Brief summary

The goal of this proposal is to develop and evaluate patient-centered care tools for autistic adults and their primary care providers (PCPs).

Detailed description

The goal of this study is to develop and evaluate patient-centered care tools for autistic adults and their primary care providers (PCPs). One tool will allow autistic adults and/or their supporters to provide individualized information to PCPs about how being on the spectrum affects their healthcare and possible strategies to facilitate quality care. Another tool will capitalize on the power of patient narrative to educate PCPs about autism. These tools and other resources will be housed on an interactive website for autistic adults, supporters, and PCPs. The research team will evaluate the feasibility and acceptability of using the new web-based patient-centered care tools with autistic adults and their primary care providers. This study will provide data for a future trial testing the effectiveness of these tools in improving the health of autistic adults by increasing patient-centered care and patient activation.

Interventions

BEHAVIORALUse of toolkit

Patient participants will be given access to the toolkit and will create a customized report for their provider. Team will send report to providers and ask them to schedule appointment with patient to discuss.

Design outcomes

Primary

MeasureTime frameDescription
Patient Satisfaction1 month after use of toolkitAutistic participants completed an online survey about their satisfaction with the tool, including if they feel the tool is useful, how they think the tool will affect their healthcare, if and how they plan to use it with providers, and if they would recommend it to others.

Secondary

MeasureTime frameDescription
Provider Satisfaction1-2 months after patient uses toolkitProviders participated in a brief survey to assess satisfaction with the toolkit. Items addressed overall satisfaction and if they would or would not use the tools with other patients.
Patient Use of Toolkit Components1 month after use of toolkitWe collected data on whether or not participants completed the Autism Healthcare Accommodations Tool (AHAT) survey and whether or not they allowed the research team to send a copy of the report to their primary care provider.
Change in Patient Satisfaction With Healthcarebefore and 1 month after use of toolkitPatients completed an 8-item instrument assessing satisfaction with their primary healthcare experiences. The scale was previously adapted from the 2007 Health Information National Trends Survey (HINTS). In the pre-intervention survey autistic participants were asked to think about their last visit with their primary care provider. We did not assess patient-provider communication for those who were participating via a proxy as we did not feel that a proxy could adequately rate how satisfied the patient was with communication. Only autistic participants who said they had seen their PCP since using the healthcare toolkit were re-asked these items in the post-intervention survey. Responses used a 5-point Likert scale with anchors of 1 - Strongly Disagree to 5 - Strongly Agree. We analyzed items by summing the responses into a composite score (range 8-40; higher scores indicate higher satisfaction). Cronbach's alpha = 0.92.
Change in Patient's Perceived Barriers to HealthcareBefore and 1 month after use of toolkitAutistic participants were presented with a list of 16 barriers to healthcare and asked which ones keep them from obtaining good care. We compared the total number of barriers endorsed by participants in the pre- and post-intervention surveys. The proxy version of the survey included a few modified items to differentiate between barriers faced by the autistic individuals and those faced by the supporter. Due to differences in the wording, we could not combine results from those who participated directly with those who participated by proxy. Only data from autistic adults who participated directly is shown.
Change in Patient Healthcare Self-EfficacyBefore and 1 month after use of toolkitAutistic participants completed a 21-item healthcare self-efficacy scale before and 1 month after use of the toolkit. The scale was created de novo for this study, based on our prior qualitative work. Items addressed aspects related to healthcare navigation (e.g. How confident are you that you can make an appointment with your healthcare provider when needed?), successful interactions with providers, (e.g. How confident are you that you can describe your symptoms or healthcare concerns to your provider?), and self-management (e.g. How confident are you that you can take medications the way you are supposed to take them?). Response options used a 4-point Likert scale with anchors of 0 - Not at all confident to 3 - Totally confident. We scored self-efficacy by adding responses from the 21 items, resulting in a possible range of 0 to 63, with higher scores corresponding to higher self-efficacy. Cronbach's alpha was 0.92.

Participant flow

Recruitment details

We recruited autistic adults via fliers, postings, and announcements targeted to autism and disability-related list-serves, organizations, and forums. We invited the autistic adult's primary care providers (PCPs) to participate if the patient gave permission for us to contact their provider and provided usable contact information.

Pre-assignment details

The total number of participants enrolled includes everyone who consented to participate. Some participants clicked yes to the online consent, but did not participate in the initial survey. The number of participants noted as Started in the Participant Flow module includes only those that took the initial survey.

Change in Patient Healthcare Self-Efficacy

Autistic participants completed a 21-item healthcare self-efficacy scale before and 1 month after use of the toolkit. The scale was created de novo for this study, based on our prior qualitative work. Items addressed aspects related to healthcare navigation (e.g. How confident are you that you can make an appointment with your healthcare provider when needed?), successful interactions with providers, (e.g. How confident are you that you can describe your symptoms or healthcare concerns to your provider?), and self-management (e.g. How confident are you that you can take medications the way you are supposed to take them?). Response options used a 4-point Likert scale with anchors of 0 - Not at all confident to 3 - Totally confident. We scored self-efficacy by adding responses from the 21 items, resulting in a possible range of 0 to 63, with higher scores corresponding to higher self-efficacy. Cronbach's alpha was 0.92.

Time frame: Before and 1 month after use of toolkit

Population: Participants completing pre- and post-intervention survey themselves (not via a supporter), who had complete data on the self-efficacy scales on both surveys.
