BACKGROUND AND AIMS: In South Africa diabetes makes a significant contribution to the burden of disease. Diabetic retinopathy is a leading cause of adult blindness, and screening can reduce the incidence. This project aimed to implement and evaluate a new service for retinal screening that uses a non-mydriatic mobile fundal camera in primary care. This is the first time such a service has been evaluated in an African primary care context. METHODS: The service was implemented as an operational research study at three community health centres and data were collected to evaluate the operational issues, screening, reporting and referral of patients. RESULTS: Out of 400 patients screened 84% had a significantly reduced visual acuity, 63% had retinopathy (22% severe nonproliferative, 6% proliferative and 15% maculopathy), 2% of eyes could not be screened and 14% of patients required dilatation. Referral was necessary in 27% of cases for cataracts, in 7% for laser treatment and in 4% for other specialist services. Repeat photography was needed in 8% and urgent follow-up in 12%. A SWOT analysis of the pilot project was completed and recommendations were made on how to integrate it into the district health system. CONCLUSION: Screening with a fundal camera improved the quality of care for diabetic patients and is feasible in the South African public sector, primary care setting. A single technician should be able to photograph almost 10,000 patients a year. 相似文献

Salmonella enterica serotype Typhimurium is a common cause of salmonellosis among humans and animals in England, Wales, and Northern Ireland. Phage types DT104 and U302 were the most prevalent types in both livestock and humans in 2001. In addition, Salmonella serotype Typhimurium DT204b was responsible for a recent international outbreak involving England. A total of 119 isolates from humans (n = 28) and animals or their environment (n = 91), belonging to DT104 (n = 66), U302 (n = 33), DT204b (n = 12), and DT49 (n = 8), were fingerprinted by a combination of well-established genetic methods (pulsed-field gel electrophoresis [PFGE], PstI/SphI [PS] ribotyping, and plasmid profiling). The different techniques identified different degrees of polymorphism (from greatest to least, plasmid profiling [40 types], PS ribotyping [34 types], and PFGE [23 types]). It seems clear that a prevalent genomic clone, as well as a variety of less frequent clones, is present for each of the phage types. In most cases, the prevalent clones appeared within isolates from several animal species and from several geographical locations. We did not find clear evidence of a higher degree of diversity for any of the animal species included, or of any link between isolates from particular animal species and humans. The data presented show the inaccuracy of drawing epidemiological conclusions based on a single fingerprinting method. Strains that share one of the markers do not necessarily belong to the same clone, and a multiple typing approach is required to enable enough discrimination to track strains for epidemiological investigations. 相似文献

Lecturer feedback on students' essays is important to the quality of the experience students have at university (Norton & Norton, 2001). The aim of the present study was to investigate whether early childhood students at one university actually read lecturer feedback on their essays and, if they did, what they found helpful and not helpful to their learning. Feedback was defined as 'giving students information on how well or how poorly they are doing in their academic work' (Hounsell, 1987, p. 109). Using the Vygotskian concept of learning as a socially shared activity, qualitative data were collected from second-year students from a four-year early childhood degree programme via an anonymous survey and four focus groups. Major findings were that, in contrast with studies of students in other programmes, early childhood students read lecturer feedback on their essays and used feedback that was detailed and explanatory as a learning tool. Types of feedback students found to be most and least useful were identified. 相似文献

Personal and professional values of healthcare practitioners influence their clinical decisions. Understanding these values for individuals and across healthcare professions can help improve patient-centred decision-making by individual practitioners and interprofessional teams, respectively. We aimed to identify these values and integrate them into a single framework using Schwartz’s values model. We searched Medline, Embase, PsycINFO, CINAHL and ERIC databases for articles on personal and professional values of healthcare practitioners and students. We extracted values from included papers and synthesized them into a single framework using Schwartz’s values model. We summarised the framework within the context of healthcare practice. We identified 128 values from 50 included articles from doctors, nurses and allied health professionals. A new framework for the identified values established the following broad healthcare practitioner values, corresponding to Schwartz values (in parentheses): authority (power); capability (achievement); pleasure (hedonism); intellectual stimulation (stimulation); critical-thinking (self-direction); equality (universalism); altruism (benevolence); morality (tradition); professionalism (conformity); safety (security) and spirituality (spirituality). The most prominent values identified were altruism, equality and capability. This review identified a comprehensive set of personal and professional values of healthcare practitioners. We integrated these into a single framework derived from Schwartz’s values model. This framework can be used to assess personal and professional values of healthcare practitioners across professional groups, and can help improve practitioners’ awareness of their values so they can negotiate more patient-centred decisions. A common values framework across professional groups can support shared education strategies on values and help improve interprofessional teamwork and decision-making. 相似文献

