Psychedelic Therapy: A Primer for Primary Care Clinicians-Historical Perspective and Overview.

BACKGROUND: Psychedelic drugs have recently emerged as plausibly effective pharmacological agents for the management of depression, anxiety, and other neuropsychiatric conditions, including those that are treatment-resistent. The latter half of the 20th century marked a revolution in the treatment of mental illnesses, exemplified by the introduction of selective serotonin reuptake inhibitors and other pharmacological agents. Nevertheless, mental illness remains a major public health crisis, affecting nearly one billion individuals worldwide. AREAS OF UNCERTAINTY: Because of the decades-long status of several psychedelics as Schedule I drugs, there have not been very many large, double-blind, randomized controlled trials of psychedelics. Owing to small sample sizes, there may be rare yet serious adverse events that have not been reported in the clinical trials thus far. THERAPEUTIC ADVANCES: Esketamine, a dissociative hallucinogen drug, was approved for the management of major depressive disorder by the Food and Drug Administration in 2019. As of January 2024, two Phase III trials of 3,4-methylenedioxymethamphetamine (MDMA), a synthetic drug that inhibits the serotonin transporter, have been completed; the results indicate that MDMA is superior to existing pharmacological treatments for post-traumatic stress disorder. A phase III trial of psilocybin, a naturally occurring serotonin receptor partial agonist, is currently underway. The following series details the current state of research in psychedelic therapeutics, including lysergic acid diethylamide (LSD), N-N-dimethyltryptamine (DMT) and ayahuasca, psilocybin, ibogaine, MDMA, and ketamine. LIMITATIONS: While initial clinical trials of psychedelics for depression were very promising, trials of psilocybin with larger sample sizes (100+ participants) suggest that its remission rate is 25%-29%. This is about the same as the remission rate of antidepressants, which is roughly 30% according to the landmark STAR*D trial. CONCLUSIONS: Psychedelic drugs and structural derivatives offer a great deal of promise for the management of a wide range of psychiatric morbidities. It is imperative that clinicians become familiar with these novel agents and learn how to integrate psychedelic therapy with the rest of their care through open communication and referral.

Psychedelic Therapy: A Primer for Primary Care Clinicians-Lysergic Acid Diethylamide (LSD).

BACKGROUND: Lysergic acid diethylamide (LSD) is a hallucinogenic agent. In the mid-20th century, it was used to augment psychoanalysis and to treat alcohol use disorder. However, LSD was banned in 1970 in part because of concerns that it could bring about or exacerbate mental illness. Its therapeutic potential remains incompletely understood. AREAS OF UNCERTAINTY: While uncontrolled recreational use of LSD can, in rare instances, lead to long-term psychosis, adverse events in clinical trials of LSD, such as anxiety, headache, and nausea, have almost always been mild and transient. Serious adverse events, such as intense panic, suicidal ideation, and psychosis, were reported in either none or very few of the participants. However, patient selection criteria, optimal dosing strategy, and appropriate clinical follow-up guidelines remain to be established. THERAPEUTIC ADVANCES: Preliminary data suggest that LSD may be effective for the management of alcohol use disorder, anxiety, and depression. In trials of LSD for treating anxiety and depression associated with life-threatening illnesses, 77% of participants demonstrate durable relief at 1 year post-treatment. Top-line data from a large-scale phase IIb trial (n = 198) indicate that 50% of participants experience remission from generalized anxiety disorder after a single 100 µg dose of LSD. According to a meta-analysis of RCTs on LSD from the mid-20th century, single-dose regimens of LSD significantly improve alcohol use disorder (P < 0.0003) with an odds ratio (OR) of 1.96. LIMITATIONS: Only one large-scale clinical trial (>50 participants) has been conducted on LSD in the contemporary era of psychedelic research. Further studies with large sample sizes are needed to explore potential clinical applications. CONCLUSIONS: Preliminary data suggest that LSD may be one of the most potent treatments for anxiety in patients both with and without a life-threatening illness. LSD may also be beneficial for treating depression and substance use disorders.

Psychedelic Therapy: A Primer for Primary Care Clinicians-Ibogaine.

