Differences In Opioid Prescribing Research Articles

Differences in opioid prescriptions by race among U.S. older adults with a hip fracture transitioning to community care.

Appropriate pain management can facilitate rehabilitation after a hip fracture as patients transition back to the community setting. Differences in opioid prescribing by race may exist during this critical transition period. We conducted a retrospective cohort study of older adult U.S. Medicare beneficiaries with a hip fracture to examine whether the receipt and dose of opioids differs between Black and White patients as they transitioned back to the community setting. We stratified beneficiaries by whether they received institutional post-acute care (PAC). Outcomes were (1) receipt of an opioid and (2) opioid doses in the first 90 days in the community in milligram morphine equivalents (MMEs; also presented in mg oxycodone). We estimated relative rates and risk differences of opioid receipt and dose differences using Poisson and linear regression models, respectively, using the parametric g-formula to standardize for age and sex. We identified 164,170 older adults with hip fracture (mean age = 82.7 years; 75% female; 72% with PAC; 46% with opioid use after fracture). Overall use of opioids in the community was similar between Black and white beneficiaries. Black beneficiaries had lower average doses in their first 90 days in both total cumulative doses (PAC group: 165 [95% CI -264 to -69] fewer MMEs [-248 mg oxycodone]; no PAC: 167 [95% CI -274 to -62] fewer MMEs [-251 mg oxycodone]) and average MME per days' supply of medication (PAC: -3.0 [-4.6 to -1.4] fewer MMEs per day [-4.5 mg oxycodone]; no PAC: -4.7 [-4.6 to -1.4] fewer MMEs per day [-7.1 mg oxycodone]). In secondary analyses, Asian beneficiaries experienced the greatest differences (e.g., 617-653 fewer cumulative mg oxycodone). Racial differences exist in pain management for Medicare beneficiaries after a hip fracture. Future work should examine whether these differences result in disparities in short- and long-term health outcomes.

The association between primary care appointment lengths and opioid prescribing for common pain conditions

BackgroundWhile brief duration primary care appointments may improve access, they also limit the time clinicians spend evaluating painful conditions. This study aimed to evaluate whether 15-minute primary care appointments resulted in higher rates of opioid prescribing when compared to ≥ 30-minute appointments.MethodsWe performed a retrospective cohort study using electronic health record (EHR), pharmacy, and administrative scheduling data from five primary care practices in Minnesota. Adult patients seen for acute Evaluation & Management visits between 10/1/2015 and 9/30/2017 scheduled for 15-minute appointments were propensity score matched to those scheduled for ≥ 30-minutes. Sub-groups were analyzed to include patients with acute and chronic pain conditions and prior opioid exposure. Multivariate logistic regression was performed to examine the effects of appointment length on the likelihood of an opioid being prescribed, adjusting for covariates including ethnicity, race, sex, marital status, and prior ED visits and hospitalizations for all conditions.ResultsWe identified 45,471 eligible acute primary care visits during the study period with 2.7% (N = 1233) of the visits scheduled for 15 min and 98.2% (N = 44,238) scheduled for 30 min or longer. Rates of opioid prescribing were significantly lower for opioid naive patients with acute pain scheduled in 15-minute appointments when compared to appointments of 30 min of longer (OR 0.55, 95% CI 0.35–0.84). There were no significant differences in opioid prescribing among other sub-groups.ConclusionsFor selected indications and for selected patients, shorter duration appointments may not result in greater rates of opioid prescribing for common painful conditions.

Opioid utilization after orthopaedic trauma hospitalization among Medicaid-insured adults.

