Barriers to evidence-based physiotherapy practice for stroke survivors in Ghana.

BACKGROUND: Physiotherapy has evolved over the years, and this has led to an increasing demand in using evidence as a basis for making clinical decisions because evidence-based interventions for stroke have been shown to be effective. However, the inability to carry out any of the evidence-based practice (EBP) processes may constitute a barrier to its application in practice. AIM: To determine the barriers to EBP of physiotherapy services for stroke survivors in Ghana.
METHODS: A cross-sectional study that involved 121 physiotherapists of the Ghana Physiotherapy Association providing services to stroke survivors. Physiotherapists completed a self-administered questionnaire. Logistic regressions were used to examine relationships between socio-demographic and practice characteristics of respondents and each practitioner factor. A logistic regression was used to identify the association between organisational characteristics and each organisational factor that facilitates EBP.
RESULTS: Self-efficacy ratings for performing EBP were below 50% for critical appraisal of the literature and interpretation of statistics. All the participants stated that they had organisational challenges, which tend to affect the implementation of evidence-based physiotherapy practice for stroke. The five most reported barriers to updating knowledge on EBP included lack of organisational mandate (56.2%), insufficient time (46.3%), lack of information resources (43%), lack of understanding of statistics (35.5%) and lack of interest (33.1%).
CONCLUSION: Lack of adequate resources, lack of organisational support and low self-efficacy to perform EBP activities constitute barriers to implementing EBP for stroke survivors. CLINICAL IMPLICATIONS: Findings of the study reinforce the need to develop a supportive organisational infrastructure to increase research integration in physiotherapy practice.

Introduction

Evidence-based practice (EBP) is a five-step process through which clinicians integrate research evidence with clinical expertise and patient preferences, producing the most appropriate and effective service (Bello 2011). It includes expressing questions that arise from clinical practice in a searchable format; effectively finding the best evidence to address the question, a step that may require an online literature search; and critically appraising the evidence for validity, impact and applicability to the clinical question (Silva, Costa and Costa 2015). The inability to carry out any of these functions may constitute a barrier to the application of EBP in practice. The Sicily statement in 2005 recommended that every individual practitioner be trained in the five-step model of EBP with skills to ask a research question, access, appraise and apply the evidence, and assess the process (Dawes et al. 2005). However, in Ghana, this has not been categorically embedded in the curriculum of the entry-level education (bachelor’s degree). Hence, physiotherapy undergraduate students access EBP training on their own, either via journals or via online access. A systematic review of studies conducted over the world, describing current evidence of EBP by physiotherapists (PTs), showed that the most frequent barriers reported were lack of time, inability to understand statistics, lack of support from employer, lack of resources, lack of interest and lack of generalisation of results (Mota da Silva, Costa & Garcia 2015). Engaging with both research and clinical findings can enhance the proficiency of PTs’ clinical practice (Bello 2011) and help prevent the misuse, overuse and underuse of health care service (Kumar, Grimmer-Sommers & Hughes 2010).

Over the years, several studies have shown that EBP improves the effectiveness of health service delivery and, consequently, client outcomes. Evidence supporting this finding for stroke has been reported (Langhorne, Bernhardht & Kwakkel 2011). However, even when an intervention has good evidence of benefit, the application of EBP for stroke can still raise challenges (Burt, Lohn & Cohe 2009). For example, a systematic review by Scurlock-Evans and colleagues comprising 32 studies from Europe, Africa and Asia showed that the main barriers faced by PTs were usually related to lack of time and skills, and also misperceptions of EBP. Other considerable barriers related to the workplace include no access to scientific literature at work, no policies at work to stimulate the use of evidence, lack of training at work to use the evidence (Gorgon et al. 2013) (study in Philippines) and an inability to make changes in the workplace (Iles & Davidson 2006) (study in Australia).

Manns, Norton and Darrah (2015) show that the content of EBP, knowledge and skills in physiotherapy have been improved over the years, both in education curricula and in clinical practice, but research evidence is used minimally, and thus the gap between knowledge and practice continues. The assumption was that this knowledge set would result in the increased use of EBP behaviours by graduates. However, both the medical (Flores-Mateo & Agimon 2007) and rehabilitation (McEvoy et al. 2011) literature conducted in Australia suggest that a knowledge-to-practice gap exists, with a lack of uptake of EBP skills into clinical decision-making. Studies on barriers to EBP have been carried out among PTs in the United States (Jette et al. 2003), United Kingdom (Pollock et al. 2014) and Canada (Salbach et al. 2007). Similar barriers to EBP were reported in these countries, which included lack of time, misperceptions of EBP and lack of understanding of statistical analysis. However, differences in entry-level training, health care systems and professional practice across countries limit the generalisability of those studies to the Ghanaian environment.

