Brief Summary:
Background
Patient safety has been defined as the avoidance prevention and amelioration of adverse outcomes or injuries stemming from the processes of healthcare1 It has been on the research agenda for more than two decades but more prominently since the report To Err is Human2 To date concern about the safety of patients in hospital settings has driven most research in the field and the knowledge about patient safety in the primary care PC setting is still sparse
More emphasis on research on PC patient safety is needed because many safety incidents identified in hospitals actually originate in PC centres3 which is where the overwhelming majority of healthcare is delivered4 That is especially in Spain country with the highest PC frequentation figures in Europe average of 95 PC consultations per person per year5
The overall aim of this study is to develop and evaluate an intervention targeted at PC professionals to improve patient safety in PC centres by providing them with feedback on patient perceptions experiences and outcomes of patient safety
Specific objectives
1 To translate cross-culturally adapt and validate the Patient Reported Experiences and Outcomes of Safety in Primary Care PREOS-PC instrument into the Spanish context
2 To develop a feasible acceptable low-cost and scalable theory-based intervention targeted at PC professionals to improve patient safety in PC centres by providing them with feedback on patient perceptions experiences and outcomes of patient safety collected through the Spanish version of PREOS-PC
3 To evaluate the acceptability and perceived utility of the intervention and its effectiveness in improving safety climate patient-reported patient safety and reducing avoidable hospitalizations when compared to usual care
Methoddesign
This study will involve 3 stages Stage 1 intervention development will involve a qualitative study with end-users PC providers to explore the acceptability and utility of the proposed intervention and potential implementation barriers b translation cross-cultural adaptation and validation of the PREOS-PC survey for use in the Spanish context c development of the intervention components feedback report and educational materials and d development of an online tool to electronically administrate the PREOS-PC and to automatically generate and send feedback reports to PC centres Stage 2 piloting the intervention will involve a feasibility study in 10 PC centres to inform refinement of the intervention and trial procedures Stage 3 evaluating the intervention will involve a a cluster Randomized Controlled Trial to evaluate the impact of the intervention on patient safety culture patient-reported safety experiences and outcomes and avoidable hospital admissions and b a qualitative study with PC providers to evaluate the acceptability and perceived utility of the intervention

Detailed Description:
METHODS Description of the intervention The intervention will consist in gathering patient-reported experiences and outcomes of the safety of the healthcare patients received in their PC centres during the previous 12 months This information will be processed and fed back to their PC professionals to help them identify potential problems and then target improvements based on problematic areas
The 3 stages of the intervention are
1 Measurement Patients will be approached in the waiting room the study explained and informed consent taken The PREOS-PC questionnaire will be completed using a tablet-computer Patients will be given a choice of whether they would prefer to self-complete the questionnaire or have it facilitated by the researcher
2 Feedback Using a bespoke online tool the information for each PC centre will be collated and presented to the centres in the form of an automatically generated Feedback Report which will offer comparisons with other centres and also include a set of recommendations about how the problems identified could be addressed
3 Action planning and change Participating PC centres will form an Action Planning Team Each team will comprise around four people working in the centres The team will be responsible for receiving the Feedback Report considering which areas should be targeted and developing implementing and monitoring an action plan for safety improvement
This intervention is based on the Feedback Intervention Theory FIT which states that behaviour is regulated through comparison with standards or goals and that feedback can draw attention to existing gaps6 FIT further postulates that once the gap has been identified different methods can be followed in order to decrease it and attain the standard including increasing the effort currently done6 and implementing new strategies to address the problems identified This could result in improving proximal outcomes such as safety climate and potentially impact more distal outcomes eg incidence of safety events or avoidable hospitalizations
Development and evaluation of the intervention The methods described below are based on the Medical Research Council guidance for the development and evaluation of complex interventions7 The development and evaluation of the intervention described above will involve three stages Stage 1 intervention development will involve a a qualitative study with end-users PC providers to explore the acceptability and utility of the proposed intervention and potential implementation barriers b translation cross-cultural adaptation and validation of the PREOS-PC survey for use in the Spanish context c development of the intervention components feedback report and educational materials and d development of an online tool to administrate the PREOS-PC and to automatically generate and send feedback reports to PC centres Stage 2 piloting the intervention will involve a feasibility study in 10 PC centres 260 professionals and 500 patients Stage 3 evaluating the intervention will involve a a cluster randomized controlled trial 48 PC centres 1248 professionals and 3600 patients to evaluate the impact of the intervention on patient safety culture patient-reported safety experiences and outcomes and avoidable hospital admissions and b a qualitative study with PC providers to evaluate the acceptability and perceived utility of the intervention
