Development of an evaluation system for rational drug use in patients with chronic kidney disease using the Delphi method

Background

Chronic kidney disease (CKD) stages 3-4 present a significant clinical challenge due to the absence of a systematic approach to managing associated medication-related problems (MRPs). This lack of a structured framework hinders the timely identification and effective intervention for these complications, potentially compromising patient safety and prognosis.

Objective

This study aims to leverage the Delphi method to establish an evaluation index for a rational drug use evaluation system dedicated to CKD patients in stages 3-4. This system will function as a platform for the continuous identification and management of MRPs, ultimately contributing to improved medication safety and patient outcomes.

Methods

This research uses the modified Delphi technique to develop an evaluation system for rational drug use in patients with chronic kidney disease. The initial questionnaire was developed by literature review for patients with chronic kidney disease. Twenty-six senior experts formed a panel in order to evaluate items across two Delphi rounds. Consensus was defined as at least 95% agreement (first round) and 85% agreement (second round), agreeing with an average score of at least 4.5 (first round) and 4.0 (second round). Items that fulfill the stipulated criteria are eligible for inclusion in the consensus list.

Results

All experts participated in both rounds (100% response rate). Consensus was achieved on three patient-related items in the first round of 34 items. Based on expert feedback, 18 revised items were included in the second round after refining, restructuring, and removing some elements. Following two rounds of consultation, 20 items achieved consensus, encompassing aspects such as drug selection, dosage assessment, treatment duration, prescription and dispensing practices, patient-related factors, and other relevant considerations.

Conclusion

This study has successfully identified 20 key evaluation indicators for a rational drug use evaluation system specifically designed for CKD patients in stages 3 and 4. This system will serve as a tool for continuous MRP identification and timely intervention, ultimately enhancing medication safety and patient prognosis.

Screening, identifying, and treating chronic kidney disease: why, who, when, how, and what?

1 in 7 American adults have chronic kidney disease (CKD); a disease that increases risk for CKD progression, cardiovascular events, and mortality. Currently, the US Preventative Services Task Force does not have a screening recommendation, though evidence suggests that screening can prevent progression and is cost-effective. Populations at risk for CKD, such as those with hypertension, diabetes, and age greater than 50 years should be targeted for screening. CKD is diagnosed and risk stratified with estimated glomerular filtration rate utilizing serum creatinine and measuring urine albumin-to-creatinine ratio. Once identified, CKD is staged according to C-G-A classification, and managed with lifestyle modification, interdisciplinary care and the recently expanding repertoire of pharmacotherapy which includes angiotensin converting enzyme inhibitors or angiotensin-II receptor blockers, sodium-glucose-cotransporter-2 inhibitors, and mineralocorticorticoid receptor antagonists. In this paper, we present the why, who, when, how, and what of CKD screening.

Medicines optimization for patients with chronic kidney disease in the outpatient setting: the role of the clinical pharmacist

OBJECTIVES

Medicines optimization (MO) in patients with chronic kidney disease (CKD) is at high risk at transition points of different ambulatory care levels such as nephrologists in outpatient clinics and general practitioners (GPs). We examined if adding a clinical pharmacist to the therapeutic team promotes implementation of nephrologists' drug therapy recommendations by GPs' and reduces drug-related problems (DRPs).

METHODS

A prospective, controlled intervention study was conducted in the nephrology outpatient clinic of the Klinikum Fulda, Germany. The control and intervention phases took place successively. Patients with CKD stage 3-5 and at least one concomitant disease, for example, arterial hypertension or type-2 diabetes were recruited consecutively in three subgroups (naive, 1 contact, ≥2 contacts with nephrologist) from June 2015 to May 2019. GPs' acceptance and frequency of DRPs without (control group [CG]) and with (intervention group [IG]) pharmacist's interventions were compared after 6 months. Interventions include educational training events for GPs between control- and intervention phase, medication therapy management and pharmaceutical patient counselling.

