Dispensed drugs and multiple medications in the Swedish population: an individual-based register study
BACKGROUND Multiple medications is a well-known potential risk factor in terms of patient's health. The aim of the present study was to estimate the prevalence of dispensed drugs and multiple medications in an entire national population, by using individual based data on dispensed drugs. METHODS Analyses of all dispensed out-patient prescriptions in 2006 from the Swedish prescribed drug register. As a cut-off for multiple medications, we applied five or more different drugs dispensed (DP >or= 5) at Swedish pharmacies for a single individual during a 3-month, a 6-month, and a 12-month study period. For comparison, results were also calculated with certain drug groups excluded. RESULTS 6.2 million individuals received at least one dispensed drug (DP >or= 1) during 12 months in 2006 corresponding to a prevalence of 67.4%; 75.6% for females and 59.3% for males. Individuals received on average 4.7 dispensed drugs per individual (median 3, Q1-Q3 2-6); females 5.0 (median 3, Q1-Q3 2-7), males 4.3 (median 3, Q1-Q3 1-6).The prevalence of multiple medications (DP >or= 5) was 24.4% for the entire population. The prevalence increased with age. For elderly 70-79, 80-89, and 90-years, the prevalence of DP >or= 5 was 62.4, 75.1, and 77.7% in the respective age groups. 82.8% of all individuals with DP >or= 1 and 64.9% of all individuals with DP >or= 5 were < 70 years. Multiple medications was more frequent for females (29.6%) than for males (19.2%). For individuals 10 to 39 years, DP >or= 5 was twice as common among females compared to males. Sex hormones and modulators of the genital system excluded, reduced the relative risk (RR) for females vs. males for DP >or= 5 from 1.5 to 1.4. The prevalence of DP >or= 1 increased from 45.1 to 56.2 and 67.4%, respectively, when the study period was 3, 6, and 12 respectively months and the corresponding prevalence of DP >or= 5 was 11.3, 17.2, and 24.4% respectively. CONCLUSION The prevalence of dispensed drugs and multiple medications were extensive in all age groups and were higher for females than for males. Multiple medications should be regarded as a risk in terms of potential drug-drug interactions and adverse drug reactions in all age groups
Physicians' attitudes towards eprescribing: a comparative web survey in Austria and Sweden
Background The eHealth Action Plan required the member states of the European Union (EU) to provide online services such as eprescribing of pharmaceuticals by the end of 2008. So far, implementation activities and efforts of the member states have been uneven. While in Austria pilot projects and feasibility studies have been conducted, Sweden has always been one of the leading countries in the field of eprescribing.
Objective To identify potential success factors for the implementation of eprescribing in Sweden, by comparing the attitudes of Austrian and Swedish physicians.
Method In a web survey, we asked 1824 Austrian and 427 Swedish physicians within primary care and other disciplines to declare to what extent they agreed with ten statements regarding their attitudes towards eprescribing. We deployed the chi-square test for testing the relationship between the country of residence of physicians and their attitudes towards eprescribing.
Results We demonstrated a relationship between the country of residence of physicians and their attitudes towards eprescribing (P<0.001) for all the responses. Of the Swedish physicians, 92% regarded eprescribing as time-saving, 88.1% as being safer and 96.0%as providing a better service for patients. Although less strongly supportive, the attitudes of the Austrian physicians were mainly positive.
Conclusion We found that the major potential success factors for the implementation of eprescribing in Sweden were saving of time for the physician, improved safety and better service for patients. The mainly positive attitudes of the Austrian physicians may enable implementation of eprescribing in due course
Assessment of ePrescription quality: an observational study at three mail-order pharmacies
<p>Abstract</p> <p>Background</p> <p>The introduction of electronic transfer of prescriptions (ETP) or ePrescriptions in ambulatory health care has been suggested to have a positive impact on the prescribing and dispensing processes. Thereby, implying that ePrescribing can improve safety, quality, efficiency, and cost-effectiveness. In December 2007, 68% of all new prescriptions were transferred electronically in Sweden. The aim of the present study was to assess the quality of ePrescriptions by comparing the proportions of ePrescriptions and non-electronic prescriptions necessitating a clarification contact (correction, completion or change) with the prescriber at the time of dispensing.</p> <p>Methods</p> <p>A direct observational study was performed at three Swedish mail-order pharmacies which were known to dispense a large proportion of ePrescriptions (38–75%). Data were gathered on all ePrescriptions dispensed at these pharmacies over a three week period in February 2006. All clarification contacts with prescribers were included in the study and were classified and assessed in comparison with all drug prescriptions dispensed at the same pharmacies over the specified period.</p> <p>Results</p> <p>Of the 31225 prescriptions dispensed during the study period, clarification contacts were made for 2.0% (147/7532) of new ePrescriptions and 1.2% (79/6833) of new non-electronic prescriptions. This represented a relative risk (RR) of 1.7 (95% CI 1.3–2.2) for new ePrescriptions compared to new non-electronic prescriptions. The increased RR was mainly due to 'Dosage and directions for use', which had an RR of 7.6 (95% CI 2.8–20.4) when compared to other clarification contacts. In all, 89.5% of the suggested pharmacist interventions were accepted by the prescriber, 77.7% (192/247) as suggested and an additional 11.7% (29/247) after a modification during contact with the prescriber.</p> <p>Conclusion</p> <p>The increased proportion of prescriptions necessitating a clarification contact for new ePrescriptions compared to new non-electronic prescriptions indicates the need for an increased focus on quality aspects in ePrescribing deployment. ETP technology should be developed towards a two-way communication between the prescriber and the pharmacist with automated checks of missing, inaccurate, or ambiguous information. This would enhance safety and quality for the patient and also improve efficiency and cost-effectiveness within the health care system.</p
