Pediatric Respiratory Therapists Lack a Standard Mental Model for Managing the Patient Who Is Difficult to Ventilate: A Video Review.

BACKGROUND: All health-care providers who care for infants and children should be able to effectively provide ventilation with a bag and a mask. Respiratory therapists (RTs'), as part of rapid response teams, need to quickly identify the need for airway support and use adjunct airway interventions when subjects are difficult to mask ventilate. Before implementation of an educational curriculum for airway management, we assessed whether pediatric RTs' who enter the room of a simulated infant mannequin in severe respiratory distress are able to apply bag-mask ventilation within 60 s and implement 2 adjunct airway maneuvers in a patient who is difficult to ventilate. METHODS: All pediatric RTs' were required to attend one high-fidelity simulation at the Johns Hopkins Medicine Simulation Center. The sessions were reviewed to evaluate whether the therapists would implement adjunct maneuvers to a patient who was in respiratory distress and was difficult to ventilate. RESULTS: Twenty-eight therapists participated in the baseline skills assessment session, and 26 (72% of eligible therapists) were evaluable with video clips. Only 3 of 26 (12%) attempted bag-mask ventilation within 60 s. Although all the therapists attempted one airway maneuver, only 65% were able to implement ≥2 airway maneuvers and achieve effective ventilation, with a wide range of time (98-298 s). There was no pattern regarding which intervention was implemented first, second, and so forth. CONCLUSIONS: Our team of pediatric RTs' did not share a standard mental model for initiating bag-mask ventilation during impending respiratory failure or implementing airway adjuncts. This may place children who are critically ill at risk of suboptimal management and threaten clinical outcomes. Therapist performance indicated that no established care algorithm had been effectively implemented or that skill retention was poor. A change in the content and delivery method of bag-mask ventilation training is warranted to improve the time to performance of key interventions and to establish a clear cognitive framework of difficult mask ventilation management.

Reducing Inpatient Length of Stay Using a Multicollaborative Protocol for Management of Non-Intensive Care Unit Asthmatics.

Maximizing clinical efficiency through the reduction in inpatient length of stay (LOS) using standardized protocols has been a major objective among hospital administrators, most notably in the context of recent healthcare reimbursement changes at statewide levels. The objective of our project was to determine whether a synchronous change in an inpatient asthma protocol that relied on a respiratory therapist (RT)-driven bronchodilator weaning algorithm and bronchodilator therapy given through a metered dose inhaler (MDI) plus valved holding chamber (VHC) could impact clinical and financial outcomes. A pre-post study assessed patients aged 2-21 years of age admitted with a primary diagnosis of status asthmaticus. The effect of the protocol was measured from October 2014 to July 2015. Outcome variables included patient demographics, hospital LOS, all-patient refined diagnosis-related groups (APR-DRGs), and inpatient charges. Outcomes were compared between the preimplementation and postimplementation time periods. Statistical significance was measured using Wilcoxon signed-rank test and bootstrap logistic regression models. Protocol patients (n = 110) had a similar demographic and clinical profile compared with the matched population from the previous nonprotocol fiscal year (n = 150). Use of the protocol resulted in a significantly reduced LOS that maintained significance after adjusting for APR-DRGs weight (P < 0.05). The protocol did not alter the total hospital billing charges. A nonstatistically significant reduction in 30-day readmission rates was observed among those administered the protocol. An RT-led weaning protocol using a quantitative scoring system and MDI+VHC for bronchodilator administration resulted in a significantly reduced LOS.

Attrition with spinal cord stimulation.

