Introduction: Intraventricular hemorrhage (IVH) occurs in about 40% of patients with intracerebral hemorrhage (ICH) and is associated with higher mortality and worse outcomes than ICH patients without IVH. Infections are common in ICH patients but data in IVH patients are limited. Methods: Prospective analysis of adjudicated adverse event infection reporting during first 180 days in 500 patients enrolled in the CLEAR III trial, a multicenter, double-blind, randomized study comparing external ventricular drain (EVD) + intraventricular recombinant tissue plasminogen activator (rtPA) vs. EVD + placebo for treatment of obstructive IVH and intracerebral hemorrhage (ICH) volume <30cc. Primary outcome measures were 90-day and 180-day mortality. Secondary outcome measures were hospital length of stay (LOS). We constructed binary logistic and linear regression models for multivariable analysis. Results: Infection was reported in 269 patients (53.8%). Pneumonia was the most common infection (33%), followed by UTI (16%), and bacterial ventriculitis (4.4%). Overall 180-day mortality was 20%. Patients with infection were more likely to have older age (p=0.012), lower admission GCS (p=0.007), higher ICH volume (8.8 vs 6.7ml, p=0.001), and higher ICH+IVH volume (37.7 vs 31.7 ml, p=0.002). In the regression model, IVH volume was associated with higher odds of 90-day or 180-day mortality, but presence of any infection was not a significant predictor of mortality. Infection was however associated with longer length of stay (26 vs 22 days, p<0.001). Subgroup analysis of individual infections, showed only bacterial ventriculitis to be associated with 90-day (OR: 3.84, CI: 1.36-10.82), and 180-day mortality (OR: 2.9, CI: 1.05-8.06), while pneumonia and UTI were not. Conclusion: Patients with IVH have a high incidence of infections, which is associated with longer hospitalization but does not appear to influence mortality. Of the infections, bacterial ventriculitis is a significant predictor of mortality in our 7-factor model. IVH volume did not predict infections but predicted mortality.These results form a basis for future correlation of infectious complications with treatment rendered (thrombolysis versus placebo), with upcoming unblinding of the trial.

Introduction: Intraventricular hemorrhage (IVH) occurs in about 40% of patients with intracerebral hemorrhage (ICH) and is associated with higher mortality and worse outcomes than ICH patients without IVH. Venous thromboembolism (VTE) is common in ICH patients but data in IVH patients are limited. Methods: Prospective analysis of adjudicated adverse event reporting of VTE (deep venous thrombosis (DVT) and pulmonary embolism (PE)) during first 180 days in 500 patients enrolled in the CLEAR III trial, a multicenter, double-blind, randomized study comparing external ventricular drain (EVD) + intraventricular recombinant tissue plasminogen activator (rtPA) vs EVD + placebo for treatment of obstructive IVH and intracerebral hemorrhage (ICH) volume <30cc. Outcome measures were 90-day and 180-day mortality, ICU and hospital length of stay (LOS), catheter tract hemorrhage as well as predictors of VTE. Results: VTE was reported in 63 patients (13%); 46 (9%), 11 (2%) and 6 (1%) patients had DVT, PE or both, respectively. VTE occurred between 4 and 209 days from ICH onset. VTE pharmacologic prophylaxis was initiated in 404 (81%) patients, at median of 4 days [range:1-48] from ICH onset. Unfractionated and low molecular weight heparin were used in 71% and 29% patients, respectively. These patients had similar rates of VTE but showed a trend towards higher catheter tract hemorrhages (25 vs 15%, p=0.056) as compared to those who did not receive VTE prophylaxis. Patients who developed VTE had similar 90-d and 180-d mortality and ICU LOS but had prolonged hospital LOS (p=0.012) as compared to those who did not develop VTE. On multivariable analysis, ICH volume was a significant predictor of development of VTE (OR 1.04, 95% CI: 1.01-1.07, p=0.024). Conclusions: The association of IVH with VTE is important but complex, in spite of consideration of early VTE prophylaxis. There was trend towards higher catheter tract hemorrhages in patients receiving VTE prophylaxis. ICH volume was a significant predictor of VTE development. However, mortality and ICU LOS were not affected by VTE development. These results form a basis for future correlation of VTE complications with treatment rendered (thrombolysis versus placebo), with upcoming unblinding of the trial.

