Patient satisfaction surveys are widely used to empower patients to voice their concerns and point out areas of deficiency or excellence in the patient‐physician partnership and in the delivery of healthcare services.[1] In 2002, the Centers for Medicare and Medicaid Service (CMS) led an initiative to develop the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey questionnaire.[2] This survey is sent to a randomly selected subset of patients after hospital discharge. The HCAHPS instrument assesses patient ratings of physician communication, nursing communication, pain control, responsiveness, room cleanliness and quietness, discharge process, and overall satisfaction. Over 4500 acute‐care facilities routinely use this survey.[3] HCAHPS scores are publicly reported, and patients can utilize these scores to compare hospitals and make informed choices about where to get care. At an institutional level, scores are used as a tool to identify and improve deficiencies in care delivery. Additionally, HCAHPS survey data results have been analyzed in numerous research studies.[4, 5, 6]

Specialty hospitals are a subset of acute‐care hospitals that provide a narrower set of services than general medical hospitals (GMHs), predominantly in a few specialty areas such as cardiac disease and surgical fields. Many specialty hospitals advertise high rates of patient satisfaction.[7, 8, 9, 10, 11] However, specialty hospitals differ from GMHs in significant ways. Patients at specialty hospitals may be less severely ill[10, 12] and may have more generous insurance coverage.[13] Many specialty hospitals do not have an emergency department (ED), and their outcomes may reflect care of relatively stable patients.[14] A significant number of the specialty hospitals are physician‐owned, which may provide an opportunity for physicians to deliver more patient‐focused healthcare.[14] It is also thought that specialty hospitals can provide high‐quality care by designing their facilities and service structure entirely to meet the needs of a narrow set of medical conditions.

HCAHPS survey results provide an opportunity to compare satisfaction scores among various types of hospitals. We analyzed national HCAHPS data to compare satisfaction scores of specialty hospitals and GMHs and identify factors that may be responsible for this difference.

METHODS

This was a cross‐sectional analysis of national HCAHPS survey data. The methods for administration and reporting of the HCAHPS survey have been described.[15] HCAHPS patient satisfaction data and hospital characteristics, such as location, presence of an ED, and for‐profit status, were obtained from Hospital Compare database. Teaching hospital status was identified using the CMS 2013 Open Payment teaching hospital listing.[16]

For this study, we defined specialty hospitals as acute‐care hospitals that predominantly provide care in a medical or surgical specialty and do not provide care to general medical patients. Based on this definition, specialty hospitals include cardiac hospitals, orthopedic and spine hospitals, oncology hospitals, and hospitals providing multispecialty surgical and procedure‐based services. Children's hospitals, long‐term acute‐care hospitals, and psychiatry hospitals were excluded.

Specialty hospitals were identified using hospital name searches in the HCAHPS database, the American Hospital Association 2013 Annual Survey, the Physician Hospital Association hospitals directory, and through contact with experts. The specialty hospital status of hospitals was further confirmed by checking hospital websites or by directly contacting the hospital.

We analyzed 3‐year HCAHPS patient satisfaction data that included the reporting period from July 2007 to June 2010. HCAHPS data are reported for 12‐month periods at a time. Hospital information, such as address, presence of an ED, and for‐profit status were obtained from the CMS Hospital Compare 2010 dataset. Teaching hospital status was identified using the CMS 2013 Open Payment teaching hospital listing.[16] For the purpose of this study, scores on the HCAHPS survey item definitely recommend the hospital was considered to represent overall satisfaction for the hospital. This is consistent with use of this measure in other sectors in the service industry.[17, 18] Other survey items were considered subdomains of satisfaction. For each hospital, the simple mean of satisfaction scores for overall satisfaction and each of the subdomains for the three 12‐month periods was calculated. Data were summarized using frequencies and meanstandard deviation. The primary dependent variable was overall satisfaction. The main independent variables were specialty hospital status (yes or no), teaching hospital status (yes or no), for‐profit status (yes or no), and the presence of an ED (yes or no). Multiple linear regression analysis was used to adjust for the above‐noted independent variables. A P value<0.05 was considered significant. All analyses were performed on Stata 10.1 IC (StataCorp, College Station, TX).

