Project description:Bronchoscopic lung volume reduction (BLVR) offers alternative novel treatments for patients with emphysema. Comprehensive evidence for comparing different BLVR remains unclear. To estimate the effects of different BLVR on patients with emphysema. PubMed, EMBASE, Cochrane Library, and Web of Science databases from January 2001 to August 2017 were searched. Randomized clinical trials evaluated effects of BLVR on patients with emphysema. The relevant information was extracted from the published reports with a predefined data extraction sheet, and the risk of bias was assessed with the Cochrane risk of bias tools. Pair-wise metaanalyses were made using the random-effects model. A random-effects network meta-analysis was applied within a Bayesian framework. The quality of evidence contributing to primary outcomes was assessed using the GRADE framework. 13 trials were deemed eligible, including 1993 participants. The quality of evidence was rated as moderate in most comparisons. Medical care (MC)was associated with the lowest adverse events compared with intrabronchial valve (IBV)(-2.5,[-4.70 to -0.29]), endobronchial valve (EBV) (-1.73, [-2.37 to -1.09]), lung volume reduction coils (LVRC) (-0.76, [-1.24 to -0.28]), emphysematous lung sealant (ELS) (-1.53, [-2.66 to -0.39]), and airway bypass(-1.57, [-3.74 to 0.61]). Adverse events in LVRC were lower compared with ELS (-0.77,[-2.00 to 0.47]). Bronchoscopic thermal vapor ablation (BTVA) showed significant improvement in FEV1 compared with MC (0.99, [0.37 to 1.62]), IBV (1.25, [0.25 to 2.25]), and LVRC (0.72, [0.03 to 1.40] ). Six? minute walking distance (6 MWD) in ELS was significantly improved compared with other four BLVR, sham control, and MC (-1.96 to 1.99). Interestingly, MC showed less improvement in FEV1 and 6MWDcompared with EBV (-0.45, [-0.69 to -0.20] and -0.39, [-0.71 to -0.07], respectively). The mortality in MC and EBV was lower compared with LVRC alone (-0.38, [-1.16 to 0.41] and -0.50, [-1.68 to 0.68], respectively). BTVA and EBV led to significant changes in St George's respiratory questionnaire (SGRQ) compared with MC alone (-0.74, [-1.43 to -0.05] and 0.44, [0.11 to 0.78], respectively). BLVR offered a clear advantage for patients with emphysema. EBV had noticeable beneficial effects on the improvement of forced expiratory volume 1, 6MWD and SGRQ, and was associated with lower mortality compared with MC in different strategies of BLVR.

Project description:Lung volume reduction (LVR) techniques improve lung function in selected patients with emphysema, but the impact of LVR procedures on the asynchronous movement of different chest wall compartments, which is a feature of emphysema, is not known.We used optoelectronic plethysmography to assess the effect of surgical and bronchoscopic LVR on chest wall asynchrony. Twenty-six patients were assessed before and 3 months after LVR (surgical [n = 9] or bronchoscopic [n = 7]) or a sham/unsuccessful bronchoscopic treatment (control subjects, n = 10). Chest wall volumes were divided into six compartments (left and right of each of pulmonary ribcage [Vrc,p], abdominal ribcage [Vrc,a], and abdomen [Vab]) and phase shift angles (?) calculated for the asynchrony between Vrc,p and Vrc,a (?RC), and between Vrc,a and Vab (?DIA).Participants had an FEV? of 34.6 ± 18% predicted and a residual volume of 217.8 ± 46.0% predicted with significant chest wall asynchrony during quiet breathing at baseline (?RC, 31.3° ± 38.4°; and ?DIA, -38.7° ± 36.3°). Between-group difference in the change in ?RC and ?DIA during quiet breathing following treatment was 44.3° (95% CI, -78 to -10.6; P = .003) and 34.5° (95% CI, 1.4 to 67.5; P = .007) toward 0° (representing perfect synchrony), respectively, favoring the LVR group. Changes in ?RC and ?DIA were statistically significant on the treated but not the untreated sides.Successful LVR significantly reduces chest wall asynchrony in patients with emphysema.

