Cost-effectiveness of comprehensive medication reviews versus noncomprehensive medication review interventions and subsequent successful medication changes in a Medicare Part D population

Medication reviews by emergency department pharmacists in patients hospitalised for an adverse drug event: a cost study

OBJECTIVE

To perform a cost study of pharmacist-led medication reviews in patients with an acute hospitalization for adverse drug events.

METHOD

Emergency department pharmacists performed medication reviews in patients hospitalized after visiting the emergency department for an adverse drug event (ADE). Control patients were hospitalized after an emergency department visit not related to an ADE and received usual care. The costs of the intervention were labour costs of the junior emergency department pharmacist and the cost savings consisted of costs of medication that was stopped or reduced during six months after the intervention. Sensitivity analyses were performed to evaluate different scenarios.

RESULTS

In the intervention group (n = 104) 113 medication changes led to stopping or reducing medication, accounting for averted costs of €22,850. In the control group (n = 112) 39 medication changes led to stopping or reducing medication, accounting for averted costs of €299. The mean labour costs of the intervention were €138 per patient, resulting in saved costs of €61 per patient per six months. Sensitivity analyses showed that if the intervention would be performed by a senior clinical pharmacist, there are no cost savings (€-21), if parts of the intervention would be executed by pharmacy technicians (e.g. administrative tasks), cost savings would be augmented to €87, if outliers in costs associated with medication reduction would be excluded, there are no cost savings (€-35) and if the costs of reduced medication were extrapolated to one year, cost savings would be €260.

CONCLUSION

In this study, medication reviews by junior emergency department pharmacists in patients hospitalized after an emergency department visit for an ADE lead to a cost reduction over a six month period.

Implementation of pharmaceutical care for older adults in the brazilian public health system: a case study and realistic evaluation

BACKGROUND

Pharmaceutical care services have been recognized as the most highly regarded professional pharmacy practice model that allows the identification, intervention, and resolution of drug related problems. This practice provides significant clinical outcomes and can reduce direct and indirect costs for health systems. However, its implementation can be complex and challenging, needing study experiences that aims at overcoming obstacles, especially in free and universal healthcare systems. The objective of this study is to evaluate the implementation of Ambulatory Care Pharmacy services for older adults at Paulista Institute of Geriatrics and Gerontology (IPGG), which is recognized in the city of São Paulo for offering pharmaceutical care services for over 10 years continuously. This initiative and process is independent of external academic interventions or educational institutions. It is hoped that the results may also contribute to advancing the implementation of pharmaceutical care service in similar health systems.

DESIGN

This is a case study using multiple sources of data. Qualitative and quantitative data were collected from institutional documents, by participant observation and interviews. Initial themes were identified by content analysis and analyzed under the context-mechanism-outcome configurations (CMO Configurations) in realistic evaluation.

SETTING

Geriatrics and Gerontology Institute of São Paulo (known as IPGG).

PARTICIPANTS

Eleven health professionals and three pharmaceutical care service users.

RESULTS

Three CMO configurations were identified and accepted: "Scenario Construction mediated by educational processes", "Contribution to complex needs resolution", and "Organizational Visibility". The CMO (Context-Mechanism-Outcomes) configuration "Logistic activities discourage clinical pharmaceutical services implantation" was denied due to the influence of accepted CMOs.

CONCLUSIONS

Educational processes which value transdisciplinary knowledge exchanges provide resources required to overcome important obstacles present during pharmaceutical care implementation. Thus, providing and seeking knowledge to build and offer context-consistent clinical health services as well as fulfilling organizational environment requirements can be the key to implement pharmaceutical care service.

Comparison of Medication Therapy Management Services and Their Effects on Health Care Utilization and Medication Adherence

BACKGROUND

Medication therapy management (MTM) programs are designed to improve clinical outcomes and enhance appropriate medication use. Comprehensive medication reviews (CMRs) and targeted medication reviews (TMRs) are 2 broad interventions defined within MTM services. While MTM services have been extensively researched, there are few comparisons of CMR versus non-CMR interventions. Given the variability in MTM interventions and lack of a consistent TMR definition in the literature, this study sought to compare CMRs and TMRs that were clearly defined based on Centers for Medicare & Medicaid Services (CMS) criteria.

OBJECTIVES

To (a) compare acute inpatient admissions and emergency department (ED) visits between patients participating in MTM services (CMR, TMR, or both) and eligible nonparticipating patients and (b) examine the effect of receiving TMR services on medication adherence.

METHODS

This was a retrospective cohort study of patients with Medicare Part D coverage who received MTM services and a 1:1 propensity score-matched control group. Participants had to be eligible for MTM services in 2014 or 2015 based on CMS requirements. CMRs were offered to all MTM-eligible patients, while TMRs were completed based on clinical rules that helped identify medication-related problems (MRPs). The date of MTM intervention, or eligibility for the control group, was considered the index date. Participants had to be continuously enrolled in a Medicare Advantage plan that included prescription drug coverage during the study period and have at least 6 months of data before and after the index date. Medical and pharmacy claims were assessed to examine trend-adjusted inpatient admissions and ED visits from pre-index to post-index date for participants and matched controls.

