Patient involvement is essential in identifying drug-related problems

Managing drug therapy-related problems and assessment of chronic diabetic wounds

Type 2 diabetes mellitus (T2DM), responsible for most diabetes cases recorded worldwide, increases the risk of chronic wounds and amputation. Patients with T2DM appear to be more susceptible to delayed wound healing due to their treatment adherence. This review explores the specifics of polypharmacy, side effects, possible drug interactions and the importance of medication adherence for therapeutic efficacy. We discuss the effects of anti-diabetes medications on wound healing as well as the role that biofilms and microbial infections play in diabetic wounds. Inconsistent use of medications can lead to poor glycaemic control, which negatively affects the healing process of diabetic foot ulcers. Managing chronic wounds represents a substantial portion of healthcare expenditures. Biofilm-associated infections are difficult for the immune system to treat and respond inconsistently to antibiotics as these infections are slow growing and persistent. Additionally, we emphasize the critical role pharmacists play in enhancing patient adherence and optimizing diabetes treatment by offering comprehensive coverage of drugs associated with problems related to pharmacological therapy in type 2 diabetes.

Research status and hotspots of patient engagement: A bibliometric analysis

OBJECTIVE

This analysis aimed to examine current global trends in patient engagement research and identify critical focus areas.

METHODS

We searched the Web of Science Core Collection database for pertinent literature from January 1, 2000 to December 31, 2022. CiteSpace and VOSviewer were used for information analysis.

RESULTS

The bibliometric analysis covered 11,386 documents from 140 countries/regions, featuring contributions from 12,731 organizations and 45,489 authors. The United States and The University of Toronto were the most prolific country and institution. Leading researchers in publications and citations included Hibbard JH, Elwyn G, Legare F, and Street RL. Patient Education and Counseling led among journals.

CONCLUSION

Patient engagement research has experienced significant growth over the past two decades. The core of patient engagement research includes concepts, content, practical frameworks, impact assessment, and barriers. The current research focal points revolve around interventions for chronic disease patients, integrating digital health technologies to improve engagement, and incorporating patient-reported outcomes (PROs) into healthcare delivery.

PRACTICE IMPLICATIONS

This study unveils key trends and emphasizes global collaboration, strategic focus on chronic disease interventions, integration of digital health technologies, and the pivotal role of PROs. Embracing these insights promises to optimize healthcare practices and empower patients on a global scale.

A newly developed algorithm for switching outpatient medications to medications listed in the hospital formulary: a prospective real-word evaluation in patients admitted electively to hospital

PURPOSE

In many countries, outpatient and inpatient care are separated. During hospitalization, therefore, switching the outpatient medication to medication of the hospital formulary is required.

METHODS

We newly designed a switching algorithm in six switching steps (S0-S5) and conducted a study at Bundeswehr Hospital Hamburg (300 beds, 80% civilians). We performed (i) a medication reconciliation to obtain information on outpatient medications and (ii) a medication review to solve drug-related-problems, e.g., drug-drug interactions. We applied (iii) the algorithm to switch medications to the hospital formulary.

RESULTS

(i) We identified 475 outpatient medications (median per patient: 4; Q25/Q75 2/7) in 100 patients consecutively admitted to hospital (median age: 71; Q25/Q75: 64/80 years). Of 475 medications, the switching algorithm could not be used since product names were missing in 23.9% and strength in 1.7%. In 3.2%, switching was not required since medication was not prescribed during the hospital stay. (ii) Drug-drug interactions were identified in 31 of 79 patients with more than one medication. (iii) Of 475 medications, 18.5% were on the hospital formulary and therefore did not need to be  switched (S0), 0.2% were on a substitution-exclusion list not allowing switching (S1), 42.0% were switched to a generic medication of the hospital formulary (S2), 1.7% to a therapeutically equivalent medication (S3), 0.4% were patient-individually switched (S4), and for 8.2% a standardized/patient-individual switching was not possible (S5).

CONCLUSIONS

Despite comprehensive medication reconciliation, patient- and medication-related information for switching medications to the hospital formulary was often missing. Once all the necessary information was available, standardized switching could be easily carried out according to a newly developed switching algorithm.