Physicians' attitudes towards ePrescribing – evaluation of a Swedish full-scale implementation
<p>Abstract</p> <p>Background</p> <p>The penetration rate of Electronic Health Record (EHR) systems in health care is increasing. However, many different EHR-systems are used with varying ePrescription designs and functionalities. The aim of the present study was to evaluate experienced ePrescribers' attitudes towards ePrescribing for suggesting improvements.</p> <p>Methods</p> <p>Physicians (n = 431) from seven out of the 21 Swedish health care regions, using one of the six most widely implemented EHR-systems with integrated electronic prescribing modules, were recruited from primary care centers and hospital clinics of internal medicine, orthopaedics and surgery. The physicians received a web survey that comprised eight questions on background data and 19 items covering attitudes towards ePrescribing. Forty-two percent (n = 199) of the physicians answered the questionnaire; 90% (n = 180) of the respondents met the inclusion criteria and were included in the final analysis.</p> <p>Results</p> <p>A majority of the respondents regarded their EHR-system easy to use in general (81%), and for the prescribing of drugs (88%). Most respondents believed they were able to provide the patients better service by ePrescribing (92%), and regarded ePrescriptions to be time saving (91%) and to be safer (83%), compared to handwritten prescriptions. Some of the most frequently reported weaknesses were: not clearly displayed price of drugs (43%), complicated drug choice (21%), and the perception that it was possible to handle more than one patient at a time when ePrescribing (13%). Moreover, 62% reported a lack of receipt from the pharmacy after successful transmission of an ePrescription. Although a majority (73%) of the physicians reported that they were always or often checking the ePrescription a last time before transmitting, 25% declared that they were seldom or never doing a last check. The respondents suggested a number of improvements, among others, to simplify the drug choice and the cancellation of ePrescriptions.</p> <p>Conclusion</p> <p>The Swedish physicians in the group studied were generally satisfied with their specific EHR-system and with ePrescribing as such. However, identified weaknesses warrant improvements of the EHR-systems as well as of their implementation in the individual health care organisation.</p

ePrescribing : Studies in Pharmacoinformatics
Det övergripande syftet med den här avhandlingen har varit att, inom området läkemedelsinformatik, studera utvecklingen av elektroniska stöd inom läkemedelsförskrivning; för klinisk praxis, uppföljning och forskning. Under århundraden har det handskrivna receptet varit det sätt, med vilket läkare förmedlat sina läkemedelsordinationer till apotekare, vilket också för patienten blivit en informationskälla för hur läkemedel ska användas för att göra bästa nytta. Nu genomgår receptet en förändring från pappersbaserat till elektroniskt meddelande och att anpassa en traditionell process till en ny elektronisk era innebär både möjligheter och utmaningar. Studierna som ingår i avhandlingen har visat att exponeringen av förskrivna läkemedel i en allmän befolkning har ökat under de senaste tre decennierna. Risken för potentiella interaktioner mellan läkemedel, varmed avses den risk som finns att olika läkemedel kan påverka varandras effekter och biverkningar, har också visat sig öka starkt desto fler läkemedel som används av en individ. Denna ökade samtidiga användning av flera olika läkemedel, så kallad polyfarmaci, medför att det finns en större anledning för förskrivare och farmacevter att uppmärksamma risken för potentiella interaktioner mellan läkemedel. De nyinrättade nationella receptregistren över uthämtad receptförskriven medicin bör användas bland annat för att upptäcka potentiella läkemedelsinteraktioner, såväl i vårdens utövning som inom läkemedelsepidemiologisk forskning. Den svenska läkemedelsförteckningen, som omfattar information om uthämtade receptförskrivna läkemedel för huvuddelen av den svenska befolkningen, bedöms ha en stor klinisk potential. Den enskilde individens historiska information om uthämtade läkemedel är tillgänglig för individen på Internet med hjälp av e-legitimation; även förskrivare och farmacevter på apotek kan ta del av informationen med den enskildes samtycke. Brist på tillgång till enhetliga och säkra autenticeringsmetoder inom hälso- och sjukvården kan dock fördröja tillgången på individuell läkemedelsinformation för förskrivare. I och med att de flesta recepten i Sverige nu skrivs och överförs elektroniskt är det viktigt att kvalitetsmässiga aspekter tas tillvara så att en iakttagen ökad risk för receptförskrivningsfel inte överförs i informationskedjan. Avhandlingens slutsats är att e-förskrivning, med kommunikation och användning av lagrad information om receptexpeditioner, möjliggör att läkemedelsbehandling som process kan följas och studeras på ett helt nyttThe