Abstract
Introduction
Inadequate knowledge and training of healthcare providers are obstacles to effective chronic pain management. ECHO (extension for community healthcare outcomes) uses case-based learning and videoconferencing to connect specialists with providers in underserved areas. ECHO aims to increase capacity in managing complex cases in areas with poor access to specialists.
Methods
A pre-post study was conducted to evaluate the impact of ECHO on healthcare providers’ self-efficacy, knowledge and satisfaction. Type of profession, presenting a case, and number of sessions attended were examined as potential factors that may influence the outcomes
Results
From June 2014 to March 2017, 296 primary care healthcare providers attended ECHO, 264 were eligible for the study, 170 (64%) completed the pre-ECHO questionnaire and 119 completed post-ECHO questionnaires. Participants were physicians (34%), nurse practitioners (21%), pharmacists (13%) and allied health professionals (32%). Participants attended a mean of 15 ± 9.19 sessions. There was a significant increase in self-efficacy (p < 0.0001) and knowledge (p < 0.0001). Self-efficacy improvement was significantly higher among physicians, physician assistants and nurse practitioners than the non-prescribers group (p = 0.03). On average, 96% of participants were satisfied with ECHO. Satisfaction was higher among those who presented cases and attended more sessions.
Discussion
This study shows that ECHO improved providers’ self-efficacy and knowledge. We evaluated outcomes from a multidisciplinary group of providers practicing in Ontario. This diversity supports the generalisability of our findings. Therefore, we suggest that this project may be used as a template for creating other educational programs on other medical topics.

Introduction
Chronic pain (CP) affects 20% to 30% of the adult population.1–3 Worldwide, CP is among the top chronic conditions that contribute to years lived with distress and disability. 4 Compared with people who live close to academic hospitals in urban areas, CP patients who live in rural areas often suffer from higher pain levels and more severe functional impairments, which are most likely mediated by depression and low quality of life.5–7 In Canada, healthcare providers (HCPs) manage around two-thirds of CP patients in primary care settings, with little or no training in managing this condition.8,9
Of particular concern in pain management is the dramatic increase in the rates of opioid prescriptions and the parallel rise of prescription opioid overdose, abuse and diversion.7,10,11 Most opioid prescriptions are written by primary care clinicians who have received minimal training in safe opioid prescribing.12,13
Project ECHO (extension for community healthcare outcomes) is a collaborative model of tele-education and care management that empowers participating clinicians to provide expert level care in their own communities. The first ECHO for CP started in New Mexico (USA) and it has consistently demonstrated improvements in self-reported knowledge, skills and advanced practice.14,15 The replication of ECHO pain in the US Veterans Health Administration showed that participation in ECHO was associated with increased utilisation of physical medicine services and initiation of nonopioid medications among patients with chronic pain. 16 The ECHO model™ does not ‘deliver’ specialist care directly to patients; instead, it increases access to specialist skills by providing primary care clinicians with the knowledge and support they need to manage patients living in rural or otherwise underserved areas. Evidence for the effectiveness of the ECHO model has been demonstrated in conditions such as hepatitis C, chronic pain and addiction.17–19
In response to the difficulties faced by HCPs in managing patients with CP plus the opioid crisis in Ontario, the Ministry of Health and Long Term Care (MOHLTC) funded the first replication of the ECHO model in Canada: ECHO Ontario Chronic Pain/Opioid Stewardship; as of April 2017, this programme has received permanent funding from the MOHLTC. 20
The objectives of this study are to: (a) describe the impact of ECHO on clinicians’ self-efficacy and knowledge related to CP management and opioid prescribing; (b) evaluate acceptability and the impact of participation in ECHO on participant’s practices; and (c) assess if the results are modified by participant’s profession, number of sessions attended or presenting a case in ECHO.
Methods
Intervention
ECHO Ontario Chronic Pain/Opioid Stewardship includes an interprofessional group of CP experts, the ‘hub’. The hub connects with multiple primary healthcare providers, the ‘spokes’, in Ontario using videoconference once a week. The hub team includes physicians (pain medicine, addiction, family medicine, neurology, physiatry and psychiatry) as well as a psychologist, nurse, social worker, physical therapist, occupational therapist, pharmacist, chiropractor and medical librarian, along with a telemedicine technician. ECHO runs weekly 2-hour sessions that comprise a 20–30 min didactic on a relevant topic given by a Hub member, or invited speaker as well as discussion of actual cases presented by a participating spokes. The de-identified patient case presentation follows a standard format. The spokes can attend as many sessions as they want, and they inform the coordinator when they will exit the programme.
