Implementation of a clinical pathway for emergency department out-patient management of deep vein thrombosis.

There is good evidence demonstrating that outpatient management of deep venous thrombosis (DVT) is feasible and safe. However, few emergency departments in Ireland have implemented care pathways for outpatient management of DVT. The aim of this study was to examine the safety and efficacy of implementing an Emergency Department (ED)- care pathway for outpatient management of patients with DVT. A retrospective observational study of this care pathway introduced at our institution was performed. The primary outcome measure was the number of hospital admissions avoided by using the care pathway. Two hundred and eighty-four patients presenting to the ED with suspected lower limb DVT, were managed using the care pathway over a 6 month period. Forty-nine patients (17%) had a DVT diagnosed. Thirty-nine patients (81%) were suitable for outpatient DVT management. Ten patients (19%) were admitted to hospital. At 3 months there were no reported cases of the following complications: missed DVT, pulmonary embolism or death.

Physician consensus on preventability and predictability of readmissions based on standard case scenarios.

BACKGROUND: Policy makers struggle with unplanned readmissions as a quality indicator since integrating preventability in such indicators is difficult. Most studies on the preventability of readmissions questioned physicians whether they consider a given readmission to be preventable, from which conclusions on factors predicting preventable readmissions were derived. There is no literature on the interobserver agreement of physician judgement. AIM: To assess the degree of agreement among physicians regarding predictability and preventability of medical readmissions. DESIGN: An online survey based on eight real-life case scenarios was distributed to European physicians. METHODS: Physicians were requested to rate from the first four (index admission) scenarios whether they expected these patients to be readmitted within 30 days (the predictability). The remaining four cases, describing a readmission, were used to assess the preventability. The main outcome was the degree of agreement among physicians determined using the intra class correlation coefficient (ICC). RESULTS: 526 European medical physicians completed the survey. Most physicians had internal medicine as primary specialism. The median years of clinical experience was 11. ICC for predictability of readmission was 0.67 (moderate to good) and ICC for preventability of readmission was 0.13 (poor). CONCLUSION: There was moderate to good agreement among physicians on the predictability of readmissions while agreement on preventability was poor. This study indicates that assessing preventability of readmissions based solely on the judgement of physicians is far from perfect. Current literature on the preventability of readmissions and conclusions derived on the basis of physician opinion should be interpreted with caution.

Readmissions of medical patients: an external validation of two existing prediction scores.

BACKGROUND: Hospital readmissions are increasingly used as a quality indicator with a belief that they are a marker of poor care and have led to financial penalties in UK and USA. Risk scoring systems, such as LACE and HOSPITAL, have been proposed as tools for identifying patients at high risk of readmission but have not been validated in international populations. AIM: To perform an external independent validation of the HOSPITAL and LACE scores. DESIGN: An unplanned secondary cohort study. METHODS: Patients admitted to the medical admission unit at the Hospital of South West Jutland (10/2008-2/2009; 2/2010-5/2010) and the Odense University Hospital (6/2009-8/2011) were analysed. Validation of the scores using 30 day readmissions as the endpoint was performed. RESULTS: A total of 19 277 patients fulfilled the inclusion criteria. Median age was 67 (range 18-107) years and 8977 (46.6%) were female. The LACE score had a discriminatory power of 0.648 with poor calibration and the HOSPITAL score had a discriminatory power of 0.661 with poor calibration. The HOSPITAL score was significantly better than the LACE score for identifying patients at risk of 30 day readmission (P < 0.001). The discriminatory power of both scores decreased with increasing age. CONCLUSION: Readmissions are a complex phenomenon with not only medical conditions contributing but also system, cultural and environmental factors exerting a significant influence. It is possible that the heterogeneity of the population and health care systems may prohibit the creation of a simple prediction tool that can be used internationally.
