A pilot study on assessing the gap between nurses’ task performances and knowledge pertaining the same with reference to “ I COUGH” initiative- a call for promoting patient ‘care bundle’ assignments in low-income nations

Introduction

Among surgical specialties worldwide, there is alarmingly high incidence of post-operative pulmonary complications, being reported as high as 40%, and leading to 30 days post-surgery mortality for almost 20%¹. These complications also lead to an increase in average hospital stay by 8 days and thereby increase in average hospital costs by almost 55%¹ Therefore, there is a substantial need to produce a care bundle based on an enhanced recovery protocol within these surgical specialties¹.

In context of low-income nations like Nepal, with a per capita income of below US $700, the current health sector situation is even more alarming. The limited resources available coupled with political turmoil further exacerbates the issue². It reportedly has only 16.7 intensive care unit (ICU) beds per million of its population³. Even in the capital city, only 7.2 ICU beds equipped to provide backup ventilation are available per 100,000 of the population. Moreover, there is a significant shortage of effective manpower, with a nurse patient ratio of >1:4 during night shifts⁴. The present nurse to population ratio in Nepal is approximately 11 nurses per 10,000 of the population (with 50 considered to be optimum)⁵. Recruitment of nurses is low in national hospitals with many opting to go abroad owing to higher salaries, improved facilities and relatively better scope for career building opportunity. This accounts for the temporary employment pattern prevalent in our hospitals; with one study showing up to 50 nurses leaving their hospital within a single calendar year. Moreover, lack of in-service education and timely reforms of the existing nursing guidelines have further affected the nursing profession⁵.

The I COUGH program is a postoperative pulmonary care bundle approach aimed at reducing the incidence of postoperative pneumonia and unplanned intubation among patients⁶. This acronym incorporates six variables namely 1) Incentive spirometry, 2) Cough/ chest physiotherapy, 3) Oral care, 4) Understanding, 5) Get out of bed and 6) Head end elevation⁶.

Such initiative not only helped promote patient’s health but also in improving performance standards and thereby their autonomy¹. Therefore, currently upmost emphasis is being given for promoting such performance appraisal methods¹. There is upmost need for bridging the gap between nurses’ performance and knowledge of the underlying reasons for the tasks they perform through the application of care bundle approaches such as the I COUGH initiative⁶.

We performed a pilot study to identify significant discrepancy between the knowledge of and performance of relevant tasks among health care providers in the critical care setting up in regards to the I COUGH initiative, and thereby call for initiation of care bundle approaches in our context as well.

Methods

Results

A total of 101 nurses working in the intensive care and high dependency neurosurgical units were enrolled for our study within three different teaching hospitals under Kathmandu University. The average scores obtained by the nurses from three hospitals were below 50% scores (37.83%, 40.83% and 42.33% respectively) in terms of their knowledge while comparing to the I COUGH strategy items (Figure 1). The average scores of the nurses were 2.27, 2.45 and 2.54 for CMS, NINAS and NMCTH respectively.

In terms of individual variables of I COUGH, Cough and Head end elevations were mentioned by most number of nurses whereas Oral hygiene and Understanding aspects were mentioned by the least number of nurses (Figure 2).

Cough was mentioned the most (96.42%, 97% and 100% respectively) whereas oral hygiene was mentioned the least (Figure 3 and Figure 4).

In terms of individual variables, Incentive spirometry was mentioned by most nurses from College of Medical Sciences whereas Cough was mentioned the highest from nurses of Nobel Medical College and National institute of Neurosurgery and Allied Sciences institutions (Figure 5).

Despite naming Cough correctly by most nurses from all three institutions, paradoxically none of the nurses correctly mentioned of all the essential components of Chest physiotherapy.

Discussion

VAP in associated in 9–27% of all mechanically ventilated patients⁷. One study showed incidence of 25 VAPs per 100 ventilated patients, thereby protracting ICU stays and increasing the risk of mortality among them⁸. The provision of dedicated physiotherapists in critical care is still in its infancy in our context⁹.

Nurses play pivotal role by standing in the frontline of the health surveillance systems and thereby are supposed to detect, make inferences and then implement the correct course of action during any adverse events in the ICU set up. This is undermined however, by the lack of trained staff. Moreover, there are frequent interruptions during in their assigned work schedule owing to factors such as unplanned emergency procedures, assisting for critical events, disjointed and missing medical supply etc. This increases the risks of some omissions in their care delivery amidst such stacking of cognitive and physical loads. However, merely increasing the number of nurses in a patient care unit may not be a panacea if the environment in which they work is not conducive to clinical decision making. There should be task organization skill simulations to improve their ability to manage such high cognitive managerial tasks¹⁰.

The importance of effective clinical leadership in ensuring safe and efficient care has been reiterated time and again. Nurses need to gain autonomy over their own practicing behavior in order to improve their patients’ clinical outcome¹¹. Effective model study should be framed to upraise the standards of such pivotal role playing the front-line staffs^12,13. Future shortages of nurses may be unpreventable, but making provisions for effective interdisciplinary teamwork, coupled with pivotal approaches for determining quality insurance and promoting safe environments for patients, could help mitigate their harmful impacts¹⁴.

A similar study carried out to assess the knowledge of nurses regarding chest physiotherapy found that though they had good results in their clinical performances, with regards to clinical knowledge encompassing the same, they ironically performed poor¹⁵. Almost 67% of them were not aware about indication of postural drainage while 76% were not aware about definition of percussion and vibration¹⁵. Similar discrepancy with regards to task performance and the knowledge regarding underlying rationales for the same have been seen in our study as well. Our study also revealed that despite understanding that chest physiotherapy is an essential strategy to minimizing pulmonary complications, none of the nurses were able to correctly outline different components of the same namely positioning, percussion, vibration, squeezing and finally suctioning^16,17.

Amidst the scenario of having an extreme shortage of effective manpower in the health sector on the one hand and the prevalence of huge discrepancy between knowledge of the tasks being performed among the healthcare practitioners on the other; the application of care bundle approaches could promote the notion of “effective tasking through minimal manpower”. This can help improve the standards of the health care providers as well as safeguard patient’s health and safety.

There are certain limitations to our study. Foremost being inclusion of nurses from Neurosurgical units of only three teaching hospitals of our country. One of the prevailing limiting factors in carrying out such observational study is the risk of coherent bias in the results due prior knowledge of such study among the probable study groups from their peers who already participated in the study. However, the results can further be validated through its multicentric application throughout national and international hospitals with inclusions of nurses from other surgical subspecialties as well as those practicing in the general incentive care units. There is also pivotal need in assessing the effect of such patient focused care bundle approaches in minimizing complications among the patients following its application. The fundamental rational of this study is to promote inclusions of patient care bundle approaches in managing patients to safeguard our patients’ health.

Conclusion

The initiation of patient focused care bundle approaches is imperative to improving health delivery standards especially in low income nations. Such initiatives can promote health care provider autonomy on patient care, as well as assure better patient outcomes by minimizing complications.