Csf Drainage

Background: Acute obstructive hydrocephalus secondary to spontaneous intracerebral/intraventricular hemorrhage (ICH/IVH) requires early cerebrospinal fluid (CSF) drainage to reduce intracranial pressure (ICP). Extensive CSF drainage may reduce IVH clot burden. We characterize CSF dynamics, strategies and impact on end of treatment (EOT) IVH volume (72 hours post randomization [Rand]) in the CLEAR III trial. Methods: Prospective analysis of CSF output in all 500 patients enrolled in the CLEAR III trial, a multicenter, double-blind, randomized study comparing EVD + intraventricular recombinant tissue plasminogen activator (rtPA) vs. EVD + placebo for treatment of obstructive IVH and intracerebral hemorrhage (ICH) volume <30cc. CSF output was recorded every 4 hours until 7 days post Rand, and compared by clinical and radiological variables. Results: Daily median CSF output in the first week was 188cc (IQR: 125, 252). Maximum daily EVD drip settings were <10mmHg in 27.8%, =10 in 44.1% and >10 in 28.1%. Independent predictors of higher daily CSF output after adjustment for initial IVH volume (p=0.04) were lower drip setting (p<0.001), lower age (p<0.001), male sex (p=0.03), dual EVD (p=0.005), CSF protein (p<0.001) and ICP>20mmHg (P=0.007). Both EOT IVH volume and change in IVH volume (ChgIVH) (over 1 st week) were independently associated with total CSF output (P=0.004/<0.001, respectively), and initial IVH volume (P<0.001/<0.001)). Early opening of 3 rd and 4 th ventricle (P=0.03) was associated with lower EOT volumes, while CSF protein (P=0.02), and side of EVD ipsilateral to largest IVH (P=0.04) were associated with ChgIVH. Shunting for hydrocephalus was performed in 18.6% over 1 year follow-up and was associated with higher total CSF output over first week (P<0.001). Conclusions: CSF circulation in severe IVH can be assessed by CSF output which is associated with EVD drip management and other clinical variables. EOT IVH volume and IVH volume reduction are important surrogate endpoints which are related to CSF dynamics. VP shunt requirement in spontaneous IVH is associated with early CSF output levels. These results permit future correlation of CSF output with treatment rendered (thrombolysis versus placebo) with upcoming unblinding of the trial.

The Impact

Background and Objective: Intraventricular hemorrhage (IVH) is a verified independent prognostic parameter in patients with intracerebral hemorrhage (ICH). However, the impact of the extent of IVH on clinical outcomes is unestablished. Methods: We analyzed 1,112 consecutive primary ICH patients of the UKER-ICH cohort (NCT03183167) and hypothesized that there is no difference in outcome between patients without IVH and patients with minor IVH not leading to obstructive hydrocephalus. Propensity score matching and multivariable analyses were performed to account for imbalances in baseline characteristics. Primary outcome was defined as functional outcome 3 months after ICH ­assessed using the modified Rankin Scale (mRS) dichotomized into favorable (mRS = 0–3) and unfavorable outcome (mRS = 4–6). Secondary outcomes included mortality at 3  months and a Graeb score-based threshold analysis for association of the extent of IVH with unfavorable clinical outcome. Results: Among the 461 out of 1,112 (41.5%) ICH patients with IVH, 191 out of 461 (41.4%) showed IVH without obstructive hydrocephalus and no requirement of external ventricular drain (EVD) placement. After adjusting for baseline imbalances we found no difference in functional outcome at 3 months between patients without IVH (No-IVH) and patients with IVH not requiring EVD (IVH-w/o-EVD): mRS 0–3: No-IVH 64/161 (39.8%) vs. IVH-w/o-EVD 53/170 (31.2%); p = 0.103. However, there was a trend toward a higher mortality in IVH-w/o-EVD patients (mRS 6: No IVH 40/161 [24.8%] vs. IVH-w/o-EVD 57/170 [33.5%]; p = 0.083). Multivariable analysis revealed that a Graeb score >2 was independently associated with unfavorable outcome (mRS 4–6: OR 3.16 [1.54–6.48]; p = 0.002), and higher mortality (mRS 6: OR 2.57 [1.40–4.74]; p = 0.002) in IVH patients. Conclusions: Small amounts of intraventricular blood (Graeb score ≤2) not leading to obstructive hydrocephalus are not associated with unfavorable outcome or death after ICH. Thus, IVH per se should not be considered a binary variable in outcome prediction for ICH patients.

