User perspectives on outreach opioid substitution treatment among street-entrenched people who use drugs in Denmark

Background The COVID-19 pandemic had many serious consequences for vulnerable populations, but it also gave rise to innovations and changes of established ways of providing services for such populations. In Copenhagen, Denmark outreach opioid agonist therapy (OAT) was such an innovation. Methods Based on qualitative interviews with 15 individuals who received outreach OAT this article describes this new service and presents OAT clients’ experiences of previous OAT and outreach OAT. Analytically the article draws on literature about people who use drugs’ experiences of barriers when wanting to access drug treatment and other services. Results The participants had experienced significant systemic and social barriers in relation to outreach OAT. Outreach OAT helped to minimize both types of barriers. It also created new opportunities for providing care because treatment took place in participants’ own environments. Conclusion Outreach OAT has the potential to minimize treatment barriers for some of the most vulnerable people who use drugs. It is however also important to review and possibly change system design, guidelines, and practices of the existing system to better accommodate the program to the needs of vulnerable people.

Application of the waiting time distribution in a nationwide screening of real-world dermatology drug utilization for aberrant use patterns.

Inappropriate use of medicines may have critical consequences from individual, public health, and economic perspectives. Discovering wrongful medicine use may require intentional surveillance or screening. The objectives of this study were to: (i) apply and evaluate the waiting time distribution (WTD) method as a screening tool for identifying aberrant drug use and (ii) evaluate the nationwide use of Dermatology drugs in Denmark for signals of aberrant drug use. Dermatology drug use data from the Danish nationwide healthcare registries from 2018 to 2020 were used to produce WTDs that were analyzed for drug use patterns. The method provides estimates of the prevalence and incidence and enables estimation of mean treatment duration, drug relapse, and unexpected drug prescribing. The study included 2 027 889 individual drug users and analyzed 6 141 449 prescriptions. The analysis included approximately 100 dermatology drugs and drug categories and produced 56 WTD drug curves. The WTD patterns and epidemiological estimates confirmed that most drugs are used as intended and revealed few unexpected patterns for further investigation. Three unexpected findings were identified concerning (i) short-term use that would entail suboptimal clinical efficiency for minoxidil, (ii) sub-optimal use of topical tacrolimus, and (iii) potential undesirable increase in short-course doxycycline treatments. In Denmark, dermatology drugs are predominantly used as expected, with few unexpected use patterns identified. Targeted specific follow-up on the identified signals is necessary for conclusions about inappropriate use. The findings suggest that the WTD method is applicable for screening for aberrant drug use.

Twenty-Three-Year Trends in the Use of Potentially Nephrotoxic Drugs in Denmark.

The occurrence of acute and chronic kidney diseases has been rising in the last decades. Although drug use is a common risk factor for impaired kidney function, changes in utilization of potential nephrotoxic drugs have received little attention. To describe temporal trends in the utilization of potentially nephrotoxic drugs in Denmark between 1999 and 2021. Specific drugs known or suspected to be nephrotoxic were identified in the literature. Data on the sold defined daily doses (DDDs) of potentially nephrotoxic drugs between 1999 and 2021 were retrieved using the Danish Register of Medical Product Statistics. Trends in sales of DDDs per 1000 inhabitants per day were tabulated and illustrated graphically. From 1999 to 2021, the total sale of all selected drugs increased from 286 to 457 DDDs per 1000 inhabitants per day. The overall sale reached a preliminary peak in 2012 with 449 DDDs per 1000 inhabitants per day and remained relatively stable thereafter until reaching an all-time high in 2021 with 457 DDDs per 1000 inhabitants per day. Contributing with the majority in volume, sales of drugs inhibiting the renin-angiotensin-aldosterone system (RAAS) increased dramatically throughout the period. The same was observed for acetaminophen, methotrexate, tacrolimus, and iodinated contrast dye. In contrast, the sales of diuretics, acetylsalicylic acid, and ciclosporin decreased during the last decade of the study period. From 1999-2021 considerable changes in sales of potentially nephrotoxic drugs were observed. In general, the sales increased, in volume predominated by RAAS inhibiting drugs. This increase in sales of potential nephrotoxins could contribute to an increasing occurrence of kidney diseases.

