RESUMEN
BACKGROUND: Patients undergoing sleeve gastrectomy (SG) experience transformative changes in eating-related experiences that include eating-related symptoms, emotions, and habits. Long-term assessment of these endpoints with rigorous patient-reported outcome measures (PROMs) is limited. We assessed patients undergoing SG with the Body-Q Eating Module PROMs. METHODS: All patients evaluated at the Emory Bariatric Center were given the Body-Q Eating Modules questionnaire at preoperative/postoperative clinic visits. Rasch scores and prevalence of relevant endpoints were assessed across six time-points of interest: preoperatively, post-operative months 0-6, 7-12, 12-24, 24-36, and over 36. Student's t-test and Chi-square test were used for analysis. RESULTS: Overall, 1,352 questionnaires were completed pre-operatively and 493 postoperatively. Survey compliance was 81%. Compared to the pre-operative group, the post-operative group had lower BMI (39.7 vs. 46.4, p < 0.001) and higher age (46.3 vs. 44.9, p = 0.019). Beginning one year after SG, patients experience more frequent eating-related pain, nausea and constipation compared to pre-operative baseline (p < 0.05). They also more frequently experience eating-related regurgitation and dumping syndrome-related symptoms beginning post-operative year two (p < 0.05). In the first year after SG, patients more rarely feel eating-related embarrassment, guilt, and disappointment compared to pre-operative baseline (p < 0.05). These improvements disappear one year after SG, after which patients more frequently experience feeling out of control, unhappy, like a failure, disappointed, and guilty (p < 0.05). In the first year after SG, patients experience an increased frequency in positive eating behaviors (ate healthy foods, showed self-control, stopped before full; (p < 0.05). Only two eating-related behavior improvements persist long-term: feeling in control and eating the right amount (p < 0.05). CONCLUSIONS: Patients undergoing SG may experience more frequent eating-related symptoms, distress, and behavior in the long-term. These findings can enhance the pre-operative informed consent and guide development of a more tailored approach to postoperative clinical management such as more frequent visits with the dietician.

INTRODUCTION: Assessment of surgical resident technical performance is an integral component of any surgical training program. Timely assessment delivered in a structured format is a critical step to enhance technical skills, but residents often report that the quality and quantity of timely feedback received is lacking. Moreover, the absence of written feedback with specificity can allow residents to seemingly progress in their operative milestones as a junior resident, but struggle as they progress into their postgraduate year 3 and above. We therefore designed and implemented a web-based intraoperative assessment tool and corresponding summary "dashboard" to facilitate real-time assessment and documentation of technical performance. MATERIALS AND METHODS: A web form was designed leveraging a cloud computing platform and implementing a modified Ottawa Surgical Competency Operating Room Evaluation instrument; this included additional, procedure-specific criteria for select operations. A link to this was provided to residents via email and to all surgical faculty as a Quick Response code. Residents open and complete a portion of the form on a smartphone, then relinquish the device to an attending surgeon who then completes and submits the assessment. The data are then transferred to a secure web-based reporting interface; each resident (together with a faculty advisor) can then access and review all completed assessments. RESULTS: The Assessment form was activated in June 2021 and formally introduced to all residents in July 2021, with residents required to complete at least one assessment per month. Residents with less predictable access to operative procedures (night float or Intensive Care Unit) were exempted from the requirement on those months. To date a total of 559 assessments have been completed for operations performed by 56 trainees, supervised by 122 surgical faculty and senior trainees. The mean number of procedures assessed per resident was 10.0 and the mean number per assessor was 4.6. Resident initiation of Intraoperative Assessments has increased since the tool was introduced and scores for technical and nontechnical performance reliably differentiate residents by seniority. CONCLUSIONS: This novel system demonstrates that an online, resident-initiated technical assessment tool is feasible to implement and scale. This model's requirement that the attending enter performance ratings into the trainee's electronic device ensures that feedback is delivered directly to the trainee. Whether this aspect of our assessment ensures more direct and specific (and therefore potentially actionable) feedback is a focus for future study. Our use of commercial cloud computing services should permit cost-effective adoption of similar systems at other training programs.

