Surgical Care of Patients Experiencing Homelessness: A Scoping Review Using a Phases of Care Conceptual Framework

Ankle fracture surgery in patients experiencing homelessness: a national evaluation of one-year rates of reoperation

Objectives

To evaluate the impact of homelessness on surgical outcomes following ankle fracture surgery.

Design

Retrospective cohort study.

Setting

Mariner claims database.

Patients/Participants

Patients older than 18 years who underwent open reduction and internal fixation (ORIF) of ankle fractures between 2010 and 2021. A total of 345,759 patients were included in the study.

Intervention

Study patients were divided into two cohorts (homeless and nonhomeless) based on whether their patient record contained International Classification of Disease (ICD)-9 or ICD-10 codes for homelessness/inadequate housing.

Main Outcome Measures

One-year rates of reoperation for amputation, irrigation and debridement, repeat ORIF, repair of nonunion/malunion, and implant removal in isolation.

Results

Homeless patients had significantly higher odds of undergoing amputation (adjusted odds ratio [aOR] 1.59, 95% confidence interval [CI] 1.08-2.27, P = 0.014), irrigation and debridement (aOR 1.22, 95% CI 1.08-1.37, P < 0.001), and repeat ORIF (aOR 1.16, 95% CI 1.00-1.35, P = 0.045). Implant removal was less common in homeless patients (aOR 0.65, 95% CI 0.59-0.72, P < 0.001). There was no significant difference between homeless and nonhomeless patients in the rate of nonunion/malunion repair (aOR 0.87, 95% CI 0.63-1.18, P = 0.41).

Conclusions

Homelessness is a significant risk factor for worse surgical outcomes following ankle fracture surgery. The findings of this study warrant future research to identify gaps in surgical fracture care for patients with housing insecurity and underscore the importance of developing interventions to advance health equity for this vulnerable patient population.

Provider perceptions of challenges and facilitators to surgical care in unhoused patients: A qualitative analysis

BACKGROUND

Unhoused patients have worse surgical outcomes than the general population. However, the drivers of this inequity have not been studied.

METHODS

We conducted 26 semi-structured interviews of clinicians who care for patients with surgical disease, using a purposive sampling strategy to intentionally recruit participants with significant experience caring for unhoused patients across different roles. We used thematic analysis to analyze the resulting data.

RESULTS

We conducted 26 interviews: 11 with surgeons (42%), 8 with internal medicine physicians (30%), 2 with surgical advanced practice providers (8%), 3 with social workers or case managers (11%), and 2 with registered nurses (8%). One-third of the participants worked in either medical respite or street medicine programs. We identified 5 themes, each of which was most relevant at a distinct point along the spectrum of surgical care: (1) patients and clinicians face multiple challenges meeting preoperative requirements, (2) although surgeons do not make major operative decisions based on housing status, some take it into consideration for minor care decisions, (3) clinicians perceive that unhoused patients have negative postoperative experiences in the hospital, (4) discharge options for unhoused patients are commonly imperfect, which can lead to inadequate postoperative care, (5) challenges with formal communication between surgeons and non-surgeons are amplified when caring for unhoused patients.

CONCLUSION

Clinicians who care for unhoused patients with surgical disease relayed multiple challenges throughout all phases of surgical care and relied on both formal and informal mechanisms to mitigate these challenges. There may be opportunities to intervene and improve access to surgical care for this vulnerable group.

Access, Outcomes, and Costs Associated with Surgery for Malignancy Among People Experiencing Homelessness

BACKGROUND

Little is known about surgery for malignancy among people experiencing homelessness (PEH). Poor healthcare access may lead to delayed diagnosis and need for unplanned surgery. This study aimed to (1) characterize access to care among PEH, (2) evaluate postoperative outcomes, and (3) assess costs associated with surgery for malignancy among PEH.

