Differences in medication adherence by sex and organ type among adolescent and young adult solid organ transplant recipients.

BACKGROUND: Identification of differences in medication adherence by sex or organ type may help in planning interventions to optimize outcomes. We compared immunosuppressive medication adherence between males and females, and between kidney, liver and heart transplant recipients. METHODS: This multicenter study of prevalent kidney, liver and heart transplant recipients 14-25 years assessed adherence 3 times (0, 3, 6 months post-enrollment) with the BAASIS self-report tool. At each visit, participants were classified as adherent if they missed no doses in the prior 4 weeks and non-adherent otherwise. Adherence was also assessed using the coefficient of variation (CV) of tacrolimus trough levels; CV < 30% was classified as adherent. We used multivariable mixed effects logistic regression models adjusted for potential confounders to compare adherence by sex and by organ. RESULTS: Across all visits, males (n = 150, median age 20.4 years, IQR 17.2-23.3) had lower odds of self-reported adherence than females (n = 120, median age 19.8 years, IQR 17.1-22.7) (OR 0.41, 95% CI 0.21-0.80) but higher odds of adherence by tacrolimus CV (OR 2.50, 95% CI 1.30-4.82). No significant differences in adherence (by self-report or tacrolimus CV) were noted between the 184 kidney, 58 liver, and 28 heart recipients. CONCLUSION: Females show better self-reported adherence than males but greater variability in tacrolimus levels. Social desirability bias, more common in females than males, may contribute to better self-reported adherence among females. Higher tacrolimus variability among females may reflect biologic differences in tacrolimus metabolism between males and females rather than sex differences in adherence. There were no significant differences in adherence by organ type.

Care processes and structures associated with higher medication adherence in adolescent and young adult transplant recipients.

BACKGROUND: We aimed to identify care processes and structures that were independently associated with higher medication adherence among young transplant recipients. METHODS: We conducted a prospective, observational cohort study of 270 prevalent kidney, liver, and heart transplant recipients 14-25 years old. Patients were ≥3 months post-transplant, ≥2 months post-discharge, and followed in one of 14 pediatric or 14 adult transplant programs in Canada. Patients were enrolled between June 2015 and March 2018 and followed for 6 months. Adherence was assessed at baseline, 3, and 6 months using the BAASIS© self-report tool. Patients were classified as adherent if no doses were missed in the prior 4 weeks. Transplant program directors and nurses completed questionnaires regarding care organization and processes. RESULTS: Of the 270 participants, 99 were followed in pediatric programs and 171 in adult programs. Median age was 20.3 years, and median time since transplant was 5 years. At baseline, 71.5% were adherent. Multivariable mixed effects logistic regression models with program as a random effect identified two program-level factors as independently associated with better adherence: minimum number of prescribed blood draws per year for those >3 years post-transplant (per 1 additional) (OR 1.12 [95% CI 1.00, 1.26]; p = .047), and average time nurses spend with patients in clinic (per 5 additional minutes) (OR 1.15 [1.03, 1.29]; p = .017). CONCLUSION: Program-level factors including protocols with a greater frequency of routine blood testing and more nurse time with patients were associated with better medication adherence. This suggests that interventions at the program level may support better adherence.

A measurement framework for adherence in patient decision aid trials applied in a systematic review subanalysis.

OBJECTIVE: To explore how studies of decision aids conceptualize and measure adherence and to evaluate the effect of patient decision aids on adherence. STUDY DESIGN AND SETTING: A subanalysis of adherence studies included in the 2014 Cochrane review on patient decision aids. An adherence framework for decision aid trials is presented which includes two types of adherence: "adherence to choice" and "adherence to treatment." Included studies were classified based on the adherence framework, and their impact on adherence was assessed. RESULTS: Thirteen trials involving 2,115 patients were included. Of these 13, eight measured "adherence to choice" and 10 measured "adherence to treatment." There was considerable heterogeneity in how adherence was measured, with studies varying in whether they considered baseline choice, follow-up choice, or neither, and whether they presented separate or aggregated adherence measures. No studies measuring "adherence to choice" reported significant differences between the decision aid and comparator, whereas four studies measuring adherence to treatment reported a statistically significant difference between the decision aid and comparator, with three favoring the decision aid arm. CONCLUSIONS: The adherence framework provided insight into important measurement factors. There remains considerable heterogeneity in measures of adherence which makes it difficult to draw conclusions.

Pneumocystis pneumonia outbreak among renal transplant recipients at a North American transplant center: Risk factors and implications for infection control.

BACKGROUND: Pneumocystis pneumonia is a severe opportunistic fungal infection. Outbreaks among renal transplant recipients have been reported in Europe and Japan, but never in North America. METHODS: We conducted a retrospective case-control study among adult renal transplant recipients at a Canadian center, using a 3:1 matching scheme. Ten cases and 30 controls were matched based on initial transplantation date, and all patients received prophylaxis with trimethoprim-sulfamethoxazole for 1 year posttransplantation. RESULTS: The median time between transplantation and infection was 10.2 years, and all patients survived. Compared with controls, case patients had statistically lower estimated glomerular filtration rate (29.3 mL/min vs 66.3 mL/min; P = .028) and lymphopenia (0.51 × 10(9)/L vs 1.25 × 10(9)/L; P = .002). Transmission mapping revealed significant overlap in the clinic and laboratory visits among case vs control patients (P = .0002). One hundred percent of patients (4 out of 4) successfully genotyped had the same strain of Pneumocystis jirovecii. CONCLUSIONS: Our study demonstrated an outbreak of pneumocystis more than 10 years following initial transplantation, despite using recommended initial prophylaxis. We identified low estimated glomerular filtration rate and lymphopenia as risk factors for infection. Overlapping ambulatory care visits were identified as important potential sources of infection transmission, suggesting that institutions should re-evaluate policy and infrastructure strategies to interrupt transmission of respiratory pathogens.

