Quality Improvement Initiative to Increase the Use of Nasogastric Hydration in Infants With Bronchiolitis.

BACKGROUND AND OBJECTIVES: Intravenous (IV) hydration is used primarily in children with bronchiolitis at our institution. Because nasogastric (NG) hydration can provide better nutrition, the goal of our quality improvement (QI) initiative was to increase the rate of NG hydration in eligible children 1 to 23 months old with bronchiolitis by 20% over 6 months. METHODS: We used Plan-Do-Study-Act cycles to increase the use of NG hydration in eligible children. Interventions included educational and system-based changes and sharing parental feedback with providers. Chart reviews were performed to identify the rates of NG hydration, which were plotted over time in a statistical process control p chart. The balancing measure was the rate of complications in children with NG versus IV hydration. RESULTS: Two hundred and ninety-three children who were hospitalized with bronchiolitis needed supplemental hydration during the QI initiative (January 2016-April 2016). Ninety-one children were candidates for NG hydration, and 53 (58%) received NG hydration. The rates of NG hydration increased from a baseline of 0% pre-QI bronchiolitis season (January 2015-April 2015) to 58% during the initiative. There was no aspiration and no accidental placement of the NG tube into a child's airway. Nine patients (17%) in the NG group had a progression of disease requiring nil per os status, and 6 of these were transferred to the PICU whereas none of those in the IV group were transferred to the PICU. Post-QI initiative, the majority of nurses (63%) and physicians (95%) stated that they are more likely to consider NG hydration in children with bronchiolitis. CONCLUSIONS: We successfully increased the rates of NG hydration in eligible children with bronchiolitis by using educational and system-based interventions.

Adolescents' views on barriers to health care: a pilot study.

OBJECTIVES: To determine from adolescents using health care their: 1) perceptions of barriers to obtaining health services, 2) views on how to overcome the barriers and 3) views on how to create an adolescent-friendly primary care practice. DESIGN: Six focus group interviews. METHODS: Adolescents 11-21 years old from three health centers in the Bronx were recruited. MAIN OUTCOME MEASURES: 1) barriers to accessing health care such as insurance, language barriers, transportation, making an appointment; 2) identifying barriers related to issues of consent and confidentiality; 3) exploring barriers to accessing mental health and related issues; and 4) their visions of an adolescent-friendly office. RESULTS: Thirty-one adolescents, aged 11-21 years old, participated. The majority were Hispanic and 52% were female. Fifty percent of adolescents had a routine visit within the past month. Most adolescents reported experiencing barriers to making an appointment. Additionally, they complained about long waiting times to be seen by providers on the day of their scheduled appointment. Another key barrier was related to knowledge and perceptions about consent and confidentiality. Further, in regard to mental health, many adolescents from focus groups reported that they felt that their primary providers had little interest in this topic and limited knowledge about it. Most of the adolescents reported no barriers with insurance, language or transportation. Their visions of an adolescent-friendly office would include a separate adolescent waiting area equipped with entertainment units. CONCLUSION: In this study of adolescents who already have primary care providers and are seemingly well-connected to the health care system, there remained significant reported barriers to accessing necessary health services.

Channel opening by anesthetics and GABA induces similar changes in the GABAA receptor M2 segment.

For many general anesthetics, their molecular basis of action involves interactions with GABA(A) receptors. Anesthetics produce concentration-dependent effects on GABA(A) receptors. Low concentrations potentiate submaximal GABA-induced currents. Higher concentrations directly activate the receptors. Functional effects of anesthetics have been characterized, but little is known about the conformational changes they induce. We probed anesthetic-induced conformational changes in the M2 membrane-spanning, channel-lining segment using disulfide trapping between engineered cysteines. Previously, we showed that oxidation by copper phenanthroline in the presence of GABA of the M2 6' cysteine mutants, alpha(1)T261Cbeta(1)T256C and alpha(1)beta(1)T256C resulted in formation of an intersubunit disulfide bond between the adjacent beta-subunits that significantly increased the channels' spontaneous open probability. Oxidation in GABA's absence had no effect. We examined the effect on alpha(1)T261Cbeta(1)T256C and on alpha(1)beta(1)T256C of oxidation by copper phenanthroline in the presence of potentiating and directly activating concentrations of the general anesthetics propofol, pentobarbital, and isoflurane. Oxidation in the presence of potentiating concentration of anesthetics had little effect. Oxidation in the presence of directly activating anesthetic concentrations significantly increased the channels' spontaneous open probability. We infer that activation by anesthetics and GABA induces a similar conformational change at the M2 segment 6' position that is related to channel opening.
