Patients' participation in medical care: effects on blood sugar control and quality of life in diabetes

To maximize disease control, patients must participate effectively in their medical care. The authors developed an intervention designed to increase the involvement of patients in medical decision making. In a 20-minute session just before the regular visit to a physician, a clinic assistant reviewed the medical record of each experimental patient with him/her, guided by a diabetes algorithm. Using systematic prompts, the assistant encouraged patients to use the information gained to negotiate medical decisions with the doctor. A randomized trial was conducted in two university hospital clinics to compare this intervention with standard educational materials in sessions of equal length. The mean pre-intervention glycosylated hemoglobin (HbA1) values were 10.6±2.1% for 33 experimental patients and 10.3±2.0% for 26 controls. After the intervention the mean levels were 9.1±1.9% in the experimental group (p<0.01) and 10.6±2.22% for controls. Analysis of audiotapes of the visits to the physician showed the experimental patients were twice as effective as controls in eliciting information from the physician. Experimental patients reported significantly fewer function limitations. The authors conclude that the intervention is feasible and that it changes patient behavior, improves blood sugar control, and decreases functional limitations.

Better physician-patient relationships are associated with higher reported adherence to antiretroviral therapy in patients with HIV infection

AbstractBACKGROUND: There is little evidence to support the widely accepted assertion that better physician-patient relationships result in higher rates of adherence with recommended therapies. OBJECTIVE: To determine whether and which aspects of a better physician-patient relationship are associated with higher rates of adherence with antiretroviral therapies for persons with HIV infection. DESIGN: Cross-sectional analysis. SETTING: Twenty-two outpatient HIV practices in a metropolitan area. PARTICIPANTS: Five hundred fifty-four patients with HIV infection taking antiretroviral medications. MEASUREMENTS: We measured adherence using a 4-item self-report scale (α=0.75). We measured core aspects of physician-patient relationships using 6 previously tested scales (general communication, HIV-specific information, participatory decision making, overall satisfaction, willingness to recommend physician, and physician trust; α>0.70 for all) and 1 new scale, adherence dialogue (α=0.92). For adherence dialogue, patients rated their physician at understanding and solving problems with antiretroviral therapy regimens. RESULTS: Mean patient age was 42 years, 15% were female, 73% were white, and 57% reported gay or bisexual sexual contact as their primary HIV risk factor. In multivariable models that accounted for the clustering of patients within physicians’ practices, 6 of the 7 physician-patient relationship quality variables were significantly (P<.05) associated with adherence. In all 7 models worse adherence was independently associated (P<.05) with lower age, not believing in the importance of antiretroviral therapy, and worse mental health. CONCLUSIONS: This study showed that multiple, mutable dimensions of the physician-patient relationship were associated with medication adherence in persons with HIV infection, suggesting that physician-patient relationship quality is a potentially important point of intervention to improve patients’ medication adherence. In addition, our data suggest that it is critical to investigate and incorporate patients’ belief systems about antiretroviral therapy into adherence discussions, and to identify and treat mental disorders.

Providing High-Quality Care for Limited English Proficient Patients: The Importance of Language Concordance and Interpreter Use

BackgroundProvider–patient language discordance is related to worse quality care for limited English proficient (LEP) patients who speak Spanish. However, little is known about language barriers among LEP Asian-American patients.ObjectiveWe examined the effects of language discordance on the degree of health education and the quality of interpersonal care that patients received, and examined its effect on patient satisfaction. We also evaluated how the presence/absence of a clinic interpreter affected these outcomes.DesignCross-sectional survey, response rate 74%.ParticipantsA total of 2,746 Chinese and Vietnamese patients receiving care at 11 health centers in 8 cities.MeasurementsProvider–patient language concordance, health education received, quality of interpersonal care, patient ratings of providers, and the presence/absence of a clinic interpreter. Regression analyses were used to adjust for potential confounding.ResultsPatients with language-discordant providers reported receiving less health education (β = 0.17, p < 0.05) compared to those with language-concordant providers. This effect was mitigated with the use of a clinic interpreter. Patients with language-discordant providers also reported worse interpersonal care (β = 0.28, p < 0.05), and were more likely to give low ratings to their providers (odds ratio [OR] = 1.61; CI = 0.97–2.67). Using a clinic interpreter did not mitigate these effects and in fact exacerbated disparities in patients’ perceptions of their providers.ConclusionLanguage barriers are associated with less health education, worse interpersonal care, and lower patient satisfaction. Having access to a clinic interpreter can facilitate the transmission of health education. However, in terms of patients’ ratings of their providers and the quality of interpersonal care, having an interpreter present does not serve as a substitute for language concordance between patient and provider.

