Abstract
Background:
Providing high-quality advance care planning conversations for nursing home residents living with Alzheimer’s Disease and Related Dementias is a persistent challenge, but implementation of advance care planning interventions remains limited.
Objective:
This study explored barriers and enablers to implementing the Goals of Care video with nursing home staff and identified strategies to implement the video intervention.
Methods:
Nursing home administrators identified staff members involved in ACP discussions with residents and families. A research team member contacted these individuals by email or telephone. Fourteen staff members across six Florida nursing homes participated in in-person or virtual semi-structured interviews. A summative content analysis quantified the frequency of each CFIR construct coded as an enabler or barrier, with frequencies calculated at the nursing home level.
Results:
The primary enabler was the alignment of the Goals of Care video with nursing homes’ organizational mission. The most identified barrier was the video’s perceived length. Strategies to improve implementation included adapting materials, assessing readiness, and addressing site-specific challenges.
Conclusions:
Tailoring the Goals of Care video to the organizational context is essential. Addressing barriers, such as video concerns, while leveraging existing enablers can strengthen adoption and support more consistent advance care planning practices.

Introduction
Nursing homes are a common site of end-of-life care for residents living with advanced Alzheimer’s Disease and Related Dementias (ADRD; Orth et al., 2021) but providing high quality, person-centered, goal-concordant care is a persistent challenge in this setting. Nursing home residents living with advanced ADRD often experience infections and eating problems, contributing to burdensome end-of-life care (Mitchell et al., 2009) that can result in higher rates of potentially avoidable hospitalizations (Estrada et al., 2024; Xing et al., 2013). Advance care planning (ACP) is a process that supports discussions and decisions about goals and preferences for future care and treatment with residents and their family members (Rietjens et al., 2017; R. Sudore et al., 2017). When residents living with ADRD lose decisional capacity, family members are often asked to serve as proxy decision-makers. However, they are often unprepared to participate in decision-making regarding goals of care, resulting in feelings of uncertainty, strain, depression, and anxiety (Anderson et al., 2009; Azoulay et al., 2005; Fetherstonhaugh et al., 2017, 2019).
Prior literature indicates ACP interventions significantly improve the documentation of end-of-life care preferences (Ng et al., 2022), which can align care with the individuals’ treatment preferences. ACP interventions for residents living with dementia include educating family proxy decision-makers about goals of care choices and preparing them to communicate these preferences with nursing home staff. The Goals of Care (GOC), an ACP intervention, includes a video decision-aid, a decision-making guide, and a structured care plan meeting (Hanson et al., 2017). In a randomized control trial, it improved the quality of communication for family caregivers compared to usual care planning in North Carolina nursing homes. Residents were transferred to the hospital half as often, but overall survival was unchanged (Hanson et al., 2017). While the GOC intervention is effective, less is known about how to implement it in nursing homes.
Although ACP interventions have been found to be efficacious, less is known about detailed implementation strategies (Ng et al., 2022) associated with successful engagement. Even well-designed interventions may encounter contextual factors that hinder the intervention from being implemented as planned (Chisholm et al., 2022; Hawe et al., 2004; Palmer et al., 2019). For example, while nursing home staff perceived the GOC intervention positively in the original trail (Chisholm, Zimmerman, et al., 2018), the availability of nursing home resources influenced the level of implementation (Chisholm et al., 2022). Similarly, a large ACP nursing home pragmatic trial of an ACP video for long-stay residents with advanced illness which included those with ADRD had no significant effect on hospital transfers (Mitchell et al., 2018), which was particularly due to the high variability in implementing the intervention across nursing homes (Mitchell et al., 2018; Palmer et al., 2019). These findings suggest it is important to understand determinants that may hinder or enhance the use of ACP interventions to improve uptake. This study builds on existing literature by identifying barriers and enablers that may influence the implementation of GOC video. It advances current knowledge by conducting a pre-implementation assessment using the ACP pre-implementation tool, developed using the CFIR 2.0 framework, to systematically assess contextual factors that shape readiness for implementation. Additionally, this study identifies potential implementation strategies to mitigate identified barriers, offering actionable insight prior to intervention implementation. The aim of this study was to conduct a CFIR-guided content analysis to identify staff-perceived barriers and enablers to implement the GOC video in nursing homes, as well explore potential strategies to mitigate implementation barriers. This study was guided by the following research question: What staff perceived barriers and facilitators may influence the implementation of the GOC video in nursing homes?
