Insights
Adverse drug events (ADEs) are frequent in hospitalized patients with chronic kidney disease (CKD). A significant portion of these drug events were preventable, highlighting the need for pharmacist interventions to improve patient safety.
Area of Science:
- Nephrology
- Clinical Pharmacy
- Pharmacovigilance
Background:
- Adverse drug events (ADEs) are a significant cause of hospitalizations and complications.
- Patients with chronic kidney disease (CKD) are particularly vulnerable to ADEs due to altered drug metabolism and excretion.
Purpose of the Study:
- To determine the incidence, characteristics, severity, and preventability of pre-admission and in-hospital ADEs in CKD patients.
- To identify medication classes most frequently associated with ADEs in this population.
Main Methods:
- Retrospective review of medical records and charts of 300 adult CKD patients at a nephrology unit.
- Daily assessment by a clinical pharmacist for evidence of drug-related errors or complications.
- Detailed investigation of suspected ADEs to ascertain causality, severity, and preventability.
Main Results:
- 159 ADEs were reported in 122 (40.7%) patients.
- 48 (30.2%) of ADEs were deemed preventable.
- Diuretics, antibacterials, antidiabetics, antithrombotics, mineral supplements, and antihypertensives were the most implicated drug classes.
Conclusions:
- ADEs are highly prevalent in hospitalized CKD patients.
- A substantial number of ADEs in this cohort are preventable.
- Clinical pharmacist involvement shows potential for reducing ADEs and enhancing patient safety.
Background And Objective:
Adverse drug events (ADEs) are a common cause of hospitalization and in-hospital complications. The aim of this study was to determine the rates, types, severity and preventability of pre-admission and in-hospital ADEs in patients with chronic kidney disease (CKD).
Methods:
This study was conducted at the nephrology unit at Penang General Hospital. A random sample of 300 adult patients with CKD was included. Medical records and charts were reviewed by a clinical pharmacist every work day to find any evidence of errors or complications related to drug use. If a suspected ADE was found, further investigations were carried out to assess the causality, severity and preventability of the event.
Results:
A total of 159 ADEs were reported in 122 (40.7%) of the patients. We found 86 suspected pre-admission ADEs in 68 (22.7%) of the patients. These were either the cause of admission for some patients or discovered by the initial physical examination and laboratory investigations. During hospitalization, 64 (21.3%) patients had 73 suspected ADEs. Out of the total 159 suspected ADEs, it was highly probable that 31 events were due to medication, while 61 were of lower probability, and 67 were merely possible. A total of 48 (30.2%) events was considered preventable. 46 events (28.9%) were serious, 93 (58.5%) were less serious and 20 (12.6%) were insignificant. The medication classes most frequently involved in ADEs were diuretics, antibacterials, drugs used for diabetes mellitus, antithrombotic agents, mineral supplements and antihypertensive drugs.
Conclusion:
ADEs are very common in hospitalized CKD patients, and some of these events are preventable. The service of a clinical pharmacist may help to reduce ADEs.
