Ordering Patterns and Costs of Specialized Laboratory Testing by Hospitalists and House Staff in Hospitalized Patients With HIV at a County Hospital: An Opportunity for Diagnostic Stewardship.

ABSTRACT: Background:Inpatient HIV care often requires specialized laboratory testing with which practitioners may not be familiar. In addition, computerized physician order entry allows for ordering tests without understanding test indications, but it can also provide a venue for education and diagnostic stewardship. Methods:All charts of HIV-positive patients hospitalized at a tertiary care public safety net hospital in Houston, Texas, between January 1, 2014, and June 30, 2014, were reviewed for a set list of laboratory tests. Appropriateness of test ordering was assessed by 2 providers. Cost estimates for each test were obtained from Medicaid and a national nonprofit health care charge database. Results:A total of 274 HIV-positive patients were admitted 429 times in the 6-month study period. During the study period, 45% of the study laboratory tests ordered were not indicated. A total of 532 hepatitis serologies were ordered, only 52% of which were indicated. Overall, 71 serum qualitative cytomegalovirus (CMV) polymerase chain reactions (PCRs) and eight CMV quantitative PCRs were ordered, with most (85%) qualitative PCRs ordered for nonspecific signs of infection (eg, fever). Other tests ordered without clear indications included Aspergillus IgE (7), serum Epstein-Barr virus (EBV) PCR (5), parvovirus serology (7), and Toxoplasma IgM (18). Overall, the estimated laboratory cost of inappropriate testing over the study period was between $14 000 and $92 000, depending on which cost database was used. Conclusions:Many tests ordered in HIV-positive inpatients do not have indications, representing a substantial source of health care waste and cost and potentially leading to inappropriate treatment. Opportunities exist to decrease waste through education of trainees and hospitalists and through implementation of diagnostic stewardship via the electronic medical record.

Project description:ImportanceAs US hospital expenditures continue to rise, understanding drivers of high-severity billing for hospitalized patients among inpatient physicians is critically important.ObjectiveTo evaluate high-severity billing trends of Medicare beneficiaries treated by hospitalists vs nonhospitalists.Design setting and participantsThis cohort study used Medicare fee-for-service claims of hospitalized patients from 2009 through 2018 to compare the proportion of high-severity billing between general medicine physicians classified as hospitalists vs nonhospitalists across initial, subsequent, and discharge hospital encounters. We compared physicians within the same hospital using hospital fixed effects and adjusted for patient demographics and comorbidities. Changes in the billing practices were assessed by investigating differences in slopes using an interaction term between physician type and time. Analyses were conducted between August 2021 and January 2022.ExposuresTreatment by hospitalists vs nonhospitalists.Main outcomes and measuresHigh-severity billing for initial, subsequent, and discharge hospital encounters.ResultsThe sample included 3 121 260 and 1 855 678 Medicare beneficiaries treated by hospitalists vs nonhospitalists, respectively. In each year, mean age, proportion female, proportion Black and Hispanic dual status, and mean number of chronic conditions were similar among those treated by hospitalists vs nonhospitalists (standardized mean difference < .01). The number of hospitalists grew by 76%, from 23 390 in 2009 to 41 084 in 2018, whereas nonhospitalists decreased by 43.6% (53 758 to 30 289). The proportion of encounters performed by hospitalists increased for the initial hospital encounters (46.3% to 76%), subsequent encounters (46.8% to 76.7%), and discharge encounters (46.1% to 78.5%) over the 10-year period. The proportion of high-severity billing across the hospital, subsequent, and discharge encounters was consistently higher among hospitalists relative to nonhospitalists across all years. Compared with the trends for nonhospitalists, the proportion of high-severity billing grew by 0.46% per year (95% CI, 0.44% to 0.49%; P < .001) for initial encounters, 0.38% per year (95% CI, 0.37% to 0.39%; P < .001) for subsequent encounters, and by 1.1% per year (95% CI, 1.1% to 1.15%; P < .001) for discharge encounters among hospitalists.Conclusions and relevanceIn this cohort study of Medicare fee-for-service beneficiaries treated in hospitals, high-severity billing increased over time for hospital encounters at higher rates for hospitalists than for nonhospitalists. These differences do not appear to be explained by patient complexity. The increase in the number of hospitalists over time may be contributing to rising national costs related to hospital care.

Project description:ImportancePediatric hospital medicine is a relatively new and growing specialty. However, research remains inconclusive on outcomes for inpatients cared for by pediatric hospitalists compared with those cared for by general pediatricians.ObjectiveTo analyze outcomes, adverse events (AEs), and types of AEs associated with care provided for pediatric patients by hospitalists vs general pediatricians.Design, setting, and participantsThis cross-sectional study used data from the medical records of a US urban academic children's hospital comprising 1423 hospitalizations between January 1, 2009, and August 31, 2015, for 57 diagnoses of patients cared for by either a hospitalist or general pediatrician. General pediatricians worked primarily in the hospital's outpatient clinic, serving a few inpatient weeks per year, and were not the patients' primary care physician. Data analysis was performed from July 1, 2017, to October 10, 2018.Main outcomes and measuresOutcomes were length of stay, total costs, 30-day readmission rates, and AEs. Adverse events were documented by International Classification of Diseases, Ninth Revision, Clinical Modification codes determined by review of medical records. Adverse event categories were drug events, infections, and device-related AEs. Generalized linear models were used to analyze patient outcomes, with standard errors clustered by physician. Models were adjusted for patient characteristics, including Chronic Condition Indicators. Models were estimated with and without adjustment for physician characteristics.ResultsThe data set contained 1423 hospitalizations among 726 female patients and 697 male patients (mean [SD] age, 6.1 [6.3] years). Hospitalists cared for 870 patients, and general pediatricians cared for 553 patients. Among the physicians, there were 57 women and 38 men; physicians were a mean (SD) 11.1 (8.1) years out of medical school. Patients cared for by general pediatricians were younger than those cared for by hospitalists (mean [SD] age, 5.4 [6.0] vs 6.5 [6.4] years; P = .001) but had similar mean (SD) Chronic Condition Indicator scores (1.5 [1.0] vs 1.5 [1.0]). A total of 33 of 56 general pediatricians (58.9%) and 24 of 39 hospitalists (61.5%) were women (P = .006), and general pediatricians were in practice twice as long as hospitalists on average (mean [SD], 16.0 [10.3] vs 7.9 [3.8] years out of medical school; P < .001). In multivariate models adjusting for patient-level features, there were no significant differences between general pediatricians and hospitalists for mean length of stay (4.7 vs 4.6 days), total costs ($14 490 vs $15 200), and estimated 30-day readmission rate (8.9% vs 6.4%), and results were similar with adjustments for physician characteristics. Device-related AEs were higher among hospitalists (3.0% vs 1.1%; odds ratio, 0.34; 95% CI, 0.12-1.00); this association became nonsignificant after adjusting for physician experience.Conclusions and relevanceGeneral pediatrician and hospitalist inpatient care had similar length of stay, total costs, and readmission rates. However, AEs differed between hospitalists and general pediatricians, with device-related AEs more common among hospitalists, which may be associated with hospitalists' fewer years in practice. Such findings can inform hospitals in planning their inpatient staffing and patient safety oversight.
