Utilization, Determinants, and Prospects of Electronic Medical Records in Ethiopia.

BACKGROUND: A lot of effort is being done in the electronic medical record (EMR) system. However, it has not been implemented and used at the expected scale for maximal effectiveness. There is limited evidence on the factors affecting the utilization of EMR in this particular context, which are critical for targeted strategies. OBJECTIVE: To assess the magnitude and factors affecting the utilization of EMR among health professionals in eastern Ethiopia. METHODS: An institutional-based cross-sectional study was conducted among randomly selected 412 health professionals from Harari and Dire Dawa, eastern Ethiopia, using a pretested self-administered questionnaire. The tool was developed from previous literature, and a pilot survey was done before the actual study. Bivariable and multivariable binary logistic regression were done to assess the relationship between an independent variable with EMR use. Crude and an adjusted odds ratio with a 95% confidence interval were reported. A P value of less than 0.05 was used to declare a statistically significant association. RESULTS: A total of 412 health professionals with a mean age of 29 years (±6.4 years) were included. A total of 229 (55.6%) and 300 (72.8%) of them had good knowledge and attitude towards the EMR, while 279 (67.7%) used the service (54% used it on a daily basis). About 272 (66%) of the respondents reported that they prefer EMRs to paper-based systems. Health professionals with more than five years of experience had two times higher odds of using the service (AOR = 2.22; 95% CI; 1.12-4.42) than early-career workers. Health professionals trained in EMR would use the service more (AOR = 5.88; 95% CI; 2.93-11.88) compared to those who did not take the training. In addition, having good knowledge (AOR = 1.52; 95% CI; 0.92-1.5) and a good attitude towards the EMR system (AOR = 2.4; 95% CI; 1.35-4.31) showed to use EMR as compared to counterparts. CONCLUSIONS: The utilization of EMR was found to be optimal. Age, work experience, knowledge, attitude, and training of professionals were positively associated with the use of the service in their facility.

Quantifying Patient Portal Use: Systematic Review of Utilization Metrics.

BACKGROUND: Use of patient portals has been associated with positive outcomes in patient engagement and satisfaction. Portal studies have also connected portal use, as well as the nature of users' interactions with portals, and the contents of their generated data to meaningful cost and quality outcomes. Incentive programs in the United States have encouraged uptake of health information technology, including patient portals, by setting standards for meaningful use of such technology. However, despite widespread interest in patient portal use and adoption, studies on patient portals differ in actual metrics used to operationalize and track utilization, leading to unsystematic and incommensurable characterizations of use. No known review has systematically assessed the measurements used to investigate patient portal utilization. OBJECTIVE: The objective of this study was to apply systematic review criteria to identify and compare methods for quantifying and reporting patient portal use. METHODS: Original studies with quantifiable metrics of portal use published in English between 2014 and the search date of October 17, 2018, were obtained from PubMed using the Medical Subject Heading term "Patient Portals" and related keyword searches. The first search round included full text review of all results to confirm a priori data charting elements of interest and suggest additional categories inductively; this round was supplemented by the retrieval of works cited in systematic reviews (based on title screening of all citations). An additional search round included broader keywords identified during the full-text review of the first round. Second round results were screened at abstract level for inclusion and confirmed by at least two raters. Included studies were analyzed for metrics related to basic use/adoption, frequency of use, duration metrics, intensity of use, and stratification of users into "super user" or high utilizers. Additional categories related to provider (including care team/administrative) use of the portal were identified inductively. Additional analyses included metrics aligned with meaningful use stage 2 (MU-2) categories employed by the US Centers for Medicare and Medicaid Services and the association between the number of portal metrics examined and the number of citations and the journal impact factor. RESULTS: Of 315 distinct search results, 87 met the inclusion criteria. Of the a priori metrics, plus provider use, most studies included either three (26 studies, 30%) or four (23 studies, 26%) metrics. Nine studies (10%) only reported the patient use/adoption metric and only one study (1%) reported all six metrics. Of the US-based studies (n=76), 18 (24%) were explicitly motivated by MU-2 compliance; 40 studies (53%) at least mentioned these incentives, but only 6 studies (8%) presented metrics from which compliance rates could be inferred. Finally, the number of metrics examined was not associated with either the number of citations or the publishing journal's impact factor. CONCLUSIONS: Portal utilization measures in the research literature can fall below established standards for "meaningful" or they can substantively exceed those standards in the type and number of utilization properties measured. Understanding how patient portal use has been defined and operationalized may encourage more consistent, well-defined, and perhaps more meaningful standards for utilization, informing future portal development.

