Communication and culture: predictors of treatment adherence among Mexican immigrant patients

This study examined communication and culture in clinicians' interactions with Mexican immigrants in Texas. Specifically, we explore the unique interplay among levels of acculturation, beliefs about culturally-based medical practices, perceptions of medical encounters, and the likelihood of adherence to medical therapy recommendations from US providers. Results suggest that: (a) acculturation predicts perceptions of out-group membership in the patient-provider interaction; (b) beliefs about complementary and alternative medicine are negatively related to medical adherence; (c) quality of care mediates the relationship between physician accommodation and medical adherence; and (d) there exists a complex relationship between out-group perceptions and adherence.     

Antecedents of adherence to medical recommendations: Results from the medical outcomes study

A longitudinal study of patients with chronic medical diseases (hypertension, diabetes, heart disease) was conducted to identify antecedents of adherence to medical recommendations. Data are from 1198 patients in three health-care provision systems in Los Angeles, Chicago, and Boston. Nonadherence at the beginning of the study was the strongest predictor of nonadherence 2 years later. Other significant predictors varied by type of adherence outcome. Patients who were younger and who relied upon avoidant coping strategies tended to be less likely to follow their doctor's specific recommendations. Patients who were distressed about their health, used avoidant coping strategies, or who reported worse physical and role functioning were less likely to adhere in general. Patient satisfaction with two features of care (interpersonal quality and financial aspects) was positively related to adherence in some models, but satisfaction with the technical quality of care was negatively associated with adherence to specific recommendations among heart disease patients. Social support contributed to specific adherence among diabetic patients. Implications of the study for medical care providers are discussed.Supported by grants from the Agency for Health Care Policy and Research (Grant HS 06171), the National Institute on Aging, The Robert Wood Johnson Foundation, The Henry J.

Effect of a brief antiretroviral adherence intervention delivered by HIV care providers

Antiretroviral therapy (ART) is effective in controlling viral load in many people infected with HIV, but high levels of adherence to ART are needed for prolonged viral suppression. This study evaluated a brief adherence intervention delivered to HIV-positive patients by primary care providers during routine medical examinations. Six clinics were randomly allocated to deliver an intervention focusing on ART adherence (2 clinics) or safer sex (4 clinics). Interventions included written information (posters, brochures, and flyers) and brief counseling from providers and were evaluated with cohorts of randomly selected patients (n = 437) measured before and after a 10-month intervention. Among those 95% or greater adherent at baseline, 91% of patients who received the adherence intervention remained 95% or greater adherent at follow-up compared with 75% of the patients who received the safer sex intervention (chi = 12.59, P < 0.01). This difference was significant in a logistic regression analysis (odds ratio = 2.26; 95% confidence interval = 1.27-4.04), adjusting for baseline adherence, demographics, and HIV medical status. The adherence intervention did not significantly increase the prevalence of 95% or greater adherence among patients less than 95% adherent at baseline. Similar but nonsignificant results were observed for viral load. A brief intervention delivered to HIV patients by their primary providers helped to maintain adequate adherence to ART regimens. More intensive intervention is needed to improve adherence among patients who are initially less than 95% adherent.     

Timeliness of immunizations of children in a Medicaid primary care case management managed care program

OBJECTIVE: This study assessed the timeliness of immunization for children in a Medicaid managed care primary care case management program controlling for patient and provider predictors of immunization status. METHODS: Using administrative data and patient medical records, up-to-date (UTD) and age appropriate immunization (AAI) status were reviewed for 5598 children. The 4:3:1 immunization series (four diphtheria, pertussis, tetanus vaccinations; three polio vaccinations; and one measles, mumps, rubella vaccination) was the standard. RESULTS: Childhood immunization rates were low when assessed using strict adherence to vaccination recommendations. At age 18 months, 28.3% were classified as UTD, and 6.3% were classified as AAI. Compared to children not up-to-date, UTD children were more likely to have public rather than private providers, to have had older mothers, and less likely to have been African American. Among UTD children, AAI children were more likely to reside in urban areas. CONCLUSIONS: Low-income children continue to be under-immunized, even under a managed care initiative. Health care providers and child health advocates need to continue pressure for programs that will increase adherence to nationally recommended guidelines.     

