Evaluating categorisation and clinical relevance of drug-related problems in medication reviews

Objectives We aimed to evaluate the categorisation and clinical relevance of DRPs identified by community pharmacists, and further, to assess the quality of interventions with the patients and the physicians as documented by the pharmacists. Setting 23 Norwegian community pharmacies. Method Patients with type 2 diabetes were recruited by 24 community pharmacists who performed structured medication reviews based on the patients’ drug profiles and patient interviews. The DRPs identified were subsequently categorised. An evaluation group (EG) retrospectively evaluated the reviews. Clinical/practical relevance of each DRP and quality of community pharmacists’ intervention with patients and physician were scored. Average agreement between the EG and the community pharmacists was calculated. Internal agreement in the EG was calculated using a modified version of Fleiss’ Kappa coefficient. Results A total of 73 patients were included (mean age 62 years, 52% female, on average prescribed 8.7 drugs). The pharmacists identified 88 DRPs in 43 of the patients. The most common DRPs were adverse drug reactions (22%) and wrong drug or dose used by patient (14%). Anti-diabetic drugs and lipid modifying drugs were associated with the most DRPs. The EG agreed with detection and categorisation of DRPs in more than 80% of the cases. The clinical/practical relevance of the detected DRPs was scored by the EG to be high or medium in 87% of the cases. The quality of the follow-up with patients and physicians was scored to be good or satisfactory in 93 and 98% of the cases, respectively. Conclusions Pre-defined categories of DRPs supported by structured forms were reliable and valid tools for identifying DRPs. The evaluation demonstrated that community pharmacists were able to identify DRPs of high to medium clinical/practical relevance, and to perform follow-ups of the DRPs with the patients and the physicians with a good or satisfactory quality.     

Development of an evidence-based checklist for the detection of drug related problems in type 2 diabetes

Objective To develop an evidence-based checklist to identify potential drug related problems (PDRP) in patients with type 2 diabetes. Setting The evidence based checklist was applied to records of ambulatory type 2 diabetes patients in New South Wales, Australia. Method After comprehensive review of the literature, relevant medication groups and potential drug related problems in type 2 diabetes were identified. All the relevant information was then structured in the form of a checklist. To test the utility of the evidence-based checklist a cross-sectional retrospective study was conducted. The PDRP checklist was applied to the data of 148 patients with established type 2 diabetes and poor glycaemic control. The range and extent of DRPs in this population were identified, which were categorized using the PCNE classification. In addition, the relationship between the total as well as each category of DRPs and several of the patients’ clinical parameters was investigated. Main outcome measure: Number and category of DRPs per patient. Results The PDRP checklist was successfully developed and consisted of six main sections. 682 potential DRPs were identified using the checklist, an average of 4.6 (SD = 1.7) per patient. Metabolic and blood pressure control in the study subjects was generally poor: with a mean HbA1c of 8.7% (SD = 1.5) and mean blood pressure of 139.8 mmHg (SD = 18.1)/81.7 mmHg (SD = 11.1). The majority of DRPs was recorded in the categories ‘therapy failure’ (n = 264) and ‘drug choice problem’ (n = 206). Potentially non-adherent patients had a significantly higher HbA1c than patients who adhered to therapy (HbA1c of 9.4% vs. 8.5%; P = 0.01). Conclusion This is the first tool developed specifically to detect potential DRPs in patients with type 2 diabetes. It was used to identify DRPs in a sample of type 2 diabetes patients and demonstrated the high prevalence of DRPs per patient. The checklist may assist pharmacists and other health care professionals to systematically identify issues in therapy and management of their type 2 diabetes patients and enable earlier intervention to improve metabolic control.     

