Kim JH, Sohn JH, Lee JJ, Kwon YS. Age-Related Variations in Postoperative Pain Intensity across 10 Surgical Procedures: A Retrospective Study of Five Hospitals in South Korea. J Clin Med 2023; 12:5912. [PMID: 37762853 PMCID: PMC10532067 DOI: 10.3390/jcm12185912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/08/2023] [Accepted: 09/08/2023] [Indexed: 09/29/2023] Open
Abstract
Age-related differences in pain perception have been reported in various contexts; however, their impact on postoperative pain intensity remains poorly understood, especially across different surgical procedures. Data from five hospitals were retrospectively analyzed, encompassing patients who underwent 10 distinct surgical procedures. Numeric rating scale scores were used to assess the worst postoperative pain intensity during the 24 h after surgery. The multivariate linear regression model analyzed the relationship between age and pain intensity. Subgroup analyses were performed according to sex and patient-controlled analgesia (PCA). This study included 41,187 patients. Among the surgeries studied, lumbar spine fusion (β = -0.155, p < 0.001) consistently and significantly exhibited a decrease in worst postoperative pain with increasing age. Similar trends were observed in cholecystectomy (β = -0.029, p < 0.001) and several other surgeries; however, the results were inconsistent across all analyses. Surgeries with higher percentages of PCA administration had lower median worst-pain scores. In conclusion, age may affect postoperative pain intensity after specific surgeries; however, a comprehensive understanding of the complex interplay between age, surgical intervention, and pain intensity is required. Pain management strategies should consider various factors, including age-related variations.

Pain severity and pharmacologic pain management among community-living older adults: the MOBILIZE Boston study. Aging Clin Exp Res 2017; 29:1139-1147. [PMID: 28224474 DOI: 10.1007/s40520-016-0700-9] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2016] [Accepted: 12/15/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Concerns about polypharmacy and medication side effects contribute to undertreatment of geriatric pain. This study examines use and effects of pharmacologic treatment for persistent pain in older adults. METHODS The MOBILIZE Boston Study included 765 adults aged ≥70 years, living in the Boston area, recruited from 2005 to 2008. We studied 599 participants who reported chronic pain at baseline. Pain severity, measured using the Brief Pain Inventory (BPI) severity subscale, was grouped as very mild (BPI <2), mild (BPI 2-3.99), and moderate to severe (BPI 4-10). Medications taken in the previous 2 weeks were recorded from medication bottles in the home interview. RESULTS Half of participants reported using analgesic medications in the previous 2 weeks. Older adults with moderate to severe pain were more likely to use one or more analgesic medications daily than those with very mild pain (49 versus 11%, respectively). The most commonly used analgesic was acetaminophen (28%). Opioid analgesics were used daily by 5% of participants. Adjusted for health and demographic factors, pain severity was strongly associated with daily analgesic use (moderate-severe pain compared to very mild pain, adj. OR 7.19, 95% CI 4.02-12.9). Nearly one third of participants (30%) with moderate to severe pain felt they needed a stronger pain medication while 16% of this group were concerned they were using too much pain medication. CONCLUSION Serious gaps persist in pain management particularly for older adults with the most severe chronic pain. Greater efforts are needed to understand barriers to effective pain management and self-management in the older population.

