Practice guidelines: a more rational approach to diagnosis and treatment and a more effective use of health care resources

Availability and perceived usefulness of guidelines and protocols for subcutaneous hydration in palliative care settings

AIMS AND OBJECTIVES

To evaluate the availability of, adherence to, and perceived usefulness of guidelines and protocols for managing hydration and subcutaneous hydration in palliative care settings.

BACKGROUND

Hydration at the end of life and the use of a subcutaneous route to hydrate generate some controversy among health professionals for different reasons. Having guidelines and protocols to assist in decision-making and to follow a standard procedure may be relevant in clinical practice.

DESIGN

Cross-sectional telephone survey, with closed-ended and open-ended questions designed specifically for this study.

METHODS

Data were obtained from 327 professionals, each from a different palliative care service. Mean, standard deviation, minimum and maximum were calculated for continuous variables; frequency distributions were obtained for categorical variables. A qualitative content analysis was performed on the open-ended questions. The article adheres to the STROBE guidelines for reporting observational studies.

RESULTS

Only 24.8% of the participants had guidelines available to assist in making decisions regarding hydration, and 55.6% claimed to follow them 'always or almost always'. Of the participants, 38.8% had subcutaneous hydration protocols available, while 78.7% stated that they 'always or almost always' followed these protocols. The remaining participants considered the protocols as useful tools despite not having them available.

CONCLUSIONS

Only 25% of the participants' services had guidelines for hydration, and less than 40% had protocols for subcutaneous hydration. However, adherence was high, especially in cases where protocols existed. Among the participants who did not have guidelines and protocols, attitudes were mostly favourable, but mainly as a reference and support for an individualised clinical practice.

RELEVANCE TO CLINICAL PRACTICE

Guidelines and protocols on hydration in palliative care may be more useful as a solid reference and support for individualised practice than as instruments for standardising care. From this perspective, their development and availability in palliative care services are recommended.

Colorectal cancer guidelines seldom include the patient perspective

OBJECTIVES

This study aimed to describe how colorectal practice guidelines (PGs) incorporate the patient perspective.

STUDY DESIGN AND SETTING

We searched in the Guidelines International Network library, MEDLINE, National Guideline Clearinghouse, NHS Evidence database, and TRIP database. Two authors independently selected the PGs. We considered recommendations rated or worded as weak or conditional or suggesting multiple options, as potentially preference sensitive. Two authors independently evaluated if, in potentially sensitive recommendations, the patient perspective was incorporated.

RESULTS

We included 28 PGs that contained 588 recommendations, being 256 potentially preference sensitive. Ten PGs (36%) included patients in the development process, and 12 (43%) provided information about patients' perspectives. Nine PGs (32%) included recommendations in which the patient perspective was explicitly considered, and 13 (46.4%) that recommended a discussion with the patient. From a total of 588 recommendations, 9.7% (25/256) of potentially preference-sensitive recommendations considered the patient perspective. The inclusion of patients in the development process was associated with a more frequent incorporation of the patient perspective in potentially preference sensitive recommendations (70% vs. 0%; P < 0.001).

CONCLUSIONS

Guideline users should be aware that the incorporation of the patient perspective in colorectal cancer PGs is suboptimal. Guideline developers should make efforts to incorporate the patient perspective, especially in preference-sensitive recommendations.

Clinical guidelines for prevention and management of preterm birth: a systematic review

BACKGROUND

Clinical practice guidelines (CPG) endorse multiple strategies to prevent or manage preterm birth (PTB).

OBJECTIVES

To summarise CPG recommendations for PTB and identify areas of international consensus.

SEARCH STRATEGY

In May 2017 we searched for all CPG relevant to PTB without language restrictions.

SELECTION CRITERIA

CPG were eligible if the following criteria were met: (1) the guideline was published or current from June 2013; (2) the guideline recommended practices for the prevention or management of PTB relevant to our prespecified clinical questions for screening, medications or surgery and other interventions; (3) publications on methods of guideline development for eligible CPG were included to enable quality assessment.

DATA COLLECTION AND ANALYSIS

Two authors classified CPG recommendations relevant to prespecified clinical questions. When more than 70% of CPGs reporting on a topic recommended or rejected an intervention, we regarded this as consensus. We summarised recommendations in tables.

MAIN RESULTS

We identified 49 guidelines from 16 guideline developers. We found consensus for several clinical practices: cervical length screening for high-risk women; short-term tocolysis; steroids for fetal lung maturation; and magnesium sulphate for fetal neuroprotection. We found discrepant recommendations for progesterone and fibronectin. No guideline identified an effective strategy for women with multiple pregnancy.

CONCLUSIONS

We identified interventions for which there is an international consensus on benefit for PTB. Systematic reviews of CPG using standardised methodology will help avoid duplication and target scarce resources for guideline developers globally.

TWEETABLE ABSTRACT

International clinical guidelines agree on the benefits and harmful effects of several important interventions to prevent preterm birth.

Incorporating patients' views in guideline development: a systematic review of guidance documents

OBJECTIVES

To assess how guidance documents for developing clinical guidelines (CGs) address the incorporation of patients' views in CGs.