RESULTS

In 2014 and 2015, receipt of TMR interventions was associated with statistically significant reductions in acute inpatient admissions. In 2014, there were 55.2 fewer admits per 1,000 individuals (95% CI = 29-81) and 30.8 fewer admits per 1,000 individuals in 2015 (95% CI = 20-42). Receipt of CMR-only interventions was associated with fewer acute inpatient admissions only when coupled with preidentification of MRPs (36.8 [95% CI = 25-49] fewer admits per 1,000 individuals). In 2015, there were significant reductions in ED visits for participants receiving TMR-only interventions or TMR/CMR interventions (26.1 [95% CI = 11-41] and 12.0 [95% CI = 1-23] fewer ED visits per 1,000 individuals, respectively). In both years, a larger percentage (0.4% for oral diabetes medications; 7.7% for antihypertensives; 3.0% for statins) of MTM participants had greater improvements in medication adherence in the post-index period compared with controls.

CONCLUSIONS

Receiving MTM services targeted at resolution of MRPs (TMR or CMR/TMR) resulted in positive reductions in health care utilization and increases in medication adherence. Given the importance of optimal medication utilization, this study highlights the need for additional focus on resolution of MRPs through TMRs and CMRs that can support improved clinical outcomes.

Priority Setting and Influential Factors on Acceptance of Pharmaceutical Recommendations in Collaborative Medication Reviews in an Ambulatory Care Setting - Analysis of a Cluster Randomized Controlled Trial (WestGem-Study)

BACKGROUND

Medication reviews are recognized services to increase quality of therapy and reduce medication risks. The selection of eligible patients with potential to receive a major benefit is based on assumptions rather than on factual data. Acceptance of interprofessional collaboration is crucial to increase the quality of medication therapy.

OBJECTIVE

The research question was to identify and prioritize eligible patients for a medication review and to provide evidence-based criteria for patient selection. Acceptance of the prescribing general practitioner to implement pharmaceutical recommendations was measured and factors influencing physicians' acceptance were explored to obtain an impression on the extent of collaboration in medication review in an ambulatory care setting.

METHODS

Based on data of a cluster-randomized controlled study (WestGem-study), the correlation between patient parameters and the individual performance in a medication review was calculated in a multiple logistic regression model. Physician's acceptance of the suggested intervention was assessed using feedback forms. Influential factors were analyzed.

RESULTS

The number of drugs in use (p = 0.001), discrepancies between prescribed and used medicines (p = 0.014), the baseline Medication Appropriateness Index score (p<0.001) and the duration of the intervention (p = 0.006) could be identified as influential factors for a major benefit from a medication review, whereas morbidity (p>0.05) and a low kidney function (p>0.05) do not predetermine the outcome. Longitudinal patient care with repeated reviews showed higher interprofessional acceptance and superior patient benefit. A total of 54.9% of the recommendations in a medication review on drug therapy were accepted for implementation.

CONCLUSIONS

The number of drugs in use and medication reconciliation could be a first rational step in patient selection for a medication review. Most elderly, multimorbid patients with polymedication experience a similar chance of receiving a benefit from a medication review. Longitudinal patient care should be preferred over confined medication reviews. The acceptance of medication reviews by physicians supports further implementation into health care systems.

Pharmacotherapy review: a proposal to improve medication adherence among hypertensive patients

Abstract Pharmacotherapy review is a structured assessment of medicines, which aims to obtain a partnership with patients to achieve drug treatment goals and agreement about drug dosage, as well as when and how the drugs should be administered. The objective was to analyze the influence of pharmacotherapy review, by scheduling drug administration to improve medication adherence among antihypertensive patients. This study was an uncontrolled intervention developed in three distinct stages. The first stage included data collection on the profile of patients and their medications, and a preliminary assessment of medication adherence. In the second stage, the review report was delivered to patients. In the third stage, the results of blood pressure and medication adherence were assessed. The influence of the revision was measured through statistical tests (p<0.05). The study included 40 patients with a mean age of 58.0 (SD:11.3) years; 72.5% were women. Thirty-three (82.5 %) patients required some intervention, after when there was a significant increase in the number of daily doses (p=0.039) and drug intakes (p=0.025). There was a significant increase in the adherence rate, according to both the Morisky-Green test (p<0.001) and self-reported assessment (p=0.004). There was also an improvement in the levels of systolic (p<0.001) and diastolic (p=0.002) blood pressure and in the number of patients with controlled hypertension (p=0.006). The pharmaceutical service enhanced medication adherence and control of systemic blood pressure; however, it increased the complexity of treatment.
