Pattern and frequency of neurological and neurosurgical care of adult inpatients and outpatients at a tertiary referral hospital in Kenya

Objective: To describe the patterns and burden of neurological and neurosurgical disorders at a national tertiary level referral hospital in western Kenya. Methods: We conducted a three-month period prevalence study. We recruited consecutive adult patients seeking neurological-neurosurgical care in both inpatient and outpatient settings at Moi Teaching and Referral Hospital. Results: 833 participants were included. The age range was between 19 year and 99 years (mean age = 45.3 years). The most common diagnoses among neurology inpatients were meningitis (12%), ischemic stroke (11.0%) and epilepsy/seizure (6.7%). Among neurology outpatients, epilepsy (35.1%) and ischemic stroke (18.8%) were the most common diagnoses. The most common neurosurgery inpatient diagnosis was hemorrhagic stroke (16.3%) and among outpatients, the most common diagnoses were traumatic brain injury (17.4%) and hemorrhagic stroke (16.3%). Overall, 471 (56.5%) patients underwent HIV testing, of which, 89 (18.9%) were HIV positive and 382 (81.1%) were HIV negative. Thirty-one inpatient deaths (male 58%), attributable to neurological and neurosurgical disorders, occurred during the study period. Meningitis was the most common cause of death. Conclusions: The findings suggest that meningitis, stroke, epilepsy, and traumatic brain injury were the most common diagnosis. More resources and efforts should be directed towards prevention, diagnosis and management of these conditions in the region

High prevalence of multi-drug resistant Klebsiella pneumoniae in a tertiary teaching hospital in western Kenya

Introduction: Klebsiella pneumoniae is a gram negative enterobacteriaciae commonly associated with nosocomial infections. Multidrug resistant strains are increasingly being reported with corresponding increase in morbidity and mortality. The study outlines the epidemiology and antibiotic resistance pattern of K. pneumonia over a 10 year period in Moi Teaching and Referral Hospital, Eldoret, Kenya.Methodology and Study Design: This is a retrospective analysis of all the blood culture results for K. pneumoniae isolates in the hospital for the period 2002-2013.Results: K. pneumoniae accounted for 23% of the hospital isolates (231/1356) during the study period; of these, 82.6% were from the New Born Unit. Most of the isolates were multi drug resistant with highest resistance of over 80% to Penicillins, Cephalosporins, Macrolides, Tetracyclines, Sulphonamides, Lincosamides and Chloramphenicol. Aminoglycoside and Quinolone resistance was also high at 49.2% and 41.3% respectively. The lowest resistance rates were documented for Carbapenems (23.2%). For specific antibiotics, there was high resistance to commonly used antibiotics (over 80% for Ceftriaxone, Cefipime, Gentamycin and Ceftazidime). The antibiotics with least resistance were Amikacin and Meropenem (21% and 7 % respectively).Conclusion: There was a high prevalence of multidrug resistant K. pneumoniae isolates in the hospital, the majority originated from the New Born Unit. Resistance to third generation Cephalosporins and Gentamycin was high while Meropenem and Amikacin had the least resistance.Keywords: Klebsiella pneumoniae; Antibiotic resistance; Multi drug resistance; Nosocomial infection

Stroke Mortality in Kenya’s Public Tertiary Hospitals: A Prospective Facility-Based Study

Background: Despite the increasing global burden of stroke, there are limited data on stroke from Kenya to guide in decision-making. Stroke occurrence in sub-Saharan Africa has been associated with poor health outcomes. This study sought to establish the stroke incidence density and mortality in Kenya’s leading public tertiary hospitals for purposes of informing clinical practice and policy. Methods: This is a prospective study conducted at Kenya’s leading referral hospitals, namely, Kenyatta National Hospital (KNH) and Moi Teaching and Referral Hospital (MTRH). Adult patients with confirmed cases of stroke were recruited from February 2015 to January 2016 and followed up for a minimum period of 1 year. The WHO 2006 Stroke STEPS instrument was used to collect data on incidence and mortality at days 10 and 28 and every 3 months for 24 months. The person-time of follow-up was computed from admission to death, loss to follow-up, or the end of the study. A survival regression analysis was done using the Cox proportional hazards model. Results: A total of 719 patients were recruited (KNH: n = 406 [56.5%]; MTRH: n = 313 [43.5%]). The mean age was 58.6 ± 18.7 years, and the male-to-female ratio was 1: 1.4. Ischemic stroke accounted for 56.1% of the stroke cases. The peak age for stroke was between 50 and 69 years, when 36.3% of the cases occurred. Mortality at day 10 and day 28 was 18.4 and 26.7%, respectively. The inpatient mortality rate was 21.6%. The stroke incidence density was 507 deaths per 1,000 person-years of follow-up. The mean survival time was significantly different between inpatients (13.9 months; 95% CI: 13.0–14.7) and outpatients (18.6 months; 95% CI: 17.2–19.9) (p < 0.001). A 1-year increase in age increased the hazard by 1.8%. Inpatients had a 3.9-fold increase in hazard compared to outpatients. Conclusions: Mortality due to stroke is high, with poor survival observed in the first year after stroke. The risk of death increases with increasing age and duration of hospital stay. There is need for attention to quality of care and long-term needs of stroke patients to mitigate the high mortality rates observed. Public health initiatives aimed at early screening and diagnosis should be enhanced. Further research is recommended to establish the true burden of stroke at the community level to inform appropriate mitigation measures

