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).

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.

Medication dose calculation errors and other numeracy mishaps in hospitals: Analysis of the nature and enablers of incident reports.

AIMS: To investigate medication dose calculation errors and other numeracy mishaps in hospitals and examine mechanisms and enablers which lead to such errors. DESIGN: A retrospective study using descriptive statistics and thematic analysis of the nature and enablers of reported incidents. METHODS: Medication dose calculation errors and other numeracy mishaps were identified from medication-related incidents reported to the Norwegian Incident Reporting System in 2016 and 2017. The main outcome measures were medications and medication classes involved, severity of harm, outcome, and error enablers. RESULTS: In total, we identified 100 numeracy errors, of which most involved intravenous administration route (n = 70). Analgesics were the most commonly reported drug class and morphine was the most common individual medication. Overall, 78 incidents described patient harm. Frequent mechanisms were 10- or 100-fold errors, mixing up units, and incorrect strength/rate entered into infusion pumps. The most frequent error enablers were: double check omitted or deviated (n = 40), lack of safety barriers to intercept prescribing errors (n = 25), and emergency/stress (n = 21). CONCLUSION: Numeracy errors due to lack of or improper safeguards occurred during all medication management stages. Dose miscalculation after dilution of intravenous solutions, infusion pump programming, and double-checking were identified as unsafe practices. We discuss measures to prevent future calculation and numeracy errors. IMPACT: Our analysis of medication dose calculation errors and other numeracy mishaps demonstrates the need for improving safety steps and increase standardization for medication management procedures. We discuss organizational, technological, and educational measures to prevent harm from numeracy errors.

Implementation of a shared medication list in primary care - a controlled pre-post study of medication discrepancies.

BACKGROUND: Access to medicines information is important when treating patients, yet discrepancies in medication records are common. Many countries are developing shared medication lists across health care providers. These systems can improve information sharing, but little is known about how they affect the need for medication reconciliation. The aim of this study was to investigate whether an electronically Shared Medication List (eSML) reduced discrepancies between medication lists in primary care. METHODS: In 2018, eSML was tested for patients in home care who received multidose drug dispensing (MDD) in Oslo, Norway. We followed this transition from the current paper-based medication list to an eSML. Medication lists from the GP, home care service and community pharmacy were compared 3 months before the implementation and 18 months after. MDD patients in a neighbouring district in Oslo served as a control group. RESULTS: One hundred eighty-nine patients were included (100 intervention; 89 control). Discrepancies were reduced from 389 to 122 (p <  0.001) in the intervention group, and from 521 to 503 in the control group (p = 0.734). After the implementation, the share of mutual prescription items increased from 77 to 94%. Missing prescriptions for psycholeptics, analgesics and dietary supplements was reduced the most. CONCLUSIONS: The eSML greatly decreases discrepancies between the GP, home care and pharmacy medication lists, but does not eliminate the need for medication reconciliation.

Potentially inappropriate prescribing to older patients receiving multidose drug dispensing.

BACKGROUND: Multidose drug dispensing (MDD) is an adherence aid that provides patients with machine-dispensed medicines in disposable unit bags, usually for a 14 day period. Previous studies have suggested that the quality of prescribing, with time, is lower for MDD users, compared to patients receiving prescriptions dispensed as usual. This study aimed to examine the quality of prescribing to Norwegian elderly home care service patients receiving MDD. METHODS: A cross-sectional study comprising 45,593 MDD patients aged ≥70 years was performed. The proportion of potentially inappropriate medications (PIMs) was assessed using the Norwegian General Practice Criteria, and drug-drug interactions (DDI) were investigated using the Norwegian Medicines Agency database. RESULTS: On average, patients were prescribed 10.6 drugs (SD = 5.0), of which 6.1 were dispensed via MDD. Men used on average fewer drugs than women (10.7 vs 11.1), Twenty-seven percent of patients used at least one PIM. Concomitant use of three or more psychotropic drugs (10.8%), and prescribing of diazepam (6.4%) was the most commonly identified inappropriate prescribing. DDIs affected 59% of the patients, however, only 2.7% had serious interactions. Women were more frequently exposed to both PIMs and DDIs than men, with an odds ratio of 1.50 (95% CI: 1.43-1.58) and 1.43 (95% CI: 1.37-1.50), respectively. CONCLUSIONS: Polypharmacy is common in elderly Norwegian patients using MDD. About one-fourth of the patients were exposed to PIMs, and over half were exposed to DDI.

Prescribing of NOACs has outnumbered warfarin: exploring how physicians choose anticoagulant treatments.