KEY FINDINGS

In total, 256 patients (CG = 160, IG = 96) were recruited into the study. GPs' acceptance of nephrologists' medication recommendations increased significantly among naive patients and those with one prior contact with the nephrologist (CG/IG: naive = 72.8%/95.5%, 1 contact = 81.1%/94.4%; P < 0.001). DRPs per patient were significantly reduced in all subgroups (P < 0.001).

CONCLUSIONS

Interdisciplinary collaboration between the nephrologist, GPs and clinical pharmacist resulted in better MO for patients with CKD.

The Role of Community Pharmacists in the Detection of Clinically Relevant Drug-Related Problems in Chronic Kidney Disease Patients

Community pharmacists (CPs) have traditionally had limited access to patients’ estimated glomerular filtration rate (eGFR) during the medication-dispensing process. The increasing access to shared electronic health records is making eGFR available, but the skills needed to detect and manage clinically relevant drug-related problems (DRPs) are poorly documented. The primary objective of this study was to investigate the role of CPs in the medication-dispensation process for elderly patients with renal impairment. A total of 70 CPs participated in this 6 month study. Community pharmacists asked all patients ≥65 years to bring their laboratory test values for the next medication-dispensing process. Drug-related problem detection rates were compared between CPs (prospective period) and expert pharmacists (retrospectively). The clinical relevance of each DRP was assessed by nephrologists and general practitioners using an appropriate tool. Community pharmacists recruited n = 442 patients with eGFR < 60 mL/min/1.73 m² and detected n = 99 DRPs, whereas expert pharmacists detected n = 184 DRPs. The most frequently detected DRPs were dosage problems and contraindications. According to assessment by clinicians, CPs and expert pharmacists identified 54.0% and 84.7% of clinically relevant DRPs, respectively. This study suggests a positive impact of the systematic availability of eGFR to CPs on the detection of several DRPs with clinical relevance.

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

BACKGROUND

Pre-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.

OBJECTIVES

The 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.

METHODS

From 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.

RESULTS

One-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.

CONCLUSION

Pharmacist-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.

Do pharmacy intervention reports adequately describe their interventions? A template for intervention description and replication analysis of reports included in a systematic review

INTRODUCTION

Scientific progress and translation of evidence into practice is impeded by poorly described interventions. The Template for Intervention Description and Replication (TIDieR) was developed to specify the minimal intervention elements that should be reported.

OBJECTIVES

(1) To assess the extent to which outpatient pharmacy interventions were adequately reported. (2) To examine the dimension(s) across which reporting quality varies. (3) To examine trial characteristics that predict better reporting.

METHODS

The sample comprised 86 randomised controlled trials identified in a Cochrane review of the effectiveness of pharmacist interventions on patient health outcomes. Duplicate, independent application of a modified 15-item TIDieR checklist was undertaken to assess the intervention reporting. The reporting/non-reporting of TIDieR items was analysed with principal component analysis to evaluate the dimensionality of reporting quality and regression analyses to assess predictors of reporting quality RESULTS: In total, 422 (40%) TIDieR items were fully reported, 395 (38%) were partially reported and 231 (22%) were not reported. A further 242 items were deemed not applicable to the specific trials. Reporting quality loaded on one component which accounted for 26% of the variance in TIDieR scores. More recent trials reported a slightly greater number of TIDieR items (0.07 (95% CI 0.02 to 0.13) additional TIDieR items per year of publication). Trials reported an 0.09 (95% CI 0.04 to 0.14) additional TIDieR items per unit increase in impact factor (IF) of the journal in which the main report was published.

CONCLUSIONS

Most trials lacked adequate intervention reporting. This diminished the applied and scientific value of their research. The standard of intervention reporting is, however, gradually increasing and appears somewhat better in journals with higher IFs. The use of the TIDieR checklist to improve reporting could enhance the utility and replicability of trials, and reduce research waste.

