RESUMO
BACKGROUND: Overutilization of operating theaters (OTs) occurs when actual surgery duration exceeds scheduled duration, which could potentially result in delays or cancelations in subsequent surgeries. We investigate the association between the timing of elective surgery scheduling and OT overutilization. METHODS: A cross-sectional retrospective study was conducted using electronic health record data of 27,423 elective surgeries from July 1, 2016, to July 31, 2018, at a mid-Atlantic academic medical center with 56 OTs. The scheduling precision of each surgery is measured using the ratio of the actual (A) over the scheduled or forecast (F) length of surgery to derive the predictor variable of A/F (actual-to-forecast ratio [AF]). Student t test and χ2 tests analyzed differences between OTs reserved within and over 7 days of surgery for continuous and dichotomous variables, respectively. Hierarchical regression models, controlling for potential confounds from the hospital environment, clinicians' work experience and workloads, patient factors, scheduled OT length, and operational and team factors isolated the association between OTs reserved within 7 days of the elective surgery with AF. RESULTS: The Student t test indicates that OTs reserved within 7 days of surgery had significantly higher AF (1.13 ± 0.53 vs 1.08 ± 0.41; P < .001). In-depth Student t test analyses for 4 patient groups, namely, outpatient, extended recovery, admission after surgery, and inpatient, indicate that AF was only significantly different for OTs reserved within 7 days for the admission after surgery group (1.15 ± 0.47 vs 1.09 ± 0.35; P < .001) but did not reach statistical significance among the outpatient, extended recovery, and inpatient groups. After controlling for potential confounds, hierarchical regression for the admission after surgery group reveals that OTs reserved within 7 days took 2.7% longer than the scheduled length of surgery (AFbeta, 0.027; 95% CI, 0.003-0.051; P = .027). CONCLUSIONS: Elective surgeries scheduled within 7 days of surgery were associated with significantly higher likelihood of OT overutilization for surgical patients who will be admitted after surgery. Further studies at other hospitals and a longer period of time are needed to ascertain a potential "squeeze-in" effect.

BACKGROUND: Medical school academic achievements do not necessarily predict house staff job performance. This study explores a selection mechanism that improves house staff-program fit that enhances the Accreditation Council for Graduate Medical Education Milestones performance ratings. OBJECTIVE: Traditionally, house staff were selected primarily on medical school academic performance. To improve residency performance outcomes, the Program designed a theory-driven selection tool to assess house staff candidates on their personal values and goals fit with Program values and goals. It was hypothesized cohort performance ratings will improve because of the intervention. METHODS: Prospective quasi-experimental cohort design with data from two house staff cohorts at a university-based categorical Internal Medicine Residency Program. The intervention cohort, comprising 45 house staff from 2016 to 2017, was selected using a Behaviorally Anchored Rating Scales (BARS) tool for program fit. The control cohort, comprising 44 house staff from the prior year, was selected using medical school academic achievement scores. House staff performance was evaluated using ACGME Milestones indicators. The mean scores for each category were compared between the intervention and control cohorts using Student's t-tests with Bonferroni correction and Cohen's d for effect size. RESULTS: The cohorts were no different in academic performance scores at time of Program entry. The intervention cohort outperformed the control cohort on all 6 dimensions of Milestones by end-PGY1 and 3 of 6 dimensions by mid-PGY3. CONCLUSION: Selecting house staff based on compatibility with Residency Program values and objectives may yield higher job performance because trainees benefit more from a better fit with the training program.