Drug-Related Problems Detected in Complex Chronic Patients by Community Pharmacists of Catalonia: Perception of the Person-Centred Approach Necessity

Community pharmacies are healthcare settings in which pharmacists are in an ideal position to carry out pharmaceutical care. The aim of this study was to analyse the number, type and groups of drugs that caused drug-related problems (DRPs) detected in complex chronic patients who are outpatients, the interventions and actions of community pharmacists and their impact on patient medication adherence. The study was designed as a secondary analysis of a multicentre study in the field of primary healthcare and community pharmacies in Catalonia (Spain). The patients who took part were divided into two groups by the primary care physician depending on whether or not they were considered likely to receive their medication through a monitored dosage system (MDS) based on pre-established criteria. Patients underwent 12 months of follow-up by community pharmacists. The prevalence of DRPs among the studied complex chronic patients was high (n = 689). The most identified DRP was nonadherence (31.20%). In the MDS group, results showed a statistically significant increase of 21% in the number of adherent patients with respect to the baseline visit (p-value = 0.0008). Community pharmacists can have an important role in addressing DRPs and optimizing the safety and effectiveness of medications for these patients and in involving them in their own health conditions.

Pharmacist-Led Interventions to Reduce Drug-Related Problems in Prescribing for Pediatric Outpatients in a Developing Country: A Randomized Controlled Trial

OBJECTIVE

To evaluate a pharmacist-led intervention's effectiveness in reducing drug-related problems (DRPs ( related to prescriptions for pediatric outpatients.

METHODS

We conducted a randomized controlled trial. We recruited and randomly assigned 31 physicians to control or intervention groups. We collected 775 prescriptions (375 from the control group and 400 from the intervention group) at the start. For 3 weeks, intervention physicians received additional information and meetings with pharmacists in addition to the usual practices of the hospital. We then collected prescriptions at the end of the study. We classified DRPs, based on reliable references (Supplemental Table S1) at baseline and endpoint (a week after the intervention). The primary outcome was the proportion of prescriptions with DRPs, and secondary outcomes were the proportions of prescriptions with specific DRP types.

RESULTS

The influence of the intervention on general DRPs and specific DRPs was the study's main finding. The pharmacist-led intervention helped reduce the prescriptions with DRPs proportion in the intervention group to 41.0%, compared with 49.3% in the control group (p < 0.05). The DRPs proportion related to the timing of administration relative to meals, unlike the other DRP types, increased in the control group (from 31.7% to 34.9%) and decreased in the intervention group (from 31.3% to 25.3%), with a significant difference between the 2 groups at endpoint (p < 0.01). Patients aged >2 to ≤6 years (OR, 1.871; 95% CI, 1.340-2.613) and receiving ≥5 drugs (OR, 5.037; 95% CI, 2.472-10.261) were at greater risk of experiencing DRPs related to prescribing.

CONCLUSIONS

A pharmacist-led intervention improved DRP occurrence related to physicians' prescribing. Pharmacists could be involved in in-depth research with physicians in the prescribing process to provide tailored interventions.

Drug-related problems reported by patients with rheumatic diseases: an observational study

BACKGROUND

Drug-related problems can negatively influence treatment outcome and well-being for patients with rheumatic diseases. Thus, it is important to support patients in preventing or resolving drug-related problems as quickly as possible. To effectively develop interventions for this purpose, knowledge on the frequency and character of drug-related problems is needed. Therefore, this study aims to quantify and characterize drug-related problems reported by patients with inflammatory rheumatic diseases along their treatment process.

METHODS

A prospective observational study was conducted in a Dutch outpatient pharmacy. Adult patients with rheumatic diseases that were prescribed medication by a rheumatologist were questioned about experienced DRPs by telephone 4 times in 8 weeks using a structured interview-guide. Patient-reported DRPs were scored on uniqueness (i.e., if a specific DRP was reported in multiple interviews by one individual, this was counted as one unique DRP) and were categorized using a classification for patient-reported DRPs and analysed descriptively.

