Tracking Opioid Prescribing Metrics in Washington State (2012-2017): Differences by County-Level Urban-Rural and Economic Distress Classifications

Opioid prescription patterns in the province of Las Palmas, Canary Islands, Spain (2016-2020): differences between urban and rural areas

Introduction: The use of opioids has increased markedly in the past decades in European countries, especially for treatment of non-cancer pain including painful chronic musculoskeletal conditions. However, there are some notable differences in the relative levels of use between geographical areas and some distinct, context-specific patterns of weak and strong opioid use. The aim of this work is to describe real world trends in dosage forms and population exposure in the prescription opioid use on isolated geographically area: The Canary Islands of Gran Canaria, Lanzarote and Fuerteventura, Spain. For this, several factors such as living in a rural or urban area, population over 65 years of age, population density or socioeconomic status were analyzed. Methods: Data were extracted from the wholesalers who supply the community pharmacies at the population level. Prescription opioid use was measured as defined daily doses (DDD) per 1,000 inhabitants per day. A model based on covariance analysis with two nested fixed factors and one co-variable was used for contrast analysis at different level. Results: The overall DDD per 1000 inhabitants per day and year variation rate in Spain was very similar to that obtained for Gran Canaria and Fuerteventura (0.967 vs. 1.006), although the levels of dispensation were different (14.75 versus 18.24 for Gran Canaria and 12.7 for Fuerteventura, respectively). Lanzarote is completely different in all issues, where the opioid consumption rate remained stable during the study period, but with a decreasing tendency. The dispensation level of strong opioids varied between islands, from 56.41% for Fuerteventura vs. 17.61% for Gran Canaria, although these values remained stable. Tramadol with acetaminophen and Tramadol in monotherapy were the most consumed forms of the weak opioids, whereas Buprenorphine was the most used strong opioid followed by Fentanyl, although demand for it varied between islands, the transdermal formulations were the most frequent pharmaceutical preparation. Conclusion: The differences in prescription opioid use are most likely explained by the opioid prescribing practices in each island, whereas factors such urbanicity level, population age, population density and status socioeconomic does not help to explain the differences in prescription opioid use across rural and urban areas.

Broadband internet subscription rates and opioid prescribing via telemedicine during the COVID-19 pandemic

PURPOSE

In response to the COVID-19 pandemic, the US DEA allowed controlled substance prescriptions to be issued following a telemedicine encounter. This study evaluated changes in opioid prescribing in Kentucky counties with low and high rates of broadband subscription before, during, and after a series of statewide emergency declarations that may have affected health care access.

METHODS

The study used the prescription drug monitoring program to analyze records of opioid analgesic prescriptions dispensed to opioid-naïve individuals in high (N = 26) and low (N = 94) broadband access counties during 3 periods: before a state of emergency (SOE) and executive order (EO) limiting nonemergent health care services (January 2019-February 2020), while the EO was active (March-April 2020), and after health care services began reopening (May-December 2020). Marginal generalized estimating equations-type negative binomial models were fit to compare prescription counts by broadband access over the 3 periods.

FINDINGS

Rates of opioid dispensing to opioid-naïve individuals decreased significantly during the EO, but increased nearly to pre-SOE levels after health care services began reopening. Dispensing rates in low broadband counties were higher than those in high broadband counties during all time periods, although these differences were negligible after adjusting for potential confounders. During the EO, prescriptions were written for longer days' supply in both county types.

CONCLUSIONS

The overall dramatic reduction in opioid prescribing rates should be considered when evaluating annual opioid prescribing trends. However, broadband subscription rate did not appear to influence opioid prescriptions dispensed in Kentucky during the EO.