There is evidence to support stroke rehabilitation in well-coordinated multidisciplinary stroke units or through provisions of early supported provision of discharge teams (Langhorne et al. 2011). Potentially, beneficial treatment options for motor recovery of the arm include constraint-induced movement therapy (CIMT) and robotics (Langhorne et al. 2011). In addition, the integration of electrical stimulation and physiotherapy is feasible and tends to improve gait post-stroke (Wilkinson et al. 2015). Teasell et al. (2015) in a study of evidence-based stroke rehabilitation showed that there is a high level of evidence for stroke rehabilitation. However, by anecdotal observations during clinical rotations, the use of research findings in clinical practice is not very common among PTs in Ghana. There also seems to be a dearth of information on barriers to evidence-based physiotherapy (EBPT) practice in Africa. Thus, the primary objective of this study was to determine the barriers to the implementation of EBP by PTs for stroke survivors in Ghana. A secondary objective was to identify associations between organisational characteristics and each organisational factor to facilitate EBP.

Methods

A cross-sectional survey of PTs who are providing or have provided services to people with stroke in Ghana was conducted. All 130 members of the Ghana Physiotherapy Association (GPA) were recruited for the study using a convenience sampling technique. The study was conducted in both private and public physiotherapy facilities in Ghana. PTs were considered eligible for the study if they had two or more years of working experience and were registered members of GPA. Physiotherapists who were not registered members of GPA, had less than 2 years working experience and had not treated people with stroke before were ineligible for the study.

Data collection tool

The ‘barriers to evidence-based physical therapy practice for people with stroke’ questionnaire used by Salbach et al. (2007) was the instrument adapted for this study. The instrument was a one-time questionnaire that included 40 items of which the majority required participants to indicate their level of agreement with a statement on a 5-point Likert scale. Those recipients who indicated in the first item that they did not provide services to people with stroke were excluded and were asked to leave the rest of the questionnaire blank. Questionnaire items (Appendix 1) were designed to identify practitioner and organisational factors influencing EBP. Subgroups of items were used to evaluate education about EBP (items 13–15), attitudes and beliefs (items 2, 3, 5 and 7), interest (items 4 and 6) and perceived role (items 11 and 12) to engage in EBP, self-efficacy to perform EBP activities (items 16.1–16.12), perceived organisational and peer support for EBP (items 23 and 24), and organisational resources and support to promote EBP (items 17–22). One item was used to identify the three greatest barriers to updating clinical practice with new knowledge (item 25). Items were added to the end of the questionnaire to evaluate respondent demographics, practice characteristics and work setting (items 26–40). The questionnaire was developed by pooling the primary source of items from a survey tool used by Jette et al. (2003) to evaluate PTs’ beliefs, attitudes, knowledge and behaviour in relation to EBP. Items were added to assess EBP beliefs and the existence of an organisational mandate supporting EBP. Three new items to evaluate physical therapists’ perceived role in searching and appraising the research literature and interpreting its applicability to individual clients were devised based on investigations by other researchers.

Self-efficacy to perform EBP activities (items 16.1–16.12) was measured using a 12-item scale that was developed in adherence to guidelines for developing self-efficacy scales. Participants were asked to rate their level of confidence in their ability to perform each activity, using an 11-point scale ranging from 0% (‘cannot do at all’) to 100% (‘certain can do’).

Procedure

Potential participants were asked to indicate in the first item of the questionnaire whether they provide or have provided services to stroke survivors or not. Follow-ups were made via phone calls, e-mails and text messages twice every week to serve as reminders because most participants complained of busy schedules at their workplaces. Participants in other regions were required to submit the questionnaire within 4 weeks to a research assistant who in turn returned them personally or by post to the first author. Participants who received the questionnaire by e-mail submitted via the same channel and the questionnaires were then printed out. Copies of questionnaires were retrieved personally from some participants. Of the 130 registered PTs contacted, 121 responded, representing a 93% response rate.

The data were analysed using the Statistical Package for Social Scientists (SPSS), version 23, to run basic descriptive statistics such as frequencies, percentages and means of the main variables of investigation. The prevalence of practitioner and organisational factors was estimated using percentages. A logistic regression was used to examine relationships between socio-demographic and practice characteristics of respondents (i.e. independent variables) and each practitioner factor (i.e. dependent variable). Independent variables included age, sex, highest degree obtained, number of years practising, number of hours worked per week, number of patients seen per day, care delivery within a multidisciplinary team (MDT) and supervision of physiotherapist students. Dependent variables were items used to determine education about EBP, attitudes and beliefs, interest and perceived role in EBP, and self-efficacy to perform EBP activities.

