Short-term learning effect of ChatGPT on pharmacy students' learning.

Introduction: Students in pharmacy are positive towards integrating artificial intelligence and ChatGPT into their practice. The aim of this study was to investigate the direct short-term learning effect of using Chat GPT by pharmacy students. Methods: This was an experimental randomized study. Students were allocated into two groups; the intervention group (n = 15) used all study tools and ChatGPT, while the control group (n = 16) used all study tools, except ChatGPT. Differences between groups was measured by how well they performed on a knowledge test before and after a short study period. Results: No significant difference was found between the intervention and control groups in level of competence in the pretest score (p = 0.28). There was also no significant effect of using ChatGPT, with a mean adjusted difference of 0.5 points on a 12-point scale. However there was a trend towards a higher proportion of ChatGPT participants having a large (at least four point) increase in score (4 out of 15) vs control group (1 out of 16). Conclusion: There is a potential for positive effects of ChatGPT on learning outcomes in pharmacy students, however the current study was underpowered to measure a statistically significant effect of ChatGPT on short term learning.

Health-related quality of life among older adults following acute hospitalization: longitudinal analysis of a randomized controlled trial.

PURPOSE: To describe the longitudinal change of health-related quality of life (HRQoL) over 12 months from acute hospitalization in older adults ≥ 70 years (IMMENSE study), and associated factors, to investigate how a medication optimization intervention influenced this change. METHODS: The EQ-5D-3L was used at discharge and 1, 6 and 12 months after discharge during a randomized controlled trial including 285 participants. Multilevel logistic (EQ-5D-3L dimensions) and mixed model regression (EQ-5D-3L index scores, EQ-VAS) were used to explore the longitudinal change with/without the intervention, and associations with medications, comorbidities, and socioeconomic variables. Subgroup analyses were performed for non-long and long stayers with hospitalizations < or ≥ 14 days. RESULTS: EQ-5D-3L index scores significantly declined after 12 months (ß -0.06 [95% confidence interval (CI:) -0.10--0.02], p = 0.003). Non-long stayers showed significant improvement 1 month from discharge (ß 0.05 [0.00-0.09], p = 0.040). The number of medications and receiving home-care services were the main factors associated with reduced HRQoL. Being home-dwelling was the main factor associated with higher HRQoL. Non-long stayers of the intervention group reported significantly higher EQ-VAS than the control group (ß 4.02 [0.11-7.93], p = 0.044). CONCLUSION: We observed no significant difference in the longitudinal change in HRQoL between the two IMMENSE study groups over 12 months after hospitalization. However, the non-long stayer subgroup analysis indicates that the intervention may have had a long-term effect on HRQoL in some of intervention patients. The number of medications and the ability to live and care for oneself should be taken into consideration when planning future patient care and health-care services. TRIAL REGISTRATION: The trial was registered in clinicaltrials.gov on 28/06/2016 before enrolment started (NCT02816086).

Barriers and facilitators of pharmacists' integration in a multidisciplinary home care team: a qualitative interview study based on the normalization process theory.

BACKGROUND: There is a growing recognition of multidisciplinary practices as the most rational approach to providing better and more efficient healthcare services. Pharmacists are increasingly integrated into primary care teams, but there is no universal approach to implementing pharmacist services across healthcare settings. In Norway, most pharmacists work in pharmacies, with very few employed outside this traditional setting. The home care workforce is primarily made up of nurses, assistant nurses, and healthcare assistants. General practitioners (GPs) are not based in the same location as home care staff. This study utilized the Normalization Process Theory (NPT) to conduct a process evaluation of the integration of pharmacists in a Norwegian home care setting. Our aim was to identify barriers and facilitators to optimal utilization of pharmacist services within a multidisciplinary team. METHODS: Semi-structured interviews (n = 9) were conducted with home care unit leaders, ward managers, registered nurses, and pharmacists in Norway, in November 2022-February 2023. Constructs from the NPT were applied to qualitative data. RESULTS: Findings from this study pertain to the four constructs of the NPT. Healthcare professionals struggled to conceptualize the pharmacists' competencies and there were no collectively agreed-upon objectives of the intervention. Consequently, some participants questioned the necessity of pharmacist integration. Further, participants reported conflicting preferences regarding how to best utilize medication-optimizing services in everyday work. A lack of stakeholder empowerment was reported across all participants. Moreover, home care unit leaders and managers reported being uninformed of their roles and responsibilities related to the implementation process. However, the presence of pharmacists and their services were well received in the setting. Moreover, participants reported that pharmacists' contributions positively impacted the multidisciplinary practice. CONCLUSION: Introducing new work methods into clinical practice is a complex task that demands expertise in implementation. Using the NTP model helped pinpoint factors that affect how pharmacists' skills are utilized in a home care setting. Insights from this study can inform the development of tailored implementation strategies to improve pharmacist integration in a multidisciplinary team.

