How can artificial intelligence boost firms' exports? evidence from China.

This paper explores the impact of artificial intelligence and industrial robots on firms' export behaviour and divides the impact mechanism into the productivity effect and labour substitution effect. It examines the effect of industrial robots on firms' export value by using Chinese Customs data, Chinese Industrial Firm data and robot data from the International Robot Federation (IRF). The main findings are as follows: Firstly, the impact of artificial intelligence and industrial robots on Chinese firms' export value is generally negative, which means the negative labour substitution effect dominates the positive productivity effect. Secondly, the impact of artificial intelligence varies significantly by industry, and the export value of firms from high-tech industries benefits from the use of industrial robots. Thirdly, the impact of artificial intelligence on firms' export value also varies by time; before 2003, the use of industrial robots showed mainly an inhibiting effect on firms' exports, which turned into a driving effect thereafter, and after 2006, industrial robots began to significantly promote firms' export. Finally, the higher the quality of export products, the more likely the use of industrial robots will be to promote firms' export value, and the higher the capital-labour ratio is, the more likely firms' export value will be to benefit from the use of artificial intelligence and industrial robots. On the basis of these findings, this study proposes promoting the productivity effect to dominate the labour substitution effect through technological progress and the improvement of export product quality.

Absence of ultimate controller and investment efficiency: Evidence from China.

In modern enterprises with a separation of powers, the ultimate controller can effectively influence the implementation of corporate strategy and operational management efficiency, as well as improve corporate governance by monitoring and limiting the management entrenchment effect within enterprises. Based on the information pertaining to ultimate controllers disclosed by enterprises in their annual reports, this study empirically tested whether the absence of the ultimate controller impacts investment efficiency using the data of Chinese A-share listed companies from 2007 to 2020. It was found that the investment efficiency of enterprises without ultimate controllers is relatively lower than those with ultimate controllers. This is reflected in the insufficient investment of enterprises without an ultimate controller. Moreover, the effect is more significant when the financial environment, internal governance environment, and external governance environment of firms are worse. The mechanism analysis demonstrated that the absence of an ultimate controller causes a more severe insider agency problem and a significantly higher degree of financing constraints, which leads to underinvestment and reduces investment efficiency of firms. The economic consequence test also found that the inefficient investment caused by the absence of ultimate controllers would damage the future value of enterprises, but would increase managers' compensation. Overall, this study suggests that ultimate controllers are an important part of a firm's internal governance, especially for monitoring management behavior and resolving agency conflicts.

Utilization of lean project management principles and health informatics to reduce operating room delays in a vascular surgery practice.

OBJECTIVES: Perioperative inefficiency can increase cost. We describe a process improvement initiative that addressed preoperative delays on an academic vascular surgery service. METHODS: First case vascular surgeries from July 2019-January 2020 were retrospectively reviewed for delays, defined as late arrival to the operating room (OR). A stakeholder group spearheaded by a surgeon-informaticist analyzed this process and implemented a novel electronic medical records (EMR) preoperative tool with improved preoperative workflow and role delegation; results were reviewed for 3 months after implementation. RESULTS: 57% of cases had first case on-time starts with average delay of 19 min. Inappropriate preoperative orders were identified as a dominant delay source (average delay = 38 min). Three months post-implementation, 53% of first cases had on-time starts with average delay of 11 min (P < 0.05). No delays were due to missing orders. CONCLUSIONS: Inconsistent preoperative workflows led to inappropriate orders and delays, increasing cost and decreasing quality. A novel EMR tool subsequently reduced delays with projected savings of $1,200/case. Workflow standardization utilizing informatics can increase efficiency, raising the value of surgical care.

Determinants of hospital inefficiency. The case of Polish county hospitals.

Local hospitals play a crucial role in the healthcare system. In this study, the efficiency of Polish county hospitals is assessed by considering characteristics of hospitals that may determine their performance, such as the form of ownership, size, and staff structure. The main goal was to analyze the effect of three possible determinants on efficiency: ownership, the presence of an Emergency Department, and the presence of an Intensive Care Unit. The study covered different subgroups of hospitals and different approaches of inputs and outputs. An input-oriented radial super-efficiency DEA model under variable returns to scale was used for the efficiency analysis, and then differences between distributions of efficient and inefficient units were evaluated using a Chi-square test. A Kruskal-Wallis test was also used to analyze differences in mean efficiency. Inefficiency scores were regressed with hospital characteristics to test for other determinants. These results did not confirm differences in efficiency concerning ownership. However, in some subgroups of hospitals, running an Emergency Department or an Intensive Care Unit had a significant effect. Tobit regression results provided additional insight into how an Emergency Department or Intensive Care Unit can affect efficiency. Both cases had an effect of increasing inefficiency, and the data suggested that the department/unit size plays an important role.

