Prevalence and correlates of medication non-adherence among kidney transplant recipients more than 6 months post-transplant: a cross-sectional study.

ABSTRACT: Among kidney transplant recipients, non-adherence with immunosuppressive medications frequently precedes allograft loss. We sought to determine the prevalence and correlates of medication non-adherence among kidney transplant recipients.We performed a single-center, cross-sectional study of kidney transplant recipients who were at least 6 months post-transplant. We measured self-reported adherence using the Immunosuppressive Therapy Adherence Scale (ITAS, which is scored from 0 to 12, where higher scores indicate increased adherence) and barriers to adherence using the Immunosuppressive Therapy Barriers Scale (ITBS). We also used validated scales to measure perceived stress, health literacy, anxiety, depression, and interpersonal support.The 252 patients included in the study were 59.9% male, 27.0% Black, and at a median of 2.9 years post-transplant (interquartile range [IQR] 1.4-5.8). On the ITAS, 59.1% scored a perfect 12, 26.6% scored 10-11, and 14.3% scored 0-9. In univariate models, non-adherence (defined as ITAS score ?9) was significantly associated with increased scores on scales for perceived stress (OR 1.12, 95% CI 1.01-1.25) and depression (OR 1.14, 95% CI 1.02-1.28), and with more self-reported barriers to adherence on the ITBS (OR 1.15, 95% CI 1.08-1.22). After adjusting for sociodemographic factors, stress and depression were not associated with non-adherence. Higher scores on the ITBS (corresponding to more self-described barriers to adherence) were associated with lower scores on the ITAS (P < 0.001). Several individual barriers were associated with non-adherence.Among prevalent kidney transplant recipients, a minority is non-adherent. Practical barriers to adherence may serve as promising targets for future interventions.

Project description:BACKGROUND:During routine post-kidney transplant care, most European transplant physicians screen patients for asymptomatic bacteriuria. The usefulness of this strategy is debated. To make screening cost-effective, asymptomatic bacteriuria should be prevalent enough to justify the expense, and antibiotics should improve patient outcomes significantly if asymptomatic bacteriuria is detected. Regrettably, the prevalence of asymptomatic bacteriuria among kidney transplant recipients is not well defined. METHODS:To determine the prevalence of asymptomatic bacteriuria among kidney transplant recipients, we did a cross-sectional study among kidney transplant recipients undergoing routine surveillance in three outpatient transplant clinics in Belgium and France. We excluded patients who were in the first two months post-transplantation and/or had a urinary catheter. Asymptomatic participants who had a urine culture with one organism isolated at ? 105 CFU/mL were asked to provide a confirmatory urine specimen. Asymptomatic bacteriuria was defined per Infectious Diseases Society of America guidelines. RESULTS:We screened 500 consecutive kidney transplant recipients. Overall, the prevalence of asymptomatic bacteriuria was 3.4% (17/500 patients). It was similarly low among kidney transplant recipients who were between 2 and 12 months after transplantation (1.3%, 1/76 patients) and those who were farther after transplantation (3.8%, 16/424 patients: p = 0.49). Asymptomatic bacteriuria was significantly associated with female gender (risk ratio 3.7, 95% CI 1.3-10.3, p = 0.007) and older age (mean age: 61 ± 12 years [bacteriuric participants], versus 53 ± 15 years [non-bacteriuric participants], p = 0.03). One participant's colistin-resistant Escherichia coli isolate carried the globally disseminated mcr-1 gene. CONCLUSIONS:Among kidney transplant recipients who are beyond the second month post-transplant, the prevalence of asymptomatic bacteriuria is low. Further studies are needed to ascertain the cost-effectiveness of a screen-and-treat strategy for asymptomatic bacteriuria in this population.

Project description:Aims and objectivesTo explore the prevalence of psychological distress such as anxiety, depression and post-traumatic stress disorder and its associations with medication adherence in lung transplant patients.BackgroundPsychological distress after lung transplantation may impact clinical outcomes by associated behaviours such as non-adherence to medication. Evidence about the relation between psychological distress and medication adherence in lung transplant patients is limited and not well explained.Design and methodsWe conducted a single-centre study with a cross-sectional design in 73 lung transplant candidates and 116 recipients. Questionnaires were the Brief Symptom Inventory, Impact of Event Scale and Basel Assessment of Adherence to Immunosuppressive Medications Scale. The STROBE checklist was monitored.ResultsIn candidates, 39.7% reported (sub)clinical symptoms of depression, in recipients this was 21.6%. We observed suicidal ideation in recipients (8.6%), and candidates (5.5%). The prevalence of (sub)clinical symptoms of anxiety was 38.3% in candidates and 33.7% in recipients. After lung transplantation, 12% of the recipients reported clinical symptoms of PTSD related to the transplantation. Symptoms of anxiety and medication adherence were significantly and positively related in transplant recipients. We found no association between depressive or post-traumatic stress symptoms, and medication adherence.ConclusionsIn lung transplant patients, we found a high prevalence of symptoms of depression and anxiety. Recipients had high levels of post-traumatic stress symptoms related to the transplantation. The prevalence of suicidal ideation was unexpectedly high in recipients. After lung transplantation, higher levels of anxiety were related to better medication adherence. We propose that LTX recipients are very anxious to develop dyspnoea and therefore take their medication more conscientiously.Relevance to clinical practiceThe clinical nurse specialist can play a key role in identifying and addressing psychological and behavioural problems. More prospective research on the role of anxiety and dyspnoea in lung transplant recipients is recommended.

Project description:IntroductionPatients receiving a haematopoietic stem cell transplant (HSCT) are subjected to complex oral medications based on prophylactic and immunosuppressive treatments. Adherence to medication plays a role in survival, and medication non-adherence (MNA) is closely associated with graft-versus-host disease and other complications. The aim of this systematic review is to summarise the available evidence regarding prevalence rates of medication adherence, the risk factors of MNA, the effectiveness of interventions to increase medication adherence and the outcomes associated with MNA.Methods and analysisWe designed a systematic review according to the Joanna Briggs Institute methodology. We will search the Cochrane Library and the CINAHL, EMBASE, MEDLINE via PubMed, PsycINFO and Scopus databases. We will include published and unpublished primary studies: (a) on humans, from inception until 10 May 2022; (b) written in any language; (c) experimental (randomised and non-randomised), observational (prospective, retrospective cohort and case-control), correlational, cross-sectional and longitudinal; and (d) with a low risk of bias, according to the quality assessment we perform. We will exclude secondary and qualitative studies, protocols, publications without original data, including paediatrics or related to autologous HSCT. The primary outcome will be the prevalence of oral medication adherence; the secondary outcomes will be the risk factors of MNA, the interventions aimed at increasing medication adherence and the outcomes of MNA. Two researchers will independently screen the eligible studies, then extract and describe the data. Disagreements will be resolved by a third researcher. We will provide a qualitative narrative synthesis of the findings.Ethics and disseminationEthical approval is not required given that previously published studies will be used. We will disseminate the findings through conference presentations and publications in international peer-reviewed scientific journals.Prospero registration numberCRD42022315298.
