Project description:BackgroundDespite potential concerns regarding their validity, physician-rating websites continue to grow in number and utilization and feature prominently on major search engines, potentially affecting patient decision-making regarding physician selection.Questions/purposesWe sought to determine whether patient ratings on public physician-rating websites correlate with surgeon-specific outcomes for high-volume total knee replacement (TKR) surgeons in New York State (NYS) from 2010 to 2012.MethodsOnline patient ratings were compared to surgeon-specific outcomes from the Statewide Planning and Research Cooperative System (SPARCS) database from the NYS Department of Health. For each surgeon, we determined the infection rate, re-admission rate, and revision surgery rate within the study period, as well as the mean inpatient length of stay, for TKR from the SPARCS database. Online ratings were collected from two physician-rating websites (Vitals.com and HealthGrades.com).ResultsOne hundred seventy-four high-volume TKR surgeons were identified in NYS from 2010 to 2012. The mean rates of in-hospital infection, 90-day infection, 30-day re-admission, 90-day re-admission, and revision surgery were 0.25, 1.00, 4.89, 8.43, and 1.31%, respectively. The mean number of ratings for individual surgeons on HealthGrades.com and Vitals.com were 24.0 (range: 0 to 109) and 19.3 (range: 0 to 114), respectively, and mean overall ratings were 4.2 and 4.1 (out of 5) stars, respectively. As with online patient ratings of individual surgeons, variability was observed in the total adverse event rate distribution for individual surgeons. Despite sufficient variability in both online patient rating and surgeon-specific outcomes for high-volume TKR surgeons in NYS, no correlation was observed.ConclusionThere was no correlation between surgeon-specific TKR outcome measures and online patient ratings. We therefore advise that patients exert caution when interpreting ratings on these websites.

Project description:Care coordination is a crucial component of healthcare systems. However, little is known about data needs and uses in ambulatory care coordination practice. Therefore, the purpose of this study was to identify information gathered and used to support care coordination in ambulatory settings. Survey respondents (33) provided their demographics and practice patterns, including use of electronic health records, as well as data gathered and used. Most of the respondents were nurses, and they described varying practice settings and patterns. Although most described at least partial use of electronic health records, two respondents described paper documentation systems. More than 25% of respondents gathered and used most of the 72 data elements, with collection and use often occurring in multiple locations and contexts. This early study demonstrates significant heterogeneity in ambulatory care coordination data usage. Additional research is necessary to identify common data elements to support knowledge development in the context of a learning health system.

Project description:Jumping to conclusions (JTC) is associated with psychotic disorder and psychotic symptoms. If JTC represents a trait, the rate should be (i) increased in people with elevated levels of psychosis proneness such as individuals diagnosed with borderline personality disorder (BPD), and (ii) show a degree of stability over time.The JTC rate was examined in 3 groups: patients with first episode psychosis (FEP), BPD patients and controls, using the Beads Task. PANSS, SIS-R and CAPE scales were used to assess positive psychotic symptoms. Four WAIS III subtests were used to assess IQ.A total of 61 FEP, 26 BPD and 150 controls were evaluated. 29 FEP were revaluated after one year. 44% of FEP (OR = 8.4, 95% CI: 3.9-17.9) displayed a JTC reasoning bias versus 19% of BPD (OR = 2.5, 95% CI: 0.8-7.8) and 9% of controls. JTC was not associated with level of psychotic symptoms or specifically delusionality across the different groups. Differences between FEP and controls were independent of sex, educational level, cannabis use and IQ. After one year, 47.8% of FEP with JTC at baseline again displayed JTC.JTC in part reflects trait vulnerability to develop disorders with expression of psychotic symptoms.