RESULTS

In total, 52 participants (median age 68 years (interquartile range (IQR) 62-74), 52% male) completed 192 interviews with 45 (87%) participants completing all 4 interviews. The majority of patients (65%) were diagnosed with rheumatoid arthritis. Patients reported a median number of 3 (IQR 2-5) unique DRPs during interview 1. In subsequent interviews, patients reported median numbers of 1 (IQR 0-2), 1 (IQR 0-2) and 0 (IQR 0-1) unique DRPs for interviews 2-4 respectively. Participants reported a median number of 5 (IQR 3-9) unique DRPs over all completed interviews. Unique patient-reported DRPs were most frequently categorized into (suspected) side effects (28%), medication management (e.g., medication administering or adherence) (26%), medication concerns (e.g., concerns regarding long-term side-effects or effectiveness) (19%) and medication effectiveness (17%).

CONCLUSIONS

Patients with rheumatic diseases report various unique DRPs with intervals as short as two weeks. These patients might therefore benefit from more continuous support in-between contact moments with their healthcare provider.

Patient experiences and opinions on medication review: a qualitative study

BACKGROUND

Medication reviews are a structured critical evaluation of a patient's pharmacotherapy, carried out by a healthcare professional, but are not yet a routine pharmaceutical service in Belgium. A pilot project to initiate an advanced medication review (= type 3 medication review) in community pharmacies was set up by the Royal Pharmacists' Association of Antwerp.

AIM

To investigate the experiences and opinions of patients who participated in this pilot project.

METHOD

Qualitative study through semi-structured interviews with participating patients.

RESULTS

Seventeen patients from six different pharmacies were interviewed. The medication review process with the pharmacist was perceived as positive and instructive by fifteen interviewees. The extra attention that the patient received was highly appreciated. However, the interviews revealed that patients did not fully understand the purpose and structure of this new service or were aware of the subsequent contact and feedback with the general practitioner. Medication reviews in the home setting put patients more at ease, were highly appreciated, and enabled also to address practical problems such as drug dosing or storage requirements.

CONCLUSION

This qualitative study analysed patients' experiences during a pilot project on the implementation of type 3 medication review. Although most patients were enthusiastic about this new service, a lack of patients' understanding of the whole process was also observed. Therefore, better communication to patients by pharmacists and general practitioners about the goals and components of this type of medication review is needed, with the added benefit of increased efficiency.

Why medicines are used differently from prescribed: a protocol for a prospective patient-oriented observational case study to investigate reasons for non-adherence in primary care

INTRODUCTION

Patients do not always tell the physician if they have used medicines differently from prescribed. The challenges that patients experience in medication self-management and adherence have been prioritised globally as among the most crucial factors influencing the effectiveness and safety of pharmacotherapies.

METHODS AND ANALYSIS

This study protocol presents a new patient-oriented method to investigate reasons for non-adherence using pharmacist-conducted medication reconciliation in a primary care clinic as data collection point. By interviewing, the pharmacist will learn how the patient has been taking the prescribed medicines and whether any non-prescription medicines and food supplements have been used for self-medication. The pharmacist will document the findings of the conversation to the electronic patient record in a structured format. The pharmacist will collect data related to the characteristics of the patients and outpatient clinics, patients' diseases and medications, and medication discrepancies. These data will be analysed for descriptive statistics to identify (1) the number of discrepancies between the physician's prescription orders and the patient's self-reported use of the medicines, (2) what kind of discrepancies there are, (3) which are high-risk medicines in terms of non-adherence and (4) why medicines were taken differently from prescribed; based on the results, (5) a preliminary conceptual model of patient-reported reasons for non-adherence will be constructed.

