biostudies-literatureUnknown109(3)Iyer RBACKGROUND: Most studies use hospital data to calculate postoperative complication rates (PCRs). We report on improving PCR estimates through use of patient-reporting. METHODS: A prospective cohort study of major surgery performed at 10 UK gynaecological cancer centres was undertaken. Hospitals entered the data contemporaneously into an online database. Patients were sent follow-up letters to capture postoperative complications. Grade II-V (Clavien-Dindo classification) patient-reported postoperative complications were verified from hospital records. Postoperative complication rate was defined as the proportion of surgeries with a Grade II-V postoperative complication. RESULTS: Patient replies were received for 1462 (68%) of 2152 surgeries undertaken between April 2010 and February 2012. Overall, 452 Grade II-V (402 II, 50 III-V) complications were reported in 379 of the 1462 surgeries. This included 172 surgeries with 200 hospital-reported complications and 231 with 280 patient-reported complications. All (100% concordance) 36 Grade III-V and 158 of 280 (56.4% concordance) Grade II patient-reported complications were verified on hospital case-note review. The PCR using hospital-reported data was 11.8% (172 out of 1462; 95% CI 11-14), patient-reported was 15.8% (231 out of 1462; 95% CI 14-17.8), hospital and verified patient-reported was 19.4% (283 out of 1462; 95% CI 17.4-21.4) and all data were 25.9% (379 out of 1462; 95% CI 24-28). After excluding Grade II complications, the hospital and patient verified Grade III-V PCR was 3.3% (48 out of 1462; 95% CI 2.5-4.3). CONCLUSION: This is the first prospective study of postoperative complications we are aware of in gynaecological oncology to include the patient-reported data. Patient-reporting is invaluable for obtaining complete information on postoperative complications. Primary care case-note review is likely to improve verification rates of patient-reported Grade II complications.British journal of cancer623-32https://www.ebi.ac.uk/biostudies/studies/S-EPMC3738134biostudies-literaturePatient-reporting improves estimates of postoperative complication rates: a prospective cohort study in gynaecological oncology.PMC3738134Lopes ANevin JIyer RBurnell MDas NLeeson SOlaitan ALinder AGornall RHillaby KDesai RRufford BThackeray ARyan AMenon UMould TNordin AReynolds KListon RGentry-Maharaj AMeechan DBeardmore-Gray AWood NShanbhag SfalsePatient-reporting improves estimates of postoperative complication rates: a prospective cohort study in gynaecological oncology.BACKGROUND: Most studies use hospital data to calculate postoperative complication rates (PCRs).
