Temporal Trends in Methamphetamine Use in Patients Admitted to the Hospital: A Retrospective Cohort Study.

OBJECTIVES: Although methamphetamine use is common, the scope of methamphetamine use and outcomes for patients admitted to the hospital is unclear. This study aims to identify the prevalence of methamphetamine use from January 2012 to January 2022, coingestions, hospital course, and readmission rate of admitted patients. METHODS: This was a retrospective cohort study conducted on patients admitted to our center with the following inclusions: age older than 18 years, positive/"pending confirm" value for methamphetamine on urine drug screen, and/or an International Classification of Diseases , Tenth Revision , code related to stimulant use disorder as an active issue. Urine drug screen data are reported as methamphetamine +/- and polysubstance (PS) +/-. Patient demographics, admission diagnosis, and hospital course were extracted. Statistical tests used included t tests and Mann-Whitney U tests. RESULTS: A total of 19,159 encounters were included, representing 12,057 unique patients. The median (interquartile range) age was 43 (33-54) years. Of all encounters, 35.3% were methamphetamine + and PS -, and 46.3% were methamphetamine + and PS +. Hospitalizations increased from 883 in 2012 to 2532 in 2021. The median (IQR) hospital stay was 48 (48-120) hours. Of all encounters, 16.8% included an intensive care unit (ICU) admission, and the median ICU stay was 42 (21-87) hours. A total of 2988 patients (24.7%) were readmitted within the study period, and 4988 (71.5%) returned within 1 year of the previous encounter. In context of all emergency department admissions from 2013 to 2022, 13.1% had a urine drug screen + for methamphetamine. CONCLUSIONS: Hospitalizations with recent methamphetamine use doubled at our institution from 2012 to 2022. In addition, 1 in 4 is readmitted (typically within 1 year), and a minority requires ICU care.

Secondary peritonitis in a patient with cirrhosis involving Hyphopichia burtonii, an emerging fungal pathogen.

We present a case where Hyphopichia burtonii, a yeast, speciated from peritoneal fluid in a cirrhotic patient with secondary peritonitis. The patient, a man in his 60s with decompensated cirrhosis, was admitted for an upper gastrointestinal (GI) bleed. On admission, he was treated empirically for spontaneous bacterial peritonitis (SBP) but failed to improve with antibiotics. Serial paracenteses revealed polymicrobial peritonitis and rising peritoneal polymorphonuclear leukocytes (PMNs). These findings raised concerns for secondary peritonitis, prompting an abdominal computed tomography (CT) scan which revealed ischemic bowel. Among the peritoneal microbiota isolated, Hyphopichia burtonii predominated. Hyphopichia burtonii has only recently been reported as a human pathogen, previously it had only reported as a pathogen in bats[1,2].

Characteristics of Post-ICU and Post-COVID Recovery Clinics in 29 U.S. Health Systems.

The multifaceted long-term impairments resulting from critical illness and COVID-19 require interdisciplinary management approaches in the recovery phase of illness. Operational insights into the structure and process of recovery clinics (RCs) from heterogeneous health systems are needed. This study describes the structure and process characteristics of existing and newly implemented ICU-RCs and COVID-RCs in a subset of large health systems in the United States. DESIGN: Cross-sectional survey. SETTING: Thirty-nine RCs, representing a combined 156 hospitals within 29 health systems participated. PATIENTS: None. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: RC demographics, referral criteria, and operating characteristics were collected, including measures used to assess physical, psychologic, and cognitive recoveries. Thirty-nine RC surveys were completed (94% response rate). ICU-RC teams included physicians, pharmacists, social workers, physical therapists, and advanced practice providers. Funding sources for ICU-RCs included clinical billing (n = 20, 77%), volunteer staff support (n = 15, 58%), institutional staff/space support (n = 13, 46%), and grant or foundation funding (n = 3, 12%). Forty-six percent of RCs report patient visit durations of 1 hour or longer. ICU-RC teams reported use of validated scales to assess psychologic recovery (93%), physical recovery (89%), and cognitive recovery (86%) more often in standard visits compared with COVID-RC teams (psychologic, 54%; physical, 69%; and cognitive, 46%). CONCLUSIONS: Operating structures of RCs vary, though almost all describe modest capacity and reliance on volunteerism and discretionary institutional support. ICU- and COVID-RCs in the United States employ varied funding sources and endorse different assessment measures during visits to guide care coordination. Common features include integration of ICU clinicians, interdisciplinary approach, and focus on severe critical illness. The heterogeneity in RC structures and processes contributes to future research on the optimal structure and process to achieve the best postintensive care syndrome and postacute sequelae of COVID outcomes.

