RESUMO

BACKGROUND: Particularly in the context of severe diseases like cancer, many patients wish to include caregivers in the planning of treatment and care. Many caregivers like to be involved but feel insufficiently enabled. This study aimed at providing insight into patients' and caregivers' perspectives on caregivers' roles in managing the patient portal of an electronic personal health record (PHR). METHODS: A descriptive qualitative study was conducted comprising two study phases: (1) Usability tests and interviews with patients with cancer and caregivers (2) additional patient interviews after a 3-month-pilot-testing of the PHR. For both study parts, a convenience sample was selected, focusing on current state of health and therapy process and basic willingness to participate and ending up with a mixed sample as well as saturation of data. All interviews were audio-recorded, pseudonymized, transcribed verbatim and qualitatively analyzed. RESULTS: Two main categories emerged from qualitative data: 'Caregivers' role' and 'Graduation of access rights' - consisting of four subcategories each. The interviewed patients (n = 22) and caregivers (n = 9) felt that the involvement of caregivers is central to foster the acceptance of a PHR for cancer patients. However, their role varied from providing technical support to representing patients, e.g. if the patient's state of health made this necessary. Heterogeneous opinions emerged regarding the question whether caregivers should receive full or graduated access on a patient's PHR. CONCLUSIONS: In order to support the patient and to participate in the care process, caregivers need up-to-date information on the patient's health and treatment. Nevertheless, some patients do not want to share all medical data with caregivers, which might strain the patient-caregiver relationship. This needs to be considered in development and implementation of personal health records. Generally, in the debate on patient portals of a personal health record, paying attention to the role of caregivers is essential. By appreciating the important relationship between patients and caregivers right from the beginning, implementation, of a PHR would be enhanced. TRIAL REGISTRATION: ISRCTN85224823 . Date of registration: 23/12/2015 (retrospectively registered).

RESUMO

BACKGROUND/OBJECTIVES: Solid pseudopapillary neoplasms of the pancreas (SPN) are rare tumors. For patients with unresectable liver metastases of SPN, no standard treatment has been defined so far. Here we report a case of a 40-year-old woman with SPN and metastases confirmed to the liver, and disease progression in the liver after primary tumor resection and chemotherapy with gemcitabine and cisplatin. METHODS: Chemosaturation with percutaneous hepatic perfusions is a minimally invasive, repeatable regional therapy which delivers chemotherapy directly to the liver while limiting systemic toxicity. As an individual treatment approach, the patient was treated with chemosaturation with percutaneous hepatic perfusions of melphalan. RESULTS: The procedure was performed twice within 8 weeks after which the liver metastases showed a marked reduction in size and vascularization (partial response). Grade 3 leukopenia after the second procedure was managed effectively with granulocyte colony-stimulating factor. No other toxicities were observed. Ten months after initiating treatment, the patient had a good performance status and remained stable. CONCLUSIONS: For SPN with unresectable liver metastases and progression despite systemic treatment, repeat chemosaturation with high-dose melphalan may also offer an effective regional treatment option.

RESUMO

Cadmium (Cd(2+)) is a widespread environmental pollutant, which is associated with a wide variety of cytotoxic and metabolic effects. Recent studies showed that intoxication with the heavy metal most importantly targets the integrity of the epithelial barrier. In our study, the lung epithelial cell line, NCI H441, was cultured with the endothelial cell line, ISO-HAS-1, as a bilayer on a 24-well HTS-Transwell filter plate. This coculture model was exposed to various concentrations of CdCl(2). The transepithelial electrical resistance decreased on the apical side only after treatment with high Cd(2+) concentrations after 48 h. By contrast, a breakdown of TER to less than 5% of baseline could be observed much earlier (after 24 h) when Cd(2+) was administered from the basal side. Observations of cell layer fragmentation and widening of intercellular spaces confirmed the barrier breakdown only for the basolaterally treated samples. Furthermore, the cytotoxicity and release of proinflammatory markers was enhanced if samples were exposed to Cd(2+) from the basal side compared to treatment from the apical side. Moreover, we could demonstrate that a high concentration of Ca(2+) could prevent the barrier-disrupting effect of Cd(2+). In conclusion, the exposure of Cd(2+) to cocultures of lung cells caused a decrease in TER, major morphological changes, a reduction of cell viability and an increase of cytokine release, but the effects markedly differed between the two modes of exposure. Therefore, our results suggest that intact epithelial TJs may play a major role in protecting the air-blood barrier from inhaled Cd(2+).

