Rethinking practitioner roles in chronic illness: the specialist, primary care physician, and the practice nurse

Controlled trial of problem-solving therapy and consultation-liaison for common mental disorders in general medical settings in Taiwan

OBJECTIVE

Common mental disorders (CMD) are prevalent high-impact illnesses seen in general medical settings worldwide. There has been no investigation on the efficacy of enhanced care in Chinese societies. The aim of this study was to compare the outcome of three interventions for treating CMD: usual care (UC), problem-solving therapy plus UC (PST-UC), and psychiatric consultation plus UC (PC-UC).

METHOD

The sample for this randomized controlled trial consisted of 254 patients with CMD being managed in general medical care settings. Clinical and functional assessments were done at baseline and at 16 weeks.

RESULTS

Two hundred six patients had complete data at 16 weeks (66 in the UC group, 63 in the PST-UC group, 77 in the PC-UC group). All patients had significant improvement on all scales over time, with no significant differences among the three treatment groups.

CONCLUSION

This trial failed to demonstrate the efficacy of enhanced care with consultation-liaison by mental health professionals for patients with CMD in general medical settings in Taiwan. Improved outcomes may require more integrated interventions.

Improving quality of care for mental illness in an uninsured, low-income primary care population

OBJECTIVE

We assessed if an ongoing, multifaceted quality improvement program improved mental health care in a low-income, uninsured primary care clinic.

METHODS

We reviewed the charts of 500 consecutive patients in 1999 and 500 consecutive patients in 2004 to compare the number of mental health visits; the percentage of patients with more than three follow-up visits; the percentage with > or = 1 visit with a prescribing provider and the percentage with a psychiatric medication prescribed. We also assessed whether patients with more than one charted mental illness received more care than patients with one mental illness.

RESULTS

Compared to 1999, patients in 2004 had significantly more visits in the first 120 days (acute phase) of treatment (3.16 vs. 4.81, P<.001) and more visits in up to 9 months post acute phase (3.76 vs. 4.88, P>.012). A higher percentage of patients in the acute phase (28.9% vs. 49.5%, P<.001) had three follow-up visits, saw a medical provider and received a prescription. Patients with multiple charted mental illnesses had more visits than patients with one mental illness in 2004 but not in 1999 (P<.001).

CONCLUSIONS

An ongoing, multifaceted intervention improved the quality of mental health care in a primary care population with a high prevalence of mental illness.

Supporting self-management for patients with complex medical needs: recommendations of a working group

Increasing numbers of persons live with complex chronic medical needs and are at risk for poor health outcomes. These patients require unique self-management support, as they must manage many, often interacting, tasks. As part of a conference on Managing Complexity in Chronic Care sponsored by the Department of Veterans Affairs, a working group was convened to consider self-management issues specific to complex chronic care. In this paper, we assess gaps in current knowledge on self-management support relevant to this population, report on the recommendations of our working group, and discuss directions for future study. We conclude that this population requires specialized, multidimensional self-management support to achieve a range of patient-centred goals. New technologies and models of care delivery may provide opportunities to develop this support. Validation and quantification of these processes will require the development of performance measures that reflect the needs of this population, and research to prove effectiveness.

Primary care - mental health collaboration: an example of assessing usual practice and potential barriers

Practice guidelines include recommendations for collaboration between primary care (PC) and mental health (MH) to improve the quality of depression management within primary care. There is little research, however, assessing usual care relationships between PC and MH providers, or providers' perceptions regarding collaboration. Based on the literature, we conceptualize a continuum of collaborative activities and strategies. We describe the extent of collaboration and perceived barriers in selected outpatient clinics. We conducted semi-structured interviews with 22 PC and MH clinical leaders from 10 outpatient facilities. Topics included existing referral, consultation, and collaboration practices between PC and MH, beliefs and barriers related to collaboration. Informants generally described good relationships between providers, and PC providers reported satisfaction with referrals to MH. Informal consultation also occurred, although it was not universal. There was little evidence of collaboration beyond this basic level. The leaders identified several potential barriers to collaboration, including inadequate staffing and resources for both services. In contrast with practice guidelines, the clinics we studied incorporated little collaboration with MH providers into PC management of depression. We identify strategies that can help overcome the barriers to collaboration that our informants most commonly identified.

Project IMPACT: a report on barriers and facilitators to sustainability

Project IMPACT is a collaborative care intervention to assist older adults suffering from major depressive disorder or dysthymia. Qualitative research methods were used to determine the barriers and facilitators to sustaining IMPACT in a primary care setting. Strong evidence supports the program's sustainability, but considerable variation exists in continuation strategies and operationalization across sites. Sustainability depended on the organizations' support of collaborative care models, the availability of staff trained in the intervention, and funding. The intervention's success was the most important sustainability factor, as documented by outcome data and through the "real world" experience of treating patients with this intervention.

Dentists' management of the diabetic patient: contrasting generalists and specialists

OBJECTIVES

We measured and contrasted general dentists' and periodontists' involvement in 3 areas of managing diabetic patients-assessment of health status, discussion of pertinent issues, and active management of patients--and identified and contrasted predictors of active management of diabetic patients.

METHODS

We conducted a cross-sectional mail survey of random samples of general dentists and periodontists in the northeastern United States during fall 2002, using lists from the 2001 American Dental Directory and the 2002 American Academy of Periodontology Directory. Responses were received from 105 of 132 eligible general dentists (response rate=80%) and from 103 of 142 eligible periodontists (response rate=73%).

