“…Because portal use may itself serve as a marker of patient engagement, additional studies are needed to confirm our findings and to explore other potential health benefits in a nephrology setting. For example, portals can be modified to include CKD educational information (17,75), medication safety checks in the setting of impaired renal function (76), dietary guidance (77), and checklists and reminders regarding kidney transplant evaluation (17). Randomized controlled trials are needed to overcome potential confounding due to patient-level variables (e.g., health literacy, patient activation) that we could not discern.…”

Background and objectives Electronic health record (EHR) patient portals allow individuals to access their medical information with the intent of patient empowerment. However, little is known about portal use in nephrology patients. We addressed this gap by characterizing adoption of an EHR portal, assessing secular trends, and examining the association of portal adoption and BP control (,140/90 mmHg).Design, setting, participants, & measurements Patients seen between January 1, 2010, and December 31, 2012, at any of four university-affiliated nephrology offices who had at least one additional nephrology follow-up visit before June 30, 2013, were included. Sociodemographic characteristics, comorbidities, clinical measurements, and office visits were abstracted from the EHR. Neighborhood median household income was obtained from the American Community Survey 2012.Results Of 2803 patients, 1098 (39%) accessed the portal. Over 87% of users reviewed laboratory results, 85% reviewed their medical information (e.g., medical history), 85% reviewed or altered appointments, 77% reviewed medications, 65% requested medication refills, and 31% requested medical advice from their renal provider. ConclusionWhile portal adoption appears to be increasing, greater attention is needed to understand why vulnerable populations do not access it. Future research should examine barriers to the use of e-health technologies in underserved patients with CKD, interventions to address them, and their potential to improve outcomes.

“…Features available for the SMS text platform have been previously described (6) and include the abilities to send the name of a medication by SMS text message and receive a response text informing the patient of the medication's safety in CKD with three potential responses: not safe in CKD, use with caution/speak with your health care provider, and safe in CKD. The PDA application platform allows users to search by the medication name or class (e.g., ibuprofen or pain medication).…”

“…In this study, we set out to build on prior scripted in-center usability testing, which has been previously reported (6), of a disease-specific application designed as a medication inquiry system (MIS) offering patients information on the safety of drugs in CKD. This study evaluates home-based usability of two mobile health MIS platforms, including short messaging service (SMS) texts or an application embedded in a personal digital assistant (PDA), and reports on the acceptance of the mobile health platform by usability participants.…”

Background and objectives Inappropriate medication use is common in the care of patients with CKD. The feasibility of a simple mobile health tool designed to advise patients on safe medication usage in CKD was examined.Design, setting, participants, & measurements Participants with predialysis CKD (defined as eGFR,60 ml/min per 1.73 m 2 ) in the Safe Kidney Care Cohort Study were recruited for home usability testing of a novel medication inquiry system between January and September of 2013. Testing was through two mobile platforms: (1) short messaging service text or (2) personal digital assistant (e.g., iPod Touch). Twenty participants (one half assigned to one device and one half assigned to the other device) were enrolled and received an in-center tutorial on device usage before the end of the study visit. Participants were subsequently mailed three sample pill bottles with the name of randomly selected medications and asked to input these medications into the medication inquiry system. The medication inquiry system response options were as follows: (1) safe in CKD, (2) not safe in CKD, (3) use with caution/speak with your health care provider, or (4) error message (for an incorrectly inputted medication). Participants were asked to record the response issued by the medication inquiry system for each medication sent for usability testing. A user satisfaction survey was administered after completion of the protocol.Results All participants owned a mobile telephone, but few owned a smartphone. Of 60 total medication queries, there were only three recorded errors, two of which occurred in the short messaging service texting group. Overall satisfaction with the application was high, with slightly higher satisfaction noted in the personal digital assistant group compared with the short messaging service group. ConclusionsThe mobile health medication inquiry system application had general ease of use and high acceptance across two platforms among individuals representative of the CKD population. Tailored mobile health technology may improve medication safety in CKD.

“…The test materials including the electronic application used in the present study were adapted from the applications used in the Safe Kidney Care™ cohort study (clinicaltrials.gov NCT 01407367) at the University of Maryland School of Medicine [4,5]. All study documents were based on guidelines from the US Department of Health and Human Services (HHS) [6].…”

Background and Objectives: Kidney transplant recipients are at increased risk for adverse safety events related to reduced renal function and polypharmacy. Health information technology tools have a precautionary role in improving safety in patients with kidney transplants who are at risk of drug-drug interactions. Materials and Methods: Usability testing of a drug-drug interaction inquiry system on a convenience sample of kidney transplant patients and their family members was conducted between January and April 2013 by a single interviewer. Each participant was provided with 35 tasks to complete on a cell phone with a manual keypad. The tasks were classified according to how it was completed: easily completed, noncritical error, or critical error (where a participant was unable to complete the given task without intervention by the interviewer). The final task was timed using a stop watch. Results: Out of a total of 16 volunteers, 15 completed the testing. The median time to complete the final task was 4 min (range: 2-9). In a cumulative total of 525 tasks, 33 critical errors were noted. Twelve participants had one or more critical errors. The most frequent critical errors were related to typing and spelling mistakes. Twelve out 15 participants were able to complete the final task without any critical errors. Conclusions: Understanding transplant patients' preference in technology use and adapting applications to a variety of technological portals will ensure the most effective use of targeted interventions in patient safety, particularly when applied to preventing drug-drug interactions.
