Biogas Stoves Reduce Firewood Use, Household Air Pollution, and Hospital Visits in Odisha, India.

Traditional cooking using biomass is associated with ill health, local environmental degradation, and regional climate change. Clean stoves (liquefied petroleum gas (LPG), biogas, and electric) are heralded as a solution, but few studies have demonstrated their environmental health benefits in field settings. We analyzed the impact of mainly biogas (as well as electric and LPG) stove use on social, environmental, and health outcomes in two districts in Odisha, India, where the Indian government has promoted household biogas. We established a cross-sectional observational cohort of 105 households that use either traditional mud stoves or improved cookstoves (ICS). Our multidisciplinary team conducted surveys, environmental air sampling, fuel weighing, and health measurements. We examined associations between traditional or improved stove use and primary outcomes, stratifying households by proximity to major industrial plants. ICS use was associated with 91% reduced use of firewood (p < 0.01), substantial time savings for primary cooks, a 72% reduction in PM2.5, a 78% reduction in PAH levels, and significant reductions in water-soluble organic carbon and nitrogen (p < 0.01) in household air samples. ICS use was associated with reduced time in the hospital with acute respiratory infection and reduced diastolic blood pressure but not with other health measurements. We find many significant gains from promoting rural biogas stoves in a context in which traditional stove use persists, although pollution levels in ICS households still remained above WHO guidelines.

Impact of patient-centered communication on patient satisfaction scores in patients with chronic life-limiting illnesses: an experience from Kenya.

Background: Patient satisfaction remains a key area of interest worldwide; utilizing a patient-centered communication approach, particularly with patients with chronic life-limiting illnesses may be one way to achieve this. However, there is a dearth of empirical information on the effect of patient-centered communication strategies in patients with chronic life-limiting illnesses in Kenya on patient satisfaction. Objectives: The objective of this study was to assess the impact of patient-centered communication on patient satisfaction. Methods: We conducted our study at a tertiary teaching and referral hospital in Kenya. We utilized a quasi-experimental pre-test post-test study design and engaged 301 adult medical in-patients with chronic life limiting conditions. We randomized them to receive patient-centered communication, and evaluated the change in patient satisfaction scores using an adapted Medical Interview satisfaction Scale 21 (MISS 21). Results: Two hundred and seventy-eight out of 301 recruited participants completed the study. The baseline characteristics of the participants randomized to the control and intervention arms were similar. Although both the control and intervention arms had a decline in the mean difference scores, the intervention arm recorded a larger decline, -15.04 (-20.6, -9.47) compared to -7.87 (-13.63, -2.12), with a statistically significant mean difference between the two groups at -7.16 (-9.67, -4.46). Participants in the intervention arm were less likely to: understand the cause of their illness (p < 0.001), understand aspects of their illness (p < 0.001), understand the management plan (p < 0.001), receive all the relevant information on their health (p < 0.001), and to receive adequate self-care information (p < 0.001). They were also less likely to acknowledge a good interpersonal relationship with the healthcare providers (p < 0.001), to feel comfortable discussing private issues (p < 0.004), and to feel that the consultation time was adequate (p < 0.001). Conclusion and recommendation: Contrary to expectation, patient-centered communication did not result in improved patient satisfaction scores. Further studies can evaluate factors affecting and explaining this relationship and assess intermediate and long-term effects of provision of a patient-centered communication in diverse global contexts.

Tuberculosis is Associated with Chronic Hypoxemia among Kenyan Adults (CHAKA): A Case-Control Study.