Barriers to antiretroviral adherence for patients living with HIV infection and AIDS in Botswana

BACKGROUND: Botswana has the highest rate of HIV infection in the world, estimated at 36% among the population aged 15-49 years. To improve antiretroviral (ARV) treatment delivery, we conducted a cross-sectional study of the social, cultural, and structural determinants of treatment adherence. METHODS: We used both qualitative and quantitative research methodologies, including questionnaires and interviews with patients receiving ARV treatment and their health care providers to elicit principal barriers to adherence. Patient report and provider estimate of adherence (>/=95% doses) were the primary outcomes. RESULTS: One hundred nine patients and 60 health care providers were interviewed between January and July 2000; 54% of patients were adherent by self-report, while 56% were adherent by provider assessment. Observed agreement between patients and providers was 68%. Principal barriers to adherence included financial constraints (44%), stigma (15%), travel/migration (10%), and side effects (9%). On the basis of logistic regression, if cost were removed as a barrier, adherence is predicted to increase from 54% to 74%. CONCLUSIONS: ARV adherence rates in this study were comparable with those seen in developed countries. As elsewhere, health care providers in Botswana were often unable to identify which patients adhere to their ARV regimens. The cost of ARV therapy was the most significant barrier to adherence.     

Adherence issues in the medical management of asthma

Asthma is a common chronic illness of childhood that requires coordinated efforts by children, families, and health care professionals for proper medical management. The medical management of pediatric asthma involves pharmacological and behavioral recommendations to both prevent and control asthma attacks. However, management of these attacks is hindered by failure to adhere to the prescribed recommendations. While the literature on adherence in pediatric asthma has grown over the past 10 years, few definitive statements can be made about causes and treatment. Various issues related to adherence and pediatric asthma are reviewed in this paper, including assessment methods, factors influencing adherence, and treatment strategies. Recommendations for future research are provided, starting with more controlled randomized studies.     

Comorbidities and Challenges Affecting African Americans with HIV Infection

The significant disparities in health outcomes that exist among racial minorities in the United States are clearly evident in the HIV epidemic. HIV disproportionately affects minorities, African Americans in particular. Current treatment of HIV/AIDS is complicated by medical problems such as hepatitis, diabetes and dyslipidemia, which also disproportionately affect African Americans and can significantly impact the complexity of clinical care. In addition, untreated psychological problems such as depression and societal barriers to adequate medical care may decrease treatment adherence and increase HIV-related morbidity and mortality among African Americans. Consideration of these issues by healthcare providers is necessary to optimize care and improve treatment outcomes for African Americans with HIV infection.     

Physicians' communication of the common-sense self-regulation model results in greater reported adherence than physicians' use of interpersonal skills

Objectives. Interventions that address patients’ illness and treatment representations have improved patient adherence and outcomes when administered by psychologists and/or health educators and focused on a single chronic illness. The current study assesses the potential feasibility/effectiveness of an intervention based on the common‐sense self‐regulation model (CS‐SRM) when administered by providers in a primary care setting. Design. We designed a prospective, correlational study in order to optimize patients’ and providers’ time and to gain initial evidence of the CS‐SRM‐approach's feasibility/effectiveness. Methods. Patients (n= 243) were recruited from a primary care waiting room and reported on objective behaviours of their providers (providers’ CS‐SRM‐related behaviours and interpersonal skills) and other theoretically related measures directly after the medical encounter and reported on adherence, presenting problem resolution, and emergency care usage 1 month later. Results. The more providers gave their patients an adaptive understanding of their presenting problem/treatment (the greater the number of CS‐SRM‐related behaviours they engaged in), the more adherent were patients in the month following the encounter and the better was their problem resolution 1 month later. The CS‐SRM‐related behaviours were more predictive of these outcomes and emergency care usage than were the providers’ interpersonal skills. Conclusions. In the time‐limited encounter, interventions may have to prioritize theoretical approaches for attaining patient adherence. The current study, although correlational, indicates that addressing the patients’ illness/treatment representations is more important than the providers’ interpersonal skills for attaining patient adherence and provides preliminary evidence that a CSM‐based intervention in the primary care setting may be both feasible and effective.     

Determinants of adherence to medical regimens by hypertensive patients

This study employed multivariate analyses and structural modeling procedures to examine a model for the determinants of adherence to medical regimens. Fifty adult hypertensive patients at a health maintenance organization completed questionnaires and participated in home interviews over a 10-week period. Knowledge of medical regimens, information communication between the patient and the medical professionals, satisfaction with health-care providers, health locus of control, social support, and treatment disruption to life-style were assessed. Adherence was assessed through self-report and behavioral (i.e., pill-count ratio, percentage of kept medical appointments) indices. Finally, repeated blood-pressure measurements were obtained. Structural modeling procedures revealed that greater expectancy for internal control over health and hypertension, greater knowledge of the treatment regimen, and stronger social support were significant determinants of adherence; in turn, higher levels of adherence facilitated blood-pressure reduction.This article is based on the author's doctoral dissertation completed at the University of Connecticut and was supported in part by that institutions's Research Foundation.Portions of this work were presented at the annual meeting of the American Psychological Association, Los Angeles, 1983.     