Opioid use trends in Spain: the case of the island of La Gomera (2016-2019)

This study is an evaluation of prescription opioid use on the island of La Gomera, a mainly rural area, during the period 2016-2019 at various levels. Data were extracted from the wholesalers who supply the community pharmacies at the population level. Prescription opioid use was measured as defined daily doses per 1,000 inhabitants/day (DID) and by the number of units sold per 1,000 inhabitants and year (units sold). This provided an island total of La Gomera's overall prescription of opioids and its rate of change, as well as differences in prescribing at the municipal and health area level. Tramadol with acetaminophen and tramadol in monotherapy were the most consumed by "units sold" parameter, which accounted for 69.48% and 18.59% of the total. The situation was similar for DID, although with lower percentages, but a significant increase was observed in the use of fentanyl and buprenorphine, around 15% in each case. The balance between the uses of weak or strong opioids was different in La Gomera compared to that of Spain as a whole. In Spain, almost 70% of the prescriptions were for weak opioids compared to 58.67% in La Gomera. Fentanyl was the most used strong opioid (16.10%) followed by tapentadol and buprenorphine, around 5% each, whereas in La Gomera, buprenorphine was the most consumed (15.75%) followed by fentanyl (14.87%) and tapentadol (5.82%). These differences in prescription opioid use are most likely explained by prescriber characteristics, whereas the population age, socioeconomic status, or living in rural/urban area are not decisive determinants.

An ethnographic study of opioid use disorder in rural Maine: The problem of pain

This qualitative study was conducted to more fully understand health care providers and community leaders’ perceptions of the opioid crisis in rural Maine. In 2017, Maine continued to have one of the highest opioid overdose death rates in the country, more than double the national average. I (first author) visited eight treatment centers in Maine providing support and treatment to people recovering form Opioid Use Disorder (OUD), shadowing health care providers. I also attended OUD-related meetings held with community leaders. I conducted a total of 33 semi-structured interviews with health care providers, community leaders, and NGOs in the state of Maine. Three themes emerged integrating observations with semi-structured interviews: i) Impact of emergence of new extended release opioids, their prescription patterns, and culture around them; ii) Subjectivity of pain and importance of understanding psychic injury in OUD treatment; iii) Socio-political context and perception of OUD in Maine. Our society’s perception of pain has deep historical and cultural sources that influence the way that pain has been perceived and treated in the medical setting. Resources beyond the medical environment are needed to address pain adequately.

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

Background

Regional 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.

Methods

Data 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.

Results

Among 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.

Conclusion

We found large regional variations in opioid prescribing which probably cannot only be attributed to differences in patient characteristics.

Variation in Abuse-Deterrent Formulation Opioid Prescribing in California, Florida, and Kentucky in 2018

PURPOSE

Abuse-deterrent formulation (ADF) opioid analgesics have been developed as a means to address prescription opioid abuse. ADF opioid use in clinical practice is not well described in the literature. This study characterizes ADF opioid prescribing patterns in 3 diverse states.

METHODS

This study used data from prescription drug monitoring programs (PDMPs) in California, Florida, and Kentucky. The sample includes all ADF opioid prescriptions for patients ≥18 years old during the study period (CY 2018). Standardized prescribing rates were calculated by age, sex, and county rurality. The ADF opioid prescribing rate was calculated per 1,000 adult recipients of opioid analgesics.

FINDINGS

The rate of ADF prescribing per 1,000 adult recipients of opioid analgesics was nearly twice as high in Florida (14.57; 95% CI: 14.44-14.69) than in California (8.30; 95% CI: 8.22-8.37) or Kentucky (8.20; 95% CI: 8.01-8.39). ADF prescribing rates were highest among adults ages 55-74 years and among males. ADF opioid prescribing in rural counties represented a greater proportion of total patients using opioid analgesics than in metro counties in California (RR 1.40; CI: 1.28-1.53). Opposite and less pronounced variation was observed in Kentucky (RR 0.93; 95% CI: 0.88-0.98), and a significant difference was not observed in Florida (RR 0.68; 95% CI: 0.38-1.19).

CONCLUSIONS

There were significant differences in the ADF prescribing rates among the 3 states and in rural versus metro counties within 2 states. ADF opioid prescribing by age and sex showed similar trends within states. Further research is needed to elucidate contextual factors which may lead to prescribing variation.
