This study aimed to explore the extent to which documenting chronic pain on a problem list was associated with the utilization of specialty pain care. To date, no study has examined the documentation of chronic pain in the problem list. However, compared to problem list studies examining other chronic diseases, this study has some similarities and differences. This study discovered that providers documented chronic pain in 82.5% of patients’ problem lists. These findings contrast with recent literature suggesting that chronic pain documentation rates are augmented in pain management training programs. In these instances, there was an increase in documenting chronic pain on the problem list from 0.5–2.4% [16]. Although the higher documentation rates found in this study are promising, it is essential to note that this was a single metropolitan area.
The majority of the sample was female although the rates of chronic pain documentation were similar in men and women. Compared to their male counterparts, females are more likely to utilize pain management options [24]. Therefore, higher utilization of pain management options might be associated with an increase in documentation of chronic pain on the problem list. Among patients diagnosed with chronic pain syndrome, 93.5% had chronic pain documented on their problem list, compared to 77.2% of patients diagnosed with migraine. Chronic pain syndrome is associated with psychological and physiological disability [25, 26]. The difference between a diagnosis of chronic pain syndrome and the non-specific other chronic pain diagnoses comes down to the psychological aspect of the pain experience [26]. The additional components of the psychological strain encompassed in the chronic pain syndrome diagnosis may reflect the rate at which providers document the problem. The increase in documentation may be due to several competing symptoms that increase the chance of documentation, rather than pain alone.
Other chronic pain was the most common diagnosis in this study. Similarly, the most frequently documented problem was chronic pain. Disease documentation and treatment are essential steps in the long-term management of chronic diseases. Experts recommend collecting information regarding the patient's pain history, location, severity, duration, and possible causes [27, 28]. However, primary care adherence to pain care standards, documentation, and practice is known to be inadequate [29]. The ambiguity behind diagnosing various issues as a single chronic pain diagnosis makes tracking patient care difficult. On the problem list, 10% of patients had back pain. The treatment of back pain versus chest pain, which was never listed as a problem, is vastly different. However, outside of back pain, there is no specificity for the patient's type of pain. Although guidelines provide the best practices for managing chronic pain through pharmacological or non-pharmacological therapies [30], clarity of the kind of chronic pain the patient may suffer is essential.
Recognition of heart failure and chronic kidney disease on the problem list was associated with more evidence-based management [11, 13, 15], These findings are consistent with those of our study, which showed that documenting chronic pain on the problem list was associated with a higher likelihood of utilizing specialty pain care. The relationship between documenting pain as a problem and receiving follow-up care might be related to the provider. One might postulate that a provider with more chronic pain training may explain the association between these findings. Further research will need to address provider differences and stratify whether the result of a complete problem list is due to the additional awareness of the actual problem or the provision of better comprehensive care in general.
After controlling for all other covariates, including clinic clusters, sex was found to be significantly associated with the utilization of pain specialty care. As stated previously, a 3% difference in the rates of problem list completion between males and females is statistically significant, but minor differences in a large sample may show up as significant and the clinic significance is questionable [31]. The other unclassified chronic pain group had increased utilization of specialty pain care. Migraine sufferers had decreased odds of using specialty pain care. This result is expected since migraine sufferers have clear established pain management guidelines, and specialty care is often unnecessary [32–34].
A limitation of this study was the absence of provider characteristics or information. The association between problem list completion and treatment follow-up may be due to unmeasured provider differences. Research has shown that a provider's age can impact the type of care a person receives [35]. However, there is no literature exploring the variation between provider-to-patient demographic differences. Furthermore, there is the possibility that the better the physician, the more likely they are to document the problem on the problem list and recommend the patient to specialty care. The difference could be due to this confounding factor and not the documentation of chronic pain.
Another limitation is that the healthcare network is an open network system. Therefore, if a patient sees a provider and obtains a referral for a pain specialist, we cannot determine whether the patient saw a pain specialist outside of the network. It is entirely possible that a small portion of patients with chronic pain had a follow-up with a pain specialty clinic outside the hospital network and, therefore, were tracked as not receiving care under this dataset. Owing to the nature of the retrospective review of EHR data, the data are only as reliable and clean as the providers put into the system. Psychosocial factors, such as substance use, are often less complete than other required fields, limiting researchers’ ability to control these factors.
A strength of this study was the inclusion of a large number of clinics and patients. Although these clinics are all in one healthcare network, individual primary care clinics have their own pain management policies and practices. Such variability among these clinics increases their generalizability to other clinics within the California Metropolitan Area. Furthermore, this study is an essential first step toward value-based care. Value-based programs reward healthcare providers with incentives to provide quality care to patients with Medicare [30, 36]. This patient-centered care model prioritizes patient health outcomes [36]. Value-based care focuses on high-value care such as preventative strategies rather than first-line defense such as opioids [37]. Research such as this study helps identify new pathways to provide the best care to patients utilizing our current resources.
4.1 Conclusion
Chronic pain is complex and requires a multifaceted approach to manage it. Often, a lack of clarity in the documentation of chronic pain may lead to unclear treatment options. However, utilizing EHR as a supportive tool in the pain management process may reduce such ambiguity. This is the first study to discover an association between chronic pain documentation on a problem list and patient follow-up with specialty pain care. Further research is required to explore these findings across different health systems and locations. This study may inform future research looking at automating problem list entries based on the relevant problems that the research supports.
