The analysis finds comparing Time-Driven Activity-Based Costing, Duration Based Costing and Program Accounting Costing are analogous methodologies with different applications relating to timing cost recognition and are like comparing triples wearing the same but different colored outfits.

Malaria in the Republic of Guinea 2022-2023: costs associated with the care pathway from the patient's perspective.

Access to safe, financial affordable health care is a key factor in reducing health disparities. The malaria is a major public health issue, with significant economic implications in Guinea where the free malaria care services were introduced in 2010. This paper analyzes the costs associated with the care pathway for malaria patients in the Republic of Guinea. An analysis of the costs associated with malaria disease was conducted using data from a cross-sectional survey on the determinants of malaria care pathway between December 2022 and March 2023. The data were collected in health facilities and at community health workers. According to the patient's perspective, Time-Driven Activity-Based Costing (TDABC) and micro-costing approaches were used to assess the costs associated with care-seeking, cases management, and income loss. A total of 3300 patients were recruited in 60 health facilities. The majority were in urban areas (64.8%). One third of the patients were children under five years old. Over half of the patients or caregivers were without formal education, and most households were headed by husbands (78.5%). The median monthly income of the head of households was $116.0. Furthermore, after diagnosis, 25.5% of cases were uncomplicated malaria, 19.2% were complicated, and 52.2% were malaria associated with other diseases. Globally 41% of cases were on their first care pathway. The costs of care-seeking varied according to type of malaria, from $3.5 and $13.5 respectively for uncomplicated and complicated cases. The median direct costs of case management at health facilities were $7.3 (IQR: $4.1,13.3) for uncomplicated and $30.5 (IQR: 15.7, 51.4) for complicated cases. The total costs associated with the global care pathway differed across types of malaria and age groups, with median costs estimated at $17.4 (IQR: 6.7, 34.8) for uncomplicated cases and $43.5 (IQR: $ 19.7, 74.0) for complicated malaria. A delay in appropriate care-seeking accounted for 19% of the costs incurred by malaria patients in Guinea (p < 0.001). Despite the introduction of free malaria prevention services, malaria patients or their caregivers continue to incur costs and loss of income. An approach to selective, free and affordable flat-rate costs could ensure the financial viability of health facilities and reduce out-of-pocket expenses. The next research will focus on the impact of free selective and flat-rate pricing on out-of-pocket expenses, and the analysis of the perception of the malaria care services by care providers and users.

Does Transforaminal Endoscopic Lumbar Discectomy Provide More Value than Microdiscectomy? An Application of the Operative Value Index

BACKGROUND AND OBJECTIVES: A few studies have compared the value (outcomes per dollar spent) provided by transforaminal endoscopic discectomy (TED) vs microdiscectomy (MD) for lumbar disc herniations. Here, we attempt to address this gap using a novel Operative Value Index (OVI), which combines a procedure-specific patient-reported outcome with intraoperative cost data based on time-driven activity-based costing. METHODS: MD (n = 95) and TED (n = 23) performed by neurosurgeons at our institution from 2017 to 2022 were retrospectively identified. Time-driven activity-based costing was applied to identify both direct and indirect costs for all cases. Individual costs were obtained by direct observation, electronic medical records, and through consulting multiple departments (including business operations, sterile processing, plant operations, and pharmacy). Oswestry Disability Index (ODI) scores were prospectively collected at baseline and 3 months after surgery. Our primary outcome of interest was the OVI, defined as the percent change in the ODI per $1000 spent intraoperatively. Generalized linear mixed model regression was performed to assess whether TED was associated with significantly different OVI as compared to MD. Similar analyses were also performed for operative times and length of stay. RESULTS: The average intraoperative cost of a TED was $3698, as compared to $3410 for an MD. For both procedures, this total cost was largely driven by the cost of supplies and personnel. Multivariable regression revealed that MD was associated with significantly higher OVI (β-coefficient: 7.2, P &lt; .05) and lower operative times (β-coefficient: - 34.6 minutes, P &lt; .01) compared with TED, with no significant differences in length of stay (P = .17). CONCLUSION: When performed by surgeons at our institution from 2017 to 2022, MD was associated with a 7% greater improvement in ODI per $1000 spent intraoperatively. Continual assessment of value over time (both for established procedures and new techniques) will become increasingly important with the emergence of value-based care.