Between June 2014 and March 2017, ECHO delivered a total of 124 didactic lectures in six curriculum cycles and four in-person weekend workshops. Participants received 6004 h of no-cost medical education and claimed 3433 h of continued medical education (CME) credits. (Not all attendees required or requested CME credits). Participation in ECHO is cost free for HCPs because the project is permanently funded by the Ontario MOHLTC.
Study design
A pre-post online survey was used to evaluate the impact of ECHO in Ontario, Canada. The post-ECHO survey was sent by email when the subjects informed they were exiting the programme. The pre and post surveys were linked within subjects.
Participants and procedure
HCPs from across Ontario were recruited for participation in ECHO. Participants provided informed consent while completing the online questionnaire. The study was approved by the Research Ethics Board at the University Health Network (#14-7415).
Respondents were recruited to ECHO between June 2014 and March 2017. Participant eligibility included practicing in Ontario, the ability to speak and read English, and attendance of at least one ECHO session. We excluded participants who were still attending ECHO at the time of the study closure.
Measures
Participant demographics
We compiled information about participants’ age, gender, years in practice, profession and number of CP patients seen per week. Given the varied clinical backgrounds, we grouped attendees as those who can make decisions about opioid prescribing including physicians, physician assistants (PA) and nurse practitioners (NP); those who do not prescribe opioids but work closely with opioid prescribers: pharmacists and registered nurses (RN), and other allied health professionals such as psychologists, physiotherapists, occupational therapists, chiropractors and social workers.
We recorded the number of sessions each participant attended and whether or not they had presented a case during an ECHO session.
Outcome measures
Self-efficacy
We used a 19-item self-efficacy scale initially developed to assess the first ECHO Hepatitis C programme in New Mexico on a seven-point Likert scale ranging from 1 = ‘none or no skill’, to 7 = ‘expert, able to teach others’. 17 We adapted the questions to assess participant’s confidence in CP management and opioid prescribing (See supplementary Appendix 1).
Knowledge
We assessed knowledge via eight items adapted from the KnowPain-12. 21 Knowpain-12 is a newly developed tool aiming to assess provider’s pain management knowledge/attitude/behaviour. Since we were aiming to assess knowledge, we only selected the items that assess knowledge from Knowpain-12 and excluded others that are related to attitudes and behaviours. We also excluded one question that is specific to the United States healthcare system (See supplementary Appendix 1). Total scores could range from 0 to 16. After selecting the knowledge items, a pilot study was conducted to assess whether all the items were appropriate for non-physician participants or not. However, many of the non-physician participants expressed concerns that the knowledge test was supposed to be answered only by physicians and irrelevant to their field of practice. Many of the non-physician participants were leaving these questions blank. Therefore, the response options were also changed from the original version. The response options included ‘true’, ‘false’, ‘don’t know’ or ‘not applicable to my practice’.
Acceptability and impact of participation in ECHO
We used a self-report validated 11-item questionnaire developed by Arora et al. to measure acceptability and impact of ECHO. 17 This questionnaire includes statements that assess value of participation, achievements of learning goals, professional satisfaction and isolation, subjective impression of quality of care, sense of participation in a community of practice, and perceptions of practice changes and variations in care. We rated each statement using a six-point Likert scale ranging from 1 = ‘Strongly Disagree’ to 5 = ‘Strongly Agree’, with 6 representing ‘Not Applicable’ (See supplementary Appendix 1).
Data analyses
Data analyses were performed using the latest version of Statistical Package for Social Sciences (SPSS 23.0). Demographic questionnaire response data were summarised using descriptive analyses (i.e. mean ± SD, range, percentage) to characterise the sample and variables of interest.
We examined differences between the study participants and dropouts via t-tests for the continuous variables (sessions attended, self-efficacy), and chi-square analyses and Fisher’s exact tests, for the binary and categorical variables (profession type and case presentation). Few missing data points were observed on individual items (less than 20% missing on individual items for each scale). These missing values were replaced using case mean substitution, which is considered to be a robust method of handling missing data when missingness is less than 30%.22,23
Change scores for each outcome (self-efficacy and knowledge) were computed and differences between profession types were evaluated via analysis of variance (ANOVA). Repeated measures analysis of variance was used to assess differences in each main outcomes (self-efficacy and knowledge) before and after participation in ECHO by provider status and case presentation (yes or no). Pearson product moment or Spearman’s correlation coefficients estimated the relationship between changes in outcomes and the number of sessions attended by each participant.
Acceptability and Impact of ECHO was also assessed using chi-square tests for overall sample, and summarised by profession type and by case presentation.
