Sex differences in psychotropic and analgesic drug use before and after initiating treatment with acetylcholinesterase inhibitors.

Background/aimsThe aim was to explore the impact of sex on prevalence, patterns and trends in the prescription of psychotropics and analgesics in users of acetylcholinesterase inhibitors (AChEIs), before and after AChEI initiation, compared to the general population.MethodsA prospective study applying data from the Norwegian Prescription Database (NorPD) in the period 2004–2016. Prescription of antidepressants, antipsychotics, analgesics including opioids, benzodiazepines and z-hypnotics in persistent AChEI users was studied in a follow-up period from four years before to two years after AChEI initiation in men and women of four age groups: 37–64, 65–72, 73–80 and 81–88 years.ResultsUse of antidepressants, antipsychotics and weaker analgesics increased in both sexes during the follow-up period in 11.764 persistent AChEI users. Women with pre-dementia and dementia stages of AD showed a prescription pattern with more use of psychotropics and opioids than men, except for antipsychotics.ConclusionFemale sex showed to have a significant influence on the prescriptions of psychotropics and analgesics in AD patients in a pre-dementia and dementia stage. The exception is for antipsychotics, that men used more than women. The prescription pattern showed a higher extent of polypharmacy of psychotropics and/or opioids in women than in men. The total prescription pattern of analgesics could indicate an undertreatment of pain in pre-dementia and dementia stages, most pronounced in men.

Pain, cognition and disability in advanced multiple sclerosis.

In patients with multiple sclerosis (MS), a relationship between physical disability and pain has been observed. In addition a relationship between physical disability and cognition in MS has been suggested. However, cognitive functions and pain appear not to be correlated in MS patients. Therefore, we examined whether a possible relationship between pain and cognitive functioning may exist, and if so, if such a relationship is mediated by physical disability. Forty-five MS patients with chronic pain, and in an advanced stage of the disease were included. Physical disabilities were assessed by the Expanded Disability Status Scale (EDSS). Episodic memory was assessed by means of the Eight Words test, and Face and Picture Recognition. Executive functions (EF) were examined by Digit Span Backward for working memory, and the Rule Shift Cards and Category Fluency test for cognitive flexibility. Pain Intensity and Pain Affect were assessed by means of visual analogue scales and one verbal pain scale and mood (depression, anxiety) by the Beck Depression Inventory and the Symptom Check List (SCL-90). The research questions were analyzed by means of regression analyses and the Sobel test for mediation. A significant relationship was found between Pain Affect and EF, but that relationship was not mediated by physical disabilities (EDSS). In addition, Pain Intensity and EF showed a significant relationship but only in combination with physical disabilities (EDSS). Finally, mood was related to pain affect. The findings suggest that the lower the EF, exclusively or in combination with more physical disabilities, the more the patient may suffer from pain. The more one is cognitively and physically impaired, the more one might suffer from pain, and, the less one is able to communicate pain. The latter could put MS patients at risk for underdiagnosing and undertreatment of pain.

Ethical Dilemma: Healthcare Surrogate Refusal of Opioid Administration

It is morally distressing when a healthcare provider sees patients with undertreated pain but is unable to provide adequate relief because of a surrogate's refusal of such treatment. This issue might occur when there is no clear advanced directive that represents patients’ wishes for treatment, and can be further complicated when patients are of minority cultural backgrounds. This article presents a case where the surrogate of a Korean–American woman with severe somatic pain from metastatic pancreatic cancer requested only acetaminophen be given to control the patient's pain. The ethical issues associated with surrogate misconceptions on therapeutic use of opioids are reviewed. This case highlights the ethical dilemma of withholding opioid treatment in a patient with advanced cancer. We conclude that the obligation to treat pain should be understood beyond the authority of surrogate refusal, in favor of patient quality of life, when an advance directive is not in place.

