Maternal mortality in Lebanon: Increased vulnerability among Syrian refugees

OBJECTIVE

To compare the burden and causes of maternal deaths between Syrian and Lebanese women for the period of 2010-2018.

METHODS

A retrospective analysis was conducted of maternal deaths from the national notification system at the Ministry of Public Health in Lebanon during the period of 2010-2018. Maternal deaths among Syrian refugees and Lebanese citizens were compared based on cause of death, age of the woman, and nationality. Causes of maternal deaths were categorized as direct and indirect following WHO definitions.

RESULTS

The maternal mortality ratio among the Syrian refugee women in Lebanon was higher than that of Lebanese women in the period 2010-2018, with its highest rate of 55.1 in 2017. Hemorrhage and indirect causes of maternal deaths are more common among Syrian refugee women whereas embolism and hypertension have higher proportions among Lebanese women. Maternal deaths within 48 h after birth are more common among Syrian than Lebanese women.

CONCLUSION

Syrian refugee women carry an increased risk for maternal mortality in Lebanon. Improving timely access and equitable provision of appropriate care should be a priority for the health system in Lebanon.

Understanding Preventable Deaths in the Geriatric Trauma Population: Analysis of 3,452,339 Patients From the Center of Medicare and Medicaid Services Database

BACKGROUND

Patient safety indicators (PSIs) are avoidable complications that can impact outcomes. Geriatric patients have a higher mortality than younger patients with similar injuries, and understanding the etiology may help reduce mortality. We aim to estimate preventable geriatric trauma mortality in the United States and identify PSIs associated with increased preventable mortality.

METHODS

A retrospective cohort study of patients aged ≥65 years, in the CMS database, 2017-second quarter of 2020. Risk-adjusted multivariable regression was performed to calculate observed-to-expected (O/E) mortality ratios for failure-to-prevent and failure-to-rescue PSIs with significance defined as P < .05.

RESULTS

3,452,339 geriatric patients were analyzed. Patients aged 75-84 years had 33% higher odds of preventable mortality (adjusted odds ratio [aOR] = 1.33 and 95% confidence interval [CI] = 1.31, 1.36), whereas patients aged ≥85 years had 91% higher odds of preventable mortality (aOR = 1.91 and 95% CI = 1.87, 1.94) compared to patients aged 65-74 years. Failure-to-prevent O/E were >1 for all PSIs evaluated with central line-related blood stream infection having a high O/E (747.93). Failure-to-rescue O/E were >1 for 10/11 (91%) PSIs with physiologic and metabolic derangements having the highest O/E (5.98). United States' states with higher quantities of geriatric trauma patients experienced reduced preventable mortality.

CONCLUSION

Odds of preventable mortality increases with age. Perioperative venous thrombotic events, hemorrhage or hematoma, and postoperative physiologic/metabolic derangements produce significant preventable mortalities. United States' states differ in their failure-to-prevent and failure-to-rescue PSIs. Utilization of national guidelines, minimization of central venous catheter use, addressing polypharmacy especially anticoagulation, ensuring operative and procedure-based competencies, and greater incorporation of inpatient geriatricians may serve to reduce preventable mortality in elderly trauma patients.

The Association between Material Deprivation and Avoidable Mortality in Lisbon, Portugal

There is considerable evidence pointing to the existence of a socioeconomic gradient in mortality, which tends to be steeper in urban areas. Similar to other European cities, Lisbon is far from homogeneous since considerable geographical inequalities exist between the more advantaged and the more deprived neighborhoods. The main goals of this study are to describe the geographical pattern of premature deaths (before 65 years old), avoidable deaths (preventable and amenable to healthcare) and cause-specific mortality (HIV/AIDS and suicide) in Lisbon, at the lower administrative level (civil parish, in Portuguese: Freguesia), and analyze the statistical association between mortality risk and deprivation, before (1999–2003) and during the economic crisis (2008–2012). Smoothed Standardized Mortality Ratios (sSMR) and Relative Risk (RR) with 95% credible intervals were calculated to identify the association between mortality and deprivation. The analysis of the geographical distribution of cause-specific mortality reveals that civil parishes with high sSMR in the first period continued to present higher mortality rates in the second. Moreover, a significant statistical association was found between all the causes of death and deprivation, except suicide. These findings contribute to understanding how social conditions influence health outcomes and can offer insights about potential policy directions for local government.