Methods
Sample
The study was conducted with a convenience sample of six Florida nursing homes between September 2023 and May 2024. The 2021 LTCFocus data was utilized to obtain facility-level information on nursing homes (Brown University, 2021), including occupancy rate, bed size, payer mix, and racial composition of residents. Introductory emails providing an overview of the study were sent to nursing homes within a 25-mile radius of the University of Central Florida (N = 44), resulting in a 14% response rate. We did not find a significant difference between nursing homes that responded and non-responding facilities (table comparing responders to non-responders in Supplemental Material).
Nursing home administrators were asked to identify staff members involved in ACP discussions with residents and families for potential participation. Staff were contacted by a member of the research team by email or telephone and invited to participate in the study. A total of 14 nursing home staff were enrolled across the six facilities. In qualitative research, four to six groups are generally considered sufficient for capturing a board range of perspectives (Guest et al., 2017), and these groups are typically comprised of five to eight participants (Krueger & Casey, 2014). The sample size for this study is appropriate because we intentionally targeted key stakeholders involved in ACP discussions, which typically include 2 to 3 individuals in nursing homes. According to Hamilton and Finley (2019), engaging a smaller number of highly relevant participants allows for richer and more contextual insight, rather than the more superficial information that may result from larger but less targeted samples.
Prior to participating in the semi-structured interviews, each nursing home staff member received a copy of the informed consent and provided verbal consent. This study was approved by the University of Central Florida Institutional Review Board (IRB ID: Study00005646-). Each participant received an electronic $10.00 gift card after completing the semi-structured interview.
Researcher Characteristics and Reflexivity
Data collection was conducted by the study PI (LC). The PI has developed partnerships with Florida nursing homes and state organizations, but she is not a member of the nursing home staff. She has also conducted research primarily in nursing homes to improve quality and mitigate disparities through the implementation of evidence-based interventions. To support triangulation, multiple data sources were used, including the ACP pre-implementation checklist, which was used to collect information on barriers and enablers as well as text segments describing factors that may contribute to implementing the GOC video intervention. Additionally, secondary data, LTCFocus data, was used to assess nursing home characteristics. Attention to transferability was ensured through detailed documentation of the nursing home context and organizational processes, enabling readers to assess the applicability of the findings to other long-term care settings with similar structures or populations. Dependability was supported through systematic data collection procedures, consistent use of the checklist across sites. Confirmability was enhanced by grounding interpretations in the data and retaining clear links between raw data and analytic conclusions.
Data Collection
We used the Consolidated Framework for Implementation Research (CFIR) 2.0 framework (Damschroder et al., 2022), a well-established determinant framework. For this proposed study we focused on the three CFIR domains: (1) innovation-the intervention being implemented, (2) inner setting-environment where the intervention is being implemented, and (3) individual-roles and characteristics of individuals who are involved with the intervention. We excluded the outer setting and implementation process domains, as nursing home staff may have limited awareness of external factors influences on implementation, and the video was not actively implemented in facilities. Each selected domain includes several constructs that act as either barriers or enablers to successful implementation.
The CFIR 2.0 framework was used to guide the development of the ACP pre-implementation checklist (see Supplemental File for instrument). The checklist included columns that categorized CFIR 2.0 constructs as either enablers or barriers to implementing the GOC video, an 18-min decision aid intended to supplement but not replace ACP discussions. This video was developed using the International Patient Decision Aid Standards (Hanson et al., 2017). An additional column was included to capture additional information. To further inform the checklist, we reviewed existing literature to identify CFIR constructs related to ACP in nursing homes.
