Knowledge about oral preventive treatments in patients with migraine: A nationwide study

BACKGROUND

Patients' knowledge about their medications is key to guarantee therapeutic compliance in chronic diseases.

AIMS OF THE STUDY

To determine patients' knowledge of oral preventive treatment (OPT) in migraine.

METHODS

This is a cross-sectional study evaluating knowledge of medication with a validated questionnaire that assessed: therapeutic objective, process of use, safety and conservation.

RESULTS

198 patients were included. Mean age was 45.4 ± 11.5 years-old and 92.4% were women. A 61.1% of migraine patients did not know the medication they used, 55.1% showed insufficient knowledge and 6.1% had no knowledge. The most known dimension was conservation (80.3%) and the most unknown dimension of was safety (33.7%). In this regard, 82.3% considered that they should not take precautions when taking the treatment, 80.3% stated that it had no contraindications and 82.8% were unaware of possible interactions with other medications. Worse knowledge about OPT was associated with longer time since migraine onset (p = .049), higher scores on the Hospital Anxiety and Depression Scale (p = .021), less qualified jobs (p = .045), use of monotherapy (p = .001) and longer periods since OPT initiation (p = .013).

CONCLUSIONS

The majority of migraine patients did not adequately know their preventive treatment, despite identifying some of the items related to their medication. The present study shows that knowledge of patients about their preventive treatment should be evaluated in clinical practice and could help migraine patients in the correct use of OPT.

Health professionals perception and beliefs about drug- related problems on polymedicated older adults- a focus group study

BACKGROUND

Polymedicated older patients are at greater risk of suffering from adverse events. For this reason, the detection of both inappropriate polypharmacy and polypharmacy-associated Drug-Related Problems (DRPs) are essential to improve the health and wellbeing of older adults and to reduce healthcare costs. This work aims to explore health professionals' perceptions and opinions about polypharmacy and the handling of medicines by polymedicated older adults.

METHODS

Thirteen focus groups with 94 health professionals (20 community pharmacists, 40 general practitioners and, 34 nurses) were conducted in primary healthcare centers of the center region of Portugal. Participants were asked to discuss their perceptions and beliefs concerning DRPs in polymedicated older adults. The sessions were audiotaped. After the transcription and coding of focus group sessions, a thematic analysis was done.

RESULTS

The following four main themes emerged from the 13 focus group sessions: poor compliance and polypharmacy- A perpetuated vicious cycle, organization of the healthcare system, interaction and communication between the health professionals, and strategies to prevent inappropriate polypharmacy.

CONCLUSIONS

The lack of both an efficient network of information and Interaction and communication between Health professionals makes the detection and/ or prevention of polypharmacy in older adults difficult. The implementation of new models to manage and/or prevent polypharmacy based on health professional perception and beliefs is essential to prevent DRPs and improve compliance among older adults.

Voices of Polymedicated Older Patients: A Focus Group Approach

Polypharmacy in older adults is frequently associated with incorrect management of medicines, which causes drug-related problems and, subsequently, poor health outcomes. Understanding why older adults incorrectly manage their medicines is fundamental to health outcomes, however, it is an issue that remains poorly explored. The aim of this study is to examine older people’s perceptions, attitudes, beliefs, and concerns in the central region of Portugal. Thirteen focus groups with sixty-one older adults taking five or more prescription medicines were conducted to explore older patients’ perceptions and beliefs about and management of their medication. Sampling was conducted until theme saturation had been achieved. Transcripts were coded and data were obtained using the NVivo qualitative data-analysis software programme. Older adults recognise the importance of medicines for ensuring healthy ageing. Owing to a lack of literacy, however, they frequently commit medication mistakes and compromise their health outcomes. Promoting the literacy and empowerment of older patients, as well as strengthening the relationship between health professionals and patients, is crucial when it comes to addressing drug-related problems and improving health outcomes.

Enhanced learning and retention of medical information in Alzheimer's disease after differential outcomes training

BACKGROUND

Adherence to treatment is a crucial factor for patients who have chronic illnesses or multiple morbidities and polypharmacy, which is frequently found in older adults. The non-adherence to medications has important economic and social consequences as well as impacts on the health of the patients. One of the reasons that can explain the low adherence to treatment, is the memory deficits that are characteristics of this population and that are even more evident in cases that involve neurodegenerative diseases.

