Making clinical decisions for dental care: concepts to consider

Clinical decisions are often made with incomplete information, yet patient care decisions are made every day. Patients vary clinically, uncertainty exists in diagnostic and prognostic information, and many preventive and treatment alternatives have not been formally assessed for their effectiveness. Because scientific information will never answer all clinical questions, clinical decisions are partially based on probabilistic information.
This paper describes how to apply clinical decision making to diagnosing and managing dental caries and periodontal diseases. By using explicit information to quantify probabilities and outcomes, clinical decision making analyzes decisions made under uncertain conditions and the uncertain impact of clinical information.
Clinical decision making incorporates concepts for preventing, diagnosing and treating dental caries and periodontal diseases: risk assessment, evidence-based dentistry, and multiple oral health outcomes. This information can serve as a tool for clinicians to augment clinical judgment and expertise.

Differences in plans for living at home between temporary residents of a health-care facility for the elderly and their family caregivers in Japan

Aim: Older residents in Japan requiring rehabilitation often reside in health‐care facilities for the elderly (HCFE) prior to being discharged to home. The return home can be very stressful for both the elder and family caregiver. The purpose of this study was to clarify the differences in plans for home life between the residents of a HCFE who were scheduled for discharge home and their family caregivers. Method: Semistructured interviews were conducted with eight pairs of elders and caregivers. Results: Differences were seen in several areas, including dietary preferences, recognition of the elder’s independence, preconceptions or not knowing about the elder’s pleasurable activities, and the way of care. Conclusions: Differences with regard to enjoyable activities for the elderly arose from a lack of understanding of the lives of the elderly on the part of their families.     

设立门诊健康教育室需求的调查与分析

且的调查和分析门诊设立健康教育室的可能性与必要性，使门诊健康教育工作变得更规范．更系统。更科学、更有效，更经济。方法采用发放问卷的形式，随机对2004年1月-2006年1月在上海市桌三级综合性医院门诊就诊的200例病人进行不记名调查、统计和分析．结果病人在门诊就诊时普遍认为健康教育现状不够理想，而对健康教育需求较迫切，对于开设健康教育室十分受欢迎。结论门诊设立健康教育室可将现有的医院内存在的、分散的、不同形式的健康教育工作纳入一个集中、统一的部门，有利于提高门诊健康教育质量。

职业性萘暴露工人的健康监护结果评价

目的：讨论萘对人体的慢性毒效应和亚临床客观检测指标。方法：对河南省萘暴露工人（环境接触萘浓度平均为８．２５～２６．４３ｍｇ／ｍ３）进行了健康监护和医学动态观察。结果：发现长期萘暴露工人的白细胞、血小板减少及眼晶体混浊检出率显著高于对照组（Ｐ＜０．００１）；血清ＳＯＤ同功酶、ＧＳＨ－ＰＸ活性显著低于对照组，而ＬＰＯ水平、神经元特异性烯醇化酶（ＮＳＥ）活性水平以及外周血染色体畸变和微核阳性检出率均显著高于对照组（Ｐ＜０．００１）。神经行为功能检查结果，主要为消极情绪增加，记忆力下降等。事件相关电位Ｐ３００峰潜伏期比对照组显著延长，与对照组差异显著（Ｐ＜０．０５）。结论：慢性低浓度萘暴露对工人主要损害部位（靶器官）有皮肤，眼、血液和神经组织等。ＮＣＴＢ、ＮＳＥ、Ｐ３００三项可作为早期神经受损的客观指标。     

Patient readiness for return to home: Discord between expectations and reality

This study examined the interface between acute hospital care and return to home in relation to elderly patients' perceived ability and preparedness to cope at home. Seventy-six (n = 76) elderly patients aged 60 years and over were randomly recruited from a large Queensland hospital and interviewed prior to discharge about their perceived health, functional status and their ‘readiness’ to cope at home. They were followed up at home 7–10 days post-discharge. Comparisons were made between a number of measures at discharge and post-discharge. Although the majority of patients indicated that they would cope very well upon discharge, a large number of patients reported experiencing considerable difficulty with activities of daily living, particularly instrumental activities of daily living prior to and especially after discharge. The self-reported health status of patients similarly deteriorated between discharge and follow-up. Despite a large number of patients experiencing functional limitations, few were referred to hospital or community-based therapy services. Some policy implications are explored.

Comparison of gas-liquid chromatography and EMIT assay for serum valproic acid

We describe a simple direct extraction method for the gas-liquid chromatography determination of serum valproic acid. The working range for the assay is 2-180 mg/L and our within-run precision was 5.8 and 4.3% at the 40 and 90 mg/L concentrations respectively. Hemolyzed and lipemic sera as well as samples from patients with hyperbilirubinemia and from patients with decreased renal function were put through the assay and no interfering peaks were noted. Interference occurred when teflon-lined screw caps were used during the extraction step. The method was proven to be accurate by linear regression analysis of samples containing weighed-in amounts of valproic acid. The above assay was compared to an enzyme immunoassay technique (EMIT). The working range for the latter is 10-150 mg/L and the with-run precision was 10.8 and 5.9% and 90 mg/L concentration respectively. Samples were run by both the gas-liquid chromatograph and enzyme immunoassay methods and gave very similar results over the range 16-139 mg/L.     

Action Research: a valuable research technique for service delivery development

The evaluation of healthcare practice and service delivery is fraught with difficulties. Service development and / or delivery occurs within socially dynamic settings which are in a continual state of change. Service development also often involves large elements of improvisation. The action research approach is useful for health service research, as it supports collaboration between researchers and practitioners, and not only allows but makes explicit that the action researcher has both roles within the setting being studied. This paper discusses action research methodology and offers insight into principles that favor its use for service delivery development. This includes consideration of the interactive variables within studies of health care systems and the importance of evaluating relationships between stakeholders to understand how these factors or variables, which cannot be controlled for, are responsible for successful development of the service. Action research facilitates change and helps bridge the heory--practice gap. With the current dynamic changes within both the pharmacy profession and national health services, researchers may find the action research technique of value when considering new roles and innovative ways of engaging in collaborative, multi-disciplinary working to improve delivery of patient care.Accepted july 2004