PURPOSE: The development of non-vitamin K-dependent oral anticoagulants (NOACs) is a new alternative to treatment with warfarin. The purpose of this study was to explore drug prescription decisions of NOACs or warfarin from hospital physicians in cardiovascular departments. METHODS: A qualitative study with focus group interviews was conducted in three different hospitals. The interview guide explored the background of prescribing anticoagulants (warfarin, dabigatran, rivaroxaban, and apixaban) and experiences with effect and side-effects they had observed in patients. RESULTS: The systematic text condensation eluded four main themes: when to prescribe NOACs, concern about side-effects, pharmaceutical properties and patient adherence, and prescribing policy and intra-professional communication. All available anticoagulants were prescribed. However, no specific NOAC was preferred. Factors perceived as contraindications for NOACs varied among the doctors. Most had observed side-effects of NOACs; however, these rarely influenced prescribing decisions due to small differences in safety profiles. Few drug-drug interactions and fixed daily doses made NOACs easy to prescribe; but some doctors had experienced lack of drug effect for some patients. Non-adherence with NOACs was harder to spot. Some different prescribing cultures had evolved between the different hospitals and between general practitioners. CONCLUSION: The hospital physicians chose anticoagulants based on patient conditions as renal function, bleeding risks, and drug interactions being the most common taken into account. They could not say which NOAC was best, and wish that future studies could compare the different NOACs, and not just compare with warfarin.

Elderly users of fall-risk-increasing drug perceptions of fall risk and the relation to their drug use - a qualitative study.

OBJECTIVE: The aim of the study was to explore how home-dwelling elderly who use fall-risk-increasing drugs (FRIDs) perceive their fall risk and how they relate this to their drug use. DESIGN, SETTING AND SUBJECTS: A qualitative study with 14 home-dwelling elderly FRID users between 65 and 97 years in Central Norway participating in semi-structured individual interviews. The data were analyzed thematically by using systematic text condensation. RESULTS: The main finding was that the informants did not necessarily perceive the use of FRIDs to be a prominent risk factor for falls. Some informants said they did not reflect upon drug use whatsoever and said they fully trusted their physician's choices. When either experiencing dizziness, fall episodes or by reading the patient information leaflet the informants said to either adjust their drug use or to contact their physician. Some felt rejected due to not getting their point across or their wish to alter the drug was not granted by the physician. CONCLUSIONS: Elderly FRID users did not necessarily relate their drug use to fall risk or struggled to present their perceived drug-related problems. Physicians need to regularly inform, monitor and assess the drug treatment when treating elderly with FRIDs.

'I try not to bother the residents too much' - the use of capillary blood glucose measurements in nursing homes.

BACKGROUND: Capillary blood glucose measurements are regularly used for nursing home residents with diabetes. The usefulness of these measurements relies on clear indications for use, correct measurement techniques, proper documentation and clinical use of the resulting blood glucose values. The use of a regular, invasive procedure may also entail additional challenges in a population of older, multimorbid patients who often suffer from cognitive impairment or dementia. The aim of this study was to explore the perspectives of physicians, registered nurses and auxiliary nurses on the use, usefulness and potential challenges of using capillary blood glucose measurements in nursing homes, and the procedures for doing so. METHODS: This was a qualitative study that used three profession-specific focus group interviews. Interviews were transcribed in modified verbatim form and analysed in accordance with Malterud's principles of systematic text condensation. Five physicians, four registered nurses and three auxiliary nurses participated in the focus groups. RESULTS: All professional groups regarded capillary blood glucose measurements as a necessity in the management of diabetes, the physicians to ensure that the treatment is appropriate, and the nurses to be certain and assured about their caring decisions. Strict glycaemic control and excessive measurements were avoided in order to promote the well-being and safety of the residents. Sufficient knowledge of diabetes symptoms, equivalent practices for glucose measurement, and unambiguous documentation and communication of results were determined to be most helpful. However, all professional groups seldom involved the residents in managing their own measurements and stated that guidelines and training had been inconsistent or lacking. CONCLUSION: Inadequate procedures and training in diabetes care may compromise the rationale for capillary blood glucose measurements in nursing homes, and hence the residents' safety. These concerns should be addressed together with the possibility of involving and empowering residents by exploring their ability and wish to manage their own disease.

Factors influencing prescribing of fall-risk-increasing drugs to the elderly: A qualitative study.

OBJECTIVE: Explore the situations in which GPs associate drug use with falls among their elderly patients, and the factors influencing the prescribing and cessation of fall-risk-increasing drugs (FRIDs). DESIGN: A qualitative study with 13 GPs who participated in two semi-structured focus groups in Central Norway. Participants were encouraged to share overall thoughts on the use of FRIDs among elderly patients and stories related to prescribing and cessation of FRIDs in their own practice. RESULTS: The main finding was that GPs did not immediately perceive the use of FRIDs to be a prominent factor regarding falls in elderly patients, exceptions being when the patient presented with dizziness, reported a fall, or when prescribing FRIDs for the first time. It was reported as common to renew prescriptions without performing a drug review. Factors influencing the prescribing and cessation of FRIDs were categorized into GPs' clinical work conditions, uncertainty about outcome of changing prescriptions, patients' prescribing demands, and lack of patient information. CONCLUSIONS: The results from this study indicate that GPs need to be reminded that there is a connection between FRID use and falls among elderly patients of enough clinical relevance to remember to assess the patient's drug list and perform regular drug reviews.