Use of low-dose quetiapine increases the risk of major adverse cardiovascular events: results from a nationwide active comparator-controlled cohort study.

At standard doses used for schizophrenia or bipolar disorder, quetiapine has been associated with weight gain and increased levels of triglycerides,to-tal cholesterol and low-density lipoprotein (LDL) cholesterol, which are risk factors for cardiovascular morbidity and mortality. However, this drug is also commonly used off-label at low doses for anxiolytic or hypnotic purposes, and its cardiovascular safety at these doses is unknown. We aimed to assess the risk of major adverse cardiovascular events with use of low-dose quetiapine compared to use of Z-drug hypnotics in a nationwide, active comparator-controlled cohort study. The cohort included new users of either drugs in Denmark from 2003 to 2017, aged 18-85 years, without history of ischemic stroke, myocardial infarction, cancer, and severe mental illness. The main outcome was the occurrence of major adverse cardiovascular events, defined as non-fatal myocardial infarction or ischemic stroke, or death from cardiovascular causes. Selective serotonin reuptake inhibitors (SSRIs) were used as an alternative comparator in sensitivity analyses. Altogether, we compared 60,566 low-dose quetiapine users with 454,567 Z-drug users, followed for 890,198 person-years in intent-to-treat analysis, and 330,334 person-years in as-treated analysis. In intention-to-treat analysis, low-dose quetiapine was associated with an increased risk of major adverse cardiovascular events (adjusted hazard ratio, aHR=1.13, 95% CI: 1.02-1.24, p=0.014) and cardiovascular death (aHR=1.26, 95% CI: 1.11-1.43, p<0.001). In as-treated analysis, continuous low-dose quetiapine use was associated with increased risk of major adverse cardiovascular events (aHR=1.52, 95% CI: 1.35-1.70, p<0.001), non-fatal ischemic stroke (aHR=1.37, 95% CI: 1.13-1.68, p=0.002) and cardiovascular death (aHR=1.90, 95% CI: 1.64-2.19, p<0.001). The risk of major adverse cardiovascular events was greater in women (aHR=1.28, p=0.02) and those aged ≥65 years at initiation (aHR=1.24, p<0.001). Compared to SSRIs, low-dose quetiapine use was associated with an increased risk of major adverse cardiovascular events (aHR=1.42, p<0.001), non-fatal ischemic stroke (aHR=1.27, p=0.0028) and cardiovascular death (aHR=1.72, p<0.001). So, we conclude that the use of low-dose quetiapine is associated with an increased risk of major adverse cardiovascular events, especially in women and the elderly. On the basis of these findings, we suggest that use of off-label low-dose quetiapine for sedative or hypnotic purposes should be discouraged.

Prescription opioids among older adults: ten years of data across five countries

BackgroundOpioid use has increased globally in the recent decade. Although pain remains a significant problem among older adults, susceptibility to opioid-related harms highlights the importance of careful opioid therapy monitoring on individual and societal levels. We aimed to describe the trends of prescription opioid utilisation among residents aged ≥65 in all Nordic countries during 2009–2018.MethodsWe conducted cross-sectional measurements of opioid utilisation in 2009–2018 from nationwide registers of dispensed drugs in Denmark, Finland, Iceland, Norway, and Sweden. The measures included annual opioid prevalence, defined daily doses (DDDs) per 1000 inhabitants per day (DIDs), and morphine milligram equivalents (MMEs) per user per day.ResultsFrom 2009 to 2018, an average of 808,584 of adults aged ≥65 used opioids yearly in all five countries; an average annual prevalence of 17.0%. During this time period, the prevalence decreased in Denmark, Norway, and Sweden due to declining codeine and/or tramadol use. Iceland had the highest opioid prevalence in 2009 (30.2%), increasing to 31.7% in 2018. In the same period, DIDs decreased in all five countries, and ranged from 28.3 in Finland to 58.5 in Denmark in 2009, and from 23.0 in Finland to 54.6 in Iceland in 2018. MMEs/user/day ranged from 4.4 in Iceland to 19.6 in Denmark in 2009, and from 4.6 in Iceland to 18.8 in Denmark in 2018. In Finland, Norway, and Sweden, MMEs/user/day increased from 2009 to 2018, mainly due to increasing oxycodone utilisation.ConclusionsThe stable or decreasing opioid utilisation prevalence among a majority of older adults across the Nordic countries coincides with an increase in treatment intensity in 2009–2018. We found large cross-national differences despite similarities across the countries’ cultures and healthcare systems. For the aged population, national efforts should be placed on improving pain management and monitoring future trends of especially oxycodone utilisation.