BACKGROUND: Enhanced recovery protocols (ERPs) after metabolic and bariatric surgery (MBS) may help decrease length of stay (LOS) and postoperative nausea/vomiting but implementation is often fraught with challenges. The primary aim of this pilot study was to standardize a MBS ERP with a real-time data support dashboard and checklist and assess impact on global and individual element compliance. The secondary aim was to evaluate 30 day outcomes including LOS, hospital readmissions, and re-operations. METHODS AND PROCEDURES: An ERP, paper checklist, and virtual dashboard aligned on MBS patient care elements for pre-, intra-, and post-operative phases of care were developed and sequentially deployed. The dashboard includes surgical volumes, operative times, ERP compliance, and 30 day outcomes over a rolling 18 month period. Overall and individual element ERP compliance and outcomes were compared pre- and post-implementation via two-tailed Student's t-tests. RESULTS: Overall, 471 patients were identified (pre-implementation: 193; post-implementation: 278). Baseline monthly average compliance rates for all patient care elements were 1.7%, 3.7%, and 6.2% for pre-, intra-, and post-operative phases, respectively. Following ERP integration with dashboard and checklist, the intra-operative phase achieved the highest overall monthly average compliance at 31.3% (P < 0.01). Following the intervention, pre-operative acetaminophen administration had the highest monthly mean compliance at ≥ 99.1%. Overall TAP block use increased 3.2-fold from a baseline mean rate of 25.4-80.8% post-implementation (P < 0.01). A significant decrease in average intra-operative monthly morphine milligram equivalents use was noted with a 56% drop pre- vs. post-implementation. Average LOS decreased from 2.0 to 1.7 days post-implementation with no impact on post-operative outcomes. CONCLUSION: Implementation of a checklist and dashboard facilitated ERP integration and adoption of process measures with many improvements in compliance but no impact on 30 day outcomes. Further research is required to understand how clinical support tools can impact ERP adoption among MBS patients.

BACKGROUND: Multiple medication changes are common after bariatric surgery, but pharmacist assistance in this setting is not well described. This study evaluated the feasibility and effectiveness of a pharmacy-led initiative for facilitating discharge medicine reconciliation after bariatric surgery. METHODS: A standardized post-operative pharmacy consult evaluation was conducted on bariatric surgery inpatients at a single academic center starting 1/2/2019. Retrospective chart review evaluated patient characteristics, medication changes, and 30-day outcomes pre-intervention (7/2018-12/2018) and post-intervention (1/2019-12/2019). Two-sample t tests or binomial tests were used for continuous or categorical variables, respectively; a p-value of < 0.05 was deemed statistically significant. RESULTS: A total of 353 patients were identified for study inclusion (n = 158 pre-intervention, n = 195 post-intervention) with a mean age of 45 years, 87% female, and 71% sleeve gastrectomy. Overall pharmacy consultation compliance was 94% with 77.0% of home medication recommendations followed. Non-narcotic pain medication prescription use significantly increased (39% pre- vs. 54% post-intervention; p < 0.001). At discharge, the average number of changed or new medications significantly increased (3.7 ± 1.2 pre- vs. 4.2 ± 1.8 post-intervention; p = 0.003) while the average number of stopped medications was similar (1.2 ± 1.5 pre- vs. 1.5 ± 1.9 post-intervention; p = 0.09). Anti-hypertensive medications were decreased or stopped substantially more often with pharmacist input (44.7% pre- vs. 85.4% post-intervention; p < 0.001). Three medication-related readmissions happened pre-intervention with none post-intervention. Outpatient medication-related phone calls did considerably increase (31% pre- vs. 39% post-intervention; p = 0.04), while overall 30-day readmissions significantly decreased (7.6% pre- vs. 1.5% post-intervention; p = 0.04). CONCLUSIONS: Inpatient pharmacy consultation facilitated rapid alteration to more appropriate therapy for hypertension management and significantly increased use of non-narcotic pain medications upon discharge among bariatric surgery patients. Improved protocol adherence is anticipated with program maturity and patient education interventions will be deployed to address outpatient phone calls.

Environmental factors clearly affect colorectal cancer (CRC) incidence, but the mechanisms through which these factors function are unknown. One prime candidate is an altered colonic microbiota. Here we show that the mucosal microbiota organization is a critical factor associated with a subset of CRC. We identified invasive polymicrobial bacterial biofilms (bacterial aggregates), structures previously associated with nonmalignant intestinal pathology, nearly universally (89%) on right-sided tumors (13 of 15 CRCs, 4 of 4 adenomas) but on only 12% of left-sided tumors (2 of 15 CRCs, 0 of 2 adenomas). Surprisingly, patients with biofilm-positive tumors, whether cancers or adenomas, all had biofilms on their tumor-free mucosa far distant from their tumors. Bacterial biofilms were associated with diminished colonic epithelial cell E-cadherin and enhanced epithelial cell IL-6 and Stat3 activation, as well as increased crypt epithelial cell proliferation in normal colon mucosa. High-throughput sequencing revealed no consistent bacterial genus associated with tumors, regardless of biofilm status. However, principal coordinates analysis revealed that biofilm communities on paired normal mucosa, distant from the tumor itself, cluster with tumor microbiomes as opposed to biofilm-negative normal mucosa bacterial communities also from the tumor host. Colon mucosal biofilm detection may predict increased risk for development of sporadic CRC.