General practitioners' role in safeguarding patients with dementia in their use of dietary supplements. A qualitative study.

OBJECTIVE: The use of dietary supplements (DS) may cause harm through direct and indirect effects. Patients with dementia may be particularly vulnerable. This study aims to explore general practitioners' (GPs') experiences with DS use by these patients, the GPs perceived responsibilities, obstacles in taking on this responsibility, their attitudes toward DS, and suggestions for improvements to safeguard the use of DS in this patient group. DESIGN: Qualitative individual interview study conducted February - December 2019. Data were analysed using systematic text condensation. SETTING: Primary healthcare clinics in Norway. SUBJECTS: Fourteen Norwegian GPs. FINDINGS: None of the informants were dismissive of patients using DS. They were aware of the possible direct risks and had observed them in patients. Most GPs showed little awareness of potential indirect risks to patients with dementia who use DS. They acknowledged the need for caretaking of these patients. Although there were differences in practice styles, most of the GPs wished to help their patients safeguarding DS use but found it difficult due to the lack of quality assurance of product information. Furthermore, there were no effective ways for the GPs to document DS use in the patients' records. Several suggestions for improvement were given by the GPs, such as increased attention from GPs, inclusion of DS in the prescription software, and stricter regulatory systems for DS from the authorities. CONCLUSION: The GPs had initially little awareness of this safety risk, but there were differences in practice style and attitudes towards DS. The GPs did not perceive themselves as main responsible for safe use of DS in patient with dementia. The most important reason to disclaim responsibility was lack of information about the products. One suggestion for improvement was better integration of DS in patients' medical record.

Currently, little is known about general practitioners (GPs) caretaking of patients with dementia who use dietary supplements (DS). Our study showed that:The GPs in this study showed little awareness of the potential safety risk that DS use may represent for patients with dementia.Several obstacles in the treatment setting and in the regulation of DS make it difficult for the GPs to assume full responsibility for patients with dementia who use DS.Lack of evidence about DS safety and effect adds to professional uncertainty and may cause frustration or reluctance to address the issue.

Pharmaceutical Care Network Europe definition of quality indicators for pharmaceutical care: a systematic literature review and international consensus development.

BACKGROUND: Over the past 40 years, the tasks of pharmacists have shifted from logistic services to pharmaceutical care (PhC). Despite the increasing importance of measuring quality of care, there is no general definition of Quality Indicators (QIs) to measure PhC. Recognising this, a working group in a European association of PhC researchers, the Pharmaceutical Care Network Europe (PCNE), was established in 2020. AIM: This research aimed to review existing definitions of QIs and develop a definition of QIs for PhC. METHOD: A two-step procedure was applied. Firstly, a systematic literature review was conducted to identify existing QI definitions that were summarised. Secondly, an expert panel, comprised of 17 international experts from 14 countries, participated in two surveys and a discussion using a modified Delphi technique to develop the definition of QIs for PhC. RESULTS: A total of 182 QI definitions were identified from 174 articles. Of these, 63 QI definitions (35%) cited one of five references as the source. Sixteen aspects that construct QI definitions were derived from the identified definitions. As a result of the Delphi study, the panel reached an agreement on a one-sentence definition of QIs for PhC: "quality indicators for pharmaceutical care are validated measurement tools to monitor structures, processes or outcomes in the context of care provided by pharmacists". CONCLUSION: Building upon existing definition of QIs, an international expert panel developed the PCNE definition of QIs for PhC. This definition is intended for universal use amongst researchers and healthcare providers in PhC.