RATIONALE: Data on risk factors for chronic hypoxemia in low and middle-income countries are lacking. OBJECTIVE: We aimed to quantify the association between potential risk factors and chronic hypoxemia among adults hospitalized in Kenya. METHODS: A hospital-based case-control study was conducted at Moi Teaching and Referral Hospital in Eldoret, Kenya. Adult inpatients were screened on admission and enrolled in a 1:2 case to control ratio. Cases were patients with chronic hypoxemia, defined as a resting oxygen saturation (SpO2) < 88% on admission and either a one-month post discharge SpO2 < 88% or, if they died prior to follow-up, a documented SpO2 < 88% in the 6 months prior to enrollment. Controls were randomly selected, stratified by sex, among non-hypoxemic inpatients. Data were collected via questionnaires and structured chart review. Regression was used to assess the association between chronic hypoxemia and age, sex, smoking status, biomass fuel use, elevation, and self-reported history of tuberculosis and HIV diagnosis. Odds ratios (ORs) and 95% confidence intervals (CIs) are reported. RESULTS: The study enrolled 108 chronically hypoxemic cases and 240 non-hypoxemic controls. In multivariable analysis, as compared to controls, chronically hypoxemic cases had significantly higher odds of older age (OR 1.2 per 5-year increase; 95% CI: 1.1-1.3), female sex (OR 3.6, 95% CI: 1.8-7.2), current or former tobacco use (OR 4.7, 95% CI: 2.3-9.6) and prior tuberculosis (OR 11.8, 95% CI: 4.7-29.6), but no increase in odds of HIV diagnosis and biomass fuel use. CONCLUSION: These findings highlight the potential impact of prior tuberculosis on chronic lung disease in Kenya and the need for further studies on post-tuberculosis lung disease.

Distressed Work: Chronic Imperatives and Distress in Covid-19 Critical Care.

This ethnographic study introduces the term "distressed work" to describe the emergence of chronic frictions between moral imperatives for health care workers to keep working and the dramatic increase in distress during the Covid-19 pandemic. Interviews and observant participation conducted in a hospital intensive care unit during the Covid-19 pandemic reveal how health care workers connected job duties with extraordinary emotional, physical, and moral burdens. We explore tensions between perceived obligations of health care professionals and the structural contexts of work. Key findings cluster around the moral imperatives of health care work and the distress that work engendered as work spaces, senses of vocation, patient and family interactions, and end-of-life care shifted. While the danger of working beyond limits has long been an ordinary feature of health care work, it has now become a chronic crisis. Assessing this problem in terms of distressed work and its structural contexts can better address effective, worker-informed responses to current health care labor dilemmas.

Asthma, Airflow Obstruction, and Eosinophilic Airway Inflammation Prevalence in Western Kenya: A Population-Based Cross-Sectional Study.

Objectives: Determine the prevalence of airway disease (e.g., asthma, airflow obstruction, and eosinophilic airway inflammation) in Kenya, as well as related correlates of airway disease and health-related quality of life. Methods: A three-stage, cluster-randomized cross-sectional study in Uasin Gishu County, Kenya was conducted. Individuals 12 years and older completed questionnaires (including St. George's Respiratory Questionnaire for COPD, SGRQ-C), spirometry, and fractional exhaled nitric oxide (FeNO) testing. Prevalence ratios with 95% confidence intervals (CIs) were calculated. Multivariable models were used to assess correlates of airflow obstruction and high FeNO. Results: Three hundred ninety-two participants completed questionnaires, 369 completed FeNO testing, and 305 completed spirometry. Mean age was 37.5 years; 64% were women. The prevalence of asthma, airflow obstruction on spirometry, and eosinophilic airway inflammation was 21.7%, 12.3% and 15.7% respectively in the population. Women had significantly higher SGRQ-C scores compared to men (15.0 vs. 7.7). Wheezing or whistling in the last year and SGRQ-C scores were strongly associated with FeNO levels >50 ppb after adjusting for age, gender, BMI, and tobacco use. Conclusion: Airway disease is a significant health problem in Kenya affecting a young population who lack a significant tobacco use history.

Prevalence and phenotypic trajectories of hypoxaemia among hospitalised adults in Kenya: a single-centre, prospective cohort study.