Stage 1 Intervention development
The development of the proposed intervention involves
1 Qualitative study with PC providers the investigators will conduct three semi-structured interviews and four focus groups with PC doctors nurses and admin staff n36 to examine the acceptability and perceived utility of the proposed intervention and to identify potential barriers towards wider implementation
2 Translation and cross-cultural adaptation of the PREOS-PC instrument8 into the Spanish context The translation process based on state of the art methods9 will consist in forward and back translation by four independent translators followed by cognitive interviews with eight to ten participants diverse in terms of age sex and educational attainment using the think aloud method 10 to ensure the translated version of the questionnaire is easy to understand and complete The cross-cultural adaptation will be carried out using an expert consultation process involving five to seven national experts in PC patient safety
3 Development of the intervention elements the investigators will design the Feedback Report based on findings from previous studies11-15 and from the qualitative study with PC providers above described The Feedback Report will show the results of the Spanish PREOS-PC questionnaire specific for each PC centre It will provide benchmarking data - ie practices will be able to see their individual scores compared to the average scores of the rest of participating practices To facilitate the design of action plans to address the potential safety issues identified in the Feedback Report the investigators will also produce a guidance document including a number of recommendations good practices and materials to improve patient safety in PC which will be identified as a result of a literature review of academic publications and key resources provided by national and international institutions including the World Health Organization16 the European Union Network for Patient Safety and Quality of Care PaSQ Joint Action17 the Agency for healthcare research and quality18 and the LINNEAUS EuroPC Primary Care collaboration19 among others The investigators will also produce a registry form to help PC centres register and monitor progress of the planned actions to address the safety problems identified The intervention materials will also include information to increase PC providers awareness of the usefulness of patient elicited information as a strategy to identify potential safety problems and design strategies to address them
4 Development of an online tool the investigators will develop a bespoke online tool to allow the electronic administration of the PREOS-PC questionnaire to patients using tablet-computers The data collected will be transferred to a database stored in a virtual server Once all data has been collected from all participating patients in each PC centre the tool will automatically generate and send the Feedback Reports to each of the participating centres The tool will also be used to collect data from the healthcare professionals participating in the trial which will be stored in a separate database PC professionals will have password protected authentication to access to the provider questionnaire and to access to the Feedback Report
Stage 2 Piloting the intervention qualitative study and refining the intervention
Piloting the intervention will involve
1 Feasibility study the investigators will pilot the intervention in a three-month one-arm pre-post feasibility trial This will allow us to estimate the follow-up rate for the main trial test the collection of the planned primary and secondary outcome data the willingness of PC centres providers and patients to participate and the trial procedures It will also allow us to examine the psychometric properties floor and ceiling effects internal consistency calculating inter-item correlations20 and Cronbachs α21 and construct validity confirmatory factor analysis of the Spanish PREOS-PC and introduce final changes in the instrument if needed
Participants will include PC centres providers and patients
Sample size assuming an average of 26 healthcare professionals per centre recruiting ten centres will result in approximately 260 professionals taking part in the feasibility trial With 260 healthcare professionals this feasibility study would allow us to detect 80 follow up rate within 95 confidence intervals of 751 to 848 With 500 patients 50 per centre the study is powered to detect a patient response rate to the questionnaire of 75 within 95 confidence intervals of 712 to 788 500 participants are sufficient to perform factor analyses and the rest of analyses planned for the evaluation of the psychometric properties of the Spanish PREOS-PC
Recruitment the investigators will recruit 10 PC centres from the Balearic Islands diverse in terms of list size deprivation and rurality The investigators will recruit patients who will be approached in the waiting room by a research assistant and invited to complete the Spanish PREOS-PC
Statistical analysis The investigators will calculate the overall provider follow-up rate as the proportion of healthcare providers that successfully complete the Spanish Medical Office Survey on Patient Safety Culture MOSPSC22 at baseline and at three months post-intervention The investigators will also calculate the follow-up rate by type of healthcare provider nurse doctor social worker administrative etc Response rate to the patient questionnaire will also be calculated This will include total response rate and response rate by centre and patient characteristics age and gender