BACKGROUND: Ibogaine is a plant-derived alkaloid that has been used for thousands of years in rites of passage and spiritual ceremonies in West-Central Africa. In the West, it has primarily been used and studied for its anti-addictive properties and more recently for other neuropsychiatric indications, including post-traumatic stress disorder, depression, anxiety, and traumatic brain injury. AREAS OF UNCERTAINTY: Ibogaine requires careful patient screening and monitoring because of significant safety issues. There is potential for cardiotoxicity (prolonged QT interval); without rigorous screening, fatal arrhythmias may occur. However, preliminary research suggests that co-administration of ibogaine with magnesium may mitigate cardiotoxicity. Additionally, ibogaine may have dangerous interactions with opiates, so patients who receive ibogaine treatment for opioid use disorder must withdraw from long-acting opioids. Other potential concerning effects of ibogaine include rare incidences of mania or psychosis. Anticipated transient effects during ibogaine treatment can include ataxia, tremors, and gastrointestinal symptoms. THERAPEUTIC ADVANCES: Robust effects after a single treatment with ibogaine have been reported. In open-label and randomized controlled trials (RCTs), ibogaine reduces heroin and opioid cravings by upwards of 50%, up to 24 weeks after the treatment. An observational study of 30 Special Operations Forces veterans with mild traumatic brain injury reported that 86% were in remission from post-traumatic stress disorder, 83% from depression, and 83% from anxiety, one month after a single-dose ibogaine treatment. LIMITATIONS: Although there are several observational and open-label studies, there is only a single double-blind, placebo-controlled RCT on ibogaine. More RCTs with large sample sizes must be conducted to support ibogaine's safety and efficacy. CONCLUSIONS: Given the promising preliminary findings, ibogaine could potentially fill a much-needed gap in treatments for challenging conditions, including opioid dependence. Ibogaine's remarkable effects in traditionally treatment-resistant, combat-exposed individuals hints at its potential in broader populations with physical and psychological trauma.

Psychedelic Therapy: A Primer for Primary Care Clinicians-N,N-Dimethyltryptamine and Ayahuasca.

BACKGROUND: N,N-dimethyltryptamine (DMT) is a naturally occurring serotonergic psychedelic found in natural plants around the globe. As the main psychoactive component in ayahuasca, which also contains monoamine oxidase inhibitors, DMT has been consumed as plant-based brew by indigenous peoples for centuries. Further research is required to delineate the therapeutic utility of DMT. AREAS OF UNCERTAINTY: Although previous research has shown that DMT is synthesized endogenously, it may not be produced at physiologically relevant concentrations. Additionally, the phenomenological similarities between the DMT-induced state and near-death experiences led to the popular hypothesis that endogenous DMT is released during the dying process. However, this hypothesis continues to be debated. Generally, DMT and ayahuasca seem to be physiologically and psychiatrically safe, although ayahuasca is known to cause transient vomiting. THERAPEUTIC ADVANCES: A double-blind, randomized controlled trial showed that, within 1 week, ayahuasca causes remission in 36% of patients with treatment-resistant depression. According to top-line results from a recent phase IIa trial, 57% of patients with major depressive disorder experienced remission 12 weeks after receiving a single intravenous dose of DMT. LIMITATIONS: There has only been a single published double-blind randomized controlled trial on ayahuasca and 2 on DMT. All clinical trials have had small sample sizes (≤34 participants). DMT requires further research to understand its therapeutic and clinical potential as a psychedelic. CONCLUSIONS: Preliminary evidence indicates that ayahuasca and DMT may be more effective than existing antidepressants for treating major depressive disorder and treatment-resistant depression.

Psychedelic Therapy: A Primer for Primary Care Clinicians-3,4-Methylenedioxy-methamphetamine (MDMA).

BACKGROUND: After becoming notorious for its use as a party drug in the 1980s, 3,4-methylenedioxy-methampetamine (MDMA), also known by its street names "molly" and "ecstasy," has emerged as a powerful treatment for post-traumatic stress disorder (PTSD). AREAS OF UNCERTAINTY: There are extensive data about the risk profile of MDMA. However, the literature is significantly biased. Animal models demonstrating neurotoxic or adverse effects used doses well beyond the range that would be expected in humans (up to 40 mg/kg in rats compared with roughly 1-2 mg/kg in humans). Furthermore, human samples often comprise recreational users who took other substances in addition to MDMA, in uncontrolled settings. THERAPEUTIC ADVANCES: Phase III clinical trials led by the Multidisciplinary Association for Psychedelic Studies (MAPS) have shown that MDMA-assisted psychotherapy has an effect size of d = 0.7-0.91, up to 2-3 times higher than the effect sizes of existing antidepressant treatments. 67%-71% of patients who undergo MDMA-assisted psychotherapy no longer meet the diagnostic criteria for PTSD within 18 weeks. We also describe other promising applications of MDMA-assisted psychotherapy for treating alcohol use disorder, social anxiety, and other psychiatric conditions. LIMITATIONS: Thus far, almost all clinical trials on MDMA have been sponsored by a single organization, MAPS. More work is needed to determine whether MDMA-assisted therapy is more effective than existing nonpharmacological treatments such as cognitive behavioral therapy. CONCLUSIONS: Phase III trials suggest that MDMA is superior to antidepressant medications for treating PTSD. Now that MAPS has officially requested the Food and Drug Administration to approve MDMA as a treatment for PTSD, legal MDMA-assisted therapy may become available as soon as 2024.