RESULTS

Confidence, involvement with colleagues and medical experts, and professional responsibility were influential predictors of active management for periodontists (R2=0.46, P<.001). Variables pertaining to patient relations were significant predictors for general dentists (R2=0.55, P<.001).

CONCLUSIONS

Our findings permitted us to assess and compare general dentists' and periodontists' behavior in 3 realms--assessment of diabetic patients' health status, discussion of pertinent issues, and active management of diabetic patients--and to identify components of potentially effective targeted interventions aimed at increasing specialists' and generalist dentists' involvement in the active management of diabetic patients.

Systematic review of multifaceted interventions to improve depression care

OBJECTIVE

Depression is a prevalent high-impact illness with poor outcomes in primary care settings. We performed a systematic review to determine to what extent multifaceted interventions improve depression outcomes in primary care and to define key elements, patients who are likely to benefit and resources required for these interventions.

METHOD

We searched Medline, HealthSTAR, CINAHL, PsycINFO and a specialized registry of depression trials from 1966 to February 2006; reviewed bibliographies of pertinent articles; and consulted experts. Searches were limited to the English language. We included 28 randomized controlled trials that: (a) involved primary care patients receiving acute-phase treatment; (b) tested a multicomponent intervention involving a patient-directed component; and (c) reported effects on depression severity. Pairs of investigators independently abstracted information regarding (a) setting and subjects, (b) components of the intervention and (c) outcomes.

RESULTS

Twenty of 28 interventions improved depression outcomes over 3-12 months (an 18.4% median absolute increase in patients with 50% improvement in symptoms; range, 8.3-46%). Sustained improvements at 24-57 months were demonstrated in three studies addressing acute-phase and continuation-phase treatments. All interventions involved care management and required additional resources or staff reassignment to implement; interventions were delivered exclusively or predominantly by telephone in 16 studies. The most commonly used intervention features were: patient education and self-management, monitoring of depressive symptoms and treatment adherence, decision support for medication management, a patient registry and mental health supervision of care managers. Other intervention features were highly variable.

CONCLUSION

There is strong evidence supporting the short-term benefits of care management for depression; critical elements for successful programs are emerging.

Chronic disease management for depression in primary care: a summary of the current literature and implications for practice

OBJECTIVE

To review randomized controlled trials (RCTs) evaluating chronic disease management models for depression in primary care and to look at the implications for clinical practice in Canada.

METHODS

We reviewed all RCTs conducted between 1992 and 2006, including other reviews and analyses of pooled data. Using various search terms, we searched PsycINFO, Cinahl (1982 to May 2005), MEDLINE (1995 to 2005), EMBASE, The Cochrane Library, and PubMed.

RESULTS

There is conclusive evidence for the benefits of changing systems of care delivery to support the more effective management of depression in primary care. Most studies have demonstrated improved outcomes in terms of symptom reduction, relapse prevention, functioning in the community, adherence to treatment, community and workplace involvement, and satisfaction with care received.

CONCLUSIONS

Primary care practices need to examine how they can incorporate different concepts and models for managing depression. Components to consider include case registries, care managers or coordinators, treatment algorithms, follow-up and monitoring after a treated episode, care and relapse prevention plans, visits by psychiatrists, and training and ongoing education for all providers.

Models of care for treating late-life depression in primary care

The aim of this review is to highlight the need for treating late-life depression in primary care settings, review obstacles to doing so and introduce evidence-based models of depression care for older primary care patients. While interventions focusing on depression screening, provider education and referral to mental health specialists have had only limited success, several recent trials have demonstrated that programs in which primary care providers and mental health professionals effectively collaborate to treat depression using evidence-based treatment algorithms are more effective than usual care. Future research should address the problem of persistent depression, which has been identified in recent collaborative care studies, and focus on how to translate evidence-based approaches for late-life depression treatment into real world practice.

Collaborative care for depression in primary care. Making sense of a complex intervention: systematic review and meta-regression

BACKGROUND

The management of depression in primary care is a significant issue for health services worldwide. "Collaborative care" interventions are effective, but little is known about which aspects of these complex interventions are essential.

AIMS

To use meta-regression to identify "active ingredients" in collaborative care models for depression in primary care.

METHOD

Studies were identified using systematic searches of electronic databases. The content of collaborative care interventions was coded, together with outcome data on antidepressant use and depressive symptoms. Meta-regression was used to examine relationships between intervention content and outcomes.

RESULTS

There was no significant predictor of the effect of collaborative care on antidepressant use. Key predictors of depressive symptom outcomes included systematic identification of patients, professional background of staff and specialist supervision.

CONCLUSIONS

Meta-regression may be useful in examining "active ingredients" in complex interventions in mental health.

Management of pediatric mental disorders in primary care: where are we now and where are we going?

PURPOSE OF REVIEW

Pediatric mental disorders are among the most common disorders of childhood and are routinely seen in primary care. We review innovative management strategies, treatment technologies, and models of collaboration with behavioral health specialists in general medical settings. Our goal is to advance the integration of behavioral health services into primary care.

RECENT FINDINGS

The application of mental health interventions with proven efficacy holds great promise for youths with mental disorders. Unfortunately, traditional primary-care management of pediatric mental disorders is characterized by nonspecific counseling, low-dose prescribing, and referrals to specialty settings that are often not completed.

