Implementing practice guidelines for depression: applying a new framework to an old problem

Integrating palliative and critical care: description of an intervention

A large proportion of deaths in the United States occur in the intensive care unit (ICU) or after a stay in the ICU, and there is evidence of problems in the quality of care these patients and their families receive. In an effort to respond to this problem, we developed a multifaceted, nurse-focused, quality improvement intervention that is based on self-efficacy theory applied to changing clinician behavior. We have called the intervention "Integrating Palliative and Critical Care." This five-component intervention includes: 1) critical care clinician education to increase knowledge and awareness of the principles and practice of palliative care in the ICU, 2) critical care clinician local champions to provide role modeling and promote attitudinal change concerning end-of-life care, 3) academic detailing of nurse and physician ICU directors to identify and address local barriers to improving end-of-life care in each ICU, 4) feedback of local quality improvement data, and 5) system supports including implementation of palliative care order forms, family information pamphlets, and other system supports for providing palliative care in the ICU. The goal of this report is to describe the conceptual model that led to the development of the intervention, and for each of the five components, we describe the theoretical and empirical support for each component, the content of the component, and the lessons we have learned in implementing the component. Future reports will need to examine the ability of the interventions to improve outcomes of palliative care in the ICU.

Improving depression care for ethnic and racial minorities: a concept for an intervention that integrates CME planning with improvement strategies

Depression is one of the most common reasons that individuals seek treatment in the primary care setting. Research in the past 15 years has shown that dramatic improvement in the management of patients with depression is possible. Advances in pharmacotherapy and delivery of depression care have been reported, but few currently benefit members of ethnic and racial minorities. Educating physicians and other health professionals has been suggested as one approach to address the issues related to disparities in depression care. There is little evidence, however, that education alone is effective. The authors of this article believe that incorporating physician learning activities that are planned using approaches that have been shown to be effective in interventions currently demonstrating some success in improving depression care provided to ethnic and racial minorities will enhance the impact and sustainability of these interventions. This article--the conclusion of this supplement--will describe an intervention concept that integrates a quality improvement model (the Institute for Health Improvement's Breakthrough Series Collaborative model) with an evidence-based approach to planning CME and supports the integration by using action inquiry technologies and community-based participatory research methods. Relevant approaches from implementation research are discussed, and suggestions for testing the intervention concept are provided.

Costs and consequences of enhanced primary care for depression: systematic review of randomised economic evaluations

BACKGROUND

A number of enhancement strategies have been proposed to improve the quality and outcome of care for depression in primary care settings. Decision-makers are likely to need to know whether these interventions are cost-effective in routine primary care settings.

METHOD

We conducted a systematic review of all full economic evaluations (cost-effectiveness and cost-utility analyses) accompanying randomised controlled trials of enhanced primary care for depression. Costs were standardised to UK pounds/US dollars and incremental cost-effectiveness ratios (ICERs) were visually summarised using a permutation matrix.

RESULTS

We identified 11 full economic evaluations (4757 patients). A near-uniform finding was that the interventions based upon collaborative care/case management resulted in improved outcomes but were also associated with greater costs. When considering primary care depression treatment costs alone, ICER estimates ranged from 7 ($13, no confidence interval given) to 13 UK pounds ($24,95% CI -105 to 148) per additional depression-free day. Educational interventions alone were associated with increased cost and no clinical benefit.

CONCLUSIONS

Improved outcomes through depression management programmes using a collaborative care/case management approach can be expected, but are associated with increased cost and will require investment.

Implementation of guideline-based care for depression in primary care

Evidence-based clinical practice guidelines for treating depression in primary care settings were developed, in part, to ensure that health services are provided in a consistent, high-quality, and cost-effective manner. Yet for a variety of reasons, guideline-based primary care for depression remains the exception rather than the rule. This work provides a brief review of effective strategies used to customize and then deliver evidence-based treatment for depression in primary care settings; describes two representative case studies that illustrate locally customized collaborative care strategies for treatment delivery; and concludes with principles and implications for policy and practice based on our practical experiences.

Algorithms and collaborative-care systems for depression: are they effective and why? A systematic review

BACKGROUND

Treatment algorithms and collaborative-care systems are systematic treatment approaches that are designed to improve outcomes by enhancing the quality of care. During the last decade, algorithm research has evolved as a new branch of clinical research that evaluates the clinical and economic impact of algorithm-guided treatment in primary and psychiatric care of patients with depressive disorders.