A logistic regression was also used to identify associations between organisational characteristics (independent variables), including facility location and type, number of physical therapists at the facility, and status as a teaching institution, and each organisational factor (dependent variable), including items measuring perceived peer and organisational support and the existence of resources (e.g. access to journals, Internet and personnel) to facilitate EBP.

In order to use a logistic regression, categories were combined to produce binary-dependent variables. For instance, for statements with a positive response set using a Likert scale, the ‘strongly agree’ and ‘agree’ categories were collapsed to form an ‘agree’ category, and the ‘neutral’, ‘disagree’ and ‘strongly disagree’ categories were combined to form a ‘disagree’ category. For items with a negative response set, the ‘strongly disagree’ and ‘disagree’ categories were collapsed to form a ‘disagree’ category, and the ‘neutral’, ‘agree’ and ‘strongly agree’ categories were combined to form an ‘agree’ category. Categories of demographic variables with low cell counts also were collapsed in order to obtain stable estimates in the regression analyses. A logistic regression was then performed to estimate the influence of each independent variable on a dependent variable. Odds ratios (ORs) and associated 95% confidence intervals (CIs) were reported for statistically significant associations. The alpha level was set at p = 0.05.

Ethical consideration

Ethical approval (SBAHS/10403342/AA/R4/2015-2016) was obtained from the Ethics and Protocol Review Committee of the School of Biomedical and Allied Health Sciences, University of Ghana.

Results

The final sample consisted of 74 males (61.2%) and 47 females (38.8%) between 20 and 40 years of age (mean = 30 ±6). A bachelor’s degree (91.7%) was the most commonly cited highest degree obtained and 68 (56.2%) of the respondents reported having between 5 and 8 years of practice experience.

Table 2 shows characteristics of the organisations for which the participants worked. The most frequently reported characteristics were an urban location among 107 (88.4%) of the participants. One hundred and three (88.5%) participants worked in a general hospital and 70 (57.9%) participants practised in a teaching hospital. Table 3 shows participants’ educational background, attitudes and beliefs towards EBP and their interests and perceived roles in EBPT. Mostly, 118 (97.5%) participants generally held positive attitudes and beliefs about EBP. Eighty (66.1%) participants disagreed that the adoption of EBP creates unreasonable demands on PTs and 84 (69.4%) participants disagreed that EBP does not take into account patient preferences. The participants were diverse in expressing whether or not they had the knowledge and skills necessary for EBP or in search engines. More than half of the participants, 82 (67.8%), had learned the foundations for EBP as part of their academic preparation and about 81 (66.9%) agreed that they had received formal training in search engines in finding research relevant to their practice.

Average self-efficacy ratings were between 50% and 70%, for critically appraising the literature for reliability and relevance, the psychometric properties of outcome measures and the strengths and weaknesses of different study designs. Average ratings below 50% were observed for participants’ confidence about their ability to interpret results of statistical procedures such as t-tests, chi-square tests and linear or logistic regression. Self-efficacy ratings for 12 different activities necessary to implement EBP are shown in Figure 1.

Figure 2 shows the distribution of response related to organisational factors affecting the implementation of EBPT for stroke survivors. All the participants stated that they generally had organisational challenges, which in turn affected the implementation of EBPT practice for stroke. Most (113; 93.4%) of the participants stated that their facilities did not provide protected time to conduct literature reviews and appraise the literature, and 108 (89.3%) of the participants did not have access to current research. One hundred (82.6%) participants stated that their facilities do not mandate the use of current research findings in practice.

It was noticed that age, highest degree attained and number of years practised by participants were associated with academic preparation in EBP and formal training with critical appraisal. Sex was also associated with training in critical appraisal skills with male participants 3.0 times more likely than female participants to report training (95% CI = 0.5–2.1). Age, years practised, hours of work per week and practice in a multidisciplinary team were each associated with formal training with search strategies. For example, compared with participants who had more than 8 years of practice experience, participants with less than 5 years of experience were 18.3 times more likely to have learned the foundations of EBP in their academic preparation (95% CI = 1.8–2.9) and 8.5 times more likely to report having received formal training in critical appraisal skills (95% CI = 5.6–132.7). The relationships between socio-demographic and practice characteristics and EBPT practice are presented in Table 4.

