INTRODUCTION

When it comes to pain management, primary care clinicians (PCCs) find themselves in a somewhat unexpected role. (1) Few conditions intersect with a range of specialties (i.e., mental health, orthopedics, endocrinology, etc.), disability, and aberrant behavior in the way that chronic pain does. PCCs find themselves in a position where they are asked to assess and diagnose sometimes vague and diffuse pain, and determine appropriate treatment often before the underlying cause of the pain is well-understood. A recent cultural shift in the USA has created a situation in which a formerly default treatment, prescription opioid therapy, is no longer considered safe or appropriate for many patients with chronic pain. The addictive qualities and overall safety profile of opioid medications have come into sharp focus in recent years, leading to a push to reduce opioid use while also trying to achieve pain relief with little guidance for PCCs about how to manage this change in treatment plans. (2, 3) Others have documented the uneasiness many experience in managing patients with chronic pain (4, 5). One participant in our study described the sense that opioid prescribing sometimes extends into unexpected and disconcerting territory in this way: “I never signed up to be an enforcer.” The complexity and moral uncertainty (6) associated with managing patients with chronic pain are an important backdrop for the findings from this study.

Despite limited formal training about chronic pain (7, 8), PCCs play a critical role in supporting patients as they seek to optimize quality of life while managing the risks associated with different treatments. The current study extends prior studies highlighting the emotional burden, inadequate resources, lack of trust between patient and provider (4), and patient-provider communication challenges (5) associated with managing patients with chronic pain. Much prior research was conducted using surveys and focus groups. To extend this body of knowledge, we conducted in-depth interviews with individual PCCs in the context of the recently released CDC guidelines which prompted many institutions to adopt strict opioid prescribing guidelines. (9) Our intent was to better understand current beliefs and strategies for managing noncancer chronic pain in this new era.

METHODS

Overall Study Design

In this study, we asked PCCs to describe their general approach to managing patients with chronic pain, and then to walk us through examples of such patients so that we could understand how this general approach is applied and tailored in the context of real patients. The resulting context-rich dataset provides insights not easily obtained with surveys or observational studies. In this paper, we focus on the portions of the interviews in which PCCs shared their evolving understanding of opioid therapy, and the strategies they have developed to encourage and motivate patients.

Participants

From April 2016 to July 2018, we recruited a purposive sample of 20 PCCs who prescribe opioids and treat patients with chronic noncancer pain. Recruiting strategies included email invitations, in-person presentations at clinic staff meetings, and word-of-mouth. Participants were given a $100 gift card for each interview. Our sample included PCCs from three health systems, including one non-profit hospital system with primarily rural clinics in Indiana and Illinois; a safety net hospital serving a major urban center in Indiana; and an academic medical center with hospitals and clinics throughout Indiana in rural, urban, and suburban regions. Our initial plan was that each PCC would participate in up to 5 interviews. We analyzed transcript as they became available, determining we had reached thematic saturation (i.e., when additional data did not reveal any new themes) (10,11,12) after 89 interviews with 20 providers.

Data Collection and Analysis

The initial interview with each PCC began with questions about the PCC’s patient population; general approach to chronic noncancer pain care; and tools and instruments used when caring for patients with chronic noncancer pain. The remainder of the initial interview and all subsequent interviews with each PCC used an adapted critical decision method technique (4), focusing on a recent patient that the PCC confirmed to have a chronic noncancer musculoskeletal pain condition. A different patient was discussed in each interview session. Follow-up probes were used to explore cues, goal, strategies, and actions taken for key events in the patient’s history. Traditional critical decision method interviews focus on eliciting a challenging incident from the perspective of the interviewee. The interviewee identifies a challenging incident from memory; the interviewer elicits a timeline of the incident, and then applies cognitive probes and hypotheticals to explore assessments, goals, and strategies. For this study, we adapted the method to focus on a recent patient encounter so that we could request permission from the patient to access their electronic health record during the interview as a memory support. This interview technique was selected because of its strength in obtaining rich detail and increased accuracy over more general interviews. (13, 14)

Interviews were conducted with individual PCCs by 1–3 interviewers, lasting approximately 60 min. After the first 15 interviews, we conducted preliminary analysis and refined the interview guide to include questions about opioid-related risks, benefits, and goals. In order to accommodate clinician time constraints and increase standardization, we also shifted to a more streamlined interview approach, adhering more closely to the interview guide and restricting follow-up questions to clarifications (see ESM 1) for initial interview guide with refinements highlighted).

