Abstract
Background Children with medical complexity (CMC) are uniquely vulnerable to medication errors and preventable adverse drug events because of their extreme polypharmacy, medical fragility, and reliance on complicated medication schedules and routes managed by undersupported family caregivers. There is an opportunity to improve CMC outcomes by designing health information technologies that support medication administration accuracy, timeliness, and communication within CMC caregiving networks.
Objectives The present study engaged family caregivers, secondary caregivers, and clinicians who work with CMC in a codesign process to identify: (1) medication safety challenges experienced by CMC caregivers and (2) design requirements for a mobile health application to improve medication safety for CMC in the home.
Methods Study staff recruited family caregivers, secondary caregivers, and clinicians from a children's hospital-based pediatric complex care program to participate in virtual codesign sessions. During sessions, the facilitator-guided codesigners in generating and converging upon medication safety challenges and design requirements. Between sessions, the research team reviewed notes from the session to identify design specifications and modify the prototype. After design sessions concluded, each session recording was reviewed to confirm that all designer comments had been captured.
Results A total of N = 16 codesigners participated. Analyses yielded 11 challenges to medication safety and 11 corresponding design requirements that fit into three broader challenges: giving the right medication at the right time; communicating with others about medications; and accommodating complex medical routines. Supporting quotations from codesigners and prototype features associated with each design requirement are presented.
Conclusion This study generated design requirements for a tool that may improve medication safety by creating distributed situation awareness within the caregiving network. The next steps are to pilot test tools that integrate these design requirements for usability and feasibility, and to conduct a randomized control trial to determine if use of these tools reduces medication errors.

Background and Significance
Medication Errors among Children with Medical Complexity
Children with medical complexity (CMC) are uniquely vulnerable to medication errors and preventable adverse drug events because of their extreme polypharmacy, medical fragility, and reliance on complicated medication schedules and routes (e.g., enteral tubes) managed by undersupported family caregivers.[1] [2] [3] Routine CMC care typically involves high-risk medications having severe consequences if doses are missed and toxicity if doses are in excess. In one study focused on in-home medication administration for pediatric patients, over half of medication errors identified during in-home observation were classified as having potential to harm the child; one-in-seven resulted in injury.[4] However, even when administration errors do not lead to catastrophic adverse drug events, incorrect administration can lead to patient harms, such as undertreatment or continuation of unwanted symptoms.[4]
#
Challenges to Medication Safety among Children with Medical Complexity Caregivers
The systems' current reliance on family caregivers to manage complex medication regimens for their CMC creates a system prone to suboptimal outcomes. Challenges faced by caregivers who are managing complex medication regimens are well documented.[5] [6] [7] Parents and nonmedical caregivers are expected to manage and administer medications in the home setting without formal training or CMC-specific tools to support medication administration accuracy, which may affect accuracy and safety.[8] [9] [10] [11] [12] Among the most complex pediatric patients, some caregivers must administer a median of 50 doses per day, comprised of both scheduled and as needed medications.[13] Home medication errors have been documented with underlying reasons including communication problems between CMC caregivers and providers, misunderstandings about how to prepare and administer medications, and lack of medication-related tools (e.g., alarms, reminders) to help support caregivers who administer medications.[4] [14] [15]
#
Medication Safety within a Caregiving Network
Caregivers of CMC are also uniquely challenged to distribute complex medication management across a network of caregivers. This network includes “secondary caregivers” (e.g., relatives, school aides, home health nurses), who are depended upon to deliver timely and accurate life-sustaining medications for CMC on a daily basis, despite having comparatively less familiarity with a given child's care plan.[16] [17] [18] Currently, families are expected to develop and implement their own strategies for ensuring safe, standardized medication management across the network of secondary caregivers, but they struggle to do this.[4]
There is an opportunity to design tools that meet two distinct but related unmet needs: first, to support the accuracy and timeliness with which CMC caregivers administer medications; and second, to support the “networked” nature of medication management, acknowledging that it occurs across multiple caregivers whose communication is key to success. Health information technologies (HIT), or electronic tools that professionals and patients alike can use to store and share health information, are shown to be promising tools to facilitate adherence and communication in other clinical settings.[19] [20] Prior work focused on CMC enteral tube care at home indicates that caregivers of CMC require HIT to improve organization and communication among the caregiving network.[21] This finding highlights the need for HIT that support CMC networks' medication management, including access to, awareness of, and exchange of medication information.[22]

Objectives
The present study engaged family caregivers, secondary caregivers, and clinicians who work with CMC in a codesign process to identify: (1) medication safety challenges experienced by CMC caregivers and (2) design requirements for a mobile health application (mhealth app) to improve medication safety for CMC in the home.
