Considerations for Integration of Perioperative Electronic Health Records Across Institutions for Research and Quality Improvement: The Approach Taken by the Multicenter Perioperative Outcomes Group.

Use of the electronic health record (EHR) has become a routine part of perioperative care in the United States. Secondary use of EHR data includes research, quality, and educational initiatives. Fundamental to secondary use is a framework to ensure fidelity, transparency, and completeness of the source data. In developing this framework, competing priorities must be considered as to which data sources are used and how data are organized and incorporated into a useable format. In assembling perioperative data from diverse institutions across the United States and Europe, the Multicenter Perioperative Outcomes Group (MPOG) has developed methods to support such a framework. This special article outlines how MPOG has approached considerations of data structure, validation, and accessibility to support multicenter integration of perioperative EHRs. In this multicenter practice registry, MPOG has developed processes to extract data from the perioperative EHR; transform data into a standardized format; and validate, deidentify, and transfer data to a secure central Coordinating Center database. Participating institutions may obtain access to this central database, governed by quality and research committees, to inform clinical practice and contribute to the scientific and clinical communities. Through a rigorous and standardized approach to ensure data integrity, MPOG enables data to be usable for quality improvement and advancing scientific knowledge. As of March 2019, our collaboration of 46 hospitals has accrued 10.7 million anesthesia records with associated perioperative EHR data across heterogeneous vendors. Facilitated by MPOG, each site retains access to a local repository containing all site-specific perioperative data, distinct from source EHRs and readily available for local research, quality, and educational initiatives. Through committee approval processes, investigators at participating sites may additionally access multicenter data for similar initiatives. Emerging from this work are 4 considerations that our group has prioritized to improve data quality: (1) data should be available at the local level before Coordinating Center transfer; (2) data should be rigorously validated against standardized metrics before use; (3) data should be curated into computable phenotypes that are easily accessible; and (4) data should be collected for both research and quality improvement purposes because these complementary goals bolster the strength of each endeavor.

Preconception counseling, fertility, and pregnancy complications after abdominal organ transplantation: a survey and cohort study of 532 recipients.

BACKGROUND: Pregnancy after solid organ transplant is a significant priority for transplant recipients but how patients report being counseled is unknown. METHODS: We performed a single-center retrospective cohort study and telephone survey of female patients ages 18-49 at the time of kidney, pancreas, or liver transplant from 2000 to 2012 (n = 532). Data on pregnancy counseling, fertility, and maternal, fetal- and transplant-specific outcomes were collected. Multivariate Cox models assessed the impact of pregnancy on graft-specific outcomes. RESULTS: The survey response rate was 29% (n = 152). One-third (n = 51) of women were actively counseled against pregnancy by one or more providers. A total of 17 pregnancies occurred among nine patients (5.9%), with 47% live births, 47% early embryonic demises, 5.9% stillbirths. Of live births, 50% were premature. Gestational complications, including diabetes, hypertension, and preeclampsia were present in 88% of mothers. Pregnancy after transplant was associated with higher rates of acute rejection than nulliparous transplant recipients (33% vs. 5.6%, p = 0.07) but did not significantly affect graft survival (HR = 1.00, 95% CI 0.99-1.01), after stratifying by organ and adjusting for clinical factors. CONCLUSION: This study suggests that transplant patients are being counseled against pregnancy despite acceptable risks of complications and no specific effects on long-term graft function.

Predictors of operative failure in parathyroidectomy for primary hyperparathyroidism.

INTRODUCTION: Many adjuncts guide surgical decision making in parathyroidectomy, yet their independent associations with outcome are poorly characterized. We examined a broad range of perioperative factors and used multivariate techniques to identify independent predictors of operative failure (persistent disease) after parathyroidectomy. METHODS: This was a retrospective review of 2239 patients with primary hyperparathyroidism who underwent parathyroidectomy at a single-center from 1999 to 2014. We used multivariate logistic regress to measure associations between multiple perioperative factors and an operative failure (persistent hypercalcemia). RESULTS: Operative failure was identified in 67 patients (3.0%). The following variables were independently associated with operative failure on multivariate analysis: IOPTH criteria met (protective, OR = 0.22, P < 0.001), preoperative calcium (risk factor, OR = 2.27 per unit increase, P < 0.001), weight of excised gland(s) (protective, OR = 0.70 per two-fold increase, P = 0.003), and preoperative PTH (protective, OR = 0.55 per two-fold increase, P = 0.008). CONCLUSION: In addition to the well-established IOPTH criteria, we suggest that consideration of the above independent perioperative risk factors may further inform surgical decision-making in parathyroidectomy.