A Trial-Based Cost-Utility Analysis of a Medication Optimization Intervention Versus Standard Care in Older Adults.

BACKGROUND: Older adults are at greater risk of medication-related harm than younger adults. The Integrated Medication Management model is an interdisciplinary method aiming to optimize medication therapy and improve patient outcomes. OBJECTIVE: We aimed to investigate the cost effectiveness of a medication optimization intervention compared to standard care in acutely hospitalized older adults. METHODS: A cost-utility analysis including 285 adults aged ≥ 70 years was carried out alongside the IMMENSE study. Quality-adjusted life years (QALYs) were derived using the EuroQol 5-Dimension 3-Level Health State Questionnaire (EQ-5D-3L). Patient-level data for healthcare use and costs were obtained from administrative registers, taking a healthcare perspective. The incremental cost-effectiveness ratio was estimated for a 12-month follow-up and compared to a societal willingness-to-pay range of €/QALY 27,067-81,200 (NOK 275,000-825,000). Because of a capacity issue in a primary care resulting in extended hospital stays, a subgroup analysis was carried out for non-long and long stayers with hospitalizations < 14 days or ≥ 14 days. RESULTS: Mean QALYs were 0.023 [95% confidence interval [CI] 0.022-0.025] higher and mean healthcare costs were €4429 [95% CI - 1101 to 11,926] higher for the intervention group in a full population analysis. This produced an incremental cost-effectiveness ratio of €192,565/QALY. For the subgroup analysis, mean QALYs were 0.067 [95% CI 0.066-0.070, n = 222] and - 0.101 [95% CI - 0.035 to 0.048, n = 63] for the intervention group in the non-long stayers and long stayers, respectively. Corresponding mean costs were €- 824 [95% CI - 3869 to 2066] and €1992 [95% CI - 17,964 to 18,811], respectively. The intervention dominated standard care for the non-long stayers with a probability of cost effectiveness of 93.1-99.2% for the whole willingness-to-pay range and 67.8% at a zero willingness to pay. Hospitalizations were the main cost driver, and readmissions contributed the most to the cost difference between the groups. CONCLUSIONS: According to societal willingness-to-pay thresholds, the medication optimization intervention was not cost effective compared to standard care for the full population. The intervention dominated standard care for the non-long stayers, with a high probability of cost effectiveness. CLINICAL TRIAL REGISTRATION: The IMMENSE trial was registered in ClinicalTrials.gov on 28 June, 2016 before enrolment started (NCT02816086).

Exploring stakeholders' perspectives on the quality of services provided through community pharmacies.

INTRODUCTION: It is important to understand the factors impacting the quality of services provided through community pharmacies. Exploring how key stakeholders perceive good quality in these services is a logical first step. This could also inform the development of quality measures, such as quality indicators (QIs). AIM: To identify key stakeholders' perspectives on the quality of services provided through community pharmacies in Norway, specifically by exploring their experiences and perceptions about what constitutes good service quality. METHODS: A convenient sampling approach was used to recruit participants for five semi-structured focus groups from Facebook, pharmacy chains, and patient organizations. The interviews with twenty-six participants were conducted via Microsoft Teams. Interviews were transcribed verbatim, and an inductive thematic analysis with a reflexive approach was used. RESULTS: Four main themes emerged from the analysis; 1) sufficient and substantively suitable information to cover individual needs, 2) communication skills and relationships with the pharmacy professionals, 3) customer satisfaction with knowledgeable employees and conveniently located pharmacies, and 4) factors that affect the pharmacy working environment. CONCLUSION: This study has identified areas that pharmacy professionals and customers regard as essential to define good quality of community pharmacy services. Effective communication skills, appropriate provision of information, customer satisfaction, and working environment are all essential factors when developing quality metrics for community pharmacies.

'Illuminating determinants of implementation of non-dispensing pharmacist services in home care: a qualitative interview study'.

