Abstract

OBJECTIVE: To evaluate the role of quality indicators and adverse events registering in the quality assessment of intensive care physiotherapy and to evaluate the impact of implementing protocolized care and professional training in the quality improvement process.
METHODS: A prospective before-after study was designed to assess 15 indicators of the quality of care. Baseline compliance and adverse events were collected before and after the implementation of treatment protocols and staff training.
RESULTS: Eighty-nine patients admitted, being 48 in the pre-intervention period and 41 in the post-intervention period with a total of 1246 and 1191 observations respectively. Among the indicators related to the global population, there was a significant improvement in chest x-ray control, multidisciplinary rounds and shift changes as well as in compliance with these decisions. Indicators related to the population under mechanical ventilation, obtained by direct observation at bedside, showed a significant improvement in the compliance with the tidal volume of 6-8mL/Kg, plateau pressure <30cmH2O, adequate mechanical ventilation alarm setting, mechanical ventilation humidification control, adequate humidification line exchange and orotracheal tube position. Among the mechanical ventilation indicators collected through the physiotherapy records, there was significantly improved compliance with the predicted tidal volume registry and cuff pressure registry. There was a significant reduction in the number of adverse events. There was no impact on intensive care unit mortality, length of stay, duration of mechanical ventilation and ventilator-free days.
CONCLUSION: It is possible to measure the quality of physiotherapy care using indicators of quality control. The implementation of care protocols and training of the professionals can improve team performance.

INTRODUCTION

Intensive care units (ICU) are characterized by intense and dynamic routines, requiring prompt decisions that ideally use evidence-based guidelines. The organization of their structure is complex and costly, requiring the excellent management of material and human resources. The quality improvement in intensive care is considered imperative in all of their facets, including security and scientific, ethical, economic and social aspects. The improvement of the care process is one of the most important interventions and involves individual and institutional behavioral changes.(1-5)

The multidisciplinary team in intensive care includes physiotherapists, who are responsible for performing diagnoses and procedures for critically ill patients, such as ventilation, respiratory monitoring and assessments of musculoskeletal, neurological, metabolic and cardiovascular diseases, and for the prevention and treatment of the effects of prolonged immobility. However, there is still large variability in the care, with no standardized quality indicators specific to intensive physiotherapy. The literature on this point is rather sparse, justifying the need for studies on specific indicators for intensive physiotherapy, quality assessment, planning and control services. Therefore, the aims of this study were evaluate the role of quality indicators and adverse events assessment in the quality of intensive care physiotherapy as the evaluate the impact of implementing protocolized care and professional training in the quality improvement process.(6-10)

METHODS

This before-after study was conducted in an ICU of a university hospital. All patients admitted to the ICU aged 18 years or older were consecutively included, regardless of the use of MV. Patients under airborne infection precautions were excluded from the study. The study was approved by the Ethics and Research Committee Universidade Federal de São Paulo under number 1396/08. The Research Ethics Committee waived the need to obtain patient consent due to the characteristics of the study. All physiotherapists involved in the study provided informed consent.

The study was divided into three phases. In the first phase, we established 15 indicators of quality related to physiotherapy based on their relevance to patient care under mechanical ventilation (MV) or not and the ability to perform objective measurements ( Electronic supplementary material - ESM - Table 1). These indicators were applied to three patient settings, which were the whole population, those under MV and those treated with an artificial airway. They were evaluated either by analyzing the patient's chart or the physiotherapy shift change register or by bedside observation. These indicators were assessed one to three times per day, depending on the indicator. Thus, the denominator used to calculate the indicator varied. The baseline data for the compliance with the indicators were collected during one month (October 2008). In this phase, we also established the protocols related to intensive care physiotherapy. The adequacy of the indicators was evaluated based on these protocols. Previously defined adverse events related to physiotherapy care were also collected (ESM - Table 2).

In the second phase of the study (January-March 2009), we implemented the protocols of care and a continuing education program, aiming to train and improve the capacity of the physiotherapy staff. Meetings were held to present the protocols to the professionals on all shifts. All physiotherapy fellows who worked in the unit also participated in this process. All material was revised, sent electronically to the team and made available for open consultation inside the ICU. The team was encouraged to follow the established guidelines, and clinical guidance was discussed in multidisciplinary rounds. All noncompliant situations were discussed with the responsible physiotherapist for guidance. The leadership of the physiotherapy department supported this process, motivating the team to comply with the protocols.

The third phase of the study occurred six months after the implementation of the protocols (September 2009). Compliance with all indicators and the occurrence of adverse events was evaluated and compared with the baseline data. In the first and third phases, we also collected patient characteristics and clinical outcomes, such as ventilator-free days, length of ICU stay and ICU mortality.

