Background and Purpose-The characteristics of intracerebral hemorrhage (ICH) may vary by ICH location because of differences in the distribution of underlying cerebral small vessel diseases. Therefore, we investigated the incidence, characteristics, and outcome of lobar and nonlobar ICH. Methods-In a population-based, prospective inception cohort study of ICH, we used multiple overlapping sources of case ascertainment and follow-up to identify and validate ICH diagnoses in 2010 to 2011 in an adult population of 695 335. Results-There were 128 participants with first-ever primary ICH. The overall incidence of lobar ICH was similar to nonlobar ICH (9.

National Institute for Health and Clinical Excellence guidelines recommend the use of 'Track and Trigger' systems to identify early clinical deterioration. The Standardised Early Warning Score (SEWS) is used in the Royal Infirmary of Edinburgh. Previous work, suggested that the frequency and accuracy of SEWS documentation varied throughout the hospital. A prospective study was performed over a 14-night period looking at SEWS documentation in patients causing clinical concern requiring medical review, or triggering a SEWS of 4 (the 'trigger' score). SEWS charts were examined the following morning. In the ward arc, SEWS documentation was correct in only 21% of cases. The most frequent errors were one or more observations omitted (64%), SEWS total not calculated (55%) or incorrectly calculated (21%). Up to five errors per chart were noted. The observations most frequently omitted were respiratory rate, temperature and neurological status. In contrast, SEWS documentation was correct in 68% of patients in the combined assessment unit (CAU). This study demonstrates significant deficiencies in the overnight use of SEWS, particularly on the ward arc. This is particularly concerning as this study was limited only to patients already causing clinical concern, and highlights that basic observations are often incomplete, and the SEWS chart poorly understood and acted upon. SEWS recording and documentation was significantly better in CAU (P < 0.001, FET), where there is a dedicated, ongoing SEWS education programme for nursing and medical staff. We recommend this is rolled out across the hospital. Alternative methods of improving the use of SEWS are considered.

Background Hospital-based studies have reported variable associations between outcome after spontaneous intracerebral hemorrhage and peri-hematomal edema volume. Aims In a community-based study, we aimed to investigate the existence, strength, direction, and independence of associations between intracerebral hemorrhage and peri-hematomal edema volumes on diagnostic brain CT and one-year functional outcome and long-term survival. Methods We identified all adults, resident in Lothian, diagnosed with first-ever, symptomatic spontaneous intracerebral hemorrhage between June 2010 and May 2013 in a community-based, prospective inception cohort study. We defined regions of interest manually and used a semi-automated approach to measure intracerebral hemorrhage volume, peri-hematomal edema volume, and the sum of these measurements (total lesion volume) on first diagnostic brain CT performed at ≤3 days after symptom onset. The primary outcome was death or dependence (scores 3–6 on the modified Rankin Scale) at one-year after intracerebral hemorrhage. Results Two hundred ninety-two (85%) of 342 patients (median age 77.5 y, IQR 68–83, 186 (54%) female, median time from onset to CT 6.5 h (IQR 2.9–21.7)) were dead or dependent one year after intracerebral hemorrhage. Peri-hematomal edema and intracerebral hemorrhage volumes were colinear ( R2 = 0.77). In models using both intracerebral hemorrhage and peri-hematomal edema, 10 mL increments in intracerebral hemorrhage (adjusted odds ratio (aOR) 1.72 (95% CI 1.08–2.87); p = 0.029) but not peri-hematomal edema volume (aOR 0.92 (0.63–1.45); p = 0.69) were independently associated with one-year death or dependence. 10 mL increments in total lesion volume were independently associated with one-year death or dependence (aOR 1.24 (1.11–1.42); p = 0.0004). Conclusion Total volume of intracerebral hemorrhage and peri-hematomal edema, and intracerebral hemorrhage volume alone on diagnostic brain CT, undertaken at three days or sooner, are independently associated with death or dependence one-year after intracerebral hemorrhage, but peri-hematomal edema volume is not.

This is the first study that we are aware of directly comparing out-of-hours performance before and after the implementation of H@N. Significant improvements in both patient and system outcomes were observed, with no adverse effects noted.
