Nutrition assessment in long-term care facilities.

Elderly LTCF residents pose a challenging problem in terms of nutrition assessment at all three levels: intake, macronutrient, and micronutrient. In terms of macronutrient status, the focus of this work, newer techniques such as BIA and indirect calorimetry offer the promise of more accurate and widespread assessment in LTCFs. Future work will need to focus on the cost-effectiveness of this approach and on demonstrating that improved nutrition assessment can lead to better nutrition therapy and improved outcome.

Bronchoscope damage and repair costs: results of a regional postal survey.

Flexible fiberoptic bronchoscopy is a commonly performed procedure for which the indications, technical aspects, and potential patient complications have been well described. However, limited information is available regarding damage to the instrument itself. In order to better describe the types and causes of bronchoscope damage, repair costs, and time out of service, we performed a postal survey of hospital bronchoscopy laboratories in Alabama, Mississippi, and Louisiana. We received 43 completed surveys from laboratories that perform an average of 233 bronchoscopies per year. The respondents reported 103 episodes of bronchoscope damage, the majority of which consisted of damage to the bronchoscope cover, broken fiber bundles, malfunction of the bending apparatus, and suction channel damage. The respondents attributed 62% of all the damage to one of the three following categories: unknown, improper handling, and damage caused by biopsy forceps, brushes, or needles. Of the 103 episodes of bronchoscope damage, 66 (64%) were judged to be preventable, 13.6% not preventable, and 17.5% to be indeterminant. The average time out of service (mean, SD) for each damaged bronchoscope was 3.5 (3.9) weeks, and the average repair cost per episode of bronchoscope damage was $2,726.13 ($1,391.21). At least 19 episodes of bronchoscope damage occurred during cleaning and disinfecting procedures. We conclude that the majority of bronchoscope damage and repair costs should be potentially preventable and suggest that a program to familiarize all personnel handling bronchoscopes with proper maintenance and handling procedures should decrease the risk of bronchoscope damage.

Chronic cough as the sole presenting manifestation of gastroesophageal reflux.

Nine patients complaining only of chronic cough of unknown cause were prospectively studied with prolonged esophageal pH monitoring (EPM) before and after cough had disappeared as a complaint in order to determine if and why gastroesophageal reflux (GER) was causing their coughs. Coughs disappeared as a complaint an average of 161 +/- 75 days after medical therapy for GER. Comparisons of pretreatment and post-treatment EPM data revealed the following: numbers of coughs (p = 0.029), total refluxes (p = 0.001), refluxes greater than or equal to 5 min (p = 0.019), and reflux-induced coughs (p = 0.005) had significantly decreased in the distal esophagus, and total refluxes (p = 0.05) had significantly decreased in the proximal esophagus. During the entire study period, the number of coughs were significantly correlated with the number of total refluxes (p = 0.039), longest reflux (p = 0.019), number of refluxes greater than or equal to 5 min (p = 0.006), and percent of total time that pH was less than 4 (p = 0.017) in the distal esophagus. On the basis of these results, we conclude that (1) cough can be the sole presenting manifestation of GER, and it gradually responds to standard GER therapy; (2) prolonged EPM is safe, well-tolerated, and extremely useful in diagnosing clinically silent GER; (3) the mechanism by which GER causes cough is related to a critical number and/or duration of reflux episodes in the distal and/or proximal esophagus.
