How did episiotomy rates change from 2007 to 2014? Population-based study in France
International audienceBACKGROUND: Since the 2000s, selective episiotomy has been systematically recommended worldwide. In France, the recommended episiotomy rate in vaginal deliveries is less than 30%. The aims of this study were to describe the evolution of episiotomy rates between 2007 and 2014, especially for vaginal deliveries without instrumental assistance and to assess individual characteristics and birth environment factors associated with episiotomy.METHODS: This population-based study included all hospital discharge abstracts for all deliveries in France from 2007 to 2014. The use of episiotomy in vaginal deliveries was identified by one code in the French Common Classification of Medical Procedures. The episiotomy rate per department and its evolution is described from 2007 to 2014. A mixed model was used to assess associations with episiotomy for non-operative vaginal deliveries and the risk factors related to the women's characteristics and the birth environment.RESULTS: There were approximately 540,000 non-operative vaginal deliveries per year, in the study period. The national episiotomy rate for vaginal deliveries overall significantly decreased from 26.7% in 2007 to 19.9% in 2014. For non-operative deliveries, this rate fell from 21.1% to 14.1%. For the latter, the use of episiotomy was significantly associated with breech vaginal delivery (aOR = 1.27 [1.23-1.30]), epidural analgesia (aOR = 1.45 [1.43-1.47]), non-reassuring fetal heart rate (aOR = 1.47 [1.47-1.49]), and giving birth for the first time (aOR = 3.85 [3.84-4.00]).CONCLUSIONS: The episiotomy rate decreased throughout France, for vaginal deliveries overall and for non-operative vaginal deliveries. This decrease is probably due to proactive changes in practices to restrict the number of episiotomies, which should be performed only if beneficial to the mother and the infant
Does catheter-associated urinary tract infection increase mortality in critically ill patients?
International audienceOBJECTIVE: To produce an accurate estimate of the association between catheter-associated urinary tract infection (UTI) and intensive care unit (ICU) and hospital mortality, controlling for major confounding factors. DESIGN: Nested case-control study in a multicenter cohort (the OutcomeRea database). SETTING: Twelve French medical or surgical ICUs. METHODS: All patients admitted between January 1997 and August 2005 who required the insertion of an indwelling urinary catheter. Patients who developed catheter-associated UTI (ie, case patients) were matched to control patients on the basis of the following criteria: sex, age (+/- 10 years), SAPS (Simplified Acute Physiology Score) II score (+/- 10 points), duration of urinary tract catheterization, and presence or absence of diabetes mellitus. The association of catheter-associated UTI with ICU and hospital mortality was assessed by use of conditional logistic regression. RESULTS: Of the 3,281 patients who had an indwelling urinary catheter, 298 (9%) developed at least 1 episode of catheter-associated UTI. The incidence density of catheter-associated UTI was 12.9 infections per 1,000 catheterization-days. Crude ICU mortality rates were higher among patients with catheter-associated UTI, compared with those without catheter-associated UTI (32% vs 25%, P=.02); the same was true for crude hospital mortality rates (43% vs 30%, P<.01). After matching and adjustment, catheter-associated UTI was no longer associated with increased mortality (ICU mortality: odds ratio [OR], 0.846 [95% confidence interval {CI}, 0.659-1.086]; P=.19 and hospital mortality: OR, 0.949 [95% CI, 0.763-1.181]; P=.64). CONCLUSION: After carefully controlling for confounding factors, catheter-associated UTI was not found to be associated with excess mortality among our population of critically ill patients in either the ICU or the hospital
Outcomes in severe sepsis and patients with septic shock: pathogen species and infection sites are not associated with mortality.
International audienceOBJECTIVES: We evaluated the respective influence of the causative pathogen and infection site on hospital mortality from severe sepsis related to community-, hospital-, and intensive care unit-acquired infections. DESIGN: We used a prospective observational cohort 10-yr database. We built a subdistribution hazards model with corrections for competing risks and adjustment for potential confounders including early appropriate antimicrobial therapy. SETTING: Twelve intensive care units. PATIENTS: We included 4,006 first episodes of acquisition-site-specific severe sepsis in 3,588 patients. INTEVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We included 1562 community-acquired, 1432 hospital-acquired, and 1012 intensive care unit-acquired episodes of severe sepsis. After adjustment, we found no independent associations of the causative organism, multidrug resistance of the causative organism, infection site, or presence of bacteremia with mortality. Early appropriate antimicrobial therapy was consistently associated with better survival in the community-acquired (0.64 [0.51-0.8], p = .0001), hospital-acquired (0.72 [0.58-0.88], p = .0011), and intensive care unit-acquired (0.79 [0.64-0.97], p = .0272) groups. CONCLUSION: The infectious process may not exert as strong a prognostic effect when severity, organ dysfunction and, above all, appropriateness of early antimicrobials are taken into account. Our findings emphasize the importance of developing valid recommendations for early antimicrobial therapy
Quality of life in patients aged 80 or over after ICU discharge.