Antipsychotic drug use in Greenland and Denmark: longitudinal and cross-sectional data

Purpose The aim of this study was to compare the consumption of antipsychotic drugs in Denmark and Greenland between 2014 and 2019. We also investigated the use of antipsychotic medication for schizophrenic and non-affective psychotic patients in both countries. Methods This study was performed as a register study using data from the medical register in Denmark and Greenland. A cross-sectional study on the prescription of antipsychotic drugs for psychotic patients (F 20–29) in Greenland in September 2020 was also conducted. Results The prevalence of antipsychotic drug consumption between 2014 and 2019 was higher in Greenland (average 16.9 DDD/1000/day) compared to Denmark (average 9.3 DDD/1000/day) and the consumption increased in Greenland remarkably. Olanzapine was the most widely used drug in both countries and Clozapine consumption was twice as high in Greenland as in Denmark (1.3 versus 0.6 DDD/1000/day). The mean dose of antipsychotics in schizophrenic and non-affective psychotic patients was higher in Greenland than in Denmark and this difference was greatest among institutional residents. In Greenland, 59% of institutional residents received 2 or 3 DDD/day while only 43% in Denmark received it. Polypharmacy was common in both countries. Conclusion The total consumption and the main dose of antipsychotics in schizophrenic patients was higher in Greenland than in Denmark. Factors contributing to the differences noted appear to be a combination of age and gender differences among patients in the two countries. Socio-economic differences, and differences in treatment options can contribute to the differences and must be investigated further.

How I treat immune thrombocytopenia – a global view

How I treat immune thrombocytopenia – a global view

Use of Clopidogrel and Proton Pump Inhibitors Alone or in Combinations in Persons with Diabetes in Denmark; Potential for CYP2C19 Genotype-Guided Drug Therapy.

Background: Clopidogrel and proton pump inhibitors (PPIs) are among the most used drugs in Denmark for which there exists pharmacogenomics (PGx)-based dosing guidelines and FDA annotations. In this study, we further scrutinized the use of clopidogrel and PPIs when prescriptions were redeemed from Danish Pharmacies alone or in combination in the Danish population and among persons with diabetes in Denmark. The focus deals with the potential of applying PGx-guided antiplatelet therapy taking both drug–drug interactions (DDI) and drug–gene interactions (DGI) into account. Methods: The Danish Register of Medicinal Product Statistics was the source to retrieve consumption data. Results: The consumption of PPIs and clopidogrel in terms of prevalence (users/1000 inhabitants) increased over a five-year period by 6.3% to 103.1 (PPIs) and by 41.7% to 22.1 (clopidogrel), respectively. The prevalence of the use of clopidogrel and PPIs in persons with diabetes are 3.8 and 2.1–2.8 times higher compared to the general population. When redeemed in combination, the prevalence increased to 4.7. The most used combination was clopidogrel and pantoprazole. Conclusions: The use of clopidogrel and PPIs either alone or in combination is quite widespread, in particular among the elderly and persons with diabetes. This further supports the emerging need of accessing and accounting for not only DDI but also for applying PGx-guided drug therapy in clinical decision making for antiplatelet therapy with clopidogrel having a particular focus on persons with diabetes and the elderly.

