RESUMO
Background: A consensus on the changing pattern of healthcare efficiency in China is current absent. This study tried to identify temporal fluctuations in healthcare efficiency from 2012 to 2021, and conducted a comparative analysis on the performance of 31 regions in China using region-level balanced panel data. Methods: Employing three-stage data envelopment analysis (DEA) as the analytical framework, we measured healthcare efficiency and its changes using the directional slacks-based measure and global Malmquist-luenberger (GML) indexes. We also decomposed the sources of healthcare inefficiency and extended our analysis to changes in healthcare efficiency across different primary medical service levels and regional economic development tiers. Results: The average efficiency score of medical institutions (0.956) was slightly higher than that of hospitals (0.930). We found that the average GML indexes of medical institutions in China stood at 0.990, while the average technical change (TC) index was 0.995 and the average efficiency change (EC) index was 0.998 from 2012 to 2021. The GML indexes, TC indexes, and EC indexes of hospitals were 1.002, 1.009, and 0.994, respectively. The healthcare inefficiency for both inputs and desirable outputs in medical institutions was primarily attributed to the redundant numbers of institutions, outpatient visits slacks and inpatient surgery volume slacks, accounting for 50.040, 49.644, and 28.877%, respectively. The undesirable output inefficiency values of medical institutions concerning in-hospital mortality stood at 0.012, while the figure for hospital regarding the average length of stay (LOS) was 0.002. Additionally, healthcare efficiency in both medical institutions and hospitals exhibited an upward trend from 2012 to 2021, corresponding to an increase in the volume of primary medical services, primary medical staff, and the total gross domestic product (GDP). Conclusion: Total factor productivity (TFP) of medical services declined in China from 2012 to 2021. The excessive number of medical institutions and the slack of medical service volumes were the main sources of healthcare inefficiency. Regions prioritizing primary medical services and boasting higher GDP levels exhibited superior healthcare efficiency. These findings are expected to inform policymakers' efforts in building a value-based and efficient health service system in China.

BACKGROUND: Anal squamous cell carcinoma is rare, in general, but considerably higher in HIV-infected men who have sex with men. There is no consensus on the screening of at-risk populations. OBJECTIVE: This study aimed to determine the incidence rates of anal squamous cell carcinoma and the efficacy of a screening program. DESIGN: This is a cohort study (SeVIHanal/NCT03713229). SETTING: This study was conducted at an HIV outpatient clinic in Seville, Spain. PATIENTS: From 2004 to 2017, all patients with at least 1 follow-up visit were analyzed (follow-up group), including a subgroup of men who have sex with men who participated in a specialized program for screening and treating anal neoplasia (SCAN group) from 2011 onward. MAIN OUTCOME MEASURES: The primary outcome measure was the incidence rate of anal squamous cell carcinoma. RESULTS: Of the 3878 people living with HIV included in the follow-up group, 897 were transferred to the SCAN group; 1584 (41%) were men who have sex with men. Total follow-up was 29,228 person-years with an overall incidence rate for anal squamous cell carcinoma of 68.4/100,000 person-years (95% CI, 46.7-97.4). The changes in the incidence rate/100,000 person-years (95% CI) over time was 20.7 (3.40-80.5) for 2004 to 2006, 37.3 (13.4-87.3) for 2007 to 2010, and 97.8 (63.8-144.9) for 2011 to 2017 (p < 0.001). The strongest impact on the incidence of anal squamous cell carcinoma was made by the lack of immune restoration (adjusted incidence rate ratio (95% CI): 6.59 (4.24-10); p < 0.001), the Centers for Disease Control and Prevention category C (adjusted incidence rate ratio (95% CI): 7.49 (5.69-9.85); p < 0.001), and non-men who have sex with men (adjusted incidence rate ratio (95% CI): 0.07 (0.05-0.10); p < 0.001) in a Poisson analysis. From 2010 to 2017, incidence rates (95% CI) of anal squamous cell carcinoma within the SCAN group and the men who have sex with men of the follow-up group were 95.7 (39.6-202) and 201 (101-386)/100,000 person-years (adjusted incidence rate ratio (95% CI): 0.30 (0.23-0.39); p<0.001). The incidence rate ratio (95% CI) including non-men who have sex with men in the follow-up group was 0.87 (0.69-1.11); p = 0.269. LIMITATIONS: Adherence to the visits could not be quantified. CONCLUSION: Incidence rates of anal squamous cell carcinoma in people living with HIV increased significantly from 2004 to 2017, especially in men who have sex with men who were not being screened. Participation in the SCAN program significantly reduced the incidence of anal squamous cell carcinoma in men who have sex with men, in whom focus should be placed, especially on those presenting with Centers for Disease Control and Prevention category C and advanced immune suppression.