SUMMARY

The development, study, and refinement of new assessment and treatment technologies, supplemental treatments, and collaborative models of care delivery will be necessary to ensure more effective care for youths with mental disorders and their families. The promise of pediatric mental healthcare will not be fulfilled unless primary-care clinicians and behavioral health specialists forge new collaborative relationships that enhance the delivery of evidence-based care to affected children and their families.

Dissemination of evidence-based mental health interventions: importance to the trauma field

Randomized controlled trials have established the efficacy of psychotherapy and medication treatments for posttraumatic stress disorder (PTSD). Despite these advancements, many individuals do not receive guideline-concordant PTSD care. In an effort to advance dissemination of evidence-based PTSD treatments, the authors review several examples of dissemination efforts of mental health interventions. The first examples describe the dissemination of multifaceted collaborative care interventions for patients with depressive disorders and evidence-based interventions for patients with severe mental illness. The final example explores evolving efforts to adapt and disseminate interventions to acutely injured trauma survivors. For each example, the authors describe the problem with prior clinical approaches, the program to be disseminated, the barriers and levers to implementation and the progress in overcoming these barriers.

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.

The recovery process in major depression: an analysis employing Meleis' transition framework for deeper understanding as a foundation for nursing interventions

The number of persons with mental illness is increasing globally; despite this fact, nursing research on research-based interventions to prevent or minimize illness and increase quality of life is sparse. The purpose of this secondary analysis of men and women recovering from major depression (N = 25) was to gain a deeper understanding of the concept of transition in the recovery process associated with major depression as well as to develop and suggest nursing interventions that support the recovery process. The transition framework was useful, as it was describing the transition process as fluid, going back and forth, which was confirmed by the respondents' statements. Transition planning is a feasible way of supporting both the recovery process and health promotion, thus laying the foundations for a good quality of life.

Is the association between posttraumatic stress disorder symptoms and poor health due to a common familial or genetic factor?

OBJECTIVE

The objective of this study was to identify genetic, familial and environmental contributions to the association between posttraumatic stress disorder (PTSD) symptoms and poor health.

METHODS

A community sample of 1852 twin pairs was assessed for symptoms of PTSD [with the Impact of Events Scale (IES)] and self-reported global health status using a single five-level question. An ordinal logistic regression model estimated odds ratio/s (OR) for the association between PTSD and health status. Within-pair analysis assessed confounding by familial and genetic factors and adjusted for the possible confounding influence of age, sex, race, education and self-reported physician diagnosis of depression.

RESULTS

The IES was strongly and significantly associated with self-reported health [OR=1.8; 95% confidence interval (95% CI)=1.5-2.2; highest quartile vs. lowest quartile]. This association remained significant in within-pair analysis (OR=1.3; 95% CI=1.0-1.7), but after further adjustment for sociodemographics and depression, it was no longer significant (P(trend)=.17). Separate analysis by zygosity did not show differential effect in monozygotic or dizygotic pairs.

CONCLUSION

These findings suggest that the association between PTSD symptoms and poor health is, in part, due to familial confounding and sociodemographic factors. Little evidence of confounding by genetic factors was found. These findings suggest that early prevention efforts would have the greatest potential for improving poor health in PTSD-prone patients, whereas later intervention efforts directed at treating PTSD may have a more limited impact on improving poor health.

A model for a regional system of care to promote the health and well-being of people with rare chronic genetic disorders

People with rare, inherited chronic health conditions, such as hemophilia, face added physical, social, emotional, and fiscal challenges beyond those that are common to more prevalent chronic conditions. In 1975, a partnership among clinicians, consumers, and government agencies created a nationwide regional health delivery system that increased access to clinical care, prevention, and research, thereby improving health outcomes for people with hemophilia in the United States. Today, more than 130 Comprehensive Hemophilia Diagnostic and Treatment Centers in 12 regions serve 70%-80% of the nation's hemophilia patients. Health care leaders and advocates for other rare, expensive, chronic disorders may find that regionalization improves survival and reduces disability among affected populations. However, diverse and stable resources are needed to sustain such a model in our profit-oriented US health care arena.

Australian mental health reform: time for real outcomes

After 12 years of national mental health reform, major service gaps and poor experiences of care are common. The mental health community reports little progress in implementing its key priorities, such as expanded early-intervention programs, comanagement of people with mental health problems and related alcohol or substance misuse, and widening of the spectrum of acute care settings. We propose new national targets for reducing the social and economic costs of poor mental health; these include increased access to effective care, reduced suicide rates and improved rates of return to full social and economic participation. We detail specific service reforms designed to maximise the chance of achieving these targets, and prioritise youth health and integrated primary care programs. New independent and national reporting systems on the progress of mental health reform are urgently required.

Managing common mental health disorders in primary care: conceptual models and evidence base

The use of conceptual models can help to bridge the gap between research findings and policy development, illustrated here by the complex area of primary care mental health services

Role of specialists in common chronic diseases

Consultant care is currently available to only a small proportion of people with chronic illness. How can we enable many more people to benefit from specialist expertise?

Symptoms of major depression in people with spinal cord injury: implications for screening

OBJECTIVES

To provide psychometric data on a self-report measure of major depressive disorder (MDD) and to determine whether somatic symptoms are nonspecific or count toward the diagnosis.

DESIGN

Survey.

