The 2018 Chitranjan S. Ranawat, MD Award: Developing and Implementing a Novel Institutional Guideline Strategy Reduced Postoperative Opioid Prescribing After TKA and THA.

BACKGROUND: Opioid prescription management is challenging for orthopaedic surgeons, and we lack evidence-based guidelines for responsible opioid prescribing. Our institution recently developed opioid prescription guidelines for patients undergoing several common orthopaedic procedures including TKA and THA in an effort to reduce and standardize prescribing patterns. QUESTIONS/PURPOSES: (1) How do opioid prescriptions at discharge and 30-day refill rates change in opioid-naïve patients undergoing primary TKA and THA before and after implementation of a novel prescribing guideline strategy? (2) What patient, surgical, and in-hospital factors influence opioid prescription quantity and refill rate? METHODS: New institutional guidelines for patients undergoing TKA and THA recommend a maximum postoperative prescription of 400 oral morphine equivalents (OME), comparable to 50 tablets of 5 mg oxycodone or 80 tablets of 50 mg tramadol. All opioid-naïve patients, defined as those who did not take any opioids within 90 days preceding surgery, undergoing primary TKA and THA at a single tertiary care institution were evaluated from program initiation on August 1, 2017, through December 31, 2017, as the postguideline era cohort. This group (n = 751 patients) was compared with all opioid-naïve patients undergoing TKA and THA from 2016 at the same institution (n = 1822 patients). Some providers were early adopters of the guidelines as they were being developed, which is why January to July 2017 was not evaluated. Patients in the preguideline and postguideline eras were not different in terms of age, sex, race, body mass index, education level, employment status, psychiatric illness, marital status, smoking history, outpatient use of benzodiazepines or gabapentinoids, or diagnoses of diabetes mellitus, peripheral neuropathy, or cancer. The primary outcome assessed was adherence to the new guidelines with a secondary outcome of opioid medication refills ordered within 30 days from any provider. Multivariable logistic regression analyses were performed with outcomes of guideline compliance and refills and adjusted for demographic, surgical, and patient care factors. Patients were followed for 30 days after surgery and no patients were lost to followup. RESULTS: Median opioid prescription and range of prescriptions decreased in the postguideline era compared with the preguideline era (750 OME, interquartile range [IQR] 575-900 OME versus 388 OME, IQR 350-389; difference of medians = 362 OME; p < 0.001). There was no difference among patients undergoing TKA before and after guideline implementation in terms of the 30-day refill rate (35% [349 of 1011] versus 35% [141 of 399]; p = 0.77); this relationship was similar among patient undergoing THA (16% [129 of 811] versus 17% [61 of 352]; p = 0.55). After controlling for relevant patient-level factors, we found that implementation of an institutional guideline was the strongest factor associated with a prescription of ≤ 400 OME (adjusted odds ratio, 36; 95% confidence interval, 25-52; p < 0.001); although a number of patient-level factors also were associated with prescription quantity, the effect sizes were much smaller. CONCLUSIONS: This study provides a proof of concept that institutional guidelines to reduce postoperative opioid prescribing can improve aftercare in patients undergoing arthroplasty in a short period of time. The current report evaluates our experience with the first 5 months of this program; therefore, longer term data will be mandatory to determine longitudinal guideline adherence and whether the cutoffs established by this pilot initiative require further refinement for individual procedures. LEVEL OF EVIDENCE: Level II, therapeutic study.

Vision-related quality of life before and after keratoplasty for Fuchs' endothelial dystrophy.

PURPOSE: To assess vision-related quality of life in Fuchs' dystrophy and changes in vision-related quality of life after 3 types of keratoplasty (penetrating keratoplasty [PK], deep lamellar endothelial keratoplasty [DLEK], and Descemet stripping endothelial keratoplasty [DSEK]). DESIGN: Prospective, observational case series. PARTICIPANTS: Sixty-three subjects with Fuchs' endothelial dystrophy: 12 subjects (12 eyes) received PK, 11 subjects (11 eyes) received DLEK, and 40 subjects (40 eyes) received DSEK. METHODS: Subjects were examined before keratoplasty and at regular intervals through 3 years after keratoplasty. At each examination, vision-related quality of life was assessed using the 25-item National Eye Institute Visual Functioning Questionnaire; best spectacle-corrected and uncorrected visual acuities were measured by using the electronic Early Treatment of Diabetic Retinopathy Study protocol; keratometric cylinder was measured by a manual keratometer. Disability glare was measured with a straylight meter. MAIN OUTCOME MEASURES: Vision-related quality of life composite score. RESULTS: Vision-related quality of life composite score for all eyes with Fuchs' dystrophy before keratoplasty was 72 ± 11 (n = 63) and did not differ between groups (P = 0.88). Vision-related quality of life improved by 6 months (PK, P = 0.008; DLEK, P = 0.03; DSEK, P < 0.001), with continued improvement between 6 months and 3 years after PK (P = 0.01) and DSEK (P = 0.004). At 6 months, the composite score was higher after DSEK than after PK (P = 0.006). At 3 years, there were no differences in composite scores between the 3 treatments (P = 0.33; mean minimum detectable difference, 8 [α = 0.05; ß = 0.20]). After keratoplasty, quality of life was correlated with uncorrected visual acuity at 1 year (r = -0.38; P = 0.001) and at 3 years (r = -0.36; P = 0.02), with disability glare at 3 years (r = -0.41; P = 0.02), and with best-corrected visual acuity at 6 months (r = -0.34; P = 0.03), but not thereafter. CONCLUSIONS: Vision-related quality of life in patients with Fuchs' endothelial dystrophy is significantly impaired but improves after keratoplasty, irrespective of the technique. The improvement is faster after DSEK than after PK, and this might be explained in part by rapid improvement in uncorrected visual acuity after DSEK. This study affirms an advantage of endothelial keratoplasty over PK with respect to patient-reported outcomes.

Novel Single-Needle Approach for Retrocrural Celiac Plexus Blockade Using Fluoroscopic Guidance: A Case Report.

Celiac plexus neurolysis has been shown to be an effective analgesic option for patients with visceral pain related to intraabdominal malignancies. In the setting of significant tumor burden, the celiac plexus may be inaccessible, limiting the efficacy of the transcrural approach. This case report describes a novel single-needle approach to retrocrural celiac plexus blockade, allowing for rapid blockade with a needle trajectory contralateral to the aorta in a 73-year-old woman with altered anatomy secondary to advanced metastatic colorectal cancer.