Prevalence and predictors of medication-related emergency department visit in older adults: A multicenter study linking national claim database and hospital medical records

Objectives: Older adults are more likely to experience drug-related problems (DRP), which could lead to medication-related emergency department visits (MRED). To properly evaluate MRED, the entire history of drug use should be evaluated in a structured manner. However, limited studies have identified MRED with complete prescription records. We aimed to evaluate the prevalence and risk factors of MRED among community-dwelling older patients by linking national claims data and electronic medical records using a standardized medication related admission identification method. Methods: We included older patients who visited the emergency departments of four participating hospitals in 2019. Among the 54,034 emergency department (ED) visitors, we randomly selected 6,000 patients and structurally reviewed their medical records using a standardized MRED identification method after linking national claims data and electronic medical records. We defined and categorized MRED as ED visits associated with adverse drug events and those caused by the underuse of medication, including treatment omission and noncompliance and assessed as having probable or higher causality. We assessed preventability using Schumock and Thornton criteria. Results: MRED was observed in 14.3% of ED visits, of which 76% were preventable. In addition, 32.5% of MRED cases were related to underuse or noncompliance, and the rest were related to adverse drug events. Use of antipsychotics, benzodiazepines, anticoagulants, traditional nonsteroidal anti-inflammatory drugs without the use of proton pump inhibitors, P2Y12 inhibitors, insulin, diuretics, and multiple strong anticholinergic drugs were identified as predictors of MRED. Conclusion: One in seven cases of ED visits by older adults were medication related and over three-quarters of them were preventable. These findings suggest that DRPs need to be systemically screened and intervened in older adults who visit ED.

Conceptualization and content validation of the MEDication literacy assessment of geriatric patients and informal caregivers (MED-fLAG)

Background

The assessment of patients’ medication literacy skills (i.e., abilities to access, comprehend and interact with medication-related information) is an important step in assisting clinicians to plan for appropriate care. Despite several attempts by researchers to develop measures of medication literacy, an instrument tailored to the specific needs of older adults remains a significant shortfall. Therefore, an interprofessional team that included a citizen co-researcher conceptualized a new standardised measure of medication literacy—the MEDedication Literacy Assessment of Geriatric patients and informal caregivers (MED-fLAG). MED-fLAG was designed as a three-dimensional self-reported measure of functional, interactive and critical skills. This study describes the conceptualization process and provides the results of an evaluation of MED-fLAG’s content validity, acceptability, and feasibility during a hospital stay.

Methods

MED-fLAG was developed in accordance with the guidance on scale development and standards for good content validity, by using the following steps: (I) conceptualization of a provisional version of MED-fLAG; (II) iterative qualitative evaluation of its content validity by older adults, informal caregivers and healthcare professionals.

Results

The qualitative assessment of the initial 54-item MED-fLAG was conducted in 36 participants, namely 13 home-dwelling older adults and/or informal caregivers and 23 healthcare professionals. Six rounds of revisions were performed to achieve content validity and to propose a 56-item revised MED-fLAG. Participants reported benefits of using a standardized assessment of medication literacy during a hospital stay but warned about certain limitations and prerequisites. The extent to which MED-fLAG could be integrated into discharge planning needs to be further investigated.

Conclusions

MED-fLAG is the first medication literacy measure tailored to the specific needs of older patients and informal caregivers. A unique feature of this measure is that it includes prescribed and non-prescribed medications, irrespective of the galenic form. Additional studies are required to evaluate the other measurement properties of MED-fLAG, and to reduce the number of items before considering its clinical application.

Supplementary Information

The online version contains supplementary material available at 10.1186/s41687-022-00495-2.

On the basis of what has been written about medication literacy and the experiences of experts, we developed a new questionnaire to measure medication literacy (MED-fLAG) in older adults and/or informal caregivers. MED-fLAG was then submitted to older adults, informal caregivers and healthcare professionals to retrieve their feedback concerning the relevance, comprehensibility and exhaustiveness of the proposed items. In future, MED-fLAG will allow health professionals to evaluate medication literacy skills in older patients during hospitalization and/or in their informal caregivers when they are responsible for preparing or administering the medications, and then propose individualised support.

Developing an interprofessional people-centred care model for home-living older people with multimorbidities in a primary care health centre: A community-based study

Background

The ageing population with multiple conditions and complex health needs has forced healthcare systems to rethink the optimal way of delivering services. Instead of trying to manage numerous diseases in a siloed approach, the emphasis should be on people-centred practice, in which healthcare services are tailored to people's needs and provided in partnership with them.