Opioids are vital to pain management and sedation after trauma-related hospitalization. However, there are many confounding clinical, social, and environmental factors that exacerbate pain, post-injury care needs, and receipt of opioid prescriptions following orthopaedic trauma. This retrospective study sought to characterize differences in opioid prescribing and dosing in a national Medicaid eligible sample from 2010-2018. The study population included adults, discharged after orthopaedic trauma hospitalization, and receiving an opioid prescription within 30 days of discharge. Patients were identified using the International Classification of Diseases (ICD-9; ICD-10) codes for inpatient diagnosis and procedure. Filled opioid prescriptions were identified from National Drug Codes and converted to morphine milligram equivalents (MME). Opioid receipt and dosage (e.g., morphine milligram equivalents [MME]) were examined as the main outcomes using regressions and analyzed by year, sex, race/ethnicity, residence rurality-urbanicity, and geographic region. The study population consisted of 86,091 injured Medicaid-enrolled adults; 35.3% received an opioid prescription within 30 days of discharge. Male patients (OR = 1.12, 95% CI: 1.07-1.18) and those between 31-50 years of age (OR = 1.15, 95% CI: 1.08-1.22) were found to have increased odds ratio of receiving an opioid within 30 days of discharge, compared to female and younger patients, respectively. Patients with disabilities (OR = 0.75, 95% CI: 0.71-0.80), prolonged hospitalizations, and both Black (OR = 0.87, 95% CI: 0.83-0.92) and Hispanic patients (OR = 0.72, 95% CI: 0.66-0.77), relative to white patients, had lower odds ratio of receiving an opioid prescription following trauma. Additionally, Black and Hispanic patients received lower prescription doses compared to white patients. Individuals hospitalized in the Southeastern United States and those between the ages of 51-65 age group were found to be prescribed lower average daily MME. There were significant variations in opioid prescribing practices by race, sex, and region. National guidelines for use of opioids and other pain management interventions in adults after trauma hospitalization may help limit practice variation and reduce implicit bias and potential harms in outpatient opioid usage.

The Association of Cognitive Status and Post-Operative Opioid Prescribing in Older Adults.

To examine the differences in opioid prescribing by cognitive status following common elective surgical procedures among Medicare beneficiaries. Older individuals commonly experience changes in cognition with age. Although opioid prescribing is common after surgery, differences in opioid prescribing after surgery by cognitive status are poorly understood. We conducted a retrospective analysis of patients ≥65 years participating in the Health and Retirement Study (HRS) linked with Medicare claims data who underwent surgeries between January 2007 and November 2016 and had cognitive assessments before the index operation. Cognitive status was defined as normal cognition, mild cognitive impairment (MCI), or dementia. Outcomes assessed were initial perioperative opioid fill rates, refill rates, and high-risk prescriptions fill rates. The total amount of opioids filled during the 30-day postdischarge period was also assessed. Adjusted rates were estimated for patient factors using the Cochran-Armitage test for trend. Among the 1874 patients included in the analysis, 68% had normal cognition, 21.3% had MCI, and 10.7% had dementia. Patients with normal cognition (58.1%) and MCI (54.5%) had higher initial preoperative fill rates than patients with dementia (33.5%) (P < 0.001). Overall, patients with dementia had similar opioid refill rates (21%) to patients with normal cognition (24.1%) and MCI (26.5%) (P = 0.322). Although prior opioid exposure did not differ by cognitive status (P = 0.171), among patients with high chronic preoperative use, those with dementia had lower adjusted prescription sizes filled within 30 days following discharge (281 OME) than patients with normal cognition (2147 OME) and MCI (774 OME) (P < 0.001; P = 0.009 respectively). Among opioid-naive patients, patients with dementia also filled smaller prescription sizes (97 OME) compared to patients with normal cognition (205 OME) and patients with MCI (173 OME) (P < 0.001 and P = 0.019, respectively). Patients with dementia are less likely to receive postoperative prescriptions, less likely to refill prescriptions, and receive prescriptions of smaller sizes compared to patients with normal cognition or MCI. A cognitive assessment is an additional tool surgeons can use to determine a patient's individualized postoperative pain control plan.

HSD87 Racial Disparities in Opioid Prescribing By Patient and Prescriber Race

Racial disparities in opioid prescribing for pain have been reported for the past two decades. While the disparity has decreased over time, there remains a gap in low back pain (LBP). For example, past studies have shown that black patients are less likely to receive an opioid prescription relative to white patients for LBP. This study seeks to explore whether differences in opioid prescribing exist not just by patient race, but also by prescriber race.

Are There Differences in Postoperative Opioid Prescribing Across Racial and Ethnic Groups? Assessment of an Academic Health System.

