Assessment of drug-related problems and their impact on blood pressure control in patients with hypertension

Drug-Related Problems and Pharmacists' Interventions in Hypertensive Outpatients: A Multicenter Prospective Study in 3 Vietnamese Hospitals

Background: Clinical pharmacists' interventions (PIs) on drug-related problems (DRPs) in Vietnamese hypertensive outpatients are limited. Objectives: The objective was to investigate the prevalence and nature of DRPs, and factors which are likely to have DRPs, types of PIs, and their acceptance rate in 3 Vietnamese hospitals. Method: A prospective interventional study was conducted over a period of 3 months in 3 hospitals (from October 2021 to March 2022). Clinical pharmacists conducted medication reviews after collecting patient information from prescriptions and patient interviewing, and then identified the DRPs and suggested PIs according to the Vi-Med tool. These DRPs and PIs were reviewed by other superior clinical pharmacists and a consensus meeting with 3 cardiologists. Results: Of 381 patients included, 344 (90.23%) experienced 1 or more DRPs. A total of 820 DRPs were identified with an average of 2.15 DRPs per patient and 415 (50.61%) were hypertension-related issues. The most common DRPs identified were "administration mode" (46.34%), "missing indication" (18.05%), "non-conformity indication" (17.80%), and "dosage" (11.95%). Comorbidity (adjusted odds ratio [AOR] = 3.985, 95% CI: 1.597-9.942, P = 0.003) was the predictor of DRPs. Clinical pharmacists provided 739 PIs and 94.45% were accepted by physicians. Conclusion: The results of this study showed that DRPs were very common in hypertensive outpatients and highlighted the role of clinical pharmacists to identify and resolve DRPs through prompt interventions.

Effect of Pharmaceutical Intervention in Pharmacologically Treated Hypertensive Patients-A Cluster-Randomized Clinical Trial: AFPRES-CLM Study

BACKGROUND

Evaluate the effect of a community pharmaceutical intervention on the control of blood pressure in hypertensive patients treated pharmacologically.

METHODS

A cluster-randomized clinical trial of 6 months was carried out. It was conducted in the Autonomous Community of Castilla-La Mancha (Spain). Sixty-three community pharmacies and 347 patients completed the study. Intervention patients received the community pharmaceutical intervention based on a protocol that addresses the individual needs of each patient related to the control of their blood pressure, which included Health Education, Pharmacotherapy Follow-up and 24 h Ambulatory Blood Pressure Measurement. Control patients received usual care in the community pharmacy.

RESULTS

The pharmaceutical intervention resulted in better control of blood pressure (85.8% vs. 66.3% p < 0.001), lower use of emergencies (p = 0.002) and improvement trends in the physical components of quality of life, measured by SF-36 questionnaire, after 6 months of pharmaceutical intervention. No significant changes were observed for any of these variables in the control group. There were also detected 354 negative medication-related outcomes that were satisfactorily resolved in a 74.9% of the cases and 330 healthcare education interventions and 29 Ambulatory Blood Pressure Monitorings were performed in order to increase adherence to pharmacological treatment and minimize Negative Outcomes associated with Medication and prevent medication-related problems.

CONCLUSIONS

Community pharmaceutical intervention can increase hypertensive patients with controlled blood pressure, after 6 months, compared with usual care.

Evaluation of pharmaceutical care services in the Middle East Countries: a review of studies of 2013-2020

INTRODUCTION

Pharmaceutical care services (PCs) have evolved significantly over the last few decades, with a greater focus on patient's safety and proven effectiveness in a wide range of contexts. Many of the evidence supporting this technique comes from the United States, the evaluation and adoption of (PCs) which differ greatly across the globe.

OBJECTIVE

The goal of this study was to identify and assess the efficacy of pharmaceutical care services in various pharmaceutical aspects throughout seventeen Middle Eastern nations.

METHOD

The Arkesy and O'Malley technique was used to conduct a scoping review. It was conducted using PubMed/Medline, Scopus, Cochrane Library, Springer Link, Clinical Trials, and Web of Science etc. The Van Tulder Scale was utilized in randomized trials research, whereas the dawn and black checklists were used in non-randomized trials research. A descriptive and numerical analysis of selected research was done. The scope of eligible PCs, pharmaceutical implementers, study outcomes, and quality were all identified by a thematic review of research.

RESULTS

There were about 431,753 citations found in this study, and 129 publications were found to be eligible for inclusion after analysing more than 271 full-text papers. The study design was varied, with 43 (33.3%) RCTs and 86 (66.7%) n-RCTs. Thirty-three (25.6%) of the studies were published in 2020. Jordan, Saudi Arabia, and Turkey were home to the majority of the studies (25.6%, 16.3%, and 11.6%) respectively. Thirty-seven studies (19.7%) were concerned with resolving drug related problems (DRPs), whereas 27 (14.4%) were concerned with increasing quality of life (QOL) and 23 (12.2%) with improving drug adherence. Additionally, the research revealed that the average ratings of the activities provided to patients improved every year.