BACKGROUND: Enterotoxigenic Bacteroides fragilis (ETBF) produces the Bacteroides fragilis toxin, which has been associated with acute diarrheal disease, inflammatory bowel disease, and colorectal cancer (CRC). ETBF induces colon carcinogenesis in experimental models. Previous human studies have demonstrated frequent asymptomatic fecal colonization with ETBF, but no study has investigated mucosal colonization that is expected to impact colon carcinogenesis. METHODS: We compared the presence of the bft gene in mucosal samples from colorectal neoplasia patients (cases, n = 49) to a control group undergoing outpatient colonoscopy for CRC screening or diagnostic workup (controls, n = 49). Single bacterial colonies isolated anaerobically from mucosal colon tissue were tested for the bft gene with touch-down polymerase chain reaction. RESULTS: The mucosa of cases was significantly more often bft-positive on left (85.7%) and right (91.7%) tumor and/or paired normal tissues compared with left and right control biopsies (53.1%; P = .033 and 55.5%; P = .04, respectively). Detection of bft was concordant in most paired mucosal samples from individual cases or controls (75% cases; 67% controls). There was a trend toward increased bft positivity in mucosa from late- vs early-stage CRC patients (100% vs 72.7%, respectively; P = .093). In contrast to ETBF diarrheal disease where bft-1 detection dominates, bft-2 was the most frequent toxin isotype identified in both cases and controls, whereas multiple bft isotypes were detected more frequently in cases (P ≤ .02). CONCLUSIONS: The bft gene is associated with colorectal neoplasia, especially in late-stage CRC. Our results suggest that mucosal bft exposure is common and may be a risk factor for developing CRC.

BACKGROUND: Surgical site infections are a potentially preventable patient harm. Emerging evidence suggests that the implementation of evidence-based process measures for infection reduction is highly variable. OBJECTIVE: The purpose of this work was to develop an auditing tool to assess compliance with infection-related process measures and establish a system for identifying and addressing defects in measure implementation. DESIGN: This was a retrospective cohort study using electronic medical records. SETTING: We used the auditing tool to assess compliance with 10 process measures in a sample of colorectal surgery patients with and without postoperative infections at an academic medical center (January 2012 to March 2013). PATIENTS: We investigated 59 patients with surgical site infections and 49 patients without surgical site infections. MAIN OUTCOME MEASURES: First, overall compliance rates for the 10 process measures were compared between patients with infection vs patients without infection to assess if compliance was lower among patients with surgical site infections. Then, because of the burden of data collection, the tool was used exclusively to evaluate quarterly compliance rates among patients with infection. The results were reviewed, and the key factors contributing to noncompliance were identified and addressed. RESULTS: Ninety percent of process measures had lower compliance rates among patients with infection. Detailed review of infection cases identified many defects that improved following the implementation of system-level changes: correct cefotetan redosing (education of anesthesia personnel), temperature at surgical incision >36.0°C (flags used to identify patients for preoperative warming), and the use of preoperative mechanical bowel preparation with oral antibiotics (laxative solutions and antibiotics distributed in clinic before surgery). Quarterly compliance improved for 80% of process measures by the end of the study period. LIMITATIONS: This study was conducted on a small surgical cohort within a select subspecialty. CONCLUSIONS: The infection auditing tool is a useful strategy for identifying defects and guiding quality improvement interventions. This is an iterative process requiring dedicated resources and continuous patient and frontline provider engagement.

