Objective To assess readmission rates identified by 3M-Potentially Preventable Readmissions software (3M-PPRs) in a national cohort of children's hospitals. Study design A total of 1 719 617 ...hospitalizations for 1 531 828 unique patients in 58 children's hospitals from 2009 to 2011 from the Children's Hospital Association Case-Mix Comparative database were examined. Main outcome measures included rates, diagnoses, and costs of potentially preventable readmissions (PPRs) and all-cause readmissions. Results The 7-, 15-, and 30-day rates by 3M-PPRs were 2.5%, 4.1%, and 6.2%, respectively. Corresponding all-cause readmission rates were 5.0%, 8.7%, and 13.3%. At 30 days, 60.6% of all-cause readmissions were considered nonpreventable by 3M-PPRs, more than one-half of which were related to malignancies. The percentage of readmissions rated as potentially preventable was similar at all 3 time intervals. Readmissions after chemotherapy, acute leukemia, and cystic fibrosis were all considered nonpreventable, and at least 80% of readmissions after index admissions for sickle cell crisis, bronchiolitis, ventricular shunt procedures, asthma, and appendectomy were designated potentially preventable. Total costs for all readmissions were $1.7 billion; PPRs accounted for 27.3% of these costs. The most costly readmissions were associated with ventricular shunt procedures ($26.5 million/year), seizures ($15.5 million/year), and sickle cell crisis ($15.0 million/year). Conclusions Rates of PPRs were significantly lower than all-cause readmission rates more than one-half of which were caused by exclusion of malignancies. Annual costs of PPRs, although significant in the aggregate, appear to represent a much smaller cost-savings opportunity for children than for adults. Our study may help guide children's hospitals to focus readmission reduction strategies on areas where the financial vulnerability is greatest based on 3M-PPRs.
Patient-centred outcomes are increasingly used in perioperative clinical trials. The Standardised Endpoints in Perioperative Medicine (StEP) initiative aims to define which measures should be used in ...future research to facilitate comparison between studies and to enable robust evidence synthesis.
A systematic review was conducted to create a longlist of patient satisfaction, health-related quality of life, functional status, patient well-being, and life-impact measures for consideration. A three-stage Delphi consensus process involving 89 international experts was then conducted in order to refine this list into a set of recommendations.
The literature review yielded six patient-satisfaction measures, seven generic health-related quality-of-life measures, eight patient well-being measures, five functional-status measures, and five life-impact measures for consideration. The Delphi response rates were 92%, 87%, and 100% for Rounds 1, 2, and 3, respectively. Three additional measures were added during the Delphi process as a result of contributions from the StEP group members. Firm recommendations have been made about one health-related quality-of-life measure (EuroQol 5 Dimension, five-level version with visual analogue scale), one functional-status measure (WHO Disability Assessment Schedule version 2.0, 12-question version), and one life-impact measure (days alive and out of hospital at 30 days after surgery). Recommendations with caveats have been made about the Bauer patient-satisfaction measure and two life-impact measures (days alive and out of hospital at 1 yr after surgery, and discharge destination).
Several patient-centred outcome measures have been recommended for use in future perioperative studies. We suggest that every clinical study should consider using at least one patient-centred outcome within a suite of endpoints.
Summary
Healthcare workers involved in aerosol‐generating procedures, such as tracheal intubation, may be at elevated risk of acquiring COVID‐19. However, the magnitude of this risk is unknown. We ...conducted a prospective international multicentre cohort study recruiting healthcare workers participating in tracheal intubation of patients with suspected or confirmed COVID‐19. Information on tracheal intubation episodes, personal protective equipment use and subsequent provider health status was collected via self‐reporting. The primary endpoint was the incidence of laboratory‐confirmed COVID‐19 diagnosis or new symptoms requiring self‐isolation or hospitalisation after a tracheal intubation episode. Cox regression analysis examined associations between the primary endpoint and healthcare worker characteristics, procedure‐related factors and personal protective equipment use. Between 23 March and 2 June 2020, 1718 healthcare workers from 503 hospitals in 17 countries reported 5148 tracheal intubation episodes. The overall incidence of the primary endpoint was 10.7% over a median (IQR range) follow‐up of 32 (18–48 0–116) days. The cumulative incidence within 7, 14 and 21 days of the first tracheal intubation episode was 3.6%, 6.1% and 8.5%, respectively. The risk of the primary endpoint varied by country and was higher in women, but was not associated with other factors. Around 1 in 10 healthcare workers involved in tracheal intubation of patients with suspected or confirmed COVID‐19 subsequently reported a COVID‐19 outcome. This has human resource implications for institutional capacity to deliver essential healthcare services, and wider societal implications for COVID‐19 transmission.
