Routine use of the Pneumonia Severity Index for guiding the site-of-treatment decision of patients with pneumonia in the emergency department: a multicenter, prospective, observational, controlled cohort study.

BACKGROUND: Although the Pneumonia Severity Index (PSI) has been extensively validated, little is known of the impact of its routine use as an aid to site-of-treatment decisions for patients with pneumonia who present to emergency departments (EDs). METHODS: A prospective, observational, controlled cohort study of patients with pneumonia was conducted in 8 EDs that used the PSI (PSI-user EDs) and 8 EDs that did not use the PSI (PSI-nonuser EDs) in France. The outcomes examined included the proportion of "low-risk" patients (PSI risk classes I-III) treated as outpatients, all-cause 28-day mortality, admission of inpatients to the intensive care unit, and subsequent hospitalization of outpatients. RESULTS: Of the 925 patients enrolled in the study, 472 (51.0%) were treated at PSI-user EDs, and 453 (49.0%) were treated at PSI-nonuser EDs; 449 (48.5%) of all patients were considered to be at low risk. In PSI-user EDs, 92 (42.8%) of 215 patients at low risk were treated as outpatients, compared with 56 (23.9%) of 234 patients at low risk in PSI-nonuser EDs. The adjusted odds ratios for outpatient treatment were higher for patients in PSI risk classes I and II who were treated in PSI-user EDs, compared with PSI-nonuser EDs (adjusted odds ratio, 7.0 [95% confidence interval, 2.0-25.0] and 4.6 [95% confidence interval, 1.3-16.2], respectively), whereas the adjusted odds ratio did not differ by PSI-user status among patients in risk class III or among patients at high risk. After adjusting for pneumonia severity, mortality was lower in patients who were treated in PSI-user EDs; other safety outcomes did not differ between patients treated in PSI-user and PSI-nonuser EDs. CONCLUSIONS: The routine use of the PSI was associated with a larger proportion of patients in PSI risk classes I and II who had pneumonia and who were treated in the outpatient environment without compromising their safety.

Effectiveness of a guideline for venous thromboembolism prophylaxis in elderly post-acute care patients: a multicenter study with systematic ultrasonographic examination.

BACKGROUND: Thromboprophylaxis in elderly patients, including post-acute care patients, is at variance with scientific evidence. The purpose of this study was to determine whether a multifaceted intervention was followed by a decrease in deep venous thrombosis (DVT). METHODS: A prospective preintervention-postintervention study was conducted in 1373 patients (preintervention phase, n = 709; postintervention phase, n = 664), aged 65 years or older, enrolled in 33 hospital-based post-acute care facilities in France. An evidence-based guideline addressing pharmacologic and mechanical prophylaxis was implemented through a multifaceted intervention. The main outcome measure was any DVT diagnosed at routine comprehensive ultrasonography performed by registered angiologists. RESULTS: A DVT was found in 91 patients (12.8%) in the preintervention phase and in 52 patients (7.8%) in the postintervention phase (P = .002). The decrease in DVT involved the calf (7.1% vs 3.6%; P = .005) and the proximal venous segments (5.8% vs 4.2%; P = .18) and remained significant after adjusting for risk factors (adjusted odds ratio of any DVT, 0.58; 95% confidence interval, 0.39-0.86). Pharmacologic prophylaxis with either low-molecular-weight heparin at the high-risk dose, unfractionated heparin, and vitamin K antagonist was similar in the 2 study groups, whereas patients in the postintervention group were more likely to use graduated compression stockings (27.4% vs 34.6%; P = .004) and less likely to receive low-molecular-weight heparin at the low-risk dose (24.7% vs 18.5%; P = .006), which was not recommended by our guideline. CONCLUSIONS: A multifaceted intervention addressing venous thromboembolism prophylaxis in post-acute care patients can be followed by a significant decrease in the rate of any DVT in elderly patients. More active interventions are needed to enforce compliance with evidence-based guidelines.

