Abstract

Aim

The aim of this study was to provide evidence of the impact of mobile technologies among healthcare professionals in education and practice settings.

Design

Integrative literature review.

Methods

Electronic databases including MEDLINE, CINAHL, PsycINFO, EMBASE, ERIC and Web of Science were searched for papers published between 2002–2012. Quantitative studies were critically evaluated based on Thomas et al.s framework, while the consolidated criteria for reporting qualitative research was used to appraise the rigour of the qualitative studies.

Results

Seventeen quantitative and three qualitative studies were included. The findings suggest a largely positive influence of mobile technologies on various clinical practice and educational outcomes. However, robust evidence was limited. Use of mobile technologies in health care are associated with improvements in access to information, accuracy and efficiency, evidence-based decision making at the point of care and enhancement in performance, confidence and engagement in different contexts.

Introduction

Since the introduction of mobile technologies in the early 1990s, it has become a valuable and important tool to be incorporated into various medical-related fields used by multiple disciplines (Ranson et al. 2007). Mobile devices can now store large quantities of information. Their operating systems allow applications that support sophisticated user interactions, their graphics capabilities offer representational versatility and their networked status means that they afford easy communication among their users (Walton et al. 2005). Moreover, many healthcare professionals (HCPs) will have acquired a degree of familiarity and confidence with such devices through their own personal and recreational uses, so it is easy to argue that this use should be extended to support the education and practice of HCPs.

Various scoping studies (Khan et al. 2007, Crook et al. 2012, Franko & Tirrell 2012) have identified a range of medical software applications available to HCPs. Most applications are information reference points or quizzes, exam or test your knowledge type software applications. However, evidence of their impact on learning and practice among healthcare professionals is limited.

Several reviews showed that personal digital assistants (PDAs) were being increasingly integrated into clinical practice and medical education (Garritty & El Emam 2006). A PDA is a generic term for any small mobile handheld device including smartphones and tablets that provides computing and information storage and retrieval capabilities for personal or business use, often for keeping schedule calendars and address book information handy (Luanrattana et al. 2007). However, none of these provided a comprehensive overview of the use of mobile technologies among healthcare professionals with a focus on its use in improving education and clinical practice. Traditionally, systematic reviews have heavily relied on evidence obtained from quantitative studies. However, this is becoming increasingly important to recognize the benefit of integrating qualitative and quantitative research evidence (Centre for Review and Dissemination 2008). A review can be enhanced when qualitative studies which explore peoples experiences and perceptions of a subject area are included. It is particularly true when limited evidence derived from trials is anticipated such as evidence in relation to the impact of mobile technologies. Therefore, to provide a wider overview of this topic, an integrative review was conducted by integrating evidence from both quantitative and qualitative research.

This present review aims to raise the awareness among differing healthcare professionals about the importance of mobile technologies and the potential roles in education and clinical practice settings and provide evidence to support its use. In addition, this review would encourage the further evaluation of the use of mobile technologies and inform the development of specific mobile applications for future education and practice across a range of healthcare professionals.

Aims

The overarching aim of this review was to identify evidence focusing on the use of mobile technologies in education and practice settings by healthcare professionals. Specifically, the review sought to:

  • Examine the impact of mobile technologies on clinical and educational outcomes in healthcare professionals.
  • Identify the extent to which quantitative outcomes addressing aspects of clinical and/or educational significance have been used in previous studies.
  • Identify the extent to which qualitative evaluation of aspects of clinical and/or educational significance has been explored in previous studies.

Given the aim to capture a comprehensive review of studies in this area, the research question which guided this review was what international evidence exists on the impact of mobile technologies and experience of using mobile technologies in any education and practice settings among different groups of healthcare professionals.

Methods

Design

An integrative literature review was conducted to capture all studies evaluating mobile technologies used by healthcare professionals in education and practice settings. Due to the complex nature of this topic, we included all relevant quantitative and qualitative evidence. Review methods recommended by the Centre for Review and Dissemination were adopted to help specify clear and reproducible eligibility criteria for selection of studies, comprehensively search and retrieve relevant studies that met the eligibility criteria, critically appraise the quality of included studies and synthesize findings (Centre for Reviews and Dissemination 2008).

Search strategy

A comprehensive search strategy was developed to obtain all relevant studies using terms addressing the study focus (e.g. ‘impact’/‘mobile technologies’, ‘smartphones and software applications’, ‘handheld computers’, ‘personal digital assistants (PDAs)’/‘experience’/‘health professionals’). The search was conducted between April and August 2012. The search terms (subject headings or key words) including quantitative (‘evaluation’) and qualitative outcomes (‘perceptions’) were used to map to the title, abstract and full text for identifying both types of studies. Electronic databases including MEDLINE, CINAHL, PsycINFO, EMBASE, ERIC and Web of Science were searched. All searches were screened and duplicated studies were discarded. Reference lists of all retrieved articles were followed up to identify additional studies pertinent to the topic area.