The study focused on perceptions of implementing the GOC video, a component of the GOC intervention used in the previously described successful trial (Hanson et al., 2017). Nursing home staff participated in 60-min semi-structured interviews-either individually or in groups, depending on the number of staff from each facility. The interviews were conducted in person at their facility in a room of their selection or via videoconferencing facilitated by a member of the research team and occurred between October 2023 and May 2024. Before the interviews, staff were informed that the study aimed to identify barriers and enablers to using the GOC video, as well as how constructs were barriers or enablers. Participants viewed the GOC video and then were interviewed using the ACP pre-implementation checklist. The checklist served as both a guide for the interviews to identify enablers and barriers to using the GOC video, and a tool for documenting field notes to describe detailed information on how constructs hindered or enabled use of the GOC video. For instance, staff were initially asked whether incorporating the GOC video into routine care would function as an enabler or barrier. Subsequently, they were asked to describe how the video could be integrated into routine practice within the nursing home, specifically addressing the work infrastructure construct.
Saturation was assessed by examining whether new themes emerged regarding how the CFIR constructs functioned as enablers or barriers to implementing the GOC video. This process was monitored iteratively, with the ACP pre-implementation checklists reviewed and coded concurrently with ongoing semi-structured interviews. After conducting a total of six interviews with one to six staff members in each group, the research team observed that the core themes related to CFIR constructs identified as enablers and barriers to implementing the GOC video were consistently repeated. No new insights emerged regarding how these constructs functioned as barriers or enablers (see Supplemental File for saturation table). Prior literature indicates qualitative research can reach saturation with approximately 7 to 19 interviews, particularly when the goal is to identify major themes (Hennink & Kaiser, 2022; Wutich et al., 2024). Furthermore, because our sample was smaller and more homogenous, based on staff discipline, we were able to achieve saturation with the six interviews.
Analysis
The coding process followed a deductive qualitative approach, guided by the ACP pre-implementation checklist to structure our analysis. After a research team member (LC) conducted semi-structured interviews with nursing home staff, two research team members (LC & WC) individually reviewed the staff responses regarding categorization of constructs as enablers or barriers at each nursing home. Prior to individual reviews, LC and WC discussed the process for using the ACP pre-implementation checklist to verify staff responses from the semi-structured interviews. Discrepancies were reviewed with the study PI (LC), who also reviewed the research teams’ categorization to ensure they aligned with participants’ descriptions of constructs. A summative content analysis (Hsieh & Shannon, 2005) was conducted to calculate the frequencies of each construct coded as an enabler or barrier using Excel at the nursing home level. If a construct was identified as both a barrier and enabler by staff at the same nursing home, it was coded as both. Text segments from nursing home staff, identified through the field notes from the ACP pre-implementation tool, were reviewed by the research team to explore how various constructs may facilitate or hinder the implementation of the GOC video. This analysis allowed investigators to determine which barriers and enablers were the most and least commonly reported among nursing homes, supported by direct quotes that illustrate these findings.
Implementation strategies were identified using the results from the Expert Recommendations for Implementation Change (ERIC) project (Powell et al., 2015) and the CFIR-ERIC Implementation Strategy Matching Tool, an Excel-based tool, to match CFRI barriers with ERIC implementation strategies. The CFIR-ERIC Matching tool includes CFIR constructs that align with up to 73 implementation strategies derived from ERIC
Results
The six nursing homes that participated in the study had a bed size range from 60 to 133 beds and had an average occupancy rate of 75%. The nursing homes represented a diverse mix in terms of payer status and racial composition of nursing home residents. Group sizes ranged from one to six staff members with an average of two respondents from each nursing home (see Table 1). Participants included registered nurses (n = 5), social workers (n = 4), nursing home administrators (n = 4), and physical therapists (n = 1) from the six nursing homes, responses are reported at the nursing home level.
Characteristics of NHs (N = 6) Describing Enablers and Barriers to Implementing the GOC Video Intervention.
Note. n = number of nursing home staff participants. N/A indicates percentages that are too small for reporting.
