Comprehensive Self-management Support for COPD Patients

The study team will adapt and expand an effective model of asthma self-management support for patients with chronic obstructive pulmonary disease (COPD). In this new model, community health workers will comprehensively screen for and address barriers to effective COPD self-management, including maladaptive coping behaviors, and guide patients through home-based pulmonary rehabilitation. Feasibility of the new model will be assessed in preparation for a fully powered, multisite randomized trial.

Phase II will focus on intervention implementation and evaluation (months 13-36).

The research team will randomize 58 COPD patients (29 per arm) to the SaMBA-COPD intervention or an attention control and follow them for 9 months to assess health and self-management behavior (SMB) outcomes.

Intervention:

Step 1: Outreach and Engagement. The project manager will notify the City Health Works (CHW) supervisor when an eligible and consented patient is randomized to receive care the intervention and will provide the patient's name and contact information. The CHW will call the patient within 7 days of consent to schedule a home visit. The CHW will encourage caregivers to join all meetings.

Step 2: Intake. The CHW will perform an intake interview that includes collection of basic information about the patient and their health and healthcare, including medications, intended to enable them to understand their health problems and provide them with chronic illness self-management support.

Step 3: Symptom assessment, medication adherence, and inhaler technique. The CHW will assess the patients' symptoms, adherence to medications, and check inhaler technique following a standardized protocol, and correct errors in inhaler use if identified.

Step 4: SMB barrier screening with the Screener. The CHWs will assess barriers to good SMB that lie within 4 domains: 1) social context, 2) physical health and functioning, 3) cognitive factors, and 4) psychological factors. To assess elements in each domain, the study team will use questions drawn from validated surveys used in the study team's research and in the SAMBA screening tool. Screening questions are a part of the study intervention, of which they consented to in the research consent. Examples of barriers follow:

1. Social context. Factors include adequacy of social support, financial and access concerns (costs, insurance, pharmacy convenience), language and literacy skills, coping with illness, alcohol and drug use, and use of culturally-rooted therapies like herbals and spiritual remedies.
2. Physical health and functioning. These include physical functioning and medication concerns (e.g., side effects, multiple medications).
3. Cognition. The CHW will screen for cognitive impairment with the validated Quick mild cognitive impairment screen (QMCI) because cognitive impairment may challenge their ability to perform SMB.
4. Psychology. Factors include depression and anxiety, and maladaptive beliefs about COPD and COPD medications.

Step 5: Addressing identified barriers. Each identified barrier links to a menu of actions for the patient and CHW to employ to resolve or work around it. Other actions may be identified by patient or CHW and pursued if desired. Wherever appropriate, the CHW will engage the patient's physicians and or a social worker to enact some of the action steps. Examples of barriers follow:

1. Social context barriers. Examples of actions include enrolling the patient in the New York State pharmaceutical assistance program to reduce drug costs or ask physicians to consider generic or formulary approved alternatives. If retrieving or renewing prescriptions is a problem, the CHW may pick up the medication or arrange delivery. The CHW can contact the physician to request a renewal if needed, and refer the patient to a social worker for assistance with home aid services, entitlements, insurance matters, and assistance when second hand smoke is a problem.
2. Physical health and functioning barriers. Examples include asking the physician to consider reducing medicines if the patient finds the regimen too burdensome, requesting occupational or physical therapy to address physical limitations, or engaging the social worker to arrange transportation.
3. Cognition barriers. The study team will specifically target memory but also use strategies to compensate based on type of impairment, including medication organization, slower-paced and explicit verbal instructions, use of tangible external aids, repetition and teach-back, use of plain language, and guided imagery to reduce cognitive load. Such strategies have been shown to improve SMB in low-literacy populations. The CHW may have more frequent encounters (in-person, phone) with memory impaired patients. Daily cell phone text reminders are another option that patients can select when memory problems impact regular medication use.
4. Psychological barriers. The CHW will notify the PCP if a participant voluntarily divulges any feelings of depression or anxiety. The PCP may evaluate and treat or refer to a mental health specialist.

COPD action plan and medication rescue pack. The study team will obtain consent from each patient's primary care provider to have a pharmacist counsel patients about rescue medications (oral steroids and antibiotics, "rescue pack") to be used in the event of an exacerbation of COPD. This consent will be obtained at the time of obtaining consent from the physician to recruit the patient for study participation. If the physician provides consent to recruit the patient but refuses consent to counsel the patient about the rescue pack, the patient will receive all intervention components with the exception of rescue pack counseling by a pharmacist.

