Synoptic Versus Narrative Reporting of Prostate Biopsies at a Tertiary Healthcare Institution: Challenges, successes and expectations

Cancer pathology reports are expected to contain all information required for patient management and disease surveillance. Moreover, reports for patients with prostate cancer have become increasingly complex with the addition of more pathological details. This study aimed to compare narrative and synoptic prostate cancer reports for core needle biopsies received at a tertiary hospital in Nigeria in order to determine which form was most complete according to international standards. This study was conducted from January 2010 to December 2015 at the Lagos University Teaching Hospital, Lagos, Nigeria. All malignant prostate cancer histopathology reports received during this period were analysed for the presence of important clinicopathological parameters, including the numbers of cores taken and those involved by the tumour, percentage of tumour involvement, Gleason score and the presence of high-grade prostatic intraepithelial neoplasms (HGPINs) and perineural and lymphovascular invasion. A total of 83 reports were reviewed, of which 27 were in narrative and 56 in synoptic format. The documentation of clinicopathological characteristics in narrative reports was significantly incomplete compared to synoptic reports in recording the number of cores (33.3% versus 96.4%), number of cores involved by the tumour (11.1% versus 94.6%), percentage of cores involved by the tumour (3.7% versus 100.0%) and the presence of HGPINs (7.4% versus 100.0%) and perineural (59.3% versus 98.2%) and lymphovascular (48.1% versus 100.0%) invasion (P <0.001 each). Synoptic reports of malignant prostate cancer biopsies received at the Lagos University Teaching Hospital were found to contain more complete information than narrative reports.

Synoptic operative reporting: assessing the completeness, accuracy, reliability, and efficiency of synoptic reporting for Roux-en-Y gastric bypass.

Synoptic reporting (SR) is one solution to improve the quality of operative reports. However, SR has not been investigated in bariatric surgery despite an identified need by bariatric surgeons. SR for RYGB was developed using quality indicators (QIs) established by a national Delphi process. The objective of this study is to assess the completeness, accuracy, reliability, and efficiency of synoptic versus narrative operative reports (NR) in Roux-en-Y gastric bypass (RYGB). A NR and SR were completed on 104 consecutive RYGBs. Two evaluators independently compared the reports to QIs. Completeness and accuracy measures were determined. Reliability was calculated using Bland-Altman plots and 95% limits of agreement (LOA). Time to complete SR and NR was also compared. The mean completion rate of SR was 99.8% (±SD 0.98%) compared to 64.0% (±SD 6.15%) for NR (t=57.9, p<0.001). All subsections of SR were >99% complete. This was significantly higher than for NR (p<0.001) except for small bowel division details (p=0.530). Accuracy was significantly higher for SR than NR (94.2%±SD 4.31% vs. 53.6%±SD 9.82%, respectively, p<0.001). Rater agreement was excellent for both SR (0.11, 95% LOA -0.53 to 0.75) and NR (-0.26, 95% LOA -4.85 to 4.33) (p=0.242), where 0 denotes perfect agreement. SR completion times were significantly shorter than NR (3:55min±SD 1:26min and 4:50min±SD 0:50min, respectively, p=0.007). The RYGB SR is superior to NR for completeness and accuracy. This platform is also both reliable and efficient. This SR should be incorporated into clinical practice.

A computable pathology report for precision medicine: extending an observables ontology unifying SNOMED CT and LOINC.