OBJECTIVES: Medication errors are leading causes of hospitalization and death in western countries and WHO encourages health care providers to implement non-dispensing pharmacist services in primary care to improve medication work. However, these services struggle to provide any impact on clinical outcomes. We wanted to explore health care professionals' views on medication work to illuminate determinants of the implementation success. The research was designed to inform and adapt implementation strategies for non-dispensing pharmacist services. DESIGN: Semi-structured interview study with nine healthcare professionals. SETTING: Four Norwegian home care wards. SUBJECTS: Nine healthcare professionals working at different wards within one home care unit. MAIN OUTCOME MEASURES: Determinants of implementation outcomes. RESULTS: Contextual determinants of the implementation process were mainly related to characteristics of the setting such as poorly designed information systems, work overload, and chaotic work environments. The identified barriers question the innovation's appropriateness related to the setting's needs but also provide possibilities for tailoring pharmacist services to local medication work issues. The observable positive effects and the perceived advantage of the pharmacist services are likely to facilitate the implementation process. CONCLUSION: Our study provided information on contextual elements that influence the implementation process of non-dispensing pharmacist services. Awareness of these factors can help develop strategies to help the organization succeed in in achieving program outcomes.

The results in this study illuminate barriers and facilitators to the implementation of pharmacist services in a home care setting.Existing medication work methods and poor information handover systems are likely to counteract outcomes of the pharmacist services and inflict unfavorable conditions for implementation.Healthcare professionals' perception of increased medication work support and confidence in pharmacist skills suggest innovation acceptability and serve as indicators of implementation success. The identified barriers to improving medication work provide opportunities to develop tailored strategies to enhance the implementation of non-dispensing pharmacist services.

Is anticholinergic and sedative drug burden associated with postdischarge institutionalization in community-dwelling older patients acutely admitted to hospital? A Norwegian registry-based study.

PURPOSE: Investigate the association between anticholinergic (AC) and sedative (SED) drug burden before hospitalization and postdischarge institutionalization (PDI) in community-dwelling older patients acutely admitted to hospital. METHODS: A cross-sectional study using data from the Norwegian Patient Registry and the Norwegian Prescription Database. We studied acutely hospitalized community-dwelling patients ≥70 years during 2013 (N = 86 509). Patients acutely admitted to geriatric wards underwent subgroup analyses (n = 1715). We calculated drug burden by the Drug Burden Index (DBI), use of AC/SED drugs, and the number of AC/SED drugs. Piecewise linearity of DBI versus PDI and a knot point (DBI = 2.45) was identified. Statistical analyses included an adjusted multivariable logistic regression model. RESULTS: In the total population, 45.4% were exposed to at least one AC/SED drug, compared to 52.5% in the geriatric subgroup. AC/SED drugs were significantly associated with PDI. The DBI with odds ratios (ORs) of 1.11 (95% CI 1.07-1.15) for DBI < 2.45 and 1.08 (95% CI 1.04-1.13) for DBI ≥ 2.45. The number of AC/SED drugs with OR of 1.07 (95% CI 1.05-1.09). The AC component of DBI with OR 1.23 and the number of AC drugs with OR 1.13. In the subgroup, ORs were closer to 1 for AC drugs. CONCLUSIONS: The use of AC/SED drugs was highly prevalent in older patients before acute hospital admissions, and significantly associated with PDI. The number, or just using AC/SED drugs, gave similar associations with PDI compared to applying the DBI. Using AC drugs showed higher sensitivity, indicating that to reduce the risk of PDI, a clinical approach could be to reduce the number of AC drugs.

Self-reported medication information needs among medication users in a general population aged 40 years and above - the Tromsø study.

