ABSTRACT
OBJECTIVE: To evaluate the appropriateness of magnetic resonance imaging (MRI) of the knee requested by primary care physicians. DESIGN: Retrospective observational study. SETTING: Six primary care centres in the Elche Department of Health of the Valencian Community, Spain. PARTICIPANTS: Three hundred patients with knee pain who were prescribed MRI. MAIN OUTCOME MEASURES: Data were collected from the electronic clinical history, which allowed us to assess the appropriateness and inappropriateness of the MRI requests for the knee based on the American College of Radiology (ACR) criteria. A multivariate logistic regression model was used to identify factors associated with an inappropriate request. RESULTS: About 45% (41-49%) of knee MRI prescriptions were assessed as inappropriate. The frequency was higher in female patients (odds ratio, OR = 1.96; P = 0.03). A history of knee trauma and urgent use of MRI were associated with a lower frequency of inappropriate requests (OR = 0.14, P < 0.001 and OR = 0.32, P = 0.03, respectively). In 82% of cases, the request for MRI was deemed inappropriate because it was used as the initial imaging test. The availability of a previous radiograph of the knee significantly reduced the rate of inappropriate requests (OR = 0.05, P < 0.001); only 47% of the patients had a previous radiograph. CONCLUSIONS: The percentage of inappropriate knee MRI prescriptions is high. Protocols should be put in place to improve the appropriateness of MRI requests by promoting understanding of the appropriate use of MRI among primary care physicians.

OBJECTIVE: To determine the prevalence of patients with multiple chronic diseases in Primary Care using the multiple morbidity criteria and Clinical Risk Groups, and the agreement in identifying high-risk patients that require case management with both methods. MATERIAL AND METHOD: A cross-sectional study was conducted on 240 patients, selected by random sampling of 16 care quotas from two Primary Health Care centres of a health area. Informed consent was obtained to access their electronic medical records for the study, and a record was made of age, sex, health status of Clinical Risk Groups, severity, multiple morbidity criteria, and Charlson index by physicians during clinical practice. Three patients were excluded due to incomplete data. RESULTS: The prevalence of patients with multiple chronic diseases following the criteria of the Ministry of Health among users was 4.11 (95% CI; 2.13-7.30). The frequency of patients with high risk Clinical Risk Groups (G3) in the chronicity strategy of Valencian Community was 7.59 (95% CI; 4.70-11.70), which includes patients with health status 6 and complexity level 5-6, and health status 7, 8, and 9. Agreement between the two classifications was low, with a kappa index 0.17 (95% CI; 0-0.5) CONCLUSIONS: The prevalence did not differ significantly from that expected, and the agreement between the two stratifications was very weak, not selecting the same patients for highly complex case management.
