Background: High blood pressure (BP) or hypertension is defined as a systolic and diastolic pressure over 140/90 mmHg. High blood pressure increases the risk for premature death, and previous research has shown that many patients do not reach targets and that there are differences between primary healthcare centers in the proportion of patient reaching targets. The reasons for these variations, however, are unknown. Aim: To investigate variations in blood pressure target achievement between primary care centers in Stockholm county and how different factors such as practice size, ownership, socioeconomic and antihypertensive drug treatment can influence this diversity. Method(s): This study was designed as a cross-sectional register study with a descriptive quantitative perspective. Data was collected from three sources: National Primary Care Quality register, Care Need Index for healthcare in Stockholm region and Stockholm County Council data warehouse VAL. The study included 179 out of all 227 primary care centers in the region. The proportion of all patients with hypertension reaching targets was assessed each year during 2019-2021, and correlations studied for potential predictors. Results: there was a variation between primary care centers in target blood pressure fulfillment, ranging from 22-66% during 2021, 23-63% during 2020 and 33-66% during 2019, respectively. There was no overall difference between public and private centers in the proportion of patients reaching targets, but a larger practice variation among private centers. No correlation was found between the other studied factors and target blood pressure fulfillment during 2021. Conclusion: There was a variation between primary care centers in the proportion of patients reaching blood pressure targets. Different practices may change ranking between years and other factors than practice size, ownership and socioeconomic appears to explain the variation.

Introduction Human immunodeficiency virus (HIV) is a double stranded RNA retrovirus. According to the World Health Organization more than 30 million individuals were estimated to have HIV by the end of 2020, about 60% of which are in the African region. Pre-treatment drug resistance (PDR) can be defined as the resistant virus strains transmitted at the time of infection or acquired during previous exposure to ARV. This study asses the effect of drivers in PDR. Method: This study was conducted with data extracted from published, publicly available data bases and reports by international organizations. The main sources were United Nation data bases and published reports from World Health Organization.  Inferential statistics were used to assess the PDR to anti-retroviral drugs. A linear regression model was used to investigate the association between PDR and previous exposure to anti-retrovirals and anti-retroviral therapy, pre-exposure prophylaxis, national health expenditure, human development index, and drug stock-out for different classes of anti-retroviral drugs.   Results: The result indicated that NNRTI drug resistance was most common, and seven out of 29 countries had PDR to all four drug classes. The human development index was positively associated with INSTI and PI PDR (p<0.05), while NNRTI and NRTI were mainly positively associated with previous exposure to anti-retrovirals. Conclusion: This study assessed the impact of socio-economics determinants (human development index and national health expenditure), drug logistic determinants (stock-out), and patients’ determinants (adherence and previous exposure to any kind of anti-retrovirals) on PDR. For expensive drug classes (PI and INSTI) the resistance was positively associated with human development index. Previous exposure to anti-retrovirals was associated with increased resistance in NNRTI and NRTI.

Akut hjärtsvikt definieras som en debut eller försämring av hjärtsvikt. Hjärtsvikt är ett allvarligt tillstånd där hjärtat inte upprätthåller adekvat hjärtminutvolym för att möta kroppens metaboliska behov vilket leder till trötthet och försämrad livskvalitet. Symtom som relaterar till systemisk vätskeansamling är vanliga vid akut hjärtsvikt. Vätskeansamling och hypoperfusion ökar morbiditet och mortalitet. Patienter med akut hjärtsvikt behöver således snabba och effektiva behandlingar, men också långtidsbehandling efter utskrivning. Avsvällande/vattendrivande behandling är hörnstenen i den terapeutiska behandlingen och loopdiuretika anses som det mest effektiva och snabbverkande läkemedlet. I dagsläget är empagliflozin ett rekommenderat läkemedel för behandling av kronisk hjärtsvikt med nedsatt ejektionsfraktion, då empagliflozins diuretiska egenskap kan stärka effekten av loopdiuretika.   