Objective

The aim was to develop an interprofessional people-centred care model (PCCM), including the contribution of a clinically trained pharmacist for home-living multimorbid older people in primary care.

Methods

Participatory action research method, including the active involvement of healthcare professionals, was utilised to develop the PCCM in a public health centre in Finland. The data comprised interview transcripts, workshop materials, field notes, surveys, and memos and were analysed using inductive content analysis.

Results

The PCCM was developed in iterative phases, including planning, acting, observing, and reflecting. The PCCM comprised: 1) A self-management evaluation questionnaire sent before a home visit; 2) A person-centred patient interview at home with a named nurse and a pharmacist; 3) A nurse-led health review and a pharmacist-led clinical medication review; 4) An interprofessional (a GP, a pharmacist and a named nurse) case conference meeting; 5) A care plan, including health and medication plans; and 6) Health support and empowerment interventions. The PCCM shifted working practices in the health centre from parallel and consultative practice towards interprofessional people-centred practice and more holistic care. The patient's active involvement in their own care was encouraged. Healthcare professionals appreciated the advantages of the new skill-mix, including the clinically trained pharmacist. Building trust among healthcare professionals and between the professionals and the patients was essential.

Conclusion

The successfully developed PCCM improved holistic and more people-centred care in primary care. Healthcare professionals appreciated the advantages of the skill mix and found that trust was essential for implementing the PCCM.

Integrating medication risk management interventions into regular automated dose dispensing service of older home care clients - a systems approach

BACKGROUND

Automated dose dispensing (ADD) services have been implemented in many health care systems internationally. However, the ADD service itself is a logistic process that requires integration with medication risk management interventions to ensure safe and appropriate medication use. National policies and regulations guiding ADD in Finland have recommended medication reconciliation, review, and follow-up for suitable risk management interventions. This implementation study aimed to develop a medication management process integrating these recommended risk management interventions into a regular ADD service for older home care clients.

METHODS

This study applied an action research method and was carried out in a home care setting, part of primary care in the City of Lahti, Finland. The systems-approach to risk management was applied as a theoretical framework.

RESULTS

The outcome of the systems-based development process was a comprehensive medication management procedure. The medication risk management interventions of medication reconciliation, review and follow-up were integrated into the medication management process while implementing the ADD service. The tasks and responsibilities of each health care professional involved in the care team became more explicitly defined, and available resources were utilized more effectively. In particular, the hospital pharmacists became members of the care team where collaboration between physicians, pharmacists, and nurses shifted from parallel working towards close collaboration. More efforts are needed to integrate community pharmacists into the care team.

CONCLUSION

The transition to the ADD service allows implementation of the effective medication risk management interventions within regular home care practice. These systemic defenses should be considered when national ADD guidelines are implemented locally. The same applies to situations in which public home care organizations responsible for services e.g., municipalities, purchase ADD services from private service providers.

Communication related to medication incidents-A concept analysis and literature review

AIMS

(1) To identify and analyse the conceptual framework and operationalise the concept of communication issues related to medication incidents in hospital to facilitate the development of a future tool for measuring frequencies of the communication issues. (2) To determine how the concept is distinct from related concepts.

DESIGN

Concept analysis.

DATA SOURCES

Twenty-three articles from seven scientific databases covering the years 2010-2020 and two official documents.

METHODS

Walker and Avant's concept analysis method was used. That was started by a systematised literature review on 2 November 2020 using specified criteria. Two authors evaluated articles' quality by Joanna Brigg's Institute's criteria. Literature review results were analysed deductive-inductively; conceptual framework was developed and concept defined presenting case scenarios. EQUATOR's standards were used in study reporting.

RESULTS

A conceptual framework and the concept of 'communication related to medication incidents in hospitals' were defined, comprising six main attribute categories: (1) communication dyads involved in communication, (2) patients' or professionals' individual issues, (3) institutional, (4) contextual and process issues, (5) communication concerning medication prescriptions and (6) qualitative characteristics of communication. The categories consisted of 128 quantitatively measurable and 10 qualitative attributes describing communication issues. The concept is distinct from related concepts by collating fragmented communication issues into the same concept.