BackgroundThe College of American Pathologists (CAP) introduced the first cancer synoptic reporting protocols in 1998. However, the objective of a fully computable and machine-readable cancer synoptic report remains elusive due to insufficient definitional content in Systematized Nomenclature of Medicine – Clinical Terms (SNOMED CT) and Logical Observation Identifiers Names and Codes (LOINC). To address this terminology gap, investigators at the University of Nebraska Medical Center (UNMC) are developing, authoring, and testing a SNOMED CT observable ontology to represent the data elements identified by the synoptic worksheets of CAP.MethodsInvestigators along with collaborators from the US National Library of Medicine, CAP, the International Health Terminology Standards Development Organization, and the UK Health and Social Care Information Centre analyzed and assessed required data elements for colorectal cancer and invasive breast cancer synoptic reporting. SNOMED CT concept expressions were developed at UNMC in the Nebraska Lexicon© SNOMED CT namespace. LOINC codes for each SNOMED CT expression were issued by the Regenstrief Institute. SNOMED CT concepts represented observation answer value sets.ResultsUNMC investigators created a total of 194 SNOMED CT observable entity concept definitions to represent required data elements for CAP colorectal and breast cancer synoptic worksheets, including biomarkers. Concepts were bound to colorectal and invasive breast cancer reports in the UNMC pathology system and successfully used to populate a UNMC biobank.DiscussionThe absence of a robust observables ontology represents a barrier to data capture and reuse in clinical areas founded upon observational information. Terminology developed in this project establishes the model to characterize pathology data for information exchange, public health, and research analytics.

Clinical Safety of Renaming Encapsulated Follicular Variant of Papillary Thyroid Carcinoma: Is NIFTP Truly Benign?

Renaming encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC) to noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was recently suggested to prevent the overtreatment, cost and stigma associated with this low-risk entity. The purpose of this study is to document the incidence and further assess the clinical outcomes of reclassifying EFVPTC to NIFTP. We searched synoptic pathologic reports from a high-volume academic endocrine surgery hospital from 2004 to 2013. The standard of surgical pathology practice was based on complete submission of malignant thyroid nodules along with the nontumorous thyroid parenchyma. Rigid morphological criteria were used for the diagnosis of noninvasive EFVPTC, currently known as NIFTP. A retrospective chart review was conducted looking for evidence of malignant behavior. One hundred and two patients met the strict inclusion criteria of NIFTP. The incidence of NIFTP in our cohort was 2.1% of papillary thyroid cancer cases during the studied time period. Mean follow-up was 5.7years (range 0-11). Five patients were identified with nodal metastasis and one patient with distant metastasis. Overall, six patients showed evidence of malignant behavior representing 6% of patients with NIFTP. Our study demonstrates that the incidence of NIFTP is significantly lower than previously thought. Furthermore, evidence of malignant behavior was seen in a significant number of NIFTP patients. Although the authors fully support the de-escalation of aggressive treatment for low-risk thyroid cancers, NIFTP behaves as a low-risk thyroid cancer rather than a benign entity and ongoing surveillance is warranted.

Electronic synoptic reporting: assessing the completeness of synoptic and narrative reports for Roux-en-Y gastric bypass

BackgroundOperative reporting is the foundation of surgical communication. The quality indicators (QIs) contained in these reports can be used to document the performance of processes that affect patient care and may afford quality assurance with improvement in healthcare. ObjectivesWe assessed the degree to which the electronic synoptic report (SR) documents the operative QIs compared with narrative reports (NR) for Roux-en-Y gastric bypass (RYGB). The time to report availability on patient chart was also identified as a secondary measure. SettingAcademic center, public hospital, Canada. MethodsA total of 40 prospectively collected RYGB synoptic reports and 40 case-matched historical NRs were compared against checklist QIs that were established by a national Delphi process. These checklist QIs are validated and have high interrater agreement at our institution. Time from dictation to report availability on patient chart was measured. ResultsSR had a mean completion of 99.7% (±standard deviation [SD] 1.3%) compared with 64.0% (±SD 6.3%) for NR (t = 36.0, P<.0001). All subsections of SR were>99% complete and significantly higher than NR (P<.001). The mean time from NR dictation to report availability was 4.14 days (SD±3.17, range 0–10 d). All SRs were in the operative area after the procedure and were available immediately. ConclusionThe RYGB synoptic report is superior to the narrative report for inclusion of accepted quality indicators and time to availability. Important elements, including process of care, demographic characteristics, and anatomic-related data, were often missing from the NR. SR is a promising method for improving documentation for RYGB.

