Surveillance of healthcare-associated infections in Piemonte, Italy: results from a second regional prevalence study.

BACKGROUND: A prevalence survey of healthcare-associated infections (HAIs) was previously performed in the Piemonte region in 2000. In the decade following the survey, many studies were performed at both the regional and hospital levels, and training courses were developed to address issues highlighted by the survey. In 2010, a second regional prevalence study was performed. The aim of this paper is to present the results of the second prevalence study and discuss them within the context of the HAI prevention and control programmes that have been implemented in the decade since the original survey was conducted. METHODS: The study involved all public hospitals in the Piemonte region. Uni- and multivariate analyses were performed to assess the main risk factors associated with HAIs, including both overall and site-specific infections. RESULTS: A total of 7841 patients were enrolled: 6.8% were affected by at least one HAI. The highest prevalence of HAIs was found in intensive care units (18.0%, 95% CI 14.0-22.6), while UTIs presented the highest relative frequency (26.7%), followed by respiratory tract infections (21.9%). The age of the patient, hospital size and urinary and central venous catheter status were significantly associated with HAIs. CONCLUSIONS: The study results showed an increase in HAI prevalence, despite prevention and control efforts, as well as training implemented after the first regional survey. Nevertheless, these data are consistent with the current literature. Furthermore, despite its limits, the prevalence approach remains an important means for involving healthcare workers, emphasising HAIs and revealing critical problems that need be addressed.

Side-to-side stapled anastomosis strongly reduces anastomotic leak rates in Crohn's disease surgery.

PURPOSE: Anastomotic configuration may influence anastomotic leak rates. The aim of this study was to determine whether a side-to-side stapled ileocolonic anastomosis produces lower anastomotic leak rates than those with a handsewn end-to-end ileocolonic anastomosis after ileocecal or ileocolonic resection for Crohn's disease. METHODS: A series of 122 consecutive patients underwent elective ileocecal or ileocolonic resection with ileocolonic anastomosis for Crohn's disease from January 1998 to June 2003: 71 had handsewn end-to-end anastomosis and 51 had side-to-side stapled anastomosis. The choice between the two anastomoses was left to the surgeon's preference. A retrospective analysis was performed to assess if there was any difference in anastomotic leak rates. RESULTS: The two groups were comparable in terms of age, gender, preoperative presence of abscess or fistula, history of smoking, and albumin levels. More patients were taking steroids in the handsewn group than in the stapled group. In the handsewn group there were 10 anastomotic leaks (14.1 percent) and in the stapled group there was 1 anastomotic leak (2.0 percent) (risk difference, +12.1 percent; 95 percent confidence interval, 1.7-22.2; P = 0.02). Anastomotic configuration was the sole variable that influenced anastomotic leak rates at univariate analysis. Mortality was 1.4 percent in the handsewn group and 0 percent in the stapled group. Complications other than anastomotic leak developed in 11 patients in the hand-sewn group and in 6 patients in the stapled group. Mean postoperative hospital stay was 12.3 days in the handsewn group and 9.7 days in the stapled group (P = 0.03). Excluding those patients who had an anastomotic leak, the difference was still present (handsewn group, 10.1 days; stapled group, 9.1 days; P = 0.04). CONCLUSION: Although confirmation from randomized, controlled trials is required, side-to-side stapled anastomosis seems to substantially decrease anastomotic leak rates in surgical patients with Crohn's disease, compared with handsewn end-to-end anastomosis. Postoperative hospital stay decreased in the stapled anastomosis group, and this was not entirely a result of decreased anastomotic leak rates.

[Evaluation of quality of care through hospital discharge reports: an example of rectal cancer surgery]. / Valutazione di qualità dell'assistenza attraverso la scheda di dimissione ospedaliera: un esempio sulla chirurgia dei tumori del retto.

This study was undertaken to evaluate the usefulness of hospital discharge data for monitoring the impact of a regional practice guideline on treatment of colorectal cancer. The aims of the study were: i) estimating process and outcome indicators; ii) exploring the relationship between patient and hospital characteristics and these indicators. Odds ratios (OR) and 95% confidence intervals (CI) were adjusted for all risk factors analysed. All 3,614 patients undergoing potentially curative resection for rectal cancer in 75 hospitals in Piedmont (Italy) between 1997 and 2000 were included. Occurrences of abdominoperineal resections (APR), postoperative complications, reinterventions and hospital mortality were 16.2%, 11.0%, 5.5% and 4.4%, respectively. APR was performed more frequently in patients with distant metastases or urgently admitted and by hospitals with a lower volume of cases (< 25 per year) compared to hospital with more than 50 cases per year (OR = 1.50, CI = 1.16-1.94). The strongest predictors for mortality and complications were: older age, distant metastases and urgency of admission. Incidence of complications and of reinterventions was also increased among males and in patients with lesions of the lower rectum. The rate of complications showed an increasing trend during the period, from 8.5% to 14.5% likely reflecting improvement in coding during time. Low hospital workload was associated to a reduced risk of complications and reinterventions, but there was evidence of underreporting of secondary diagnoses and procedures in smaller hospitals. Outcome indicator based on secondary diagnoses and procedures are of limited value in monitoring improvement of care since they reflect also differences in coding during time and among providers.