CONCLUSION

Studies in the Middle East continue to provide evidence supporting the positive impact of pharmaceutical care services on both hard and soft outcomes measured in most studies. Yet there was rare focus on the value of the implemented services. Thus, rigorous evaluation of the economic impact of implemented pharmaceutical care services in the Middle East and assessment of their sustainability is must.

The impact of telepharmacy on hypertension management in the United Arab Emirates

Objectives

To assess the effectiveness of telepharmacy services delivered by community pharmacies in hypertension management and examine its influence on pharmacists' ability to identify drug-related problems (DRPs).

Methods

This was a 2-arm, randomised, clinical trial conducted among 16 community pharmacies and 239 patients with uncontrolled HTN in the U.A.E over a period of 12 months. The first arm (n=119) received telepharmacy services and the second arm (n=120) received traditional pharmaceutical services. Both arms were followed up to 12 months. Pharmacists self-reported the study outcomes, which primarily were the changes in SBP and DBP from baseline to 12-month meeting. Blood pressure readings were taken at baseline, 3, 6, 9, and 12 months. Other outcomes were the mean knowledge, medication adherence and DRP incidence and types. The frequency and nature of pharmacist interventions in both groups were also reported.

Results

The mean SBP and DBP differences were statistically significant across the study groups at 3-, 6-, and 9-month follow-up and 3-, 6-, 9-, 12- month follow-up, respectively. In detail, the mean SBP was reduced from 145.9 mm Hg in the intervention group (IG) and 146.7 mm Hg in the control group (CG) to 124.5, 123.2, 123.5, and 124.9 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the IG and 135.9, 133.8, 133.7, and 132.4 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the CG. The mean DBP was reduced from 84.3 mm Hg in IG and 85.1 mm Hg in CG to 77.6, 76.2, 76.1, and 77.8 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the IG and 82.3, 81.5, 81.5, and 81.9 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the CG. Medication adherence and knowledge of participants in the IG towards hypertension were significantly improved. The DRP incidence and DRPs per patient identified by pharmacists in the intervention and control groups were 2.1% versus 1.0% (p=0.002) and 0.6 versus 0.3 (p=0.001), respectively. The total numbers of pharmacist interventions in the IG and CG were 331 and 196, respectively. The proportions of pharmacist interventions related to patient education, cessation of drug therapy, adjustment of drug dose, and addition of drug therapy across the IG and CG were 27.5% versus 20.9%, 15.4% versus 18.9%, 14.5% versus 14.8%, and 13.9% versus 9.7%, respectively (all with p<0.05).

Conclusion

Telepharmacy may have a sustained effect for up to 12 months on blood pressure of patients with hypertension. This intervention also improves pharmacists' ability to identify and prevent drug-related problems in community setting.

Pharmaceutical care and telemedicine during COVID-19: A cross-sectional study based on pharmacy students, pharmacists, and physicians in Jordan

Lack of access to the patient medical record (90.6%) was the major barrier for the integration of pharmaceutical care into practice. The majority of participants (93.0%) encouraged creating a website that provides pharmaceutical care. Furthermore, 45.1% would pay for such a service if present. Moreover, the majority (89.8%) agreed that creating a comprehensive database for patients’ data will help in decreasing medical errors. Among the four aspects of pharmaceutical care (technical, psychosocial, communication and administrative) that were assessed for students and pharmacist’s, general weakness in all aspects was noticed. This study highlights that absence of proper documentation of patient medical information raises the risk of medical problems and is considered the most documented barrier for the integration of pharmaceutical care. This emphasizes the future role of telemedicine and the availability of a specialized website and database repository that stores patient’s information to ensure the continuity of care even during pandemics.

Drug related problems in clinical practice: a cross-sectional study on their prevalence, risk factors and associated pharmaceutical interventions

Drug-related problems (DRP) cause preventable negative health outcomes, especially during hospital admissions. The aim of our study was to examine the prevalence and characteristics of DRP in regular clinical pharmacy, as well as to determine those factors associated with a higher risk of DRP in the hospital setting. We analyzed data from a standardized registry database of regular pharmacy practice (2015- 2016). DRP were classified according to the Pharmaceutical Care Network Europe v6.2 classification. Cross-sectional data were obtained from 1602 adults admitted to medical wards. Crude and adjusted binary logistic regressions were performed to identify associations between potential risk factors and DRP. Overall DRP prevalence was high across medical specialties (45,1%), in a population characterized by advanced age, polypharmacy and multimorbidity. Problems leading to DRP were mainly classified into two domains (effectiveness and adverse reactions), being drug and dose selection the most frequent causes. Interventions were accepted and DRP were totally or partially solved in 74.1% and 4.81% of cases, respectively. In the adjusted model polypharmacy, allergies, BMI > 25 kg/m2 and clearance < 30 mL/min were associated with a higher risk of DRP. The participation of clinical pharmacists into multidisciplinary teams promotes the detection and solution of DRP. Polypharmacy, obesity, renal impairment and allergy are associated with a higher risk of DRP during admission.

