Identifying Health Facilities outside the Enterprise: Challenges and Strategies for Supporting Health Reform and Meaningful Use

Objective: To support collation of data for disability determination, we sought to accurately identify facilities where care was delivered across multiple, independent hospitals and clinics. Methods: Data from various institutions' electronic health records were merged and delivered as continuity of care documents to the United States Social Security Administration (SSA). Results: Electronic records for nearly 8000 disability claimants were exchanged with SSA. Due to the lack of standard nomenclature for identifying the facilities in which patients received the care documented in the electronic records, SSA could not match the information received with information provided by disability claimants. Facility identifiers were generated arbitrarily by health care systems and therefore could not be mapped to the existing international standards. Discussion: We propose strategies for improving facility identification in electronic health records to support improved tracking of a patient's care between providers to better serve clinical care delivery, disability determination, health reform and meaningful use. Conclusion: Accurately identifying the facilities where health care is delivered to patients is important to a number of major health reform and improvement efforts underway in many nations. A standardized nomenclature for identifying health care facilities is needed to improve tracking of care and linking of electronic health records

The aging endoplasmic reticulum

Hallmarks of aging include the accumulation of aberrant proteins and a lower resistance to stresses. Because the endoplasmic reticulum (ER) functions to fold proteins and possesses unique stress sensing pathways, the central hypothesis of this dissertation is that the ER is a target of cellular aging and significantly underlies these age-related phenotypes. This hypothesis was tested using isolated microsomes from young (3-6 mo) and old (24-26 mo) rats and a novel primary hepatocyte cell culture model that maintains the aging phenotype. The ER luminal oxidation/reduction (redox) environment, exemplified by the glutathione redox ratio (GSH:GSSG), is vital for both ER stress signaling and the regulation of ER oxidoreductase activity. Therefore, the hepatic microsomal GSH:GSSG ratio from young and old rats was determined. Our results showed that the GSH:GSSG ratio in young rats was 3.8:1 and that, in contrast to the age-related loss of GSH redox in whole liver, microsomal GSH:GSSG increased to 6.4:1 in old rats. This increase is sufficient to convert ER oxidoreductases from folding proteins to enzymes involved in protein unfolding. These results show that the ER is under an increased stress with age, yet no activation of ER stress response pathways was detected. Using the aging cell culture model noted above to examine the loss of ER stress response with age, we show that following induction of an ER stress by tunicamycin, ER-mediated "pro-apoptotic" pathways were in intact with age, but induction of "pro-survival" genes were significantly delayed. Taken together, these show that aging leads to: 1) a reductive shift in ER thiol redox, and 2) an attenuation of ER stress response. Lastly, previous work showed that (R)-alpha-lipoic acid (R-LA) restores GSH levels and redox status in aged rat livers. To determine whether R-LA also reversed the age-related changes in ER GSH redox status, young and old rats were supplemented with R-LA. Results showed that R-LA reversed both the age-related increase in the ER GSH redox state and induced protective ER stress response pathways in a manner similar to young animals. Thus, R-LA may be an effective therapeutic to maintain ER homeostatic mechanisms with age

Improving Medication Adherence for Chronic Disease Using Integrated e-Technologies

Diabetes mellitus (DM) is a chronic disease affecting more than 285 people worldwide and the fourth leading cause of death. Increasing evidence suggests that many DM patients have poor adherence with prescribed medication therapies, impacting clinical outcomes. Patients' barriers to medication adherence and the extent to which barriers contribute to poor outcomes, however, are not routinely assessed. We designed a dashboard for an electronic health record system to integrate DM disease and medication data, including patient-reported barriers to adherence. Processes to support routine capture of data from patients are also being explored. The dashboard is being evaluated at multiple ambulatory clinics to examine whether integrated electronic tools can support patient-centered decision-making processes involving complex medication regimens for DM and other chronic diseases

Toward Timely Data for Cancer Research: Assessment and Reengineering of the Cancer Reporting Process

