Treatment cost assessment for COVID-19 inpatients in Shenzhen, China 2020-2021: facts and suggestions.

Background: Knowledge regarding the treatment cost of coronavirus disease 2019 (COVID-19) in the real world is vital for disease burden forecasts and health resources planning. However, it is greatly hindered by obtaining reliable cost data from actual patients. To address this knowledge gap, this study aims to estimate the treatment cost and specific cost components for COVID-19 inpatients in Shenzhen city, China in 2020-2021. Methods: It is a 2 years' cross-sectional study. The de-identified discharge claims were collected from the hospital information system (HIS) of COVID-19 designated hospital in Shenzhen, China. One thousand three hundred ninety-eight inpatients with a discharge diagnosis for COVID-19 from January 10, 2020 (the first COVID-19 case admitted in the hospital in Shenzhen) to December 31, 2021. A comparison was made of treatment cost and cost components of COVID-19 inpatients among seven COVID-19 clinical classifications (asymptomatic, mild, moderate, severe, critical, convalescent and re-positive cases) and three admission stages (divided by the implementation of different treatment guidelines). The multi-variable linear regression models were used to conduct the analysis. Results: The treatment cost for included COVID-19 inpatients was USD 3,328.8. The number of convalescent cases accounted for the largest proportion of all COVID-19 inpatients (42.7%). The severe and critical cases incurred more than 40% of treatment cost on western medicine, while the other five COVID-19 clinical classifications spent the largest proportion (32%-51%) on lab testing. Compared with asymptomatic cases, significant increases of treatment cost were observed in mild cases (by 30.0%), moderate cases (by 49.2%), severe cases (by 228.7%) and critical cases (by 680.7%), while reductions were shown in re-positive cases (by 43.1%) and convalescent cases (by 38.6%). The decreasing trend of treatment cost was observed during the latter two stages by 7.6 and 17.9%, respectively. Conclusions: Our findings identified the difference of inpatient treatment cost across seven COVID-19 clinical classifications and the changes at three admission stages. It is highly suggestive to inform the financial burden experienced by the health insurance fund and the Government, to emphasize the rational use of lab tests and western medicine in the COVID-19 treatment guideline, and to design suitable treatment and control policy for convalescent cases.

Open-Design for a Smart Cover of a Night-Time Telescope for Day-Time Use.

Robotic observatories are ideal infrastructures that can be remotely accessed by scientists, amateurs, and general public for research and education in Astronomy. Its robotization is a complex process for ensuring autonomy, safety, and coordination among all subsystems. Some observatories, such as Francisco Sanchez's, are equipped with two types of telescopes: one for the night and one for the day. The night-time telescope must be protected from exposure to sunlight in order to use them in an automated way. For this purpose, this article proposes the design and construction of a smart cover that opens and closes according to the time of day. The mechatronic design covers the electronic, mechanical, and software programming, and it has been devised taking while taking the principles of open design, ease of reproduction, low-cost, and smart behaviour into account. The design has been parameterized, so that it can be adapted to telescopes of any size. The final prototype is lightweight, cost-effective, and can be built while using common 3D printing and PCB milling machines. The complete design is licensed under the GNU General Public License v3.0 and all the documentation, schematics, and software are available in public repositories, like Zenodo, GitHub, and Instructables.

Which Cost Components Influence the Cost of Palliative Care in the Last Hospitalization? A Retrospective Analysis of Palliative Care Versus Usual Care at a Swiss University Hospital.

CONTEXT: Although the number of studies on the economic impact of palliative care (PC) is growing, the great majority report costs from North America. OBJECTIVES: We aimed to provide a comprehensive overview of PC hospital cost components from the perspective of a European mixed funded health care system by identifying cost drivers of PC and quantifying their effect on hospital costs compared to usual care (UC). METHODS: We performed a retrospective, observational analysis examining cost data from the last hospitalization of patients who died at a large academic hospital in Switzerland comparing patients receiving PC vs. UC. RESULTS: Total hospital costs were similar in PC and UC with a mean difference of CHF -2777 [95% CI -12,713 to 8506, P = 0.60]. Average costs per day decreased by CHF -3224 [95% CI -3811 to -2631, P < 0.001] for PC patients with significant reduction of costs for diagnostic intervention and medication. Higher cost components for PC patients were catering, room, nursing, social counseling, and nonmedical therapists. In sensitivity analyses, when we restricted PC exposure to three days from admission, total costs and average costs per day were significantly lower for PC. CONCLUSION: Studies measuring the impact of PC on hospital costs should analyze various cost components beyond total costs to understand wanted and potentially unwanted cost-reducing effects. An international definition of a set of cost components, specific for cost-impact PC studies, may help avoid superficial and potentially dangerous cost discussions.