Brief report: graduated compression stocking thromboprophylaxis for elderly inpatients: a propensity analysis.

BACKGROUND: Graduated compression stockings (GCS) are often used for deep vein thrombosis prophylaxis in nonsurgical patients, although evidence on their effectiveness is lacking in this setting. OBJECTIVE: To determine whether prophylaxis with GCS is associated with a decrease in the rate of deep vein thrombosis in nonsurgical elderly patients. METHODS: Using original data from 2 multicenter nonrandomized studies, we performed multivariable and propensity score analyses to determine whether prophylaxis with GCS reduced the rate of deep vein thrombosis among 1,310 postacute care patients 65 years or older. The primary outcome was proximal deep vein thrombosis detected by routine compression ultrasonography performed by registered vascular physicians. RESULTS: Proximal deep vein thrombosis was found in 5.7% (21/371) of the GCS users and in 5.2% (49/939) of the GCS nonusers (odds ratio [OR], 1.09; 95% confidence interval [CI], 0.64-1.84). Although adjusting for propensity score eliminated all differences in baseline characteristics between users and nonusers, the OR for proximal deep vein thrombosis associated with GCS remained nonsignificant in propensity-stratified (adjusted OR, 1.11; 95% CI, 0.59-2.10) and propensity-matched (conditional OR, 0.92; 95% CI, 0.42-2.02) analysis. Similar figures were observed for distal and any deep vein thrombosis. The rates of deep vein thrombosis did not differ according to the length of stockings. CONCLUSIONS: Prophylaxis with GCS is not associated with a lower rate of deep vein thrombosis in nonsurgical elderly patients in routine practice. Randomized studies are needed to assess the efficacy of GCS when properly used in this setting.

Perception and use of the results of patient satisfaction surveys by care providers in a French teaching hospital.

OBJECTIVE: . The aim of this study was to assess clinical staff's opinions on the results of in-patient satisfaction surveys and their use within the quality improvement process. SETTING: The institution is a 2200-bed teaching hospital of tertiary health care employing 8000 professionals. Patient satisfaction surveys are carried out each year using a validated questionnaire mailed to a random sample of patients. The specific results of each department are sent to the medical and paramedical managers. METHODS: We conducted a questionnaire survey on 500 care providers randomly selected in every medical and surgical department. RESULTS: A total of 261 questionnaires were returned and analysed. Overall, 94% of responders had a favourable opinion of the patient satisfaction surveys. They considered that the patient was able to judge hospital service quality, especially in its relational, organizational, and environmental dimensions. The specific results for the department were less well known than the overall hospital results (60 versus 76%). These results were formally discussed in the department according to 40% of responders; 40% declared that these data resulted in improvement actions and considered that they led to modifications in their behaviour with patients. CONCLUSIONS: Despite a declared interest in satisfaction surveys, the results remain underused by hospital staff and insufficiently discussed within teams.

Factors associated with the hospitalization of low-risk patients with community-acquired pneumonia in a cluster-randomized trial.

BACKGROUND: Many low-risk patients with pneumonia are hospitalized despite recommendations to treat such patients in the outpatient setting. OBJECTIVE: To identify the factors associated with the hospitalization of low-risk patients with pneumonia. METHODS: We analyzed data collected by retrospective chart review for 1,889 low-risk patients (Pneumonia Severity Index [PSI] risk classes I to III without evidence of arterial oxygen desaturation) enrolled in a cluster-randomized trial conducted in 32 emergency departments. RESULTS: Overall, 845 (44.7%) of all low-risk patients were treated as inpatients. Factors independently associated with an increased odds of hospitalization included PSI risk classes II and III, the presence of medical or psychosocial contraindications to outpatient treatment, comorbid conditions that were not contained in the PSI (cognitive impairment, history of coronary artery disease, diabetes mellitus, or pulmonary disease), multilobar radiographic infiltrates, and home therapy with oxygen, corticosteroids, or antibiotics before presentation. While 32.8% of low-risk inpatients had a contraindication to outpatient treatment and 47.1% had one or more preexisting treatments, comorbid conditions, or radiographic abnormalities not contained in the PSI, 20.1% had no identifiable risk factors for hospitalization other than PSI risk class II or III. CONCLUSIONS: Hospital admission appears justified for one-third of low-risk inpatients based upon the presence of one or more contraindications to outpatient treatment. At least one-fifth of low-risk inpatients did not have a contraindication to outpatient treatment or an identifiable risk factor for hospitalization, suggesting that treatment of a larger proportion of such low-risk patients in the outpatient setting could be achieved without adversely affecting patient outcomes.

