To pilot a sociotechnical systems-based instrument that assesses the prevalence and nature of self-care barriers among patients presenting to the emergency department (ED) with acute heart failure.
A semi-structured instrument for measuring self-reported self-care barriers was developed and administered by ED clinicians and non-clinician researchers to 31 ED patients diagnosed with acute heart failure. Responses were analyzed using descriptive statistics and qualitative content analysis. Feasibility was assessed by examining participant cooperation rates, instrument completion times, item nonresponse, and data yield.
Of 47 distinct self-care barriers assessed, a median of 15 per patient were indicated as “sometimes” or “often” present. Thirty-four specific barriers were reported by over 25% of patients and nine were reported by over 50%. The sources of barriers included the person, self-care tasks, tools and technologies, and organizational, social, and physical contexts. Seven of the top ten most prevalent barriers were related to patient characteristics and the next three to the organizational context (e.g., life disruptions). A preliminary feasibility assessment found few item nonresponses or comprehension difficulties, good cooperation, high data yield from both closed- and open-ended items, but opportunities to reduce median administration time and variability.
An instrument assessing self-care barriers from multiple system sources can be feasibly implemented in the ED. Further research is required to modify the instrument for widespread use and evaluate its implementation across institutions and cultural contexts. Self-care barriers measurement can be one component of broader inquiry into the distributed health-related “work” activity of patients, caregivers, and clinicians.
Acute heart failure (AHF) is a major and potentially modifiable cause of US healthcare expenditures.1 Patients with AHF typically seek emergency department (ED) care and 80% of these are subsequently admitted to an inpatient setting.2 While approximately 20% are diagnosed with de novo heart failure, most are experiencing an acute exacerbation of chronic heart failure.3 For these patients, AHF related hospitalizations represent the largest proportion of their annual healthcare expenditures.1,4 National estimates of heart failure 30-day readmission rates exceed 20%; heart failure is the top reason for readmission in Medicare patients.5,6
A majority of AHF exacerbations result not only from physiological disease progression, but also due to challenges in self-care, particularly medication and dietary non-adherence.7-9 Self-care non-adherence is believed to occur in part due to a variety of barriers such as knowledge limitations, lack of social support, regimen complexity, and access to or cost of therapy.10-12 If barriers to self-care can be systematically identified and addressed alongside physiological risk, it may be possible to reduce AHF presentations, hospitalizations, and associated costs.8
Identifying and addressing self-care barriers in the ED is desirable because patients may have: 1) insufficient outpatient care support; 2) lack of motivation to address the issues prior to their ED visit; and 3) needs that can be immediately addressed by ED providers, ancillary staff such as social workers and case managers, or through outpatient referral prior to ED discharge.13,14
A recent qualitative study of 28 patients readmitted within 180 days of discharge after an AHF diagnosis found multiple self-reported reasons for readmission including financial difficulties, suboptimal healthcare delivery, and undesirable effects of medications.15 The authors urged further research with patients about their experienced challenges and a “shift from individual blame toward an empowerment and systems approach that considers the big picture”. Accordingly, the present study uses a patient-centered, sociotechnical systems model to assess barriers to heart failure self-care in a sample of patients with AHF presenting to the ED.
Human factors engineering16,17 is a discipline whose sociotechnical systems-based approach has been productively used to understand and improve clinician performance, particularly in the ED.18-21 Recent work suggests this approach can also be valuable for understanding patient and lay caregiver performance of activities such as self-care.22-24 Figure 1 shows a sociotechnical systems model of self-care barriers among AHF patients. Drawing on prior human factors engineering models,16,23-25 it depicts barriers as products of multiple patient, task, technology, and contextual (or environmental) factors.26,27 Several reviews and comprehensive interview-based studies have identified barriers across these system components, but no study in heart failure has used a systems model.10,11,28-31 Furthermore, with few exceptions,14,32 heart failure self-care barriers have not been investigated during an acute exacerbation in the ED.