Participants reported nine CFIR 2.0 constructs as enablers and four CFIR 2.0 constructs as barriers to implementing the GOC video. The most commonly reported enabler included mission alignment or perceptions that implementing the GOC video aligns with the purpose of the organization. Additional enablers included having the physical and technology infrastructure in place to support implementing the GOC video (5 out of 6 nursing homes); an existing culture in the nursing home focused on recipient- and learning-centeredness (5 out of 6 nursing homes); a work infrastructure that supports ACP (4 out of 6 nursing homes); high quality formal and informal information sharing ( 4 out of 6 nursing homes); readiness to implement the GOC video ( 4 out of 6 nursing homes); and staff to facilitate the implementation of the video (4 out of 6 nursing homes).
Presenting the GOC video to residents/families was identified as a challenge by staff across the six nursing homes (innovation design). Most nursing home staff identified access to understandable health education (5 out of 6 nursing homes), resident and family readiness (4 out of 6 nursing homes), and different cultural and family backgrounds (4 out of 6 nursing homes) as barriers to implementing the GOC video with residents/families. See Table 2 for details.
CFIR 2.0 Constructs Reported as Enablers and Barriers to Implementing the GOC Video Intervention Across Nursing Homes.
Innovation Domain
Intervention Design
Although nursing homes are required to engage residents and families in ACP discussions, time constraints often limit the duration and content provided during the conversation. The GOC video may encounter similar implementation challenges, specifically because it is designed to be shown to families during resident care plan meetings. Staff across all six nursing homes identified the design of the intervention, particularly the video’s length, as a major barrier to sharing it with families during routine care planning. For example, a staff member at nursing home 1 reported, “Care plan meetings are only 15 minutes; we don’t have time to show the video during that meeting.”
“The video is way too long,” staff from NH 5.
Inner Setting
Physical, Information Technology, and Work Infrastructure
Nursing home staff reported having the space and equipment, such as conference rooms to present the video to residents and families. “Laptops can be used; we have the conference room for viewing” Staff member from nursing home 2
Additionally, nursing homes describe having the technology/infrastructure to support the implementation of the GOC video, indicating that emails are an effective method for sharing the video with families.
“Already send an email prior to care plan meetings.” Staff member from NH 3 “Email system is good way to provide video to families. Facility website with monthly newsletter (physical and digital).” Staff member from nursing home 4
Staff also noted that discussions about advanced directives typically occur during new admissions, hospital returns, or quarterly follow-up. These moments are an opportunity to present the GOC video before the next care plan meeting. As indicated, “Social worker engages families about goals of advance care planning during the admission and quarterly follow-up.” Staff member from nursing home 6
Relational Connection/Communication and Culture
High quality formal and informal information sharing was identified as potential facilitators for implementing the GOC video in nursing homes. Interdisciplinary teams-typically composed of nursing, social work, physical therapy, and dietary-have a central role in resident care. Their combined expertise, along with physician involvement, can create opportunities to engage residents and families in discussions about the GOC video. Specifically, nurses and providers who have established rapport with residents are well-positioned to initiate and guide these conversations. As noted, “Nurses and providers are helpful with goals of care discussions.” Staff member at nursing home 4.
“Initial discussion with social worker and family. Interdisciplinary team follows up once initial goal is decided.” Staff member at nursing home 1
Recipient-and Learned-Centeredness
The GOC video is an opportunity to facilitate resident-centered goals of care discussions. The video also aligns with the organizational culture of nursing homes that emphasize both recipient- and learning-centered care.
“ACP is a priority based on residents needs”. Staff at nursing home 1 “Upon admission, nurse starts ACP conversations. Inquiring with patients’ family if advance directive exist, what can be put in place.” Staff at nursing home 2
Mission Alignment
Additionally, the video supports the mission of nursing homes to provide continuous high quality to care residents. A staff member at nursing home 4 stated, “Our mission is to serve and care for residents, modify care to ensure we are meeting needs.” Since nursing homes routinely provide opportunities for ACP discussions, the GOC video can easily be integrated into existing processes to support these conversations. Nursing home staff indicated, “Ready to implement. GOC video could be included as part of the process.” Staff member at nursing home 1
Individuals Domain
Implementation Facilitators
Implementation facilitators are individuals with expertise in ACP discussions who can support and guide the implementation process. Nursing home staff identified the following personnel as implementation facilitators when introducing the GOC video:
“Care plan members.” Staff from nursing home 3 “Social worker likes to build rapport before having ACP conversation. Team meeting with nursing, clinicians, and social work.” Staff from nursing home 4 “Interdisciplinary team doing morning meetings to identify next steps of need for ACP. Social worker will approach the family.” Staff from nursing home 1 “Social worker.” Staff from nursing home 5
While implementation facilitators were identified as an enabler to implement the GOC video, the majority of the perceived barriers were related to constructs under the individual domain, specifically the innovation deliverers or individuals who are directly receiving the innovation construct.
