Patient and Stakeholder Engagement in the PCORI Pilot Projects: Description and Lessons Learned

BACKGROUND

Patients and healthcare stakeholders are increasingly becoming engaged in the planning and conduct of biomedical research. However, limited research characterizes this process or its impact.

OBJECTIVE

We aimed to characterize patient and stakeholder engagement in the 50 Pilot Projects funded by the Patient-Centered Outcomes Research Institute (PCORI), and identify early contributions and lessons learned.

DESIGN

A self-report instrument was completed by researchers between 6 and 12 months following project initiation.

PARTICIPANTS

Forty-seven principal investigators or their designees (94 % response rate) participated in the study. MAIN MEASURES Self-report of types of stakeholders engaged, stages and levels of engagement, facilitators and barriers to engagement, lessons learned, and contributions from engagement were measured.

KEY RESULTS

Most (83 %) reported engaging more than one stakeholder in their project. Among those, the most commonly reported groups were patients (90 %), clinicians (87 %), health system representatives (44 %), caregivers (41 %), and advocacy organizations (41 %). Stakeholders were commonly involved in topic solicitation, question development, study design, and data collection. Many projects engaged stakeholders in data analysis, results interpretation, and dissemination. Commonly reported contributions included changes to project methods, outcomes or goals; improvement of measurement tools; and interpretation of qualitative data. Investigators often identified communication and shared leadership strategies as "critically important" facilitators (53 and 44 % respectively); lack of stakeholder time was the most commonly reported challenge (46 %). Most challenges were only partially resolved. Early lessons learned included the importance of continuous and genuine partnerships, strategic selection of stakeholders, and accommodation of stakeholders' practical needs.

CONCLUSIONS

PCORI Pilot Projects investigators report engaging a variety of stakeholders across many stages of research, with specific changes to their research attributed to engagement. This study identifies early lessons and barriers that should be addressed to facilitate engagement. While this research suggests potential impact of stakeholder engagement, systematic characterization and evaluation of engagement at multiple stages of research is needed to build the evidence base.

Learning from health information exchange technical architecture and implementation in seven beacon communities

As health care providers adopt and make “meaningful use” of health information technology (health IT), communities and delivery systems must set up the infrastructure to facilitate health information exchange (HIE) between providers and numerous other stakeholders who have a role in supporting health and care. By facilitating better communication and coordination between providers, HIE has the potential to improve clinical decision-making and continuity of care, while reducing unnecessary use of services. When implemented as part of a broader strategy for health care delivery system and payment reform, HIE capability also can enable the use of analytic tools needed for population health management, patient engagement in care, and continuous learning and improvement. The diverse experiences of seven communities that participated in the three-year federal Beacon Community Program offer practical insight into factors influencing the technical architecture of exchange infrastructure and its role in supporting improved care, reduced cost, and a healthier population. The case studies also document challenges faced by the communities, such as significant time and resources required to harmonize variations in the interpretation of data standards. Findings indicate that their progress developing community-based HIE strategies, while driven by local needs and objectives, is also influenced by broader legal, policy, and market conditions.

Evaluation design and technical assistance opportunities: early findings from the Beacon Community Program evaluation teams

The Beacon Community Cooperative Agreement Program is funding 17 communities to build and strengthen their health information technology (IT) capabilities to enhance care coordination, improve patient and population health, and reduce or restrain costs. Based on the experiences and evidence generated by these communities, the program hopes to illustrate the possibilities of leveraging health IT to achieve desired goals. Doing so requires rigorous evaluation work, which is the subject of this issue brief. Based on semistructured interviews with representatives from each Beacon Community, the brief outlines various study designs, evaluation approaches, outcome measures, and data sources in use. It also identifies some common challenges, including establishing governance models, determining baseline measures, and assessing impact in a relatively constrained timeframe. Technical assistance in disseminating and publishing findings and assessing return on investments will be offered in the coming year.