PURPOSE: To determine the prevalence and associated factors of self-reported medication information needs among medication users in a general population aged 40 years and above - The Tromsø Study. METHODS: Cross-sectional study of medication users (n = 10,231) among participants in the Tromsø Study, a descriptive analysis of questionnaire data and multivariable logistic regression (n = 9,194). RESULTS: Sixteen percent of medication users expressed a need for more information about own medications. Overall, medication users agreed to a higher degree to have received information from the GP compared to the pharmacy. Concerned medication users and those disagreeing to have received information about side effects had the highest odds for needing more information (OR 5.07, 95% CI 4.43-5.81) and (OR 2.21, 95% CI 1.83-2.68), respectively. Medication users who used heart medications (e.g., nitroglycerin, antiarrhythmics, anticoagulants) (OR 1.71, 95% CI 1.46-2.01), medication for hypothyroidism (OR 1.36, 95% CI 1.13-1.64) or had moderately health anxiety had expressed need for medication information. Whereas medication users with lower education, those that never used internet to search for health advice, and medication users who disagreed to have received information about reason-for-use were associated with lower odds (OR 0.75, 95% CI 0.62-0.91), (OR 0.85, 95% CI 0.74-0.98) and (OR 0.68, 95% CI 0.53-0.88), respectively. CONCLUSION: This study demonstrated that there is need for more information about own medications in a general population aged 40 years and above and shed light on several characteristics of medication users with expressed information need which is important when tailoring the right information to the right person.

Interdisciplinary collaboration across secondary and primary care to improve medication safety in the elderly (The IMMENSE study) - a randomized controlled trial.

BACKGROUND: Suboptimal medication use contributes to a substantial proportion of hospitalizations and emergency department visits in older adults. We designed a clinical pharmacist intervention to optimize medication therapy in older hospitalized patients. Based on the integrated medicine management (IMM) model, the 5-step IMMENSE intervention comprise medication reconciliation, medication review, reconciled medication list upon discharge, patient counselling, and post discharge communication with primary care. The objective of this study was to evaluate the effects of the intervention on healthcare use and mortality. METHODS: A non-blinded parallel group randomized controlled trial was conducted in two internal medicine wards at the University Hospital of North Norway. Acutely admitted patients ≥ 70 years were randomized 1:1 to intervention or standard care (control). The primary outcome was the rate of emergency medical visits (readmissions and emergency department visits) 12 months after discharge. RESULTS: Of the 1510 patients assessed for eligibility, 662 patients were asked to participate, and 516 were enrolled. After withdrawal of consent and deaths in hospital, the modified intention-to-treat population comprised 480 patients with a mean age of 83.1 years (SD: 6.3); 244 intervention patients and 236 control patients. The number of emergency medical visits in the intervention and control group was 497 and 499, respectively, and no statistically significant difference was observed in rate of the primary outcome between the groups [adjusted incidence rate ratio of 1.02 (95% CI: 0.82-1.27)]. No statistically significant differences between groups were observed for any of the secondary outcomes, neither in subgroups, nor for the per-protocol population. CONCLUSIONS: We did not observe any statistical significant effects of the IMMENSE intervention on the rate of emergency medical visits or any other secondary outcomes after 12 months in hospitalized older adults included in this study. TRIAL REGISTRATION: The trial was registered in clinicaltrials.gov on 28/06/2016, before enrolment started (NCT02816086).

Medication adherence among persons with coronary heart disease and associations with blood pressure and low-density-lipoprotein-cholesterol.

PURPOSE: To describe medication adherence to lipid-lowering drugs (LLDs), antihypertensive drugs, and acetylsalicylic acid (ASA) among persons with coronary heart disease (CHD) and explore its association with low-density-lipoprotein (LDL)-cholesterol, and systolic and diastolic blood pressure. METHODS: Based on record linkage between the seventh wave of the Tromsø Study and the Norwegian Prescription Database, medication adherence was calculated as the proportion of days covered (PDC) for persistent prevalent users in the period of 365 days before the attendance date. Multivariable linear regression models were used to assess the association between systolic and diastolic blood pressure and medication nonadherence to antihypertensive drugs, age, sex, lifestyle, body mass index (BMI), current and previous diabetes, and between LDL-cholesterol and medication nonadherence to LLDs, age, sex, lifestyle, BMI, and current and previous diabetes. RESULTS: Mean PDC was 0.94 for LLDs and antihypertensive drugs and 0.97 for ASA. Among persons with PDC ≥ 0.80 for LLDs, 12.0% had an LDL-cholesterol < 1.8 mmol/L. Blood pressure < 140/90 mmHg (< 140/80 mmHg if diabetes patient) was reached by 55.1% of those with a PDC ≥ 0.80 for antihypertensive drugs. Adherence to LLDs was associated with lower LDL-cholesterol, while neither systolic nor diastolic blood pressure was associated with adherence to antihypertensive drugs. CONCLUSION: Adherence to antihypertensive drugs, LLDs, and ASA among persons with CHD were high despite low achievement of treatment goals for blood pressure and LDL-cholesterol. There was a statistically significant association between adherence to LLDs and LDL-cholesterol, but not between adherence to antihypertensive drugs and blood pressure.