Gynecologic cancer screening and communication with health care providers in women with Lynch syndrome

We evaluated knowledge of gynecologic cancer screening recommendations, screening behaviors, and communication with providers among women with Lynch syndrome (LS). Women aged ≥25 years who were at risk for LS‐associated cancers completed a semi‐structured interview and a questionnaire. Of 74 participants (mean age 40 years), 61% knew the appropriate age to begin screening, 75–80% correctly identified the recommended screening frequency, and 84% reported no previous screening endometrial biopsy. Women initiated discussions with their providers about their LS cancer risks, but many used nonspecific terms or relied on family history. Most were not offered high‐risk screening options. While many women were aware of risk‐appropriate LS screening guidelines, adherence was suboptimal. Improving communication between women and their providers regarding LS‐related gynecologic cancer risk and screening options may help improve adherence.     

Barriers to adherence to asthma management guidelines among inner-city primary care providers

BACKGROUND: Health care provider adherence to national asthma guidelines is critical in translating evidence-based recommendations into improved outcomes. Unfortunately, provider adherence to the National Heart, Lung, and Blood Institute (NHLBI) guidelines remains low. OBJECTIVE: To identify barriers to guideline adherence among primary care professionals providing care to inner-city, minority patients with asthma. METHODS: We surveyed 202 providers from 4 major general medicine practices in East Harlem in New York, New York. The study outcome was self-reported adherence to 5 NHLBI guideline components: inhaled corticosteroid (ICS) use, peak flow (PF) monitoring, action plan use, allergy testing, and influenza vaccination. Potential barriers included lack of agreement with guideline, lack of self-efficacy, lack of outcome expectancy, and external barriers. RESULTS: Most providers reported adhering to the NHLBI guidelines for ICS use (62%) and for influenza vaccinations (73%). Self-reported adherence was 34% for PF monitoring, 9% for asthma action plan use, and 10% for allergy testing. Multivariate analyses showed that self-efficacy was associated with increased adherence to ICS use (odds ratio [OR], 2.8; P = .03), PF monitoring (OR, 2.3; P = .05), action plan use (OR, 4.9; P = .03), and influenza vaccinations (OR, 3.5; P = .05). Conversely, greater expected patient adherence was associated with increased adherence to PF monitoring (OR, 3.3; P = .03) and influenza vaccination (OR, 3.5; P = .01). Familiarity with specific guideline components and higher level of training were also predictors of adherence. CONCLUSIONS: Lack of outcome expectancy and poor provider self-efficacy prevent providers from adhering to national asthma guidelines. Efforts to improve provider adherence should address these specific barriers.     

Substance Use: Impact on Adherence and HIV Medical Treatment

Substance use is highly prevalent among people living with HIV/AIDS, is often comorbid with other mental health problems, related to poor HIV medical outcomes, and, is associated with poor medication and treatment adherence. The current review reports on the recent state of the literature in terms of substance use and its relation to HIV medication and treatment adherence, and offers recommendations for advancing treatment and secondary HIV prevention efforts. Identifying substance users within HIV primary care and developing, evaluating, and refining integrative substance use-mental health-adherence interventions may be clinically important targets for effective disease management and may contribute to secondary HIV prevention efforts.     

Medical management adherence as an outcome of genetic counseling in a pediatric setting

PurposeWe sought to determine whether the inclusion of a genetic counselor in an initial pediatric genetics visit had an impact on patient adherence to management recommendations, as compared with initial visits in which only genetics physicians were involved.MethodsThis chart review included 198 pediatric patients seen for their initial visit to the general genetics clinic at the Cincinnati Children’s Hospital Medical Center in 2008. Ninety-eight patients were seen by one or more genetics physicians (the non–genetic counselor group), and 100 patients were seen by a geneticist and a genetic counselor (the genetic counselor group). Medical management recommendations and evidence of adherence to recommendations were abstracted from the medical record; adherence rates were compared between the genetic counselor and non–genetic counselor groups.ResultsAdherence was significantly associated with the inclusion of a genetic counselor (P = 0.009). Although type of management recommendation had a large impact on adherence, involvement of a genetic counselor significantly improved adherence in all three management recommendation categories.ConclusionInvolvement of a genetic counselor during an initial pediatric genetics visit may be associated with increased patient adherence. Further research is needed to determine whether this association applies in other genetic counseling settings and whether enhanced adherence results in improved medical outcomes.Genet Med16 2, 157–163.     