Individualized Patient Education and Coaching to Improve Pain Control Among Cancer Outpatients

PURPOSE An estimated 42% of cancer patients suffer from poorly controlled pain, in part because of patient-related barriers to pain control. The objective of this study was to evaluate the effect of an individualized education and coaching intervention on pain outcomes and pain-related knowledge among outpatients with cancer-related pain. PATIENTS AND METHODS English-speaking cancer patients (18 to 75 years old) with moderate pain over the past 2 weeks were randomly assigned to the experimental (n = 34) or control group (n = 33). Experimental patients received a 20-minute individualized education and coaching session to increase knowledge of pain self-management, to redress personal misconceptions about pain treatment, and to rehearse an individually scripted patient-physician dialog about pain control. The control group received standardized instruction on controlling pain. Data on average pain, functional impairment as a result of pain, pain frequency, and pain-related knowledge were collected at enrollment and 2-week follow-up. RESULTS At baseline, there were no significant differences between experimental and control groups in terms of average pain, functional impairment as a result of pain, pain frequency, or pain-related knowledge. At follow-up, average pain severity improved significantly more among experimental group patients than among control patients (P =.014). The intervention had no statistically significant impact on functional impairment as a result of pain, pain frequency, or pain-related knowledge. CONCLUSION Compared with provision of standard educational materials and counseling, a brief individualized education and coaching intervention for outpatients with cancer-related pain was associated with improvement in average pain levels. Larger studies are needed to validate these effects and elucidate their mechanisms.

Sex Differences in Academic Advancement — Results of a National Study of Pediatricians

BACKGROUND Although the numbers of women in training and in entry-level academic positions in medicine have increased substantially in recent years, the proportion of women in senior faculty positions has not changed. We conducted a study to determine the contributions of background and training, academic productivity, distribution of work time, institutional support, career attitudes, and family responsibilities to sex differences in academic rank and salary among faculty members of academic pediatric departments. METHODS We conducted a cross-sectional survey of all salaried physicians in 126 academic departments of pediatrics in the United States in January 1992. Of the 6441 questionnaires distributed, 4285 (67 percent) were returned. The sample was representative of U.S. pediatric faculty members. Multivariate models were used to relate academic rank and salary to 16 independent variables. RESULTS Significantly fewer women than men achieved the rank of associate professor or higher. For both men and women, higher salaries and ranks were related to greater academic productivity (more publications and grants), more hours worked, more institutional support of research, greater overall career satisfaction, and fewer career problems. Less time spent in teaching and patient care was related to greater academic productivity for both sexes. Women in the low ranks were less academically productive and spent significantly more time in teaching and patient care than men in those ranks. Adjustment for all independent variables eliminated sex differences in academic rank but not in salary. CONCLUSIONS Lower rates of academic productivity, more time spent in teaching and patient care and less time spent in research, less institutional support for research, and lower rates of specialization in highly paid subspecialties contributed to the lower ranks and salaries of female faculty members.

Effectiveness of remote patient monitoring after discharge of hospitalized patients with heart failure the better effectiveness after transition-heart failure (BEAT-HF) randomized clinical trial

IMPORTANCE It remains unclear whether telemonitoring approaches provide benefits for patients with heart failure (HF) after hospitalization. OBJECTIVE To evaluate the effectiveness of a care transition intervention using remote patient monitoring in reducing 180-day all-cause readmissions among a broad population of older adults hospitalized with HF. DESIGN, SETTING, AND PARTICIPANTS We randomized 1437 patients hospitalized for HF between October 12, 2011, and September 30, 2013, to the intervention arm (715 patients) or to the usual care arm (722 patients) of the Better Effectiveness After Transition-Heart Failure (BEAT-HF) study and observed them for 180 days. The dates of our study analysis were March 30, 2014, to October 1, 2015. The setting was 6 academic medical centers in California. Participants were hospitalized individuals 50 years or older who received active treatment for decompensated HF. INTERVENTIONS The intervention combined health coaching telephone calls and telemonitoring. Telemonitoring used electronic equipment that collected daily information about blood pressure, heart rate, symptoms, and weight. Centralized registered nurses conducted telemonitoring reviews, protocolized actions, and telephone calls. MAIN OUTCOMES AND MEASURES The primary outcome was readmission for any cause within 180 days after discharge. Secondary outcomes were all-cause readmission within 30 days, all-cause mortality at 30 and 180 days, and quality of life at 30 and 180 days. RESULTS Among 1437 participants, the median age was 73 years. Overall, 46.2% (664 of 1437) were female, and 22.0% (316 of 1437) were African American. The intervention and usual care groups did not differ significantly in readmissions for any cause 180 days after discharge, which occurred in 50.8% (363 of 715) and 49.2% (355 of 722) of patients, respectively (adjusted hazard ratio, 1.03; 95% CI, 0.88-1.20; P = .74). In secondary analyses, there were no significant differences in 30-day readmission or 180-day mortality, but there was a significant difference in 180-day quality of life between the intervention and usual care groups. No adverse events were reported. CONCLUSIONS AND RELEVANCE Among patients hospitalized for HF, combined health coaching telephone calls and telemonitoring did not reduce 180-day readmissions.

