High Prevalence of Posttraumatic Stress Disorder Symptoms Found in Well-Treated People with HIV after the Introduction of Patient-Reported Outcome Measures
People with HIV (PWH) are at greater risk of experiencing mental health problems, such as depression and post-traumatic stress disorder (PTSD). The purpose of our study was to determine the prevalence of posttraumatic stress disorder PTSD in PWH. PWH in care Amsterdam University Medical center (Amsterdam UMC) with access to the electronic patient portal were offered patient-reported outcome measures (PROMs) between May 2022 and May 2023, includin…
Intentional- but not Unintentional Medication Non-adherence was Related with Beliefs about Medicines Among a Multi-Ethnic Sample of People with HIV
Medication non-adherence can be intentional or unintentional. We investigated the prevalence of unintentional and intentional non-adherence to antiretroviral therapy (ART) and the relationship with beliefs about medicines, sociodemographic- and HIV-related variables among people with HIV (PWH) attending the HIV clinic of the Amsterdam University Medical Centers. Participants completed the Medication Adherence Rating Scale (MARS) and the Beliefs a…
Response shift after coronary revascularization
Results indicate response shift in HRQoL following coronary revascularization. While we did not find an impact of response shift on the estimates of change, the SEM approach provides a more comprehensive insight into the different types of change in HRQoL following coronary revascularization
Sub-optimal adherence to combination anti-retroviral therapy and its associated factors according to self-report, clinician-recorded and pharmacy-refill assessment methods among HIV-infected adults in…
Adherence to combination antiretroviral therapy (cART) is generally high in most resource-limited settings. However, sub-optimal adherence occurs in a sizable proportion of patients, and is independently predictive of detectable viremia. We investigated sub-optimal adherence according to self-report, clinician-recorded, and pharmacy-refill assessment methods, and their associated factors among HIV-infected adults receiving cART in Addis Ababa, Et…
Narrative meaning making and integration
Falling seriously ill is often experienced as a life event that causes conflict with people’s personal goals and expectations in life and evokes existential questions. This article presents a new humanities approach to the way people make meaning of such events and how this influences their quality of life. Incorporating theories on contingency, narrative identity, and quality of life, we developed a theoretical model entailing the concepts life …
Structure and quality of outpatient care for people living with an HIV infection
Policy-makers and clinicians are faced with a gap of evidence to guide policy on standards for HIV outpatient care. Ongoing debates include which settings of care improve health outcomes, and how many HIV-infected patients a health-care provider should treat to gain and maintain expertise. In this article, we evaluate the studies that link health-care facility and care provider characteristics (i.e., structural factors) to health outcomes in HIV-…
Health-related quality of life of HIV-infected adults receiving combination antiretroviral therapy in Addis Ababa
Health-related quality of life (HRQoL) is an important outcome measure among HIV-infected patients receiving combination antiretroviral therapy (cART), but has not been studied extensively in resource-limited settings. Insight in the predictors or correlates of poor HRQoL may be helpful to identify patients most in need of additional support and to design appropriate interventions. A cross-sectional study was conducted between September 2012 and …
Feasibility of Real Time Medication Monitoring Among HIV Infected and TB Patients in a Resource-Limited Setting
Predictors and correlates of adherence to combination antiretroviral therapy (ART) for chronic HIV infection
HIV Stigma and Depressive Symptoms are Related to Adherence and Virological Response to Antiretroviral Treatment Among Immigrant and Indigenous HIV Infected Patients
We compared adherence to cART and virological response between indigenous and immigrant HIV-infected patients in the Netherlands, and investigated if a possible difference was related to a difference in the psychosocial variables: HIV-stigma, quality-of-life, depression and beliefs about medications. Psychosocial variables were assessed using validated questionnaires administered during a face-to-face interview. Adherence was assessed trough phar…
Which method of adherence measurement is most suitable for daily use to predict virological failure among immigrant and non-immigrant HIV-1 infected patients
In industrialized countries, virological failure occurs more often among HIV-infected immigrant patients. Non-adherence is the most credible explanation. We compared adherence of immigrant patients with that of non-immigrant patients in the Netherlands, and investigated which method of adherence measurement is most suitable for daily use to predict virological treatment failure: testing knowledge of the current regimen, a quantitative adherence i…
An assessment of factorial structure and health-related quality of life in problem drug users using the Short Form 36 Health Survey
Are Retrospective Measures of Change in Quality of Life More Valid Than Prospective Measures
BACKGROUND: Adaptation to changing health presents a challenge to measuring change in quality of life (QoL). Previous studies have shown that different methods for measuring change yield different results, but it is unclear which method provides a more valid measurement of change. We investigated which of 3 commonly used methods for measuring change in QoL yielded the strongest associations with clinical measures of change in health status. METHO…