Location and type of facility, the number of full-time PTs and status as a teaching institution were associated with perceived organisational resources to support EBP. Compared with urban settings, organisations in rural settings were likely to provide journals in paper format, Internet access or a resource person to assist EBP. Physiotherapists working in a teaching institution were 5.0 times more likely than participants working in a non-teaching institution to report receiving financial support. Table 5 shows the relationship between organisational characteristics and each organisational factor.

Discussion

Physiotherapists in this study held positive attitudes and beliefs about EBP as also indicated in previous studies by Salbach et al. (2007); Scurlock-Evans, Upton and Upton (2014); and Mota da Silva et al. (2015). This was observed despite differences in the practice settings, which varied across studies such as rehabilitation settings (Mota da Silva et al. 2015), acute care hospital setting (Salbach et al. 2007) and general hospital setting (as in our study). A higher educational qualification was positively associated with knowledge and skills of EBP in this study as also reported by Scurlock-Evans, Upton and Upton (2014). Contrary to the findings made by Jette et al. (2003), participants (PTs) of this study rated their confidence in research as very low, likewise critical appraisal of psychometrics and statistics. The differences in the self-efficacy ratings of PTs in relation to research and literature appraisal could be that most PTs in this study may not have acquired further knowledge in critical appraisal of research literature because continuous professional development programmes organised or attended in Ghana to date may not have fully addressed this topic. It is also possible that the lack of time and busy schedules at the various facilities may have caused this low confidence.

It is important to note that more than half of the participants stated that they have received formal training in critical appraisal of the literature; however, they reported low self-efficacy ratings in critically appraising the psychometric properties of outcome measures (20%), critically appraising the strengths and weaknesses of different study designs (19%) and interpreting results of statistical procedures such as t-tests and chi-square tests (18%) and linear or logistic regression (16%). The concern, according to the self-efficacy theory, is that PTs with low self-efficacy for searching and appraising research literature and integrating the findings into clinical practice are less likely to perform these activities than people who perceive their level of skill to be higher (Shea, Basch & Zybert 2008).

In this study, PTs who have practised for less than 5 years demonstrated better knowledge and skills of EBP compared with PTs with more than 8 years of practice. A study conducted by Manns et al. (2015) in Alberta, Canada, revealed similar results. A lower percentage of participants (PTs) perceived their organisation or facility to be supportive of using current research in practice; however, this support was not in the form of a mandate promoting research use. This outcome suggests that physiotherapy facilities or organisations in Ghana do not provide support for the implementation of EBP, especially in rural areas. The failure of facilities to make provision of such resources as stated by the participants in our study may be responsible for their low level in implementing EBP for stroke survivors. Bozzolan et al. (2014) reported similar results where the shortage of resources available in the workplace presented limitations in the implementation of EBP among health professionals in Italy. Overall, there is a need to develop a supportive organisational infrastructure in addition to enhancing skills of the evidence-based practitioner to increase research integration in physiotheraphy practice for stroke survivors (Rappolt et al. 2005).

This study’s findings highlighted potential practitioner and organisational barriers to the implementation of EBPT for stroke survivors with organisational barriers being the most reported. A notable practitioner-level barrier to the implementation of EBP was the lack of formal education and training in how to critically evaluate research literature. Without protected time or the skill to conduct literature searches, PTs cannot take advantage of Internet access to online databases, which were even less available to 83.5% of the PTs who participated in this study. A consistent observation was that PTs who work in community care centres, rural or non-teaching institutions are particularly disadvantaged regarding the implementation of EBP because of a lack of educational and human resources. Salbach et al. (2007) reported similar results in a study conducted in Canada.

Most of the PTs in this study stated, in descending order, the following as the five major barriers to implementing EBPT for stroke survivors: lack of an organisational mandate, insufficient time, lack of information resources, lack of understanding of statistics and lack of interest. In contrast, the most reported barrier to EBPT for stroke survivors according to some studies was insufficient time (Panhale & Bellare 2015; Scurlock-Evans et al. 2014).

There was a limited period for data collection. There is therefore the possibility that participants may have completed the questionnaire in haste in order to meet the time limit. Some participants who were contacted personally were reluctant to participate owing to the busy nature of their work and personal schedules.

Conclusion

Lack of adequate resources, lack of organisational support and low self-efficacy to perform EBP activities represent barriers to implementing EBP for stroke survivors. This study found a positive relationship between educational qualification and knowledge and skills of EBP. In addition, the study showed that most physiotherapy facilities or organisations in Ghana were not supportive in the implementation of EBP for stroke survivors. These findings reinforce the need for continuing education to enhance skills and self-efficacy to search and critically evaluate the research literature among Ghanaian PTs.