Objective To compare the complexity and severity of presentation of children in general vs pediatric emergency departments (EDs). Study design We performed a cross-sectional study of pediatric ED ...visits using the National Emergency Department Sample from 2008 to 2012. We classified EDs as “pediatric” if >75% of patients were <18 years old; all other EDs were classified as “general.” The presence of an International Classification of Diseases, Ninth Revision code for a complex chronic condition was used as an indicator of patient complexity. Patient severity was evaluated with the severity classification system. In addition, rates of critical procedures and hospitalization were assessed. Results We identified 9.6 million encounters to pediatric EDs and 169 million to general EDs. Younger children account for a greater proportion of visits at pediatric EDs than general EDs; children <1 year of age account for 18% of visits to a pediatric ED compared with 9% of visits to a general ED ( P < .01). Encounters at pediatric EDs had greater complexity (5% vs. 2%; P < .01). Although severity classification system scores did not significantly differ by ED type, pediatric EDs had greater rates of hospitalization (10% vs 4%). Conclusions Pediatric EDs provided care to a greater proportion of medically complex children than general EDs and had greater rates of hospitalization. This information may inform educational efforts in residency or postgraduate training to ensure high-quality care for children with complex health care needs.
Study objective We determine the optimal correction factor for cerebrospinal fluid WBC counts in infants with traumatic lumbar punctures. Methods We performed a secondary analysis of a retrospective ...cohort of infants aged 60 days or younger and with a traumatic lumbar puncture (cerebrospinal fluid RBC count ≥10,000 cells/mm3 ) at 20 participating centers. Cerebrospinal fluid pleocytosis was defined as a cerebrospinal fluid WBC count greater than or equal to 20 cells/mm3 for infants aged 28 days or younger and greater than or equal to 10 cells/mm3 for infants aged 29 to 60 days; bacterial meningitis was defined as growth of pathogenic bacteria from cerebrospinal fluid culture. Using linear regression, we derived a cerebrospinal fluid WBC correction factor and compared the uncorrected with the corrected cerebrospinal fluid WBC count for the detection of bacterial meningitis. Results Of the eligible 20,319 lumbar punctures, 2,880 (14%) were traumatic, and 33 of these patients (1.1%) had bacterial meningitis. The derived cerebrospinal fluid RBCs:WBCs ratio was 877:1 (95% confidence interval CI 805 to 961:1). Compared with the uncorrected cerebrospinal fluid WBC count, the corrected one had lower sensitivity for bacterial meningitis (88% uncorrected versus 67% corrected; difference 21%; 95% CI 10% to 37%) but resulted in fewer infants with cerebrospinal fluid pleocytosis (78% uncorrected versus 33% corrected; difference 45%; 95% CI 43% to 47%). Cerebrospinal fluid WBC count correction resulted in the misclassification of 7 additional infants with bacterial meningitis, who were misclassified as not having cerebrospinal fluid pleocytosis; only 1 of these infants was older than 28 days. Conclusion Correction of the cerebrospinal fluid WBC count substantially reduced the number of infants with cerebrospinal fluid pleocytosis while misclassifying only 1 infant with bacterial meningitis of those aged 29 to 60 days.
Objectives To evaluate accuracy of 2 established administrative methods of identifying children with sepsis using a medical record review reference standard. Study design Multicenter retrospective ...study at 6 US children's hospitals. Subjects were children >60 days to <19 years of age and identified in 4 groups based on International Classification of Diseases, Ninth Revision, Clinical Modification codes: (1) severe sepsis/septic shock (sepsis codes); (2) infection plus organ dysfunction (combination codes); (3) subjects without codes for infection, organ dysfunction, or severe sepsis; and (4) infection but not severe sepsis or organ dysfunction. Combination codes were allowed, but not required within the sepsis codes group. We determined the presence of reference standard severe sepsis according to consensus criteria. Logistic regression was performed to determine whether addition of codes for sepsis therapies improved case identification. Results A total of 130 out of 432 subjects met reference SD of severe sepsis. Sepsis codes had sensitivity 73% (95% CI 70-86), specificity 92% (95% CI 87-95), and positive predictive value 79% (95% CI 70-86). Combination codes had sensitivity 15% (95% CI 9-22), specificity 71% (95% CI 65-76), and positive predictive value 18% (95% CI 11-27). Slight improvements in model characteristics were observed when codes for vasoactive medications and endotracheal intubation were added to sepsis codes (c-statistic 0.83 vs 0.87, P = .008). Conclusions Sepsis specific International Classification of Diseases, Ninth Revision, Clinical Modification codes identify pediatric patients with severe sepsis in administrative data more accurately than a combination of codes for infection plus organ dysfunction.
Background Minimally invasive inguinal lymphadenectomy (MILND) is a novel procedure with the potential to decrease surgical morbidity compared with the traditional open approach. The current study ...examined the feasibility of a combined didactic and hands-on training program to prepare high-volume melanoma surgeons to perform this procedure safely and proficiently. Study Design A select group of melanoma surgeons with no MILND experience were recruited. After completing a structured training program, surgeons enrolled patients with melanoma who required inguinal lymphadenectomy and performed the procedure in the minimally invasive fashion. A proficiency score composed of lymph node yield, operative time, and blood loss (or adverse events) was assigned for each case. After performing six cases, surgeons meeting a threshold score were considered proficient in the procedure. Results Twelve surgeons from 10 institutions enrolled 88 patients. The majority of surgeons were deemed proficient within 6 cases (83%). No differences in operative time or lymph node yield were noted during the course of the study. The rate of conversion was higher during an individual surgeon's early experience (9 of 49 18%), and only 1 procedure was converted in the 39 cases performed after a surgeon had performed 5 cases (late conversion rate, 3%; p = 0.038); however, this did not remain significant after controlling for surgeon. Conclusions After a structured training program, experienced melanoma surgeons adopted a novel surgical technique with acceptable operative times, conversions, and lymph node yield. Eighty-four percent of the surgeons who completed at least 6 MILND procedures were considered proficient based on our predetermined definition.