BACKGROUND: Obtaining vascular access can be challenging during resuscitation following cardiac arrest, and it is particularly difficult and time-consuming in paediatric patients. We aimed to compare the efficacy of high-dose intramuscular (IM) versus intravascular (IV) epinephrine administration with regard to the return of spontaneous circulation (ROSC) in an asphyxia-induced cardiac arrest rat model. METHODS: Forty-five male Sprague-Dawley rats were used for these experiments. Cardiac arrest was induced by asphyxia, and defined as a decline in mean arterial pressure (MAP) to 20 mmHg. After asphyxia-induced cardiac arrest, the rats were randomly allocated into one of 3 groups (control saline group, IV epinephrine group, and IM epinephrine group). After 540 s of cardiac arrest, cardiopulmonary resuscitation was performed, and IV saline (0.01 cc/kg), IV (0.01 mg/kg, 1:100,000) epinephrine or IM (0.05 mg/kg, 1:100,000) epinephrine was administered. ROSC was defined as the achievement of an MAP above 40 mmHg for more than 1 minute. Rates of ROSC, haemodynamics, and arterial blood gas analysis were serially observed. RESULTS: The ROSC rate (61.5%) of the IM epinephrine group was less than that in the IV epinephrine group (100%) but was higher than that of the control saline group (15.4%) (log-rank test). There were no differences in MAP between the two groups, but HR in the IM epinephrine group (beta coefficient = 1.02) decreased to a lesser extent than that in the IV epinephrine group with time. CONCLUSIONS: IM epinephrine induced better ROSC rates compared to the control saline group in asphyxia-induced cardiac arrest, but not compared to IV epinephrine. The IM route of epinephrine administration may be a promising option in an asphyxia-induced cardiac arrest.

BACKGROUND: Past studies examining the health outcomes of diabetes mellitus (DM) patients found that social determinants of health disparities were associated with variabilities in health outcomes. However, improving access to healthcare, such as health insurance, should mitigate negative health outcomes. The aim of the study was to explore the association between four types of health insurance, namely, Medicare Fee-For-Service (FFS), Medicare Managed Care (MC), Private FFS, and Private MC plans, and the health outcomes of DM patients, controlling for patients' social determinants of health. METHODS: This is a retrospective cross-sectional archival record study to explore the relationships between types of health insurance and health outcomes of DM patients who were at least 65 years old, or the elderly. Data was drawn from the 2012 Maryland Clinical Public Use Data and received an exempt status from our Institutional Review Board. Elderly Maryland residents with chronic DM were included in the study, resulting in a sample size of 43,519 individuals. Predictor variables were four types of insurance and health outcome variables were length of hospital stay (LOS), 30-day readmission, and end-stage renal disease (ESRD). Control variables included hospital characteristics, patient characteristics, and social determinants of health. Student's t-tests determined the statistical differences for the control variables between the types of insurance. Multiple hierarchical regression analysis was applied to test the association between insurance plans and LOS, while logistic regression analyses were applied to test the association between insurance plans with 30-day readmission and ESRD. Statistical significance was set at p < 0.05. RESULTS: t-test results indicated minimal statistical differences between the health statuses of patients enrolled in different insurance plans. After factoring out the control variables, regression analyses indicated that Medicare FFS patients had the worst outcome for LOS, 30-day readmission, and ESRD rates. Although patients on Medicare MC plans had lower LOS, 30-day readmission, and ESRD rates compared to those on Medicare FFS, patients enrolled in Private MC plans had the lowest odds of a 30-day readmission and patients enrolled in Private FFS had the lowest odds of an ESRD. CONCLUSIONS: The data suggests that insurance plans were related to the health outcomes of elderly DM patients after considering their social determinants of health. Specifically, DM patients enrolled in managed care and private insurance plans had better health outcomes compared to those on Medicare FFS plans.

AIM: The purpose is to assess the adequacy of the National Early Warning Score (NEWS) in the emergency department (ED) and the usefulness of the Triage in Emergency Department Early Warning Score (TREWS) that has been developed using the NEWS in the ED. METHODS: In this retrospective observational cohort study, we performed univariable and multivariable regression analyses with 81,520 consecutive ED patients to develop a new scoring system, the TREWS. The primary outcome was in-hospital mortality within 24â¯h, and secondary outcomes were in-hospital mortality within 48â¯h, 7â¯days, and 30â¯days. The prognostic properties of the TREWS were compared with those of the NEWS, Modified Early Warning Score (MEWS), and Rapid Emergency Medicine Score (REMS) using the area under the receiver operating characteristic curve (AUC) technique. RESULTS: The AUC of the TREWS for in-hospital mortality within 24â¯h was 0.906 (95% CI, 0.903-0.908), those of the NEWS, MEWS, and REMS were 0.878 (95% CI, 0.875-0.881), 0.857 (95% CI, 0.854-0.860), and 0.834 (95% CI, 0.831-0.837), respectively. Differences in the AUC between the TREWS and NEWS, the TREWS and MEWS, and the TREWS and REMS were 0.028 (95% CI, 0.022-0.033; pâ¯<â¯.001), 0.049 (95% CI, 0.041-0.057; pâ¯<â¯.001), and 0.072 (95% CI, 0.063-0.080; pâ¯<â¯.001), respectively. The TREWS showed significantly superior performance in predicting secondary outcomes. CONCLUSION: The TREWS predicts in-hospital mortality within 24â¯h, 48â¯h, 7â¯days, and 30â¯days better than the NEWS, MEWS, and REMS for patients arriving at the ED.

