Healthcare provider relational quality is associated with better self-management and less treatment burden in people with multiple chronic conditions.

PURPOSE: Having multiple chronic conditions (MCCs) can lead to appreciable treatment and self-management burden. Healthcare provider relational quality (HPRQ) - the communicative and interpersonal skill of the provider - may mitigate treatment burden and promote self-management. The objectives of this study were to 1) identify the associations between HPRQ, treatment burden, and psychosocial outcomes in adults with MCCs, and 2) determine if certain indicators of HPRQ are more strongly associated than others with these outcomes. PATIENTS AND METHODS: This is a cross-sectional survey study of 332 people with MCCs. Patients completed a 7-item measure of HPRQ and measures of treatment and self-management burden, chronic condition distress, self-efficacy, provider satisfaction, medication adherence, and physical and mental health. Associations between HPRQ, treatment burden, and psychosocial outcomes were determined using correlational analyses and independent samples t-tests, which were repeated in item-level analyses to explore which indicators of HPRQ were most strongly associated with the outcomes.
RESULTS: Most respondents (69%) were diagnosed with ≥3 chronic conditions. Better HPRQ was found to be associated with less treatment and self-management burden and better psychosocial outcomes (P<0.001), even after controlling for physical and mental health. Those reporting 100% adherence to prescribed medications had higher HPRQ scores than those reporting less than perfect adherence (P<0.001). HPRQ items showing the strongest associations with outcomes were "my healthcare provider spends enough time with me", "my healthcare provider listens carefully to me", and "I have trust in my healthcare provider".
CONCLUSION: Good communication and interpersonal skills of healthcare providers may lessen feelings of treatment burden and empower patients to feel confident in their self-management. Patient trust in the provider is an important element of HPRQ. Educating healthcare providers about the importance of interpersonal and relational skills could lead to more patient-centered care.

Introduction

Many of today’s chronic illnesses require continuous self-management. The ability to self-manage is critical and has been closely tied to physical and mental health outcomes across a range of chronic illnesses.1 Self-management requirements are often magnified in patients coping with multiple chronic conditions (MCCs). In populations with MCCs, increasing difficulty with performing self-management tasks has been linked to declines in physical and mental health.2 Moreover, patient perception of treatment and self-management burden, that is, the perceived “workload” of health care and its impact on functioning and well-being, has been associated with greater distress, lower self-efficacy, and poorer adherence to prescribed medications.3 Identifying factors that may relieve treatment and self-management burden and promote self-management capabilities could facilitate patients’ engagement with their care and improve outcomes.

In a recent qualitative study, we found that a number of factors may lessen feelings of treatment and self-management burden in patients with MCCs.4 Prominent among these were positive and constructive elements of the patient–provider relationship, including good provider communication and listening skills. Prior studies have shown that better provider communication is associated with better patient self-management and adherence to medical regimens,5–9 with the relationship possibly being mediated by health self-efficacy.10 Conversely, perceptions of hurried communication (eg, doctors speaking too fast, using complex words, appearing distracted) have been related to poorer patient outcomes.11 Theoretical mechanisms of the impact of provider communication on patient health outcomes point to indirect effects, such that better patient–provider communication influences health outcomes through intermediate outcomes like improved adherence to medical regimens.12

Beyond communicative skill, studies also point to the importance of provider interpersonal skills, especially those that engender feelings of trust and respect from patients. “High-performing” physicians report establishing trust with their patients by maintaining eye contact, conveying empathy and understanding, leaning forward in their chair when speaking with patients, smiling, and not looking hurried.13 Feeling trust in one’s physician has been linked to greater adherence to treatment recommendations, including medication adherence14,15 and engagement in healthy behaviors like exercise and smoking cessation.16 Chronically ill patients who feel greater trust and security in their relationships with providers may feel more empowered, confident, and motivated to manage the demands of their illness.17 Conversely, patients who perceive a lack of respect from their providers may develop negative attitudes about their prescribed care regimens. In a recent meta-synthesis of qualitative studies, Mohammed et al found that patients preferred to self-manage their medicines, sometimes with negative consequences, when they perceived that their providers were not giving them adequate time at appointments, were not paying enough attention to them, or seemed unwilling to consider their life circumstances.18 Proposed theoretical pathways support that a strong therapeutic alliance between healthcare professionals, patients, and caregivers (ie, a relationship that engenders trust and respect among all parties) can lead to better health outcomes indirectly by lowering patient distress, increasing satisfaction with providers, and enhancing patient commitment to treatment plans.12

