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     

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.

单侧入路椎体后凸成形术治疗老年骨质疏松性胸腰椎压缩性骨折临床研究

目的：探讨单侧入路椎体后凸成形术治疗老年骨质疏松性胸腰椎压缩性骨折的临床疗效和安全性。方法：将15例老年骨质疏松性胸腰椎压缩性骨折患者，行单侧入路穿刺椎体后凸成形术。记录手术时间和透视次数，观察术后患者背痛缓解程度及日常活动恢复情况，比较术前、术后伤椎高度和脊柱后凸畸形Cobb’S角。结果：15例患者均顺利完成手术，手术时间25～43min，平均28．6min；透视次数15～23次，平均19．8次；术后伤椎前部、中部高度，脊柱后凸畸形Cobb’S角与术前比较，差异有统计学意义（P〈0．05）；术后24h患者背痛均明显缓解，与术前比较差异有统计学意义（P〈0．05）。患者均能在术后次日下床行走，未发现神经损伤等手术并发症。结论：单侧入路穿刺球囊扩张椎体后凸成形术能有效地治疗老年骨质疏松性胸腰椎压缩性骨折，且操作简便、安全，能明显地减少患者和术者的放射暴露。

Development of the student placement evaluation form: A tool for assessing student fieldwork performance

Evaluation of students undertaking fieldwork education placements is a critical process in the health professions. As training programs and practice evolve, systems for assessing students need to be reviewed and updated constantly. In 1995, staff of the occupational therapy training program at the University of Queensland, Australia decided to develop a new tool for assessing student fieldwork performance. Using an action research methodology, a team developed the Student Placement Evaluation Form, a flexible and comprehensive criterion-referenced evaluation tool. The present paper examines action research as an appropriate methodology for considering real-life organisational problems in a systematic and participatory manner. The action research cycles undertaken, including preliminary information gathering, tool development, trial stages and current use of the tool, are detailed in the report. Current and future development of the tool is also described.