Project description:The lung volume reduction coil treatment is a minimally invasive bronchoscopic treatment option for emphysema patients who suffer from severe hyperinflation. The treatment is aimed at a large group of patients where lung volume reduction surgery and bronchoscopic lung volume reduction using endobronchial valves are no option, or alternatively, can be offered as a bridge to lung transplantation. The nitinol coil exhibits a shape memory effect and is biologically inert. The lung volume reduction coil procedure is performed in two separate treatment sessions, targeting one lobe per session, with the contralateral lobe being treated 4 to 8 weeks after the first session. In one treatment session, around 10 to 14 coils, thereby treating an entire lobe, are being placed. Selecting optimally treated, symptomatic chronic obstructive pulmonary disease (COPD) patients with emphysema and severe hyperinflation, while avoiding significant airway disease such as asthma, chronic bronchitis and bronchiectasis, is key to achieve treatment success. Three randomized clinical trials investigating lung volume reduction coil treatment have been published until now, reporting the results of 452 treated patients up to 12 months after coil treatment. Lung volume reduction coil treatment results in significant improvement of pulmonary function outcomes and quality of life in patients with severe hyperinflation. The most common complications of lung volume reduction coil treatment are: COPD exacerbations, pneumonia, Coil Associated Opacity and an increased risk of pneumothorax. The purpose of this article is to describe the coil technique and review the available literature regarding effect, safety and future perspectives of lung volume reduction with coils for emphysema patients.

Project description:BackgroundBronchoscopic lung volume reduction (BLVR), using biological agents, is one of the new alternatives to lung volume reduction surgery.ObjectivesTo evaluate efficacy and safety of biological BLVR using low cost agents including autologous blood and fibrin glue.MethodsEnrolled patients were divided into two groups: group A (seven patients) in which autologous blood was used and group B (eight patients) in which fibrin glue was used. The agents were injected through a triple lumen balloon catheter via fiberoptic bronchoscope. Changes in high resolution computerized tomography (HRCT) volumetry, pulmonary function tests, symptoms, and exercise capacity were evaluated at 12 weeks postprocedure as well as for complications.ResultsIn group A, at 12 weeks postprocedure, there was significant improvement in the mean value of HRCT volumetry and residual volume/total lung capacity (% predicted) (P-value: <0.001 and 0.038, respectively). In group B, there was significant improvement in the mean value of HRCT volumetry and (residual volume/total lung capacity % predicted) (P-value: 0.005 and 0.004, respectively). All patients tolerated the procedure with no mortality.ConclusionBLVR using autologous blood and locally prepared fibrin glue is a promising method for therapy of advanced emphysema in term of efficacy, safety as well as cost effectiveness.

Project description:Limited guidance exists for the implementation of lung volume reduction interventions in routine clinical care. We designed a pragmatic study to evaluate a strategy including endoscopic lung volume reduction (ELVR) and lung volume reduction surgery (LVRS) in heterogeneous emphysema. This prospective monocentre cohort study evaluated ELVR versus no-ELVR, followed by a cohort study evaluating LVRS. Primary outcome was the proportion of subjects with a forced expiratory volume in 1 s (FEV1) improvement of ⩾100 mL at 3-month follow-up. Changes in FEV1, residual volume (RV), 6-min walk distance (6MWD) and quality of life (St George's Respiratory Questionnaire (SGRQ)) were evaluated at 6-month follow-up. Hospital stay and treatment-related serious adverse events were monitored. From 106 subjects screened, 38 subjects were enrolled comparing ELVR (n=20) with no-ELVR (n=18). After 6 months' follow-up, eligible patients were referred for LVRS (n=16) with another 6-month follow-up. At 3-month follow-up, 70% of ELVR compared to 11% of no-ELVR (p<0.001) and 69% of LVRS had an FEV1 improvement of ⩾100 mL. Between-group differences (mean±sem) for ELVR versus no-ELVR at 6-month follow-up were FEV1 +0.21±0.05 L; RV -0.95±0.21 L; 6MWD 58±17 m and SGRQ -18±5 points. At 6-month follow-up, within-group differences (mean±sem) for LVRS showed FEV1 +0.27±0.06 L; RV -1.49±0.22 L and 6MWD +75±18 m. Serious adverse events in 81% versus 45% of subjects (p=0.04) and a median hospital stay of 15 versus 5 days (p<0.001) were observed for LVRS versus ELVR, respectively. This pragmatic prospective cohort study supports a clinical approach with ELVR as a less invasive first option and LVRS as powerful alternative in severe heterogeneous emphysema.

Project description:This study elaborates the research design and methodology to investigate the reverse culture shock (RCS) experience of young Thai tourists in the tourism field. Taking the worldview position of relative ontology and interpretivist/constructivist paradigms, this paper employs qualitative design using multiple research methods, namely, essay writing, graph plotting and semi-structured interview. Essay writing and graph plotting are initially used as pre-interview activities as part of the memory recall procedures. This stage is important because it helps curtail memory distortion and enrich insight into the participant's past RCS experience. The semi-structured interview with young Thai tourists is subsequently conducted to elicit individual perceptual and emotional experiences and coping mechanism after they returned home. The three research methods complement one another to draw out rich travellers' experience in the tourism study and can be beneficial to the extended disciplines of social science and psychology. Advantages of this article include: •Practical and feasible processes for a qualitative study in social science and psychology, particularly when recall of memory is involved.•The ability to gain enriched information of experience.•The ability to elicit emotional aspects from the study of experience through graph plotting.