METHODS

This was a retrospective cohort study of patients in the Healthcare Cost and Utilization Project (HCUP) who underwent surgery in Florida, New York, or Massachusetts for gastrointestinal or lung cancer from 2016 to 2017. PEH were identified using HCUP's "Homeless" variable and ICD-10 code Z59. Multivariable regression models controlling patient and hospital variables evaluated associations between homelessness and postoperative morbidity, length of stay (LOS), 30-day readmission, and hospitalization costs.

RESULTS

Of 67,034 patients at 566 hospitals, 98 (0.2%) were PEH. Most PEH (44.9%) underwent surgery for colorectal cancer. PEH more frequently underwent unplanned surgery than housed patients (65.3% vs 23.7%, odds ratio (OR) 5.17, 95% confidence interval (CI) 3.00-8.92) and less often were treated at cancer centers (66.0% vs 76.2%, p=0.02). Morbidity rates were similar between groups (20.4% vs 14.5%, p=0.10). However, PEH demonstrated higher odds of facility discharge (OR 5.89, 95% CI 3.50-9.78) and readmission (OR 1.81, 95% CI 1.07-3.05) as well as 67.7% longer adjusted LOS (95% CI 42.0-98.2%). Adjusted costs were 32.7% higher (95% CI 14.5-53.9%) among PEH.

CONCLUSIONS

PEH demonstrated increased odds of unplanned surgery, longer LOS, and increased costs. These results underscore a need for improved access to oncologic care for PEH.

A scoping review of surgical care for people experiencing homelessness: prevalence, access, and disparities

BACKGROUND

Numerous studies have highlighted the inequitable access to medical and psychiatric care that people experiencing homelessness (PEH) face, yet the surgical needs of this population are not well understood. We sought to assess evidence describing surgical care for PEH and to perform a thematic analysis of the results.

METHODS

Ovid MEDLINE, Embase, and Web of Science were searched using the terms "surgery" AND "homelessness." Grey literature was also searched. We used a stepwise scoping review methodology, followed by thematic analysis using an inductive approach.

RESULTS

We included 104 articles in our review. Studies were included from 5 continents; 63% originated in the United States. All surgical specialties were represented with varying surgical conditions and procedures for each. Orthopedic surgery (21%) was the most frequently reported specialty. Themes identified included characteristics of PEH receiving surgical care, homeless-to-housed participants, interaction with the health care system, educational initiatives, barriers and challenges, and interventions and future strategies.

CONCLUSION

We identified significant variation and gaps, representing opportunities for further research and interventions. Further addressing the barriers and challenges that PEH face when accessing surgical care can better address the needs of this population.

Association of Housing Status With Types of Operations and Postoperative Health Care Utilization

OBJECTIVE

To analyze the association between housing status and the nature of surgical care provided, health care utilization, and operational outcomes.

BACKGROUND

Unhoused patients have worse outcomes and higher health care utilization across multiple clinical domains. However, little has been published describing the burden of surgical disease in unhoused patients.

METHODS

We conducted a retrospective cohort study of 111,267 operations from 2013 to 2022 with housing status documented at a single, tertiary care institution. We conducted unadjusted bivariate and multivariate analyses adjusting for sociodemographic and clinical characteristics.

RESULTS

A total of 998 operations (0.8%) were performed for unhoused patients, with a higher proportion of emergent operations than housed patients (56% vs 22%). In unadjusted analysis, unhoused patients had longer length of stay (18.7 vs 8.7 days), higher readmissions (9.5% vs 7.5%), higher in-hospital (2.9% vs 1.8%) and 1-year mortality (10.1% vs 8.2%), more in-hospital reoperations (34.6% vs 15.9%), and higher utilization of social work, physical therapy, and occupational therapy services. After adjusting for age, sex, comorbidities, insurance status, and indication for operation, as well as stratifying by emergent versus elective operation, these differences went away for emergent operations.

CONCLUSIONS

In this retrospective cohort analysis, unhoused patients more commonly underwent emergent operations than their housed counterparts and had more complex hospitalizations on an unadjusted basis that largely disappeared after adjustment for patient and operative characteristics. These findings suggest issues with upstream access to surgical care that, when unaddressed, may predispose this vulnerable population to more complex hospitalizations and worse longer term outcomes.