Inclusion and exclusion criteria

Studies were included in the review if they met the following criteria: the studies: (1) were published in English between 2002-2012; (2) involved healthcare professionals; (3) were primary research. Commentary and anecdotal articles were excluded. The specific selection criteria were also applied, according to study design:

Quantitative studies
  • Participants – healthcare professionals.
  • Intervention – the introduction of mobile technologies.
  • Outcomes – student, faculty, clinical staff or service and cost outcomes in education and/or clinical practice.
  • Study design – comparison study, or a survey without a comparison group.
Qualitative studies
  • Participants – healthcare professionals.
  • Study design – Qualitative exploration of the perceptions or experience of students, faculty members or clinical staff about mobile technologies.

In this review, we categorized the educational outcomes according to Kirkpatricks four-level training evaluation model (Kirkpatrick 1994). When moving from level 1 to level 4, the methodologies required to achieve the outcomes tend to become more complex, however, the potential benefits and impacts for patients and healthcare organizations are greater. Four levels include:

  • level 1 reaction: participants’ initial reactions or satisfaction, usually assessed through surveys and focus groups.
  • level 2 learning: the amount of knowledge and skills that participants learnt, usually assessed through pre-/post tests, observations and interviews.
  • level 3 transfer: participants’ use of the knowledge and skills gained in everyday life, usually assessed through observations, interviews and surveys.
  • level 4 dissemination and value to the organization: cost-effectiveness and organisational benefits. Assessment for this level is not clearly defined but the more qualitative approaches using action research and critical incidents were seen to be a better approach to this level.

The focus of this evaluation model is on measuring four kinds of outcomes that should result from a highly effective training programme. There is a potential outcome line that ends with the level four results:

Training programme → Reactions → Learning → Transfer (behaviour) → Dissemination and value to the organization (increased productivity and profits).

Learning (level 2 outcomes) and transfer of learning (level 3 outcomes) are unlikely to occur unless participants have positive attitudes towards the training programme (level 1 outcomes). For dissemination and value to the organization (level 4 outcomes) to take place, there must be many intervening factors involved. This means that we should not be overly optimistic in expecting large level four outcomes from single training programmes.

Search outcome

The titles and abstracts of 112 potentially relevant studies were independently reviewed by two reviewers (PG and KW) against the selection criteria and reasons for exclusion after evaluation of abstracts were recorded. Any discrepancies were discussed with a third reviewer (HW) to reach a final agreement. The full texts of 73 studies were retrieved and reviewed in further detail. Of these, 53 articles were excluded as they did not meet the inclusion criteria. Consequently, 20 primary studies published between 2002–2012 were identified and included in the review (Figure 1). These included: 17 quantitative (4 comparison studies; 13 descriptive surveys or studies without a comparison group) and three qualitative studies.

Quality appraisal

Quantitative studies were critically evaluated based on a framework (Table 1) recommended by Thomas et al. (2003) while the consolidated criteria for reporting qualitative research (COREQ) (Table 2) was used to appraise the rigour of the qualitative studies (Tong et al. 2007). Thomas et al.s framework was developed to be an appropriate quality assessment tool to encompass a variety of research designs (not only randomized controlled trials but also non-randomized studies). It has been proved to have good content and construct validity and intrarater reliability and is relatively easy to use (Thomas et al. 2004). The quality of the studies varied.

Quantitative studies

Quality was relatively weak: three studies using a comparison group (Miller et al. 2005, Greenfield 2007, Flannigan & McAloon 2011) were non-randomized quasi-experimental studies. Only one study (Tews et al. 2011) applied the procedure of randomization but suffered with a small sample size of 22. Uncontrolled pre- and post tests designs were used in most studies. The included studies did not report details of confounding variables so there was insufficient information provided regarding whether or not groups were comparable at baseline. The areas such as selection bias, blinding and allocation concealment and data collection methods were poorly reported. In addition, all studies did not use strict ‘intention to treat’ analysis and did not explain how missing data and/or deviation from protocol or withdrawals/dropouts were analysed.

Thirteen surveys generally described clear objectives and design. However, sample sizes of these studies were often small (n = 10-3306) and few studies attempted to explore the participants’ and non-responders’ representativeness of the target population. Most studies involved non-validated questionnaires or were unclear whether the measurement tools were valid or not. Therefore, it is recognized that the generalizability of these studies was limited.

