Does In-Hospital Opioid Use Affect Opioid Consumption After Total Joint Arthroplasty?

BACKGROUND: Preoperative opioid use strongly correlates with greater postoperative opioid use and complications following total joint arthroplasty (TJA). However, there is a lack of information regarding the effect of opioid consumption during the hospital stay and within the operating room on postoperative opioid use. METHODS: We retrospectively reviewed 369 consecutive patients undergoing primary TJA at an academic center over a 9-month period. Ninety-day preoperative and postoperative opioid prescriptions were obtained from the state's drug monitoring database. In-hospital opioid consumption data was obtained from the preoperative unit, operating room, postanesthesia care unit (PACU), and hospital floor. Multivariate analysis was utilized to compare patients' total in-hospital opioid consumption with their preoperative and postoperative use, along with opioid use throughout the hospitalization. RESULTS: Total in-hospital opioid consumption was independently associated with postoperative opioid use (rs = 0.17, P = .0010). Opioids consumed on the hospital floor correlated with opioid use in the preoperative unit (rs = 0.11, P = .0338) and PACU (rs = 0.15, P = .0032). Increased preoperative opioid consumption was the greatest risk factor for excessive postoperative use (rs = 0.44, P < .0001). A greater proportion of patients <65 years of age were high posthospital opioid consumers (P = .0146) and significantly more TKA patients were in the higher use groups (P = .0006). CONCLUSION: In-hospital opioid use is independently associated with preoperative and postoperative consumption. Preoperative opioid use remains the greatest risk factor for increased opioid consumption after TJA. Multimodal approaches to decrease reliance on opioids for pain control during hospitalization may offer hope to further decrease postoperative usage. LEVEL OF EVIDENCE: III.

Prevalence of Chronic Opioid Use in the Elderly After Hip Fracture Surgery.

BACKGROUND: While interest has focused on opioid use after total hip arthroplasty, little research has investigated opioid use in elderly patients after hip fracture. We hypothesize that a substantial number of opioid-naïve elderly patients go on to chronic opioid use after hip fracture surgery. METHODS: We reviewed a consecutive series of 219 patients 65 years and older who underwent surgical fixation between January 1, 2016 and February 28, 2019 for a native hip fracture. Patients were excluded for polytrauma, periprosthetic or pathologic fractures, recent major surgery, or death within 90 days of their hip surgery. The state prescription monitoring database was used to determine opioid use. RESULTS: Overall, 58 patients (26%) were postoperative chronic opioid users. Of the initial 188 opioid-naïve patients, 43 (23%) became chronic users. Of the 31 preoperative opioid users, 15 (48%) continued as chronic users. Chronic postoperative users were more likely to be White (76% vs 91%, P = .04), younger (78 vs 82 years, P = .003), and preoperative opioid users (odds ratio 3.3, P = .007). Arthroplasty vs fixation did not affect the rate of chronic opioid use (P = .22). CONCLUSION: Chronic opioid use is surprisingly common after hip fracture repair in the elderly. Twenty-three percent of opioid-naïve hip fracture patients became chronic users after surgery. Continued vigilance is needed by orthopedic surgeons to limit the amount and duration of postoperative narcotic prescriptions and to monitor for continued use.

Factors Predicting Chronic Opioid Use after Orthopedic Surgical Procedures.

