Income as a Predictor of Self-Efficacy for Managing Pain and for Coping With Symptoms Among Patients With Chronic Low Back Pain

OBJECTIVES

The purpose of this study was to evaluate pain self-efficacy (PSE) and coping self-efficacy (CSE) for people with chronic low back pain (CLBP), and to assess whether lower income may be associated with less PSE and CSE in the United States.

METHODS

We conducted a cross-sectional study using survey data collected between June 2016 and February 2017 from n = 1364 patients with CLBP from chiropractic clinics in the United States to measure the relationship between income and both types of self-efficacy. We created 4 multivariate models predicting PSE and CSE scores. We used both a parsimonious set of covariates (age, sex) and a full set (age, sex, education, neck pain comorbidity, catastrophizing, and insurance). We also calculated effect sizes (Cohen's d) for unadjusted differences in PSE and CSE score by income.

RESULTS

Lower income was associated with lower PSE and CSE scores across all 4 models. In the full models, the highest-income group had an average of 1 point (1-10 scale) higher PSE score and CSE score compared to the lowest income group. Effect sizes for the unadjusted differences in PSE and CSE scores between the highest and lowest income groups were 0.94 and 0.84, respectively.

CONCLUSIONS

Our findings indicate that people with lower income perceive themselves as less able to manage their pain, and that this relationship exists even after taking into account factors like health insurance and educational attainment. There is a need to further investigate how practitioners and policymakers can best support low-income patients with chronic pain.

Predictors of visit frequency for patients using ongoing chiropractic care for chronic low back and chronic neck pain; analysis of observational data

BACKGROUND

Chronic spinal pain is prevalent, expensive and long-lasting. Several provider-based nonpharmacologic therapies have now been recommended for chronic low-back pain (CLBP) and chronic neck pain (CNP). However, healthcare and coverage policies provide little guidance or evidence regarding the long-term use of this care. To provide one glimpse into the long-term use of nonpharmacologic provider-based care, this study examines the predictors of visit frequency in a large sample of patients with CLBP and CNP using ongoing chiropractic care.

METHODS

Observational data were collected from a large national sample of chiropractic patients in the US with non-specific CLBP and CNP. Visit frequency was defined as average number of chiropractic visits per month over the 3-month study period. Potential baseline predictor variables were entered into two sets of multi-level models according to a defined causal theory-in this case, Anderson's Behavioral Model of Health Services Use.

RESULTS

Our sample included 852 patients with CLBP and 705 with CNP. Visit frequency varied significantly by chiropractor/clinic, so our models controlled for this clustering. Patients with either condition used an average of 2.3 visits per month. In the final models visit frequency increased (0.44 visits per month, p = .008) for those with CLBP and some coverage for chiropractic, but coverage had little effect on visits for patients with CNP. Patients with worse function or just starting care also had more visits and those near to ending care had fewer visits. However, visit frequency was also determined by the chiropractor/clinic where treatment was received. Chiropractors who reported seeing more patients per day also had patients with higher visit frequency, and the patients of chiropractors with 20 to 30 years of experience had fewer visits per month. In addition, after controlling for both patient and chiropractor characteristics, the state in which care was received made a difference, likely through state-level policies and regulations.

CONCLUSIONS

Chiropractic patients with CLBP and CNP use a range of visit frequencies for their ongoing care. The predictors of these frequencies could be useful for understanding and developing policies for ongoing provider-based care.

Coping and Management Techniques Used by Chronic Low Back Pain Patients Receiving Treatment From Chiropractors

OBJECTIVES

The purpose of this study was to describe coping strategies (eg, mechanisms, including self-treatment) that a person uses to reduce pain and its impact on functioning as reported by patients with chronic low back pain who were seen by doctors of chiropractic and how these coping strategies vary by patient characteristics.

METHODS

Data were collected from a national sample of US chiropractic patients recruited from chiropractic practices in 6 states from major geographical regions of the United States using a multistage stratified sampling strategy. Reports of coping behaviors used to manage pain during the past 6 months were used to create counts across 6 domains: cognitive, self-care, environmental, medical care, social activities, and work. Exploratory analyses examined counts in domains and frequencies of individual items by levels of patient characteristics.

RESULTS

A total of 1677 respondents with chronic low back pain reported using an average of 9 coping behaviors in the prior 6 months. Use of more types of behaviors were reported among those with more severe back pain, who rated their health as fair or poor and who had daily occurrences of pain. Exercise was more frequent among the healthy and those with less pain. Female respondents tended to report using more coping behaviors than men, and Hispanics more than non-Hispanics.

CONCLUSION

Persons with chronic back pain were proactive in their coping strategies and frequently used self-care coping strategies like those provided by chiropractors in patient education. In alignment with patients' beliefs that their condition was chronic and lifelong, many patients attempted a wide range of coping strategies to relieve their pain.

