ABSTRACT
BACKGROUND: Healthcare-associated infection compromises patient safety. Compliance with hand hygiene (HH) guidelines has been shown to be an effective method of reducing infection; however, it remains suboptimal and poorer among doctors compared to other healthcare workers. The aim of this study is to determine the relationship between an individualised observational hand hygiene audit (OHHA) and feedback intervention with observed HH compliance. METHODS: We used a retrospective interrupted time series design using OHHA data from a five-year period, 2011-2015. OHHA indicated poorer HH compliance among doctors than other healthcare workers in a 345-bed acute private hospital. An increase in orthopaedic surgical site infection prompted additional auditing of the orthopaedic unit further identifying substandard HH compliance among orthopaedic surgeons. In addition to ongoing HH interventions, an individualised hand hygiene audit and feedback intervention focusing on consultant orthopaedic surgeons was implemented. Observed HH compliance improved. The intervention was then extended to include all consultant doctors at the study site. Audit was implemented by trained clinical nurse managers during clinical rounds. Written audit feedback was provided by the infection prevention and control team. RESULTS: HH compliance increased significantly among both orthopaedic surgeons and other consultant doctors, P < 0.05. CONCLUSION: An individualised audit and feedback intervention was effective in improving compliance. Incorporation of OHHA with individualised feedback into routine daily practice needs to be considered as a quality improvement opportunity. This study has the potential to inform other audit and feedback interventions to maximise effectiveness and ensure implementation.
ABSTRACT
PURPOSE: In malignant mesothelioma (MM), radiologic assessment of disease status is difficult. Both soluble mesothelin-related peptide (SMRP) and osteopontin (OP) have utility in distinguishing MM from benign pleural disease. We evaluated whether SMRP and OP also correlated with the disease course of MM. PATIENTS AND METHODS: Serial plasma samples from patients with MM were prospectively collected, and SMRP and OP levels were measured. Radiologic tests across time periods showing disease progression, stability, or shrinkage were compared with corresponding changes in SMRP/OP levels. RESULTS: From 41 patients, 165 samples were collected (range, 2 to 10; median 4). At study entry, 37 of 41 patients had measurable disease, of whom 92% (34 of 37) had elevated baseline SMRP levels; four of 41 patients had no evidence of recurrence and each had normal baseline SMRP levels. In 21 patients receiving systemic therapy, percentage change in SMRP more than 10% correlated with the radiologic assessment by a trained thoracic radiologist (P < .001), by formal Response Evaluation Criteria in Solid Tumors (RECIST; P = .008), or by modified RECIST (P < .001). All seven patients who underwent surgical resection with negative margins had elevated preoperative SMRP levels that fell to normal postoperatively. Rising SMRP was observed in all patients with radiologic disease progression. No associations were found with OP. CONCLUSION: Percentage changes in SMRP levels, but not changes in OP levels, are a potentially useful marker of disease course. These findings should be validated prospectively for a role as an objective adjunctive measure of disease course in both clinical trials and clinical practice.