Drug Use in Denmark for Drugs Having Pharmacogenomics (PGx) Based Dosing Guidelines from CPIC or DPWG for CYP2D6 and CYP2C19 Drug-Gene Pairs: Perspectives for Introducing PGx Test to Polypharmacy Patients.

Background: The cytochrome P450 drug metabolizing enzymes CYP2D6 and CYP2C19 are the major targets for pharmacogenomics (PGx) testing and determining for drug response. Clinical dosing guidelines for specific drug-gene interactions (DGI) are publicly available through PharmGKB. The aim of this register study was to map the use of drugs in Denmark for drugs having actionable dosing guidelines (AG) i.e., dosing recommendations different from standard dosing for CYP2D6 or CYP2C19 DGI in terms of consumption. Methods: The Danish Register of Medicinal Product Statistics was the source to retrieve consumption in Defined Daily Dose (DDD) i.e., the assumed average maintenance dose per day for a drug used for its main indication in adults and number of users (2017 data). Clinical dosing guidelines were available from the PharmGKB website. Results: Forty-nine drugs have guidelines corresponding to 14.5% of total sales in DDD. Twenty-eight drugs have AG corresponding to 375.2 million DDD. Pantoprazole, lansoprazole, omeprazole, clopidogrel, and metoprolol constituted fifty-eight percent of the consumption in DDD of drugs having AG. The consumption of antidepressant drugs, opioids, and antipsychotic drugs were 157.0 million DDD; with 441,850 users, 48.9 million DDD; with 427,765 users, and 23.7 million DDD; with 128,935 users, respectively. Age distributions of consumption of drugs and drug combinations, e.g., for sertraline redeemed either alone or in combination with metoprolol and tramadol, are presented. Conclusion: This exploratory register study clearly showed that a large fraction of the Danish population, especially the elderly, are exposed to drugs or drug combinations for which there exist AG related to PGx of CYP2D6 or CYP2C19.

Trends in Antiarrhythmic Drug Use in Denmark Over 19 Years

Antiarrhythmic drugs are widely used in the treatment of supraventricular and ventricular arrhythmias. Yet, nationwide long-term utilization trends remain unexplored. We examined 19-year trends in the use of antiarrhythmic drugs in Denmark. Using nationwide prescription data, we obtained information on hospital and primary healthcare use of Class I-V antiarrhythmic drugs from 1999 to 2017. Data was stratified according to sex and age groups. From 1999 to 2017, the total use of antiarrhythmic drugs per 1000 inhabitants/day increased 16% from 36.3 in 1999 to 41.9 in 2017 with peak consumption in 2008 (46.5). In primary healthcare, Class I usage decreased from 0.8 to 0.5 defined daily doses (DDD) per 1000 inhabitants/day, driven by a decreased prescription rate of propafenone (0.4 to 0.1) whereas prescription of flecainide (Class Ic) increased from 0.3 to 0.4 DDD per 1000 inhabitants/day (mainly in men of age 45 to 79 years). Class II usage increased from 15.4 to 33.6 DDD per 1000 inhabitants/day. Class III usage decreased from 2.6 to 1.1 DDD per 1000 inhabitants/day, reflecting reduced prescription rate of sotalol (2.1 to 0.2) whereas amiodarone increased from 0.5 to 0.9 (mainly due to increased prescription among men and women >80 years). Class IV usage declined from 8.6 to 2.8 DDD per 1000 inhabitants/day. Finally, Class V drugs decreased 8.1 to 3.3 DDD per 1000 inhabitants/day. In conclusion, during the past 2 decades considerable changes in prescription rate of antiarrhythmic drugs have occurred, most notably a reduction in sotalol and increased usage of flecainide, Class II drugs, and amiodarone.