International audienceINTRODUCTION: Our objective was to describe self-sufficiency and quality of life one year after intensive care unit (ICU) discharge of patients aged 80 years or over. METHODS: We performed a prospective observational study in a medical-surgical ICU in a tertiary non-university hospital. We included patients aged 80 or over at ICU admission in 2005 or 2006 and we recorded age, admission diagnosis, intensity of care, and severity of acute and chronic illnesses, as well as ICU, hospital, and one-year mortality rates. Self-sufficiency (Katz Index of Activities of Daily Living) was assessed at ICU admission and one year after ICU discharge. Quality of life (WHO-QOL OLD and WHO-QOL BREF) was assessed one year after ICU discharge. RESULTS: Of the 115 consecutive patients aged 80 or over (18.2% of admitted patients), 106 were included. Mean age was 84 +/- 3 years (range, 80 to 92). Mortality was 40/106 (37%) at ICU discharge, 48/106 (45.2%) at hospital discharge, and 73/106 (68.9%) one year after ICU discharge. In the 23 patients evaluated after one year, self-sufficiency was unchanged compared to the pre-admission status. Quality of life evaluations after one year showed that physical health, sensory abilities, self-sufficiency, and social participation had slightly worse ratings than the other domains, whereas social relationships, environment, and fear of death and dying had the best ratings. Compared to an age- and sex-matched sample of the general population, our cohort had better ratings for psychological health, social relationships, and environment, less fear of death and dying, better expectations about past, present, and future activities and better intimacy (friendship and love). CONCLUSIONS: Among patients aged 80 or over who were selected at ICU admission, 80% were self-sufficient for activities of daily living one year after ICU discharge, 31% were alive, with no change in self-sufficiency and with similar quality of life to that of the general population matched on age and sex. However, these results must be interpreted cautiously due to the small sample of survivors
Does Catheter-Associated Urinary Tract Infection Increase Mortality in Critically Ill Patients?
Predicting the risk of documented ventilator-associated pneumonia for benchmarking: construction and validation of a score.
International audienceOBJECTIVES:: To build and validate a ventilator-associated pneumonia risk score for benchmarking. The rate of ventilator-associated pneumonia varies widely with case-mix, a fact that has limited its use for measuring intensive care unit performance. METHODS:: We studied 1856 patients in the OUTCOMEREA database treated at intensive care unit admission by endotracheal intubation followed by mechanical ventilation for >48 hrs; they were allocated randomly to a training data set (n = 1233) or a validation data set (n = 623). Multivariate logistic regression was used. Calibration of the final model was assessed in both data sets, using the Hosmer-Lemeshow chi-square test and receiver operating characteristic curves. MEASUREMENTS AND MAIN RESULTS:: Independent risk factors for ventilator-associated pneumonia were male gender (odds ratio = 1.97, 95% confidence interval = 1.32-2.95); SOFA at intensive care unit admission (8 [5.81 (3.2-10.52)], no use within 48 hrs after intensive care unit admission of parenteral nutrition (2.29, 1.52-3.45), no broad-spectrum antimicrobials (2.11, 1.46-3.06); and mechanical ventilation duration (15 days (225.6, 54.3-936.7). Tests in the training set showed good calibration and good discrimination (area under the curve-receiver operating characteristic curve = 0.881), and both criteria remained good in the validation set (area under the curve-receiver operating characteristic curve = 0.848) and good calibration (Hosmer-Lemeshow chi-square = 9.98, p = .5). Observed ventilator-associated pneumonia rates varied across intensive care units from 9.7 to 26.1 of 1000 mechanical ventilation days but the ratio of observed over theoretical ventilator-associated pneumonia rates was >1 in only two intensive care units. CONCLUSIONS:: The ventilator-associated pneumonia rate may be useful for benchmarking provided the ratio of observed over theoretical rates is used. External validation of our prediction score is needed
Infectious risk associated with arterial catheters compared with central venous catheters.