We conducted a thematic analysis on deidentified interview transcripts, examining both abstract descriptions of each participant’s general approach to managing patients with chronic pain and specific examples. (15, 16) To develop a codebook, each team member (four behavioral researchers, two primary care clinicians, one pain specialist physician) reviewed two transcripts and identified potential coding categories that would support the team in articulating themes. Potential coding categories were influenced by the curiosity of the research team, the overall study goal of identifying leverage points for supporting PCCs in managing patients with chronic pain, and the data itself. Two of the behavioral researchers were health services researchers and two were cognitive engineers. Four behavioral researchers compiled responses and applied the resulting draft codebook to three interview transcripts using Dedoose version 8.1.10. The analysis team met after each to discuss and refine until consensus was reached about the codebook. Two behavioral researchers then coded remaining interview transcripts as they became available, meeting after each to reach consensus on all codes. Behavioral researchers discussed recurring themes and new ideas throughout the process, determining that thematic saturation had been reached when no new themes emerged after analyzing transcripts from several consecutive participants. (10,11,12)

FINDINGS

Clinician Characteristics

Our sample included 20 PCCs, who represented 13 clinics across three not-for-profit Indiana healthcare systems (Table 1).

Table 1 Participant Characteristics

Strategies to Encourage and Motivate Patients

PCCs described deliberate strategies they find effective in managing patients with chronic pain. Many emphasized that chronic pain influences all aspects of a patient’s life. Thus, the PCC is often in a role of encouraging and motivating patients to adhere to treatment recommendations, to make lifestyle changes, to accept limitations, and to celebrate progress. We identified four themes related to encouraging and motivating patients: (1) developing trust, (2) eliciting information from the patient, (3) diverting attention from pain to function, and (4) articulating realistic goals for the patient.

Developing Trust

Some PCCs emphasized deliberate strategies they use to develop trust with patients. One described active listening: “I’m listening, which is a very important thing I think in connecting with a human being is to listen to them. When I am asking questions, … I am actually really trying to say … I am interested in what you are concerned about. The questions create this bridge where there is trust, so they know I care and trust me.”

Some highlighted how much can be learned by letting the patient talk, particularly for patient populations that find it difficult to ask for help:

… letting him talk, getting him to ramble. I mean, listen to him about his cars and all that stuff, …, but you get them to where they are comfortable and then over a period of time … they spill their guts and you know what’s going on. Because, especially middle-aged rural men, they aren’t going to tell you. I mean, ‘you can ask me all kinds of things that I know are important, that you may have a legitimate need to know, but I’m not going to tell you. I’m going to manage ... I take care of my own problems,’ and so that’s the mentality, so you’ve got to sneak it, you’ve got to get it out of them whenever you can…

Eliciting Information from the Patient

PCCs emphasized the importance of eliciting information from the patient to inform the pain management plan. One PCC explained: “Yeah, I just try to ask more and more specific questions you know to try to get as objective of responses as I can to you know kind of standard questions, rather than [accepting the response:] ‘oh this is like horrible.’ So, say: ‘what’s horrible about it, show me where does it hurt, show me exactly where, you know?’ Stuff like that.”

Another PCC characterized eliciting patient motivations as mining for gold: “And if they haven’t developed a motivation, I kind of think about talking to a patient is like mining for gold, you have to sift through a lot of dirt to get the little gold nuggets. So, trying to help them identify that and creating tiny little gold.”

Diverting Attention from Pain to Function

PCCs explained how some patients become captive by their pain: “The twilight zone, you know, like you can’t escape.” To address this, some PCCs described deliberate strategies to shift the focus from pain to function using a “small steps” strategy. One described asking patients: “What kind of activities are you able to get done with your pain the way it is right now?” and recording the response every time so the PCC could highlight improvements over time. This was a shift from that PCC’s previous pain-focused approach that included asking patients to rate pain on a scale of 1 to 10 during each visit. A common emphasis is understanding how pain limits the patient’s life and what s/he would like to be able to do that s/he cannot. One PCC described the conversation this way “…okay, we want to improve your functioning, and what does that mean for you? Does that mean being able to go to church? Or being able to go to the park with your grandkids…”

Articulating Realistic Goals for the Patient

Efforts to learn more about the patient’s limitations and goals support the PCC’s ability to articulate realistic goals for the patient. A common theme among PCCs is the effort to help patients understand that their pain is not going to go away completely: “I try to make sure that the patient understands what realistic goals for care are, that we’re probably not going to make the pain go away, but at least we can make them more functional.” One PCC reported that they take a more directive approach when managing chronic pain: “…I used to have the patients set the goals more. That is a change. That’s a big change from what I used to do five years ago, for example…. I definitely do a lot more setting the goals, but you know explaining why.”

