Assessment of the Utilization of Validated Diagnostic Predictive Tools and D-Dimer in the Evaluation of Pulmonary Embolism: A Single-Center Retrospective Cohort Study from a Public Hospital in New York City.

ABSTRACT:

Introduction

A significant increase in the use of computed tomography with pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) has been observed in the past twenty years. We aimed to investigate whether the validated diagnostic predictive tools and D-dimers were adequately utilized in a large public hospital in New York City.

Methods

We conducted a retrospective review of patients who underwent CTPA for the specific indication of ruling out PE over a period of one year. Two independent reviewers, blinded to each other and to the CTPA and D-dimer results, estimated the clinical probability (CP) of PE using Well's score, the YEARS algorithm, and the revised Geneva score. Patients were classified based on the presence or absence of PE in the CTPA.

Results

A total of 917 patients were included in the analysis (median age: 57 years, female: 59%). The clinical probability of PE was considered low by both independent reviewers in 563 (61.4%), 487 (55%), and 184 (20.1%) patients based on Well's score, the YEARS algorithm, and the revised Geneva score, respectively. D-dimer testing was conducted in less than half of the patients who were deemed to have low CP for PE by both independent reviewers. Using a D-dimer cut-off of <500 ng/mL or the age-adjusted cut-off in patients with a low CP of PE would have missed only a small number of mainly subsegmental PE. All three tools, when combined with D-dimer < 500 ng/mL or 95%.

Conclusion

All three validated diagnostic predictive tools were found to have significant diagnostic value in ruling out PE when combined with a D-dimer cut-off of <500 ng/mL or the age-adjusted cut-off. Excessive use of CTPA was likely secondary to suboptimal use of diagnostic predictive tools.

Project description:ImportanceMore evidence on associations between mandated paid sick leave and health service utilization among low-income adults is needed to guide health policy and legislation nationwide.ObjectiveTo evaluate the association between New York City's 2014 paid sick leave mandate and health care utilization among Medicaid-enrolled adults.Design setting and participantsThis retrospective cohort study used New York State Medicaid administrative data for adults 18 to 64 years old continuously enrolled in Medicaid from August 1, 2011, through July 31, 2017. A difference-in-differences approach with entropy balancing weights was used to compare New York City with the rest of New York State to assess the association of the paid sick leave mandate with health care utilization, and for those 40 to 64 years old, with preventive care utilization. The data analysis was performed from June through August 2020.ExposuresTemporal and spatial variation in exposure to the mandate.Main outcomes and measuresAnnual health care utilization (emergency care, specialist visits, and primary care clinician visits) per Medicaid-enrolled adult. Secondary outcomes include categories of emergency utilization and utilization of 5 preventive services.ResultsOf 552 857 individuals (mean [SD] age, 43 [12] years; 351 130 [64%] women) who met inclusion criteria, 99 181 (18%) were White, 162 492 (29%) Black, and 138 061 (25%) Hispanic. Paid sick leave was significantly associated with a reduction in the probability of emergency care (-0.6 percentage points [pp]; 95% CI, -0.7 to -0.5 pp; P < .001), including a 0.3 pp reduction (95% CI, -0.4 to -0.2; P < .001) in care for conditions treatable in a primary care setting and an increase in annual outpatient visits (0.124 pp; 95% CI, 0.040 to 0.208 pp; P < .001). Among those 40 to 64 years old, the mandate was significantly associated with increased probabilities of glycated hemoglobin A1c level testing (2.9 pp; 95% CI, 2.5-3.3 pp; P < .001), blood cholesterol testing (2.7 pp; 95% CI, 2.5-2.9 pp; P < .001), and colon cancer screening (0.4 pp; 95% CI, 0.2-0.6 pp; P < .001).Conclusions and relevanceThis retrospective cohort study of nonelderly adults enrolled in Medicaid New York State showed that mandated paid sick leave in New York City was significantly associated with differences in several dimensions of health care services use.

