Cross-Cultural Adaptation, Validation, and Piloting of the Patient Reported Experiences and Outcomes of Safety in Primary Care Questionnaire for Its Use in Spain

Evaluation of the psychometric performance of the Spanish and Catalan versions of the patient reported experiences and Outcomes of Safety in Primary Care (PREOS-PC)-Compact questionnaire

BACKGROUND

Patients provide a unique, irreplaceable, and essential perspective in evaluating patient safety. The suite of Patient Reported Experiences and Outcomes of Safety in Primary Care (PREOS-PC) tools are a notable exception to the scarcity of patient-reported patient safety measures. Full evaluation of their performance has only been attempted for the English version, thereby limiting its international applicability.

OBJECTIVES

To assess the psychometric performance of the Spanish and Catalan versions of the PREOS-PC-Compact.

METHODS

Cross-sectional validation study. We used Classical Test Theory methods to examine scale score distribution, internal consistency, and construct validity; and Item Response Theory (IRT) methods to further explore construct validity.

RESULTS

3287 patients completed the Spanish version, and 1007 the Catalan version. Similar results were obtained for both versions. Confirmatory Factor Analysis supported a single construct for each scale. The correlations between PREOS-PC-Compact scales and known group analysis suggested adequate construct validity (inconclusive for known groups at the provider level). All four multi-item scales demonstrated adequate internal consistency reliability (α > 0.7), which was only confirmed for test-retest reliability for 'Practice activation.' A sample between 60-90 patients per practice was estimated sufficient to produce scores with reliability > 0.7 for all scales except for harm scales. IRT models showed disordered thresholds for 'Practice activation' and 'Harm burden' but showed excellent fit after reducing the response categories.

CONCLUSION

The Spanish and Catalan versions of the PREOS-PC-Compact are broadly valid and reliable tools to measure patient safety in Spanish primary care centres; confirmation of lower-than-expected test-rest reliability merits further examination .

Feasibility of the SINERGIAPS ("Sinergias entre profesionales y pacientes para una Atención Primaria Segura") intervention for improving patient safety in primary care

AIM

The primary aim was to examine the feasibility of intervention delivery and of trial procedures. Secondary aims were to study the intervention uptake; its acceptability and perceived utility; and its potential to improve safety culture and avoidable hospital admissions.

METHODS

We conducted a 3-month, single-arm feasibility study in 10 primary care (PC) centres in Spain. Centres received information regarding patients' experiences of safety (through the Patient Reported Experiences and Outcomes of Safety in Primary Care [PREOS-PC] questionnaire), and were instructed to plan safety improvements based on that feedback. We used a bespoke online tool to recruit PC professionals, collect patient feedback, and deliver it to the centres, and to collect outcome data (patient safety culture [Medical Office Survey on Patient Safety Culture, MOSPSC questionnaire]). We measured recruitment and follow-up rates and intervention uptake (based on the number of safety improvement plans registered). We conducted semistructured interviews with 9 professionals to explore the intervention acceptability and perceived utility.

RESULTS

Of 256 professionals invited, 120 (47%) agreed to participate, and 97 completed baseline and postintervention measures. Of 780 patients invited, 585 (75%) completed the PREOS-PC questionnaire. Five of 10 centres (50%) designed an improvement plan, providing 27 plans in total (range per centre, 1-14). The intervention was perceived as a novel strategy for improving safety, although the healthcare professionals identified several factors limiting its acceptability and utility: lack of feedback at the individual professional level; potentially unrepresentative sample of patients providing feedback; and number of educational materials deemed overwhelming.

DISCUSSION

It is feasible to deliver the proposed intervention so long as the identified limitations are addressed.

Assessing the Impact of Multi-Morbidity and Related Constructs on Patient Reported Safety in Primary Care: Generalized Structural Equation Modelling of Observational Data

We aimed to examine the complex relationships between patient safety processes and outcomes and multimorbidity using a comprehensive set of constructs: multimorbidity, polypharmacy, discordant comorbidity (diseases not sharing either pathogenesis nor management), morbidity burden and patient complexity. We used cross-sectional data from 4782 patients in 69 primary care centres in Spain. We constructed generalized structural equation models to examine the associations between multimorbidity constructs and patient-reported patient safety (PREOS-PC questionnaire). These associations were modelled through direct and indirect (mediated by increased interactions with healthcare) pathways. For women, a consistent association between higher levels of the multimorbidity constructs and lower levels of patient safety was observed via either pathway. The findings for men replicated these observations for polypharmacy, morbidity burden and patient complexity via indirect pathways. However, direct pathways showed unexpected associations between higher levels of multimorbidity and better safety. The consistent association between multimorbidity constructs and worse patient safety among women makes it advisable to target this group for the development of interventions, with particular attention to the role of comorbidity discordance. Further research, particularly qualitative research, is needed for clarifying the complex associations among men.