Low-dose ketamine as an adjuvant for pain control in a cancer patient: a case report

Cancer patients often suffer from pain related problems such as under-treatment of pain, ineffective and persistent opioid administration as well as adverse opioid use outcomes. There is a growing need for non-opioid analgesic alternatives for patients undergoing treatment for obstinate pain. Ketamine is a fast-acting N-methyl-D-aspartate (NMDA) receptor antagonist that has been emerging as an effective medication for pain alleviation. While protocols have been established for the use of Low-Dose Ketamine (LDK) for post-operative pain, there is growing evidence for using LDK as a clinical alternative to opioids in a palliative care setting. This case study involves monitoring the efficacy of LDK treatment in combination with opioid analgesics in a cancer patient in a hospital setting. This is a very selected case of a patient with Metastatic Prostate Cancer (Gleason 9 Adenocarcinoma) where LDK was shown to be efficacious at reducing pain when opioids and standard pain medications were not satisfactory. While the study involved using a relatively novel pharmacological protocol and close patient monitoring, the patient reported a sustained reduction in pain level based on the Numerical Rating Scale for months after the termination of LDK infusions. Moreover, the treatment also resulted in a reduction of total opioid usage after the addition of LDK. Although additional research is needed to ascertain optimal dosing schedules and route of Ketamine, given these promising findings, Ketamine may be a useful option for improving the treatment of refractory pain in patients with cancer and a good tool in palliative medicine for treating neoplastic pain.

Opioid Pseudoaddiction in a Patient with Long-Term Oxycodone Use for Chronic Pain

Pseudoaddiction is a term to describe drug-seeking behaviors in a patient that has inadequate pain control. It is the result of the medical undertreatment of pain, which poses iatrogenic harm to patients by withholding analgesic treatment [1]. The case presented is of a 26-year-old female with chronic back pain from a motor vehicle accident who was unable to find a physician to prescribe opioids after leaving the care of her primary care physician. She resulted to drug-seeking behaviors and alcohol use to relieve her severe pain.

The prevalence of pain in Huntington's disease in a large worldwide cohort

IntroductionPain could be an unknown non-motor symptom in Huntington's Disease (HD). The aim is therefore, to study the prevalence of pain interference, painful conditions and analgesic use across the different stages of HD and compare these levels to non-HD gene mutation carriers. MethodsA cross-sectional analysis of the Enroll-HD study was conducted in premanifest, manifest HD gene mutation carriers (n = 3989 and n = 7,485, respectively) and in non-HD gene mutation carriers (n = 3719). To investigate group differences, multivariable logistic regression analysis was performed with pairwise comparisons. ResultsIn the HD mutation carriers, the overall prevalence of pain interference was 34% (95% CI 31%–35%), of painful conditions 17% (95% CI 15%–19%) and analgesic use 13% (95% CI 11%–15%). Compared to non-mutation carriers, the prevalence of pain interference was significantly higher in the middle stage of HD (33% [95% CI 31%–35%] vs 42% [95% CI 39%–45%], P = 0,02), whereas the prevalence of painful conditions was significant lower in the late and middle stage of HD (17% [95% CI 16%–18%] vs 12% [95% CI 10%–14%], 15% [95% CI 13%–17%], P < 0,01]. No significant group difference was present in analgesic use. ConclusionsThe prevalence of pain interference increases as HD progresses, however, the prevalence of painful conditions and analgesics do not increase accordingly. Further studies are necessary to investigate the aetiology of pain in HD and the risk for undertreatment of pain.

Nurse-Administered Analgesic Treatment in Italian Emergency Medical Services: A Nationwide Survey.