A discussion about goals often involves explaining to patients that opioids may mask pain, but they do not actually treat the problem; therefore, reducing or limiting use of opioids is an important goal. Some indicated that this conversation has become easier as the risks of opioid therapy have been highlighted in the news in recent years, setting the stage for a discussion of realistic goals: It wasn’t just in the medical literature that there was a problem, it was in lay press that there were problems, so the environment changed. And because of that, it made it easier to say to patients, well yeah, I know you’ve got pain, but I don’t think these pain medicines, these narcotics are what you need, or I sure don’t think a bunch of it is what you need, maybe limited amounts but no we’re just not going to keep going up and up on the doses.

Beliefs About Opioid Therapy

In response to questions about their approach to managing patients with chronic pain, PCCs often explained their beliefs about opioid therapy. We use the term “belief” to refer to statements describing PCC’s understanding of opioids and their effects on patients with chronic pain. PCCs described these beliefs as evolving insights and offered underlying rationale that informed patient interactions and treatment approaches. Three themes emerged from these data: (1) Opioid use tends to reduce function, (2) Opioids are often not effective for long-term pain treatment, and (3) Response to opioids is highly variable.

Opioid Use Tends to Reduce Function

Many PCCs explained that opioids reduce patients’ ability to function in other aspects of their lives. Some noted that people on opioids tend to neglect other aspects of health: “One of the big concerns in my mind and in a lot of people’s minds now is that people on chronic opioids -- what is clear just by observing these people -- is that they neglect a lot of their other health…and I can’t give you any published data on that.” Others reported observable improvements in other health measures when patients are weaned from opioids. Some reported that cognitive function improves when people stop using opioids: I’ve seen patients who get off opioids and benzodiazepines and say: “I can finally think”… and their cognitive functioning improves. One PCC framed this issue in terms of motivation: “That tool [opioids] helps kind of taking away that, you know, that drive….” Many PCCs recalled first-hand experiences with patients and anecdotes that influenced their beliefs about the effect of opioid use on function.

Opioids Are Often Not Effective for Long-term Pain Treatment

Many PCCs reported that opioids are not effective for treating chronic pain over time. Some frame this in terms of building up a tolerance to the medication: “Because of the tolerance that people build up to opioids, they don’t really work well in the majority of patients.” One went further, indicating that not only are opioids less effective over time, but they can exacerbate pain symptoms: “the longer somebody is on [opioid] pain medicine, the more pain they actually feel.”

Response to Pain and Opioids Is Highly Variable

PCCs described individual differences in patients they observed. For example, one hypothesized that athletes are better at managing pain in general: “I see people who run, who are marathoners, who are bikers, who continue to work out and know what good pain is and they seem to tolerate things better…. I don’t know if our brain sets up something differently when we learn what good pain is and we expect a little bit of discomfort.…” Another PCC explained that the analgesic effect is not completely predictable: “There are certain people that take limited amounts of opioids on a regular basis, and they seem to do OK, but a lot of people don’t even find them all that useful over time.” As a result, it is hard to know who will experience pain relief with a specific medication. It is also difficult to determine who will become addicted, and who will become less functional.

See ESM 2 for additional quotes to support these themes.

DISCUSSION

PCC reported beliefs about opioid risks and efficacy generally align with the evidence base. (16) Many PCCs reported a belief that long-term opioid therapy (LTOT) is often not effective for pain relief, although no one in this sample highlighted relevant research findings. (17, 18) Similarly, PCCs generally discussed the link between reduced function and opioid use as an insight they and their colleagues had noted over time rather than an evidence-based finding. (19) One point of controversy is that many report that LTOT can increase pain; yet, there is limited evidence of opioid-induced hyperanalgesia. (20) It is not surprising that observing patients’ inability to manage other chronic conditions while using opioids (or the increase in function after stopping opioids) combined with limited pain relief would be salient to a clinician and reinforce the risks of opioid therapy in a very personal way.

The frequent mention of anecdotes and observed trends as evidence suggests that many of the clinicians in this sample have reflected on and are actively seeking to understand chronic pain and how to most effectively manage patients who experience chronic pain. This is no doubt amplified by the fact that research findings about the effects of LTOT are confusing and contradictory at times. For example, although there is clear risk associated with LTOT, stopping opioids may increase risk in some cases (21), and opioid tapering may exacerbate pain. (22, 23)

In discussion of strategies to motivate and encourage patients, it is notable that many PCCs in our sample described their approach as unconventional. Deliberately making time to develop trust in the context of chronic pain involves having the skills to elicit and listen for indirect cues, flawed beliefs, and goals that may motivate the patient. Prior studies indicating that many patients with chronic pain report feeling distrusted and that their symptoms and concerns were dismissed as trivial in interactions with the PCCs and specialists (6, 8, 24) align with our participants’ perception that these effective, but time-consuming, strategies to build trust are not universal. Many described a shift in approach as they have come to understand chronic pain more fully. Remarkably, PCCs in this study found ways to develop relationships and facilitate discussion of risks and goals, in spite of the well-documented time constraints in primary care. (25, 26) Future research into LTOT use should be informed by these insightful experiences from the front lines.

