Increased Utilization of Ambulatory Occupational Therapy and Physical Therapy After Medicaid Expansion

Greater Socioeconomic Deprivation Is Associated With Increased Complication Rates and Lower Patient-Reported Outcomes Following Open Reduction and Internal Fixation of Humeral Shaft Fractures

OBJECTIVES

This study explored the hypothesis that social determinants of health, including racial and economic differences, may impact orthopaedic trauma outcomes in patients undergoing open reduction and internal fixation of humeral shaft fractures.

METHODS

DESIGN

Retrospective.

SETTING

Single, academic, tertiary level I trauma center.

PATIENT SELECTION CRITERIA

Adults with midshaft humerus fractures (Orthopaedic Trauma Association/Association of Osteosynthesis 12) were treated operatively with plate fixation from May 2011 to May 2021 with a minimum follow-up of 9 months.

OUTCOME MEASURES AND COMPARISONS

Radiographic fracture healing, complication rates, and patient-reported outcomes were investigated. Social determinants of health were assessed using the Area Deprivation Index (ADI). Demographics, complication rates, and patient-reported clinical outcomes were compared between the first and fourth ADI quartiles.

RESULTS

One hundred ninety-six patients fit the study criteria. The average age of the cohort was 47 years with 100 women (51%). Comparisons of the least deprived quartile (n = 49) with the most deprived quartile (n = 49) yielded similar sex distribution (59% vs. 43% females, P = 0.15), fewer non-White patients (8% vs. 51%, P < 0.01), older average age (51 vs. 43 years, P = 0.05), similar body mass index (30.5 vs. 31.8, P = 0.45), and higher Charlson Comorbidity Index (2.2 vs. 1.1, P = 0.03). While nonunion rates were similar ( P = 0.20) between groups, the most deprived quartile had 2.3 times greater odds of postoperative complications ( P = 0.04). Patients in the most deprived group exhibited higher Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference scores ( P < 0.01) and PROMIS Depression (D) scores ( P = 0.01), with lower PROMIS Physical Function scores ( P < 0.01) at 6-month follow-up than the least deprived cohort. The most deprived cohort had 3 times higher odds of missing scheduled appointments within the first postoperative year ( P < 0.01), resulting in a significantly higher no-show rate ( P < 0.01) than the least deprived cohort. Regression analysis including several demographic and injury factors identified that ADI was significantly associated with the occurrence of any missed appointments ( P < 0.01), no-show rates ( P = 0.04), and experiencing one of the following postoperative complications during recovery: nonunion, radial nerve injury, or dysfunction ( P = 0.03).

CONCLUSIONS

Patients experiencing greater resource deprivation faced increased odds of complications, missed appointments, and poorer PROMIS outcomes following humeral shaft fracture fixation. These findings suggest that baseline socioeconomic disparities predict unfavorable postoperative outcomes even given favorable baseline health status according to the Charlson Comorbidity Index score.

Social determinants of health are associated with physical therapy use: a systematic review

OBJECTIVE

The purpose of this systematic review is to identify and summarise the social determinants of health (SDH) cited in the literature and evaluate their association with individuals using physical therapy services.

DESIGN

A systematic review using qualitatively synthesised information to describe the association between SDH and physical therapy use.

DATA SOURCES

The electronic databases Medline, Embase and Scopus were searched from inception to February 2021, identifying observational and qualitative studies.

ELIGIBILITY CRITERIA

Published studies included all adults, aged 18 or older, who independently sought to use physical therapy, in all practice settings from all geographical locations.

RESULTS

Of the 9248 studies screened, 36 met the inclusion criteria for the review. The participants represented 8 countries and totaled 2 699 437. The majority of the papers reported moderate strength of association for each SDH. Female gender, non-Hispanic white race/ethnicity, increased education attainment, urban environment, access to transportation, employment, high socioeconomic status and private insurance were associated with higher likelihood of physical therapy use.

CONCLUSION

This systematic review identifies predisposing and enabling factors impacting physical therapy usage among adults in different countries and across physical therapy settings. The results of this study have implications for policy and future research regarding populations that have been shown to be using physical therapy services less, such as those with lower levels of education, those in a rural area, or those in a low socioeconomic class.
