First Sero-Molecular Diagnosis of Toxoplasma gondii and Toxocara spp. Infections in the Police Dogs and Their Trainers in Iran.

PURPOSE: Toxoplasma gondii (T. gondii) and Toxocara spp. are two types of parasites that can infect humans and various animals, including dogs. Police dogs and their trainers have a vital role in law enforcement, and their health and well-being are crucial for them to effectively carry out their duties. No study has yet been conducted on the prevalence of T. gondii and Toxocara spp. infections among police dogs and their trainers in Iran. The objective of this study was to determine the sero-molecular prevalence of T. gondii and Toxocara spp. infections in police dogs and their trainers in Tehran, the capital of Iran. METHODS: In Tehran province, the anti-narcotics police have nearly 200 well-trained police dogs. Each dog is assigned a dedicated trainer and upon completing missions, is housed separately in a designated area. In the present study, a total of 150 samples were gathered. These included 50 blood samples from randomly selected police dogs, 50 fecal samples from the same dogs, and 50 blood samples from their trainers. The Modified Agglutination Test (MAT) was performed to detect T. gondii antibodies in dog blood samples and the ELISA system was utilized to identify anti-Toxoplasma and anti-Toxocara antibodies in the sera of the dog trainers. A specific segment of the SAG2 and ITS genes were amplified via nested-PCR in order to molecularly detect T. gondii in human blood samples and Toxocara spp. in dog fecal samples. RESULTS: Regarding serological findings, the prevalence of T. gondii in dog and human blood samples was 4% (2/50) and 10% (5/50), respectively. According to reports, the seroprevalence of Toxocara spp. in human blood samples was 6% (3/50). No statistically significant association was found between the prevalence of the examined parasites and variables (age, sex, and breed) in dogs, as well as the age variable in military personnel. Molecular findings showed that out of the 50 dog fecal samples and 50 human blood samples, there was no presence of Toxocara spp. and T. gondii, respectively. CONCLUSION: Understanding the prevalence of parasitic infections helps public health officials assess the risk to human and animal populations. This information can guide the development of prevention and control measures to reduce the spread of these infections. Overall, the prevalence of parasitic infections, particularly T. gondii and Toxocara spp., in police dogs and their trainers remains uncertain and necessitates further in-depth research.

Deciphering the Causality between Gut Microbiota Dysbiosis and Poisoning by Narcotics and Psychodysleptics: A Mendelian Randomization Analysis.

BACKGROUND: This study investigates the connection between gut microbiota and poisoning caused by narcotics and psychodysleptics, using Mendelian randomization (MR) to explore possible causal relationships. METHODS: The study employed the MR analysis, leveraging genetic variants as instrumental variables to facilitate robust causal inference. Data for gut microbiota was extracted from the MiBioGen study, integrating genome-wide genotyping data with 16S fecal microbiota profiles. Outcome metrics were based on the Finngen study. Genetic instruments were meticulously extracted based on stringent criteria, and harmonized with SNP outcomes associated with "Poisoning by narcotics and psychodysleptics [hallucinogens]". The inverse-variance weighted (IVW) method was utilized for MR analysis, supplemented by sensitivity analyses including MR-Egger Regression, Weighted Median Approach, and Leave-One-Out Cross-Validation. RESULTS: Among various microbial groups, nine showed significant statistical links. Specifically, Class Negativicutes (OR 5.68, 95% CI 2.13-15.16, p = 0.0005) and Order Selenomonadales (OR 5.68, 95% CI 2.13-15.16, p = 0.0005) were notably associated. These findings were consistent across different sensitivity analyses. CONCLUSION: The relationship between gut microbiota and the adverse effects of narcotics and psychodysleptics is an emerging area of research. Our MR study identifies certain microbes that might influence the body's response to these substances. These insights could help in predicting and treating the effects of narcotics and psychodysleptics in the future.

Questionnaire on the Current Status and Awareness of Palliative Medicine by Community Cooperation Pharmacies.

