Marginalized populations are disproportionately affected by HIV, yet they have poor access to health services. Outreach programs focus on improving access, but few are evaluated. We assessed a medical outreach program targeting unstably housed, HIV-infected individuals. We extracted data from 2003–2005 to examine whether keeping medical appointments was associated with patient and program characteristics. Patients kept appointments more frequently when they were walk-in or same-day appointments (compared with future appointments; adjusted odds ratio [AOR]=1.69; 95% confidence interval [CI] = 1.38, 2.08), when they were at a community-based organizations drop-in center (compared with single-room occupancy hotels; AOR=2.50; 95% CI=1.54, 4.17), or when made by nonmedical providers (compared with medical providers; future appointments: AOR = 1.38; 95% CI = 1.05, 1.80; same-day appointments: AOR = 1.70; 95% CI = 1.03, 2.81). These findings demonstrate the importance of program-related characteristics in health services delivery to marginalized populations.
MARGINALIZED POPULATIONS, such as racial/ethnic minorities, substance users, and the unstably housed, are disproportionately affected by HIV disease, yet they have poor access to HIV primary care services.1–8 Many outreach programs focus on improving access to care, but few have been evaluated. Improving access to HIV ambulatory care services is important for public health reasons and is specifically associated with fewer hospitalizations.9 We evaluated a medical outreach program targeting HIV-infected individuals living in single-room occupancy hotels. Specifically, we examined patient- and program-related factors associated with keeping medical appointments.
Since 1999, physicians from Montefiore Medical Center, a university teaching hospital in the Bronx, New York, have collaborated with the outreach team from CitiWide Harm Reduction, a community-based organization in the Bronx that provides harm reduction services to HIV-infected and high-risk individuals.10,11 With the outreach team, physicians deliver medical outreach, including medical triage, evaluation, and education, to single-room occupancy hotel residents. Additional outreach services include harm reduction education and supplies (e.g., condoms, bleach kits to clean syringes), syringe exchange, toilet paper, personal care and first aid kits, and occasionally food. Physicians or other outreach team members also refer residents for services, including medical care to the Health Services Program. Staffed by Montefiore medical providers (physicians, a nurse practitioner, and a physician assistant) and CitiWide nonmedical and supportive service providers (i.e., administrator, administrative assistant, and program assistants and outreach workers), the Health Services Program offers medical services ranging from acute care to comprehensive HIV care. The Health Services Program delivers care in 1 of 3 settings: patients single-room occupancy hotel rooms, CitiWides drop-in center, or Montefiores community clinic. Services provided at the hotel rooms and drop-in center are similar; patient history is obtained and physical examinations, prescriptions, vaccinations, and referrals are provided. Services provided at the clinic are more extensive and also include blood tests and x-rays. Patients interested in utilizing health services can make appointments during outreach or while at CitiWides drop-in center. Appointments are available with any health care provider in all locations. Same-day and walk-in appointments are available at CitiWides drop-in center, and future appointments are available at all locations.
Methods We examined a total of 2666 medical appointment records with unique patient identifiers from CitiWides and Montefiores databases from 2003 to 2005. Data elements included patients sociodemographic information, appointment date, appointment location (i.e., single-room occupancy hotel, CitiWides drop-in center, or Montefiores community clinic), medical provider to be seen, date the appointment was made, person making the appointment (i.e., medical provider or nonmedical provider), and whether the appointment was kept. Appointments made on the same day in which appointments occurred were defined as same-day or walk-in appointments. We used bivariate analyses (using the 2 test) and logistic regression analyses using general estimating equations to evaluate the association between kept appointments and patient- and program-related variables. Records with any missing data elements were dropped (394 or 14.8%). Results were similar when records with partial information were retained.
Patient and Program Characteristics and Kept Appointments
For all appointments, patients kept more same-day and walk-in appointments than they did future appointments (adjusted odds ratio [AOR] = 1.69; 95% confidence interval [CI] = 1.38, 2.08; Table 1
In the Health Services Program, a comprehensive collaborative program providing HIV medical services to a marginalized population, patients kept 29.3% of all appointments. Patients kept appointments more frequently when they were same-day or walk-in appointments compared with future appointments, when they were at CitiWides drop-in center (compared with those at other locations), or when they were made by nonmedical providers (compared with those made by medical providers). There were no differences in kept appointments by patients sociodemographic characteristics, although we collected limited patient-related data. In traditional medical settings, same-day appointments improve access to health care.12,13 This study shows that same-day appointments are important for improving access to care for HIV-infected marginalized individuals as well. Patients were most likely to keep appointments made at CitiWides drop-in center, a place where patients experience "one-stop shopping" by addressing medical and broader structural, social, and psychological needs, than they were at other locations. CitiWides drop-in center provides a full range of services that address needs unique to the target population. Although the clinic has additional on-site resources (e.g., HIV nutritionist, psychiatrist), these resources may not address the populations broader needs. However, the difference in kept appointments between the drop-in center and the clinic was not statistically significant. We were surprised by how few appointments were kept when made by medical providers and when made at the single-room occupancy hotels, particularly because previous research demonstrated medical home visits increased ambulatory visits among disadvantaged individuals.14 Some patients may feel obligated to make appointments if made by medical providers, when they are not truly interested. Furthermore, single-room occupancy hotel residents may want to leave a negative environment, or may not perceive appointments in their rooms as true medical appointments, and therefore do not prioritize them. Based on our findings, we modified the Health Services Program by offering more same-day appointments at CitiWides drop-in center and fewer at the single-room occupancy hotels. Additionally, we are reconsidering the utility of medical providers on outreach. Most studies examining HIV health services utilization focus on patient-related factors. We examined and identified program-related factors that were important in accessing medical services. Although patient-related factors are known to influence health services utilization, the medical community must also focus on system-related factors, such as how health care is delivered, particularly for marginalized populations. Close evaluation of health care delivery is crucial for appropriate resource allocation. Our studys findings that patients kept appointments more frequently when they were walk-in or same-day appointments (compared with future appointments), when they were at a community-based organizations drop-in center (compared with other locations), or when made by nonmedical providers (compared with medical providers), can help guide health care service delivery to marginalized populations.