Effect of COVID-19 on computed tomography usage and critical test results in the emergency department: an observational study.

BACKGROUND: The effect of the coronavirus disease 2019 (COVID-19) pandemic on new or unexpected radiologic findings in the emergency department (ED) is unclear. The aim of this study was to determine the effect of the COVID-19 pandemic on the number of computed tomography (CT) critical test results in the ED. METHODS: We performed a retrospective observational study of ED CT usage at 4 Ontario hospitals (1 urban academic, 1 northern academic, 1 urban community and 1 rural community) over 1 month during the COVID-19 pandemic (April 2020) and over the same month 1 year earlier (April 2019; before the pandemic). The CT findings from 1 of the 4 hospitals, Hamilton Health Sciences, were reviewed to determine the number of critical test results by body region. Total CT numbers were compared using Poisson regression and CT yields were compared using the χ2 test. RESULTS: The median number of ED CT examinations per day was markedly lower during the COVID-19 pandemic than before the pandemic (82 v. 133, p < 0.01), with variation across hospitals (p = 0.001). On review of 1717 CT reports from Hamilton Health Sciences, fewer critical test results were demonstrated on CT pulmonary angiograms (43 v. 88, p < 0.001) and CT examinations of the head (82 v. 112, p < 0.03) during the pandemic than before the pandemic; however, the yield of these examinations did not change. Although the absolute number of all CT examinations with critical test results decreased, the number of CT examinations without critical results decreased more, resulting in a higher yield of CT for critical test results during the pandemic (46% [322/696] v. 37% [379/1021], p < 0.01). INTERPRETATION: Emergency department CT volumes markedly decreased during the COVID-19 pandemic, predominantly because there were fewer examinations with new or unexpected findings. This suggests that COVID-19 public information campaigns influenced the behaviours of patients presenting to the ED.

Investigating inappropriate admissions and hospitalizations in Yasuj educational hospitals based on appropriateness evaluation protocol (AEP): A case study in the internal and surgical wards.

BACKGROUND: Examining the conditions for hospital admission and its appropriateness, and continuous investigation of hospital services are important issues that can improve resource productivity, service quality, and hospital efficacy. So, the present study was conducted to determine the appropriateness of the services provided in Yasuj educational hospitals. METHODS: This descriptive-analytical study was carried out on 204 hospitalized patients who were selected through multistage quota sampling in 2016. The appropriateness evaluation protocol (AEP) was used to collect the data. Analytical tests such as paired t-test, chi-square test, and Fisher's exact test were used to determine the relationship between appropriate and inappropriate admission and hospitalization and demographic characteristics. The data were analyzed using the SPSS18 statistical software. RESULTS: A total of 980 days of stay were evaluated, and according to the AEP, 35 days of hospitalization were considered inappropriate (3.57%). The mean hospitalization duration was 6/16 ± 5/53 days. The results showed that inappropriate admission and hospitalization rates were respectively 0.6% and 13.8%. CONCLUSION: Unnecessary admissions and hospitalizations can be considered as one of the challenges of the health system. Reducing unnecessary hospitalization will increase hospital productivity, reduce the waiting list and hospitalization costs, and also reduce the risk of exposure to hospital infections. In order to prevent inappropriate admissions and unnecessary hospitalizations, special measures can be taken, including the use of clinical guidelines, modification of the discharge process, and modification of the lower levels of the service providing system.

Trends over 42 years in the Adult Medical Genetics Clinic at the University of Washington.

PURPOSE: We analyzed the patients served by the University of Washington Adult Genetic Medicine Clinic (UWAGMC) over a 42-year period to determine how clinical services have changed and to evaluate the contributing factors. METHODS: We conducted a retrospective survey of patients seen by UWAGMC that included patients seen from 1975 to 2016. Variables considered included referral indication, disease status, and clinic visit date. Indications for referral were then binned into clinical categories for descriptive analysis. RESULTS: Of 30,780 patient visits during the 39 years for which data were available, 57.3% occurred in the last decade. Referrals for breast/ovarian cancer or colon/endometrial cancer account for 74.8% of cancer referrals since 1998. Huntington disease patients made up 46% of neurological referral indications. Telephone screening implemented in 2013 has reduced the number of referrals for hypermobile Ehlers-Danlos syndrome. CONCLUSION: Referral indications increased with clinical testing availability and because of the academic programs of UWAGMC providers. With increased public awareness of heritable conditions, prescreening self-referrals were used to allocate limited resources. These trends demonstrate the need for more geneticists in adult medicine to expand centers of excellence for rare diseases and to serve the increasing numbers of adult patients with genetic conditions.