Study objectives

An understanding of the quality of the patient–provider relationship requires attention to not only the provider’s ability to communicate but also his/her interpersonal and relational skills,19 a distinction that was articulated some 30 years ago in seminal work by Hall et al.20 Comprehensive measures of communication and other aspects of the patient–provider relationship are available, such as the Interpersonal Processes of Care Survey,21 the Picker Institute Patient Experience Questionnaire,22 the Consumer Assessment of Healthcare Providers and Systems (CAHPS®) Clinician and Group Survey (CG-CAHPS),23 and the Trust in Physicians Survey.24 Such measures are typically used to assess the patient’s perception of the relationship with one particular type of provider, the physician. However, patients with multi-morbidity seen in primary care clinics are often treated by healthcare teams that involve more than one type of healthcare provider. A brief measure of the patient–provider relationship that does not specify a provider type may offer a useful alternative for studies of patients with MCCs seen in primary care settings. With this backdrop, we formed 2 study objectives. First, we aimed to identify the associations between healthcare provider relational quality (HPRQ) – defined here as the communicative and interpersonal skill of the healthcare provider – and various self-management and psychosocial outcomes in adults with MCCs. To investigate these relationships, we employed a brief measure of HPRQ developed specifically for use in our studies of the treatment burden construct.3,4 The measure does not specify a provider type. Second, we were interested in determining if certain indicators of HPRQ are more strongly associated than others with self-management and psychosocial outcomes in adults with MCCs. This study represents a secondary analysis of data collected for a previously conducted study to validate a novel patient-reported measure of treatment burden.3

Patients and methods

Sample

Participants with MCCs were recruited from the Hennepin County Medical Center (Minneapolis, MN, USA) and the Mayo Clinic (Rochester, MN, USA) as part of a prior survey study to validate a novel patient-reported measure of treatment burden.3 Hennepin County Medical Center is Minnesota’s largest public “safety-net” hospital providing care to many low-income, uninsured, and vulnerable persons. Mayo Clinic is a large, multispecialty, integrated practice located in southeast Minnesota. Patients were eligible if they 1) were ≥21 years old, 2) were assigned to a primary care provider at either site, 3) had medical record-confirmed diagnoses of ≥2 chronic conditions (specifically conditions requiring self-management),25–28 and 4) had at least 1 medical record-confirmed encounter with a provider at either site within the past 18 months for their chronic conditions. Patients were ineligible if they had no documented research authorization per Minnesota state privacy law, Statute 144.335, 1997. Minnesota state law requires that healthcare providers obtain authorization to use health records for research from all patients who have received medical care after January 1, 1997. This includes consent to contact individuals for research. Patients lacking English language proficiency were excluded. A stratified random sample of 838 people was drawn from a list of eligible patients identified from the medical records of the 2 sites. Stratification factors included number of diagnosed conditions (2, 3, or 4+), number of encounters with a provider in the past 18 months (1–8, 9–17, 18+), and age (<65 or ≥65). The sample size was based on having adequate power for the psychometric analyses of the previously conducted treatment burden measure validation study3 with expectation of a minimum survey return rate of 40%.

