Reengineering along departmental product flowlines

This article describes how a medical records department responded to relocating, upgrading a departmental computer system, incorporating severity of illness abstracting, and implementing continuous quality improvement techniques by reengineering along department flowlines over a five-year period. Areas of the department that were restructured were storage and retrieval, record completion, and data collection and reporting functions.     

Patient Satisfaction and Results of Vertical Banded Gastroplasty and Gastric Bypass

Background: Morbid obesity contributes to many health risks, including physical, emotional, and social problems. Various surgical treatments for morbid obesity have developed and have so far met with good results. This study compares vertical banded gastroplasty (VBG) with gastric bypass (GBP) and the patients' satisfaction with either procedure. Methods: Between April 1993 and July 1997, 63 bariatric surgical procedures were performed at Eisenhower Army Medical Center. Of those, complete follow-up was obtained for 29 patients. The parameters evaluated included age, preoperative and postoperative weights, body mass index (BMI), type of surgery, complications, and the patient's level of satisfaction. Results: The study group consisted of 27 women and 2 men. The average preoperative weight was 135 kg, and the average preoperative BMI was 48.3 kg/m². There were 17 VBGs and 12 GBPs performed. The average total weight loss was 45.1 kg. The average postoperative BMI was 33.2 kg/m². There were no statistically significant differences in weight loss between VBG and GBP. Four of 17 patients had complications after VBG, and three of 12 patients had complications after GBP. After VBG, 94.1% of patients were satisfied, and after GBP, 100% were satisfied. Twenty-seven of 28 patients stated that they would have the surgery again. Conclusion: There were no statistically significant differences in weight loss or complications after VBG or GBP. Patient satisfaction was high after both procedures. Therefore, bariatric surgery is important in the treatment of appropriately selected, morbidly obese patients.     

The in vitro effects of instrumentation on multilevel cervical strut-graft mechanics

STUDY DESIGN: Biomechanical study using a programmable testing apparatus that replicated physiologic flexion-extension cervical spine motion, and loading mechanics. OBJECTIVES: To determine the influence of anterior, posterior, or combined plating on multilevel cervical strut-graft mechanics in vitro. SUMMARY OF BACKGROUND DATA: The addition of instrumentation does not prevent construct failure in multilevel (more than two levels) cervical corpectomy. METHODS: Six fresh human cadaveric cervical spines (C2-T1) were tested in six sequential conditions that included harvested (H), C4-6 corpectomy, strut grafted, strut grafted with an anterior cervical plate (SGAP), strut grafted with posterior plates (SGPP), and strut grafted with combined anterior and posterior plates (SGAPP). A customized force-sensing strut graft (FSSG) was used to measure axial compression-tension, flexion-extension and lateral bending moments, and axial torsion. Parameters of stiffness, segmental vertebral motion, and strut-graft loads were compared, to determine differences among the spine conditions. RESULTS: Flexion of the strut-grafted spine loaded the FSSG, and extension motion unloaded the FSSG. With the anterior plate, flexion of the SGAP spine significantly unloaded the FSSG; extension loaded the FSSG more than flexion of the unplated spine (P = 0.03). The opposite occurred with the posterior plates (SGPP), where flexion of the spine significantly loaded the FSSG (more than the strut grafted spine) and extension unloaded the FSSG (P < 0.03). The combined construct (SGAPP) counteracted the tension band effect of the individual plates and demonstrated significantly less overall FSSG load change than either plate alone (P = 0.03). CONCLUSIONS: Multilevel cervical instrumentation effectively increases stiffness after corpectomy. However, anterior or posterior plating alone excessively loads the graft with small degrees of motion, which may promote pistoning and failure of multilevel constructs.     

Educating lay carers of people with learning disability in epilepsy awareness and in the use of rectal diazepam: a suggested teaching protocol for use by healthcare personnel

A high proportion of people with learning disabilities have epilepsy and often their epilepsy is of an intractable nature. Nurses within the large learning disability institutions are obliged, on a regular basis, to administer rectal diazepam to control these patients' serial seizures. As a result of the "community care" initiative, the process of discharging adult people from institutions into care settings in the community is underway. Consequently, and increasingly, the learning disabled are being cared for by non-medical/non-nursing (lay) community home carers who are required to gain a working knowledge of epilepsy as well as a degree of proficiency in the first aid management of seizures and in the use of rectal diazepam. Medical and nursing staff involved in the care of adults with learning disability are now liable to be approached by lay care organisations for appropriate training. This article, therefore, will outline the training programme employed at Gogarburn Hospital to educate lay community care staff in general epilepsy awareness and in the administration of rectal diazepam to adults with learning disability and epilepsy. This programme could be adapted and implemented by colleagues in their own areas.     

Effect of labeling and teacher behavior on children's attitudes.