OBJECTIVE: Patients with ST-segment elevation myocardial infarction (STEMI) are sometimes boarded in the emergency department (ED) after percutaneous coronary intervention (PCI). We evaluated the effects of direct and indirect admission to the CCU on mortality and the effect on length of stay (LOS) in patients with STEMI. METHOD: This was a retrospective observational study of patients with STEMI between Jan 2014 and Nov 2017. The patients were divided into the direct admission (DA) group, who were admitted into the CCU immediately after PCI, and the indirect admission (IA) group, who were admitted after boarding in the ED. The primary endpoint was in-hospital mortality. Secondary endpoints were 3-month mortality, LOS in CCU and hospital, and LOS under intensive care. RESULTS: During the study period, 780 patients were enrolled and analyzed. The in-hospital mortality rate and 3-month mortality rate were 5.9% (46 patients) and 8.5% (66 patients). The DA group and IA group had similar in-hospital and 3-month mortality rates (Pâ¯=â¯.50, Pâ¯=â¯.28). The median CCU LOS and hospital LOS was similar for both groups (Pâ¯=â¯.28, Pâ¯=â¯.46). However, LOS under in intensive care for the IA group was significantly longer than that of the DA group (DA, 31.9â¯h; IA, 38.7â¯h; Pâ¯<â¯.001). CONCLUSION: This study suggests that direct admission after PCI and indirect admission was not associated with mortality in patients with STEMI. In addition, the stay in ED also appears to be associated with the duration of stay under critical care.

BACKGROUND: The acute medical unit (AMU) provides early specialist care to emergency department patients before inpatient admission. The workflows and skills for successful AMU nursing comprise a hybrid of internal and emergency medicine. PURPOSE: To understand nursing work dynamics in the AMU. METHODS: AMU at a 1,250-bed tertiary academic center in Singapore with 14,000 ED presentations monthly. Retrospective mixed methods study using focus group discussions and surveys. Fifteen nurses across three focus group discussions. Thirty-two physicians and 54 nurses responded to a validated questionnaire. FINDINGS: Focus group discussions transcripts content analyzed by two researchers. Survey items factor analyzed and attitudinal differences between AMU physicians and nurses, and among nurses compared using Student's t- and one-way ANOVA tests. DISCUSSION: AMU nursing staff faced obstacles of inadequate patient information, emergency department onboarding, unbalanced workload, and coworker conflicts, which led to them to develop processes and checklists to manage patient information, patient expectations, and teamwork. CONCLUSION: AMU nursing requires a combination of specialist internal medicine and emergency medicine skills. Training should familiarize nurse workforce with managing patient expectations and multidisciplinary teamwork.