Inpatient cost comparison of total and unicompartmental knee arthroplasty in patients with medial compartmental osteoarthritis using time-driven activity-based costing.

Using time-driven activity-based costing (TDABC), we sought to compare the total facility costs, comprising supply and personnel costs during the episode of care for the index procedure, in patients with isolated medial compartmental knee osteoarthritis (OA) undergoing unicompartmental knee arthroplasty (UKA) versus total knee arthroplasty (TKA). We conducted a retrospective analysis of 100 UKAs and 100 TKAs from 2019 to 2022. From a larger sample of 4899 TKAs and 137 UKAs, patients with isolated medial OA (Kellgren-Lawrence Grade <2 in other compartments) were radiographically identified. Demographic data included age, sex and body mass index, with comorbidities controlled using the Charlson comorbidity index. Facility costs were calculated using TDABC and standardized in cost units (CUs), a metric for comparing costs across procedures. Multiple regression analysis was used to assess the independent effect of TKA versus UKA on facility costs. TKA patients had similar operative times (TKA vs. UKA: 1.01×, p = 0.783) and supply costs (1.00×, p = 0.866), where 'x' denotes the relative cost ratio. However, TKA was associated with higher personnel costs (260.0 vs. 222.5 CUs [1.17×], p < 0.001) and total facility costs, both including (706.3 vs. 667.5 CUs [1.06×], p = 0.007) and excluding implants (353.8 vs. 312.5 CUs [1.13×], p < 0.001). Adjusted for demographics and comorbidities, TKA had increased facility costs, including (32.2 CUs, 95% confidence interval [CI]: 2.9-61.5, p = 0.031) and excluding implants (37.8 CUs, 95% CI: 15.2-60.3, p = 0.001). TDABC analysis revealed higher total facility costs for the index procedure in TKA, suggesting UKA may be a cost-saving alternative for isolated medial compartment knee OA. Level III, retrospective comparative study.

Abstract 4143262: Unlocking Value: Revealing the Hidden Cost of Outpatient Interstage Care

Background: Interstage programs decrease morbidity and mortality and are potentially resource intensive. The accurate cost of these programs is unknown. Understanding cost and outcomes of care is necessary to provide high-value care for this population. Time-driven activity-based costing(TDABC) provides an accurate way to understanding costs that occur at the level of the patient. Research Question: What is the outpatient cost of the interstage period to the health care system? Methods: Single-center study of outpatient interstage care. Direct observation (over 9 months) and retrospective review were utilized to develop process maps. Outpatient interstage and pediatric visits were timed by 5 observers. Cost of personnel was calculated in dollars per minute utilizing median national health system salary data. Results: Patients attended a median of 13 cardiology, 5 pediatric, 3 physical therapy(PT), 4 occupational therapy(OT), and 7 speech therapy(SLP) visits while interstage. Total cost of interstage visit personnel was $258.18[$208.59-$389.24] and equipment cost was $1457.79. Total cost of a pediatric visit was $123.55[$130.80-$167.12]. Total cost of outpatient PT, OT, and SLP was $70.58, $66.68 and $72.43, respectively. Total cost of the outpatient interstage period was $6417.38[$5808.94-$8338.96] per patient.(Table) In interstage clinic, patients spent 132[89-165] minutes with providers and 64[41-66] minutes waiting.(Figure) In pediatric clinic, patients spent 73[71-76] minutes with providers and 9[6-13] minutes waiting. Conclusion: This work demonstrates that while challenging, TDABC analysis can be applied to complex interstage care to understand costs and move to deliver high-value care for this population. While caring for a child during the interstage period is time and resource intensive, it carries a relatively low cost to the health care system with a total cost of $6417.38 per patient. Additional work is needed to understand costs of inpatient interstage care.

