What Changes Have Occurred in Opioid Prescriptions and the Prescribers of Opioids Before TKA and THA?: A Large National Registry Study

BACKGROUND: Opioid use before TKA or THA is linked to a higher risk of revision surgery and less functional improvement. In Western countries, the frequency of preoperative opioid use has varied, and robust information on temporal changes in opioid prescriptions over time (in the months before surgery as well as annual changes) and among prescribers is necessary to pinpoint opportunities to improve on low-value care patterns, and when they are recognized, to target physician populations for intervention strategies. QUESTIONS/PURPOSES: (1) What proportion of patients undergoing arthroplasties receive an opioid prescription in the year before TKA or THA, and what were the preoperative opioid prescription rates over time between 2013 and 2018? (2) Does the preoperative prescription rate vary between 12 and 10 months and between 3 and 1 months in the year before TKA or THA, and did it change between 2013 and 2018? (3) Which medical professionals were the main prescribers of preoperative opioids 1 year before TKA or THA? METHODS: This was a large-database study drawn from longitudinally maintained national registry sources in the Netherlands. The Dutch Foundation for Pharmaceutical Statistics was linked to the Dutch Arthroplasty Register from 2013 to 2018. TKAs and THAs performed because of osteoarthritis in patients older than 18 years, which were also uniquely linked by age, gender, patient postcode, and low-molecular weight heparin use, were eligible. Between 2013 and 2018, 146,052 TKAs were performed: 96% (139,998) of the TKAs were performed for osteoarthritis in patients older than 18 years; of them, 56% (78,282) were excluded because of our linkage criteria. Some of the linked arthroplasties could not be linked to a community pharmacy, which was necessary to follow patients over time, leaving 28% (40,989) of the initial TKAs as our study population. Between 2013 and 2018, 174,116 THAs were performed: 86% (150,574) were performed for osteoarthritis in patients older than 18 years, one arthroplasty was excluded because of an outlier opioid dose, and a further 57% (85,724 of 150,574) were excluded because of our linkage criteria. Some of the linked arthroplasties could not be linked to a community pharmacy, leaving 28% (42,689 of 150,574) of THAs, which were performed between 2013 and 2018. For both TKA and THA, the mean age before surgery was 68 years, and roughly 60% of the population were women. We calculated the proportion of patients undergoing arthroplasties who had at least one opioid prescription in the year before arthroplasty and compared data from 2013 to 2018. Opioid prescription rates are given as defined daily dosages and morphine milligram equivalents (MMEs) per arthroplasty. Opioid prescriptions were assessed by preoperative quarter and by operation year. Possible changes over time in opioid exposure were investigated using linear regression, adjusted for age and gender, in which the month of operation since January 2013 was used as the determinant and MME as the outcome. This was done for all opioids combined and per opioid type. Possible changes in opioid prescription rates in the year before arthroplasty were assessed by comparing the time period of 1 to 3 months before surgery with the other quarters. Additionally, preoperative prescriptions per operation year were assessed per prescriber category: general practitioners, orthopaedic surgeons, rheumatologists, and others. All analyses were stratified by TKA or THA. RESULTS: The proportion of patients undergoing arthroplasties who had an opioid prescription before TKA increased from 25% (1079 of 4298) in 2013 to 28% (2097 of 7460) in 2018 (difference 3% [95% CI 1.35% to 4.65%]; p < 0.001), and before THA increased from 25% (1111 to 4451) to 30% (2323 to 7625) (difference 5% [95% CI 3.8% to 7.2%]; p < 0.001). The mean preoperative opioid prescription rate increased over time between 2013 and 2018 for both TKA and THA. For TKA, an adjusted monthly increase of 3.96 MME was observed (95% CI 1.8 to 6.1 MME; p < 0.001). For THA, the monthly increase was 3.8 MME (95% CI 1.5 to 6.0; p = 0.001. For both TKA and THA, there was a monthly increase in the preoperative oxycodone rate (3.8 MME [95% CI 2.5 to 5.1]; p < 0.001 and 3.6 [95% CI 2.6 to 4.7]; p < 0.001, respectively). For TKA, but not for THA, there was a monthly decrease in tramadol prescriptions (-0.6 MME [95% CI -1.0 to -0.2]; p = 0.006). Regarding the opioids prescribed in the year before surgery, there was a mean increase of 48 MME (95% CI 39.3 to 56.7 MME; p < 0.001) for TKA between 10 and 12 months and the last 3 months before surgery. For THA, this increase was 121 MME (95% CI 110 to 131 MME; p < 0.001). Regarding possible differences between 2013 and 2018, we only found differences in the period 10 to 12 months before TKA (mean difference 61 MME [95% CI 19.2 to 103.3]; p = 0.004) and the period 7 to 9 months before TKA (mean difference 66 MME [95% CI 22.0 to 110.9]; p = 0.003). For THA, there was an increase in the MMEs prescribed between 2013 and 2018 for all four quarters, with mean differences ranging from 43.9 to 55.4 MME (p < 0.05). The average proportion of preoperative opioid prescriptions prescribed by general practitioners ranged between 82% and 86% (41,037 of 49,855 for TKA and 49,137 of 57,289 for THA), between 4% and 6% (2924 of 49,855 for TKA and 2461 of 57,289 for THA), by orthopaedic surgeons, 1% by rheumatologists (409 of 49,855 for TKA and 370 of 57,289 for THA), and between 9% and 11% by other physicians (5485 of 49,855 for TKA and 5321 of 57,289 for THA). Prescriptions by orthopaedic surgeons increased over time, from 3% to 7% for THA (difference 4% [95% CI 3.6 to 4.9]) and 4% to 10% for TKA (difference 6% [95% CI 5% to 7%]; p < 0.001). CONCLUSION: Between 2013 and 2018, preoperative opioid prescriptions increased in the Netherlands, mainly because of a shift to more oxycodone prescriptions. We also observed an increase in opioid prescriptions in the year before surgery. Although general practitioners were the main prescribers of preoperative oxycodone, prescriptions by orthopaedic surgeons also increased during the study period. Orthopaedic surgeons should address opioid use and its associated negative effects in preoperative consultations. More intradisciplinary collaboration seems important to limit the prescribing of preoperative opioids. Additionally, research is necessary to assess whether opioid cessation before surgery reduces the risk of adverse outcomes. LEVEL OF EVIDENCE: Level III, therapeutic study