Innovation Deliverers/Recipients
Residents and families of residents living with ADRD may not be aware of the need to discuss goals of care or what to focus on during these discussions due to limited education about ACP discussions, which may limit the use of the GOC video in nursing homes. Additionally, staff may lack the training to provide high quality resident-centered ACP discussions. As noted by staff from nursing home 2, “Patients/families and staff need education on this topic.”
“Families typically do not come with this education.” Staff from nursing home 6 “The more education the better.” Staff from nursing home 4
Recipient Readiness
Some residents and families of residents living with ADRD may not be ready engage in discussions about goals of care with nursing home staff, which can also be related to the limited education provided about the disease, the disease progression, and advance care planning. Furthermore, the culture and background of residents may influence the implementation of the GOC video. Some examples include:
“Religion and culture are potential barriers.” Staff member at nursing home 3 “The GOC video would need to be in Spanish.” Staff member at nursing home 4
Implementation Strategies
The CFIR-ERIC Strategy Mapping Tool suggested several potential strategies to address the implementation of two of the three barriers identified by participants. We used prior literature to identify the primary strategies for the additional barrier (recipient readiness) that was not mapped on the tool (Powell et al., 2015; see Table 3). One potential key implementation strategy would be to promote the adaptability of intervention across nursing homes. Furthermore, developing and distributing diverse educational materials related to the GOC video could improve the use of the video. It may also be important to identify and prepare champions to lead the implementation of the GOC video. These champions could assess readiness and identify barriers and facilitators to implement the intervention. Creating a learning collaborative in the facility to allow families and staff to use resident data to promote ACP discussions supplemented by the GOC video is another potential strategy.

Discussion
Prior literature has highlighted the benefits of implementing ACP interventions such as the GOC video in nursing homes (Ng et al., 2022). However, translating evidence into clinical practice remains a challenge across healthcare settings. This pre-implementation study identified enablers and barriers to implementing the GOC video with families of residents living with ADRD, which varied across nursing homes, suggesting organizational context influences the implementation process. The results are consistent with previous studies showing that implementation of the ACP interventions differs across nursing homes based on organizational characteristics (Chisholm et al., 2022; Palmer et al., 2019). Focusing on delivering the core components of the intervention while using tailored implementation strategies to facilitate implementation could improve implementation across nursing homes.
Mission alignment emerged as a significant enabler, with all six nursing homes reporting that the GOC intervention aligned with their organization’s purpose. This finding supports the priority of nursing homes to focus clinical care on person-centered care or care provided in a manner that reflects the individuals’ preferences (Corazzini et al., 2016; Rosemond et al., 2012), which aligns with the process of ACP (R. L. Sudore & Fried, 2010). Formal and informal leadership shapes the organization’s mission. As such, they can play an important role embedding interventions into the organizations’ culture (Aarons et al., 2015; Brazil et al., 2024; Finucane et al., 2013). Furthermore, interventions that are easily integrated into the clinical workflow of nursing homes may improve implementation and uptake by staff because of their alignment with organization’s culture (Basinska et al., 2022; Chisholm, Zhang, et al., 2018; Palmer et al., 2019).