National Athletic Trainers' Association Position Statement: Exertional Heat Illnesses

OBJECTIVE: To present recommendations for the prevention, recognition, and treatment of exertional heat illnesses and to describe the relevant physiology of thermoregulation. BACKGROUND: Certified athletic trainers evaluate and treat heat-related injuries during athletic activity in "safe" and high-risk environments. While the recognition of heat illness has improved, the subtle signs and symptoms associated with heat illness are often overlooked, resulting in more serious problems for affected athletes. The recommendations presented here provide athletic trainers and allied health providers with an integrated scientific and practical approach to the prevention, recognition, and treatment of heat illnesses. These recommendations can be modified based on the environmental conditions of the site, the specific sport, and individual considerations to maximize safety and performance. RECOMMENDATIONS: Certified athletic trainers and other allied health providers should use these recommendations to establish on-site emergency plans for their venues and athletes. The primary goal of athlete safety is addressed through the prevention and recognition of heat-related illnesses and a well-developed plan to evaluate and treat affected athletes. Even with a heat-illness prevention plan that includes medical screening, acclimatization, conditioning, environmental monitoring, and suitable practice adjustments, heat illness can and does occur. Athletic trainers and other allied health providers must be prepared to respond in an expedient manner to alleviate symptoms and minimize morbidity and mortality.     

Race-based medical mistrust,medication beliefs and HIV treatment adherence: test of a mediation model in people living with HIV/AIDS

Race-based medical mistrust significantly predicts non-adherence to antiretroviral therapy (ART) in people living with HIV. The current study builds on previous research that shows beliefs about medication necessity (i.e., “My medicines protect me from becoming worse”) and concerns (i.e., “Having to take my medicines worries me”) mediate the association between race-based medical mistrust and medication adherence. Racial and ethnic minority men and women living with HIV and receiving ART (N = 178) in a southern US city completed computerized measures of demographic and health characteristics, telephone interviews of race-based medical mistrust and medication beliefs, and unannounced phone-based pill counts for ART adherence. Multiple mediation modeling showed that medical mistrust is related to medication necessity and concerns beliefs and ART adherence. Furthermore, medication necessity beliefs predicted ART adherence. The indirect effect of medical mistrust on adherence through medication necessity beliefs was also significant. Results confirm that medication necessity beliefs, although not concerns beliefs, mediate the association between medical mistrust and ART adherence. Medication necessity beliefs offer a viable target for interventions to improve ART adherence in the context of mistrust that patients may have for medical providers and health care systems.     

Highly active antiretroviral therapy adherence: the patient's point of view

There is a widespread acknowledgment that successful treatment with highly active antiretroviral therapy (HAART) requires the patient to maintain consistent adherence to the prescribed regimen on a long-term basis. Adherent patients have been shown to have reduced viral loads and increased CD4 counts, live longer, and have better quality-adjusted survival. The consequences of nonadherence are also obvious: poorer adherence leads to inadequate viral suppression and continued disease progression. With the astonishing advances in medical therapeutics during the past two decades, one may expect a similar proliferation of studies of the nature of nonadherence and tests of strategies to help patients overcome it. However, the literature and the know-how concerning interventions to improve adherence are still surprisingly weak. The unique challenges posed by combination therapies for HIV and AIDS require healthcare providers to address the issues created by adherence to complex regimens through multifactorial interventions tailored to patients' needs.     

Provider assessment of adherence to HIV antiretroviral therapy

BACKGROUND: Adherence assessment is an essential component of monitoring HIV antiretroviral therapy. Prior studies suggest that medical providers frequently estimate individual patient adherence inaccurately. OBJECTIVE: We compared provider estimates of nonadherence to antiretroviral therapy with unannounced pill counts and structured patient interviews to determine the accuracy of adherence information obtained by providers and patients. DESIGN, SETTING, AND PARTICIPANTS: Comparison of three adherence measures in homeless or marginally housed persons receiving HIV antiretroviral therapy (n = 45) and their providers (n = 35). MEASUREMENTS: Provider estimate of percentage of pills taken; three successive patient structured reports of number of doses missed in the last 3 days; and three successive unannounced pill counts. RESULTS: 13% (95% confidence interval [CI], 4%-22%) of patients were not following their regimen as directed. Provider-adherence estimate explained only 26% (95% CI, 6%-47%) of the variation in pill count adherence, whereas patient report explained 72% (95% CI, 52%-96%). The sensitivity and specificity of provider estimates of nonadherence, defined as <80% of pills taken by pill count, were 40% and 85%, respectively. The sensitivity and specificity of patient interview were 72% and 95%, respectively. CONCLUSIONS: Provider estimate of adherence was inaccurate whereas structured patient report was more closely related to pill count. Structured assessment over several short intervals may improve accuracy of adherence assessment in clinical practice.     

