Trends in statin utilization and ischemic heart disease mortality in Lithuania and Sweden, 2000-2020.

Aims: To compare statin utilization and ischemic heart disease (IHD) mortality trends in Lithuania and Sweden and to assess correlations between the total utilization of statins and IHD mortality. Methods: An ecological study assessing time trends in statin utilization (DDDs per 1000 inhabitants per day; DDD/TID) and IHD mortality in Lithuania and Sweden between 2000 and 2020. Statin utilization data in Lithuania were wholesale trade data, and Swedish data were drugs dispensed at pharmacies. IHD mortality data were extracted from national databases as rates per 100 000 inhabitants. Associations between statin utilization and IHD mortality in Lithuania and Sweden were examined using Spearman's rank and Pearson's correlation coefficients, respectively. Results: Statin utilization increased from 16.8 to 135.8 DDD/TID in Sweden and from 0.2 to 61.8 DDD/TID in Lithuania between 2000 and 2020. Medium intensity was the most common statin dosage in Lithuania, while Sweden used more high intensity than moderate-intensity statins from 2017. IHD mortality in Lithuania remained high between 2000 and 2020 (from 359.1 to 508.8 deaths per 100 000 population), while it decreased markedly in Sweden (from 226.87 to 88.7 deaths per 100 000 population). IHD mortality and statin utilization were inversely correlated in Sweden (r = -0.993, P < 0.001), while a positive correlation was found in Lithuania (rs = 0.871, P < 0.001). Conclusion: Despite the growing statin utilization in both countries, Lithuania recorded a slight increase in IHD mortality rates unlike the situation in Sweden. This indicates room for improvement in the management of modifiable cardiovascular risk factors in Lithuania including how statins are prescribed and used in clinical practice.

Persistence to statin treatment: A cohort study in Lithuania.

Cardiovascular diseases are the main causes of death, and statins can reduce the risk of major vascular events. Lithuania is among the European countries with the highest cardiovascular mortality despite a rapidly increasing use of statins. Previous reviews have shown the problem of poor patient adherence, but there are limited studies from Eastern European countries. The aim of this study was to evaluate treatment persistence in new users of statins in Lithuania and to investigate factors associated with persistence. Dispensed prescriptions from patients aged >18 years old initiated on statins in 2018-2019 were included, and data were obtained from a national health insurance fund. Persistence was assessed by the proportion of patients who still had statins dispensed 1 year after the first dispensing. Factors associated with persistence were assessed using logistic regression. A total of 104 726 patients (41.3% men) were initiated on statin treatment. Only 41% of them continued statin use 1 year after initiation. Factors associated with higher persistence rate were older age, higher dose of statin, use of other medicines and use of statins as secondary prevention. Low persistence to statin therapy needs to be recognized by healthcare workers, pharmacists and policy makers to address this problem.

Impact of the early COVID-19 pandemic on adult mental health-related dispensed medications, hospitalizations and specialist outpatient visits in Norway and Sweden: Interrupted time series analysis.

AIMS: Norway and Sweden had different early pandemic responses that may have impacted mental health management. The aim was to assess the impact of the early COVID-19 pandemic on mental health-related care. METHODS: We used national registries in Norway and Sweden (1 January 2018-31 December 2020) to define 2 cohorts: (i) general adult population; and (ii) mental health adult population. Interrupted times series regression analyses evaluated step and slope changes compared to prepandemic levels for monthly rates of medications (antidepressants, antipsychotics, anxiolytics, hypnotics/sedatives, lithium, opioid analgesics, psychostimulants), hospitalizations (for anxiety, bipolar, depressive/mood, eating and schizophrenia/delusional disorders) and specialist outpatient visits. RESULTS: In Norway, immediate reductions occurred in the general population for medications (-12% antidepressants to -7% hypnotics/sedatives) except for antipsychotics; and hospitalizations (-33% anxiety disorders to -17% bipolar disorders). Increasing slope change occurred for all medications except psychostimulants (+1.1%/month hypnotics/sedatives to +1.7%/month antidepressants); and hospitalization for anxiety disorders (+5.5%/month), depressive/mood disorders (+1.7%/month) and schizophrenia/delusional disorders (+2%/month). In Sweden, immediate reductions occurred for antidepressants (-7%) and opioids (-10%) and depressive/mood disorder hospitalizations (-11%) only with increasing slope change in psychostimulant prescribing of (0.9%/month). In contrast to Norway, increasing slope changes occurred in specialist outpatient visits for depressive/mood disorders, eating disorders and schizophrenia/delusional disorders (+1.5, +1.9 and +2.3%/month, respectively). Similar changes occurred in the pre-existing mental health cohorts. CONCLUSION: Differences in early COVID-19 policy response may have contributed to differences in adult mental healthcare provision in Norway and Sweden.