BackgroundAcute pain is common among patients requiring assistance from prehospital emergency medical services (EMS). Nonetheless, the undertreatment of pain in this context remains a frequent phenomenon. Timely and effective analgesia is a crucial feature in emergency medicine. To ensure analgesia provision, prehospital paramedics and nurses can administer analgesics via standard operating protocols or under a physician’s remote supervision. Information about such protocols in Italian EMS is lacking.ObjectiveEvaluation of the availability of nurse’s standard analgesia protocols in Italy’s prehospital EMS settings.MethodsA cross-sectional online survey involved all 74 Italian emergency medical dispatch centres (EMDCs). Aside from descriptive statistics, we used χ2-analysis and Spearman-rank correlation to look for associations between geographical areas’ dependence upon independent variable categories and their correlations.ResultsOf all the 74 Italian EMDCs, 70 (94.6%) completed the survey, covering 100 provinces out of a total of 107 (93.5%). Operating nurses’ prehospital analgesia protocols are available in 46 provinces (46.0%). The availability of prehospital analgesia protocols is more extended in northern Italy EMDCs (n=30, 66.7%) than in central Italy (n=9, 42.8%) and southern Italy and islands (n=7, 20.6%). Morphine (76.1% for medical patients and 95.7% for trauma) and paracetamol (89.1% for both) are the most common drugs included in the prehospital analgesia protocols.ConclusionDespite international consensus on the necessity, efficacy, and safety of nurses’ prehospital analgesia provision, nurse-administered analgesia protocols are available in less than half of Italian provinces, with substantial differences between northern, central, and southern areas. These results indirectly indicate potential undertreatment of prehospital pain in Italy and yield practice improvements.

Racial, Ethnic, and Socioeconomic Discrepancies in Opioid Prescriptions Among Older Patients With Cancer.

Minority race and lower socioeconomic status are associated with lower rates of opioid prescription and undertreatment of pain in multiple noncancer healthcare settings. It is not known whether these differences in opioid prescribing exist among patients undergoing cancer treatment. This observational cohort study involved 33,872 opioid-naive patients of age > 65 years undergoing definitive cancer treatment. We compared rates of new opioid prescriptions by race or ethnicity and socioeconomic status controlling for differences in baseline patient, cancer, and treatment factors. To evaluate downstream impacts of opioid prescribing and pain management, we also compared rates of persistent opioid use and pain-related emergency department (ED) visits. Compared with non-Hispanic White patients, the covariate-adjusted odds of receiving an opioid prescription were 24.9% (95% CI, 16.0 to 33.9, P < .001) lower for non-Hispanic Blacks, 115.0% (84.7 to 150.3, P < .001) higher for Asian-Pacific Islanders, and not statistically different for Hispanics (-1.0 to 14.0, P = .06). There was no significant association between race or ethnicity and persistent opioid use or pain-related ED visits. Patients living in a high-poverty area had higher odds (53.9% [25.4 to 88.8, P < .001]) of developing persistent use and having a pain-related ED visit (39.4% [16.4 to 66.9, P < .001]). For older patients with cancer, rates of opioid prescriptions and pain-related outcomes significantly differed by race and area-level poverty. Non-Hispanic Black patients were associated with a significantly decreased likelihood of receiving an opioid prescription. Patients from high-poverty areas were more likely to develop persistent opioid use and have a pain-related ED visit.

Pain Management of Amazon Indigenous Peoples: A Community-Based Study.

PurposeIndigenous peoples are vulnerable populations that live in remote areas of the Amazon forest with limited access to health-care services. Underreporting and undertreatment of pain is a common event in the general population but little is known about these issues in indigenous peoples. The aim of this study was to investigate the characteristics and cultural aspects of pain management in five ethnicities of the Brazilian Amazon.Materials and MethodsCross-sectional study carried out with adult indigenous individuals from five ethnicities of the Brazilian Amazon over two scientific expeditions (June–July/2017 and February–March/2019). Pain assessment included etiology, intensity, duration, aggravating and alleviating factors, body location, impact of pain on activities of daily living, and treatment.ResultsNinety indigenous individuals with a mean age of 41.42 ± 19.59 years (range 19‒98 years) and median age of 37 years participated in the study. Sixty-four individuals (71.1%) reported experiencing pain at the time of interview with intermittent musculoskeletal pain of strong intensity being the more prevalent (back pain: 45.3%, joint pain: 43.7%) followed by headache (26.5%). The main alleviating factors reported were traditional indigenous medicine (21.0%) and rest (30.0%), and physical exertion was the main aggravating factor (69.0%). Most study participants reported that pain affected their mood, activities of daily living, and sleep and that they used both traditional indigenous medicine (78.0%) and conventional medicine (81.0%) for pain relief.ConclusionMusculoskeletal pain is prevalent among indigenous individuals, affects their quality of life, and is partly attributed to their lifestyle. Cultural aspects mediating the pain experience were observed. Traditional indigenous medicine for pain relief remains partially preserved among the ethnic groups investigated. The findings of this study can help improve the delivery care to these vulnerable populations.

