Reduced prevalence of drug-related problems in psychiatric inpatients after implementation of a pharmacist-supported computerized physician order entry system - a retrospective cohort study.

Introduction: In 2021, a computerized physician order entry (CPOE) system with an integrated clinical decision support system (CDSS) was implemented at a tertiary care center for the treatment of mental health conditions in Lübeck, Germany. To date, no study has been reported on the types and prevalence of drug-related problems (DRPs) before and after CPOE implementation in a psychiatric inpatient setting. The aim of this retrospective before-and-after cohort study was to investigate whether the implementation of a CPOE system with CDSS accompanied by the introduction of regular medication plausibility checks by a pharmacist led to a decrease of DRPs during hospitalization and unsolved DRPs at discharge in psychiatric inpatients. Methods: Medication charts and electronic patient records of 54 patients before (cohort I) and 65 patients after (cohort II) CPOE implementation were reviewed retrospectively by a clinical pharmacist. All identified DRPs were collected and classified based on 'The PCNE Classification V9.1', the German database DokuPIK, and the 'NCC MERP Taxonomy of Medication Errors'. Results: 325 DRPs were identified in 54 patients with a mean of 6 DRPs per patient and 151.9 DRPs per 1000 patient days in cohort I. In cohort II, 214 DRPs were identified in 65 patients with a mean of 3.3 DRPs per patient and 81.3 DRPs per 1000 patient days. The odds of having a DRP were significantly lower in cohort II (OR=0.545, 95% CI 0.412-0.721, p<0.001). The most frequent DRP in cohort I was an erroneous prescription (n=113, 34.8%), which was significantly reduced in cohort II (n=12, 5.6%, p<0.001). During the retrospective in-depth review, more DRPs were identified than during the daily plausibility analyses. At hospital discharge, patients had significantly less unsolved DRPs in cohort II than in cohort I. Discussion: The implementation of a CPOE system with an integrated CDSS reduced the overall prevalence of DRPs, especially of prescription errors, and led to a smaller rate of unsolved DRPs in psychiatric inpatients at hospital discharge. Not all DRPs were found by plausibility analyses based on the medication charts. A more interactive and interdisciplinary patient-oriented approach might result in the resolution of more DRPs.

Short and mid-term impact of community pharmacy-based medication reviews on medication- and patient-related outcomes in Germany.

OBJECTIVE: To assess the effect of a routine medication review service in German community pharmacies (ATHINA) on drug-related problems (DRPs) and patient-related outcomes. MATERIALS AND METHODS: From 2015 to 2017, ATHINA patients were invited by their pharmacists to participate in a prospective, observational trial, meaning that they needed to attend to a follow-up visit (T2) 3 - 6 months after the routine ATHINA baseline (T0) and concluding visit (T1) to assess implementation rates of the pharmacists' interventions. Moreover, they were asked to fill in 2 surveys on drug treatment-related quality of life and satisfaction with the amount of information received about medicines at T0, T1, and T2. RESULTS: Of 132 recruited patients, 115 completed T2. At T0, pharmacists documented a DRP or information need for 114 of 115 patients. About half of these issues were resolved leading to 43/115 patients without any DRP or information need at T1 and 50/115 patients without any DRP or information need at T2 (i.e., absolute reduction by 42.6%, p < 0.001). Also, the number of patients who felt that their daily life was not impaired at all or only very slightly by their drug treatment increased from 54.7% (58/106) at T0 to 67.6% (73/108, p = 0.011) at T2. While the overall satisfaction score with the amount of information on medicines increased from 10.2 ± 5.5 at T0 over 14.6 ± 3.8 (T1) to 15.4 ± 3.1 (T2, p < 0.001), this increase did not correlate with reduced information needs. CONCLUSION: The results suggest that the intervention improves medication- and patient-related outcomes. However, causal relationships are still questionable.

Structure and Content of Drug Monitoring Advices Included in Discharge Letters at Interfaces of Care: Exploratory Analysis Preceding Database Development.

BACKGROUND: Inadequate drug monitoring of drug therapy after hospital discharge facilitates adverse drug events and preventable hospital readmissions. OBJECTIVE: This study aimed to analyze the structure and content of drug monitoring advices of a representative sample of discharge letters as a basis for future electronic information systems. METHODS: On 2 days in November 2016, all discharge letters of 3 departments of a university hospital were extracted from the hospital information system. The frequency, content, and structure of drug monitoring advices in discharge letters were investigated and compared with the theoretical monitoring requirements expressed in the corresponding summaries of product characteristics (SmPC). The quality of the drug monitoring advices in the discharge letters was rated with the domains of an adapted systematic instructions for monitoring (SIM) score. RESULTS: In total, 154 discharge letters were analyzed containing 1180 brands (240 active pharmaceutical substances), of which 50.42% (595/1180) could theoretically be amended with a monitoring advice according to the SmPC. In reality, 40 discharge letters (26.0%, 40/154) contained a total of 66 monitoring advices for 57 brands (4.83%, 57/1180), comprising 18 different monitoring parameters. Drug monitoring advices only addressed mean 1.9 (SD 0.8) of the 7 domains of the SIM score and frequently did not address reasons for monitoring (86%, 57/66), the timing of monitoring, that is, the start (76%, 50/66), the frequency (94%, 63/66), the stop (95%, 63/66), and how to react (83%, 55/66). CONCLUSIONS: Drug monitoring advices were mostly absent in discharge letters and a gold standard for appropriate drug monitoring advices was lacking. Hence, more effort should be put in the development of tools that facilitate easy presentation of clinically meaningful drug monitoring advices at the point of care.

Guidance on how to achieve comprehensible patient information leaflets in four steps.

Comprehensible information leaflets can improve a patient's knowledge. However, in clinical studies leaflets are often introduced without meticulously verifying their comprehensibility. In an attempt to provide a feasible guidance on how to design comprehensible leaflets we complied and evaluated an easy-to-use development procedure. In January 2015, a literature search was performed to identify evidence for readily available quality assurance strategies as a starting point for a standardized strategy to develop and validate written patient information. The suggested development strategy is a consecutive four-step procedure that comprised already validated distinct quality assessments: (i) an initial requirement analysis specifying the needs and constraints of the target population and evidence-based preparation of the leaflets, (ii) a readability assessment, (iii) the Suitability Assessment of Materials instrument and (iv) iterative consumer test in the target population. The consecutive combination of pertinent and previously validated quality assessments provides an easy-to-use guidance on how to create comprehensibly written patient information, particularly for small-scale research projects with time and money constraints.
