Correlation Between Reduced Daily Living Competence and the Risk of Postoperative Delirium in Orthopedics and Trauma Surgery

Background/Objectives: Postoperative delirium is a prevalent and serious complication among elderly patients following surgical procedures. Prior research indicates that reduced competence in daily living, as evidenced by limitations in performing Activities of Daily Living (ADL), is directly associated with reduced patient mobility. This study aimed to investigate the potential role of preoperative mobility as a risk factor for the development of postoperative delirium. Methods: To assess preoperative mobility, a comprehensive geriatric evaluation of daily living competence was conducted. This included the Katz Index of Independence in ADL, which assessed basic daily activities over the preceding 14 days, and the Instrumental Activities of Daily Living Scale (IADL). Postoperatively, delirium monitoring was performed twice daily for seven days using validated delirium screening tools, including the Nursing Delirium Screening Scale, the Confusion Assessment Method, and the 4ATest. Results: A significant correlation was observed between the incidence of delirium and the IADL scores in all patients, with p < 0.001 for men and p = 0.001 for women. Among emergency patients, the Katz Index scores significantly differed between those who developed delirium and those who did not (p = 0.015). Additionally, a significant correlation was found between the Katz Index and the incidence of delirium in both groups (p < 0.001). Conclusions: The findings of this study emphasize the necessity of preoperative geriatric assessment using tools such as the Katz Index or IADL to identify patients at risk of delirium. The results confirm the importance of enhanced postoperative monitoring for potential delirium. For elective patients, prehabilitation should be considered when reduced daily living competence is identified. For emergency patients, immediate postoperative interventions, including intensive mobilization and orthogeriatric co-management, are recommended.

[Geriatric traumatological rounds in a primary care hospital]

Geriatric traumatological rounds (GTR) with representatives of several disciplines are a challenge in the setting of primary care hospitals with limited resources. The GTR were started with only an experienced traumatologist and a geriatrician in 2019. Routine quality control data showed a reduction of the frequency of cardiac failure and mortality after the start of the GTR. Therefore, even the minimum variant of GTR with the focus on the differential diagnosis of falls and adequate drug treatment appears to be beneficial for the patient. Special attention is given to the medical treatment of cardiac failure, pulmonary diseases, osteoporosis, psychiatric disorders and anemia. Vitamin B12 and folate deficiency are substituted. When anticoagulants or platelet aggregation inhibitors are indicated, they are resumed early. Potentially inadequate drugs for older patients are avoided. Doses of many drugs used in geriatric patients must be adjusted to a reduced renal function often present in old age. Frequent electrolyte abnormalities are diagnosed and adequately treated.

Clinical-pharmacological drug information center of Hannover Medical School: experiences and analysis from a tertiary care university hospital

Drug information centers (DICs) are institutions dedicated to provide objective, independent, and up-to-date information on drugs and their rational use. To overcome the lack of recent DIC reports from central Europe, we analyzed all queries (n = 594) submitted to the DIC run by the Institute for Clinical Pharmacology of Hannover Medical School between October 2018 and April 2022. Approximately one in three queries (31.1%; 185/594) was submitted by internists. 82.8% (492/594) of the queries were patient-specific, while the remaining 17.2% (102/594) were general queries. Adverse drug reactions (ADRs), indications/contraindications, and pharmacodynamic interactions (PDIs) represented the three most frequently addressed query categories, being involved in 44.8% (266/594), 43.3% (257/594), and 34.3% (204/594) of all queries, respectively (assignment of more than one category per query was possible). As compared to general queries, patient-specific queries were statistically significantly more often related to ADRs, PDIs, and pharmacokinetic interactions (PKIs) (ADRs: 35.3% vs. 46.7%, P = 0.034; PDIs: 14.7% vs. 38.4%, P < 0.001; PKIs: 20.6% vs. 31.5%, P = 0.028). To demonstrate the complexity of queries submitted to the clinical-pharmacological DIC, we present and comment on an illustrative selection of queries.

Look-alikes, sound-alikes: Three cases of insidious medication errors

Physicians should be aware of look-alike/sound-alike (LASA) drug names. Clearly legible drug prescriptions, preferably via electronic drug prescription systems, and the use of Tall Man lettering may help to prevent LASA medication errors.