SETTING

Data from the National Spinal Cord Injury Statistical Center representing 16 Model Spinal Cord Injury Systems.

PARTICIPANTS

Eight hundred forty-nine people with spinal cord injury who completed a standardized follow-up evaluation 1 year after injury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The Patient Health Questionnaire-9 (PHQ-9), a measure of MDD as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition . We computed descriptive statistics on rates of depressive symptoms and probable MDD, evaluated internal consistency and construct validity, and analyzed the accuracy of individual items as predictors of MDD.

RESULTS

Exactly 11.4% of participants met criteria for probable MDD. Probable MDD was associated with poorer subjective health, lower satisfaction with life, and more difficulty in daily role functioning. Probable MDD was not related to most demographic or injury-related variables. Both somatic and psychologic symptoms predicted probable MDD.

CONCLUSIONS

The PHQ-9 has promise as a tool with which to identify probable MDD in people with SCI. Somatic symptoms should be counted toward the diagnosis and should alert health care providers to the likelihood of MDD. More efficient screening is only one of the quality improvement efforts needed to enhance management of MDD.

Primary care clinicians' use of standardized psychiatric diagnoses

OBJECTIVE

Treatment of child mental health (MH) problems should be informed by psychiatric diagnosis. Whether primary care clinicians (PCCs) use standardized psychiatric diagnostic criteria to direct the treatment of child MH problems is unknown. This study investigated PCCs' use of Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria during office visits.

METHODS

The data were obtained from 3674 children ages 4-15 years who were recognized as having one or more MH problems during office visits by clinicians participating in the Child Behaviour Study. Parents completed questionnaires before seeing the clinician. Clinicians completed a survey after the visit. The primary outcome was whether PCCs used standardized criteria to generate a diagnosis for children with recognized MH problems.

RESULTS

Clinicians used DSM criteria in 23% of visits in which a psychosocial problem was recognized, and 57% of PCCs reported no use of DSM. DSM criteria were used most frequently (38% of visits) when PCCs reported attention problems. Medications were much more likely to be prescribed during visits when PCCs diagnosed using DSM criteria (63% of visits vs. 19% when criteria were not used). However, only 51% of psychotropic medication prescriptions were based on a DSM diagnosis.

CONCLUSIONS

Clinicians used standardized criteria infrequently, and primarily to diagnose attention problems.

Case management for patients with poorly controlled diabetes: a randomized trial

PURPOSE

To evaluate the effects of a collaborative case management intervention for patients with poorly controlled type 2 diabetes on glycemic control, intermediate cardiovascular outcomes, satisfaction with care, and resource utilization.

METHODS

We conducted a randomized controlled trial at two Department of Veterans Affairs Medical Centers involving 246 veterans with diabetes and baseline hemoglobin A(1C) (HbA(1C)) levels >or=7.5%. Two nurse practitioner case managers worked with patients and their primary care providers, monitoring and coordinating care for the intervention group for 18 months through the use of telephone contacts, collaborative goal setting, and treatment algorithms. Control patients received educational materials and usual care from their primary care providers.

RESULTS

At the conclusion of the study, both case management and control patients remained under poor glycemic control and there was little difference between groups in mean exit HbA(1C) level (9.3% vs. 9.2%; difference = 0.1%; 95% confidence interval: -0.4% to 0.7%; P = 0.65). There was also no evidence that the intervention resulted in improvements in low-density lipoprotein cholesterol level or blood pressure control or greater intensification in medication therapy. However, intervention patients were substantially more satisfied with their diabetes care, with 82% rating their providers as better than average compared with 64% of patients in the control group (P = 0.04).

CONCLUSION

An intervention of collaborative case management did not improve key physiologic outcomes for high-risk patients with type 2 diabetes. The type of patients targeted for intervention, organizational factors, and program structure are likely critical determinants of the effectiveness of case management. Health systems must understand the potential limitations before expending substantial resources on case management, as the expected improvements in outcomes and downstream cost savings may not always be realized.

Are effects of depression management training for General Practitioners on patient outcomes mediated by improvements in the process of care?

BACKGROUND

Depression treatment by General Practitioners (GPs) and patient outcomes improved significantly after a comprehensive 20-h training program of GPs. This study examines whether the effects on patient outcomes are caused by the improvements in the process of care.

METHODS

Seventeen GPs participated in the training program. A pre-test-post-test design was used. A total of 174 patients (85 pre-test, 89 post-test) aged 18-65 met ICD-10 criteria for recent onset major depression. The main indicator of mediation was a drop in training effect size (eta2) on patient outcome after adjustment for individual and combined process of care variables. We evaluated depression-specific (recognition, accurate diagnosis, prescription of antidepressant, adequate antidepressant treatment) and a non-specific process of care variable (communicative skillfulness of the GP) as well as the combination of adequate antidepressant treatment and communicative skillfulness. Patient outcomes were assessed at 3 months and consisted of change in severity of symptomatology, level of daily functioning and activity limitation days from baseline.

RESULTS

Depression-specific interventions mediated up to one third of the observed improvement in patient outcome. 'Adequate dosage and duration of an antidepressant' explained 36% of the training effect on patient outcome (eta2 from 0.044 to 0.028). 'Communicative skillfulness of the GP' only was a weak mediator (18% explained; eta2 from 0.044 to 0.036). However, the combination of both, that is adequate antidepressant treatment by a communicative skillful GP, proved to be the strongest mediator of the observed training effect on patient outcomes (59% explained; eta2 from 0.044 to 0.018).

