Maturity and adherence in adolescent and young adult heart recipients.

BACKGROUND: Pediatric transplant (txp) teams note high rates of non-adherence and risky behaviors linked to morbidity and mortality among adolescent and young adult recipients. Clinicians and parents alike report symptoms of social immaturity and failure to appreciate consequences of risky behavior; relationships between the two have not been studied in this population. METHOD: This two-phase mixed method study examined adherence, high-risk behaviors, and maturity in a sample of 27 heart recipients, aged 15-31, who underwent transplantation in childhood or adolescence at Children's Hospital of Pittsburgh. All subjects completed a projective ego development measure and a questionnaire about adherence to the post-txp regimen. Nine recipients, purposely selected for good or poor adherence according to criteria determined by the transplant team and matched on age, participated in phase 2 qualitative interviews and mood assessments. RESULTS: Sixty-three percent of the phase 1 sample missed medications, 67% missed appointments, 11% smoked, 37% had difficulty with diet, 89% exercised infrequently, 33% had tattoos, 26% had more than two body piercings, and 11% used street drugs. Six themes and a core construct of maturity were identified with qualitative methodology. Poor adherers were less mature on every theme and consistently scored at a less mature level on the projective measure of ego development. Chronological age was not related to the level of maturity in qualitative or projective data. Most interview subjects reported high levels of anxiety, and two reported clinically significant levels of depression and anger; mood was not related to adherence. CONCLUSIONS: Non-adherence and high-risk behaviors are prevalent among adolescent and young adult heart recipients. Level of maturity appears to be associated with ability to adhere to the treatment regimen and avoid high-risk behaviors.

Psychological and cognitive function: predictors of adherence with cholesterol lowering treatment.

BACKGROUND: Failure to adhere to medication regimes is a significant problem in clinical and research settings yet reliable, consistent identification of key psychosocial predictors remains elusive. Studies of mood and personality related to adherence show mixed results-compliance and objectively measured cognitive function are intuitively related but empirical support is lacking. PURPOSE: This study is a secondary analysis to examine the relations between adherence with a medication regime for lowering serum cholesterol and several domains of psychological and cognitive functioning. METHODS: Participants in the initial study completed a measure of personality and a battery of neuropsychological measures at baseline; anxiety and depression were measured at baseline and at 4-week intervals. Medication adherence was tracked with electronic cap monitors for 24 weeks. RESULTS: Only 23% of the sample was fully adherent to medication regimes at least 80% of the time over the 6-month study period. Conscientiousness, according to the Five Factor Theory of Personality, and estimated IQ remained robust predictors of adherence in hierarchical regression analyses. Depression and anxiety, mental flexibility, and visuospatial-constructional ability were less robust but statistically significant (p <.05) correlates of adherence. CONCLUSIONS: Although results of this analysis explain only a portion of the variance in adherence, they demonstrate the importance of trait psychological and cognitive factors in adherence research.

Psychosocial vulnerability, physical symptoms and physical impairment after lung and heart-lung transplantation.

BACKGROUND: Many lung and heart-lung transplant recipients experience distressing physical symptoms and elevated physical impairment levels. Although post-transplant complications and secondary illnesses may largely account for these health limitations, patients' psychosocial well-being may influence them as well. We examined the contribution of psychosocial variables to patients' experience of physical symptoms and physical impairment. METHODS: The study consisted of a cross-sectional sample of 50 patients (36 lung, 14 heart-lung) at between 2 and 17 months post-transplant. They were interviewed to assess physical symptoms, current physical impairment and psychosocial well-being in the areas of mental health, sense of mastery and coping. Medical record reviews established the presence of medical complications and secondary illnesses concurrent with the interviews. Descriptive analyses examined the range of symptoms and levels of physical impairment experienced. Bivariate analyses and multivariate linear regression examined relationships between key variables. RESULTS: Average number of physical symptoms and level of physical impairment met or exceeded levels reported in other transplant samples. Elevated depressive and anxiety symptoms, a low sense of mastery, and the presence of concurrent medical complications were each associated with increased number of physical symptoms and physical impairment level. When the impact of concurrent medical complications was controlled, recipients with elevated psychologic distress remained significantly more likely to report more physical symptoms and higher physical impairment levels. CONCLUSIONS: Patients' physical health status may be influenced by many factors. To the extent that psychologic distress increases the likelihood of perceived physical limitations, timely identification and treatment of distress may help to maximize quality of life after lung and heart-lung transplantation.

Personality characteristics among cardiothoracic transplant recipients.

Personality characteristics are clinically believed to predict posttransplant adherence and outcome; however, data, as to the prevalence and type of personality disorders (PDs) and distribution of personality traits among transplant (txp) populations, are sparse and inconclusive. This paper reports on the prevalence and type of PD and range of personality traits, according to the Five-Factor model, among 73 adult cardiothoracic txp recipients. It represents the first systematic assessment of PDs and traits in a sample of txp recipients. Personality disorders were assessed with a semistructured diagnostic interview; personality traits were assessed with a self-report instrument. Thirty-three percent of the sample met diagnostic criteria for a PD, approximately three times higher than prevalence of PD previously reported among nonpsychiatric populations. Mean values of personality traits for the sample were in the normative range but with wide variability; extreme values on four of the five traits were scored by subjects with a PD. This unexpectedly high prevalence of PD and the wide variability in traits among heart and lung recipients alert clinicians to consider personality characteristics when planning interventions to increase compliance and maximize quality of life after cardiothoracic transplantation.

Cognitive function in adult cardiothoracic transplant candidates and recipients.

Innovative surgical and medical techniques have prolonged the life span of cardiothoracic (CT) transplant recipients and made transplantation an option for many older patients. Cognitive function is a key determinant of the CT transplant recipient's ability to manage the complex treatment regimen and experience optimum benefit of the procedure. As the CT population ages, risk of cognitive dysfunction due to normal aging is compounded by the physical and mental changes associated with end-stage organ disease, comorbid conditions, and transplant-related complications. Cognitive abilities consist of (a) receptive functions (ability to select, acquire, classify, and integrate information); (b) memory and learning (ability to store and retrieve information); (c) thinking (ability to mentally organize and reorganize information; and (d) expressive functions (ability to communicate or act upon information). Although each of these functions represents a distinct type of behavior, they are interdependent. The purpose of this article is to (a) discuss the literature regarding cognitive function before and after adult heart, lung, and heart-lung transplantation; (b) identify methodological problems associated with the studies done to date; and (c) make recommendations for future research in this area.
