on the complications associated with adult deformity surgery in geriatric patients, comprehensive perioperative management is necessary for improved outcomes. Preoperative strategies include assessing physiological age via frailty score, nutritional status, bone quality, dementia/delirium risk, and social activity support. Intraoperative strategies include methods to reduce blood loss and procedural time. Postoperatively, development of a multidisciplinary team approach that encourages early ambulation, decreases opiate use, and ensures supportive discharge planning is imperative for better outcomes for this patient population.

Effect of perioperative administration of dexmedetomidine on delirium after cardiac surgery in elderly patients: a double-blinded, multi-center, randomized study

Objective

Postoperative delirium (POD) is a serious complication in elderly patients undergoing cardiac surgery. This study was aimed at investigating the effect of perioperative administration of dexmedetomidine for general anesthesia maintenance on occurrence and duration of POD in elderly patients after cardiac surgery.

Methods

One hundred and sixty-four patients were enrolled after cardiac surgery between June 2009 and December 2016. Patients were assigned by a computer-generated randomization sequence in a 1:1 ratio to receive dexmedetomidine general anesthesia maintenance or propofol general anesthesia maintenance. POD was assessed every day with confusion assessment method for intensive care units (ICU) during the first 5 postoperative days.

Results

There was no significance in incidence of POD between the dexmedetomidine group and the propofol group (P=0.0758). In patients treated with dexmedetomidine, the median onset time of delirium was delayed (second day vs first day) and the duration of delirium reduced (2 days vs 3 days) when compared with propofol-treated patients. The dexmedetomidine-treated patients also displayed a lower VAS score and less opiate analgesic consumption. No difference was observed in respect to other postoperative outcomes.

Conclusion

For elderly patients, perioperative administration of dexmedetomidine reduced incidence, delayed onset and shortened duration of POD after cardiac surgery.

Safety of Injectable HPβCD-Diclofenac in Older Patients with Acute Moderate-to-Severe Postoperative Pain: A Pooled Analysis of Three Phase III Trials

BACKGROUND

Hydroxypropyl-β-cyclodextrin-diclofenac (HPβCD-diclofenac) is an NSAID used to treat acute moderate-to-severe postoperative pain. This post hoc analysis investigated the safety of HPβCD-diclofenac in patients aged ≥ 65 years.

METHODS

Data from three phase III trials of HPβCD-diclofenac in adult patients with acute moderate-to-severe postoperative pain were pooled (NCT00448110, NCT00507026, and NCT00726388). Patients who received one or more dose of HPβCD-diclofenac or placebo were included and stratified according to age: < 65, 65-74, or ≥ 75 years. Numerical and categorical variables were compared across the groups using ANOVA and Cochran-Mantel-Haenszel tests, respectively. Cochran-Mantel-Haenszel relative risks compared with placebo were calculated, adjusted by study.

RESULTS

Overall, 1289 patients were included: 878, 282, and 129 in the < 65, 65-74, and ≥ 75-years groups, respectively. Overall incidence of treatment-emergent adverse events (TEAEs) was similar in the three groups (p = 0.4360). Incidences of postoperative anemia (p < 0.0001), constipation (p = 0.0017), and hypotension (p = 0.0003) increased significantly across the age groups, whereas headache (p = 0.0008) and flatulence (p = 0.0118) decreased significantly. Relative risks for all System Organ Class categories and preferred terms investigated were similar among the groups and similar to placebo.

CONCLUSIONS

Overall incidence of TEAEs in patients aged 65-74 or ≥ 75 years was similar to patients aged < 65 years. The groups displayed similar relative risks for the most frequent TEAEs, which were all similar to placebo. The TEAE profiles of the groups showed differences, all of which may be anticipated due to age-related differences in susceptibility and the types of surgery most commonly performed in each group.

Pain in the Elderly: Identification, Evaluation, and Management of Older Adults with Pain Complaints and Pain-related Symptoms

Pain is a common and often underappreciated and undermanaged problem in older adults. This article addresses the scope of the issue of pain prevalence in older adults, types of pain and their characteristics, approach to and clinical workup of older adults with pain complaints and pain-related symptoms, nonpharmacologic and pharmacologic management strategies, and caveats with attention to medication side effects in the elderly.

Exploring Opioid-Sparing Multimodal Analgesia Options in Trauma: A Nursing Perspective

Challenges with opioids (e.g., adverse events, misuse and abuse with long-term administration) have led to a renewed emphasis on opioid-sparing multimodal management of trauma pain. To assess the extent to which currently available evidence supports the efficacy and safety of various nonopioid analgesics and techniques to manage trauma pain, a literature search of recently published references was performed. Additional citations were included on the basis of authors' knowledge of the literature. Effective options for opioid-sparing analgesics include oral and intravenous (IV) acetaminophen; nonsteroidal anti-inflammatory drugs available via multiple routes; and anticonvulsants, which are especially effective for neuropathic pain associated with trauma. Intravenous routes (e.g., IV acetaminophen, IV ketorolac) may be associated with a faster onset of action than oral routes. Additional adjuvants for the treatment of trauma pain are muscle relaxants and alpha-2 adrenergic agonists. Ketamine and regional techniques play an important role in multimodal therapy but require medical and nursing support. Nonpharmacologic treatments (e.g., cryotherapy, distraction techniques, breathing and relaxation, acupuncture) supplement pharmacologic analgesics and can be safe and easy to implement. In conclusion, opioid-sparing multimodal analgesia addresses concerns associated with high doses of opioids, and many pharmacologic and nonpharmacologic options are available to implement this strategy. Nurses play key roles in comprehensive patient assessment; administration of patient-focused, opioid-sparing, multimodal analgesia in trauma; and monitoring for safety concerns.