Evaluating the Hydrological Cycle over Land Using the Newly-Corrected Precipitation Climatology from the Global Precipitation Climatology Centre (GPCC)

The 2015 release of the precipitation climatology from the Global Precipitation Climatology Centre (GPCC) for 1951–2000, based on climatological normals of about 75,100 rain gauges, allows for quantification of mean land surface precipitation as part of the global water cycle. In GPCC’s 2011-release, a bulk climatological correction was applied to compensate for gauge undercatch. In this paper we derive an improved correction approach based on the synoptic weather reports for the period 1982–2015. The compared results show that the climatological approach tends to overestimate the correction for Central and Eastern Europe, especially in the northern winter, and in other regions throughout the year. Applying the mean weather-dependent correction to the GPCC’s uncorrected precipitation climatology for 1951–2000 gives a value of 854.7 mm of precipitation per year (excluding Antarctica) or 790 mm for the global land surface. The warming of nearly 1 K relative to pre-industrial temperatures is expected to be accompanied by a 2%–3% increase in global (land and ocean) precipitation. However, a comparison of climatology for 30-year reference periods from 1931–1960 up to 1981–2010 reveals no significant trend for land surface precipitation. This may be caused by the large variability of precipitation, the varying data coverage over time and other issues related to the sampling of rain-gauge networks. The GPCC continues to enlarge and further improve the quality of its database, and will generate precipitation analyses with homogeneous data coverage over time. Another way to reduce the sampling issues is the combination of rain gauge-based analyses with remote sensing (i.e., satellite or radar) datasets.

Performance of a Web-based Method for Generating Synoptic Reports

Context: The College of American Pathologists (CAP) requires synoptic reporting of all tumor excisions. Objective: To compare the performance of different methods of generating synoptic reports. Methods: Completeness, amendment rates, rate of timely ordering of ancillary studies (KRAS in T4/N1 colon carcinoma), and structured data file extraction were compared for four different synoptic report generating methods. Results: Use of the printed tumor protocols directly from the CAP website had the lowest completeness (84%) and highest amendment (1.8%) rates. Reformatting these protocols was associated with higher completeness (94%, P < 0.001) and reduced amendment (1%, P = 0.20) rates. Extraction into a structured data file was successful 93% of the time. Word-based macros improved completeness (98% vs. 94%, P < 0.001) but not amendment rates (1.5%). KRAS was ordered before sign out 89% of the time. In contrast, a web-based product with a reminder flag when items were missing, an embedded flag for data extraction, and a reminder to order KRAS when appropriate resulted in improved completeness (100%, P = 0.005), amendment rates (0.3%, P = 0.03), KRAS ordering before sign out (100%, P = 0.23), and structured data extraction (100%, P < 0.001) without reducing the speed (P = 0.34) or accuracy (P = 1.00) of data extraction by the reader. Conclusion: Completeness, amendment rates, ancillary test ordering rates, and data extraction rates vary significantly with the method used to construct the synoptic report. A web-based method compares favorably with all other methods examined and does not reduce reader usability.

Roadmap to a Comprehensive Clinical Data Warehouse for Precision Medicine Applications in Oncology.

Leading institutions throughout the country have established Precision Medicine programs to support personalized treatment of patients. A cornerstone for these programs is the establishment of enterprise-wide Clinical Data Warehouses. Working shoulder-to-shoulder, a team of physicians, systems biologists, engineers, and scientists at Rutgers Cancer Institute of New Jersey have designed, developed, and implemented the Warehouse with information originating from data sources, including Electronic Medical Records, Clinical Trial Management Systems, Tumor Registries, Biospecimen Repositories, Radiology and Pathology archives, and Next Generation Sequencing services. Innovative solutions were implemented to detect and extract unstructured clinical information that was embedded in paper/text documents, including synoptic pathology reports. Supporting important precision medicine use cases, the growing Warehouse enables physicians to systematically mine and review the molecular, genomic, image-based, and correlated clinical information of patient tumors individually or as part of large cohorts to identify changes and patterns that may influence treatment decisions and potential outcomes.