thesis aimed to study the developments, in the area of pharmacoinformatics, of the electronic prescribing and dispensing processes of drugs - in medical praxis, follow-up, and research. For hundreds of years, the written prescription has been the method of choice for physicians to communicate decisions on drug therapy and for pharmacists to dispense medication. Successively the prescription has also become a source of information for the patient about how to use the medication to maximize its benefit. Currently, the medical prescription is at a transitional stage between paper and web, and to adapt a traditional process to the new electronic era offers both opportunities and challenges The studies in the thesis have shown that the exposure of prescribed drugs in the general population has increased considerably over three decades. The risk of receiving potentially interacting drugs was also strongly correlated to the concomitant use of multiple drugs, polypharmacy. The pronounced increase in polypharmacy over time constitutes a growing reason for prescribers and pharmacists to be aware of drug interactions. Still, there were relatively few severe potential drug interactions. Recently established national prescription registers should be evaluated for drug interaction vigilance, both clinically and epidemiologically. The Swedish National Pharmacy Register provides prescription dispensing information for the majority of the population. The medication history in the register may be accessed online to improve drug utilization, by registered individuals, prescribers, and pharmacists in a safe and secure way. Lack of widespread secure digital signatures in healthcare may delay general availability. With a relatively high prevalence of dispensed drugs in the population, the National Pharmacy Register seems justified in evaluating individual medication history. With a majority of prescriptions transferred as ePrescriptions, the detected increased risk for prescription errors warrants quality improvement, if the full potential of ePrescriptions is to be fulfilled. The main conclusion of the studies was that ePrescribing with communication of prescribed drug information, storing and retrieving dispensed drug information, offers new opportunities for clinical and scientifi
Improving interoperability in ePrescribing
Background: The increased application of eServices in health care, in general, and ePrescribing (electronic prescribing) in particular, have brought quality and interoperability to the forefront. The application of standards has been put forward as one important factor in improving interoperability. However, less focus has been placed on other factors, such as stakeholders involvement and the measurement of interoperability. An information system (IS) can be regarded to comprise an instrument for technology-mediated work communication. In this study, interoperability refers to the interoperation in the ePrescribing process, involving people, systems, procedures and organizations. We have focused on the quality of the ePrescription message as one component of the interoperation in the ePrescribing process. Objective: The objective was to analyze how combined efforts in improving interoperability with the introduction of the new national ePrescription format (NEF) have impacted interoperability in the ePrescribing process in Sweden, with the focus on the quality of the ePrescription message. Methods: Consecutive sampling of electronic prescriptions in Sweden before and after the introduction of NEF was undertaken in April 2008 (pre-NEF) and April 2009 (post-NEF). Interoperability problems were identified and classified based on message format specifications and prescription rules. Results: The introduction of NEF improved the interoperability of ePrescriptions substantially. In the pre-NEF sample, a total of 98.6% of the prescriptions had errors. In the post-NEF sample, only 0.9% of the prescriptions had errors. The mean number of errors was fewer for the erroneous prescriptions: 4.8 in pre-NEF compared to 1.0 in post-NEF. Conclusions: We conclude that a systematic comprehensive work on interoperability, covering technical, semantical, professional, judicial and process aspects, involving the stakeholders, resulted in an improved interoperability of ePrescriptions
Acquisition cost of dispensed drugs in individuals with multiple medications--A register-based study in Sweden
Objectives To analyse the acquisition cost of dispensed prescription drugs for individuals with multiple medications in a national population.Methods We collected and analysed individual based data regarding the acquisition cost of dispensed prescription drugs for all individuals with five or more dispensed drugs (DPĂ‚Â >=Ă‚Â 5) in Sweden 2006 (2.2 million).Results Individuals with DPĂ‚Â >=Ă‚Â 5 (24.5% of the population) accounted for 78.8% of the total acquisition cost, and individuals with DPĂ‚Â >=Ă‚Â 10 (8.6% of the population) and DPĂ‚Â >=Ă‚Â 15 (3.0% of the population) accounted for 46.3% and 23.2%, respectively. The average acquisition cost per defined daily doses (DDD) generally decreased with increasing age. The highest average cost per DDD was observed for individuals with DPĂ‚Â >=Ă‚Â 10. The acquisition cost for women with DPĂ‚Â >=Ă‚Â 5 represented 56.0% of the total acquisition cost. Men with DPĂ‚Â >=Ă‚Â 5 represented 44.0% of the total acquisition cost.Conclusions In an entire national population, individuals with multiple medication accounted for four fifths of the total acquisition cost of dispensed drugs. Actions to reduce the number of prescription drugs for the group of patients with a number of different drugs may also result in a substantial reduction of the total acquisition cost.Acquisition cost Dispensed drugs Multiple medications Register
