Concepts of health and disease and caries prediction: a literature review

Abstract— Biomedical determinants of dental caries have been more extensively investigated than psychosocial factors and their impact on caries prevalence and incidence seems to be greater. However, a majority of these investigations relate to children and adolescents. An implementation of social and psychologic variables may be more relevant regarding dental caries in adults. In addition, a multidisciplinary approach might improve our understanding of dental caries as a multifactorial disease and bridge the gap between a biomedical concept and a more holistic approach to dental health.     

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     

The 5-Step family intervention in primary care: II. The views of primary healthcare professionals

Background: This is the second of two papers using qualitative methods from a study of an intervention for family members affected by close relatives' substance misuse problems.

Participants: 168 primary healthcare professionals (PHCPs: GPs, practice nurses and health visitors) working in general practices in two areas of England, and who took part in the study.

Data sources: Recruitment and post-session forms completed by PHCPs; telephone interviews with each PHCP 12 weeks after recruitment of a family member; interviews with PHCPs at the end of the study.

Results: At the end of the project PHCPs were overwhelmingly positive about the family member intervention and about primary care as the appropriate site. Difficulties were encountered, however, in identifying and engaging affected family members, who were often excluded on grounds of the complexity of their problems or the level of their distress. Shortage of PHCP time and other practice-related factors added to the difficulty. Active work by a PHCP was often necessary in order to make the link between presenting symptoms of physical or mental ill-health and the existence of a family substance misuse problem. When family members were identified and recruited, PHCPs were usually positive about what was achieved. Nearly all were in favour of an approach that combined giving a self-help manual with some follow-up contact with a family member as needed.

Conclusions: Taken in conjunction with statistical outcome findings of significant reductions in symptoms and changes in ways of coping, plus qualitative analysis of the views of family members, the present results encourage the view that a flexible form of this intervention should be developed for use in primary healthcare, and that further work should build on existing strengths and attempt to overcome weaknesses identified.

Systematic screening for diabetic retinopathy with a digital fundus camera following pupillary dilatation in a university diabetes department.

AIMS: Screening for diabetic retinopathy (DR) is highly inadequate in France because of insufficient infrastructure and increasing disease prevalence. We describe the results of the first systematic DR screening programme established in a university diabetes department. METHODS: In this cross-sectional study conducted over 1 year, consecutive adult patients underwent three-field retinal photography with the Topcon TRC NW6S digital fundus camera following pupillary dilatation with Tropicamide 1%. A questionnaire provided information on patients' systemic and ocular history. Glycated haemoglobin (HbA1c) was measured at the screening visit.Two ophthalmologists graded the retinal photographs in a masked fashion. RESULTS: Of 1157 patients attending the diabetes department, 1153 (99.7%)underwent photographic screening. Images were gradable in 96% patients.Diabetic retinopathy was detected in 522 (45%) patients and sight-threatening DR in 167 (14%). Of 704 (61%) patients previously believed to have no DR,254 (34%) screened positive. The presence of DR was associated with age,insulin use and non-Caucasian ethnicity in Type 2 patients, and with duration of diabetes and HbA1c in Type 1 and Type 2 patients. Associated ocular pathologies were diagnosed in 612 (53%) patients. CONCLUSIONS: Our photographic screening programme using pharmacological mydriasis provided a high screening coverage feasible in a hospital setting. We obtained information regarding prevalence and associated risk factors of DR inpatients attending a tertiary care centre. Screening was well accepted by patients and met with no protest from city ophthalmologists. It generated considerable interest among endocrinologists and feedback of results is expected to improve optimization of glycaemic control.

中国已婚育龄妇女分娩保健服务的状况与变化研究

目的:分析我国已婚育龄妇女分娩保健服务状况及其变化。方法:对全国31个省(直辖市、自治区)抽取的调查前三年有生育史的1962名已婚育龄妇女进行问卷调查,结合1997年全国人口与生殖健康调查资料,对两次调查前三年有生育史妇女最近一次活产的分娩保健服务状况进行比较分析。结果:①与1997年调查前三年相比,2001年调查前三年育龄妇女的入院分娩率增加,家庭分娩的比例明显减少;②农村妇女家庭分娩比例明显降低,由1997年调查时的61·41%降为2001年调查时的40·78%,1998~2000年间,92·54%城镇妇女接受分娩保健服务,农村妇女家庭分娩比例高出城镇7·4倍,为40·78%;③分娩保健服务在各地区发展不平衡,东部和中部地区发展快,西部地区,尤其是西南地区发展相对较慢,1998~2000年间,西部地区妇女中,一半以上在家分娩,西部地区农村家庭分娩妇女一半以上由家人接生,约为东部和中部地区的6倍;④少数民族妇女家庭分娩和由家人接生的比例明显高于汉族妇女;⑤随着文化程度和经济收入的增加育龄妇女对分娩保健服务的利用增加,文盲、经济收入低的妇女家庭分娩比例和由家人接生的比例非常高。结论:我国分娩保健服务状况在改善,但发展极不平衡,西部地区农村的分娩保健服务急待提高。应加强对西部地区分娩保健服务的支持力度,研究制定应对策略,加强对西部农村接生人员的专业技术培训。     

A self-reported survey of Alzheimer's centers in Southwestern Pennsylvania

Directors of nursing at 23 nursing homes with Alzheimer's units in Southwestern Pennsylvania completed a self‐reported survey of 12 questions. Responses from the self‐administered questionnaires (100% response rate) revealed a wide variation in the staff categories assessing the oral health status of newly admitted residents with AD. The respondents described oral examinations that were incomplete when compared to the oral indicators listed in the Minimum Data Set. All nursing homes reported that oral hygiene was provided each day. The number of residents in a facility had a significant effect on the frequency of oral hygiene provided. Only 52% of the facilities reported yearly oral examinations for this population. According to the respondents, dental treatment was typically performed on‐site. The oral health care costs were paid by Medicare, Medicaid, the residents/family members, or by other undescribed resources. Insufficient time, staff, and training, as well as uncooperative behavior, were identified as barriers to optimum oral health care for residents with AD. Additional staff, specialized training, and increased government reimbursement were suggested to improve the oral health care for this group of older adults. For future studies, review of medical records and on‐site evaluation of the oral health care at these facilities should be required to verify the reported practices.     

Monitoring pressure ulcer healing in persons with disabilities.

Pressure ulcers are a high-risk, high-volume, and high-cost problem for persons with disabilities. This article describes four tools published in the literature and reports the validity, reliability, strengths, and limitations of each. These tools include the Pressure Ulcer Scale for Healing (PUSH), the Pressure Sore Status Tool (PSST), the Sussman Wound Healing Tool (SWHT), and the Sessing Scale. Rehabilitation nurses should use a consistent framework with accurate quantification to assess, document, and monitor changes in pressure ulcers over time. Such a measurement tool must prove valid for the disabled population in which the tool is used. This will enable healthcare providers to communicate more effectively and evaluate the therapeutic plan of care.
