The effect of the Vermont Diabetes Information System on inpatient and emergency room use: results from a randomized trial.

ABSTRACT: OBJECTIVE: To describe the effect of the Vermont Diabetes Information System (VDIS) on hospital and emergency room use DATA SOURCE: Statewide discharge database STUDY DESIGN: Randomized controlled trial of a decision support system for 7,412 adults with diabetes and their 64 primary care providers. DATA COLLECTION/ DATA EXTRACTION: Charges and dates for hospital admissions and emergency room care in Vermont during an average of 32 months of observation. Data from New York hospitals were not available. PRINCIPAL FINDINGS: Patients randomized to VDIS were admitted to the hospital less often than control subjects (0.17 admissions vs. 0.20; P=0.01) and generated lower hospital charges ($3,113 vs. $3,480; P=0.019). VDIS patients also had lower emergency room utilization (0.27 visits vs. 0.36; P<0.0001) and charges ($304 vs. $414; P<0.0001). The intervention was particularly effective in men and in older subjects. CONCLUSIONS: In spite of data limitations that tended to reduce the apparent effect of the system; this randomized, controlled trial showed that VDIS reduces hospitalization and emergency room utilization and expenses.

Project description:We compare rates of rapid HIV testing, test offer, and acceptance in an urban emergency department (ED) when conducted by dedicated HIV counselors versus current members of the ED staff.The Universal Screening for HIV Infection in the Emergency Room [USHER] trial is a prospective randomized controlled trial that implemented an HIV screening program in the ED of an urban tertiary medical center. ED patients were screened and consented for trial enrollment by an USHER research assistant. Eligible subjects were randomized to rapid HIV testing (oral OraQuick) offered by a dedicated counselor (counselor arm) or by an ED provider (provider arm). In the counselor arm, counselors-without other clinical responsibilities-assumed nearly all testing-related activities (consent, counseling, delivery of test results). In the provider arm, trained ED emergency service assistants (nursing assistants) consented and tested the participant in the context of other ED-related responsibilities. In this arm, ED house officers, physician assistants, or attending physicians provided HIV test results to trial participants. Outcome measures were rates of HIV testing and test offer among individuals consenting for study participation. Among individuals offered the test, test acceptance was also measured.From February 2007 through July 2008, 8,187 eligible patients were approached in the ED, and 4,855 (59%) consented and were randomized to trial participation. The mean age was 37 years, 65% were women, and 42% were white. The overall testing rate favored the counselor arm (57% versus 27%; P<.001); 80% (1,959/2,446) of subjects in the counselor arm were offered an HIV test compared with 36% (861/2,409) in the provider arm (P<.001). HIV test acceptance was slightly higher in the provider arm (counselor arm 71% versus provider arm 75%; P = .025).Routine rapid HIV testing in the ED was accomplished more frequently by dedicated HIV counselors than by ED staff in the course of routine clinical work. Without dedicated staff, HIV testing in this setting may not be truly routine.

Project description:Background & objectivesStudies assessing the spatial and temporal association of ambient air pollution with emergency room visits of patients having acute respiratory symptoms in Delhi are lacking. Therefore, the present study explored the relationship between spatio-temporal variation of particulate matter (PM)2.5 concentrations and air quality index (AQI) with emergency room (ER) visits of patients having acute respiratory symptoms in Delhi using the geographic information system (GIS) approach.MethodsThe daily number of ER visits of patients having acute respiratory symptoms (less than or equal to two weeks) was recorded from the ER of four hospitals of Delhi from March 2018 to February 2019. Daily outdoor PM2.5 concentrations and air quality index (AQI) were obtained from the Delhi Pollution Control Committee. Spatial distribution of patients with acute respiratory symptoms visiting ER, PM2.5 concentrations and AQI were mapped for three seasons of Delhi using ArcGIS software.ResultsOf the 70,594 patients screened from ER, 18,063 eligible patients were enrolled in the study. Winter days had poor AQI compared to moderate and satisfactory AQI during summer and monsoon days, respectively. None of the days reported good AQI (<50). During winters, an increase in acute respiratory ER visits of patients was associated with higher PM2.5 concentrations in the highly polluted northwest region of Delhi. In contrast, a lower number of acute respiratory ER visits of patients were seen from the 'moderately polluted' south-west region of Delhi with relatively lower PM2.5 concentrations.Interpretation & conclusionsAcute respiratory ER visits of patients were related to regional PM2.5 concentrations and AQI that differed during the three seasons of Delhi. The present study provides support for identifying the hotspots and implementation of focused, intensive decentralized strategies to control ambient air pollution in worst-affected areas, in addition to the general city-wise strategies.

Project description:BackgroundUltra-low dose computed tomography (ULD-CT) was shown to be a good alternative to digital radiographs in various locations. This study aimed to assess the diagnostic sensitivity and specificity of ULD-CT versus digital radiographs in patients consulting for extremity traumas in emergency room.MethodsDigital radiography and ULD-CT scan were performed in patients consulting at the emergency department (February-August 2018) for extremity traumas. Fracture detection was evaluated retrospectively by two blinded independent radiologists. Sensitivity and specificity were evaluated using best value comparator (BVC) and a Bayesian latent class model (LCM) approaches and clinical follow-up. Image quality, quality diagnostic and diagnostic confidence level were evaluated (Likert scale). The effective dose received was calculated.ResultsSeventy-six consecutive patients (41 men, mean age: 35.2±13.2 years), with 31 wrists/hands and 45 ankles/feet traumas were managed by emergency physicians. According to clinical data, radiography had 3 false positive and 10 false negative examinations, and ULD-CT, 2 of each. Radiography and ULD-CT specificities were similar; sensitivities were lower for radiography, with BVC and Bayesian. With Bayesian, ULD-CT and radiography sensitivities were 90% (95% CI: 87-93%) and 76% (95% CI: 71-81%, P<0.0001) and specificities 96% (95% CI: 93-98%) and 93% (95% CI: 87-97%, P=0.84). The inter-observer agreement was higher for ULD-CT for all subjective indexes. The effective dose for ULD-CT and radiography was 0.84±0.14 and 0.58±0.27 µSv (P=0.002) for hand/wrist, and 1.50±0.32 and 1.44±0.78 µSv (P=NS) for foot/ankle.ConclusionsWith an effective dose level close to radiography, ULD-CT showed better detection of extremities fractures in the emergency room and may allow treatment adaptation. Further studies need to be performed to assess impact of such examination in everyday practice.Trial registrationClinicalTrials.gov Identifier: NCT04832490.