Friction Costs and the Chain of Vacancies Problem: A Novel Vacancy Multiplier Solution.

OBJECTIVES: A key criticism of applying the friction cost approach (FCA) to productivity cost estimation is its focus on a single friction period. A more accurate estimate of the friction cost of worker absence requires consideration of the chain of secondary vacancies arising from the opening of a new primary vacancy. Currently, empirical evidence on this is almost absent. We suggest an original approach to empirically estimate productivity costs that include a chain of secondary vacancies. METHODS: The vacancy multiplier is based on labor market flows and transition probabilities between states of employment, unemployment, and economic inactivity. It is a summed infinite geometric series using a common ratio et - the probability of an employed person filling a new job vacancy in a given year. We report vacancy multipliers for 30 European countries for 2011-2019. RESULTS: The average multiplier across Europe is 2.21 (standard deviation [SD] = 0.40) in 2019, meaning that every new primary vacancy created a chain of secondary vacancies that increased the primary friction cost by a factor of 2.21. The equivalent multiplier is 1.99 (SD = 0.37) between 2011 and 2019. Romania had the lowest country-specific multiplier (1.11 in 2011), and Greece the highest (4.51 in 2011). CONCLUSIONS: Our results highlight the extent of underestimation of current FCA costs, comprise a resource for future researchers, and provide an implementable formula to compute the multiplier for other countries.

A Surgeon Badge or Text Message Sign-in Intervention Improves Operating Room Start Efficiency.

BACKGROUND: Operating room (OR) efficiency, often measured by first case on-time start (FCOTS) percentage, is an important driver of perioperative team morale and the financial success of a hospital. MATERIALS AND METHODS: In this quasi-experimental study of elective surgical procedures at a single tertiary academic hospital, an intervention requiring attending surgeon attestation of availability via SMS text message or identification badge swipe was implemented. Key measures of OR efficiency were compared before and after the change. RESULTS: FCOTS percentage increased from 61.6% to 66.9% after the intervention (P = 0.01). After adjusting for patient and procedural characteristics, postintervention period remained associated with an increased odds of an on-time start (odds ratio 1.29, P = 0.01). Additionally, procedural start times from the pre- to postintervention period were significantly improved (-0.08 min/day, P = 0.009). CONCLUSIONS: Implementation of an attending surgeon text or badge sign-in process was associated with improved FCOTS percentage and earlier procedure start times.

The Impact of FASTPASS: A Collaboration With Emergency Department to Improve Management of Patients With Gallbladder Disease and Acute Appendicitis.

BACKGROUND: Efficient Emergency Department (ED) throughput depends on several factors, including collaboration and consultation with surgical services. The acute care surgery service (ACS) collaborated with ED to implement a new process termed "FASTPASS" (FP), which might improve patient-care for those with acute appendicitis and gallbladder disease. The aim of this study was to evaluate the 1-year outcome of FP. METHODS: FASTPASS is a joint collaboration between ACS and ED. ED physicians were provided with a simple check-list for diagnosing young males (<50-year old) with acute appendicitis (AA) and young males or females (<50-year old) with gallbladder disease (GBD). Once ED deemed patients fit our FP check-list, patients were directly admitted (FASTPASSed) to the observation unit. The ACS then came to evaluate the patients for possible surgical intervention. We performed outcome analysis before and after the institution of the FP. Outcomes of interest were ED length of stay (LOS), time from ED to the operating room (OR) (door-to-knife), hospital LOS (HLOS), and cost. RESULTS: During our 1-year study period, for those patients who underwent GBD/AA surgery, 56 (26%) GBD and 27 (26%) AA patients met FP criteria. Compared to the non-FP patients during FP period, FP halved ED LOS for GBD (7.4 ± 3.0 versus 3.5 ± 1.7 h, P < 0.001) and AA (6.7 ± 3.3 versus. 1.8 ± 1.6 h, P < 0.001). Similar outcome benefits were observed for door-to-knife time, HLOS, and costs. CONCLUSIONS: In this study, the FP process improved ED throughput in a single, highly-trained ER leading to an overall improved patient care process. A future study involving multiple EDs and different disease processes may help decrease ED overcrowding and improve healthcare system efficiency.

