Risk factors for clinically relevant deviations in patients’ medication lists reported by patients in personal health records: a prospective cohort study in a hospital setting

Background Personal health records have the potential to identify medication discrepancies. Although they facilitate patient empowerment and broad implementation of medication reconciliation, more medication discrepancies are identified through medication reconciliation performed by healthcare professionals. Aim We aimed to identify the factors associated with the occurrence of a clinically relevant deviation in a patient’s medication list based on a personal health record (used by patients) compared to medication reconciliation performed by a healthcare professional. Method Three- to 14 days prior to a planned admission to the Cardiology-, Internal Medicine- or Neurology Departments, at Amphia Hospital, Breda, the Netherlands, patients were invited to update their medication file in their personal health records. At admission, medication reconciliation was performed by a pharmacy technician. Deviations were determined as differences between these medication lists. Associations between patient-, setting-, and medication-related factors, and the occurrence of a clinically relevant deviation (National Coordinating Council for Medication Error Reporting and Prevention class $$\ge$$ ≥ E) were analysed. Results Of the 488 patients approached, 155 patients were included. Twenty-four clinically relevant deviations were observed. Younger patients (adjusted odds ratio (aOR) 0.94; 95%CI:0.91–0.98), patients who used individual multi-dose packaging (aOR 14.87; 95%CI:2.02–110), and patients who used $$\ge$$ ≥ 8 different medications, were at highest risk for the occurrence of a clinically relevant deviation (sensitivity 0.71; specificity 0.62; area under the curve 0.64 95%CI:0.52–0.76). Conclusion Medication reconciliation is the preferred method to identify medication discrepancies for patients with individual multi-dose packaging, and patients who used eight or more different medications.

Medication discrepancies among hospitalized patients with hypertension: assessment of prevalence and risk factors

Background Medication errors remained among the top 10 leading causes of death worldwide. Furthermore, a high percentage of medication errors are classified as medication discrepancies. This study aimed to identify and quantify the different types of unintentional medication discrepancies among hospitalized hypertensive patients; it also explored the predictors of unintentional medication discrepancies among this cohort of patients. Methods This was a prospective observational study undertaken in a large teaching hospital. A convenience sample of adult patients, taking ≥4 regular medications, with a prior history of treated hypertension admitted to a medical or surgical ward were recruited. The best possible medication histories were obtained by hospital pharmacists using at least two information sources. These histories were compared to the admission medication orders to identify any possible unintentional discrepancies. These discrepancies were classified based on their severity. Finally, the different predictors affecting unintentional discrepancies occurrence were recognized. Results A high rate of unintentional medication discrepancies has been found, with approximately 46.7% of the patients had at least one unintentional discrepancy. Regression analysis showed that for every one year of increased age, the number of unintentional discrepancies per patient increased by 0.172 (P = 0.007), and for every additional medication taken prior to hospital admission, the number of discrepancies increased by 0.258 (P= 0.003). While for every additional medication at hospital admission, the number of discrepancies decreased by 0.288 (P < 0.001). Cardiovascular medications, such as diuretics and beta-blockers, were associated with the highest rates of unintentional discrepancies in our study. Medication omission was the most common type of the identified discrepancies, with approximately 46.1% of the identified discrepancies were related to omission. Regarding the clinical significance of the identified discrepancies, around two-third of them were of moderate to high significance (n= 124, 64.2%), which had the potential to cause moderate or severe worsening of the patient´s medical condition. Conclusions Unintentional medication discrepancies are highly prevalent among hypertensive patients. Medication omission was the most commonly encountered discrepancy type. Health institutions should implement appropriate and effective tools and strategies to reduce these medication discrepancies and enhance patient safety at different care transitions. Further studies are needed to assess whether such discrepancies might affect blood pressure control in hypertensive patients.

Importance of medication reconciliation in cancer patients

Cancer patients are a complex and vulnerable population whose medication history is often extensive. Medication reconciliations in this population are especially essential, since medication discrepancies can lead to dire outcomes. This commentary aims to describe the significance of conducting medication reconciliations in this often-forgotten patient population. We discuss additional clinical interventions that can arise during this process as well. Medication reconciliations provide the opportunity to identify and prevent drug–drug and herb–drug interactions. They also provide an opportunity to appropriately adjust chemotherapy dosing according to renal and hepatic function. Finally, reconciling medications can also provide an opportunity to identify and deprescribe inappropriate medications. While clinical impact appears evident in this landscape, evidence of economic impact is lacking. As more cancer patients are prescribed a combination of oral chemotherapies, intravenous chemotherapies and non-anticancer medications, future studies should evaluate the advantages of conducting medication reconciliations in these patient populations across multiple care settings.