OBJECTIVE: Global medical oxygen security is limited by knowledge gaps in hypoxaemia burden and oxygen access in low-income and middle-income countries. We examined the prevalence and phenotypic trajectories of hypoxaemia among hospitalised adults in Kenya, with a focus on chronic hypoxaemia. DESIGN: Single-centre, prospective cohort study. SETTING: National tertiary referral hospital in Eldoret, Kenya between September 2019 and April 2022. PARTICIPANTS: Adults (age ≥18 years) admitted to general medicine wards. PRIMARY AND SECONDARY OUTCOME MEASURES: Our primary outcome was proportion of patients who were hypoxaemic (oxygen saturation, SpO2 ≤88%) on admission. Secondary outcomes were proportion of patients with hypoxaemia on admission who had hypoxaemia resolution, hospital discharge, transfer, or death among those with unresolved hypoxaemia or chronic hypoxaemia. Patients remaining hypoxaemic for ≤3 days after admission were enrolled into an additional cohort to determine chronic hypoxaemia. Chronic hypoxaemia was defined as an SpO2 ≤ 88% at either 1-month post-discharge follow-up or, for patients who died prior to follow-up, a documented SpO2 ≤88% during a previous hospital discharge or outpatient visit within the last 6 months. RESULTS: We screened 4104 patients (48.5% female, mean age 49.4±19.4 years), of whom 23.8% were hypoxaemic on admission. Hypoxaemic patients were significantly older and more predominantly female than normoxaemic patients. Among those hypoxaemic on admission, 33.9% had resolution of their hypoxaemia as inpatients, 55.6% had unresolved hypoxaemia (31.0% died before hospital discharge, 13.3% were alive on discharge and 11.4% were transferred) and 10.4% were lost to follow-up. The prevalence of chronic hypoxaemia was 2.1% in the total screened population, representing 8.8% of patients who were hypoxaemic on admission. Chronic hypoxaemia was determined at 1-month post-discharge among 59/86 patients and based on prior documentation among 27/86 patients. CONCLUSION: Hypoxaemia is highly prevalent among adults admitted to a general medicine ward at a national referral hospital in Kenya. Nearly 1 in 11 patients who are hypoxaemic on admission are chronically hypoxaemic.

Feasibility of Cardiac Rehabilitation Models in Kenya.

BACKGROUND: Heart failure (HF), is a leading cause of cardiovascular morbidity and mortality in Sub-Saharan Africa. Cardiac rehabilitation (CR) is known to improve functional capacity and reduce morbidity associated with HF. Although CR is a low-cost intervention, global access and adherence rates to CR remain poor. In regions such as Western Kenya, CR programs do not exist. We sought to establish the feasibility CR for HF in this region by testing adherence to institution and home-based models of CR. METHODS: One hundred participants with New York Heart Association (NYHA) class II and III HF symptoms were prospectively enrolled from a tertiary health facility in Western Kenya. Participants were non-randomly assigned to participate in one of two CR models based on their preference. Institution based cardiac rehabilitation (IBCR) comprised 36 facility-based exercise sessions over a period of 12 weeks. Home based cardiac rehabilitation (HBCR) comprised weekly pedometer guided exercise targets over a period of 12 weeks. An observational arm (OA) receiving usual care was also enrolled. The primary endpoint of CR feasibility was assessed based on study participants to adherence to at least 25% of exercise sessions. Secondary outcomes of change in NYHA symptom class, and six-minute walk time distance (6MWTD) were also evaluated. Data were summarized and analyzed as means (SD) and frequencies. Paired t-tests, Chi Square, Fisher's, and ANOVA tests were used for comparisons. FINDINGS: Mean protocol adherence was greater than 25% in both CR models; 46% ± 18 and 29% ± 11 (P < 0.05) among IBCR and HBCR participants respectively. Improvements by at least one NYHA class were observed among 71%, 41%, and 54%, of IBCR, HBCR and OA participants respectively. 6MWTD increased significantly by a mean of 31 ± 65 m, 40 ± 55 m and 38 ± 71 m in the IBCR, HBCR and OA respectively (P < 0.05). CONCLUSIONS: IBCR and HBCR, are feasible rehabilitation models for HF in Western Kenya. Whereas improvement in functional capacity was observed, effectiveness of CR in this population remains unknown. Future randomized studies evaluating effect size, long term efficacy, and safety of cardiac rehabilitation in low resource settings such as Kenya are recommended.

Opportunities for Improving Antimicrobial Stewardship: Findings From a Prospective, Multi-Center Study in Three Low- or Middle-Income Countries.