Clinical pharmacy practice in the care of Chronic Kidney Disease patients: a systematic review

Background Clinical pharmacy services have potential to contribute significantly to the multidisciplinary team providing safe, effective and economic care for patients. Given recent practice developments (e.g. polypharmacy reviews and pharmacist prescribing) there is a need to provide a current synthesis of the evidence base for characteristics and outcomes of clinical pharmacy practice in chronic kidney disease patients. Aim of the review To critically appraise, synthesise and present the available evidence of the characteristics (structures and processes) and outcomes of clinical pharmacy practice as part of the multidisciplinary care of patients with chronic kidney disease. Method PubMed, International Pharmaceutical Abstracts (IPA), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline and Scopus were searched for peer reviewed papers using improved search strategy. Included studies were quality assessed using Downs and Black tool for controlled studies and the mixed methods appraisal tool for all controlled and non-controlled studies. Data were extracted and synthesised using a narrative approach. Screening, quality assessment and data extraction were performed by two independent researchers. Ethics approval was not required. Results Forty-seven studies were identified from a variety of countries, with 31 based in a hospital setting. Controlled study designs were employed in 20, with only ten of these using randomisation. Resources available for service provision were poorly reported in all papers. Positive impact on clinical outcomes included significant improvement in parathyroid hormone, blood pressure, haemoglobin and creatinine clearance. Pharmacists identified 5302 drug related problems in 2933 patients and made 3160 recommendations with acceptance rates up to 95%. Impact on humanistic outcomes was shown through improvement in health related quality of life and patient satisfaction. Economic benefits arose from significant cost savings through pharmaceutical care provision. Conclusion While there is some evidence of positive impact on clinical, humanistic and economic outcomes, this evidence is generally of low quality and insufficient volume. While the existing evidence is in favour of pharmacists' involvement in the multidisciplinary team providing care to patients with chronic kidney disease, more high-quality research is warranted.

Models of care for chronic kidney disease: A systematic review

AIM

Chronic kidney disease (CKD) is common and presents an increasing burden to patients and health services. However, the optimal model of care for patients with CKD is unclear. We systematically reviewed the clinical effectiveness of different models of care for the management of CKD.

METHODS

A comprehensive search of eight databases was undertaken for articles published from 1992 to 2016. We included randomized controlled trials that assessed any model of care in the management of adults with pre-dialysis CKD, reporting renal, cardiovascular, mortality and other outcomes. Data extraction and quality assessment was carried out independently by two authors.

RESULTS

Results were summarized narratively. Nine articles (seven studies) were included. Four models of care were identified: nurse-led, multidisciplinary specialist team, pharmacist-led and self-management. Nurse and pharmacist-led care reported improved rates of prescribing of drugs relevant to CKD. Heterogeneity was high between studies and all studies were at high risk of bias. Nurse-led care and multidisciplinary specialist care were associated with small improvements in blood pressure control.

CONCLUSION

Evidence of long term improvements in renal, cardiovascular or mortality endpoints was limited by short follow up. We found little published evidence about the effectiveness of different models of care to guide best practice for service design, although there was some evidence that models of care where health professionals deliver care according to a structured protocol or guideline may improve adherence to treatment targets.

Development of intervention-related quality indicators for renal clinical pharmacists using a modified Delphi approach

OBJECTIVE

To develop a list of renal Quality Indicator Drug therapy problems (QI-DTPs) that serve to advance renal pharmacy practice to improve patient care.

METHODS

Eighteen (18) renal, clinical pharmacists participated in an internet-based three-round modified Delphi survey. Each of the three rounds took approximately 2 weeks to complete. Panellists rated 30-candidate renal QI-DTPs using seven selection criteria and one overall consensus criterion on a nine-point Likert scale. Consensus was reached if 75% or more of panellists assigned a score of 7-9 on the consensus criterion during the third Delphi round.

