Reducing Physical Restraint Use in the Medical Behavioral Unit.

OBJECTIVES: Children with behavioral health conditions often experience agitation when admitted to children's hospitals. Physical restraint should be used only as a last resort for patient agitation because it endangers the physical and psychological safety of patients and employees. At the medical behavioral unit (MBU) in our children's hospital, we aimed to decrease the weekly rate of physical restraint events per 100 MBU patient-days, independent of patient race, ethnicity, or language, from a baseline mean of 14.0 to <10 within 12 months. METHODS: Using quality improvement methodology, a multidisciplinary team designed, tested, and implemented interventions including a series of daily deescalation huddles led by a charge behavioral health clinician that facilitated individualized planning for MBU patients with the highest behavioral acuity. We tracked the weekly number of physical restraint events per 100 MBU patient-days as a primary outcome measure, weekly physical restraint event duration as a secondary outcome measure, and MBU employee injuries as a balancing measure. RESULTS: Our cohort included 527 consecutive patients hospitalized in the MBU between January 2021 and January 2023. Our 2021 baseline mean of 14.0 weekly physical restraint events per 100 MBU patient-days decreased to 10.0 during our 2022 intervention period from January through July and 4.1 in August, which was sustained through December. Weekly physical restraint event duration also decreased from 112 to 67 minutes without a change in employee injuries. CONCLUSIONS: Multidisciplinary huddles that facilitated daily deescalation planning safely reduced the frequency and duration of physical restraint events in the MBU.

Characteristics, disposition, and outcomes of children hospitalized for mental health boarding at a children's hospital.

Increasingly, youth experiencing mental health crises present to acute care medical hospitals and "board" on medical units due to inpatient psychiatric bed shortages. We conducted a retrospective cohort study of children experiencing mental health boarding at a US children's hospital from October 2020 to September 2022. We examined associations between patients' characteristics and their disposition and outcomes. Our cohort included 1891 boarding hospitalizations: 53.9% transferred to an inpatient psychiatric hospital and 46.1% discharged home. Characteristics associated with not being transferred to an inpatient psychiatric hospital included age <13 years (adjusted odds ratio [aOR] 0.6; 95% confidence interval [CI]: 0.4-0.7), disruptive or aggressive behavior (aOR 0.6; 95% CI: 0.4-0.8), psychosis (aOR 0.5; 95% CI: 0.3-0.8), COVID-19 infection (aOR 0.3; 95% CI: 0.2-0.6), or a complex chronic medical condition (aOR 0.8; 95% CI: 0.6-1.0). Our findings suggest that certain populations of children experiencing mental health boarding face disparate access to inpatient psychiatric care.

Daytime Atmospheric Halogen Cycling through Aqueous-Phase Oxygen Atom Chemistry.

Halogen atoms are important atmospheric oxidants that have unidentified daytime sources from photochemical halide oxidation in sea salt aerosols. Here, we show that the photolysis of nitrate in aqueous chloride solutions generates nitryl chloride (ClNO2) in addition to Cl2 and HOCl. Experimental and modeling evidence suggests that O(3P) formed in the minor photolysis channel from nitrate oxidizes chloride to Cl2 and HOCl, which reacts with nitrite to form ClNO2. This chemistry is different than currently accepted mechanisms involving chloride oxidation by OH and could shift our understanding of daytime halogen cycling in the lower atmosphere.

Factors influencing agitation, de-escalation, and physical restraint at a children's hospital.

