[Trends in indication of selected laboratory methods by general practitioners]

General practitioners rely on laboratory methods for diagnostic decisions, but financial constraints influence usage patterns. Prior research has shown that preventive care protocols guide test selection in primary care settings. However, no prior work had resolved how point-of-care testing (POCT) adoption affects traditional lab method use. The financial regulation of healthcare services has driven efforts to rationalize diagnostic testing in primary care. Existing studies have established that glycaemia and liver enzyme tests are commonly requested in general practice. Yet, the specific trends in POCT implementation remain unclear. This gap motivated an analysis of longitudinal data from a major insurance provider. The study aimed to clarify how test selection and costs have evolved in primary care settings.

The study aimed to analyze trends in the use of laboratory diagnostics by general practitioners, focusing on cost patterns and test frequency. It sought to identify the most commonly requested tests in primary care settings. The researchers wanted to assess the impact of financial regulations on diagnostic testing behavior. They also aimed to track the adoption of point-of-care testing (POCT) in general practice. The study focused on whether test usage reflects rational decision-making by clinicians. It examined whether preventive care guidelines influence test selection. The analysis included data on expenditures for laboratory methods over time. The goal was to determine how diagnostic practices have evolved in primary care.

The study used data from Škoda Insurance Company to analyze trends in laboratory method usage. It focused on expenditures and test frequencies in general practice settings. The researchers categorized tests into routine and expensive diagnostic methods. They tracked changes in the use of point-of-care testing (POCT) over time. The analysis included comparisons between traditional lab methods and POCT. The study evaluated the most frequently requested clinical biochemistry tests. It also examined the proportion of tests performed in POCT mode. The data covered a long-term period to assess stability in diagnostic practices.

Expenditures for laboratory methods remained stable over the study period. Glycaemia, ALT, and AST were the most frequently requested tests in general practice. PSA, troponin, and tumor markers were among the most expensive tests used. The number of general practices adopting POCT increased significantly. Over half of INR tests were performed using POCT methods. Nearly half of CRP tests followed the same POCT trend. The data suggested a rational approach to diagnostic testing by general practitioners. The study found a growing reliance on point-of-care diagnostics in primary care.

The study found that general practitioners maintain stable spending on laboratory diagnostics. The most common tests included glycaemia and liver enzymes for routine monitoring. Financial regulations appear to influence test selection in primary care. The adoption of point-of-care testing (POCT) is increasing in general practice. Over half of INR tests now use POCT methods. The data suggest that diagnostic practices align with preventive care guidelines. The study supports the idea that general practitioners act rationally in test selection. The findings reflect current trends in diagnostic testing in primary care.