Out-of-hospital opioid prescriptions after knee and hip arthroplasty: prescribers and the first prescribed opioid

Background: We determined the first prescribed opioid and the prescribers of opioids after knee and hip arthroplasty (KA/HA) between 2013 and 2018 in the Netherlands. We also evaluated whether the first prescribed opioid dose was associated with the total dispensed dose and long-term opioid use in the first postoperative year. Methods: The Dutch Foundation for Pharmaceutical Statistics was linked to the Dutch Arthroplasty Register. Stratified for KA/HA, the first out-of-hospital opioid within 30 days of operation was quantified as median morphine milligram equivalent (MME). Opioid prescribers were orthopaedic surgeons, general practitioners, rheumatologists, anaesthesiologists, and other physicians. Long-term use was defined as ≥1 opioid prescription for >90 postoperative days. We used linear and logistic regression analyses adjusted for confounders. Results: Seventy percent of 46 106 KAs and 51% of the 42 893 HAs were prescribed ≥1 opioid. Oxycodone increased as first prescribed opioid (from 44% to 85%) whereas tramadol decreased (64–11%), but their dosage remained stable (stronger opioids were preferred by prescribers). An increase in the first prescription of 1% MME resulted in a 0.43%/0.37% increase in total MME (KA/HA, respectively). A 100 MME increase in dose of the first dispensed opioid had a small effect on long-term use (prevalence: 25% KA, 20% HA) (odds ratio=1.02/1.01 for KA/HA, respectively). Orthopaedic surgeons increasingly prescribed the first prescription between 2013 and 2018 (44–69%). General practitioners mostly prescribed consecutive prescriptions (>50%). Conclusion: Oxycodone increased as first out-of-hospital prescription between 2013 and 2018. The dose of the first prescribed opioid was associated with the total dose and a small increased risk of prolonged use. First prescriptions were mostly written by orthopaedic surgeons and consecutive prescriptions by general practitioners

Development of a Multivariate Prediction Model for Early-Onset Bronchiolitis Obliterans Syndrome and Restrictive Allograft Syndrome in Lung Transplantation.