METHODS

This article discusses the rationale of algorithm development, their risks and limitations, and important elements in their implementation in clinical practice. It further reviews the available studies that have evaluated algorithm-guided treatment for depression.

RESULTS

Recent studies show that compared with treatment as usual, the use of algorithms and collaborative-care approaches in the care of depressed patients enhances treatment outcomes by modifying practice procedures and treatment processes.

CONCLUSIONS

Treatment algorithms and collaborative-care systems clearly increase the efficacy of applied treatments in the care of depressed patients. However, to what extent the enhanced outcomes are a result of diligent measurement-based care or of the specific treatment steps that are used remains to be resolved. Valid clinical or pharmacogenetic predictors of response are needed to further tailor specific algorithms to individual patients.

Translation in the health professions: converting science into action

The systematic translation of evidence-based research findings, tools, and information into practice is critical to improving the quality of our nation's health. However, despite several decades of advances in developing medical knowledge based on high-quality empirical evidence, widespread implementation of these findings into practice in diverse applied settings has not been achieved. This article reviews definitions and conceptual models that describe the translation of research from basic discovery to real-world applications, summarizes the various issues involved in the process of translation, discusses multiple barriers, and provides recommendations to surmount these hurdles. Areas of further research in this arena are suggested. Finally, the article concludes that translational research is an important area to continue to pursue requiring long-term collaborative commitment among researchers and practitioners.

Facilitated Process Improvement: An Approach to the Seamless Linkage Between Evidence and Practice in CKD

BACKGROUND

Two common strategies for guideline implementation are preformed practice improvement tools, such as flowcharts, and process reengineering by total quality management (TQM) teams. Prespecified tools fail to accommodate local circumstances, TQM requires an unrealistic level of local commitment, and neither has a proven track record for success.

METHODS

We describe an alternative approach termed facilitated process improvement (FPI), a systematic exploration of potential modifications to systems of care, and its application to the implementation of an evidence-based chronic kidney disease (CKD) guideline, focusing on individuals not yet requiring renal replacement therapy. The FPI steps followed by the implementation work group to develop a set of implementation tools for the Renal Physicians Association Advanced CKD Guideline included: (1) developing functional specifications of processes, including actions and prerequisites required; (2) investigating processes of care in a variety of site types to understand processes and reasons for failures; (3) developing practical tools corresponding to root causes of failures of processes and subprocesses; and (4) developing a meta-tool to tailor local selection of tools.

RESULTS

Formal needs assessment identified processes of care related to 3 major tasks: identify patients, develop and communicate patient-specific management plan, and implement plan. Subtasks were identified to address root causes of failures, and, for each, tools were modified from existing or developed de novo by the work group, which further developed an organized management approach that uses 4 categories of tools: (1) assessment tools identify opportunities for improvements; (2) tailoring tools, a unique feature of this approach, determine which tools are applicable; (3) implementation tools identify patients and communicate and implement management plan; and (4) evaluation tools assess the impact of implementation.

CONCLUSION

The work group, in collaboration with community clinicians, patients, and CKD and tool experts, developed and used FPI to provide a range of tools in a fashion that supports and simplifies local assessment, tailoring, implementation, and evaluation. With the formative work completed, practitioners whose practice improvement experience level and other resources may be limited will find it more feasible and practical to provide optimal advanced CKD management without the demands of conventional TQM or continuous quality improvement.

[Local guidelines and quality of antibiotic treatment in urinary tract infections: a clinical audit in two departments of a university hospital]

AIM

To assess the effect of local guidelines implemented at the Nantes University Hospital regarding antibiotic therapy for urinary tract infections.

DESIGN

Before/after study of one medical ward and one urologic surgery ward. Quality was measured by two principal criteria: compliance with guidelines and medical justification in the specific clinical situation. Both criteria considered simultaneously the choice of drug, dose and duration of treatment. Deviations from the guidelines were described.

RESULTS

1086 UTI cases were identified over two 12-month periods, before and after the dissemination of guidelines (for prostatitis, pyelonephritis, indwelling catheter-associated UTIs, and other undefined UTIs). The guidelines were applicable in 313 (30%) cases. Overall, after implementation of the guidelines, the percentage of justified prescriptions did not change significantly (41.8% compared with 38.7%, p=0.299), but the percentage of correct (conforming) prescriptions fell (from 30.4% to 15.7%, p=0.0022). The percentages of correct and justified prescriptions differed in the medical (respectively 45.0% and 46.6%,) and surgical units (13.1% and 36.5%).

