Fragmentation Of Care

Background/Objective: Stroke patients may be unable to provide medical history. Given the urgency of decision-making in acute stroke and importance of medication compliance post-stroke, prompt access to prior health records could reduce delays and errors. We hypothesized that stroke patients often have fragmented care in the Chicago Health Atlas. Methods: The Chicago Health Atlas encompasses clinical data on over 1 million unique patients within the 606xx ZIP codes of Chicago. A unique ID is created for each patient through the use of a secure one-way hash function. The creation of a unique ID enables longitudinal tracking of a patient’s care across participating sites. We identified all acute stroke admissions to any of 4 Chicago Health Atlas hospitals using ICD-9 codes (430-436) and searched for prior inpatient or outpatient encounters at any of those sites. Fragmented care was defined as having prior encounters at a site different from the site of stroke hospitalization. In the same cohort, we assessed post-hospitalization outpatient encounters within the Health Atlas. Results: There were 5,980 stroke patients with emergency department or inpatient visits between 2006 and 2010. Of these, 3,732 (62.4%, mean age 61.1 years, 47% black) had non-fragmented care prior to stroke while 2,066 (34.5%, mean age 58.1 years, 31% black) were completely new encounters (first-ever) in the Health Atlas and only 182 (3.0%, mean age 57.5 years, 59% black) had fragmented care. The percent with fragmented care increased from 1.3% in 2006 to 3.3% in 2010 (p<0.001 for trend). Rates of follow-up within following 12 months varied across the 3 groups (non-fragmented: 75% and fragmented: 64% vs. new: 51.4%; p<0.001). Conclusions: Two-thirds of stroke patients have previously accessed the health care system, with a majority having records at the same site of stroke hospitalization. However, 3% of patients have fragmented care, a rate that is increasing over time. Our estimate of fragmentation may be an underestimate since only 4 sites were included in this analysis. Having health information exchange may be valuable in reducing fragmentation of care for stroke patients.

<b><i>Objective:</i></b> The frequency of seizures after stroke is high, with a severe impact on the quality of life. However, little is known about their prevention. Therefore, we investigated whether early administration of diazepam prevents the development of seizures in acute stroke patients. <b><i>Methods:</i></b> We performed a substudy of the EGASIS trial, a multicenter double-blind, randomized trial in which acute stroke patients were treated with diazepam or placebo for 3 days. Follow-up was after 2 weeks and 3 months. The occurrence of seizures was registered prospectively as one of the prespecified secondary outcomes. <b><i>Results:</i></b> 784 EGASIS patients were eligible for this substudy (389 treated with diazepam [49.6%] and 395 treated with placebo [50.4%]). Seizures were reported in 19 patients (2.4% of the total patient group). Seizures occurred less frequently in patients treated with diazepam (1.5 vs. 3.3% in the placebo group); however, this difference was only statistically significant in patients with a cortical anterior circulation infarction (0.9% in the diazepam group vs. 4.6% in the placebo group, incidence rate ratio 0.20, 95% CI: 0.05–0.78, <i>p</i> = 0.02, NNT = 27). <b><i>Conclusion:</i></b> We found that a 3-day treatment with diazepam after acute cortical anterior circulation stroke prevents the occurrence of seizures in the first 3 months following stroke.

PurposeThe region defined as ‘at risk’ penumbra by current CT perfusion (CTP) maps is largely overestimated. We aimed to quantitate the portion of true ‘at risk’ tissue within CTP penumbra and to determine the parameter and threshold that would optimally distinguish it from false ‘at risk’ tissue, that is, benign oligaemia.MethodsAmong acute stroke patients evaluated by multimodal CT (NCCT/CTA/CTP) we identified those that had not undergone endovascular/thrombolytic treatment and had follow-up NCCT. Maps of absolute and relative CBF, CBV, MTT, TTP and Tmax as well as summary maps depicting infarcted and penumbral regions were generated using the Intellispace Portal (Philips Healthcare, Best, Netherlands). Follow-up CT was automatically co-registered to the CTP scan and the final infarct region was manually outlined. Perfusion parameters were systematically analysed – the parameter that resulted in the highest true-negative-rate (ie, proportion of benign oligaemia correctly identified) at a fixed, clinically relevant false-negative-rate (ie, proportion of ‘missed’ infarct) of 15%, was chosen as optimal. It was then re-applied to the CTP data to produce corrected perfusion maps.ResultsForty seven acute stroke patients met selection criteria. Average portion of infarcted tissue within CTP penumbra was 15%±2.2%. Relative CBF at a threshold of 0.65 yielded the highest average true-negative-rate (48%), enabling reduction of the false ‘at risk’ penumbral region by ~half.ConclusionsApplying a relative CBF threshold on relative MTT-based CTP maps can significantly reduce false ‘at risk’ penumbra. This step may help to avoid unnecessary endovascular interventions.