Socioeconomic factors associated with poor medication adherence in patients with type 2 diabetes.

PURPOSE: This study aims to determine initiation and persistence for patients with type 2 diabetes receiving their first prescription of an antidiabetic agent and the associations with socioeconomic factors. METHODS: A cohort study including 8515 patients with type 2 diabetes who were prescribed their first antidiabetic medication between 2012 and 2019 in Uppsala, Sweden, was followed during 2 years. Medical records were linked to national registers on dispensed drugs and socioeconomic data. Adherence was assessed based on patients' medication claims within 30 days of prescription (initiation) and continued claims after 24 months (persistence). Multivariable logistic regression was used to determine the associations with the socioeconomic factors age, sex, living status, country of birth, education, occupation, and income. RESULTS: Within 30 days, 92.4% of the patients claimed their first prescription, and 64.0% were still being dispensed the initially prescribed medication after 24 months. Unemployed patients had lower initiation rates, and women had lower persistence rates. Factors associated with both low initiation and persistence were low income, young or old age, birth outside Europe, and being prescribed other diabetes drugs than metformin monotherapy. CONCLUSION: Socioeconomic factors have different impact on the initiation of a new medication and the persistence to treatment in type 2 diabetes. It is important to acknowledge these differences to develop appropriate interventions to improve medication nonadherence.

Machine learning-driven development of a disease risk score for COVID-19 hospitalization and mortality: a Swedish and Norwegian register-based study.

Aims: To develop a disease risk score for COVID-19-related hospitalization and mortality in Sweden and externally validate it in Norway. Method: We employed linked data from the national health registries of Sweden and Norway to conduct our study. We focused on individuals in Sweden with confirmed SARS-CoV-2 infection through RT-PCR testing up to August 2022 as our study cohort. Within this group, we identified hospitalized cases as those who were admitted to the hospital within 14 days of testing positive for SARS-CoV-2 and matched them with five controls from the same cohort who were not hospitalized due to SARS-CoV-2. Additionally, we identified individuals who died within 30 days after being hospitalized for COVID-19. To develop our disease risk scores, we considered various factors, including demographics, infectious, somatic, and mental health conditions, recorded diagnoses, and pharmacological treatments. We also conducted age-specific analyses and assessed model performance through 5-fold cross-validation. Finally, we performed external validation using data from the Norwegian population with COVID-19 up to December 2021. Results: During the study period, a total of 124,560 individuals in Sweden were hospitalized, and 15,877 individuals died within 30 days following COVID-19 hospitalization. Disease risk scores for both hospitalization and mortality demonstrated predictive capabilities with ROC-AUC values of 0.70 and 0.72, respectively, across the entire study period. Notably, these scores exhibited a positive correlation with the likelihood of hospitalization or death. In the external validation using data from the Norwegian COVID-19 population (consisting of 53,744 individuals), the disease risk score predicted hospitalization with an AUC of 0.47 and death with an AUC of 0.74. Conclusion: The disease risk score showed moderately good performance to predict COVID-19-related mortality but performed poorly in predicting hospitalization when externally validated.

A Qualitative Study on Patients' Views on Hypertension and Antihypertensive Medications.

Purpose: Few studies explored what patients initiated on blood pressure medication in primary care think about their disease and their medications. The aim of this study was to gain an understanding of hypertensive patients' views on and experiences of hypertension and the use of antihypertensive medications. Methods: A qualitative study based on open-ended questions from a survey on medication adherence, which captured treated hypertensive patients' perspective on their condition and treatment. Data were collected for 219 patients on antihypertensive medication, ≥ 30 years old, who consulted 25 primary health care centers in Stockholm, Sweden, during 2016. Thematic analysis with both inductive and deductive approach was applied. Results: We identified 21 codes from the data and grouped them under the World Health Organization's five dimensions of adherence: condition-, therapy-, health care team and system-, patient-, and socioeconomic-related factors. The analyses revealed that many patients with hypertension have limited knowledge of their disease, are afraid of drug side effects and experience various issues in primary health care that may negatively impact adherence, including short doctor appointments, prescribing without communication and room for improvement in individualization of therapy and a person-centered approach. Conclusion: Many patients with hypertension have limited understanding of their hypertension and fear of adverse events from their antihypertensive medications. There is also room for improvement in how the patients are managed in primary health care. Interventions should focus on these issues to promote a better blood pressure target achievement.

