Abstract

Point-of-care tests are biomedical tests on patients’ specimens like blood, saliva, urine or faeces, which can be used near the patient, without interference of a laboratory. The use of these tests, many of which have been recently developed, is increasing in general practice, where they add to the GP's set of diagnostic instruments. The question is, however, whether they always contribute to an effective and high-quality diagnostic process by GPs. We present a set of criteria that can be used by guideline developers, regional primary care organizations and individual GPs to evaluate a new point-of-care test in a practice setting. These criteria do not relate only to their use and quality. A point-of-care test needs to be evaluated in the right population and for the right indications, and GPs then need to use them for the indications for which they were evaluated. Expanding the range of indications can lead to an increase in false-positive and false-negative test results.  相似文献

Aims and objectives. To test the transportability and implementation of the Tobacco Tactics intervention using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework, for inpatient units at the Jesse Brown Veterans Affairs Medical Center. Background. Smoking rates are high among veterans. While the Department of Veterans Affairs has standardised outpatient cessation clinics, inpatient cessation services, known to be efficacious, are only sporadically provided. Design. This was a phase 4, pre and postimplementation study of the Tobacco Tactics intervention. Methods. A unique convenience sample of inpatient veteran smokers was recruited both before (n = 54) and after (n = 50) implementation of the Tobacco Tactics programme. Participants completed baseline and 30‐day follow‐up surveys along with urine cotinine test kits. In addition, staff completed anonymous surveys during the preintervention period (n = 158) and two months after (n = 81) the Tobacco Tactics training. Bivariate analyses compared preintervention vs. postintervention patient and staff characteristics using Chi‐square, Fisher’s Exact or Student’s t‐test. p‐values <0·05 were considered significant. Results. Patient‐reported receipt of services and satisfaction was 10% higher in the postintervention compared to the preintervention group. Quit rates were 3% higher in the postintervention than in the preintervention group. The mean number of cigarettes smoked per day increased from 13 to 15 in the preintervention group, while the mean number of cigarettes smoked per day decreased from 14 to 9 in the postintervention group. Staff’s confidence in their ability to provide cessation services improved greatly posttraining (p = 0·0017) as did self‐reported delivery of cessation services (p = 0·0154). Conclusions. With as little as one‐hour training for nurses, the Tobacco Tactics intervention has the potential to be widely disseminated in the Department of Veterans Affairs. Relevance to clinical practice. The implementation of inpatient smoking interventions has the potential to improve quit rates and decrease morbidity and mortality in the Department of Veterans Affairs.  相似文献

Aims and objectives. To examine the activities and resource implications for the initial cohort of healthcare organisations involved in the introduction of multiple nursing guidelines. Background. The Best Practice Spotlight Organization initiative was launched in 2003 as part of the Registered Nurses’ Association of Ontario’s Best Practice Guidelines programme. While previous research has evaluated improvements in patient care and outcomes, there has been limited research from an organisational perspective on the activities conducted to introduce nursing guidelines. Design. Secondary analysis of retrospective narrative data. Methods. We conducted a content analysis of the 2004–2006 annual reports from the seven participating sites. We used both deductive and inductive approaches to categorise the guideline implementation activities and their resource implications. Results. All sites reported implementing multiple guidelines (four to nine guidelines per site) and used a wide range of implementation activities that clearly addressed nine of the 10 NHS Sustainability dimensions. The dimension not reported was benefits beyond helping patients. All sites established steering committees that involved staff and senior leaders, reviewed selected guidelines and recommendations, reviewed existing policies and procedures and developed new policies and procedures, recruited champions or peer mentors, applied for additional external funding to support activities, developed relationships with external clinical partners, included guideline implementation in orientation, developed intra‐agency web‐based and print communications for the project, and evaluated practice changes. For each of these activities, the sites reported expenditures and resource usage. Conclusions. The organisational processes used for the introduction of new nursing guidelines in Canada are remarkably consistent with factors identified by leaders and change agents in the UK who developed the NHS Sustainability Model. Relevance to clinical practice. A multidimensional framework for sustainability is useful for planning successful guideline implementation across an organisation. Examples of specific activities and resource implications for organisational change are provided.  相似文献