Syftet med detta examensarbete var att beskriva effekter hos empagliflozin vid behandling av akut hjärtsvikt som en litteraturstudie. En sökning av randomiserade kliniska prövningar gjordes i PubMed där nio artiklar valdes ut för att ingå i detta examenarbete. Resultatet av de granskade artiklarna visade att empagliflozin som tilläggsbehandling till loopdiuretika ökade urinutsöndring hos patienterna. Resultatet visade också en statistiskt signifikant minskning av NT-proBNP i studierna vars behandlingstid var 5, 7, 15 och 30 dagar jämfört med placebo. Vidare minskade empagliflozin också plasmavolymen och mängden urinsyran i plasman. Två av studierna rapporterade en statistiskt signifikant ökning i andel röda blodkroppar i behandlingsgruppen. Insättning av empagliflozin, hos kliniskt stabila sjukhusvårdade patienterna i studien EMPULSE, gav en statistiskt signifikant klinisk nytta definierat som ett hierarkiskt kompositmått av död oavsett orsak, antal hjärtsviktsepisoder, tid till första hjärtsviktsepisod och klinisk meningsfull förbättring i KCCQ-TSS med vinstratio 1,36. Vidare gav empagliflozin en positiv effekt på viktminskning, ökad diuretisk respons, ödemlindring och ökad livskvalitet under 90 dagars behandling. Hos patienter som fick empagliflozin sänktes eGFR något till en början men återställdes senare. Det fanns dock inte någon statistiskt signifikant skillnad i eGFR mellan grupperna. En av studierna visade på en signifikant minskning av biomarkörer hos patienter som fick empagliflozin vilket gav en njurfunktionsskyddande effekt mot akut njurskada.  Slutsatsen var att empagliflozin gav gynnsamma effekter såsom till exempel avsvällande/vätskedrivande effekt och klinisk fördel hos patienter med såväl akut de novo som med dekompenserad kronisk hjärtsvikt vilket betydde att läkemedlet var både säkert och effektivt. I framtiden behöver effekterna dock styrkas genom ytterligare studier med större antal deltagare och under längre behandlingstid efter sjukhusutskrivning.

Background: Medications are used to treat, cure, or relieve symptoms of diseases, but there is a risk with the use of medications. Drug-related-problems are known to increase morbidity and mortality. Incorrect medical list and discrepancies in these lists can lead to drug-related problems as side effects, hospitalization, non-compliance, drug interactions and overtreated or undertreated patients. Discrepancies can be for example: more prescriptions than necessary, outdated prescriptions, i.e., medicines that will not be used, prescriptions with incorrect dosing and missing prescriptions i.e., medicines used by patients that cannot be seen in the medication list. Purpose:  The aim of this study was to investigate discrepancies in the Swedish prescription list "My saved prescriptions at the pharmacy". The secondary aim was to investigate how common it is to use this prescription list or the dosage label on the medicine packaging to know which medicines to use and which dosage. Methods: The data collection was performed by four pharmacy students at seven pharmacies in Sweden over a period of three weeks during Jan-Feb. 2021 where the prescription list was investigated together with patients to identify any discrepancies. The study included patients who was over 18 years old, spoke Swedish, had three or more prescribed drugs, and agreed to participate.  Results A total of 215 patients were interviewed, where 61% had one or more discrepancies in their medication list. A total of 1717 prescriptions were analyzed, of which 10% were double prescriptions (n = 167), 8% outdated prescriptions (n = 141) and 3% prescriptions with the wrong dosage (n = 42). When analyzing the primary sources of information used by patients to know which medicine to use, the printout of the list "my saved prescriptions at the pharmacy” dominated (n = 72).  Most used information source to know drug dosage was the dosage label on the medicine packaging (n = 112). Conclusions: It is important to have an updated and correct information in the medication list, to prevent drug-related-problems caused by discrepancies. It becomes even more important when we see that the medication list "My saved prescriptions at the pharmacy" and dosage label (containing the same information in the medication list), are the most used primary sources by patients to know which drug to use and in what dosage. Finally, results show a relationship between the number of prescribed drugs and the number of discrepancies that occur, and therefore we see more discrepancies in elderly patients who are usually ill and are being treated for several diseases.  