Factors Associated with Unplanned Dialysis Starts in Patients followed by Nephrologists: A Retropective Cohort Study.

The number of patients starting dialysis is increasing world wide. Unplanned dialysis starts (patients urgently starting dialysis in hospital) is associated with increased costs and high morbidity and mortality. Risk factors for starting dialysis urgently in hospital have not been well studied. The primary objective of this study was to identify risk factors for unplanned dialysis starts in patients followed in a multidisciplinary chronic kidney disease (CKD) clinic. We performed a retrospective cohort study of 649 advanced CKD patients followed in a multidisciplinary CKD clinic at a tertiary care hospital from January 01, 2010 to April 30, 2013. Patients were classified as unplanned start (in hospital) or elective start. Multivariable logistic regression was used to identify variables associated with unplanned dialysis initiation. 184 patients (28.4%) initiated dialysis, of which 76 patients (41.3%) initiated dialysis in an unplanned fashion and 108 (58.7%) starting electively. Unplanned start patients were more likely to have diabetes (68.4% versus 51.9%; p = 0.04), CAD (42.1% versus 24.1%; p = 0.02), congestive heart failure (36.8% versus 17.6%; p = 0.01), and were less likely to receive modality education (64.5% vs 89.8%; p < 0.01) or be assessed by a surgeon for access creation (40.8% vesrus 78.7% p < 0.01). On multivariable analysis, higher body mass index (OR 1.07, 95% CI 1.02, 1.13), and a history of congestive heart failure (OR 2.41, 95% CI 1.09, 5.41) were independently associated with an unplanned start. Unplanned dialysis initiation is common among advanced CKD patients, even if they are followed in a multidisciplinary chronic kidney disease clinic. Timely education and access creation in patients at risk may lead to lower costs and less morbidity and mortality.

Whose choice is it? Shared decision making in nephrology care.

Patients living with end-stage renal disease (ESRD) are faced with numerous decisions across the trajectory of their illness. Shared decision making (SDM) offers a patient-centered approach to engage patients in decision making in meaningful ways. Using an SDM approach, patients and providers collaborate to make healthcare decisions by taking into account the best available empirical evidence, in conjunction with the patient's values, preferences, and individual circumstances. In this article, we outline the principles of SDM; highlight the broad range and context of decisions faced by patients living with ESRD; review decision-support interventions; and consider opportunities and challenges for implementing SDM into usual ESRD practice. A summary of current knowledge and areas for research and further investigation concludes the paper. Because nephrology team members spend a lot of time interacting with patients during treatments and follow-up care, they are well positioned to engage in SDM. Healthcare systems need innovation in communication to ensure the ethical application of important technological improvements in renal treatments, and to ensure that patient decision-support processes are available. SDM is a promising innovation to support the recalibration of care for patients living with end-stage renal disease.

Adherence: a concept analysis.

AIM: This paper is a report of an analysis of the concept of adherence. BACKGROUND: The transition in terminology from compliance to adherence, and more recently to concordance, requires re-clarification of 'adherence' as a concept in nursing practice. Differences exist in the use of the term adherence and how or if it differs from compliance or concordance. DATA SOURCES: Using the Medical Subject Headings terms adherence, non-adherence and treatment refusal, the Cumulative Index to Nursing and Allied Health Literature, Medline, PsychINFO and Cochrane library databases were searched for publications between 1970 and 2007. Method. The evolutionary analytic method was used to identify and explore transitions in the concept of adherence over time and across healthcare disciplines. A representative sample of papers was identified from the disciplines of nursing, medicine, psychology and pharmacy. RESULTS: We identified 114 papers: 27 from nursing, 39 from psychology, 33 from general medicine and 15 from pharmacology sources. The final sample included eight from pharmacy and 15 from mental health, medicine and nursing. We found no distinct differentiation between adherence and compliance. The surrogate terms serving as manifestations of adherence are concordance, agreement, cooperation and partnership. The most common definition found was as follows: 'Adherence can be defined as the extent to which patients follow the instructions they are given for prescribed treatments'. No definition of adherence exists that reflects a patient-centred approach, the dynamic nature of adherence behaviour and the power imbalance implied by these terms. CONCLUSION: This concept analysis of adherence is a preliminary step towards broadening nurses' appreciation of the complexity of patient adherence behaviour.

Methodological issues encountered in a study of hospitalized COPD patients.

A study with hospitalized chronic obstructive pulmonary disease (COPD) patients determined the feasibility of providing and evaluating a tailored education program. This article describes two methodological issues encountered. Issues included recruitment and retention, and selection of outcome measures. The COPD Self-Efficacy Scale (CSES) and Dartmouth Functional Health Status (FHS) charts provided data on evaluation and outcome measurements. Of 67 patients, 55% met eligibility criteria, 73% (n = 27) agreed to participate, and 74% (n = 20) completed the study. Results revealed acceptance and satisfaction with the educational intervention. The median CSES score, significantly (z = 3.51,p = .004) improved from 53% to 82%. In FHS, a 20% improvement occurred in all except social support. Methodological concerns with the CSES reinforced the need for further investigation of the reliability and validity for hospitalized COPD patients. Researchers' observations may assist in planning educational interventions and program evaluations with hospitalized COPD patients.