INTRODUCTION: It is difficult to differentiate whether coronary or non-coronary causes in patients with elevated troponin I (TnI) in emergency department (ED). The aim of this study was to develop a clinical decision tool for differentiating a coronary cause in the patients with elevated TnI. METHODS: This was a retrospective observational study that enrolled consecutive ED patients. Patients were included in the study if they were ≥16â¯years of age, had admitted through ED with a medical illness, and TnI levels at initial evaluation in the ED were ≥0.2â¯ng/mL. Patients diagnosed with ST elevation myocardial infarction or congestive heart failure were excluded. Coronary angiography, electrocardiogram, laboratory results, echocardiography, and clinical characteristics were analyzed. RESULTS: Among the included 1441 patients, 603 and 838 patients were categorized into an acute coronary syndrome (ACS) group and non-acute coronary syndrome (non-ACS) group, respectively. The ratio of N-terminal pro-Btype natriuretic peptide (NT-proBNP) to TnI was significantly higher in the non-ACS group compared to the ACS group. The AUC of NT-proBNP/TnI (0.805, 95% CI, 0.784-0.826) was significantly superior to that of NT-proBNP/creatinine kinase-MB, TnI, and NT-proBNP. The patients of the non-ACS group with high levels of TnI and BNP showed more critically ill manifestation at the time of presentation and higher mortality. CONCLUSION: NT-proBNP/TnI may help to distinguish medical patients with elevated TnI whether the elevated TnIs were caused from ACSs or from conditions other than ACS.

INTRODUCTION: Although consultations are essential for delivering safe, high-quality care to patients in emergency departments, they contribute to emergency department patient flow problems and overcrowding which is associated with several adverse outcomes, such as increases in patient mortality and poor quality care. This study aimed to investigate how time flow metrics including emergency department length of stay is influenced by changes to the internal medicine consultation policy. METHOD: This study is a pre- and post-controlled interventional study. We attempted to improve the internal medicine consultation process to be more concise. After the intervention, only attending emergency physicians consult internal medicine chief residents, clinical fellows, or junior staff of each internal medicine subspecialty who were on duty when patients required special care or an admission to internal medicine. RESULTS: Emergency department length of stay of patients admitted to the department of internal medicine prior to and after the intervention decreased from 996.94min to 706.62min. The times from consultation order to admission order and admission order to emergency department departure prior to and after the intervention were decreased from 359.59min to 180.38min and from 481.89min to 362.37min, respectively. The inpatient mortality rates and Inpatient bed occupancy rates prior to and after the intervention were similar. CONCLUSION: The improvements in the internal medicine consultation process affected the flow time metrics. Therefore, more comprehensive and cooperative strategies need to be developed to reduce the time cycle metrics and overcrowding of all patients in the emergency department.

BACKGROUND: Patients with prolonged length of hospital stay (LOS) not only increase their risks of nosocomial infections but also deny other patients access to inpatient care. Hepatobiliary (HPB) malignancies have some of highest incidences in East and Southeast Asia and the management of patients undergoing HPB surgeries have yet to be standardized. With improved neurosurgery techniques for intracranial aneurysms and tumors, neurosurgeries (NS) can be expected to increase. Elective surgeries account for far more operations than emergencies surgeries. Thus, with potentially increased numbers of elective HPB and NS, this study seeks to explore perioperative factors associated with prolonged LOS for these patients to improve safety and quality of practice. METHODS: A retrospective cross-sectional medical record review study from January 2014 to January 2015 was conducted at a 1250-bed tertiary academic hospital in Singapore. All elective HPB and NS patients over 18 years old were included in the study except day and emergency surgeries, resulting in 150 and 166 patients respectively. Prolonged LOS was defined as above median LOS based on the complexity of the surgical procedure. The predictor variables were preoperative, intraoperative, and postoperative factors. Student's t-test and stepwise logistic regression analyses were conducted to determine which factors were associated with prolonged LOS. RESULTS: Factors associated with prolonged LOS for the HPB sample were age and admission after 5 pm but for the NS sample, they were functional status, referral to occupational therapy, and the number of hospital-acquired infections. CONCLUSION: Our findings indicate that preoperative factors had the greatest association with prolonged LOS for HPB and NS elective surgeries even after adjusting for surgical complexity, suggesting that patient safety and quality of care may be improved with better pre-surgery patient preparation and admission practices.

