European clinical practice guidelines for depression in adults: Are they good enough?

Development and validation of a prediction score to assess the risk of depression in primary care

BACKGROUND

Major depression is the most frequent psychiatric disorder and primary care is a crucial setting for its early recognition. This study aimed to develop and validate the DEP-HScore as a tool to predict depression risk in primary care and increase awareness and investigation of this condition among General Practitioners (GPs).

METHODS

The DEP-HScore was developed using data from the Italian Health Search Database (HSD). A cohort of 903,748 patients aged 18 years or older was selected and followed until the occurrence of depression, death or end of data availability (December 2019). Demographics, somatic signs/symptoms and psychiatric/medical comorbidities were entered in a multivariate Cox regression to predict the occurrence of depression. The coefficients formed the DEP-HScore for individual patients. Explained variance (pseudo-R2), discrimination (AUC) and calibration (slope estimating predicted-observed risk relationship) assessed the prediction accuracy.

RESULTS

The DEP-HScore explained 18.1 % of the variation in occurrence of depression and the discrimination value was equal to 67 %. With an event horizon of three months, the slope and intercept were not significantly different from the ideal calibration.

LIMITATIONS

The DEP-HScore has not been tested in other settings. Furthermore, the model was characterized by limited calibration performance when the risk of depression was estimated at the 1-year follow-up.

CONCLUSIONS

The DEP-HScore is reliable tool that could be implemented in primary care settings to evaluate the risk of depression, thus enabling prompt and suitable investigations to verify the presence of this condition.

The quality of four psychology practice guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE) II

RATIONALE, AIMS AND OBJECTIVES

Clinical Practice Guidelines (CPGs) have been shown to improve healthcare services and clinical outcomes. However, they are useful resources only to the degree that they are developed according to the most rigorous standards. Multiple studies have demonstrated significant variability between CPGs with regard to specific indicators of quality. The Ordre des psychologues du Québec (OPQ), the College of psychologists of Quebec, has published several CPGs that are intended to provide empirically supported guidance for psychologists in the areas of assessment, diagnosis, general functioning, treatment and other decision-making support. The aim of this study was to evaluate the quality of these CPGs.

METHODS

The Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument was used to assess the quality of the CPGs.

RESULTS

Our results show that although there have been some modest improvements in quality of the CPGs over time, there are important methodological inadequacies in all CPGs evaluated.

CONCLUSIONS

The findings of this study demonstrate the need for more methodological rigour in CPGs development as such, recommendations to improve CPG quality are discussed.

The Quality of Six Clinical Practice Guidelines in Health and Social Sciences: Are We on the Right Track?

Interest in the development and promotion of clinical practice guidelines (CPGs) continues to grow in many professions. However, the potential benefits associated with CPGs are dependent upon their quality. A number of studies have shown that the quality of CPGs varies greatly. Furthermore, the quality of many of the CPGs used in health and social sciences has yet to be examined. In light of this, the aim of this study was to examine the quality of CPGs that focus on intervention and care management in mental health in Quebec. A search of Quebec regulatory bodies websites was conducted and six CPGs were included in this study. The CPGs were assessed by four trained raters using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. Items scores and domains scores were considered to determine the quality of the six CPGs. Results show that many of the CPGs did not achieve minimum ratings for numerous quality checks. Notably, none of the CPGs were designed using a rigorous methodology, they lacked transparency throughout the development process and insufficient consideration was given to the applicability of the recommendations they included. Because these shortcomings may hinder the efficacy and utilization of CPGs, suggestions to improve the development of CPGs and to improve their quality are discussed.

An appraisal of published clinical guidelines in anesthesiology practice using the AGREE II instrument

PURPOSE

Clinical practice guidelines are developed to provide physicians with appraised scientific evidence and enhance their medical decision-making process. Poorly developed guidelines can have a negative impact on patient care, but the quality of clinical guidelines has not been evaluated in anesthesiology practice.

METHODS

We evaluated the quality of clinical practice guidelines in anesthesiology retrieved from PubMed, Scopus, Cochrane Library, and Embase databases from August 2013 to August 2018 using a validated appraisal instrument. Exclusion criteria excluded consensus statements, editorials, non-clinical/legal-themed manuscripts, institutional protocols, research methods, and chronic pain and surgical technique guidelines.

PRINCIPAL FINDINGS

A total of 96 clinical practice guidelines were included in the analysis. Seventy-one out of 96 (74%; 95% confidence interval, 65 to 83) guidelines had overall quality scores lower or equal to 5 and could not be recommended as published. Higher quality guidelines (overall score greater than 5) were published in journals with higher median [interquartile range] impact factors than lower quality guidelines (4.0 [3.5-6.5] vs 3.8 [2.3-4.7]; P = 0.02). The publication of a higher quality guideline was not associated with the year that the guideline was published or if the guideline was published by a society.

CONCLUSIONS

The overall quality of most guidelines relevant to the practice of anesthesiology were poor, and the domains applicability and rigor of development rated particularly low. Future groups developing clinical guidelines should consider using methodological support to improve the quality of guidelines relevant to the practice of anesthesiology.

Relapse prevention in recurrent major depressive disorder. A comparison of different treatment options based on clinical experience and a critical review of the literature

BACKGROUND

Reducing the risk of relapses is a critical component of major depressive disorders treatment. Guidelines suggest maintenance with antidepressant drugs in recurrent depression, but this solution has recently been questioned.

OBJECTIVE

The aim of this article is to provide a critical review of the literature of the main treatment options currently available to prevent relapse and recurrence in depression.

METHODS

We compared long-term antidepressant therapy (i.e., indefinite maintenance of antidepressant), intermittent antidepressant therapy (i.e., use of antidepressants mainly limited to the acute phases), use of psychotherapy in the sequential model (i.e., pharmacotherapy in the acute phase and psychotherapy in the residual phase).

RESULTS

We argue that the same solution may not apply to all patients and question the feasibility of a single course of treatment in the setting of complex disorders that are encountered in practice. The clinician should weigh advantages and disadvantages in the individual case.

CONCLUSIONS

The sequential model appears to be particularly indicated in recurrent depression. KEY POINTS Relapse is a major challenge of depressive disorders treatment Treatment options currently available include long-term antidepressants, intermittent antidepressants, addition of psychotherapy to pharmacotherapy in the sequential model Maintenance with antidepressants in recurrent depression has recently been questioned The sequential model appears to be particularly indicated in recurrent depression.