Project description:PurposePeople diagnosed with cancer experience high distress levels throughout diagnosis, treatment, and survivorship. Untreated distress is associated with poor outcomes, including worsened quality of life and higher mortality rates. Distress screening facilitates need-based access to supportive care which can optimize patient outcomes. This qualitative interview study explored outpatients' perceptions of a distress screening process implemented in an Australian cancer center.MethodsAdult, English-speaking cancer outpatients were approached to participate in face-to-face or phone interviews after being screened by a clinic nurse using the distress thermometer (DT). The piloted semi-structured interview guide explored perceptions of the distress screening and management process, overall well-being, psychosocial support networks, and improvement opportunities for distress processes. Thematic analysis was used.ResultsFour key themes were identified in the 19 interviews conducted. Distress screening was found to be generally acceptable to participants and could be conducted by a variety of health professionals at varied time points. However, some participants found "distress" to be an ambiguous term. Despite many participants experiencing clinical distress (i.e., DT ≥ 4), few actioned referrals; some noted a preference to manage and prevent distress through informal support and well-being activities. Participants' diverse coping styles, such as positivity, acceptance, and distancing, also factored into the perceived value of screening and referrals.Conclusion and implicationsScreening models only measuring severity of distress may not be sufficient to direct care referrals, as they do not consider patients' varying coping strategies, external support networks, understanding of distress terminology, and motivations for accessing supportive care services.

Project description:OBJECTIVES:Improving patient experience is widely regarded as a key component of health care quality. However, while a considerable amount of data are collected about patient experience, there are concerns this information is not always used to improve care. This study explored whether and how frontline staff use patient experience data for service improvement. METHODS:We conducted a year-long ethnographic case study evaluation, including 299?hours of observations and 95 interviews, of how frontline staff in six medical wards at different hospital sites in the United Kingdom used patient experience data for improvement. RESULTS:In every site, staff undertook quality improvement projects using a range of data sources. Teams of health care practitioners and ancillary staff engaged collectively in a process of sense-making using formal and informal sources of patient experience data. While survey data were popular, 'soft' intelligence - such as patients' stories, informal comments and observations - also informed staff's improvement plans, without always being recognized as data. Teams with staff from different professional backgrounds and grades tended to make more progress than less diverse teams, being able to draw on a wider net of practical, organizational and social resources, support and skills, which we describe as team-based capital. CONCLUSIONS:Organizational recognition, or rejection, of specific forms of patient experience intelligence as 'data' affects whether staff feel the data are actionable. Teams combining a diverse range of staff generated higher levels of 'team-based capital' for quality improvement than those adopting a single disciplinary approach. This may be a key mechanism for achieving person-centred improvement in health care.

Project description:BackgroundOver recent decades, numerous medical procedures have migrated out of hospitals and into freestanding ambulatory surgery centers (ASCs) and physician offices, with possible implications for patient outcomes. In response, states have passed regulations for office-based surgeries, private organizations have established standards for facility accreditation, and professional associations have developed clinical guidelines. While abortions have been performed in office setting for decades, states have also enacted laws requiring that facilities that perform abortions meet specific requirements. The extent to which facility requirements have an impact on patient outcomes-for any procedure-is unclear.Methods and findingsWe conducted a systematic review to examine the effect of outpatient facility type (ASC vs. office) and specific facility characteristics (e.g., facility accreditation, emergency response protocols, clinician qualifications, physical plant characteristics, other policies) on patient safety, patient experience and service availability in non-hospital-affiliated outpatient settings. To identify relevant research, we searched databases of the published academic literature (PubMed, EMBASE, Web of Science) and websites of governmental and non-governmental organizations. Two investigators reviewed 3049 abstracts and full-text articles against inclusion/exclusion criteria and assessed the quality of 22 identified articles. Most studies were hampered by methodological challenges, with 12 of 22 not meeting minimum quality criteria. Of 10 studies included in the review, most (6) examined the effect of facility type on patient safety. Existing research appears to indicate no difference in patient safety for outpatient procedures performed in ASCs vs. physician offices. Research about specific facility characteristics is insufficient to draw conclusions.ConclusionsMore and higher quality research is needed to determine if there is a public health problem to be addressed through facility regulation and, if so, which facility characteristics may result in consistent improvements to patient safety while not adversely affecting patient experience or service availability.