Community cooperation pharmacies are equipped to prepare narcotics and sterile injectable drugs for palliative medicine at home for cancer pain and end-of-life care; however, to the best of our knowledge, the actual status of the system to provide palliative medicine at home has not yet been examined. Therefore, in this study, given that home palliative medicine is one of the accreditation criteria for community cooperation pharmacies, a questionnaire survey was conducted among managing pharmacists engaged in community cooperation pharmacies to investigate the actual status of the system to provide appropriate services, mainly pain management, to patients who need home palliative medicine. An analysis of responses to the questionnaire showed that pharmacists working in community cooperation pharmacies had a high level of understanding of the proper use of rescue doses of medical narcotics and patient guidance. Pharmacists with experience in sterile and injection preparations also had a high level of understanding of palliative medicine. On the other hand, they had a low level of understanding of the WHO method for cancer pain treatment and appropriate suggestions for opioid switching. These results indicate that the creation of learning opportunities, such as training on injectables and prescription designs, for pharmacists in community cooperation pharmacies is one of the measures that may improve their understanding of palliative medicine.

Provider Specialization in Inflammatory Bowel Diseases: Quality of Care and Outcomes.

BACKGROUND & AIMS: Management of inflammatory bowel diseases (IBD) is complex and variation in care has been well-documented. However, the drivers of practice variation remain unexplored. We examined variation based on the treating gastroenterologist's IBD focus (proportion of outpatient visits for IBD). METHODS: We conducted a retrospective cohort of newly diagnosed patients with IBD using data from Optum's deidentified Clinformatics Data Mart Database (2000-2020). The exposure variable was whether the treating gastroenterologist had an IBD focus (>90th percentile of IBD visits/total outpatient visits). We used adjusted regression models to evaluate associations between provider IBD focus and process measures (use of mesalamine, corticosteroid, biologic, and narcotic medications and endoscopic or radiographic imaging) and clinical outcomes (time to IBD-related hospitalization and bowel resection surgery). We tested for change in treatment patterns over time by including an interaction term for study era (2004-2012 vs 2013-2020). RESULTS: The study included 772 children treated by 493 providers and 2864 adults treated by 2076 providers. In children, none of the associations between provider focus and process or outcome measures were significant. In adults, care from an IBD-focused provider was associated with more use of biologics, combination therapy, and imaging and endoscopy, and less mesalamine use for Crohn's disease (P < .05 for all comparisons) but not with other process measures. Biologics were prescribed more frequently and narcotics less frequently during the later era (P < .05 for both). Hospitalization and surgery rates were not associated with IBD focus or era. CONCLUSIONS: IBD care for adults varies by provider specialization. Given the evolving complexity, novel methods may be needed to standardize care.

Impact of narcotics information management system on inappropriate benzodiazepine receptor agonist prescriptions: A quasi-experimental analysis in South Korea.

AIMS: The South Korean government implemented the narcotics information management system (NIMS) on 18 May 2018 to manage benzodiazepine receptor agonists (BzRAs) and narcotics effectively and establish a reporting mechanism for these drugs. This study assessed the effects of NIMS on inappropriate use of BzRAs. METHODS: Using national patient sample data from 2016 to 2020, we analysed adult outpatients who were prescribed oral BzRAs. We conducted a time series and segmented regression analysis using selected indicators to analyse the monthly variations related to the inappropriate use of these medications. RESULTS: The study revealed no significant changes in the indicators of inappropriate BzRA use following the NIMS implementation. Contrary to expectations, there was a significant increase in the proportion of patients exceeding defined daily dose (DDD) and in those receiving concurrent prescriptions of multiple BzRAs, following the implementation of NIMS. The immediate impact of the COVID-19 pandemic was an increase in DDD exceedance; however, overall, this did not significantly affect BzRA use. CONCLUSIONS: The introduction of NIMS did not significantly enhance the management of BzRA misuse. Additional measures, including continuous monitoring, system improvements and comprehensive education for prescribers and patients, are recommended to ensure the appropriate use of psychotropic medications.

National Long-Term Trends in Postoperative Opioid Prescribing in Ambulatory Urology Procedures.