STUDY DESIGN AND SETTING

Systematic review to identify the methodology provided in guidance documents for incorporating (1) patients or representatives and (2) patients' views in the CG development process. The search was performed in 2017 in five databases. Two authors selected the studies, and data extraction was double-checked.

RESULTS

We included guidance documents from 56 institutions. Of those, 40 (71.4%) recommended the inclusion of patients or their representatives, mainly for developing recommendations (14/40, 35.0%); reviewing the final version (13/40, 32.5%); formulating clinical questions (13/40, 32.5%); defining the scope and objectives (10/40, 25.0%); and dissemination and implementation (10/40, 25.0%). Concrete methods on how to incorporate patients were provided by 47.5% (19/40) of institutions. Forty (71.4%) institutions provided additional strategies to incorporate patients' views. The majority (30/40, 75.0%) suggested sources for obtaining these views (consultation with patients [24/40, 60.0%], using panels' judgment [10/40, 25.0%], conducting de novo research [10/40, 25.0%], or a systematic review [9/40, 22.5%]).

CONCLUSION

Although most institutions suggest incorporating patients and their views when developing CGs, little detail is provided on how to do this. Institutions should provide more guidance as this could have a positive impact in guideline applicability.

Priority-based initiative for updating existing evidence-based clinical practice guidelines: the results of two iterations

OBJECTIVES

New evidence continues to emerge and requires attention after the release of a clinical practice guideline (CPG). The objective of this article is to describe the Document Assessment and Review (DAR) strategy designed to ensue that the CPGs remain current and their quality maintained and to present the results of two iteration of its implementation.

STUDY DESIGN AND SETTING

The DAR process involves an annual assessment of our CPGs and a review of documents that require an update search. Two questionnaires are used to conduct the annual assessment and the review. The review involves evidence search, evidence review, and review approval.

RESULTS

In 2011, 109 documents were assessed; 22 (20%) were archived, 1 (1%) was deferred for assessment in 2012, 24 (22%) were considered special cases and 62 (57%) needed a new systematic review of the evidence. Of those 62, 19 (31%) were categorized as urgent, 16 (26%) as high, and others as medium or low priority. In 2012, 88 total documents were assessed; 15 (17%) were archived, 32 (36%) deferred, 3 (3%) were considered special cases, and 38 (43%) were prioritized for review.

CONCLUSIONS

Assessment and prioritization of existing CPGs are effective ways of ensuring that resources are directed toward the upkeep of those that are relevant and of highest priority.

Increased neuroinflammatory and arachidonic acid cascade markers, and reduced synaptic proteins, in brain of HIV-1 transgenic rats

Background

Cognitive impairment has been reported in human immune deficiency virus-1- (HIV-1-) infected patients as well as in HIV-1 transgenic (Tg) rats. This impairment has been linked to neuroinflammation, disturbed brain arachidonic acid (AA) metabolism, and synapto-dendritic injury. We recently reported upregulated brain AA metabolism in 7- to 9-month-old HIV-1 Tg rats. We hypothesized that these HIV-1 Tg rats also would show upregulated brain inflammatory and AA cascade markers and a deficit of synaptic proteins.

Methods

We measured protein and mRNA levels of markers of neuroinflammation and the AA cascade, as well as pro-apoptotic factors and synaptic proteins, in brains from 7- to 9-month-old HIV-1 Tg and control rats.

Results

Compared with control brain, HIV-1 Tg rat brain showed immunoreactivity to glycoprotein 120 and tat HIV-1 viral proteins, and significantly higher protein and mRNA levels of (1) the inflammatory cytokines interleukin-1β and tumor necrosis factor α, (2) the activated microglial/macrophage marker CD11b, (3) AA cascade enzymes: AA-selective Ca²⁺-dependent cytosolic phospholipase A₂ (cPLA₂)-IVA, secretory sPLA₂-IIA, cyclooxygenase (COX)-2, membrane prostaglandin E₂ synthase, 5-lipoxygenase (LOX) and 15-LOX, cytochrome p450 epoxygenase, and (4) transcription factor NF-κBp50 DNA binding activity. HIV-1 Tg rat brain also exhibited signs of cell injury, including significantly decreased levels of brain-derived neurotrophic factor (BDNF) and drebrin, a marker of post-synaptic excitatory dendritic spines. Expression of Ca²⁺-independent iPLA₂-VIA and COX-1 was unchanged.

Conclusions

HIV-1 Tg rats show elevated brain markers of neuroinflammation and AA metabolism, with a deficit in several synaptic proteins. These changes are associated with viral proteins and may contribute to cognitive impairment. The HIV-1 Tg rat may be a useful model for understanding progression and treatment of cognitive impairment in HIV-1 patients.