Aim: Most national guidelines recommend psychological therapy for people with first‐episode psychosis (FEP) but interventions proven effective in randomized control trials (RCTs) conducted in research settings do not always translate effectively to real‐world clinical environments. In a limited health system, it is important to understand the system and patient barriers to participation in effective treatment. We sought to determine what patient characteristics influenced clinicians' decision to refer or not to refer to group cognitive behavioural therapy for FEP and what characteristics were associated with those referred attending/not attending and adhering/not adhering to the programme. Methods: Between 2006 and 2008, all cases of confirmed FEP from a defined geographical region were examined using the Structured Clinical Interview for DSM‐IV‐TR Axis I Disorders for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV) diagnoses, the Scale for Assessment of Positive Symptoms, Scale for Assessment of Negative Symptoms, Calgary Depression Scale for Schizophrenia and Birchwood Insight Scale. Duration of untreated psychosis was established using the Beiser Scale. Results: Of the 124 (77 males, 47 females) people in the final sample, 88 (72%) were referred for cognitive behavioural therapy (CBT), 52 (59%) attended and 12 (23%) did not complete CBT. Those with higher levels of insight into the need for treatment (U = 740.00, z = −2.63, P = 0.008) and higher levels of positive symptoms (t (120) = −3.064, P = 0.003) were more likely to be referred to CBT. Those with higher educational attainment (χ2 = 9.48, P = 0.03) and fewer negative symptoms, particularly in relation to global attention (t (85) = 2.32, P = 0.03), were more likely to attend and complete CBT. Conclusion: Within an early intervention service for FEP, it appears that individuals with less education, more negative symptoms and less insight experienced significant barriers to successfully completing group CBT. More information for referring clinicians about the benefits of CBT for FEP could help increase referral rates. Assertive outreach for people at risk of disengaging or non‐adherence should also be considered. 相似文献

OBJECTIVE:: To determine predictors of fistula repair outcomes 3 months postsurgery. METHODS:: We conducted a multicountry prospective cohort study between 2007 and 2010. Outcomes, measured 3 months postsurgery, included fistula closure and residual incontinence in women with a closed fistula. Potential predictors included patient and fistula characteristics and context of repair. Multivariable generalized estimating equation models were used to generate adjusted risk ratios (RRs) and 95% confidence intervals (CIs). RESULTS:: Women who returned for follow-up 3-month postsurgery were included in predictors of closure analyses (n=1,274). Small bladder size (adjusted RR 1.57, 95% CI 1.39-1.79), prior repair (adjusted RR 1.40, 95% CI 1.11-1.76), severe vaginal scarring (adjusted RR 1.56, 95% CI 1.20-2.04), partial urethral involvement (adjusted RR 1.36, 95% CI 1.11-1.66), and complete urethral destruction or circumferential defect (adjusted RR 1.72, 95% CI 1.33-2.23) predicted failed fistula closure. Women with a closed fistula at 3-month follow-up were included in predictors of residual incontinence analyses (n=1,041). Prior repair (adjusted RR 1.37, 95% CI 1.13-1.65), severe vaginal scarring (adjusted RR 1.35, 95% CI 1.10-1.67), partial urethral involvement (adjusted RR 1.78, 95% CI 1.27-2.48), and complete urethral destruction or circumferential defect (adjusted RR 2.06, 95% CI 1.51-2.81) were significantly associated with residual incontinence. CONCLUSION:: The prognosis for genital fistula closure is related to preoperative bladder size, previous repair, vaginal scarring, and urethral involvement. LEVEL OF EVIDENCE:: II. 相似文献
