This prospective quasi-experimental study from the NASAM (National Approach to Standardize and Improve Mechanical Ventilation) collaborative assessed the impact of evidence-based practices including subglottic suctioning, daily assessment for spontaneous awakening trial (SAT), spontaneous breathing trial (SBT), head of bed elevation, and avoidance of neuromuscular blockers unless otherwise indicated. The study outcomes included VAE (primary) and intensive care unit (ICU) mortality. Changes in daily care process measures and outcomes were evaluated using repeated measures mixed modeling. The results were reported as incident rate ratio (IRR) for each additional month with 95% confidence interval (CI). A comprehensive program that included education on evidence-based practices for optimal care of mechanically ventilated patients with real-time benchmarking of daily care process measures to drive improvement in forty-two ICUs from 26 hospitals in Saudi Arabia (>27,000 days of observation). Compliance with subglottic suctioning, SAT and SBT increased monthly during the project by 3.5%, 2.1% and 1.9%, respectively (IRR 1.035, 95%CI 1.007–1.064, p = 0.0148; 1.021, 95% CI 1.010–1.032, p = 0.0003; and 1.019, 95%CI 1.009–1.029, p = 0.0001, respectively). The use of neuromuscular blockers decreased monthly by 2.5% (IRR 0.975, 95%CI 0.953–0.998, p = 0.0341). The compliance with head of bed elevation was high at baseline and did not change over time. Based on data for 83153 ventilator days, VAE rate was 15.2/1000 ventilator day (95%CI 12.6–18.1) at baseline and did not change during the project (IRR 1.019, 95%CI 0.985–1.053, p = 0.2812). Based on data for 8523 patients; the mortality was 30.4% (95%CI 27.4–33.6) at baseline, and decreased monthly during the project by 1.6% (IRR 0.984, 95%CI 0.973–0.996, p = 0.0067). A national quality improvement collaborative was associated with improvements in daily care processes. These changes were associated with a reduction in mortality but not VAEs. Registration The study is registered in clinicaltrials.gov (NCT03790150).

Abstract Background To evaluate the effect of screening for sepsis using an electronic sepsis alert vs. no alert in hospitalized ward patients on 90-day in-hospital mortality. Methods The SCREEN trial is designed as a stepped-wedge cluster randomized controlled trial. Hospital wards (total of 45 wards, constituting clusters in this design) are randomized to have active alert vs. masked alert, 5 wards at a time, with each 5 wards constituting a sequence. The study consists of ten 2-month periods with a phased introduction of the intervention. In the first period, all wards have a masked alert for 2 months. Afterwards the intervention (alert system) is implemented in a new sequence every 2-month period until the intervention is implemented in all sequences. The intervention includes the implementation of an electronic alert system developed in the hospital electronic medical records based on the quick sequential organ failure assessment (qSOFA). The alert system sends notifications of “possible sepsis alert” to the bedside nurse, charge nurse, and primary medical team and requires an acknowledgment in the health information system from the bedside nurse and physician. The calculated sample size is 65,250. The primary endpoint is in-hospital mortality by 90 days. Discussion The trial started on October 1, 2019, and is expected to complete patient follow-up by the end of October 2021. Trial registration ClinicalTrials.gov NCT04078594 .

Abstract In countries where headache services exist at all, their focus is usually on specialist (tertiary) care. This is clinically and economically inappropriate: most headache disorders can effectively and more efficiently (and at lower cost) be treated in educationally supported primary care. At the same time, compartmentalizing divisions between primary, secondary and tertiary care in many health-care systems create multiple inefficiencies, confronting patients attempting to navigate these levels (the “patient journey”) with perplexing obstacles. High demand for headache care, estimated here in a needs-assessment exercise, is the biggest of the challenges to reform. It is also the principal reason why reform is necessary. The structured headache services model presented here by experts from all world regions on behalf of the Global Campaign against Headache is the suggested health-care solution to headache. It develops and refines previous proposals, responding to the challenge of high demand by basing headache services in primary care, with two supporting arguments. First, only primary care can deliver headache services equitably to the large numbers of people needing it. Second, with educational supports, they can do so effectively to most of these people. The model calls for vertical integration between care levels (primary, secondary and tertiary), and protection of the more advanced levels for the minority of patients who need them. At the same time, it is amenable to horizontal integration with other care services. It is adaptable according to the broader national or regional health services in which headache services should be embedded. It is, according to evidence and argument presented, an efficient and cost-effective model, but these are claims to be tested in formal economic analyses.