Guidance on guidelines: Understanding the evidence on the uptake of health care guidelines.

RATIONALE: Regardless of health issue, health sector, patient condition, or treatment modality, the chances are that provision is supported by "a guideline" making professionally endorsed recommendations on best practice. Against this background, research has proliferated seeking to evaluate how effectively such guidance is followed. These investigations paint a gloomy picture with many a guideline prompting lip service, inattention, and even opposition. This predicament has prompted a further literature on how to improve the uptake of guidelines, and this paper considers how to draw together lessons from these inquiries. METHODS: This huge body of material presents a considerable challenge for research synthesis, and this paper produces a critical, methodological comparison of 2 types of review attempting to meet that task. Firstly, it provides an overview of the current orthodoxy, namely, "thematic reviews," which aggregate and enumerate the "barriers and facilitators" to guideline implementation. It then outlines a "realist synthesis," focussing on testing the "programme theories" that practitioners have devised to improve guideline uptake. RESULTS: Thematic reviews aim to provide a definitive, comprehensive catalogue of the facilitators and barriers to guideline implementation. As such, they present a restatement of the underlying problems rather than an improvement strategy. The realist approach assumes that the incorporation of any guideline into current practice will produce unintended system strains as different stakeholders wrestle over responsibilities. These distortions will prompt supplementary revisions to guidelines, which in turn beget further strains. Realist reviews follow this dynamic understanding of organisational change. CONCLUSIONS: Health care decision makers operate in systems that are awash with guidelines. But guidelines only have paper authority. Managers do not need a checklist of their pros and cons, because the fate of guidelines depends on their reception rather than their production. They do need decision support on how to engineer and reengineer guidelines so they dovetail with evolving systems of health care delivery.

Comparison of the EQ-5D-3L and the SF-6D (SF-12) contemporaneous utility scores in patients with cardiovascular disease.

PURPOSE: Multi-attribute utility instruments (MAUIs) are widely used to measure utility weights. This study sought to compare utility weights of two popular MAUIs, the EQ-5D-3L and the SF-6D, and inform researchers in the selection of generic MAUI for use with cardiovascular (CVD) patients. METHODS: Data were collected in the Young@Heart study, a randomised controlled trial of a nurse-led multidisciplinary home-based intervention compared to standard usual care. Participants (n = 598) completed the EQ-5D-3L and the SF-12v2, from which the SF-6D can be constructed, at baseline and at 24-month follow-up. This study examined discrimination, responsiveness, correlation and differences across the two instruments. RESULTS: Both MAUIs were able to discriminate between the NYHA severity classes and recorded similar changes between the two time points although only SF-6D differences were significant. Correlations between the dimensions of the two MAUIs were low. There were significant differences between the two instruments in mild conditions but they were similar in severe conditions. Substantial ceiling and floor effects were observed. CONCLUSIONS: Our findings indicate that the EQ-5D and the SF-6D cover different spaces in health due to their classification systems. Both measures were capable of discriminating between severity groups and responsive to quality of life changes in the follow-up. It is recommended to use the EQ-5D-3L in severe and the SF-6D in mild CVD conditions.

The Effect of Utilization Review on Emergency Department Operations.

STUDY OBJECTIVE: Increasingly, hospitals are using utilization review software to reduce hospital admissions in an effort to contain costs. Such practices have the potential to increase the number of unsafe discharges, particularly in public safety-net hospitals. Utilization review software tools are not well studied with regard to their effect on emergency department (ED) operations. We study the effect of prospectively used admission decision support on ED operations. METHODS: In 2012, Los Angeles County + University of Southern California Medical Center implemented prospective use of computerized admission criteria. After implementation, only ED patients meeting primary review (diagnosis-based criteria) or secondary review (medical necessity as determined by an on-site emergency physician) were assigned inpatient beds. Data were extracted from electronic medical records from September 2011 through December 2013. Outcomes included operational metrics, 30-day ED revisits, and 30-day admission rates. Excluding a 6-month implementation period, monthly summary metrics were compared pre- and postimplementation with nonparametric and negative binomial regression methods. All adult ED visits, excluding incarcerated and purely behavioral health visits, were analyzed. The primary outcomes were disposition rates. Secondary outcomes were 30-day ED revisits, 30-day admission rate among return visitors to the ED, and estimated cost. RESULTS: Analysis of 245,662 ED encounters was performed. The inpatient admission rate decreased from 14.2% to 12.8%. Increases in discharge rate (82.4% to 83.4%) and ED observation unit utilization (2.5% to 3.4%) were found. Thirty-day revisits increased (20.4% to 24.4%), although the 30-day admission rate decreased (3.2% to 2.8%). Estimated cost savings totaled $193.17 per ED visit. CONCLUSION: The prospective application of utilization review software in the ED led to a decrease in the admission rate. This was tempered by a concomitant increase in ED observation unit utilization and 30-day ED revisits. Cost savings suggest that resources should be redirected to the more highly affected ED and ED observation unit, although more work is needed to confirm the generalizability of these findings.