Efficacy of breastfeeding support provided by trained clinicians during an early, routine, preventive visit: a prospective, randomized, open trial of 226 mother-infant pairs.

BACKGROUND: Despite growing evidence of the benefits of prolonged breastfeeding for mother and infant health, the rate of breastfeeding at infant age of 6 months remains below the Healthy People 2010 goal. The greatest decrease in the breastfeeding rate occurs during the first 4 postpartum weeks. Mothers who discontinue breastfeeding early are more likely to report lack of confidence in their ability to breastfeed, problems with the infant latching or suckling, and lack of individualized encouragement from their clinicians in the early postdischarge period. Observational studies suggest that primary care physicians can increase breastfeeding rates through specific advice and practices during routine preventive visits. However, robust scientific evidence based on randomized, controlled trials is currently lacking. OBJECTIVE: The purpose of this study was to determine whether attending an early, routine, preventive, outpatient visit delivered in a primary care physician's office would improve breastfeeding outcomes. DESIGN: The study was a prospective, randomized, parallel-group, open trial. SETTING: Participants were recruited at a level 3 maternity facility, with an average of 2000 births per year, in France. PARTICIPANTS: A total of 231 mothers who had delivered a healthy singleton infant (gestational age: > or =37 completed weeks) and were breastfeeding on the day of discharge were recruited and randomized (116 were assigned to the intervention group and 115 to the control group) between October 1, 2001, and May 31, 2002; 226 mother-infant pairs (112 in the intervention group and 114 in the control group) contributed data on outcomes. INTERVENTION: Support for breastfeeding in the control group included the usual verbal encouragement provided by the maternity ward staff members, a general health assessment and an evaluation for evidence of successful breastfeeding behavior by the pediatrician working in the obstetrics department on the day of discharge, provision of the telephone number of a peer support group, mandatory routine, preventive, outpatient visits at 1, 2, 3, 4, 5, and 6 months of infant age, and 10 weeks of paid maternity leave (extended to 18 weeks after the birth of the third child). In addition to the usual predischarge and postdischarge support, the mothers in the intervention group were invited to attend an individual, routine, preventive, outpatient visit in the office of 1 of the 17 participating primary care physicians (pediatricians or family physicians) within 2 weeks after the birth. The participating physicians received a 5-hour training program on breastfeeding, delivered in 2 parts in 1 month, before the beginning of the study. OUTCOME MEASURES: The primary outcome was the prevalence of exclusive breastfeeding reported at 4 weeks (defined as giving maternal milk as the only food source, with no other foods or liquids, other than vitamins or medications, being given). The secondary outcomes included any breastfeeding reported at 4 weeks, breastfeeding duration, breastfeeding difficulties, and satisfaction with breastfeeding experiences. Classification into breastfeeding categories reported at 4 weeks was based on 24-hour dietary recall. RESULTS: Ninety-two mothers (79.3%) assigned to the intervention group and 8 mothers (7.0%) assigned to the control group reported that they had attended the routine, preventive, outpatient visit in the office of 1 of the 17 primary care physicians participating in the study. Mothers in the intervention group were more likely to report exclusive breastfeeding at 4 weeks (83.9% vs 71.9%; hazard ratio: 1.17; 95% confidence interval [CI]: 1.01-1.34) and longer breastfeeding duration (median: 18 weeks vs 13 weeks; hazard ratio: 1.40; 95% CI: 1.03-1.92). They were less likely to report any breastfeeding difficulties (55.3% vs 72.8%; hazard ratio: 0.76; 95% CI: 0.62-0.93). There was no significant difference between the 2 groups with respect to the rate of any breastfeeding at 4 weeks (89.3% vs 81.6%; hazard ratio: 1.09; 95% CI: 0.98-1.22) and the rate of mothers fairly or very satisfied with their breastfeeding experiences (91.1% vs 87.7%; hazard ratio: 1.04; 95% CI: 0.95-1.14). CONCLUSIONS: Although we cannot exclude the possibility that findings might differ in other health care systems, this study provides preliminary evidence of the efficacy of breastfeeding support through an early, routine, preventive visit in the offices of trained primary care physicians. Our findings also suggest that a short training program for practicing physicians might contribute to improving breastfeeding outcomes. Multifaceted interventions aiming to support breastfeeding should involve primary care physicians.