e18038 Background: Patients with head and neck cancer carry the prospect of facial disfigurement in addition to the effects on speech, smell, sight, and taste. As such they are at a higher risk of acquiring emotional distress. Despite this, depression is underreported in this population. We review the National Inpatient Sample (NIS) to understand the effects of depression in patients admitted with any diagnosis of head and neck cancer. Methods: We designed a retrospective study and utilized NIS data for the year 2018. We identified patients with any history of Head and Neck cancer using their specific ICD-10 codes. We also identified codes for depressive disorders. Primary outcome was effect of depression on comorbidities. Secondary outcome was hospital length of stay. Utilizing STATA MP 16.1 we performed multivariate logistic regression analysis. Various comorbidities including previous history of coronary artery disease, congestive heart failure, stroke, smoking, hyperlipidemia, and chemotherapy were incorporated into the analysis. Results: The study population included 15,689 patients that were 18 years or older. Mean age was 64 years. Only 28% of the population was females. The mean hospital length of stay was approximately 7 days. In this group of patients, 12% had a history of depression. Among the different types of head and neck cancers oropharyngeal cancers had the highest percentage of depression rates (14%). In multivariable analysis, patients with depression had a higher comorbidity index but this result did not reach statistical significance (Odds Ratio (OR) 1.02, p = 0.054, 95% Confidence Intervals (CI) 0.999 – 1.045). Patients had higher odds of having depression if they also had a history of stroke (OR 1.4, 95% CI 1.13 – 1.73), prior history of chemotherapy (OR 1.25, 95% CI 1.09 – 1.43), history of hyperlipidemia (OR 1.31, 95% CI 1.16 – 1.48) or were admitted over the weekend (OR 1.21, 95% CI 1.07 – 1.38). Younger age was associated with lower odds of depression (OR 0.98, 95% CI 0.98 – 0.99). Women had higher odds of having depression (OR 1.68, 95% CI 1.51 – 1.88). When compared with white people, people from the following demographics had lower odds of depression – Black (OR 0.56, 95% CI 0.47 – 0.68), Hispanic (OR 0.64, 95% CI 0.49 – 0.83), Asian (OR 0.26, 95% CI 0.17 – 0.43), and others (OR 0.53, 95% CI 0.35 – 0.79). Hospital length of stay was higher among patients with depression (OR 0.7, 95% CI 0.2 – 1.15). Conclusions: Among patients with head and neck cancer, odds of having depression are higher in the white population, older patients, females and patients with prior history of chemotherapy. Depression is associated with higher hospital length of stay. These findings help understand the effect of depression on this susceptible population and identify at risk patients for appropriate screening.

