  <brief_summary>
    <textblock>
      The high prevalence of chronic illnesses is a serious public health problem in the U.S., and&#xD;
      more than 70 million adults age ≥50 have at least one chronic illness. Management of chronic&#xD;
      conditions requires long-term use of complex treatment plans and can cause unintended&#xD;
      consequences, such as increased risk of medication errors. Patient portals (PPs), a federally&#xD;
      supported health information technology (IT), can be especially helpful for patients with&#xD;
      chronic illnesses. Patients can now access their own health records and directly communicate&#xD;
      with care providers through PPs. Prior findings suggest a great potential for using PPs to&#xD;
      improve care quality, and the federal government funds healthcare organizations to implement&#xD;
      this tool nationwide. Despite the potential benefits, the overall PP adoption rate in the&#xD;
      U.S. is low. A lack of PP use among older adults has been addressed as a particular concern.&#xD;
      When only older adults who use the Internet are considered, however, their proportion of PP&#xD;
      use is similar to other age groups. A few studies also reported that older adults are&#xD;
      receptive to PPs. In general, older adults need additional support for learning to use PPs,&#xD;
      as they tend to be less familiar with technology. Currently, most older adults receive little&#xD;
      or no PP support from their providers. This is an important gap in the nation's health IT&#xD;
      initiative because without appropriate support, older adults will not be able to use this&#xD;
      robust health tool, missing an important opportunity to improve their health outcomes. In an&#xD;
      effort to fill this gap, the investigators developed and tested an older adult friendly&#xD;
      Theory-based Patient portal eLearning Program (T-PeP) to support older adults in using PPs&#xD;
      for their care. In the proposed feasibility study, the investigators plan to (Aim 1) optimize&#xD;
      and implement a vendor-agnostic T-PeP and conduct formative and process evaluations; and (Aim&#xD;
      2) assess the preliminary impact of T-PeP on PP use and selected outcomes (PP knowledge,&#xD;
      self-efficacy for PP use and health decision making, health communication, and medication&#xD;
      reconciliation). If successful, this study could directly affect quality of care provided to&#xD;
      older adults and the success of the national health IT initiative. Findings from this study&#xD;
      will also provide hospitals, vendors, and policymakers with in-depth information on older&#xD;
      adults' current PP usage patterns and other challenges in using various types of PPs at the&#xD;
      national level.&#xD;

  <detailed_description>
    <textblock>
      The high prevalence of chronic illnesses is a serious public health problem in the United&#xD;
      States, accounting for 70% of all deaths. Older adults are especially vulnerable; more than&#xD;
      70 million adults age ≥50 have at least one chronic illness (e.g., heart disease, diabetes).&#xD;
      Management of chronic conditions requires long-term use of multiple medications and complex&#xD;
      treatment plans, which can cause unintended consequences, such as increased risk of&#xD;
      medication errors. Engaging patients in their care and health decision-making processes is&#xD;
      vital for the provision of high quality care to people with chronic conditions. Until&#xD;
      recently, however, patients were not given access to their own health records and had to call&#xD;
      their providers' offices to communicate with them. In the past few years, the nation has made&#xD;
      unprecedented efforts to transform health care using information technology (IT). Through&#xD;
      secure patient portals (PPs), patients now can access their electronic health records (EHRs),&#xD;
      directly send eMessages to their providers, and request medication renewals online. They can&#xD;
      also involve their family caregivers in their care more efficiently. PPs are especially&#xD;
      helpful for patients with chronic illnesses, as they offer tools to manage health conditions.&#xD;
      With the Meaningful Use (MU) incentive payment program by the Centers for Medicare and&#xD;
      Medicaid Services (CMS), healthcare organizations nationwide are implementing PPs and making&#xD;
      them available to the public.&#xD;
&#xD;
      Prior findings demonstrated positive impacts of PPs on management of chronic conditions,&#xD;
      adherence to treatment, and patient-provider communication. Currently, PP adoption rates vary&#xD;
      depending on care organizations, but the overall nationwide adoption rate has been low&#xD;
      (26.8%). A lack of PP use among older adults has been addressed as a particular concern.&#xD;
      Based on 2014 national survey data, however, when only online users were considered, the&#xD;
      proportion of PP use in older adults was similar to other age groups (≥18 yrs, 32.2%; 50-64,&#xD;
      34.1%; ≥65, 29.8%). In a 2015 SeniorNet34 member survey (N=553; mean age, 73.6 yrs), 60.6%&#xD;
      (n=327) reported having at least one PP account. These findings indicate an excellent&#xD;
      potential for using PPs for the care of older adults (AHRQ's priority population36). Many&#xD;
      older adults, however, are not technologically savvy and need additional support. Currently,&#xD;
      most older adults receive little or no PP training support from their providers. This is a&#xD;
      critical gap in the nation's health IT initiative because without appropriate support, older&#xD;
      adults will not be able to use this robust health tool, missing an important opportunity to&#xD;
      improve their health-related outcomes.&#xD;
&#xD;
      In an effort to fill this gap, in our previous studies the investigators developed and tested&#xD;
      the older adult friendly Theory-based PP eLearning Program (T-PeP) to provide older adults&#xD;
      necessary support for using PPs. In the proposed feasibility study, the investigators will&#xD;
      optimize and implement the program in a large older adult online community, conduct&#xD;
      formative/process evaluation, and assess its preliminary impact on PP use and selected&#xD;
      health-related outcomes. T-PeP was developed based on self-efficacy theory to improve older&#xD;
      adults' use of PPs for managing their care and includes learning modules, discussion boards,&#xD;
      and other resources. Considering variations in the types and usability of PPs used by&#xD;
      patients nationwide, T-PeP was developed as a vendor-agnostic (&quot;not tied to a specific&#xD;
      vendor&quot;) program. The specific aims of the study are to:&#xD;
&#xD;
      Aim 1: Optimize and implement T-PeP in an older adult online community and conduct formative&#xD;
      and process evaluations (e.g., usability problems, barriers and facilitators for PP use, and&#xD;
      other practical issues).&#xD;
&#xD;
      Aim 2: Assess the preliminary impact of T-PeP on older adults' PP use and selected&#xD;
      health-related outcomes using a two-arm randomized controlled trial (RCT). Older adult online&#xD;
      users with chronic conditions (N=242, age ≥50) will be recruited from a large older adult&#xD;
      online community (SeniorNet.org).&#xD;
&#xD;
      H1. The intervention group participants will demonstrate greater improvement than the control&#xD;
      group at the end of T-PeP (3 weeks) and at 4 months in PP knowledge, self-efficacy for using&#xD;
      PPs and making health decisions, perceived patient-provider communication, and PP use&#xD;
      (enrollment, usage frequency).&#xD;
&#xD;
      H2. More participants in the intervention group than the control group will reconcile the&#xD;
      medications they are taking with the medications listed in their PP at 4 months.&#xD;
&#xD;
      This study could directly impact quality of care provided to older adults and the success of&#xD;
      a national health IT initiative by offering a critically missing component in the current PP&#xD;
      implementation process-patient support for the health IT (PP) designed for patients. Findings&#xD;
      from the study will also provide hospitals, vendors, and policymakers in-depth information on&#xD;
      older adults' current PP usage patterns and other challenges in using various PPs at the&#xD;
      national level, contributing to the improvement of PP technology and clinical practices. Once&#xD;
      the feasibility of the study is demonstrated, the vendor-agnostic T-PeP could be used widely&#xD;
      and incorporated into busy practices. The next R01 study will test its long-term effects on&#xD;
      health behavior and clinical outcomes, as well as care cost, using more diverse samples,&#xD;
      including practice settings and underserved populations.&#xD;