LIMITATIONS

The training effects on patient outcomes in this sample were small. Hence, the scope for mediation was limited.

CONCLUSION

GP communication skills are important to enhance depression-specific interventions in bringing about improvements in patient outcomes and should be addressed in GP training programs for the treatment of depression.

Primary mental health workers in child and adolescent mental health services

BACKGROUND

The interface between primary care and specialist services is increasingly seen as crucial in the effective management of child and adolescent mental health (CAMH) problems. In the United Kingdom, a new role of primary mental health worker (PMHW), has been established in order to achieve effective collaboration across the interface through the provision of clinical care in primary care settings and by improving the skills and confidence of primary care staff. However, little is known about the development of this innovative role in service contexts. Issues raised during the early stages of implementation may have important implications for the preparation and development of professionals who undertake the role.

AIMS

The aim of this paper is to report on a study that examined key issues in implementation of the PMHW role in six health authorities in England.

METHODS

Case study evaluation was conducted, using thematic analysis of 75 qualitative interviews with key stakeholders from different professions (e.g. PMHWs, general practitioners, health visitors, psychiatrists and service managers) and representing different sectors (primary care, specialist services and community child health services).

FINDINGS

The study identified three models of organization (outreach, primary care-based and teams). Each was associated with different advantages and disadvantages in its effects on referral rates to specialist services and the development of effective working relationships with primary care providers. Problems associated with accommodation and effective integration of PMHWs with specialist services, and tensions caused by the two different roles that PMHWs could undertake (direct clinical care vs. consultation-liaison) were common across all sites.

CONCLUSIONS

The PMHW role is an important development that may go some way towards realizing the potential of primary care services in CAMH. The implementation of new roles and models of working in primary care is complex, but may be facilitated by effective planning with primary care providers, clear goals for staff, and a long-term perspective on service development.

The Surgical Nosology In Primary-care Settings (SNIPS): a simple bridging classification for the interface between primary and specialist care

BACKGROUND

The interface between primary care and specialist medical services is an important domain for health services research and policy. Of particular concern is optimising specialist services and the organisation of the specialist workforce to meet the needs and demands for specialist care, particularly those generated by referral from primary care. However, differences in the disease classification and reporting of the work of primary and specialist surgical sectors hamper such research. This paper describes the development of a bridging classification for use in the study of potential surgical problems in primary care settings, and for classifying referrals to surgical specialties.

METHODS

A three stage process was undertaken, which involved: (1) defining the categories of surgical disorders from a specialist perspective that were relevant to the specialist-primary care interface; (2) classifying the 'terms' in the International Classification of Primary Care Version 2-Plus (ICPC-2 Plus) to the surgical categories; and (3) using referral data from 303,000 patient encounters in the BEACH study of general practice activity in Australia to define a core set of surgical conditions. Inclusion of terms was based on the probability of specialist referral of patients with such problems, and specialists' perception that they constitute part of normal surgical practice.

RESULTS

A four-level hierarchy was developed, containing 8, 27 and 79 categories in the first, second and third levels, respectively. These categories classified 2050 ICPC-2 Plus terms that constituted the fourth level, and which covered the spectrum of problems that were managed in primary care and referred to surgical specialists.

CONCLUSION

Our method of classifying terms from a primary care classification system to categories delineated by specialists should be applicable to research addressing the interface between primary and specialist care. By describing the process and putting the bridging classification system in the public domain, we invite comment and application in other settings where similar problems might be faced.

Pediatrician attitudes and practices regarding collaborative asthma education

Pediatric practices were surveyed in 10 regions of the country to determine physician attitudes and practices regarding approaches to asthma education. Many physician respondents thought that nurses were just as effective as physicians in providing asthma education. In almost all practices a physician was involved; in two thirds of practices, an allied health professional; and in almost half of practices (48%), a registered nurse was involved. The type of healthcare professional involved in education was not associated with percentage of patients with Medicaid insurance, practice ownership, or setting. Given the multidisciplinary approach to education in many pediatric practices, quality improvement efforts to enhance asthma education by pediatric practices could be further enhanced by directly involving allied health professionals who practice in primary care settings.

Specialist outreach clinics in primary care and rural hospital settings

BACKGROUND

Specialist medical practitioners have conducted clinics in primary care and rural hospital settings for a variety of reasons in many different countries. Such clinics have been regarded as an important policy option for increasing the accessibility and effectiveness of specialist services and their integration with primary care services.

OBJECTIVES

To undertake a descriptive overview of studies of specialist outreach clinics and to assess the effectiveness of specialist outreach clinics on access, quality, health outcomes, patient satisfaction, use of services, and costs.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care (EPOC) specialised register (March 2002), the Cochrane Controlled Trials Register (CCTR) (Cochrane Library Issue 1, 2002), MEDLINE (including HealthStar) (1966 to May 2002), EMBASE (1988 to March 2002), CINAHL (1982 to March 2002), the Primary-Secondary Care Database previously maintained by the Centre for Primary Care Research in the Department of General Practice at the University of Manchester, a collection of studies from the UK collated in "Specialist Outreach Clinics in General Practice" (Roland 1998), and the reference lists of all retrieved articles.