One implication of these findings is that much of the knowledge and insight that drives chronic pain management is currently acquired via experience. It is important to note that the PCCs who volunteered to participate in this study may be clinicians who have thought deeply about chronic pain. Other PCCs who have limited experience prescribing opioids may have little knowledge of the negative effects beyond addiction and misuse. There is a need for a shared clinical framework for conceptualizing the management of chronic pain and the deployment of LTOT and its consequences. Less-experienced PCCs may benefit from practical explanations of the impact of opioid therapy on function, as well as strategies experienced PCCs have developed for managing chronic pain.

Notably, the Centers for Disease Control and Prevention and the Food and Drug Administration provide evidence-based resources that are universally available. We recommend that primary care organizations explore strategies for integrating these materials into staff meetings and continuing education so that PCCs have an opportunity to discuss research findings and recommendations with colleagues and clinic leadership. Moving research findings into clinic practice via organizational initiatives and clinical cognitive support may increase the likelihood that clinicians will appropriately leverage findings in practice. Even some of the PCCs in this study who have a strong interest in chronic pain reported difficulty finding the time to learn about and integrate the latest research without organizational support. Ready access to research findings that are directly relevant to assessment and treatment planning may help place personal observations in a larger context and guide decision-making. One promising approach is the introduction of Special Care Access Network Extension for Community Healthcare Outcomes (SCAN-ECHO) programs by the Veterans Health Administration to help educate PCCs about effective chronic pain management.

A second implication of these findings is that creating organizational change to better accommodate the needs of patients with chronic pain may be beneficial. In many ways, treating pain is a problem of time. It takes time to establish rapport and trust, elicit information about pain, and manage patient expectations. One common strategy to manage time is to delegate tasks, leveraging support staff such as licensed practical nurses. For chronic pain, this has limited utility and, in fact, may be a barrier to the much-needed rapport and trust. Thus, in spite of the many barriers, we recommend exploration of strategies to increase the time available for PCCs to interact with patients with chronic pain.

A third implication is that time is ripe for innovations to better support PCCs in managing patients with chronic noncancer pain. Clinical cognitive support applications that provide context-specific recommendations and resources tailored to specific patients are recommended. For example, one promising approach is to provide visualizations that aid PCCs in quickly reviewing current and historical treatment plans, as they are reminded of applicable, evidence-based treatment options. (27)

There are important limitations to this study. First, PCCs who volunteered to participate in this study are likely those with an interest in chronic pain and thus may be more knowledgeable on this topic than others. Second, participants were recruited from a single region of the USA that has been hit particularly hard by the opioid crisis at a time when opioid prescribing and opioid deaths were prominent in the news cycle. This likely has influenced beliefs and practice in ways that may be different from other regions, and may have steered our interviewees toward the challenges associated with opioid prescribing over other relevant pain management topics. Third, our analysis focused primarily on challenging cases; therefore, cases in which patients did well with opioid therapy are under-represented in this discussion. Fourth, some PCCs participated in more interviews than others and thus had more opportunity to provide examples and insights.

CONCLUSIONS

This paper highlights how PCCs’ experiences inform their beliefs about LTOT and guide their evolving strategies for assessing and treating patients with chronic noncancer pain. PCC beliefs about opioid therapy generally align with the research base but may have some important gaps. In the context of the opioid epidemic in the USA, many PCCs are actively seeking information and developing hypotheses about the effectiveness of opioids, as well as the dangers. Furthermore, many report that the strategies they have developed to motivate patients with chronic pain require time that is difficult to find in the typical U.S.-based primary care clinic.

This creates fertile ground for interventions that are not pharmacological, but rather focus on (1) strategies to make research findings readily accessible, (2) mechanisms to support those experienced with managing patients with chronic pain in sharing knowledge and effective strategies they have developed, and (3) developing models of care that support PCCs in spending time with patients to develop rapport and trust, elicit information about pain, and manage patient expectations.

Although the findings reported here represent beliefs and strategies in the context of the opioid crisis in the USA, the implications of these findings are likely to be relevant beyond this time and context. PCCs will continue to provide care for patients with chronic pain long after the current opioid crisis is over.