BACKGROUND: Opioid abuse has been an increasing problem since the 1990s. With over 47,000 opioid related deaths recorded in 2017 alone, concerns have been raised regarding the dangers of introducing opioids perioperatively to patients undergoing major surgeries. OBJECTIVES: The present study proposes to examine the frequency, amount, and trends in post-operative opioid consumption in patients undergoing orthopedic surgical procedures. STUDY DESIGN: This was a randomized, retrospective questionnaire-based study. SETTING: Patients who underwent any type of orthopedic surgery at the University of Pennsylvania Presbyterian Hospital from 1/1/2018 to 3/12/2019 were randomly selected and called during the summer of 2019. METHODS: In this retrospective questionnaire-based study, 828 patients were called by telephone in the summer of 2019. These patients were asked a variety of questions involving opioid consumption behavior post-surgery. The study ended after receiving responses from 200 patients. RESULTS: Nineteen (9.5%) patients reported positively for experiencing euphoria while taking opioids post-surgery. Of the 200 patients contacted, 6 patients (3%) reported switching to marijuana instead of opioids. Thirty-eight (19%) patients preferred to take no opioids at all post-surgery, and one patient was found to have given their prescription to a family member or friend. Twenty-one patients (10.5%) were found to have been taking opioids for non-severe pain. Blacks and whites were the most common racial demographics, making up 84 and 109 of the totals, respectively. The odds ratios for all of the predictors showed that the relative risk for opioid misuse was higher for black patients than white patients (OR = 3.034). There was no relationship between the intra- and post-operative opioid administration and long-term opioid misuse. LIMITATIONS: Patients are self-selected and had the option to opt out of the study when contacted. Some patients may not have been available to answer the phone when our study was being conducted. This study was only conducted for orthopedic patients and for patients who received surgery at the University of Pennsylvania Presbyterian Hospital, thus affecting the demographics for our research. CONCLUSIONS: Prescription opioid misuse is more common among the black population. The total opioid consumption is frequently lower than the quantity prescribed. Patients frequently use opioids even though they feel that pain is insufficient to deserve such an intervention. Euphoria is experienced by a significant number of patients taking prescription opioids Often patients do not take any opioids, although they had prescriptions.

Diagnosis of Opioid Use Disorder by Youths Assessed in Acute Care Settings in British Columbia, Canada.

OBJECTIVES: To describe trends in the number of youths diagnosed with opioid use disorder (OUD) and to identify factors associated with OUD diagnosis in acute care settings. STUDY DESIGN: Data from a population-based retrospective cohort study with linkage of 6 health administrative databases for 13 009 youth age 12-24 years identified with OUD between 2001 and 2018 in British Columbia, Canada were used to describe annual diagnoses. Using a multiple logistic regression model, we estimated the association between past-year health care utilization and OUD diagnosis in acute settings, controlling for sociodemographic and OUD-related comorbid conditions. RESULTS: Annual OUD diagnoses quadrupled between 2003 and 2017 (from 326 to 1473). Among the 6579 youth diagnosed with OUD between April 1, 2013 and September 30, 2018, 88.1% had past-year health system contacts. Youth age 12-18 had higher odds of OUD diagnosis in acute care (aOR 2.04; 95% CI 1.78, 2.34). Compared with no health care contact, youth receiving outpatient care only were less likely to be diagnosed with OUD in acute care (aOR 0.69; 95% CI 0.56, 0.84) and those with >1 urgent hospitalization were more likely to be diagnosed with OUD in acute care (aOR 1.87; 95% CI 1.40,2.49). CONCLUSIONS: More than 88% of youth had past-year health system contacts prior to diagnosis. Those age 12-18 years and with urgent hospitalizations in the year prior to diagnosis were more likely to have OUD diagnosed in acute care settings. Establishing an effective evidence-based system for early detection and intervention among youth with OUD must be a priority.

Forecasting Opioid Use Disorder at 25 Years of Age in 16-Year-Old Adolescents.

OBJECTIVE: To evaluate the accuracy of detecting 16-year-old male (n = 465) and female (n = 162) youths who subsequently manifest opioid use disorder (OUD) at 25 years of age. We hypothesized that the combined measures of 2 components of etiology, heritable risk, and substance use, accurately detect youths who develop OUD. STUDY DESIGN: Heritable risk was measured by the transmissible liability index (TLI). Severity of the prodrome presaging OUD was quantified by the revised Drug Use Screening Inventory containing the consumption frequency index (CFI) documenting substance use events during the past month and the overall problem density (OPD) score indicating co-occurring biopsychosocial problems. Diagnosis of OUD was formulated by a clinical committee based on results of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition in conjunction with medical and social history records. RESULTS: Bivariate analysis shows that the TLI, CFI, and OPD scores at 16 years of age predict OUD at 25 years. Multivariate modeling indicates that the TLI combined with the CFI predict OUD with 86% accuracy (sensitivity = 87%; specificity = 62%). The TLI and CFI at 16 years of age mediate the association between parental substance use disorder and OUD in offspring at 25 years of age, indicating that these measures respectively evaluate risk and prodrome. CONCLUSIONS: These results demonstrate the feasibility of identifying youths requiring intervention to prevent OUD.