Assessing the long-term care (LTC) service needs of older adults based on time-driven activity-based costing (TDABC)–a cross-sectional survey in central China

BackgroundThe global population’s aging has led to an increasing demand for long-term care (LTC), especially in developing countries like China. Comprehensive assessment of LTC service demands by including the time and cost analysis is crucial to inform the planning and financing of LTC resources, yet such research is lacking in China. Our research team has developed a quantitative index system of the medical and nursing services needs of older adults (QISMNSNE) based on the framework of Time-Driven Activity-Based Costing (TDABC), providing a valuable tool for measuring LTC service needs. This study aimed to assess the LTC service needs of older adults in China and the factors associated with such needs.MethodsA cross-sectional study was conducted in Changsha City, Hunan Province, China, from June 2021 to December 2022. A stratified multistage cluster sampling method was used to recruit 1,270 older adults from five nursing homes and three communities/streets in three regions of Changsha City. The LTC service needs were assessed by calculating the service time required from caregivers, nurses, and doctors and the total service time (min/d) using the QISMNSNE. Participants’ disability, activities of daily living (ADLs), mental status and social involvement (MSSI), and sensory and communication (SC) were assessed using standard scales. Generalized linear regression models were used to analyze factors associated with LTC service needs.ResultsThe participants had an average age of 76.41 ± 8.38 years, with 43.7% being female. The median service time required from caregivers, nurses, and doctors was 53.34 min/d, 3.66 min/d, and 0.33 min/d, respectively, and the total service time was 83.31 min/d. The generalized linear regression model identified the following factors that were associated with higher total service time: aged 75–84 years, living in nursing homes, income over 5000 per month, ADLs, MSSI (9 ~ 40), SC, and having 3 ~ 4 kinds of geriatric comorbidity (P < 0.05).ConclusionsOlder adults have a high need for LTC services, especially those provided by caregivers, indicating an urgent need to expand and improve LTC systems. The LTC service time needed is associated with multilevel factors encompassing socio-demographic, functional, and psychological aspects. This study offers preliminary insights into the needs, demands, and costs of LTC services for older adults and provides essential guidance for future planning and financing of LTC resources.

What is the True Cost of Motion Preservation? A Time-Driven Activity-Based Cost Analysis of Anterior Cervical Discectomy and Fusion versus Disc Replacement

Total disc replacement (TDR) has become a viable alternative to anterior cervical discectomy and fusion (ACDF) for select patients. Although most comparative studies have assessed outcomes, cost differences remain largely uninvestigated. This information is critical as we move towards value-based reimbursement. To address this knowledge gap, we used time-driven activity-based costing (TDABC) to compare total intraoperative costs between the two procedures. Total cost was divided into direct (personnel and supply cost) and indirect costs (administrative and overhead costs). Individual costs were determined through direct observation, electronic medical records, and through querying multiple departments (including business operations, sterile processing, plant operations, and pharmacy). Timestamps for all involved personnel and material resources were documented, in conjunction with process mapping of the intraoperative period. Total intraoperative costs were estimated for all ACDFs (n=810) and TDRs (n=54) from 2017 to 2022. Regression analyses were performed to identify factors associated with total cost. A total of 810 and 54 patients underwent one- and two-level ACDFs and TDRs, respectively. The average total intraoperative cost for an ACDF was $6,776 +/- $2,808, compared to $12,026 +/- $4,235 for TDR. Supply cost accounted for the majority of total cost for both procedures ($4,173 +/- $2,225 for ACDF and $9,532 +/- $4,010 for TDR). On multivariable linear regression analysis, TDR was associated with roughly $3,885 of additional cost compared to ACDF (p<0.001), as well as $4,072 in additional supply cost (p<0.001), most of which was driven by the higher cost of implants (p<0.001). TDABC is a highly useful methodology for estimating differences in true costs between procedures and determining cost drivers. TDRs were associated with an additional $3,885 of total intraoperative cost as compared to ACDFs, the majority of which was driven by the cost of implants.

