Most of important variables measured in medicine are in numerical forms or continuous in nature. New
instruments and tests are constantly being developed for the purpose of measuring various variables, with the aim
of providing cheaper, non-invasive, more convenient and safe methods. When a new method of measurement
or instrument is invented, the quality of the instrument has to be assessed. Agreement and reliability are both
important parameters in determining the quality of an instrument. This article will discuss some issues related
to methods comparison study in medicine for the benefit of medical professional and researcher.
METHOD:
This is a narrative review and this article review the most common statistical methods used to assess agreement
and reliability of medical instruments that measure the same continuous outcome. The two methods discussed
in detail were the Bland-Altman Limits of Agreement, and Intra-class Correlation Coefficient (ICC). This article
also discussed some issues related to method comparison studies including the application of inappropriate
statistical methods, multiple statistical methods, and the strengths and weaknesses of each method. The
importance of appropriate statistical method in the analysis of agreement and reliability in medicine is also
highlighted in this article.
CONCLUSION:
There is no single perfect method to assess agreement and reliability; however researchers should be aware
of the inappropriate methods that they should avoid when analysing data in method comparison studies.
Inappropriate analysis will lead to invalid conclusions and thus validated instrument might not be accurate
or reliable. Consequently this will affect the quality of care given to a patient.

Objective. This pilot study aimed to determine the epidemiologic burden of hospitalization for bronchial asthma in acute exacerbation.
Methods. We used a descriptive cross-sectional study to describe the demographic profile, comorbidities and level of control of patients admitted for bronchial asthma in acute exacerbation admitted to the Philippine General Hospital from May 1 to October 31 2019. The study computed for the admission rate and compared the average cost of hospitalization (diagnostics, therapeutics and room) using direct costing to the total reimbursable cost from PhilHealth. Associations between patient characteristics (age, type of admission) and hospitalization cost were also determined.
Results. We enrolled 45 patients in the study. The admission rate was 8/month. The mean cost of admission was significantly higher than the reimbursable amount from PhilHealth (Php 20,074.63 versus Php 9000) (p = 0.004). Cost of hospitalization was significantly higher in pay patients versus charity (p = 0.001 for diagnostics, p = 0.005 for treatment and p = 0.001 for room cost), in patients with poorly controlled asthma (p = 0.020 for diagnostics and p = 0.014 for room cost) and those with frequent short-acting beta-agonist (SABA) use (p = 0.001).
Conclusion. Asthma remains an economic burden for the Filipino patient. Persistent SABA use, perceived asthma control of patients and increased expenses associated with an asthma exacerbation admission lead to significant out-of-pocket expenditure.

The purpose of this research is to suggest a model for hospital process and verily the model through analyzing the results before and after reengineering grounded on the activity -based costing. The summary of research is as follows: First, two reengineering-applicable processes for a case hospital are chosen based on the issues from the patient requirements analysis and current process analysis as well as the general characteristics of hospital operations: accounting and clinical laboratory e xami nation processes. The integration of payment-related functions principle is applied to an accounting process which includes three sub processes. while the automatic transition of laboratory output principle is applied to a clinical laboratory examination process. Second, the studs shows more than 50% reduction of activities: nine activities from nineteen by the principle of integration of payment-related functions, and nine activities from fourteen by the principle of automatic transition of laboratory output. Finally. activity-based cost analysis before and alter reengineering results in 44% cost reduction: 43.9% in payment-related subprocesses and 41.1% in a clinical laboratory examination process. Therefor this research finds an enormous gap between costs before and after reengineerring. The contributions of this research are two-fold: one is that activity-based costing methodology is practically valid for measuring the cost-performance analysis of hospital process reengineering, and another is that activity -based costing can he utilized not only an initiative of process engineering hut also as a tool for evaluating a variety of activities by a simulation technique.