Use of topical antipsoriatic drugs in Denmark: a nationwide drug utilization study

The reported real-life use of prescribed topical antipsoriatic drugs is conflicting and based on heterogeneous data sources. To describe the utilization of topical antipsoriatic drugs among patients with psoriasis in Denmark. A drug utilization study was performed based on nationwide Danish health registry data. We identified patients who received a first-time hospital diagnosis of psoriasis and redeemed at least one topical drug prescription in the period 2005-2015 (n=7743). Patients were followed for 3years from the time of diagnosis. Use of topical and systemic antipsoriatic drugs was described, specified by the type of treatment. The total use of topical drugs was divided between corticosteroids with calcipotriol (31%), calcipotriol (6·5%), very potent corticosteroids (24%), potent corticosteroids (30%), moderate corticosteroids (7·2%) and corticosteroids with antimicrobials (1·6%). There was a 19% reduction in the overall use of topical drugs during the study period. Use increased around the time of diagnosis and the majority of patients redeemed more than two packages of topical drugs during the first year after being diagnosed. Regional differences in patients' use of topical drugs varied considerably. The distribution of use of topical drugs was uneven, with a minority of all patients (25%) using 70% of the total amount of topical treatment. There was a 70% increase in the use of methotrexate over the study period. Biologics were used by up to 6%. The study provides further evidence that the use of topical antipsoriatic drugs shows considerable heterogeneity over time and regional practices, and differences between patients.

Utilization and costs of HIV antiretroviral drugs in Europe during the last ten years: Impact of generic antiretroviral drugs on cost reduction

IntroductionSimulation studies showed that generic antiretroviral (ARV) drug utilization could lead to significant cost reduction of HIV treatment in developed world. This study aimed to quantify ARV utilization and costs in European countries between 2006 and 2015. We also assessed the impact of generic ARV drug utilization on cost reduction in real-life. MethodsARV drug utilization in 14 European countries (France, Italy, Germany, Denmark, Netherlands, Norway, Sweden, Finland, Iceland, Croatia, Czech Republic, Estonia, Latvia, and Lithuania) were analysed using defined daily dose (DDD)/1000 inhabitants/year. ARV drug cost was estimated in million euro/year and euro/1000 inhabitants/year. The impact of generics on cost reduction was assessed in three countries: France, Denmark, and Czech Republic, using four parameters: expected savings, observed savings, brand price-reduction savings and overall savings. ResultsBetween 2006 and 2015, median ARV drug utilization increased from 234 DDDs per 1000 inhabitants per year (IQR 124–388) to 385 (229–670). The median cost increased from €3751/1000 inhabitants/year (1109–4681) to €9158 (3269–10,646). Between 2013 and 2015, overall savings of €0.9, €1.6, and €33.7 million were respectively observed in Denmark, Czech Republic, and France. ConclusionOverall savings observed in real-life from generic ARV drugs in Denmark were related to high rate of low-price generic utilization, contrarily to France and Czech Republic where these were more related to brand price-reduction than generic utilization itself.

17-YEAR NATIONWIDE TRENDS IN ANTIHYPERTENSIVE DRUG USE IN DENMARK

Background: Guidelines have changed following new landmark studies on hypertension. Whether use of antihypertensive drugs in clinical practice reflects the temporal changes in guidelines are unknown. We examined long-term trends in the use of antihypertensive drugs in Denmark. Methods: From

Nationwide trends in glucose-lowering drug use, Denmark, 1999-2014.