Procedure

A survey booklet consisting of study measures was prepared by the Mayo Clinic Survey Research Center and mailed to eligible patients along with a cover letter, a small gift to encourage participation (designer pen or $3 gift card), and a postage-paid return envelope. To maximize returns, a second mailing to nonrespondents occurred 3 weeks after the first. The study was deemed exempt by both site Institutional Review Boards under category 2 of Title 45 Code of Federal Regulations (CFR) Part 46.101 (Protection of Human Subjects). A research study is eligible for category 2 exempt status if 1) it does not involve prisoners, 2) it does not involve an approved FDA-regulated product used in the course of medical practice, and 3) it is research that involves only the use of educational tests or survey procedures with (i) the information obtained recorded in such a manner that human subjects cannot be identified, either directly or through identifiers, and (ii) any disclosure of human subjects’ responses outside the research would not reasonably place the subjects at risk of criminal or civil liability or be damaging to their financial standing, employability, or reputation. The research involved no procedures for which written consent is normally required outside of the research context (ie, the surveys); all criteria for waiver of consent documentation were met in accordance with 45 CFR 46.117, and hence, waiver of consent documentation was approved. The cover letter described the survey study, including how data would be aggregated for analysis and kept secure, and participants were told to skip any questions they did not want to answer. Participant anonymity was preserved in the following ways: 1) names and addresses were only recorded to create mailing address labels, 2) a unique study identifier was used to track survey returns and to link with medical record data, 3) returned survey data were pooled across all participants and only an aggregated dataset was analyzed (ie, no individual was identifiable in any analysis or report), and 4) the file containing participant names and addresses used to create mailing labels and link with medical record data was destroyed at the conclusion of the study. This report represents a secondary analysis of data collected for the treatment burden measure validation study.3 Several of the measures used were selected specifically to assess construct validity of the treatment burden measure developed in the parent study.

Study measures

Healthcare provider relational quality

Informed by a conceptual framework of factors that may lessen treatment burden in people self-managing MCCs,4 we created a brief, 7-item patient-reported measure of HPRQ. Items were written to operationalize specific patient experiences and issues as reflected in patient interviews and focus groups.4 These same interviews and focus groups were previously used to inform content for a novel measure of treatment burden.3 Some questions were adapted from items embedded within the Doctor Communication composite of the CG-CAHPS,23 and others were newly written. Items were reviewed by healthcare providers, health services researchers, and patient advocates and were cognitively pretested in patients with MCCs.3 In 2 rounds of cognitive interviews with 23 patients, all of the items of the HPRQ measure were found to be easy to understand and were rated as highly relevant and important aspects of health care. Details of the cognitive interviewing procedure are available in an online supplement to the study of Eton et al.3

The HPRQ measure defines a “healthcare provider” as “any doctor, nurse, or other health professional that helps treat you and provides you with medical care”. Respondents are asked to think about their current health care and determine their agreement with the following statements: 1) My provider(s) listens carefully to me, 2) It is easy to communicate with my provider(s), 3) My provider(s) treats me with dignity and respect, 4) My provider(s) is up to date on my medical history, 5) My provider(s) spends enough time with me, 6) My provider(s) treats me as a whole person, and 7) I have trust in my provider(s). All items use a 4-point response scale ranging from strongly disagree to strongly agree. A raw score is computed by summing the item scores, imputing any unanswered items with the mean of the completed items as long as >50% of the items (ie, 4 of 7) are answered. Imputing missing item scores in this manner has been used with other patient-reported measures.29 The raw score is transformed to a standardized 0–100 metric with a higher score indicative of better HPRQ.

Treatment burden

Three scales from the Patient Experience with Treatment and Self-management (PETS), a recently validated patient-reported measure of perceived treatment burden,3 were used in this analysis. Scales included the 7-item Medical Information Burden scale, the 7-item Difficulty with Healthcare Services scale, and the 5-item Physical/Mental Exhaustion due to self-management scale. The items making up these scales are found in Table S1. Scale scores are standardized to a 0–100 metric with higher scores indicating greater treatment burden. The 3-item Convenience subscale of the Treatment Satisfaction Questionnaire for Medication (TSQM)30 was used to assess the ease and convenience of taking required medications for one’s health conditions. Higher scores indicate greater perceived convenience. Both the PETS and TSQM are psychometrically sound and valid measures in patients with chronic health conditions.3,30

Distress, self-efficacy, satisfaction with provider, and medication adherence

A 5-item Chronic Condition Distress Scale (CCDS) was adapted from the Diabetes Distress Scale31 and specified generally for “health problems” (L Fisher, personal communication). The scale assesses a general feeling of distress associated with living with a chronic health condition (eg, feeling overwhelmed, feeling your friends or family are not providing you enough support, feeling your health condition keeps you from enjoying life). Wallston’s 8-item Perceived Medical Condition Self-management (PMCSM) scale was used to assess self-efficacy or perceived competence in managing one’s health condition.32 These measures have been shown to be reliable and valid in patients with chronic illnesses requiring self-management.31,32