Relationship between drug-related problems and health outcomes: a cross-sectional study among cardiovascular patients

Objective To describe drug-related problems (DRPs) and expense problems (EPs) identified by a standardised community pharmacist-based medication review (MR) program among Swiss cardiovascular outpatients (56–75 years old) and to evaluate the need for collaborative pharmacy practice to achieve economic, clinical and humanistic outcomes. Setting A pilot population of 85 cardiovascular outpatients who were customers of 14 community pharmacies (members of the pharmacieplus virtual chain) and insured with Groupe Mutuel health insurance. Method Cross-sectional study of a structured medication review program, conducted by 11 pharmacists in collaboration with 61 general practitioners (GPs), with patient interviews and access to medical data. Main outcome measure Numbers and types of DRPs and EPs within the study population and odds ratios between them, as well as economic, clinical and humanistic outcomes. Results Of the included patients, 91% had at least one DRP or EP. The odds ratios indicated that not being exposed to DRPs was associated with a higher chance of reaching the clinical target (OR: 3.4; IC95%:1.1–10.5; P = 0.01), of having a better physical quality of life than the median (OR: 2.5; IC95%:0.9–7.3; P = 0.05) and having lower total health care costs (OR: 3.2; IC95%:1.1–9.8; P = 0.02). Conclusions This cross-sectional study shows that the control of cardiovascular risk factors, quality of life and healthcare costs are statistically related to the presence of DRPs detected by a community pharmacist-based MR program.     

Pharmacists' performance of clinical interventions during adherence support medication reviews

BackgroundIn New Zealand, pharmacists are funded to provide adherence support to their patients via a service called “Medicines Use Review” (MUR). The service is based on the assumption that the medication regimen is clinically appropriate and therefore does not include a clinical review. However, whether or not pharmacists make clinical recommendations to patients during MUR is unclear.ObjectiveTo identify the types of drug-related problems (DRPs) and interventions provided during MUR in order to understand whether clinical interventions occur.MethodsA single district health board that funds MUR services was identified. The MUR providers that conducted MURs during the period (from 2007 – December 2011) were invited to participate. All MUR consultation records were reviewed and the data extracted were categorized according to the DRP Classification Scheme v6.2 by Pharmaceutical Care Network Europe (PCNE). DRPs that did not fit into the criteria were documented separately.ResultsConsultation records for 353 individual patients were obtained from five MUR providers. Of these patients, 56.4% were female and the median age was 73 years. A total of 886 DRPs were identified and resulted in a total of 844 interventions. During this period, 2718 medications were prescribed to these MUR patients. The most frequent DRPs identified were problems with “health literacy” and “non-adherence” to medications. However 18.1% (n = 160) of the DRPs were perceived as a clinical review that went beyond the practice of MUR. The most common intervention was “patient counselling” (20%), “compliance packaging provided” (16%) and “recommendation to change medication” (11%).ConclusionsIn this study, pharmacists perhaps based on ethical, legal and moral obligations provided clinical interventions that exceeded those expected and funded in a MUR. Since MUR detected a low number of clinical DRPs when compared to clinical medication review services conducted previously, a funding system that only supports MUR might not provide the important clinical support required by patients. Patients who receive only MUR may potentially be missing out on optimal care.     

Management of pharmacotherapy‐related problems in acute coronary syndrome: Role of clinical pharmacist in cardiac rehabilitation unit