KEY FINDINGS

All panellists completed three rounds of Delphi survey. Seventeen-candidate renal QI-DTPs met the consensus definition.

CONCLUSIONS

A Delphi panel of renal clinical pharmacists successfully identified 17 consensus renal QI-DTPs. Assessment and implementation of these QI-DTPs will serve to advance renal pharmacy practice and improve patient care.

Prevalence and Management of Drug-Related Problems in Chronic Kidney Disease Patients by Severity Level: A Subanalysis of a Cluster Randomized Controlled Trial in Community Pharmacies

BACKGROUND

Drug-related problems (DRPs) are prevalent among chronic kidney disease (CKD) patients. However, little is known about their severity and management by community pharmacists.

OBJECTIVES

To (a) describe the prevalence of DRPs by severity level in CKD patients and (b) assess the effect of a training-and-communication network program in nephrology (ProFiL) on these DRPs.

METHODS

This is a secondary analysis of a cluster randomized controlled trial evaluating the effect of the ProFiL-program. In 6 CKD clinics, patients at CKD stage 3 or 4 and their community pharmacists were recruited and assigned to the ProFiL group or a usual care (UC) group. Using validated criteria, 2 pharmacists identified DRPs and assessed their severity at baseline and after 12 months. The mean annual change in the number of DRPs per patient by severity level was assessed using a 2-level multivariable linear mixed-effects model.

RESULTS

A total of 494 pharmacists and 442 patients participated. At baseline, the prevalence (mean number of DRPs per patient [SD]) of mild DRPs (e.g., requiring dosage adjustment) and moderate DRPs (e.g., drug adherence requiring a monitoring plan) were 0.55 (0.98) and 1.04 (1.51), respectively. After 12 months, an unadjusted incremental annual reduction of 0.34 moderate DRPs (95% CI = -0.66 to -0.01) was observed in the ProFiL group compared with the UC group. After adjustment, no between-group differences were observed.

CONCLUSIONS

Among patients followed in CKD clinics, most DRPs have a moderate severity requiring specific monitoring by pharmacists. The benefit of continuing education programs, such as ProFiL, to reduce moderate DRPs remains to be determined.

Pharmacist-led discharge medication counselling: A scoping review

RATIONALE, AIMS, AND OBJECTIVES

Discharge medication counselling has produced improved quality of care and health outcomes, especially by reducing medication errors and readmission rates, and improving medication adherence. However, no studies have assembled an evidence-based discharge counselling process for clinical pharmacists. Thus, the present study aims to map the components of the pharmacist-led discharge medication counselling process.

METHODS

We performed a scoping review by searching electronic databases (Pubmed, Scopus, and DOAJ) and conducting a manual search to identify studies published up to July 2017. Studies that addressed pharmacist-led discharge medication counselling, regardless of the population, clinical conditions, and outcomes evaluated, were included.

RESULTS

A total of 1563 studies were retrieved, with 75 matching the inclusion criteria. Thirty-two different components were identified, and the most prevalent were the indication of the medications and adverse drug reactions, which were reported in more than 50% of the studies. The components were reported similarly by studies from the USA and the rest of the world, and over the years. However, 2 differences were identified: the use of a dosage schedule, which was more frequent in studies published in 2011 or before and in studies outside the USA; and the teach-back technique, which was used more frequently in the USA. Poor quality reporting was also observed, especially regarding the duration of the counselling, the number of patients, and the medical condition.

CONCLUSION

Mapping the components of the pharmacist-led discharge counselling studies through a scoping review allowed us to reveal how this service is performed around the world. Wide variability in this process and poor reporting were identified. Future studies are needed to define the core outcome set of this clinical pharmacy service to allow the generation of robust evidence and reproducibility in clinical practice.

Characterization of pharmacists' interventions in asthma management: A systematic review

OBJECTIVE

Pharmacists have adopted an active role in asthma management. This review aimed to analyze the intervention dose, understood as the "amount of program delivered," and core components of the intervention provided by pharmacists in asthma management.