ObjectivesTo study the clinical characteristics and outcomes of patients experiencing an ischemic stroke during Ramadan vs. non-Ramadan months in a tertiary academic center in an Islamic country.MethodsWe retrospectively reviewed all patients with ischemic stroke (IS) in Ramadan and non-Ramadan months for four consecutive years (February 2016–June 2019). All demographics, vascular risk factors, laboratory results, modified Rankin Scale (mRS) at admission and discharge, National Institute Stroke Scale (NIHSS), and in-hospital complication data were collected for all patients.ResultsOne thousand and 58 patients were included (non-Ramadan, n = 960; during Ramadan, n = 98). The mean age during Ramadan was 59 ± 13 years. Most non-Ramadan IS patients during Ramadan were male (68.5%; 57.1%, respectively). There was no statistical difference in vascular risk factors and medical history between the two groups. However, Ramadan patients had higher median NIHSS scores at discharge (p = 0.0045). In addition, more ICU admissions were noted among Ramadan patients (p = 0.009). In the gender-specific analysis for Ramadan patients, we found a statistically significant difference in smoking and urinary tract infection (p = 0.006, p = 0.005, respectively).ConclusionBased on our results, there was no difference, in general, between patients with IS during Ramadan and non-Ramadan months. However, IS patients had higher NIHSS scores at discharge and more ICU admissions during Ramadan. Last, we suggest future studies with larger sample sizes, longer duration, and including all types of strokes.

Abstract Background The large geographical gaps in our knowledge of the prevalence and burden of headache disorders include most of Eastern Mediterranean Region (EMR). Following a nationwide population-based study in Pakistan, we present here a similar study from Kingdom of Saudi Arabia (KSA). Both were conducted as projects within the Global Campaign against Headache The two purposes of this study were to inform national health policy and contribute to global knowledge of headache disorders. Methods We surveyed Arabic-speaking adults aged 18–65 years in all 13 regions of KSA. While previous Global Campaign studies have engaged participants by calling at randomly selected households, the culture of KSA made this unacceptable. Participants were, instead, contacted by cell-phone (since cell-phone coverage exceeded 100% in KSA), using random-digit dialling. Trained interviewers used a culturally adapted version of the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire, with diagnostic enquiry based on ICHD-II. We estimated 1-year prevalences of the headache disorders of public-health importance (migraine, tension-type headache [TTH] and probable medication-overuse headache [pMOH]) and examined their associations with demographic variables. Results A total of 2316 participants (mean age of 32.2 ± 10.7 years; 62.3% male; 37.7% female) were included (participation proportion 86.5%). Gender and age distributions imperfectly matched those of the national population, requiring adjustments for these to prevalence estimates. Observed 1-year prevalence of all headache was 77.2%, reducing to 65.8% when adjusted. For headache types, adjusted 1-year prevalences were migraine 25.0%, TTH 34.1%, pMOH 2.0% and other headache on ≥15 days/month 2.3%. Adjusted 1-day prevalence of any headache was 11.5%. Migraine and pMOH were associated with female gender (ORs: 1.7 and 4.7; p 45 years (OR: 0.4; p = 0.0143) while pMOH was most prevalent in those aged 46–55 years (OR: 2.7; p = 0.0415). TTH reportedly became more common with increasing level of education. Conclusion Prevalences of migraine and TTH in KSA are considerably higher than global averages (which may be underestimated), and not very different from those in Pakistan. There is more pMOH in KSA than in Pakistan, reflecting, probably, its higher-income status and greater urbanisation (facilitating access to medication).