SELECTION CRITERIA

Randomised trials, controlled before and after studies and interrupted time series analyses of visiting specialist outreach clinics in primary care or rural hospital settings, either providing simple consultations or as part of complex multifaceted interventions. The participants were patients, specialists, and primary care providers. The outcomes included objective measures of access, quality, health outcomes, satisfaction, service use, and cost.

DATA COLLECTION AND ANALYSIS

Four reviewers working in pairs independently extracted data and assessed study quality.

MAIN RESULTS

73 outreach interventions were identified covering many specialties, countries and settings. Nine studies met the inclusion criteria. Most comparative studies came from urban non-disadvantaged populations in developed countries. Simple 'shifted outpatients' styles of specialist outreach were shown to improve access, but there was no evidence of impact on health outcomes. Specialist outreach as part of more complex multifaceted interventions involving collaboration with primary care, education or other services was associated with improved health outcomes, more efficient and guideline-consistent care, and less use of inpatient services. The additional costs of outreach may be balanced by improved health outcomes.

REVIEWER'S CONCLUSIONS

This review supports the hypothesis that specialist outreach can improve access, outcomes and service use, especially when delivered as part of a multifaceted intervention. The benefits of simple outreach models in urban non-disadvantaged settings seem small. There is a need for good comparative studies of outreach in rural and disadvantaged settings where outreach may confer most benefit to access and health outcomes.

Impact of a Collaborative Care Model on Depression in a Primary Care Setting: A Randomized Controlled Trial

To measure the effects of a collaborative care model that emphasized the role of clinical pharmacists in providing drug therapy management and treatment follow-up to patients with depression, we conducted a randomized controlled trial at a staff model health maintenance organization. We compared the outcomes of subjects treated in this collaborative care model (75 patients, intervention group) with subjects receiving usual care (50 patients, control group). After 6 months, the intervention group demonstrated a significantly higher drug adherence rate than that of the control group (67% vs 48%, odds ratio 2.17, 95% confidence interval 1.04-4.51, p=0.038). Patient satisfaction was significantly greater among members randomly assigned to pharmacists' services than among controls, and provider satisfaction surveys revealed high approval rates as well. Changes in resource utilization were favorable for the intervention group, but differences from the control group did not achieve statistical significance. Clinical improvement was noted in both groups, but the difference was not significant. Clinical pharmacists had a favorable effect on multiple aspects of patient care. Future studies of this model in other health care settings appear warranted.

Public health context of women's mental health research

As more attention is directed to the mental health care of women, sex and gender differences in research design and in regulatory policies have interfaced with clinical care and public policy. An emphasis on women's mental health issues in the provision of treatment and care as well as the design of large-scale screening strategies to identify and treat women with mental disorders promises to be effective public health approaches to reducing the burden of mental illness in women. The past decade has seen increased emphasis on women's mental health and sex/gender differences in the federal sector and in the research community. Federal regulations (summarized in the NIH Outreach Notebook) call for the inclusion of women and minorities in NIH-funded clinical research. The regulations also place emphasis on gender analysis of the results of clinical trials, in particular phase III trials, the findings of which are likely to influence practice. There has been substantial progress toward the goal of including women in research, but more remains to be done. A 2000 GAO report titled "Women's Health: NIH Has Increased Its Efforts to Include Women in Research" commended NIH for tracking the number of women in clinical research but the report also noted that relatively few NIH-funded studies, including major clinical trials, had reported findings by gender of study participants. This was seen as an impediment to progress in developing gender-based effective treatments. In the past decade, the women's health field has moved beyond an exclusive emphasis on women's reproductive function to one that defines health as a scientific enterprise to identify clinically important sex and gender differences in prevalence, etiology, course, and treatment of illnesses affecting men and women in the population as well as conditions specific to women. Nonetheless, for mental disorders, women's reproductive function and its impact on mental health conditions is still understudied. Based on the epidemiology of mental disorders, the course of mental disorders in women in relation to reproductive transitions remains an important issue for the mental health field because the burden of mental disorders, such as depression and anxiety, fall disproportionately on women of childbearing and childrearing age. The public health emphasis on women's mental health does not lessen the basic scientific opportunities to be had by a focus on gender and sex differences. A 2001 report of the Institute of Medicine titled "Exploring the Biological Contributions to Health: Does Sex Matter?" underscores the benefit to health care of looking for sex differences at the biological level. Basic and clinical neuroscience research is rapidly accruing a knowledge base that will provide information at the level of genes and cells of the influences of biological sex on mental health outcomes in both women and men. A focus on women's mental health and gender/sex differences research promises to yield improvement in treatments and services and thereby to improve the public health as well as to increase fundamental knowledge about the etiology and neurophysiology of mental disorders.

Implementing an effective intervention for problem drinkers on medical wards

Many medical inpatients have alcohol related problems but evidence of the feasibility of instituting a brief intervention is incomplete. An alcohol counsellor trained nurses on five general medical wards to screen patients routinely for alcohol problems. She counselled appropriate patients using one or two counselling sessions. Efficacy of the counselling was assessed at interview six months following the admission. We found that 19.6% of male and 4.8% of female medical patients were drinking more than 50 units (U) or 33 drinks per week (male) or 35 U or 23 drinks per week (female). Counselling, with one or two sessions led to a reduction from a median of 74 U (49 drinks) per week at admission to 26 U (17 drinks) per week at six months follow-up. A second counselling session after discharge showed no advantage over a single one administered while the patient was in the ward. The barriers to developing a successful alcohol screening and counselling service in medical wards can be overcome provided there is also adequate support and training of the ward nursing staff.