Psychiatric evaluations of heart transplant candidates: predicting post-transplant hospitalizations, rejection episodes, and survival

The authors assessed the validity of psychiatric evaluations for orthotopic heart transplant candidates with respect to predicting adverse post-transplant outcomes. A group of 108 transplant recipients were followed for an average of 970 days, and pre-transplant evaluations were retrospectively coded for psychiatric risk factors. Previous suicide attempts, poor adherence to medical recommendations, previous drug or alcohol rehabilitation, and depression significantly predicted attenuated survival times. Also, past suicide attempt was associated with a greater risk for post-transplant infection. Assessment and early treatment for these risk factors may reduce post-transplant morbidity and mortality.     

Does provider adherence to a treatment guideline change clinical outcomes for patients with bipolar disorder? Results from the Texas Medication Algorithm Project

BACKGROUND: Despite increasing adoption of clinical practice guidelines in psychiatry, there is little measurement of provider implementation of these recommendations, and the resulting impact on clinical outcomes. The current study describes one effort to measure these relationships in a cohort of public sector out-patients with bipolar disorder.METHOD:Participants were enrolled in the algorithm intervention of the Texas Medication Algorithm Project (TMAP). Study methods and the adherence scoring algorithm have been described elsewhere. The current paper addresses the relationships between patient characteristics, provider experience with the algorithm, provider adherence, and clinical outcomes. Measurement of provider adherence includes evaluation of visit frequency, medication choice and dosing, and response to patient symptoms. An exploratory composite 'adherence by visit' score was developed for these analyses.RESULTS: A total of 1948 visits from 141 subjects were evaluated, and utilized a two-stage declining effects model. Providers with more experience using the algorithm tended to adhere less to treatment recommendations. Few patient factors significantly impacted provider adherence. Increased adherence to algorithm recommendations was associated with larger decreases in overall psychiatric symptoms and depressive symptoms over time, but did not impact either immediate or long-term reductions in manic symptoms.CONCLUSIONS: Greater provider adherence to treatment guideline recommendations was associated with greater reductions in depressive symptoms and overall psychiatric symptoms over time. Additional research is needed to refine measurement and to further clarify these relationships.     

Adapted motivational interviewing for brief healthcare consultations: A systematic review and meta-analysis of treatment fidelity in real-world evaluations of behaviour change counselling

Background

Behaviour change counselling (BCC) is an adaptation of motivational interviewing (MI) designed to maximize the effectiveness of time-limited health behaviour change consultations. To improve intervention quality and understanding of treatment effects, it is recommended that evaluations of health behaviour change interventions incorporate existing fidelity frameworks (e.g. The National Institutes of Health [NIH] Behaviour Change Consortium) and ensure that treatment fidelity is assessed and reported.

Purpose

This systematic review was designed to examine (a) adherence to NIH fidelity recommendations, (b) provider fidelity to BCC and (c) impact of these variables on the real-world effectiveness of BCC for adult health behaviours and outcomes.

Methods and Results

Searches of 10 electronic databases yielded 110 eligible publications describing 58 unique studies examining BCC delivered within real-world healthcare settings by existing providers. Mean study adherence to NIH fidelity recommendations was 63.31% (Range 26.83%–96.23%). Pooled effect size (Hedges g) for short-term and long-term outcomes was .19 (95% CI [.11, .27]) and .09 (95% CI [.04, .13]), respectively. In separate, random-effects meta-regressions, neither short-term nor long-term effect sizes were significantly modified by adherence to NIH fidelity recommendations. For the subgroup of short-term alcohol studies (n = 10), a significant inverse relationship was detected (Coefficient = −.0114, 95% CI [−.0187, −.0041], p = .0021). Inadequate and inconsistent reporting within the included studies precluded planned meta-regression between provider fidelity and BCC effect size.

Conclusions

Further evidence is needed to clarify whether adherence to fidelity recommendations modifies intervention effects. Efforts to promote transparent consideration, evaluation and reporting of fidelity are urgently needed. Research and clinical implications are discussed.