Cost estimation of preventive dental hygiene care using Time-Driven Activity-Based Costing (TDABC)

Objectives: This study used Time-Driven Activity-Based Costing (TDABC) to measure the value of preventive dental hygiene care and offering a more practical and adaptable cost management method than compared to traditional cost accounting approaches.. Methods: A descriptive survey was conducted using 164 questionnaires collected from dental hygienists actively involved in preventive dental care. The cost data related to labor, materials, and overheads, were anlyzed using detailed classifications of procedures such as scaling, fluoride application, and sealant application. Results: The total allocated cost of 10,163,355 South Korean Won (KRW) was divided by the total working time of the dental clinic (23,520 min), providing a unit cost of 432 KRW/min. Among the three preventive dental care procedures, scaling had the highest total activity cost of 5,867,243 KRW. Conclusions: This study provides valuable evidence for the implementation of an appropriate fee system for preventive dental care performed by dental hygienists. Therefore, this study contributes to the establishment of a fair and rational reimbursement structure.

Penentuan tarif sewa kamar kost melalui perhitungan harga pokok kamar menggunakan metode activity based costing (Studi kasus Eben Kost Manado)

Achieving maximum profit is closely tied to specific calculations regarding the costs incurred to produce a service product, such as the cost of a room. Activity-Based Costing (ABC) is one method used to calculate the cost of a room by evaluating expenses based on the resources consumed by various activities. The objective of this research is to determine room rental rates by calculating the cost of a room using the Activity-Based Costing method at Eben Kost Manado. The research employed a qualitative descriptive approach. Data collection techniques included interviews and documentation. The findings indicate that the room rental rates determined using the Activity-Based Costing method are lower compared to those set by Eben Kost because the ABC method allocates all activity costs to each room type precisely based on each activity's consumption.

Enhancing financial management in healthcare: The impact of Activity-Based Costing and Time-Driven Activity-Based Costing methodologies in Kordan's private sector in Jordan

This study examines the effectiveness of implementing Activity-Based Costing (ABC) and Time-Driven Activity-Based Costing (TDABC) in Jordan’s private healthcare sector focusing on managing costs while maintaining quality care. A descriptive and analytical approach was adopted involving 213 individuals working in the financial affairs departments of private hospitals in Amman representing various types of institutions. The key variables of interest were the accuracy of cost measurement, expense reduction, cost allocation and various cost management approaches. The main findings indicate that implementing ABC and TDABC significantly improved cost management and cost reduction within these institutions. These systems have been effective in enhancing the accuracy of cost measurement, improving profitability, reducing unnecessary expenses, and achieving better cost allocation, thereby leading to better financial stewardship. This study underscores the critical importance of integrating these systems into healthcare financial frameworks. Moreover, it highlights the need for further training for financial managers and accountants to fully leverage these approaches and contribute to ongoing improvements in healthcare financial management. Additionally, this research presents empirical evidence from an underrepresented region where no prior studies have been conducted, thereby contributing to the existing body of knowledge and offering valuable insights for future initiatives in Jordan. The study also provides useful guidance for implementing these cost-management approaches more broadly in other regions and countries.

Do vaginal swabs alter empirical clinical management in obstetrics and gynaecology: A retrospective case-series and activity-based costing of the vaginal swab.