Categorical variables were expressed as numbers and percentages, using the chi square test for comparison between groups. Continuous variables were tested using the Shapiro-Wilk test to assess their distribution. Variables without a normal distribution were expressed as medians and interquartile and submitted to the Mann-Whitney test. The results were considered significant with a descriptive value of p<0.05.

RESULTS

We included 89 patients, with 48 in the pre-intervention phase (October 2008) and 41 in the post-intervention phase (September 2009). There were no significant differences in the demographic data, as shown in table 1.

Table 1 - Characteristics of the groups

Among the indicators related to the global population, there was a significant improvement in the chart registry of chest x-ray control, multidisciplinary rounds and clinical decisions in the shift change as well as in the compliance with the decisions of the multidisciplinary round. Among the indicators related to patients under MV that were obtained by direct bedside observation, there was a significant improvement in compliance with a TV of 6-8mL/Kg, plateau pressure <30cmH2O, orotracheal tube position, adequate MV alarm setting, adequate MV humidification control and humidification line exchange. In the same population, for those indicators obtained through the physiotherapy chart records, there were significant improvements in the compliance with the predicted TV registry and cuff pressure registry (Table 2).

DISCUSSION

In this study, we were able to show that it is possible to improve the quality of care offered by intensive physiotherapy by standardizing the processes and developing protocols and actions to improve patient safety. Our results showed a significant increase in 12 of 15 indicators assessed, even in a scenario in which several of them already had high adherence. Among the indicators evaluated, 3 showed no significant change, most likely because they already had compliance above 90% in the initial phase of the study.

We sought to delineate a system applicable in intensive care units using indicators that lend themselves to objective assessment, thereby allowing the system to be reproduced in other services. The professionals had the opportunity to participate in the development of the protocols. Training meetings were held during the working hours inside the units, thus facilitating team participation. Similar studies have shown that the availability of time for professionals to participate in continuing education programs is a barrier to be overcome, as gathering a team at a single time can be a complex task.(9,11,12)

This sort of continuing education proved to be a viable alternative to ensure the team's participation in these programs. Additionally, the participation of the ICU physiotherapy leadership in this process was important to validate the actions taken by strengthening communication and teamwork.(1,9,13-15)

The challenge in this type of study is related to changing the team's behavior and instituting new clinical practices, which requires the professionals to be aware of the relevance of these modifications and the need for sustained actions to maintain the achieved results. It is important to emphasize that this quality assessment has been specially designed for intensive physiotherapy, using careful methodology and systematic collection with more than one daily observation to increase accuracy. The use of indicators and protocols in accordance with clinical guidelines recommended in the literature possibly facilitated the achievement of good compliance by the healthcare team. The forms created were well accepted by the team and were incorporated into the routine, even after the end of the study.

The assessment of adverse events was an important strategy for improving the professionals' perceptions of the critical status of our patients. We observed a significant reduction in the occurrence of events after the proposed interventions. Similar studies have also noted the importance of developing a culture of safety among ICU team professionals, with numerous strategies being developed to identify risk situations and prevent complications during hospitalization.(4,5,10,16-18)

Despite adequate results in the quality indicators, there was no significant impact on the clinical outcomes. Although it was possible to improve the physiotherapy care, an impact on global clinical outcomes is less likely to occur considering the importance of the multidisciplinary treatment of patients. The indicators assessed in this study concerned only the assistance of intensive physiotherapy and were not designed to assess the impact of actions taken by other teams working in the ICU, which could also influence these outcomes. Moreover, many of the indicators already had high compliance at baseline, and even a significant improvement would likely not impact the clinical outcomes. However, demonstrating this impact would be easier in services with lower compliance rates.

Our study has some limitations. We highlight the scarcity of similar studies in the literature, making it difficult to compare results. The diversity of the role of the physiotherapist in intensive care is also a limiting factor, as each service can set different tasks for this professional. As this was a single centre study, the reproducibility of these indicators can be limited because we could not assess them in other contexts, such as ICU indicators with low baseline compliance. This factor reduces the external validity of our results. As the team knew about the quality implementation process, we were unable to collect data in a blinded fashion, which could have influenced the baseline compliance and even the post-intervention data. The lack of long-term follow-up also precludes the evaluation of whether the results were sustained. Further studies could be designed with a longer observation time and a larger number of patients.

CONCLUSION

In summary, our results showed that it is possible to measure the quality of physiotherapy care through quality indicators and the occurrence of adverse events. Moreover, implementing care protocols and professional training is able to improve the team's performance in terms of the indicators selected.
