Abstract

High levels of depressive symptoms are common and contribute to poorer clinical outcomes even in geriatric patients who are already taking antidepressant medication. The Depression CARE for PATients at Home intervention was designed for managing depression as part of ongoing care for medical and surgical patients. The intervention provides home health agencies the resources needed to implement depression care management as part of routine clinical practice.

The prevalence of geriatric depression is exceptionally high in home healthcare, with 1 in 7 older patients meeting full diagnostic criteria for major depression and as many as 1 in 3 suffering from clinically significant depression (Bruce et al., 2002; Knight & Houseman, 2008). This high rate of depression is consistent with home healthcare patients' significant medical burden, disability, and social isolation, factors that are both risk factors and outcomes of depression (Bruce, 2001; Bruce & Hoff, 1994; Bruce et al., 1994). Depressive symptoms at the start of care are generally clinically meaningful in that they are neither new nor transient (Bruce et al., 2002; Raue et al., 2003), are associated with suicide ideation (Raue et al., 2007), are associated with greater disability and medical burden (Bruce, 2002; Bruce et al., 2002), and predict adverse falls (Byers et al., 2008; Sheeran et al., 2004), early hospitalization (Sheeran et al., 2010), and excess services use (Friedman et al., 2009).

Clinically significant depression is often undetected or untreated in home healthcare patients (Brown et al., 2004; Brown et al., 2003; Bruce, 2002). The research group and others have demonstrated that nurses can be taught to successfully screen and refer patients with depressive symptoms for further evaluation (Brown et al., 2010; Bruce et al., 2007; Ell et al., 2005). Outcome and Assessment Information Set (OASIS) C broadened its data collection to include best practices related to assessing for signs and symptoms of depression and embedded the PHQ-2 for optional use. Data collection also includes care planning with the physician for interventions for the management of depressive symptoms and/or depression and the implementation of interventions. Consistent with the increased use of antidepressants in nursing homes (Fullerton et al., 2009), geriatric patients are increasingly beginning home healthcare treatment while already taking antidepressant medication and are being referred to home healthcare with or without a formal depression diagnosis (Shao et al., 2011).

Given the negative impact of depression on clinical care and medical and surgical outcomes in adult patients, the challenge for home healthcare is no longer merely case identification but the overall management of depression (Suter, Suter et al. 2008). Use of antidepressants does not necessarily indicate that a depressed patient is being treated adequately; indeed, the persistence of depressive symptoms despite ongoing antidepressant treatment suggests that a patient's treatment regimen requires review and possible change. Two of our studies have found that among symptomatic patients who are taking an antidepressant, one third are taking subtherapeutic doses (Bruce et al., 2007; Bruce et al., 2002). This finding is consistent with evidence in the general population that antidepressant prescribing is often not followed by ongoing care needed for guideline-consistent antidepressant treatment (often leading to changes in dosing, choice of medication, or augmentation) (Chen et al., 2010; Chen et al., 2010). This trend may be especially problematic in older and sicker patients where physicians may appropriately "start low, go slow" but then lack of follow-up may leave patients on subtherapeutic doses of antidepressants (Mojtabai & Olfson, 2008; Wright et al., 2009).

Research on elderly psychiatric patients with depression supports the efficacy of antidepressant medication, psychotherapy, and combined medication and psychotherapy treatment (Areán & Cook, 2002; Charney et al., 2003; Hollon et al., 2005). Interventions developed for primary care, such as Improving Mood: Promoting Access to Collaborative Treatment and Prevention of Suicide in Primary Care Elderly: Collaborative Trial, have demonstrated that ongoing depression care management (DCM) can improve patient care and outcomes for older adults (Bruce et al., 2004; Gilbody et al., 2006; Unützer et al., 2002). These models involve use of a trained care manager who offers guideline-based antidepressant medication recommendations to physicians, monitors patients' clinical status and side effects over time, and provides psychotherapy in some cases. DCM models of this sort are increasingly being implemented and sustained in routine primary care. But while DCM may be consistent with home healthcare practice, the interventions themselves were designed to fit the organization and the practice of primary care and not routine home healthcare, thereby undermining their effectiveness in the home setting (Ell et al., 2007).

This article describes an intervention, Depression CARE for PATients at Home (Depression CAREPATH), designed specifically for use in home healthcare in managing depression as part of ongoing care for medical and surgical patients. The CAREPATH intervention was designed to be delivered by nurses, physical therapists, and primary providers in the home. Training occupational therapists and other care providers to assist in the delivery further strengthens the intervention. The article describes the developmental process, as well as the major components of the intervention including a DCM protocol and resources for agencies to use to implement and support the use of the protocol in routine care. The article also provides preliminary evidence of the feasibility of using the Depression CAREPATH effectively.