Vaginal swab microbiological testing is commonly performed as routine clinical management for various obstetric and gynaecological presentations. The clinical utility and cost-effectiveness of vaginal swab microscopy, culture and susceptibilities (MCS) in altering empirical management is ill-defined. To describe the clinical use of vaginal swabs in a tertiary women's hospital emergency department (ED), measure the impact of vaginal swabs on altering empirical clinical management, and to determine the economic cost of vaginal swab MCS. Retrospective case-series of vaginal swabs collected at a single, tertiary women's ED between January 2021 and July 2021. Symptomatology, clinical diagnosis, test results, and pre-swab and post-swab clinical management were determined upon medical record review. Economic costs of vaginal swab MCS were retrospectively determined via internal accounting records, permitting unit-level activity-based costing. A total of 660 vaginal swabs from 584 clinical episodes were included. Vulvovaginitis was the most common indication for swab collection (34.5%, 167 samples). Altered empirical management was observed in 9.8% of all swabs (95% CI 7.4-12.2%), with marked variability between clinical indications. Antimicrobial initiation was the most common alteration in management (8.9%, 95% CI 8.7-9.1%). The estimated cost of vaginal swab MCS was $29.71 AUD; labour, consumables and disposal costs accounted for 69.3, 29.8 and 0.9%, respectively. The impact of vaginal swab MCS on empirical clinical management is context-specific and variable. The majority of swabs performed do not impact upon empirical management. Antimicrobial initiation is appreciably more common than antimicrobial cessation with vaginal swab results.

Integrating Activity-based Costing with Continuous Enhancement: A Strategic Approach to Operational Efficiency and Cost Management

The main objective of this research is to show how integrating activity-based costing (ABC) with continuous improvement processes can enhance cost management and operational efficiency. The development of automated firms and global firms has necessitated a shift in principles and measurement accuracy. The principles and concepts have been modified based on economic theory, moving from stable continuous improvement to continuous enhancement, or Kaizen enhancement. The accuracy of the proposed costing system has improved by using modified activity-based costing. The current research has focused on multi-variation in explanatory variables, including the costing system and the degree of enhancement. The suggested costing system should include the modified version of activity-based costing and the new form of continuous enhancement system. The concept of an intelligent supply chain has led to the idea of a cooperative game between all parties in the firm/chain. Intelligent automated systems are closed-loop systems where all members are partners, aiming to maximize global benefits. Resilient considerations indicate different attempts to measure and estimate the multi-effects of externalities and other external effects. This work has closed-to-open excess quantitative models, achieving the cooperative state between different partners. Findings show that ABC helps manufacturing and service sectors identify non-value-adding activities, optimize resource allocation, and reduce costs by providing detailed insights into the true cost of operations. Its integration with continuous improvement strategies amplifies these benefits, enabling businesses to streamline processes, improve efficiency, and enhance profitability. ABC is a valuable tool for identifying non-value-adding activities and optimizing resource allocation. By providing a more accurate understanding of how resources are consumed, ABC can help organizations improve their efficiency, reduce costs, and enhance customer satisfaction.

Revolutionizing Textile Manufacturing: Sustainable and Profitable Production by Integrating Industry 4.0, Activity-Based Costing, and the Theory of Constraints

The textile industry, a cornerstone of daily life and a highly globalized sector, faces significant environmental challenges due to its high water and energy consumption and extensive chemical usage. This study proposes a comprehensive green production planning and control model integrating Industry 4.0 concepts, activity-based costing (ABC), and the theory of constraints (TOC). The model utilizes mathematical programming to optimize product mix, maximize profitability, and minimize environmental impact. It leverages real-time sensing technologies and ERP systems to facilitate waste recovery, reduce carbon emissions, and achieve energy savings. Various carbon emission cost models, including continuous and discontinuous tax functions, are explored to balance corporate profitability with environmental sustainability. The findings demonstrate the model’s potential in optimizing resource utilization, reducing the environmental footprint, and enhancing profitability.