Acute coronary syndrome (ACS) is one of the leading causes of mortality worldwide and negatively impacts healthcare costs, productivity and quality of life. Polymorbidity and polypharmacy predispose ACS patients to medication discrepancies between cardiologist‐prescribed medication and drug use by the patient, drug‐related problems (DRPs) and inadequate drug adherence. This study aimed to evaluate the impact of clinical pharmacist–provided services on the outcome of ACS patients. This was a prospective, randomized, controlled study on ACS patients participating in a cardiac rehabilitation programme. Forty ACS patients were randomly assigned to either control group, who received standard medical care, or intervention group, who received standard medical care plus clinical pharmacist–provided services. Services included DRP management, clinical assessment and enforcing the patient education and adherence. For both groups, the following were assessed at baseline and after 3 months: DRPs, adherence (assessed by 8‐item Morisky Adherence Questionnaire), patient's knowledge (assessed by Coronary Artery Disease Questionnaire), 36‐Short Form Health Survey (SF‐36), heart rate, systolic and diastolic blood pressure, low‐density lipoprotein (LDL), total cholesterol (TC) and fasting blood glucose (FBG). After 3 months, there was a significant difference between the intervention and control groups in the per cent change of DRPs (median: ?100 vs 5.882, P = 0.0001), patient's adherence score (median: 39.13 vs ?14.58, P = 0.0001), knowledge score (median: 30.28 vs ?5.196, P = 0.0001), SF‐36 scores, heart rate (mean: ?10.04 vs 6.791, P = 0.0001), diastolic blood pressure (mean: ?17.87 vs 10.45, P = 0.0001), systolic blood pressure (mean: ?16.22 vs 4.751, P = 0.0001), LDL (median: ?25.73 vs ?0.2538, P = 0.0071), TC (median: ?14.62 vs 4.123, P = 0.0005) and FBG (median: ?11.42 vs 5.422, P = 0.0098). Clinical pharmacists can play an important role as part of a cardiac rehabilitation team through patient education and interventions to minimize DRPs.     

Detection of drug related problems in an interdisciplinary health care model for rural areas in Germany

Objective The disparity between an increasing complexity of patients’ treatment and the declining number of general practitioners (GP) require action. The AGnES-concept (general practitioner-relieving, community-based, e-health assisted, systemic intervention) is based on the delegation of original physician-activities to qualified AGnES-practice assistants. Purposes of AGnES part 1 were to determine the feasibility of community-based home medication reviews (HMR) and the establishment of a health professional network to identify drug related problems (DRP) in the domicile of elderly patients. Two consecutive studies (AGNES 2 + 3) were conducted to implement HMR. Setting General practices on the isle of Rugia in Mecklenburg-Western Pomerania, a German rural area. Patients who receive regular home visits by their GP were addressed. Method Study-instruments for the feasibility study (AGnES 1) were designed by an expert panel and modified for the implementation (AGnES 2 + 3) studies. HMR were conducted by additionally qualified AGnES-practice assistants regarding DRP like drug–drug interaction (DDI), adverse drug reactions (ADR), and compliance. DRP-selection was inspired by the coding system Pi-Doc. Pharmacists checked DRP and intervened, if necessary. 18 (AGnES 1) and 60 (AGnES 2 + 3) geriatric patients received a minimum of two home visits by an AGnES-practice assistant. Main outcome measure Feasibility was assessed by patients’ satisfaction with care provided by the AGnES-practice assistant. For implementation reported DRP and the conducted interventions were evaluated. Results During AGnES 1 a documentation sheet was developed and tested. 56 potential DDI were identified. 37 of 112 drugs which caused potential interactions were attributed to OTC medication and food components. 84% of respondents judged the systematic evaluation of their pharmacotherapy as helpful. During AGnES 2 + 3 local pharmacists identified DDIs in 45% of patients. Seven patients (11.6%) reported at least one ADR attributable to their current medication. Those patients who received a second HMR (n = 29) during AGnES 2 + 3 rated the HMR as reasonable 65.5% (n = 19), and partly reasonable 24.1% (n = 7). Conclusions By comprehensive HMR conducted by AGnES-practice assistants in delegation of the patients’ GPs in cooperation with local pharmacists we could identify a considerable prevalence of DRP under real-life conditions. Further studies should recruit more participants including a control group with usual care.     