CONCLUSIONS

Issuing guidelines does not necessarily improve the quality of antibiotic therapy for UTIs in hospitals.

Pilot of a pathway to improve the care of imminently dying oncology inpatients in a Veterans Affairs Medical Center

We report on the implementation of a previously developed clinical pathway for terminally ill patients, Palliative Care for Advanced Disease (PCAD), on a Veterans Administration (VA) acute care oncology unit, comparing processes of care and outcomes for patients on and off the pathway. The PCAD pathway is designed to identify imminently dying patients, review care goals, respect patients' wishes, assess and manage symptoms, address spirituality, and support family members. Retrospective chart reviews from 15 patients who died on PCAD, 14 patients who died on general wards during the same time, and 10 oncology unit patients who died prior to PCAD revealed that PCAD patients were more likely to have documentation of care goals and plans of comfort care (P=0.0001), fewer interventions, and more symptoms assessed (P=0.004), and more symptoms managed according to PCAD guidelines (P=0.02). Implementation of PCAD improved care of dying inpatients by increasing documentation of goals and plans of care, improving symptom assessment and management, and decreasing interventions at the end of life.

Practitioner perspectives on evidence-based practice

Most aspiring child mental health professionals would support the premise that clinical practice should have a scientific foundation. Why, then, is the implementation of evidence-based practice in child and adolescent psychiatry so difficult? Considering the multiple stakeholders in clinical work, impediments are not surprising. Practitioner delays in implementation of research findings are common to all specialties of medicine. This article outlines the barriers to implementation of evidence-based practice and suggests changes to motivate and enable clinicians to use evidence-based practices.

Bonnes pratiques de prescription des antibiotiques pour la prise en charge des infections urinaires en milieu hospitalier : identification des écarts aux recommandations et actions correctrices

OBJECTIVE

We analyzed the adequacy of antibiotic therapy prescribed for urinary tract infections (UTI): prostatitis, pyelonephritis, indwelling catheter-associated UTIs, or other undefined UTIs.

DESIGN

The adequacy of prescriptions to local guidelines was assessed retrospectively in two wards (Internal Medicine and Surgical Urology) of the Nantes University Hospital. The principal criteria involved simultaneously: choice of the molecule, dose, and treatment duration. Non-observances of guidelines were major (non-adequacy of the molecule, prescription of a non-active molecule according to in vitro susceptibility tests, non-appropriate treatment abstention), or minor (non-justified treatment, non-justified bitherapy, no prescription of bitherapy when requested, no treatment adaptation when requested, too short or too long treatment length, dosage mistakes).

RESULTS

One thousand eighty-six infections were collected over a 24-month period. The overall rate of adequate prescriptions was 40.1% (46.6% in Internal Medicine and 36.5% in Surgical Urology). In Internal Medicine (226 non observance among 389 prescriptions), the ratio of major non-observance of guidelines was 9.8%. Among them, 44.7% were non-appropriate treatment abstentions. In Surgical Urology (539 non observance out of 695 prescriptions), non-observance related to treatment length were the most frequent. The ratio of major non-observance was 19.9%. Among them, non-adequacy of the molecule reached 60.7%. Non-justified treatment and non-appropriate bitherapies were frequent.

CONCLUSIONS

For both units, indwelling catheter-related UTIs and other UTIs accounted for more than 50% of the infections although not detailed in the local guidelines. Identifying and analyzing Non observance may lead to targeted correcting actions to improve prescription quality.

Influence of guideline adherence on outcome in a randomised controlled trial on the efficacy of methotrexate with folate supplementation in rheumatoid arthritis

OBJECTIVE

To study the influence of rheumatologists' adherence to a methotrexate guideline on efficacy and toxicity in the treatment of rheumatoid arthritis.

METHODS

In a 48 week randomised controlled trial of methotrexate, comparing folates with placebo, rheumatologists were advised on methotrexate dosage using a guideline reflecting daily practice. The influence of guideline non-adherence on outcome was analysed using generalised estimating equations and survival analysis.

RESULTS

In 51% of the 411 study patients the guidelines were always followed. Non-adherence resulted in lower doses of methotrexate in 25% of cases, and higher doses in 24%. The reduction in the disease activity score was significantly greater (mean -0.4; p = 0.0085) in the adherent group than in the "low dose" group; the "high dose" group did not differ from the adherent group. Dropout caused by severe adverse events did not differ between the three groups.

