Objective:
Measuring disability as a concept of impaired global function enables beneficiaries of treatment, the impact of treatment, and targets of health system investment to be rigorously assessed. Measures of disability are not well established for cleft lip and palate. This study aims to systematically review disability weight (DW) studies pertaining to orofacial clefts (OFCs) and identify methodological strengths and shortcomings of each approach.
Design:
Systematic literature review of studies that met the following criteria: (1) peer-reviewed publication, (2) focus on disability valuation, (3) mention orofacial clefts, and (4) publication January 2001-December 2021.
Setting:
None.
Patients/Participants:
None.
Interventions:
None.
Main Outcome Measure(S):
Disability weight method of valuation and the value itself.
Results:
The final search strategy yielded 1,067 studies. Seven manuscripts were ultimately included for data extraction. The disability weights used in our studies, including those newly generated or taken from the Global Burden of Disease Studies (GBD), ranged widely for isolated cleft lip (0.0-0.100) and cleft palate with or without cleft lip (0.0-0.269). The GBD studies limited their consideration of cleft sequelae informing disability weights to impact on appearance and speech-related concerns, while other studies accounted for comorbidities such as pain and social stigma.
Conclusions:
Current measures of cleft disability are sparse, inadequately reflect the comprehensive impact of an OFC on function and socialization, and are limited in detail or supporting evidence. Use of a comprehensive health state description in evaluating disability weights offers a realistic means of accurately representing the diverse sequelae of an OFC.
