How Accurate Are First Visit Diagnoses Using Synchronous Video Visits with Physicians?

BACKGROUND: Telediagnosis (TD), which uses information and communications technology, has recently undergone rapid development. Since no studies have compared the diagnostic precision of TD to that of face-to-face diagnosis (FD), we examined and compared the diagnostic accuracy of these diagnostic approaches among general medicine outpatients. METHODS: Data of 97 patients (45 men and 52 women with a mean age of 52 years) who underwent initial examinations at a regional hospital were analyzed. Two fully trained general medicine physicians were selected from a group of three physicians to perform FD and TD. Levels of agreement (as κ coefficients) were determined between TD and FD diagnoses as well as between final diagnoses and TD and FD diagnoses. RESULTS: The κ coefficients were 0.75 for TD and FD and 0.81 for both, the final diagnoses and the TD and FD diagnoses, revealing a sufficiently high level of diagnostic agreement. CONCLUSIONS: TD can provide the same level of diagnostic accuracy as FD among general medicine outpatients for adults. The help of medical assistants and the utilization of physical examination devices might enable medical staff to provide TD care similar in quality to FD. TD could be a useful diagnostic tool when medical work force is limited (e.g., in remote areas, during natural disasters, and in at-home care).

Satisfaction of Patients and Physicians with Outpatient Consultations at a University Hospital.

OBJECTIVE: This study was performed to investigate the factors influencing the correlation between physician satisfaction and patient satisfaction in an outpatient setting. METHODS: New patients attending the General Medicine Outpatient Clinic of Chiba University Hospital and their physicians were enrolled. After the initial consultation, both the patients and the physicians completed an anonymous questionnaire. RESULTS: There were 875 patients (381 men and 494 women; mean age: 54 years) and 10 physicians (4 men and 6 women; mean experience: 6 years). The satisfaction of the patients and the physicians was not correlated (r=0.14, p<0.001). A logistic regression analysis revealed that the factors associated with greater physician satisfaction were "guidance/advice from senior colleagues" [odds ratio (OR)=2.03; 95% confidence interval (CI)=1.76-2.34] and "confidence in the diagnosis" (OR=1.52; 95%CI=1.37-1.69), while "a difficult patient" (OR=0.73; 95%CI=0.68-0.78) was associated with reduced satisfaction. The factors associated with greater patient satisfaction were "the doctor listened carefully" (OR=1.98; 95%CI=1.62-2.42) and "my diagnosis is correct" (OR=1.57; 95%CI=1.41-1.74). One item in the questionnaire for the physicians, "I diagnosed psychogenic illness" (OR=0.87; 95%CI=0.81-0.94), was associated with lower patient satisfaction. CONCLUSION: The satisfaction of the patients and the physicians was not correlated. If only the factors promoting the satisfaction of one party are targeted, the satisfaction of the other party will not increase. The satisfaction of the physicians may be increased by receiving advice from mentors and an improved diagnostic ability, while the patients wants a physician who listens carefully and makes the correct diagnosis.

Influence of predicting the diagnosis from history on the accuracy of physical examination.

BACKGROUND: This study aimed to clarify the influence of predicting a correct diagnosis from the history on physical examination by comparing the diagnostic accuracy of auscultation with and without clinical information. METHODS: The participants were 102 medical students from the 2013 clinical clerkship course. Auscultation was performed with a cardiology patient simulator. Participants were randomly assigned to two groups. Each group listened to a different simulated heart murmur and then made a diagnosis without clinical information. Next, a history suggesting a different murmur was provided to each group and they predicted the diagnosis. Finally, the students listened to a murmur corresponding to the history provided and again made a diagnosis. Correct and incorrect diagnosis rates of auscultation were compared between students with and without clinical information, between students predicting a correct or incorrect diagnosis from the history (correct and incorrect prediction groups, respectively), and between students without clinical information and those making an incorrect prediction. RESULTS: For auscultation with or without clinical information, the correct diagnosis rate was 62.7% (128/204 participants) versus 54.4% (111/204 participants), showing no significant difference (P=0.09). After receiving clinical information, a correct diagnosis was made by 102/117 students (87.2%) in the correct prediction group versus 26/87 students (29.9%) in the incorrect prediction group, showing a significant difference (P=0.006). The correct diagnosis rate was also significantly lower in the incorrect prediction group than when the students performed auscultation without clinical information (54.4% versus 29.9%, P<0.001). CONCLUSION: Obtaining a history alone does not improve the diagnostic accuracy of physical examination. However, accurately predicting the diagnosis from the history is associated with higher diagnostic accuracy of physical examination, while incorrect prediction is associated with lower diagnostic accuracy of examination.

Osteomalacia due to a bladder reconstruction performed 35 years previously.

We report a 54-year-old man with osteomalacia due to a bladder reconstruction performed 35 years previously. He had had slowly progressive chest and back pain for 18 months. Osteomalacia due to metabolic acidosis was suspected based on hyperalkalinephosphatasemia and a high serum chloride level, and the diagnosis was confirmed by bone scintigraphy. His symptoms and blood electrolyte levels were improved by oral medication, including sodium hydrogen carbonate. Measurement of the serum chloride level is simple and useful for evaluating acidosis, for which a regular blood test is essential in patients who have undergone bladder reconstruction.
