Insights
The Nursing Home Survey on Patient Safety Culture can be adapted to measure patient safety culture in pediatric long-term care facilities. This validated tool helps identify areas for improvement in these specialized settings.
Area of Science:
- Healthcare Management
- Patient Safety
- Pediatric Care
Background:
- The number of children with complex medical needs is rising, increasing demand for pediatric long-term care (pLTC) facilities.
- A strong patient safety culture (PSC) is crucial in pLTC, but no validated measurement tool exists for this unique setting.
- Existing tools need evaluation for suitability in the hybrid acute care-residential environment of pLTC.
Purpose of the Study:
- To evaluate the psychometric properties of the Nursing Home Survey on Patient Safety Culture (NHSOPSC) adapted for pLTC.
- To determine if the NHSOPSC, with minor modifications, is a reliable instrument for assessing PSC in pediatric long-term care.
Main Methods:
- Factor analyses (principal axis factoring, confirmatory, and exploratory) were conducted on data from 239 staff across 3 pLTC facilities.
- Reliability was assessed using Cronbach's alpha.
- The original 12-dimension structure was tested and compared to a modified structure.
Main Results:
- Exploratory factor analysis suggested 4 dimensions (staffing, nonpunitive response to mistakes, communication openness, organizational learning) might not fit well.
- Both original and modified NHSOPSC factor solutions showed similar reliabilities to those reported for adult nursing homes.
- Items factored nearly identically as theorized in the pLTC setting.
Conclusions:
- The NHSOPSC, with minimal modifications, appears appropriate for measuring PSC in pLTC settings.
- Further psychometric testing is recommended to validate its use and examine relationships with safety outcomes.
- Wider use can provide benchmarking data to guide improvements in pediatric long-term care safety.
Objectives:
Children with complex medical needs are increasing in number and demanding the services of pediatric long-term care facilities (pLTC), which require a focus on patient safety culture (PSC). However, no tool to measure PSC has been tested in this unique hybrid acute care-residential setting. The objective of this study was to evaluate the psychometric properties of the Nursing Home Survey on Patient Safety Culture tool slightly modified for use in the pLTC setting.
Methods:
Factor analyses were performed on data collected from 239 staff at 3 pLTC in 2012. Items were screened by principal axis factoring, and the original structure was tested using confirmatory factor analysis. Exploratory factor analysis was conducted to identify the best model fit for the pLTC data, and factor reliability was assessed by Cronbach alpha.
Results:
The extracted, rotated factor solution suggested items in 4 (staffing, nonpunitive response to mistakes, communication openness, and organizational learning) of the original 12 dimensions may not be a good fit for this population. Nevertheless, in the pLTC setting, both the original and the modified factor solutions demonstrated similar reliabilities to the published consistencies of the survey when tested in adult nursing homes and the items factored nearly identically as theorized.
Conclusions:
This study demonstrates that the Nursing Home Survey on Patient Safety Culture with minimal modification may be an appropriate instrument to measure PSC in pLTC settings. Additional psychometric testing is recommended to further validate the use of this instrument in this setting, including examining the relationship to safety outcomes. Increased use will yield data for benchmarking purposes across these specialized settings to inform frontline workers and organizational leaders of areas of strength and opportunity for improvement.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