There are opportunities for further research to study e.g., which drug-related-problems are caused by discrepancies in the medication list as well as the degree of danger in these problems. / Användning av läkemedel som avses behandla, lindra eller bota sjukdomar kan i vissa fall utgöra en risk för patientens hälsa. Läkemedelsrelaterade problem p.g.a. felmedicinering står för en stor andel av morbiditeten och mortaliteten bland patienter. En bidragande orsak är ofullständig information i patientens läkemedelslista.   Syftet med studien var att undersöka antalet avvikelser som förekommer i receptlistan ”Mina sparade recept på apoteket”. Studiens sekundära syfte var att undersöka vilka informationskällor som användes av patienter för att veta vilka läkemedel som ska adminstreras och i vilken dos dosering.  Studiens metod var att intervjua patienter som kom till apoteket för att hämta ut läkemedel till sig själva och uppfyllde inklusionskriterierna för att delta i studien. Studien utfördes av fyra farmaceutstudenter på sju olika apotek i fyra olika städer i Sverige som tillsammans med patienter gick igenom receptlistan för att identifiera avvikelser.  Resultatet blev totalt 1717 recept som studerades varav 21% hade avvikelser. Av recepten var 10% dubbla recept (n = 167), 8% inaktuella recept (n = 141) och 3% recept med fel dosering (n = 42). Vid analys av primära informationskällor som används dominerade utskrift av listan ”Mina sparade recept på apoteket” (n = 72) resp. doseringsetiketten på läkemedelsförpackningen (n = 112).  Resultaten visade även ett samband mellan ökade antal läkemedel och antalet avvikelser.  Avvikelser i läkemedelslistan Mina sparade recept är vanligt förekommande därmed är listan inte alltid aktuell. Det är vanligt att denna lista och doseringsetikett på läkemedels-förpackningar används som primära källor av patienter under deras behandlingstid vilket kan innebära en risk för läkemedelsrelaterade problem. En gemensam nationell läkemedelslista är en möjlig lösning till att förebygga läkemedelsrelaterade problem orskade av infromationsbrist i läkemedelslistor. Det är dock nödvändigt med läkemedelsgenomgångar för att bibehålla uppdateringen av listan.

Background: Type II diabetes is a common disease worldwide and several drug treatments are available. Some of the more recently approved drugs are DPP4-inhibitors, GLP analogues and SGLT2-inhibitors. Most of the Type II diabetes drugs (T2DMD) are prescribed by primary care physicians. To ensure rational drug use it is important to follow up prescribing patterns to design strategies and interventions that can improve drug treatment, since consequences of inappropriate drug use might be poor health outcomes and increased health costs. Aim: To study differences in the prescribing pattern of T2DMD among primary healthcare centres (PHC) at a macro level in Region Uppsala. Method: A cross-sectional study based on data collected from Region Uppsala’s data register. Data consisted of individuals over 25 years of age with at least one prescription of a diabetes drug from the Anatomic Therapeutic Chemical (ATC) group A10 prescribed within the period of January 2018 to June 2020. Results: There is a moderate difference in the prescribing patterns of T2DMD among different PHCs in Region Uppsala. Overall, a larger proportion of oral antidiabetic drugs (OAD) were prescribed compared to Insulins. Most PHC prescribed a larger proportion of long acting insulins than other Insulins. Among OAD, a larger proportion of Biguanide derivative where prescribed. DPP-4 inhibitors, Sulphonylureas and SGLT2-inhibitors were prescribed to almost the same extent. Conclusion: Overall, there is a minor difference in the prescribing patterns of T2DMD among different PHCs in Region Uppsala during the study period. Lately, prescribing of DPP4-inhibitors, SGLT2-inhibitors and long acting insulins have increased. / I detta fördjupningsprojekt studerades förskrivningsmönstren av typ II diabetesläkemedel i Region Uppsala. Studieresultaten vissa skillnader i hur olika vårdcentraler i Region Uppsala förskriver typ II diabetesläkemedel. Från början var hypotesen att icke-insuliner förskrivs i större utsträckning än insuliner. Vilket visade sig stämma överens med resultaten. I studien jämförs också skillnaden mellan förskrivning av icke-insuliner som funnits längre på marknaden och de nyligen godkända (DPP4-hämmare och SGLT2-inhibitorer). Resultaten visar en tydlig ökning i förskrivning av de nya läkemedlen under studieperioden. En anledning till detta kan vara läkemedels positiva farmakologiska effekter. I studien jämförs också skillnaden i förskrivningen av de olika insuliner i Region Uppsala. Resultaten visar att långverkande insuliner förskrivs i större utsträckning i jämförelse med andra insuliner, vilket är inte enligt rekommendationslistan för förskrivning av typ II diabetesläkemedel Studieresultaten kan användas för att fortsätta följa upp och förbättra kvalitén på diabetesvården i Region Uppsala. Ytterligare studier skulle till exempel kunna utgå ifrån hela populationen med en typ 2 diabetesdiagnos för att studera utfall även för andra interventioner än läkemedel. Dessutom behövs fortfarande kunskap om det är kostnadseffektiv att fler nya typ 2 diabetesläkemedel används. Studien ger kunskap om förskrivningen av typ II diabetesläkemedel i Region Uppsala. Studien kan användas som grund för dialog om förskrivningen av typ II diabetesläkemedel i regionen, så att denna optimeras och fler individer får adekvat behandling. Detta arbete är viktigt eftersom typ II diabetes är en mycket vanlig sjukdom där prevalensen ökar.  