Developmental Process

The Depression CAREPATH Intervention was developed in response to the need of Medicare-certified home health agencies (HHAs) for effective strategies to manage depressive symptoms that are commonly observed in their geriatric medical/surgical patients. The intervention was developed in partnership with the three HHAs that participated in our prior trial of an educational intervention to improve depression assessment and referral skills (Bruce et al., 2007). Together, agency clinicians and managers worked with the research group to review the routine practice of psychiatry home healthcare as well as DCM models used in other settings. Key functions of evidence-based DCM were identified and translated for consistency with home healthcare practice. The protocol was adapted to fit routine home care. We worked closely with the clinical leadership to field test and revise the intervention before conducting a demonstration trial that is described below.

A major conclusion of the workgroup was that the basic functions of DCM were consistent with routine home healthcare practice. These include: (1) assessing the severity and course of depressive symptoms over time; (2) coordinating depression treatment with physicians and mental health specialists; (3) managing antidepressant medications; (4) educating patients and their families, and (5) assisting patients in direct care and in becoming active in their treatment (Hennessey & Suter, 2009; Suter, Hennessey et al., 2008). Managing depression is similar to managing other chronic conditions such as diabetes, hypertension, or congestive heart failure (Hennessey & Suter, 2009). For patients with diabetes, for example, home healthcare nurses routinely assess blood sugar levels, review their medications, monitor treatment adherence, instruct patients in diet and exercise, and assist them in developing strategies for self-care.

In the primary care model, DCM is delivered by a designated "specialist"–commonly a nurse or social worker responsible for helping multiple primary care providers manage their patients' depression. Models generally require extra office visits by patients to meet in person with the specialist. Two problems for home healthcare implementation of this model have been identified. First, although home health psychiatric nursing has a long tradition of managing depression treatment, most agencies have few, if any, psychiatric nurses and do not have the capacity for delivering psychiatric home health for the large proportion of medical/surgical patients who suffer from depression. Second, adding mental health home visits to medical/surgical patients may add costs that will not be captured through Medicare reimbursement.

In the Depression CAREPATH for home healthcare, the functions of DCM are not transferred to a specialist. Rather, a decision was made to train every primary clinician within an agency to integrate standard DCM into routine visits and to consult with specialists as needed. This "every clinician does DCM" approach is consistent with the rest of home health nursing models in which clinicians are expected to manage an array of patients' problems in addition to the presenting, mostly acute, conditions and to consult experts as needed (American Nurses Association, 2008). The protocol includes the five basic functions listed above, including: (1) symptom assessment; (2) case coordination; (3) medication management, (4) education of patients and families, and (5) patient goal setting. The DCM protocol was designed to fit within the context of routine home visits. The training introduces DCM in the context of other chronic disease management, provides clear signals for consultation or referral, and teaches clinicians to interact with physicians more effectively. The DCM protocol and certification process is described more fully in a follow-up article (Part 2).

Infrastructure Support Key for Success

In developing the Depression CAREPATH intervention, it was also recognized that the effectiveness of a DCM protocol would depend upon agency support for its implementation. Thus, the Depression CAREPATH also includes guidelines and resources to help agencies develop the infrastructure needed to support the use of the DCM protocol in routine care. It was recognized that while the protocol is designed to fit routine home healthcare, each agency is unique. Part of infrastructure development, therefore, involves HHAs tailoring these guidelines to fit their own needs.

The major components of infrastructure development include:

1. Integration of Protocol into Agency Clinical Management System: To be effective, DCM should look, feel, and sound like routine practice. In simple terms, if an agency calls comparable clinical management protocols a different term such as "guidelines," "algorithms," or "co-steps", then we recommend that the agency rename the DCM protocol using the same terms. If an agency supports these protocols on paper, then the DCM protocol should also be supported by paper using the same colors, fonts, and so forth. More often, however, agencies will have electronic resources and will want to integrate the protocol into their software. Our group has integrated the protocol into numerous home health clinical management systems, either using the "end-user" functions (i.e., working with the agency information technology person) or with the commercial software company itself.

2. Case Coordination Guidelines: Like the management of other chronic diseases (Suter, Hennessey et al., 2008), clinicians are not expected to make treatment decisions about depression, but to identify cases where greater evaluation and/or treatment decision making is needed. As a rule of thumb, clinicians will be expected to contact the patient's physician when clinically significant depressive symptoms are first identified, when symptoms worsen or do not change over a course of antidepressant treatment, or in the case of problematic side effects. However, HHAs with psychiatric nurses or clinically trained social workers may decide to tailor the referral guidelines to integrate these resources into the chain of contact and consultation. HHAs need to develop and communicate to their clinicians clear guidelines for case coordination and referral prior to implementing DCM protocols.