A protocol to develop a standard guideline for neonatal pain management.

BackgroundHospitalized newborns experience a high frequency of painful procedures. Undertreated pain has a series of adverse physical and psychosocial effects on newborns. Guidelines successfully applied in clinical practice can effectively improve pain management in NICUs and reduce the incidence of pain. Neonatal care providers in China are in urgent need of a high-quality, evidence-based guideline for the treatment and management of neonatal pain. The National Clinical Research Center for Child Health and Disorders is leading the development of a standard guideline for neonatal pain management suitable for the medical environment in China providing empirical support and safety guarantees for clinical practice. The WHO Collaborating Centre for Guideline Implementation and Knowledge Translation will provide technical support and guidance. The purpose of this paper is to outline the detailed methodology and technical route of guideline development.MethodsWe will follow the WHO principles and methods for the formulation of standard guidelines. The critical steps for developing the guideline are as follows: (I) definition of the guideline Scope; (II) establishment of guideline working groups; (III) selection of the clinical questions; (IV) performance of systematic reviews; (V) grading the quality of the body of evidence; and (VI) formulating recommendations and reaching consensus.DiscussionThis protocol would ensure that the process of guideline development is normative, scientific, and transparent. The standard guideline for neonatal pain management based on the available high-quality evidence and tailored to the Chinese health care system will help neonatal caregivers in NICUs effectively manage neonatal pain.Guideline registrationThe guideline was registered at the International Practice Guidelines Registry Platform. The registration No. is IPGRP-2021CN044.

A Bibliometric Analysis of Published Literature in Postoperative Pain in Elderly Patients in Low- and Middle-Income Countries.

Postoperative pain (POP) remains a major challenge for surgeons and anesthesiologists worldwide, especially in low- and middle-income countries. Elderly patients are at higher risk for undertreatment of pain. Despite that, there is a paucity of papers addressing POP among this population in developing countries. This study aimed to provide a bibliometric analysis of the literature concerning postoperative pain in elderly patients from low- and middle-income countries. It was performed an extensive search of papers on this subject through the Web of Science and Scopus database using a series of uniterms and, including publications from 2001 to 2021. Publication quality was assessed by using total citation frequency, average citations per item and other citation indexes. Citation indexes were low, with the highest reaching 15 citations. In conclusion, few studies of postoperative pain in the elderly in countries with medium and low income, indicating a need that has not yet been met for this population and in these areas of the world. The published studies were not specifically aimed at the elderly, had limited impact, low international visibility. They were not epidemiological studies and are not robust, weakening knowledge and decision-making towards policies directed at this vulnerable population.

The experience of pain among cancer patients at the University of the Philippines: Philippine General Hospital Cancer Institute—A cross-sectional study.

