Impact of pharmacist interventions on drug-related problems in general surgery patients: a randomised controlled trial

Cost-effectiveness of preoperative pharmaceutical care consultations: a 5-year analysis

OBJECTIVES

Preoperative medication errors can be prevented by screening patients through a preoperative pharmaceutical care consultation. The aim of this study was to analyse the cost-effectiveness of implementing such a consultation and to determine which patients would benefit most.

METHODS

A retrospective study was conducted that included all patients who underwent a preoperative pharmacy consultation between 2016 and 2020. During this consultation, two part-time pharmacists reviewed patients' appropriate preoperative chronic medication management. All prevented errors were collected and classified by therapeutic group and type of error. A team of pharmacists and anaesthetists assigned to each prevented medication error a probability of causing an adverse event 'p', following the methodology of Nesbit et al by establishing five different 'p' values: 0, 0.01, 0.1, 0.4, and 0.6. 'p' = 1 was not considered. The cost of an adverse event was determined to be between €4124 and €6946 according to current literature, and a sensitivity analysis was performed by increasing the interval by 20% above and below. The cost of employing two part-time specialist pharmacists was estimated to be €59 142. Savings per medication error prevented were calculated as (€4124 OR €6946) × 'p'. Total savings were the sum of all costs associated with prevented medication errors. Patients on chronic medications who were in therapeutic groups with a 0.6 probability of an adverse event or who were in therapeutic groups responsible for 50% of the prevented adverse events were considered prioritisable.

RESULTS

3105 patients attended the consultation and 1179 medication errors were prevented, corresponding to 300 adverse events. 42.2% of the errors had a 'p' of 0.4. The costs avoided by this consultation ranged from €1 237 200 to €2 083 800, while the cost of its implementation was €295 710. The cost-effectiveness ratio was between €4.2 and €7.0 saved per euro invested. In the sensitivity analysis, the ratios ranged from €3.3 to €8.5 per euro invested. Fifteen different therapeutic groups accounted for 90% of the medication errors prevented. The therapeutic groups 'Agents acting on the renin-angiotensin system', 'Antidiabetics, non-insulin (excluding SGLT2)' and 'Antithrombotics: low molecular weight heparins' were responsible for 56% of the prevented adverse events. The therapeutic groups 'Antidiabetics: rapid-acting insulin' and 'Antithrombotic agents: vitamin K antagonists, low-molecular-weight heparins, or direct oral anticoagulants' had a 'p' of 0.6. Therefore, patients in six therapeutic groups should be prioritised for preoperative pharmacy counselling.

CONCLUSIONS

The implementation of preoperative pharmaceutical care consultations in Spain has proven to be cost-effective. Incorporating the probability of a medication error causing an adverse event allowed the prioritisation of patients for these consultations. Patients taking anticoagulants, oral antidiabetics, rapid-acting insulins, and agents acting on the renin-angiotensin system benefited the most. This study could serve as a basis for implementing such consultations in other hospitals, as they are effective in reducing the cost of medication errors in surgical patients.

Impact of preoperative pharmaceutical care consultation on medication errors in surgical patients: a comprehensive analysis

OBJECTIVE

Assessing the impact of introducing preoperative pharmaceutical care consultations by analyzing the severity of prevented medication errors (MEs) and their potential effects on the surgical process.

METHODS

Preoperative pharmaceutical care consultation was implemented in our hospital to assess the preoperative medication management of surgical patients between the pre-anesthesia consultation and the day of surgery. Pharmacists evaluated the appropriateness of medication management based on a consensus multidisciplinary institutional protocol. All errors identified between 2016 and 2020 were analyzed, and their severity and potential impact on surgery were standardized. A list of therapeutic groups was created to prioritize patients for consultations.

RESULTS

During the study period, 3,105 patients attended the consultations and 1,179 MEs were prevented. According to severity, 30.6% of MEs were classified as category E and 26.2% as D. The Number Needed to Treat to prevent a category E or higher ME (indicating potential harm to patients) was 5 patients. About 14.84% of MEs belonged to the prioritized drug groups. One hundred and thirteen errors would have resulted in a surgery delay of more than 24 h, and 175 errors were classified as G-H (irreversible damage).