International audienceBACKGROUND: Scheduled replacement of central venous catheters and, by extension, arterial catheters, is not recommended because the daily risk of catheter-related infection is considered constant over time after the first catheter days. Arterial catheters are considered at lower risk for catheter-related infection than central venous catheters in the absence of conclusive evidence. OBJECTIVES: To compare the daily risk and risk factors for colonization and catheter-related infection between arterial catheters and central venous catheters. METHODS: We used data from a trial of seven intensive care units evaluating different dressing change intervals and a chlorhexidine-impregnated sponge. We determined the daily hazard rate and identified risk factors for colonization using a marginal Cox model for clustered data. RESULTS: We included 3532 catheters and 27,541 catheter-days. Colonization rates did not differ between arterial catheters and central venous catheters (7.9% [11.4/1000 catheter-days] and 9.6% [11.1/1000 catheter-days], respectively). Arterial catheter and central venous catheter catheter-related infection rates were 0.68% (1.0/1000 catheter-days) and 0.94% (1.09/1000 catheter-days), respectively. The daily hazard rate for colonization increased steadily over time for arterial catheters (p = .008) but remained stable for central venous catheters. Independent risk factors for arterial catheter colonization were respiratory failure and femoral insertion. Independent risk factors for central venous catheter colonization were trauma or absence of septic shock at intensive care unit admission, femoral or jugular insertion, and absence of antibiotic treatment at central venous catheter insertion. CONCLUSIONS: The risks of colonization and catheter-related infection did not differ between arterial catheters and central venous catheters, indicating that arterial catheter use should receive the same precautions as central venous catheter use. The daily risk was constant over time for central venous catheter after the fifth catheter day but increased significantly over time after the seventh day for arterial catheters. Randomized studies are needed to investigate the impact of scheduled arterial catheter replacement
Outcome of ICU patients with Clostridium difficile infection
INTRODUCTION: As data from Clostridium difficile infection (CDI) in intensive care unit (ICU) are still scarce, our objectives were to assess the morbidity and mortality of ICU-acquired CDI. METHODS: We compared patients with ICU-acquired CDI (watery or unformed stools occurring ≥ 72 hours after ICU admission with a stool sample positive for C. difficile toxin A or B) with two groups of controls hospitalized at the same time in the same unit. The first control group comprised patients with ICU-acquired diarrhea occurring ≥ 72 hours after ICU admission with a stool sample negative for C. difficile and for toxin A or B. The second group comprised patients without any diarrhea. RESULTS: Among 5,260 patients, 512 patients developed one episode of diarrhea. Among them, 69 (13.5%) had a CDI; 10 (14.5%) of them were community-acquired, contrasting with 12 (17.4%) that were hospital-acquired and 47 (68%) that were ICU-acquired. A pseudomembranous colitis was associated in 24/47 (51%) ICU patients. The median delay between diagnosis and metronidazole administration was one day (25(th )Quartile; 75(th )Quartile (0; 2) days). The case-fatality rate for patients with ICU-acquired CDI was 10/47 (21.5%), as compared to 112/443 (25.3%) for patients with negative tests. Neither the crude mortality (cause specific hazard ratio; CSHR = 0.70, 95% confidence interval; CI 0.36 to 1.35, P = 0.3) nor the adjusted mortality to confounding variables (CSHR = 0.81, 95% CI 0.4 to 1.64, P = 0.6) were significantly different between CDI patients and diarrheic patients without CDI. Compared to the general ICU population, neither the crude mortality (SHR = 0.64, 95% CI 0.34 to 1.21, P = 0.17), nor the mortality adjusted to confounding variables (CSHR = 0.71, 95% confidence interval (CI) 0.38 to 1.35, P = 0.3), were significantly different between the two groups. The estimated increase in the duration of stay due to CDI was 8.0 days ± 9.3 days, (P = 0.4) in comparison to the diarrheic population, and 6.3 days ± 4.3 (P = 0.14) in comparison to the general ICU population. CONCLUSIONS: If treated early, ICU-acquired CDI is not independently associated with an increased mortality and impacts marginally the ICU length of stay
