A novel analytical strategy for patient–physician communication research: The one-with-many design

Objective

We aimed to demonstrate how a novel analytic strategy – the one-with-many (OWM) design – can provide unique information about patient–physician communication that cannot be obtained using traditional analytic strategies.

Methods

Using an OWM design we conducted a secondary analysis of behavioral (talk time) and self-reported (perceived teamness) data from a study of patient–physician communication, and examined variance decompositions of these variables.

Results

Talk time was largely relational, suggesting that there is no behavioral consistency on the part of physicians across patients or behavioral similarity among patients who see the same physician. In contrast, there was significant actor variance in perceived teamness, suggesting that some physicians consistently reported higher teamness with their patients than others. However, those physicians’ positive perceptions of the communication are not necessarily reciprocated by their patients.

Conclusions

OWM design provides researchers with the opportunity to take full advantage of rich non-independent data and explore interesting communication patterns (e.g., behavioral continuity, similarity, reciprocity unique to specific dyads) that have been omitted in prior literature.

Practical implications

OWM can be used to determine the relative differences in how patients and physicians influence communication patterns and identify which aspects of physician–patient communication are relational and which are not.     

Adherence of Randomized Controlled Trials to Consolidated Standards of Reporting Trials 2010 Guidelines: A Survey of Randomized Controlled Trials Published in 2011-2016 in 3 Periodontology Journals

ObjectiveTo assess the quality of reporting of randomized controlled trials (RCTs) in the Journal of Clinical Periodontology (JCP), Journal of Periodontology (JOP), and Journal of Periodontal Research (JPR), published in the years 2011 until 2016, using Consolidated Standards of Reporting Trials (CONSORT) 2010 guidelines.MethodsA thorough search of PubMed for RCTs published between January 2011 and December 2016 in the three journals was carried out. The CONSORT 2010 checklist (36 questions) was used to evaluate the adherence of these RCTs to these guidelines. A modified CONSORT score was calculated and categorized as “perfect” (100%), “excellent” (80%-99%), “good” (60%-79%), “modest” (40%-59%), and “poor” (<40%).ResultsA total of 369 RCTs were published in the three periodontology journals from 2011 until 2016. Based on the modified CONSORT score among all the RCTs, title, abstract, and introduction sections of the included RCTs showed good adherence to the CONSORT 2010 guidelines (60%-79%), whereas the adherence was poor for half the items in methodology (<40%), results (<40%), and discussion (40%). The highest modified CONSORT score was obtained for the trials published in the JCP from 2011 to 2016, whereas the lowest score was achieved by the RCTs in the JPR. Overall, none of the RCTs in any of the journals were perfect in reporting the trials as per the guidelines. Almost half of the RCTs in the JCP showed good adherence (51.1%), whereas almost three-fourths of the RCTs in the JOP (72%) and JPR (82.7%) showed modest to poor adherence as per the reporting guidelines (P < .001).ConclusionAmong the three periodontology journals assessed, the JCP showed better adherence than the JOP and JPR from 2011 until 2016.     

Lifestyle Modification for Metabolic Syndrome: A Systematic Review

Background

All 5 components of metabolic syndrome have been shown to improve with lifestyle and diet modification. New strategies for achieving adherence to meaningful lifestyle change are needed to optimize atherosclerotic cardiovascular risk reduction. We performed a systematic literature review, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework (PRISMA), investigating optimal methods for achieving lifestyle change in metabolic syndrome.

Methods

We submitted standardized search terms to the PubMed Central, CINAHL, Web of Science, and Ovid databases. Within those results, we selected randomized controlled trials (RCTs) presenting unique methods of achieving lifestyle change in patients with one or more components of the metabolic syndrome. Data extraction using the population, intervention, comparator, outcome, and risk of bias framework (PICO) was used to compare the following endpoints: prevalence of metabolic syndrome, prevalence of individual metabolic syndrome components, mean number of metabolic syndrome components, and amount of weight loss achieved.