Background: To develop effective antimicrobial stewardship programs (ASPs) for low- and middle-income countries (LMICs), it is important to identify key targets for improving antimicrobial use. We sought to systematically describe the prevalence and patterns of antimicrobial use in three LMIC hospitals. Methods: Consecutive patients admitted to the adult medical wards in three tertiary care hospitals in Tanzania, Kenya, and Sri Lanka were enrolled in 2018-2019. The medical record was reviewed for clinical information including type and duration of antimicrobials prescribed, indications for antimicrobial use, and microbiologic testing ordered. Results: A total of 3,149 patients were enrolled during the study period: 1,103 from Tanzania, 750 from Kenya, and 1,296 from Sri Lanka. The majority of patients were male (1,783, 56.6% overall) with a median age of 55 years (IQR 38-68). Of enrolled patients, 1,573 (50.0%) received antimicrobials during their hospital stay: 35.4% in Tanzania, 56.5% in Kenya, and 58.6% in Sri Lanka. At each site, the most common indication for antimicrobial use was lower respiratory tract infection (LRTI; 40.2%). However, 61.0% received antimicrobials for LRTI in the absence of LRTI signs on chest radiography. Among patients receiving antimicrobials, tools to guide antimicrobial use were under-utilized: microbiologic cultures in 12.0% and microbiology consultation in 6.5%. Conclusion: Antimicrobials were used in a substantial proportion of patients at tertiary care hospitals across three LMIC sites. Future ASP efforts should include improving LRTI diagnosis and treatment, developing antibiograms to direct empiric antimicrobial use, and increasing use of microbiologic tests.

Use of a Novel Trigger Tool to Identify Palliative Care Needs in Surgical Patients at a National Referral Hospital in Kenya: A Pilot Study.

Background: Addressing unmet palliative care needs in high-risk surgical patients in low- and middle-income countries must include innovative approaches to limitations in personnel and culturally acceptable assessment modalities. Objectives: We assessed the utility of a novel seven-item "Step-1" trigger tool in identifying surgical patients who may benefit from palliative care. Design: All adult patients (≥18 years) on general surgery, neurosurgery, and orthopedic surgery wards were enrolled over a four-month period. Setting/Subjects: This study took place at Moi Teaching and Referral Hospital (MTRH), one of two Kenyan national referral hospitals. Measurements: The "Step-1" trigger tool was administered, capturing provider estimates of prognosis, cancer history, social barriers, admission frequency, hospice history, symptom burden, and functional decline/wasting. A cut-point of ≥3 positive factors was selected, indicating a patient may benefit from palliative care. Results: A total of 411 patients were included for analysis. Twenty-five percent (n = 102) of patients had scores ≥3. The cut-point of ≥3 was significantly associated with identifying high-risk patients (HRP; χ2 = 32.3, p < 0.01), defined as those who died or were palliatively discharged, with a sensitivity and specificity of 63.9% and 78.9%, respectively. Survey questions with the highest overall impact included: "Would you be not surprised if the patient died within 12 months?," "Are there uncontrolled symptoms?," and "Is there functional decline/wasting?" Conclusions: This pilot study demonstrates that the "Step-One" trigger tool is a simple and effective method to identify HRP in resource-limited settings. Although this study identified three highly effective questions, the seven-question assessment is flexible and can be adapted to different settings.

Oxygen delivery systems for adults in Sub-Saharan Africa: A scoping review.

BACKGROUND: Respiratory diseases are the leading cause of death and disability worldwide. Oxygen is an essential medicine used to treat hypoxemia from respiratory diseases. However, the availability and utilization of oxygen delivery systems for adults in sub-Saharan Africa is not well-described. We aim to identify and describe existing data around oxygen availability and provision for adults in sub-Saharan Africa, determine knowledge or research gaps, and make recommendations for future research and capacity building. METHODS: We systematically searched four databases for articles on April 22, 2020, for variations of keywords related to oxygen with a focus on countries in sub-Saharan Africa. Inclusion criteria were studies that included adults and addressed hypoxemia assessment or outcome, oxygen delivery mechanisms, oxygen availability, oxygen provision infrastructure, and oxygen therapy and outcomes. RESULTS: 35 studies representing 22 countries met inclusion criteria. Availability of oxygen delivery systems ranged from 42%-94% between facilities, with wide variability in the consistency of availability. There was also wide reported prevalence of hypoxemia, with most studies focusing on specific populations. In facilities where oxygen is available, health care workers are ill-equipped to identify adult patients with hypoxemia, provide oxygen to those who need it, and titrate or discontinue oxygen appropriately. Oxygen concentrators were shown to be the most cost-effective delivery system in areas where power is readily available. CONCLUSIONS: There is a substantial need for building capacity for oxygen delivery throughout sub-Saharan Africa. Addressing this critical issue will require innovation and a multi-faceted approach of developing infrastructure, better equipping facilities, and health care worker training.