Qualitative studies

All three studies (Garrett & Jackson 2006, Fisher & Koren 2007, Garrett & Klein 2008) had a clear description of aims and study design as well as an explicit sampling rationale. In these studies, the data collection and analysis methods were often clearly and transparently described. All studies obtained ethical approval but only one study (Garrett & Jackson 2006) explicitly reported possible ethical issues involved throughout the study. No studies included any consideration of reflexivity, however, most findings were presented clearly and the research provided valuable qualitative evidence.

Data abstraction

A data abstraction form was developed using the Centre for Review and Dissemination (CRD) guidelines for undertaking reviews in health care (Centre for Reviews and Dissemination 2008). The form was used to record full study details and guide decision about the relevance of individual studies to the review questions. Similar information was abstracted for all studies and included: study design, setting, speciality, aim, study participants, results and conclusions. Data were abstracted and charted by PG and checked by KW or HW. Disagreements were addressed through consensus. Table 3 presents a full description of the included studies according to study design. Qualitative comments reported in quantitative studies were jointly extracted but we focused on the quantitative results.

Synthesis

The studies that met the selection criteria measured various outcomes ranging from clinical outcomes to educational outcomes. Therefore, it was decided not to pool the results using meta-analysis but summarize them descriptively. Despite the current lack of guidance on the synthesis of diverse data sources in a sing review (Goldsmith et al. 2007), we decided to adopt a robust two step approach. The first step in the synthesis process was to construct a tabular summary of all studies related to key information including the study designs, countries, aims, specialist areas, study participants and results (Table 3). An overarching synthesis was subsequently carried out to bring quantitative and qualitative evidence together to explore the impact of mobile technologies further on both clinical outcomes (Table 4) and educational outcomes (Table 5).

Results

The studies (17 quantitative and three qualitative studies) had been conducted in a range of countries: 15 studies (14 quantitative and one qualitative) were set in USA; two quantitative studies were conducted in the UK; three studies in Canada (one quantitative and the other two qualitative). The review showed that use of mobile technologies has primarily been focused in the studies conducted in the USA. It is also apparent that in the healthcare context, the PDA is the most commonly used mobile technology up to the search date of this review.

The studies were undertaken in a variety of specialist areas, including paediatrics, emergency medicine, nephrology, cardiology, endocrinology and primary care. Nine studies evaluated the use and impact of mobile technologies among medical staff and medical students primarily at the undergraduate level and in the hospital environment, while eleven studies concentrated on nurses and pre-registration nursing students. Other HCPs were less well represented. Only one study focused on the potential of mobile technologies to meet the needs of community health students on access to learning resource (Walton et al. 2005). The use of mobile technologies in emergency medicine was evaluated in three studies (Khan et al. 2007, Flannigan & McAloon 2011, Tews et al. 2011), of which two studies had a focus on paediatrics and emergency medicine (Khan et al. 2007, Flannigan & McAloon 2011).

There would appear to be equal importance of mobile technologies in both clinical applications and learning applications. Outcomes measured in the included studies varied but generally fell into the following two categories: clinical practice outcomes and educational outcomes. Table 4 presents the summary of impact of mobile technologies for clinical practice outcomes. Table 5 illustrates that mobile technologies have indicators of impact on educational outcomes.

In the clinical setting, several quantitative/survey studies identified that there were increasing trends for use of PDAs in clinical practice, decisions support (e.g. Rothschild et al. 2002, Stroud et al. 2005, 2009), patient education, teaching medical students (e.g. Khan et al. 2007, Morris et al. 2007, Franko & Tirrell 2012) and the development and use of future software applications. Four studies suggested that the use of PDAs had resulted in decreasing medical errors, increasing efficiency and promoting patient safety (Rothschild et al. 2002, Carroll & Christakis 2004, Stroud et al. 2009, Flannigan & McAloon 2011). Two qualitative studies suggested that PDAs had an impact on improved professional image and improved patients’ quality of care (Fisher & Koren 2007, Garrett & Klein 2008).

In terms of educational outcomes, the use of mobile technologies is concentrated on learning experience and students’ satisfaction (e.g. Miller et al. 2005, Maag 2006, Kenny et al. 2009). Improvements in learning were evident including learning accuracy and efficiency (Greenfield 2007, George et al. 2010), examining critical thinking and communication skills (Fisher & Koren 2007) and clinical learning and engagement (Garrett & Jackson 2006, Tews et al. 2011).