METHODS AND FINDINGS

In this study, we explore whether the differential outcomes procedure (DOP), which has been shown to be useful in improving discriminative learning and memory in different populations, may facilitate learning and retention of medical recommendations in older adults who have been diagnosed with Alzheimer's disease. The results demonstrate that when this procedure was applied, the patients showed improvements in learning and long-term retention of two pill/time of day associations in a situation that simulates adherence to medical prescriptions.

CONCLUSIONS

These findings contribute new data about the potential benefits of the DOP in patients with neurodegenerative disorders, highlighting the important role that this procedure could play in addressing important issues related to the health and quality of life of older adults, with or without neurodegenerative diseases, such as low adherence to medical treatments.

Inappropriate Use of Medication by Elderly, Polymedicated, or Multipathological Patients with Chronic Diseases

The growth of the aging population leads to the increase of chronic diseases, of the burden of multimorbility, and of the complexity polypharmacy. The prevalence of medication errors rises in patients with polypharmacy in primary care, and this is a major concern to healthcare systems. This study reviews the published literature on the inappropriate use of medicines in order to articulate recommendations on how to reduce it in chronic patients, particularly in those who are elderly, polymedicated, or multipathological. A systematic review of articles published from January 2000 to October 2015 was performed using MEDLINE, EMBASE, PsychInfo, Scopus, The Cochrane Library, and Index Medicus databases. We selected 80 studies in order to analyse the content that addressed the question under consideration. Our literature review found that half of patients know what their prescribed treatment is; that most of elderly people take five or more medications a day; that in elderly, polymedicated people, the probability of a medication error occurring is higher; that new tools have been recently developed to reduce errors; that elderly patients can understand written information but the presentation and format is an important factor; and that a high percentage of patients have remaining doubts after their visit. Thus, strategies based on the evidence should be applied in order to reduce medication errors.

[Interventions to optimize pharmacologic treatment in hospitalized older adults: a systematic review]

OBJECTIVE

To summarise the evidence on interventions aimed at optimising the drug treatment of hospitalised elderly patients.

MATERIAL AND METHODS

We conducted a search in the main medical literature databases, selecting prospective studies of hospitalised patients older than 65 years who underwent interventions aimed at optimising drug treatment, decreasing polypharmacy and improving the medication appropriateness, health outcomes and exploitation of the healthcare system.

RESULTS

We selected 18 studies whose interventions consisted of medication reviews, detection of predefined drugs as potentially inappropriate for the elderly, counselling from a specialised geriatric team, the use of a computer support system for prescriptions and specific training for the nursing team. Up to 14 studies assessed the medication appropriateness, 13 of which showed an improvement in one or more of the parameters. Seven studies measured the impact of the intervention on polypharmacy, but only one improved the outcomes compared with the control. Seven other studies analysed mortality, but none of them showed a reduction in that rate. Only 1 of 6 studies showed a reduction in the number of hospital readmissions, and 1 of 4 studies showed a reduction in the number of emergency department visits.

CONCLUSIONS

Despite the heterogeneity of the analysed interventions and variables, we obtained better results in the process variables (especially in medication appropriateness) than in those that measured health outcomes, which had greater variability.

[Level of knowledge of antibiotics prescribed in outpatients]

INTRODUCTION

The lack of patient knowledge about their medication is considered to be one of the main reasons for an inappropriate use.

OBJECTIVE

This study the level of knowledge in patients about their prescribed antibiotic, and describes some of the factors related to this.

DESIGN

A cross-sectional, descriptive and observational study with an analytical component. SITE: A community pharmacy in Murcia.

METHODS

The study form was offered to all customers who arrived to obtain antibiotics while the study was taking place. A validated form was used to determined the level of knowledge was a validated form.

RESULTS

A total of 126 patients, most of them women, with an average age of 44.6 years were included. Half of the study population had no knowledge which could ensure the correct use of the antibiotic they were taking. The «process of use» of the medication was the best known dimension by the study population, followed by the «therapeutic aim». The dimension related to the «safety» of the medication was the one with the lowest values. After a logistic regression, a link between the knowledge of the antibiotic and the «know the name of the antibiotic» (p=.05; r=2.15) and the «number of antibiotic the patient takes» (p=.02; r=0.30) variables.