INTRODUCTION: With more than 60% of urological procedures performed in ambulatory settings, it is imperative to understand the current trends in postoperative narcotic prescriptions and their adherence to the guidelines. We studied postoperative opioid-prescribing patterns after selected common urology ambulatory procedures. METHODS: A retrospective cohort was derived from a 10% random sample of enrollees within the IQVIA PharMetrics Plus for Academics database from 2015 to 2021. Patient-level baseline characteristics were collected in the year preceding the index date. Descriptive and bivariate analyses were used to compare patient characteristics from opioid and nonopioid cohorts and those who utilized opioids ≤ 7 days and > 7 days postprocedurally. Trends of opioid and nonopioid use were also investigated and compared. RESULTS: Between 2015 to 2021, 17,817 patients underwent urological ambulatory procedures, of which the majority (90.9%) were endoscopic procedures. Of those, 4077 (22%) were prescribed opioids and 978 (5.4%) patients were given prescription nonopioid (ie, ketorolac) medication. From 2015 to 2021, there was an overall decrease in prescription of opioids from 32% to 19%. The acute fulfillment (within 7 days of the procedure) of opioids had notably declined; however, there is a slight increase in the fulfillment of opioids beyond 7 days. CONCLUSIONS: Within the 7-day postsurgical period after ambulatory procedures, narcotic prescribing habits among urologists are congruent with current initiatives to reduce narcotic use in the setting of the opioid pandemic. However, beyond the 7-day postsurgical period, further guidelines are needed to guide narcotic prescribing habits.

Buprenorphine Use for Analgesia in Palliative Care.

Buprenorphine is a semi-synthetic long-acting partial µ-opioid receptor (MOR) agonist that can be used for chronic pain as a sublingual tablet, transdermal patch (Butrans®), or a buccal film (Belbuca®). Buprenorphine's unique high receptor binding affinity and slow dissociation at the MOR allow for effective analgesia while offering less adverse effects compared to a full agonist opioid, in particular, less concern for respiratory depression and constipation. It is underused in chronic pain and palliative care due to misconceptions and stigma from its use in opioid use disorder (OUD). This case report discusses the unique pharmacology of buprenorphine, including its advantages, disadvantages, available formulations, drug-drug interactions, initiation and conversion strategies, and identifies ideal populations for use, especially within the palliative care patient population.

Narcotic prescribing practices in shoulder surgery before and after the institution of narcotic e-prescribing.

Background: Given the current opioid epidemic, it is crucial to highly regulate the prescription of narcotic medications for pain management. The use of electronic prescriptions (e-scripts) through the hospital's electronic medical record platform allows physicians to fill opioid prescriptions in smaller doses, potentially limiting the total quantity of analgesics patients have access to and decreasing the potential for substance misuse. The purpose of this study is to determine how the implementation of e-scripts changed the quantity of opioids prescribed following shoulder surgeries. Methods: For this single-center retrospective study, data were extracted for all patients aged 18 years or more who received a shoulder procedure between January 2015 and December 2020. Total milligrams of morphine equivalents (MMEs) of opioids prescribed within the 90 days following surgery were compared between 3 cohorts: preimplementation of the 2017 New Jersey Opioid laws (Pre-NJ opioid laws), post-NJ Opioid Laws but pre-escripting, and postimplementation of e-scripting in 2019 (postescripting). Any patient prescribed preoperative opioids, prescribed opioids by nonorthopedic physicians, under the care of a pain management physician, or had a simultaneous nonshoulder procedure was excluded from this study. Results: There were 1857 subjects included in this study; 796 pre-NJ opioid laws, 520 post-NJ opioid laws, pre-escripting, and 541 postescripting. Following implementation of e-scripting on July 1, 2019, there was a significant decrease in total MMEs prescribed (P < .001) from a median of 90 MME (interquartile range 65, 65-130) preimplementation to a median 45 MME (interquartile range 45, 45-90) MME postimplementation Additionally, there was a statistically significant decrease in opioids prescribed for all procedures (P < .001) and for 3 (P < .001) of the 4 orthopedic surgeons included in this study. Conclusion: Our study demonstrated a significant reduction in total MMEs prescribed overall, for all shoulder surgeries, and for the majority of our institution's providers in the postoperative period following the e-scripting implementation in July 2019. E-scripting is a valuable tool in conjunction with education and awareness on the national, institutional, provider, and patient levels to combat the opioid epidemic.

Social network analysis for medical narcotics in South Korea: focusing on patients and healthcare organizations.

