The free healthcare initiative in Sierra Leone: Evaluating a health system reform, 2010‐2015 下载免费PDF全文
Sophie Witter Nouria Brikci Tim Harris Richard Williams Sarah Keen Ana Mujica Alex Jones Alex Murray‐Zmijewski Barbara Bale Bailah Leigh Ade Renner 《The International journal of health planning and management》2018,33(2):434-448
This article presents the findings of a theory‐based evaluation of the Sierra Leone Free Health Care Initiative (FHCI), using mixed methods. Analytical approaches included time‐series analysis of national survey data to examine mortality and morbidity trends, as well as modelling of impact using the Lives Saved Tool and expenditure trend analysis. We find that the FHCI responded to a clear need in Sierra Leone, was well designed to bring about needed changes in the health system to deliver services to the target beneficiaries, and did indeed bring funds and momentum to produce important systemic reforms. However, its ambition was also a risk, and weaknesses in implementation have been evident in a number of core areas, such as drugs supply. We conclude that the FHCI was one important factor contributing to improvements in coverage and equity of coverage of essential services for mothers and children. Modelled cost‐effectiveness is high—in the region of US$ 420 to US$ 444 per life year saved. The findings suggest that even—or perhaps especially—in a weak health system, a reform‐like fee removal, if tackled in a systematic way, can bring about important health system gains that benefit vulnerable groups in particular. 相似文献

BACKGROUND: Cold hemagglutinins are generally immunoglobulin M (IgM) kappa antibodies reactive at temperatures below 37 degrees C and if of high titer may cause hemolysis. Platelet (PLT) cold agglutinins (CAs) are rare and poorly characterized. A detailed molecular characterization of the variable domains of a pathologic, PLT-reactive, CA is presented. CASE REPORT: A 70-year-old woman was admitted with rectal bleeding accompanied by widespread petechiae, bruising, tongue and buccal mucosa bleeding, and epistaxes and proved refractory to HLA- and HPA-matched PLTs. Detailed investigation showed monoclonal heavy-chain gene rearrangement with an IgM paraprotein of 3.3 g per L and a trace of kappa Bence Jones protein in the urine, compatible with a diagnosis of secretory B-cell non-Hodgkin's lymphoma (B-NHL). PLT antibody (PAIg) investigations revealed a potent IgM kappa PLT CA. Sequencing of the rearranged variable domain genes of the malignant clone together with idiotype-specific antibodies obtained by DNA-based immunization of rabbits and matrix-assisted laser desorption/ionization-time-of-flight analysis of the PAIgM provided a irrefutable link between the thrombocytopenia, the IgM paraprotein, and the PAIgM against alphaIIbbeta3. The thrombocytopenia and bleeding were refractory to standard treatment and PLT transfusion, but treatment with rituximab resulted in a recovery of the PLT count and a complete remission of B-NHL. CONCLUSION: The IgM kappa paraprotein derived from the malignant B-cell clone was a potent and clinically significant CA against alphaIIbbeta3. The testing for PLT CAs in patients with a paraprotein and refractory to matched PLTs may aid the selection of appropriate treatment. 相似文献

Patient-initiated device removal in intensive care units: a national prevalence study 总被引:2,自引:0,他引:2

OBJECTIVE: Information is needed about patient-initiated device removal to guide quality initiatives addressing regulations aimed at minimizing physical restraint use. Research objectives were to determine the prevalence of device removal, describe patient contexts, examine unit-level adjusted risk factors, and describe consequences. DESIGN: Prospective prevalence. SETTING: Total of 49 adult intensive care units (ICUs) from a random sample of 39 hospitals in five states. METHODS: Data were collected daily for 49,482 patient-days by trained nurses and included unit census, ventilator days, restraint days, and days accounted for by men and by elderly. For each device removal episode, data were collected on demographic and clinical variables. RESULTS: Patients removed 1,623 devices on 1,097 occasions: overall rate, 22.1 episodes/1000 patient-days; range, 0-102.4. Surgical ICUs had lower rates (16.1 episodes) than general (23.6 episodes) and medical (23.4 episodes) ICUs. ICUs with fewer resources had fewer all-type device removal relative to ICUs with greater resources (relative risk, 0.76; 95% confidence interval, 0.66-0.87) but higher self-extubation rates (relative risk, 1.27; 95% confidence interval, 1.07-1.52). Men accounted for 57% of the episodes, 44% were restrained at the time, and 30% had not received any sedation, narcotic, or psychotropic drug in the previous 24 hrs. There was no association between rates of device removal with restraint rates, proportion of men, or elderly. Self-extubation rates were inversely associated with ventilator days (rs = -0.31, p = .03). Patient harm occurred in 250 (23%) episodes; ten incurred major harm. No deaths occurred. Reinsertion rates varied by device: 23.5% of surgical drains to 88.9% of monitor leads. Additional resources (e.g., radiography) were used in 58% of the episodes. CONCLUSION: Device removal by ICU patients is common, resulting in harm in one fourth of patients and significant resource expenditure. Further examination of patient-, unit-, and practitioner-level variables may help explain variation in rates and provide direction for further targeted interventions. 相似文献