#
Methods
Study Design
We conducted an established five-stage, multiperspective codesign process, which engages end user representatives as active members of the design team.[23] [24] [25] The five stages of the design process include: problem identification, in which the challenge to be addressed is defined and described by codesigners; solution generation, in which codesigners creatively discuss possible ways of addressing the problem; convergence, in which codesigners reach agreement on the most appropriate design requirements to address the problem; prototyping, in which the research and design teams work together to translate the requirements into a rough prototype; and evaluation, in which designers provide feedback on the strengths and weaknesses of the initial prototype.[26] The activities associated with each stage of this process are described in [Table 1]. Because codesign involves end users as designers, the resulting tools are more likely to be usable, useful, relevant, acceptable, and adaptable to end users' current routines.[23] [27] Further, because the data gained from codesign sessions are qualitative, the research team and software developers gain a richer understanding of end users' real worlds in which tools are used, why previous tools may have failed end users, and ultimately how to promote sustained use.[28] [29]
We defined medication safety as ensuring that the CMC received the right medications, at the right dose, and at the right time, no matter who gives the medication or where the CMC is. All codesign sessions were conducted between August and December of 2022 over teleconferencing software. The University of Wisconsin–Madison and Indiana University–Bloomington Institutional Review Boards reviewed and approved all stages of this project.
#
Participants and Recruitment
To ensure a heterogeneous and clinically informed perspective on medication safety in daily care, participants included family caregivers, secondary caregivers, and clinicians caring for CMC.[29] Eligibility criteria included speaking English, having internet access, and willingness to attend the majority of the respective group's codesign sessions (i.e., all family caregivers together, secondary caregivers together, and clinicians together). Family and secondary caregivers were offered $25 per session.
A convenience sample of family caregivers and clinicians were recruited from a children's hospital-based pediatric complex care program (PCCP). Clinicians included nurses, doctors, and pharmacists who work with CMC. Study staff worked with family caregivers and clinicians to compile a list of potential secondary caregiver participants.
Study staff sent potential family and secondary caregivers opt-out letters, describing the study and what their participation would involve, and then followed up by phone to further explain the study and assess their eligibility and interest. Clinicians were sent emails describing the study and what their participation would involve. All interested and eligible participants were asked about their availability for the codesign sessions, dates, and times for the sessions were chosen, and meeting invites were sent to all participants. In all cases, consent was obtained before participation.
#
Codesign Sessions
Presession Preparation
As preparation for the first codesign session, family and secondary caregivers responded to a journal prompt. The journal prompt asked them about things that can go wrong with the CMC's medication administration throughout the day, and what they have done to keep things from going wrong.
#
Codesign Session Process
Codesign sessions lasted 1 hour and were audio recorded. Each session was attended by at least four members of the research team: a facilitator (N.E.W.), a research coordinator (H.K.), a note-taker (A.J.), and a software developer and/or a user experience designer (S.O. or M.W.). To promote participation and equanimity, the facilitator used open-ended questions, probed quieter codesigners to speak, and encouraged the use of the teleconferencing platform's chat function. The web-based tool Miro, which is a virtual whiteboard, was used to document and organize design requirements in real time.[30] The software Figma was used to adapt the prototype during and between design sessions.[31]
The agenda of each codesign session was designed to generate discussion among participants around challenges to medication safety and design requirements for a medication safety app. In the first session, the facilitator laid the “ground rules” for participation. Ground rules included suggestions that participants keep their cameras on, for example, and the request that we would like to hear from everyone. When necessary, the facilitator invited (but did not require) quieter participants to share. Each design session focused on one design stage in sequence from problem identification, solution generation, convergence, prototyping, and evaluating the initial prototype. Content for the first session (problem identification) was informed by presession journal prompts, and content for subsequent sessions built iteratively upon challenges identified in the first session. [Table 1] depicts the design process, including design activities, design tools, and facilitator prompts.
#
Survey
After design session one, all participants completed a demographic survey, which included age, gender, race, ethnicity, and the highest level of education completed. In addition, family caregivers reported their relationship to the CMC, marital status, whether a language other than English is spoken at home, 2021 household income, and geographic area (urban, suburban, or rural). Family caregivers also reported the number of caregivers in CMC's network with whom they interact at least monthly; medicines taken daily by the CMC; and hospital days in the last 12 months.