Project description:IntroductionOver 25,000 individuals are granted asylum status in the United States annually. Gender-based violence (GBV) has historically been supported as a claim for persecution to apply for asylum. In women, GBV is a known risk factor for sexually transmitted infections, poor mental health, and worse perinatal outcomes. Less is known about the links between GBV, asylum seekers, and gynecologic outcomes or care utilization. Reported rates of gynecologic care-seeking are low in asylum-seeking women and women with histories of GBV often experience barriers to care. We hypothesized that asylum-seeking women with a history of GBV at the Libertas Center, a comprehensive center for survivors of torture in New York City, would receive low rates of recommended gynecologic screening and infrequent gynecologic care.Materials and methodsThis retrospective cross-sectional study included adult self-identified female patients who had completed intake at the Libertas Center from 2005-2020. In order to examine the relationship between GBV and gynecologic care use, patients were included if they had an electronic medical record (EMR) at Elmhurst Hospital, were female, 18 years of age and older, and had ever experienced GBV in their lifetime. EMRs were reviewed for medical and psychiatric diagnoses as well as routine components of gynecologic care and were linked to intake data from the Libertas Center characterizing patients' torture history. The primary outcome of this study was whether or not patients attended a gynecology visit. Demographic characteristics, medical histories, adequacy of gynecologic care, and gynecologic care-seeking behavior were compared between the gynecologic care group and the no gynecologic care group.ResultsA total of 249 female patients were seen at the Libertas Center from December 2005 until January 2020 at the time of data collection. The prevalence of GBV in this population was 48%. Among women who suffered GBV, 81 received medical care at Elmhurst Hospital and 44 (54%) received gynecologic care. Nearly 50% of those patients who sought care at Elmhurst carried a diagnosis of post-traumatic stress disorder or depression. Women who received gynecologic care were significantly more likely than those who did not receive gynecologic care to have had an Emergency Room visit (68% vs. 41%), an obstetric visit (32% vs 3%), and/or have been seen by a social worker (46% vs 24%; all p < 0.05). Women who saw a gynecologist were significantly more likely to have completed four basic gynecologic care measures (Pap smear, gonorrhea/chlamydia screen, pelvic exam, and mammogram if applicable) compared to women who did not (77% vs 8%, p < 0.05).ConclusionThis study characterizes the gynecologic care utilization of female patients within a comprehensive care center for survivors of torture. We found a high lifetime rate of gender-based violence of 48% in this population. Adequate gynecologic care was uncommon among those who experienced GBV. However, gynecologic care was significantly more likely in patients receiving gynecologic specialty care, which frequently occurred after initial interaction with another provider (i.e. Emergency Department providers). These findings highlight the importance of trauma-informed care and establishing pathways to help asylum seeking and refugee women receive adequate gynecologic care. Further research is needed to explore specific barriers to gynecologic care in this population, how programs for asylum-seekers can integrate gynecologic care into existing structures for medical and mental healthcare, and how to increase awareness amongst providers on the prevalence of GBV and the gynecologic needs of these patients.

Project description:Importance:Internationally imported cases of measles into the United States can lead to outbreaks requiring extensive and rapid control measures. Importation of measles from an unvaccinated adolescent in 2013 led to what has been the largest outbreak of measles in New York City, New York, since 1992. Objective:To describe the epidemiology and public health burden in terms of resources and cost of the 2013 measles outbreak in New York City. Design, Setting, and Participants:This epidemiologic assessment and cost analysis conducted between August 15, 2013, and August 5, 2014, examined all outbreak-associated cases of measles among persons residing in New York City in 2013. Exposures:Measles virus. Main Outcomes and Measures:Numbers of measles cases and contacts. Total personnel time and total direct cost to the New York City Department of Health and Mental Hygiene (DOHMH), calculated as the sum of inputs (supplies and materials, equipment, and logistics) and personnel time (salary and fringe benefits). Results:Between March 13, 2013, and June 9, 2013, 58 persons in New York City with a median age of 3 years (range, 0-32 years) were identified as having measles. Among these individuals, 45 (78%) were at least 12 months old and were unvaccinated owing to parental refusal or intentional delay. Only 28 individuals (48%) visited a medical health care professional who suspected measles and reported the case to the DOHMH at the initial clinical suspicion. Many case patients were not immediately placed into airborne isolation, resulting in exposures in 11 health care facilities. In total, 3351 exposed contacts were identified. Total direct costs to the New York City DOHMH were $394?448, and a total of 10?054 hours were consumed responding to and controlling the outbreak. Conclusions and Relevance:Vaccine refusals and delays appeared to have propagated a large outbreak following importation of measles into the United States. Prompt recognition of measles along with rapid implementation of airborne isolation of individuals suspected of measles infection in health care facilities and timely reporting to public health agencies may avoid large numbers of exposures. The response and containment of measles outbreaks are resource intensive.