Hypertension management and drug-related problems. A case report of the 23-year history of Mr. Jonas.

Arterial hypertension is a lifelong disease, which management is recognized as the most effective way to reduce cardiovascular mortality. Even though there is extensive evidence on the benefits of lifestyle modification and antihypertensive treatment, many patients with hypertension do not reach blood pressure targets. This paper aims to review the history of antihypertensive treatment of one patient and identify the drug related problems that occurred over the study period. In this case report, the patient's health record was studied, guidelines checked and a semi-structured interview conducted. Drug related problems were identified and possible pharmacist interventions were introduced. Drug related problems that could have contributed to the lack of hypertension control were adherence, side effects and disease-drug interaction. Identified pharmacists' interventions ranged from managing self-medication, to collaboration with general practitioner to change prescribing, and counselling the patient on medication use, including adherence. Even though the drug related problems were not that serious in the studied case, the patient could have valued from pharmacist intervention.

Stakeholders' perspectives and use of web-based knowledge support for environmental information on pharmaceuticals.

Background: Pharmaceuticals treat and prevent diseases but can pose a risk to organisms, predominantly in aquatic environments. The use of pharmaceuticals is predicted to increase due to, among other factors, a growing and aging population and climate change. Therefore, it is important to develop mitigation strategies to prevent pharmaceutical residues from entering the environment. In Sweden, two public pharmaceutical web-based knowledge supports provide information on the environmental impact of pharmaceuticals. Objective: To explore stakeholder perspectives, use and future opportunities related to two webbased knowledge supports publicizing environmental information on pharmaceuticals. Methods: Stakeholders identified for their experience with the knowledge supports, pharmaceutical policy, and stakeholder collaboration were recruited using purposive and snowball sampling for semi-structured interviews. Interviews were conducted in person or via video calls. Respondents included twenty-one representatives from the pharmaceutical industry, regional and national authorities, academia, and an independent research institute. Interview transcripts were analyzed using content analysis. Results: Respondents valued having environmental information on pharmaceuticals publicly accessible on two well-known pharmaceutical knowledge supports. The knowledge supports have been used in Sweden and internationally. Perceived differences were recognized between the impact and perspectives of the two knowledge supports with a general preference for the Janusinfo knowledge support. The preference was especially identified regarding transparency and the use of the information in clinical practice. Barriers to impact were a lack of resources and decision-making criteria. Respondents believed that the impact and value of the knowledge supports could be improved with more authority involvement. Conclusion: Public knowledge support providing environmental information on pharmaceuticals has been valuable across sectors, especially, among Drug and Therapeutics Committees. We believe the results from this study could be useful for other countries interested in implementing a similar system.

Knowledge support for environmental information on pharmaceuticals: experiences among Swedish Drug and Therapeutics Committees.

BACKGROUND: Two publicly available Swedish knowledge support systems, "Pharmaceuticals and Environment" on Janusinfo.se and Fass.se, provide environmental information on pharmaceuticals. Janusinfo is provided by the public healthcare system in Stockholm and Fass is provided by the pharmaceutical industry. The objectives of this study were to investigate the experiences among Swedish Drug and Therapeutics Committees (DTCs) with using the databases, retrieve development proposals for these, and investigate the DTCs' challenges with working with pharmaceuticals in the environment. METHODS: A cross-sectional survey with 21 questions, both closed and open-ended, was distributed electronically in March 2022 to Sweden's 21 DTCs. Descriptive statistics and inductive categorization were used for the analysis. RESULTS: A total of 132 respondents from 18 regions filled out the survey. The average regional response rate was 42%. The DTCs used the knowledge supports to consider environmental aspects of pharmaceuticals in their formularies and in education. Respondents were more familiar with Janusinfo compared to Fass but appreciated the availability of both. The DTCs especially valued the concrete proposals for certain active pharmaceutical ingredients on Janusinfo. Respondents requested that all medicinal products have environmental information on Fass. Challenges included lack of data, lack of transparency from the pharmaceutical industry and difficulties considering the environmental aspect of pharmaceuticals in their healthcare practice. Respondents wanted more knowledge, clear messages, and legislation to support their work to reduce the negative environmental impact of pharmaceuticals. CONCLUSIONS: This study demonstrates that knowledge supports for environmental information on pharmaceuticals are valuable for the DTCs in Sweden, but the respondents experienced challenges in their work in this field. The study can provide insights to those in other countries interested in considering environmental aspects in their formulary decision-making.