Uncertainty in monetary cost estimates for assessing working postures using inclinometry, observation or self-report.

OBJECTIVE: To assess uncertainty in cost estimates for collecting posture data by inclinometry, observations and self-report. METHOD: In a study addressing physical workloads at a paper mill, costs were calculated for measuring postures of twenty-eight workers during three shifts. Uncertainty in costs was assessed for all three methods as the range between an assumed best case (lowest cost) and worst case (highest cost) using scenario analysis. RESULTS: The cost for observation was larger, but also more uncertain (€16506 and €89552 in the best and worst case, respectively) than that of inclinometry (€7613 - €45896). Self-report costs were both lower and less uncertain (€3743 - €23368). CONCLUSIONS: The extent of uncertainty in cost estimates implies that observation could be less expensive than inclinometry, e.g., in a scenario where experienced observers could use existing software, while inclinometers would have to be purchased. We propose adding uncertainty assessments to cost estimates when selecting a method for measuring working postures, and offer guidance in how to proceed in a specific setting.

The Cost of Radiology Procedures Using Activity Based Costing (ABC) for Development of Cost Weights in Implementation of Casemix System in Malaysia / Jurnal Sains Kesihatan Malaysia

@#Presently there is a gross lack of information on cost and cost weights in many developing countries that implementcasemix system. Furthermore, studies that employed Activity Based Costing method (ABC) to estimate the costs of radiologyprocedures were rarely done in developing countries, including Malaysia. The main objective of this study is to determinethe costs of radiology procedures for each group in casemix system, in order to develop cost weights to be used in theimplementation of the casemix system. An economic evaluation study was conducted in all units in the Department ofRadiology in the first teaching hospital using the casemix system in Malaysia. From the 25,754 cases, 16,173 (62.8%)of them were from medical discipline. Low One Third and High One Third (L3H3) method was employed to trim theoutlier cases. Output from the trimming, 15,387 cases were included in the study. The results revealed that the totalinpatients’ charges of all the radiology procedures was RM1,820,533.00 while the cost imputed using ABC method wasRM2,970,505.54. The biggest cost component were human resources in Radiology Unit (Mobile) (57.5%), consumables(78.5%) of Endovascular Interventional Radiology (EIR) Unit, equipment (81.4%) of Magnetic Resonance Imaging (MRI)Unit, reagents (68.1%) of Medical Nuclear Unit. The one highest radiology cost weight, was for Malaysia DiagnosisRelated Group (MY-DRG®)B-4-11-II (Hepatobiliary and Pancreas Neoplasms with severity level II, 2.8301). The methodof calculation of the cost of procedures need to be revised by the hospital as findings from this study showed that the costimposed to patient is lower than the actual cost.

The economic burden of inpatients with type 2 diabetes: a case study in a Chinese hospital.

The purpose of this research was to study the components, influencing factors, and their changing trend in a Chinese hospital, so as to reduce the economic burden of inpatients with type 2 diabetes. Data were collected from 7487 cases. There were 4368 inpatients with type 2 diabetes during 2002-2012 in a Chinese hospital. Multivariate linear regression analysis was performed to explore the influencing factors of hospitalization costs. The number of inpatients and their hospitalization costs had increasing trends in the study period. The medicine, test, and examination charges were the main sources of total costs. Longer hospital stays, older ages, and more times of hospitalization led to higher medical costs. Actions should be taken on all fronts to control the rapidly increasing trend of hospitalization costs and to reduce hospital stays and the number of times of hospitalization to reduce the economic burden of diabetic inpatients.