Process Mapping and Activity-Based Costing of the Intravitreal Injection Procedure.

PURPOSE/AIM OF THE STUDY: To quantify the cost of performing an intravitreal injection (IVI) utilizing activity-based costing (ABC), which allocates a cost to each resource involved in a manufacturing process. MATERIALS AND METHODS: A prospective, observational cohort study was performed at an urban, multi-specialty ophthalmology practice affiliated with an academic institution. Fourteen patients scheduled for an IVI-only visit with a retina ophthalmologist were observed from clinic entry to exit to create a process map of time and resource utilization. Indirect costs were allocated with ABC and direct costs were estimated based on process map observations, internal accounting records, employee interviews, and nationally-reported metrics. The primary outcome measure was the cost of an IVI procedure in United States dollars. Secondary outcomes included operating income (cost subtracted from revenue) of an IVI and patient-centric time utilization for an IVI. RESULTS: The total cost of performing an IVI was $128.28; average direct material, direct labor, and overhead costs were $2.14, $97.88, and $28.26, respectively. Compared to the $104.40 reimbursement set by the Centers for Medicare and Medicaid Services for Current Procedural Terminology code 67028, this results in a negative operating income of -$23.88 (-22.87%). The median clinic resource-utilizing time to complete an IVI was 32:58 minutes (range [19:24-1:28:37]); the greatest bottleneck was physician-driven electronic health record documentation. CONCLUSIONS: Our study provides an objective and accurate cost estimate of the IVI procedure and illustrates how ABC may be applied in a clinical context. Our findings suggest that IVIs may currently be undervalued by payors.

Identification of work accommodations and interventions associated with work productivity in adults with migraine: A scoping review.

OBJECTIVE: To identify factors associated with work productivity in adults with migraine, and accommodations or interventions to improve productivity or the workplace environment for them. METHODS: We conducted a scoping review by searching MEDLINE, Embase, PsycINFO, Cumulative Index of Nursing and Allied Heath Literature, and Web of Science from their inception to 14 October 2019 for studies of any design that assessed workplace productivity in adults with migraine. RESULTS: We included 26 articles describing 24 studies after screening 4139 records. Five prospective cohort studies showed that education on managing migraine in the workplace was associated with an increase in productivity of 29-36%. Two studies showed that migraine education and management in the workplace were associated with increased productivity (absenteeism decreased by 50% in one study). One prospective cohort study showed that occupational health referrals were associated with more than 50% reduction in absenteeism. Autonomy, social support, and job satisfaction were positively associated with productivity, while quantitative demands, emotional demands, job instability, and non-conducive work environment triggers are negatively associated with productivity in workers with migraine. CONCLUSION: Despite migraine being the second leading cause of disability worldwide, there is a paucity of strong data on migraine-related work factors associated with productivity.Registration: None (scoping review).

Association of long working hours and health-related productivity loss, and its differential impact by income level: A cross-sectional study of the Korean workers.

OBJECTIVES: We aimed to explore the association between long working hours and health-related productivity loss (HRPL), due to either sickness, absenteeism or presenteeism, stratified by household income level. METHODS: From January 2020 to February 2020, data were collected using a web-based questionnaire. A total of 4197 participants were randomly selected using the convenience sampling method. The nonparametric association between weekly working hours and HRPL was determined. Subsequently, a stratified analysis was conducted according to household income (1st, 2nd, and 3rd tertiles). Finally, the differences in HRPL of the different working hour groups (<40, 40, 40-51, and ≥52 hours) were investigated using a multivariate linear regression model. RESULTS: Long working hours were more significantly associated with HRPL, as compared to the 'standard' working hours (40 hours/week). A larger proportion of productivity loss was associated with the presenteeism of workers, rather than absenteeism. The relationship between HRPL and weekly working hours was more prominent in the lower household income group. CONCLUSIONS: The results of our study indicate that HRPL is associated with long working hours, especially in the lower household income group. Reducing the workload for the individual employee to a manageable level and restructuring sick leave policies to effectively counteract absenteeism and presenteeism may be a feasible option for better labor productivity and employee health.