Development of Optimized Tissue-Factor-Targeted Peptide Amphiphile Nanofibers to Slow Noncompressible Torso Hemorrhage

Noncompressible torso hemorrhage accounts for a significant portion of preventable trauma deaths. We report here on the development of injectable, targeted supramolecular nanotherapeutics based on peptide amphiphile (PA) molecules that are designed to target tissue factor (TF) and, therefore, selectively localize to sites of injury to slow hemorrhage. Eight TF-targeting sequences were identified, synthesized into PA molecules, coassembled with nontargeted backbone PA at various weight percentages, and characterized via circular dichroism spectroscopy, transmission electron microscopy, and X-ray scattering. Following intravenous injection in a rat liver hemorrhage model, two of these PA nanofiber coassemblies exhibited the most specific localization to the site of injury compared to controls (p < 0.05), as quantified using immunofluorescence imaging of injured liver and uninjured organs. To determine if the nanofibers were targeting TF in vivo, a mouse saphenous vein laser injury model was performed and showed that TF-targeted nanofibers colocalized with fibrin, demonstrating increased levels of nanofiber at TF-rich sites. Thromboelastograms obtained using samples of heparinized rat whole blood containing TF demonstrated that no clots were formed in the absence of TF-targeted nanofibers. Lastly, both PA nanofiber coassemblies decreased blood loss in comparison to sham and backbone nanofiber controls by 35-59% (p < 0.05). These data demonstrate an optimal TF-targeted nanofiber that localizes selectively to sites of injury and TF exposure, and, interestingly, reduces blood loss. This research represents a promising initial phase in the development of a TF-targeted injectable therapeutic to reduce preventable deaths from hemorrhage.

A mortality review of adult inpatients with tuberculosis in Mendi, Papua New Guinea

SETTING

Mendi Provincial Hospital, Southern Highlands Province, Papua New Guinea (PNG).

BACKGROUND

PNG is a high burden country for tuberculosis (TB) and TB-human immunodeficiency virus (HIV). TB is the second most common cause of death in PNG.

OBJECTIVE

To identify the number of adult inpatients with TB who died between 1 January 2015 and 30 August 2017; describe these patients' characteristics and identify contributing factors that could be modified.

DESIGN

This was a retrospective case series review.

RESULTS

Among 905 inpatients with TB during the study period, there were 90 deaths. The patients who died were older than those who survived (median age 40 years vs. 32 years, P = 0.011). The majority of patients who died lived less than 3 hours from the hospital (71%), were diagnosed after admission (79%) and were clinically diagnosed (77%). HIV status was not known in 50% of the deaths. Of patients with a known status, 27% (12/45) were HIV-positive. The median symptom duration prior to presentation was 28 days, with females presenting later than males (84 vs. 28 days, P = 0.008).

CONCLUSION

This study highlights areas where community and hospital-based management of TB could be improved to potentially reduce TB mortality, including earlier detection and treatment, improved bacteriological diagnosis and increased HIV testing.

The prevalence of potentially preventable deaths in an acute care hospital: A retrospective cohort

Studies estimate that 6% to 27% of deaths in hospitals might be prevented with higher quality care. These estimates may be inaccurate because they fail to account for the uncertainty associated with classifying preventability. The purpose of this study was to measure the prevalence of preventable deaths, accounting for the uncertainty in preventability ratings.We created standardized structured case abstracts for all deaths at a multisite academic teaching hospital over a 3-month period. Each case abstract was evaluated independently by 4 reviewers who rated death preventability on a 100-point scale ranging from 0 ("Definitely not preventable") to 100 ("Definitely preventable"). Ratings were categorized into a 4-level ordinal scale and latent class analysis was used to measure the prevalence of each preventability class and estimate the probability that deaths in each class were preventable.There were 480 deaths (3.4% of all admissions) during the study period. The latent class model (LCM) found that 91.6% (95% CI: 88.4-94.8%) of deaths were "nonpreventable" and 8.4% (5.2-11.6%) were "possibly preventable." "Possibly preventable" deaths could be identified with 90% certainty, but due to error in reviewer ratings, a "possibly preventable" death had a 50% probability of being receiving a rating of less than 25/100 by any single reviewer. Only 5 of 31 deaths classified as a "possibly preventable" (1.0% of all deaths) were judged to likely be alive in 3 months with perfect care.After accounting for uncertainty associated with rating the preventability of hospital deaths, we found that 8.4% of deaths were deemed possibly preventable. There was only moderate probability that these deaths were truly preventable.

