Why was it done?

Complex medication regimens (MR) are associated with worse treatment adherence. The Medication Regimen Complexity Index (MRCI) is a validated tool used to quantify complexity of MR and it is the sum of the score in three sections: Dosage forms (A), dosing frequency (B) and additional directions (C).

What was done?

To assess the relative MR complexity among solid organ transplant patients (SOT; kidney, heart, lung and liver) in a tertiary hospital through the validated MRCI Spanish version.

How was it done?

Transplant patients who collected medication in the Hospital Pharmacy between January and March 2021 were selected. A total amount of 40 patients (ten per transplant) were chosen randomly through Excel®, and a macro with a template of MCRI was created. The qualitative variables were age, sex and type of transplant; the quantitative ones were months from transplant, total amount of medications, sections A, B, C and total MRCI. All prescribed medications documented in medical records at the hospital ambulatory clinics and the electronic medication list were included. Patients were excluded if they were followed-up in other hospitals, were exitus or MR dosage or frequency was missed/unclear. Subgroup analyses was made to assess MRCI among type of transplants through ANOVA. All data analysis were made with SPSS® version 23, with a <0,05 significance level and a confidence interval of 95%.

What has been achieved?

Sample median age was 56,6±14,7 years (95%CI:51,9-61,3), a 40%(16/40) were women, median of time from trasplant was 92,7±69,9 months (95%CI:70,4-115,0) and number of medications 11,1±4,6 (95%CI:9,6-12,6). Subgroup median MCRI were 23,3±10,2 (kidney; [95%CI:16,0-30,5]), 46,2±12,8 (lung; [95%CI:37,1-55,3]), 28,5±11,1 (heart; [95%CI:20,6-36,4]) and 18,7±5,4 (liver; [95%CI:14,8-22,5]). Section B was the most contributor to MCRI (16,6±8,2 [95%CI:14,0-19,2]), followed by C (6,6±4,3 [95%CI:5,2-7,9]) and A (5,7±3,7 [95%CI:4,5-6,9]). Tukey test showed a statistically significant MCRI in lung transplant with p<0,001 when compared to kidney and liver transplants, and p=0,002 compared to heart transplant.

What next?

Medication regiment of our sample was more complex in lung patients than in any other SOT, therefore these patients could benefit more pharmaceutical interventions. Further studies with bigger samples are required to confirm differences among kidney, liver and heart transplants.

Deprescribing interventions performed by hospital pharmacists reduce potentially inappropriate medication at hospital discharge

Why was it done?

In CCPs the efficacy and safety of many drugs are unknown or questionable, in fact, medication may be the cause for side effects. Deprescribing is aimed to reduce the use of potentially inappropriate medications (PIMs) and improve patient outcomes. Pharmacist deprescribing interventions may contribute to reassess prescriptions and withdraw those with a negative risk/benefit balance.

What was done?

To analyze the pharmacist deprescribing interventions in complex chronic patients (CCPs) performed in hospital and primary care.

How was it done?

This prospective study was carried out in a tertiary hospital between February and March 2021. CCPs whom medication was reconciliated at hospital discharge were included and the pharmacist interventions (PIs) performed were analyzed. After hospital discharge, the acceptance of the PIs was verified and were notified to the primary care physician in case of not being accepted in hospital setting. Drugs involved in PIs were classified according to the therapeutic group established by the Anatomical Therapeutic Chemical classification and high-risk medication was quantified using the Institute for Safe Medication Practices classification for chronic patients. Deprescribing interventions were classified according to the Less-Chron criteria and other medication-related problems were also quantified.

What has been achieved?

Among the 55 patients included, 55% were female, the mean age was 83 years and the mean of medication per patient was 13. A total of 111 PIs were performed, 44% (n = 49) were deprescribing interventions and 56% (n = 63) other problems related to medication. Fifty-five per cent of patients presented 1 or more PIMs, and a mean of approximately 1 PIMs per patient was reported. The most frequent therapeutic groups involved in PIs were cardiovascular system (34.2%), nervous system (29.7%) and alimentary tract and metabolism medication (13.5%). High-risk medication represented 41% of all PIs. The most frequent deprescribing interventions were associated to blood pressure treatment (30.6%), benzodiazepines (24.4%) and statins (12%). The 65% of deprescribing interventions were accepted among hospital and primary care settings.

What next?

Deprescribing interventions supported by hospital pharmacists reduce potentially inappropriate medications, however, deprescribing practice is still limited in hospital and primary care.

PREPARATION OF A COMPATIBILITY CHART IN “Y” FOR AREAS OF CRITICALLY ILL PATIENTS

Why was it done?

In the areas of critically ill patients such as emergency, intensive care and resuscitation, the use of intravenous drugs (IV) in “Y” are common in clinical practice. Stability and physical-chemical compatibility of IV drugs admistered in “Y” are important, affecting directly the safety of patients and the therapeutic efficacy of medicines, which can lead to medication errors (ME). A quick reference chart was developed in order to facilitate the administration of these drugs and reduce errors in these areas.

What was done?

A chart for quick reference of compatibility of drugs in “Y” for the most commonly used drugs in the areas of critically ill patients of our hospital.

How was it done?

It was a team composed of a doctor specializing in emergency medicine, a nurse and two hospital pharmacists. Economic management of pharmacy program Farmatools® was used to obtain the list of drugs most consumed and those most relevant and specific of these areas were selected.
A chart was made where the header of the rows and the columns was the list of drugs in the study. Finally, we conducted a systematic research on Micromedex® “Y” compatibility with each drug with the remaining, completed the chart with a visual color code: green (compatible), red (incompatible), white (not tested) and orange (precaution, existence of various stability dilutions and consult your pharmacist).

What has been achieved?

The elaboration and implementation of this table will provide a fast and visual consultation instrument to nurses before the administration of drugs in “Y”. This tool intended to facilitate decision-making, contributing to increase the effectiveness of the drugs and avoid possible adverse reactions in patients, increasing the quality of care and lowering the ME.

What next?

We are still working on the same areas to increase safety in drug therapy in critical care. Currently, that improvement measures that are being developed are: new pharmacotherapeutic protocols specifically for those units: high risk medications perfusion protocols and new safety guidelines.

EAHP Forum

All the EAHP team is working on providing a Forum that can help connect all the members in Conversations and Groups to talk about important matters for the European Hospital Pharmacist.

The Forum will be accessible for all the EAHP members, you don’t have to create a new account to browse and participate.

Conversations and groups

The Conversations will be moderated by our team to provide documents and relevant topics for the community.

The Groups will connect all members that share a category. Members who work on the same assocation, on the same hospital, that have the same role, etc.