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.

INTRODUCTION: A capacity and demand improvement initiative commenced in January 2019 with the goal of reducing the growing outpatient waiting list for magnetic resonance imaging (MRI) at Counties Manukau District Health Board (CMDHB). Initial work showed that the capacity (MRI machines and staff) actually outstripped demand, which challenged pre-existing assumptions. This became the basis for interventions to improve efficiency in the department. Interventions undertaken can be split into three distinct categories: (1) matching capacity to demand, (2) waiting list segmentation and (3) redesigning operational systems. METHODS: A capacity and demand time series during 2019 and 2020 was used as the basis for improving waiting list and operational systems. A combination of the Model for Improvement and Lean principles were used to embed operational improvements. Multiple small tests of change were implemented to various aspects of the MRI waiting list process. Staff engagement was central to the success of the quality improvement (QI) initiatives. The radiological information system (RIS) provided the bulk of the data, and this was supplemented with manual data collection. RESULTS: The number of people waiting for an MRI scan decreased from 1,954 at the start of the project to 413 at its conclusion-an overall reduction of 75%. Moreover, the average waiting time reduced from 96.4 days to 23.1. Achieving the Ministry of Health's (MoH) Priority 2 (P2) target increased from 23% to 87.5%. CONCLUSION: A partnership between Ko Awatea and the radiology department at CMDHB, examining capacity and demand for MRI and using multiple QI techniques, successfully and sustainably reduced the MRI waiting list over a two-year period. The innovative solutions to match capacity to demand may be instructive for other radiology departments, and other waiting list scenarios.

BACKGROUND: Acute care surgery (ACS) model of care delivery has many benefits. However, since the ACS surgeon has limited control over the volume, timing, and complexity of cases, traditional metrics of operating room (OR) efficiency almost always measure ACS service as "inefficient." The current study examines an alternative method-performance fronts-of evaluating changes in efficiency and tests the following hypotheses: (1) in an institution with a robust ACS service, performance front methodology is superior to traditional metrics in evaluating OR throughput/efficiency, and (2) introduction of an ACS service with block time allocation will improve OR throughput/efficiency. METHODS: Operating room metrics 1-year pre-ACS implementation and post-ACS implementation were collected. Overall OR efficiency was calculated by mean case volumes for the entire OR and ACS and general surgery (GS) services individually. Detailed analysis of these two specific services was performed by gathering median monthly minutes-in block, out of block, after hours, and opportunity unused. The two services were examined using a traditional measure of efficiency and the "fronts" method. Services were compared with each other and also pre-ACS implementation and post-ACS implementation. RESULTS: Overall OR case volumes increased by 5% (999 ± 50 to 1,043 ± 46: p < 0.05) with almost all of the increase coming through ACS (27 ± 4 to 68 ± 16: p < 0.05). By traditional metrics, ACS had significantly worse median efficiency versus GS in both periods: pre (0.67 [0.66-0.71] vs. 0.80 [0.78-0.81]) and post (0.75 [0.53-0.77] vs. 0.83 [0.84-0.85]) (p < 0.05). As compared with the pre, GS efficiency improved significantly in post (p < 0.05), but ACS efficiency remained unchanged (p > 0.05). The alternative fronts chart demonstrated the more accurate picture with improved efficiency observed for GS, ACS, and combined. CONCLUSION: In an institution with a busy ACS service, the alternative fronts methodology offers a more accurate evaluation of OR efficiency. The provision of an OR for the ACS service improves overall throughput/efficiency.