ObjectivesThis study aimed to examine the prevalence and distribution in the comorbidity of non-communicable diseases (NCDs) among the adult population in Bangladesh by measures of socioeconomic status (SES).DesignThis was a cross-sectional study.SettingThis study used Bangladesh Demographic and Health Survey 2011 data.ParticipantsTotal 8763 individuals aged ≥35 years were included.Primary and secondary outcome measuresThe primary outcome measures were diabetes mellitus (DM), hypertension (HTN) and overweight/obesity. The study further assesses factors (in particular SES) associated with these comorbidities (DM, HTN and overweight/obesity).ResultsOf 8763 adults,12% had DM, 27% HTN and 22% were overweight/obese (body mass index ≥23 kg/m2). Just over 1% of the sample had all three conditions, 3% had both DM and HTN, 3% DM and overweight/obesity and 7% HTN and overweight/obesity. DM, HTN and overweight/obesity were more prevalent those who had higher education, were non-manual workers, were in the richer to richest SES and lived in urban settings. Individuals in higher SES groups were also more likely to suffer from comorbidities. In the multivariable analysis, it was found that individual belonging to the richest wealth quintile had the highest odds of having HTN (adjusted OR (AOR) 1.49, 95% CI 1.29 to 1.72), DM (AOR 1.63, 95% CI 1.25 to 2.14) and overweight/obesity (AOR 4.3, 95% CI 3.32 to 5.57).ConclusionsIn contrast to more affluent countries, individuals with NCDs risk factors and comorbidities are more common in higher SES individuals. Public health approaches must consider this social patterning in tackling NCDs in the country.

Purpose: Hypophosphatemia is reported in up to 5% of hospitalized patients and ranges from 20% to 80% in critically ill patients. The consequences of hypophosphatemia for critically ill patients remain controversial. We evaluated the effect of hypophosphatemia on mortality and length of stay in intensive care unit (ICU) patients. Methods: MEDLINE, EMBASE, Cochrane Library (Reviews and Trials), and PubMed were searched for articles in English. The primary outcome was mortality and secondary outcome was length of stay. The quality of evidence was graded using a modified Newcastle-Ottawa Scale. Results: Our search yielded 828 articles and ultimately included 12 studies with 7626 participants in the analysis. Hypophosphatemia was associated with increased hospital length of stay (2.19 days [95% CI, 1.74-2.64]) and ICU length of stay (2.22 days [95% CI, 1.00-3.44]) but not mortality (risk ratio: 1.13 [95% CI, 0.98-1.31]; P = .09). Conclusions: Hypophosphatemia in ICU was associated with increased hospital and ICU length of stay but not all-cause mortality. Hypophosphatemia appears to be a marker of disease severity. Limited number of available studies and varied study designs did not allow for the ascertainment of the effect of severe hypophosphatemia on patient mortality.

Abstract Background: Acute kidney injury is a common complication following the Norwood operation. Most neonatal studies report acute kidney injury peaking within the first 48 hours after cardiac surgery. The aim of this study was to evaluate if persistent acute kidney injury (>48 postoperative hours) after the Norwood operation was associated with clinically relevant outcomes. Methods: Two-centre retrospective study among neonates undergoing the Norwood operation. Acute kidney injury was initially identified as developing within the first 48 hours after cardiac surgery and stratified into transient (≤48 hours) and persistent (>48 hours) using the neonatal modification of the Kidney Disease: Improving Global Outcomes serum creatinine criteria. Severe was defined as stage ≥2. Primary and secondary outcomes were mortality and duration of ventilation and hospital length of stay. Results: One hundred sixty-eight patients were included. Transient and persistent acute kidney injuries occurred in 24 and 17%, respectively. Cardiopulmonary bypass and aortic cross clamp duration, and incidence of cardiac arrest were greater among those with persistent kidney injury. Mortality was four times higher (41 versus 12%, p < 0.001) and mechanical ventilation duration 50 hours longer in persistent acute kidney injury patients (158 versus 107 hours; p < 0.001). In multivariable analysis, persistent acute kidney injury was not associated with mortality, duration of ventilation or length of stay. Severe persistent acute kidney injury was associated with a 59% increase in expected ventilation duration (aIRR:1.59, 95% CI:1.16, 2.18; p = 0.004). Conclusions: Future large studies are needed to determine if risk factors and outcomes change by delineating acute kidney injury into discrete timing phenotypes.