Prevalence and Characteristics of Chronic Spinal Pain Patients with Different Hopes (Treatment Goals) for Ongoing Chiropractic Care

Objectives: The treatment goals of patients successfully using ongoing provider-based care for chronic spinal pain can help inform health policy related to this care. Design: Multinomial logistical hierarchical linear models were used to examine the characteristics of patients with different treatment goals for their ongoing care. Settings/Location: Observational data from a large national sample of patients from 125 chiropractic clinics clustered in 6 U.S. regions. Subjects: Patients with nonwork-injury-related nonspecific chronic low-back pain (CLBP) and chronic neck pain (CNP). Interventions: All were receiving ongoing chiropractic care. Outcome measures: Primary outcomes were patient endorsement of one of four goals for their treatment. Explanatory variables included pain characteristics, pain beliefs, goals for mobility/flexibility, demographics, and other psychological variables. Results: Across our sample of 1614 patients (885 with CLBP and 729 with CNP) just under one-third endorsed a treatment goal of having their pain go away permanently (cure). The rest had goals of preventing their pain from coming back (22% CLBP, 16% CNP); preventing their pain from getting worse (14% CLBP, 12% CNP); or temporarily relieving their pain (31% CLBP, 41% CNP). In univariate analysis across these goals, patients differed significantly on almost all variables. In the multinomial logistic models, a goal of cure was associated with shorter pain duration and more belief in a medical cure; a goal of preventing pain from coming back was associated with lower pain levels; and those with goals of preventing their pain from getting worse or temporarily relieving pain were similar, including in having their pain longer. Conclusions: Although much of health policy follows a curative model, the majority of these CLBP and CNP patients have goals of pain management (using ongoing care) rather than "cure" (care with a specific end) for their chiropractic care. This information could be useful in crafting policy for patients facing provider-based nonpharmacologic care for chronic pain.

Researching the Appropriateness of Care in the Complementary and Integrative Health Professions Part 4: Putting Practice Back Into Evidence-based Practice by Recruiting Clinics and Patients

OBJECTIVES

This paper focuses on the methods of a single study, incorporating data from chiropractic clinics into an evidenced-based investigation of the appropriateness of manipulation for chronic back pain.

METHODS

A cluster sample of clinics (125) from 6 sites across the United States was chosen for this observation study. Patients with chronic low-back and neck pain were recruited using iPads, completed a series of online questionnaires, and gave permission for their patient records to be scanned. Patient records for a random sample were also obtained. The RAND staff and clinic personnel collected record data.

RESULTS

We obtained survey data from 2024 patients with chronic low back pain, chronic neck pain, or both. We obtained patient record data from 114 of 125 clinics. These included the records of 1475 of the individuals who had completed surveys (prospective sample), and a random sample of 2128 patients. Across 114 clinics, 22% of clinics had patient records that were fully electronic, 32% had paper files, and 46% used a combination. Of the 114 clinics, about 47% scanned the records themselves with training from RAND. We obtained a total of 3603 scanned records. The patient survey data were collected from June 2016 to February 2017, the provider surveys from June 2016 to March 2017, and the chart pull from April 2017 to December 2017.

CONCLUSIONS

Clinics can be successfully recruited for practice-based studies, and patients can be recruited using iPads. Obtaining patient records presents considerable challenges, and clinics varied in whether they had electronic files, nonelectronic records, or a mixture. Clinic staff can be trained to select and scan samples of charts to comply with randomization and data protection protocols in transferring records for research purposes.

Researching the Appropriateness of Care in the Complementary and Integrative Health Professions Part 3: Designing Instruments With Patient Input

OBJECTIVES

The purpose of this article is to describe how we designed patient survey instruments to ensure that patient data about preferences and experience could be included in appropriateness decisions. These actions were part of a project that examined the appropriateness of spinal manipulation and mobilization for chronic low back pain and chronic neck pain.

METHODS

We conducted focus groups, cognitive interviews, a literature review of measures in prior chiropractic and complementary and integrative health research, and a pilot study to develop questionnaires of patient preferences, experiences, values, and beliefs.

RESULTS

Questionnaires were administered online to 2024 individuals from 125 chiropractic clinics. The survey included 3 long questionnaires and 5 shorter ones. All were administered online. The baseline items had 2 questionnaires that respondents could complete in different sittings. Respondents completed shorter biweekly follow-ups every 2 weeks and a final questionnaire at 3 months. The 2 initial questionnaires had 81 and 140 items, the 5 biweekly follow-up questionnaires had 37 items each, and the endline questionnaire contained 121 items. Participants generally responded positively to the survey items, and 91% of the patients who completed a baseline questionnaire completed the endpoint survey 3 months later. We used "legacy" measures, and we also adapted measures and developed new measures for this study. Preliminary assessment of reliability and validity for a newly developed scale about coping behaviors indicates that the items work well together in a scale.

CONCLUSIONS

This article documents the challenges and the efforts involved in designing data collection tools to facilitate the inclusion of patient data into appropriateness decisions.