Barriers to implementing antimicrobial stewardship programs in three low- and middle-income country tertiary care settings: findings from a multi-site qualitative study.

BACKGROUND: Antimicrobial resistance has been named as one of the top ten threats to public health in the world. Hospital-based antimicrobial stewardship programs (ASPs) can help reduce antimicrobial resistance. The purpose of this study was to determine perceived barriers to the development and implementation of ASPs in tertiary care centers in three low- and middle-income countries (LMICs). METHODS: Interviews were conducted with 45 physicians at tertiary care hospitals in Sri Lanka (n = 22), Kenya (12), and Tanzania (11). Interviews assessed knowledge of antimicrobial resistance and ASPs, current antimicrobial prescribing practices, access to diagnostics that inform antimicrobial use, receptiveness to ASPs, and perceived barriers to implementing ASPs. Two independent reviewers coded the interviews using principles of applied thematic analysis, and comparisons of themes were made across the three sites. RESULTS: Barriers to improving antimicrobial prescribing included prohibitively expensive antimicrobials, limited antimicrobial availability, resistance to changing current practices regarding antimicrobial prescribing, and limited diagnostic capabilities. The most frequent of these barriers in all three locations was limited drug availability. Many physicians in all three sites had not heard of ASPs before the interviews. Improved education was a suggested component of ASPs at all three sites. The creation of guidelines was also recommended, without prompting, by interviewees at all three sites. Although most participants felt microbiological results were helpful in tailoring antibiotic courses, some expressed distrust of laboratory culture results. Biomarkers like erythrocyte sedimentation rate and c-reactive protein were not felt to be specific enough to guide antimicrobial therapy. Despite limited or no prior knowledge of ASPs, most interviewees were receptive to implementing protocols that would include documentation and consultation with ASPs regarding antimicrobial prescribing. CONCLUSIONS: Our study highlighted several important barriers to implementing ASPs that were shared between three tertiary care centers in LMICs. Improving drug availability, enhancing availability of and trust in microbiologic data, creating local guidelines, and providing education to physicians regarding antimicrobial prescribing are important steps that could be taken by ASPs in these facilities.

Investigating SOFA, delta-SOFA and MPM-III for mortality prediction among critically ill patients at a private tertiary hospital ICU in Kenya: A retrospective cohort study.

BACKGROUND: Outcomes in well-resourced, intensive care units (ICUs) in Kenya are thought to be comparable to those in high-income countries (HICs) but risk-adjusted mortality data is unavailable. We undertook an evaluation of the Aga Khan University Hospital, Nairobi ICU to analyze patient clinical-demographic characteristics, compare the performance of Sequential Organ Failure Assessment (SOFA), delta-SOFA at 48 hours and Mortality Prediction Model-III (MPM-III) mortality prediction systems, and identify factors associated with increased risk of mortality. METHODS: A retrospective cohort study was conducted of adult patients admitted to the ICU between January 2015 and September 2017. SOFA and MPM-III scores were determined at admission and SOFA repeated at 48 hours. RESULTS: Approximately 33% of patients did not meet ICU admission criteria. Mortality among the population of critically ill patients in the ICU was 31.7%, most of whom were male (61.4%) with a median age of 53.4 years. High adjusted odds of mortality were found among critically ill patients with leukemia (aOR 6.32, p<0.01), tuberculosis (aOR 3.96, p<0.01), post-cardiac arrest (aOR 3.57, p<0.01), admissions from the step-down unit (aOR 3.13, p<0.001), acute kidney injury (aOR 2.97, p<0.001) and metastatic cancer (aOR 2.45, p = 0.04). The area under the receiver-operating characteristic (ROC) curve of admission SOFA was 0.77 (95% CI, 0.73-0.81), MPM-III 0.74 (95% CI, 0.69-0.79), delta-SOFA 0.69 (95% CI, 0.63-0.75) and 48-hour SOFA 0.83 (95% CI, 0.79-0.87). The difference between SOFA at 48 hours and admission SOFA, MPM-III and delta-SOFA was statistically significant (chi2 = 17.1, 24.2 and 26.5 respectively; p<0.001). Admission SOFA, MPM-III and 48-hour SOFA were well calibrated (p >0.05) while delta-SOFA was borderline (p = 0.05). CONCLUSION: Mortality among the critically ill was higher than expected in this well-resourced ICU. 48-hour SOFA performed better than admission SOFA, MPM-III and delta-SOFA in our cohort. While a large proportion of patients did not meet admission criteria but were boarded in the ICU, critically ill patients stepped-up from the step-down unit were unlikely to survive. Patients admitted following a cardiac arrest, and those with advanced disease such as leukemia, stage-4 HIV and metastatic cancer, had particularly poor outcomes. Policies for fair allocation of beds, protocol-driven admission criteria and appropriate case selection could contribute to lowering the risk of mortality among the critically ill to a level on par with HICs.

