The perioperative handoff protocol: evaluating impacts on handoff defects and provider satisfaction in adult perianesthesia care units.

STUDY OBJECTIVE: To evaluate a new perioperative handoff protocol in the adult perianesthesia care units (PACUs). DESIGN: Prospective, unblinded cross-sectional study. SETTING: Perianesthesia care unit in a tertiary care facility serving 55,000 patients annually. PATIENTS: One hundred three surgery patients. INTERVENTIONS: During a 4-week preintervention phase, 53 perioperative handoffs were observed, and data were collected daily by a trained observer. Educational sessions were conducted to train perioperative practitioners on the new protocol. Two weeks after implementation, 50 consecutive handoffs were observed, and practitioners were surveyed with the same methodology as in the preintervention phase. MEASUREMENTS: Type of information shared, type and duration of procedure, total duration of handoff, number and type of providers at the bedside, number of report interruptions, environmental distractions, and any other disruptive events. Observers also tracked technical/equipment problems to include malfunctioning or compromised operation of medical equipment, such as the cardiac monitor, transducer, oxygen tank, and pulse oximeter. MAIN RESULTS: A total of 103 handoffs were observed (53 preintervention and 50 postintervention). The mean number of defects per handoff decreased from 9.92 to 3.68 (P < .01). The mean number of missed information items from the surgery report decreased from 7.57 to 1.2 items per handoff and from 2.02 to 0.94 (P < .01) for the anesthesia report. Technical defects reported by unit nurses decreased from 0.34 to 0.10 (P = .04). Verbal reports delivered by surgeons increased from 21.2% to 83.3%. Although the mean duration of handoffs increased by 2 minutes (P = .01), the average time from patient arrival at PACU to handoff start was reduced by 1.5 minutes (P = .01). Satisfaction with the handoff improved significantly among PACU nurses. CONCLUSIONS: The perioperative handoff protocol implementation was associated with improved information sharing and reduced handoff defects.

Dexmedetomidine preserves attention/calculation when used for cooperative and short-term intensive care unit sedation.

PURPOSE: Differential effects on cognition were recently demonstrated between dexmedetomidine (DEX) and propofol (PRO) when used for cooperative sedation. Propofol was found to reduce cognition, whereas DEX improved cognition. To further discriminate these effects, we evaluated the effect of PRO vs DEX in selected areas of cognition. METHODS: This is a post hoc analysis of the Acute Neurologic Intensive Care Unit Sedation Trial and an investigator-initiated, prospective, randomized, double-blinded, crossover study, comparing the effect of PRO and DEX on cognition measure by the Johns Hopkins Adapted Cognitive Exam (ACE). A linear model analysis accounting for within-patient correlation of measures was used to estimate differences in ACE subscales between drugs. RESULTS: Propofol diminished adjusted scores on all ACE subscales (P < .05), whereas DEX improved adjusted scores selectively for attention/calculation (3.55; 95% confidence interval, 1.49-5.61; P < .01). The positive and significant difference in ACE scores between agents was present across subscales. CONCLUSIONS: Our findings indicate that DEX improved ACE attention/calculation subscale in awake patients receiving cooperative sedation. This is in contrast to the deterioration in all mean ACE subscale scores observed using PRO, suggesting DEX preserved cognitive function with specific preservation of focus and attention and allows for greater cognition compared with PRO across all cognitive domains.

Falling temperature and colder weather are associated with an increased risk of aneurysmal subarachnoid hemorrhage.

OBJECTIVE: To use weather data to predict increased incidence of aneurysmal subarachnoid hemorrhage (aSAH) at a large institution with an extensive referral network in response to falling temperatures. METHODS: In a retrospective study, 1175 prospectively collected aSAH cases accrued over 18 years from one hospital were reviewed to determine if season, maximum ambient temperature (MAT), average relative humidity, and atmospheric pressure were related to incidence of aSAH at that institution on a given day. A Poisson regression model was used to assess daily risk of incident aSAH based on daily MAT and 1-day change in MAT. RESULTS: A MAT decrease of 1°F from one day to the next was associated with a 0.6% increase in risk of aSAH (relative risk [RR]=1.006, P=0.016). The increased risk associated with MAT decrease from the previous day was especially strong for female patients (RR=1.008/°F, P=0.007) and drove the overall model, representing 72% of cases. In addition, warmer temperatures were associated with a decreased risk of aSAH; each 1°F increase in temperature compared with the previous day was associated with a 0.3% decrease in risk of aSAH (RR=0.997; P<0.001). CONCLUSIONS: A 1-day decrease in temperature and colder daily temperatures were associated with an increased risk of incident aSAH at a single institution with a large referral network. These variables appeared to act synergistically and independently of season. These relationships were particularly predominant in the fall when the transition from warmer to colder temperatures occurred.

