How to measure quantitative antibiotic use in order to support antimicrobial stewardship in acute care hospitals: a retrospective observational study
A cornerstone of antimicrobial stewardship programs (ASPs) is monitoring quantitative antibiotic use. Frequently used metrics are defined daily dose (DDD) and days of therapy (DOT). The purpose of this study was (1) to explore for the hospital setting the possibilities of quantitative data retrieval on the level of medical specialty and (2) to describe factors affecting the usability and interpretation of these quantitative metrics. We performed a retrospective observational study, measuring overall systemic antibiotic use at specialty level over a 1-year period, from December 1st 2014 to December 1st 2015, in one university and 13 non-university hospitals in the Netherlands. We distinguished surgical and non-surgical adult specialties. The association between DDDs, calculated from aggregated dispensing data, and DOTs, calculated from patient-level prescription data, was explored descriptively and related to organizational factors, data sources (prescription versus dispensing data), data registration, and data extraction. Twelve hospitals were able to extract dispensing data (DDD), three of which on the level of medical specialty; 13 hospitals were able to extract prescription data (DOT), 11 of which by medical specialty. A large variation in quantitative antibiotic use was found between hospitals and the correlation between DDDs and DOTs at specialty level was low. Differences between hospitals related to organizational factors, data sources, data registration, and data extraction procedures likely contributed to the variation in quantitative use and the low correlation between DDDs and DOTs. The differences in healthcare organization, data sources, data registration, and data extraction procedures contributed to the variation in reported quantitative use between hospitals. Uniform registration and extraction procedures are necessary for appropriate measurement and interpretation and benchmarking of quantitative antibiotic use.
Heterogeneity of cost estimates in health economic evaluation research. A systematic review of stress urinary incontinence studies
Introduction and hypothesisThere is increased demand for an international overview of cost estimates and insight into the variation affecting these estimates. Understanding of these costs is useful for cost-effectiveness analysis (CEA) research into new treatment modalities and for clinical guideline development.MethodsA systematic search was conducted in Ovid MEDLINE & other non-indexed materials and Ovid Embase for articles published between 1995 and 2017. The National Health Service Economic Evaluation Database (NHS-EED) filter and the McMaster sensitive therapy filter were combined with a bespoke search strategy for stress urinary incontinence (SUI). We extracted unit cost estimates, assessed variability and methodology, and determined transferability.ResultsWe included 37 studies in this review. Four hundred and eighty-two cost estimates from 13 countries worldwide were extracted. Descriptive analysis shows that hospital stay in gynecology ranged between €82 and €1,292 per day. Costs of gynecological consultation range from €30 in France to €158 in Sweden. In the UK, costs are estimated at €228 per hour. Costs of a tension-free vaginal tape (TVT) device range from €431 in Finland to €994 in Canada. TVT surgery per minute costs €25 in France and €82 in Sweden. Total costs of TVT range from €1,224 in Ireland to €5,809 for inpatient care in France. Variation was explored.ConclusionsHeterogeneity was observed in cost estimates for all units at all levels of health care. CEAs of SUI interventions cannot be interpreted without bias when the base of these analyses—namely costs—cannot be compared and generalized.
Does Probability Guided Hysteroscopy Reduce Costs in Women Investigated for Postmenopausal Bleeding?
Objective. To evaluate whether a model to predict a failed endometrial biopsy in women with postmenopausal bleeding (PMB) and a thickened endometrium can reduce costs without compromising diagnostic accuracy. Design, Setting, and Population. Model based cost-minimization analysis. Methods. A decision analytic model was designed to compare two diagnostic strategies for women with PMB: (I) attempting office endometrial biopsy and performing outpatient hysteroscopy after failed biopsy and (II) predicted probability of a failed endometrial biopsy based on patient characteristics to guide the decision for endometrial biopsy or immediate hysteroscopy. Robustness of assumptions regarding costs was evaluated in sensitivity analyses. Main Outcome Measures. Costs for the different strategies. Results. At different cut-offs for the predicted probability of failure of an endometrial biopsy, strategy I was generally less expensive than strategy II. The costs for strategy I were always € 460; the costs for strategy II varied between € 457 and € 475. At a 65% cut-off, a possible saving of € 3 per woman could be achieved. Conclusions. Individualizing the decision to perform an endometrial biopsy or immediate hysteroscopy in women presenting with postmenopausal bleeding based on patient characteristics does not increase the efficiency of the diagnostic work-up.