Abstract Background Context Blood transfusions in spine surgery are shown to be associated with increased patient morbidity. The association between transfusion performed using a liberal hemoglobin ...trigger—defined as an intraoperative hemoglobin level of ≥10 g/dL, a postoperative level of ≥8 g/dL, or a whole hospital nadir between 8-10 g/dL—and perioperative morbidity and cost in spine surgery patients is unknown and thus was investigated in this study. Purpose To describe the perioperative outcomes and economic cost associated with liberal hemoglobin trigger transfusion among spine surgery patients. Study Design/Setting Retrospective study. Patient Sample The surgical billing database at our institution was queried for inpatients discharged between 2008 and 2015 after the following procedures: atlantoaxial fusion, anterior cervical fusion, posterior cervical fusion, anterior lumbar fusion, posterior lumbar fusion, lateral lumbar fusion, other procedures, and tumor-related surgeries. In total, 6931 patients were included for analysis. Outcome Measures The primary outcome was composite morbidity which was comprised of: (1) infection (sepsis, surgical-site infection, Clostridium dificile, or drug-resistant infection), (2) thrombotic event (pulmonary embolus, deep venous thrombosis, or disseminated intravascular coagulation), (3) kidney injury, (4) respiratory event, and/or (5) ischemic event (transient ischemic attack, myocardial infarction, or cerebrovascular accident). Methods Data on intraoperative transfusion were obtained from an automated prospectively collected anesthesia data management system. Data on postoperative hospital transfusion was obtained through a Web-based intelligence portal. Based on previous research, we analyzed the data using three definitions of a liberal transfusion trigger in patients who received an RBC transfusion: a liberal intraoperative Hb trigger as a nadir Hb level of 10 g/dL or greater, a liberal postoperative Hb trigger as a nadir Hb level of 8 g/dL or greater, or a whole hospital nadir Hb level of 8-10 g/dL. Variables analyzed included in-hospital morbidity, mortality, length of stay, and total costs associated with a liberal transfusion strategy. Results Among patients with a whole hospital stay nadir hemoglobin between 8 to 10 g/dL, transfused patients demonstrated a longer in-hospital stay (median IQR, 6 5-9 vs. 4 3-6 days; P<0.0001) and a higher perioperative morbidity (n=145, 11.5% vs. n=74, 6.1%; P<0.0001) than those not transfused. Even after adjusting for age, gender, race, ASA class, CCI score, estimated blood loss, baseline hemoglobin value, number of operated levels, and surgery type, logistic regression analysis revealed that patients with a nadir hemoglobin of 8-10 g/dL who were transfused had an independently higher risk of perioperative morbidity (odds ratio OR = 2.12; 95% confidence interval CI, 1.24-3.64; P=0.006). Estimated additional costs associated with liberal trigger use, defined as a transfusion occurring in patients with a whole hospital stay nadir Hb of 8-10 g/dL, ranged from $202,675 to $700,151 annually. Conclusions Transfusion using a liberal trigger is associated with increased morbidity, even after controlling for possible confounders. Our results suggest that modification of transfusion practice may be a potential area for improving patient outcomes and reducing costs.
Objective To assess the impact of chronic conditions on children's emergency department (ED) use. Study design Retrospective analysis of 1 850 027 ED visits in 2010 by 3 250 383 children ages 1-21 ...years continuously enrolled in Medicaid from 10 states included in the Truven Marketscan Medicaid Database. The main outcome was the annual ED visit rate not resulting in hospitalization per 1000 enrollees. We compared rates by enrollees' characteristics, including type and number of chronic conditions, and medical technology (eg, gastrostomy, tracheostomy), using Poisson regression. To assess chronic conditions, we used the Agency for Healthcare Research and Quality's Chronic Condition Indicator system, assigning chronic conditions with ED visit rates ≥75th percentile as having the “highest” visit rates. Results The overall annual ED visit rate was 569 per 1000 enrollees. As the number of the children's chronic conditions increased from 0 to ≥3, visit rates increased by 180% (from 376 to 1053 per 1000 enrollees, P < .001). Rates were 174% higher in children assisted with vs without medical technology (1546 vs 565, P < .001). Sickle cell anemia, epilepsy, and asthma were among the chronic conditions associated with the highest ED visit rates (all ≥1003 per 1000 enrollees). Conclusions The highest ED visit rates resulting in discharge to home occurred in children with multiple chronic conditions, technology assistance, and specific conditions such as sickle cell anemia. Future studies should assess the preventability of ED visits in these populations and identify opportunities for reducing their ED use.