Previous studies have demonstrated racial disparities in opioid prescribing in emergency departments and after surgical procedures. Orthopaedic surgeons account for a large proportion of dispensed opioid prescriptions, yet there are few data investigating whether racial or ethnic disparities exist in opioid dispensing after orthopaedic procedures. (1) Are Black, Hispanic or Latino, or Asian or Pacific Islander (PI) patients less likely than non-Hispanic White patients to receive an opioid prescription after an orthopaedic procedure in an academic United States health system? (2) Of the patients who do receive a postoperative opioid prescription, do Black, Hispanic or Latino, or Asian or PI patients receive a lower analgesic dose than non-Hispanic White patients when analyzed by type of procedure performed? Between January 2017 and March 2021, 60,782 patients underwent an orthopaedic surgical procedure at one of the six Penn Medicine healthcare system hospitals. Of these patients, we considered patients who had not been prescribed an opioid within 1 year eligible for the study, resulting in 61% (36,854) of patients. A total of 40% (24,106) of patients were excluded because they did not undergo one of the top eight most-common orthopaedic procedures studied or their procedure was not performed by a Penn Medicine faculty member. Missing data consisted of 382 patients who had no race or ethnicity listed in their record or declined to provide a race or ethnicity; these patients were excluded. This left 12,366 patients for analysis. Sixty-five percent (8076) of patients identified as non-Hispanic White, 27% (3289) identified as Black, 3% (372) identified as Hispanic or Latino, 3% (318) identified as Asian or PI, and 3% (311) identified as another race ("other"). Prescription dosages were converted to total morphine milligram equivalents for analysis. Statistical differences in receipt of a postoperative opioid prescription were assessed with multivariate logistic regression models within procedure, adjusted for age, gender, and type of healthcare insurance. Kruskal-Wallis tests were used to assess for differences in the total morphine milligram equivalent dosage of the prescription, stratified by procedure. Almost all patients (95% [11,770 of 12,366]) received an opioid prescription. After risk adjustment, we found no differences in the odds of Black (odds ratio 0.94 [95% confidence interval 0.78 to 1.15]; p = 0.68), Hispanic or Latino (OR 0.75 [95% CI 0.47 to 1.20]; p = 0.18), Asian or PI (OR 1.00 [95% CI 0.58 to 1.74]; p = 0.96), or other-race patients (OR 1.33 [95% CI 0.72 to 2.47]; p = 0.26) receiving a postoperative opioid prescription compared with non-Hispanic White patients. There were no race or ethnicity differences in the median morphine milligram equivalent dose of postoperative opioid analgesics prescribed (p > 0.1 for all eight procedures) based on procedure. In this academic health system, we did not find any differences in opioid prescribing after common orthopaedic procedures by patient race or ethnicity. A potential explanation is the use of surgical pathways in our orthopaedic department. Formal standardized opioid prescribing guidelines may reduce variability in opioid prescribing. Level III, therapeutic study.

De-Implementing Opioids for Dental Extractions (DIODE): a multi-clinic, cluster-randomized trial of clinical decision support strategies in dentistry

BackgroundOpioid pain relievers are commonly prescribed following dental extractions, but evidence shows that non-opioid analgesics often provide adequate pain relief with fewer risks. The current study examined clinical decision support (CDS) as a tool for de-implementing opioid prescribing in dentistry.MethodsThis prospective, cluster-randomized trial examined CDS for dental pain management at 22 HealthPartners Dental Group clinics in Minnesota. Dental providers (n = 49) were randomized to deliver care using CDS, CDS with patient education materials (CDS-E), or standard practice (SP). Randomization was stratified by provider type (dentist vs. oral surgeon) and baseline opioid prescribing volume. Patient records of dental extractions were examined for January 2019 through May 2021, representing a 12-month baseline and 15-month intervention period (N = 12,924). Opioid prescription at the visit (no vs. yes) was the primary outcome. Data were analyzed using generalized linear mixed models, adjusting for patient sex and age, extraction complexity, and baseline prescribing strata (volume and provider type).ResultsPatients were 56.2% female, with a mean age of 46.7 (SD = 20.0) years. Providers were 8% oral surgeons, 57% female, and with a mean age of 43.7 (SD = 11.2) years. There were significant decreases in opioid prescribing during the study (P < 0.001), representing a continuation of pre-existing trends to reduce opioid prescribing in these dental practices. There were no significant differences in opioid prescribing between CDS and SP (OR = 1.29; 97.5% CI = 0.93, 1.79; P = 0.08), or CDS-E and SP arms (OR = 1.27; 97.5% CI = 0.86, 1.79; P = 0.18). The direction of the association favored greater reductions in opioid prescribing in the SP arm. Despite training and implementation support, utilization of the CDS was low, particularly among oral surgeons, who were significantly more likely than other dentists to prescribe opioids. Among non-oral surgeon providers with the opportunity to access it, CDS utilization was not significantly associated with opioid prescribing.ConclusionsEquipping dentists with CDS resources, whether alone or accompanied by patient education materials, did not accelerate reductions in opioid prescribing beyond those observed in standard practice. Strategies are needed to enhance CDS utilization for patient care and safety surrounding analgesia following dental extractions.Trial registrationClinicaltrials.gov, NCT03584789.

