Background: The management and follow-up of asthma patients presenting at Accident and Emergency (A&E) departments have mostly been studied in children's hospitals or specialised teaching hospitals. Aims: To study the adequacy of assessment, treatment and follow-up of patients presenting at A&E departments in non-teaching hospitals. Methods: A twenty-five per cent sample of presentations to A&E departments in all public hospitals in the Illawarra for one year was selected for a case note audit. Information on demographics, assessment, management and referral was extracted from the A&E case notes and medical records of cases with documentation of a final diagnosis of asthma. Chi square and Fischer's Exact tests were used for comparisons among hospitals. Results: Of 359 presentations with a final diagnosis of asthma, 88% were self referred and only 5% were first presentations. Objective measures of airways obstruction was not documented in 34% of admissions and 48% of nonadmissions. There was no documented follow-up in 28% of cases. The assessment and management of asthma in A&E was significantly poorer in smaller hospitals. Conclusion: Evidence of high use of A&E as a primary care facility by asthma patients was found in the study. There is a need to implement protocols to optimise assessment and treatment of asthma in smaller hospitals. (Aust NZ J Med 1993; 23: 672–677.). 相似文献

Studies have shown family planning adoption is likely to be more effective for women when men are actively involved. The transtheoretical model of behavior change was used to examine men's involvement in general contraception and intrauterine device (IUD) use by their wives. The study was carried out in rural Vietnam with 651 eligible participants. Cons of IUD use for men in precontemplation and contemplation/preparation were significantly higher than those in the action/maintenance stages, whereas the reverse was true for pros of IUD. The self-efficacy for convincing wife to have IUD in precontemplation was significantly lower than for those in higher stages. Women's education and ages, spontaneous recall of modern contraceptive method, cons for IUD, and self-efficacy for contraception and for convincing wives to get IUD inserted (or continue use) were significant predictors of men's readiness to accept IUD. Interventions are targeted to reduce cons and increase self-efficacy for IUD use. 相似文献

Validation of a measurement instrument for parental child feeding in a low and middle-income country
Digna Niken Purwaningrum Helda Yessy Maria Sibagariang Jayashree Arcot Hamam Hadi Rasita Amelia Hasnawati Risma Saski Rahmita Rohan Jayasuriya 《The international journal of behavioral nutrition and physical activity》2018,15(1):113
Background
Parental child feeding practices (PCFP) are a key factor influencing children’s dietary intake, especially in the preschool years when eating behavior is being established. Instruments to measure PCFP have been developed and validated in high-income countries with a high prevalence of childhood obesity. The aim of this study was to test the appropriateness, content, and construct validity of selected measures of PCFP in a low and middle-income country (LMIC) in which there is both undernutrition and obesity in children.Methods
An expert panel selected subscales and items from measures of PCFP that have been well-tested in high-income countries to measure both “coercive” and “structural” behaviors. Two sequential cross-sectional studies (Study 1, n =?154; Study 2, n =?238) were conducted in two provinces in Indonesia. Findings of the first study were used to refine subscales used in Study 2. An additional qualitative study tested content validity from the perspective of mothers (the intended respondents). Factorial validation and reliability were also tested. Convergent validity was tested with child nutritional status.Results
In Study 1, a confirmatory factor analysis (CFA) model with 11 factors provided good fit (RMSEA?=?0.045; CFI?=?0.95 and TLI?=?0.95) after two subscales were removed. Reliability was good among seven of the subscales. Following a decision to take out an additional subscale, the instrument was tested for factorial validity (Study 2). A CFA model with 10 subscales provided good fit (RMSEA?=?0.03; CFI?=?0.92 and TLI?=?0.90). The reliability of subscales was lower than in Study 1. Convergent validity with nutrition status was found with two subscales.Conclusions
The two studies provide evidence of acceptable psychometric properties for 10 subscales from tested instruments to measure PCFP in Indonesia. This provides the first evidence of the validity of these measures in a LMIC setting. Some shortcomings, such in the reliability of some subscales and further tests of predictive validity, require further investigation.7.