Intraepithelial lymphocytes, scores, mimickers and challenges in diagnosing gluten-sensitive enteropathy (celiac disease).

The upper digestive tract is routinely scoped for several causes of malabsorption, and the number of duodenal biopsy specimens has increased notably in the last 10 years. Gluten-sensitive enteropathy (GSE) is an autoimmune disease, which shows an increasing prevalence worldwide and requires a joint clinico-pathological approach. The classical histopathology of GSE with partial or total villous blunting is well recognized, but the classification of GSE is not straightforward. Moreover, several mimickers of GSE with intraepithelial lymphocytosis have been identified in the last 20 years, with drug interactions and medical comorbidities adding to the conundrum. In this review, we report on the normal duodenal mucosa, the clinical presentation and laboratory diagnosis of GSE, the duodenal intraepithelial lymphocytes and immunophenotype of GSE-associated lymphocytes, the GSE mimickers, the differences “across oceans” among guidelines in diagnosing GSE, and the use of a synoptic report for reporting duodenal biopsies in both children and adults in the 21st century.

Synoptic Operative Reporting: Assessing the Reliability, Accuracy, and Completeness of Synoptic Reports for Roux-en-Y Gastric Bypass

Development of consensus-derived quality indicators for laparoscopic Roux-en-Y gastric bypass surgery

BackgroundSynoptic operative reporting is a solution to the poor quality of narrative reports. ObjectiveTo develop operative report quality indicators (QI) for laparoscopic Roux-en-Y gastric bypass (LRYGB) to generate validated parameters by which these reports can be evaluated and improved. SettingUniversity hospital in Canada. MethodsA Delphi protocol was used to determine QIs for LRYGB reporting. Bariatric surgeons across Canada were recruited along with key physician stakeholders to participate via a secure web-based platform. Participants initially submitted potential QIs. These were grouped by theme. Items were rated on 9-point Likert scales in subsequent rounds. Scores of 70% or greater were used for inclusion consensus, and 30% or less denoted exclusion. Elements scoring 30% to 70% were recirculated by runoff in subsequent rounds to generate the final list of QIs. ResultsFour community and 4 academic bariatric surgeons were invited, representing all provinces performing LRYGB. The 4 multidisciplinary invitees included 1 minimally invasive/acute care surgeon, 1 tertiary abdominal radiologist, 1 gastroenterologist performing advanced endoscopy, and 1 general surgeon with expertise in synoptic reporting. Round 1 achieved an 83.3% (10/12) response and identified 91 potential items for consideration. Round 2 had a 100% response, and 69 items reached inclusion consensus. The third round achieved a 100% response and resulted in 75 QIs reaching final inclusion consensus. ConclusionThis study established consensus-derived multidisciplinary QIs for LRYGB operative reports. This will allow further assessment of the quality of narrative reports and afford the development of a synoptic operative report that may ameliorate identified deficiencies.

Key gaps in pathologic reporting for appendiceal mucinous neoplasms: time for universal synoptic reporting?

The prognosis of appendiceal mucinous neoplasms (AMN) is directly related to their histopathology. Existing classification schemes encompass tumors with widely divergent clinical behaviors within a single diagnosis, making it difficult for clinicians to interpret pathology reports to counsel patients on optimal management. We sought to examine pathology reports generated for AMN for inclusion of essential histologic features. Pathology reports of appendectomy specimens with a diagnosis of AMN (2002-2015) at our center ("internal") and from referring institutions ("external") were retrospectively reviewed for inclusion of the following 5 essential items: layer of invasion, mucin dissection (low grade neoplasms only), perforation, margins, and serosal implants. Sixty-nine patients were included, 54 with external reports available. Benign/low grade tumors comprised 29.0% and 27.8% of internal and external reports, respectively. Thirty-seven internal reports (53.6%) were signed out by specialist gastrointestinal pathologists. External reports were 66.7% complete for layer of invasion, 26.7% for mucin dissection, 64.8% for perforation, 68.5% for margins, 53.7% for serosal implants, and 18.5% for all items. Internal reports were 75.4% complete for layer of invasion, 40.0% for mucin dissection, 40.6% for perforation, 82.6% for margins, 69.6% for serosal implants, and 17.4% for all items. Eight external (14.8%) and 24 internal (34.8%) reports were synoptic. Synoptic reports were more likely to be complete for all key items both external and internal. Most pathology reports are incomplete for essential features needed for management and discussion of AMN with patients. Synoptic reports improve completeness of reporting for these tumors.