The environmental impact of pharmaceuticals in Italy: Integrating healthcare and eco-toxicological data to assess and potentially mitigate their diffusion to water supplies.

Pharmaceuticals can reach the environment at all stages of their lifecycle and accumulate in the ecosystem, potentially reaching toxic levels for animals and plants. In recent years, efforts have been made to map and control this hazard. Assessing country-specific environmental risks could drive regulatory actions towards eco-friendlier drug utilization and disposal practices. By starting from a list of 25 environmentally hazardous pharmaceuticals developed by Region Stockholm, we integrated eco-toxicological and 2019-2021 Italian drug utilization data to estimate the environmental impact of pharmaceuticals in Italy. We calculated the risk as the ratio between the predicted environmental concentration (PEC) and the predicted no-effect concentration (PNEC). We found a high risk for levonorgestrel, ciprofloxacin, amoxicillin, azithromycin, venlafaxine, sertraline and diclofenac and a moderate risk for ethinyloestradiol, oestradiol and clarithromycin. This analysis can be periodically performed to identify the pharmaceuticals with the highest risk for the environment and ascertain if containment measures should be implemented.

Feasibility and validity of using healthcare databases to conduct cross-national comparative studies of opioid use, its determinants and consequences.

PURPOSE: A cross-national comparative (CNC) study about opioid utilization would allow the identification of strategies to improve pain management and mitigate risk. However, little is known about the accessibility and validity of information in healthcare databases internationally. This study aimed to identify the feasibility of using healthcare databases to conduct a CNC study of opioid utilization and its associated consequences. METHODS: A cross-sectional survey was launched in March 2018, including experts interested in CNC studies comparing opioid utilization by purposeful sampling. An electronic survey was used to collect database characteristics, medicine information, and linkage information of each aggregate-level dataset (AD) and individual patient-level dataset (IPD). RESULTS: Overall, participants from 21 geographical regions reported 18 ADs and 19 IPDs. Information on dispensed medications is available from 17 ADs and 17 IPDs. Of the 16 ADs that include primary care settings, only 9 ADs can obtain information from secondary care settings. Fourteen IPDs included patients' characteristics or could be retrieved from linkage databases. Although most ADs are publicly accessible (n = 13), only five IPDs can be accessed without extra cost. CONCLUSION: Most ADs could be used to report opioid utilization in a primary care setting. IPDs with linkage databases should be applied to identify potential determinants, clinical outcomes, and policy impact. Data access restrictions and governance policies across jurisdictions can be challenging for timely analysis and require further collaboration.

Half a Century of Fragmented Research on Deviations from Advised Therapies: Is This a Good Time to Call for Multidisciplinary Medication Adherence Research Centres of Excellence?

Medication adherence is a key precondition of the effectiveness of evidence-based therapies. However, in real-life settings, non-adherence to medication is still very common. This leads to profound health and economic consequences at both individual and public health levels. The problem of non-adherence has been extensively studied in the last 50 years. Unfortunately, with more than 130,000 scientific papers published on that subject so far, we are still far from finding an ultimate solution. This is, at least partly, due to fragmented and poor-quality research that has been conducted in this field sometimes. To overcome this deadlock, there is a need to stimulate the adoption of best practices in medication adherence-related research in a systematic way. Therefore, herein we propose the establishment of dedicated medication adherence research Centres of Excellence (CoEs). These Centres could not only conduct research but could also create a profound societal impact, directly serving the needs of patients, healthcare providers, systems and economies. Additionally, they could play a role as local advocates for good practices and education. In this paper, we propose some practical steps that might be taken in order to establish such CoEs. We describe two success stories, i.e., Dutch and Polish Medication Adherence Research CoEs. The COST Action "European Network to Advance Best practices & technoLogy on medication adherencE" (ENABLE) aims to develop a detailed definition of the Medication Adherence Research CoE in the form of a list of minimal requirements regarding their objectives, structure and activities. We hope that it will help to create a critical mass and catalyse the setup of regional and national Medication Adherence Research CoEs in the near future. This, in turn, may not only increase the quality of the research but also raise the awareness of non-adherence and promote the adoption of the best medication adherence-enhancing interventions.