In parallel to the above work on sociotechnical systems, there has been a growing emphasis on capturing social determinants of health or contextual factors such as poverty and lack of transportation.33 It has been argued that the failure to consider these factors in planning or evaluating care constitutes a “contextual error”34 that results in poorer outcomes.35 Furthermore, in 2014 the Institute of Medicine (IOM) released two reports recommending the use of structured instruments to measure and capture these contextual factors in electronic health records (EHR).36,37
Our study objectives were to: (1) pilot a sociotechnical systems-based instrument to assess the prevalence and nature of barriers among patients presenting to the ED with AHF; and (2) conduct a preliminary feasibility assessment of this instrument in the time-sensitive ED setting.
A semi-structured instrument for measuring self-reported self-care barriers was developed and administered to ED patients diagnosed with AHF. The study was approved by the Vanderbilt University Institutional Review Board (IRB).
This study was performed in the ED at Vanderbilt University Medical Center in Nashville, TN. The ED's census is approximately 70,000 annually, with 700 annual AHF admissions. While most participants were interviewed in the ED, seven were interviewed in a hospital unit.
Adult ED patients were recruited using convenience sampling over an eight-month period between June 2013 and January 2014. A target of 30 participants was established based on resources available for this pilot study. Patients were approached if they were given a primary diagnosis of and treated for AHF by the ED physician. Inclusion criteria were being aged ≥18y, having presented to the ED within 24h, and verification of a primary diagnosis of AHF by EHR or the treating ED physician. Patients were excluded if they were unable or unwilling to perform the interview. Patients’ family members were consented if they showed interest in assisting patients’ responses.
The instrument used self-report to assess the presence and nature of barriers stemming from an array of sociotechnical system factors (Figure 1). All authors, including three ED physicians (two attending, one resident) and two non-clinician researchers (one human factors engineer, one social scientist), reviewed the literature and suggested for the instrument barriers identified in clinical guidelines38-42 or across multiple systematic reviews and individual articles.10,15,29,31,43-55 A few less commonly reported barriers were added because they were identified in the research team's concurrent study of chronic heart failure patients.26,27 One item per barrier was developed, using literacy-appropriate wording based on questionnaires and barrier definitions. Several meetings were held to iterate the instrument. Following internal review and instrument testing with five participants, two items were eliminated due to redundancy and two reworded. The final instrument had 47 structured barrier items. The assessed barriers and precise item wording and order are reported in Appendix A. For each of the barriers, labeled “challenges” in the instrument, participants indicated whether it “often,” “sometimes,” or “never” “makes it harder to take good care of myself.” These verbal qualifiers are commonly used for categorical response scales and have been found to have stable and proportional psychological distance from one another.56,57
The instrument also contained three types of open-ended probes:
Patients were consented and interviewed by either an attending ED physician (ABS, SPC), ED resident (ECE), or a nonclinical researcher (RJH, CCS). The instrument was administered verbally, with the researcher hand-recording answers. Participants wishing to read along were given paper copies of the instrument. Participants were prompted to think about “challenges that you experience taking care of your health,” with challenges defined as “things that make it harder to take good care of yourself.”* This definition was reinforced by the response options (see Appendix A). Participants were first asked the opening probe and encouraged to give complete answers using nondirective language (e.g., “Okay, what else...?”). This was followed by asking the 47 closed-ended questions about specific barriers and follow-up probes to elicit further information about any barrier marked “sometimes” or “often.” Six additional closed-ended questions were asked about self-care facilitators but are not examined here. The interview concluded with the closing probe. Participants were not compensated.
After the interview, a clinician researcher reviewed the patient's medical record and collected demographics, past medical history, diagnoses, and laboratory results.