In contrast, the length of the video was identified as a universal barrier, staff consistently cited it was incompatible with the short duration of the care plan meeting. Nursing home staff reported that while the GOC video aligned with their workflow, they lacked the time to implement the video. This is unsurprising, as contextual factors related to staff shortages and time pressures have been identified as constraints when implementing other kinds of nursing home interventions (Aasmul et al., 2018; Flo et al., 2016; Palmer et al., 2019; Tappen et al., 2017). These findings highlight that nursing homes may perceive the GOC video as conceptually important but may encounter structural and workflow challenges that can limit feasibility
Other enablers and barriers varied across nursing homes. A culture of resident- and learning-centeredness, which includes having shared values around continual improvement and using resident-data to inform practice, was highlighted as an enabler in five out of the six nursing homes. This indicates that a person-centered philosophy is beneficial for ACP interventions. Person-centered care emphasizes putting residents at the center of planning (Brazil et al., 2024) and focusing on individualized care that addresses the residents’ preferences, needs, and values (Basinska et al., 2022). ACP interventions, like the GOC video, also focus on similar principles for ACP discussions with residents (R. L. Sudore & Fried, 2010).
Physical and technology infrastructure was also crucial, with most nursing homes reporting they have the necessary resources to support the GOC video implementation. Prior literature has found that nursing home resources impact intervention implementation (Chisholm et al., 2022; McCreedy et al., 2024; Palmer et al., 2019). High resource nursing homes may have the staff and technology needed to implement ACP interventions, like the GOC video. Consequently, while some nursing homes may have the infrastructure and culture to facilitate ACP practices, they may not be uniformly available and should not be assumed.
Barriers related to family readiness, access to understandable education, and the influence of cultural and linguistic differences were reported by four to five nursing homes, indicating that individual-level variation may complicate implementation of the GOC video. Similar to other studies, these barriers highlight the complexity of implementing ACP interventions in diverse and dynamic environments like nursing homes (Chisholm et al., 2022; Flo et al., 2016; Palmer et al., 2019; Tappen et al., 2017).
It is crucial to identify and develop implementation strategies that can mitigate existing barriers to ACP (Aasmul et al., 2018; Gilissen et al., 2017; Tappen et al., 2017). Few studies have explored effective strategies for implementing ACP interventions in nursing homes, which may limit their adoption. Flo et al. (2016) conducted a scoping review to assess ACP implementation and strategies in nursing homes, which found staff education was a key implementation strategy in prior studies. This finding aligns with the results in this study. However, our results suggest that additional implementation strategies may be necessary in the successful implementation of ACP videos in nursing homes. Further research is needed to explore and refine these approaches.
Limitations
This study has several limitations that should be considered when interpreting the findings. A potential study limitation was barriers and enablers were self-reported by nursing home staff, which may introduce social desirability and recall bias. Although we used the ACP pre-implementation checklist to try and understand how resident/family determinants may influence the use of the GOC video in nursing homes, we did not include the perspectives of residents/family caregivers. Additionally, we did not collect information on nursing home staffs’ previous experience or training conducting ACP discussions, it is unclear how such factors may have shaped their perceptions of implementing the GOC video. The sample of nursing home staff that participated in this study was a small convenience sample, and as such, the study findings may not be generalizable to other nursing homes and may have the potential for selection bias. Furthermore, Florida nursing homes may have contextual differences that may reduce the generalizability of the findings to other states. The results are presented at the nursing home-level, and we do not link quotes to specific staff characteristics. However, we interviewed staff from various disciplines who reported similar barriers, as such, comments cited may reflect general views of nursing home staff.
Conclusion
This study highlights the importance of understanding both the enablers and barriers to implementing ACP interventions, like the GOC video and offers a model for evaluating the pre-implementation of other ACP interventions in the nursing home setting. Implementing evidence-based ACP interventions can lead to better alignment of care with residents’ preferences contributing to improved resident satisfaction. By aligning the intervention with nursing homes’ mission of providing resident-centered care and ensuring they have the necessary resources, nursing homes may enhance the uptake and impact of the ACP interventions. However, complex or time-consuming interventions may not align with the workflow of nursing homes, which may create challenges with integrating ACP interventions into nursing homes and may limit the effectiveness of the intervention. By using tools like the ACP pre-implementation checklist to leverage identified enablers and address barriers through targeted implementation strategies, nursing homes can improve the adoption and effectiveness. Future research is needed to explore how different organizational contexts influence the implementation of ACP interventions. Additionally, studies should continue to explore these factors and refine strategies to ensure implementation in diverse nursing home settings.