PURPOSE: To reduce the total clinic visit duration among retina providers in an academic ophthalmology department. METHODS: All patient encounters across all providers in the department were analyzed to determine baseline clinic visit duration time, defined as the elapsed time between appointment time and checkout. To increase photography capacity, a major bottleneck identified through root cause analysis, four interventions were implemented: training ophthalmic technicians to perform fundus photography in addition to optical coherence tomographies, relocating photography equipment to be adjacent to examination rooms, procuring three additional Optos widefield retinal photography units, and shifting staff schedules to better align with that of the providers. These interventions were implemented in the clinics of two retina providers. RESULTS: The average baseline visit duration for all patients across all providers was 87 minutes (19,550 patient visits). The previous average visit duration was 80 minutes for Provider 1 (557 patient visits) and 81 minutes for Provider 2 (1,246 patient visits). In the 4 weeks after interventions were implemented, the average visit duration decreased to 60 minutes for Provider 1 and 57 minutes for Provider 2. CONCLUSION: A systematic approach and a multidisciplinary team resulted in targeted, cost-effective interventions that reduced total visit durations.

SUMMARY: The cancellation of large numbers of surgical procedures because of the coronavirus disease 2019 (COVID-19) pandemic has drastically extended wait lists and negatively affected patient care and experience. As many facilities resume clinical work owing to the currently low burden of disease in our community, we are faced with operative booking protocols and procedures that are not mathematically designed to optimize efficiency. Using a subset of artificial intelligence called "machine learning," we have shown how the use of operating time can be optimized with a custom Python (a high-level programming language) script and an open source machine-learning algorithm, the ORTools software suite from the Google AI division of Alphabet Inc. This allowed the creation of customized models to optimize the efficiency of operating room booking times, which resulted in a reduction in nursing overtime of 21% - a theoretical cost savings of $469 000 over 3 years.

Hospitals are under increased pressure to address both financial and capacity constraints to improve their clinical operations. Effective capacity management programs have become a key driver of clinical operations for managing the flow of patients into and out of the hospital. Many high-functioning medical centers have developed capacity management programs to strategically address patient throughput. Discharging patients from the hospital is one fundamental, but complex, patient flow initiative for efficient patient throughput. Despite advances in optimizing patient flow, there is a lack of understanding associated with the structure and processes to efficiently discharge patients. This article outlines a discharge timeliness project where advanced practice providers are principal leaders of designing a safe and efficient patient discharge prototype. Design thinking was used to develop a patient discharge prototype that included 6 key areas that led to improved discharge times on a cardiac surgery step-down unit. High tech solutions were incorporated into the electronic medical record system to enhance communication across phases of care and inform the interdisciplinary team of patient progress.

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.

BACKGROUND: System delay (SD) is a leading cause of advanced stage of disease and poor prognosis among Brazilian breast cancer patients. METHODS: Cox regression and Kaplan-Meier analysis were used to identify variables that contributed to SD among 128 breast cancer patients. Time intervals between first medical consultation and treatment initiation were compared among patients of two referral centres: Patients of a referral centre with outsourced (FAP), respectively, integrated (HNL) diagnostic services. RESULTS: Women who used a specialized private clinic at the beginning of patient flow had an 2.32 fold increased chance (95% CI: 1.17 - 4.60; p = 0.016) of hospital admission within 90 days after first medical consultation, compared to women who used a public health care provider (HCP). Of 73 and 34 patients of the FAP hospital and the HNL, respectively, 10 (13.7%) and 11 (32.5%) used one HCP prior to hospital admission (p = 0.000). The median time between first medical consultation and treatment initiation was 150 days. The median time between first medical consultation and hospital admission was 136.0 and 52.0 days for patients of the FAP hospital, respectively the HNL (p < 0.050). The median time between first medical consultation and diagnostic mammography was 36.5 and 23.0 days for patients from the FAP hospital and the HNL (p < 0.050). CONCLUSIONS: Usage of public diagnostic services was associated with increased SD, whereas the usage of private diagnostic services diminished it. The usage of a lower number of HCPs accelerated patient flow.