Background: Sex differences may determine presentation, utility of treatment, rehabilitation, and occurrences of major adverse cardiovascular events (MACEs) in acute stroke (AS). Objective:The purpose of the study was to evaluate the short-term prognosis and long-term outcomes in MACEs in Qatari nationals admitted with AS. Methods: All AS patients admitted between January 2014 and February 2019 were included. We evaluated the preadmission modified Rankin scale (mRS) score, etiology and severity of symptoms, complications, and functional recovery at discharge and 90 days. MACEs were recorded for 5 years. Results: There were 891 admissions for AS (mean age 64.0 ± 14.2 years) (male, n = 519 [mean age ± SD 62.9 ± 14.1 years]; female, n = 372 [mean age ± SD 65.6 ± 14.2 years] p = 0.005). There were no differences in the preadmission mRS and severity of symptoms as measured on National Institute of Stroke Scale. At discharge, the outcome was better (mRS 0–2) in men (57.8 vs. 46.0%), p = 0.0001. This difference persisted at the 90-day follow-up (mRS 0–2, male 69.4% vs. female 53.2%, p = 0.0001). At the 90-day follow-up, more women died (total deaths 70; women 38 [10.2%] versus men 32 [6.2%], p = 0.03). MACEs occurred in 25.6% (133/519) males and 30.9% (115/372) females over the 5-year follow-up period (odds ratio 0.77, 95% confidence interval 0.57–1.0, p = 0.83). Conclusions: Female patients have a poor short-term outcome following an AS when corrected for age and comorbidities. While our study cannot explain the reasons for the discrepancies, higher poststroke depression and social isolation in women may be important contributory factors, and requires further studies are required to confirm these findings.

Summary Objective: The field of clinical informatics has expanded substantially in the six decades since its inception. Early research focused on simple demonstrations that health information technology (HIT) such as electronic health records (EHRs), computerized provider order entry (CPOE), and clinical decision support (CDS) systems were feasible and potentially beneficial in clinical practice. Methods: In this review, we present recent evidence on clinical informatics in the United States covering three themes: 1) clinical informatics systems and interventions for providers, including EHRs, CPOE, CDS, and health information exchange; 2) consumer health informatics systems, including personal health records and web-based and mobile HIT; and 3) methods and governance for clinical informatics, including EHR usability; data mining, text mining, natural language processing, privacy, and security. Results: Substantial progress has been made in demonstrating that various clinical informatics methodologies and applications improve the structure, process, and outcomes of various facets of the healthcare system. Conclusion: Over the coming years, much more will be expected from the field. As we move past the “early adopters” in Rogers' diffusion of innovations' curve through the “early majority” and into the “late majority,” there will be a crucial need for new research methodologies and clinical applications that have been rigorously demonstrated to work (i.e., to improve health outcomes) in multiple settings with different types of patients and clinicians.

Blockchain could reinvent the way patient’s electronic health records are shared and stored by providing safer mechanisms for health information exchange of medical data in the healthcare industry, by securing it over a decentralized peer-to-peer network. Intending to support and ease the understanding of this distributed ledger technology, a solid Systematic Literature Review was conducted, aiming to explore the recent literature on Blockchain and healthcare domain and identify existing challenges and open questions, guided by the raise of research questions regarding EHR in a Blockchain. More than 300 scientific studies published in the last ten years were surveyed, resulting in an up-to-date taxonomy creation, challenges and open questions identified, and the most significant approaches, data types, standards and architectures regarding the use of Blockchain for EHR were assessed and discussed.