BACKGROUND: Medical narcotics must be administered under medical supervision because of their potential for misuse and abuse, leading to more dangerous and addictive substances. The control of medical narcotics requires close monitoring to ensure that they remain safe and effective. This study proposes a methodology that can effectively identify the overprescription of medical narcotics in hospitals and patients. METHODS: Social network analysis (SNA) was applied to prescription networks for medical narcotics. Prescription data were obtained from the Narcotics Information Management System in South Korea, which contains all data on narcotic usage nationwide. Two-mode networks comprising hospitals and patients were constructed based on prescription data from 2019 to 2021 for the three most significant narcotics: appetite suppressants, zolpidem, and propofol. Two-mode networks were then converted into one-mode networks for hospitals. Network structures and characteristics were analyzed to identify hospitals suspected of overprescribing. RESULTS: The SNA identified hospitals that overprescribed medical narcotics. Patients suspected of experiencing narcotic addiction seek treatment in such hospitals. The structure of the network was different for the three narcotics. While appetite suppressants and propofol networks had a more centralized structure, zolpidem networks showed a less centralized but more fragmented structure. During the analysis, two types of hospitals caught our attention: one with a high degree, meaning that potential abusers have frequently visited the hospital, and the other with a high weighted degree, meaning that the hospital may overprescribe. For appetite suppressants, these two types of hospitals matched 84.6%, compared with 30.0% for propofol. In all three narcotics, clinics accounted for the largest share of the network. Patients using appetite suppressants were most likely to visit multiple locations, whereas those using zolpidem and propofol tended to form communities around their neighborhoods. CONCLUSIONS: The significance of this study lies in its analysis of nationwide narcotic use reports and the differences observed across different types of narcotics. The social network structure between hospitals and patients varies depending on the composition of the medical narcotics. Therefore, these characteristics should be considered when controlling medication with narcotics. The results of this study provide guidelines for controlling narcotic use in other countries.

How Does Narcotic Control Impact upon Human Individual Rights: An Islamic and International Human Rights Perspectives.

Illegal trafficking of narcotics and problems associated with illegal substance abuse have attracted great deal of attention over the years. However, there are concerns about how to solve this problem while still respecting individual rights. In general terms, it has been alleged by numerous international observers that in many instances human rights have not been fully respected or observed in the fight against illicit drugs. When it comes to Shari'a law, the fundamental premise is that narcotics abuse and trafficking is clearly in violation of Islamic principles. This article highlights the importance of adopting a human rights-based approach to policies regarding narcotics and discusses the potential conflict and the State's obligation to enforce laws which protect their citizens with individual citizen's rights. It focuses on Islamic laws and takes Saudi Arabia as an example given the fact that the Saudi Arabia bases its constitution on Sharia.

Internet-based, continuously available Narcotics Anonymous meetings: a new resource for access to Twelve Step support for abstinence.

Background: A Zoom-based website was developed in 2020 that offers continuous access to online Narcotics Anonymous (NA) meetings for the first time. This website provides immediate access for persons with substance use disorder to support abstinence from substance-related addictive disorders.Objectives: This study is designed to characterize attendees employing this online format; to evaluate their experiences for gaining support to maintain abstinence; and to compare the 24/7 experience to face-to-face (FF) meetings they attend.Methods: An anonymous 33-item survey was made available on the 24/7 NA website that links to the 24/7 meetings. Persons accessing the site could choose to fill out the survey.Results: 530 respondents completed the survey (64.9% female/35.1% male). Most had stable prior involvement in NA. They had attended more 24/7 meetings (14.9, SD 19.7) than FF meetings (4.6, SD 7.8) in the previous month. 86% had previously attended FF meetings, 48% had served as sponsors, and 92% reported that the 24/7 meetings were more comfortable for them than the FF meetings (p < .001, Cohen's d = 0.65) and more supportive of abstinence (p < .001, Cohen's d = 0.91). Of the respondents, 8% were still using drugs, of whom 52% had previously completed some of the Twelve Steps.Conclusions: The 24/7 format provides a new and easily accessible way for NA members to gain support for abstinence and is positively rated by attendees seeking support for recovery from substance use disorders. It may serve as a valuable adjunct to the traditional FF format.

Managing an epidemic within a pandemic: orthopedic opioid prescribing trends during COVID-19.