e24078 Background: Pain is one of the most common and dreaded sequelae of cancer, occurring in approximately 55% of patients. The experience of pain takes a toll on the patients’ quality of life. However, many patients do not receive adequate pain management. This study aimed to determine the prevalence of pain, its severity, and the adequacy of pain management among cancer patients in the Philippines. Methods: A cross-sectional study was conducted at a representative cancer center in the Philippines, enrolling 351 cancer patients. Pain severity was assessed using the Brief Pain Inventory-Short Form (BPI-SF) Filipino. The BPI evaluates pain severity and its impact on daily functioning (pain interference). To ascertain the adequacy of pain control, the pain management index (PMI) was calculated by subtracting the subtracting the severity of pain reported by the patient from the type of analgesic treatment received. Logistic regression analysis was conducted to evaluate the factors associated with worst pain and adequacy of pain management. Data were analyzed using Stata version 16.0, with statistical significance set at p &lt; 0.05. Results: Three hundred three cancer patients (86.3%) experienced pain. Approximately 3 out of 5 patients (n = 208) did not receive adequate pain control, and one-third of patients experienced severe pain (n = 121). Patients who reported severe pain interference (n = 110) had three times greater odds to experience severe pain (OR 3.2, 95% CI 1.82-5.61, p &lt; 0.001). Those patients who had regular follow up were 65% less likely to experience severe pain (OR 0.35, 95% CI 0.16 – 0.78, p = 0.01). Patients who used pain medications (n = 196) were 14 times more likely to experience adequate pain management (OR 14.19, 95% CI 6.53 – 30.83, p &lt; 0.001). Patients who were referred to pain service (n = 25) were seven times more likely to report adequate pain control (OR 6.62, 95% CI 2.50 – 17.56, p &lt; 0.001). Conversely, those patients who reported a severe rating on total pain interference were 75% less likely to experience adequate pain management (OR 0.25, 95% CI 0.17 – 0.35, p &lt; 0.001). Conclusions: Unexpectedly, there was a high prevalence of pain among cancer patients at a representative cancer center in the Philippines. Pain exerts a heavy toll on patients, affecting daily functioning. The undertreatment of pain discovered in this study (59% of cancer patients) is alarming. Timely pain evaluation can help identify the presence of pain and the need for appropriate use of analgesics. The assessment and management of pain is a critical component of cancer care that should not be neglected.

Effect of Wound Infiltration with Bupivacaine after Laparoscopic Cholecystectomy – A Randomized, Controlled Trial

Background and Objective: Adequate post-operative pain management can improve surgical outcome. Patients undergoing surgery can be affected socially, psychologically, economically with undertreated pain. We aimed to evaluate the effect of 0.25% bupivacaine infiltration on postoperative pain, analgesic requirement, satisfaction level, hospital discharge and quality of life after laparoscopic cholecystectomy.&#x0D; Methodology: Fifty eight patients undergoing laparoscopic cholecystectomy were enrolled and randomized in two groups – placebo and intervention. Patients were infiltrated with 10 ml 0.25% bupivacaine in intervention and 10 ml 0.9% normal saline in placebo group. Post-operative pain was managed with morphine using Patient Controlled Analgesia (PCA). Pain intensity was assessed on the matrix of visual analogue scale and verbal rating scale up to 12 post-operative hours. This study also assessed its effect on analgesic requirements, hospital stay, patient satisfaction level after 24hours, pain score on discharge, time taken to return to job and quality of life (on 15th and 30th post-operative day).&#x0D; Results: It was revealed 0.25% bupivacaine can lower post-operative pain up to six post-operative hour of performing laparoscopic cholecystectomy. Total analgesic requirement was also reduced (p= 0.0003) with decreased side effect like vomiting (p= 0.0002). However, satisfaction and quality of life were not affected by bupivacaine infiltration in this study.&#x0D; Conclusion: 0.25% Bupivacaine infiltration offered more effective management of postoperative analgesia with decreased analgesic requirement and less incident of vomiting. But it was not effective after long duration in terms of satisfaction level, hospital discharge, time to return to job or quality of life.