Psychedelic Therapy: A Primer for Primary Care Clinicians-The Strengths, Weaknesses, Opportunities, and Threats of Psychedelic Therapeutics.

The reviews in this special edition have presented a primer on the state of the literature for 7 different psychedelic compounds and their plausible roles in medicine. In a common format underscoring strengths, weakness, opportunities, and threats (SWOT), this article addresses how psychedelic compounds fit into the broader health care landscape for indicated conditions. Historically, psychiatric pathologies have been treated with small-molecule compounds that have limited effect sizes and carry a variety of adverse effect profiles. Psychedelic medicines offer the opportunity to provide more potent and rapidly acting treatments. It is crucial to note that this is an emerging field of medicine, and only one of these compounds (esketamine) is currently Food and Drug Administration-approved for depression. The other compounds discussed are investigational, and this discussion is both imaginative and prospective in nature.

Psychedelic Therapy: A Primer for Primary Care Clinicians-Ketamine.

BACKGROUND: Ketamine, an arylcyclohexylamine dissociative anesthetic agent, has evolved into a versatile therapeutic. It has a rapid-onset, well-understood cardiovascular effects and a favorable safety profile in clinical use. Its enantiomeric compound, esketamine, was approved by the Food and Drug Administration in 2019 for both treatment-resistant depression and major depressive disorder with suicidal ideation. AREAS OF UNCERTAINTY: Research indicates dose-dependent impacts on cognition, particularly affecting episodic and working memory following both acute administration and chronic use, albeit temporarily for the former and potentially persistent for the latter. Alongside acute risks to cardiovascular stability, ketamine use poses potential liver toxicity concerns, especially with prolonged or repeated exposure within short time frames. The drug's association with "ketamine cystitis," characterized by bladder inflammation, adds to its profile of physiological risks. THERAPEUTIC ADVANCES: Data demonstrate a single intravenous infusion of ketamine exhibits antidepressant effects within hours (weighted effect size averages of depression scores (N = 518) following a single 0.5 mg/kg infusion of ketamine is d = 0.96 at 24 hours). Ketamine is also effective at reducing posttraumatic stress disorder (PTSD) symptom severity following repeated infusions (Clinician-Administered PTSD Scale scores: -11.88 points compared with midazolam control). Ketamine also decreased suicidal ideation in emergency settings (Scale for Suicidal Ideation scores: -4.96 compared with midazolam control). Through its opioid-sparing effect, ketamine has revolutionized postoperative pain management by reducing analgesic consumption and enhancing recovery. LIMITATIONS: Many studies indicate that ketamine's therapeutic effects may subside within weeks. Repeated administrations, given multiple times per week, are often required to sustain decreases in suicidality and depressive symptoms. CONCLUSIONS: Ketamine's comprehensive clinical profile, combined with its robust effects on depression, suicidal ideation, PTSD, chronic pain, and other psychiatric conditions, positions it as a substantial contender for transformative therapeutic application.

Psychedelic Therapy: A Primer for Primary Care Clinicians-Psilocybin.