Respiratory Therapists in an ICU Recovery Clinic: Two Institutional Experiences and Review of the Literature.

Post-intensive care syndrome is an increasingly recognized complication of critical illness, with patients reporting new problems in physical, mental health and/or psychosocial, and cognitive function for months to years after their acute illness. As a way of diagnosing and treating post-intensive care syndrome, many centers around the world have established ICU recovery clinics, which take a multidisciplinary approach to care after the ICU. Dyspnea and pulmonary dysfunction are frequently encountered concerns in the post-ICU population. Despite this, few ICU recovery clinics have described how respiratory therapists (RTs) can contribute to treating these symptoms. We reviewed the literature with regard to the roles of an RT in post-ICU follow-up, described our institutional experiences with having RTs as part of our ICU recovery clinics, and identified additional ways that RTs might contribute to a post-intensive care syndrome diagnosis and treatment. Although RTs can provide invaluable experience and contributions to an ICU recovery clinic, there are few articles in the published literature on the ways in which this can be accomplished. We, therefore, provide analogies to other multidisciplinary clinic models as well as our own experiences. Future studies should focus on examining the impact of respiratory therapy diagnostic testing and interventions in the ICU recovery clinic on both patient and provider outcomes.

Assessing Patients for Air Travel.

Advising patients before air travel is a frequently overlooked, but important, role of the physician, particularly primary care providers and pulmonary specialists. Although physiologic changes occur in all individuals during air travel, those with underlying pulmonary disease are at increased risk of serious complications and require a specific approach to risk stratification. We discuss the available tools for assessment of preflight risk and strategies to minimize potential harm. We also present a case discussion to illustrate our approach to assessing patients for air travel and discuss the specific conditions that should prompt a more thorough preflight workup.

E-cigarette, or vaping, product use-associated lung injury (EVALI) treated with veno-venous extracorporeal membrane oxygenation (VV-ECMO) and ultra-protective ventilator settings.

A 19-year-old man vaping with tetrahydrocannabinol presented with dyspnoea and right pneumothorax. History, imaging and negative infectious workup were consistent with E-cigarette, or vaping, product use-associated lung injury (EVALI). Treated with systemic steroids, he developed acute respiratory distress syndrome and was intubated requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO) by hospital day 3. Using VV-ECMO, very-low tidal volume ventilation of 1.5 cc/kg was achieved, as was daily ambulation. VV-ECMO was decannulated on hospital day 9 and the patient was extubated the next day. He was discharged home on hospital day 13 without oxygen. At post-intensive care unit clinic follow-up, he had lost 20 kg of weight while hospitalised and reported nightmares. Patients with EVALI may be supported with VV-ECMO, which allows ultra-lung-protective mechanical ventilation that may minimise ventilator-induced lung injury. Follow-up in patients with EVALI is essential to diagnose and treat comorbidities, follow lung function and prevent relapses.

Noninvasive measurement of pulmonary gas exchange: comparison with data from arterial blood gases.

A new noninvasive method was used to measure the impairment of pulmonary gas exchange in 34 patients with lung disease, and the results were compared with the traditional ideal alveolar-arterial Po2 difference (AaDO2) calculated from arterial blood gases. The end-tidal Po2 was measured from the expired gas during steady-state breathing, the arterial Po2 was derived from a pulse oximeter if the SpO2 was 95% or less, which was the case for 23 patients. The difference between the end-tidal and the calculated Po2 was defined as the oxygen deficit. Oxygen deficit was 42.7 mmHg (SE 4.0) in this group of patients, much higher than the means previously found in 20 young normal subjects measured under hypoxic conditions (2.0 mmHg, SE 0.8) and 11 older normal subjects (7.5 mmHg, SE 1.6) and emphasizes the sensitivity of the new method for detecting the presence of abnormal gas exchange. The oxygen deficit was correlated with AaDO2 ( R2 0.72). The arterial Po2 that was calculated from the noninvasive technique was correlated with the results from the arterial blood gases ( R2 0.76) and with a mean bias of +2.7 mmHg. The Pco2 was correlated with the results from the arterial blood gases (R2 0.67) with a mean bias of -3.6 mmHg. We conclude that the oxygen deficit as obtained from the noninvasive method is a very sensitive indicator of impaired pulmonary gas exchange. It has the advantage that it can be obtained within a few minutes by having the patient simply breathe through a tube.
