A digital platform to support communication and organization in the general practice: Evaluation of healthcare usage and costs using claims data of a health insurer.

INTRODUCTION: The pressure on general practitioners (GPs) is rising due to the increasing demand for care and a decreasing availability of GPs. eHealth is seen as one of the solutions to enhance accessibility and reduce workload. A platform supporting the organization and communication in general practice has been developed offering services, such as econsultations. This study aims to evaluate healthcare usage and costs of patients using this platform by comparing these outcomes (1) before and after implementation and (2) an intervention with a matched control group. MATERIAL AND METHODS: This study is a retrospective observational cohort study. To evaluate the longitudinal impact of the implementation on healthcare usage, mixed model Poisson analyses were used with time as a factor term for the within-subject analysis and exposure to the platform as a factor term and an interaction term (i.e., exposure X 6-months) in the between-subject analysis. Cost analyses were done with mixed model analyses of variance over time. RESULTS: The total number of GP consultations significantly increased after compared to before implementation (i.e., Rate = 1.52; p < 0.001). The number of GP consultations was higher in the intervention compared to the control group (respectively, Rate = 1.23; p = 0.035). Healthcare costs increased for GP consultations after compared to before implementation (€13,57; p < 0.001). The costs for GP consults were significantly higher in the intervention compared to the control group (€7,06; p 0.018). CONCLUSION: This study showed a rise in GP consultations and costs when implementing a digital platform. This increase was presumably and partly caused by circumstances in one of the two included practices. Moreover, creating new options for contacting and communicating with the GP can enhance care accessibility and thereby driving an increase in consultations. This digital platform is a promising working method in general practice to facilitate patients and provide GPs with more flexibility.

A 66-year-old man presented with an ulcerating tumour on his abdomen, from which he suffered since three years and which was caused by a locally invasive colon carcinoma without evident metastases.

Can people affected by leprosy at risk of developing plantar ulcers be identified? A field study from central Ethiopia.

In the ALERT leprosy control programme, 75 people affected by leprosy, in three different geographical areas, were investigated. Each person was documented as having anaesthesia to the 10 g monofilament. The study sought to determine why some people developed ulcers whilst others did not. According to the records, 43 had an ulcer during the last 5 years but 32 had never had an ulcer. In order to examine protective sensation on the sole of the foot, various sensory modalities were tested and the functional anatomy of the foot was examined. The results showed, as may be expected, that it is not possible to define a specific threshold for protective sensation that could be applied to all cases. Some people with only slightly diminished sensation developed ulcers, while many others with almost complete anaesthesia remained ulcer-free. In these rural communities, being a farmer reduced the risk of developing an ulcer, but no other demographic features were significant. Graded monofilaments were found to be the most appropriate test, with loss of sensation at any of five points tested being a 'positive' result. The 10 g filament was the most sensitive, but only 43% of feet identified by this test actually developed an ulcer. As people with partial loss of sensation were excluded from this study, this figure may be lower under programme conditions. The 50 g and 100 g filaments decrease the number of feet identified as at risk, but increase the percentage which actually develop an ulcer, to 46% and 49%, respectively. An appropriate test for selecting those for special programmes which may have a limited capacity, for example the provision of subsidized footwear or involvement in self-care groups, would be a 100 g filament, which would detect 86% of those feet likely to develop an ulcer, while reducing the number of those selected who are not at great risk. Vibrometry was found to be no better than graded filaments and an examination of functional anatomy did not help in identifying those at risk.