Project description:ImportancePostoperative complications remain common after surgery, but little is known about the extent of variation in operative technical skill and whether variation is associated with patient outcomes.ObjectivesTo examine the (1) variation in technical skill scores of practicing surgeons, (2) association between technical skills and patient outcomes, and (3) amount of variation in patient outcomes explained by a surgeon's technical skill.Design, setting, and participantsIn this quality improvement study, 17 practicing surgeons submitted a video of a laparoscopic right hemicolectomy that was then rated by at least 10 blinded peer surgeons and 2 expert raters. The association between surgeon technical skill scores and risk-adjusted outcomes was examined using data from the American College of Surgeons National Surgical Quality Improvement Program. The association between technical skill scores and outcomes was examined for colorectal procedures and noncolorectal procedures (ie, assessed on whether technical skills demonstrated during colectomy were associated with patient outcomes across other cases). In addition, the proportion of patient outcomes explained by technical skill scores was examined using robust regression techniques. The study was conducted from September 23, 2016, to February 10, 2018; data analysis was performed from November 2018 to January 2019.ExposuresColorectal and noncolorectal procedures.Main outcomes and measuresAny complication, mortality, unplanned hospital readmission, unplanned reoperation related to principal procedure, surgical site infection, and death or serious morbidity.ResultsOf the 17 surgeons included in the study, 13 were men (76%). The participants had a range from 1 to 28 years in surgical practice (median, 11 years). Based on 10 or more reviewers per video and with a maximum quality score of 5, overall technical skill scores ranged from 2.8 to 4.6. From 2014 to 2016, study participants performed a total of 3063 procedures (1120 colectomies). Higher technical skill scores were significantly associated with lower rates of any complication (15.5% vs 20.6%, P = .03; Spearman rank-order correlation coefficient r = -0.54, P = .03), unplanned reoperation (4.7% vs 7.2%, P = .02; r = -0.60, P = .01), and a composite measure of death or serious morbidity (15.9% vs 21.4%, P = .02; r = -0.60, P = .01) following colectomy. Similar associations were found between colectomy technical skill scores and patient outcomes for all types of procedures performed by a surgeon. Overall, technical skill scores appeared to account for 25.8% of the variation in postcolectomy complication rates and 27.5% of the variation when including noncolectomy complication rates.Conclusions and relevanceThe findings of this study suggest that there is wide variation in technical skill among practicing surgeons, accounting for more than 25% of the variation in patient outcomes. Higher colectomy technical skill scores appear to be associated with lower complication rates for colectomy and for all other procedures performed by a surgeon. Efforts to improve surgeon technical skills may result in better patient outcomes.

Project description:A variety of deep learning techniques are actively employed for advanced driver assistance systems, which in turn require gathering lots of heterogeneous driving data, such as traffic conditions, driver behavior, vehicle status and location information. However, these different types of driving data easily become more than tens of GB per day, forming a significant hurdle due to the storage and network cost. To address this problem, this paper proposes a novel scheme, called CoDR, which can reduce data volume by considering the correlations among heterogeneous driving data. Among heterogeneous datasets, CoDR first chooses one set as a pivot data. Then, according to the objective of data collection, it identifies data ranges relevant to the objective from the pivot dataset. Finally, it investigates correlations among sets, and reduces data volume by eliminating irrelevant data from not only the pivot set but also other remaining datasets. CoDR gathers four heterogeneous driving datasets: two videos for front view and driver behavior, OBD-II and GPS data. We show that CoDR decreases data volume by up to 91%. We also present diverse analytical results that reveal the correlations among the four datasets, which can be exploited usefully for edge computing to reduce data volume on the spot.

Project description:Given the rising costs of health care in today's economic environment, the need for effective, value-driven care has never been more pressing. While the U.S. health care system strives continually to improve patient outcomes, it struggles with the inadequacies due to variation in care and the inefficiencies of unnecessary resource utilization. The tools traditionally used to study care, from retrospective studies to randomized controlled trials, may be inadequate to address the complicated, interdependent questions related to defining effective care. To overcome the deficiencies of these traditional tools and better optimize our health care system, a new kind of methodology is required--one that integrates the functionality of previously existing tools in a novel way. Standardized Clinical Assessment and Management Plans (SCAMPs) were designed to accomplish this goal. A SCAMP is a care pathway, designed by clinicians, to guide medical decision making around a particular disorder. SCAMPs are unique in that they invite knowledge-based diversions from their recommendations and are accompanied by data collection and continuous improvement processes. Through these mechanisms, SCAMPs successfully reduce practice variation, optimize resource use, and create an integrated medical learning system which overcomes many of the inadequacies of traditional research tools. As such, the SCAMP paradigm may represent an important breakthrough in the effort to define and implement effective health care.

Project description:BackgroundThere is evidence for a group of nonclinical individuals with full-blown, persistent psychotic experiences (PEs) but no need-for-care: they are of particular importance in identifying risk and protective factors for clinical psychosis. The aim of this study was to investigate whether reasoning biases are related to PEs or need-for-care.MethodTwo groups with persistent PEs (clinical; n = 74; nonclinical; n = 92) and a control group without PEs (n = 83) were compared on jumping-to-conclusions (JTC) and belief flexibility. A randomly selected subset of interviews (n = 104) was analyzed to examine differences in experiential and rational reasoning.ResultsAs predicted JTC was more common in the clinical than the other 2 groups. Unexpectedly no group differences were observed between clinical and nonclinical groups on measures of belief flexibility. However, the clinical group was less likely to employ rational reasoning, while the nonclinical group was more likely to use experiential reasoning plus a combination of both types of reasoning processes, compared to the other 2 groups.ConclusionsReasoning biases differ in groups with PEs with and without need-for-care. JTC is associated with need-for-care rather than with PEs. The ability to invoke rational reasoning processes, together with an absence of JTC, may protect against pathological outcomes of persistent PEs. However, marked use of experiential reasoning is associated with the occurrence of PEs in both clinical and nonclinical groups. Implications for theory development, intervention and further research are discussed.

