The transition to ICD-10 has occurred with no loss of data quality, with data showing a high level of reliability and adherence to coding standards. When consideration is given to the nature of the analysis, administrative data can provide highly reliable population-based estimates of hospitalization rates.
An "incidence flag" is essential to identify those adverse events for which a hospital has unambiguous responsibility. Using such a flag, secondary analysis of administrative data can provide hospital quality assurance programmes with a comprehensive view of all adverse events (not just "sentinel" events) at a reasonable cost and with more timely results than more intensive methods can achieve. Although the method is likely to underestimate the true rate of adverse events (in particular, by not capturing adverse events which only manifest after discharge), in this study of Australian hospitals, rates of adverse events were found to be similar to those derived from studies using manual review of patient records.
Objective:To determine the clinical characteristics, outcomes and longitudinal trends of sepsis occurring in cancer patients. Method:Retrospective study using statewide Victorian Cancer Registry data linked to various administrative datasets.Results: Among 215,763 incident cancer patients, incidence of sepsis within one year of cancer diagnosis was estimated at 6.4%. The incidence of sepsis was higher in men, younger patients, patients diagnosed with haematological malignancies and those with de novo metastatic disease. Of the 13,316 patients with a first admission with sepsis, 55% had one or more organ failures, 29% required care within an intensive care unit and 13% required mechanical ventilation. Treatments associated with the highest sepsis incidence were stem cell/bone marrow transplant (33%), major surgery (4.4%), chemotherapy (1.1%) and radical radiotherapy (0.6%). The incidence of sepsis with organ failure increased between 2008 and 2015, while 90day mortality decreased.Conclusions: Sepsis in patients with cancer has high mortality and occurs most frequently in the first year after cancer diagnosis. Implications for public health:The number of cancer patients diagnosed with sepsis is expected to increase, causing a substantial burden on patients and the healthcare system.
BackgroundThe use of routine hospital data for understanding patterns of adverse outcomes has been limited in the past by the fact that pre-existing and post-admission conditions have been indistinguishable. The use of a 'Present on Admission' (or POA) indicator to distinguish pre-existing or co-morbid conditions from those arising during the episode of care has been advocated in the US for many years as a tool to support quality assurance activities and improve the accuracy of risk adjustment methodologies. The USA, Australia and Canada now all assign a flag to indicate the timing of onset of diagnoses. For quality improvement purposes, it is the 'not-POA' diagnoses (that is, those acquired in hospital) that are of interest.MethodsOur objective was to develop an algorithm for assessing the validity of assignment of 'not-POA' flags. We undertook expert review of the International Classification of Diseases, 10th Revision, Australian Modification (ICD-10-AM) to identify conditions that could not be plausibly hospital-acquired. The resulting computer algorithm was tested against all diagnoses flagged as complications in the Victorian (Australia) Admitted Episodes Dataset, 2005/06. Measures reported include rates of appropriate assignment of the new Australian 'Condition Onset' flag by ICD chapter, and patterns of invalid flagging.ResultsOf 18,418 diagnosis codes reviewed, 93.4% (n = 17,195) reflected agreement on status for flagging by at least 2 of 3 reviewers (including 64.4% unanimous agreement; Fleiss' Kappa: 0.61). In tests of the new algorithm, 96.14% of all hospital-acquired diagnosis codes flagged were found to be valid in the Victorian records analysed. A lower proportion of individual codes was judged to be acceptably flagged (76.2%), but this reflected a high proportion of codes used <5 times in the data set (789/1035 invalid codes).ConclusionAn indicator variable about the timing of occurrence of diagnoses can greatly expand the use of routinely coded data for hospital quality improvement programmes. The data-cleaning instrument developed and tested here can help guide coding practice in those health systems considering this change in hospital coding. The algorithm embodies principles for development of coding standards and coder education that would result in improved data validity for routine use of non-POA information.
Clinical documentation improvement (CDI) roles are being increasingly created in Australian hospitals. It is important to understand what good clinical documentation is and who is responsible for it as well as what these roles potentially offer our health system. This article explores the role of a CDI specialist, the benefits and pitfalls of clinical documentation improvement programs, and mounts an argument that health information managers and clinical coders are uniquely placed to fill these roles in Australian hospitals.
