Patient Safety and Quality Improvement in Otolaryngology-Head and Neck Surgery: A Systematic Review

The current landscape of patient safety/quality improvement (PS/QI) research dedicated to Otolaryngology-Head and Neck Surgery (OHNS) has not been established. This systematic review aims to define the breadth and depth of PS/QI research dedicated to OHNS and to identify knowledge gaps as well as potential areas of future study.

The study protocol was developed a priori using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) process. A computerized Ovid/Medline database search was conducted (January 1, 1965-September 30, 2019). Similar computerized searches were conducted using Cochrane Database, PubMed, and Google Scholar. Articles were classified by year, subspecialty, PS/QI category, Institute of Medicine (IOM) Crossing the Chasm categories, and World Health Organization (WHO) subclass.

Computerized searches yielded 11,570 eligible articles, 738 (6.4%) of which met otolaryngology PS/QI inclusion criteria; 178 (24.1%) were not specific to any one subspecialty. The most prevalent subspecialty foci were head and neck (29.9%), pediatric otolaryngology (16.9%), and otology/neurotology (11.0%). Studies examining complications or risk factors (32.0%) and outcomes/quality measures (16.3%) were the most common foci. Classification by the IOM included effective care (31.4%), safety (29.9%), and safety/effective care (25.3%). Most research fell into the WHO categories of understanding causes (28.5%) or measuring harm (28.3%).

Most OHNS PS/QI projects (32.0%) focus on reporting complications or risk factors, followed by outcomes/quality measures (16.3%). Knowledges gaps for future research include healthcare disparities, multidisciplinary care, and the WHO category of studies translating evidence into safer care.