Understanding Opioid Use After Total Hip Arthroplasty: A Comprehensive Analysis of a Mandatory Prescription Drug Monitoring Program.

INTRODUCTION: Opioids remain the most prescribed medication after total hip arthroplasty (THA) despite the potential for abuse and adverse effects. Given the high rates of opioid abuse and potential adverse effects, the reporting of controlled substances is now mandatory in many statewide databases. This study aimed to use a mandatory statewide database to analyze opioid prescription patterns in postoperative THA patients and identify independent risk factors for those patients who need a second prescription and/or require prolonged use (>6 months). METHODS: We retrospectively reviewed a consecutive series of 619 primary THAs. Demographic and comorbidity information were collected for all patients. Narcotic prescription data (converted to morphine milligram equivalents) as well as prescription data for sedatives, benzodiazepines, and stimulants were collected from the State's Controlled Substance Monitoring websites 6 months before and 9 months after the index procedure. Bivariate and multivariate analyses were done for second prescription and continued use. RESULTS: Of the 619 patients who underwent THA, 34.9% (216/619) used preoperative opioids, 36.2% (224/619) filled a second opioid prescription, and 10.5% (65/619) had continued use past 6 months. Patients with preoperative opioids were at an approximately 4-fold increased odds of requiring a second script and 12 times odds of continued opioid use. In the multivariate analysis, independent risk factors for requiring a second prescription, in descending order of magnitude, included the use of any sedative or sleep aid prescription and preoperative narcotic use. Independent risk factors for continued narcotic use longer than 6 months after THA included preoperative narcotic use and increased length of stay. DISCUSSION: Several risk factors and their relative weight have been identified for continued narcotic consumption after THA. It is important for surgeons to consider these predisposing factors preoperatively during the informed consent process and for managing postoperative pain expectations.

Cross-cultural adaptation of the Pain Medication Questionnaire for use in Brazil.

BACKGROUND: The Pain Medication Questionnaire (PMQ) assesses the risk of opioid abuse in people with non-oncological chronic pain. METHODS: This is a methodological study conducted at a hemotherapy centre in Recife, Pernambuco state, Brazil. A Cross-cultural adaptation was carried out by a committee of nine specialists, and we applied the PMQ to a pre-final sample of 40 individuals with sickle cell anemia, in addition to a sociodemographic and clinical questionnaire. RESULTS: The mean agreement indexes for PMQ equivalences were the following: semantic (0.996), idiomatic (0.970), experiential (0.991), conceptual (0.953), language clarity (0.991), practical relevance (0.906), and theoretical relevance (0.945). Assessment of the PMQ showed that 50% of participants obtained a score equivalent to medium risk of opioid abuse. Cronbach's alpha coefficient for the adapted PMQ instrument was 0.705, ranging from 0.641 to 0.736 among its items. CONCLUSION: The cross-cultural adaptation of the Pain Medication Questionnaire was satisfactory and easy to apply in the Brazilian population. It is clinically relevant, contributing professional practice and enlightening patients with sickle cell anemia on their behavioral dynamics with respect to opioid consumption. It will also contribute to teaching and research, because it is a useful tool for investigating the risk of abusive behavior in people with chronic pain.

A Cohort Comparison of Buprenorphine versus Methadone Treatment for Neonatal Abstinence Syndrome.