Group II metabotropic glutamate (mGlu) receptor agonists, including (1S,2S,5R,6S)-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylate monohydrate (LY354740) and (-)-2-oxa-4-aminobicyclo[3.1.0]hexane-4,6-dicarboxylate (LY379268), have demonstrated efficacy in animal models of anxiety and schizophrenia, and LY354740 decreased anxiety in human subjects. Herein, we report the in vitro pharmacological profile and pharmacokinetic properties of another potent, selective, and structurally novel mGlu2/3 receptor agonist, (-)-(1R,4S,5S,6S)-4-amino-2-sulfonylbicyclo[3.1.0]hexane-4,6-dicarboxylic acid (LY404039) and provide comparisons with LY354740. Similar to LY354740, LY404039 is a nanomolar potent agonist at recombinant human mGlu2 and mGlu3 receptors (K(i) = 149 and 92, respectively) and in rat neurons expressing native mGlu2/3 receptors (Ki = 88). LY404039 is highly selective for mGlu2/3 receptors, showing more than 100-fold selectivity for these receptors, versus ionotropic glutamate receptors, glutamate transporters, and other receptors targeted by known anxiolytic and antipsychotic medications. Functionally, LY404039 potently inhibited forskolin-stimulated cAMP formation in cells expressing human mGlu2 and mGlu3 receptors. Electrophysiological studies indicated that LY404039 suppressed electrically evoked excitatory activity in the striatum, and serotonin-induced l-glutamate release in the prefrontal cortex; effects reversed by LY341495. These characteristics suggest LY404039 modulates glutamatergic activity in limbic and forebrain areas relevant to psychiatric disorders; and that, similar to LY354740, it works through a mechanism that may be devoid of negative side effects associated with current antipsychotics and anxiolytics. Interestingly, despite the slightly lower potency (approximately 2-5-fold) of LY404039 versus LY354740 in binding, functional, and electrophysiological assays, LY404039 demonstrated higher plasma exposure and better oral bioavailability in pharmacokinetic experiments. Collectively, the current data indicate that LY404039 may be valuable in the treatment of neuropsychiatric disorders, including anxiety and psychosis. 相似文献

AIM: This paper is a report of a literature review of the determinants of health and health behaviour relevant to coronary heart disease risk for women living on a low income. BACKGROUND: Coronary heart disease is now recognized as the biggest killer of women in both developed and developing countries. As in men, women's mortality rates for coronary heart disease seem to be directly related to income inequality and social deprivation. METHOD: The Medline, British Nursing Index, CINAHL, Cochrane Library, Psychinfo and Web of Science databases were searched from 1996 to 2006 using the search terms 'women and CHD risk', 'women and health behaviour', 'women low income and health behaviour', 'women low income and smoking', 'women low income and diet' and 'women low income and exercise'. In relation to the wider determinants of health 'women low income and CHD', 'women education and CHD', 'women employment and CHD' and 'women housing and CHD'. Seminal research reports before this period were included if they proved highly influential on later research. A narrative review was conducted. FINDINGS: All the wider determinants of health considered had a negative impact on heart disease risk for women living on low incomes. The latter also appears to have a negative impact on health behaviour. CONCLUSION: Although the impact of the wider determinants of health on coronary heart disease risk are well-understood, their impact on health behaviour (specifically diet, exercise and smoking) is less well-understood. If effective interventions are to be designed to tackle inequalities in health, then this deficiency needs to be addressed urgently. 相似文献

Efforts to promote safe care prompted the development point-of-care technology, but successful adoption requires acceptance by nursing staff. To assess the satisfaction of nurses who use point-of-care technology that integrates nurse scanning of bar-coded medications with the patient's electronic medication administration record, the authors examined nurses' satisfaction with barcode/electronic medication administration record before and after introduction in an academic medical center. 相似文献