Denna studie är en tvärsnittsstudie baserat på sekundärdata från Region Uppsalas elektroniska medicinalt register och primärdata från två enkäter skickade till sjuksköterskor och läkare som jobbar på vårdcentraler med patienter med diabetes. Studien inkluderar data från de 26 offentliga vårdcentraler som hör till förvaltningen Nära, Vård och Hälsa i region Uppsala. Förskrivningsdata baseras på recept för ett diabetesläkemedel från Anatomic Therapeutic Chemical (ATC) gruppen A10, förskrivet mellan januari 2018-juni 2020.

Background and Objective: Comorbidity and especially cardiovascular diseases are common among patients with chronic obstructive pulmonary disease (COPD). The primary purpose of this study was to identify drugs for the treatment of cardiovascular diseases in COPD patients. The secondary purpose was to analyze whether the use of cardiovascular drugs differs between patients with mild and severe COPD symptoms.     Method: The study was a retrospective cross-sectional study of 421 COPD patients whose drug lists were analyzed and cardiovascular drugs were identified. These drugs were then divided into eight drug groups, based on the drug's ATC (Anatomic Therapeutic Chemical classification system) codes. Only patients with reported cardiovascular diseases were included in the analysis. Patients with mild and severe COPD symptoms were identified. Thereafter, the patients were divided into two groups based on the COPD symptoms. Chi-squared test was performed to see if the use of cardiovascular drugs differs between patients with mild and severe COPD symptoms.  Setting: Primary and secondary care patients with COPD in Gävle and Dalarna.  Main outcome measures: Identify and analyze the use of cardiovascular drugs in COPD patients with mild and severe symptoms.  Results: The results of the survey showed that cardiovascular drugs were used by 274 (65%) of the COPD patients. Among them, 66 % with severe COPD symptoms and 34 % with mild symptoms. The use of the eight cardiovascular drug groups were similar between patients with mild and severe COPD symptoms. There wasn’t any statistically significant difference in the use of cardiovascular drugs between patients with mild and severe COPD symptoms (p= 0,893).   Conclusions: There wasn’t any difference in the use of cardiovascular drugs among patients with mild and severe COPD symptoms. However, this result needs to be substantiated with a follow-up study with a larger study population and longer study time to be generalizable.

Background: Pressurized metered dose inhalers (pMDI) use propellants for pulmonary drug delivery. The propellants used in pMDI:s are strong greenhouse gases. The Powder dose inhaler (PDI) doesn’t use any propellants and contributes less to the carbon footprint. Aim: The purpose of this project is to present data on inhaler use in the Uppsala County Council in Sweden. This project aims to answer questions regarding pressurized metered dose inhalers (pMDI) carbon footprint, how prescriptions of inhaler types with lower carbon footprint compare with pMDI and how the Uppsala County Council compares with other county councils in Sweden. Methods: This cross-sectional study uses prescription data for collected inhalers in Uppsala County Council and similar county councils in Sweden. Calculations of carbon footprint of the propellants in pMDI:s and for the lifecycle of pMDI and PDI. Results: The study showed that the climate load from the greenhouse gases norflurane and apaflurane in pMDIs are 981 477kg CO2e in Uppsala County Council year 2020. Of all the county councils studied, the county council with the highest percentage of pMDIs use was Stockholm County Council, the Uppsala County Council was close second.  Conclusion: Uppsala County Council might need to review if there is a way to lower the amount of pMDI prescriptions to reduce its carbon footprint deviating from the rest of County Councils in Sweden. This project ties into Uppsala County Council goal of reducing the climate impact of medical anesthesia greenhouse gases with 10% by 2022 from 2018.