Intervention fidelity and process outcomes of the IMMENSE study, a pharmacist-led interdisciplinary intervention to improve medication safety in older hospitalized patients.

WHAT IS KNOWN AND OBJECTIVE: The majority of hospitalized older patients experience medication-related problems (MRPs), and there is a call for interventions to solve MRPs and improve clinical outcomes like medical visits. The IMMENSE study is a randomized controlled trial investigating the impact of a pharmacist-led interdisciplinary intervention on emergency medical visits. Its multistep intervention is based on the integrated medicines management methodology and includes a follow-up step with primary care. This study aims to describe how the intervention in the IMMENSE study was delivered and its process outcomes. METHODS: The study includes the 221 intervention patients in the per-protocol group of the IMMENSE study. Both intervention delivery, reasons for not performing interventions and process outcomes were registered daily by the study pharmacists in a Microsoft Access® database. Process outcomes were medication discrepancies, MRPs and how the team solved these. RESULTS AND DISCUSSION: A total of 121 (54.8%) patients received all intervention steps if appropriate. All patients received medication reconciliation (MedRec) and medication Review (MedRev) (step 1 and 2), while between 10% and 20% of patients were missed for medication list in discharge summary (step 3), patient counselling (step 4), or communication with general practitioner and nurse (step 5). A total of 437 discrepancies were identified in 159 (71.9%) patients during MedRec, and 1042 MRPs were identified in 209 (94.6%) patients during MedRev. Of these, 292 (66.8%) and 700 (67.2%), respectively, were communicated to and solved by the interdisciplinary team during the hospital stay. WHAT IS NEW AND CONCLUSION: The fidelity of the single steps of the intervention was high even though only about half of the patients received all intervention steps. The impact of the intervention may be influenced by not implementing all steps in all patients, but the many discrepancies and MRPs identified and solved for the patients could explain a potential effect of the IMMENSE study.

Home care service employees' contribution to patient safety in clients with dementia who use dietary supplements: a Norwegian survey.

OBJECTIVE: To explore home care services (HCS) employees' professional experiences with the use of dietary supplements (DSs) in their clients with dementia. We also investigated their attributed professional responsibility concerning this use and their attitudes toward DSs in general. Differences between nurses and nurse assistants were investigated. DESIGN: A cross-sectional survey with self-administered questionnaires. SETTING: Home care services in six Norwegian municipalities in the period August-December 2016. SUBJECTS: A total of 231 (64% response rate) HCS employees; 78 nurses and 153 nurse assistants (auxiliary nurses and employees without formal education).Main outcome measures: Health care employees' experiences with patient safety in clients with dementia who use DSs. RESULTS: Fifty per cent were concerned that clients with dementia might harm their health due to DS use. Thirty-one per cent reported having intervened in order to reduce the risk. Seventy-one per cent preferred to administer DSs to clients with dementia rather than leaving this responsibility to the clients. The respondents placed the responsibility for patient safety in clients with dementia using DSs mainly with the general practitioners, while they ascribed themselves and pharmacies a medium level of responsibility. There were only minor difference between nurses and nurse assistants, and no difference in attitudes towards DSs. CONCLUSION: Employees in HCS were concerned about the DS use in clients with dementia. Moreover, almost one-third had intervened to improve clients' patient safety. The majority indicated that HCS should administer DSs rather than the clients with dementia themselves.KEY POINTSTo our knowledge, this is the first study investigating the role of home care services with regard to patient safety in clients with dementia who use dietary supplements (DSs).•Home care service employees worried about patient safety related to DS use in clients with dementia.•Home care service employees attributed to themselves medium responsibility to ensure the safe use of DSs in these clients.•Lack of knowledge was the most important reason why home care service employees did not recommend DSs to clients.