Acta Medica Philippina 2024;58(10):65-73
Objectives:
This study aims to analyze the cost of patient care among ORL-HNS patients admitted in a tertiary, teaching government hospital in a low- to middle-income country.
Methods:
This is a prevalence-based, prospective, bottom-up, cost-of-illness analysis among patients of the Department of Otorhinolaryngology-Head and Neck Surgery in a tertiary training government hospital admitted from July 2021 to March 2022. The value assessment method used is the human capital approach. The societal perspective is used for analysis to estimate and reflect payer (insurance providers) and patient perspectives.
Results:
A total of one hundred fifty seven (157) patients were admitted for elective surgery under the service of ORL-HNS consisting of 75 females and 82 males. The average total overall cost was $3,851.10 (Php 199, 870.50 ± 164, 725.60). The total direct health care cost for all patients within the study period amounted to $3,712.18 (Php 192, 662.22 ± 159, 548.60) while the direct non-health care cost was $58.60. The workforce cost (58.5%) and medication cost (18.8%) comprised the majority of in-patient expenses with a mean cost of $2,221.36 (Php 37,083.66) and $714.51 (Php 44,363.14), respectively. In this study, an average of $80.29 was lost due to illness and hospitalization (± $81.74). The total PHIC coverage pays a range from zero to 67.5% with an average coverage of only 17%.
Conclusion
Our analysis has shown that workforce and medication expenses are the main cost drivers for the direct healthcare costs among Otolaryngology patients admitted for elective procedures. Stakeholders, such as the otolaryngologists and hospitals should coordinate closely to create a more encompassing coverage of Philhealth to prevent patients from suffering from financial crises due to their illness.

BACKGROUND: Schistosomiasis is endemic in the Philippines. Currently, the financial and economic costs of hospitalization due to schistosomiasis have not been studied or analyzed. This will be essential to the review of health benefit package of PhilHealth for schistosomiasis.
OBJECTIVES: This study estimated the cost of hospitalization due to schistosomiasis and its complications in the Philippines.
METHODS: This is a cross-sectional mixed-methods study. Nine (9) hospitals from schistosomiasis-endemic provinces were included in the study. Medical records and billing statements from year 2013 were retrieved and analyzed. Non-medical costs were calculated based on data from key informants and existing economic data in 2013.
RESULTS: A total of 1,415 hospitalized cases were collected; 94% came from government hospitals. Fifty nine percent (59%) were classified under uncomplicated schistosomiasis. Overall hospitalization costs were PhP 8,489,524.39 (USD 200,006.70), with cases of hepatic complications having the highest costs among all types of cases. Combined nonmedical costs and productivity losses for 5,005 days of hospitalization were PhP 13,019,363.75 (USD 306,726.25).
CONCLUSION: The estimated clinical cost burden and economic losses due to schistosomiasis in selected sites in the Philippines amount to PhP 21,508,888.14 (USD 506,732.95). Significant drivers of cost were the presence of schistosomiasis sequelae or complications, co-morbidities, and increasing length of stay. Estimated productivity losses and non-medical expenses of patients due to hospitalization were found to be more burdensome than the actual hospital bills. These costs stress the need for government to provide health coverage for patients diagnosed with schistosomiasis.

Objective:
This paper aims to provide a better understanding of the different engagement, cost, and resource
considerations in developing and implementing mHealth solutions in the Philippines during the COVID-19 pandemic.
Methods:
First, six participants completed a form to document the estimated costs of developing a pseudo mobile application with features to mitigate the pandemic. Second, ten key informant interviews determined the facilitators, barriers, and resource requirements in developing mHealth tools.
Results:
The average cost estimate to develop and roll out a mobile application with public health and epidemiology features is Php 4,018,907 (US $78,650). The analysis of the interviews resulted in 12 themes organized in three domains: 1) facilitators and barriers in developing and sustaining mHealth solutions; 2) costs of sustaining mHealth technologies; and 3) factors affecting the costs of development and maintenance of mHealth technologies.
Conclusion
While differences in the cost estimates are evident, it provides a ballpark figure and the different factors that implementers need to sustain and maintain an mHealth solution. This paper hopes to inform policies and practices in engaging technology solution partners and in scaling up mHealth technologies.

Hospitals are experiencing an increasing amount of financial difficulty due to government control of hospital rates since national health insurance has been implemented. The decision support system(DSS) was developed to provide cost and revenue information for the services rendered by each department in an effect to reduce costs. This information may be used to identify the causes of financial loss if cost exceeds revenue and to conduct variance analysis or portfolio analysis to improve financial situation of hospitals. The DSS was developed using a micro-mainframe interface approach where the mainframe computer collects and summarizes daily cost and revenue data and the micro computer computes the cost for each department. The significances of this paper are to determine the cost allocation basis and methods which are suitable to Korean situation and to apply DSS technology to the cost analysis.