Results

Twenty-eight RCTs (6372 patients) were included. Eight RCTs demonstrated improvement in metabolic syndrome risk factors after 1 year. Team-based, interactive approaches with high-frequency contact with patients who are motivated made the largest and most lasting impact. Technology was found to be a useful tool in achieving lifestyle change, but ineffective when compared with personal contact.

Conclusion

Patient motivation leading to improved lifestyle adherence is a key factor in achieving reduction in metabolic syndrome components. These elements can be enhanced via frequent encounters with the health care system. Use of technologies such as mobile and Internet-based communication can increase the effectiveness of lifestyle change in metabolic syndrome, but should not replace personal contact as the cornerstone of therapy. Our ability to derive quantitative conclusions is limited by inconsistent outcome measures across studies, low power and homogeneity of individual studies, largely motivated study populations, short follow-up periods, loss to follow-up, and lack of or incomplete blinding.     

FACTORS ASSOCIATED TO ADHERENCE TO DIFFERENT TREATMENT SCHEMES WITH MEGLUMINE ANTIMONIATE IN A CLINICAL TRIAL FOR CUTANEOUS LEISHMANIASIS

The favorable outcome of the treatment of a disease is influenced by the adherence to therapy. Our objective was to assess factors associated with adherence to treatment of patients included in a clinical trial of equivalence between the standard and alternative treatment schemes with meglumine antimoniate (MA) in the treatment of cutaneous leishmaniasis (CL), in the state of Rio de Janeiro. Between 2008 and 2011, 57 patients with CL were interviewed using a questionnaire to collect socioeconomic data. The following methods were used for adherence monitoring: counting of vial surplus, monitoring card, Morisky test and modified Morisky test (without the question regarding the schedule); we observed 82.1% (vial return), 86.0% (monitoring card), 66.7% (Morisky test) and 86.0% (modified Morisky test) adherence. There was a strong correlation between the method of vial counting and the monitoring card and modified Morisky test. A significant association was observed between greater adherence to treatment and low dose of MA, as well as with a lower number of people sleeping in the same room. We recommend the use of the modified Morisky test to assess adherence to treatment of CL with MA, because it is a simple method and with a good performance, when compared to other methods.     

Nonadherence to treatment causing acute hospitalizations in people with epilepsy: An observational,prospective study

The aim was to assess the clinical relevance of antiepileptic drug (AED) nonadherence by means of therapeutic drug concentration monitoring (TDM). Two hundred eighty‐two consecutive patients with epilepsy acutely admitted to hospital for seizures were included. Nonadherence was defined as having a serum concentration/dose ratio at admission of <75% of the patient's own control value (probable nonadherence: 50–75%; definite: <50%). Nonadherence was identified in 39% of patients (definite 24%; probable 15%). It was significantly more common in patients with generalized seizures compared to those with focal onset seizures, and in patients <30 years compared to older patients. When specifically asked, 44% of nonadherent patients claimed regular intake. Nonadherence is a major cause of seizure breakthrough in patients with epilepsy, particularly in young adults. Many patients seem to be unaware of missed drug intake. Prompt measurements of AED serum concentrations should be available as part of the emergency care for patients acutely hospitalized for seizures to permit this issue to be thoroughly addressed prior to discharge.     

Partial compliance with antipsychotics and its impact on patient outcomes

Partial compliance with antipsychotic medications is a common and complex phenomenon that is underestimated by physicians. The consequences of partial compliance include an increased risk of relapse, rehospitalization and suicide attempts. Stigma, negative attitudes towards medications, cognitive impairment and diminished insight negatively impact treatment adherence. Oral atypical antipsychotics may improve both insight and cognitive function, but compliance with these agents is not assured. Depot conventional antipsychotics ensure medication delivery but are associated with side-effects such as EPS and dysphoria that decrease compliance. Long-acting atypicals provide significant symptom improvement, foster adherence and may help achieve improvement in insight and cognition. Addressing issues of partial and non-compliance is a significant consideration in relapse prevention strategies for patients with schizophrenia, given the devastating consequences associated with psychotic relapses.     

