Validation of the Canadian Institute for Health Information Diagnostic Codes for Benign Gynaecologic Surgery.

We investigated the validity of the 10th Revision Canadian modification of International Statistical Classification of Disease and Related Health Problems (ICD-10-CA) diagnostic codes for surgery for benign gynaecologic conditions in the Canadian Institute for Health Information Discharge Abstract Database (CIHI-DAD), the main source of routinely collected data in Canada. Reabstracted data from patient charts was compared to ICD-10-CA codes and measures of validity were calculated with 95% confidence intervals. A total of 1068 procedures were identified. More objective, structural diagnoses (fibroids, prolapse) had higher sensitivity and near-perfect Kappa coefficients, while more subjective, symptomatic diagnoses (abnormal uterine bleeding, pelvic pain) had lower sensitivity and moderate-substantial Kappa coefficients. Specificity, positive predictive values, and negative predictive values were generally high for all diagnoses. These findings support the use of CIHI-DAD data for gynaecologic research.

Diagnosis of Endometriosis at Laparoscopy: A Validation Study Comparing Surgeon Visualization with Histologic Findings.

OBJECTIVE: This study aimed to evaluate the validity of laparoscopic visualization for the diagnosis of endometriosis compared with histopathology. METHODS: We conducted a retrospective chart review at a tertiary care hospital in Canada for the period of April 1, 2016 to March 31, 2017. Of 1069 women, 96 were selected for having undergone laparoscopic visualization and concurrent histopathological biopsy for suspected endometriosis. Standard measures of validity for diagnostic tests (sensitivity, specificity, positive predictive and negative predictive values, accuracy) were used. RESULTS: Mean age of the 96 women included was 40 ± 7.2 years, and median gravidity and parity were 1 (IQR 0-3) and 0 (IQR 0-2), respectively. Common symptoms were abdominal and pelvic pain (41.7%), menstrual bleeding concerns (34.4%), dysmenorrhea (29.2%), and infertility (8.3%). Approximately one-third of women had endometriomas (31.3%), while more than half had deep infiltrating endometriosis (59.4%). The diagnosis of endometriosis was made by surgeons at laparoscopic visualization in 82.3% of women and by histopathology in 74.0%. Using histopathology as the gold standard, sensitivity for laparoscopic visualization was 90.1% (95% CI 81.0-95.1), while specificity was 40.0% (95% CI 23.4-59.3). Positive and negative predictive values were 81.0% (95% CI 71.0-88.1) and 58.8% (95% CI 36.0-78.4), respectively; and the accuracy was 77.1% (95% CI 67.7-84.4). CONCLUSION: Although laparoscopic visualization had relatively high sensitivity and positive predictive value, its specificity and negative predictive value were relatively low. These findings support the use of laparoscopic visualization with histopathological analysis for accurate diagnosis of endometriosis.

A Validation of Hysterectomy Procedural Codes in the Canadian Institute for Health Information Discharge Abstract Database.

OBJECTIVE: The Canadian Institute of Health Information (CIHI) Discharge Abstract Database (DAD) is the main source of routinely collected data for gynaecologic surgery in Canada and is increasingly used for research. These data are prone to error as they were originally collected for administrative purposes, and they therefore should be validated for clinical research. The objective of this study was to validate hysterectomy codes from the DAD at a single institution. METHODS: This was a retrospective observational study using an existing hospital database. We obtained a consecutive sample of all gynaecologic procedures performed at The Ottawa Hospital from April 2016 to March 2017 using the DAD. Patient data, including diagnosis, procedure type, concomitant procedure, and surgical approach, were reabstracted from records. These data were compared with the DAD Canadian Classification of Health Interventions (CCI) codes using sensitivity, specificity, positive predictive value (PPV), and κ coefficient with associated 95% confidence intervals (CIs). RESULTS: Of 1068 gynaecologic procedures, 639 hysterectomies were performed: 39.2% vaginally, 35.4% laparoscopically, and 25.4% abdominally. Median patient age was 46 years (IQR 41-54 y). The κ, sensitivity, specificity, and PPV for all hysterectomies were 0.92 (95% CI 0.90-0.95), 95.1% (95% CI 93.2-96.7), 97.9% (95% CI 96.6-99.3), and 98.5% (95% CI 97.6-99.5), respectively. The κ coefficients for vaginal, laparoscopic, and abdominal hysterectomy were 0.91 (95% CI 0.88-0.94), 0.92 (95% CI 0.89-0.95), and 0.92 (95% CI 0.89-0.95), respectively. Agreement for sub-total hysterectomy and bilateral salpingectomy with oophorectomy was excellent, with κ exceeding 0.80. The level of agreement for salpingectomy alone was poor, though specificity and PPV were high. CONCLUSIONS: Our study suggests that hysterectomy-associated CCI codes in CIHI's DAD have a high level of validity for clinical research purposes.

[Practice in forensic psychiatry: A proposed interdisciplinary model.]

Although professional practice in forensic psychiatric environments is, in our opinion, extremely complex and requires the input of different disciplines, conceptual or theoretical models guiding this practice remain rare or poorly adapted. In this article, we propose an interdisciplinary model of practice to correct this deficiency. The objectives of this article are: to report on the literature review conducted; to report, as faithfully as possible, on our general consultation process with employees practicing in a forensic psychiatric institution; and, finally, to propose an interdisciplinary practice model resulting from this general consultation within the organization.

Comparison of outcomes between induction of labor and spontaneous labor for term breech - A systemic review and meta analysis.

OBJECTIVES: Few studies have assessed the impact of induction of labor on breech presentation. This study aims to summarize the effect of induction of labor of breech presentation on perinatal morbidity. METHODS: Literature review was done in Medline, Embase, Web of science and Cochrane Library up to 20 October 2017. Randomized control studies, cohort studies, and case control publishing studies comparing induction of labor versus spontaneous labor of singleton live breech birth were included. Perinatal morbidity was calculated by RevMan 5 and presented by pooled odds ratio with 95% confidence intervals. RESULTS: Cesarean section rate and neonatal intensive care unit admission were increased in induction of breech labor as compared with spontaneous breech labor. No significant difference in umbilical cord blood base excess ≤ -12 mmol/L, Apgar 5 min < 7, Apgar 5 min < 4, umbilical cord blood PH < 7, neonatology unit admission, maternal fever, and intrapartum stillbirth between the two groups was found. CONCLUSIONS: Induction of breech labor has higher cesarean section rate and NICU perinatal morbidity compared to spontaneous breech labor. The neonatal outcomes were otherwise similar across both groups. Eligibility for induction of breech labor needs to be assessed carefully according to individual situation.