A Structured Assessment to Decrease the Amount of Inconclusive Endometrial Biopsies in Women with Postmenopausal Bleeding
Objective. To determine whether structured assessment of outpatient endometrial biopsies decreases the number of inconclusive samples. Design. Retrospective cohort study. Setting. Single hospital pathology laboratory. Population. Endometrial biopsy samples of 66 women with postmenopausal bleeding, collected during the usual diagnostic work-up and assessed as insufficient for a reliable histological diagnosis. Methods. Endometrial biopsy samples were requested from the pathology laboratories. The retrieved samples were systematically reassessed by a single pathologist specialized in gynecology. Main Outcome Measure. Disagreement between initial assessment and conclusion after structured reassessment. Results. We retrieved 36 of 66 endometrial biopsy samples from six different pathology laboratories. Structured reassessment of the retrieved samples by a single pathologist specialized in gynecology did not change the conclusion in 35 of the 36 samples. The remaining sample contained a large amount of endometrial tissue and the diagnosis at reassessment was endometrial hyperplasia without atypia. All other samples contained insufficient material for a reliable diagnosis. Conclusion. A structured reassessment of endometrial biopsies samples, which were classified as inconclusive due to insufficient material, did not change the conclusion. Although it might be helpful for pathologists to have diagnostic criteria for adequacy and/or inadequacy of an endometrial biopsy sample, the gain in efficiency is likely to be small.
Development and validation of a short questionnaire in community acquired pneumonia
Background: A short but sensitive questionnaire evaluating changes in respiratory symptoms and well being during the treatment of community acquired pneumonia (CAP) is needed. We have developed a measurement and evaluated its psychometric properties in 67 patients admitted with CAP. Methods: The patients were asked to indicate the presence and severity of dyspnoea, coughing, coughing up sputum, coughing up sputum with ease, the colour of the sputum, fatigue, fitness, and their state of health. The item fatigue showed substantial overlap with fitness and was therefore excluded. The response of the patients to the remaining eight items was used to calculate a CAP score. Results: The percentage of missing data (0.2–1.7%), floor and ceiling effects (0.2/5.5%), internal consistency (Cronbach α = 0.87), and the intraclass correlation coefficient for test-retest reproducibility (0.83) met predefined criteria, indicating good acceptability and reliability. Face and clinical validity were satisfactory. Effect sizes under treatment were large, indicating high responsiveness. Conclusion: The newly developed CAP score is a simple, reliable, valid, and highly responsive instrument. This makes it scientifically sound and clinically relevant for measuring outcome when evaluating treatment strategies in CAP.
Patients with moderate-to-severe plaque psoriasis preferred oral therapies to phototherapies: a preference assessment based on clinical scenarios with trade-off questions
The importance of validly identifying and incorporating patients' views for improving health care is generally acknowledged. Common approaches to assess patients' preferences are based on the quality adjusted life year (QALY) framework, but this ignores a number of aspects that may be relevant. As an alternative, we assessed patients' treatment preferences and trade-offs for five common systemic therapies for psoriasis. Twenty-nine patients with moderate-to-severe psoriasis expressed treatment preferences for five oral and phototherapies and indicated the relative importance of various treatment attributes, such as adverse effects, discomforts, and safety measures. In a structured interview, they were presented with clinical scenarios that contained descriptions of process and outcome characteristics and illustrations of the anticipated treatment benefit. Over all paired comparisons, methotrexate (33%), cyclosporin (30%), acitretin (15%), UV-B (14%), and PUVA (8%) were preferred to the other treatment. Patients were willing to trade-off their initial preference for more improvement of psoriasis. Psoriasis patients generally prefer oral to phototherapies and consider most adverse effects and several discomforts important for selecting treatment. Our scenario-based structured interview approach to treatment preferences allowed us to incorporate a broad spectrum of potentially relevant decision components in a clinically meaningful way.
Methotrexate versus Cyclosporine in Moderate-to-Severe Chronic Plaque Psoriasis
Although methotrexate and cyclosporine are both effective treatments for psoriasis, their comparative efficacy has not been established. This trial compared the two drugs and found them to be similarly effective. Each was associated with specific but limited side effects. The two drugs are similarly effective in moderate-to-severe psoriasis. Chronic plaque psoriasis is a skin disease characterized by sharply demarcated, erythematous, squamous lesions, with an estimated worldwide prevalence of 0.1 to 3 percent. 1 Various therapies are available for the treatment of psoriasis, including topical ointments, such as calcipotriene, corticosteroids, tar, and anthralin; phototherapy with ultraviolet B radiation (UVB) and methoxsalen (psoralen) with ultraviolet A radiation (PUVA); systemic drugs such as acitretin; and the systemic immunosuppressant drugs methotrexate and cyclosporine. 2 , 3 Methotrexate and cyclosporine are often used in daily clinical practice, but which of the two is more effective has not been established. The current management of severe psoriasis is . . .
