Perioperative Care of Elderly Surgical Outpatients

Prescription Opioid Misuse in Older Adult Surgical Patients: Epidemiology, Prevention, and Clinical Implications

ABSTRACT

The United States and many other developed nations are in the midst of an opioid crisis, with consequent pressure on prescribers to limit opioid prescribing and reduce prescription opioid misuse. This review addresses prescription opioid misuse for older adult surgical populations. We outline the epidemiology and risk factors for persistent opioid use and misuse in older adults undergoing surgery. We also address screening tools and prescription opioid misuse prevention among vulnerable older adult surgical patients (e.g., older adults with a history of an opioid use disorder), followed by clinical management and patient education recommendations. A significant plurality of older adults engaged in prescription opioid misuse obtain opioid medication for misuse from health providers. Thus, nurses can play a critical role in identifying those older adults at a higher risk for misuse and deliver quality care while balancing the need for adequate pain management against the risk for prescription opioid misuse.

Is there a need for postoperative monitoring after open carpal tunnel release under WALANT?

Open carpal tunnel release (OCTR) under wide-awake local anesthesia with no tourniquet (WALANT) is a common outpatient procedure in hand surgery worldwide. In our clinic, WALANT has replaced intravenous regional anesthesia with a tourniquet (IVRA, or 'Bier block') as standard practice in OCTR. We therefore wondered what the optimal postoperative setting after OCTR under WALANT is. In this study, we compared patient satisfaction in two postoperative settings: immediate discharge (ID) after the operation, or short postoperative monitoring (PM) period in the outpatient clinic. Our hypothesis was that older patients would prefer a brief postoperative surveillance. We retrospectively analyzed patient satisfaction with the two settings using an adjusted questionnaire based on the standard Swiss grading system. We also assessed postoperative pain, satisfaction with the perioperative preparations and the reasons for unscheduled postoperative consultations, as secondary outcomes. One hundred and nine patients (ID, n = 63; PM, n = 46) were included in this single-center retrospective observational study. Patients were highly satisfied with both postoperative settings (Mean: ID 5.1/6; PM 5.5/6; p = 0.07). Even patients aged ≥80 years reported extremely high satisfaction with both settings (ID 5.6/6; PM 6.0/6; p = 0.08). Fifteen patients (ID, n = 11 [17.5%]; PM, n = 4 [8.7%], p = 0.72) unexpectedly consulted a doctor after surgery. OCTR under WALANT as an outpatient procedure with immediate discharge was associated with high patient satisfaction. However, detailed postoperative monitoring could contribute to the patient's well-being and education on how to cope with the postoperative course, and help with any questions.

Virtual respiratory therapy delivered through a smartphone app: a mixed-methods randomised usability study

INTRODUCTION

A new smartphone app (QUT Inspire) has been developed to detect inspiratory sound and deliver virtual incentive spirometry (ISy), a respiratory therapy technique used in postoperative recuperation, management of some chronic conditions and with potential applications in SARS-CoV-2 rehabilitation. The aim of this study was to compare the usability of this new app with a clinical ISy device as measured by effectiveness, efficiency and satisfaction.

METHODS

In this mixed-methods randomised usability study, healthy volunteers (aged 39.2±12.2 years, n=24) compared inspirations using the QUT Inspire app and a Triflo II clinical ISy device. A post-test questionnaire and a semi-structured interview explored dimensions of usability regarding the new app.

RESULTS

The duration of inspirations performed using the QUT Inspire app (7.3±2.0 s) were comparable with use of the Triflo II ISy device (7.5±2.3 s). No artefacts arising from the order of device testing were identified. App users held their phones adjacent but not proximal to their mouths (13.6±6.4 cm), notwithstanding instructions to keep the phone less than 5 cm away for optimal breath sound detection. The use of onscreen text or video instructional materials did not result in a significant reduction in this distance. Participants reported clear preferences for the app (100%, n=24) to motivate persistence with repeated inspirations. App gamification features such as a timer (75%, n=18) and breath counter (83.3%, n=20) were well regarded. Analysis of semi-structured interviews identified four main themes arising from this study: visual reward from responsive app animations, clinical look and feel influencing credibility, perceived effort affecting engagement and selective adoption of gamification features.

CONCLUSION

This study demonstrates that a virtual ISy app can be effective, efficient and have high satisfaction. Improvements informed by this research include use of additional phone sensors to optimise sound detection and minimising the distance that phones are held from the user's mouth. Further research in randomised controlled trials are needed to evaluate performance of this app in clinical contexts where ISy is currently employed.

Impact of chronic medications in the perioperative period: mechanisms of action and adverse drug effects (Part I)

Background: This review article discusses the pharmacology of the most commonly used chronic medications in patients undergoing elective surgical procedures. The mechanism of action and adverse side effects of cardiovascular medications (e.g., beta blockers, alpha-2 agonist, calcium channel blockers, ACE inhibitors, diuretics), lipid-lowering drugs, gastrointestinal medications (H2-blockers, proton pump inhibitors), pulmonary medications (inhaled β-agonists, anticholinergics,), antibiotics (tetracyclines, clindamycin and macrolide, linezolid), opioids and non-opioids analgesics (NSAIDs, COX-2 inhibitors, acetaminophen), gabapentanoids, erectile dysfunction (ED) drugs, and psychotropic drugs (tricyclic antidepressants [TCAs], monoamine oxidase inhibitors [MAOI], selective serotonin reuptake inhibitors [SSRIs], serotonin norepinephrine reuptake inhibitors [SNRIs], and cannabinol-containing drugs) will be reviewed.Materials and Methods: An online search was conducted from January 2000 through February 2021 with the Medline database through PubMed and Google Scholar using the following search terms/keywords: "chronic medications in the perioperative period", and "chronic medications and anesthetic implications." In addition, we searched for anesthetic side effects associated with the major drug groups.Results and Conclusions: An understanding of the pharmacology and pharmacokinetics of most used chronic medications is important to avoid untoward outcomes in the perioperative period. These drug interactions may result in altered efficacy and toxicity of the anesthetic medications administered during surgery. These drug-drug interactions can also effect the morbidity, mortality, and recovery time of surgical patients. Part I of this two-part review article focuses on the mechanisms of action and adverse side effects of the chronic medications most commonly taken by surgical patients in the preoperative period.

