Effects of Diagnostic Work-Up on Medical Decision-Making for Canine Urinary Tract Infection: An Observational Study in Danish Small Animal Practices.

ABSTRACT: Clinical signs of urinary tract disease in dogs often lead to prescription of antibiotics. Appropriate diagnostic work-up could optimize treatment and reduce the risk of inappropriate use of antibiotics.To describe and evaluate the impact of diagnostic work-up on decision to treat (DTT) and choice of antibiotic treatment (COT) for dogs presenting with clinical signs of urinary tract disease.One hundred and fifty-one dogs presenting to 52 Danish veterinary practices.Prospective, observational study. Clinical signs, diagnostic work-up, and prescriptions were recorded. Urine samples were submitted to a reference laboratory for quantitative bacterial culture (QBC) and susceptibility testing. The laboratory results were used as reference for assessing the appropriateness of DTT and COT.In the majority of dogs, veterinarians performed dipstick (99%), microscopic examination of urine (80%) and bacterial culture (56%). Fifty-one percent of dogs had urinary tract infection (UTI) based on reference QBC. Appropriate DTT was made for 62% of the dogs, while 36% were over-prescribed and 2% under-prescribed. Inappropriate use of second-line agents was found in 57% of the UTI cases. Performing microscopy-but not culture-significantly impacted DTT (P?=?0.039) while no difference was seen in COT (P?=?0.67). The accuracy of in-house microscopy and culture were 64.5 and 77%, respectively.Over-prescription of antibiotics was common among dogs with suspected UTI, regardless of the diagnostic work-up performed. Test inaccuracy under practice conditions and incoherence between diagnostic test results and decision-making both explained inappropriate and unnecessary use of antibiotics.

Project description:BackgroundThough urinary incontinence (UI) is a bothersome condition for the individual patient, the patients tend not to inform their physician about UI and the physician tend not to ask the patient. Recently different initiatives have been established in Danish general practices to improve the management of UI. The aim of this study was to identify the handling of urinary incontinence (UI) in Danish general practices after distribution of clinical guidelines and reimbursement for using a UI diary.MethodsIn October 2001, a questionnaire was sent to 243 general practitioners (GPs) in Frederiksborg County following distribution of clinical guidelines in July 1999 (UI in general practice) and September 2001 (UI in female, geriatric, or neurological patients). A policy for a small reimbursement to GPs for use of a fluid intake/voiding diary in the assessment of UI in general practice was implemented in October 2001. Information concerning monthly reimbursement for using a voiding diary, prescribed drugs (presumably used for treating UI), UI consultations in outpatient clinics, and patient reimbursement for pads was obtained from the National Health Service County Registry.ResultsOf the 132 (54%) GPs who replied, 87% had read the guidelines distributed 2 years before, but only 47% used them daily. The majority (69%) of the responding GPs had read and appreciated 1-3 other UI guidelines distributed before the study took place. Eighty-three percent of the responding GPs sometimes or often actively asked their patients about UI, and 92% sometimes or often included a voiding diary in the UI assessment. The available registry data concerning voiding diary reimbursement, prescribed UI drugs, UI consultations in outpatient clinics, and patient reimbursement for pads were insufficient or too variable to determine significant trends.ConclusionGPs management of UI in a Danish county may be reasonable, but low response rate to the questionnaire and insufficient registry data made it difficult to evaluate the impact of different UI initiatives.

Project description:OBJECTIVES:To examine the association between postpartum urinary tract infection and intended mode of delivery as well as actual mode of delivery. DESIGN:Retrospective cohort study. SETTING AND PARTICIPANTS:All live births in Denmark between 2004 and 2010 (n=450?856). Births were classified by intended caesarean delivery (n=45?053) or intended vaginal delivery (n=405?803), and by actual mode of delivery: spontaneous vaginal delivery, operative vaginal delivery, emergency or planned caesarean delivery in labour or prelabour. PRIMARY AND SECONDARY OUTCOME MEASURES:The primary outcome measure was postpartum urinary tract infection (n=16?295) within 30 days post partum, defined as either a diagnosis of urinary tract infection in the National Patient Registry or redemption of urinary tract infection-specific antibiotics recorded in the Register of Medicinal Product Statistics. RESULTS:We found that 4.6% of women with intended caesarean delivery and 3.5% of women with intended vaginal delivery were treated for postpartum urinary tract infection.Women with intended caesarean delivery had a significantly increased risk of postpartum urinary tract infection compared with women with intended vaginal delivery (OR 1.33, 95% CI 1.27 to 1.40), after adjustment for age at delivery, smoking, body mass index, educational level, gestational diabetes mellitus, infection during pregnancy, birth weight, preterm delivery, preterm prelabour rupture of membranes, pre-eclampsia, parity and previous caesarean delivery (adjusted OR 1.24, 95% CI 1.17 to 1.46).Using actual mode of delivery as exposure, all types of operative delivery had an equally increased risk of postpartum urinary tract infection compared with spontaneous vaginal delivery. CONCLUSIONS:Compared with intended vaginal delivery, intended caesarean delivery was significantly associated with a higher risk of postpartum urinary tract infection. Future studies should focus on reducing routine catheterisation prior to operative vaginal delivery as well as improving procedures related to catheterisation.

Project description:BackgroundMost diagnostic tests for acute uncomplicated urinary tract infections (UTIs) have been previously studied in so-called single-test evaluations. In practice, however, clinicians use more than one test in the diagnostic work-up. Since test results carry overlapping information, results from single-test studies may be confounded. The primary objective of the Amsterdam Cystitis/Urinary Tract Infection Study (ACUTIS) is to determine the (additional) diagnostic value of relevant tests from patient history and laboratory investigations, taking into account their mutual dependencies. Consequently, after suitable validation, an easy to use, multivariable diagnostic rule (clinical index) will be derived.MethodsWomen who contact their GP with painful and/or frequent micturition undergo a series of possibly relevant tests, consisting of patient history questions and laboratory investigations. Using urine culture as the reference standard, two multivariable models (diagnostic indices) will be generated: a model which assumes that patients attend the GP surgery and a model based on telephone contact only. Models will be made more robust using the bootstrap. Discrimination will be visualized in high resolution histograms of the posterior UTI probabilities and summarized as 5th, 10th, 25th 50th, 75th, 90th, and 95th centiles of these, Brier score and the area under the receiver operating characteristics curve (ROC) with 95% confidence intervals. Using the regression coefficients of the independent diagnostic indicators, a diagnostic rule will be derived, consisting of an efficient set of tests and their diagnostic values. The course of the presenting complaints is studied using 7-day patient diaries. To learn more about the natural history of UTIs, patients will be offered the opportunity to postpone the use of antibiotics.DiscussionWe expect that our diagnostic rule will allow efficient diagnosis of UTIs, necessitating the collection of diagnostic indicators with proven added value. GPs may use the rule (preferably after suitable validation) to estimate UTI probabilities for women with different combinations of test results. Finally, in a subcohort, an attempt is made to identify which indicators (including antibiotic treatment) are useful to prognosticate recovery from painful and/or frequent micturition.
