Home blood glucose monitoring: effectiveness in a general population of patients who have non-insulin-dependent diabetes mellitus.

OBJECTIVE: To determine whether home blood glucose monitoring as used by non-insulin-dependent diabetes mellitus patients followed in primary care nonresearch clinics improves glycemic control or reduces utilization of the outpatient laboratory. DESIGN: A retrospective chart review for 229 patients receiving outpatient supplies for home testing of either blood or urine. SETTING: A variety of nonresearch clinics at a Veterans Affairs Medical Center, a teaching hospital affiliated with an academic university medical center. PATIENTS: Outpatient veterans followed in diabetes, primary care, internal medicine, or endocrine clinics. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The mean glycosylated hemoglobin for an unselected group monitoring glycemic control by urine testing only was 11.32% and for those using blood monitoring was 11.37%. Frequency and duration of monitoring had no apparent impact on glucose control. There was no decrease in the utilization of the laboratory among those patients practicing home blood glucose monitoring. CONCLUSIONS: For non-insulin-dependent diabetic patients followed in a nonresearch clinic setting, the benefits of home blood glucose monitoring remain to be proven.

Leg symptoms in outpatient veterans.

In a survey of outpatients at the Denver Veterans Affairs Medical Center for common leg symptoms--515 questionnaires returned in a 3-week period--56% reported nocturnal leg cramps, 29% reported the restless leg syndrome, and 49% reported symptoms of peripheral neuropathy. Only 33% of patients had no symptoms relating to their legs. Patients often did not report these symptoms to their physician but were more likely to do so if the symptoms were frequent. Conditions especially related to leg symptoms were hypertension, peripheral vascular disease, coronary artery disease, cerebrovascular disease, kidney disease, and hypokalemia. Most patients did not receive effective therapy for these symptoms.

Treatment of an influenza A outbreak in a teaching nursing home. Effectiveness of a protocol for prevention and control.

The safety and efficacy of current ACIP guidelines for the prevention and control of influenza in nursing home populations are uncertain. An outbreak of influenza A/Sichuan (H3N2) in a teaching nursing home during 1988 gave us the opportunity to evaluate the effectiveness of an influenza vaccination and amantadine prophylaxis protocol. Over 13 days, 12 of 60 residents developed influenza. Prior influenza vaccination had been given to 94% of the residents. Protection from infection occurred in those tested who had antibody levels greater than or equal to 1:16 to the A/Leningrad (H3N2) antigen contained in the standard 1987-88 trivalent vaccine. However, five of 17 vaccinated residents who were tested had antibody levels less than or equal to 1:16 at the start of the outbreak. Amantadine (less than or equal to 100 mg/day) was given to all but one resident starting on the third day of the outbreak, and to employees starting on the sixth day of the outbreaks. Seven residents developed illness after the start of amantadine, although amantadine appeared to ameliorate their symptoms. Although amantadine was generally well tolerated by residents, employees receiving amantadine identified a high incidence of side effects and only 44% of employees took at least 70% of the prescribed amantadine. In our opinion, early detection and protocol-directed intervention probably abated a more severe influenza outbreak. Therefore we support existing recommendations that formal nursing home policies be established to ensure that residents and employees receive annual influenza vaccine and that chemoprophylaxis be used when outbreaks of influenza A are suspected.

The periodic physical examination in asymptomatic adults.

The components of the periodic physical examination have been evaluated according to contemporary epidemiologic standards. For the asymptomatic, nonpregnant adult of any age, no evidence supports the need for a complete physical examination as traditionally defined. The efficacy for three screening procedures has been established: Blood pressure should be measured at least every 2 years; women more than 40 years of age should have a breast examination done by a physician annually; and sexually active women should have a pelvic examination and a Papanicolaou test at least every 3 years after two initial negative tests have been obtained 1 year apart. Because of the prevalence and morbidity of specific diseases, and the sensitivity and specificity of screening tests, several other maneuvers are recommended for screening asymptomatic adults, although the optimal frequency has not been determined experimentally. Weight should be measured every 4 years. Visual acuity should be tested annually in adults older than 60 years of age. To identify patients at high risk for melanoma, a complete skin examination should be done once. Hearing should be tested by audioscope annually in adults older than 60 years of age. Physicians should encourage patients to have annual dental visits. To identify valvular abnormalities requiring antibiotic prophylaxis, cardiac auscultation should be done at least twice in an adult. Men older than 60 years of age should have a yearly examination of the abdomen for the presence of aortic aneurysm. Although the other components of the complete physical examination may be important in establishing and maintaining the physician-patient relationship, they have not been shown to be effective screening maneuvers for asymptomatic disease.

Brain death and persistent vegetative states.

Patients who suffer severe brain damage may be brain dead, even though their cardiorespiratory function is supported by mechanical ventilation. According to criteria established in the United Kingdom and the United States, if these patients meet the preconditions of apneic coma that is attributable to diagnosed irreversible cause, and the presence of drug intoxication, hypothermia, or metabolic coma is excluded, then documentation of absent brainstem reflexes and apnea despite a PaCO2 of 50 mm Hg or greater will confirm the presence of brain death. If the brain is dead, the patient is dead, regardless of the state of his circulation, and he should be declared dead and removed from the ventilator. If the patient has lost higher cortical function but brainstem function is preserved, he may be in the persistent vegetative state and live for years with apparent sleep-wake cycles but no awareness of any external or internal stimuli. As the prognosis for recovery from the persistent vegetative state is absent, there is no ethical responsibility to continue treatment other than to provide basic nursing care to maintain the dignity of the patient.

A mobile internal medicine clinic.

The Denver Veterans Administration Medical Center (DVAMC) established a mobile internal medicine clinic (MediVAn) to provide access to primary care for veterans living more than fifty miles from the center and to study the costs of such an outreach program. A fully equipped van staffed by an internist visited four Colorado cities weekly for scheduled appointments. In the first two years of operation there were 4,655 visits by 766 veterans with a mean age of 56 years, with 3.9 diagnoses, and receiving 3.0 medicines. The cost per MediVAn visit was $68, compared with $67 per outpatient visit at DVAMC. We conclude that a mobile medical clinic is a convenient method of delivering primary care over distances and is comparable in cost to outpatient hospital visits.