Background Cancer registries systematically collect cancer-related data to support cancer surveillance activities. However, cancer data are often unavailable for months to years after diagnosis, limiting its utility. Objective The objective of this study was to identify the barriers to rapid cancer reporting and identify ways to shorten the turnaround time. Methods Certified cancer registrars reporting to the Indiana State Department of Health cancer registry participated in a semistructured interview. Registrars were asked to describe the reporting process, estimate the duration of each step, and identify any barriers that may impact the reporting speed. Qualitative data analysis was performed with the intent of generating recommendations for workflow redesign. The existing and redesigned workflows were simulated for comparison. Results Barriers to rapid reporting included access to medical records from multiple facilities and the waiting period from diagnosis to treatment. The redesigned workflow focused on facilitating data sharing between registrars and applying a more efficient queuing technique while registrars await the delivery of treatment. The simulation results demonstrated that our recommendations to reduce the waiting period and share information could potentially improve the average reporting speed by 87 days. Conclusions Knowing the time elapsing at each step within the reporting process helps in prioritizing the needs and estimating the impact of future interventions. Where some previous studies focused on automating some of the cancer reporting activities, we anticipate much shorter reporting by leveraging health information technologies to target this waiting period

Regional data exchange to improve care for veterans after non-VA hospitalization: a randomized controlled trial

BACKGROUND: Coordination of care, especially after a patient experiences an acute care event, is a challenge for many health systems. Event notification is a form of health information exchange (HIE) which has the potential to support care coordination by alerting primary care providers when a patient experiences an acute care event. While promising, there exists little evidence on the impact of event notification in support of reengagement into primary care. The objectives of this study are to 1) examine the effectiveness of event notification on health outcomes for older adults who experience acute care events, and 2) compare approaches to how providers respond to event notifications. METHODS: In a cluster randomized trial conducted across two medical centers within the U.S. Veterans Health Administration (VHA) system, we plan to enroll older patients (≥ 65 years of age) who utilize both VHA and non-VHA providers. Patients will be enrolled into one of three arms: 1) usual care; 2) event notifications only; or 3) event notifications plus a care transitions intervention. In the event notification arms, following a non-VHA acute care encounter, an HIE-based intervention will send an event notification to VHA providers. Patients in the event notification plus care transitions arm will also receive 30 days of care transition support from a social worker. The primary outcome measure is 90-day readmission rate. Secondary outcomes will be high risk medication discrepancies as well as care transitions processes within the VHA health system. Qualitative assessments of the intervention will inform VHA system-wide implementation. DISCUSSION: While HIE has been evaluated in other contexts, little evidence exists on HIE-enabled event notification interventions. Furthermore, this trial offers the opportunity to examine the use of event notifications that trigger a care transitions intervention to further support coordination of care.

Measuring agreement between decision support reminders: the cloud vs. the local expert

Background: A cloud-based clinical decision support system (CDSS) was implemented to remotely provide evidence-based guideline reminders in support of preventative health. Following implementation, we measured the agreement between preventive care reminders generated by an existing, local CDSS and the new, cloud-based CDSS operating on the same patient visit data. Methods: Electronic health record data for the same set of patients seen in primary care were sent to both the cloud-based web service and local CDSS. The clinical reminders returned by both services were captured for analysis. Cohen’s Kappa coefficient was calculated to compare the two sets of reminders. Kappa statistics were further adjusted for prevalence and bias due to the potential effects of bias in the CDS logic and prevalence in the relative small sample of patients. Results: The cloud-based CDSS generated 965 clinical reminders for 405 patient visits over 3 months. The local CDSS returned 889 reminders for the same patient visit data. When adjusted for prevalence and bias, observed agreement varied by reminder from 0.33 (95% CI 0.24 – 0.42) to 0.99 (95% CI 0.97 – 1.00) and demonstrated almost perfect agreement for 7 of the 11 reminders. Conclusions: Preventive care reminders delivered by two disparate CDS systems show substantial agreement. Subtle differences in rule logic and terminology mapping appear to account for much of the discordance. Cloud-based CDSS therefore show promise, opening the door for future development and implementation in support of health care providers with limited resources for knowledge management of complex logic and rules