Anaesthesia for the elderly: a narrative review

As octogenarians in the operation room are no longer an exemption but the norm, perioperative management needs to be adopted to meet the special requirements of this group of patients. Anaesthesia does not need to be re-invented to fit the elderly. However, as elderly patients are among those most affected by adverse postoperative outcomes, the same diligence that is as a matter of course exercised in anaesthesiologic care of the youngest patients needs to be exercised for the eldest as well. Aging is associated with characteristic physiologic changes and an overall reduction in compensation width. However, the individual relevance of these changes varies distinctly. A comprehensive preoperative assessment is therefore essential to identify those at high risk. Maintaining functionality and preventing cognitive decline are central elements of perioperative care for frail elders, often only requiring unspectacular, but effective adjustments to established routine care processes. This review focuses on current recommendations in the perioperative anaesthesiologic management of elderly patients with a view towards assisting clinical anaesthesiologists in implementing respective structures in their setting and adjusting care pathways to meet the needs of this vulnerable but growing group of patients and improve their postoperative outcome.

Opioid Stewardship in Orthopaedic Surgery: Principles and Practice

The abuse of prescription opioid pain medication has contributed to the U.S. opioid crisis. Opioid stewardship programs ensure that our patients receive the safest and most effective opioid regimens. Opioid stewardship programs involve a multidisciplinary team, including pharmacists, orthopaedic surgeons, nurses, pain management personnel, and anesthesiologists. All of these stakeholders work together to formulate the best evidence-based use of these medications.

Opioid Use and Pain Control in the Elderly After Elective or Urgent Orthopaedic Surgery: A Retrospective Cohort Study

BACKGROUND

As an increasing number of elderly are undergoing orthopaedic procedures, it is important to understand and evaluate postoperative pain management in this population, especially in regard to opioid use. Data in the literature pertaining to the very elderly remains scarce.

OBJECTIVES

This study was conducted to evaluate whether older patients require lower opioid doses than their younger counterparts after undergoing an elective or urgent orthopaedic procedure, and to assess the cumulative incidence of adverse events and length of stay for each age group.

METHODS

A retrospective cohort study was performed to compare the mean opioid use and pain control between two groups of elderly patients (65-79 years and ≥ 80 years of age). The study included 250 patients who underwent either an elective arthroplasty or urgent orthopaedic surgery following a fracture. Data were collected during the 7 days following surgery.

RESULTS

No significant difference was found in mean and maximal pain scores between the two groups. Opioid use (expressed in intravenous morphine equivalents) was higher in the younger group. The difference reached statistical significance on the first postoperative day (subjects 65-79 years of age taking 21.3 mg, vs. 10.9 mg for the group over 80 years of age; mean difference 10.3 mg, 95% confidence interval 1.3-19.4). This was also observed in patients undergoing elective surgery on postoperative days 1, 5, 6 and 7. No difference in opioid use was observed between age groups in patients undergoing urgent surgery. Acute cognitive status deterioration, delirium, oxygen desaturation and constipation were observed more frequently in the older group, while mean length of stay was higher in the older group undergoing urgent surgery (8 vs. 17 days, p < 0.001).

CONCLUSIONS

Our findings further support age-related differences in opioid requirements during the postoperative context after elective orthopaedic surgery, while no difference was found between age groups after urgent surgery.

[Efficiency of the multimodal approach to analgesia in total knee arthroplasty]

MATERIAL AND METHODS

The study included 160 patients with end stage knee osteoarthritis hospitalized for primary uncomplicated TKA. There were 142 women and 18 men (mean age 66.5 and 65.4 years respectively). In the control group (n=100) standard protocol of perioperative pain management was applied, in the main group (n=60) - original multimodal approach including patient's education in order to increase his awareness and to reduce anxiety on the preoperative stage, modified surgical technique (optimization of incision length, 'sliding window' principle, tourniquet during the whole procedure until applying of compressive dressing, no drains and local infiltration analgesia) and double-level postoperative analgesia. Different factors of pain syndrome were assessed before surgery by using of specialized tests, while the dynamics of early postoperative pain characteristics were evaluated by individual diaries.

RESULTS

Despite decrease of pain syndrome in both groups within 3 days after TKA in the main group these changes were significantly better (p<0.05). On the first postoperative day 42 (70%) patients in the main group had not pain at rest, while in the control group such cases were absent (р<0.001). There was 2-fold increase of hours of moderate/severe pain per day in the control group compared with the main group (р<0.001). No specific complications were identified in both groups during follow-up.

CONCLUSION

Original multimodal perioperative approach to analgesia proved its efficiency in patients undergoing primary TKA compared with conventional one and may be safely used in clinical practice.