The objective of this preliminary study was to evaluate the applying of chitosan (CS)‐based microparticles (MPs) in bone regeneration in vivo. The CS MPs were fabricated using our scale‐up method, as previously described. Mesenchymal stem cells (MSC) were harvested from the femora and tibiae of Dark Agouti (DA) rats and seeded on CS MPs. An in vitro MSCs attachment experiment was conducted by trypsinizing the cells attached to the MPs at 5, 10, 20 and 30 h. Fluorescence images of MSCs attached to the MPs were taken at 24 and 48 h, using a LIVE/DEAD cell assay. The MSC/osteoblasts (OB) seeded on MPs were then cultured in vitro using osteogenic media and implanted into partial thickness bone defects in rat femurs. There were two groups of rats, including experimental animals and controls, for the in vivo studies. The experimental group were implanted with MSC‐seeded MPs and observed at 4 and 8 weeks. The control group of rats did not receive any implant material except the stainless steel plate to support the defect. Four rats per group were used for the study. The femurs were extracted at 4 and 8 weeks post‐implantation and bone formation at the defect site was analysed using radiography, microcomputed tomography (µCT) and histology. Among all groups, a significant increase in bone formation was observed in the experimental group at 8 weeks implantation. The results of this study suggested that CS MPs prove to be a successful biomaterial for bone regeneration. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

OBJECTIVE: To develop a client-generated outcome measure for use in community nursing. METHOD: Participants for the study were identified from the case load of community health nurses, from a nursing home service and from residents of a retirement village. All participants had a diagnosis of venous leg ulcer (VLU) and/or type 2 diabetes. Preliminary development of the measure involved focus groups of community clients and health professionals, and pilot testing of an existing quality of life (QoL) measure, the Patient-Generated Index. The resulting Client-Generated Index was tested for reliability and validity. RESULTS: The Pearson's correlation coefficient between administration of the CGI at T1 and T2 was 0.526 (n = 51; p = 0.0001). The CGI correlated significantly with four of eight dimensions of the SF-36, and with pain as a clinical marker for VLU r = 0.54 (p = 0.001). Overall, participants with VLU reported a lower QoL (mean CGI score 2.8) compared to those with diabetes (mean CGI score 4.1). CONCLUSIONS: The CGI was developed to measure outcomes in community health settings. Some measures of its reliability and validity are demonstrated and further research is needed to validate the instrument using other client groups. IMPLICATIONS: If routine assessment and evaluation is to contribute to measures of outcome, the instruments need to be concise and acceptable to health care providers. The CGI has all these properties. 相似文献

Fatigue and psychological disorders in chronic hepatitis C 总被引:4,自引:0,他引:4
McDonald J Jayasuriya J Bindley P Gonsalvez C Gluseska S 《Journal of gastroenterology and hepatology》2002,17(2):171-176
BACKGROUND AND AIM: Most patients with chronic hepatitis C report that they suffer from fatigue. The aim of this study was to determine if the symptom of fatigue can be a guide to indicate disease activity in chronic hepatitis C, or if it is related to psychological factors. METHODS: 115 chronic hepatitis C patients attending a liver clinic at Wollongong Hospital, Wollongong, Australia, were asked to fill out a questionnaire on the functional impact of their fatigue, and a questionnaire on psychological parameters. These were correlated with a history of intravenous drug use, alcohol history, transaminase levels and liver biopsy findings. RESULTS: Fatigue weakly correlated with the level of fibrosis on the liver biopsy, but strongly correlated with all the psychological domains of depression, anxiety, somatization, interpersonal sensitivity and hostility. CONCLUSION: The level of fatigue strongly correlated with all the psychological domains, particularly depression, and not with our measures of disease activity. 相似文献
