So...that is why I asked for some examples of dictation "without corrections"...Can you show it to us in action, please?
Here are a few paragraphs I dictated this am, using DNS Medical 10.1 and the Dictaphone PowerMike II:
He exercises several times a week for half an hour, by walking. His weight has remained stable, but slightly higher than recommended. I discussed his target by BMI, and recommended portion control. He doesn't use alternative medications.
In December 2009, a prostate biopsy done for elevated PSA showed prostate carcinoma. There was no evidence of metastasis by CT scan or bone scan. He has been followed by Dr. can't join and Dr. Looper for prostate cancer. He has some slow urination with hesitancy and nocturia x1, but no perineal pain or abnormal urinalysis. I discussed with him his options for treatment.
He has some dryness of his skin during the winter and has some itching and peeling around his ankles and arms. No redness or blisters. Topical creams are helpful.
He tests his sugar occasionally home, usually 1:30-160, rarely over 200. Never below 80. No polyuria, polydipsia, hypoglycemia, neuropathy, foot lesions, visual loss. I discussed a carbohydrate controlled diet and diabetic complications. He takes metformin in the evening. No dyspepsia or other side effects.
He continues lovastatin for treatment of high cholesterol without myalgias, weakness, headache or dyspepsia. I discussed phase I lipid diet and recommendations on weight loss and exercise.
No recent blood pressure checks at home. Continues medication regularly. No lightheadedness standing, chest pain, shortness of breath, weakness, muscle cramps, edema or palpitations.
Reflux symptoms rarely, well controlled by omeprazole taken daily. No symptoms of swallowing difficulty, abdominal pain, nausea, cough or sore throat.
You will notice that the errors are the physician name ("can't join" instead of "Cangiano") and it inserted "1:30" instead of 130 for the blood sugar reading. I do notice that error correction never seems to work with certain names. For instance "Katz" almost always gets dictated as "cats".