According to Kirkpatricks four-level training evaluation model, most of the studies included in the review measured level 1 – reaction outcomes which could be potentially biased by self-perception. Only two quantitative studies assessed level 2 – learning outcomes (the amount of skills and knowledge that participants learnt) and indicated increased accuracy and speed (Greenfield 2007) and improved case presentation performance and confidence (Tews et al. 2011). No level 3 and 4 outcomes were measured in any included studies.

Discussion

Twenty studies were identified and included in the review. However, methodological quality of these studies was relatively weak, especially in the studies with quantitative design. The findings of the review showed positive outcomes of using mobile technologies in both education and clinical settings. However, all studies were conducted in western, developed countries and were US centric. Limited evidence has been found on evaluation of their use and incorporation into healthcare professionals’ educational programmes, particularly allied health professionals’ education and training and its impact on patient outcomes and learning outcomes. These will be further discussed in the following three areas: the use of mobile technologies to aid engagement with learning; benefits of mobile technologies in clinical practice; adoption of mobile technologies in health care and barriers to mobile technology adoption.

Use of mobile technologies to aid learning engagement

A growing body of literature draws attention to the potential of mobile technologies for the support of learning. A review of the impact of PDAs highlighted that the integration of PDA technology into medical education has a valuable contribution to residency training programmes, particularly graduate medical training (Tempelhof 2009).

Several articles also showed that integration of mobile technologies in nursing curricula allowed students to actively participate in different learning contexts and reinforce what they have learnt at any time or any location (Miller et al. 2005). Personal mobile devices such as smartphones can be used for immediate and constant access to information or materials, current evidence and guidelines in academic and clinical settings. An advantage was that students were able to view instructional videos before performing clinical tasks and timely approach their instructor via text message (Maag 2006, Kenny et al. 2009). A qualitative study in the review (Fisher & Koren 2007) conducted with 28 students in the third and fourth year of an undergraduate baccalaureate nursing clinical education programme found that the PDAs were successfully integrated into nursing education in the use of several reference resources such as drug guides/administration, medical dictionaries and patient information materials.

Benefits of mobile technologies in clinical practice

Accurate patient care documentation and information are increasingly emphasized in health care. Frequently updated clinical guidelines further challenge healthcare professionals’ efficiency in daily practice. Sophisticated handheld devices have been developed and used to store patient information as well as monitor and keep healthcare professionals informed about the condition of their patients. A systematic review of surveys (Garritty & El Emam 2006) demonstrated that a PDA was more likely to be accepted and used among those physicians and residents who were younger and those who were working in large and hospital-based practices. Although PDAs could not store or organize large graphics and patients’ entire medical records, they have played a significant role in managing certain amount of electronic documentation and accessing it at the point of care easily. However to inform the development and use of mobile technologies such as smartphones and tablets, more studies with high quality design investigating the effectiveness and efficiency of using mobile technologies for specific tasks are needed.

The literature suggests that use of mobile technologies saves clinicians time on information access and retrieval and allows them to spend more time in patient care (Rothschild et al. 2002, Flannigan & McAloon 2011). This mobile technology can help healthcare professionals to enhance patient care by improving information management, supporting evidence-based decision making and accessing patient data remotely (Carroll & Christakis 2004, Garrett & Klein 2008, Stroud et al. 2009). A review (Lindquist et al. 2008) including 48 articles on the usage of PDAs among healthcare personnel and students showed that PDAs were used in patient care with varied frequency. The immediate access to drug and medical information potentially improves patient care. However, there is no robust evidence as most studies included in Lindquist et al.s review are descriptive and only six randomized controlled trials. The review suggested that the PDA appeared to be a useful tool for health care personnel and students. There is a need for more intervention studies, action research and studies with different healthcare professionals to further identify the appropriate functions and applications of the PDA.

Mobile technology adoption in health care and its barriers

Numerous studies have demonstrated cons iderable advantages of mobile technologies including wireless connectivity and therefore, a widespread adoption of this technology in health care (Franko & Tirrell 2012). A recent survey found a higher adoption rate of mobile technologies among physicians than general consumers. Lu et al. (2005) showed that more nurses in the USA and Canada were using PDAs than physicians in 2003. Previous reports proposed that over 70% of all medical residents was now operating a PDA for daily clinical support, with a 60% increase rate of use since 2001 (Barrett et al. 2004). In 2004, a survey of pharmacists found that 26% were using handheld computers on a daily basis, another example of early adopters in health care (Balen & Jewesson 2004).