Time distribution for pharmacists conducting a randomized controlled trial-An observational time and motion study.

INTRODUCTION: An expected future increase in older adults will demand changes in health care delivery, making development, implementation and evaluation of new health care models essential. The rationale for political decision-making concerning the implementation and application of interventions in health care should include cost estimations, specifically those involving clinical interventions. To provide such data knowledge of time spent on the intervention is imperative. Time and motion methodology is suitable to quantify health care personnel's time distribution. AIM: To investigate the time distribution for pharmacists conducting a randomized controlled trial (RCT) implementing a clinical intervention. MATERIALS AND METHODS: The setting was an RCT with a 5-step pharmacist-intervention in collaboration with the interdisciplinary team in a geriatric ward. Two pharmacists were involved in the trial during the observation period. Pharmacist activities, classified as RCT-tasks (intervention or administrative), non-RCT tasks and social/breaks, were recorded applying the Work Observation Method By Activity Timing methodology, enabling recording of predefined work tasks as well as interruptions and multitasking. One observer collected data over eight weeks. RESULTS: In total, 109.1 hours were observed resulting in 110.2 hours total task time, including multitasking. RCT tasks comprised 85.4% of the total observed time, and nearly 60% of the RCT time was spent on intervention tasks. Medication reviews was the most time consuming task, accounting for 32% of the observed time. The clinical pharmacists spent 14% of the intervention time communicating verbally, mainly with patients and healthcare professionals. CONCLUSION: During the RCT, the clinical pharmacists spent about half their time performing the actual intervention. Consequently, costs for providing such a clinical pharmacist service should reflect actual time spent; otherwise, we may risk overestimating theoretical costs.

Self-medication Behavior with antibiotics: a national cross-sectional survey in Sri Lanka.

BACKGROUND: Antibiotic self-medication is common in low- and middle-income countries. This study aimed to evaluate the Sri Lankan public's knowledge about and attitudes toward antibiotic use and self-medication, and factors associated with self-medication. METHODS: A national cross-sectional, interviewer-administered, survey of a random household sample (N = 1100) was conducted. Factor analysis of the attitudinal items was conducted to investigate the factors associated with antibiotic self-medication. RESULTS: A response rate of ninety-one percent (n = 998) responded. Knowledge about antibiotics was poor (mean = 12.5; SD = 3.5; (scale 0-27)). Half had previously used an antibiotic once in the past three months. About 11% (108/998) had self-medicated the last time they took antibiotics; mostly obtained from a pharmacy (82%; 89/108). Three attitudinal factors were obtained, explaining 56.1% of the variance. Respondents were less likely to self-medicate if they did not support ease of access to antibiotics from pharmacies (p< 0.001) and situational use of antibiotics (p= 0.001); supported appropriate use of antibiotics (p= 0.003); and had greater knowledge about prescription requirements for antibiotics (p= 0.004). CONCLUSION: There is limited knowledge about, and a high rate of self-medication with antibiotics.Factors contributing to self-medication could be addressed with appropriate public education campaigns, and policy changes.

Self-reported medication use among coronary heart disease patients showed high validity compared with dispensing data.

OBJECTIVE: To validate self-reported use of medications for secondary prevention of coronary heart disease (CHD) in a population-based health study by comparing self-report with pharmacy dispensing data, and explore different methods for defining medication use in prescription databases. STUDY DESIGN AND SETTING: Self-reported medication use among participants with CHD (n = 1483) from the seventh wave of the Tromsø Study was linked with the Norwegian Prescription Database (NorPD). Cohen's kappa, sensitivity, specificity, and positive and negative predictive values were calculated, using NorPD as the reference standard. Medication use in NorPD was defined in three ways; fixed-time window of 180 days, and legend-time method assuming a daily dose of one dosage unit or one defined daily dose (DDD). RESULTS: Kappa-values for antihypertensive drugs, lipid-lowering drugs and acetylsalicylic acid all showed substantial agreement (kappa ≥0.61). Validity varied depending on the method used for defining medication use in NorPD. Applying a fixed-time window gave higher agreement, positive predictive values and specificity compared with the legend-time methods. CONCLUSION: Self-reported use of medication for secondary prevention of CHD shows high validity when compared with pharmacy dispensing data. For CHD medications, fixed-time window appears to be the most appropriate method for defining medication use in prescription databases.

