What You'll Learn
Patient characteristics
The NHDS, conducted annually from 1970 to 2010, focused on gathering information from non-federal short-stay hospitals in the United States. It collected data on patient characteristics such as age, sex, race, ethnicity, marital status, and expected sources of payment. Additionally, the NHDS captured administrative details like admission and discharge dates, length of stay, and discharge status. This comprehensive approach allowed researchers to understand the diverse nature of the patient population and their interactions with the healthcare system.
The HCAHPS survey, on the other hand, is a nationally standardized survey designed to assess patients' perspectives on hospital care. It includes questions about critical aspects of the patient experience, such as communication with medical staff, the responsiveness of hospital personnel, the cleanliness and quietness of the environment, medication discussions, and discharge information. By understanding patients' perceptions, the HCAHPS survey provides a tool for hospitals to enhance the quality of care and improve accountability.
In addition to the NHDS and HCAHPS, other surveys, such as the Nationwide Inpatient Sample (NIS), contribute valuable patient characteristic data. The NIS, with its larger sample size, captures detailed information on patient demographics, comorbidities, adverse events, and length of hospital stay. By comparing databases like the NHDS and NIS, researchers can gain deeper insights into patient characteristics and identify variations in discharge status, length of stay, and in-hospital mortality rates.
These surveys play a crucial role in healthcare research and quality improvement initiatives. They provide a wealth of information on patient characteristics, allowing healthcare providers, researchers, and policymakers to make informed decisions, develop targeted interventions, and ultimately improve patient care and outcomes.

Quality of care
Hospital discharge surveys are an important tool for assessing the quality of care provided to patients. By collecting feedback from patients who have been discharged from the hospital, healthcare providers can gain valuable insights into the patient experience and identify areas for improvement.
One example of a hospital discharge survey is the HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) survey, which is a nationally standardized survey designed to measure patients' perceptions of their hospital experience. The HCAHPS survey asks discharged patients a range of questions about their recent hospital stay, including communication with doctors and nurses, the responsiveness of hospital staff, the cleanliness and quietness of the hospital environment, communication about medications, discharge information, and their overall rating of the hospital.
The survey is administered to a random sample of adult patients across different medical conditions between 48 hours and six weeks after discharge. Hospitals have the flexibility to choose from four different survey modes: mail, telephone, mail with telephone follow-up, or active interactive voice recognition (IVR). Additionally, the survey is available in multiple languages to ensure accessibility for a diverse range of patients.
The HCAHPS survey serves multiple purposes. Firstly, it provides valuable data that allows objective and meaningful comparisons between hospitals on topics that are important to consumers. Secondly, public reporting of the survey results creates incentives for hospitals to improve the quality of care they provide. Hospitals are encouraged to enhance accountability and transparency by publicly sharing the quality of care they offer in return for public investment.
Overall, hospital discharge surveys, such as HCAHPS, play a crucial role in driving improvements in healthcare quality. By collecting and analyzing patient feedback, hospitals can identify areas of strength and weakness, make informed decisions, and implement changes that positively impact patient experiences and outcomes. This continuous quality improvement process helps to ensure that patients receive the best possible care during their hospital stay and beyond.

Inpatient records
The NHDS utilized two data collection procedures: a manual system and an automated system. In the manual system, hospital staff or U.S. Census Bureau staff selected samples and transcribed medical information from hospital records to abstract forms. The automated system, on the other hand, involved purchasing electronic data files from commercial organizations, state data systems, or hospitals. These forms and data tapes included personal characteristics such as age, sex, race, ethnicity, marital status, and payment sources. Additionally, administrative details like admission and discharge dates, length of stay, and discharge status were recorded.
The NHDS data is valuable for various purposes. It is used by governmental, scientific, academic, and commercial institutions for research and analysis. The data provides insights into inpatient demographics, payment sources, length of stay, and discharge status. This information can be crucial for understanding healthcare utilization, outcomes, and trends.
Another important survey, the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), focuses on patients' perspectives on hospital care. It is the first national, standardized, and publicly reported survey of its kind. The HCAHPS survey asks discharged patients 29 questions, with 19 core questions covering critical aspects such as communication with staff, responsiveness, cleanliness, discharge information, and overall hospital rating. This survey is administered randomly to adult patients within 48 hours to six weeks after discharge, and it is available in multiple languages.
The HCAHPS survey serves multiple purposes. Firstly, it incentivizes hospitals to improve the quality of care by publicly reporting the results. Secondly, it enhances accountability and transparency in healthcare. Additionally, the survey data is used to calculate value-based incentive payments in the Hospital Value-Based Purchasing program. Together, these surveys provide comprehensive insights into inpatient records and experiences, contributing to the overall improvement of healthcare services.

Consider the characteristics of the patient population served by the hospital. Hospitals in urban and rural areas may have different patient demographics, including age, gender, ethnicity, and socioeconomic status. Selecting hospitals that serve diverse patient populations can provide a more comprehensive understanding of patient experiences and perspectives.
Data Collection Procedures
The data collection procedures employed by the hospital should align with the survey's methodology. Some hospitals may have well-established data collection systems, such as electronic medical records or established patient satisfaction surveys, that can facilitate the survey process. Consider the compatibility of the hospital's data collection methods with the survey requirements to ensure efficient and accurate data gathering.
Hospital Willingness and Capacity
Ensure that the selected hospitals are willing and able to participate in the survey. This includes assessing their capacity to dedicate the necessary time and resources to data collection and survey administration. Hospitals with established research partnerships or those that routinely collect and report patient experience data may be more receptive to participation.