Opioid Prescribing for Kidney Stone Formers Undergoing Stone Removal

Background: Kidney stone formers may have episodes of severe pain and be at increased risk of narcotic use. Alabama has a high rate of opioid use. Within, we examine differences in opioid prescribing for kidney stone formers requiring stone removal procedures. Methods: A retrospective review was conducted from June 2013 to July 2019. Twenty-five patients with recurrent cystine stones were randomly matched by age, gender, and procedure to 25 recurrent non-cystine and 25 first-time non-cystine stone formers. Patients underwent ureteroscopic stone removal and percutaneous nephrolithotomy. Opioids prescribed were identified through medical record review and the prescription drug monitoring program (PDMP) database. Morphine milligram equivalents (MMEs) standardized opioid utilization. Results: Opioids prescribed at discharge significantly decreased (mean MME ± SD), 216.8 ± 125.9 for 2013 - 2016 and 124.2 ± 106.1 for 2017 - 2019 (P &lt; 0.001) corresponding to implementation of an institutional opioid stewardship program. Opioids prescribed within 180 days of stone removal were similar amongst all three cohorts, mean 3,377.6 MME/patient. Over this 6-year time period, there was no difference in total amount of opioids prescribed for each cohort, mean 27,987.8 MME. The majority of prescriptions (56.4%) and MME prescribed (91.9 %) were from pain management and primary care providers. Conclusions: MME prescribed for stone removal in an environment of high utilization has not declined and is not influenced by stone disease complexity. An opioid stewardship program was associated with decreased opioids prescribed by the surgeons conducting stone removal but had a negligible overall influence. The latter is driven by other care providers. World J Nephrol Urol. 2022;11(1):10-17 doi: https://doi.org/10.14740/wjnu428

Influence of provider type on chronic pain prescribing patterns A systematic review.

Chronic pain affects 100 million Americans and is most often treated in primary care, where the health care provider shortage remains a challenge. Nurse practitioners (NPs) represent a growing solution, yet their patterns of chronic pain management are understudied. Additionally, prescriptive authority limitations in many states limit NPs from prescribing opioids and often exist due to concerns of NP-driven opioid overprescribing. Little evidence on NP pain management prescribing patterns exists to address these issues. Systematic review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, to examine opioid and nonopioid prescribing patterns of physicians, NPs, and physician assistants (PAs) in primary care. Eligible studies scored ≥60% on the Joanna Briggs Institute Critical Appraisal checklist. Searches within PubMed, Embase, CINAHL, and Web of Science. Three themes were elucidated: 1) opioid prescribing in primary care, 2) similarities and differences in opioid prescribing by provider type, and 3) nonopioid pain management strategies. All provider groups had similar opioid prescribing patterns, although NPs and PAs may be slightly less likely to prescribe opioids than physicians. Although some studies suggested that NPs/PAs had higher opioid prescribing rates compared with physicians, methodological flaws may undermine these conclusions. Evidence is also lacking on nonopioid prescribing patterns across disciplines. Nurse practitioner/PA prescriptive authority limitations may not be as effective of a solution for addressing opioid overprescribing as transdisciplinary interventions targeting the highest subset of opioid prescribers. Future research should examine prescribing patterns of nonopioid, including nonpharmacologic, therapies.