#
#
Data Analysis
The research team consisted of clinicians, a human factors engineer, a user-centered design expert, a software developer, research coordinators in the fields of pediatrics and human factors engineering, a pharmacist, and a CMC family representative. Data analysis occurred within and between codesign sessions. Within sessions, the facilitator-guided codesigners in generating, grouping, and converging upon medication safety challenges and design requirements. Between sessions, the research team discussed codesigners' design requirements and assigned them a priority level, focusing on factors such as urgency; technological feasibility, from budgetary and software development perspectives; and relative emphasis from codesigners. The prototype was then modified in Figma, prioritizing higher priority design requirements.[31] At each subsequent design session, the prototype was brought to codesigners for feedback on how to better meet their medication management needs. After all design sessions had completed, a research team member who was present for the design sessions (A.J.) listened to each session recording to confirm that all designer comments had been captured and extracted all challenges and design requirements to a spreadsheet. Presession journals were also extracted to this spreadsheet. A second and third team member (N.E.W., H.K.) who were present for each design session reviewed medication safety challenges and design requirements for completeness. Last, these results were brought back to the full research team for refinement and discussion.

Medication Safety Challenges and Design Requirements
Analyses yielded three overarching challenges to medication safety: giving the right medication at the right time; communicating with others in the care network about medications; and accommodating complex medical routines. Medication safety challenges, corresponding design requirements, supporting quotations from codesigners and prototype features are presented in [Tables 3] [4] [5].

Challenge 1: Giving the Right Medication at the Right Time
An overarching risk to medication safety involved administering the right medication at the right time. This included administering the correct dosage via the correct route; administering the dosage at the right time; integrating prescribed or as-needed changes to medications; and completing medication refills on time.
To assist with giving the right medication at the right time, family caregivers requested that the app store information about each prescribed medication (including its color and shape) and its respective dose. They also sought the ability to color-code the medications (e.g., using a designated color for as-needed medications) or associate certain icons with certain types of medications (e.g., a snowflake for refrigerated medications), to further assist them in quickly differentiating between medications. Clinicians added that the app should warn the user if they enter an unlikely dosage or unsafe route when adding a new medication.
Family caregivers wanted the app to accommodate changes to the medication routine, including skipping a medication, adding a new daily medication, or adding PRN (pro re nata, i.e., as-needed) medications. Family caregivers asked that information about a child's PRN medications and their respective doses be stored in the app, to be “dragged” to the daily schedule when needed. Clinicians requested that the app suggest PRN routines to users when indicated by the CMC's symptoms; for example, the app could suggest administering propranolol if the CMC's blood pressure was high.
Family caregivers and clinicians alike emphasized the challenge of ordering and receiving medication refills on time. Family caregivers thus wanted the app to automatically track how many doses were left and to remind them when a medication refill was due. Clinicians added that refill reminders should be sent not only for medications, but also for medical supplies.
#
Challenge 2: Communicating about Medications
Family caregivers described the challenge of communicating with others in the caregiving network (within and outside of the home) about medications, both synchronously and asynchronously. In the first design session, one family caregiver illustrated the challenge of communicating synchronously within the home: “We have a lot of 'did I give that to him already? Did you give that to him?'” Family caregivers wanted the app to indicate when a medication had already been administered, when a dose had been missed, or when a secondary caregiver elected to skip a dose of a medication.
The communication challenge continued at school. One secondary caregiver, who was a school nurse, shared that receiving medication information from parents is not enough. “State statutes require written instruction from a physician,” she reported. The secondary caregiver agreed that a picture of the written order would alleviate the need for parents to print the order out or for the school nurse to contact the doctor's office.
Caregivers imagined that a notes feature could facilitate asynchronous communication within the caregiving network. One family caregiver imagined that, in preparation for visiting the neurologist, she might assemble all her notes about seizure activity since their last visit. Another caregiver wanted the ability to “tag” another caregiver in a note and to see a visual cue when that caregiver had “seen”' or “read” the note.
#
Challenge 3: Accommodating Complex Medical Routines
According to family caregivers, medication administration occurred in the context of other types of medical routines and risks. To that end, family caregivers requested that the app warn users about allergies; enable the users to track a variety of health-related events; and enable users to complete nonmedication types of routines.
One family caregiver highlighted the importance of making her child's allergies salient for his entire network. “My son has a kidney issue. He should not use ibuprofen…. I don't want anybody to even think ibuprofen if he has a fever.” Within the app, family caregivers wanted allergy information to be “unmissable.” This also applied to food and drink that the CMC should not receive.
Family caregivers noted that there are many things that they track on their child's behalf, and often multiple times per day, such as oxygen levels, blood pressure, and seizure activity. One home health nurse felt the same pressure to keep track of everything: “[Parents will] ask me about specific symptoms or just a scenario about how [the CMC is] doing.” With a health tracking feature, she said, “they would have that in the palm of their hand.”