Laparoscopic peritoneal lavage or sigmoidectomy for perforated diverticulitis with purulent peritonitis: a multicentre, parallel-group, randomised, open-label trial
Case series suggest that laparoscopic peritoneal lavage might be a promising alternative to sigmoidectomy in patients with perforated diverticulitis. We aimed to assess the superiority of laparoscopic lavage compared with sigmoidectomy in patients with purulent perforated diverticulitis, with respect to overall long-term morbidity and mortality. We did a multicentre, parallel-group, randomised, open-label trial in 34 teaching hospitals and eight academic hospitals in Belgium, Italy, and the Netherlands (the Ladies trial). The Ladies trial is split into two groups: the LOLA group comparing laparoscopic lavage with sigmoidectomy and the DIVA group comparing Hartmann's procedure with sigmoidectomy plus primary anastomosis. The DIVA section of this trial is still underway but here we report the results of the LOLA section. Patients with purulent perforated diverticulitis were enrolled for LOLA, excluding patients with faecal peritonitis, aged older than 85 years, with high-dose steroid use (≥20 mg daily), and haemodynamic instability. Patients were randomly assigned (2:1:1; stratified by age [<60 years vs ≥60 years]) using secure online computer randomisation to laparoscopic lavage, Hartmann's procedure, or primary anastomosis in a parallel design after diagnostic laparoscopy. Patients were analysed according to a modified intention-to-treat principle and were followed up after the index operation at least once in the outpatient setting and after sigmoidoscopy and stoma reversal, according to local protocols. The primary endpoint was a composite endpoint of major morbidity and mortality within 12 months. This trial is registered with ClinicalTrials.gov, number NCT01317485. Between July 1, 2010, and Feb 22, 2013, 90 patients were randomly assigned in the LOLA section of the Ladies trial when the study was terminated by the data and safety monitoring board because of an increased event rate in the lavage group. Two patients were excluded for protocol violations. The primary endpoint occurred in 30 (67%) of 45 patients in the lavage group and 25 (60%) of 42 patients in the sigmoidectomy group (odds ratio 1·28, 95% CI 0·54–3·03, p=0·58). By 12 months, four patients had died after lavage and six patients had died after sigmoidectomy (p=0·43). Laparoscopic lavage is not superior to sigmoidectomy for the treatment of purulent perforated diverticulitis. Netherlands Organisation for Health Research and Development.
The relation between age, time since menopause, and endometrial cancer in women with postmenopausal bleeding
The objective is to assess among women with postmenopausal bleeding the relationship of age and time since menopause on one hand and the presence of endometrial cancer and atypical hyperplasia on the other hand. In a multicenter prospective cohort study, 614 women presenting with postmenopausal bleeding were included. Women underwent transvaginal sonography and, in cases where the endometrial thickness was >4 mm, endometrial sampling. Splines were used to assess the association between each of the continuous variables and (pre)malignancy of the endometrium. Subsequently, univariate and multivariate analysis were performed. The average age for women without (pre)malignancy was 61.7 years (SD 9.8). As malignant and premalignant cases were found to have similar age, these subgroups were merged in the analyses. Age was an independent predictor of (pre)malignancy. In women younger than 55 years, the odds ratio was 1.9 (95% CI: 1.1–3.3) for each year under 55 years of age and 1.03 (95% CI: 1.00–1.06) for each year over 55 years of age. The risk of (pre)malignancy of the endometrium was 4.9% in women less than 3 years postmenopausal versus 19.7% in women more than 20 years postmenopausal. However, in a multivariate analysis only age contributed to the prediction of risk. This study demonstrates that, in postmenopausal women with vaginal bleeding, the risk of (pre)malignancy of the endometrium is low in women under 50 years of age, increases considerably until 55 years of age, and rises only modestly with further advancing age. Future studies should explore whether these findings can be incorporated in the diagnostic work-up of women with postmenopausal bleeding.
Laparoscopic peritoneal lavage versus sigmoidectomy for perforated diverticulitis with purulent peritonitis: three-year follow-up of the randomised LOLA trial
BackgroundThis study aimed to compare laparoscopic lavage and sigmoidectomy as treatment for perforated diverticulitis with purulent peritonitis during a 36 month follow-up of the LOLA trial.MethodsWithin the LOLA arm of the international, multicentre LADIES trial, patients with perforated diverticulitis with purulent peritonitis were randomised between laparoscopic lavage and sigmoidectomy. Outcomes were collected up to 36 months. The primary outcome of the present study was cumulative morbidity and mortality. Secondary outcomes included reoperations (including stoma reversals), stoma rates, and sigmoidectomy rates in the lavage group.ResultsLong-term follow-up was recorded in 77 of the 88 originally included patients, 39 were randomised to sigmoidectomy (51%) and 38 to laparoscopic lavage (49%). After 36 months, overall cumulative morbidity (sigmoidectomy 28/39 (72%) versus lavage 32/38 (84%), p = 0·272) and mortality (sigmoidectomy 7/39 (18%) versus lavage 6/38 (16%), p = 1·000) did not differ. The number of patients who underwent a reoperation was significantly lower for lavage compared to sigmoidectomy (sigmoidectomy 27/39 (69%) versus lavage 17/38 (45%), p = 0·039). After 36 months, patients alive with stoma in situ was lower in the lavage group (proportion calculated from the Kaplan–Meier life table, sigmoidectomy 17% vs lavage 11%, log-rank p = 0·0268). Eventually, 17 of 38 (45%) patients allocated to lavage underwent sigmoidectomy.ConclusionLong-term outcomes showed that laparoscopic lavage was associated with less patients who underwent reoperations and lower stoma rates in patients alive after 36 months compared to sigmoidectomy. No differences were found in terms of cumulative morbidity or mortality. Patient selection should be improved to reduce risk for short-term complications after which lavage could still be a valuable treatment option.