Rewarding On Time Start Times in Operating Rooms Improves Efficiency.

BACKGROUND: The average cost of running an operating room (OR) is approximately $37.00 a minute. Therefore, every effort should be made to start in a timely manner. There are several factors at play that can cause OR delays. Attaining consistent start times is a multidisciplinary task, which requires good communication and rewards for efficiency. METHODS: At our institution, a "star system" was implemented to improve compliance with timely start times. All OR staff (scrub tech, OR nurse, anesthesiologist, and physician) get 1 star for every on time start. Once a person attains 10 stars, they are awarded a $20 gift card to a local bakery/coffee shop. RESULTS: There was a significant difference in the 3 months pre- and post-implementation of the star system in regard to starting on time (54% vs. 71%, P-value .047), and there were significantly less late starts within 6-10 minutes (14% vs. 4%, P-value = <.01). There was no statistically significant difference in late starts >11 minutes or when comparing days of the week. The most common reasons for delay are as follows: surgeon running late (23%), anesthesiologist tardiness (11%), patient is late (9%), preoperative orders, or test not completed (7%). CONCLUSION: The significant increase in the number of cases that start on time after implementation of the star system leads us to believe that late start times are multifactorial, and that incentives are a positive way to encourage the OR team to start on time.

Ambulatory Access: Improving Scheduling Increases Patient Satisfaction and Revenue.

BACKGROUND: Even before seeing a physician, patients must first gain access to the hospital system. At large hospitals with high patient volumes, access to specialty care can pose a particular challenge. This study examines the effects of specific initiatives to increase clinic capacity, appointment use, and ease of scheduling on both patient satisfaction and hospital revenue. METHODS: In 2017, a task force at a large, multidisciplinary pediatric hospital instituted a number of initiatives to increase patient access to ambulatory specialty clinics. Clinic sessions were standardized to a 4-hour template, and unscheduled, "held" appointment slots were required to be made available ("flipped") 72 hours before the appointment. A patient-centered electronic scheduling platform was also implemented. Patient satisfaction was assessed using Press Ganey scores. Revenue estimates were calculated for increases in "new" and "return" patient appointments. RESULTS: Total new appointment slots increased by over 44 percent, with over 53,000 appointments added annually. The number of held appointment slots declined by 93 percent. A total of 17,996 annual appointments were added in surgical subspecialties, and an additional 14,756 more surgical appointments were completed. Over 2000 appointments were scheduled by means of the online patient portal. Press Ganey "ease-of-scheduling" scores increased from 57 percent to 72 percent over the intervention period. Hospitalwide, these initiatives generated an estimated $8.3 million in revenue opportunity. CONCLUSION: Standardizing clinic sessions and optimizing clinic availability generates new appointment opportunities, improves patient experience, and increases hospital revenue.

A Smart Service Platform for Cost Efficient Cardiac Health Monitoring.

AIM: In this study we have investigated the problem of cost effective wireless heart health monitoring from a service design perspective. SUBJECT AND METHODS: There is a great medical and economic need to support the diagnosis of a wide range of debilitating and indeed fatal non-communicable diseases, like Cardiovascular Disease (CVD), Atrial Fibrillation (AF), diabetes, and sleep disorders. To address this need, we put forward the idea that the combination of Heart Rate (HR) measurements, Internet of Things (IoT), and advanced Artificial Intelligence (AI), forms a Heart Health Monitoring Service Platform (HHMSP). This service platform can be used for multi-disease monitoring, where a distinct service meets the needs of patients having a specific disease. The service functionality is realized by combining common and distinct modules. This forms the technological basis which facilitates a hybrid diagnosis process where machines and practitioners work cooperatively to improve outcomes for patients. RESULTS: Human checks and balances on independent machine decisions maintain safety and reliability of the diagnosis. Cost efficiency comes from efficient signal processing and replacing manual analysis with AI based machine classification. To show the practicality of the proposed service platform, we have implemented an AF monitoring service. CONCLUSION: Having common modules allows us to harvest the economies of scale. That is an advantage, because the fixed cost for the infrastructure is shared among a large group of customers. Distinct modules define which AI models are used and how the communication with practitioners, caregivers and patients is handled. That makes the proposed HHMSP agile enough to address safety, reliability and functionality needs from healthcare providers.

Private money-making indulgence and inefficiency of primary healthcare in Nigeria: a qualitative study of health workers' absenteeism.

