The Association between Drug-Related Problems and Length of Stay of Type 2 Diabetes Mellitus Patients

Introduction

Drug-related problems (DRPs) are treatment-related occurrences that affect therapeutic efficacy. In a previous study, approximately 279 out of 330 (84.5%) patients with type 2 diabetes mellitus (T2DM) had experienced at least one DRP, including non-optimal drug effects (n = 240, 52.7%) and indications without medication (n = 137, 30.1%). Patients who were hospitalised for 5-10 days had the highest number of DRPs. Therefore, this study investigates the association between DRPs and length of stay (LoS) in patients with T2DM.

Methods

A cross-sectional study was conducted from January 2020 to May 2023 at Rumah Sakit Akademik, Universitas Gadjah Mada, Yogyakarta, Indonesia. Clinical pharmacists reviewed electronic health data to examine DRPs. The Fisher's exact test evaluated the association between DRPs and LoS.

Results

A total of 60.7% (n = 17) of the participants were females, with the majority falling into the age group ≥ 65 years old (n = 11, 29.7%). A significant portion experienced LoS > 7 days (n = 17, 60.7%). Antidiabetic monotherapy was predominant, and the categories of DRPs included adverse drug reaction (n = 15, 40.5%), dosage too high (n = 6, 16.2%), wrong drug (n = 6, 16.2%), non-adherence (n = 4, 10.8%), need for additional therapy (n = 4, 10.8%) and dosage too low (n = 2, 5.4%). A significant association was observed between non-adherence and LoS (P = 0.016). The possibility of experiencing LoS of 1-7 days increased by 3.43 times with improved non-adherence (OR = 3.43; 95% CI: 1.83, 6.39). In this context, non-adherence refers to DRPs associated with the non-compliance of patients with the prescribed treatment plan.

Conclusion

This study concludes that non-adherence was significantly associated with hospital LoS.

Patterns of drug-related problems and the services provided to optimize drug therapy in the community pharmacy setting

Introduction

Drug-related problems (DRPs) are events or circumstances involving drug therapy that actually or potentially interferes with desired health outcomes.

Objectives

To assess community pharmacists' knowledge and practice regarding DRP-reduction services, as well as the barriers and factors associated with decreased provision of these services.

Methods

This cross-sectional study utilized a validated questionnaire to assess pharmacists' knowledge, practice, and barriers to the provision of DRP-reduction services in the community pharmacy setting. Binary regression model was used to assess the variables associated with the practice of DRP-reduction services.

Results

A total of 412 pharmacists participated in the study. The pharmacists demonstrated strong knowledge but inadequate practice of DRP-reduction services. The most reported DRPs were inappropriate combination of drugs, or drugs and herbal medications, or drugs and dietary supplements (52.4%), patients' inability to understand instructions properly (46.1%), inappropriate drug according to guidelines (43.7%), and too high dose (40.3%). The most common barriers to these services were increased workload (60.5%), limited time (53.2%), and lack of good communication skills (49.8%). The presence of a counselling area in the pharmacy increased the practice of DRP-reduction services (OR: 3.532, 95%Cl: 2.010-5.590, P < 0.001), while increased weekly working hours (OR: 0.966, 95%Cl: 0.947-0.986), P < 0.01) and serving < 10 patients daily (OR = 0.208, 95%Cl: 0.072-0.601, P < 0.01) decreased it.

Conclusions

Community pharmacists' practice of DRP-reduction services showed a scope for improvement. Future pharmaceutical care initiatives should increase the number of personnel working in the pharmacy and provide them with opportunities for continued education and training in order to improve the provision of DRP services and optimize patients' outcomes.

Patient Safety Culture in Handling Prescriptions and Interprofessional Collaboration Practices Amongst Community Pharmacists: An Investigative Simulated Patient Study from the United Arab Emirates

Background

Community pharmacists are in a unique position to identify drug therapy-related problems (DTRPs) in prescriptions and mitigate them by communicating with prescriber. This study assessed the ability of community pharmacists (CPs) to identify DTRPs in prescriptions, the level of interprofessional collaboration among physician and CPs in mitigating the identified DTRPs, and the existing safety culture practices among CPs.

Methods

Trained simulated patients (SPs), five final-year BSc Pharm female students, visited conveniently selected community pharmacies (n = 50) in Ajman emirate of the United Arab Emirates, with dummy prescriptions containing DTRPs (total 50 prescriptions with five different types of DTRPs categorized per the Pharmaceutical Care Network Europe Version 8) and assessed the DTRP-identifying ability of the CPs. SPs also observed the steps taken by the CPs to mitigate identified DTRPs and existing (if any) collaborative practices between CPs and physician. SPs documented their observations in a checklist immediately after leaving the pharmacy premises, which served as the data source. Statistical analyses were performed with chi-square at alpha = 0.05.

Results

Of the 50 respondents, 44% (n = 22) were able to identify the DTRPs. DTRP identification by pharmacists was associated with labeling [chi-square = 7.879, p value = 0.019], reconciliation [chi-square = 10.359, p value = 0.001], counseling standard [chi-square = 19.09, p = 0.000] and physician visit suggestion [chi-square = 31.15, p = 0.000]. The labeling standards for prescriptions with DTRPs were “low” in five (50%), “average“ in three (30%) and “good” in two (20%) of the cases with wrong dose. Average counseling time of the CPs was 80.38 ± 71.61 seconds. The counseling standard had no significant association with counseling time [chi-square = 34.79, p = 0.250] and use of drug information sources [chi-square = 2.86, p = 0.243]. Average time spent in dispensing is 74.4 ± 73.05 seconds. None (n = 0) of the CPs communicated with the physician, and only five out of 50 (10%) of CPs checked any DI sources. However, in 19 (38%) cases, the CPs recommended the SPs to consult their physician prior to taking the medications.

Conclusion

CPs were generally able to identify DTRPs and mitigate DTRPs by recommending physician consultation. Nevertheless, there were no professional collaborations between the SPs and physicians. The dispensing and counseling standards were not appreciable.

Effectiveness of medication review on the number of drug-related problems in patients visiting the outpatient cardiology clinic: A randomized controlled trial

AIMS

To assess the effectiveness of medication review on the number of drug-related problems (DRPs) in outpatient cardiology patients.

METHODS

In this randomized controlled trial, a computer-assisted and pharmacist-led medication review with patient involvement (questionnaire and telephone call with pharmacist) was conducted in intervention patients prior to their visit to the cardiologist. The control group received usual care. Adult outpatient cardiology patients without support concerning the administration of medication, without a medication review in the past 6 months and who gave permission to access their electronic medication record were included. The primary outcome measure was the number of DRPs 1 month after the visit. Secondary outcome measures concerned the type of DRP and the type of medication involved in the DRPs.

RESULTS

In total, 75 patients (mean [standard deviation, SD] age 66.0 [12.5] years, 41% female) were included. Intervention (n = 90) and control group (n = 85) were comparable at baseline. The mean (SD) number of drugs used per patient was 7.9 (3.9). After 1 month, the mean (SD) number of DRPs was 0.3 (0.7) and 0.8 (1.0) and the median (range) number of DRPs was 0 (0-4) and 0 (0-4) in the intervention group and control group, respectively (P < .001). In the intervention group, 74% of the DRPs identified at T0 were solved at T1 vs 14% in the control group.

CONCLUSION

This randomized controlled trial suggests that a pharmacist-led medication review in patients with a scheduled visit to the outpatient cardiology clinic decreases the number of DRPs.