BACKGROUND: Children hospitalized in medical hospitals are at risk of agitation. Physical restraint may be used to maintain patient and staff safety during de-escalation, but physical restraint use is associated with physical and psychological adverse events. OBJECTIVE: We sought to better understand which work system factors help clinicians prevent patient agitation, improve de-escalation, and avoid physical restraint. DESIGN, SETTING, AND PARTICIPANTS: We used directed content analysis to extend the Systems Engineering Initiative for Patient Safety model to clinicians working with children at risk for agitation at a freestanding children's hospital. INTERVENTION, MAIN OUTCOME, AND MEASURES: We conducted semistructured interviews to examine how five clinician work system factors affected patient agitation, de-escalation, and restraint: person, environment, tasks, technology and tools, and organization. Interviews were recorded, transcribed, and analyzed until saturation. RESULTS: Forty clinicians participated in this study, including 21 nurses, 15 psychiatric technicians, 2 pediatric physicians, 1 psychologist, and 1 behavior analyst. Work system factors that contributed to patient agitation were medical tasks like vital signs and the hospital environment including bright lights and neighboring patients' noises. Supports that helped clinicians de-escalate patients included adequate staffing and accessible toys and activities. Participants indicated that organizational factors were integral to team de-escalation, drawing connections between units' teamwork and communication cultures and their likelihood of successful de-escalation without the use of physical restraint. CONCLUSION: Clinicians perceived that medical tasks, hospital environmental factors, clinician attributes, and team communication influenced patients' agitation, de-escalation, and physical restraint. These work system factors provide opportunities for future multi-disciplinary interventions to reduce physical restraint use.

Factors Associated With Inpatient Subspecialty Consultation Patterns Among Pediatric Hospitalists.

Importance: Subspecialty consultation is a frequent, consequential practice in the pediatric inpatient setting. Little is known about factors affecting consultation practices. Objectives: To identify patient, physician, admission, and systems characteristics that are independently associated with subspecialty consultation among pediatric hospitalists at the patient-day level and to describe variation in consultation utilization among pediatric hospitalist physicians. Design, Setting, and Participants: This retrospective cohort study of hospitalized children used electronic health record data from October 1, 2015, through December 31, 2020, combined with a cross-sectional physician survey completed between March 3 and April 11, 2021. The study was conducted at a freestanding quaternary children's hospital. Physician survey participants were active pediatric hospitalists. The patient cohort included children hospitalized with 1 of 15 common conditions, excluding patients with complex chronic conditions, intensive care unit stay, or 30-day readmission for the same condition. Data were analyzed from June 2021 to January 2023. Exposures: Patient (sex, age, race and ethnicity), admission (condition, insurance, year), physician (experience, anxiety due to uncertainty, gender), and systems (hospitalization day, day of week, inpatient team, and prior consultation) characteristics. Main Outcomes and Measures: The primary outcome was receipt of inpatient consultation on each patient-day. Risk-adjusted consultation rates, expressed as number of patient-days consulting per 100, were compared between physicians. Results: We evaluated 15 922 patient-days attributed to 92 surveyed physicians (68 [74%] women; 74 [80%] with ≥3 years' attending experience) caring for 7283 unique patients (3955 [54%] male patients; 3450 [47%] non-Hispanic Black and 2174 [30%] non-Hispanic White patients; median [IQR] age, 2.5 ([0.9-6.5] years). Odds of consultation were higher among patients with private insurance compared with those with Medicaid (adjusted odds ratio [aOR], 1.19 [95% CI, 1.01-1.42]; P = .04) and physicians with 0 to 2 years of experience vs those with 3 to 10 years of experience (aOR, 1.42 [95% CI, 1.08-1.88]; P = .01). Hospitalist anxiety due to uncertainty was not associated with consultation. Among patient-days with at least 1 consultation, non-Hispanic White race and ethnicity was associated with higher odds of multiple consultations vs non-Hispanic Black race and ethnicity (aOR, 2.23 [95% CI, 1.20-4.13]; P = .01). Risk-adjusted physician consultation rates were 2.1 times higher in the top quartile of consultation use (mean [SD], 9.8 [2.0] patient-days consulting per 100) compared with the bottom quartile (mean [SD], 4.7 [0.8] patient-days consulting per 100; P < .001). Conclusions and Relevance: In this cohort study, consultation use varied widely and was associated with patient, physician, and systems factors. These findings offer specific targets for improving value and equity in pediatric inpatient consultation.

HONO Measurement by Catalytic Conversion to NO on Nafion Surfaces.