INTRODUCTION: Scientometrics analyzes scientific publications through bibliometric and computational techniques, whereby productivity and impact indicators are generated. OBJECTIVE: To propose a multidimensional methodology in order to obtain the scientometric profile of the National Cancer Institute (INCan), Mexico, and rank it with regard to other national health institutions. METHOD: Using the LabSOM software and the ViBlioSOM methodology based on artificial neural networks, the INCan scientific production indexed in the Web of Science from 2007 to 2017 was analyzed. The multidimensional scientometric profile of the Institute was obtained and compared with that of other national health institutions. RESULTS: In terms of productivity, INCan ranks fourth among the 10 Mexican public health institutions indexed in the Web of Science; in the normalized impact ranking, it ranks sixth. Although out of 1323 articles 683 (51.62 %) did not receive citations, 11 articles classified as excellent (0.83 %) obtained 24 % of 11,932 citations and, consequently, INCan normalized impact rate showed a mean productivity higher than the world mean. CONCLUSION: Multidimensional analysis with the proposed neural network enables obtaining a more reliable and comprehensive absolute and relative institutional scientiometric profile than that derived from measuring isolated variables.

BACKGROUND: Several performance metrics are commonly used by National Health Service (NHS) organizations to measure the efficiency and productivity of operating lists. These include: start time, utilization, cancellations, number of operations and gap time between operations. The authors describe reasons why these metrics are flawed, and use clinical evidence and mathematics to define a rational, balanced efficiency metric. METHODS: A narrative review of literature on the efficiency and productivity of elective NHS operating lists was undertaken. The aim was to rationalize how best to define and measure the efficiency of an operating list, and describe strategies to achieve it. RESULTS: There is now a wealth of literature on how optimally to measure the performance of elective surgical lists. Efficiency may be defined as the completion of all scheduled operations within the allocated time with no over- or under-runs. CONCLUSION: Achieving efficiency requires appropriate scheduling using specific procedure mean (or median) times and their associated variance (standard deviation or interquartile range) to calculate the probability they can be completed on time. The case mix may be adjusted to yield better time management. This review outlines common misconceptions applied to managing scheduled operating theatre lists and the challenges of measuring unscheduled operations in emergency settings.
ANTECEDENTES: Las organizaciones del National Health Service (NHS) suelen utilizar varias métricas de rendimiento para medir la eficiencia y la productividad de las listas quirúrgicas. Estas incluyen: hora de inicio, utilización, cancelaciones, número de operaciones, e intervalo de tiempo entre casos. Describimos las razones por las cuales estas métricas son defectuosas y nuestro objetivo es utilizar la evidencia clínica y las matemáticas para definir una métrica racional y equilibrada de eficiencia. MÉTODOS: Realizamos una revisión descriptiva de la literatura sobre la eficiencia y la productividad de las listas de cirugía electiva del NHS. Nuestro objetivo era racionalizar la mejor manera de definir y medir la eficiencia de una lista quirúrgica, y describir estrategias para lograrlo. RESULTADOS: Actualmente existe una gran cantidad de literatura sobre cómo medir de manera óptima el rendimiento de las listas quirúrgicas electivas. La eficiencia puede definirse completando todas las operaciones programadas dentro del tiempo asignado, sin excesos, ni infrautilización del tiempo. CONCLUSIÓN: Para lograr la eficiencia se requiere una programación adecuada utilizando la media (o mediana) de tiempo específica por caso y su varianza asociada (desviación estándar o rango intercuartílico) para calcular la probabilidad de que la programación se pueda completar a tiempo. Se puede ajustar el case mix para obtener una mejor gestión del tiempo. Esta revisión presenta conceptos erróneos frecuentemente aplicados a la gestión de listas de quirófanos programadas y los desafíos de medir operaciones urgentes no programadas.