CONCLUSIONS

The results show that there is a certain lack of information on the use of antibiotics by the study sample. Thes results could help to show the way to follow in future studies, targeted to meet the need of information.

A systematic review of patient medication error on self-administering medication at home

INTRODUCTION

Medication errors have been analyzed as a health professionals' responsibility (due to mistakes in prescription, preparation or dispensing). However, sometimes, patients themselves (or their caregivers) make mistakes in the administration of the medication. The epidemiology of patient medication errors (PEs) has been scarcely reviewed in spite of its impact on people, on therapeutic effectiveness and on incremental cost for the health systems.

AREAS COVERED

This study reviews and describes the methodological approaches and results of published studies on the frequency, causes and consequences of medication errors committed by patients at home. A review of research articles published between 1990 and 2014 was carried out using MEDLINE, Web-of-Knowledge, Scopus, Tripdatabase and Index Medicus.

EXPERT OPINION

The frequency of PE was situated between 19 and 59%. The elderly and the preschooler population constituted a higher number of mistakes than others. The most common were: incorrect dosage, forgetting, mixing up medications, failing to recall indications and taking out-of-date or inappropriately stored drugs. The majority of these mistakes have no negative consequences. Health literacy, information and communication and complexity of use of dispensing devices were identified as causes of PEs. Apps and other new technologies offer several opportunities for improving drug safety.

What older complex chronic patients need to know about their everyday medication for safe drug use

OBJECTIVE

To determine whether elderly patients with complex drug regimens have enough information to ensure safe drug use.

METHODS

A cross-sectional study was conducted in Spain based on interviews of a random sample of 265 patients aged over 65 and taking at least five drugs for multiple comorbidities. General practitioners reported on diagnoses, drugs, dosage and biochemical laboratory results. Patients were asked about the medications they were taking (with higher scores indicating greater knowledge).

RESULTS

The patients took an average of 7.9 medications (SD 3.0). The mean scores were low for precautions (mean 0.3, SD 0.7) and how to properly store medications (mean 2.0, SD 3.0). Scores were significantly higher when physicians regularly provided patients with information (F-test 3.3, p = 0.039) and were not related to gender, years of treatment or health status. Frequent changes in medication adversely affected the scores (p = 0.03). Higher scores were related to a smaller number of medication errors (t-test 2.2, p = 0.032, CI 95% of the difference 0.6 - 1.2).

CONCLUSIONS

Older complex chronic patients are unaware of the precautions they must adopt to use their medications safely. Patient knowledge does contribute to reducing medication errors. When physicians change prescriptions, modify doses or introduce new medications, more information needs to be provided for safe use of the drugs.

A Spanish pillbox app for elderly patients taking multiple medications: randomized controlled trial

Background

Nonadherence and medication errors are common among patients with complex drug regimens. Apps for smartphones and tablets are effective for improving adherence, but they have not been tested in elderly patients with complex chronic conditions and who typically have less experience with this type of technology.

Objective

The objective of this study was to design, implement, and evaluate a medication self-management app (called ALICE) for elderly patients taking multiple medications with the intention of improving adherence and safe medication use.

Methods

A single-blind randomized controlled trial was conducted with a control and an experimental group (N=99) in Spain in 2013. The characteristics of ALICE were specified based on the suggestions of 3 nominal groups with a total of 23 patients and a focus group with 7 professionals. ALICE was designed for Android and iOS to allow for the personalization of prescriptions and medical advice, showing images of each of the medications (the packaging and the medication itself) together with alerts and multiple reminders for each alert. The randomly assigned patients in the control group received oral and written information on the safe use of their medications and the patients in the experimental group used ALICE for 3 months. Pre and post measures included rate of missed doses and medication errors reported by patients, scores from the 4-item Morisky Medication Adherence Scale (MMAS-4), level of independence, self-perceived health status, and biochemical test results. In the experimental group, data were collected on their previous experience with information and communication technologies, their rating of ALICE, and their perception of the level of independence they had achieved. The intergroup intervention effects were calculated by univariate linear models and ANOVA, with the pre to post intervention differences as the dependent variables.