Knowledge and Perceptions Regarding Palliative Care Among Religious Leaders in Uasin Gishu County, Kenya: Survey and Focus Group Analysis.

Spirituality and religion are at the core of Kenyan life. Pastoral leaders play a key role in shaping the individual and community's response to living with chronic and life-threatening illnesses. Involvement of religious leaders would therefore be critical in advocacy and education efforts in palliative care (PC) to address the needs of this population. The goal of this study was to evaluate the knowledge and perceptions of religious leaders in Western Kenya regarding PC. This was a mixed-methods study with 86 religious leaders utilizing a 25-question survey followed by 5-person focus group discussions. Eighty-one percent of participants agreed that pastors should encourage members with life-threatening illnesses to talk about death and dying. However, almost a third of participants (29%) also agreed with the statement that full use of PC can hasten death. The pastors underscored challenges in end-of-life spiritual preparation as well as the importance of traditional beliefs in shaping cultural norms. Pastors supported the need for community-based PC education and additional training in PC for religious leaders. The results of this study confirm the dominant role of religion and spirituality in PC in Kenya. This dominant role in shaping PC is tied closely to Kenyan attitudes and norms surrounding death and dying.

Intensive Care Outcomes and Mortality Prediction at a National Referral Hospital in Western Kenya.

RATIONALE: The burden of critical care is greatest in resource-limited settings. Intensive care unit (ICU) outcomes at public hospitals in Kenya are unknown. The present study is timely, given the Kenyan Ministry of Health initiative to expand ICU capacity. OBJECTIVES: To identify factors associated with mortality at Moi Teaching and Referral Hospital and validate the Mortality Probability Admission Model II (MPM0-II). METHODS: A retrospective cohort of 450 patients from January 1, 2013, to April 5, 2015, was evaluated using demographics, presenting diagnoses, interventions, mortality, and cost data. RESULTS: ICU mortality was 53.6%, and 30-day mortality was 57.3%. Most patients were male (61%) and at least 18 years old (70%); the median age was 29 years. Factors associated with high adjusted odds of mortality were as follows: age younger than 10 years (adjusted odds ratio [aOR], 3.59; P ≤ 0.001), ages 35-49 years (aOR, 3.13; P = 0.002), and age above 50 years (aOR, 2.86; P = 0.004), with reference age range 10-24 years; sepsis (aOR, 3.39; P = 0.01); acute stroke (aOR, 8.14; P = 0.011); acute respiratory failure or mechanical ventilation (aOR, 6.37; P < 0.001); and vasopressor support (aOR, 7.98; P < 0.001). Drug/alcohol poisoning (aOR, 0.33; P = 0.005) was associated with lower adjusted odds of mortality. MPM0-II discrimination showed an area under the receiver operating characteristic curve of 0.78 (95% confidence interval, 0.72-0.82). The result of the Hosmer-Lemeshow test for calibration was significant (P < 0.001). CONCLUSIONS: In a Kenyan public ICU, high mortality was noted despite the use of advanced therapies. MPM0-II has acceptable discrimination but poor calibration. Modification of MPM0-II or development of a new model using a prospective multicenter global collaboration is needed. Standardized triage and treatment protocols for high-risk diagnoses are needed to improve ICU outcomes.