OBJECTIVE: We developed a discrete event simulation model to evaluate the impact on system flow of a quality improvement (QI) initiative that included a time-specific protocol to decrease the time to antibiotic delivery for children with cancer and central venous catheters who present to a paediatric ED with fever. METHODS: The model was based on prospective observations and retrospective review of ED processes during the maintenance phase of the QI initiative between January 2016 and June 2017 in a large, urban, academic children's hospital in New York City, USA. We compared waiting time for full evaluation (WT) and length of stay (LOS) between a model with and a model without the protocol. We then gradually increased the proportion of patients receiving the protocol in the model and recorded changes in WT and LOS. RESULTS: We validated model outputs against administrative data from 2016, with no statistically significant differences in average WT or LOS for any emergency severity index (ESI). There were no statistically significant differences in these flow metrics between the model with and the model without the protocol. By increasing the proportion of total patients receiving this protocol, from 0.2% to 1.3%, the WT increased by 2.8 min (95% CI: 0.6 to 5.0) and 7.6 min (95% CI: 2.0 to 13.2) for ESI 2 and ESI 3 patients, respectively. This represents a 14.0% increase in WT for ESI 3 patients. CONCLUSIONS: Simulation modelling facilitated the testing of system effects for a time-specific protocol implemented in a large, urban, academic paediatric ED, showing no significant impact on patient flow. The model suggests system resilience, demonstrating no detrimental effect on WT until there is a 7-fold increase in the proportion of patients receiving the protocol.

Patient "no-shows" are missed appointments resulting in clinical inefficiencies, revenue loss, and discontinuity of care. Using secondary electronic health record (EHR) data, we used machine learning to predict patient no-shows in follow-up and new patient visits in pediatric ophthalmology and to evaluate features for importance. The best model, XGBoost, had an area under the receiver operating characteristics curve (AUC) score of 0.90 for predicting no-shows in follow-up visits. The key findings from this study are: (1) secondary use of EHR data can be used to build datasets for predictive modeling and successfully predict patient no-shows in pediatric ophthalmology, (2) models predicting no-shows for follow-up visits are more accurate than those for new patient visits, and (3) the performance of predictive models is more robust in predicting no-shows compared to individual important features. We hope these models will be used for more effective interventions to mitigate the impact ofpatient no-shows.

Most operating rooms around the world play music, both during the surgeries and in between cases. We investigated whether music tempo (fast or slow) can affect the operating room preparation time in between surgeries (turnover time) in an ambulatory outpatient surgical centre setting. We compiled two playlists, one with fast upbeat tempo and the other with slow relaxing tempo. Each of the playlists was played throughout the workday in the operating room for one week with the same surgeon and nursing staff. The turnover times for each case were analysed. Inclusion criteria were standard cataract extraction with intraocular lens implant surgery. Exclusion criteria were any external reasons causing delays in the turnover time (such as anaesthesia team break time, computer system down, etc.). The turnover time from 32 cases in the slow group and 26 cases in the fast group were compared with Student's t test. The turnover time was significantly faster in the fast group versus the slow group (17.0 ± 0.60 vs. 20.1 ± 0.96, p < 0.03). Our study demonstrated that fast music tempo in the operating room can significantly reduce turnover time. This improved efficiency could potentially lead to significant cost savings in the healthcare sector.