Characteristics of drug-related problems discussed by hospital pharmacists in multidisciplinary teams

Objective To investigate pharmacist contribution in the therapeutic hospital team by studying drug-related problems (DRPs), pharmacist therapy advice and consequences of the advice.Methods From May to December 2002, 827 patients in five Norwegian hospitals were included in the study. Demographic data, drugs used, relevant medical history, laboratory data and clinical/pharmacological risk factors were recorded prospectively at the wards.Main outcome measure DRPs, patients characteristics, pharmacist advice to physicians, nurses or patients, response to the pharmacist advice, and reasons (stated by the pharmacist) for not discussing an identified DRP, were reported. An independent quality assessment team retrospectively assessed the DRPs for a randomly selected number of the study population.Results On average 2.6 DRPs per patient were found. A total of 2128 DRPs were registered and of these 1583 (74%) DRPs were brought up for discussion. Physician immediate acceptance rates varied from 80% (for extremely important clinically signififcant DRPs) to 50% (for DRPs of minor clinical significance). High age, use of many drugs at admission, existence of many DRPs and many clinical/pharmacological risk factors for DRPs were associated with low immediate acceptance rate. Type of DRP influenced how the DRP was discussed; adverse drug reaction (ADR) and unnecessary drug were discussed with physicians while e.g. medical chart error and need for patient education were discussed with nurses/patients. Reasons for not discussing DRPs in the team were: not given priority (37%), no longer relevant (31%) and others (31%). DRPs of minor clinical significance were most often excluded from discussion (37%) as opposed to 14% and 22% of those of moderate and major clinical significance.Conclusions The majority of patients had one or more DRPs. The problems identified as DRPs by the pharmacists were accepted as such by the physicians and to a high degree acted upon. Both clinical significance of the DRP and patient characteristics influenced physician immediate acceptance rate. Some DRPs could be solved by direct contact with nurses or the patients. Awareness of DRPs increases through participation of pharmacists in the multidisciplinary therapeutic hospital team.     

GPs’ views on patient drug use and the pharmacist’s role in DRP management

Objective The aim of this study was to examine general practitioners’ (GPs’) views on (1) patients’ drug-related problems (DRPs) and noncompliance and (2) the role of pharmacy practitioners in DRP management. Method A brief questionnaire was designed and distributed to 224 GPs in Sweden. Results Totally 152 GPs responded (68%). Most felt that pharmacy practitioners could improve patients’ drug use by identifying DRPs. A majority of the GPs also found presentations and analyses of their local pharmacies’ DRP documentation valuable. According to the GPs’ experiences, adverse drug effects and therapy failure were the most salient problems in patients’ drug use. Half of the doctors believed that 50–75% of their patients were compliant with their prescribed drug treatments. A majority of the GPs found a 75–95% degree of compliance acceptable. Conclusion The surveyed GPs demonstrated very positive attitudes towards the role of pharmacy practitioners in improving patients’ drug use and managing DRPs. The GPs realised that many patients were not compliant with their prescribed drug treatments and accepted an imperfect compliance.     

Pharmacist-led medication reviews in pre-dialysis and dialysis patients

BackgroundPre-dialysis and dialysis patients are at risk for drug related problems (DRPs) due to a high incidence of comorbidities. Pharmacist-led medication reviews might reduce the number of DRPs.ObjectivesThe aim of this study was to evaluate pharmacist-led medication reviews in pre-dialysis and dialysis patients by determining the number and type of DRPs, nephrologist acceptance of pharmacist interventions and time investment.MethodsFrom September 2017 until December 2018, pharmacist-led medication reviews were performed on pre-dialysis and dialysis patients. DRPs (medication discrepancies, prescribing issues related to drug and dose selection, drug use problems) were identified using the pharmacists’ expert opinion and the STOPP/START criteria. Number and type of accepted pharmacist interventions, sustainability of interventions after at least 1 month and time investment were determined. Practical barriers in the process were appraised.ResultsOne-hundred twenty five patients were reviewed: 37 pre-dialysis and 88 dialysis patients. In 100 (80%) patients 277 medication discrepancies were identified of which 224 (81%) were accepted by the nephrologist. Pharmacists suggested 422 interventions concerning drug or dose selection for 115 patients; 106 interventions were accepted by the nephrologist, which resulted in 60 patients having medication changed. Ninety percent of those changes remained implemented on follow-up after at least 1 month. In 46 (37%) patients, the clinical pharmacist detected DRPs concerning the drug use process and performed patient counseling. The average time investment was 85 min per patient for the clinical pharmacist and 15 min for the nephrologist. Besides time investment, unclear responsibility for medication management due to multiple prescribers was an important barrier in the process and the main reason for nephrologists to reject pharmacist interventions.ConclusionPharmacist-led medication reviews in pre-dialysis and dialysis patients led to medication changes in half of the patients. However, efficiency should be improved before adopting pharmacist-led medication reviews into clinical practice.     

