In Year 1, a transition of care model was designed and developed. This was achieved by gathering qualitative data through semi-structured interviews with (a) Hispanic/Latino patients with diabetes who had had a recent (within the past 3 months) hospitalization, and (b) outpatient and inpatient health care providers. The information collected provided a greater understanding of the challenges and barriers experienced by Hispanic/Latino adult patients while transitioning from the hospital to the community. In Year 2, the study will focus on pilot testing the new transition of care model. This will be accomplished by using a 2-arm approach and randomizing 32 adult Hispanic/Latino patients with diabetes who have been admitted to the hospital. One arm will enroll in the usual transition of care process and the second arm will enroll using the newly developed transition of care model. Figure 1 provides details of the pilot study framework including structure, process, and outcomes. The 2019 coronavirus (COVID-19) pandemic has led to unprecedented challenges within our health system, academic institution, community, and broader society. Given mandated physical distancing and national lockdowns, data collection was modified from face-to-face to remote data collection for Aim 1, using Zoom as the method accepted by our institution.
Study Aims
Our first aim is to develop a model for transition of care from the hospital to the community for Hispanic/Latino adult (≥18 years of age) patients with diabetes, taking into consideration patient and provider perspectives. Our second aim is to pilot test and determine the feasibility of a transition of care model for Hispanic/Latino adult patients (≥18years of age) with diabetes.
Participants and Inclusion Criteria
For aim 1, study participants included adult Hispanic/Latino patients with diabetes and health care providers. Inclusion criteria for patients are the following: (a) adult (age ≥18 years), and (b) self-identified Hispanic/Latino with a diagnosis of diabetes and a recent (within the past 3 months) hospitalization. There are no exclusion criteria based on health status, comorbidities, or other factors. Inclusion criteria for providers are the following: clinical and/or hospital provider (e.g., Doctor of Medicine [MD] or Osteopathic Medicine [DO], Nurse Practitioner [NP], Physician Assistant [PA]) currently practicing in the inpatient and/or outpatient setting.
For aim 2, participant inclusion and exclusion criteria are identical to those for Aim 1 but include an additional criterion: patients currently admitted to the hospital with anticipated discharge to the home setting.
Enrollment for aim 1 was initially intended to be accomplished by word of mouth and referral by local Hispanic/Latino organizations; however, to ensure that participants enrolled included those with a recent hospitalization, a purposeful sampling technique was used to identify potential participants using the health system’s Electronic Medical Record (EMR). This method was selected as it allowed for the identification and selection of information-rich participants and the most effective use of limited resources. Those meeting inclusion criteria were approached by telephone and screened to determine interest and obtain informed consent. Provider recruitment was initially to be accomplished by posting flyers at the target hospitals and clinics, and by word of mouth; however, due to restrictions imposed by the COVID-19 pandemic, word of mouth and emails were used as the contact methods.
Description of the Study Methods
This pilot and feasibility study was designed with two main goals:
-
Develop a new transition of care model based on data collected from participants (patients and providers) including but not limited to challenges and barriers to and facilitators of transition of care from the hospital to the community for adult Hispanic/Latino patients with diabetes.
-
Pilot test the newly developed a transition of care model to determine its feasibility and potential effect on ED visits and unplanned readmissions 30 days post-discharge.
Procedures
Aim 1: Patients and providers participated in one-on-one semi-structured interviews scheduled at a time and date convenient for participants. Initially, the interviews were designed to be in-person and face-to-face; however, due to the COVID-19 pandemic, restrictions were imposed on in-person, noncritical research-related meetings. Given physical distancing measures, national lockdowns, and other restrictions, the traditional face-to-face qualitative interview method was not possible, and interviews were conducted remotely using Zoom or by telephone. The intended recruitment goal was 12 patients and 8 providers or until data saturation was reached.
The semi-structured interviews were designed to gather information pertaining to patients’ and providers’ perspectives of the current transition of care of patients with diabetes from the hospital to the community setting. Questions were developed using three types of questions: engagement, exploratory, and exit (see Table 1). All participants provided written informed consent prior to their interview. Patients completed a short demographic questionnaire including age, preferred language, place of birth, years in the United States (if applicable), marital status, gender, insurance, diabetes type, years since diagnosis of diabetes, comorbidities (i.e., hypertension, hyperlipidemia, coronary artery disease, obesity, other), recent hospitalization within the past 30 days and year, visit to the ED within the past year, data regarding recent hospitalization, date of recent hospitalization, duration of most recent hospitalization, and education. Providers completed a short demographic questionnaire including age, preferred language, place of birth, years in the United States (if applicable), practice location, highest degree, years in practice, practice setting (inpatient vs outpatient), subspecialty, percentage of patients who are Hispanic/Latino, percentage of patients with diabetes, gender, ethnicity, and race.

New Direction
The COVID-19 pandemic has created many challenges for the Hispanic/Latino community, which has suffered from the pandemic disproportionally compared to the overall percentage of residents in the area. As of March 2021, there were 12,353 documented cases of the virus per 100k Hispanic/Latino people in NC [15]. During the peak of the pandemic in 2020, Hispanic/Latino people accounted for approximately 65% of the COVID-19 cases in Durham, North Carolina, although only 13% of the county’s overall population is Hispanic/Latino [16].
Given the multiple challenges brought on by the COVID-19 pandemic, the PIs found it necessary to adapt and modify the original study design. Under the guidance of the study sponsors/mentors, the study design was modified in several ways. First, it included conducting a community consultation with the university’s Clinical and Translational Science Institute/Community Engagement Research Initiative Core (CERI). This consultation provided additional data from the perspective of people living with and managing their diabetes while residing in the local community.
In addition to the consultation, the study design was changed from a randomized pilot study to a Plan-Do-Study-Act (PDSA) cycle framework. This model was chosen for several reasons: (a) the cycle can be used to test change over time and allows for adjustment during implementation to adapt to ongoing changes in health systems, (b) it facilitates implementation, and (c) it provides a more realistic assessment of the potential effect of a new transition of care to be implemented in the real word during challenging times [17].
The rationale for this modified approach was also informed by the fact that “the usual transition of care” was significantly altered to accommodate the changes implemented by hospitals during the pandemic due to increased numbers of patients admitted with COVID-19, limited beds and staff, and the overwhelming effect of the pandemic on health care systems in the country. These challenges rendered the “usual transition of care” no longer applicable, and it became apparent that we needed to adapt to the ongoing adjustments made by the health care system during the critical time of the pandemic.
Using the PDSA framework, enrollment will include 16 unique patients admitted to the hospital, followed by semi-structured interviews of a total of 5 patients to revisit and revise the transition of care model. Subsequently, test the revised version of the model with an additional 16 patients. At the end of enrollment, we plan to interview a total of 3 providers to explore their perspectives of the new model. Figure 2 depicts the new study design using the PDSA framework.
Statistical Analysis
For Aim 1, the PIs, both of whom are well experienced in qualitative research, transcribed the interviews into a Word document. The interviews were read multiple times for accuracy and emersion of the data and were coded into categories. The PIs reviewed the categories together and grouped the categories into common themes.
For Aim 2, descriptive statistics will be used to summarize participants’ demographic characteristics. Means and standard deviations will be used for continuous variables, frequencies, and percentages for categorical variables overall and by enrollment group. A paired t-test will be used to compare the two cohorts. The feasibility outcomes will be assessed to identify any differences between the groups and to refine the intervention.