All tests were two-tailed and a Bonferroni correction was performed on each set of analyses to control against Type 1 error. Effect size was calculated by dividing the average mean difference by the standard deviation for paired difference. Cohen suggests effect sizes of 0.2 or less are considered small, effect sizes of 0.5 are considered medium and 0.8 are considered large. 24 Cohen’s d effect sizes were also calculated for each paired difference.
Normality was also assessed by visually inspecting q-q residual and histogram plots, as well as by examining skewness and kurtosis values associated with each outcome variable, both for overall sample and by profession type and case presentation.
Results
Over the course of the study, 296 participants enrolled in ECHO (Figure 1). This study focuses only on these 119 eligible clinicians who completed both pre- and post-ECHO questionnaires. Data indicate that dropouts were more likely to have not presented a case during ECHO, but they were similar in terms of profession, location of practice, age, sex, level of education or pre-ECHO outcome measures.

Participant characteristics
Demographics.
NP: nurse practitioner; PA: physician assistant; PT: physiotherapist; OT: occupational therapist; SW: social worker; CP: chronic pain.
Participants attended an average of 15 ± 9.19 2-h sessions (range 2–53). Sixty-six clinicians presented 196 cases: 164 new cases and 32 follow-ups. The most common pain diagnoses included low back pain, migraine headaches, neck pain, fibromyalgia, myofascial pain syndromes and neuropathies.
Self-efficacy
Of the 111 participants who responded to the self-efficacy pre- and post-ECHO questionnaires, 63 (58%) were Physicians/PA/NPs, 21 (19%) RN/Pharmacists and 25 (23%) allied health professionals.
We found increased confidence in pain management from pre- to post-testing, both for individual items and for the overall self-efficacy score. The total effect size for self-efficacy pre- to post-ECHO was 0.95, which is considered large.
Significant main effects for prescriber status (F(1, 111) = 50.842, p = .000, η2 = .31) and time (F(1, 111) = 43.6, p = .000, η2 = .51) were found suggesting that, on average, prescribers reported greater self-efficacy than non-prescribers and that self-efficacy scores increased significantly from pre- to post-ECHO (Figure 2).

Further, a significant interaction effect was observed demonstrating that self-efficacy scores increased differently from pre to post-ECHO depending on prescriber status, F(1, 111) = 14.768, p = .000, η2 = .12. Although simple main effects demonstrate that non-prescribers self-efficacy scores significantly increased from pre- to post-ECHO programme (p < .001), prescribers reported significantly greater self-efficacy on average following the ECHO programme than non-prescribers (F(1, 111) = 24.92, p = .000, η2 = .18 (Figure 2).
No differences in self-efficacy between case-presenters and non-case-presenters were found after adjusting for type 1 error (F(1, 111) = 5.36, p = .022, η2 = .046). There was no significant relationship between overall self-efficacy change and number of sessions attended (r = .175, p = .066).
Knowledge
A total of 105 participants responded to the knowledge section pre- and post-ECHO. Knowledge significantly increased for all ECHO participants, t(104) = −8.58, p = .000, d = .84.
Significant main effects for prescriber status (F(1, 104) = 15.32, p = .000, η2 = .12) and time (F(1, 104) = 160.193, p = .000, η2 = .58) were found, suggesting that prescribers had greater knowledge on average compared with non-prescribers and that knowledge increased post-ECHO programme. No significant interaction between prescriber status and time was observed, F(1, 104) = .272, p = .603, η2 = .002 (Figure 3).
Knowledge scores pre and post-ECHO by profession (prescribers: physicians, NPs and PAs; non-prescribers: all other professions).
Attending ECHO led to a significant increase in average knowledge scores in both case presenters and non-presenters, F(1, 104) = −105.95, p = .000, η2 = .41). The increase in knowledge from the programme was similar between presenters and non-presenters, F(1, 104) = .016, p = .899, η2 = .00), and no significant interaction between case presentation and time was demonstrated, F(1, 104) = .456, p = .501, η2 = .004).
There was no significant relationship between knowledge change and number of sessions attended, correlation coefficient, rs = .08, p = .407, or t-tests stratified by number of sessions attended (21 or more sessions), t(103) = −.381, p = .704, d = 0.09.
Acceptability and impact of participation in ECHO
Of the 117 participants who responded to the acceptability and impact section post-ECHO, the majority agreed or strongly agreed with the 11 impact statements (Figure 4); 96% of participants said they would recommend ECHO to any of their colleagues.
Percentages of participants who selected agree/ strongly agree on the 11-item impact and acceptability scale.
Acceptability levels were equivalent between professions (ps = .130 −.888). There was a significant positive relationship between number of sessions attended and three items (p-values ranged from .000 to .005).