RESULTS

We identified 188 specialty hospitals and 4638 GMHs within the HCAHPS dataset. Fewer specialty hospitals had emergency care services when compared with GMHs (53.2% for specialty hospitals vs 93.6% for GMHs, P<0.0001), and 47.9% of all specialty hospitals were in states that do not require a Certificate of Need, whereas only 25% of all GMHs were present in these states. For example, Texas, which has 7.2% of all GMHs across the nation, has 24.7% of all specialty hospitals. As compared to GMHs, a majority of specialty hospitals were for profit (14.5% vs 66.9%).

In unadjusted analyses, specialty hospitals had significantly higher patient satisfaction scores compared with GMHs. Overall satisfaction, as measured by the proportion of patients that will definitely recommend that hospital, was 18.8% higher for specialty hospitals than GMHs (86.6% vs 67.8%, P<0.0001). This was also true for subdomains of satisfaction including physician communication, nursing communication, and cleanliness (Table 1).

We next examined the effect of survey response rate. The survey response rate for specialty hospitals was on average 17.4 percentage points higher than that of GMHs (49.6% vs 32.2%, P<0.0001). When adjusted for survey response rate, the difference in overall satisfaction for specialty hospitals was reduced to 8.6% (6.7%10.5%, P<0.0001). Similarly, the differences in score for subdomains of satisfaction were more modest when adjusted for higher survey response rate. In the multiple regression models, specialty hospital status, survey response rate, for‐profit status, and the presence of an ED were independently associated with higher overall satisfaction, whereas teaching hospital status was not associated with overall satisfaction. Addition of for‐profit status and presence of an ED in the regression model did not change our results. Further, the satisfaction subdomain scores for specialty hospitals remained significantly higher than for GMHs in the regression models (Table 1).

DISCUSSION

In this national study, we found that specialty hospitals had significantly higher overall satisfaction scores on the HCAHPS satisfaction survey. Similarly, significantly higher satisfaction was noted across all the satisfaction subdomains. We found that a large proportion of the difference between specialty hospitals and GMHs in overall satisfaction and subdomains of satisfaction could be explained by a higher survey response rate in specialty hospitals. After adjusting for survey response rate, the differences were comparatively modest, although remained statistically significant. Adjustment for additional confounding variables did not change our results.

Studies have shown that specialty hospitals, when compared to GMHs, may treat more patients in their area of specialization, care for fewer sick and Medicaid patients, have greater physician ownership, and are less likely to have ED services.[11, 12, 13, 14] Two small studies comparing specialty hospitals to GMHs suggest that higher satisfaction with specialty hospitals was attributable to the presence of private rooms, quiet environment, accommodation for family members, and accessible, attentive, and well‐trained nursing staff.[10, 11] Although our analysis did not account for various other hospital and patient characteristics, we expect that these factors likely play a significant role in the observed differences in patient satisfaction.

Survey response rate can be an important determinant of the validity of survey results, and a response rate >70% is often considered desirable.[19, 20] However, the mean survey response rate for the HCAHPS survey was only 32.8% for all hospitals during the survey period. In the outpatient setting, a higher survey response rate has been shown to be associated with higher satisfaction rates.[21] In the hospital setting, a randomized study of a HCAHPS survey for 45 hospitals found that patient mix explained the nonresponse bias. However, this study did not examine the roles of severity of illness or insurance status, which may account for the differences in satisfaction seen between specialty hospitals and GMHs.[22] In contrast, we found that in the hospital setting, higher survey response rate was associated with higher patient satisfaction scores.

Our study has some limitations. First, it was not possible to determine from the dataset whether higher response rate is a result of differences in the patient population characteristics between specialty hospitals and GMHs or it represents the association between higher satisfaction and higher response rate noted by other investigators. Although we used various resources to identify all specialty hospitals, we may have missed some or misclassified others due to lack of a standardized definition.[10, 12, 13] However, the total number of specialty hospitals and their distribution across various states in the current study are consistent with previous studies, supporting our belief that few, if any, hospitals were misclassified.[13]

In summary, we found significant difference in satisfaction rates reported on HCAHPS in a national study of patients attending specialty hospitals versus GMHs. However, the observed differences in satisfaction scores were sensitive to differences in survey response rates among hospitals. Teaching hospital status, for‐profit status, and the presence of an ED did not appear to further explain the differences. Additional studies incorporating other hospital and patient characteristics are needed to fully understand factors associated with differences in the observed patient satisfaction between specialty hospitals and GMHs. Additionally, strategies to increase survey HCAHPS response rates should be a priority.