CONCLUSIONS

This study highlights the effectiveness of pharmaceutical care consultations in preventing MEs and improving surgical outcomes.

Medication review in hospitalised patients to reduce morbidity and mortality

BACKGROUND

A medication review can be defined as a structured evaluation of a patient's medication conducted by healthcare professionals with the aim of optimising medication use and improving health outcomes. Optimising medication therapy though medication reviews may benefit hospitalised patients.

OBJECTIVES

We examined the effects of medication review interventions in hospitalised adult patients compared to standard care or to other types of medication reviews on all-cause mortality, hospital readmissions, emergency department contacts and health-related quality of life.

SEARCH METHODS

In this Cochrane Review update, we searched for new published and unpublished trials using the following electronic databases from 1 January 2014 to 17 January 2022 without language restrictions: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP). To identify additional trials, we searched the reference lists of included trials and other publications by lead trial authors, and contacted experts.

SELECTION CRITERIA

We included randomised trials of medication reviews delivered by healthcare professionals for hospitalised adult patients. We excluded trials including outpatients and paediatric patients.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials, extracted data and assessed risk of bias. We contacted trial authors for data clarification and relevant unpublished data. We calculated risk ratios (RRs) for dichotomous data and mean differences (MDs) or standardised mean differences (SMDs) for continuous data (with 95% confidence intervals (CIs)). We used the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach to assess the overall certainty of the evidence.

MAIN RESULTS

In this updated review, we included a total of 25 trials (15,076 participants), of which 15 were new trials (11,501 participants). Follow-up ranged from 1 to 20 months. We found that medication reviews in hospitalised adults may have little to no effect on mortality (RR 0.96, 95% CI 0.87 to 1.05; 18 trials, 10,108 participants; low-certainty evidence); likely reduce hospital readmissions (RR 0.93, 95% CI 0.89 to 0.98; 17 trials, 9561 participants; moderate-certainty evidence); may reduce emergency department contacts (RR 0.84, 95% CI 0.68 to 1.03; 8 trials, 3527 participants; low-certainty evidence) and have very uncertain effects on health-related quality of life (SMD 0.10, 95% CI -0.10 to 0.30; 4 trials, 392 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

Medication reviews in hospitalised adult patients likely reduce hospital readmissions and may reduce emergency department contacts. The evidence suggests that mediation reviews may have little to no effect on mortality, while the effect on health-related quality of life is very uncertain. Almost all trials included elderly polypharmacy patients, which limits the generalisability of the results beyond this population.

The impact of telepharmacy on hypertension management in the United Arab Emirates

Objectives

To assess the effectiveness of telepharmacy services delivered by community pharmacies in hypertension management and examine its influence on pharmacists' ability to identify drug-related problems (DRPs).

Methods

This was a 2-arm, randomised, clinical trial conducted among 16 community pharmacies and 239 patients with uncontrolled HTN in the U.A.E over a period of 12 months. The first arm (n=119) received telepharmacy services and the second arm (n=120) received traditional pharmaceutical services. Both arms were followed up to 12 months. Pharmacists self-reported the study outcomes, which primarily were the changes in SBP and DBP from baseline to 12-month meeting. Blood pressure readings were taken at baseline, 3, 6, 9, and 12 months. Other outcomes were the mean knowledge, medication adherence and DRP incidence and types. The frequency and nature of pharmacist interventions in both groups were also reported.