OBJECTIVES: To compare the duration of opioid treatment and length of stay among infants treated for neonatal abstinence syndrome (NAS) by using a pilot buprenorphine vs conventional methadone treatment protocol. STUDY DESIGN: This retrospective cohort analysis evaluated infants who received pharmacotherapy for NAS at 6 hospitals in Southwest Ohio from January 2012 through August 2014. A single neonatology provider group used a standardized methadone protocol across all 6 hospitals. However, at one of the sites, infants were managed with a buprenorphine protocol unless they had experienced chronic in utero exposure to methadone. Linear mixed models were used to calculate adjusted mean duration of opioid treatment and length of inpatient hospitalization with 95% CIs in infants treated with oral methadone compared with sublingual buprenorphine. The use of adjunct therapy was examined as a secondary outcome. RESULTS: A total of 201 infants with NAS were treated with either buprenorphine (n = 38) or methadone (n = 163) after intrauterine exposure to short-acting opioids or buprenorphine. Buprenorphine therapy was associated with a shorter course of opioid treatment of 9.4 (CI 7.1-11.7) vs 14.0 (12.6-15.4) days (P < .001) and decreased hospital stay of 16.3 (13.7-18.9) vs 20.7 (19.1-22.2) days (P < .001) compared with methadone therapy. No difference was detected in the use of adjunct therapy (23.7% vs 25.8%, P = .79) between treatment groups. CONCLUSION: The choice of pharmacotherapeutic agent is an important determinant of hospital outcomes in infants with NAS. Sublingual buprenorphine may be superior to methadone for management of NAS in infants with select intrauterine opioid exposures.

Patient Perspectives of Acute Pain Management in the Era of the Opioid Epidemic.

STUDY OBJECTIVE: To inform the development of interventions that could improve patient engagement around the risks and benefits of alternative approaches to pain management in the emergency department (ED), we seek to capture the perspectives and experiences of patients treated for pain in this setting. METHODS: Three trained interviewers conducted semistructured open-ended telephone interviews with patients discharged from a single urban academic ED after presenting with acute pain related to fracture, renal colic, or musculoskeletal back injury. We recruited subjects until achieving thematic saturation according to periodic review of the interview transcripts. Interviews were audio recorded, professionally transcribed, and uploaded into QSR NVivo (version 10.0) for coding and analysis using modified grounded theory. An interdisciplinary team double coded the data and convened to review emerging themes, ensure interrater reliability, and establish consensus on discrepancies. RESULTS: We had 23 completed subject interviews, the majority of which were women. Interrater reliability for coding exceeded 90%. The major themes elicited centered on domains of patient awareness of the potential for opioid dependence and patient-provider communication relating to pain management. From the patient perspective, emergency physicians typically do not present alternative pain management options or discuss the risks of opioid dependence. Patients with negative experiences related to pain management describe deficiencies in patient-provider communication leading to misunderstanding of clinical diagnoses, fragmentation of care among their health care providers, and a desire to be involved in the decisionmaking process around their pain management. Patients with positive experiences commented on regular communication with their care team, rapid pain management, and the empathetic nature of their care providers. Patients communicate fears about the risks of opioid addiction, beliefs that following a prescribed opioid regimen is protective of developing opioid dependence, and an understanding of the broader tensions that providers face relating to the prescription of opioid therapy. CONCLUSION: Patients identified a deficit of communication around opioid risk and pain management options in the ED.

Clinical and pathologic characteristics of intranasal abuse of combined opioid-acetaminophen medications.

BACKGROUND: The nonmedical abuse of prescription opioids via intranasal administration is a growing problem. The objective of this study is to investigate of the typical presentation of intranasal opioid-acetaminophen abuse and outline optimal therapy. METHODS: This study was a retrospective chart review. Patients with intranasal pathology from inhalation of combined opioid-acetaminophen medications (COAMs) from 3 academic otolaryngology practices in western Pennsylvania from January 2012 to October 2012 were included in the review. RESULTS: Seven adults ranging in age from 23 to 46 years were identified with nasal complaints from the intranasal inhalation of COAMs. All patients presented with nasal pain and were found to have fibrinous necrotic nasal mucosa involving the posterior nasal cavity and nasopharynx. Of the 7 patients, 6 (85.7%) presented with a septal perforation. Pathology and culture revealed fungus in 85.7% of the patients; however, no invasive fungal disease was noted in any of the specimens. Patients did not improve with either systemic or topical antifungal therapy. Polarizable material characteristic of talc used as a tablet binder was present in the histopathology of 4 of 7 (57.1%) patients. Patients who abstained from intranasal drug use along with serial debridement demonstrated the greatest improvement. CONCLUSION: Intranasal COAM abuse causes nasal pain, tissue necrosis with potential septal and palatal perforation, and noninvasive fungal colonization. Antifungal therapy was of no benefit in the current series of patients. Current therapy should focus on recognition of the etiology of patients' pathology and encourage abstinence from intranasal use of these drugs along with serial debridements.

