Abstract Purpose To quantitatively assess the use of patient-reported outcome measures in studies involving patients undergoing inguinal hernia repair. Methods We performed a systematic literature search in Medline and EMBASE. We included all studies published between 2000 and 2019 that involved > 5 patients receiving inguinal hernia repair and evaluated a postoperative patient-reported outcome measure. Studies were stratified in 5-year intervals. We extracted data on which patient-reported outcome measure was used, its time of administration, study design, and the size and composition of the study population. Data were presented using descriptive statistics. Results We included 929 studies that covered 81 different patient-reported outcome measures. Of these, the Short-Form 36 was the most commonly used generic instrument (14%), the Carolinas Comfort Scale was the most commonly used herniaspecific instrument (5%), and the Visual Analogue Scale was the most commonly used domain-specific instrument (70%). There was a proportional decrease in the use of generic instruments, from 24% of studies in 2000–2004 to only 14% of studies in 2015–2019. Conversely, there was an increase in the use of hernia-specific instruments, from 0% in 2000–2004 to 18% in 2015–2019. Conclusions There is heterogeneity in the use of patient-reported outcome measures in the field of inguinal hernia research. The use of hernia-specific instruments is increasing, the use of generic instruments is decreasing, and the use of domainspecific instruments remains consistently high. This study serves as a repository of all available patient-reported outcome measures relevant to patients undergoing inguinal hernia repair.

Introduction Inguinal hernia repair is one of the most frequently performed surgical interventions in the world with estimated 20 million procedures annually [1]. This is a reflection of the high lifetime risk of developing an inguinal hernia, which is approximately 27% for men and 3% for women [1].