Data were entered and maintained in a secure REDCap database. Quantitative analyses were carried out in SPSS v.22 (IBM Corp.). To address the first objective, regarding self-care barrier prevalence and nature, we computed (1) the total and mean number of barriers reported as “never,” “sometimes,” and “often” being experienced by patients and (2) the proportion of respondents responding “never,” “sometimes,” and “often” to each barrier item. We also dichotomized responses into “never” and “ever” (“sometimes” and “often”) and computed totals, means, and proportions on the dichotomized scores. We carried out qualitative descriptive analysis58 of volunteered explanations and responses to the open-ended probes to produce a general understanding of each barrier, identify key barriers and barrier-barrier interactions in individual patients, and select illustrative examples. Qualitative description, or conventional content analysis,59 is an approach to describing verbal data that needs no prior structure (or coding framework) nor aims to create new theory. We hypothesized: 1) (H1a) multiple barriers would be reported per patient; 2) (H1b) patients would differ in their key barriers; 3) (H1c) across the sample, patient, task, tool, and context barriers would all be represented; and 4) (H1d) barriers related to individual, task, and social context factors would be especially prominent.
To address the second objective, regarding instrument feasibility in the ED, we calculated participant cooperation rates, instrument completion times, and item nonresponse. We also compared the amount and variety of information yielded using the full instrument versus responses to the opening/closing probes only, the latter resembling the kind of questions asked in standard ED practice (e.g., “Tell me what's going on... Anything else?”). These data and researchers’ anecdotal experiences were combined for preliminary, descriptive feasibility assessment. We hypothesized: 1) (H2a) the instrument would yield value but 2) (H2b) its administration would require streamlining to be integrated into ED practice.
A total of 31 patients participated, described in Table 1. Of these, 30 were admitted to hospital and only one was discharged to home. Fewer than 15% of those approached declined to participate.
A median of 15 out of 47 maximum possible barriers were reported by participants as “ever” being present (mean=16.29, SD=8.8, range 2-38). As shown in Figure 2, barriers were rated as “sometimes” (median=11, M=9.93, SD=4.8) more than “often” (median=5, M=6.35, SD=5.3) and there was a linear relationship between the number of barriers reported as occurring “sometimes” and “often” (r=0.53, p≤.05).
Table 2 reports the prevalence of self-care barriers. Thirty-four of the barriers were reported as ever occurring in >25% of participants and nine barriers in >50%. Among the ten most prevalent barriers, the top seven were related to patient characteristics and the next three to the organizational context. There were several prevalent task-related barriers but tool-related barriers were infrequently reported. Weather and physical obstacles were frequently reported barriers related to the physical context and a food culture incompatible with dietary restrictions was the top barrier related to social context. Table 3 gives paraphrased and verbatim examples of specific barriers described by participants.
Of note, in many cases a participant had multiple self-care barriers (see Figure 2) and these were sometimes related or interacted. Figure 3 shows a barrier profile for one such case, a 52-year old black female with a tenth grade education and a recent incarceration who presented with localized edema after having delayed seeking treatment for about a month due to being uninsured. This individual describes multiple barriers across the different sociotechnical system categories and plotting these offers some insight into the distribution of barriers—in this case, a relatively even one, except for the absence of tool and technology barriers. Further, through the patient's responses to open-ended follow-up probes it is clear that some of the barriers interact:
Notably, patients’ barrier profiles sometimes resembled the one in Figure 3 but at other times showed a different distribution of barriers. For example, there were two patients with significant social context barriers but no reported physical context barriers. Two others had relatively few organizational context barriers but reported having person-related barriers and a lack of tools.
With respect to feasibility, instrument administration lasted a median of 30 minutes and ranged from 20 to 90 minutes. Longer encounters were ones during which the participant had many barriers to probe or complicated explanations of their barriers; there was a modest correlation of r=0.40 between number of barriers reported and interview duration (though not taking into account interruptions). Durations were also longer with patients who had trouble concentrating. Reproduced below are abbreviated field notes following a 50-minute interview:
Patient had difficulties responding to the questions ... she was very slow and needed time to think. After 40 minutes, became restless, turning in bed as if difficult to get comfortable. Did not want to provide additional comments at the end of the interview and while she remained friendly clearly wanted to be left alone. Patient's chart shows diagnosis of bipolar disorder.
