A Randomized Controlled Trial of a Mobile Health Intervention to Promote Self-Management After Lung Transplantation. Am J Transplant 2016; 16:2172-80. [PMID: 26729617 PMCID: PMC4925283 DOI: 10.1111/ajt.13701] [Citation(s) in RCA: 84] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2015] [Revised: 12/17/2015] [Accepted: 12/27/2015] [Indexed: 01/25/2023]
Abstract
Lung transplant recipients are encouraged to perform self-management behaviors, including (i) monitoring health indicators, (ii) adhering to their regimen, and (iii) reporting abnormal health indicators to the transplant coordinator, yet performance is suboptimal. When hospital discharge was imminent, this two-group trial randomized 201 recipients to use either the mobile health (mHealth) intervention (n = 99) or usual care (n = 102), to compare efficacy for promoting self-management behaviors (primary outcomes) and self-care agency, rehospitalization, and mortality (secondary outcomes) at home during the first year after transplantation. The mHealth intervention group performed self-monitoring (odds ratio [OR] 5.11, 95% confidence interval [CI] 2.95-8.87, p < 0.001), adhered to medical regimen (OR 1.64, 95% CI 1.01-2.66, p = 0.046), and reported abnormal health indicators (OR 8.9, 95% CI 3.60-21.99, p < 0.001) more frequently than the usual care group. However, the two groups did not differ in rehospitalization (OR 0.78, 95% CI 0.36-1.66, p = 0.51) or mortality (hazard ratio 1.71, 0.68-4.28, p = 0.25). The positive impact of the mHealth intervention on self-management behaviors suggests that the intervention holds promise and warrants further testing.

Abstract
BACKGROUND Despite the proliferation of health information technology (IT) interventions, descriptions of the unique considerations for conducting randomized trials of health IT interventions intended for patient use are lacking. PURPOSE Our purpose is to describe the protocol to evaluate Pocket PATH (Personal Assistant for Tracking Health), a novel health IT intervention, as an exemplar of how to address issues that may be unique to a randomized controlled trial (RCT) to evaluate health IT intended for patient use. METHODS An overview of the study protocol is presented. Unique considerations for health IT intervention trials and strategies are described to maintain equipoise, to monitor data safety and intervention fidelity, and to keep pace with changing technology during such trials. LESSONS LEARNED The sovereignty granted to technology, the rapid pace of changes in technology, ubiquitous use in health care, and obligation to maintain the safety of research participants challenge researchers to address these issues in ways that maintain the integrity of intervention trials designed to evaluate the impact of health IT interventions intended for patient use. CONCLUSIONS Our experience evaluating the efficacy of Pocket PATH may provide practical guidance to investigators about how to comply with established procedures for conducting RCTs and include strategies to address the unique issues associated with the evaluation of health IT for patient use.

Abstract
Lung Volume Reduction Surgery (LVRS) has become a palliative treatment for patients with advanced emphysema and disabling dyspnea. After single lung transplantation in chronic obstructive pulmonary disease, LVRS may be indicated to improve graft dysfunction caused by native lung hyperinflation compressing the grafted lung. This common complication is the subject of our study, which showed LVRS to be helpful to manage this situation. We performed an observational retrospective and descriptive study using the data of 293 patients transplanted in our center between January 1996 and October 2011. Some of the patients who underwent a single lung transplantation developed native lung hyperinflation years after the transplantation, interfering with respiratory function due to graft compression.

Abstract
The number of patients awaiting lung transplantation has steadily increased over the past decade, but the number of donors has remained relatively stable. Owing to the increasing scarcity of donor lungs, especially for pediatric and small adult recipients, advanced operative strategies for the use of larger grafts for smaller recipients have been developed. Size matching between donors and recipients represents one of the organ distribution criteria widely accepted by lung transplantation teams. However, in some cases it is not possible to allocate a donor to the corresponding size-compatible recipient. To avoid possible complications derived from the implantation of oversized lungs into smaller recipients, various methods of downsizing are applied for cadaveric donor lungs, such as lobar transplantation. We review our experience in 6 patients undergoing volume reduction of the lung graft by lobar resection at the time of transplantation. Graft volume reduction by anatomic resection (lobar transplantation) is a reliable and safe procedure to overcome size disparities between the donor and the recipient of a lung transplant, and thus to maximize the number of donors.