A selective catalytic converter has been developed to quantify nitrous acid (HONO), a photochemical precursor to NO and OH radicals that drives the formation of ozone and other pollutants in the troposphere. The converter is made from a sulfonated tetrafluoroethylene-based fluoropolymer-copolymer (Nafion) that was found to convert HONO to NO with unity yield under specific conditions. When coupled to a commercially available NOx (=NO + NO2) chemiluminescence (CL) analyzer, the system measures HONO with a limit of detection as low as 64 parts-per-trillion (ppt) (1 min average) in addition to NOx. The converter is selective for HONO when tested against other common gas-phase reactive nitrogen species, although loss of O3 on Nafion is a potential interference. The sensitivity and selectivity of this method allow for accurate measurement of atmospherically relevant concentrations of HONO. This was demonstrated by good agreement between HONO measurements made with the Nafion-CL method and those made with chemical ionization mass spectrometry in a simulation chamber and in indoor air. The observed reactivity of HONO on Nafion also has significant implications for the accuracy of CL NOx analyzers that use Nafion to remove water from sampling lines.

Buffer Assists Electrocatalytic Nitrite Reduction by a Cobalt Macrocycle Complex.

This work reports a combined experimental and computational study of the activation of an otherwise catalytically inactive cobalt complex, [Co(TIM)Br2]+, for aqueous nitrite reduction. The presence of phosphate buffer leads to efficient electrocatalysis, with rapid reduction to ammonium occurring close to the thermodynamic potential and with high Faradaic efficiency. At neutral pH, increasing buffer concentrations increase catalytic current while simultaneously decreasing overpotential, although high concentrations have an inhibitory effect. Controlled potential electrolysis and rotating ring-disk electrode experiments indicate that ammonium is directly produced from nitrite by [Co(TIM)Br2]+, along with hydroxylamine. Mechanistic investigations implicate a vital role for the phosphate buffer, specifically as a proton shuttle, although high buffer concentrations inhibit catalysis. These results indicate a role for buffer in the design of electrocatalysts for nitrogen oxide conversion.

Decreasing the Use of Restraints on Children Admitted for Behavioral Health Conditions.

OBJECTIVES: Pediatric behavioral health admissions to children's hospitals for disposition planning are steadily increasing. These children may exhibit violent behaviors, which can escalate to application of physical limb restraints for safety. Using quality improvement methodology, we sought to decrease physical restraint use on children admitted to our children's hospital for behavioral health conditions from a baseline mean of 2.6% of behavioral health patient days to <1%. METHODS: We included all children ≥3 years of age admitted to our hospital medicine service with a primary behavioral health diagnosis from July 1, 2016, to February 1, 2020. A multidisciplinary team, formed in July 2018, tested interventions based on key drivers targeted toward our aim. The primary outcome measure was the percent of behavioral health patient days on which physical restraints were ordered. The balancing measure was the percent of patient days with a staff injury event. Statistical process control charts were used to view and analyze data. RESULTS: Our cohort included 3962 consecutive behavioral health patient encounters, encompassing a total of 9758 patient days. A 2-year baseline revealed physical restraint orders placed on 2.6% of behavioral health patient days, which was decreased to 0.9% after interventions and has been sustained over 19 months without any change in staff injuries. CONCLUSIONS: Team-based quality improvement methodology was associated with a sustained reduction in physical restraint use on children admitted for behavioral health conditions to our children's hospital. These results indicate that physical restraint use can be safely reduced in children's hospitals.

Costs and Reimbursements for Mental Health Hospitalizations at Children's Hospitals.

The financial impact of the rising number of pediatric mental health hospitalizations is unknown. Therefore, this study assessed costs, reimbursements, and net profits or losses for 111,705 mental health and non-mental health medical hospitalizations in children's hospitals with use of the Pediatric Health Information System and Revenue Management Program. Average financial margins were calculated as (reimbursement per day) - (cost per day), and they were lowest for mental health hospitalizations ($136/day), next lowest for suicide attempt ($518/day), and highest for other medical hospitalizations ($611/day). For 10 of 17 hospitals, margin per day for mental health hospitalizations was lower than margin per day for other medical hospitalizations. For these 10 hospitals, the total net loss for inpatient and observation status mental health hospitalizations, compared with other medical hospitalizations, was $27 million (median, $2.2 million per hospital). Financial margins were usually lower for mental health vs non-mental health medical hospitalizations.
