BackgroundAs knee osteotomy surgery becomes increasingly accessible, more patients may turn to the Internet for information. This study examined the source, quality, content and readability of online information regarding osteotomy around the knee.MethodsThe first 70 websites returned by the top four search engines were identified using the key words: “knee osteotomy” and “high tibial osteotomy.” The websites were categorised by type and assessed using the DISCERN score, Journal of the American Medical Association (JAMA) benchmark criteria and a novel Knee Osteotomy-Specific Score (KOSS). The presence of the Health On the Net (HON) code accreditation seal was noted. Readability of each website was assessed using eight readability formulae. The mean reading grade level (RGL) was compared to the 6th and 8th grade reading levels. The mean RGL of each category was also compared.ResultsOf the 45 unique websites analysed, the majority were Physician (33%) and Journal websites (31%). The mean DISCERN score was 36.7 (±8.9) which is classified as ‘poor.’ The mean JAMA benchmark criteria score was 2.04 (±1.5) and Physician websites were most likely to be scored zero. The mean KOSS was 15.4 (±5.7). The highest scoring website was a Commercial site but, overall, Journal category sites provided the best quality information. Websites that bore the HONcode seal obtained higher DISCERN, JAMA benchmark criteria and Knee Osteotomy - Specific Scores.The cumulative mean RGL was 13.2 (±2.2) which exceeded the 6th grade level by an average of 7.2 grade levels and the 8th grade level by an average of 5.2 grade levels. No website (0%) was written at or below either the 6th or the 8th grade reading levels. The mean Flesch Reading Ease Score of all websites was 41.13 (±14.7) which is classified as ‘difficult.’ Journal websites had the highest RGL.ConclusionThe information available online regarding osteotomy around the knee varies tremendously in quality and completeness. Physician sites predominate, but these were among the lowest scoring of all websites. Even where high quality information is available, it is set at too high a level to be easily understood.Level of evidenceSurvey of materials – Internet.  相似文献

Background

Currently, there is renewed interest in the role community participation can play in Primary Health Care (PHC) programmes such as the delivery of effective anti-TB treatment to patients in high-burden settings.

Objectives

To explore the feasibility of community participation in a high-burden Tuberculosis Control Programme and to establish how supervision of treatment by lay volunteers compares with other methods of tuberculosis treatment delivery in the Northern Cape province of South Africa.

Methods

Prospective study involving 769 patients with confirmed pulmonary TB who were followed-up over a one-year period. Questionnaire interviews were also carried out with 135 lay volunteers participating in the TB programme.

Results

One-third of the TB patients in the study received their treatment from lay volunteers in the community. Treatment outcomes for new patients supervised from the community were found to be equivalent to those who received treatment through other modes of treatment delivery (RR=1.04[0.94–1.16], p=0.435). For the re-treatment patients, community-based treatment was found to be superior (RR=5.89[2.30–15.09], p<0.001), to self-administered therapy.

Conclusions

Health care planners should consider community participation as a viable way of ensuring accessibility and effectiveness in PHC programmes. There is need for more research into ways of achieving sustainability in resource-limited but high disease burden settings.  相似文献

Introduction

Total Lymphocyte Count (TLC) has been found to be an inexpensive and useful marker for staging disease, predicting progression to AIDS and death and monitoring response to ART. However, the correlation between TLC and CD4 has not been consistent. Access to HAART is expanding in Kampala, Uganda, yet there are no published data evaluating the utility of TLC as inexpensive surrogate marker of CD4 cell count to help guide therapeutic decisions.

Objective

To evaluate clinical illnesses and total lymphocyte count (TLC) as surrogate markers of the CD4 cell count in HIV infected persons being considered for ART.

Methods

A total of 131 patients were enrolled and evaluated by clinical assessment, TLC and CD4 count. Clinical illnesses and TLC dichotomized at various cut-point values were used to determine the sensitivity, specificity, and positive and negative predictive values (PPV and NPV) for the diagnosis of CD4 count <200 cells/mm3 among 100 participants fulfilling criteria for WHO clinical stage 2 and 3.

Results

A strong correlation was observed between TLC and CD4 (r = 0.73, p<0.0001). For all clinical syndromes, except pulmonary tuberculosis, the positive predictive values (PPV) for a CD4 count <200 cells/mm3 were high (>80%) but the negative predictive values (NPV) were low. Using the WHO recommended TLC cut-off of 1200 cells/mm3 to diagnose a CD4 less than 200 cells/mm3, the PPV was 100%, and the NPV was 32%.

Conclusion

Our data showed a good correlation between TLC and CD4 cell count. However, the WHO recommended TLC cutoff of 1200 did not identify the majority of WHO stage 2 and 3 patients with CD4 counts less than 200 cells/mm3. A more rational use of TLC counts is to treat all patients with WHO stage 2 and 3 who have a TLC <1200 and to limit CD4 counts to patients who are symptomatic but have TLC of >1200.  相似文献

目的:分析江苏省护理院卫生资源配置现状与效率,并提出完善对策。方法:应用描述性统计方法分析2013~2019年护理院卫生资源配置和利用情况,采用数据包络分析法评价卫生资源投入产出效率,采取TOPSIS法综合评估床位利用效率。结果:2019年江苏省护理院为246家,其中71.95%集中在城市地区;2019年护理院床位数为38274张,床位医生比和床位护士比分别为1:0.06和1:0.18,床位使用率为72.32%,平均住院天数比2013年缩短20.5天。数据包络分析结果显示,2016~2018年综合技术效率值均为1.0,2019年为0.990。TOPSIS法评估结果显示,2013~2017年床位利用效率逐年上升,2018和2019年有所下降。结论:护理院城乡分布不均衡,人员配置不足,近年来投入产出效率为相对有效或弱有效,但床位总体利用率偏低。今后合理规划设置护理机构,增加人力资源配置,提升护理院服务质量,最大限度发挥护理院卫生资源的作用。  相似文献