The high prevalence of chronic illnesses is a serious public health problem in the United
      States, accounting for 70% of all deaths. Older adults are especially vulnerable; more than
      70 million adults age ≥50 have at least one chronic illness (e.g., heart disease, diabetes).
      Management of chronic conditions requires long-term use of multiple medications and complex
      treatment plans, which can cause unintended consequences, such as increased risk of
      medication errors. Engaging patients in their care and health decision-making processes is
      vital for the provision of high quality care to people with chronic conditions. Until
      recently, however, patients were not given access to their own health records and had to call
      their providers' offices to communicate with them. In the past few years, the nation has made

      also involve their family caregivers in their care more efficiently. PPs are especially
      helpful for patients with chronic illnesses, as they offer tools to manage health conditions.
      With the Meaningful Use (MU) incentive payment program by the Centers for Medicare and
      Medicaid Services (CMS), healthcare organizations nationwide are implementing PPs and making
      them available to the public.

      Prior findings demonstrated positive impacts of PPs on management of chronic conditions,
      adherence to treatment, and patient-provider communication. Currently, PP adoption rates vary
      depending on care organizations, but the overall nationwide adoption rate has been low
      (26.8%). A lack of PP use among older adults has been addressed as a particular concern.
      Based on 2014 national survey data, however, when only online users were considered, the
      proportion of PP use in older adults was similar to other age groups (≥18 yrs, 32.2%; 50-64,
      34.1%; ≥65, 29.8%). In a 2015 SeniorNet34 member survey (N=553; mean age, 73.6 yrs), 60.6%
      (n=327) reported having at least one PP account. These findings indicate an excellent

      vendor") program. The specific aims of the study are to:

      Aim 1: Optimize and implement T-PeP in an older adult online community and conduct formative
      and process evaluations (e.g., usability problems, barriers and facilitators for PP use, and
      other practical issues).

      Aim 2: Assess the preliminary impact of T-PeP on older adults' PP use and selected
      health-related outcomes using a two-arm randomized controlled trial (RCT). Older adult online
      users with chronic conditions (N=242, age ≥50) will be recruited from a large older adult
      online community (SeniorNet.org).

      H1. The intervention group participants will demonstrate greater improvement than the control
      group at the end of T-PeP (3 weeks) and at 4 months in PP knowledge, self-efficacy for using
      PPs and making health decisions, perceived patient-provider communication, and PP use
      (enrollment, usage frequency).

      H2. More participants in the intervention group than the control group will reconcile the
      medications they are taking with the medications listed in their PP at 4 months.

      This study could directly impact quality of care provided to older adults and the success of
      a national health IT initiative by offering a critically missing component in the current PP