CONCLUSION

The 128-item conceptual framework and the concept of communication related to medication incidents in hospitals were defined, as there was not one. The concept assembled parts of previous theories and fragmented information to one entity. The concept needs further condensing and validation to develop a tool for measuring communication issues.

IMPACT ON MEDICATION SAFETY

The conceptual framework can be used in practice and education as indicative rationale for reflection of current communication issues. The concept contributes to research by providing necessary grounding for tool development for measuring communication factors relating medication incidents.

Drug-Related Problems of Patients in Primary Health Care Institutions: A Systematic Review

Introduction: Drug-related problems (DRPs) are not only detrimental to patients' physical health and quality of life but also lead to a serious waste of health care resources. The condition of DRPs might be more severe for patients in primary health care institutions.

Objective: This systematic review aims to comprehensively review the characteristics of DRPs for patients in primary health care institutions, which might help find effective strategies to identify, prevent, and intervene with DRPs in the future.

Methods: We searched three English databases (Embase, The Cochrane Library, and PubMed) and four Chinese databases (CNKI, CBM, VIP, and Wanfang). Two of the researchers independently conducted literature screening, quality evaluation, and data extraction. Qualitative and quantitative methods were combined to analyze the data.

Results: From the 3,368 articles screened, 27 met the inclusion criteria and were included in this review. The median (inter-quartile range, IQR) of the incidences of DRPs was 70.04% (59%), and the median (IQR) of the average number of DRPs per patient was 3.4 (2.8). The most common type of DRPs was “treatment safety.” The causes of DRPs were mainly in the prescribing section, including “drug selection” and “dose selection”, while patients' poor adherence in the use section was also an important cause of DRPs. Risk factors such as the number of medicines, age, and disease condition were positively associated with the occurrence of DRPs. In addition, the medians (IQR) of the rate of accepted interventions, implemented interventions, and solved DRPs were 78.8% (22.3%), 64.15% (16.85%), and 76.99% (26.09%), respectively.

Conclusion: This systematic review showed that the condition of DRPs in primary health care institutions was serious. In pharmaceutical practice, the patients with risk factors of DRPs should be monitored more closely. Pharmacists could play important roles in the identification and intervention of DRPs, and more effective intervention strategies need to be established in the future.

Effectiveness and cost-effectiveness of a people-centred care model for community-living older people versus usual care ─ A randomised controlled trial

BACKGROUND

There is a need for effective and cost-effective interprofessional care models that support older people to maintain their quality of life (QoL) and physical performance to live longer independently in their own homes.

OBJECTIVES

The objectives were to evaluate effectiveness, QoL and physical performance, and cost-utility of a people-centred care model (PCCM), including the contribution of clinically trained pharmacists, compared with that of usual care in primary care.

METHODS

A randomised controlled trial (RCT) with a two-year follow-up was conducted. The participants were multimorbid community-living older people, aged ≥75 years. The intervention comprised an at-home patient interview, health review, pharmacist-led clinical medication review, an interprofessional team meeting, and nurse-led care coordination and health support. At the baseline and at the 1-year and 2-year follow-ups, QoL (SF-36, 36-Item Short-Form Health Survey) and physical performance (SPPB, Short Performance Physical Battery) were measured. Additionally, a physical dimension component summary in the SF-36 was calculated. The SF-36 data were transformed into SF-6D scores to calculate quality-adjusted life-years (QALYs). Healthcare resource use were collected and transformed into costs. A healthcare payer perspective was adopted. Incremental cost-effectiveness ratio (ICER) was calculated, and one-way sensitivity analysis was performed.