In 45% of cases, an informal caregiver was present during all or part of the encounter. Consenting caregivers sometimes helped to answer questions and fill in details, especially when the patient was less able (from fieldnotes: patient got very tired towards the end of the interview and her fiancé started to chime in more frequently).
There were very few item nonresponses, with an average of 0.39 items skipped or refused per participant (range 0-2 out of 45). Only one item (fitting self-care into the daily schedule) had more than one nonresponse across the 31 participants. Furthermore, most items yielded at least some responses of “sometimes” and “often.” Only one (lack of “workspace” for self-care tasks) yielded only “never” responses and four others (caregiver unavailability, resources for keeping appointments, low quality healthcare, tool overdependence) had >85% responses of “never.” Only four (13%) participants had visible trouble comprehending item wording. Although the researcher always provided a written copy of the instrument, this was not always effective (from fieldnotes: reading questions with patient was a little difficult because he could not look at the sheet and read with me because of literacy issues). Further, not all participants provided thorough open-ended responses when probed to elaborate about reported barriers; in several cases this appeared to be related to the patient's desire to complete the instrument quickly.
Researchers experienced good cooperation, with <15% of those approached declining to participate. Any initial reluctance in answering questions appeared to dissipate with time, as participants provided more details describing specific barriers as the interview progressed.
Considerably more information was obtained by asking specific questions, beyond the yield from the opening probe (“What are some of the challenges that you experience...?”). In fact, less than half (42%) could provide a coherent open-ended answer about self-care barriers, despite all participants reporting a number of barriers when asked specific structured items. For example, one participant did not reply to the opening probe but then indicated “sometimes” or “often” experiencing 35 (74%) of the specific barriers; he spent 45 minutes describing in depth dealing with HIV/AIDS, having his driver's license suspended, not knowing when his medications are changed or what he should be eating, being scared to take medications, not having anyone to help him, and having to stay in a homeless shelter. This and other examples of patients “opening up” illustrate the usefulness of asking specific structured probes. In contrast to the limited information obtained using the opening probe, the follow-up probes usually yielded additional information about the specific nature of the barrier that could not be learned from “often,” “sometimes,” or “never” responses alone (see Table 3). For example, a patient probed to elaborate on why they indicated “often” experiencing a lack of food-related resources explained that it is “more expensive to get the right foods.” Occasional probes following “never” responses were also sometimes useful. For instance, one patient reported “never” having problems with knowledge about dietary self-care recommendations but went on to explain that the “real issue”: between diabetic dietary restrictions, a lack of energy, and suppressed appetite, fast food and packaged products were an easy choice to make over preparing healthy food herself.
Thirteen (42%) patients provided information in response to the closing probe. Responses usually reemphasized a barrier that was already described, summarized their thoughts about self-care, or in a few cases provided additional detail about self-care barriers. For the 58% who provided no response to the closing probe, it was not clear whether this was due to the exhaustive nature of the specific barrier items or participant fatigue. Examining the barriers reported in opening and closing probes only, a median of 2.5 barriers were mentioned (range 1-13), and these were mostly “person” barriers (e.g., comorbidities, functional limitations, and knowledge). The second most commonly reported unprompted barrier type was organizational issues such as financial constraints, insurance problems, and inadequate living arrangements.
Researchers reported difficulties administering the instrument due to interruptions for clinical treatment, which also produced longer instrument administration durations, and the confined and noisy environment of the ED room.
Our instrument combined closed- and open-ended questions to take advantage of strengths and mitigate limitations of existing quantitative survey instruments and less-structured qualitative interview instruments, particularly with respect to deployment in a time-sensitive ED setting (Table 4).