Metabolic Control and Prevalent Cardiovascular Disease in Non-Insulin-dependent Diabetes Mellitus (NIDDM): The NIDDM Patient Outcomes Research Team

PURPOSE Cardiovascular disease is a major cause of morbidity and death in non-insulin-dependent diabetes mellitus (NIDDM). While hyperglycemia is clearly related to diabetic microvascular complications, it contribution to large-vessel atherosclerosis is controversial. PATIENTS AND METHODS We performed an analysis of the association between glycemic control and prevalent cardiovascular disease in 1,539 participants in the NIDDM Patient Outcomes Research Team study who were under usual care in a health maintenance organization. Prevalent cardiovascular disease and its risk factors were identified by self-administered questionnaire. Cardiovascular disease was defined by the presence of coronary heart disease, peripheral vascular disease, and/or cerebrovascular disease. Glycohemoglobin and lipid levels were obtained from a computerized laboratory database. RESULTS The mean age of participants was 63 years (range 31 to 91); 51% were women. The mean duration of NIDDM was 9 years (range < 1 to 50), 35% took insulin, and 48% took sulfonylureas. Mean glycohemoglobin was 10.6%. Sixty percent had hypertension, 16% currently smoked cigarettes, and the mean total high-density lipoprotein (HDL) cholesterol ratio was 5.7. Fifty-one percent had cardiovascular disease. Cardiovascular disease prevalence remained constant across increasing quartiles of glycohemoglobin for both men and women. In contrast, prevalent cardiovascular disease was associated with established cardiovascular disease risk factors including age (67 versus 59 years, P < 0.0001), hypertension (66% versus 54%, P < 0.0001), current cigarette smoking (17% versus 13%, P < 0.005), and total/HDL cholesterol ratio (5.9 versus 5.6, P < 0.005). Cardiovascular disease was also associated with duration of NIDDM (11 versus 8 years, P < 0.0001). In multiple logistic regression analysis controlling for established cardiovascular disease risk factors and diabetes duration and therapy, glycohemoglobin remained unassociated with cardiovascular disease. CONCLUSIONS Glycemic control is not associated with prevalent cardiovascular disease in this large population of individuals with NIDDM. Conventional cardiovascular disease risk factors are independently associated with cardiovascular disease and be a more promising focus for clinical intervention to reduce atherosclerotic complications in NIDDM.

Assessment of prognosis with the total illness burden index for prostate cancer: aiding clinicians in treatment choice.

Among the most pressing challenges that face physicians who care for men with prostate cancer is evaluating the patients potential for benefiting from treatment. Because prostate cancer often follows an indolent course, the presence and severity of comorbidities may influence the decision to treat the patient aggressively. The authors adapted the Total Illness Burden Index (TIBI) for use in decision‐making among men with prostate cancer at the time of the visit.

Patient reports of health status as predictors of physiologic health measures in chronic disease

Accurate assessment of health status and forecasting of risk for poor outcomes in chronic disease require a broad representation of health measures. To support this conclusion, the health of patients with diabetes (N = 73) and hypertension (N = 105) was assessed using measures of physical and role functioning, perceived health, and disease severity (blood sugar or diastolic blood pressure, respectively, for diabetes and hypertension). Health questionnaires measuring functional limitations, overall health rating, level of health concern, perceived susceptibility to illness, and number of health problems were administered at study enrollment. Laboratory tests for blood sugar (hemoglobin A1) and diastolic blood pressures were performed at enrollment and were repeated at a subsequent clinic visit, from 3 to 6 months later. Functional limitations correlated significantly with elevated blood sugar (r = 0.57) and blood pressure (r = 0.49) at study enrollment. Perceived poor health was not substantially related to either physiologic measure at enrollment. Using ordinary least squares regression, the best predictor of both blood sugar and blood pressure at follow-up was baseline blood sugar and blood pressure, respectively. However, both functional limitations and perceived poor health made significant and independent contributions to the prediction of blood sugar and blood pressure at follow-up. The results underscore the value of both health survey measures and clinical measures in studies of chronic disease.

Self-monitoring of blood glucose in non-insulin-treated diabetic patients: a longitudinal evaluation of its impact on metabolic control

Aims  In the framework of a nationwide outcomes research programme, we assessed the impact of self‐monitoring of blood glucose (SMBG) on metabolic control over 3 years in patients with Type 2 diabetes mellitus (DM2) not treated with insulin.