Abstract
BACKGROUND The acute recovery phase after hip fracture surgery is often complicated by severe pain, postoperative blood loss with subsequent transfusion, and delirium. Prevalent comorbidity in hip fracture patients limit the use of opioid-based analgesic therapies, yielding a high risk for inferior pain treatment. Postoperative cryotherapy is suggested to provide an analgesic effect, and to reduce postoperative blood loss. In this prospective, open-label, parallel, multicentre, randomized controlled, clinical trial, we aimed to determine the efficacy of continuous-flow cryocompression therapy (CFCT) in the acute recovery phase after hip fracture surgery. METHODS Patients with an intra or extracapsular hip fracture scheduled for surgery were included. Subjects were allocated to receive postoperative CFCT or usual care. The primary endpoint was numeric rating scale (NRS) pain the first 72 postoperative hours. Secondly, analgesic use; postoperative haemoglobin change and transfusion incidence; functional outcome; length of stay; delirium incidence; location of rehabilitation; patient-reported health outcome; complications and feasibility were assessed. RESULTS Sixty-one subjects in the control group, and 64 subjects in the CFCT group were analysed. Within the CFCT group, post treatment NRS pain declined 0.31 (p=0.07) at 24h, 0.28 (p=0.07) at 48h, and 0.47 (p=0.002) at 72h relative to pre treatment NRS pain. Sensitivity analysis at 72h showed that NRS pain was 0.92 lower in the CFCT group when compared to the control group (1.50 vs. 2.42; p=0.03). Postoperative analgesic use was comparable between groups. Between postoperative day one and three haemoglobin declined 0.29mmol/l in the CFCT group and 0.51mmol/l in controls (p=0.06), and transfusion incidence was comparable. The timed up and go test and length of stay were also comparable between both groups. Complications, amongst delirium and cryotherapy-related adverse events were not statistically significantly different. Discharge locations did not differ between groups. At outpatient follow-up subjects did not differ in patient-reported health outcome scores. Subjects rated CFCT satisfaction with an average of 7.1 out of 10 points. CONCLUSIONS No evidence was recorded to suggest that CFCT has an added value in the acute recovery phase after hip fracture surgery. If patients complete the CFCT treatment schedule, a mild analgesic effect is observed at 72h.

Abstract
Objectives: To evaluate the safety and effectiveness of once-daily gastroretentive gabapentin (G-GR) for the treatment of postherpetic neuralgia in real-world clinical practice. Materials and Methods: Patients aged 18 years and above were divided into 2 cohorts: patients aged 70 years and below and patients above 70 years. All patients were titrated to 1800 mg G-GR/d over 2 weeks and maintained at that dosage for 6 weeks, for 8 weeks total treatment. To reflect clinical practice, exclusion criteria were limited to those in the product label. Efficacy was assessed using a visual analog scale (VAS) and the Brief Pain Inventory. Patient/Clinician Global Impression of Change scales were completed at week 8. Adverse events (AEs) were assessed. Results: The efficacy population included 190 patients (110, 70 y and below; 80, above 70 y). The mean percent change in VAS score at week 8 from baseline was −21.3%/−20.4% (70 y and below/above 70 y). The proportion of patients with a ≥30% reduction in VAS score from baseline was 51.8%/55.0% (70 y and below/above 70 y) and was 42.7%/37.5% for a ≥50% reduction. Brief Pain Inventory scores were all significantly reduced by week 8. On the Patient Global Impression of Change instrument, more patients aged 70 years and below reported feeling “much” or “very much” improved from baseline (59.0% vs. 40.3%). G-GR was generally well tolerated. Thirty-seven (18.8%) patients experienced AEs that led to discontinuation. No patients died and 5 (2.5%) patients experienced serious AEs. The most common G-GR-related AEs (70 y and below/above 70 y) were dizziness (11.7%/16.3%) and somnolence (3.6%/8.1%). Discussion: In real-world clinical practice, G-GR seems to be an effective, well-tolerated treatment option for patients with postherpetic neuralgia, regardless of age.

Abstract
As key players in multidisciplinary health care systems, geriatric social workers must understand the dynamics of pain management among older adults with chronic pain. This study identified perceived barriers to, and facilitators for, utilizing nonpharmacological pain management through face-to-face interviews with 44 ethnically diverse community-dwelling older adults. Constant comparative analysis identified barriers not recognized in prior studies: (a) embarrassment/self-consciousness, (b) unavailability of certain treatments, and (c) lack of faith in effectiveness of nonpharmacological treatments. Most frequently reported facilitators were (a) social support, (b) positive attitude, and (c) available resources. Social workers can provide counseling to motivate older adults to exercise to manage chronic pain and refer them to exercise programs tailored for older adults. To resolve the most frequently reported barrier-transportation-social workers can link older adults with transportation services offered by senior centers or other nonprofit agencies.

Abstract
There are contradictory data regarding older individuals' sensitivity to pain stimulation and opioid administration. Adult (12-16 months; n = 10) and aged (27-31 months; n = 7) male F344xBN rats were tested in a thermal sensitivity procedure where the animal chooses to remain in one of two compartments with floors maintained at various temperatures ranging from hot (45°C) through neutral (30°C) to cold (15°C). Effects of morphine were determined for three temperature comparisons (ie, hot/neutral, cold/neutral, and hot/cold). Aged rats were more sensitive to cold stimulation during baseline. Morphine produced antinociception during hot thermal stimulation, but had no effect on cold stimulation. The antinociceptive (and locomotor-altering) effects of morphine were attenuated in aged rats. These data demonstrate age-related differences in baseline thermal sensitivity and responsiveness to opioids. Based on behavioral and physiological requirements of this procedure, it is suggested that thermal sensitivity may provide a relevant animal model for the assessment of pain and antinociception.