Clinical practice guidelines to improve shared decision-making about assistive device use in home care: a pilot intervention study

This study examines whether clinical practice guidelines (CPG) for the introduction of assistive devices (ADs) in home care improve shared decision-making about AD use and modify its social-cognitive correlates. Data were collected in an intervention study with quasi-experimental design. Questionnaires were obtained from 116 home nurses and home care workers and their 140 clients with disabilities. Significant differences between intervention and control group revealed that implementation of CPG improved home nurses' and home care workers' self-reported practice: the number of intervention methods they applied increased, and the methods were applied with increased intensity. Nurses' attitudes towards introducing ADs in a shared decision-making process decreased in both intervention group and control group over time. Clients' reports about caregivers' practice showed a minor concurrence with the reports of the caregivers themselves. The complexity of the CPG and a substantial time investment were reported as the main barriers to involving clients in shared decision-making through the experimental CPG. Nevertheless, CPG hold promise for shared decision-making between formal caregivers and community-dwelling persons with disabilities concerning AD use. The findings suggest that these CPG can structure communication between caregiver and client, and can support caregivers in facilitating clients' self-determination concerning coping with their disabilities.

Current trends in antiepileptic drug therapy

Over the last two decades, drug therapy for epilepsy has improved substantially. This can be ascribed to a large extent to three factors, including the demonstration of the advantages of monotherapy; the realization of the need for dosage tailoring, coupled [for some antiepileptic drugs (AEDs)] with control of pharmacokinetic variability through therapeutic drug monitoring; and the introduction of newer agents with improved tolerability profiles. What further advances should we expect for the future? Current trends that are expected to increasingly affect our prescribing patterns include greater reliance on evidence-based medicine and treatment guidelines, a trend that will be facilitated by completion of therapeutically meaningful randomized trials (including cost-effectiveness studies) and high-quality observational studies (including multinational pregnancy registries), as well as initiatives from scientific societies and government organizations aimed at condensing the most relevant information into therapeutic guidelines. The explosion in communication technology will accelerate dissemination of this information and its application to clinical practice. Other factors include a more rational patient-tailored AED selection and dose individualization, aided by characterization of predictors of outcome as defined by clinical parameters (sex, age, epilepsy syndrome, and etiology), pathophysiological mechanisms, and newly discovered genetic markers of outcome; improved definition of the role of new AEDs, resulting in their increased use in newly diagnosed epilepsy; and reappraisal of the value of combination therapy in refractory epilepsies, based on evidence produced by experimental and clinical studies designed to identify favorable pharmacodynamic interactions. Additional important developments may come from the discovery of novel, more efficacious AEDs and from exploration of potential new targets, such as prevention of epileptogenesis.

Appropriateness in programs for continuous quality improvement in clinical laboratories

BACKGROUND

External reviews and the accreditation of medical laboratories involve more than the mere assessment of conformance with standards for organisational processes. The new approaches to quality improvement suggest that, rather than using inspection to correct unusual errors, there should be more emphasis on improving the processes of health care to ensure that desired outcomes are produced. Appropriateness plays a key role in programs for quality improvement.

METHODS

Appropriateness in laboratory medicine can be assessed, and improved, through the governance of the entire testing process. This begins with test selection, proceeds through valuable pre-, intra- and post-analytical procedures, and concludes by assuring the correct interpretation and utilization of laboratory information.

RESULTS

The International Standard, specifically developed for medical laboratories (ISO 15189) recognizes the value of appropriate interpretation and advisory services, although it does not specify requirements for assessing appropriateness, requesting tests and interpreting results. The effectiveness of clinical laboratories can be assessed by using surrogate markers, which indicate physicians' satisfaction, and clinical audits. Effectiveness is also enhanced by stressing the importance of the technical and professional competence of evaluators.

CONCLUSIONS

Inappropriate laboratory utilization unjustifiably increases health care costs, can harm patients and perpetuates the vision of laboratory testing as a commodity. Improvement in laboratory appropriateness can be achieved by seeking a better relationship with physicians and by stressing the role of laboratory specialists in providing clinical advice for the selection of laboratory tests, and the interpretation and utilization of their results, thus leading to more satisfactory clinical outcomes.

Guidelines and Algorithms: Perceptions of Why and When They Are Successful and How to Improve Them

Medicine is increasingly complex, a reality created by the explosion of knowledge during the last 50 years. The cost of applying this knowledge creates a daunting economic challenge. As a result, there has been a profusion of guidelines intended to influence medical practice. This report explores the interrelated issues and concepts that impact the value and success of guidelines. These include medical quality and error, compliance, and the impact on outcomes in an evidence-based medicine context. Lessons learned from previous guidelines must be understood in relation to human behavior. Legal implications of the guidelines must be considered because both an increase and a decrease in liability can be anticipated. Many products have been labeled “advocacy guidelines” with a negative context. They are believed to express motivation rather than optimizing care. The ideal of professionalism is challenged, and there is potential for the growing use of guidelines in enforcing punitive actions. Constructive experience has emphasized the appropriate required elements for practice guidelines: a systematic review of the literature, an assessment of the volume and level of the evidence, and development of a review process by an appropriate multidisciplinary group for consistency, clinical impact, and resource implications leading to clearly stated and reasonable recommendations. The dissemination of guidelines, beyond conventional publication in a journal, will impact the success of the intended outcomes. The exploitation of electronic avenues, including the Internet and the evolving interactive electronic medical record, seems to be essential for future success in these endeavors.