We note that all but one participant was admitted to the hospital, but this was consistent with the ED's typical rate of 90% admission for AHF and with a national 5-year rate of over 80%.2 Because of our relatively small sample size and use of a single ED, further research will be needed to verify our findings and further test and develop the feasibility of the instrument. In light of evidence that self-care behaviors and perceptions may be culture-specific,60-63 future work should use our instrument for a cross-cultural comparison. Moreover, it is possible that patients were unable or unwilling to accurately report their self-care barriers. Some barriers such as food culture or tool overdependence may fall outside of an individual's awareness. Others may be overly sensitive or difficult to articulate, especially in front of individuals affiliated with one's healthcare delivery system. Some of this might be alleviated by using electronic, self-administered instruments. Other methods could also be used to supplement our self-care barriers instrument. Possibilities include independent home or community assessments, mining of the EHR for information on barriers,64 or the use of geospatial information to determine a patient's or group of patients’ self-care barriers.65 For example, automated geospatial analysis of food, exercise, and transportation resources near a patient's home and work could provide information without the need for patient self-report.
Additional planned analyses will address associations between reported barriers and variables such as presence of a family member, comorbidity, number of prior ED visits, prior medical history, and demographics. It also remains to be seen which barriers are correlated with others (e.g., cognitive impairment and knowledge, transportation problems and lack of caregiver). Furthermore, future tests of the instrument in practice would benefit from more formal assessments of feasibility, including costs data.
In this study of 31 patients presenting to the ED with AHF, we piloted an instrument with both structured and open-ended items measuring the prevalence and nature of barriers to self-care. Of the 47 distinct barriers assessed, many were indicated as sometimes or often present by participants, all patients reported experiencing multiple barriers, and patients had various barrier profiles. The sources of barriers included the person, self-care tasks, tools and technologies, and organizational, social, and physical contexts. This was consistent with patient-reported barriers from Retrum et al.'s15 recent interview study which suggested that symptom severity, disease progression, mood, transportation problems, lack of food resources, cost of medications and financial stress, and inadequate access to and quality of healthcare services were reasons for heart failure patient readmission. Our study identified those and other barriers, while also providing prevalence information. It was the first study in the ED to describe the complexity of patients’ self-care barriers and an important illustration of a patient-centered, sociotechnical systems-based approach to research on AHF patients in the ED.
Patients discharged from the ED or hospital following an AHF diagnosis may be clinically stable but otherwise underprepared to perform self-care recommendations such as medication self-management, diet, and symptom monitoring.8 Recognizing this, Moser et al.66 stated:
The number of psychological, social, and behavioral risk factors that challenge many patients adds substantially to the risk burden conferred by physiological factors. Depression, anxiety, poor quality of life, functional impairment, poor symptom status, suboptimal living situation, comorbidities, and poor adherence are common among discharged HF patients. Healthcare providers must develop more aggressive strategies to assess these risk factors so that they can be appropriately managed after discharge.
However, clinicians rarely assess or document the full range of risk factors or self-care barriers. One study of such barriers noted that “few charts showed evidence that the physician of record inquired in depth into patients’ social support systems and postdischarge environment.”15 This underassessment that occurs in the ED is likely multifactorial. It may be impacted by the perceived time required to do this, the lack of expertise in probing patients about their barriers, and the means to address barriers that may arise during the assessment. Assessing self-care barriers in a setting such as the ED is achievable using an instrument that captures a range of relevant barriers, elicits enough information about each barrier to be able to address it appropriately, and can be completed without undue burden. We believe the first step in addressing barriers is to develop a focused, valid, and feasible measurement instrument for self-care barriers in the ED. This will facilitate not only a discussion about patient barriers, but will also inform providers about barriers that may be intervened upon during an ED visit. Addressing these barriers is a critical unmet need and is crucial to enable safe ED discharge of patients with AHF. While most of the patients in this study were not discharged from the ED or managed in an ED-based observation unit, based on prior estimates,8,67 up to 30% could have been and knowing their barriers, or lack thereof, may have informed the decision to do so and the kinds of resources that might need to be provided when discharged from the ED. Resources to address barriers could include changes to medications, access to medications and providers, education, and referral to social work or community safety net resources. It is important to better develop the resources and solutions, such as programs for free or reduced-price medications, transportation pools, or literacy-appropriate brochures, so that they can be matched to identified barriers.