Effect of a training program for maternity ward professionals on duration of breastfeeding.

BACKGROUND: Training programs are commonly viewed as an effective way to improve breastfeeding-related practices of health professionals. The objective of this study was to determine whether a 3-day training program for maternity ward professionals was followed by an increase in duration of any breastfeeding. METHODS: A before-and-after study was conducted involving two retrospective random samples of 308 mothers who had delivered a healthy singleton infant of 37 weeks' or more gestation and 2,500 g or more birthweight in a level 3 maternity ward in a university hospital in France. Data were gathered from medical records and postal questionnaire. RESULTS: Study participants included 169 mothers (54.9%) in the pre-intervention sample and 178 (57.8%) in the post-intervention sample. The prevalence of any breastfeeding at birth was 77.5 percent (70.5%-83.6%) in the pre-intervention sample and 82.6 percent (76.2%-87.8%) in the post-intervention sample(p=0.24); the median duration of any breastfeeding was 13 weeks and 16 weeks, respectively(chi2 log-rank test=5.8, p=0.02). The decreased risk of weaning in the post-intervention sample persisted after adjustment for baseline characteristics (adjusted hazard ratio=0.70 [0.54-0.91]). It was paralleled by significant improvement in maternity ward practices that are known to affect the duration of breastfeeding. CONCLUSION: An intensive 3-day training program for maternity ward professionals can be followed by a significant but moderate increase in the duration of any breastfeeding. Multifaceted interventions involving prenatal components and community support should be planned in Western countries with low to intermediate prevalence of breastfeeding.

Deep vein thrombosis in elderly patients hospitalized in subacute care facilities: a multicenter cross-sectional study of risk factors, prophylaxis, and prevalence.

BACKGROUND: The efficacy of venous thromboembolism prophylaxis has not been established, to our knowledge, in elderly patients hospitalized in subacute care facilities. OBJECTIVES: To describe risk factors and physician practices in the prevention of venous thromboembolism and to estimate the prevalence of deep vein thrombosis. METHODS: A multicenter cross-sectional study was conducted in the subacute care departments of 36 French hospitals. The study population included 852 inpatients older than 64 years. Systematic ultrasound examination was performed by angiologists. RESULTS: Of the 852 inpatients, 178 (20.9%; 95% confidence interval [CI], 18.2%-23.8%) had 3 or more risk factors other than age, while 144 patients (16.9%; 95% CI, 14.4%-19.6%) had none. The rate of prophylactic anticoagulant treatment was 56.1%, ranging from 20.0% to 86.9%, depending on the department. In multivariate analysis, prophylaxis use was associated with acute immobilization (odds ratio [OR], 4.17; 95% CI, 2.48-7.01), chronic immobilization (OR, 3.19; 95% CI, 2.22-4.60), major surgical procedure (OR, 6.81; 95% CI, 4.26-10.88), and congestive heart failure (OR, 1.65; 95% CI, 1.02-2.67). Prophylaxis use was low in patients who had cancer (OR, 0.49; 95% CI, 0.29-0.84) or myocardial infarction (OR, 0.39; 95% CI, 0.14-1.00). It was not significantly associated with paralytic stroke or history of venous thromboembolism. Deep vein thrombosis was detected in 135 patients (15.8%; 95% CI, 13.4%-18.5%): 50 (5.9%; 95% CI, 4.4%-7.7%) had proximal vein thrombosis and 85 (10.0%; 95% CI, 8.0%-12.2%) had calf vein thrombosis. CONCLUSIONS: The prevalence of deep venous thrombosis is high in these patients, despite wide use of prophylaxis. Further prospective studies assessing the clinical benefit of extended duration prophylaxis are needed in elderly patients hospitalized in subacute care settings.

