Multimodal therapy facilitates a fast-track recovery after surgery - are potential drug-drug interactions of clinical significance in the perioperative period?

Preoperative Deprescribing for Medical Optimization of Older Adults Undergoing Surgery: A Systematic Review

OBJECTIVE

To summarize the evidence for preoperative deprescribing and its effect on postoperative outcomes in older adults undergoing surgery.

DESIGN

Systematic review.

SETTING AND PARTICIPANTS

All available studies.

METHODS

We searched EMBASE, Cumulative Index of Nursing and Allied Health (CINAHL), and PubMed from inception to January 12, 2021. Settings included outpatient settings during the waiting period for surgery (ie, preoperative clinic) through to the preoperative period in the hospital. Participants who were older adults, aged ≥65 years, undergoing planned or emergency surgery with deprescribing or medication-related interventions were included for review.

RESULTS

We identified 3 different methods of deprescribing intervention delivery during the preoperative period: geriatrician-led (n = 2), interdisciplinary team-led (n = 8), and pharmacist-led (n = 6). Outcomes were related to health care utilization, patient outcomes, and medication changes; however, results were difficult to compare because of heterogeneous outcomes within the topics. Overall, results were either positive or neutral.

CONCLUSIONS AND IMPLICATIONS

The evidence for deprescribing during the preoperative period for older adults undergoing surgery is weak because of the heterogeneity of intervention delivery and outcomes, inclusion of nonoperative cases in some studies, and low power. This review highlights the need for future research, which may consider the following: (1) interdisciplinary approach, (2) coordination of deprescribing efforts with primary care provider from the waiting period for surgery up to after hospital discharge, and (3) validated deprescribing criteria such as STOPP/START that is easy to implement. It is important to note that results yielded positive and neutral results, not negative ones, which should reassure clinicians to implement deprescribing for older adults during the surgical period. Additionally, policy initiatives such as integrated electronic medical records or increased reimbursement of deprescribing efforts for primary care providers and/or hospitals should be pursued to prevent adverse postoperative events for this population.

Perioperative Care of Elderly Surgical Outpatients

The ambulatory setting offers potential advantages for elderly patients undergoing elective surgery due to the advancement in both surgical and anesthetic techniques resulting in quicker recovery times, fewer complications, higher patient satisfaction, and reduced costs of care. This review article aims to provide a practical guide to anesthetic management of elderly outpatients. Important considerations in the preoperative evaluation of elderly outpatients with co-existing diseases, as well as the advantages and disadvantages of different anesthetic techniques on a procedural-specific basis, and recommendations regarding the management of common postoperative complications (e.g., pain, postoperative nausea and vomiting [PONV], delirium and cognitive dysfunction, and gastrointestinal dysfunction) are discussed. The role of anesthesiologists as perioperative physicians is important for optimizing surgical outcomes for elderly patients undergoing ambulatory surgery. The implementation of high-quality, evidence-based perioperative care programs for the elderly on an ambulatory basis has assumed increased importance. Optimal management of perioperative pain using opioid-sparing multimodal analgesic techniques and preventing PONV using prophylactic antiemetics are key elements for achieving enhanced recovery after surgery.