Quarterly Reporting of Computed Tomography Ordering History Reduces the Use of Imaging in an Emergency Department.

BACKGROUND: Computed tomography (CT) is a useful and necessary part of many emergency department (ED) assessments. However, the costs of imaging and the health risks associated with radiation exposure have sparked national efforts to reduce CT ordering in EDs. STUDY OBJECTIVE: We analyzed CT ordering habits prior to and following implementation of a feedback tool at a community hospital. METHODS: In this intervention study, we identified the CT-ordering habits of physicians and mid-level care providers (physician assistants and nurse practitioners) at baseline and after implementation of a system that sent quarterly feedback reports comparing their ordering habits with those of their peers. Variability in ordering and subgroup analyses by body region were included in these reports. RESULTS: We examined the records of 104,454 patients seen between October 1, 2013 and December 31, 2014. There were 5552 or 21.0% of patients seen during the baseline period that underwent CT imaging. We observed an absolute reduction in imaging of 2.3% (95% confidence interval 1.7-2.8%) after implementation, avoiding approximately $400,000 in costs, 22 days of scanning time, and radiation exposure equivalent to 33,000 chest films annually. These changes occurred across physicians and mid-level providers, regardless of the number years of practice or board certification. CONCLUSIONS: Implementation of a feedback mechanism reduced CT use by emergency medicine practitioners, with concomitant reductions in cost and radiation exposure. The change was similar across levels of medical care. Future studies will examine the effect of the feedback reporting system at other institutions in our hospital network.

Intensive Care Unit Utilization and Mortality Among Medicare Patients Hospitalized With Non-ST-Segment Elevation Myocardial Infarction.

Importance: Intensive care unit (ICU) utilization may have important implications for the care and outcomes of patients with non-ST-segment elevation myocardial infarction (NSTEMI). Objectives: To examine interhospital variation in ICU utilization in the United States for older adults with hemodynamically stable NSTEMI and outcomes associated with ICU utilization among patients with low, moderate, or high mortality risk. Design, Setting, and Participants: This study was a retrospective analysis of 28 018 Medicare patients 65 years or older admitted with NSTEMI to 346 hospitals participating in the Acute Coronary Treatment and Intervention Outcomes Network (ACTION)-Get With the Guidelines from April 1, 2011, through December 31, 2012. Patients with cardiogenic shock or cardiac arrest on presentation were excluded. Data analysis was performed from May 7 through October 8, 2015. Exposures: Hospitals with high (>70% of patients with NSTEMI treated in an ICU during the index hospitalization), intermediate (30%-70%), or low (<30%) ICU utilization. Main Outcomes and Measures: Thirty-day mortality. Results: Of 28 018 patients with NSTEMI 65 years or older (median age, 77 years [interquartile range, 71-84 years]; female, 13 055 [46.6%]; nonwhite race, 3931 [14.0%]), 11 934 (42.6%) had an ICU stay. The proportion of patients with NSTEMI treated in the ICU varied across hospitals (median, 38%; interquartile range, 26%-54%), but no significant differences were found in hospital or patient characteristics among high, intermediate, or low ICU utilization hospitals. Compared with high ICU utilization hospitals, low or intermediate ICU utilization hospitals were only marginally more selective of higher-risk patients, as determined by ACTION in-hospital mortality risk score or initial troponin level. The median ACTION risk score for patients treated in the ICU at low and intermediate ICU utilization hospitals was 34 compared with 33 for patients not treated in the ICU; at high ICU utilization hospitals, the median ACTION mortality risk score was 33 for patients treated in the ICU and 34 for patients not treated in the ICU. Thirty-day mortality rates did not significantly differ based on hospital ICU utilization (high vs low: 8.7% vs 8.7%; adjusted odds ratio, 0.91; 95% CI, 0.76-1.08; intermediate vs low: 9.6% vs 8.7%; adjusted odds ratio, 1.06; 95% CI, 0.94-1.20). The association between hospital ICU utilization and mortality did not change when considered among patients with ACTION risk scores greater than 40, 30 to 40, and less than 30 (adjusted interaction P = .86). Conclusions and Relevance: Utilization of the ICU for older patients with NSTEMI varied significantly among hospitals. This variability was not explained by hospital characteristics or driven by patient risk. Mortality after myocardial infarction did not significantly differ among high, intermediate, or low ICU utilization hospitals.