DATA SOURCES

A literature search was conducted in December 2016 using PubMed.

STUDY SELECTION

A 2-stage approach was used. At the first stage, systematic reviews of pharmacists' interventions in asthma management were identified. At the second stage, primary studies included in the systematic reviews were selected.

DATA EXTRACTION

The DEPICT-2 (Descriptive Elements of Pharmacist Intervention Characterization Tool) was used for data extraction. In addition GINA (Global Initiative for Asthma) guidelines were used as a reference to classify the interventions' core components.

RESULTS

Thirty-one studies were included. In most of the studies, the pharmacist-patient intervention occurred at the community pharmacy setting (n = 22). The most common core components used in pharmacists' interventions were the provision of drug information and patient counseling (n = 27). Pharmacists' interventions frequently were targeted at assessing and improving the use of patient's inhaler technique (n = 27). Educational materials and written action plans were the materials most commonly used in the interventions (n = 20). The duration (n = 13) and the frequency (n = 16) of the intervention were the most frequent information about the intervention dose measure reported.

CONCLUSION

Pharmacists' interventions in asthma management are complex. Structured educational programs and patient counseling appear to be the most frequent core components of pharmacists' interventions. Interventions were focused on providing information about the condition and on inhaler technique assessment and training. However, most studies failed to report the intervention dose sufficiently to be reproduced. The reporting of this indicator is crucial to ensure the reproducibility of the interventions assessed and their implementation in practice. (Registration number CRD42016029181.).

A Systematic Review of Evidence-Based Community Pharmacy Services Aimed at the Prevention of Cardiovascular Disease

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death worldwide and has a substantial impact on people's health and quality of life. CVD also causes an increased use of health care resources and services, representing a significant proportion of health care expenditure. Integrating evidence-based community pharmacy services is seen as an asset to reduce the burden of CVD on individuals and the health care system.

OBJECTIVES

To (a) identify community pharmacy evidence-based services designed to help prevent CVD and (b) provide fundamental information that is needed to assess their potential adaptation to other community pharmacy settings.

METHODS

This review used the DEPICT database, which includes 488 randomized controlled trials (RCT) that address the evaluation of pharmacy services. Articles reviewing these RCTs were identified for the DEPICT database through a systematic search of the following databases: MEDLINE, Scopus, SciELO (Scientific Electronic Library Online), and DOAJ (Directory of Open Access Journals). The DEPICT database was reviewed to identify evidence-based services delivered in the community pharmacy setting with the purpose of preventing CVD. An evidence-based service was defined as a service that has been shown to have a positive effect (compared with usual care) in a high-quality RCT. From each evidence-based service, fundamental information was retrieved to facilitate adaptation to other community pharmacy settings.

RESULTS

From the DEPICT database, 14 evidence-based community pharmacy services that addressed the prevention of CVD were identified. All services, except 1, targeted populations with a mean age above 60 years. Pharmacy services encompassed a wide range of practical applications or techniques that can be classified into 3 groups: activities directed at patients, activities directed at health care professionals, and assessments to gather patient-related information in order to support the previous activities.

CONCLUSIONS

This review provides pharmacy service planners and policymakers with a comprehensive list of evidence-based services that have the potential to be adapted to different settings from which they were originally implemented and evaluated in order to reduce the burden of CVD.

DISCLOSURES

Funding for this review was provided by the University of Technology Sydney Chancellor's Postdoctoral Fellowship awarded to Sabater-Hernández. No other potential conflict of interest was declared. Study concept and design were contributed by Sabater-Hernández, Fernandez-Llimos, Rotta, and Correr. Sabater-Galindo and Sabater-Hernández took the lead in data collection, along with Franco-Trigo and Rotta. Data interpretation was performed by Sabater-Hernández, Durks, and Lopes. The manuscript was written primarily by Sabater-Hernández, along with Hossain, and revised by Fernandez-Llimos, Rotta, and Benrimoj, with assistance from Durks, Sabater-Galindo, Franco-Trigo, and Correr.