BACKGROUND: The primary psychoactive drug in magic mushrooms, psilocybin, induces profound alterations in consciousness through the 5-HT2A receptor. This review consolidates current research findings to elucidate the pharmacology, safety profile, and clinical applications of psilocybin. AREAS OF UNCERTAINTY: Despite initial concerns that psilocybin could cause psychosis, contemporary research has demonstrated that psilocybin is generally safe. The most common adverse effects are nausea and headache, yet both tend to be transient. Serious adverse events can generally be avoided in controlled settings such as clinical trials. However, in the largest clinical trial to date, there were a total of 7 reported cases of suicidal ideation, up to 12 weeks after receiving a single 25 mg dose of psilocybin. That being said, all 7 cases did not respond to the treatment. Although selective serotonin reuptake inhibitors may blunt the hallucinogenic qualities of psilocybin, preliminary research suggests that they may enhance its antidepressant effects. THERAPEUTIC ADVANCES: In clinical trials, psilocybin has shown promise for treating major depressive disorder and treatment-resistant depression. Initial studies indicated that 42%-57% of patients underwent remission after psilocybin-assisted therapy, which suggests that psilocybin is more effective than existing antidepressant medications. Clinical data have also demonstrated that psilocybin can manage substance use disorders and end-of-life anxiety with clinical outcomes that are sustained for months and sometimes years after 1 or 2 doses. LIMITATIONS: However, larger Phase II trials with more than 100 depressed participants have shown a much smaller remission rate of 25%-29%, though these studies still observed that psilocybin causes a significant reduction in depressive symptoms. CONCLUSIONS: Aside from ketamine, psilocybin is the most clinically well-researched psychedelic drug, with trials that have enrolled hundreds of participants and multiple therapeutic applications. Phase III trials will determine whether psilocybin lives up to the promise that it showed in previous clinical trials.

Utility of Thrombectomy in Nonagenarians: A Scoping Review.

BACKGROUND: Mechanical thrombectomy represents a mainstay of management for acute ischemic stroke in the setting of large vessel occlusion. However, there are no clinical practice guidelines defining the role of thrombectomy at the extremes of age. In this scoping review, we aimed to summarize the existing medical and neurosurgical literature pertaining to mechanical thrombectomy in nonagenarians. The PubMed database was queried using the following terms and relevant citations assessed: "thrombectomy nonagenarian," "thrombectomy age 90," "stroke nonagenarian," and "ischemic stroke thrombectomy." Common measurable outcomes, including mortality, modified Rankin scale (mRS) score, and Thrombolysis in Cerebral Infarction (TICI) scale score, were utilized to compare results. SUMMARY: Thrombectomy was shown to improve functional outcomes in all eight of the studies included in the analysis. Mortality was assessed in only two reported studies, and thrombectomy was shown to provide a mortality benefit in one study amongst patients for whom first-pass reperfusion was achieved. Other outcomes of reported interest included greater early neurologic recovery at discharge and improved functional outcomes at 90 days amongst nonagenarians who underwent thrombectomy as compared to those who received thrombolytic therapy alone. Nonagenarians with good functional status at baseline were the most likely to have favorable outcomes. KEY MESSAGES: Mechanical thrombectomy improves outcomes among nonagenarians presenting with acute ischemic stroke due to large vessel occlusion. Further large-scale prospective studies are warranted to optimize patient selection and develop clinical practice guidelines specific to this important patient demographic.

Inadvertent Intrathecal Administration of Digoxin, with Review of the Literature.

While the systemic effects of digoxin have been studied, limited data exist on the effects of neuraxial administration. Prior case reports document how digoxin and lidocaine share indistinguishable vials and were inadvertently stocked together in spinal and epidural anesthesia kits, necessitating a need for further implementation of safety measures. Here, we report the poor progression and brain death of a postpartum woman after accidental administration of intrathecal digoxin during a routine elective cesarean section (C-section). It is imperative that quality improvement and safety measures are taken to avoid the recurrence of this medical error.

Endovascular thrombectomy in the setting of occult cerebral artery aneurysm: Reducing the risk of iatrogenic rupture.

Cerebral artery aneurysms are present in up to 10% of ischemic stroke patients, often within or adjacent to the occluded vessel. In some cases, the approach to intervention may need to be modified based on the size and location of the aneurysm. We describe a 99-year-old female with a known history of cerebral aneurysm who underwent successfully mechanical thrombectomy of a right middle cerebral artery thrombus; an 8-mm aneurysm involving the right M1 bifurcation was identified only on post-procedural digital subtraction angiography. In addition, we discuss strategies to reduce the risk of iatrogenic aneurysm rupture in the setting of endovascular thrombectomy.

Vertigo and Cytotoxic Lesions of the Corpus Callosum: Report with Review of the Literature.

