DR. TASIAN'S KIDNEY STONE RESEARCH RECEIVES WIDESPREAD MEDIA COVERAGE
The incidence of kidney stones (nephrolithiasis) among children has increased dramatically over the last 25 years for reasons that are not well described. This rapid rise in the prevalence of pediatric nephrolithiasis has resulted in uncertainty of how to best evaluate children with suspected kidney stones and how to effectively decrease recurrence for patients whose first stone developed during childhood. Dr. Tasian's research program addresses these knowledge gaps.
Dr. Tasian's research on the effect of temperature on kidney stone presentation has recently been featured on NBC-Harrisburg and 6ABC and received widespread international media coverage.
He and his colleagues found that the risk of presenting with kidney stones increased as the daily temperature rose above 82°F, and also increased at low temperatures (<40°F) in cities with colder climates (ref 1). This increased risk was likely due to dehydration caused by increased insensible water loss and decreased thirst responses at hot and cold temperatures, respectively. He is currently investigating the difference in the effect of temperature on kidney stone presentation between adults and children, who are more vulnerable to temperature extremes. In order to offset the adverse effects of temperature on stone risk, Dr. Tasian is also developing interventions to improve adherence to water intake -- an effective, inexpensive, and safe treatment that decreases kidney stone recurrence.
Dr. Tasian is also investigating ways to decrease unnecessary radiation exposure for children with kidney stones. In a collaboration with the NIH-supported Urologic Diseases in America Project, which includes investigators from UCLA and the RAND Corporation, Dr. Tasian demonstrated that use of CT as the initial imaging study for children with kidney is common in the United States despite guidelines that recommend ultrasound as the initial imaging study for children with suspected nephrolithiasis (ref 2). Dr. Tasian and colleagues from CHOP also found that the presence of clinical pathways that use ultrasound as the first imaging study for children with suspected nephrolithiasis was associated with decreased CT utilization (ref 3). They are actively investigating if these pathways reduce CT and increase ultrasound use in the Emergency Department.

CPCE and PolicyLab jointly host a seminar series that consists of Works-In-Progress sessions as well as visiting and faculty speakers' presentations.
Works-in-Progress sessions bring together health services researchers from across the hospital to discuss research projects that are in various stages of development, from protocol development all the way to data analysis, interpretation, and publication. CHOP Faculty and fellows who would like to receive feedback on their research are welcome to present. We offer 2 formats for Works in Progress sessions, Protocol Development sessions and Research Seminars. Protocol Development sessions are held at 3535 Market St., in room 1538a, and are open to CPCE and PolicyLab faculty and fellows and the research team of the presenter.
Research seminars are also held at 3535 Market St. on the 16th floor in conference room "A" or an equivalent large conference room. All interested CHOP faculty, fellows, and research staff are invited to attend research seminars.
Faculty Seminars provide a forum for CHOP faculty to present their research to the CHOP community. The goals of the Seminars are (1) To educate CHOP faculty and staff on state of the art knowledge of best practices in the management of pediatric conditions or development of health policy, and (2) To introduce some methodological concepts used in research elucidating best practices (e.g. basic statistical and study design issues).
Visiting Speaker seminars
Visiting speakers' presentations consist of nationally recognized health research lecturers speaking on topics of general interest to researchers and clinicians. These sessions are offered 2 to 3 times per year, and are generally held on the CHOP Main campus, usually in the Abramson or Colket building. These sessions are open to all CHOP faculty as well as research and clinical staff. Lunch is served at all seminars.
If you have questions about the CPCE and PolicyLab Seminar Series, would like to present at one of our seminars, or have a recommendation for a faculty or visiting speaker, please email CPCE@email.chop.edu.
CPCE and PolicyLab Faculty and Visiting Speaker Seminars qualify for Category 2 CME credit. CHOP faculty members can obtain documentation of their CME credits completed at CHOP by visiting the CHOP Continuing Medical Education site.
Pilot Grant Program
CPCE offers awards twice each year through its Pilot Grant Program. The purpose of this program is to promote and support CHOP investigators in clinical effectiveness pilot research studies that will attract external support for large-scale studies. Investigators from all CHOP departments and divisions, including fellows in their final year of fellowship transitioning to a faculty position at CHOP, are encouraged to apply. Selected proposals will be supported for up to a maximum of $10,000 for one year. Projects should be able to be completed within one year.
Application and Submission Process:
- Please submit proposals in NIH format to include project summary/abstract, specific aims, and a research strategy section which includes significance, innovation and approach. (5 page maximum)
- Proposals must also include a cover page, an investigator biosketch in NIH format and project budget, budget justification, and references. (not included in 5 page maximum)
- Budgets must be reviewed by your business manager prior to submission.
- Funding may not be used for investigator salary support. Staff salaries are allowable budget items.
- There are two submission deadlines per year. The 2015 deadlines are Wednesday, April 1 (awards announced in mid-May) and Thursday, October 1 (awards announced in mid-November).
- Selected applications must show documentation of IRB submission within 30 days of award notification.
- Proposals submitted for other awards (e.g., Foerderer) are not eligible for CPCE pilot grant consideration.
- Please submit the proposal as a single Word document via email to Deb Hillman, at Hillman@email.chop.edu no later than 4:00 p.m. on the deadline date.