Adherence to prescription guidelines and achievement of treatment goals among persons with coronary heart disease in Tromsø 7.

BACKGROUND: Adherence to clinical practice guidelines for coronary heart disease (CHD) reduces morbidity, mortality and treatment costs. We aimed to describe and compare adherence to prescription guidelines for persons with CHD, and explore its association with treatment goal achievement. METHOD: We included all participants reporting myocardial infarction, angina, percutaneous coronary intervention and/or coronary artery bypass surgery in the seventh wave of the Tromsø Study (2015-2016, n = 1483). Medication use and treatment goal measures (blood pressure, low-density lipoprotein (LDL)-cholesterol and HbA1c) were compared to clinical practice guidelines on secondary CHD prevention. Propensity score matched logistic regression was used to assess the association between the use of antihypertensive drugs and achievement of treatment goal for blood pressure, and the use of lipid-lowering drugs (LLDs) and achievement of treatment goal for LDL-cholesterol. RESULTS: The prevalence of pharmacological CHD treatment was 76% for LLDs, 72% for antihypertensive drugs and 66% for acetylsalicylic acid. The blood pressure goal (< 140/90 mmHg, < 140/80 mmHg if diabetic) was achieved by 58% and the LDL-cholesterol goal (< 1.8 mmol/l or < 70 mg/dL) by 9%. There was a strong association between using LLDs and achieving the treatment goal for LDL-cholesterol (OR 14.0, 95% CI 3.6-54.7), but not between using antihypertensive drugs and blood pressure goal achievement (OR 1.4, 95% CI 0.7-2.7). CONCLUSION: Treatment goal achievement of LDL-cholesterol and blood pressure was low, despite the relatively high use of LLDs and antihypertensive drugs. Further research is needed to find the proper actions to increase achievement of the treatment goals.

The impact of hospitalisation to geriatric wards on the use of medications and potentially inappropriate medications - a health register study.

BACKGROUND: The use of potentially inappropriate medications (PIMs) are associated with negative health effects for older adults. The purpose of this study was to apply national register data to investigate the impact of hospitalisation to geriatric wards in Norway on the use of medications and PIMs, and to compare two explicit PIM identification tools. METHODS: We included 715 patients ≥65 years (mean 82.5, SD = 7.8) admitted to Norwegian geriatric wards in 2013 identified from The Norwegian Patient Registry, and collected their medication use from the Norwegian Prescription Database. Medication use before and after hospitalisation was compared and screened for PIMs applying a subset of the European Union (EU)(7)-PIM list and the Norwegian General Practice - Nursing Home (NORGEP-NH) list part A and B. RESULTS: The mean number of medications increased from 6.5 (SD = 3.5) before to 7.5 (SD = 3.5) (CI:1.2-0.8, p < 0.001) after hospitalisation. The proportion of patients with PIMs increased from before to after hospitalisation according to the EU(7)-PIM list (from 62.4 to 69.2%, p < 0.001), but not according to The NORGEP-NH list (from 49.9 to 50.6%, p = 0.73). The EU(7)-PIM list and the NORGEP-NH list had more than 70% agreement on the classification of patients as PIM users. CONCLUSIONS: Medication use increased after hospitalisation to geriatric wards. We did not find that geriatric hospital care leads to a general improvement in PIM use after hospitalisation. According to a subset of the EU(7)-PIM list, PIM use increased after hospitalisation. This increase was not identified by the NORGEP-NH list part A and B. It is feasible to use health register data to investigate the impact of hospitalisation to geriatric wards on medication use and PIMs.