Potential Drug-Related Problems in Pediatric Patients-Describing the Use of a Clinical Decision Support System at Pharmacies in Sweden.

The clinical support system Electronic Expert Support (EES) is available at all pharmacies in Sweden to examine electronic prescriptions when dispensing to prevent drug-related problems (DRPs). DRPs are common, and result in patient suffering and substantial costs for society. The aim of this research was to study the use of EES for the pediatric population (ages 0-12 years), by describing what types of alerts are generated for potential DRPs, how they are handled, and how the use of EES has changed over time. Data on the number and categories of EES analyses, alerts, and resolved alerts were provided by the Swedish eHealth Agency. The study shows that the use of EES has increased. The most common type of alert for a potential DRP among pediatric patients was regarding high doses in children (30.3% of all alerts generated). The most common type of alert for a potential DRP that was resolved among pediatrics was therapy duplication (4.6% of the alerts were resolved). The most common reason for closing an alert was dialogue with patient for verification of the treatment (66.3% of all closed alerts). Knowledge of which type of alerts are the most common may contribute to increased prescriber awareness of important potential DRPs.

Physical-mental multimorbidity in a large primary health care population in Stockholm County, Sweden.

BACKGROUND: Multimorbidity of mental and physical disorders may be common. Our objectives were to estimate the prevalence of mental disorders and determine physical-mental multimorbidity relationships adjusted for sex and age within a primary care population in Region Stockholm, Sweden. METHODS: From 2.4 million Region Stockholm inhabitants, we included adult patients with ≥ 1 primary care consultation from 2013 through 2017. We clustered 40 physical diagnoses into 9 categories and grouped mental disorders into mild-moderate (i.e., depression, anxiety, stress disorder, sleep disturbance) or severe (i.e., bipolar disorder, schizophrenia). RESULTS: Of 1 105 065 patients, mean age was 49 years, 56% were females, and nearly one-third had a mental disorder (97% mild-moderate). Adjusted odds ratios (AOR) for mild-moderate and severe mental disorders were highest in patients with alcohol abuse (AOR=3.7, 95% CI 3.6-3.8; AOR=7.2, 95% CI 6.7-7.6, respectively) vs. those with no abuse. Higher odds for either level of mental comorbidity occurred in patients with chronic heart failure (CHF), cerebrovascular disease, Transient ischemic attack (TIA), Chronic obstructive pulmonary disease (COPD), Gastroesophageal reflux disease- irritable bowel syndrome (GERD-IBS), chronic pain, dementia, nicotine dependence, and Parkinson's disease. For mild-moderate mental disorders, AOR in males was highest (1.45) at age 28 and was below 1.0 after age 46; AOR in females was highest (1.30) at age 38 and was below 1.0 after age 38. For severe mental disorders, AOR was below 1.0 after age 58 in males and after age 62 in females. CONCLUSION: Physical-mental multimorbidity was common in primary care patients in Sweden, with the highest odds occurring in those who were female, younger, and/or had an alcohol abuse disorder.

The impact of the war on maintenance of long-term therapies in Ukraine.

Due to the Russian invasion, which started on 24 February 2022, the Ukrainian healthcare system is facing multiple challenges. A great number of healthcare facilities have been destroyed, while availability of other ones is often limited due to a lack of qualified medical staff. Certain services, e.g. cancer therapies, have been seriously disrupted. Moreover, millions of Ukrainians with chronic conditions are also suffering as due to war-related problems with execution of their long-term therapies. Availability of drugs is particularly limited in the occupied regions. According to the national statistics, as of 18 August 2022, about 505 pharmacies were damaged in Eastern Ukraine and 47 completely ruined. Moreover, the invaders have been blocking humanitarian aid provided to these territories by the Ukrainian government or other countries. Fortunately, in the areas controlled by the Government of Ukraine, the acute shortage of medicines, observed at the beginning of the war, has already been eliminated. Nevertheless, not all drugs are now fully available, even in the areas where no military attacks occur. The economic availability of drugs is also profoundly influenced by the significant increase in the cost of medications and the fall in average salaries. The Government of Ukraine is trying to minimise the impact of these war-related challenges by adopting a new legislation. This includes, among others, simplification of procedures for licensing, quality control and import of medicinal products to Ukraine. Other measures involve securing displaced people with the option of benefiting from local healthcare facilities, broadening the scope of the ePrescription system, authorizing primary care doctors to issue prescriptions to refugees, increasing the number of drugs reimbursed for long-term therapies, etc. These solutions, however, cannot balance all the harmful consequences the war in Ukraine brings in terms of maintenance of long-term therapies. Therefore, in order to minimise this negative impact, Ukraine still needs urgent international support in this area.