Disability-Adjusted Life-Years Due to Stroke in Kenya.

BACKGROUND: There is little information on stroke morbidity in Kenya to inform health care planning. The disability-adjusted life-years (DALYs) are a time-based measure of health status that incorporates both disability and mortality. METHODS: This was a multicenter prospective study in Kenya\u27s public tertiary hospitals conducted in 2015-2017. Data on sex, age, and global disability outcome were collected and used to calculate the sum of years of life lost prematurely due to stroke (YLL), the years of healthy life lost due to disability (YLD), and the DALYs. RESULTS: Up to 719 adult stroke patients participated in the study. The peak age group for stroke was 60-64 years, with ischemic stroke accounting for 56.1% of the stroke cases. After 1-year follow-up, the YLD were 2,402.50, YLL were 5,335.99, and the DALYs were 7,738.49. YLD contributed 31% of the total DALYs. The DALYs varied by sex (male: 2,835.79; female: 4,902.70 years) and by stroke type (ischemic stroke: 4,652.98; hemorrhagic stroke: 3,085.51). The young age group (\u3c 45 years) bore a greater burden accounting for 35.6% of the total DALYs. CONCLUSION: The YLD, YLL, and DALYs observed reinforce the need for targeted prevention of risk factors and comprehensive stroke care initiatives in Kenya

Stroke distribution patterns and characteristics in Kenya\u27s leading public health tertiary institutions: Kenyatta National Hospital and Moi Teaching and Referral Hospital.

BACKGROUND: Cardiovascular diseases are the second leading cause of morbidity and mortality in Kenya. However, there is limited clinic-epidemiological data on stroke to inform decision making. This study sought to establish stroke distribution patterns and characteristics in patients seeking care at Kenyatta National Hospital (KNH) and Moi Teaching and Referral Hospital (MTRH), with the ultimate aim of establishing the first national stroke registry in Kenya. METHODS: This was a prospective multicentre cohort study among stroke patients. The study used a modified World Health Organisation STEP-wise approach to stroke surveillance tool in collecting data on incidence, major risk factors and mortality rate. The Cochran\u27s Mantel-Haenszel chisquared test of conditional independence was used with p-value set at 0.05. RESULTS: A total of 691 patients with confirmed stroke were recruited [KNH 406 (males: 40.9%; females: 59.1%); MTRH 285 (males: 44.6%; females: 55.4%) ] and followed over a 12-month period. Overall, ischaemic stroke accounted for 55.6% of the stroke cases, with women being the most affected (57.5%). Mortality rate at day 10 was 18.0% at KNH and 15.5% at MTRH, and higher in the haemorrhagic cases (20.3%). The most common vascular risk factors were hypertension at 77.3% (males: 75.7%; females: 78.5%), smoking at 16.1% (males: 26.6% females: 8.3%) and diabetes at 14.9% (males: 15.7%; females: 14.4%). Ischaemic stroke was conditionally independent of gender after adjusting for age. CONCLUSION: To our knowledge this is the first pilot demonstration establishing a stroke registry in sub-Saharan Africa and clearly establishes feasibility for this approach. It also has utility to both inform and potentially guide public policy and public health measures on stroke in Kenya. Important and unexpected observations included the preponderance of women affected by cerebrovascular disease and that cigarette smoking was the second most common risk factor. The latter, over time, will further impact on the clinico-epidemiological profile of cerebrovascular disease in Kenya