INTRODUCTION: In response to the opioid epidemic, a multitude of policy and clinical-guideline based interventions were launched to combat physician overprescribing. However, the sudden rise of the Covid-19 pandemic disrupted all aspects of healthcare delivery. The purpose of this study was to evaluate how opioid prescribing patterns changed during the Covid-19 pandemic within a large multispecialty orthopedic practice. MATERIALS AND METHODS: A retrospective review of 1,048,559 patient encounters from January 1, 2015 to December 31, 2022 at a single orthopedic practice was performed. Primary outcomes were the percent of encounters with opioids prescribed and total morphine milligram equivalents (MMEs) per opioid prescription. Differences in outcomes were assessed by calendar year. Encounters were then divided into two groups: pre-Covid (1/1/2019-2/29/2020) and Covid (3/1/2020-12/31/2022). Univariate analyses were used to evaluate differences in diagnoses and outcomes between periods. Multivariate analysis was performed to assess changes in outcomes during Covid after controlling for differences in diagnoses. Statistical significance was assessed at p < 0.05. RESULTS: The percentage of encounters with opioids prescribed decreased from a high of 4.0% in 2015 to a low of 1.6% in 2021 and 2022 (p < 0.001). MMEs per prescription decreased from 283.6 ± 213.2 in 2015 to a low of 138.6 ± 100.4 in 2019 (p < 0.001). After adjusting for diagnoses, no significant differences in either opioid prescribing rates (post-COVID OR = 0.997, p = 0.893) or MMEs (post-COVID ß = 2.726, p = 0.206) were observed between the pre- and post-COVID periods. CONCLUSION: During the Covid-19 pandemic opioid prescribing levels remained below historical averages. While continued efforts are needed to minimize opioid overprescribing, it appears that the significant progress made toward this goal was not lost during the pandemic era.

Continuous flow local anesthetic wound infusion for post-operative analgesia following kidney transplantation.

BACKGROUND: Some patients with end stage renal disease are or will become narcotic-dependent. Chronic narcotic use is associated with increased graft loss and mortality following kidney transplantation. We aimed to compare the efficacy of continuous flow local anesthetic wound infusion pumps (CFLAP) with patient controlled analgesia pumps (PCA) in reducing inpatient narcotic consumption in patients undergoing kidney transplantation. MATERIALS AND METHODS: In this single-center, retrospective analysis of patients undergoing kidney transplantation, we collected demographic and operative data, peri-operative outcomes, complications, and inpatient oral morphine milligram equivalent (OME) consumption. RESULTS: Four hundred and ninety-eight patients underwent kidney transplantation from 2020 to 2022. 296 (59%) historical control patients received a PCA for postoperative pain control and the next 202 (41%) patients received a CFLAP. Median age [53.5 vs. 56.0 years, p = .08] and BMI [29.5 vs. 28.9 kg/m2, p = .17] were similar. Total OME requirement was lower in the CFLAP group [2.5 vs. 34 mg, p < .001]. Wound-related complications were higher in the CFLAP group [5.9% vs. 2.7%, p = .03]. Two (.9%) patients in the CFLAP group experienced cardiac arrhythmia due to local anesthetic toxicity and required lipid infusion. CONCLUSIONS: Compared to PCA, CFLAP provided a 93% reduction in OME consumption with a small increase in the wound-related complication rate. The utility of local anesthetic pumps may also be applicable to patients undergoing any unilateral abdominal or pelvic incision.

LC-MS/MS analysis of 11-nor-9-carboxy-hexahydrocannabinol (HHC-COOH) and 11-hydroxy-hexahydrocannabinol (HHC-OH) for verification of hexahydrocannabinol (HHC) intake.