Management of chronic disease by patients

Chronic conditions dominate health care in most parts of the world, including the United States. Management of a disease by the patient is central to control of its effects. A wide range of influences in the person's social and physical environments enhance or impede management efforts. Interventions to improve management by patients can produce positive outcomes including better monitoring of a condition, fewer symptoms, enhanced physical and psychosocial functioning, and reduced health care use. Successful programs have been theory based. Self-regulation is a promising framework for the development of interventions. Nonetheless, serious gaps in understanding and improving disease management by patients remain because of an emphasis on clinical settings for program delivery, neglect of the factors beyond patient behavior that enable or deter effective management, limitations of study designs in much work to date, reliance on short-term rather than long-term assessments, and failure to evaluate the independent contribution of various program components.

The Institute of Medicine "Chasm" report: implications for depression collaborative care models

The Institute of Medicine report "Crossing the Quality Chasm: A New Health Care System for the 21st Century" describes the barriers in the American health care system to improving quality of care and outcomes of chronic illness. This article describes how depression collaborative care models as well as newer research aimed at organizational and economic issues have addressed these barriers in order to improve outcomes for patients with depression in primary care systems.

Improving primary care treatment of depression among patients with diabetes mellitus: the design of the pathways study

This paper describes the methodology of a population based study of primary care patients with diabetes mellitus enrolled in a health maintenance organization. The first goal was to determine the prevalence and impact of depression in patients with diabetes. The second goal was to randomize approximately 300 patients with diabetes and major depression and/or dysthymia in a trial to test the effectiveness of a collaborative care intervention in improving quality of care and health outcomes among patients with diabetes and depression.

A contemporary protocol to assist primary care physicians in the treatment of panic and generalized anxiety disorders

Anxiety disorders are prevalent in primary care practice and generate a significant excess of morbidity, health services utilization, and health care expenditures. Complexities in delivering effective care for such disorders have led to stepped collaborative care models that involve nonphysician care managers following guideline-based protocols under the direction of patients' primary care physicians and a medical specialist. With the goal of aiding colleagues attempting to improve the primary care for panic and generalized anxiety disorders, we detail the collaborative care strategy for treatment of these conditions used by our National Institute of Mental Health (NIMH)-funded clinical trial in which a telephone-based care manager performs timely, patient-specific clinical and case management tasks. We illustrate the clinical considerations underlying the steps taken to implement and then sustain our care manager intervention at four geographically dispersed primary care practices linked by a common electronic medical record system and the modifications made as we encountered clinical situations common to typical practice settings. This report serves to familiarize physicians contemplating use of a similar strategy for improving the quality of primary care for an anxiety disorder or any other chronic mental health condition.

Using nurse practitioners to implement an intervention in primary care for high-utilizing patients with medically unexplained symptoms

Patients with medically unexplained symptoms (MUS) often are a source of frustration for clinicians, and despite high quality biomedical attention and frequent diagnostic tests, they have poor health outcomes. Following upon progress in depression treatment approaches, we developed a multidimensional treatment protocol for deployment by primary care personnel. This multi-faceted intervention for MUS patients emphasized cognitive-behavioral principles, the provider-patient relationship, pharmacological management, and treating comorbid medical diseases. We deployed it in an HMO using nurse practitioners (NP) to deliver the intervention to 101 patients, while 102 controls continued to receive medical care from their usual primary care physician. Successful deployment of the intervention required training the NPs, continuing support for the NPs in their management of this difficult population, and establishing strong communication links with the HMO. This paper addresses the practical considerations of using primary care personnel to implement a complex intervention in primary care, and it includes a discussion of special challenges encountered as well as solutions developed to overcome them.

A three-component model for reengineering systems for the treatment of depression in primary care

Depression in primary care is a chronic disease. As with most chronic diseases, long-term adherence to treatment plans is problematic. Evidence-based systems of care address this problem, but persistence and dissemination of systems after testing is a new problem. The three-component model for the care of patients with depression is a system of widely applicable, easily transported strategies and materials to address dissemination. The three-component model provides a series of routines (processes for structured diagnostic and follow-up-care with a time line) and division of responsibility, including a role for a telephone care manager. In the three-component model, clinician and office education create a prepared practice that is predisposed to providing evidence-based depression management. Enabling elements include the telephone care managers, who are trained to promote adherence to a management plan, and a supervising psychiatrist. The key reinforcing element is care manager reports about patient response to treatment. The three-component model is bound together by a common depression diagnostic and severity measure that facilitates communication and treatment decisions.

Quality improvement report: Effect of a multifaceted approach to detecting and managing depression in primary care

PROBLEM

Need to improve the detection and management of depression in primary care.

DESIGN

Prospective, before and after study of changes in detection and management following attempts to introduce a chronic disease management approach.

BACKGROUND AND SETTING

Two representative general practices in the north east of England that differed markedly in resources available and populations served. KEY MEASURES OF IMPROVEMENT: Number of cases on a depression register, number of cases accurately diagnosed, adherence to own clinical management guidelines.

STRATEGIES FOR CHANGE

Multifaceted intervention to meet the needs of each practice modified by in-house steering group, including resources to develop a case register, an education and training programme on detection and management agreed by consensus, facilitation of meetings with secondary care staff, and support in developing a practice guideline.