BACKGROUND: The term cytotoxic lesions of the corpus callosum (CLOCCs) encompasses the entity reversible splenial lesion syndrome (RESLES). RESLES typically presents with altered levels of consciousness, seizures, and delirium and is distinguished radiographically by reversible focal lesions of the splenium of the corpus callosum. This disease pathology is associated with withdrawal of antiepileptic medications, infections, metabolic disturbance, or high-altitude cerebral edema. METHODS: We presented an otherwise healthy 72-year-old female that was consulted for an episode of isolated vertigo lasting four hours. Initial workup included CT head without contrast, CT angiogram head and neck, and MRI brain with and without contrast. The patient experienced recurrent episodes of vertigo at one and four months after initial presentation. An extensive workup at one month included a wide spectrum of laboratory tests and repeat imaging. RESULTS: Noncontrast CT of the head and CT angiogram of the head and neck were reassuring. MRI brain with and without contrast demonstrated hyperintensity in the splenium of the corpus callosum on FLAIR sequencing. A follow-up visit at one month revealed vitamin B12 deficiency and unchanged hyperintensity of the splenium of the corpus callosum. History and workup were negative for typical risk factors associated with RESLES. CONCLUSION: An otherwise healthy patient who presented with an isolated episode of vertigo was discovered to demonstrate radiographic features consistent with RESLES but lacked the common risk factors and typical presentation of RESLES. This case expands the possible clinical presentation of RESLES and highlights the possible relationship between vitamin B12 deficiency and radiographic features of RESLES.

B12 Deficiency and Clinical Presentation in the Setting of Nitric Oxide Use.

B12 deficiency can arise symptomatically from an array of varying pathologies including frank deficiency from strict vegan diets. Other high-risk contributing pathological conditions include chronic alcoholism, autoimmune disease, and chronic gastrointestinal inflammatory disorders, and it is also seen in those with a history of gastric surgery. Additionally, the elderly are at an increased risk as are patients prescribed certain medications. Uncommonly suspected causes of B12 deficiency include the abuse of recreational nitrous oxide (NO) given its interference with cobalt oxidation. Here, we report two cases of hypovitaminosis B12 in association with NO abuse in an effort to highlight an increasingly dangerous trend with recreational use. Importantly, we aim to increase visibility of this malady given that improperly diagnosed neurologic deterioration following NO anesthesia has been shown to become irreversible and may even result in death.

Acute bilateral internal carotid artery occlusion: A novel approach to management of a catastrophic clinical entity.

BACKGROUND: Acute bilateral internal carotid artery occlusion (ABICAO) represents a rare but potentially-lethal clinical entity. Guidelines for management remain to be established. However, emergent intervention is vital to prevent loss of brainstem reflexes and death. PURPOSE: We describe two patients who presented with ABICAO and detail a novel management approach with carotid angioplasty and stent placement. In addition, we review the literature on ABICAO. RESULTS: Two patients presented within a two-week period with marked neurologic deficits. Imaging studies showed ABICAO. The first patient was initially treated with tissue plasminogen activator. No improvement occurred after two days, prompting the medical team to attempt urgent carotid artery angioplasty and stenting. However, the patient continued to deteriorate and died shortly after the intervention. The second patient underwent emergent carotid artery angioplasty and stenting within hours of presentation and recovered with only mild residual neurologic deficits. CONCLUSION: Further research on ABICAO management is required to establish clinical practice guidelines. However, as evidenced by our two patients, endovascular thrombectomy should be performed as early as possible in appropriate candidates; an unfavorable outcome may occur if treatment is delayed. Based on the limited available data, emergent angioplasty and stenting should be considered a first-line intervention for patients presenting with this rare and oft-lethal event.

Delayed Endovascular Thrombectomy for Ischemic Stroke in a Young Woman with No Known Risk Factors: A Case Report.

BACKGROUND National guidelines and consensus statements suggest a 24-hour window for endovascular recanalization in patients presenting with acute ischemic stroke due to large-vessel occlusion. However, the safety and efficacy of extending the window for intervention remains to be definitively established. CASE REPORT A healthy 26-year-old woman presented with headache, left-sided hemiplegia, and rightward gaze palsy 2 days after a minor trauma. Time last known well was approximately 50 hours prior to presentation. Computed tomography angiography revealed dissection of the distal right internal carotid artery and occlusion of the M1 segment of the right middle cerebral artery. Magnetic resonance imaging showed a small area of acute infarct in the right basal ganglia and right insular cortex, but suggested a large ischemic penumbra; this was confirmed with cerebral perfusion analysis. In light of the patient's young age and potential for penumbral salvage, mechanical thrombectomy of an M1 thrombus and stenting of an internal carotid artery dissection were performed nearly 60 hours after the onset of symptoms. The patient demonstrated marked clinical improvement over the following days and was discharged home in excellent condition one week after presentation. Based on our clinical experience and other emerging data, we propose that extension of the 24-hour window for endovascular intervention may improve functional outcomes among select individuals. CONCLUSIONS A 24-hour window for endovascular thrombectomy is appropriate for many patients presenting with acute ischemic stroke. However, in select individuals, extension of the window to 48 hours or beyond may improve functional outcomes.