Undertreated or untreated chronic pain in children can be especially burdensome to families by disrupting routines, restricting the child's daily activities, and increasing risk of long-term disability (Paediatr Drugs 2002;4:737-46). Therefore, it is not unusual for chronic pain to be highly comorbid with psychiatric disorders. This association is mediated by significant overlap in biological pathways. First, central and peripheral noradrenergic (NA) and serotoninergic (5-HT) pathways are affected in both pain and mood disorders (Prog Neuropsychopharmacol Biol Psychiatry 2018;87B:290-7; J Psychiatry Neurosci 2001;26:21-9). A pathway involving serotonergic neurons in the dorsal raphe nucleus has been implicated in chronic pain as well as depression (Nat Neurosci 2019;22:1612-4).

Pain Management in Painful Psoriasis and Psoriatic Arthropathy: Challenging and Intricately Intertwined Issues Involving Several Systems.

Psoriasis and psoriatic arthropathy are inflammatory autoimmune conditions that can lead to profound emotional distress, social stigmatization, isolation, disfigurement, pain, disability, unemployment, and decreased quality of life. Thus, this disease has immense psychological, social, and economic implications as the pain experienced is closely associated with the primary disease burden. This review focuses on discussing the primary disease burden of psoriasis and psoriatic arthropathy, as well as management of different types of pain in these patients. Pain affects over 40% of patients with psoriasis, ranging from neuropathic to nociceptive. Treatment of pain largely focuses on treating the underlying disease with mild topical steroids and non-steroidal medications including vitamin D analogs followed by systemic immunomodulatory agents for more severe disease. Interventional options such as corticosteroid injections are available for select cases (conditional recommendation). Psoriasis and psoriatic arthropathy have been associated with underreporting and resultant undertreatment of pain. Pain control in these conditions is complex and requires a multidisciplinary approach. More research and guidelines are needed in the areas of reporting of psoriatic disease, associated pain, psoriatic nociception, and optimal clinical management.

Sex, Race, Insurance, and Pain: Do Patient Sociodemographics Influence Postoperative Opioid Prescriptions Among Hand Surgeons?

Social and demographic factors may influence patient treatment by physicians. This study analyzes the influence of patient sociodemographics on prescription practices among hand surgeons. We performed a retrospective analysis of all hand surgeries (N = 5278) at a single academic medical center from January 2016 to September 2018. The average morphine milligram equivalent (MME) prescribed following each surgery was calculated and then classified by age, race, sex, type of insurance, and history of substance use or chronic pain. Multivariate linear regression was used to compare MME among groups. Overall, patients with a history of substance abuse were prescribed 31.2 MME more than those without (P < .0001), and patients with a history of chronic pain were prescribed 36.7 MME more than those without (P < .0001). After adjusting for these variables and the type of procedure performed, women were prescribed 11.2 MME less than men (P = .0048), and Hispanics were prescribed 16.6 MME more than whites (P = .0091) overall. Both Hispanic and black patients were also prescribed more than whites following carpal tunnel release (+19.0 and + 20.0 MME, respectively; P < .001). Patients with private insurance were prescribed 24.5 MME more than those with Medicare (P < .0001), but 25.0 MME less than those with Medicaid (P < .0001). There were no differences across age groups. Numerous sociodemographic factors influenced postoperative opioid prescription among hand surgeons at our institution. These findings highlight the importance of establishing more uniform, evidence-based guidelines for postoperative pain management, which may help minimize subjectivity and prevent the overtreatment or undertreatment of pain in certain patient populations.

Gender Biases in Estimation of Others’ Pain

Caregiving and other interpersonal interactions often require accurate perception of others’ pain from nonverbal cues, but perceivers may be subject to systematic biases based on gender, race, and other contextual factors. Such biases could contribute to systematic under-recognition and undertreatment of pain. In 2 experiments, we studied the impact of perceived patient sex on lay perceivers’ pain estimates and treatment recommendations. In Experiment 1 (N = 50), perceivers viewed facial video clips of female and male patients in chronic shoulder pain and estimated patients’ pain intensity. Multi-level linear modeling revealed that perceivers under-estimated female patients’ pain compared with male patients, after controlling for patients’ self-reported pain and pain facial expressiveness. Experiment 2 (N = 200) replicated these findings, and additionally found that 1) perceivers’ pain-related gender stereotypes, specifically beliefs about typical women's vs. men's willingness to express pain, predicted pain estimation biases; and 2) perceivers judged female patients as relatively more likely to benefit from psychotherapy, whereas male patients were judged to benefit more from pain medicine. In both experiments, the gender bias effect size was on average 2.45 points on a 0–100 pain scale. Gender biases in pain estimation may be an obstacle to effective pain care, and experimental approaches to characterizing biases, such as the one we tested here, could inform the development of interventions to reduce such biases.Perspective: This study identifies a bias towards underestimation of pain in female patients, which is related to gender stereotypes. The findings suggest caregivers’ or even clinicians’ pain stereotypes are a potential target for intervention.