Effectiveness of COVID-19 Vaccines over 13 Months Covering the Period of the Emergence of the Omicron Variant in the Swedish Population.

BACKGROUND: We estimated real-world vaccine effectiveness (VE) against COVID-19 infection, hospitalization, ICU admission, and death up to 13 months after vaccination. VE before and after the emergence of Omicron was investigated. METHODS: We used registered data from the entire Swedish population above age 12 (n = 9,153,456). Cox regression with time-varying exposure was used to estimate weekly/monthly VE against COVID-19 outcomes from 27 December 2020 to 31 January 2022. The analyses were stratified by age, sex, and vaccine type (BNT162b2, mRNA-1273, and AZD1222). RESULTS: Two vaccine doses offered good long-lasting protection against infection before Omicron (VE were above 85% for all time intervals) but limited protection against Omicron infection (dropped to 43% by week four and no protection by week 14). For severe COVID-19 outcomes, higher VE was observed during the entire follow-up period. Among individuals above age 65, the mRNA vaccines showed better VE against infection than AZD1222 but similar high VE against hospitalization. CONCLUSIONS: Our findings provide strong evidence for long-term maintained protection against severe COVID-19 by the basic two-dose schedule, supporting more efforts to encourage unvaccinated persons to get the basic two doses, and encourage vaccinated persons to get a booster to ensure better population-level protection.

Consumption of antidepressants and economic austerity in Brazil.

OBJECTIVE: To describe consumption of antidepressants in Brazil through dispensing data from pharmacy retail outlets, in between 2011 and 2017, and explore the relationship between consumption patterns and changing economic context during this period. METHODS: A time-series analysis of dispensing data from pharmacy retail outlets was carried out considering 10 commonly used antidepressants. DDDs/1000 inhabitants/year for each drug were calculated for each quarter. Ttime-series graphs were constructed to analyze the volumes of drugs purchasedRelationship between economic context and consumption was assessed using the following indicators: annual percent change in Gross Domestic Product (GDP), public debt (% of GDP), and annual net savings (in billions of Brazilian reais - BRL). RESULTS: Overall consumption of antidepressants increased over the study period despite a sharp fall of -3.55% in annual percent change in GDP, negative net annual savings of -53.568 BRL, and an increase in public debt exceeding 32% of the GDP during the economic crisis of 2015. CONCLUSION: Consumption of antidepressants from pharmacy retail outlets increased even within a context of economic crisis, which may be a reflection of the disease burden in Brazil. Health budget cuts due to the economic crisis may be directing users to out-of-pocket expenses, deepening social inequalities.

Non-persistence to antihypertensive drug therapy in Lithuania.

PURPOSE: Poor persistence to antihypertensive therapy is an important cause of treatment failure. Investigating persistence is especially important in countries with a high cardiovascular mortality, like Lithuania. The aim of this study was to describe the antihypertensive treatment at initiation, to determine the percentage of patients not being persistent with antihypertensive treatment after 1 year and to explore factors associated with non-persistence. METHODS: In this cohort study, data on dispensed prescription medicines from the Lithuanian National Health Insurance Fund (NHIF) were used. All adult patients with a diagnosis of hypertension having first antihypertensive dispensed in 2018 were included. Descriptive statistics was used to determine the number of patients started with monotherapy and combination therapy. Treatment choice by Anatomical Therapeutic Chemical (ATC) and number of active pharmaceutical ingredient (API) was described. Non-persistence was assessed using the anniversary method. Multivariate logistic regression was used to explore factors associated with non-persistence. RESULTS: A total of 72,088 patients were included into the study, 56% started on monotherapy treatment, with 49% being dispensed an angiotensin converting enzyme inhibitor, and 44% started on combination therapy. Overall, 57% of patients were non-persistent after 1 year. Patients' gender and prescriber qualification showed no association with non-persistence. Younger patients, patients from rural area, patients started with monotherapy, and patients with no medication change had higher odds to become non-persistent. CONCLUSIONS: The majority of patients were initiated with treatment following hypertension management guidelines, but it is of concern that over half of the patients were non-persistent to antihypertensive therapy in the first year.
