Determinants of Medical Direct Costs of Care among Patients of a Memory Center.

BACKGROUND: Alzheimer's disease and related diseases (ADRD) are a major cause of health-related cost increase. OBJECTIVES: This study aimed to estimate the real medical direct costs of care of patients followed at a memory center, and to investigate potential associations between patients' characteristics and costs. DESIGN: Cross-sectional analyses conducted on matched data between clinical data of a cohort of patients and the claims database of the French Primary Health Insurance Fund. SETTING: Memory center in France. PARTICIPANTS: Patients attending a memory center with subjective cognitive complaint. MEASUREMENTS: Medical or nonmedical direct costs (transportation) reimbursed by the French health insurance during the one year after the first memory visit, and socio-demographic, clinical, cognitive, functional, and behavioral characteristics were analyzed. RESULTS: Among 2,746 patients (mean ± SD age 79.9 ± 8 years, 42.4% of patients with dementia), the total direct cost was on average € 9,885 per patient during the year after the first memory visit: € 7,897 for patients with subjective cognitive complaint, € 9,600 for patients with MCI, and € 11,505 for patients with dementia. A higher functional and cognitive impairment, greater behavioral disorders, and a higher caregiver burden were independently associated with a higher total direct cost. A one-point decrease in the Instrumental Activities of Daily Living score was associated with a € 1,211 cost increase. The cost was higher in patients with Parkinson's disease, and Lewy body disease compared to patients with AD. Diabetes mellitus, anxiety disorders and number of drugs were also significantly associated with greater costs. CONCLUSIONS: Higher real medical direct costs were independently associated with cognitive, functional, and behavioral impairment, diabetes mellitus, anxiety disorders, number of drugs, etiologies as well as caregiver burden in patients attending a memory center. The identification of factors associated to higher direct costs of care offers additional direct targets to evaluate how interventions conducted in patients with NCD impact direct costs of care.

Economic impact of harmonizing medical practices: compliance with clinical practice guidelines in the follow-up of breast cancer in a French Comprehensive Cancer Center.

PURPOSE: The introduction of clinical practice guidelines (CPGs) and the increasing desire to harmonize clinical practices draw attention to the economic impact of these trends. In 1994, CPGs were introduced in a French Comprehensive Cancer Center (Centre Régional Léon Bérard, Lyon). We evaluated the application of these CPGs in addition to the consequences of harmonizing clinical practices with respect to the distribution of resources by specifically analyzing the posttherapeutic follow-up of patients with localized breast cancer. METHODS: A before-and-after analysis of the records of patients who received posttherapeutic follow-up for localized breast cancer as of either 1993 or 1995 was performed. Two hundred records were chosen at random, 100 from 1993 and 100 from 1995. Follow-up was continued for as long as possible and CPG compliance was studied for each year of the follow-up periods. RESULTS: Follow-up that was not CPG-compliant required a significantly greater amount of resources. This difference was due to neither consultations nor mammographies, but was due to other examinations that were systematically performed without any warning signs to justify them. Depending on the follow-up year, noncompliant follow-up cost the Social Security from 2.2 to 3.6 times more than compliant follow-up. A noticeable change in medical practices was observed after the introduction of CPGs in 1994. This was confirmed by a sharp decrease in mean Social Security expenditure per patient of more than one third between 1993 and 1995, regardless of the follow-up year considered. CONCLUSION: In the follow-up of patients with localized breast cancer, a large decrease in costs has been observed along with the evolution of medical practices toward CPG compliance. This finding is probably generalizable to other settings, but there is nothing that proves that it is applicable to other treatment strategies.

Analysis of the eligibility of published economic evaluations for transfer to a given health care system. Methodological approach and application to the French health care system.

CONTEXT: Economic evaluations are costly and cannot always be carried out locally. Therefore, decision-makers may wish to use studies already performed in other settings. OBJECTIVE: To define a method for assessing the eligibility of published economic evaluations for transfer to a given health care system and apply it to the french health care system in the clinical situation of adjuvant therapy for women with breast cancer. METHODS: (1) Literature search in six databases from 1982 to 1996; (2) critical appraisal of articles based on four inclusion criteria; and (3) assessment of the eligibility of the studies for transfer based on five indicators. RESULTS: We identified 26 published economic evaluations concerning adjuvant therapy in women with breast cancer. Six (23%) met all four criteria used to select studies, but none of these studies were eligible for transfer to the french health care system. The main reason was that cost data was not reported in a transparent way. CONCLUSIONS: To improve the transferability of economic evaluations, we recommend that requirements for data provision in publications be standardized and international collaboration strengthened.

[Integration of economic criteria in the recommendations for clinical practice in cancerology]. / Intégration des critères économiques dans les recommandations pour la pratique clinique en cancérologie.

Clinical practice guidelines have been defined as "systematically developed statements to assist practitioners and patients in their decisions about appropriate health care for specific clinical circumstances". Their objectives are to improve the quality of health care and to optimise the use of limited health care resources. However reduction of unnecessary costs of delivered health care is proceed most often in an implicit way by identifying inappropriate health care strategies. The increase of health care costs needs to look at this issue in a more explicit way and to consider costs in the guideline development process. The key objective of our study is to analyse the methodological aspects of dealing with cost issues in the guideline development process. The integration of cost issues is in fact limited by two major problems: first, the lack of economic evaluation for many strategies in the scientific literature and second, the lack of generalizability of the published results to temporally and/or geographically different settings. These difficulties are likely to result in the need for local cost evaluation (for a given setting), and though to make the guideline development process much more complex. Further methodological research is important to define the role of economic evaluation in clinical practice guidelines and to enable the integration of cost issues into the guideline development process. They should go closely together with international standardisation of the methodology for designing, conducting and reporting economic evaluation.