Patient-Level Value Analysis in Total Hip Arthroplasty: Optimizing the Value of Care Delivery

Background: Value is defined as the ratio of patient outcomes to the cost of care. One method to assess value is through patient-level value analysis (PLVA). To our knowledge, this tool has not previously been implemented in the setting of total hip arthroplasty (THA). The purposes of this study were to perform PLVA for a 1-year episode of care among patients undergoing primary THA and to identify characteristics that affect value in a metropolitan health-care system. Methods: The patient-reported outcome (PRO) measure database of the institution was queried for all primary THAs from 2018 to 2019. The PRO measure that was utilized was the Hip disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS-JR). Cost was evaluated with use of time-driven activity-based costing (TDABC) for a 1-year episode of care (consisting of the day of surgery, inpatient stay, discharge facility, postoperative appointments, and physical therapy). The primary outcome was the 1-year value quotient, or the ratio of the 1-year change in HOOS-JR to the cost of the episode of care (VHOOS). The value quotient was compared among all included patients and evaluated for variables that may affect the overall value of the episode of care. Results: In total, 480 patients were included in the analysis. The mean improvement in the HOOS-JR was +34.9 ± 16.1 (95% confidence interval [CI]: 33.5, 36.3). The mean cost was $13,835 ± $3,471 (95% CI: $13,524, $14,146). The largest contributor to cost was implants (39.0%), followed by post-recovery care (i.e., inpatient stay and specialized nursing facilities; 24.1%). Change in the HOOS-JR was poorly correlated with the cost of care (r = −0.06; p = 0.19). THAs performed at an ambulatory surgery center (ASC) with discharge to home demonstrated higher value (VHOOS = 0.42) than THAs performed at a hospital with discharge to a rehabilitation facility (VHOOS = 0.15; analysis of variance F-test, p &lt; 0.01). Conclusions: Our study found that PROs did not correlate with costs in the setting of primary THA. Implants were the largest cost driver. Surgical setting (an ASC versus a hospital) and discharge destination influenced value as well. PLVA is a value measurement tool that can be utilized to optimize components of the care delivery pathway. Level of Evidence: Therapeutic Level III.

Time-Driven, Activity-Based Cost Analysis of Pars Plana Vitrectomy in Rhegmatogenous Retinal Detachment at a Large Academic Center.

Purpose: To perform a time-driven, activity-based cost analysis of retinal detachment (RD) surgery and compare it with reimbursement rates. Methods: This economic analysis at a single academic institution used time-driven, activity-based costing methodology to determine the cost of rhegmatogenous RD repair with primary pars plana vitrectomy. A process flow map was created to highlight each surgical case's operative episodes, including clinical follow-ups. Time logs were obtained from the electronic health record for each operative phase and clinical follow-up. The overhead and anesthesia costs were collected from the institution's cost accounting system. The direct material and personnel costs were obtained from internal financial data. Results: Seventy-six cases that met the inclusion criteria were included in the cost analysis study. The time-driven, activity-based cost of RD was $6247.17, and the reimbursement was $5442.91. Therefore, each procedure had a net negative loss of $804.26. To break even, the average operation time would need to be reduced from the determined average of 90.49 minutes to 64.90 minutes. Conclusions: This study found that Medicare underestimates the true cost of RD surgery. Changes in referral patterns may be motivated by reimbursement rates lower than the cost of the procedure, which could ultimately affect patient access to care.

Cost Drivers of Pars Plana Vitrectomy for Retinal Detachment: Time-Driven Activity-Based Costing Analysis.

