RESUMO

Aim: Our aim was to examine how code status orders for patients hospitalized with COVID-19 changed over time as the pandemic progressed and outcomes improved. Methods: This retrospective cohort study was performed at a single academic center in the United States. Adults admitted between March 1, 2020, and December 31, 2021, who tested positive for COVID-19, were included. The study period included four institutional hospitalization surges. Demographic and outcome data were collected and code status orders during admission were trended. Data were analyzed with multivariable analysis to identify predictors of code status. Results: A total of 3615 patients were included with full code (62.7%) being the most common final code status order followed by do-not-attempt-resuscitation (DNAR) (18.1%). Time of admission (per every six months) was an independent predictor of final full compared to DNAR/partial code status (p = 0.04). Limited resuscitation preference (DNAR or partial) decreased from over 20% in the first two surges to 10.8% and 15.6% of patients in the last two surges. Other independent predictors of final code status included body mass index (p < 0.05), Black versus White race (0.64, p = 0.01), time spent in the intensive care unit (4.28, p = <0.001), age (2.11, p = <0.001), and Charlson comorbidity index (1.05, p = <0.001). Conclusions: Over time, adults admitted to the hospital with COVID-19 were less likely to have a DNAR or partial code status order with persistent decrease occurring after March 2021. A trend toward decreased code status documentation as the pandemic progressed was observed.

RESUMO

Aim: Our aim is to characterize code status documentation for patients hospitalized with novel coronavirus 2019 (COVID-19) during the first peak of the pandemic, when prognosis, resource availability, and provider safety were uncertain. Methods: This retrospective cohort study was performed at a single tertiary academic medical center. Adult patients admitted between March 1, 2020 and October 31, 2020 who tested positive for COVID-19 were included. Demographic and hospital outcome data were collected. Code status orders during this admission and prior admissions were trended. Data were analyzed with multivariable analysis to identify predictors of code status choice. Results: A total of 720 patients were included. The majority (70%) were full code and 12% were in do-not-attempt resuscitation (DNAR) status on admission; by discharge, 20% were DNAR. Age (p < 0.001), time in the intensive care unit (ICU) (p < 0.001), and having Medicaid (p = 0.04) compared to private insurance were predictors of DNAR. Fourteen percent had no code status order. Older age (p < 0.001), time in the ICU (p = 0.01), and admission to a teaching service (p < 0.001) were associated with having an order. Of patients with a prior admission (n = 227), 33.5% previously had no code status order and 44.5% had a different code status for their COVID-19 admission. Of those with a change, most transitioned to less aggressive resuscitation preferences. Conclusions: Most patients hospitalized with COVID-19 in our study elected to be full code. Almost half of patients with prepandemic admissions had a different code status during their COVID-19 admission, with a trend toward less aggressive resuscitation preference.

RESUMO

BACKGROUND: Misclassification of wounds in the operating room (OR) can adversely affect surgical site infection (SSI) reporting and reimbursement. This study aimed to measure the effects of a curriculum on documentation of surgical wound classification (SWC) for operating room staff and surgeons. METHODS: Accuracy of SWC was determined by comparing SWC documented by OR staff during the original operation to SWC determined by in-depth chart review. Patients 18 years or older undergoing inpatient surgical procedures were included. Two plan-do-act-study (PDSA) cycles were implemented over the course of 9 months. A total of 747 charts were reviewed. Accuracy of SWC documentation was retrospectively assessed across 248 randomly selected surgeries during a 5-week period prior to interventions and compared to 244 cases and 255 cases of post-intervention data from PDSA1 and PDSA2, respectively. Changes in SWC accuracy were assessed pre- and post-intervention using the kappa coefficient. A p-value for change in agreement was computed by comparing pre- and post-intervention kappa. RESULTS: Inaccurate documentation of surgical wound class decreased significantly following curriculum implementation (kappa improved from 0.553 to 0.739 and 0.757; p = 0.001). Classification accuracy improved across all wound classes; however, class III and IV wounds were more frequently misclassified than class I and II wounds, both before and after the intervention. CONCLUSION: Implementation of a multidisciplinary documentation curriculum resulted in a significant decrease in SWC documentation error. Improved accuracy of SWC reporting may facilitate a better assessment of SSI risk in a complex patient population.

RESUMO

BACKGROUND: Pica is common in pregnancy and is often felt to be benign. The following case of severe pica presenting without anemia is unusual in its presentation, laboratory findings, and treatment. CASE: A 31-year-old multiparous woman at 37 0/7 weeks of gestation presented with esophagitis and gastritis secondary to laundry detergent consumption. She had borderline anemia (hemoglobin of 11 g/dL and hematocrit of 37%, mean corpuscular volume 80%) but was severely iron-deficient (serum ferritin 7 micrograms/dL). Parenteral iron infusion was associated with dramatic resolution of her cravings within 36 hours of treatment. CONCLUSION: Pica may be related to deficient iron stores in the absence of anemia and can result in serious morbidity. Parenteral iron may be associated with rapid pica resolution in symptomatic pregnant patients.

RESUMO

Mesoporous silica nanoparticle-supported lipid bilayers, or "protocells", exhibit a high loading capacity, enhanced colloidal stability, and peptide-directed, cell-specific uptake, making them especially well-suited for targeted delivery of protein toxins to cancer. Protocells loaded with ricin toxin A-chain (RTA) and targeted to hepatocellular carcinoma cause complete cell death at 30 pM of RTA without affecting the viability of control hepatocytes.

RESUMO

The therapeutic potential of small interfering RNAs (siRNAs) is severely limited by the availability of delivery platforms that protect siRNA from degradation, deliver it to the target cell with high specificity and efficiency, and promote its endosomal escape and cytosolic dispersion. Here we report that mesoporous silica nanoparticle-supported lipid bilayers (or "protocells") exhibit multiple properties that overcome many of the limitations of existing delivery platforms. Protocells have a 10- to 100-fold greater capacity for siRNA than corresponding lipid nanoparticles and are markedly more stable when incubated under physiological conditions. Protocells loaded with a cocktail of siRNAs bind to cells in a manner dependent on the presence of an appropriate targeting peptide and, through an endocytic pathway followed by endosomal disruption, promote delivery of the silencing nucleotides to the cytoplasm. The expression of each of the genes targeted by the siRNAs was shown to be repressed at the protein level, resulting in a potent induction of growth arrest and apoptosis. Incubation of control cells that lack expression of the antigen recognized by the targeting peptide with siRNA-loaded protocells induced neither repression of protein expression nor apoptosis, indicating the precise specificity of cytotoxic activity. In terms of loading capacity, targeting capabilities, and potency of action, protocells provide unique attributes as a delivery platform for therapeutic oligonucleotides.
