The goal of this study was to compare the Oxford Shoulder Score (OSS), the Shoulder Pain and Disability Index (SPADI), and the Short Form 36 (SF-36) for their correlation, agreement, sensitivity to change, and test-retest reliability in patients with a clinical diagnosis of subacromial impingement. All patients attending a specialist subacromial impingement clinic over a 6-month period completed the OSS, SPADI, and SF-36 at each visit. A total of 323 sets of observations were recorded in 110 patients. The first 38 of these patients were also sent the questionnaires to complete before their visit. There was good correlation between the OSS and SPADI scores (correlation coefficient = 0.85) and good agreement between the scores on each scale (weighted kappa = 0.79). The correlation with total SF-36 was poor (0.37 for OSS and 0.26 for SPADI). The OSS and SPADI showed good effect sizes compared with the total SF-36 score and good test-retest reliability. These data support the use of the OSS or SPADI in patients with subacromial impingement.

Problem drinkers among acute care inpatients.

AIM: The objective of this study was to determine the prevalence of potential problem drinking among general hospital inpatients during a three-month period. METHOD: The study was conducted in a large Scottish teaching hospital. The wards involved were the general medical, general surgical, orthopaedic and short-stay wards as they had been identified as clinical areas with problem drinking among inpatients. Patients were interviewed using a structured interview schedule as a screening instrument to detect potential problem drinkers. RESULTS: Of the patients interviewed, 25 per cent were shown to drink in excess of the BMA's guidelines for low-risk drinking: 8 per cent had had previous treatment for alcohol problems; 2 per cent were bout or seasonal drinkers; and 15 per cent were newly identified potential problem drinkers. Of the newly identified group, 75 per cent were men and 25 per cent women. Those who were unemployed formed the largest group of potential problem drinkers according to occupation, and patients from the short-stay ward were more likely to have an alcohol problem than those from other wards in the study. CONCLUSION: The patients in this study found to be at risk of experiencing alcohol-related problems might not be routinely identified with current screening methods. This method of screening, by asking patients about their recent drinking patterns, will help nurses to identify those who are potential problem drinkers and enable them to provide relevant advice and education to these patients.

Automated system for measurement of mechanics of breathing.

We describe a complete automated system for measurement of total respiratory resistance and compliance, and of pulmonary resistance and compliance in humans and anesthetized animals. The device for testing the chest-lung system consists of a sinusoidal pump with a stroke adjustable from 20 ml to 600 ml over a cycling frequency of 0.3 to 30 Hz. Pressure and flow or volume are inputted into an analog network for wave shaping, then to an arithmetic unit composed of sample-and-hold amplifiers, peak, minimum and zero detecting circuits, an analog division circuit, and a digital logic processor. The computer takes the peak-to-peak amplitude of one of two sinusoidal inputs at 0.3 to 10 Hz and the corresponding amplitude of the other input in the presence of a.c. noise and d.c. shifts, divides one into the other, and displays an answer on a digital voltmeter. In addition, the analog output is displayed on the cathode-ray tube of a storage oscilloscope. Plots of total resistance and pulmonary resistance are recorded as a function of lung volume in both humans inspiring voluntarily as well as anesthetized dogs inflated by positive pressure from the test apparatus. Total and pulmonary dynamic compliance, as a function of breathing frequency, can only be measured by the computer if a symmetrical waveform is presented to it. This cannot be achieved in spontaneously breathing subjects but is accomplished in apneic animals by producing sinusoidal oscillations from the test apparatus. Our on-line method for measurement of total respiratory resistance is now used in the Clinical Pulmonary Laboratory for experimental work, and we are in the process of obtaining values in normal subjects.