Abstract
BACKGROUND Advanced recipient age is reported to negatively affect survival after lung transplantation (LTX). We hypothesized that LTX in patients aged > or = 60 years could be performed with acceptable outcomes. METHODS We identified 182 consecutive LTX recipients from 1995 to 2005. Outcomes were analyzed and survival compared with results in recipients aged < 60, as well as with United Network for Organ Sharing (UNOS) registry outcomes for the same age and study period. Actuarial survivals were calculated by the Kaplan-Meier method. RESULTS During the study period, 29% (52/182) of LTX recipients were > or = 60 years old (range, 60 to 69 years). Median follow-up was 2.9 years (range, 0 to 10 years). All patients but one received a single lung. Indications included chronic obstructive pulmonary disease in 63% (33/52), idiopathic pulmonary fibrosis in 27% (14/52), and other in 10% (5/52). In-hospital mortality was 12% (6/52) for those aged > or = 60 compared with 7% (9/130) for those aged < 60 (p = NS). Complications included reoperation in 10% (5/52), requirement for extracorporeal membrane oxygenation in 6% (3/52), renal failure in 12% (6/52), and stroke in 4% (2/52). Actuarial survivals at 30 days, and 1, 3, and 5 years were 90% (82, 98), 86% (76, 96), 71% (56, 85), and 55% (37, 73), respectively. No significant difference in survival was observed between age cohorts for our institutional data by Kaplan-Meier analysis (p = 0.34) or by Cox proportional hazard model (p = 0.15). A significant survival advantage was noted for our institution compared with UNOS for this cohort (p = 0.018). CONCLUSIONS In carefully selected recipients > or = 60 years of age, LTX offers acceptable outcomes and survival.

Abstract
INTRODUCTION We started lung transplantation (LT) in October 1993 and review the status of recipients who have survived beyond 5 years. METHODS A retrospective review of patients undergoing LT from October 1993 to October 1998 included pulmonary function data, incidence of bronchiolitis obliterans syndrome (BOS), functional status, and survival. RESULTS Of 73 transplantations 41 (56%) patients have survived beyond 5 years (study group), including 23 men and 18 women of age 33.2 +/- 15.6 years. Indications for LT were as follows: cystic fibrosis (n = 16), emphysema (n = 13), pulmonary fibrosis (n = 8), and other (n = 4). Actuarial survival at 5, 7, and 9 years was 56%, 53%, and 43%, respectively. Freedom from BOS was 63%, 56%, and 50% at 5, 7, and 9 years, respectively. The median percent predicted FEV1 was 67%, 56%, and 56%, respectively. Also, 79% of recipients had no limitations in their daily activities; 65% were active and working. Only 5% of patients showed some degree of limitation at 5 years posttransplantation. When survivors beyond 5 years were compared with nonsurvivors beyond 5 years, differences were observed: nonsurvivors more frequently required bypass (P = .01), experienced longer postoperative intubation times (P = .01), and exhibited lower PaO2 at 12 months posttransplantation (P < .01). CONCLUSION Our data show good survival rates among patients surviving beyond 5 years after LT, with a moderate incidence of BOS at 9 years posttransplantation. Despite the incidence of BOS, these patients have good pulmonary function and activity status.

Abstract
INTRODUCTION Pediatric lung transplantation (LT) was started in Spain in 1996 at our institution. We compare the results of pediatric LT with those in adult patients. METHODS A retrospective review of LT patients from 1993 to 2003 included demographic donor and recipient data, pulmonary function, gas exchange parameters, complications, episodes of rejection and pneumonia, as well as survival. Patients were divided into 2 groups: pediatric (<16 years) and adult (>16 years) LT patients. RESULTS Of 165 LTs performed, 23 recipients were pediatric patients (10 boys, 13 girls; mean age, 11.9 +/- 2.9 years [range, 5-16 years]). The indications were cystic fibrosis (n = 21), pulmonary fibrosis (n = 1), and Kartagener syndrome (n = 1). The actuarial survival rate was 73%, 67%, and 62% at 1, 3, and 8 years post-LT in children, versus 67%, 56%, and 41% at 1, 3, and 8 years post-LT in adult patients (P = NS). Of the pediatric patients, 35% required mechanical ventilation preoperatively (P < .001). Pediatric patients showed a higher incidence of pneumonia (P < .01) and acute rejection episodes (P = .02) during the first month post-LT, and longer stays in the intensive care unit (P = .02). Pediatric patients displayed more immunosuppression-related adverse effects: diabetes (P = .04), neuropathy (P < .01), and hirsutism (P < .001). In children, arterial oxygen tension improved, from 51 mm Hg pre-LT to 93 mm Hg at 5 years post-LT. Forced expiratory volume in 1 second improved from 28% pre-LT to 84% at 5 years post-LT. CONCLUSION In children, LT is a high-risk procedure because of the critical status of these patients. However, the results of pediatric LT are similar to those in adults, but with better long-term survival.