RESULTS

No statistically or clinically significant differences were observed between the usual care (n = 126) and intervention group (n = 151) patients in their QoL; at the 2-year follow-up the mean difference was -0.02, (95 % CI -0.07; 0.04,p = 0.56). While the mean difference between the groups in physical performance at the 2-year follow-up was -1.02, (-1.94;-0.10,p = 0.03), between the physical component summary scores it was -7.3, (-15.2; 0.6,p = 0.07). The ICER was -73 638€/QALY, hence, the developed PCCM dominated usual care, since it was more effective and less costly.

CONCLUSIONS

The cost-utility analysis showed that the PCCM including pharmacist-led medication review dominated usual care. However, it had no effect on QoL and the effect towards physical performance remained unclear.

Drug-Related Problems Identified During Pharmacy Intervention and Consultation: Implementation of an Intensive Care Unit Pharmaceutical Care Model

Aim

To identify common drug-related problems (DRPs) during pharmacy intervention and consultation in an intensive care unit (ICU); to explore the gap between physicians and pharmacists on their understanding of each other’s capabilities and needs.

Method

We conducted a single-center prospective study in the ICU of a tertiary academic hospital for 21 months. A pharmaceutical care (PC) model was implemented by a pharmacy team, and data were collected during pharmacy intervention and consultation. Data analysis was performed on identified DRPs, causes and their relationships. DRPs’ frequency during intervention and consultation was compared. Problem-level descriptive analysis and network analysis were conducted using R 3.6.3.

Result

Implementation of PC model greatly improved the efficacy of pharmacists in both interventions proposed to solve DRPs (from 13.6 to 20.1 cases per month) and number of patients being closely monitored (from 7.7 to 16.9 per month). Pharmacists identified 427 DRPs during pharmacy intervention with primarily adverse drug events (ADEs, 34.7%) and effect of treatment not optimal (25.5%), and 245 DRPs during consultation (mainly ADEs, 58.4%). About three-fifths DRPs were caused by antibiotics. Comparing DRPs identified during pharmacy intervention and consultation, physicians consulted pharmacists more on questions related to medication safety, while pharmacists also paid attention to treatment effectiveness, which was consulted less commonly.

Conclusion

Implementation of PC model is beneficial in guiding pharmacy practice and improving efficacy especially under limited human resources. Physicians and pharmacists shall continue ensuring drug safety and be familiar with the scope of PC and clinical need for a better cooperation.

Drug-related Problems in Home-dwelling Older Adults: A Systematic Review

PURPOSE

The complex combination of medicines associated with age-related physiological alterations leads older adults to experience drug-related problems (DRPs). The goal of this study was to review the frequency and type of DRPs and DRP risk factors in home-dwelling older adults.

METHODS

A MEDLINE PubMed and EMBASE scientific databases search was performed. Articles published from January 2000 through December 2018 reporting DRPs in home-dwelling older adults were included.

FINDINGS

From 668 articles screened, 13 met the inclusion criteria and were included in this study. Overall, the studies included 8935 home-dwelling patients. The mean number of DRPs per patient observed was 4.16 (1.37-10). The main causes of DRPs were "drug selection" (51.41%), "dose selection" (11.62%), and "patient related" (10.70%) problems. The drug classes more frequently associated with DRPs were "cardiovascular system," "alimentary tract and metabolism," and "nervous system," and they represented 32.1%, 29.4%, and 16.5% of all drug selection problems, respectively. Respiratory system medicines accounted for 6.65% of all DRPs, of which "patient related" problems accounted for 97.28%.

IMPLICATIONS

Despite the heterogeneity of methodology of the included studies and the heterogeneity of tools used to identify DRPs, this analysis clearly shows the high prevalence of DRPs in home-dwelling older adults and highlights the need for interventions to improve medicine use in this population. This work also provides useful information for the development of strategies to improve medication use in home-dwelling older adults.

Patients' and providers' perspectives on medication relatedness and potential preventability of hospital readmissions within 30 days of discharge

Background

Hospital readmissions are increasingly used as an indicator of quality in health care. One potential risk factor of readmissions is polypharmacy. No studies have explored the patients’ perspectives on the medication relatedness and potential preventability of their readmissions.

Objective

To compare the patients’ perspectives on the medication relatedness and potential preventability of their readmissions with the providers’ perspectives.

