Attitude and perceived barriers by emergency department staff towards routine HIV testing in the emergency department of three academic centres

Michael, Mojeed Oluwaseyi 25 March 2014 (has links)
The South African HIV testing guideline, Center for Disease Prevention and Control (CDC), World Health Organisation (WHO), and Joint United Nations Programme on HIV/AIDS (UNSAID) have recommended that routine HIV testing be offered in every healthcare facility. The emergency department(ED) is uniquely placed to be involved in this initiative due the volumes and characteristics of patients seen in the ED. This study seeks to determine the attitude of ED staff and their perceived barriers towards routine testing in the ED. Methods: Paper-based questionnaires were distributed to 170 members of ED staff in 3 academic hospitals. Survey Questionnaires contained 25 questions to reflect staff knowledge of HIV infection, their attitude towards testing, current testing practices and perceived barriers to testing. Chi square test was used to test for associations between various variables and the willingness to test. Result: Response rate was 52% (88/170). Average year of experience in an ED (SD) was 4.4 years. Only 30% of ED staff favoured routine testing in the ED. However, 63% of staff was willing to test if result was available within 20 minutes. Members of ED staff generally prefer that a HIV counsellor disclose the result of a positive test. Members of the white race and those who identified fewer barriers were more likely to test. Important barriers cited include; time constraints (77%), inadequate resources (77%), and lack of support staff (71%). Conclusion: The ED staff generally favoured risk based testing over routine testing. Members of the ED staff are generally willing to offer routine HIV testing, but the presence of barriers may limit the implementation of routine HIV testing in the ED.

Gearbox Diagnosis

Bengtsson, Jonas January 2011 (has links)
Diagnosis based on vibration analysis is a method that has many benefits to offer. It is easy to implement the method on existing transmissions by attaching accelerometers outside the gearbox housing. If you have knowledge of the gearbox geometry, such as number of tooth on the gears and types of bearings, and any unwanted frequencies can be filtered out a good estimation of the gearbox condition can be achieved. In this thesis a number of condition indicators have been tested to identify and isolate different faults that may appear. All analysing have been done in the time domain on different synchronously averaged signals. The condition indicators have been used together with diagnosis theory from the division of Vehicular systems to create a diagnosis system able to find faults on a number of modelled signals.

Detection of clinically silent alpha-globin gene mutations in Chinese using high resolution melting analysis

Ho, Sophia KW, 何廣慧 January 2014 (has links)
α-thalassemia is an inherited globin gene disorder commonly found among the Chinese population. It is composed of both non-deletional and deletional α-globin gene mutations. Classical α-thalassemia presents with red cell microcytosis but silent cases with a normal mean corpuscular volume (MCV) are also seen. Routine laboratory testing methods for large-scale detection of silent α-thalassemia mutations are onerous and time-consuming. Furthermore, methods such as denaturing high performance liquid chromatography (HPLC) or denaturing gradient gel electrophoresis (DGGE) for scanning of point mutations are costly and they require post-PCR separation. High resolution melting (HRM) analysis is an economical, sensitive, and fast method for large scale point mutation scanning. Contamination is significantly reduced with HRM because the process is performed in a closed-tube environment and does not require post-PCR manipulation. We used HRM and multiplex gap-PCR analysis to determine the prevalence of silent α-thalassemia carriers in Hong Kong. Of the 223 hematologically normal blood samples scanned by Roche LightCycler 480®, HRM did not show any sample with a non-deletional α-globin gene mutation of clinical significance. α-multiplex gap-PCR analysis revealed 36 samples (16.1%) with single α-globin gene deletions. The detection of single α-globin gene deletions in samples with a MCV greater than 80 fL indicates that the previously reported prevalence of α-thalassemia mutations in our Chinese population based on MCV screening is under-estimated. The data also suggest that non-deletional α-thalassemia mutations presenting with a normal MCV are very rare, and they most likely present with microcytosis. The fact that most silent α-thalassemia mutations are due to large deletions supports the use of traditional molecular techniques such as gap-PCR for their detection. HRM can be used as an adjunct tool for large-scale population screening of non-deletional mutations. This study provides more accurate data on the prevalence of silent α-thalassemia carriers in the Hong Kong Chinese population. The information will facilitate genetic counseling and risk assessment in families carrying α-thalassemia mutations. / published_or_final_version / Pathology / Master / Master of Medical Sciences

Exploring the symptom dimensions as documented in case record of patients with first episode psychosis at the first interview in the early assessment service for young people with psychosis (EASY) clinic

Luk, Yun-kin, 陸潤健 January 2014 (has links)
Objectives Severe mental illness is a debilitating condition affecting a wide range of functioning of an individual. Identification of signs and symptoms is part of clinical assessment which aids case formulation, making diagnosis, determine treatment planning and outcome. How the symptoms are documented in case record undoubtedly affect the decision and communication among mental health professionals, treatment protocol, potential outcome and prognosis. This is the first study in Hong Kong mental health service to overview the symptom dimensions documented by clinicians in case records. Currently, there is no clinical practice guideline to guide clinicians on symptom documentation. This study attempts to explore the symptom dimensions as documented in the first interview records of people with first episode psychosis in EASY clinic in a local hospital. The result will serve as preliminary reference material or the development of an appropriate documentation guideline or audit in future. Method A retrospective review of case records was conducted to evaluate the symptom documentation by clinicians. All first interview notes of patients suffering from schizophrenia spectrum disorder who attended the EASY clinic in 2012 were included.90 case records were identified. The symptoms characteristics were recorded into a template and categorized with reference to the domains of psychopathology in DSM-5, SAPS and SANS. A total of 29 items of symptom characteristics and related clinical features were identified and measured with descriptive statistics. Results All symptom characteristics and clinical features were reported in percentage. It was found that majority of interview notes(62%)had documented a range of 22-26items out of 29 items(76-90%) of symptom characteristics and clinical features observed from case records. Clinicians had demonstrated high proficiency in documenting a comprehensive range of psychiatric symptoms. Conclusion This paper aims to increase the awareness of clinicians on continuous evaluation of current practice on symptom documentation; to identify good practice or area for improvement; and initiate the development of standardized documentation guideline to guide future symptom documentation practice for betterment of quality patient care and service planning for people with first episode psychosis. / published_or_final_version / Psychological Medicine / Master / Master of Psychological Medicine