Review Process and Selection Criteria
As detailed above, the review process will consist of two rounds. Applications meeting the definitions (above) for pilot clinical effectiveness research studies, and judged by the Pilot Grant Steering Committee to be of sufficient quality for further review, will be assigned to a reviewer, critiqued and scored. Reviewers will meet in a study section to discuss the merits and limitations of the competing proposals and to determine the awardee(s). All applicants whose proposals qualify for round two will receive a copy of reviewers' comments and score. Those applications that do not qualify for round two will be returned to the applicant without further review, critique or score.
The following criteria will be used to score the proposals. They are adapted from NIH Study Section Criteria.
- Significance of Study: Does the project address an important problem or a critical barrier to progress in the field?
- Approach: Are the overall strategy, methodology, and analyses well-reasoned and appropriate to accomplish the specific aims of the project? Are potential problems, alternative strategies, and benchmarks for success presented?
- Likelihood of Impact of Clinical Effectiveness: If the aims of the project are achieved, how will scientific knowledge, technical capability, and/or clinical practice be improved? How will successful completion of the aims change the concepts, methods, technologies, treatments, services, or preventative interventions that drive this field?
- Appropriateness of Budget: Is the proposed budget and period of support appropriate in relation to the proposed research?
- Likelihood of Future Research: If the aims of the project are achieved, will the results lend themselves to future research?
- Innovation: Does the application challenge and seek to shift current research or clinical practice paradigms by utilizing novel theoretical concepts, approaches or methodologies, instrumentation, or interventions? Are the concepts, approaches or methodologies, instrumentation, or interventions novel to one field of research or novel in a broad sense? Is a refinement, improvement, or new application of theoretical concepts, approaches or methodologies, instrumentation, or interventions proposed?
The above criteria will be scored on a scale from 1 (high impact) to 9 (low impact).
Common Pitfalls of Past CPCE Pilot Grant Applications:
- Failure to anticipate difficulties or address limitations
- Uncertainty regarding future direction or funding
- Incomplete significance section; failure to adequately describe rationale
- Overambitious for pilot study; unrealistic timeline
- (Budget) Underestimate of biostatistical support needed to complete aims
Although projects may be funded up to a maximum of $10,000 priority will be given to those projects that include a prudent spending plan. CPCE will attempt to fund all requested budgets in full, but may elect to partially fund certain protocols in order to increase the number of funded proposals.
- Principal investigators must submit a report at the end of the grant period for review by the Pilot Grant Program steering committee. The reports should include progress, expenditures and plans for disseminating results. Subsequent reports will be requested to include publications and extramural funding resulting from the research.
- Funds unspent at the end of the one-year grant period will be returned to CPCE. However, requests for rollover of funds for an additional year will be considered with adequate justification. We are very excited about the opportunity to support fellows and junior faculty who are interested in advancing CPCE's goals.

IRB APPROVAL FOR STUDIES THAT UTILIZE HAU SERVICES
The IRB has increasingly judged large datasets, such as those obtained from PHIS, to contain data that is not readily identifiable and therefore, outside the requirements for prospective IRB review and approval. Regulatory statements have made clear that "readily identifiable" does not mean possibly or potentially identifiable. This lowers the barriers for receipt and use of these datasets.
HIPAA does apply to the receipt/use of these datasets.
- If the dataset is a limited dataset, then all that is required to obtain and use it would be a data use agreement (no IRB approval required) with the data source (e.g. CHCA for PHIS data).
For research that utilizes datasets containing identifiable PHI, or for which data will be prospectively collected, IRB review/approval will continue to be needed.
It is the responsibility of the investigator to obtain IRB review and approval for those studies that require it, and to complete any data use agreements required by the data source.
For more complete information regarding what must be reviewed by the IRB, the use of registries/repositories for research, and other related topics, please see these sections of the research intranet site (authentication may be required):
SUBMITTING MANUSCRIPTS BASED ON RESEARCH UTILIZING DE-IDENTIFIED OR LIMITED DATASETS
When submitting a manuscript for publication, for a study that utilized PHIS or a comparable large and not readily identifiable dataset, and which therefore did not require IRB review/approval, the following boilerplate text can be used when needed during the journal's submission process. There are two versions, please choose the appropriate one, depending on the nature of your dataset.
1) In accordance with the Common Rule (45 CFR 46.102(f)) and the policies of the The Children's Hospital of Philadelphia IRB, this research, which utilized a de-identified dataset, was determined to not meet the definition of human subjects research.
2) In accordance with the Common Rule (45 CFR 46.102(f)) and the policies of the The Children's Hospital of Philadelphia IRB, this research, which utilized a limited dataset according to the terms of a valid data use agreement, was determined to not meet the definition of human subjects research.