Long-term neuropsychological effects of opioid use in children: a descriptive literature review.

BACKGROUND: Use of opioids in the management of pain and its consequences in children presents a substantial challenge. A significant concern in pediatric pain management is the long-term neuropsychological consequences of opioids. OBJECTIVES: The authors aim to provide a descriptive review of the current literature surrounding the neuropsychological impact of opioid use in children, along with possible extrapolations from their use in adults and animal models. STUDY DESIGN: Systematic review of published literature. SETTING: Various universities in the United States. METHODS: The electronic review for papers published between January 1992 and December 2012 was conducted using Medline/Pubmed, PsychInfo, CINAHL, the Cochrane Library database, and Google Scholar. RESULTS: Findings assessing pediatric pain patients treated with opioids demonstrated no significant differences in intelligence, behavior, vocabulary, or motor skills. One study reported a decrease in a visuo-constructional ability, which measured higher order executive function. Studies from prenatal illicit opioid exposure found poorer performance on measures of language, verbal ability, mathematics, reading, impulse control, and school readiness skills. The literature from adult prescribed opioid users has mixed results. Some showed impairment in the neuropsychological domains of memory, decision-making, attention, concentration, information processing, psychomotor speed, visual special skills, and hand-eye coordination, while others found no differences or revealed improved perceptual-cognitive status, possibly due to the removal of pain as a stressor. LIMITATIONS: Very few studies looked into the long term neuropsychological and cognitive effects of the opioids in pediatric population. In an attempt to extrapolate from other groups, this review also included literature from adult patients, prenatal opioid exposure, and animal studies. CONCLUSION: Opioid medications have the potential to produce long-lasting neuropsychological side effects. However, given the negative consequences of untreated pain, the potential benefit may offset their risk. More studies are needed to clarify this complex interaction.

What do patients do with unused opioid medications?

OBJECTIVES: The volume of opioid medications being prescribed in the United States is increasing rapidly. Problems associated with the misuse of opioid medications are also increasing, in part because of medication diversion from legitimate prescriptions. However, little is known about what patients do with any unused opioid medications. This paper uses a qualitative analysis of patients' self-report of medication storage and retention habits to begin to address this gap. METHODS: We analyzed responses to the Prescription Drug Use Questionnaire in conjunction with other data on prescription opioid use in a sample of 191 Veteran patients (83% of whom had a preexisting factor associated with higher rates of opioid misuse) who received one or more opioid prescriptions in the previous 12 months. RESULTS: Only 6.3% of participants disposed of extra medications and 24.1% reported having no extra opioids. A total of 65.4% of participants reported retaining some or all opioids even if they ceased taking the medication, and some participants accumulated large amounts of medication. A total of 34.0% of participants described engaging in sharing or diversion of opioids at least once, most often receiving them from a family member or a friend. DISCUSSION: A majority of patients retain unused opioids, and medication sharing is common. Interventions to improve monitoring of patient experience with opioid medication, educate patients about the dangers of opioid use by nonprescribed others, and increase information about medication disposal options could decrease the supply of opioid medications available for misuse.