Abstract
Chronic pain occurs in 45-85% of the geriatric population and the need to treat chronic pain is growing substantially. Unfortunately, treatment for chronic pain is not always correctly targeted, which leads to a reduced quality of life, with decreased socialization, depression, sleep disturbances, cognitive impairment, disability and malnutrition. Considering these consequences, healthcare professionals should aim at improving the diagnosis and treatment of chronic pain in older persons. One of the most important limitations in achieving successful pain management is that older people are not aware that pain management options exist or medications for pain, such as opioids, have associated benefits and adverse effects. Importantly, opioids do not induce any organ failure and if adequately used at the right dosage may only present some predictable and preventable adverse effects. Treating and controlling chronic pain is essential in elderly patients in order to maintain a good quality of life and an active role in both the family and society. To date there are only a few randomized clinical trials testing opioid therapy in elderly patients, and the aim of the present review is to highlight the efficacy and tolerability of opioid use through a literature search strategy in elderly people with chronic non-cancer pain.

Abstract
OBJECTIVE To review the management and follow-up of patients with minor thoracic injuries (MTI) treated by emergency or primary care physicians. DESIGN A multicentre, retrospective study. SETTING Three university-affiliated emergency departments of the metropolitan region of Quebec city, Que. PARTICIPANTS Patients older than 16 years of age with suspected or proven rib fractures following traumatic events. MAIN OUTCOME MEASURES Differences in admission and discharge proportions and disposition management following MTI. RESULTS Four hundred and forty-seven charts were analyzed. Only 23 patients (5.2%) were admitted during the study period. Admission and discharge proportions were significantly different among the 3 surveyed hospitals, ranging from 1.3% to 15.2% (P < or = .001). There were no recommendations of follow-up noted in most (53.5%) of the charts and there were no differences after hospital stratification. Planned follow-up visits were scheduled for 5.7% of discharged patients. Being older than 65 years of age or having multiple rib fractures had no influence on management and follow-up recommendations. Eighty-two patients (18.6%) had unplanned follow-up visits in the emergency department, with inadequate pain relief as the principal reason for consultation (56.1%). There was no significant difference after stratification for age and type of analgesia. Other clinically significant delayed complications were recorded in 8.3% of all MTI patients. CONCLUSION The proportion of patients admitted for rib fractures was lower than the expected 25%, based on previous publications, and varied across surveyed hospitals. A very low proportion of patients was offered planned follow-up visits or even any follow-up recommendations in view of possible delayed complications and disabilities. Further studies are needed to identify predictors of delayed MTI complications and enhance appropriate use of follow-up resources.