Association of Patient Race and Ethnicity With Differences in Opioid Prescribing by Primary Care Physicians for Older Adults With New Low Back Pain

Substantial patient racial and ethnic differences in opioid prescribing have been documented, but how much of these differences were attributable to physicians prescribing opioids differently to patients of racial and ethnic minority groups is unknown, particularly during the first wave of the opioid epidemic when the dangers of opioid prescribing and use were not as well known. To examine associations of patient race and ethnicity with differences in opioid prescribing by the same primary care physician (PCP) for new low back pain episodes among older adults from 2007 to 2014. This cross-sectional study used Medicare data of PCP office visits by Medicare beneficiaries who were 66 years or older with new low back pain. Prescribing of any opioid in the first year of a new low back pain episode (days 1-365) and subsequent long-term use of an opioid (prescribed for ≥180 days in days 366-730). Among the study population of 274 771 patients (mean [SD] age, 77.1 [7.2] years; 192 105 [69.9%] women) with new low back pain, 15 285 (6%) were Asian or Pacific Islander, 16 079 (6%) were Black, 21 289 (8%) were Hispanic, and 222 118 (81%) were White, cared for by 63 494 physicians. In adjusted analysis, on average, 11.5% of the White patients (95% CI, 11.4 to 11.6) received an opioid prescription in the first year of new low back pain. The same prescribing physician was 1.5 percentage points (PP; 95% CI, -2.2 PP to -0.8 PP) less likely to prescribe an opioid if the patient was Black, 2.7 PP (95% CI, -3.5 PP to -1.8 PP) less likely if the patient was Asian or Pacific Islander, and 1.0 PP (95% CI, -1.7 PP to -0.3 PP) less likely if the patient was Hispanic. The same physician was more likely to prescribe a prescription nonsteroidal anti-inflammatory drug to a patient of a racial or ethnic minority group. White patients with new low back pain were more likely to develop subsequent long-term opioid use than patients of racial and ethnic minority groups (eg, 1.8% for White patients vs 0.5% for Hispanic patients). This cross-sectional study found that from 2007 to 2014, primary care physicians prescribed opioids for new low back pain more often to White patients than to patients of racial and ethnic minority groups. These results suggest that there may have been unequal treatment of pain by physicians when less was known about the morbidity associated with opioid use.

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.

Opioid-Prescribing Practices Between Total Knee and Hip Arthroplasty in an Outpatient Versus Inpatient Setting.

Despite trends showing increases in the utilization of outpatient (OP) ambulatory surgery centers (ASCs) and decreases in the utilization of inpatient (IP) facilities for total knee arthroplasty (TKA) and total hip arthroplasty (THA), little is known about opioid prescribing for these procedures between each setting. This study evaluated differences in opioid prescribing and consumption between OP ASC and IP settings for elective TKA and THA surgeries over a 1-year period. Data collection also included pain and satisfaction of pain control postsurgery. In an OP ASC, analysis revealed a significant decrease in pills prescribed (p < .001, p < .001) and consumed (p < .001, p < .001) for TKA and THA, respectively. There was a significant decrease in the morphine equivalence units prescribed (p < .001, p < .001) and consumed (p < .001, p < .001) for TKA and THA, respectively. For TKA, pain was significantly lower (p = .018) and satisfaction of pain control was significantly higher (p = .007). For THA, pain (p = .374) and satisfaction of pain control (p = .173) were similar between the settings. Benefits of performing these surgeries in an OP ASC setting are patients having similar or lower levels of pain and having similar or higher satisfaction of pain control. Patients are also prescribed and consume less opioids. This has important implications for healthcare systems.

Association between sex and perioperative opioid prescribing for total joint arthroplasty: a retrospective population-based study

BackgroundScarce data exist on differential opioid prescribing between men and women in the pre-, peri-, and postoperative phases of care among patients undergoing total hip/knee arthroplasty (THA/TKA). MethodsIn this retrospective population-based study, Truven Health MarketScan claims data were used to establish differences between men and women in (1) opioid prescribing in the year before THA/TKA surgery, (2) the amount of opioids prescribed at discharge, and (3) chronic opioid prescribing (3–12 months after surgery). Multivariable regression models measured odds ratios (OR) with 95% confidence intervals (95% CI). ResultsAmong 29 038 THAs (42% men) and 48 523 TKAs (52% men) men (compared with women) were less likely to receive an opioid prescription in the year before surgery (54% vs 60%, and 54% vs 60% for THA and TKA, respectively); P<0.001. However, in multivariable analyses male sex was associated with higher total opioid dosages prescribed at discharge after THA (OR=1.04; 95% CI 1.03, 1.06) and TKA (OR=1.05; 95% CI 1.04, 1.06); both P<0.001. Chronic opioid prescribing was found in 10% of the cohort (THA: n=2333; TKA: n=5365). Here, men demonstrated lower odds of persistent opioid prescribing specifically after THA (OR=0.90; 95% CI 0.82, 0.99) but not TKA (OR=0.96; 95% CI 0.90, 1.02); P=0.026 and P=0.207, respectively. ConclusionsWe found sex-based differences in opioid prescribing across all phases of care for THA/TKA. The results highlight temporal opportunities for targeted interventions to improve outcomes after total joint arthroplasty, particularly for women, and to decrease chronic opioid prescribing.