Project description:ObjectiveTherapeutic targets in Idiopathic Inflammatory Myopathies (IIM) are based on the opinions of physicians/specialists, which may not reflect the main concerns of patients. The authors, therefore, assessed the outcome concerns of patients with IIM and compared them with the concerns of rheumatologists in order to develop an IIM outcome standard set.MethodsNinety-three IIM patients, 51 rheumatologists, and one physiotherapist were invited to participate. An open questionnaire was initially applied. The top 10 answers were selected and applied in a multiple-choice questionnaire, inquiring about the top 3 major concerns. Answers were compared, and the agreement rate was calculated. Concerns were gathered in an IIM outcome standard set with validated measures.ResultsThe top three outcome concerns raised by patients were medication side effects/muscle weakness/prevention functionality loss. The top three concerns among rheumatologists were to prevent loss of functionality/to ensure the quality of life/to achieve disease remission. Other's outcomes concerns only pointed out by patients were muscle pain/diffuse pain/skin lesions/fatigue. The agreement rate between both groups was 41%. Assessment of these parameters guided the development of an IIM standard set which included Myositis Disease Activity Assessment Visual Analogue Scale/Manual Muscle Testing/fatigue and pain Global Visual Analogue Scale/Health Assessment Questionnaire/level of physical activity.ConclusionThe authors propose a novel standard set to be pursued in IIM routine follow-up, which includes not only the main patients/rheumatologist outcome concerns but also additional important outcomes only indicated by patients. Future studies are necessary to confirm if this comprehensive approach will result in improved adherence and ultimately in better assistance.

Project description:The objective of this investigation was to evaluate endoscopic sinus surgery (ESS) outcomes for chronic rhinosinusitis (CRS) between medical centers to determine if differences in quality-of-life outcomes were detectable. In addition, we sought to identify significant, independent cofactors toward the development of an ESS-specific risk-adjustment model so that ESS outcomes may be appropriately compared between institutions and healthcare providers.Prospective, multicenter, observational cohort.Study participants electing ESS for CRS were enrolled and randomly selected in equal numbers from three academic clinical practices in North America between April 2011 and May 2015. The magnitude of average 6-month postoperative improvement in patient-related outcome measures (PROMs) was compared between enrollment sites using multivariate linear regression modeling.A total of 228 participants met inclusion criteria and were included for final analyses (n = 76 per site). The prevalence of septal deviation/septoplasty and oral corticosteroid-dependent conditions was significantly different between enrollment sites (P ? 0.004). Each enrollment site generated significant within-subject improvement across all PROMs after ESS (P < 0.001); however, average unadjusted magnitudes of improvement were significantly different between sites for the primary outcome measure. After controlling for baseline PROMs, septal deviation, steroid-dependent conditions, and medication use variables, enrollment site was no longer associated with significant outcome differences (P = 0.535).Comparison of surgeon outcomes of ESS is feasible and must take into account a number of baseline patient characteristics. Further studies will be critical toward developing an ESS-specific risk-adjustment model and enabling a robust comparison of surgeon outcomes.2c. Laryngoscope, 127:14-21, 2017.

Project description:BackgroundMost studies showing a volume outcome effect in resection surgery for oesophago-gastric cancer were conducted before the centralisation of clinical services. This study evaluated the relation between hospital- and surgeon volume and different risk-adjusted outcomes after oesophago-gastric (OG) cancer surgery in England between 2011 and 2013.MethodsIn data from the National Oesophago-Gastric Cancer Audit from the UK, multivariable random-effects logistic regression models were used to quantify the effect of surgeon and hospital volume on three outcomes: 30-day and 90-day mortality and anastomotic leakage. The models included patient risk factors to adjust for differences in case-mix among hospitals and surgeons. The between-cluster heterogeneity was estimated with the median odds ratio (MOR).ResultsThe study included patients treated at 42 hospitals and 329 surgeons. The median (interquartile range) of the annual hospital and surgeon volumes were 110 patients (82 to 137) and 13 patients (8 to 19), respectively. The overall rates for 30-day and 90-day mortality were 2.3% and 4.4% respectively, and the anastomotic leakage was 6.3%. Higher hospital volume was associated with lower 30-day mortality (OR: 0.94; 95% CI: 0.91-0.98) and lower anastomotic leakage rates (OR: 0.96; 95% CI: 0.93-0.98) but not 90-day mortality. Higher surgeon volume was only associated with lower anastomotic leakage rates (OR: 0.81; 95% CI: 0.72-0.92). Hospital volume explained a part of the between-hospital variation in 30-day mortality whereas surgeon volume explained part of the between-hospital variation in anastomotic leakage.ConclusionsIn the setting of centralized O-G cancer surgery in England, we could still observe an effect of volume on short-term outcomes. However, the effect is inconsistent, depending on the type of outcome measure under consideration, and much smaller than in previous studies. Efforts to centralise O-G cancer services further should carefully address the effects of both hospital and surgeon volume on the range of outcome measures that are relevant to patients.
