Utilization of Advance Care Planning for Homeless Adults: Case Studies.

Given the barriers to advance care planning (ACP) and low utilization of outpatient advance directives in hospital settings, it is unclear if ACP in primary care for adults who have experienced homelessness is effective and a valuable use of clinical time. As part of our ACP Project, we examined the feasibility and outcomes of ACP in primary care for patients who have experienced homelessness. We found that such efforts had significant impacts on patients' hospital care and allowed their wishes to be honored when they lost capacity for medical decision-making, particularly at the end of life. Here, we present six case studies demonstrating the outcomes of ACP in primary care for homeless adults and highlight lessons learned. To our knowledge, this is the first case series showing how ACP for homeless adults in primary care has been utilized during hospital care. Based on our findings, we believe that outpatient ACP even for the most socially vulnerable patients is feasible, often impactful, and should be integrated into routine primary care.

Assessing and Improving Zoster Vaccine Uptake in a Homeless Population.

The herpes zoster (shingles) vaccine is recommended for all adults aged ≥ 60 years without contraindications to prevent shingles and post-herpetic neuralgia. There are no published studies on zoster vaccination rates, barriers, or workflows in adults who have experienced homelessness. Due to barriers specific to this vaccine, including difficulty determining insurance coverage, high upfront costs, need for storage in a freezer, and under-prescription by physicians, uptake is lower compared to other recommended vaccines for older adults. To address these barriers, we developed a new approach of partnering our on-site primary care clinic in a transitional homeless shelter with a local pharmacy and offering vaccination on Shingles Immunization Days with a goal of matching or exceeding the national zoster immunization rate of 30.6%. Over a 3-year period, the live attenuated zoster vaccine was offered to 86% of eligible patients resulting in an immunization rate of 38.1%. This is higher than the estimated national rate but significantly lower than rates of tetanus (80.6%), pneumococcal (76.3%), and influenza (69.6%) vaccination in the same population, highlighting the unique obstacles to zoster immunization. Major reasons that patients were not immunized included lack of insurance coverage and patient refusal of all vaccines. Our findings demonstrate that homeless adults are interested in zoster vaccination and a model of on-site primary care in a shelter partnering with a pharmacy can successfully improve vaccine uptake in this population. Coverage of the new inactivated zoster vaccine under Medicare Part B could increase the national zoster immunization rate.

Feasibility of Advance Care Planning in Primary Care for Homeless Adults.

Objectives: As the homeless population ages, it is imperative to improve access to advance care planning (ACP) and document preferences in case medical decision-making capacity is lost. Methods: We implemented an ACP Project to discuss and document advance care plans with all patients aged 45 and older who received primary care at our adult Homeless Program clinics. Results: Over 14 months, ACP was discussed with 48% (n = 138) of the population and health care proxy (HCP) appointment with 91% (n = 125) of these patients. Most (62%; n = 77) appointed a HCP from personal relationships, though a significant minority (38%; n = 48) could not and were considered "surrogateless." End-of-life preferences varied. Approximately 20% of patients wanted to defer to a surrogate for each decision. Discussion: ACP is feasible in primary care for adults who have experienced homelessness and should be incorporated into routine care.