Drug-related problems and satisfaction among patients receiving pharmacist-led consultations at the initiation of cardiovascular drugs

BackgroundDrug-related problems (DRPs) lead to substantial morbidity and mortality and increase healthcare costs. Several interventions have been developed to reduce DRPs and improve the outcome of drug therapy.ObjectiveTo investigate DRPs identified through a pharmacist-led intervention and to assess patient satisfaction with the intervention.MethodsPatients received two pharmacist consultations 1–2 weeks and 3–5 weeks after collecting a new cardiovascular medicine. Information about patient characteristics, beliefs about medicines (BMQ), DRPs, and patient evaluations were collected using questionnaires.ResultsPharmacists identified DRPs among 52.4% and 43.1% of the 633 patients at consultation 1 and 2, respectively. Of the DRPs reported in consultation 1, 43.7% were solved at consultation 2. Among patients with side effects, patients who received advice on managing these in consultation 1 where more likely to have solved problems at consultation 2 (61.2% vs. 42.6%, p = 0.008). Female gender, high BMQ concern and the number of new medicines were associated with DRPs. Patients were highly satisfied with the intervention. Predictors of satisfaction were female gender, older age, higher BMQ necessity, face-to-face consultations, longer duration of consultation 1, and solved problems in consultation 2.ConclusionsThe results indicate that the pharmacist-led follow-up intervention can aid early identification and solving of DRPs in patients prescribed new cardiovascular drugs. Knowledge of factors associated with DRPs and patients’ satisfaction may allow further improvement of the intervention.     

Effects of home medication review on drug-related problems and health-related quality of life among community-dwelling older adults in China

BackgroundThere is a lack of research on the nature of drug-related problems (DRPs) in older adult communities in China and the impact of home medication review on DRP reduction and health-related quality-of-life (HRQoL) improvement.ObjectivesTo identify and categorize DRPs in older adults in China and to assess the impact of home medication review.MethodsThe prospective study was conducted in 2 community health service centers in Shanghai, China from December 2018 to December 2019. Eligible patients received a home medication review by a clinical pharmacist to assess for DRPs and adherence, propose pharmaceutical interventions, and measure outcomes of HRQoL. All enrolled patients were followed up for 3 months.ResultsMedication use in 412 patients was analyzed. A total of 362 DRPs were identified, an average of 0.88 per patient. Treatment effectiveness was the primary DRP type (249; 68.8%). The most common causes of DRPs were patient-related (35.1%) and drug selection (31.0%). Pharmacists made 733 interventions, an average of 2 per DRP. A total of 82.1% of these interventions were accepted. At a 3-month follow-up, home medication review led to a statistically significant reduction in the mean number of DRPs (0.4 vs. 0.88, P < 0.001) and an increase in medication adherence (1.42 vs. 0.85, P < 0.001). Both HRQoL indicators also improved, EuroQol 5 Dimension scale (0.75 vs. 0.78, P < 0.001) and EuroQol–visual analog scale (70 vs. 77.65, P < 0.001).ConclusionHome medication review is a practical means to optimize drug therapy and improve patients’ HRQoL in community settings.
