[Financing of inpatient orthopedics and trauma surgery in the G-DRG system 2010]. / Finanzierung der stationären Orthopädie und Unfallchirurgie im G-DRG-System 2010.

BACKGROUND: The German DRG (diagnosis-related groups) system forms the basis for billing inpatient hospital services. It includes not only the case groups (G-DRGs), but also additional and innovation payments. This paper analyzes and evaluates the relevant developments of the G-DRG System 2010 for orthopedics and traumatology from the medical and classification perspectives. METHODS: Analyses of relevant diagnoses, medical procedures and G-DRGs in the versions 2009 and 2010 based on the publications of the German DRG institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI) were carried out. RESULTS: The DRG catalog is has grown from 8 to 1,200 G-DRGs. A number of codes for surgical measures have been newly established or modified. Here, the identification and the correct and performance-based mapping of complex and elaborate scenarios was again the focus of the restructuring of the G-DRG system. The G-DRG structure in orthopedics and traumatology has been changed, especially in the areas of spinal surgery and surgery of the upper and lower extremities. The actual impact of the changes may vary depending on the individual hospital services. CONCLUSION: For the first time since the introduction of the G-DRG system, the pure numerical changes at the level of DRGs themselves are so marginal that only part of the DRG users in the hospitals will register them. The changes implemented not only a high selectivity between complex and less complex scenarios, but partly also unintended and unjustified revaluation of less complex measures. The G-DRG system has gained complexity again. Especially the G-DRG allocation of spinal surgery and multiple surgical interventions of the upper and/or lower extremities have reached such a complexity that only a few DRG users can follow them.

Variation in specialist fees: evidence from New Zealand insurance claims.

OBJECTIVES: To examine the parity between specialties in reimbursements for surgical procedures in a private, fee-for-service setting and to ascertain whether differences exist after accounting for factors suggested by a Resource-Based Relative Value Scale (RBRVS). METHODS: A routinely updated database covering several private insurers (n = 8294 procedures from 1997 to 2002) was used to examine differences in overall and hourly reimbursement. Multiple regression analysis was used to control for factors that might be responsible for differences in payment (location, year, sex of patient and the associated anaesthetist fee). The resulting regression residuals were compared between specialties. RESULTS: Large differences between specialties in reimbursements were found in the overall amount paid. For most specialties, these differences were explained by factors such as time for procedure, location, complexity of procedure and sex of patients. However, hourly reimbursements for ophthalmologists were substantially higher (more than 50% above general surgery overall and 72% higher on an hourly basis). Some other smaller differences in overall and hourly reimbursement were also found. CONCLUSIONS: These results indicate that specialist fees vary significantly but many of the differences are explainable by factors incorporated into the RBRVS. However, significant variation remains for some specialties, most notably ophthalmology. Explanations for the results are discussed, including the possibility that political factors may influence the setting of specialist fees. This raises questions concerning the fairness of reimbursements and resulting solidarity within the medical profession.

The relationship between physician cost and functional status in the elderly.

OBJECTIVE: To explore the relationship between functional status and physician cost (general practitioner/specialist) in an elderly population. DESIGN, SETTING AND PARTICIPANTS: A longitudinal study involving 328 patients aged 65 years or over admitted to medical and surgical wards of a Sydney metropolitan hospital over a 10-month period. MAIN OUTCOME MEASURES: Two predictive cost models were developed using multiple linear regression analyses. Nine predictors were modelled including functional status (Short Form 36; SF-36) and major diagnostic categories. These models were then applied to the Australian SF-36 norms to produce a profile of cost by level of functioning. RESULTS: After adjusting for potential confounders, five variables were found to be predictive of general practitioner cost at a 5% significance level. Females and age were positively associated, whereas case note mention of post-discharge services and high SF-36 vitality and role emotional scores were negatively predictive. For specialist cost, five variables were statistically significant. The SF-36 domains of physical functioning and mental health were positively associated. Higher vitality, role emotional scores and case note mention of post-discharge services were negatively associated. CONCLUSIONS: Cost models can be used to highlight the differences between general practitioner and specialist attendances, guide future physician care of the aged, and facilitate informed decision making.