EFFECTS OF CHANGE

Practice A (with six partners and serving a predominantly affluent white British population) improved case detection rate by 23%, reduced prescribing of sub-therapeutic doses of antidepressants by 36%, and adhered to the preferred treatment regimens. At Practice B (with three partners and two surgeries located in deprived urban inner city areas with high levels of unemployment and large ethnic minority populations) improvement in the sensitivity of case detection was accompanied by a reduction in specificity. The practice did not reach consensus on its own guideline and was unable to sustain the model.

LESSONS LEARNT

A simple practice based approach improved the detection and management of depression in a team familiar with the philosophy of chronic disease management, with the capacity to commit to the programme, and with a critical mass of team members being open to change. This model failed to affect depression management when staff engagement with the project was passive rather than active and the practice was less well resourced and served an economically deprived and ethnically diverse population.

Long-term effects of a collaborative care intervention in persistently depressed primary care patients

OBJECTIVE

A previous study described the effect of a collaborative care intervention on improving adherence to antidepressant medications and depressive and functional outcomes of patients with persistent depressive symptoms 8 weeks after the primary care physician initiated treatment. This paper examined the 28-month effect of this intervention on adherence, depressive symptoms, functioning, and health care costs.

DESIGN

Randomized trial of stepped collaborative care intervention versus usual care.

SETTING

HMO in Seattle, Wash.

PATIENTS

Patients with major depression were stratified into severe and moderate depression groups prior to randomization.

INTERVENTIONS

A multifaceted intervention targeting patient, physician, and process of care, using collaborative management by a psychiatrist and a primary care physician.

MEASURES AND MAIN RESULTS

The collaborative care intervention was associated with continued improvement in depressive symptoms at 28 months in patients in the moderate-severity group (F1,87 = 8.65; P =.004), but not in patients in the high-severity group (F1,51 = 0.02; P =.88) Improvements in the intervention group in antidepressant adherence were found to occur for the first 6 months (chi2(1) = 8.23; P <.01) and second 6-month period (chi2(1) = 5.98; P <.05) after randomization in the high-severity group and for 6 months after randomization in the moderate-severity group(chi2(1) = 6.10; P <.05). There were no significant differences in total ambulatory costs between intervention and control patients over the 28-month period (F1,180 = 0.77; P =.40).

CONCLUSIONS

A collaborative care intervention was associated with sustained improvement in depressive outcomes without additional health care costs in approximately two thirds of primary care patients with persistent depressive symptoms.

Role of the specialist in the treatment of asthma

The preponderance of literature supports the efficacy of specialist care for asthma. Not every patient with asthma needs to be treated by a specialist, however. An optimal health care delivery model for asthma (i.e. one that provides high quality care that is cost effective) requires some mix of primary and specialty services. A tiered model of care in which the primary care physician acts as the first point of contact and decision-maker with regard to referral and that includes asthma specialists, including allergists, pulmonologists, and other health care professionals with expertise in asthma, appears to be a reasonable solution. The number of studies that compare various models for organizing asthma care is limited, however. Thus, further research is needed to determine how best to align the roles of primary care physicians, allied health professionals, and subspecialists in order to ensure seamless communication and cost-effective care that is targeted to individual patient needs.

The changing nature of consultation-liaison in primary care: bridging the gap between research and practice

Consultation-liaison (C-L) psychiatry is hypothesized to be a model of interface between primary care and specialist mental health services with significant advantages over other models of organizing mental health care. However, there are significant complexities in the definition and evaluation of this model. As well as discussing the definition of C-L in primary care, this paper highlights the gap between models of traditional C-L that are popular in practice and the increasingly complex models (based on chronic disease management) evaluated in research studies. It is hypothesized that traditional C-L approaches and newer models use different mechanisms of change to achieve their goals. The former focus on the relationships between primary care and specialist professionals, while the latter highlight the importance of the development of effective systems of delivering care. Although the latter may be crucial in enhancing the "efficacy" and "effectiveness" of these models in terms of clinician behavior change and patient outcome, the former may be crucial in terms of "dissemination" and "implementation" of these models from research contexts to routine care settings.

Collaborative interventions for physically injured trauma survivors: a pilot randomized effectiveness trial

Posttraumatic behavioral and emotional disturbances occur frequently among physically injured hospitalized trauma survivors. This investigation was a pilot randomized effectiveness trial of a 4-month collaborative care intervention for injured motor vehicle crash and assault victims. As surgical inpatients, intervention subjects (N=16) were assigned to a trauma support specialist who provided counseling, consulted with surgical and primary care providers, and attempted postdischarge care coordination. Control subjects (N=18) received usual posttraumatic care. For all participants, posttraumatic stress disorder (PTSD) and depressive symptoms, episodic alcohol intoxication, and functional limitations were evaluated during the hospitalization and 1 and 4 months postinjury. Study logs and field notes revealed that over 75% of intervention activity occurred in the first month after the trauma. One-month post-trauma intervention subjects when compared to controls demonstrated statistically significant decreases in PTSD symptoms as well as a reduction in depressive symptoms. However, at the 4-month assessment, intervention subjects evidenced no significant improvements in PTSD and depressive symptoms, episodic alcohol intoxication, or functional limitations. Future larger scale trials of stepped collaborative care interventions for physically injured trauma survivors are recommended.