The Efficacy and Safety of the Fentanyl Iontophoretic Transdermal System (IONSYS®) in the Geriatric Population: Results of a Meta-Analysis of Phase III and IIIb Trials

Background and Objectives

Acute postoperative pain management in the geriatric patient can be challenging, including their response to medications. The purpose of this analysis was to evaluate whether the efficacy and safety profile of fentanyl iontophoretic transdermal system (ITS) (IONSYS^®) was similar in geriatric (≥65 years) and non-geriatric (<65 years) patients.

Methods

Efficacy and safety data from three randomized, double-blind, placebo-controlled trials and four randomized, open-label, active-comparator trials were utilized for this analysis. Efficacy was assessed via the patient global assessment (PGA) and the investigator global assessment (IGA) scales. The PGA and IGA are categorical 4-point scales (excellent, good, fair, or poor) with treatment success defined as excellent or good. Safety was evaluated via adverse events.

Results

A total of 1763 patients were assigned to the fentanyl ITS treatment group. Of the 1763 patients in the fentanyl ITS group, 499 patients were ≥65 years of age; 65.1% were 65–74 years of age, 31.7% were 75–84 years of age, and 3.2% were ≥85 years of age. In the fentanyl ITS treatment groups, there were no statistically significant differences between the non-geriatric and geriatric patients in terms of patients reporting success on the PGA at 24 h (80.0 vs. 83.0%, respectively; p = 0.3415). There were no statistically significant differences between the groups in success rates on the IGA at study discharge (82.8 vs. 87.5%, respectively; p = 0.1195). The safety profile was similar between the age groups.

Conclusions

Overall, efficacy and safety of the fentanyl ITS were similar between the geriatric and non-geriatric patients.

Pharmacologic Considerations of Anesthetic Agents in Geriatric Patients

Aging is a natural process of declining organ function and reserve. Census data show that the geriatric population is expected to grow to nearly 30%. More than half of geriatric patients have 1 or more surgical procedures in their lifetimes. Moreover, this is the population at greatest risk of morbidity and mortality with any given complication. There is remarkable variability in health across the age spectrum, from fit to frail and compromised. This variability requires a unique approach to anesthetic delivery and drug dosing on an individual basis to avoid complications such as postoperative cognitive dysfunction and delirium.

Pain in the Elderly

Pain management in the elderly has increasingly become problematic in the USA as the aged population grows. The proportion of the population over 65 continues to climb and may eclipse 20 % in the next decade. In order to effectively diagnosis and treat these patients, a proper history and physical exam remain essential; pain assessment scales such as the Verbal Descriptor Scales (VDS), the Numerical Rating Scales (NRS), and the Visual Analogue Scales (VAS) often but not always prove beneficial. The conditions most frequently afflicting this population include osteoarthritis, diabetic neuropathy, post-herpetic neuralgia, and lower back pain which include spondylosis and radiculopathies. While the normal aging process does not necessarily guarantee symptoms of chronic pain, elderly individuals are far more likely to develop these painful conditions than their younger counterparts. There are many effective treatment modalities available as potential therapeutic interventions for elderly patients, including but not limited to analgesics such as NSAIDs and opioids, as well as multiple interventional pain techniques. This review will discuss chronic pain in the elderly population, including epidemiology, diagnostic tools, the multitude of co-morbidities, and common treatment modalities currently available to physicians.

Opioidergic effects on enteric and sensory nerves in the lower GI tract: basic mechanisms and clinical implications

Opioids are one of the most prescribed drug classes for treating acute pain. However, chronic use is often associated with tolerance as well as debilitating side effects, including nausea and dependence, which are mediated by the central nervous system, as well as constipation emerging from effects on the enteric nervous system. These gastrointestinal (GI) side effects limit the usefulness of opioids in treating pain in many patients. Understanding the mechanism(s) of action of opioids on the nervous system that shows clinical benefit as well as those that have unwanted effects is critical for the improvement of opioid drugs. The opioidergic system comprises three classical receptors (μ, δ, κ) and a nonclassical receptor (nociceptin), and each of these receptors is expressed to varying extents by the enteric and intestinal extrinsic sensory afferent nerves. The purpose of this review is to discuss the role that the opioidergic system has on enteric and extrinsic afferent nerves in the lower GI tract in health and diseases of the lower GI tract, particularly inflammatory bowel disease and irritable bowel syndrome, and the implications of opioid treatment on clinical outcomes. Consideration is also given to emerging developments in our understanding of the immune system as a novel source of endogenous opioids and the mechanisms underlying opioid tolerance, including the potential influence of opioid receptor splice variants and heteromeric complexes.