Over one billion people worldwide harbor intestinal parasites. Parasitic intestinal infections have a predilection for developing countries due to overcrowding and poor sanitation but are also found in developed nations, such as the United States, particularly in immigrants or in the setting of sporadic outbreaks. Although the majority of people are asymptomatically colonized with parasites, the clinical presentation can range from mild abdominal discomfort or diarrhea to serious complications, such as perforation or bleeding. Protozoa and helminths (worms) are the two major classes of intestinal parasites. Protozoal intestinal infections include cryptosporidiosis, cystoisosporiasis, cyclosporiasis, balantidiasis, giardiasis, amebiasis, and Chagas disease, while helminth infections include ascariasis, trichuriasis, strongyloidiasis, enterobiasis, and schistosomiasis. Intestinal parasites are predominantly small intestine pathogens but the large intestine is also frequently involved. This article highlights important aspects of parasitic infections of the colon including epidemiology, transmission, symptoms, and diagnostic methods as well as appropriate medical and surgical treatment.
RESUMEN
OBJECTIVE: COVID-19 greatly influenced medical education and the residency match. As new guidelines were established to promote safety, travel was restricted, visiting rotations discontinued, and residency interviews turned virtual. The purpose of this study is to assess the geographic trends in distribution of successfully matched General Surgery applicants prior to and after the implementation of pandemic guidelines, and what we can learn from them as we move forward. DESIGN: This was a retrospective review of 129 Accreditation Council for Graduate Medical Education (ACGME) accredited, academic General Surgery Residency Programs across 46 states and the District of Columbia. Categorically matched residents' medical schools (i.e., home institutions), medical school states, and medical school regions as defined per the Association of American Medical Colleges (AAMC), were compared to the same geographic datapoints as their residency program. Preliminary residents were excluded. Residents in the 2018, 2019, and 2020 cycles were sub-categorized into the "pre-COVID" group and residents in the 2021 and 2022 applications cycles were sub-categorized into the "post-COVID" group. The percentages of residents who matched at their home institution, in-state, and in-region were examined. SETTING: Multiple ACGME-accredited, university-affiliated General Surgery Residency Programs across the United States of America. PARTICIPANTS: A total of 4033 categorical General Surgery residents were included. RESULTS: Of 4033 categorical residents who matched between 2018 and 2022, 56.1% (nâ¯=â¯2,263) were in the pre-COVID group and 43.9% (nâ¯=â¯1770) were in the post-COVID group. In the pre-COVID group 14.4% (nâ¯=â¯325) of residents remained in-home (IH), 24.4% (nâ¯=â¯553) in-state (IS), and 37.0% (nâ¯=â¯837) in- region (IR), compared to 18.8% IH (nâ¯=â¯333), 27.8% IS (nâ¯=â¯492), and 39.9% IR (nâ¯=â¯706) in the post-COVID group, respectively. Significant increases for IH and IS resident matching at 4.5% and 3.4%, respectively, were noted in the post-COVID period (p < 0.05). CONCLUSION: The COVID-19 pandemic, and the ensuing changes adopted to promote safety, significantly impacted medical student opportunities and the General Surgery residency application process. General Surgery match data over the last 5 years reveals a statistically significant increase in the percentage of applicants matching at in-home and in-state institutions after the pandemic.

BACKGROUND: Rectourethral fistulas are uncommon. Retrospective studies and case reports have highlighted various approaches for surgical repair. Because clinical presentations and technical expertise vary widely, no single procedure has been universally adopted. OBJECTIVE: We sought to qualitatively analyze studies describing surgical techniques and outcomes in adult acquired rectourethral fistulas to outline universal approaches for evaluation and management. DATA SOURCES: MEDLINE (PubMed, Ovid) and the Cochrane Library were searched by using the terms rectourethral fistulas, recto-urethral fistulas, urethrorectal fistulas, and prostatourethral-rectal fistulas. STUDY SELECTION: All studies were retrospective, in English, and reported at least 4 cases. Any series with >50% congenital cases or <50% adults (19+ years) was excluded. Of the 569 records identified, 26 articles were included. INTERVENTION: The intervention was surgical repair of rectourethral fistula. MAIN OUTCOME MEASURES: The main outcome measures were successful fistula closure, fistula recurrence or persistence, and permanent fecal and/or urinary diversion. RESULTS: Four hundred sixteen patients were identified, including 169 (40%) who had previous pelvic irradiation and/or ablation. Most patients (90%) underwent 1 of 4 categories of repair: transanal (5.9%), transabdominal (12.5%), transsphincteric (15.7%), and transperineal (65.9%). Tissue interposition flaps, predominantly gracilis muscle, were used in 72% of repairs. The fistula was successfully closed in 87.5%. Overall permanent fecal and/or urinary diversion rates were 10.6% and 8.3%. Most high-volume centers (≥25 patients) performed transperineal repairs with tissue flaps in 100% of cases. LIMITATIONS: This review was limited by the heterogeneity of repairs and bias toward preferred surgical approaches in single-center studies. CONCLUSIONS: Regardless of complexity, rectourethral fistulas have an initial closure rate approaching 90% when the transperineal approach is used. Permanent fecal and/or urinary diversion should be a last resort in patients with devastated, nonfunctional fecal and urinary systems.