HIV-Associated Prospective Memory Impairment in the Laboratory Predicts Failures on a Semi-Naturalistic Measure of Health Care Compliance

HIV-associated neurocognitive impairment, particularly in the domain of prospective memory (ProM), increases the risk of poor everyday functioning outcomes, including medication non-adherence. However, whether ProM plays a role in health care compliance outside of the realm of medication adherence remains to be determined. This study evaluated the hypothesis that ProM is an independent predictor of failure to comply with non-medication-related instructions akin to those commonly given by health care providers. Participants were 139 HIV-infected adults who underwent medical, psychiatric, and neuropsychological assessments, including a laboratory-based measure of ProM. To assess real-world compliance, participants were instructed to call the examiner 24 hours after the evaluation and report how many hours they had slept. Individuals who failed to correctly comply with these instructions (n = 104) demonstrated significantly lower performance on both time- and event-based ProM at baseline than the compliant group (n = 35), an effect that was primarily driven by errors of omission. ProM remained a significant predictor of noncompliance after controlling for potential confounders, including demographics (e.g., education), traditional cognitive measures of retrospective memory and executive functions, and psychiatric factors (e.g., depression). Results support the hypothesis that ProM plays a unique role in compliance with health care instructions for HIV disease management and may inform interventions designed to improve treatment outcomes.      

Positive impact of hepatitis C virus (HCV) treatment on antiretroviral treatment adherence in human immunodeficiency virus-HCV coinfected patients: one more argument for expanded access to HCV treatment for injecting drug users

Aims Treatment for the hepatitis C virus (HCV) may be delayed significantly in human immunodeficiency virus (HIV)/HCV coinfected patients on antiretroviral treatment (ART) for fear that its burden could compromise ART adherence. However, the effect such treatment has on ART adherence in observational settings remains largely unknown. Longitudinal data were used to investigate the relationship between initiating HCV treatment and adherence to ART in HIV/HCV coinfected patients. Design The French national prospective cohort of patients coinfected with HIV and HCV (ANRS‐CO‐13‐HEPAVIH) is a multi‐centre cohort. Setting Seventeen out‐patient hospital services delivering HIV and HCV care in France. Participants HIV/HCV coinfected patients on ART (n = 593 patients, 976 visits). Measurements Self‐administered questionnaires and medical records. A mixed logistic regression model based on generalized estimates equations (GEE) to identify factors associated with non‐adherence to ART. Findings Among the 593 patients, 36% were classified as non‐adherent to ART at the enrolment visit and 12% started HCV treatment during follow‐up. ART adherence was not associated statistically with HCV treatment initiation. The proportion of patients maintaining adherence or becoming adherent to ART for those starting HCV treatment was higher than in the rest of the sample (P = 0.07). After multiple adjustment for known correlates, such as poor housing conditions, binge drinking, recent drug use and depressive symptoms, patients who initiated HCV treatment were less likely to be non‐adherent to ART [odds ratio (95% confidence interval) = 0.41 (0.24–0.71)]. Conclusions Engaging human immunodeficiency virus/hepatitis C virus coinfected individuals in hepatitis C virus treatment is associated with high adherence to antiretroviral treatment. Physicians should prioritize hepatitis C virus treatment as part of a multi‐disciplinary approach.     

Safety and predictors of adherence of a new rehabilitation program for older women with congestive heart failure

Objectives To assess the safety of a cardiac rehabilitation program for older women with Congestive Heart Failure (CHF) and determine if certain factors influence adherence. Methods Women over the age of 65 with CHF attended an exercise program supervised by a physiotherapist. Quality of life was measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and severity of disease by the New York Heart Association (NYHA) Class. Subjects were classified into those who attended 90% or more of the sessions and those who attended less than 90% of the sessions. Results Fifty-one subjects were studied. Eight subjects did not attend any sessions. Of the 43 attendees, the average percentage of sessions attended was 87%. There were no significant differences between the two groups in age, MLHFQ or NYHA Class. There was only one adverse event out of 280 participant attendances. Conclusions The program had a high level of adherence in this population. Age, MLHFQ or NYHA Class did not impact on session attendance. Our data suggests this program is safe for this population. Further research is needed to determine other predictors of attendance and the examination of safety issues and long-term adherence to exercise in this population.