A5054 - Documentation of Quality of Care Data for Roux en Y Gastric Bypass: Comparison of Synoptic and Narrative Operative Reports

Synoptic operative reports for spinal cord injury patients as a tool for data quality.

The advent of synoptic operative reports has revolutionized how clinical data are captured at the time of care. In this article, an electronic synoptic operative report for spinal cord injury was implemented using interoperable standards, HL7 and Systematized Nomenclature of Medicine-Clinical Terms. Subjects (N = 10) recruited for a pilot study completed recruitment and feedback questionnaires, and produced both an electronic synoptic operative report for spinal cord injury report and a dictated narrative operative report for an actual patient case. Results indicated heterogeneity by subjects in access and use of electronic sources of patient data. Feedback questionnaire results confirmed that subjects were comfortable using both methods for data entry of operative reports, and that some were unable to find the diagnosis terms they needed in electronic synoptic operative report for spinal cord injury. Data quality improved. Electronic synoptic operative report for spinal cord injury reports were more complete (95.26%) than dictated (80%) for all subjects. An accuracy assessment, which considered usability for secondary data use, was conducted and the electronic synoptic operative report for spinal cord injury was demonstrated to improve accuracy.

The effects of implementing synoptic pathology reporting in cancer diagnosis: a systematic review.

Pathology reporting is evolving from a traditional narrative report to a more structured synoptic report. Narrative reporting can cause misinterpretation due to lack of information and structure. In this systematic review, we evaluate the impact of synoptic reporting on completeness of pathology reports and quality of pathology evaluation for solid tumours. Pubmed, Embase and Cochrane databases were systematically searched to identify studies describing the effect of synoptic reporting implementation on completeness of reporting and quality of pathology evaluation of solid malignant tumours. Thirty-three studies met the inclusion criteria. All studies, except one, reported an increased overall completeness of pathology reports after introduction of synoptic reporting (SR). Most frequently studied cancers were breast (n = 9) and colorectal cancer (n = 16). For breast cancer, narrative reports adequately described ‘tumour type’ and ‘nodal status’. Synoptic reporting resulted in improved description of ‘resection margins’, ‘DCIS size’, ‘location’ and ‘presence of calcifications’. For colorectal cancer, narrative reports adequately reported ‘tumour type’, ‘invasion depth’, ‘lymph node counts’ and ‘nodal status’. Synoptic reporting resulted in increased reporting of ‘circumferential margin’, ‘resection margin’, ‘perineural invasion’ and ‘lymphovascular invasion’. In addition, increased numbers of reported lymph nodes were found in synoptic reports. Narrative reports of other cancer types described the traditional parameters adequately, whereas for ‘resection margins’ and ‘(lympho)vascular/perineural invasion’, implementation of synoptic reporting was necessary. Synoptic reporting results in improved reporting of clinical relevant data. Demonstration of clinical impact of this improved method of pathology reporting is required for successful introduction and implementation in daily pathology practice.Electronic supplementary materialThe online version of this article (doi:10.1007/s00428-016-1935-8) contains supplementary material, which is available to authorized users.