PURPOSE: To evaluate the impact of an inpatient pharmacy consult on discharge medications following bariatric surgery. METHODS: A pharmacy consult for discharge medication review for bariatric surgery patients was instituted at an academic medical center. The intervention included conducting a medication history, reviewing home medications for updates post-bariatric surgery, creating and documenting a discharge medication plan, and providing patient education. The impact of the intervention was evaluated by comparing medication classes, doses, and formulations prescribed during the intervention relative to a historical control group. RESULTS: The study included 85 patients who received pharmacist intervention and 167 patients who did not receive pharmacist intervention following bariatric surgery. The prescription of an extended-release medication at discharge in the intervention group was reduced by 19.3% (28.7% vs. 9.4%, p = 0.0005). For patients on hypertension medications, 94.0% had their regimen reduced in the intervention group compared with 37.5% of patients in the control group (p < 0.001). Of patients on insulin at baseline, 87.5% of patients in the intervention group had dose reductions at discharge vs. 66.7% of patients in the control group (p = 0.37). No patients in the intervention group were discharged with oral antihyperglycemic medications or non-insulin injectable medications vs. 33.3% (p = 0.12) and 20.0% (p = 0.47), respectively, in the control group. Readmission rates at 30 days were insignificantly lower in the intervention group (3.5% vs. 4.2%, p = 1). CONCLUSIONS: Clinical pharmacist involvement in the discharge medication reconciliation process for bariatric surgery patients reduced prescribing of unadjusted medication classes, doses, and drug formulations.

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of 30-day mortality after metabolic and bariatric surgery (MBS). Multiple predictive tools exist for VTE risk assessment and extended VTE chemoprophylaxis determination. OBJECTIVE: To review existing risk-stratification tools and compare their predictive abilities. SETTING: MBSAQIP database. METHODS: Retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was performed (2015-2019) for primary minimally invasive MBS cases. VTE clinical factors and risk-assessment tools were evaluated: body mass index threshold of 50 kg/m2, Caprini risk-assessment model, and 3 bariatric-specific tools: the Cleveland Clinic VTE risk tool, the Michigan Bariatric Surgery Collaborative tool, and BariClot. MBS patients were deemed high risk based on criteria from each tool and further assessed for sensitivity, specificity, and positive predictive value. RESULTS: Overall, 709,304 patients were identified with a .37% VTE rate. Bariatric-specific tools included multiple predictors: procedure, age, race, gender, operative time, length of stay, heart failure, and dyspnea at rest; operative time was the only variable common to all. The body mass index cutoff and Caprini risk-assessment model had higher sensitivity but lower specificity when compared with the Michigan Bariatric Surgery Collaborative and BariClot tools. While the sensitivity of the tools varied widely and was overall low, the Cleveland Clinic tool had the highest sensitivity. The bariatric-specific tools would have recommended extended prophylaxis for 1.1%-15.6% of patients. CONCLUSIONS: Existing MBS VTE risk-assessment tools differ widely for inclusion variables, high-risk definition, and predictive performance. Further research and registry inclusion of all significant risk factors are needed to determine the optimal risk-stratified approach for predicting VTE events and determining the need for extended prophylaxis.