Seventy-eight fourth-grade subjects from a rural school containing an integrated special-education program viewed one of two videotapes that depicted a child demonstrating various kinds of academic and social behavior. On one tape, the teacher reacted positively to the child's behavior; on the other, negatively. The subjects were told that the child on the tape was either a "normal," mentally retarded, or learning-disabled fourth grader. The subjects were randomly assigned to one of two teacher conditions (positive or negative) and one of three labeling conditions. After viewing the videotape, the subjects filled out a peer-acceptance questionnaire concerning the child on the videotape. Results indicated that across all labeling conditions the subjects rated the child higher on the questionnaire when the child was reacted to positively by the teacher and, further, that the "mentally retarded" label led to significantly higher peer-acceptance ratings than did the "normal" or "learning-disabled" label.     

Comparative mortality of hemodialysis and peritoneal dialysis in Canada

BACKGROUND: Comparisons of mortality rates in patients on hemodialysis versus those on peritoneal dialysis have been inconsistent. We hypothesized that comorbidity has an important effect on differential survival in these two groups of patients. METHODS: Eight hundred twenty-two consecutive patients at 11 Canadian institutions with irreversible renal failure had an extensive assessment of comorbid illness collected prospectively, immediately prior to starting dialysis therapy. The cohort was assembled between March 1993 and November 1994; vital status was ascertained as of January 1, 1998. RESULTS: The mean follow-up was 24 months. Thirty-four percent of patients at baseline, 50% at three months, and 51% at six months used peritoneal dialysis. Values for a previously validated comorbidity score were higher for patients on hemodialysis at baseline (4.0 vs. 3.1, P < 0.001), three months (3.7 vs. 3.2, P = 0.001), and six months (3.6 vs. 3.2, P = 0.005). The overall mortality was 41%. The unadjusted peritoneal dialysis/hemodialysis mortality hazard ratios were 0.65 (95% CI, 0. 51 to 0.83, P = 0.0005), 0.84 (95% CI, 0.66 to 1.06, P = NS), and 0. 83 (95% CI, 0.64 to 1.08, P = NS) based on the modality of dialysis in use at baseline, three months, and six months, respectively. When adjusted for age, sex, diabetes, cardiac failure, myocardial infarction, peripheral vascular disease, malignancy, and acuity of renal failure, the corresponding hazard ratios were 0.79 (95% CI, 0. 62 to 1.01, P = NS), 1.00 (95% CI, 0.78 to 1.28, P = NS), and 0.95 (95% CI, 0.73 to 1.24, P = NS). Adjustment for a previously validated comorbidity score resulted in hazard ratios of 0.74 (95% CI, 0.58 to 0.94, P = 0.01), 0.94 (95% CI, 0.74 to 1.19, P = NS), and 0.88 (95% CI, 0.68 to 1.13, P = NS) at baseline, three months, and six months. There was no survival advantage for either modality in any of the major subgroups defined by age, sex, or diabetic status. CONCLUSIONS: The apparent survival advantage of peritoneal dialysis in Canada is due to lower comorbidity and a lower burden of acute onset end-stage renal disease at the inception of dialysis therapy. Hemodialysis and peritoneal dialysis, as practiced in Canada in the 1990s, are associated with similar overall survival rates.     

Comparative hospitalization of hemodialysis and peritoneal dialysis patients in Canada

BACKGROUND: Most comparisons of hemodialysis (HD) and peritoneal dialysis (PD) have used mortality as an outcome. Relatively few studies have directly compared the hospitalization rates, an outcome of perhaps equal importance, of patients using these different dialysis modalities. METHODS: Eight hundred twenty-two consecutive patients at 11 Canadian institutions with irreversible renal failure had an extensive assessment of comorbid illness and initial mode of dialysis collected prospectively immediately prior to starting dialysis therapy. The cohort was assembled between March 1993 and November 1994. The mean follow-up was 24 months. Admission data were used to compare hospitalization rates in HD and PD. RESULTS: Thirty-four percent of patients at baseline and 50% at three months used PD. Twenty-five percent of HD and 32% of PD patients switched dialysis modality at least once after their first treatment (P = NS). Nine percent of HD patients and 30% of PD patients switched modality after three months (P < 0. 001). Total comorbidity was higher in HD patients at baseline (P < 0. 001) and at three months (P = 0.001). The overall hospitalization rate was 40.2 days per 1000 patient days after baseline and 38.0 days per 1000 patient days after three months. When an adjustment was made for baseline comorbid conditions, patients on PD had a lower rate of hospitalization in intention-to-treat analysis according to the type of dialysis in use at baseline (RR 0.85, 95% CI, 0.82 to 0.87, P < 0.001), but a higher rate according to the type of dialysis in use three months after study entry (RR 1.31, 95% CI, 1.27 to 1.34, P < 0.001). In analyses based on the amount of time actually spent on each treatment modality, PD was associated with a higher rate of hospitalization when analyzed according to the type of dialysis in use at baseline (RR 1.10, 95% CI, 1.07 to 1.13, P < 0.001) and according to the type of dialysis in use three months after study entry (RR 1.26, 95% CI, 1.23 to 1.30, P < 0.001). CONCLUSIONS: Conclusions regarding comparative hospitalization rates are heavily dependent on the analytic starting point and on whether intention-to-treat or treatment-received analyses are used. When early treatment switches are accounted for, HD is associated with a lower rate of hospitalization than PD, but the effect is modest.
