“…Among the methods used to evaluate system usability, the methods that involve present users in the real world provide a better understanding of system usability. Previous studies [54][55][56][57] have shown that think aloud method identifies many problems related to usability and identifies the root cause of the problems. Thus, this study used think aloud method to evaluate the application and the identified usability problems were solved.…”

Background Medication dosage calculation errors are among the most common errors of nurses in intensive care unit (ICU). Information technologies, particularly mobile devices, can advance drug dosage calculation processes. The objective of this study was to develop a medication dosage calculation application for nurses in intensive care units. Methods This study was performed in the ICUs of teaching hospitals in Kerman University of Medical Sciences in 2018. First, a need assessment survey of nurses was conducted to determine the required features of the application. As well two specialists were interviewed to determine the medications used in the ICUs. Second, a medication dosage calculation application was developed using formative usability testing. Results Overall, 80% of the participants (n=120) answered the need assessment questionnaire. Of 29 features determined in the needs assessment, 19 were selected to develop the application. Moreover, 25 medications were selected by specialists and participants for the development of the application and its prototype. The usability test of the prototype found 15 problems. After fixing these problems 2 problems were identified, which were fixed in the final version. Conclusion According to the participants, development of the medication dosage calculation application increases the accuracy of drug dosage and reduces the errors. The user-identified features were developed in-app. User-centered usability testing in this study improved development based on needs of users. The method used in this study can be used by developers of health applications to develop applications which are consistent with user needs.

“…The usability of the app has been previously evaluated with South African users, both emergency doctors and burns specialists. 27 In another study by Blom et al, South African burns and emergency care specialists believed the app would streamline the diagnostic process, improve both triage and referrals, and be a more secure option for remote diagnosis compared with current practices. 28…”

Introduction: The rapid adoption of smartphones, especially in low-and middle-income countries, has opened up novel ways to deliver health care, including diagnosis and management of burns. This study was conducted to measure acceptability and to identify factors that influence health care provider's attitudes toward m-health technology for emergency care of burn patients. Methods: An extended version of the technology acceptance model (TAM) was used to assess the acceptability toward using m-health for burns. A questionnaire was distributed to health professionals at four hospitals in Dar Es Salaam, Tanzania. The questionnaire was based on several validated instruments and has previously been adopted for the sub-Saharan context. It measured constructs, including acceptability, usefulness, ease of use, social influences, and voluntariness. Univariate analysis was used to test our proposed hypotheses, and structural equation modeling was used to test the extended version of TAM. Results: In our proposed test-model based on TAM, we found a significant relationship between compatibility-usefulness and usefulness-attitudes. The univariate analysis further revealed some differences between subgroups. Almost all health professionals in our sample already use smartphones for work purposes and were positive about using smartphones for burn consultations. Despite participants perceiving the application to be easy to use, they suggested that training and ongoing support should be available. Barriers mentioned include access to wireless internet and access to hospital-provided smartphones.

“…mHealth is also increasingly used to aid physicians in their medical decision making [ 48 ] and to facilitate consultations with other providers and experts in their areas of expertise [ 49 , 50 ], highlighting the broad applicability of mHealth, not only for patients but also for medical providers. In a survey of health care providers, more than 70% of physicians had smartphones, and 77% of nurses and doctors used medical apps [ 51 ].…”

Integration of Mobile Health Into Sickle Cell Disease Care to Increase Hydroxyurea Utilization: Protocol for an Efficacy and Implementation Study

et al. 2020

Background Hydroxyurea prevents disease complications among patients with sickle cell disease (SCD). Although its efficacy has been endorsed by the National Health Lung and Blood Institute evidence-based guidelines, its adoption is low, both by patients with SCD and providers. Mobile health (mHealth) apps provide benefits in improving medication adherence and self-efficacy among patients with chronic diseases and have facilitated prescription among medical providers. However, mHealth has not been systematically tested as a tool to increase hydroxyurea adherence nor has the combination of mHealth been assessed at both patient and provider levels to increase hydroxyurea utilization. Objective This study aims to increase hydroxyurea utilization through a combined two-level mHealth intervention for both patients with SCD and their providers with the goals of increasing adherence to hydroxyurea among patients and improve hydroxyurea prescribing behavior among providers. Methods We will test the efficacy of 2 mHealth interventions to increase both patient and provider utilization and knowledge of hydroxyurea in 8 clinical sites of the NHLBI-funded Sickle Cell Disease Implementation Consortium (SCDIC). The patient mHealth intervention, InCharge Health, includes multiple components that address memory, motivation, and knowledge barriers to hydroxyurea use. The provider mHealth intervention, Hydroxyurea Toolbox (HU Toolbox), addresses the clinical knowledge barriers in prescribing and monitoring hydroxyurea. The primary hypothesis is that among adolescents and adults with SCD, adherence to hydroxyurea, as measured by the proportion of days covered (the ratio of the number of days the patient is covered by the medication to the number of days in the treatment period), will increase by at least 20% after 24 weeks of receiving the InCharge Health app, compared with their adherence at baseline. As secondary objectives, we will (1) examine the change in health-related quality of life, acute disease complications, perceived health literacy, and perceived self-efficacy in taking hydroxyurea among patients who use InCharge Health and (2) examine potential increases in the awareness of hydroxyurea benefits and risks, appropriate prescribing, and perceived self-efficacy to correctly administer hydroxyurea therapy among SCD providers between baseline and 9 months of using the HU Toolbox app. We will measure the reach, adoption, implementation, and maintenance of both the InCharge Health and the HU Toolbox apps using the reach, effectiveness, adoption, implementation, and maintenance framework and qualitatively evaluate the implementation of both mHealth interventions. Results The study is currently enrolling study participants. Recruitment is anticipated to be completed by mid-2021. Conclusions If this two-level intervention, that is, the combined use of InCharge Health and HU Toolbox apps, demonstrates efficacy in increasing adherence to hydroxyurea and prescribing behavior in patients with SCD and their providers, respectively, both apps will be offered to other institutions outside the SCDIC through a future large-scale implementation-effectiveness study.
