As the coronavirus disease 2019 (COVID-19) pandemic spread around the world, the US Surgeon General called for the cancellation of elective surgeries. At a large academic medical center in the Northeast, there was a resulting surplus of perioperative nurses who were deployed to inpatient units in need of skilled nursing care for a surge of COVID-19 patients. To prepare them for deployment to inpatient units, perioperative leaders developed a core curriculum to ensure that the OR nurses possessed the skills and knowledge required to successfully care for patients outside the OR with the same level of care and compassion that they provided to perioperative patients.

Hazardous drug (HD) use in the perioperative environment poses unique challenges and risks for exposure that can have adverse consequences for perioperative personnel. The United States Pharmacopeial Convention has implemented new standards to address the safe handling and administration of HDs by health care workers. To comply with these standards and minimize perioperative personnel's occupational exposure to HDs, a multidisciplinary team at an academic medical center in Boston that was performing an increased number and variety of operative and other invasive procedures using antineoplastic agents updated their protocol for the safe use of HDs in the OR.

Personal communication devices (PCDs) support reliable information sharing between clinical personnel to ease workflow processes. Perioperative leaders at a major medical center conducted a long-term quality improvement project evaluating perioperative nurse perceptions regarding PCDs. Perioperative nurses completed two surveys and the investigators conducted an independent group t test (2-tailed) to test for differences in RN perceptions of PCDs from initial use during a pilot study and after the nurses had used the technology for four years.

Objectives: The United States National Institute for Occupational Safety and Health (NIOSH) is developing a protocol to assess the containment performance of closed system transfer devices (CSTDs) when used for drug preparation (task 1) and administration (task 2) and published a draft protocol in September 2016. Nine possible surrogates were proposed by NIOSH for use in the testing. The objectives of this study were to: (A) select the most appropriate surrogate; (B) validate the NIOSH protocol using this surrogate; and (C) determine the containment performance of four commercial CSTDs as compared with an open system of needle and syringe using the validated NIOSH protocol.

Patients with cardiac morbidities admitted for cardiac surgical procedures require perioperative nurses with a high level of complex nursing skills. Orienting new cardiac team members takes commitment and perseverance in light of variable staffing levels, high-acuity patient populations, an active cardiac surgical schedule, and the unpredictability of scheduling patients undergoing cardiac transplantation. At an academic medical center in Boston, these issues presented opportunities to orient new staff members to the scrub person role, but hampered efforts to provide active learning opportunities in a safe environment.

Stable ultrashort light pulses and frequency combs generated by mode-locked lasers have many important applications including high-resolution spectroscopy, fast chemical detection and identification, studies of ultrafast processes, and laser metrology. While compact mode-locked lasers emitting in the visible and near infrared range have revolutionized photonic technologies, the systems operating in the mid-infrared range where most gases have their strong absorption lines, are bulky and expensive and rely on nonlinear frequency down-conversion. Quantum cascade lasers are the most powerful and versatile compact light sources in the mid-infrared range, yet achieving their mode-locked operation remains a challenge, despite dedicated effort.