Chronic lung allograft dysfunction and its main phenotypes, bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS), are major causes of mortality after lung transplantation (LT). RAS and early-onset BOS, developing within 3 years after LT, are associated with particularly inferior clinical outcomes. Prediction models for early-onset BOS and RAS have not been previously described. LT recipients of the French and Swiss transplant cohorts were eligible for inclusion in the SysCLAD cohort if they were alive with at least 2 years of follow-up but less than 3 years, or if they died or were retransplanted at any time less than 3 years. These patients were assessed for early-onset BOS, RAS, or stable allograft function by an adjudication committee. Baseline characteristics, data on surgery, immunosuppression, and year-1 follow-up were collected. Prediction models for BOS and RAS were developed using multivariate logistic regression and multivariate multinomial analysis. Among patients fulfilling the eligibility criteria, we identified 149 stable, 51 BOS, and 30 RAS subjects. The best prediction model for early-onset BOS and RAS included the underlying diagnosis, induction treatment, immunosuppression, and year-1 class II donor-specific antibodies (DSAs). Within this model, class II DSAs were associated with BOS and RAS, whereas pre-LT diagnoses of interstitial lung disease and chronic obstructive pulmonary disease were associated with RAS. Although these findings need further validation, results indicate that specific baseline and year-1 parameters may serve as predictors of BOS or RAS by 3 years post-LT. Their identification may allow intervention or guide risk stratification, aiming for an individualized patient management approach

Opioid prescribing patterns after arthroplasty of the knee and hip: a Dutch nationwide cohort study from 2013 to 2018

BACKGROUND AND PURPOSE: Numbers on opioid prescriptions over time in arthroplasty patients are currently lacking. Therefore we determined the annual opioid prescribing rate in patients who received a hip/knee arthroplasty (HA/KA) between 2013 and 2018. PATIENTS AND METHODS: The Dutch Foundation for Pharmaceutical Statistics, which provides national coverage of medication prescriptions, was linked to the Dutch Arthroplasty Register, which provides arthroplasty procedures. The opioid prescription rates were expressed as the number of defined daily dosages (DDD) and morphine milligram equivalent (MME) per person year (PY) and stratified for primary and revision arthroplasty. Amongst subgroups for age (< 75; ≥ 75 years) and sex for primary osteoarthritis arthroplasties, prescription rates stratified for opioid type (weak/strong) and prevalent preoperative opioid prescriptions (yes/no) were assessed. RESULTS: 48,051 primary KAs and 53,964 HAs were included, and 3,540 revision KAs and 4,118 HAs. In 2013, after primary KA 58% were dispensed ≥ 1 opioid within the first year; this increased to 89% in 2018. For primary HA these numbers increased from 38% to 75%. In KAs the prescription rates increased from 13.1 DDD/PY to 14.4 DDD/PY, mainly due to oxycodone prescriptions (2.9 DDD/PY to 7.3 DDD/PY), while tramadol decreased (7.3 DDD/PY to 4.6 DDD/PY). The number of MME/PY also increased (888 MME/PY to 1224 MME/PY). Similar changes were observed for HA and revision arthroplasties. Irrespective of joint, prescription of opioid medication increased over time, with highest levels in groups with preoperative opioid prescriptions while weak opioid prescriptions decreased. INTERPRETATION: In the Netherlands, between 2013 and 2018 postoperative opioid prescriptions after KA and HA increased, mainly due to increased oxycodone prescriptions with highest levels after surgeries with preoperative prescriptions

The global retinoblastoma outcome study : a prospective, cluster-based analysis of 4064 patients from 149 countries