Participants who presented a case in session were more likely to strongly agree with 3 of the 11 acceptability and impact items compared with participants who did not present a case (p-values ranged from .000 to .004).
Discussion
We evaluated the first 2.5 years of its implementation and assessed the impact of ECHO on participants’ self-efficacy, knowledge regarding CP management and opioid prescribing, along with participants’ acceptability and impact after attending ECHO.
Self-efficacy is a construct described by Albert Bandura,25,26 and is defined as the individual’s belief in their capacity to execute a behaviour necessary to produce a specific action. It reflects the person’s ability to control their own motivation, behaviour and social environment. Gaining self-efficacy is the first step towards behaviour change.27,28 Our findings demonstrated a significant increase in self-efficacy after attending ECHO. All professions improved their self-efficacy, but the groups of physicians, PAs and NPs had the highest gain in self – efficacy compared with other professions. These findings were expected since most of the didactic sessions and case presentations involve some sort of pharmacological treatment. Professionals who are not directly involved in medication management may not perceive their improvements the same as the professionals who are involved with medications more often.
Our results also showed that ECHO significantly improved participants' knowledge regarding CP assessment, treatment practices and opioid prescribing. Our results suggest that the ECHO intervention successfully enhanced provider knowledge of pain management regardless of profession. The ECHO model applies adult learning theory when participants present cases from their own practices, so new teaching and learning are applied at the right time and the right place. The recommendations on each case presented are discussed in an informal discussion by the whole group, where all teach and all learn. These improvements in clinician’s knowledge are consistent with other ECHO replications in other health conditions such as mental health, 29 and hepatitis C. 30
Our attendees were highly satisfied with ECHO and felt that their participation had an impact in improving the care they offer to their clients with chronic pain. Participation in ECHO was a worthwhile experience that enhanced their professional satisfaction and reduced isolation. Though no differences were found in acceptability levels between different professions groups, participants who presented a case were more satisfied than those who did not present cases. Weekly case-based learning is a critical component of the ECHO model and is an effective method in continuing medical education pedagogy.17,31,32
Our attendees also reported that attending ECHO impacted their practices to a great extent. The majority reported that attending ECHO improved the quality and safety of patient care for CP and has reduced variation in care and, most importantly, has expanded access to effective CP treatments in their community. 33
Our findings are consistent with others who have demonstrated that clinicians’ self-efficacy and knowledge can be improved by ECHO.14,34 A recent systematic review by Zhou and colleagues found that ECHO is an effective and potentially cost-saving model that increased clinicians’ self-efficacy, confidence, changed their attitudes and improved their knowledge with subsequent improvements in patients’ outcomes. This was especially true for HCPs who are working in isolated rural locations. 35 This longitudinal learning process may promote direct uptake in practice since the clinicians often return to clinical activities shortly after the completion of each weekly session.
Our study’s strength is a pre-post intervention study design where subjects served as their own controls. We evaluated HCPs’ outcomes from a multidisciplinary group of clinicians practicing in Ontario. This diversity helps with the generalisability of our findings. In addition, we were able to recruit and retain many opioid prescribers to attend ECHO, and it seems that this group was the one that gained most from their participation in ECHO.
Despite our efforts to ensure rigour and reduce bias, one limitation of this study is that the pre-test may sensitise participants to the intervention and change the way that they respond to the post-test. 36 Moreover, some may argue that all our outcome measures are self-reported and purely subjective measures leaving many unanswered questions, such as: how ECHO works in reducing professional isolation, improving joy of work and patients’ outcomes. Nevertheless, although several studies assessing the impact of ECHO have shown a positive correlation between self-reported changes and patients outcomes or changes in attendees’ practices, we are still aware of this limitation. Therefore, we are currently conducting other studies using objective measures. Ongoing research include mixed methods such as qualitative interviews with clinicians and patients, and quantitative methods to assess practice changes that would reflect patients’ receiving appropriate investigations, education, treatment and management of their CP by their primary care providers. We think it is important to also demonstrate if ECHO has the capability to reduce wait lists to specialist care, and reduce variation and costs of health care.
Conclusions
The ECHO model developed at the University of New Mexico was successfully implemented in Ontario to address a knowledge and practice gap in CP management and opioid prescribing. Participation in ECHO was associated with significant improvement in self-efficacy and knowledge about CP for all participants, but it was more pronounced in participants who can prescribe opioids than allied professionals who do not prescribe medications. Participants who present cases during ECHO sessions are more satisfied with ECHO than those who only attend and do not present cases. On average participants attended 30 h (range 4–106 h) of ECHO sessions, but improvements were not dose dependent.
