Discrepancies between electronic prescribing systems and patients' actual use of medicines can result in adverse events and medication errors and have serious consequences for the patients. The discrepancies can be identified when performing a thorough medication reconciliation. Computerized health care systems throughout the Danish health care sector are integrated with the Shared Medication Record (SMR). In the SMR, current medication and medication prescriptions are registered. The aim of this study was to evaluate the number and types of discrepancies between medications listed in the SMR and an updated medication list, obtained through a thorough medication reconciliation, for patients admitted in Danish hospitals. Pharmacists listed the number and type of discrepancies for 412 patients. A total of 1,004 discrepancies were registered, with a mean number of 2.4 medication discrepancies per patient. For 25% (n = 101) of the patients, no discrepancies were found, 20% (n = 86) had one discrepancy, and 16% (n = 66) had five or more discrepancies. More than 50% of the patients had one or more medications in the SMR that the patient did not administer, and 12.6% used medications that were not listed in the SMR. This shows that the SMR should not be used as the only source of information when recording medication history.

Empiric antimicrobials are frequently utilized in the pre-engraftment phase after hematopoietic cell transplantation (HCT). Recent evidence suggests an increased risk of acute kidney injury (AKI) from combination of vancomycin with piperacillin/tazobactam; however, this has not specifically been evaluated in the HCT population. A single-center, retrospective review was conducted from 2011 to 2017 on 110 autologous and 60 allogeneic HCT patients with the primary objective of comparing incidence of AKI for those who received vancomycin with piperacillin/tazobactam versus vancomycin with cefepime in the pre-engraftment phase. Demographics and outcomes were compared for all patients who received vancomycin with piperacillin/tazobactam versus vancomycin with cefepime as well as within the autologous and allogeneic subgroups. The primary endpoint of incidence of AKI, defined as increase in serum creatinine by .3 mg/dL or >50% from baseline (whichever was larger), was significantly higher for those who received vancomycin with piperacillin/tazobactam versus cefepime for the overall cohort (68% versus 27%; P < .001) resulting in an odds ratio (OR) of 5.16 (95% confidence interval [CI], 2.5 to 10.5) when adjusting for hypotension. Results were similar within the autologous (59% versus 22%; P < .001; OR, 4.63; 95% CI, 1.85 to 11.6) and allogeneic (79% versus 39%; P= .0021; OR, 5.41; 95% CI, 1.60 to 18.3) subgroups. Within the overall cohort between those who received vancomycin with piperacillin/tazobactam versus cefepime the time to onset of AKI was more commonly within 48 hours of concomitant antimicrobial use (53% versus 26%; P= .012), whereas resolution of AKI by discharge date was not different (39% versus 26%; P= .23). No difference in percentage of patients requiring at least 1 session of dialysis, duration of hospital stay, or 30-day mortality was found between overall cohorts. Further studies of HCT patients are warranted to fully elucidate the risk of various combination antimicrobial regimens on renal outcomes.

Background Disagreement among healthcare professionals on the clinical relevance of drug-related problems can lead to suboptimal treatment and increased healthcare costs. Elderly patients with chronic non-cancer pain and comorbidity are at increased risk of drug related problems compared to other patient groups due to complex medication regimes and transition of care. Objective To investigate the agreement among healthcare professionals on their classification of clinical relevance of drug-related problems in elderly patients with chronic non-cancer pain and comorbidity. Setting Multidisciplinary Pain Centre, Rigshospitalet, Copenhagen, Denmark. Method A pharmacist performed medication review on elderly patients with chronic non-cancer pain and comorbidity, identified their drug-related problems and classified these problems in accordance with an existing categorization system. A five-member clinical panel rated the drug-related problems' clinical relevance in accordance with a five-level rating scale, and their agreement was compared using Fleiss' κ. Main outcome measure Healthcare professionals' agreement on clinical relevance of drug related problems, using Fleiss' κ. Results Thirty patients were included in the study. A total of 162 drug related problems were identified, out of which 54% were of lower clinical relevance (level 0-2) and 46% of higher clinical relevance (level 3-4). Only slight agreement (κ = 0.12) was found between the panellists' classifications of clinical relevance using a five-level rating scale. Conclusion The clinical pharmacist identified drug related problems of lower and higher clinical relevance. Poor overall agreement on the severity of the drug related problems was found among the panelists.