RESUMO

BACKGROUND: Mobile phone video call applications generally did not undergo testing in randomised controlled clinical trials prior to their implementation in patient care regarding the rate of successful patient visits and impact on the physician-patient relationship. METHODS: The National Center for Tumour Diseases (NCT) MOBILE trial was a monocentric open-label randomised controlled clinical trial of patients with solid tumours undergoing systemic cancer therapy with need of a follow-up visit with their consulting physician at outpatient clinics. 66 patients were 1:1 randomised to receive either a standard in-person follow-up visit at outpatient clinics or a video call via a mobile phone application. The primary outcome was feasibility defined as the proportion of patients successfully completing the first follow-up visit. Secondary outcomes included success rate of further video calls, time spent by patient and physician, patient satisfaction and quality of physician-patient relationship. FINDINGS: Success rate of the first follow-up visit in the intention-to-treat cohort was 87.9% (29 of 33) for in-person visits and 78.8% (26 of 33) for video calls (relative risk: RR 0.90, 95% CI 0.70 to 1.13, p=0.51). The most common reasons for failure were software incompatibility in the video call and no-show in the in-person visit arm. The success rate for further video visits was 91.7% (11 of 12). Standardised patient questionnaires showed significantly decreased total time spent and less direct costs for patients (Δmean -170.8 min, 95% CI -246 min to -95.5 min), p<0.0001; Δmean -€14.37, 95% CI -€23.9 to -€4.8, p<0.005) and comparable time spent for physicians in the video call arm (Δmean 0.5 min, 95% CI -5.4 min to 6.4 min, p=0.86). Physician-patient relationship quality mean scores assessed by a validated standardised questionnaire were higher in the video call arm (1.13-fold, p=0.02). INTERPRETATION: Follow-up visits with the tested mobile phone video call application were feasible but software compatibility should be critically evaluated. TRIAL REGISTRATION NUMBER: DRKS00015788.

RESUMO

BACKGROUND: Personal electronic health records (PHR) are considered instrumental in improving health care quality and efficiency, enhancing communication between all parties involved and strengthening the patient's role. Technical architectures, data privacy, and applicability issues have been discussed for many years. Nevertheless, nationwide implementation of a PHR is still pending in Germany despite legal regulations provided by the eHealth Act passed in 2015. Within the information technology for patient-oriented care project funded by the Federal Ministry of Education and Research (2012-2017), a Web-based personal electronic health record prototype (PEPA) was developed enabling patient-controlled information exchange across different care settings. Gastrointestinal cancer patients and general practitioners utilized PEPA during a 3-month trial period. Both patients and physicians authorized by them could view PEPA content online and upload or download files. OBJECTIVE: This paper aims to outline findings of the posttrial qualitative study carried out to evaluate user-reported experiences, perceptions, and perspectives, focusing on their interpretation of PEPA beyond technical usability and views on a future nationwide implementation. METHODS: Data were collected through semistructured guide-based interviews with 11 patients and 3 physicians (N=14). Participants were asked to share experiences, views of perceived implications, and perspectives towards nationwide implementation. Further data were generated through free-text fields in a subsequent study-specific patient questionnaire and researcher's notes. Data were pseudonymized, audiotaped, and transcribed verbatim. Content analysis was performed through the Framework Analysis approach. All qualitative data were systemized by using MAXQDA Analytics PRO 12 (Rel.12.3.1). Additionally, participant characteristics were analyzed descriptively using IBM SPSS Statistics Version 24. RESULTS: Users interpreted PEPA as a central medium containing digital chronological health-related documentation that simplifies information sharing across care settings. While patients consider the implementation of PEPA in Germany in the near future, physicians are more hesitant. Both groups believe in PEPA's concept, but share awareness of concerns about data privacy and older or impaired people's abilities to manage online records. Patients perceive benefits for involvement in treatment processes and continuity of care but worry about financing and the implementation of functionally reduced versions. Physicians consider integration into primary systems critical for interoperability but anticipate technical challenges, as well as resistance from older patients and colleagues. They omit clear positioning regarding PEPA's potential incremental value for health care organizations or the provider-patient relationship. CONCLUSIONS: Digitalization in German health care will continue to bring change, both organizational and in the physician-patient relationship. Patients endorse and expect a nationwide PEPA implementation, anticipating various benefits. Decision makers and providers need to contribute to closing modernization gaps by committing to new concepts and by invigorating transformed roles.

