Abstract

The Pittsburgh Sleep Quality Index (PSQI) is a valid patient-reported outcome measure developed to assess sleep quality and disturbances in clinical populations. This study aimed to calculate the minimum clinically important difference (MCID) and the patient acceptable symptom state (PASS) for the PSQI in patients who underwent rotator cuff repair (RCR). Preoperative and six-month postoperative follow-up questionnaires were completed by 50 patients (25 males and 25 females, mean age 58.7 ± 11.1 years). The MCID of the PSQI was calculated using distribution-based and anchor methods. To calculate the PSQI’s PASS, the 75th percentile approach and the receiver operating characteristic (ROC) curve were used. The MCID from preoperative to 6 months postoperative follow-up is 4.4. Patients who improved their PSQI score of 4.4 from baseline to 6 months follow-up had a clinically significant increase in their health status. The PASS is 5.5 for PSQI; therefore, a value of PSQI at least 5.5 at six months follow-up indicates that the symptom state can be considered acceptable by most patients.

Highlights

Rotator cuff tear (RCT) is the cause of 70% of all outpatient visits for shoulder pain [1].The incidence of RCT in patients aged 60–80 years ranged from 20% to 54% [2]
In RCT patients, sleep disturbances represent one of the leading causes that address the patient to the surgery
This study aimed to estimate the value of Pittsburgh Sleep Quality Index (PSQI) in patients who received rotator cuff repair (RCR) and perceive the procedure as successful

Summary

Introduction

Rotator cuff tear (RCT) is the cause of 70% of all outpatient visits for shoulder pain [1]. The incidence of RCT in patients aged 60–80 years ranged from 20% to 54% [2]. Patients aged under 60 years show an incidence of 6% [3]. In RCT patients, sleep disturbances represent one of the leading causes that address the patient to the surgery. More than 87% of patients with RCT suffer from sleep disturbance in the preoperative period [6]. The burden of this condition is relevant, as sleeping influences biological functions [7,8], learning, memory, and quality of life [9]
