Aim:To determine whether the survival of patients with suspected acute pulmonary embolism (PE) relates to radiological probability of acute PE assessed using lung scintigraphy scans (LSS). Methods: Lung scintigraphy scan results from a venous thromboembolism database were categorised as high, indeterminate or low probability using the modified PIOPED criteria and corresponding chest X-rays (CXRs) as normal or abnormal. Mortality data on these cases were obtained from the General Register Office for Scotland, and survival was analysed using the Kaplan-Meier method. Results: Of the 1,818 LSS analysed, 941 (51.8%) were normal, 532 (29.3%) indeterminate and 345 (19.0%) high probability. After an adjustment for age and gender, no significant survival difference was found between patients with normal and high probability LSS (p=0.182). However, patients with indeterminate LSS had significantly lower survival than patients in the other groups. This difference persisted after adjustment for CXR result. Conclusions: Indeterminate LSS results are associated with a poor prognosis. Careful follow-up of patients with inderminate LSS would appear to be justified.
Enhanced Recovery After Surgery (ERAS) incorporates multi-modal interventions that synergistically improve patient outcome. Its goals include improving patients functionally pre-operatively, reducing the stress of surgery intra-operatively to facilitate early return to daily activities. We conducted a pilot study at our unit recruiting patients undergoing elective coronary artery bypass grafting (CABG) into the Cardiac ERAS (C-ERAS) pilot and compared them with the patients undergoing CABG meeting the ERAS criteria but who not included the C-ERAS pilot (Control).Materials and Methods: 122 C-ERAS patients were compared to 91 control patients who underwent CABG only from the period of July 2015 to September 2016. All C-ERAS patients received pre-operative counselling by a dedicated ERAS Practitioner to manage expectations of the patient journey, health promotion and pre-operative optimisation advice. Emphasis was made on educating the patient on daily goals for recovery and patients were followed up daily by the ERAS practitioner post-operatively.Results: There were 122 patients in the C-ERAS group and 91 patients in the control group. The mean age was 63.6±9.9 years. 181(85%) of the patients were males. After adjusting for the abovementioned confounders, C-ERAS patients had a shorter length of stay that was statistically significant. (2.36 days shorter (95% CI; 1.01-3.7 days; p<0.01). The difference in mean bed day costs was £1153.70 (95% CI, £553.70-£1753.7; p<0.01) less in the C-ERAS cohort. Conclusion:This study highlighted that C-ERAS is a safe and feasible pathway to reduce in-hospital stay with no difference in complications and readmission rates compared to routine management of patients. There was also a significant cost saving with the C-ERAS pathway mimicking the results in enhanced recovery programmes in the other surgical specialities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