2 Embedded qualitative study after the intervention period the investigators will conduct semi-structured qualitative interviews with 20 healthcare professionals They will be purposefully selected to ensure variation in terms of professional roles Thematic analysis 23 will be used to explore the acceptability and perceived utility of the intervention as well as possible suggestions to improve the intervention delivery or content
3 Refining the intervention Results from the feasibility trial will be used to inform the potential refinements of the online tool to collect data and generate the Feedback Reports also about the intervention as well as the trials procedures The investigators will carry out an explicit process to decide the final intervention content including a systematic appraisal of the trial processes both quantitative and qualitative data and proposals for solutions to identified problems
Stage 3 Evaluating the acceptability perceived utility and effectiveness of the intervention
The evaluation of the intervention will involve
1 Cluster randomized controlled trial the investigators will conduct a multi-centre 12 month two-arm two-level cluster randomized controlled trial PC professionals within PC centres with randomization at the centre level in a 11 ratio A cluster randomised trial is proposed to avoid the risk of contamination across professionals working in the same centre 24 PC centres will be allocated to the control group and 24 to the intervention group PC centres in the intervention group will receive the intervention described above Centres in the control group will not receive any intervention during the study period but will receive the Feedback Reports at the end of the study
Randomization Randomization will be done using a fully validated randomisation algorithm Allocation will be carried out using a non-deterministic minimisation algorithm to ensure PC centres are balanced for important characteristics including region deprivation and list size and baseline measures
Participants staff working and patients registered in the included PC centres
Sample size The sample size calculation for this trial is based on its main outcome measure - the Spanish version of the MOSPSC which ranges from 1-5 Assuming an average of 26 professionals per centre approximately 1248 professionals will take part in the study 624 in the intervention and 624 in the control group Assuming a follow-up rate of 80 the investigators will have complete data from approximately 998 professionals Taking into account the cluster design and using a conservative estimation of intra-class correlation of 01 this sample size will allow us to detect at least a 03 difference in effect size with 80 power and a significance level of 5 This would approximately correspond to a difference of 08 points in the index assuming standard deviation of 23 from a previous study 24 The investigators will recruit 75 patients per centre 3600 in total because according to the psychometric study of the original version of PREOS-PC8 that is the number of questionnaires needed to achieve a 07 reliability of scale scores at the centre level A more precise sample size calculation will be possible after the completion of the feasibility trial above described
Recruitment and training of PC centres The investigators will recruit 48 PC centres from Balearic Islands and other regions in Spain Centres will be recruited through scientific societies and key informants Centres will be purposefully selected in order to ensure variation in terms of list size rurality and levels of deprivation Centres will be asked to consent as a unit with all professionals being willing to participate Consent will also be taken from patients invited to complete the patient survey
Data collection Data will be collected at baseline and 12 months post-intervention ie 12 months after the Feedback Reports are sent to the centres The investigators will monitor the progress of the intervention in all the centres Data from patients will include patient reported experiences and outcomes of patient safety in PC measured with PREOS-PC and patient sociodemographic characteristics Data from healthcare professionals will be collected through online questionnaires and will include the perceived safety climate measured with the Spanish MOSPSC and sociodemographic and occupational characteristics Data from centres will include rate of avoidable hospitalizations in the previous 12 months which will be extracted from electronic medical records and centre characteristics rurality list size number of healthcare professionals and deprivation index
Statistical analyses Baseline variables will be presented by randomised group using frequencies with percentages for binary and categorical variables and means and standard deviations or medians interquartile range for continuous variables The results from the trial will be presented as comparative summary statistics difference in proportions or means with 95 confidence intervals The primary outcome will be analysed using a hierarchical model with individuals PC professionals nested within PC centres in an analysis of covariance adjusted for minimisation factors All analyses will be carried out on the basis of intention-to-treat ITT
2 Qualitative study with PC providers within trial qualitative evaluation An embedded qualitative study will be carried out to understand the way the intervention is perceived among PC professionals in terms of acceptability perceived utility and implementation barriers including any unintended consequences Around 30 PC professionals in the intervention centres will be invited to take part in an interview at the end of the trial The investigators will use purposeful sampling in order to ensure variation in terms of type of PC professionals doctors nurses administrative staff etc and of centres region rurality deprivation list size Interviews will take place in the centres or telephonically Thematic analysis23 will be used to identify recurrent themes and subthemes common to interviewees working in centres
The 3 stages of the intervention are