Medication Errors Detected in Primary Health Care after Hospital Discharge

Background: Medication conciliation allows finding discrepancies and medication errors in healthcare transitions, but there are few studies performed after hospital discharge, in the context of primary health care. Therefore, the main aim of this research was to evaluate the process of medication conciliation in primary health care, after hospital discharge. We further sought to analyze some demographic aspects of the patients that could be associated with potential discrepancies. Methods: A cross-sectional study was performed using the database which contained the records generated by the medication reconciliations performed by the physicians of the Andalusian Public Health Service, in Spain. Results: A total of 6115 medication conciliations were analyzed, and discrepancies were found in 73.7% of them. A total of 50.6% were medication errors, the most frequent being medication omission. Medication errors were more prevalent in women of 65 years and older. Conclusions: After hospital discharge, most patients show medication discrepancies in their records, particularly older women. To prevent this, primary health care plays an essential role in the conciliation process, therefore more research is needed in this context.

Differences in medication reconciliation interventions between six hospitals: a mixed method study

Background Although medication reconciliation (MedRec) is mandated and effective in decreasing preventable medication errors during transition of care, hospitals implement MedRec differently. Objective Quantitatively compare the number and type of MedRec interventions between hospitals upon admission and discharge, followed by a qualitative analysis on potential reasons for these differences. Methods This explanatory retrospective mixed method study consisted of a quantitative and a qualitative part. Patients from six hospitals and various wards were included if MedRec was performed both on hospital admission and discharge. Information on pharmacy interventions to resolve unintended discrepancies and medication optimizations were collected. Based on these quantitative results, interviews and a focus group was performed to give insight in MedRec processes. Descriptive analysis was used for the quantitative-, content analysis for the qualitative part. Results On admission, patients with at least one discrepancy varied from 36-95% (mean per patient 2.2 (SD +/- 2.4) Upon discharge, these numbers ranged from 5-28% while optimizations reached 2% (admission) to 95% (discharge).The main themes explaining differences in numbers of interventions were patient-mix, healthcare professionals involved, location and moment of the interview plus embedding and extent of medication optimization. Conclusions Hospitals differed greatly in the number of interventions performed during MedRec. A combination of patient-mix, healthcare professionals involved, location and timing of the interview plus embedding and extent of medication optimization resulted in the highest yield of MedRec interventions on unintended medication discrepancies and optimizations. This study supports to give direction to optimize MedRec processes in hospitals.

Clinical Pharmacist’s Contribution to Medication Reconciliation in Outpatient Specialty Clinics in Iran

Background: The majority of research in medication reconciliation has focused on the inpatient settings, and little is known about the outpatient settings, particularly in developing countries. As such, we conducted this study to evaluate direct clinical pharmacist involvement in medication reconciliation in outpatient specialty clinics in Iran. Methods: This prospective interventional study was conducted from September 2019 to February 2020 in a University-affiliated clinic in Iran. For 196 patients over 18 years of age who were scheduled for an appointment with a physician, medication reconciliation intervention was carried out by a clinical pharmacist. The number and type of unintentional discrepancies, their potential harm to the patients, their correlation with the patients' demographic and clinical characteristics, and the number of accepted recommendations upon the unintentional discrepancies by the clinicians were assessed and recorded. Additionally, patients' understanding of any change made to their current medication regimen was also assessed. The association between the unintentional discrepancies with patients' characteristics was also assessed. Results: Totally, 57.14% of patients had at least one or more unintentional medication discrepancies, with an overall rate of 1.51 (±0.62) per patient. This is while the patient understanding of their medication changes was inadequate in a significant proportion of the study patients (62.2%). Patients with older ages, lower educational levels, and a higher number of medications and comorvidities were at a higher risk of having unintentional discrepancies. The most common type of unintentional discrepancy was the omission of a drug, and almost half of the reconciliation errors might have had the potential to cause moderate or severe harm to the patient. From 145 recommendations suggested by the clinical pharmacist upon unintentional discrepancies, 131 cases (90.34%) were accepted and implemented by the clinicians. Conclusion: These findings further support the need for conducting medication reconciliation in outpatient settings to identify discrepancies and enhance the safety of patient medication use.