RESUMO

BACKGROUND: A significant potential for patient empowerment is seen in concepts aiming to give patients access to their personal health information (PHI) and to share this PHI across different care settings and health systems. Personal health records (PHRs) and the availability of information through health information exchanges are considered to be key components of effective and efficient health care. With tethered PHRs, as often used in the United States, patients' opportunities to manage their PHI are strongly restricted. Therefore, within the INFOPAT (information technology for patient oriented care) project (2012-2016) in Germany, funded by the Federal Ministry of Education and Research (BMBF), the development of a patient-controlled "personal electronic health record" (PEPA) was based on user requirements right from the beginning. OBJECTIVE: The overall objective of the study is to implement and evaluate a PEPA prototype for patients with colorectal cancer who are treated at the National Center for Tumor Diseases in Heidelberg. To achieve this aim, this study has 2 parts: a pre-implementation study (phase 1) and an implementation study (phase 2). The pre-implementation study will include a usability evaluation of the PEPA approach and the consideration of organizational preconditions for the implementation. With the implementation study, we will evaluate the process of implementation (eg, barriers or facilitators), the need for organizational change (eg, processes of communication), and the impact on outcomes (eg, self-efficacy, involvement in care). METHODS: The pre-implementation study is based on a mixed methods approach and comprises qualitative and quantitative element according to our research aim. We will use a think-aloud method for the usability analysis. Additionally, participants will be asked to evaluate their overall satisfaction based on a standardized questionnaire, the System Usability Scale. For the analysis of preconditions, we will conduct semistructured personal interviews with, for example, patients, medical assistants, and physicians. Within the implementation study the outcome evaluation is planned as a prospective, 3-month, open-label "before and after" trial. Additionally, for the analysis of processes and the need for organizational change, we will conduct interviews with the participants (eg, patients, general practitioners, physicians) of the before and after trial. RESULTS: This project is part of the INFOPAT project, which is funded (2012-2016) by the Federal Ministry of Education and Research (BMBF). The enrolment was completed in July 2016. Data analysis is currently under way and the first results are expected to be submitted for publication at end of 2017. CONCLUSIONS: Existing approaches of PHRs aim to give patients access to their treatment data. With the PEPA approach and this study, we go a step further: patients have access to their PHI and they can give other persons (eg, their general practitioner) access. With this approach, new possibilities for professional collaboration and the engagement of patients can arise.

RESUMO

Sulphur and nitrogen mustard are strong alkylating agents which can cause after inhalation acute lung injury in the larynx, trachea and large bronchi and can lead to alveolar edema. In our study we tested the N-Lost l-Phenylalanine Mustard (l-Pam). Therefore we seeded the alveolar type II cell line NCI H441 on the upper membrane of a Transwell filter plate and the endothelial cell line ISO-Has-1 on the lower side of the membrane for the alveolar model and combined the human bronchial explant-outgrowth cells and fibroblasts in the bronchial model and exposed both models with various concentrations of l-Pam. Treatment with l-Pam led to a concentration-dependent decrease of the transepithelial electrical resistance and therefore impairment of barrier function in both models. Changes in morphology could be observed. In the bronchial model damaged cell organelles whereas in the alveolar model a widening of intercellular spaces could be seen. Loss of cell-matrix adhesion as well as apoptotic and necrotic cell death could be demonstrated. In conclusion, treatment with the nitrogen mustard in the coculture models showed comparable results to sulphur mustard treatment and thus this model could be useful to explore similarities and differences in signal transduction pathways after treatment with both sulphur and nitrogen mustard.