Functional Assessment of Synoptic Pathology Reporting for Ovarian Cancer

Background: Ovarian cancer has one of the highest death/incidence rates and is commonly diagnosed at an advanced stage. In the recent WHO classification, new histotypes were classified which respond differently to chemotherapy. The e-standardized synoptic cancer pathology reports offer the clinicians essential and reliable information. The aim of our project was to develop an e-template for the standardized synoptic pathology reporting of ovarian carcinoma [based on the checklist of the College of American Pathologists (CAP) and the recent WHO/FIGO classification] to introduce a uniform and improved quality of cancer pathology reports. A functional and qualitative evaluation of the synoptic reporting was performed. Methods: An indispensable module for e-synoptic reporting was developed and integrated into the Hospital Information System (HIS). The electronic pathology system used a standardized structure with drop-down lists of defined elements to ensure completeness and consistency of reporting practices with the required guidelines. All ovarian cancer pathology reports (partial and final) with the corresponding glass slides selected from a 1-year current workflow were revised for the standard structured reports, and 42 tumors [13 borderline tumors and 29 carcinomas (mainly serous)] were included in the study. Results: Analysis of the reports for completeness against the CAP checklist standard showed a lack of pTNM staging in 80% of the partial or final unstructured reports; ICD-O coding was missing in 83%. Much less frequently missed or unstated data were: ovarian capsule infiltration, angioinvasion and implant evaluation. The e-records of ovarian tumors were supplemented with digital macro- and micro-images and whole-slide images. Conclusions: The e-module developed for synoptic ovarian cancer pathology reporting was easily incorporated into HIS.CGM CliniNet and facilitated comprehensive reporting; it also provided open access to the database for concerned recipients. The e-synoptic pathology reports appeared more accurate, clear and conclusive than traditional narrative reports. Standardizing structured reporting and electronic tools allows open access and downstream utilization of pathology data for clinicians and tumor registries.

Structured reporting ensures complete content and quick detection of essential data in pathology reports of oncological breast resection specimens.

There is increasing evidence that not only the way of data acquisition but also the design of data visualization (i.e., the format) has impact on the quality of pathology reports. Therefore, we investigated the correlation between the format of pathology reports and the amount as well as the detection time of transmitted data. All reports of oncological breast resection specimens referred to the Institute for Surgical Pathology, University Medical Center Freiburg, between 2003 and 2011 (n = 4181) were classified into descriptive reports (DR, n = 856), structured reports (SR, n = 2455), or template-based synoptic reports (TBSR, n = 870). The reports were screened regarding the content of nine organ-specific essential data. The amount of recorded essential data per report was summarized in an essential data score (EDS) and the format types were statistically compared regarding their EDS. Additionally, we measured the time a gynecologist needed to detect all nine essential data within a subset of reports and compared the format types regarding the detection times statistically. A full-score EDS of 9 was seen in 28.4 % of all reports, in 4 % of DRs, in 21.4 % of SRs, and in 72.3 % of TBSRs (p < 0.0001). Median EDS of DRs was 7, of SRs 8, and of TBSRs 9 (p < 0.0001). Data regarding tumor localization, tumor size, specific grading, angioinvasion, hormone receptor status, and additional findings were mentioned more frequently in TBSRs compared to other format type reports with a statistically highly significant difference (p < 0.0001). Mean data detection time decreased significantly from 26 to 20 and 14 s in DRs, SRs, and TBSRs, respectively. Our results clearly show that due to the use of TBSRs reporting of oncological breast resection specimens are improved regarding the content of essential data and the clarity of the data layout resulting in a rapid detection of essential data by clinicians.

Electronic operative reports to support quality improvement and patient-centered care.