Patients' attitude and willingness to pay for pharmaceutical care: An international message from a developing country

BACKGROUND

Since patients are essential partners in determining priorities and resource allocation in the healthcare system, considerable efforts have been made to shift the focus of pharmacy profession from drug dispensing to patient-oriented care. Accordingly, the assessment of patient-oriented care has become a prominent method to evaluate the quality of the healthcare services delivered and willingness to pay (WTP) to receive them.

OBJECTIVE(S)

To determine patients' attitude towards pharmaceutical care services among general population in Jordan and their WTP for this service.

METHODS

A cross-sectional study was conducted in a teaching hospital in Jordan over a period of six months. A contingent valuation method was used, with closed-ended questions to elicit participants' attitudes and WTP for pharmaceutical care services.

RESULTS

A total of 223 participants were interviewed. Most of the participants showed a positive attitude towards pharmaceutical care services, with an average attitude score of 0.82 (±0.19). Almost 96.0% of participants believed that pharmacists must be committed to more counseling roles than dispensary activities. The majority of participants (194, 87.0%) expressed their interest in pharmacists checking their medications at least once per month. Most of the participants (212, (95.1%) believed that the pharmacist should be reimbursed for providing a pharmaceutical care service that would potentially reduce medication-related problems (MRPs) by 50%. Of these, 208 (93.3%) participants were willing to pay out of their pockets an average maximum amount of $3.95 (±4.23) for the pharmaceutical care services they may receive to reduce 50% of the risk of MRPs.

CONCLUSIONS

This study revealed that Jordanian people have a supportive attitude regarding pharmacists' abilities in providing pharmaceutical care services in addition to dispensing. Majority of participants in this study were willing to pay for pharmaceutical care services that would reduce the risk of MRPs.

Nurse-Led Intervention to Improve Knowledge of Medications in Survivors of Stroke or Transient Ischemic Attack: A Cluster Randomized Controlled Trial

INTRODUCTION

Limited evidence exists on effective interventions to improve knowledge of preventive medications in patients with chronic diseases, such as stroke. We investigated the effectiveness of a nurse-led intervention, where a component was to improve knowledge of prevention medications, in patients with stroke or transient ischemic attack (TIA).

METHODS

Prospective sub-study of the Shared Team Approach between Nurses and Doctors for Improved Risk Factor Management, a randomized controlled trial of risk factor management. We recruited patients aged ≥18 years and hospitalized for stroke/TIA. The intervention comprised an individualized management program, involving nurse-led education, and management plan with medical specialist oversight. The outcome, participants' knowledge of secondary prevention medications at 12 months, was assessed using questionnaires. A score of ≥5 was considered as good knowledge. Effectiveness of the intervention on knowledge of medications was determined using logistic regression.

RESULTS

Between May 2014 and January 2015, 142 consecutive participants from the main trial were included in this sub-study, 64 to usual care and 78 to the intervention (median age 68.9 years, 68% males, and 79% ischemic stroke). In multivariable analyses, we found no significant difference between intervention groups in knowledge of medications. Factors independently associated with good knowledge (score ≥5) at 12 months included higher socioeconomic position (OR 4.79, 95% CI 1.76, 13.07), greater functional ability (OR 1.69, 95% CI 1.17, 2.45), being married/living with a partner (OR 3.12, 95% CI 1.10, 8.87), and using instructions on pill bottle/package as an administration aid (OR 4.82, 95% CI 1.76, 13.22). Being aged ≥65 years was associated with poorer knowledge of medications (OR 0.24, 95% CI 0.08, 0.71), while knowledge was worse among those taking three medications (OR 0.15, 95% CI 0.03, 0.66) or ≥4 medications (OR 0.09, 95% CI 0.02, 0.44), when compared to participants taking fewer (≤2) prevention medications.

CONCLUSION

There was no evidence that the nurse-led intervention was effective for improving knowledge of secondary prevention medications in patients with stroke/TIA at 12 months. However, older patients and those taking more medications should be particularly targeted for more intensive education.
