Brief Summary

The study is a retrospective cohort study of adult patients undergoing outpatient primary unilateral total knee or total hip replacement surgeries from 2017 to 2019 assessing for difference in anesthetic techniques and outcomes.

Detailed Description

The study is a retrospective cohort study of adult patients undergoing outpatient primary unilateral total knee or total hip replacement surgeries from 2017 to 2019. The purpose of the study is to evaluate the effects of anesthetic techniques for primary total joint replacement in Northern California Kaiser Permanente. The primary objective is to determine if there are clinically and statistically significant differences between the outcomes of general anesthesia and neuraxial anesthesia.

Primary Outcome Measures
NameTimeMethod
Postoperative Morbidity30-day postoperative

30-day Postoperative Morbidity including surgical site infection (defined as infection involving the skin or subcutaneous tissue of the incision, deep incisional infection defined as infected tissue below the subcutaneous tissue including fascia and muscle), major coronary events (defined as nonfatal myocardial infarction, heart failure, ventricular tachycardia, cardiac arrest), pneumonia, urinary tract infection, venous thromboembolism, pulmonary embolism, cerebrovascular accident, renal injury/failure (Defined as increase in baseline creatinine 2 fold/3fold respectively).

Secondary Outcome Measures
NameTimeMethod
Postoperative readmission30-day postoperative

30-day postoperative readmission - all cause

Postoperative opioid useDay of surgery

Defined by type of analgesic medication and total morphine equivalence

Postoperative Mortality30-day postoperative

30-day postoperative mortality - all cause

Intraoperative blood loss and transfusion ratesDay of surgery

Measurement of blood loss by mL recorded on record. Measurement of packed red blood cells transfused by unit pack.

Length of postsurgical hospital stayDay of surgery

Length of time defined from end of intraoperative time to discharge from hospital time

Intraoperative opioid useDay of surgery

Defined by type of analgesic medication and total morphine equivalence

Postoperative Pain ScoresDay of surgery

Numerical Rating Scale of postsurgical pain measured until discharge from hospital. Numerical rating scale for pain is described as a scale from a minimum of 0, associated with no pain, to a maximum of 10, associated with the worst possible pain. A higher number is associated with a worse outcome.

Postoperative nausea and vomitingDay of surgery

Rate of PONV after surgery