95 Background: Operative reports (OP) for cancer surgery are usually narrated, although they provide inconsistent and incomplete information for patient care. National standards for cancer OP were unavailable until 2007. Over 10 years, surgeons in four Canadian provinces have transitioned from narrative to electronic synoptic reporting (ESP) for specific cancers. The electronic OP are now considered a patient medical record and integral to subsequent patient care. Surgeons are using electronic reports for quality assurance, billing, medical-legal conflict resolution and research. Methods: Disease-site expert panels were formed to bring together surgeons to discuss, identify, develop and form consensus on a core set of elements for breast, colorectal, ovary, endometrial, lung, prostate, and thyroid cancer surgeries and 64 quality indicators to set practice standards to consistently and comprehensively record pre-operative, operative procedures, intra-operative observations and pathology, clinical stage findings, complications and outcomes. These standards were implemented using ESP in four provinces and a mixed methods evaluation was carried out. Results: 245 surgeons in academic and community hospitals piloted and implemented pan-Canadian standards and generated 2000 synoptic reports and 729 discharge summaries over six months. In comparison to narrative reports, surgeons reported that the electronic synoptic reports: Capture complete and essential content (89% - 96%), 50% more; Contain 25 – 50 items vs. 2000 narrated words; Faster completion and turnaround time (5- 15 minutes) vs. 5 days; Rapid transmission to patient charts (91% in 1 hour and 97% within 24 hours) vs. 30 – 90 days; Result in cost savings $90/case; Enable performance measurement of surgical care to assess quality and outcome of surgery (e.g., residual disease and survival in patients) and length of aggressive vs. non-aggressive surgery and hospital stay (5.49 hours and 8.39 days vs. 3.06 hours and 6.83 days). Conclusions: Surgeons are building partnerships with key players to strategize best approaches to enable a system-wide adoption and implementation of synoptic operative reporting and quality of care measurement across Canada.

Pathology report data extraction from relational database using R, with extraction from reports on melanoma of skin as an example

Background: Different methods have been described for data extraction from pathology reports with varying degrees of success. Here a technique for directly extracting data from relational database is described. Methods: Our department uses synoptic reports modified from College of American Pathologists (CAP) Cancer Protocol Templates to report most of our cancer diagnoses. Choosing the melanoma of skin synoptic report as an example, R scripting language extended with RODBC package was used to query the pathology information system database. Reports containing melanoma of skin synoptic report in the past 4 and a half years were retrieved and individual data elements were extracted. Using the retrieved list of the cases, the database was queried a second time to retrieve/extract the lymph node staging information in the subsequent reports from the same patients. Results: 426 synoptic reports corresponding to unique lesions of melanoma of skin were retrieved, and data elements of interest were extracted into an R data frame. The distribution of Breslow depth of melanomas grouped by year is used as an example of intra-report data extraction and analysis. When the new pN staging information was present in the subsequent reports, 82% (77/94) was precisely retrieved (pN0, pNI, pN2 and pN3). Additional 15% (14/94) was retrieved with certain ambiguity (positive or knowing there was an update). The specificity was 100% for both. The relationship between Breslow depth and lymph node status was graphed as an example of lesion-specific multi-report data extraction and analysis. Conclusions: R extended with RODBC package is a simple and versatile approach well-suited for the above tasks. The success or failure of the retrieval and extraction depended largely on whether the reports were formatted and whether the contents of the elements were consistently phrased. This approach can be easily modified and adopted for other pathology information systems that use relational database for data management.

Reporting Gleason grade/score in synoptic reports of radical prostatectomies

Context: The format of a synoptic report can significantly affect the accuracy, speed, and preference with which a reader can retrieve information. Objective: The objective of this study is to compare different formats of Gleason grading/score in synoptic reports of radical prostatectomies. Methods: The performance of 16 nonpathologists (cancer registrars, MDs, medical non-MDs, and nonmedical) at identifying specific information in various formatted synoptic reports using a computerized quiz that measured both accuracy and speed. Results: Compared to the standard format (primary, secondary, tertiary grades, and total score on separate lines), omitting tertiary grade when “Not applicable” reduced accuracy (72 vs. 97%, P < 0.001) and increased time to retrieve information 63% (P < 0.001). No user preferred to have tertiary grade omitted. Both the biopsy format (primary + secondary = total score, tertiary on a separate line) and the single line format (primary + secondary + (tertiary) -> total score) were associated with increased speed of data extraction (18 and 24%, respectively, P < 0.001). The single line format was more accurate (100% vs. 97%, P = 0.02). No user preferred the biopsy format, and only 7/16 users preferred the single line format. Conclusions: Different report formats for Gleason grading significantly affect users speed, accuracy, and preference; users do not always prefer either speed or accuracy.