The aim of this prospective study was to investigate whether spinal cord stimulation (SCS) significantly reduces pain intensity for up to 18-month follow-up in patients with chronic neuropathic pain. Forty-eight patients were recruited. Patients rated their pain using a Visual analog scale (VAS) and pain-related disability using the Oswestry Disability Index (ODI) at baseline (1 week prior to SCS surgery) and at 6-, 12-, and 18-month follow-up. Pain intensity significantly decreased from baseline to all 3 time points [F (3,135) = 16.264, p < 0.001]. The greatest difference in the reduction of pain intensity was observed between baseline (M = 7.20, SD = 1.34) and 6-month follow-up (M = 4.60, SD = 2.20), [t(47) = 6.741, p < 0.001]. However, when looking at differences between the 6-month follow-up and subsequent assessments, statistically significant increases in pain intensity from the 6-month to the 12-month follow-up [t(47) = -2.788, p = 0.008], and from the 6-month to the 18-month follow-up [t(47) = -3.339, p = 0.002] could be observed. Statistically significant changes were also observed for clinical changes in pain scores [F (2,94) = 4.972, p = 0.009. There was a significant decrease in the percentage of clinical change obtained from the 6-month (M = 33.19, SD = 35.63) to the 12-month follow-up (M = 23.76, SD = 33.62), [t(47) = 2.347, p = 0.025], and from the 6-month to the 18-month follow-up (M = 18.34, SD = 33.51), [t(47) = 3.072, p = 0.004]. A number of patients also reported higher levels of pain intensity at the 12-and 18-month follow-up than at baseline. Pain-related disability scores significantly decreased from baseline (M = 55.04, SD = 16.43) to the 6-month follow up (M = 46.98, SD = 19.05), [t(47) = 3.464, p = 0.001] and from baseline to the 12-month follow up (M = 48.49, SD = 20.94), [t(47) = 2.918, p = 0.005], but not during the 18-month follow up (M = 51.75, SD = 20.92), [t(47) = 1.330, p = .190]. There was a significant increase in pain-related disability between the 6- and the 18-month follow up [t(47) = -2.188. p = 0.034]. These findings suggest that the beneficial effect of SCS on pain intensity may diminish over time, and that the 6-month follow-up scores may reflect a placebo effect.

Analysis of psychological characteristics impacting spinal cord stimulation treatment outcomes: a prospective assessment.

BACKGROUND: Psychological factors are recognised as influencing the outcome of spinal cord stimulation (SCS) although there is currently no consensus as to which factors impact upon SCS efficacy. OBJECTIVE: To identify psychological characteristics that may impact the efficacy of SCS. STUDY DESIGN: Prospective evaluation. SETTING: Single secondary care center in Dudley, United Kingdom. PATIENTS: Seventy-five patients were initially recruited and 56 patients (31 women and 25 men) were followed-up for 12-months. INTERVENTION: SCS for the management of chronic non-cancer pain. MAIN OUTCOME MEASURES: Outcome measures assessed at baseline, 6 months, and 12 months following SCS implantation included the visual analogue scale (VAS), Oswestry disability index (ODI), hospital anxiety and depression (HAD) scale, and the pain coping strategies questionnaire (PCSQ). RESULTS: Statistically significant improvements were observed for the VAS (P < 0.001), ODI (P = 0.011), anxiety (P = 0.042), and depression (P = 0.010) in the HAD scale and for the subscales reinterpreting pain sensation (P = 0.018), control over pain (P = 0.001), and ability to decrease pain (P < 0.001) of the PCSQ. We observed that depression and autonomous coping (control over pain, ability to reduce pain, and catastrophizing) may impact sensory aspects such as pain intensity and disability scores affecting the outcome of SCS treatment. Age at time of implant and duration of pain prior to implant were also found to impact SCS efficacy. LIMITATIONS: It has been reported that loss of analgesia may be experienced within 12 to 24 months following SCS implantation and therefore, it would be of interest to follow patients over a longer period. CONCLUSIONS: This study demonstrates that psychological aspects such as depression and autonomous coping may impact SCS treatment. Addressing these issues prior to SCS implantation may improve SCS long-term outcome.

Assessing reverse 911®: a case study of the 2007 San Diego wildfires.

In October 2007, 250,000 residents of San Diego County were forced to evacuate as wildfires burned 62 miles(2) in 24 hours. In 2005, the Sheriff's Department invested in Reverse 911® to contact residents upon emergencies. The system was used during this wildfire, and by the following midday, had made 394,915 calls. Shortly thereafter, 1,210 residents were surveyed to investigate the effectiveness of this technology. Findings reveal that 42 percent of respondents received their first warning from a Reverse 911® call while an additional 7 percent received the same call, but not as their first warning, as compared to all other methods used.