ObjectivesTo determine whether stroke patients’ acute hospital length of stay (AHLOS) varies between hospitals, over and above case mix differences and to investigate the hospital-level explanatory factors.DesignA multicentre prospective cohort study.SettingEight National Health Service acute hospital trusts within the Anglia Stroke & Heart Clinical Network in the East of England, UK.ParticipantsThe study sample was systematically selected to include all consecutive patients admitted within a month to any of the eight hospitals, diagnosed with stroke by an accredited stroke physician every third month between October 2009 and September 2011.Primary and secondary outcome measuresAHLOS was defined as the number of days between date of hospital admission and discharge or death, whichever came first. We used a multiple linear regression model to investigate the association between hospital (as a fixed-effect) and AHLOS, adjusting for several important patient covariates, such as age, sex, stroke type, modified Rankin Scale score (mRS), comorbidities and inpatient complications. Exploratory data analysis was used to examine the hospital-level characteristics which may contribute to variance between hospitals. These included hospital type, stroke monthly case volume, service provisions (ie, onsite rehabilitation) and staffing levels.ResultsA total of 2233 stroke admissions (52% female, median age (IQR) 79 (70 to 86) years, 83% ischaemic stroke) were included. The overall median AHLOS (IQR) was 9 (4 to 21) days. After adjusting for patient covariates, AHLOS still differed significantly between hospitals (p<0.001). Furthermore, hospitals with the longest adjusted AHLOS’s had predominantly smaller stroke volumes.ConclusionsWe have clearly demonstrated that AHLOS varies between different hospitals, and that the most important patient-level explanatory variables are discharge mRS, dementia and inpatient complications. We highlight the potential importance of stroke volume in influencing these differences but cannot discount the potential effect of unmeasured confounders.

Background: Non-specific low back pain (LBP) is a common health problem resulting from many risk factors and human behaviors. Some of thesemay interact synergistically and have been implicated in the cause of low back pain. Massage both traditional Thai massage and joint mobilization as a common practice has been shown to be effective for some subgroup of nonspecific LBP patients.Purpose and Setting: The trial compared the effectiveness between traditional Thai massage and joint mobilization for treating nonspecificLBP. Some associated factors were included. The study was conducted at the orthopedic outpatient department, Lerdsin General Hospital, Bangkok, Thailand.Methods: Prospective, randomized study was developed without control group. The required sample size was estimated based on previouscomparative studies for effectiveness between techniques. Two primary outcome measures were a 0 to 10 visual analog scale (VAS) of pain andOswestry Disability Index (ODI). Secondary outcome measures were satisfaction of patients and adverse effects of the treatment. The ‘‘intention to treat’’ (ITT) and per protocol approach were used to compare the significance of the difference between treatment groups.Participants: One hundred and twenty hospital outpatients, 20 (16.7%) male and 100 (83.3%) female, were randomized into traditional Thai massage and joint mobilization therapy. The average age of traditional Thai massage and joint mobilization was 50.7 years and 48.3 years, respectively. Both groups received each treatment for approximately 30 minutes twice per week over a four-week period. Total course did not exceed eight sessions.Result: With ITT, the mean VAS of traditional Thai massage group before treatment was 5.3 (SD = 1.7) and ODI was 24.9 (SD = 14.7), while in jointmobilization groups, the mean VAS was 5.0 (SD = 1.6) and ODI was 24.6 (SD = 15). After treatment, the mean VAS and ODI were significantlyreduced (VAS = 0.51 (SD = 0.89) and ODI = 8.1 (SD = 10.7) for traditional Thai massage, VAS = 0.86 (SD = 1.49) and ODI = 8.26 (SD = 12.97) for joint mobilization). Constipation was found in 34 patients (28.3%).Conclusion: The traditional Thai massage and joint mobilization used in this study were equally effective for short-term reduction of pain and disability in patients with chronic nonspecific LBP. Both techniques were safe with short term effect in a chosen group of patients.