For patients for whom the study team have consent from the PCP to provide counseling about the rescue pack, the CHW will suggest to the patient that they meet with the pharmacist. The meeting will be voluntary. For patients who agree, a referral will be made to the pharmacist and a visit scheduled, to take place in a clinical setting. The pharmacist will counsel the patient on the use of the rescue pack. If the patient agrees to receive a rescue pack, the pharmacist will place an order in the Epic electronic health record for the rescue pack medications, then pend and route the order to the patient's PCP. The PCP can choose to sign the order, cancel or delete it. The pharmacist will check to determine whether the prescription order was signed by the PCP. If it was not, the pharmacist will assume that the physician does not wish to provide the patient a rescue pack prescription. If the prescription order was signed by the physician, the pharmacist will contact the patient 7-10 days later to determine whether the patient picked up the medication and to ensure that the patient understands when and how to use the medications appropriately, and will notify the CHW that the patient received the medications. The CHW will discuss the use of the rescue pack medications with the patient at subsequent encounters to ensure that they continue to understand how to use them appropriately. Should the patient use the medications, the CHW, pharmacist, and or patient will notify the PCP, who will be encouraged to follow up with the patient.

Step 6: Home-Based Pulmonary Rehabilitation Protocol (HBPR). HBPR will be available to all patients who are able to ambulate with or without an assistive device (cane or walker), regardless of supplemental oxygen use. If the patient expresses interest in HBPR, the CHW will schedule the appointment and accompany the patient and caregiver (if available) to a clinical practice at the Mount Sinai Hospital. The patient will undergo a standard evaluation by a licensed respiratory therapist employed by Mount Sinai Hospital to develop the HBPR prescription. The evaluation will have two components, assessment of aerobic capacity using the 6-minute walk test (6MWT), and an assessment of muscular strength using elastic resistance bands. Target exercise intensity for HBPR will be set at 60-80% of the maximum work rate achieved during the 6MWT, a conservative goal intended to achieve benefit while minimizing risk of fatigue and shortness of breath. The therapist will select an appropriate band for home use for strength training exercises. During the evaluation, the respiratory therapist will monitor the patient's oxygen saturation, blood pressure, heart rate, and respiratory rate.

During the home visit that follows, the CHW will provide a timer, a pedometer to measure steps, an elastic resistance band, and an exercise diary. They may also provide the patient with an ergo cycle to enable them to conduct the aerobic exercises sitting down if walking is too burdensome or the patient is considered to be at high fall risk. The CHW and patient will consider the space available for exercise, such as a hallway, common space in the building (e.g., lobby, gathering room, etc.), outdoors during favorable weather, and local facilities like senior centers or churches. Once the area for exercise is selected, the CHW will demonstrate the walking and resistance training routines and observe the patient perform them on his/her own. The two will set a schedule for exercising and post the schedule and instructions prominently in the home.

Resistance training will consist of a simple routine of upper extremity extension and abduction movements with the elastic band. Each movement will be performed in 3 sets of 10 repetitions (15 minutes). The walking routine will last 20-40 minutes and the patient's pace will be guided by an audible click from the timer that is set by the CHW. The patient will be asked to perform the complete exercise routine 6 days a week. The CHW will directly supervise the patient multiple times over the 6-month intervention period. She will call periodically to support the patient when she is unable to visit.

The respiratory therapist will oversee the HBPR work of the CHW. This will include reviewing all cases in person or by phone every 7-14 days. Patients will be asked to reduce the intensity of exercise or rest for 5-10 minutes if they develop an uncomfortable level of shortness of breath or fatigue, and to stop exercising if they have symptoms that cause distress or discomfort and do not resolve after rest. Low literacy education methods will be used to ensure their understanding and retention of these instructions. The CHW will maintain communication with the therapist by HIPAA compliant secure email and telephone to report patient performance, trouble shoot problems, and to receive continuing education.

Step 7: Follow-up and Maintenance. The CHW will recommend that in-person meetings occur 1, 4, 8, and 12 weeks after intake and telephone follow-ups weekly through week 8 and monthly thereafter until month 6 when the intervention ends. Calls may be made more often to cognitively impaired patients to enhance information retention. Importantly, the patient and CHW will have the flexibility to tailor the number and frequency of encounters as they see fit. During follow up the CHW will assess patients' progress with SMB, their goals, and their symptoms.

Step 8: Graduation. SaMBA-COPD patients will receive a certificate upon program completion.