Medication Discrepancies and Regimen Complexity in Decompensated Cirrhosis: Implications for Medication Safety

Discrepancies between the medicines consumed by patients and those documented in the medical record can affect medication safety. We aimed to characterize medication discrepancies and medication regimen complexity over time in a cohort of outpatients with decompensated cirrhosis, and evaluate the impact of pharmacist-led intervention on discrepancies and patient outcomes. In a randomized-controlled trial (n = 57 intervention and n = 57 usual care participants), medication reconciliation and patient-oriented education delivered over a six-month period was associated with a 45% reduction in the incidence rate of ‘high’ risk discrepancies (IRR = 0.55, 95%CI = 0.31–0.96) compared to usual care. For each additional ‘high’ risk discrepancy at baseline, the odds of having ≥ 1 unplanned medication-related admission during a 12-month follow-up period increased by 25% (adj-OR = 1.25, 95%CI = 0.97–1.63) independently of the Child–Pugh score and a history of variceal bleeding. Among participants with complete follow-up, intervention patients were 3-fold less likely to have an unplanned medication-related admission (adj-OR = 0.27, 95%CI = 0.07–0.97) compared to usual care. There was no association between medication discrepancies and mortality. Medication regimen complexity, frequent changes to the regimen and hepatic encephalopathy were associated with discrepancies. Medication reconciliation may improve medication safety by facilitating communication between patients and clinicians about ‘current’ therapies and identifying potentially inappropriate medicines that may lead to harm.

Pharmacy student-assisted medication reconciliation: Number and types of medication discrepancies identified by pharmacy students

Background: Medication reconciliation aims to prevent unintentional medication discrepancies that can result in patient harm at transitions of care. Pharmacist-led medication reconciliation has clear benefits, however workforce limitations can be a barrier to providing this service. Pharmacy students are a potential workforce solution. Objective: To evaluate the number and type of medication discrepancies identified by pharmacy students. Methods: Fourth year pharmacy students completed best possible medication histories and identified discrepancies with prescribed medications for patients admitted to hospital. A retrospective audit was conducted to determine the number and type of medication discrepancies identified by pharmacy students, types of patients and medicines involved in discrepancies. Results: There were 294 patients included in the study. Overall, 72% (n=212/294) had medication discrepancies, the most common type being drug omission. A total of 645 discrepancies were identified, which was a median of three per patient. Patients with discrepancies were older than patients without discrepancies with a median (IQR) age of 74 (65-84) vs 68 (53-77) years (p=0.001). They also took more medicines with a median (IQR) number of 9 (6-3) vs 7 (2-10) medicines per patient (p<0.001). The most common types of medicines involved were those related to the alimentary tract and cardiovascular system. Conclusions: Pharmacy students identified medication discrepancies in over 70% of hospital inpatients, categorised primarily as drug omission. Pharmacy students can provide a beneficial service to the hospital and contribute to improved patient safety by assisting pharmacists with medication reconciliation.

Oral anti-tuberculosis drugs: An urgent medication reconciliation at hospitals in Indonesia

Background: Four oral anti-tuberculosis drugs are conceived to be the most effective ones to eradicate Mycobacterium tuberculosis bacteria and to obviate the resistant organisms. However, the patients' adherence and medication discrepancies are obstacles to achieving the goal. This study aimed to define the anti-tuberculosis drugs used in the hospitals and to detect the discrepancies in the continuity of the tuberculosis treatment.Design and Methods: This retrospective cross-sectional study was based on medical records of adult patients, and was conducted in two district tertiary care hospitals. Only 35 out of 136 patient records from Hospital A and 33 out of 85 records from Hospital B met the inclusion criteria.Results: The most common systemic anti-infective drugs in the study were ceftriaxone (51.80 DDD/100 patient-days) used in Hospital A and isoniazid (59.53 DDD/100 patient-days) used in Hospital B. The number of rifampicin prescriptions was less than that of isoniazid. Each patient received an average of two DDD/100 patient-days, which is an under dosage for an effective treatment.Conclusion: This study showed a medication discrepancy of Tuberculosis therapy. Tuberculosis patients’ medical histories are not under the full attention of treating physicians wherever they are admitted. Thus, medication reconciliation is needed to accomplish the goal of a Tuberculosis-free world in 2050.