Investigating Sources of Heterogeneity in Randomized Controlled Trials of the Effects of Pharmacist Interventions on Glycemic Control in Type 2 Diabetic Patients: A Systematic Review and Meta-Analysis

OBJECTIVE

To assess the effect of pharmacist interventions on glycemic control in type 2 diabetic patients and to examine factors that could explain the variation across studies.

METHODS

A comprehensive literature search was performed in PubMed, Scopus, and LILACS databases for randomized controlled trials (RCTs) published up to July 2015. The search strategy included the use of MeSH terms or text words related to pharmacist interventions, type 2 diabetes, and randomized controlled trials. RCTs published in English, Portuguese, or Spanish that evaluated the effect of pharmacist intervention on glycemic control in type 2 diabetic outpatients were included. Two independent authors executed study selection, data extraction, and risk of bias assessment. Mean differences in glycosylated hemoglobin (HbA1c) were estimated using random-effect models, and heterogeneity was evaluated by subgroup and meta-regression analyses.

RESULTS

The literature search yielded 963 records of potential interest, of which 30 were included in the systematic review and 22 in the meta-analysis. Most of these RCTs were conducted in the United States in patients in outpatient clinics using face-to-face contact only. All RCTs performed patient education, and most executed the medication review. The appraised sample showed uncertain or high risk of bias in most of the items evaluated, resulting in low-quality studies. In comparison with usual care, pharmacist interventions were associated with significant reductions in HbA1c levels (-8.5% [95% CI: -1.06, -0.65]; P < 0.0001; I2 = 67.3%). Subgroup analysis indicated differences of heterogeneity by country, baseline HbA1c levels, setting, intervention frequency, and random allocation. Age and HbA1c levels partly explained the variability across studies by meta-regression.

CONCLUSIONS

Our findings confirmed that pharmacist interventions improve glycemic control in patients with type 2 diabetes compared with usual care and suggest that younger patients or with higher baseline HbA1c levels may be the main beneficiaries of pharmacist care.

Ensuring consistent reporting of clinical pharmacy services to enhance reproducibility in practice: an improved version of DEPICT

RATIONALE, AIMS AND OBJECTIVES

DEPICT (Descriptive Elements of Pharmacist Intervention Characterization Tool) was created in response to the frequently reported issue of poor intervention description across studies assessing the impact of clinical pharmacy activities. The aim of this study was to create an improved version of DEPICT (i.e. DEPICT 2) to better characterize clinical pharmacy services in order to ensure consistent reporting, therefore enhancing reproducibility of interventions in practice.

METHOD

A qualitative approach through a thematic content analysis was performed to identify components of pharmacist interventions described in 269 randomized controlled trials. A preliminary version of DEPICT 2 was applied independently by two authors to a random sample of 85 of the 269 RCTs and reliability determined by the prevalence-adjusted bias-adjusted kappa (PABAK) or the intraclass correlation coefficient (ICC). The final version of DEPICT 2 was compared against DEPICT 1.

RESULTS

The final version of DEPICT 2 comprised 146 items and 11 domains. The inter-rater agreement analysis showed that DEPICT presented good to optimal reproducibility, with a mean PABAK value of 0.87 (95% CI 0.85-0.89) and a mean ICC value of 0.88 (95% CI 0.62-1.14). The mean difference between items checked in the two versions (DEPICT 2 - DEPICT 1) was 10.58 (95% CI 9.55-11.61), meaning that approximately 11 more components were identified in the new version of DEPICT.

CONCLUSIONS

DEPICT 2 is a reliable tool to characterize components of clinical pharmacy services, which should be used to ensure consistent reporting of interventions to allow their reproducibility in practice.