BACKGROUND: Mortality prediction in patients with brain trauma during initial management in the emergency department (ED) is essential for creating the foundation for a better prognosis. OBJECTIVE: This study aimed to create a simple and useful survival predictive model for patients with isolated blunt traumatic brain injury that is easily available in the ED. METHODS: This is a retrospective study based on the trauma registry data of an academic teaching hospital. The inclusion criteria were age ≥ 15 years, blunt and not penetrating mechanism of injury, and Abbreviated Injury Scale (AIS) scores between 1 and 6 for head and 0 for all other body parts. The primary outcome was 30-day survival probability. Internal and external validation was performed. RESULTS: After univariate logistic regression analysis based on the derivation cohort, the final Predictor of Isolated Trauma in Head (PITH) model for survival prediction of isolated traumatic brain injury included Glasgow Coma Scale (GCS), age, and coded AIS of the head. In the validation cohort, the area under the curve of the PITH score was 0.970 (p < 0.0001; 95% confidence interval 0.960-0.978). Sensitivity and specificity were 95% and 81.7% at the cutoff value of 0.9 (probability of survival 90%), respectively. CONCLUSIONS: The PITH model performed better than the GCS; Revised Trauma Score; and mechanism of injury, GCS, age, and arterial pressure. It will be a useful triage method for isolated traumatic brain injury in the early phase of management.

INTRODUCTION: The Revised Trauma Score (RTS) is used worldwide in prehospital practice and in the emergency department (ED) settings to triage trauma patients. The main purpose of this study was to evaluate the value of the RTS plus serum albumin (RTS-A) and to compare it with other existing trauma scores as well as to compare the predictive performance of the Trauma and Injury Severity Score with the RTS-A (TRISS-A) with the original TRISS. METHODS: This was a single center, trauma registry based observational cohort study. Data were collected from consecutive patients with blunt or penetrating injuries who presented to the emergency department of a tertiary referral hospital, between January 2012 and June 2016. 3145 and 2447 patients were assigned to the derivation group and validation group, respectively. Main outcome was in-hospital mortality. RESULTS: Among patients in the derivation group, the median [interquartile range] age was 59 [43-73] years, and 66.7% were male. The area under the receiver operating characteristic curves (AUC) of the RTS-A (0.948; 95% CI: 0.939-0.955) was higher than that of the RTS (0.919; 95% CI: 0.909-0.929). In patients with blunt trauma, the AUC of the TRISS-A (0.960; 95% CI: 0.952-0.967) was significantly higher than that of the original TRISS (0.949; 95% CI: 0.941-0.957). CONCLUSION: The value of the RTS-A predicts the in-hospital mortality of trauma patients better than the RTS, and the TRISS-A is a better mortality predictor compared to the original TRISS in patients with blunt trauma.

BACKGROUND: Hospitals around the world are faced with the issue of boarders in emergency department (ED), patients marked for admission but with no available inpatient bed. Boarder status is known to be associated with delayed inpatient care and suboptimal outcomes. A new care delivery system was developed in our institution where boarders received full inpatient care from a designated medical team, acute medical team (AMT), while still residing at ED. The current study examines the impact of this AMT intervention on patient outcomes. METHODS: We conducted a retrospective quasi-experimental cohort study to analyze outcomes between the AMT intervention and conventional care in a 1250-bed acute care tertiary academic hospital in Singapore. Study participants included patients who received care from the AMT, a matched cohort of patients admitted directly to inpatient wards (non-AMT) and a sample of patients prior to the intervention (pre-AMT group). Primary outcomes were length of hospital stay (LOS), early discharges (within 24 h) and bed placement. Secondary outcomes included unplanned readmissions within 3 months, and patient's bill size. χ2- and Mann-Whitney U tests were used to test for differences between the cohorts on dichotomous and continuous variables respectively. RESULTS: The sample comprised of 2279 patients (1092 in AMT, 1027 in non-AMT, and 160 in pre-AMT groups). Higher rates of early discharge (without significant differences in the readmission rates) and shorter LOS were noted for the AMT patients. They were also more likely to be admitted into a ward allocated to their discipline and had lower bill size compared to non AMT patients. CONCLUSIONS: The AMT intervention improved patient outcomes and resource utilization. This model was noted to be sustainable and provides a potential solution for hospitals' ED boarders who face a gap in inpatient care during their crucial first few hours of admissions while waiting for an inpatient bed.