OBJECTIVES: Generating additional personal income is common with primary healthcare (PHC) workforce in Nigeria, which could be because of the inconsistencies marring their monthly salaries. Therefore, this study investigates the drivers of private economic activities of PHC providers in the public sector, and the links to absenteeism, as well as inefficiency of PHC facilities in Nigeria. METHODS: A qualitative study design was used to collect data from 30 key-informants using in-depth interviews. They were selected from 5 PHC facilities across three local government areas in Enugu state, south-eastern Nigeria. Data were analysed thematically, and guided by phenomenology. RESULTS: Findings showed that majority of the health workers were involved in different private money-making activities. A main driver was inconsistencies in salaries, which makes it difficult for them to routinely meet their personal and household needs. As a result, PHC facilities were found less functional. CONCLUSIONS: Absenteeism of PHC providers can be addressed if efforts are made to close justifiable gaps that cause health workers to struggle informally. Such lesson can be instructive to low- and middle-income countries in strengthening their health systems.

Administrative Burden and Costs of Prior Authorizations in a Dermatology Department.

Importance: Insurance companies use prior authorizations (PAs) to address inappropriate prescribing or unnecessary variations in care, most often for expensive medications. Prior authorizations negatively affect patient care and add costs and administrative burden to dermatology offices. Objective: To quantify the administrative burden and costs of dermatology PAs. Design, Setting, and Participants: The University of Utah Department of Dermatology employs 2 full-time and 8 part-time PA staff. In this cross-sectional study at a large academic department spanning 11 clinical locations, these staff itemized all PA-related encounters over a 30-day period in September 2016. Staff salary and benefits were publicly available. Data were analyzed between December 2018 and August 2019. Main Outcomes and Measures: Proportion of visits requiring PAs, median administrative time to finalize a PA (either approval or denial after appeal), and median cost per PA type. Results: In September 2016, 626 PAs were generated from 9512 patient encounters. Staff spent 169.7 hours directly handling PAs, costing a median of $6.72 per PA. Biologic PAs cost a median of $15.80 each and took as long as 31 business days to complete. The costliest PA equaled 106% of the associated visit's Medicare reimbursement rate. Approval rates were 99.6% for procedures, 78.9% for biologics, and 58.2% for other medications. After appeal, 5 of 23 (21.7%) previously denied PAs were subsequently approved. Conclusions and Relevance: Prior authorizations are costly to dermatology practices and their value appears limited for some requests. Fewer unnecessary PAs and appeals might increase practice efficiency and improve patient outcomes.

Diet type influences the gut microbiome and nutrient assimilation of Genetically Improved Farmed Tilapia (Oreochromis niloticus).

Nile tilapia, Oreochromis niloticus is the third most commonly farmed finfish species in the world, accounting for nearly 5% of global aquaculture production. In the past few decades much of the success of this species has been attributed to the development and distribution of Genetically Improved Farmed Tilapia (GIFT). Despite the increasing availability of GIFT, the productivity of small-scale farming remains highly variable, particularly in developing nations. Commercial fish-feed pellets can increase fish farm productivity; however, many small-scale farmers rely on other means of feeding fish due to the high cost and limited availability of commercial fish feed pellets. Therefore, understanding how locally-sourced feeds affect the production of GIFT is an important step towards improving feeding practices, particularly for farmers with low financial capital. This study used stable isotope analysis (SIA) and 16S rRNA gene sequencing to compare the effects of a locally-sourced vegetable-based diet and commercial pellet-based diets on the relative condition, nutrient assimilation patterns and gastrointestinal microbiota of GIFT. GIFT fed a locally-sourced diet were smaller, and in a significantly poorer condition than those fed with commercial fish feeds. SIA showed no differences in dietary carbon between the two diets; however, δ13C, poor fish condition and the abundance of specific bacterial taxa (of such as Fusobacteria) were correlated. SIA revealed that GIFT fed locally-sourced diets that predominantly consisted of vegetables were significantly enriched in δ15N despite a perceived lack of dietary protein. This enrichment suggests that GIFT fed a locally-sourced diet may be supplementing their diet via cannibalism, a behaviour representative of poor farming practice. Overall this study highlights the need to increase the availability of suitable GIFT feeds in developing nations. The development a low-cost feed alternative could improve the success of small-scale GIFT farmers in PNG, increasing both food and income security within the region.