Journal of Korean Academy of Nursing Administration 2017;23(2):139-150
PURPOSE: The purpose of this study was to identify nursing service costs associated with all health care costs incurred by the institution. METHODS: This study was an empirical case study research in which the nursing cost was separated from total medical cost. The nursing cost index was calculated through a cost allocation method after summarizing costs for personnel, raw materials and administration of each department in one public hospital. The 2014 budget plan, published in ‘Public Hospitals Alert’, was used as data and the data were analyzed using the Microsoft Office EXCEL 2013 program. RESULTS: When comparing total medical costs and nursing costs, the nursing cost were 27.14% of the total medical cost. The nursing cost per nurse per hour was calculated as ₩29,128 The nursing cost per inpatient per day was calculated as ₩157,970, and the administration cost per patient was calculated as ₩133,710. CONCLUSION: The results of the research present the process of cost allocation of specific cost elements in the hospital and evidence for administrative costs which in the past have been only vaguely formulated. These are the significant implications of this study.

The purpose of this study was to investigate the operational characteristics of the contract-managed highschool foodservice and to analyze the factors to effect the menu price. The data was collected from 249 highschools in Seoul. The results are as follows; Those surveyed highschools were established as 1 national, 74 public, and 174 private institution. Highschools were classified as 176 academic, 66 vocational, and 7 specific purposed institution. Students were organized as 70 boys', 23 girls', and 41 coeducational highschools. Most highschool started contract-managed highschool foodservice from 1999 and the period of foodservice contract was most 3 years and the operation styles in food distribution were 96 classrooms, 105 dining halls and 17 classrooms combined dining halls. The scale of contract foodservice management companies was 63.1% small and medium and 36.9% large enterprises. The surveyed highschools had the average meal price 2,141 won per meal and they had 1,518 pupils on the register. The participating rate to the foodservice was 68.5%. The facilities investment cost of the contract foodservice management company was 179,204,230 won for private institutions and was 138,119,010 won for national&public institutions. The period of the contract was 3.22 years in private institutions, which was significantly higher than national&public institutions which showed 2.85 years. The commissary foodservice schools had higher facilities investment cost than conventional foodservice schools. Classrooms foodservice had higher participating foodservice rate than Dining halls. The investment cost for facilities showed high in order of girls', boys', and coeducational high schools, and the number on the register and the number participating in the foodservice showed high in order of boys', girls', and coeducational high schools. The number on the register showed the highest in academic and vocational schools, specific purposed institutions in sequence, and the number participating in the foodservice showed high in order of academic schools, specific purposed institutions and vocational. However, the participating foodservice rate showed high in specific purposed institution, academic and vocational schools in order, and the meal price, the investment cost for facilities showed high in specific purposed institution, academic and vocational schools in sequence. Regionally, the district south of Han river had the average meal price 2,266.13 won, which showed higher in the eastern part which had 2,033.33 won. The western part had the average investment cost for facilities of 233,331,060 won, and the central district 126,137,140 won. The number on the register showed 1845.68 in the eastern part and 1308.00 in Dong-Jak area, that had clear differences among areas. When the period of the contract went longer, the investment cost for facilities had a tendency to increase. The significant differences were existed among meal price, the investment cost for facilities, the number on the register, the number participating in the foodservice, and the participating foodservice rate. The investment cost for facilities had increased according to the number participating in the foodservice and the participating foodservice rate. And the large enterprises showed higher participating foodservice rate than the small and medium enterprises.

BACKGROUND/AIMS: It is believed that disposable biopsy forceps are more costly than reusable biopsy forceps. In this study, we evaluated performance and cost of disposable forceps versus reusable forceps in esophagogastroduodenoscopic biopsy. METHODS: Between October 2009 and July 2010, we enrolled 200 patients undergoing esophagogastroduodenoscopic biopsy at Seoul St. Mary's Hospital. Biopsies were performed with 100 disposable or 5 reusable forceps by random assignment. Seventy-five additional patients were studied to estimate durability of reusable forceps. The assisting nurses estimated the performance of the forceps. The evaluation of costs included purchase prices and reprocessing costs. The adequacy of the sample was estimated according to the diameter of the obtained tissue. RESULTS: Performance of disposable forceps was estimated as excellent in 97.0%, good in 2.0% and adequate in 1.0%. Reusable forceps were estimated as excellent in 36.0%, good in 36.0%, adequate in 25.1% and inadequate in 2.9%. The performance of reusable forceps declined with the number of uses. The reprocessing cost of reusable forceps for one biopsy session was calculated as 8,021won. The adequacy of the sample was excellent for both forceps. CONCLUSIONS: Disposable forceps showed excellent performance. Considering the reprocessing costs of reusable forceps, usage of disposable forceps with a low price should be considered.