[OPS-301/ICPM: experiences and problems]. / OPS-301/ICPM: Erfahrungen und Probleme.

For over 2 years, the classification of procedures OPS-301 has been uniformly used in all German hospitals. The ICPM in German extension has 5-6 digits and is totally compatible with the OPS-301 restricted to operations. This ICPM is qualified for scientific documentation beyond efficiency control. The OPS-301 needs some better representation and some extensions proposed by medical experts. A program that searches for invalid code numbers and uses the relations of OPS-301 to sex, age, and department in a knowledge base, detects a 10% error rate in manual coding with OPS-301. A coding program reduces them to 1.4%. After mapping the OPS-301 by SNOMED this monohierarchical classification becomes multihierarchical. This is advantageous for coding and retrieval.

[Development of treatment guidelines and procedure guidelines within the scope of developing case fees and a modular quality management system (MQM)]. / Die Entwicklung von Behandlungsleitfäden und Verfahrensrichtlinien im Rahmen der Erarbeitung von Fallpauschalen und eines Modularen Qualitätsmanagement-Systems (MQM).

Since 1991 Diagnostic Related Groups (DRGs) are systematically developed for standardized operation procedures. They are included in a Quality Management System of the DIN EN ISO 9001 ff. norm and are part of the process system. In additional the internal and external evaluation of quality completes a Modular Quality Management System (MQM). These procedures meet the requirements for a Total Quality Management (TQM).

Medicaid physician fees, 1993.

In 1993 Medicaid physician fees were about 73 percent of Medicare payment levels and about 47 percent of private physician fees. Overall Medicaid fees grew by 15 percent from 1990 to 1993, slightly faster than Medicare or private-sector fees. However, there were considerable differences in fees across the states (from fourfold to thirty-ninefold between the lowest and highest states). Fees for maternity services varied the least. Medicaid fees generally were highest in Alaska, Arizona, Arkansas, Nevada, and Wyoming; they were lowest in New Jersey, New York, and Rhode Island.

Physician fee levels: Medicare versus Canada.

Adjusted for differences in purchasing power and practice expenses, Canadian physician fees are, on average, 59 percent of Medicare fees. The general perception that Medicare fees are low is the result of comparison with U.S. private fees, not to the much lower Canadian fees. In the context of the current U.S. health care system, lowering Medicare fees to Canadian levels could jeopardize access to care by Medicare beneficiaries. However, if all payers used the same fee schedule, fees that differed substantially from those currently used by private insurers might be viable.

Medical care price indexes: theory, construction & empirical analysis of the US series 1927-1990.

The historical development of price indexes as wage adjustment mechanisms is reviewed, as is the theory of aggregation and methods for dealing with quality and technological change. The construction of the U.S. Bureau of Labor Statistics (BLS) Medical Care Price Index (MCPI) is detailed. ARIMA analysis of the MCPI for the period 1927-1990 indicates that; (i) the MCPI is largely a damped and delayed function of the CPI, with an average lag of 8 months; (ii) medical care prices rose 2-4 percent faster than the all-items CPI since 1950, but not for 1927-1950; (iii) health expenditures are affected primarily by the general CPI, with little independent effect of specifically medical prices. The MCPI is a reliable measure of changes in consumer prices with strong construct validity. However, it was not designed for use as a deflator of medical expenditures, and is misleading when erroneously employed in that unintended role. The price/quantity duality and linear expenditure function which form the basis of Laspeyres price indexes are not applicable to nonconcatenable goods such as insurance or medical care. In these complex transactions, quality dominates quantity, fixed prices are replaced by reimbursement and professional judgement, and the assumption of additive separability required to use the price index as a deflator of health expenditures is not valid.