PurposeThe objective of this study was to examine nationwide population-based time trends in the utilization of all glucose-lowering drugs in Denmark from 1999 to 2014.MethodsBased on nationwide data from the Register of Medicinal Products Statistics, we retrieved sales statistics on glucose-lowering drugs and reported the total number of users and the prevalence of users per 1,000 inhabitants in 1-year intervals for all glucose-lowering drug classes.ResultsThe annual prevalence of glucose-lowering drug users increased more than twofold from 19 per 1,000 inhabitants in 1999 (n=98,362) to 41 per 1,000 in 2014 (n=233,230). Metformin use increased more than sevenfold during the period and was used by 30 of 1,000 inhabitants in 2014, while the prevalence of insulin use increased 1.8-fold to 13 per 1,000 in 2014. After peaking in 2007, use of sulfonylurea halved to 6 per 1,000 in 2014. Newer drug classes including the glucagon-like peptide 1 receptor agonists, the dipeptidylpeptidase-4 inhibitors, and the sodium–glucose cotransporter 2 inhibitors had reached a considerable position by 2014, with 4 per 1,000, 6 per 1,000, and 0.8 per 1,000 inhabitants, respectively; however, the use of glucagon-like peptide 1 receptor agonists and sodium–glucose cotransporter 2 inhibitors in elderly people remained low. Thiazolidinediones decreased to virtually no use (0.03 per 1,000) in 2014.ConclusionThe use of glucose-lowering drugs has doubled during 1999–2014. The pattern of glucose-lowering drug use has changed substantially reflecting the recommendations of metformin as first-line treatment. The newer glucose-lowering drug classes have been well received.

Reducing Prescriptions of Long-Acting Benzodiazepine Drugs in Denmark: A Descriptive Analysis of Nationwide Prescriptions during a 10-Year Period.

Prolonged consumption of benzodiazepine drugs (BZD) and benzodiazepine receptor agonists (zolpidem, zaleplon, zopiclone; altogether Z drugs) is related to potential physiological and psychological dependence along with other adverse effects. This study aimed to analyse the prescribing of long-acting BZD (half-life >10 hr), compared to short-acting BZD in Denmark during a 10-year period. Descriptive analysis of total sales data from the Danish Register of Medicinal Product Statistics, to individuals in the primary healthcare sector, of all BZD and Z drugs in the period of 2003-2013. Prescription data derive from all community and hospital pharmacies in Denmark. The prescribing of long-acting BZD was reduced from 25.8 defined daily doses (DDD)/1000 inhabitants/day in 2003 to 8.8 DDD/1000 inhabitants/day in 2013, a relative reduction of 66%. The prescribing of short-acting BZD was reduced from 26.1 DDD/1000 inhabitants/day in 2003 to 16.4 DDD/1000 inhabitants/day in 2013, a relative reduction of 37%. Prescription data in this study did not include information about indications for initiating treatments. In addition, due to compliance problems, some of the prescribed drugs may not have been consumed according to the prescription. The observed reduction in BZD use was correlated to the introduction of new national guidelines on prescription of addictive drugs, but this study was not designed to detect a causal relationship. The prescribing of long-acting BZD decreased considerably more than the prescribing of short-acting BZD in the 10-year period.

Potential of prescription registries to capture individual-level use of aspirin and other nonsteroidal anti-inflammatory drugs in Denmark: trends in utilization 1999-2012.

BackgroundDue to over-the-counter availability, no consensus exists on whether adequate information on nonsteroidal anti-inflammatory drug (NSAID) use can be obtained from prescription registries.ObjectivesTo examine utilization of aspirin and nonaspirin NSAIDs in Denmark between 1999 and 2012 and to quantify the proportion of total sales that was sold on prescription.MethodBased on nationwide data from the Danish Serum Institute and the Danish National Prescription Registry, we retrieved sales statistics for the Danish primary health care sector to calculate 1-year prevalences of prescription users of aspirin or nonaspirin NSAIDs, and to estimate the corresponding proportions of total sales dispensed on prescription.ResultsBoth low-dose aspirin and nonaspirin NSAIDs were commonly used in the Danish population between 1999 and 2012, particularly among elderly individuals. The 1-year prevalence of prescribed low-dose aspirin increased throughout the study period, notably among men. Nonaspirin NSAID use was frequent in all age groups above 15 years and showed a female preponderance. Overall, the prevalence of prescribed nonaspirin NSAIDs decreased moderately after 2004, but substantial variation according to NSAID subtype was observed; ibuprofen use increased, use of all newer selective cyclooxygenase-2 inhibitors nearly ceased after 2004, diclofenac use decreased by nearly 50% after 2008, and naproxen use remained stable. As of 2012, the prescribed proportion of individual-level NSAID sales was 92% for low-dose aspirin, 66% for ibuprofen, and 100% for all other NSAIDs.ConclusionThe potential for identifying NSAID use from prescription registries in Denmark is high. Low-dose aspirin and nonaspirin NSAID use varied substantially between 1999 and 2012. Notably, use of cyclooxygenase-2 inhibitors nearly ceased, use of diclofenac decreased markedly, and naproxen use remained unaltered.