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).

Prescribing quality for older people in Norwegian nursing homes and home nursing services using multidose dispensed drugs.

PURPOSE: To examine and compare the quality of drug prescribing for older patients in nursing homes and home nursing services. METHODS: Cross-sectional study comprising 11,254 patients aged ≥ 65 years in nursing homes (n = 2986) and home nursing services (n = 8268). Potentially inappropriate medications were identified by using the Norwegian General Practice criteria and drug-drug interactions through a Norwegian Web-based tool. The impact of care setting on exposure to selected drug groups, potentially inappropriate medications, and drug interactions was calculated, adjusting for patients' age, gender, and number of drugs used. RESULTS: Patients in nursing homes and home nursing services used on average 5.7 (SD = 2.6) multidose dispensed regular drugs. Twenty-six percent used at least one potentially inappropriate medication, 31% in nursing homes and 25% in home nursing services, p < .001. Concomitant use of three or more psychotropic and/or opioid drugs was the criterion most commonly identified in nursing homes (18%) and home nursing services (9%), p < .001. Compared with nursing homes, more patients in home nursing services used cardiovascular drugs and fewer patients used psychotropic drugs. Altogether, 8615 drug-drug interactions were identified in 55% of patients, 48% in nursing homes and 57% in home nursing services, p < .001. CONCLUSIONS: There are significant differences in the quality of drug prescribing in nursing homes compared with home nursing services. Explanations as to why these differences exist need to be further explored.

Regional differences in sales of glucometer strips and antidiabetics.

BACKGROUND: Studies have shown that the prevalence of diabetes in Norway is 3-5 %, and that approximately 97,000 Norwegian patients perform self-monitoring of blood glucose. There is a need for studies of geographical differences in diabetes prevalence and treatment. This study investigates differences between counties in the prevalence of patients treated with antidiabetics in Norway, and in the use of glucometer strips. MATERIAL AND METHOD: Data on the sale of antidiabetes medication to non-institutionalized patients were acquired from the Norwegian Register of Prescriptions, while corresponding data on glucometer strips were received from the Norwegian Health Economics Administration (HELFO). RESULTS: We found a nationwide prevalence of medicinally treated diabetes of 2.9 %. The corresponding prevalence of use of glucometer strips was 2.1 %. There was a 27.5 % difference between the counties with the highest and lowest prevalence of medicinally treated diabetes, while the difference in use of glucometer strips was 31.5 %. The average cost of antidiabetes drugs was 23.7 % higher in the county with the highest average expenditure compared with the county with the lowest expenditure. There was a difference of up to 44 % between counties in the average purchase of glucometer strips per person. INTERPRETATION: The geographical differences may be due to different availability of health services or different therapy traditions. A shortage of guidelines on the frequency of self-monitoring of blood glucose may also have a bearing on the differences.

Reimbursed Medication Adherence Enhancing Interventions in European Countries: Results of the EUREcA Study.

Introduction: Current literature lacks detailed understanding of the reimbursement framework of medication adherence enhancing interventions (MAEIs). As part of the ENABLE COST Action, the EUREcA ("EUropen REimbursement strategies for interventions targeting medication Adherence") study aimed to provide an in-depth overview of reimbursed MAEIs currently available in European countries at national and regional levels and to pave the way for further MAEIs to be implemented in the future. Methods: A web-based, cross-sectional survey was performed across 38 European countries and Israel. The survey questionnaire was developed as a result of an iterative process of discussion informed by a desk review. The survey was performed among invited ENABLE collaborators from June to July 2021. Besides descriptive analysis, association between country income and health care expenditure, and the availability of reimbursed MAEIs were also assessed. Results: The survey identified 13 reimbursed MAEIs in nine countries: multi-dose drug dispensing (n = 5), medication review (n = 4), smart device (n = 2), mobile application (n = 1), and patient education (n = 1). The median GDP per capita of countries having ≥1 reimbursed MAEI was significantly higher compared to countries having no reimbursed adherence intervention (33,888 EUR vs 16,620 EUR, respectively; p = 0.05). Conclusions: Our findings highlight that to date only a small number of MAEIs have been reimbursed in European countries. Comprehensive health technology assessment recommendations and multi-stakeholder collaboration could help removing barriers related to the implementation and reimbursement of MAEIs.

Online and Blended Learning Courses for Healthcare Professionals and Policymakers on Patients' Perspectives on Medicine: A Project Report.

