TQI in the Albuquerque Veterans Affairs Medical Center's long-term oxygen therapy program.

BACKGROUND: Long-term oxygen therapy (LTOT) is the only treatment demonstrated to prolong the life of patients with chronic obstructive pulmonary disease. In November 1994, a multidisciplinary total quality improvement (TQI) team composed of the involved hospital services was established to reorganize and improve the LTOT program at the Albuquerque Veterans Affairs Medical Center (AVAMC), Albuquerque. FROM THE OLD TO THE NEW PROCESS: The LTOT team used a process map to analyze the current process and gather information from patients and staff regarding their satisfaction with the program. It then began working on the identified problems and streamlining the LTOT referral process. A respiratory therapy position with the specific responsibility of serving as the home oxygen (O2) coordinator (HOC) was established and filled. The evaluation process was to be initiated by the AVAMC physicians, following which the HOC would perform a newly standardized evaluation that would establish the patient's need for O2 and result in a specific prescription. RESULTS: Quality indicators were selected to monitor changes in the program. Data from chart reviews, the Veterans Affairs National Cost Containment Center, and patient surveys were used to evaluate the indicators. Timeliness of referral to the program before inpatient discharge improved, O2 prescriptions in the new program more frequently addressed activity, and the cost per patient was reduced by 37.1%. Patient satisfaction rates also improved. DISCUSSION: A motivated team with representatives of the services involved was able to analyze and dramatically improve an important but complicated program.

Exercise training by individuals with predialysis renal failure: cardiorespiratory endurance, hypertension, and renal function.

The purpose of this study was to determine the effects of 4 months of exercise training (ET) on cardiorespiratory function and endurance, blood pressure, muscle strength, hematology, blood lipids, and renal function in individuals with chronic renal failure (CRF) who were not yet on dialysis. Sixteen subjects were recruited to volunteer for participation in this study, but only eight completed all study phases. Subjects were first evaluated before and after a 2-month baseline (BL1 and BL2), after 4 months of ET, and again after 2 months of detraining (DT). ET did not change hematology, blood lipids, or echocardiographic measurements of left ventricular function and mass. Resting systolic and diastolic blood pressures decreased significantly from BL after the ET (146 +/- 15.7/87 +/- 9 mm Hg to 124 +/- 17.5/78 +/- 9.5 mm Hg; P < 0.02), and then increased significantly after DT (139 +/- 14.7 mm Hg and 87 +/- 9.9 mm Hg; P < 0.01). Peak oxygen consumption (pVO2) changed significantly during the study (1.3 +/- 0.3 L/min, 1.5 +/- 0.3 L/min, and 1.4 +/- 0.3 L/min for BL2, ET, and DT, respectively; P < 0.02), as did the VO2 at the ventilatory threshold (0.65 +/- 0.18 L/min, 0.92 +/- 0.19 L/min, and 0.68 +/- 0.23 L/min for BL2, ET, and DT, respectively; P < 0.01). Knee flexion peak torque increased after ET (43.4 +/- 25.6 Nm to 51.0 +/- 30.5 Nm; P < 0.02). GFR, as measured by creatinine clearance, continued to deteriorate during the course of the study (25.3 +/- 12.0 mL/min, 21.8 +/- 13.2 mL/min, and 21.8 +/- 13.2 mL/min for BL2, ET, and DT, respectively; P < 0.001). Individuals with predialysis CRF who undergo ET improve in functional aerobic capacity, muscular strength, and blood pressure.

Pre-exercise glycerol hydration improves cycling endurance time.