In order for a medication treatment to be considered successful, several roles and functions along the pharmacological treatment chain must function and cooperate effectively. The chain can most easily be described as five transitions; diagnosis, prescription treatment, dispensing, drug use and finally results and follow-up. Unfortunately, there are many problems and inefficiencies in the pharmacological drug chain. Unfortunately, those who study medication errors and their solutions have focused on individual parts of the pharmacological treatment system. However, for this reason, this study aims to develop a general framework for system analysis of inefficiencies along the pharmacological treatment chain. Due to the size of the problem, this project focused on medication adherence. Adherence can be defined as to what extent the patient follows the medication treatment plan. Adherence has many known problems and difficulties, among other things, it has major financial consequences. It can also be difficult to measure compliance, and there is no recognized perfect method. A system dynamic model is a theoretical image of a real system or object, which is a model used to understand the nonlinear behavior of complex systems. These models are useful when considering interventions and their effects when there are complex relationships. The project started with a literature study, and then went into data collection. Here, a search design and refinements were designed to find relevant articles. Once the articles were selected, the data was compiled from the articles and the analysis began. Here, factors and effects on adherence were identified as well as other interesting information from the articles. When the information was compiled and analyzed, the system dynamic model was created. The model was then sent via email to experts in the field to validation and revise the model. During the data collection, 23 relevant articles were found, compiled into 38 factors associated with compliance. In addition to these factors, 8 were excluded because they were too disease-specific or too ambiguous in their effect of adherence. The various articles studied many different chronic diseases, but hypertension was the most common. How adherence was measured in the articles also varied greatly, however, some form of self-report or questionnaire was most common method used. Three out of seven experts responded to the sent-out model and provided valuable comments. Although these are not sufficient to validate the model, their views showed that a validation can be designed in this way. The model would have to be sent to a larger set of experts and stakeholders, but because these experts are recognized in their fields, it gave weight to the results even though they were few reviewers. With the support of the literature and the experts’ statement, it was concluded that this model provides a good foundation and structure to continue to build upon. In addition, the model has proven to have many key relationships and cornerstones with important and relevant factors. It is also concluded that it is possible to translate the model into quantitative patterns, which is based on the fact that the factor itself can be translated quantitatively. Overall, it is also finally concluded that the model created in this project could be of great use in future projects when working towards a framework for system analysis of inefficiencies along the pharmacological treatment chain.