The Political Pharmacology of Methadone and Heroin in Danish Drug Policy

This article uses the concept of “political pharmacology” to show that drugs are complex and mutable entities, the constitution of which is as much a political (power) issue as it is a technical one. The article analyzes the negotiations and struggles that have been involved in the constitution of methadone and heroin as maintenance drugs in Denmark. Danish drug policy on medical-maintenance treatment was for many years dominated by a medico-administrative technocracy. But from the mid-1990s, this technocracy, and the way it defined maintenance treatment and maintenance drugs, was challenged by drug users and other actors. They were, among other things, dissatisfied with the medical constitution of maintenance drugs as “stabilizing medications” and demanded that the drugs should also be allowed to function as “intoxicating substances.”

Metabolic syndrome and psychiatrists' choice of follow-up interventions in patients treated with atypical antipsychotics in Denmark and Sweden

Introduction: The aim of the present study was to obtain point prevalence estimates of the metabolic syndrome according to the NCEP III criteria in a sample of patients with schizophrenia spectrum disorders treated with atypical antipsychotic drugs in Denmark and Sweden, and to assess the psychiatrists' choice of recommendations for follow-up interventions based on the patients' laboratory results. Method: This was a cross-sectional, observational multi-center study in Denmark and Sweden, in consecutively screened in- and outpatients with schizophrenia spectrum disorders and continuously treated for at least 3 months with atypical antipsychotic drugs. Results: The metabolic syndrome as per medical history was present in 1% of 582 evaluable patients at baseline. After performing laboratory measurements and applying the NCEP III criteria, metabolic syndrome was confirmed in 43% of subjects. The high rate of metabolic syndrome did not elicit much decisive action on the part of the treating psychiatrists; the most frequent action taken was dietary and exercise advice (in 75% of subjects), while in 54% and 19% of subjects a laboratory follow-up and blood pressure follow-up were advised respectively. Change of antipsychotic medication was recommended in only 10% of patients, and in further 11% of patients, no action was taken. Conclusion: Observed metabolic syndrome prevalence rates were at least twice the rates observed in a normal, non-diabetic population. It appears that in this vulnerable population of patients with schizophrenia spectrum disorders, metabolic syndrome remains underdiagnosed and undertreated.

Trends in utilization of antiepileptic drugs in Denmark

To describe utilization of antiepileptic drugs (AEDs) in Denmark during 1993-2002, with special emphasis on oxcarbazepine, and to assess probable indications for AED use. We retrieved prescription data from Odense University Pharmacoepidemiological Database, in Funen County, Denmark (population in 2002: 472,869). Within each calendar year we estimated period prevalence, incidence rate and monotherapy rate. Based on co-medication we defined 'epilepsy' when only AEDs were prescribed, 'pain' with co-prescription of opioids, and 'mood disorder' with co-prescription of antipsychotics or antidepressants. We identified 15,604 AED users. The prevalence of using AED increased from 9.3 (95% CI, 9-9.5) to 12.1 (11.8-12.4)/1000 persons. The incidence rate increased from 1.4 (1.3-1.6) to 1.7 (1.6-1.9)/1000 personyears. The monotherapy rate was 79-82%. AED use for 'epilepsy' declined by 19.7%, whereas the proportion of 'pain' and 'mood disorder' treatment increased by 11.2% and 8.4% respectively. Antiepileptic drug utilization increased during the study period, the increase probably caused by expanding use in areas other than epilepsy.