To assess satisfaction with provider, an overall rating of healthcare providers was adapted from a numeric rating scale item of the CG-CAHPS survey.23 The item was tailored to fit this study (ie, “Overall, how would you rate your healthcare providers who treat you and provide you with medical care?”) and used a 0–10 rating scale ranging from “worst healthcare providers possible” (0) to “best healthcare providers possible” (10). A single-item self-report measure was used to assess adherence to physician-recommended medications (“always”, “usually”, or “sometimes”). Lower adherence has been shown to be associated with greater perceived treatment burden3 and worse control of blood pressure in patients with hypertension.14

Demographics and covariates

Demographic characteristics (age, race/ethnicity, and education), number of prescription medications, and overall physical and mental health were assessed using single items. Overall physical and mental health status was assessed using 2 items of the Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 measure. The PROMIS Global-10 provides global assessments of physical and mental health and has been shown to be valid and reliable in patients with chronic illnesses.33 The physical and mental health ratings are used as covariates in this study. Finally, gender, number and types of chronic conditions, and the number of recent encounters with a provider (in last 18 months) were extracted from the electronic medical record.

Analyses

Descriptive statistics (ie, means, medians, and frequency distributions) were used to describe survey respondents. Cronbach’s alpha was used to check the internal consistency reliability of the HPRQ measure.

Association of HPRQ measure and outcomes (study objective 1)

Pearson correlations (r) were used to determine the extent that scores on the HPRQ measure are associated with patient distress, perceived treatment burden, medication convenience, self-management self-efficacy, and satisfaction with provider. We used Cohen’s criterion benchmarks for small (r=0.10), medium (r=0.30), and large (r=0.50) effect sizes to help interpret the relative size of the correlation magnitudes.34 Consistent with findings of prior studies and meta-analytic reviews,7,10,11,18,35 as well as proposed theoretical pathways linking patient–provider communication and relationships to health outcomes,12 we hypothesized that higher (better) HPRQ would be negatively correlated with distress (CCDS score) and perceived treatment burden (PETS scale scores) and positively correlated with medication convenience (TSQM score), self-efficacy (PMCSM score), and satisfaction with provider (healthcare provider rating). Further, we determined whether overall physical and mental health accounts for variance in these relationships by covarying the PROMIS physical and mental health item scores from the pairwise correlations (ie, partial correlation). If these factors are confounders, then the pairwise correlation magnitudes should be reduced and approach 0 once they are statistically controlled.

An independent samples t-test was used to determine whether scores on the HPRQ measure were associated with adherence to physician-prescribed medications. For this analysis, we created distinct groups by dichotomizing responses to the medication adherence question in the same manner as Schoenthaler et al (ie, “always take all my medications” vs “usually/sometimes take all my medications”).14 The magnitude of the group difference was determined using the effect size (Cohen’s d) by dividing the difference of the group means by the pooled SD, with d =0.2, 0.5, and 0.8 considered small, medium, and large effect sizes, respectively.34 Consistent with findings of prior studies, reviews, and meta-analyses,5,6,8,14,15 and proposed theoretical mechanisms linking patient–provider communication and health outcomes,12 we hypothesized that greater adherence to medications would be associated with better HPRQ.

Association of individual items of the HPRQ measure and outcomes (study objective 2)

We explored whether certain indicators of HPRQ were more strongly associated than others with distress, treatment burden, medication convenience, self-efficacy, and satisfaction with provider by correlating each item on the HPRQ measure with each outcome measure. Relative strength of the associations was determined in 2 ways. First, we computed a mean of the correlations of each item with every outcome measure (ie, a mean of the correlation magnitudes across measures). Second, we rank-ordered the strength of the correlation magnitudes of each of the 7 HPRQ items with each individual outcome measure (ie, rank-ordering correlation magnitudes within each outcome measure), and then we computed the median rank for each item across all of the outcome measures. A higher mean correlation magnitude and a higher median rank indicate a stronger association of item with outcomes. Similar parameter-ranking procedures have been used in other studies to compare measurement properties of patient-reported outcome measures.36,37

Finally, we performed independent samples t-tests on the 7 HPRQ items by adherence to prescribed medications (dichotomized), and computed effect sizes (d) for the group differences. Larger effect sizes are indicative of items showing a greater ability to discriminate the groups. Given that directional hypotheses are supported by prior research findings and theoretical mechanisms,5–8,10–12,14,15,18,35 a 1-tailed alpha was used and set at 0.05 for all correlations and group-level comparisons. However, there were no hypotheses regarding which particular HPRQ items would be most strongly associated with the outcomes. All analyses were conducted in IBM SPSS Statistics version 20®.

