Comparing Combination Drop Therapy to a Standard Drop Regimen After Routine Cataract Surgery.

ABSTRACT: Purpose:To evaluate the efficacy of a combined steroid/antibiotic/non-steroidal anti-inflammatory drop relative to a regimen of multiple drops after cataract surgery. Setting:Single clinical practice in the USA. Design:Prospective randomized contralateral eye study. Methods:Subjects presenting for bilateral cataract surgery were enrolled with contralateral eyes randomly assigned to one of the two groups. Test eyes received a combination therapy (prednisolone acetate 1%, gatifloxacin 0.5%, and bromfenac sodium 0.075%) while control eyes received the same medications in separate drops (bromfenac sodium was 0.07%). Subjects were examined 1, 15 and 30 days after surgery. Visual acuities were measured, along with the refraction, intraocular pressure, patient pain and satisfaction, macular thickness and corneal pachymetry. The primary measure of interest was the change in macular thickness from baseline to the 15- and 30-day visits. The frequency and severity of reported ocular adverse events were tabulated for each group and compared. Results:Thirty-three subjects completed the study. Changes in central macular thickness were similar between groups, with only one control eye exhibiting significant macular edema. No differences in visual acuity, corneal edema, cells or flare were observed between groups. There were eight mild adverse events reported for all eyes of all subjects; the difference in the number of eyes experiencing adverse events was not statistically significantly different between groups (p ? 0.05 for all comparisons). While subjective symptoms were similar, all subjects indicated that they preferred the combination drop. Conclusion:A combination drop showed similar efficacy to multiple drops and was overwhelmingly preferred by subjects.

Project description:For surgical interventions classified as clean or clean-contaminated, including laparotomy, guidelines in human and veterinary medicine recommend a short-term perioperative antibiotic prophylaxis (PAP). In equine colic surgery, however, PAP commonly exceeds 24 h. The aim of this study was to compare a single-shot to a 5-day lasting PAP considering surgical site infections (SSI) and other adverse effects probably associated with the particular antimicrobial regimen. The study was designed as a randomised non-inferiority pilot study including horses subjected to colic surgery while receiving one of two distinct PAP regimens. All horses (n = 67) included in the study received the standard physical examination before and after surgery. Colic surgery was performed according to the current standard of the clinic. Horses were randomly assigned to two groups, receiving either the "single-shot" or the "5-day lasting" antibiotic prophylaxis. The "single-shot" group (n = 30) received penicillin and gentamicin only once before and, if needed, during surgery, whereas the "5-day lasting" group (n = 37) received antibiotics for five days. In addition to the standard laboratory examinations, serum amyloid A and fibrinogen were determined preoperatively and during five days after surgery. SSI, postoperative colitis and haemolytic anaemia were classified as postoperative complications potentially related to antibiotic use. The outcome of this preliminary non-inferiority clinical trial showed that the occurrence of postoperative adverse events (i.e., SSI, postoperative colitis and haemolytic anaemia) lacked significant differences between the study groups. Main limitations: The main limitations of this study are the limited group sizes and our inability to blind the study. Single-shot PAP seems to be an alternative approach considering the 5-day lasting protocol commonly used in equine abdominal surgery. However, a proper hygiene management together with a close clinical and laboratory monitoring of the equine patient is indispensable.

Project description:ObjectivesTo compare 90-day postoperative complication rates between Veterans receiving cataract surgery in VA vs Community Care (CC) during the first year of implementation of the Veterans Choice Act.Data sourcesFiscal Year (FY) 2015 VA and CC outpatient data from VA's Corporate Data Warehouse (CDW) 10/01/14-9/30/15). FY14 data were used to obtain baseline clinical information prior to surgery.Study designRetrospective one-year study using secondary data to compare 90-day complication rates following cataract surgery (measured using National Quality Forum (NQF) criteria) in VA vs CC. NQF defines major complications from a specified list of Current Procedural Terminology (CPT) codes. We ran a series of logistic regression models to predict 90-day complication rates, adjusting for Veterans' sociodemographic characteristics, comorbidities, preoperative ocular conditions, eye risk group, and type of cataract surgery (classified as routine vs complex).Data collectionWe linked VA and CC users through patient identifiers obtained from the CDW files. Our sample included all enrolled Veterans who received outpatient cataract surgery either in the VA or through CC during FY15. Cataract surgeries were identified through CPT codes 66 984 (routine) and 66 982 (complex).Principal findingsOf the 83,879 cataract surgeries performed in FY15, 31 percent occurred through CC. Undergoing complex surgery and having a high-risk eye (based on preoperative ocular conditions) were the strongest clinical predictors of 90-day postoperative complications. Overall, we found low complication rates, ranging from 1.1 percent in low-risk eyes to 3.6 percent in high-risk eyes. After adjustment for important confounders (eg, race, rurality, and preoperative ocular conditions), there were no statistically significant differences in 90-day complication rates between Veterans receiving cataract surgery in VA vs CC.ConclusionsAs more Veterans seek care through CC, future studies should continue to monitor quality of care across the two care settings to help inform VA's "make vs buy decisions."