Racial and Ethnic Disparities in Pain Management

Pain is subjective, which makes its management a complicated task. The challenge of medical decision-making associated with pain often requires health care providers to rely heavily on their individual discretion and experience. This often creates an avenue for biases to play a role in the selection of the best available and most appropriate pain management interventions. Therefore, the overall purpose of this review is to summarize the current literature related to racial and ethnic disparities in pain management. Electronic searches of four databases revealed 2,112 articles; however, only six studies met criteria for inclusion in this review. Even when the source of pain is the same, research indicates management may differ between racial or ethnic groups. While the treatment of objectively painful conditions remains relatively constant among races and ethnicities, inequities in pain management become more apparent in the treatment of conditions characterized by only subjective pain indicators. Further disparities were identified in the dosage, dosage reduction, and oversight of opioid analgesics between groups. Inequities in prescribing patterns widen existing healthcare disparities by contributing to undertreatment of pain in ethnic minorities and overtreatment of pain and subsequent risk of opioid abuse in Whites. Health care providers must use a patient-centered and evidence-based approach to combat the ambiguity of clinical decision-making regarding pain. When knowledgeable of appropriate standard of care for pain management, athletic trainers can identify when a patient’s pain needs are unmet or when substance abuse interventions may be necessary.

Cut-off points between pain intensities of the postoperative pain using receiver operating characteristic (ROC) curves

BackgroundPain assessment and management are important in postoperative circumstances as overdosing of opioids can induce respiratory depression and critical consequences. We aimed this study to check the reliability of commonly used pain scales in a postoperative setting among Korean adults. We also intended to determine cut-off points of pain scores between mild and moderate pain and between moderate and severe pain by which can help to decide to use pain medication.MethodsA total of 180 adult patients undergoing elective non-cardiac surgery were included. Postoperative pain intensity was rated with a visual analog scale (VAS), numeric rating scale (NRS), faces pain scale revised (FPS-R), and verbal rating scale (VRS). The VRS rated pain according to four grades: none, mild, moderate, and severe. Pain assessments were performed twice: when the patients were alert enough to communicate after arrival at the postoperative care unit (PACU) and 30 min after arrival at the PACU. The levels of agreement among the scores were evaluated using intraclass correlation coefficients (ICCs). The cut-off points were determined by receiver operating characteristic curves.ResultsThe ICCs among the VAS, NRS, and FPS-R were consistently high (0.839–0.945). The pain categories were as follow: mild ≦ 5.3 / moderate 5.4 ~ 7.1 /severe ≧ 7.2 in VAS, mild ≦ 5 / moderate 6 ~ 7 / severe ≧ 8 in NRS, mild ≦ 4 / moderate 6 / severe 8 and 10 in FPS-R. The cut-off points for analgesics request were VAS ≧ 5.5, NRS ≧ 6, FPS-R ≧ 6, and VRS ≧ 2 (moderate or severe pain).ConclusionsDuring the immediate postoperative period, VAS, NRS, and FPS-R were well correlated. The boundary between mild and moderate pain was around five on 10-point scales, and it corresponded to the cut-off point of analgesic request. Healthcare providers should consider VRS and other patient-specific signs to avoid undertreatment of pain or overdosing of pain medication.