Long-term implantation of acoustic transmitters induces chronic inflammatory cytokine expression in adult rainbow trout (Oncorhynchus mykiss)

Although the effects of surgically implanted transmitters on survival, tag retention, healing and growth have been studied, there has been little research regarding the potential immune response induced by these transmitters. In the current study, mature rainbow trout received either surgical implantation of an acoustic transmitter or a sham surgical procedure. These fish were then sampled over a 10-week period so that pro-inflammatory cytokine expression in the spleen, peritoneal cavity lymphocytes and muscle at the surgical site could be analyzed. There were no significant differences in transcript expression for the spleen and muscle tissue between fish that had a transmitter and those that received the surgical procedure alone. However, transmitter presence significantly increased the expression of IL-6, IL-1β and TNFα in the peritoneal cells at 10 weeks indicating that tagged fish may be coping with chronic inflammation. Furthermore, tagged male fish had a higher inflammatory response in 10-week peritoneal lavage samples when compared to their tagged mature female counterparts, providing some evidence that mature female rainbow trout may have suppressed immune function when sexually mature. Externally, fish appeared to heal at similar rates regardless of the presence or absence of the transmitter, but the tag itself was prone to encapsulation and adhesion to the body wall and/or surgical site. This suggests that fish tagged with large intraperitoneal implants may not behave similarly to their wild counterparts. This research could aid in the development of improved telemetry tags that are more biocompatible, economical and better able to track fish behavior/movement.Canada Research Council Research ChairNSERC Discovery Grant [217529

Healthcare providers’ beliefs and attitudes regarding risk compensation following HPV vaccination

Background Provider recommendation is a significant predictor of HPV vaccine uptake. Prior research suggests that concerns regarding risk compensation could cause some providers to hesitate recommending the HPV vaccine. Methods During 15–30 min semi-structured interviews in early 2015, 22 U.S. pediatric providers were asked about their beliefs regarding sexual risk compensation and cervical cancer screening following HPV vaccination. Providers were asked if these beliefs result in reservations recommending the vaccine. Interviews were audio-recorded, transcribed, and analyzed using inductive content analysis. Results None of the providers believed the HPV vaccine would result in risky sexual behavior. Half indicated it was better to start vaccination early, before sexual activity was a worry. Others noted that patients’ risky behavior decisions happen independently of vaccination. When providers were asked if they were concerned about decreased cervical cancer screening, half said they did not know and some stated they had never thought about it before. The main themes addressed were the significant time lapse between vaccination and screening and that women tend to get over-screened as opposed to under-screened. Conclusion Providers were generally in favor of HPV vaccination and do not perceive risk compensation as a barrier to HPV recommendation

A qualitative study of healthcare provider awareness and informational needs regarding the nine-valent HPV vaccine

The 9-valent Human Papillomavirus (HPV) vaccine, 9vHPV, was licensed in the U.S. in December, 2014. We assessed healthcare provider (HCP) awareness of the newly approved vaccine and identified questions HCPs have about the vaccine. As part of a larger study, we used semi-structured interviews to ask 22 pediatric HCPs about their awareness of 9vHPV, questions they have about the vaccine, and questions they anticipate from patients and parents. Interviews were audio-recorded and transcribed then analyzed using inductive content analysis. Over half were aware of the vaccine but few HCPs claimed to be familiar with it. HCPs indicated several questions with common themes pertaining to efficacy, side effects, and cost. Only half of HCPs believed patients or parents would have questions. The results suggest strategies and areas for health systems and public health organizations to target in order to resolve unmet educational needs among HCPs regarding 9vHPV