Multidetector spiral CT renal angiography in the diagnosis of giant renal artery aneurysms

A case of giant renal artery aneurysm in a 63-year-old man is presented. Renal artery aneurysms are rare (incidence < 1%) and this case is one of the largest giant renal artery aneurysms recorded in the literature. This case also demonstrates the value of multidetector spiral computed tomographic renal angiography in the diagnosis, planning, and treatment of renal aneurysms.

The influence of acute hypothermia on renal function of anaesthetized euthermic and acclimatized rats

Acute hypothermia has a major impact on cardiovascular control and renal function, but the extent to which these can be correlated with and influenced by changes in the altered pattern of sympathetic outflow to the kidneys is unclear. Moreover, it is unknown whether these responses to acute hypothermia are altered by chronic cold exposure and this study aimed to examine these factors. Renal function and renal sympathetic nerve activity (RSNA) were measured in male Wistar rats, euthermic (control) or acclimatized (exposed to progressively lower environmental temperature and photoperiod over 8 weeks), anaesthetized with chloralose/urethane. Reduction of core temperature (Tc) to 25 degrees C caused approximately 40% reduction in heart rate (HR), approximately 10% fall in mean arterial blood pressure (MABP), and decreased glomerular filtration rate (GFR) by approximately 50% and approximately 5% in euthermic and acclimatized rats, respectively. At 25 degrees C, urine flow increased some two-fold and absolute and fractional sodium excretions by 4- to 6-fold in the euthermic rats and to a lesser extent in the cold acclimatized rats, while basal levels of fluid excretion were higher in the acclimatized rats. A loss of pulsatility in the RSNA signal with cooling was seen in both groups. One of the factors contributing to modest hypotension during acute hypothermia is a reduction in RSNA. There was a progressive fall in the proportion of RSNA power at HR frequency with cooling of 20% in euthermic and 80% in acclimatized rats. All variables were restored to basal levels on rewarming in both groups of rats. We conclude that natriuresis and diuresis in euthermic rats during hypothermia is a consequence of a reduction in nephron reabsorption, reduced urine osmolality and possibly altered patterning of RSNA. In acclimatized rats, the response was modified by altered renal haemodynamics and/or hormonal influences induced by chronic cold exposure to minimize the hypothermic stress on renal function.

Effect of hypothermia on baroreflex control of heart rate and renal sympathetic nerve activity in anaesthetized rats

The present study investigated the effect of acute hypothermia on baroreflex control of heart rate (HR) and renal sympathetic nerve activity (RSNA) by generating baroreflex logistic function curves, using bolus doses of phenylephrine and sodium nitroprusside, in anaesthetized male Wistar rats at a core temperature (T(b)) of 37 degrees C, during acute severe hypothermia at T(b)= 25 degrees C and on rewarming to 37 degrees C. Comparisons were made between rats without (euthermic, n= 6) and with (acclimated, n= 7) prior exposure to lower ambient temperatures and shorter photoperiod, simulating adaptation to winter conditions. In both groups of rats, acute hypothermia to T(b)= 25 degrees C shifted the baroreflex-RSNA curve slightly leftwards and downwards with decreases in the setpoint pressure and maximal gain, whereas it markedly impaired the baroreflex-HR curve characterized by decreases in response range by approximately 90% (P < 0.001), minimum response by approximately 10% (P < 0.05) and maximum gain by approximately 95% (P < 0.001), from that at T(b)= 37 degrees C. All parameters were restored to precooling levels on rewarming. Electrical stimulation of cardiac vagal efferents induced a voltage-related bradycardia, the magnitude of which was partially reduced during acute hypothermia, and there was a significant prolongation of the electrocardiogram intervals indicating a delay in cardiac conduction. Mild suppression of baroreflex control of RSNA could contribute to hypothermic hypotension and may primarily reflect an effect of T(b) on central drive. The marked attenuation of the baroreflex control of HR during hypothermia was likely to be due to an impairment of both the central and peripheral components of the reflex arc. Baroreflex control of RSNA and HR was similar between both groups of rats, which implied that the control was non-adaptive on chronic cold exposure.