Natural and semi-synthetic cannabinoid analogs are getting increasing media attention for their recreative use as an alternative to traditional cannabis, in Sweden as well as internationally. To investigate an increasing number of urine samples incoming to our clinical laboratory that were screening positive, using a CEDIA THC-COOH immunoassay from ThermoFisher Scientific, but then testing negative using GC-MS based verification analysis, we developed an LC-MS/MS-method for verification of hexahydrocannabinol (HHC) and Δ8-tetrahydrocannabinol. Assessment of HHC intake was based on identification of the following four metabolites: 11-nor-9(R)-carboxy-hexahydrocannabinol (R-HHC-COOH), 11-nor-9(S)-carboxy-hexahydrocannabinol (S-HHC-COOH), 11-hydroxy-9(R)-hexahydrocannabinol (R-HHC-OH) and 11-hydroxy-9(S)-hexahydrocannabinol (S-HHC-OH). Out of 46 urine samples analysed in this study, 44 showed presence of HHC-metabolites, which indicate HHC as the main explanation for an increased number of negative verifications for THC-COOH. In these samples, the HHC-OH metabolites occurred at a higher concentration than R-HHC-COOH while S-HHC-COOH was only detected in few samples at low concentrations. R-HHC-COOH and S-HHC-COOH can easily be added to a pre-existing verification method for THC-COOH, and still show acceptable results, while HHC-OH requires an enzyme capable of hydrolysing the ether glucuronide bond.

Multimodal Pain Management After Outpatient Orthopedic Hand Surgery: A Prospective Randomized Trial.

Purpose: Opioid stewardship ensures effective pain management while avoiding overprescribing of opioids after surgery. This prospective randomized study investigates the efficacy of a multimodal postoperative pain regimen compared to a traditional opioid-only pain regimen following elective outpatient orthopedic hand surgery. We hypothesized that patients receiving multimodal pain management would consume fewer opioids and report greater satisfaction than patients receiving only opioids. Methods: Consecutive patients undergoing outpatient hand and upper extremity surgery performed by two board-certified fellowship-trained orthopedic hand surgeons at one institution were recruited and randomized into either a study or control group. The study group received a standing multimodal postoperative regimen consisting of scheduled oral acetaminophen and naproxen as well as oxycodone to be taken as needed. The control group received only oxycodone to be taken as needed. Postoperatively, daily pain levels, medication usage, refills, satisfaction, and adverse events were recorded. Descriptive statistics were performed. Results: Of the 112 patients enrolled, 54 were randomized to the control group, and 58 were randomized to the study group. Study and control group patients did not differ significantly based on daily average pain scores or daily worst pain scores. However, study group patients reported fewer average daily oxycodone intake and total oxycodone pill count (7.0 vs 2.4 total pills, P <.005). In addition, the study group patients were more likely to report satisfaction with their postoperative pain control than control regimen patient's and were more likely to use the same pain regimen again if required. Conclusion: A multimodal postoperative pain regimen reduces opioid usage and has higher patient satisfaction rates in comparison to traditional opioid-only regimens. Use of multimodal pain regimens that use nonopioids, such as acetaminophen and naproxen, over an opioid should be considered for postoperative pain after orthopedic hand surgery. Level of Evidence: Therapeutic II.

Does the type of lower extremity fracture affect long-term opioid usage? A meta-analysis.

INTRODUCTION:  Patients recovering from musculoskeletal trauma have a heightened risk of opioid dependence and misuse, as these medications are typically required for pain management. The purpose of this meta-analysis was to examine the association between fracture type and chronic opioid use following fracture fixation in patients who sustain lower extremity trauma. MATERIALS AND METHODS: A meta-analysis was performed using PubMed and Web of Science to identify articles reporting chronic opioid use in patients recovering from surgery for lower extremity fractures. 732 articles were identified using keyword and MeSH search functions, and 9 met selection criteria. Studies were included in the final analysis if they reported the number of patients who remained on opioids 6 months after surgery for a specific lower extremity fracture (chronic usage). Logistic regressions and descriptive analyses were performed to determine the rate of chronic opioid use within each fracture type and if age, year, country of origin of study, or pre-admission opioid use influenced chronic opioid use following surgery. RESULTS: Bicondylar and unicondylar tibial-plateau fractures had the largest percentage of patients that become chronic opioid users (29.7-35.2%), followed by hip (27.8%), ankle (19.7%), femoral-shaft (18.5%), pilon (17.2%), tibial-shaft (13.8%), and simple ankle fractures (2.8-4.7%).Most opioid-naive samples had significantly lower rates of chronic opioid use after surgery (2-9%, 95% CI) when compared to samples that allowed pre-admission opioid use (13-50%, 95% CI). There were no significant associations between post-operative chronic opioid use and age, year, or country of origin of study. CONCLUSIONS:  Patients with lower extremity fractures have substantial risk of becoming chronic opioid users. Even the lowest rates of chronic opioid use identified in this meta-analysis are higher than those in the general population. It is important that orthopedic surgeons tailor pain-management protocols to decrease opioid usage after lower extremity trauma.