Results

Sample characteristics

Of 838 mailed surveys, 332 were completed and returned (40% response). In comparing survey responders with non-responders across the stratification factors, more responders (57%) than nonresponders (46%) were ≥65 years of age (P<0.01), and fewer responders (32%) than nonresponders (42%) had only 1–8 encounters with a medical provider in the last 18 months (P<0.01). There were no significant differences between responders and nonresponders in the number of diagnosed conditions. Demographic, medical, and other health-related characteristics of the sample are identified in Table 1. There were more female (56%) than male participants, with a mean age of 66 years (range: 26–90). Most (73%) were white; however, over 20% identified with a racial minority group, including 15% identifying as African American. Most (70%) had at least some formal college or university education, while 27% had no more than a high school education. Among medical variables extracted from the electronic medical record, the median number of diagnosed conditions was 3 (with over one-third having ≥4 conditions) and the median number of encounters with a medical provider in the past 18 months was 13.5. The most common diagnoses were hypertension (77%), lipid metabolic disorders (76%), diabetes (36%), osteoarthritis (36%), and coronary artery disease (19%); however, asthma, chronic kidney disease, depression, glaucoma, and COPD were also common. Sixty-three percent of participants were taking at least 4 prescribed medications, with one-third taking ≥6. Thirty percent felt their physical health was fair or poor, while 23% felt their mental health was fair or poor. Most (78%) reported that they always take all of their medications. Overall satisfaction with healthcare providers was high (mean rating =8.7 out of 10).

Association of HPRQ with outcomes (study objective 1)

Internal consistency reliability of the HPRQ measure was excellent (Cronbach’s alpha =0.96). As shown in Table 2, the HPRQ measure was significantly correlated with several of the outcome measures in hypothesized directions. Higher (better) HPRQ was negatively correlated with chronic condition distress (CCDS: r=−0.31) as well as the 3 scales of the PETS treatment burden measure: Medical Information Burden (r=−0.47), Difficulty with Healthcare Services (r=−0.55), and Physical/Mental Exhaustion with self-management (r=−0.33; all Ps<0.001). Furthermore, higher HPRQ was positively correlated with self-reported convenience of taking required medication (TSQM Convenience: r=0.26), self-management self-efficacy (PMCSM: r=0.33), and overall satisfaction with providers (r=0.55; all Ps<0.001). Most of these correlations (6 of 7 or 86%) were medium to large in magnitude. After controlling for 2 potential confounding variables, self-reported physical and mental health, all correlation magnitudes remained significantly >0 and were in the hypothesized directions (shown by partial correlations in the last 2 columns of Table 2). Correlation magnitudes were slightly attenuated after controlling for these variables; however, 50% (7 of 14) remained in the medium-to-large range. HPRQ was not associated with number of diagnosed conditions, number of encounters with medical providers in the past 18 months, or number of prescription medications.

The HPRQ measure differentiated respondents based on self-reported medication adherence. As hypothesized, survey respondents who reported “always” taking all of their prescribed medications (n=260) reported a higher HPRQ score (mean =82.4) than those who reported taking all of their medications “usually” or “sometimes” (n=51) (mean =70.4; t [294] =3.79, P<0.001; Cohen’s d =0.59, a medium-to-large effect size).