Recent reviews of the literature demonstrate that self-care barriers are related not only to important biomedical and personal characteristics such as symptom severity, medication knowledge, and health literacy,12,68 but to factors from the broader sociotechnical system, which includes the person, their environment and healthcare system, and more.10,11,30,54 However, quantitative survey studies have typically measured only a few variables, particular quantifiable patient factors such as age, health status, illness beliefs.11,32 Prior qualitative studies using in-depth interviews have successfully identified self-care barriers from the broader system,28,69 but while these have been instructive, they have lacked systems models, consistent reporting of barrier prevalence, and barrier assessments instruments that can be feasibly implemented in the ED. In this study, measuring a wide assortment of barriers across the whole sociotechnical system, person barriers were common but so were organizational context and task barriers. Moreover, for some individuals, profound barriers from the social and physical context were found. Only tool-related barriers were infrequently reported, though only two items were used to measure these. Notably, the structured barrier items and follow-up probes yielded a larger number and bigger variety of reported barriers, compared to opening and closing probes resembling the kinds of questions asked in normal clinical practice.
Importantly, a wide array of barriers could be feasibly measured in the ED by clinicians and non-clinicians. Instrument administration time was somewhat longer and more variable than desirable, but we believe that with modification the instrument can be administered in ≤30 minutes. Items may need to be eliminated or combined prior to widespread implementation. Item deletion can be guided by deploying the instrument in a sample large enough for factor analysis and reliable identification of low-frequency barriers. We believe that a variety of research or clinical staff could have administered the instrument and this should be explored in subsequent multi-center investigations. ED and inpatient settings are feasible environments for extended data collection because the instrument can be administered during waiting times. In contrast, recent work has identified numerous specific but addressable challenges for collecting self-care barriers and other data in home and community settings.70
An emerging finding is that heart failure self-care and other health-related activities are carried out in the context of a multifaceted and highly distributed self-care system.22,27,71 From a distributed cognition perspective,72,73 heart failure self-care tasks, knowledge, and expertise are distributed across people (e.g., patient, informal caregivers, physicians, nurses, community pharmacists), artifacts (e.g., weight logs, ED white board), time (e.g., days, nights, before/after meals), and space (e.g., park, kitchen, the ED, doctor's office, retail pharmacy). This implies that self-care goals are rarely achieved by a single person (e.g., the patient) or single entity (e.g., the ED) but come about through the shared awareness of plans and goals, a joint understanding of a situation, the collaborative and coordinated use of technology and other resources (e.g., EHR), as well as the proper arrangement of physical spaces in which self-care activities take place.74,75
It is also important to note that heart failure management is a dynamic process that involves recognition and adapting to unexpected variability and perturbations, called “resilience.”76 In a resilient system, adequate decision-space, flexibility, and opportunity for collaboration must be built into its design so that local actors (e.g., patients, family, healthcare professionals) are able to manage trade-offs or derive sensible workarounds to respond to expected and unexpected goal-constraints.77,78 Self-care barriers are one of the constraints that these individuals must collaboratively and successfully manage to achieve resilience.
In conclusion, we believe not measuring and acting on self-care barriers represents a significant lost opportunity to improve care as well as decrease future ED visits and hospitalizations.8 While doing so may require an up-front investment in resources, it will have significant downstream impact and cost savings. Merely decreasing readmissions by 5% would conserve significant healthcare resources.8,79 For this and other reasons, we and others urge deeper inquiry into the contextual factors that shape the distributed and resilient health-related “work” of patients.24,80