Health Care Access and Utilization Among Adults Aged 18-64, by Poverty Level: United States, 2013-2015.

KEY FINDINGS: Data from the National Health Interview Survey, 2013-2015 •From 2013 through 2015, the percentage of adults aged 18-64 who were uninsured at the time of interview decreased for poor (40.0% to 26.2%), near-poor (37.8% to 23.9%), and not-poor (11.7% to 7.7%) adults. •The percentage of adults aged 18-64 who had a usual place to go for medical care increased for poor (66.9% to 73.6%) and near-poor (71.1% to 75.9%) adults. •The percentage of adults aged 18-64 who had seen or talked to a health professional in the past 12 months increased for poor (73.2% to 75.8%) and near-poor (71.9% to 75.9%) adults. •The percentage of adults aged 18-64 who did not obtain needed medical care due to cost at some time during the past 12 months decreased for poor (16.8% to 12.4%), near-poor (14.6% to 11.0%), and not-poor (4.9% to 3.8%) adults. In 2014, U.S. adults could purchase a private health insurance plan through the Health Insurance Marketplace or state-based exchanges established as part of the Affordable Care Act (ACA). Additionally, under ACA some states opted to expand Medicaid coverage to low-income adults. Individuals living in or near poverty may have benefited disproportionately from these changes given their lower rates of health insurance coverage (1). Data from the 2013-2015 National Health Interview Survey (NHIS) are used to describe recent changes in health insurance coverage and selected measures of health care access and utilization for adults aged 18-64 by family poverty level.

Descriptive Characteristics and Amputation Rates With Use of Intrepid Dynamic Exoskeleton Orthosis.

Advancements in ankle-foot orthotic devices, such as the Intrepid Dynamic Exoskeletal Orthosis (IDEO), are designed to improve function and reduce pain of the injured lower extremity. There is a paucity of research detailing the demographics, injury patterns and amputation outcomes of patients who have been prescribed an IDEO. The purpose of this study was to describe the demographics, presenting diagnosis and patterns of amputation in patients prescribed an IDEO at the Center for the Intrepid (CFI). The study population was comprised of 624 service members who were treated at the CFI and prescribed an IDEO between 2009 and 2014. Data were extracted from the Expeditionary Medical Encounter Database, Defense Manpower Data Center, Military Health System Data Repository, and CFI patient records for demographic and injury information as well as an amputation outcome. The most common injury category that received an IDEO prescription was injuries at or surrounding the ankle joint (25.0%), followed by tibia injuries (17.5%) and nerve injuries below the knee (16.4%). Over 80% of the sample avoided amputation within a one year time period using this treatment modality. Future studies should longitudinally track IDEO users for a longer term to determine the long term viability of the device.

Evaluating Two Measures of Lumbar Spine MRI Overuse: Administrative Data Versus Chart Review.

PURPOSE: Lumbar spine (LS) MRI overuse may be identified in administrative data, but these data may lack the detailed clinical information needed to correctly assess overuse. The aim of this study was to compare chart review with analysis of administrative data to determine the appropriateness of LS MRI. METHODS: The sensitivity and specificity of the administrative method were determined, with inappropriateness regarded as the positive result, as if chart review determined the true state. Patients were the first 146 veterans who underwent LS MRI in the outpatient setting in fiscal year 2012 at the Veterans Affairs Palo Alto Health Care System. The InterQual criteria for chart review and the method of evaluating administrative data developed by CMS and endorsed by the National Quality Forum were used. Slight modifications were made to each measure to ensure completeness and comparability. RESULTS: Of the 146 scans reviewed, 23% were considered inappropriate by the administrative measure, whereas 59% were considered inappropriate by chart review. Compared with chart review, the administrative measure had specificity of 82% for identifying inappropriate scans and sensitivity of 27% for identifying appropriate scans. CONCLUSIONS: Compared with chart review, analysis of administrative data identified scans that were appropriate but underestimated inappropriate ordering. Contrary to expectations, chart review resulted in more scans being classified as inappropriate. The administrative method is economically feasible for identifying the overuse of LS MRI, but it underestimates the true extent of inappropriate ordering.