BACKGROUND: Surgery is a core activity in hospitals. Operating rooms have some of the most important and vital functions in medical centers. The operating rooms and their staff are a valuable infrastructure resource and their availability and preparedness affect human life and quality of care. OBJECTIVES: To prepare operational suggestions for improving operating room utilization by mapping current working processes in the operating rooms of a large private medical center. METHODS: Data on 23,585 surgeries performed at our medical center between August 2016 and March 2017 were analyzed by various parameters including utilization, capacity, working hours, and surgery delays. RESULTS: Average operating room utilization was 79%, while 21% was considered lost operating room time. The two major factors that influenced the lost operating room time were the time intervals between planned usage blocks and the partial utilization of operating room time. We calculated that each percent of utilized operating room time translates into 440 surgeries annually, resulting in a potential annual increase in income. CONCLUSIONS: Increasing operating room utilization would result in an improvement of operating room availability and an increased number of procedures. Our analysis shows that operating room utilization in the private healthcare system is efficient compared to the public healthcare system in Israel. Therefore the private healthcare system should be treated as a contributing factor to help lower surgery waiting times and release bottlenecks, rather than being perceived as contributing to inequality.

AIMS: The practice of alternating operating theatres has long been used to reduce surgeon idle time between cases. However, concerns have been raised as to the safety of this practice. We assessed the payments and outcomes of total knee arthroplasty (TKA) performed during overlapping and nonoverlapping days, also comparing the total number of the surgeon's cases and the total time spent in the operating theatre per day. MATERIALS AND METHODS: A retrospective analysis was performed on the Centers for Medicare & Medicaid Services (CMS) Limited Data Set (LDS) on all primary elective TKAs performed at the New England Baptist Hospital between January 2013 and June 2016. Using theatre records, episodes were categorized into days where a surgeon performed overlapping and nonoverlapping lists. Clinical outcomes, economic outcomes, and demographic factors were calculated. A regression model controlling for the patient-specific factors was used to compare groups. Total orthopaedic cases and aggregate time spent operating (time between skin incision and closure) were also compared. RESULTS: A total of 3633 TKAs were performed (1782 on nonoverlapping days; 1851 on overlapping days). There were no differences between the two groups for length of inpatient stay, payments, mortality, emergency room visits, or readmission during the 90-day postoperative period. The overlapping group had 0.74 fewer skilled nursing days (95% confidence interval (CI) -0.26 to -1.22; p < 0.01), and 0.66 more home health visits (95% CI 0.14 to 1.18; p = 0.01) than the nonoverlapping group. On overlapping days, surgeons performed more cases per day (5.01 vs 3.76; p < 0.001) and spent more time operating (484.55 minutes vs 357.17 minutes; p < 0.001) than on nonoverlapping days. CONCLUSION: The study shows that the practice of alternating operating theatres for TKA has no adverse effect on the clinical outcome or economic utilization variables measured. Furthermore, there is opportunity to increase productivity with alternating theatres as surgeons with overlapping cases perform more cases and spend more time operating per day.

Electronic health records are used widely across the nation in many different types of healthcare facilities. Electronic health record systems can provide more accurate and complete information about a patient's health, improve patient safety, and improve patient care. The purpose of this project is to evaluate a provider efficiency and workflow program at a hospital-owned, freestanding urgent care system after implementation of an electronic health record. A retrospective, longitudinal approach was used to evaluate the implementation of an electronic health record system among six freestanding urgent care clinics. The logic model was used as a guiding framework to determine whether provider efficiency and patient flow were improved. Data were collected from participants via an online survey, electronic health record data review, paper chart review, and direct observation of providers. An evaluation of a provider efficiency program using door-to-triage, door-to-provider, door-to-discharge, and average length of stay at each urgent care clinic was collected. The results indicate improvement in all areas after implementation of the electronic health record in all six urgent care settings. The average length of stay decreased from 109 minutes in 2014 to 73 minutes in 2016.