The impact of standard postoperative opioid prescribing guidelines on racial differences in opioid prescribing: A retrospective review

BackgroundRacial disparities in opioid prescribing are widely documented, though few studies assess racial differences in the postoperative setting specifically. We hypothesized standard opioid prescribing schedules reduce total opioids prescribed postoperatively and mitigate racial variation in postoperative opioid prescribing. MethodsThis is a retrospective review of adult general surgery cases at a large, public academic institution. Standard opioid prescribing schedules were implemented across general surgery services for common procedures in late 2018 at various timepoints. Interrupted time series analysis was used to compare mean biweekly discharge morphine milligram equivalents prescribed in the preintervention (Jan–Jun 2018) versus postintervention (Jan–Jun 2019) periods for Black and White patients. Linear regression was used to compare mean difference in discharge morphine milligram equivalents among White and Black patients in each study period, while controlling for demographics, chronic opioid use, and procedure/service. ResultsA total of 2,961 cases were analyzed: 1,441 preintervention and 1,520 postintervention. Procedural frequencies, proportion of Black patients (17% Black), and chronic opioid exposure (7% chronic users) were similar across time periods. Interrupted time series analysis showed significantly lower mean level of morphine milligram equivalents prescribed postintervention compared with the predicted nonintervention trend for both Black and White patients. Adjusted analysis showed on average in 2018 Black patients received significantly higher morphine milligram equivalents than White patients (+19 morphine milligram equivalents, 95% confidence interval 0.5–36.5). There was no significant difference in 2019 (–8 morphine milligram equivalents, 95% confidence interval –20.5 to 4.6). ConclusionStandard opioid prescribing schedules were associated with the elimination of racial differences in postoperative opioid prescribing after common general surgery procedures, while also reducing total opioids prescribed. We hypothesize standard opioid prescribing schedules may mitigate the effect of implicit bias in prescribing.

Regional Differences in Opioid Prescribing in Germany - Results of an Analysis of Health Insurance Data of 57 Million Adult People.

BackgroundRegional variations of opioid use have been reported from many countries. The objective of this study was to examine opioid prescribing patterns in Germany including low- and high-potency opioids (LPO and HPO) focusing on regional differences.MethodsData source was the “Information system for health care data” comprising statutory health insurance funds data for about 70 million Germans of all ages. For 2010, we received aggregated data (by age, sex, federal state and district) of Germans (18+) who had been prescribed at least one opioid including the number of prescribed packages. For each stratum, we further received the number of insured persons. We calculated LPO and HPO prevalences and the mean number of prescribed packages.ResultsAmong 57 million adult Germans (mean age: 50.2 years, 53.8% female), opioid prevalences were 38.7 per 1000 persons for LPOs and 12.8 for HPOs. Prevalences rose with increasing age and were higher in women than in men. On average, LPO users were prescribed fewer packages than HPO users (3.5 vs 7.0). LPO use was highest in the eastern states ranging from 32.9 per 1000 persons (Hamburg) to 47.2 (Saxony-Anhalt). HPOs were most often prescribed in the North and in the East with prevalences varying between 10.6 per 1000 persons (Baden-Württemberg) and 16.9 (Mecklenburg-Western Pomerania). On the district level, prevalences varied by the factors 2.6 and 3.2 for LPOs and HPOs, respectively.ConclusionWe found large regional variations in opioid prescribing which probably cannot only be attributed to differences in patient characteristics.

Rural/Urban Differences in the Predictors of Opioid Prescribing Rates Among Medicare Part D Beneficiaries 65 Years of Age and Older.

