Continuous quality improvement efforts decrease postoperative ileus rates

Paralytic ileus in the United States: A cross-sectional study from the national inpatient sample

Introduction:

Paralytic ileus is a common clinical condition leading to significant morbidity and mortality. Most studies to date have focused on postoperative ileus, a common but not exclusive cause of the condition. There are limited epidemiological data regarding the incidence and impact of paralytic ileus and its relationship to other clinical conditions. In this cross-sectional study, we analyzed national inpatient hospitalization trends, demographic variation, cost of care, length of stay, and mortality for paralytic ileus hospitalizations as a whole.

Methods:

The National Inpatient Sample database was used to identify all hospitalizations with the diagnosis of paralytic ileus (International Classification of Diseases, 9th Revision code 560.1) as primary or secondary diagnosis during the period from 2001 to 2011. Statistical analysis was performed using Cochran–Armitage trend test, Wilcoxon rank sum test, and Poisson regression.

Results:

In 2001, there were 362,561 hospitalizations with the diagnosis of paralytic ileus as compared to 470,110 in 2011 (p < 0.0001). The age group 65–79 years was most commonly affected by paralytic ileus throughout the study period. In-hospital all-cause mortality decreased from 6.03% in 2001 to 5.10% in 2011 (p < 0.0001). However, the average cost of care per hospitalization increased from US$19,739 in 2001 to US$26,198 in 2011 (adjusted for inflation, p < 0.0001).

Conclusion:

There was a significant rise in the number of hospitalizations of paralytic ileus with increased cost of care and reduced all-cause mortality.

What is the value and impact of quality and safety teams? A scoping review

BACKGROUND

The purpose of this study was to conduct a scoping review of the literature about the establishment and impact of quality and safety team initiatives in acute care.

METHODS

Studies were identified through electronic searches of Medline, Embase, CINAHL, PsycINFO, ABI Inform, Cochrane databases. Grey literature and bibliographies were also searched. Qualitative or quantitative studies that occurred in acute care, describing how quality and safety teams were established or implemented, the impact of teams, or the barriers and/or facilitators of teams were included. Two reviewers independently extracted data on study design, sample, interventions, and outcomes. Quality assessment of full text articles was done independently by two reviewers. Studies were categorized according to dimensions of quality.

RESULTS

Of 6,674 articles identified, 99 were included in the study. The heterogeneity of studies and results reported precluded quantitative data analyses. Findings revealed limited information about attributes of successful and unsuccessful team initiatives, barriers and facilitators to team initiatives, unique or combined contribution of selected interventions, or how to effectively establish these teams.

CONCLUSIONS

Not unlike systematic reviews of quality improvement collaboratives, this broad review revealed that while teams reported a number of positive results, there are many methodological issues. This study is unique in utilizing traditional quality assessment and more novel methods of quality assessment and reporting of results (SQUIRE) to appraise studies. Rigorous design, evaluation, and reporting of quality and safety team initiatives are required.

Pre-operative hypoalbuminemia is a major risk factor for postoperative complications following rectal cancer surgery

AIM: To determine the relationship between pre-operative hypoalbuminemia and the development of complications following rectal cancer surgery, as well as postoperative bowel function and hospital stay.

METHODS: The medical records of 244 patients undergoing elective oncological resection for rectal adenocarcinoma at Siriraj Hospital during 2003 and 2006 were reviewed. The patients had pre-operative serum albumin assessment. Albumin less than 35 g/L was recognized as hypoalbuminemia. Postoperative outcomes, including mortality, complications, time to first bowel movement, time to first defecation, time to resumption of normal diet and length of hospital stay, were analyzed.

RESULTS: The patients were 139 males (57%) and 105 females (43%) with mean age of 62 years. Fifty-six patients (23%) had hypoalbuminemia. Hypoalbuminemic patients had a significantly larger tumor size and lower body mass index compared with non-hypoalbuminemic patients (5.5 vs 4.3 cm; P < 0.001 and 21.9 vs 23.2 kg/m²; P = 0.02, respectively). Thirty day postoperative mortality was 1.2%. Overall complication rate was 25%. Hypoalbuminemic patients had a significantly higher rate of postoperative complications (37.5% vs 21.3%; P = 0.014). In univariate analysis, hypoalbuminemia and ASA status were two risk factors for postoperative complications. In multivariate analysis, hypoalbuminemia was the only significant risk factor (odds ratio 2.22, 95% CI 1.17-4.23; P < 0.015). Hospitalization in hypoalbuminemic patients was significantly longer than that in non-hypoalbuminemic patients (13 vs 10 d, P = 0.034), but the parameters of postoperative bowel function were not significantly different between the two groups.

CONCLUSION: Pre-operative hypoalbuminemia is an independent risk factor for postoperative complications following rectal cancer surgery.

Complications and costs after high-risk surgery: where should we focus quality improvement initiatives?

BACKGROUND

Data on the relative clinical and economic impact of postoperative complications are needed in order to direct quality improvement efforts.

STUDY DESIGN

Patients undergoing two high-risk surgical procedures, hepatectomy (n = 569) and esophagectomy (n = 366), from 1994 to 1998 were included. Data were abstracted from the Maryland hospital discharge database. Relative resource use was determined using median regression, adjusting for patient comorbidities and other case-mix variables.

RESULTS

A total of 935 patients were studied. Overall in-hospital mortality was 6.1%; complication rate was 38.4%. Median cost for all patients was $14,527 (interquartile range $10,936-$21,412) and length of stay 9 days (interquartile range 7-13 days). Median hospital cost was increased for patients with complications ($16,868 versus $12,861; p < 0.001). In the multivariate analysis, several complications remained associated with increased cost. Acute renal failure ($25,219), septicemia ($18,852), and myocardial infarction ($9,573) were associated with the greatest increase in resource use. But because the incidence of each complication varies, the attributable fraction of total resource use was highest for acute renal failure (19%), septicemia (16%), and surgical complications (16%).

CONCLUSIONS

Complications are independently associated with increased resource use after high-risk surgery. Population-based studies may be valuable in determining the relative economic importance of postoperative complications. Quality improvement efforts for these complications should be prioritized based on both the incidence of the complication and its independent contribution to increased resource use.