Association of individual HPRQ items with outcomes (study objective 2)

As shown in Table 3, all HPRQ scale items were significantly associated with all outcome measures (all Ps<0.001) with over half of the correlations (29 of 49 or 59%) in the medium-to-large range of magnitude (ie, r≥0.30). A summary of the relative strengths of the associations between items and outcomes is indicated in the last column of the table. This column features the following: 1) the mean of the correlation magnitudes for each item across all outcomes with a higher mean magnitude indicating stronger association with outcomes, and 2) the median rank of the rank-ordered correlation magnitudes of each HPRQ item and each individual outcome measure, with a higher median rank indicating a stronger association of item with outcomes (note: a higher median rank is indicated by a lower number). As shown by the summary statistics in the last column of Table 3, the HPRQ items showing the strongest associations with outcomes were “I have trust in my healthcare provider(s)” (mean r=0.39, median rank =2), “My healthcare provider(s) spends enough time with me” (mean r=0.38, median rank =2), and “My healthcare provider(s) listens carefully to me” (mean r=0.36, median rank =3). All of the mean correlations were just above a medium magnitude.

Finally, independent samples t-tests were conducted on each of the 7 HPRQ items by self-reported adherence to prescribed medications (“always” vs “usually/sometimes”) to determine if certain items were better at discriminating groups. Comparisons of item discriminability were made by comparing effect sizes (d) corresponding to mean differences in item scores between groups, with larger effect sizes indicating greater ability of the item to discriminate. As shown in Figure 1, all 7 HPRQ items discriminated the groups. Respondents who reported “always” taking all of their prescribed medications reported better HPRQ in all aspects than those who reported taking all of their medications “usually” or “sometimes” (all Ps<0.05, effect sizes: 0.37–0.68). Three items discriminated the groups best. Medium-to-large effect sizes34 were observed for “My healthcare provider(s) spends enough time with me” (d =0.68), “My provider(s) listens carefully to me” (d =0.62), and “I have trust in my healthcare provider(s)” (d =0.60).

Discussion

Our study showed that the quality of the patient–provider relationship, as perceived by patients, is associated with self-management, treatment burden, psychosocial outcomes, and satisfaction with providers in people coping with MCCs. Patients who believed that their healthcare providers exhibited good communication and interpersonal skills and treated them with dignity and respect perceived less treatment and self-management burden, reported less distress, felt greater confidence in their ability to self-manage, and were more satisfied with their providers. These relationships remained after controlling for physical and mental health status, and were mostly medium-to-large in magnitude. Furthermore, patients who reported being 100% adherent to prescribed medications perceived better HPRQ than patients who reported less than perfect adherence. HPRQ was not associated with objective indicators such as number of diagnosed conditions, number of recent encounters with providers, or the number of medications being taken. While it is tempting to speculate that having a better relationship with one’s provider might lead to better outcomes, the cross-sectional design of our study precludes drawing causal conclusions. Prospective studies are needed to further specify and test the pathways through which HPRQ operates.12 However, our findings are consistent with those of other studies and meta-analytic reviews that have shown elements of HPRQ to be associated with less distress and perceived treatment burden,11,18 higher self-efficacy,10 better self-management ability,6 greater adherence to treatment,8,11 and satisfaction with healthcare providers.35

We also disaggregated HPRQ to understand the relationship between each of its constituent elements and outcomes. The HPRQ items reflecting that the healthcare provider spends enough time with the patient, listens carefully to the patient, and is trusted by the patient featured the strongest associations with the outcomes, with correlation magnitudes and effect sizes in the medium-to-large range. These items were also most strongly correlated with overall satisfaction with the provider. A recent study by Stucky et al38 has shown that an aggregate scale of 2 CG-CAHPS items, “spending enough time” with the patient and “listening carefully” to the patient, provides nearly equivalent measurement precision as the longer Doctor Communication composite scale in which they are embedded. The aggregate scale maintained the validity of the longer composite, with scores remaining highly correlated with overall satisfaction with the provider.38 Our study confirms use of these 2 items to assess HPRQ.

Our study also supports addition of an overall rating of patient trust in the provider to the measurement of HPRQ. We observed robust associations of this item with patient outcomes, with most correlation magnitudes and effect sizes in the medium-to-large range. Trust is a global impression, an attitude, formed about the provider and stemming from a patient’s belief that the provider is not only technically competent but also honest, empathic, and concerned about the patient’s welfare and best interests.15,39 Measuring trust is less emphasized in standard patient-reported experience measures vis-à-vis more specific, tangible elements of care quality such as providing information.13 However, with evidence linking patient trust in the provider to treatment adherence and care continuity,14,15 more consistent measurement of it appears warranted. In primary care, there have been recent calls to employ more patient-centric measures as quality indicators, including patient experience measures that tap into feelings of trust and respect with providers.40 Organizational commitment to both measuring patient trust and supporting providers to pursue it could foster a health care climate where empathic care is considered normative.