Abstract
SUMMARY OF CONSENSUS: 1. The use of opioids in cancer pain: The criteria for selecting analgesics for pain treatment in the elderly include, but are not limited to, overall efficacy, overall side-effect profile, onset of action, drug interactions, abuse potential, and practical issues, such as cost and availability of the drug, as well as the severity and type of pain (nociceptive, acute/chronic, etc.). At any given time, the order of choice in the decision-making process can change. This consensus is based on evidence-based literature (extended data are not included and chronic, extended-release opioids are not covered). There are various driving factors relating to prescribing medication, including availability of the compound and cost, which may, at times, be the main driving factor. The transdermal formulation of buprenorphine is available in most European countries, particularly those with high opioid usage, with the exception of France; however, the availability of the sublingual formulation of buprenorphine in Europe is limited, as it is marketed in only a few countries, including Germany and Belgium. The opioid patch is experimental at present in U.S.A. and the sublingual formulation has dispensing restrictions, therefore, its use is limited. It is evident that the population pyramid is upturned. Globally, there is going to be an older population that needs to be cared for in the future. This older population has expectations in life, in that a retiree is no longer an individual who decreases their lifestyle activities. The "baby-boomers" in their 60s and 70s are "baby zoomers"; they want to have a functional active lifestyle. They are willing to make trade-offs regarding treatment choices and understand that they may experience pain, providing that can have increased quality of life and functionality. Therefore, comorbidities--including cancer and noncancer pain, osteoarthritis, rheumatoid arthritis, and postherpetic neuralgia--and patient functional status need to be taken carefully into account when addressing pain in the elderly. World Health Organization step III opioids are the mainstay of pain treatment for cancer patients and morphine has been the most commonly used for decades. In general, high level evidence data (Ib or IIb) exist, although many studies have included only few patients. Based on these studies, all opioids are considered effective in cancer pain management (although parts of cancer pain are not or only partially opioid sensitive), but no well-designed specific studies in the elderly cancer patient are available. Of the 2 opioids that are available in transdermal formulation--fentanyl and buprenorphine--fentanyl is the most investigated, but based on the published data both seem to be effective, with low toxicity and good tolerability profiles, especially at low doses. 2. The use of opioids in noncancer-related pain: Evidence is growing that opioids are efficacious in noncancer pain (treatment data mostly level Ib or IIb), but need individual dose titration and consideration of the respective tolerability profiles. Again no specific studies in the elderly have been performed, but it can be concluded that opioids have shown efficacy in noncancer pain, which is often due to diseases typical for an elderly population. When it is not clear which drugs and which regimes are superior in terms of maintaining analgesic efficacy, the appropriate drug should be chosen based on safety and tolerability considerations. Evidence-based medicine, which has been incorporated into best clinical practice guidelines, should serve as a foundation for the decision-making processes in patient care; however, in practice, the art of medicine is realized when we individualize care to the patient. This strikes a balance between the evidence-based medicine and anecdotal experience. Factual recommendations and expert opinion both have a value when applying guidelines in clinical practice. 3. The use of opioids in neuropathic pain: The role of opioids in neuropathic pain has been under debate in the past but is nowadays more and more accepted; however, higher opioid doses are often needed for neuropathic pain than for nociceptive pain. Most of the treatment data are level II or III, and suggest that incorporation of opioids earlier on might be beneficial. Buprenorphine shows a distinct benefit in improving neuropathic pain symptoms, which is considered a result of its specific pharmacological profile. 4. The use of opioids in elderly patients with impaired hepatic and renal function: Functional impairment of excretory organs is common in the elderly, especially with respect to renal function. For all opioids except buprenorphine, half-life of the active drug and metabolites is increased in the elderly and in patients with renal dysfunction. It is, therefore, recommended that--except for buprenorphine--doses be reduced, a longer time interval be used between doses, and creatinine clearance be monitored. Thus, buprenorphine appears to be the top-line choice for opioid treatment in the elderly. 5. Opioids and respiratory depression: Respiratory depression is a significant threat for opioid-treated patients with underlying pulmonary condition or receiving concomitant central nervous system (CNS) drugs associated with hypoventilation. Not all opioids show equal effects on respiratory depression: buprenorphine is the only opioid demonstrating a ceiling for respiratory depression when used without other CNS depressants. The different features of opioids regarding respiratory effects should be considered when treating patients at risk for respiratory problems, therefore careful dosing must be maintained. 6. Opioids and immunosuppression: Age is related to a gradual decline in the immune system: immunosenescence, which is associated with increased morbidity and mortality from infectious diseases, autoimmune diseases, and cancer, and decreased efficacy of immunotherapy, such as vaccination. The clinical relevance of the immunosuppressant effects of opioids in the elderly is not fully understood, and pain itself may also cause immunosuppression. Providing adequate analgesia can be achieved without significant adverse events, opioids with minimal immunosuppressive characteristics should be used in the elderly. The immunosuppressive effects of most opioids are poorly described and this is one of the problems in assessing true effect of the opioid spectrum, but there is some indication that higher doses of opioids correlate with increased immunosuppressant effects. Taking into consideration all the very limited available evidence from preclinical and clinical work, buprenorphine can be recommended, while morphine and fentanyl cannot. 7. Safety and tolerability profile of opioids: The adverse event profile varies greatly between opioids. As the consequences of adverse events in the elderly can be serious, agents should be used that have a good tolerability profile (especially regarding CNS and gastrointestinal effects) and that are as safe as possible in overdose especially regarding effects on respiration. Slow dose titration helps to reduce the incidence of typical initial adverse events such as nausea and vomiting. Sustained release preparations, including transdermal formulations, increase patient compliance.