OBJECTIVE: To review a quality improvement event on the process of sign-outs between the primary and on-call residents. DESIGN: A retrospective qualitative study using semi-structured interviews. SETTING: A tertiary academic medical center in Singapore with 283 inpatient Medicine beds served by 28 consultants, 29 registrars, 45 residents and 30 interns during the day but 5 residents and 3 interns at night. PARTICIPANTS: Residents, registrars and consultants. INTERVENTION: Quality improvement event on sign-out. MAIN OUTCOME: Effectiveness of sign-out comprises exchange of patient information, professional responsibility and task accountability. RESULTS: The following process of sign-outs was noted. Primary teams were accountable to the on-call resident by selecting at-risk patients and preparing contingency plans for sign-out. Structured information exchanged included patient history, active problems and plans of care. On-call residents took ownership of at-risk patients by actively asking questions during sign-out and reporting back the agreed care plan. On-call residents were accountable to the primary team by reporting back at-risk patients the next day. CONCLUSION: A structured information exchange at sign-out increased the on-call resident's ability to care for at-risk patients when it was supported by two-way transfers of responsibility and accountability.

BACKGROUND: Since its introduction, the Revised Trauma Score (RTS) has been widely used to determine the prognosis of trauma patients. Recent studies have revealed a need to change the parameters of the RTS. We have designed a new trauma score (NTS) based on revised parameters, including the adoption of the actual Glasgow Coma Scale (GCS) score instead of a GCS code, the revision of the systolic blood pressure interval used for the code value and the incorporation of peripheral oxygen saturation (SpO2) instead of respiratory rate. The purpose of this study was to evaluate the predictive performance of the NTS for in-hospital mortality compared with the RTS and other trauma scores. METHODS: This was a prospective observational study using data from the trauma registry of a tertiary hospital. The subjects were selected from patients who arrived at the ED between July 1, 2014, and June 30, 2016, and, for external validation purposes, those who arrived at the ED between July 1, 2011, and June 30, 2013. Demographic data and physiological data were analyzed. NTS models were calculated using logistic regression for GCS score, SBP code values, and SpO2. The mortality predictive performance of NTS was compared with that of other trauma scores. RESULTS: A total of 3263 patients for derivation and 3106 patients for validation were included in the analysis. The NTS showed better discrimination than the RTS (AUC = 0.935 vs. 0.917, respectively, AUC difference = 0.018, p = 0.001; 95% CI, 0.0071-0.0293) and similar discrimination to that of mechanism, Glasgow Coma scale, age, and arterial pressure (MGAP) and the Glasgow Coma Scale, age, and systolic arterial pressure (GAP). In the validation cohort, the global properties of the NTS for mortality prediction were significantly better than those of the RTS (AUC = 0.919 vs. 0.906, respectively; AUC difference = 0.013, p = 0.013; 95% CI, 0.0009-0.0249) and similar to those of the MGAP and GAP. CONCLUSIONS: The NTS predicts in-hospital mortality substantially better than the RTS.

BACKGROUND: The leading cause of surgical pneumoperitoneum is hollow viscus perforation, which accounts for approximately 90% of cases. A nonsurgical etiology may account for up to about 10% of the causes of pneumoperitoneum. However, a pneumoperitoneum often poses significant management dilemmas for surgeons, especially when signs of peritonitis are absent or when the cause is unknown prior to laparotomy. We present the first case of pneumoperitoneum due to inguinal laceration without viscus perforation after a traffic accident. CASE REPORT: A 17-year-old male patient was admitted to the emergency department with a deep laceration of 7â¼8 cm with bleeding in the right inguinal region after a collision with a passenger car while riding a bicycle. The abdominal examination revealed diffuse abdominal tenderness on deep palpation without peritoneal signs. A chest radiograph showed no free gas below the diaphragm. On computed tomography angiography of the aorta, subcutaneous emphysema in the right inguinal and femoral areas and free air in the peritoneal cavity were observed. There was no bowel perforation in an exploratory laparotomy, but the right femoral sheath ruptured, and exposure of the femoral vessels into the peritoneal cavity was observed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A pneumoperitoneum can be caused by femoral sheath rupture without hollow viscus perforation in patients with a penetrating groin injury. Therefore, emergency physicians should not pursue solely abdominal/pelvic sources of a pneumoperitoneum in patients with a penetrating groin injury.