Large vessel stroke and COVID-19: Case report and literature review.

The clinical signs of coronavirus disease-19 (COVID-19) can be heterogenous because of the diversity of potential organ involvement. We describe a 58-year-old woman who developed new-onset dysarthria and hemiplegia and was found to be COVID-19-positive. This is among the first cases of COVID-19 presenting solely with focal neurologic deficits.

Signals that link energy to reproduction: gastric fill, bulk intake, or caloric intake?

Reproductive processes are inhibited by deficits in the availability of metabolic fuels, and this inhibition increases the chances of survival during energetic challenges and optimizes reproductive success by delaying energetically costly processes until fuels become available. The mechanisms that link energy availability to reproduction are unknown, and thus, in this study we tested the hypothesis that estrous cycles are most sensitive to sensory signals from bulk intake and gastric fill as opposed to signals from caloric intake or the availability of intracellular oxidizable fuels. The caloric content of a standard laboratory chow diet was diluted by 25, 50, or 75% with the largely indigestible fiber, cellulose, and fed to food-deprived, female hamsters throughout day 2 of the estrous cycle (ovulation and estrous behavior normally occur on day 4). The bulk intake/gastric fill hypothesis was not supported because bulk intake increased the more the diet was diluted, whereas the frequency of hamsters showing normal 4-day estrous cycles decreased with diet dilution, along with decreases in caloric intake and in plasma insulin concentrations. Rate of gastric emptying did not change significantly with diet dilution. Although consumption of a diluted diet significantly lengthened the estrous cycle, it did not affect incidence of pregnancy, litter size or pup weight. Thus, when hamsters ingest sufficient energy to support estrous behavior, they fully recover reproductive potential. In summary, neither bulk intake nor gastric fill provides critical signals necessary for reproduction, consistent with the idea that reproduction is primarily responsive fuel availability.

Pica patient, status post gastric bypass, improves with change in medication regimen.

The causes and origins of pica remain unknown and are the source of speculation and heated debate. Bariatric surgery patients are increasingly being observed in eating disorders treatment programs. Often associated with pregnancy, iron deficiency anemia, early development and mental retardation, pica has only recently been noted in post bariatric surgery patients, all of whom presented with pagophagia (eating of ice). Although there is literature detailing the presence of bezoars in gastric bypass patients, the association of pica, bezoars and abnormal eating behavior after bariatric surgery is still not understood completely. We present the case of a patient diagnosed with pica who underwent bariatric surgery due to a specific bezoar causing obstruction, followed by a treatment plan aimed at curbing the impulses. The patient was diagnosed to have a cardboard and paper bezoar causing gastric obstruction, which was removed endoscopically. After incomplete improvement of pica symptoms with treatment including ziprasidone, lorazepam and behavioral therapy, Saphris (asenapine) was introduced resulting in significant and complete resolution.

Undivided attention improves postoperative anesthesia handover recall.

BACKGROUND: For years, undivided attention during the presurgical "timeout" has been utilized as a precaution to ensure patient safety. The information relayed during the timeout is presented in a confirmatory nature rather than a delegation of new information. However, it is a standard of practice in which all members of the operating theater provide their full and undivided attention. Standards of patient care should be contiguous throughout the preoperative, perioperative, and postoperative stages of surgery. In this manner, it is expected that the same undivided attention afforded during the timeout should be maintained when transferring the patient to the postanesthesia care unit. METHODS: In this study, information was collected regarding handover of information during the transfer status postsurgical procedures. Data were collected via observing interactions between the anesthesiologist and the nurse during verbal patient transfers. RESULTS: This study demonstrated that the presence of undivided attention during the handover of a surgical patient in the postanesthesia care unit has a direct correlation with improved recall of the information discussed during handover. CONCLUSION: Focus is on the quantity of information that can be recalled by the transferring nurse, and whether or not undivided attention affects the outcome. Analysis focuses on suggestions to better improve patient safety and recovery when being transferred in an anesthetic setting. The practice of patient handover should be standardized to better improve the safety and quality of medical care.