Introduction: Intraoperative radiation therapy (IORT) is a minimally invasive radiation option for select patients with early stage breast cancer. This prospective, single institution, pilot study summarizes patient-reported quality of life (QoL) outcomes and clinician-reported toxicity following IORT following breast conservation therapy. Methods: Forty-nine patients were enrolled in a prospective study from 2013 until 2015 to assess QoL and toxicity following breast conservation therapy and IORT. Nine patients did not meet criteria for IORT alone on final pathology and required whole breast irradiation afterwards. These patients were evaluated separately. Validated QoL questionnaires were provided to patients at 1-week, 1-month, and subsequent 6-month intervals for 2 years. Radiation-related toxicity symptoms were evaluated by clinicians at the same time intervals. Likert scale responses were converted to continuous variables to depict patient-reported and clinician-reported outcomes. Results: Outcomes were analyzed as weighted averages of the Likert scale for each symptom. Responses for negative QoL symptoms ranged largely from 0 (none) to 2 (moderate). Responses for positive QoL symptoms ranged largely from 3 (quite a bit) to 4 (very much). Seventy-five percent of patients developed a toxicity; however, 99% of the toxicities were grades 1 and 2. All toxicities demonstrated a downward trend over time, with the exception of breast fibrosis and nodularity, which increased over time. There were no local recurrences upon 2-year follow up. Conclusion: Early stage breast cancer treated with IORT yields favorable QoL outcomes and minimal toxicity profiles with adequate short-term local control.
RESUMEN
Individuals with sporadic colorectal cancer (CRC) frequently harbor abnormalities in the composition of the gut microbiome; however, the microbiota associated with precancerous lesions in hereditary CRC remains largely unknown. We studied colonic mucosa of patients with familial adenomatous polyposis (FAP), who develop benign precursor lesions (polyps) early in life. We identified patchy bacterial biofilms composed predominately of Escherichia coli and Bacteroides fragilis Genes for colibactin (clbB) and Bacteroides fragilis toxin (bft), encoding secreted oncotoxins, were highly enriched in FAP patients' colonic mucosa compared to healthy individuals. Tumor-prone mice cocolonized with E. coli (expressing colibactin), and enterotoxigenic B. fragilis showed increased interleukin-17 in the colon and DNA damage in colonic epithelium with faster tumor onset and greater mortality, compared to mice with either bacterial strain alone. These data suggest an unexpected link between early neoplasia of the colon and tumorigenic bacteria.

BACKGROUND: Minority-serving hospitals have greater readmission rates after operative procedures including colectomy; however, little is known about the contribution of hospital factors to readmission risk and mortality in this setting. This study evaluated the impact of hospital factors on readmissions and inpatient mortality after colorectal resections at minority-serving hospitals in the context of patient- and procedure-related factors. METHODS: More than 168,000 patients who underwent colorectal resections in 374 California hospitals (2004-2011) were analyzed using the State Inpatient Database and American Hospital Association Hospital Survey data. Sequential logistic regression analyses were performed to determine the associations between minority-serving hospital status and 30-day, 90-day, and repeated readmissions. RESULTS: Thirty-day, 90-day, and repeated readmission rates were 11.2%, 16.9%, and 2.9%, respectively. Odds for 30-day, 90-day, and repeated readmissions after colorectal resections were 19%, 20%, and 38% more likely at minority-serving hospitals versus non-minority-serving hospitals, respectively (P < .01), after controlling for age, sex, comorbidities, year, and procedure type. Patient factors accounted for up to 65% of the observed increase in odds for readmission at minority-serving hospitals while hospital-level factors contributed roughly 40%. Inpatient mortality was significantly greater at minority-serving hospitals versus non-minority-serving hospitals (4.9% vs 3.8%; P < .001). Risk factors significantly associated with readmissions and inpatient mortality included Medicaid/Medicare primary insurance, emergent operation, and ostomy creation. Low procedure volume was significantly associated with increased odds for inpatient mortality. CONCLUSION: Patient-level factors seemed to dominate the increased readmission risk after colorectal resections at minority-serving hospitals while hospital factors were less contributory. These findings need to be further validated to shape quality improvement interventions to decrease readmissions.

OBJECTIVES: Much research has been conducted to describe medical mistakes resulting in patient harm using databases that capture these events for medical organizations. The objective of this study was to describe patients' perceptions regarding disclosure and their actions after harm. METHODS: We analyzed a patient harm survey database composed of responses from a voluntary online survey administered to patients by ProPublica, an independent nonprofit news organization, during a 1-year period (May 2012 to May 2013). We collected data on patient demographics and characteristics related to the acknowledgment of patient harms, the reporting of patient harm to an oversight agency, whether the patient or the family obtained the harm-associated medical records, as well as the presence of a malpractice claim. RESULTS: There were 236 respondents reporting a patient harm (mean age, 49.1 y). In 11.4% (27/236) of harms, an apology by the medical organization or the clinician was made. In 42.8% (101/236) of harms, a complaint was filed with an oversight agency. In 66.5% (157/236) of harms, the patient or the family member obtained a copy of the pertinent medical records. A malpractice claim was reported in 19.9% (47/236) of events. CONCLUSIONS: In this sample of self-reported patient harms, we found a perception of inadequate apology. Nearly half of patient harm events are reported to an oversight agency, and roughly one-fifth result in a malpractice claim.