DATA SHARING : The study data will become available online once all analyses are complete.BACKGROUND : Retinoblastoma is the most common intraocular cancer worldwide. There is some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these differences have not been assessed on a global scale. We aimed to report 3-year outcomes for children with retinoblastoma globally and to investigate factors associated with survival. METHODS : We did a prospective cluster-based analysis of treatment-naive patients with retinoblastoma who were diagnosed between Jan 1, 2017, and Dec 31, 2017, then treated and followed up for 3 years. Patients were recruited from 260 specialised treatment centres worldwide. Data were obtained from participating centres on primary and additional treatments, duration of follow-up, metastasis, eye globe salvage, and survival outcome. We analysed time to death and time to enucleation with Cox regression models. FINDINGS : The cohort included 4064 children from 149 countries. The median age at diagnosis was 23·2 months (IQR 11·0–36·5). Extraocular tumour spread (cT4 of the cTNMH classification) at diagnosis was reported in five (0·8%) of 636 children from high-income countries, 55 (5·4%) of 1027 children from upper-middle-income countries, 342 (19·7%) of 1738 children from lower-middle-income countries, and 196 (42·9%) of 457 children from low-income countries. Enucleation surgery was available for all children and intravenous chemotherapy was available for 4014 (98·8%) of 4064 children. The 3-year survival rate was 99·5% (95% CI 98·8–100·0) for children from high-income countries, 91·2% (89·5–93·0) for children from upper-middle-income countries, 80·3% (78·3–82·3) for children from lower-middle-income countries, and 57·3% (52·1-63·0) for children from low-income countries. On analysis, independent factors for worse survival were residence in low-income countries compared to high-income countries (hazard ratio 16·67; 95% CI 4·76–50·00), cT4 advanced tumour compared to cT1 (8·98; 4·44–18·18), and older age at diagnosis in children up to 3 years (1·38 per year; 1·23–1·56). For children aged 3–7 years, the mortality risk decreased slightly (p=0·0104 for the change in slope). INTERPRETATION : This study, estimated to include approximately half of all new retinoblastoma cases worldwide in 2017, shows profound inequity in survival of children depending on the national income level of their country of residence. In high-income countries, death from retinoblastoma is rare, whereas in low-income countries estimated 3-year survival is just over 50%. Although essential treatments are available in nearly all countries, early diagnosis and treatment in low-income countries are key to improving survival outcomes.The Queen Elizabeth Diamond Jubilee Trust and the Wellcome Trust.https://www.thelancet.com/journals/langlo/homeam2023Paediatrics and Child Healt

Sleeve lobectomy may provide better outcomes than pneumonectomy for non-small cell lung cancer. A decade in a nationwide study

International audienceIntroduction: Whenever feasible, sleeve lobectomy is recommended to avoid pneumonectomy for lung cancer, but these guidelines are based on limited retrospective series. The aim of our study was to compare outcomes following sleeve lobectomy and pneumonectomy using data from a national database. Methods: From 2005 to 2014, 941 sleeve lobectomy and 5318 pneumonectomy patients were recorded in the French database Epithor. Propensity score was generated with 15 pretreatment variables and used to create balanced groups with matching (794 matches) and inverse probability of treatment weighting (standardized difference was 0 for matching, and 0.0025 after weighting). Odds ratio (OR) of postoperative complications and mortality and hazard ratio (HR) for overall survival and disease-free survival were calculated using propensity adjustment techniques and a sensitivity analysis. Results: Postoperative mortality after sleeve resection was similar to that after pneumonectomy (matching OR, 1.24; P = .4; weighting OR, 0.77; P = .4) despite significantly lower odds of pulmonary complications with pneumonectomy (matching OR, 0.4; P < .0001; weighting OR, 0.12; P < .001). The adjusted HR for death after pneumonectomy was significantly higher when analyzed using matched analysis but not with weighting (matching HR, 1.63; P = .002; weighting HR, 0.97; P = .92). The same was true for disease-free survival (matching HR, 1.49; P = .01; weighting HR, 1.03; P = .84). Conclusions: Despite early differences in perioperative pulmonary outcomes favoring pneumonectomy, early overall and disease-free survival was in favor of sleeve lobectomy in the matched analysis but not the weighted analysis. In our opinion, when it is technically feasible, sleeve lobectomy should be the preferred technique