Results

Data were obtained from 99 patients (48 and 51 in the control and experimental groups, respectively). Patients in the experimental group obtained better MMAS-4 scores (P<.001) and reported fewer missed doses of medication (P=.02). ALICE only helped to significantly reduce medication errors in patients with an initially higher rate of errors (P<.001). Patients with no experience with information and communication technologies reported better adherence (P<.001), fewer missed doses (P<.001), and fewer medication errors (P=.02). The mean satisfaction score for ALICE was 8.5 out of 10. In all, 45 of 51 patients (88%) felt that ALICE improved their independence in managing their medications.

Conclusions

The ALICE app improves adherence, helps reduce rates of forgetting and of medication errors, and increases perceived independence in managing medication. Elderly patients with no previous experience with information and communication technologies are capable of effectively using an app designed to help them take their medicine more safely.

[Pharmaceutical prescription in primary care. SESPAS report 2012]

In 2010, the Spanish National Health Service (NHS) paid for 958 million prescriptions. Given the massive population exposure to medication, the risks associated with drug consumption are highly significant from the perspective of public health. Areas requiring improvement in primary care prescription include overtreatment of patients in low risk situations, undertreatment of those in whom medication is indicated, poor patient information, polymedication, self-medication and the appreciable percentage of preventable adverse effects. Surprisingly, most of the pharmaceutical strategies in the NHS have not aimed to address these problems but have instead concentrated on reducing pharmaceutical expenditure, which is not a problem of pharmaceutical expenditure per se but is rather a consequence of "the problems" of prescription (and of the regulation and management of pharmaceutical services). Some key elements to improve this situation include more integrated healthcare, the development of electronic medical records systems, overall strategies to improve safety, and reducing the role of the pharmaceutical industry. Macro strategies include creating an agency able to objectively assess the additional value provided by a new drug and its additional cost, price fixing in line with cost-effectiveness, and exclusion of drugs with little or no added value from coverage, etc. Managing prescription involves the development of longitudinal patient care programs that incorporate clinical actions from different professionals, including whom to treat, how much to treat and how to treat.

[Prevalence of multiple medication and cardiovascular risk in patients over 65 years]

OBJECTIVE

To describe the prevalence of multiple medication in patients over 65 years.

DESIGN

Cross-sectional study.

SETTING

Sevilla and Jerez-Costa North-West Primary Health Care Districts.

PARTICIPANTS

Patients older than 65 years randomly chosen from district databases. Patients in nursing homes, with major mental disease, or end-of- life situations were excluded.

MAIN MEASUREMENTS

Multiple medication was defined as a prescription of five or more drugs during the last six months. We assessed the medication used by clinical health records audit. Other characteristics were studied by interviewing a subsample of patients.

RESULTS

A total of 2,919 clinical health records from 14 centres were reviewed. The prevalence of multiple medication was 49.6% (95% CI: 47.7-51.4) with a range from 33% (95% CI: 26.8-39.3) to 82% (95% CI: 74,3-89,7) between centres. The large majority of patients (90.2% [95% CI: 88.7-91.8]) of patients showed criteria to be included in Cardiovascular Risk Health Care Process. Interviewed patients confirmed taking an average of 8.7 drugs (95% CI: 8.4-9.0). Among them, 83.2% (95% CI: 78.9-87.4) were high cardiovascular risk patients.

CONCLUSIONS

Prevalence of multiple medication in patients over 65 years is about 50% with wide variations between centres. The number of drugs per patient ratio was close to eight. A large majority of them were high risk cardiovascular patients.

[Validation of a questionnaire to assess patient knowledge of their medicines]

OBJECTIVE

Patient knowledge of their medicines is closely associated to a better rational use of drugs, thus achieving better health outcomes from their use. The objective of this study is to design and validate a questionnaire to assess the level of knowledge patients have about their medicines.

DESIGN

(A) Questionnaire: Literature review, some qualitative techniques (expert panel, brainstorming, Delphi method) and some pilot studies. (B) Questionnaire validation.

SETTING

A community pharmacy in the city of Malaga.

PARTICIPANTS

Patients attending the selected pharmacy, asking for at least one medicine.

MAIN MEASUREMENTS

The discriminant capacity of the items was assessed. Content and construct validity were analysed using the Spearman's Rho coefficient and Factor Analysis method. Reliability was assessed by measuring internal consistency, equivalence (inter-observer concordance) and test-retest reliability.