[Challenges in the Analysis of Health Care Inequalities in Pediatric Rehabilitation]. / Herausforderungen in der Analyse von Versorgungsungleichheiten in der Kinderrehabilitation.

BACKGROUND: Social inequalities on access and utilization of inpatient rehabilitation among adolescents have rarely been studied. METHODS: Parents of children with chronic health conditions (age of 7-17) were interviewed about access and utilization of inpatient rehabilitation. Parents were recruited through pediatricians as well as rehabilitation centers in Central Germany. RESULTS: Despite of numerous recruitment measures the participation by pediatricians was low. Also expanding the sample did not remedial. Furthermore, fewer adolescents with need of rehabilitation were achieved than expected. The analysis is subject to these restrictions, nevertheless, they still allow explorative statements about access and utilization of pediatric rehabilitation. CONCLUSION: Despite major challenges in recruitment, pediatricians should be considered into analysis of inequalities in rehabilitation because of their gatekeeper function.

14 Years longitudinal evaluation of clinical information systems acceptance: The HEGP case.

CONTEXT: Meaningful use and end-user satisfaction are two major components of the success of a clinical information system (CIS). The purpose of this study was to longitudinally measure and analyze the CIS use and satisfaction determinants in a multi-professional group at the Georges Pompidou university hospital (HEGP) in Paris. METHODS: From the different evaluation surveys performed at HEGP, three periods were considered corresponding to 4, 8 and over 10 years after the first CIS deployment in 2000, respectively. Six acceptance dimensions were considered: CIS quality (CISQ), facilitating conditions (FC), perceived usefulness (PU), confirmation of expectations (CE), use, and global satisfaction (GS). Relationships between these constructs were tested through multiple regressions analysis and structural equation modeling (SEM). RESULTS: Responses were obtained from 298, 332, and 448 users for the three periods considered. CIS acceptance dimensions progressively and significantly increased over time. Significant differences between professions were observed with an initial low PU among medical staff. In the early deployment phase, GS appeared to be determined by CIS use, CISQ and PU (R(2)=.53 in SEM). In the very late post-adoption phase, GS was strongly determined by CISQ, CE, and PU (R(2)=.86 in SEM) and was no longer associated with CIS use. CONCLUSION: Acceptance models should be adapted to the phase of deployment of a CIS and integrate end-users' individual characteristics. Progressive reduction over time of the positive relationships between CIS use and satisfaction could possibly be considered as a maturity indicator of CIS deployment. These observations validate the introduction in post-adoption models of a continuance intention dimension.

Mobile Usability Testing in Healthcare: Methodological Approaches.

The use of mobile devices and healthcare applications is increasing exponentially worldwide. This has lead to the need for the healthcare industry to develop a better understanding of the impact of the usability of mobile software and hardware upon consumer and health professional adoption and use of these technologies. There are many methodological approaches that can be employed in conducting usability evaluation of mobile technologies. More obtrusive approaches to collecting study data may lead to changes in study participant behaviour, leading to study results that are less consistent with how the technologies will be used in the real-world. Alternatively, less obstrusive methods used in evaluating the usability of mobile software and hardware in-situ and laboratory settings can lead to less detailed information being collected about how an individual interacts with both the software and hardware. In this paper we review and discuss several innovative mobile usability evaluation methods on a contiuum from least to most obtrusive and their effects on the quality of the usability data collected. The strengths and limitations of methods are also discussed.

Evidence-based Heuristics for Evaluating Demands on eHealth Literacy and Usability in a Mobile Consumer Health Application.

Heuristic evaluations have proven to be valuable for identifying usability issues in systems. Commonly used sets of heuritics exist; however, they may not always be the most suitable, given the specific goal of the analysis. One such example is seeking to evaluate the demands on eHealth literacy and usability of consumer health information systems. In this study, eight essential heuristics and three optional heuristics subsumed from the evidence on eHealth/health literacy and usability were tested for their utility in assessing a mobile blood pressure tracking application (app). This evaluation revealed a variety of ways the design of the app could both benefit and impede users with limited eHealth literacy. This study demonstrated the utility of a low-cost, single evaluation approach for identifying both eHealth literacy and usability issues based on existing evidence in the literature.