Perceived benefit of a telemedicine consultative service in a highly staffed intensive care unit.

PURPOSE: The aim of this study was to evaluate whether a nocturnal telemedicine service improves culture, staff satisfaction, and perceptions of quality of care in a highly staffed university critical care system. METHODS: We conducted an experiment to determine the effect of telemedicine on nursing-staff satisfaction and perceptions of the quality of care in an intensive care unit (ICU). We surveyed ICU nurses using a modified version of a previously validated tool before deployment and after a 2-month experimental program of tele-ICU. Nurses in another, similar ICU within the same hospital academic medical center served as concurrent controls for the survey responses. RESULTS: Survey responses were measured using a 5-point Likert scale, and results were analyzed using paired t testing. Survey responses of the nurses in the intervention ICU (n = 27) improved significantly after implementation of the tele-ICU program in the relations and communication subscale (2.99 ± 1.13 pre vs 3.27 ± 1.27 post, P < .01), the psychological working conditions and burnout subscale (3.10 ± 1.10 pre vs 3.23 ± 1.11 post, P < .02), and the education subscale (3.52 ± 0.84 pre vs 3.76 ± 0.78 post, P < .03). In contrast, responses in the control ICU (n = 11) declined in the patient care and perceived effectiveness (3.94 ± 0.80 pre vs 3.48 ± 0.86 post, P < .01) and the education (3.95 ± 0.39 pre vs 3.50 ± 0.80 post, P < .05) subscales. CONCLUSION: Telemedicine has the potential to improve staff satisfaction and communication in highly staffed ICUs.

Validity and reliability of The Johns Hopkins Adapted Cognitive Exam for critically ill patients.

OBJECTIVE: To validate The Johns Hopkins Adapted Cognitive Exam designed to assess and quantify cognition in critically ill patients. DESIGN: Prospective cohort study. SETTING: Neurosciences, surgical, and medical intensive care units at The Johns Hopkins Hospital. PATIENTS: One hundred six adult critically ill patients. INTERVENTIONS: One expert neurologic assessment and four measurements of the Adapted Cognitive Exam (all patients). Four measurements of the Folstein Mini-Mental State Examination in nonintubated patients only. Adapted Cognitive Exam and Mini-Mental State Examination were performed by 76 different raters. MEASUREMENTS AND MAIN RESULTS: One hundred six patients were assessed, 46 intubated and 60 nonintubated, resulting in 424 Adapted Cognitive Exam and 240 Mini-Mental State Examination measurements. Criterion validity was assessed by comparing Adapted Cognitive Exam with a neurointensivist's assessment of cognitive status (ρ = 0.83, p < .001). Ordinal logistic regression established optimal predicted cut points for cognitive status classification (≤ 28 = severely impaired, 29-55 = moderately impaired, ≥ 56 = mildly impaired or normal). Using these cut points, the Adapted Cognitive Exam appropriately classified cognitive status 90% of the time. Construct validity was assessed by comparing Adapted Cognitive Exam with Mini-Mental State Examination in nonintubated patients (ρ = 0.81, p < .001). Face validity was assessed by surveying raters who used both the Adapted Cognitive Exam and Mini-Mental State Examination and indicated the Adapted Cognitive Exam was an accurate reflection of the patient's cognitive status, more sensitive a marker of cognition than the Mini-Mental State Examination, and easy to use. The Adapted Cognitive Exam demonstrated excellent interrater reliability (intraclass correlation coefficient = 0.997; 95% confidence interval 0.997-0.998) and interitem reliability of each of the five subscales of the Adapted Cognitive Exam and Mini-Mental State Examination (Cronbach's α: range for Adapted Cognitive Exam = 0.83-0.88; range for Mini-Mental State Examination = 0.72-0.81). CONCLUSION: The Adapted Cognitive Exam is the first valid and reliable examination for the assessment and quantification of cognition in critically ill patients. It provides a useful, objective tool that can be used by any member of the interdisciplinary critical care team to support clinical assessment and research efforts.