In order for healthcare professionals to better engage with patients, they need to understand and integrate the perspectives of patients into their daily work. In this project, we developed two courses for healthcare professionals on patients' perspectives on medicine. One course was an online course that introduced the patients' perspectives on medicine and explained its importance for healthcare and health policy. The second course was a blended learning course, consisting of online modules and face-to-face webinars, which specified how to explore patients' perspectives in qualitative interviews, and how to develop implementation plans. Patients participated in the development, execution, and evaluation of both courses. Overall, more than 2000 healthcare professionals enrolled in the first course and, in just over a year, 191 participants completed the online course; 57 healthcare professionals registered in the second blended learning course and six participants completed both components of the course. The relevance of knowledge gained was positively evaluated. Participants especially appreciated the participation of patients. Based on the feedback, the second blended learning course was adapted to run online and both courses continue to be freely available to all interested healthcare professionals on the Coursera platform.

Reimbursed medication adherence enhancing interventions in 12 european countries: Current state of the art and future challenges.

Background: Medication non-adherence jeopardises the effectiveness of chronic therapies and negatively affects financial sustainability of healthcare systems. Available medication adherence-enhancing interventions (MAEIs) are utilised infrequently, and even more rarely reimbursed. The aim of this paper was to review reimbursed MAEIs across selected European countries. Methods: Data on reimbursed MAEIs were collected from European countries at the ENABLE Cost Action expert meeting in September 2021. The identified MAEIs were analysed and clustered according to their characteristics, direct vs. indirect relation to adherence, and the targeted adherence phase. Results: Out of 12 contributing countries, 10 reported reimbursed MAEIs, 28 in total, of which 20 were identified as MAEIs targeting adherence directly. Reimbursed MAEIs were most often performed by either doctors (n = 6), nurses (n = 6), or pharmacists (n = 3). The most common types of MAEIs were education (n = 6), medication regimen management (n = 5), and adherence monitoring feedback (n = 4). Only seven reimbursed MAEIs were technology-mediated, whereas 11 addressed two interlinked phases of medication adherence, i.e., implementation and persistence. Conclusion: Our review highlights the scarcity of reimbursed MAEIs across the selected European countries, and calls for their more frequent use and reimbursement.

Prescriptions from general practitioners and in hospital physicians requiring pharmacists' interventions.

PURPOSE: To study prescribing errors requiring pharmacists' interventions and to evaluate the potential clinical significance of the errors and omissions detected. METHODS: The pharmacists at ten community pharmacies and two out-patient hospital pharmacies recorded prescribing errors and corresponding interventions using a modified version of a previously developed registration scheme. Prescription errors with potential clinical significance were scored according to a modified version of Safety Assessment Code (SAC)-score RESULTS: During the study period 85,475 prescriptions were dispensed. A total of 2385 prescribing errors were detected on 2226 (2.6%) prescriptions. The proportion of prescriptions with errors and omissions was more than four times higher on prescriptions from hospital physicians (7.1%) than on prescriptions from general practitioners (1.5%). The information on the majority (62.2%) of the prescriptions with inaccuracies had to be clarified before the drug could be dispensed. About 1/4 of the errors and omissions were of potential importance for the drug therapy. An expert panel of physicians and pharmacists judged 85% of these errors and omissions to be clinically significant. Individual physicians and pharmacists judged the clinical importance of the detected prescribing errors somewhat differently. CONCLUSIONS: Pharmacists intervened on 2.6% of prescriptions, and the majority of the potentially clinically significant prescribing errors were judged as significant to the patient's drug therapy and safety.

Minor ailments in out-of-hours primary care: an observational study.

BACKGROUND: Many consultations are partly or totally spent on minor ailments. A minor ailment is defined as a health complaint which, by simple actions, patients could handle themselves. OBJECTIVE: To investigate the prevalence, type of conditions, and time spent on minor ailments in consultations in out-of-hours care in Norway. DESIGN AND SETTING: An observational study of consultations at six out-of-hours primary care centres was carried out during evenings and weekends in November and December 2008. Main outcome measures were number and type of minor ailments, as well as consultation time. The minor ailments were predefined by a list of conditions. Conditions which, by certain pre-set criteria, still needed a doctor's professional advice were reclassified as "no minor ailment". RESULTS: A total of 210 consultations were observed. The patients' mean age was 28 years (range 0-94). Cough, fever, sore throat, upper respiratory tract infection, and earache contributed 76% of the 211 minor ailments registered. After reclassification, 58 (28%) of the 210 consultations registered were classified as partly or totally a minor ailment. These minor ailments represented 18% of the doctors' total consultation time in the 210 observed consultations. CONCLUSION: More than a quarter of the observed consultations were partly or totally spent on addressing minor ailments. This shows a potential for empowering patients to rely on self-care also for minor ailments in out-of-hours primary care.