Introduction: To determine drivers of day-of-surgery costs for pars plana vitrectomy (PPV) in the management of retinal detachment (RD) repair, the mainstay treatment, based on surgical complexity and intraoperative factors. Methods: Economic analysis was performed using time-driven activity-based costing methodology for patients who had standard (Current Procedural Terminology [CPT] code 67108) or complex (CPT 67113) RD repair with PPV at the University of Michigan in 2021. Data were obtained via the electronic health record and previous literature. PPV expenses were determined with time-driven activity-based costing, a cost calculation that incorporates time and key resource costs, and were analyzed using univariate and multivariate regression. Results: The analysis included 412 PPVs (270 standard and 142 complex based on CPT code). The operating room time was significantly increased in complex cases (P < .01). Univariate analysis found that complex PPV, cryopexy, staining agent use, retinectomy, simultaneous scleral buckling, perfluoro-N-octane (PFO) use, silicone oil tamponade, and perfluoropropane tamponade were associated with a statistically significant difference in costs (P < .01); use of laser retinopexy was not significantly associated (P = .7190). Multivariate analysis found that standard PPV cost an average $5132.33 and significant incremental costs were found for complex PPV (+$1185.55; P < .001), cryopexy (+$465.02; P = .032), staining (+$525.16; P = .04), PFO use (+$1089.54; P < .0001), retinectomy (+$2031.17; P < .0001), and simultaneous scleral buckling (+$916.34; P = .006). Conclusions: The intraoperative factors that increase operating room time and ultimately the incurred cost of complex PPV cases vs standard PPV were identified and economically defined. These findings can improve practice patterns by optimizing costs for effective surgical planning in the management of RD repair.

Estimation of two-year hospital costs of hip and knee periprosthetic joint infection treatments using activity-based costing.

Our aim was to estimate the total costs of all hospitalizations for treating periprosthetic joint infection (PJI) by main management strategy within 24 months post-diagnosis using activity-based costing. Additionally, we investigated the influence of individual PJI treatment pathways on hospital costs within the first 24 months. Using admission and procedure data from a prospective observational cohort in Australia and New Zealand, Australian Refined Diagnosis Related Groups were assigned to each admitted patient episode of care for activity-based costing estimates of 273 hip PJI patients and 377 knee PJI patients. Costs were aggregated at 24 months post-diagnosis, and are presented in Australian dollars. The mean cost per hip and knee PJI patient was $64,585 (SD $53,550). Single-stage revision mean costs were $67,029 (SD $47,116) and $80,063 (SD $42,438) for hip and knee, respectively. Two-stage revision costs were $113,226 (SD $66,724) and $122,425 (SD $60,874) for hip and knee, respectively. Debridement, antibiotics, and implant retention in hips and knees mean costs were $53,537 (SD$ 39,342) and $48,463 (SD $33,179), respectively. Suppressive antibiotic therapy without surgical management mean costs were $20,296 (SD $8,875) for hip patients and $16,481 (SD $6,712) for knee patients. Hip patients had 16 different treatment pathways and knee patients had 18 treatment pathways. Additional treatment, episodes of care, and length of stay contributed to substantially increased costs up to a maximum of $369,948. Treating PJI incurs a substantial cost burden, which is substantially influenced by management strategy. With an annual PJI incidence of 3,900, the cost burden would be in excess of $250 million to the Australian healthcare system. Treatment pathways with additional surgery, more episodes of care, and a longer length of stay substantially increase the associated hospital costs. Prospectively monitoring individual patient treatment pathways beyond initial management is important when quantifying PJI treatment cost. Our study highlights the importance of optimizing initial surgical treatment, and informs treating hospitals of the resources required to provide care for PJI patients.

Averting bankruptcies among the software development houses in Lahore, Pakistan

Pakistan, as the 4th largest technological market globally, is home to over 2000 registered software development houses. However, the industry is not without its challenges, and hundreds of these houses close yearly owing to insolvency, and even more crop up. To understand the financial difficulties these houses face, a sample of 20 small-size and 20 medium-sized software houses has been taken from the hundreds in Arfa Software Technology Park in Lahore, Pakistan. Financial Blueprints of 2 projects per house per year for five years, i.e., 2018-2022, have been obtained. These case studies have been contrasted with those written and published in the developed world. It is found that there is a dearth of costing and pricing mechanisms in software-related projects. This results in under/over-costing the cost and pricing of the projects, which is a leading cause of financial bankruptcy for most software houses. It is proposed that activity-based costing, as the costing technique, and competitive pricing, as the pricing mechanism, may be adopted as the best practice in the software development industry. These solutions, if implemented, could significantly reduce the risk of financial bankruptcy among software houses, potentially transforming the industry's financial landscape.