Methods

Patients unplanned readmitted within 30 days after discharge at one of the participating departments of OLVG Hospital in Amsterdam were interviewed during their readmission. Patients’ perspectives regarding medication relatedness of their readmissions, the potential preventability, possible preventable interventions, and satisfaction with medication information were examined. Health‐care providers also reviewed files of these readmitted patients. Primary outcome was the percentage of medication‐related and potentially preventable readmissions according to the patient vs the provider. Descriptive data analysis was used.

Results

According to patients, 36 of 172 (21%) readmissions were medication‐related, and of these, 21 (58%) were potentially preventable. According to providers, 26 (15%) readmissions were medication‐related and 6 (23%) of these were potentially preventable. Patients and providers agreed on the medication relatedness in 11 of the 172 readmissions, and in two of these, agreement on the potential preventability existed. According to patients, preventive interventions belonged mostly to the hospital level, followed by the primary care level and patient level.

Conclusion

Patients and providers differ substantially on their perspectives regarding the medication relatedness and preventability of readmissions. Patients were more likely to view medication‐related readmissions as preventable.

Cost-effectiveness of a clinical medication review in vulnerable older patients at hospital discharge, a randomized controlled trial

Background Drug-related problems (DRP) following hospital discharge may cause morbidity, mortality and hospital re-admissions. It is unclear whether a clinical medication review (CMR) and counseling at discharge is a cost-effective method to reduce DRP. Objective To assess the effect of a CMR on health care utilization and to investigate whether CMR is a cost-effective method to reduce DRP in older polypharmacy patients discharged from hospital. Setting 24 community pharmacies in the Netherlands. Method A cluster-randomized controlled trial with an economic evaluation. Community pharmacies were randomized to those providing a CMR, counseling and follow-up at discharge and those providing usual care. Main outcome measures Change in the number of DRP after 1 year of follow-up and costs of health care utilization during follow-up. In 216 patients the use of health care was prospectively assessed. Missing data on effects and costs were imputed using multiple imputation techniques. Bootstrapping techniques were used to estimate the uncertainty around the differences in costs and incremental cost-effectiveness ratios. Results CMR resulted in a small reduction of DRP. The proportion of patients readmitted to the hospital during 6 months of follow-up was significantly higher in the intervention group than in the control group (46.4 vs. 20.9%; p < 0.05). Health care costs were higher in the intervention group, although not statistically significant. The costs of reducing one DRP by a CMR amounted to €8270. Conclusion A CMR in vulnerable older patients at hospital discharge led to a small reduction in DRP. Because of a significantly higher use of health care and higher number of re-hospitalisations post CMR, the present study data indicate that performing the intervention in this patient population is not cost-effective.

Patient involvement is essential in identifying drug-related problems

AIMS

The aim of this study is to evaluate how critical patient involvement is in pharmacist-led clinical medication reviews and in identifying the most significant clinical drug-related problems (DRPs).

METHODS

Pharmacist-led clinical medication reviews were conducted with 161 consenting patients aged ≥75 years with at least seven prescribed medicines, living independently at home in Finland. A pharmacist, a nurse and a physician evaluated the clinical significance of the DRPs identified during the patient interview at an interprofessional case conference. It was evaluated whether the most significant clinical DRPs could also have been identified through reviewing the medication list only or the medication list and certain patient details.

RESULTS

Altogether, the 111 most significant clinical DRPs were evaluated. Only 6% could have been identified through reviewing the medication list only, and 16% through reviewing the medication list and certain patient details. Hence, 84% of the most significant clinical DRPs could only have been identified with patient involvement. The most common DRPs were: poor therapy control (25%); nonoptimal drug (22%); intentional nonadherence (12%); and additional drug needed (11%). patient involvement was critical when identifying DRPs related to additional drug needed, unintentional nonadherence, use of over-the-counter medicines or dietary supplements, or contradictions in counselling.

CONCLUSION

Patient involvement is essential when identifying clinical DRPs. Indeed, poor therapy control, nonoptimal drug use, intentional or unintentional nonadherence might otherwise be missed.