Brain death determination: the imperative for policy and legal initiatives in Sub-Saharan Africa.

The concept of brain death (BD), defined as irreversible loss of function of the brain including the brainstem, is accepted in the medical literature and in legislative policy worldwide. However, in most of Sub-Saharan Africa (SSA) there are no legal guidelines regarding BD. Hypothetical scenarios based on our collective experience are presented which underscore the consequences of the absence of BD policies in resource-limited countries (RLCs). Barriers to the development of BD laws exist in an RLC such as Kenya. Cultural, ethnic, and religious diversity creates a complex perspective about death challenging the development of uniform guidelines for BD. The history of the medical legal process in the USA provides a potential way forward. Uniform guidelines for legislation at the state level included special consideration for ethnic or religious preferences in specific states. In SSA, medical and social consensus on the definition of BD is a prerequisite for the development BD legislation. Legislative policy will (1) limit prolonged and futile interventions; (2) mitigate the suffering of families; (3) standardise clinical practice; and (4) facilitate better allocation of scarce critical care resources in RLCs. There is a clear-cut need for these policies, and previous successful policies can serve to guide these efforts.

Assessment of healthcare personnel knowledge of stroke care at a large referral hospital in sub-Saharan Africa - A survey based approach.

There is no published literature regarding sub-Saharan health-care providers' understanding of stroke management patterns. Understanding current stroke management knowledge is important in formulating future education opportunities for providers to optimize patient outcomes. A cross-sectional survey of acute stroke diagnosis, hospital management, and secondary prevention questions was administered to health-care providers working in one large Kenyan acute referral hospital. Due to the prevalence of medical students (61.8%), an experienced-focused analysis contrasted students with more experienced providers. Providers (n=199) anonymously responded to the surveys. Among the acute diagnosis most respondents stated that stroke scales should always used (58.3% of respondents), 3h was the time period for alteplase (t-PA) (53.8% of respondents), and CT scan should be always be obtained prior to administration of anticoagulant therapy (61.3% of respondents). Neither VTE prophylaxis nor dysphagia/swallowing screening were considered to be done a majority of time. Secondary prevention results were variable. The respondent's level of clinical experience made the most difference in correctly answering the most appropriate IV Fluid to use in stroke patients (adjusted p=0.003) and the ideal initiation time for antithrombotic therapy (adjusted p=0.0017). Healthcare providers demonstrated a wide variability in their responses. Future efforts to improve stroke care in sub-Saharan Africa should include education and process improvement initiatives to focus on more specific aspects of stroke management based on the results from this survey.

Pulmonary function and adverse cardiovascular outcomes: Can cardiac function explain the link?

BACKGROUND: The complex interaction between pulmonary function, cardiac function and adverse cardiovascular events has only been partially described. We sought to describe the association between pulmonary function with left heart structure and function, all-cause mortality and incident cardiovascular hospitalization. METHODS: This study is a retrospective analysis of patients evaluated in a single tertiary care medical center. We used multivariable linear regression analyses to examine the relationship between FVC and FEV1 with left ventricular ejection fraction (LVEF), left ventricular internal dimension in systole and diastole (LVIDS, LVIDD) and left atrial diameter, adjusting for baseline characteristics, right ventricular function and lung hyperinflation. We also used Cox proportional hazards models to examine the relationship between FVC and FEV1 with all-cause mortality and cardiac hospitalization. RESULTS: A total of 1807 patients were included in this analysis with a median age of 61 years and 50% were female. Decreased FVC and FEV1 were both associated with decreased LVEF. In individuals with FVC less than 2.75 L, decreased FVC was associated with increased all-cause mortality after adjusting for left and right heart echocardiographic variables (hazard ratio [HR] 0.49, 95% CI 0.29, 0.82, respectively). Decreased FVC was associated with increased cardiac hospitalization after adjusting for left heart size (HR 0.80, 95% CI 0.67, 0.96), even in patients with normal LVEF (HR 0.75, 95% CI 0.57, 0.97). CONCLUSION: In a tertiary care center reduced pulmonary function was associated with adverse cardiovascular events, a relationship that is not fully explained by left heart remodeling or right heart dysfunction.