Results

The mean SBP and DBP differences were statistically significant across the study groups at 3-, 6-, and 9-month follow-up and 3-, 6-, 9-, 12- month follow-up, respectively. In detail, the mean SBP was reduced from 145.9 mm Hg in the intervention group (IG) and 146.7 mm Hg in the control group (CG) to 124.5, 123.2, 123.5, and 124.9 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the IG and 135.9, 133.8, 133.7, and 132.4 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the CG. The mean DBP was reduced from 84.3 mm Hg in IG and 85.1 mm Hg in CG to 77.6, 76.2, 76.1, and 77.8 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the IG and 82.3, 81.5, 81.5, and 81.9 mm Hg at 3-, 6-, 9-, and 12-month follow-up in the CG. Medication adherence and knowledge of participants in the IG towards hypertension were significantly improved. The DRP incidence and DRPs per patient identified by pharmacists in the intervention and control groups were 2.1% versus 1.0% (p=0.002) and 0.6 versus 0.3 (p=0.001), respectively. The total numbers of pharmacist interventions in the IG and CG were 331 and 196, respectively. The proportions of pharmacist interventions related to patient education, cessation of drug therapy, adjustment of drug dose, and addition of drug therapy across the IG and CG were 27.5% versus 20.9%, 15.4% versus 18.9%, 14.5% versus 14.8%, and 13.9% versus 9.7%, respectively (all with p<0.05).

Conclusion

Telepharmacy may have a sustained effect for up to 12 months on blood pressure of patients with hypertension. This intervention also improves pharmacists' ability to identify and prevent drug-related problems in community setting.

The impact of clinical pharmacist-physician communication on reducing drug-related problems: a mixed study design in a tertiary teaching Hospital in Xinjiang, China

Background

The incidence of drug-related problems (DRPs) has caused serious health hazards and economic burdens among polymedicine patients. Effective communication between clinical pharmacists and physicians has a significant impact on reducing DRPs, but the evidence is poor. This study aimed to explore the impact of communication between clinical pharmacists and physicians on reducing DRPs.

Methods

A semistructured interview was conducted to explore the communication mode between clinical pharmacists and physicians based on the interprofessional approach of the shared decision-making model and relational coordination theory. A randomized controlled trial (RCT) was used to explore the effects of communication intervention on reducing DRPs. Logistic regression analysis was used to identify the influencing factors of communication.

Results

The mode of communication is driven by clinical pharmacists between clinical pharmacists and physicians and selectively based on different DRP types. Normally, the communication contents only cover two (33.8%) types of DRP contents or fewer (35.1%). The communication time averaged 5.8 minutes. The communication way is predominantly face-to-face (91.3%), but telephone or other online means (such as WeChat) may be preferred for urgent tasks or long physical distances. Among the 367 participants, 44 patients had DRPs. The RCT results indicated a significant difference in DRP incidence between the control group and the intervention group after the communication intervention (p = 0.02), and the incidence of DRPs in the intervention group was significantly reduced (15.6% vs. 0.07%). Regression analysis showed that communication time had a negative impact on DRP incidence (OR = 13.22, p < 0.001).

Conclusion

The communication mode based on the interprofessional approach of the shared decision-making between clinical pharmacists and physicians in medication decision-making could significantly reduce the incidence of DRPs, and the length of communication time is a significant factor. The longer the communication time is, the fewer DRPs that occur.

Trial registration

The COVID-19 Pandemic and Patient Safety Culture: A Cross-Sectional Study among Community Pharmacies in Jordan

The COVID-19 pandemic has dramatically imposed stressful conditions that may impact the ability of healthcare staff to provide safe and effective care. Research on patient safety culture among community pharmacies during the pandemic is limited. This study aimed to assess the patient safety culture among community pharmacies in Jordan during the COVID-19 pandemic. Pharmacists and pharmacy assistants from 450 community pharmacies were approached through online means, with 378 answering the questionnaire written in Arabic that had been adapted from the Community Pharmacy Survey on Patient Safety Culture (PSOPSC). This study showed that various patient safety standards were addressed to a high degree during the COVID-19 pandemic, as represented by the high positive response rate (PRR) measures that were mainly observed in the dimensions “Teamwork” (90.1%), “Patient Counseling” (85.2%), and “Staff Training and Skills” (82.7%). Furthermore, significantly higher PRR scores for the “Teamwork”, “Staffing, Work Pressure, and Pace”, “Response to Mistakes”, “Organizational Learning—Continuous Improvement”, and “Overall Perceptions of Patient Safety” dimensions were observed among participants who worked in independent pharmacies than those who worked in chain pharmacies. Despite an overall positive patient safety culture in the current context of community pharmacies in Jordan during the COVID-19 pandemic, pitfalls were observed in the “Staffing, Work Pressure, and Pace” dimension.