Bakgrund: Globalt drabbas 300 miljoner av depression och sjukdomen kan idag behandlas med både antidepressiva läkemedel och psykoterapi. Depression diagnosticeras utifrån klassificeringssystemen ICD-10 och DSM-5 och självskattats utifrån MADRS-skala. Sjukdomen kan delas in i följande svårighetsgrader: lätt/lindrig depression, medelsvår/måttlig depression och svår/djup depression. Vid val av antidepressiva läkemedel är det viktigt att ta hänsyn till svårighetsgrad, biverkningar och interaktioner.  Syfte: Syftet med denna studie är att kartlägga läkemedelslistor framtagna av Sveriges olika läkemedelskommittéer och beskriva val av läkemedelsbehandling vid depression för vuxna och äldre.  Metod: En dokumentanalys utfördes som lämpar sig till att kunna jämföra aktuell offentlig information. Datainsamlingen utfördes hösten 2022 med hjälp av Sveriges 21 olika regioners behandlingsrekommendationer för vuxna och äldre. En egen bedömningsskala med maximalt tre poäng utfördes för att lyckas bedöma regionernas läkemedelsrekommendationer.  Resultat: För vuxna rekommenderar 19 regioner vid lindrig-medelsvår depression sertralin, vid medelsvår-svår rekommenderar 13 regioner venlafaxin och vid svår rekommenderar sex regioner TCA där amitriptylin/klomipramin är mest förekomna. För äldre rekommenderar 13 regioner sertralin/mirtazapin/escitalopram vid lindrig-medelsvår depression, vid medelsvår-svår rekommenderar 13 regioner duloxetin/venlafaxin och vid svår rekommenderar två regioner duloxetin. Enligt den egna bedömningsskalan uppnås varierande antal poäng där totalt sju regioner uppnår maximal poäng.  Slutsats: SSRI var den vanligaste preparatgruppen som rekommenderades av regionerna vid medelsvår depression hos både vuxna- och äldre. Vid svår depression var den vanligaste preparatgruppen SNRI för äldre och TCA för vuxna. Enligt den egna bedömningsskalan var Läkemedelverkets och Socialstyrelsens rekommendationer mest vanligt förekomna källorna hos regionerna. / Background: Globally, 300 millions of people suffer from depression and the disease can today be treated with both antidepressants and psychotherapy. Depression is diagnosed from the classification system ICD-10 and DSM-5 and is self-assessed based on the MADRS-scale. The disease can be divided into the following difficulty level: light/mild depression, medium/moderate depression, and severe/deep depression. It is very important to consider difficulty level, side effects and interactions when choosing an antidepressant.  Aim: The aim of this study is to identify drug lists produced by Sweden’s different pharmaceutical committees and describe the choice of drug treatment for depression for adults and the elderly.  Materials and methods: A document analysis was performed which is suitable to be able to compare public information. The collection of data was performed autumn 2022 with the help of Sweden’s 21 different regions treatment recommendations for adults and the elderly. An own assessment scale was accomplished to judge the regions drug treatment recommendations. Results: For the adults, 19 regions primarily recommend sertraline for mild-moderate depression, for moderate-deep depression 13 regions recommend venlafaxine and for deep depression six regions recommend TCA where amitriptyline/clomipramine are most common. For the elderly, 13 regions primarily recommend sertraline/mirtazapine/escitalopram for mild-moderate depression, for moderate-deep depression 13 regions recommend duloxetine/venlafaxin and for deep depression two regions recommend duloxetine. According to the own assessment scale a varying number of points were achieved, were a total of seven regions achieved maximum points.  Conclusions: SSRIs were the most common drug group recommended by the regions for moderate depression for both adults and the elderly. In deep depression the most common drug group was SNRIs for the elderly and TCAs for adults. According to the own assessment scale the Swedish- Medicines Agency and Social Welfare Board are most common sources in the regions.

Introduction: Alzheimer's disease is a neurodegenerative disease that initially manifests itself primarily as impaired short-term memory and impaired language ability. The course of the disease is mainly due to an atrophy in the brain that can be attributed to the protein amyloid B and tau. Monoclonal antibodies that target Alzheimer's disease often have a high rate of cerebral edema, where proteinaceous fluid leaks into the extracellular space of the brain and creates edema. Some of the most common symptoms for amyloid-related imaging abnormalities (ARIA-E) are headache, dizziness, and blurred vision. In a few cases, patients with ARIA-E need to be hospitalized for observation, but most show a decline in ARIA-E within one to two months. Objective: To investigate the frequency of ARIA-E in clinical studies of monoclonal antibodies to patients with Alzhiemer's disease and to investigate the role of the ApoE4 allele in the development of ARIA-E. Method: Literature review of five RCT studies based on four different monoclonal antibodies. PubMed was used to search for the RCT-studies. Results: ARIA-E varies between different types of antibodies. ARIA-E usually occurs early in treatment when the degree of amyloid b is highest in the brain. Most cases are asymptomatic and treatment resumes within 1-2 months. Conclusion: Aria-E frequency correlates strongly with dose strength as well as APOE4 -status and most of the incidences are asymptomatic. With the right titration and individually selected drugs as well as individual dosages a safe care can be established for patients with Alzheimer's disease. If treatment is initiated at an early stage, the risk of side effects is reduced and more neurons can be saved from atrophy. The combination of several different types of medicine will further reduce the risk of ARIA-E.
