Background:Increasing attention has been focused on low-value healthcare services. Through Choosing Wisely campaigns, routine laboratory testing before low-risk surgery has been discouraged in the absence of clinical indications. The authors investigated rates, determinants, and institutional variation in laboratory testing before low-risk procedures. Methods:Patients who underwent ophthalmologic surgeries or predefined low-risk surgeries in Ontario, Canada, between April 1, 2008, and March 31… 
Influence of Institution-Based Factors on Preoperative Blood Testing Prior to Low-Risk Surgery: A Bayesian Generalized Linear Mixed Approach
TLDR
It is indicated that preoperative blood tests are strongly influenced by institutional factors, suggesting that specific guidelines should be developed to avoid excessive preoperative testing for low-risk surgery.
Preoperative pulmonary function tests before low-risk surgery in Japan: a retrospective cohort study using a claims database
TLDR
The authors' analysis found that preoperative PFTs were performed before 72% of low-risk surgeries under general anesthesia and were associated with older age, number of beds at a medical facility, and inpatient procedures.
Preoperative Blood Tests Conducted Before Low-Risk Surgery in Japan: A Retrospective Observational Study Using a Nationwide Insurance Claims Database
TLDR
Preoperative blood tests were performed before 59.5% of low-risk surgeries in Japan and were associated with the type of anesthesia, patient characteristics, and medical facility status.
Prevalence and Factors Associated With Low-Value Preoperative Testing for Patients Undergoing Carpal Tunnel Release at an Academic Medical Center
TLDR
Low-value preoperative tests were frequently received by patients undergoing CTR and were associated with anesthesia type, age, and number of comorbidities, which can help guide efforts to improve the quality and value of surgery for carpal tunnel syndrome and facilitate the development of strategies to reduce LVT.
Use of preoperative haemostasis and ABO blood typing tests in children: a retrospective observational study using a nationwide claims database in Japan
TLDR
In the largest Japanese cohort reported to date, preoperative haemostasis and ABO blood typing tests were performed in a majority of children prior to common paediatric surgeries, and were associated with anaesthesia, surgical type and surgical setting.
Routine perioperative practices and postoperative outcomes for elective lumbar laminectomies.
TLDR
Hospital policies should be re-evaluated to address the overuse of unnecessary preoperative investigations for elective lumbar laminectomies, which have low perioperative transfusion and complication rates.
Prevalence and Cost of Care Cascades After Low-Value Preoperative Electrocardiogram for Cataract Surgery in Fee-for-Service Medicare Beneficiaries.
TLDR
Care cascades after preoperative EKG for cataract surgery are infrequent but costly, and policy and practice interventions to reduce low-value services and the cascades that follow could yield substantial savings.

Preoperative testing before low-risk surgical procedures
TLDR
Despite guideline recommendations to limit testing before low-risk surgical procedures, preoperative ECG and chest radiography were performed frequently, and significant variation across institutions remained after adjustment for patient- and institution-level factors.
Preoperative Laboratory Testing in Patients Undergoing Elective, Low-Risk Ambulatory Surgery
TLDR
Preoperative testing is overused in patients undergoing low-risk, ambulatory surgery, and physician and/or facility preference and not only patient condition currently dictate use.
Patterns of preoperative laboratory testing in patients undergoing outpatient plastic surgery procedures.
TLDR
It is found that there is no association between abnormal laboratory testing and postoperative morbidity, and preoperative testing in low-risk ambulatory plastic surgery patients may be costly and has limited direct clinical benefit.
The value of routine preoperative medical testing before cataract surgery
TLDR
Routine medical testing before cataract surgery does not measurably increase the safety of the surgery and analysis stratified according to age, sex, race, physical status, and medical history revealed no benefit.
Preoperative testing is inconsistent with published guidelines and rarely changes management
TLDR
The majority of elective surgical patients undergo preoperative testing and the results of most tests were normal and influenced management in only 2.6% of cases.
Preoperative medical testing in Medicare patients undergoing cataract surgery.
TLDR
Preoperative testing before cataract surgery occurred frequently and was more strongly associated with provider practice patterns than with patient characteristics.
Elimination of Preoperative Testing in Ambulatory Surgery
TLDR
This pilot study showed that there was no increase in the perioperative adverse events as a result of no preoperative testing in the study population, and a larger study is needed to demonstrate that indicated testing may be safely eliminated in selected patients undergoing ambulatory surgery without increasing peri operative complications.
A population-based study of anesthesia consultation before major noncardiac surgery.
TLDR
Preoperative anesthesia consultation is associated with reduced length of stay but not with reduced mortality, and future research should evaluate the cost-effectiveness of the increasing use of anesthesia consultation.
Routine preoperative medical testing for cataract surgery.
TLDR
It is shown that routine preoperative medical testing does not increase the safety of cataract surgery, and the average cost of performing routine medical testing is estimated to be 2.55 times higher in those with preoperativeMedical testing compared to those without preoperativemedical testing.