Background: Stroke is a medical condition that leads to major disability and mortality worldwide. Some evidence suggests that weather and seasonal variations could have an impact on stroke incidence and outcome. However, the current evidence is inconclusive. Therefore, this study examines the seasonal variations and meteorological influences on stroke incidence and outcome in the largest city in Saudi Arabia.Methods: From February 2016 to July 2019, we retrospectively reviewed data from all patients with acute ischemic (AIS) or hemorrhagic stroke (HS) admitted to the stroke unit in a tertiary academic center in Saudi Arabia. The corresponding daily meteorological data were obtained for the same period. We considered the months from November to March as the cold season and April to October as the hot season.Results: The final cohort included 1,271 stroke patients; 60.89% (n = 774) cases occurred in the hot season, while 39.1% (n = 497) in the cold season. Males accounted for 69.6% (n = 884) of the cases. The proportion of ischemic stroke was 83.2% [hot season 83.9% (n = 649) vs. cold season 82.3% (n = 409)]. We found no statistically significant difference between seasons (hot or cold) in stroke incidence, severity [National Institutes of Health Stroke Scale (NIHSS)], hospital course (pneumonia, thromboembolism, intensive care stay, or length of stay), or outcome [modified Rankin scale (mRS) on discharge and death].Conclusions: In Riyadh, Saudi Arabia, our study found no impact of weather or seasonal variations on stroke incidence, hospital course, or outcomes. However, our findings warrant further research in different country regions.

Lacunar stroke (LS) is responsible for one-quarter of the overall number of ischemic strokes with long-term complications and carries health and economic issues for patients and health care systems. Therefore, we aimed to investigate lacunar versus non-lacunar strokes in a tertiary academic center. From February 2016 to July 2019, all patients admitted to the stroke unit were retrospectively reviewed. We included LS patients and compared them to other TOAST subtypes. Hemorrhagic stroke and conditions mimicking stroke were excluded. Regression analysis was done to determine LS predictors and outcomes. A 35.5% rate of LS among 989 ischemic stroke patients was found. Most patients (71.9%) were males. Lower National Institutes of Health Stroke Scale (NIHSS) scores at admission and negative history for cardiac diseases were predictors for LS in our population. At discharge, LS patients had low NIHSS scores and shorter hospitalization periods compared to non-LS patients. In conclusion, LS was prevalent among ischemic stroke patients in our cohort. Future studies are highly needed with long follow-up intervals to identify the stroke recurrence, complications, and outcomes.

Introduction. Embolic stroke of undetermined source (ESUS) in younger adults may have different risk factors compared with ESUS in elderly, and the approach to ESUS in young adults may require new therapies. We aimed to investigate the characteristics and outcomes in younger adults with ESUS at a single centre in Saudi Arabia. Patients and Methods. A retrospective study was conducted using the medical records of younger adults with ESUS according to the criteria of the Cryptogenic Stroke/ESUS International Working Group. Younger adults (aged ≤50 years) with ESUS were compared with older patients, on admission and discharge from hospital, using the modified Rankin scale (mRS) and the National Institute of Health Stroke Scale (NIHSS). Results. Among 147 patients with ESUS, 39 (26.5%) were younger adults. Younger adults compared with older adults with ESUS had fewer vascular risk factors, including lower rates of hypertension (43.6% vs. 70.3%; P=0.004), diabetes (35.9% vs. 57.4%; P=0.03), and dyslipidaemia (12.8% vs. 28.7%; P=0.05). There was no significant difference in poor outcome at discharge (defined as mRS > 2), which was observed in 17.9% of younger adults and 28.7% of older adults. Further, there were no significant differences in stroke severity at discharge (NIHSS score ≤5) or median length of stay. Discussion. Although the outcomes of ESUS do not differ between younger and older patients, younger patients have fewer identified risk factors. Conclusion. This study showed that 26.5% of patients with ESUS were aged ≤50 years. Although younger adults with ESUS had fewer risk factors, there were no significant differences in neurologic disability or mortality at discharge, stroke severity, or median length of stay.