OBJECTIVE: This study was performed to determine a landmark for chest compression depth for adult cardiopulmonary resuscitation (CPR) using chest computed tomography and to evaluate the validity of the landmark. METHODS: The external anteroposterior diameters (EAPDs) of each chest at the suprasternal notch (SN) and the lower half (LH) of the sternum were measured. We analyzed the differences in the EAPDs between the LH and the SN in each EAPD group in the LH of the sternum as follows: less than 20.00, 20.00 to 21.99, 22.00 to 23.99, greater than or equal to 24.00. We compared the differences in the EAPDs between the 2 points with 50 mm and the chest compression depth on simulated one-fourth external chest compressions for each EAPD group on the LH of the sternum. RESULTS: The mean difference in the EAPDs between the SN and the LH was 5.16 ± 0.91 mm. The differences in the EAPDs between the SN and the LH of the sternum with 50 mm did not indicate a significant difference. The mean one-fourth EAPD at the LH of the sternum was 5.50 ± 0.53 mm. There was not a significant difference in the residual chest depth on one-fourth simulated chest compression for each EAPD group on the LH of the sternum. CONCLUSIONS: The SN may have value as a functional landmark for chest compression depth in adult CPR. Our findings combined with the simulated one-fourth chest compressions were more consistent with the depth between 50 and 60 mm recommended by the 2015 CPR guidelines.

BACKGROUND: The context of the study is the Agency for Healthcare Research and Quality's Hospital Survey on Patient Safety Culture (HSOPSC). The purpose of the study is to analyze how different elements of patient safety culture are associated with clinical handoffs and perceptions of patient safety. METHODS: The study was performed with hierarchical multiple linear regression on data from the 2010 Survey. We examine the statistical relationships between perceptions of handoffs and transitions practices, patient safety culture, and patient safety. We statistically controlled for the systematic effects of hospital size, type, ownership, and staffing levels on perceptions of patient safety. RESULTS: The main findings were that the effective handoff of information, responsibility, and accountability were necessary to positive perceptions of patient safety. Feedback and communication about errors were positively related to the transfer of patient information; teamwork within units and the frequency of events reported were positively related to the transfer of personal responsibility during shift changes; and teamwork across units was positively related to the unit transfers of accountability for patients. CONCLUSIONS: In summary, staff views on the behavioral dimensions of handoffs influenced their perceptions of the hospital's level of patient safety. Given the known psychological links between perception, attitude, and behavior, a potential implication is that better patient safety can be achieved by a tight focus on improving handoffs through training and monitoring.

OBJECTIVE: This study was conducted to evaluate the appropriateness of the chest compression (CC) depth recommended in the current guidelines and simulated external CCs, and to characterize the optimal CC depth for an adult by body mass index (BMI). METHODS: Adult patients who underwent chest computed tomography as a screening test for latent pulmonary diseases in the health care center were enrolled in this study. We calculated the internal anteroposterior (AP) diameter (IAPD) and external AP diameter (EAPD) of the chest across BMIs (<18.50, 18.50-24.99, 25.00-29.99, and ≥30.00 kg/m(2)) for simulated CC depth. We also calculated the residual chest depths less than 20 mm for simulated CC depth. RESULTS: There was a statistically significant difference in the chest EAPD and IAPD measured at the lower half of the sternum for each BMI groups (EAPD: R(2) = 0.638, P < .001; IAPD: R(2) = 0.297, P < .001). For one-half external AP CC, 100% of the patients, regardless of BMI, had a calculated residual internal chest depth less than 20 mm. For one-fourth external AP CC, no patients had a calculated residual internal chest depth less than 20 mm. For one-third external AP CC, only 6.48% of the patients had a calculated residual internal chest depth less than 20 mm. CONCLUSIONS: It is not appropriate that the current CC depth (≥50 mm), expressed only as absolute measurement without a fraction of the depth of the chest, is applied uniformly in all adults. In addition, in terms of safety and efficacy, simulated CC targeting approximately between one-third and one-fourth EAPD CC depth might be appropriate.