The effects of glycerol ingestion (GEH) on hydration and subsequent cycle ergometer submaximal load exercise were examined in well conditioned subjects. We hypothesized that GEH would reduce physiologic strain and increase endurance. The purpose of Study I (n = 11) was to determine if pre-exercise GEH (1.2 gm/kg glycerol in 26 ml/kg solution) compared to pre-exercise placebo hydration (PH) (26 ml/kg of aspartame flavored water) lowered heart rate (HR), lowered rectal temperature (Tc), and prolonged endurance time (ET) during submaximal load cycle ergometry. The purpose of Study II (n = 7) was to determine if the same pre-exercise regimen followed by carbohydrate oral replacement solution (ORS) during exercise also lowered HR, Tc, and prolonged ET. Both studies were double-blind, randomized, crossover trials, performed at an ambient temperature of 23.5-24.5 degrees C, and humidity of 25-27%. Mean HR was lower by 2.8 +/- 0.4 beats/min (p = 0.05) after GEH in Study I and by 4.4 +/- 1.1 beats/min (p = 0.01) in Study II. Endurance time was prolonged after GEH in Study I (93.8 +/- 14 min vs. 77.4 +/- 9 min, p = 0.049) and in Study II (123.4 +/- 17 min vs. 99.0 +/- 11 min, p = 0.03). Rectal temperature did not differ between hydration regimens in both Study I and Study II. Thus, pre-exercise glycerol-enhanced hyperhydration lowers HR and prolongs ET even when combined with ORS during exercise. The regimens tested in this study could potentially be adapted for endurance activities.

Smoking policy and cessation in an inner-city hospital.

Hospital policies regarding cigarette smoking can affect the smoking habits of employees, patients, and visitors. Successful smoking policy development and impact have been reported in a number of hospitals. These reports have been from financially secure or university hospitals. This article reports on the policy experience at Interfaith Medical Center, a public hospital serving an economically disadvantaged black inner-city community. Policy implementation and smoking cessation efforts were directed by a broad-based hospital committee. An employee survey demonstrated support for a policy restricting but not banning smoking (89% of nonsmokers, and 80.2% of smokers). Among smoking employees, 87.6% wanted to quit. A policy restricting smoking to designated areas in the cafeteria and coffee shop was enacted. Health fairs and smokeout contests were enthusiastically received and resulted in short-term cessation verified by exhaled carbon monoxide levels. Assemblies where ex-smokers were given "Hall of Fame" certificates, "stop smoking" art contests, and a "stop smoking hotline" generated further cessation activity. The department of medicine, in cooperation with the National Heart, Lung, and Blood Institute's Smoking Education Program, set up a training program for residents on how to help patients quit. Overall, the smoking prevalence, attitudes, and enthusiasm to quit were similar to previous reports in financially secure hospitals. Unfortunately, lack of resources and staff turnover led to dissolution of the program. Institutional stability and a funding source are critical for the long-term success of hospital smoking cessation programs.

An evaluation of a smoking cessation training program for medical residents in an inner-city hospital.

Thirty-four medical residents at a hospital serving a predominantly black inner-city area were trained to counsel their patients to quit smoking. They were tested before the training session and again 4 months later with questionnaires assessing smoking knowledge, attitude, and clinical practice. The training consisted of two 1-hour lectures, printed materials, and a 1.5-hour Objective Simulated Clinical Exam. Most of the residents were males (88.2%), in internal medicine (87.5%), under the age of 35 (79.4%), and foreign-born (76.5%). Asians (44.1%) comprised the largest racial group, followed by whites (29.4%) and blacks (20.6%). The impact of the training was assessed by comparing the pre- and posttests using paired Student's t tests. Overall score increased from 69.3 to 89.1 (P = .0001) out of a maximum of 131. Scores increased significantly for attitudes and beliefs (38 to 52; P = .0001), knowledge (5.3 to 6.6; P = .0001), and usual practices with smoking patients (25 to 30; P = .002). These data provide evidence that training increased the confidence, motivation, and reported practice of these residents in intervening with their patients, the majority of whom are black. This has special significance because physicians are least likely to advise black patients and those in lower socioeconomic groups to quit smoking. The demographic profile of our residents is characteristic of many inner-city hospitals.