Pattern of unnatural deaths among children: An autopsy study

This study was conducted at the M. S. Ramaiah Medical College, Bangalore, between October 2007 and September 2009 to analyse the age and sex distribution of unnatural deaths in children, patterns and manner of death. Detailed information regarding the circumstances of death was sought from the relatives, friends and police. The scene of occurrence was visited, and photographs of the scene of occurrence were examined in relevant cases. Unnatural deaths in children constituted 6.62% of the total autopsies conducted. The majority of childhood deaths were in the age group of 15-18 years of both sexes constituting 46.88%. Males constituted 55.22% of cases. Suicide accounted for 40.63% of the cases. Most children committed suicide by hanging (82.05%). The main reason was academic failure and some of the cases were accidental (48.96%). Road traffic accidents accounted for 26.04% of the cases, where most children were pedestrians (56%). Drowning accounted for 15.63% of the cases. Most of the children drowned while playing near ponds (83.33%). Homicide accounted for 9.36% of the cases - either killed by their mother as part of a pedicide-suicide event or by the father, and in two cases the children were sexually abused before being killed.

Health Promotion Methods for Smoking Prevention and Cessation: A Comprehensive Review of Effectiveness and the Way Forward

Tobacco smoking is one of the greatest causes of mortality in the world, responsible for over 5 million deaths per annum. The prevalence of smoking is over 1 billion people, with the majority coming from low or middle income countries. Yet, the incidence of smoking varies vastly between many countries. Some countries have been able to decline the smoking and tobacco related morbidity and mortality through the introduction of health promotion initiatives and effective policies in order to combat tobacco usage. However, on the other hand, in some countries, the incidence of smoking is increasing still further. With the growing body of evidence of detriment of tobacco to health, many control policies have been implemented as health promotion actions. Such methods include taxation of smoking, mass advertising campaigns in the media, peer education programs, community mobilization, motivational interviewing, health warnings on tobacco products, marketing restrictions, and banning smoking in public places. However, the review of the effectiveness of various health promotion methods used for smoking prevention and cessation is lacking. Therefore, the aim of this review is to identify and critically review the effectiveness of health promotion methods used for smoking prevention and cessation. All available studies and reports published were considered. Searches were conducted using PubMed, MEDLINE, Ovid, Karger, ProQuest, Sage Journals, Science Direct, Springer, Taylor and Francis, EMBASE, CINAHL, and Cochrane and Wiley Online Library. Various relevant search terms and keywords were used. After considering the inclusion and exclusion criteria, we selected 23 articles for the present review.

Preventable deaths in patients admitted from emergency department

BACKGROUND

There is limited data about how appropriate medical care is in the emergency department (ED).

OBJECTIVES

To investigate the rate and types of preventable deaths among patients with early mortality after emergency admission from the ED.

METHODS

We retrospectively reviewed charts of early mortality (defined as mortality which occurred within 24 hours after admission from the ED) over a 3 year period. Those patients with terminal cancer or out of hospital cardiac arrest (OHCA) at presentation were excluded. Two independent assessors reviewed each eligible chart and determined whether early mortality was preventable. Any disagreements were resolved through discussion between the investigators. A mortality event was considered preventable if actions or missed actions were identified that would have prevented the death. The types of preventability were categorised as misdiagnosis, delayed diagnosis, and inappropriate medical management. Interrater reliability in the initial determination was assessed using Cohen kappa statistic.

RESULTS

Over a 3 year period, 210 early mortality cases were identified. Excluding patients with terminal cancer or OHCA, the rate of preventable deaths was 25.8% (32/124). The types of preventability were inappropriate medical management (17 patients), delayed diagnosis (eight), and misdiagnosis (seven). There was good agreement between assessors with a Cohen kappa statistic of 0.81.

CONCLUSIONS

Preventable deaths in emergency admitted patients with early mortality are not uncommon. Analysis and identification of preventability early mortality by using a chart based method may be used as a quality assurance index in emergency medical care.