Toxicologia e profissionais de saúde: uso abusivo e dependência / Toxicology and health professionals: drug abuse and dependence

Na década de 1990, foi demonstrada alta prevalência no uso abusivo de opioides pelos anestesiologistas. Desde então, houve aumento nas pesquisas desse tipo de comportamento entre os profissionais da área de saúde. No entanto, observa-se aumento da prevalência da dependência de drogas entre esses profissionais, devido a várias situações como: estresse, extensas jornadas de trabalho e o fácil acesso aos medicamentos. Outros fatores envolvidos estão relacionados a aspectos bioquímicos, genéticos e psiquiátricos. Objetivo: discutir a real prevalência, a etiologia e as estratégias de controle no abuso de propofol, opioides e cetamina entre os profissionais da saúde, especialmente entre as especialidades médicas. Métodos: revisão de artigos científicos disponíveis nos bancos de dados do Pubmed e Scielo. Resultados: entre os profissionais de saúde, a prevalência da dependência química de propofol, opioides (principalmente fentanil e sufentanil) e cetamina é mais alta entre os anestesiologistas, médicos socorristas e psiquiatras. Foi encontrada considerável associação entre a dependência química desses profissionais e outras psicopatogenias, como transtornos de personalidade e depressão. Esses transtornos podem até mesmo influenciar a escolha da droga utilizada. Conclusão: apesar do aumento do número de dependentes químicos em propofol, opioides e cetamina entre os profissionais da saúde, existem poucas estratégias de controle para impedir o acesso a esses medicamentos para uso próprio. Além disso, há poucas informações sobre a segurança do profissional em relação ao retorno ao ambiente de trabalho após o período de reabilitação.

A high prevalence of opioid abuse was found among anesthesiologists in the 1990s. Ever since, an increased number of studies have focused on health professionals? behaviors. However, the prevalence of drug abuse has increased among these professionals as a result of: stress, long work hours, and easy access to the drugs. Other factors involved are of biochemical, genetic and psychiatric nature. Objective: To discuss the actual prevalence, etiology and control strategies related to propofol, opioid and ketamine abuse among health professionals, particularly specialist physicians. Methods: Review of academic articles available on Pubmed and Scielo databases. Results: The prevalence of chemical dependence on propofol, opioids (specially fentanyl and sufentanil) and ketamine is higher among the anesthesiologists, paramedics, and psychiatrists. A meaningful correlation was found between these professionals? chemical dependence and other psychopathologies, including personality disorder, and depression. Such disorders may.

Clinical aspects and treatment of pain in children and adolescents with cancer.

BACKGROUND: The aim of this study was to characterize the clinical aspects and the treatment of mild to severe pain in Brazilian children and adolescents with cancer. We evaluated the importance of classifying patients according to the phase of cancer treatment (diagnosis, treatment, recurrence, and end-of-life palliative care) and the opioid-related side effects. METHODS: An institutional prospective study of 184 episodes of pain in children and adolescents with cancer was conducted. Pain was classified according to its cause, physiopathology and intensity. Treatment was based on the WHO guidelines for cancer pain relief. RESULTS: Pain scales were completed by 77% of the patients. Numerical scales were used by 49% of them. Morphine was given in 111 episodes for 2,758 patient days. Morphine doses had to be escalated when it was given to patients during end-of-life palliative care. Opioids were well tolerated with no severe side effects. Psychological dependence on morphine was found in 2% (2/111) of the cases. Pain control was satisfactory in 97% of the episodes. CONCLUSIONS: The WHO guidelines for cancer pain relief were effective in controlling pain in children and adolescents with cancer. Despite their low socioeconomic level, patients were able to quantify their pain using rating scales.

Riluzole decreases the abstinence syndrome and physical dependence in morphine-dependent mice.

The effects of the antiglutamatergic agent, riluzole, were examined on the antinociceptive action of morphine, on the induction of physical dependence, and on the expression of the abstinence syndrome to the opiate in mice. Morphine was administered as a single dose (200 mg/kg) of a slow-release preparation. Acute and chronic administration of riluzole decreased the analgesic response to morphine, the intensity of abstinence behavior (administered 30 min before a dose of naloxone), and the development of physical dependence (repeatedly administered during the period of chronic morphine treatment).