Although there is evidence that mobile technologies in medicine, are used widely, several barriers to a more general adoption are evident which could discourage full use. These include personal factors (such as age, ability to comfortably use technology and devices and knowledge and skills), usability barriers (e.g. screen size), maintenance and security concerns, lack of technical support and insufficient training. It is recognized that many healthcare professionals need to be made aware of the variety of potential uses for mobile technologies. A scheduler alarm system can be set up to remind forthcoming appointments or meetings. Address books and to-do lists can help organize and synchronize departmental tasks. Document readers are important software applications, which enable healthcare professionals to view any documents in text files such as medical references (George et al. 2010).

Concerns have been raised about patient confidentiality during use of handheld devices. Password is considered as the most commonly used approach to protecting patient data (Bogossian et al. 2009). Another important factor that may affect the adoption of mobile technologies into the medical setting is cost due to the expense of handheld units themselves, the software, the network and support. It may be assumed that cost will be returned through decreasing charting time, errors reduction and more time left for patient care (Eley et al. 2008). However, there is very limited evidence of cost-effectiveness before and after adoption of mobile technologies. In addition, concerns about cross-infection between patients could also be a barrier to uptake of a mobile device for intimate patient activities in healthcare setting, which has not been addressed in the studies included in this review (Brady et al. 2012, Mather et al. 2014, Trived et al. 2011).

Larkin reported that the physician was more likely to use the PDA if it could fit into his or her workflow seamlessly or if it did not require extra effort (Larkin 2001). Undoubtedly, advances in technology overcome some of the barriers to adoption such as advancements in memory storage, battery life, larger screens, wireless capabilities and high resolution displays. Other barriers may be eliminated by providing technical and financial support for the devices and software applications and increasing necessary training programmes for the clinicians (Dongsong & Adipat 2005).

Methodological strength and limitations

The level of use of mobile technologies is expected to rise rapidly in healthcare providers’ practice. Currently, there has been limited evaluation of their use and incorporation into healthcare professionals’ educational programmes and its impact on learning outcomes. A comprehensive search strategy, rigorous selection criteria and systematic data extraction and critical quality assessment were applied to the whole review process. Since our search ended in 2012, the literature in this area has moved on. We believe, however, that our review, which rests on reproducible methods, provides a useful evidence base on the impact of mobile technologies in health practice and education. The review has demonstrated the important roles of mobile technologies in healthcare education and clinical practice settings and educators and healthcare professionals should be made aware of the potential benefits and the increasing trend of adopting mobile technologies to support and improve learning and clinical practice. Majority of the evidence reviewed is focusing on PDAs but not smartphones and tablet devices. The development of further devices opens the door to further implementation and evaluation.

This review has several limitations. Eligible studies might have been missed, although a thorough electronic and hand search was conducted. One possible explanation could be due to inconsistent terminology used in this field of research. There was also no attempt to search for unpublished studies and studies published in non-English languages. In addition, studies which only focused on usage, usefulness, accessibility, acceptance of mobile technologies or the use of an element in PDA (such as an electronic barcode system in PDA and PDA-based e-portfolio) were excluded. It is acknowledged that the inclusion of those studies may provide further insight in the review.

Most studies in this review are descriptive, with weak study designs. Studies used a variety of outcome measures making it difficult to synthesize the findings. The fact that transfer of learning (level 3 outcomes) and dissemination and value to the organization (level 4 outcomes) were not measured in any included studies provided no evidence on the effect of these training programmes in behavioural changes and increased productivity and profit. The other major limitation is that the included studies relied on self-reporting of learning rather than using assessment marks.

Conclusion

The synthesis of the evidence on the impact of mobile technologies on education and clinical practice outcomes remains inconclusive due to the descriptive nature of the body of research available to date on this topic. The development of mobile technologies for healthcare professionals is expanding rapidly and benefits of mobile technologies in the education and practice of healthcare professionals have been articulated in the literature. This review suggested that mobile technologies in healthcare potentially improve access to information, enhance productivity and quality of care, reduce medical errors, increase engagement with learning in different contexts and promote evidence-based decision making at the point of care.

Recommendations for health care and research

These considerable benefits made a significant contribution to the increased trend in healthcare professionals’ adoption of mobile technologies. Although the increasing implementation of this technology appears impressive, limited evidence about the effect of mobile technologies on patient outcomes was identified through a comprehensive literature search. The topic is still under development and is in need of further research with robust design to evaluate the effectiveness and/or cost-effectiveness of mobile technologies for enhancing care efficiency and patient outcomes and to explore expanding roles of mobile technologies and experiences of using new mobile technologies in improving healthcare education and practice among healthcare professionals and healthcare students.