CONCLUSIONS

There is an indication that adherence to guidelines on methotrexate dosage may benefit patients with rheumatoid arthritis by improving disease activity without increasing toxicity. For definite proof, a randomised controlled trial comparing guideline supported dosing with usual care is needed.

Development of a computerized assessment of clinician adherence to a treatment guideline for patients with bipolar disorder

The adoption of treatment guidelines for complex psychiatric illness is increasing. Treatment decisions in psychiatry depend on a number of variables, including severity of symptoms, past treatment history, patient preferences, medication tolerability, and clinical response. While patient outcomes may be improved by the use of treatment guidelines, there is no agreed upon standard by which to assess the degree to which clinician behavior corresponds to those recommendations. This report presents a method to assess clinician adherence to the complex multidimensional treatment guideline for bipolar disorder utilized in the Texas Medication Algorithm Project. The steps involved in the development of this system are presented, including the reliance on standardized documentation, defining core variables of interest, selecting criteria for operationalization of those variables, and computerization of the assessment of adherence. The computerized assessment represents an improvement over other assessment methods, which have relied on laborious and costly chart reviews to extract clinical information and to analyze provider behavior. However, it is limited by the specificity of decisions that guided the adherence scoring process. Preliminary findings using this system with 2035 clinical visits conducted for the bipolar disorder module of TMAP Phase 3 are presented. These data indicate that this system of guideline adherence monitoring is feasible.

Measuring adherence to depression treatment guidelines in a VA primary care clinic

The primary objectives of this pilot study were to develop a measure of adherence for depression practice guidelines and to assess the degree to which providers and patients adhere to guidelines in a VA primary care setting. The Depression Guideline Measure (DGM) is based on three national guidelines. The DGM was used to review medical records of 111 patients with Patient Health Questionnaire (PHQ) scores >or=10. Interrater reliability for 15 of 19 DGM checklist items was excellent (kappa > 0.75). There was a broad range of adherence to guideline criteria: only 13.5% of patients were contacted for follow-up within 2 weeks, while 100% of providers documented follow-up plans. Forty percent of patients saw mental health providers, and 63% were prescribed antidepressants. A secondary objective of the study was to explore the relationship between guideline adherence and changes in PHQ scores. Among 51 patients who completed follow-up PHQs, no associations were detected. The results suggest that the DGM shows promise as a reliable measure of guideline adherence and that guideline criteria are frequently not met in busy primary care clinics. More research is needed to determine the validity of the DGM and the impact of guideline adherence on depression outcomes.

The pilot study of a telephone disease management program for depression

Most depressed patients are seen and treated exclusively by primary care clinicians. However, primary care patients with depression are often not adequately treated. The aims of this pilot study were to measure the impact of a telephone disease management program on patient outcome and clinician adherence to practice guidelines, measure the relationship of clinician adherence to patient outcome, and explore the measurement of patient adherence to clinician recommendations and its impact on patient outcomes. Thirty-five primary care practices in the University of Pennsylvania Health System were randomized to telephone disease management (TDM) or "usual care" (UC). All patients received a baseline and a 16-week follow-up clinical evaluation performed over the telephone. Those from TDM practices also received follow-up contact at least every 3 weeks, with formal evaluations at weeks 6 and 12. These interval contacts were designed to facilitate patient and clinician adherence to a treatment algorithm based on the Agency for Health Research and Quality (AHRQ) practice guidelines. Depressive symptoms evaluated with the Community Epidemiologic Survey of Depression (CES-D) scale as well as guideline adherence were the primary outcome measures. Sixty-one patients were enrolled in this pilot project. The overall effect for CES-D scores over time was significant, (P <.001), indicating that those participating in the trial (both TDM and UC groups) showed significant improvement. The interaction between intervention condition and time was also significant (P <.05), indicating that TDM patients improved significantly more over time than did UC patients. A greater proportion of TDM patients had CES-D scores <16 by Week 16 (66.7 versus 33.3%; chi(2), P <.05). The improvement in depression outcome for the TDM group was related to its impact on improving clinician adherence to depression treatment algorithms. The TDM pilot did not show a statistically significant effect on improving patient adherence to clinician recommendations, however. This preliminary data suggests that TDM for depression improves both clinician guideline adherence and patient outcomes in the acute phase of depression. The effect on patient outcome is at least partially explained by the effect of TDM on clinician adherence to depression treatment algorithms.