RESULTS

The final questionnaire, with 11 items explaining the different dimensions of knowledge found, was completed by 102 patients (a response rate of 95.3%) with a mean age of 46.6 years (SD 16.70). Mean time to complete it was 4.9 min (SD 2.2). Factor analysis showed a probable structure of 4 factors explaining the 67% of the total variance. The Spearman-Brown Rho coefficient was 0.30 (p<0.05). Cronbach alpha was 0.677, Kappa's coefficient=0.99 and intra-class correlation coefficient=0.745 (95% CI: 0.49-0.87).

CONCLUSIONS

The designed questionnaire is dynamic, valid and reliable, being able to measure the level of patient knowledge on the medicines they use.

[Self-medication and the elderly. The reality of the home medicine cabinet]

OBJECTIVE

To estimate the prevalence of self-medication in the elderly, to describe the characteristics of self-medication and home medicine cabinets.

DESIGN

Cross-sectional descriptive study.

SETTING

An urban primary health care (PHC) centre in Spain.

PARTICIPANTS

A total of 240 patients 75 years of age or older.

MAIN MEASUREMENTS

A structured questionnaire filled in by home care nurses from April to June 2006. Self-medication was classified into 4 sub-groups: pharmacological or herbal, exclusively pharmacological, exclusively herbal and pharmacological and herbal. The study variables were: age, sex, living alone, number of chronic diseases, number of chronic prescriptions and medicine cabinet characteristics (drugs accumulation, expired drugs, chronic drugs out of prescription, location of medicine chest and periodic review). Other variables were: drug types, source, and acute/chronic reason for self-medication.

RESULTS

Self-medication frequency was 31,2% (95% CI, 26-36), with 22.9% (95% CI, 17.5-27.5) being pharmacological and 15.4% (95% CI, 23.1-17.3), herbal. The drugs most used in self-medication were analgesics (30.9%) and cold remedies (27.2%). The pharmacy was the most usual source (49.3%). A total of 41.6% contained drugs that were out of chronic prescription, and 34.4% accumulated more than three boxes of the same medication.

CONCLUSIONS

There is a significant prevalence of self-medication among the elderly. Accumulating drugs in homes is a very extensive practice. Pharmacists and PHC professionals need to be trained in the responsible use of chronic and self-medication. Although self-care has to be encouraged, PHC professionals must make their patients aware of the harmful effects of self-medication.

[Study on the use of a smart pillbox to improve treatment compliance]

OBJECTIVE

To assess the usefulness of the Practidose individualised dispensing and dosing pillbox system in improving treatment compliance (TC).

DESIGN

Open-labelled, randomised, clinical trial.

SETTING

Cordoba province from April to September 2005.

PARTICIPANTS AND CONTEXT

A total of 220 patients 70 years diagnosed with ineffective management of treatment regime, polymedicated with no cognitive deterioration or limited mobility. Enrolment was carried out by block random assignment. Each district linking nurse was assigned 10 interviews, 5 from the intervention group and 5 from a control group.

INTERVENTION

To give a smart pillbox with instructions. MEASUREMENTS AND PRIMARY OUTCOMES: The response variable was the TC measured using the Morisky-Green questionnaire at the beginning and at 2 months. The independent variables were: age, sex, education level, number of people living in the home and mean age, diabetes, hypertension, heart disease, COPD, number of medications, number of daily and weekly doses self-medication, and interest in the patient information leaflet. A descriptive analysis and a multiple logistic regression were performed on the data. A total of 182 patients finished the study. The TC improved by 6.74% in the intervention group and by 2.15% in the control group. To look after the medications and suffer from COPD lead to better TC, and was less so when there was interest in the patient information leaflet.

CONCLUSIONS

The improvement in treatment compliance with the Practidose Pillbox was not statistically significant, although a positive tendency was observed.

[Frequency, relevance, causes of and strategies for prevention of medication errors]

Drug therapy has led to major advances in medicine. The beneficial effects of drug therapy are coupled with the inevitable risk of adverse drug reactions especially in elderly patients. Many adverse drug reactions are preventable. The electronic health card that will be introduced in Germany starting in 2006 is designed to support electronic decision support to prevent medication errors. Studies have demonstrated that CPOES can reduce medication errors by 80%. The necessary steps to improve medication safety in Germany are outlined and discussed.