Caregivers acknowledged that medications are but one type of routine in a CMC's day. Family caregivers wanted to be able to add both medical tasks (e.g., using a ventilator, shaker vest, or cough-assist device) and general health-related tasks (e.g., feeding the child, giving the child a bath). Family caregivers wanted the ability to drag these nonmedication tasks to the daily calendar “as soon as I think of it” so that neither family nor secondary caregivers would forget to complete them.

Discussion
In this study, we engaged family caregivers, secondary caregivers, and clinicians caring for CMC in a codesign process to identify: (1) challenges to medication safety experienced by the caregiving network and (2) design requirements for an mhealth application that could improve medication safety in the home and community. Design sessions yielded 11 challenges to medication safety and 11 associated design requirements, which fit into three broader challenges: giving the right medication at the right time; communicating with others in the caregiving network about medications; and accommodating complex medical routines. Those creating HIT can use these findings to develop technologies to improve medication safety for CMC and their caregivers.
The challenges to medication safety identified in this study align with and build upon previous research. Like Walsh et al, we found that caregiving networks struggle with administering correct dosing (e.g., missing doses, double dosing, or administering the wrong dose) and with communicating between caregivers (e.g., communicating when a dose has already been administered or when the prescribed dose has changed).[4] Our study expands upon these findings, adding that refilling prescriptions for medications or medical equipment is also a key challenge. Our findings also add to existing literature on secondary caregivers, which has demonstrated the challenge of communicating with family caregivers, other secondary caregivers working different shifts, and with CMC's clinicians.[32] Our findings suggest that secondary caregivers want HIT to support verifying clinician orders, documenting care, and communicating with caregiving network members (e.g., health-related event tracking and tagging each other in notes).
Overall, our findings highlight the challenge of building and maintaining awareness of a CMC's medications across all caregivers, all contexts, and all conditions, which is critical to safe medication management. This degree of awareness could understandably overwhelm any one caregiver. Thus, our results point to the need for HIT that supports distributed situation awareness (DSA).[33] Within a caregiving network, situation awareness can and should be shared between human agents (i.e., caregiving network members) and nonhuman agents (e.g., notepads, medication labels, smartphones). Further, each agent varies in its perspective and knowledge of the system. In the context of the present study, a school nurse may know whether the CMC received their medication at school; a clinician may know what medication changes are necessary to improve health; and a medication label may “know” the correct medication dose. Although the current system requires family caregivers to know all of this information, the reality imparted by DSA is that, within a complex system, no single agent ought to be responsible for all information at all times. The design requirements identified in this study support medication safety by supporting DSA—that is, by storing all medication information and distributing it to the relevant caregivers, in the appropriate contexts, and when certain conditions apply.
All types of caregivers in the present study identified communication among caregiving network members as a key challenge to medication safety. Indeed, previous research demonstrates that communication failures are commonly associated with medication errors in the home.[4] [15] Family caregivers in this study wondered if medications had already been administered and when medications were due for a refill. Secondary caregivers wondered what happened during the previous shift, and how to communicate what happened during their own. Family and secondary caregivers alike sought an easier way to synthesize and communicate clinical data with clinicians. HIT that centralizes, organizes, and facilitates communication within the caregiving network has great potential to address communication-related medication errors for CMC in the home and community.
Limitations
This study had limitations. First, all family caregivers identified as Caucasian, identified as female, lived in the same state, and lived above the poverty level in that state. It is possible that a more socially and economically diverse sample of caregivers, as well as a more clinically diverse sample of CMC, would identify different risks to medication safety and thus different design requirements. Thus, intentionally enrolling diverse participants is a vital next step.[34] Second, all participants' CMC were enrolled in a complex care program. Medically complex children without access to a PCCP may face different risks. Third, the design requirements identified in this study have yet to be tested for usability, feasibility, and effectiveness at reducing medication errors. Future research on the prototype described in this study will both qualitatively and quantitatively describe the results of testing.[35] It is likely that end users will identify new or different needs upon extended use of the prototype. Last, achieving equal participation among group members in codesign is challenging, and in the present study we did not measure nor document the equality of participation. It is vital that future codesign studies measure and take steps to promote equity and inclusivity in group research settings.[36]

Conclusion
This study identified key challenges to CMC medication safety in the home and generated design requirements for a tool to improve medication safety. The next steps to improving CMC medication safety are to pilot test the tool for usability and feasibility, and then to conduct a randomized control trial to determine if use of the tool reduces medication errors and improves CMC clinical outcomes.
#
Clinical Relevance Statement
Medication administration within the caregiving networks of CMC is prone to sometimes dangerous errors. In our study, caregivers and clinicians identified design requirements of a mhealth application that could improve medication safety at home by empowering caregivers to give the right medication at the right time, facilitating communication between caregiving network members, and accommodating the complex medical routines of CMC.