Background: Tissue plasminogen activator within 4.5 h of onset is effective for acute ischemic stroke. However, only small proportion of patients is treated due to delayed presentation. We aimed to examine the factors associated with delays of stroke patients in Riyadh, Saudi Arabia. Methods: A cross-sectional survey was conducted at King Abdulaziz Medical City, Riyadh, Saudi Arabia, during a 6-month period. An interviewer administered structured questionnaire addressed to the acute stroke patients or their relatives was used to explore the factors associated with delayed arrival. Results: A total of 227 patients attending the emergency department were interviewed. The mean age was 60.4 ± 15.6 years. Approximately 56.4% presented after 4.5 h of stroke onset. Factors associated with late arrival were being alone during the onset of stroke, not being transported in an ambulance, not knowing that they were experiencing a stroke, and residing outside the city of Riyadh. Conclusion: More than half of patients missed the golden hours for thrombolysis due to delayed presentation. Reasons include lack of knowledge, underuse of ambulance and difficult access to care. Urgent community-based interventions are needed to address these factors.

Background and Objectives. Tissue plasminogen activator (t-PA) within 4.5 hours from onset improves outcome in patients with ischemic stroke and has been recommended by several international guidelines. Since its approval in 1996, the debate among emergency physicians continues particularly around the result interpretation of the first positive randomized controlled trial, the National Institute of Neurological Disorders and Stroke (NINDS) clinical trial. This lack of consensus might negatively affect the delivery of effective stroke care. Here we aimed to assess the knowledge and attitude of Saudi emergency physicians toward t-PA use within 4.5 hours of onset in acute ischemic stroke. Methods. A web-based, self-administered, locally designed questionnaire was sent to all emergency physicians practicing in the city of Riyadh from January to September 2017. Results. Out of 450 emergency physicians, 122 from ten hospitals in Riyadh participated in the survey, with a 27% response rate. The majority of participants were men (78%), and their mean age was 40 ± 8 years. Half of the participants were board certified, and 36% were consultants. Half of the participants consider the evidence for t-PA use in stroke within 4.5 hours of stroke onset to be controversial, and 41% recommend against its use due to lack of proven efficacy (37%), the risk of hemorrhagic complications (35%), lack of stroke expertise (21%), and medicolegal liability (9%). Nearly half were willing to administer IV t-PA for ischemic stroke in collaboration with remote stroke neurology consultation if telestroke is implemented. Conclusion. Our study detected inadequate knowledge and a negative attitude among Saudi emergency physicians toward t-PA use in acute stroke. This might negatively impact patient outcome. Therefore, we recommend developing urgent strategies to improve emergency physicians’ knowledge, attitudes, and beliefs in the management of acute stroke.

Background: It is unclear whether screening for sepsis using an electronic alert in hospitalized ward patients improves outcomes. The objective of the Stepped-wedge Cluster Randomized Trial of Electronic Early Notification of Sepsis in Hospitalized Ward Patients (SCREEN) trial is to evaluate whether an electronic screening for sepsis compared to no screening among hospitalized ward patients reduces all-cause 90-day in-hospital mortality. Methods and design: This study is designed as a stepped-wedge cluster randomized trial in which the unit of randomization or cluster is the hospital ward. An electronic alert for sepsis was developed in the electronic medical record (EMR), with the feature of being active (visible to treating team) or masked (inactive in EMR frontend for the treating team but active in the backend of the EMR). Forty-five clusters in 5 hospitals are randomized into 9 sequences of 5 clusters each to receive the intervention (active alert) over 10 periods, 2 months each, the first being the baseline period. Data are extracted from EMR and are compared between the intervention (active alert) and control group (masked alert). During the study period, some of the hospital wards were allocated to manage patients with COVID-19. The primary outcome of all-cause hospital mortality by day 90 will be compared using a generalized linear mixed model with a binary distribution and a log-link function to estimate the relative risk as a measure of effect. We will include two levels of random effects to account for nested clustering within wards and periods and two levels of fixed effects: hospitals and COVID-19 ward status in addition to the intervention. Results will be expressed as relative risk with a 95% confidence interval. Conclusion: The SCREEN trial provides an opportunity for a novel trial design and analysis of routinely collected and entered data to evaluate the effectiveness of an intervention (alert) for a common medical problem (sepsis in ward patients). In this statistical analysis plan, we outline details of the planned analyses in advance of trial completion. Prior specification of the statistical methods and outcome analysis will facilitate unbiased analyses of these important clinical data. Trial registration: ClinicalTrials.gov NCT04078594.
