Cystic fibrosis (CF) care through the patients' eyes – A nationwide survey on experience and satisfaction with services using a disease-specific questionnaire

SummaryThe patients' perspective is an important aspect of quality management. A newly developed disease-specific questionnaire was used to assess the patients' experiences with care provided in specialised cystic fibrosis (CF) care centres.Methods90 CF centres in Germany were invited to participate. Centre staff collected patient consent forms and sent the patients' addresses to the study centre. The questionnaires for adults and parents had 100 and 104 items respectively, with 3–6 response categories each. Items were dichotomised into “problem scores” (PS), indicating the presence or absence (PS 0%) of a reported problem.Results56 CF centres took part in the survey and recruited 1642 adults with CF and 1205 parents. The response rates were 74% in each group, with 1221 completed questionnaires from adults and 891 from parents. Participants reported good experiences with care. Factor analysis revealed 10 factors covering 70 items. Participants reported the best results for the factors “Physiotherapists” (PS 6%) and “Physician–Patient Relationship” (PS 9%). Factors with the highest problem scores were inpatient and outpatient “Facilities, Hygiene and Services”. CF centres received reports of their own results and mean problem scores of all participating institutions. The problem scores differed considerably between CF centres.ConclusionsThe nation-wide CF-specific patient experience survey identified specific shortcomings which were mainly related to communication, centre organisation, and facilities. Centre staff can use the results to improve the quality of care. We suggest that patients' views should become an integral component of efforts to promote patient-centred care

In Vivo Killing Capacity of Cytotoxic T Cells Is Limited and Involves Dynamic Interactions and T Cell Cooperativity.

According to in vitro assays, T cells are thought to kill rapidly and efficiently, but the efficacy and dynamics of cytotoxic T lymphocyte (CTL)-mediated killing of virus-infected cells in vivo remains elusive. We used two-photon microscopy to quantify CTL-mediated killing in mice infected with herpesviruses or poxviruses. On average, one CTL killed 2-16 virus-infected cells per day as determined by real-time imaging and by mathematical modeling. In contrast, upon virus-induced MHC class I downmodulation, CTLs failed to destroy their targets. During killing, CTLs remained migratory and formed motile kinapses rather than static synapses with targets. Viruses encoding the calcium sensor GCaMP6s revealed strong heterogeneity in individual CTL functional capacity. Furthermore, the probability of death of infected cells increased for those contacted by more than two CTLs, indicative of CTL cooperation. Thus, direct visualization of CTLs during killing of virus-infected cells reveals crucial parameters of CD8(+) T cell immunity