Impact of the Narcotics Information Management System on Opioid Use Among Outpatients With Musculoskeletal and Connective Tissue Disorders: Quasi-Experimental Study Using Interrupted Time Series.

BACKGROUND: Opioids have traditionally been used to manage acute or terminal pain. However, their prolonged use has the potential for abuse, misuse, and addiction. South Korea introduced a new health care IT system named the Narcotics Information Management System (NIMS) with the objective of managing all aspects of opioid use, including manufacturing, distribution, sales, disposal, etc. OBJECTIVE: This study aimed to assess the impact of NIMS on opioid use. METHODS: We conducted an analysis using national claims data from 45,582 patients diagnosed with musculoskeletal and connective tissue disorders between 2016 and 2020. Our approach included using an interrupted time-series analysis and constructing segmented regression models. Within these models, we considered the primary intervention to be the implementation of NIMS, while we treated the COVID-19 outbreak as the secondary event. To comprehensively assess inappropriate opioid use, we examined 4 key indicators, as established in previous studies: (1) the proportion of patients on high-dose opioid treatment, (2) the proportion of patients receiving opioid prescriptions from multiple providers, (3) the overlap rate of opioid prescriptions per patient, and (4) the naloxone use rate among opioid users. RESULTS: During the study period, there was a general trend of increasing opioid use. After the implementation of NIMS, significant increases were observed in the trend of the proportion of patients on high-dose opioid treatment (coefficient=0.0271; P=.01) and in the level of the proportion of patients receiving opioid prescriptions from multiple providers (coefficient=0.6252; P=.004). An abrupt decline was seen in the level of the naloxone use rate among opioid users (coefficient=-0.2968; P=.04). While these changes were statistically significant, their clinical significance appears to be minor. No significant changes were observed after both the implementation of NIMS and the COVID-19 outbreak. CONCLUSIONS: This study suggests that, in its current form, the NIMS may not have brought significant improvements to the identified indicators of opioid overuse and misuse. Additionally, the COVID-19 outbreak exhibited no significant influence on opioid use patterns. The absence of real-time monitoring feature within the NIMS could be a key contributing factor. Further exploration and enhancements are needed to maximize the NIMS' impact on curbing inappropriate opioid use.

Hospital-Wide Adherence to Postsurgical Opioid Prescribing Guidelines: A Retrospective Cohort Study.

INTRODUCTION: Lowering opioid prescription doses and quantity decreases the risk of chronic opioid usage. A tool was inserted into the brief operative note for the surgeon to assess the severity of pain associated with the procedure. We studied surgeon adherence to current opioid-prescribing recommendations. METHODS: Retrospective cohort study with 5486 patients were included in the study population. Each patient's prescription was scored yes or no for adherence on total morphine milligram equivalents (MMEs) and days prescribed with the selection in the brief operative note. The entire study population was tested for an increase from the null-hypothesis "benchmark" value of 75% using a one-sided exact binomial test of a single proportion with P < 0.05. This procedure was repeated for subgroups, with P < 0.01. RESULTS: Adherence to guidelines was higher than the 75% benchmark for "total MMEs prescribed" (79.5%; P < 0.001), but lower for "number of days prescribed" (63.5%; P > 0.999). Surgeries with severe predicted pain showed the highest adherence toward total MMEs prescribed at 87.1%, followed by moderate (80.5%) and mild (74.5%). Severe cases also showed the highest adherence in number of days prescribed (92.4%). Adherence to total MMEs prescribed was highest among attending physicians (88.1%) and lowest among residents/fellows (76.6%). CONCLUSIONS: Adherence to current guidelines was 79.5% for MMEs prescribed but only 63.5% for days prescribed. Compliance with guidelines was better for severe procedures than mild or moderate. Differences were seen across surgical departments. While an improvement from previous reports, further improvement is needed to reduce the number of days of opioids prescribed and increase compliance with recommended guidelines.