Abstract
Size matching between donors and recipients represents one of the organ distribution criteria widely accepted by lung transplant teams. However, in some cases it is not possible to allocate a donor to the corresponding size-compatible recipient. To avoid possible complications derived from the implantation of oversized lungs into smaller recipients, surgical procedures such as pulmonary tailoring and lobar transplantation have been advocated. We review our experience in 13 patients undergoing volume reduction of the lung graft at the time of transplantation, either by nonanatomical lung volume reduction or by lobar transplantation. There were no significant differences between lung-downsized patients and standard lung transplantation patients in terms of donor characteristics, surgical and postoperative complications, functional outcome, and survival. We conclude that downsizing the lung graft either by nonanatomical resection or lobar transplantation is safe and reliable to overcome size disparities between donor and recipients, with no additional morbidity and with similar early and midterm outcomes to those in standard lung transplants.

Abstract
The purpose of this paper is to describe the psychosocial process of the symptom experience associated with the threat of organ rejection after lung transplantation. A grounded theory approach, including theoretical sampling and constant comparative analyses, was used in a sample of 14 lung transplant recipients who varied in age, gender, underlying lung disease, experience with rejection, and time since transplantation. 'Striving for normalcy' was the core process linking each of the four stages of the symptom experience and interpretation: naïveté, vulnerability, discovery, and insight. Each stage was marked by an initiating event, a predictable symptom response, and a dialectic (an internal struggle between recipients' personal perceptions of the situation and the juxtaposed understandings of the situation that they gleaned from transplant clinicians). Each stage was also labeled with a descriptor of the aspect of striving for normalcy that accounted for the variation in the symptom responses that recipients exhibited, the dialectics they faced, and the exemplars for each stage of the process. During the stage of naïveté, recipients were elated at improvements after transplantation, and often denied or delayed reporting symptoms. Once they experienced a rejection episode they entered the stage of vulnerability and became more vigilant about symptoms. The discovery stage was marked by the realization that rejection lacked characteristic symptoms; therefore, it was important to recognize any changes from their baseline condition. Recipients who achieved the insight stage realized that until they gave up some independence in exchange for interdependence, extended periods of normalcy eluded them, and embraced a reciprocal relationship with the transplant team. Knowledge that recipients' experience evolves over time from furtive hope during the stage of naïveté to qualified hope during the insight stage, directs us to intervene using stage-specific interventions to promote better symptom recognition and reporting.

Abstract
Since international recommendations for lung transplant recipients were made in 1998, newer tools for predicting mortality in patients who have end-stage lung disease have been investigated. This article reviews studies for predicting mortality in obstructive, restrictive, pulmonary vascular, and suppurative/bronchiectatic lung disease. Newer considerations for alternative treatments, postoperative risks, and contraindications are also examined. The article aims to provide more accurate data for selecting patients who will benefit from lung transplantation.

Abstract
Interstitial lung disease is a heterogeneous group of illnesses, some of which may progress to a fibrosing stage and cause respiratory failure. For selected candidates, lung transplantation is the ultimate therapeutic option. We review data on lung transplantation for various interstitial lung diseases. We address indications, procedures, and outcomes for patients undergoing transplantation. Unique issues affecting morbidity, mortality, and recurrence of disease are discussed. We review the literature of transplantation for specific interstitial lung diseases and the outcomes of transplantation for interstitial lung diseases. Candidates with idiopathic pulmonary fibrosis experience high mortality on the waiting list, but derive significant survival benefit from lung transplantation. Recurrence is reported for several interstitial lung diseases after lung transplantation. Survival with lung transplantation for interstitial lung diseases is comparable with that attained in recipients with other indications. Lung transplantation is a well-tolerated, effective therapy for respiratory failure in interstitial lung disease.