3. Suicide Risk Protocol: Depression is the greatest risk factor for suicide in late life (Conwell & Thompson, 2008; National Institute of Mental Health, 2007), and research indicates that suicide ideation is more prevalent in home healthcare patients than most other groups of older adults (Raue et al., 2007). In addition, assessment of suicide risk is a component of DCM. Clinicians who are prepared with guidelines for evaluating and responding to different levels of suicide risk will be more comfortable and effective in not only identifying and working with suicidal patients but all depression care. Thus, every agency should have a suicide risk protocol that operationalizes both gradations of suicide risks and the steps that should be taken by nurses at each stage (Raue et al., 2006). This group has samples (Figure 1) and templates that can help agencies create their own. Agencies must always adapt such templates or preexisting suicide risk protocols to their own resources and circumstances.

4. Mental Health Resources: It is helpful in case coordination and discharge planning if the agency catalogues the mental health resources available in the communities that serve their patients. Such resources include emergency psychiatric services, short-term interventions, and ongoing psychiatric care.

5. Develop Supervision Procedures: Because DCM is integrated into routine practice, agencies should ensure that clinical supervisors understand the protocol and include a review of its use as part of clinician supervision and evaluation.

Demonstration of Feasibility

After field testing the Depression CAREPATH with our local agency partners, it was implemented in collaboration with Community Health Care Services Foundation, Inc. and four home care agencies that were distributed across four regions of NY State (Hudson Valley, Northeast, NYC and Western). Across the four agencies, a randomly selected group of nurses from each agency (total N = 68) were trained in the full DCM protocol. Clinicians were eligible for the study if they were Registered Nurses and employed full or part time. Patients were eligible for the study if they were age = 65, newly admitted to home healthcare, and English-speaking. Exclusion criteria included chart diagnoses of dementia, bipolar disorder, or psychotic disorders. Effective use of the DCM protocol by participating clinicians was ensured via weekly telephone calls with nurse supervisors.

Results: At the start of care over a 2-month period, 200 (29%) of the patients cared for by the DCM nurses screened positive for depression. When assessed with the full PHQ-9, 100 (50%) patients had symptoms consistent with a diagnosis of major depression and 86 (43%) had symptoms consistent with a diagnosis of minor depression. These data indicate overall rates of major depression and minor depression as 14.5% and 12.5%, respectively. These rates closely correspond with previous research data (Bruce et al., 2002).

In consultation with the research team, the Project Leader at each of the agencies supervised the intervention nurses in the use of the DCM protocol. Using the protocol's PHQ-9 scores to document the course of depression from start of care to discharge, 50 (50%) of the patients with symptoms of major depression fully remitted (i.e., no longer depressed) and an additional 23 (23%) improved significantly (i.e., 50% reduction in depressive symptoms). The majority (52; 60%) of patients with symptoms of minor depression also improved. Although we have no direct comparison of PHQ-9 data from patients who did not receive DCM, we do know that these outcomes are consistent with results of depression treatment trials (Entsuah et al., 2001). Further, when we compared the discharge OASIS among DCM patients to 193 similarly depressed patients receiving usual care, usual care patients were 33% more likely to remain depressed than DCM patients. Although not definitive, these preliminary data suggest that the Depression CAREPATH Intervention contributes to positive outcomes.

The research team visited each agency at the close of the project to discuss the experience with DCM nurses and administrators. The overall response from nurses about use of the DCM protocol was positive. Nurses reported that the protocol fit well within routine care. One noted that it "helped me become a better advocate for my patients' care". Many found that it became easier to talk to physicians and mental health professionals about depressed patients. And they were more likely to ask family members about patient depression. The leadership was also positive; one administrator reported that she had added the training modules "to the orientation for all new employees." They all appreciated that nurses were trained to communicate with physicians more effectively, a skill that transcended depression care. Another administrator noted that the "project provided a role model for how nurses can integrate evidence-based practice into their routine work."

Implications and Conclusion

The high prevalence of depression in geriatric home healthcare patients poses a challenge to patients' outcomes and high-quality care. Depressed patients are less adherent to other treatment regimens, experience more adverse advents, and have poorer outcomes (Byers et al., 2008; Friedman et al., 2009; Katon et al., 2010; Sheeran et al., 2004; Sheeran et al., 2010). High levels of depressive symptoms are clinically significant whether or not a patient has received a formal depression diagnosis or is already taking antidepressant medication. Like other chronic medical conditions, depressed home healthcare patients will benefit from good DCM.

The Depression CAREPATH intervention was designed in collaboration with HHA clinicians and administrators for use in home healthcare in managing depression as part of ongoing care for medical and surgical patients. The intervention includes both a DCM protocol designed for use during regular home visits as well as implementation tools for HHAs.

Our group has demonstrated the feasibility of using the DCM protocol as part of routine care and of integrating it into six commercial software programs. Based on the feedback from these agencies and preliminary data, we are conducting an NIH-funded randomized trial to test the effectiveness of the Depression CAREPATH in seven agencies, located in different regions of the country. In addition, resources are being developed so that the tools needed to implement and support Cornell's Depression CAREPATH intervention will be freely and openly available to HHAs seeking to use the tools.