Assessment of a structured in-hospital educational intervention addressing breastfeeding: a prospective randomised open trial.

OBJECTIVE: To determine whether a single one-to-one in-hospital education session could increase the rate of breastfeeding at 17 weeks. DESIGN: A prospective, randomised, parallel group, open trial. SETTING: A level two maternity hospital in France. SAMPLE: Breastfeeding mothers who were employed outside the home prenatally and were delivered of a healthy singleton. INTERVENTION: A structured one-to-one in-hospital education session. METHODS: One hundred and six mother-infant pairs were allocated to the intervention group and 104 to the control group (receiving usual verbal encouragement). A total of 93 mother-infant pairs in the intervention group and 97 in the control group provided complete data for final evaluation of efficacy. MAIN OUTCOME MEASURE: Rate of breastfeeding at infant age of 17 weeks. RESULTS: There was no significant difference between the two groups in the rate of any breastfeeding (34.4% in the intervention group vs 40.2% in the control group, relative risk = 0.86 [0.52-1.40]), and in the rate of exclusive breastfeeding (14.0% in the intervention group vs 14.4% in the control group, relative risk = 0.97 [0.42-2.22]). CONCLUSION: Our findings suggest that a single in-hospital educational intervention has no effect on the breastfeeding rate at four months. Guidance provided by maternity staff should be reinforced by a long term multifaceted support programme in countries with a low to intermediate rate of breastfeeding.

Determining indications for care common to competing guidelines by using classification tree analysis: application to the prevention of venous thromboembolism in medical inpatients.

BACKGROUND: Substantial variations have been reported in the advice given by competing guidelines addressing the same clinical problem. OBJECTIVE: This study aimed to assess the usefulness of classification tree analysis in comparing competing guidelines. METHOD: The authors implemented a classification tree-growing algorithm on cross-sectional data from 818 patients to determine indications for prophylactic heparin treatment common to 4 competing guidelines disseminated between 1998 and 2000 and addressing the prophylaxis of venous thromboembolism in medical inpatients. RESULTS: The resulting classification tree involved 10 terminal nodes. Its mean accuracy estimated by performing 10-fold cross-validation was 82% (s=3). The guidelines consistently supported prophylactic heparin treatment for 5 indications: a previous episode of deep vein thrombosis or pulmonary embolism, recent paralysis of lower limb(s), congestive heart failure with one or more risk factors, recent myocardial infarction, and malignancy with one or more risk factors. These indications involved 257 patients (31.4%) and were supported by robust scientific evidence. Deep vein thrombosis was detected in 27 of these patients (10.5%). Two consistent negative indications involved 347 patients (42.4%). Deep vein thrombosis was detected in 9 of these patients (2.6%). Three indications involving 214 patients (26.2%) were discordant over the 4 guidelines. CONCLUSION: Classification tree analysis of real patient data is a useful strategy to identify indications common to competing guidelines. These indications should be considered for inclusion when updating guidelines. The findings of recently completed randomized trials have partly resolved the disagreement among the 4 guidelines. This approach may be helpful when developing new guidelines or for identifying topics warranting further complementary clinical trials.