Practical implications: teaching relational skills to healthcare providers

While medical education has paid somewhat more attention to improving communication through optimizing information provision, several studies indicate that interpersonal skills can also be effectively taught to physicians.41–43 A 2009 meta-analysis concluded that physician training in communication skills, including both task-oriented (eg, information provision) and psychosocial skills (eg, rapport and trust building), can result in substantial improvements in patient adherence to treatment.8 Further evidence suggests that building an atmosphere of trust and nonjudgmental acceptance within the medical encounter may facilitate more open and honest discussions between providers and patients about self-care.19 While many studies have focused on training physicians, enhancing communication and relational skills in other healthcare providers could have important implications as well. Studies have shown that patients are more adherent to treatment plans and more satisfied with their care when they interact with nurse practitioners who have a “biopsychosocial” style of communication – communication that actively engages patients in decisions about their care and takes into account their socioemotional environment.44 Furthermore, communication skills training may be useful for clinical pharmacists. Recent evidence suggests that clinical pharmacists focus largely on biomedical issues in their encounters with patients and pay little attention to psychosocial issues, including those that may affect medication adherence.45,46 Given the importance of multidisciplinary care teams in the management of patients with chronic illnesses,47 optimal patient outcomes are more likely to be realized when all members of the clinical care team are proficient in patient-centered communication.

Limitations

First, our study’s cross-sectional design precludes drawing causal conclusions about the effects of HPRQ. It is possible that patients more adept at self-management and lower in distress are simply easier for providers to relate to and work with, leading to more favorable impressions by the patients. Second, most of the data for this analysis relied on patient self-reports. More objective outcomes extracted from patient medical records or administrative claims could be used in future studies to further clarify the role of HPRQ in patient outcome. In particular, self-reporting of medication adherence is more accurately construed as assessing perceived, rather than actual adherence. The single-item measure used in this study lacks comprehensiveness48 and may be subject to social desirability bias (ie, skewed toward greater reporting of adherence). Hence, actual group differences in HPRQ across medication adherence may be larger than what was observed in this study. Socially desirable responding in the HPRQ measure (ie, toward higher rating of provider relational quality) could also have attenuated some of the correlations with the other outcome measures due to restricted range in the scores. Third, our measure of HPRQ was intentionally brief and reflected issues voiced in interviews and focus groups of a select sample of patients with MCCs. As the parent study was focused on deriving and testing a multi-domain measure of treatment and self-management burden,3 we were less interested in simultaneously developing a comprehensive measure of HPRQ. Hence, there may be some important aspects of this concept that are missing from our scale. Still, we believe that valuable lessons can be learned from even very brief measures of potential mitigating influences of treatment and self-management burden. Future research that compares various resources that patients may draw on to relieve burden or that investigates the impact of multiple accumulated resources is rendered more feasible when measurements of diverse constructs are targeted and brief. Finally, as the HPRQ scale did not specify a particular provider or provider type, we do not know which provider (or providers) the patient was referencing when rating the items. We only know that they were thinking of those health professionals who were currently providing them with medical care for their health conditions.

Conclusion

Our study augments the growing body of evidence that relational skills of healthcare providers may influence the ability of chronically ill patients to self-manage their conditions. Not only do good communication and interpersonal skills of providers appear to be important, but so too does the degree of trust that patients have in their providers. Our data suggest that a simple assessment of patient trust could augment traditional patient experience measures of the patient–provider relationship. Future research should prospectively test the influence of HPRQ on self-management outcomes like treatment burden, as well as compare the effects of HPRQ to other resources that patients may draw on to help manage their health (eg, individual coping ability, support from caregivers, etc). Our findings and those of others indicate that the quality of the patient–provider relationship does seem to matter. Future investigation should focus on the extent to which it does.