While research has been done comparing rural/urban differences in opioid prescribing to the disabled Medicare Part D population, research on opioid prescribing among the aged Medicare Part D population is lacking. This study aims to fill this gap by exploring the predictors of opioid prescribing to aged Medicare Part D beneficiaries and investigating whether these predictors vary across rural and urban areas. This is an analysis of ZIP Codes in the continental United States (18,126 ZIP Codes) utilizing 2017 data from Centers for Medicare & Medicaid Services. The analytic approach includes aspatial descriptive analysis, exploratory spatial analysis with geographically weighted regression, and explanatory analysis with spatial error regime modeling. Both beneficiary and prescriber characteristics play an important role in determining opioid prescribing rates in urban ZIP Codes, but most of them fail to explain the opioid prescribing rates in rural ZIP Codes. We identify potential spatial nonstationarity in opioid prescribing rates, indicating the complex nature of opioid-related issues. This means that the same stimulus may not lead to the same change in opioid prescribing rates, because the change may be place specific. By understanding the rural/urban differences in the predictors of opioid prescribing, place-specific policies can be developed that can guide more informed opioid prescribing practices and necessary interventions.

Surgeon experience and opioid prescribing

BackgroundWe evaluated the effects of surgeon characteristics such as surgeon experience on differences in opioid prescribing after surgery. MethodsWe evaluated a 20% national sample of Medicare beneficiaries ≥65 years old who underwent 15 different types of surgery to identify surgeon characteristics associated with opioid prescription size filled within seven days of discharge using a multi-level linear model. Results174,141 patients and 13,828 surgeons met inclusion criteria. 53.8% of patients filled an opioid prescription within seven days postoperatively. The amount of opioids prescribed after surgery was highest for patients whose surgeons were early in practice (i.e. 0-7 years in practice). Surgeon credentials, type of surgery, and geographic region were associated with differing sizes of opioid fills postoperatively. ConclusionsSurgeon characteristics such as cumulative years of practice contribute to differences in prescribing behavior after surgery. These findings can help develop strategic interventions to enhance opioid stewardship.

National gender differences in the prescribing of opioid medications from 2006 to 2015.

To identify gender differences in opioid prescribing from ambulatory care settings and identify factors associated with prescribing of opioids for men and women. Retrospective analysis of data from The National Ambulatory Medical Care Survey from January 1, 2006 to December 31, 2015. Eligible patients were at least 18 years old on the date of the physician office visit. Data were collected on patient demographics and clinical factors. Data were analyzed using bivariate and multivariate logistic regression models to explore differences in opioid prescribing among men and women. Due to the large sample size, the significance level was set to p < 0.001. Opioid prescribing during an office visit. A total of 322 957 ambulatory care visits for adults were included in the analysis representing 7.8 billion weighted visits nationally. In 771 601 088 (9.8 percent) visits, an opioid was prescribed. Women received an opioid prescription at 9.4 percent of visits compared to 10.4 percent of visits for men. Gender differences for factors including age, region, payment method, and pain diagnosis were observed (p < 0.001). Women had a higher number of visits with an opioid (449 277 925 vs 322 323 163), but men had higher odds of being prescribed an opioid (OR: 1.214; CI: 1.214-1.214). Men are more likely to be prescribed an opioid as compared to women, but women are being prescribed more opioids overall. Gender differences should be further explored to develop gender-specific interventions to reduce opioid prescribing.

Racial and Ethnic Disparities in Opioid Prescribing for Long Bone Fractures at Discharge From the Emergency Department: A Cross-sectional Analysis of 22 Centers From a Health Care Delivery System in Northern California

We examine racial and ethnic differences in opioid prescribing and dosing for long bone fractures at emergency department (ED) discharge. We conducted an electronic health records-based cross-sectional study of adults with long bone fractures who presented to the ED across 22 sites from a health care delivery system (2016 to 2017). We examined differences in opioid prescribing at ED discharge and, among patients with a prescription, differences in opioid dosing (measured as morphine milligram equivalents) by race/ethnicity, using regression modeling with statistical adjustment for patient, fracture, and prescriber characteristics. A total of 11,576 patients with long bone fractures were included in the study; 64.4% were non-Hispanic white; 16.4%, 7.3%, 5.8%, and 5.1%, respectively, were Hispanic, Asian, black, and of other or unknown race; and 65.6% received an opioid at discharge. After adjusting for other factors, rates of opioid prescribing were not different by race/ethnicity; however, among patients with an opioid prescription, total morphine milligram equivalent units prescribed were 4.3%, 6.0%, and 8.1% less for Hispanics, blacks, and Asians relative to non-Hispanic whites. Racial and ethnic minority groups with long bone fractures receive similar frequencies of opioid prescriptions at discharge, with a small potency difference. How this affects pain relief and why it happens is unclear.
